Description

Technical Field

[0001] This invention belongs to the field of fiberglass composite pipe production equipment, and specifically relates to a fiberglass composite pipe production system. Background Technology

[0002] Fiberglass composite pipe is a type of pipe made of glass fiber and organic polymer materials. It has the characteristics of being lightweight, corrosion resistant, flame retardant, and insulating. Fiberglass composite pipe has excellent physical and mechanical properties, which can meet the transportation needs in various complex environments. At the same time, it has a long service life and low maintenance costs.

[0003] Fiberglass composite pipes are typically produced using a winding method. In existing production systems, the winding equipment usually requires lifting the mold onto the winding equipment. During the handling process, mechanical equipment is needed for lifting and handling, which is cumbersome and poses safety hazards. Furthermore, in existing production systems, the pipes are usually stacked, and when removing a pipe, it is necessary to start from the top layer. This is not only inconvenient due to the height, but also prone to causing the pipe stack to collapse. Summary of the Invention

[0042] The present invention provides the following embodiments.

[0043] Example 1

[0044] This invention provides a fiberglass composite pipe production system, such as... Figure 1-11 As shown, it includes: a base plate 1, a rotating assembly 2 on the base plate 1, the rotating assembly 2 being used to rotate and wind fiberglass composite material to make pipes, an extruder on one side of the rotating assembly 2, and a shaft unloading assembly 4 on the other side of the rotating assembly 2, the shaft unloading assembly 4 being used to unload the finished pipes and molds, a temporary storage assembly 5 on the other side of the shaft unloading assembly 4, the temporary storage assembly 5 being used to store the pipes and deliver them in batches, a cutting assembly 6 at the conveying end of the temporary storage assembly 5, the cutting assembly 6 being used to cut the edges of the fiberglass composite pipes, and also includes an eccentricity detection assembly, the eccentricity detection assembly being used to monitor the eccentricity of the rotating assembly 2 in real time.

[0045] The working principle and beneficial effects of the above technical solution are as follows: When making pipes, the extruder extrudes PE sheet strips and attaches them to the rotating component 2. Then, the rotating component 2 is started. After the rotating component 2 finishes making the pipe, the unloading component 4 removes the mold on the rotating component for demolding. The demolded fiberglass composite pipe is placed into the temporary storage component 5. The temporary storage component 5 releases the fiberglass composite pipes one by one and enters the cutting component 6 to cut both ends of the fiberglass composite pipe. The eccentricity detection component is used to detect the rotation of the rotating component 2 to ensure the production quality of the fiberglass composite pipe.

[0046] This invention utilizes a rotating component 2 to produce fiberglass composite tubes. This design reduces the height of the cantilever 23 by rotating, thereby reducing the installation height of the mold and simplifying the installation process. No mechanical support is required; manual installation is assisted only by tools, reducing installation risks and preventing accidents. The unloading component 4 eliminates the need for manual unloading, employing semi-automatic unloading to improve work efficiency. The temporary storage component 5 allows for batch delivery of pipes, preventing issues such as high stack height hindering operation and pipe collapse during retrieval. The cutting component 6 ensures uniform core tube length, facilitating unified management in subsequent production processes, while providing a smooth cut surface that eliminates the need for secondary pipe trimming. The eccentricity detection component prevents uneven fiberglass winding in the core tubes due to wear and tear after prolonged production, which could lead to increased eccentricity after prolonged use.

[0047] Example 2

[0048] Based on embodiment 1, the rotating assembly 2 includes a frame 21, an electric rotating shaft 22 rotatably connected to the frame 21, a cantilever 23 splinedly connected to both ends of the electric rotating shaft 22, a hydraulic cylinder 24 sleeved on the electric rotating shaft 22, the two ends of the hydraulic cylinder 24 being connected to the cantilever 23 at the left and right ends respectively, the cantilever 23 sliding relative to the electric rotating shaft 22, an electric rotating shaft 25 installed at the other end of the cantilever 23, and a steel mold shaft 26 installed at the working end of the electric rotating shaft 25 through the connecting structure 3.

[0049] The connecting structure 3 includes a bearing seat 31, which is installed at the output end of the electric rotating shaft 25. The bearing seat 31 is provided with a slot 32. A fixing plate 33 is rotatably connected to the bearing seat 31. A wedge plate 34 is fixed below the fixing plate 33. The wedge plate 34 and the slot 32 cooperate with each other. A steel mold shaft 26 is nested inside the bearing seat 31. The two ends of the steel mold shaft 26 are respectively provided with wedge grooves 35. The wedge grooves 35 and the wedge plate 34 correspond one-to-one and cooperate with each other. A U-shaped clip 36 is rotatably connected to the bearing seat 31. A pointed tip 37 is rotatably connected to the U-shaped clip 36. The pointed tip 37 and the fixing plate 33 cooperate with each other. A long rod 38 is fixed on the pointed tip 37.

[0050] The working principle and beneficial effects of the above technical solution are as follows: When the tube is being made, the electric rotating shaft 22 rotates, causing the cantilever 23 to rotate. When the cantilever 23 rotates to be close to the ground, the hydraulic cylinder 24 pushes the cantilever 23 to slide on the electric rotating shaft 22, so that the width between the cantilever 23 is consistent with the width of the steel mold shaft 26. The connecting structure 3 is manually opened to install the steel mold shaft 26. After the installation is completed, the connecting structure 3 is reset. Then the electric rotating shaft 22 reverses, causing the cantilever 23 to rotate in the opposite direction. When the extruder extrudes PE sheet strips and attaches them to the steel mold shaft 26, the electric rotating shaft 25 is started, driving the connecting structure 3 and the steel mold shaft 26 to rotate together.

[0051] When installing the steel mold shaft 26 in the connecting structure 3, rotate the pointed tip 37 to disengage it from the fixed plate 33. Then rotate the U-shaped clip 36 to release it from locking the fixed plate 33. Then rotate the fixed plate 33 to place the steel mold shaft 26 into the shaft seat 31, so that the fixed plate 33 is reset and the wedge plate 34 is nested into the wedge groove 35. Rotate the U-shaped clip 36 again to lock the fixed plate 33. Then rotate the long rod 38 to press the pointed tip 37 against the fixed plate 33 to form a fit.

[0052] This invention utilizes the rotation of the electric rotating shaft 22 and the cantilever 23. This design facilitates the installation of the steel mold shaft 26 without the need to lift it, reducing installation time and risks. Simultaneously, the hydraulic cylinder 24 pushes the cantilever 23 to slide on the electric rotating shaft 22. This design ensures that the cantilever 23 can accommodate steel mold shafts 26 of different lengths, improving the overall versatility of the equipment.

[0053] The connection between the wedge plate 34 and the wedge groove 35 of the connecting structure 3 achieves fixation. This design can reduce both the lateral displacement and the radial displacement of the steel mold shaft 26, and the structure is relatively simple. At the same time, the pointed top 37 and the U-shaped clip 36 lock the fixing plate 33. This design achieves the locking of the fixing plate 33 through self-locking, which can ensure the stability of the locking and prevent unlocking during rotation.

[0054] Example 3

[0055] Based on Embodiment 1, the unloading shaft assembly 4 includes an electric rotating shaft 41, which is rotatably connected to the frame 42. Two slewing bearing arms 43 are symmetrically mounted on the electric rotating shaft 41. Tube seats 44 are installed at both ends of the slewing bearing arms 43. Two clamps 45 are symmetrically rotatably connected inside the tube seats 44. A rotating elastic element is provided between the clamps 45 and the tube seats 44. A hydraulic telescopic rod 46 is installed inside the tube seats 44. A triangular top block 47 is connected to the hydraulic telescopic rod 46. The triangular top block 47 and the two clamps 45 are relatively slidably connected. A bearing bracket 48 is provided on one side of the frame 42.

[0056] The beneficial effects of the above technical solution are as follows: After the fiberglass composite tube is made on the steel mold shaft 26, the electric rotating shaft 41 rotates, driving the rotary bearing arm 43 to rotate. After the tube seat 44 on the rotary bearing arm 43 approaches the steel mold shaft 26, it lifts the steel mold shaft 26. Then the hydraulic telescopic rod 46 moves, pushing the triangular top block 47 to slide. The triangular top block 47 squeezes one end of the clamps 45 on both sides, causing it to rotate. The other end of the clamps 45 clamps the steel mold shaft 26. Then the rotary bearing arm 43 continues to rotate until it rotates 180°. Then the clamps 45 release the steel mold shaft 26 onto the bearing frame 48, waiting for the next fiberglass composite tube to be made.

[0057] This invention utilizes a slewing bearing arm 43 for rotation. This design ensures that the slewing bearing arm 43 can rotate periodically, automating the removal of the steel mold shaft 26, reducing labor costs, and improving work efficiency. At the same time, the cooperation between the triangular jack 47 and the clamp 45 achieves the clamping function. This design uses the triangular jack 47 to open and close the clamp 45, ensuring that the clamp 45 will not loosen the steel mold shaft 26 during the clamping process, thus avoiding safety accidents.

[0058] Example 4

[0059] Based on embodiment 1, the temporary storage component 5 includes a storage hopper 51, which is fixed on the support frame 52. Horseshoe hooks 53 are rotatably connected to both sides of the storage hopper 51. The storage hopper 51 is provided with two through slots 54. A front intercepting rod 55 and a rear intercepting rod 56 are respectively connected to both ends of the horseshoe hooks 53. The rear intercepting rod 56 is slidably connected in the through slots 54. A cam 57 is provided below each horseshoe hook 53. The cam 57 slides relative to the side of the horseshoe hook 53. The cam 57 is installed at the working end of the electric rotating shaft 58, which is rotatably connected to the support frame 52.

[0060] The beneficial effects of the above technical solution are as follows: After the PE composite tube is demolded and placed in the temporary storage component 5, the PE composite tube rolls along the storage hopper 51 until it is intercepted by the front interceptor 55 of the horseshoe hook 53. The PE composite tubes are stacked in parallel. When it is necessary to release the PE composite tube, the electric rotating shaft 58 drives the cam 57 to rotate. When the cam 57 rotates to the top, it lifts the horseshoe hook 53 and rotates it. The rotation of the horseshoe hook 53 causes the front interceptor 55 and the rear interceptor 56 to move downward. The front interceptor 55 releases the first PE composite tube, and the rear interceptor 56 slides in the through groove 54 and intercepts the subsequent PE composite tubes. The electric rotating shaft 58 continues to rotate, causing the horseshoe hook 53 to fall and reset. The rear interceptor 56 releases the PE composite tube, and the PE composite tube rolls forward until it is blocked by the front interceptor 55.

[0061] This invention utilizes the design of horseshoe hook 53, front interceptor 55, and rear interceptor 56 to retain PE composite pipes. This design ensures that after the first PE composite pipe is released, subsequent PE composite pipes are separated from the first PE composite pipe, preventing leakage from the stacked PE composite pipes. At the same time, the design of cam 57 and electric rotating shaft 58 ensures both an upward lifting effect on horseshoe hook 53 to release the PE composite pipes and a supporting and constraining effect on horseshoe hook 53, preventing it from falling and failing to constrain the stacked PE composite pipes.

[0062] Example 5

[0063] Based on Embodiment 1, the cutting assembly 6 includes a housing 61, an electric rotating shaft 62 rotatably connected inside the housing 61, a rotating wheel 63 mounted on the electric rotating shaft 62, an annular bearing groove 64 and a groove 65 on the rotating wheel 63, a PE composite pipe sliding in the annular bearing groove 64, and clamping blocks 66 symmetrically bolted in the groove 65. A compression elastic element 67 is provided between the clamping blocks 66. Limiting clips 68 are respectively installed on both sides of the rotating wheel 63, and the limiting clips 68 cooperate with the clamping blocks 66. Bushings 69 are provided on both sides of the electric rotating shaft 62, and the two bushings 69 are respectively fixed on both sides of the housing 61. A stop post 610 is installed on each of the two bushings 69, and an extrusion ring 611 is installed on the top of the stop post 610. The extrusion ring 611 slides relative to the clamping blocks 66. A material port 612 is provided on both the front and rear sides of the housing 61. Two sections 613 are symmetrically fixed on the front side of the housing 61. A cutting structure 7 is provided on the outer side of the housing 61.

[0064] The beneficial effects of the above technical solution are as follows: After the PE composite pipe passes through the feed port 612 and enters the outer shell 61, the electric rotating shaft 62 rotates, driving the rotating wheel 63 to rotate. The PE composite pipe is supported in the annular bearing groove 64 on the rotating wheel 63. When the rotating wheel 63 rotates, the clamping block 66 in the groove 65 rotates accordingly. When the clamping block 66 rotates to the stop post 610, the clamping block 66 rotates towards the PE composite pipe under the action of the extrusion ring 611. The clamping block 66 clamps the PE composite pipe and moves forward along the annular bearing groove 64. When the clamping block 66 passes the stop post 610, the clamping block 66 rotates away from the PE composite pipe under the action of the compression elastic element 67. The clamping block 66 disengages from the PE composite pipe and is finally blocked by the limiting card 68. As the rotating wheel 63 rotates, the clamping block 66 causes the PE composite pipe to move forward step by step and pass out from the feed port 612 on the outer shell 61.

[0065] This invention utilizes a rotating wheel 63 to carry and transport the PE composite pipe. This design avoids damage to the surface of the PE composite pipe during transport and allows the pipe transport length to be calculated based on the number of rotations. Meanwhile, the design of the clamping block 66 and the extrusion ring 611 enables continuous and uniform transport of the PE composite pipe, and the pressure is used to enhance the friction between the clamping block 66 and the PE composite pipe to propel the PE composite pipe forward, making it both convenient and safe.

[0066] Based on embodiment 5, the cutting structure 7 includes a sliding plate 71, which is slidably connected to the outer shell 61 via a slide rail 72. A horizontal plate 73 is fixed on the outer shell 61, and a hydraulic telescopic rod 74 is installed on the horizontal plate 73. The working end of the hydraulic telescopic rod 74 is connected to a push rod 75, which is fixed on the sliding plate 71. A hydraulic telescopic rod 76 is installed on the top of the sliding plate 71. A T-shaped rotating plate 77 and a right-angle plate 78 are rotatably connected to the side of the sliding plate 71. The longitudinal top end of the T-shaped rotating plate 77 is hinged to the working end of the hydraulic telescopic rod 76. A sliding buckle 79 is fixed to the longitudinal bottom end of the T-shaped rotating plate 77. A sliding hole 710 is provided at the transverse end of the T-shaped rotating plate 77. A sliding groove 711 is provided at the longitudinal end of the right-angle plate 78. A sliding hole 712 is provided at the transverse end of the right-angle plate 78. The sliding buckle 79 is slidably connected in the sliding groove 711. Both the sliding hole 710 and the sliding hole 712 are connected to the cutting blade component 8.

[0067] The cutting blade component 8 includes two open slides 81, which are symmetrically slidably connected to slide rail 2 82. Slide rail 2 82 is fixed to the side of slide plate 71 near the outer shell 61. Each of the two open slides 81 near slide rail 2 82 is fixed with a sliding buckle 2 83. The two sliding buckles 2 83 are slidably connected in slide hole 1 710 and slide hole 2 712 respectively. Each of the two open slides 81 is connected with a support rod 84, and each support rod 84 is provided with a cutting blade 85. The two open slides 81 and the cutting plate 613 cooperate with each other.

[0068] The beneficial effects of the above technical solution are as follows: When the PE composite pipe is cut at the cut structure 7, the hydraulic telescopic rod 74 extends and pushes the T-shaped rotating plate 77 to rotate. The rotation of the T-shaped rotating plate 77 causes the sliding buckle 79 to slide along the sliding groove 711 on the right-angle plate 78, causing the right-angle plate 78 to rotate synchronously. The rotation of the T-shaped rotating plate 77 and the right-angle plate 78 causes the sliding hole 710 and the sliding hole 712 to rotate accordingly. The sliding buckle 83 undergoes horizontal displacement within the sliding hole 710 and the sliding hole 712. This causes the sliding buckle 83 to move vertically, causing the open slide 81 to move relative to the slide rail 82. The cutting blade 85 inside the open slide 81 cuts the PE composite pipe under the relative displacement. The support rod 84 supports and fixes the cutting blade 85 to prevent relative sliding. After the PE composite pipe is cut, the hydraulic telescopic rod 76 extends and pushes the push rod 75, causing the slide rail 72 on the slide plate 71 to move relative to the outer shell 61, thereby causing the cutting blade 85 to push the cut PE composite pipe forward.

[0069] This invention utilizes the cooperation of a T-shaped rotating plate 77 and a right-angle plate 78 to drive the open slide 81. This design ensures that the relative sliding speed and distance of the open slide 81 are consistent, allowing the upper and lower cutting blades 85 to simultaneously cut the PE composite pipe. At the same time, the relative sliding between the slide plate 71 and the outer shell 61 allows the cut PE composite pipe to be pushed out while cutting it, avoiding conflict with subsequent PE composite pipes. Furthermore, the design of the sliding hole 710 and the sliding hole 712, along with the sliding buckle 83, ensures that the drive of the open slide 81 is not affected by the entry and exit of the PE composite pipe. The cooperation between the open slide 81 and the cutting plate 613 ensures that the cutting blades 85 do not collide or overlap, protecting the cutting blades 85.

[0070] Example 6

[0071] Based on Example 1, the eccentricity detection component includes a detection module, a calculation module, and an early warning module;

[0072] The detection module includes a first acquisition module, which uses multiple stress and strain sensors to detect various stress data between the electric rotating shaft 25, the cantilever 23, the connecting structure 3, and the steel mold shaft 26;

[0073] The second acquisition module is used to acquire the relative offset distance between the connecting structure 3 and the steel mold shaft 26;

[0074] The third acquisition module is used to acquire the friction coefficient between the electric rotating shaft 25, the cantilever 23, the connecting structure 3, and the steel mold shaft 26;

[0075] The fourth acquisition module is used to detect the moment of inertia of the connecting structure 3.

[0076] The computing module is used to receive, process, and calculate data from the first, second, third, and fourth acquisition modules. The computing module can also transmit the calculation results to the early warning module.

[0077] Step 1:

[0078] The calculation module calculates the eccentricity coefficient based on the relevant data collected by the first acquisition module, the second acquisition module, the third acquisition module, and the fourth acquisition module, including the electric rotating shaft 25, the cantilever 23, the connecting structure 3, and the steel mold shaft 26.

[0079]

[0080] Where: C is the rotational eccentricity coefficient of the rotating component 2, μ1 is the friction coefficient between the connecting structure 3 and the steel mold shaft 26, and J1 is the moment of inertia of the connecting structure 3 and the steel mold shaft 26 as a whole, with units of kg·m. 2 , σ i The stress at the i-th node between the connecting structure 3 and the steel mold shaft 26 detected by the first acquisition module is expressed in N / m. 2 , ε j Let L be the strain at the j-th node between the connecting structure 3 and the steel mold shaft 26 detected by the first acquisition module, L be the connection length between the connecting structure 3 and the steel mold shaft 26 in meters, ΔL1 be the relative slippage between the connecting structure 3 and the steel mold shaft 26 detected by the second acquisition module in meters, μ2 be the coefficient of friction between the electric rotating shaft 25 and the cantilever 23, and σ be the coefficient of friction between the electric rotating shaft 25 and the cantilever 23. k The stress at the k-th node between the electric shaft 25 and the cantilever 23 detected by the first acquisition module is expressed in kg·m. 2 , ε l The strain at the k-th node between the electric rotating shaft 25 and the cantilever 23 detected by the first acquisition module is m, where m is the mass of the steel mold shaft 26 in kg, r is the radius of the steel mold shaft 26 in m, and g is the gravitational acceleration in N / kg.

[0081] Step Two:

[0082] The computation module compares C and C0;

[0083] When C > C0, the early warning module is activated;

[0084] Where: C0 is the maximum permissible eccentricity coefficient.

[0085] The beneficial effects of the above technical solution are as follows: When the rotating component 2 rotates while carrying a load, due to the friction between the electric rotating shaft 25, the cantilever 23, the connecting structure 3, and the steel mold shaft 26, after a long period of operation, the rotational eccentricity between the grooved electric rotating shaft 25, the cantilever 23, the connecting structure 3, and the steel mold shaft 26 will increase due to the frictional force, eventually affecting the glass fiber composite layer wound on the steel mold shaft 26. Therefore, by calculating the eccentricity coefficient of the rotating component 2 and comparing it with the maximum eccentricity coefficient of the rotating component 2, the early warning module will issue an early warning based on the comparison result.

[0086] This invention utilizes a detection module to collect information, and a calculation module to calculate and compare the collected information to monitor the rotational eccentricity of the rotating component 2 in real time. This design can determine the working state within the rotating component 2 and prevent the production of non-standard fiberglass composite pipes when the rotating component 2 is operating with defects.

[0087] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
