Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, in particular to an iron removing machine for plastic particles. Background Technique

[0002] Plastic particles are the common name of plastic pellets, which are raw materials for storing, transporting and processing plastic in semi-finished form. During the processing of plastic particles, small metal fragments will be mixed into the granulator. During the granulation process, smaller metal debris will be mixed into the molten material and form in the plastic particles. Therefore, it is necessary to screen and remove iron from the plastic particles.

[0003] After retrieval, the patent with the Chinese patent application number 201821252991.2 discloses an iron removing machine for plastic particles. The key points of its technical solution include a housing and a screening device arranged in the housing. The screening device includes a rotating shaft and a magnetic shaft arranged horizontally in the housing. A driving member for driving the rotating shaft to rotate towards the magnetic shaft is fixedly arranged on the housing. A conveyor belt is covered outside the rotating shaft and the magnetic shaft. A feeding port is opened directly above the conveyor belt at the top of the housing, a waste discharging port is opened directly below the conveyor belt at the bottom of the housing, and a discharging port is opened on one side of the magnetic shaft away from the rotating shaft at the bottom of the housing. The utility model has the effects of filtering iron-containing plastic particles, protecting equipment and improving product quality.

[0004] The above patent uses the structure of a magnetic shaft and a multi-stage conveyor belt to screen and remove iron from plastic particles. However, this structure is not convenient for cleaning the conveyor belt that adsorbs a large amount of metal. After long-term use, a large amount of metal debris adheres to the magnetic shaft, which will cause the magnetic shaft to be unable to normally adsorb metal, gradually reduce the adsorption force on metal debris, and then reduce the quality of iron removal screening. Secondly, there is a situation of plastic particle accumulation during iron removal screening in this patent. Therefore, the plastic particles located in the upper layer will not be adsorbed, which will lead to the failure of screening and poor practicability.

[0005] Therefore, we propose an iron removing machine for plastic particles to solve the above problems. Summary of the Utility Model

[0036] Working principle: During use, the operation of the iron remover of the device is controlled by the control host 110. Plastic particles enter the installation sleeve 130 from the feeding hopper 210. Under the guiding action of the guiding arched plate 220, the plastic particles are evenly divided into two parts and slide to the feeding grooves 230 on both sides. The hydraulic rod 250 drives the partition plate 251 to move up and down to control the opening and closing of the feeding grooves 230, and can control the plastic particles to enter the iron removal mechanism through the feeding grooves 230. The reduction motor 410 drives the driving shaft 420 to rotate, and the rotation of the driving shaft 420 drives the material distributing roller 430 to rotate. The distance between the lowest point of the material distributing roller 430 and the sliding table 320 is slightly larger than the size of the plastic particles. The passing plastic particles are agitated by the material distributing roller 430, which can block a large number of incoming plastic particles and make the plastic particles slide down evenly on the sliding table 320 under the agitation of the material distributing roller 430, so that the plastic particles can slide on the sliding table 320 in a flat state. The magnetic attraction blocks 350 adsorb the metal debris contained in the passing plastic particles. The cooperation of multiple magnetic attraction blocks 350 can perform multi-stage iron removal screening on the plastic particles, and can perform all-round iron removal screening operations on the plastic particles. When it is necessary to clean the magnetic attraction blocks 350, the iron removal mechanism on this side is controlled by the feeding mechanism to stop the entry of plastic particles. The electric telescopic rod 520 drives the installation sliding seat 330 to move down, and then drives the magnetic attraction blocks 350 at the top to move down. At this time, the stepping motor 540 drives the installation shaft 331 in the middle part to rotate. The rotation of the installation shaft 331 directly drives the connecting bracket 340 to flip and drives the pulley 550 to rotate. The pulley 550 drives the pulleys 550 on the adjacent two sides to rotate synchronously through the transmission belt 551, and can drive multiple connecting brackets 340 to flip simultaneously, and then flip the magnetic attraction blocks 350 at the top to the bottom, and the clean magnetic attraction blocks 350 at the bottom are replaced to the top. The electric telescopic rod 520 drives the installation sliding seat 330 to move up. At this time, the iron removal screening operation can be continued. The driving motor 630 drives the lead screw 631 to rotate, the rotation of the lead screw 631 drives the sliding seat 640 to move, the movement of the sliding seat 640 drives the driving plate 650 to move, and the driving plate 650 drives the scraper 660 to move through the connecting column 651. The scraper 660 scrapes the magnetic attraction blocks 350, and can automatically clean the metal debris attached to the magnetic attraction blocks 350. The scraped metal debris is collected and discharged through the discharge groove 670.
