That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1-7As shown, the steel plate coating device includes a frame 1 and a film feed guide roller group 2, a screw nut sleeve position guide adjustment mechanism 3, a film pressing roller group 4 and a straightening roller group 5 which are sequentially mounted on the frame 1. A film unwinding device 6 is also provided above the film pressing roller group 4. A crossbeam 7 with a transverse slide groove is fixedly provided on the frame 1 and below the film unwinding device 6. A support rod is passed through the transverse slide groove. A flying knife 71 which can cut the film when it is facing forward is fixedly provided on the head of the support rod. The tail of the support rod is connected to the movable end of a cylinder 72 fixedly mounted on the frame 1, so that the flying knife 71 can be driven to move left and right by the cylinder 72 to realize the on-demand cutting of the film 8; the screw nut sleeve position guide adjustment mechanism 3 includes a screw rod mounted on the frame 1 31 and a nut sleeve which is sleeved on the screw rod 31 through threaded cooperation. The screw rod 31 is also sleeved with a fixed plate 32 with a perforation in the middle. The left and right ends of the screw rod 31 are respectively provided with a parallel guide rod. An adjustment plate 34 is fixedly provided on the nut sleeve. The fixed plate 32 and the adjustment plate 34 are both penetrated on two parallel guide rods. An adjustment handwheel 35 is provided at one end of the screw rod 31. By rotating the adjustment handwheel 35, the screw rod 31 can be driven to rotate, so that the nut sleeve brings the adjustment plate 34 forward or backward along the screw rod 31 to adjust the distance between the adjustment plate 34 and the fixed plate 32; limiting rollers 33 are provided on the upper left and right sides of the opposite side of the adjustment plate 34 and the fixed plate 32 to prevent the steel plate 9 from jumping.

[0023] The laminating roller group 4 includes a bottom roller 41 located below and a pressing roller 42 located above which cooperate with each other for laminating. The two ends of the bottom roller 41 are respectively mounted on the frame 1 through a fixed block 43, and the two ends of the pressing roller 42 are respectively inserted in a slider 44. The slider 44 can slide up and down along the vertical guide rails 45 arranged on both sides of the fixed block 43. A plurality of buffer springs 46 are also arranged between the fixed block 43 and the slider 44. A limit plate 47 is also fixedly connected to the upper end of the vertical guide rail 45. An adjusting threaded rod 48 is also arranged between the slider 44 and the limit plate 47. The adjusting threaded rod 48 passes through the limit plate 47 and is threadedly matched with the limit plate 47. A hand wheel 49 is arranged on the upper end of the adjusting threaded rod 48. By turning the hand wheel 49, the range in which the pressing roller 42 can move up and down can be expanded or reduced. Then, in cooperation with the buffer spring 46 below, the shaking of the pressing roller 42 during laminating can be well controlled.

[0024] Two buffer springs 46 are further provided between the fixed block 43 and the sliding block 44 .

[0025] The film feed guide roller group 2 includes a plurality of guide rollers 21 arranged in sequence to form an arc shape adapted to the shape of the steel plate 9 just unwound. A limit pressure roller 22 is movably mounted above the guide roller 21 which is closest to the guide adjustment mechanism 3 for the position of the screw nut sleeve, and is limited by vertical support plates arranged on both sides of the guide roller 21. A limit block 23 fixedly connected to the vertical support plate is provided above both ends of the limit pressure roller 22. A second buffer spring 24 is provided between the limit block 23 and the end of the limit pressure roller 22 to guide the steel plate while protecting the steel plate from being scratched when the steel plate is fed.

[0026] The straightening roller set 5 includes a plurality of straightening guide rollers 51 arranged in a staggered manner so as to make better use of the steel plate.

[0027] Working process:

[0028] After the steel plate is unwound from the reel, it enters through the film feed guide roller group whose arc fits with it. When passing through the guide roller 21 located closest to the guide adjustment mechanism 3 of the screw nut sleeve position, the height of the steel plate is controlled to a low position through the cooperation of the roller and the limit pressure roller 22 above it. At the same time, because of the existence of the second buffer spring, the steel plate can be better protected from being scratched; then the steel plate enters the guide adjustment mechanism of the screw nut sleeve position to correct the film feeding position, and then passes through the film pressing roller group to make it film. During this period, the film pressing roller group is also provided with a buffer spring between the bottom roller 41 located below and the pressure roller 42 located above, and the upward jump amplitude of the pressure roller is adjustable, so the stability of the film is ensured; after the film is completed, the steel plate is straightened by the straightening roller group, so that the steel plate is more conducive to the use of the subsequent process. When the film is completed, the flying knife is driven forward by the cylinder to cut the film.

[0029] The steel plate laminating device of the utility model has an ingenious structure. Through the cooperation of the film feeding guide roller group, the screw nut sleeve position guide adjustment mechanism, the film pressing roller group and the straightening roller group, the steel plate can be fed smoothly, prevented from jumping, laminarized smoothly and stably, and straightened into a straight plate. The production is smooth and stable, so that the laminating can be carried out quickly and with high precision. Moreover, through the setting of the flying knife, the cutting of the film can be completed quickly. It is highly practical and worthy of promotion.

[0030] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
