[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0032] Embodiment

[0033] Refer to Figures 1-7 As shown in the figure, the present utility model provides a technical solution: an adjustable pressure roller mechanism for forming a glass fiber reinforced plastic sand-filled pipe, including a column 1 and an adjustment mechanism 3. A base 2 is installed on the column 1. The adjustment mechanism 3 includes a positioning plate 31, which is fixedly installed on the outside of the column 1. A connecting seat 311 is slidably installed at the inner side position of the positioning plate 31. An extrusion roller 32 is rotatably installed on the connecting seat 311. A disc 321 is installed at the outer end of the extrusion roller 32. A servo motor 33 is fixedly installed on the outer surface of the column 1. A lead screw 331 is fixedly installed at the output end of the servo motor 33. A connecting block 332 is installed on the outside of the lead screw 331. The connecting block 332 is fixedly connected to the connecting seat 311.

[0034] In a preferred embodiment, an electric telescopic rod 4 is provided on the outside of the positioning plate 31. The telescopic end of the electric telescopic rod 4 is rotatably connected to a push rod 5. The push rod 5 is fixedly connected to the disc 321. The device actively controls the rotation of the extrusion roller 32 to realize the extrusion of the glass fiber so that it tightly wraps around the mold. For the convenience of operation, a push rod 5 is installed on the disc 321. The push rod 5 is rotatably connected to the telescopic end of the electric telescopic rod 4.

[0035] In a preferred embodiment, through holes 6 are provided on the outer surface of the positioning plate 31, and sliding grooves 7 are provided on the inner walls of the through holes 6. A moving block 8 is provided inside the sliding grooves 7. The moving block 8 is fixedly connected to the connecting seat 311. The electric telescopic rod 4 is rotatably installed on the outer surface of the moving block 8. Since the thickness of the glass fiber wrapped around the mold continuously increases, to enable the extrusion roller 32 to continue to limit and extrude the glass, the moving block 8 is fixedly connected to the connecting seat 311. By controlling the movement of the moving block 8, the position of the extrusion roller 32 can be adjusted to meet the use requirements.

[0036] In a preferred embodiment, the screw rod 331 is threadedly connected to the nut, and the connecting block 332 is fixedly installed on the outside of the nut. The interior of the connecting block 332 is set to be hollow, and one end of the screw rod 331 is set inside the connecting block 332. The device can automatically adjust the position of the extrusion roller 32. By installing the connecting block 332 on the outside of the screw rod 331, the servo motor 33 controls the rotation of the screw rod 331, thereby controlling the movement of the connecting block 332, and thus moving the connecting seat 311, the position of the extrusion roller 32 can be adjusted, and it changes as the thickness of the glass fiber winding increases.

[0037] In order to improve the extrusion effect of the glass fiber, two extrusion rollers 32 are provided and are both installed at a position on one side of the outer side of the column 1. A wear-resistant sleeve is installed on the outer surface of each extrusion roller 32. A piston cylinder 9 is installed on the outside of the positioning plate 31. A support rod 10 and a piston 11 are slidably installed inside the piston cylinder 9. The support rod 10 is fixedly connected to the piston 11. When the extrusion roller 32 rolls and extrude with the glass fiber, heat is generated due to friction. In order to reduce the heat of the extrusion roller 32, an air inlet pipe 12 and an air outlet pipe 13 are provided on the outer surface of the piston cylinder 9. The position of the air outlet pipe 13 corresponds to the position of the extrusion roller 32. A one-way valve is respectively provided on the air inlet pipe 12 and the air outlet pipe 13. The rotation of the push rod 5 is controlled by the telescopic end of the electric telescopic rod 4, thereby driving the rotation of the disc 321. While controlling the rotation of the push rod 5, the support rod 10 is squeezed, so that the support rod 10 pushes the piston 11, squeezes the gas inside the piston cylinder 9, and blows air to the extrusion roller 32, so as to reduce the temperature of the extrusion roller 32 itself, which is convenient for use.

[0038] This device is provided with a spring on the outside of the support rod 10. When the push rod 5 is misaligned with the support rod 10, the push rod 5 will be ejected under the action of the spring, and the outside air will be sucked into the interior of the piston cylinder 9 so that the squeezing roller 32 can continue to be blown to cool the squeezing roller 32.

[0039] Since the glass fiber is wound on the mold and moves from one end to the other, the extrusion roller 32 also needs to move accordingly. A base plate 14 is provided at the bottom of the base 2, and a moving mechanism 15 is provided on the base plate 14. The moving mechanism 15 includes a control motor 151, a pressure sensor 152 and a driving wheel 153. A moving groove 16 is provided on the upper surface of the base plate 14, and a base 2 is provided inside the moving groove 16. A pressure sensor 152 is fixedly installed on the inner wall of the moving groove 16. The pressure sensor 152 is electrically connected to the PLC controller 17, and the PLC controller 17 is electrically connected to the servo motor 33. The control motor 151 is fixedly installed on the base 2, and the drive wheel 153 is installed at the output end of the control motor 151. The drive wheel 153 is engaged with the base plate 14.

[0040] During actual use, the driving wheel 153 is controlled to rotate by controlling the motor 151. The driving wheel 153 is meshed and connected with the bottom plate 14, which will control the slow movement of the base 2, thereby driving the extrusion roller 32 to move, and it will change with the change of the winding position. The extrusion roller 32 always extrudes the fiberglass.

[0041] Specifically, the working process or principle of an adjustable pressure roller mechanism for the forming of a glass fiber reinforced plastic sand-filled pipe is as follows: In the production of a glass fiber reinforced plastic sand-filled pipe, glass fiber is mixed with resin, and the glass fiber is wound around a mold pipe. By continuously winding the resin-coated glass fiber around the mold pipe, in order to make the glass fiber tightly wound around the mold pipe, a pressure roller is arranged outside the mold. The glass fiber is extruded by the pressure roller so that the glass fiber can be tightly wound around the mold pipe. However, in actual operation, as the thickness of the glass fiber wound around the mold pipe continuously increases, and the pressure roller is fixed, this will affect the winding of the glass fiber and the processing and use. Therefore, this device is designed to solve this problem.

[0042] With this device, the position of the extrusion roller 32 can be conveniently adjusted, so that the extrusion roller 32 can extrude the fiberglass throughout the process, and the fiberglass is tightly wound around the mold, improving the production effect of the product. The specific operation is as follows: Connect to an external power supply, install this device at a position on one side of an external mold, mix the fiberglass and resin together. At this time, the outer surface of the fiberglass will be coated with resin, and then the fiberglass is wound around the mold. In order to make the fiberglass tightly wound around the mold, the extrusion roller 32 is used to extrude it to prevent it from loosening and affecting the manufacture of the product.

[0043] While the fiberglass is being wound around the mold, the extrusion roller 32 is pressed against the fiberglass. To improve the use effect, this device drives the push rod 5 to rotate through the telescopic movement of the telescopic end of the electric telescopic rod 4, and the push rod 5 is fixedly connected to the disc 321, thereby driving the disc 321 to rotate, which will drive the extrusion roller 32 to rotate. Through the continuous rotation of the extrusion roller 32, the fiberglass is extruded by the extrusion roller 32. This method replaces the passive rotation method of the extrusion roller 32, improves the extrusion effect on the fiberglass, tightly winds the fiberglass around the mold, and meets the use requirements.

[0044] When the fiberglass is wound around the mold, it will move from one end of the mold to the other end. The fiberglass is always extruded by the extrusion roller 32 during the winding process. When the winding position moves, this device will control the driving wheel 153 to rotate by controlling the motor 151. The driving wheel 153 is meshed and connected with the bottom plate 14, which will control the slow movement of the base 2, thereby driving the extrusion roller 32 to move, and it will change with the change of the winding position. The extrusion roller 32 always extrudes the fiberglass.

[0045] When the glass fiber is wound from one end around the other end, the base 2 will also move to a position at one end inside the moving groove 16. By squeezing the pressure sensor 152 through the base 2, when the pressure sensor 152 detects the existence of pressure, it will control the servo motor 33 to work through the PLC controller 17. By driving the screw rod 331 to rotate through the servo motor 33, it will control the connecting block 332 to move and the connecting seat 311 to move, so as to change the position of the extrusion roller 32, in order to extrude glass fibers of different thicknesses and improve the extrusion effect on the glass fibers. Then, the control motor 151 will control the driving wheel 153 to rotate, so as to control the extrusion roller 32 to move back and continue to extrude it.

[0046] It should be noted that the servo motor 33, the electric telescopic rod 4, the control motor 151, the pressure sensor 152 and the PLC controller 17 are devices or equipment existing in the prior art, or devices or equipment that can be realized by the prior art. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail here.
