Description

Technical Field

[0001] The utility model belongs to the technical field of decorative film production, and in particular relates to a PVC decorative film pressing device. Background Art

[0002] PVC decorative film is a material used for home decoration, usually used to cover furniture surfaces, walls or other decorative purposes. It is made of polyvinyl chloride (PVC) material and has the characteristics of flexibility, durability and easy cleaning.

[0003] When covering the surface of furniture with PVC decorative film, a PVC decorative film pressing device is required. Usually, the board for making furniture is transported to the bottom of the hot pressing plate, and then the PVC decorative film is covered on the top of the board. The hot pressing plate is pressed down and heated to fix the PVC decorative film on the surface of the board.

[0004] However, the existing PVC decorative film pressing device is prone to plate displacement during pressing and transporting the plate, resulting in the PVC decorative film and the plate not being well attached or the texture of the PVC decorative film being tilted relative to the plate, affecting the appearance. Utility Model Content

[0005] The purpose of the utility model is to solve the problem of the current PVC decorative film pressing device described in the above background technology that the current PVC decorative film pressing device will deviate when pressing or transporting the plate. A new PVC decorative film pressing device is proposed, which can reduce the deviation when transporting the plate and can fix the plate well during pressing.

[0006] A technical solution adopted to achieve the above-mentioned purpose is a PVC decorative film laminating device, which comprises a workbench, a support frame, a feed roller, a transmission unit, a laminating unit, a fixing unit and a loading platform, wherein the interior of the workbench is hollow and the top is open, the support frame is fixed on the top of the workbench, and the top of the workbench is rotatably connected to the feed roller; the transmission unit comprises a transmission belt and a motor, and the transmission belt is connected to the motor through a belt; the laminating unit comprises a hydraulic pump, a hydraulic rod and a pressing plate, the hydraulic rod connects the hydraulic pump and the pressing plate, the hydraulic pump is arranged above the support frame, and the hydraulic rod passes through the top plate of the support frame; the fixing unit comprises an exhaust fan, a main line, a plurality of branch lines and a plurality of wind hoods, the main line is connected to the exhaust fan, one end of the branch line is connected to the main line, and the other end of the branch line is fixedly connected to the wind hood; a plurality of hollow parts are arranged at intervals at the bottom of the loading platform.

[0007] In the above technical solution, the sheet is transferred to the bottom of the pressing unit through the transmission unit. During transportation, the sheet is fixed on the loading platform for transportation to reduce vibration during transportation and prevent the sheet from shifting. The pressing plate is pressed down by the hydraulic pump to make the PVC decorative film adhere to the sheet. During pressing, the vacuum pump is started to form negative pressure under the sheet, thereby fixing the sheet.

[0008] Furthermore, the conveyor belt includes a plurality of conveyor rollers, the conveyor rollers are connected by chains, two ends of the conveyor rollers are rotatably connected to the inner walls of both sides of the workbench, and the conveyor rollers are arranged at intervals.

[0009] In the above technical solution, a gap is left between each pair of the transmission rollers, and the gap provides an installation space for the fixing unit.

[0010] Furthermore, the branch pipeline passes through the gap between the transmission rollers, and the top of the wind cover is flush with the apex of the transmission roller.

[0011] In the above technical solution, this arrangement enables the top of the wind hood to contact the loading platform, and can more easily form negative pressure on the top of the loading platform.

[0012] Furthermore, the hollow portion is smaller than or equal to the opening size of the wind shield.

[0013] In the above technical solution, this arrangement enables the wind shield to completely cover the hollow portion, so that negative pressure is formed between the plate and the wind shield, thereby achieving fixation of the plate.

[0014] Furthermore, the spacing distance between two of the wind shields is equal to the spacing distance between two of the hollow parts.

[0015] In the above technical solution, the same intervals are set so that the positions of the wind shields and the hollow parts correspond to each other, thereby enhancing the adsorption effect.

[0016] Furthermore, a laser emitting device is provided on the outer side wall of the stage, and a laser receiving device is provided on the support frame.

[0017] Furthermore, the PVC decorative film laminating device also includes a control unit, which includes an input unit and an output unit, wherein the input unit is electrically connected to the laser receiving device, and the output unit is electrically connected to the vacuum pump and the motor.

[0018] In the above technical solution, the laser emitting device and the laser receiving device correspond to each other. When the laser receiving device receives the laser signal, it is transmitted to the input unit. The input unit receives the signal, thereby controlling the motor to stop working through the output unit, moving the stage to the corresponding position, starting the vacuum pump, and fixing the plate on the stage.

[0019] Furthermore, a heating wire is provided inside the pressing plate.

[0020] In the above technical solution, the movement of the limiting plate is achieved by the first connecting rod and the second connecting rod, so that the distance of the limiting plate is adjusted to limit the plate on the loading platform.

[0021] The advantages of the utility model are:

[0022] 1. The utility model adds a loading platform to transport the plates, which is more stable than directly transporting the plates and is less likely to cause deviation during transportation.

[0023] 2. The utility model adds a fixing unit, which forms a negative pressure between the plate and the wind hood through the exhaust fan, so that the plate is fixed and prevented from shifting. BRIEF DESCRIPTION OF THE DRAWINGS
