Cap-screwing chuck

Abstract

The invention provides a cap-screwing chuck, comprising a spindle, an adjusting assembly and a claw assembly, wherein the adjusting assembly and the claw assembly are arranged on the spindle. Particularly, the claw assembly comprises a sleeve and two clamp rods; the sleeves sleeve the spindle and in rotational connection with the spindle, the two clamp rods are symmetrically arranged on two sidesof the sleeve, bodies of the two clamp rods are hinged to the side wall of the sleeve, the two clamp rods are parallel to the axis of the hinged point of the sleeve, two springs are arranged between the bodies of the two clamp rods and the sleeve symmetrically, and the springs are arranged below the hinged point between the clamp rods and the sleeve. The adjusting assembly comprises a frustum sleeving the spindle, the conical surface of the frustum faces downwards, and an adjusting mechanism for controlling the conical surface of the frustum to be close to or far away from the upper ends of the clamp rods is arranged on the frustum. Since the distance between the lower ends of the two clamp rods is adjusted in advance through the frustum and the adjusting mechanism, the cap-crewing chuck can be matched with screw caps in different size; with the arrangement of a centering block, threads at the screw caps and bottle mouths can be protected against being damaged during screwing of the screw caps, precise adjustment and reliable clamping are achieved, and work efficiency in cap screwing is guaranteed.

Description

technical field [0001] The invention relates to the technical field of clamping jaws, in particular to a cap screwing claw head. Background technique [0002] With the continuous development of society and the continuous progress of science and technology, mechanized and automated production has gradually become a development trend. In the past, China's manufacturing boom relied on a lot of cheap labor. However, with the passage of time, with the decrease in the number of new laborers in recent years and the improvement of people's living standards, labor is no longer a cheap resource, and it has become more and more common to find a job that is difficult to find. In order to meet the needs of production, automated production has gradually valued by the company. The development and realization of mechanical automation has led mechanical production to a new field. Through the automatic control system, it has truly achieved large-scale industrial production and reduced labor...

Problems solved by technology

[0003] In the process of plastic bottle production, because the screw cap is injection-molded, it needs to be clamped after injection molding. However, the existing ones are manually clamped with pliers and tightened to install on the bottle mouth. The work efficiency is low and labor-intensive. It is laborious and not conducive to automated production. Therefore, how to design a way to quickly pick up and install the screw cap is a problem considered by researchers.
