Description

An upper pin with a roller structure

technical field

The utility model relates to the technical field of spinning, in particular to an upper pin with a roller structure.

Background technique

The upper pin is the key part in the drafting of the spun yarn, and the jaw composed of the upper pin, the lower pin and the roller is the key area in the drafting of the spun yarn, in which the rear jaw is the drafting jaw, and the front jaw is the holding jaw. Therefore, any slight change in the structure of the upper pin will have a major impact on the drafting of the sliver. The jaw formed by the upper pin and the roller also directly affects the holding force and friction force in the drafting process, and also determines the drafting force. The floating area in the stretching process has a significant impact on the evenness, hairiness and strength of the yarn. Traditionally, the pin does not have a pressure rod. If you need to add a pressure rod, you must install a spacer pressure rod, which is fixed on the upper pin through a distance block. On the pin, it is integrated with the upper pin, and then better controls the floating fiber from the upper and lower apron jaws to the front roller, and improves the yarn quality.

The upper pins with front pressure rods currently used all adopt a single pressure rod structure, which makes the control of the floating fibers of the front roller insufficient during spinning, so that the fibers after drafting are lost more before twisting, and the ends are more likely to be broken. Many phenomena affect spinning efficiency and yarn quality. In view of this, this patent provides an upper pin with a roller structure. By installing rollers in front of the left and right pins of the upper pin, the apron is tensioned on the rubber roller and the roller, so that the distance between the apron and the upper pin The original sliding friction is converted into rolling friction, thereby reducing the wear on the apron during operation, improving the control of the fiber by the apron jaw structure, and improving spinning efficiency and yarn quality.

Contents of the invention

The purpose of this utility model is to provide an upper pin with a roller structure. By installing rollers in front of the left and right pins of the upper pin, the apron is tensioned on the rubber roller and the roller, so that the gap between the apron and the upper pin The original sliding friction is converted into rolling friction, thereby reducing the wear on the apron during operation.

In order to achieve the above purpose, the technical solution adopted by the utility model is: an upper pin with a roller structure, including a connecting end and a pin body, and the connecting end includes a rubber roller connecting end and a pin body connecting end, and the rubber roller The connecting end and the connecting end of the pin body are integrally connected. The connecting end of the rubber roller is an arc-shaped structure. The rubber roller is fixed on the upper pin by being embedded in the connecting end of the rubber roller. The pin body includes a left pin piece and a right pin piece , the left pin and the right pin are connected to the left and right ends of the connecting end of the pin body through the left spring and the right spring, the left pin and the right pin are hollow structures, including the bottom and the left side, the bottom and the left side The surfaces are connected by an arc surface, the left side is connected to the connecting end of the pin body through a spring, and a first left connecting end is installed on the left edge and the right edge of the connecting end of the arc surface and the bottom surface of the left pin and the first right connection end, the first left connection end and the first right connection end are connected with a left roller through the first left bearing and the first right bearing, and on the left side of the arc surface of the right pin and the bottom surface connection end The edge and the right edge are equipped with a second left connection end and a second right connection end, and the second left connection end and the second right connection end are connected with a right roller through a second left bearing and a second right bearing, and the apron stretches Tightly on the rubber roller and the left roller or the right roller and connected with the upper pin.

When in use, the apron is stretched on the rubber roller and the left or right roller and connected with the upper pin, so that the original sliding friction between the apron and the upper pin is converted into rolling friction, thereby reducing the impact on the apron during operation. Wear, improve the control of the apron jaw structure on the fiber, improve spinning efficiency and yarn quality.
