Description

Technical Field

[0001] This invention mainly relates to the field of waste agricultural film recycling, specifically to a feeding device for waste agricultural film recycling and its usage method. Background Technology

[0002] Waste agricultural film recycling is a multi-stage collaborative system engineering project, covering multiple steps such as field collection, transportation, pretreatment, and granulation regeneration. Among them, the feeding stage is the core link between pretreatment and subsequent processing steps, and its operational stability and continuity directly determine the efficiency, energy consumption and processing effect of the entire recycling production line.

[0003] During the operation of specific embodiments, the inventors discovered the following defects: Because waste agricultural film has a loose structure and low bulk density, when using a belt conveyor for feeding, the material is prone to slipping and stratification during the conveying process, and it is difficult to form a stable material flow at the feeding end, often resulting in local accumulation or material interruption.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Summary of the Invention

[0005] 1. The technical problem that the invention aims to solve: This invention provides a feeding device for recycling waste agricultural film and its usage method, in order to solve the technical problems existing in the background art.

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by the present invention is as follows: a feeding device for recycling waste agricultural film and its usage method, comprising an agricultural film conveying structure, wherein a rotating structure is rotatably connected inside the agricultural film conveying structure, and agricultural film torsion structures are provided on both sides of the inner wall of the rotating structure. The agricultural film torsion structure includes an electric push rod and a rotating shaft. The number of rotating shafts is set to two, and a placement groove is provided in the middle of the rotating shaft. The rolling wheel is set to be dodecagonal.

[0007] Furthermore, the agricultural film conveying structure includes a housing, a discharge port at the bottom of the housing, an installation groove in the middle of the top of the housing, a servo motor on one side of the top of the housing, and a drive gear at the output end of the servo motor.

[0008] Furthermore, brackets are provided on both sides of the top of the housing, and a mounting plate is provided on the top of the brackets. An auxiliary groove is provided inside the mounting plate, and a compression wheel is provided inside the auxiliary groove.

[0009] Furthermore, the extrusion wheel is slidably connected to the auxiliary groove, and a spring is provided between the extrusion wheel and the auxiliary groove.

[0010] Furthermore, the rotating structure includes a rotating disk, a groove is provided in the middle of the outer wall of the rotating disk, the groove is rotatably connected to the inner wall of the mounting groove, and a meshing toothed ring is provided on the outer wall of the rotating disk, the meshing toothed ring meshing with the driving gear.

[0011] Furthermore, a positioning groove is provided in the middle of the rotating disk, and placement grooves are provided on both sides of the inner wall of the positioning groove.

[0012] Furthermore, the electric push rod is disposed on the inner wall of the placement groove, the output end of the electric push rod is provided with a connecting shaft, one end of the connecting shaft is provided with a mounting block, one end of the mounting block is provided with a drive motor, and the output end of the drive motor is connected to the rotating shaft.

[0013] Furthermore, the number of electric push rods is set to two, and a rotating shaft is provided between the two electric push rods.

[0014] A method of using a feeding device for recycling waste agricultural film, according to any of the described feeding devices for recycling waste agricultural film, includes the following steps: S1: Equipment debugging: Check the connection reliability of the agricultural film conveying structure, rotating structure and agricultural film torsion structure, test the start-stop and running status of servo motor, drive motor and electric push rod, add lubricating oil to the inner wall of the slide groove of the rotating plate to ensure that there is no jamming or abnormal noise in each component; S2: Agricultural film threading: After manually sorting and removing large impurities from the recycled waste agricultural film, it is threaded sequentially between the two extrusion rollers on the mounting plate and between the two rolling rollers in the positioning groove of the rotating disk, so that the lower end of the agricultural film is aligned with the discharge port at the bottom of the shell, ensuring that the agricultural film is not tangled. S3: Initial compression: Utilizing the elastic force of the spring in the auxiliary groove, the two compression rollers are pushed to come into contact with each other. The anti-slip texture on the outer circumference of the compression rollers is used to compress the agricultural film for the first time, so that the loose agricultural film comes into contact with each other and the dry dust and small soil particles attached to the surface of the agricultural film are squeezed off. S4: Spacing adjustment: Based on the thickness and looseness of the agricultural film, the controller starts the electric push rod. The electric push rod drives the mounting block, drive motor and rotating shaft to move synchronously through the connecting shaft, adjusting the distance between the two rolling wheels so that the rolling wheels fit the surface of the agricultural film without causing damage to the agricultural film. S5: Twist Tightening: Start the servo motor, which drives the drive gear to rotate. The drive gear drives the rotating disk to rotate around the mounting slot through the meshing gear ring. The rotating disk drives the agricultural film torsion structure on both sides to rotate synchronously. The vertical edge of the dodecagonal rolling wheel twists the agricultural film 360° during the rotation, so that the agricultural film is tightened to form a dense bundle of material, preventing it from loosening and slipping. S6: Drive feeding: Start the drive motor, which drives the rotating shaft and rolling wheel to rotate at a constant speed. Utilizing the friction between the edge of the rolling wheel and the agricultural film, the twisted agricultural film is continuously moved towards the discharge port. The material bundle is guided into the subsequent pretreatment process by the guide plate at the discharge port. S7: Operation Adjustment: Based on the material flow rate and uniformity at the discharge port, adjust the torsional speed of the servo motor, the conveying speed of the drive motor, and the extension and retraction of the electric push rod in real time to ensure that the feeding process is continuous and stable, without material interruption or accumulation.

[0015] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this invention has the following advantages: This invention uses a dodecagonal rolling wheel to rotate the inner agricultural film torsion structure 360° via a rotating structure on the outer wall. The vertical edge of the rolling wheel then twists the agricultural film to prevent it from becoming loose. Simultaneously, the rotation of the rolling wheel causes the twisted agricultural film to move downwards and twist subsequent agricultural films. An electric push rod can adjust the distance between the two rolling wheels to compress the agricultural film to different degrees, squeezing out the dust adhering to the inside of the agricultural film. The recycled agricultural film is placed between two extrusion rollers. A spring pushes the extrusion rollers to come together, giving the agricultural film an initial squeeze. This makes the loose agricultural film come together, which is convenient for subsequent twisting of the agricultural film and thus realizes the feeding of the agricultural film.

[0022] Example 1

[0023] See attached document Figure 1-4 A feeding device for recycling waste agricultural film and its usage method, comprising an agricultural film conveying structure 1, wherein a rotating structure 2 is rotatably connected inside the agricultural film conveying structure 1, and agricultural film torsion structures 3 are provided on both sides of the inner wall of the rotating structure 2. The agricultural film torsion structure 3 includes an electric push rod 301 and a rotating shaft 304. Two rotating shafts 304 are provided, each with a placement groove 205 in the middle. The rolling wheel 305 is dodecagonal. The electric push rod 301 is disposed on the inner wall of the placement groove 205. A connecting shaft 302 is provided at the output end of each electric push rod 301. A mounting block 303 is provided at one end of the connecting shaft 302, and a drive motor 306 is provided at one end of the mounting block 303. The output end of the drive motor 306 is connected to the rotating shaft 304. The two electric push rods 301... A rotating shaft 304 is provided between the rods 301. The agricultural film is placed between the two rolling wheels 305. Then, the electric push rod 301 is started. The electric push rod 301 drives the connecting shaft 302 to move inward. The connecting shaft 302 drives the rotating shaft 304 to move inward. The rotating shaft 304 drives the rolling wheels 305 to squeeze the agricultural film. When the edge of the rolling wheel 305 contacts the agricultural film, the rotating disk 201 drives the agricultural film torsion structure 3 to rotate as a whole, so that the rolling wheels 305 torsion the agricultural film. Then, the drive motor 306 is started. The drive motor 306 drives the rotating shaft 304 to rotate. The rotating shaft 304 drives the rolling wheels 305 to rotate and feed the torsioned agricultural film.

[0024] Furthermore, the agricultural film conveying structure 1 includes a housing 101, a discharge port 102 at the bottom of the housing 101, an installation groove 103 in the middle of the top of the housing 101, a servo motor 104 on one side of the top of the housing 101, a drive gear 105 at the output end of the servo motor 104, brackets 106 on both sides of the top of the housing 101, an installation plate 107 on the top of the brackets 106, an auxiliary groove 108 inside the installation plate 107, a squeezing wheel 109 inside the auxiliary groove 108, a sliding connection between the squeezing wheel 109 and the auxiliary groove 108, and a spring between the squeezing wheel 109 and the auxiliary groove 108. When it is necessary to recycle and feed the old agricultural film, the agricultural film is passed between two squeezing wheels 109, and then between two agricultural film torsion structures 3. After that, the agricultural film torsion structure 3 twists the agricultural film and pushes it downward to tighten the loose agricultural film before feeding. As the agricultural film moves downward, it drives the extrusion roller 109 to rotate. At the same time, the spring pushes the extrusion roller 109 to extrude the agricultural film, so that the loose agricultural film can stick together and extrude the dry soil inside, causing the soil to fall off the surface of the agricultural film. Then start the servo motor 104, which drives the drive gear 105 to rotate, and the drive gear 105 drives the rotating structure 2 to rotate.

[0025] Furthermore, the rotating structure 2 includes a rotating disk 201. A sliding groove 202 is provided in the middle of the outer wall of the rotating disk 201. The sliding groove 202 is rotatably connected to the inner wall of the mounting groove 103. A meshing toothed ring 203 is provided on the outer wall of the rotating disk 201. The meshing toothed ring 203 meshes with the drive gear 105. A positioning groove 204 is provided in the middle of the rotating disk 201. Placement grooves 205 are provided on both sides of the inner wall of the positioning groove 204. The rotation of the drive gear 105 drives the rotating disk 201 to rotate on the inner wall of the mounting groove 103 through the meshing toothed ring 203. The rotating disk 201 drives the internal agricultural film torsion structure 3 to rotate. The rotation of the agricultural film torsion structure 3 is used to torsion the agricultural film between the two agricultural film torsion structures 3, so that the agricultural film can stick together.

[0026] A method of using a feeding device for recycling waste agricultural film, according to any of the described feeding devices for recycling waste agricultural film, includes the following steps: S1: Equipment debugging: Check the connection reliability of agricultural film conveying structure 1, rotating structure 2 and agricultural film torsion structure 3, test the start-stop and running status of servo motor 104, drive motor 306 and electric push rod 301, add lubricating oil to the inner wall of the slide groove 202 of rotating disk 201 to ensure that there is no jamming or abnormal noise in each component; S2: Agricultural film threading: After manually sorting and removing large impurities, the recycled waste agricultural film is threaded through the two extrusion rollers 109 on the mounting plate 107 and the two rolling rollers 305 in the positioning groove 204 of the rotating disk 201, so that the lower end of the agricultural film is aligned with the discharge port 102 at the bottom of the housing 101, ensuring that the agricultural film is not tangled. S3: Initial compression: Using the elastic force of the spring in the auxiliary groove 108, the two compression rollers 109 are pushed to stick together. The anti-slip texture on the outer circumference of the compression rollers 109 is used to compress the agricultural film for the first time, so that the loose agricultural film sticks together and squeezes off the dry dust and small soil particles attached to the surface of the agricultural film. S4: Spacing adjustment: Based on the thickness and looseness of the agricultural film, the electric push rod 301 is activated by the controller. The electric push rod 301 drives the mounting block 303, drive motor 306 and rotating shaft 304 to move synchronously through the connecting shaft 302, adjusting the distance between the two rolling wheels 305 so that the rolling wheels 305 are in contact with the surface of the agricultural film without causing damage to the agricultural film. S5: Twist Tightening: Start the servo motor 104, which drives the drive gear 105 to rotate. The drive gear 105 drives the rotating disk 201 to rotate around the mounting groove 103 through the meshing gear ring 203. The rotating disk 201 drives the agricultural film twisting structure 3 on both sides to rotate synchronously. The vertical edge of the dodecagonal rolling wheel 305 twists the agricultural film 360° during the rotation, so that the agricultural film is tightened to form a dense bundle of material, preventing it from loosening and slipping. S6: Drive feeding: Start the drive motor 306. The drive motor 306 drives the rotating shaft 304 and the rolling wheel 305 to rotate at a constant speed. Utilize the friction between the side of the rolling wheel 305 and the agricultural film to drive the twisted agricultural film to move continuously toward the discharge port 102. The material bundle is guided into the subsequent pretreatment process by the guide plate of the discharge port 102. S7: Operation Adjustment: Based on the material flow speed and uniformity at the discharge port 102, adjust the torsional speed of the servo motor 104, the conveying speed of the drive motor 306, and the extension and retraction of the electric push rod 301 in real time to ensure that the feeding process is continuous and stable, without material interruption or accumulation.

[0027] Equipment startup preparation and commissioning First, a comprehensive inspection of the entire waste agricultural film recycling and feeding equipment was conducted to confirm that the bottom support feet of the housing 101 of the agricultural film conveying structure 1 were firmly fixed without any loosening or displacement. The start-stop response of the servo motor 104 and drive motor 306 was verified one by one to ensure sensitivity, and the extension and retraction stroke of the electric push rod 301 was accurate, ensuring that each power component operated without jamming or abnormal noise. Simultaneously, the fit between the sliding groove 202 of the rotating disk 201 in the rotating structure 2 and the mounting groove 103 on the top of the housing 101 was checked, and lubricating oil was evenly applied to the inner wall of the sliding groove 202 to reduce rotational friction. Residual impurities on the surface of the extrusion wheel 109 and inside the auxiliary groove 108 were cleaned, confirming that the spring elasticity had returned to normal and there was no deformation or failure. Finally, the recycled waste agricultural film was manually sorted to remove large impurities such as stones and metal fragments to prevent damage to equipment components during subsequent operations.

[0028] Agricultural film feeding and initial extrusion pretreatment The sorted waste agricultural film is inserted between the two compression rollers 109 of the top mounting plate 107 of the support 106. With the help of the elastic thrust of the spring in the auxiliary groove 108, the compression rollers 109 automatically adhere to the surface of the agricultural film. The anti-slip texture on the outer circumference of the compression rollers 109 increases the friction with the agricultural film. As the agricultural film moves downward under the subsequent traction, it drives the compression rollers 109 to rotate synchronously. During the rotation and compression process, the loose agricultural film is gradually compacted and adhered, and the dry dust and small soil clods attached to its surface are squeezed off, achieving the initial purification and densification of the agricultural film. Subsequently, the agricultural film continues to extend downward, passing through the positioning groove 204 in the middle of the rotating disk 201, and entering between the dodecagonal rolling rollers 305 of the two agricultural film torsion structures 3. The positioning groove 204 plays a guiding role, ensuring that the agricultural film is always in the center of the working position and avoiding deviation and entanglement.

[0029] 305 roller spacing adapts to agricultural film twisting and tightening Based on the actual thickness and looseness of the agricultural film, the extension and retraction of the electric push rod 301 is adjusted by the equipment controller. The electric push rod 301 is fixed in the placement groove 205 on the inner wall of the positioning groove 204. Its output end drives the mounting block 303 and the drive motor 306 to move synchronously through the connecting shaft 302, thereby adjusting the distance between the dodecagonal rolling wheels 305 on the two rotating shafts 304, so that the rolling wheels 305 are in close contact with the surface of the agricultural film, which ensures the torsion effect without causing damage to the agricultural film. After the spacing is adjusted, the servo motor 104 is started. The output end of the servo motor 104 drives the drive gear 105 to rotate. The drive gear 105 meshes with the meshing gear ring 203 on the outer wall of the rotating disk 201, driving the rotating disk 201 to rotate stably around the mounting groove 103. The rotating disk 201 synchronously drives the agricultural film torsion structure 3 on both sides to rotate as a whole. The vertical edge of the dodecagonal rolling wheel 305 forms a periodic compression and torsion on the agricultural film during the rotation, gradually tightening the loose agricultural film into a dense bundle, completely solving the problem of agricultural film slipping and delamination.

[0030] Power conveying and stable material discharge After the agricultural film is twisted and tightened, the drive motor 306 is started. The output end of the drive motor 306 drives the rotating shaft 304 and the rolling wheel 305 mounted on it to rotate at a constant speed. Utilizing the friction between the edge of the rolling wheel 305 and the agricultural film bundle, a continuous downward traction force is generated, causing the twisted agricultural film bundle to move smoothly. During this process, the rotation of the rolling wheel 305 and the rotation of the rotating disk 201 work together to ensure both the continuous tightening of the agricultural film bundle and stable conveying, avoiding material breakage or local accumulation. Finally, the agricultural film bundle is output through the discharge port 102 at the bottom of the housing 101. The guide plate on the inner wall of the discharge port 102 guides the bundle precisely into the subsequent pretreatment or granulation and regeneration process, completing the entire feeding process.

[0031] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
