[0002] In the processing and production of plastic products, plastic refers to a material or plastic material product with high molecular weight synthetic resin as the main component, with some additives added to make the processed plastic material shaped into different shapes at will and finally keep the shape unchanged.
[0003] The particle screening device for plastic processing is a widely used equipment in the plastic processing industry. Its main purpose is to separate and screen large particles, impurities or particles of different sizes in the raw materials during the production process of plastic particles.
[0004] The existing plastic particle screening device has shortcomings: on the one hand, a plurality of groups of filter holes are arranged on the surface of the device. When the plastic particles are screened, some plastic particles may have moisture attached to their surface due to the humidity of the stacking ground. When filtering, the moisture may be adsorbed on the filter holes, which may easily cause the filter holes to be blocked, making it impossible to discharge the material, reducing production costs and wasting time. On the other hand, most of the existing screening devices can only screen plastic particles of one size, and cannot accurately screen plastic particles of different sizes, and the practicality is poor. Therefore, a particle screening device for plastic processing is proposed to solve the above problems. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Reference Figure 1-Figure 3The utility model provides an embodiment: a particle screening device for plastic processing, comprising a storage box 1, an outer surface of the storage box 1 is provided with a discharge port 2, through which the material vibrated and screened by the filter box 3 is discharged through the discharge port 2, a vibration component 7 is provided at the top of the storage box 1, the function of the vibration component 7 is to prevent the material from clogging the filter hole of the filter box 3 through strong vibration when screening the material in the filter box 3, the vibration component 7 comprises a support plate 71, the support plate 71 is fixedly connected to both sides of the top of the storage box 1, the top outer wall of the support plate 71 is fixedly connected to a motor 72, the output shaft of the motor 72 is fixedly connected to a rotating shaft 73, the support plate 71 is provided to support the motor 72 and the rotating shaft 73, and the surface center position of the rotating shaft 73 is fixedly connected to an elliptical block 74.
[0031] Reference Figure 2-Figure 4 The top of the storage box 1 is elastically connected to the filter box 3 by a return spring 75, one end of the return spring 75 is fixedly connected to the top of the outer wall of the storage box 1, and the other end of the return spring 75 is fixedly connected to the bottom end of the outer wall of the filter box 3. The return spring 75 acts to squeeze the return spring 75 when the filter box 3 moves downward. When the elliptical block 74 rotates one circle and does not squeeze the connecting plate 6, the filter box 3 moves upward under the rebound force of the return spring 75, and so on, thereby achieving a vibration effect. The inner wall of the filter box 3 is detachably installed with an adjustment plate 4 through a limit assembly 5. The adjustment plate 4 has the same size as the hole opened on the surface of the filter box 3. When pulled out When the position of the filter box 3 remains unchanged while the adjusting plate 4 is in motion, the size of the hole will change and can be adjusted according to the size of the material. The top of the filter box 3 is fixedly connected to a connecting plate 6, and the outer wall of the bottom end of the filter box 3 is fixedly connected to two sets of guide rods 8. The two sets of guide rods 8 slide on the inner wall of the storage box 1 to guide the movement of the filter box 3 to prevent the filter box 3 from swaying left and right during movement. The rotating shaft 73 is rotatably connected to the inner side of the top ends of the two sets of support plates 71, and the outer wall of the elliptical block 74 contacts the outer wall of the connecting plate 6. The rotation of the elliptical block 74 will squeeze the connecting plate 6 and the filter box 3 downward, thereby vibrating the material accumulated on the surface of the filter box 3.
[0032] Reference Figure 3-Figure 5The limit assembly 5 includes a limit rod 51, which is elastically connected to the right inner wall of the filter box 3 through a limit spring 52. One end of the limit spring 52 is fixedly connected to the inner wall of the right side of the filter box 3, and the other end of the limit spring 52 is fixedly connected to the surface of the limit rod 51. The function of the limit spring 52 is that when the limit rod 51 is pulled out of the filter box 3, it is subjected to a compression force of the limit spring 52. When the adjusting plate 4 moves to the required position, the limit rod 51 is subjected to the rebound force of the limit spring 52 and then plugged into the through hole on the right inner wall of the adjusting plate 4. The right inner wall of the adjusting plate 4 is provided with four groups of through holes, and the bottom end of the outer wall of the limit rod 51 is plugged into the inner wall of the through hole. The plugging between the two enables the adjusting plate 4 to be plugged and fixed when it slides to the required position on the inner wall of the filter box 3, so as to fix the position according to the plastic particles of different sizes. The adjusting plate 4 is slidably connected to the inner wall of the filter box 3, and the limit rod 51 passes through and is slidably connected to the right inner wall of the filter box 3.
[0033] Working principle: pour the material to be screened onto the surface of the right side of the filter box 3, and drive the rotating shaft 73 to rotate rapidly through the motor 72. An elliptical block 74 is fixedly connected to the surface of the rotating shaft 73. When the elliptical block 74 rotates, it will squeeze the connecting plate 6 to drive the filter box 3 and the two sets of guide rods 8 fixedly connected to the outer wall of the bottom end of the filter box 3 to descend, and at the same time make the reset spring 75 elastically compressed. When the elliptical block 74 rotates one circle to cancel the squeezing of the connecting plate 6, the filter box 3 returns to the initial state due to the rebound force of the reset spring 75, and the reciprocating motion is like this, so as to achieve a vibration effect on the filter box 3.
[0034] When adjusting the hole size of the filter box 3 according to the size of the material to be screened, the limit rod 51 is pulled out to shrink the limit spring 52, and then the adjustment plate 4 on the inner wall of the filter box 3 is pulled to misalign the holes on the surface of the adjustment plate 4 with the holes on the surface of the filter box 3, so that screening holes of different sizes can be adjusted. Four groups of through holes are provided on the right inner wall of the adjustment plate 4. When the adjustment plate 4 is pulled to the required position, the limit rod 51 is plugged into the through hole on the right inner wall of the adjustment plate 4 under the action of the rebound force of the limit spring 52 to fix it.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
