Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic winding machines, and more specifically to a winding device with a limiting structure for glass fiber reinforced plastic production. Background Art

[0002] FRP is a fiber-reinforced plastic, which is usually wrapped around the outer protective layer of the insulated pipe in the form of fibers. Taking advantage of its light weight, high strength and corrosion resistance, it can effectively protect the outside of the pipe. In order to quickly and effectively wrap the FRP fiber around the outer layer of the pipe, workers usually use a FRP fiber winding machine to wrap the pipe.

[0003] However, the patents under the existing technology have the following disadvantages:

[0004] (1) The existing utility model winding device for FRP production is not provided with a structure that can limit the left and right moving distance of the movable frame. In order to improve the application range of the winding device for FRP production, the FRP winding device is required to be able to wind winding tubes of different lengths. This causes the movable frame to change the distance of moving the fiber line left and right. The required moving distance of the movable frame is limited to prevent the fiber line from exceeding the winding length and causing waste. However, the existing FRP production winding device lacks a limiting structure, and it is necessary to manually determine the left and right reciprocating points of the movable frame and manually adjust the steering of the motor, which results in large errors and consumes manpower.

[0005] (2) The existing utility model winding device for FRP production does not have a structure that can adjust the spacing between fiber lines. In order to improve the scope of application of the winding device for FRP production, it is necessary for the winding device for FRP production to be able to wind winding tubes of different diameters. Due to the different diameters of FRP tubes, the winding spacing between the fiber lines needs to be adjusted, otherwise it will affect the structural strength of the FRP tube. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0042] Example 1:

[0043] like Figures 1 to 7 As shown, a winding device for glass fiber reinforced plastic production with a limiting structure includes: a fixed base plate 1, a fiber line displacement driving component 2, a movable frame displacement limiting component 3, a fiber line spacing adjustment component 4 and a winding tube clamping and rotating driving component 5; the fiber line displacement driving component 2 is arranged at the top of the fixed base plate 1; the movable frame displacement limiting component 3 is arranged between two support rods 201; the fiber line spacing adjustment component 4 is arranged at the bottom of the movable frame 206; the winding tube clamping and rotating driving component 5 is arranged at the top of the fixed base plate 1.

[0044] The winding tube clamping and rotating drive assembly 5 includes: a support platform 501, a screw rod 2 502, a support rod 2 503, a motor 3 504, a rotating shaft 506, a fixed wheel 509, a winding tube 510, a rotating disk 511 and a bevel gear 6 513. The support platform 501 is fixedly connected to the top of the fixed base plate 1, and a slide groove is provided on both sides of the top of the support platform 501. The screw rod 2 502 is rotatably connected to the inner side of the support platform 501. The thread directions of the two ends of the screw rod 2 502 are opposite. The support rod 2 503 has two and is respectively threadedly connected to the outer sides of the two ends of the screw rod 2 502. The support rod 2 503 is slidably connected to the slide groove at the top of the support platform 501. The motor 3 504 is fixedly installed on the right side of the right support rod 2 503. A dust cover is fixedly installed on the outside of the motor 3 504. The top of the driving shaft of the motor 3 504 is fixedly connected to the bevel gear 3 505. The rotating shaft 506 is rotatably connected to the inner side of the top of the right support rod 2 503. 06 is fixedly connected to a bevel gear four 507 at one end, and the bevel gear four 507 is meshed with the bevel gear three 505. The other end of the rotating shaft 506 is fixedly connected to a driving wheel 508, and a protrusion for positioning is provided on the outside of the driving wheel 508. The fixed wheel 509 is fixedly connected to the right side of the left support rod two 503. The fixed wheel 509 is a standard circle. The winding tube 510 is arranged between the support rods 503. One end of the winding tube 510 has a connecting tube one adapted to the fixed wheel 509 and rotatably connected to it, and the other end of the winding tube 510 has a connecting tube two adapted to the driving wheel 508. There is a groove for positioning in the connecting tube two. The rotating disk 511 is arranged on the front side of the support platform 501. One side of the rotating disk 511 is fixedly connected to a bevel gear five 512. The bevel gear five 512 is rotatably connected to the support platform 501. The bevel gear six 513 is arranged on the outside of the screw rod two 502, and the bevel gear six 513 is meshed with the bevel gear five 512.

[0045] The utility model has multiple winding tubes 510 that can be used interchangeably, and each winding tube 510 has differences only in the length and diameter of the tube body. The structural design of the two ends remains unchanged, which is convenient for winding glass fiber reinforced plastic tubes of different lengths and diameters.

[0046] One worker docks the connecting pipe 2 with a positioning groove at one end of the winding pipe 510 with the driving wheel 508, and another worker holds the rotating disk 511 and rotates it, causing the bevel gear 512 to drive the bevel gear 6 513 to rotate, thereby driving the screw rod 2 502 to rotate. Since the thread directions at both ends of the screw rod 2 502 are opposite, the support rods 2 503 on the left and right sides are close to each other, so that the driving wheel 508 and the fixed wheel 509 are tightly stuck in the connecting pipe 2 and the connecting pipe 1 respectively, completing the installation of the winding pipe 510.

[0047] The fiber line spacing adjustment component 4 includes: motor 2 401, support frame 1 404, support frame 2 405, fixed shaft 407, rotating rod 2 408 and rotating rod 3 409, motor 2 401 is fixedly installed at the bottom end of the mobile frame 206, the outer side of the driving shaft at the top of motor 2 401 is fixedly connected with rotating rod 1 402, a slide rail 403 is provided on the inner side of the bottom of the mobile frame 206, support frame 1 404 is located on the inner side of the slide rail 403, the bottom of support frame 1 404 is inserted by the driving shaft of motor 2 401 and the two are rotatably connected, support frame 2 405 is arranged on both sides of support frame 1 404, support frame 2 405 is slidably connected to the slide rail 403, the tops of support frame 1 404 and support frame 2 405 are fixedly connected with a threading tube 406, fixed shaft 4 07 is fixedly connected to the top of the support frame 2 405, and the outer side of the fixed shaft 407 is fixedly connected to the limiting ring. The middle section of the rotating rod 2 408 is rotatably connected to the outer side of the fixed shaft 407 close to both sides of the support frame 1 404. The rotating rod 2 408 is restricted by the limiting ring and cannot slide up and down. The rotating rod 2 408 is equal to the rotating rod 1 402 in length, and one end of the two rotating rods 2 408 is rotatably connected to one end of the rotating rod 1 402 respectively. One end of the rotating rod three 409 is rotatably connected to the outer side of the fixed shaft 407 away from both sides of the support frame 1 404. The rotating rod three 409 is restricted by the limiting ring and cannot slide up and down. The length of the rotating rod three 409 is half of the rotating rod two 408, and the other end of the rotating rod three 409 is rotatably connected to the other end of the rotating rod two 408.

[0048] For winding tubes 510 of different diameters, the spacing between the fiber lines is different. It is necessary to adjust the spacing between the fiber lines so that the resin can be applied for penetration and the structural strength of the FRP tube can be improved.

[0049] Starting motor 2 401 causes its drive shaft to rotate at a low speed, and the drive shaft drives rotating rod 1 402 to rotate. Since the bottom of support frame 1 404 is inserted by the drive shaft and is rotatably connected to it, support frame 1 404 will not be displaced in slide rail 403. Support frame 2 405 is restricted by slide rail 403 and can only slide in a straight line. Rotating rod 1 402 rotates, driving rotating rod 2 408 to rotate. Rotating rod 2 408 drives support frames 2 405 near both sides of support frame 1 404 to move closer to or away from support frame 1 404 in slide rail 403. Similarly, rotating rod 2 408 rotates, driving rotating rod 3 409 to rotate. Rotating rod 3 409 drives The support frames 2 405 on both sides of the support frame 1 404 move relatively close to or away from the support frame 1 404 in the slide rail 403. Since the lengths of the rotating rod 1 402 and the rotating rod 2 408 are relatively large, the rotating rod 3 409 is half of the rotating rod 2 408, so that the distance of movement between the support frame 1 404 and the support frame 2 405 and between different support frames 2 405 each time is the same, thereby completing the equidistant adjustment of the threading tube 406. After the adjustment is completed, stop the motor 2 401 and lock its drive shaft, pass the fiber lines on the line rack through the threading tubes 406 respectively, and fix the ends of the fiber lines on the winding tube 510 to complete the installation of the fiber lines.

[0050] The fiber line displacement drive assembly 2 includes: a support rod 201, a screw rod 202, a bevel gear 203, a motor 204, a bevel gear 205 and a movable frame 206; there are two support rods 201 and both are fixedly connected to the two sides of the top of the fixed base plate 1, the screw rod 202 is rotatably connected between the two support rods 201, the bevel gear 203 is fixedly connected to one end of the screw rod 202, the motor 204 is fixedly installed on the right side of the right support rod 201, a dust cover is fixedly installed on the outside of the motor 204, the bevel gear 205 is fixedly connected to the top of the drive shaft at the top of the motor 204, the bevel gear 205 is meshed with the bevel gear 203, and the movable frame 206 is threadedly connected to the outside of the screw rod 202.

[0051] The movable frame displacement limit assembly 3 includes: a limit tube 301, a pressure sensor 302, a limit shaft 303, an extrusion plate 305 and a spring 306. The limit tube 301 is fixedly connected between the two support rods 201, the movable frame 206 is slidably connected to the limit tube 301, and a limit groove 304 is provided on the outer sides of both ends of the limit tube 301. The pressure sensor 302 is fixedly installed on both ends of the limit tube 301, the limit shaft 303 is fixedly connected between the two pressure sensors 302, the extrusion plate 305 is slidably connected to the outer side of the limit tube 301, and the extrusion plate 305 is slidably connected to the limit shaft 303 and the limit groove 304 respectively. The spring 306 is sleeved on the outer side of the limit shaft 303 and fixedly connected between the extrusion plate 305 and the pressure sensor 302.

[0052] After completing the installation of the winding tube 510 and the fiber line, start the motor three 504 so that its drive shaft drives the bevel gear three 505 to rotate, and the bevel gear three 505 drives the bevel gear four 507 to rotate the rotating shaft 506 and the driving wheel 508, thereby driving the winding tube 510 to rotate and winding the fiber line around the outside of the winding tube 510. Since the wire rack where the fiber line is stored has a tension adjustment structure, the tightness of the fiber line winding can be well controlled.

[0053] Starting motor 1 204 causes its drive shaft to rotate bevel gear 2 205, and bevel gear 205 drives bevel gear 1 203 to rotate, so that screw 1 202 drives the movable frame 206 restricted by the limiting tube 301 to slide outside the limiting tube 301, so that the fiber line can be evenly wound on the outside of the winding tube 510.

[0054] The pressure value of the pressure sensor 302 can be input and adjusted according to the length of the winding tube 510. When the movable frame 206 slides on the outside of the limiting tube 301 and slides to one end, the movable frame 206 gradually pushes the extrusion plate 305, so that the extrusion plate 305 squeezes the spring 306, and the spring 306 transmits the pressure to the pressure sensor 302. When the pressure sensor 302 in one end of the limiting tube 301 monitors the target pressure value, the pressure sensor 302 will control the motor 1 204 to rotate in the opposite direction, so that the movable frame 206 slides toward the other end of the limiting tube 301. This is repeated to limit the movable frame 206, so that the fiber line can be wound more evenly. When the fiber line is wound, resin can be applied to the outside of the winding tube 510 to improve the structural strength of the glass fiber reinforced plastic pipe, and finally complete the winding of the glass fiber reinforced plastic.

[0056] The pressure sensor and the wire rack with a tension adjustment structure used for the fiber line are both existing products on the market. Their connection methods and control methods are all existing technologies and will not be described in detail here.

[0057] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
