[0024] Mounting mechanism 4 includes a cam 41, an arc-shaped groove 42, a rack plate 43, a connecting rod 44, a gear 45, a clamping assembly 46, and a driving assembly 47. The cam 41 is rotatably connected to the middle of the left and right sides inside the fixed frame 1. The arc-shaped grooves 42 are all opened at the front end of the cam 41. The rack plates 43 are all slidably connected to the inside of the mounting groove 3. The connecting rods 44 are all set at the inner end of the rack plates 43. The inner end of the connecting rods 44 is fitted with the vertically adjacent arc-shaped grooves 42 and is slidably connected to the inner wall of the vertically adjacent arc-shaped grooves 42. The gears 45 are rotatably connected to the side of the mounting groove 3 away from the middle of the fixed frame 1. Gears 45 mesh with adjacent longitudinal rack plates 43, providing a basis for quick assembly and disassembly of the primary plate filter. Clamping assemblies 46 are located at the four internal corners of the mounting frame 1. Each clamping assembly 46 includes a fixing block 461, a pressing head 462, and a limiting groove 463. The fixing blocks 461 are located at the front end of the gears 45, and the pressing heads 462 are located at the rear end of the fixing blocks 461. The pressing heads 462 are hemispherical. The limiting grooves 463 are located at the four front corners of the filter frame 2. The outer surface of the pressing heads 462 mates with the rear sidewall of the longitudinally adjacent limiting grooves 463. The rear side of the inclined groove 463 fits together, allowing for quick compression of the filter frame 2. The drive assembly 47 is located on the left and right sides of the interior of the fixed frame 1. The drive assembly 47 includes a knob 471, square posts 472, and square holes 473. The knobs 471 are located on the left and right sides of the interior of the fixed frame 1. The square posts 472 are all located at the front center of the cam 41. The square holes 473 are all located in the center of the inside of the knobs 471. The outer surfaces of the square posts 472 are slidably connected to the inner walls of the longitudinally adjacent square holes 473, providing a basis for the forward and backward movement of the knobs 471 and for driving the cam 41 to rotate. The drive assembly 47 also includes a limiting groove 474. The limiting block 475 and the limiting groove 474 are respectively opened in the middle of the left and right sides of the front end of the fixed frame 1. The limiting block 475 is set in the middle of the outer surface of the knob 471. Both the limiting groove 474 and the limiting block 475 are square. The limiting block 475 is installed in cooperation with the inner wall of the vertically adjacent limiting groove 474. The limiting block 475 is slidably connected to the inner wall of the vertically adjacent limiting groove 474. The knob 471 can be quickly locked by the limiting block 475 and the limiting groove 474. An installation mechanism 4 is provided. By moving the knob 471 back and forth and rotating it, the primary filter can be quickly disassembled and locked, which improves the disassembly and assembly efficiency of the primary filter.
[0025] The working principle of the primary plate filter for cigarette factories provided by this utility model is as follows: When installing the primary plate filter for cigarette factories, first fix the fixing frame 1 inside the pipe to provide a foundation for the disassembly and assembly of the primary plate filter. Then, pick up the filter frame 2, align the guide groove 6 with the guide block 5, and then push the filter frame 2 backward so that the rear end of the filter frame 2 fits against the front end of the rubber pad 8. The limiting frame 7 provides a limit for the backward movement of the filter frame 2. Then, pull the knob 471 forward until the limiting block 475 leaves the inside of the limiting groove 474. At this time, the knob 471 is unrestricted. Rotating the knob 471 drives the square column 472 and the cam 41 to rotate through the square hole 473. As the cam 41 rotates, the arc groove 42 presses against the connecting rod 44. The two connecting rods 44 move outward synchronously, and the rack plate 43 also moves outward, driving the gear 45. As the cam 41 rotates, the fixing block 461 also deflects inward. When the cam 41 rotates 90 degrees, the fixing block 461 also deflects inward by 90 degrees. During this process, the hemispherical extrusion head 462 presses the inclined surface behind the limiting groove 463, causing the filter frame 2 to move backward until the filter frame 2 is tightly fitted with the rubber pad 8. At this time, the primary plate filter is fixed. To prevent loosening, the knob 471 needs to be limited. Moving the knob 471 backward causes the limiting block 475 to move backward until the limiting block 475 is inserted into the limiting groove 474. The friction between the outer surface of the limiting block 475 and the inner wall of the limiting groove 474 prevents the limiting block 475 from moving. At the same time, the square limiting block 475 and the limiting groove 474 limit the knob 471, which can effectively prevent the knob 471 from rotating again, thereby locking the knob 471.
[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
