Description

Technical Field

[0001] This utility model relates to the field of plastic processing, specifically a screening rack for plastic processing. Background Technology

[0002] A screening rack is a device used for screening, classifying, and sorting materials, typically consisting of a metal frame and a screen. It separates materials of different sizes based on the mesh size of the screen and is widely used in industries such as mining, agriculture, chemicals, and food processing. Screening racks are characterized by their simple structure, convenient operation, and high screening efficiency, effectively improving the speed and accuracy of material handling. They are an indispensable piece of equipment in industrial production and material processing.

[0003] Plastics processing refers to the process of transforming plastic raw materials into plastic products with specific shapes, sizes, and properties through a series of physical or chemical methods. This process includes stages such as plastic formulation, mixing, plasticizing, molding, cooling, trimming, and post-processing, involving various molding technologies such as injection molding, extrusion, blow molding, and calendering. The development of plastics processing technology has continuously promoted the diversification and high performance of plastic products, meeting the needs of various sectors of society for lightweight, corrosion-resistant, and easy-to-process materials.

[0004] However, existing screening racks for plastic processing are insufficient in terms of screening efficiency, usually using only a single vibration process for screening. In addition, the equipment lacks a dust removal device for the required plastic particles after screening. This defect can easily lead to quality problems in subsequent processing, affecting the purity and processing effect of the final product. To address the above problems, a screening rack for plastic processing is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a screening rack for plastic processing, which solves the problems of low screening efficiency and lack of dust removal device for the plastic particles after screening in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a screening rack for plastic processing, comprising a support base, a base fixedly connected to one end of the top of the support base, a first crossbar rotatably connected through and through one end of the base, a second positioning ring fixedly connected to the other side of the outer ring of the first crossbar, a first rotating plate fixedly connected to one end of the first crossbar, a first connecting rod rotatably connected to one end of the first rotating plate, a second crossbar rotatably connected through and through one end of the first connecting rod, a second rotating rod rotatably connected through and through one side of the base, telescopic rods rotatably connected to both ends of the outer ring of the second rotating rod, a third rotating rod rotatably connected through and through one side of the telescopic rod, a screen rotatably connected to the outer ring of the third rotating rod, a second rotating plate fixedly connected to the other end of the first crossbar, a large collection box slidably connected to the other end of the top of the support base, a first suction disc threadedly connected to one end of the outer wall of the large collection box, the first suction disc being fixedly connected to a pipe, and a dust collection assembly provided on the top of the support base.

A second rotating plate 21 is fixedly connected to the other end of the first horizontal rod 4. One end of the second rotating plate 21 is rotatably connected to the outer ring of the second connecting rod 25. A connecting plate 22 is fixedly connected to one side of one end of the second rotating plate 21. A connecting rod 23 is fixedly connected to one end of the connecting plate 22. A pad 26 is fixedly connected to one side of the support base 1. A servo motor 24 is fixedly connected to the top of the pad 26 to provide power for the entire device to operate. The output end of the servo motor 24 is fixedly connected to the connecting rod 23. A dust collection and removal assembly is provided on the top of the support base 1.

[0033] Reference Figure 2 and Figure 3 The dust collection component includes a small collection box 11, the bottom of which is slidably connected to the other end of the top of the support base 1, allowing for easy disassembly and cleaning. A large collection box 12 is slidably connected to one end of the outer wall of the small collection box 11, and a second suction plate 14 is threadedly connected to one end of the outer wall of the small collection box 11, ensuring a secure connection and easy disassembly and replacement. A pipe 18 is fixedly connected to one side of the second suction plate 14, providing a clear flow path for the gas, which helps guide and concentrate the gas, improving suction efficiency. A first suction plate 13 is threadedly connected to one end of the outer wall of the large collection box 12. When the suction fan 16 is started, impurities can be sucked out through the first suction plate 13. A storage box 15 is fixedly connected to the bottom of the pipe 18 for storing the sucked-out impurities. After all the impurities are sucked out, the suction fan 16 is turned off, and the storage box 15 is opened to remove all the impurities.

[0034] Reference Figure 3A second filter 19 is slidably connected through one side of the inner wall of the small collection box 11. The second filter 19 can prevent small plastic particles from being sucked into the pipe 18. A first filter 17 is slidably connected through one end of the inner wall of the large collection box 12.

A third filter 27 is slidably connected through one side of the inner wall of the storage box 15 to prevent impurities from entering the suction fan 16.

[0035] Working principle: During the screening process, the particles to be screened are first poured into the screen 9. Then, the servo motor 24 is started, which drives the connecting plate 22 to rotate via the connecting rod 23, thereby triggering the movement of the second connecting rod 25. This series of actions causes the rotating second plate 21 to rotate, further driving the first crossbar 4 and the first rotating plate 3 to rotate, ultimately causing the first connecting rod 6 to move. Since the second crossbar 10 is fixedly connected to the screen 9, the screen 9 reciprocates along with the first connecting rod 6 and the second connecting rod 25, achieving a vibration effect. In addition, the telescopic rod 7, which acts on the screen 9 via the third rotating rod 30, can adjust the inclination of the screen 9, effectively accelerating the screening rate. After selection, the angle of the screen 9 is changed by adjusting the telescopic rod 7, and the large plastic particles are smoothly poured into the large collection box 12 and the lid is closed. Thanks to the inclined design of the top of the base 2, the small plastic particles naturally slide into the small collection box 11 and the lid is closed as well. To further ensure the purity of the particles, the suction fan 16 is turned on. Through the pipe 18, the first suction plate 13 and the second suction plate 14, the impurities attached to the large and small plastic particles are effectively sucked out and collected into the storage box 15. To prevent particles from clogging, the suction fan 16 is turned off and then turned on again after a period of time to ensure the smooth progress of the entire screening and dust removal process, providing a reliable guarantee for subsequent processing.
