[0030] The structure of this embodiment mainly consists of a main fixed module, a swing arm rotation module driven by a cylinder, and a pressure roller module with an automatic adjustment function. The main fixed module is designed to be stably installed on the winding device to ensure the stability and reliability of the overall structure. Driven by the cylinder, the swing arm swings around the rotating shaft, so that the pressure roller can be smoothly pressed down onto the material roll. A universal ball is configured at the roller shaft of the pressure roller, and a universal ball is configured on the left and right in the long hole of the support arm. Springs are configured up and down, so that the roller shaft of the pressure roller can slide freely up and down in the support arm, thereby ensuring that the pressure roller can adjust itself with the pole piece during the winding process, so as to better ensure that the pressure applied by the pressure roller on the material roll is consistent. The pressure roller with automatic adjustment function, as the core component of this patent, better ensures that the force applied by the pressure roller on the pole piece is consistent through the self-adjustment at the shaft ends on both sides, thereby greatly improving the winding efficiency and product quality. This patent realizes the automatic adjustment of the winding pressure roller through innovative structural design and the cooperation of the cylinder and the swing arm, which provides an efficient and stable solution for the quality and efficiency of winding and the winding of material rolls in related industries.
[0031] The working principle is: This patent relates to the working principle of the automatic adjustment device for the pressure roller, and its core components include a main fixed module, a swing arm telescopic module driven by a cylinder, and a pressure roller module with automatic adjustment function.
[0032] The main fixing module consists of a main fixing plate and a connecting beam. The main fixing plate is firmly installed on the winding structure, and the connecting beam serves as a support for the left and right fixing plates, so that the entire roller structure can be stably installed on the winding equipment, ensuring the stable operation of the roller whether it is stationary or in the working process.
[0033] The swing arm rotary module driven by the cylinder consists of the cylinder, the front and rear connecting seats of the cylinder, the swing arm, the seat bearing, the rotary shaft and the connecting beam. The cylinder is fixed on the main fixed plate through the rear connecting seat, and connected to the swing arm through the front connecting seat. The seat bearing is fixed on the main fixed plate and connected to the roller swing arm through the rotary shaft. The swing arm rotates around the rotary shaft under the configuration of the seat bearing through the ejection and retraction of the cylinder. The connecting beam connects the left and right swing arms, serving as the main support of the swing arm rotary module, so that the swing arm runs smoothly during the movement.
[0034] The pressure roller module with automatic adjustment function consists of a pressure roller, a roller shaft, a support arm, an embedded universal ball, a hexagonal head external thread universal ball, a rectangular spring and a swing arm end cover. The support arm is connected to the swing arm by bolts. The left and right ends of the pressure roller shaft are respectively installed in the long holes of the support arm. The left and right sides of the long hole of the support arm are respectively installed with embedded universal balls to fix the roller shaft in the left and right directions. The swing arm end cover is installed on the outside of the support arm to press the roller shaft to prevent the pressure roller from moving in the front and back directions. A rectangular spring is installed in the up and down directions, and a hexagonal head external thread universal ball is installed on the end face of the roller shaft. Through such an automatically adjustable module, the roller shaft will not move in the left and right and front and back directions, and can move in the up and down directions, so that the pressure roller and the material roll pole piece fit more closely, and the pressure applied to each part of the pole piece remains consistent.
