Doubling machine capable of preventing yarn from dissociating

Abstract

The utility model relates to the technical field of doubling machines, in particular to a doubling machine capable of preventing yarn dissociation. The technical problems to be solved are that yarn loosening caused by excessive pay-off of a bobbin due to excessive rotation of the bobbin during pay-off is inconvenient to prevent, the yarn is easy to droop in the yarn conveying process, an existing doubling machine is difficult to limit the yarn while keeping the tension of the yarn, the yarn is easy to swing when being pulled, and the yarn conveying efficiency is low. And therefore, the yarn dissociation is avoided. A doubling machine capable of preventing yarn from dissociating comprises a base used for being fixed to a table top, a motor fixedly connected to one side of the base, a wind-up roller clamped to an output shaft of the motor and two rotating rods rotationally connected to one side of the base. The bobbin rotates to drive the ratchet wheel through the rotating rod, and the rotating block always abuts against the ratchet wheel, so that excessive yarn outlet and bobbin reverse rotation caused by unstable doubling tension are prevented, loosening caused by excessive yarn release of the bobbin is prevented, and yarn dissociation is prevented.

Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of doubling machine technical field, especially a kind of doubling machine to prevent yarn to be free. BACKGROUND

[0002] When doubling yarn, in order to ensure the quality of yarn after doubling, it is necessary to prevent yarn from being free during doubling. The doubling machine usually uses the method of adjusting yarn tension to reduce yarn free during doubling.

[0003] However, the current doubling machine is not convenient to prevent the spool from rotating excessively during yarn feeding, which causes the yarn to be loose and the yarn to sag during yarn conveying. The existing doubling machine cannot maintain the tension of the yarn while limiting the yarn, which causes the yarn to swing easily when pulled, resulting in yarn free. UTILITY MODEL CONTENTS

[0004] To overcome the above shortcomings, the utility model provides a kind of doubling machine to prevent yarn to be free, which can prevent the spool from rotating excessively during yarn feeding, making the yarn not easy to loosen, and can maintain the tension of the yarn while limiting the yarn, making the yarn not easy to swing when pulled, thereby preventing the yarn from being free.

[0005] The technical solution is: a kind of doubling machine to prevent yarn to be free, comprising:

[0006] a base for fixing on the table top;

[0007] a motor fixed to one side of the base;

[0008] a winding roller connected to the output shaft of the motor;

[0009] two rotating rods rotatably connected to one side of the base;

[0010] spools respectively connected to the two rotating rods;

[0011] a doubling assembly provided on the base;

[0012] a limiting assembly provided on the base;

[0013] an anti-loose assembly provided on the rotating rod and the base;

[0014] Further, the doubling assembly includes two limiting cylinders fixed to the base, a fixed cylinder fixed between the two limiting cylinders, a plurality of sliding frames slidingly connected to the fixed cylinder, a tension spring connected between the sliding frame and the fixed cylinder, and a rotating wheel rotatably connected to the sliding frame.

[0015] Further, one side of the limiting cylinder is an expanded port structure.

[0016] Further, the limiting assembly comprises a fixing frame fixed to the base, a sliding groove is formed in the fixing frame, two sliding blocks are slidably connected to the sliding groove of the fixing frame, and a limiting wheel is rotatably connected to each of the two sliding blocks; two compression springs are connected between each of the two sliding blocks and the fixing frame; and a limiting shell is fixed to one side of the fixing frame.

[0017] Further, the anti-loosening assembly comprises a ratchet wheel fixed to one end of each of the two rotating rods, two rotating blocks rotatably connected to the base, and a torsion spring connected between each of the two rotating blocks and the base.

[0018] The motor's output shaft drives the take-up roller to rotate, the take-up roller drives the yarn to move, the yarn drives the spike wheel to rotate, and the spike wheel combines the two yarns into one yarn under the action of the stretching spring, thereby improving the quality of the combined yarn.

[0019] 2. When the yarns are combined, the spool is driven to rotate by the rotating rod, the ratchet wheel is repeatedly pressed by the rotating block, the rotating block is always pressed against the ratchet wheel under the action of the torsion spring, thereby preventing the combined yarn from being excessively pulled out and the spool from being reversed, preventing the spool from being excessively pulled out and causing the yarn to be loose, preventing the yarn from being loose, and the take-up roller drives the yarn to move while straightening the yarn under the action of the tension, the yarn is pressed by the two limiting wheels while moving, the limiting wheels press the two yarns towards each other under the action of the compression spring, thereby ensuring that the yarn does not deviate, maintaining the tension of the yarn and limiting the yarn, thereby preventing the yarn from swinging when being pulled, and further improving the quality of the subsequent combined yarn.
