[0024] The following will describe the implementation methods of the present application in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present application applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] Example 1

[0026] Reference Figures 1-6 , this embodiment proposes a particle screening device for plastic box production. By setting a connecting device 5, the problem that the size of the screened plastic particles cannot be adjusted, which affects the quality of the produced products, is solved. The device includes a screening cylinder 1 and a semicircular filter plate 4. The screening cylinder 1 is equipped with a top cover 2. The top cover 2 is provided with a feed port 3 connected to the screening cylinder 1. Four symmetrical groups of support rods 8 are fixedly mounted on the screening cylinder 1. A collecting frame 9 is fixedly mounted on the support rods 8 for collecting unqualified plastic particles. The screening cylinder 1 is equipped with a connecting device 5 for screening plastic particles of different sizes, which is used to replace different semicircular filter plates 4 to achieve the function of screening plastic particles of different sizes.

[0027] The connecting device 5 includes two groups of connecting slots 51 symmetrically opened on the screening drum 1, and semicircular filter plates 4 are slidably installed in the connecting slots 51. Different semicircular filter plates 4 are provided with filter holes of different sizes for screening plastic particles of different sizes. A support frame 52 is fixedly installed on the screening drum 1, and two symmetrical groups of T-slots 53 are opened on both sides of the support frame 52. A T-block 54 used in conjunction with the T-slot 53 is fixedly installed on the semicircular filter plate 4. When installing the semicircular filter plate 4, under the action of the limiting device 6, the semicircular filter plate 4 is aligned with the connecting slot 51 on the screening drum 1 and inserted. At the same time, the T-block 54 on the semicircular filter plate 4 is aligned with the T-slot 53 on the support frame 52 and inserted. The T-block 54 is inserted into the bottom of the T-slot 53, so that the semicircular filter plate 4 is installed in the screening drum 1. By replacing different semicircular filter plates 4, the function of screening plastic particles of different sizes can be achieved, thereby avoiding the situation where the size of the screened plastic particles cannot be adjusted, which affects the quality of the produced products.

[0028] Example 2

[0029] Based on Example 1, the technical solution proposed in Example 1 is used to solve the shortcoming that the size of the screened plastic particles cannot be adjusted, which affects the quality of the produced products. Since the filter plate is slidably installed in the equipment, the filter plate may be misaligned when the equipment is working, affecting the screening efficiency of the plastic particles.

[0030] Reference Figures 1-6 , a limiting device 6 is installed on the support frame 52, and the limiting device 6 includes a limiting groove 61 opened in the support frame 52, a T-shaped plate 62 is slidably installed in the limiting groove 61, and a toothed plate 63 is fixedly installed on the T-shaped plate 62. A gear 64 that meshes with the toothed plate 63 is rotatably installed in the support frame 52, and screws 65 are fixedly installed on both sides of the gear 64. A limiting plug 66 that is threadedly connected to the screw 65 is slidably installed in the support frame 52, and a slot 67 for use with the limiting plug 66 is opened on the semicircular filter plate 4. Two symmetrical sets of fixing rods 68 are fixedly installed in the limiting groove 61, and the fixing rods 68 pass through the T-shaped plate 62 and are slidably connected to it, so that the T-shaped plate 62 moves The spring 69 is sleeved on the fixing rod 68, so that the T-plate 62 can be quickly reset. The moving T-plate 62 drives the tooth plate 63 to move, and the spring 69 is forced to shrink. The tooth plate 63 moves and drives the gear 64 to rotate. The rotation of the gear 64 drives the screw 65 to move in the limit plug 66, so that the limit plug 66 moves into the support frame 52. After the semicircular filter plate 4 is installed, the T-plate 62 is loosened. Under the action of the spring 69, the T-plate 62 is reset, and the limit plug 66 enters the slot 67 on the semicircular filter plate 4, thereby limiting the semicircular filter plate 4 to avoid the dislocation of the semicircular filter plate 4 when screening plastic particles, affecting the screening efficiency.

[0031] Two symmetrical sets of rotating plates 7 are rotatably mounted on the support frame 52, semicircular blocks 71 are fixedly mounted on the rotating plates 7, and two symmetrical sets of limiting frames 72 are fixedly mounted on the screening cylinder 1. Limiting rods 73 are slidably mounted on the limiting frames 72. After screening the plastic particles, the rotating plates 7 are rotated so that the semicircular blocks 71 contact the semicircular filter plates 4 to block the filter holes on the filter plates, and the limiting rods 73 are moved to limit the rotating plates 7, thereby completing the coloring of the plastic particles.
