The heat shrink box 6 is formed by fitting existing heat shrink tubing onto a molding die, shrinking it under heat, and then shaping it outside the molding die to form a series of spaced heat shrink boxes. The heat shrink box series is then cut. In use, the position of the heat shrink box series is measured on the side of the measuring support mechanism and marked with a marker. After marking the cutting point, the heat shrink box assembly is placed on the measuring support mechanism. At the same time, the marking between the first and second heat shrink boxes is located on the cutting mechanism. The crimping mechanism presses down on the part of the heat shrink box assembly located on the measuring support mechanism to fix its position. Then, the cutting mechanism cuts the marking between the first and second heat shrink boxes. After the first heat shrink box is cut, it is guided by the material guiding mechanism to the external collection box to complete the cutting. After that, the crimping mechanism is reset, and the heat shrink box assembly is moved until the marking between the second and third heat shrink boxes is located on the cutting mechanism. The previous crimping and cutting steps are repeated to complete the cutting.

[0021] In this embodiment, in order to achieve cutting, the cutting mechanism includes an upper blade plate 7 and a lower blade plate 8. The blade edge of the upper blade plate is at the bottom, and the blade edge of the lower blade plate is at the top. The lower blade plate is vertically fixed to the support frame in the front-to-back direction. The rear end of the upper blade plate is hinged to the rear end of the lower blade plate. A cutting drive mechanism 9 is mounted on the support frame to drive the upper blade plate to open and close up and down. That is, the cutting drive mechanism drives the upper blade plate to rotate around the hinge axis to realize the opening and closing between the upper blade plate and the lower blade plate, thereby realizing cutting.

[0022] In this embodiment, in order to realize the cutting drive mechanism driving the upper blade plate to move, the cutting drive mechanism includes a vertically arranged cutting drive cylinder 10, and a mounting frame 11 is provided on the rear side of the support frame. The cutting drive cylinder is vertically mounted on the mounting frame and is mounted above the upper blade plate. The upper blade plate has guide pressure holes 12 along its length direction. The telescopic end of the cutting drive cylinder faces downward and slides on the guide pressure holes. More specifically, the telescopic end of the cutting drive cylinder has a clearance groove 13. The upper blade plate with the guide pressure holes is located between the clearance grooves. A sliding shaft 14 is horizontally placed in the clearance groove and slides in the guide pressure holes. In use, the telescopic end of the cutting drive cylinder extends and retracts, thereby driving the sliding shaft to slide in the guide pressure holes, realizing the opening and closing between the upper blade plate and the lower blade plate.

[0023] In this embodiment, to provide an installation foundation for the cutting mechanism, material guiding mechanism, measuring support mechanism, and pressing mechanism, the support frame includes a support platform 15. The support platform is a frame structure with support columns at its four corners. The mounting frame is located on the rear side of the support platform. Inside the support platform, two support crossbars 16 are arranged from front to back. The lower blade is fixed to the two support crossbars. L-shaped support plates 17 are arranged on the support crossbars corresponding to the left and right sides of the lower blade. The horizontal part of the L-shaped support plate is at the bottom, and the vertical part is at the top. The vertical part of the two L-shaped support plates... The straight sections are respectively attached to both sides of the lower blade plate, which is clamped between the vertical sections of two L-shaped support plates and locked with bolts. The horizontal section of the L-shaped support plate is fixed to the support crossbar, that is, the lower blade plate is fixed by the L-shaped support plate. The lower blade plate is set between the vertical sections of two L-shaped support plates on the same support crossbar. Both vertical sections of the two L-shaped support plates on the same support crossbar are provided with through holes, and the lower blade plate is also provided with corresponding through holes. The corresponding through holes on the two L-shaped support plates and the lower blade plate are connected by bolts and nuts to fix the lower blade plate.

[0024] In this embodiment, in order to guide the material after cutting, the material guiding mechanism includes an inclined guide plate 18, which is disposed below the cutting mechanism. The guide plate is inclined towards the left and right sides of the support frame. Baffles 19 are symmetrically arranged on the left and right sides of the guide plate in the inclined direction. A horizontal connecting plate 20 is provided at the inclined upper end of the guide plate. The horizontal connecting plate is fixed to two support crossbars. Since the support platform is a frame structure, the area between the two support crossbars is divided into two areas by the lower blade. Material is fed into one area from the top, and the cut heat shrink box is sent out from the bottom of the other area. Specifically, after the cutting structure cuts, the cut box will fall onto the guide plate. Under the action of gravity, the cut box slides down the guide plate and is sent into the external collection box.

[0025] In this embodiment, to achieve measurement and marking of the heat shrink box assembly, the measurement support mechanism includes a support plate 21, which is mounted on the support platform on the side away from the guide plate. The support plate has graduations along its length. To achieve crimping of the heat shrink box assembly, the crimping mechanism includes a crimping cylinder 23 mounted above the support plate. A crimping bracket 24 is mounted on the side of the support platform corresponding to the crimping cylinder. The crimping cylinder is fixed to the crimping bracket, with its extension end pointing downwards. An upper clamping assembly 25 is mounted below the extension end of the crimping cylinder. The support plate... The upper clamping assembly is provided with a lower clamping assembly 26. More specifically, the lower clamping assembly includes lower clamping plates 27 symmetrically arranged front and rear. The lower clamping plates are L-shaped, with the horizontal part at the bottom and the vertical part at the top. The horizontal part of the lower clamping plate slides back and forth on a support plate. At least two guide holes 28 are arranged parallel to each other on the horizontal part of the lower clamping plate. Guide pins 29 are provided on the support plate corresponding to the guide holes. The upper clamping assembly includes a base plate 30, which is horizontally fixed under the pressing cylinder. Upper clamping plates 31 are symmetrically arranged front and rear under the base plate. The clamping plate is L-shaped, with the horizontal part of the upper clamping plate on top and the vertical part on the bottom. The horizontal part of the upper clamping plate slides back and forth under the base plate. At least two guide holes are arranged parallel to each other on the horizontal part of the upper clamping plate. Guide pins are arranged on the base plate corresponding to the guide holes. That is, the lower clamping plates are arranged on both sides of the heat shrink box assembly along the length direction, and the upper clamping plates are arranged corresponding to the lower clamping plates. In use, by loosening the guide pins, the horizontal parts of the lower and upper clamping plates can slide on the support plate or base plate until the vertical parts of the two lower clamping plates and the two upper clamping plates correspond to the heat shrink box assembly. Tighten the guide pins on both sides of the heat shrink box assembly until the pin heads abut against the horizontal parts of the lower and upper pressure plates, thus fixing the positions of the upper and lower pressure plates. This facilitates position adjustment for heat shrink boxes of different sizes, making the overall equipment more adaptable. In use, the pressing assembly is first moved by the pressing cylinder to fix the heat shrink box assembly. Then, the cutting cylinder moves to achieve cutting. At the same time, the horizontal part of the lower pressure plate and the support plate, and the horizontal part of the upper pressure plate and the base plate can be connected by a slider or groove for easy sliding.
