Technical Field

[0001] The utility model relates to the technical field of plastic bottle flakes cleaning, in particular to a plastic bottle flakes impurity removing device. Background Art

[0002] Plastic bottle flakes usually refer to sheet-like plastic objects formed by crushing recycled plastic bottles. Since recycled plastic bottles are usually used, the plastic bottle flakes formed after crushing usually contain debris such as label paper. Therefore, before further processing of the plastic bottle flakes, it is often necessary to remove the impurities from the plastic bottle flakes to ensure the quality of the products processed from the plastic bottle flakes as much as possible.

[0003] In the process of using the plastic bottle flakes impurity removing device to remove impurities from the plastic bottle flakes, the label paper is separated from the plastic bottle flakes under the action of wind mainly based on the difference in weight between the plastic bottle flakes and the label paper mixed therein. This method of removing impurities from the plastic bottle flakes, after the plastic bottle flakes are put into the feed pipe, only relies on the wind force of the fan to absorb the plastic bottle flakes, which often leads to low efficiency in sucking the plastic bottle flakes.

[0036] like Figure 2 and Figure 5-Figure 7 As shown, the mounting device 5 includes two control plates 53, the surfaces of the first air separation tube 32 and the second air separation tube 35 are provided with sliding grooves, the two control plates 53 are respectively slidably connected to the surfaces of the sliding grooves on the first air separation tube 32 and the second air separation tube 35, and the other ends of the two control plates 53 are fixedly connected to the fixing frame 54.

[0038] Working principle: When using the plastic bottle flakes impurity removal device to remove impurities from plastic bottle flakes, first connect the plastic bottle flakes impurity removal device to an external power source, then start the first fan 31, the second fan 34 and the third fan 36 of the impurity removal mechanism 3, then put the plastic bottle flakes into the feed pipe 2, under the wind force of the first fan 31, the plastic bottle flakes enter the first air separation cylinder 32, at this time, the plastic bottle flakes fall into the first return selection tube 33, and the impurities selected by the air are discharged through the discharge port 38 of the first air separation cylinder 32, and at the same time Under the action of the wind force of the second fan 34, the plastic bottle flakes enter the second air separation cylinder 35 through the first re-selection pipe 33, and the plastic bottle flakes fall into the second re-selection pipe 39. At this time, the impurities selected by the secondary air are discharged through the discharge port 38 of the second air separation cylinder 35. The plastic bottle flakes in the second re-selection pipe 39 enter the discharge cylinder 37 under the action of the wind force of the third fan 36, and are discharged through the discharge cylinder 37, thus completing the impurity removal work for the plastic bottle flakes. The entire plastic bottle flake impurity removal device can be stably placed on the ground through the mounting frame 1. When the plastic bottle flakes are being removed, the driving motor 401 is started to drive the rotating rod 403 to rotate on the inner wall of the feeding pipe 2. At the same time, the rotation of the rotating rod 403 drives the rotating roller 404 and the nylon strip 405 to rotate inside the feeding pipe 2. The rotation of the nylon strip 405 drives the plastic bottle flakes in the feeding pipe 2 to separate and approach the first fan 31. When the nylon strip 405 passes through the slide plate 406, the scraper block 407 can scrape the nylon strip 405 to avoid the plastic bottle flakes sticking to the surface of the nylon strip 405 as much as possible. At the same time, the rotation of the nylon strip 405 causes the slide plate 406 to drive the slider 408 to slide on the surface of the fixed rod 409, so that the nylon strip 405 and the spring drive the slider 408 to slide on the surface of the fixed rod 409. Under the action of the elastic force 410, the slider 408 can reciprocate on the surface of the fixed rod 409, thereby having a buffering effect, avoiding major damage to the nylon strip 405 as much as possible, and ensuring the service life of the nylon strip 405 as much as possible. The driving motor 401 can be installed on the feeding pipe 2 through the mounting plate 402. By setting up the bulk material device 4, when the plastic bottle flakes are subjected to impurity removal treatment, the separation of the plastic bottle flakes can be promoted as much as possible, and the impurity removal effect on the plastic bottle flakes can be avoided as much as possible due to the adhesion of debris to the plastic bottle flakes. At the same time, the plastic bottle flakes can be driven close to the first fan 31, thereby improving the feeding efficiency of the plastic bottle flakes as much as possible.

[0039] When it is necessary to install the collecting bag at the discharge port 38, the control screw 58 is rotated to drive the control screw 58 to rotate on the inner wall of the first fixed plate 51 and the surface of the second fixed plate 52, so that the control plate 53 drives the fixed frame 54 to move away from the discharge port 38, and then the collecting bag is moved close to the fixed block 56, and the fixed screw 57 is rotated to make it close to the collecting bag to fix the collecting bag, and then the control screw 58 is rotated to drive the fixed frame 54 close to the discharge port 38, so that the circular protrusion 55 is stuck in the discharge port 38 to complete the installation of the collecting bag. By setting the installation device 5, when it is necessary to install the collecting bag at the discharge port 38, the staff can avoid going to a higher position, thereby facilitating the installation of the collecting bag and ensuring the safety of the staff as much as possible.
