Description
Technical Field
[0001] The utility model relates to the technical field of wire processing, and particularly relates to an efficient wire cutting device. Background Art
[0002] An electric wire is composed of one or several soft conductors, with a soft protective layer wrapped outside; a cable is composed of one or several insulated conductors, with a tough outer layer made of metal or rubber wrapped outside. Electric wires and cables are composed of four parts: a conductor, an insulating layer, a shielding layer, and a protective layer. The conductor is the conductive part of the electric wire and cable, used to transmit electric energy, and is the main part of the electric wire and cable. The insulating layer electrically isolates the conductor from the ground and between conductors of different phases, ensuring the transmission of electric energy, and is an indispensable part of the structure of the electric wire and cable. The shielding layer, electric wires and cables of 15KV and above generally have a conductor shielding layer and an insulating shielding layer. The protective layer serves to protect the electric wire and cable from the intrusion of external impurities and moisture, and to prevent direct damage to the power cable by external forces. During the processing of electric wires and cables, it is often necessary to feed the material forward and cut it into the same length one by one due to production and installation needs. Currently, this work is completed manually, which not only has a large manual labor intensity but also has a low production efficiency, and there are significant differences in the lengths of the electric wires.
[0003] The patent number CN201720770073.8 discloses an electric wire feeding and cutting device, belonging to the technical field of electric wire processing. It includes an unwinding mechanism and a feeding and cutting mechanism. The unwinding shaft of the unwinding mechanism can rotate on the unwinding support, and the wire reel is installed on the unwinding shaft. The feeding slider of the feeding and cutting mechanism can slide on the guide rail. The left end of the feeding piston rod of the feeding cylinder is connected to the feeding slider. The fixed clamp is installed on the feeding slider through a fastening screw. A lower clamping groove is provided at the left end of the fixed clamp. The movable clamp is hinged to the straight support plate and the L-shaped support plate through a clamp pin shaft. An upper clamping groove is provided at the left end of the movable clamp. The lower end of the clamping piston rod of the clamping cylinder is connected to the right end of the fixed clamp. The wire guiding seats are arranged side by side on the feeding slider. The upper cutting knife is installed at the lower right side of the movable clamp, and the lower cutting knife is installed at the lower right side of the fixed clamp. The utility model realizes continuous feeding of the electric wire and realizes cutting, with a reasonable structure, and the lengths of the cut electric wires are unified. When this disclosed patent works, the upper cutting knife 18 moves downward, and the electric wire is cut under the action of the upper cutting knife 18 and the lower cutting knife 19. At this time, the feeding slider 8 touches the right travel switch 29, controlling the feeding piston rod 22 of the feeding cylinder 9 to drive the feeding slider 8 to move leftward and return to the starting position for the next cycle. The upper cutting knife 18 needs to move up and down a certain distance to cut the electric wire once, and when cutting, the electric wire stops being fed. Only after the current cutting is completed can the electric wire continue to be fed, paused, and cut again. This cutting method has a low efficiency. Therefore, the utility model proposes an efficient wire cutting device. Content of the Utility Model
[0004] In order to overcome the deficiencies in the prior art, an embodiment of the present utility model provides an efficient wire cutting device to solve the problems raised in the above-mentioned background art.
[0005] An embodiment of the present application discloses: an efficient wire cutting device, including a cutting table and a fixing plate vertically arranged on the cutting table. Two wire guiding pulleys for guiding wires are arranged up and down on the front surface of the fixing plate. A deviation correction groove with a U-shaped cross-section is arranged on one side of the two wire guiding pulleys. A receiving conveyor belt is arranged on one side of the deviation correction groove. A rotating shaft perpendicular to the plate surface is arranged above the deviation correction groove on the fixing plate. The rotating shaft is driven by a servo motor. A cutter perpendicular to the rotating shaft is fixed on the rotating shaft. The cutter is located directly above the deviation correction groove. The distance from the center of the rotating shaft to the cutting edge of the cutter is the same as the distance from the center of the rotating shaft to the inner bottom surface of the deviation correction groove.
[0006] Preferably, a blanking mechanism is arranged between the receiving conveyor belt and the deviation correction groove. The blanking mechanism includes a first conveyor belt perpendicular to the receiving conveyor belt and a second conveyor belt parallel to and above the first conveyor belt. The belt surface of the first conveyor belt is flush with the deviation correction groove. The second conveyor belt is distributed in a staggered manner with the first conveyor belt. A wire pushing mechanism for pushing the wire towards the blanking mechanism is arranged between the blanking mechanism and the deviation correction groove.
[0007] Preferably, the wire pushing mechanism includes a turntable, a swing arm, an L-shaped push rod and a connecting rod. The turntable is rotatably arranged on the side surface of the fixing plate and is driven by a motor. One end of the swing arm is rotatably connected to an eccentric position on the turntable surface through a pin shaft. The swing arm is arranged in a downward inclined manner. The vertical part of the L-shaped push rod is fixed upwards at the end of the swing arm. One end of the connecting rod is rotatably connected to the middle position of the swing arm through a pin shaft. The other end of the connecting rod is rotatably connected to the side surface of the fixing plate through a pin shaft. The swing arm and the connecting rod form a y-shape.
[0008] Preferably, a support plate is arranged above one end of the receiving conveyor belt close to the blanking mechanism. The support plate is flush with the deviation correction groove.
[0009] The beneficial effects of the present utility model are as follows: By arranging a rotary cutter above the deviation correction groove, and the distance from the rotation center of the cutter to the cutting edge is the same as the distance from the rotation center to the inner bottom surface of the deviation correction groove. When the cutter rotates downwards, it just cuts off the wire. When the cutting edge of the cutter contacts the wire, the cutter is still rotating, so it can move along with the wire and cut off the wire during the wire conveying process, without stopping the wire guiding pulley for cutting, thus greatly improving the cutting efficiency.

Detailed Embodiment
[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0017] Refer to Figure 1, An efficient wire cutting device, including a cutting table and a fixing plate 1 vertically arranged on the cutting table. On the front of the fixing plate 1, there are two traction wheels 2 for guiding the wire up and down. The traction wheels 2 are driven by a traction motor. On one side of the two traction wheels 2, there is a deviation correction groove 3 with a U-shaped cross-section. On one side of the deviation correction groove 3, there is a receiving conveyor belt 4. Above the deviation correction groove 3 on the fixing plate 1, there is a rotating shaft 5 perpendicular to the plate surface. The rotating shaft 5 is driven by a servo motor. A cutting knife 6 perpendicular to it is fixed on the rotating shaft 5. The cutting knife 6 is located directly above the deviation correction groove 3. The distance from the center of the rotating shaft 5 to the cutting edge of the cutting knife 6 is the same as the distance from the center of the rotating shaft 5 to the inner bottom surface of the deviation correction groove 3. The traction wheels 2 are used to traction the wire to be cut. The wire passes through the deviation correction groove 3 and falls on the receiving conveyor belt 4 for continuous conveying. When cutting is required, the servo motor drives the cutting knife 6 to rotate clockwise. The cutting edge of the cutting knife 6 rotates into the deviation correction groove 3 and presses and cuts off the wire. The linear velocity of the cutting edge of the cutting knife 6 is the same as the traction speed of the wire. At the moment of cutting, the cutting edge and the wire are moving synchronously. Therefore, there is no need to stop the traction wheels 2, and the wire can be cut during the traction conveying process, greatly improving the work efficiency. After cutting, the cutting knife 6 rotates upward for the next cutting.
[0018] There is a blanking mechanism between the receiving conveyor belt 4 and the deviation correction groove 3. The blanking mechanism includes a first conveyor belt 7 perpendicular to the receiving conveyor belt 4 and a second conveyor belt 8 parallel to and above the first conveyor belt 7. The belt surface of the first conveyor belt 7 is flush with the deviation correction groove 3. The second conveyor belt 8 is distributed in a staggered manner with the first conveyor belt 7. There is a wire pushing mechanism between the blanking mechanism and the deviation correction groove 3 for pushing the wire towards the blanking mechanism. The wire is placed on the upper end surface of the first conveyor belt 7. One end of the second conveyor belt 8 is located on the right side of the wire. After the wire is cut, the wire pushing mechanism pushes one end of the wire into the space between the first conveyor belt 7 and the second conveyor belt 8. The first conveyor belt 7 and the second conveyor belt 8 clamp one end of the wire and output it to the outside, thereby pulling the wire off the receiving conveyor belt 4 and falling into a material box arranged on one side of the receiving conveyor belt 4.
[0019] The wire pushing mechanism includes a turntable 9, a swing arm 10, an L-shaped push rod 11 and a connecting rod 12. The turntable 9 is rotatably arranged on the side of the fixed plate 1 and driven by a motor. One end of the swing arm 10 is rotatably connected to an eccentric position on the disk surface of the turntable 9 through a pin shaft. The swing arm 10 is arranged obliquely downward. The vertical part of the L-shaped push rod 11 is fixed upward at the end of the swing arm 10. One end of the connecting rod 12 is rotatably connected to the middle position of the swing arm 10 through a pin shaft, and the other end of the connecting rod 12 is rotatably connected to the side of the fixed plate 1 through a pin shaft. The swing arm 10 and the connecting rod 12 form a Y shape. In the initial state, one end of the swing arm 10 is at the lowest point. At this time, the L-shaped push rod 11 is located below and to the left of the wire. The motor drives the turntable 9 to rotate, thereby driving the swing arm 10 to swing. During this process, the swing arm 10 first swings upward and to the left. The swing arm 10 pulls the connecting rod to rotate clockwise, and then pulls the end of the swing arm 10 with the L-shaped push rod 11 to rise, so that the L-shaped push rod 11 moves to the upper left of the wire. At this time, the end of the swing arm 10 connected to the turntable 9 moves to the highest point. The turntable continues to rotate, and then drives the swing arm 10 to swing downward and to the right. The connecting rod 12 is pulled to rotate counterclockwise, so that the L-shaped push rod 11 moves downward and to the right, and then the vertical part of the L-shaped push rod 11 pushes one end of the wire between the first conveyor belt 7 and the second conveyor belt 8.
[0020] Above one end of the receiving conveyor belt 4 close to the blanking mechanism, there is a support plate 13. The support plate 13 is flush with the deviation correction groove 3. The support plate 13 lifts one end of the wire, reducing the length of the wire falling on the receiving conveyor belt 4, so as to facilitate the blanking mechanism to pull down the wire and drop it into the material box arranged on one side of the receiving conveyor belt 4.
[0021] The working process of the embodiment of the present application is as follows: The traction wheel 2 is used to traction the wire to be cut. The wire passes through the deviation correction groove 3 and falls on the receiving conveyor belt 4 for continuous conveying. When cutting is required, the servo motor drives the cutter 6 to rotate clockwise. The cutting edge of the cutter 6 turns into the deviation correction groove 3 and presses and cuts the wire. The linear velocity of the cutting edge of the cutter 6 is the same as the traction speed of the wire. At the moment of cutting, the cutting edge and the wire are moving synchronously. Therefore, there is no need to stop the traction wheel 2, and the wire can be cut during the traction and conveying process, greatly improving the working efficiency. After cutting, the cutter 6 rotates upward for the next cutting.
[0022] Specific embodiments are applied in the present utility model to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model; at the same time, for those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present utility model.
