Description

TECHNICAL FIELD

[0001] The utility model relates to fine spinning machine spinning technical field, concretely relates to a fiber limiting device for siro spinning. BACKGROUND

[0002] Siro spinning is an improved ring spinning process, which is characterized by adding a compact siro component between the drafting zone and the twisting zone of a traditional ring spinning frame. This component allows fibers to arrange in a more compact space before being twisted into yarn, thereby reducing the hairiness on the yarn surface, improving the strength and evenness of the yarn, as well as the hand feel and appearance quality of the fabric. Siro spinning technology has therefore become a key method for producing high-quality yarns and is widely applicable to cotton, polyester, wool and other fibers.

[0003] However, when dealing with pure polyester fibers, siro spinning faces a series of challenges. Due to the high strength and low elasticity of polyester fibers, it requires more force to stretch during the drafting process, and it is difficult to control as easily as softer natural fibers. In actual operation, this high drafting force makes it difficult for the siro spinning drafting zone to remain stable, especially in the twisting triangle area - the critical area between the transition of fibers from the drafting zone to the twisting point. For pure polyester, this area is not only unstable, but also requires more deformation space because the fibers are hard to bend, resulting in a larger twisting triangle area. Such conditions exacerbate the risk of fiber loss, affecting the quality of the finished yarn, such as insufficient strength, unevenness, etc. In addition, fiber loss also increases the possibility of spinning end breaks, thereby reducing production efficiency. In order to ensure product quality, the spinning speed has to be limited, which in turn restricts the improvement of production efficiency.

[0004] Therefore, the present application proposes a fiber limiting device for siro spinning to solve the above technical problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As shown in Figures 1-6 The present application provides a fiber limiting device for siro spinning, comprising:

[0027] The mounting bracket 1 is fixedly arranged on the cradle 2 and located between the front area skin roller 3 and the upper pin 4; the two guide assemblies 5 are fixedly arranged on the mounting bracket 1 and parallel to the axial direction of the front area roller 6; the plug-in base 7 is slidably arranged on the two guide assemblies 5; and the limiting sheet 8 is detachably plugged into the plug-in base 7 and abuts against the front area roller 6 at the bottom end, and the bottom end of the limiting sheet 8 is provided with a limiting hole 9 for clamping two fibers at the same time.

[0028] In use, the limiting sheet 8 is plugged into the plug-in base 7 and abuts against the front area roller 6 at the bottom end, and the two fibers at the front area roller 6 are clamped into the limiting hole 9 at the same time, thereby playing a limiting role in gathering the two fibers, so that the two fibers are gathered in advance, and the front area roller 6 and the front area skin roller 3 can better twist the two fibers, thereby reducing the twisting triangle area and improving the yarn quality. In addition, the limiting sheet 8 together with the plug-in base 7 can freely slide on the guide assembly 5, and when the positions of the two fibers are unstable and swing to a certain extent, the limiting sheet 8 can swing together with the fibers, thereby greatly reducing the shearing force applied by the limiting sheet 8 to the fibers, reducing the fiber loss, and also avoiding the limiting sheet 8 from cutting the fibers.

[0029] In an embodiment, the bottom of the mounting bracket 1 is provided with an elongated slot 10, and the guide assembly 5 includes a support 51 fixedly arranged on both sides of the slot 10 of the mounting bracket 1 and a guide rod 52 fixedly arranged on the support 51. The plug-in base 7 includes a U-shaped plug-in block 71 and four sliding sleeves 72 symmetrically arranged on both sides of the U-shaped plug-in block 71, and the sliding sleeves 72 are sleeved on the guide rod 52.

[0030] In this way, when the limiting sheet 8 is installed, the limiting sheet 8 is first moved transversely and then inserted into the slot 10 and the U-shaped plug-in block 71, and then the limiting sheet 8 is inserted downward to be combined with the U-shaped plug-in block 71, that is, the installation of the limiting sheet 8 is completed, and the disassembly is easy. When the limiting sheet 8 in the limiting hole 9 swings, a certain horizontal external force is applied to the limiting sheet 8, which drives the limiting sheet 8 together with the U-shaped plug-in block 71 and the sliding sleeve 72 to slide along the guide rod 52, thereby reducing the shearing force applied by the limiting sheet 8 to the fibers.

[0031] In an embodiment, an oil-free bushing 11 is press-fitted in the sliding sleeve 72, and the oil-free bushing 11 is sleeved on the guide rod 52.

[0032] In this way, since the sliding friction coefficient between the oil-free bushing 11 and the guide rod 52 is small, the resistance of the sliding sleeve 72 to sliding on the guide rod 52 can be reduced, and the shearing force applied by the limiting sheet 8 to the swinging fibers is further reduced.

[0033] In an embodiment, two springs 12 are sleeved on each guide rod 52, and the two springs 12 are located at two ends of the guide rod 52 respectively, one end of the spring 12 abuts against the end of the support 51, and the other end abuts against the sliding sleeve 72.

[0034] In this way, when the limiting piece 8 and the plug-in base 7 are driven by the swinging fiber to slide along the guide rod 52, the plug-in base 7 extrudes the spring 12 and makes it contract, the spring 12 exerts a certain resistance on the plug-in base 7 and drives it to reset, and then the limiting piece 8 on the plug-in base 7 drives the swinging fiber to reset, thereby reducing the amplitude of the fiber swing, improving the stability of the twisting triangle area, and improving the yarn quality.

[0035] In an embodiment, the top of the limiting piece 8 is fixedly provided with a reverse L-shaped buckle 13 on both sides, which is used for buckling the side wall of the U-shaped plug-in block 71, and after the limiting piece 8 is inserted into the U-shaped plug-in block 71, the two ends of the buckle 13 abut against the sliding sleeve 72.

[0036] In this way, the buckle 13 is inserted with the side wall of the U-shaped plug-in block 71, and the two ends of the buckle 13 abut against the sliding sleeve 72, that is, the positioning and installation of the limiting piece 8 are completed, which is convenient and fast and convenient to disassemble.

[0037] In an embodiment, the part of the limiting piece 8 at the bottom where the limiting hole 9 is provided is thickened.

[0038] In this way, the stability of the limiting piece 8 abutting against the front zone roller 6 is improved, and the depth of the limiting hole 9 is increased, thereby ensuring the limiting effect of the fiber.

[0039] In an embodiment, a lifting hole 14 is provided at the top of the limiting piece 8.

[0040] In this way, the operator can more conveniently insert and pull out the limiting piece 8 through the lifting hole 14.

[0041] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.

[0042] It should be noted that if the present application involves directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0043] In addition, "multiple" refers to two or more. In addition, the technical solutions among various embodiments can be combined with each other, but must be based on the fact that a person of ordinary skill in the art can realize it, and when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of such technical solutions does not exist, nor is it within the protection scope required by the utility model.
