Description

Technical Field

[0001] The utility model belongs to the technical field of cold shrinkable tubes, and particularly relates to a cutting mechanism for the production and processing of cold shrinkable tubes. Background Technique

[0002] A cold shrinkable tube generally refers to a tubular cable accessory that uses cold shrinkage technology and has functions such as insulation, sealing, and protection. Cold shrinkage technology is also called pre-expansion technology. Since it shrinks by elastic shrinkage force at room temperature instead of heating and shrinking like heat shrinkable film materials, it is also known as cold shrinkage technology. The common materials for cold shrinkable tubes are silicone rubber and ethylene propylene rubber. Cold shrinkable tubes have the advantages of light weight, convenient and fast operation, no need for tools, wide application range, and few product models.

[0003] During the production process of cold shrinkable tubes, a cutting device is generally arranged at the discharge port to facilitate the cutting of the cold shrinkable tubes after production. In the prior art, the fixing structure on the cutting device is generally fixed, which is not convenient for disassembly, so that only cold shrinkable tubes of the same size can be cut and processed, thus reducing the application range of the existing cutting device.

[0004] For the problems in the related art, no effective solution has been proposed yet. Content of the Utility Model

Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the utility model.

[0032] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating the orientation or position relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation of the present utility model.

[0033] Please refer to Figures 1 - 7 As shown, the present utility model is a cutting mechanism for the production and processing of cold-shrinkable tubes, including a workbench 1. A cutting component 2 is fixedly connected to the top end of the workbench 1. An adjusting component 3 is arranged on the top end of the workbench 1. A positioning component 4 is slidably arranged inside the workbench 1. One end of the positioning component 4 is fixedly connected to a clamping component 5. A fixed mold 6 is arranged on the top end of the positioning component 4. One side of the fixed mold 6 is in contact with one side of the clamping component 5.

[0034] When in use, the position of the adjusting component 3 is adjusted by stretching it, and then the shrink tube is passed through one end of the fixed mold 6 and one end of it is fitted with one side of the adjusting component 3 to complete the adjustment of the cutting length of the shrink tube, and then the cutting component 2 is started to cut it. When the fixed mold 6 needs to be replaced, the clamping component 5 is rotated to move it, and the clamping state of the fixed mold 6 is released, and then the fixed mold 6 is slid. Since the bottom end of the fixed mold 6 is sleeved with the outer surface of the positioning component 4, when the fixed mold 6 moves, it can drive the positioning component 4 set inside it to move, and then the fixed mold 6 can be pulled up to make it detach from the positioning component 4, thereby completing the disassembly of the fixed mold 6, and then the bottom end of the fixed mold 6 of other models is sleeved on the outer surface of the positioning component 4, and then the clamping component 5 is pushed to move it, and the replaced fixed mold 6 is clamped and fixed, which is more convenient.

[0035] The utility model rotates the clamping component 5 to move it and releases the clamping state of the fixed mold 6, and then slides the fixed mold 6. Since the bottom end of the fixed mold 6 is sleeved with the outer surface of the positioning component 4, when the fixed mold 6 moves, it can drive the positioning component 4 set inside it to move, and then the fixed mold 6 can be lifted up to make it separate from the positioning component 4, thereby completing the disassembly of the fixed mold 6, and then the bottom end of the fixed mold 6 of other types is sleeved on the outer surface of the positioning component 4, and then the clamping component 5 is pushed to move it, and the replaced fixed mold 6 is clamped and fixed, so that the cutting mechanism used for the production and processing of cold shrink tubes is convenient for replacing fixed molds 6 of different types, thereby improving its scope of application.

[0036] In one embodiment, for the above-mentioned cutting component 2, the cutting component 2 includes a support arm 201, the bottom end of the support arm 201 is fixedly connected to the top end of the workbench 1, an electric push rod 202 is fixedly installed at the bottom end of the support arm 201, and a cutting knife 203 is fixedly installed at the telescopic end of the electric push rod 202.

[0037] By starting the electric push rod 202, the cutting knife 203 fixedly installed at its telescopic end can be driven to move up and down, thereby facilitating the cutting of the cold shrink tube.

[0038] In one embodiment, for the above-mentioned adjustment component 3, the adjustment component 3 includes an extension plate 301 and a fixing seat 302, the outer surface of the extension plate 301 is slidably arranged inside the workbench 1, and a baffle 303 is fixedly connected to one side of the extension plate 301;

[0039] The bottom end of the fixed seat 302 is fixedly installed on the top end of the workbench 1. A fastening bolt 304 is threadedly connected inside the fixed seat 302, and one end of the fastening bolt 304 is in contact with the top end of the extension plate 301.

[0040] By rotating the fastening bolt 304 to cooperate with the internal thread of the fixed seat 302, it can move upward, and then the bottom end of the fastening bolt 304 can release the extrusion fixation on the top end of the extension plate 301. Thus, by pulling the baffle 303, the extension plate 301 fixedly connected to one side of it can be driven to move, and then it is convenient to adjust the distance between the baffle 303 and the workbench 1. When the appropriate distance is adjusted, rotate the fastening bolt 304 in the reverse direction to make it move downward in cooperation with the internal thread of the fixed seat 302 and extrude and fix the top end of the extension plate 301, thereby completing the position fixation of the extension plate 301 and the baffle 303, which is relatively convenient.

[0041] In one embodiment, for the above-mentioned positioning assembly 4, the positioning assembly 4 includes a sliding groove 401 opened on the top end of the workbench 1. A sliding block 402 is slidably arranged inside the sliding groove 401. A positioning column 403 is fixedly connected to the top end of the sliding block 402, and the outer surface of the positioning column 403 is sleeved with the bottom end of the fixed mold 6.

One end of the spring 405 is fixedly connected with the inner wall of the sliding block 402. One end of the telescopic tube 404 is fixedly connected with one side of the clamping assembly 5.

[0043] When the fixed mold 6 needs to be positioned and installed, by pulling the positioning column 403, the sliding block 402 fixedly connected to its bottom end can be driven to move. When the sliding block 402 moves, it can drive the telescopic tube 404 fixedly connected inside it to perform telescopic movement, and at the same time, the spring 405 fixedly connected to its inner wall is compressed. Then, the bottom end of the fixed mold 6 is sleeved on the outer surface of the positioning column 403. Then, under the elastic force of the spring 405, the telescopic tube 404 and the sliding block 402 can be pushed to drive the positioning column 403 to move. When the positioning column 403 moves, it can drive the fixed mold 6 sleeved on its outer surface to move, and then one side of it is in contact with the inner side of the clamping assembly 5, thereby completing the pre-installation of the fixed mold 6.

[0044] In one embodiment, for the above-mentioned clamping assembly 5, the clamping assembly 5 includes a U-shaped frame 501 and two groups of clamping blocks 502. One side of the U-shaped frame 501 is fixedly connected to one end of the telescopic tube 404. One side inside the U-shaped frame 501 is fixedly installed with a rotating seat 503. Inside the rotating seat 503, a threaded cylinder 504 is rotatably arranged. A threaded rod 505 is threadedly connected inside the threaded cylinder 504. One end of the threaded rod 505 is fixedly installed on one side of the workbench 1.

[0045] The bottom end of one group of the clamping blocks 502 is fixedly installed on the top end of the workbench 1, and the bottom end of the other group of the clamping blocks 502 is fixedly installed on the top end of the U-shaped frame 501.

[0046] By rotating the threaded cylinder 504 to release the threaded connection with the threaded rod 505, the restriction of the U-shaped frame 501 is indirectly released. Then, when the telescopic tube 404 moves under the push of the spring 405, it can drive the U-shaped frame 501 fixedly connected to its one side to move. When the U-shaped frame 501 moves, it can drive the clamping block 502 fixedly installed on its top end to move, thereby releasing the restriction on the fixed mold 6 and facilitating the disassembly of the fixed mold 6.

[0047] In one embodiment, for the above-mentioned sliding groove 401, a limiting groove 7 is formed on the inner wall of the sliding groove 401. A limiting block 8 is slidably arranged inside the limiting groove 7. One side of the limiting block 8 is fixedly connected to one side of the sliding block 402.

[0048] When the sliding block 402 moves, it can drive the limiting block 8 fixedly connected to its one side to move. Since the outer surface of the limiting block 8 is slidably arranged inside the limiting groove 7, when the limiting block 8 moves, it can slide inside the limiting groove 7, thereby improving the stability of the sliding block 402 during the movement process.

[0049] In one embodiment, for the above-mentioned workbench 1, a connecting groove 9 is formed on the top end of the workbench 1. An indicating block 10 is slidably arranged inside the connecting groove 9. The bottom end of the indicating block 10 is fixedly connected to the top end of the extension plate 301. A scale line 11 is arranged on the top end of the workbench 1.

[0050] When the extension plate 301 moves, it can drive the indicating block 10 fixedly connected to its top end to move. Since the scale line 11 is arranged on the top end of the workbench 1 and the scale line 11 is arranged on one side of the connecting groove 9, when the indicating block 1 moves, the moving distance of the extension plate 301 can be obtained according to the scale line 11, thereby facilitating the control and adjustment of the moving distance of the extension plate 301.

[0051] Through the above technical scheme, 1. By rotating the clamping assembly 5 to move it, and releasing the clamping state of the fixed mold 6, and then sliding the fixed mold 6, since the bottom end of the fixed mold 6 is sleeved with the outer surface of the positioning assembly 4, when the fixed mold 6 moves, it can drive the positioning assembly 4 set inside it to move, and then the fixed mold 6 can be pulled up to make it separate from the positioning assembly 4, thereby completing the disassembly of the fixed mold 6, and then the bottom end of the fixed mold 6 of other models is sleeved on the outer surface of the positioning assembly 4, and then the clamping assembly 5 is pushed to move it, and the replaced fixed mold 6 is clamped and fixed, so that the cutting mechanism used for the production and processing of cold shrink tubes is convenient for replacing fixed molds 6 of different models, thereby improving its scope of application;

[0052] 2. The threaded connection between the threaded cylinder 504 and the threaded rod 505 is released by rotating the threaded cylinder 504, thereby indirectly releasing the restriction of the U-shaped frame 501. When the telescopic tube 404 moves with the push of the spring 405, it can drive the U-shaped frame 501 fixedly connected on one side to move. When the U-shaped frame 501 moves, it can drive the clamping block 502 fixedly installed on the top thereof to move, thereby releasing the restriction on the fixed mold 6, making it easier to disassemble and install the fixed mold 6.
