[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please see Figure 1-5 An annealing device for processing plastic sheets and rods includes a workbench 1, a box 2 fixedly connected to one side of the top of the workbench 1, a fixed plate 3 fixedly connected to one side of the inside of the box 2, a first turntable 4 rotatably connected to the inner side of the fixed plate 3 at equal intervals, a limit plate 5 slidably connected to the inner side of the workbench 1 away from the fixed plate 3, a second turntable 6 rotatably connected to the inner side of the limit plate 5 at equal intervals, a hot air frame 7 slidably connected to the upper part of the inside of the box 2 through a limit rod, a cooling sloping groove 8 opened on the top of the workbench 1, and a transmission assembly installed inside the box 2.
[0022] Specifically, the transmission assembly includes a reciprocating screw 9 and a linkage unit. The reciprocating screw 9 is rotatably connected to the upper interior of the housing 2. The hot air frame 7 is threadedly connected to the exterior of the reciprocating screw 9. A motor 10 is fixedly connected to the exterior of the housing 2 via a mounting plate. The output end of the motor 10 extends into the interior of the housing 2 and is fixedly connected to the reciprocating screw 9. A cylinder 16 is fixedly connected to the exterior of the housing 2 away from the motor 10 via a mounting bracket. The output end of the cylinder 16 extends into the interior of the housing 2 and is fixedly connected to the limiting plate 5. The first turntable 4 can be rotated via the linkage unit, which includes a first synchronous pulley 11. Stepping wheel 11 is fixedly connected to the outside of the output end of motor 10. A first gear 12 is rotatably connected to the outside of fixed plate 3. The outside of the first gear 12 extends to the outside of housing 2 via a rotating shaft and is fixedly connected to a second synchronous pulley 13. The first synchronous pulley 11 and the second synchronous pulley 13 are connected by a synchronous belt 14. A second gear 15 is rotatably connected to the outside of fixed plate 3 on both sides of the first gear 12. The two second gears 15 mesh with the first gear 12. The first gear 12 and the two second gears 15 extend to the inside of fixed plate 3 via rotating shafts and are fixedly connected to the corresponding first turntable 4.
[0023] With the above technical solution, after the plastic sheet and plastic rod are produced, the first box door 20 is opened on the production line, and the plastic sheet or rod to be annealed is placed between the first turntable 4 and the second turntable 6, and inserted into the round or square groove on the inner side of the first turntable 4. Then, the cylinder 16 is started, and the output end of the cylinder 16 pushes the limiting plate 5 to move inward until it drives the second turntable 6 to clamp the plastic sheet or rod with the first turntable 4 through the round or square groove on its inner side. Then, the motor 10 and the hot air blower 17 are started, and the output end of the motor 10 drives the reciprocating screw 9. The rotation of the first synchronous pulley 11 causes the reciprocating screw 9 to drive the hot air frame 7 to reciprocate under the limit of the limit rod through the threaded connection. This drives the hot air frame 7 and the nozzle 19 to evenly blow the hot air generated by the hot air blower 17 onto the surface of the plastic plate, ensuring uniform heating of the plastic plate. During the rotation of the first synchronous pulley 11, the synchronous belt 14 drives the second synchronous pulley 13 and the first gear 12 to rotate. The first gear 12 then drives the two second gears 15 to rotate through the meshing relationship, so that the first gear 12 and the two second gears 15... The first turntable 4 rotates, which in turn drives the second turntable 6 to rotate the plastic plate at a uniform speed, further ensuring the uniformity of heating the plastic plate and effectively improving the annealing effect and efficiency. After the plastic plate is heated, the second box door 21 is opened, and the cylinder 16 is controlled to move the limit plate 5 back to its original position, allowing the plastic plate to fall naturally into the cooling trough 8 at the top of the workbench 1. The cooling water pre-injected into the cooling trough 8 cools the plastic plate, and after cooling, it can be directly removed and collected. This device effectively improves ease of use. It can clamp the plastic plate rod by moving the first turntable 4 and the second turntable 6 in conjunction with the limiting plate 5, and drive the plastic plate rod to rotate during the heating process. The reciprocating hot air frame 7 blows hot air evenly onto the surface of the plastic plate rod, ensuring the uniformity of heating. This effectively improves the annealing effect and efficiency of the plastic plate rod. After heating, the plastic plate rod can be easily dropped into the cooling trough 8 for cooling, facilitating collection after processing.
[0024] Specifically, a hot air blower 17 is fixedly connected to the top of the housing 2, and a flexible hose 18 is fixedly connected to the outside of the hot air blower 17. One end of the flexible hose 18 extends into the inside of the housing 2 and is fixedly connected to the hot air frame 7. Spray nozzles 19 are fixedly connected at equal intervals to the bottom of the hot air frame 7. A first door 20 is installed on the outside of the housing 2 and above the cylinder 16. A second door 21 is installed at the bottom of the housing 2. Square grooves and round grooves are opened on the inner sides of the multiple first turntables 4 and second turntables 6. The flexible hose 18 and the spray nozzles 19 are connected through an internal channel.
[0025] The above technical solution allows for better clamping and fixing of the plastic rod and plastic plate using the square and round grooves, thus improving stability during the heating process.
[0026] In use, after the plastic sheets and rods are produced, the first box door 20 is opened on the production line. The plastic sheets and rods that need to be annealed are placed between the first turntable 4 and the second turntable 6, and inserted into the round or square groove on the inner side of the first turntable 4. Then, the cylinder 16 is started, and the output end of the cylinder 16 pushes the limiting plate 5 to move inward until it drives the second turntable 6 to clamp the plastic sheets and rods through its inner round or square groove with the first turntable 4. Then, the motor 10 and the hot air blower 17 are started. The output end of the motor 10 drives the reciprocating screw 9 and the first synchronous pulley 11 to rotate, so that the reciprocating screw 9 rotates and the first synchronous pulley 11 rotates. The lead screw 9, through a threaded connection, drives the hot air frame 7 to reciprocate under the limit of the limiting rod. This allows the hot air frame 7 and the nozzle 19 to evenly blow the hot air generated by the hot air blower 17 onto the surface of the plastic plate, ensuring uniform heating of the plastic plate. Furthermore, during the rotation of the first synchronous pulley 11, the synchronous belt 14 drives the second synchronous pulley 13 and the first gear 12 to rotate. The first gear 12, in turn, meshes with two second gears 15, causing the first gear 12 and the two second gears 15 to drive the corresponding first turntable 4 to rotate, thus cooperating with the second turntable 6 to... The plastic plate rotates at a uniform speed, further ensuring the uniformity of heating and effectively improving the annealing effect and efficiency. After the plastic plate is heated, the second door 21 is opened, and the cylinder 16 is controlled to move the limit plate 5 back to its original position, allowing the plastic plate to fall naturally into the cooling trough 8 at the top of the workbench 1. The plastic plate is cooled by the cooling water pre-injected into the cooling trough 8, and can be directly removed and collected after cooling, effectively improving the ease of use of this device. This device can be connected to the first turntable 4 and the second turntable. 6. The movement of the limiting plate 5 clamps the plastic plate and rod, causing it to rotate during heating. The reciprocating hot air frame 7 evenly blows hot air onto the surface of the plastic plate and rod, ensuring uniform heating and effectively improving the annealing effect and efficiency. After heating, the plastic plate and rod can be easily dropped into the cooling chute 8 for cooling, facilitating collection after processing. The square and round grooves provide better clamping and fixing of the plastic rod and plate, improving stability during heating.
