Manufacturing device and method of tennis ball processing block, and product

Abstract

The invention relates to a manufacturing device and method of a tennis ball processing block, and a product. The manufacturing device comprises a rolling machine, an inlet combination part, a drying machine and a block cutting machine; after a plurality of machining raw materials are put into the rolling machine from the rear of the rolling machine, the raw materials are pressed by the rolling machine to form a flat shape; the plurality of flat processing raw materials continue to move forwards and are further pressed by the inlet combination part, so that the processed raw materials of different materials are pressed to form a mixed material with an obvious layered structure to enter the drying machine to be dried; and after being dried, the mixed material enters the block cutting machineto be cut into a plurality of block-shaped tennis ball processing blocks. According to the manufacturing device, the different materials are pressed to be combined with each other while the physicalproperty of the materials is maintained; and meanwhile, the pressing process does not need to soak the materials in a zinc stearate solution which is harmful to the environment, and therefore the manufacturing device is relatively safe for the environment and a worker.

Description

technical field [0001] The invention relates to a tennis ball semi-finished product and its manufacturing device and method, in particular to a tennis core material before extrusion and its manufacturing device and method. Background technique [0002] There will be an elastic inner core (core) inside the ball game such as tennis or basketball, which can provide the elasticity of the ball so that it can fully bounce when in use; and the production method of this elastic inner core is by A rubber ball formed by bonding the two hemispherical rubbers to each other after extruding the cut rubber block into a hemispherical shape. [0003] see Image 6 Shown, and the method for producing aforementioned bulk rubber in the prior art is as follows: [0004] First, the raw rubber (not shown in the figure) and other processing materials to be added (such as substances that can improve elasticity or water resistance) are squeezed together by machine force and mixed uniformly, and then ...

AI Technical Summary

Problems solved by technology

[0009] First, the zinc stearate used for cooling and viscosity reduction is itself a solution that is harmful to the environment and the human body. Therefore, under the concept of promoting environmental protection and working environment safety, this solution is not suitable for continued use;

[0010] Second, when the user takes out the block mixture soaked in the zinc stearate solution, the weight is not easy to control because the mixture will absorb water. At the same time, if the block mixture is not properly dried, it will be put into the subsequent For the processing machine, the zinc stearate solution may remain on the inside of the processing machine, causing corrosion of the machine;

[0011] Third, the prior art method of cutting the strip mixture relies on the mutual matching between the speed of the extrusion injection machine pushing the strip mixture and the cutting speed of the cutting device, but it is not easy to adjust to an accurate one during actual operation. speed, so it is more inconvenient to operate;

[0012] Fourth, since the extrusion injection machine used in the prior art is a machine with a single inlet and outlet (that is, it has an inlet and an outlet), it is impossible to effectively enter and maintain a specific directionality of multiple materials. Going out to extrude the injection machine, but can only mix all the raw materials uniformly after extrusion, but the uniform mixing method will make the properties of all the additives mixed together, and cannot make different positions of the tennis ball have different properties; another On the one hand, there is a high chance of crushing the processed raw materials to make them lose their original physical properties
