DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a wire changing device for a medium drawing machine, comprising a base 1 and a clamping mechanism 2, wherein the clamping mechanism 2 is provided on one side of the surface of the base 1, and an adjustment mechanism 3 is provided at one end of the clamping mechanism 2;

[0021] The clamping mechanism 2 includes a slide 201, a limiting groove 202, a servo motor 203, a bidirectional screw rod 204, a slider 205, a limiting block 206, a support column 207 and a clamping block 208. A slide 201 is provided on one side of the surface of the base 1, a limiting groove 202 is provided inside the base 1, a servo motor 203 is installed on one side of the surface of the base 1, a bidirectional screw rod 204 is provided inside the slide 201, one end of the bidirectional screw rod 204 passes through a slider 205, both sides of the surface of the slider 205 are fixedly connected to the limiting block 206, the top of the slider 205 is fixedly connected to the support column 207, and the top of the support column 207 is fixedly connected to the clamping block 208. Through the arrangement of the slide 201, the limiting groove 202, the servo motor 203, the bidirectional screw rod 204, the slider 205, the limiting block 206, the support column 207 and the clamping block 208, when in use, when it is necessary to change the line, the servo motor 203 is turned on at this time, The servo motor 203 drives the bidirectional screw rod 204 to rotate. Since the slider 205 is embedded in the inside of the slide groove 201 and the slider 205 is threadedly sleeved on the surface of the bidirectional screw rod 204, and the limit block 206 is embedded in the inside of the limit groove 202, when the bidirectional screw rod 204 rotates, the two sets of sliders 205 move away from each other along the bidirectional screw rod 204 inside the slide groove 201, and the limit block 206 slides inside the limit groove 202, so that the slider 205 drives the two sets of clamping blocks 208 to move away from each other through the support column 207. At this time, the clamping block 208 loses its clamping effect on the spool and replaces the new spool. Then the servo motor 203 is controlled to drive the bidirectional screw rod 204 to rotate in the opposite direction. At this time, the sliders 205 move towards each other, thereby driving the clamping block 208 to move towards each other through the support column 207. At this time, the two sets of clamping blocks 208 moving towards each other clamp the new spool.

[0022] Furthermore, the slide groove 201 is connected to the limiting groove 202, and the limiting groove 202 is a dovetail groove. Through the setting of the slide groove 201, when in use, the slide groove 201 provides a movable space for the slider 205 to move.

[0023] Furthermore, the output end of the servo motor 203 is connected to the bidirectional screw rod 204, and the slider 205 is embedded in the inside of the slide groove 201. Through the setting of the servo motor 203, when in use, the servo motor 203 can drive the bidirectional screw rod 204 to rotate inside the slide groove 201.

[0024] Furthermore, the slider 205 is threadedly sleeved on the surface of the bidirectional screw rod 204, and the limit block 206 is a dovetail block, which is embedded in the inside of the limit groove 202. Through the setting of the limit block 206, when in use, the limit block 206 of the dovetail block is embedded in the inside of the limit groove 202 of the dovetail groove to limit the moving direction of the slider 205, thereby preventing the slider 205 from rotating with the bidirectional screw rod 204.

[0025] Furthermore, the adjusting mechanism 3 includes a threaded hole 301, a telescopic rod 302, a screw 303, a rotating knob 304, a fitting block 305, a fixed block 306, a fitting groove 307 and a ball 308. A threaded hole 301 is provided on one side of the surface of the clamping block 208, and the inner wall of the clamping block 208 is fixedly connected to the telescopic rod 302. The screw 303 runs through the interior of the threaded hole 301, one end of the screw 303 is fixedly connected to the rotating knob 304, and the other end of the screw 303 is fixedly connected to the fitting block 305, and the other end of the telescopic rod 302 is fixedly connected to the fixed block 306. The interior of the fixed block 306 is provided with a fitting groove 307, and the inner wall of the fixed block 306 is installed with a ball 308. When the screw 303 is screwed to the clamping block 208 through the threaded hole 301, and the fitting block 305 connected to one end of the screw 303 is fitted into the fitting groove 307 provided inside the fixing block 306, one end of the telescopic rod 302 is fixedly connected to the clamping block 208, and the other end is fixedly connected to the fixing block 306. When the screw 303 is rotated, the fitting block 305 rotates inside the fitting groove 307 and drives the fixing block 306 to move, and the telescopic rod 302 performs telescopic movement. The fixing block 306 is moved to the appropriate position as needed. At this time, the fixing block 306 of the arc block clamps and fixes the new spool, and the ball 308 can keep the spool rotating smoothly when clamped by the fixing block 306.

[0026] Furthermore, the screw rod 303 is threadedly connected to the clamping block 208 through the threaded hole 301. The engaging block 305 is a cylindrical block. Through the arrangement of the screw rod 303, when in use, the screw rod 303 can drive the engaging block 305 to move when it rotates.

[0027] Furthermore, the interlocking block 305 is interlocked in the interlocking groove 307, the interlocking groove 307 is a cylindrical groove, and the fixed block 306 is an arc-shaped block. Through the setting of the interlocking block 305, when in use, the interlocking block 305 follows the screw 303 to rotate inside the interlocking groove 307, and at the same time, the interlocking block 305 can drive the fixed block 306 to move.

[0028] Working principle: When the line changing operation is required, the servo motor 203 is turned on, and the servo motor 203 works to drive the bidirectional screw rod 204 to rotate. Since the slider 205 is embedded in the inside of the slide groove 201 and the slider 205 is threaded on the surface of the bidirectional screw rod 204, and the limit block 206 is embedded in the inside of the limit groove 202, when the bidirectional screw rod 204 rotates, the two sets of sliders 205 move away from each other along the bidirectional screw rod 204 inside the slide groove 201, and the limit block 206 slides inside the limit groove 202, so that the slider 205 drives the two sets of clamping blocks 208 to move away from each other through the support column 207. At this time, the clamping block 208 loses its clamping effect on the spool, and the new spool is replaced. Then the servo motor 203 is controlled to drive the bidirectional screw rod 204 to rotate in the opposite direction. At this time, the sliders 205 move towards each other, thereby driving the clamping blocks 208 to move towards each other through the support column 207. When the screw 303 is screwed to the clamping block 208 through the threaded hole 301, and the interlocking block 305 connected to one end of the screw 303 is engaged with the inside of the interlocking groove 307 provided in the fixing block 306, at the same time, one end of the telescopic rod 302 is fixedly connected to the clamping block 208, and the other end is fixedly connected to the fixing block 306. Therefore, when the screw 303 rotates, the interlocking block 305 rotates inside the interlocking groove 307 and drives the fixing block 306 to move. At the same time, the telescopic rod 302 performs telescopic movement, and the fixing block 306 is moved to the appropriate position as needed. At this time, the fixing block 306 of the arc block clamps and fixes the new spool, and the ball 308 can keep the spool rotating smoothly when clamped by the fixing block 306.
