Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pelletizing and screening devices, and in particular to a pelletizing and screening device for the production of modified nylon plastics. Background Technology
[0002] Plastic products are a general term for everyday and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of synthetic polymer materials with malleability. Together with synthetic rubber and synthetic fibers, they form the three essential synthetic materials for daily life. Specifically, plastics are materials made primarily of natural or synthetic resins, with various additives, which can be molded into specific shapes under certain temperature and pressure conditions and retain those shapes at room temperature.
[0003] For example, the authorization announcement number "CN211518143U" is titled "Plastic Strip Pelletizing and Screening Device for Modified Nylon Plastic Production". This pelletizing and screening device is reasonably designed, with a stabilizing foot in the shape of a trapezoid and a layer of anti-slip rubber pad bonded to the bottom to ensure the overall stability of the device. The length and width of the collection trough are larger than the screen, effectively collecting the finished product. The screen rotates synchronously with the rotating shaft through rollers, ensuring that the finished product can pass through the screen and fall into the collection trough. The screen is made of stainless steel wire mesh and has dense perforations to screen the finished product and ensure the service life of the screen. There are two cutters, which are symmetrically arranged on the left and right sides directly below the bottom outlet of the feed port.
[0004] The above-mentioned and existing technologies have the following drawbacks: Since the collection trough is located directly below the screen, the granular plastic will fall onto the inner wall of the screen during the falling process and be bounced off the screen to the outside of the screen, which will prevent the granular plastic from entering the collection trough and cause waste of plastic strip raw materials; at the same time, plastic residue will be generated after the plastic strip raw materials are granulated, and these residues attached to the screen will affect the screening effect of the screen. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pelletizing and screening device for the production of modified nylon plastics.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a pelletizing and screening device for modified nylon plastic production, including a workbench with multiple support legs on its lower surface, a first empty groove on the front surface of the workbench with a gantry at the upper end of the first empty groove, support blocks at the upper end of the gantry and the upper rear part of the workbench, a discharge port at the upper end of two of the support blocks, a hydraulic mechanism on one side of each of the two support blocks, a cutter on one side of each of the two hydraulic mechanisms, two rotating rollers between the front and rear inner walls of the workbench with screens covering their surfaces, a motor on the front surface of the workbench with its output shaft fixedly connected to one of the two rotating rollers, two symmetrical U-shaped blocks on the rear inner wall of the workbench with a slidable collection trough between the two U-shaped blocks, the collection trough being located inside the screen and directly below the discharge port, a bearing block on the lower right side surface of the two right support legs with a slag collection trough on its upper surface, and a cleaning device between the two right support legs.
[0008] Preferably, the lower surfaces of the two U-shaped blocks are provided with a second groove, and multiple sliding wheels are rotatably connected to the inner walls on both sides of the two second grooves.
[0009] Preferably, the front surface of the collection trough is provided with a panel, and the front surface of the panel is provided with a handle.
[0010] Preferably, the upper surface of each of the two U-shaped blocks is provided with an iron block, and the upper surface of the panel is provided with two magnets that match the iron blocks.
[0011] Preferably, the cleaning device includes a brush holder disposed between the two support legs on the right side, and the upper surface of the brush holder is provided with a plurality of bristles, all of which are in contact with the screen surface.
[0012] Preferably, the two support feet on the right side are provided with strip-shaped through holes, and the front and rear surfaces of the brush holder are provided with lead screws. The opposite ends of the two lead screws pass through the strip-shaped through holes and are threaded with nuts.
[0013] This invention proposes a pelletizing and screening device for modified nylon plastic production. The advantages are as follows: Because the collection trough is located inside the screen and directly below the feed inlet, the granular plastic, during its descent, passes through a single screen and falls directly into the collection trough. This avoids the granules falling onto the inner wall of the screen and being bounced off, ensuring the finished granular plastic smoothly enters the collection trough and saving raw plastic strips. Simultaneously, any residue adhering to the screen is scraped off by the brush and falls into the residue collection trough, preventing it from affecting the screening effect of the screen.
