Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of screening, in particular to a particle screening device for processing plastic products. Background Art
[0002] Plastic particles, also known as plastic granules, refer to granular plastics. These plastic particles are generally divided into more than 200 types, and can even reach thousands of types if subdivided. Common plastic particles mainly include general-purpose plastics, engineering plastics and special plastics. In order to ensure the consistency of particle size during the processing process, screening devices are usually used. The screening device can screen out particles that do not meet the size requirements, thereby improving the quality and stability of the product.
[0003] Traditional particle screening devices usually consist of a feed port, a screen frame, a screen box and other components. First, the particle mixture to be separated is input into the screen frame from the feed port. Since the aperture size of the screen is fixed, particles larger than the aperture of the screen will be blocked above the screen, while particles smaller than the aperture of the screen will pass through the screen and fall into the screen box below. In this way, the particles in the mixture can be separated according to size through the different aperture sizes of the screen.
[0004] However, traditional particle screening devices cannot prevent plastic particles from clogging the screening plates. When plastic particles clog the screening plates, the screening process will be hindered, resulting in a decrease in the screening speed, thereby reducing the overall production efficiency. The clogged screening plates will also cause the particles to be unable to be screened according to the predetermined particle size distribution, thereby affecting the quality and performance of the product.

[0023] 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.
[0024] Reference Figure 1 - Figure 3 , the utility model provides an embodiment: a particle screening device for processing plastic products, comprising a hollow box 1, a feeding pipe 2 is fixedly connected to the top of the inner wall of the hollow box 1, a protective sleeve 3 is fixedly connected to the side wall of the hollow box 1, a motor 4 is fixedly connected to the inside of the protective sleeve 3, an eccentric column 5 is fixedly connected to the output end of the motor 4, a fixed column 6 is fixedly connected to the side wall of the eccentric column 5, a rotating plate 7 is rotatably connected to the outer wall of the fixed column 6, a support plate 10 is fixedly connected to the inner wall of the hollow box 1, a sliding column 9 is slidably connected to the inside of the support plate 10, one end of the sliding column 9 is fixedly connected to a hollow block 8, the rotating plate 7 is rotatably connected to the inside of the hollow block 8, and the other end of the sliding column 9 is fixedly connected to a fixed disk 11, a screening plate 12 is arranged inside the hollow box 1, and the lower surface of the screening plate 12 is in contact with one end of the fixed disk 11, an inclined plate 13 is fixedly connected to the inner wall of the hollow box 1, and a supporting assembly is arranged on the side wall of the hollow box 1;
[0025] Specifically, the power of the entire system comes from the output end of the motor 4. When the motor 4 is started, its output end will drive the eccentric column 5 to start rotating. The design of the eccentric column 5 is such that a centrifugal force will be generated when it rotates. This centrifugal force will further act on the fixed column 6, driving the fixed column 6 to rotate together. As the fixed column 6 rotates, the rotating plate 7 starts to rotate inside the hollow block 8 and gradually rises. This rising action is achieved through a series of precise mechanical connections to ensure smooth and accurate rotation. The rise of the rotating plate 7 will drive the sliding column 9 to slide inside the supporting plate 10. The rise of the sliding column 9 further drives the fixed plate 11 to rise. The rise of the fixed plate 11 is the key to the rotation of the screening plate 12. When the fixed plate 11 rises When the screen plate 12 is moved, it will cause the screen plate 12 to rotate and tilt. The design of this action cleverly utilizes the principle of lever and mechanical transmission to achieve rapid rotation of the screen plate 12. However, rotation is not the purpose. The real purpose is to make the screen plate 12 vibrate. Therefore, driven by the rotating plate 7, the sliding column 9 will drop again, driving the screen plate 12 to drop and rotate. The various components work together to complete the vibration of the screen plate 12. Finally, the plastic particles that pass through the screen plate 12 will be discharged through the discharge pipe 25. The design of the discharge pipe 25 takes into account the principles of fluid mechanics, ensuring that the plastic particles can flow out smoothly and avoiding blockage and accumulation problems. The plastic particles can be transported into the hollow box 1 through the feed pipe 2.
[0026] Reference Figure 1 and Figure 4 The support assembly includes a protection block 14, the protection block 14 is fixedly connected to the side wall of the hollow box 1, a cylinder 15 is fixedly connected inside the protection block 14, a fixed plate 19 is fixedly connected to the output end of the cylinder 15, a support block 16 is fixedly connected to the side wall of the protection block 14, a rotating rod 17 is rotatably connected to the side wall of the support block 16, a rotating rod 18 is rotatably connected to the inside of the rotating rod 17, the screening plate 12 is slidably connected to the inside of the hollow box 1, a clamping block 20 is fixedly connected to the side wall of the rotating rod 2 18, the clamping block 20 is rotatably connected to the inside of the fixed plate 19, and a connecting block 21 is slidably connected to the side wall of the clamping block 20;
[0027] Specifically, the cylinder 15 is started, and the piston rod of the cylinder 15 extends to push the fixed plate 19 forward. The movement of the fixed plate 19 will drive the rotating rod 17 connected thereto to rotate. The rotation of the rotating rod 17 will further drive the rotating rod 2 18 to rotate. The rotation of the rotating rod 2 18 will drive the clamping block 20 to rotate inside the fixed plate 19. When the clamping block 20 rotates to a position where it is no longer connected to the fixed connecting block 21.
[0028] Reference Figure 1 and Figure 4The upper surface of the connecting block 21 is fixedly connected to a connecting plate 22, the upper surface of the connecting plate 22 is fixedly connected to a baffle 23, the inside of the baffle 23 is rotatably connected to a hollow plate 24, the screening plate 12 is fixedly connected to the side wall of the hollow plate 24, and the bottom of the inner wall of the hollow box 1 is fixedly connected to a discharge pipe 25;
[0029] Specifically, pull the baffle 23 to move along a preset track or slide rail. The movement of the baffle 23 will drive the hollow plate 24 connected thereto to move together, and the hollow plate 24 and the screening plate 12 are connected together by bolts or other fasteners. Therefore, the movement of the hollow plate 24 will drive the screening plate 12 to slide inside the hollow box 1. Through such an operation, we can easily remove the screening plate 12. The removed screening plate 12 can be replaced, or the screened plastic particles can be further processed. It is worth mentioning that during the operation of the screening plate 12, it is sometimes necessary to vibrate it to improve the screening efficiency. During the vibration, the screening plate 12 will drive the hollow plate 24 connected thereto to rotate inside the baffle 23. This rotation is not only conducive to the uniform distribution of the material, but also prevents the material from accumulating on the screening plate 12, thereby improving the screening effect.
[0030] Working principle: when the staff needs to prevent the plastic particles from clogging the screening plate 12, first the eccentric column 5 is driven to rotate through the output end of the motor 4, the rotation of the eccentric column 5 will drive the fixed column 6 to rotate, the rotation of the fixed column 6 will drive the rotating plate 7 to rotate inside the hollow block 8 and rise, the rise of the rotating plate 7 will drive the sliding column 9 to slide inside the support plate 10, the rise of the sliding column 9 will drive the fixed plate 11 to rise, the rise of the fixed plate 11 will cause the screening plate 12 to rotate and tilt, and then driven by the rotating plate 7 will cause the sliding column 9 to descend and drive the screening plate 12 to descend and rotate, so that the screening plate 12 will vibrate, and then the clogging of the plastic particles is prevented, and the plastic particles passing through the screening plate 12 will be discharged through the discharge pipe 25. When the screening plate 12 needs to be disassembled, first, the fixed plate 19 is pushed to move by the cylinder 15. The movement of the fixed plate 19 will drive the rotating rod 17 to rotate, and the rotation of the rotating rod 17 will drive the rotating rod 2 18 to rotate. The rotation of the rotating rod 2 18 will drive the clamping block 20 to rotate inside the fixed plate 19. After the rotation of the clamping block 20, the position of the connecting block 21 is no longer fixed. Then the baffle 23 can be pulled, and the movement of the baffle 23 will drive the hollow plate 24 to move. The movement of the hollow plate 24 will drive the screening plate 12 to slide inside the hollow box 1. At this time, it can be disassembled, and the screening plate 12 can be replaced or larger plastic particles can be screened out. At the same time, when the screening plate 12 is vibrated, the screening plate 12 will drive the hollow plate 24 to rotate inside the baffle 23.
[0031] 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.
