Description

Technical Field

[0001] This invention relates to the field of grating surface treatment technology, and in particular to a surface treatment system for molded fiberglass grating automated production line products. Background Technology

[0002] Fiberglass grating, also known as fiberglass grating, is a type of plate-like material with many openings, made of fiberglass as reinforcement and unsaturated polyester resin as the matrix, through a special processing and composite process. Fiberglass grating can be used as a structural material for floors, trench covers, platforms, ship decks, stairs, walkways, etc., in corrosive environments. It features corrosion resistance, flame retardancy, non-magnetic insulation, bright colors, and a variety of styles and forms to choose from.

[0003] The automated production line for molded fiberglass grating produces fiberglass grating by shaping it with molds. The molded fiberglass grating is then moved to various processing sections by conveyor belts or other transportation mechanisms for further processing.

[0004] The space between the molded fiberglass gratings contains resin sheets that need to be removed. Also, there may be burrs on the surface of the grating during molding. In the existing technology, workers need to manually remove the resin sheets inside the space and polish the burrs on the surface of the grating. However, this process is labor-intensive and results in low surface treatment efficiency. Summary of the Invention

[0005] To improve the efficiency of grating surface treatment, this application provides a surface treatment system for molded fiberglass grating automated production line products.

[0006] The surface treatment system for the automated production line of molded fiberglass grating provided in this application adopts the following technical solution: A surface treatment system for an automated production line of molded fiberglass grating includes a frame and a fixed bracket mounted on the frame. A pressure plate is slidably mounted on the fixed bracket, and several detachable pressure plates are mounted on the bottom of the pressure plate. The fixed bracket is equipped with a drive assembly for moving the pressure plate so that the detachable pressure plates insert into the fiberglass grating spaces and push out resin sheets. The frame is also equipped with a grinding assembly for grinding the surface of the fiberglass grating.

[0007] By adopting the above technical solution, when the transport mechanism moves the FRP grating to the bottom of the fixed support, the drive component drives the pressure plate to move, so that the detached pressure plate is inserted into the FRP grating space and pushes out the resin sheet. Then, the drive component drives the pressure plate to reset, so that the detached pressure plate is flattened and removed from the FRP grating space. The transport mechanism then moves the FRP grating to the grinding component, and the grinding component grinds the surface of the FRP grating. The operation is simple and convenient. The removal of the pressure plate and the grinding operation are all completed by the component, reducing labor intensity and thus improving the efficiency of grating surface treatment.

[0008] Preferably, the drive assembly includes a drive cylinder and a drive guide column. The drive guide column is slidably mounted on a fixed bracket and connected to a pressure plate. The drive cylinder is mounted on the fixed bracket, and the piston rod of the drive cylinder is connected to the pressure plate.

[0009] By adopting the above technical solution, the driving cylinder is started and drives the pressure plate to slide. At this time, the driving guide column follows the pressure plate to slide, which improves the stability of the pressure plate sliding and realizes the driving. The operation is simple and convenient, and it is easy to use, which improves the efficiency of resin sheet detachment in the grid.

[0010] Preferably, the polishing assembly includes a polishing motor and a polishing wheel. The frame is provided with a guide rod, and a movable block is slidably disposed on the guide rod. The polishing wheel is rotatably disposed on the movable block, and the polishing motor is disposed on the movable block. The rotating shaft of the polishing motor is connected to the polishing wheel. The frame is provided with a moving component, which is used to drive the movable block to slide back and forth along the length direction of the guide rod.

[0011] By adopting the above technical solution, when the grid moves to the bottom of the moving block, the grinding wheel contacts the grid surface. At this time, the grinding motor is started to drive the grinding wheel to rotate and grind the grid surface. At the same time, the moving component drives the moving block to slide back and forth along the length of the guide rod, thereby driving the grinding wheel to move on the grid surface, thus grinding various positions on the grid surface. The operation is simple and convenient, improving the convenience of grinding the grid surface.

[0012] Preferably, the polishing assembly further includes a polishing block, which is rotatably connected to the moving block and connected to the shaft of the polishing motor. The bottom of the polishing block is provided with multiple telescopic columns, which connect the polishing block and the polishing wheel. An auxiliary spring is sleeved on the telescopic column, with one end of the auxiliary spring abutting against the polishing block and the other end of the auxiliary spring abutting against the polishing wheel.

[0013] By adopting the above technical solution, the auxiliary spring and the telescopic column slide to connect the grinding wheel and the grinding block, so that after the grinding wheel abuts against the grid surface, it can compress the auxiliary spring according to the thickness of the grid surface, thereby always abutting against the grid surface for grinding, improving the stability of the grid surface grinding.

[0014] Preferably, the moving component includes a moving motor, a moving chain, and a pair of moving sprockets. The moving sprockets are rotatably mounted on the frame, the moving chain is meshed with the moving sprockets, the moving motor is mounted on the frame, the moving motor shaft is connected to one of the moving sprockets, and the moving block is connected to the moving chain.

[0015] By adopting the above technical solution, the mobile motor is started and drives the mobile sprocket to rotate, which in turn drives the mobile chain to move, thereby driving the mobile block to move along the length of the guide rod. The operation is simple and convenient, easy to use, and improves the convenience of grinding the grid surface.

[0016] Preferably, the frame is provided with an adjustment component for adjusting the height of the guide rod, the moving block is provided with a connecting column whose length direction is along the height direction of the guide rod, and the moving chain is provided with a connecting block, the connecting block being slidably connected to the connecting column.

[0017] By adopting the above technical solution, the adjustment component can adjust the height of the guide rod, thereby adjusting the height of the moving block, so that the grinding wheel can abut against the surface of the grid, facilitating the grinding of the grid surface. At the same time, a connecting column and a connecting block are set up. When the height of the guide rod is adjusted, the moving block moves up and down. Through the relative sliding between the connecting column and the connecting block, the connection between the moving chain and the moving block is not affected by the adjustment component's adjustment of the guide rod height. This facilitates the adjustment of the height of the guide rod and the moving block to suit grids of different specifications and facilitates the grinding of the grid surface.

[0018] Preferably, the frame is provided with a side plate, and the adjustment assembly includes an adjustment plate, an adjustment screw and an adjustment handwheel. The adjustment plate is slidably disposed on the side plate and connected to the guide rod. The adjustment screw is rotatably disposed on the frame. The adjustment screw is threaded through the adjustment plate, and the adjustment handwheel is disposed on the adjustment screw.

[0019] By adopting the above technical solution, rotating the adjusting handwheel drives the adjusting screw to rotate, thereby moving the adjusting plate up and down, and realizing the up and down movement of the guide rod. The operation is simple and convenient, and easy to use.

[0020] Preferably, the side plate is provided with a limiting groove, and the adjusting plate is provided with a limiting wheel that slides into the limiting groove and can rotate in the limiting groove.

[0021] By adopting the above technical solution, the limiting wheel rolls as it slides up and down in the limiting groove, thereby reducing friction and facilitating the up and down adjustment of the adjusting plate. At the same time, the limiting wheel abuts against the inner wall of the limiting groove, thereby improving the stability of the up and down movement of the adjusting plate.

[0022] Preferably, the moving chain is equipped with a cleaning rod that can hold the detached pressure plate against and clean it. The cleaning rod is also equipped with a cleaning box that is located below the cleaning rod and has an opening.

[0023] By adopting the above technical solution, when the resin sheet is pushed out of the grid space by the detachment pressure plate, the resin sheet may stick to the detachment pressure plate due to excessive pressure. When the moving chain rotates and drives the moving block to move in conjunction with the grinding component to perform grinding, the cleaning rod moves and rubs the detachment pressure plate to clean it. The cleaning rod pushes the resin sheet stuck to the detachment pressure plate, causing the resin sheet to fall into the cleaning box. No manual cleaning is required, which is convenient to use.

[0024] Preferably, the pressure plate is provided with an air intake groove, the detached pressure plate is provided with an auxiliary air intake groove communicating with the air intake groove, the pressure plate is provided with a negative pressure component, the negative pressure component is used to perform a negative pressure operation on the air intake groove, the auxiliary air intake groove is used to adsorb the resin sheet under the detached pressure plate, a sliding block is slidably provided in the air intake groove, the sliding plate is provided with an air inlet groove that can communicate with the auxiliary air intake groove, the pressure plate is slidably provided with an air inlet pipe, the air inlet pipe is slidably inserted into the air intake groove and connected to the sliding block, the air inlet pipe communicates with the air inlet groove, the air inlet pipe is provided with an assembly block, the assembly block is connected to a cleaning rod, the cleaning rod can abut against and push the assembly block to move, the air intake groove is provided with a reset component, the reset component is used to reset after the sliding block moves.

[0025] By adopting the above technical solution, when the resin sheet is removed, a negative pressure component draws a negative pressure when the removed sheet is inserted into the space. This causes the removed resin sheet to be adsorbed through the suction groove and the auxiliary suction groove. When the moving chain moves, it drives the cleaning rod to move, which in turn drives the air inlet pipe through the assembly block. This causes the sliding block to move in the suction groove. When the sliding block moves and the auxiliary suction groove connects with the air inlet groove, the air inlet pipe injects air into the auxiliary suction groove. Combined with the push of the cleaning rod, the previously adsorbed resin sheet falls into the cleaning box below, thus fully recovering the removed resin sheet, realizing material recycling, and improving the overall cleanliness of the workshop.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By setting up a frame, fixed bracket, pressure plate, detaching pressure plate and drive assembly, after the FRP grating is placed under the fixed bracket of the frame, the pressure plate is moved by the drive assembly, so that the electric detaching pressure plate is inserted into the space of the grating, thereby pushing out the resin sheet in the space of the grating and completing the detachment operation of the FRP grating. There is no need to manually remove the resin sheet, reducing labor intensity and improving the convenience of grating processing. By setting up a grinding motor, grinding wheel, guide rod, moving block and moving component, after the grid is placed under the grinding wheel, the grinding motor is started to drive the grinding wheel to rotate, thereby grinding the grid surface. At the same time, the moving component can drive the moving block to move back and forth along the guide rod, thereby increasing the grinding range, better grinding the grid surface, reducing labor intensity and improving the convenience of grid surface processing. By setting up a grinding block, telescopic column, and auxiliary spring, when the grinding wheel presses against the surface of the grating for grinding, the surface of the grating may have undulations. During the movement of the grinding wheel, the telescopic column extends and retracts back and forth, and the auxiliary spring retracts and presses against the surface, thereby changing the distance between the grinding block and the grinding wheel, so that the grinding wheel always presses against the surface of the grating, thereby improving the grinding effect and improving the quality of the grating surface processing.

The grinding block 52 is positioned below the moving block 42 and is fixedly connected to the shaft of the grinding motor 51. A telescopic column 521 is fixedly mounted on the bottom wall of the grinding block 52. The end of the telescopic column 521 away from the grinding block 52 is fixedly connected to the grinding wheel 53, allowing the grinding wheel 53 to slide vertically with the grinding block 52. Each telescopic column 521 is fitted with an auxiliary spring 522, with both ends of the auxiliary spring 522 connected to the bottom wall of the grinding block 52 and the top wall of the grinding wheel 53, respectively. The frame 1 is equipped with a moving assembly 6 for driving the moving block 42 to slide back and forth along the length of the guide rods 4. The grinding motor 51 drives the grinding block 52 and grinding wheel 53 to rotate for grinding. In conjunction with the moving component 6, the moving block 42 moves to achieve the grinding process on the surface of the grid, which is convenient to use.

[0037] For ease of use, please refer to Figure 1 and Figure 2 The moving component 6 includes a moving motor 61, a moving chain 63, and a pair of moving sprockets 62. The moving sprockets 62 are rotatably mounted on the frame 1 and positioned between the guide rod 4 and the fixed bracket 2. The moving chain 63 is meshed with the moving sprockets 62. The moving motor 61 is mounted on the frame 1, and its shaft is connected to one of the moving sprockets 62 via a transmission structure, which can be a bevel gear structure.

The frame 1 is equipped with an adjusting component 7 for adjusting the height of the guide rod 4. The moving motor 61 drives the moving chain 63 to rotate via the moving sprockets 62, thereby causing the moving block 42 to move along the guide rod 4.

[0038] To improve applicability, refer to Figure 1 and Figure 2The adjusting assembly 7 includes a pair of adjusting plates 71, a pair of adjusting screws 72, and a pair of adjusting handwheels 73 (the screw threads are not shown in detail in the figure).

By adjusting the handwheel 73 to rotate the adjusting screw 72, the adjusting plate 71 can be moved, thereby adjusting the height of both ends of the guide rod 4 so as to be used for different subsequent grid surface processing and polishing, thus improving applicability.

[0039] Embodiment 1 of this application discloses a surface treatment system for an automated production line of molded fiberglass gratings. Based on the treatment system of Embodiment 1, and referring to... Figure 3 and Figure 4 The top wall of the pressure plate 21 is also fixedly equipped with an air suction pump 212 as a negative pressure component. An air suction groove 211 is provided inside the pressure plate 21, and an auxiliary air suction groove 221 communicating with the air suction groove 211 is provided on the bottom wall of the detached pressure plate 22. The air suction pump 212 is connected to the air suction groove 211 through a pipe to provide negative pressure, allowing the auxiliary air suction groove 221 to adsorb the resin sheet under the detached pressure plate 22. Some grid openings have a structure that is wider at the top and narrower at the bottom, thus requiring the adsorption and removal of the ejected resin sheet. During the process of the detached pressure plate 22 ejecting the resin sheet, the air suction pump 212 is activated, adsorbing the detached resin sheet onto the detached pressure plate 22 after it detaches, reducing the possibility of resin sheets flying around and affecting the cleanliness of the workshop.

[0040] In order to recycle resin sheets, refer to Figure 3 and Figure 4 A cleaning rod 632 is fixedly installed on the side wall of the lower section of the moving chain 63. The end of the cleaning rod 632 away from the moving chain 63 is slidably connected to the fixed bracket 2. The top wall of the cleaning rod 632 is slightly lower than the bottom wall of the detached pressure plate 22. The cleaning rod 632 passes under the fixed bracket 2 and can contact the bottom wall of the detached pressure plate 22 to clean it. A cleaning box 633 with a top opening is detachably installed below the cleaning rod 632 by bolts or other means. When the detached grid moves to the rear end for grinding, the reset pressure plate 21 is reset. The moving chain 63 drives the moving block 42 to move, and at the same time, it drives the cleaning rod 632 to clean the reset detached pressure plate 22, pushing the adsorbed resin sheet into the cleaning box 633 for recycling.

[0041] For ease of use, please refer to Figure 4 and Figure 5 A sliding block 8 is slidably disposed within the air intake groove 211. The top and bottom walls of the sliding block 8 abut against the inner wall of the air intake groove 211. The bottom wall of the sliding block 8 has an air inlet groove 81 that connects to the auxiliary air intake groove 221. An air inlet pipe 82 is slidably disposed on the pressure plate 21, capable of being inserted into the air intake groove 211. The air inlet pipe 82 is slidably connected to the pressure plate 21 and fixedly connected to the sliding block 8. Both ends of the air inlet pipe 82 are open and connected to the air inlet groove 81. The air inlet pipe 82 and the pressure plate 21 are sealed to reduce the possibility of air leakage into the air intake groove 211. An assembly block 821 is fixedly disposed on the air inlet pipe 82, fitting against the side wall of the pressure plate 21. During the movement of the cleaning rod 632, it can abut against the assembly block 821 and push the assembly block 821 to slide. A return spring 822 is sleeved on the air inlet pipe 82 as a reset element, and the return spring 822 connects the sliding block 8 to the inner wall of the air intake groove 211. During the movement of the cleaning rod 632, the air inlet pipe 82 is pushed to move by the assembly block 821, which in turn drives the sliding block 8 to move. When the cleaning rod 632 moves to the detached pressure plate 22, the sliding block 8 moves and connects the air inlet groove 81 and the air intake auxiliary groove 221 of the detached pressure plate 22 at that location. At this time, the air inlet pipe 82 supplies air, making the resin plate easier to detach under the push of the cleaning rod 632, thus improving the convenience of use.

[0042] The implementation principle of the surface treatment system for the molded fiberglass grating automated production line in this application embodiment is as follows: The fiberglass grating is placed under the fixed bracket 2, and the drive cylinder 31 is started to drive the pressure plate 21 to press down, so that the detachable pressure plate 22 is inserted into the grating space, pushing out the resin sheet and completing the detachment process. Then, the grating is moved under the grinding block 52, so that the grinding wheel 53 abuts against the grating surface. Then, the grinding motor 51 is started to drive the grinding wheel 53 to rotate for grinding. At the same time, the moving motor 61 is started, and the moving block 42 and the grinding wheel 53 are moved through the chain and sprocket transmission to achieve grinding of the grating surface. The operation is simple and convenient. Compared with manual processing, it reduces labor intensity and improves the efficiency of grating surface processing.

[0043] 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.
