[0019] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0020] Example: See Figure 1-3 , a high-efficiency PET glitter preparation ultrafine grinding equipment, comprising a bottom plate 1, the top of which is provided with a multiple grinding structure;

[0021] The multi-crushing structure includes: an operating box 2, two feeding pipes 3, a cutting frame 4, a motor 5, a cutting blade 6, two conveying pipes 7, a crushing assembly and a speed change connection assembly;

[0022] The operating box 2 is fixedly installed on the upper end of the base plate 1, and the two feeding pipes 3 are respectively embedded in the two sides of the upper end of the operating box 2. The cutting frame 4 is installed in the operating box 2 and is connected to the lower ends of the two feeding pipes 3. The motor 5 is fixedly installed at the center of the upper end of the operating box 2. The cutting knife 6 is movably embedded in the cutting frame 4 and is connected to the driving end of the motor 5 at the center of the upper end. The upper ends of the two conveying pipes 7 are respectively connected to the lower ends of the cutting frame 4. The crushing assembly is installed at the lower end of the operating box 2 and is connected to the lower ends of the two conveying pipes 7. The speed change connection assembly is installed at the center of the operating box 2.

[0023] When preparing PET glitter by crushing, the staff first moves the device to the designated position, supports the device through the bottom plate 1, then powers on the device, and feeds the glitter raw material into the operating box 2 through the two feeding pipes 3. The built-in motor 5 drives the cutting knife 6 to rotate in the cutting frame 4. When the raw material enters the cutting frame 4, the cutting knife 6 performs a preliminary crushing operation on the raw material. Then, the raw material that has been preliminarily crushed enters the crushing assembly through the conveying pipe 7. Under the action of the speed change connection assembly, the crushing assembly rotates with the cutting knife 6 to further crush the glitter raw material.

[0024] In the specific implementation process, the crushing assembly includes: a crushing frame 8, a screen plate 9, a crushing shaft 10 and a plurality of crushing knives 11;

[0025] The crushing frame 8 is fixedly installed at the lower end of the operating box 2, the screen plate 9 is fixedly installed at the lower end of the crushing frame 8, one end of the crushing shaft 10 is movably embedded in the screen plate 9, and several crushing knives 11 are respectively installed at the upper end of the crushing shaft 10 and the inner wall of the crushing frame 8.

[0026] When preparing glitter, the raw materials that have been preliminarily crushed and transported through the conveying pipe 7 fall into the crushing frame 8. Under the transmission action of the speed change connection assembly, the crushing shaft 10 in the crushing frame 8 rotates at a high speed. Under the action of several crushing knives 11 and the screen plate 9, the glitter raw materials are finely crushed. The raw materials with particles larger than the screen plate 9 remain in the crushing frame 8, and the glitter is fully crushed.

[0027] In a specific implementation, the speed change connection assembly includes: a mounting plate 12, a transmission shaft 13, a driving gear 14, a driven gear 15 and two transmission gears 16;

[0028] The mounting plate 12 is fixedly installed in the operating box 2, the top of the crushing shaft 10 is movably embedded in the center of the mounting plate 12, the transmission shaft 13 is movably embedded in one side of the mounting plate 12, the driving gear 14 is fixedly installed at the lower end of the crushing knife 11, and the driven gear 15 is fixedly installed at the upper end of the crushing shaft 10. Two transmission gears 16 are respectively installed at the upper and lower ends of the transmission shaft 13, and are respectively engaged with the driving gear 14 and the driven gear 15.

[0029] When the glitter is crushed, the driving gear 14 rotates following the cutting knife 6. Under the meshing action of the driving gear 14 and one of the transmission gears 16, the transmission shaft 13 is driven to rotate. Under the meshing action of the other transmission gear 16 at the lower end of the transmission shaft 13 and the driven gear 15, the crushing shaft 10 is driven. Since the driving gear 14 is larger than the transmission gear 16 at the upper end of the transmission shaft 13 and the transmission gear 16 at the lower end of the transmission shaft 13 is larger than the driven gear 15, the overall rotation speed of the crushing shaft 10 is accelerated, further increasing the crushing efficiency of the glitter.

[0030] During the specific implementation process, a support frame 17 is provided at the connection between the operating box 2 and the base plate 1 .

[0031] During the specific implementation, a fixing bracket 18 is provided at the connection between the motor 5 and the operating box 2 .

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
