[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0025] Specific examples are given below.

[0026] See also Figure 1 - Figure 5 The utility model provides a composite glue brushing equipment for producing packaging bags, comprising a machine body 1, a conveying roller 2, and a packaging film 3. Both ends of the conveying roller 2 are rotatably connected to the inner wall of the machine body 1, and one side of the conveying roller 2 is in contact with one side of the packaging film 3. A smoothing roller 21 is in contact with one side of the top of the packaging film 3, and both ends of the smoothing roller 21 are rotatably connected to a slider 10. A plurality of guide rollers 5 are rotatably connected inside the machine body 1, and one side of each guide roller 5 is rotatably connected to one side of the packaging film 3. A glue storage box 13 is fixedly connected to the middle of the machine body 1, and a mesh roller 4 is rotatably connected to the middle of the glue storage box 13. Both ends of the mesh roller 4 are rotatably connected to the inner walls of both sides of the machine body 1, and one side of the top of the mesh roller 4 is rotatably connected to one side of the packaging film 3. Protective plates 41 are provided on both sides of the mesh roller 4, and a scraper 42 is fixedly connected to the middle of each protective plate 41, and two scrapers 42 are symmetrically arranged on both sides of the mesh roller 4. Both ends of each protective plate 41 are fixedly connected to a connecting block 43, and an opening slot 14 is provided on the outer side of each connecting block 43, and each opening slot 14 is provided on the inner wall of the body 1. A second push rod 15 is fixedly connected to one side of each opening slot 14, and one end of each second push rod 15 is fixedly connected to the connecting block 43. A second spring 16 is sleeved on the outer side of each second push rod 15, and one end of each second spring 16 is fixedly connected to the connecting block 43.

[0027] During operation, the packaging film 3 is passed through the conveying roller 2 and the smoothing roller 21 by lifting the smoothing roller 21, and then the packaging film 3 is attached to the outside of the multiple guide rollers 5. When one side of the packaging film 3 needs to be brushed with glue, the packaging film 3 is pulled between the conveying roller 2 and the smoothing roller 21 and the outside of the multiple guide rollers 5 by the winding device, so that the packaging film 3 is constantly in contact with the mesh roller 4. The rotation of the mesh roller 4 can adsorb the glue inside the glue storage box 13, so that the glue sticks to the surface of the mesh roller 4. The protective plate 41 can reduce the splashing of glue when the mesh roller 4 rotates. The scraper strip 42 fixed in the middle of the protective plate 41 can be used to scrape off the excess glue on the surface of the mesh roller 4 to ensure the uniformity of the glue thickness. The contact between the top of the mesh roller 4 and one side of the packaging film 3 is used to make the glue stably adhere to one side of the packaging film 3, thereby completing the brushing of the packaging film 3. When the thickness of the glue needs to be adjusted, the second push rod 15 inside the open slot 14 is controlled to operate, and the contraction of the second push rod 15 can drive the connecting block 43 to move inside the open slot 14, so that the protective plate 41 and the scraper strip 42 gradually move away from the two sides of the mesh roller 4. The elastic force of the second spring 16 can increase the service life of the structure, and the thickness of the glue can be adjusted with the adjustment of the scraper strips 42 on both sides. It is convenient for the staff to operate, reduce the labor of the workers, improve the compound efficiency of the packaging bag production, and improve the practicality of the equipment.

[0028] Further, such as Figure 1 and Figure 2 As shown, a driving motor 6 is fixedly connected to one side of the machine body 1, and one end of the output shaft of the driving motor 6 is fixedly connected to one end of the mesh wire roller 4, and a driven wheel 7 is fixedly connected to the outer wall of one end of the mesh wire roller 4. The outer wall of the driven wheel 7 is rotatably connected to a transmission belt 8, and the inner wall of the other end of the transmission belt 8 is rotatably connected to another transmission belt 8, and the inner wall of the other transmission belt 8 is fixedly connected to the outer wall of one end of the conveying roller 2. The conveying roller 2 and the mesh wire roller 4 rotate synchronously via the driven wheel 7 and the transmission belt 8. The outer walls of one end of the two top guide rollers 5 are fixedly connected to the driven wheel 7, and a transmission belt 8 is also rotatably connected between the outer walls of the two driven wheels 7. Another driving motor 6 is provided on one side of one guide roller 5, and one side of the other driving motor 6 is fixedly connected to one side of the machine body 1, and the output shaft of the other driving motor 6 is fixedly connected to one end of one mesh wire roller 4.

[0029] During operation, when the packaging film 3 needs to be glued, two driving motors 6 are started at the same time, and one driving motor 6 is used to drive the mesh roller 4 to rotate, so that the driven wheel 7 fixed to the outside of the mesh roller 4 rotates synchronously. The transmission belt 8 is then used to make the conveying roller 2 rotate synchronously with the mesh roller 4, and the rotation of the conveying roller 2 can ensure the stability of the movement of the packaging film 3. It prevents the mesh roller 4 and the packaging film 3 from being disconnected when brushing glue, and ensures the stability of glue application. The output shaft of another driving motor 6 is used to drive a guide roller 5 to rotate, and the driven wheel 7 and the transmission belt 8 are also used to make the two guide rollers 5 on the top rotate synchronously. The rotation of the guide roller 5 can reduce the tension generated by the packaging film 3 when it is pulled, and reduce the breakage of the packaging film 3 during the compounding process. And when the guide roller 5 rotates, it contacts the side of the packaging film 3 that is not coated with glue, which can prevent the glue on the surface of the packaging film 3 from falling off during transportation, thereby improving the compounding effect of the packaging bag production.

[0030] Further, such as Figure 3 As shown, two rectangular grooves 9 are provided at one end of the body 1, and each rectangular groove 9 is provided on the outside of the slider 10. A first push rod 11 is fixedly connected to one side of the top of each slider 10, and the other end of each first push rod 11 is fixedly connected to the inner wall of one side of the rectangular groove 9. Each slider 10 is slidably connected inside the rectangular groove 9 via the first push rod 11. A first spring 12 is fixedly connected to one side of each slider 10, and each first spring 12 is sleeved on the outside of the first push rod 11, and the other end of each first spring 12 is fixedly connected to one side of the rectangular groove 9.

[0031] During operation, the first push rod 11 contracts to drive the slider 10 to lift inside the rectangular groove 9, so that the smoothing roller 21 is separated from the top of the conveying roller 2. The packaging film 3 can be stably passed through the conveying roller 2 and the smoothing roller 21, which is convenient for the staff to operate and improves the efficiency of the equipment. The elastic force of the first spring 12 can improve the anti-seismic effect of the equipment and reduce the jamming and breaking of the packaging film 3 when applying glue. The first push rod 11 is then used to push the slider 10 down, so that the smoothing roller 21 falls on the top of the packaging film 3 again. The conveying roller 2 and the smoothing roller 21 can prevent the packaging film 3 from being dislocated or wrinkled during the process of applying glue, thereby improving the effect of applying glue to the packaging film 3.

[0032] Working principle: The contraction of the first push rod 11 can drive the slider 10 to lift up inside the rectangular groove 9, so that the smoothing roller 21 is separated from the top of the conveying roller 2, and the packaging film 3 can be stably passed through the conveying roller 2 and the smoothing roller 21. Then the first push rod 11 is used to push the slider 10 down, so that the smoothing roller 21 falls on the top of the packaging film 3 again. The conveying roller 2 and the smoothing roller 21 can prevent the packaging film 3 from being dislocated or wrinkled during the process of applying glue. Then the packaging film 3 is attached to the outside of multiple guide rollers 5. When the packaging film 3 needs to be applied with glue, two drive motors 6 are started at the same time, and one drive motor 6 is used to drive the mesh roller 4 to rotate, and the transmission belt 8 is used to make the conveying roller 2 and the mesh roller 4 rotate synchronously. Then the output shaft of another drive motor 6 is used to drive a guide roller 5 to rotate, and the driven wheel 7 and the transmission belt 8 are also used to make the two guide rollers 5 on the top rotate synchronously. The rotation of the guide roller 5 can reduce the tension generated when the packaging film 3 is pulled again. The rotation of the mesh roller 4 can be used to absorb the glue inside the glue storage box 13, so that the glue sticks to the surface of the mesh roller 4. The scraper bar 42 fixed in the middle of the protective plate 41 can then be used to scrape off the excess glue on the surface of the mesh roller 4, so that the glue is stably adhered to one side of the packaging film 3, thereby completing the glue application work of the packaging film 3. When the thickness of the glue application needs to be adjusted, the contraction of the second push rod 15 can drive the connecting block 43 to move inside the opening groove 14, so that the protective plate 41 and the scraper bar 42 gradually move away from the two sides of the mesh roller 4, and the thickness of the glue retention can be adjusted with the adjustment of the scraper bars 42 on both sides.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
