Abstract
Description
Technical Field
[0001] This application relates to the field of fiberglass grating production, and more particularly to a continuous automated production line for molded fiberglass grating. Background Technology
[0002] In the industrial production sector, fiberglass grating, as an important building and industrial material, has been widely used in various industries such as chemical, construction, and environmental protection due to its lightweight, high strength, and corrosion resistance. With the continuous development of these industries, market demand for fiberglass grating is constantly increasing, requiring not only a significant increase in output but also more stringent standards for product quality and production efficiency. An efficient and stable fiberglass grating production line plays a crucial role in meeting market demands and enhancing the competitiveness of enterprises in the market.
[0003] Previously, the production of molded fiberglass grating primarily employed an intermittent production method. In this method, the molds were used individually. Workers manually placed resin slurry and chopped fibers into the molds, using a chopped fiber infusion method, making it impossible to use long fibers of uniform specifications. During the molding process, traditional molding techniques were relied upon to shape the resin slurry and chopped fibers. Demolding was performed manually or with simple mechanical devices, removing each mold piece individually. Cutting and material collection were also done manually or with semi-automated equipment, sequentially processing each product. Throughout the entire production process, each stage was relatively independent, lacking systematicity and continuity.
[0004] However, existing methods for producing molded fiberglass grating have significant drawbacks. Because only chopped fiber injection can be used, it's impossible to use long fibers of consistent specifications. This results in gratings with lower strength, which are difficult to meet engineering requirements. Furthermore, intermittent production and manual operation lead to low efficiency, making it difficult to meet large-scale production demands. The instability of manual operation also easily leads to inconsistent product quality, making it impossible to guarantee product consistency and stability. In addition, the lack of smooth coordination between different stages of the production process results in significant time waste and increased production costs. Summary of the Invention
[0005] In order to enable continuous production and improve the quality of FRP grating products by using long fibers, this application provides a continuous automated production line for molded FRP grating.
[0006] This application provides a continuous automated production line for molded fiberglass grating, employing the following technical solution: It includes a main frame and further includes: a mold running track, horizontally mounted on the main frame, with several molds slidably connected to the track, arranged sequentially in series along the sliding direction; a mold pushing device, located at the beginning of the track, for pushing the molds onto the track and driving them to slide; a demolding device, located at the end of the track, for demolding the molds from the formed fiberglass grating; each mold includes a base plate with side plates on both sides along the sliding direction, a module assembly between the side plates, and a demolding mechanism for ejecting the finished fiberglass grating from the mold; a high-precision fixed-length cutting device, located downstream of the demolding device, for slitting the finished fiberglass grating; and a fiberglass weaving system, located above the track and downstream of the pushing device, for pre-setting radial and weft fiberglass yarns within the mold during operation.

[0068] The following is in conjunction with the appendix Figure 1-23 This application will be described in further detail.
[0069] The continuous automated production line for molded fiberglass grating provided in this application embodiment refers to... Figure 1 The system includes a main frame 1, a mold running track 11, a mold pushing device 2, a demolding device 3, a surface treatment system 4, a high-precision fixed-length cutting device 5, a material feeding device 6, a mold circulation system 7, a glass fiber weaving system 8, and an injection device 9. The mold running track 11 is horizontally positioned on the main frame 1. Several molds 31 slide and connect on the mold running track 11 and are arranged in series. The number of molds 31 is determined by the length of the mold running track 11. The mold pushing device 2 is located at the beginning of the mold running track 11, and the demolding device 3 is located at the end of the mold running track 11. The surface treatment system 4 is... Downstream of the demolding device 3, a high-precision fixed-length cutting device 5 is used to clean the resin waste sheets and burrs on the top of the fiberglass grating. The high-precision fixed-length cutting device 5 is located downstream of the surface treatment system 4, and the unloading device 6 is located downstream of the high-precision fixed-length cutting device 5. The mold circulation system 7 is used to send the demolded mold 31 back to the mold pushing device 2. The fiberglass weaving system 8 is located above the mold running track 11 and downstream of the mold pushing device 2. The glue injection device 9 is located outside the main line frame 1. This arrangement enables the various parts of the production line to cooperate in an orderly manner, realizing the continuous automated production of molded fiberglass gratings and improving production efficiency and product quality.
[0070] Reference Figure 2 The mold running track 11 is horizontally set on the main frame 1, providing a stable path for the sliding of the mold 31. To reduce the friction force on the mold 31 during the sliding process, several guide wheels 111 are rotatably connected on the mold running track 11. The guide wheels 111 include two sets, one set horizontally and one set vertically. The vertically set guide wheels 111 are used to support the mold 31, and the horizontally set guide wheels 111 are used to limit the sliding direction of the mold 31, preventing the mold 31 from sliding left and right on the mold running track 11, and ensuring that adjacent molds 31 can always remain aligned and slide along the length direction of the mold running track 11.
[0071] Reference Figure 1 as well as Figure 3The mold 31 includes a base plate 311, with side plates 312 on both sides of the base plate 311. The side plates 312 are located on both sides of the mold 31 in the sliding direction. The base plate 311 and the side plates 312 enclose a molding cavity. A module assembly is provided on the base plate 311 within the molding cavity. The module assembly includes several modules 313 arranged in an array within the molding cavity. The molds 31 located on the mold running track 11 are arranged sequentially and connected end to end. The end faces of two adjacent molds 31 abut against each other. The molding cavities of the molds 31 located on the mold running track 11 are interconnected, thereby enabling the continuous forming of the fiberglass grating. Continuing production, the already formed fiberglass grating near the rear of the mold running track 11 prevents the resin mixture that has not yet formed at the front end of the mold running track 11 from flowing out of the front end of the mold 31. Furthermore, the resin slurry is added at the beginning of the mold running track 11. Since new molds 31 are continuously added to the mold running track 11, after the molds 31 abut each other, as long as the flow rate of the resin mixture is controlled, even if resin slurry is filled into the mold 31, the resin slurry will not flow out from the rear end of the mold 31, and the resin slurry poured into the mold 31 can be retained within the mold 31. In addition, to prevent raw materials from flowing out from the gap between the two molds 31, a sealing strip is embedded on the end face of the base plate 311. After adjacent molds 31 abut each other, the sealing strips on the adjacent molds 31 abut each other, improving the sealing performance between the molds 31.
[0072] To facilitate the separation of the mold 31 from the finished fiberglass grating, a demolding mechanism 32 is also provided on the base plate 311. The demolding mechanism 32 is located on the bottom surface of the base plate 311 and includes three ejector plates 321 located below the base plate 311. The three ejector plates 321 are located in the same plane and parallel to the base plate 311. The three ejector plates 321 are all slidably connected to the base plate 311 through guide pillars and sleeves. The guide pillars are set perpendicular to the base plate 311. Several ejector pins 322 are fixedly connected to the ejector plates 321. One end of the ejector pin 322 is fixed to the ejector plate 321. A through hole is provided on the base plate 311 for the other end of the ejector pin 322 to slide. The through hole is located in the gap between the modules 313 and its size matches that of the ejector pin 322, so as to achieve a sealed connection between the ejector pin 322 and the base plate 311.
[0073] Under normal conditions, the ejector plate 321 is away from the base plate 311. At this time, the top surface of the ejector pin 322 is flush with the top surface of the base plate 311. The ejector pin 322 will not affect the molding of the fiberglass grating. When it is necessary to demold the molded fiberglass grating in the mold 31, it is only necessary to drive the ejector plate 321 to slide towards the base plate 311, and the ejector pin 322 can push the fiberglass grating out of the mold 31.
[0074] Reference Figure 4A mold pushing device 2 is provided at the starting end of the mold running track 11. The mold pushing device 2 is used to push the mold 31 to the mold running track 11 and drive the mold 31 to slide intermittently on the mold running track 11 in accordance with the needs of the glass fiber weaving system 8.
[0075] Reference Figure 4 as well as Figure 5 The mold pushing device 2 includes a mold pushing frame 21, which is fixedly installed at the front end of the main frame 1. The mold pushing frame 21 is U-shaped. A mold pushing seat 22 is slidably connected to the mold pushing frame 21 along the length of the mold running track 11. The mold pushing seat 22 is slidably connected to the mold pushing frame 21 via a linear guide rail 315. Two mold pushing seats 22 are arranged in a group on both sides of the mold running track 11. The mold pushing seats 22 in the same group are located on the same horizontal plane, and push blocks 23 are provided opposite to each other on the two mold pushing seats 22. The push blocks 23 are rotatably mounted on the mold pushing seat 22. One group of push blocks 23 rotates horizontally. Push plates 314 are fixedly connected to both sides of the mold 31. The push plates 314 are fixed to the outer surface of the side plate 312. The mold pushing frame 21 is also provided with a mechanism to drive the mold pushing seat 22 to slide. The die-pushing drive mechanism can be a hydraulic cylinder, an electric screw, or a chain drive. In this embodiment, the die-pushing drive mechanism includes a die-pushing screw 24, which is rotatably mounted on the die-pushing frame 21. The die-pushing screw 24 is arranged along the length of the die running track 11. The die-pushing seat 22 is threadedly connected to the die-pushing screw 24. The die-pushing screw 24 is driven by a motor fixedly mounted on the die-pushing frame 21. When the die-pushing seat 22 slides toward the die running track 11, the push block 23 rotates to the position of abutting against the push plate 314, thereby pushing the die 31 to slide on the die running track 11. When the die-pushing seat 22 slides away from the die running track 11, the push block 23 abuts against the push plate 314 and rotates to the outside of the push plate 314, and the die-pushing seat 22 can then return to its initial position.
[0076] A torsion spring is provided on the ejector base 22 to drive the ejector block 23 to return to a position perpendicular to the ejector base 22. The torsion spring is sleeved on the rotating shaft of the ejector block 23, with one end of the torsion spring fixed to the ejector base 22 and the other end fixed to the ejector block 23. To facilitate the rotation of the ejector block 23, inclined surfaces are provided on the opposite sides of the ejector plate 314 and the ejector block 23 when the ejector block 23 retracts. When the ejector block 23 contacts the ejector plate 314, the contact area is increased to ensure that the ejector block 23 can rotate smoothly to the outside of the ejector plate 314.
[0077] To improve the conveying efficiency of the mold 31, two sets of push mold seats 22 are provided on the push mold frame 21. One set is located on the inner side of the push mold frame 21, and the other set is located on the top surface of the push mold frame 21. The push mold seats 22 in the same set are symmetrically arranged on both sides of the mold 31. The push blocks 23 on the push mold seats 22 located on the side of the push mold frame 21 rotate horizontally, while the push blocks 23 on the push mold seats 22 located on the top surface of the push mold frame 21 rotate vertically. Both sets of push mold seats 22 are driven to slide by independent push mold drive mechanisms, and the two sets of push mold seats 22 slide independently without interfering with each other. Correspondingly, the size of the push plate 314 is also set to correspond to the push seats, ensuring that the push blocks 23 on both sides and the top of the push mold frame 21 can contact the push plate 314 after sliding.
[0078] When pushing mold 31, the mold circulation system 7 first transports a single mold 31 into the mold pushing frame 21. The mold pushing base 22 is located on both sides of the mold 31, and the mold 31 is flush with the mold running track 11. Then, the mold pushing drive mechanism drives one set of mold pushing bases 22 to slide towards the mold running track 11. The push block 23 on the mold pushing base 22 abuts against the push plate 314, pushing the mold 31 to slide towards the mold running track 11, driving the mold 31 to slide intermittently and continuously on the mold running track 11; the current mold 31 is completely pushed into the mold running track 11. After the mold 31 is on the running track 11, the mold circulation system 7 continues to transport the next mold 31 to the mold pusher frame 21. Another set of pusher seats 22 drives the second mold 31 to continue sliding towards the mold running track 11. When the second mold 31 comes into contact with the front mold 31, the first set of pusher seats 22 can return to the initial position, waiting for the subsequent mold 31 to be added to the mold pusher frame 21. The two sets of pusher seats 22 cycle back and forth, so that the mold 31 can be continuously pushed on the mold running track 11, ensuring the continuity of the subsequent production process.
[0079] Reference Figure 6 When the mold 31 enters the mold running track 11, the glue injection device 9 first fills the mold 31 with the mixed resin slurry.
[0080] The dispensing device 9 includes a feeding frame 91, which is located on one side of the main line frame 1. The feeding frame 91 is equipped with a raw material storage tank 92, a curing agent storage tank 93, a mixing tank 94, and a temporary storage tank 95. The raw material storage tank 92 stores resin raw materials and has a temperature control function to prevent the resin raw materials from solidifying. The curing agent storage tank 93 stores curing agent. The bottom of the raw material storage tank 92 is connected to a delivery pump 921 via a pipe. The delivery pump 921 is used to deliver the resin from the raw material storage tank 92 into the mixing tank 94. The bottom of the curing agent storage tank 93 is connected to an addition pump 931 via a pipe. The addition pump 931 is used to deliver the curing agent from the curing agent storage tank 93 into the storage tank. A discharge control valve 941 is connected to the bottom of the mixing tank 94. The temporary storage tank 95 is located below the mixing tank 94, with its top opening facing the discharge control valve 941. Opening the discharge control valve... 941, the mixture in the mixing tank 94 can flow into the temporary storage tank 95. The temporary storage tank 95 is connected to the glue supply pump 951 through the pipe. The glue supply pump 951 is used to transport the raw materials in the temporary storage tank 95 to the mold 31. The output end of the glue supply pump 951 extends through the pipe to the mold 31 located on the mold running track 11. When the glue supply pump 951 is turned on, the mixture in the temporary storage tank 95 can be transported to the mold 31. The conveying pump 921, the adding pump 931 and the glue supply pump 951 can be centrifugal pumps or gear pumps.
[0081] To facilitate control of the mixing ratio of resin raw materials and curing agent, weighing sensors 96 are installed at the connection points of the raw material storage tank 92, curing agent storage tank 93, mixing tank 94, and temporary storage tank 95 with the feeding frame 91. These weighing sensors 96 allow for precise control of the weight of the resin raw materials and curing agent input into the mixing tanks, achieving accurate control of the mixing ratio. Furthermore, the weight of the mixture delivered to the mold 31 can be precisely controlled according to production needs, ensuring product quality. During production, mixing can be performed in real time; only the required amount of mixture is mixed, avoiding material waste.
[0082] Reference Figure 7 After the mold 31 is injected with glue by the glue injection device 9, it can enter the glass fiber weaving system 8 under the push of the mold pushing device 2. During the operation of the mold 31, radial glass fiber yarn is preset into the mold 31 and weft glass fiber yarn is preset simultaneously. Under the division of the module 313, the mold 31 forms staggered radial gaps and weft gaps. The radial glass fiber yarn is laid along the radial gaps, and the weft glass fiber yarn is laid along the weft gaps.
[0083] Reference Figure 8The fiberglass weaving system 8 includes a yarn frame 81 mounted on the main frame 1. The yarn frame 81 is equipped with several warp yarn laying devices 82 and weft yarn laying devices 83. The warp yarn laying devices 82 and weft yarn laying devices 83 are spaced apart along the length of the mold running track 11 and are all located above the mold running track 11. By setting multiple sets of warp yarn laying devices 82 and weft yarn laying devices 83, multiple layers of radial fiberglass yarn and weft fiberglass yarn can be laid according to product needs.
[0084] The weft yarn routing device 83 includes a weft yarn threading tube 831 that slides along the width direction of the mold running track 11. The yarn frame 81 is provided with a weft yarn driving mechanism that drives the weft yarn threading tube 831 to slide back and forth. The weft yarn driving mechanism includes a weft yarn seat 832 that is slidably disposed on the yarn frame 81. The weft yarn seat 832 slides along the width direction of the mold running track 11. A guide post is provided on the yarn frame 81. The weft yarn seat 832 is slidably connected to the yarn frame 81 through the guide post. A synchronous belt 833 is rotatably connected to the yarn frame 81. The weft yarn seat 832 is fixed to the synchronous belt 833. The yarn frame 81 is also provided with a weft yarn drive motor 834 for driving the synchronous belt 833 to rotate. The weft yarn drive motor 834 and the pulley of the synchronous belt 833 are connected by a coupling and a commutator. After the weft yarn drive motor 834 rotates, it can drive all the weft yarn seats in the weft yarn routing device 83 to slide back and forth synchronously.
[0085] The weft yarn threading tube 831 is fixedly mounted on the weft yarn fabric holder 832. The weft yarn threading tube 831 is vertically positioned, and its outlet is located inside the mold 31. The weft yarn threading tube 831 slides within the gap between the modules 313. The weft fiberglass yarn comes from the yarn roll on the yarn frame. After passing through the weft yarn threading tube 831, the weft fiberglass yarn is output from the outlet and laid out along the weft gap inside the mold 31. When the weft yarn threading tube 831 slides within the weft gap, the mold 31 stops sliding. When the weft yarn threading tube 831 slides to the end of the weft gap and contacts the side plate 312 of the mold 31, the mold 31 slides forward. When there is only one weft yarn threading tube 831, the sliding length of the mold 31 is the length of one module 313. At this time, the weft yarn threading tube 831 moves to the end of the weft gap of the adjacent unlaid weft glass fiber yarn. Then the weft yarn threading tube 831 slides to the other side of the mold 31. Repeat the above steps, and the weft glass fiber yarn can be continuously and S-shapedly laid in the mold 31.
[0086] The warp yarn routing device 82 includes several warp yarn threading tubes 822. A warp yarn beam 821 is fixedly connected to the yarn rack 81. The warp yarn beam 821 is arranged along the width direction of the mold running track 11. The warp yarn threading tubes 822 are fixed to the warp yarn beam 821 by fixing plates 823 and bolts. The warp yarn threading tubes 822 are arranged vertically and bent at the bottom towards the sliding direction of the mold 31. The yarn outlets of the warp yarn threading tubes 822 are all located inside the mold 31. The number of warp yarn threading tubes 822 corresponds to the number of radial gaps inside the mold 31. The radial glass fiber yarn passing through the warp yarn threading tubes 822 comes from the yarn roll on the yarn rack at one end and extends into the solidified fiberglass grating at the other end. Therefore, as the mold 31 slides forward, the radial glass fiber yarn will be automatically and continuously laid into the radial gaps under the pull of the mold 31.
[0087] Reference Figure 9 To improve the yarn distribution effect of multiple warp and weft yarns, a glass fiber compaction device 84 is provided on the yarn frame 81. The glass fiber compaction device 84 is used to compact the glass fiber yarn in the mold 31. The glass fiber compaction device 84 includes a radial yarn compaction mechanism and a weft yarn compaction mechanism. The radial yarn compaction mechanism includes a warp yarn compaction plate 841, which is fixedly connected to the yarn frame 81. The warp yarn compaction plate 841 is located between the warp yarn distribution device 82 and the weft yarn distribution device 83. The warp yarn compaction plate 841 is set on both sides of the mold 31 and its bottom is located in the radial gap between the two sides of the mold 31. It is used to compact the warp and weft yarns on both sides of the mold 31. The end of the warp yarn compaction plate 841 is provided with a guide arc surface to avoid scratching the warp and weft yarns. During the forward sliding of the mold 31, when the radial glass fiber yarns located on both sides of the mold 31 pass through the compaction plate, they are pressed and compacted by the bottom surface of the warp yarn compaction plate 841.
[0088] The weft pressing mechanism is located downstream of the weft yarn laying device 83. The weft pressing mechanism includes a weft pressing plate 842, which is arranged along the width direction of the mold 31. The length and thickness of the weft pressing plate match the weft gap size. The weft pressing plate 842 is slidably connected to the yarn frame 81 in the vertical direction through guide posts. A pressing cylinder 843 is fixedly connected to the yarn frame 81 to drive the weft pressing plate 842 to slide. Under the drive of the pressing cylinder 843, the weft pressing plate 842 slides toward the mold 31. The bottom of the weft pressing plate 842 extends into the weft gap and abuts against the weft glass fiber yarn. While pressing the weft glass fiber yarn, the radial glass fiber yarn can also be pressed.
[0089] Reference Figure 1After the radial and weft fiberglass yarns in the mold 31 are filled, the mold 31 continues to slide along the mold running track 11 under the push of the mold pushing device 2 and enters the heating system 12. The heating system 12 includes a resin heating and curing machine. The mold running track 11 passes through the resin heating and curing machine. The resin heating and curing machine heats the mold 31 to promote the resin to accelerate the curing reaction. The resin heating and curing machine is existing technology and will not be described in detail here. After the mold 31 is output from the resin heating and curing machine, the resin inside the mold 31 is cured and formed into a fiberglass grating. At this time, the fiberglass grating is in a continuous state. After subsequent surface treatment and cutting, the finished fiberglass grating can be formed.
[0090] Reference Figure 10 After the mold 31 is output from the heating system 12 and cooled, the mold 31 and the formed fiberglass grating slide to the end of the mold running track 11. After the mold 31 is output from the mold running track 11, it enters the demolding device 3. The demolding device 3 is used to separate the mold 31 from the fiberglass grating in sequence.
[0091] Reference Figure 11 The demolding device 3 includes a demolding frame 33, which is placed on the ground and located at the end of the mold running track 11. A demolding moving frame 331 is slidably arranged on the demolding frame 33 along the sliding direction of the mold 31, and a demolding platform 332 is slidably arranged on the demolding moving frame 331 along the vertical direction. The demolding moving frame 331 and the demolding platform 332 can be slidably connected by guide rail 315 and slider to ensure the smoothness of their movement. In addition, the demolding frame 33 is provided with a second driving component for driving the demolding moving frame 331 to slide. The second driving component is a second cylinder 334. The second cylinder 334 is horizontally set and fixed on the demolding frame 33. The piston rod of the second cylinder 334 is connected to the demolding moving frame 331. The demolding moving frame 331 is provided with a third driving component for driving the demolding platform 332 to slide. The third driving component is a third cylinder 335. The third cylinder 335 is vertically set and fixed on the demolding moving frame 331. The piston rod of the third cylinder 335 is connected to the demolding platform 332.
[0092] The demolding platform 332 is provided with a guide groove 3321. A guide rail 315, which mates with the guide groove 3321, is provided on the base plate 311 of the mold 31. The guide rail 315 and the guide groove 3321 have a T-shaped cross-section and are arranged along the sliding direction of the mold 31. Side pressure plates 3322 are provided on both sides of the demolding platform 332. The side pressure plates 3322 are symmetrical and arranged in an inverted L-shape. When the mold 31 is pushed above the demolding platform 332 by the mold pushing device 2, the side pressure plates 3322 are positioned above the side plates 312. When the guide rail 315 slides into the guide groove 3321, a first driving member is provided on the demolding platform 332 for driving the ejector plate 321 to slide toward the bottom plate 311. The first driving member includes a top plate 3323 slidably disposed on the demolding platform 332. The top plate 3323 is parallel to the ejector plate 321. The top plate 3323 is slidably connected to the demolding platform 332 through guide pillars. The top plate 3323 slides vertically. A demolding cylinder 333 is fixedly connected to the bottom surface of the demolding platform 332. The piston rod of the demolding cylinder 333 passes through the demolding platform 332 and is fixedly connected to the top plate 3323.
[0093] When demolding is required, the second cylinder 334 and the third cylinder 335 work together to drive the demolding platform 332 to move to the front end of the mold 31. Then, the demolding platform 332 slides toward the mold 31, and the guide rail 315 is embedded in the guide groove 3321. At this time, the side pressure plate 3322 is located above the side plate 312. Then, the demolding cylinder 333 drives the top plate 3323 to slide upward. The top plate 3323 abuts against the ejector plate 321 and drives the ejector pin 322 to slide upward, pushing the formed fiberglass grating out of the mold 31. At the same time, the third cylinder 335 drives the demolding platform 332 to move downward as a whole, moving the mold 31 away from the demolded fiberglass grating, completing the demolding operation. Finally, after pushing the mold 31 on the demolding platform 332 to the lower track 71, the second cylinder 334 and the third cylinder 335 drive the push platform to move in front of the mold 31 that has not been demolded. The above steps are repeated to realize the demolding operation of the mold 31 on the mold running track 11 in sequence.
[0094] Reference Figure 12 When the mold 31 is output from the demolding platform 332, it enters the mold circulation system 7. The mold circulation system 7 is used to transport the mold 31 output from the demolding device 3 to the mold pushing device 2.
[0095] The mold circulation system 7 includes a lower track 71 located below the mold running track 11. The lower track 71 is fixedly mounted on the main frame 1 and is parallel to the mold running track 11. To facilitate the sliding of the mold 31 on the demolding platform 332 onto the lower track 71, a push cylinder 336 is fixedly connected to the mold 31 moving frame. The piston rod of the push cylinder 336 is arranged along the length of the lower track 71. The push cylinder 336 is located on the side of the mold 31 moving frame away from the lower track 71, and the piston rod of the push cylinder 336 faces the lower track 71. A push plate 3361 is connected to the piston rod of the push cylinder 336. When the demolding platform 332 slides to the lowest point under the drive of the third cylinder 335, the bottom surface of the mold 31 is flush with the lower track 71. At this time, the piston rod of the push cylinder 336 extends, and the push plate 3361 pushes the mold 31 on the demolding platform 332 onto the lower track 71.
[0096] A return drive component is provided on the lower track 71 to drive the mold 31 to slide toward the mold pushing device 2. The return drive component includes several mold return chains 72. The sprockets of the mold return chains 72 are rotatably arranged on the lower track 71. The several mold return chains 72 are arranged sequentially along the length direction of the lower track 71. When the mold 31 is pushed onto the lower track 71, the bottom of the mold 31 abuts against the top of the mold return chain 72. After the mold return chain 72 rotates, it can drive the mold 31 to slide along the length direction of the lower track 71 toward the mold pushing mechanism 74.
[0097] Since the ejector plate 321 needs to slide upward during demolding to push the formed fiberglass grating out of the mold 31, the ejector pins 322 and ejector plate 321 also need to be reset after demolding. To facilitate the reset of ejector pins 322 and ejector plate 321, an ejector reset device is provided in the mold circulation system 7. The ejector reset device includes an ejector pressure plate 13 and pressure strips 131. The ejector pressure plate 13 is set on the main frame 1 near the demolding device 3. The ejector pressure plate 13 is horizontally set between the lower track 71 and the mold running track 11. The ejector pressure plate 13 and the main frame 1 are slidably connected through guide pillars and sleeves. Several pressure strips 131 are provided on the bottom surface of the ejector pressure plate 13 along the length of the lower track 71. The pressure strips 131 are correspondingly set with the ejector pins 322. When the mold 31 on the lower track 71 slides to below the ejector pressure plate 13, the ejector pressure plate 13 slides toward the mold 31, and the pressure strips 131 abut against the ejector pins 322, pressing the top of the ejector pins 322 to be flush with the bottom surface of the mold 31, thereby realizing the reset of the ejector pins 322 and ejector plate 321.
[0098] Reference Figure 12 as well as Figure 13To facilitate the sliding of the ejector plate 13, the ejector reset device also includes a drive block 34 mounted on the demolding frame 33. The drive block 34 is located below the demolding moving frame 331. There are two drive blocks 34, which are respectively mounted on both sides of the demolding frame 33. The drive blocks 34 are slidably connected to the demolding frame 33 and the sliding direction is parallel to the sliding direction of the demolding moving frame 331. The two drive blocks 34 are connected to both sides of the ejector plate 13 by pull ropes 132. A reversing wheel is rotatably connected to the demolding frame 33 and the main frame 1. The end of the pull rope 132 passes around the reversing wheel and is fixed to the bottom surface of the ejector plate 13. When the drive block 34 slides toward the end away from the lower track 71, the ejector plate 13 slides downward under the pull of the pull rope 132. The bottom of the demolding moving frame 331 is fixedly connected with two levers 35, which are corresponding to the drive block 34. A locking tongue 341 is slidably connected to the drive block 34. The locking tongue 341 is set vertically to the levers 35 and is slidably connected to the drive block 34. The locking tongue 341 is embedded in the end face of the drive block 34. The end of the locking tongue 341 that extends out of the drive block 34 is provided with a guide slope. The guide slope is set towards the second cylinder 334. Inside the drive block 34, there is an ejection spring that drives the locking tongue 341 to stay in the extended state. When the levers 35 slide with the demolding moving frame 331 to near the lower track 71, the end of the levers 35 abuts against the guide slope, and the locking tongue 341 is pressed into the drive block 34. The levers 35 finally slide between the locking tongue 341 and the lower track 71.
[0099] When the mold 31 on the demolding platform 332 is pushed onto the lower track 71, the demolding moving frame 331 slides toward the end away from the lower track 71. After the lever 35 abuts against the locking tongue 341, it drives the driving block 34 away from the lower track 71, thereby driving the ejector plate 13 to slide downward. When the demolding moving frame 331 slides to the farthest end, the pressure bar 131 below the ejector plate 13 abuts against the ejector 322, driving the ejector 322 to reset. To facilitate the release of the contact between the lever 35 and the locking tongue 341, a reset lever 36 is fixedly connected to the demolding frame 33 below the demolding moving frame 331. The reset lever 36 is set along the sliding direction of the demolding moving frame 331 and is located on the side of the drive block 34 away from the lower track 71. A wedge-shaped hole 3411 is provided on the locking tongue 341 facing the reset lever 36. When the ejector pin 322 resets, the reset lever 36 passes through the waist-shaped hole opened on the drive block 34 and inserts into the wedge-shaped hole 3411. The reset lever 36 drives the locking tongue 341 to slide towards the inside of the drive block 34, releasing the contact between the locking tongue 341 and the lever 35.
[0100] To facilitate the upward reset of the ejector plate 13, several reset springs 133 are fixedly connected to the main frame 1. One end of the reset spring 133 is fixed to the main frame 1, and the other end is fixed to the top surface of the ejector plate 13. After the locking tongue 341 retracts into the drive block 34, the reset spring 133 pulls the ejector plate 13 to slide upward, thereby driving the drive block 34 to slide to one end near the lower track 71, waiting for the next mold 31 to perform the ejector 322 reset operation.
[0101] Reference Figure 14 The lower track 71 is provided with a lifting mechanism 73 at one end away from the demolding device 3. The lower track 71 is provided with a pushing mechanism 74 for pushing the mold 31 to the lifting mechanism 73. When the mold 31 is transported to the end of the lower track 71, the pushing mechanism 74 pushes the mold 31 from the lower track 71 to the lifting mechanism 73. The lifting mechanism 73 raises the mold 31 into the mold pushing device 2 and makes it flush with the mold running track 11.
[0102] Reference Figure 15 The lifting mechanism 73 includes a lifting frame 731, which is placed on the ground and located at the end of the lower track 71. A lifting platform 732 is slidably connected to the lifting frame 731. The lifting platform 732 is slidably connected to the lifting frame 731 through guide columns and sliding sleeves. The lifting platform 732 is horizontally arranged. The lifting frame 731 is provided with a lifting drive component 733, which is used to drive the lifting platform 732 to slide to a position flush with the mold running track 11 or the lower track 71. The lifting drive component 733 can be a hydraulic cylinder or an electric lead screw. To facilitate the positioning of the mold 31, a limiting plate 734 is provided on the side of the lifting platform 732 away from the lower track 71. The limiting plate 734 is set vertically. When the mold 31 is pushed by the mold pushing mechanism 74, the mold 31 slides to abut against the limiting plate 734 and then stops sliding. The limiting plate 734 can prevent the mold 31 from sliding off the lifting platform 732 and improve the stability of the mold 31 during the transfer process.
[0103] Reference Figure 16The mold ejection mechanism 74 includes a mold return main frame 741 fixedly connected to the mold running track 11. The mold return main frame 741 is located above the lower track 71 and close to the lifting mechanism 73. A mold return sub-frame 742 is slidably connected to the mold return main frame 741 via a linear guide rail. The sliding direction of the mold return sub-frame 742 is parallel to the sliding direction of the mold 31. Swing arms 743 are connected to both sides of the mold 31 on the mold return sub-frame 742. The swing arms 743 are L-shaped and rotatably connected to the mold return sub-frame 742. The rotation direction of the swing arms 743 is tangential to the sliding direction of the mold return sub-frame 742. The swing arms 743 are located away from the mold 31. One end of the mold return sub-frame 742 is rotatably connected to an auxiliary wheel 744. The axis of rotation of the auxiliary wheel 744 is parallel to the axis of rotation of the swing arm 743. The mold return sub-frame 742 is provided with a relief groove 7421 for the swing arm 743 to be inserted when the swing arm 743 retracts. After the swing arm 743 slides with the mold return sub-frame 742, it can abut against the push plates 314 on both sides of the mold 31. The mold return main frame 741 is provided with a push mold cylinder 745 that drives the mold return sub-frame 742 to slide back and forth. The push mold cylinder 745 is arranged along the sliding direction of the mold 31 and fixed to the mold return main frame 741. The piston rod of the push mold cylinder 745 is connected to the mold return sub-frame 742.
[0104] When the mold 31 slides to the end of the lower track 71, the swing arm 743 is located on the side of the push plate 314 away from the lifting platform 732. The push cylinder 745 drives the return mold sub-frame 742 to slide towards the lifting platform 732. After the swing arm 743 abuts against the push plate 314, the swing arm 743 rotates to the position where it abuts against the return mold sub-frame 742 and can no longer rotate. The return mold sub-frame 742 pushes the mold 31 to slide and pushes the mold 31 onto the lifting platform 732. Then the push cylinder 745 retracts. When the swing arm 743 touches the push plate 314 on the next mold 31, the swing arm 743 will rotate upward under the guidance of the auxiliary wheel 744. Since a clearance groove 7421 is provided on the return mold sub-frame 742, the swing arm 743 will rotate above the push plate 314. After the swing arm 743 passes the push plate 314, the swing arm 743 resets under its own weight, and then the next mold 31 can be pushed.
[0105] With the cooperation of the lifting mechanism 73 and the pushing mechanism 74, the mold 31 transported to the end of the lower track 71 can be continuously transported into the pushing frame 21. Under the push of the mold pushing device 2, the mold 31 is transported to the mold running track 11 and continues to carry out production operations, thereby realizing the recycling of the mold 31.
[0106] Reference Figure 17To further improve product quality, after demolding, the fiberglass grating needs to undergo post-processing. A surface treatment system 4 is installed downstream of the demolding device 3. The surface treatment system 4 is used to clean the resin waste sheets and burrs on the top of the fiberglass grating. After processing, the fiberglass grating can be conveyed to the high-precision fixed-length cutting device 5 for slitting.
[0107] Reference Figure 18 as well as Figure 19 The surface treatment system 4 includes a post-treatment frame 41, which is placed on the ground and located downstream of the demolding frame 33. The post-treatment frame 41 is equipped with a resin sheet removal device and a polishing device. The resin sheet removal device includes a resin sheet pressure plate 42 slidably mounted on the post-treatment frame 41. The resin sheet pressure plate 42 is vertically slidably connected to the post-treatment frame 41 via guide posts and guide sleeves. The resin sheet pressure plate 42 is horizontally positioned, and a plurality of pressure blocks 421 are arranged on its bottom surface. The pressure blocks 421 are arrayed on the bottom surface of the resin sheet pressure plate 42, and their positions correspond to the grid holes of the fiberglass grating. The pressure blocks 421 are used to press the resin waste sheets on the fiberglass grating. The post-treatment frame 41 is equipped with a pressing cylinder 43 for driving the resin sheet pressure plate 42 to slide. The pressing cylinder 43 is fixedly mounted on the post-treatment frame 41 and is vertically positioned. The piston rod of the pressing cylinder 43 is connected to the resin sheet pressure plate 42. Several guide rollers 44 are rotatably connected on the post-processing frame 41 below the resin sheet pressure plate 42. The guide rollers 44 are used to support the fiberglass grating.
[0108] When the fiberglass grating slides to below the resin sheet pressure plate 42, the pressure cylinder 43 drives the resin sheet pressure plate 42 to slide downwards, and the pressure block 421 presses down the waste sheet covering the top of the fiberglass grating hole, and the waste sheet falls from the bottom of the grating hole, thus completing the cleaning of the resin waste sheet.
[0109] The polishing device is located downstream of the resin sheet removal device. The polishing device includes a polishing seat 45 slidably mounted on the post-processing frame 41. Two guide rods 46 are fixedly connected to the post-processing frame 41. The two guide rods 46 are horizontally arranged and arranged along the width direction of the fiberglass grating. The polishing seat 45 is slidably connected to the guide rods 46. The post-processing frame 41 is provided with a polishing drive component that drives the polishing seat 45 to slide back and forth. The polishing drive component includes a chain rotatably mounted on the post-processing frame 41. The polishing seat 45 is fixedly connected to the chain. The post-processing frame 41 is provided with a travel motor 47 that drives the chain to rotate. The output shaft of the travel motor 47 is connected to the sprocket of the chain through a reducer.
[0110] A grinding motor 451 is fixedly connected to the grinding base 45. The grinding motor 451 is vertically arranged. A mounting plate 452 is rotatably connected to the grinding base 45. The output shaft of the grinding motor 451 is fixed to the rotating shaft of the mounting plate 452. The top of the grinding wheel 454 is slidably connected to the mounting plate 452 through a telescopic rod 455. The length direction of the telescopic rod 455 is parallel to the rotating shaft of the mounting plate 452. The rotating shaft of the grinding wheel 454 is coaxial with the rotating shaft of the mounting plate 452. A retaining spring 453 is also sleeved on the telescopic rod 455. One end of the retaining spring 453 abuts against the mounting plate 452, and the other end abuts against the grinding wheel 454. The retaining spring 453 drives the grinding wheel 454 to always abut against the top surface of the fiberglass grating.
[0111] When the fiberglass grating slides under the grinding seat 45, the traveling motor 47 drives the grinding seat 45 to slide back and forth, and the grinding motor 451 drives the grinding wheel 454 to rotate. The grinding wheel 454 grinds the top surface of the fiberglass grating. After the fiberglass grating is ground, it enters the high-precision fixed-length cutting device 5 for slitting. According to customer needs, the continuous fiberglass grating is cut into the required length.
[0112] Reference Figure 20 The high-precision fixed-length cutting device 5 includes a cutting frame 51 located downstream of the surface treatment system 4. The cutting frame 51 is placed on the ground and located downstream of the post-processing frame 41. A cutting platform 52 is slidably connected to the cutting frame 51. The cutting platform 52 is slidably connected to the cutting frame 51 via guide rails. The sliding direction of the cutting platform 52 is parallel to the sliding direction of the fiberglass grating. A positioning device for fixing the fiberglass grating to the cutting platform 52 is provided on the cutting platform 52. The positioning device includes a positioning frame 53. A positioning plate 54 is fixedly installed on the cutting platform 52 and is slidably connected to the positioning frame 53 in the vertical direction via guide columns and guide sleeves. The positioning plate 54 is horizontally set, and several positioning blocks 541 are fixedly connected to the bottom surface of the positioning plate 54. The positioning blocks 541 are set to correspond to the grid holes of the fiberglass grating. The positioning frame 53 is equipped with a positioning cylinder 55 for driving the positioning plate 54 to slide. The positioning cylinder 55 is fixed on the positioning frame 53 and is vertically set. The piston rod of the positioning cylinder 55 is connected to the positioning plate 54.
[0113] Reference Figure 21A cutting fixing beam 56 is fixedly connected to the cutting platform 52 along the width direction of the fiberglass grating. A cutting seat 57 is slidably connected to the cutting fixing beam 56. The cutting seat 57 is driven by a cutting drive component to slide back and forth. The cutting drive component includes a rack 561 fixedly mounted on the cutting fixing beam 56. A gear that meshes with the rack 561 is rotatably connected to the cutting seat 57. A cutting drive motor 571 that drives the gear to rotate is also fixedly connected to the cutting seat 57. The cutting drive motor 571 rotates in both directions, thereby realizing the reciprocating sliding of the cutting seat 57 on the cutting fixing beam 56. Two saw blades 572 are rotatably connected to the cutting seat 57. The two saw blades 572 are spaced apart and staggered. The length of the interval between the two saw blades 572 is equal to the length of the gap in the fiberglass grating. After cutting, the cut at the end of the fiberglass grating is a complete plane, which does not require secondary grinding. To facilitate the rotation of the saw blade 572, two cutting motors 573 are provided on the cutting seat 57, and the output shaft of the cutting motor 573 is connected to the rotating shaft of the corresponding saw blade 572.
[0114] To facilitate control of the cutting length, a rotary cylinder 58 is fixedly connected to the front of the cutting platform 52. The rotary cylinder 58 is slidably connected to the positioning frame 53. A stop block 581 is connected to the piston rod of the rotary cylinder 58. The rotation plane of the stop block 581 is perpendicular to the sliding direction of the fiberglass grating. A pressure sensor is installed on the stop block 581. When the fiberglass grating slides to abut against the stop block 581, the extension length of the fiberglass grating is the required length of the finished product. Subsequently, the pressure sensor transmits a signal to control the positioning cylinder 55 to drive the positioning plate 54 to press down. The fiberglass grating is fixed on the positioning frame 53, and the rotary cylinder 58 drives the stop block 581 to rotate below the fiberglass grating without affecting the forward sliding of the cut fiberglass grating. Then, the cutting drive motor 571 and the cutting motor 573 are driven, and the saw blade 572 slides along the width direction of the fiberglass grating to complete the cutting operation of the fiberglass grating. While the saw blade 572 is cutting, since the positioning block 541 is embedded in the grating hole of the fiberglass grating, even if the fiberglass grating slides forward continuously, the cutting platform 52 will slide synchronously with the fiberglass grating.
[0115] A reset cylinder 59 is also fixedly connected to the cutting frame 51. The reset cylinder 59 is set along the sliding direction of the cutting platform 52 and is located below the cutting platform 52. The piston rod of the reset cylinder 59 is connected to the cutting platform 52. After the fiberglass grating is cut, the positioning cylinder 55 drives the positioning plate 54 to slide upward, releasing the fiberglass grating from the cutting platform 52. Then, the reset cylinder 59 drives the cutting platform 52 and the rotating cylinder 58 to slide to the initial position, realizing the reset of the cutting platform 52, preparing for the next cut. This cycle repeats to realize the continuous cutting operation of the fiberglass grating.
[0116] After the fiberglass grating is cut, the finished fiberglass grating enters the feeding device 6, which is used to collect and stack the fiberglass grating.
[0117] Reference Figure 22 as well as Figure 23 The unloading device 6 includes a receiving rack 62 located downstream of the cutting device. A product stacking platform 61 is provided on one side of the receiving rack 62 for stacking finished fiberglass gratings. An extension rack 621 is fixedly connected to the receiving rack 62, perpendicular to it. One end of the extension rack 621 is fixed to the receiving rack 62, and the other end extends above the product stacking platform 61. A transfer rack 63 is slidably connected to the extension rack 621 via a linear guide rail 315. A drive mechanism is provided on the extension rack 621. The material transfer frame 63 has a sliding material transfer drive component, which includes a chain rotatably mounted on the extension frame 621 and a material transfer motor 64 fixed on the extension frame 621. The material transfer frame 63 is fixedly connected to the chain. After the material transfer motor 64 rotates, it drives the chain to move, thereby causing the material transfer frame 63 to slide back and forth on the extension frame 621. A material receiving gripper 631 is rotatably connected to the material transfer frame 63. The material transfer frame 63 is also equipped with a material receiving cylinder 632 that drives the material receiving gripper 631 to rotate. One end of the material receiving cylinder is rotatably connected to the material transfer frame 63, and the other end is rotatably connected to the material receiving gripper 631.
[0118] A take-up roller 65 is rotatably connected to the take-up rack 62. The rotation direction of the take-up roller 65 is tangential to the sliding direction of the fiberglass grating. There are several take-up rollers 65 arranged sequentially along the length of the take-up rack 62. The take-up rack 62 is equipped with a take-up drive component that drives the take-up rollers 65 to rotate. The take-up drive component includes several chains. Adjacent take-up rollers 65 are connected by chain drive. One of the take-up rollers 65 is connected to a motor. The take-up roller 65 rotates under the drive of the motor, causing the fiberglass grating located on the take-up roller 65 to slide toward the extension rack 621. When the fiberglass grating slides to below the extension rack 621, the end of the fiberglass grating abuts against the take-up rack 62, and the fiberglass grating stops sliding.
[0119] Reference Figure 20The receiving rack 62 is equipped with a lifting drive for lifting the fiberglass grating below the extension rack 621 into the receiving gripper 631. The lifting drive includes an electric scissor lift 66, which is placed on the ground and located below the receiving roller 65 and the extension rack 621. Several support columns 661 are provided on the top surface of the lift 66. When the fiberglass grating slides to below the extension rack 621, the lift 66 slides upward, and the support columns 661 abut against the fiberglass grating. The lift 66 lifts the fiberglass grating into the receiving gripper 631. Then, the receiving cylinder 632 drives the receiving gripper 631 to rotate, and the receiving gripper 631 clamps the two sides of the fiberglass grating. The transfer rack 63 drives the fiberglass grating to slide toward the product stacking platform 61. When the transfer rack 63 slides above the product stacking platform 61, the receiving gripper 631 resets, and the fiberglass grating can be placed on the product stacking platform 61.
[0120] To improve the stacking effect of FRP grating, the product receiving platform can be automatically raised and lowered according to the stacking height of FRP grating, thereby reducing the falling distance of FRP grating on the transfer rack 63. The above effect can be achieved by using a gravity-sensing lift 66, which is existing technology and will not be elaborated on here.
[0121] The implementation principle of this embodiment is as follows: This production line achieves continuous automated production of molded fiberglass grating through the coordinated operation of various devices. The mold pushing device 2 sequentially pushes the molds 31 to the mold running track 11. The glue injection device 9 injects resin mixture slurry, and the fiberglass weaving system 8 lays fiberglass yarn inside the mold 31. As the mold 31 moves along the mold running track 11, it passes through the heating system 12, accelerating the curing and molding of the resin within the mold 31. The demolding device 3 separates the finished fiberglass grating from the mold 31. The surface treatment system 4 cleans the resin waste sheets and burrs from the top of the fiberglass grating. The high-precision fixed-length cutting device 5 cuts the finished product, and the unloading device 6 collects and stacks it. The mold recycling system 7 returns the demolded molds 31 to the mold pushing device 2, enabling the recycling of the molds 31. The entire production process reduces manual operation, improves production efficiency and product quality, reduces production costs, and solves many problems existing in current production methods.
[0122] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
