Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Refer to Figure 1-Figure 5, An embodiment provided by the present utility model: A trimming device for processing schoolbag straps, including a base 1, a second rotating shaft 21, and a rotating shaft 27. A support column 2, a support frame 3, and a U-shaped column 4 are fixedly arranged on the base 1. A groove 5 and a chute 6 are fixedly arranged at the top of the U-shaped column 4. A first motor 7 is arranged in the groove 5. The output end of the first motor 7 is fixedly connected with a threaded rod 8. The threaded rod 8 is located inside the chute 6. A first slider 9 and a second slider 10 are threadedly connected to the threaded rod 8. The threads of the first slider 9 and the second slider 10 are arranged in the opposite direction. A cylinder 11 is fixedly connected below the first slider 9 and the second slider 10. A fixed block 12 is installed at the output end of the cylinder 11. A circular groove 13 and a circular hole 14 are arranged on the fixed block 12. By providing a trimming mechanism, the schoolbag strap is placed below the trimming mechanism. The first motor 7 drives the threaded rod 8 to rotate, thereby driving the first slider 9 and the second slider 10 to move inwards or outwards, and then driving the cylinder 11 to move inwards or outwards. The cylinder 11 drives the blade 26 on the fixed block 12 to move to the position where cutting is required. By adjusting the distance between the blades 26, the cutting of schoolbag straps with different widths can be adapted.

[0030] A second motor 16 is fixedly arranged at the top of the support column 2. The output end of the second motor 16 is fixedly connected with a first rotating shaft 17. A first belt pulley 18 is fixedly connected to the first rotating shaft 17. A second belt pulley 20 is fixedly connected to the second rotating shaft 21. A conveyor belt 19 is installed between the first belt pulley 18 and the second belt pulley 20. The first rotating shaft 17 passes through and is rotatably connected to the support frame 3. The second rotating shaft 21 passes through and is rotatably connected to the support frame 3. The rotating shaft 27 passes through and is rotatably connected to the support frame 3. A fourth belt pulley 23 and a rotating cylinder 25 are fixedly installed on the rotating shaft 27. A third belt pulley 22 is fixedly installed on the second rotating shaft 21. A first belt 24 is installed between the third belt pulley 22 and the fourth belt pulley 23. The third belt pulley 22 and the fourth belt pulley 23 are located outside the support frame 3. The rotating cylinder 25 is located inside the support frame 3. The rotating cylinder 25 is arranged on the second belt pulley 20. A heater is installed on the outer wall of the rotating cylinder 25. A blade 26 is installed in the circular groove 13, and a fixed column 15 is installed on the circular groove 13. The cylinder 11, the fixed block 12, the circular groove 13, the circular hole 14, the fixed column 15, and the blade 26 are all provided in two groups. The conveyor belt 19 has adhesiveness. By ironing the schoolbag strap, deformation of the schoolbag strap caused by the force of the blade 26 can be prevented.

[0031] Working principle: First, the operator places the shoulder strap of the school bag on the conveyor belt 19, and starts the motor 17. The output end of the motor 17 drives the threaded rod 8 to rotate, and then drives the slider 19 and the slider 2 10 to move to the required position, thereby driving the cylinder 11 to move to the required position, and then drives the blade 26 on the fixed block 12 to move to the required position, and then starts the cylinder 11. The output end of the cylinder 11 drives the fixed block 12 to move downward, and then drives the blade 26 on the fixed block 12 to move downward to the required cutting position, and the width of the shoulder strap of the school bag is cut by adjusting the spacing of the blades 26. Then, the motor 2 16 is started, and the output end of the motor 2 16 drives the fixed block 12 to move downward. The movable shaft 17 rotates, and the shaft 17 drives the pulley 18 and the pulley 2 20 to rotate through the conveyor belt 19, thereby moving the shoulder strap of the school bag to the position where the cutting is required. At the same time, the pulley 20 drives the shaft 21 to rotate, and then drives the pulley 3 22 on the shaft 21 to rotate. The pulley 3 22 drives the pulley 4 23 to rotate through the belt 24, thereby driving the rotating shaft 27 on the pulley 4 23 to rotate. The rotating shaft 27 drives the rotating drum 25 to rotate, which not only has a pressing effect on the shoulder straps of the school bag, but also starts the heater on the rotating drum 25 to iron the shoulder straps. By ironing the shoulder straps of the school bag, the deformation of the shoulder straps of the school bag due to the force of the blade 26 can be prevented.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
