Description

Technical Field

[0001] The utility model relates to the technical field of sand planting devices, in particular to an electrostatic sand planting device. Background Art

[0002] Electrostatic sand implanting device is a device that uses high-voltage electrostatic field force to implant fine abrasive particles on a high-strength film. It is mainly used in the production of coated abrasives. This technology originated in the 1950s and is in contrast to the traditional gravity sand implanting method. During the electrostatic sand implanting process, the abrasive particles are adsorbed on the substrate coated with a binder due to the action of the electric field force, forming an abrasive belt with excellent grinding performance.

[0003] An electrostatic sand implanting device is a device that utilizes high-voltage electrostatic field force to implant fine abrasive particles onto a high-strength film.

[0004] A significant defect in most current electrostatic sand planting devices is the lack of a filtering mechanism. This lack may result in sand particles with diameters exceeding the specified range being sucked into the system during the sand planting process. Such sand particles not only fail to effectively adhere to the substrate, but may also cause uneven sand planting, thereby affecting the quality and performance of the final product.

The lower end of the transport unit 1 is fixedly connected with an electrostatic treatment device 11, wherein the electrostatic treatment device 11 is the prior art composed of an electrostatic treatment box, a conductive rod, and an electrostatic electrode plate.

[0026] In this embodiment, the lifting assembly 5 includes a shell 51 fixedly connected to the transport unit 1, and a first motor 52 is arranged in the shell 51. The shaft end of the first motor 52 is fixedly connected to a threaded rod 53, and a first sleeve 54 is threadedly connected to the threaded rod 53. The upper end of the first sleeve 54 is fixedly connected to the box body 21, and a threaded line is arranged in the first sleeve 54, so that the first sleeve 54 can be driven when the threaded rod 53 rotates, thereby driving the sand falling assembly 2.

[0027] Furthermore, the guide assembly 7 includes a plate 71 fixedly connected to both sides of the frame of the transport unit 1, and a telescopic rod 72 is fixedly connected to the plate 71. The top of the telescopic rod 72 is fixedly connected to the box 21. The two telescopic rods 72 are used to guide the box 21 when it moves up and down, so as to prevent the box 21 from shifting or flipping when moving.

[0028] Among them, the filter assembly 3 includes a shell 31 movably plugged with the box body 21, and a plurality of L-shaped rods 32 are fixedly connected to the shell 31, and a plurality of the other ends of the L-shaped rods 32 are rotatably connected to the lower sides of the Z-shaped rods 33, and a second motor 34 is fixedly connected to the upper end of one of the L-shaped rods 32, and the shaft end of the second motor 34 passes through the L-shaped rod 32 and is fixedly connected to the upper end of the Z-shaped rod 33, and a filter element 6 is fixedly connected to the lower end of the Z-shaped rod 33. When the second motor 34 is started, the Z-shaped rod 33 is driven to rotate eccentrically, so that the filter element 6 is shaken to filter the sand particles, so that large sand particles fall down and small sand particles fall down.

[0029] It should be noted that the filter element 6 includes a filter frame 61 fixedly connected to the lower end of the Z-shaped rod 33, a filter screen 62 movably inserted in the filter frame 61, positioning beads 63 are provided on both sides of the filter screen 62, and holes adapted to the telescopic ends of the positioning beads 63 are opened on both sides of the filter frame 61. When filtering, the positioning beads 63 are stuck in the holes of the filter frame 61, thereby fixing the filter frame 61 and the filter screen 62. When the filter screen 62 needs to be removed for cleaning, the positioning beads 63 can be pressed to remove the filter screen 62.

[0030] On the basis of the above embodiment, the fixing assembly 4 includes a fixing member 41 and a locking member 42;

[0031] The fixing member 41 is fixedly connected to the upper side of the box body 21, a fixing rod 43 is fixedly connected to the fixing member 41, and a ball plunger 44 is provided on the upper side of the fixing rod 43;

When the outer shell 51 needs to be removed, the ball plunger 44 is pressed to pick up the outer shell 51.

[0033] Working method: When working, install the filter screen 62 into the filter frame 61 and fix it with the positioning bead 63, align the hole of the locking piece 42 with the fixing rod 43, and then press and pass the chamfer at the lower end of the locking piece 42 to make the telescopic end of the ball head plunger 44 contract. After passing through the locking piece 42, the telescopic end of the ball head plunger 44 extends out and is locked on the upper side of the locking piece 42. Then, adjust the height according to the size of the sand-planting mold as needed, turn on the first motor 52 to rotate the threaded rod 53, and drive the first sleeve 54 to move up and down. When the first sleeve 54 moves up and down, it will move with the sand falling assembly 2. When it reaches the appropriate height, turn off the first motor 52, and then turn on the second motor 34. The Z-shaped rod 33 is driven to rotate by the second motor 34. The eccentric rotation of the Z-shaped rod 33 causes the filter 6 to shake, and then the sand particles are poured into the filter frame 61.
