Description

Technical Field

[0001] The invention relates to a full-automatic wire cutting and stripping machine. Background Art

[0002] Cable wire products that have been wound and packaged usually need to have their ends peeled off when in use. The traditional wire stripping method is to first use a wire stripping device to circumscribe the wire skin, and then manually peel off the skin. All the force is applied by the operator based on their feelings, which can easily lead to the peeling force being too light to peel it off, or the peeling force being too heavy, resulting in the removal of layers that do not need to be peeled off. This is difficult and inefficient, so automatic wire stripping machines have emerged to replace manual stripping of the skin.

[0003] Existing automatic wire stripping machines generally only have one wire stripping knife, so stripping the wires at both ends requires two operations. In addition, due to the different wire length requirements, the wire breaking operation needs to be completed manually or with a separate wire breaking machine. This undoubtedly increases the labor intensity and equipment investment, complicates the process layout, and has a low degree of automation. Summary of the Invention

[0016] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0017] like Figures 1 to 3 The fully automatic wire cutting and stripping machine shown in the figure comprises a frame 1, a first traction mechanism 2 is provided on the left end of the frame 1, a second traction mechanism 3 with the same structure as the first traction mechanism 2 is provided on the right end of the frame 1, a wire stripping mechanism 4 is provided in the middle of the frame 1 between the first traction mechanism 2 and the second traction mechanism 3, and a wire cutting mechanism 5 is provided on the frame 1 opposite the wire stripping mechanism 4.

[0018] The first traction mechanism 2 has an upper transmission belt 2-1 and a lower transmission belt 2-2 that are parallel to each other and clamp the wire for movement. A pair of mutually meshing gears 2-4 are driven by a reversible driving motor 2-3 through belt transmission. The two gears 2-4 are respectively installed on the main pulley shafts of the upper transmission belt 2-1 and the lower transmission belt 2-2 to achieve synchronous operation of the upper transmission belt 2-1 and the lower transmission belt 2-2 to clamp the wire for movement.

[0019] In order to meet the requirements of wires with different wire diameters, a gap adjustment mechanism 6 for adjusting the gap between the upper transmission belt 2-1 and the lower transmission belt 2-2 is provided between the transmission frame of the upper transmission belt 2-1 and the transmission frame of the lower transmission belt 2-2. The gap adjustment mechanism comprises a gap adjustment motor and a screw rod rotatably mounted between the transmission frame of the upper transmission belt 2-1 and the transmission frame of the lower transmission belt 2-2. The gap adjustment motor rotates the screw rod through the belt transmission. A left-hand nut is provided in the transmission frame of the upper transmission belt 2-1, and a right-hand nut is provided in the transmission frame of the lower transmission belt 2-2. The left-hand nut and the right-hand nut are respectively connected to the screw rod for transmission. A spring is provided on each screw rod in the transmission frame of the upper transmission belt 2-1 and the transmission frame of the lower transmission belt 2-2 to play a buffering role during adjustment.

[0020] The wire stripping mechanism 4 has a base plate 4-1 fixed on the frame 1, and a mounting plate 4-2 is slidably provided on the base plate 4-1. A cylinder 4-3 and a slide rail 4-4 arranged parallel to the axis of the cylinder 4-3 are installed on the base plate 4-1. The piston rod of the cylinder 4-3 is fixedly connected to the bottom surface of the front end of the mounting plate 4-2, and the bottom surface of the mounting plate 4-2 is connected to a slider 4-5 that slides with the slide rail 4-4. Under the push of the cylinder 4-3, the mounting plate 4-2 can move forward or backward toward the direction of the wire breaking mechanism 5.

[0021] A pair of knife seats 4-6 are fixed at the inner end of the mounting plate 4-2, and a wire stripping knife 4-7 with its head facing oppositely is installed on the knife seat 4-6. The wire stripping knife 4-7 includes a cylindrical knife body and a guide sleeve. The guide sleeve is connected to the outer end face of the knife body by screws. The inner wall of the knife body is provided with a sheath stripping knife, an outer conductor stripping knife, an inner conductor chopping knife and an inner conductor chamfering knife in sequence, wherein one end of the inner conductor chamfering knife is fixed on the chamfering knife seat, and the chamfering knife seat is provided on the knife body.

[0022] A rotating shaft is provided on the inner end face of the knife body. The rotating shafts of the two wire stripping knives 4-7 are close to each other. Auxiliary friction cone wheels 4-8 are respectively installed on the rotating shafts. A wire stripping motor 4-9 is fixed to the outer end of the mounting plate 4-2. A main friction cone wheel 4-10 is installed on the output shaft of the wire stripping motor 4-9. The main friction cone wheel 4-10 synchronously drives the two auxiliary friction cone wheels 4-8, thereby driving the two wire stripping knives 4-7 to rotate and strip the wire.

[0023] The mounting plate 4-2 is also provided with a protective cover 4-11 ( Figure 1 、 Figure 2 The protective shields 4-11 were removed in Figure 3 A protective cover 4-11 is shown in the figure, and the wire stripping motor 4-9 is placed in the protective cover 4-11.

[0024] The wire cutting mechanism 5 includes a wire cutting saw blade 5 - 1 that can move forward or backward toward the wire stripping mechanism 4 .

[0025] Specifically, the wire-breaking mechanism 5 comprises a base plate 5-2 fixed to the frame 1, a lower plate 5-3 slidably mounted on the base plate 5-2, and an upper plate 5-4 slidably mounted on the lower plate 5-3. A lower cylinder 5-5 is mounted on the base plate 5-2 for pushing the lower plate 5-3 forward or backward, and an upper cylinder 5-6 is mounted on the lower plate 5-3 for pushing the upper plate 5-4 forward or backward. A wire-breaking saw blade 5-1 is mounted on one side of the inner end of the upper plate 5-4. A wire-breaking motor 5-7 is mounted on the outer end of the upper plate 5-4. The wire-breaking motor 5-7 drives the wire-breaking saw blade 5-1 to rotate via a belt. Short and long guide tubes 5-8 and 5-9 are respectively mounted on the lower plate 5-3 on either side of the wire-breaking saw blade 5-1. The short and long guide tubes 5-8 and 5-9 are coaxially arranged and relatively close to each other. A protective cover is located above the wire-breaking saw blade 5-1, and a chip chute is located below the wire-breaking saw blade 5-1.

[0026] A wire guide device 7 is further provided on the left side of the first traction mechanism 2. The wire guide device 7 has a bracket on which two rows of wire groove wheels are installed, and an adjusting handwheel is provided on the upper row of wire groove wheels. By turning the adjusting handwheel, the gap between the two rows of wire groove wheels can be adjusted to meet the needs of wires with different wire diameters.

[0027] When stripping the wire, the whole roll of wire is placed on the wire drum, and the wire is guided by the wire groove wheel of the wire device 7 and enters the first traction mechanism 2. The upper transmission belt 2-1 and the lower transmission belt 2-2 operate synchronously to clamp the wire and move it forward; the cylinder 4-3 pushes the mounting plate 4-2 forward in the direction of the wire breaking mechanism 5, so that the axis of the wire stripping knife 4-7 is consistent with the moving direction of the wire, and the wire head enters the previous wire stripping knife 4-7 through the guide sleeve of the wire stripping knife 4-7. The first traction mechanism 2 stops, and the wire stripping motor 4-9 drives the main friction cone wheel 4-10 to rotate, driving the auxiliary friction cone wheel 4-8 to rotate, and driving the wire stripping knife 4-7 to rotate. Using the principle of rotary cutting, the wire stripping knife 4-7 gradually completes all the requirements required for stripping, such as stripping the sheath, stripping the outer conductor, splitting the inner conductor and chamfering the copper core inner conductor, thereby completing the stripping process at the front end of the wire.

[0028] Afterwards, the wire stripping motor 4-9 stops running, and the first traction mechanism 2 runs in the opposite direction, pulling the wire and then withdrawing the previous wire stripping knife 4-7. The cylinder 4-3 pushes the mounting plate 4-2 to drive the wire stripping knife 4-7 back to its original position, and the lower cylinder 5-5 acts to push the short tube 5-8 and the long tube 5-9 forward to be coaxial with the moving direction of the wire. The first traction mechanism 2 runs forward again, and after the wire passes through the short tube 5-8 and the long tube 5-9, its head enters the second traction mechanism 3 and is clamped and continues to move forward until the wire length reaches the required requirement. The first traction mechanism 2 and the second traction mechanism 3 tighten the wire and then stop. The wire breaking motor 5-7 drives the wire breaking saw blade 5-1 to rotate, and the upper cylinder 5-6 acts to push the wire breaking saw blade 5-1 forward to the wire to cut the wire.

[0029] Then the first traction mechanism 2 stops, and the second traction mechanism 3 continues to move, pulling the wire forward until it is pulled out of the long guide tube 5-9. The lower cylinder 5-5 moves to return the wire breaking mechanism 5 as a whole to its original position. The cylinder 4-3 pushes the mounting plate 4-2 forward again toward the wire breaking mechanism 5, so that the axis of the next wire stripping knife 4-7 is aligned with the direction of wire movement. The second traction mechanism 3 rotates in the reverse direction, feeding the wire head at the broken end through the guide sleeve into the next wire stripping knife 4-7. The second traction mechanism 3 stops, and the wire stripping motor 4-9 drives the main friction cone wheel 4-10 to rotate, driving the secondary friction cone wheel 4-8 to rotate, driving the wire stripping knife 4-7 to complete the stripping process at the rear end of the wire. Finally, the second traction mechanism 3 rotates in the forward direction, feeding the broken and stripped wire out of the wire breaking and stripping machine.

[0030] The present invention completes the wire stripping at both ends of the wire by the two wire stripping knives 4-7 of the wire stripping mechanism 4 acting successively, and cooperates with the wire breaking mechanism 5 in the middle to cut the wire, thereby completing the wire stripping at both ends of the wire and the wire breaking operation according to the length requirement at one time, thereby realizing the fully automatic operation of wire breaking and stripping, reducing the working intensity and improving the working efficiency.

[0031] With the above-described preferred embodiments of the present invention as inspiration, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
