Description

Technical Field

[0001] This invention relates to the field of thermoplastic glass fiber composite board bending technology, specifically to an automatic thermoplastic glass fiber bending machine. Background Technology

[0002] Thermoplastic glass fiber is an excellent reinforcing material. It is made from six minerals, namely pyrophyllite, quartz sand, limestone, dolomite, borocalcite, and boromagnesia, through high-temperature melting, drawing, winding, and weaving processes. After chemical surface treatment with silane coupling agents and wetting agents, it can be used to reinforce various thermoplastics, such as PA, PP, PS, AS, PC, PPC, ABS, PBT, PET and other thermoplastics.

[0003] Composite boards made of thermoplastic glass fiber as a reinforcing material and thermoplastic are typical advanced composite materials. They have many advantages such as convenient preparation, high strength, and impact resistance. They can also be bent to change their shape, thereby meeting the diverse needs of the market. They are widely used in aerospace, civil engineering and weaponry fields.

[0004] In existing technologies, bending machines are typically used to bend thermoplastic fiberglass composite panels. The principle is to heat the thermoplastic fiberglass composite panel to lower its yield point, and then bend it using mechanical force. However, because thermoplastic fiberglass composite panels are prone to dust adhesion during storage and transportation, the thermal stress generated by the high temperature and the mechanical force applied by the bending machine during the heating and bending process can cause impurities to adhere firmly to the thermoplastic fiberglass composite panel, resulting in defects in the cooled thermoplastic fiberglass composite panel.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] like Figures 1 to 4 As shown; an automatic thermoplastic glass fiber bending machine includes a bending machine 1. A cleaning box 2 is fixedly connected to the outer wall of the bending machine 1. The outer wall of the cleaning box 2 is provided with a discharge port 3 and a feed port 4. The discharge port 3 cooperates with the feeding device inside the bending machine 1 to feed thermoplastic glass fiber composite boards to the bending machine 1. Horizontally arranged support rollers 5 are uniformly rotatably connected to the inner wall of the cleaning box 2. A motor 6 is fixedly connected to the outer wall of the cleaning box 2. Feeding rollers 7 are symmetrically rotatably connected to the inner wall of the cleaning box 2. The components are connected by a belt for rotation. The main shaft of the motor 6 passes through the outer wall of the cleaning box 2 and is fixedly connected to the end wall of the conveying roller 7. Telescopic tubes 8 are evenly fixedly connected to the outer wall of the conveying roller 7. A suction cup 9 is hinged to the end of the telescopic tube 8 away from the conveying roller 7. Water pipes 10 are symmetrically fixedly connected to the inner wall of the cleaning box 2. A roller sleeve 11 communicating with the inside of the water pipe 10 is fixedly connected to one end of the water pipe 10. A cleaning roller 12 is provided on the inner wall of the roller sleeve 11. A cleaning sponge 13 is sleeved on the outer wall of the cleaning roller 12.

[0032] In use, the operator feeds the thermoplastic fiberglass composite board to be bent from the inlet 4 into the cleaning box 2, and starts the motor 6. The motor 6 drives the conveyor rollers 7 to rotate. The conveyor rollers 7 are connected by belts, so both conveyor rollers 7 rotate simultaneously. The rotation of the conveyor rollers 7 drives the telescopic tubes 8, which are evenly fixed to their outer walls, to rotate as well. The suction cups 9, hinged to the other end of the telescopic tubes 8, rotate with the telescopic tubes 8. When the thermoplastic fiberglass composite board enters the cleaning box 2, the bottom of the thermoplastic fiberglass composite board is in contact with the support rollers 5. When the suction cups 9 rotate, they contact the top of the thermoplastic fiberglass composite board. As the suction cups 9 rotate, they suck up the thermoplastic fiberglass composite board and squeeze and drag it, causing the thermoplastic fiberglass composite board to move along the support rollers 5. When the thermoplastic fiberglass composite board moves, it passes between two cleaning rollers 12. The outer wall of the cleaning rollers 12 is fitted with a cleaning sponge 13, which is in contact with the outer wall of the thermoplastic fiberglass composite board. As the thermoplastic fiberglass composite board moves, the cleaning sponge 13 wipes the outer wall of the thermoplastic fiberglass composite board, thereby removing the dust adhering to the outer wall of the thermoplastic fiberglass composite board. After wiping, the thermoplastic fiberglass composite board continues to move, leaving the cleaning box 2 from the discharge port 3 and entering the interior of the bending machine 1 for bending. This reduces the probability of defects appearing in the thermoplastic fiberglass composite board after bending due to residual impurities on the surface of the thermoplastic fiberglass composite board.

[0033] like Figure 4 , Figure 5 and Figure 6 As shown; the inner wall of the cleaning box 2 is fixedly connected to a first water storage box 14, the upper inner wall of the water storage box is fixedly connected to an inclined filter plate 15, the inner wall of the cleaning box 2 is fixedly connected to a second water storage box 16 which communicates with the lower interior of the first water storage box 14, the inner wall of the machine body is fixedly connected to a water pump 17, the water inlet of the water pump 17 communicates with the lower interior of the second water storage box 16, the interior of the cleaning roller 12 is hollow, the outer wall of the cleaning roller 12 is evenly provided with water outlet holes 18 that communicate with its interior, and the water outlet of the water pump 17 communicates with the interior of the water supply pipe 10.

[0034] The inner wall of the machine body is rotatably connected to a transmission rod 19, which is rotatably connected to the material conveying roller 7 via a belt. The outer wall of the cleaning roller 12 is rotatably and sealed to the inner wall of the roller sleeve 11. The cleaning roller 12 is rotatably connected to the transmission rod 19 via a belt.

[0035] The water supply pipe 10 is designed to be telescopic and arc-shaped. When the water supply pipe 10 is telescopic, it can drive the roller sleeve 11 to move around the transmission rod 19 as the center.

[0036] In order to enhance the cleaning effect of the cleaning sponge 13, a first water storage box 14 is fixedly connected inside the cleaning box 2. The lower interior of the first water storage box 14 is connected to the interior of the second water storage box 16. When the operator delivers the thermoplastic fiberglass composite board into the cleaning box 2 for cleaning, the water pump 17 is started simultaneously. The water pump 17 begins to draw water from the interior of the second water storage box 16, and then discharges the water from the outlet of the water pump 17 into the interior of the water supply pipe 10. The interior of the water supply pipe 10 is connected to the interior of the roller sleeve 11, and the interior of the roller sleeve 11 is connected to the interior of the cleaning roller 12. Therefore, the water discharged by the water pump 17 will enter the interior of the cleaning roller 12. The outer wall of the cleaning roller 12 is evenly provided with water outlet holes 18, so the water entering the interior of the cleaning roller 12 will be continuously... Water continuously flows out from the outlet 18 and is absorbed by the cleaning sponge 13. As more and more water flows out from the outlet 18, the water absorbed by the sponge overflows, allowing the water-saturated cleaning sponge 13 to wipe the thermoplastic fiberglass composite board. The impurities wiped off the thermoplastic fiberglass composite board mix with the water overflowing from the cleaning sponge 13 and then fall into the first water storage box 14 under the force of gravity, thereby increasing the cleaning effect of the cleaning sponge 13 on the thermoplastic fiberglass composite board. The wastewater falling into the first water storage box 14 falls to the top of the filter plate 15, which blocks the impurities in the water. The filtered water falls into the first water storage box 14 and then into the second water storage box 16. The water used to enhance the cleaning effect of the cleaning sponge 13 can be recycled.

[0037] Furthermore, the outer wall of the cleaning roller 12 is rotatably and sealed to the inner wall of the roller sleeve 11, so the cleaning roller 12 can rotate. When the conveying roller 7 rotates, it will drive the transmission rod 19 to rotate via the belt. The transmission rod 19 is rotatably connected to the cleaning roller 12 via the belt, so the rotation of the transmission rod 19 will synchronously drive the cleaning roller 12 to rotate. The rotation of the cleaning roller 12 will drive the cleaning sponge 13 to rotate together, so that the cleaning sponge 13 rotates to clean and wipe the thermoplastic fiberglass composite board, thereby increasing the cleaning effect of the cleaning sponge 13 on the thermoplastic fiberglass composite board.

[0038] Different types of thermoplastic fiberglass composite panels have different thicknesses, so the water supply pipe 10 is designed to be curved and extendable. When the water supply pipe 10 extends or retracts, it drives the roller sleeve 11 to move around the transmission rod 19 as the center. This ensures that even if the water supply pipe 10 extends or retracts, it will not affect the transmission rod 19's ability to rotate the cleaning roller 12. The water pressure generated by the water pump 17 continuously pumping water into the water supply pipe 10 will cause the water supply pipe 10 to lengthen. The water supply pipe 10 can also be shortened. Therefore, when thermoplastic fiberglass composite panels of different thicknesses pass through the cleaning roller 12, the thermoplastic... The outer wall of the glass fiber composite board is pushed by the cleaning sponge 13 against the cleaning roller 12, causing the cleaning roller 12 to push the water pipe 10 to shorten through the roller sleeve 11. The water pressure generated by the water inside the water pipe 10 causes the water pipe 10 to extend and push the roller sleeve 11. The roller sleeve 11, through the cleaning roller 12, drives the cleaning sponge 13 to adhere to the outer wall of the thermoplastic glass fiber composite board. This ensures that even if the thickness of the thermoplastic glass fiber composite board is different, the cleaning sponge 13 can adhere to the outer wall of the thermoplastic glass fiber composite board, thereby increasing the cleaning effect of the cleaning sponge 13.

[0039] like Figure 3 , Figure 4 , Figure 5 As shown; the inner wall of the first water storage box 14 is sealed with a sealing plate 20, which covers and seals the inner wall of the connection between the first water storage box 14 and the second water storage box 16. The inner wall of the first water storage box 14 is slidably connected with a buoyancy plate 21. The bottom of the buoyancy plate 21 is connected to the top of the sealing plate 20 by a rope. The top of the buoyancy plate 21 is fixedly connected with a needle plate 22. The top of the needle plate 22 is uniformly fixedly connected with pins 23 that can be inserted into the mesh of the filter plate 15. The outer wall of the cleaning box 2 is provided with a detachable impurity box 24. The inner wall of the first water storage box 14 is fixedly connected with an impurity outlet pipe 25. The impurity outlet pipe 25 passes through the first water storage box 14, the cleaning box 2, and the impurity box 24 in sequence and communicates with the interior of the impurity box 24. The bottom inner wall of the impurity outlet pipe 25 is at the same horizontal line as the top of the inclined part of the filter plate 15.

[0040] In use, to prevent the mesh of the filter plate 15 inside the first water storage box 14 from becoming clogged, thus preventing the filter plate 15 from filtering the water entering the first water storage box 14, a sealing plate 20 is hinged to the inner wall of the first water storage box 14. The sealing plate 20 covers and seals the inner wall of the connection between the first water storage box 14 and the second water storage box 16, preventing water entering the first water storage box 14 from entering the second water storage box 16. As more and more water enters the first water storage box 14, the liquid level in the first water storage box 14 gradually rises. As the liquid level in the first water storage box 14 rises, the buoyancy plate 21, which is slidably connected to the inner wall of the first water storage box 14, gradually moves upward under its own buoyancy. During the upward movement of the buoyancy plate 21, it drives the needle plate 22 to move upward as well. During the upward movement of the needle plate 22, the pins 23, which are evenly fixedly connected to the top of the needle plate 22, insert into the mesh of the filter plate 15, pushing out the impurities clogging the mesh and blocking the filter plate 15. The wastewater falling onto the filter plate 15 cannot pass through it and accumulates on top, carrying impurities into the impurity box 24 through the impurity outlet pipe 25, thus collecting the impurities. As the buoyancy plate 21 rises, it simultaneously pulls the sealing plate 20 via ropes, causing the sealing plate 20 to rotate and no longer seal the inner wall of the connection between the first water storage box 14 and the second water storage box 16, allowing water in the first water storage box 14 to drain into the second water storage box 16. As water from the first water storage box 14 is gradually discharged into the second water storage box 16, the liquid level in the first water storage box 14 gradually decreases. This causes the buoyancy plate 21 to descend, which in turn causes the ejector pin 23 to be pulled out of the mesh of the filter plate 15. During the descent of the buoyancy plate 21, the bottom of the buoyancy plate 21 pushes the top of the sealing plate 20, causing the sealing plate 20 to reset and cover and seal the inner wall of the connection between the first water storage box 14 and the second water storage box 16. This cycle continues to prevent the filter plate 15 from becoming clogged.

[0041] like Figure 4 , Figure 5 and Figure 6 As shown; a scraper 26 is fixedly connected to the outer wall of the roller sleeve 11, and one end of the scraper 26 is in contact with the outer wall of the cleaning sponge 13;

[0042] The scraper 26 is hollow inside, and the top of the scraper 26 is evenly provided with suction holes 27 communicating with its interior. The top of the first water storage box 14 is fixedly connected to a suction box 28 communicating with the interior of the scraper 26. A rotating rod 29 is rotatably connected to the lower inner wall of the suction box 28. A telescopic plate 30 is evenly fixedly connected to the outer wall of the rotating rod 29. The other end of the telescopic plate 30 contacts the inner wall of the suction box 28. One end of the rotating rod 29 penetrates the inner wall of the suction box 28 to its exterior and is fixedly connected to a gear 31. The top of the needle plate 22 is fixedly connected to a toothed plate 32. The toothed plate 32 penetrates the filter plate 15 and is slidably and sealed to the inner wall of the penetrated part. The toothed grooves on the toothed plate 32 mesh with the teeth of the gear 31. An air pump 33 is fixedly connected to the inner wall of the cleaning box 2. The air inlet of the air pump 33 communicates with the interior of the suction box 28.

[0043] The inner wall of the cleaning box 2 is fixedly connected to a U-shaped frame 34 with a hollow interior. The interior of the U-shaped frame 34 is connected to the air outlet of the air pump 33. The outer wall of the U-shaped frame 34 is uniformly fixedly connected to symmetrically arranged air drying pipes 35, and the interior of the air drying pipes 35 is connected to the interior of the U-shaped frame 34.

[0044] In use, the scraper 26 is fixedly connected to the roller sleeve 11. One end of the scraper 26 contacts the outer wall of the cleaning sponge 13, squeezing and scraping the sponge 13 to remove impurities adhering to it. This prevents the cleaning sponge 13 from becoming clogged with impurities and reducing its cleaning effect on the thermoplastic fiberglass composite board. To prevent impurities and water scraped off the cleaning sponge 13 from falling onto the outer wall of the thermoplastic fiberglass composite board, the scraper 26 is hollow inside. Suction holes 27 are evenly distributed on the top of the scraper 26. An air pump 33 is fixedly connected to the inner wall of the cleaning box 2. When the air pump 33 is running, it draws air from the suction box 28, which is connected to its air inlet. A rotating rod 29 is rotatably connected to the bottom of the suction box 28, and telescopic plates 30 are evenly fixedly connected to the outer wall of the rotating rod 29. The telescopic plates 30 seal the bottom of the suction box 28, allowing the air pump 33 to provide airflow to the inside of the scraper 26, thereby improving its cleaning effect. Water and impurities falling on scraper 26 are sucked into the interior of scraper 26 through suction holes 27, and then enter the interior of suction box 28. After entering the interior of suction box 28, they fall to the bottom of suction box 28 under their own gravity, while air enters air pump 33 and is discharged from its air outlet. When buoyancy plate 21 rises and falls, it drives toothed plate 32 to rise and fall together through needle plate 22. During the rise and fall, the toothed grooves on toothed plate 32 drive the gear 31 that meshes with it to rotate. During the rotation of gear 31, it drives rotating rod 29 to rotate together. Rotating rod 29 drives telescopic plate 30 to rotate. The rotation of telescopic plate 30 seals the bottom of suction box 28, while water between telescopic plates 30 is transported to the outside of suction box 28 by the rotating telescopic plate 30 and then enters the filter plate 15 in the first water storage box 14 and is filtered by filter plate 15.

[0045] To prevent water residue from remaining on the surface of the thermoplastic fiberglass composite board after cleaning, which could affect its bending, a hollow U-shaped frame 34 is fixedly connected to the inner wall of the machine body. The air outlet of the air pump 33 is connected to the inside of the U-shaped frame 34, so the air discharged by the air pump 33 enters the inside of the U-shaped frame 34 and is then discharged from the air drying pipe 35 connected to the U-shaped frame 34, blowing onto the surface of the thermoplastic fiberglass composite board that has passed through the U-shaped frame 34. This dries the water stains on the thermoplastic fiberglass composite board, thus allowing the water and impurities scraped off the cleaning sponge 13 by the scraper 26 to be absorbed into the first water storage box 14, while simultaneously drying the cleaned thermoplastic fiberglass composite board.

[0046] like Figure 5 and Figure 7 As shown; a meltblown fabric 36 is fixedly connected to the inner wall of the connection between the suction box 28 and the air inlet of the air pump 33;

[0047] The inner wall of the first water storage box 14 is sealed and fixedly connected with a sealing sleeve 37, which covers the toothed plate 32 and the bottom of the sealing sleeve 37 is sealed and fixedly connected to the top of the filter plate 15.

[0048] In use, the meltblown fabric 36 is a water-resistant but not air-resistant material. When the air pump 33 starts to draw air from inside the suction box 28, the meltblown fabric 36, which is fixedly connected to the inner wall of the connection between the suction box 28 and the air inlet of the air pump 33, can isolate water vapor. This prevents the air pump 33 from drawing out water vapor, which would result in a large amount of moisture in the air used to dry the thermoplastic glass fiber composite board, thus reducing the drying effect on the thermoplastic glass fiber composite board. In addition, to prevent impurities in the water falling on the filter plate 15 from entering the grooves on the toothed plate 32 and causing blockage of the grooves on the toothed plate 32, which would cause the toothed plate 32 to jam and prevent the toothed plate 32 from driving the gear 31 to rotate, a sealing sleeve 37 is fixedly connected to the inner wall of the first water storage box 14. The sealing sleeve 37 fits the toothed plate 32 inside, and its bottom is sealed and fixedly connected to the top of the filter plate 15, so that impurities in the water cannot enter the grooves on the toothed plate 32.

[0049] Working principle of this invention:

[0050] Refer to the attached instruction manual. Figures 1 to 4As shown, the operator feeds the thermoplastic fiberglass composite board to be bent from the inlet 4 into the cleaning box 2 and starts the motor 6. The motor 6 drives the conveyor rollers 7 to rotate. The conveyor rollers 7 are connected by belts, so they rotate simultaneously. The rotation of the conveyor rollers 7 drives the telescopic tubes 8, which are evenly fixed to their outer walls, to rotate as well. The suction cups 9, hinged to the other end of the telescopic tubes 8, rotate with the telescopic tubes 8. When the thermoplastic fiberglass composite board enters the cleaning box 2, the bottom of the board is in contact with the support rollers 5. When the suction cups 9 rotate, they contact the top of the board and, as they rotate, hold the board in place, squeezing and dragging it, causing it to move along the support rollers 5. When the thermoplastic fiberglass composite board moves, it passes between cleaning rollers 12. The outer wall of the cleaning rollers 12 is fitted with a cleaning sponge 13, which is in contact with the outer wall of the thermoplastic fiberglass composite board. As the thermoplastic fiberglass composite board moves, the cleaning sponge 13 wipes the outer wall of the thermoplastic fiberglass composite board, thereby removing the dust adhering to the outer wall of the thermoplastic fiberglass composite board. After wiping, the thermoplastic fiberglass composite board continues to move, leaving the cleaning box 2 from the discharge port 3 and entering the interior of the bending machine 1 for bending. This reduces the probability of defects appearing in the thermoplastic fiberglass composite board after bending due to residual impurities on the surface of the thermoplastic fiberglass composite board.

[0051] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
