Description

Technical Field

[0001] The present application relates to the technical field of heat shrink tube processing, and in particular to a cutting device for heat shrink tubes. Background Art

[0002] Heat shrink tubing is in a glassy state at room temperature and becomes highly elastic after heating. During the heating process of the heat shrink tubing, as the temperature increases, the diameter of the heat shrink tubing decreases, while its length remains basically unchanged. Heat shrink tubing with better shrinkage can shrink 3 to 6 times, so heat shrink tubing is widely used for fixing and protecting various wires, cables, pipes, etc.

[0003] In order to obtain the required length of heat shrink tube, it is necessary to cut the heat shrink tube during the manufacturing process. In the prior art, a heat shrink tube intelligent cutting device with a publication number of CN219968216U can press the material tube on both sides of the blade during cutting to ensure a smooth cutting effect.

[0004] However, the pressing plate only presses the heat shrink tube from top to bottom along the vertical direction from one side, and the fixing position is relatively single, which has poor fixing effect on the heat shrink tube. At the same time, only a single feeding roller is provided, and the heat shrink tube is easily wrinkled due to concentrated force, and is easily offset during feeding;

[0005] Therefore, the present application provides a cutting device for heat shrink tubing to meet the demand. Utility Model Content

[0006] In view of this, the purpose of the present application is to provide a cutting device for heat shrink tubes, so as to achieve a good fixing effect through the cooperation of the adjustment block and the pressure block, and to achieve the purpose of stable feeding through the double-row pressure rollers.

[0009] Preferably, the guide block is arranged parallel to the adjustment block, and the bottom side wall of the top guide groove of the guide block is flush with the upper surface of the adjustment block.

[0010] Preferably, a mounting seat is connected to the side of the workbench, the pressure roller is rotatably connected to one side of the mounting seat through a bearing, one end of the mounting seat is fixedly connected to a servo motor, and the output end of the servo motor is fixedly connected to the pressure roller.

[0011] Preferably, the end of the slide rail is connected to a second cylinder, and the telescopic end of the second cylinder is fixedly connected to the side wall of the adjustment block.

[0012] Preferably, a limiting column is provided on the side wall of the adjusting block, and the other end of the limiting column passes through the pressing block.

[0013] Preferably, a side wall of the guide block and a side wall of the blade are in the same vertical plane.

[0014] Preferably, a spring is installed between the slider and the cylinder.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] In the above scheme, an adjusting block, a slider and a pressing block are provided, and the slider drives the pressing block to press on the top of the adjusting block, so as to fix the end of the heat shrink tube. When the pressing block and the adjusting block pull the heat shrink tube away from the pressing roller, the end of the heat shrink tube is well fixed, and the pressing roller fixes the heat shrink tube from the other end, so that the heat shrink tube maintains a good tension, ensures its straightness, and can avoid wrinkles on the heat shrink tube.

[0026] By inserting the heat shrink tube into the gap between the two pressing rollers 4 and overlapping one end of the heat shrink tube in the guide groove on the upper surface of the guide block 102, the guide block 102 can limit the activity space of the heat shrink tube, and the pressing roller 4 can be rotated to achieve the effect of directional feeding;

[0027] Slide the adjusting block 2 along the slide rail 101 to the position where the adjusting block 2 is in contact with the guide block 102, place one end of the heat shrink tube on the top of the adjusting block 2, align the edge of the heat shrink tube with the edge of the adjusting block 2, drive the blade 302 downward through the cylinder 1 301, and the slider 303 moves downward under the action of natural gravity. The slider 303 drives the pressing block 201 to press on the top of the adjusting block 2, so as to fix the end of the heat shrink tube;

[0028] Then slide the adjustment block 2 to select a suitable length, and the cylinder 1 301 extends again, driving the blade 302 to move downward to cut the heat shrink tube, thereby obtaining a heat shrink tube of the required length;

[0029] When the pressing block 201 and the adjusting block 2 pull the heat shrink tube away from the pressing roller 4, the end of the heat shrink tube 4 is well fixed, and the pressing roller 4 fixes the heat shrink tube from the other end, so that the heat shrink tube maintains good tension, ensures its straightness, and avoids wrinkles on the heat shrink tube.

[0030] In this embodiment, Figure 2-Figure 4As shown; the guide block 102 is arranged parallel to the adjustment block 2, and the bottom side wall of the top guide groove of the guide block 102 is flush with the upper surface of the adjustment block 2;

[0031] The guide block 102 is disposed on one side of the pressure roller 4 to prevent the heat shrink tube from collapsing so as to maintain the straightness of the heat shrink tube.

[0032] A mounting seat 5 is connected to the side of the workbench 1, and a pressure roller 4 is rotatably connected to one side of the mounting seat 5 through a bearing. A servo motor 501 is fixedly connected to one end of the mounting seat 5, and an output end of the servo motor 501 is fixedly connected to the pressure roller 4;

[0033] The servo motor 501 drives the pressing roller 4 to rotate, and the material discharge speed of the pressing roller 4 is controllable, so that the material discharge speed is consistent with the displacement speed of the adjustment block 2, thereby avoiding wrinkles on the heat shrinkable tube and ensuring the straightness of the heat shrinkable tube.

[0034] The end of the slide rail 101 is connected to a second cylinder 103, and the telescopic end of the second cylinder 103 is fixedly connected to the side wall of the adjustment block 2;

[0035] The air cylinder 103 is used to drive the adjusting block 2 to slide smoothly, and the length of the heat shrink tube after cutting is controlled by controlling the shrinking distance of the air cylinder 103, so as to achieve the effect of fixed-length cutting.

[0036] A limiting column 202 is provided on the side wall of the adjusting block 2, and the other end of the limiting column 202 penetrates through the pressing block 201;

[0037] The regulating block 2 and the pressing block 201 are kept parallel to each other through the limiting column 202 , so that the pressing block 201 can only move in the vertical direction to ensure that the pressing block 201 can fit the upper surface of the regulating block 2 .

[0038] A side wall of the guide block 102 and a side wall of the blade 302 are in the same vertical plane;

[0039] When the blade 302 moves downward to cut the heat shrink tube, the blade 302 is limited by the side wall of the guide block 102, and the cutting is more accurate. The guide block 102 plays a good guiding role on the heat shrink tube, so that the cutting part can be kept flat.

[0040] A spring 304 is installed between the slider 303 and the cylinder 1 301;

[0041] The elasticity of the spring 304 is utilized to exert a squeezing effect between the cylinder 1 301 and the slider 303 , so that the slider 303 continuously squeezes the pressing block 201 , thereby achieving the effect of fixing the position of the pressing block 201 .
