Description

Technical Field

[0001] This utility model relates to the field of heat shrinkable tape processing technology, and in particular to a cutting device for heat shrinkable tape. Background Technology

[0002] Heat shrinkable tape is a strip-shaped material that uses heat shrink technology, primarily for pipeline repair, insulation, and corrosion protection. It is typically made of materials such as polyolefins and polyesters, and undergoes specific processing to allow it to tightly adhere to the pipeline surface when heated, forming a protective layer. Heat shrinkable tape has excellent temperature resistance and corrosion resistance, effectively extending the service life of pipelines. During the production and use of heat shrinkable tape, it needs to be cut using cutting equipment.

[0003] Existing heat shrinkable tape cutting devices cannot effectively compress and fix the heat shrinkable tape on both sides of the cutter during cutting, thus affecting the cutting effect. For example, CN217675957U discloses a heat shrinkable tape cutting device that, by setting up movable blocks, a sliding groove, and a limiting plate, allows for the cutting of heat shrinkable tape. First, the distance between the movable blocks can be adjusted according to the width of the heat shrinkable tape. The operator can move the movable blocks within the sliding groove. When the distance of the heat shrinkable tape roll is adjusted to a suitable level, the movable blocks are centered. Then, the heat shrinkable tape roll is placed inside the second adjusting rod via a movable shaft. The first adjusting rod, second adjusting rod, and fixing pin facilitate adjustment of the tension of the heat shrinkable tape during cutting, and the limiting plate ensures the heat shrinkable tape is laid flat in a horizontal direction.

[0004] While the aforementioned utility model patent allows for the convenient placement of heat shrinkable tapes of varying widths by adjusting the distance between the two movable blocks, and enables the tapes to be laid taut and horizontally, it suffers from a drawback. The tapes cannot be firmly secured during cutting; they rely solely on their own tension. As the cutter moves downwards, the tapes on either side of the cutter are prone to displacement and wobble due to insufficient lateral pressure, especially when cutting thinner or softer tapes. This not only results in uneven cuts, affecting the smoothness and aesthetics of the cut, but also, in practical applications, the uneven edges may compromise the tightness of the tape's fit with the pipe, reducing its repair, insulation, and corrosion protection effects. Consequently, the heat shrinkable tape fails to provide adequate protection, ultimately impacting the pipe's lifespan.

[0005] Therefore, it is necessary to develop a cutting device for heat shrinkable tape to address the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a cutting device for heat shrinkable tape, which can press and fix the heat shrinkable tape during the cutting process and flatten the heat shrinkable tape, avoiding displacement and shaking of the heat shrinkable tape during the cutting process, improving the flatness and aesthetics of the cutting cut, and improving the cutting quality.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a cutting device for heat shrinkable tape, including a processing table, a cutting component, and a flattening and pressing component. Two first support plates are slidably connected to one end of the top surface of the processing table, and a roll of heat shrinkable tape is rotatably connected to the top of the first support plates. Two second support plates are fixedly connected to the other end of the top surface of the processing table, and a horizontal plate is fixedly connected to the top of the two second support plates. The cutting component is disposed between the two second support plates. The flattening and pressing component includes a movable frame, both ends of which are slidably connected to the outer walls of the two second support plates. A flattening plate is rotatably connected to both ends of the movable frame. One end of a tension spring is fixedly connected to the side wall of each end of the flattening plate, and the other end of the tension spring is fixedly connected to the outer wall of the movable frame. First telescopic members are fixedly connected to the outer walls of the two second support plates, and the telescopic ends of the first telescopic members are fixedly connected to the movable frame.

[0009] Furthermore, a sliding groove is formed on the top surface of the processing table along its width direction, and a bidirectional lead screw is rotatably connected in the sliding groove. A slider is threaded onto both the positive and negative thread sections of the bidirectional lead screw. The two sliders are respectively fixedly connected to the two first support plates. A motor is fixedly connected to one end of the processing table, and the output end of the motor is coaxially fixedly connected to one end of the bidirectional lead screw.

[0010] Furthermore, the cutting assembly includes a movable plate that is slidably connected between the inner walls of the two second support plates. A second telescopic member is fixedly connected to the top surface of the horizontal plate. The telescopic end of the second telescopic member passes through the horizontal plate and is fixedly connected to the movable plate. A cutting tool is fixedly connected to the bottom surface of the movable plate.

[0011] Furthermore, a vertically arranged guide rod is fixedly connected to the top of the movable plate, and sliding holes adapted to the guide rod are opened at both ends of the horizontal plate, and the guide rod is slidably connected to the sliding holes.

[0012] Furthermore, two parallel pressure plates are fixedly connected to the bottom surface of the movable frame, and the two pressure plates are located on both sides of the cutter.

[0013] Furthermore, the first telescopic component and the second telescopic component are specifically adopted as one of an electric push rod, an electric cylinder, and a hydraulic cylinder.

[0014] Furthermore, a flattening roller is rotatably connected to the bottom end of the flattening plate, and the flattening roller is horizontally arranged along the length of the flattening plate.

[0015] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0016] This invention utilizes a flattening and clamping assembly. A first telescopic component drives a movable frame to move downwards along the outer wall of a second support plate until the flattening plate contacts the surface of the heat shrinkable tape to be cut on the processing table. As the first telescopic component continues to drive the movable frame downwards, the flattening plate, under the elastic force of a tension spring, applies a vertical clamping force to the heat shrinkable tape, ensuring its stability on the processing table. Simultaneously, as the movable frame moves further downwards, the flattening plate rotates around its pivot point with the movable frame, causing the bottom ends of the two flattening plates to move in opposite directions. This stretches the heat shrinkable tape to both sides, achieving a flattening operation on the processing table, preventing displacement and swaying of the heat shrinkable tape during cutting, improving the flatness and aesthetics of the cut, and enhancing the quality of the cut.

[0021] The core of this utility model is to provide a cutting device for heat shrinkable tape, which can press and fix the heat shrinkable tape during the cutting process and flatten the heat shrinkable tape, avoiding displacement and shaking of the heat shrinkable tape during the cutting process, improving the flatness and aesthetics of the cutting cut, and improving the cutting quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. 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] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] In one specific embodiment of this utility model, such as Figure 1 As shown, the assembly includes a processing table 1, a cutting component, and a flattening and pressing component. Two first support plates 2 are slidably connected to one end of the top surface of the processing table 1, and heat shrinkable tape rolls 3 are rotatably connected to the top of the first support plates 2. Two second support plates 4 are fixedly connected to the other end of the top surface of the processing table 1, and a horizontal plate 5 is fixedly connected to the top of the two second support plates 4. The cutting component is disposed between the two second support plates 4. The flattening and pressing component includes a movable frame 6, with both ends of the movable frame 6 slidably connected to the outer walls of the two second support plates 4. Flattening plates 7 are rotatably connected to both ends of the movable frame. One end of a tension spring 8 is fixedly connected to the side wall of both ends of the flattening plate 7, and the other end of the tension spring 8 is fixedly connected to the outer wall of the movable frame 6. First telescopic members 9 are fixedly connected to the outer walls of the two second support plates 4, and the telescopic ends of the first telescopic members 9 are fixedly connected to the movable frame 6.

[0025] In one specific embodiment of this utility model, such as Figure 1 As shown, a slide groove 10 is provided on the top surface of the processing table 1 along its width direction. A bidirectional lead screw 11 is rotatably connected in the slide groove 10. A slider 12 is threaded onto the positive and negative thread sections of the bidirectional lead screw 11. The two sliders 12 are fixedly connected to the two first support plates 2 respectively. A motor 13 is fixedly connected to one end of the processing table 1. The output end of the motor 13 is coaxially fixedly connected to one end of the bidirectional lead screw 11.

[0026] The motor 13 drives the bidirectional lead screw 11 to rotate. Due to the action of the positive and negative thread sections of the bidirectional lead screw 11, the two sliders 12 will move towards or away from each other along the slide groove 10, thereby causing the two first support plates 2 to move closer or further apart. In this way, the distance between the two first support plates 2 can be adjusted according to the different widths of heat shrinkable tape rolls 3, so that the equipment can adapt to heat shrinkable tape rolls of different specifications and improve the versatility of the equipment.

[0027] In one specific embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the cutting assembly includes a movable plate 14, which is slidably connected between the inner walls of two second support plates 4. A second telescopic member 15 is fixedly connected to the top surface of the horizontal plate 5. The telescopic end of the second telescopic member 15 passes through the horizontal plate 5 and is fixedly connected to the movable plate 14. A cutter 16 is fixedly connected to the bottom surface of the movable plate 14.

[0028] The telescopic movement of the second telescopic member 15 causes the moving plate 14 to slide up and down between the two second support plates 4, thereby causing the cutter 16 to move up and down. When it is necessary to cut the heat shrinkable tape, the second telescopic member 15 extends, pushing the cutter 16 downward to cut the heat shrinkable tape; after the cutting is completed, the second telescopic member 15 retracts, causing the cutter 16 to rise and reset, preparing for the next cutting.

[0029] Specifically, a vertically arranged guide rod 17 is fixedly connected to the top of the movable plate 14, and sliding holes 18 adapted to the guide rod 17 are opened at both ends of the horizontal plate 5. The guide rod 17 is slidably connected to the sliding holes 18.

[0030] The guide rod 17, in conjunction with the sliding hole 18, provides guidance for the up-and-down movement of the moving plate 14. During the up-and-down movement of the moving plate 14 driven by the second telescopic member 15, the guide rod 17 slides within the sliding hole 18, ensuring the stability and straightness of the moving plate 14's movement. This, in turn, ensures that the cutter 16 can accurately cut the heat-shrinkable tape, improving the precision and quality of the cutting.

[0031] Specifically, the bottom surface of the movable frame 6 is fixedly connected to two parallel pressure plates 19, which are located on both sides of the cutter 16.

[0032] When the moving frame 6 is driven to descend by the first telescopic component 9, the pressure plate 19 descends along with the moving frame 6 and comes into contact with the heat shrinkable tape. When the cutter 16 performs the cutting operation, the pressure plate 19 can press and fix the heat shrinkable tape on both sides of the cutter 16 to prevent the heat shrinkable tape from shifting or shaking during the cutting process, thereby ensuring the flatness and aesthetics of the cut and improving the cutting effect.

[0033] Specifically, the first telescopic member 9 and the second telescopic member 15 are respectively adopted as one of electric push rod, electric cylinder and hydraulic cylinder.

[0034] In one specific embodiment of this utility model, such as Figure 2 As shown, a flattening roller 20 is rotatably connected to the bottom end of the flattening plate 7, and the flattening roller 20 is set horizontally along the length of the flattening plate 7.

[0035] The moving frame 6 is driven to descend by the first telescopic component 9. When the spreading plate 7 comes into contact with the heat shrinkable tape, the spreading roller 20 rolls on the heat shrinkable tape as the spreading plate 7 rotates. The rolling of the spreading roller 20 reduces the friction between the spreading plate 7 and the heat shrinkable tape, making the spreading process smoother. At the same time, it can better spread the heat shrinkable tape, improve the flatness of the heat shrinkable tape, and create good conditions for subsequent cutting operations.

[0036] Working Principle: When using this heat shrinkable tape cutting device, firstly, according to the width of the heat shrinkable tape roll 3, start the motor 13. The motor 13 drives the bidirectional lead screw 11 to rotate, adjusting the two first support plates 2 to a suitable distance, and then install the heat shrinkable tape roll 3 on the first support plate 2. Next, pull the heat shrinkable tape from the heat shrinkable tape roll 3 and place it on the processing table 1. Start the first telescopic component 9, which extends, driving the moving frame 6 to descend. The unfolding plate 7, under the action of the tension spring 8, contacts the heat shrinkable tape and applies pressure. Simultaneously, the flattening roller 20 rolls to flatten the heat shrinkable tape, and the pressure plate 19 presses and fixes the heat shrinkable tape on both sides of the cutter 16. Then, start the second telescopic component 15, which extends, pushing the moving plate 14 and the cutter 16 downwards to cut the heat shrinkable tape. After cutting, the second telescopic component 15 retracts, causing the cutter 16 to rise and reset, and the first telescopic component 9 retracts, causing the moving frame 6 to rise and reset, ready for the next cutting operation.

[0037] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
