Description

Technical Field

[0001] This utility model relates to the field of adhesive tape technology, and in particular to an easy-tear adhesive tape. Background Technology

[0002] Adhesive tape consists of two parts: a substrate and an adhesive. It is used to bond two or more unconnected objects together. Adhesive tape is often used when packing items, and it is necessary to tear the tape.

[0003] For example, Chinese patent application CN202420438741.7 discloses an easy-tear tape, the specific content of which is as follows: Multiple rectangular limiting blocks are fixed inside the tape body, and a rectangular limiting groove adapted to the rectangular limiting blocks is opened inside the circular embedded tube. The tape body and the circular embedded tube are slidably connected through the cooperation of the rectangular limiting blocks and the rectangular limiting groove. The tape body is moved to the outside of the circular embedded tube, and then the tape sealing cap is fixed to the tape shell. When the tape is needed, the tape body can rotate inside the tape shell, allowing the tape to move between the vertical cutting blade and the longitudinal baffle. When the tape moves to a certain position, two circular pressing parts are pressed with a finger, causing the two circular pressing parts to move towards a square that is close to each other. At this time, the rigid spring is in a contracted state. This presents the following technical problems:

[0004] The existing tape does not have a limiting groove in the middle fixing ring. When using the above structure, a groove that matches the circular embedded tube needs to be opened on the paper core in the middle of the tape body, which is quite cumbersome. It can be seen that the above structure is quite cumbersome in limiting the tape body. Utility Model Content

[0005] To address the cumbersome operation of the tape body limiting mechanism in the prior art mentioned in the background section, this utility model provides the following technical solution:

[0006] An easy-tear tape includes a tape stopper for limiting the tape body;

[0007] The tape limiter includes a housing, and a protrusion on the left side of the housing facilitates tearing of the tape.

[0008] An inner bearing ring is installed inside the outer shell, and an outer bearing ring for limiting the tape roll is installed outside the inner bearing ring. Multiple arc-shaped blocks are installed at the front end of the outer bearing ring, and multiple protrusions are installed on the outer wall of the arc-shaped blocks to facilitate fixing the tape roll. An extrusion member for controlling the expansion of the multiple arc-shaped blocks is sleeved on the front end of the inner bearing ring.

[0009] Furthermore, a side cover is installed at the front end of the housing, a guide roller for guiding the tape is installed on the left side of the inner cavity of the housing, an opening is provided at the front end of the housing, a limit block is installed on one side of the groove of the opening, and a semi-circular pressure block is installed on the left side of the housing to facilitate the compaction of the tape.

[0010] Furthermore, the extrusion member includes a central disc, and a plurality of connecting blocks II are mounted on the outer wall of the central disc. One end of each connecting block II is equipped with a pressure ring for pushing the outer ring of the bearing.

[0011] Furthermore, the central part of the central plate has a deep groove and a shallow groove.

[0012] Furthermore, the front end of the bearing inner ring is provided with multiple limiting grooves for the sliding of the connecting block 2, a fixing plate is installed in the middle of the bearing inner ring, a connecting rod is installed in the middle of the front end of the fixing plate, and a spring for pushing the middle disc is sleeved on the outside of the connecting rod.

[0013] Furthermore, one end of the connecting rod is movably connected to a connecting block, the front end of the connecting block has a slot, and the rear end of the connecting block has a protrusion that slides in the deep and shallow slots.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention, through the arrangement of multiple arc-shaped blocks and protruding spikes, facilitates the limiting of the paper tube core of the tape, allowing the paper tube core and the outer ring of the bearing to rotate synchronously. The arrangement of the outer and inner rings of the bearing ensures smooth rotation of the paper tube core, reducing the likelihood of rotational obstruction. Furthermore, when tearing the tape body, it is only necessary to rotate the outer shell counterclockwise, allowing the protruding spikes to pierce into the tape body, thus tearing the tape body. The operation is simple and convenient. Attached Figure Description

Detailed Implementation

[0021] The preferred embodiments of this utility model are described in detail below, and a clear and complete explanation is given in conjunction with the accompanying drawings.

[0022] Please see Figures 1-3 This utility model provides an easy-tear tape, including a tape limiter 100 for limiting the tape body 10. The tape limiter 100 includes a housing 110, and a side cover 101 is installed at the front end of the housing 110. The side cover 101 and the housing 110 are connected by a common snap-fit ​​method to facilitate quick installation and removal of the side cover 101. A guide roller 111 for guiding the tape body 10 is installed on the left side of the inner cavity of the outer shell 110. An opening 112 is provided at the front end of the outer shell 110, and the tape body 10 moves from the lower end of the guide roller 111 toward the opening 112. A limiting block 113 is installed on one side of the groove of the opening 112, and the limiting block 113 is located in the inner groove of the outer shell 110. After the tape body 10 is torn, the tape body 10 becomes loose without being pulled. With the setting of the limiting block 113, when the tape body 10 becomes loose, the adhesive surface of the tape body 10 is adhered to the limiting block 113, so that the tape body 10 outside the outer shell 110 will not enter the interior of the outer shell 110, so that the tape body 10 can be pulled when it is used again.

[0023] A semi-circular pressure block 114 is fixedly installed on the left side of the outer casing 110 to facilitate the compaction of the tape body 10. When the tape body 10 is pulled for packaging, the non-adhesive surface of the tape body 10 is in contact with the semi-circular pressure block 114. The semi-circular pressure block 114 compresses the tape body 10, making the adhesive surface of the tape body 10 adhere tightly to the item. Multiple protrusions 115 are fixedly installed on the left side of the outer casing 110 to facilitate tearing the tape body 10. When it is necessary to tear the tape body 10, the tape limiter 100 is flipped so that the protrusions 115 move closer to the tape body 10. After the multiple protrusions 115 pierce the tape body 10, the tape body 10 is torn apart by pulling on the tape limiter 100. The hinge is relatively simple.

[0024] An inner bearing ring 130 is fixedly installed inside the outer casing 110. An outer bearing ring 120 for limiting the tape roll is movably installed outside the inner bearing ring 130. Multiple arc-shaped blocks 121 are fixedly installed at the front end of the outer bearing ring 120. Multiple protrusions 122 for fixing the tape roll are fixedly installed on the outer wall of the arc-shaped blocks 121. The multiple arc-shaped blocks 121 can deform, so that the protrusions 122 are inserted into the paper core in the middle of the tape roll, so that the tape roll can rotate with the outer bearing ring 120, so as to pull the tape body 10.

[0025] The front end of the inner ring 130 of the bearing is fitted with an extrusion member 140 for controlling the expansion of multiple arc-shaped blocks 121. The extrusion member 140 includes a central disc 141, and multiple connecting blocks 142 are fixedly installed on the outer wall of the central disc 141. One end of each connecting block 142 is fixedly installed with a pressure ring 143 for pushing the outer ring 120 of the bearing. The side of the pressure ring 143 near the arc-shaped blocks 121 is arc-shaped and coated with lubricating oil to reduce the friction generated when the arc-shaped blocks 121 rotate, so that the outer ring 120 of the bearing rotates more smoothly. The central disc 141 has a deep groove 144 and a shallow groove 145 in the middle.

[0026] The inner ring 130 of the bearing has multiple limiting grooves 131 at its front end for the connecting block 142 to slide back and forth. A fixing plate 132 is fixedly installed in the middle of the inner ring 130 of the bearing. A connecting rod 133 is fixedly installed in the middle of the front end of the fixing plate 132. A spring 134 for pushing the middle disc 141 forward is sleeved on the outside of the connecting rod 133. A connecting block 135 is movably connected to the front end of the connecting rod 133. A slot 137 is opened in the middle of the front end of the connecting block 135. The connecting block 135 can be rotated by inserting a flathead screwdriver into the slot 137. A protrusion 136 that slides in the deep groove 144 and the shallow groove 145 is fixedly installed at the rear end of the connecting block 135.

[0027] When the tape roll is placed outside the bearing outer ring 120, the slot 137 is rotated, causing the protrusion 136 to slide from the deep groove 144 into the shallow groove 145, thereby pushing the middle disc 141 backward, causing the middle disc 141 to squeeze the spring 134. The pressure ring 143 simultaneously squeezes multiple arc-shaped blocks 121, causing the second protrusion 122 to insert into the middle paper core of the tape roll, so that the paper core can rotate smoothly and pull the tape body 10, so that the non-adhesive surface of the tape body 10 and the bottom of the guide roller 111 are in close contact. The tape body 10 passes through the slot of the opening 112. When tearing the tape body 10, it is only necessary to flip the outer shell 110 counterclockwise, so that the first protrusion 115 pierces into the tape body 10, and the tape body 10 can be torn.

[0028] Based on the above description and accompanying drawings, those skilled in the art can understand and implement this utility model. Furthermore, any non-creative modifications made to this utility model by those skilled in the art without inventive effort are still within the protection scope of this utility model.
