Problems solved by technology

In the current main drafting device, the design of the fast-rotating rear drafting roller group is unreasonable, so that the top cannot be clamped and moved forward by the rear drafting roller group, which eventually leads to poor drafting effect of the wool top; Moreover, the two drafting roller groups are driven to rotate by a number of friction wheels and transmission belts respectively. When the transmission belt and the friction wheels cooperate, the transmission belt is easy to slip, so that the rotation speed of the two drafting roller groups cannot be kept constant, which will also cause the sliver of the top. Poor drafting effect

Embodiment Construction

[0014] The present invention will be further described in detail below in conjunction with specific embodiments and accompanying drawings. In order to clearly reflect the relevant structure of the main drafting device in the top cutting machine, only part of the frame is drawn in the accompanying drawings.

[0015] Main drafting unit in top cutting machines, e.g. figure 1 As shown, the frame 10 is included, and the front draft roller group is installed on the front portion of the frame 10. The front draft roller group includes a front pinch roller 32 and a front traction roller 31, and the front pinch roller 32 is located at the front traction roller 31. The top of the front pressure roller 32 is installed on the front elastic support 3 by bearings, the front elastic support 3 is hinged with the frame 10, and the front traction roller 31 is installed on the frame 10 by bearings, and the front elastic support 3 is also mounted on the top of the front elastic support 3. A front...

Abstract

The invention discloses a main drafting device of a wool top cut-off machine. The main drafting device of the wool top cut-off machine comprises a machine frame. A front drafting roll set is installed at the front portion of the machine frame and comprises a front compression roll and a front pull roll. A rear drafting roll set is installed at the rear portion of the machine frame and comprises a rear compression roll, a first rear pull roll and a second rear pull roll, wherein the first rear pull roll and the second rear pull roll are arranged in parallel; the rear compression roll is located above the first rear pull roll and the second rear pull roll, and the rear compression roller, the first rear pull roll and the second rear pull roll are distributed in the shape like a character 'pin'. The machine frame is provided with a rear drive device and a front drive device. The rear drive device can drive the first rear pull roll and the second rear pull roll to rotate in the same direction. The front drive device can drive the front pull roll, the first rear pull roll and the second rear pull roll to rotate in the same direction. Wool tops are pulled by the front pull roll, the first rear pull roll and the second rear pull roll to move from the front drafting roll set to the rear drafting roll set. The main drafting device of the wool top cut-off machine is reliable in operation, low in noise and good in wool top drafting effect.

Description

technical field [0001] The invention relates to a main drafting device for top drafting in a top cutting machine. Background technique [0002] The main drafting device in the conventional wool top cutting machine is equipped with two drafting roller groups, and the speeds at which the two drafting roller groups drive the wool top to move forward are different. Groups are stretched. In the current main drafting device, the design of the fast-rotating rear drafting roller group is unreasonable, so that the top cannot be clamped and moved forward by the rear drafting roller group, which eventually leads to poor drafting effect of the wool top; Moreover, the two drafting roller groups are driven to rotate by a number of friction wheels and transmission belts respectively. When the transmission belt and the friction wheels cooperate, the transmission belt is easy to slip, so that the rotation speed of the two drafting roller groups cannot be kept constant, which will also cause...
