Description

Technical Field

[0001] This utility model relates to the field of plastic recycling, and in particular to a plastic recycling metal impurity screening machine. Background Technology

[0002] Plastic is a common material with good plasticity, which can be processed into items of different shapes for people to use. During processing, the raw materials need to be pre-treated. In the pre-treatment process, the materials need to be screened to remove excess substances and materials that do not meet the size requirements.

[0003] In the existing technology, when screening recycled plastic granules, metal impurities may remain inside the plastic. Therefore, after screening, a secondary screening is required to remove the remaining metal impurities, which is time-consuming. To address this issue, a plastic recycling metal impurity screening machine is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a plastic recycling metal impurity screening machine, including a support plate 1 for supporting the entire device. A screening cylinder 2 for screening plastic particles is installed at the top of the support plate 1. Plastic particles that meet the requirements fall out from the bottom of the screening cylinder 2, while oversized plastic particles fall out from the opening at the right end of the screening cylinder 2. A collection mechanism 3 for collecting plastic particles of the required size is provided at the top of the support plate 1 near the bottom of the screening cylinder 2. The collection mechanism 3 includes a fixing frame 31 for supporting the entire collection mechanism 3. The bottom end of the fixing frame 31 is fixedly connected to the top of the support plate 1. The top of the fixed frame 31 is provided with a shielding component 35 for shielding the top opening of the fixed frame 31. An electromagnetic plate 33 for attracting metal particles is fixedly connected to the inner wall of the fixed frame 31. A scraping component 34 for cleaning the electromagnetic plate 33 is provided at the left end of the fixed frame 31. The scraping component 34 includes a push plate 343 for pushing the metal particles. The push plate 343 is slidably connected to the right end of the fixed frame 31. The electromagnetic plate 33 can be cleaned by pushing the metal particles at the top of the electromagnetic plate 33 using the push plate 343. A threaded rod 344 for moving the push plate 343 is threadedly connected to the right end of the push plate 343.

[0032] Reference Figure 2 - Figure 4The scraping assembly 34 also includes a fixing plate 341 for supporting the motor 342. The left end of the fixing plate 341 is fixedly connected to the right end of the fixing bracket 31. The top of the fixing plate 341 is equipped with a motor 342 for driving the threaded rod 344 to rotate. The motor 342 is prior art and has forward and reverse rotation capabilities. It can start working as soon as the power is turned on. Since it is prior art and can be implemented by those skilled in the art, it will not be described in detail here. The right end of the threaded rod 344 is fixedly connected to the left end of the output shaft of the motor 342. The threaded rod 344 can be driven to rotate by starting the motor 342. The left end of the push plate 343 is fixedly connected to... There is a protrusion 345 for pushing the baffle 351. The front end of the fixing frame 31 is fixedly connected to a collection box 32 for collecting plastic particles. The rear end of the collection box 32 is provided with an opening. The rear end opening of the collection box 32 is connected to the front end of the electromagnetic plate 33. The plastic particles sliding down the surface of the electromagnetic plate 33 can fall directly into the interior of the collection box 32, thus realizing the collection of qualified products. The shielding component 35 includes a collection box 355 for collecting metal particles. The collection box 355 is inserted into the rear end of the fixing frame 31. By removing the collection box 355 from the interior of the fixing frame 31, the metal particles inside can be cleaned.

[0033] Reference Figure 3 - Figure 5 The top of the fixing frame 31 is slidably connected to a baffle 351 for closing the top opening of the fixing frame 31. The left end of the baffle 351 is fixedly connected to a sliding frame 352 for moving and resetting the baffle 351. The rear end of the fixing frame 31 is fixedly connected to a storage box 353 for guiding the sliding frame 352 to slide horizontally. The sliding frame 352 passes through and is slidably connected to the left end of the storage box 353. By using the storage box 353 to guide the sliding frame 352, it can be made to slide stably. The right end of the sliding frame 352 is fixedly connected to a useful... A reset spring 354 is used to move and reset the sliding frame 352. The right end of the reset spring 354 is fixedly connected to the inner wall of the storage box 353. The reset spring 354 will pull the sliding frame 352 to the right at all times. A handle for the operator to move the second collection box 355 is fixedly connected to the rear end of the second collection box 355. The handle is set to L-shape. During production and use, the electromagnetic plate 33 and the fixed frame 31 can be fitted with a clearance. In this way, a vibration motor can be set at the bottom of the electromagnetic plate 33 to vibrate the electromagnetic plate 33 to assist in screening.

[0034] Working principle: During screening, plastic granules are poured into the screening cylinder 2 from the top. Plastic granules that meet the size requirements will fall out from the bottom of the screening cylinder 2, while oversized plastic granules will fall out from the opening at the right end of the screening cylinder 2. The plastic granules falling from the bottom of the screening cylinder 2 will fall into the collection mechanism 3 under the action of gravity. When the plastic granules pass the top of the electromagnetic plate 33, due to the action of the electromagnetic plate 33, the plastic granules can fall normally along the inclined surface of the electromagnetic plate 33, while the metal granules will be attracted to the top of the electromagnetic plate 33, thus achieving the separation of plastic granules and metal granules.

[0035] When the electromagnetic plate 33 needs to be cleaned, the motor 342 can be started to drive the threaded rod 344 to rotate, which will drive the push plate 343 to move to the left. The push plate 343 moving to the left will drive the metal particles at the top of the electromagnetic plate 33 to move to the left. At the same time, the push plate 343 will press the baffle 351 through the protrusion 345 to move it to the left. In this way, the top openings of the fixing frame 31 and the second collection box 355 will be exposed. As the push plate 343 continues to move, the metal particles will be pushed into the interior of the second collection box 355, thus achieving the collection of metal particles. When the top of the electromagnetic plate 33 is cleaned, the motor 342 can be started to drive the push plate 343 to move and reset. At the same time, the reset spring 354 will also pull the sliding frame 352 to drive the baffle 351 to move and reset, re-closing the top of the second collection box 355 and the fixing frame 31.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
