[0002] Plastic raw materials are added into an extruder through a hopper. After the screw is preheated, the plastic raw materials enter the barrel under the action of gravity or a feeding screw. Under the thrust and shearing action of the screw, the plastic gradually softens and melts, forming a continuous and uniform material flow. The completely plasticized and melted plastic is pushed into the head. Through the head and the die, the molten plastic is extruded into the required pipe.

[0003] The extruded pipe is discharged outwards through the die outlet. During the discharging process, a conveyor is used to convey the pipe, and then a cutter is used to complete the cutting of the pipe. Most conveyors of common pipe sizing devices are belt structures. The belt structure includes two positioning frames and two conveyor belts. One positioning frame is arranged above the die outlet, and the other positioning frame is arranged below the die outlet. The pipe passes through the middle, and the conveyor belts of the positioning frames send the pipe outwards.

Specific implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0024] According to Figure 1 、 2 As shown in 3, 4, 5, a pipe shaping device is proposed in this embodiment, which includes an extruder 1, a cooling box 4, a pipe conveyor 5 and a slitter 6. The cooling box 4 is placed between the extruder 1 and the pipe conveyor 5, and the pipe conveyor 5 is placed between the slitter 6 and the cooling box 4. A hopper 2 and a discharge port 3 are provided on the extruder 1, and the discharge port 3 is communicated with the cooling box 4;

[0025] Plastic raw materials are added into the extruder 1 through the hopper 2. After being heated, the plastic gradually softens and melts under the thrust and shearing action of the screw in the extruder 1, forming a continuous and uniform material flow. The completely plasticized and melted plastic is pushed into the discharge port 3. It enters the cooling box 4 through the discharge port 3, and the molten plastic is extruded into the required tubular shape and cooled.

[0026] The pipeline conveyor 5 includes a machine platform 7. At the upper end of the machine platform 7, there are two fixed piles 8. Between the two fixed piles 8, there are two movable brackets 9. The two movable brackets 9 are arranged vertically and are slidably connected to the fixed piles 8. On the side where the two movable brackets 9 are close to each other, there is a conveyor belt 10.

[0027] The cooled and shaped pipeline is discharged from the outlet of the cooling box 4 and passes between the two movable brackets 9. The conveyor belt 10 on the movable brackets 9 sends the pipeline outwards, and the cutting machine 6 cuts the pipeline.

[0028] On the fixed pile 8, there is a lifting mechanism for adjusting the height of the movable bracket 9. At both ends of the movable bracket 9, there is a positioning wheel structure for restricting the offset of the pipeline. The positioning wheel structure is detachably connected to the movable bracket 9.

[0029] The lifting mechanism is used to adjust the height between the two movable brackets 9 to ensure that the conveyor belt 10 on the movable brackets 9 is in close contact with the pipeline. In addition to playing a role in conveying the pipeline, the positioning wheel structure arranged at both ends of the movable bracket 9 will limit the pipeline, so that the pipeline will not shift during transportation, improving the cutting quality.

[0030] Regarding the positioning wheel structure:

[0031] The positioning wheel structure includes four fixed columns 12 fixedly connected to both ends of the movable bracket 9. On the side of the fixed column 12 facing the pipeline, there is a limit wheel seat 14. On the limit wheel seat 14, there is a limit wheel 13. The limit wheel 13 is rotatably connected to the limit wheel seat 14. At the upper end of the limit wheel seat 14, there is a positioning column 15. The positioning column 15 is fixedly connected to the limit wheel seat 14, and the positioning column 15 is detachably connected to the fixed column 12.

[0032] The cooled and shaped pipeline is discharged from the outlet of the cooling box 4. The fixed columns 12 are fixed at the left and right ends of the movable bracket 9. The pipeline passing between the two movable brackets 9 will pass between the respective limit wheel seats 14. Each limit wheel 13 surrounds the pipeline. While not restricting the forward delivery of the pipeline, by guiding the pipeline, it avoids the pipeline from shifting during discharging.

[0033] Specifically, the fixed column 12 is provided with a slot allowing the positioning column 15 to penetrate into it. The slot is slidably connected to the positioning column 15. On the outside of the fixed column 12, there is a bolt connecting piece for fixing the fixed column 12 and the positioning column 15. The limit wheel seat 14 is fixed to the fixed column 12 in a plug-and-play manner. When removing the limit wheel seat 14 from the fixed column 12 for replacement, the fixing of the positioning column 15 by the bolt connecting piece can be released.

[0034] It is further worth noting that the bolt connection member includes a fixing bolt 17, which is threadedly connected to one end of the fixing column 12 away from the movable bracket 9. The fixing bolt 17 penetrates into the slot. A plurality of positioning holes 16 that are threadedly engaged with the fixing bolt 17 are formed on the outer side of the positioning column 15, and the positioning holes 16 are evenly arranged along the length direction of the positioning column 15. Rotate the fixing bolt 17 to screw the fixing bolt 17 out of the positioning hole 16, and the positioning column 15 can slide normally along the slot to adjust the fixed position of the positioning column 15, so that the limiting wheel 13 remains in close contact with the outer wall of the pipeline.

[0035] Regarding the lifting mechanism:

[0036] The lifting mechanism includes a chute 18, which is formed on one side of the fixing pile 8 close to the movable bracket 9. A double-headed screw 19 and two mating blocks 20 are arranged in the chute 18. The mating blocks 20 are slidably connected to the chute 18, the double-headed screw 19 is rotatably connected to the chute 18, the mating blocks 20 are sleeved on the outer side of the double-headed screw 19, and the double-headed screw 19 is threadedly connected to the mating blocks 20. An electric motor 11 is provided at the upper end of the fixing pile 8, and the output end of the electric motor 11 is fixedly connected to the double-headed screw 19. The mating blocks 20 are fixedly connected to the movable bracket 9. The electric motor 11 drives the double-headed screw 19 to rotate. During the rotation of the double-headed screw 19, it cooperates with the mating blocks 20 and moves along the rod body of the double-headed screw 19. Since the mating blocks 20 are fixed to the movable bracket 9, when the mating blocks 20 move, the movable bracket 9 will also drive the conveyor belt 10 to move together, so that the conveyor belt 10 is in close contact with the pipeline.

[0037] It is further worth noting that the two mating blocks 20 are respectively sleeved on both ends of the double-headed screw 19, and two sets of positive and negative threads are formed on the outer side of the double-headed screw 19, and the two sets of threads are respectively threadedly connected to the two mating blocks 20. Since the thread directions on the outer side of the double-headed screw 19 are opposite, when the double-headed screw 19 rotates, the two mating blocks 20 sleeved on the outer side of the double-headed screw 19 will move in opposite directions along the rod body of the double-headed screw 19.

[0038] To facilitate the transfer of the pipeline shaping device by the operator, pulley seats are provided at the bottoms of the extruder 1, the machine platform 7, the pipeline conveyor 5, and the slitter 6. The pulley seats are fixedly connected to the corners at the bottom of the machine platform 7, and pulleys are provided on the pulley seats. The pulleys at the bottoms of the extruder 1, the machine platform 7, the pipeline conveyor 5, and the slitter 6 support the extruder 1, the machine platform 7, the pipeline conveyor 5, and the slitter 6 to move on a smooth ground to adjust the setting position of the device.

[0039] The working principle of this application:

[0040] The plastic raw material is added into the extruder 1 through the hopper 2. After being heated, the plastic gradually softens and melts under the thrust and shearing action of the screw in the extruder 1, forming a continuous and uniform material flow. The completely plasticized and melted plastic is pushed into the discharge port 3. It enters the cooling box 4 through the discharge port 3, and the molten plastic is extruded into the required tubular shape and cooled. The cooled and shaped pipe is discharged from the outlet of the cooling box 4 and passes between two movable brackets 9. The conveyor belt 10 on the movable brackets 9 sends the pipe outwards, and the cutting machine 6 cuts the pipe. The lifting mechanism is used to adjust the height between the two movable brackets 9 to ensure that the conveyor belt 10 on the movable brackets 9 is in close contact with the pipe. In addition to playing a role in conveying the pipe, the positioning wheel structure arranged at both ends of the movable bracket 9 limits the pipe, so that the pipe will not shift during transportation, improving the cutting quality.
