Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, specifically to a plastic particle screening equipment with adaptive aperture adjustment function. Background Technology

[0002] In the production of many plastic products, the size of plastic particles directly affects the quality of the final product. Plastic particles of different diameters may cause inconsistent material flowability, thus affecting product quality. Furthermore, if the plastic particles contain substandard particles, it will lead to wear and tear on the production equipment. Therefore, it is necessary to screen the plastic particles before processing.

[0003] Plastic particles are usually screened using sieves. The required size of plastic particles varies at different stages of the production process. Most existing sieves have fixed aperture sizes that cannot be adjusted according to production needs. The sieves can only be removed and replaced, which increases working time, reduces work efficiency, and diminishes practicality. Utility Model Content

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0025] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0026] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0027] Combined with appendix Figure 1 As shown, a plastic particle screening device with adaptive aperture adjustment function includes a screening box 1. The screening box 1 is equipped with a vibration motor, and vibration springs 14 are respectively located at the four corners of the screening box 1. The vibration motor drives the screening box 1 to vibrate, and the screening operation is realized with the cooperation of the vibration springs 14. A sieve plate assembly is connected inside the screening box 1, and a slot matching the sieve plate assembly is provided inside the screening box 1. One end of the slot passes through the screening box 1.

[0028] Combined with appendix Figures 4 to 6 As shown, the sieve plate assembly is composed of a housing 1 (2), a housing 2 (3), and an adjusting plate 4. The adjusting plate 4 is slidably disposed between the housing 1 (2) and the housing 2 (3). A sliding plate 10 is symmetrically provided on the adjusting plate 4 opposite to the push block 9. A groove 11 matching the sliding plate 10 is provided on the contact surface of the housing 2 (3) with the adjusting plate 4. The sliding plate 10 slides within the groove 11. This design makes the sliding of the adjusting plate 4 within the housing more stable. The internal length of the housing 1 (2) and the housing 2 (3) is greater than the length of the adjusting plate 4. The upper and lower ends of the adjusting plate 4 are respectively attached to the inner walls of the housing 1 (2) and the housing 2 (3). The adjusting plate 4 is tightly attached to the upper surface of the housing 1 (2) and the housing 2 (3) to prevent plastic particles from getting stuck in the gaps during screening, which would affect the screening efficiency. Screening holes 5 are provided on the surfaces of the housing 1 (2) and the housing 2 (3). The adjusting plate 4 is provided with adjusting holes 6 that are adapted to the screening holes 5. The adjusting holes 6 and the screening holes 5 are hexagonal structures.

[0029] Combined with appendix Figure 2 , Figure 3 and Figure 6As shown, the housing 2 has a sliding hole 7 on one side, and the adjusting plate 4 is connected to a push block 9 via a connecting block 8 on one side. The connecting block 8 is slidably located within the sliding hole 7. The outer side of the housing 2 is provided with several positioning teeth 12 at equal intervals on one side of the sliding hole 7. The push block 9 is provided with a groove 13. The groove 13 is connected to a locking tooth 15 that meshes with the positioning tooth 12 via symmetrically arranged springs 14. Both the locking tooth 15 and the positioning tooth 12 are bidirectional tooth structures. A protective cover 16 is provided on the housing 2 above the sliding hole 7. The protective cover 16 is a semi-enclosed structure. The semi-enclosed structure design allows the push block 9 to slide easily while protecting the positioning tooth 12, preventing plastic particles from getting stuck between the tooth grooves of the positioning tooth 12 and causing adjustment failure.

[0030] Combined with appendix Figure 4 As shown, the housing 1 2 and housing 2 3 are fixedly connected by bolts. The bolt connection method facilitates the assembly of the screen plate assembly. Multiple connecting rods 17 are provided at equal intervals on one side of the housing 1 2. The housing 2 3 is provided with connecting pipes 18 that are adapted to the connecting rods 17. The connecting rods 17 are inserted into the connecting pipes 18 to connect the housing 1 2 and housing 2 3, and at the same time form a handle to facilitate the installation and disassembly of the screen plate assembly.

[0031] When the adjusting plate 4 is not adjusted, the adjusting hole 6 and the screening hole 5 on the adjusting plate 4 are in an alternating state. At this time, the screening hole 5 is closed by the adjusting plate 4. The push block 9 is moved towards the connecting rod 17 along the sliding hole 7. At this time, the locking tooth 15 continuously contracts and pops out under the action of the spring 14, so as to cooperate with the positioning tooth 12 to fix the position of the push block 9, so as to ensure the stability of the adjusting plate 4 and avoid the hole diameter from changing during use. The contact surfaces of the positioning tooth 12 and the locking tooth 15 are both inclined, which allows the locking tooth 15 to better bear the force and move in an extension and retraction motion.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
