A number of parallel feeding roller shafts are arranged between the two support rods, and feeding roller cylinders are provided on the feeding roller shafts.

[0004] Regarding the above related technologies, the inventor believes that there are the following defects: during the process of sizing the PVC raw material extruded by the double screw on the sizing table, the high-temperature melt will shrink during the cooling process, so it is easy to cause pits on the surface of the sized sheet, affecting the subsequent steps and thus affecting the quality of the final foamed board. Summary of the Invention

[0005] A sizing table applied to a foamed board production line provided by the present application adopts the following technical solutions:

[0006] A sizing table applied to a foamed board production line includes a workbench and a sizing plate provided on the workbench;

[0007] A leveling assembly is provided on the lower surface of the sizing plate;

[0008] The leveling assembly includes at least one leveling roller and a driving assembly for driving the leveling roller to move;

[0009] The length direction of the leveling roller is the same as the width direction of the sizing plate. The leveling roller is located below the sizing plate and can roll along the length direction of the sizing plate.

[0010] By adopting the above technical solution, the leveling roller in the leveling component can level the surface of the material during the rolling process, so that there are no protrusions or depressions on the surface of the material, and thus there are no pits on the surface of the cooled foaming board, which can improve the quality of shaping.

[0011] Optionally, a top plate is further provided above the shaping plate. The top plate is supported on the workbench through support legs, and a plurality of cylinders are fixedly connected to the upper surface of the top plate. The cylinders can drive the shaping plate to move up and down;

[0012] The driving component is installed on the top plate.

[0013] By adopting the above technical solution, the multiple cylinders can cooperate with each other to more stably control the up and down movement of the shaping plate, so that the shaping plate will not generate lateral movement, thereby preventing the shaping plate from causing wrinkles to the material.

[0014] Optionally, support plates are provided at both ends of the leveling roller. Connecting shafts are fixedly connected to both ends of the leveling roller, and the end of the connecting shaft far away from the leveling roller is rotatably connected to the support plate;

[0015] The upper end of the support plate is slidably connected to both sides in the length direction of the top plate, and the leveling roller is rotatably connected to the lower end of the support plate.

[0016] By adopting the above technical solution, the support plate can enable the leveling roller to be slidably installed on the top plate, thus facilitating the movement of the leveling roller.

[0017] Optionally, the driving component includes a driving motor installed on the support plate and a gear rotatably installed on the support plate;

[0018] Guide grooves are formed on both sides of the support plate, racks are fixedly connected to the bottom surfaces of the guide grooves, the gear is located in the guide groove, and the gear meshes with the rack;

[0019] The output shaft of the driving motor passes through the support plate and is coaxially fixedly connected to the gear;

[0020] The inside of the support plate is hollow, the end of the connecting shaft far away from the leveling roller extends into the inside of the support plate, and pulleys are coaxially fixedly connected to the end of the connecting shaft and the output shaft of the driving motor, and a belt is sleeved on the two pulleys.

[0021] By adopting the above technical solution, the driving motor can drive both the gear and the leveling roller to rotate simultaneously. Therefore, the driving gear can roll on the rack, thereby driving the support plate to move, and at the same time, it can also drive the leveling roller to rotate self - directionally, which is convenient and fast.

[0022] Optionally, two through - grooves are formed on the circumferential surface of the leveling roller. The length direction of the through - grooves is parallel to the axis of the leveling roller, and the through - grooves do not penetrate through both ends of the leveling roller;

[0023] A plurality of pressing rollers are provided in each through groove, the peripheral surface of the pressing roller protrudes from the peripheral surface of the leveling roller, and the axial direction of the pressing roller is perpendicular to the axial direction of the leveling roller;

[0024] A single - rotation reciprocating screw is inserted through the axis of the leveling roller, and both ends of the single - rotation reciprocating screw pass through the connecting shaft and the support plate and are fixedly connected;

[0025] The through groove extends in the depth direction to the position of the single - rotation reciprocating screw, so that the single - rotation reciprocating screw is exposed in the through groove. An arc - shaped plate is provided in the through groove, and the arc - shaped plate is in threaded cooperation with the single - rotation reciprocating screw, and the arc - shaped plate can reciprocate along the length direction of the through groove;

[0026] Limit grooves are also opened on both sides of the through groove, both sides of the arc - shaped plate are located in the limit grooves, and the arc - shaped plate is connected to the pressing roller.

[0027] By adopting the above - mentioned technical solution, the pressing roller protrudes from the surface of the leveling roller, and the rotation direction of the pressing roller is perpendicular to the rotation direction of the leveling roller. Therefore, during the process of the leveling roller leveling the material, the pressing roller can also level the material, and the leveling directions of the leveling roller and the pressing roller are perpendicular to each other. Furthermore, the material can be leveled from different directions, improving the leveling effect. The single - rotation reciprocating screw does not rotate with the leveling roller, but the arc - shaped plate can rotate with the leveling roller. Therefore, the arc - shaped plate can reciprocate on the single - rotation reciprocating screw, and the rotation of the leveling roller can also drive the movement of the pressing roller, without the need for an additional driving device, which is simpler and more convenient.

[0028] Optionally, a support rod is fixedly connected to the side of the arc - shaped plate away from the single - rotation reciprocating screw, and a moving plate is fixedly connected to the end of the support rod away from the arc - shaped plate. A plurality of pressing rollers are all embedded in the moving plate.

[0029] By adopting the above - mentioned technical solution, the cooperation between the moving plate and the arc - shaped plate can better drive the pressing roller to move, and at the same time, it will not affect the rotation of the pressing roller.

[0030] Optionally, the pressing roller is spindle - shaped.

[0031] By adopting the above - mentioned technical solution, the surface of the spindle - shaped pressing roller is a smooth curved surface both longitudinally and transversely. Therefore, the part of the pressing roller that protrudes from the peripheral surface of the leveling roller will not form a stepped surface, so the rotation of the leveling roller will not cause scratches on the surface of the material by the pressing roller.

[0032] Optionally, a cooling box is also provided at one end of the shaping plate. The inside of the leveling roller is hollow and filled with pure water. The leveling roller can enter the cooling box to freeze the pure water.

[0033] By adopting the above technical solution, the pure water inside the leveling roller freezes, enabling the leveling roller to maintain a relatively low temperature during operation. Therefore, during the leveling process, the material can be preliminarily shaped, preventing excessive shrinkage during subsequent shaping of the material and reducing the probability of pits on the surface of the foamed board after shaping.

[0034] Optionally, at one end of the shaping plate close to the cooling box, there are also two guiding rails. One end of each guiding rail is fixedly connected to the shaping plate, and the other end of each guiding rail tilts upward and extends into the cooling box.

[0035] The guiding rails communicate with the guiding grooves, and the racks in the guiding grooves extend out of the guiding grooves and extend on the guiding rails.

[0036] By adopting the above technical solution, under the action of the guiding rails, the leveling roller can enter and exit the cooling box, so that after the pure water inside the leveling roller melts, it can enter the cooling box for freezing.

[0037] In summary,

[0038] 1. The leveling roller can level the material on the workbench, making the surface of the material smoother, and thus reducing the probability of pits on the surface of the foamed board after shaping;

[0039] 2. The gear in the driving assembly can move on the rack, driving the leveling roller to move as a whole. While the driving motor drives the gear to roll on the rack, it can also drive the leveling roller to rotate through the belt pulley and belt. Therefore, the structure of the driving assembly is simpler and more convenient for subsequent maintenance;

[0040] 3. There are also multiple pressing rollers on the leveling roller. The pressing rollers can also level the material, and the leveling direction of the pressing rollers is perpendicular to that of the leveling roller. Therefore, the leveling effect can be improved. The pressing rollers are spindle-shaped, so that the protruding parts of the pressing rollers will not form stepped surfaces, and thus the pressing rollers will not scratch the material.

[0048] The following further elaborates on this application in conjunction with the attached Figures 1-5 drawings for a more detailed description.

[0049] A foamed board production line generally includes a crushing device, a grinding device, a powder mixing device, a twin - screw extruder, a shaping table, a tractor, and a cutting machine, which are connected in sequence. The crushing device and the grinding device crush and grind the raw materials for the foamed board to make the particle size of the raw materials reach the required mesh number. After the powder materials are mixed by the powder mixing device, they enter the twin - screw extruder, melt in the twin - screw extruder and then are extruded, and then flow onto the shaping table for shaping. After shaping, they are pulled by the tractor into the cutting machine for cutting. The cutting machine cuts the irregularly shaped foamed board after shaping into regular and appropriately sized shapes.

[0050] An embodiment of this application discloses a shaping table applied to a foamed board production line. Referring to Figure 1 , the shaping table includes a workbench 1 and a shaping plate 2 provided on the workbench 1. A water inlet pipe 11 and a water outlet pipe 12 are fixedly connected to the side wall of the workbench 1, which can supply cooling water into the workbench 1 to keep the workbench 1 in a low - temperature state. After the material extruded by the twin - screw extruder flows onto the shaping table, the shaping plate 2 moves downward. The shaping plate 2 presses the material on the workbench 1, enabling the material to be cooled and shaped, and the shaping plate 2 presses the material thinner so that the thickness of the cooled foamed board is the required thickness dimension.

[0051] Referring to Figure 1 and Figure 2 , above the shaping plate 2 is provided a top plate 3. The top plate 3 is connected to the workbench 1 through support legs 31, so that the top plate 3 can be installed on the workbench 1. A plurality of vertically downward cylinders 32 are fixedly connected to the upper surface of the top plate 3. The plurality of cylinders 32 are evenly distributed. The end of the telescopic rod of the cylinder 32 passes downward through the top plate 3 and is fixedly connected to the shaping plate 2. Therefore, the cylinder 32 can control the lifting of the shaping plate 2.

[0052] Referring to Figure 1 and Figure 2 below the sizing plate 2, a leveling assembly is further provided, and the leveling assembly includes a leveling roller 4 and a driving assembly 5 for driving the leveling roller 4 to move and rotate; the length direction of the leveling roller 4 is the same as the length direction of the sizing plate 2, and the leveling roller 4 can move along the length direction of the sizing plate 2 under the action of the driving assembly 5, and the leveling roller 4 can also rotate during the movement. During the movement and rotation of the leveling roller 4, the surface of the material moved onto the workbench 1 can be leveled, so that the surface of the material will not produce uneven shapes, thereby reducing the problem of protrusions or depressions on the surface of the material after cooling and contraction, and making the surface of the material smoother.

[0053] Referring to Figure 2 and Figure 3 the driving assembly 5 includes a support plate 51 and a driving motor 52 installed on the support plate 51; the number of support plates 51 is two, the number of driving motors 52 is one, and the driving motor 52 is installed on one support plate 51. The two support plates 51 are respectively located on both sides of the length direction of the top plate 3, and both ends of the leveling roller 4 are rotatably connected to the two support plates 51, so that the leveling roller 4 can rotate along its own axis.

[0054] Referring to Figure 2 and Figure 3 on both sides of the length direction of the top plate 3, T-shaped guide grooves 33 are provided, the guide grooves 33 are opened along the length direction of the top plate 3, a rack 34 is fixedly connected to the bottom surface of the guide grooves 33, a gear 53 is installed on the side wall of the support plate 51 close to the top plate 3, the gear 53 is located in the guide groove 33 and meshes with the rack 34, and the output shaft of the driving motor 52 passes through the support plate 51 and is coaxially fixedly connected to the gear 53. Therefore, the driving motor 52 can make the gear 53 move on the rack 34, so that the support plate 51 can move along the length of the top plate 3, and thus can drive the leveling roller 4 to move.

[0055] Referring to Figure 2 and Figure 3 the support plate 51 is hollow inside, the output shaft of the driving motor 52 passes through the cavity inside the support plate 51, both ends of the leveling roller 4 are fixedly connected with connecting shafts 41, the connecting shafts 41 are rotatably connected to the support plate 51, and at the same time, the ends of the connecting shafts 41 extend into the inside of the support plate 51. Belt pulleys 42 are sleeved on the parts of the driving motor 52 and the connecting shafts 41 located inside the support plate 51, and a belt 43 for linking the two belt pulleys 42 is sleeved on the two belt pulleys 42. Therefore, when the driving motor 52 rotates the gear 53, it can also drive the leveling roller 4 to rotate through the belt 43 and the belt pulleys 42.

[0056] Referring to Figure 2 and Figure 3, through the connection of the support plate 51, the driving motor 52 can drive the leveling roller 4 to move and rotate simultaneously, which can reduce the complexity of the driving component and facilitate the subsequent maintenance of the driving component.

[0057] Refer to Figure 2 and Figure 3 , a cooling cavity 44 is provided inside the leveling roller 4, and pure water is filled inside the cooling cavity 44. One end of the workbench 1 is provided with a cooling box 6, and a refrigerator is provided inside the cooling box 6. The leveling roller 4 can move into the cooling box 6 and can stay in the cooling box 6. Then the cooling box 6 can freeze the pure water inside the leveling roller 4 into ice. Therefore, during the process of leveling the material by the leveling roller 4, the temperature of the leveling roller 4 is relatively low. Therefore, the leveling roller 4 can preliminarily shape the material. When the material is shaped subsequently, the temperature difference is small and there will be no excessive shrinkage, so that the surface of the material will not have excessive deformation, improving the leveling effect.

[0058] Refer to Figure 2 and Figure 3 , the cooling box 6 stands on the ground through the support column 61, so that the bottom surface of the cooling box 6 is higher than the upper surface of the shaping plate 2, and it will not affect the connection between the shaping table and the front and rear equipment. The cooling box 6 and the top plate 3 are connected through the guide rail 62. The end of the rack 34 extends out of the guide groove 33 and extends along the guide rail 62 into the cooling box 6. Therefore, the leveling roller 4 can enter the cooling box 6 under the guidance of the guide rail 62 for cooling.

[0059] Refer to Figure 2 and Figure 3 , an inlet 63 is provided on one side of the cooling box 6 close to the workbench 1. A baffle 64 is hinged on the side wall at the inlet 63. The hinge point of the baffle 64 and the cooling box 6 is the upper end of the baffle 64. A rectangular hole 641 through which the guide rail 62 can pass is provided on the baffle 64. When the leveling roller 4 enters and exits the cooling box 6, the leveling roller 4 itself can push open the baffle 64. When the leveling roller 4 no longer exerts force on the baffle 64, the baffle 64 can return to its original position under its own gravity, without the need for other structures to control the opening and closing of the baffle 64, which is convenient and fast.

[0060] Refer to Figure 2 and Figure 3 , two inclined connecting plates 65 are fixedly connected to one side of the cooling box 6 close to the top plate 3. The end of the connecting plate 65 far from the cooling box 6 is fixedly connected to the top plate 3; the connecting plate 65 and the support leg 31 are respectively located at both ends of the top plate 3, so that there is no support leg 31 under the end of the top plate 3 close to the cooling box 6 to hinder the leveling roller 4 from entering the cooling box 6, enabling the leveling roller 4 to enter and exit the cooling box 6 normally.

[0061] Refer to Figure 4 and Figure 5, two symmetrical through grooves 45 are formed in the leveling roller 4. The length direction of the through groove 45 is the same as the axis direction of the leveling roller 4, and the through groove 45 does not penetrate through both ends of the leveling roller 4. Two moving plates 7 are arranged in the through groove 45. A plurality of pressing rollers 71 are embedded in the moving plate 7, and the axis direction of the pressing roller 71 is perpendicular to the axis direction of the leveling roller 4. The pressing roller 71 can rotate along its own axis; the moving plate 7 can move in the through groove 45 along the length direction of the through groove 45. Therefore, when the leveling roller 4 moves, the moving plate 7 also moves, and the moving direction is perpendicular to the moving direction of the leveling roller 4. Therefore, a plurality of pressing rollers 71 can also move, and the plurality of pressing rollers 71 can also level the material, and the leveling direction of the pressing roller 71 is perpendicular to the leveling direction of the leveling roller 4. Therefore, the leveling effect of the material can be improved.

[0062] Sliding grooves 451 are formed on both side walls of the through groove 45. Both sides of the moving plate 7 are located in the sliding grooves 451, and the sliding grooves 451 enable the moving plate 7 to be slidably connected in the through groove 45. The pressing roller 71 is spindle-shaped, so that the pressing roller 71 can protrude from the peripheral surface of the leveling roller 4, and no stepped surface will be formed on the surface of the leveling roller 4, and no bulge will be caused to the material during the moving process.

[0063] A support rod 72 is fixedly connected to one side of the moving plate 7 close to the axis of the leveling roller 4. One end of the support rod 72 far from the moving plate 7 is fixedly connected with an arc-shaped plate 73; a single-thread reciprocating screw rod 74 matched with the arc-shaped plate 73 is arranged through the axis of the leveling roller 4. The arc-shaped plate 73 is in threaded cooperation with the single-thread reciprocating screw rod 74. The end of the single-thread reciprocating screw rod 74 passes through the connecting shaft 41 and is fixedly connected with the support plate 51. Therefore, the single-thread reciprocating screw rod 74 does not rotate with the leveling roller 4, but the arc-shaped plate 73 can rotate with the leveling roller 4. Therefore, the arc-shaped plate 73 can be driven by the single-thread reciprocating screw rod 74 to perform reciprocating motion.

[0064] Limiting grooves 452 are formed on both side walls of the through groove 45. The arc-shaped plate 73 is located in the limiting grooves 452. The limiting grooves 452 can enable the arc-shaped plate 73 and the single-thread reciprocating screw rod 74 to be closely matched without separation, so that the single-thread reciprocating screw rod 74 can better drive the arc-shaped plate 73 to move.

[0065] There are two cooling cavities 44 in the leveling roller 4, and the two cooling cavities 44 are respectively located on both sides of the through groove 45, so that the through groove 45 will not damage the cooling cavity 44.

[0066] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
