Servo bottle cap screwing mechanism

Abstract

The invention relates to a servo bottle cap screwing mechanism in the technical field of packaging machinery, which comprises a cap screwing head, a waste cap withdrawing mechanism, an idler wheel mechanism, base blocks, a servomotor, a connecting support and a motor control system, wherein, the cap screwing head, the idler wheel mechanism, the servomotor and the connecting support are arranged on the base blocks, the motor control system controls the servomotor to rotate at certain rotating speed and torque, and the generated dynamic power is transferred to the cap screwing head by the idler wheel mechanism, so as to cause the cap screwing head to rotate along with the servomotor; the connecting support is connected with a lifting guide rod to drive the base blocks to raise and fall periodically, and the height of the waste cap withdrawing mechanism is unchanged, and the waste cap withdrawing mechanism is arranged at a cap screwing machine. Under the germfree condition, the entire bottle cap screwing mechanism is lubrication free, has no leakage, is convenient for frequent rinsing and disinfection; the cap screwing torque is controlled by computer, the cap screwing mechanism is driven by servomotor and has large adjustable range; and besides, the working torque, the cap screwing speed, and the like, of the single cap screwing mechanism can be displayed, and the cap screwing mechanism can automatically discharge waste or abnormal caps.

Description

technical field [0001] The invention relates to a device in the technical field of packaging machinery, in particular to a servo-type bottle cap screwing mechanism. Background technique [0002] In the aseptic cold filling production process of the filling bottle (hereinafter referred to as PET bottle) that requires precise torque control and system lubrication-free maintenance, after the bottle is rinsed and filled, it is sent to the capping machine to cap the bottle mouth. The capping mechanism of the capping machine picks up the sterilized bottle cap smoothly, runs it to the top of the bottle mouth, rotates at a certain speed, and presses down at the same time. After reaching a certain torque, the rotation stops, and the bottle mouth has been sealed. The workflow of aseptic cold filling has special requirements for the equipment to be free from lubrication and easy to clean and disinfect. [0003] The capping mechanism is the main component of the capping machine, which ...

AI Technical Summary

Problems solved by technology

Mechanical adjustment of speed and torque is not conducive to flexible production and automatic operation; there is a possibility of leakage in lubrication, which is not conducive to hygiene and safety in aseptic cold filling production; it cannot be removed in the case of waste caps, which is not conducive to efficient operation of the production line
