Description

Technical Field

[0001] This invention relates to the field of plastic film processing, and more particularly to a plastic film recycling and processing device for greenhouses. Background Technology

[0002] As is generally known, the recycling process of plastic film mainly involves the steps of recycling, washing, crushing, and reprocessing. In the crushing step, a crusher is often used for crushing.

[0003] For example, the authorization announcement number is CN106827304B, the authorization announcement date is 2018.10.26, the name is plastic bag crusher, there are crushing blades in the crushing box, there is a motor in the crushing box, the motor shaft is connected to the crushing blades by a belt, there is a conveyor frame above the motor, there are driving rollers and driven rollers connected by a conveyor belt on the conveyor frame, there are contact blocks on the conveyor belt, there is a first bevel gear on the shaft, there is a second bevel gear on the driving roller that meshes with the first bevel gear, there is a third bevel gear on the driven roller, there is a feeding channel in front of the conveyor belt, there is a fourth bevel gear at the upper end of the feeding channel that meshes with the third bevel gear, the inner side of the fourth bevel gear is conical and there is a scraper on the inner side wall, there is a feeding hopper with a valve above the fourth bevel gear, etc.

[0004] As with the above applications, in existing processing equipment for broken film / bags, the specific gravity of the broken film / bags is relatively light, making discharge inconvenient. Furthermore, when the broken film / bags are crushed, they often contain water and high-density impurities, requiring dehydration and impurity removal processes after crushing, which increases the number of steps and processing costs. Moreover, after the existing broken film / bags are crushed, the broken film / bags mix with water and easily adhere to the inside of the crushing equipment, affecting the discharge efficiency. Summary of the Invention

[0005] (a) Purpose of the invention

[0006] In view of this, the purpose of this invention is to provide a plastic film recycling and processing device for greenhouses, so as to achieve the effects of rapid material discharge and avoid plastic film adhering to the inside of the equipment.

[0007] (II) Technical Solution

[0008] To achieve the above technical objectives, the present invention provides a plastic film recycling and processing device for greenhouses, which includes a crushing chamber, a crushing room is provided inside the crushing room, and a moving crushing roller is rotatably installed in the crushing room via a crushing shaft, and a fixed crushing roller is fixedly installed. The surfaces of the moving crushing roller and the fixed crushing roller are provided with interlaced blade structures for crushing the plastic film.

[0009] The sorting chamber is installed below the crushing chamber. The sorting chamber has an air duct inside, and an impeller is installed at one end of the air duct. The two ends of the impeller are rotatably mounted on the inner wall of the air duct through an impeller shaft.

[0010] The air duct is connected to the crushing chamber, and one of the impeller shafts is connected to the crushing shaft via a second transmission belt. A drive motor for driving the crushing shaft is installed outside the sorting bin. This processing device is mainly used for crushing and sorting recycled plastic film. In use, the plastic film to be crushed first enters the crushing chamber from the top. At this time, the drive motor runs and drives the moving crushing roller to rotate through the crushing shaft. Under the action of the blade structure on the surface of the moving crushing roller and the fixed crushing roller, the plastic film is crushed and moves downward. While the crushing shaft is rotating, it drives the impeller to rotate through the second transmission belt and the impeller shaft, which increases the air speed in the air duct. Therefore, the air pressure in the air duct area decreases, thereby accelerating the discharge of the crushed plastic film from the other end of the air duct and improving the crushing efficiency.

[0011] As a further description of the above technical solution: the sorting chamber is further provided with a water filtration channel and a filter residue channel below the air duct. The filter residue channel is located below the water filtration channel. Both the water filtration channel and the filter residue channel adopt an inclined structure with the height gradually decreasing from the inside to the outside of the sorting chamber. The high end of the water filtration channel is connected to the air duct through a water filtration trough, and the high end of the filter residue channel is connected to the air duct through a filter residue trough. This structural arrangement allows the plastic film to fall into the air duct after being broken. Since the plastic film is relatively light, it will be blown out from one end of the air duct. Most of the water mixed in with the plastic film will enter the water filtration channel through the water filtration trough and be discharged. The heavy impurities mixed in will enter the filter residue channel through the filter residue trough and be discharged, thus achieving the separation of plastic film, water, and heavy impurities.

[0012] As a further description of the above technical solution: the air duct adopts an inclined structure with the height gradually increasing from the inside of the sorting chamber to the outside. The filter residue tank is located at the lowest end of the air duct. This structural setting allows the broken plastic film to fall into the air duct and be blown outward. Because the plastic film has a low specific gravity, it will be blown upward along the slope. Meanwhile, the water and high specific gravity impurities in the plastic film will be guided by the slope and enter the water filtration tank and filter residue tank to be discharged through the water filtration channel and filter residue channel, thereby improving the sorting effect and facilitating the subsequent secondary processing of the plastic film.

[0013] As a further description of the above technical solution: the water filter tank is opened along the airflow direction of the air duct, and several channels are opened along the airflow direction perpendicular to the air duct. A feeding auxiliary mechanism is also installed in the water filter channel. The feeding auxiliary mechanism can reciprocate along the length of the water filter tank to lift the plastic film on the surface of the water filter tank. Therefore, when the plastic film is attached to the surface of the water filter tank, the feeding auxiliary mechanism can lift the plastic film, so that the plastic film and the airflow direction of the air duct form an angle, making it easy to be blown out, thereby achieving the effect of avoiding clogging of the water filter tank and facilitating the blowing out of the plastic film.

[0014] As a further description of the above technical solution: the feeding auxiliary mechanism includes a movable plate and feeding guide rods. The movable plate is installed horizontally along the airflow direction perpendicular to the air duct. The feeding guide rods are fixed above the movable plate. The number of feeding guide rods is the same as the number of water filter tanks, and they are inserted into each water filter tank one by one. Since the air duct adopts an inclined structure with the height gradually increasing from the inside to the outside of the sorting bin, when the movable plate moves back and forth in the horizontal direction, the closer the movable plate is to the outside of the sorting bin, the shorter the length of the top of the feeding guide rod protruding from the surface of the air duct. When it reaches the outermost position, it is completely retracted into the water filter tank. Conversely, the closer the movable plate is to the inside of the sorting bin, the longer the length of the top of the feeding guide rod protruding from the surface of the air duct. Therefore, when the movable plate moves back and forth, it can continuously rise and fall relative to the surface of the air duct, avoiding plastic film from adhering to the surface of the air duct, thus achieving the effect of avoiding clogging of the water filter tank and facilitating the blowing out of the plastic film.

[0015] As a further description of the above technical solution: sliders are installed at both ends of the movable plate, and guide grooves are opened on both sides of the sorting bin located on both sides of the water filtration channel. The sliders are slidably installed in the guide grooves, so the feeding auxiliary mechanism can reciprocate along the direction of the guide grooves. Specifically, in order to make the feeding auxiliary mechanism reciprocate more smoothly, balls are embedded in the top and bottom of the sliders, and auxiliary ball grooves adapted to the balls are opened on the inner wall of the guide grooves. The balls can roll in the auxiliary ball grooves, so the feeding auxiliary mechanism can reciprocate more smoothly.

[0016] As a further description of the above technical solution: the feeding auxiliary mechanism and the impeller shaft are connected by a linkage mechanism, the linkage mechanism including:

[0017] A turntable is fixedly installed at one end of the impeller shaft, and an eccentric shaft is mounted on the surface of the turntable.

[0018] A push shaft is fixedly installed at one end of the slider;

[0019] The eccentric shaft and the push shaft are connected by a connecting rod. The connection between the eccentric shaft, the push shaft, and the connecting rod is rotatably connected by bearings. When the turntable rotates, since one end of the connecting rod is rotatably mounted on the eccentric shaft, and the push shaft can only slide in the direction of the guide groove, the slider can reciprocate in the guide groove under the drive of the connecting rod and the push shaft. This realizes the reciprocating control of the feeding auxiliary mechanism. Furthermore, the driving structure of the feeding auxiliary mechanism, the impeller driving structure, and the driving structure of the moving crushing roller are all driven by the same drive, so the synchronization rate of the three is high and the operating cost of the equipment is low.

[0020] As a further description of the above technical solution: a drive wheel is installed on the output shaft of the drive motor, and the drive wheel is connected to one of the crushing shafts through a first transmission belt. Therefore, when the drive motor is running, it can drive the crushing shaft to rotate, thereby driving the crushing roller to rotate and perform the crushing operation of the plastic film.

[0021] As a further description of the above technical solution: the difference between the width of the feeding guide rod and the width of the filter tank is less than the thickness of the plastic film, and the cross-section of the feeding guide rod is triangular. Therefore, when the feeding guide rod is retracted into the filter tank, it can scrape off the plastic film "hanging" on the feeding guide rod, ensuring that it can be blown out from the air duct.

[0022] As a further description of the above technical solution: a hopper is installed on the top of the crushing chamber, and the hopper adopts a narrow structure with the opening gradually decreasing from top to bottom.

[0023] In the above technical solution, the present invention provides a plastic film recycling and processing device for greenhouses. This device installs an impeller inside the sorting bin, so that the discharge channel of the sorting bin forms an air duct. Therefore, when the impeller rotates, the wind speed in the air duct increases and the air pressure in the air duct area decreases, thereby accelerating the discharge of the crushed plastic film from the other end of the air duct, improving the crushing efficiency, and avoiding the plastic film from being squeezed and accumulated in the sorting bin. At the same time, when the plastic film is blown out, some impurities with a larger specific gravity mixed in the plastic film are left at the bottom of the air duct, achieving the sorting effect, reducing the subsequent plastic film processing steps, and reducing processing costs. In addition, the impeller and the moving crushing roller in this device adopt a linkage structure, so the impeller does not need to be driven by other additional drive equipment, reducing the structure of the equipment and reducing the cost of use and production.

[0024] This device features a water filter tank within the sorting chamber, which filters out most of the water from the plastic film, separating it from the water and facilitating subsequent processing. To prevent the plastic film from adhering to the surface of the water filter tank after getting wet, the device employs a unique design for the water filter tank and air duct, along with a feeding auxiliary mechanism installed below the water filter tank to assist in pushing the film and prevent adhesion. When the plastic film adheres to the surface of the water filter tank, the feeding auxiliary mechanism lifts it up, creating an angle between the film and the airflow direction in the air duct, making it easier to blow out. This achieves the effects of preventing clogging of the water filter tank and facilitating the removal of the plastic film. Furthermore, the drive structure of the feeding auxiliary mechanism, the impeller drive structure, and the moving crushing roller drive structure all share the same drive, resulting in high synchronization and low operating costs.

[0034] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0035] Example 1: As Figure 1 - Figure 7 As shown: This embodiment provides a technical solution: a plastic film recycling and processing device for greenhouses, including a crushing chamber 2 and a sorting chamber 1. The crushing chamber 2 is provided with a crushing chamber 200 inside, and a moving crushing roller 201 is rotatably installed in the crushing chamber 200 via a crushing shaft 4, and a fixed crushing roller 202 is fixedly installed. The surfaces of the moving crushing roller 201 and the fixed crushing roller 202 are provided with interlaced blade structures for crushing the plastic film. The sorting chamber 1 is installed below the crushing chamber 2, and an air duct 100 is provided inside the sorting chamber 1. An impeller 8 is provided at one end of the air duct 100, and both ends of the impeller 8 are rotatably installed on the inner wall of the air duct 100 via impeller shafts 801. The air duct 100 is connected to the crushing chamber 200. One of the impeller shafts 801 is connected to the crushing shaft 4 via a second transmission belt 9. A drive motor 7 for driving the crushing shaft 4 to rotate is installed outside the sorting chamber 1.

[0036] By adopting the above technical solution:

[0037] This processing device is mainly used for crushing and sorting recycled plastic film. In operation, the plastic film to be crushed first enters the crushing chamber 200 from above. At this time, the drive motor 7 runs, driving the moving crushing roller 201 to rotate via the crushing shaft 4. Under the action of the blade structure on the surfaces of the moving crushing roller 201 and the fixed crushing roller 202, the plastic film is crushed and moves downwards. Simultaneously, the crushing shaft 4 rotates, driving the impeller 8 to rotate via the second transmission belt 9 and the impeller shaft 801, thus increasing the air velocity within the air duct 100 and reducing the air pressure in the air duct 100 area. This accelerates the discharge of the crushed plastic film from the other end of the air duct 100, improving crushing efficiency. It also prevents the plastic film from being squeezed and accumulated in the sorting chamber 1. When the plastic film is blown out, some heavier impurities mixed in with the plastic film are left at the bottom of the air duct 100, achieving the sorting effect, reducing subsequent plastic film processing steps, and lowering processing costs. At the same time, the impeller 8 and the moving crushing roller 201 in this device adopt a linkage structure, so the impeller 8 does not require other additional drive equipment to drive it, reducing the structure of the equipment and lowering the cost of use and production.

[0038] Specifically, such as Figure 3 - Figure 4 As shown, since plastic film generally contains a lot of water and debris during recycling, in order to separate the water and some heavier debris, in this embodiment, a water filtration channel 102 and a filter cake channel 103 are respectively provided inside the sorting chamber 1 below the air duct 100. The filter cake channel 103 is located below the water filtration channel 102. Both the water filtration channel 102 and the filter cake channel 103 adopt an inclined structure with a gradually decreasing height from the inside to the outside of the sorting chamber 1. The high end of the water filtration channel 102 is connected to the air duct 100. The filter tank 1011 is connected, and the high end of the filter cake channel 103 is connected to the air duct 100 through the filter cake tank 1010. This structure allows the plastic film to fall into the air duct 100 after being broken. Because the plastic film is relatively light, it will be blown out from one end of the air duct 100. Most of the water mixed in the plastic film will enter the filter channel 102 through the filter tank 1011 and be discharged. The heavy impurities mixed in will enter the filter cake channel 103 through the filter cake tank 1010 and be discharged, thus achieving the separation of plastic film, water and heavy impurities.

[0039] Specifically, such as Figure 3 - Figure 4As shown, in order to improve the separation effect of plastic film, water, and high-density impurities, in this embodiment, the air duct 100 adopts an inclined structure with the height gradually increasing from the inside to the outside of the sorting chamber 1. The filter residue tank 1010 is located at the lowest end of the air duct 100. This structural setting allows the broken plastic film to fall into the air duct 100 and be blown outward. Since the plastic film has a low density, it will be blown upward along the slope. The water and high-density impurities in the plastic film will be guided by the slope and enter the water filtration channel 102 and the filter residue channel 103 through the water filtration tank 1011 and the filter residue tank 1010 for discharge, thereby improving the sorting effect and facilitating the subsequent secondary processing of the plastic film. It should be noted that the entry of some water or small impurities into the filter residue channel 103 and the water filtration channel 102 will not affect the subsequent processing.

[0040] Example 2: Figure 1 - Figure 7 As shown: This embodiment provides a technical solution: Based on embodiment 1, since the broken plastic film contains water, it is easy for the plastic film to stick directly to the surface of the air duct 100 when it falls, causing the plastic film to be unable to be blown out and clogging the water filter tank 1011. In this embodiment, the water filter tank 1011 is opened along the air flow direction of the air duct 100, and several lines are opened along the air flow direction perpendicular to the air duct 100. A feeding auxiliary mechanism 11 is also installed in the water filter channel 102. The feeding auxiliary mechanism 11 can reciprocate along the length direction of the water filter tank 1011 to lift the plastic film on the surface of the water filter tank 1011. Therefore, when the plastic film is attached to the surface of the water filter tank 1011, the feeding auxiliary mechanism 11 can lift the plastic film, so that the plastic film and the air flow direction of the air duct 100 form an angle, making it easy to be blown out, thereby achieving the effect of avoiding clogging of the water filter tank 1011 and facilitating the blowing out of the plastic film.

[0041] Specifically, such as Figure 3 , Figure 6As shown, in order to enable the feeding auxiliary mechanism 11 to lift the plastic film attached to the surface of the filter tank 1011, in this embodiment, the feeding auxiliary mechanism 11 includes a movable plate 1101 and a feeding guide rod 1100. The movable plate 1101 is horizontally installed along the airflow direction perpendicular to the air duct 100. The feeding guide rod 1100 is fixed above the movable plate 1101. The number of feeding guide rods 1100 is the same as the number of filter tanks 1011, and they are inserted into each filter tank 1011 in a corresponding manner. Since the air duct 100 adopts an inclined structure with a gradually increasing height from the inside to the outside of the sorting chamber 1, the movable plate 1101, along the horizontal direction... When the movable plate 1101 moves back and forth, the closer the movable plate 1101 is to the outer side of the sorting bin 1, the shorter the length of the top of the feeding guide rod 1100 protruding from the surface of the air duct 100. When it reaches the outermost position, it is completely retracted into the water filter tank 1011. Conversely, the closer the movable plate 1101 is to the inner side of the sorting bin 1, the longer the length of the top of the feeding guide rod 1100 protruding from the surface of the air duct 100. Therefore, when the movable plate 1101 moves back and forth, it can continuously rise and fall relative to the surface of the air duct 100, avoiding the adhesion of plastic film to the surface of the air duct 100, thus achieving the effect of avoiding clogging of the water filter tank 1011 and facilitating the blowing out of the plastic film.

[0042] Specifically, such as Figure 3 , Figure 6 As shown, in order to enable the feeding auxiliary mechanism 11 to reciprocate, in this embodiment, sliders 1102 are installed at both ends of the movable plate 1101, and guide grooves 104 are provided on both sides of the sorting bin 1 at the positions on both sides of the water filtration channel 102. The sliders 1102 are slidably installed in the guide grooves 104, so the feeding auxiliary mechanism 11 can reciprocate along the direction of the guide grooves 104. Specifically, in order to make the feeding auxiliary mechanism 11 reciprocate more smoothly, balls 1103 are embedded in the top and bottom of the sliders 1102, and auxiliary ball grooves 1040 adapted to the balls 1103 are provided on the inner wall of the guide grooves 104. The balls 1103 can roll in the auxiliary ball grooves 1040, so the feeding auxiliary mechanism 11 can reciprocate more smoothly.

[0043] Example 3: As Figure 1 - Figure 7As shown: This embodiment provides a technical solution: Based on embodiment 2, in order to achieve reciprocating control of the feeding auxiliary mechanism 11, in this embodiment, the feeding auxiliary mechanism 11 and the impeller shaft 801 are connected by a linkage mechanism 10. The linkage mechanism 10 includes a turntable 1001 and a push shaft 1003. The turntable 1001 is fixedly installed at one end of the impeller shaft 801, and an eccentric shaft 1000 is installed on the surface of the turntable 1001. The push shaft 1003 is fixedly installed at one end of the slider 1102. The eccentric shaft 1000 and the push shaft 1003 are connected by a connecting rod 1002. The connection between 03 and connecting rod 1002 is rotatably connected by bearings. When turntable 1001 rotates, since one end of connecting rod 1002 is rotatably mounted on eccentric shaft 1000, and push shaft 1003 can only slide in the direction of guide groove 104, the slider 1102 can reciprocate in guide groove 104 under the drive of connecting rod 1002 and push shaft 1003, thereby realizing the reciprocating control of feeding auxiliary mechanism 11. Furthermore, the driving structure of feeding auxiliary mechanism 11, impeller 8 and moving crushing roller 201 are all the same drive, so the synchronization rate of the three is high and the operating cost of the equipment is low.

[0044] Specifically, such as Figure 1 - Figure 5 As shown, in order to control the moving crushing roller 201, in this embodiment, a drive wheel 5 is installed on the output shaft of the drive motor 7. The drive wheel 5 is connected to one of the crushing shafts 4 by a first transmission belt 6. Therefore, when the drive motor 7 is running, it can drive the crushing shaft 4 to rotate, thereby driving the moving crushing roller 201 to rotate and perform the crushing operation of the plastic film.

[0045] Specifically, such as Figure 3 , Figure 6 As shown, in order to prevent the plastic film from "hanging" on the feeding guide rod 1100, in this embodiment, the difference between the width of the feeding guide rod 1100 and the width of the filter tank 1011 is less than the thickness of the plastic film, and the cross-section of the feeding guide rod 1100 is triangular. Therefore, when the feeding guide rod 1100 is retracted into the filter tank 1011, it can scrape off the plastic film "hanging" on the feeding guide rod 1100, ensuring that it can be blown out from the air duct 100.

[0046] Specifically, such as Figure 1 - Figure 3 As shown, in order to facilitate the rapid entry of the plastic film into the crushing chamber 200, in this embodiment, a hopper 3 is installed on the top of the crushing chamber 2. The hopper 3 adopts a narrow structure with the opening gradually decreasing from top to bottom.

[0047] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
