The side of each spring 50 away from the adjusting plate is equipped with a contact rubber block 51.The right sides of multiple cold boxes 14 are in contact with the left side of the support frame 29, and the bottom right sides of multiple hot boxes 13 are in contact with the top left side of the support frame 29. The bottom of the support frame 29 is slidably connected to the top right side of the equipment base 1. An adjustment slot 2 is provided on the top left side of the equipment base 1, and the multiple cold boxes 14 are rotatably connected to the adjustment slot 2.

From top to bottom, the first adjusting plate 33, the second adjusting plate 34, the third adjusting plate 35, the fourth adjusting plate 36, and the fifth adjusting plate 37 are set on the support plate 38. The right sides of the first adjusting plate 33, the second adjusting plate 34, the third adjusting plate 35, the fourth adjusting plate 36, and the fifth adjusting plate 37 are all in contact with a pusher 4. 5. A connecting plate 44 is installed on the right side of the push frame 45. Two pneumatic telescopic rods 43 are installed on the right side of the connecting plate 44. Two pneumatic telescopic rods 39 are installed at the bottom of the support plate 38. A fixing plate 40 is provided at the bottom of the support frame 29. The bottom of the cylinders of the two pneumatic telescopic rods 39 are engaged with the top of the fixing plate 40. Two pneumatic telescopic rods 42 are installed on the right side of the fixing plate 40. An inner groove 41 is provided on the equipment base 1 at the bottom of the support frame 29. Reverse connecting rods 47 are threaded to the front and rear ends of the connecting plate 44 on the side of the pressure frame 30. Pneumatic telescopic rods 48 are installed on the top left side of the two reverse connecting rods 47 respectively. The two reverse connecting rods 47 have connecting rod movable grooves 49 adapted for sliding connection. The two connecting rod movable grooves 49 are both located on the equipment base 1 above the connecting plate 44.

[0025] Extrusion racks 15, 27, 39, 421, and 523 are driven by DC motor 7 to rotate on the adjusting movable spindle 4. These racks rotate sequentially to contact the abutment 29, where they are supported and fixed. Since plastic hollow sheets have different thicknesses during extrusion, discharge troughs 16, 28, 30, 42, and 5 represent different thicknesses, allowing for convenient and automatic switching and adjustment to accommodate different thicknesses. When extrusion rack 15 rotates to contact the abutment 29... When the sheet metal is on the frame 29, it will be extruded through the discharge trough 16. The discharge trough 16 has a thickness of one specification, and its lateral dimension is also adjustable. The pneumatic telescopic rod 39 drives the support plate 38 to raise the first adjusting plate 33, the second adjusting plate 34, the third adjusting plate 35, the fourth adjusting plate 36, and the fifth adjusting plate 37 into the adjusting groove 32. In this way, the fifth adjusting plate 37 at the bottom will be in the same straight line as the discharge trough 16. Then, the pneumatic telescopic rod 43 drives the pusher 45 on the connecting plate 44 to push the fifth adjusting plate 37 into the discharge trough 16, reducing the lateral dimension inside the discharge trough 16 for adjustment. The dimensions of the discharge troughs 2 18, 3 20, 4 22, and 5 24 are adjusted in the same way as the discharge trough 16. After a sheet of a certain size is extruded from the discharge trough 16 on the extrusion rack 15, the pneumatic telescopic rod 22 drives the abutment 29 and the first adjusting plate 33, second adjusting plate 34, third adjusting plate 35, fourth adjusting plate 36, and fifth adjusting plate 37 mounted on it to move away from the extrusion rack 15. When it is necessary to push the fifth adjusting plate 37 out of the discharge trough 16, the pneumatic telescopic rod 33 extends in the opposite direction. The pneumatic telescopic rod 33 pushes the connecting plate 44, and the connecting plate 44 drives the pusher 45 to move. The pusher 45 comes into contact with the fifth adjusting plate 37, and due to the movement of the pusher 45, an outward pushing force is generated on the fifth adjusting plate 37. Under the action of this thrust, the fifth adjusting plate 37 overcomes the friction with the inner wall of the discharge trough 16 and other possible resistances, and moves outward along the direction of the discharge trough 16, thereby realizing the action of squeezing out from the discharge trough 16. Springs 50 and contact rubber blocks 51 are installed between the fifth adjusting plate 37, the fourth adjusting plate 36, the third adjusting plate 35, the second adjusting plate 34 and the first adjusting plate 33 and the discharge trough 16.When the pneumatic telescopic rod 3 43 extends to the left to push the adjusting plate into the discharge chute, the spring 50 is compressed and accumulates elastic potential energy. When the adjusting plate needs to be pushed out, the pneumatic telescopic rod 3 43 shortens to release the thrust, and the elastic restoring force of the spring pushes the adjusting plate to slide back to the right along the discharge chute, completing the exit action. The elastic element assists in achieving the reverse movement. In addition, an auxiliary pneumatic telescopic rod 48 is added on the other side of the connecting plate 44 to form a push-pull combination with the pneumatic telescopic rod 3 43. When the adjusting plate needs to be pushed into the discharge chute 16, the pneumatic telescopic rod 3 43 extends to push the pusher 45 and the adjusting plate. When the adjusting plate is exited, the pneumatic telescopic rod 3 43 remains in the retracted state, and the auxiliary pneumatic telescopic rod 48 extends to pull the connecting plate 44 from the opposite direction, driving the pusher 45 to pull the adjusting plate out of the discharge chute 16. Through the coordinated action of the two rods, the limitation of the single rod's unidirectional extension and retraction is made up for, realizing the bidirectional movement control of the adjusting plate. Then, the DC motor 7 drives the drive gear 6. When the drive gear 6 rotates, it drives the driven gear 5 to rotate. Before rotation, the pneumatic telescopic rod 42 drives the support frame 29 and the first adjustment plate 33, second adjustment plate 34, third adjustment plate 35, fourth adjustment plate 36 and fifth adjustment plate 37 on it to approach the extrusion rack 17. The driven gear 5 drives the extrusion rack 17 on the adjustment movable main shaft 4 to rotate to the top left side of the support frame 29 and stop. The support frame 29 fixes the extrusion rack 17. Then, the sheet material is processed and extruded to another specification size through the discharge chute 18. The operation steps are the same as those for the discharge chute 16. The same operation steps are applied to the discharge chute 20, discharge chute 22 and discharge chute 24. When processing and extruding sheet material, it is possible to easily switch between extruding sheet material of different thicknesses. The width of the sheet material can also be adjusted during extrusion. It is versatile, convenient and efficient.

[0026] The right sides of multiple temperature heating boxes 13 sequentially contact the left side of the pressure frame 30. An adjustment groove 32 is provided on the top left side of the pressure frame 30. The vertical lengths of the first adjustment plate 33, the second adjustment plate 34, the third adjustment plate 35, the fourth adjustment plate 36, and the fifth adjustment plate 37 are all equal to the internal vertical length of the adjustment groove 32. The adjustment groove 32 is set on the pressure frame 30 and is used to place the first adjustment plate 33, the second adjustment plate 34, the third adjustment plate 35, the fourth adjustment plate 36, and the fifth adjustment plate 37.

[0027] The height of discharge trough 16 is equal to the height of the fifth adjusting plate 37; the height of discharge trough 2 18 is equal to the height of the fourth adjusting plate 36; the height of discharge trough 3 20 is equal to the height of the third adjusting plate 35; the height of discharge trough 4 22 is equal to the height of the second adjusting plate 34; and the height of discharge trough 5 24 is equal to the height of the first adjusting plate 33. The lateral width of the first adjusting plate 33, the second adjusting plate 34, the third adjusting plate 35, the fourth adjusting plate 36, and the fifth adjusting plate 37 is equal to the lateral width of the through trough 31. The fifth adjusting plate 37 adjusts the width of the extruded sheet material in discharge trough 16; the fourth adjusting plate 36 adjusts the width of the extruded sheet material in discharge trough 2 18; the third adjusting plate 35 adjusts the width of the extruded sheet material in discharge trough 3 20; the second adjusting plate 34 adjusts the width of the extruded sheet material in discharge trough 4 22; and the first adjusting plate 33 adjusts the width of the extruded sheet material in discharge trough 5 24.

[0028] Two pneumatic telescopic rods 39, 42, and 43 are driven synchronously. The two pneumatic telescopic rods 39 simultaneously drive the fixed plate 40 to raise and lower the first adjusting plate 33, second adjusting plate 34, third adjusting plate 35, fourth adjusting plate 36, and fifth adjusting plate 37 within the passageway 31. This causes the first adjusting plate 33 to be aligned with the corresponding discharge chute 24, and the second adjusting plate 34 to be aligned with the corresponding discharge chute 24. 22. The third adjusting plate 35 is matched with the corresponding discharge trough 20, the fourth adjusting plate 36 is matched with the corresponding discharge trough 18, and the fifth adjusting plate 37 is matched with the corresponding discharge trough 16. The connecting plate 44 and the pusher 45 are driven by the pneumatic telescopic rod 43 to adjust the transverse width of the extruded sheet by the matched first adjusting plate 33, second adjusting plate 34, third adjusting plate 35, fourth adjusting plate 36 and fifth adjusting plate 37.

[0029] In this invention, extrusion racks 15, 17, 19, 21, and 23 are driven by a DC motor 7 to rotate on the adjusting movable spindle 4. These racks are rotated sequentially to contact the abutment frame 29, and the abutment frame 29 supports and fixes the sequentially rotating extrusion racks. Extrusion racks 15, 17, 19, 21, and 23 are for extrusion blanks. Plastic hollow sheets are processed with extruded materials of varying thicknesses. Discharge troughs 16, 18, 20, 22, and 24 represent specifications for different thicknesses. Plastic hollow sheets are made from discharge troughs of varying thicknesses. The material trough 24 is used for extrusion. When the extrusion rack 15 rotates on the support frame 29, the sheet material is extruded through the discharge trough 16. The discharge trough 16 has a thickness of one specification, and its lateral dimension is also adjustable. The pneumatic telescopic rod 39 drives the support plate 38 to raise the first adjustment plate 33, the second adjustment plate 34, the third adjustment plate 35, the fourth adjustment plate 36, and the fifth adjustment plate 37 into the adjustment trough 32. In this way, the fifth adjustment plate 37 at the bottom will be in the same straight line as the discharge trough 16. Then, the pneumatic telescopic rod 43 drives the pusher 45 on the connecting plate 44 to push the fifth adjustment plate 37 into the discharge trough 16, reducing the lateral dimension inside the discharge trough 16 for adjustment. The dimensions of the discharge troughs 28, 320, 42, and 524 are adjusted in the same way as the discharge trough 16. After a sheet of a certain size is extruded from the discharge trough 16 on the extrusion rack 15, the pneumatic telescopic rod 22 drives the abutment 29 and the first adjusting plate 33, second adjusting plate 34, third adjusting plate 35, fourth adjusting plate 36, and fifth adjusting plate 37 mounted on it to move away from the extrusion rack 15. When it is necessary to push the fifth adjusting plate 37 out of the discharge trough 16, the pneumatic telescopic rod 33 extends in the opposite direction. The pneumatic telescopic rod 33 pushes the connecting plate 44, and the connecting plate 44 drives the pusher 45 to move. The pusher 45 comes into contact with the fifth adjusting plate 37, and due to the movement of the pusher 45, an outward pushing force is generated on the fifth adjusting plate 37.Under this thrust, the fifth adjusting plate 37 overcomes the friction with the inner wall of the discharge trough 16 and other possible resistances, moving outward along the direction of the discharge trough 16, thereby realizing the extrusion action from the discharge trough 16. Then, the DC motor 7 drives the drive gear 6 to rotate, which in turn drives the driven gear 5 to rotate. Before rotation, the pneumatic telescopic rod 42 drives the support frame 29 and the first adjusting plate 33, second adjusting plate 34, third adjusting plate 35, fourth adjusting plate 36 and fifth adjusting plate 37 on it to approach the extrusion frame 17. 5 drives the extrusion rack 2 17 on the main shaft 4 to rotate and stop at the top left side of the support frame 29. The support frame 29 fixes the extrusion rack 2 17. Then, the sheet material is processed and extruded to another specification size through the discharge chute 2 18. The operation steps are the same as those for the discharge chute 1 16. The same operation steps are applied to the discharge chute 3 20, discharge chute 4 22, and discharge chute 5 24. When processing and extruding sheet material, it is possible to easily switch between extruding sheet material of different thicknesses. The width of the sheet material can also be adjusted during extrusion. It is versatile, convenient and efficient.
