Description

Technical Field

[0001] The invention relates to the technical field of glass fiber reinforced plastic container processing, and in particular to a mobile multi-axis linkage large-diameter glass fiber reinforced plastic container production unit and a winding method. Background Art

[0002] At present, when processing and preparing extra-large FRP storage tanks, large-scale vertical winding machines in China mostly wind glass fibers attached with resin glue on storage tank containers in open areas. During the processing, the glass fibers are affected by external factors such as wind force, causing them to shake during the winding process, resulting in uneven winding of the glass fibers, resulting in uneven overall strength and poor product quality. At the same time, in the process of glass fiber winding, two methods, namely, integral production and segmented production, are often used for winding and preparation. Among them, when using the integral production method to prepare extra-large FRP storage tanks, affected by the size of the storage tank container, the winding cycle of the glass fibers is relatively long, resulting in low processing efficiency. At the same time, in this process, the resin on the glass fibers gradually solidifies after being exposed to the air for a long time, which easily causes uneven solidification of the resin glue attached to the glass fibers, resulting in uneven overall strength of the processed products. If the segmented production method is used to process and prepare extra-large FRP storage tanks, the curing strength of the product at the joint of two adjacent FRP storage tanks is relatively soft, resulting in a decrease in the integrity of the product.

[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0018] In the process of processing and preparing large-diameter FRP containers, affected by the size of the storage tank container, when the glass fiber is wrapped around the outer surface of the storage tank container to prepare the FRP container, under the influence of wind and temperature in the external environment, the glass fiber is easy to sway in the air, resulting in the glass fiber being not evenly wrapped around the storage tank container, affecting the structural strength of the finished product. At the same time, temperature changes can easily lead to uneven solidification of the resin glue, affecting the structural strength of the finished product. If the processing and preparation is carried out in a factory, it is affected by the size of the factory, resulting in difficulty in demolding the large-diameter FRP container after processing. At the same time, under the influence of the size of the storage tank container, the winding cycle in the process is long, resulting in low processing efficiency.

[0019] The invention designs a glass fiber reinforced plastic container production unit which can move and change the demoulding position and has high processing efficiency.

[0020] Example 1: A mobile multi-axis linkage large diameter glass fiber reinforced plastic container production unit, referring to Figure 1-Figure 4As shown, it includes a mobile unit 1 and three brackets 12 equidistantly distributed in the circumferential direction (the number of the three is shown in the figure, and the actual number can be set according to the actual needs), the upper part of the mobile unit 1 is equipped with a rotating shell 11 through a motor, and the bracket 12 is equipped with a lifting platform 13 through a lifting module (the lifting module is shown in the figure, which is an existing lifting mechanism). The split structure of the rotating shell 11 and the bracket 12 is used to facilitate the production and processing of glass fiber reinforced plastic containers in the factory, reduce the influence of external factors on the production of glass fiber reinforced plastic containers, and at the same time facilitate the separation of the glass fiber reinforced plastic container outside the factory, thereby improving the loading and unloading of the device. In order to improve the portability of the work, a fixed frame 17 is fixedly connected to the side wall of the lifting platform 13, and the fixed frame 17 is provided with a slide groove. Four evenly distributed sliding frames 191 are provided in the slide groove of the fixed frame 17, and the sliding frame 191 is provided with a support frame 192. The support frame 192 is rotatably provided with two symmetrical first rotating rollers 193. A limiting mechanism for squeezing glass fiber is provided on the support frame 192 to keep the glass fiber taut during the winding process. A coating mechanism for attaching resin glue to the glass fiber is provided on the fixed frame 17. The three fixed frames 17 are reciprocated at equal intervals to improve the processing efficiency of the device.

[0021] Reference Figure 2 and Figure 5 As shown, the limiting mechanism includes a first sliding frame 2, which is slidably set on an adjacent support frame 192, and two tension springs are installed between the first sliding frame 2 and the adjacent support frame 192, and the tension springs are sleeved on the adjacent first sliding frame 2. The support frame 192 is rotatably provided with two symmetrical second rotating rollers 21, and the first rotating roller 193 is provided with an annular groove, and the second rotating roller 21 is provided with a convex ring that is squeezed and matched with the groove on the adjacent first rotating roller 193. Through the cooperation of the second rotating roller 21 and the adjacent first rotating roller 193, the glass fiber remains stable during the winding process, thereby improving the uniformity of the wound glass fiber.

[0022] Reference Figure 3 , Figure 6 and Figure 7As shown, the coating mechanism includes a first fixed shell 3, the first fixed shell 3 is fixedly connected to the adjacent fixed frame 17, the first fixed shell 3 stores resin glue, the lower part of the first fixed shell 3 is connected with a first guide tube 31, the first guide tube 31 is connected to the resin glue storage tank through a pipeline, the side wall of the first fixed shell 3 is fixed with a pump body 32, the upper part of the first fixed shell 3 is embedded with a second guide tube 33, the lower end of the second guide tube 33 is connected to the upper end of the pump body 32, the lower end of the pump body 32 is connected to the resin glue storage tank through a pipeline, and two symmetrical inclined rollers 34 are rotatably arranged in the first fixed shell 3, and the two adjacent inclined rollers 34 are symmetrical to the glass passing by. The fibers are driven from top to bottom, so that the vertical glue is evenly adhered to the four adjacent glass fibers. A third rotating roller 35 is rotatably arranged on the side of the first fixed shell 3 away from the adjacent fixed frame 17. The third rotating roller 35 is used to guide the glass fibers. The amount of medium conveyed by the pump body 32 is coordinated with the positional relationship of the adjacent lifting platform 13, and the amount of resin glue is applied to the glass fibers in a step-by-step manner. By controlling the power of the pump body 32 at different heights, the amount of resin glue sprayed out by the second guide pipe 33 is compensated for the natural downward flow of the resin under the action of gravity, so that the thickness of the resin glue wrapped around the glass fibers on the rotating shell 11 remains relatively uniform.

[0023] Specific working principle: All electrical components in the present invention are electrically connected to the remote control terminal through the Internet of Things. When producing and processing fiberglass containers, the operator first controls the lifting modules on the three lifting platforms 13 through the remote control terminal, so that the three lifting platforms 13 on the three lifting platforms 13 drive the three fixed frames 17 and the parts connected thereto to move together. When the three fixed frames 17 move to the lower limit, the lifting modules on the three lifting platforms 13 are closed, and then the operator pulls the first sliding frame 2 in turn and stretches the adjacent tension springs. The first sliding frame 2 moves to drive the adjacent second rotating roller 21 away from the adjacent first rotating roller 193. Then the operator places multiple glass fibers respectively between the first rotating roller 193 and the adjacent second rotating roller 21. Then the operator releases the first sliding frame 2. Under the tension of the tension spring on the first sliding frame 2, the corresponding second rotating roller 21 moves to squeeze the adjacent glass fibers.

[0024] After all the glass fibers are installed, the operator connects the lower ends of the three pump bodies 32 through three pipes, and then connects them to the three first guide pipes 31 through three pipes, and then inserts the six pipes into the containing shell containing the resin glue to complete the preliminary preparations for the preparation of the FRP container.

[0025] After the preliminary preparations are completed, the operator sticks the head end of the glass fiber to the side wall of the rotating shell 11, and then the operator starts the motor on the mobile unit 1, the lifting modules on the three lifting platforms 13 and the three pump bodies 32 through the remote control terminal. The lifting modules on the lifting platforms 13 work to move the adjacent fixed frames 17 to the corresponding positions, and the motor on the mobile unit 1 works to control the rotating shell 11 to rotate at a uniform speed. The rotating shell 11 rotates to make the glass fiber wrap around its outer side. During this process, the pump body 32 works to transport the resin glue in the storage barrel to the second guide tube 33, and the resin glue flows out from the second guide tube 33. The resin glue that flows out adheres to the adjacent glass fibers. Then, the glass fibers attached with the resin glue are circumferentially wrapped around the side wall of the rotating shell 11 to prepare the FRP container.

[0026] In the above-mentioned glass fiber winding process, the lifting modules on the three lifting platforms 13 work under the program set by the remote control terminal. The lifting modules on the three lifting platforms 13 respectively control the adjacent fixed frames 17 to move up and down, and control the three groups of glass fibers to be annularly wound on the side wall of the rotating shell 11. This work is for the preparation of large-diameter fiberglass containers. The processing and preparation method can be based on different settings, that is, controlling different numbers of fixed frames 17 to move in different ways to complete the preparation of large-diameter fiberglass containers.

[0027] The following are some examples of processing methods. The first working method is to make the three fixed frames 17 evenly distributed in the vertical direction at equal distances, and then control the three fixed frames 17 to move synchronously at a uniform speed, so as to perform segmented synchronous winding processing on the glass fiber reinforced plastic container to avoid excessively uneven drying of the resin glue, thereby improving the curing strength and integrity of the final product.

[0028] The second working mode: when the glass fibers installed on the left and right sets of fixed frames 17 are used for winding preparation, the operator uses the program setting on the remote control terminal to control the lifting modules on the left and right lifting platforms 13 to move relative to each other, so that the two sets of glass fibers are relatively moved and wound, that is, the two sets of glass fibers are staggered and wound on the rotating shell 11. In the above-mentioned winding process of glass fibers, the movement of the fixed frame 17 drives the adjacent first fixed shell 3 and the adjacent second guide tube 33 to move together. At the same time, since the amount of resin glue delivered by the pump body 32 increases as the lifting platform 13 is higher, the subsequent resin glue is adhered to the glass fibers in large quantities, that is, the amount of resin glue adhered to the glass fibers wound on the rotating shell 11 from bottom to top gradually increases. After that, after the glass fibers are wound, the resin glue flows downward under the action of gravity, so that the resin glue is attached to the outer side of the rotating shell 11 with a relatively uniform thickness, further improving the curing strength, appearance quality and aesthetics of the prepared glass fiber reinforced plastic container.

[0029] After completing the processing of the large-diameter FRP container, the operator first closes the lifting modules and the three pump bodies 32 on the three lifting platforms 13, and then starts the mobile unit 1 to move the rotating shell 11 to the designated area to facilitate the cooling and shaping of the resin glue thereon, thereby completing the preparation of the FRP container. After the preparation is completed, the mobile unit 1 is controlled to drive the FRP container and the mobile unit 1 to move to an open environment outside the factory, and then a large crane is used for demolding to complete the preparation of the large-diameter FRP container. When preparing the large-diameter FRP container again, the operator controls the mobile unit 1 to move between the three brackets 12, and then repeats the above operations for processing and preparation.

[0030] Example 2: Based on Example 1, refer to Figure 8 As shown, it also includes three groups of swing mechanisms that are evenly distributed in an arc shape. The three groups of swing mechanisms are respectively arranged on adjacent fixed frames 17. The swing mechanisms are used to control the rotation of the corresponding support frames 192. The sliding frame 191 is rotatably connected to the adjacent support frames 192, and a torsion spring is installed between the support frame 192 and the adjacent sliding frame 191. The fixed frame 17 is provided with two horizontal slide grooves that are symmetrical up and down. The swing mechanism includes a second sliding frame 5. The second sliding frame 5 is slidably arranged in two symmetrical horizontal slide grooves on the adjacent fixed frames 17. The second sliding frame 5 is slidably arranged with four evenly distributed racks 51. The racks 51 are located in the adjacent sliding frames 191 and slide. The support frame 192 is installed with a gear. The gear on the support frame 192 is meshed with the adjacent rack 51. The fixed frame 17 is provided with a trigger component for driving the corresponding rack 51 to move. By controlling the movement of the second sliding frame 5 and the four racks 51, the inclination state of the four sliding frames 191 on the same fixed frame 17 is changed, thereby further ensuring that the glass fiber remains evenly distributed during the winding process.

[0031] Reference Figure 8 and Fig. 9As shown, the trigger assembly includes a second fixed shell 6, the second fixed shell 6 is fixedly connected to the side wall of the adjacent fixed frame 17, the fixed frame 17 is fixedly connected to the first servo motor 18, the output shaft of the first servo motor 18 penetrates the adjacent second fixed shell 6 and is rotatably connected thereto, the rotation speed of the output shaft on the first servo motor 18 is set by the control module to be the same as the moving speed of the adjacent fixed frame 17 (and the first servo motor 18 here can be replaced by a rotating shaft, a spur gear is installed on the rotating shaft, and a spur rack meshing with the spur gear is installed on the bracket 12), the side wall of the second fixed shell 6 is fixedly connected to the fixed sleeve 61, and the fixed sleeve 61 is provided with four limit grooves distributed equidistantly in the circumferential direction A first sliding shell 62 is slidably disposed in the four limiting grooves of the fixed sleeve 61, a spring is installed between the first sliding shell 62 and the adjacent second fixed shell 6, the spring is located in the adjacent fixed sleeve 61, and the first sliding shell 62 is fixedly connected to the adjacent second sliding frame 5, and the second fixed shell 6 is rotatably disposed with a first rotating shaft 63, the first rotating shaft 63 penetrates the first sliding shell 62 and is rotatably connected thereto, the first rotating shaft 63 and the output shaft of the first servo motor 18 are driven by a speed-increasing gear set, and the speed-increasing gear set is located in the adjacent second fixed shell 6, the first rotating shaft 63 is installed with two symmetrical one-way bearings 64, and a fixing ring 65 is fixedly connected to the outer side of the one-way bearing 64, so as to prevent the first rotating shaft 63 from being rotatably disposed. Fig. 9 For example, the first rotating shaft 63 rotates clockwise (from right to left) to drive the adjacent fixed ring 65 to rotate through the one-way bearing 64 on the left side thereof, and when the first rotating shaft 63 rotates counterclockwise, the first rotating shaft 63 will drive the adjacent fixed ring 65 to rotate through the one-way bearing 64 on the right side. The fixed ring 65 is provided with four sliding grooves equidistantly distributed in the circumferential direction. Sliding blocks 66 are slidably provided in the four sliding grooves of the first sliding shell 62. The four sliding blocks 66 on the same fixed ring 65 form a group, and a Spring, the outer side surfaces of the four sliding blocks 66 on the same fixed ring 65 are smooth inclined surfaces, and the inclined surfaces on the two adjacent groups of sliding blocks 66 are symmetrically distributed. The first sliding shell 62 is provided with two symmetrical frustum surfaces, and the two frustum surfaces on the first sliding shell 62 gradually increase in cross section from the two ends to the middle. The inclined surfaces of the sliding blocks 66 are squeezed and matched with the adjacent frustum surfaces on the adjacent first sliding shells 62. By rotating the first rotating shaft 63 in different directions, the first sliding shell 62 is controlled to move in different directions, thereby realizing the swinging of the sliding frame 191 in different directions.

[0032] In the process of winding the glass fiber attached with resin glue onto the rotating shell 11, the first servo motor 18 works together. At this time, the rotation speed of the first servo motor 18 is the same as the moving speed of the adjacent fixed frame 17. When the fixed frame 17 moves downward, the first servo motor 18 drives the first rotating shaft 63 to rotate through the gear set in the adjacent second fixed shell 6. Since the gear set in the second fixed shell 6 is a speed-increasing gear set, the first rotating shaft 63 rotates rapidly, and at this time, the first rotating shaft 63 rotates clockwise (with a rotation speed of 1 / 400). Figure 4 as an example and read from right to left).

[0033] The first rotating shaft 63 rotates clockwise and drives the fixed ring 65 to rotate through the one-way bearing 64 thereon close to the adjacent second fixed shell 6, but the first rotating shaft 63 cannot drive the fixed ring 65 to rotate continuously through another one-way bearing 64 thereon, wherein the high-speed rotating fixed ring 65 drives the adjacent sliding block 66 to move and rotate, and the sliding block 66 is protruded from the corresponding fixed ring 65 by the centrifugal action and compresses the connected spring, and the protruding sliding block 66 contacts and squeezes the adjacent first sliding shell 62, and the first sliding shell 62 is squeezed and moves close to the adjacent second fixed shell 6 and compresses the connected spring.

[0034] The first sliding shell 62 moves through the adjacent second sliding frame 5 to drive the adjacent four racks 51 to move, and the racks 51 move through the adjacent gears to make the adjacent support frames 192 swing, maintaining the inclination angle of the four support frames 192 on the same fixed frame 17, so that the glass fibers clamped on the four support frames 192 all maintain a consistent inclination angle, ensuring that the four glass fibers are wound around the outside of the rotating shell 11 with the same tightness, further improving the overall strength and strength uniformity of the processed products.

[0035] When the fixed frame 17 approaches the reversing area, the moving speed of the fixed frame 17 gradually slows down, that is, the rotation speed of the output shaft on the first servo motor 18 gradually slows down, that is, the rotation speed of the first rotating shaft 63 also gradually slows down, wherein the protrusion amount of the sliding block 66 on the corresponding fixed ring 65 under the centrifugal action becomes less, and under the elastic force of the spring on the corresponding first sliding shell 62, the first sliding shell 62 gradually moves in the opposite direction to reset, that is, the corresponding four support frames 192 gradually swing in the opposite direction to reset, thereby ensuring that the glass fiber is always wound around the rotating shell 11 with a relatively uniform tension.

[0036] After the fixed frame 17 moves to the lower limit position, the fixed frame 17 moves upward, and at the same time, the output shaft on the first servo motor 18 rotates in the opposite direction, so that the fixed frame 17 repeats the above operation, wherein the first rotating shaft 63 rotates in the opposite direction to rotate the fixed ring 65 away from the adjacent second fixed shell 6, and the fixed ring 65 rotates to make its inner sliding block 66 extend out and squeeze the adjacent first sliding shell 62 to perform the above-mentioned opposite movement, and the first sliding shell 62 drives the four racks 51 to move through the adjacent second sliding frame 5, so that the four support frames 192 swing in the above-mentioned opposite direction.

[0037] During the above-mentioned glass fiber winding process, the inclination of the glass fiber makes it easier for the glass fiber to be always wound around the rotating shell 11 with appropriate tension, thereby improving the overall strength of the prepared glass fiber reinforced plastic container.

[0038] Example 3: Based on Example 2, refer to Figure 8 and Fig.10 As shown, it also includes a spacing adjustment mechanism, which is arranged on adjacent fixed frames 17. The spacing adjustment mechanism is used to adjust the distance between two adjacent support frames 192 on the same fixed frame 17. The sliding frame 191 is located in the slide groove of the adjacent fixed frame 17 and slides. The spacing adjustment mechanism includes a second servo motor 7, which is fixedly connected to the adjacent fixed frame 17 through a connecting seat. The fixed frame 17 is rotatably provided with a spline shaft 71, and the spline shaft 71 is rotatably connected to the uppermost sliding frame 191 on the adjacent fixed frame 17. The remaining sliding frames 191 on the same fixed frame 17 except the lowermost one are all fixedly connected with a fixed frame 72. The fixed frame 72 is limitedly rotatably provided with a threaded rod 73, and the threaded rod 73 is slidably matched with the adjacent spline shaft 71, and the threaded rod 73 is threadedly matched with the adjacent sliding frame 191. The spacing between the four sliding frames 191 on the same fixed frame 17 is adjusted by the rotation of the second servo motor 7 to control the winding density of the glass fiber on the rotating shell 11.

[0039] During the process of processing and preparing large-diameter FRP containers, the operator calculates the optimal number of tangent points for winding according to the diameter and height of the processed FRP containers. Subsequently, the operator adjusts the moving speed of the lifting module on the bracket 12 on the remote control terminal according to the optimal number of tangent points, that is, adjusts the moving speed of the fixed frame 17. At the same time, the remote control terminal starts the second servo motor 7. The second servo motor 7 drives the adjacent spline shaft 71 to rotate. The rotation of the spline shaft 71 drives the three adjacent threaded rods 73 to rotate. The rotation of the threaded rod 73 causes the adjacent sliding frames 191 to move. At the same time, under the limiting action of the three fixed frames 72, it is ensured that the distance between the threaded rod 73 and the upper sliding frame 191 is always kept constant. At this time, the spacing between the four sliding frames 191 on the same fixed frame 17 is synchronously enlarged, that is, the spacing between the four clamped glass fiber diameters on the fixed frame 17 changes, which is convenient for starting the number of winding circles of the glass fiber on the rotating shell 11 and the spacing between the glass fibers, thereby improving the product quality of the processed FRP container, high curing strength, strong integrity, uniform linear shape and beautiful appearance.

[0040] Example 4: Based on Example 3, refer to Figure 3 , Fig.11 and Fig.12 As shown, it also includes multiple groups of friction mechanisms, which are respectively arranged on adjacent support frames 192. The friction mechanisms are used to control the adjacent glass fibers to remain taut. The friction mechanisms include a third fixed shell 8, which is fixed to the lower surface of the adjacent support frame 192. The third fixed shell 8 is slidably provided with a second sliding shell 81. The lower part of the support frame 192 is slidably provided with a limited position ratchet 82. Two symmetrical springs are installed between the limited position ratchet 82 and the adjacent support frame 192. The springs are sleeved on the adjacent limited position ratchet 82. The second sliding shell 81 is provided with a limited position block. The limited position block of the second sliding shell 81 is limitedly matched with the adjacent limited position ratchet 82. The second sliding shell 81 is slidably provided with a third sliding frame 83. A spring is installed between the moving frame 83 and the adjacent second sliding shell 81, and the spring is sleeved on the adjacent third sliding frame 83. In the initial state, the spring between the third sliding frame 83 and the adjacent second sliding shell 81 is in a force storage state. The first rotating roller 193 on the support frame 192 close to the third sliding frame 83 is fixedly connected to the second rotating shaft 84. The second rotating shaft 84 is provided with a friction wheel that frictionally cooperates with the adjacent third sliding frame 83. The support frame 192 is provided with a compensation component for compensating for the amount of wear. Through the friction cooperation between the third sliding frame 83 and the friction wheel on the adjacent second rotating shaft 84, the tension of the glass fiber during the winding process is kept stable, thereby further ensuring that the glass fiber is evenly wound on the rotating shell 11, thereby improving the overall strength of the finished product.

[0041] Reference Fig.11 and Fig.12As shown, the compensation component includes a third rotating shaft 9, which is rotatably arranged on a support frame 192, an L-shaped rod is arranged on the upper part of the third rotating shaft 9, and a fourth fixed shell 91 is fixedly connected to the lower surface of the support frame 192, a sliding plug 92 is slidably arranged in the fourth fixed shell 91, the sliding plug 92 is provided with a sliding groove that slides with the L-shaped rod on the adjacent third rotating shaft 9, the sliding plug 92 is provided with four through holes that are equidistantly distributed in the circumferential direction and are all equipped with a one-way valve, the one-way valve on the sliding plug 92 is used for external gas to enter it and the adjacent fourth fixed shell 91, the second sliding shell 81 and the adjacent fourth fixed shell 91 are fixedly connected and communicated with a conduit 93, a one-way valve for the gas in the adjacent fourth fixed shell 91 to be discharged through it is installed in the conduit 93, and the A sliding column 94 is slidably arranged in the second sliding shell 81, and the sliding column 94 is fixedly connected to the adjacent third sliding frame 83. The sliding column 94 penetrates the adjacent second sliding shell 81 and is slidably connected thereto. The sliding column 94 is provided with an L-shaped hole. The L-shaped hole of the sliding column 94 is used for connecting the chamber between the adjacent third fixed shell 8 and the adjacent second sliding shell 81 with the adjacent conduit 93. The third rotating shaft 9 and the adjacent second rotating shaft 84 are driven by a sprocket and a chain. Through the cooperation between the conduit 93 and the L-shaped hole of the adjacent sliding column 94, combined with the reciprocating movement of the sliding plug 92, the second sliding shell 81 moves to compress the spring between it and the adjacent third sliding frame 83, thereby ensuring the relative stability of the friction force between the third sliding frame 83 and the friction wheel on the adjacent second rotating shaft 84.

[0042] When performing the above-mentioned glass fiber winding operation, the glass fiber is wound around the first rotating roller 193 connected to the second rotating shaft 84 for two weeks, and in the initial state, the spring on the third sliding frame 83 is in a compressed state, and then the third sliding frame 83 is squeezed by the elastic force of the spring on the third sliding frame 83, and the third sliding frame 83 is squeezed and pressed against the friction wheel of the second rotating shaft 84. In the process of the glass fiber being wound around the rotating shell 11, the glass fiber is hindered by the friction force between the third sliding frame 83 and the friction wheel on the second rotating shaft 84, and the glass fiber remains taut, so that the glass fiber is further wound around the rotating shell 11 with a constant tension, thereby improving the overall strength of the prepared glass fiber reinforced plastic container.

[0043] As the glass fiber is continuously wound around the rotating shell 11, the third sliding frame 83 and the friction wheel on the adjacent second rotating shaft 84 are rubbed for a long time, wherein the third sliding frame 83 and the friction wheel on the adjacent second rotating shaft 84 are worn to varying degrees. At this time, under the elastic force of the spring on the third sliding frame 83, the third sliding frame 83 moves to be close to the friction wheel on the adjacent second rotating shaft 84, that is, the spring on the third sliding frame 83 is gradually released and its elastic force gradually decreases, and the movement of the third sliding frame 83 simultaneously drives the adjacent sliding column 94 to move, and the sliding column 94 moves. The L-shaped hole on it is connected to the adjacent conduit 93. When the first rotating roller 193 rotates to drive the adjacent second rotating shaft 84 to rotate, the second rotating shaft 84 drives the adjacent third rotating shaft 9 to rotate through the sprocket and the chain. The rotation of the third rotating shaft 9 squeezes the adjacent sliding plug 92 through the L-shaped rod on it to reciprocate left and right. The sliding plug 92 reciprocates left and right to squeeze the gas in the adjacent fourth fixed shell 91 through the adjacent conduit 93 and the L-shaped hole of the adjacent sliding column 94 into the chamber between the adjacent third fixed shell 8 and the adjacent second sliding shell 81.

[0044] Under the action of the one-way valve in the conduit 93, the gas continuously enters the chamber between the third fixed shell 8 and the adjacent second sliding shell 81 to increase the internal pressure. Under the driving action of the high-pressure gas, the second sliding shell 81 gradually extends out from the adjacent third fixed shell 8. The movement of the second sliding shell 81 causes its upper limit block to squeeze the adjacent limit ratchet 82 to move at the same time. The limit ratchet 82 moves and compresses the connected spring, and the second sliding shell 81 moves to re-compress the spring between it and the adjacent third sliding frame 83. When the elastic force of the spring between the second sliding shell 81 and the adjacent third sliding frame 83 recovers to the set value, the L-shaped hole on the sliding column 94 is staggered with the adjacent conduit 93 again, and the upper limit block of the second sliding shell 81 moves to the next limit area of ​​the adjacent limit ratchet 82. The subsequent sliding plug 92 reciprocates to compress the gas in the adjacent fourth fixed shell 91. When the friction wheels on the third sliding frame 83 and the adjacent second rotating shaft 84 are severely worn again, the above operation is repeated to always maintain the tightness of the glass fiber during the winding process.

[0045] After long-term use, when the wear degree of the friction wheels on the third sliding frame 83 and the adjacent second rotating shaft 84 affects the stability of their tension, the operator only needs to replace the friction wheels on the third sliding frame 83 and the adjacent second rotating shaft 84 in time.

The motor on the mobile unit 1 drives the rotating shell 11 to rotate, and the lifting modules on all the lifting platforms 13 work to control the fixed frame 17 to reciprocate in an indirect distributed manner, so that the glass fiber fixed thereon is continuously wound on the rotating shell 11 in a zone-by-zone manner, and at the same time, all the pump bodies 32 work to make the resin glue evenly adhere to the glass fiber; S4: During the movement of the fixed frame 17, the first servo motor 18 drives the first rotating shaft 63 to rotate through the connected parts, the first rotating shaft 63 moves the rack 51 through the connected parts, the rack 51 moves through the connected parts to make the support frame 192 swing, and the swing of the support frame 192 changes the inclined winding of the glass fiber onto the rotating shell 11; S5: During the above-mentioned glass fiber winding process, the third sliding frame 83 and the adjacent second rotating shaft 84 continue to rub against each other, and at the same time, the second rotating shaft 84 causes the sliding plug 92 to reciprocate and adjust the position of the second sliding shell 81 through the connected parts; S6: After the glass fiber is gradually wound on the rotating shell 11 to complete the initial processing of the large-diameter FRP container, turn off the motor on the mobile unit 1, all the lifting modules on the lifting platform 13, all the first servo motors 18 and all the pump bodies 32, and then control the mobile unit 1 to move to the corresponding position, waiting for the resin glue in the glass fiber wound on the rotating shell 11 to solidify. After the resin glue is solidified, control the mobile unit 1 to move outside the factory, and then use the existing traction equipment to demold the glass fiber on the rotating shell 11 to complete the processing and preparation of the large-diameter FRP container, and repeat the above operations for subsequent processing.
