Description

Technical Field

[0001] The utility model belongs to the technical field of adhesive tapes, in particular to a degradable adhesive tape. Background Art

[0002] Adhesive tape is a widely used adhesive product that consists of a substrate and an adhesive applied to one or both sides of the substrate. It uses the intermolecular force of the adhesive to fill the tiny irregularities between objects by applying force, thereby producing an adhesion effect.

[0003] Existing biodegradable tapes can be decomposed by microorganisms in the natural environment after use, thereby reducing pollution to the environment. The tapes are bonded to objects through the adhesive on the inside. However, when using the tapes, due to their strong toughness, they need to be cut with a sharp tool. At the same time, the tapes need to be cut with a sharp tool each time they are used, which makes the use of the tapes cumbersome and time-consuming. Therefore, improvements are needed. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a degradable adhesive tape.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown, the utility model provides a degradable tape, comprising a tape body 1, an inner wall of the tape body 1 is provided with a pressing structure 2, an inner cavity of the pressing structure 2 is provided with a resisting structure 3, and a cutting assembly 4 is provided inside the pressing structure 2 and located on the left side of the resisting structure 3;

[0024] The cutting assembly 4 includes a blade 401, the outer side of the blade 401 is movably connected to the inner wall of the connecting frame 202, and connecting blocks 402 are provided on both sides of the blade 401, and the outer sides of the connecting blocks 402 extend to the outside of the connecting frame 202;

[0025] The pressing structure 2 includes a mounting block 201, the outer side of the mounting block 201 is connected to the inner wall of the tape body 1, the top of the mounting block 201 is movably connected to a connecting frame 202, and a pressing plate 204 is provided on the inner wall of the connecting frame 202;

[0026] When the tape body 1 is in use, the end of the tape body 1 is passed through the pressing plate 204, which drives the pressing plate 204 to move to the other end of the connecting frame 202, and then the extended tape is pasted at the appropriate position, and then the tape body 1 is stretched, so that the tape body 1 is connected to the part that needs to be adhered, and then the connecting block 402 is pressed to drive the blade 401 to cut the extended tape, so that the blade 401 cuts the pasted tape, so that it does not need to be cut manually, which facilitates the operation and use of the tape body 1.

[0027] Among them, the top of the mounting block 201 is connected to a spring 1 203, and the other end of the spring 1 203 is connected to the inner wall of the connecting frame 202;

[0028] The elastic force of the spring 1 203 drives the connecting frame 202 as a whole to always keep the pressing plate 204 in contact with the outer surface of the tape body 1 as the tape is consumed, thereby ensuring the normal use of the blade 401 and the resisting structure 3.

[0029] There are two pressing plates 204, which are respectively arranged on both sides of the resisting structure 3.

[0030] Through the design of the two pressing plates 204, the end of the tape is adhered and pressed on the pressing plate 204 after cutting, so as to prevent the end from sticking to the tape body 1 and requiring re-searching when the tape body 1 is used later, thereby improving the use rate of the tape body 1.

[0031] The support structure 3 includes a movable plate 301, the outer side of the movable plate 301 is movably connected to the inner wall of the connecting frame 202, the bottom of the movable plate 301 is connected to a connecting rod 302, the bottom of the connecting rod 302 passes through the connecting frame 202 and is installed with a pressure block 303;

[0032] When the operator cuts the tape, the pressing block 303 will squeeze the tape between the two pressing plates 204, and then fix the end of the tape through the pressing block 303 to prevent the end from sticking to the tape body 1, making it easier to continue using the tape body 1 later.

[0033] The movable plate 301 is elastically connected to the connecting frame 202 via a second spring 304;

[0034] At this time, since the movable plate 301 is in a stretched state, a downward pressure will be applied to the movable plate 301, which drives the movable plate 301, the connecting rod 302 and the pressure block 303 to move downward. The pressure block 303 squeezes the tape in the two pressing plates 204 to prevent the end of the tape body 1 from resetting and avoids the ends from interlacing with each other, so that there is no need to find the tape head when using it next time, which increases the usage speed.

[0035] The resisting structure 3 further includes a protrusion 305, the outer surface of the protrusion 305 is movably connected to the bottom of the movable plate 301, and a handle 306 is provided on the outer side of the protrusion 305 and located on the outer side of the connecting frame 202;

[0036] By rotating the handle 306, the protrusion 305 is driven to press the movable plate 301, thereby driving the pressing block 303 to move upward as a whole, making it convenient to pass the tape head through the two pressing plates 204, making it easier to cut the tape body 1 and press the end.

[0037] The connecting block 402 is elastically connected to the connecting frame 202 via a spring 3 403;

[0038] After pressing the connecting block 402, the spring 3 403 acts to move the blade 401 upward, thereby facilitating subsequent cutting.

[0039] The tape body 1 is made of polylactic acid, which is a biopolymer produced by fermentation of renewable resources and has good biodegradability and biocompatibility.

[0040] The working principle and use process of this utility model:

[0041] First, when the operator is using the tape body 1, the end of the tape body 1 is found, and then the handle 306 is rotated to drive the protrusion 305 to squeeze the movable plate 301, and the pressing block 303 is moved away from between the two pressing plates 204. Then the end of the tape body 1 passes through the two pressing plates 204 and extends to the outside of the connecting frame 202. At this time, the handle 306 is loosened, and the elastic force of the spring 2 304 drives the movable plate 301, the connecting rod 302 and the pressing block 303 to move downward, squeezing the passed tape. , and then when using the tape body 1, the tape is pulled out from the tape body 1 by pulling the extended tape head, and the tape tension resists the pressure of the pressing block 303 without being hindered, and is used for adhesion between materials. Then, the connecting block 402 is pressed to drive the blade 401 to cut the pulled-out tape, and the tape loses tension, and the pressing block 303 squeezes the tape head again, thereby fixing and cutting the tape head through the pressing block 303 and the blade 401, which increases the use rate of the tape and is simple and convenient to operate.
