Description

Technical Field

[0001] The invention relates to the technical field of pressure pipe production, in particular to a pressure pipe with internal textures and extrusion molding equipment. Background Art

[0002] A pipe extruder is a device used to produce various pipe materials. It primarily consists of an extrusion system, a transmission system, a heating and cooling system, and a control system. During operation, a polymer material, such as plastic, is fed into a hopper and pushed into a heating zone by a rotating screw. The material melts under the heat and is extruded through the die head, forming a tubular billet. This billet is then cooled, shaped, pulled, and cut to form pipes of varying specifications and applications. With its high production efficiency, stable product quality, and ease of operation, the pipe extruder is a key piece of equipment for the efficient and high-quality production of plastic pipes.

[0003] For example, the Chinese patent with authorization announcement number CN213412856U discloses a new traction wheel mechanism of a traction machine, including a hot air input mechanism and an exhaust cooling mechanism. The two power output shafts and the two traction wheels of the electric traction wheel device body are hollow structures. One side of the two power output shafts is respectively installed in the middle of one end of the traction wheel and communicates with the inside of the traction wheel, and the other side of the two power output shafts is located at the outer end of the shell of the electric traction device body; the hot air input mechanism has two identical sets, each set of hot air input mechanism includes a sleeve, a bearing, and a connecting pipe. There are at least two bearings, which are tightly fitted on the left and right sides of the sleeve. One end of the connecting pipe is tightly fitted in the inner ring of the right end bearing in the sleeve; the inner rings of the bearings at the left ends of the sleeves of the two sets of hot air input mechanisms are respectively tightly fitted on the other side outer ends of the two power output shafts; the hot air blower is installed at the lower end of the extruder frame, and the hot air blower exhaust pipe and the other side ends of the connecting pipes of the two sets of hot air input mechanisms are respectively connected by pipes; the exhaust cooling mechanism is installed at the upper end of the shell of the electric traction device body.

[0004] However, there are still some problems with the existing traction mechanism. When the traction work is first performed, the traction tube needs to be passed through the traction device, and then the newly extruded pipe needs to be put on the traction tube and abutted against the traction tube, and then the traction tube is pulled to complete the extrusion and traction work of the pipe. However, there are still some problems with the above traction work. In order to ensure that the new pipe material, that is, the newly extruded part, can adhere to the traction tube, the traction tube needs to be heated. The existing traction tube heating is mostly through a ring-shaped resistance wire, and then the traction tube is heated by energizing the resistance wire. However, this method is difficult to control the temperature of the traction tube, which will cause the temperature of the traction tube to be too high or too low. When it is too high, it will cause the traction tube to deform, and when it is too low, it will cause the new pipe material to be difficult to adhere to the traction tube, making it difficult to pull the pipe.

[0005] Therefore, how to complete the traction work of the pipeline is a problem that needs to be solved at present. Summary of the Invention

Detailed implementation manners

[0045] In order to make the above - mentioned objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be made with reference to the accompanying drawings of the specification.

[0046] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0047] Secondly, the so - called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0048] The present invention discloses an extrusion - forming device. Refer to Figures 1 - 8 , including:

[0049] Extruder 1, which is used for melting and extruding plastic particles to complete the production of pressure pipes; a shaping box 5, which is used for transporting the pressure pipes extruded by the extruder 1 and is internally provided with a traction pipe to shape the pressure pipes during transportation; a cutting unit 3, which is located between the extruder 1 and the shaping box 5 and is used for cutting the new material extruded from the extruder 1; a docking unit 4, which is used for transporting the cut new material and sleeving the annular new material on the traction pipe to increase the temperature of the traction pipe; the docking unit 4 includes an adjustment assembly 41, a pressing assembly 42, a first fixing plate 43 and a second fixing plate 44; the first fixing plate 43 is connected to the extruder 1; the adjustment assembly 41, with three in number and arranged obliquely, is used for changing the position of the new material; the second fixing plate 44 is used for connecting the adjustment assembly 41; the pressing assembly 42 is connected to the second fixing plate 44 and is used for pressing the new material located on the traction pipe and, after completing the heating work of the traction pipe, separating the new material from the traction pipe; when the extruder 1 is performing extrusion work, the plasticity of the just-extruded pipe is small, so the just-extruded new material cannot be used for pipe production work. In this device, the cutting unit 3 can cut the new material to form an annular structure. Through the annular array suction cups 418 in the docking unit 4 and an externally connected air pump, the annular new material can be adsorbed and transported, so that the annular new material is located on the traction pipe. Then, through the pressing assembly 42 in the docking unit 4, the new material can be pressed to make the new material abut against the outer wall of the traction pipe. Since the new material is just extruded from the extruder 1, it has a certain temperature, and the traction pipe is heated by the new material. Then, through the movement of the telescopic cylinder 421, the pressing roller 4213 abuts against the surface of the traction pipe and radially abuts against the new material. Then the telescopic cylinder 421 works in the reverse direction, so that the new material is separated from the traction pipe. Then the above process is repeated to complete the heating of the traction pipe. During this working process, the temperature of the traction pipe will not exceed the temperature of the new material, so the traction pipe will not deform. At the same time, the temperature of the traction pipe can be increased by repeating the docking process, so that the subsequent extruded pipes can adhere to the traction pipe, ensuring the smooth progress of the pipe traction and extrusion work.

[0050] The adjusting assembly 41 includes a support slide rail 411 arranged obliquely, a driving motor 412 arranged on the support slide rail 411, a driving lead screw 413 connected to the output end of the driving motor 412, an adjusting block 414 connected to the driving lead screw 413, a rotating shaft 415 symmetrically arranged on the adjusting block 414, a fish-eye bearing connecting rod 416 movably connected to the rotating shaft 415, an adjusting plate 417 movably connected to the other end of the fish-eye bearing connecting rod 416, and an annular array of suction cups 418 arranged on the adjusting plate 417; through holes are provided on the first fixing plate 43, the second fixing plate 44 and the adjusting plate 417; in order to carry the new material, after the cutting unit 3 completes the cutting work on the new pipeline material, at this time the driving motor 412 starts to work, the moving driving motor 412 can drive the driving lead screw 413 to rotate, then the moving driving lead screw 413 can drive the adjusting block 414 to move, then the moving adjusting block 414 can drive the rotating shaft 415 to move, so that the moving rotating shaft 415 can drive the fish-eye bearing connecting rod 416 to move, drive the adjusting plate 417 to move, change the adjusting position, so that the annular array of suction cups 418 can adsorb the outer wall of the new pipeline material, and then complete the cutting work on the new pipeline material through the provided cutting unit 3, and then adjust the position of the new pipeline material through the cooperative work of the three support slide rails 411, so that the new pipeline material can be sleeved on the traction pipe, and then complete the warming work on the traction pipe; through the provided annular array of suction cups 418, large deformation of the annular new material is avoided, and it is avoided that the new material is difficult to be sleeved on the traction pipe, ensuring the smooth progress of the warming work on the traction pipe; and because the three driving motors 412 are independent of each other, the new pipeline material adsorbed by the annular array of suction cups 418 can be adjusted at multiple angles, so that it can be sleeved on the traction pipe, realizing the smooth progress of the docking work between the new pipeline material and the traction pipe, and then completing the warming work on the traction pipe.

[0051] The extrusion assembly 42 includes a telescopic cylinder 421 fixedly mounted on the first fixed plate 43, a rotating part 423 connected to the output end of the telescopic cylinder 421, a housing 422 connected to the rotating end of the rotating part 423, a driving part and a limit seat 4210 built in the housing 422, a bilateral rack 4211 movably connected to the limit seat 4210, a movable seat 4212 connected to the bilateral rack 4211, and an extrusion roller 4213 arranged on the movable seat 4212; the axial direction of the extrusion roller 4213 is horizontal with respect to the axial direction of the traction tube; the driving part includes a mounting shaft 424 built in the housing 422, a hinge seat 425 arranged at the top of the housing 422, a driving cylinder 426 movably connected to the hinge seat 425, a first gear 427 movably connected to the output end of the driving cylinder 426 and connected to the housing 422, rotating shafts 428 symmetrically arranged on the housing 422 and located on both sides of the limit seat 4210, two second gears 429 sleeved on the rotating shafts 428, and a toothed ring 4214 sleeved on the mounting shaft 424; one of the second gears 429 meshes with the bilateral rack 4211, and the other second gear 429 meshes with the toothed ring 4214;

[0052] In order to warm up the new pipeline material on the pulling pipe, after the new pipeline material is sleeved on the pulling pipe, the telescopic cylinder 421 starts to work at this time. The moving telescopic cylinder 421 pushes the rotating part 423 to move. The moving rotating part 423 can drive the housing 422 to move, so that the extrusion roller 4213 moves in the axial direction of the pulling pipe. After it moves a certain distance, the telescopic cylinder 421 stops working at this time, and then the driving cylinder 426 starts to work. The moving driving cylinder 426 drives the first gear 427 to rotate. Then the moving first gear 427 drives the second gear 429 engaged with it to rotate. Then the moving second gear 429 can drive another second gear 429 to rotate through the set rotating shaft 428, driving the double-sided gear to move in the length direction of the limit seat 4210, and then adjusting the position of the movable seat 4212, so that the extrusion roller 4213 abuts against the outer wall of the new pipeline material. The remaining extrusion rollers 4213 are synchronously driven through the gear ring 4214. Then the rotating part 423 drives the extrusion roller 4213 to rotate, and the new pipeline material is extruded to fit the pulling pipe, completing the warming of the pulling pipe. This avoids the situation that the pipeline cannot adhere to the pulling pipe due to the excessive temperature difference between the newly injection-molded pipeline and the pulling pipe. At the same time, warming can also improve the flexibility of the material and reduce the risk of rupture or damage during the pulling process due to stress; after the warming work is completed, the driving cylinder 426 and the telescopic cylinder 421 start to move at this time, so that the extrusion roller 4213 moves away from the new pipeline material and at the same time changes the extrusion area of the extrusion roller 4213. When the extrusion roller 4213 moves to the predetermined position, the driving cylinder 426 starts to work at this time, so that the extrusion roller 4213 abuts against the outer wall of the pulling pipe. Then the telescopic cylinder 421 starts to work again, so that the top of the extrusion roller 4213 abuts against the radial surface of the new pipeline material, causing the new pipeline material to separate from the pulling pipe. Then, by repeating the above steps, the temperature of the pulling pipe is increased to carry out the warming work on the pulling pipe.

The moving adjusting motor 32 can drive the transmission shaft 35 to rotate through the provided first bevel gear 216 and second bevel gear 217, and then can drive the transmission gear 36 on the transmission shaft 35 to rotate. Then, the remaining transmission gears 36 are all driven to rotate through the provided chain. Then, the driving gear 37 is driven to rotate through the provided transmission shaft 35, so that relative rotation occurs between the toothed ring 38 and the mounting seat 31. Since the mounting plate 39 is disposed on the toothed ring 38, the moving toothed ring 38 can drive the mounting plate 39 to rotate, and the moving mounting plate 39 can drive the cutting knife 311 to rotate, completing the cutting work on the new pipeline materials; the cutting of the pipeline can be completed through the provided cutting unit 3. At the same time, through the provided adjusting cylinder 310, the cutting work on pipelines with different thicknesses can be completed. Through the work of the provided toothed ring 38, the cutting knife 311 is rotated to complete the cutting work.

[0054] In a further embodiment, during the process of the screw rotating to push the plastic material forward, the plastic will go through stages such as plasticization and melting. The exhaust port provided in the middle of the barrel can allow the gases and volatiles in the plastic to be discharged through the exhaust channel at a specific stage, avoiding defects such as pores and bubbles in the product caused by these gases during the extrusion process, thereby improving the quality and performance of the product.

[0061] Working principle description: When it is necessary to cut new pipe material or pipe, the adjusting motor 32 starts to work. The moving adjusting motor 32 can drive the transmission shaft 35 to rotate through the first bevel gear 216 and the second bevel gear 217, and then drive the transmission gear 36 on the transmission shaft 35 to rotate. Then, the remaining transmission gears 36 are all rotated through the provided chain. Then, the driving gear 37 is driven to rotate through the provided transmission shaft 35, so that the gear ring 38 and the mounting seat 31 rotate relative to each other. Since the mounting plate 39 is provided on the gear ring 38, the moving gear ring 38 can drive the mounting plate 39 to rotate, and the moving mounting plate 39 can drive the cutting knife 311 to rotate.

[0062] In order to transport the new material, after the cutting unit 3 completes the cutting work of the new pipe material, the driving motor 412 starts to work, and the moving driving motor 412 can drive the driving screw 413 to rotate, and then the moving driving screw 413 can drive the adjusting block 414 to move, and then the moving adjusting block 414 can drive the rotating shaft 415 to move, so that the moving rotating shaft 415 can drive the fisheye bearing connecting rod 416 to move, and drive the adjusting plate 417 to move, change the adjustment position, so that the annular array suction cup 418 can adsorb the outer wall of the new pipe material, and then the cutting work of the new pipe material is completed by the set cutting unit 3, and then the position of the new pipe material is adjusted by the cooperation of the set three supporting slide rails 411, so that the new pipe material can be sleeved on the traction tube, thereby completing the warming work of the traction tube;

[0063] After the new pipeline material is sleeved on the traction pipe, the telescopic cylinder 421 starts to work at this time. The moving telescopic cylinder 421 pushes the rotating part 423 to move. The moving rotating part 423 can drive the housing 422 to move, so that the extrusion roller 4213 moves in the axial direction of the traction pipe. After it moves a certain distance, the telescopic cylinder 421 stops working at this time, and then the driving cylinder 426 starts to work. The moving driving cylinder 426 drives the first gear 427 to rotate. Furthermore, the moving first gear 427 drives the second gear 429 meshing with it to rotate. Then the moving second gear 429 can drive another second gear 429 to rotate through the set rotating shaft 428, driving the bilateral gear to move in the length direction of the limit seat 4210, and then adjusting the position of the movable seat 4212, so that the extrusion roller 4213 abuts against the outer wall of the new pipeline material. The remaining extrusion rollers 4213 are synchronously driven through the gear ring 4214. Then the rotating part 423 drives the extrusion roller 4213 to rotate, and the new pipeline material is extruded to fit the traction pipe, completing the warming of the traction pipe; after the warming work is completed, the driving cylinder 426 and the telescopic cylinder 421 start to move at this time, so that the extrusion roller 4213 moves away from the new pipeline material and at the same time changes the extrusion area of the extrusion roller 4213. When the extrusion roller 4213 moves to the set position, the driving cylinder 426 starts to work at this time, so that the extrusion roller 4213 abuts against the outer wall of the traction pipe. Then the telescopic cylinder 421 starts to work again, so that the top of the extrusion roller 4213 abuts against the radial surface of the new pipeline material, so that the new pipeline material is separated from the traction pipe. Then by repeating the above steps, the temperature of the traction pipe is increased to carry out the warming work on the traction pipe;

[0064] When the first actuator and the second actuator need to work, the actuating motor 21 starts to work at this time. The moving actuating motor 21 can drive the rotating seat 23 to rotate, thereby driving the movable shaft 24 to move. The rotating movable shaft 24 can drive the third gear 26 to move, so that the moving third gear 26 can drive the fourth gear 27 to rotate. The moving fourth gear 27 can drive the coupling shaft 28 to rotate. At this time, the moving coupling shaft 28 can drive the first actuator and the second actuator to move, thereby driving the hammering rod 212 to perform a predetermined movement, completing the cleaning or opening of the solidified plastic, and ensuring the smooth discharge of the gas in the extruder 1. When the coupling shaft 28 starts to rotate, the moving coupling shaft 28 can drive the cam 29 to move, and then the moving cam 29 can drive the actuating rod 210 to move, so that the driven rod 211 and the hammering rod 212 can move in their axial directions, enabling the hammering rod 212 to impact the solidified plastic. After the coupling shaft 28 starts to rotate, the moving coupling shaft 28 can drive the main gear 213 to move, and then the moving main gear 213 can drive the driven gear 214 to rotate. The third bevel gear 33 is driven to move through the provided connecting shaft 215, and then the moving third bevel gear 33 drives the fourth bevel gear 34 to move, thereby driving the rotating rod 218 to rotate and driving the fifth gear 219 to rotate. Then the moving fifth gear 219 can drive the sixth gear 25 to rotate, and the moving sixth gear 25 drives the hammering rod 212 to rotate, enabling the hammering rod 212 to open a hole in the solidified plastic and ensuring the smooth progress of the gas discharge work.
