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] Pipe extruder is a kind of equipment used to produce various pipes. It is mainly composed of extrusion system, transmission system, heating and cooling system, control system and other parts. When working, plastic and other polymer materials are added to the hopper and pushed to the heating zone by the rotation of the screw. The material is melted by heat and extruded from the die head to form a tubular blank. After cooling, shaping, pulling, cutting and other processes, it is made into pipes of different specifications and uses. Pipe extruder has the advantages of high production efficiency, stable product quality and simple operation. It is a key equipment to achieve efficient and high-quality production of plastic pipes.

[0003] For example, a Chinese patent with the authorization announcement number CN213412856U discloses a new type of traction wheel mechanism for a traction machine, including a hot air input mechanism and an exhaust cooling mechanism. The two power output shafts and 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 side 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 the hot air input mechanism includes a sleeve, a bearing, and a connecting pipe. There are at least two bearings, which are tightly sleeved on the left and right sides of the inside of the sleeve, and one side end of the connecting pipe is tightly sleeved 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 sleeved on the other side outer ends of the two power output shafts; the hot air blower is installed at the lower end of the frame of the extruder, 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 through pipelines; 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 performed at the beginning, 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, it is necessary to heat the traction tube. The existing traction tube heating is mostly through an annular 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 traction tube temperature 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

[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

The first fixing plate 43 is connected to the extruder 1; the adjusting components 41 are three in number and are arranged obliquely to change the position of the new material; the second fixing plate 44 is used to connect the adjusting components 41; the extrusion component 42 is connected to the second fixing plate 44 to extrude the new material on the traction tube and separate the new material from the traction tube after the traction tube is heated; when the extruder 1 is extruding, the plasticity of the newly extruded pipe is small, so the newly extruded new material cannot be used for pipe making. In this device, The cutting unit 3 is provided to cut the new material so that it can form an annular structure, and the annular array suction cup 418 in the docking unit 4 can be connected to an external air pump to absorb and transport the annular new material, so that the annular new material is located on the traction tube, and then the extrusion assembly 42 in the docking unit 4 can be used to extrude the new material so that the new material abuts against the outer wall of the traction tube. Since the new material has just been extruded from the extruder 1, it has a certain temperature. The traction tube is warmed by the new material, and then the extrusion roller 4213 abuts against the surface of the traction tube and radially abuts against the new material through the movement of the telescopic cylinder 421. Then the telescopic cylinder 421 works in the reverse direction to separate the new material from the traction tube, and then the above process is repeated to complete the warming of the traction tube. During this working process, the temperature of the traction tube will not exceed the temperature of the new material, so the traction tube will not be deformed. At the same time, the temperature of the traction tube can be increased by repeating the docking process, so that the subsequent extrusion pipeline can be attached to the traction tube, ensuring the smooth progress of the pipeline traction extrusion work.

[0024] The adjustment component 41 includes an inclined support rail 411, a driving motor 412 arranged on the supporting rail 411, a driving screw 413 connected to the output end of the driving motor 412, an adjustment block 414 connected to the driving screw 413, a rotating shaft 415 symmetrically arranged on the adjustment block 414, a fisheye bearing connecting rod 416 movably connected to the rotating shaft 415, an adjustment plate 417 movably connected to the other end of the fisheye bearing connecting rod 416, and a ring array suction cup 418 arranged on the adjustment plate 417; the first fixing plate 43, the second fixing plate 44 and the adjustment plate 417 are all provided with through holes; 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, the moving driving motor 412 can drive the driving screw 413 to rotate, and then the moving driving screw 413 can drive the adjustment block 414 to move, and then the moving adjustment block 414 can The rotating shaft 415 is driven to move, so that the moving rotating shaft 415 can drive the fisheye bearing connecting rod 416 to move, drive the adjustment plate 417 to move, change the adjustment position, and enable the annular array suction cup 418 to adsorb the outer wall of the new pipe material, and then complete the cutting work of the new pipe material through the set cutting unit 3, and then adjust the position of the new pipe material through the cooperation of the set three supporting slide rails 411, so that the new pipe material can be sleeved on the traction tube, and then complete the heating work of the traction tube; through the set annular array suction cup 418, the annular new material is prevented from undergoing large deformation, and it is prevented that the new material is difficult to be sleeved on the traction tube, thereby ensuring the smooth heating work of the traction tube; and because the three driving motors 412 are independent of each other, the new pipe material adsorbed by the annular array suction cup 418 can be adjusted at multiple angles, so that it can be sleeved on the traction tube, and the new pipe material and the traction tube can be smoothly connected, thereby completing the heating work of the traction tube.

[0025] 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 shell 422 connected to the rotating end of the rotating part 423, a driving part and a limit seat 4210 built into the shell 422, a double-sided rack 4211 movably connected to the limit seat 4210, a movable seat 4212 connected to the double-sided rack 4211, and an extrusion roller 4213 arranged on the movable seat 4212; the axial direction of the extrusion roller 4213 is horizontal to the axial direction of the traction tube; the driving part includes a driving part built into the shell 422, and a driving part and a limit seat 4210 built into the shell 422; a double-sided rack 4211 movably connected to the limit seat 4210, a movable seat 4212 connected to the double-sided rack 4211, and an extrusion roller 4213 arranged on the movable seat 4212; the axial direction of the extrusion roller 4213 is horizontal to the axial direction of the traction tube; the driving part includes a driving part and a limit seat 4210 built into the shell 422; The mounting shaft 424 in 22, the hinge seat 425 arranged on the top of the shell 422, the driving cylinder 426 movably connected to the hinge seat 425, the first gear 427 movably connected to the output end of the driving cylinder 426 and connected to the shell 422, the rotating shaft 428 symmetrically arranged on the shell 422 and located on both sides of the limiting seat 4210, the two second gears 429 sleeved on the rotating shaft 428, and the gear ring 4214 sleeved on the mounting shaft 424; one of the second gears 429 is meshed with the double-sided rack 4211, and the other second gear 429 is meshed with the gear ring 4214; In order to make the new pipe material warm up the traction tube, after the new pipe material is sleeved on the traction tube, the telescopic cylinder 421 starts to work, and the moving telescopic cylinder 421 pushes the rotating part 423 to move, and the moving rotating part 423 can drive the shell 422 to move, so that the squeezing roller 4213 moves in the axial direction of the traction tube. After it moves a certain distance, the telescopic cylinder 421 stops working, and then the driving cylinder 426 starts to work, and the moving driving cylinder 426 drives the first gear 427 to rotate, and then the moving first gear 427 drives the second gear 429 meshing with it to rotate, and then the moving second gear 429 can drive another second gear 429 to rotate through the set rotating shaft 428, driving the double-sided gears to move in the length direction of the limit seat 4210, and then adjust the position of the movable seat 4212, so that the squeezing roller 4213 abuts against the outer wall of the new pipe material, and the remaining squeezing rollers 4213 are moved through the ring gear 4214. Driven synchronously, the rotating part 423 then drives the squeezing roller 4213 to rotate, and the new pipe material is squeezed to make it fit the traction tube, so as to complete the heating of the traction tube, so as to avoid the pipe not being able to stick to the traction tube due to the large temperature difference between the newly injected pipe and the traction tube. At the same time, the flexibility of the material is improved through heating, and the risk of rupture or damage due to force during the traction process is reduced. After the heating work is completed, the driving cylinder 426 and the telescopic cylinder 421 start to move, so that the squeezing roller 4213 is moved away from the new pipe material and the squeezing area of ​​the squeezing roller 4213 is changed. When the squeezing roller 4213 moves to a predetermined position, the driving cylinder 426 starts to work, so that the squeezing roller 4213 abuts against the outer wall of the traction tube, and then the telescopic cylinder 421 starts to work here, so that the top of the squeezing roller 4213 abuts against the diameter surface of the new pipe material, so that the new pipe material is separated from the traction tube, and then by repeating the above steps, the temperature of the traction tube is increased, and the traction tube is heated.

Since the mounting plate 39 is arranged 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; In order to transport the new material, after the cutting unit 3 completes the cutting 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 unit 3 is set to complete the cutting of the new pipe material, and then the three supporting slide rails 411 are coordinated to adjust the position of the new pipe material, so that the new pipe material can be sleeved on the traction tube, and then the traction tube is warmed up; When the new material of the pipeline is sleeved on the traction tube, the telescopic cylinder 421 starts to work, and the moving telescopic cylinder 421 pushes the rotating part 423 to move. The moving rotating part 423 can drive the shell 422 to move, so that the squeezing roller 4213 moves in the axial direction of the traction tube. After it moves a certain distance, the telescopic cylinder 421 stops working, and then the driving cylinder 426 starts to work, and the moving driving cylinder 426 drives the first gear 427 to rotate, and then the moving first gear 427 drives the second gear 429 meshing with it to rotate, and then the moving second gear 429 can drive another second gear 429 to rotate through the set rotating shaft 428, driving the double-sided gears to move in the length direction of the limit seat 4210, and then adjust the position of the movable seat 4212 to make the squeezing roller 4213 and the new material of the pipeline be meshed with each other. The outer wall of the material is abutted, and the remaining squeezing rollers 4213 are synchronously driven by the gear ring 4214, and then the rotating part 423 drives the squeezing rollers 4213 to rotate, and the new material of the pipeline is squeezed to make it fit the traction tube, so as to complete the heating of the traction tube; after the heating work is completed, the driving cylinder 426 and the telescopic cylinder 421 start to move, so that the squeezing roller 4213 is away from the new material of the pipeline and the squeezing area of ​​the squeezing roller 4213 is changed. When the squeezing roller 4213 moves to a predetermined position, the driving cylinder 426 starts to work, so that the squeezing roller 4213 is abutted against the outer wall of the traction tube, and then the telescopic cylinder 421 starts to work again, so that the top of the squeezing roller 4213 is abutted against the diameter surface of the new material of the pipeline, so that the new material of the pipeline is separated from the traction tube, and then by repeating the above steps, the temperature of the traction tube is increased, and the traction tube is heated; When the first actuator and the second actuator are required to work, the actuator motor 21 starts to work, and the moving actuator motor 21 can drive the rotating seat 23 to rotate, thereby driving the movable shaft 24 to move, and 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, and the moving fourth gear 27 can drive the connecting shaft 28 to rotate. At this time, the moving connecting shaft 28 can drive the first actuator and the second actuator to move, thereby driving the hammer rod 212 to perform a predetermined movement, completing the cleaning or hole opening work of the solidified plastic, and ensuring the smooth discharge of the gas in the extruder 1; when the connecting shaft 28 starts to rotate, the moving connecting shaft 28 can drive the cam 29 to move, and the moving cam 29 can drive the actuator rod 210 to move. Thereby, the driven rod 211 and the hammer rod 212 can be driven to move in the axial direction thereof, so that the hammer rod 212 can impact the solidified plastic; when the connecting shaft 28 starts to rotate, the moving connecting 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, and 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, and then the rotating rod 218 can be driven to rotate, and the fifth gear 219 can be driven to rotate, and then the moving fifth gear 219 can drive the sixth gear 25 to rotate, and the moving sixth gear 25 drives the hammer rod 212 to rotate, so that the hammer rod 212 can open a hole in the solidified plastic, thereby ensuring the smooth progress of the gas discharge work.
