Description

Technical Field

[0001] The utility model relates to a grinding tool, in particular to a grinding tool for a rubber strip used in a rubber injection machine. Background Art

[0002] Rubber injection machine is a commonly used equipment for producing rubber soles. It is widely used in shoe production lines due to its advantages of high degree of automation, stable production process and high production efficiency.

[0003] The raw material used in the rubber injection machine is usually a long rubber strip. In order to ensure the continuity of the rubber injection machine feeding during shoe production, a large number of rubber strips are usually connected together in sequence to form a long rubber belt. The method of connecting the rubber strips together is as follows: the surface of the existing rubber strips is usually smooth. It is necessary to first grind the connecting ends of the two rubber strips to make the rubber strips expose the sticky part, then overlap the polished parts of the two rubber strips, and finally use a pressing tool to press the overlapping parts so that the two rubber strips can be adhered together. At present, when the rubber strips are actually connected, the file used usually includes a file body with stripe-shaped file patterns and a handle arranged on the file body. When the file is used to grind the rubber strips, the stripe-shaped file patterns have a poor grinding effect on the surface of the rubber strips. The production workers need to repeatedly grind the rubber strips many times to make the rubber strips expose the sticky part. Repeated grinding of the rubber strips requires a lot of physical strength of the workers, which increases the labor intensity of the workers and also seriously affects the work efficiency of connecting the rubber strips. Summary of the invention

[0004] In order to solve the above deficiencies in the prior art, the utility model aims to provide a grinding tool for rubber strips used in a rubber injection machine, so as to reduce the labor intensity of workers and improve work efficiency.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a rubber strip grinding tool for a rubber injection machine, comprising a flat plate, a file plate body relatively fixed on two sides of the flat plate, and a hand-held component fixed on the flat plate; the file plate body is covered with file tooth assemblies with multiple tooth tips.

[0006] As a limitation of the present invention, the file tooth assembly includes a plurality of connecting plates vertically fixed on the file plate body, the plurality of connecting plates are sequentially connected end to end to form a closed loop, and a tooth tip is fixed on each connecting plate.

[0007] As another limitation of the present invention, the file plate body is fixedly connected to the flat plate by screws.

[0008] As a further limitation of the present invention, a hanging hole is provided at the end of the handheld component.

[0009] As a further limitation of the present invention, the file plate body and the file tooth assembly are both made of galvanized sheet material; the flat plate and the hand-held component are both made of wood.

[0010] As a further limitation of the present invention, the flat plate and the handheld component are integrally formed.

[0011] As a third limitation of the present invention, an anti-slip rubber layer is fixedly provided on the outer side of the hand-held component.

[0012] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0013] (1) The utility model adopts a structural form that combines a flat plate, a file plate body, a hand-held component and a file tooth assembly, wherein the file plate body is covered with file tooth assemblies, each of which has a plurality of tooth tips and the tooth tips are relatively sharp. When the utility model is used to grind a rubber strip, the plurality of tooth tips can easily damage the surface of the rubber strip and expose the sticky part of the rubber strip, which can effectively reduce the number of grinding times, thereby effectively reducing the labor intensity of workers and improving the work efficiency of connecting rubber strips.

[0014] (2) The file tooth assembly of the utility model adopts a structural form that combines multiple connecting plates and multiple tooth tips, wherein the multiple tooth tips can increase the grinding effect on the rubber strip and can effectively reduce the number of grinding times. The setting of the connecting plate can increase the space formed between the file tooth assembly and the file plate body, which is conducive to the grinding rubber falling into the space formed between the tooth assembly and the file plate body, and can effectively improve the practicality of the utility model.

[0015] (3) The file plate body of the utility model is detachably connected to the flat plate by screws. When the grinding effect of the file plate body is not good, the file plate body can be easily replaced. In addition, the utility model is provided with a hanging hole. When the utility model is not in use, the hanging hole can be used to hang the utility model, which is conducive to the rational use of the working space and can further improve the practicality of the utility model.

[0016] (4) In the utility model, the file plate body and the file tooth assembly are made of galvanized sheet material, and the flat plate and the hand-held component are made of wood. The galvanized sheet material has high strength, good wear resistance, low cost and is easy to process. Compared with metal materials, wood has a high strength-to-weight ratio, is relatively light in weight and has high strength. This makes the overall weight of the utility model relatively light and the overall strength high, which is convenient for production workers to pick up and use, and also makes the utility model have a long service life.

[0017] (5) The flat plate and the hand-held component of the utility model are integrally formed, which can effectively improve the overall strength of the structure of the utility model. In addition, the hand-held component of the utility model is provided with an anti-slip rubber layer, which not only improves the comfort of use, but also prevents the utility model from falling off the hand during use.

[0018] In summary, the utility model has a simple structure, low manufacturing cost and is easy to use. Each file tooth assembly in the utility model has multiple tooth tips, and the tooth tips are relatively sharp. When the utility model is used to grind a rubber strip, the surface of the rubber strip can be easily damaged and the sticky part of the rubber strip can be exposed, which can effectively reduce the number of grinding times, thereby effectively reducing the labor intensity of workers and improving the work efficiency of connecting rubber strips. The utility model is suitable for grinding rubber strips when connecting rubber strips. BRIEF DESCRIPTION OF THE DRAWINGS
