Description

Technical Field

[0001] This invention relates to the field of non-metallic composite pipe processing technology, and in particular to an automatic adhesive control device for manufacturing fiberglass pipes. Background Technology

[0002] Fiber winding is one of the manufacturing processes for resin-based composite materials. There are three main forms of winding: circumferential winding, planar winding, and helical winding. Wet winding involves bundling and impregnating fibers with resin, then directly winding them onto a mandrel under tension control, followed by curing. While wet winding equipment is relatively simple, the immediate winding after impregnation makes it difficult to control and inspect the resin content in the product during the winding process. Furthermore, the solvent in the resin can easily form defects such as bubbles and pores in the product during curing, and tension control is also difficult. To achieve optimal strength in the composite pipe, the industry often uses manual stretching of the adhesive rope to scrape off excess resin. However, during manual operation, the operator's upper limbs inevitably come into contact with the rotating pipe being wound, leading to frequent accidents involving entangled hands.

[0003] Existing technologies also include specialized adhesive scraping devices for fiberglass pipes. For example, patent CN216506847U discloses a mobile adhesive scraping and collection device for fiberglass pipes, specifically disclosing the following technical details: It includes a frame, which is a rectangular three-dimensional structure with a fixed plate at its bottom and movable wheels at the bottom. A resin collection tank is mounted on the fixed plate, and a counterweight is fixed to the lower surface of the fixed plate. An adhesive scraper is mounted on the frame, pressing against the surface of the fiberglass pipe. An adjusting arm is connected to the rear end of the scraper via a connecting seat. The adjusting arm is connected to the frame and has limited rotation. The adjusting arm includes an adjusting rod and a connecting rod, which are fixedly connected by a fixed shaft. An adhesive receiving groove is located directly below the scraper and is fitted onto the frame. A spring device, consisting of three sets of springs, is located between the adhesive receiving groove and the adjusting arm. The spring device consists of three sets of springs, which are fixedly connected end-to-end. A collection slot is located at the end of the adhesive receiving groove, positioned above the resin collection tank for resin collection. In this existing patent, a force-operated scraper applies force to the rotating pipe to be coated using a force-operated scraper, thereby scraping the adhesive onto the pipe. However, in order to scrape the adhesive onto the entire pipe, the scraper must move along the length of the pipe. If the scraper moves too fast along the length of the pipe, it will not be able to scrape the entire pipe, affecting the quality of the pipe. If the speed is too slow, it will affect the efficiency of pipe production.

[0004] For example, the existing patent CN116572562B discloses a manufacturing process for continuously wound fiberglass pipes, which discloses the following technical contents: It includes a scraping drive unit and a pressing scraping unit. The scraping drive unit includes two fixed lugs fixedly disposed at both ends of a worktable and a drive motor fixedly mounted on one of the fixed lugs. The output shaft of the drive motor is fixedly connected to a lead screw, and the end of the lead screw away from the output shaft of the drive motor is rotatably connected to the fixed lug. A corresponding threaded sleeve is threadedly connected to the lead screw, and the threaded sleeve is slidably connected to the worktable. An electric telescopic rod is fixedly connected to the upper side wall of the threaded sleeve, and a manual telescopic rod is fixedly connected to the upper end of the side wall of the electric telescopic rod; the pressing scraping unit... The device includes a sleeve fitted over the outside of a fiberglass pipe and a ring installed inside the sleeve. The sleeve is fixedly connected to the end of a manual telescopic rod. A corresponding movable sleeve is fitted onto the ring. A fixing plate is fixedly installed on the inner wall of the movable sleeve. A drive motor is fixedly connected to one side of the fixing plate, and a gear column is fixedly connected to the output shaft of the drive motor. A ring rail that meshes with the gear column is formed on the ring. A fixing block is fixedly installed on the side of the movable sleeve away from the sleeve, and a pressure plate is fixedly installed on the side of the fixing block away from the center of the sleeve. A scraper is fixedly connected to the side of the fixing block away from the pressure plate. A glue drop pipe is fixedly connected to the lower end of the sleeve. A collection box is fixedly installed on the side wall of the worktable. Limiting plates are fixedly installed at both ends of the sleeve. In this patent, because the inner diameters of the ring and the movable sleeve are fixed, glue can only be scraped onto pipes of a fixed size. Furthermore, because the scraper needs to move in a circular motion with the ring and in a straight line along the length of the pipe to scrape the glue, uneven glue scraping can easily occur if the speeds of the circular and straight-line movements of the scraper are mismatched.

[0005] Therefore, in the existing technology, how to safely and efficiently scrape off excess resin during the composite pipe winding process has become a common problem in the industry. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide an automatic glue control equipment for manufacturing fiberglass pipes, which automatically scrapes off excess unsaturated resin on the surface during the composite pipe winding process, thereby improving the safety and quality of glue scraping.

[0007] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: An automatic glue control device for manufacturing fiberglass pipes includes a glue receiving trolley, a glue scraping rope, and a tension adjustment mechanism. The glue receiving trolley is used to receive glue scraped from the core mold when it is positioned below the core mold. A bracket is fixedly provided on the glue receiving trolley, and the tension adjustment mechanism is fixedly provided on the bracket. The middle part of the glue scraping rope is used to be positioned below the core mold, and both ends of the glue scraping rope are fixedly connected to the tension adjustment mechanism. The tension adjustment mechanism drives the two ends of the glue scraping rope to be arranged crosswise above the core mold, so that the glue scraping rope surrounds the core mold.

[0008] The beneficial effects of this invention are as follows: This invention realizes automatic glue scraping. Compared with manual glue scraping, it firstly achieves "machine replacing man" in pipe glue scraping, fundamentally eliminating the safety hazard of mechanical hand entanglement causing injury, reducing enterprise safety management costs, and improving management efficiency; to a certain extent, it maintains a constant tension of the glue scraping rope on the pipe, ensuring the glue scraping effect, directly reducing the manufacturing cost of composite pipes, and improving the quality of fiberglass pipes.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the tension adjustment mechanism is provided in two sets, with the two sets of tension adjustment mechanisms spaced apart along the length of the core mold, and each set of tension adjustment mechanisms is connected to a scraping rope.

[0011] The beneficial effects of adopting the above-mentioned further solution are as follows: the tension adjustment mechanism is set into two sets, which are located on both sides of the fiber bundled wire. During the movement of the pipe, since the outer diameter of the pipe behind the fiber bundled wire is the same, the corresponding scraping rope is adjusted by the tension adjustment mechanism located behind the fiber bundled wire to scrape the glue, while the tension adjustment mechanism located in front of the fiber bundled wire is released. This ensures that the glue is scraped under constant tension, ensuring the uniformity of the glue scraping, thereby ensuring the manufacturing quality of the fiberglass pipe.

[0012] Furthermore, the tension adjustment mechanism includes two linear motion components, which are fixedly mounted above the glue-receiving trolley at intervals via the bracket. The ends of the output shafts of the two linear motion components are respectively fixedly connected to the two ends of the glue-scraping rope, and the extension lines of the output shafts of the two linear motion components are arranged to cross each other.

[0013] The advantages of adopting the above-mentioned further solution are: the linearly moving output shaft drives the two ends of the scraping rope to be arranged in a cross shape, thereby realizing the wrapping of the fiberglass pipe. The structure is simple and the operation is convenient.

[0014] Furthermore, the linear motion component is a linear motor, a pneumatic cylinder, or a hydraulic cylinder.

[0015] The advantages of adopting the above-mentioned further solutions are: simple structure, wide availability, and low cost.

[0016] Furthermore, the end of the output shaft of the linear motion component is connected to the scraping rope via a tension sensor.

[0017] The beneficial effects of adopting the above-mentioned further solution are: the setting of the tension sensor can accurately detect the winding tension on the pipe, and thus can control the output length of the output shaft of the linear motion mechanism as needed, thereby ensuring that the tension of the scraping rope is kept within a certain range and ensuring the quality of the FRP pipe.

[0018] Furthermore, the tension adjustment mechanism includes an arc-shaped support frame with its inner arc-shaped surface facing downwards. Two sliding seats are slidably mounted on the arc-shaped support frame, and the two sliding seats are respectively fixedly connected to both ends of the scraping rope. The arc-shaped support frame is provided with a driving mechanism for driving the two sliding seats to move away from or closer to each other along the inner arc-shaped surface of the arc-shaped support frame.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the driving mechanism drives the sliding seats to move away from or closer to each other along the inner arc surface of the arc support frame, thereby realizing the wrapping or loosening of the fiberglass pipe and the wrapping of the fiberglass pipe with adhesive.

[0020] Furthermore, the arc-shaped support frame includes two spaced arc-shaped racks, the driving mechanism includes a drive motor, the two arc-shaped racks are arranged in parallel, the two ends of the two arc-shaped racks are fixedly connected to the bracket, the sides of the arc-shaped racks are provided with arc-shaped guide rails, the arc-shaped guide rails are provided with sliding seats that can reciprocate along the extension direction of the arc-shaped guide rails, the scraping rope is connected to the bottom end of the sliding seat, the drive motor is fixedly mounted on the sliding seat, and a gear is fixedly mounted on the output shaft of the drive motor, the gear meshing with the arc-shaped racks.

[0021] The beneficial effects of adopting the above-mentioned further solution are: the drive motor, through gear and rack transmission and arc rack transmission, enables the sliding seat to move along the arc guide rail, thereby achieving precise adjustment of the sliding seat position, and thus enabling the scraping rope to cross-wrap around and loosen the fiberglass pipe.

[0022] Furthermore, the outer arc surface of the arc-shaped guide rail is provided with an outer arc groove, the inner surface of the arc-shaped guide rail is provided with an inner arc groove, and an outer roller and an inner roller are rotatably provided on one side surface of the sliding seat. The outer roller rolls in the outer arc groove, and the inner roller rolls in the inner arc groove.

[0023] The beneficial effect of adopting the above-mentioned further solution is that it realizes the rolling connection between the sliding seat and the arc-shaped guide rail, and reduces the friction between the sliding seat and the arc-shaped guide rail.

[0024] Furthermore, at least one of the sliding seats is fixedly equipped with a take-up motor, the output shaft of the take-up motor is fixedly equipped with a take-up roller, and one end of the scraper rope is fixedly connected to the take-up roller.

[0025] The beneficial effect of adopting the above-mentioned further solution is that the take-up motor can take up and release the scraper rope as needed, which facilitates the tension adjustment of the scraper rope.

[0026] Furthermore, it also includes a controller, which is electrically connected to the tension adjustment mechanism and is used to control the opening and closing of the tension adjustment mechanism.

[0027] The beneficial effect of adopting the above-mentioned further solution is that the controller setting facilitates the control of the tension adjustment mechanism. Attached Figure Description

[0029] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] Example 1 like Figure 1 , Figure 2 As shown, this embodiment includes a glue-receiving trolley 1, a glue-scraping rope 2, and a tension adjustment mechanism. The glue-receiving trolley 1 is positioned below the core mold 3 to receive the glue scraped from the core mold 3. The glue-receiving trolley 1 can be moved by the moving wheels at the bottom, or by the sliding rail and groove structure at the bottom to move along the length of the core mold 3, or it can be fixedly connected to the winding trolley. When the glue-receiving trolley 1 moves by itself, it can be driven by a motor to drive the moving wheels, or it can be directionally moved by a lead screw, gear, or rack.

[0031] The glue-applying trolley 1 is fixedly equipped with a bracket 4, and the tension adjustment mechanism is fixedly equipped on the bracket 4. The middle part of the glue-scraping rope 2 is used to be placed below the core mold 3. Both ends of the glue-scraping rope 2 are fixedly connected to the tension adjustment mechanism. The tension adjustment mechanism drives the two ends of the glue-scraping rope 2 to be arranged crosswise above the core mold 3, so that the glue-scraping rope 2 surrounds the core mold 3.

[0032] In this embodiment, there are two sets of tension adjustment mechanisms, which are spaced apart along the length of the mandrel 3. Each set of tension adjustment mechanisms is connected to a scraping rope 2. The two sets of tension adjustment mechanisms are located on both sides of the fiber-wound wire. During pipe movement, since the outer diameter of the pipe behind the fiber-wound wire is the same, the corresponding scraping rope 2 is adjusted by the tension adjustment mechanism located behind the fiber-wound wire to scrape the adhesive, while the tension adjustment mechanism located in front of the fiber-wound wire is released. This ensures that the adhesive is scraped under constant tension, ensuring the uniformity of the adhesive scraping and thus ensuring the manufacturing quality of the fiberglass pipe.

[0033] The tension adjustment mechanism includes two linear motion components 5, which are fixedly mounted above the glue-receiving trolley 1 at intervals via the bracket 4. The ends of the output shafts of the two linear motion components 5 are respectively fixedly connected to the two ends of the glue-scraping rope 2, and the extension lines of the output shafts of the two linear motion components 5 are arranged intersectingly. The linearly moving output shafts drive the two ends of the glue-scraping rope 2 to be arranged intersectingly, thereby achieving the wrapping of the fiberglass pipe. The structure is simple and the operation is convenient.

[0034] In this embodiment, the linear motion component 5 is a linear motor, a pneumatic cylinder, or a hydraulic cylinder, which has a simple structure, is widely available, and has low cost. When the linear motion mechanism is a pneumatic cylinder or a hydraulic cylinder, an air source or hydraulic source, such as an air pump or a hydraulic pump, is fixedly provided on the glue-receiving carriage 1 to realize the follow-up movement of the air source or hydraulic source with the glue-receiving carriage 1.

[0035] The end of the output shaft of the linear motion component 5 is connected to the scraper rope 2 via a tension sensor 17. The tension sensor 17 can accurately detect the winding tension on the pipe, and thus control the output length of the output shaft of the linear motion mechanism as needed, thereby ensuring that the tension of the scraper rope 2 is kept within a certain range and ensuring the quality of the fiberglass pipe.

[0036] In this embodiment, a controller is also included. The controller is electrically connected to the tension adjustment mechanism and is used to control the opening and closing of the tension adjustment mechanism. The controller is also connected to the linear motion mechanism and is used to control the extension and retraction of the output shaft of the linear motion mechanism. The controller is connected to the tension sensor 17 and is used to receive the tension signal detected by the tension sensor 17. Based on the received tension signal, the controller controls the extension and retraction of the output shaft of the linear motion mechanism. On the one hand, it can automatically adjust the extension length of the output shaft of the linear motion mechanism after the outer diameter of the pipe increases due to the winding of fiber bundles. On the other hand, it can ensure that the tension of the scraping rope 2 is kept within a certain range, thus ensuring the quality of the fiberglass pipe.

[0037] Working principle: After the fiber bundle is impregnated with resin, one end is placed on the mandrel 3. A motor drives the mandrel 3 to rotate axially, simultaneously causing the winding carriage to move back and forth along the length of the mandrel 3, thus gradually winding the fiber bundle onto the mandrel 3. During the winding process, in the two tension adjustment mechanisms, the output shaft of the linear movement mechanism of the tension adjustment mechanism located in front of the connection between the fiber bundle and the mandrel 3 retracts, causing the scraper rope 2 on the front tension adjustment mechanism to detach from the mandrel 3. The output shaft of the linear movement mechanism of the tension adjustment mechanism located behind the connection between the fiber bundle and the mandrel 3 extends, causing the scraper rope 2 of the rear tension adjustment mechanism to wind around the mandrel 3, scraping off excess resin from the fiber bundle on the mandrel 3. Figure 1 As shown, when the glue scraping trolley moves to the right along with the winding trolley, the output shaft of the linear motion mechanism in the tension adjustment mechanism on the left extends, causing the glue scraping rope 2 to wrap around the mandrel 3 for glue scraping, while the output shaft of the linear motion mechanism in the tension adjustment mechanism on the right retracts; Figure 2 As shown, when the glue scraping trolley moves to the left along with the winding trolley, the output shaft of the linear movement mechanism in the tension adjustment mechanism on the right extends, causing the glue scraping rope 2 to wrap around the core mold 3 for glue scraping, and the output shaft of the linear movement mechanism in the tension adjustment mechanism on the left retracts.

[0038] This invention achieves automatic glue application, which, compared to manual glue application, firstly, replaces manual glue application with automated methods, fundamentally eliminating the safety hazard of mechanical handles causing injury, reducing enterprise safety management costs, and improving management efficiency; secondly, it maintains a constant tension of the glue application rope 2 on the pipe to a certain extent, ensuring the glue application effect, directly reducing the manufacturing cost of composite pipes, and improving the quality of FRP pipes; the commissioning and use of this equipment directly reduces the manufacturing cost of composite pipes, thereby giving composite pipes a stronger market competitiveness and broad application prospects.

[0039] Example 2 like Figure 3 , Figure 4 , Figure 5As shown, this embodiment includes a glue-receiving trolley 1, a glue-scraping rope 2, and a tension adjustment mechanism. The glue-receiving trolley 1 is positioned below the core mold 3 to receive the glue scraped from the core mold 3. The glue-receiving trolley 1 can be moved by the moving wheels at the bottom, or by the sliding rail and groove structure at the bottom to move along the length of the core mold 3, or it can be fixedly connected to the winding trolley. When the glue-receiving trolley 1 moves by itself, it can be driven by a motor to drive the moving wheels, or it can be directionally moved by a lead screw, gear, or rack.

[0040] The glue-applying trolley 1 is fixedly equipped with a bracket 4, and the tension adjustment mechanism is fixedly equipped on the bracket 4. The middle part of the glue-scraping rope 2 is used to be placed below the core mold 3. Both ends of the glue-scraping rope 2 are fixedly connected to the tension adjustment mechanism. The tension adjustment mechanism drives the two ends of the glue-scraping rope 2 to be arranged crosswise above the core mold 3, so that the glue-scraping rope 2 surrounds the core mold 3.

[0041] In this embodiment, there are two sets of tension adjustment mechanisms, which are spaced apart along the length of the mandrel 3. Each set of tension adjustment mechanisms is connected to a scraping rope 2. The two sets of tension adjustment mechanisms are located on both sides of the fiber-wound wire. During pipe movement, since the outer diameter of the pipe behind the fiber-wound wire is the same, the corresponding scraping rope 2 is adjusted by the tension adjustment mechanism located behind the fiber-wound wire to scrape the adhesive, while the tension adjustment mechanism located in front of the fiber-wound wire is released. This ensures that the adhesive is scraped under constant tension, ensuring the uniformity of the adhesive scraping and thus ensuring the manufacturing quality of the fiberglass pipe.

[0042] In this embodiment, the tension adjustment mechanism includes an arc-shaped support frame with its inner arc-shaped surface facing downwards. Two sliding seats 6 are slidably mounted on the arc-shaped support frame, and the two sliding seats 6 are respectively fixedly connected to both ends of the adhesive scraping rope 2. The arc-shaped support frame is provided with a driving mechanism for moving the two sliding seats 6 away from or closer to each other along the inner arc-shaped surface of the arc-shaped support frame. By driving the sliding seats 6 away from or closer to each other along the inner arc-shaped surface of the arc-shaped support frame through the driving mechanism, the fiberglass pipe can be wrapped around or loosened, thereby achieving the wrapping and scraping of adhesive around the fiberglass pipe.

[0043] Specifically, the arc-shaped support frame includes two spaced-apart arc-shaped racks 7, with teeth on their outer arc surfaces. The driving mechanism includes a drive motor 8. The two arc-shaped racks 7 are arranged in parallel, and their two ends are fixedly connected to the bracket 4. Arc-shaped guide rails 9 are provided on the sides of each arc-shaped rack 7, and these guide rails are integrated with the racks. A sliding seat 6, which can reciprocate along the extension direction of the guide rail 9, is provided on the guide rail 9. The adhesive scraping rope 2 is connected to the bottom end of the sliding seat 6. The drive motor 8 is fixedly mounted on the sliding seat 6, and a gear 10 is fixedly mounted on the output shaft of the drive motor 8. The gear 10 meshes with the arc-shaped racks 7. The drive motor 8 drives the arc-shaped racks 7 via the gear 10, thereby enabling the sliding seat 6 to move along the arc-shaped guide rail 9, achieving precise adjustment of the sliding seat 6's position, and thus enabling the adhesive scraping rope 2 to cross-wrap and loosen around the fiberglass pipe.

[0044] In this embodiment, the outer arc surface of the arc-shaped guide rail 9 is provided with an outer arc groove 11, and the inner surface of the arc-shaped guide rail 9 is provided with an inner arc groove 12. An outer roller 13 and an inner roller 14 are rotatably provided on one side surface of the sliding seat 6. There are multiple outer rollers 13 and multiple inner rollers 14, with the outer rollers 13 positioned outside the inner rollers 14. The outer rollers 13 roll within the outer arc groove 11, and the inner rollers 14 roll within the inner arc groove 12. The outer rollers 13 and inner rollers 14 clamp the arc-shaped guide rail 9, thereby limiting and sliding the sliding seat 6 onto the arc-shaped guide rail 9. This achieves a rolling connection between the sliding seat 6 and the arc-shaped guide rail 9, reducing friction between them.

[0045] In this embodiment, a take-up motor 15 is fixedly mounted on one of the sliding seats 6, and a take-up roller 16 is fixedly mounted on the output shaft of the take-up motor 15. One end of the scraper rope 2 is fixedly connected to the take-up roller 16. A tension sensor 17 is fixedly mounted on the other sliding seat 6, and the other end of the scraper rope 2 is connected to the sliding seat 6 through the tension sensor 17. The take-up motor 15 can take up and release the scraper rope 2 as needed, facilitating the tension adjustment of the scraper rope 2.

[0046] In this embodiment, a controller is also included. The controller is electrically connected to the tension adjustment mechanism and is used to control the opening and closing of the tension adjustment mechanism. Specifically, the controller is connected to the drive motor 8, the take-up motor 15, and the tension sensor 17. The controller is connected to the take-up motor 15 and is used to control the drive motor 8 or the take-up motor 15 to rotate based on the tension signal detected by the tension sensor 17. On the one hand, it can automatically adjust the extension length of the output shaft of the linear movement mechanism after the outer diameter of the pipe increases due to the winding of the fiber bundle. On the other hand, it can ensure that the tension of the scraping rope 2 is kept within a certain range, thus ensuring the quality of the fiberglass pipe.

[0047] Working Principle: After the fiber bundle is impregnated with resin, one end is placed on the mandrel 3. A motor drives the mandrel 3 to rotate axially, simultaneously causing the winding carriage to move back and forth along the length of the mandrel 3, thus gradually winding the fiber bundle onto the mandrel 3. During the winding process, in the two tension adjustment mechanisms, the drive mechanism in the tension adjustment mechanism located in front of the connection between the fiber bundle and the mandrel 3 moves the sliding seat 6, causing the scraper rope 2 on the front tension adjustment mechanism to detach from the mandrel 3. The drive mechanism in the tension adjustment mechanism located behind the connection between the fiber bundle and the mandrel 3 moves the sliding seat 6, causing the scraper rope 2 of the rear tension adjustment mechanism to wind around the mandrel 3, scraping off excess resin from the fiber bundle on the mandrel 3. Figure 3 As shown, when the glue scraping trolley moves to the right along with the winding trolley, the drive mechanism in the tension adjustment mechanism on the left moves the sliding seat 6, causing the glue scraping rope 2 to wrap around the core mold 3 for glue scraping. The drive mechanism in the tension adjustment mechanism on the right moves the sliding seat 6, causing the glue scraping rope 2 on the right tension adjustment mechanism to detach from the core mold 3. When the glue scraping trolley moves to the left along with the winding trolley, the drive mechanism in the tension adjustment mechanism on the right moves the sliding seat 6, causing the glue scraping rope 2 to wrap around the core mold 3 for glue scraping. The drive mechanism in the tension adjustment mechanism on the left moves the sliding seat 6, causing the glue scraping rope 2 on the left tension adjustment mechanism to detach from the core mold 3.

[0048] This invention achieves automatic glue application, which, compared to manual glue application, firstly, replaces manual glue application with automated methods, fundamentally eliminating the safety hazard of mechanical handles causing injury, reducing enterprise safety management costs, and improving management efficiency; secondly, it maintains a constant tension of the glue application rope 2 on the pipe to a certain extent, ensuring the glue application effect, directly reducing the manufacturing cost of composite pipes, and improving the quality of FRP pipes; the commissioning and use of this equipment directly reduces the manufacturing cost of composite pipes, thereby giving composite pipes a stronger market competitiveness and broad application prospects.
