Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings.

[0028] A constant torque capping head assembly, including a capping head 1, a buffer mechanism 2, a magnetic sleeve 3, a rotating assembly 4 and a capping head assembly 5 for holding a bottle cap. The upper end of the capping head 1 is provided with a The internal thread connected to the capping machine, the magnetic sleeve 3 is connected to the capping head 1 through the buffer mechanism 2 and the magnetic sleeve 3 can rotate synchronously with the capping head 1. The rotating assembly 4 includes a magnetic rotating sleeve 42 and a magnetic rotating sleeve 42. Double bearings 41, the magnetic rotating sleeve 42 is installed in the magnetic sleeve 3 through the double bearing 41, the inner magnetic ring 31 is nested in the inner side of the magnetic sleeve 3, and the magnetic rotating sleeve 42 is provided with an outer ring with the same height as the inner magnetic ri...

Abstract

The invention relates to a capping head assembly with a constant torsion. The capping head assembly comprises a close cover, a buffer mechanism, a magnetic sleeve, a rotating assembly and a cap grasping assembly, wherein the magnetic sleeve is connected with the close cover through the buffer mechanism and can rotate synchronously with the close cover, the rotating assembly comprises a magnetic rotating sleeve, an inner magnetic ring is nested inside the magnetic sleeve, the magnetic rotating sleeve is provided with an outer magnetic ring, both the inner and outer magnetic rings are provided with a plurality of magnets, these magnets are uniformly arranged into a circle, magnetic poles of two adjacent magnets at the same side are opposite, and the number of magnets in the outer and inner magnetic rings is the same. The close cover and the magnetic sleeve rotate along with a motor, thus to drive the rotating assembly and the cap grasping assembly to rotate synchronously, achieving a sealing effect. When the close cover gets to position or receives a set torque, the close cover and the magnetic sleeve continue rotating whereas the rotating assembly stops rotating with the magnetic sleeve, thereby avoiding over-twisting. When magnetic poles are switched, pulses can be removed to the largest extent, a constant torsion is guaranteed, the cap is protected from over-twisting when being closed.

Description

technical field [0001] The invention belongs to the technical field of packaging equipment, and in particular relates to a constant torque capping head assembly. Background technique [0002] Screw cap sealing technology is widely used in beverages (including carbonated beverages, packaged water, mineral water), dairy products (including milk, milk beverages), fruit juices (including concentrated juice, jam and fruit drinks), condiments (soy sauce, Vinegar) and edible oil and other liquid (liquid) food filling industries are also widely involved in pharmaceutical, cosmetic, lubricant, chemical and other industries. [0003] The screw-type screw cap seal has evolved from the early purely mechanical screw seal to the magnetic force of two magnets to control the capping torque, which partially overcomes the uncontrollable defect of the pure mechanical screw seal torque (over-torque or cap not in place). However, due to the insurmountable defects of the two-piece magnet magneti...
