Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rotational molding equipment, and particularly relates to a spindle structure of a rotational molding equipment. Background Art
[0002] Rotational molding, also known as rotational molding, rotational forming, rotary forming, etc., is a method for forming hollow thermoplastic plastics. In this method, plastic raw materials are first added into a mold, and then the mold is placed in an oven and rotated continuously along two perpendicular axes and heated. Under the action of gravity and heat energy, the plastic raw materials in the mold gradually and evenly coat, melt and adhere to the entire surface of the mold cavity, forming the required shape, and then cooled and shaped into a product.
[0003] The existing mold is driven by rolling discs installed at both ends to rotate in the oven. As the rolling discs rotate, the plastic raw materials in the mold gradually melt and evenly coat on the surface of the mold under the action of gravity and friction. However, in the above processing process, two groups of motors are required to drive the rolling discs at one end of two groups of main shafts to rotate, and the plastic raw materials in the mold are processed. Since the two groups of motors operate simultaneously, more electric energy will be consumed, resulting in an increase in the energy consumption of the entire rotational molding process, and further increasing the production cost. Content of the Utility Model
[0004] The purpose of the utility model is to provide a spindle structure of a rotational molding equipment to solve the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A spindle structure of a rotational molding equipment, comprising:
[0006] A rotating cylinder, one side of the rotating cylinder is connected with a support rod, and there is a mounting plate on one side of the rotating cylinder. The surface of the mounting plate is rotatably connected with a main shaft, and the other side of the surface of the mounting plate is connected with a servo motor. The output shaft of the servo motor is connected with the main shaft. The middle part of the rotating cylinder is rotatably connected with a rotating shaft, and both ends of the rotating shaft are connected with a first rotating frame and a second rotating frame. A bevel gear ring is connected to the surface of the first rotating frame, and a bevel gear is connected to one end of the main shaft. Through the meshing of the bevel gear and the bevel gear ring, when the main shaft rotates, the bevel gear can drive the bevel gear ring to rotate, realizing the synchronous rotation of the first rotating frame and the second rotating frame.
[0007] Preferably, a bearing is provided at the connection between the rotating shaft and the rotating cylinder, and the other end of the bevel gear is rotatably connected with the rotating cylinder.
[0008] Preferably, support plates and L-shaped plates are connected to the surfaces of the first rotating frame and the second rotating frame, and a plurality of first rollers are rotatably connected between the support plates and the L-shaped plates.
[0009] Preferably, second rollers are rotatably connected to the front ends of the first rotating frame and the second rotating frame through rotating brackets.
[0010] Preferably, one end of the support rod is connected with a fixing plate.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: By fixing the mounting plate on the surface of the processing equipment and also fixing the fixing plate at one end of the support rod to the processing equipment, the working stability of the equipment can be enhanced. When the servo motor is started to work, the output shaft of the servo motor drives the main shaft to rotate. One end of the main shaft drives the bevel gear to rotate, and drives the engaged bevel gear ring to rotate through the bevel gear, and drives the first rotating frame to rotate through the bevel gear ring. Thus, the rotating first rotating frame drives the rotating shaft to rotate, and the rotating rotating shaft drives the second rotating frame to rotate, so that one servo motor can drive the first rotating frame and the second rotating frame to rotate simultaneously in the up and down directions, thereby greatly reducing the energy consumption and production cost.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0016] The present utility model provides a main shaft structure of a rotational molding device as Figure 1-2 shown, including:
[0017] Rotate the rotating cylinder 1. One side of the rotating cylinder 1 is connected with a support rod 2. There is a mounting plate 3 on one side of the rotating cylinder 1. A main shaft 4 is rotatably connected to the surface of the mounting plate 3, and a servo motor 5 is connected to the other side of the surface of the mounting plate 3. The output shaft of the servo motor 5 is connected to the main shaft 4. A rotating shaft 6 is rotatably connected to the middle of the rotating cylinder 1, and both ends of the rotating shaft 6 are connected with a first rotating frame 7 and a second rotating frame 8. A bevel gear ring 9 is connected to the surface of the first rotating frame 7. One end of the main shaft 4 is connected with a bevel gear 10. Through the engagement of the bevel gear 10 and the bevel gear ring 9, when the main shaft 4 rotates, the bevel gear 10 can drive the bevel gear ring 9 to rotate, so as to realize the synchronous rotation of the first rotating frame 7 and the second rotating frame 8.
[0018] A bearing 11 is provided at the connection between the rotating shaft 6 and the rotating cylinder 1. The other end of the bevel gear 10 is rotatably connected to the rotating cylinder 1. The bearing 11 can reduce the wear of the rotating cylinder 1 when the rotating shaft 6 rotates in the rotating cylinder 1.
[0019] Support plates 12 and L-shaped plates 13 are connected to the surfaces of the first rotating frame 7 and the second rotating frame 8. A number of first rollers 14 are rotatably connected between the support plates 12 and the L-shaped plates 13. The front ends of the first rotating frame 7 and the second rotating frame 8 are both rotatably connected with second rollers 16 through rotating brackets 15. When the first rotating frame 7 and the second rotating frame 8 rotate, they can drive the first rollers 14 and the second rollers 16 to rotate, thereby assisting the rotation of the first rotating frame 7 and the second rotating frame 8 and reducing wear.
[0020] One end of the support rod 2 is connected with a fixing plate 17. The fixing plate 17 at one end of the support rod 2 is also fixed to the processing equipment, so as to enhance the working stability of the equipment.
[0021] For the main shaft structure of this rotational molding equipment, by fixing the mounting plate 3 on the surface of the processing equipment and also fixing the fixing plate 17 at one end of the support rod 2 to the processing equipment, the working stability of the equipment can be enhanced. Start the servo motor 5 to work. The output shaft of the servo motor 5 drives the main shaft 4 to rotate. One end of the main shaft 4 drives the bevel gear 10 to rotate, and drives the engaged bevel gear ring 9 to rotate through the bevel gear 10, and drives the first rotating frame 7 to rotate through the bevel gear ring 9. Thus, the rotating first rotating frame 7 drives the rotating shaft 6 to rotate, and the rotating rotating shaft 6 drives the second rotating frame 8 to rotate, so as to realize that one servo motor 5 can drive the first rotating frame 7 and the second rotating frame 8 to rotate simultaneously in the upper and lower directions. And when the first rotating frame 7 and the second rotating frame 8 rotate, they can drive the first rollers 14 and the second rollers 16 to rotate, thereby assisting the rotation of the first rotating frame 7 and the second rotating frame 8 and reducing wear, thus greatly reducing energy consumption and production costs.
