Description

Technical Field

[0001] This utility model relates to the technical field of adhesive strip application equipment, and in particular to an adhesive strip application device in a groove. Background Technology

[0002] Currently, the application of adhesive strips in narrow grooves is usually done manually. Due to the narrowness of the groove, it is difficult to position the adhesive strip within the groove. Even with the help of some tools, it is impossible to guarantee that the application will not deviate. In addition, during the application process, fingers are usually inserted into the groove to press and ensure that the adhesive strip is firmly attached. However, due to the limited space for finger movement in the narrow groove, the pressure applied is also limited, resulting in extremely unstable quality of the internal adhesive strip application. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a device for applying adhesive strips in a groove, which can complete the positioning and pressing action of the adhesive strip in the narrow groove, thereby improving the quality of adhesive strip application in the groove.

[0004] Technical solution: To achieve the above objectives, the present invention provides a groove-mounting adhesive strip device, comprising a rod body, the end of which includes a limiting end face, the limiting end face being fitted with the groove opening end face of the narrow groove, and a pressing block and a positioning block being fixedly disposed on the limiting end face;

[0005] The groove surface of the narrow groove adhesive strip is the adhesive surface. The end face of the pressing block facing the adhesive surface is provided with a first limiting groove. The end face of the positioning block away from the adhesive surface is provided with a second limiting groove. When the adhesive strip is simultaneously engaged with the first limiting groove and the second limiting groove, the adhesive strip and the limiting end face are parallel to each other.

[0006] Furthermore, when the pressing block presses the adhesive surface of the adhesive strip to adhere to the adhesive surface, the positioning block adheres to the adhesive surface.

[0007] Furthermore, the depth of the second limiting groove is greater than the thickness of the adhesive strip.

[0008] Furthermore, the bottom surface of the second limiting groove is a smooth curved arch surface.

[0009] Furthermore, the surface of the positioning block near the adhesive surface is an arc surface.

[0010] Furthermore, both the pressing block and the positioning block are rotatably provided with positioning bearings on their end faces facing the adhesive surface, and the outer circular surface of the positioning bearings is in contact with the groove end face of the narrow groove.

[0011] Beneficial effects: The groove-mounted adhesive strip device of this utility model has two block structures with limiting slots at the ends of the rod body. These blocks are used to insert the adhesive strip into the groove after it is clamped outside the groove. At the same time, the adhesive strip is guided and limited in the direction of pasting, and the adhesive strip is pressed during the pasting process. This prevents the adhesive strip from deviating during pasting, ensures the firmness and flatness of the adhesive strip, and thus comprehensively improves the quality of adhesive strip pasting in the groove.

[0013] Figure 2 This is a schematic diagram showing the fit between the pressing block and the positioning block, the rubber strip, and the narrow groove. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] As attached Figure 1-2 The aforementioned device for applying adhesive strips in a groove includes a rod 1. The end of the rod 1 includes a limiting end face 11, which is fitted to the groove opening end face of a narrow groove 5. A pressing block 2 and a positioning block 3 are fixedly disposed on the limiting end face 11. The groove surface of the narrow groove 5 for applying the adhesive strip 4 is the adhesive surface 51. The pressing block 2 has a first limiting groove 21 on its end face facing the adhesive surface 51, and the positioning block 3 has a second limiting groove 31 on its end face away from the adhesive surface 51. When the adhesive strip 4 is simultaneously engaged with both the first limiting groove 21 and the second limiting groove 31, the adhesive strip 4 is parallel to the limiting end face 11. The rod 1 can be used as a handle, and the pressing block and positioning block respectively cooperate with two surfaces of the adhesive strip, serving as pressing and fixing functions during the adhesive strip application process. The thickness of both the pressing block and the positioning block should be narrower than the width of the narrow groove 5 so that they can be inserted into the groove to complete the adhesive strip pasting action. The extension length of the two relative to the limiting end face 11 should be shorter than the groove depth of the narrow groove 5 to ensure that the limiting end face can fit with the groove end face and play a guiding role in the pasting process.

[0016] When applying the adhesive strip, first, clamp the adhesive strip to the device. First, clamp one end of the adhesive strip to the first limiting groove 21, ensuring the adhesive side faces the groove opening to facilitate adhesion between the adhesive side and the adhesive surface 51. Then, while straightening the adhesive strip, insert the middle portion into the second limiting groove 31. The adhesive side of the adhesive strip adheres to the bottom surface of the second limiting groove 31, securing the adhesive strip and maintaining its straightness between the two clamping points. Finally, extend the end of the device holding the adhesive strip into the narrow groove until the limiting end face aligns with the groove opening. The adhesive strip is then brought closer to the adhesive surface 51 by the control rod. First, the pressing block 2 presses the strip to adhere one end to the adhesive surface 51. Then, ensuring the limiting end face is in contact with the groove end face, the rod is pulled along the groove to complete the adhesive strip adhesion. During this process, the pressing block 2 applies continuous pressure to ensure the adhesive strip is firmly adhered. The positioning block 3 acts as an isolation point between the adhesive strip and the adhesive surface 51, preventing multiple discontinuous adhesion points and ensuring the adhesive strip is gradually pressed from one end to the other to ensure a smooth adhesion. Simultaneously, the second limiting groove also limits the unattached portion of the adhesive strip, preventing lateral deviation and ensuring the adhesive strip is straight and parallel to the groove opening, significantly improving the adhesion quality within the narrow groove.

[0017] When the pressing block 2 presses the adhesive surface of the adhesive strip 4 against the adhesive surface 51, the positioning block 3 also adheres to the adhesive surface 51. Through the sliding contact between the positioning block 3 and the adhesive surface, it further assists in guiding the sliding and stabilizing the operation. In addition to the original pressing block tightening the adhesive strip, it provides an extra support point, and the line connecting the two support points remains parallel to the adhesive surface. This ensures that when the manual operation lever completes pressing the adhesive strip, the force applied to the adhesive strip by the pressing block is always perpendicular to the adhesive surface, thereby guaranteeing the final bonding quality, facilitating manual operation, and reducing the difficulty of operation.

[0018] The depth of the second limiting groove 31 is greater than the thickness of the adhesive strip 4. This effectively prevents the adhesive strip from slipping out of the groove, ensuring that it continuously restrains the deviation of the adhesive strip during the pasting process and ensuring that the adhesive strip's pasting trajectory does not deviate. In addition, the width of both the first and second limiting grooves is slightly wider than the width of the adhesive strip. This provides a locking effect while minimizing resistance during sliding pasting. The depth of the first limiting groove is less than the thickness of the adhesive strip, so that when the adhesive strip is inserted into the first limiting groove, its adhesive surface is slightly higher than the groove opening. This provides sufficient space for the deformation of the adhesive strip after being pressed, and also avoids direct contact between the pressing block and the groove surface during the pasting process, further reducing the resistance of the sliding operation.

[0019] The bottom surface of the second limiting groove 31 is a smooth, curved arch. This reduces the contact area between the bottom surface of the groove and the adhesive surface of the adhesive strip. While using adhesive force to fix the adhesive strip, it avoids excessive adhesive force that would generate significant resistance and tensile force on the adhesive strip. While keeping the adhesive strip taut between the pressing block and the positioning block, this allows the adhesive strip to easily slide relative to the second limiting groove, making the pasting process smoother. Furthermore, reducing the contact area with the adhesive surface helps minimize the impact on the adhesiveness of the surface, further improving the quality of the pasted product.

[0020] As attached Figure 2 As shown, the surface of the positioning block 3 near the adhesive surface 51 is an arc surface. The curvature change occurs along the groove direction, providing good auxiliary support when positioning the end of the adhesive strip. When inserting the end of the rod with the adhesive strip into the groove, the arc surface of the positioning block 3 can first contact the adhesive surface 51. Then, the adhesive strip end is positioned by sliding along the groove direction. After positioning, while keeping the position of the positioning block 3 unchanged in the groove direction, the rod holding part is rotated. Using the contact surface between the positioning block 3 and the adhesive surface 51 as a fulcrum, the pressing block gradually approaches the adhesive surface, ultimately pressing the end of the adhesive strip to adhere to the adhesive surface, further ensuring the accuracy of the adhesive strip's placement.

[0021] In this embodiment, both the pressing block 2 and the positioning block 3 have rotatably mounted positioning bearings 6 on their end faces facing the adhesive surface 51. The outer circular surface of the positioning bearing 6 is in contact with the groove end face of the narrow groove 5. An improvement to the original structure is made by lengthening the protrusions of the pressing block 2 and the positioning block 3 from the limiting end face 11, providing installation space for the positioning bearings. The line connecting the center points of the rotation axes of the two positioning bearings 6 remains parallel to the limiting end face 11. Thus, the two positioning bearings replace the original positioning and guiding function of the limiting end face, making the adhesive strip application process smoother and the operation more convenient and fluid.

[0022] The above are merely preferred embodiments of this 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 this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
