Description

Technical Field

[0001] This invention belongs to the field of plastic bag recycling and processing technology, specifically a plastic bag recycling and processing device. Background Technology

[0002] Plastic bags, made primarily of plastic, are essential items in daily life, often used to hold other items. They are widely used due to their low cost, light weight, large capacity, and ease of storage. However, if plastic bags are not recycled, they will continue to occupy land resources, causing soil compaction, decreased fertility, and potentially flowing into water bodies with rainwater, threatening the survival of aquatic life. By crushing and recycling them, the spread of "white pollution" can be significantly reduced, and the degree of damage to the ecological environment can be lessened.

[0003] Patent CN222521795U discloses a plastic bag recycling and processing device, which mainly includes a waste crushing chamber body, a waste collection chamber, a separator plate, a waste pressing plate, and a driving mechanism. The driving mechanism consists of two electric push rods, a slider, and a sealing plate. This solution improves collection efficiency by driving the waste pressing plate to move and squeeze the waste through the electric push rods. The placement slot facilitates workers to quickly pick up the waste, improving recycling efficiency. At the same time, the fixing plate is attached to the sealing plate to enhance the stability of the sealing plate. The overall structure is practical and convenient.

[0004] In the above-mentioned solution, after compressing the broken plastic bags into the waste collection bin, the sealing plate on the waste collection bin needs to be opened to remove the compressed waste. Because the compressed waste blocks have a certain degree of elasticity, the squeezing force between the waste blocks and the inner wall of the waste collection bin is very large, making it very difficult for workers to remove the waste blocks from the waste collection bin. Secondly, after removing the waste blocks, they need to be put into recycling bags. Because the waste blocks removed from the waste collection bin are no longer restrained, they are somewhat loose, making it troublesome for workers to put the waste blocks into recycling bags. Therefore, the present invention provides a plastic bag recycling and processing device. Summary of the Invention

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this invention to solve its technical problem is as follows: A plastic bag recycling and processing device of this invention includes a processing base, a funnel fixedly connected to the inlet of the processing base, a crushing mechanism installed on the funnel, a compression mechanism installed inside the processing base, rectangular openings symmetrically opened on both sides of one end of the processing base, each set of rectangular openings being fitted with a C-shaped frame, and a first cylinder fixedly installed on the processing base for driving the C-shaped frame; a discharge nozzle is provided on one side of one set of rectangular openings, with a guide frame placed below one end of the discharge nozzle; a pushing mechanism is provided on one side of the other set of rectangular openings; the compression mechanism includes a sliding plate, which is slidably connected to the processing base. The inner cavity includes a fixed plate fixedly mounted on the slide plate, a movable plate movably mounted on the slide plate, a connecting plate fixedly connected to the movable plate, a hydraulic cylinder fixedly mounted on the processing seat for driving the connecting plate, two sets of slide rods symmetrically arranged inside the movable plate, a fixed block slidably connecting the slide rods, a fixed block fixedly connecting the slide plate, a first spring sleeved on the slide rod, and a pushing mechanism including a pushing column, one end of the pushing column facing another set of rectangular openings, the pushing column slidably mounted on a fixed frame, a threaded sleeve fixedly connected to the pushing column, a screw rod threaded to the threaded sleeve, the screw rod rotatably mounted on the fixed frame, and a first motor fixedly mounted on the fixed frame for the screw rod. The compressed plastic bag fragments are pushed by the pusher column, and the compressed plastic bag fragments automatically separate from the fixed plate and the movable plate, realizing automatic bagging of the compressed plastic bag fragments, reducing manual operation and improving the automation rate of the device. In addition, the channel connecting the discharge nozzle and the area between the fixed plate and the movable plate not only guides the clumps of plastic bag fragments, but also shapes the clumps of plastic bag fragments, preventing them from becoming loose and ensuring that the compressed plastic bag fragments enter the recycling bag in rectangular blocks.

[0007] Preferably, the discharge nozzle is provided with a bagging mechanism, which includes a frame, a processing seat fixedly connected to the frame, four sets of movable frames movably installed in the processing seat, rollers rotatably installed on the movable frames, a second cylinder fixedly installed on the movable frames for driving the movable frames, two sets of first conical wheels installed at both ends of the rollers, multiple sets of first conical wheels closely attached to each other, a second conical wheel closely attached to a set of first conical wheels, a rectangular shaft movably inserted into the second conical wheel, the rectangular shaft rotatably installed on the frame, a connector fixedly connected to the rectangular shaft, a second motor fixedly installed on the frame for driving the connector, four sets of rollers equally distributed around the discharge nozzle, the four sets of rollers respectively facing the four sides of the discharge nozzle, two sets of guide pillars symmetrically installed on the movable frames, the guide pillars movably inserted into the frame, a rectangular hole opened at one end of the second conical wheel, and the rectangular shaft slidably connected to the rectangular hole; The second motor drives the connector and rectangular shaft to rotate together. The rectangular shaft drives the second conical wheel to rotate, which in turn drives the corresponding first conical wheel to rotate. The first conical wheel drives the corresponding roller to rotate. Because the first conical wheels are in close contact with each other, the four sets of rollers rotate simultaneously. The rotating rollers move the recycling bag, so that the recycling bag is quickly and automatically placed on the discharge nozzle. This not only improves the automation rate of the device, but also improves the bagging efficiency of the recycling bag.

[0008] Preferably, the connector includes a driven plate, a driven plate fixedly mounted on one end of a rectangular shaft, a driven plate engaging the driven plate, a driven plate movably mounted on a driven shaft, a second spring sleeved on the driven shaft, a limiting plate slidably connected to the driven shaft, an electric push rod fixedly mounted on a frame for driving the limiting plate, four sets of slots equally spaced on the driven plate, four sets of blocks equally spaced on the driven plate engaging the slots, three sets of rectangular slots equally spaced on the driven shaft, three sets of guide blocks equally spaced in the inner ring of the driven plate, the guide blocks slidably connected to the rectangular slots, one end of the driven shaft rotatably connected to the rectangular shaft, and the other end of the driven shaft connected to a second motor. With the second motor powered on, the drive disc cannot rotate. The slot on the driven disc will press against the block, causing the drive disc to move the guide block along the rectangular groove towards the limit plate. The drive disc also compresses the second spring, and the spring's rebound force acts on the drive disc, damping the rotation of the driven disc. This dampens the rotation of the rollers driven by the recycling bag, causing the rollers to pull the recycling bag in the opposite direction, straightening it. As a result, the recycling bag, along with the pieces of plastic bag fragments, enters and is completely straightened, making full use of the recycling bag.

[0009] The beneficial effects of this invention are as follows: 1. The compressed plastic bag fragments are pushed by the pusher column, and the compressed plastic bag fragments automatically separate from the fixed plate and the movable plate, realizing automatic bagging of the compressed plastic bag fragments, reducing manual operation, improving the automation rate of the device, and the channel connecting the discharge nozzle and the area between the fixed plate and the movable plate not only guides the clumps of plastic bag fragments, but also shapes the clumps of plastic bag fragments, preventing the plastic bag fragments from becoming loose, and ensuring that the compressed plastic bag fragments enter the recycling bag in rectangular blocks.

[0010] 2. When bagging the recycling bag, firstly, the end of the recycling bag is placed over the outlet port, positioning the end of the recycling bag between four sets of rollers. Then, four sets of second cylinders push the corresponding movable frame to move. The movable frame drives the corresponding rollers towards the recycling bag, clamping the recycling bag between the rollers and the side of the outlet. Simultaneously, the first conical wheels at the ends of the rollers are in close contact with each other. During this process, the second conical wheel moves with the movable frame, and the rectangular shaft slides along the rectangular hole on the second conical wheel. Then, the second motor drives the connector to rotate together with the rectangular shaft. The rectangular shaft drives the second conical wheel to rotate, and the second conical wheel drives the corresponding first conical wheel to rotate. The first conical wheel drives the corresponding roller to rotate, and because the first conical wheels are in close contact with each other, all four sets of rollers rotate simultaneously. The rotating rollers move the recycling bag, allowing the recycling bag to be quickly and automatically placed on the outlet. This not only improves the automation rate of the device but also increases the bagging efficiency of the recycling bag. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] Example 1: As Figures 1 to 4As shown in the embodiment of the present invention, a plastic bag recycling and processing device includes a processing base 1. A funnel 2 is fixedly connected to the inlet 12 of the processing base 1. A crushing mechanism 3 is provided on the funnel 2. A compression mechanism 4 is provided inside the processing base 1. Rectangular openings 5 ​​are symmetrically opened on both sides of one end of the processing base 1. A C-shaped frame 6 is inserted into each of the two sets of rectangular openings 5. A first cylinder 7 is fixedly installed on the processing base 1 to drive the C-shaped frame 6. A discharge nozzle 8 is provided on one side of one set of rectangular openings 5. A guide frame 9 is placed below one end of the discharge nozzle 8. A pushing mechanism 10 is provided on one side of the other set of rectangular openings 5. The compression mechanism 4 includes a sliding plate 401, which is slidably connected to the inner cavity of the processing base 1. A fixed plate 402 is fixedly installed on the sliding plate 401, and a movable plate is movably installed on the sliding plate 401. 403, a connecting plate 404 fixedly connected to the movable plate 403, a hydraulic cylinder 405 fixedly installed on the processing seat 1 for driving the connecting plate 404, two sets of slide rods 406 symmetrically arranged in the movable plate 403, a fixing block 407 slidably connected to the slide rods 406, a fixed plate 401 fixedly connected to the fixing block 407, a first spring 408 sleeved on the slide rods 406, a pushing mechanism 10 including a pushing column 102, one end of the pushing column 102 facing another set of rectangular openings 5, the pushing column 102 slidably installed on the fixed frame 101, a screw sleeve 103 fixedly connected to the pushing column 102, a screw 104 screwed to the screw sleeve 103, the screw 104 rotatably installed on the fixed frame 101, and a first motor 105 fixedly installed on the fixed frame 101 for the screw 104.

[0023] Specifically, in the initial state, the area between the fixed plate 402 and the movable plate 403 is located directly below the feed inlet 12. Before processing the plastic bags, the recycling bag is placed on the discharge nozzle 8, and then the plastic bag is placed into the crushing mechanism 3. The crushing mechanism 3 crushes the plastic bags, and the crushed plastic bags fall through the funnel 2 into the area between the fixed plate 402 and the movable plate 403. After the area between the fixed plate 402 and the movable plate 403 is filled with crushed plastic bags, the hydraulic cylinder 405 pushes the connecting plate 404 to move together with the movable plate 403. Then, the movable plate 403 drives the fixed block 407 to move through the first spring 408, and the fixed block 407 drives the slide plate 401 to move. The plastic bag fragments between the fixed plate 402 and the movable plate 403 are moved towards the rectangular opening 5 until the slide plate 401 is blocked and cannot move. At this time, the movable plate 403 continues to move, while the fixed block 407 and the slide plate 401 cannot move. The moving movable plate 403 compresses the first spring 408, and at the same time, the plastic bag fragments located between the fixed plate 402 and the movable plate 403 are compressed by the movable plate 403, thus compressing the plastic bag fragments. When the volume of the plastic bag fragments located between the fixed plate 402 and the movable plate 403 is compressed by half, the compression of the plastic bag fragments is stopped. The first cylinder 7 pushes the C-shaped frame 6 upward, opening the two sets of rectangular openings 5. Then, the first motor 10... 5 drives the screw 104 to rotate. The screw 104, through the screw sleeve 103, drives the pusher column 102 to move towards the opposite rectangular opening 5. The pusher column 102 passes through the rectangular opening 5 and enters between the fixed plate 402 and the movable plate 403. The pusher column 102 pushes the clumps of plastic bag fragments, causing them to enter the discharge nozzle 8 through another set of rectangular openings 5. Guided by the discharge nozzle 8, the clumps of plastic bag fragments are loaded into the recycling bag. As the clumps of plastic bag fragments enter the recycling bag, the recycling bag, along with the clumps of plastic bag fragments, slides along the guide frame 9, achieving automatic bagging of the clumps of plastic bag fragments. After all the clumps of plastic bag fragments are completely inside the recycling bag, the pusher column 102 is retracted. Then, the fixed plate 402 and the movable plate 403 are returned to their initial positions, and the above operation is repeated. Compared with the prior art, the compressed plastic bag fragments are pushed by the pusher column 102, so that the compressed plastic bag fragments are automatically separated from the fixed plate 402 and the movable plate 403, realizing automatic bagging of the compressed plastic bag fragments, reducing manual operation, improving the automation rate of the device, and the channel connecting the discharge nozzle 8 and the area between the fixed plate 402 and the movable plate 403 not only guides the clumps of plastic bag fragments, but also shapes the clumps of plastic bag fragments, preventing the clumps of plastic bag fragments from becoming loose, and ensuring that the compressed plastic bag fragments enter the recycling bag in rectangular blocks.

[0024] like Figures 5 to 7As shown, a bagging mechanism 11 is provided on the discharge nozzle 8. The bagging mechanism 11 includes a frame 111, which is fixedly connected to the processing seat 1. Four sets of movable frames 112 are movably installed in the processing seat 1. Rollers 113 are rotatably installed on the movable frames 112. A second cylinder 114 is fixedly installed on the movable frames 112 for driving the movable frames 112. Two sets of first conical wheels 115 are installed at both ends of the rollers 113. The multiple sets of first conical wheels 115 are in close contact with each other. A second conical wheel 116 is in close contact with one set of first conical wheels 115. The second conical wheel 116 is movably inserted into the first set of first conical wheels 115. A rectangular shaft 117 is rotatably mounted on a frame 111. A connector 118 is fixedly connected to the rectangular shaft 117. A second motor 119 for driving the connector 118 is fixedly mounted on the frame 111. Four sets of rollers 113 are distributed at equal angles around the discharge nozzle 8, with each set of rollers 113 facing one of the four sides of the discharge nozzle 8. Two sets of guide pillars 1121 are symmetrically mounted on the movable frame 112. The guide pillars 1121 are movably inserted into the frame 111. A rectangular hole 1161 is opened at one end of the second conical wheel 116, and the rectangular shaft 117 is slidably connected to the rectangular hole 1161.

[0025] Specifically, the recycling bags are generally quite long. When fitting the recycling bags onto the discharge nozzle 8, the length of the discharge nozzle 8 is limited, so the recycling bags usually need to be manually stacked and fitted onto the discharge nozzle 8 by the staff. This operation method not only reduces the automation rate of the device, but also is slow and reduces the efficiency of bagging the recycling bags. Initially, there is a gap between the four sets of rollers 113 and the four faces of the discharge nozzle 8. The four faces of the discharge nozzle 8 are smooth and straight. Therefore, when bagging the recycling bag, the end of the recycling bag is first placed over the end of the discharge nozzle 8, so that the end of the recycling bag is located between the four sets of rollers 113. Then, the four sets of second cylinders 114 push the corresponding movable frame 112 to move. The movable frame 112 drives the corresponding roller 113 to move towards the recycling bag, so that the recycling bag is clamped between the roller 113 and the side of the discharge nozzle 8. At the same time, the first conical wheels 115 at the ends of the rollers 113 are in close contact with each other. During this process, the second conical wheels 116 move with the movable frame 112, and... The rectangular shaft 117 slides along the rectangular hole 1161 on the second conical wheel 116. Then, the second motor 119 drives the connector 118 to rotate together with the rectangular shaft 117. The rectangular shaft 117 drives the second conical wheel 116 to rotate, and the second conical wheel 116 drives the corresponding first conical wheel 115 to rotate. The first conical wheel 115 drives the corresponding roller 113 to rotate. Because the first conical wheels 115 are in close contact with each other, the four sets of rollers 113 rotate simultaneously. The rotating rollers 113 drive the recycling bag to move, so that the recycling bag is quickly and automatically put on the discharge nozzle 8. This not only improves the automation rate of the device, but also improves the bagging efficiency of the recycling bag.

[0026] Example 2: Figure 8and Figure 9 As shown in the comparative embodiment one, another embodiment of the present invention is as follows: the connector 118 includes a driven disk 1181, which is fixedly mounted on one end of a rectangular shaft 117. A driving disk 1183 engages with the driven disk 1181. The driving disk 1183 is movably mounted on a driving shaft 1182. A second spring 1184 is sleeved on the driving shaft 1182. A limiting plate 1185 is slidably connected to the driving shaft 1182 and fixedly mounted on the frame 111 for driving the limiting plate 118. The electric push rod 1186 of the 5 has four sets of slots 81 at equal angles on the driven plate 1181, and four sets of blocks 83 at equal angles on the driving plate 1183. The blocks 83 engage with the slots 81. The driving shaft 1182 has three sets of rectangular slots 82 at equal angles. The inner ring of the driving plate 1183 has three sets of guide blocks 84 at equal angles. The guide blocks 84 slide to connect with the rectangular slots 82. One end of the driving shaft 1182 is rotatably connected to the rectangular shaft 117, and the other end of the driving shaft 1182 is connected to the second motor 119.

[0027] Specifically, as large pieces of plastic bag fragments enter the recycling bag, the bag will continue to grow longer. Since there is no reverse pulling force, the recycling bag is relatively loose and cannot be fully straightened, so the recycling bag is not fully utilized. Therefore, when bagging the recycling bag, the limiting plate 1185 abuts against the driving disc 1183, compressing the second spring 1184. The second motor 119 drives the driving shaft 1182 to rotate. The driving shaft 1182, through the rectangular groove 82 and the guide block 84, drives the driving disc 1183 to rotate. The driving disc 1183, through the cooperation of the locking block 83 and the locking groove 81, causes the driven disc 1181 to rotate. The driven disc 1181 drives the rectangular shaft 117 to rotate, thus achieving the above-mentioned rapid and automatic bagging of the recycling bag onto the discharge nozzle 8. Before the clumps of plastic bag fragments enter the recycling bag, the electric push rod 1186 pulls the limiting plate 1185, releasing the compression of the second spring 1184 by the limiting plate 1185, and simultaneously moving the limiting plate 1185 away from the driving disc 1183. As the recycling bag lengthens with the clumps of plastic bag fragments entering, the recycling bag will drive the roller 1 When roller 113 rotates, it drives the second conical wheel 116 to rotate via a set of first conical wheels 115. The rotation of the second conical wheel 116 drives the driven disc 1181 to rotate via the rectangular shaft 117. Since the second motor 119 is energized, the driving disc 1183 cannot rotate. The slot 81 on the driven disc 1181 will squeeze the locking block 83, causing the driving disc 1183 to drive the guide block 84 to move along the rectangular groove 82 towards the limiting plate 1185. The driving disc 1183 compresses the second spring 1184. The rebound force of the second spring 1184 acts on the driving disc 1183, generating a damping effect on the rotation of the driven disc 1181. This causes the recycling bag to drive the roller 113 to rotate, generating damping. The roller 113 will pull the recycling bag in the opposite direction, and the recycling bag will be straightened. This allows the recycling bag to be fully utilized as it is completely straightened along with the pieces of plastic bag fragments.

[0028] Working principle: Before processing the plastic bags, the recycling bag set is placed on the discharge nozzle 8, and then the plastic bags are put into the crushing mechanism 3. The crushing mechanism 3 crushes the plastic bags, and the crushed plastic bags fall through the funnel 2 into the area between the fixed plate 402 and the movable plate 403. After the area between the fixed plate 402 and the movable plate 403 is full of crushed plastic bags, the hydraulic cylinder 405 pushes the connecting plate 404 and the movable plate 403 to move together. Then, the movable plate 403 is driven by the first spring 408 to move the fixed plate 402. The fixed block 407 moves, causing the sliding plate 401 to move, which in turn moves the plastic bag fragments between the fixed plate 402 and the movable plate 403 towards the rectangular opening 5, until the sliding plate 401 is blocked and cannot move. At this point, the movable plate 403 continues to move, while the fixed block 407 and the sliding plate 401 cannot move. The moving movable plate 403 compresses the first spring 408, and at the same time, the plastic bag fragments located between the fixed plate 402 and the movable plate 403 are compressed by the movable plate 403, thus compressing the plastic bag fragments. After the volume of the plastic bag fragments between the fixed plate 402 and the movable plate 403 is compressed by half, the compression of the plastic bag fragments is paused. The first cylinder 7 pushes the C-shaped frame 6 upward, opening the two sets of rectangular openings 5. Then, the first motor 105 drives the screw 104 to rotate. The screw 104 drives the pusher column 102 to move towards the opposite rectangular opening 5 through the screw sleeve 103. The pusher column 102 enters the space between the fixed plate 402 and the movable plate 403 through the rectangular opening 5, and pushes the plastic bag fragments into pieces. The plastic bag fragments are fed into the discharge nozzle 8 through another set of rectangular openings 5. The discharge nozzle 8 guides the plastic bag fragments into the recycling bag. As the plastic bag fragments enter the recycling bag, the recycling bag, together with the plastic bag fragments, slides along the guide frame 9, realizing automatic bagging of the plastic bag fragments. After the plastic bag fragments are completely in the recycling bag, the pusher column 102 is retracted, and then the fixed plate 402 and the movable plate 403 are returned to the initial position. The above operation is repeated. When bagging the recycling bag, firstly, the end of the recycling bag is placed over the end of the discharge nozzle 8, positioning the end of the recycling bag between the four sets of rollers 113. Then, the four sets of second cylinders 114 push the corresponding movable frame 112 to move. The movable frame 112 drives the corresponding rollers 113 towards the recycling bag, clamping the recycling bag between the rollers 113 and the side of the discharge nozzle 8. Simultaneously, the first conical wheels 115 at the ends of the rollers 113 are in close contact with each other. During this process, the second conical wheels 116 move with the movable frame 112, and the rectangular shaft 117 moves along the first... The rectangular hole 1161 on the two conical wheels 116 slides, and then the second motor 119 drives the connector 118 and the rectangular shaft 117 to rotate together. The rectangular shaft 117 drives the second conical wheel 116 to rotate, and the second conical wheel 116 drives the corresponding first conical wheel 115 to rotate. The first conical wheel 115 drives the corresponding roller 113 to rotate. And because the first conical wheels 115 are in close contact with each other, the four sets of rollers 113 rotate simultaneously. The rotating rollers 113 drive the recycling bag to move, so that the recycling bag is quickly and automatically put on the discharge nozzle 8. When the recycling bag is being fitted, the limiting plate 1185 abuts against the drive disc 1183, compressing the second spring 1184. The second motor 119 drives the drive shaft 1182 to rotate. The drive shaft 1182, through the rectangular slot 82 and the guide block 84, drives the drive disc 1183 to rotate. The drive disc 1183, through the engagement of the locking block 83 and the locking slot 81, causes the driven disc 1181 to rotate. The driven disc 1181 drives the rectangular shaft 117 to rotate, thus quickly and automatically fitting the recycling bag onto the discharge nozzle 8. Before the clumps of plastic bag fragments enter the recycling bag, the electric push rod 1186 pulls the limiting plate 1185, releasing the compression of the second spring 1184 by the limiting plate 1185, and simultaneously moving the limiting plate 1185 away from the drive disc 1183. As the recycling bag moves along with the clumps of plastic bag fragments... When the length changes, the recycling bag drives the roller 113 to rotate. The roller 113 drives the second conical wheel 116 to rotate via a set of first conical wheels 115. The rotation of the second conical wheel 116 drives the driven disc 1181 to rotate via the rectangular shaft 117. Since the second motor 119 is energized, the driving disc 1183 cannot rotate. The slot 81 on the driven disc 1181 will squeeze the locking block 83, causing the driving disc 1183 to drive the guide block 84 to move along the rectangular groove 82 towards the limiting plate 1185. The driving disc 1183 compresses the second spring 1184. The rebound force of the second spring 1184 acts on the driving disc 1183, generating a damping effect on the rotation of the driven disc 1181. This damping effect causes the recycling bag to drive the roller 113 to rotate, and the roller 113 will pull the recycling bag in the opposite direction, straightening the recycling bag.
