Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this embodiment provides a vibrating screen for the production and processing of plastic particles that facilitates material feeding. It includes a housing 1 with a feed inlet at the top. An adjustable feed assembly 2 is fixedly installed on the top of the housing 1, positioned above the feed inlet. A door 3 is rotatably installed on the front of the housing 1 for easy cleaning and maintenance of the interior. Mounting brackets 8 are fixed on both sides of the inner walls of the housing 1. An aperture-adjustable screening assembly 9 is positioned between the two mounting brackets 8 at different heights, creating a height difference between the two ends of the aperture-adjustable screening assembly 9. This facilitates feeding the plastic particles remaining on the top of the aperture-adjustable screening assembly 9. Discharge outlets are provided on both sides and the bottom of the housing 1, and discharge racks 4 are fixed on both sides of the housing 1.

[0029] The bottom of the box 1 is fixed with a support leg 5, and a spring 10 is fixedly installed at the bottom of the support leg 5. The other end of the spring 10 is fixed with an outer sleeve 6. Under the action of the spring 10, the bottom of the support leg 5 can move up and down inside the outer sleeve 6. The bottom of the box 1 is equipped with a vibration motor 11 and a protective shell 7. The vibration motor 11 is located inside the protective shell 7. The protective shell 7 has a protective effect on the vibration motor 11, and a heat dissipation vent is provided on the outside of the protective shell 7 to handle the heat generated by the vibration motor 11 during operation. Two triangular blocks 12 are fixed on the inner wall of the bottom of the box 1. Under the action of the triangular blocks 12, the plastic particles can quickly flow out through the discharge port.

[0030] One application of this embodiment is as follows: the adjustable feeding assembly 2 can be manually adjusted according to the size and shape of the plastic particles, which facilitates the control of the feeding speed of the plastic particles, ensures that the plastic particles are evenly distributed on the aperture-adjustable screening assembly 9, makes full use of the working area of ​​the screening equipment, and improves the screening effect and efficiency. During screening, the vibration motor 11 is controlled by an external controller. The operation of the vibration motor 11 can drive the box 1 to vibrate, which improves the screening efficiency of plastic particles. In addition, the spring 10 connects the support leg 5 and the outer sleeve 6 together. The spring 10 is equipped with a damper, which enables the spring 10 to reduce the vibration of the box 1 and extend the service life of the internal components of the box 1.

[0031] The box 1 is equipped with two sets of aperture-adjustable screening components 9, which facilitates multi-stage screening of plastic particles. Plastic particles passing through the upper aperture-adjustable screening component 9 fall to the top of the lower aperture-adjustable screening component 9 under their own gravity and are screened again. Plastic particles filtered out by the top of both sets of aperture-adjustable screening components 9 can be discharged through the discharge rack 4, while plastic particles passing through the lower aperture-adjustable screening component 9 flow out through the discharge port at the bottom of the box 1, thus enabling the classified collection of screened plastic particles.

[0032] The adjustable feeding assembly 2 includes a feeding frame 201 and a mounting shaft 202. The bottom of the feeding frame 201 is fixedly installed on the top of the housing 1. An adjustment groove is provided inside the feeding frame 201. Both ends of the mounting shaft 202 are rotatably installed inside the adjustment groove. The mounting shaft 202 can be installed on the top of the adjustment plate 203 to facilitate the adjustment of the angle of the adjustment plate 203. The adjustment plate 203 is fixed on the outside of the mounting shaft 202. A threaded sleeve 204 is fixedly installed on one side of the feeding frame 201. An adjustment screw 205 is threadedly connected inside the threaded sleeve 204. One end of the adjustment screw 205 is installed on one side of the adjustment plate 203, and the other end of the adjustment screw 205 is located on the outside of the feeding frame 201 to facilitate the adjustment operation of the adjustment screw 205.

[0033] In this embodiment, a rotating block is fixed to the other end of the adjusting screw 205. The adjusting screw 205 can be rotated by manually rotating the rotating block. The adjusting screw 205 is threadedly connected to the threaded sleeve 204, which allows the adjusting screw 205 to move and facilitates the rotation of the adjusting plate 203. This allows the size of the feed inlet to be adjusted, controlling the feeding speed of the plastic particles. The plastic particles can be screened on the aperture-adjustable screening component 9 with a suitable flow rate and distribution.

[0034] The aperture-adjustable screening assembly 9 includes a screening plate 901 and a fixing frame 902. The two ends of the screening plate 901 are respectively set inside the two mounting frames 8. The fixing frame 902 is fixed to the bottom of the screening plate 901. Slide grooves are provided on both sides inside the fixing frame 902. An electric push rod 903 is fixed on one side inside the fixing frame 902. A screening plate 904 is fixedly installed on the other end of the electric push rod 903. Limiting plates 905 are fixed on both sides of the screening plate 904. The limiting plates 905 are slidably set inside the slide grooves. The slide grooves have a limiting effect on the limiting plates 905, and the limiting plates 905 improve the stability of the screening plate 904.

[0035] In this embodiment, screening plates 901 and 904 are respectively provided with screening holes 1 and 2. The electric push rod 903 can be stretched to move screening plate 904 below screening plate 901, which facilitates the adjustment of the overlapping part of screening holes 1 and 2, so as to adjust the screening diameter and ensure that the screening of plastic particles can be completed efficiently under various conditions. Precise adjustment of the screening hole diameter can also strictly control the particle size range of plastic particles, making the particle size of the final product more uniform.
