Description

Technical Field

[0001] This invention relates to the field of constant temperature and pressure bonding technology for plastic sheets, specifically a constant temperature and pressure bonding device for plastic sheets used in eyeglass frames. Background Technology

[0002] Specialized plastic sheets for eyeglass frames are the core substrate for producing acetate eyeglass frames. They are primarily made from high-quality raw materials such as cellulose acetate and high-molecular composite plastics, making them environmentally friendly and skin-friendly, causing no irritation upon contact with the skin. They also possess excellent toughness, bending resistance, and thermal stability, making them resistant to cracking, deformation, and fading with daily use. These sheets come in a variety of colors, have natural textures, and a delicate surface finish. They offer excellent processing adaptability, allowing for layer cutting, multi-layer constant-temperature pressure bonding, grinding, bending, and polishing. The resulting frames are structurally stable and aesthetically pleasing, widely used in the production of various acetate eyeglasses, including optical frames, fashionable non-prescription glasses, and casual sunglasses.

[0003] Chinese patent CN210999697U discloses a hot-pressing mold for producing plastic sheets, including a base, a shelf fixedly connected to the center of the top of the base, a storage box movably connected to the bottom of the inner wall of the shelf, a fan fixedly connected to the center of the bottom of the inner wall of the storage box, sliders fixedly connected to the center of the left and right sides of the storage box, a support rod fixedly connected to the center of the back of the base, a top plate fixedly connected to the center of the top of the support rod, an electric telescopic rod fixedly connected to the center of the bottom of the top plate, and a hot press box fixedly connected to the center of the bottom of the electric telescopic rod. Through the setting of a rubber stopper and a water inlet pipe, in conjunction with a water outlet pipe, the operator can remove the rubber stopper to pour coolant into the water inlet pipe and spray it onto the mold on the top of the shelf through the water outlet pipe, thereby cooling the mold fluid and accelerating the cooling rate of the plastic sheet after hot pressing. This technical solution relies solely on manual water spraying for cooling and a simple bottom fan for air cooling. It lacks a forced water circulation structure, resulting in slow cooling flow, uneven heat exchange, and poor temperature stability. The sheet metal is prone to internal stress, warping, and delamination defects. Additionally, dust easily remains inside the mold cavity, requiring manual cleaning during machine shutdown. Furthermore, its simple heat dissipation and ventilation structure makes it easy for dust to enter the equipment and cause air duct blockage when the machine is stopped. Summary of the Invention

[0011] Please see Figures 1-3 This invention provides a constant temperature and pressure bonding device for plastic sheets used in eyeglass frames, comprising: The base 1 has a pressing component 6 fixedly connected to the middle of its top, a cleaning component 9 fixedly connected to the side of the pressing component 6, a water cooling component 8 fixedly connected to one side of the base 1, and a negative pressure collection component 7 fixedly connected to the other side of the base 1. Guide post 2, which is evenly arranged on the top of base 1, the bottom of guide post 2 is fixedly connected to the top of base 1, and a top plate 5 is fixedly connected to the top of guide post 2. A driving component 4 is fixedly connected to the middle of the top of top plate 5. The upper heating plate 3 has its inner side slidably connected to the side of the guide post 2, and its top is fixedly connected to the output end of the drive component 4. Example 1, please refer to Figures 4-6 The invention also includes a pressing component 6, a collection box 71 fixedly connected to the side of the base 1, a negative pressure fan 72 fixedly connected to the bottom of the inner cavity of the collection box 71, and a filter screen fixedly connected to the top of the negative pressure fan 72. Collection pipes 73 are fixedly connected to both sides of the top of the collection box 71, and the other end of the collection pipe 73 is fixedly connected to the inner side of the air-cooling groove 63. The bottom of the pressing plate 61 is fixedly connected to the top of the base 1. A water-cooling groove 62 is opened around the inner side of the pressing plate 61, and an air-cooling groove 63 is opened around the inner side of the pressing plate 61 and passes through the water-cooling groove 62. While the pressing plate 61 and the plate are cooled by water cooling, the negative pressure fan 72 in the collection box 71 is started. The fan generates negative pressure and forms a directional airflow in the air-cooling groove 63 inside the pressing plate 61 through the collection pipe 73. A ventilation mechanism 65 is fixedly connected to the inner side of the air-cooled trough 63. The ventilation mechanism 65 in the air-cooled trough 63 is opened by the negative pressure gas, and the outside air is introduced to form convection. Fresh outside air is continuously replenished into the inner space of the lower pressure plate 61 to form forced convection air cooling. The airflow directly cools the inner side of the lower pressure plate 61 and the plate material. The airflow flows along the surrounding air cooling grooves 63, washes the outer wall of the water cooling pipe 82, and assists in cooling the water cooling pipe 82, thereby greatly accelerating the overall cooling speed. The side of the ejector plate 66 is slidably connected to the inside of the base 1. The bottom of the ejector rod 67 is fixedly connected to the top of the ejector plate 66. A second cylinder 68 is fixedly connected to the inside of the base 1. The output end of the second cylinder 68 is fixedly connected to the bottom of the ejector plate 66. The ejector groove 64 is wider at the top and narrower at the bottom. The ejector groove 64 is evenly opened on the inside of the lower pressure plate 61. The upper wide part of the ejector groove 64 is connected to the air cooling groove 63. The ejector rod 67 is wider at the top and narrower at the bottom. The side of the ejector rod 67 is slidably connected to the inside of the ejector groove 64. When the lower pressure plate 61 and the internal plate are cooled, the second cylinder 68 is opened. The output end of the second cylinder 68 pushes the ejector plate 66 to move upward in the inner cavity of the base 1, which drives the ejector rod 67 on the ejector plate 66 to move upward synchronously along the corresponding ejector groove 64, ejecting the plate placed in the lower pressure plate 61, realizing automatic ejection, and facilitating material handling. Please see Figure 7 The invention also includes a ventilation mechanism 65, wherein the side of the ventilation pipe 651 is fixedly connected to the inner side of the air-cooled groove 63, and the negative pressure fan 72 in the air collection box is started to continuously draw air from the air-cooled groove 63 of the lower pressure plate 61. One end of the circular shaft 654 is fixedly connected to a circular block 655, and the other end of the circular shaft 654 is fixedly connected to a circular block 657. The sides of both the circular block 655 and the circular block 657 are slidably connected to the inside of the ventilation pipe 651. The negative pressure causes the circular block 657 inside the ventilation pipe 651 to move. The circular block 657 pulls the circular block 655 through the circular shaft 654, causing the circular block 655 to disengage from the inside of the ventilation pipe 651. This allows outside air to continuously enter the air-cooled slot 63 inside the lower pressure plate 61 through the ventilation pipe 651, completing the ventilation and convection heat dissipation. A spiral blade 652 is fixedly connected to the middle of the ventilation duct 651, and a round shaft 654 is slidably connected to the inner side of the spiral blade 652. The ventilation duct 651 adopts a structure that is wide at both ends and narrow in the middle. The spiral blade 652 is provided in the narrow middle section, which can guide the airflow entering from the outside in layers. A circular plate 653 is fixedly connected to the side of the spiral blade 652 near the circular block 655. A spring 656 is sleeved on the circular shaft 654. Under normal pressure, the spring 656 pushes the circular block 655 to press against the wide end of the ventilation pipe 651. At the same time, the circular shaft 654 links the circular block 2 to close the ventilation pipe 651, blocking external impurities from entering and preventing the ventilation pipe 651 from becoming blocked. Please see Figure 8 The present invention also includes a water-cooling component 8. The water-cooling box 81 is fixedly connected to the side of the base 1. The water inlet end of the water-cooling pipe 82 is fixedly connected to a water pump 84. When performing water-cooling cooling operation, the water pump 84 is started to draw cold water from the water-cooling box 81 and continuously send it into the water-cooling pipe 82 of the lower pressure plate 61. A water-cooling pipe 82 is fixedly connected to the inside of the water-cooled box 81. The side of the water-cooling pipe 82 is fixedly connected to the inside of the water-cooling tank 62. The water-cooling pipe 82 is set to fit the water-cooling tank 62. When the water flows in the pipe, it continuously removes the heat from the inside of the pressure plate 61 and the plate through heat exchange, thereby achieving cooling. A water pump 83 is fixedly connected to the outlet end of the water-cooled pipe 82. When the water pump 83 is started, the water that has completed heat exchange in the water-cooled pipe 82 is continuously returned to the water-cooled box 81, which increases the overall water flow speed in the pipe and further accelerates the cooling efficiency of the lower pressure plate 61. A mesh plate frame 85 is fixedly connected to the inside of the water-cooled box 81. The mesh plate frame 85 is installed inside the water-cooled box 81 to filter the flowing water and intercept solid impurities in the water, so as to prevent impurities from being sucked into the water-cooled pipe 82 by the water pump 84 and causing pipe blockage. Please see Figures 9-11The invention also includes a cleaning component 9. The side of the baffle 92 is slidably connected to the inner side of the lower pressure plate 61. Sliding shafts 91 are fixedly connected to both sides of the bottom of the baffle 92. The bottom of the sliding shafts 91 is slidably connected to the top of the lower pressure plate 61. A spring 93 is sleeved on the sliding shafts 91. After the material is removed, the upper heating plate 3 returns to its original position. The template on the side of the upper heating plate 3 releases the pressure on the baffle 92. Under the reset action of the sliding shafts 91 on both sides and the spring 93, the baffle 92 resets upward along the inner side of the lower pressure plate 61. After the residual material debris on the inner side of the lower pressure plate 61 is blown away by an air gun, fine adhesive powder will still remain in the inner cavity of the lower pressure plate 61. The side of the fixed plate 95 is fixedly connected to the inner side of the lower pressure plate 61. A cylinder 94 is fixedly connected to the middle of the fixed plate 95. A movable frame 96 is fixedly connected to the output end of the cylinder 94. When the cylinder 94 is started, the output end of the cylinder 94 drives the movable frame 96 to move, so that the movable frame 96 is separated from the inner edge of the lower pressure plate 61 and extends into the interior of the lower pressure plate 61. The side of the movable frame 96 is fixedly connected to the support shaft 912 by a snap fastener. The side of the support shaft 912 is evenly provided with bracket 1 98. The inner side of bracket 1 98 is fixedly connected to the side of the support shaft 912. The inner side of bracket 1 98 is rotatably connected to bracket 2 99. The guide shaft 910 is slidably connected between bracket 1 98 and bracket 2 99. The support shaft 912 is fitted with spring 2 911. During the movement of the movable frame 96, the support shaft 912 drives bracket 1 98 and bracket 2 99 to move synchronously. The two brackets rely on the guide shaft 910 for guidance and the reset tension of spring 2 911 on the guide shaft 910 to rotate and unfold with the support shaft 912 as the fulcrum, which finally drives the flexible roller brush 97 to fully open. Roller brushes 97 are rotatably connected between the two brackets 98 and the two brackets 99. One end of spring 911 is fixedly connected to bracket 98, and the other end of spring 911 is fixedly connected to bracket 99. Cylinder 94 continuously drives the moving frame 96 to move as a whole. After unfolding, the roller brushes 97 on bracket 98 adhere to the inner surface of the lower pressure plate 61 and the outer wall of the ejector rod 67, and move synchronously with the moving frame 96 to thoroughly clean the inside of the cavity and the surface of the ejector rod 67, removing residual fine adhesive powder. The roller brushes 97 can be made of sponge material or flexible brush cylinder. After the roller brush 97 is unfolded, it is continuously driven by the cylinder 94 to move the moving frame 96. The bracket 98 and the bracket 99 remain unfolded, so that the roller brush 97 closely adheres to the inner wall of the lower pressure plate 61 and the surface of the ejector rod 67 to complete the cleaning of residual fine adhesive powder inside the lower pressure plate 61. The roller brush 97 can be made of sponge material or a flexible brush cylinder. At the same time, the upper heating plate 3 can be driven down to the appropriate position by the driving component 4, so that the roller brush 97 on the unfolded bracket 2 99 can be synchronously attached to the bottom of the upper heating plate 3, so as to realize the synchronous cleaning operation of the inner cavity of the lower pressure plate 61, the ejector rod 67, and the bottom of the upper heating plate 3. During cleaning, the negative pressure fan 72 inside the collection box 71 is started, and the negative pressure airflow is introduced into the air-cooled tank 63 through the collection pipe 73. After the plate is ejected, the ejector rod 67 moves upward, and its upper wide section separates from the upper wide groove area of ​​the ejector groove 64, while the lower narrow section of the rod remains in the groove. Since the upper wide slot of the top outlet slot 64 is connected to the air-cooling slot 63, under the traction of the negative pressure airflow, the debris and fine powder swept down from the inner cavity of the lower pressure plate 61 will enter the air-cooling slot 63 along the wide slot of the top outlet slot 64. Then, under the traction of the negative pressure airflow, the dust will be drawn through the air-cooling slot 63 at high speed, and then flow through the collection pipe 73 in sequence and finally be collected in the collection box 71. After the cleaning operation is completed, cylinder 1 94 drives the moving frame 96 to reset. Under the compression and limiting of the inner side wall of the lower pressure plate 61, bracket 1 98 and bracket 2 99 slide along the guide shaft 910 and compress spring 2 911 to achieve bidirectional retraction, driving the roller brush 97 to complete the storage and wait for the next operation. Specific workflow: Clean the cut and cleaned multi-layer eyeglass plates, remove surface dust and oil, align and stack them in layers, and place them in the pressing component 6. Start the drive component 4, which drives the upper heating plate 3 to move downward along the guide post 2 and slowly close the mold with the lower pressing component 6. The plate is pre-fixed by light pressure, and the air between the plate layers is discharged at the same time. While maintaining the mold closed state, the upper heating plate 3 continues to operate at a constant temperature, and the heat is evenly transferred to the board, which gradually softens the surface of the board and makes the interlayer contact surface meet the bonding requirements. During this process, the pressure holding action is performed simultaneously. Under constant temperature and pressure conditions, the layers of the board are tightly bonded together, and the bonding of the board is completed by the mutual penetration and fusion of polymer materials. After the pressure holding process is completed, maintain the pressure without releasing it, and start the water cooling component 8 to force-cool the pressure plate and the plate. Continue cooling until the overall temperature of the board drops below 50℃ to completely eliminate internal stress in the material and prevent problems such as springback, deformation, and delamination in the finished product; After the temperature reaches the target, the pressure is slowly released, the upper and lower pressure plates 61 automatically reset, and then the cleaning component 9 is activated to clean the lower pressure component 6. At the same time, the negative pressure collection component 7 is activated to collect the residual fine adhesive powder generated during cleaning. When performing water cooling operation, start water pump 84 to draw cold water from water cooling box 81 and continuously send it into water cooling pipe 82 of lower pressure plate 61. The water-cooled pipe 82 is fitted into the water-cooled tank 62. When the water flows in the pipe, it continuously removes the heat from the inside of the pressure plate 61 and the plate through heat exchange, thereby achieving cooling. At the same time, water pump 83 is started to continuously return the water that has completed heat exchange in water-cooled pipe 82 to water-cooled box 81, increase the overall water flow speed in the pipe, and further accelerate the cooling efficiency of the lower pressure plate 61. The water-cooled box 81 is equipped with a mesh plate frame 85 to filter the flowing water and intercept solid impurities in the water, so as to prevent impurities from being sucked into the water-cooled pipe 82 by the water pump 84 and causing pipe blockage. While the pressure plate 61 and the plate are being cooled by water, the negative pressure fan 72 in the collection box 71 is started. The fan generates negative pressure, which forms a directional airflow in the air-cooling groove 63 inside the pressure plate 61 through the collection pipe 73. The negative pressure gas drives the ventilation mechanism 65 in the air-cooled slot 63 to open, introducing outside air to form convection. Fresh outside air is continuously replenished into the inner space of the lower pressure plate 61 to form forced convection air cooling. The airflow directly cools the inner side of the lower pressure plate 61 and the plate material. The airflow flows along the surrounding air cooling grooves 63, washes the outer wall of the water cooling pipe 82, and assists in cooling the water cooling pipe 82, thereby greatly accelerating the overall cooling speed. Start the negative pressure fan 72 in the air collection box to continuously draw air from the air-cooled slot 63 of the lower pressure plate 61; The negative pressure causes the second round block 657 inside the ventilation pipe 651 to move. The second round block 657 pulls the first round block 655 through the round shaft 654, causing the first round block 655 to detach from the inside of the ventilation pipe 651. This allows outside air to continuously enter the air-cooled slot 63 inside the lower pressure plate 61 through the ventilation pipe 651, completing the ventilation and convection heat dissipation. The ventilation duct 651 adopts a structure that is wide at both ends and narrow in the middle. The narrow section in the middle is equipped with a spiral blade 652, which can guide the airflow entering from the outside in layers. Under normal pressure, spring 3 656 pushes round block 1 655 to press against the wide end of ventilation pipe 651, and at the same time, round block 2 is linked by round shaft 654 to close ventilation pipe 651, blocking external impurities from entering and preventing ventilation pipe 651 from becoming blocked. Once the pressure plate 61 and the internal sheet material have cooled down, cylinder 68 is activated. The output end of cylinder 68 pushes the ejector plate 66 to move upward in the inner cavity of the base 1, which in turn drives the ejector rod 67 on the ejector plate 66 to move upward along the corresponding ejector groove 64, thus ejecting the sheet material placed in the lower pressure plate 61 and realizing automatic material ejection, which facilitates material handling and unloading. After the material is removed, the upper heating plate 3 returns to its original position. The template on the side of the upper heating plate 3 releases the pressure on the baffle 92. The baffle 92 is reset upward along the inner side of the lower pressure plate 61 by the reset action of the sliding shafts 91 on both sides and the spring 93. After the material debris remaining on the inner side of the lower pressure plate 61 is blown away by the air gun, fine glue powder will still remain in the inner cavity of the lower pressure plate 61. Start cylinder 94. The output end of cylinder 94 drives the moving frame 96 to move, so that the moving frame 96 disengages from the inner edge of the lower pressure plate 61 and extends into the lower pressure plate 61. During the movement of the mobile frame 96, the support shaft 912 drives the bracket 1 98 and bracket 2 99 to move synchronously. The two brackets rely on the guide shaft 910 for guidance and the return tension of the spring 2 911 on the guide shaft 910 to rotate and unfold with the support shaft 912 as the fulcrum, which finally drives the flexible roller brush 97 to fully open. After the roller brush 97 is unfolded, it is continuously driven by the cylinder 94 to move the moving frame 96. The bracket 98 and the bracket 99 remain unfolded, so that the roller brush 97 closely adheres to the inner wall of the lower pressure plate 61 and the surface of the ejector rod 67 to clean the residual fine adhesive powder inside the lower pressure plate 61. The roller brush 97 can be made of sponge material or a flexible brush cylinder. At the same time, the upper heating plate 3 can be driven down to the appropriate position by the driving component 4, so that the roller brush 97 on the unfolded bracket 2 99 can be synchronously attached to the bottom of the upper heating plate 3, so as to realize the synchronous cleaning operation of the inner cavity of the lower pressure plate 61, the ejector rod 67, and the bottom of the upper heating plate 3. During cleaning, the negative pressure fan 72 inside the collection box 71 is started, and the negative pressure airflow is introduced into the air-cooled tank 63 through the collection pipe 73. After the plate is ejected, the ejector rod 67 moves upward, and its upper wide section separates from the upper wide groove area of ​​the ejector groove 64, while the lower narrow section of the rod remains in the groove. Since the upper wide slot of the top outlet slot 64 is connected to the air-cooling slot 63, under the traction of the negative pressure airflow, the fine adhesive powder swept down from the inner cavity of the lower pressure plate 61 will enter the air-cooling slot 63 along the wide slot of the top outlet slot 64, and then under the traction of the negative pressure airflow, it will flow through the collection pipe 73 in sequence and finally flow into the collection box 71 for centralized collection. After the cleaning operation is completed, cylinder 94 drives the moving frame 96 to reset. Under the compression and limiting of the inner side wall of the lower pressure plate 61, bracket 98 and bracket 99 slide along the guide shaft 910 and compress spring 911 to achieve bidirectional retraction, driving the roller brush 97 to complete the storage and wait for the next operation.

[0012] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
