Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, and in particular to a plastic particle conveying and feeding device with an impurity separation structure. Background Technology

[0002] During the production process, plastic granules may become inconsistent in shape and size due to wear and tear on cutting tools and molds. At the same time, raw materials often contain dust and impurities. If these impurities are not separated, they will affect the purity of the plastic granules, thereby reducing the quality of plastic products. For example, during injection molding, this may lead to product defects and reduced strength. Traditional plastic granule conveying and feeding equipment, without an effective impurity separation structure, may cause impurities to clog the conveying pipes, affecting conveying efficiency and even requiring frequent shutdowns for cleaning, thus reducing the continuity and efficiency of production.

[0003] Early impurity separation mechanisms relied on manual sieving and visual selection by workers, which could only remove large particles of impurities and could not handle small impurities. In addition, manual labor was prone to fatigue, the accuracy of sieving decreased over time, and labor costs were high. However, current impurity separation devices mostly use vibrating screens to remove impurities. Although this has replaced manual labor and the removal effect is better, the vibration causes light impurities on the surface of the material to enter the next process with the material, which in turn leads to a decrease in product quality and a reduction in processing efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a plastic granule conveying and feeding device with an impurity separation structure, aiming to improve the problem of the inability to efficiently remove impurities in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a plastic granule conveying and feeding device with an impurity separation structure, comprising a buffer box, a connecting pipe fixedly connected to the inner wall of the buffer box, an air inlet pipe fixedly connected to the inner wall of the connecting pipe, a square fan fixedly connected to the inner wall of the air inlet pipe, a filter screen fixedly connected to the inner wall of the air inlet pipe, a separation chamber fixedly connected to the outer wall of the connecting pipe, a support plate fixedly connected to the outer wall of the separation chamber, an air pump fixedly connected to the top of the support plate, an air outlet pipe fixedly connected to the inner wall of the separation chamber, a cloth bag fixedly connected to the outer wall of the air outlet pipe, and a metering structure fixedly connected to the outer wall of the buffer box, the function of which is to restrict the feeding and prevent blockage.

[0006] As a further description of the above technical solution: The quantitative structure includes a control shell, the inner wall of which is fixedly connected to the outer wall of the buffer box. A motor shell is fixedly connected to the outer wall of the control shell. A motor is fixedly connected to the inner wall of the motor shell. A transmission shaft is fixedly connected to the output end of the motor. Multiple driving periodic gears are fixedly connected to the outer wall of the transmission shaft. A driven periodic gear is meshed with the outer wall of the driving periodic gear. A rotating shaft is fixedly connected to the inner wall of the driven periodic gear. A torsion spring is fixedly connected to the outer wall of the rotating shaft. A rack is meshed with the outer wall of the driven periodic gear. A clamping plate is fixedly connected to the outer wall of the rack.

[0007] As a further description of the above technical solution: The outer wall of the separation chamber is fixedly connected to a connection channel, and the outer wall of the connection channel is fixedly connected to a temporary storage box.

[0008] As a further description of the above technical solution: The inner wall of the temporary storage box is fixedly connected to a lifting shell, and the outer wall of the lifting shell is fixedly connected to a support frame.

[0009] As a further description of the above technical solution: The inner wall of the lifting shell is fixedly connected to a discharge port, and the outer wall of the lifting shell is fixedly connected to a gear shell.

[0010] As a further description of the above technical solution: The inner wall of the gear housing is fixedly connected to a second motor, and the output end of the second motor is fixedly connected to a drive spur gear.

[0011] As a further description of the above technical solution: The outer wall of the driving spur gear is meshed with a driven spur gear, the inner wall of the driven spur gear is fixedly connected with a worm, and the outer wall of the worm is rotatably connected with a sealing plate.

[0012] As a further description of the above technical solution: A screen is fixedly connected to the inner wall of the separation chamber, an impurity box is slidably connected to the inner wall of the separation chamber, and a handle is fixedly connected to the outer wall of the impurity box.

[0013] This utility model has the following beneficial effects: In this invention, after the machine is started, the material enters from the top of the control housing and then enters the buffer tank. The square fans on both sides are activated, which generates an airflow in the connecting pipe, causing the material to rush into the separation chamber at a certain speed. The material on both sides collides with each other, causing light impurities on the surface of the material to scatter. The air pump is activated, which generates an airflow that rushes into the cloth bag through the air outlet pipe, thereby creating a negative pressure in the air outlet pipe, which causes the light impurities to enter the cloth bag and be collected. The uncollected material is then screened by a screen to remove heavy impurities, thus completing the impurity removal process and achieving the purpose of efficient separation, thereby improving product quality and processing efficiency. In this invention, after the material is placed above the control housing, the motor is started, which drives the transmission shaft to rotate, thereby causing the active periodic gear to rotate. When the teeth on the surface of the active periodic gear and the teeth on the surface of the rotating shaft engage, the driven periodic gear rotates, causing the rack to move, which in turn causes the clamping plate to move, and the torsion spring to contract. When the teeth of the active periodic gear disengage from the driven periodic gear, the torsion spring causes the rotating shaft to return to its original position, which in turn causes the clamping plate to return to its original position, thus achieving the purpose of quantitative measurement. This method is highly efficient and low in cost. Attached Figure Description

[0021] Working principle: After the machine is started, the material enters from the top of the control housing 201 and then enters the buffer box 1.
