Description

Technical Field

[0001] This utility model relates to the field of tape technology, specifically to a self-cutting, environmentally friendly, high-temperature masking tape. Background Technology

[0002] High-temperature masking tape is mainly used in the electronics industry, with a temperature resistance typically between 120℃ and 260℃. It is commonly used for masking in electroplating, powder coating, baking paint, and for fixing electronic components during manufacturing processes, as well as for masking printed circuit boards and high-temperature treatments. High-temperature masking tape is one of the main products among high-temperature masking tapes. However, existing masking tapes have the following problems when used:

[0003] 1. When cutting with scissors manually, the tape is prone to being skewed and uneven. If too much force is used during the cutting process or the knife is used improperly, it may also damage the cut edge of the tape and affect the adhesive performance of the tape.

[0004] 2. Each time the tape is applied, the release paper needs to be peeled off manually, which is time-consuming and laborious, affecting efficiency. Furthermore, when peeling off the release paper manually, the peeling process may become difficult due to local adhesion of the release paper, and the release paper may even be torn, affecting the normal use of the tape.

[0005] 3. The detached release paper is scattered and piled up, making it impossible to classify and recycle, resulting in resource waste and environmental impact. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a self-cutting, environmentally friendly, high-temperature masking tape.

[0007] The technical solution adopted in this utility model is:

[0008] A self-cutting, environmentally friendly, high-temperature masking tape includes a tape roll, a clamping mechanism, a cutting mechanism, and a paper winding mechanism. The tape roll includes a core and masking tape wound on the core. The masking tape includes a tape body and a release paper layer. The cutting mechanism includes a cutting roller and a cutting blade. The paper winding mechanism includes a paper winding roller. The clamping mechanism includes a first clamping member and a second clamping member. The cutting roller and the paper winding roller are rotatably mounted at one end of the first clamping member and the second clamping member, forming a U-shaped space between them for accommodating the tape roll. The tape roll is rotatably mounted at the other end of the first clamping member and the second clamping member through its core. The cutting roller and the paper winding roller rotate tangentially to pull one end of the masking tape out of the tape roll. The paper winding roller is used to wind the release paper peeled from the masking tape into a roll. The cutting blade cooperates with the cutting roller to cut the tape body after the release paper has been peeled off.

[0009] Furthermore, the first clamping member and the second clamping member have the same structure and are symmetrically arranged. Both include clamping pieces. One end of the clamping piece is provided with a circular boss for rotatably supporting the tape roll, and the other end is provided with a shaft hole for rotatably mounting the cutting roller and the paper roll.

[0010] Furthermore, the circular boss includes an insertion part and a positioning part. The insertion part is in clearance fit with the core, and the positioning part is used to limit the axial movement of the tape roll.

[0011] Furthermore, the paper roll includes a hollow roll body, which has an axially formed groove for passing through the release paper, and roller shafts at both ends of the roll body; the first clamping member and the second clamping member have symmetrically formed elongated shaft holes, and the paper roll is rotatably and slidably installed in the elongated shaft holes through its roller shafts, with one end of one of the roller shafts extending out from the clamping member to form a handle.

[0012] When the release paper is introduced into the roll roll, it enters the hollow roll body through the strip groove and then wraps around the outside of the roll body to achieve the winding and recycling of the release paper; the oblong shaft hole is set so that the roll roll can automatically move towards the center of the tape as the thickness of the release paper increases, thus preserving the rotation space.

[0013] Furthermore, an elastic component is provided inside the oblong shaft hole. The elastic component includes a spring and a pressure block. One end of the spring is connected to the wall of the oblong shaft hole, and the other end is connected to the pressure block. The pressure block radially abuts against the roller shaft of the paper roll.

[0014] The flexible components can improve the stability of the paper roll rotation and maintain the tension of the release paper, so that the release paper adheres tightly to the paper roll surface and wraps around it. The paper roll always rotates tangentially with the cutting roll, ensuring a smooth output of the tape.

[0015] Furthermore, the cutting roller includes a roller body and a roller shaft, the roller shaft being rotatably mounted on a first clamping member and a second clamping member; the cutting blade includes a handle portion and a cutting edge portion, the handle portion being slidably mounted on one side of the cutting roller via a guide rod, and when the cutting blade slides along the guide rod, its cutting edge contacts the roller surface of the cutting roller and cuts the tape.

[0016] During operation, the user pushes the cutting blade along the guide rod to bring the blade close to and eventually contact the tape. The blade cuts the tape as it moves, and the cutting position is usually near the contact point between the tape and the pressure roller. Therefore, the tape is in a flat and compressed state, which helps to achieve a clean, crisp, non-sticky, and tear-free cutting effect.

[0017] Furthermore, the cutting mechanism also includes a first magnet and a second magnet, which are respectively installed at both ends of the guide rod for adsorption and positioning when the cutting blade is not in operation.

[0018] Magnetic positioning ensures the cutting blade remains in a fixed and stable position when not in use, preventing accidental slippage due to vibration or tilting during device movement. Magnets at both ends allow the cutting blade to adhere directly to the magnet at the other end after each cut, eliminating the need to slide back along the guide rod and simplifying operation.

[0019] Furthermore, the cutting mechanism also includes a pressure roller, which is installed on one side of the cutting roller and rotates tangentially to the cutting roller to make the tape body adhere to the cutting roller for cutting.

[0020] To prevent the tape from lifting, shifting, or slipping during cutting, which could lead to incomplete, crooked, or damaged cuts; to ensure neat and reliable cuts and improve cutting quality.

[0021] The beneficial effects of this utility model are:

[0022] 1. By using a paper roll roller to wind and peel off the release paper, the problem of randomly discarding release paper in traditional use is solved, improving cleanliness and efficiency, facilitating the classification and recycling of waste release paper, and improving resource utilization.

[0023] 2. By using the tangential rotation of the winding roller and the cutting roller to pull the tape out of the tape roll, it can be used multiple times after only one peeling of the release paper, improving efficiency while ensuring the bonding quality of the tape.

[0024] 3. With its built-in cutting mechanism, the tape can be neatly cut along its width, achieving a fast and clean tape cutting operation and solving the problems of unevenness, adhesion, or damage to the tape edges caused by manual cutting in traditional use. Attached Figure Description

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See Figures 1-4A self-cutting, environmentally friendly, high-temperature masking tape includes a tape roll 10, a clamping mechanism 20, a cutting mechanism 30, and a paper winding mechanism 40; the tape roll 10 includes a core 11 and a masking tape 12 wound on the core, and the masking tape includes a tape body 112 and a release paper layer 111. The cutting mechanism 30 includes a cutting roller 31 and a cutting blade 32, the paper winding mechanism 40 includes a paper winding roller 41, and the clamping mechanism includes a first clamping member 21 and a second clamping member 22. The cutting roller 31 and the paper winding roller 41 are rotatably mounted at one end of the first clamping member and the second clamping member, forming a U-shaped space between them for accommodating the tape roll 10. The tape roll 10 is rotatably mounted at the other end of the first clamping member 21 and the second clamping member 22 through its core. The cutting roller 31 and the paper winding roller 41 rotate tangentially to pull one end of the masking tape 12 out of the tape roll. The paper winding roller 41 is used to wind the release paper peeled from the masking tape into a roll. The cutting blade 32 cooperates with the cutting roller 31 to cut the tape body after the release paper has been peeled off.

[0031] In specific implementation, the first clamping member 21 and the second clamping member 22 have the same structure and are symmetrically arranged. Both include clamping plates. One end of the clamping plate has a circular boss 211 for rotatably supporting the foam tape roll 23, and the other end has a circular shaft hole for rotatably mounting the cutting roller 31 and an oblong shaft hole 202 for rotatably and slidably mounting the paper roll 41. The clamping plates are made of rigid plastic, thin metal sheet, or composite material with certain rigidity and toughness. In use, the clamping plate's deformation ability can be used to slightly increase the distance between the clamping ends of the two clamping members by hand to install the tape roll. The circular boss includes an insertion part and a positioning part. The insertion part is clearance-fitted with the core to support the free rotation of the foam tape roll; the diameter of the positioning part is larger than that of the core to limit the axial movement of the tape roll.

[0032] The paper roll 41 includes a hollow roll body 411, which has a strip groove 412 axially provided for passing through the release paper. Roller shafts 42 are provided at both ends of the roll body. The paper roll is rotatably and slidably installed in the elongated shaft hole 202 through its roller shaft. One end of the left roller shaft extends out from the first clamping member 21 to form a handle 413.

[0033] The paper winding mechanism 40 also includes an elastic component, which includes a spring 42 and a pressure block 43. The elastic component is installed in an oblong shaft hole 202. One end of the spring 42 is connected to the wall of the oblong shaft hole, and the other end is connected to the pressure block 43. The pressure block 43 abuts radially against the roller shaft of the paper winding roller.

[0034] The cutting mechanism 30 also includes a pressure roller 33, a guide rod 34, and a magnet 35.

[0035] The cutting roller 31 includes a roller body 311 and a roller shaft 312, the roller shaft 312 being rotatably mounted in a circular shaft hole. The pressure roller 33 is rotatably mounted at both ends on a first clamping member and a second clamping member, respectively. The pressure roller 33 is located on the lower right side of the cutting roller 31 and rotates tangentially to the cutting roller. The guide rod 34 is fixed at both ends to the first clamping member and the second clamping member along the axial direction of the cutting roller. In this embodiment, the line connecting the center of the guide rod and the center of the cutting roller is continuously perpendicular to the center of the cutting roller and the center of the paper roll. Furthermore, the guide rod 34 is located in front of the pressure roller 33, allowing the tape body to be cut by the pressure roller adhering to the surface of the cutting roller.

[0036] The cutting blade 32 is perpendicular to the guide rod 34 and radially arranged along the roller body 311. The cutting blade 32 has a handle portion and a cutting edge portion. The handle portion has a through hole that mates with the guide rod. The cross-sectional shape of the guide rod is preferably rectangular to prevent the cutting blade from rotating. The cutting edge needs to contact the tape and generate sufficient shearing force during the cutting process. It is usually made of sharp and strong materials with magnetic properties, such as stainless steel or hard alloy. The cutting edge shape can be straight, beveled, or serrated.

[0037] Two magnets 35 pass through both ends of the guide rod and can be glued and fixed to the clamps of the two clamping parts with adhesive.

[0038] The method of using this application is as follows:

[0039] By manually increasing the distance between the clamping ends of the two clamping parts, the foam tape roll 10 is fitted onto the circular boss 211 through both ends of its core, thus achieving the installation of the tape roll.

[0040] The working method of this application is as follows:

[0041] 1. By manually increasing the distance between the clamping ends of the two clamping members, the tape roll 10 can be freely and rotatably mounted on the first and second clamping members through its core;

[0042] 2. When using, the user pulls the tape out of the tape roll, so that the tape passes through the tangential contact point between the cutting roller and the paper roll.

[0043] 3. During the pull-out process, the user peels the release paper from the tape body, allowing the peeled release paper to pass into the roll roller. The peeled tape body then passes through the tangential contact point between the cutting roller and the pressure roller.

[0044] 4. Turn the handle to make the two rollers rotate and drive the tape to output smoothly. The release paper is wound on the paper roll roller. After the tape body is pulled out to a certain length, the user stops pulling and the sliding cutter cuts the tape body.

[0045] 5. When using it next time, pull out a new tape body directly from the tangential contact point between the cutting roller and the pressure roller, and repeat the operation in step 4.

[0046] After the tape roll 10 is fully unwound and used, remove the clamps on one side. If you manually separate the first and second clamps axially, remove the core and paper roll, replace them with new tape rolls and paper rolls, and reuse them after installation.

[0047] 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 are also within the protection scope of the present utility model.
