In order to ensure the shrinkage of the heat shrink tube, the sample of each roll of material needs to be taken for detection of the shrinkage. Before detection, the heat shrink tube needs to be marked manually, and then the size of the heat shrink tube after heat shrinkage is detected. In the process, there is a certain error in the marked size, and the labor intensity is large.

[0003] A device for marking heat shrink tubes by using laser technology is provided in Chinese patent application No. CN106275670A. The device focuses laser beams on the surface of the heat shrink tube through the upper laser and the lower laser through the lens to form a plurality of fine and high-energy-density light spots.

[0045] In order to limit the front pressing connecting plate 271 and the rear pressing plate 261 in the clamping assembly 2, the clamping assembly 2 further comprises a limiting plate 232, as shown in Figure 1As shown, the adjusting assembly 3 comprises a bottom plate 38, a right and left threaded rod assembly, a right threaded nut 35, and a left threaded nut 36. The bottom plate 38 is provided with a guide groove. The right and left threaded rod assembly is connected with the bottom plate 38. The right threaded nut 35 is arranged on the right thread of the right and left threaded rod assembly. The left threaded nut 36 is arranged on the left thread of the right and left threaded rod assembly. The right threaded nut 35 and the left threaded nut 36 are moved along the guide groove with the rotation of the right and left threaded rod assembly. For example, two follow-up bearings are respectively arranged on the right threaded nut 35 and the left threaded nut 36.

[0046] In use, the front pressing connecting plate 271 is moved to the right threaded nut 35 by the driving member B281. The rear pressing plate 261 is moved to the left threaded nut 36 by the driving member C282. The heat shrink tube 6 is arranged between the front pressing plate 2914 and the rear pressing plate 261 for fitting. If the distance between the heat shrink tube 6 and the front pressing plate 2914 and the rear pressing plate 261 is not matched, the positions of the right threaded nut 35 and the left threaded nut 36 are adjusted by rotating the right and left threaded rod assembly, so as to adjust the distance between the front pressing plate 2914 and the rear pressing plate 261. Until the two sides of the heat shrink tube 6 are respectively attached to the front pressing plate 2914 and the rear pressing plate 261, the heat shrink tube 6 is positioned and clamped.

[0047] As shown in the drawings, Figure 1 The right and left threaded rod assembly comprises a right and left threaded rod 34 and at least two bearing seats 33. The bearing seats 33 are arranged on the bottom plate 38. The two bearing seats 33 are respectively arranged at the two ends of the right and left threaded rod 34. The right and left threaded rod 34 is connected with the bottom plate 38 through the bearing seats 33.

[0048] In order to facilitate the rotation of the right and left threaded rod 34, in a specific embodiment, the adjusting assembly 3 further comprises a hand wheel 31 and a clamping seat 32. The chuck of the clamping seat 32 is connected with the right and left threaded rod 34. The hand wheel 31 is connected with the right and left threaded rod 34. The right threaded nut 35 and the left threaded nut 36 are moved by rotating the hand wheel 31. When the positions of the right threaded nut 35 and the left threaded nut 36 are adjusted, the clamping seat 32 is locked to prevent the right and left threaded rod 34 from moving due to vibration and other reasons during work.

[0049] In order to buffer the front pressing connecting plate 271 and the rear pressing plate 261 when the front pressing connecting plate 271 is in contact with the right threaded nut 35 and the rear pressing plate 261 is in contact with the left threaded nut 36, in a specific embodiment, the right threaded nut 35 and the left threaded nut 36 are respectively provided with an oil buffer 37.

The two ends of the front pressing plate 2914 are respectively arranged on the sliding blocks of the two linear guide rails 2911 through the two cushion blocks 2913, and the two linear guide rails 2911 are respectively arranged at the two ends of the front pressing connecting plate 271. The two side follow-up bearings 2912 are respectively arranged on the two cushion blocks 2913, and the side follow-up bearings 2912 are respectively arranged in the sliding grooves of the left sliding groove plate 22 and the right sliding groove plate 21. As shown in Figure 2 , the left sliding groove 221 and the right sliding groove 211 are both flat at the rear end and gradually inclined downward at the front end. The left sliding groove plate 22 and the right sliding groove plate 21 are arranged between the cutter bottom plate 15 and the bottom plate 38. By arranging the up-down movable assembly 291, when the driving part B281 moves the front pressing connecting plate 271 forward, the front pressing plate 2914 can be moved forward and downward, thereby facilitating the placement of the heat shrink tube 6.

[0051] In order to ensure that the heat shrink tube 6 is flat when cutting, as shown in Figure 5 , it also includes a pressing assembly 4, which includes a driving part D41, a push plate 42, and a pressing plate 43. The driving part D41 is connected with the top plate 16 and arranged below the top plate 16. The driving part D41 is signal connected with the controller 54. The driving part D41 is connected with the push plate 42, which moves up and down under the action of the driving part D41. The pressing plate 43 is connected with the push plate 42, and the pressing plate 43 is located between the first cutter 111 and the second cutter 112. After placing the heat shrink tube 6 on the cutter bottom plate 15, the driving part D41 drives the pressing plate 43 to the upper end of the heat shrink tube 6, and the heat shrink tube 6 is clamped between the pressing plate 43 and the cutter bottom plate 15, which can flatten the heat shrink tube 6.

[0052] As shown in Figure 4As shown, the cutter assembly 1 further comprises two optical shafts 18, a second linear bearing 17, a first cutter holder, a second cutter holder, a blade insert A 151, and a blade insert B 152. The two optical shafts 18 are respectively arranged on both sides of the driving member A 19, and the optical shafts pass through the top plate 16 and are connected with the cutter top plate 110 at the lower end.

The second cutter holder is arranged on the other side of the cutter top plate 110, and the cutter top plate 110 is connected with the second cutter 112 through the second cutter holder. The blade insert A 151 is arranged on the cutter bottom plate 15 and corresponds to the position of the first cutter 111. The blade insert B 152 is arranged on the cutter bottom plate 15 and corresponds to the position of the second cutter 112.

[0053] When the driving member A 19 is pressed down, the cutter top plate 110 is driven to move downward. The two optical shafts 18 arranged on both sides of the driving member A 19 move downward with the cutter top plate 110, thereby ensuring that the positions of the first cutter 111 and the second cutter 112 do not change when the first cutter 111 and the second cutter 112 move downward. If the positions of the first cutter 111 and the second cutter 112 swing, the clearances between the first cutter 111 and the blade insert A 151 and between the second cutter 112 and the blade insert B 152 change. When the clearances increase, the heat shrink tube 6 may not be cut. When the clearances decrease, the first cutter 111 and the second cutter 112 may collide. Therefore, by arranging the optical shaft 18 and the second linear bearing 17, the first cutter 111 and the second cutter 112 can be prevented from tilting when moving downward.

[0054] In order to prevent the first cutter 111 and the second cutter 112 from being accidentally touched, the cutter assembly 1 further comprises a right side plate 11, a left side plate 12, a rear guard plate 13, and a front guard plate assembly 14. The upper ends of the right side plate 11, the left side plate 12, the rear guard plate 13, and the front guard plate assembly 14 are connected with the top plate 16. The lower ends of the right side plate 11, the left side plate 12, and the rear guard plate 13 are connected with the cutter bottom plate 15. The lower end of the front guard plate assembly 14 has a certain spacing from the cutter bottom plate 15, so that the heat shrink tube 6 can be placed through the spacing.

[0055] In a specific embodiment, the driving member A 19, the driving member B 281, the driving member C 282, and the driving member D 41 can all be air cylinders.

Official working stage: stack multiple heat shrink tubes 6 at the positions of the first cutter 111 and the second cutter 112, press the start button A 511 and the start button B 512 with both hands, the controller 54 controls the driving part B 281 and the driving part C to act simultaneously, the driving part C 282 pushes the rear pressing plate 261 to move forward along the first guide rod 241 and the second guide rod 242 to the clamping position, and the driving part B 281 pushes the front pressing connecting plate 271 to move backward to the clamping position, and the front pressing plate 2914 on the front pressing connecting plate 271 moves along the sliding groove track on the left sliding groove plate 22 and the right sliding groove plate 21 during the contraction process, rises and moves backward to the clamping position; the front pressing plate 2914 and the rear pressing plate 261 clamp the heat shrink tube 6 to the middle position of the cutter. Then, the driving part D 41 drives the lower pressing plate 43 to move downward to press the heat shrink tube 6. Next, the driving part A 19 pushes the cutter top plate 110 to move downward, thereby driving the first cutter 111 and the second cutter 112 to move vertically downward, the second cutter 112 cuts off one end of the heat shrink tube 6 to form a full cutting position 61 of the heat shrink tube, and the first cutter 111 cuts half of the heat shrink tube 6 in the middle to form a half cutting mark position 62 of the heat shrink tube; finally, the driving part A 19 and the driving part D 41 are reset in sequence and drive the related components to reset, and the driving part B 281 and the driving part C 282 simultaneously drive the front pressing connecting plate 271 and the rear pressing plate 261 to reset, and the heat shrink tube 6 is taken out.
