Description

Technical Field

[0001] The invention relates to the field of grinding devices, in particular to a raw material grinding device for microfiber suede leather. Background Art

[0002] Microfiber suede, also known as suede microfiber leather or suede, is a synthetic leather material made by a special process. It is mainly composed of microfiber base fabric and coated with a layer of polyurethane (PU) coating on the surface. Microfiber suede is favored for its unique properties and wide application fields. Its main functions include: Microfiber suede is similar to natural leather in appearance, feel and durability, but has better environmental performance and lower cost, so it is often used as a substitute for natural leather. Due to its delicate suede feel and high-end appearance, microfiber suede is widely used in luggage, shoes, clothing and automotive interiors, which can significantly improve the texture and grade of the product. Microfiber suede does not produce harmful substances from production to use, which meets environmental protection requirements. At the same time, its folding resistance, wear resistance and aging resistance make it have a long service life. With the continuous development of production processes and technologies, microfiber suede is more diversified in color, texture and performance, which can meet the needs of different fields and scenarios.

[0003] The raw materials of microfiber suede leather mainly include basic fiber materials, ultrafine fibers, polyurethane resin (PU) and special additives, etc. Therefore, in order to meet the processing needs, the raw materials usually need to be crushed and ground. However, one-time grinding may result in poor grinding effect, and the raw materials after one-time grinding need to be manually put into the grinding device for secondary grinding, resulting in low grinding efficiency and waste of manpower. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0005] In view of the above problems and / or the problems existing in the existing raw material grinding device for microfiber suede leather, the present invention is proposed.

[0006] Therefore, the purpose of the present invention is to provide a raw material grinding device for microfiber suede leather. When using the device, the raw material of microfiber suede leather is first put into the feeding bin, and the raw material flows into the gap between the crushing trough and the middle crushing roller. The first motor is turned on to drive the crushing roller to rotate, and the raw material is crushed by the crushing roller. The raw material fragments flow into the leakage hole along the gap. At this time, the rotating shaft drives the transmission belt and the first rotating rod to rotate, driving the first bevel gear, the second bevel gear and the second rotating rod to rotate, driving the cross roller and the grinding sheet to rotate. There is a small gap between the grinding sheet and the leakage hole. The raw material fragments enter this small gap and are ground into finer fragments by the grinding sheet, and then flow into the collecting trough, and flow into the conveying pipe and enter the hollow shell. In the body, the second motor is turned on to drive the auger rod to rotate, which drives the raw material to rise and finally enter the secondary feeding pipe, and finally flow into the feeding bin, repeating the crushing and grinding process again, so that some raw materials that have not been ground can get the opportunity to be ground again, and replace manual secondary feeding; and when in use, the rotating shaft drives the first gear to rotate, drives the second gear and the round rod to rotate, thereby driving the scattering blades to rotate. At this time, when the raw materials of microfiber suede leather flow out of the feeding bin a and contact the rotating scattering blades, the raw materials will be blown away by the rotating scattering blades and dispersed around the crushing trough, so that the raw materials can be more evenly distributed in the gap between the crushing trough and the crushing roller.
