[0042] The present invention provides the following embodiments

[0043] Example 1

[0044] The embodiment of the present invention provides a glass fiber composite pipe production system, such as Figure 1-11 As shown, it includes: a bottom plate 1, a rotating component 2 is provided on the bottom plate 1, the rotating component 2 is used for rotating and winding glass fiber composite materials to make pipes, an extruder is provided on one side of the rotating component 2, and a shaft unloading component 4 is provided on the other side of the rotating component 2. The shaft unloading component 4 is used to unload the completed pipes and molds, and a temporary storage component 5 is provided on the other side of the shaft unloading component 4. The temporary storage component 5 is used to store the pipes and deliver them in batches. A cutting component 6 is provided at the conveying end of the temporary storage component 5. The cutting component 6 is used to cut the edge of the glass fiber composite pipe, and also includes an eccentricity detection component. The eccentricity detection component is used to monitor the eccentricity of the rotating component 2 in real time.

[0045] The working principle and beneficial effects of the above technical solution are as follows: when making a pipe, the extruder extrude the PE sheet strip and attach it to the rotating component 2, then start the rotating component 2, and after the rotating component 2 completes the production of the pipe, the unloading shaft component 4 removes the mold on the rotating component for demoulding, and the demoulded glass fiber composite pipe is placed in the temporary storage component 5, and the temporary storage component 5 releases the glass fiber composite pipe in sequence, and enters the cutting component 6 to cut the two ends of the glass fiber composite pipe, and the eccentric detection component is used to detect the rotation of the rotating component 2 to ensure the production quality of the glass fiber composite pipe;

[0046] The present invention utilizes a rotating component 2 to produce a glass fiber composite pipe. The design can reduce the height of the cantilever 23 by rotating, thereby reducing the installation height of the mold and thus reducing the difficulty of installing the mold. No mechanical equipment is required for lifting, and manual installation can be performed with the assistance of tools. The risk during installation is reduced and the occurrence of safety accidents is avoided. The design of the shaft unloading component 4 avoids the need for manual shaft unloading and adopts semi-automatic shaft unloading to improve work efficiency. The design of the temporary storage component 5 can realize the batch delivery of pipelines, avoiding the problem that the pipelines are inconvenient to operate due to the high stacking height and the collapse of the pipe stack when the pipe is taken out. The design of the cutting component 6 ensures that the length of the core pipe remains uniform, which is convenient for unified management in the subsequent production process. At the same time, the cutting surface is flat and there is no need for secondary trimming of the pipeline. The design of the eccentricity detection component avoids the increase of the eccentricity value of the equipment due to wear after a long period of production, which ultimately leads to uneven winding of the core pipe with glass fiber.

[0047] Example 2

[0048] On the basis of Example 1, the rotating component 2 includes a frame 21, on which an electric rotating shaft 3 22 is rotatably connected, and cantilevers 23 are spline-connected at both ends of the electric rotating shaft 3 22, and a hydraulic sleeve cylinder 24 is sleeved on the electric rotating shaft 3 22, and the two ends of the hydraulic sleeve cylinder 24 are respectively connected to the cantilevers 23 at the left and right ends, and the cantilever 23 slides relative to the electric rotating shaft 3 22, and an electric rotating shaft 4 25 is installed at the other end of the cantilever 23, and a steel mold shaft 26 is installed at the working end of the electric rotating shaft 4 25 through a connecting structure 3.

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

[0050] The working principle and beneficial effects of the above technical solution are as follows: when making pipes, the electric shaft 3 22 rotates to rotate the cantilever 23. When the cantilever 23 rotates close to the ground, the hydraulic cylinder 24 pushes the cantilever 23 to slide on the electric shaft 3 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, and then the electric shaft 3 22 is reversed to make the cantilever 23 rotate in the opposite direction. When the extruder extrude the PE sheet strip and attach it to the steel mold shaft 26, the electric shaft 4 25 is started to drive the connecting structure 3 and the steel mold shaft 26 to rotate together;

[0051] When the connecting structure 3 is installed with the steel mold shaft 26, the pointed top 37 is rotated to make the pointed top 37 disengage from the fixed plate 33, and then the U-shaped card 36 is rotated to make the U-shaped card 36 release the lock on the fixed plate 33, and then the fixed plate 33 is rotated to put 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 in the wedge groove 35, and the U-shaped card 36 is rotated again to lock the fixed plate 33, and then the long rod 38 is rotated to make the pointed top 37 squeeze the fixed plate 33 to form a fit;

[0052] The present invention utilizes the electric rotating shaft 3 22 and the cantilever 23 to rotate. This design can facilitate the installation of the steel mold shaft 26. The steel mold shaft 26 can be installed without lifting it, which reduces the time and risk of the installation process. At the same time, the hydraulic sleeve cylinder 24 pushes the cantilever 23 to slide on the electric rotating shaft 3 22. This design can ensure that the cantilever 23 can adapt to steel mold shafts 26 of different lengths, thereby improving the versatility of the overall equipment.

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

[0054] Example 3

[0055] On the basis of Example 1, the unloading shaft assembly 4 includes an electric rotating shaft 5 41, which is rotatably connected to a stand 42. Two rotating bearing arms 43 are symmetrically installed on the electric rotating shaft 5 41. Both ends of the rotating bearing arms 43 are installed with pipe seats 44. Two calipers 45 are symmetrically rotatably connected in the pipe seat 44. A rotating elastic member is provided between the caliper 45 and the pipe seat 44. A hydraulic telescopic rod 46 is installed in the pipe seat 44. A triangular top block 47 is connected to the hydraulic telescopic rod 46. The triangular top block 47 and the two calipers 45 are relatively slidably connected. A bearing frame 48 is provided on one side of the stand 42.

[0056] The beneficial effects of the above technical solution are as follows: after the glass fiber composite tube is made on the steel mold shaft 26, the electric rotating shaft 5 41 rotates, driving the swivel bearing arm 43 to rotate, and after the tube seat 44 on the swivel bearing arm 43 approaches the steel mold shaft 26, the steel mold shaft 26 is lifted, and then the hydraulic telescopic rod 46 moves to push the triangular top block 47 to slide, and the triangular top block 47 squeezes one end of the caliper 45 on both sides to make it rotate, and the other end of the caliper 45 clamps the steel mold shaft 26, and then the swivel bearing arm 43 continues to rotate until it rotates 180°, and the caliper 45 releases the steel mold shaft 26 to the bearing frame 48, waiting for the next glass fiber composite tube to be made;

[0057] The present invention utilizes the swivel bearing arm 43 for rotation. This design can ensure that the swivel bearing arm 43 can realize periodic rotation, realize the automation of the removal of the steel mold shaft 26, reduce labor costs, and improve work efficiency. At the same time, the triangular top block 47 and the caliper 45 cooperate with each other to realize the clamping function. This design realizes the opening and closing of the caliper 45 through the triangular top block 47, which can ensure that the caliper 45 will not loosen the steel mold shaft 26 during the clamping process, thereby avoiding safety accidents.

[0058] Example 4

[0059] On the basis of Example 1, the temporary storage component 5 includes a storage oblique bucket 51, which is fixed on a support frame 52. Horseshoe hooks 53 are rotatably connected to the two side surfaces of the storage oblique bucket 51. Two through grooves 54 are provided on the storage oblique bucket 51. The two ends of the horseshoe hook 53 are respectively connected to a front intercepting rod 55 and a rear intercepting rod 56. The rear intercepting rod 56 is slidably connected in the through groove 54. Cams 57 are provided under the horseshoe hook 53. The cams 57 slide relative to the side surfaces of the horseshoe hook 53. The cams 57 are installed at the working end of the electric shaft 2 58, and the electric shaft 2 58 is rotatably connected to the support frame 52.

[0060] The beneficial effects of the above technical solution are as follows: after the PE composite pipe is demoulded and placed in the temporary storage component 5, the PE composite pipe rolls along the storage oblique bucket 51 until it is intercepted by the front interception rod 55 of the horseshoe hook 53, and the PE composite pipes are stacked in parallel. When the PE composite pipe needs to be released, the electric shaft 2 58 drives the cam 57 to rotate, and the cam 57 lifts up and rotates the horseshoe hook 53 when it rotates to the peak. The rotation of the horseshoe hook 53 causes the front interception rod 55 and the rear interception rod 56 to move downward, and the front interception rod 55 releases the first PE composite pipe, and the rear interception rod 56 slides in the through groove 54 and intercepts the subsequent PE composite pipes. The electric shaft 2 58 continues to rotate to cause the horseshoe hook 53 to fall and reset, and the rear interception rod 56 releases the PE composite pipe, and the PE composite pipe rolls forward until it is blocked by the front interception rod 55;

[0061] The present invention utilizes the design of the horseshoe hook 53 and the front intercepting rod 55 and the rear intercepting rod 56 to achieve the retention of the PE composite pipe. The design can ensure that after the first PE composite pipe is released, the subsequent PE composite pipes are separated from the first PE composite pipe, and the stacked PE composite pipes will not leak. At the same time, the design of the cam 57 and the electric rotating shaft 58 can ensure that the horseshoe hook 53 has an upward lifting effect to release the PE composite pipe, and can also ensure that the horseshoe hook 53 has a supporting and restraining effect to prevent the horseshoe hook 53 from falling and failing to restrain the stacked PE composite pipes.

[0062] Example 5

[0063] On the basis of Example 1, the cutting assembly 6 includes a shell 61, in which an electric rotating shaft 62 is rotatably connected, a rotating wheel 63 is installed on the electric rotating shaft 62, an annular bearing groove 64 and a groove 65 are provided on the rotating wheel 63, a PE composite pipe slides in the annular bearing groove 64, a clamping block 66 is symmetrically bolted in the groove 65, a compression elastic member 67 is provided between the clamping blocks 66, limit cards 68 are respectively installed on both sides of the rotating wheel 63, and the limit cards 68 and the clamping blocks 66 cooperate with each other, shaft sleeves 69 are provided on both sides of the electric rotating shaft 62, and the two shaft sleeves 69 are respectively fixed on both sides of the shell 61, and blocking columns 610 are installed on the two shaft sleeves 69, and an extrusion ring 611 is installed on the top of the blocking column 610, and the extrusion ring 611 and the clamping block 66 slide relative to each other, a material port 612 is provided on the front and rear sides of the shell 61, two cut plates 613 are symmetrically fixed on the upper and lower sides of the front side of the shell 61, and a truncation structure 7 is provided on the outer side of the shell 61.

[0064] The beneficial effects of the above technical solution are as follows: after the PE composite pipe passes through the material port 612 and enters the housing 61, the electric rotating shaft 1 62 rotates to drive the rotating wheel 63 to rotate, and the annular bearing groove 64 on the rotating wheel 63 carries the PE composite pipe. 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 column 610, the clamping block 66 rotates toward the PE composite pipe under the action of the extrusion ring 611, and the clamping block 66 clamps the PE composite pipe and moves forward along the annular bearing groove 64. After the clamping block 66 passes the stop column 610, the clamping block 66 rotates toward the direction away from the PE composite pipe under the action of the compression elastic member 1 67, and the clamping block 66 is out of contact with the PE composite pipe. The clamping block 66 is finally blocked by the limit card 68. As the rotating wheel 63 rotates in circles, the clamping block 66 allows the PE composite pipe to gradually move forward and pass through the material port 612 on the housing 61.

[0065] The present invention utilizes the rotating wheel 63 to realize the bearing and transportation of the PE composite pipe. This design can avoid damage to the surface of the PE composite pipe during transportation, and can calculate the pipeline transportation length according to the number of rotations. At the same time, the design of the clamping block 66 and the extrusion ring 611 can realize the continuous and uniform transportation of the PE composite pipe, and use pressure to enhance the friction between the clamping block 66 and the PE composite pipe to realize the advancement of the PE composite pipe, which is both convenient and safe.

The two open slides 81 are fixed with a second slide buckle 83 on the side close to the second slide rail 82. The two second slide buckles 83 are respectively slidably connected in the first slide hole 710 and the second slide hole 712. The two open slides 81 are connected with a load-bearing rod 84, and the load-bearing rod 84 is provided with a cutting blade 85. The two open slides 81 cooperate with the cutting plate 613.

[0068] The beneficial effects of the above technical solution are as follows: when the PE composite pipe is cut off at the cut-off structure 7, the hydraulic telescopic rod 1 74 extends to push the T-shaped rotating plate 77 to rotate, and the rotation of the T-shaped rotating plate 77 causes the sliding buckle 1 79 to slide along the sliding groove 1 711 on the right-angle plate 78, driving the right-angle plate 78 to rotate synchronously, and the rotation of the T-shaped rotating plate 77 and the right-angle plate 78 causes the sliding hole 1 710 and the sliding hole 2 712 to rotate accordingly, and the sliding buckle 2 83 is displaced horizontally in the sliding hole 1 710 and the sliding hole 2 712. , thereby causing the second slide buckle 83 to move in the vertical direction, causing the open slide 81 to move relatively on the second slide rail 82, and the cutting blade 85 in the open slide 81 cuts off the PE composite pipe under the relative displacement, and the load-bearing rod 84 carries and fixes the cutting blade 85 so that it does not slide relatively. After the PE composite pipe is cut off, the second hydraulic telescopic rod 76 extends and pushes the push rod 75, causing the first slide rail 72 on the slide 71 to move relatively with the housing 61, thereby causing the cutting blade 85 to push the cut PE composite pipe forward;

[0069] The present invention utilizes the T-shaped rotating plate 77 and the right-angle plate 78 to cooperate with each other to realize the driving of the opening slide 81. This design can ensure that the relative sliding speed and distance of the opening slide 81 are consistent, so that the upper and lower cutting blades 85 can synchronously cut the PE composite pipe. At the same time, the slide plate 71 and the shell 61 slide relatively. This design can take into account the cutting and cutting of the PE composite pipe while pushing out the cut PE composite pipe to avoid conflict with the subsequent PE composite pipe. In addition, through the design of the sliding hole 1 710, the sliding hole 2 712 and the sliding buckle 2 83, the driving of the opening slide 81 can be guaranteed without affecting the entry and exit of the PE composite pipe. The mutual cooperation between the opening slide 81 and the cutting plate 613 ensures that the cutting blades 85 will not collide with each other and overlap, thereby protecting the cutting blades 85.

[0070] Example 6

[0071] On the basis of embodiment 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 shaft 25, the cantilever 23, the connecting structure 3 and the steel mold shaft 26;

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

[0074] The third acquisition module is used to obtain the friction coefficient between the electric rotating shaft 25 and the cantilever 23 and 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 connection structure 3 .

[0076] The calculation module is used to receive, process and calculate the data of the first acquisition module, the second acquisition module, the third acquisition module and the fourth acquisition module, and the calculation module can 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 of the electric shaft 25, the cantilever 23, the connecting structure 3 and the steel mold shaft 26 collected by the first acquisition module, the second acquisition module, the third acquisition module and the fourth acquisition module:

[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 rotational inertia of the connecting structure 3 and the steel mold shaft 26 as a whole, in kg·m 2 , σ i The stress of the i-th node between the connecting structure 3 and the steel mold shaft 26 detected by the first acquisition module, in N / m 2 , ε j is the strain of the jth node between the connecting structure 3 and the steel mold shaft 26 detected by the first acquisition module, L is the connection length between the connecting structure 3 and the steel mold shaft 26, in m, ΔL1 is the relative slip between the connecting structure 3 and the steel mold shaft 26 detected by the second acquisition module, in m, μ2 is the friction coefficient between the electric rotating shaft 25 and the cantilever 23, σ k is the stress of the kth node between the electric shaft 25 and the cantilever 23 detected by the first acquisition module, in kg·m 2 , ε l is the strain of the kth node between the electric rotating shaft 25 and the cantilever 23 detected by the first acquisition module, 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 2:

[0082] The calculation module compares C and C0;

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

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

[0085] The beneficial effects of the above technical solution are as follows: when the rotating assembly 2 rotates while carrying a load, due to the friction between the electric rotating shaft 25 and the cantilever 23 and the connecting structure 3 and the steel mold shaft 26, after a long period of work, the grooved electric rotating shaft 25 and the cantilever 23 and the connecting structure 3 and the steel mold shaft 26 will cause the rotation eccentricity to become larger and larger due to the friction force, and eventually affect the glass fiber composite layer wrapped around the steel mold shaft 26. Therefore, by calculating the eccentricity coefficient of the rotating assembly 2 and comparing it with the maximum eccentricity coefficient of the rotating assembly 2, the early warning module issues an early warning according to the comparison result;

[0086] The present invention utilizes the detection module to collect information, and the calculation module calculates and compares the collected information to monitor the rotational eccentricity of the rotating component 2 in real time. This design can judge the working state of the rotating component 2 to avoid the production of non-standard glass fiber composite pipes when the rotating component 2 is working with defects.

[0087] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
