Description

Technical Field

[0001] This utility model relates to the field of plastic gasket production technology, and in particular to a raw material screening device for plastic gasket production. Background Technology

[0002] In the production of plastic gaskets, raw material selection is a crucial step in ensuring product quality. Appropriate raw material particle size ensures that the plastic gaskets possess good molding properties and stable physical properties during subsequent processing.

[0003] Currently, most raw material screening methods rely on manual screening or the use of simple sieves. Manual screening is inefficient, labor-intensive, and its accuracy is greatly affected by human factors, making it difficult to guarantee the stability of screening quality. Simple sieve screening devices typically have a limited structure, mostly possessing only basic screening functions and lacking effective drive and guiding mechanisms. During the screening process, raw materials tend to accumulate on the sieve, leading to insufficient screening. Furthermore, adjusting the sieve or screening parameters is difficult when screening raw materials with different particle size requirements. Utility Model Content

[0012] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0013] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Identical components are indicated by the same reference numerals.

[0014] This embodiment provides a raw material screening device for plastic gasket production, which mainly consists of a receiving component 1, a bearing component 3, a screening component 4, and a driving component 5. Each component is fixedly mounted on a base plate 2. Through the coordinated cooperation between the components, the screening of raw materials for plastic gasket production is achieved.

[0015] In this embodiment, the receiving assembly 1 includes a receiving box 101, strip-shaped through holes 102, and a discharge pipe 103. The receiving box 101 is rectangular in shape and is fixedly mounted on the top of the base plate 2 by welding or bolting, etc., for receiving the screened raw materials. A strip-shaped through hole 102 is provided on each of the opposite side walls of the receiving box 101, providing space for the movement of the subsequent supporting assembly 3. The discharge pipe 103 is fixedly mounted below the receiving box 101, and its shape can be designed according to actual needs, for discharging the screened raw materials from the receiving box 101.

[0016] In this embodiment, the supporting component 3 includes a supporting horizontal plate 301, a guide shaft 302, a guide sleeve 303, a guide connecting rod 304, and a supporting groove 305. Pairs of supporting horizontal plates 301 are symmetrically arranged on the outer wall of the receiving box 101, for example, fixed to the outer sides of the two side walls of the receiving box 101 by welding. The guide shaft 302 is horizontally fixed between the two supporting horizontal plates 301, providing a track for the subsequent sliding of the guide sleeve 303. The guide sleeve 303 is fitted onto the guide shaft 302 and can perform reciprocating linear motion on the guide shaft 302. The guide connecting rod 304 is inserted into two strip-shaped through holes 102, and one end is fixedly connected to the guide sleeve 303, for example, by welding or bolting. Thus, when the guide sleeve 303 moves on the guide shaft 302, it drives the guide connecting rod 304 to reciprocate within the strip-shaped through holes 102. The supporting groove 305 is fixedly arranged at the other end of the guide connecting rod 304 and is used to support the screening component 4.

[0017] In this embodiment, the screening component 4 includes a screening box 401, screening holes 402, a fixing cross plate 403, a limiting threaded hole 404, and a limiting bolt 405. The screening box 401 is rectangular in shape and is placed on the bearing groove 305 to hold the raw materials for the production of plastic gaskets to be screened. Multiple screening holes 402 are evenly opened on the lower end face of the screening box 401. The aperture size of the screening holes 402 can be designed according to the actual screening requirements. Raw materials that meet the aperture requirements will fall into the receiving box 101 through the screening holes 402. Two fixing cross plates 403 are symmetrically arranged on the outer wall of the screening box 401, for example, by welding. The limiting threaded hole 404 is opened on the upper end face of the bearing groove 305. The limiting bolt 405 is inserted into the fixed horizontal plate 403 and the limiting bolt 405 is threadedly connected to the limiting threaded hole 404. The screening box 401 is fixed on the bearing groove 305 through this connection method to prevent the screening box 401 from shaking or shifting during the screening process.

[0018] In this embodiment, the drive assembly 5 includes a tray 501, an elastic damper 502, a drive connecting frame 503, and a vibration motor 504. Two trays 501 are symmetrically arranged on the outer wall of the receiving box 101, for example, by welding. The elastic damper 502 is fixedly disposed on top of the tray 501. The elastic damper 502 can be made of elastic materials such as rubber, serving as a buffer and shock absorber. The drive connecting frame 503 is fixedly disposed between the elastic damper 502 and the guide sleeve 303, for example, by welding or bolting, and is used to transmit the vibration generated by the vibration motor 504 to the guide sleeve 303. The vibration motor 504 is fixedly disposed on top of the drive connecting frame 503. When the vibration motor 504 starts, it generates vibration, which is transmitted to the guide sleeve 303 through the drive connecting frame 503 and the elastic damper 502, causing the guide sleeve 303 to reciprocate linearly on the guide shaft 302. This, in turn, drives the guide connecting rod 304, the bearing groove 305, and the screening assembly 4 to reciprocate, thereby achieving the screening of raw materials.

[0019] The working process is as follows: The raw materials for producing plastic gaskets to be screened are poured into the screening box 401. The vibration motor 504 is started. The vibration generated by the vibration motor 504 is transmitted to the guide sleeve 303 through the drive connecting frame 503 and the elastic damper 502. The guide sleeve 303 reciprocates linearly on the guide shaft 302, driving the guide connecting rod 304, the bearing groove 305, and the screening box 401 to reciprocate. During the vibration process, raw materials that meet the aperture requirements of the screening holes 402 fall into the receiving box 101 through the screening holes 402 and are then discharged through the discharge pipe 103, thus completing the screening of the raw materials.

[0020] The above are merely preferred embodiments of this utility model patent and are not intended to limit this utility model patent. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
