[0028] The clamping assembly 2 includes a mounting frame 21. The lower front and rear parts of the mounting frame 21 are fixedly installed at the front and rear positions of the upper middle parts of the two side plates 1. A lifting mechanism 22 is fixedly installed at the upper middle part of the mounting frame 21. A lifting plate 23 is fixedly installed at the bottom of the lifting mechanism 22. A counter-adjustment mechanism 24 is fixedly installed at the lower left and right parts of the lifting plate 23. A movable frame 25 is movably connected to the front and rear parts of the counter-adjustment mechanism 24. A rectangular sleeve 26 is fixedly installed at the lower end of each of the two movable frames 25. A pressure plate 27 is slidably connected to the inner wall of each of the two rectangular sleeves 26. A spring guide shaft 28 is fixedly installed at the upper left and right parts of each of the two pressure plates 27. The upper ends of four adjacent spring guide shafts 28 are fixedly connected to the left and right positions of the top of the inner wall of each of the two rectangular sleeves 26.

[0029] The adjusting adhesive application assembly 3 includes a liquid control tank 31. The upper end of the liquid control tank 31 is fixedly connected to the lower middle part of the lifting plate 23. A quantitative adhesive dispensing mechanism 32 is fixedly installed at the upper front part of the mounting frame 21. The quantitative adhesive dispensing mechanism 32 is connected to the liquid control tank 31. A lead screw 33 is rotatably connected to the front and rear positions of the lower middle part of the liquid control tank 31. A motor 34 is fixedly installed at the lower front part of the liquid control tank 31. The output end of the motor 34 is fixedly connected to the front end of the lead screw 33. A moving plate 35 is threadedly connected to the outer wall of the lead screw 33. An adhesive application roller 36 is rotatably connected to the lower end of the moving plate 35.

[0030] The clamping assembly 2 can fix the front and rear of the sanitary napkin during adhesive application. When processing sanitary napkins of different sizes, rotating the reverse double-threaded rod 241 causes the two movable frames 25 to move in opposite directions via their threaded connection, allowing the two pressure plates 27 to adapt to different sizes of sanitary napkins. Simultaneously, after adhesive application, the adhesive roller 36 moves upward, and the two pressure plates 27 continue to press the surface of the sanitary napkin due to the elastic restoring force of the four spring guide shafts 28, preventing the sanitary napkin from detaching from the electric conveyor belt 4 due to adhesive adhesion, thus enhancing its practicality. The adhesive application assembly 3 can be adjusted to apply adhesive to the surface of the sanitary napkin. The output of the motor 34 drives the lead screw 33 to rotate, and the movable plate 35, threadedly connected to the lead screw 33, drives the adhesive roller 36 to roll and apply adhesive.

The lower end of the slide rod 222 is fixedly connected to the rear of the upper end of the lifting plate 23.

[0032] The output end of cylinder 221 can drive the lifting plate 23 to descend as a whole, which allows the adhesive roller 36 to quickly contact the surface of the sanitary napkin, and allows the two pressure plates 27 to press the front and back of the sanitary napkin together. The slide rod 222 has a limiting function for the movement of the lifting plate 23.

[0033] like Figure 4 As shown, the opposing adjustment mechanism 24 includes an adjustable reverse double threaded rod 241. The front and rear ends of the reverse double threaded rod 241 are rotatably connected to the front and rear positions of the lower right part of the lifting plate 23. The front and rear positions of the bottom right parts of the two movable frames 25 are threadedly connected to the front and rear parts of the outer wall of the reverse double threaded rod 241.

[0034] Depending on the size of the sanitary napkin, rotating the reverse double-threaded rod 241 causes the two movable frames 25 to move in opposite directions via a threaded connection with the reverse double-threaded rod 241.

[0035] like Figure 4 As shown, a guide rod 242 is fixedly installed at the front and rear positions of the lower left part of the lifting plate 23, and the front and rear positions of the bottom left part of the two movable frames 25 are slidably connected to the front and rear parts of the outer wall of the guide rod 242.

[0036] The guide rod 242 has a limiting effect on the movement of the two movable frames 25.

[0037] like Figure 5As shown, the glue dispensing mechanism 32 includes a liquid tank 321, the lower end of which is fixedly installed on the upper end of the mounting frame 21, and a glue outlet pipe 322 is fixedly installed on the lower end of the liquid tank 321 and penetrates through the top of the lifting plate 23, and the glue outlet pipe 322 is connected with the liquid control tank 31.

[0038] The liquid tank 321 is used for storing glue, the glue flows into the liquid control tank through the glue outlet pipe 322, and the glue is generally pumped out by a water pump provided in the liquid tank 321, and the liquid control tank 31 can heat the glue to an appropriate temperature to improve the adhesion of the glue.

[0039] As shown, Figure 5 A valve 323 is fixedly installed on the inner cavity of the top of the glue outlet pipe 322.

[0040] The valve 323 is used for controlling the opening and closing of the glue outlet pipe 322 and the flow of the glue.

[0041] As shown, Figure 5 A sliding groove 38 is formed on the lower end of the liquid control tank 31, and the upper end of the moving plate 35 is slidably connected with the inner wall of the sliding groove 38.

[0042] The sliding groove 38 limits the movement of the moving plate 35.

[0043] The working principle of the utility model is as follows: according to the size of the sanitary napkin to be processed, the reverse double-threaded rod 241 is rotated, the two moving frames 25 are oppositely moved through the threaded connection with the reverse double-threaded rod 241, so that the two pressing plates 27 can cope with different batches of sanitary napkins, and the sanitary napkin is continuously transmitted to the lower side of the mounting frame 21 by the electric transmission belt 4, when the sanitary napkin is located directly below the glue roller 36, the electric transmission belt 4 is timely stopped, the output end of the air cylinder 221 can drive the lifting plate 23 to descend as a whole, so that the glue roller 36 can quickly contact the surface of the sanitary napkin, and the two pressing plates 27 can press the front and rear parts of the sanitary napkin, the liquid tank 321 is used for storing glue, the glue flows into the liquid control tank through the glue outlet pipe 322, the glue is generally pumped out by a water pump provided in the liquid tank 321, the liquid control tank 31 can heat the glue to an appropriate temperature to improve the adhesion of the glue, the glue is delivered to the surface of the glue roller 36 through the two glue delivery pipes 37, according to the range of the glue to be applied to the sanitary napkin, the motor 34 is started, the output end of the motor 34 can drive the screw rod 33 to rotate, the moving plate 35 can drive the glue roller 36 to roll and apply glue through the threaded connection with the screw rod 33.

[0044] After the glue application is completed, the glue roller 36 moves upwards, the two pressing plates 27 continue to press the surface of the sanitary napkin due to the elastic restoring force of the four spring guide shafts 28, so that the sanitary napkin can be prevented from separating from the electric transmission belt 4 due to the adhesion of the glue, and then the electric transmission belt 4 is continuously started to deliver the sanitary napkin with the applied glue.

[0045] The basic principle and main features of the present application and the advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
