Description

Technical Field

[0001] The utility model relates to the technical field of pre-coated films, and specifically, to an efficient ironing device for pre-coated films. Background Art

[0002] A pre-coated film refers to a process in which a plastic film is pre-coated with glue and then rewound and compounded with a paper print. The pre-coated film consists of a substrate and an adhesive glue layer. When ironing the pre-coated film, since the existing ironing device cannot flatten it evenly, small and numerous wrinkles are often formed, resulting in uneven thickness after coating the pre-coated film and poor product quality.

[0003] The patent specification with the publication number CN211467457U discloses an ironing device for pre-coated films. The pre-coated film is fed through a feeding roller, and the winding roller is wound under the drive of a motor. The pre-coated film is flattened and tensioned by two sets of upper and lower pressing wheels. When the tensioned and flattened pre-coated film passes through the steam plate, the steam output by the steam generator sprays out from the steam holes on the steam plate, so that the steam on both sides irons the two end faces of the pre-coated film, thereby being able to tension and iron the pre-coated film evenly and avoid wrinkles on the pre-coated film.

[0004] However, in the implementation of the related technology, it is found that the above technical solution has the following problems: In the process of using the above device, the pre-coated film is fed through the feeding roller, the winding roller is wound under the drive of the motor, the pre-coated film is flattened and tensioned by two sets of upper and lower pressing wheels, and when the tensioned and flattened pre-coated film passes through the steam plate, the steam output by the steam generator sprays out from the steam holes on the steam plate, so that the steam on both sides irons the two end faces of the pre-coated film. However, when the pre-coated film needs to be placed on the feeding roller, the staff needs to climb to a high place to place the pre-coated film, and the operation process is relatively inconvenient, and there are certain safety hazards in high-altitude operations. Therefore, further improvement is needed. Content of the Utility Model

[0005] The utility model provides an efficient ironing device for pre-coated films, which solves the problem in the related technology that it is not convenient to iron the pre-coated film.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] In this utility model, the pre-coated film is coiled around the unwinding roller. Then, one side of the pre-coated film passes through the space between the first rotating rod and the second rotating rod, and then through the space between the upper steam plate and the lower steam plate. This side of the pre-coated film is coiled around the outer surface of the winding roller.

At this time, the coiling of the pre-coated film around the outer surface of the unwinding roller disappears and it is coiled onto the outer surface of the winding roller. As the pre-coated film moves, it first passes through the first rotating rod and the second rotating rod. At this time, the first rotating rod and the second rotating rod are driven by the movement of the pre-coated film to rotate. At this time, under the action of the two groups of smoothing pads, the wrinkled pre-coated film can be initially smoothed. Then, the first telescopic rod and the second telescopic rod are controlled to extend and retract, pushing the upper steam plate and the lower steam plate closer to the pre-coated film, so that the upper steam plate and the lower steam plate are respectively attached to the upper and lower ends of the pre-coated film. Then, the steam holes are controlled to eject steam onto the pre-coated film. As the pre-coated film moves along the lower end of the upper steam plate and the upper end of the lower steam plate, the pre-coated film is effectively ironed, solving the problem of being inconvenient to iron the pre-coated film.

The ironing assembly 2 includes a first vertical plate 21 and a second vertical plate 22 disposed at the central positions between the feeding roller 1 and the winding roller 3. The structures of the first vertical plate 21 and the second vertical plate 22 are symmetrical. One side of the first vertical plate 21 and the second vertical plate 22 is rotatably connected with a first rotating rod 23 and a second rotating rod 24. The structures of the first rotating rod 23 and the second rotating rod 24 are the same. The first rotating rod 23 is located directly above the second rotating rod 24. An upper steam plate 25 and a lower steam plate 26 are slidably connected between the first vertical plate 21 and the second vertical plate 22. The upper steam plate 25 is located above the lower steam plate 26.

[0024] As Figure 1 shown, both ends of the first rotating rod 23 are fixedly connected with rotating shafts 232. The outer surface of the first rotating rod 23 is evenly fixedly connected with smoothing pads 231. The rotating shafts 232 are rotatably connected inside the first rotating grooves 2131. The presence of the first rotating rod 23 facilitates the first rotating rod 23 to rotate along the first rotating grooves 2131. The upper and lower groups of smoothing pads 231 are used to smooth the wrinkles of the pre-coated film.

[0025] As Figure 2 shown, a first T-shaped groove 211 and a second T-shaped groove 212 are formed at the central position on one side of the first vertical plate 21. A side of the first vertical plate 21 is fixedly connected with an auxiliary block 213. A first rotating groove 2131 and a second rotating groove 2132 are formed on one side of the auxiliary block 213. The auxiliary block 213 is close to the feeding roller 1. The first rotating groove 2131 is located above the second rotating groove 2132. The first rotating groove 2131 is used to place the rotating shafts 232 of the first rotating rod 23, and the second rotating groove 2132 is used to place the rotating shafts 232 of the second rotating rod 24. The first T-shaped groove 211 and the second T-shaped groove 212 are used to separate the upper steam plate 25 and the lower steam plate 26 so that the two will not collide with each other.

[0026] As Figure 3As shown, both sides of the upper steam plate 25 are fixedly connected with first T-shaped blocks 251. The upper ends of the first T-shaped blocks 251 are fixedly connected with first telescopic rods 252. The first T-shaped blocks 251 are slidably connected with first T-shaped grooves 211. The upper ends of the first telescopic rods 252 are fixedly connected with the inner walls of the first T-shaped grooves 211. Both sides of the lower steam plate 26 are fixedly connected with second T-shaped blocks 261. The lower ends of the second T-shaped blocks 261 are fixedly connected with second telescopic rods 262. Steam holes 263 are fixedly formed in the upper ends of the lower steam plate 26 and the lower ends of the upper steam plate 25. The second T-shaped blocks 261 are slidably connected with second T-shaped grooves 212. The upper ends of the second telescopic rods 262 are fixedly connected with the inner walls of the second T-shaped grooves 212. The steam holes 263 are used for steam spraying and ironing the pre-coated film. The upper steam plate 25 is used for steam spraying and ironing the upper layer of the pre-coated film. The lower steam plate 26 is used for steam spraying and ironing the lower layer of the pre-coated film.

[0027] The working principle and usage instructions of the present utility model are as follows: When it is necessary to iron the pre-coated film, first, the staff needs to take out the pre-coated film. Then, the staff needs to wind the pre-coated film around the unwinding roller 1. Next, one side of the pre-coated film passes through between the first rotating rod 23 and the second rotating rod 24, and then passes through between the upper steam plate 25 and the lower steam plate 26, and winds the pre-coated film on the outer surface of the winding roller 3. Then, start the winding roller 3 to drive the pre-coated film to wind around the outer surface of the winding roller 3. At this time, the winding of the pre-coated film on the outer surface of the unwinding roller 1 disappears and winds onto the outer surface of the winding roller 3. As the pre-coated film moves, it will first pass through the first rotating rod 23 and the second rotating rod 24. At this time, the first rotating rod 23 and the second rotating rod 24 are driven to rotate by the movement of the pre-coated film. At this time, under the action of the two groups of smoothing pads 231, the wrinkled pre-coated film can be initially smoothed. Then, control the first telescopic rod 252 and the second telescopic rod 262 to expand and contract, pushing the upper steam plate 25 and the lower steam plate 26 towards the pre-coated film, so that the upper steam plate 25 and the lower steam plate 26 are respectively attached to the upper and lower ends of the pre-coated film. Then, control the steam holes 263 to spray steam on the pre-coated film. As the pre-coated film moves along the lower end of the upper steam plate 25 and the upper end of the lower steam plate 26, effective ironing of the pre-coated film is achieved.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model.
