Description

Technical Field

[0001] This utility model relates to the field of cover film production technology, and in particular to a drying device for cover film production. Background Technology

[0002] Cover films are typically made of polymer materials such as polyethylene, EVA, and PO. They are usually transparent or semi-transparent sheet materials with a certain degree of flexibility and strength. The production of cover films generally includes steps such as raw material mixing, extrusion blow molding, forming, and winding. During the production process, the cover film usually needs to undergo cooling and drying after extrusion or forming to remove residual moisture and volatiles introduced during processing, ensuring a clean, smooth, and stable film surface.

[0003] Traditional drying processes for covered films often employ heated rollers. Due to the large width and thinness of the covered film, and the presence of transmission steps in the process, uneven heat distribution on the heated rollers is common during drying, resulting in significant differences in dryness between the edges and the center. Furthermore, in some structures, the film may not adhere tightly during transport, leading to low heat transfer efficiency and resulting in localized under-drying or over-drying, thus affecting the overall quality and lifespan of the film. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing covering film drying devices have problems such as uneven drying distribution and uneven drying and wetting of the film surface, making it difficult to achieve efficient and uniform overall drying.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a drying device for the production of covering film, including a frame, a plurality of heat-conducting grooves are opened in the center of the frame, and a detachable combination plate with mesh is provided on the top of the frame. A heating unit is provided at the bottom of the frame, and rectangular frame grooves are fixedly provided on both sides of the frame. A bidirectional push rod motor is fixedly connected to the bottom end of the rectangular frame groove. A connecting arm is fixedly connected to the output end of the bidirectional push rod motor, and a clamping plate is detachably provided at the top of the connecting arm. The clamping plate includes an upper plate and a lower plate, and rubber clamps are fixedly connected to the opposite clamping sides of the upper and lower plates. Telescopic springs are fixedly connected to both sides of the upper and lower plates, and a pair of finger buckles are fixedly connected to the top of the upper plate.

[0006] As a further improvement of this utility model, the heating unit includes a machine compartment fixed below the frame, the machine compartment is equipped with an upward-blowing exhaust fan, and a heating wire plate is provided on the top of the exhaust fan. Several ventilation slots are provided at the top and bottom of the machine compartment.

[0007] As a further improvement of this utility model, the combined plate is configured as a rectangular plate structure, and handles are fixedly provided on both sides. Insertion posts are fixedly connected at the four corners of the bottom of the combined plate, and the insertion posts are reliably inserted into the four corners of the top of the frame.

[0008] As a further improvement of this utility model, horizontally arranged guide strips are fixedly connected to the inner walls of both sides of the rectangular frame groove, and guide grooves matching the guide strips are opened on both sides of the bottom of the connecting arm.

[0009] As a further improvement of this utility model, square grooves for inserting into connecting arms are provided on both sides of the lower plate. A side plate is fixedly connected to the outside of the square groove, and a bolt is threadedly connected to the center of the side plate. Multiple screw holes for screwing into the connecting arm are provided on the outside.

[0010] As a further improvement of this utility model, mounting feet are fixedly connected to the four corners of the bottom of the frame, and two bolts are threadedly connected to the center of the mounting feet.

[0011] The beneficial effects of this utility model are as follows: By setting adjustable clamping plates on the frame, this utility model achieves stable fixation of the covering film, preventing the film from loosening or shifting during operation; the rubber clamps and springs provide appropriate clamping force, ensuring that the film is stable and reliable during fixation without being damaged by excessive pressure.

[0020] This utility model provides a drying device for the production of cover film, including a frame 1;

[0021] As attached Figure 1 , 2 As shown in Figure 4, mounting feet 11 are fixedly connected to the four corners of the bottom of the frame 1, and bolts are threaded to the center of the mounting feet 11; the frame 1 can be fixedly installed on the workbench. Several heat-permeable slots are opened in the center of the frame 1, and a detachable combination plate 2 with mesh holes is set on the top of the frame 1. The mesh hole length is designed to be 3-5mm. The combination plate 2 is set as a rectangular plate structure, and handles are fixedly set on both sides. Insertion posts 8 are fixedly connected to the four corners of the bottom of the combination plate 2, and the insertion posts 8 are reliably inserted into the four corners of the top of the frame 1; by setting the combination plate 2, hot air is concentrated to the bottom of the covering film. A heating unit is set at the bottom of the frame 1. The heating unit includes a machine compartment 7 fixed at the bottom of the frame. The machine compartment 7 has an upward-blowing exhaust fan, and a heating wire plate is set on the top of the exhaust fan, which can continuously output a stable heat flow in the range of 80℃ to 120℃. Several ventilation slots are opened at the top and bottom of the machine compartment 7; to provide heat energy to the bottom of the covering film above.

[0022] As attached Figure 1 , 2 As shown in Figure 4, rectangular frame grooves 3 are fixedly installed on both sides of the frame 1, and a bidirectional push rod motor 4 is fixedly connected to the bottom of the rectangular frame groove 3. A connecting arm 5 is fixedly connected to the output end of the bidirectional push rod motor 4. Horizontally set guide strips are fixedly connected to the inner walls on both sides of the rectangular frame groove 3. Guide grooves 9 matching the guide strips are opened on both sides of the bottom of the connecting arm 5 to ensure sliding guidance between the connecting arm 5 and the guide groove 9. The distance between the connecting arms 5 can be slidably adjusted to adapt to different sizes of covering film.

[0023] As attached Figure 1 , 3 As shown in Figure 4, a clamping plate 6 is detachably mounted on the top of the connecting arm 5; used to fix and clamp the covering film. The clamping plate 6 includes an upper plate 601 and a lower plate 602, and rubber clamping blocks are fixedly connected to the clamping sides of the upper plate 601 and the lower plate 602. Telescopic springs are fixedly connected to both sides of the upper plate 601 and the lower plate 602. The springs are designed to provide elastic restoring force in the range of 3 to 5 N to maintain a tight fit between the two rubber clamping blocks. A pair of finger buckles are fixedly connected to the top of the upper plate 601. Square slots for insertion into the connecting arm 5 are opened on both sides of the lower plate 602. Side plates 10 are fixedly connected to the outside of the square slots, and a bolt is threaded to the center of the side plate 10. Multiple screw holes for screwing the bolt are opened on the outside of the connecting arm 5 to ensure a tight connection with the connecting arm 5.

[0024] Working Principle: In practical implementation, when this device is in use, the connecting arm 5 is first driven by the bidirectional push rod motor 4 to move smoothly horizontally along the rectangular frame groove 3 and the guide groove 9, allowing the connecting arm 5 to adapt to different sizes of covering films. The clamping plate 6 consists of an upper plate 601 and a lower plate 602, both of which have rubber clamping blocks fixed on their clamping surfaces. Under the action of the telescopic spring, a constant clamping force is maintained. The spring is designed to provide elastic restoring force in the range of 3 to 5 N, thereby ensuring that the covering film is not slipped off and avoiding damage to the film material due to excessive pressure. Operators can easily open and close the cover film manually by applying upward force through the finger buckles on the top of the upper plate 601. Once the cover film is securely clamped, the heat exhaust fan in the machine compartment 7 located below the frame 1 starts. Hot air is evenly heated by the heating wire plate, continuously outputting a stable heat flow within the range of 80℃ to 120℃. The hot air is concentrated under the cover film through the combined plate 2 above the frame 1. The combined plate 2 adopts a rectangular plate structure with mesh holes, the mesh length of which is designed to be 3-5mm, which can maintain good air permeability and make the heat flow evenly distributed, avoiding uneven shrinkage of the film due to local overheating. The insertion post 8 at the bottom of the combined plate 2 is reliably fixed to the frame 1, ensuring the overall structural stability during the heating process, thereby ensuring the continuity and safety of the entire sampling and heating process.
