[0002] The recycling and reuse of waste plastics has been widely adopted by modern chemical enterprises. After being manually screened and sorted, waste plastics need to go through processes such as crushing, washing, granulation, and modification to become various transparent and opaque plastic particles. They are then classified according to their appearance and finally become reusable recycled materials. Currently, in the first process of waste plastics, most of the time, manual labor is needed to screen the waste plastics on the conveyor belt and remove large impurities and stones.

[0003] However, existing screening devices cannot absorb and filter the dust generated during the screening process when screening waste plastics, which affects the working environment of the staff and thus affects the applicability of the device.

[0028] Example 1

[0029] like Figure 1-6 As shown, this utility model provides a technical solution: a waste plastic vibrating screen feeding device, including a conveying device 1, a screening box 2 fixedly installed on the upper part of the conveying device 1, a door 4 hinged to the front of the screening box 2, a discharge box 5 fixedly installed on the right side of the screening box 2, and a connecting assembly 3 installed on the upper part of the conveying device 1. The connecting assembly 3 includes a dust removal mechanism 31 installed on the upper part of the conveying device 1. A screening mechanism 32 is provided on the upper part of the conveying device 1. The dust removal mechanism 31 includes a processing pipe 311 connected to the left side of the conveying device 1. A guardrail 312 is fixedly installed at the inner end of the processing pipe 311. An installation groove is opened inside the processing pipe 311, and an installation frame 313 is inserted into the installation groove. A filter plate 314 is fixedly installed inside the installation frame 313. The upper part of the mounting frame 313 has a slot 315. A fan 316 is fixedly installed on the outside of the processing pipe 311 via a base. The upper part of the processing pipe 311 has a first sliding groove 317. A first sliding rod 318 is fixedly connected to the inner wall of the first sliding groove 317. A first slider 319 is slidably connected to the outer wall of the first sliding rod 318. A first spring 3110 is fixedly connected to the inner wall of the first sliding groove 317. A limit rod 3111 is fixedly connected to the upper part of the first slider 319. A locking rod 3112 is movably connected to one end of the limit rod 3111. A pull rod is fixedly connected to the top of the locking rod 3112. A second spring 3113 is fixedly connected to the upper part of the limit rod 3111. A sealing ring is fixedly connected to the inner wall of the processing pipe 311, and the sealing ring is set in the gap between the mounting groove and the mounting frame 313.

[0030] In this embodiment, one end of the first spring 3110 is fixedly connected to the first slider 319, the bottom of the limiting rod 3111 is fitted to the upper part of the mounting frame 313, the snap-fit ​​rod 3112 is snap-fitted to the slot 315, and the top of the second spring 3113 is fixedly connected to the pull rod. Through the cooperation of the processing pipe 311, guardrail 312, mounting frame 313, filter plate 314, slot 315, fan 316, first slide groove 317, first slide rod 318, first slider 319, first spring 3110, limiting rod 3111, snap-fit ​​rod 3112, and second spring 3113, the dust generated during the screening of waste plastics can be absorbed and filtered, thereby improving the working environment for workers. The mounting frame 313 is easy to disassemble manually, which facilitates manual cleaning of the filter plate 314 and facilitates subsequent use.

[0031] Furthermore, the input end of the fan 316 is connected to the processing pipe 311 via a connecting pipe.

[0032] When in use, the device uses a fan 316 to expel air from the processing pipe 311, which then absorbs the dust generated during the waste plastic screening process. The dust is filtered by the filter plate 314, improving the working environment for staff. Furthermore, when the mounting frame 313 needs to be disassembled, simply pull the lever upwards to separate the locking rod 3112 from the locking slot 315. When the locking rod 3112 engages with the locking slot 315, the first spring... When the spring 3110 is in a stretched state, the first slider 319 can slide in the first groove 317 through the first slide rod 318 under the action of the elastic force of the first spring 3110. This allows the limiting rod 3111, which is fixedly connected to the upper part of the first slider 319, to stay in a position away from the upper part of the mounting frame 313, freeing up the operator's hand. Then, the mounting frame 313 can be pulled out manually, which facilitates the manual cleaning of the filter plate 314 and prevents the filter holes of the filter plate 314 from becoming clogged, thus affecting subsequent use.

[0033] Example 2

[0034] Based on Embodiment 1, a preferred embodiment of the waste plastic vibrating screen feeding device provided by this utility model is as follows: Figures 1 to 6As shown: The screening mechanism 32 includes a second slide groove 321 formed on the inner wall of the screening box 2. A second slide rod 322 is fixedly connected to the inner wall of the second slide groove 321. A second slider 323 is slidably connected to the outer wall of the second slide rod 322. A third spring 324 is fixedly connected to the inner wall of the second slide groove 321. A screening frame 325 is fixedly installed on the outer side of the second slider 323. A vibration motor 326 is installed on the upper part of the screening frame 325. A through hole 327 is formed on the right side of the screening box 2. A limiting groove 328 is formed on the inner wall of the through hole 327. A fixing rod 329 is fixedly connected to the inner wall of the limiting groove 328. A connecting block 3210 is slidably connected to the outer wall of the fixing rod 329.

[0035] In this embodiment, one end of the third spring 324 is fixedly connected to the second slider 323, and the third spring 324 is sleeved on the outside of the second slide rod 322. Through the cooperation of the second slide groove 321, the second slide rod 322, the second slider 323, the third spring 324, the screening frame 325, the vibration motor 326, the through hole 327, the limiting groove 328, the fixing rod 329, and the connecting block 3210, the waste plastic can be screened, thereby removing impurities such as sand and soil, which facilitates the subsequent production and processing of waste plastic.

[0036] Furthermore, there are two connecting blocks 3210, which are symmetrically distributed in the screening box 2, and the connecting blocks 3210 are fixedly connected to the screening box 325.

[0037] When in use, the waste plastic is manually added from the feed hopper at the top of the screening box 2. The waste plastic then falls onto the upper part of the screening frame 325. Under the action of the vibrating motor 326 and the limiting action of the second slide bar 322, the second slider 323, and the third spring 324, the screening frame 325 vibrates, thereby vibrating and screening the waste plastic. This removes impurities such as sand and mud, facilitating subsequent processing of the waste plastic. The limiting action of the fixed rod 329 and the connecting block 3210 makes the screening frame 325 more stable during vibration. The screened waste plastic falls to the right into the discharge box 5, and then onto the upper part of the conveying device 1 for conveying.
