Description

Technical Field

[0001] The invention belongs to the technical field of glass fiber reinforced plastic grating processing, in particular to a surface cleaning device for glass fiber reinforced plastic grating production. Background Art

[0002] FRP grating, also known as FRP grating, is a special composite material product. Due to the addition of glass fiber and some other substances, it has great strength and toughness. In order to improve the corrosion resistance, anti-slip and aesthetics of the FRP grating after production, the FRP grating will be surface treated after forming. The specific operation is to polish the surface of the FRP grating.

[0003] In the prior art, when surface treatment is performed on the formed FRP grating, the demolded FRP grating is sent into a grinder and surface polished by the grinding roller inside the grinder. However, since the area of the demolded FRP grating is too large, moving it to the grinder requires not only crawler transport but also positioning of the FRP grating on the crawler. The above-mentioned transport method not only affects the working cycle but also causes some additional transportation costs. The debris after grinding can only remain inside the grinder. If it is not cleaned regularly, it will also affect the rotation of the internal grinding roller, which will ultimately affect the use of the grinder.

Since both sides of the grating plate are in contact with the abutment block, the grinding process will not cause poor grinding effect due to displacement of the grating plate. At this time, the grating plate can be automatically polished after demolding. This integrated design of grating plate production and surface cleaning not only eliminates the transportation process, but also enables the grating plate after demolding to be surface-treated more quickly, thereby avoiding the problem of impurities hardening and being difficult to handle due to long-term non-treatment.

When the grinding roller cleans the surface of the grating plate, the pulling cloth will pull the collecting cloth through the tightening rope, so that the collecting cloth is unfolded under the grating plate, thereby collecting the grinding debris.

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0030] Example 1

[0031] like Figures 1 to 8 As shown, a surface cleaning device for glass fiber reinforced plastic grating production according to an embodiment of the present invention includes a base frame 1, an operating platform 2 is provided at the upper end of the base frame 1, a production structure 3 is provided at the upper end of the operating platform 2, and the production structure 3 is used to produce grating plates 5, and a cleaning structure 4 is provided at the upper end of the production structure 3; the production structure 3 includes: a mold 31, the mold 31 is provided with the surface of the operating platform 2; a casting bottom plate 32, the casting bottom plate 32 is provided at the lower end of the mold 31, and the casting bottom plate 32 is in contact with the bottom of the mold 31; a push rod 33, the push rod 33 is provided at the bottom of the casting bottom plate 32; the cleaning structure 4 includes : Electronic track 401, electronic track 401 is arranged at the upper end of the operating platform 2; grinding roller 403, grinding roller 403 is slidably connected to the upper end of the mold 31, and the electronic track 401 is used to control the movement of the grinding roller 403; rotating shaft 422, rotating shaft 422 is rotatably connected to the side wall of the operating platform 2; placing plate 409, placing plate 409 is rotatably connected to the arc surface of the rotating shaft 422, and the surface of placing plate 409 is used to place grid plate 5; limiting plate 423, limiting plate 423 is arranged at the lower end of placing plate 409, and limiting plate 423 is in contact with the bottom of placing plate 409.

[0032] Specifically, the solution is a surface cleaning device for glass fiber reinforced plastic grating production, which is used to process the grating plate 5 of glass fiber reinforced plastic grating. When in use, it is first necessary to prepare the raw materials for preparing the grating plate 5, which are unsaturated resin, glass fiber yarn and calcium powder. These raw materials are mixed together in a certain proportion and stirred to ensure that the components are evenly distributed. Then the mixed raw materials are poured into the pre-made mold 31. At this time, the casting liquid on the mold 31 is scraped flat with a scraper, and then the yarn is drawn towards the gap of the mold 31. This operation can not only increase the flow rate of the casting liquid, but also ensure that the produced grating plate 5 has good strength and toughness. After the casting liquid has spread the yarn and the casting liquid fills the mold 31, Use a scraper to level it, collect the remaining material, and solidify it for a period of time at any time to complete the forming of the grid plate 5. Then start the push rod 33, the push rod 33 will push it upward and move in the gap of the mold 31 to push the formed grid plate 5 out of the mold 31, and complete the demoulding of the grid plate 5. Since the surface of the grid plate 5 coming out of the mold 31 usually has impurities solidified from the excess casting liquid, if it is not cleaned and polished in time, it may cause the surface to be uneven when it is pressed by heavy objects during later use, and even affect the appearance. In order to solve the above problem, the demoulded grid plate 5 is usually transported to a grinder and polished by the grinding roller 403 inside the grinder. However, since the area of the demoulded grid plate 5 is too large, the surface of the demoulded grid plate 5 is too large. 9. The grating 5 is large and needs to be moved to the grinding machine not only for transport by crawler belts, but also for positioning of the fiberglass grating on the crawler belts. This transport method not only causes some additional transportation costs, but also takes up a lot of space, which is very inconvenient. For this reason, a cleaning structure 4 is set above the device. After the grating plate 5 is demoulded, the top rod 33 will push the grating plate 5 to contact the bottom surface of the placement plate 409, and then the placement plate 409 will rotate along the rotating shaft 422. After the grating plate 5 passes through the placement plate 409, since there is no abutment of the grating plate 5, the placement plate 409 will automatically reset at this time, and the limit plate 423 under the placement plate 409 will also keep the placement plate 409 in a horizontal state. Then the top rod 33 moves downward, and the grating plate 5 will be moved to the surface of the placement plate 409 under the drive of the push rod 33 and placed, and then the electronic track 401 will be started. The electronic track 401 will transmit electricity to the grinding roller 403, so that the grinding roller 403 slides along the inner wall of the electronic track 401, and in the process of moving the grinding roller 403, the grinding roller 403 itself will also rotate. When the grinding roller 403 moves to the track of the lower half of the electronic track 401, it will contact the grid plate 5 on the placement plate 409, thereby grinding the surface of the grid plate 5. After the grid plate 5 is demoulded, the grid plate 5 can be cleaned and polished immediately. The device realizes the integration of production and cleaning, abandons the traditional crawler transportation, reduces the occupied space, and is very convenient.

[0033] like Figures 1 to 7As shown, the production structure 3 also includes: a lifting frame 34, the lifting frame 34 is slidably connected to the inside of the base frame 1, and the lifting frame 34 is connected to the top rod 33; the cleaning structure 4 also includes: a moving frame 402, the moving frame 402 slides on the inner wall of the electronic track 401, and the bottom of the moving frame 402 is rotatably connected to the grinding roller 403; a placing frame 408, the placing frame 408 is arranged at one end of the side wall of the operating platform 2 close to the placing plate 409, and the rotating shaft 422 is connected to the placing frame 408.

[0034] Specifically, when the grille plate 5 needs to be demolded, the lifting frame 34 is started, and the lifting frame 34 can drive the top rod 33 to move upward, and the electronic track 401 is started, and the electronic track 401 will drive the moving frame 402 to move on the inner wall of the track, and the grinding roller 403 will also rotate on the surface of the moving frame 402, so that the grille plate 5 can be ground.

[0035] like Figure 6 As shown, the arc surface of the rotating shaft 422 is covered with a third coil spring 421 , and one end of the third coil spring 421 is connected to the placement plate 409 , and the other end of the third coil spring 421 is connected to the placement frame 408 .

[0036] Specifically, by providing a third coil spring 421 at one end of the placement plate 409, when the grid plate 5 is lifted and bent by the placement plate 409 and finally needs to be reset, the third coil spring 421 can release the elastic force and drive the placement plate 409 to reset more quickly.

[0037] like Figures 5 and 6 As shown, a plurality of protective pads 410 are provided on the upper surface of the placement plate 409 , and the protective pads 410 are in contact with the lower surface of the grid plate 5 .

[0038] Specifically, by setting a protective pad 410 on the surface of the placement plate 409, the wear of the grille plate 5 by the placement plate 409 can be reduced when the grille plate 5 falls on the placement plate 409, and when the grinding roller 403 grinds the grille plate 5, the protective pad 410 can also increase the friction between the grille plate 5 and the placement plate 409, making the grille plate 5 more stable.

[0039] like Figures 1 to 8 As shown, shielding plates 406 are provided at both ends of the lifting frame 34 , and a sensor 405 is provided at one end of the side wall of the operating platform 2 close to the electronic track 401 , and the sensor 405 is connected to the electronic track 401 .

[0040] Specifically, by setting a sensor 405 on the side wall of the operating platform 2, the sensor 405 is a photoelectric sensing instrument, and the photodiode on its surface will emit light. When the lifting frame 34 lifts the grid plate 5, the shielding plate 406 located on the side of the lifting frame 34 will also move upward. When the shielding plate 406 is detected, the shielding plate 406 will block the light emitted by the photodiode, and the resistance value of the photodiode changes, thereby generating an electrical signal and transmitting it to the electronic track 401, so that the electronic track 401 starts to move with the moving frame 402, thereby realizing the automatic opening of the electronic track 401.

[0041] like Figures 1 to 6 As shown, the surfaces of the placement frame 408 and the placement plate 409 are both provided with a slide rail 420 , and the inner wall of the slide rail 420 is slidably connected with an abutment block 417 , which abuts against the grid plate 5 .

[0042] Specifically, by setting the abutment block 417, when the grinding roller 403 is grinding the grid plate 5, the abutment block 417 is started, and the abutment block 417 will move along the slide rail 420 toward the grid plate 5, and finally clamp the grid plate 5, so that the grid plate 5 can be fixed during grinding, preventing the grid plate 5 from shifting during the grinding process.

[0043] like Figures 1 to 6 As shown, one end of the side wall of the operating platform 2 close to the placement frame 408 is rotatably connected to a screw rod 418 , and the screw rod 418 is threadedly connected to the abutment block 417 .

[0044] Specifically, when the abutment block 417 needs to clamp the grille plate 5, it is only necessary to start the screw 418 to rotate. Since the abutment block 417 is threadedly connected to the screw 418 and the abutment block 417 slides on the inner wall of the slide rail 420, the abutment block 417 will move toward the grille plate 5 at this time, and finally clamp and fix the grille plate 5.

[0045] like Figures 6 to 8 As shown, a rack 404 is provided on the inner wall of the shielding plate 406 , and a gear 419 is provided at one end of the screw rod 418 , and the gear 419 is meshed with the rack 404 .

[0046] Specifically, by providing a rack 404 on the inner wall of the shielding plate 406, when the lifting frame 34 drives the shielding plate 406 to move upward, the rack 404 will engage with the gear 419 at one end of the screw 418, and finally the gear 419 will drive the screw 418 to rotate together, so that the abutment block 417 can automatically move toward the grille plate 5 when the grille plate 5 rises.

[0047] Example 2

[0048] like Figures 4 to 7 As shown, compared with Example 1, another embodiment of the present invention is: the upper end of the operating platform 2 is rotatably connected to one end of one of the two placement frames 408, and the arc surface of the unwinding shaft 411 is covered with a collecting cloth 412; the upper end of the operating platform 2 is rotatably connected to one end of the other of the two placement frames 408, and the arc surface of the pulling shaft 414 is covered with a pulling cloth 416, and a tightening rope 407 is connected between the pulling cloth 416 and the collecting cloth 412.

[0049] Specifically, by setting a pulling cloth 416 on the operating platform 2, when the grid plate 5 is polished, the pulling shaft 414 is started to rotate, and the pulling cloth 416 located on the arc surface of the pulling shaft 414 will pull the collecting cloth 412 toward the pulling shaft 414 through the tightening rope 407, and finally unfold the collecting cloth 412 under the grid plate 5, so as to collect the debris generated by polishing, thereby preventing these debris from falling onto the surface of the mold 31 and affecting the smoothness of the mold 31.

[0050] like Figures 4 to 7 As shown, the arc surface of the unwinding shaft 411 is covered with a first coil spring 413 , and the arc surface of the pulling shaft 414 is covered with a second coil spring 415 .

[0051] Specifically, by providing the first coil spring 413 and the second coil spring 415 , after the collecting cloth 412 has collected the debris, the first coil spring 413 and the second coil spring 415 can release their elastic force by simply stopping the rotation of the pulling shaft 414 , so that the collecting cloth 412 can automatically reset.

[0052] Working principle: When in use, first you need to prepare the raw materials for making the grid plate 5, which are unsaturated resin, glass fiber yarn and calcium powder. Mix these raw materials together in a certain proportion and stir them to ensure that the components are evenly distributed. Then pour the mixed raw materials into the pre-made mold 31. At this time, use a scraper to scrape the casting liquid on the mold 31 flat, and then draw yarn towards the gap of the mold 31. This operation can not only increase the flow rate of the casting liquid, but also ensure that the produced grid plate 5 has good strength and toughness. After the casting liquid has spread the yarn and the casting liquid fills the mold 31, use a scraper to level it, collect the remaining material, and then solidify it at any time. After a period of time, the forming of the grille plate 5 is completed, and then the push rod 33 is started. The push rod 33 will push up and move in the gap of the mold 31 to push the formed grille plate 5 out of the mold 31. The push rod 33 will push the grille plate 5 to contact the bottom surface of the placement plate 409, and then the placement plate 409 will rotate along the rotation axis 422. When the grille plate 5 passes through the placement plate 409, since there is no abutment of the grille plate 5, the placement plate 409 will automatically reset at this time, and the limit plate 423 under the placement plate 409 will also keep the placement plate 409 in a horizontal state. Then the push rod 33 moves downward, and the grille plate 5 will be on the belt of the push rod 33 The shielding plate 406 is moved downward to the surface of the placement plate 409 for placement, and in the process of the lifting frame 34 driving the shielding plate 406 to move upward, the rack 404 will mesh with the gear 419 at one end of the screw 418, and finally the gear 419 will drive the screw 418 to rotate together. Since the abutment block 417 is threadedly connected to the screw 418 and the abutment block 417 slides on the inner wall of the slide rail 420, the abutment block 417 will move toward the direction of the grid plate 5, and finally clamp the grid plate 5. At this time, the sensor 405 will also detect the shielding plate 406, and the shielding plate 406 will block the light emitted by the photodiode. The resistance of the photodiode The value changes, thereby generating an electrical signal and transmitting it to the electronic track 401, so that the electronic track 401 starts to move with the mobile frame 402, and the mobile frame 402 will move on the inner wall of the track, and the grinding roller 403 will also rotate on the surface of the mobile frame 402. When the grinding roller 403 moves to the track in the lower half of the electronic track 401, it will contact the grid plate 5 on the placement plate 409, thereby grinding the surface of the grid plate 5. After the grid plate 5 is demoulded, the grid plate 5 can be immediately cleaned and polished. The device realizes the integration of production and cleaning, abandons the traditional crawler transportation, reduces the occupied space, and is very convenient.
