Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing processing, and in particular to a precision positioning slider for heat shrink tubing. Background Technology

[0002] Heat shrink tubing is a type of polymer material tubing that shrinks when heated. Its core function is to insulate, seal, protect, or mark components such as wires, cables, and solder joints. It is widely used in various industries, including electronics, power, and automotive. After being processed by a mold, heat shrink tubing forms a long, tubular blank, which can reach lengths of hundreds or even thousands of meters. It is then cut into sections according to the required length for actual use and packaged.

[0003] When using a cutting machine, the segment length is preset. After the cutting machine cuts the next segment on the blank, the worker manually picks up the blank and moves it forward. After the blank has moved the segment length, the cutting machine cuts again. The cutting speed is relatively slow, and the cutting machine may cause injury to the worker's hands.

[0004] Therefore, it is necessary to provide a precision positioning slider for heat shrink tubing to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a precision positioning slider for heat shrink tubing, which solves the problems of slow cutting speed and the potential for cutting machines to injure workers' hands.

[0006] To solve the above technical problems, the present invention provides a precision positioning slider for heat shrink tubing, comprising: a worktable, a tool holder provided on the worktable, a scale provided on the worktable, a cutting tool provided on one side of the tool holder, and further comprising: a movable block slidably disposed on one side of the worktable located on the scale, two insert rods provided on one side of the movable block, a push rod installed above the movable block, and a first pressure plate fixedly installed at the output end of the push rod; A placement seat is also fixedly installed on the workbench, and a gantry frame is provided on the placement seat. A slot is opened on the surface of the placement seat, and the slot is adapted to the insertion rod. A U-shaped frame is also slidably installed inside the gantry frame, and a second pressure plate is installed at the bottom of the U-shaped frame.

[0007] Preferably, a motor is mounted on the workbench, and a threaded rod is mounted on the output end of the motor, with the moving block threadedly connected to the threaded rod.

[0008] Preferably, two electromagnets are symmetrically arranged on both sides of the placement base, and armatures are installed at both ends of the U-shaped frame, with the electromagnets and armatures being compatible.

[0009] Preferably, the placement seat is also symmetrically provided with two first limiting posts, and each of the two first limiting posts is fitted with a first elastic element. The U-shaped plate is slidably installed on the two first limiting posts.

[0010] Preferably, a support frame is also installed on the workbench, a first rotating roller is rotatably mounted on the support frame, and a sliding frame is also provided above the first rotating roller on the support frame, a second rotating roller is rotatably mounted on the sliding frame.

[0011] Preferably, the support frame has two second limiting posts symmetrically arranged on its top, and each of the two second limiting posts is fitted with a second elastic element. The sliding frame is slidably mounted on the two second limiting posts.

[0012] Preferably, the worktable is also provided with a feeding port, which is located on one side of the tool holder.

[0013] Compared with related technologies, the precision positioning slider for heat shrink tubing provided by this utility model has the following advantages: This invention provides a precision positioning slider for heat shrink tubing. A motor drives a moving block to insert a rod into the slot to the bottom of the blank. A push rod presses one end of the blank against the rod, and the moving block reverses direction, moving the blank away from the placement seat. The length of the cutting segments is determined by a scale. A U-shaped frame and a second pressure plate press the middle section of the blank onto the placement seat, where it is cut by a cutting tool. For the next cut, the U-shaped frame and second pressure plate are raised to release the blank's restriction, repeating the previous operation to achieve continuous cutting of the blank. This eliminates the need for manual movement of the blank, preventing injury to workers from the cutting machine and improving processing speed. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 A precision positioning slider for heat shrink tubing includes: a worktable 1, on which a tool holder 11 is provided, and a scale 12 is also provided on the worktable 1. A cutting tool 2 is provided on one side of the tool holder 11. The slider also includes: a movable block 3 slidably disposed on one side of the worktable 1 at the scale 12, two insert rods 31 disposed on one side of the movable block 3, a push rod 32 mounted above the movable block 3, and a first pressure plate 33 fixedly mounted on the output end of the push rod 32. The workbench 1 is also fixedly installed with a placement seat 4, and a gantry frame 41 is provided on the placement seat 4. The surface of the placement seat 4 is provided with a slot 42, and the slot 42 is adapted to the insertion rod 31. A U-shaped frame 5 is also slidably installed inside the gantry frame 41, and a second pressure plate 51 is installed at the bottom of the U-shaped frame 5; During segmented processing, the cutting length is measured according to the set scale 12. The blank is cut by the cutting tool 2. Before operation, the blank is passed between the placement seat 4 and the second pressure plate 51. The sliding moving block 3 inserts the insert rod 31 into the slot 42 to the bottom of the blank. One end of the insert rod 31 is set as an inclined surface and its height is higher than the height of the slot 42. At this time, the blank is placed on the insert rod 31. The push rod 32 is activated to press one end of the blank onto the insert rod 31 through the first pressure plate 33. Then, the moving block 3 is moved backward to move one end of the blank. The movement of the moving block 3 is determined by the scale 12. After the moving block 3 stops, the U-shaped frame 5 drives the second pressure plate 51 to slide downwards within the gantry frame 41, pressing and limiting the blank on the placement seat 4. Then, the cutting tool 2 and the tool holder 11 work together to cut the blank. After that, the push rod 32 is activated to lift the first pressure plate 33 upwards, and the cut heat shrink tubing is removed. When making the next cut, the U-shaped frame 5 drives the second pressure plate 51 upwards. By repeating the previous operation, the purpose of continuous cutting of the blank is achieved. There is no need for the worker to manually move the blank, avoiding injury to the worker caused by the cutting machine and improving the processing speed.

[0018] Please refer to the following: Figure 1 and Figure 2 A motor 6 is installed on the workbench 1, and a threaded rod 61 is installed at the output end of the motor 6. The moving block 3 is threadedly connected to the threaded rod 61. When cutting during operation, the motor 6 is started, and the output end drives the threaded rod 61 to rotate, driving the moving block 3 to move towards the placement seat 4. After the first pressure plate 33 presses and limits one end of the blank, the motor 6 is started to drive the threaded rod 61 to rotate in the opposite direction, driving the moving block 3 to move the blank away from the placement seat 4.

[0019] Please refer to the following: Figure 2 and Figure 3 Two electromagnets 44 are symmetrically arranged on both sides of the placement base 4, and armatures 52 are installed at both ends of the U-shaped frame 5. The electromagnets 44 and the armatures 52 are adapted to each other. When it is necessary to limit the blank during operation, the electromagnet 44 is activated to attract the armature 52. The armature 52 drives the U-shaped frame 5 and the second pressure plate 51 to move downward, pressing the blank onto the placement seat 4 and limiting the blank.

[0020] Please refer to the following: Figure 3 The placement seat 4 is also symmetrically provided with two first limiting posts 43, and the surfaces of the two first limiting posts 43 are each fitted with a first elastic element 45. The U-shaped frame 5 is slidably installed on the two first limiting posts 43. During operation, the U-shaped frame 5 drives the second pressure plate 51 to move downward, and the second pressure plate 51 limits the blank. The U-shaped frame 5 slides on the surface of the first limiting post 43, and at the same time, the U-shaped frame 5 squeezes the first elastic element 45. When it is necessary to move the blank, the electromagnet 44 is turned off, and the first elastic element 45 pushes the U-shaped frame 5 and the second pressure plate 51 to rise upward, releasing the limitation on the blank.

[0021] Second Embodiment Please refer to the following: Figure 1 and Figure 5 The workbench 1 is also equipped with a support frame 7, on which a first rotating roller 71 is rotatably mounted. Above the first rotating roller 71, the support frame 7 is also provided with a sliding frame 72, on which a second rotating roller 73 is rotatably mounted. After processing, the billet is usually in the shape of a tube. When the diameter of the billet is large, the first pressure plate 33 and the second pressure plate 51 need to be raised to a higher height to limit the billet, which is inconvenient to operate.

[0022] In this embodiment, before operation, the sliding frame 72 and the second rotating roller 73 are raised upwards. Then, the blank is passed between the first rotating roller 71 and the second rotating roller 73. After the sliding frame 72 is lowered, the blank is pressed by the first rotating roller 71 and the second rotating roller 73, and the blank is flattened from a tubular shape, which facilitates the subsequent cutting of the blank.

[0023] Please refer to the reference again. Figure 1 and Figure 5 The support frame 7 has two second limiting posts 74 symmetrically arranged on its top. The surfaces of the two second limiting posts 74 are each fitted with a second elastic element 75. The sliding frame 72 is slidably mounted on the two second limiting posts 74. When the sliding frame 72 is lifted upward during operation, the sliding frame 72 slides on the surface of the second limiting post 74, squeezing the second elastic element 75. After the blank passes through the first rotating roller 71 and the second rotating roller 73, the sliding frame 72 is released, and the second elastic element 75 pushes the sliding frame 72 and the second rotating roller 73 downward to flatten the blank.

[0024] Please refer to the following: Figure 1 and Figure 2 The workbench 1 is also provided with a feeding port 13, which is located on one side of the tool holder 11; After the cutting tool 2 finishes cutting the blank during operation, the push rod 32 is activated to lift the first pressure plate 33, which contacts the limit of the cut blank. The blank falls down from the discharge port 13 under the action of gravity and falls into the pre-placed collection device. There is no need for workers to pick it up manually, which improves the processing speed.

[0025] The working principle of the precision positioning slider for heat shrink tubing provided by this utility model is as follows: Before operation, the billet is passed between the placement seat 4 and the second pressure plate 51. The motor 6 is started to drive the moving block 3, which in turn drives the insert rod 31 to insert into the slot 42 to the bottom of the billet. The push rod 32 is then started to press one end of the billet onto the insert rod 31 via the first pressure plate 33. After that, the motor 6 is started to drive the moving block 3 to move the billet away from the placement seat 4. The moving distance of the moving block 3 is determined by the scale 12. After the moving block 3 stops, the electromagnet 44 is started to attract the armature 52. The armature 52 drives the U-shaped frame 5 and the second pressure plate 51 to move downwards, pressing the billet firmly onto the placement seat 42. The blank is placed on seat 4, and simultaneously the U-shaped frame 5 compresses the first elastic element 45. Then, the cutting tool 2 and the tool holder 11 work together to cut the blank. After that, the push rod 32 is activated to lift the first pressure plate 33 upward, and the cut heat shrink tubing is removed. When cutting again, the electromagnet 44 is turned off, and the first elastic element 45 pushes the U-shaped frame 5 and the second pressure plate 51 upward to release the constraint on the blank. By repeating the previous operation, the blank can be continuously cut without the need for the worker to manually move the blank, avoiding injury to the worker from the cutting machine and improving the processing speed. The first rotating roller 71 and the second rotating roller 73 are set. Before operation, the sliding frame 72 and the second rotating roller 73 are lifted upward. The sliding frame 72 compresses the second elastic element 75. Then, the blank is passed between the first rotating roller 71 and the second rotating roller 73. After the sliding frame 72 is lowered, the second elastic element 75 pushes the sliding frame 72 and the second rotating roller 73 downward to press the blank, flattening the blank from a tubular shape, which is convenient for subsequent cutting of the blank.
