before the automatic production equipment is installed, grooving is needed to be carried out on each of the transverse and longitudinal frames of the original die, and the automatic production equipment has the advantages that after one wiring period is finished, the elastic wiring tube can enter the grooving, so that space is reserved for the wiring device in the other direction to work, the effect of compacting yarns is achieved, and the elastic wiring tube cannot be taken out of the die when being used by the unlimited pipe in the other direction; if not slotting, a mold gap can be occupied after one wiring device finishes working, the wiring device in the other direction can only leak the gap working, so that the phenomenon of few wires is caused, the quality of products is influenced, and if not slotting, and when the wiring device finishes working, the mold is moved out, the wiring tube is provided with yarns, the periphery of the mold is different from the wiring height, so that the yarns are required to warp upwards, the wiring working in the other direction is influenced, and even the wiring device is taken out of the mold, so that the mess of wires is caused.
The transverse and longitudinal frames of the die are respectively formed into a slotting structure 51, the slotting structure comprises a plurality of slot bodies 511, and the number of the width and the height of the slot bodies matched with the gaps of the die is the number of the gaps of the die minus one;
the longitudinal wiring module and the transverse wiring module respectively comprise a servo motor, a speed reducer, a sliding rail, a driving wheel, a transmission shaft, a synchronous belt, a wire locking structure and a wiring structure, wherein the wiring structure comprises a wiring pipe 21;

the push plate 92 of the automatic production equipment slotting and grease pushing module is in a retracted state when the wiring module works, so that space is reserved for the wiring tube. Since the resin is a very expensive raw material, after the grating is manufactured, the push plate 92 moves towards the direction of the die under the pushing of the pushing device 91, and the small teeth 93 corresponding to the groove body on the push plate push the resin raw material entering the groove body back into the die, so that the cost is saved.
The longitudinal wiring module and the transverse wiring module adopt a 'mouth' -shaped wiring mode;
the clamping and shearing module 4 consists of two strips of protruding teeth, a rectangular part with a groove, pushing devices 44 and 45, wherein the rectangular part 41 with the groove is fixedly arranged, the rectangular part 42 with the protruding teeth is tightly attached to the rectangular part 41 with the groove, when the two parts are overlapped under the action of the pushing device 45, the rectangular part 43 with the protruding teeth plays a role of scissors and shears yarns, a certain gap is reserved between the rectangular part 43 with the protruding teeth and the rectangular part 41 with the groove, when the two parts are overlapped under the action of the pushing device 44, the yarns are not sheared due to the existence of the gap, and the yarns are only clamped;

The winch is connected with the pressing knife through a steel wire rope and drives the pressing knife to move up and down. The vibration exhaust device adopts an integral vibration exhaust mode. The gap is stressed uniformly, and the time for vibration and exhaust is shortened greatly.
The electrical control module 8 is a PLC touch screen integrated machine, so that motion control of the whole equipment is realized, the volume of an electrical system is greatly reduced, the application of electrical parts is reduced, and automatic, manual and pause control can be realized.
The working process of the longitudinal wiring module is as follows:
before starting, the device automatically detects whether all modules are at the starting position, and if not, the device automatically resets and then starts working. The wiring tube reserves yarns with a certain length, the original position of the wiring module is at the outer side of the clamping and shearing module, when all the wiring tubes 21 pass through the clamping and shearing module, the pushing device 44 of the clamping and shearing module acts to clamp the reserved yarns, and when the wiring tubes 21 reach the upper part of the gap at the most edge of the die, the wiring tubes are driven by the servo motor 24 to descend into the lowest end of the gap of the die; the wiring structure starts to move longitudinally along the mould to finish the wiring work, after the wiring structure reaches the end, the whole longitudinal wiring structure is transversely moved to the right by a module distance under the action of the pushing device 25, then the wiring tube 21 is lifted by a small distance, and the distance is higher than the height of the original laid yarn, so that the resistance is increased if the lower side is not moved upwards, and the elastic wiring tube is possibly not vertical. Then the structure is backward, when the structure is going to the head, the tightening and shearing device is to be loosened, the wiring tube presses the reserved yarns together, the head-to-head pushing device transversely moves the whole longitudinal wiring structure leftwards, and because the leftmost yarn is still in a tilting state at the moment, in order not to influence the following operation, when the structure is close to the initial position, the wiring tube is upwards moved to a position exceeding the leftmost yarn height, and is pushed to the end and then pressed down, so that all yarns are pressed into a plane, and all yarn paths are in a shape of a Chinese character 'kou'. Then the wiring pipe is retracted into the mould slot, a working space is reserved for the transverse wiring module, at the moment, the longitudinal wiring module locking structure 22 locks the yarn under the action of the pushing device 23, and the clamping and shearing module clamps the reserved yarn again;
the working process of the transverse wiring module 2 is the same as that of the longitudinal wiring module 3. In the wiring mode of the shape of the Chinese character 'kou', two uniform yarns are arranged in all gaps after wiring, and no few lines exist, so that the product quality is ensured;
after the first-round wiring is completed, the resin pouring module 6 starts to pour resin, after the pouring is completed, a new layer of wiring is started, and the process is repeated for a plurality of times until the last layer of yarn wiring is completed, and after the second-round resin pouring is completed, the vibration exhaust module 7 descends to the proper position to press all the well-distributed yarns. The clamping and shearing module loosens the yarn, the transverse and longitudinal wiring structures fall back to the initial positions, the yarn locking structure 22 locks the yarn, and the yarn passes through the clamping and shearing module in the process, and the shearing device acts to cut the yarn; the slotting and grease pushing module pushes out resin in the slot body, and the vibration exhaust module starts to work; when the vibration exhaust module works and returns to the initial position, the resin pouring module runs again, resin is not poured in the operation, and only the scraping plate works, so that the resin moving out of a die gap in the vibration process is scraped, and the waste of the resin can be reduced, and the cost is saved; the heating electromagnetic valve is automatically opened to start the curing work, when the resin is solidified and is not completely hardened, the push plate 92 of the slotting and grease pushing module 9 is retracted so as to prevent the push plate small teeth 93 from being adhered to the glass fiber reinforced plastic grille after complete curing, and after the setting curing time is up, the audible and visual alarm 11 starts to alarm to remind workers of finished products.
The mold can be two or more, meanwhile, the bottom of the equipment support is fixedly provided with the rail rolling wheels and the brake device, production operation is carried out on a plurality of molds of the same type which are longitudinally arranged, the time for one mold operation to finish curing and demolding can automatically enter the next mold along the rail for operation, thereby realizing continuous production of the glass fiber reinforced plastic grating, greatly improving the equipment utilization rate, and the method is not limited by the embodiment.
The foregoing detailed description of the application has been presented for purposes of illustration and description, but is not intended to limit the scope of the application, i.e., the application is not limited to the details shown and described.
