Bobbin pressing device

Abstract

A bobbin pressing device comprises a cylinder, a pressing piece and a control module. The control module is arranged on doffing equipment, the pressing piece comprises a first pressure plate, a second pressure plate and a connecting plate between the two pressure plates, the second pressure plate is positioned on the right side of the connecting plate and is higher than the first pressing plate, the first pressure plate is fixed onto a piston rod of the cylinder, and the cylinder is connected onto the control module. When the doffing equipment moves rightwards at a speed of V, the control module can control the cylinder to move leftwards relative to the doffing equipment at a speed of V along an arrangement direction of empty bobbins, and also can control the cylinder to move rightwards relative to the doffing equipment at a speed of 2XV along the arrangement direction of the empty bobbins, and the movement direction of the piston rod of the cylinder is perpendicular to the arrangement direction of the empty bobbins. According to the scheme, the bobbin pressing device has the advantages that the pressing piece can be assuredly static relative to the empty bobbins in the left-right direction in a downward pressing procedure, and spindle blades are prevented from being damaged in the downward pressing procedure.

Description

technical field [0001] The invention relates to a textile machine, in particular to a yarn pressing tube device of a ring spinning machine. Background technique [0002] After the empty bobbin on the ring spinning machine is inserted into the spindle bar, it needs to be pressed in place to ensure a consistent height, so as to facilitate the subsequent work of winding the yarn. In actual work, manual methods are often used to photograph empty bobbins one by one, which is not only low in production efficiency but also high in labor intensity; in order to improve this situation, people have developed a tube crimping machine. It is easy to generate lateral force in the middle and cause damage to the spindle bar. Contents of the invention [0003] The object of the present invention is to provide a yarn pressing tube device which does not damage the spindle bar during the tube pressing process and has a simple structure. [0004] In order to achieve the above object, the tech...
