Description

Technical Field

[0001] This utility model relates to the field of recycled plastic pellet production technology, specifically a recycled plastic pellet screening device. Background Technology

[0002] Recycled plastic pellets are plastic pellets made by recycling used virgin materials or waste plastics and processing them. Specifically, recycled plastic pellets are plastic pellets made by recycling waste plastics, processing them through a screw press, and then cutting them into pellets through a pelletizer. When screening impurities in recycled plastic pellets, a recycled plastic pellet screening device is required.

[0003] The recycled plastic pellet screening device effectively screens the pellets using a screen inside the container.

[0032] Example 1

[0033] This embodiment provides a technical solution: a recycled plastic pellet screening device, such as... Figures 1-5 As shown, it includes a feeding rack, a swing screening mechanism, a detachable screening mechanism, a screening positioning mechanism, and a belt conveyor 3.

[0034] The oscillating screening mechanism is installed and connected to the feeding rack. The oscillating screening mechanism can oscillate left and right on the feeding rack. The detachable screening mechanism is installed and connected to the inner side of the lower end of the oscillating screening mechanism. The recycled plastic particles inside the oscillating screening mechanism pass through the mesh of the detachable screening mechanism, so that they can be effectively oscillated left and right for screening. The screening positioning mechanism is installed and connected to both sides of the oscillating screening mechanism. The oscillating screening mechanism can be effectively positioned by the screening positioning mechanism when oscillating left and right for screening, so that it is more stable during oscillating screening and more accurate when screening and discharging. This facilitates efficient left and right oscillating screening. The inner end of the screening positioning mechanism is installed on the feeding rack, so that it can be placed stably. The belt conveyor 3 is located below the oscillating screening mechanism. The recycled plastic particles that fall from the oscillating screening mechanism can fall onto the belt conveyor 3, and then be transported to the designated location for collection by the belt conveyor 3.

[0035] The feeding rack includes a four-hole mounting plate 21 and an assembly screw tube 23. A support plate 2 is fixedly connected to the upper middle of the four-hole mounting plate 21. The support plate 2 is fixed in a designated position by screws through the four-hole mounting plate 21 at its lower end. An outer horizontal plate 24 and an assembly screw tube 23 are fixedly connected to the inner side of the upper end of the support plate 2. The outer horizontal plate 24 can be suspended in the air. A feeding valve 25 is installed on the inner side of the front end of the outer horizontal plate 24. The feeding valve 25 facilitates the feeding of materials into the recycled plastic granule collection box 4 below. The upper end of the feed valve 25 is equipped with a flange connecting pipe 22, which is connected to the external recycled plastic granule adding pipe. The material conveyed by the external recycled plastic granule adding pipe can be discharged into the flange connecting pipe 22, and then conveyed to the feed valve 25 through the flange connecting pipe 22. The front end of the assembly screw pipe 23 is equipped with a screening positioning mechanism, which facilitates the screw rotation installation. The inner side of the support plate 2 is equipped with a swing screening mechanism, which can be stably placed on the support plate 2.

[0036] like Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the screening positioning mechanism includes a connecting screw head 55 that is rotatably threaded onto the assembly screw tube 23. The connecting screw head 55 facilitates screw rotation for installation and removal. A positioning round rod 52 is fixedly connected to the front end of the connecting screw head 55. After installation, the connecting screw head 55 can drive the positioning round rod 52 for placement. A positioning sleeve 53 is sleeved around the periphery of the positioning round rod 52. The positioning sleeve 53 can be positioned and moved on the positioning round rod 52. A T-shaped connecting seat 54 is fixedly connected to the inner end of the positioning sleeve 53. The positioning sleeve 53 can drive the T-shaped connecting seat 54 to move. 54 can drive the recycled plastic granule collection box 4 to move stably, so that the recycled plastic granule collection box 4 can be positioned stably and swing left and right for screening. The front end of the positioning rod 52 is sleeved with a contact spring 5. When the recycled plastic granule collection box 4 contacts the contact spring 5, it can effectively elastically resist, making the recycled plastic granule collection box 4 more stable and convenient when it swings back. The outer ends of the positioning rod 52 and the contact spring 5 are fixed with a blocking disc 51. The contact spring 5 plays an elastic blocking role through the blocking disc 51 on the positioning rod 52.

[0037] The outer end of the recycled plastic pellet collection box 4 is connected to the T-shaped connector 54 by screws, which makes it easy to install and remove. When the recycled plastic pellet collection box 4 is moved, it can drive the T-shaped connector 54 to move as well. A rubber pad is installed between the recycled plastic pellet collection box 4 and the T-shaped connector 54, which makes the fixation tighter and more secure.

[0038] The oscillating screening mechanism includes an electric telescopic cylinder 1. The telescopic rod of the electric telescopic cylinder 1 can extend and retract. A screw mounting plate 11 is fixed to the periphery of the electric telescopic cylinder 1. The electric telescopic cylinder 1 is installed and connected to the support plate 2 through the screw mounting plate 11, so that the electric telescopic cylinder 1 can be stably installed and extended and retracted. The telescopic rod of the electric telescopic cylinder 1 passes through the support plate 2 and is installed with a recycled plastic granule collection box 4. When the telescopic rod of the electric telescopic cylinder 1 extends and retracts, it can drive the recycled plastic granule collection box 4 to move left and right, so that the recycled plastic granule collection box 4 can swing left and right for screening. The recycled plastic granule collection box 4 has a collection cavity 41 inside, so that recycled plastic granule material can be stored. A detachable screening mechanism is installed on the inner side of the lower end of the recycled plastic granule collection box 4, so that screening can be performed through the screening screen 45 of the detachable screening mechanism.

[0039] In use, the personnel place the recycled plastic granules to be screened into the recycled plastic granule collection box 4 of the oscillating screening mechanism, and then it falls onto the screening screen 45 of the detachable screening mechanism. When the electric telescopic cylinder 1 of the oscillating screening mechanism extends and retracts, it can drive the recycled plastic granule collection box 4 to move left and right. When the recycled plastic granule collection box 4 moves, it can be effectively positioned by the screening positioning mechanism, making the recycled plastic granule collection box 4 more stable during oscillating screening. The recycled plastic granules inside the recycled plastic granule collection box 4 can be effectively screened through the mesh of the screening screen 45 of the detachable screening mechanism. The recycled plastic granules that fall off the screen can fall onto the belt conveyor 3. In this way, the recycled plastic granule collection box 4 can accurately drop the material after being positioned by the screening positioning mechanism. This positioning by the screening positioning mechanism facilitates efficient left and right oscillating screening.

[0040] Example 2

[0041] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figures 1-3 As shown, to further better realize this utility model, the following configuration is specifically adopted: The detachable screening mechanism includes a U-shaped frame 43 sleeved inside the recycled plastic granule collection box 4, which facilitates installation and removal. A screening screen 45 is installed in the middle of the inner side of the U-shaped frame 43. The U-shaped frame 43, through the internal screening screen 45, allows the recycled plastic granule material to be effectively screened through the mesh of the screening screen 45. A soft strap handle 42 is installed on the front end screw of the U-shaped frame 43, which makes it easy for personnel to hold the soft strap handle 42 to drive the U-shaped frame 43 for installation and removal. The U-shaped frame 43 is fixedly installed on the recycled plastic granule collection box 4 by assembly bolts 44. When the assembly bolts 44 are loosened, the U-shaped frame 43 can be easily installed and removed from the recycled plastic granule collection box 4.

[0042] The screening screen 45 is located above the belt conveyor 3. The recycled plastic granules screened by the screening screen 45 can fall directly onto the belt conveyor 3. In this way, the belt conveyor 3 can transport them to the designated location for collection. The screening length of the screening screen 45 is less than the width of the conveyor belt of the belt conveyor 3. The belt conveyor 3 facilitates the transport of the screened recycled plastic granules through the conveyor belt.
