Description

Technical Field

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

[0002] Currently, the processing of plastic granules often results in a small amount of residual metal debris. Many companies choose not to treat these small amounts of metal debris or simply use magnetic attraction to remove them. This simple magnetic attraction method makes it impossible to completely remove the small amount of metal debris from the accumulated plastic granules, thus affecting the quality of the plastic granule products.

[0003] The prior art CN217169293U provides a device for removing impurities containing ferromagnetic metals from plastic granules. It includes a buffer box with a feed inlet at its top, the feed inlet being trapezoidal in design and narrowing from top to bottom. A discharge outlet is located on the lower side wall of the buffer box, and a first electromagnetic plate is mounted on the side wall of the buffer box near the discharge outlet. A conveyor belt is positioned below the discharge outlet, the position of the conveyor belt corresponding to the position of the first electromagnetic plate. Baffles are mounted on both sides of the conveyor belt. Multiple vibrating motors are evenly distributed within the inner cavity of the conveyor belt, between conveyor rollers. A support plate is mounted at the bottom of each vibrating motor, and the side wall of the support plate is connected to the side wall of the inner cavity of the conveyor belt.

[0004] However, in the existing technology, after a long period of magnetic attraction of magnetic metal, excessive accumulation of metal on the first electromagnetic plate will affect the magnetic attraction efficiency of the magnetic metal in the plastic particles, thus resulting in poor magnetic attraction effect of the magnetic metal. Utility Model Content

[0005] The purpose of this invention is to provide a plastic particle impurity removal device, which aims to solve the technical problem in the prior art that after a long period of magnetic attraction of magnetic metal, excessive accumulation of metal on the first electromagnetic plate will affect the magnetic attraction efficiency of the magnetic metal in the plastic particles, thus resulting in poor magnetic attraction effect of the magnetic metal.

[0006] To achieve the above objectives, this utility model employs a plastic granule impurity removal device, comprising a conveyor belt and an impurity removal mechanism. The impurity removal mechanism includes an impurity removal bracket, a rotary cylinder, a rotary mounting plate, a first electromagnetic plate, a scraper, and an adjusting arm. The impurity removal bracket is fixedly connected to the conveyor belt and located on one side of the conveyor belt. The rotary cylinder is fixedly connected to the impurity removal bracket and located at the lower end of the impurity removal bracket, with the output end of the rotary cylinder passing through the impurity removal bracket and fixedly connected to the rotary mounting plate. The first electromagnetic plate is fixedly connected to the rotary mounting plate and located at the upper end of the rotary mounting plate. The adjusting arm is disposed on one side of the impurity removal bracket, and the scraper is fixedly connected to the adjusting arm and located at one end of the adjusting arm.

[0007] The rotating mounting plate includes an L-plate, an assembly plate, and assembly studs. The assembly plate is fixedly connected to the L-plate and located on one side of the L-plate. There are multiple sets of assembly studs, each set of which is fixedly connected to the assembly plate and located at the upper end of the assembly plate.

[0008] The adjusting arm includes an adjusting bolt, a locking nut, and a scraper block. The adjusting bolt is fixedly connected to the scraper block and is located on one side of the scraper block. The adjusting bolt passes through the impurity removal bracket. The locking nut is threadedly connected to the locking bolt and is sleeved on the outer wall of the adjusting bolt.

[0009] The impurity removal bracket includes an L-shaped frame and a second electromagnetic plate. The second electromagnetic plate is fixedly connected to the L-shaped frame and embedded inside the L-shaped frame. The L-shaped frame has a height adjustment groove and two sets of positioning holes.

[0010] The impurity removal mechanism further includes a multi-stage electric telescopic cylinder and a scraper. The multi-stage electric telescopic cylinder is fixedly connected to the assembly plate and located at the lower end of the assembly plate. The scraper is fixedly connected to the output end of the multi-stage electric telescopic cylinder and located at one end of the multi-stage electric telescopic cylinder.

[0011] This utility model discloses a plastic granule impurity removal device. A conveyor belt is used to transport the plastic granules. An impurity removal bracket is installed on one side of the conveyor belt. The height of an adjusting arm on the impurity removal bracket is adjusted. After determining the height of the adjusting arm, the tilt angle of the scraper is determined. Finally, the adjusting arm is locked to fix the scraper. By adjusting the height and angle of the scraper, the plastic granules on the conveyor belt are scraped and leveled, ensuring they are evenly distributed on the upper part of the conveyor belt. This facilitates subsequent magnetic removal of magnetic metal by an electromagnetic plate. During the removal of magnetic metal impurities, a rotary cylinder controls the rotation of a rotating mounting plate, which simultaneously mounts and secures the first electromagnetic plate. The first electromagnetic plate is positioned at the top of the conveyor belt to remove impurities from the leveled plastic granules. Once a certain amount of magnetic metal is attracted, the conveyor belt stops running. Then, the rotary cylinder rotates the first electromagnetic plate 90°, moving it outside the conveyor belt. The first electromagnetic plate is then de-energized, causing its magnetic force to disappear. The attracted metal impurities then fall off by weight. After cleaning the first electromagnetic plate, it is reset and energized again. The conveyor belt is then restarted, thus achieving the removal of impurities from the plastic granules. This structure effectively cleans the first electromagnetic plate, preventing excessive impurity accumulation from affecting the efficiency of magnetic impurity removal, effectively improving both processing efficiency and impurity removal rate.

Detailed Implementation

[0017] Please see Figures 1 to 3 This utility model provides a plastic granule impurity removal device, including a conveyor belt 101 and an impurity removal mechanism. The impurity removal mechanism includes an impurity removal bracket, a rotary cylinder 102, a rotary mounting plate, a first electromagnetic plate 103, a scraper 104, and an adjusting arm. The impurity removal bracket is fixedly connected to the conveyor belt 101 and located on one side of the conveyor belt 101. The rotary cylinder 102 is fixedly connected to the impurity removal bracket and located at the lower end of the impurity removal bracket. The output end of the rotary cylinder 102 passes through the impurity removal bracket and is fixedly connected to the rotary mounting plate. The first electromagnetic plate 103 is fixedly connected to the rotary mounting plate and located at the upper end of the rotary mounting plate. The adjusting arm is disposed on one side of the impurity removal bracket. The scraper 104 is fixedly connected to the adjusting arm and located at one end of the adjusting arm.

[0018] In this embodiment, the conveyor belt 101 is used to transport plastic granules. The impurity removal bracket is installed on one side of the conveyor belt 101, and the height of the adjusting arm on the impurity removal bracket is adjusted. After determining the height of the adjusting arm, the tilt angle of the scraper 104 is determined, and finally the adjusting arm is locked to fix the scraper 104. By adjusting the height and angle of the scraper 104, the plastic granules on the conveyor belt 101 are scraped and leveled, so that the plastic granules can be evenly spread on the upper end of the conveyor belt 101, which facilitates the subsequent magnetic removal of magnetic metal by the electromagnetic plate. When removing magnetic metal, the rotating cylinder 102 controls the angle of the rotating mounting plate. The system rotates while the rotating mounting plate secures the first electromagnetic plate 103. The first electromagnetic plate 103 is placed at the upper end of the conveyor belt 101 to remove impurities from the leveled plastic granules. When a certain amount of magnetic metal is attracted, the operation of the conveyor belt 101 is stopped. Then, the rotating cylinder 102 rotates 90° to move the first electromagnetic plate 103 to the outside of the conveyor belt 101. The power to the first electromagnetic plate 103 is then cut off, causing its magnetic force to disappear. The attracted metal impurities then fall off by weight. After cleaning the first electromagnetic plate 103, it is reset and powered on. The conveyor belt 101 is then restarted to remove impurities from the plastic granules.

[0019] Furthermore, the rotating mounting plate includes an L-plate 105, an assembly plate 106, and assembly studs 107. The assembly plate 106 is fixedly connected to the L-plate 105 and is located on one side of the L-plate 105. The number of assembly studs 107 is multiple sets, and each set of assembly studs 107 is fixedly connected to the assembly plate 106 and is located at the upper end of the assembly plate 106.

[0020] In this embodiment, the L-plate 105 is connected to the assembly plate 106, and a stepped structure is formed between the L-plate 105 and the assembly plate 106. At the same time, both the L-plate 105 and the assembly plate 106 are made of magnetic shielding material, which can effectively avoid the influence of the first electromagnetic plate 103 on the impurity removal bracket and the rotary cylinder 102. The assembly bolt passes through the first electromagnetic plate 103 and is used with nuts to install and fix the end of the first electromagnetic plate 103.

[0021] Furthermore, the adjusting arm includes an adjusting bolt 108, a locking nut 109, and a scraper block 110. The adjusting bolt 108 is fixedly connected to the scraper block 110 and is located on one side of the scraper block 110. The adjusting bolt 108 passes through the impurity removal bracket. The locking nut 109 is threadedly connected to the locking bolt and is sleeved on the outer wall of the adjusting bolt 108.

[0022] In this embodiment, the scraper block 110 is used to install and fix the scraper plate 104. At the same time, the scraper block 110 is locked by the adjusting bolt 108 and the locking nut 109. The scraper block 110 installs and fixes the scraper plate 104, and locking the scraper block 110 can fix the scraper plate 104.

[0023] Furthermore, the impurity removal bracket includes an L-shaped frame 111 and a second electromagnetic plate 112. The second electromagnetic plate 112 is fixedly connected to the L-shaped frame 111 and is embedded inside the L-shaped frame 111. The L-shaped frame 111 has a height adjustment groove and two sets of positioning holes.

[0024] In this embodiment, the L-frame 111 is the main frame, which is used to fix the rotary cylinder 102 and the rotary mounting plate. At the same time, the L-frame 111 is magnetically fixed to one side of the conveyor belt 101 by the second electromagnetic plate 112. The height adjustment groove is used to adjust the height of the adjustment arm, which can be used for plastic particles of different sizes. The positioning hole is used for positioning when the impurity removal bracket is magnetically installed to avoid angular displacement of the impurity removal bracket during installation.

[0025] Furthermore, the impurity removal mechanism also includes a multi-stage electric telescopic cylinder 113 and a scraper 114. The multi-stage electric telescopic cylinder 113 is fixedly connected to the assembly plate 106 and is located at the lower end of the assembly plate 106. The scraper 114 is fixedly connected to the output end of the multi-stage electric telescopic cylinder 113 and is located at one end of the multi-stage electric telescopic cylinder 113.

[0026] In this embodiment, the multi-stage electric telescopic cylinder 113 is installed at the lower end of the rotating mounting plate, and the scraper 114 is installed at the output end of the multi-stage electric telescopic cylinder 113. When the first electromagnetic plate 103 is de-energized to clean magnetic impurities, the multi-stage electric telescopic cylinder 113 is activated to extend, pushing the scraper 114 to move on the first electromagnetic plate 103 to assist in removing magnetic impurities. This prevents small impurities from remaining adsorbed on the first electromagnetic plate 103 after it has been magnetically attracted, thus assisting in cleaning and improving cleaning efficiency.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
