Description

Technical Field

[0001] The utility model relates to a high-temperature shrink tube cutter assembly, belonging to the technical field of cutters. Background Art

[0002] Heat shrink tubing, also known as heat shrink tubing or heat shrink sleeves, is a specialized polyolefin-based heat shrink tubing. It's made from a high-quality, soft, cross-linked polyolefin outer layer and a hot-melt adhesive inner layer. The outer layer offers insulation, corrosion resistance, and wear resistance, while the inner layer has a low melting point, waterproof sealing, and high adhesion.

[0003] At present, some cutting mechanisms use an annular cutter head to cut the workpiece with a heat shrink tube, so as to remove the excess heat shrink tube on the workpiece. The annular cutter head is generally directly set on the tool holder. In order to facilitate the replacement of the tool holder, it is generally placed on the workpiece. However, during the cutting process, due to the uneven weight distribution between the tool holder and the rotating shaft, the annular cutter head is prone to deflection during rotation, resulting in irregular incisions and affecting the cutting effect. Summary of the Invention

[0004] The purpose of the utility model is to provide a high-temperature shrink tube cutter assembly, which can prevent the cutter head from swinging on the basis of facilitating the replacement of the cutter holder, thereby achieving a neat and beautiful incision and improving the cutting effect.

[0005] To achieve the above-mentioned object, the present invention adopts a technical solution: a high-temperature shrink tube cutter assembly, comprising: a base body, a mounting block having a bottom portion of the base body, a mounting hole extending through two side walls of the mounting block, and a stop ring provided on the inner wall of the mounting hole, thereby dividing the interior space of the mounting hole into a first mounting groove and a second mounting groove, and a bearing is installed in each of the first mounting groove and the second mounting groove;

[0006] A tool holder with an annular tool head is provided on one side of the mounting block. A connecting rod is provided on the side of the tool holder relative to the mounting block. The end of the connecting rod away from the tool holder can pass through two bearings and be connected to a fastener.

[0007] The further improved scheme in the above technical scheme is as follows:

[0008] 1. In the above solution, the axis of the mounting hole and the axis of the annular cutter head are arranged coaxially.

[0009] 2. In the above solution, the diameter of the annular cutter head is 1.5 to 3 times the diameter of the tool holder.

[0010] 3. In the above solution, the shape of the mounting block is an inverted L-shape.

[0011] 4. In the above solution, there is a gap between the stop ring and the connecting rod.

[0012] Due to the application of the above technical solution, the utility model has the following advantages compared with the prior art:

[0013] The utility model discloses a high-temperature shrink tube cutter assembly, wherein bearings are installed inside the first mounting groove and the second mounting groove, and a knife holder with an annular cutter head is provided on one side of the mounting block, and a connecting rod is provided on the rotation center of the knife holder on one side relative to the mounting block, and the end of the connecting rod away from the knife holder passes through the two bearings and is connected to the fastener. The knife holder can be quickly installed and disassembled by passing the connecting rod of the knife holder through the two bearings and being connected to the fastener. On the basis of facilitating the replacement of the knife holder, the position accuracy of the knife holder is also improved, and the knife head can be prevented from swinging, which is conducive to achieving a neat and beautiful incision and improving the cutting effect.

[0018] The present invention can be further understood through the specific embodiments given below, but they are not intended to limit the present invention.

[0019] Example 1: A high-temperature shrink tubing cutter assembly, comprising: a base 2, a mounting block 3 having a bottom portion thereof, a mounting hole 4 extending between two side walls of the mounting block 3, and a stop ring 6 disposed on the inner wall of the mounting hole 4, thereby dividing the interior space of the mounting hole 4 into a first mounting groove 51 and a second mounting groove 52. A bearing 7 is disposed within each of the first mounting groove 51 and the second mounting groove 52;

[0020] When in use, the tool holder with the annular cutter head can be quickly disassembled and assembled by passing the connecting rod of the tool holder through the two bearings in sequence and then connecting to the fastener.

[0021] A tool holder 8 with an annular tool head 1 is provided on one side of the mounting block 3 , and a connecting rod 9 is provided on the side of the tool holder 8 relative to the mounting block 3 , and the end of the connecting rod 9 away from the tool holder 8 can pass through two bearings 7 and be connected to the fastener 10 .

[0022] The connecting rod is limited by two bearings, which greatly improves the position accuracy of the rotation center of the tool holder, further avoids the situation where the annular cutter head swings during rotation, and is conducive to achieving neat and beautiful incisions.

[0023] The diameter of the annular cutter head 1 is 1.6 times the diameter of the cutter holder 8 .

[0024] The shape of the mounting block 3 is an inverted L-shape.

[0025] The circumferential outer wall of the connecting rod 9 at one end away from the tool holder 8 has a thread, and the fastener 10 is a nut.

[0026] There is a gap between the stop ring 6 and the connecting rod 9 .
