Description

Technical Field

[0001] This utility model relates to the technical field of vibrating sieving devices, specifically a vibrating sieving device for plastic particles. Background Technology

[0002] In the production and recycling of plastic products, the screening of plastic particles is a crucial step in controlling the consistency of raw material particle size, directly affecting the stability of subsequent processing and product quality. Current technologies commonly employ equipment such as drum screens, vibrating screens, or inclined screens for plastic particle grading. These devices typically have a multi-layer structure, with each layer of screen corresponding to a specific particle size range. Plastic particles pass through the screens layer by layer by gravity or vibration.

[0003] However, these screening devices generally suffer from complex structures, large footprints, difficulty in disassembly and assembly, and inconvenient replacement. Furthermore, the screens are prone to clogging and are difficult to clean. In practical applications, to adapt to different particle size screening requirements, frequent replacement of the entire screen structure is necessary, resulting in time-consuming, labor-intensive operations and high maintenance costs. In addition, some screening equipment uses a planar or inclined layered screen arrangement, leading to short particle screening paths and limited throughput time, making efficient classification control difficult, especially when dealing with mixed particles of similar sizes, resulting in low screening accuracy.

[0004] Existing technologies also lack a compact, modular, adjustable vibrating screening device that can adapt to different screening particle size requirements and is easy to clean and maintain. Therefore, there is an urgent need for an improved plastic particle screening solution that can achieve high grading efficiency, easy screen replacement, and stable and reliable structure to meet the needs of efficient and high-precision screening in industrial applications. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows: a plastic particle vibrating sieving device, including a vibrating bowl, a filter box and a vibrating seat, wherein the vibrating bowl is installed on the vibrating seat and has a conveying rail arranged in a spiral direction and a discharge hopper connected thereto. The plastic particles are conveyed along the conveying rail under the action of excitation force and are screened in stages through multiple filter boxes to achieve efficient screening.

[0007] In a preferred embodiment, the vibrating bowl is further configured such that: the vibrating bowl is mounted on a vibrating base, and its interior is provided with a conveying rail arranged along a spiral path. A discharge hopper is located at the end of the conveying rail. Under the action of vibration, plastic particles move along the rail towards the discharge hopper, thereby forming an effective spiral conveying path. Specifically, this structure provides the plastic particles with a longer screening path, which is beneficial for achieving thorough screening and improving the accuracy of particle size screening.

[0008] In a preferred embodiment, the filter box is further configured as follows: the filter box consists of several detachable modules arranged and installed on its surface along the conveyor rail; a filter screen is provided on the surface of the filter box, and the pore size of the filter screens of multiple filter boxes increases sequentially along the conveying direction of the plastic particles. Specifically, this structure achieves graded screening, allowing smaller particles to pass through the small-pore filter screen preferentially for separation, while larger particles continue to move forward. By using an appropriate filter screen for graded discharge, screening efficiency and grading accuracy are improved.

[0009] In a preferred embodiment, the filter box is further configured as follows: it has an arc-shaped structure, is embedded and fitted onto the surface of the conveyor rail, and has snap-fit ​​structures on both sides to adapt to the conveyor rail, enabling the filter box to be detached and installed. Specifically, the snap-fit ​​connection method enables quick assembly and disassembly of the filter box, which is beneficial for adjusting the filter screen specifications according to different screening requirements, and also facilitates cleaning and maintenance, improving the overall adaptability and operational efficiency of the equipment.

[0010] In a preferred embodiment, the filter screen on the surface of the filter box is flush with the top surface of the conveyor rail, and the filter screen adopts a honeycomb structure. Specifically, this arrangement ensures the continuity of particle screening during movement and avoids accumulation; the honeycomb structure can effectively enhance the strength of the screen, improve wear resistance and permeability, and extend service life.

[0011] In a preferred embodiment, the vibrating bowl is further configured such that the vibrating force generated by the vibrator achieves circumferential vibration, thereby driving the plastic particles to be conveyed along a spiral track. The conveying track is spiral-shaped and configured with an inner diameter that gradually increases from bottom to top. Specifically, this structure can form a stable spiral flow of particles, improve material dispersion, avoid material aggregation, and help improve screening effect and flowability.

[0012] In a preferred embodiment, the vibration seat is further configured as follows: the vibration seat includes a base, a floating disk, a vibrator, and a support bar. The floating disk is disposed above the base and connected to the base via the support bar. The bottom surface of the floating disk is provided with connecting ears, which are connected to the vibrator. Specifically, this vibration seat structure can effectively transmit the excitation force to the vibrating bowl, while also possessing good buffering and shock absorption capabilities, thereby improving the overall structural stability and operational reliability.

[0013] In summary, this utility model, through the rational design of the vibrating bowl structure, the segmented arrangement of filter boxes, and the formation of a spiral screening path, has achieved a significant improvement in particle screening accuracy and efficiency. At the same time, it enhances the ease of maintenance and modular adaptability of the structure, making it suitable for efficient screening and grading applications of plastic particles of various sizes.

[0014] The beneficial effects achieved by this utility model are as follows: 1. In this utility model, the filter box can be detachably installed on the surface of the conveyor rail, which makes it easy to replace the filter screen with different aperture size for screening according to actual needs, thereby improving the adaptability and maintenance convenience of the device.

[0015] 2. In this utility model, the filter boxes are arranged sequentially along the spiral conveying rail, and the filter screen aperture increases step by step, which can realize the grading and screening of plastic particles and improve the screening efficiency and accuracy.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0019] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0020] The following describes, with reference to the accompanying drawings, some embodiments of a plastic particle vibrating sieve device provided by this utility model.

[0021] Combination Figures 1-4As shown, this utility model provides a vibrating sieving device for plastic particles, comprising: a vibrating bowl 100, filter boxes 200, and a vibrating base 300, wherein the vibrating bowl 100 is mounted on the vibrating base 300. The vibrating bowl 100 has a conveying rail 110 arranged in a spiral direction inside, and one end of the conveying rail 110 is connected to a discharge hopper 120. Plastic particles move along the conveying rail 110 towards the discharge hopper 120 through vibration. Several filter boxes 200 are provided, with a segmented and detachable structure, and are respectively installed at different positions on the conveying rail 110 for step-by-step sieving of plastic particles.

[0022] Each filter box 200 has a filter screen 201 on its surface for screening plastic particles according to their size. Multiple filter boxes 200 are arranged sequentially along the conveying direction of the conveying rail 110, and the aperture of the filter screen 201 in each filter box 200 increases sequentially. Through this structure, particles with a diameter smaller than the aperture of the filter screen 201 can pass through the filter screen 201 and enter the collection area below, while larger particles continue to move forward and are eventually discharged through the discharge hopper 120.

[0023] Furthermore, the filter box 200 has an arc-shaped structure, which fits snugly against the shape of the conveyor rail 110, forming an integrated screening track with the surface of the vibrating bowl 100. The filter box 200 has snap-fit ​​structures on both sides that match the surface of the conveyor rail 110, enabling quick installation and removal of the filter box 200. This facilitates the replacement of different screen sizes to meet different particle size screening requirements, and also facilitates cleaning and maintenance, reducing downtime during production.

[0024] like Figure 3 and Figure 4 As shown, the filter screen 201 on the surface of the filter box 200 is positioned on the same plane as the top surface of the conveyor rail 110, ensuring that plastic particles pass smoothly through during the screening process and avoiding accumulation. The filter screen 201 adopts a honeycomb structure design with uniform pore distribution, which helps to improve screening permeability and accuracy, and also enhances the mechanical strength of the filter screen 201.

[0025] like Figure 1 and Figure 2 As shown, the vibrating bowl 100 operates through the excitation force provided by the vibrator 330, and the vibration mode is circumferential vibration, which drives the plastic particles to move along the spiral path of the conveyor rail 110. The conveyor rail 110 is spirally arranged from the bottom of the vibrating bowl 100 upwards, and the inner diameter of the spiral path gradually increases, which helps to divert particles, avoid accumulation, and improve screening efficiency and throughput.

[0026] The vibrating base 300 includes a base 310, a floating disk 320, a vibrator 330, and a support bar 311. The floating disk 320 is mounted on the base 310, and the support bar 311 is set on the base 310 and supports the floating disk 320. The vibrator 330 is mounted on the base 310, and its output end is fixedly connected to a connecting ear 321 provided on the bottom surface of the floating disk 320. When the vibrator 330 is working, it drives the floating disk 320 to vibrate through the connecting ear 321, thereby driving the entire vibrating bowl 100 to vibrate, realizing the automatic screening and conveying of plastic particles.

[0027] The embodiments of this utility model have the advantages of compact structure, replaceable modules, high screening accuracy, and convenient installation and maintenance. They are suitable for screening and grading various plastic particles, and are especially suitable for industrial applications that require efficient and continuous screening of plastic particles of different sizes.

[0028] Working principle and usage process of this utility model: In use, the plastic particle vibrating sieving device of this utility model consists of several filter boxes 200 installed on the surface of the conveying rail 110 on the vibrating bowl 100 via a snap-fit ​​structure. The surface of the filter box 200 is provided with filter screens 201, and the aperture of each filter screen 201 increases sequentially along the conveying direction of the plastic particles. The filter box 200 has an arc-shaped structure and is fitted to the conveying rail 110. After the device is started, the vibrator 330 in the vibrating seat 300 generates an excitation force, which drives the floating plate 320 to vibrate. The floating plate 320 is connected to the base 310 via a support bar 311 and is fixedly connected to the vibrating bowl 100 via a connecting ear 321, so that the vibrating bowl 100 vibrates in a circumferential direction. This causes the plastic particles to move from bottom to top along a spiral path on the conveying rail 110 and pass through the filter boxes 200 for sieving step by step. Particles with a particle size smaller than the aperture of the current filter screen 201 will fall into the filter box 200, while particles with a different particle size continue to be conveyed forward and are finally discharged from the discharge hopper 120.
