Description

Technical Field

[0001] This application relates to the field of heat shrink tubing cutting technology, and more particularly to a tubing cutting device. Background Technology

[0002] Heat shrink tubing is a specially made heat shrink sleeve made of polyolefin material, also known as EVA material. The outer layer is made of high-quality, soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance and wear resistance, while the inner layer has the advantages of low melting point, waterproof sealing and high adhesion. Heat shrink tubing is usually required at both ends of power leads.

[0003] Because heat shrink tubing is a flexible tube, existing tubing cutting devices often result in incomplete cuts during the heat shrink tubing cutting process, leading to substandard product quality and affecting normal use by users. Utility Model Content

[0008] Optionally, the clamping mechanism includes a clamping connecting seat, which is slidably disposed on the base, and the driving member is connected to the clamping connecting seat.

[0009] Optionally, the feeding mechanism is provided with two guide members at one end near the clamping mechanism. Both guide members are slidably disposed on the base, and a rear guide channel is formed between the two guide members. The rear guide channel is used to limit the radial position of the pipe.

[0011] Optionally, the feeding mechanism is provided with a pressing component at one end near the material tray. The pressing component includes a rotating shaft and a pressing block.

[0015] Optionally, the pipe cutting device includes a waste suction assembly for absorbing waste generated by the cutting mechanism during pipe cutting.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art: This application embodiment is mainly applied to the cutting of flexible tubing such as heat shrink tubing. The base is horizontally fixed, and the material tray is rotatably mounted on the base via a hole-shaft fit or a hinge structure. The material tray can be passively unwound or the heat shrink tubing can be released at a steady speed via a damper. The feeding mechanism is slidably connected to the base using a linear guide rail. The cutting connecting seat of the cutting mechanism is also slidably fitted to the linear guide rail of the base and located downstream of the feeding mechanism. A disc cutter is rotatably mounted on the cutting connecting seat via a small motor. The cutter rotates while sliding forward with the connecting seat, completing the rotational shearing in front of the clamping mechanism. The clamping mechanism is fixed to the cutting... On the discharge side of the mechanism, the connecting component is a platform that can rotate around the axis of the heat shrink tubing. Two clamping components are symmetrically installed on the connecting component via a slider guide structure. The driving component can be a rotary cylinder or a motor. After the two clamping components clamp the heat shrink tubing, the driving component can drive the connecting component and the clamping components to rotate, thereby causing the heat shrink tubing to rotate. After the cutting component cuts half of the heat shrink tubing, due to the flexible nature of the heat shrink tubing, the rotation of the driving component will bring the uncut section of the heat shrink tubing close to the cutting component, thereby cutting the other half of the heat shrink tubing and ensuring the integrity of the cut. The clamping mechanism drives the heat shrink tubing to rotate through the rotating platform, so that the cutter only needs to make one half-cut to complete the full circumference cut by means of the tubing's rotation. This reduces the load on the cutter and avoids excessive compression, ensuring a complete cut and no flattening of the tubing, achieving continuous, high-quality, and deformation-free cutting of flexible heat shrink tubing.

[0025] To address the technical problem that existing heat shrink tubing cutting equipment often results in incomplete cuts during the cutting process, leading to substandard product quality and affecting normal user operation, this application provides a tubing cutting device 100. By setting a rotatable connector 51 and a clamping member 53 in the clamping mechanism 5 to drive the heat shrink tubing to rotate, the cutting piece 42 only needs to make one half-cut to complete the full circumference cut by means of the tubing's rotation. This reduces the load on the cutting blade and avoids excessive compression, ensuring a complete cut and no flattening of the tubing, thus achieving continuous, high-quality, and deformation-free cutting of flexible heat shrink tubing.

[0026] Figures 1 to 6 A pipe cutting device 100 provided in this application embodiment includes a base 1, a material tray 2, a feeding mechanism 3, a cutting mechanism 4, and a clamping mechanism 5. The material tray 2 is rotatably disposed on the base 1 and is used to receive or release pipes. The feeding mechanism 3 is disposed on the base 1 and is used to drive the pipes to move. The cutting mechanism 4 includes a cutting connecting seat 41 and a cutting piece 42. The cutting connecting seat 41 is disposed on the base 1, and the cutting piece 42 is rotatably disposed on the cutting connecting seat 41. The clamping mechanism 5 is located at the end of the cutting mechanism 4 away from the feeding mechanism 3. The clamping mechanism 5 includes a connecting piece 51, a driving piece 52, and a clamping piece 53. The clamping piece 53 is slidably disposed on the connecting piece 51. The driving piece 52 can drive the connecting piece 51 to rotate, and the clamping piece 53 is used to clamp the pipes.

[0027] In this embodiment, the tube cutting device 100 is mainly used for cutting flexible tubes such as heat shrink tubing. The base 1 is horizontally fixed and is generally made of cast iron or stainless steel. The base 1 can be a large platform or support structure. The material tray 2 is rotatably installed on the base 1 through a hole-shaft fit or a hinge structure. The material tray 2 can passively unwind or release the heat shrink tubing at a steady speed through a damper. The center of the material tray 2 generally has a rotating shaft, and its shape is made of plastic material through injection molding. The feeding mechanism 3 is slidably connected to the base 1 through a linear guide rail. After the feeding mechanism 3 clamps the heat shrink tubing, it is slidably connected to the base 1 to feed the material. The cutting connecting seat 41 of the cutting mechanism 4 is also slidably fitted with the linear guide rail of the base 1 and is located downstream of the feeding mechanism 3. A disc cutter is mounted on the cutting connecting seat 41 by a small motor. The cutter rotates while sliding forward with the connecting seat and completes rotational cutting in front of the clamping mechanism 5.

[0028] It should be noted that the clamping mechanism 5 is fixed on the discharge side of the cutting mechanism 4 so that the outer clamping mechanism 5 can clamp the heat shrink tubing while the cutting component 42 cuts the heat shrink tubing, ensuring the cutting quality. The connecting component 51 of the clamping mechanism 5 is a platform that can rotate around the axis of the heat shrink tubing. The two clamping components 53 are symmetrically installed on the connecting component 51 through the slider guide structure. The driving component 52 can be a rotary cylinder or a motor. After the two clamping components 53 clamp the heat shrink tubing, the driving component 52 can drive the connecting component 51 and the clamping components 53 to rotate, thereby causing the heat shrink tubing to rotate. After the cutting component 42 cuts half of the heat shrink tubing, due to the flexible nature of the heat shrink tubing, the rotation of the driving component 52 will cause the uncut section of the heat shrink tubing to approach the cutting component 42, thereby cutting the other half of the heat shrink tubing, ensuring the integrity of the cutting by the cutting component 42.

[0029] In the tubing cutting device 100 of this application, the material tray 2 and the base 1 rotate to keep the unwinding resistance constant, preventing the heat shrink tubing from being stretched and deformed; the feeding wheel flexibly clamps and slides synchronously, which can accurately control the feeding length and not leave indentations on the tube wall; the disc cutter rotates and cuts in front of the clamping point, resulting in a continuous and flat cut, completely eliminating uncut or burr defects; the clamping mechanism 5 drives the heat shrink tubing to rotate through the rotating platform, so that the cutter only needs to make one half-cut to complete the full circumference cut by means of the tube's rotation, which reduces the cutter load and avoids excessive compression, ensuring a complete cut and no flattening of the tube body, and achieving continuous, high-quality, and deformation-free flexible heat shrink tubing cutting.

[0030] Please see Figures 2 to 4 To prevent the clamping member 53 from clamping too much and causing the heat shrink tubing to deform, the clamping mechanism 5 also includes a guide shaft 54. One end of the guide shaft 54 ​​is connected to the connector 51, and the other end of the guide shaft 54 ​​is used to extend into the heat shrink tubing. The guide shaft 54 ​​is arranged along the rotation axis direction of the connector 51.

[0031] In one embodiment, the guide shaft 54 ​​is made of stainless steel or aluminum alloy. One end is connected to the rotation center of the connector 51 via bolts or clips, and the other end is machined into a hemispherical or conical shape for inserting the heat shrink tubing and fitting it with the tubing with a clearance. The clamping member 53 is a rectangular block or semi-circular arc structure made of aluminum alloy or plastic. The clamping centers of the two clamping members 53 coincide with the axis of the guide shaft 54. When the clamping members 53 are close to each other, the heat shrink tubing is clamped between the outer wall of the guide shaft 54 ​​and the clamping members 53. The guide shaft 54 ​​supports the flexible heat shrink tubing from the inside, and the two clamping members 53 only provide radial restraint without the need for strong clamping, completely avoiding flattening and deformation. The axis of the guide shaft 54 ​​coincides with the clamping centers of the two clamping members 53, ensuring that the tubing remains concentric during the rotational cutting process, ensuring that the cutting member 42 cuts evenly and the cut is complete and burr-free.

[0032] Please see Figures 2 to 4 In order to further adapt the clamping member 53 to the shape of the heat shrink tubing, the clamping mechanism 5 includes two clamping members 53. Each clamping member 53 has a clamping groove 53a at the end away from the connector 51. When the two clamping members 53 abut, the end of the guide shaft 54 ​​away from the connector 51 is located in the clamping groove 53a.

[0033] In one embodiment of this application, a through-circular clamping groove 53a is milled at the suspended end of each clamping member 53, the groove shape matching the outer circumferential surface of the heat shrink tubing; when the two clamping members 53 are closed, the groove wall encircles the tubing, and at the same time, the distal end of the guide shaft 54 ​​also extends into the clamping groove 53a, forming a nested relationship of "inner shaft and outer shell". The clamping member 53 can be made of aluminum alloy integrally machined and then anodized to obtain a high-rigidity, wear-resistant hard shell; or it can be made of wear-resistant POM plastic injection molding, and a layer of flexible silicone is formed on the groove surface to form an elastic buffer. The end of the guide shaft 54 ​​is machined into a ball head or rounded, which facilitates insertion and does not scratch the tube wall during rotation; the inner wall of the clamping groove 53a is used to abut against the outer wall of the heat shrink tubing to achieve axial positioning and prevent the tubing from moving back and forth during the rotational cutting process.

[0034] After the clamping groove 53a and guide shaft 54 ​​clamp the heat shrink tubing, the clamping part 53 only needs light pressure to maintain circumferential fixation, avoiding flat marks or local thinning caused by excessive pressure in traditional flat-mouth clamps; the end face of the clamping part 53 is naturally aligned with the tubing, and the cut is perpendicular to the axis, eliminating bevel defects. The aluminum alloy hard shell solution provides stable high clamping accuracy and is suitable for scenarios with slightly thicker walls and high cutting speeds; the POM-silicone composite solution utilizes elastic deformation to adapt to slight differences in tubing diameter and is suitable for thin-walled, easily deformable heat shrink tubing. Both material choices can ensure complete rotational cutting and no damage to the tubing without increasing clamping force, significantly improving cut quality and consistency.

[0035] Please see Figure 2In order for the pipe cutting device 100 of this application to cut thermoplastic pipes of different lengths, the clamping mechanism 5 includes a clamping connecting seat 55, which is slidably disposed on the base 1, and the driving member 52 is connected to the clamping connecting seat 55.

[0036] In this embodiment, a linear slider is installed on the bottom surface of the clamping connector 55, forming a sliding pair with the linear guide rail on the base 1. The driving component 52 of the connector 51 is fixedly connected to the clamping connector 55 by bolts or buckles, ensuring that the driving component 52 and the connector 51 can slide normally on the base 1 during the sliding process of the clamping connector 55, thereby adjusting the distance between the cutting component 42 and the clamping mechanism 5, that is, ensuring that the pipe cutting device 100 can cut thermoplastic pipes of different lengths. The top surface of the clamping connector 55 still retains the original components such as the rotatable connector 51, guide shaft 54 ​​and clamping component 53, so that the clamping, rotation and displacement functions are integrated into one. Rubber buffer blocks and metal limit screws are provided at both ends of the displacement stroke to prevent overtravel impact; a stainless steel scale can be attached to the side wall of the guide rail for easy manual and quick zero-position calibration. The clamping connector 55 can slide back and forth along the base 1. The feeding mechanism 3 only needs to send the heat shrink tube to the fixed reference point, and the clamping mechanism 5 can move to change the cutting length. There is no need to repeatedly adjust the feeding parameters, and the changeover time is greatly shortened.

[0037] Please see Figure 3 and Figure 4 In order to ensure that the thermoplastic tube can be properly guided and initially limited on the side of the cutting part 42 facing away from the clamping part 53, the feeding mechanism 3 is provided with two guides 31 at one end near the clamping mechanism 5. Both guides 31 are slidably disposed on the base 1, and the two guides 31 form a rear guide channel 31a between them. The rear guide channel 31a is used to limit the radial position of the heat shrink tube.

[0038] In one embodiment, the feeding mechanism 3 is equipped with two guide members 31 at its discharge end. The movement direction of the two guide members 31 is perpendicular to the axial direction of the thermoplastic tube. The movement trajectory of the thermoplastic tube is adjusted by adjusting the movement of the two guide members 31. A rear guide channel 31a is formed between the two guide members 31. The inner wall of the rear guide channel 31a is clearance-fitted with the thermoplastic tube, thus only guiding and circumferentially limiting the thermoplastic tube, without affecting the normal discharge of the thermoplastic tube. The rear guide channel 31a provides radial support to the heat shrink tube on the back side of the cutting member 42, eliminating long cantilever drooping. The tube is initially limited before entering the clamping member 53, avoiding collision with the edge of the cutter and causing a notch.

[0039] Please see Figure 3 and Figure 4In order to enable the thermoplastic tube material released from the material tray 2 to move smoothly to the target position of the feeding mechanism 3, the feeding mechanism 3 is provided with two guide blocks 32 at one end near the material tray 2. Both guide blocks 32 are located on the base 1, and there is a front guide channel 32a between the two guide blocks 32.

[0040] In this embodiment, two guide blocks 32 are provided at one end of the feeding mechanism 3 near the material tray 2. Both guide blocks 32 are slidably connected to the base 1 by means of a snap-fit ​​or bolt structure, forming a front guide channel 32a between them, thereby guiding the heat shrink tubing released from the material tray 2 into the feeding mechanism 3 for feeding. The guide blocks 32 can be made of aluminum alloy sliders with arc grooves machined on opposite surfaces, or they can be made of antistatic POM plastic as integral protrusions. After the tubing is released from the material tray 2, it is guided by the front guide channel 32a to avoid shaking or deviation, ensuring that it smoothly enters the target position of the feeding mechanism 3. The aluminum alloy arc groove solution has good wear resistance and is suitable for occasions with larger wall thickness or faster feeding speed. The POM slider with rubber column solution is gentle and antistatic, suitable for thin-walled or high-cleanliness tubing. Both of these embodiments improve feeding stability and reduce manual intervention.

[0041] Please see Figure 4 and Figure 6 To prevent the thermoplastic tube from shifting vertically, affecting its normal movement and connection with subsequent structures, the feeding mechanism 3 is provided with a pressing component 34 at one end near the material tray 2. The pressing component 34 includes a rotating shaft 341 and a pressing block 342. The rotating shaft 341 is rotatably mounted on the base 1, and the pressing block 342 is connected to the rotating shaft 341. One end of the pressing block 342 is located in the front guide channel 32a.

[0042] In one embodiment of this application, a horizontal rotating shaft 341 is installed on the base 1 above the two guide blocks 32. The two ends of the rotating shaft 341 are embedded in bearing seats and can rotate freely, while a pressure block 342 is fixedly connected in the middle. The front end of the pressure block 342 extends cantilevered directly above the elastic channel between the two guide blocks 32, maintaining a downward trend by its own weight or the preload of the torsion spring 344, thus forming an upper limiting structure for the heat shrink tubing in the front guide channel 32a. The rotating shaft 341 can be specifically a stainless steel shaft locked to the pressure block 342 with screws, or an aluminum alloy shaft can be used to integrally mill the pressure block 342 to form an integrated "shaft-pressure" component. Both embodiments allow the pressure block 342 to swing slightly around the shaft as the tubing diameter changes, continuously providing downward pressure. The pressure block 342 adds a vertical limiting function to the elastic guide block 32 clamping, preventing the heat shrink tubing from jumping up and down, ensuring that the center height of the tubing is always coaxial with the subsequent rear guide channel 31a and the clamping member 53, avoiding feeding deviation or jamming.

[0043] Please see Figure 4 and Figure 6In order to make the clamping force of the pressure block 342 more stable, the clamping assembly 34 also includes a rotating block 343 and a torsion spring 344. The rotating block 343 is connected to the rotating shaft 341, and the two ends of the torsion spring 344 are connected to the rotating block 343 and the base 1 respectively.

[0044] In this embodiment, the rotating block 343 is sleeved on the outer periphery of the rotating shaft 341 and is keyed or snapped into the rotating shaft 341; the torsion spring 344 is sleeved on the same rotating shaft 341, with one end of the torsion spring 344 hooked on the rotating block 343 and the other end hooked on the preset groove of the base 1, forming a constant torsional preload. The torsion spring 344 continuously applies a constant torque to the pressure block 342 through the rotating block 343, so that the clamping force is not affected by slight changes in the pipe diameter or machine vibration, avoiding the jumping or loosening that may occur with the traditional self-weight pressure block 342, and completely eliminating the vertical offset of the thermoplastic pipe.

[0045] Please see Figure 6 To prevent the pressure block 342 from causing unnecessary damage to the surface of the thermoplastic tube, the end of the pressure block 342 near the base 1 has an abutment portion 3421. The abutment portion 3421 can be provided at the front end of the pressure block 342, while the main body of the pressure block 342 can be a straight structure or a downwardly bent structure. The contact area between the abutment portion 3421 and the heat shrink tube can be provided with a beveled surface forming an angle with the main body of the pressure block 342. The angle of the bevel is adjusted according to the position of the rotating shaft 341. The surface of the abutment portion 3421 is rounded and polished to reduce friction and resistance between the abutment portion 3421 and the thermoplastic tube. The abutment portion 3421 can change the original point contact into line or surface contact, disperse the clamping force, reduce the resistance of the pressure block 342 to the thermoplastic tube, avoid direct pressure of hard metal on the surface of the heat shrink tube, and completely eliminate indentations, scratches, or local thinning; it protects the appearance of the tube while maintaining a stable and reliable clamping function.

[0046] Please see Figure 3 and Figure 4 The feeding mechanism 3 also includes a feeding clamp 33, which is slidably disposed on the base 1 and is used to clamp and drive the pipe to move.

[0047] In one embodiment, the feeding clamp 33 can be two cuboids or have claws on its surface that fit against the outer wall of the heat shrink tubing. The heat shrink tubing is released and clamped by the relative or opposite movement of the two claws. When feeding is required, it is only necessary to control the feeding clamp 33 to move closer to each other to clamp the heat shrink tubing. Then, the whole thing slides relative to the base to move the heat shrink tubing to a preset position. Finally, the two feeding clamps 33 are moved away from each other to complete the feeding process.

[0048] Please see Figure 3 and Figure 4To prevent waste material from the cutting mechanism 4 cutting the thermoplastic tube from entering the clamping parts 53 or the rear guide channel 31a and affecting the quality of the thermoplastic tube product, the tube cutting device 100 includes a waste suction component 6, which is used to absorb the waste material generated by the cutting mechanism 4 cutting the heat shrink tube.

[0049] In this embodiment, the waste suction assembly 6 is arranged close to the cutting mechanism 4, with its suction port aligned with the cutting edge area. The waste suction assembly 6 can use a small vortex fan with a quick-connect hose, and a flat stainless steel suction nozzle is installed at the end of the hose. The suction nozzle is fixed to the side wall of the base 1 and faces the cutting seam. Alternatively, the waste suction assembly 6 can use a factory centralized negative pressure pipeline interface, extending to the cutting point through a PVC rigid pipe. An anti-static nylon funnel is fitted over the pipe opening to form a suction hood. Both solutions instantly remove the debris generated at the moment of cutting. The waste suction assembly 6 removes the pipe chips and dust generated during cutting in the first instance, preventing them from falling into the clamping member 53 or the rear guide channel 31a. This prevents the debris from being clamped again and damaging the surface of the subsequent pipe material, ensuring a clean channel and improving the appearance quality of the finished heat shrink tubing.
