Description

Technical Field

[0001] The utility model relates to the technical field of glass fiber reinforced plastic production, in particular to a supporting device for glass fiber reinforced plastic production. Background Art

[0002] FRP is a composite material made of glass fiber and its products as reinforcements and a synthetic resin as a matrix. It boasts high strength, excellent corrosion resistance, and low cost. However, during FRP production, since manual support is not possible, a dedicated support device is required.

[0003] Chinese patent CN212859396U discloses a support device for glass fiber reinforced plastic production, including a bottom plate, one end of the top of the bottom plate is fixedly connected to a first fixed plate, the inside of the first fixed plate is rotatably connected to a first rotating tube, the outside of the first fixed plate is fixedly connected to a transmission box, the bottom of the transmission box is fixedly installed with a servo motor at one end away from the first fixed plate, the output shaft of the servo motor extends to the inside of the transmission box and is fixedly connected to a driving gear, and one end of the first rotating tube passes through the transmission box. The beneficial effects achieved by this utility model are: the utility model has a compact structure, simple and convenient operation, and strong practicality. By setting a clamping mechanism, it can clamp and fix round tube glass fiber reinforced plastics of different diameters, and at the same time, in conjunction with the gear transmission, it can drive the glass fiber reinforced plastics to rotate freely, thereby facilitating better processing of different positions on the surface of the round tube glass fiber reinforced plastics, thereby greatly improving the production efficiency of glass fiber reinforced plastics. However, there are still defects that can be improved:

[0004] 1. In this utility model, a first fixing plate and a second fixing plate are fixedly connected to the top of the base plate to serve as support members. However, since both the first fixing plate and the second fixing plate are fixedly connected to the base plate, only glass fiber reinforced plastics of a fixed size can be clamped. This greatly limits the applicability of the device and reduces the economic benefits for users.

[0005] 2. In this utility model, the first rotating barrel is indirectly driven to rotate by a servo motor, but the transmission relationship between the driving wheel and the driven wheel is not self-locking, which can easily lead to the rotation of the glass fiber reinforced plastic due to uneven distribution of the center of gravity when processing the glass fiber reinforced plastic, thereby adversely affecting the precision processing of the glass fiber reinforced plastic, and ultimately generating more waste and causing economic losses.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] The working principle of this utility model is as follows Figure 1-Figure 5 As shown, a support device for glass fiber reinforced plastic production includes a base 1. First, connecting plates 2 are slidably connected to both sides of the top of the base 1. The connecting plates 2 on both sides can move relative to or away from each other. Then, rotating holes 4 are opened on the upper parts of the adjacent sides of the connecting plates 2 on both sides. The rotating holes 4 on both sides are bearing-connected with rotating shafts 5, so that the rotating shafts 5 can only rotate in the rotating holes 4 and will not move laterally in the rotating holes 4. Rotating devices 7 are provided on the separated sides of the rotating shafts 5 on both sides. The rotating devices 7 allow the rotating shafts 5 to rotate automatically. At the same time, clamping devices 6 are provided on the adjacent sides of the rotating shafts 5 on both sides. Finally, in order to fix the connecting plates 2 after they move, telescopic devices 3 are provided on the lower parts of the separated sides of the connecting plates 2 on both sides.

[0032] Here, the clamping device 6 includes a rotating plate 601 fixedly connected to the rotating shaft 5, and the rotating plate 601 is located on the side of the rotating shaft 5 away from the telescopic device 3. First, a fixed block 1 602 is fixedly connected to the upper part of the rotating plate 601 away from the rotating shaft 5, and a bolt 604 is threadedly connected to the fixed block 1 602, and then the bottom end of the bolt 604 passes through the fixed block 1 602 and is rotatably connected to the pressure plate 605. It should be noted that the side of the pressure plate 605 close to the telescopic device 3 is also slidably connected to the rotating plate 601. The effect achieved so far is that when the bolt 604 rotates, the bolt 604 will push the pressure plate 605 to move downward, and then a fixed block 2 603 is provided below the pressure plate 605, where the fixed block 2 603 is fixedly connected to the rotating plate 601, and finally, a number of anti-sliding blocks 606 are fixedly connected to the adjacent sides of the fixed block 2 603 and the pressure plate 605, and the anti-sliding blocks 606 are used to reduce the sliding of the fiberglass reinforced plastic.

[0033] The above-mentioned structures together constitute the general appearance structure of the support device for glass fiber reinforced plastic production of the present invention.

[0034] In order to further explain the specific working principle of the support device for glass fiber reinforced plastic production of the present invention, the rotating device 7 includes a worm gear 701 fixedly connected to the side of the rotating shaft 5 away from the clamping device 6, and then a protective box 705 is fixedly connected to the upper part of the side of the connecting plate 2 away from the clamping device 6. It should be noted that the worm gear 701 is located in the protective box 705, and then a rotating frame 704 is fixedly connected to the rear part of the bottom wall of the protective box 705, and the front end of the rotating frame 704 is rotatably connected to the worm 702, where the worm 702 is meshed with the worm gear 701, and then a servo motor 703 is fixedly connected to the front end of the worm 702. It should be noted that the servo motor 703 has a self-locking function, and the servo motor 703 is fixedly connected to the front part of the bottom wall of the protective box 705 by providing a motor seat 706.

[0035] The technical effect achieved by the technical solution composed of the above-mentioned technical features is: when it is necessary to control the rotation of the rotating shaft 5, the servo motor 703 is electrically driven, and then the output shaft of the servo motor 703 will drive the worm 702 to rotate together. When the worm 702 rotates on the rotating frame 704, it will also drive the worm wheel 701 engaged with it to rotate together. When the worm wheel 701 rotates, the rotating shaft 5 fixedly connected to the worm wheel 701 will rotate together.

[0036] In order to further explain the specific working principle of the support device for glass fiber reinforced plastic production of the present invention, the telescopic device 3 includes a shell 301 and a telescopic block 303 located below the rotating device 7. Here, the telescopic block 303 is slidably connected to the shell 301. The side of the telescopic block 303 close to the rotating device 7 is fixedly connected to the connecting plate 2, and the shell 301 is fixedly connected to the base 1. In order to fix the telescopic block 303 after it is moved to the specified position, a plurality of horizontally arranged positioning grooves 304 are first opened on the telescopic block 303. At the same time, a plurality of horizontally arranged positioning grooves 304 are opened on the top of the shell 301. A positioning hole 302 is provided on one side of the end close to the connecting plate 2 for use with the positioning groove 304. Here, the positioning hole 302 and the positioning groove 304 are of the same size, and then a positioning shaft 305 is inserted into the positioning groove 304. It should be noted here that the middle part of the positioning shaft 305 is inserted into the positioning hole 302, and a connecting block 306 is fixedly connected to the top of the positioning shaft 305. In order to allow the positioning shaft 305 to automatically reset, a shock-absorbing spring 307 is provided around the outer periphery of the positioning shaft 305, and the top and bottom ends of the shock-absorbing spring 307 are fixedly connected to the connecting block 306 and the outer shell 301 respectively.

[0037] The technical effect achieved by the technical solution composed of the above technical features is: when the position of the connecting plate 2 needs to be changed, the connecting block 306 is first lifted upward, and then the connecting block 306 will drive the positioning shaft 305 to move upward together, and at the same time the connecting block 306 will also stretch the shock-absorbing spring 307. When the positioning shaft 305 is completely moved out of the positioning groove 304, the positioning shaft 305 will no longer limit the position of the telescopic block 303. Then the user moves the telescopic block 303 to the specified position, and the telescopic block 303 can drive the connecting plate 2 to move to the specified position. Finally, the user releases the connecting block 306, and the shock-absorbing spring 307 can indirectly drive the positioning shaft 305 to return to its original position, and the lower part of the positioning shaft 305 enters the next positioning groove 304, so that the position of the telescopic block 303 is fixed again.
