[0046] like Figure 6 As shown, a powder grinding device with automatic loading and unloading of the present invention is provided with an attraction component 11 on the supporting grinding plate 704, and the attraction component 11 includes an electromagnet 1101 arranged on the supporting grinding plate 704, and a magnet block 1102 matched with the electromagnet 1101 is arranged on the other supporting grinding plate 704. When the electromagnet 1101 is energized, an attraction force is generated on the magnet block 1102, forcing the two supporting grinding plates 704 to be clamped together.

[0047] like Fig. 9As shown, a powder grinding device with automatic loading and unloading of the present invention is provided with a clamping assembly 12 for clamping a rotating gear 404 on a mounting plate 902, and the clamping assembly 12 includes a connecting rod 1201 arranged on the mounting plate 902, and the connecting rod 1201 is L-shaped. A pin 1202 meshing with the rotating gear 404 is provided on the connecting rod 1201, and the thickness of the pin 1202 is greater than the thickness of the rotating gear 404.

[0048] Working principle: During grinding, the material is put into the box body 1 through the feeding port 2. When the sealants of the two springs 1004 are attached to each other, the material is blocked. At the same time, with the support of the two squeezing rollers 402, the material is blocked to prevent the material from freely falling into the box body 1. At this time, the latch 1202 is inserted into the rotating gear 404 to form a clamping connection with the rotating gear 404, preventing the squeezing roller 402 and the shaft 401 from rotating freely.

[0049] The guide channel is adjusted, and the electric push rod 603 is started. The output end of the electric push rod 603 drives the connecting plate 602 to move on the tilting block 601, so that the connecting plate 602 drives the guide plate 604 to move away from the grinding roller 503, and the guide plate 604 drives the scraper 605 to move away from the grinding roller 503, so that the guide channel is expanded, and the supporting grinding plate 704 is always in contact with the scraper 605 to form a sealing effect;

[0050] When loading, start the electric push rod 2 901, the output end of the electric push rod 2 901 drives the mounting plate 902 to move, and the mounting plate 902 drives the connecting gear 1 903, the connecting gear 2 904 and the connecting gear 3 905 to move, and at the same time, the connecting rod 1201 and the latch 1202 move until the connecting gear 2 904 is meshed with the rotating gear 404 and the driving gear 504, the transmission gear 804 is separated from the connecting gear 1 903, and the driving gear 504 is separated from the connecting gear 3 905, that is, the connecting gear 2 904 is in effect, the connecting gear 1 903 and the connecting gear 3 905 are ineffective, and the latch 1202 is separated from the rotating gear 404;

[0051] The motor 501 is started, and the output shaft of the motor 501 rotates clockwise to drive the rotating rod 502 to rotate clockwise, and the rotating rod 502 drives the grinding roller 503 to rotate clockwise. At the same time, the rotating rod 502 rotates to drive the driving gear 504 to rotate clockwise, and the driving gear 504 rotates to drive the connecting gear 2 904 to rotate counterclockwise, forcing the rotating gear 404 to rotate clockwise, so that the other rotating gear 404 rotates counterclockwise, so that the two shafts 401 rotate in opposite directions, forcing the squeezing roller 402 to rotate, so that the squeezing roller 402 roughly grinds the material. Since the squeezing roller 402 rotates, the elastic sealant 403 rotates, so that the squeezing roller 402 releases the material while squeezing the material, so that the material falls continuously; due to the limiting effect of the tilting block 601, the material falls into the guide channel, and due to the expansion of the guide channel, the material falls continuously along the guide channel onto the two supporting grinding plates 704 until the material fills the grinding space;

[0052] When the material is loaded and ground, the guide channel is reduced, and the electric push rod 603 is started in reverse. The output end of the electric push rod 603 drives the connecting plate 602 to move on the tilting block 601, so that the connecting plate 602 drives the guide plate 604 to move close to the grinding roller 503, and the guide plate 604 drives the scraper 605 to move close to the grinding roller 503, so that the guide channel is reduced, and the supporting grinding plate 704 is always in contact with the scraper 605 to form a sealing effect;

[0053] Start the electric push rod 2 901, the output end of the electric push rod 2 901 drives the mounting plate 902 to move, the mounting plate 902 drives the connecting gear 1 903, the connecting gear 2 904 and the connecting gear 3 905 to move, and at the same time makes the connecting rod 1201 and the latch 1202 move, at this time the connecting gear 2 904 is separated from the rotating gear 404 and the driving gear 504, the transmission gear 804 is separated from the connecting gear 1 903, the driving gear 504 is separated from the connecting gear 3 905, and the latch 1202 is separated from the rotating gear 404 and the driving gear 504. The rotating gear 404 is meshed, and the rotating gear 404 and the transmission gear 804 are not working at this time; during grinding, the grinding roller 503 rotates independently, forcing the grinding roller 503 to interact with the two supporting grinding plates 704 to achieve fine grinding of the material until it is ground to a reasonable particle size to form powder. Due to the reduction of the guide channel, a small amount of powder will be attached to the grinding roller 503 when it rotates, and at the same time, the scraper 605 will scrape off the residual material on the grinding roller 503, further reducing the adhesion of the powder on the grinding roller 503;

[0054] When the powder in the grinding space is unloaded, the electric push rod 2 901 is started, and the output end of the electric push rod 2 901 drives the mounting plate 902 to move, and the mounting plate 902 drives the connecting gear 1 903, the connecting gear 2 904 and the connecting gear 3 905 to move, and at the same time, the connecting rod 1201 and the latch 1202 are moved. At this time, the connecting gear 2 904 is separated from the rotating gear 404, the connecting gear 2 904 is meshed with the connecting gear 1 903 and the driving gear 504, the transmission gear 804 is meshed with the connecting gear 1 903, the connecting gear 3 905 is meshed with the driving gear 504 and another transmission gear 804, and the latch 1202 is meshed with the rotating gear 404;

[0055] When unloading, start the motor 501, the output shaft of the motor 501 rotates clockwise to drive the driving gear 504 to rotate clockwise, the driving gear 504 drives the connecting gear 2 904 to rotate counterclockwise, the connecting gear 2 904 drives the connecting gear 1 903 to rotate clockwise, the connecting gear 1 903 drives the transmission gear 804 to rotate counterclockwise, the transmission gear 804 drives the rotating shaft 801 to rotate counterclockwise, the rotating shaft 801 drives the adjusting gear 802 to rotate counterclockwise, the adjusting gear 802 drives the arc rack 803 to move upward, and at the same time the driving gear 504 drives the connecting gear 3 905 to rotate counterclockwise, forcing the other transmission gear 804 to rotate clockwise, so that the other adjusting gear 802 rotates clockwise to drive the other arc rack 803 to move upward , so that under the action of the arc-shaped slide groove 702 and the arc-shaped slider 703, the two supporting grinding plates 704 are separated from each other, and both move upward around the grinding roller 503, so that the grinding space is opened, so that the powder on the supporting grinding plate 704 falls down, and at the same time, the supporting grinding plate 704 moves around the outer ring of the scraper 605. At this time, the scraper 605 scrapes the inner wall of the supporting grinding plate 704 to scrape off the powder on the supporting grinding plate 704, so that the powder falls completely. After the powder in the grinding space falls, it is discharged through the discharge hopper 3, thereby realizing the feeding action, and at the same time, the opening between the two supporting grinding plates 704 is controlled to control the amount of feeding. When the opening is larger, the powder feeding speed is faster, and when the opening is smaller, the powder feeding speed is slower;

[0056] During the grinding process, the grinding roller 503 exerts a force on the supporting grinding plate 704. In order to improve stability, the electromagnet 1101 is powered on. After the electromagnet 1101 is powered on, it generates an attraction force on the magnet block 1102, so that the two supporting grinding plates 704 are integrated to prevent the two supporting grinding plates 704 from rotating and preventing the powder from falling during the grinding process. At the same time, the spring 1004, the supporting outer rod 1001 and the supporting inner rod 1002 are used to provide a supporting effect on the side wall of the supporting grinding plate 704, thereby improving the stability of the supporting grinding plate 704. The stability of the grinding plate 704; before unloading, the electromagnet 1101 is powered off to reduce the attraction between the two supporting grinding plates 704.
