Description

Technical Field

[0001] This utility model discloses an insulating paper bending and flattening mechanism, which relates to the field of insulating paper bending machine technology. Background Technology

[0002] An insulating paper bending machine is a specialized piece of machinery used to process insulating paper (commonly used in electrical equipment, transformers, motors, etc.). Its main function is to process insulating paper into desired shapes, typically through bending, rolling, or cutting. Insulating paper possesses a certain degree of elasticity and high-temperature resistance, making it suitable for electrical insulation. Therefore, the bending machine must carefully maintain the material's physical properties and stability during processing. Depending on customer needs, the machine can bend insulating paper into specific angles or curves, commonly used to create the shapes of internal insulating materials in motors, power tools, etc. The bent insulating paper usually needs to be cut to appropriate sizes; the cutting function helps the machine accurately control the length after bending. In some applications, the insulating paper may require special shaping, such as rolling it into a tube or other special shapes. The bending machine can adjust the shape according to different dies. Some modern bending machines not only bend but also perform various processing steps on the insulating paper, such as heating and gluing, to further improve its performance.

[0003] When the insulating paper bending machine is feeding and bending the paper, the tail end of the paper may lift up after the pressure head presses down on it, causing a slight positional shift. This results in a decrease in bending accuracy and an increase in product defects. After the insulating paper is fed into the feeding platform, its surface is bent as it is fed from the rollers, which may affect the bending effect. Therefore, an insulating paper bending and flattening mechanism is needed to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide an insulating paper bending and flattening mechanism to achieve the effect of flattening the surface of the conveyed insulating paper raw material and reducing the offset.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an insulating paper bending and flattening mechanism, comprising a base and an upper module, characterized in that: a workbench is installed on the base, a bending table is installed below the upper module, and a bending table is installed above the workbench; a transmission cylinder is installed below the upper module, a pressure cylinder is installed below the upper module, a bending machine is installed above the upper module, a limiting plate is installed on the side of the bending machine, and a pressure roller is installed on the workbench.

[0006] Preferably, the transmission cylinder is driven by a motor.

[0007] Preferably, the bending machine is a three-quarter circle, and one corner of the bending machine is connected to the upper surface of the limiting plate.

[0008] Preferably, a connecting block is rotatably mounted on the side of the pressure cylinder, a telescopic rod is mounted on the connecting block, a spring is mounted on the outside of the telescopic rod, and the telescopic rod is mounted on the upper module. The structure of the pressure cylinder is the same as that of the transmission cylinder.

[0009] Preferably, a bracket is rotatably mounted on the pressure roller, and the bracket is symmetrically rotatably mounted on the worktable. A torsion spring is provided at the connection between the bracket and the worktable.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the raw material paper enters from the workbench, and a roll is provided at the raw material inlet of the workbench. The raw material paper enters the raw material inlet from the roll. The raw material paper has a certain curvature when it first enters the workbench, and then enters the pressure roller. The pressure roller is an adaptive pressing mechanism. The pressure roller will lift and flatten the raw material paper as it enters. Then, it enters the transmission cylinder under the push of the roll. The transmission cylinder can rotate continuously under the drive of the motor, and it can move up and down adaptively. The raw material paper continues to be transmitted by the transmission cylinder and can be pressed. Then, it enters the pressure cylinder. The main function of the pressure cylinder is to press the raw material paper when it is bent in the next step, so that its position is not easy to move during the pressing. This achieves the effect of flattening the surface of the guided insulating paper raw material and reducing the amount of offset. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Specific implementation examples:

[0017] like Figure 1As shown, an insulating paper bending and flattening mechanism includes a base 1 and an upper module 3. A workbench 2 is installed on the base 1, a bending table 4 is installed below the upper module 3, and a bending table 4 is installed above the workbench 2.

[0018] The base 1 is fixedly mounted on the bending machine. The upper worktable 2 is used for guiding and holding the raw materials. The bending table 4 is the main working component used for pressing down and bending the insulating paper. The upper module 3 is fixedly mounted to the bending table 4. The upper module 3 is mainly controlled by a motor. The upper module 3 is equipped with a motor and control lever that can control the bending table 4. The worktable 2 is equipped with a pressure roller 5.

[0019] like Figure 2 As shown, a raw material paper 21 is provided above the workbench 2, a pressure roller 5 is installed above the workbench 2 to hold the raw material, a transmission cylinder 6 is installed below the upper module 3, the transmission cylinder 6 is driven by a motor, a pressure cylinder 7 is installed below the upper module 3, a bending machine 8 is installed above the upper module 3, and a limiting plate 9 is installed on the side of the bending machine 8.

[0020] Raw material paper 21 enters from workbench 2. Workbench 2 is equipped with a roll at the raw material inlet. Raw material paper 21 enters the raw material inlet from the roll. The raw material paper 21 has a certain curvature when it first enters workbench 2. Then it enters pressure roller 5. Pressure roller 5 is an adaptive pressing mechanism. Pressure roller 5 will lift and flatten raw material paper 21 as it enters. Then it enters transmission roller 6 under the push of the roll. Transmission roller 6 can rotate continuously under the drive of motor and can move up and down adaptively. Raw material paper 21 continues to be transmitted by transmission roller 6 and can be pressed. Then it enters pressure roller 7. The main function of pressure roller 7 is to press the raw material paper 21 when it is bent in the next step, so that its position is not easy to move during the pressing.

[0021] The bending machine platform 8 is a three-quarter circle, and one corner of the bending machine platform 8 abuts against the upper surface of the limiting plate 9;

[0022] When bending, the limiting plate 9 and the bending machine 8 move downward simultaneously under the control mechanism on the upper module 3. When the limiting plate 9 moves downward until it touches the raw material paper 21, the limiting plate 9 is provided with a telescopic rod 71. The telescopic rod 71 moves upward and extends, and the inner surface of the limiting plate 9 touches the sharp corner of the bending machine 8, causing the bending machine 8 to rotate clockwise. The other corner of the three-quarter circle is used to bend the raw material paper 21.

[0023] A connecting block 73 is rotatably mounted on the side of the pressure cylinder 7. A telescopic rod 71 is mounted on the connecting block 73. A spring 72 is mounted on the outside of the telescopic rod 71. The telescopic rod 71 is mounted on the upper module 3. The structure of the pressure cylinder 7 is the same as that of the transmission cylinder 6.

[0024] When the pressure cylinder 7 and the transmission cylinder 6 are working, they can rise and fall adaptively according to the thickness of the raw material paper 21 passing through, so as to better press the raw material paper 21. When the raw material paper 21 enters, the transmission cylinder 6 is adaptively adjusted under the extension and retraction of the spring 72 and the telescopic rod 71. The working principle of the pressure cylinder 7 is the same as that of the transmission cylinder 6, and will not be elaborated here. The pressure cylinder 7 can rotate and press the raw material paper 21 as it is conveyed.

[0025] A bracket 51 is rotatably mounted on the pressure roller 5. The bracket 51 is symmetrically rotatably mounted on the worktable 2. A torsion spring (not shown in the figure) is provided at the connection between the bracket 51 and the worktable 2.

[0026] The pressure roller 5 can move up and down adaptively when the raw material paper 21 enters, so as to achieve adaptive initial pressing of the raw material paper 21;

[0027] In summary, the raw material paper 21 enters from the workbench 2. A roll is provided at the raw material inlet of the workbench 2. The raw material paper 21 enters the raw material inlet from the roll. The raw material paper 21 has a certain curvature when it first enters the workbench 2. Then it enters the pressure roller 5. The pressure roller 5 is an adaptive pressing mechanism. The pressure roller 5 will lift and flatten the raw material paper 21 as it enters. Then it is pushed into the transmission cylinder 6 by the roll. The transmission cylinder 6 can rotate continuously under the drive of the motor and can move up and down adaptively. The raw material paper 21 continues to be transmitted by the transmission cylinder 6 and can be pressed. Then it enters the pressure cylinder 7. The main function of the pressure cylinder 7 is to press the raw material paper 21 when it is bent in the next step, so that its position is not easy to move during the pressing. This achieves the effect of flattening the surface of the guided insulating paper raw material and reducing the amount of offset.
