Description

Technical Field

[0001] This utility model relates to the field of agricultural film processing technology, specifically to an anti-sticking conveyor roller structure for agricultural film processing. Background Technology

[0002] In the field of agricultural film processing, the conveyor roller is a core component connecting continuous processes such as extrusion, blow molding, cooling, and cutting. Its main function is to carry and pull the formed agricultural film, ensuring that the film is stably transported along a preset path, and providing a basic guarantee for subsequent processing stages.

[0003] However, in practical applications, agricultural films are mostly made of thermoplastic resins such as polyethylene and polyvinyl chloride. After extrusion or blow molding, the film surface still retains a certain amount of residual heat. When thermoplastic resins are not completely cooled, they tend to become sticky, causing the film to adhere tightly to the roller surface, forming a "roller sticking" phenomenon. This can lead to uneven film conveying speed, and even cause film wrinkles and tears, forcing the production line to stop and manually clean the film residue adhering to the roller, thus extending the overall processing cycle.

[0004] Therefore, a structure for an anti-sticking conveyor roller in agricultural film processing is proposed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an anti-sticking conveyor roller structure for agricultural film processing, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution.

[0007] This utility model provides an agricultural film processing anti-sticking conveyor roller structure, including a roller body and mounting shafts disposed at both ends of the roller body, and a plurality of evenly distributed ventilation grooves are formed on the surface of the roller body along its length direction;

[0008] One of the mounting shafts has a hollow air blowing plate rotatably mounted on one end away from the roller body. The hollow air blowing plate has multiple evenly distributed air blowing holes around one side facing the roller body, and an air blowing pipe connector is fixedly mounted on the circumferential wall of the hollow air blowing plate.

[0009] Preferably, the roller body has a hollow structure, and both ends of the roller body are provided with multiple evenly distributed ventilation openings.

[0010] Preferably, the positions of the plurality of ventilation slots, the positions of the plurality of ventilation openings, and the positions of the plurality of air blowing holes are distributed in a one-to-one correspondence.

[0011] Preferably, one end of the blower connector is connected to an external ion blower via an air guide pipe.

[0012] Preferably, the hollow blower plate has two mounting blocks symmetrically fixed on its circumferential wall, and the mounting blocks are provided with mounting holes.

[0013] Preferably, the mounting shaft at the end furthest from the hollow blower plate is connected to an external drive assembly.

[0014] Preferably, the surface of the roller body is provided with a ceramic coating.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] Airflow generated by an external ion blower enters the hollow blower plate through the blower pipe connector, and then enters the interior of the roller body through the blower holes and ventilation ports at both ends of the roller body, reducing the internal temperature of the roller body. Then, it acts evenly on the contact area between the film and the roller body through the ventilation grooves on the surface of the roller body, forming a stable air cushion layer and reducing the direct contact area between the two. At the same time, the ion airflow can neutralize the static electricity on the film surface. Combined with the low surface adhesion of the ceramic coating on the roller body surface, it cuts off the causes of adhesion from three aspects: physical isolation, static electricity elimination, and material adhesion reduction. This avoids film wrinkles, tears, and production line shutdowns for cleaning, ensuring a continuous process for agricultural film processing and improving production efficiency.

[0022] A structure for an anti-sticking conveyor roller in agricultural film processing, such as Figure 1-4As shown, the assembly includes a roller body 1 and mounting shafts 2 at both ends of the roller body 1. Multiple evenly distributed ventilation slots 3 are formed along the length of the roller body 1. A hollow air blower 4 is rotatably mounted on one end of the mounting shaft 2 away from the roller body 1. Multiple evenly distributed air holes 5 are formed around the side of the hollow air blower 4 facing the roller body 1. An air pipe connector 6 is fixed to the circumferential wall of the hollow air blower 4, and one end of the air pipe connector 6 is connected to an external ion fan via a guide pipe. Two mounting blocks 8 are symmetrically fixed to the circumferential wall of the hollow air blower 4, and mounting holes 9 are provided on the mounting blocks 8. Bolts are inserted into the mounting holes 9 to fix the hollow air blower 4 to the corresponding position on the processing production line. The mounting shaft 2 at the end away from the hollow air blower 4 is connected to an external drive assembly. The roller body 1 has a hollow structure, and multiple evenly distributed ventilation openings 7 are formed around both ends of the roller body 1. The positions of the multiple ventilation slots 3, the multiple ventilation openings 7, and the multiple air holes 5 are distributed in a one-to-one correspondence.

[0023] The surface of the roller 1 is provided with a ceramic coating (not shown in the figure). The ceramic coating, such as an alumina ceramic coating, is prepared on the surface of the roller 1 using plasma spraying technology. The ceramic coating has high hardness and strong chemical stability, which can resist the heat and mechanical wear generated by film friction. At the same time, its smooth surface can reduce the contact area between the film and the roller and inhibit adhesion.

[0024] In summary: When using this agricultural film to process the anti-sticking conveyor roller structure, first connect the roller body 1 to the external drive assembly through the mounting shaft 2. At the same time, use the mounting block 8 on the circumferential wall of the hollow blower plate 4 and the mounting hole 9 on the mounting block 8 to fix the hollow blower plate 4 in the corresponding position of the processing production line. Then connect the hollow blower plate 4 to the air guide pipe of the external ion blower through the blower pipe connector 6.

[0025] After the equipment is started, the external drive component drives the mounting shaft 2 to rotate, and the mounting shaft 2 further drives the roller 1 to rotate synchronously. During the rotation, the roller 1 plays a role in bearing and traction of the agricultural film, ensuring that the film is stably transported along the preset path. At the same time, the external ion fan is started, and the generated airflow is transported to the interior of the hollow blower plate 4 through the air guide pipe. The multiple blow holes 5 opened around the side of the hollow blower plate 4 facing the roller 1 will blow the airflow in a direction towards the roller 1.

[0026] Because the roller body 1 adopts a hollow structure, and multiple ventilation openings 7 are provided around both ends of the roller body 1, and multiple ventilation grooves 3 are provided on the surface of the roller body 1 along its length, and the positions of the ventilation grooves 3, ventilation openings 7 and air blowing holes 5 are distributed in a one-to-one correspondence, the airflow blown out from the air blowing holes 5 of the hollow air blowing plate 4 can pass through the ventilation openings 7 at both ends of the roller body 1 and enter the interior of the roller body 1 in sequence, reducing the temperature inside the roller body 1. At the same time, the airflow acts evenly on the contact area between the surface of the roller body 1 and the film through the ventilation grooves 3 on the surface of the roller body 1. The airflow forms a stable air cushion layer here, reducing the direct contact area between the film and the surface of the roller body 1, reducing the adhesion force of the film caused by residual stickiness, and the airflow of the ion blower can neutralize the static electricity generated during the processing of the film surface, further avoiding the adsorption and adhesion caused by static electricity.

[0027] In addition, the surface of the roller 1 is coated with a ceramic coating. This coating itself has low surface adhesion, which can help reduce the adhesion between the film and the roller 1 from the material level. Through the synergistic effect of the airflow cushion layer, static electricity neutralization and ceramic coating, the film is ensured to detach smoothly from the roller 1 during transmission, effectively avoiding the phenomenon of sticking to the roller.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
