Description

Technical Field

[0001] This utility model belongs to the field of waste plastic film recycling technology, specifically relating to a waste plastic film impurity separator. Background Technology

[0002] Greenhouse film is a type of plastic film material used to cover agricultural greenhouses. When it ages and becomes unusable after being exposed to sun and rain, recycling and reuse can not only benefit the environment but also generate significant economic value. However, greenhouse plastic film is usually used outdoors, and its edges are covered with soil. Therefore, during the recycling process, in addition to the dust and dirt attached to its surface, the film also carries a lot of soil and stones, and these impurities are difficult to separate once mixed with the film.

[0003] Chinese patent document CN221021920U discloses a waste plastic film recycling and processing device. The device feeds the recycled plastic film into the main body of the device through the feeding port, and at the same time starts the servo motor, blower, vacuum cleaner and unidirectional motor to crush, air classify and screen the falling plastic film, thereby reducing the soil residue in the plastic film and reducing the impact of dust generated by crushing and screening on the human body.

[0004] However, in existing technologies, recycling and processing devices can generally separate lighter impurities such as floating ash and soil particles from plastic films, while heavier impurities such as soil clumps and stones are difficult to separate effectively. In addition, the device capacity is limited, and when there are a lot of plastic films to be processed, they can often only be processed in batches. Therefore, a waste plastic film impurity separator is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a waste plastic film impurity separator.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A waste plastic film impurity separator includes a separation component that can continuously separate different impurities with different mass and volume from the plastic film. A feeding component is provided on one side of the separation component that can cut the plastic film fed into the separator. A crushing component is provided inside the separation component that can divide the plastic film and impurities during the movement of the plastic film.

[0008] The separation assembly includes a guide that can laterally convey the plastic film falling from the feeding assembly after rotation, a screening component that can effectively separate different impurities carried by the plastic film, a collection component that can prevent the screened impurities from scattering disorderly, and a drive component that can control the operation of the guide.

[0009] The material guide includes a support, a rotating drum is movably installed between the supports, and a spiral guide plate is fixedly connected to the inner side of the rotating drum;

[0010] The screening component includes a first frame fixedly installed on the outer side of the rotating drum, a first filter plate fixedly installed inside the first frame, and a second frame provided on one side of the first frame, with a second filter plate fixedly installed inside the second frame.

[0011] The crushing assembly includes a ring frame fixedly connected to the support on the side away from the rotating drum, with ribs fixedly connected between the ring frames, and ribs fixedly connected to the outer side of the ribs.

[0012] Preferably, the guide component also includes a toothed ring fixedly connected to the outer side of the rotating drum, and two sealing rings are provided on one side of the toothed ring.

[0013] Preferably, the collection component includes a cross frame fixedly connected above the support, a dust collection hood is provided between the two sealing rings and the cross frame, a baffle is provided on one side of the dust collection hood, a vacuum cleaner is fixedly installed above the cross frame, and a vacuum pipe is fixedly connected between the dust collection hood and the air inlet of the vacuum cleaner.

[0016] Preferably, the second frame is located on the side of the first frame away from the feeding component, and both the first filter plate and the second filter plate are integrally formed with filter holes, and the diameter of the filter holes of the first filter plate is larger than that of the filter holes of the second filter plate.

[0017] Preferably, the sealing ring is rotatably connected to the dust collection hood.

[0018] Preferably, the gear ring meshes with the gear.

[0019] The beneficial effects of this utility model are as follows: the screening element set on the outer side of the rotating drum and the spiral guide plate inside the rotating drum enable the rotating drum, which rotates under the action of the driving element, to continuously drive the segmented plastic film falling from the feeding component to rotate and move laterally. Combined with the setting of the collecting element and the crushing component, different types of impurities contained in the plastic film can leave the rotating drum one after another when they move to the positions of the first filter plate and the second filter plate, so that this separator can continuously process plastic film while ensuring the impurity removal effect.

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] like Figures 1-7 As shown, a waste plastic film impurity separator includes a separation component 1 that can continuously separate different impurities with different mass and volume from the plastic film. A feeding component 2 is provided on one side of the separation component 1 to cut the plastic film fed into the separator. A crushing component 3 is provided inside the separation component 1 to divide the plastic film and impurities during the movement of the plastic film.

[0034] In this embodiment: the separation component 1 includes a guide that can laterally convey the plastic film falling from the feeding component 2 after rotation, a screening component that can effectively separate different impurities carried by the plastic film, a collection component that can prevent the screened impurities from scattering disorderly, and a drive component that can control the operation of the guide.

[0035] The material guiding component includes a support 101, a rotating drum 102 movably mounted between the supports 101, and a spiral guide plate 105 fixedly connected to the inner side of the rotating drum 102. The screening component includes a first frame 106 fixedly mounted on the outer side of the rotating drum 102, a first filter plate 107 fixedly mounted inside the first frame 106, a second frame 108 provided on one side of the first frame 106, and a second filter plate 109 fixedly mounted inside the second frame 108. The material guiding component also includes a toothed ring 103 fixedly connected to the outer side of the rotating drum 102. Two sealing rings 104 are provided on the side. The collection component includes a cross frame 110 fixedly connected to the support 101. A dust collection hood 111 is provided between the two sealing rings 104 and the cross frame 110. A baffle 112 is provided on one side of the dust collection hood 111. A vacuum cleaner 113 is fixedly installed on the top of the cross frame 110. A suction pipe 114 is fixedly connected between the dust collection hood 111 and the air inlet of the vacuum cleaner 113. The driving component includes a motor 115 fixedly installed below the cross frame 110. A gear 116 is fixedly connected to the output end of the motor 115.

[0036] The support 101 is rotatably connected to the rotating drum 102. The second frame 108 is located on the side of the first frame 106 away from the feeding assembly 2. The first filter plate 107 and the second filter plate 109 are both integrally formed with filter holes, and the diameter of the filter holes of the first filter plate 107 is larger than that of the filter holes of the second filter plate 109. The sealing ring 104 is rotatably connected to the dust collection hood 111. The gear ring 103 is meshed with the gear 116.

[0037] The support 101 restricts the movable range of the rotating drum 102, allowing it to rotate under external force. The rotating drum 102 provides mounting positions for components such as the spiral guide plate 105, the first frame 106, and the second frame 108. The rotation of the output end of the motor 115 is transmitted to the rotating drum 102 through the gear 116 and the gear ring 103, enabling the rotating drum 102 to rotate relative to the support 101 after the motor 115 starts running. The sealing ring 104 improves the sealing effect between the rotatable rotating drum 102 and the stationary dust collection cover 111. The spiral guide plate 105, which rotates with the rotating drum 102, allows the plastic film to move horizontally. The first filter plate 107 and the second filter plate 109 are installed at different positions on the rotating drum 102 by the first frame 106 and the second frame 108, respectively. The first filter plate 107 and the second filter plate 109 allow the impurities carried by the plastic film to leave the rotating drum 102 at different positions. The crossbar 110 provides installation positions for components such as the dust hood 111, the baffle 112, and the vacuum cleaner 113. After the vacuum cleaner 113 is running, it can continuously suck the air inside the dust hood 111 surrounding the outer side of the rotating drum 102 through the suction pipe 114, so that a negative pressure can be formed inside the dust hood 111.

[0038] In this embodiment: the feeding assembly 2 includes a feeding hopper 201 fixedly connected to one of the supports 101 on the side away from the rotating drum 102. Support rods 202 are fixedly connected to the front and rear of the feeding hopper 201. A carrier frame 203 is fixedly connected to one end of the support rod 202. A cylinder 204 is fixedly installed on the carrier frame 203. A knife holder 205 is fixedly connected to the telescopic end of the cylinder 204. A cutter 206 is fixedly connected to the knife holder 205.

[0039] The support rod 202 is slidably connected to the knife holder 205; the plastic film that needs to be separated from impurities is guided to the rotary drum 102 through the open feed hopper 201; the carrier 203 mounted by the support rod 202 provides the mounting position for the cylinder 204, so that the cylinder 204 can drive the knife holder 205 to slide relative to the support rod 202. After the position of the knife holder 205 is changed, it can adjust the depth of the cutter 206 entering the feed hopper 201. After contacting the plastic film, the cutter 206 can cut it by its own movement.

[0040] In this embodiment: the crushing component 3 includes a ring frame 301 fixedly connected to the side of the support 101 away from the rotating drum 102, and a rib 302 fixedly connected between the ring frames 301. A rib cutter 303 is fixedly connected to the outer side of the rib 302.

[0041] The prism rod 302 is installed through the rotating cylinder 102 via the ring frame 301. The prism rod 302 provides an installation position for the prism blade 303, which cuts the plastic film and soil clumps it comes into contact with.

[0042] Working principle: When this separator is installed and used for the separation of impurities in the recycling of waste plastic film, the vacuum cleaner 113 and motor 115 are running, and the cylinder 204 is running intermittently. The plastic film to be processed is put into the feed hopper 201. Under the action of the cylinder 204, the cutter 206 will intermittently enter the feed hopper 201 to a certain depth and then return to its original position. During this process, the plastic film will be cut into segments. After the cut plastic film falls into the continuously rotating drum 102, it will rotate and be laterally conveyed by the spiral guide plate 105.

[0043] As the plastic film moves within the rotating drum 102, most of the stones and soil it contains will fall into the lower part of the drum 102, while a small portion will be flung away by centrifugal force. As the drum 102 rotates, these impurities will pass through the filter holes of the first filter plate 107 and leave the drum 102. They will then either collide with the baffle 112 or fall directly below the drum 102. In addition, due to the setting of the crushing component 3, the plastic film will be divided by contact with the blade 303 as it moves. Similarly, the soil adhering to the plastic film will be crushed or cut and then leave the rotating drum 102 from the first filter plate 107, thus completing the separation of heavier soil clumps, stones, and other impurities.

[0044] As the plastic film continues to move within the rotating drum 102, the vacuum hood 111, which is under negative pressure inside, will continuously draw out lighter impurities such as floating dust and soil particles contained in the plastic film through the filter holes on the second filter plate 109. These impurities will fall into the vacuum hood 111 or be sucked into its interior by the vacuum cleaner 113.

[0045] After the above two stages of impurity removal, the plastic film will leave the separator from the end of the rotating drum 102 away from the feeding assembly 2 as it continues to move.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
