Description

Technical Field

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

[0002] PET tape is a type of tape made of PET material, commonly used for packaging, binding, and other applications. When applying PET tape, try to keep the tape parallel to the surface of the object being adhered to, avoiding any tilting or twisting forces during the application process. Slowly and evenly press the tape from one end to the other to ensure full adhesion between the tape and the object, expelling air and reducing wrinkles. However, in actual use, if the user holds the tape roll and pulls it out, and the force applied is biased to the side, wrinkles can easily form on the tape, resulting in uneven adhesion. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes an anti-wrinkle PET tape, which more precisely solves the problems described above.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes an anti-wrinkle PET tape, including a PET tape roll. The PET tape roll includes an inner support frame, and a tape tube is rotatably connected to the outside of the inner support frame. Tape is wound around the outside of the tape tube. The inner support frame has two symmetrical and parallel guide rails inside. A slide block is slidably connected to each guide rail. A handle is connected between the two slide blocks. V-shaped frames are fixed on both sides of the handle. The ends of the V-shaped frames extend to the outside of the tape, and a pressure roller is rotatably connected between the outer ends of the two V-shaped frames. The pressure roller makes rolling contact with the outermost layer of the tape.

[0006] Furthermore, the outer wall of the inner support of the tape roll is embedded with a number of ball bearings, and the inner support of the tape roll is connected to the tape drum by the ball bearings.

[0007] Furthermore, the guide rail is a guide rail bar with a "T" cross-section, and the slide block is slidably connected to the guide rail.

[0008] Furthermore, the handle is a curved handle, and the handle is provided with finger grooves.

[0009] Furthermore, the inner support of the tape roll is provided with a support arm, and the support arm is located on the side away from the pressure roller.

[0010] Furthermore, one of the guide rails is provided with a rack portion, and the slide block slidably connected to the guide rail is provided with a limiting component that cooperates with the rack portion.

[0011] Furthermore, the limiting component includes a toothed component, which is connected to the slide block via a torsion spring. The toothed end of the toothed component engages with the tooth groove of the rack portion, and (1043) is installed at the connection position between the torsion spring and the slide block.

[0012] The beneficial effects of this utility model are:

[0013] 1. This utility model allows for pulling by holding the handle, and the slide block, guided by the guide rail, causes the pressure roller at the end of the V-shaped frame to press firmly on the tape outlet position, thereby causing the tape to be pulled out evenly and effectively preventing wrinkles from forming when the tape is pulled out.

[0014] 2. When the handle is held, the slide block slides on the guide rail. Under the action of the toothed part and the rack, the sliding position of the slide block is limited, thereby keeping the pressure roller tightly pressing the tape at the pull-out position. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Example 1

[0021] A wrinkle-resistant PET tape includes a PET tape roll 1. The PET tape roll 1 includes an inner support 101. A tape spool 102 is rotatably connected to the outer side of the inner support 101. Tape 103 is wound around the outer side of the tape spool 102. A plurality of ball bearings 1018 are embedded in the outer wall of the inner support 101, and the inner support 101 is rotatably connected to the tape spool 102 through the ball bearings 1018 to facilitate tape dispensing. The inner support 101 has two symmetrical and parallel guide rails 1011 inside, each guide rail 1011 having... The sliding connection includes a slide block 1012, with a handle 1013 connecting the two slide blocks 1012. V-shaped brackets 1014 are fixed to both sides of the handle 1013, with the ends of the V-shaped brackets 1014 extending to the outer side of the tape 103. A pressure roller 1015 is rotatably connected between the outer ends of the two V-shaped brackets 1014, making rolling contact with the outermost layer of the tape 103. A guide rail 1011 is a T-shaped guide rail strip. The slide block 1012 slides in conjunction with the guide rail 1011, ensuring the stability of the slide block 1012 sliding on the guide rail 1011. In use, by holding the handle 1013 and pulling, the slide block 1012, guided by the guide rail 1011, causes the pressure roller 1015 at the end of the V-shaped bracket 1014 to press firmly against the tape 103's dispensing position, thus evenly pulling the tape 103 out.

[0022] The handle 1013 is a curved handle and has finger grooves. The inner bracket 101 of the tape roll has a support arm 1016, which is located on the side away from the pressure roller 1015, making it convenient to hold and pull the handle 1013.

[0023] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: the present invention allows the tape 103 to be pulled by hand holding the handle 1013, and the slide 1012 is guided by the guide rail 1011, so that the pressure roller 1015 at the end of the V-shaped frame 1014 presses the tape 103 at the glue outlet position, thereby causing the tape 103 to be pulled out evenly under force, effectively preventing wrinkles from forming when the tape 103 is pulled out.

[0024] Example 2

[0025] Because the outermost diameter of the tape 103 will shrink during use, a structure is needed to keep the pressure roller 1015 tightly pressing the tape 103 at the pulled-out position. Therefore, a rack portion 1017 is provided on one of the guide rails 1011, and a limiting component 104 that cooperates with the rack portion 1017 is provided on the slide block 1012 that slides on the guide rail 1011. The limiting component 104 includes a toothed member 1041. 1. A torsion spring 1042 is connected to the slide block 1012. The toothed end of the snap-tooth member 1041 is engaged with the tooth groove of the rack portion 1017. The connection position between the torsion spring 1042 and the slide block 1012 is equipped with 1043. In embodiment 1, when the handle 1013 is held, the slide block 1012 slides on the guide rail 1011. Under the action of the snap-tooth member 1041 and the rack portion 1017, the sliding position of the slide block 1012 is limited.

[0026] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: When the handle 1013 is in action, the slide 1012 slides on the guide rail 1011, and under the action of the toothed member 1041 and the rack portion 1017, the sliding position of the slide 1012 is limited, thereby keeping the pressure roller 1015 pressing tightly against the pull-out position of the tape 103.

[0027] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
