Therefore, through the elastic potential energy of the spring, the effect of adaptive tension adjustment in the process of wire material transportation is achieved, which effectively improves the effect, efficiency and stability of wire drawing.

Description

Technical Field

[0001] The utility model relates to the technical field of a drawing frame, and in particular to a drawing frame with an anti-fracture structure. Background Art

[0002] The function of the drawing frame is to improve the internal structure of the sliver, thereby improving the uniformity of its long segments, while reducing the weight unevenness, making the fibers in the sliver straight and parallel, reducing hooks, making the fineness meet the requirements, and making the raw materials of different types or qualities mix evenly to achieve the specified mixing ratio. The drawing frame is divided into two categories according to the form of the drafting mechanism: roller drafting drawing frame and gill drawing frame.

[0003] The known authorized patent with application number: CN202322061949.X discloses a drawing frame with an anti-fracture structure, including a base, a drawing frame is fixed on the top of the base, a cleaning component is arranged on the top of the base, and the cleaning component comprises: a fixed frame, the fixed frame is fixed on the top of the base, and a dust hood is slidably connected to the inner wall of the fixed frame. The drawing frame with an anti-fracture structure is provided with a cleaning component. When the drawing frame is in use, the pull plate is pulled outward, thereby driving the pull rod and the L-shaped plate to move outward, and the L-shaped plate no longer conflicts with the limit plate. At this time, under the action of spring 1 and the damper, the dust hood slowly falls down. When the bottom of the dust hood conflicts with the surface of the drawing frame, the suction fan is turned on at this time, so that the debris and dust generated by the drawing frame when in use can enter the collection box through the suction fan and the duct, so as to prevent the debris and dust from flying and causing discomfort to personnel.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when it is used, it is not convenient to automatically adjust the tension of the wire material during feeding. The above solution directly conveys the wire material into the drawing machine through the rotating drum for processing. However, during the wire material transportation, the tension of the wire material will change, and the wire material will become loose, which may easily cause the wire material to become messy or tangled, affecting the subsequent drawing effect. If the tension is too tight, it may easily cause the wire material to break, affecting the continuity and stability of the drawing, thereby reducing the effect, efficiency and stability of the drawing process.
