Abstract

The present invention discloses a double-sided molding device for formaldehyde-free environmentally friendly antibacterial plates, belonging to the technical field of double-sided molding of plates. It includes a frame device for winding the film. A placing device and a film pressing device are arranged on the frame device. The placing device is used for applying glue to the plates and pre-pressing them with the film, and the film pressing device is used for pressing the film onto both sides of the plates. The placing device provided by the present invention first applies glue to the plates to be molded, thereby strengthening the bonding effect between the upper and lower surfaces of the plates and the film. At the same time, two pre-pressing mechanisms are used to pre-press the plates and the film, improving the quality of subsequent double-sided molding of the plates. The winding of the film drives the plates to move together. Subsequently, the film on both sides of the plates is hot-pressed onto the plates through the film pressing device, with high automation and good continuity. When the pressing block rises, it will lift one end of the lifting rod, causing the molded plates to slide onto the plate slope, realizing automatic discharging.

Description

Technical Field

[0001] The present invention relates to the technical field of double-sided die pressing of plates, and particularly relates to a double-sided die pressing device for formaldehyde-free environmentally friendly antibacterial plates. Background Art

[0002] Formaldehyde-free environmentally friendly antibacterial plates are a type of new materials that have attracted much attention in recent years in the fields of home decoration, furniture production, etc. These plates not only focus on environmental protection but also have antibacterial functions, which can effectively reduce harmful substances in the air and inhibit the growth of bacteria. These plates usually contain no or very little formaldehyde, benzene and other harmful substances. Formaldehyde is one of the toxic gases released by common building materials and has potential hazards to human health. Formaldehyde-free plates reduce the release of formaldehyde by using formaldehyde-free adhesives or other environmentally friendly materials. Formaldehyde-free plates are added with natural minerals, antibacterial additives or adopt antibacterial coating technology, so that their surfaces can effectively inhibit the growth of bacteria and molds. These plates can usually resist common bacteria and fungi, avoid the spread of bacteria, and improve the sanitary conditions of living and working environments. Double-sided die pressing of plates is a common processing technology, mainly used for plate surface treatment, especially in industries such as furniture manufacturing, decorative materials and building materials. Through the double-sided die pressing process, the aesthetics, durability and adaptability of the plates can be effectively improved. The plate and covering materials, such as decorative paper, PVC film, wood veneer, etc. are placed in the mold, and under the action of high temperature and high pressure, through die pressing forming, the surface decorative layer is firmly bonded to the substrate; although the double-sided die pressing device for plates in the prior art can perform double-sided die pressing on the plates, it usually directly performs die pressing and cannot perform gluing and pre-pressing operations, resulting in poor quality of plate die pressing, and at the same time, it cannot perform full-automatic processing and has low automation.

[0009] The motor rotates to drive the motor gear to rotate, thereby driving the upper gear, the camshaft and the cam to rotate. Through the meshing of every two upper gears with each other, all cams are driven to rotate synchronously. The cam drives the pressing block to continuously rise and fall. The rightmost camshaft drives the upper winding drive belt and the winding wheel to rotate through the drive belt. The lower winding drive belt and the winding wheel are driven to rotate synchronously through the intermediate drive belt. The winding roller is driven to rotate through the winding drive belt. The film is wound by the rotation of the two winding rollers.

[0010] Furthermore, the placing device further includes a placing inner rod rotatably installed on the placing frame. A placing outer rod is rotatably installed on the main frame. A spring is arranged between the placing inner rod and the placing outer rod.

[0011] Furthermore, the glue coating mechanism includes two glue rods rotatably installed on the main frame. A glue coating roller is rotatably installed on the glue rod. Glue is contained in the glue coating roller. A glue coating inner rod is rotatably installed on the upper glue rod. A glue coating outer rod is rotatably installed on the lower glue rod. A spring is arranged between the glue coating outer rod and the glue coating inner rod.

[0012] Furthermore, the pre-pressing mechanism includes two pre-pressing rods rotatably installed on the main frame. A pre-pressing roller is rotatably installed on the pre-pressing rod. A pre-pressing inner rod is rotatably installed on the pre-pressing rod. A pre-pressing outer rod is rotatably installed on the main frame. A spring is arranged between the pre-pressing outer rod and the pre-pressing inner rod.

[0013] Wind two rolls of film around the upper and lower film roll cylinders respectively. Manually pull out the film. The film does not pass through between the glue - applying rollers but passes outside the glue - applying rollers. Subsequently, the film passes through between two groups of pre - pressing rollers. Then, the end of the upper film is fixed on the upper winding roller, and the end of the lower film is fixed on the lower winding roller.

[0014] First, insert the board between two glue - applying rollers. Brush glue on the upper and lower surfaces of the board through the glue - applying rollers. Subsequently, the glued board reaches between the first group of pre - pressing rollers and adheres to the upper and lower layers of film. Pre - press the board and the film through two groups of pre - pressing rollers. Drive the film to wind by rotating the winding roller. Drive the board to move forward together by the force of the film winding. Then, the board and the film reach between the pressing block and the lower pressing block.

[0015] Further, the film - pressing device further includes a compression spring arranged between the outer cylinder and the inner spring column. A breaking groove is arranged in the lower pressing block. The board is conveyed into the breaking groove. A cutter is arranged on the edge of the breaking groove for cutting the film on the board. A positioning groove is arranged on the lower surface of the pressing block, and there are round corners around the positioning groove for positioning the board.

[0016] Further, a lower pressing frame is fixedly installed on the pressing block. A lifting slider is slidably installed on the lower pressing frame. A lifting rod is fixedly installed on the rotating - out plate. A spring column is fixedly installed on the bottom plate. A tension spring is arranged between the spring column and the lifting rod. A slope is arranged on the lower surface of the lifting slider.

[0017] The board and the film on its upper and lower surfaces are conveyed together under the pressing block. The pressing block descends and cooperates with the lower pressing block. At the same time, the pressing block and the lower pressing block are heated to press - fit the board and the film on its upper and lower surfaces. At the same time, the part where the film adheres to the board is cut off by the cutter on the edge of the breaking groove. The un - cut part continues to be wound. And the width of the film roll is greater than the width of the board, so the film will not be cut off. When the pressing block descends, it will drive the lower pressing frame to descend, thereby driving the lifting slider to descend. When the lifting slider contacts the lifting rod, since the lifting rod cannot descend, the lifting rod pushes the lifting slider to slide along the lower pressing frame through the slope of the lifting slider. Then, after the lifting slider passes the lifting rod, the lifting slider slides back along the lower pressing frame under the action of gravity. At this time, the lifting slider is located below the lifting rod. Then, when the pressing block descends to the lowest point, the cam continues to rotate, the compression spring rebounds, the outer cylinder and the pressing block rise, thereby driving the lower pressing frame and the lifting slider to rise. The lifting slider drives the lifting rod to rise, thereby driving the rotating - out plate to rotate relative to the lower pressing block. The tension spring is stretched. The board with the upper and lower films pasted is lifted by the rotating - out plate. Then, the board slides along the inclined rotating - out plate to the discharging slope for discharging. Since the lifting rod and the rotating - out plate rotate around the lower pressing block, when the lifting slider lifts the lifting rod to a certain height, the lifting rod will disengage from the lifting slider. Then, the tension spring rebounds, causing the lifting rod and the rotating - out plate to reset, and the rotating - out plate returns to the initial position.

[0018] The beneficial effects of the present invention compared with the prior art are as follows: (1) The placement device provided in the present invention first applies glue to the plates to be molded, thereby strengthening the bonding effect between the upper and lower surfaces of the plates and the film. At the same time, two pre-pressing mechanisms are used to pre-press the plates and the film, improving the quality of subsequent double-sided molding of the plates; (2) The winding mechanism provided in the present invention can wind the films on the upper and lower surfaces of the plates. After the plates are coated and pre-pressed with the films, the films are wound to drive the plates to move together. Subsequently, the films on both sides of the plates are hot-pressed onto the plates by the film pressing device, with high automation and good continuity; (3) When the pressing block descends in the present invention, it will not drive the lifting rod to move. When the pressing block ascends, it will lift one end of the lifting rod, causing the molded plates to slide onto the plate slope, realizing automatic discharging. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] As Figure 3As shown in the figure, the gluing mechanism includes two glue rods 205 rotatably mounted on the main frame 101. A gluing roller 206 is rotatably mounted on the glue rod 205. Glue is contained inside the gluing roller 206. A gluing inner rod 208 is rotatably mounted on the upper glue rod 205, and a gluing outer rod 207 is rotatably mounted on the lower glue rod 205. A spring is provided between the gluing outer rod 207 and the gluing inner rod 208.

[0037] As Figure 3 shown, the pre-pressing mechanism includes two pre-pressing rods 209 rotatably mounted on the main frame 101. A pre-pressing roller 212 is rotatably mounted on the pre-pressing rod 209. A pre-pressing inner rod 210 is rotatably mounted on the pre-pressing rod 209. A pre-pressing outer rod 211 is rotatably mounted on the main frame 101. A spring is provided between the pre-pressing outer rod 211 and the pre-pressing inner rod 210.

[0038] Wind two rolls of film around the upper and lower film reel columns 202 respectively. Manually pull out the film. The film does not pass through between the gluing rollers 206, but passes by the outside of the gluing rollers 206. Subsequently, the film passes through between two groups of pre-pressing rollers 212. Then, the end of the upper film is fixed on the upper winding roller 114, and the end of the lower film is fixed on the lower winding roller 114.

[0039] First, insert the plate 313 between the two gluing rollers 206. Brush glue on the upper and lower surfaces of the plate 313 through the gluing rollers 206. Subsequently, the glued plate reaches between the first group of pre-pressing rollers 212 and is pasted to the upper and lower layers of film. Pre-press the plate 313 and the film through the two groups of pre-pressing rollers 212. Drive the film to wind up by rotating the winding roller 114. Drive the plate 313 to move forward together by the force of the film winding up. Subsequently, the plate 313 and the film reach between the pressing block 304 and the lower pressing block 311.

[0040] As Figures 4 - 7 shown, the film pressing device further includes a compression spring 303 provided between the outer cylinder 302 and the inner spring column 301. A film cutting groove 312 is provided in the lower pressing block 311. The plate 313 is conveyed into the film cutting groove 312. A cutting knife is provided on the edge of the film cutting groove 312 for cutting the film on the plate 313. A positioning groove 314 is provided on the lower surface of the pressing block 304. There are round corners around the positioning groove 314 for positioning the plate 313.

[0041] As Figures 4 - 7 shown, a lower pressing frame 305 is fixedly mounted on the pressing block 304. A lifting slider 306 is slidably mounted on the lower pressing frame 305. A lifting rod 308 is fixedly mounted on the rotating plate 307. A spring column 309 is fixedly mounted on the bottom plate 102. A tension spring 310 is provided between the spring column 309 and the lifting rod 308. A slope is provided on the lower surface of the lifting slider 306.

[0042] The sheet material 313 and the films on its upper and lower surfaces are conveyed together under the pressing block 304. The pressing block 304 descends and cooperates with the lower pressing block 311. At the same time, the pressing block 304 and the lower pressing block 311 are heated to press and bond the sheet material 313 and the films on its upper and lower surfaces. Meanwhile, the cutter at the edge of the cutting groove 312 cuts off the part where the film is adhered to the sheet material 313. The uncut part continues to be wound up. Since the width of the film roll is greater than the width of the sheet material 313, the film will not be cut off. When the pressing block 304 descends, it drives the lower pressing frame 305 to descend, thus driving the lifting slider 306 to descend. When the lifting slider 306 contacts the lifting rod 308, since the lifting rod 308 cannot descend, the lifting rod 308 pushes the lifting slider 306 to slide along the lower pressing frame 305 through the slope of the lifting slider 306. Subsequently, after the lifting slider 306 passes through the lifting rod 308, the lifting slider 306 slides back to its original position along the lower pressing frame 305 under the action of gravity. At this time, the lifting slider 306 is located below the lifting rod 308. Then, when the pressing block 304 descends to the lowest point, the cam 107 continues to rotate, the compression spring 303 rebounds, and the outer cylinder 302 and the pressing block 304 rise, thereby driving the lower pressing frame 305 and the lifting slider 306 to rise. The lifting slider 306 drives the lifting rod 308 to rise, thereby driving the rotating plate 307 to rotate relative to the lower pressing block 311. The tension spring 310 is stretched, and the sheet material 313 with the upper and lower films attached is lifted by the rotating plate 307. Subsequently, the sheet material 313 slides along the inclined rotating plate 307 onto the discharging slope 118 for discharging. Since the lifting rod 308 and the rotating plate 307 rotate around the lower pressing block 311, when the lifting slider 306 lifts the lifting rod 308 to a certain height, the lifting rod 308 will disengage from the lifting slider 306. Then, the tension spring 310 rebounds, causing the lifting rod 308 and the rotating plate 307 to return to their original positions, and the rotating plate 307 returns to its initial position.

[0043] The working principle of a double-sided molding device for a formaldehyde-free environmentally friendly antibacterial board disclosed by the present invention is as follows: Two rolls of film are respectively wound around the upper and lower film roll columns 202. The film is manually pulled out and does not pass through between the glue coating rollers 206, but passes by the outside of the glue coating rollers 206. Subsequently, the film passes through between two groups of pre-pressing rollers 212. Then, the end of the upper film is fixed on the upper winding roller 114, and the end of the lower film is fixed on the lower winding roller 114. The motor 103 rotates to drive the motor gear 104 to rotate, thereby driving the upper gear 105, the camshaft 106 and the cam 107 to rotate. Through the meshing of every two upper gears 105 with each other, all cams 107 are driven to rotate synchronously. The cam 107 drives the pressure block 304 to continuously rise and fall. The rightmost camshaft 106 drives the upper winding transmission belt 112 and the winding wheel 110 to rotate through the transmission belt 109, and drives the lower winding transmission belt 112 and the winding wheel 110 to rotate synchronously through the intermediate transmission belt 113. The winding roller 114 is driven to rotate through the winding transmission belt 112, and the film is driven to wind by the rotation of the two winding rollers 114. First, the board 313 is inserted between the two glue coating rollers 206, and the upper and lower surfaces of the board 313 are brushed with glue by the glue coating rollers 206. Subsequently, the glued board reaches between the first group of pre-pressing rollers 212 and is pasted with the upper and lower layers of film. The two groups of pre-pressing rollers 212 pre-press the board 313 and the film. The winding roller 114 rotates to drive the film to wind, and the force of the film winding drives the board 313 to move forward together. Subsequently, the board 313 and the film reach between the pressure block 304 and the board 313.The sheet material 313 and the films on its upper and lower surfaces are conveyed together under the pressing block 304. The pressing block 304 descends and cooperates with the lower pressing block 311. At the same time, the pressing block 304 and the lower pressing block 311 are heated, which will press and bond the sheet material 313 and the films on its upper and lower surfaces. Meanwhile, the cutter at the edge of the cutting groove 312 cuts off the part where the film is adhered to the sheet material 313. The uncut part continues to be wound up, and the width of the film roll is greater than the width of the sheet material 313, so the film will not be cut off. When the pressing block 304 descends, it will drive the lower pressing frame 305 to descend, thereby driving the lifting slider 306 to descend. When the lifting slider 306 contacts the lifting rod 308, since the lifting rod 308 cannot descend, the lifting rod 308 pushes the lifting slider 306 to slide along the lower pressing frame 305 through the slope surface of the lifting slider 306. Subsequently, after the lifting slider 306 passes through the lifting rod 308, the lifting slider 306 slides back to its original position along the lower pressing frame 305 under the action of gravity. At this time, the lifting slider 306 is located below the lifting rod 308. Subsequently, when the pressing block 304 descends to the lowest point, the cam 107 continues to rotate, the compression spring 303 rebounds, and the outer cylinder 302 and the pressing block 304 rise, thereby driving the lower pressing frame 305 and the lifting slider 306 to rise. The lifting slider 306 drives the lifting rod 308 to rise, thereby driving the rotating plate 307 to rotate relative to the lower pressing block 311. The tension spring 310 is stretched, and the sheet material 313 with the upper and lower films attached is lifted by the rotating plate 307. Subsequently, the sheet material 313 slides along the inclined rotating plate 307 onto the discharging slope 118 for discharging. Since the lifting rod 308 and the rotating plate 307 rotate around the lower pressing block 311, when the lifting slider 306 lifts the lifting rod 308 to a certain height, the lifting rod 308 will disengage from the lifting slider 306. Subsequently, the tension spring 310 rebounds, causing the lifting rod 308 and the rotating plate 307 to return to their original positions, and the rotating plate 307 returns to its initial position.

[0044] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope of the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
