Locking method and locking device for pressing type bottle cap

Abstract

The invention discloses a locking method and a locking device for a pressing type bottle cap. The locking method comprises the following steps of, applying pressure towards a bottle cap body to a pressing piece to enable the bottle cap body to be limited in the axial direction of the bottle cap body; and enabling the pressing piece to rotate relative to the bottle cap body in a pressed state to bein threaded connection with the bottle cap body until the torsion value of a torsion sensor to the bottle cap body reaches a preset torsion value. The locking device comprises a workbench, at least one pressing mechanism, and at least one driving mechanism, wherein a fixing base is arranged on the workbench; the pressing mechanisms are arranged right above a fixing seat, and each pressing mechanism comprises a pressing seat, a pressing part connected to the pressing seat in a sliding manner, and an elastic piece propped between the pressing seat and the pressing part; the driving mechanisms are arranged under the fixing seat, each driving mechanism is opposite to the corresponding pressing mechanism, and each driving mechanism comprises a driving motor and a torsion sensor which is connected with the driving motor and has a preset torsion value. By means of the locking device, the pressing piece and the bottle cap body can be effectively connected, and the assembling percent of pass is increased.

Description

technical field [0001] The invention relates to the field of bottle caps, in particular to a locking method and a locking device for a push-type bottle cap. Background technique [0002] Push-type bottle caps are generally used in packaging containers for liquid sprays, lotions, emulsions and other products. The movement of the piston is used to discharge the air in the liquid storage cylinder, resulting in a difference in air pressure inside and outside, so that the liquid is discharged from the liquid outlet pipe under the action of air pressure. [0003] The push-type bottle cap includes a bottle cap body connected with the bottle body and a nozzle assembly connected through the bottle cap body. The combination of the existing push-type bottle cap is to realize the assembly of the two by controlling the number of rotations of the spray head assembly in the bottle cap body. However, in the actual processing process, because the initial positions of the bottle cap body an...

AI Technical Summary

Problems solved by technology

However, in the actual processing process, because the initial positions of the bottle cap body and the nozzle assembly are different, after rotating the same number of turns, some can achieve an effective connection, but in many cases, the rotation will be too tight to cause The product is scrapped or the two fail to achieve effective connection, which increases the production cost of the enterprise
