Description

Technical Field

[0001] This utility model relates to the field of plastic processing equipment technology, and in particular to a plastic granule impurity removal device for plastic processing. Background Technology

[0002] Plastic processing refers to the process of shaping various plastic raw materials into products with desired shapes and properties through heating and pressurization. It is widely used in packaging, electronics, automotive, construction, and many other industrial fields. In plastic processing, plastic granules serve as the basic raw material, and their purity directly affects the quality and performance of the final product. Because plastic granules are prone to contamination with impurities such as metal shavings, sand, and dust during production, transportation, and storage, if these impurities are not effectively removed, they may not only damage equipment during subsequent melt molding but also cause defects such as bubbles and cracks in the finished product, severely affecting its appearance and mechanical properties.

[0003] An existing plastic granule impurity removal device (such as the one disclosed in utility model patent CN 221834750 U) includes a box, a fan, a collection box, a suction pipe, a suction hood, a fixed plate, a first motor, a threaded rod, a moving block, a connecting rod, a fixed block, and other movable components. It can comprehensively remove impurities from plastic granules through a combination of wind-driven adsorption and mechanical vibration, improving the impurity removal effect and collection capacity, thereby enhancing the quality of plastic products and the practicality of the device. However, in actual use, this device still has significant shortcomings: the removed plastic granules are usually collected through a single collection frame. Since the proportion of plastic granules in the material discharged from the impurity removal box is relatively large, and the collection frame has a limited capacity, operators need to frequently replace the collection frame. During replacement, granules at the discharge port easily fall to the ground due to the replacement interval, causing material waste, increasing the risk of secondary pollution, and reducing the continuity and automation level of the overall production line.

[0004] Therefore, to address the shortcomings of existing technologies, we urgently need a plastic pellet impurity removal device for plastic processing. This device should be able to achieve efficient impurity removal while possessing multi-channel automatic switching discharge functionality, avoiding material leakage when changing collection containers, significantly improving the continuity and safety of impurity removal operations, better meeting the demands of modern plastic processing for high efficiency, high cleanliness, and automated production, and providing strong support for the sustainable development of the plastic processing industry. Utility Model Content

[0005] The purpose of this invention is to provide a plastic granule impurity removal device for plastic processing. This device solves the problem in existing technologies where the removed plastic granules are typically collected using a single collection frame. Because the material discharged from the impurity removal box contains a large proportion of plastic granules, and the collection frame has limited capacity, operators need to frequently replace the collection frame. During replacement, granules at the discharge port easily fall to the ground due to the gaps between replacements, causing material waste, increasing the risk of secondary pollution, and reducing the continuity and automation level of the overall production line.

[0006] To achieve the above objectives, this utility model provides a plastic granule impurity removal device for plastic processing, comprising an impurity removal box and a support frame connected to the bottom of the impurity removal box;

[0007] A support platform is provided on one side of the discharge port of the impurity removal box. Two bearing plates are slidably connected to the top of the support platform, and a collection frame is provided on the top of each of the two bearing plates.

[0008] The support platform has a movable groove that runs through the top of the support platform. Both ends of the support platform are equipped with a push structure that connects to the collection frame. One side of the support platform is connected to the support frame through two connecting plates.

[0009] The movable groove has sliding grooves on both sides that penetrate the side wall of the support platform, and the bearing plate has sliding plates that are adapted to the sliding grooves fixedly connected to both sides.

[0010] Each of the two support plates has a placement slot on its top, and the two placement slots are connected to each other on the side closest to each other.

[0011] The movable groove has guide rods connected to both sides inside, and the bearing plate slides with the two guide rods.

[0012] One end of the connecting plate is fixedly connected to a connecting sleeve that is bolted to the support frame, and the other end is fixedly connected to a positioning plate that is bolted to the side wall of the support platform.

[0013] The pushing structure includes a pushing cylinder installed at the end of the support platform, and the output end of the pushing cylinder is connected to the side wall of the adjacent bearing plate.

[0014] This utility model discloses a plastic granule impurity removal device for plastic processing. By setting two slidingly connected support plates and corresponding collection frames, combined with a push structure, it realizes a multi-channel automatic switching discharge function. It effectively solves the problems of material leakage, waste, and secondary pollution caused by the limited capacity of traditional single collection frames and the need for frequent replacement. It greatly improves the continuity and automation level of impurity removal operations. At the same time, the sliding support plate structure combined with the moving groove design makes the collection frame switching process fast and accurate, without the need for machine downtime, thus improving production efficiency.

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1

[0024] Please see Figure 1-5 As shown, a plastic granule impurity removal device for plastic processing in this embodiment includes an impurity removal box 3 and a support frame 4 connected to the bottom of the impurity removal box 3;

[0025] A support platform 1 is provided on one side of the discharge port of the impurity removal box 3. Two bearing plates 6 are slidably connected to the top of the support platform 1, and a collection frame 2 is provided on the top of each of the two bearing plates 6.

[0026] The support platform 1 has a movable groove that runs through the top of the support platform 1. Both ends of the support platform 1 are equipped with a push structure that connects to the collection frame 2. One side of the support platform 1 is connected to the support frame 4 through two connecting plates 8.

[0027] During the impurity removal operation, the plastic granules to be processed enter the impurity removal box 3 from the top. After impurity removal processes such as wind adsorption and vibrating screening, the clean plastic granules are discharged from the bottom outlet of the impurity removal box 3 and fall into the collection frame 2 on the support platform 1 below. The support platform 1 has two slidably connected bearing plates 6, each bearing plate 6 is equipped with a collection frame 2, which can be used alternately to receive materials. When one collection frame 2 is full, the pushing structure set at both ends of the support platform 1 is activated. The pushing structure drives the bearing plate 6 to slide along the moving groove opened at the top of the support platform 1, so that the other empty collection frame 2 is accurately aligned with the outlet of the impurity removal box 3 to continue receiving materials. At the same time, the full collection frame 2 is moved out of the discharge area for easy replacement or cleaning by the operator. Throughout the process, the support platform 1 is stably connected to the support frame 4 at the bottom of the impurity removal box 3 through two connecting plates 8, ensuring that the equipment operates smoothly and reliably.

[0028] Example 2

[0029] Please see Figure 1-5 As shown in this embodiment, a plastic granule impurity removal device for plastic processing has sliding grooves 7 penetrating the side walls of the support platform 1 on both sides of the moving groove. Sliding plates 9 adapted to the sliding grooves 7 are fixedly connected to both sides of the bearing plate 6. Specifically, by setting the sliding grooves 7 and sliding plates 9, sliding grooves 7 penetrating the side walls of the support platform 1 are opened on both sides of the moving groove, and sliding plates 9 adapted to the sliding grooves 7 are fixedly connected to both sides of the bearing plate 6. This design not only ensures the stability and accuracy of the bearing plate 6 when sliding on the support platform 1, but also reduces frictional resistance, allowing the bearing plate 6 to perform switching operations more smoothly, thus improving the reliability and efficiency of the equipment operation.

[0030] Guide rods 11 are connected to both sides of the inside of the moving trough. The bearing plate 6 slides with the two guide rods 11. Specifically, by setting the guide rods 11, guide rods 11 are connected to both sides inside the moving trough, so that the bearing plate 6 slides with the two guide rods 11. This design further enhances the directional guidance and stability of the bearing plate 6 when sliding, ensuring that the bearing plate 6 always maintains linear movement during the switching process, preventing deviation or jamming, and ensuring the normal operation of the equipment.

[0031] The pushing structure includes a pushing cylinder 5 installed at the end of the support platform 1. The output end of the pushing cylinder 5 is connected to the side wall of the adjacent support plate 6. Specifically, by using the pushing cylinder 5, the pushing structure is designed to include a pushing cylinder 5 installed at the end of the support platform 1, and its output end is directly connected to the side wall of the adjacent support plate 6. This design utilizes the power of the pushing cylinder 5 to quickly and accurately drive the support plate 6 to slide along the sliding groove 7, realizing the automatic switching function of the collection frame 2 and significantly improving work efficiency. At the same time, the automated control method reduces the frequency of manual intervention and improves the safety and cleanliness of the production line.

[0032] Example 3

[0033] Please see Figure 1-5 As shown in this embodiment, a plastic granule impurity removal device for plastic processing has a placement groove 10 on the top of each of the two support plates 6. The two placement grooves 10 are connected to each other on their adjacent sides. Specifically, through the design of the placement grooves 10, placement grooves 10 are opened on the top of each of the two support plates 6, and the two placement grooves 10 are connected to each other on their adjacent sides. This structure facilitates the installation and disassembly of the collection frame 2, and ensures that when one collection frame 2 is full, the other collection frame 2 can be seamlessly connected to the discharge port of the impurity removal box 3, avoiding material leakage and improving the continuity and stability of the collection process.

[0034] One end of the connecting plate 8 is fixedly connected to a connecting sleeve 13 that is bolted to the support frame 4, and the other end is fixedly connected to a positioning plate 12 that is bolted to the side wall of the support platform 1. Specifically, through the setting of the connecting sleeve 13 and the positioning plate 12, the connecting plate 8 is fixedly connected to one end of the connecting sleeve 13 that is bolted to the support frame 4, and the other end is fixedly connected to the positioning plate 12 that is bolted to the side wall of the support platform 1. This design strengthens the connection strength and stability between the support platform 1 and the support frame 4, ensuring that the entire device will not be displaced or loosened due to vibration during operation, providing a more stable working platform and extending the service life of the equipment.

[0035] This solution includes the following work process:

[0036] During the impurity removal process, the plastic granules to be processed enter the impurity removal box 3 from the top. After undergoing impurity removal processes such as wind adsorption and vibrating screening, the clean plastic granules are discharged from the bottom outlet of the impurity removal box 3 and fall into the collection frame 2 on the support platform 1 below. Two bearing plates 6 are slidably connected to the top of the support platform 1, each bearing plate 6 having a collection frame 2, which can be used alternately to receive materials. When one of the collection frames 2 is full, the pushing structure is activated. The pushing structure consists of a pushing cylinder 5 installed at the end of the support platform 1, whose output end is connected to the side wall of the adjacent bearing plate 6. The pushing cylinder 5 drives the bearing plate 6 to slide along the moving groove opened at the top of the support platform 1. The two sides of the bearing plate 6 are fixedly connected to the sliding groove 7 via sliding plates 9, achieving stable guidance during movement. Simultaneously, the bearing plate 6 also... The guide rods 11 on both sides inside the moving trough slide together to further ensure the straightness and stability of the sliding process. After sliding into place, another empty collection frame 2 is accurately aligned with the discharge port of the impurity removal box 3 to continue receiving materials, while the full collection frame 2 is moved out of the discharge area for easy replacement or cleaning by the operator. The top of both bearing plates 6 is provided with placement slots 10, and the two placement slots 10 are connected to each other on the side closest to each other, which facilitates the quick loading and unloading of the collection frame 2. Throughout the process, the support platform 1 is stably connected to the support frame 4 at the bottom of the impurity removal box 3 through two connecting plates 8. One end of the connecting plate 8 is bolted to the support frame 4 through the connecting sleeve 13, and the other end is bolted to the side wall of the support platform 1 through the positioning plate 12, thereby enhancing the stability and vibration resistance of the overall structure and ensuring the safe and reliable operation of the equipment.

[0037] The detailed benefits of this device are as follows: By setting up two slidingly connected support plates 6 and corresponding collection frames 2, combined with the push cylinder 5 and sliding guide structure, a multi-channel automatic switching discharge function is realized. This effectively solves the problems of material leakage, waste, and secondary pollution caused by the limited capacity of traditional single collection frames and the need for frequent replacement, significantly improving the continuity and automation level of the impurity removal operation. The design of the sliding groove 7 and the sliding plate 9 not only enhances the guidance and stability of the support plate 6 during sliding but also reduces frictional resistance, making the switching of the support plate smoother and more efficient. The addition of the guide rod 11 further improves the straightness of the movement of the support plate 6, preventing deviation or jamming, and ensuring the device's operation. The design of the placement slot 10 facilitates the installation and disassembly of the collection frame 2, and the two placement slots 10 are interconnected, allowing the collection frame 2 to seamlessly connect to the discharge port of the impurity removal box 3 during switching, preventing material from falling and improving the continuity and sealing of the collection process; the combined structure of the connecting plate 8, connecting sleeve 13 and positioning plate 12 strengthens the connection between the support platform 1 and the support frame 4, ensuring that the entire device will not be displaced or loosened due to vibration during operation, extending the service life of the equipment; in addition, the introduction of the push cylinder 5 realizes the automatic switching of the collection frame 2, significantly improving work efficiency, reducing the frequency of manual intervention, and improving the safety and cleanliness of the production line.
