Fault 4: Bindery Unit Failure on Wireless Binding Line
(1) The back rubber wheel is different in operation or stuck.
Fault analysis: The running of the back rubber wheel is driven by the gear on the top of the rubber wheel and the power part of the glue binding machine. If the hot melt glue sticks to the gear, it affects the gear meshing operation. It needs to be cleaned in time, but some hot melt Poor quality of glue is also the cause of failure. If the hot melt adhesive has poor anti-aging ability, the amount of titanium dioxide additive is large, and the shaft and the seal ring wear for a long time. The aged material of the hot melt adhesive enters the sleeve and blocks the inlet of the oil, so that the lubricant cannot enter the sleeve. Under-lubrication, abnormal noise, if not eliminated, the rubber wheel may be broken.
Remedy: First, remove the adhesive from the back-adhesive pan, remove the back-adhesive wheel and the shaft, clean the foreign matter on the sleeve, and add a small amount of high-temperature resistant butter after clearing the oil. Then, polish the shaft, replace the damaged seals on both sides, and install a proper amount of lubricant. In the end, the hand wheel is pressed and the back rubber wheel runs freely, 'pull it into the operating station again.
(2) Glueless books and magazines have no side glue, causing the cover to fail.
Failure analysis: Binder side rubber wheel falls into the plastic pot during operation, causing some rubber-bound books without side glue.
Remedy: Observe the positioning axis of the side rubber wheel carefully. There is a mark pressed by the top wire at the location. Measure the thickness of the side rubber wheel and the length of the positioning plate to the top wire and increase the length by 0.2 mm. Leave it as the side rubber wheel. Run the gap. Use a 2mmX5mm platform on the top silk imprinting station. After the original positioning shaft and side rubber wheel are installed in the station, tighten the fixing screws. Because the short axis has a step, it not only restricts the rotation of the positioning axis, but also the positioning axis cannot move up and down. After this processing and positioning, the problem of no side glue is solved, and the side rubber wheel rarely falls.
The disc package machine failure and exclusion
Fault 1: BBY45/8 disc pack machine shutdown failure
Fault analysis: When the cover is transported to the back-up platform, it can easily cause a malfunction of the cover detection photoelectric switch, resulting in frequent machine shutdowns. As long as it is downtime, at least 3 book's glue quality is affected. After shutting down, the glue layer can not be properly brushed onto the back of the book; or the rubber wheel is stopped, causing uneven glueing, and the booklet is scattered; or after the glue is dry, it is easy to drop the cover. Through the exchange of the two disc packs of the local computer memory, the inspection and analysis of the photoelectric switch, proximity switch, and the working condition of the valve, it is considered that the simplest method is to increase the force of the sealing wheel and make the cover convey. Speed ​​up. However, due to the shadow of the bridge over the cover, the adjustment effect is not good, there is no downtime when the package size is small, and when the package size is larger than 32, the failure occurs again.
Remedy: Through two contrast adjustments, the possibility of electrical failure is ruled out. When the platform is at its lowest point, adjust the connecting rods of the left and right shelves; make the connecting shaft and the rubber roller contact with each other in advance; when the cover output is found when the test machine is turned on, the solid platform has just fallen to the lowest point, and the cover is not Blocking will occur. Therefore, the commissioning personnel are required not only to know whether the photoelectric switch is working properly, but also to be diligent in observing the equipment, to be able to accurately determine the location of the failure and to resolve it in time.
Fault 2: When the cover has no side glue or encapsulation, the book block collides with the side of the plastic pot. Failure analysis: The disc is wrapped on the big rubber wheel on the side of the machine. The two 103 bearings are blocked by the hot melt adhesive's aging material. As a result, the bearing does not move, the large rubber wheel on the side glue pot does not move, the side glue system has no power, and the side rubber wheel has no glue. At this time, the side glue pot is easily knocked open by the book block.
Remedy: Remove the set screw first, then remove the lock mother on the big rubber wheel, remove the retainer, remove the 103 bearing, remove the aging hot melt adhesive residue, replace the bearing under the high temperature seal ring, manual test run Afterwards, reload the original station.
Fault 3: BBY40/5 disc packer
Fault analysis: mainly the loosening of the locating ring on the adjusting screw of the rubber wheel frame of the upper primer device, the chain is driven downwards after the machine runs, causing the height of the bottom rubber wheel to drop, which is inconsistent with the height of the second falling platform, and the first The rubber wheels on the bottom cannot open the book block, causing the glue to be impractical.
Remedy: Loosen the two hexagon socket screws of the U-shaped plate, loosen the adjusting screw, and fix the retaining ring on the adjusting screw according to the thickness of the U-shaped plate. Finally adjust the first rubber on the bottom to 8.5mm from the bottom of the book holder, which is the same as the height of the second book landing platform.
ZYH660 Hybrid Folding Machine Troubleshooting
Fault 1: Hunan Xinshao ZYH660 paper folding machine folding folder Fault Analysis: The hollow sleeve and the outer seal sleeve of the suction wheel body wear, resulting in the wind turbine continuous gas, continuous paper feed, waste is greater.
Remedy: According to the air supply control principle of the ZYH920 hybrid folder wind wheel, it can be modified on its own.
First, remove the valve sleeve that is connected to the solenoid core screw. The hexagonal head of the hexagonal head screw of M1 2 X100 is machined into a cone top. The other end of the screw rod is drilled with a deep hole of M5 X 25 and is connected with the electromagnet screw, and a bung spring is placed in the middle to ensure that the ejector rod runs freely. In the air path connected to the wind wheel, use "Plastic King" (polytetrafluoroethylene) to process the outside diameter and the inner diameter of the solenoid valve mounting base, the height of the column is 20mm, and the inner diameter L is the diameter of the middle 6mm plastic column. The top of the rod is matched with the top of the rod, and the other end is connected with the wind wheel gas circuit, and then it is fixed. Due to the use of "Plastic King", the plastic column uses more light and better airtightness. When the solenoid valve is closed, the air path is opened. When the solenoid valve is closed, the breather is reset to close the suction, and the closing performance can be controlled by adjusting the relative position of the top rod and the solenoid valve, and four or five years are available, and the effect is good.
Failure 2: Purple macro, ZYH660D second folding folder folding machine in the folded paper, the bottom angle is not uniform, wrinkle or break
Failure analysis; The mechanism of the press ball of the machine is different from that of the lake 'South Xinshun Folding Machine'. The upper and lower press bars are separated by a large distance, and it is in Hunan when it is folded at 65g/m2 paper. There is no difference between Xinshun folding machines but the problem is more obvious when folding paper. The speed of the hybrid folding machine is faster, and the medium impact force of the paper on the conveyor belt against the rear baffle is bound to be larger. When the spacing between the upper and lower press bars is large, the paper is likely to be curled; and the curling on both sides is inconsistent, and the rear end of the fold is not uniform. The edges are naturally missing and some of the folded pages are out of tolerance.
Remedy: Reduce the machine speed and reduce the backlash of the paper. The discharge of the ball can also be adjusted accordingly. Two rows of pressure balls are pressed on the sides of the back gauge to prevent the paper from curling upwards. In the front edge of the back gauge, the paper presses on four pressure balls in a row to prevent the paper from retracting, resulting in a misalignment. Adjust the cam feed time of the proximity switch. When the paper is in place, the folding knife will fall. Reduce the paper feed back to the back of the paper. The middle punch force will prevent the fold from wrinkling. Adjust the descent depth of the knife to prevent it from being carried away by the folding rollers when the machine is inching.
Judging whether the knife is falling too deep, just observe that the paper is taken away by the folding roller; and the folding knife does not start to lift too much. The edges of the paper are curled unevenly, and the folding knife is lowered too deeply. At this time, the folded paper is easy to break. The pressure of the edge of the folding roll can be adjusted to a small amount and the folding knife can be raised. On the side where the paper is not conveyed properly, pressurize the ball to increase the pressure and adjust the feeding belt so that the tension is consistent. In addition, ensure that the speed of the paper is the same after the paper is pulled out from the tenth folding fence, and then use the • indentation knife to provide the condition for the second fold. By adjusting the placement of the pressure ball, the pressure adjustment of the folding roller, • The depth of the folding knife, the degree of adjustment, the paper feeding time, the adjustment of the knife time, and the installation pressure. Knife: The method, the thin and soft paper of crescent, the second folds the bottom corners, wrinkles or breaks. Failure of the mouth.
