Description

Technical Field

[0001] The utility model relates to the technical field of tobacco machinery, in particular to a positioning device for a sealing ring of a second rubber cylinder bearing sleeve of a packaging machine. Background Art

[0002] Equipment maintenance is of great significance for the normal operation of equipment and the extension of equipment life. The parts and components of the packaging machine equipment should be regularly maintained and cleaned according to the work plan. In daily production, the second glue cylinder glue wheel shaft of the YB45 small box packaging machine needs to be lubricated and maintained. The grease gun adds grease to the glue wheel shaft through the oil circuit for lubrication and maintenance. When the grease is added in excess and the excess grease cannot overflow in time, the bearing sleeve seal ring is subjected to excessive force and axial displacement or looseness occurs, which causes the glue to penetrate into the bearing sleeve and cause grease contamination, causing excessive heating of the bearing, aggravating bearing wear and even failure. Usually, only the bearing and the bearing sleeve seal ring here need to be replaced to ensure the normal glue coating of the glue cylinder, but it is limited to the original design of the glue cylinder. When replacing the bearing, the entire glue cylinder needs to be disassembled and the glue wheel removed before replacement, which takes a long time and has a large maintenance workload. This situation will also occur after replacing the new bearing and bearing sleeve seal ring. Utility Model Content

[0022] Example

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the technical solution in the embodiment of the present application effectively solves the original design of the glue cylinder. When replacing the bearing, the entire glue cylinder needs to be disassembled and the upper glue wheel needs to be removed for replacement, which takes a long time and has a large maintenance workload. In addition, this technical problem will also occur after replacing the new bearing and the bearing sleeve sealing ring. The overall idea is as follows: A positioning device for the bearing sleeve sealing ring of the second glue cylinder of a packaging machine, comprising a positioning device 1, a glue storage tray 2, an upper glue wheel bracket 3, a second glue cylinder upper glue wheel shaft 4, a bearing sleeve 5, a connecting block 6, a screw 7, and a bearing 8. The upper glue wheel bracket 3 is installed above the glue storage tray 2, the screw 7 is installed on the upper glue wheel bracket 3, and the connecting block 6 is installed on the surface of the screw 7. The positioning device 1 is in the shape of a flat rectangular parallelepiped. A hollow arch-shaped arc groove is provided at the lower part of the device 1, and a handle is connected to the upper part. One end of the positioning device 1 is straight and close to the bearing sleeve 5. The width of the arc groove is equal to the width of the rubber wheel shaft 4 on the second rubber cylinder, and the diameter of the arc groove is equal to the diameter of the rubber wheel shaft 4 on the second rubber cylinder. Sealing rings 9 are provided on both sides of the left and right sides of the bearing 8. There is a connecting block 6 on the right side of the rubber wheel shaft 4 on the second rubber cylinder, which forms a coupling with the connecting block at the power output end of the transmission box, has a positioning function for the sealing ring 9 on the right side of the bearing 8, and positions the sealing ring 9 on the right side. The rubber wheel shaft 4 on the second rubber cylinder is arranged inside the rubber wheel bracket 3, and the rubber wheel shaft 4 on the second rubber cylinder is respectively provided with an oil inlet 10 and an oil outlet 11, and the bearing sleeve 5 is sleeved on the bearing 8. When performing maintenance and lubrication on the glue wheel shaft 4 and the bearing 8 of the second glue cylinder of the trademark paper of the packaging machine, before lubrication, first hold the handle of the positioning device 1 to make the positioning device 1 close to the glue wheel shaft 4 of the second glue cylinder. At this time, the arch opening of the positioning device 1 faces downward and is stuck on the glue wheel shaft 4 of the second glue cylinder. At the same time, the positioning device 1 is close to the bearing sleeve 5 of the glue wheel shaft 4 of the second glue cylinder. When lubricating, use a grease gun to add grease to the glue wheel shaft 4 of the second glue cylinder through the oil inlet 10, and press the positioning device 1 with your hand to prevent the axial displacement of the sealing ring 9 on the left side of the bearing due to force, and slowly inject grease until the grease overflows from the oil outlet 11, indicating that the grease has reached the amount to meet the lubrication demand. At this time, stop injecting grease. After lubrication, take out the positioning device 1, and clean the grease at the oil outlet 11 and the oil inlet 10 with a rag to complete the maintenance and lubrication.

[0024] In view of the problems existing in the prior art, the utility model provides a positioning device for the sealing ring of the bearing sleeve of the second glue cylinder of the packaging machine. The positioning device has a simple structure, is easy to operate, has low cost and safe and reliable sealing, protects the bearings and sealing rings of the glue wheel shaft of the second glue cylinder of the packaging machine's trademark paper, improves production efficiency and stabilizes the production process.

[0025] Working principle:

[0026] The first step is to maintain and lubricate the glue wheel shaft 4 and bearing 8 of the second glue cylinder of the packaging machine label paper. Before lubrication, first hold the handle of the positioning device 1 to make the positioning device 1 close to the glue wheel shaft 4 of the second glue cylinder. At this time, the arch opening of the positioning device 1 faces downward and is stuck on the glue wheel shaft 4 of the second glue cylinder. At the same time, the positioning device 1 is close to the bearing sleeve 5 of the glue wheel shaft 4 of the second glue cylinder;

[0027] The second step is to use a grease gun to add grease to the rubber wheel shaft 4 on the second rubber cylinder through the oil inlet 10 during lubrication, and press the positioning device 1 by hand to prevent the sealing ring 9 on the left side of the bearing from axial displacement due to force, and slowly inject grease until the grease overflows from the oil outlet 11, indicating that the grease has reached the amount that meets the lubrication requirements, and stop injecting grease at this time;

[0028] The third step is to take out the positioning device 1 after lubrication, and clean the grease of the oil outlet 11 and the oil inlet 10 with a rag to complete the maintenance and lubrication.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods.
