Cap head pressing device

Abstract

The invention discloses a cap head pressing device for sealing and pressing a bottle cap in beverage machinery. The cap head pressing device comprises a lifting shaft which is movably arranged in a guide seat, wherein a roller is arranged at the upper end of the lifting shaft; a connection block and a cap pressing seat are fixedly connected with the lower end of the lifting shaft; a spring sleeve and a balance spring are arranged inside the cap pressing seat; a protecting bush is fixedly connected to the lower end of the cap pressing seat; a cap pressing body is arranged inside the protecting bush; a plurality of small holes are arranged in the cap pressing body; a claw head capable of clamping the bottle cap is arranged in each small hole; an elastic O-shaped ring is hooped at the outer end of the claw head; a cap opening rod movably penetrates through the connection block and the cap pressing body; the inner end of a cap opening pin shaft is connected with the upper end of the cap opening rod; the outer end of the cap opening pin shaft stretches out a cap opening elongated slot on the side wall of the lifting shaft and then a cap opening roller is arranged, and a clamping spring is sheathed on the cap opening rod. The cap head pressing device disclosed by the invention can be applicable to bottle caps in multiple specifications and the stability of cap pressing is greatly improved.

Description

technical field [0001] The invention relates to the field of beverage mechanical equipment, in particular to a capping head device for sealing bottle caps. Background technique [0002] In the beverage production line, the beverage bottles filled with beverages need to be capped, and this work is mainly completed by the capping head device. see figure 1 As shown, the structure of the currently used capping head device includes: a lift shaft 4 that is movably arranged in the guide seat 3, the lift shaft 4 and the guide seat 3 are circumferentially locked and can slide mutually in the axial direction, and rollers are installed on the upper end of the lift shaft 4 1. A gland seat 24 is connected to the lower end of the lifting shaft 4, and a spring sleeve 12 is installed in the gland seat 24, and a spring 22 is installed in the inner cavity of the spring sleeve 12; a sheath 18 is connected to the lower end of the gland seat 24, and A gland body 19 is installed in the sleeve 1...

AI Technical Summary

Problems solved by technology

[0004] The disadvantages of the capping head device with the above structure are: 1. It can only be applied to conventional bottle caps. Once the bottle cap is too large, too heavy, or the top surface of the bottle cap is uneven and causes air leakage, the bottle cap will be adsorbed. Accidents caused by falling due to unstoppability, thus affecting the quality and speed of the gland; 2. Since the vacuum generator must be used in the work, the cost of compressed air is increased, which is not conducive to energy saving and consumption reduction
