Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a feeding device for a roving frame guide frame. Background Art

[0002] Modern textile refers to a multi-scale structural processing technology for fibers or fiber aggregates. The sliver guide is a device that is often used in the field of textile technology. It plays a guiding role for textile slivers. The height and angle of existing sliver guides cannot be adjusted, which often leads to accidental breakage of the slivers and affects production quality.

[0003] In order to solve the above problems, a Chinese utility model patent with authorization announcement number CN206986399U discloses a guide frame for a roving machine, including a base, hydraulic cylinders are installed on the left and right sides of the top of the base, hinged seats are installed on the top power output ends of the two groups of hydraulic cylinders, roller frames are installed on the top of the two groups of hinged seats, the top and bottom of the roller frames are evenly slidably connected with bearing boxes, the inner cavity of the bearing box is fixed with bearings, the bottom of the inner cavity of the top bearing and the top of the inner cavity of the bottom bearing are fixedly plugged with rotating shafts, the top rotating shaft and the bottom rotating shaft respectively pass through the top and bottom of the roller frame, a roller is installed between the top rotating shaft and the bottom rotating shaft, and they are connected by an electric telescopic rod.

[0004] The principle is: by setting two hydraulic cylinders on the upper end of the base, and then connecting the output end of the hydraulic cylinder to the bottom of the roller frame through a hinge seat, the hydraulic cylinder drives the roller frame to adjust the height and angle, and the electric telescopic rod is set to adjust the spacing of the rollers in the roller frame. However, the prior art has the following problems: Figure 1 In order to improve the inclination adjustment effect, the output end of the hydraulic cylinder and the roller frame are movably connected through a hinge seat. The use of a hinge seat for movable connection means that there is a movable gap between the roller frame and the hydraulic cylinder, and there is a lack of a locking structure. In the process of guiding the strips, the roller frame is prone to shaking under the action of external force, causing the strip guide to deviate from the preset direction, affecting the processing quality.
