Technical Field

[0001] This utility model relates to the field of office supplies technology, and in particular to a tape cutter. Background Technology

[0002] In daily life and industrial production, tape is a commonly used tool for bonding and sealing. As an auxiliary device for using tape, the convenience and functionality of tape cutters are crucial. However, some existing tape cutters, due to their fixed structure, can only be used with tapes of a specific inner diameter. When different sizes of tape are needed, they are often incompatible, resulting in poor equipment versatility. Users need to purchase multiple cutters of different sizes, increasing operating costs.

[0003] Furthermore, existing cutters struggle to maintain the tape's tautness during the tape cutting process, causing it to shift and resulting in uneven cuts that negatively impact performance. Moreover, replacing and maintaining the cutting blades is inconvenient; after prolonged use, the blades become dull, and due to the difficulty of replacement, users may continue to use dull blades, further affecting cutting efficiency and quality.

[0004] Therefore, this application provides a tape cutter to solve the above-mentioned technical problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a tape cutter to solve the problems of existing tape cutters being inconvenient to adapt to multiple specifications of tape, having poor versatility, and the tape being prone to loosening and shifting during cutting, as well as the inconvenience of replacing the cutter.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A tape cutter includes a housing, one end of which is detachably provided with a mounting bracket for mounting a tape body, and the other end is fixed with a receiving part. A cutting part is hinged to the top of the housing at a position corresponding to the receiving part, and a cutting blade is detachably mounted on the cutting part.

[0008] The mounting bracket has a semi-circular structure and is horizontally inserted into the housing. A movable cylinder is rotatably mounted in the middle of the mounting bracket, and an abutment block for abutting against the inner wall of the tape body is elastically mounted on the surface of the movable cylinder.

[0009] Optionally, the end of the housing away from the receiving part is provided with an opening for the mounting bracket to be horizontally inserted, and both the upper and lower ends of the mounting bracket are fixed with insert plates in the inner wall of the horizontal insertion opening.

[0032] like Figure 1-4 As shown, an embodiment of this utility model provides a tape cutter, including a housing 1. The housing 1 is made of high-strength plastic material, has an overall rectangular shape, and a smooth surface that is comfortable to hold and does not easily scratch the user. One end of the housing 1 has a detachable mounting bracket 5 for mounting the tape body 7, and the other end has a receiving part 2. The end of the housing 1 away from the receiving part 2 has an opening for horizontal insertion of the mounting bracket 5. The mounting bracket 5 has a semi-circular structure, and both the upper and lower ends of the mounting bracket 5 are fixed with insert plates 501 that are horizontally inserted into the inner wall of the opening, so that the mounting bracket 5 can be stably inserted and installed in the housing 1.

[0033] A vertical plate 502 is fixed to one side of the mounting bracket 5, with its top extending to the central axis of the mounting bracket 5. A movable cylinder 6 is rotatably mounted on the top side of the mounting bracket 5, allowing it to rotate freely. Positioning ears 101 are fixed to both sides of the housing 1, corresponding to the ends of the movable cylinder 6. Each positioning ear 101 has a round hole. A positioning shaft 8, for penetrating the movable cylinder 6, is inserted between the two positioning ears 101. One end of the positioning shaft 8 has a threaded portion and a fastening cap 801 is threaded into it.

[0034] At least four mounting slots 601 are evenly distributed around the surface of the movable cylinder 6. Each mounting slot 601 contains an abutment block 602 made of rubber, which has elasticity and friction. A spring 603 is fixed inside the mounting slot 601 to elastically abut the abutment block 602 outward. Under the action of the spring 603, the abutment block 602 can extend outward from the mounting slot 601 to abut against the inner wall of the tape body 7. When installing tape bodies 7 with different inner diameters, the abutment block 602 can automatically adjust its extension length according to the size of the inner diameter of the tape body 7 under the action of the spring 603, thereby achieving adaptation to tape bodies 7 with different inner diameters and strong versatility.

[0035] Additionally, the receiving part 2 at the other end of the housing 1 is integrally formed with the housing 1. A first roller 201 is rotatably mounted on the top of the receiving part 2, allowing it to rotate freely. A cutting part 3 is hinged to the top of the housing 1 at the position corresponding to the receiving part 2. A torque spring is provided at the hinge position between the top of the housing 1 and the cutting part 3. The torque spring provides a certain elastic force, keeping the cutting part 3 open relative to the receiving part 2 when no external force is applied, so that the adhesive tape can be pulled out from between the two.

[0036] Meanwhile, a second roller 301 is rotatably mounted on the lower end of the cutting section 3. The second roller 301 has the same structure as the first roller 201 and can rotate freely at the lower end of the cutting section 3. A cutting blade 4 is detachably mounted on the cutting section 3. Specifically, the cutting blade 4 can be installed on the lower end face of the cutting section 3 by horizontal insertion and is located between the first roller 201 and the second roller 301. When it is necessary to replace the cutting blade 4, it can be replaced and maintained simply by pulling it out horizontally, which is convenient.

[0037] The working principle provided by this utility model is that, in actual use, the tape cutter first places the tape body 7 onto the movable cylinder 6. As the contact block 602 on the surface of the movable cylinder 6 abuts against the inner wall of the tape body 7 under the action of the spring 603, the tape body 7 is stably installed on the movable cylinder 6.

[0038] Subsequently, the mounting bracket 5 is horizontally inserted into the opening 102 of the housing 1, so that the insert plate 501 is fully inserted into the inner wall of the opening 102. Then, the positioning shaft 8 is passed through the two positioning ears 101 and the movable cylinder 6, and the fastening cap 801 is tightened to fix the positioning shaft 8. Then, the tape body 7 is installed inside the housing 1.

[0039] When using the tape, pull the tape out from the tape body 7 and pass it between the first roller 201 and the second roller 301 to tighten the tape. When cutting the tape, press down on the cutting part 3 to make the cutting blade 4 cut the tape. Because the tape is taut, the cutting process is more efficient and neat. When the cutting blade 4 becomes dull after a period of use, simply pull it out horizontally to replace it with a new blade, which helps to keep the blade sharp and ensure the cutting effect.

[0040] In summary, this device can be adapted to tape bodies 7 with different inner diameters for installation and use. In addition, it can efficiently cut the pulled-out tape during use and facilitates later maintenance, resulting in good overall performance.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0042] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
