[0002] Braiding is a cable processing technology that provides one or more layers of protection for wires and cables. Braiding machine wires are generally divided into two major types of materials: non-metallic and metallic. Non-metallic braiding generally refers to fiber braiding machines, which mainly provide a light protective layer for cables to protect them from or reduce damage from various erosions such as light, heat, moisture, low temperature, acid and alkali gases, and external mechanical forces. Metal materials are mainly braided with copper wire, tinned copper, steel wire, etc., and their main functions are: magnetic field shielding and electromagnetic interference prevention.

DETAILED DESCRIPTION

[0031] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0032] Reference Figures 1 to 8 As shown, a cable braiding machine provided by an embodiment of the present invention comprises a frame 100, a braiding mechanism and an adjusting mechanism. The braiding mechanism is arranged on the frame 100, and is used to braid a braiding shell 110 on the outer peripheral wall of the cable.

[0033] The adjustment mechanism includes a connecting tube 200, an extrusion assembly, and two adjustment assemblies. The connecting tube 200 is arranged on the frame 100 along a first direction, the first direction being a horizontal direction, and a first channel 210 arranged along the first direction is opened in the connecting tube 200. The two ends of the connecting tube 200 are respectively a first end and a second end, and the cable with the braided shell 110 passes through the first channel 210 and moves along the direction from the first end to the second end of the connecting tube 200.

[0034] Two first slide grooves 220 are provided in the connecting tube 200, and the two first slide grooves 220 are sequentially distributed along the up-down direction. Each adjustment component is arranged in a first slide groove 220, and each adjustment component includes a connecting chain 300 and a plurality of movable blocks 310, the connecting chain 300 is annular, and the connecting chain 300 is arranged along the direction in which the first slide groove 220 extends, and the connecting chain 300 circulates along the direction from the first end of the connecting tube 200 to the second end and then to the first end, and the movable block 310 is fixedly arranged on the connecting chain 300, and the plurality of movable blocks 310 are sequentially distributed along the circumference of the connecting chain 300.

[0035] The connecting tube 200 is provided with two through-slot assemblies, which are sequentially distributed along the up-down direction, and each through-slot assembly includes a plurality of mounting slots, which are sequentially distributed along the first direction, and each mounting slot is connected to the first slide slot 220 and the first channel 210. The extrusion assembly includes a plurality of extrusion blocks 380 and a plurality of reset units, and each extrusion block 380 is arranged in a mounting slot, and the extrusion block 380 is arc-shaped, and the concave surface of the arc faces the cable. After the movable block 310 contacts the extrusion block 380, the extrusion block 380 is driven to move in the direction close to the cable, and the movable block 310 can drive the extrusion block 380 to move in the direction from the first end to the second end of the connecting tube 200. After the movable block 310 and the extrusion block 380 are out of contact, the reset unit drives the extrusion block 380 to reset.

[0036] The connecting chain 300 is driven to rotate, and the connecting chain 300 drives all the movable blocks 310 to move. After the movable block 310 contacts the extrusion block 380, the movable block 310 presses the extrusion block 380, so that the extrusion block 380 moves toward the direction close to the axis of the connecting tube 200. And because the extrusion block 380 is arc-shaped, and the concave surface of the arc faces the cable, the extrusion block 380 squeezes the braided shell 110 flat, flattens the protrusions produced by the braided shell 110, and straightens the cable, so that the braided shell 110 is more uniform and the braiding effect is improved.

[0037] When the movable block 310 moves, the movable block 310 in contact with the extrusion block 380 drives the extrusion block 380 to move synchronously for a distance. The extrusion block 380 drives the cable to be transported a distance toward the second end of the connecting tube 200 while flattening the braided shell 110. Finally, the movable block 310 moves relative to the extrusion block 380 and disengages from the contact. The extrusion block 380 is quickly reset under the action of the reset unit, and the sliding friction between the extrusion block 380 and the braided shell 110 is small, thereby reducing the wear on the braided shell 110, thereby improving the braiding molding effect. And reduce the wear on the extrusion block 380, extend the service life of the extrusion block 380, and at the same time do not affect the molding effect of the extrusion block 380.

[0038] In this embodiment, the first sliding grooves 220 are arranged obliquely, and along the direction from the first end to the second end of the connecting tube 200, the two first sliding grooves 220 gradually approach each other.

[0039] Since the first slide groove 220 is arranged obliquely, the two first slide grooves 220 gradually approach each other along the direction from the first end to the second end of the connecting tube 200. Therefore, the two extrusion blocks 380 that are opposite to each other in the upper and lower directions at the contact point with the newly woven braided shell 110 are far away, which facilitates the newly woven braided shell 110 to enter the first channel 210. In the process of the braided shell 110 gradually moving toward the second end of the first channel 210, the closer the distance between the two extrusion blocks 380 that are opposite to each other in the upper and lower directions, the greater the clamping force of the extrusion blocks 380 on the cable. Therefore, the gradually increasing clamping force has less impact on the cable braiding process without changing the clamping effect, thereby making the braided shell more uniform.

[0040] In this embodiment, two guide channels 211 are provided in each first slide groove 220, and the two guide channels 211 are sequentially distributed along the second direction, the second direction is a horizontal direction, and the second direction is perpendicular to the first direction. Each guide channel 211 includes a first slant groove 212, a second slant groove 213 and two first arc grooves 214.

Along the direction from the first end to the second end of the connecting tube 200, the first slant groove 212 and the second slant groove 213 gradually approach the axis of the connecting tube 200. The two first arc grooves 214 are sequentially distributed along the first direction, and the concave surfaces of the two first arc grooves 214 are arranged oppositely. The two ends of the first slant groove 212 are respectively connected to one end of the two first arc grooves 214. The two ends of the second slant groove 213 are respectively connected to the other end of the two first arc grooves 214.

A spiral groove 331 is provided in the adjusting tube 330, and one end of the connecting rod 320 in the second chute 213 extends out of the second chute 213 and is slidably arranged in the spiral groove 331.

[0044] When the adjusting tube 330 rotates, the adjusting tube 330 drives the movable block 310 in the second slanted groove 213 to move along the direction from the first end to the second end of the connecting tube 200. Since the movable block 310 is fixed on the connecting chain 300, the connecting chain 300 rotates and drives all the movable blocks 310 to rotate.

When the movable block 310 in the second inclined groove 213 moves, the movable block 310 in contact with the extrusion block 380 drives the extrusion block 380 to move synchronously for a distance. When the movable block 310 and the extrusion block 380 are out of contact, the extrusion block 380 is reset under the action of the first spring 360 and the second spring 370.

A plurality of fixing rods are arranged on each rotating disk 410, and a plurality of fixing rods are distributed in sequence along the circumference of the rotating disk 410. Multiple connecting shafts are distributed in sequence along the circumference of the mounting tube 400, and the connecting shafts are arranged along the first direction. The connecting shafts are located between two adjacent fixed rods on the rotating disk 410, and under the push of the fixed rods, the connecting shafts slide around the circumference of the multiple rotating disks 410 in sequence, and each wire wheel 420 is rotatably arranged on a connecting shaft.

[0050] A second gear is fixedly arranged on each rotating disk 410, and the braiding mechanism also includes a second gear ring and a second motor, the second motor is fixedly arranged on the frame 100, and a third gear is fixedly arranged on the output shaft of the second motor.

Start the second motor, the second motor drives the second gear ring to rotate through the third gear, and the second gear ring drives multiple rotating disks 410 to rotate synchronously. When one of the rotating disks 410 rotates, the fixed rod on one rotating disk 410 drives the connecting shaft to rotate synchronously until the connecting shaft meets the fixed rod on another rotating disk 410, and the connecting shaft comes to the next rotating disk 410. Multiple connecting shafts continuously slide around the circumference of multiple rotating disks 410. The braided wire on the wire wheel 420 is woven on the cable to form a braided shell 110.

[0051] In this embodiment, a cable braiding machine further includes a traction mechanism, which includes a reel, which is arranged along the second direction and can be rotatably arranged around its own axis on the frame 100. The reel is at the second end of the connecting cylinder 200, and the cable is wound around the reel.

[0052] In this embodiment, the traction mechanism further includes a traction motor, which is fixedly disposed on the frame 100, and the output shaft of the traction motor is fixedly connected to the drum.

[0053] Working process: The cable is passed through the installation cylinder 400 and the connecting cylinder 200 in sequence and wound on the reel. The traction motor is started, and the cable is wound on the reel when the reel rotates, and the cable is driven to move in the direction from the first end to the second end of the connecting cylinder 200.

[0054] At the same time, the second motor is started, and the second motor drives the second gear ring to rotate through the third gear, and the second gear ring drives multiple rotating disks 410 to rotate synchronously. When one of the rotating disks 410 rotates, the fixed rod on one rotating disk 410 drives the connecting shaft to rotate synchronously until the connecting shaft meets the fixed rod on another rotating disk 410, and the connecting shaft comes to the next rotating disk 410. The multiple connecting shafts continuously slide around the circumference of the multiple rotating disks 410. The braided wire on the wire wheel 420 is braided on the cable to form a braided shell 110.

[0055] At the same time, the first motor is started, the first motor drives the first gear to rotate, and the first gear drives the adjustment tube 330 to rotate through the first gear ring. Since one end of the connecting rod 320 in the second inclined groove 213 is in the spiral groove 331, when the adjustment tube 330 rotates, the adjustment tube 330 drives the movable block 310 in the second inclined groove 213 to move along the direction from the first end to the second end of the connecting tube 200. Since the movable block 310 is fixed on the connecting chain 300, the connecting chain 300 rotates and drives all the movable blocks 310 to rotate.

[0056] When the braiding shell 110 is braiding, due to the different angles between the multiple wheel 420 and the cable, and the different tightness of the braiding wire wrapped on the wheel 420, the braiding shell 110 may produce unevenness in a specific direction, the braiding shell 110 may produce bulges or depressions, and the whole may be partially bent relative to the cable.

[0057] When the movable block 310 in the second inclined groove 213 contacts the extrusion block 380, the movable block 310 presses the extrusion block 380, so that the extrusion block 380 moves toward the axis of the connecting tube 200, and the second spring 370 is compressed. The extrusion block 380 contacts the braided shell 110, and because the extrusion block 380 is arc-shaped, and the concave surface of the arc faces the cable, the extrusion block 380 squeezes the braided shell 110 flat, flattens the protrusions produced by the braided shell 110, and straightens the cable, so that the braided shell 110 is more uniform and the braiding effect is improved.

[0058] When the movable block 310 in the second slant slot 213 moves, the movable block 310 in contact with the extrusion block 380 drives the extrusion block 380 to move synchronously for a distance. The extrusion block 380 flattens the braided shell 110 and drives the cable to be transported to the second end of the connecting tube 200 for a distance.

[0059] Since the first slide groove 220 is arranged obliquely, the two first slide grooves 220 gradually approach each other along the direction from the first end to the second end of the connecting tube 200. Therefore, the two extrusion blocks 380 that are opposite to each other in the upper and lower directions at the contact point with the newly woven braided shell 110 are far away, which facilitates the newly woven braided shell 110 to enter the first channel 210. In the process of the braided shell 110 gradually moving toward the second end of the first channel 210, the closer the distance between the two extrusion blocks 380 that are opposite to each other in the upper and lower directions, the greater the clamping force of the extrusion blocks 380 on the cable. Therefore, the gradually increasing clamping force has less impact on the cable braiding process without changing the clamping effect, thereby making the braided shell more uniform.

[0060] When the movable block 310 and the extrusion block 380 are out of contact, the extrusion block 380 is reset under the action of the first spring 360 and the second spring 370. The extrusion block 380 is quickly reset under the action of the reset unit, and the sliding friction between the extrusion block 380 and the braided shell 110 is small, thereby reducing the wear on the braided shell 110 to improve the braiding molding effect. It also reduces the wear on the extrusion block 380 and extends the service life of the extrusion block 380, while not affecting the molding effect of the extrusion block 380.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
