DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For further information, see Figure 4A conveying roller 9 is fixedly connected to one side of the moving block 23, a limiting groove 22 is provided on the inner wall of the mounting groove 21, and guide blocks 24 are integrally formed on both sides of the outer wall of the moving block 23. The guide blocks 24 are slidably located inside the limiting groove 22. By setting the guide blocks 24 slidably located inside the limiting groove 22, the moving trajectory of the moving block 23 is further stabilized, so that the moving block 23 cannot deviate from the predetermined direction during the moving process.

[0027] In the specific implementation, the infusion pump 7 is first started to transfer the glue in the glue storage box 5 to the glue storage tank 19 through the infusion tube 8, and then the user starts the motor 3 to make the winding roller 10 start to rotate, so as to roll the label paper 2 onto the outer wall of the winding roller 10. During the winding process, the label paper 2 passes over the top of the support rod 4 and then passes through the bottom of the glue coating roller 6. When passing through the bottom of the glue coating roller 6, the rotating glue coating roller 6 will apply the glue in the glue storage tank 19 to the surface of the label paper 2, and then pass through the top of the support rod 4 again and be rolled up to the conveying roller 9 by the winding roller 10. , if the tension on the label paper 2 is too great, the conveying roller 9 will drive the moving block 23 to move upward, and the stretching spring 26 will be directly squeezed during the upward movement of the moving block 23. The stretching spring 26 will increase its resistance to the moving block 23 during the squeezing process, which will keep the label paper 2 on the surface of the conveying roller 9 in a state suitable for transmission. At the same time, after the conveying roller 9 moves upward, the tension on the label paper 2 is reduced and it will not break easily. The winding of the label paper 2 can be completed by the winding roller 10 behind the conveying roller 9.

[0028] By setting up protective components, the integrity and aesthetics of the label stickers are ensured, the product qualification rate is improved, and the production line can operate more stably and continuously, thereby improving production efficiency. Finally, the protective components effectively prevent the label stickers from breaking, and related companies can save these extra costs and improve economic benefits.

[0029] Embodiment 2

[0030] In the inheritance of Example 1, please refer to Figure 1-5 A glue coating device, a main scraper 17 is fixedly installed on one side of the glue coating roller 6, a rotatable reciprocating screw 15 is provided on one side of the main scraper 17, two limit plates 14 are fixedly installed on the outer wall of the reciprocating screw 15, a movable scraper 16 is threadedly connected on the outer wall of the reciprocating screw 15 between the two limit plates 14, a limit plate 18 is fixedly installed on the upper end of the reciprocating screw 15, a limit block 27 is fixedly installed on the upper end of the movable scraper 16, and the limit block 27 is slidably located inside the limit plate 18.

[0031] For further information, see Figure 1A transmission belt 12 is sleeved on the outer wall of the first transmission wheel 11, and a second transmission wheel 13 is fixedly installed on one end of the reciprocating screw rod 15. The other side of the transmission belt 12 is sleeved on the outer wall of the second transmission wheel 13. By arranging that the transmission belt 12 is sleeved on the outer wall of the first transmission wheel 11, and the other side of the transmission belt 12 is sleeved on the outer wall of the second transmission wheel 13, the motor 3 can drive the second transmission wheel 13 to rotate after starting, so that the reciprocating screw rod 15 can rotate without additional power.

[0032] During specific implementation, the label paper 2 will pass through the main scraper 17 during the transmission process after the gluing is completed. The main scraper 17 will evenly spread the glue on the surface of the label paper 2. However, after long-term use, a large amount of glue will remain on the surface of the main scraper 17, and the residual glue will cause the effect of the main scraper 17 to be affected, thereby affecting the quality of the finished product of the label paper 2. In this utility model, the rotation of the reciprocating screw 15 will drive the movable scraper 16 to move back and forth between the two limit plates 14, and one end of the movable scraper 16 is attached to the surface of the main scraper 17. Therefore, the residual glue on the surface of the main scraper 17 can be scraped off during the movement of the movable scraper 16.

[0033] By setting a reciprocating screw 15 on one side of the main scraper 17 and threading a movable scraper 16 on the outer wall of the reciprocating screw 15, the movable scraper 16 can continuously scrape off the residual glue on the surface of the main scraper 17, so that the device can always maintain a uniform thickness when applying glue to the label paper 2, thereby ensuring the quality of the finished label paper 2.

[0034] Working principle: first start the infusion pump 7 to transfer the glue in the glue storage box 5 to the glue storage tank 19 through the infusion tube 8, then the user starts the motor 3 to make the winding roller 10 start to rotate, so as to roll the label paper 2 onto the outer wall of the winding roller 10. During the winding process, the label paper 2 passes over the top of the support rod 4 and then passes through the bottom of the glue coating roller 6. When passing through the bottom of the glue coating roller 6, the rotating glue coating roller 6 will apply the glue in the glue storage tank 19 to the surface of the label paper 2, and then pass through the top of the support rod 4 again and be rolled up to the conveying roller 9 by the winding roller 10. , if the tension on the label paper 2 is too great, the conveying roller 9 will drive the moving block 23 to move upward, and the stretching spring 26 will be directly squeezed during the upward movement of the moving block 23. The stretching spring 26 will increase its resistance to the moving block 23 during the squeezing process, which will keep the label paper 2 on the surface of the conveying roller 9 in a state suitable for transmission. At the same time, after the conveying roller 9 moves upward, the tension on the label paper 2 is reduced and it will not break easily. The winding of the label paper 2 can be completed by the winding roller 10 behind the conveying roller 9.

[0035] During the transmission process after the gluing is completed, the label paper 2 will pass through the main scraper 17, and the main scraper 17 will evenly spread the glue on the surface of the label paper 2. However, after long-term use, a large amount of glue will remain on the surface of the main scraper 17, and the residual glue will affect the effect of the main scraper 17, thereby affecting the quality of the finished product of the label paper 2. In the present invention, the rotation of the reciprocating screw 15 will drive the movable scraper 16 to move back and forth between the two limit plates 14, and one end of the movable scraper 16 is attached to the surface of the main scraper 17. Therefore, the residual glue on the surface of the main scraper 17 can be scraped off during the movement of the movable scraper 16.

[0036] By setting up protective components, the integrity and aesthetics of the label stickers are ensured, the product qualification rate is improved, and the production line can operate more stably and continuously, thereby improving production efficiency. Finally, the protective components effectively prevent the label stickers from breaking, and related companies can save these extra costs and improve economic benefits.

[0037] By setting a reciprocating screw 15 on one side of the main scraper 17 and threading a movable scraper 16 on the outer wall of the reciprocating screw 15, the movable scraper 16 can continuously scrape off the residual glue on the surface of the main scraper 17, so that the device can always maintain a uniform thickness when applying glue to the label paper 2, thereby ensuring the quality of the finished label paper 2.
