[0033] During operation, in order to dispensing TPU material, the adjusting motor 31 is started, driving the adjusting screw 32 to rotate. The rotation of the adjusting screw 32 causes the adjusting block 34 to move linearly along the second positioning rod 33, thereby adjusting the position of the adjusting block 34 on the dispensing frame 29. By adjusting the position of the adjusting block 34, the dispensing gun 37 is moved to the designated position.

Finally, the dispensing gun 37 performs the dispensing operation.
[0034] Working principle: In order to fix the TPU material, the TPU material is first placed between the work racks 7, and then the adjusting handle 43 is turned to rotate the bidirectional lead screw 9, so that the two fixing plates 10 move towards or away from each other along the first positioning rod 8, thereby realizing the adjustment of the spacing between the fixing plates 10, which is used to fix TPU materials of different widths.
[0035] In order to transfer TPU material, the drive motor 6 is started, which drives the first drive screw 3 to rotate, causing the drive slider 4 to move linearly along the drive groove 2. The two drive sliders 4 are equipped with work frames 7, so the movement of the drive sliders 4 will drive the work frames 7 to move on the base 1. By adjusting the position of the work frames 7, the TPU material can be moved to adapt to different dispensing requirements.
[0036] To pre-clean the surface of the TPU material, the cleaning motor 18 is started, driving the pulley 19 at its output end to rotate. This drives the pulley 19 at the top of the cleaning roller 16 to rotate via the transmission belt 20, thereby causing the cleaning roller 16 to rotate and clean the surface of the TPU material using a brush. At the same time, the vacuum motor 24 is started, driving the vacuum fan 23 to rotate and generate suction. Dust and impurities near the dust collection hood 28 are sucked into the cleaning cylinder 21 through the vacuum pipe 25. The filter plate 22 filters the sucked-in air, and the dust and impurities are intercepted on one side of the filter plate 22. The cleaning cylinder 21 has a slag discharge port between the filter plate 22 and the vacuum pipe 25, as well as behind the filter plate 22. The slag discharge port is connected to the dust collection box 26, which has a slag discharge valve 27. When the dust accumulates to a certain level, the slag discharge valve 27 can be opened to clean the dust collection box 26.
[0037] To apply TPU material, the adjusting motor 31 is started, driving the adjusting screw 32 to rotate. The rotation of the adjusting screw 32 causes the adjusting block 34 to move linearly along the second positioning rod 33, thereby adjusting the position of the adjusting block 34 on the dispensing frame 29. By adjusting the position of the adjusting block 34, the dispensing gun 37 is moved to the designated position. The adjusting cylinder 35 is started to further fine-tune the height of the glue collection box 36 and the dispensing gun 37, so that the dispensing gun 37 reaches the appropriate dispensing position. The delivery pump 41 draws glue from the glue storage tank 40 through the glue extraction pipe, and then delivers the glue to the glue collection box 36 through the glue delivery pipe 42. Finally, the dispensing gun 37 performs the dispensing operation.
