Description

Technical Field

[0001] The utility model relates to the technical field of wire drawing machines, in particular to a flexible yarn breaking and connecting mechanism for a glass fiber wire drawing machine. Background Art

[0002] Glass fiber drawing machine is a mechanical equipment that draws molten glass into fiber filaments at high speed and winds them into fiber rolls according to a certain pattern.

[0003] At present, in the glass fiber drawing machine on the market, a certain amount of yarn will be entangled between the yarn rolls during the drawing process. After the drawing is completed, before the yarn rolls are unloaded, the yarns connecting the yarn rolls need to be cut off. In the prior art, most factories directly use manual yarn cutting. Although the operation is convenient, the manual operation increases the labor intensity of the workers, resulting in a decrease in the overall production efficiency of glass fiber drawing. Some glass fiber drawing factories use a solution that uses a mechanical structure to drive the yarn cutting knife to automatically cut the continuous yarn. However, when the yarn cutting knife cuts the continuous yarn, because it is mechanically controlled, its strength is difficult to control, which often causes the yarn cutting knife to cut the impeller, resulting in cut marks on the impeller surface, affecting the service life of the impeller. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a flexible yarn breaking and connecting mechanism for a glass fiber drawing machine.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a flexible yarn breaking mechanism for a glass fiber drawing machine, comprising a swing rod rotatably arranged on a drawing machine base plate, one end of the swing rod is arranged in a drawing machine frame and a driving mechanism is arranged at the end, and the other end extends horizontally toward the front end of an impeller, a plurality of swing arms are arranged at intervals on the swing rod, a fixed frame is arranged at the suspended end of the swing arm, a yarn cutting rope is arranged in the vertical plane of the fixed frame, and the driving mechanism drives the swing rod to rotate and drives the swing arm to swing so that the yarn cutting rope moves toward or away from the impeller.

[0006] By adopting the above technical scheme, a swing rod, a driving mechanism, a swing arm, a fixed frame and a yarn cutting rope are provided. The swing rod is driven to rotate by the driving mechanism, thereby driving the swing arm and the fixed frame to swing, so that the yarn cutting rope contacts the continuous yarn, and then the continuous yarn is driven to rotate by the rotation of the impeller, so that the continuous yarn is cut by the yarn cutting rope under high-speed rotation. The yarn cutting rope contacts the impeller in a flexible manner, which reduces the damage to the impeller caused by the rigid contact between the traditional yarn cutting knife and the impeller, and extends the service life of the impeller.

[0007] Furthermore, the fixing frame is in an overall bow shape, and a tensioner and an adjuster are respectively provided at two ends thereof, and the two ends of the yarn cutting rope are respectively connected to the tensioner and the adjuster.

[0008] By adopting the above technical solution, a tensioner and an adjuster are respectively arranged at both ends of the fixing frame. When the yarn cutting rope becomes loose after long-term use, the tightness of the yarn cutting rope is adjusted by the tensioner and the adjuster to keep the yarn cutting rope in a tensioned state.

[0009] Furthermore, the swing arm includes an arm body and a mounting block. A semicircular groove is provided at one end of the arm body adjacent to the swing rod, and a semicircular groove is also correspondingly provided on the mounting block.

[0012] By adopting the above technical scheme, a fixed seat, a first hinge shaft, a mounting seat, a driving motor, a screw rod, a nut sliding seat, a connecting block and a second hinge shaft are provided. The mounting seat is hinged to the fixed seat through the first hinge shaft, so that the angle of the output shaft of the driving motor can be changed. The screw rod is driven to rotate by the driving motor, thereby pushing the nut sliding seat to slide on the screw rod, so that the connecting block hinged to it rotates along the core of the swing rod, thereby driving the swing rod to rotate.

[0013] Furthermore, a limit frame is arranged on the frame, and a limit column is arranged on the limit frame below the connecting block.

The swing rod 10 is rotatably arranged on a base plate of the drawing machine, one end of the swing rod 10 is arranged in a frame of the drawing machine and a driving mechanism 40 is arranged at the end, and the driving mechanism 40 is used to drive the swing rod 10 to rotate; the other end of the swing rod 10 extends horizontally toward the front end of the impeller, and the swing arm 20 is arranged on the rod body of the swing rod 10 outside the base plate at intervals, the fixing frame 30 is arranged at the suspended end of the swing arm 20, and the yarn cutting rope 31 is arranged in the vertical plane of the fixing frame 30, and the driving mechanism 40 drives the swing rod 10 to rotate and drives the swing arm 20 to swing so that the yarn cutting rope 31 contacts the impeller to cut the continuous yarn.

[0025] The driving mechanism 40 includes a fixed seat 41 arranged on the frame of the wire drawing machine, and a mounting seat 43 is hingedly arranged on the fixed seat 41 through a first hinge shaft 42, and the first hinge shaft 42 is parallel to the swing rod 10. A driving motor 44 is fixedly arranged on the mounting seat 43, and the axis core of the output shaft of the driving motor 44 is perpendicular to the rod core of the swing rod 10, so that the output shaft of the driving motor 44 rotates in a plane perpendicular to the swing rod 10. The output shaft of the driving motor 44 passes through the mounting seat 43 and is coaxially provided with a screw rod 45, and a nut sliding seat 46 is spirally arranged on the screw rod 45. A connecting block 47 is fixedly arranged at one end of the swing rod 10 located in the frame, and the connecting block 47 and the nut sliding seat 46 are hinged through a second hinge shaft 48, and the second hinge shaft 48 is parallel to the first hinge shaft 42. In this way, the screw rod 45 is driven to rotate by the driving motor 44, and the nut sliding seat 46 is driven to move on the screw rod 45, so that the connecting block 47 rotates along the rod core of the swing rod 10, thereby driving the swing rod 10 to rotate.

[0026] During the specific setting, a plurality of swing arms 20 are provided, and the specific number is the same as the number of yarn rolls on the impeller. One of the swing arms 20 is located in the area between the yarn roll and the winding ring, and the remaining swing arms 20 are respectively arranged in the area between the yarn rolls and the yarn rolls.
