Description

Technical Field

[0001] This invention belongs to the field of waste film recycling and regeneration technology, and particularly relates to a waste film recycling and regeneration device and method. Background Technology

[0002] The recycling and reuse of waste film is a crucial link in resource recycling, especially in the production of biodegradable PO film (polyolefin film), where high levels of cleanliness and material continuity are required. Currently, waste film recycling processes typically involve two main steps: crushing and washing. In existing technologies, the crushed film fragments are mostly processed using batch washing equipment, such as fixed washing tanks with agitation mechanisms. These devices are often simple in structure and have limited functionality; they require shutdown for loading and unloading during the washing process, making continuous production impossible and severely limiting processing efficiency and system automation.

[0003] Furthermore, existing cleaning devices often suffer from insufficient agitation, low cleaning fluid exchange efficiency, and poor dehydration during the cleaning process, resulting in incomplete cleaning of film fragments or excessively high moisture content, which affects the quality of subsequent regeneration granulation and film forming. In particular, the lack of effective sealing and workstation isolation mechanisms during the transition between cleaning and dehydration can easily lead to cross-contamination or cleaning fluid splashing, further reducing the cleanliness and production efficiency of the recycled film.

[0004] Therefore, there is an urgent need for a waste film recycling and regeneration device and method that can achieve continuous feeding, washing, dewatering and unloading in one integrated manner, and has efficient stirring and dewatering functions, so as to improve the quality of recycled film and the overall efficiency of the regeneration production line.

[0008] A further technical solution includes a fixed sleeve fixed on the inner wall of the cleaning tank and four rotating components. The fixed sleeve and the rotating seat are coaxially arranged. Each rotating component includes a gear one fixed on one end of the work station cylinder near the rotating seat. An external gear ring is rotatably connected to the side wall of the fixed sleeve. The external gear ring meshes with the gear one. An internal gear ring is embedded in the inner wall of the external gear ring. A motor two is fixed on the side wall of the cleaning tank. A gear two is fixed on the rotating end of the motor two. The gear two meshes with the internal gear ring.

[0009] A further technical solution includes a rotating ring rotatably connected to the side wall of the work station cylinder, the rotating ring being connected to an arc-shaped sealing plate, a fixed shaft being fixedly provided on the side wall of the rotating ring, two blocks being provided on the inner wall of the cleaning tank away from the rotating seat, and an elastic component for elastically pushing the arc-shaped sealing plate being provided on the work station cylinder.

[0010] In a further technical solution, the elastic component includes a second compression spring connected to the side wall of the arc-shaped sealing plate. The end of the second compression spring is fixed to the side wall of the work station cylinder. An arc-shaped support rod is fixed to the side wall of the work station cylinder, and the second compression spring is sleeved on the arc-shaped support rod.

[0011] A further technical solution is provided in which a guide shaft is fixed on the side wall of the cleaning tank, the stop block is slidably connected to the guide shaft, one end of the stop block extends into the cleaning tank, the other end of the stop block is connected to a compression spring, the end of the compression spring is fixed on the guide shaft, the compression spring is sleeved on the guide shaft, and the end of the stop block extending into the cleaning tank is provided with a first inclined surface and a second inclined surface.

[0012] In a further technical solution, the transmission assembly includes three inclined elongated holes evenly arranged on the rotating ring, and a transmission shaft fixed on the side wall of the stirring plate, wherein the transmission shaft is slidably connected within the inclined elongated holes.

[0013] A further technical solution is provided, in which two rotating rings are rotatably connected to the side wall of the work station cylinder, the two rotating rings are fixedly connected by a connecting plate, and three inclined elongated holes are evenly arranged on each of the two rotating rings. A drive shaft is fixed on both sides of the stirring plate, and the drive shafts on both sides of the stirring plate are slidably connected in the inclined elongated holes of the two rotating rings respectively.

[0014] A method for recycling and regenerating waste film, based on the aforementioned waste film recycling and regeneration device, includes the following steps:

[0015] S1. The rotating seat drives the four station cylinders to rotate, and one of the station cylinders moves to a position below one end of the belt conveyor.

[0016] S2. The rotating mechanism drives the station cylinder to rotate until the notch on the station cylinder rotates upward. The opening and closing mechanism drives the arc-shaped sealing plate to move, and the arc-shaped sealing plate opens the notch.

[0017] S3. The belt conveyor transports the broken old film through the gap into the work station cylinder, and the arc-shaped sealing plate then closes the gap.

[0018] S4. The rotating seat drives the four station cylinders to rotate, so that the station cylinder containing the broken old film is immersed in the cleaning solution in the cleaning tank. The cleaning solution enters the station cylinder through the filter screen. The station cylinder drives the three stirring plates and the broken old film to rotate. The three stirring plates stir the cleaning solution and the broken old film, and clean the broken old film.

[0019] S5. After the old film is cleaned, the rotating seat drives the four station cylinders to rotate. The station cylinder containing the old film is separated from the cleaning solution. As the station cylinder rotates, the old film inside the station cylinder is spun dry.

[0020] S6. After the shredded old film is spun dry, the rotating seat drives the four station cylinders to rotate, so that the station cylinder containing the shredded old film is above the belt conveyor. The rotating mechanism drives the station cylinder to rotate until the notch on the station cylinder rotates upward. The opening and closing mechanism drives the arc-shaped sealing plate to move, and the arc-shaped sealing plate opens the notch. The cleaned old film in the station cylinder falls onto the belt conveyor and is conveyed and discharged.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] This invention provides a waste film recycling device and method. A rotating base drives four station cylinders in a cyclic revolution. Combined with the rotation, opening and closing, and stirring actions at each station, it achieves continuous and automated feeding, washing, dewatering, and unloading of crushed waste film, effectively overcoming the problems of intermittent operation, low efficiency, and poor washing effect in existing technologies. Specific beneficial effects include:

[0023] 1. Continuous production is achieved: By setting up four workstations for cyclic operation, the feeding, washing, dewatering and unloading processes are carried out simultaneously at different workstations. Each process does not interfere with the others, and the entire recycling process can be completed without stopping the machine, which significantly improves production efficiency.

[0024] 2. Improved cleaning effect and quality: The work station cylinder is equipped with a radially sliding stirring plate, which can effectively disperse and agitate the membrane fragments during the cleaning process, prevent them from agglomerating, promote the exchange of cleaning fluid, and ensure that the membrane fragments are thoroughly cleaned; at the same time, the filter screen design allows impurities to be discharged smoothly, improving the cleanliness of the regenerated membrane.

[0025] 3. Excellent dehydration effect, avoiding secondary pollution: Utilizing the principle of centrifugal dehydration, the water in the washed film fragments is effectively removed through high-speed rotation; the baffles, arc-shaped partitions and arc-shaped parts constitute a closed dehydration environment, preventing water splashing or cross-contamination, ensuring a clean working environment, and facilitating subsequent processing;

[0026] 4. Reasonable structure and high degree of automation: Through the coordinated action of the rotating mechanism, opening and closing mechanism, elastic components and transmission components, the automatic control of actions such as opening and closing of the notch and extension and retraction of the stirring plate is realized, reducing manual intervention, ensuring stable and reliable operation, and reducing the intensity of operation and production costs.

[0027] 5. Wide range of applications and strong practicality: This device and method are particularly suitable for the recycling and cleaning of waste biodegradable PO film and other plastic films.

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0044] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0045] like Figures 1-8 As shown, an embodiment of the present invention provides a waste film recycling and regeneration device and method, including a cleaning tank 101, and further including: a rotating seat 102 rotatably connected to the inner wall of the cleaning tank 101, and a motor 103 fixed to the side wall of the cleaning tank 101, the rotating end of the motor 103 being connected to one end of the rotating seat 102; four station cylinders 104 are evenly rotatably connected to the other end of the rotating seat 102; a rotating mechanism 2 is provided on the cleaning tank 101, the rotating mechanism 2 being used to drive the station cylinders 104 to rotate; a filter screen 105 is fixed to the side wall of the station cylinder 104, a notch 106 is also provided on the side wall of the station cylinder 104, an arc-shaped sealing plate 107 is slidably connected to the side wall of the station cylinder 104 along an arc-shaped trajectory, and an opening and closing mechanism 3 is provided on the cleaning tank 101, the opening and closing mechanism 3 being connected to the station cylinders 104 via a public... The rotation and self-rotation drive the arc-shaped sealing plate 107 to close or open the notch 106; three stirring plates 108 are radially slidably connected to the side wall of the work station cylinder 104, and a transmission assembly 5 is provided on the work station cylinder 104. The transmission assembly 5 drives the stirring plates 108 to slide radially by moving the arc-shaped sealing plate 107; a belt conveyor 109 and a belt conveyor 110 are installed on the cleaning tank 101. The belt conveyor 110 is located between the four work station cylinders 104. Four baffles 111 are evenly fixed at the other end of the rotating seat 102. An arc-shaped partition 112 is fixed inside the cleaning tank 101. The belt conveyor 110 is installed inside the arc-shaped partition 112. The four baffles 111 and one arc-shaped partition 112 separate the four work station cylinders 104. An arc-shaped part 113 is provided on one side of the cleaning tank 101.

[0046] In this embodiment of the invention, the four parts of the rotating seat 102—upper, lower, left, and right—are respectively a material unloading station, a cleaning station, a material feeding station, and a dewatering station. Motor 103 drives the rotating seat 102 to rotate, causing the four station cylinders 104 to revolve around the axis of the rotating seat 102, thus switching the four station cylinders 104 between stations until one station cylinder 104 moves to the left-hand feeding station. The rotating mechanism 2 then drives the station cylinder 104 to rotate clockwise. The closing mechanism 3 drives the arc-shaped sealing plate 107 to open the notch 106 by rotating the station cylinder 104 clockwise. At this time, the notch 106 of the station cylinder 104 faces upward. The belt conveyor 109 feeds the crushed waste film into the station cylinder 104 through the notch 106. Then, the rotating mechanism 2 drives the station cylinder 104 to rotate counterclockwise. The opening and closing mechanism 3 drives the arc-shaped sealing plate 107 to close the notch 106 by rotating the station cylinder 104 counterclockwise, thus completing the feeding.

[0047] The rotating seat 102 continues to rotate and drives the station cylinder 104 to the cleaning station. The station cylinder 104 is immersed in the cleaning solution, which enters the station cylinder 104 through the filter screen 105. Due to its own weight, the crushed waste film is located at the top of the station cylinder 104. As the station cylinder 104 rotates, it drives the three stirring plates 108 to rotate. At this time, the stirring plates 108 drive the waste film at the top of the station cylinder 104 to move downwards until the stirring plates 108 rotate to an upward tilt. The waste film moves upwards due to its own weight, thus avoiding the waste film from being unable to be thoroughly cleaned due to aggregation. It can also promote the flow of waste film and cleaning solution, improving the cleaning effect of waste film. Impurities in the waste film flow out of the station cylinder 104 through the filter screen 105, completing the cleaning.

[0048] The rotating seat 102 continues to rotate and drives the station cylinder 104 to move to the dewatering station. The rotating mechanism 2 drives the station cylinder 104 to rotate. The waste film after cleaning in the station cylinder 104 is centrifuged and dewatered. Through the design of the baffle 111, the arc-shaped baffle 112 and the arc-shaped part 113, the washing liquid thrown out during centrifugal dewatering is prevented from entering the adjacent station cylinder 104 or being thrown out of the washing tank 101, thereby achieving separation treatment.

[0049] The rotating seat 102 continues to rotate and drives the station cylinder 104 to move to the unloading station. The rotating mechanism 2 drives the station cylinder 104 to rotate clockwise. The opening and closing mechanism 3 drives the arc-shaped sealing plate 107 to open the notch 106 through the clockwise rotation of the station cylinder 104. At this time, the notch 106 of the station cylinder 104 faces downward. The transmission component 5 drives the stirring plate 108 to slide radially through the movement of the arc-shaped sealing plate 107. The stirring plate 108 disengages from the interior of the station cylinder 104, making the interior of the station cylinder 104 smooth and facilitating the unloading of the station cylinder 104. 04. Unloading: The cleaned waste film in station cylinder 104 falls onto belt conveyor 110 and is conveyed and discharged. At this time, the adjacent baffles 111 form a V-shaped guide plate, which facilitates the unloading of the cleaned waste film in station cylinder 104 onto belt conveyor 110, thus completing the unloading process. By setting four station cylinders 104, this invention can realize continuous feeding, cleaning, dewatering and unloading, and each process does not affect the others, realizing continuous feeding, cleaning, dewatering and unloading steps, and improving the efficiency of waste film recycling.

[0050] like Figure 2 , Figure 5 and Figure 9 As shown, in a preferred embodiment of the present invention, the rotating mechanism 2 includes a fixed sleeve 201 fixed on the inner wall of the cleaning tank 101, and four rotating components. The fixed sleeve 201 is coaxially arranged with the rotating seat 102. The rotating components include a gear 202 fixed on one end of the work station cylinder 104 near the rotating seat 102. An external gear ring 203 is rotatably connected to the side wall of the fixed sleeve 201. The external gear ring 203 meshes with the gear 202. An internal gear ring 206 is embedded in the inner wall of the external gear ring 203. A motor 204 is fixed on the side wall of the cleaning tank 101. A gear 205 is fixed on the rotating end of the motor 204. The gear 205 meshes with the internal gear ring 206.

[0051] In this embodiment of the invention, the outer gear rings 203 of the four rotating components are linearly arranged on the fixed sleeve 201. The second motor 204 drives the second gear 205 to rotate, the second gear 205 drives the inner gear ring 206 to rotate, the inner gear ring 206 drives the outer gear ring 203 to rotate, the outer gear ring 203 drives the first gear 202 to rotate, and the first gear 202 drives the station cylinder 104 to rotate. The four rotating components are matched one-to-one.

[0052] like Figure 1 , Figure 4 , Figure 6 and Figure 8As shown, in a preferred embodiment of the present invention, the opening and closing mechanism 3 includes a rotating ring 301 rotatably connected to the side wall of the work station cylinder 104. The rotating ring 301 is connected to the arc-shaped sealing plate 107. A fixed shaft 304 is fixedly provided on the side wall of the rotating ring 301. Two stops 303 are provided on the inner wall of the cleaning tank 101 away from the rotating seat 102. An elastic component 4 for elastically pushing the arc-shaped sealing plate 107 is provided on the work station cylinder 104. The elastic component 4 includes a second compression spring 401 connected to the side wall of the arc-shaped sealing plate 107. The end of the second compression spring 401 is fixedly provided on the side wall of the work station cylinder 104. An arc-shaped support rod 402 is fixedly provided on the side wall of the work station cylinder 104. The second compression spring 401 is sleeved on the arc-shaped support rod 402.

[0053] In this embodiment of the invention, in the initial state, the second compression spring 401 pushes the arc-shaped sealing plate 107, which moves and blocks the notch 106. When the station cylinder 104 moves to the unloading station, the station cylinder 104 rotates clockwise, which drives the rotating ring 301 and the fixed shaft 304 to revolve clockwise around the axis of the station cylinder 104 until the fixed shaft 304 contacts the stop block 303. The stop block 303 prevents the fixed shaft 304 from continuing to revolve clockwise around the axis of the station cylinder 104. The fixed shaft 304, the rotating ring 301 and the arc-shaped sealing plate 107 stop rotating. The station cylinder 104 continues to rotate clockwise, and the second compression spring 401 is compressed until the notch 106 of the station cylinder 104 opens. At this time, the notch 106 faces downward, the station cylinder 104 reverses, and the second compression spring 401 can push the arc-shaped sealing plate 107 to reseal the notch 106.

[0054] The work station cylinder 104 moves to the feeding station and rotates clockwise. The work station cylinder 104 drives the rotating ring 301 and the fixed shaft 304 to revolve clockwise around the axis of the work station cylinder 104 until the fixed shaft 304 contacts the stop block 303. The stop block 303 prevents the fixed shaft 304 from continuing to revolve clockwise around the axis of the work station cylinder 104. The fixed shaft 304, the rotating ring 301 and the arc-shaped sealing plate 107 stop rotating. The work station cylinder 104 continues to rotate clockwise until the notch 106 of the work station cylinder 104 opens. At this time, the notch 106 faces upward. The work station cylinder 104 reverses, and the compression spring 401 can push the arc-shaped sealing plate 107 to reseal the notch 106.

[0055] like Figure 1 , Figure 4 , Figure 6 , Figure 8 and Figure 10As shown, in a preferred embodiment of the present invention, a guide shaft 305 is fixedly provided on the side wall of the cleaning tank 101, and a stop block 303 is slidably connected to the guide shaft 305. One end of the stop block 303 extends into the cleaning tank 101, and the other end of the stop block 303 is connected to a compression spring 306. The end of the compression spring 306 is fixed on the guide shaft 305, and the compression spring 306 is sleeved on the guide shaft 305. The end of the stop block 303 extending into the cleaning tank 101 is provided with a first inclined surface 307 and a second inclined surface 308.

[0056] In this embodiment of the invention, to prevent the rotating seat 102 from driving the work station cylinder 104, the rotating ring 301, and the fixed shaft 304 to rotate counterclockwise around the axis of the rotating seat 102 (e.g. Figure 3 As shown), the stop 303 obstructs the counterclockwise rotation of the fixed shaft 304. The stop 303 adopts an elastic telescopic design, which is achieved in the following way:

[0057] In the initial state, the compression spring 306 pushes the stop block 303. Under the guidance of the guide shaft 305, the stop block 303 extends into the cleaning tank 101. The rotating seat 102 drives the station cylinder 104, the rotating ring 301, and the fixed shaft 304 to rotate counterclockwise around the axis of the rotating seat 102 (e.g., Figure 3 As shown), when the station cylinder 104 rotates to the unloading station on the upper part of the rotating seat 102 (as shown) Figure 3 and Figure 4 As shown), if the fixed shaft 304 contacts the stop block 303, the fixed shaft 304 pushes the stop block 303 through the inclined plane 2 308. The stop block 303 overcomes the elastic force of the compression spring 1 306 and disengages from the cleaning box 101, thus allowing the fixed shaft 304 to revolve counterclockwise around the axis of the rotating seat 102. When the notch 106 needs to be opened, the station cylinder 104 rotates clockwise. The station cylinder 104 drives the rotating ring 301 and the fixed shaft 304 to revolve clockwise around the axis of the station cylinder 104 until the fixed shaft 304 contacts the side of the stop block 303 away from the inclined plane 2 308. The stop block 303 prevents the fixed shaft 304 from continuing to revolve clockwise around the axis of the station cylinder 104 until the notch 106 of the station cylinder 104 opens and faces downward.

[0058] When the work station cylinder 104 rotates to the feeding station on the left side of the rotary seat 102 (e.g.) Figure 3 and Figure 4As shown), if the fixed shaft 304 contacts the stop block 303, the fixed shaft 304 pushes the stop block 303 through the inclined plane 307. The stop block 303 overcomes the elastic force of the compression spring 306 and disengages from the cleaning box 101, thus allowing the fixed shaft 304 to revolve counterclockwise around the axis of the rotating seat 102. When the notch 106 needs to be opened, the station cylinder 104 rotates clockwise. The station cylinder 104 drives the rotating ring 301 and the fixed shaft 304 to revolve clockwise around the axis of the station cylinder 104 until the fixed shaft 304 contacts the side of the stop block 303 away from the inclined plane 308. The stop block 303 prevents the fixed shaft 304 from continuing to revolve clockwise around the axis of the station cylinder 104 until the notch 106 of the station cylinder 104 opens and faces upward.

[0059] The telescopic design of the stop block 303 prevents the rotary seat 102 from causing the work station cylinder 104, the rotating ring 301, and the fixed shaft 304 to rotate counterclockwise around the axis of the rotary seat 102 (e.g., Figure 3 As shown, when the work station cylinder 104 switches work stations, the stop block 303 obstructs the movement of the fixed shaft 304 before the work station cylinder 104 reaches the designated work station, thus preventing the notch 106 from being opened prematurely.

[0060] like Figure 4 , Figure 6 and Figure 8 As shown, in a preferred embodiment of the present invention, the transmission assembly 5 includes three inclined elongated holes 501 evenly arranged on the rotating ring 301, and a transmission shaft 502 fixed on the side wall of the stirring plate 108. The transmission shaft 502 is slidably connected in the inclined elongated holes 501. Two rotating rings 301 are rotatably connected to the side wall of the work station cylinder 104. The two rotating rings 301 are fixedly connected by a connecting plate 302. The two rotating rings 301 have three inclined elongated holes 501 evenly arranged on each of them. The transmission shafts 502 are fixed on both sides of the stirring plate 108. The transmission shafts 502 on both sides of the stirring plate 108 are slidably connected in the inclined elongated holes 501 of the two rotating rings 301 respectively.

[0061] In this embodiment of the invention, when the rotating ring 301 rotates, it pushes the transmission shaft 502 through the inclined elongated hole 501. The transmission shaft 502 drives the stirring plate 108 to slide radially on the work station cylinder 104. When the stirring plate 108 moves toward the axis of the work station cylinder 104, it enters the work station cylinder 104. After the work station cylinder 104 is immersed in the cleaning solution, the broken waste film, due to its own weight, is located at the top of the work station cylinder 104. As the work station cylinder 104 rotates, it drives the three stirring plates 108 to rotate. At this time, the stirring plate 108 drives the waste film at the top of the station cylinder 104 to move downwards until the stirring plate 108 rotates to tilt upwards. The waste film moves upwards by its own weight, thereby avoiding the waste film from being unable to be thoroughly cleaned due to accumulation. It can also promote the flow of waste film and cleaning liquid, and improve the cleaning effect of waste film. Impurities in the waste film flow out of the station cylinder 104 through the filter screen 105. When unloading, the stirring plate 108 detaches from the inside of the station cylinder 104, making the inside of the station cylinder 104 smooth, which facilitates the unloading of material from the station cylinder 104.

[0062] A method for recycling and regenerating waste film, based on the aforementioned waste film recycling and regeneration device, includes the following steps:

[0063] S1. The rotating seat 102 drives the four station cylinders 104 to rotate, and one of the station cylinders 104 moves to the lower end of the belt conveyor 109.

[0064] S2. The rotating mechanism 2 drives the station cylinder 104 to rotate until the notch 106 on the station cylinder 104 rotates upward. The opening and closing mechanism 3 drives the arc-shaped sealing plate 107 to move, and the arc-shaped sealing plate 107 opens the notch 106.

[0065] S3, the belt conveyor 109 transports the broken old film through the notch 106 into the work station cylinder 104, and the arc-shaped sealing plate 107 then closes the notch 106.
