Description

Technical Field

[0001] This utility model belongs to the field of heat shrink tubing cutting technology, specifically relating to a heat shrink tubing fixed-length cutting machine. Background Technology

[0002] Heat shrink tubing typically features low-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion protection. It's used to prevent the formation of copper oxide (verdigris) on individual wires in a wire harness over time, which can lead to poor conductivity and breakage; and to prevent short circuits caused by wires touching each other. Heat shrink tubing is generally used for protection and insulation of the wire harness.

[0003] Heat shrink tubing is generally quite long after production. When using it, workers need to use scissors to cut it to the required length. However, it is difficult to keep the length of manually cut heat shrink tubing consistent. This process is time-consuming, laborious, and results in lower cutting quality. Utility Model Content

[0004] The purpose of this invention is to provide a heat shrink tubing fixed-length cutting machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat shrink tubing fixed-length cutting machine, comprising a worktable, a cutting frame, and a fixed-length assembly. A horizontally arranged support groove is fixedly installed on the top of the worktable. The cutting frame is fixedly installed on the worktable. A first cylinder is fixedly installed on the top of the cutting frame. A support plate is fixedly installed on the piston end of the first cylinder. A second cylinder is fixedly installed on the top of the support plate. A blade holder is fixedly installed on the piston end of the second cylinder. A blade is fixedly installed on the bottom of the blade holder. Pressure blocks are fixedly installed on both sides of the bottom of the support plate at the blade.

[0006] The length-fixing assembly includes a length-fixing plate slidably mounted on the bracket, a screw is rotatably mounted on one side of the worktable located on the bracket, and one end of the length-fixing plate is sleeved on the screw and threadedly connected to the screw.

[0007] In a preferred embodiment, the slot is provided with a cutting groove located directly below the blade.

[0008] In a preferred embodiment, a connecting bolt runs through the interior of the tool holder, and the blade is mounted to the tool holder via the connecting bolt.

[0009] In a preferred embodiment, a scale is provided on one side of the workbench.

[0010] In a preferred embodiment, a handwheel is fixedly mounted on one end of the screw.

[0011] In a preferred embodiment, a guide rod is fixedly installed on the other side of the workbench, and the other end of the length plate is slidably sleeved on the guide rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This heat shrink tubing length cutting machine, by setting up a tray and a cutting frame, allows for easy cutting of heat shrink tubing. Simply place the heat shrink tubing into the tray, then activate the second cylinder to lower the blade, thus cutting the heat shrink tubing without manual hand-holding. This saves time and effort and improves cutting efficiency. By setting up a pressure block, before activating the second cylinder, the first cylinder can be activated to lower the support plate, causing the support plate to press the pressure block against both sides of the heat shrink tubing to be cut, fixing the heat shrink tubing and improving the stability of the heat shrink tubing during cutting. This results in a smoother cut and improved cutting quality.

[0014] This heat shrink tubing length cutting machine, by setting a length-fixing component, allows for the use of a handwheel to rotate a screw during the length-fixing process. This screw drives the length-fixing plate to slide along the groove, thereby adjusting the distance between the length-fixing plate and the cutting groove. During cutting, simply place one end of the heat shrink tubing against the length-fixing plate to quickly cut the heat shrink tubing to the correct length, ensuring that the cut length of the heat shrink tubing remains consistent and improving the cutting quality.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0021] Please see Figure 1-3 This utility model provides a heat shrink tubing fixed-length cutting machine, including a worktable 1, a cutting frame 2, and a fixed-length assembly 3. A horizontally arranged support groove 11 is fixedly installed on the top of the worktable 1. The cutting frame 2 is fixedly installed on the worktable 1, and a first cylinder 21 is fixedly installed on the top of the cutting frame 2. A support plate 22 is fixedly installed on the piston end of the first cylinder 21, and a second cylinder 23 is fixedly installed on the top of the support plate 22. A blade holder 24 is fixedly installed on the piston end of the second cylinder 23, and the bottom of the blade holder 24... The blade 25 is fixedly installed in the part, and the connecting bolt 27 passes through the inside of the blade holder 24. The blade 25 is installed to the blade holder 24 through the connecting bolt 27. The support groove 11 is located directly below the blade 25 and has a cutting groove 12. By setting the support groove 11 and the cutting frame 2, when cutting heat shrink tubing, you only need to put the heat shrink tubing into the support groove 11, and then start the second cylinder 23 to drive the blade 25 down to cut the heat shrink tubing. There is no need for manual cutting, which saves time and effort and improves cutting efficiency.

[0022] The support plate 22 has pressure blocks 26 fixedly installed on both sides of the blade 25 at its bottom. By setting the pressure blocks 26, the first cylinder 21 can be started before the second cylinder 23 is started, which will drive the support plate 22 to descend. This will cause the support plate 22 to drive the pressure blocks 26 to press the two sides of the heat shrink tubing to be cut, thereby fixing the heat shrink tubing, improving the stability of the heat shrink tubing during cutting, making the cut smoother, and improving the cutting quality.

[0023] Reference Figure 1 and Figure 3 The length-fixing component 3 includes a length-fixing plate 31 slidably mounted on the tray 11. A screw 32 is rotatably mounted on one side of the tray 11. A handwheel 33 is fixedly mounted on one end of the screw 32. One end of the length-fixing plate 31 is sleeved on the screw 32 and threadedly connected to the screw 32. A guide rod 34 is fixedly mounted on the other side of the tray 11. The other end of the length-fixing plate 31 is slidably sleeved on the guide rod 34. By setting the length-fixing component 3, when cutting heat shrink tubing to a fixed length, the handwheel 33 can be used to rotate the screw 32, causing the screw 32 to drive the length-fixing plate 31 to slide along the tray 11. This allows adjustment of the distance between the length-fixing plate 31 and the cutting groove 12. During cutting, only one end of the heat shrink tubing needs to be pressed against the length-fixing plate 31 to quickly cut the heat shrink tubing to a fixed length, ensuring that the cut length of the heat shrink tubing remains consistent and improving the cutting quality.

[0024] The workbench 1 is equipped with a scale 13 on one side, which facilitates precise control of the position of the length plate 31.

[0025] The working principle and usage process of this utility model are as follows: First, by setting up the tray 11 and the cutting frame 2, when cutting heat shrink tubing, simply place the heat shrink tubing into the tray 11, then activate the second cylinder 23 to drive the blade 25 down, thus cutting the heat shrink tubing. No manual hand-held cutting is required, saving time and effort and improving cutting efficiency. By setting up the pressure block 26, before activating the second cylinder 23, the first cylinder 21 can be activated to drive the support plate 22 down, causing the support plate 22 to drive the pressure block 26 to press the two sides of the heat shrink tubing to be cut. Fixing the heat shrink tubing improves stability during cutting, resulting in a smoother cut and improved cutting quality. By setting the length-fixing component 3, when cutting the heat shrink tubing to a fixed length, the screw 32 can be rotated using the handwheel 33, causing the screw 32 to drive the length-fixing plate 31 to slide along the groove 11. This allows adjustment of the distance between the length-fixing plate 31 and the cutting groove 12. During cutting, simply place one end of the heat shrink tubing against the length-fixing plate 31 to quickly cut the heat shrink tubing to a fixed length, ensuring that the cut length of the heat shrink tubing remains consistent and improving cutting quality.
