Technical Field

[0002] In the production of plastic granules for cable sheaths, after the raw materials are melted and mixed, they are fed into the lower-stage twin-screw extruder. The lower-stage twin-screw extruder extrudes and granulates the melt under low speed, high pressure and cooling conditions. Then, the granules are air-cooled and hot-cut from the die. The granules cut off by the air-cooled die are cooled by a two-stage air-cooled cyclone separator, and the particle temperature drops to 35-40℃. Then, they are cooled to room temperature by an air-cooled extended vibrating screen before being packaged as finished products.

[0003] In the Chinese patent with publication number CN 216068210 U, a hydraulic lifting device is used to drive the support frame to move up and down reciprocally. The support frame drives the vibrating screen to move up and down reciprocally. Combined with the vibration device, the vibrating screen moves forward and backward reciprocally, thereby realizing the screening function of materials, accelerating the vibration speed and improving the screening quality. The screened materials fall into the storage box. The materials falling from the left and right ends of the vibrating screen fall onto the guide plate for easy cleaning.

[0004] However, the above-mentioned device has the following problems during use: the screen is affected by the hydraulic lifting device during the shaking process, its shaking is hindered, the shaking amplitude of the entire screen and plastic particles is low, and the effect of screening plastic particles is poor.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-5 A vibrating screen for air-cooled die-cutting particles includes a shell 1 and a screen 6. The shell 1 includes multiple intermediate cylinders 101 and a top cylinder 104. The top cylinder 104 is located on the upper side of the intermediate cylinders 101. The multiple intermediate cylinders 101 are stacked in layers. A discharge pipe is installed at the top intermediate cylinder 101, and a discharge pipe 105 is installed in the bottom intermediate cylinder 101. The discharge pipe 105 is shaped like a funnel, and a feed pipe is provided in the top cylinder 104.

[0025] During cable material production, the material is mixed in a high-speed mixer and fed into a mixer. The mixer heats the material to a molten state and mixes it evenly. The mixed material then enters the plastic granule extruder, where it is extruded and granulated under low speed, high pressure, and cooling conditions. The granules are then hot-cut by an air-cooled die. The granules cut off by the air-cooled die are cooled by a two-stage air-cooled cyclone separator. After cooling, the plastic granules enter the shell 1 from the feed pipe at the top of the top cylinder 104 and are screened by a screen 6. The screen 6 removes larger plastic granules, and the qualified plastic granules are discharged from the discharge pipe 105 at the bottom. These plastic granules are subsequently collected, packaged, and transported.

[0026] More specifically, hook-shaped outer rings 102 are fixedly installed on the outer walls of the intermediate cylinder 101 and the top cylinder 104. Hook-shaped outer rings 102 are provided at both the top and bottom of the top cylinder 104. The hook-shaped outer ring 102 is provided at the bottom of the top cylinder 104. The hook-shaped outer ring 102 includes an annular part and a hook-shaped part. The annular part is a plane. When the intermediate cylinders 101 are connected to each other or between the intermediate cylinders 101 and the top cylinder 104, the annular part serves to make planar contact, so that the upper and lower distributed intermediate cylinders 101 and top cylinder 104 can be stably distributed on the upper side of the base 2. A clamping ring 103 is engaged at the hook-shaped outer ring 102. The clamping ring 103 is engaged on the outside of the upper and lower hook-shaped outer rings 102 to fix the position of the upper and lower hook-shaped outer rings 102, thereby realizing the clamping and fixing work between multiple intermediate cylinders 101 and top cylinders 104. The entire housing 1 adopts a detachable connection, and the disassembly, repair, maintenance and cleaning of the components are relatively convenient.

[0027] Furthermore, the housing 1 is connected to a vibration motor 4 for driving its shaking. Specifically, two symmetrically distributed vibration motors 4 are installed on one of the intermediate cylinders 101. During the rotation of the vibration motors 4, the entire housing 1 will shake. In order to prevent the base 2 in contact with the ground from shaking significantly, multiple strong springs 3 are installed between the housing 1 and the base 2. The strong springs 3 are installed at the four corners of the base 2. More specifically, the strong springs 3 are inserted into the bottom rod and the top rod on the upper and lower sides respectively. The bottom rod is fixedly installed on the base 2, and the top rod is fixedly installed on the housing 1.

[0028] Furthermore, the screen 6 is designed with an arc shape that is raised in the middle and concave on the outside. The highest point of the screen 6 is closer to the feed pipe than its lowest point. The lowest point of the upper surface of the screen 6 is higher than the lowest edge of the discharge pipe. This is to ensure that the large particles screened by the screen 6 can be discharged from the discharge pipe. When the plastic particles fall from the feed pipe onto the upper surface of the screen 6, they shake on the screen 6 as the vibrating motor 4 drives it to shake. Small plastic particles fall through the screen holes, while large plastic particles are discharged through the discharge pipe.

[0029] Furthermore, such as Figure 3-5As shown, the screen 6 and the housing 1 are detachably connected via a shrinking mechanism 7. The screen 6 is fixedly mounted on a fixed frame, which has several telescopic grooves. A telescopic frame 701 is slidably mounted in each telescopic groove. The telescopic frame 701 is connected to the inner wall of the telescopic groove via a shrinking spring 702. Two symmetrically distributed shrinking plates 703 are installed inside the telescopic frame 701. The connecting groove 704 in the shrinking plate 703 is rotatably connected to the first rotating shaft 705. The shrinking plate 703 has two states: a shrunken state and an unfolded state. In the unfolded state, the shrinking plate 703 abuts against the outer wall of the housing 1. In the shrunken state, the shrinking plate 703... The retractable plate 703 is rotatably connected to the pull-out plate 706, which in turn is rotatably connected to the movable seat. The movable seat is rotatably connected to the movable rod 707, which is threadedly connected to the telescopic frame 701. When the movable rod 707 rotates, it can drive the movable seat to move. The movable seat drives the retractable plate 703 to rotate around the first rotating shaft 705 via the pull-out plate 706, allowing the retractable plate 703 to flow between the retracted and extended states. When the retractable plate 703 is in the retracted state, the entire telescopic frame 701 can be pushed into the housing 1, at which point the screen 6 can be removed from the intermediate cylinder 101.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
