An automatic tightening device for bottle caps with external threads

Abstract

The invention relates to an automatic tightening device for externally threaded bottle caps, which belongs to the technical field of packaging machinery and solves the problem that existing tightening devices cannot meet the requirements of metal externally threaded bottle caps with large quality, poor elasticity and plasticity, small pitch, and many turns. The problem that the thread in the bottle is tightened and the degree of automation is low. The automatic tightening device includes a frame and a conveying device for delivering product bottles and caps to designated positions; the frame is provided with a bottle alignment clamping assembly and a bottle cap tightening assembly; the bottle alignment clamping assembly Clamping cylinder and horizontal cylinder, wherein, the centering clamping cylinder is used to clamp the product bottle body; the horizontal cylinder positions the centering clamping cylinder to the working position by controlling the horizontal movement of the centering clamping cylinder; bottle cap tightening assembly It includes a tightening head, a servo unit for driving the rotation of the tightening head, and a vertical cylinder for controlling the servo unit to move up and down. The invention realizes the automatic tightening of the bottle cap with external thread.

Description

technical field [0001] The invention relates to the technical field of packaging machinery, in particular to an automatic tightening device for bottle caps with external threads. Background technique [0002] At present, there are mature bottle cap tightening equipment, which can realize automatic tightening between plastic bottle caps and plastic bottle bodies, between metal bottle caps and glass bottle bodies, and its product features are: [0003] 1) The quality of the bottle cap is small, and the material is mostly plastic or metal material with good elasticity and plasticity; [0004] 2) The thread of the bottle cap is mainly internal thread, and the thread of the bottle body is mainly external thread; [0005] 3) The pitch of the thread is generally 2 to 3 mm, and the number of turns is generally 2 to 3 turns; [0006] The tightening torque required in such cases is usually small, and the tightening principle is mainly through the contact between the tightening head ...
