Description

Technical Field

[0001] This utility model belongs to the technical field of guiding devices, and specifically relates to a guiding device for polyester master yarn. Background Technology

[0002] Polyester masterfilament is a type of polyester filament with a specific structure. It can be understood as the "mother" of a "filament family". Polyester masterfilament is a polyester filament with a multifilament structure, which can be separated into several finer monofilaments. As an intermediate raw material for the production of monofilaments, monofilament separation is its key purpose. The monofilaments obtained after separation can be used in textiles, clothing and other fields. The core value of polyester masterfilament lies in its role as an intermediate raw material. Its ultimate goal is to obtain high-performance monofilaments through the separation process. The production process of polyester masterfilament is similar to that of conventional FDY (fully drawn yarn), mainly involving the steps of "slicing → spinning → cooling → oiling → stretching and setting → winding". When winding polyester masterfilament, winding equipment is required. Among them, the reciprocating yarn guide device is a crucial structure in the polyester masterfilament winding equipment.

[0003] When a reciprocating yarn guide device is used for winding polyester master yarn, it evenly arranges the polyester master yarn on the drum. Its general structure consists of a lateral reciprocating mechanism in conjunction with a guide roller to guide the yarn to move back and forth to achieve uniform winding. Traditional lateral reciprocating mechanisms require a reciprocating screw, which is usually exposed externally. Even if there is an external housing for protection, a through groove needs to be opened on the housing for the linkage fast travel of the reciprocating screw. After long-term use, external dust and lint from the polyester master yarn can easily fall onto the surface of the reciprocating screw through this through groove. The increase of foreign matter on the surface of the reciprocating screw can easily increase the frictional resistance between the reciprocating screw and the linkage nut, which can easily lead to jamming and disrupt the smoothness of the reciprocating motion. Utility Model Content

[0004] The purpose of this invention is to provide a guide device for polyester filaments, which has the advantage of ensuring smooth reciprocating motion.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyester master yarn guiding device, comprising a frame, a connecting block disposed inside the frame, an mounting block fixedly connected to the top of the connecting block, a fixing frame disposed on the top of the mounting block, a guide wheel symmetrically rotatably connected inside the fixing frame, a follow-up dustproof belt that is interlocked with the connecting block disposed on the top of the frame, guide rollers symmetrically disposed on the top of the frame and drivenly connected to the follow-up dustproof belt, both ends of the guide rollers being rotatably connected to fixing seats bolted to the frame via rotating shafts, and a through passage for use with the follow-up dustproof belt being opened on the mounting block.

[0006] The above technical solution is adopted: This utility model has a follow-up dustproof belt on the top of the frame, and the follow-up dustproof belt is fixedly sleeved with the connecting block. With the use of two guide rollers, when the connecting block drives the mounting block to move back and forth on the frame, the follow-up dustproof belt is located between the two guide rollers and rotates back and forth with the movement of the connecting block, sealing the opening of the frame. Foreign objects from the outside cannot enter the interior of the frame, ensuring the smooth operation of the reciprocating screw.

[0007] The present invention is further configured such that a reciprocating lead screw is rotatably connected inside the frame, the reciprocating lead screw is threadedly connected to the center of the connecting block, and one end of the reciprocating lead screw extends through to the outside of the frame and is bolted with a stepper motor.

[0008] The above technical solution is adopted: when the stepper motor is started, it can drive the reciprocating lead screw to rotate, and the rotation of the reciprocating lead screw can drive the connecting block to move.

[0009] The present invention is further configured such that locking blocks are symmetrically bolted to the surface of the stepper motor, and the locking blocks are fixedly connected to one end of the frame.

[0010] The above technical solution can be used to fix and limit the movement of a stepper motor.

[0011] The present invention is further configured such that sliding blocks are symmetrically mounted on the surface of the connecting block, and a sliding groove is provided inside the frame to slide and connect with the sliding blocks.

[0012] The above technical solution is adopted to slide and limit the movement of the connecting block inside the frame.

[0013] The present invention is further configured such that a storage groove is provided on the top of the frame, and the storage groove is connected to the inner cavity of the frame.

[0014] The above technical solution facilitates the placement of the moving dustproof strip, which is located inside the storage slot and can seal the opening of the entire frame.

[0015] The present invention is further configured such that a support sleeve is fixedly connected to the top of the mounting block, a support rod is provided inside the support sleeve and bolted to the fixing frame, and a limit bolt is threadedly connected to the surface of the support sleeve, one end of the limit bolt passing through the interior of the support sleeve and abutting against the support rod.

[0016] The above technical solution provides support for the fixed frame, and the support rod can be adjusted in height inside the support sleeve. The limiting bolt limits the position of the support rod inside the support sleeve, thereby achieving the purpose of adjusting the support height of the fixed frame.

[0017] The present invention is further configured such that guide blocks are symmetrically mounted on the surface of the support sleeve rod, and a guide groove is provided inside the support sleeve to slide and connect with the guide blocks.

[0018] The above technical solution involves sliding and limiting the movement of the support sleeve rod within the support sleeve.

[0019] In summary, this utility model has the following beneficial effects: This invention features a follow-up dustproof belt at the top of the frame, which is fixedly connected to the connecting block. In conjunction with two guide rollers, when the connecting block drives the mounting block to reciprocate on the frame, the follow-up dustproof belt rotates between the two guide rollers as the connecting block moves, sealing the opening of the frame and preventing foreign objects from entering the interior of the frame, thus ensuring smooth operation of the reciprocating screw.
