Detailed Implementation

[0014] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0015] Please see Figures 1-3 This utility model provides a technical solution for an edge trimming mechanism for tab tape: including a driving component 1, an upper blade holder 2, a lower blade holder 3, an adjustment structure 4, and a fixing auxiliary component 5; The drive unit 1 serves as a power output component, used to drive the upper cutter holder 2 to move vertically toward or away from the lower cutter holder 3, providing power for the cutting action. It can be a cylinder or an electric push rod, etc.

[0016] Cutting blades (the type of blade can be adapted according to the characteristics of tape A) are installed at the bottom of the upper blade holder 2 and the top of the lower blade holder 3. The upper blade holder 2 moves downward under the drive of the drive unit 1, and cooperates with the lower blade holder 3 to complete the cutting of the edge material of the tab tape A.

[0017] The adjustment structure 4 is used to adjust the position of the lower cutter holder 3 relative to the upper cutter holder 2, which can achieve fine adjustment in the horizontal direction, ensure precise alignment of the upper and lower cutters, and guarantee cutting accuracy. The adjustment method can be lead screw adjustment, bolt tightening adjustment, etc.

[0018] Among them, the aforementioned drive component 1, upper tool holder 2, lower tool holder 3, and adjustment structure 4 are all existing conventional technologies in the field, and are described in the company's disclosed technologies. Therefore, they will not be described again in this application.

[0019] The fixing auxiliary component 5 is a long strip structure, installed on the downward-facing side of the upper knife holder 2, and its position corresponds to that of the lower knife holder 3. It is a key component for stabilizing the tape A. Preferably, it is made of industrial sponge material, which has a certain elasticity and cushioning performance.

[0020] The fixing auxiliary component 5 has a raised center on one side of the lower blade holder 3, making the cross-section arc-shaped. This arc-shaped structure can form a gradual fit with the surface of tape A from point contact to surface contact before the cutter falls, avoiding excessive local stress on tape A and causing wrinkles.

[0021] The fixing auxiliary component 5 is thickened so that its overall height exceeds the bottom plane of the upper knife holder 2, ensuring that the fixing auxiliary component 5 can contact the tape A and stabilize it before the cutting action begins.

[0022] Furthermore, a groove is provided on the upper tool holder 2 at the position corresponding to the fixing auxiliary component 5, and the width of the groove is greater than the width of the fixing auxiliary component 5. The height of the raised portion in the middle of the fixing auxiliary component 5 is greater than the depth of the groove, ensuring that the raised portion can protrude from the groove and make contact with the tape A.

[0023] The fixing auxiliary component 5 is located in the middle of the groove, and there is a gap between its two sides and the inner wall of the groove. This gap can provide deformation space for the fixing auxiliary component 5 when it is under pressure.

[0024] The fixing auxiliary component 5 has a through mounting hole 51, which consists of an outer hole 511 and an inner hole 512, both coaxial and penetrating the industrial sponge material. The diameter of the outer hole 511 is larger than the diameter of the inner hole 512, and the outer hole 511 faces the side corresponding to the lower tool holder 3. At the same time, the groove of the upper tool holder 2 has a pre-drilled mounting hole 51 corresponding to the position of the mounting hole 51. By inserting bolts, washers, or other hardware components into the mounting hole 51, the fixing auxiliary component 5 can be detachably fixed in the groove of the upper tool holder 2, facilitating future maintenance and replacement.

[0025] Working principle: The position of the lower cutter holder 3 is adjusted by adjusting structure 4 to ensure that the cutter of the lower cutter holder 3 is precisely aligned with the cutter of the upper cutter holder 2, ensuring that the cutting size meets the requirements; at the same time, the installation of the fixing auxiliary component 5 is checked to confirm that its raised part protrudes from the bottom plane of the upper cutter holder 2; the tab tape A is conveyed to the upper cutter holder 3 along the preset path, and the drive component 1 is started to drive the upper cutter holder 2 to move downward; during the downward movement of the upper cutter holder 2, the fixing auxiliary component 5 contacts the tab tape A before the cutter, and its arc-shaped raised structure fits the surface of tape A and applies appropriate pressure to stably press tape A on the lower cutter holder 3 to achieve stability; the upper cutter holder 2 continues to move downward, and the cutter of the upper cutter holder 2 cooperates with the cutter of the lower cutter holder 3 to complete the edge removal.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
