Description

Technical Field

[0001] The invention relates to a pressing and gluing device for whiteboard production, in particular to a multi-point synchronous pressing and gluing device for whiteboard production and an operating method. Background Art

[0002] At present, it is common for enterprises to produce whiteboards. Most of the whiteboards are processed by flat-plate technology for pressing the front panel and the back panel. When producing whiteboards with larger plates, due to the larger area of ​​the whiteboard, the pressure in the middle of the whiteboard is difficult to control. It is common for holes or stratification or two skins to appear in the middle of the whiteboard, and the quality of the finished products is difficult to guarantee. The quality of whiteboards with larger plates affects the reputation of the products. In addition, some whiteboard production panels and back panels are pressed by rolling or pressure-discharging. Due to the uneven pressing area or the staggered layers of the front panel and the back panel, it is common for the finished products to curl and deform. The production quality of larger whiteboards cannot meet the product requirements. In view of the above reasons, a multi-point synchronous pressing and gluing device and an operating method for whiteboard production are proposed. Summary of the invention

[0003] The purpose of the present invention is to overcome the common phenomenon that during the production of larger whiteboards, voids or delamination or two skins appear in the middle of the whiteboard, and the quality of the finished product is difficult to guarantee. In addition, in some whiteboard production, the pressing of the panel and the bottom plate adopts rolling or pressure-discharging type pressing, which is uneven or the panel and the bottom plate are misaligned, resulting in the common phenomenon of curling and deformation of the finished product. Through reasonable design, a multi-point synchronous pressing and gluing device and an operation method for whiteboard production are provided. The multi-point synchronous pressing and gluing device of the present invention can adjust the local pressure in the pressing plate assembly through the pressing plate piston, and the plane of the pressing of the composite whiteboard with a larger surface is balanced, which can avoid the voids or delamination or two skins in the middle of the composite whiteboard. The pressing plate assembly is combined with the adjustment of the pressing plate piston, and the pressing of the whiteboard with a large surface is smooth, without unevenness or misalignment of the panel and the bottom plate, curling and deformation, thereby ensuring the production quality of larger whiteboards, meeting the requirements of the product, and improving the quality and output of the product.

[0012] When the local pressure of the pressing plate is small, the control center opens the corresponding solenoid valve through the local corresponding solenoid valve control module, and starts the hydraulic device pressurization through the hydraulic control module. The hydraulic pressure pushes the pressing plate piston downward to squeeze the local part of the glue-coated composite whiteboard through the local corresponding solenoid valve and cylinder. When the pressure sensing data of the local pressure sensor is the same as the set data, the control center closes the hydraulic device and the local solenoid valve through the hydraulic control module, and stops pressurizing.

[0013] Beneficial effects: The multi-point synchronous pressing and gluing device of the present invention can adjust the local pressure in the pressing plate assembly through the pressing plate piston, so that the plane of the pressing of the composite whiteboard with a larger surface is balanced, and the void or delamination in the middle of the composite whiteboard or the phenomenon of two skins can be avoided; the pressing plate assembly is combined with the adjustment of the pressing plate piston, so the pressing of the whiteboard with a large surface is flat, and there will be no unevenness or misalignment between the panel and the bottom plate, curling and deformation, thereby ensuring the production quality of larger whiteboards, meeting product requirements, and improving product quality and output.

At the same time, when the bottom plate (1-1) passes through the glue coating port of the glue coating device (4-1), the glue coating port evenly coats the top of the bottom plate (1-1) with glue to form a glue coating layer; the bottom of the flexible panel (5-1) is bonded to the bottom plate (1-1) through the glue layer to form a glue-coated composite whiteboard (15-1); the glue-coated composite whiteboard (15-1) enters the composite pressing station (2); after the glue-coated composite whiteboard (15-1) completely covers the top of the movable pressing platform (8), the glue coating pressing wheel mechanism (4) is manually controlled to stop running; After the glue-coating pressing wheel mechanism (4) stops, the control platform (13) is manually started, and the control platform (13) instructs the screw drive control module to start the screw drive device (11) through the control center (13-1), drive the screw (10), and the pressing plate assembly (7) to move downward to extrude the glue-coated composite whiteboard (15-1), and at the same time, the cutting device (7-5) cuts the glue-coated composite whiteboard (15-1); when the control center (13-1) receives pressure data from the pressure sensor (7-4) respectively, and all the pressure data are equal to or greater than the set data, the screw drive control module controls the screw drive device (11) to stop running, and the glue-coated composite whiteboard (15-1) is formed into a finished composite whiteboard (15), and the screw drive control module controls the screw drive device (11) to drive the pressing plate assembly (7) to move upward and separate from the finished composite whiteboard (15), thereby completing the finished product processing of a section of composite whiteboard (15).

3. The method for operating a multi-point synchronous pressing and gluing device for whiteboard production according to claim 2, characterized in that: After the finished product of the composite whiteboard (15) is processed, the lifting wheel wireless control module of the control center (13-1) instructs the wireless control circuit (8-2) to control the lifting wheel 8-1 to drive the mobile pressing platform (8) to move, and the mobile pressing platform (8) drives the finished product of the composite whiteboard (15) to run to the unloading station (3) to stop and unload; the finished product of the composite whiteboard (15) on the mobile pressing platform (8) returns to the composite pressing station (2) after unloading, and the processing of the glue-coated composite whiteboard (15-1) is repeated on the mobile pressing platform (8).

4. The method for operating a multi-point synchronous pressing and gluing device for whiteboard production according to claim 2, characterized in that: During the processing of the glue-coated composite whiteboard (15-1), when the pressure sensing data of the local pressure sensor (7-4) received by the control center (13-1) is less than the set data, it means that the local pressure of the pressing plate master (7) is small; When the local pressure of the pressing plate assembly (7) is low, the control center (13-1) opens the corresponding solenoid valve (7-3) through the local corresponding solenoid valve control module, and at the same time starts the hydraulic device (14) to increase pressure through the hydraulic control module. The hydraulic pressure pushes the pressing plate piston (7-1) downward to squeeze the local part of the glue-coated composite whiteboard (15-1) through the local corresponding solenoid valve (7-3) and the oil cylinder (7-2). When the pressure sensing data of the local pressure sensor (7-4) is the same as the set data, the control center (13-1) closes the hydraulic device (14) and the local solenoid valve (7-3) through the hydraulic control module, and stops pressurizing. The glue-coated composite whiteboard (15-1) is shaped into a finished product of the composite whiteboard (15) through local pressurization, and the processing of a flat finished product of a section of the composite whiteboard (15) is completed; according to the above method, the local pressure of the glue-coated composite whiteboard (15-1) is adjusted, pressed, and shaped, and the finished product processing of the next section of the composite whiteboard (15) is continuously carried out.
