Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing cutting, and in particular to an automated heat shrink tubing cutting device. Background Technology

[0002] Heat shrink tubing, also known as heat shrink protective tubing, provides insulation protection for wires, cables, and wire terminals. It features high-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion resistance, and is widely used for insulation protection of various wire harnesses, solder joints, and inductors, as well as rust and corrosion prevention of metal pipes and rods.

[0003] During the production of heat shrink tubing, after the initial processing is completed, it is aligned and rolled up. However, in actual use, the long rolled heat shrink tubing needs to be cut into shorter lengths.

[0004] Currently, automated cutting mechanisms use a downward-moving cutting blade to cut the heat shrink tubing to the required length. However, existing automated cutting devices do not have a support device at the bottom when cutting the tubing. This causes the top of the heat shrink tubing to be compressed first, bending the bottom of the tubing. As a result, the pressure on the upper and lower sides of the cut end is different, which can easily lead to uneven cuts as the cutting blade continues to cut.

[0005] Therefore, it is necessary to provide an automated heat shrink tubing cutting device to solve the above-mentioned technical problems. Utility Model Content

[0006] This utility model provides an automated cutting device for heat shrink tubing, which solves the problem that existing automated cutting devices do not have a support device at the bottom when cutting the tubing. This causes the top of the heat shrink tubing to be squeezed first when it is cut, which in turn squeezes and bends the bottom of the heat shrink tubing. As the cutting blade continues to cut, the pressure on the upper and lower sides of the cut end of the heat shrink tubing is different, which easily leads to uneven cuts of the heat shrink tubing.

[0007] To solve the above-mentioned technical problems, this utility model provides an automated heat shrink tubing cutting device, comprising: a workbench; Two traction and transportation devices are respectively arranged on the upper and lower sides of the front of the workbench; A guide box is fixedly installed on one side of the center of the front of the workbench. A slot is provided on one side of the top of the guide box, and a support slot is provided in the middle of one side of the guide box. A fixing box is fixedly installed on one side of the front of the workbench and on one side of the top of the guide box. Lifting components are fixedly installed on both sides inside the fixing box, and a cutting blade is fixedly connected to the bottom end of the output shaft of the lifting component.

[0008] Preferably, the traction transport device includes a motor box, a first drive component, a rotating gear, a traction belt, and traction gear blocks. The motor box is located in the middle of the front of the workbench. The two first drive components are respectively fixedly installed on both sides inside the workbench. The rotating gear is fixedly connected to the output shaft end of the first drive component. The traction belt is sleeved on the outer surface of the two rotating gears. The plurality of traction gear blocks are equidistantly arranged on the inner surface of the traction belt.

[0009] Preferably, a guide block is fixedly installed in the middle of the left side of the front of the workbench, and a connecting groove is opened in the middle of one side of the guide block.

[0010] Preferably, a material feeding box is fixedly installed at the bottom right side of the front of the workbench.

[0011] Preferably, adjustment devices are provided on both sides of the top of the front of the workbench, and threaded holes are provided on both sides of the top of one of the motor boxes.

[0012] Preferably, the adjustment device includes a mounting plate, a second driving member, and a threaded column. The mounting plate is fixedly installed on one side of the top of the worktable, the second driving member is fixedly installed on the top of the mounting plate, and the top end of the threaded column is fixedly connected to the bottom end of the output shaft of the second driving member.

[0013] Preferably, the threaded post engages with the interior of the threaded hole.

[0014] Compared with related technologies, the automated heat shrink tubing cutting device provided by this utility model has the following advantages: This invention provides an automated cutting device for heat shrink tubing. The heat shrink tubing is pulled into the guide box by a traction transport device and cut inside the groove. The heat shrink tubing is supported by the groove, allowing the cutting blade to move downward from the slot into the groove to cut the heat shrink tubing. During the cutting process, because the bottom of the heat shrink tubing is supported by the groove, the pressure on its top and bottom can be kept balanced, effectively preventing the bottom of the heat shrink tubing from bending due to compression. This ensures the flatness of the cut end of the heat shrink tubing during cutting, greatly improving the cutting quality and efficiency. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 and Figure 3 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an automated heat shrink tubing cutting device provided by this utility model; Figure 2 for Figure 1 The diagram shown is a structural schematic of the traction and transportation device. Figure 3 for Figure 1 The enlarged schematic diagram of part A is shown.

[0019] An automated heat shrink tubing cutting device includes: a workbench 1; Two traction and transport devices 4 are respectively arranged on the upper and lower sides of the front of the workbench 1. Guide box 6 is fixedly installed on one side of the front center of the workbench 1. A slot 8 is provided on one side of the top of the guide box 6, and a support slot 7 is provided in the middle of one side of the guide box 6. The fixing box 9 is fixedly installed on one side of the front of the workbench 1 and on one side of the top of the guide box 6. Lifting members 10 are fixedly installed on both sides inside the fixing box 9. A cutting blade 11 is fixedly connected to the bottom end of the output shaft of the lifting member 10.

[0020] The traction transport device 4 includes a motor box 41, a first drive component 42, a rotating gear 43, a traction belt 44, and traction tooth blocks 45. The motor box 41 is located in the middle of the front of the workbench 1. The two first drive components 42 are respectively fixedly installed on both sides inside the workbench 1. The rotating gear 43 is fixedly connected to the output shaft end of the first drive component 42. The traction belt 44 is sleeved on the outer surface of the two rotating gears 43. A plurality of traction tooth blocks 45 are equidistantly arranged on the inner surface of the traction belt 44.

[0021] Preferably, a guide block 2 is fixedly installed in the middle of the left side of the front of the workbench 1, and a connecting groove 3 is opened in the middle of one side of the guide block 2.

[0022] A feeding box 12 is fixedly installed on the bottom right side of the front of the workbench 1.

[0023] The traction and transport device 4 drives the rotating gear 43 to rotate through the first driving component 42, which in turn drives the traction belt 44 and the traction tooth block 45 to move, realizing stable traction and transport of the heat shrink tubing and providing a reliable guarantee for automated cutting. When the rotating gear 43 rotates, the tooth block on its surface meshes with the traction tooth block 45 on the inner surface of the traction belt 44, causing the traction belt 44 to rotate on the outer surface of the two rotating gears 43, thus tractioning the heat shrink tubing to move.

[0024] The first driving component 42 adopts a servo motor structure, and the lifting component 10 adopts a hydraulic cylinder structure.

[0025] The working principle of the automated heat shrink tubing cutting device provided by this utility model is as follows: During operation, the heat shrink tubing is first placed between the two traction transport devices 4 through the connecting groove 3. As the two traction transport devices 4 clamp the heat shrink tubing and pull it to move into the inside of the support groove 7, it is placed there.

[0026] The lifting component 10 output shaft moves and pushes the cutting blade 11 downward. The cutting blade 11 enters the interior of the support groove 7 through the slot 8 and cuts the heat shrink tubing placed on the support groove 7. Because the bottom of the heat shrink tubing is supported by the support groove 7, the cutting blade 11 presses the heat shrink tubing downward, so that the bottom of the cutting end is supported and cannot move, keeping the cut flat.

[0027] After the cutting is completed, the cutting blade 11 moves upward to return to its original position, and the traction transport device 4 continues to pull the heat shrink tubing into the inside of the tray 7, pushing the cut heat shrink tubing out of the tray 7 and dropping it into the unloading box 12 for discharge. This process is repeated to achieve automated cutting.

[0028] Compared with related technologies, the automated heat shrink tubing cutting device provided by this utility model has the following advantages: This utility model provides an automated cutting device for heat shrink tubing. The heat shrink tubing is cut inside the groove 7 of the guide box 6 after being pulled in by the traction transport device 4. The heat shrink tubing is supported by the groove 7, which allows the cutting blade 11 to move downward from the slot 8 into the groove 7 to cut the heat shrink tubing. During the cutting process, because the bottom of the heat shrink tubing is supported by the groove 7, the pressure on its top and bottom can be kept balanced, effectively avoiding the phenomenon of the bottom of the heat shrink tubing bending due to compression. This ensures the flatness of the cut end of the heat shrink tubing during cutting, greatly improving the cutting quality and efficiency.

[0029] Second Embodiment Please refer to the following: Figure 4 and Figure 5 Based on the automated heat shrink tubing cutting device provided in the first embodiment of this application, the second embodiment of this application proposes another automated heat shrink tubing cutting device. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0030] Specifically, the difference in the second embodiment of this application regarding the automated cutting device for heat shrink tubing is that adjustment devices 13 are provided on both sides of the top front of the workbench 1, and threaded holes 14 are provided on both sides of the top of one of the motor boxes 41.

[0031] The adjustment device 13 includes a mounting plate 131, a second driving member 132, and a threaded post 133. The mounting plate 131 is fixedly installed on one side of the top of the workbench 1, the second driving member 132 is fixedly installed on the top of the mounting plate 131, and the top end of the threaded post 133 is fixedly connected to the bottom end of the output shaft of the second driving member 132.

[0032] The threaded post 133 is threaded into the interior of the threaded hole 14.

[0033] Two traction transport devices 4 are distributed vertically on the front of the workbench 1. The motor box 41 of the top traction transport device 4 is threadedly connected to the outer surface of the threaded post 133 through the threaded hole 14, while the bottom traction transport device 4 does not have a threaded hole 14. The bottom end of the threaded post 133 is rotatably mounted on the top of the motor box 41 of the bottom traction transport device 4.

[0034] The second drive unit 132 adopts a servo motor structure.

[0035] The working principle of the automated heat shrink tubing cutting device provided by this utility model is as follows: During operation, the output shaft of the second drive unit 132 is first controlled to rotate, which drives the threaded column 133 to rotate. The rotating threaded column 133 engages with the threaded hole 14 of the traction transport device 4 located at the top, so that the traction transport device 4 located at the top slides up or down along the worktable 1, adjusting the distance between the two traction transport devices 4.

[0036] Compared with related technologies, the automated heat shrink tubing cutting device provided by this utility model has the following advantages: This invention provides an automated cutting device for heat shrink tubing. By adjusting the configuration of device 13, the height of one of the motor boxes 41 can be adjusted according to actual needs.
