[0014] 1. This utility model sets a receiving box on the base and at the bottom of the conveyor belt, and then sets a scraping glue mechanism inside the receiving box. The scraping glue strip and the sponge block abut against the conveyor belt. In addition, a hollow tube with a nozzle is set above the conveyor belt. Steam can be introduced into the hollow tube and sprayed out through the nozzle to soften the residual glue on the conveyor belt. Then, the residual glue on the conveyor belt can be recycled by the scraping glue strip and the sponge block.

[0015] 2. This utility model sets a fixed plate on the bracket, and sets a spring, a baffle and a travel limit block at the bottom of the fixed plate.

The air inlet pipe 111 is connected to pressurized steam through a hose, and then discharged through the nozzle 12 at the bottom of the hollow tube 11.

[0023] Please see Figure 3A fixed plate 6 is fixedly connected to the support 3. Multiple springs 7 are fixedly connected to the bottom of the fixed plate 6. A baffle 8 is fixedly connected to the bottom of each spring 7, and the baffle 8 abuts against the conveyor belt 2. The springs 7 allow elastic force to be applied to the baffle 8. A travel limit block 9 is fixedly connected to the bottom of the fixed plate 6, and the travel limit block 9 is fitted inside the springs 7. The travel limit block 9 limits the travel of the baffle 8 and provides a reaction force.

[0024] Please see Figure 1-4 The receiving box 4 has a scraping mechanism 5 inside. The scraping mechanism 5 includes a bracket 51 fixedly connected to the bottom of the receiving box 4. An adjusting rod 52 is threadedly connected inside the bracket 51 and passes through the bracket 51. A support plate 53 is fixedly connected to the top of the adjusting rod 52. A scraping strip 54 is fixedly connected to the upper left side of the support plate 53 and abuts against the conveyor belt 2. The scraping mechanism 5 scrapes off the glue on the conveyor belt 2. A box body 55 is fixedly connected to the upper right side of the support plate 53. A slider 56 is slidably connected to the inside of the box body 55. A sponge block 57 is fixedly connected to the upper end of the slider 56. The sponge block 57 passes through the box body 55 and is slidably connected to the box body 55. The sponge block 57 contacts the conveyor belt 2. A second spring 58 is provided inside the box body 55. One end of the second spring 58 is fixedly connected to the slider 56, and the other end of the second spring 58 is fixedly connected to the inner surface of the box body 55. Spring 58 allows elastic force to be applied to sponge block 57 via slider 56, ensuring that sponge block 57 remains in contact with conveyor belt 2.

The guide post 59 guides the lifting and lowering adjustment of support plate 53.

[0025] The specific implementation process of this utility model is as follows: In use, after the cardboard is coated with glue on the conveyor belt 2, the air inlet pipe 111 is connected to the hose and the pressurized steam source, so that the glue is sprayed out through the nozzle 12 to soften the residual glue on the conveyor belt 2. Then, by rotating the adjusting rod 52, the adjusting rod 52 moves with the thread between it and the bracket 51, causing the support plate 53 to move upward. This causes the glue scraper 54 and the sponge block 57 on the support plate 53 to come into contact with the conveyor belt 2. The removal of the glue scraper 54 and the sponge block 57 can then recycle the residual glue on the conveyor belt 2. Moreover, the adjustable nature of the glue scraper 54 can be used to adjust the tension of the conveyor belt 2, thereby preventing the conveyor belt 2 from slipping.
