Description

Technical Field

[0001] This utility model relates to the technical field of heat shrink tubing cutting equipment, specifically an automatic heat shrink tubing cutting device. Background Technology

[0002] Heat shrink tubing, due to its high-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion resistance, is widely used for insulation protection of various wire harnesses, solder joints, and inductors, as well as for rust and corrosion prevention of metal tubes and rods. Therefore, heat shrink tubing needs to be cut to different lengths in large quantities. To meet production needs, automatic heat shrink tubing cutting equipment is commonly used. This equipment can automatically feed and cut heat shrink tubing coils according to a set length. For example, a heat shrink tubing cutting device disclosed in patent document CN 216760004 U uses a corresponding PLC to control the operating speed of its drive motor, cutting cylinder, and pressure roller drive motor. By adjusting the corresponding speed, the length of the tubing cut under the movement of the cutting cylinder is adjusted, achieving automated cutting. However, the clamping adjustment of this cutting device is not convenient. Utility Model Content

[0003] In view of this, this utility model provides an automatic heat shrink tubing cutting device to address the shortcomings of the existing technology.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an automatic heat shrink tubing cutting device, including a machine base, and a heat shrink tubing coil rack, a guide component, a drive component, a clamping adjustment component, and a cutting component disposed on the machine base. The drive component includes side plates, a rotating roller, and a drive motor. Two side plates are arranged parallel to each other on the machine base. The two ends of the rotating roller are respectively mounted on the two side plates through bearings. The drive motor is connected to one end of the rotating roller for transmission. The clamping adjustment component includes a clamping roller, a gate-shaped handle, and an adjusting rod. The two sides of the gate-shaped handle are respectively hinged to the two side plates. The lower ends of both sides of the gate-shaped handle are connected to the machine base through springs. The two ends of the clamping roller are respectively rotatably connected to the two sides of the gate-shaped handle. The two side shafts of the clamping roller pass through the two sides of the gate-shaped handle and enter the cavities of the two side plates. An opening is provided at the top of the side plate. The lower end of the adjusting rod is inserted into the opening and is movably connected to the shaft. A nut is threadedly connected to the upper end of the adjusting rod.

[0005] Furthermore, the guiding component includes two guide grooves, which gradually narrow along the advancing direction of the heat shrink tubing, and pressure plates are provided at the ends of the two guide grooves.

[0006] Furthermore, the cutting component includes a telescopic cylinder, a blade holder, and a blade head. The telescopic end of the telescopic cylinder faces downward, and the blade holder is provided at the end of the telescopic cylinder. The blade head is installed on the lower side of the blade holder.

[0007] Furthermore, a ring is provided at the lower end of the adjusting rod, and the ring is sleeved on the shaft.

[0008] Furthermore, an arc-shaped hole is provided on the inner side of the side plate at the position corresponding to the movement trajectory of the shaft.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model relates to an automatic heat shrink tubing cutting device. Heat shrink tubing on a heat shrink tubing reel is guided by a guide component to a drive component and a clamping adjustment component. During clamping, one end of the gate-shaped handle is pressed to separate the clamping roller from the drive roller, facilitating the passage of the heat shrink tubing. Releasing the gate-shaped handle allows the handle to press the heat shrink tubing between the clamping roller and the drive roller under the action of a spring. Then, the nut on the adjusting rod is turned to slightly raise the adjusting rod, increasing the distance between the clamping roller and the drive roller to prevent damage from squeezing the heat shrink tubing. Simultaneously, the heat shrink tubing can move forward under the action of the drive roller, and the cutting component cuts the heat shrink tubing at a fixed distance.

[0010] In addition, the guide component uses two guide grooves, which can automatically cut two heat shrink tubings at the same time, improving the efficiency of the automatic heat shrink tubing cutting equipment. Attached Figure Description
