[0022] refer to Figure 1-9 The present invention proposes a heat shrink tube trimming device, the heat shrink tube is composed of a copper bus 1 and a heat shrink layer 2 tightly wrapped outside the copper bus 1. The device cuts a specific slit on the heat shrink layer 2 of the heat shrink tube through the coordinated work of four cutting devices to meet the needs of subsequent processing or use.

[0023] First cutting device: After the heat shrink tube is firmly fixed, this device is responsible for cutting a first slit 3 extending straight in the vertical direction and completely penetrating the heat shrink layer 2 from top to bottom on the heat shrink layer 2 on the left side of the copper busbar 1. The slit reaches the outer wall of the copper busbar 1, laying the foundation for the subsequent processing of the heat shrink layer;

[0024] The second cutting device: corresponding to the first cutting device, cuts a second slit 4 extending in the vertical direction and penetrating the heat shrinkable layer 2 up and down on the heat shrinkable layer 2 on the right side of the copper busbar 1. Similarly, the second slit 4 also accurately reaches the outer wall of the copper busbar 1, ensuring the symmetry and consistency of the slits on both sides;

[0025] The third cutting device is used to cut a third slit 5 extending in the horizontal direction above the copper bar 1 on the heat shrinkable layer 2, and the slit connects the first slit 3 and the second slit 4. Through the setting of the horizontal slit, the part of the heat shrinkable layer 2 above the copper bar 1 is connected with the vertical slits on both sides, which is convenient for the subsequent separation or processing of the heat shrinkable layer;

[0026] Fourth cutting device: a fourth slit 6 extending in the horizontal direction and connecting the first slit 3 and the second slit 4 is cut below the copper bar 1 on the heat shrinkable layer 2. The fourth slit 6 cooperates with the third slit 5 to connect the part of the heat shrinkable layer 2 below the copper bar 1 with the vertical slits on both sides, thereby completely forming a slit combination around the copper bar 1 on the heat shrinkable layer 2, which is convenient for the operation of removing the heat shrinkable layer as a whole or in part;

[0027] Frame 7: As the basic supporting structure of the entire equipment, it provides a stable installation platform for other components, can withstand various forces generated during the operation of the equipment, and ensure the accuracy of the cutting operation;

[0028] The first driving mechanism 8: a cylinder is selected as a driving element and is installed on the frame 7. Its main function is to drive the first seat body 10 connected thereto to move along the first direction on the frame 7. The cylinder has the advantages of fast response speed and stable thrust, and can control the moving position and speed of the first seat body 10. By adjusting the air intake and pressure of the cylinder, the first seat body 10 can be controlled at different speeds and displacements to meet the cutting requirements of heat shrink tubes of different specifications;

[0029] The second driving mechanism 9: adopts a vibration motor, which is installed on the first base body 10. The vibration motor can generate high-frequency vibration to drive the second base body 11 to move on the first base body 10 along a second direction perpendicular to the first direction, so that the second base body 11 can achieve rapid reciprocating movement within a short distance, thereby meeting the requirements of the third and fourth cutting devices to cut horizontal slits on the heat shrinkable layer 2;

[0030] The first seat body 10 is movably mounted on the frame 7. As an intermediate component connecting the first driving mechanism 8 and the second seat body 11, it not only bears the driving force of the first driving mechanism 8, but also provides a mounting base for the second driving mechanism 9 and the second seat body 11. The surface of the first seat body 10 is flat to ensure the stability of the second seat body 11 moving thereon;

[0031] The second seat body 11 is movably mounted on the first seat body 10 and moves along the second direction under the action of the second driving mechanism 9. A limited position tool 12 is installed on the second seat body 11 to fix the heat shrink tube, and can ensure the matching accuracy with the first seat body 10 and the stability of the heat shrink tube fixation, so as to ensure that the heat shrink tube will not be displaced during the cutting process, thereby affecting the cutting quality;

[0032] The position limiting fixture 12 is installed on the second seat body 11 and adopts a special fixture design, which can be flexibly adjusted according to the size of the heat shrink tube. It uses multiple cylinders to firmly clamp the heat shrink tube from different directions to ensure that the heat shrink tube can maintain a stable position during the cutting process when it is arranged horizontally;

[0033] First cutting device:

[0034] The third driving mechanism 13: uses a cylinder as a power source, is installed on the frame 7, and can accurately control the extension and retraction of its piston rod, thereby realizing the upward or downward driving of the first tool assembly 14 to meet the cutting requirements of heat shrink tubes of different materials and wall thicknesses;

[0035] The first cutter assembly 14 is movably mounted on the frame 7 and connected to the piston rod of the third driving mechanism 13. The first cutter assembly 14 uses a special sharp blade. The shape and size of the blade are designed according to the cutting requirements of the heat shrink tube to ensure that a neat first slit 3 can be cut on the heat shrink layer 2.

[0036] Second cutting device:

[0037] The fourth driving mechanism 15 is also a cylinder, which is installed on the frame 7 and drives the second tool assembly 16 to move upward or downward.

[0038] The second tool assembly 16 is movably mounted on the frame 7 and connected to the piston rod of the fourth driving mechanism 15. The blade of the second tool assembly 16 is designed to be consistent with the blade of the first tool assembly 14 to ensure that the second slit 4 cut on the right side of the heat shrinkable layer 2 has the same quality and accuracy as the first slit 3.

[0039] The third cutting device:

[0040] The fifth driving mechanism 17 uses a cylinder as a driving element, connects to the third cutter assembly 18 and controls its upward or downward movement, ensures that the third cutter assembly 18 can be lowered to a specified position, and makes the blade cut the heat shrinkable layer 2 and abut against the upper end surface of the copper busbar 1;

[0041] The third cutter assembly 18 is movably mounted on the frame 7 and can smoothly cut the third slit 5 on the heat shrinkable layer 2. When the fifth driving mechanism 17 drives the third cutter assembly 18 to move downward to a certain position, and the second driving mechanism 9 drives the second seat 11 to continuously move back and forth along the second direction, the blade of the third cutter assembly 18 can move along with the movement of the heat shrinkable tube to cut the third horizontal slit 5 on the heat shrinkable layer 2.

[0042] Fourth cutting device:

[0043] The sixth driving mechanism 19: adopts a cylinder, connected to the fourth tool assembly 20 and drives it upward or downward. The sixth driving mechanism 19 and the fifth driving mechanism 17 realize synchronous action through a synchronous control circuit, ensuring that when the fifth driving mechanism 17 drives the third tool assembly 18 downward to make the blade abut against the upper end surface of the copper busbar 1, the sixth driving mechanism 19 can synchronously drive the fourth tool assembly 20 upward to make the blade cut the heat shrink layer 2 and abut against the lower end surface of the copper busbar 1;

[0044] The fourth tool assembly 20 is movably mounted on the frame 7. Its structure and performance are similar to those of the third tool assembly 18. The blade also has good cutting performance. When the second driving mechanism 9 drives the second seat 11 to continuously reciprocate along the second direction, the blade of the fourth tool assembly 20 simultaneously cuts a fourth slit 6 on the heat shrinkable layer 2, and cooperates with the third slit 5 to complete the task of cutting the heat shrinkable layer 2.

[0045] In summary, this heat shrink tube trimming equipment can efficiently and accurately trim the heat shrink layer of the heat shrink tube through the precise coordination and coordinated work of various components, meeting the processing requirements of heat shrink tubes of different specifications and materials.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
