A polyvinylidene fluoride material crushing and stirring device

Abstract

The present invention relates to the field of crushing and stirring. The present invention discloses a polyvinylidene fluoride material crushing and stirring device. The present invention is composed of a crushing mechanism and a pushing mechanism. In this polyvinylidene fluoride material crushing and stirring device, through the transmission mechanism rotating, two transmission gears inside drive the cross joint and the crushing knives connected to the bottom to rotate. The connected cross joint can make the crushing knives open to both sides while continuously rotating to crush the material. At the same time, the cooperating connected pressing mechanism can make the two crushing knives on both sides move relatively and reversely. Again, in cooperation with the pushing mechanism, the materials around the inner wall of the material bin are rotated through the arc-shaped plate to gather the materials towards the middle. When the two connected crushing knives rotate self-revolvingly and simultaneously perform circumferential crushing, the materials gathered by the arc-shaped plate are contacted and crushed again, enabling the materials around the inner wall of the material bin to contact the crushing knives.

Description

Technical Field

[0001] The present invention relates to the field of crushing and stirring, and specifically relates to a polyvinylidene fluoride material crushing and stirring device. Background Art

[0002] Polyvinylidene fluoride is a highly non-reactive thermoplastic fluoropolymer. During processing, a finished polyvinylidene fluoride material is crushed into particles by a fragmentation device, enabling the material to be better processed and used subsequently.

[0003] The existing patent (Publication No.: CN117400446B) discloses a polyvinylidene fluoride material crushing and stirring device. It includes a housing, a clamping assembly, a crushing mechanism, and a stirring mechanism. The crushing mechanism and the stirring mechanism are both arranged inside the housing, and the crushing mechanism is located above the stirring mechanism. The clamping assembly penetrates the circumferential surface of the housing, and the crushing mechanism penetrates the top of the housing. The outer surface of the stirring mechanism is in rolling connection with the clamping assembly inside the housing. Polyvinylidene fluoride material is put in from the top of the housing, and then the material is crushed by the crushing mechanism. After being crushed into small particle materials, it then drops to the position of the stirring mechanism. The small particle materials in the stirring mechanism are all immersed in water, and the purpose of removing the surface additives of the polyvinylidene fluoride material is achieved through the soaking effect. The clamping assembly is used to assist the rotation of the stirring assembly. Through the rotation of the stirring assembly, the water can be made to rotate, so that the material can be soaked more fully. There are at least the following problems in the prior art that have not been solved: 1. When the crushing knife crushes inside the material bin, the materials placed around the sides are difficult to contact the crushing knife, resulting in the crushing effect not meeting the requirements of the particles and the internal crushing being uneven; 2. When the crushing knife rotates and crushes in the middle, there are still some residual materials below the central axis that cannot be evenly crushed, affecting the efficiency of the equipment for processing and crushing.

At the same time, the fixed column pushes the three-sided plate downward through the sliding column, so that under the hinge action of the movable joint and the central plate, the clamping jaws clamp the materials below, and cooperate with the crushing disc connected to the central transmission shaft to grind and crush the clamped materials, so that the materials below the middle part can also be crushed simultaneously.

[0037] The working principle process of the present invention is as follows:

[0038] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 shown:

[0039] S1: Add large-particle polyvinylidene fluoride materials into the interior of the processing bin 18 through the inlet plate 19. Then, drive the motor 3 to drive the first gear 4 to drive the second gear 5 and the transmission shaft 6 to rotate, so that while the connected large gear 74 rotates on its own, it drives the transmission gear 73 to rotate around the inner wall of the gear ring 75 while rotating on its own. The protruding column 76 and the second concave plate 77 connected to the lower end of the transmission gear 73 drive the first concave plate 82 to rotate through the cross joint 81, so that the rotating column 83 and the crushing knife 85 connected to the lower end of the first concave plate 82 rotate to crush the materials. At the same time, when the output end of the drive motor 3 rotates, it can drive the fitting column frame 15 to rotate, and at the same time drive the rocker column 16 to slide on the inner wall of the groove 17 opened in the large cylinder 13 and the limiting plate 23, and at the same time drive the swing cylinder 14 fixed by the rocker column 16 to perform up-and-down reciprocating motions, so that the right-angle plate 121 and the connecting rod 122 connected to the bottom of the swing cylinder 14 move down and up, push the support rods 124 on both sides of the lower end of the connecting rod 122 to open to both sides, and at the same time push the top column 125 and the sleeve 84 connected to the support rods 124 to both sides, and at the same time move the rotating column 83 and the crushing knife 85 connected to the inside of the sleeve 84 to both sides to crush.

[0040] S2: When the column 83 and the crushing knife 85 rotate simultaneously during central crushing, the connected cylindrical support column 86 can cooperate to push the telescopic rod 87, causing the arc-shaped plate 103 and the material bin 101 to rotate on the inner wall of the processing bin 18. When the two crushing knives 85 move away from each other, while compressing the telescopic rod 87, an angle adjustment is performed, enabling it to slide on the inner wall of the groove formed in the arc-shaped plate 103. This can cooperate with the arc-shaped plate 103 to bring the accumulated material into contact with the crushing knife 85, crushing the material around the inner wall.

[0041] S3: When the stabilizing column 123 moves downward simultaneously, it can push the fixed column 91 downward, causing the fixed column 91 to push the lower triangular plate 97 and the movable joint 94 downward through the sliding column 93. At this time, the connected spring rod 126 starts to compress when the fixed column 91 moves downward. After the fixed column 91 has moved downward by half, the spring rod 126 stops compressing. After the central plate 96 connected to the lower end of the spring rod 126 has moved downward a small distance, the jaws 95 hinged to the movable joint 94 and the central plate 96 grab and crush the large-particle material accumulated on the lower arc-shaped plate 103, enabling the internal crushing disc 98 and the crushing knife 85 to cooperate to crush the material around the perimeter and at the center simultaneously.
