DETAILED DESCRIPTION

[0016] Please refer to Figs. 1-2 In the utility model embodiment, a positioning mechanism for rubber tube cutting includes a workbench 1, the lower surface of the workbench 1 is fixedly connected with a support leg 2, the upper surface of the workbench 1 is fixedly connected with an air cylinder 9, the driving end of the air cylinder 9 is fixedly connected with a lower fixing part 10, the upper surface of the lower fixing part 10 is hingedly connected with an upper fixing part 11, the inside of the lower fixing part 10 and the upper fixing part 11 is provided with a placement cavity 12, the length of the placement cavity 12 is less than the length of the rubber tube, and the two sides of the placement cavity 12 are provided with cutting mechanisms.

[0017] Preferably, the cutting mechanism includes a support 5, the inside of the support 5 is rotatably connected with a shaft 6, one end of the shaft 6 towards the lower fixing part 10 is fixedly connected with a turntable 7, the surface of the turntable 7 close to the lower fixing part 10 is fixedly connected with a blade 8, and the blade 8 is parallelly arranged with the surface of the turntable 7 close to the lower fixing part 10.

[0018] Preferably, the lower surface of the workbench 1 is fixedly installed with a double-shaft motor 3, and the two driving ends of the double-shaft motor 3 are respectively and surface of the two shafts 6 are sleeved with a belt 4.

[0019] Preferably, the placement cavity 12 has a corrugated groove inside that matches the surface of the waist of the rubber tube, so that the corrugated part of the surface of the rubber tube corresponds to the corrugated groove on the surface of the placement cavity 12.

[0020] Preferably, the lower fixing member 10 is fixedly connected to a locking block 13 on the side away from the hinge, and every two locking blocks 13 form a group. The upper fixing member 11 is fixedly connected to a fixing block 14 on the surface away from the hinge. The fixing block 14 is rotatably connected to a connecting rod 15. The surface of the connecting rod 15 is sleeved with a threaded rod 16. The surface of the threaded rod 16 is threadedly connected to a butterfly knob 17.

[0021] Preferably, the distance between the two locking blocks 13 in each group is greater than the diameter of the threaded rod 16 and less than the outer diameter of the nut part of the butterfly knob 17.

[0022] The working principle of this utility model is as follows: When cutting the rubber tube, the rubber tube needs to be fixed first. The rubber tube is placed in the placement cavity 12 on the surface of the lower fixing member 10, so that the corrugated part of the rubber tube surface corresponds to the corrugated groove opened on the surface of the placement cavity 12. Then, the upper fixing member 11 is closed, and the threaded rod 16 is rotated so that the butterfly knob 17 is rotated to the lower side of the locking block 13. Then, the butterfly knob 17 is rotated, and the nut part of the butterfly knob 17 abuts against the lower surface of the locking block 13, thereby fixing the rubber tube inside the placement cavity 12. Then, the cylinder 9 is opened, so that... The lower fixing member 10 and the upper fixing member 11 move down, and then the dual-axis motor 3 is turned on. The belt 4 drives the rotating shaft 6 to rotate, which in turn rotates the turntable 7 and the blade 8. The blade 8 cuts off the end of the rubber tube. Then the dual-axis motor 3 is turned off, and the cylinder 9 is reset. The butterfly knob 17 is rotated in the opposite direction to open the upper fixing member 11. The next rubber tube to be processed is placed into the placement cavity 12 on the surface of the lower fixing member 10. The above process is repeated. When processing both ends of the rubber tube, the device processes them simultaneously, which improves efficiency compared to processing both ends separately.
