Description

Technical Field

[0001] This application relates to the field of pipe manufacturing technology, and specifically discloses a high-speed composite material pipe continuous production line. Background Technology

[0002] High-speed fiber-reinforced composite pipes are made by continuously arranging and weaving high-strength glass fibers in the warp and weft directions using a winding machine. The specific structure consists of an inner lining layer, a transition layer arranged in the weft direction, and an outer lining layer. These three layers are integrated after being impregnated with adhesive. They possess advantages such as high strength, high impact resistance, corrosion resistance, light weight, high toughness, ease of construction, convenient maintenance, low overall cost, long service life, and high safety.

[0003] Chinese invention patent CN106378924B discloses a method for manufacturing a fiber-reinforced lining composite pipe. The method involves using an inner lining pipe as an internal support, simultaneously winding fiber reinforcement material around the outside of the inner lining pipe to form a reinforcement layer; while forming the reinforcement layer on the outer surface of the inner lining pipe, simultaneously winding protective decorative material around the reinforcement layer to form a protective decorative layer, thereby processing the inner lining pipe into a composite pipe; and performing post-processing on the composite pipe to produce a fiber-reinforced lining composite pipe that meets the requirements.

[0004] Similarly, Chinese invention patent CN112829335A discloses a high-speed composite material pipeline continuous production line, including a main unit, a coated axial yarn disc device, a film limiting plate device 1, and a mold. Two sets of support devices 1 are provided at the end of the mold away from the main unit. An axial yarn feeding device is provided at the end of the support device 1 away from the main unit. Four sets of circumferential yarn feeding devices 1 are provided on both sides of the coated axial yarn disc device and on both sides in the middle of the two sets of support devices 1. A second circumferential yarn feeding device and a second film limiting plate device 2 are provided at the end of the axial yarn feeding device away from the main unit. A surface sealing device is provided at the top of the second film limiting plate device. A heating and curing device, a cooling device, a second support device, a rotary traction machine, an automatic cutting device, and an automatic unloading device are provided at the end of the second circumferential yarn feeding device away from the axial yarn feeding device.

[0005] In the existing production model, high-speed fiber-reinforced composite pipes are typically mass-produced using the following steps: the production mold and the inner liner are rotated and moved axially by a rotary traction machine, while multiple sets of high-strength glass fibers are woven and wound along the surface of the inner liner under the action of multiple winding machines. After weaving and winding, the pipe undergoes processes such as applying adhesive, drying and curing, cooling and molding, and cutting to form high-speed fiber-reinforced composite pipe products of a certain specification.

[0006] During this production process, because the cooled pipes are still driven by the rotary traction machine to rotate and move axially, the cutting machine needs to maintain synchronous axial movement with the pipe to form a flat cut end face. Furthermore, high-speed fiber-reinforced composite pipes require equal-length and equal-distance cutting during production; that is, the cutting machine is not constantly in a cutting state. When not cutting the pipe, the cutting machine needs to be disengaged from the pipe to avoid damage to the pipe surface. In Chinese invention patent CN112829335A, two ball screw pairs are used to adjust the cutting machine's axial movement along the pipe. While contact cutting of pipes by a cutting machine can achieve the desired cutting effect, this method places high demands on the precision of the two ball screw pairs, their drive mechanisms, and control systems. It is complex to control, has high equipment costs, low stability, and high maintenance expenses. Furthermore, the cutting process does not address the resulting debris. For large-diameter pipes, a single cut can generate a large amount of powder and debris. If this debris is not handled promptly, it will affect the normal operation of the ball screw pairs and other components in the production line, thereby reducing the quality of the finished pipe. Therefore, the inventors have proposed a high-speed composite material pipe continuous production line to solve these problems. Summary of the Invention

[0007] The purpose of this invention is to solve the problem of increased production and maintenance costs in the traditional production process of high-speed fiber-reinforced composite pipes, which requires the use of two ball screw pairs to separately adjust the axial movement of the cutting machine along the pipe and the contact between the cutting machine and the pipe.

[0008] To achieve the above objectives, the basic solution of the present invention provides a high-speed composite material pipeline continuous production line, comprising a rotary traction machine, several winding machines, an adhesive applicator, a heating and curing device, a cooling device, and a cutting machine arranged in sequence, characterized in that: it further includes an adjustment mechanism for adjusting the position of the cutting machine;

[0009] The adjustment mechanism includes a power component, a ball screw pair driven by the power component, and a slide block moved by the ball screw pair. The slide block has a cavity, and a mounting base for mounting a cutting machine is vertically slidably connected in the cavity. A rotating shaft is rotatably connected in the cavity, and a lifting cam is provided on the rotating shaft. The lifting cam has a continuously transitioning outer wheel surface and an inner wheel surface. It also includes an adjustment shaft driven to rotate by the power component. Several locking strips are evenly provided on the surface of the adjustment shaft along the axial direction. One end of the rotating shaft passes through the slide block and is provided with an adjustment gear that meshes with the locking strips. An internal ratchet mechanism is provided between the adjustment gear and the rotating shaft for transmission.

[0010] The principle and effect of this basic scheme are as follows:

[0011] 1. In this invention, the mounting seat is brought into contact with the outer and inner wheel surfaces of the lifting cam by the rotation of the lifting cam. When the mounting seat is in contact with the outer wheel surface of the lifting cam, the mounting seat is lifted by the lifting cam, allowing the cutting machine to contact the pipe and perform cutting. When the mounting seat is in contact with the inner wheel surface of the lifting cam, the mounting seat descends under its own weight, causing the cutting machine to disconnect from the pipe. This does not interfere with the normal rotation and axial movement of the pipe during production and avoids the cutting machine damaging the surface of the pipe.

[0012] 2. In this invention, an internal ratchet mechanism is provided between the adjusting gear and the rotating shaft for transmission, so that when the adjusting gear rotates in the forward direction, it can drive the rotating shaft to rotate, while when the adjusting gear rotates in the reverse direction, the rotating shaft remains stationary, which meets the needs of the application scenario in the pipe cutting process.

[0013] 3. In this invention, the power component drives the ball screw pair and the adjusting shaft to rotate. The ball screw pair causes the slide to slide, which in turn causes the cutting machine to slide. At the same time, the retaining strip on the adjusting shaft meshes with the adjusting gear, causing the rotating shaft to rotate, which in turn causes the lifting cam to rotate, causing the mounting base to rise and fall, which allows the cutting machine to move closer to or away from the pipe.

[0014] 4. Compared with the prior art, the present invention uses a unified power component to simultaneously control the axial movement of the cutting machine and the contact between the cutting machine and the pipe, making control and adjustment more convenient and faster, and reducing installation and maintenance costs. Furthermore, the lifting of the cutting machine is driven by a purely mechanical lifting cam, which ensures greater structural strength and stability, further reducing maintenance time and costs and improving production efficiency.

[0015] Furthermore, the mounting base includes a base slidably connected to the cavity, a protective box, a recycling box, and a collection box located on top of the base. The cutting machine includes a drive motor mounted on top of the protective box and a cutting blade driven by the drive motor. The recycling box has a recycling funnel located below the cutting blade on top. The recycling box has an air chamber communicating with the recycling funnel. A main shaft is rotatably connected inside the protective box. One end of the main shaft extends into the air chamber and has a fan wheel. A filter screen is provided inside the recycling funnel. A material guiding pipe is provided between the side wall of the recycling funnel and the collection box. The connection between the material guiding pipe and the recycling funnel is on the same horizontal line as the filter screen. During operation, the cutting machine requires a drive motor to rotate the cutting blade at high speed. By setting a main shaft, the drive motor rotates the cutting blade at high speed while simultaneously rotating the main shaft, which in turn drives the impeller inside the air chamber to rotate at high speed. This creates a pressure difference between the air chamber and the outside environment, generating suction at the end of the recovery funnel. This suction draws air from outside the recovery funnel into the air chamber, carrying the debris generated during the cutting process into the recovery funnel. After being filtered by the filter screen, the debris is retained on the filter screen, thus achieving the recovery of debris and the separation of debris from air. This prevents debris from affecting the normal operation of the ball screw assembly and other components in the production line.

[0016] Furthermore, the main shaft is fixedly connected to a grooved cam located inside the protective box. The surface of the grooved cam has a groove that smoothly transitions along the axial position of the main shaft. Above the grooved cam is a guide rod that is slidably connected to the protective box. The end of the guide rod extends into the recovery funnel and has a push head that can be pushed along the surface of the filter screen. A connecting rod is fixedly connected to the guide rod, and the bottom of the connecting rod is slidably connected in the groove. While the main shaft drives the impeller to rotate, it also drives the grooved cam to rotate. The cooperation between the grooved cam and the connecting rod allows the grooved cam to drive the connecting rod to perform axial reciprocating motion when rotating, which in turn drives the guide rod to perform axial reciprocating motion, and drives the push head to reciprocate on the surface of the filter screen. This can promptly push the debris on the filter screen into the guide pipe, and then into the collection box for centralized collection, preventing debris from clogging the filter screen and affecting the suction force generated by the impeller.

[0017] Furthermore, a ball bearing is fixedly attached to the bottom of the connecting rod, and the ball bearing is slidably connected to the groove. The ball bearing engages the connecting rod with the groove, reducing the contact area between them, thereby reducing friction and minimizing wear and heat generation during operation.

[0018] Furthermore, the side wall of the recovery funnel is provided with a guide frame, and the push head is slidably connected to the guide frame. The guide frame can support, limit, and guide the reciprocating motion of the push head, while improving the sealing performance of the recovery funnel and preventing debris leakage.

[0019] Furthermore, the bottom of the push head is provided with several brush teeth that can brush along the surface of the filter screen. Driven by the push head, the brush teeth brush along the surface of the filter screen, further preventing debris from clogging the filter screen.

[0020] Furthermore, a reset assembly is provided between the base and the bottom of the cavity. The reset assembly can improve the reset effect of the base. The base's own weight and the reset assembly work together to reset the base, enabling timely adjustment of the base's position.

[0021] Furthermore, the reset assembly includes a fixed sleeve fixedly connected to the bottom of the base, a fixed shaft fixedly connected to the bottom of the cavity and slidably connected to the fixed sleeve, and a reset spring disposed between the base and the bottom of the cavity. The fixed sleeve and fixed shaft can limit the sliding of the base, preventing the base from shifting position and improving the cutting accuracy, while the reset spring facilitates timely reset of the base.

[0022] Furthermore, the drive motor is a dual-axis motor. One output shaft of the dual-axis motor is connected to the cutting blade, and the other output shaft is connected to the main shaft via a belt drive. Using a dual-axis motor effectively reduces the distance between the end of the drive motor and the cutting blade, reducing blade runout and improving blade stability during operation.

[0023] Furthermore, two rotating shafts and two lifting cams are symmetrically arranged within the cavity, and a synchronous belt mechanism connects the two rotating shafts. The use of two rotating shafts and lifting cams ensures that the base achieves force balance, further improving stability. Attached Figure Description

[0031] A high-speed fiber-reinforced composite pipe production line 14 includes a rotary traction machine, at least two winding machines, an adhesive applicator, a heat curing device, a cooling device, and a cutting machine arranged sequentially. The rotary traction machine drives the production mold and inner liner to rotate and move axially. Simultaneously, multiple sets of high-strength glass fibers are wound along the surface of the inner liner under the action of multiple winding machines. Then, the adhesive applicator, heat curing device, and cooling device respectively apply adhesive, dry and cure, and cool the wound pipe 14. In this embodiment, the rotary traction machine, winding machine, adhesive applicator, heat curing device, and cooling device are all readily available in mature existing materials, such as those published in CN106378924B and CN112829335A, and will not be elaborated upon here. The cutting machine in this embodiment is provided by... Figure 1 The adjustment mechanism shown is driven and controlled as follows:

[0032] The adjustment mechanism includes an axial adjustment component and a longitudinal adjustment component. The axial adjustment component includes a power motor 2, a ball screw pair, and a slide 7. The power motor 2 and the ball screw pair are both installed on the workbench 1 or the floor of the production line. The power motor 2 drives the lead screw 3 in the ball screw pair to rotate. The slide 7 is connected to the nut seat in the ball screw pair. When the lead screw 3 rotates, the slide 7 slides along the axial direction of the lead screw. On the workbench 1 or the floor of the production line, two support rails 4 are symmetrically arranged on both sides of the lead screw 3. Two guide sleeves 9 are symmetrically arranged on both sides of the lead screw 3 at the bottom of the slide 7. The guide sleeves 9 are slidably connected to the support rails 4. The support rails 4 support the slide 7 and limit and guide the sliding of the slide 7. The pipe 14 rotates and moves along the axial direction under the drive of the rotary traction machine. The lead screw 3 drives the slide 7 to keep the axial movement synchronized with the pipe 14, and the sliding distance of the slide 7 is greater than the axial distance traveled by the pipe 14 when it rotates one revolution.

[0033] The longitudinal adjustment assembly includes an adjustment shaft 5 and a lifting cam 19. The adjustment shaft 5 is arranged parallel to the lead screw 3 and is connected to the output shaft of the power motor 2 via a synchronous belt mechanism. Specifically, two synchronous pulleys are connected to the output shaft of the power motor 2 and the adjustment shaft 5, respectively. The two synchronous pulleys are driven by a synchronous belt, so that the output shaft of the motor can drive the adjustment shaft 5 to rotate synchronously. Several retaining strips 6 are axially arranged on the side of the adjustment shaft 5. The cross-section of the retaining strips 6 and the adjustment shaft 5 form a complete gear shape. An adjustment gear 8 is rotatably connected to the side wall of the slide 7. The adjustment gear 8 meshes with the retaining strips 6, so that the adjustment shaft 5 can drive the adjustment gear 8 to rotate at the same time. The length of the retaining strips 6 is greater than the axial movement distance of the slide 7 to prevent the retaining strips 6 from disengaging from the adjustment gear 8. The number of teeth of the adjustment gear 8 is greater than the number of retaining strips 6 to achieve the effect of speed reduction transmission.

[0034] like Figure 2 and Figure 3 As shown: The slide 7 has a cavity, and a mounting base for mounting a cutting machine is vertically slidably connected within the cavity. Two rotating shafts 15 are rotatably connected between the mounting base and the inner bottom surface of the cavity. The two rotating shafts 15 are symmetrically arranged within the cavity and parallel to the adjusting shaft 5. Two lifting cams 19 are respectively mounted on the two rotating shafts 15. The two rotating shafts 15 are also connected by a synchronous belt mechanism to ensure the synchronicity of their movement. The adjusting gear 8 is connected to one of the rotating shafts 15 via an internal ratchet mechanism, as detailed below. Figure 2As shown, the adjusting gear 8 is coaxially connected to a rotating wheel 17, and a ratchet 16 is provided on the rotating shaft 15. The inner wall of the ratchet 16 is evenly provided with several ratchet teeth. The rotating wheel 17 is provided with a pawl 18 that cooperates with the ratchet teeth. The pawl 18 and the rotating wheel 17 are provided with an elastic connecting member at the center, so that when the adjusting gear 8 rotates in the forward direction, it can drive the rotating shaft 15 to rotate, while when the adjusting gear 8 rotates in the reverse direction, the rotating shaft 15 remains stationary.

[0035] like Figure 3 As shown, the lifting cam 19 has a continuously transitioning outer and inner wheel surface. The lifting mechanism rotates under the drive of the rotating shaft 15. When the mounting seat contacts the outer wheel surface of the lifting cam 19, the mounting seat is lifted by the lifting cam 19, allowing the cutting machine to contact the pipe 14 for cutting. When the mounting seat contacts the inner wheel surface of the lifting cam 19, the mounting seat descends under its own weight, causing the cutting machine to disconnect from the pipe 14, thus not interfering with the normal rotation and axial movement of the pipe 14 during production and preventing the cutting machine from damaging the surface of the pipe 14. When the slide 7 slides for one cycle... The contact point between the lifting cam 19 and the mounting base changes in a cycle from the inner wheel surface to the outer wheel surface and back to the inner wheel surface. This is achieved by setting the number of locking bars 6 and adjusting gears 8, so that when the slide 7 completes one cycle of movement, the lifting cam 19 rotates one revolution. Furthermore, the period of contact time between the outer wheel surface of the lifting cam 19 and the mounting base is the same as the period of time required for the pipe 14 to rotate one revolution. During actual cutting, the slide 7 and the lifting cam 19 are in their initial positions, the mounting base is in contact with the inner wheel surface of the lifting cam 19, and is in a lower position. The cutting machine is not in contact with the pipe 14. The power motor 2 drives the lead screw 3 and adjusts... Shaft 5 and adjusting gear 8 rotate in the forward direction. Adjusting gear 8 drives rotating shaft 15 in the forward direction through internal ratchet mechanism, causing lifting cam 19 to rotate in the forward direction, lifting the mounting seat and holding it in the highest position. At this time, the cutting machine contacts pipe 14 and can cut pipe 14. After pipe 14 rotates one revolution, the cutting of pipe 14 is completed. At this time, the lifting cam 19 transitions from contact between the outer wheel surface and the mounting seat to contact between the inner wheel surface and the mounting seat. During the transition, slide 7 still moves in the forward direction, so that there is a buffer distance between the cutting machine and pipe 14, avoiding damage to the surface of pipe 14 by the cutting machine during the process. Once the cutting is complete and the lifting cam 19 has fully transitioned, the slide 7 and the lifting cam 19 return to their initial positions. The mounting base contacts the inner wheel surface of the lifting cam 19 and is in a lower position. The power motor 2 drives the lead screw 3, adjusting shaft 5, and adjusting gear 8 to rotate in the opposite direction, causing the slide 7 to return to its initial position. During this process, due to the internal ratchet mechanism, although the adjusting gear 8 rotates, the adjusting shaft 5 and the lifting cam 19 remain stationary. That is, the cutting machine is always in the lowest position, which does not interfere with the normal rotation and axial movement of the pipe 14 during production, thus preventing the cutting machine from damaging the surface of the pipe 14.

[0036] To improve the reset performance of the mounting base, multiple reset components are provided between the mounting base and the bottom of the cavity. The reset components include a fixed sleeve 20 fixed to the bottom of the mounting base, a fixed shaft 21 fixed to the bottom of the cavity and slidably connected to the fixed sleeve 20, and a reset spring 22 provided between the mounting base and the bottom of the cavity. The reset spring 22 is sleeved on the surface of the fixed sleeve 20 and the fixed shaft 21, reducing the installation space required.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, the mounting base includes a base 10 slidably connected to the cavity, a protective box 11 on top of the base 10, a recycling box 30, and a collection box 35. The cutting machine includes a drive motor 12 mounted on top of the protective box 11 and a cutting blade 13 driven by the drive motor 12. The drive motor 12 is a dual-axis motor. The top of the recycling box 30 has a recycling funnel 23 located below the cutting blade 13. The recycling box 30 has an air chamber communicating with the recycling funnel 23. An air outlet is provided on the side wall of the air chamber. A main shaft 24 is rotatably connected inside the protective box 11. 24 is driven by the drive motor 12 to rotate. Specifically, one output shaft of the dual-axis motor is connected to the cutting blade 13, and the other output shaft of the dual-axis motor is connected to the main shaft 24 by belt drive. One end of the main shaft 24 extends into the air cavity and is equipped with a fan wheel 31. A filter screen is provided in the recycling funnel 23. An inclined guide pipe 34 is provided between the side wall of the recycling funnel 23 and the collection box 35. The position where the guide pipe 34 connects to the recycling funnel 23 is located at the highest point, and the connection between the guide pipe 34 and the recycling funnel 23 is on the same horizontal line as the filter screen.

[0038] like Figure 4 As shown, a grooved cam 25 is fixedly connected to the main shaft 24 and located inside the protective box 11. The surface of the grooved cam 25 has a groove 27 that changes smoothly along the axial position of the main shaft 24. Above the grooved cam 25 is a guide rod 26 that is slidably connected to the protective box 11. The end of the guide rod 26 extends into the recovery funnel 23 and is provided with a push head 32 that can be pushed along the surface of the filter screen. A connecting rod 28 is fixedly connected to the guide rod 26. A ball bearing 29 is fixedly connected to the bottom of the connecting rod 28. The ball bearing 29 is slidably connected to the groove 27. A guide frame 33 is provided on the side wall of the recovery funnel 23. The push head 32 is slidably connected to the guide frame 33. The bottom of the push head 32 is provided with several brush teeth that can brush the surface of the filter screen. Figure 4 To facilitate the display of the internal structure, the sides of the recycling bin 30, recycling funnel 23 and guide frame 33 are partially cut apart. It should be understood that the recycling bin 30, recycling funnel 23 and guide frame 33 are complete structural shapes.

[0039] In this embodiment, while the drive motor 12 drives the cutting blade 13 to rotate at high speed, it can also drive the main shaft 24 to rotate at high speed. Not only can the high-speed rotation of the impeller 31 generate suction to absorb the debris generated during the cutting process, but the cooperation of the grooved cam 25, the connecting rod 28 and the guide rod 26 can also cause the push head 32 to reciprocate on the surface of the filter screen, pushing the debris on the filter screen into the guide pipe 34, preventing the debris from clogging the filter screen. Moreover, the use of a dual-axis motor can meet the need to drive the cutting blade 13 and the main shaft 24 to rotate at the same time, which can effectively reduce the distance between the end of the drive motor 12 and the cutting blade 13, reduce the jump of the cutting blade 13, and improve the stability of the cutting blade 13 during operation.

[0040] Compared with the prior art, the present invention uses a unified power component to simultaneously control the axial movement of the cutting machine and the contact between the cutting machine and the pipe 14, making control and adjustment more convenient and faster, and reducing installation and maintenance costs. Furthermore, the lifting of the cutting machine is driven by a purely mechanical lifting cam 19, which ensures structural strength and stability, further reducing maintenance time and costs and improving production efficiency. Moreover, it can collect and process the debris generated during the cutting process in a timely manner, preventing the debris from affecting the normal operation of the ball screw pair and other components in the production line.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
