Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a thermoplastic elastomer vibrating screening device. Background Technology

[0002] Thermoplastic elastomers, possessing both the elasticity of rubber and the processability of plastics, are widely used in the automotive, electronics, and medical fields. In their production and processing, vibrating screening is a key step in controlling material particle size and ensuring product quality. Existing vibrating screening devices mostly use motors to drive eccentric wheels to generate centrifugal vibration, which in turn drives the screen frame to separate materials. Although such devices can meet basic screening requirements, when processing thermoplastic elastomers, the screening effect is often limited due to the material's strong viscosity and tendency to agglomerate.

[0003] Currently, vibrating screening devices commonly suffer from screen clogging problems. On the one hand, under traditional centrifugal vibration, materials tend to accumulate locally on the screen surface, and sticky particles tend to adhere to the edges of the screen holes and gradually accumulate, leading to screen clogging. On the other hand, existing devices lack targeted anti-clogging structural designs, requiring shutdown for cleaning after clogging, which not only reduces production efficiency but may also affect the service life of the equipment due to frequent start-ups and shutdowns. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a thermoplastic elastomer vibrating screening device to solve the problems mentioned in the background. This invention features a novel structure, employing a screening structure that combines a reciprocating mechanism with a spring. The reciprocating mechanism drives the screen frame to continuously reciprocate, enhancing the dispersion of materials on the screen surface and reducing the accumulation of sticky materials. The elastic restoring effect of the spring further amplifies the vibration amplitude of the screen frame, increasing the material throughput. The gap between the scraper and the screen frame allows for real-time scraping of materials adhering to the screen bottom, reducing the risk of clogging. This improves upon the problems of low production efficiency and frequent shutdowns for cleaning caused by clogging in traditional devices, ensuring continuous and stable screening.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a thermoplastic elastomer vibrating screening device, comprising a processing box, two limiting slide rods fixedly connected to both sides of the inner wall of the processing box, a screen frame slidably fitted on the plurality of limiting slide rods, a mounting frame fixedly connected to one side of the processing box, a support frame fixedly connected to the upper side of the mounting frame, an annular support frame fixedly connected to the side of the support frame near the processing box, a winding reel rotatably fitted to the side of the annular support frame away from the processing box, a traction belt fixedly wound around the outer side of the winding reel, a traction mechanism provided on one side of the mounting frame, two springs provided on one side of the inner wall of the processing box, and a plurality of scrapers fixedly connected to the inner wall of the processing box.

[0006] Furthermore, the two springs are respectively sleeved on two limiting slide rods on one side of the inner wall of the processing box, and the two ends of the springs abut against one side of the inner wall of the processing box and one side of the screen frame, respectively. The upper end of the scraper is in clearance fit with the lower side of the screen frame.

[0007] Furthermore, the traction mechanism includes a drive motor mounted on one side of the mounting frame. The output end of the drive motor is fixedly connected to a square rod through one side of the mounting frame. An L-shaped mounting bracket is fixedly connected to one side of the mounting frame. A sleeve is slidably fitted to one end of the L-shaped mounting bracket. A compression spring is fitted on the sleeve. A drive plate is fixedly connected to one end of the sleeve through the winding reel. Two matching rods are symmetrically fixedly connected to one side of the winding reel. Trapezoidal extrusion blocks are arranged oppositely on one side of both ends of the support frame.

[0008] Furthermore, the sleeve is slidably fitted onto the square rod, and the two ends of the compression spring abut against the boss of the sleeve and one side of the L-shaped mounting bracket, respectively. The movable end of the drive plate is respectively fitted against one side of the mating rod and the inclined surface of the trapezoidal extrusion block.

[0009] Furthermore, a mounting bracket is installed on the upper side of the processing box, and a conveying assembly is provided inside the mounting bracket. A feed shell that cooperates with the conveying assembly is fixedly connected to the upper side of the mounting bracket.

[0010] Furthermore, the upper side of the processing box is provided with a feeding trough that cooperates with the feeding shell, and the feeding trough is located at the center above the screen frame.

[0011] Furthermore, a collection box is slidably fitted on one side of the processing box, and the collection box is located directly below the screen frame.

[0012] The beneficial effects of this utility model are: 1. This utility model features a screening structure with a reciprocating mechanism and a spring. The reciprocating mechanism drives the screen frame to move back and forth continuously, enhancing the dispersion of materials on the screen surface and reducing the accumulation of sticky materials. The elastic restoring effect of the spring further amplifies the vibration amplitude of the screen frame, improving the material throughput. The gap between the scraper and the screen frame allows for real-time scraping of materials adhering to the screen, reducing the risk of clogging. This improves upon the problems of low production efficiency and frequent shutdowns for cleaning caused by clogging in traditional devices, ensuring continuous and stable screening.

[0013] 2. By setting up a conveying component and a centrally located feeding chute, this utility model can improve the problem of uneven feeding in traditional devices. The conveying component can convey materials at a uniform speed. Combined with the feeding chute located in the center above the screen frame, the materials fall accurately into the middle of the screen frame, avoiding material accumulation that causes excessive local screening load, ensuring maximum utilization of the screen surface, and further improving the overall screening efficiency.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Please refer to Figures 1 to 5This utility model provides a technical solution: a thermoplastic elastomer vibrating screening device, including a processing box 1. Two limiting slide rods 2 are fixedly connected to both sides of the inner wall of the processing box 1. A screen frame 3 is slidably fitted on multiple limiting slide rods 2. A mounting frame 4 is fixedly connected to one side of the processing box 1. A support frame 5 is fixedly connected to the upper side of the mounting frame 4. An annular support frame 6 is fixedly connected to the side of the support frame 5 near the processing box 1. A winding reel 7 is rotatably fitted to the side of the annular support frame 6 away from the processing box 1. A traction belt 8 is wound and fixedly fixed to the outer side of the winding reel 7. A traction mechanism 9 is provided on one side of the mounting frame 4. Two springs 10 are provided on one side of the inner wall of the processing box 1. Multiple scrapers 11 are fixedly connected to the inner wall of the processing box 1. The two springs 10 are respectively sleeved on the two limiting slide rods 2 on one side of the inner wall of the processing box 1. The two ends of the springs 10 abut against one side of the inner wall of the processing box 1 and one side of the screen frame 3, respectively. The upper end of the scraper 11 is clearance-fitted with the lower side of the screen frame 3. After the material enters the processing box 1, it falls onto the screen frame 3. The screen frame 3 slides along the limiting slide bar 2. The traction mechanism 9 on the mounting frame 4 takes up and releases the traction belt 8 through the winding reel 7. In conjunction with the spring 10 in the processing box 1, it drives the screen frame 3 to reciprocate to achieve screening. The scraper 11 is fitted with the lower side of the screen frame 3 with a gap, which can scrape off the attached material and reduce screen hole blockage. The spring 10 enhances the vibration amplitude of the screen frame 3 through elastic reset, thereby improving screening efficiency.

[0018] In this embodiment, the traction mechanism 9 includes a drive motor 91 mounted on one side of the mounting frame 4. The output end of the drive motor 91 is fixedly connected to a square rod 92 through one side of the mounting frame 4. An L-shaped mounting frame 93 is fixedly connected to one side of the mounting frame 4. A sleeve 94 is slidably fitted to one end of the L-shaped mounting frame 93. A compression spring 95 is fitted on the sleeve 94. A drive plate 96 is fixedly connected to one end of the sleeve 94 through the winding reel 7. Two mating rods 97 are symmetrically fixedly connected to one side of the winding reel 7. Trapezoidal extrusion blocks 98 are arranged oppositely on one side of both ends of the support frame 5. The sleeve 94 is slidably fitted on the square rod 92. The two ends of the compression spring 95 abut against the boss of the sleeve 94 and one side of the L-shaped mounting frame 93, respectively. The movable end of the drive plate 96 engages with one side of the mating rod 97 and the inclined surface of the trapezoidal extrusion block 98, respectively. The drive motor 91 drives the square rod 92 to rotate, causing the sleeve 94 to rotate with the square rod 92. The compression spring 95 pushes the drive plate 96 on the sleeve 94 to contact the mating rod 97 of the winding reel 7, driving the winding reel 7 to rotate and wind up the traction belt 8. When the drive plate 96 contacts the trapezoidal extrusion block 98 on the support frame 5, it is extruded and disengaged from the mating rod 97, the winding reel 7 stops rotating, and the spring 10 pulls the screen frame 3 to reset. This cycle is repeated to achieve continuous reciprocating motion of the screen frame 3, ensuring stable structural linkage and continuous screening.

[0019] In this embodiment, a mounting bracket 12 is installed on the upper side of the processing box 1. A conveying assembly 13 is disposed inside the mounting bracket 12, and a feed shell 14 that cooperates with the conveying assembly 13 is fixedly connected to the upper side of the mounting bracket 12. A feed chute 15 that cooperates with the feed shell 14 is opened on the upper side of the processing box 1, and the feed chute 15 is located at the center above the screen frame 3. A collection box 16 is slidably fitted on one side of the processing box 1, and the collection box 16 is located directly below the screen frame 3. The material enters the conveying assembly 13 of the mounting bracket 12 through the feed shell 14, and is then conveyed by the conveying assembly 13 to the center above the screen frame 3 through the feed chute 15 of the processing box 1, ensuring uniform feeding. The screened material falls into the collection box 16 below, and the collection box 16 can be slidably removed for convenient material collection. This structure ensures smooth connection between the feeding, screening, and collection processes, reduces material accumulation, and improves overall processing efficiency.

[0020] When using the device, the material enters from the feed shell 14, is conveyed by the conveying assembly 13 and evenly fed to the screen frame 3 through the feed trough 15. The drive motor 91 drives the square rod 92 to rotate, so that the drive plate 96 on the sleeve 94 engages with the cooperating rod 97 of the winding reel 7, driving the winding reel 7 to wind up the traction belt 8, pulling the screen frame 3 to move along the limiting slide bar 2 and compressing the spring 10. When the drive plate 96 contacts the trapezoidal extrusion block 98, it disengages from the cooperating rod 97, and the spring 10 resets, pushing the screen frame 3 to slide in the opposite direction, forming a reciprocating vibrating screening. The scraper 11 scrapes off the attached material on the lower side of the screen frame 3 to prevent clogging. After screening, the material falls into the collection box 16, realizing efficient and continuous screening.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
