Description

Technical Field

[0001] The utility model relates to the technical field of tape cutters, and specifically relates to a tape cutter. Background Art

[0002] A tape cutter is specifically used to cut tapes. There is a device at one end for placing the tape, and a blade or saw teeth at the other end for cutting the tape.

[0003] When the existing tape cutter is in use, the tape paper tube is sleeved on the tapered plastic ring, which is convenient for limiting the tape paper tube, and it is convenient for the tape cutter to drive the tape paper tube to rotate, so that the tape is pulled out, and it is convenient to cut the tape with the saw teeth.

[0004] By sleeving the tape paper tube on the tapered plastic ring, in order to ensure that the tape paper tube can rotate normally, it is necessary to ensure that there is a partial gap between the tape paper tube and the tapered plastic ring. When the tape rotates, when the tape paper tube is rolling, the tape will swing left and right and is easy to fall off. Moreover, the gaps between different sizes of tape paper tubes and the tapered plastic ring are different, so the tape paper tube cannot be effectively limited, resulting in the tape paper tube being more likely to fall off. Therefore, we propose a tape cutter. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a tape cutter, which solves the problem that there is a partial gap between the tape paper tube and the tapered plastic ring. When the tape rotates, when the tape paper tube is rolling, the tape will swing left and right and is easy to fall off.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] The embodiment of the present application provides a tape cutter, which solves the problem that there is a partial gap between the tape paper tube and the fixing plastic ring 402. When the tape rotates, the tape paper tube will roll, and the tape will swing left and right and is prone to falling off. It realizes sleeving the tape paper tube on the outer peripheral wall of the tapered plastic ring 5. Through the contact and extrusion between the tapered plastic ring 5 and the tape paper tube, the tape paper tube is limited and fixed, avoiding driving the tape to rotate during work and causing the tape to fall off. By rotating the tapered plastic ring 5 on the outer peripheral wall of the fixing plastic ring 402, the action of the limiting seat 403 prevents the tapered plastic ring 5 from swinging left and right during work, thereby limiting the situation of the tape swinging left and right during work, ensuring the stability of the tape during use, and further avoiding the situation that the tape is prone to falling off. The tapered plastic ring 5 is conical, which is convenient for limiting tape paper tubes of different sizes.

[0024] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0025] The embodiment of the present utility model discloses a tape cutter, according to the attached Figure 1As shown in FIG. -4, it includes a connecting wall 1. A fixed seat 2 is rotatably connected to the outer peripheral wall of the connecting wall 1. A rotating cylinder 201 is rotatably connected to the inner wall of the fixed seat 2. The tape is extruded through the rotating cylinder 201 so that the tape adheres tightly to the object. A contact rod 202 is fixedly connected to the inner wall of the fixed seat 2. The tape is blocked by the contact rod 202 to prevent the tape from sticking to itself. A sawtooth 3 is fixedly installed on the fixed seat 2. The tape is cut by the sawtooth 3. An anti-detachment unit 4, the anti-detachment unit 4 includes a first connecting seat 401 fixedly connected to the connecting wall 1. A fixed plastic ring 402 is fixedly connected to the outer wall of the first connecting seat 401. The tape paper tube is sleeved on the outer peripheral wall of the tapered plastic ring 5. The tapered plastic ring 5 contacts and presses against the tape paper tube to limit and fix the tape paper tube, preventing the tape from rotating when working and causing the tape to fall off;

[0026] A plurality of limiting seats 403 are distributed on the side of the fixed plastic ring 402 away from the first connecting seat 401. The tapered plastic ring 5 rotates on the outer peripheral wall of the fixed plastic ring 402. The limiting groove 404 limits one side of the tapered plastic ring 5. Under the action of the limiting seat 403, the tapered plastic ring 5 is prevented from swaying left and right during work, thereby limiting the situation of the tape swaying left and right during work, ensuring the stability of the tape during use, and further avoiding the situation of the tape being easily detached. The tapered plastic ring 5 is conical, which is convenient for limiting tape paper tubes of different sizes.

[0027] A limiting groove 404 is opened on the inner wall of the fixed plastic ring 402. A tapered plastic ring 5 is sleeved on the outer peripheral wall of the limiting groove 404. A tape roll is sleeved on the tapered plastic ring 5;

[0028] The tapered plastic ring 5 is sleeved on the outer peripheral wall of the limiting groove 404. By sleeving the tape paper tube on the tapered plastic ring 5 and making the inner wall of the tape paper tube contact and press against the tapered plastic ring 5, the tape paper tube is limited.

[0029] The tapered plastic ring 5 is rotatably connected to the outer peripheral wall of the fixed plastic ring 402 through the limiting groove 404. The number of the limiting seats 403 is at least five. Under the action of the limiting groove 404, the tapered plastic ring 5 rotates stably on the fixed plastic ring 402, and the tape paper tube rotates stably on the fixed plastic ring 402.

[0030] A plurality of limiting seats 403 are fixedly connected to the side of the fixed plastic ring 402 away from the first connecting seat 401. Under the action of the limiting seats 403, the rotation of the tapered plastic ring 5 is limited to prevent shaking.

[0031] A plurality of limit seats 403 are equidistantly distributed. Through the plurality of limit seats 403, the limit seats 403 extend along the diameter direction of the fixed plastic ring 402, more effectively limiting the rotation of the tapered plastic ring 5 and avoiding shaking.

[0032] The plurality of limit seats 403 are integrally formed with the fixed plastic ring 402.

[0033] The plurality of limit seats 403 are in contact with one side of the tapered plastic ring 5. The diameter formed on the outer side of the plurality of limit seats 403 is larger than the diameter of the tapered plastic ring 5. By contacting the limit seats 403 with the tapered plastic ring 5, the rotation of the tapered plastic ring 5 is limited, thereby avoiding shaking of the tapered plastic ring 5 during rotation and enabling the tape to rotate stably following the tapered plastic ring 5.

[0034] The side of the first connection seat 401 is flush with one side of the fixed plastic ring 402, and the other side of the fixed plastic ring 402 is flush with the connection wall 1.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
