Description

Technical Field

[0001] This utility model relates to the field of drawing frame technology, and in particular to an adjustable drawing frame. Background Technology

[0002] The drawing frame is a key piece of equipment in the textile industry used to improve the quality of fiber slivers. It is mainly used to process multiple combed or finely combed fiber slivers into fiber slivers with higher uniformity through processes such as drawing and stretching.

[0003] A search revealed a Chinese patent with publication number CN202322128928.5, which discloses a drawing machine for merging cotton slivers. By setting up a drawing assembly, the cotton sliver is guided by rollers after entering the sliver flare. The rolling of the rollers reduces the friction on the cotton sliver, preventing wear and burrs, and also preventing blockage at the flare. A guide assembly is also included to facilitate the placement of the cotton sliver into the guide assembly after removing the guide rollers. Furthermore, the spacing between the separating rollers can be adjusted according to the thickness of the cotton sliver, preventing the spacing from being too small, which would cause the cotton sliver to be clamped too tightly, affecting its movement and increasing wear.

[0004] The above-mentioned technical solution has the following drawbacks. Although the structure of such a drawing frame allows the bolts to be loosened to adjust the spacing of the slitting rollers as needed, thereby preventing wear on the cotton sliver, manual adjustment is required in actual use, which is inconvenient. Therefore, an adjustable drawing frame is proposed, which can adjust the spacing of the drawing frame slitting rollers according to the actual spacing of the cotton sliver. The adjustment method is electric, which is more convenient and faster. Tension rollers are provided to provide tension to the fiber sliver, making the cotton sliver more stable during transport.

[0005] In view of this, this work improves and solves the above problems. Through dedicated research and application of theoretical principles, a technical solution with a reasonable design that can effectively improve the above defects has finally been proposed.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the general background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] This utility model provides an adjustable drawing frame that solves the problems mentioned in the background. The spacing between the drawing frame's dividing rollers can be adjusted according to the actual spacing of the cotton sliver, and the adjustment method is electric, which is more convenient and faster. It is equipped with a tension roller to provide tension to the fiber sliver, so that the cotton sliver can be conveyed more smoothly.

[0008] The present invention provides the following solution to the above-mentioned technical problems: An adjustable drawing frame includes a drawing frame body, an adjusting frame, a slitting roller, and a roller frame. The drawing frame body is provided with a drawing wheel and a feed hopper. The adjusting frame is connected to the drawing frame body by screws. The adjusting frame is equipped with a brake servo motor. The drive end of the brake servo motor is fixedly connected to an adjusting shaft. The slitting roller is rotatably connected to a lead screw nut. The adjusting shaft is provided with an adjusting thread corresponding to the lead screw nut. The drawing frame body is equipped with a top cover by screws. The roller frame is rotatably connected to a tension roller. There are two roller frames, which are respectively placed on both sides of the adjusting frame. Spring telescopic rods are evenly fixedly installed on the roller frames. The spring telescopic rods are fixedly connected to the drawing frame body.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the adjusting threads are provided in multiple sets corresponding to the lead screw nut, and each set of adjusting threads has two threads, which are arranged symmetrically.

[0011] Furthermore, the lead screw nut is fixedly mounted with an auxiliary pulley.

[0012] Furthermore, the top cover has a strip-shaped hole corresponding to the lead screw nut, and the lead screw nut passes through the strip-shaped hole and is rotatably connected to the slitting roller.

[0013] Furthermore, the adjusting shaft is uniformly and fixedly mounted with a limiting plate.

[0014] Furthermore, the adjusting frame is uniformly and fixedly equipped with positioning bearings, and the positioning bearings are rotatably connected to the adjusting shaft.

[0015] Furthermore, one end of the adjusting shaft is rotatably connected to the inner wall of the adjusting frame.

[0016] This utility model provides an adjustable drawing frame, which has the following advantages:

[0017] 1. The cotton sliver is transmitted through the tension roller on one side to the gap of the slitting roller, and then through the other roller frame to the feed hopper for slitting processing by the drawing wheel. There are multiple sets of slitting rollers, two in each set. The gap between the two slitting rollers is the material passage position. The diameter of the cotton sliver is measured. The brake servo motor is started to rotate the adjustment shaft. The adjustment shaft can drive the slitting roller to adjust the material passage position spacing under the limit action of the strip hole through the screw nut.

[0018] 2. The limit plate can limit the lead screw nut to prevent it from coming out at the adjustment thread. After the spacing is adjusted by measuring with a ruler, the brake servo motor stops and the brake function of the brake servo motor is activated, so as to ensure that the slitting roller is positioned in the adjustment position.

[0019] 3. The spring telescopic rod can support the tension roller of the roller frame, so that the cotton sliver can be smoothly conveyed for drawing processing;

[0020] 4. This adjustable drawing frame allows for adjustment of the spacing between the drawing rollers according to the actual spacing of the sliver, making it suitable for drawing slivers of different sizes. It has better applicability, and the adjustment is electric, making it more convenient and faster. It is also equipped with tension rollers to provide tension to the fiber sliver, making the sliver more stable during transport.
