Flexible pneumatic bottle cap clamping part

Abstract

A flexible pneumatic bottle cap clamping part comprises a capping threaded sleeve, an elastic clamp ring, a rotating seat cover, a gland core, a mandrel seal ring, a tightening nut, an air chamber and an air inlet. The flexible pneumatic bottle cap clamping part is characterized in that pressure air enters the air chamber from the air inlet to force an inner side of the elastic clamp ring to pressure the bottle cap for clamping; due to the fact pressure of the pressure air is adjustable, the size of the clamping force to the bottle cap can be changed; with the bottle cap to be flexibly clamped through the inner side of the elastic clamp ring, the elastic clamp ring does no damage to the bottle cap and leaves no clamp marks during the clamping and capping; when the bottle cap is tightened, the air chamber is made to be communicated with outside, and after the loss of the pressure, the bottle cap is automatically loosened. The flexible pneumatic bottle cap clamping part has the advantages that cover taking without resistance, flexible pneumatic clamping and loosening are achieved, operation is stable and reliable, and clamping force is adjustable. Furthermore, the flexible pneumatic bottle cap clamping part can support the use of a pneumatic motor or a servo motor to be served as a cover taking and capping part of a capper.

Description

Technical field: [0001] The invention relates to a liquid filling device, in particular to a bottle capping machine, and more specifically to a capping device on the capping machine. Background technique: [0002] The existing capping machines are equipped with a cap unscrambling machine and a cap feeder. The cap unscrambling machine straightens the caps and sends them to the bottle mouth through the cap feeder, and then the capping machine performs capping. The capping method has a belt type capping And fixed mechanical three-jaw swivel head. Although the belt screw cap can flexibly rotate the bottle cap without damaging the bottle cap, but with the elongation of the belt, the clamping force of the belt on the bottle cap is unstable and uncontrollable. If the screw is not tight or the screw is too tight, the bottle cap will be cracked, and the torque of the screw cap cannot be controlled. The fixed mechanical three-jaw rotary head is not only difficult to control the cap ...

AI Technical Summary

Problems solved by technology

Although the belt screw cap can flexibly rotate the bottle cap without damaging the bottle cap, but with the elongation of the belt, the clamping force of the belt on the bottle cap is unstable and uncontrollable. If the screw is not tight or the screw is too tight, the bottle cap will be cracked, and the torque of the screw cap cannot be controlled.

The fixed mechanical three-jaw rotary head is not only difficult to control the clamping force, but also the steel chuck will cause great damage to the bottle cap. After the bottle cap is tightened, there will be pinch marks on the bottle cap, and the capping torque cannot be controlled.
