Description

Technical Field

[0001] The present application relates to the technical field of roller tooling, and in particular to an adjustable pressure roller tooling. Background Art

[0002] With the development of modern industry, the demands for connection, fixation and sealing of various equipment, parts and structures are increasing. In many cases, traditional methods such as welding and bolt connection may not be applicable or may not be convenient and efficient enough.

[0003] Industrial tape is easy to operate and quick to use. It can be applied to surfaces of different shapes and materials. It can be used to fix circuits and shield electromagnetic interference in electronic equipment manufacturing; it can be used in the automotive industry for the assembly of body parts and the fixing of wiring harnesses; it can be used in the aerospace field to ensure the connection and sealing of some parts; it can also be used in building decoration, such as fixing insulation materials; in addition, some special-function industrial tapes, such as high-temperature-resistant tapes and anti-static tapes, meet the requirements of specific industrial environments and processes. In general, industrial tape pasting plays an important role in improving production efficiency, reducing costs, and ensuring product quality, and is an indispensable part of modern industrial production.

[0004] Before pasting industrial tape, make sure the surface to be pasted is clean, dry, free of oil and dust, etc., to improve the adhesion of the tape; then, cut the tape to the required length; when pasting, keep pressing the tape on the surface at a constant speed and steadily, and apply appropriate pressure while pasting, so as to enhance adhesion and eliminate bubbles; therefore, if you want to apply industrial tape well, you must apply appropriate pressure when pasting. Applying appropriate pressure has the following advantages:

[0005] 1. Enhance adhesion: Appropriate pressure can promote better contact and infiltration between the adhesive surface and the surface to be adhered, thereby improving the adhesion strength between the tape and the object and ensuring a firm adhesion;

[0006] 2. Remove bubbles: Applying pressure can help remove air bubbles that may exist between the adhesive surface and the adhesive surface, avoiding residual bubbles that affect the adhesive effect and the durability of the tape;

[0007] 3. Evenly distribute the adhesive layer: Spread the adhesive layer more evenly to ensure consistent adhesion in the entire pasting area and avoid poor local adhesion.

[0008] 4. Improve the tightness of the fit: The pressure makes the tape fit closely to the adherend, reducing the gap and enhancing the sealing performance or the stability of the connection.

[0009] Therefore, appropriate pressure is very important, but the prior art commonly uses ordinary uncontrollable pressure rollers, which leads to uncontrollable tape pressure, uneven pressure output, poor tape pasting quality, debonding, etc.

[0010] Some companies in the prior art have improved ordinary pressure-uncontrollable rollers to make the pressure adjustable. For example, in the prior art, an adjustable pressure roller tool with application number: 201920830798.0 discloses a technical solution, including a sleeve structure, both ends of which are open; a sliding portion, which is installed at a first end in the sleeve structure, and the sliding portion can slide axially along the sleeve structure and is restricted from escaping from the first end of the sleeve structure; a roller structure, which is installed on the sliding portion, and at least part of the effective structure of the roller protrudes from the sleeve structure; a pressure regulating structure, which is installed at the second end of the sleeve structure, and the pressure regulating structure The structure includes a pressure regulating cover and a pressure regulating part arranged toward the sliding plate, and the pressure regulating cover can drive the pressure regulating part to slide linearly along the axial direction of the sleeve structure to adjust the distance between the pressure regulating part and the sliding part; a plastic deformation reset device, whose elastic deformation force-bearing ends respectively abut against the pressure regulating part and the sliding part, and provide a reset power to push the sliding part toward the first end of the sleeve structure; a limit device, used to limit the extreme position of the sliding part shrinking into the sleeve structure; the utility model can adjust the force value, and after the force value is selected, the selected force value remains fixed when applied to the product to be tested, and at the same time, the utility model is flexible and light in use and can be applied in a wide range of applications.

[0011] However, this application has the following disadvantages:

[0012] 1. Complex structure; it contains many parts and complex connections, which makes manufacturing difficult, costly, and maintenance cumbersome;

[0013] 2. The adjustment accuracy depends on the operation: the pressure is adjusted by rotating the pressure regulating cover, and the accuracy may be difficult to control accurately. After adjusting the pressure regulating cover, the shell surface needs to give the roller 800 an upward thrust, so that the sliding part 400 moves upward to the limit block 900 and abuts against the lower surface of the limit block 900 to limit the displacement of the sliding part 400. That is, when the roller is used, manual force is still required to achieve the required pressure;

[0014] 3. There is loss in force transmission: When pressure is transmitted through a series of components through multiple components, there is a certain amount of force loss and deviation.

[0015] In summary, it is necessary to provide a new technical solution to solve the above technical problems. Utility Model Content
