[0013] Furthermore, a method for using a fully automatic hot pressing device for producing an LCD liquid crystal display screen is provided. The method comprises the following steps: S1: First, place the material to be hot-pressed on the lower pressing plate, then the staff pushes the lower pressing plate to make it at the bottom of the upper pressing plate, and then starts the heating element inside the upper pressing plate; S2: Start the hydraulic rod and the fan at the same time. When the hydraulic rod is working, it will push the upper and lower pressing plates to close. After the internal heating element of the upper pressing plate is heated for a period of time; S3: Start the hydraulic rod again, and the upper pressing plate rises to complete the hot pressing work.

[0014] The present invention has the following beneficial effects: 1. In the present invention, when the staff starts the fan, the wind force generated by the fan will enter the fixed frame through the air outlet pipe. When the gas enters the fixed frame, it will first impact the surface of the fan shaft. When the gas impacts the fan shaft, the fast-flowing gas will cause the large fan shaft to rotate. When the fan shaft rotates, it will drive the disc to rotate. When the disc rotates, the elliptical groove opened through the side wall of the disc will squeeze the hollow plate, so that the hollow plate slides back and forth on the surface of the limit rod. When the hollow plate slides, the sliding hollow plate will drive the arc plate to reciprocate inside the upper pressure plate. When the arc plate rotates, the rotating arc plate will drive multiple T-shaped plates on the long rod to move downward through the long rod. When the T-shaped plate moves downward, the moving T-shaped The plate will make the elastic plate at the bottom contact with the top of the airbag plate, and then when the T-plate moves down, the airbag plate will squeeze the elastic plate, and the elastic plate will push the C-plate after being squeezed, so that the C-plate contacts the surface of the airbag plate, and under the push of the elastic plate, the C-plate will slide relatively on the top of the airbag plate. When the T-plate moves down and the C-plate slides, the top of the airbag plate can be pressed. When the arc plate rotates back and forth, the pressing mechanism can generate uniform pressing force on the top of the airbag plate when pressing. Since the pressure is more uniform, the surface of the material after hot pressing is smoother and the internal bonding is tighter, thereby improving the overall quality and performance of the product. At the same time, due to the uniform pressure, the hot pressing effect is more stable and reliable, which helps to improve production efficiency.

[0015] 2. In the present invention, when the gas is ejected from the curved tube, the ejected gas will be mixed with the heat generated by the upper pressure plate inside the upper pressure plate, and then during the rotation of the arc plate, the piston plate will be driven by the C-rod to make it move back and forth inside the piston box, and when the piston plate moves upward inside the piston box, negative pressure will be generated at the bottom of the piston box, and when the piston plate moves to the top of the air outlet, the negative pressure will draw the mixed hot gas inside the upper pressure plate into the piston box, and then when the piston plate moves downward, the piston plate will squeeze the gas inside the piston box, so that it enters the airbag plate through the connecting pipe 2. At this time, the one-way plate has the effect of gas reflux in the connecting pipe 2, and then when a steady stream of gas enters the airbag plate, the airbag plate will expand. At this time, the expanded airbag plate can form a buffer layer between the material and the pressing mechanism, which plays a certain buffering role in the process of pressing by the pressing mechanism, reducing the damage to the material caused by excessive pressure of the pressing mechanism during the pressing process, and reducing the structural damage between the material components.

[0016] 3. In the present invention, when the upper pressure plate and the lower pressure plate are closed, the lower pressure plate will block the multiple conical nozzles in the piston plate. When the hot pressing is completed and the upper pressure plate is separated from the lower pressure plate, the continuously moving piston plate will continuously squeeze the gas. Since the piston plate has been squeezing the gas for a long time, the gas inside the airbag plate has been saturated. Then, when the piston plate continues to move downward, the gas will enter the gas collecting frame from the connecting pipe three. Since part of the gas has entered the gas collecting frame when the material is hot pressed, when the lower pressure plate is separated from the conical nozzle and the gas enters the gas collecting frame through the connecting pipe three, the gas inside the auxiliary mechanism will be ejected from the conical nozzle and sprayed onto the surface of the material. Since the conical nozzle is in a cone shape, when the hot air passes through the conical air outlet, due to the reduction in gas volume and the increase in flow rate, a certain heat dissipation effect will be produced, thereby reducing the temperature of the hot air, helping to quickly stabilize the material temperature, thereby accelerating the cooling time of the material and improving product quality.

[0017] 4. In the present invention, when the gas blows the fan shaft to make it rotate, the rotating fan shaft will drive the disc to rotate, and the disc will drive the gear ring on the side wall to rotate synchronously when rotating. When the gear ring rotates, the gear ring will drive the rotating shaft with teeth to rotate, and when the rotating shaft rotates, it will drive the arc plate 2 to rotate inside the gas collecting frame. Since the rotating shaft and the gas collecting frame are eccentrically arranged, when the rotating shaft drives the arc plate 2 to rotate, the rotating arc plate 2 will extract the gas inside the fixed frame into the gas collecting frame through the connecting pipe, and then the gas will be pressurized under the rotation of the arc plate 2 driven by the rotating shaft, and then the pressurized gas will be ejected through the curved tube. Since the curved tube is curved, when the gas is ejected through the curved tube, the gas will blow onto the grille plate to make it rotate. When the grille plate rotates, it will drive the sliding sleeve to rotate through the rotating shaft 2. At this time, under the rotation of the arc plate, The rotating arc plate will drive the sliding sleeve to slide downward on the outer surface of the second rotating shaft through the T-bar. When the sliding sleeve slides downward, the sliding sliding sleeve will drive the movable plate through the L plate to make the movable plate slide on the hollow arc plate. At this time, there will be a certain angle between the movable plate and the H frame when sliding. Then, under the rotation of the second rotating shaft, the rotating second rotating shaft will drive the movable plate to rotate through the hollow arc plate. During the rotation of the movable plate, the rotating movable plate will drive the H frame to swing back and forth through the C-shaped block at the bottom. When the H frame swings, the swinging H frame will generate a driving force on the surface of the airbag plate at the top of the airbag plate. Under the reciprocating push of the H frame, the gas entering the inside of the airbag plate through the connecting pipe 2 can be quickly and evenly distributed inside the airbag plate, so that it can respond quickly between the pressing of the pressing mechanism, thereby enhancing the airbag plate protection effect of this device.

[0031] The outer surface of the airbag plate 806 is provided with a cooling mechanism 9, which includes an air collecting frame 902 slidably connected to the outer surface of the airbag plate 806, and the front and back inner walls of the air collecting frame 902 are fixedly connected with a plurality of conical nozzles 903, and the front outer wall of the air collecting frame 902 is fixedly connected with a plurality of connecting pipes 3 901, and the plurality of connecting pipes 3 901 penetrate the outer wall of the upper pressure plate 105 and are fixedly connected to the side wall of the piston box 803, and the connecting pipes 3 901 are connected with the piston box 803. When the upper pressure plate 105 and the lower pressure plate 101 are closed, the lower pressure plate 101 will block the multiple conical nozzles 903 in the piston plate 802. When the hot pressing is completed and the upper pressure plate 105 is separated from the lower pressure plate 101, the continuously moving piston plate 802 will continuously squeeze the gas. Since the piston plate 802 has been squeezing the gas for a long time, the gas inside the airbag plate 806 has been saturated. Therefore, when the piston plate 802 continues to move downward, the gas will enter the gas collecting frame 902 from the connecting pipe three 901.

[0032] A method for using a fully automatic hot pressing device for producing an LCD liquid crystal display screen, the method comprising the following steps: S1: First, the material to be hot-pressed is placed on the lower pressing plate 101, and then the staff pushes the lower pressing plate 101 to make the lower pressing plate 101 at the bottom of the upper pressing plate 105, and then starts the heating element inside the upper pressing plate 105; S2: start the hydraulic rod 103 and the fan 201 at the same time. When the hydraulic rod 103 is working, it will push the upper pressing plate 105 and the lower pressing plate 101 to close. After the internal heating element of the upper pressing plate 105 is heated for a period of time; S3: Start the hydraulic rod 103 again, and the upper pressing plate 105 rises to complete the hot pressing work.

[0033] When in use, first place the material to be hot-pressed on the lower pressing plate 101, then the staff pushes the lower pressing plate 101 so that the lower pressing plate 101 is at the bottom of the upper pressing plate 105, then starts the heating element inside the upper pressing plate 105, and starts the hydraulic rod 103 and the fan 201 at the same time. When the hydraulic rod 103 is working, it will push the upper pressing plate 105 and the lower pressing plate 101 to close. After the heating element inside the upper pressing plate 105 is heated for a period of time, the hydraulic rod 103 is started again. At this time, the upper pressing plate 105 rises to complete the hot pressing work. When the gas is ejected from the curved tube 504, the ejected gas will be mixed with the heat generated by the upper pressure plate 105 inside the upper pressure plate 105, and then during the rotation of the arc plate 303, the piston plate 802 will be driven by the C-shaped rod 801 to make it reciprocate inside the piston box 803. When the piston plate 802 moves upward inside the piston box 803, negative pressure will be generated at the bottom of the piston box 803. When the piston plate 802 moves to the top of the air outlet, the negative pressure will draw the mixed hot gas inside the upper pressure plate 105 into the piston box 803. Then, when the piston plate 802 moves downward, the piston Plate 802 will squeeze the gas inside the piston box 803, causing it to enter the airbag plate 806 through the connecting tube 804. At this time, the one-way plate 805 has a gas reflux effect in the connecting tube 804. Thereafter, when a steady stream of gas enters the airbag plate 806, the airbag plate 806 will expand. At this time, the expanded airbag plate 806 can form a buffer layer between the material and the pressing mechanism 4, which plays a certain buffering role during the pressing process of the pressing mechanism 4, reducing the damage to the material caused by excessive pressure of the pressing mechanism 4 during the pressing process, and reducing the structural damage between the material components. When the upper pressing plate 105 and the lower pressing plate 101 are closed, the lower pressing plate 101 will block the multiple conical nozzles 903 in the piston plate 802. When the hot pressing is completed and the upper pressing plate 105 is separated from the lower pressing plate 101, the continuously moving piston plate 802 will continuously squeeze the gas. Since the piston plate 802 has been squeezing the gas for a long time, the gas inside the airbag plate 806 has been saturated. Then, when the piston plate 802 continues to move downward, the gas will enter the gas collecting frame 902 from the connecting pipe 3 901. Since some gas has entered during the hot pressing of the material, When the lower pressure plate 101 is separated from the conical nozzle 903 and the gas enters the gas collecting rack 902 through the connecting pipe 901, the gas inside the auxiliary mechanism 5 will be ejected from the conical nozzle 903 and sprayed onto the surface of the material. Since the conical nozzle 903 is conical in shape, when the hot air passes through the conical air outlet, due to the reduction in gas volume and the increase in flow rate, a certain heat dissipation effect will be produced, thereby reducing the temperature of the hot air, helping to quickly stabilize the material temperature, thereby accelerating the cooling time of the material and improving product quality.When the gas blows the fan shaft 204 to make it rotate, the rotating fan shaft 204 will drive the disc 205 to rotate, and the disc 205 will drive the gear ring on the side wall to rotate synchronously when rotating. When the gear ring rotates, the gear ring will drive the rotating shaft 502 with teeth to rotate, and the rotating shaft 502 will drive the arc plate 2 503 to rotate inside the gas collecting frame 501. Since the rotating shaft 502 and the gas collecting frame 501 are eccentrically arranged, when the rotating shaft 502 drives the arc plate 2 503 to rotate, the rotating arc plate 2 503 will pass through The connecting pipe 505 draws the gas inside the fixed frame 203 into the gas collecting frame 501, and then the gas is pressurized under the rotation of the arc plate 203 driven by the rotating shaft 502, and then the pressurized gas is ejected through the curved pipe 504. Since the curved pipe 504 is curved, when the gas is ejected through the curved pipe 504, the gas will blow onto the grid plate 603, causing it to rotate. When the grid plate 603 rotates, the sliding sleeve 604 is driven to rotate through the rotating shaft 2 602. At this time, under the rotation of the arc plate 303, the rotating arc plate 303 03 will drive the sliding sleeve 604 to slide downward on the outer surface of the second rotating shaft 602 through the T-shaped rod 304. When the sliding sleeve 604 slides downward, the sliding sliding sleeve 604 will drive the movable plate 702 through the L plate 701, so that the movable plate 702 slides on the hollow arc plate 605. At this time, when the movable plate 702 slides, there will be a certain angle between it and the H frame 703. Then, when the second rotating shaft 602 rotates, the rotating second rotating shaft 602 will drive the movable plate 702 to rotate through the hollow arc plate 605. During the process, the rotating movable plate 702 will drive the H-frame 703 to swing back and forth through the C-shaped block at the bottom. When the H-frame 703 swings, the swinging H-frame 703 will generate a driving force on the surface of the airbag plate 806 at the top of the airbag plate 806. Under the reciprocating push of the H-frame 703, the gas entering the airbag plate 806 through the connecting tube 2 804 can be quickly and evenly distributed inside the airbag plate 806, so that it can respond quickly between the pressing of the pressing mechanism 4, thereby enhancing the protective effect of the airbag plate 806 of this device.
