Description

Technical Field

[0001] The utility model belongs to the technical field of pelletizers, and particularly relates to a novel water-ring pelletizer. Background Art

[0002] Plastic pelletizers are mainly used for processing waste plastic products such as waste plastic films, woven bags, agricultural convenience bags, basins, buckets, beverage bottles, furniture, and daily necessities. After these waste plastics are pretreated by classification, crushing, cleaning, etc., they can be shredded into particles of a certain specification through the processing of a plastic pelletizer, and then used for plastic recycling or other plastic processing processes.

[0003] For example, a Chinese patent with the publication number CN220280168U discloses a horizontal water-ring hot pelletizer, which includes a pelletizer body and also includes a bottom plate. The pelletizer body is installed at the top end of the bottom plate. A water ring is fixedly connected to the left end of the pelletizer body. A first motor is fixedly connected to the left end of the water ring. The output end of the first motor penetrates through the water ring and is fixedly connected to a tool rest. Discharge ports are provided on both the water ring and the bottom plate. A sieve box is slidably connected to the bottom end of the bottom plate. A second motor is installed at the bottom end of the bottom plate through a fixing frame. The output end of the second motor is fixedly connected to a power rod. The other end of the power rod is rotatably connected to a connecting rod. The other end of the connecting rod is rotatably connected to the right end of the sieve box. A bottom box is fixedly connected to the bottom end of the bottom plate, and a screening mechanism is installed at the rear end of the bottom box.

[0004] The above water-ring pelletizer is convenient for separating qualified products from unqualified products, improving the appearance of qualified products, and has high use flexibility. However, there are still some deficiencies in this water-ring pelletizer that need to be improved. Although the water flow is used to guide the cut plastic to fall smoothly, in actual operation, there are still occasionally a small amount of plastic particles adhering to the inner wall of the annular pelletizer, which will affect the overall material discharge smoothness and efficiency, and may also cause a slight blockage of the production line. In addition, the flow state of the plastic particles in the water does not reach the most ideal state, and some particles fail to fully utilize the scouring of the water flow, reducing the cooling and cleaning effects of the plastic particles.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] Embodiment

[0024] Refer to Figures 1 to 5, a novel water ring pelletizer described in this embodiment includes a base 1. A pelletizer body 2 is fixedly connected to the upper end of the base 1. A forming plate 3 is fixedly connected inside the pelletizer body 2. One end of the forming plate 3 is rotatably connected to a tool rest 4. One side of the tool rest 4 is fixedly connected to a mounting plate 8. One end of the mounting plate 8 is fixedly connected to a spring 6. A telescopic tube 7 is fixedly connected to the mounting plate 8 inside the spring 6. A common end of the spring 6 and the telescopic tube 7 is fixedly connected to a scraping plate 5. When the scraping plate 5 is worn, it can also closely adhere to the inner wall of the pelletizer body 2 under the action of multiple springs 6. One end of the mounting plate 8 away from the scraping plate 5 is fixedly connected to a stirring assembly 10. One side of the scraping plate 5 is in fitting connection with the inner wall of the pelletizer body 2. A driving assembly 11 is provided on one side of the pelletizer body 2. One side of the lower end of the pelletizer body 2 is fixedly connected to a diversion pipe 15, and one side of the diversion pipe 15 penetrates through the base 1. One end of the pelletizer body 2 away from the diversion pipe 15 is fixedly connected to a water inlet pipe 12. The water inlet pipe 12 extends into the pelletizer body 2. Since it is on the side of the scraping plate 5, it will not affect the water outlet work of the water inlet pipe 12. It should be added that an extrusion device is installed on one side of the pelletizer body 2 away from the tool rest 4. The extrusion device is composed of a cylinder and a push plate, etc., and can push the plastic to be cut through the forming plate 3. A sieve plate is installed in the base 1. The plastic pellets fall onto the sieve plate, and the water flow re-enters the base 1. These are all technical means in the reference documents and are common structural settings on the pelletizer. Since there is no innovation in the technical solution, it will not be repeated here.

The sliding rod 71 and the fixed tube 72 are both inside the spring 6. By setting the fixed tube 72 and the sliding rod 71, when the scraping plate 5 moves under the action of the spring 6, the sliding rod 71 moves inside the fixed tube 72, keeping the position of the scraping plate 5 stable without deviation, ensuring the efficient scraping work of the scraping plate 5.

[0026] Reference Figure 3 , a rubber sleeve 81 is fixedly connected between the scraping plate 5 and the mounting plate 8, and the rubber sleeve 81 covers the spring 6. By connecting the rubber sleeve 81 between the scraping plate 5 and the mounting plate 8, it can prevent plastic pellets from entering the inside of the spring 6. The shape of the edge of the rubber sleeve 81 is arc-shaped. Since rubber has good extensible elasticity, it does not affect the movement of the scraping plate 5 under the action of the spring 6.
