Description

Technical Field

[0001] This utility model relates to the field of composite product manufacturing technology, specifically to an automatic furnace exit and curing chamber braking device. Background Technology

[0002] In the production of composite products, the curing chamber is a crucial step in processes such as flexible packaging lamination, requiring extremely high control over the curing time. Traditional curing chambers require manual removal of the film rolls, which often results in the film being left uncured beyond the specified curing time or being removed prematurely, easily leading to product process problems and quality risks.

[0003] While existing automatic door devices in automated curing chambers can reduce manual intervention, some devices suffer from insufficient precision in electric braking, poor synchronization of door opening and closing, and a lack of emergency braking mechanism. When the electric braking unit fails, the door cannot open or close in time, affecting not only the efficiency of film unloading from the oven but also causing significant heat loss from the curing chamber, further impacting product curing quality. Therefore, a curing chamber braking device is needed that combines precise electric braking, reliable manual emergency braking, and efficient synchronous opening and closing. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an automatic unloading and maturation chamber braking device, which solves the problems of quality risks associated with manual operation of traditional maturation chambers, poor synchronization of automatic door electric braking, and lack of emergency braking mechanism.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic unloading curing chamber braking device, comprising an electric braking unit installed on the front of the curing chamber door frame. The electric braking unit includes a brake servo motor, two fixed blocks, and a transmission rod. The transmission rod is rotatably mounted on the two fixed blocks. A rotating rod is inserted into the interior of each fixed block. A door leaf is fixedly sleeved on the outer side of the rotating rod. Both ends of the transmission rod extend into the interior of the two fixed blocks and are fixedly connected to worm gears. A worm wheel that meshes with the worm gear is fixedly sleeved on the outer side of the end of the rotating rod. A manual braking unit for braking the rotating rod is provided on the outer side of each fixed block.

[0006] Preferably, a gear is fixedly connected between the end of the worm gear near the brake servo motor and the end of the brake servo motor, and the two gears are meshed together.

[0007] Preferably, the end of the rotating rod extends outward through the fixing block, and the end of the rotating rod facing outward has multiple limiting holes.

[0008] Preferably, the multiple limiting holes are arranged in a circumferential array.

[0009] Preferably, the manual braking unit includes a fixed cylinder and a brake rod. The fixed cylinder is fixedly connected to the side of the fixed block, and the brake rod is movably inserted into the fixed cylinder. The end of the brake rod extends toward the limiting hole, and a limiting block adapted to the limiting hole is fixedly installed at the end of the brake rod.

[0010] Preferably, a U-shaped groove is provided on the outer side of the fixed cylinder, and an operating rod is fixedly installed on the outer side of the brake rod, with the end of the operating rod extending outward through the U-shaped groove.

[0011] Preferably, two electric braking units are provided.

[0013] Its beneficial effects are as follows: 1. The automatic unloading curing chamber braking device has an electric braking unit in which a braking servo motor drives a transmission rod through gear transmission. Combined with the meshing structure of worm and worm wheel, it can accurately drive the rotating rod to open and close the door. Moreover, the two electric braking units correspond to the two door openings, ensuring that the door moves synchronously and avoiding jamming or delay caused by asynchronous opening and closing when the film roll is unloaded.

[0014] 2. The automatic unloading curing chamber braking device has a manual braking unit that works with the limit hole of the brake rod, limit block and rotating rod. When the electric braking unit fails, the door can be quickly fixed to avoid heat loss in the curing chamber or abnormal film unloading due to equipment failure. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] This utility model discloses an automatic unloading and maturation chamber braking device, according to the attached... Figure 1 -Appendix Figure 5 As shown, it includes an electric braking unit 1, which is installed on the front of the door frame of the curing room. The electric braking unit 1 includes a brake servo motor 11, two fixed blocks 12, and a transmission rod 13. The transmission rod 13 is rotatably mounted on the two fixed blocks 12. A rotating rod 3 is inserted into the inside of the fixed blocks 12. A door leaf 4 is fixedly sleeved on the outside of the rotating rod 3. Both ends of the transmission rod 13 extend into the inside of the two fixed blocks 12 and are fixedly connected to worm gears 14. A worm wheel 15 that meshes with the worm gear 14 is fixedly sleeved on the outside of the end of the rotating rod 3. A manual braking unit 2 for braking the rotating rod 3 is provided on the outside of the fixed blocks 12.

[0021] In the electric braking unit 1, the brake servo motor 11 drives the transmission rod 13 through gear transmission. Combined with the meshing structure of the worm gear 14 and the worm wheel 15, it can accurately drive the rotating rod 3 to open and close the door leaf 4. The two electric braking units 1 correspond to the two door openings, ensuring that the door leaf 4 moves synchronously and avoiding jamming or delay caused by asynchronous opening and closing when the film roll comes out of the oven.

[0022] According to the appendix Figure 5 As shown, furthermore, gears are fixedly connected between the end of the worm gear 14 near the brake servo motor 11 and the end of the brake servo motor 11, and the two gears are meshed together.

[0023] According to the appendixFigure 4 As shown, further, the end of the rotating rod 3 extends outward through the fixing block 12, and the end of the rotating rod 3 located on the outside is provided with multiple limiting holes 31, and the multiple limiting holes 31 are arranged in a circumferential array.

[0024] According to the appendix Figure 6 As shown, the manual braking unit 2 further includes a fixed cylinder 21 and a brake lever 22. The fixed cylinder 21 is fixedly connected to the side of the fixed block 12, and the brake lever 22 is movably inserted into the fixed cylinder 21. The end of the brake lever 22 extends toward the limiting hole 31, and a limiting block 23 that matches the limiting hole 31 is fixedly installed at the end of the brake lever 22.

[0025] A U-shaped groove 24 is provided on the outer side of the fixed cylinder 21, and an operating rod 25 is fixedly installed on the outer side of the brake rod 22, with the end of the operating rod 25 extending outward through the U-shaped groove 24.

[0026] The manual braking unit 2, through the brake lever 22, the limiting block 23 and the limiting hole 31 of the rotating rod 3, can quickly fix the door leaf 4 when the electric braking unit 1 fails, so as to avoid heat loss in the curing chamber or abnormal film rolling out of the oven due to equipment failure.

[0027] According to the appendix Figure 1 As shown, there are two electric braking units 1, and the door frame of the curing room has two door openings, with the two electric braking units 1 located on the front of the two door openings respectively.

[0028] When the film roll is ready to exit the oven, the brake servo motor 11 starts, and its end gear meshes with the end gear of the transmission rod 13, driving the transmission rod 13 to rotate within the two fixed blocks 12; the worm gears 14 at both ends of the transmission rod 13 rotate synchronously and mesh with the worm wheel 15 at the end of the rotating rod 3, driving the rotating rod 3 to rotate, thereby driving the door 4 fixed on the outside of the rotating rod 3 to open; after the film roll exits the oven, the brake servo motor 11 rotates in the opposite direction, driving the door 4 to close through the above transmission structure.

[0029] When it is necessary to manually fix the door leaf 4, the brake rod 22 is moved along the U-shaped groove 24 of the fixing cylinder 21 by the operating rod 25, so that the limiting block 23 at the end of the brake rod 22 is inserted into the limiting hole 31 of the rotating rod 3, which can restrict the rotation of the rotating rod 3 and realize the braking of the door leaf 4; when the brake is released, the operating rod 25 is moved in the opposite direction to make the limiting block 23 disengage from the limiting hole 31.
