Description

Technical Field

[0001] This invention relates to the field of grinding equipment, specifically to a grinding equipment for raw materials of microfiber suede. Background Technology

[0002] Microfiber suede, also known as suede leather or nubuck, is a synthetic leather material made through a special process. It primarily consists of a base fabric made of microfibers coated with a polyurethane (PU) layer. Microfiber suede is highly favored for its unique properties and wide range of applications. Its main functions include: Microfiber suede is similar to natural leather in appearance, feel, and durability, but offers better environmental performance and lower cost, making it a common alternative to natural leather. Due to its delicate suede texture and high-end appearance, microfiber suede is widely used in bags, footwear, clothing, and automotive interiors, significantly enhancing the quality and grade of products. Microfiber suede does not produce harmful substances during production and use, meeting environmental protection requirements. Furthermore, its resistance to bending, abrasion, and aging gives it a long service life. With continuous advancements in manufacturing processes and technology, microfiber suede is becoming more diverse in color, texture, and performance, meeting the needs of different fields and scenarios.

[0003] The raw materials for microfiber suede mainly include basic fiber materials, microfiber, polyurethane resin (PU), and special additives. Therefore, in order to meet the processing requirements, the raw materials usually need to be crushed and ground. However, grinding once may result in poor grinding effect, requiring manual re-grinding of the raw materials after the first grinding, which leads to low grinding efficiency and waste of manpower. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of the embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

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

[0006] Therefore, the purpose of this invention is to provide a raw material grinding device for microfiber suede. When using this device, the raw material for microfiber suede is first fed into the feeding hopper. The raw material flows into the gap between the grinding trough and the intermediate grinding roller. The first motor is turned on to drive the grinding roller to rotate, and the raw material is crushed by the grinding roller. The crushed material flows into the drain 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 tooth, the second bevel tooth, and the second rotating rod to rotate, which in turn drives the horizontal roller and the grinding disc to rotate. There is a small gap between the grinding disc and the drain hole. The crushed material enters this small gap and is ground into finer powder by the grinding disc, then flows into the collection trough and into the conveying pipe, entering the hollow shell. Inside the machine, the second motor is activated to drive the auger rod to rotate, causing the raw material to rise and eventually enter the secondary feeding pipe. Finally, it flows into the feeding hopper, repeating the crushing and grinding process again. This allows some raw materials that have not been completely ground to have a second grinding opportunity, and it replaces manual secondary feeding. In use, the rotating shaft drives the first gear to rotate, which in turn drives the second gear and the round rod to rotate, thereby driving the dispersing blades to rotate. When the raw material of microfiber suede flows out of the feeding hopper a and comes into contact with the rotating dispersing blades, the raw material will be thrown away by the rotating dispersing blades and dispersed around the crushing tank, so that the raw material can be distributed more evenly in the gap between the crushing tank and the crushing roller.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0025] This invention provides a raw material grinding device for microfiber suede. When using this device, the raw material for microfiber suede is first fed into the feeding hopper. 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 crushed material flows along the gap into the drain hole. At this time, the rotating shaft drives the transmission belt and the first rotating rod to rotate, driving the first bevel tooth, the second bevel tooth, and the second rotating rod to rotate, which in turn drives the horizontal roller and the grinding disc to rotate. There is a small gap between the grinding disc and the drain hole. The crushed material enters this small gap and is ground into finer powder by the grinding disc. Then it flows into the collection trough and into the conveying pipe, entering the hollow shell. At this time, the second motor is turned on to drive the auger rod to rotate, causing the crushed material to rise and finally enter the secondary feeding pipe, and finally flow into the feeding hopper, repeating the crushing and grinding process again. This allows some of the raw material that was not completely ground to have a second grinding opportunity, and replaces manual secondary feeding.

[0026] Figures 1-4 The diagram shown is an overall structural schematic of an embodiment of a raw material grinding device for microfiber suede according to the present invention. Please refer to [link / reference]. Figures 1-4 The raw material grinding device for microfiber suede in this embodiment includes a crushing component 100, a grinding component 200 and a secondary feeding component 300.

[0027] The crushing assembly 100 includes a grinding mill housing 110, a crushing trough 120 formed in the inner wall of the grinding mill housing 110, a feeding bin 120a fixed on the outer wall of the grinding mill housing 110 and connected to the crushing trough 120, a crushing trough 120 collection trough 130 formed in the inner wall of the grinding mill housing 110 and communicating with the crushing trough 120, a cover 140 installed on the top of the grinding mill housing 110, a motor frame 150 fixed on the cover 140, a first motor 160 fixed on the motor frame 150, a rotating shaft 170 coaxially connected to the drive end of the first motor 160, and a crushing roller 180 fixed at the bottom end of the rotating shaft 170 and adapted to the crushing trough 120.

[0028] The grinding assembly 200 includes a mounting groove 210 formed in the inner wall of the grinding machine housing 110, a first rotating rod 220 rotatably mounted in the mounting groove 210, a transmission belt 230 with one end sleeved on the rotating shaft 170 and the other end sleeved on the first rotating rod 220, a first bevel tooth 240 fixed at the bottom end of the first rotating rod 220, a second rotating rod 250 rotatably mounted in the mounting groove 210, a second bevel tooth 260 fixed on the second rotating rod 250 and meshing with the first bevel tooth 240, a horizontal roller 270 fixed on the second rotating rod 250, a horizontal plate 280 symmetrically fixed on the inner wall of the mounting groove 210 and symmetrically distributed on the upper and lower sides of the horizontal roller 270, a perforation hole 280a uniformly formed on the horizontal plate 280, and a grinding disc 290 uniformly fixed on the horizontal roller 270 and inserted into the perforation hole 280a, wherein the grinding disc 290 and the inner wall of the perforation hole 280a are at a certain angle.

[0029] The secondary feeding assembly 300 includes a conveying pipe 310 connected to the inner cavity of the collection trough 130, a hollow housing 320 connected to the conveying pipe 310, an auger rod 330 rotatably mounted on the inner wall of the hollow housing 320, a second motor 340 coaxially connected to the outer end of the auger rod 330, and a secondary feeding pipe 350 connected to the outer wall of the hollow housing 320 and located above the feeding bin 120a.

[0030] The device also includes an auxiliary component 400, which includes an L-shaped frame 410 fixed to the outer wall of the grinding machine housing 110, a cylinder 420 fixed to the L-shaped frame 410, and a push plate 430 fixed to the push rod of the cylinder 420. The bottom of the inner wall of the collection trough 130 is set as an inclined surface, and the bottom of the inclined surface is connected to the conveying pipe 310. The L-shaped frame 410 is perpendicular to the inclined surface. The push plate 430 is covered with a rubber sleeve. When in use, the ground raw material falls into the bottom of the collection trough 130. The cylinder 420 is turned on to drive the push plate 430 to move and push the raw material into the conveying pipe 310 to avoid the accumulation of raw material.

[0031] The auxiliary component 400 also includes a first gear 440 fixed on the rotating shaft 170, a round rod 450 rotatably mounted on the cover 140, a second gear 460 fixed on the round rod 450 and meshing with the first gear 440, and a dispersing blade 470 uniformly fixed on the round rod 450. The dispersing blade 470 is located below the discharge port of the feeding bin 120a. In use, the rotating shaft 170 drives the first gear 440 to rotate, which in turn drives the second gear 460 and the round rod 450 to rotate, thereby driving the dispersing blade 470 to rotate. At this time, when the raw material of microfiber suede flows out of the feeding bin 120a and comes into contact with the rotating dispersing blade 470, the raw material will be blown away by the rotating dispersing blade 470 and dispersed around the crushing tank 120, so that the raw material can be distributed relatively evenly in the gap between the crushing tank 120 and the crushing roller 180.

[0032] Combination Figures 1-4 The specific operation of the microfiber suede raw material grinding device according to this embodiment is as follows: When using this device, the microfiber suede raw material is first put into the feeding bin 120a. The raw material flows into the gap between the crushing tank 120 and the middle crushing roller 180. The first motor 160 is turned on to drive the crushing roller 180 to rotate. The raw material is crushed by the crushing roller 180. The crushed raw material flows into the drain hole 280a along the gap. At this time, the rotating shaft 170 drives the transmission belt 230 and the first rotating rod 220 to rotate, driving the first bevel tooth 240, the second bevel tooth 260 and the second rotating rod 250 to rotate, driving the horizontal roller 270. As the grinding disc 290 rotates, a small gap exists between the grinding disc 290 and the drain hole 280a. The raw material fragments enter this small gap and are ground into finer powder by the grinding disc 290. Then, they flow into the collection trough 130 and into the conveying pipe 310, entering the hollow shell 320. At this time, the second motor 340 is turned on to drive the auger rod 330 to rotate, causing the raw material fragments to rise and finally enter the secondary feeding pipe 350. Finally, they flow into the feeding bin 120a, repeating the crushing and grinding process once again. This allows some raw materials that have not been ground to have a second grinding opportunity and replaces manual secondary feeding.
