Conveying and clamping mechanism for PET bottles

Abstract

The invention discloses a transmission clamping mechanism for PET bottles. Includes mounting plate, lower base plate, short arm pin, short arm pin, short clamp arm, long clamp arm, drive pin, short arm support post and long arm support post, inner side walls of short clamp arm, and long clamp An arc-shaped opening is respectively opened on the inner side wall of the holding arm, and the two arc-shaped openings jointly form a driving pin positioning hole, and a driving pin is connected in the driving pin positioning hole; the long clamping arm and the lower base plate A long-arm support column and a short-arm support column are correspondingly arranged on the top; a clamping arm opening and closing elastic mechanism is arranged between the short-arm support column and the long-arm support column. The invention adopts the caliper as the clamping mechanism, which has low wear rate and avoids the problem that the mouth of the beverage bottle cannot be clamped; it has low requirements on the shape of the beverage bottle and can clamp the mouth of an irregularly round beverage bottle, and has the advantages of Wide range of applications.

Description

technical field [0001] The invention belongs to the technical field of liquid filling equipment, and in particular relates to a transmission and clamping mechanism for PET bottles. Background technique [0002] Most of the existing beverage filling machines clamp the beverage bottles through the clamping ends of the two clamping arms. A shift fork is arranged between the two clamping arms. Through the rotation of the shift fork, the two clamps are pushed respectively. The driving end of the holding arm rotates outwards and spreads out, so that the clamping ends of the two clamping arms clamp the mouth of the beverage bottle. [0003] The disadvantage of the bottle clamp of this structure is: the degree of tightness of the two clamping arms clamping the bottle mouth is determined by the distance between the driving ends of the two clamping arms by the shift fork. Since the shift fork is made of rigid material, it has no There is room for adjustment, and the shift fork is pro...

Problems solved by technology

[0003] The disadvantage of the bottle clamp of this structure is: the degree of tightness of the two clamping arms clamping the bottle mouth is determined by the distance between the driving ends of the two clamping arms by the shift fork. Since the shift fork is made of rigid material, it has no There is room for adjustment, and the fork is prone to wear when it is in contact with the two clamping arms and the transition dial. When the wear is severe, it will not be able to clamp the mouth of the beverage bottle

In addition, the bottle clamp of this structure has strict requirements on the shape of the beverage bottle and must be a standard round bottle - when the mouth of the beverage bottle is irregularly round, the two clamping arms will not be able to clamp the beverage bottle tightly mouth
