DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 6 The utility model provides a technical solution: a correction device for prepreg production, comprising a base 1, the bottom of the base 1 is supported by legs 2, and a U-shaped frame 3 is fixedly connected to the top of one side of the base 1, wherein:

[0025] A hydraulic rod 4 is symmetrically installed on the top of the U-shaped frame 3, and an extrusion plate 5 is installed on the telescopic end of the hydraulic rod 4 located in the U-shaped frame 3. A storage plate 6 is installed on the top of the base 1 corresponding to the extrusion plate 5, and a heating resistor 7 is installed in the storage plate 6. A loading trough 8 is penetrated on the side of the base 1 close to the U-shaped frame 3, and a lifting frame 9 is arranged below the base 1 corresponding to the loading trough 8. Workpieces 10 are stacked on the lifting frame 9. A bracket 11 is fixedly connected to the top of one end of the base 1 close to the loading trough 8, and a first gear rod 12 is penetrated on the bracket 11;

[0026] A push plate 13 is fixedly connected to one end of the first gear rod 12 close to the workpiece 10, a first transmission gear 14 meshing with the first gear rod 12 is rotatably connected to the top of the base 1, a second transmission gear 15 is fixedly connected to the shaft end of the first transmission gear 14, a second gear rod 16 is fixedly connected to one side of the extrusion plate 5 close to the second transmission gear 15, the second gear rod 16 meshes with the second transmission gear 15, a gear rod slot 17 runs through the position of the base 1 corresponding to the second gear rod 16, and the lifting frame 9 is controlled to lift and lower by an electric lifting mechanism;

[0027] When the semi-cured sheet needs to be corrected, the extrusion plate 5 is controlled to move downward by the hydraulic rod 4, and the semi-cured sheet is extruded by the extrusion plate 5 and the storage plate 6. At the same time, the storage plate 6 heats the semi-cured sheet through the heating resistor 7 to correct the deformed semi-cured sheet. When the hydraulic rod 4 controls the extrusion plate 5 to rise and fall, the extrusion plate 5 drives the second gear rod 16 to rise and fall synchronously, the second gear rod 16 drives the second transmission gear 15 to rotate, and the second transmission gear 15 drives the first transmission gear 14 to rotate. The first transmission gear 14 drives the first gear rod 12 and the push plate 13 to move horizontally through meshing, so that when the extrusion plate 5 moves downward, the push plate 13 moves away from the storage plate 6, and the extrusion plate 5 moves upward. When resetting, the push plate 13 moves toward the placement plate 6, pushes the workpiece 10 (prepreg) at the top of the lifting frame 9 onto the placement plate 6, pushes the workpiece 10 that has been calibrated on the placement plate 6 down, and makes the calibrated workpiece 10 fall onto the conveying device. After the push plate 13 is reset, the lifting frame 9 is controlled to rise a certain distance by the electric lifting mechanism, and the height of the rising distance is consistent with the thickness of the workpiece 10. Through the correction device for prepreg production, the extrusion plate 5 can be raised to calibrate the workpiece 10 while the extrusion plate 5 is raised and lowered, and the pushing structure is driven synchronously to automatically load the workpiece 10, thereby avoiding manual loading, reducing the labor tasks of the staff and improving work efficiency.

[0028] See also Figures 1 to 6 The bottom of the top of the workpiece 10 is at the same horizontal height as the top of the placement plate 6. The second gear rod 16 is L-shaped, and the second gear rod 16 is meshed with the side of the second transmission gear 15 away from the extrusion plate 5. When the push plate 13 pushes the workpiece 10, the workpiece 10 can be smoothly pushed onto the placement plate 6 to avoid jamming.

[0029] See also Figures 1 to 6The electric lifting mechanism includes a third gear rod 18, and the third gear rod 18 is symmetrically fixedly connected to the bottom of both sides of the base 1 near the loading trough 8. The third transmission gear 19 meshing with the third gear rod 18 is rotatably connected to the bottom of the side of the lifting frame 9. The base 1 is symmetrically fixedly connected to the bottom of the other two sides near the loading trough 8. A guide frame 20 is symmetrically fixedly connected to the bottom of the guide frame 20. A guide groove 21 is opened inside the guide frame 20. A guide block 22 is fixedly connected to the side of the lifting frame 9 corresponding to the guide groove 21. The shaft end of the third transmission gear 19 is fixedly connected to a first reversing gear 23. The bottom of the lifting frame 9 is rotatably connected to a rotating shaft 24, and the shaft end of the rotating shaft 24 is fixedly connected to a second reversing gear 25 meshing with the first reversing gear 23. A worm gear 26 is fixedly connected to the middle of the rotating shaft 24. A servo motor 27 is installed inside the lifting frame 9, and the shaft end of the servo motor 27 is fixedly connected to a second reversing gear 25 meshing with the first reversing gear 23. The meshing worm 28 and the outer dimensions of the guide block 22 are consistent with the inner dimensions of the guide groove 21, and the guide groove 21 and the guide block 22 form a guide structure. When the servo motor 27 is working, it drives the worm 28 to rotate, and drives the rotating shaft 24 to rotate through the one-way transmission formed by the worm 28 and the worm wheel 26. The rotating shaft 24 drives the first reversing gear 23 to rotate through the second reversing gear 25, and the first reversing gear 23 drives the third transmission gear 19 to rotate, so that the servo motor 27 drives the third transmission gears 19 on both sides to rotate in opposite directions at the same time. The third transmission gear 19 drives the lifting frame 9 to lift and lower by meshing with the third gear rod 18. When the lifting frame 9 is lifted and lowered, the guide structure formed by the guide groove 21 and the guide block 22 avoids deviation during lifting and lowering, so that the lifting frame 9 can be lifted and lowered vertically, thereby facilitating the auxiliary pushing structure to complete automatic loading.

[0030] Working principle: This is a correction device for prepreg production. When the prepreg needs to be corrected, the hydraulic rod 4 controls the extrusion plate 5 to move downward, and the prepreg is extruded by the extrusion plate 5 and the placement plate 6. At the same time, the placement plate 6 heats the prepreg through the heating resistor 7 to correct the deformed prepreg. When the hydraulic rod 4 controls the extrusion plate 5 to rise and fall, the extrusion plate 5 drives the second gear rod 16 to rise and fall synchronously, the second gear rod 16 drives the second transmission gear 15 to rotate, and the second transmission gear 15 drives the first transmission gear 15 to rotate. The movable gear 14 rotates, and the first transmission gear 14 drives the first gear rod 12 and the push plate 13 to move horizontally through meshing, so that when the extrusion plate 5 moves downward, the push plate 13 moves away from the placement plate 6. When the extrusion plate 5 is reset upward, the push plate 13 moves toward the placement plate 6, pushing the workpiece 10 (prepreg) at the top of the lifting frame 9 onto the placement plate 6, and pushing the workpiece 10 that has been calibrated on the placement plate 6 down, so that the calibrated workpiece 10 falls onto the conveying device, and after the push plate 13 is reset, the workpiece 10 is pushed back and then pushed back. The electric lifting mechanism controls the lifting frame 9 to rise a certain distance, and the height of the rising distance is consistent with the thickness of the workpiece 10. Through the correction device for prepreg production, the extrusion plate 5 can be lifted to correct the workpiece 10, and the extrusion plate 5 can synchronously drive the pusher structure to automatically load the workpiece 10, avoiding manual loading, reducing the labor tasks of the staff and improving work efficiency. When the servo motor 27 is working, it drives the worm 28 to rotate, and drives the rotating shaft 24 to rotate through the one-way transmission formed by the worm 28 and the worm wheel 26. The rotating shaft 24 drives the first reversing gear 23 to rotate through the second reversing gear 25, and the first reversing gear 23 drives the third transmission gear 19 to rotate, so that the servo motor 27 drives the third transmission gears 19 on both sides to rotate in opposite directions at the same time. The third transmission gear 19 drives the lifting frame 9 to rise and fall by meshing with the third gear rod 18. When the lifting frame 9 is lifted and lowered, the guide structure formed by the guide groove 21 and the guide block 22 avoids deviation during lifting, so that the lifting frame 9 can be lifted and lowered vertically, thereby facilitating the auxiliary pusher structure to complete automatic loading.
