Description

Technical Field

[0001] This utility model pertains to yarn manufacturing machinery components, and particularly relates to a single-spindle traverse yarn guiding device. Background Technology

[0002] In the yarn winding process of yarn manufacturing equipment such as twisting machines and spinning machines, the yarn is driven to move reciprocally laterally by the guide head of the traverse yarn guide device, thereby controlling the yarn winding angle and winding density. Patent No. ZL201810213685.6 discloses a yarn electronic forming device that uses a servo motor to drive a traverse rod to move reciprocally via a transmission mechanism. The servo motor is located at the head or tail of the machine, and the traverse rods of the entire device are connected end-to-end. One end of the traverse rod is engaged with a synchronous belt ring, which is fitted onto a synchronous pulley. Driven by the forward and reverse rotation of the servo motor, the traverse rod moves reciprocally in a linear fashion, simultaneously driving the traverse guide heads of each spindle to move traversely. However, this centralized drive traverse yarn guide device requires the entire machine to be wound into identical yarn bobbins, making precise control of individual spindles impossible. The process is limited and cannot adapt to the manufacturing of various yarn types and yarn bobbin formation. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing centralized drive yarn bobbin forming traverse yarn guiding devices in yarn manufacturing equipment, which cannot achieve precise control of a single spindle. This invention provides a single-spindle traverse yarn guiding device that is simple and compact in structure, stable in operation, and capable of achieving precise control of a single spindle.

[0004] Therefore, the present invention adopts the following technical solution: a single-spindle traverse yarn guiding device, comprising a frame, a yarn guiding head, and a motor, characterized in that a motor mounting position is provided on the frame corresponding to each spindle winding device, and a motor is installed in each motor mounting position. The single-spindle traverse yarn guiding device further includes a synchronous belt ring, a driving synchronous pulley, and a support pulley. Each support pulley is supported and installed by a support shaft mounted on the frame. A synchronous belt ring is sleeved on every two support pulleys, forming a straight section between the two support pulleys for fixing the yarn guiding head. The outer surface of the synchronous belt ring is toothed. A driving synchronous pulley is installed on the shaft of each motor, and each driving synchronous pulley meshes with the outer surface of a synchronous belt ring. By rotating the motor forward and backward, the synchronous belt ring rotates forward and backward, causing the yarn guiding head installed on the straight section of the synchronous belt ring to move linearly back and forth.

[0005] As a supplement and improvement to the above technical solution, this utility model also includes the following technical features.

[0006] The single-spindle transverse yarn guiding device also includes at least one transmission pulley, which is supported by a support shaft and mounted on the frame and located inside the synchronous belt loop, thereby increasing the wrap angle of the synchronous belt loop on the driving synchronous pulley.

[0007] The center of the active synchronous pulley is located on the vertical midline of the line connecting the centers of the two support pulleys.

[0008] The number of transmission pulleys is two, and they are symmetrically arranged with the vertical center line as the center line.

[0009] The synchronous belt ring is a single-sided toothed synchronous belt, and the support pulley and transmission pulley are both smooth wheels with a smooth cylindrical outer circumference supporting the synchronous belt ring. The structure is simple and can reduce costs.

[0010] The single-spindle transverse yarn guiding device also includes a yarn guide head guiding and limiting mechanism, which guides and limits the linear reciprocating motion of the yarn guide head.

[0011] The yarn guide head guiding and limiting mechanism includes a guide groove and a guide block embedded in the guide groove. The guide block and the guide groove form a sliding fit. A synchronous belt slot is provided in the guide block. The straight section of the synchronous belt loop located between the two support pulleys is located in the guide groove and is fixedly locked in the synchronous belt slot. The yarn guide head is fixedly connected to the guide block.

[0012] Limiting blocks are provided on both sides of the top of the guide block. The guide groove is a stepped groove with a top width greater than the bottom width. The limiting blocks are located at the top of the guide groove. Cover plates are respectively installed on both sides of the top of the guide groove to limit the guide block in the depth direction of the guide groove.

[0013] One side of the cover plate cooperates with the frame to form an accommodating space, and the active synchronous pulley is located in the accommodating space to prevent dust from getting tangled on the active synchronous pulley, thus avoiding slippage caused by affecting the meshing of the active synchronous pulley and the synchronous belt.

[0014] The yarn guide head is provided with an overhanging part, on which a yarn passage hole with an open side is formed. A yarn sliding guide surface is formed on the side of the overhanging part relative to the guide slider, so that the yarn can slide into the yarn passage hole from the open side of the yarn passage hole when threading the yarn.

[0015] The frame is provided with corresponding support shaft mounting holes for mounting the support shaft. The support shaft mounting holes are oblong or round holes. At least one of the two support pulleys and two transmission pulleys corresponding to each synchronous belt ring is mounted through the oblong holes. The positions of the support pulleys and transmission pulleys can be adjusted to tension the synchronous belt ring.

[0016] This invention achieves the following beneficial effects: by setting a motor mounting position on the frame corresponding to each spindle winding device to install the motor, and by supporting a single-sided toothed synchronous belt loop with every two toothless support pulleys to form a straight segment, the toothed surface of the synchronous belt loop faces outward and meshes with a toothed active synchronous belt pulley driven by the motor to rotate forward and backward, and by increasing the wrapping angle of the synchronous belt to the active synchronous belt pulley by supporting the inner side of the synchronous belt with the transmission pulley, the lateral drive of the single spindle yarn guide is realized. Furthermore, toothless pulleys can be used for the support pulleys, which is beneficial for the tension of the straight segment of the synchronous belt loop. The structure is simple and compact, reducing the material cost of the device. Attached Figure Description
