Description

Technical Field

[0002] PET (polyethylene terephthalate) foamed board is a lightweight and high-strength material, commonly used in fields such as packaging, building insulation, and advertising displays. During the production process, in order to ensure product quality and performance, a cooling and transporting device is an essential link. The main function of this device is to rapidly cool the PET foamed board after extrusion molding and smoothly transport it from one station to another.

[0003] The existing methods for cooling foamed boards are usually air cooling or water cooling. Among them, air cooling cools the foamed board through the natural convection of air.

Although the water cooling method can complete the cooling process more quickly, water residues on the foamed board may leave marks on the surface of the board, such as water stains and spots, affecting the appearance quality. Moreover, during the transportation of the existing foamed boards, since the temperature of the foamed board is not completely cooled and formed and still maintains a certain viscosity, it is easy to adhere to the conveyor belt, affecting the overall transportation smoothness.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the embodiments of the present invention.

[0028] The following disclosure provides many different embodiments or examples for implementing different structures of the embodiments of the present invention. To simplify the disclosure of the embodiments of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the embodiments of the present invention.

[0029] The embodiment of the present invention provides a cooling and transporting device for producing PET foam boards, and the cooling and transporting device for producing PET foam boards is described in detail below. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0030] The embodiments of the present invention are described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figures 1 - 4 In the present embodiment, a cooling and transportation equipment for producing PET foam boards is provided, comprising: a box body 1, a partition 101 is installed inside the box body 1, the inside of the box body 1 is divided into a spray chamber and an air jet chamber by the partition 101, a first conveyor belt 202 is provided inside the spray chamber, a second conveyor belt 406 is provided inside the air jet chamber, and a cooling box 3 is provided outside the box body 1; a cooling component is arranged between the box body 1 and the cooling box 3, the cooling component comprises: a first water pump 303, a water spray pipe 305, an air jet pipe 701, an air pump 704 and a conduit 705, a straightening component is provided on the vibration block 4, the straightening component comprises: an adjustment box 6, a rotating rod 602, a limit plate 603 and an arc plate 606, a vibration component is provided between the box body 1 and the second conveyor belt 406, and the vibration component comprises: an equipment box 5, a servo motor 501, an eccentric wheel 502, a vibration block 4 and a base 404.

[0032] Among them, through the setting of the cooling component, the two methods of air cooling and water cooling are combined. After the foam plate is quickly cooled by water cooling, the air cooling is used to blow away the residual moisture on the foam plate and take away the residual preheating, thereby improving the cooling effect and effectively solving the problem of residual moisture on the foam plate. Secondly, through the setting of the vibration component, the second conveyor belt 406 can be slightly vibrated to avoid adhesion between the foam plate and the second conveyor belt 406, thereby ensuring smooth transportation, and cooperating with the setting of the straightening component to avoid position displacement of the foam plate after being vibrated, which affects the foam plate from entering the next process.

[0033] See also Figures 4 - 6 Two fixed blocks 2 are installed inside the spray chamber, two rotating rods 201 are rotatably connected between the two fixed blocks 2, a rotating motor 203 is installed on one side of the fixed block 2, and the rotating motor 203 is drivingly connected to one of the rotating rods 201, the first conveyor belt 202 is located between the two rotating rods 201, and a slot 102 is opened on the partition 101, and a connecting plate 103 is connected inside the slot 102.

[0034] During the production of the foaming board, it is necessary to cool and shape the foaming board. At this time, the extruded foaming board is sent into the spraying chamber and placed on the first conveyor belt 202. At this time, the rotating motor 203 drives the rotating rod 201 to rotate, thereby driving the first conveyor belt 202 to move, and moving the foaming board on the first conveyor belt 202 towards the air jet chamber. Then, through the settings of the slot 102 and the connecting plate 103, the foaming board on the first conveyor belt 202 can be smoothly sent onto the second conveyor belt 406.

[0035] Please refer to Figure 4 and Figure 9 As shown in, a first water pump 303 is provided inside the cooling box 3, multiple water spray pipes 305 are provided on the top of the first conveyor belt 202, multiple air spray pipes 701 are provided on the top of the second conveyor belt 406, an air extraction pump 704 is provided on the surface of the box body 1, a conduit 705 is connected between the air extraction pump 704 and the cooling box 3, a mounting plate 7 is installed inside the air jet chamber, multiple air spray pipes 701 are evenly distributed on the mounting plate 7, the tops of multiple air spray pipes 701 in the same column are all connected with a gas guide pipe 702, the top of the air extraction pump 704 is connected with an air delivery pipe 703, the top end of the air delivery pipe 703 is connected with the gas guide pipe 702, the top of the first water pump 303 is connected with a water delivery pipe 304, and the water delivery pipe 304 communicates with multiple water spray pipes 305. Multiple spray holes are provided at the bottom of the water spray pipes 305, and the second conveyor belt 406 is a mesh conveyor belt.

[0036] During the transportation of the foaming board on the first conveyor belt 202, the first water pump 303 inputs the cold water in the cooling box 3 into the water spray pipes 305 through the water delivery pipe 304, and sprays it out through the spray holes at the bottom of the water spray pipes 305 to perform spray water cooling on the foaming board on the first conveyor belt 202, so as to quickly take away the heat on the foaming board. Then, after the foaming board after spray cooling is sent onto the second conveyor belt 406, the air extraction pump 704 sucks in and compresses the external gas, and then conveys the compressed gas into multiple gas guide pipes 702 through the air delivery pipe 703, and then sprays it out through multiple air spray pipes 701 to perform air cooling on the foaming board on the second conveyor belt 406. By spraying out the high-pressure gas, on the one hand, the remaining heat on the foaming board can be taken away by the air flow, accelerating the cooling and forming efficiency of the foaming board. On the other hand, the residual water on the foaming board is blown away by the high-pressure air flow, and at the same time, the rapid flow of the gas can accelerate the evaporation efficiency of the water on the surface of the foaming board, which can reduce the water adhered to the foaming board and can also utilize the large amount of heat taken away when the water evaporates. The second conveyor belt 406 is a mesh conveyor belt to facilitate the dropping of water.

[0037] Please refer to Figure 8, wherein, a heat conducting plate 301 is installed inside the cooling box 3, and a plurality of uniformly distributed heat conducting fins 302 are installed on the heat conducting plate 301. A second water pump 306 is installed inside the cooling box 3. One side of the second water pump 306 is connected with a water suction pipe 307, and one end of the water suction pipe 307 extends into the spray cavity and the air jet cavity. The inside of the cooling box 3 is separated by the heat conducting plate 301 into two parts, namely a water storage cavity and a heat dissipation cavity.

[0038] Through the arrangement of the second water pump 306 and the water suction pipe 307, the accumulated water with heat at the bottom of the spray cavity and the air jet cavity can be pumped into the water storage cavity and then be pumped away by the first water pump 303 again for spraying, which is recycled and saves water resources. As time goes by, the water with heat is continuously pumped back, which causes the temperature of the cold water in the water storage cavity to rise, resulting in a decline in the cooling effect of the cold water on the foaming board. At this time, during the operation of the air extraction pump 704, part of the compressed gas is blown into the heat dissipation cavity of the cooling box 3 through the conduit 705. Then, through the arrangement of the heat conducting plate 301 and the heat conducting fins 302, the heat in the water can be conducted and dissipated into the heat dissipation cavity. At this time, the high-pressure gas blown out through the conduit 705 quickly takes away the heat inside the heat dissipation cavity. By accelerating the air flow rate near the heat conducting plate 301 and the heat conducting fins 302, the heat conduction and dissipation efficiency can be increased, so as to take away the heat of the cold water in the water storage cavity and ensure the cooling effect of the cold water on the foaming board.

[0039] Please refer to Figure 4 and Figure 7 , wherein, two vibration blocks 4 are arranged inside the air jet cavity. A device box 5 is installed on one side of the vibration block 4. A plurality of movable sleeves 401 are connected to the bottom of the vibration block 4. Two driving rods 405 are rotatably connected between the two vibration blocks 4. A driving motor 407 is installed on one side of one of the vibration blocks 4, and the driving motor 407 is drivingly connected to one of the driving rods 405.

[0040] After the foaming board is sent onto the second conveyor belt 406, the driving motor 407 drives the driving rod 405 to rotate, so that the second conveyor belt 406 moves to drive the foaming board to move inside the air jet cavity for air cooling.

[0041] Please refer to Figure 4 , Figure 7 and Figure 11 , wherein, a servo motor 501 is installed inside the device box 5. One side of the servo motor 501 is connected with a detachable eccentric wheel 502. The eccentric wheel 502 is located on the outer surface of the device box 5. An activity groove 402 is formed at the bottom of the movable sleeve 401. A plurality of activity springs 403 are connected inside the activity groove 402. A plurality of bases 404 corresponding to the positions of the movable sleeves 401 are installed inside the air jet cavity. The top end of the base 404 extends into the activity groove 402, and the bottom end of the activity spring 403 is connected to the base 404.

[0042] During the process of the foaming board cooling and forming, it is easy to adhere to the first conveyor belt 202 and the second conveyor belt 406. Since the first conveyor belt 202 is in the spraying chamber, the cold water sprayed down forms a water film on the surface of the first conveyor belt 202 to reduce the adhesion of the foaming board. When the foaming board is conveyed by the second conveyor belt 406, the eccentric wheel 502 is driven to rotate by the servo motor 501, and the centrifugal force generated when the eccentric wheel 502 rotates is used to realize the slight vibration of the vibration block 4 and the second conveyor belt 406. For the foaming board, the slight vibration can help the foaming board cool more evenly, avoid adhesion, and contribute to improving the conveying efficiency. Then, during the vibration of the vibration block 4, through the setting of the base 404 and the movable groove 402, the moving direction of the vibration block 4 can be limited. And through the setting of the movable spring 403, it can provide a movable space for the vibration of the vibration block 4, absorb and buffer the vibration at the same time, reduce the vibration transmitted to the box body 1, can reduce the overall noise level, and reduce the wear between mechanical components. When the eccentric wheel 502 stops rotating, the movable spring 403 can help the second conveyor belt 406 quickly return to the initial state to ensure that the foaming board moves forward smoothly.

[0043] Please refer to Figure 7 , wherein, an adjustment box 6 is connected to the top of the vibration block 4. An adjustment cavity 601 is opened inside the adjustment box 6. A through groove is opened on one side of the adjustment box 6 close to the second conveyor belt 406. A rotating rod 602 is rotatably connected inside the through groove. One end of the rotating rod 602 is rotatably connected to a limiting plate 603 through a bearing. An arc-shaped plate 606 connected to the rotating rod 602 is arranged inside the adjustment cavity 601. A positive and negative motor 608 is installed on the top of the adjustment box 6. The bottom of the positive and negative motor 608 is drivingly connected to a gear 607, and the gear 607 is located inside the adjustment cavity 601. Tooth teeth meshing with the gear 607 are arranged on the outer arc surface of the arc-shaped plate 606. One side of the limiting plate 603 is connected to a telescopic rod 604. A sliding groove 605 is opened on one side of the adjustment box 6. One end of the telescopic rod 604 extends into the sliding groove 605 and is connected to a slider.

[0044] During the transportation of the foaming board on the second conveyor belt 406, due to the slight vibration of the vibration block 4 and the second conveyor belt 406, it is inevitable that the position of the foaming board will be inclined or shifted. At this time, the positive and negative motor 608 drives the gear 607 to rotate, so that the gear 607 drives the arc plate 606 to move through the teeth, and then drives the rotating rod 602 to rotate. During the rotation of the rotating rod 602, the limiting plate 603 is driven to move on the second conveyor belt 406. Then, due to the setting of the telescopic rod 604, the slider and the chute 605, the limiting plate 603 always maintains a state parallel to the chute 605. At the same time, the chute 605 and the telescopic rod 604 both provide a moving space for the limiting plate 603, avoiding the movement interference when the rotating rod 602 drives the limiting plate 603 to move. Adjust the position of the limiting plate 603 according to the width of the cooled foaming board, so that during the transportation of the foaming board, it contacts the rotating rod 602 and moves towards the area of the limiting plate 603 along the direction of the rotating rod 602, and is straightened by the two parallel limiting plates 603, so as to facilitate the foaming board to be smoothly sent out of the box body 1 and enter the next process.

[0045] Working principle: During the production of the foaming board, it is necessary to cool and shape the foaming board. At this time, the extruded foaming board is sent into the spraying chamber and placed on the first conveyor belt 202. At this time, the rotating motor 203 drives the rotating rod 201 to rotate, and then drives the first conveyor belt 202 to move, moving the foaming board on the first conveyor belt 202 towards the air jet chamber. Then, through the setting of the slotted groove 102 and the connecting plate 103, the foaming board on the first conveyor belt 202 can be smoothly sent onto the second conveyor belt 406. After the foaming board is sent onto the second conveyor belt 406, the driving motor 407 drives the driving rod 405 to rotate, so that the second conveyor belt 406 moves to drive the foaming board to move inside the air jet chamber for air cooling.

[0046] During the transportation of the foaming board on the first conveyor belt 202, the first water pump 303 pumps the cold water in the cooling tank 3 into the water spray pipe 305 through the water supply pipe 304, and sprays it out through the spray holes at the bottom of the water spray pipe 305 to spray and water-cool the foaming board on the first conveyor belt 202, so as to quickly take away the heat on the foaming board. Then, after the foaming board that has been cooled by spraying is sent onto the second conveyor belt 406, the external gas is pumped in and compressed by the air extraction pump 704, and then the compressed gas is transported through the gas transmission pipe 703 into multiple air guide pipes 702, and then sprayed out through multiple air spray pipes 701 to air-cool the foaming board on the second conveyor belt 406. By spraying out the high-pressure gas, on the one hand, the remaining heat on the foaming board can be taken away by the air flow, accelerating the cooling and forming efficiency of the foaming board. On the other hand, the residual water on the foaming board is blown away by the high-pressure air flow, and at the same time, the rapid flow of the gas can accelerate the evaporation efficiency of the water on the surface of the foaming board, which can reduce the water attached to the foaming board and can also utilize the large amount of heat taken away when the water evaporates.

[0047] Through the setting of the second water pump 306 and the water extraction pipe 307, the accumulated water with heat at the bottom of the spray chamber can be pumped into the water storage chamber and then pumped away by the first water pump 303 for spraying again, which is recycled to save water resources. As time goes by, the continuously recycled water with heat makes the temperature of the cold water in the water storage chamber rise, resulting in a decline in the water-spraying and cooling effect of the cold water on the foaming board. At this time, during the operation of the air extraction pump 704, part of the compressed gas is blown into the heat dissipation chamber of the cooling tank 3 through the conduit 705. Then, through the setting of the heat conduction plate 301 and the heat conduction sheet 302, the heat in the water can be conducted and dissipated into the heat dissipation chamber. At this time, the high-pressure gas blown out through the conduit 705 quickly takes away the heat inside the heat dissipation chamber. By accelerating the air flow rate near the heat conduction plate 301 and the heat conduction sheet 302, the heat conduction and dissipation efficiency can be accelerated, so as to take away the heat of the cold water in the water storage chamber and ensure the water-spraying and cooling effect of the cold water on the foaming board.

[0048] During the process of the foamed board cooling and forming, it is likely to adhere to the first conveyor belt 202 and the second conveyor belt 406. Since the first conveyor belt 202 is in the spraying chamber, the cold water sprayed forms a water film on the surface of the first conveyor belt 202 to reduce the adhesion of the foamed board. When the foamed board is conveyed on the second conveyor belt 406, the eccentric wheel 502 is driven to rotate by the servo motor 501, and the centrifugal force generated during the rotation of the eccentric wheel 502 is used to achieve slight vibration of the vibration block 4 and the second conveyor belt 406. For the foamed board, slight vibration can help the foamed board cool more evenly, avoid adhesion, and contribute to improving the conveying efficiency. Then, during the vibration of the vibration block 4, through the settings of the base 404 and the movable groove 402, the moving direction of the vibration block 4 can be limited. And through the setting of the movable spring 403, it can provide a movable space for the vibration of the vibration block 4, absorb and buffer the vibration at the same time, reduce the vibration transmitted to the box body 1, can reduce the overall noise level, and reduce the wear between mechanical components. When the eccentric wheel 502 stops rotating, the movable spring 403 can help the second conveyor belt 406 quickly return to the initial state to ensure that the foamed board moves forward smoothly.

[0049] During the process of the foamed board being conveyed on the second conveyor belt 406, due to the slight vibration of the vibration block 4 and the second conveyor belt 406, it is inevitable that the position of the foamed board will be tilted or shifted. At this time, the positive and negative motor 608 drives the gear 607 to rotate, so that the gear 607 drives the arc-shaped plate 606 to move through the teeth, and then drives the rotating rod 602 to rotate. During the rotation of the rotating rod 602, the limiting plate 603 is driven to move on the second conveyor belt 406. Then, due to the settings of the telescopic rod 604, the slider and the sliding groove 605, the limiting plate 603 always maintains a state parallel to the sliding groove 605. At the same time, both the sliding groove 605 and the telescopic rod 604 provide a movable space for the limiting plate 603 to avoid motion interference when the rotating rod 602 drives the limiting plate 603 to move. Adjust the position of the limiting plate 603 according to the width of the cooled foamed board, so that during the conveying process of the foamed board, it contacts the rotating rod 602 and moves towards the area of the limiting plate 603 along the orientation of the rotating rod 602, and is straightened by the two parallel limiting plates 603, so as to facilitate the foamed board to be smoothly sent out of the box body 1 and enter the next process.
