Description

Technical Field

[0001] The utility model belongs to the technical field of filter screen plates for pelletizers, in particular to a high-efficiency filter screen plate for pelletizers. Background Art

[0002] A pelletizer is a mechanical device used to cut polymer materials such as plastics, rubber, chemical raw materials or other block or strip materials into granules.

[0003] The filter screen is installed at the discharge port of the pelletizer. The filter screen on the common pelletizer is usually fixed with screws during installation. The personnel need to use a screwdriver during installation. The filter screen is located at the bottom of the pelletizer, which is not convenient for using a screwdriver. This makes it more troublesome for personnel to install the filter screen. In addition, after the filter screen is used, the inner wall of the circular hole on the filter screen will be sticky with plastic melt, and the plastic melt will agglomerate when it is cooled, which will affect the next use of the filter screen. In general, the circular hole diameter on the filter screen is 5mm. Due to the excessive melt pressure during the production process, the plastic melt has low permeability, which affects the production capacity. In view of this, we propose a high-efficiency filter screen for a pelletizer. Utility Model Content

[0007] A disc, the disc is rotatably mounted on the bottom of the filter plate, a plurality of movable grooves are provided in the disc, a plurality of movable grooves are slidably mounted with movable rods, and the bottom ends of the plurality of movable rods respectively penetrate the bottoms of the plurality of movable grooves and are fixedly mounted with the same extrusion plate;

[0008] An elastic component is located at the bottom of the disc and is used for squeezing the squeezing plate.

[0009] In the technical scheme, the top of the filter plate is inserted into the discharge port of the pelletizer body by setting two clamping blocks. At this time, the top of the filter plate will squeeze the two clamping blocks, so that the two clamping blocks are respectively moved away from each other in the two sliding grooves. At the same time, the movement of the clamping blocks in the sliding grooves will squeeze the two springs to shrink. When the top of the filter plate completely enters the discharge port of the pelletizer body, under the action of the rebound force of the four springs, the four springs will squeeze the two clamping blocks respectively, so that the two clamping blocks are respectively close to each other in the two sliding grooves, until one side of the two clamping blocks is fully inserted into the limiting groove. At this time, the two clamping blocks can limit the filter plate, ensuring that it is convenient for personnel to install the filter plate. No tools are required during installation, which is convenient for personnel to operate.

[0010] The extrusion plate is provided to squeeze the extrusion plate upward, and the upward movement of the extrusion plate will drive the plurality of moving rods to move upward.

[0011] By setting a circular hole with a diameter of 6mm, the back pressure can be reduced, the plastic melt passability can be increased, and the production efficiency can be improved.

[0013] A plurality of sliding rods are fixedly mounted on the bottom of the disc and located at the edge of the disc, the bottom ends of the plurality of sliding rods penetrate the extrusion plate, and a spring 2 is sleeved on the plurality of sliding rods and located between the disc and the extrusion plate.

[0014] In the present technical solution, the extrusion plate is squeezed upward, and the upward movement of the extrusion plate will drive the plurality of moving rods to move upward. At the same time, the upward movement of the extrusion plate will squeeze the plurality of springs 2 to contract. At this time, the moving rod will move upward in the moving groove, and the top ends of the plurality of moving rods will be respectively inserted into the plurality of circular holes. At this time, the top ends of the plurality of moving rods can respectively scrape off the plastic melt sticking on the inner walls of the plurality of circular holes. After the scraping is completed, under the action of the rebound force of the plurality of springs 2, the plurality of springs 2 will squeeze the extrusion plate to move downward. The downward movement of the extrusion plate will drive the plurality of moving rods to reset. At the same time, the plurality of sliding rods will slide in the extrusion plate to ensure that the plastic melt sticking on the inner walls of the plurality of circular holes can be cleaned, and to ensure that no plastic melt will remain on the inner walls of the plurality of circular holes when the filter plate is used next time.

[0015] In the above technical solution, further, the sliding rod is slidably connected to the extrusion plate, and the two ends of the second spring are tightly welded to the bottom of the disc and the top of the extrusion plate respectively.

[0016] In this technical solution, it is ensured that the sliding rod can slide normally in the extrusion plate, thereby ensuring the structural stability of the second spring.

[0017] In the above technical solution, further, the two clamping blocks are symmetrically arranged, one side of the clamping block is plug-fitted with the limiting groove, and one side of the clamping block is an inclined structure.

[0018] In this technical solution, it is ensured that the two clamping blocks can clamp the filter plate, that one side of the clamping block can be inserted into the limiting groove, and that the top of the filter plate moves upward to squeeze the clamping block to move.

[0072] Working principle: When using this device, the personnel can first insert the top of the filter plate 2 into the discharge port of the pelletizer body 1. At this time, the top of the filter plate 2 will squeeze the two clamping blocks 5, so that the two clamping blocks 5 are respectively separated from each other in the two sliding grooves 4. At the same time, the movement of the clamping blocks 5 in the sliding grooves 4 will squeeze the two springs 6 to shrink. When the top of the filter plate 2 completely enters the discharge port of the pelletizer body 1, under the action of the rebound force of the four springs 6, the four springs 6 will squeeze the two clamping blocks 5 respectively, so that the two clamping blocks 5 are respectively close to each other in the two sliding grooves 4, until one side of the two clamping blocks 5 is fully inserted into the limiting groove 3. At this time, the two clamping blocks 5 can limit the filter plate 2, ensuring that it is convenient for personnel to install the filter plate 2. No tools are required during installation, which is convenient for personnel to operate.

[0073] When the overall device is used, the inner walls of the plurality of circular holes 13 will be adhered to the plastic melt, and the plastic melt will agglomerate when it is cooled. At this time, the personnel can immediately rotate the disc 7 until the center of the disc 7 coincides with the center of the filter plate 2, and the personnel can squeeze the extrusion plate 10 upward. The upward movement of the extrusion plate 10 will drive the plurality of moving rods 9 to move upward. At the same time, the upward movement of the extrusion plate 10 will squeeze the plurality of springs 12 to contract. At this time, the moving rod 9 will move upward in the moving groove 8, and the top ends of the plurality of moving rods 9 will be respectively inserted into the plurality of circular holes 13. At this time, the top ends of the plurality of moving rods 9 can respectively scrape off the plastic melt adhered to the inner walls of the plurality of circular holes 13. After the scraping is completed, under the action of the rebound force of the plurality of springs 12, the plurality of springs 12 will squeeze the extrusion plate 10 to move downward, and the extrusion plate 10 moves downward. The movement will drive several moving rods 9 to reset, and several sliding rods 11 will slide in the extrusion plate 10. The scraped plastic melt will remain on the filter plate 2, ensuring that the plastic melt sticking to the inner walls of several circular holes 13 can be cleaned, and ensuring that no plastic melt will remain on the inner walls of several circular holes 13 when the filter plate 2 is used next time. Then the personnel can press the two clamping blocks 5 to make the two clamping blocks 5 move away from each other in the two sliding grooves 4 respectively. At the same time, the movement of the clamping blocks 5 in the sliding grooves 4 will squeeze the two springs 6 to shrink. When one side of the two clamping blocks 5 is moved out of the limiting groove 3, the two clamping blocks 5 can release the limit of the filter plate 2. At this time, the personnel can remove the filter plate 2 from the discharge port of the pelletizer body 1, and then use a scraper to scrape and clean the filter plate 2 remaining on the filter plate 2.

[0074] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
