Description

Technical Field

[0001] This utility model relates to the field of thermosetting composite board processing technology, and in particular to a circulating water-cooled leveling device for thermosetting composite boards. Background Technology

[0002] Thermosetting composite board leveling devices are specialized equipment used on thermosetting composite board production lines to correct warping and wrinkles in the boards, ensuring surface flatness and structural stability. They correct deformation through pressure rollers or scrapers. Some devices incorporate hot air technology, using high-temperature air to optimize the material's mechanical properties and assist in leveling. They are adaptable to boards of different thicknesses, and some are equipped with limiting and buffer components to reduce damage. They are widely used in the processing of resin-based and fiber-reinforced thermosetting composite boards, improving board strength and appearance quality while reducing production losses.

[0003] However, the resin base is difficult to cool quickly during leveling, which means that the leveled board needs to wait a long time to cool before it can enter the next process, significantly extending the overall production cycle and reducing processing efficiency. Slow cooling can also cause the resin base to undergo secondary deformation due to external forces before it is fully set, resulting in a rebound in the flatness of the board and increasing the defect rate. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where the resin base is difficult to cool quickly during leveling, which leads to the need for the leveled board to wait for a long time to cool before entering the next process, significantly extending the overall production cycle, reducing processing efficiency, and the slow cooling makes the resin base prone to secondary deformation under external force before it is fully set, resulting in a rebound in the flatness of the board and an increase in the defect rate. The proposed thermosetting composite board circulating water cooling leveling device addresses these issues.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a circulating water-cooled leveling device for thermosetting composite panels, comprising a flat plate, support legs, and a leveling device. The support legs are fixed to the lower surface of the flat plate, and the leveling device is disposed on the upper surface of the flat plate. The leveling device includes a slider, which is slidably connected to the flat plate. An assembly is fixedly connected to the upper surface of the slider, and an air bladder is fixedly connected to the inner wall of the assembly. A pressure roller is rotatably connected to one end of the slider. The pressure roller is hollow, and a spray nozzle is opened on the surface of the pressure roller. The air bladder communicates with the pressure roller. A cylinder is fixedly connected to the upper surface of the assembly. A push plate is fixedly connected to the lower surface of the airbag, and the push plate is slidably connected to the assembly. The upper surface of the airbag is fixedly connected to the push plate. By setting a flattening device, the unevenness problems such as warping and protrusion of the composite board are effectively eliminated, ensuring the flattening accuracy of the board. It can also achieve flexible switching between water cooling and air cooling through the cooperation of the airbag, water pipe and cylinder. When there is water, the water is delivered to the pressure roller and sprayed on the surface of the composite board by pressure, which quickly reduces the temperature of the resin base and shortens the production cycle. When there is no water, it switches to air cooling to continue auxiliary cooling, adapting to different working conditions. At the same time, the cooling process is carried out simultaneously with the flattening, without the need to add an extra cooling process, thus improving the overall processing efficiency.

[0006] Preferably, the airbag has a connection port on one side, and there are two sliders. The two sliders are respectively set at both ends of the pressure roller. By setting the pressure roller, it moves along the surface of the composite board with the slider under the drive of the motor. The rolling action directly acts on the composite board, which can effectively eliminate unevenness problems such as warping and protrusion of the board, flatten the board, and ensure the flatness accuracy of the composite board.

[0007] Preferably, one end of the slider is fixedly connected to a motor, and the drive end of the motor is fixedly connected to a gear. By setting the motor, the gear is driven to rotate, and the gear will drive the slider to move along the rack. During the movement of the slider, the pressure roller will move synchronously, so that the pressure roller can perform a rolling operation along the surface of the composite board placed on the flat plate. This, in conjunction with the flattening device, realizes the flattening operation of the composite board. This lays the foundation for subsequent water cooling or air cooling of the composite board through the cooperation of airbags, water pipes, and cylinders, and for fixing the composite board with fastening components to improve the flattening consistency. This ensures that the flattening process is carried out in an orderly manner to eliminate unevenness problems such as warping and protrusion of the composite board.

[0008] Preferably, a rack is fixedly connected to one end of the flat plate near the gear. The gear meshes with the rack. By setting the rack, when the motor drives the gear to rotate, the gear moves along the tooth surface of the rack, thereby driving the slider connected to the gear to move stably. This causes the slider to drive the pressure roller to move smoothly along the extension direction of the rack, ensuring that the pressure roller can perform rolling and flattening operations evenly and orderly along the surface of the composite board. This provides a stable moving guide for the flattening device to effectively eliminate unevenness problems such as warping and protrusion of the composite board.

[0009] Preferably, the surface of the flat plate is provided with a fastening assembly, which includes a bracket. The bracket is fixedly connected to the flat plate, and a guard rod is fixedly connected to the upper surface of the bracket. The surface of the guard rod has a threaded hole. A limiting plate is slidably connected to the surface of the bracket, and a threaded rod is threadedly connected to the surface of the guard rod. By setting the fastening assembly, after the composite plate is placed, the threaded rod can be rotated to drive the limiting plate to press down and fix the plate. This can effectively reduce the shaking or displacement of the composite plate during the leveling process caused by the pressure roller rolling and slight shrinkage during cooling, ensuring that the pressure roller always rolls along the preset path and improving the leveling consistency.

[0010] Preferably, the lower surface of the threaded rod is rotatably connected to the limiting plate, and the lower surface of the limiting plate is provided with locking teeth. By setting the threaded rod, after the composite plate is placed on the flat plate, the threaded rod is rotated to generate axial displacement under the cooperation of its own thread structure, thereby squeezing the limiting plate, pushing the limiting plate to move downward and contact the surface of the composite plate. The pressure transmitted during the rotation of the threaded rod makes the limiting plate tightly press the composite plate, thereby fixing the position of the composite plate.

[0011] Preferably, the threaded rod is located directly above the limiting plate, and the bracket and guard rod are arranged in a "U" shape.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a flattening device, during use, the composite board is placed flat on a flat plate, and then a water pipe is connected to the connection port. The motor is started, and the motor drives the gear to rotate. The gear drives the slider along the rack to move, and the slider moves while driving the pressure roller to flatten the surface of the composite board. Simultaneously, water is injected into the air chamber through the water pipe, and the cylinder drives the push plate to squeeze the air chamber. Under pressure, the water in the air chamber flows into the pressure roller and is discharged through the spray nozzle, spraying onto the surface of the composite board to accelerate cooling. When there is no water, the cylinder squeezes the air chamber, air enters through the connection port, and under the action of the piston... Air is drawn into the pressure roller and sprayed out through the spray nozzle, replacing water cooling with air cooling. By setting up a flattening device, unevenness problems such as warping and protrusion of the composite board are effectively eliminated, ensuring the flattening accuracy of the board. It can also achieve flexible switching between water cooling and air cooling through the cooperation of airbags, water pipes and cylinders. When water is available, water is delivered to the pressure roller and sprayed on the surface of the composite board using pressure, which quickly reduces the temperature of the resin base and shortens the production cycle. When there is no water, it switches to air cooling to continue auxiliary cooling, adapting to different working conditions. At the same time, the cooling process is carried out simultaneously with the flattening, without the need for additional cooling steps, thus improving the overall processing efficiency.

[0014] 2. In this utility model, by setting a fastening component, when the composite plate is placed on the flat plate, the threaded rod is rotated. While the threaded rod is rotating, it squeezes the limiting plate. The limiting plate moves downward and presses down on the composite plate, preventing the composite plate from shaking during processing. By setting a fastening component, after the composite plate is placed, the threaded rod can be rotated to drive the limiting plate to squeeze downward and fix the plate. This can effectively reduce the shaking or displacement of the composite plate caused by the pressure roller rolling and slight shrinkage during cooling during the leveling process, ensuring that the pressure roller always rolls along the preset path and improving the leveling consistency.

[0021] Please see Figures 1-5 This utility model provides a technical solution: a circulating water-cooled leveling device for thermosetting composite panels, including a flat plate 1, support legs 2 and a flattening device 3. The support legs 2 are fixed on the lower surface of the flat plate 1, and the flattening device 3 is set on the upper surface of the flat plate 1.

[0022] In this embodiment: the flattening device 3 includes a slider 32, which is slidably connected to the plate 1. A mounting bracket 33 is fixedly connected to the upper surface of the slider 32. An air bladder 35 is fixedly connected to the inner wall of the mounting bracket 33. A pressure roller 31 is rotatably connected to one end of the slider 32. The pressure roller 31 is hollow and has spray nozzles on its surface. The air bladder 35 communicates with the pressure roller 31. A cylinder 37 is fixedly connected to the upper surface of the mounting bracket 33. A push plate 36 is fixedly connected to the lower surface of the cylinder 37. The push plate 36 is slidably connected to the mounting bracket 33. The upper surface of the air bladder 35... Fixedly connected to the push plate 36, the flattening device 3 effectively eliminates unevenness problems such as warping and protrusion of the composite board, ensuring the flattening accuracy of the board. It can also achieve flexible switching between water cooling and air cooling through the cooperation of airbag 35, water pipe and cylinder 37. When there is water, the water is delivered to the pressure roller 31 and sprayed on the surface of the composite board by pressure, which quickly reduces the temperature of the resin base and shortens the production cycle. When there is no water, it switches to air cooling to continue to assist in cooling, adapting to different working conditions. At the same time, the cooling process is carried out simultaneously with the flattening, without the need to add an extra cooling process, thus improving the overall processing efficiency.

[0023] Specifically, the airbag 35 has a connection port 311 on one side, and there are two sliders 32. The two sliders 32 are respectively set at both ends of the pressure roller 31. By setting the pressure roller 31, it moves along the surface of the composite board with the slider 32 under the drive of the motor 39. The rolling action directly acts on the composite board, which can effectively eliminate unevenness problems such as warping and protrusion of the board, flatten the board, and ensure the flatness accuracy of the composite board.

[0024] Specifically, a motor 39 is fixedly connected to one end of the slider 32, and a gear 38 is fixedly connected to the drive end of the motor 39. By setting the motor 39, the gear 38 is driven to rotate, and the gear 38 will drive the slider 32 to move along the rack 310. During the movement of the slider 32, the pressure roller 31 will move synchronously, so that the pressure roller 31 can perform a rolling operation along the surface of the composite board placed on the flat plate 1. This, together with the flattening device 3, realizes the flattening operation of the composite board. This lays the foundation for the subsequent water cooling or air cooling of the composite board through the cooperation of the airbag 35, water pipe and cylinder 37, and for the fixing of the composite board through the fastening component 34 to improve the flattening consistency. This ensures that the flattening process is carried out in an orderly manner to eliminate unevenness problems such as warping and protrusion of the composite board.

[0025] Specifically, a rack 310 is fixedly connected to one end of the plate 1 near the gear 38. The gear 38 meshes with the rack 310. By setting the rack 310, when the motor 39 drives the gear 38 to rotate, the gear 38 moves along the tooth surface of the rack 310, thereby driving the slider 32 connected to the gear 38 to move stably. In turn, the slider 32 drives the pressure roller 31 to move smoothly along the extension direction of the rack 310, ensuring that the pressure roller 31 can perform rolling and flattening operations evenly and orderly along the surface of the composite board. This provides a stable moving guide for the flattening device 3 to effectively eliminate unevenness problems such as warping and protrusion of the composite board.

[0026] Specifically, the surface of the plate 1 is provided with a fastening component 34, which includes a bracket 341. The bracket 341 is fixedly connected to the plate 1. A guard rod 344 is fixedly connected to the upper surface of the bracket 341. A threaded hole is opened on the surface of the guard rod 344. A limiting plate 342 is slidably connected to the surface of the bracket 341. A threaded rod 343 is threadedly connected to the surface of the guard rod 344.

[0027] In this embodiment: by setting fastening component 34, after the composite plate is placed, the threaded rod 343 can be rotated to drive the limiting plate 342 to press down and fix the plate. This can effectively reduce the shaking or displacement of the composite plate caused by the pressure roller 31 rolling and slight shrinkage during cooling during the leveling process, and ensure that the pressure roller 31 always rolls along the preset path, thus improving the leveling consistency.

[0028] Specifically, the lower surface of the threaded rod 343 is rotatably connected to the limiting plate 342, and the lower surface of the limiting plate 342 is provided with locking teeth.

[0029] In this embodiment: by setting a threaded rod 343, after the composite plate is placed on the flat plate 1, by rotating the threaded rod 343, it generates axial displacement under the cooperation of its own thread structure, thereby squeezing the limiting plate 342, pushing the limiting plate 342 to move downward and contact the surface of the composite plate, and using the pressure transmitted during the rotation of the threaded rod 343 to make the limiting plate 342 press the composite plate tightly, thereby fixing the position of the composite plate.

[0030] Specifically, the threaded rod 343 is located directly above the limiting plate 342, and the bracket 341 and the guard rod 344 are arranged in a "U" shape.

[0031] Working principle: By setting up the flattening device 3, during use, the composite board is placed flat on the plate 1, and then a water pipe is connected to the connection port 311. The motor 39 is started, driving the gear 38 to rotate. The gear 38 moves along the rack 310, causing the slider 32 to move. Simultaneously, the slider 32 moves, causing the pressure roller 31 to flatten and roll the composite board surface. While water is injected into the airbag 35 through the water pipe, the cylinder 37 drives the push plate 36 to squeeze the airbag 35. Under pressure, the water in the airbag 35 flows into the pressure roller 31 and is discharged through the spray nozzle onto the surface of the composite board, accelerating its cooling. When there is no water, the cylinder 37 squeezes the airbag 35, and the connection port... Air enters through 311, and under the action of the piston, the air is driven into the pressure roller 31. The air is sprayed out through the spray nozzle, and air cooling replaces water cooling. By setting up the flattening device 3, the unevenness problems such as warping and protrusion of the composite board are effectively eliminated, ensuring the flattening accuracy of the board. It can also achieve flexible switching between water cooling and air cooling through the cooperation of air bag 35, water pipe and cylinder 37. When there is water, water is delivered to the pressure roller 31 and sprayed on the surface of the composite board by pressure, which quickly reduces the temperature of the resin base and shortens the production cycle. When there is no water, it switches to air cooling to continue auxiliary cooling, adapting to different working conditions. At the same time, the cooling process is carried out simultaneously with the flattening, without the need to add an extra cooling process, thus improving the overall processing efficiency.

[0032] By setting the fastening component 34, when the composite plate is placed on the flat plate 1, the threaded rod 343 is rotated. As the threaded rod 343 rotates, it presses the limiting plate 342. The limiting plate 342 moves downward and presses down on the composite plate, preventing the composite plate from shaking during processing. By setting the fastening component 34, after the composite plate is placed, the threaded rod 343 can be rotated to drive the limiting plate 342 to press down and fix the plate. This can effectively reduce the shaking or displacement of the composite plate caused by the pressure roller 31 rolling and slight shrinkage during cooling during the leveling process, ensuring that the pressure roller 31 always rolls along the preset path and improving the leveling consistency.
