Servo motor transmission for full-automatic steel plastic strip bundling machine

Abstract

The invention relates to the technical field of automatic machining mechanical equipment, and discloses a servo motor transmission for a full-automatic steel plastic strip bundling machine. The servomotor transmission comprises a shell, a first inner gear output shaft, a second inner gear output shaft, a planet gear, a first inner gear ring, a guide inner gear ring, a fixed gear disc, a duplex gear shaft, a planet gear shaft, a center shaft, a shell back cover and a servo motor; the shell is a cavity opened on one side; the shell back cover is arranged in the opened place of the shell; the fixed gear disc is arranged on the end surface, far from the shell, of the shell back cover; and the servo motor is arranged on the end surface, far from the shell, of the fixed gear disc. Pressure airis pressed into the shell from a first intake hole and a second intake hole in the shell to push the guide inner gear ring to different states; and under internal gear transmission in different states, the pneumatic adjustment of high / low-speed switching and the outputting of different rotating torques are realized, so that the manual adjustment is effectively saved, the operation is convenient, the cost is lower, and the vigorous popularization is deserved.

Description

technical field [0001] The invention relates to the technical field of automatic processing machinery and equipment, in particular to a servo motor transmission for a fully automatic steel-plastic strapping machine. Background technique [0002] With the development of society, the market demand for steel is increasing. The quality of steel bundling and packaging not only affects the sales, transportation and storage of steel, but also directly affects the maintenance of product quality. Steel bundling and packaging is the last step in steel production. The process, the form of bundling and the size of the bundling force directly affect the quality of the packaging.

[0002] With the development of society, the market demand for steel is increasing. The quality of steel bundling and packaging not only affects the sales, transportation and storage of steel, but also directly affects the maintenance of product quality. Steel bundling and packaging is the last step in steel production. The process, the form of bundling and the size of the bundling force directly affect the quality of the packaging. In the actual bundling process, the materials to be bundled are different, the specifications are different, and the characteristics are different. It is required that the tightening force of the strap should be suitable for the bundled objects. In addition, in the strapping conveying process of the automatic steel-plastic strapping machine, high-speed conveying and low-speed high-torque conveying must be used together to meet the functional requirements of fully automatic bundling. When the strapping machine wraps the strap The belt conveying process of the bundled objects is a high-speed and low-torque conveying process, and the process of tightening the straps to bind the bundled objects is a low-speed and high-torque conveying process. The motor of the existing automatic strapping machine is equipped with a fixed speed ratio reducer The machine-driven conveying strap is a single conveying method that cannot change the torque, which is not suitable for scientific and effective bundling. Some strapping machines use an air motor with a gearbox to drive the strapping method. Although there is a distinction between high and low speeds, due to It is a manual adjustment of the relative setting torque, which achieves a fixed value of the binding force. It is not convenient to quickly adjust the binding force according to the actual needs during use, and it cannot meet different objects to be bound.
