Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing cutting technology, specifically a cutting device that enables heat shrink tubing to be cut neatly using an adaptive energy. Background Technology

[0002] Heat shrink tubing is a specially made polyolefin heat shrink sleeve with properties such as high-temperature shrinkage, flexibility, flame retardancy, insulation, and corrosion resistance. It is widely used in scenarios such as wire connection, end treatment, solder joint protection, and wire harness marking. During the processing and use of heat shrink tubing, it needs to be cut to a specific length according to actual needs. Therefore, the cutting device is the basic equipment in the heat shrink tubing processing flow.

[0003] Currently, heat shrink tubing is cut by a feeding mechanism that moves the tubing towards the cutting blade, making a cut after each preset distance. Since heat shrink tubing is a flexible tube, if the feeding distance is too long, the tubing may bend. This method cannot achieve multiple blades cutting multiple sections of heat shrink tubing at once, resulting in low cutting efficiency. To overcome these shortcomings, existing technology (Chinese patent application number 202420369518.1, application date 2024-02-28) discloses a heat shrink tubing cutting device, which includes a first spool, a first receiving groove, a first annular groove, and a cutting mechanism. The device, in conjunction with a fixed mechanism, can cut heat shrink tubing and other flexible tubing in a single operation, achieving high cutting efficiency. The second spool increases feeding convenience and prevents feed deviation, further improving cutting efficiency. However, the device cuts the heat shrink tubing while it is wound around the outside of the spool. This axial cutting method causes the cut edge of the heat shrink tubing to tilt, affecting the neatness and flatness of the cut. Furthermore, the device cannot adjust the cutting length of the heat shrink tubing according to production needs, resulting in low flexibility in its use.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing equipment. Therefore, we have proposed an adaptive cutting device that enables neat cutting of heat shrink tubing, which effectively solves the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adaptive cutting device that enables neat cutting of heat shrink tubing, thereby solving the problem that the aforementioned device in the background art cuts the heat shrink tubing when it is wound around the outside of a spool. This axial cutting method causes the cut edge of the heat shrink tubing to tilt, which in turn affects the neatness and flatness of the cut. Furthermore, the aforementioned device cannot adjust the cutting length of the heat shrink tubing according to the corresponding production needs, resulting in low flexibility in the use of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an adaptive cutting device that enables neat cutting of heat shrink tubing, comprising an operating table, wherein the operating table is supported and installed by a support frame at the bottom, and the heat shrink tubing body is wound around the top of the operating table by a take-up roller.

[0007] The bottom of the operating platform is provided with an opening assembly for symmetrically opening the heat shrink tubing body along the end of the operating platform towards the center line. The opening assembly includes electric lead screws on both sides of the bottom of the operating platform, and the two electric lead screws are centrally symmetrical. The outer side of the electric lead screws is threaded with a moving plate, and the close ends of the two moving plates are fixedly connected with positioning posts through staggered convex plates. The positioning posts slide through the grooves to the top of the operating platform.

[0008] The top of the operating platform is equipped with a cutting component for cutting the heat shrink tubing body along the centerline.

[0009] A clamping assembly is also provided on one side of the top of the operating platform for clamping the end of the heat shrink tubing body.

[0010] Preferably, the outer wall of the positioning post is formed with anti-slip patterns distributed along the axial direction to increase the friction between it and the heat shrink tubing body.

[0011] Preferably, the cutting assembly includes a fixed frame fixedly connected to the top of the operating table, a cylinder is fixedly installed on the top of the fixed frame, and a cutting blade is fixedly connected to the bottom output rod of the cylinder, and the cutting blade is located at the end centerline of the operating table.

[0012] Preferably, the top of the cutting blade is fixedly connected with symmetrically distributed guide posts, and the guide posts slide on the top of the fixing frame to provide longitudinal guidance for the cutting blade.

[0013] Preferably, the clamping assembly includes a mounting plate fixedly connected to the top of the operating table, and a pressing rod is elastically provided on the top of the mounting plate by a spring. A flexible pressing block is fixedly connected to the bottom of the pressing rod, and the flexible pressing block presses against the end of the heat shrink tubing body.

[0014] Preferably, the top of the operating platform is formed with a positioning ring below the flexible pressure block, and the positioning ring has a semi-circular structure with an opening vertically upward.

[0015] Preferably, the top two ends of the operating platform are formed with symmetrically distributed guide grooves, and the guide grooves are inclined downward along both ends of the heat shrink tubing body. The two ends of the operating platform are fixedly installed with collection boxes, and the collection boxes are received at the inclined outlet of the guide grooves.

[0016] Compared with the prior art, the beneficial effects of this utility model are: This adaptive cutting device that can cut heat shrink tubing neatly can cut it at equal intervals when the heat shrink tubing body is in a parallel straight line state by coordinating the opening component, the cutting component and the pressing component. This makes the cut perpendicular to the tube wall, thus ensuring the neatness and flatness of the cut. Moreover, by controlling the degree of opening of the heat shrink tubing body, the length of the cut tube segment of the heat shrink tubing body can be adjusted to meet the corresponding production needs, thereby improving the flexibility of the device. The specific contents are as follows: (1) By setting the opening component, the electric screw drives the two rows of positioning columns to open the heat shrink tubing body in parallel and symmetrically along the center line, so that the cut is perpendicular to the tube wall, thus ensuring the neatness and flatness of the cut. Moreover, by controlling the degree of opening of the heat shrink tubing body by the two electric screws, the length of the cut tube segment of the heat shrink tubing body can be adjusted to meet the corresponding production needs, thereby improving the flexibility of the device.

[0017] (2) By setting up the cutting component, the heat shrink tubing body can be cut into multiple segments at equal intervals along the center line simply by controlling the cylinder to drive the cutting blade downward. The operation is quick and the cutting is precise. Furthermore, by setting up the guide post to guide the cutting blade longitudinally, the accuracy of the cutting blade cutting along the center line can be guaranteed.

[0018] (3) By setting up a clamping assembly, a spring is used to provide downward pulling force to the lower pressure rod, so that the flexible pressure block can be pressed tightly against the end of the heat shrink tubing body, so as to avoid displacement of the end when the positioning column opens the heat shrink tubing body and affect the uniformity of opening. At the same time, the end of the heat shrink tubing body is positioned by the positioning ring to ensure that the flexible pressure block can apply force evenly when it is longitudinally clamped, thereby ensuring the stability of the clamping assembly.

[0019] (4) By cooperating with the guide groove and the collection box, after the cutting is completed, the tube section of the heat shrink tubing body can automatically slide down along the guide groove to both ends into the corresponding collection box, so as to achieve the effect of automatic collection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1 , Figure 2 and Figure 4 The present invention provides the following technical solution: an adaptive cutting device that enables neat cutting of heat shrink tubing, including an operating table 1, the operating table 1 being supported and installed by a support frame 2 at the bottom, and the top of the operating table 1 having a heat shrink tubing body 4 wound around it by a take-up roller 3.

[0024] The bottom of the operating platform 1 is provided with an opening assembly for symmetrically opening the heat shrink tubing body 4 along the end of the operating platform 1 towards the center line. The opening assembly includes electric lead screws 5 on both sides of the bottom of the operating platform 1, and the two electric lead screws 5 are centrally symmetrical. The outer side of the electric lead screw 5 is threaded with a moving plate 6, and the close ends of the two moving plates 6 are fixedly connected with positioning posts 7 through staggered convex plates. The positioning posts 7 slide through the groove to the top of the operating platform 1.

[0025] The top of the operating platform 1 is equipped with a cutting component for cutting the heat shrink tubing body 4 along the center line; a clamping component is also provided on one side of the top of the operating platform 1 for clamping the end of the heat shrink tubing body 4.

[0026] In use, two electric screws 5 drive two moving plates 6 to move away from each other, and two rows of positioning columns 7 move synchronously along the slide groove to separate. At this time, the take-up roller 3 automatically unwinds the wire, which can pull the end of the heat shrink tubing body 4 through the two rows of positioning columns 7 in a straight line and fix the end through the clamping assembly. Then, the electric screws 5 drive the two moving plates 6 to move closer, and the two rows of positioning columns 7 can then open the heat shrink tubing body 4 symmetrically along the center line. At this time, the cutting assembly can be started to cut the heat shrink tubing body 4 at equal intervals. Since the heat shrink tubing body 4 is in a parallel straight line state during cutting, the cut can be made perpendicular to the tube wall, thus ensuring the neatness and flatness of the cut. Moreover, by controlling the degree to which the two electric screws 5 drive the moving plates 6 and positioning columns 7 to move synchronously and open the heat shrink tubing body 4, the length of the cut tube section of the heat shrink tubing body 4 can be adjusted to meet the corresponding production needs, thereby improving the flexibility of the device.

[0027] The outer wall of the positioning post 7 is formed with anti-slip patterns distributed along the axial direction to increase the friction between it and the heat shrink tubing body 4, so as to prevent the heat shrink tubing body 4 from shifting longitudinally along the positioning post 7 when the positioning post 7 pulls the heat shrink tubing body 4 open, thus affecting the cutting effect of the cut.

[0028] Example 2: Based on Example 1, please refer to... Figure 3 , Figure 5 and Figure 6 The cutting assembly includes a fixed frame 8 fixedly connected to the top of the operating table 1. A cylinder 9 is fixedly installed on the top of the fixed frame 8, and a cutting blade 10 is fixedly connected to the bottom output rod of the cylinder 9. The cutting blade 10 is located at the end centerline of the operating table 1.

[0029] During cutting, simply control the cylinder 9 to move the cutting blade 10 downwards, and the heat shrink tubing body 4 can be cut into multiple segments at equal intervals along the center line. The operation is quick and the cutting is precise.

[0030] Furthermore, the top of the cutting blade 10 is fixedly connected with symmetrically distributed guide posts 11, and the guide posts 11 slide on the top of the fixing frame 8 to provide longitudinal guidance for the cutting blade 10, thereby ensuring the accuracy of the cutting blade 10 cutting along the centerline.

[0031] Meanwhile, the clamping assembly includes a mounting plate 12 fixedly connected to the top of the operating table 1, and a pressing rod 13 is elastically provided on the top of the mounting plate 12 by a spring. A flexible pressing block 14 is fixedly connected to the bottom of the pressing rod 13, and the flexible pressing block 14 presses against the end of the heat shrink tubing body 4. By setting the clamping assembly, the spring provides a downward pulling force to the pressing rod 13, thereby allowing the flexible pressing block 14 to press tightly against the end of the heat shrink tubing body 4, so as to avoid displacement of the end when the positioning post 7 opens the heat shrink tubing body 4, which would affect the uniformity of opening.

[0032] In addition, a positioning ring 15 is formed on the top of the operating platform 1 below the flexible pressure block 14, and the positioning ring 15 has a semi-circular structure with an opening vertically upward. By setting the positioning ring 15, the heat shrink tube body 4 can be positioned when it is pulled to the bottom of the flexible pressure block 14, so as to ensure that the flexible pressure block 14 can apply force evenly when it longitudinally presses the heat shrink tube body 4, thereby ensuring the stability of the pressing assembly.

[0033] Example 3: Based on Example 2, please refer to... Figure 3 The top two ends of the operating platform 1 are formed with symmetrically distributed guide grooves 16, and the guide grooves 16 are inclined downward along the two ends of the heat shrink tube body 4. The two ends of the operating platform 1 are fixedly installed with collection boxes 17, and the collection boxes 17 are received by the inclined outlet of the guide grooves 16.

[0034] After cutting, the tube segments of the heat shrink tubing body 4 can automatically slide down along the guide groove 16 to both ends into the corresponding collection box 17 to achieve the effect of automatic collection.
