Technical Field

[0001] The utility model belongs to the technical field related to screen processing, and particularly relates to an automatic screen blocking clearing device. Background Art

[0002] The screen is different from general mesh products. It has a strict series of mesh sizes and is a mesh product approved by industries, institutions, and standards that can grade and screen object particles. When the screen is in use, it will become clogged due to long-term use, so a corresponding clearing device is required.

[0003] However, the existing clearing device, when in use, will affect the clearing efficiency because it cannot ensure the quick and effective automatic clearing work. At the same time, when the clearing structure is in use, the surface of the clearing structure is easily worn and a lot of dirt will remain. Therefore, it cannot be quickly replaced and cleaned without the function of disassembling it. To this end, we provide a screen automatic clearing device to solve the above problems.

[0027] The operation process of this embodiment is as follows: through the setting and use of the above-mentioned structure, when it is necessary to clear the blockage on the upper end surface of the screen body 1, the motor 3 can be controlled to work, thereby the motor 3 directly drives the lead screw 401 to rotate, and the lead screw 401 controls the movable plate 5 to slide along the side of the screen body 1, and thereby drives the cleaning plate 2 to move at the upper end surface position of the screen body 1, and then the cleaning plate 2 will scrape the upper end surface of the screen body 1 to clear the blockage, and at the same time, when the cleaning plate 2 needs to be replaced, the movable plate 6 can be moved, thereby the movable plate 6 will drive the abutment block 601 to move the rod in the opposite direction away from the cleaning plate 2, and then the abutment block 601 will directly drive the assembly rod 602 to disengage from the internal position of the assembly hole 201, so that the cleaning plate 2 can be disassembled and replaced. Embodiment 2

[0028] See also Figure 1 and Figure 4 On the basis of the first embodiment, the movable plate 5 is limited by the positioning rod 701 to ensure the stability of the movement of the cleaning plate 2, thereby improving the stability of the blockage clearing.

[0029] Specifically, a U-shaped plate 7 is fixed to the left end surface of the screen body 1 , a positioning rod 701 is fixed to the front and rear end surfaces inside the U-shaped plate 7 , and the movable plate 5 located on the left side of the screen body 1 is slidably mounted on the positioning rod 701 through a sleeve 501 .

[0030] The operation process of this embodiment is as follows: the other end of the cleaning plate 2 is sleeved on the positioning rod 701 through the movable plate 5, so when the cleaning plate 2 moves, the cleaning plate 2 will drive the movable plate 5 on the left side of the screen body 1 to slide along the positioning rod 701, and at the same time, the positioning rod 701 limits the movable plate 5, so that the cleaning plate 2 can slide stably. Embodiment 3

[0031] See also Figure 4 and Figure 5 On the basis of the first embodiment, the spring 605 pushes the adjustment block 603 so that the assembly rod 602 can be stably inserted into the assembly hole 201.

[0032] Specifically, a movable frame 502 is fixed to the upper end surface of the movable plate 5, each movable plate 6 is slidably connected to the upper end surface of the movable frame 502, the left and right end surfaces inside the movable frame 502 are fixed with limiting rods 503, and the lower end surface of the movable plate 6 is fixed with adjusting blocks 603 that slide in the internal position of the movable frame 502, and the end surfaces of the adjusting blocks 603 are penetrated by limiting holes 604, each adjusting block 603 is slidably mounted on the limiting rod 503 through the set limiting holes 604, and the adjusting block 603 is at an end position away from the abutting block 601, and the end surfaces of the adjusting blocks 603 relative to the abutting block 601 are fixed with springs 605, and the springs 605 are slidably mounted on the limiting rods 503 respectively.

[0033] The operation process of this embodiment is as follows: when controlling the movable plate 6 to slide at the upper end surface position of the movable frame 502, the movable plate 6 will drive the adjustment block 603 to slide at the internal position of the movable frame 502, thereby the adjustment block 603 will compress the spring 605, and thereby the movable plate 6 drives the assembly rod 602 to move out of the assembly hole 201 through the abutment block 601. At the same time, when the movable plate 6 is moved, the spring 605 at this time will push the adjustment block 603 to reset, and thereby control the abutment block 601 to reset, so that the assembly rod 602 is reinserted into the assembly hole 201.
