Description

Technical Field

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

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

[0006] The rotation of the motor drives the motor gear to rotate, thereby driving the upper gear, camshaft and cam to rotate. Through the mutual engagement between every two upper gears, all cams are driven to rotate synchronously. The cam drives the pressure block to rise and fall continuously. The camshaft on the far right drives the upper winding belt and winding wheel to rotate through the transmission belt, drives the lower winding belt and winding wheel to rotate synchronously through the middle transmission belt, drives the winding roller to rotate through the winding belt, and drives the film to be wound through the rotation of the two winding rollers.

[0007] Furthermore, the placement device also includes an inner placement rod rotatably mounted on the placement frame, an outer placement rod rotatably mounted on the main frame, and a spring is arranged between the inner placement rod and the outer placement rod.

[0008] Furthermore, the glue coating mechanism includes two glue rods rotatably mounted on the main frame, a glue coating roller is rotatably mounted on the glue rods, the glue coating roller is filled with glue, an inner glue coating rod is rotatably mounted on the upper glue rod, and an outer glue coating rod is rotatably mounted on the lower glue rod, and a spring is arranged between the outer glue coating rod and the inner glue coating rod.

[0009] Furthermore, the prestressing mechanism includes two prestressing rods rotatably mounted on the main frame, a prestressing roller is rotatably mounted on the prestressing rod, a prestressing inner rod is rotatably mounted on the prestressing rod, a prestressing outer rod is rotatably mounted on the main frame, and a spring is arranged between the prestressing outer rod and the prestressing inner rod.

[0010] Wrap the two rolls of film around the upper and lower film roll columns respectively, and pull the film out manually. The film does not pass between the glue coating rollers, but passes from the outside of the glue coating roller. Then the film passes between the two sets of pre-pressing rollers, and 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.

[0011] First, insert the sheet into between two glue coating rollers, and use the glue coating rollers to brush glue on the upper and lower surfaces of the sheet. Then, the glue-coated sheet reaches between the first set of pre-pressing rollers and sticks to the upper and lower layers of film. The sheet and film are pre-pressed by the two sets of pre-pressing rollers, and the film is rolled up by the rotation of the winding roller. The sheet is driven forward by the force of the film rolling up, and then the sheet and film reach between the pressing block and the lower pressing block together.

[0012] Furthermore, the film pressing device also 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 plate is conveyed into the breaking groove, a cutting knife is arranged on the edge of the breaking groove for cutting the film on the plate, and a positioning groove is arranged on the lower surface of the pressing block, and the positioning groove has rounded corners around it for positioning the plate.

[0013] Furthermore, 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 plate, a spring column is fixedly installed on the bottom plate, a tension spring is arranged between the spring column and the lifting rod, and a slope is arranged on the lower surface of the lifting slider.

[0014] The sheet and the films on its upper and lower surfaces are transported to the bottom of the pressing block together. 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 the sheet and the films on its upper and lower surfaces together. At the same time, the cutter at the edge of the pressure-breaking groove cuts off the part where the film and the sheet are in contact. The uncut part continues to be rolled up, and the width of the film roll is greater than the width of the sheet, so the film will not be cut. 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 moves along the lower pressing frame under the action of gravity. The pressing frame slides to reset, and the lifting slider is now located under the lifting rod. Then, when the pressing block drops 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, and the lifting slider drives the lifting rod to rise, thereby driving the turn-out plate to rotate relative to the lower pressing block. The tension spring is stretched, and the upper and lower film-laminating plates are lifted through the turn-out plate, and then the plates slide along the inclined turn-out plate to the plate outlet slope for unloading. Since the lifting rod and the turn-out plate rotate around the lower pressing block, when the lifting slider lifts the lifting rod to a certain height, the lifting rod will be separated from the lifting slider, and then the tension spring rebounds, causing the lifting rod and the turn-out plate to reset, and the turn-out plate returns to its initial position.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) the placing device provided in the present invention first applies glue to the sheet to be molded, thereby enhancing the bonding effect between the upper and lower surfaces of the sheet and the film, and at the same time pre-presses the sheet and the film through two pre-pressing mechanisms, thereby improving the quality of subsequent double-sided molding of the sheet; (2) the winding mechanism provided in the present invention can roll up the film on the upper and lower surfaces of the sheet, and after the sheet is coated and the sheet and the film are pre-pressed, the sheet is driven to move together by the film rolling, and then the film on both sides of the sheet is hot-pressed on the sheet through the film pressing device, with a high degree of automation and good continuity; (3) when the pressing block provided in the present invention descends, it will not drive the lifting rod to move, and when the pressing block rises, it will lift one end of the lifting rod, so that the sheet after molding is slid onto the plate discharge slope, thereby realizing automatic discharge.

[0028] The rotation of motor 103 drives the motor gear 104 to rotate, thereby driving the upper gear 105, camshaft 106 and cam 107 to rotate. Through the mutual engagement between every two upper gears 105, all cams 107 are driven to rotate synchronously, and the pressure block 304 is driven to rise and fall continuously through the cam 107. The camshaft 106 on the far right drives the upper winding transmission belt 112 and winding wheel 110 to rotate through the transmission belt 109, and drives the lower winding transmission belt 112 and winding wheel 110 to rotate synchronously through the middle transmission belt 113, and drives the winding roller 114 to rotate through the winding transmission belt 112, and the film is wound up through the rotation of the two winding rollers 114.

[0030] like Figure 3 As shown, the gluing mechanism includes two glue rods 205 rotatably mounted on the main frame 101, a glue coating roller 206 is rotatably mounted on the glue rod 205, and the glue coating roller 206 is filled with glue. An inner glue coating rod 208 is rotatably mounted on the upper glue rod 205, and an outer glue coating rod 207 is rotatably mounted on the lower glue rod 205, and a spring is arranged between the outer glue coating rod 207 and the inner glue coating rod 208.

[0031] like Figure 3As shown, the prestressing mechanism includes two prestressing rods 209 rotatably mounted on the main frame 101, a prestressing roller 212 is rotatably mounted on the prestressing rod 209, a prestressing inner rod 210 is rotatably mounted on the prestressing rod 209, a prestressing outer rod 211 is rotatably mounted on the main frame 101, and a spring is arranged between the prestressing outer rod 211 and the prestressing inner rod 210.

[0032] Wrap the two rolls of film around the upper and lower film roll columns 202 respectively, and pull the film out manually. The film does not pass between the glue coating rollers 206, but passes from the outside of the glue coating rollers 206. Then the film passes between the two sets of pre-pressing rollers 212, and 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.

[0033] First, the sheet 313 is inserted between the two glue coating rollers 206, and glue is applied to the upper and lower surfaces of the sheet 313 by the glue coating rollers 206. Then, the glue-coated sheet arrives between the first set of pre-pressing rollers 212 and adheres to the upper and lower layers of film. The sheet 313 and the film are pre-pressed by the two sets of pre-pressing rollers 212, and the film is rolled up by the rotation of the winding roller 114. The sheet 313 is driven forward together by the force of the film rolling up, and then the sheet 313 and the film arrive between the pressing block 304 and the lower pressing block 311 together.

[0034] like Figure 4-Figure 7 As shown, the film pressing device also includes a compression spring 303 arranged between the outer cylinder 302 and the inner spring column 301, a breaking groove 312 is arranged in the lower pressing block 311, and the plate 313 is conveyed into the breaking groove 312. A cutting knife is arranged on the edge of the breaking groove 312 for cutting the film on the plate 313. A positioning groove 314 is arranged on the lower surface of the pressing block 304. The positioning groove 314 has rounded corners around it for positioning the plate 313.

[0035] like Figure 4-Figure 7 As shown, a lower pressing frame 305 is fixedly installed on the pressing block 304, a lifting slider 306 is slidably installed on the lower pressing frame 305, a lifting rod 308 is fixedly installed on the rotating plate 307, a spring column 309 is fixedly installed on the bottom plate 102, a tension spring 310 is arranged between the spring column 309 and the lifting rod 308, and a slope is arranged on the lower surface of the lifting slider 306.

[0036] The sheet 313 and the films on its upper and lower surfaces are transported together to the bottom of the pressing block 304, and the pressing block 304 descends and cooperates with the lower pressing block 311, and at the same time, the pressing block 304 and the lower pressing block 311 are heated to press the sheet 313 and the films on its upper and lower surfaces together, and at the same time, the cutting knife at the edge of the pressing groove 312 cuts off the part where the film and the sheet 313 are in contact, and the uncut part continues to be rolled up, and the width of the film roll is greater than the width of the sheet 313, so the film will not be cut. 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 of the lifting slider 306, and then after the lifting slider 306 passes the lifting rod 308, the lifting slider 306 slides along the lower pressing frame 305 under the action of gravity to reset. At this time The lifting slider 306 is located below the lifting rod 308. Then, when the pressure block 304 drops to the lowest point, the cam 107 continues to rotate, the compression spring 303 rebounds, the outer cylinder 302 and the pressure block 304 rise, thereby driving the lower pressure frame 305 and the lifting slider 306 to rise, and the lifting slider 306 drives the lifting rod 308 to rise, thereby driving the roll-out plate 307 to rotate relative to the lower pressure block 311, the tension spring 310 is stretched, and the upper and lower films are completely pasted through the roll-out plate 307. The formed plate 313 is lifted, and then the plate 313 slides along the inclined turn-out plate 307 to the plate outlet slope 118 for discharge. Since the lifting rod 308 and the turn-out 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 be disengaged from the lifting slider 306, and then the tension spring 310 rebounds, so that the lifting rod 308 and the turn-out plate 307 are reset, and the turn-out plate 307 returns to the initial position.

[0037] The working principle of the double-sided molding device of the formaldehyde-free, environmentally friendly and antibacterial plate disclosed in the present invention is: two rolls of film are respectively wound on the upper and lower film roll columns 202, and the film is manually pulled out. The film does not pass between the glue coating rollers 206, but passes from the outside of the glue coating rollers 206. Then the film passes between the two groups of pre-pressing rollers 212, and 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 rotation of motor 103 drives the motor gear 104 to rotate, thereby driving the upper gear 105, camshaft 106 and cam 107 to rotate. Through the mutual engagement between every two upper gears 105, all cams 107 are driven to rotate synchronously, and the pressure block 304 is driven to rise and fall continuously through the cam 107. The camshaft 106 on the far right drives the upper winding transmission belt 112 and winding wheel 110 to rotate through the transmission belt 109, and drives the lower winding transmission belt 112 and winding wheel 110 to rotate synchronously through the middle transmission belt 113, and drives the winding roller 114 to rotate through the winding transmission belt 112, and the film is wound up through the rotation of the two winding rollers 114. First, the sheet 313 is inserted between the two glue coating rollers 206, and glue is applied to the upper and lower surfaces of the sheet 313 by the glue coating rollers 206. Then, the glue-coated sheet arrives between the first set of pre-pressing rollers 212 and adheres to the upper and lower layers of film. The sheet 313 and the film are pre-pressed by the two sets of pre-pressing rollers 212, and the film is rolled up by the rotation of the winding roller 114. The sheet 313 is driven forward together by the force of the film rolling up, and then the sheet 313 and the film arrive between the pressing block 304 and the sheet 313 together.The sheet 313 and the films on its upper and lower surfaces are conveyed together to the bottom of the pressing block 304, and 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, and the sheet 313 and the films on its upper and lower surfaces are pressed together. At the same time, the cutting knife at the edge of the pressing groove 312 cuts off the part where the film and the sheet 313 are in contact, and the uncut part continues to be rolled up. The width of the film roll is greater than the width of the sheet 313, so the film will not be cut. When the pressing block 304 descends, it drives 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 of the lifting slider 306. Then, after the lifting slider 306 passes the lifting rod 308, the lifting slider 306 slides and resets 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 pressure block 304 drops to the lowest point, the cam 107 continues to rotate, the compression spring 303 rebounds, the outer cylinder 302 and the pressure block 304 rise, thereby driving the lower pressure frame 305 and the lifting slider 306 to rise, and the lifting slider 306 drives the lifting rod 308 to rise, thereby driving the roll-out plate 307 to rotate relative to the lower pressure block 311, the tension spring 310 is stretched, and the upper and lower films are completely pasted through the roll-out plate 307. The formed plate 313 is lifted, and then the plate 313 slides along the inclined turn-out plate 307 to the plate outlet slope 118 for discharge. Since the lifting rod 308 and the turn-out 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 be disengaged from the lifting slider 306, and then the tension spring 310 rebounds, so that the lifting rod 308 and the turn-out plate 307 are reset, and the turn-out plate 307 returns to the initial position.
