Description

Technical Field

[0001] This utility model relates to the field of pet pee pad production technology, and in particular to a multi-layer composite production line for pet pee pads. Background Technology

[0002] Pet pee pads are absorbent materials, primarily composed of cotton pulp and superabsorbent polymers. They are used to absorb pet excrement, achieving an absorption rate of dozens of times their own volume. After absorbing water, they expand into a jelly-like consistency, preventing leakage and stickiness. The special embossing on the surface of the diaper quickly diverts liquid. Containing advanced antibacterial agents, they provide long-lasting deodorization and odor elimination. Pet pee pads undergo a composite treatment process during production.

[0003] In existing pet pee pad production, the upper covering layer typically requires embossing. Over time, the embossing roller's surface pattern gradually wears down due to frequent contact and compression with the material and support rollers. When the wear reaches a certain point, the embossed pattern becomes unclear and incomplete, affecting the appearance and feel of the upper covering layer and failing to meet product quality requirements. Furthermore, the inconvenience of easily replacing the embossing roller makes the replacement process cumbersome, thus reducing the production line's efficiency. Therefore, this invention proposes a multi-layer composite production line for pet pee pads to solve these problems. Utility Model Content

[0004] To address the aforementioned issues, this utility model proposes a multi-layer composite production line for pet urine pads, which solves the problem in the prior art where it is inconvenient to easily replace the embossing roller, making the replacement process cumbersome and reducing the working efficiency of the production line.

The mounting base has a connecting block inside. The connecting block has a fixing hole inside. The fixing hole has a positioning pin inside.

[0007] A further improvement is that the mounting base and the connecting block form an engaging structure, and the fixing hole and the positioning pin form an engaging structure.

[0008] A further improvement is that two mounting bases are provided below the mounting plate, and the two mounting bases are symmetrically distributed about the central axis of the mounting plate.

[0009] A further improvement is made in that: the fixing mechanism includes a positioning hole, a movable rod, a positioning plate, and a telescopic spring. The positioning hole is opened through both ends of the movable plate, and the movable rod is installed through the interior of the positioning hole. The positioning plate is installed at the bottom end of the movable rod, and a telescopic spring is provided on the outer wall of the movable rod.

[0017] To deepen the understanding of this utility model, the following detailed description of the utility model will be provided in conjunction with the embodiments. These embodiments are only used to explain the utility model and do not constitute a limitation on the scope of protection of the utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a multi-layer composite production line for pet urine pads, including a base plate 1. A side plate 2 is installed at the rear end of the top of the base plate 1. A bottom material roller 3 is installed below the front end of the side plate 2. An absorbent layer material roller 4 is installed at the middle position of the front end of the side plate 2. An upper coating layer material roller 5 is installed above the front end of the base plate 1. An adhesive applicator 6 is installed above both the bottom material roller 3 and the absorbent layer material roller 4. A lower pressing roller 7 is installed at the front end of the base plate 1. An upper pressing roller 8 is installed above the lower pressing roller 7. A conveyor roller 9 is installed above the side plate 2. An embossing mechanism is provided on one side of the conveyor roller 9 at the front end of the side plate 2. A conveying structure 17 is installed above the front end of the side plate 2. A support plate 18 is installed on the inner side of the conveying structure 17. An mounting frame 19 is installed above the support plate 18. A cylinder 20 is installed at the top of the mounting frame 19. A movable plate 21 is installed at the bottom of the cylinder 20. A cutting blade 22 is installed at the bottom of the movable plate 21. Fixing mechanisms are provided on both sides of the cutting blade 22. An infrared sensor is installed below the movable plate 21.

[0019] The embossing mechanism includes a support roller 10, a mounting plate 11, a printing roller 12, a mounting base 13, a connecting block 14, a fixing hole 15, and a positioning pin 16. The support roller 10 is mounted on the front end of the side plate 2. The mounting plate 11 is mounted above the support roller 10, and the mounting base 13 is mounted at the bottom end of the mounting plate 11. The mounting base 13 has a connecting block 14 inside, and a fixing hole 15 is opened inside the connecting block 14. A positioning pin 16 is set inside the fixing hole 15. The mounting base 13 and the connecting block 14 form a locking structure, and the fixing hole 15 and the positioning pin 16 form a locking structure. Two mounting bases 13 are arranged below the mounting plate 11, and the two mounting bases 13 are symmetrically distributed about the central axis of the mounting plate 11. The printing roller 12 can be used to print on the upper covering layer. When the printing roller 12 needs to be replaced, the positioning pin 16 is removed from the inside of the fixing hole 15. At this time, the connecting block 14 can be removed from the inside of the mounting base 13. The printing roller 12 is then removed, and the new printing roller 12 is taken out. The connecting block 14 is inserted into the inside of the mounting base 13, and the positioning pin 16 is inserted into the inside of the fixing hole 15 to fix the position of the printing roller 12. The printing roller 12 can be easily disassembled and installed, making it more convenient and quick to replace. It also makes it more convenient and efficient to change patterns. At the same time, the printed pattern is clearer and more complete, without affecting the appearance and feel of the covering layer on the pet pee pad, thus greatly improving the working efficiency of the production line.

[0020] The fixing mechanism includes a positioning hole 25, a movable rod 26, a positioning plate 27, and a telescopic spring 28. The positioning hole 25 is formed through both ends of the movable plate 21. The movable rod 26 is inserted through the interior of the positioning hole 25. The positioning plate 27 is installed at the bottom end of the movable rod 26. The telescopic spring 28 is installed on the outer wall of the movable rod 26 and is installed between the movable plate 21 and the positioning plate 27. The cross-section of the positioning hole 25 is larger than the cross-section of the movable rod 26. The positioning hole 25 and the movable rod 26 form a sliding structure. In use, the starting cylinder 20, guided by the guide hole 23 and the guide rod 24, utilizes the cylinder 20... The moving plate 21 moves downward, which in turn moves the cutting blade 22 downward. At this time, the two positioning plates 27 come into contact with the pet pee pad, fixing its position. The cutting blade 22 continues to move downward, and the moving rod 26 moves inside the positioning hole 25. The elastic force of the telescopic spring 28 is used to fix the pet pee pad, making the cutting of the pet pee pad more stable and the cutting effect better. This greatly improves the practicality of the production line. Since the cylinder 20 moves at a relatively fast speed and the conveying structure 17 conveys at a relatively slow speed, fixing the pet pee pad during cutting will not affect the production speed and quality of the pet pee pad.

[0021] The mounting bracket 19 has a through guide hole 23, and a guide rod 24 is installed through the guide hole 23. The bottom end of the guide rod 24 is connected to the top end of the movable plate 21. In use, the cooperation between the guide hole 23 and the guide rod 24 can limit the movement of the movable plate 21, making the movable plate 21 more stable when moving.

[0022] Working principle: First, the operator pulls the bottom layer material on the base material roller 3 between the lower pressing roller 7 and the upper pressing roller 8, and conveys it using the conveying roller 9. Then, the absorbent layer material on the absorbent layer roller 4 is pulled between the lower pressing roller 7 and the upper pressing roller 8, and conveyed using the conveying roller 9. Finally, the upper coating layer material roller 5 is pulled by the conveying roller 9 between the support roller 10 and the printing roller 12, and finally passes through the lower pressing roller 7 and the upper pressing roller 8. The glue coating machine 6 can then coat the base material roller 3 and the absorbent layer roller 4. The upper part is sprayed with adhesive. The upper coating layer roller 5 is printed using the cooperation of the support roller 10 and the printing roller 12. The pet pee pad is pressed using the lower pressing roller 7 and the upper pressing roller 8. Finally, the pressed pee pad is pulled onto the conveyor structure 17 for traction. The conveyor structure 17 transports the pee pad, and the position of the pet pee pad can be determined using the infrared sensor below the movable plate 21. When cutting is required, the cylinder 20 is activated at the guide hole 23 and... Guided by the guide rod 24, the cylinder 20 drives the movable plate 21 to move downward, thus driving the cutting blade 22 to move downward. At this time, the two positioning plates 27 contact the pet pee pad, fixing the position of the pet pee pad. The cutting blade 22 continues to move downward, and the movable rod 26 moves inside the positioning hole 25. The elastic force of the telescopic spring 28 is used to fix the pet pee pad, and the cutting blade 22 cuts the pet pee pad. Since the cylinder 20 moves at a relatively fast speed, while the conveying speed of the conveying structure 17 is relatively slow, fixing the pet pee pad during cutting will not affect the production speed and quality of the pet pee pad. When the printing roller 12 needs to be replaced, the positioning pin 16 is removed from the inside of the fixing hole 15. At this time, the connecting block 14 can be removed from the inside of the mounting base 13. The printing roller 12 is removed, and then the new printing roller 12 is taken out. The connecting block 14 is inserted into the inside of the mounting base 13, and the positioning pin 16 is inserted into the inside of the fixing hole 15 to fix the position of the printing roller 12.
