Common plastic granules include general-purpose plastics, engineering plastics, and special plastics. After the plastic granules are produced and formed, in order to ensure the specifications and quality of the plastic granules, the plastic granules need to be screened by size.

[0003] In the prior art, the most commonly used tool for screening plastic particles is a sieve, also known as a sieve plate; and the screening of plastic particles is different from the multi-stage screening of some industrial materials. It only needs to screen out the plastic particles that do not meet the small particle size; the existing screening devices currently have the problems of low unit screening amount and small screening area. In many cases, it is impossible to expand the screening device in a limited space, which affects the processing and discharge efficiency of plastic particles. Utility Model Content

[0005] Therefore, the purpose of the utility model is to provide a plastic particle screening device to solve the problems of low unit screening amount and small screening area in the existing screening devices mentioned in the above background technology. In many cases, it is impossible to expand the screening device in a limited space, thereby affecting the processing and discharge efficiency of plastic particles.

[0012] Compared with the prior art, the beneficial effect of the utility model is that when the material enters the screening tower box, the vibration mechanism drives the screening tower box to form a slight high-frequency vibration, so that the plastic particles on the screening plate and the screen can continuously jump, spread and roll linearly. In this process, qualified small-size plastic particles will fall into the material guide channel through the screen and flow into the material guide nozzle and the material guide cavity, and be discharged through the first discharge port, while unqualified large-size particles will naturally roll down to the leakage port with the screen, and then carry out the next layer of diversion screening. The lower the screening is, the less small and large particles of plastic there are, thereby greatly reducing the screening pressure of the equipment and improving the batch screening efficiency of materials. In summary, the plastic particle screening equipment not only greatly increases the material screening area and increases the unit screening amount, but also effectively reduces the space occupied by the on-site site, which is conducive to the efficient processing and discharge of plastic particles.

[0022] Figure 1-Figure 5 The schematic diagram of the whole structure of a plastic particle screening device of the utility model is shown. Figure 1-Figure 5A plastic particle screening device according to the present embodiment includes a support frame 100, a screening tower box 200 is vertically and elastically installed inside the support frame 100, and partitions 210 are provided on both sides of the screening tower box 200, and the two partitions 210 are screening cabins 220, and a material guide cavity 230 is provided between the two partitions 210 and the screening tower box 200, and a plurality of inclined screening plates 240 are arranged inside the screening cabin 220 along its height direction, and the upper inclined ends and lower inclined ends of adjacent screening plates 240 are close to each other, and the top of the screening plate 240 is It is covered with a screen 241, and a material guiding channel 242 is provided between the screening plate 240 and the screen 241. The lower inclined end of the material guiding channel 242 also has a material guiding nozzle 243 connected to the material guiding cavity 230, and avoidance ports are provided on both sides of the material guiding nozzle 243. The bottom of the screening tower box 200 is respectively provided with a first discharge port 2001 connected to the material guiding cavity 230, and a second discharge port 2002 connected to the screening cabin 220. A vibration component 300 is also provided on the top of the screening tower box 200, and a feed hopper 260 is also provided on one side of the top of the screening cabin 220.

[0023] There are also leakage ports 250 between the two sides of the material guide nozzle 243 and the inner wall of the screening tower box 200. The side of the partition 210 is also provided with a plurality of material guide ports 2101 respectively connected to the outer ends of the material guide nozzle 243. When screening is performed, qualified small-sized plastic particles will pass through the screen 241 and fall into the material guide channel 242, and flow to the material guide nozzle 243 and the material guide cavity 230 at the downward inclined end, while unqualified large-sized particles will naturally roll to the upper part of the material guide nozzle 243 with the screen 241, and slide sideways into the leakage port 250, and then the next layer of apportionment screening will be carried out. The lower the screening is, the less small and large plastic particles there are, thereby greatly reducing the screening pressure of the equipment and improving the efficiency of batch screening of materials.

[0024] It can be understood that by cleverly setting up several screening units in the height direction of the equipment, not only the material screening area is greatly increased and the unit screening amount is improved, but also the space occupied by the on-site site is effectively reduced, which is conducive to the efficient processing and discharge of plastic particles.

[0025] Furthermore, the vibration component 300 is a vibration motor, and a control board 310 electrically connected to the vibration component 300 is also provided on the outside of the support frame 100.

The upper end of the spring leg 410 is pressed against a support ear 420 connected to and fixed on the outer wall of the screening tower box 200. With the cooperation of a plurality of support ears 400, spring legs 410 and support ears 420, the screening tower box 200 can be stably suspended and installed on the support frame 100, and with the cooperation of the vibration component 300, the screening tower box 200 forms high-frequency vibration, so that the plastic particles on the screening plate 240 and the screen 241 can continuously jump, spread and roll linearly, and at the same time prevent the material from being blocked in the mesh.

[0027] Furthermore, a plurality of inspection doors 270 are provided on the outside of the screening tower box 200. By opening the inspection doors 270, the screening components in the screening tower box 200 can be conveniently installed, maintained and replaced, and different screening nets can be replaced according to actual screening needs.

Through the mutual cooperation of the base plate 500, the support frame 100 and the reinforcing beam 510, the entire equipment frame forms a rigid whole, which is more stable in use and operation.

[0029] In summary, in a plastic particle screening device according to the present embodiment, when the material enters the screening tower box 200 from the feed hopper 260, the vibration motor can drive the entire screening tower box 200 to form a slight high-frequency vibration with the cooperation of the elastic support frame, so that the plastic particles on the screening plate 240 and the screen 241 can continuously jump, spread and roll linearly. In this process, qualified small-size plastic particles will pass through the screen 241 and fall into the guide channel 242 and flow into the guide nozzle 243 and the guide cavity 230, and be discharged through the first discharge port 2001, while unqualified large-size particles will naturally roll down to the leakage port 250 with the screen 241, and then the next layer of diversion screening will be carried out. The lower the screening is, the less small-particle plastic and large-particle plastic there are, thereby greatly reducing the screening pressure of the equipment and improving the efficiency of batch screening of materials.
