Description

Technical Field

[0001] This utility model relates to the technical field of PVC particle processing equipment, and in particular to a PVC particle screening device. Background Technology

[0002] PVC granules are granular materials made primarily of polyvinyl chloride through specific processes. It is a thermoplastic resin material with good plasticity, chemical resistance, and mechanical strength, and is widely used in construction, wire and cable, packaging, medical devices, and other fields.

[0003] In the PVC granule processing, the PVC granules need to be screened to select qualified PVC granules. During the PVC granule processing, dust and impurities are easily attached to the PVC granules. If dust and impurities are mixed into the final product, it will not only affect the purity of the PVC granules, but may also affect their physical properties and the quality of the final product.

[0004] Therefore, there is a need to provide a PVC particle screening device. Utility Model Content

[0005] In order to overcome the shortcomings of PVC granules, which are prone to dust and impurities adhering to them during the PVC granule processing, and which can affect the purity of PVC granules and their physical properties if they are mixed into the final product, this utility model provides a PVC granule screening device.

[0006] This utility model is achieved through the following technical means: a PVC particle screening device, including a bracket, a fixed frame, spring plates, a first screening frame, a dual-axis motor, a cam, a connecting rod, a rotating shaft, a second screening frame, and a first collection frame. Four spring plates are fixedly connected inside the bracket, and the first screening frame is fixedly connected between the four spring plates. A dual-axis motor is installed on the top left side of the first screening frame, and a cam is fixedly connected to the output shaft of the dual-axis motor. Identical spring plates are symmetrically fixed to both sides of the first screening frame, and a second screening frame is fixedly connected between the four corresponding spring plates. A rotating shaft is fixedly connected to the right side of the second screening frame, and a connecting rod is connected between the end of the rotating shaft and the adjacent cam. The first collection frame is slidably arranged at the bottom inside the bracket. The device also includes a support block, a protective shell, a battery, and an electrode plate. A support block is fixedly connected to the upper left side of the bracket, and a protective shell is fixedly connected to the top of the support block. A battery is placed inside the rear side of the protective shell, and an electrode plate is connected to the front side of the battery.

[0007] Furthermore, it also includes an electric push rod and a partition. An electric push rod is installed on the rear side of the bottom of the support block, and a partition is fixed to the telescopic rod of the electric push rod. The partition slides inside the support block.

[0008] Furthermore, it also includes a single-axis motor, a screw, a fixed rod, and a scraper. The single-axis motor is installed on the lower right rear side of the bracket. The output shaft of the single-axis motor is fixedly connected to the screw via a coupling. The fixed rod is fixedly connected inside the bracket. The scraper is slidably mounted on the fixed rod. The scraper is threadedly connected to the screw and is located above the first collection frame.

[0009] Furthermore, it also includes a funnel, with the funnel fixed to the protective shell.

[0010] Furthermore, it also includes a second collection frame, which is slidably mounted on the front side of the bracket and is located below the first filter frame.

[0011] Furthermore, it also includes a limiting mesh, which is fixed to the top of the bracket.

[0012] As can be seen from the above description of the structure of this utility model, the design starting point, concept, and advantages of this utility model are:

[0013] 1. By pouring an appropriate amount of PVC granules into the protective shell and simultaneously injecting current into the electrode plate, a large static electricity is generated on the electrode plate, which can absorb the dust and impurities on the PVC granules. This allows the dust and impurities to be adsorbed onto the electrode plate, thereby achieving the purpose of removing impurities and preventing dust from affecting the final product quality of the PVC granules.

[0014] 2. By activating the electric push rod, the telescopic rod of the electric push rod drives the partition to move forward, thereby blocking the discharge port of the protective shell and preventing excessive PVC particles from overflowing the first screening frame.

[0015] 3. By starting the single-axis motor, the output shaft of the single-axis motor drives the screw to rotate and moves the scraper forward, thereby leveling the PVC particles and preventing the PVC particles from overflowing the first collection frame. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0024] Example: A PVC particle screening device, see reference. Figures 1-6 As shown, the system includes a bracket 1, a fixing frame 2, spring plates 3, a first screening frame 4, a dual-axis motor 5, a cam 6, a connecting rod 7, a rotating shaft 8, a second screening frame 9, a first collection frame 10, a funnel 21, a second collection frame 22, and a limiting net 23. Spring plates 3 are symmetrically fixed to the upper left and right sides of the bracket 1. A first screening frame 4 is fixed between four spring plates 3. A dual-axis motor 5 is bolted to the top left side of the first screening frame 4. A cam 6 is fixed to the output shaft of the dual-axis motor 5. Identical spring plates 3 are symmetrically fixed to the left and right sides of the first screening frame 4. A second screening frame 9 is fixed between four corresponding spring plates 3. A rotating shaft 8 is fixed to the right side of the second screening frame 9. The end of the rotating shaft 8 is connected to the adjacent cam 6. The bracket 1 is connected to a connecting rod 7. A first collection frame 10 is slidably installed at the bottom of the bracket 1. A funnel 21 is fixed to the protective shell 12 to prevent PVC particles from splashing out during feeding. A second collection frame 22 is slidably installed on the front side of the bracket 1. The second collection frame 22 is located below the first screening frame 4 and is convenient for workers to collect. A limiting net 23 is fixed to the top of the bracket 1 to prevent PVC particles from flying out of the bracket 1 during screening. The bracket 1 also includes a support block 11, a protective shell 12, a battery 13, and an electrode plate 14. A support block 11 is fixed to the upper left part of the bracket 1. A protective shell 12 is fixed to the top of the support block 11. A battery 13 is placed inside the rear side of the protective shell 12. An electrode plate 14 is connected to the front side of the battery 13.

[0025] When using this device, the operator pours an appropriate amount of PVC granules into the protective shell 12. As the PVC granules pass through the protective shell 12, the battery 13 injects current into the electrode plate 14, generating a large static electricity on the electrode plate 14. This static electricity absorbs dust and impurities from the PVC granules, causing them to adhere to the electrode plate 14, thus achieving dust removal and preventing dust from affecting the subsequent use of the PVC granules. After the PVC granules have completely fallen into the first screening frame 4, the operator starts the dual-axis motor 5. The output shaft of the dual-axis motor 5 drives the cam 6 to rotate, causing the connecting rod 7 to move back and forth. The forward and backward movement of motor 7 drives the rotating shaft 8 and the second screening frame 9 to move back and forth. The forward and backward movement of the second screening frame 9 compresses the forward and backward movement of the first screening frame 4, causing the spring plate 3 to deform. This shakes the first screening frame 4 and the second screening frame 9, thus screening the PVC particles. Larger PVC particles are shaken into the second collection frame 22, while the smallest PVC particles fall into the second screening frame 9, and then from the second screening frame 9 into the first collection frame 10. After screening, the operator turns off the dual-axis motor 5, then removes the first collection frame 10 and the second collection frame 22, and then stores the first collection frame 10 and the second collection frame 22 separately.

[0026] Example: Based on Example 1, see [link to example]. Figure 4 As shown, it also includes an electric push rod 15 and a partition 16. The electric push rod 15 is installed on the rear side of the bottom of the support block 11 by means of bolt connection. The partition 16 is fixedly connected to the telescopic rod of the electric push rod 15 and slides within the support block 11.

[0027] When feeding materials, the operator starts the electric push rod 15. The telescopic rod of the electric push rod 15 moves the partition 16 forward, which blocks the outlet of the protective shell 12, thus preventing excessive PVC particles from overflowing the first screening frame 4. The operator then stops feeding materials. After screening, the operator controls the telescopic rod of the electric push rod 15 to retract, moving the partition 16 backward, so that the PVC particles in the protective shell 12 fall into the first screening frame 4 for screening. After screening, the operator turns off the electric push rod 15.

[0028] See Figure 5 As shown, it also includes a single-axis motor 17, a screw 18, a fixing rod 19, and a scraper 20. The single-axis motor 17 is installed on the rear right side of the bracket 1. The output shaft of the single-axis motor 17 is fixed to the screw 18 through a coupling. The fixing rod 19 is set in the lower left part of the bracket 1 by welding. The scraper 20 is slidably set on the fixing rod 19. The scraper 20 is threadedly connected to the screw 18. The scraper 20 is located above the first collection frame 10.

[0029] After the PVC particles are screened, the staff starts the single-axis motor 17. The output shaft of the single-axis motor 17 drives the screw 18 to rotate, which in turn moves the scraper 20 forward. The fixed rod 19 acts as a guide, which can scrape the PVC particles flat and prevent them from overflowing the first collection frame 10. After the PVC particles are scraped flat, the staff turns off the single-axis motor 17 and then collects the PVC particles in the first collection frame 10.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
