Description

Technical Field

[0001] This utility model belongs to the field of cooling and feeding technology for steel pipe extruders, and specifically relates to a vibration device for cooling and feeding steel pipe extruders. Background Technology

[0002] The steel pipe extruder is the core equipment in a plastic pipe production line, mainly used for the continuous molding of various thermoplastic pipes (such as PVC, PE, PPR pipes, etc.). Its working principle involves heating and melting plastic granules, then extruding them under pressure through a screw system. The molten plastic is forced through a precision die with an annular slit, forming a continuous hollow tubular preform. Subsequently, the preform undergoes vacuum shaping and a cooling water bath for solidification and shaping. It is then uniformly pulled out by a traction device and finally cut to a fixed length by a cutting device to obtain finished pipes with uniform specifications and smooth surfaces. This equipment integrates plasticizing, extrusion, shaping, cooling, traction, and cutting functions, and is widely used in the manufacturing of pipeline systems in the construction, municipal, agricultural, and industrial fields.

[0003] After extrusion molding, a relatively static "hot water boundary layer" forms on the surface of the pipe as it is transported along the guide rail. This hot water layer acts like an insulation layer attached to the pipe wall, significantly hindering the efficient transfer of heat from the inside of the pipe to the flowing cooling water, thus reducing the overall heat exchange efficiency. This problem not only affects the uniformity and speed of cooling but also adversely impacts subsequent conveying and unloading processes.

[0004] To address the aforementioned issues, this application proposes a cooling and feeding vibration device for a steel pipe extruder. Utility Model Content

[0005] To address the aforementioned problems in the existing technology, this utility model provides a cooling and feeding vibration device for a steel pipe extruder, which features stable conveying.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cooling and feeding vibration device for a steel pipe extruder, including a guide channel and a vibration mechanism, wherein the vibration mechanism is disposed at the bottom of the guide channel and a spraying mechanism is disposed inside the guide channel; The vibration mechanism includes: A support base is fixedly connected to the bottom of the guide channel. A motor is fixedly connected to the bottom of the support base. A worm gear is fixedly connected to the output end of the motor. A worm wheel meshes with the outer wall of the worm gear. A long shaft is fixedly connected to the inner ring of the worm wheel. An irregular gear is fixedly connected to the outer wall of the long shaft. A rack meshes with the outer ring of the irregular gear. A connecting arm is fixedly connected to the outer side of the rack. A fixing arm is fixedly connected to the bottom of the guide channel.

[0007] Preferably, a long box is fixedly connected to the inner side of the fixed arm. A spring is fixedly connected to the inner wall of the long box, a rectangular plate is fixedly connected to the top of the spring, a support plate is fixedly connected to the bottom of the guide channel, and a vibration shaft is fixedly connected to the top of the rectangular plate.

[0008] Preferably, a rectangular opening is provided on one side of the long box, and the connecting arm passes through the rectangular opening and moves, so that the connecting arm can move through the rectangular opening.

[0009] Preferably, the rectangular plate is slidably connected to the inner wall of the long box, and the connecting arm is fixedly connected to the outer side of the rectangular plate, so that the rectangular plate can move stably to compress the spring.

[0010] Preferably, the top of the long box has a circular hole, through which the vibration shaft passes and moves, allowing the vibration shaft to move through the circular hole.

[0011] Preferably, the support plate has a rotating hole inside, and the long shaft is rotatably connected to the inner wall of the rotating hole to provide stable support for the long shaft.

[0012] Preferably, the spraying mechanism includes a support pipe, which is fixedly connected inside the guide channel. One end of the support pipe is fixedly connected to a conveying pipe, and the end of the support pipe away from the conveying pipe is fixedly connected to a nozzle. A diversion pipe is fixedly connected to the bottom of the conveying pipe, and an installation pipe is fixedly connected to the outer wall of the diversion pipe, so that the cooling water can be stably conveyed.

[0013] Preferably, the installation pipe, the diversion pipe, the delivery pipe, the support pipe, and the inner wall of the nozzle are connected in sequence, so that the water source can be delivered to the inside of the nozzle for spraying.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, an irregular gear and rack meshing mechanism driven by a motor, combined with a spring reset device, achieves continuous and stable reciprocating vibration of the vibrating shaft on the bottom of the guide channel. This mechanical vibration effectively breaks the static water film and hot water boundary layer at the contact surface between the pipe and the guide channel, significantly enhancing the heat exchange efficiency between the cooling water and the pipe wall. This not only avoids pipe deformation caused by uneven cooling but also increases the cooling speed, providing a good foundation for subsequent conveying and unloading processes.

[0015] 2. In this utility model, by rationally connecting the installation pipe, the diversion pipe, and multiple sets of nozzles, a uniform and stable water curtain coverage is formed. Simultaneously, high-frequency micro-vibration is applied to the guide channel, causing continuous micro-displacement of the pipe during transport, preventing prolonged contact between the pipe and the channel body and the resulting cooling dead zones. This design significantly improves the uniformity of pipe cooling and overall production efficiency, while also being structurally reliable, easy to install and maintain, and possessing high practical value.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figures 1-5 The present invention provides the following technical solution: a cooling and feeding vibration device for a steel pipe extruder, including a guide channel 1, and further including a vibration mechanism 2. The vibration mechanism 2 is disposed at the bottom of the guide channel 1, and a spraying mechanism 3 is disposed on the inner side of the guide channel 1. By integrating the vibration mechanism 2 at the bottom of the guide channel 1 and working in coordination with the spraying mechanism 3, continuous vibration is achieved during the pipe cooling process, which effectively destroys the static hot water boundary layer on the surface of the pipe, significantly improves the cooling uniformity and heat exchange efficiency, and provides smooth conditions for subsequent feeding. Vibration mechanism 2 includes: A support base 21 is fixedly connected to the bottom of the guide channel 1. A motor 22 is fixedly connected to the bottom of the support base 21. A worm gear 23 is fixedly connected to the output end of the motor 22. A worm wheel 24 meshes with the outer wall of the worm gear 23. A long shaft 25 is fixedly connected to the inner ring of the worm wheel 24. An irregular gear 27 is fixedly connected to the outer wall of the long shaft 25. A rack 28 meshes with the outer ring of the irregular gear 27. A connecting arm 29 is fixedly connected to the outer side of the rack 28. A fixed arm 202 is fixedly connected to the bottom of the guide channel 1. The motor 22 drives the worm gear 23 and worm wheel 24 to rotate the irregular gear 27. Combined with the rack 28 and the spring 204 reset structure, the vibration shaft 205 achieves stable and continuous up-and-down reciprocating motion. The structure is reliable and the transmission efficiency is high, effectively avoiding the problems of excessive impact or discontinuous action that may occur in traditional pneumatic or hydraulic vibration.

[0021] Preferably, a long box 203 is fixedly connected to the inner side of the fixed arm 202. A spring 204 is fixedly connected to the inner wall of the long box 203, a rectangular plate 201 is fixedly connected to the top of the spring 204, a support plate 26 is fixedly connected to the bottom of the guide channel 1, and a vibration shaft 205 is fixedly connected to the top of the rectangular plate 201.

[0022] Furthermore, a rectangular opening is provided on one side of the long box 203, through which the connecting arm 29 passes and moves. The rectangular opening precisely limits the movement trajectory of the connecting arm 29, ensuring the stability of the meshing and disengagement process between the rack 28 and the irregular gear 27, and improving the reliability and repeatability of the vibration action.

[0023] Furthermore, the rectangular plate 201 is slidably connected to the inner wall of the long box 203, and the connecting arm 29 is fixedly connected to the outer side of the rectangular plate 201, so that the rectangular plate 201 can move stably to compress the spring 204. The rectangular plate 201 slides along the inner wall of the long box 203, ensuring that it will not deflect during the compression and release of the spring 204, so that the spring force can act perpendicularly on the vibration shaft 205, ensuring the linearity and efficiency of the vibration force transmission.

[0024] Furthermore, a circular hole is provided at the top of the long box 203, through which the vibration shaft 205 passes and moves. The circular hole guides and limits the vibration shaft 205, ensuring that it performs precise up-and-down reciprocating motion in the vertical direction, preventing radial sway, and allowing the vibration energy to be transmitted more concentratedly to the guide groove 1, thereby improving the vibration effect.

[0025] Furthermore, the support plate 26 has a rotating hole inside, and the long shaft 25 is rotatably connected to the inner wall of the rotating hole. The support plate 26 and its rotating hole provide stable support for the long shaft 25, effectively reducing the radial runout of the long shaft 25 when rotating at high speed, ensuring the smooth meshing of the irregular gear 27 and the rack 28, and extending the service life of the mechanism.

[0026] Furthermore, the spraying mechanism 3 includes a support pipe 32, which is fixedly connected inside the guide channel 1. One end of the support pipe 32 is fixedly connected to a conveying pipe 31, and the other end of the support pipe 32 away from the conveying pipe 31 is fixedly connected to a nozzle 33. A diversion pipe 34 is fixedly connected to the bottom of the conveying pipe 31, and an installation pipe 35 is fixedly connected to the outer wall of the diversion pipe 34. The cooling water source is connected through the diversion pipe 34 and the installation pipe 35, and the water is conveyed to the nozzle 33 through the conveying pipe 31 and the support pipe 32, forming a stable cooling water conveying path. This ensures sufficient and continuous supply of coolant, providing a foundation for efficient heat dissipation.

[0027] Furthermore, the inner walls of the installation pipe 35, the diversion pipe 34, the delivery pipe 31, the support pipe 32, and the nozzle 33 are connected in sequence. The sequential connection of each level of pipes forms a complete spray circuit, ensuring that the cooling water can be sprayed out from the nozzle 33 evenly and stably, forming a comprehensive water curtain. This works in conjunction with the vibration mechanism 2 to achieve efficient and uniform cooling of the pipe.

[0028] Components not described in detail in this article are existing technologies.

[0029] The working principle and usage process of this utility model are as follows: First, the guide channel 1 is installed at the feeding position of the steel pipe extruder. Then, it can be connected to the cooling pipe through the installation pipe 35. Then, the cooling water can be output to the inside of the nozzle 33 through the diversion pipe 34, the conveying pipe 31 and the support pipe 32, so as to spray and cool the feeding pipe of the steel pipe extruder, and ensure the stability of the cooling of the pipe.

[0030] When the motor 22 starts, it drives the worm 23 to rotate. The worm 23 meshes with the worm wheel 24, which in turn drives the long shaft 25 to rotate via the worm wheel 24. The long shaft 25 can drive the irregular gear 27 to rotate. When the irregular gear 27 is not meshing with the rack 28, it is under compression. The spring 204 pushes the rectangular plate 201 to move the vibration shaft 205, allowing the vibration shaft 205 to contact the bottom of the guide channel 1. Since the rotation of the irregular gear 27 is continuous, the vibration shaft 205 will reciprocate up and down to strike and vibrate the guide channel 1, preventing the pipe from constantly sticking to the guide channel 1 and ensuring that the cooling water can stably dissipate heat and cool the outer wall of the pipe.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
