Description

Technical Field

[0001] This utility model relates to the field of plastic particle impurity removal technology, and in particular to a plastic particle impurity removal device. Background Technology

[0002] In the plastic recycling and processing industry, recycled plastic fragments or plastic particles generated during production often contain various unwanted impurities. The core function of plastic particle removal equipment is to efficiently separate target plastic particles from impurities by screening according to the physical size of the material particles, or to classify plastic particles of different sizes, thereby obtaining pure, uniform, high-quality raw materials that meet the quality requirements of subsequent processing.

[0003] However, it's worth considering that traditional planar vibrating screens are typically equipped with single or multiple layers of filters at fixed inclination angles. Their screening efficiency heavily depends on the inclination angle of the filters and the vibration parameters. However, when processing different types, sizes, moisture content, or flow rates of plastic particles, a fixed filter angle often fails to achieve optimal screening results. If the angle is too small, the material flow is slow, resulting in low screening efficiency and easy clogging of the filters. If the angle is too large, the material flow rate is too fast, leading to insufficient screening, and qualified small particles may be carried away before passing through the screen, resulting in decreased screening accuracy.

[0004] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a plastic particle impurity removal device to solve the problem that when processing plastic particles of different types, sizes, moisture content, or flowability, a fixed filter screen angle often cannot achieve the best screening effect.

[0006] To achieve the above objectives, this utility model provides a plastic particle impurity removal device, including a base, a platform above the base, a vibration unit that cooperates with the base installed on the platform, two side plates fixedly connected to the top of the platform, a guide plate between the two side plates, and several filter screens above the guide plate. The guide plate and the filter screens are both inclined, and the inclination angles of two adjacent filter screens are opposite.

[0007] One end of the filter screen and the guide plate are rotatably connected to the side plate, and the other end of the filter screen and the guide plate are fixedly connected to the support shaft. An adjustment component for adjusting the position of the support shaft is installed on the platform. Several guide hoppers that cooperate with the filter screen and the guide plate are provided above the platform. The several guide hoppers are located on both sides of the side plate, and the guide hoppers and the side plate are fixedly connected.

[0008] Preferably, the adjustment assembly includes two sets of adjustment units disposed above the stage. Each set of adjustment units includes two adjustment seats, and the two ends of the support shaft are rotatably connected to the two adjustment seats respectively. A first lead screw is fixedly connected to the bottom of the adjustment seat. A threaded sleeve is sleeved on the outside of the first lead screw. A fixed plate is fixedly connected to the bottom end of the threaded sleeve. A presser for pressing the fixed plate is installed on the stage.

[0009] Preferably, the presser includes a pressing plate disposed above the fixed plate, the pressing plate having a rectangular hole that mates with a threaded sleeve, the threaded sleeve passing through the corresponding rectangular hole, a plurality of second lead screws passing through the pressing plate, the bottom end of the second lead screws being fixedly connected to the platform, and a nut located above the pressing plate being sleeved on the outside of the second lead screws.

[0010] Preferably, a plurality of positioning plates are provided above the pressing plate, and positioning holes that cooperate with nuts are provided on the positioning plates. A reset component that cooperates with the positioning plates is installed on the platform.

[0011] Preferably, the resetting component includes several fixed frames fixedly installed on the platform, several movable columns are fixedly connected to the top of the positioning plate, the movable columns pass through the corresponding fixed frames, and a first spring is sleeved on the outside of the movable columns. The two ends of the first spring are fixedly connected to the positioning plate and the fixed frames, respectively.

[0012] Preferably, the vibration unit includes several vibration motors fixedly installed on the bottom of the platform, several positioning columns are fixedly connected to the bottom of the platform and the top of the base, the base and the platform are connected by several second springs, and the two ends of the second springs are respectively sleeved on the outside of two adjacent positioning columns, and an anti-slip pad is fixedly connected to the bottom of the base.

[0013] The beneficial effects of this invention are as follows: Based on the screening requirements of plastic particles, the operator adjusts the position of the support shaft by adjusting the components. The support shaft drives the filter screen to rotate relative to the side plate, changing the tilt angle of each filter screen. The vibration unit is activated, causing the platform to vibrate relative to the base. The operator pours the plastic particles to be screened onto the top filter screen. Plastic particles smaller than the filter holes on the screen fall onto the next filter screen or the guide plate, while plastic particles larger than the filter holes roll from the screen onto the corresponding guide hopper, where they are discharged as screened plastic particles or impurities. For materials with good flowability and easy screening, the angle of the filter screen can be increased to improve flow rate and processing capacity. For damp, statically charged, or difficult-to-screen materials close to the filter hole size, the angle can be decreased to reduce flow rate and extend the residence time of the material on the filter screen, ensuring that every qualified particle has ample opportunity to pass through the filter holes. This greatly improves screening accuracy and efficiency. One device can handle different types, sizes, and moisture levels of plastic particles without the need to replace filter screens or the entire device. Attached Figure Description

[0023] This specification provides one or more embodiments of a plastic particle removal device, such as... Figure 1 As shown, it includes a base 1, a platform 2 is provided above the base 1, a vibration unit that cooperates with the base 1 is installed on the platform 2, two side plates 3 are fixedly connected to the top of the platform 2, a guide plate 24 is provided between the two side plates 3, and several filter screens 4 are provided above the guide plate 24. The guide plate 24 and the filter screens 4 are both inclined, and the inclination angles of two adjacent filter screens 4 are opposite.

[0024] One end of the filter screen 4 and the guide plate 24 are rotatably connected to the side plate 3, and the other end of the filter screen 4 and the guide plate 24 are fixedly connected to the support shaft 5. An adjustment assembly for adjusting the position of the support shaft 5 is installed on the platform 2. Several guide hoppers 6, which cooperate with the filter screen 4 and the guide plate 24 respectively, are located on both sides of the side plate 3, and the guide hoppers 6 are fixedly connected to the side plate 3. According to the screening requirements of the plastic particles, the operator adjusts the position of the support shaft 5 through the adjustment assembly. The support shaft 5 drives the filter screen 4 to rotate relative to the side plate 3, changing the position of the support shaft 5. The tilt angle of each filter screen 4 activates the vibration unit, causing the platform 2 to vibrate relative to the base 1. The operator pours the plastic particles to be screened onto the top filter screen 4. Plastic particles smaller than the filter holes on the filter screen 4 fall onto the next filter screen 4 or the guide plate 24, while plastic particles larger than the filter holes on the filter screen 4 roll off the filter screen 4 onto the corresponding guide hopper 6, where they are discharged as screened plastic particles or impurities. For materials with good flowability and easy screening, the angle of the filter screen 4 can be increased to improve the flow rate and increase processing capacity. For damp, statically charged, or difficult-to-screen materials that are close to the filter hole size, the angle can be decreased to reduce the flow rate and extend the residence time of the material on the filter screen 4, thus ensuring that every qualified particle has a sufficient chance to pass through the filter holes, greatly improving screening accuracy and efficiency. One machine can handle different types, sizes, and moisture levels of plastic particles without the need to replace the filter screens 4 or the machine itself.

[0025] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the adjustment assembly includes two sets of adjustment units disposed above the stage 2. Each set of adjustment units includes two adjustment seats 7, and the two ends of the support shaft 5 are rotatably connected to the two adjustment seats 7 respectively. A first lead screw 8 is fixedly connected to the bottom of the adjustment seat 7, and a threaded sleeve 9 is sleeved on the outside of the first lead screw 8. A fixed plate 10 is fixedly connected to the bottom end of the threaded sleeve 9. A presser for pressing the fixed plate 10 is installed on the stage 2. The presser includes a pressing plate 23 disposed above the fixed plate 10. A rectangular hole 11 is opened on the pressing plate 23 to cooperate with the threaded sleeve 9, and the threaded sleeve 9 passes through the corresponding rectangular hole 11. A plurality of second lead screws 12 are threaded through the pressing plate 23. The bottom end of the second lead screws 12 is fixedly connected to the platform 2. Nuts 13 located above the pressing plate 23 are sleeved on the outside of the second lead screws 12. A plurality of positioning plates 14 are provided above the pressing plate 23. Positioning holes 15 are provided on the positioning plates 14 to cooperate with the nuts 13. Reset components that cooperate with the positioning plates 14 are installed on the platform 2. The reset components include a plurality of fixing brackets 16 fixedly installed on the platform 2. A plurality of movable columns 17 are fixedly connected to the top of the positioning plates 14. The movable columns 17 pass through the corresponding fixing brackets 16. The outside of the movable columns 17 A first spring 18 is fitted, with its two ends fixedly connected to the positioning plate 14 and the fixing frame 16, respectively. The operator drives the threaded sleeve 9 to rotate, causing the threaded sleeve 9 to move relative to the first lead screw 8, thus changing the height of the adjusting seat 7. The adjusting seat 7 can then change the angle of the filter screen 4 via the support shaft 5. The threaded sleeve 9 and the fixing plate 10 slide horizontally relative to the rectangular hole 11 and the pressing plate 23, respectively. After the position of the adjusting seat 7 is adjusted, the operator drives the positioning plate 14 and the movable column 17 to move upward relative to the fixing frame 16, and the first spring 18 is in a compressed state, causing the nut 13 to disengage from the positioning hole 1. 5. Release the restriction on the position of nut 13. The operator drives nut 13 to rotate. Nut 13 rotates relative to the second lead screw 12. Nut 13 applies downward pressure to the pressing plate 23. The pressing plate 23 applies downward pressure to the fixed plate 10, so that the threaded sleeve 9 and the fixed plate 10 are fixed relative to the platform 2. Then the operator releases the positioning plate 14. The first spring 18 drives the positioning plate 14 and the movable column 17 to move down. The positioning hole 15 is sleeved on the outside of nut 13. The positioning plate 14 and the positioning hole 15 limit the position of nut 13, preventing nut 13 from rotating and shaking relative to the second lead screw 12 due to non-human factors.

[0026] In embodiments of this utility model, such as Figure 1 and Figure 4As shown, the vibration unit includes several vibration motors 19 fixedly installed at the bottom of the platform 2. Several positioning columns 20 are fixedly connected to the bottom of the platform 2 and the top of the base 1. The base 1 and the platform 2 are connected by several second springs 21, and the two ends of the second springs 21 are respectively sleeved on the outside of two adjacent positioning columns 20. An anti-slip pad 22 is fixedly connected to the bottom of the base 1. Through the design of the positioning columns 20 and the second springs 21, the platform 2 is elastically connected to the base 1. When the vibration motors 19 are started, the platform 2 vibrates relative to the base 1, which makes it easier for plastic particles or impurities on the filter screen 4 and the guide plate 24 to roll onto the corresponding guide hopper 6. Through the design of the anti-slip pad 22, the possibility of the base 1 sliding relative to the ground is reduced.
