AI Technical Summary
In existing flat knitting machines, the winding wheel can easily loosen the clamping wheel when driving the steel wire, resulting in the steel wire not being fully tightened. This affects the stability of threading and winding, especially after long-term operation or after changing to different thicknesses of steel wire, which makes it impossible to guarantee the clamping effect between the meshing pressure wheel and the wire clamping roller.
An automatic wire feeding winch drive device was designed. The clamping force of the pressure wheel is adjusted by the hinge rod and control components. Combined with one-way gear transmission, the stability of the wire is ensured during the winding and unwinding process. The clamping force is adjusted by a spring and screw structure to meet the needs of wires of different thicknesses.
It achieves stable winding and unwinding of steel wire under different working conditions, ensuring stable and reliable operation of steel wire in the flat knitting machine, reducing maintenance costs and improving the service life of the equipment.

Description
Technical Field
[0001] This utility model relates to the field of flat knitting machine technology, and more specifically, it relates to a winch drive device for automatically threading steel wire plates. Background Technology
[0002] Existing flat knitting machines require a wire threading structure. The wire is driven through this structure to pass through the corresponding through hole in the threading plate. The wire is pre-wound on a winding wheel, and then a motor drives the winding wheel to rotate clockwise or counterclockwise, thereby driving the wire to pass through the through hole in the threading plate for threading or take-up. In actual use, because the winding wheel is driven by a motor to rotate, it rotates during both threading and take-up. The wire locking device is only achieved by a set of pressure wheels, which are prone to loosening. This prevents the entire wire from being fully taut, causing the wire to slip relative to the winding wheel. Consequently, the wire cannot be threaded or taken up properly, and the stability and reliability of threading and take-up cannot be guaranteed.
[0003] The technical features of the automatic wire threading device disclosed in Chinese Patent Announcement No. CN111962202B are as follows: It includes a housing; a set of wire threading plates is arranged on the upper crossbeam of the housing; the wire threading needles on the wire threading plates have through-holes; all the wire threading holes of the needles are arranged in a straight line; a guide wire threading plate is arranged on one side of the upper crossbeam of the housing; a guide wire channel is arranged on the outer periphery of the guide wire threading plate; a drive mounting frame is arranged in the lower area of the housing corresponding to the guide wire threading plate; a drive mounting frame is provided with a drive motor, a take-up reel, and a wire pressing roller; the output end of the drive motor is connected to a transmission shaft; a first one-way bearing and a second one-way bearing are sleeved on the transmission shaft; the first one-way bearing and the second one-way bearing rotate in opposite directions.
[0004] The above technical solution enables the wire threading process to be driven by the motor in one direction to take-up gear and threading gear, ensuring stable and reliable operation of take-up and threading, and guaranteeing the stable and reliable operation of the flat knitting machine. However, after long-term operation or after changing to different thicknesses of steel wire, it is impossible to guarantee that the meshing pressure roller and the wire clamping roller can always clamp the steel wire, thus making it impossible to guarantee stable unwinding of the steel wire.
[0005] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

When the steel rope is used for a long time or when different thicknesses of steel rope are replaced, the deflection angle of the hinge rod can be adjusted by the control component to ensure the clamping force on the steel rope, thereby ensuring its stability during winding and unwinding. The first clamping wheel is driven to rotate by the drive component to drive the steel rope to unwind. After the flat knitting machine finishes its work, the take-up reel is driven to rotate by the drive component to wind the steel rope. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the accompanying drawings.
[0021] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0022] As shown in the figure, an automatic wire mesh winch drive device includes a housing 1. A winding reel 2 and a first pressure roller 3 are rotatably connected to one side surface of the housing 1. Hinges 4 are provided on both sides of the bottom of the housing 1. Hinges 5 are hinged to the hinges 4. A second pressure roller 6 is rotatably connected between the two hinges 5. The device also includes a control component for controlling the deflection angle of the hinges 5. A drive component for driving the winding reel 2 and the first pressure roller 3 is provided on one side of the housing 1.
[0023] During the steel rope threading process, the steel rope is wound on the take-up reel 2, with its end passing between the first clamping wheel 3 and the second clamping wheel 6. Under the action of the control component, the first clamping wheel 3 and the second clamping wheel 6 clamp the steel rope. When working for a long time or changing steel ropes of different thicknesses, the deflection angle of the hinge rod 5 can be adjusted by the control component to adjust the clamping force on the steel rope, thereby ensuring its stability during winding and unwinding. The first clamping wheel 3 is driven to rotate by the drive component to drive the steel rope to unwind. After the flat knitting machine finishes its work, the take-up reel 2 is driven to rotate by the drive component to wind the steel rope.
[0024] A hinge rod 5 has an extension 7 at one end away from the hinge axis 4. A horizontally arranged connecting rod 8 is provided on one side of the extension 7. One end of the connecting rod 8 has a through hole penetrating its upper and lower surfaces. The control component includes a vertically arranged screw 9, which passes through the through hole and is threaded to the bottom of the housing 1.

The two ends of the spring 11 are fixedly connected to the bottom of the connecting rod 8 and the top of the abutment block 10.
[0025] Under normal conditions, spring 11 is in a compressed state. Under the elastic force of spring 11, the hinge rod 5 has an upward movement tendency, causing the second clamping wheel 6 to press against the bottom of the first clamping wheel 3, thereby effectively clamping the steel rope. The end surface of the abutment block 10 is provided with an adjustment groove so as to drive the screw 9 to rotate, thereby adjusting the compression of spring 11 and adjusting the clamping force of the steel rope to ensure smooth winding and unwinding of the steel rope under different working conditions.
[0026] The bottom of the housing 1 has a slot 12 for inserting the top of the screw. The inner walls on both sides of the slot 12 have guide grooves 13. A positioning block 14 is inserted into the guide groove 13. The positioning block 14 has a threaded through groove for the screw 9 to pass through and be threaded. When the threaded through groove of the positioning block is damaged, the positioning block can be replaced separately without replacing the entire housing 1, thus saving on later maintenance costs.
[0027] The drive unit includes a motor 15 mounted on one side of the housing 1. A first one-way gear 16 is mounted on the output shaft of the motor 15. A second gear 17 meshing with the first one-way gear 16 is provided on the side wall of the take-up reel 2. A third one-way gear 18 is also provided on the output shaft of the motor 15. The direction of rotation of the third one-way gear 18 is opposite to that of the first one-way gear 16. A fourth gear 19 meshing with the third one-way gear 18 is provided at the end of the first pressure roller 3. A fifth gear 20 meshing with the fourth gear is provided at the end of the second pressure roller 6.
[0028] Arc-shaped grooves are provided on both sides of the first clamping wheel 3 and the second clamping wheel 6 on one side surface of the housing 1. A positioning plate 21 is also fixedly connected to one side surface of the housing 1. An arc-shaped plate 22 is provided at the end of the positioning plate 21. A limiting groove is formed between the arc-shaped plate 22 and the arc-shaped groove. A steel wire guide tube 23 for the steel rope to pass through is inserted and fixed in the limiting groove to further improve the stability of the steel rope during the winding and unwinding process.
[0029] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
