Description

Technical Field

[0001] The utility model relates to the technical field of plate processing equipment, in particular to a film coating device for the surface of a plate. Background Art

[0002] After production, the surface of the sheet metal needs to be laminated to prevent surface damage during transportation due to friction and collision, which could lead to unnecessary losses. During lamination, rollers are usually used to press the laminating material onto the sheet metal to improve the fit between the laminating material and the sheet metal, making the laminating material adhere more tightly.

[0003] However, when processing some curved plates, rollers cannot be used. It is necessary to manually apply pressure to the coating or customize rolling objects corresponding to the surface of the plate, which is time-consuming and labor-intensive. Alternatively, the plate can be coated and then processed into an arc. However, during the arc processing process, the surface of the coating material is easily damaged by stretching or scratching.

[0004] For this reason, we propose to design a film coating device for the surface of the plate. Utility Model Content

[0024] See also Figure 1-3 The utility model provides a film coating device for a plate surface, comprising a base 1, a linear motor 2 is embedded and fixedly connected inside one side of the top of the base 1, and a gantry 3 is fixedly connected to the top of the driving end of the linear motor 2.

[0025] A slide groove 4 corresponding to the gantry 3 is provided on the side of the top of the base 1 away from the linear motor 2, and a guide rod 5 is fixedly connected between the two sides of the inner wall of the slide groove 4. The guide rod 5 passes through one end of the gantry 3 and is slidably connected to it, so that the linear motor 2 can drive the gantry 3 to move back and forth on the top of the base 1.

[0026] An electric push rod 7 is fixedly connected to the center of the top of the gantry 3. The telescopic end of the electric push rod 7 passes through the gantry 3 and is provided with a film pressing mechanism 8.

[0027] The film pressing mechanism 8 includes an equipment frame 9 fixedly connected to the telescopic end of the electric push rod 7, and a drive motor 10 is fixedly connected to one side of the outer wall of the equipment frame 9. The drive shaft of the drive motor 10 passes through the equipment frame 9 and is fixedly connected to a fixed frame 11, and a roller 12 is arranged inside the fixed frame 11.

[0028] The two ends of the roller 12 are respectively connected to the bearings on both sides of the inner wall of the fixing frame 11, and the outer wall of the roller 12 is sleeved with a rubber ring, which facilitates full contact with the plate to improve the lamination effect when laminating and pressing the horizontal plate.

[0029] An air chamber 13 is embedded in the middle of the fixing frame 11 and fixedly connected. An air pipe 14 is fixedly connected to one side of the air chamber 13 near the center of the base 1. A pulse air valve 15 is fixedly connected to the connection between the air pipe 14 and the air chamber 13.

[0030] In this embodiment, a plurality of air pipes 14 are provided, and the plurality of air pipes 14 are evenly distributed on the outer wall of the air bin 13 and are arranged vertically to the outer wall of the air bin 13. When the fixed frame 11 is rotated, it is convenient to switch between roller 12 pressurization and pneumatic pressurization to adapt to the processing conditions of different plates.

[0031] An air nozzle 16 is provided at the exhaust end of the air pipe 14, and an input pipe 17 is fixedly connected to the side of the fixed frame 11 away from the drive motor 10. One end of the input pipe 17 is connected to the inside of the air bin 13, and the other end is connected to the exhaust end of the external air pump. The air is supplied by the external air pump, injected into the air bin 13 through the input pipe 17, and finally ejected through the air nozzle 16, which is convenient for pressurizing the surface of the plate to make the coating and the plate fit better.

[0032] Among them, limit bars 6 are provided near the center on both sides of the top of the base 1. The limit bars 6 are fixed to the top of the base 1 by bolts. The area between the two limit bars 6 corresponds to the jet range of the air nozzle 16. The entry position of the plate is restricted by the limit bars 6, so that it can be pressurized by the air nozzle 16 when moving at the top of the base 1.

[0033] When in use, first connect the linear motor 2, the electric push rod 7, the drive motor 10 and the pulse air valve 15 to the external power supply, and connect the input pipe 17 to the external air pump.

[0034] Place the newly coated sheet on top of the base 1, and select the corresponding coating pressurization method according to the type of sheet. If it is a flat sheet, the electric push rod 7 drives the equipment frame 9 to descend, so that the roller 12 contacts the sheet surface and presses it on the coating material. Then start the linear motor 2 to drive the gantry 3 and the roller 12 at its bottom to move back and forth on the top of the base 1, so that the coating material can be fully adhered to the surface of the sheet.

[0035] For curved sheet materials, the drive motor 10 is activated to rotate the mounting bracket 11, causing the originally parallel air tubes 14 to point vertically downward. The external air pump is then activated to sequentially open the pulse air valves 15 corresponding to the air tubes 14, releasing high-pressure air through the air nozzles 16. Note that the order in which the air valves are opened must be carefully considered. For example, for a curved sheet material in this embodiment, the pulse air valves 15 are opened sequentially from the center toward the sides, ensuring that the coating material adheres fully to the sheet material surface.

[0036] In this device, the coordinated work between the linear motor 2, the electric push rod 7, the drive motor 10 and the pulse air valve 15, as well as the opening and closing of each pulse air valve 15, can all be achieved through external PLC programming. This is existing technology and will not be described in detail here.

In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
