Description

Technical Field

[0002] The film laminating device is an essential processing equipment for special sheet metal requirements during the shearing process, such as stainless steel and aluminum sheets, to ensure that the sheet surface will not be scratched or damaged during the subsequent production process, which would affect its product quality. Currently, most slitting and shearing equipment uses a single film laminating device. During the slitting operation, only one size or type of film roll can be applied at a time. If multiple sizes of rolls are produced simultaneously during the slitting operation, or if multiple customers have different requirements for film laminating operations, a single operation cannot meet the requirements of multiple varieties or film sizes. Each specification must be re-rolled and laminating separately, resulting in low production line efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 、2 As shown in Figure 3, an efficient three-film laminating device in this embodiment includes a horizontally arranged bracket 2, with both ends of the bracket 2 mounted on the frame. Three rotating seats are provided at one end of the bracket 2: the first rotating seat 1, the second rotating seat 24 and the third rotating seat 4, and three fixed seats are provided at the other end of the bracket 2: the first fixed seat 21, the second fixed seat 23 and the third fixed seat 22. Slides 15 are provided on the fixed seats respectively, and the slides 15 correspond to the rotating seats. Tensioning shafts 13 are respectively arranged between the slides 15 and the corresponding rotating seats, and rolls of film of different sizes are respectively sleeved on the tensioning shafts 13. Bearing seats 9 are respectively provided on the first rotating seat 1, the second rotating seat 24 and the third rotating seat 4, and corresponding bearing seats 9 are respectively passed through one end of the tensioning shafts 13. The first rotating seat 1 and the second rotating seat 24 are symmetrically arranged on the front and back sides of the bracket 2, and the third rotating seat 4 is arranged on the top surface of the bracket 2. The first, second, and third rotating bases 1, 24, and 4 are each connected to the bracket 2 via vertically arranged pins, allowing them to swing back and forth about the pins, facilitating the loading of the film roll onto the tensioning shaft. The other ends of the tensioning shafts are housed within corresponding slides 15. A moving mechanism drives the slides 15 left and right along their corresponding fixed bases, driving the tensioning shafts left and right. This not only corrects the film roll's position but also facilitates the removal of the tensioning shafts from the bearing housing.

[0018] The above-mentioned moving devices each include a horizontally arranged rotating shaft 12, on which a guide roller 11 is mounted. The guide roller 11 guides the film released from the tensioning shaft. Three supports are respectively provided on the frame: a first support 7, a second support 5, and a third support 3, which correspond to the rotating seat. One end of the rotating shaft 12 is penetrated by a corresponding support and fixed to the support via a flange 10. A rocker 8 is provided at one end of the rotating shaft 12, and the other end of the rotating shaft 12 is fixedly connected to a screw 17 via a coupling 14. A guide slide 16 is mounted on the screw 17, which is threadedly connected to the screw 17. A fixed seat is mounted on the top of the guide slide 16 and fixed to the bottom of the slide 15. When the rocker 8 rotates, it drives the rotating shaft 12 and the screw 17 to rotate synchronously, causing the guide slide to move left and right along the screw, thereby realizing left and right movement of the slide and the tensioning shaft. In order to adjust the film laminating operation, when the film released from the roll is not in the center of the steel plate of the laminating operation, that is, when the film is offset, the rocker is manually rotated to correct the position of the film roll.

[0019] The above-mentioned rotating seat is respectively hinged with one end of the limit rod 6, and the other end of the limit rod 6 is a free end. A limit block is respectively set on the support, and the limit rod can swing up and down around the hinge point. When the limit rod is clamped in the limit block, the swing of the rotating seat is restricted.

[0020] The top surface of the fixed seat is symmetrically provided with slide rails 20, and the bottom of the slide seat 15 is clamped on the slide rails 20. After the slide seat moves into place, the slide seat is fixedly connected with the fixed seat by the symmetrically arranged pressure strips 19.

[0021] A magnetic powder brake 18 is provided at the end of the tensioning shaft 13, and the magnetic powder brake is used to adjust the unwinding tension of the film roll.

[0022] Three tensioning shafts can simultaneously prepare three film rolls, with the type, size, and specifications of the three rolls determined based on actual needs. During the coil slitting process, film can be applied simultaneously to meet the requirements of the finished product, with all film sizes and specifications being available during the same slitting operation. This application is convenient and tailored to the customer's actual film application needs, reducing repetitive work and improving production efficiency.

[0023] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
