Description

Technical Field

[0001] The present invention belongs to the technical field of fiberglass grating production, and particularly relates to an automatic production device for fiberglass gratings. Background Art

[0002] Fiberglass (abbreviation: FRP) grating, also known as fiberglass grid plate, is a plate-like material with many spaces, which is made of glass fiber as the reinforcing material and unsaturated polyester resin as the matrix through special processing and compounding. Fiberglass gratings can be used as structural materials, such as floors, trench covers, platforms, warship decks, stairs, and plank roads in corrosive environments. They have the characteristics of corrosion resistance, flame retardancy, non-magnetic insulation, bright colors, and multiple style forms to choose from.

[0003] In the prior art, during the production of fiberglass gratings, first, workers pour the resin mixture into the molding die of the fiberglass grating, then lay the glass fiber filaments into the grooves of the molding die through a wire laying tool, and then manually draw the wires to lay the raw materials evenly, and then heat and form. The entire production process is carried out manually, with low efficiency and prone to problems such as missed laying and re-laying.

[0004] In view of this, the present invention proposes an automatic production device for fiberglass gratings to solve the above technical problems. Summary of the Invention

[0005] In order to solve the deficiencies of the prior art, the present invention provides an automatic production device for fiberglass gratings, including: a base for fixing the die, and the surface of the die is provided with criss-cross grooves; a wire laying mechanism, including a frame, a plurality of driving components, a plurality of wire laying components and a moving component; the wire laying components correspond to the driving components one by one, and the wire laying components are movably connected to the lower end surface of the frame through the driving components, and the driving components control the wire laying components to move along the width direction of the die; the wire laying components include a mounting plate, a wire laying head and a wire feeding roller group, the wire laying head is arranged on one side of the mounting plate, an installation cavity is arranged at the lower end of the mounting plate, a mixing cavity is arranged in the wire laying head, a liquid injection port for the mixed resin to enter is arranged on the upper wall of the mixing cavity, a guiding port is arranged on one side of the mixing cavity close to the wire feeding roller group, and a wire laying port is arranged at the bottom of the side far from the wire feeding roller group, and the height of the wire laying port is lower than that of the guiding port; the wire feeding roller group is arranged in the installation cavity to draw the glass fiber filaments towards the wire laying port; the wire laying port faces the grooves of the die to directionally lay the glass fiber filaments impregnated with the mixed resin into the grooves; the moving component is connected to the lower end of the frame to drive the wire laying mechanism to move along the length direction of the die. Through the semi-automatic design, the production efficiency is improved, manual operation is reduced, problems such as uneven wire laying caused by unskilled manual operation are reduced, and the quality of fiberglass gratings is guaranteed.

[0006] Furthermore, the upper end of the frame is equipped with multiple payoff rollers and corresponding storage buckets. Glass fiber filaments are wound around the payoff rollers, and mixed resin is contained in the storage buckets. A vertically extending feed port is defined below the payoff rollers. The glass fiber filaments pass through the feed port and are pulled toward the laydown port by the wire feed roller assembly. The storage buckets are connected to the liquid injection port. This simplifies the production process, reduces material transfer steps, reduces production costs, and improves production efficiency and equipment stability.

[0007] Furthermore, the fiber placement assembly also includes an electric push rod, a rotating platform, and a motor. The telescopic end of the electric push rod is connected to the upper surface of the mounting plate to control the elevation of the mounting plate. The fixed end of the electric push rod is connected to the lower end of the rotating platform. The motor's rotating shaft is connected to the upper end of the rotating platform, allowing the rotating platform to rotate about a vertical axis to adjust the horizontal orientation of the fiber placement head. This enhances the adaptability of the equipment, enabling precise adjustments based on the mold shape and fiber placement requirements, meeting the production needs of fiberglass gratings of different specifications and shapes, and improving the equipment's versatility and flexibility.

[0008] Furthermore, the spacing between adjacent placement heads is an integer multiple of the spacing between adjacent grooves in the mold. The placement assembly, through step-by-step movement of the moving assembly, allows all placement heads to simultaneously move to the next adjacent groove after completing placement in the current groove, continuing until all grooves are laid. This improves placement efficiency, reduces the distance the placement heads must travel between grooves, reduces glass fiber consumption, and ensures uniform and continuous placement.

[0009] Furthermore, the wire feed roller assembly includes a vertical wire feed roller and a horizontal wire feed roller. The vertical wire feed roller's feed end is located directly below the feed port, while the horizontal wire feed roller's feed end connects to the vertical wire feed roller's discharge end, which extends to the guide port. The horizontal wire feed roller is connected to a power source to provide traction power for the glass fiber filaments through rotation. This improves the stability and accuracy of the wire placement process and reduces production interruptions and quality issues caused by poor glass fiber filament feeding.

[0010] Furthermore, the drive assembly is a linear motor or a ball screw module, which provides precise drive control for the device and can achieve high-precision motion control to ensure the precise position of the wire placement assembly on the mold.

[0011] Further, the driving assembly includes a reciprocating lead screw, a slider, a synchronous belt drive group, a flexible shaft and a runner; the runner is arranged outside the frame, the reciprocating lead screw is installed at the lower end of the frame, the slider is in threaded fit with the reciprocating lead screw and reciprocates when the reciprocating lead screw rotates, and the lower end of the slider is fixedly connected to the wire laying head; the synchronous belt drive group includes a driving gear, a first driven gear, a second driven gear and a synchronous belt, the first driven gear is coaxially connected to one end of the reciprocating lead screw, the second driven gear is rotatably installed on the frame, the second driven gear is connected to the horizontal wire feeding roller through a flexible shaft to drive its rotation, and the driving gear is coaxially connected to the runner; when the runner rotates, the synchronous belt drives the first driven gear and the second driven gear to rotate, so as to realize the movement of the reciprocating lead screw and the horizontal wire feeding roller. The runner is driven by a motor or manually rotated. When power is cut off or manual operation is required, the runner can be manually rotated to drive the equipment to lay wires, improving the emergency response ability and reliability of the equipment.

[0012] Further, the wire laying assembly further includes a manually controlled telescopic rod and a rotating joint. The fixed end of the telescopic rod is connected to the upper surface of the mounting plate, and the telescopic end of the telescopic rod is connected to the rotating joint. The rotating joint can rotate around the vertical axis to adjust the horizontal orientation of the wire laying head.

[0013] Further, the surface of the wire feeding roller in the wire feeding roller group is provided with axially distributed raised stripes.

[0014] Further, it further includes a mobile power source for providing power, and the mobile power source is arranged on the side of the frame.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. Through the semi-automatic design of the wire laying mechanism and the collaborative work of the driving assembly, the moving assembly, etc., the present invention can realize the automatic laying of fiberglass filaments, reduce the manual operation links, improve the production efficiency, and the equipment can continuously carry out wire laying operations, avoiding the production interruption or low efficiency problems caused by factors such as personnel fatigue and unskilled operation in the traditional manual wire laying method. It can operate stably for a long time, ensuring the continuous production of fiberglass grids. The reasonable configuration of the wire feeding roller group and the driving assembly in the wire laying assembly can accurately control the laying speed and tension of the fiberglass filaments, so that the filament bundle is evenly laid in the mold groove, improving the wire laying quality.

[0017] 2. The distance between adjacent wire laying heads of the present invention can be adjusted according to the distance between adjacent grooves of the mold (four times, six times or eight times), and the wire laying of all grooves is completed by the step-by-step movement of the moving assembly, improving the adaptability of the equipment to different specifications of molds, meeting the production needs of diversified products, and ensuring the consistency and stability of product quality.

DETAILED DESCRIPTION OF THE INVENTION

[0027] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] The present invention discloses an automatic production device for fiberglass grids, including: a base 1 for fixing a mold 2, and the surface of the mold 2 is provided with criss-crossed grooves; a wire laying mechanism 3, including a frame 31, a plurality of driving components 32, a plurality of wire laying components 33 and a moving component 34; the wire laying components 33 correspond to the driving components 32 one by one, and the wire laying components 33 are movably connected to the lower end surface of the frame 31 through the driving components 32, and the driving components 32 control the wire laying components 33 to move along the width direction of the mold 2; the wire laying component 33 includes a mounting plate 331, a wire laying head 332 and a wire feeding roller group 333, the wire laying head 332 is arranged on one side of the mounting plate 331, a mounting cavity is arranged at the lower end of the mounting plate 331, a mixing cavity is arranged in the wire laying head 332, a liquid injection port 335 for mixing resin to enter is arranged on the upper wall of the mixing cavity, a guiding port 334 is arranged on one side of the mixing cavity close to the wire feeding roller group 333, and a wire laying port 336 is arranged at the bottom of the side far from the wire feeding roller group 333, and the height of the wire laying port 336 is lower than that of the guiding port 334; the wire feeding roller group 333 is arranged in the mounting cavity to draw the fiberglass filaments to move towards the wire laying port 336; the wire laying port 336 faces the grooves of the mold 2 to directionally lay the fiberglass filaments impregnated with the mixed resin into the grooves; the moving component 34 is connected to the lower end of the frame 31 to drive the wire laying mechanism 3 to move along the length direction of the mold 2.

[0029] During operation, the mold 2 is fixed on the base 1 to ensure that the criss-crossed grooves on the surface of the mold are in a proper position and state for subsequent laying of fiberglass filaments. One end of the fiberglass filament is manually passed through the wire feeding roller group 333, and the mixed resin enters the mixing cavity through the liquid injection port 335 and is fully impregnated with the fiberglass filaments in the mixing cavity, so that the fiberglass filaments are evenly wrapped with the mixed resin. The impregnated fiberglass filaments enter the wire laying port 336 from the guiding port 334 of the mixing cavity. Since the height of the wire laying port 336 is lower than that of the guiding port 334, the fiberglass filaments are directionally laid into the grooves of the mold 2 from the wire laying port 336 under the action of gravity and the traction force of the wire feeding roller group 333. During the wire laying process, the driving component 32 controls the wire laying component 33 to move along the width direction of the mold 2 to realize the laying of fiberglass filaments in the width direction of the mold 2.

[0030] The present invention reduces the cumbersome steps of manual operation through a semi-automatic design, greatly improves the production speed of fiberglass grids, and also reduces the defective rate caused by non-standard manual operation. The fiberglass filaments are fully impregnated with the mixed resin in the mixing cavity, ensuring the uniform mixing of the fiberglass filaments and the resin, and guaranteeing the appearance quality and dimensional accuracy of the product.

[0031] As one of the embodiments of the present invention, a plurality of wire feeding rollers 4 and storage barrels 5 corresponding to the wire feeding rollers 4 one by one are provided at the upper end of the frame 31. The surface of the wire feeding roller 4 is wound with fiberglass filaments, and the storage barrel 5 is filled with mixed resin. The frame 31 is provided with a vertically penetrating material opening below the wire feeding roller 4. The fiberglass filaments pass through the material opening and are pulled by the wire feeding roller group 333 towards the wire laying opening 336; the storage barrel 5 is communicated with the liquid injection port 335.

[0032] Through the plurality of wire feeding rollers 4 and storage barrels 5 on the frame 31, the continuous supply of fiberglass filaments and mixed resin is realized, avoiding production stagnation caused by material interruption, and further improving the continuity and stability of production.

[0033] As an implementation manner of the present invention, as Figure 2 shown, the wire laying assembly 33 further includes an electric push rod 6, a rotating platform 7 and a motor 8. The telescopic end of the electric push rod 6 is connected to the upper surface of the mounting plate 331 to control the lifting of the mounting plate 331. The fixed end of the electric push rod 6 is connected to the lower end of the rotating platform 7, and the rotating shaft of the motor 8 is connected to the upper end surface of the rotating platform 7, so that the rotating platform 7 can rotate around the vertical axis to adjust the horizontal orientation of the wire laying head 332.

[0034] The horizontal orientation and height of the wire laying head can be flexibly adjusted. This enables the equipment to quickly and accurately adjust the position of the wire laying head according to the different distributions of the grooves on the mold and the production requirements, adapting to the production of fiberglass gratings of different specifications and shapes, and enhancing the versatility and adaptability of the equipment. When it is necessary to adjust the horizontal orientation of the wire laying head 332, the rotating shaft of the motor 8 starts to rotate, driving the connected rotating platform 7 to rotate around the vertical axis. Since the fixed end of the electric push rod 6 is connected to the lower end of the rotating platform 7 and the mounting plate 331 is connected to the telescopic end of the electric push rod 6, the rotation of the rotating platform 7 will drive the electric push rod 6 and the mounting plate 331 to rotate together, thereby realizing the adjustment of the horizontal orientation of the wire laying head 332, enabling it to accurately align with the grooves at different positions on the surface of the mold 2 and meeting the requirements of wire laying in different directions. During the wire laying process, the lifting of the electric push rod 6 is controlled according to the actual production needs. When the telescopic end extends, the mounting plate 331 rises along the vertical direction, driving the wire laying head 332 to rise together, thereby adjusting the vertical distance between the wire laying head 332 and the mold 2 to adapt to the production requirements of fiberglass gratings of different thicknesses; when the telescopic end shortens, the mounting plate 331 descends, and the wire laying head 332 also descends, approaching the mold 2 to ensure that the fiberglass filaments can be accurately laid into the grooves of the mold 2.

[0035] As an embodiment of the present invention, the distance between adjacent wire laying heads 332 is an integer multiple of the distance between adjacent grooves of the mold 2, and the wire laying assembly 33 is stepwise moved by the moving assembly 34, so that after all the wire laying heads 332 complete wire laying in the current groove, they can be simultaneously transferred to the adjacent next groove for wire laying until all the grooves are wire laid.

[0036] The wire laying heads 332 of the wire laying assembly 33 start to lay wires according to the set distance and sequence. During the wire laying process, the moving assembly 34 drives the wire laying assembly 33 to move along the length direction of the mold 2 in a stepwise manner. The distance of each movement is manually controlled according to the distance between adjacent grooves of the mold 2 and the distance between the wire laying heads 332. For example, when the distance between adjacent wire laying heads 332 is four times the distance between adjacent grooves of the mold, the distance that the moving assembly 34 drives the wire laying assembly 33 to move each time is the distance between adjacent grooves of the mold, so that each wire laying head 332 can be aligned with each groove on the mold 2 in turn for wire laying. During the movement, the wire laying heads 332 continuously lay the glass fiber filaments impregnated with the mixed resin into the grooves of the mold 2. With the stepwise movement of the moving assembly 34, the wire laying heads 332 sequentially complete the wire laying work for all the grooves on the mold 2, ensuring that the glass fiber filaments can be evenly laid in each groove. That is, assuming that originally two wire layings were to be achieved and the wire laying head needed to move from the first groove to the fifth groove, now each wire laying head only needs to move from the first groove to the second groove, reducing the consumption of glass fiber filaments during the movement between the grooves.

[0037] As an embodiment of the present invention, the wire feeding roller group 333 includes a vertical wire feeding roller 3331 and a horizontal wire feeding roller 3332. The feeding end of the vertical wire feeding roller 3331 is arranged directly below the material port, the feeding end of the horizontal wire feeding roller 3332 is connected to the discharging end of the vertical wire feeding roller 3331, and the discharging end of the horizontal wire feeding roller 3332 extends to the guiding port 334; the horizontal wire feeding roller is connected with a power source to provide traction power for the glass fiber filaments through rotation.

[0038] As Figure 2As shown in the figure, the vertically penetrating line represents the glass fiber filament. After being released from the wire feeding roller 4, the glass fiber filament droops naturally through the material inlet. The feeding end of the vertical wire feeding roller 3331 is located directly below the material inlet, and the glass fiber filament directly falls onto the vertical wire feeding roller 3331 to start the initial guiding process. The vertical wire feeding roller 3331 guides the glass fiber filament to keep it vertically downward for transportation, ensuring that the glass fiber filament can smoothly transition from the material inlet to the horizontal wire feeding roller 3332. After the glass fiber filament is output from the discharging end of the vertical wire feeding roller 3331, the feeding end of the horizontal wire feeding roller 3332 is connected to it, and the glass fiber filament is smoothly transferred to the horizontal wire feeding roller. The power source connected to the horizontal wire feeding roller starts to work, providing traction power for the glass fiber filament by rotation, so that the glass fiber filament is transported forward along the horizontal wire feeding roller and finally extends from the discharging end of the horizontal wire feeding roller to the guiding port 334.

[0039] As an embodiment of the present invention, as Figure 3 shown, the driving assembly 32 includes a reciprocating lead screw 321, a slider 322, a synchronous belt drive group, a flexible shaft 323, and a runner 324; the runner 324 is arranged outside the frame 31, the reciprocating lead screw 321 is rotatably installed at the lower end of the frame 31, the slider 322 is in threaded cooperation with the reciprocating lead screw 321 and reciprocates when the reciprocating lead screw 321 rotates, and the lower end of the slider 322 is fixedly connected to the wire laying head 332; the synchronous belt drive group includes a driving gear 325, a first driven gear 326, a second driven gear 327, and a synchronous belt. The first driven gear 326 is coaxially connected to one end of the reciprocating lead screw 321, the second driven gear 327 is rotatably installed on the frame 31, the second driven gear 327 is connected to the horizontal wire feeding roller through the flexible shaft 323 to drive its rotation, and the driving gear 325 is coaxially connected to the runner 324; when the runner 324 rotates, the synchronous belt drives the first driven gear 326 and the second driven gear 327 to rotate, thereby realizing the movement of the reciprocating lead screw 321 and the horizontal wire feeding roller.

[0040] The runner 324 can be driven by a motor. When the factory power supply fails and continuous operation is required, the runner 324 can be rotated manually. When the runner 324 rotates, the driving gear 325 coaxially connected to it rotates together. The rotation of the driving gear 325 drives the first driven gear 326 and the second driven gear 327 to rotate through a synchronous belt. Since the first driven gear 326 is coaxially connected to one end of the reciprocating lead screw 321, when the first driven gear 326 rotates, the reciprocating lead screw 321 also rotates accordingly. When the reciprocating lead screw 321 rotates, the slider 322 threadedly engaged with it makes a reciprocating linear motion on the guide rail at the lower end of the frame 31. The lower end of the slider 322 is fixedly connected to the wire laying head 332. Therefore, the reciprocating movement of the slider 322 drives the wire laying head 332 to make a reciprocating motion at the lower end of the frame 31, realizing the horizontal or vertical movement of the wire laying head 332 on the surface of the mold 2, so as to lay the glass fiber filaments at different groove positions. At the same time, the second driven gear 327 is connected to the horizontal wire feeding roller through a flexible shaft 323. When the second driven gear 327 rotates, the horizontal wire feeding roller is driven to rotate through the transmission of the flexible shaft 323. The rotation of the horizontal wire feeding roller provides traction power for the glass fiber filaments, enabling the glass fiber filaments to be smoothly conveyed from the discharge end of the vertical wire feeding roller to the guiding port 334 and finally laid into the grooves of the mold 2. The wire laying speed can be reduced in the manual mode to ensure the production continuity in the emergency state. The top of the slider 322 can extend into the chute opened on the lower surface of the frame 31 to prevent the slider 322 from rotating.

[0041] As an embodiment of the present invention, as Figure 4 shown, the wire laying assembly 33 further includes a telescopic rod and a rotating joint. The fixed end of the telescopic rod is connected to the upper surface of the mounting plate 331, and the telescopic end of the telescopic rod is connected to the rotating joint. The rotating joint can rotate around the vertical axis to adjust the horizontal orientation of the wire laying head 332. The telescopic rod and the rotating joint can be driven by manual operation, which is a conventional manual driving mechanism in the prior art and will not be described in detail here. In combination with the embodiments of the above-mentioned manual driving equipment, the continuous production in the emergency state is ensured.

[0042] As an embodiment of the present invention, the surface of the wire feeding roller in the wire feeding roller group 333 is provided with axially distributed raised stripes, and the raised stripes can be used to improve the traction force of the wire feeding roller group 333 on the glass fiber filaments, reducing the slipping phenomenon of the glass fiber filaments during the wire feeding process.

[0043] As an embodiment of the present invention, it further includes a mobile power supply (not shown in the drawings) for providing power. The mobile power supply is arranged on the side of the frame 31 and moves together with the frame, providing power for the equipment and also serving as an emergency power supply. The flexibility and emergency response ability of the equipment are improved, ensuring that the equipment can still operate normally in the case of power failure or unstable power supply, and improving the production stability.

[0044] The basic principles, main features and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
