Abstract

This invention belongs to the field of wire cutting technology, specifically a wire conveying and cutting device, including a base plate. A first fixed blade holder is fixedly connected to the top of the base plate, and a first blade is fixedly connected to the first fixed blade holder. Through the structural design of the third and fourth blades, when wire cutting is required, the motor is started, and the motor drives the circular plate and the semi-circular guide block to rotate. The semi-circular guide block first contacts the first fixed post, pressing the first fixed post downward. The first fixed post drives the first rotating blade holder to rotate around the pivot. The second blade cooperates with the first blade to cut the wire. When the semi-circular guide block contacts the second fixed post, the third blade also rotates around the pivot. The third and fourth blades only cut the protective sleeve of the wire and do not cut the internal conductor, which facilitates the subsequent removal of the protective sleeve. This realizes the function of cutting the protective sleeve at one end of the wire during the wire cutting process.

Description

Technical Field

[0001] This invention relates to the field of wire cutting technology, specifically a wire conveying and cutting device. Background Technology

[0002] Conductors refer to the materials used as wires and cables. In industry, they also refer to electrical wires. They are generally made of copper or aluminum, and sometimes silver wire. They are used to conduct electric current or heat. Conductors are usually wound into coils for easy handling. When handling conductors, a special cutting device is required to cut the conductors during the handling and transportation process.

[0003] Existing wire cutting devices include two cutter holders and two blades. After the wire is fed out to a certain length, pressure is applied to the two cutter holders so that the two blades cut the wire. Before subsequent use, the protective sleeve of the wire at one end of the cut wire needs to be removed with a special tool to facilitate the subsequent use of the wire.

[0004] However, current wire cutting devices cannot remove the protective sleeve at one end of the wire. Users need to use additional tools to cut the protective sleeve at one end of the wire, which is inconvenient, time-consuming and labor-intensive. Therefore, a wire conveying and cutting device is proposed to address the above problems. Summary of the Invention

The third spring is sleeved on the outside of the moving rod, and the other end of the moving rod is fixedly connected to a toothed plate. The toothed plate is arc-shaped and adapted to the wire. A first guide rod is fixedly connected to the top of the bottom plate, and a lifting plate is slidably connected to the surface of the first guide rod. A fourth spring is fixedly connected between the lifting plate and the bottom plate, and the fourth spring is sleeved on the outside of the first guide rod. Two vertical columns are fixedly connected to the bottom of the lifting plate, and the vertical columns are located directly above the arc surface of the arc-shaped plate.

[0016] The advantages of this invention are:

[0017] 1. This invention, through the structural design of the third and fourth blades, allows for the cutting of wires when a motor is started. The motor drives the circular plate and the semi-circular guide block to rotate. The semi-circular guide block first contacts the first fixed post, pressing the first fixed post downwards. The first fixed post drives the first rotating blade holder to rotate around the axis. The second blade works with the first blade to cut the wire. When the semi-circular guide block contacts the second fixed post, the third blade also rotates around the axis. The third and fourth blades only cut the protective sleeve of the wire, without cutting the inner conductor, making it convenient to remove the protective sleeve later. This invention achieves the function of cutting the protective sleeve at one end of the wire during the wire cutting process, solving the problem that current wire cutting devices cannot remove the protective sleeve at one end of the wire.

[0018] 2. Through the structural design of the toothed plate, during the rotation of the first rotating cutter holder, the second crossbar will press the L-shaped plate downward. Due to the action of the first arc-shaped block and the sixth spring, the first arc-shaped block will reach below the second arc-shaped block. During the rotation of the second rotating cutter holder, the first crossbar will press the lifting plate downward. The lifting plate will drive the two vertical columns to move downward. The vertical columns can press the arc-shaped plates on both sides to move towards the middle. The two toothed plates can tightly clamp the protective sleeve of the wire. When the semi-circular guide block is not in contact with the first fixed column, the second crossbar moves upward. Under the action of the fifth spring, the first arc-shaped block moves upward. The first arc-shaped block will drive the second arc-shaped block to rotate. The second arc-shaped block will drive the circular plate to rotate, thereby causing the toothed plate to drive the protective sleeve of the cut part to rotate, completely separating the protective sleeve from the protective sleeve behind.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-7As shown, a wire conveying and cutting device includes a base plate 1. A first fixed blade holder 2 is fixedly connected to the top of the base plate 1. A first blade 3 is fixedly connected to the first fixed blade holder 2. A first rotating blade holder 4 is rotatably connected to the first fixed blade holder 2 via a rotating shaft. A second blade 5 is fixedly connected to the first rotating blade holder 4. A first fixing plate 6 is fixedly connected to both the first fixed blade holder 2 and the first rotating blade holder 4. A first spring 7 is fixedly connected between the two first fixing plates 6. A vertical plate 8 is fixedly connected to the top of the base plate 1. A circular ring plate 9 is rotatably connected to the vertical plate 8. The middle part of the ring plate 9 is used to limit the wire. The top of the base plate 1 is fixedly connected to a second fixed knife seat 10. A third blade 11 is fixedly connected to the second fixed knife seat 10. A second rotating knife seat 12 is rotatably connected to the second fixed knife seat 10 through a rotating shaft. The angle between the second rotating knife seat 12 and the horizontal plane is greater than that of the first rotating knife seat 4. A fourth blade 13 is fixedly connected to the second rotating knife seat 12. A second fixed plate 14 is fixedly connected to both the second fixed knife seat 10 and the second rotating knife seat 12. A second spring 15 is fixedly connected between the two second fixed plates 14.

[0030] During operation, the wire to be cut is passed through the circular plate 9. When cutting is required, the motor 17 is started, driving the circular plate 18 to rotate. The circular plate 18 drives the semi-circular guide block 19 to rotate. When the ramp area 40 of the semi-circular guide block 19 first contacts the first fixed post 1901, the ramp area 40 will press the first fixed post 1901 downward. The first fixed post 1901 will drive the first rotating blade holder 4 to rotate around the pivot, compressing the first spring 7. The first rotating blade holder 4 drives the second blade 5 to rotate, and the second blade 5, in conjunction with the first blade 3, cuts the wire. When the ramp area 40 of the semi-circular guide block 19 contacts the second fixed post 1901, the wire is cut. When post 1902 contacts, the first fixed post 1901 contacts the horizontal area 41, and the ramp area 40 can press the second fixed post 1902 to move downward. The second fixed post 1902 drives the second rotating blade holder 12 to rotate, and the second rotating blade holder 12 drives the fourth blade 13 to rotate. The fourth blade 13, together with the third blade 11, cuts the protective sleeve at one end of the wire. Since the original angle of the second rotating blade holder 12 is greater than that of the first rotating blade holder 4, and the length of the second fixed post 1902 is less than that of the first fixed post 1901, the third blade 11 and the fourth blade 13 only cut the protective sleeve of the wire and do not cut the internal conductor.

[0031] A support plate 16 is fixedly connected to the top of the base plate 1, a motor 17 is fixedly connected to the top of the support plate 16, a circular plate 18 is fixedly connected to the output shaft of the motor 17, a semi-circular guide block 19 is fixedly connected to the bottom of the circular plate 18, a first fixed post 1901 is fixedly connected to the first rotating tool holder 4, a second fixed post 1902 is fixedly connected to the second rotating tool holder 12, the length of the first fixed post 1901 is greater than the length of the second fixed post 1902, and the top ends of the first fixed post 1901 and the second fixed post 1902 are in contact with the bottom of the circular plate 18.

[0032] During operation, since the original angle of the second rotating cutter holder 12 is greater than that of the first rotating cutter holder 4, and the length of the second fixed post 1902 is less than that of the first fixed post 1901, the third blade 11 and the fourth blade 13 only cut the protective sleeve of the wire and do not cut the internal conductor.

[0033] Two third fixing plates 20 are fixedly connected to the vertical plate 8. A moving rod 21 is slidably inserted into the third fixing plate 20. An arc-shaped plate 22 is fixedly connected to one end of the moving rod 21. A third spring 23 is fixedly connected between the arc-shaped plate 22 and the third fixing plate 20. The third spring 23 is sleeved on the outside of the moving rod 21. A toothed plate 24 is fixedly connected to the other end of the moving rod 21. The toothed plate 24 is arc-shaped and adapted to the wire. A first guide rod 25 is fixedly connected to the top of the bottom plate 1. A lifting plate 26 is slidably connected to the surface of the first guide rod 25. A fourth spring 27 is fixedly connected between the lifting plate 26 and the bottom plate 1. The fourth spring 27 is sleeved on the outside of the first guide rod 25. Two vertical columns 28 are fixedly connected to the bottom of the lifting plate 26. The vertical columns 28 are located directly above the arc surface of the arc-shaped plate 22. A first horizontal bar 29 is fixedly connected to the second rotating tool holder 12. The first horizontal bar 29 is in contact with the top of the lifting plate 26.

[0034] A second guide rod 30 is fixedly connected to the top of the base plate 1. An L-shaped plate 31 is slidably connected to the surface of the second guide rod 30. A fifth spring 32 is fixedly connected between the L-shaped plate 31 and the base plate 1. The fifth spring 32 is sleeved on the outside of the second guide rod 30. A moving column 33 is slidably inserted on the L-shaped plate 31. A square plate 34 is fixedly connected to the moving column 33. A sixth spring 35 is fixedly connected between the square plate 34 and the L-shaped plate 31. The sixth spring 35 is sleeved on the outside of the moving column 33. A first arc-shaped block 36 is fixedly connected to one end of the moving column 33. A fixing block 37 is fixedly connected to the annular plate 9. A second arc-shaped block 38 is fixedly connected to one end of the fixing block 37. The arc surface of the second arc-shaped block 38 is located directly below the arc surface of the first arc-shaped block 36. A second crossbar 39 is fixedly connected to the first rotating tool holder 4. The second crossbar 39 is in contact with the top of the L-shaped plate 31.

[0035] During operation, after cutting the wire, the first rotating blade holder 4 can also drive the second crossbar 39 to rotate. The second crossbar 39 can press the L-shaped plate 31 to move downward, compressing the fifth spring 32. The fifth spring 32 is a hard spring with high elasticity. The L-shaped plate 31 drives the first arc block 36 to move downward. When the first arc block 36 contacts the second arc block 38, the first arc block 36 moves towards the L-shaped plate 31, compressing the sixth spring 35. When the first arc block 36 and the second arc block 38 are no longer in contact, under the action of the sixth spring 35, the first arc block 36 returns to its original position, and the first arc block 36 is located below the second arc block 38. The second rotating blade holder 12 can also drive the first crossbar 29 to rotate. The first crossbar 29 can press the lifting plate 26 to move downward, compressing the fourth spring 27. 6 drives the two vertical columns 28 to move downwards. The two vertical columns 28 can press the arc plates 22 on both sides to move towards the middle. The arc plates 22 drive the two toothed plates 24 to move towards the middle through the moving rod 21. The two toothed plates 24 can tightly clamp the cut protective sleeve. When the semi-circular guide block 19 is not in contact with the first fixed column 1901 and the second fixed column 1902 is in contact with the horizontal area 41, under the action of the first spring 7, the first rotating knife holder 4 returns to the initial position. Under the action of the fifth spring 32, the L-shaped plate 31 moves upwards. The L-shaped plate 31 drives the first arc block 36 to move upwards. The first arc block 36 will drive the second arc block 38 to rotate. The second arc block 38 drives the circular plate 9 to rotate. The circular plate 9 drives the cut protective sleeve to rotate through the toothed plate 24, so that the cut protective sleeve is completely broken from the protective sleeve behind it.

[0036] The semi-circular guide block 19 is provided with two ramp areas 40 and a horizontal area 41. The two ramp areas 40 are located on both sides of the horizontal area 41. The ramp areas 40 are used to press the first fixed column 1901 and the second fixed column 1902.

[0037] During operation, the ramp area 40 of the semi-circular guide block 19 can compress the first fixed post 1901 and the second fixed post 1902 to rotate downwards, while the horizontal area 41 can keep the first fixed post 1901 and the second fixed post 1902 in the cutting state.

[0038] The third fixing plate 20 has a first circular hole 42, and the moving rod 21 slides through the first circular hole 42.

[0039] During operation, as the arc plate 22 and the toothed plate 24 move, the moving rod 21 slides within the first circular hole 42, limiting the arc plate 22 and the toothed plate 24 in the horizontal direction.

[0040] The lifting plate 26 has a second circular hole 43, and the first guide rod 25 passes through the second circular hole 43.

[0041] During operation, as the lifting plate 26 moves, the first guide rod 25 slides within the second circular hole 43, limiting the lifting plate 26 to the vertical direction.

[0042] The L-shaped plate 31 has a third circular hole 44, and the second guide rod 30 passes through the third circular hole 44.

[0043] During operation, as the L-shaped plate 31 moves, the second guide rod 30 slides within the third circular hole 44, limiting the L-shaped plate 31 in the vertical direction.

[0044] The L-shaped plate 31 has a rectangular opening 45, and the movable column 33 slides through the rectangular opening 45.

[0045] During operation, as the first arc-shaped block 36 moves, the moving column 33 slides within the rectangular opening 45, limiting the first arc-shaped block 36 in the vertical direction.

[0046] A stop block 46 is fixedly connected to the annular plate 9, and a fixing block 37 rests on the top of the stop block 46. A counterweight block 47 is fixedly connected to the outer wall of the annular plate 9, and the counterweight block 47 faces directly downward.

[0047] During operation, the counterweight 47 keeps the annular plate 9 in this state, and the stop block 46 prevents the second arc-shaped block 38 from rotating downward.

[0048] Working principle: In use, the wire to be cut is passed through the circular plate 9. When the wire needs to be cut, the motor 17 is started. The motor 17 drives the circular plate 18 to rotate, and the circular plate 18 drives the semi-circular guide block 19 to rotate. When the ramp area 40 of the semi-circular guide block 19 first contacts the first fixed post 1901, the ramp area 40 will press the first fixed post 1901 to move downward. The first fixed post 1901 will drive the first rotating blade holder 4 to rotate around the pivot, and the first spring 7 will be compressed. The first rotating blade holder 4 drives the second blade 5 to rotate. The second blade 5, together with the first blade 3, cuts the wire. The first rotating blade holder 4 can also drive the second crossbar 39 to rotate. The second crossbar 39 can press the L-shaped plate 31 to move downward, and the fifth spring 32 will be compressed. Spring 32 is a hard spring with high elasticity. The L-shaped plate 31 drives the first arc-shaped block 36 downwards. When the first arc-shaped block 36 contacts the second arc-shaped block 38, it moves towards the L-shaped plate 31, compressing the sixth spring 35. When the first arc-shaped block 36 and the second arc-shaped block 38 are no longer in contact, under the action of the sixth spring 35, the first arc-shaped block 36 returns to its original position, positioned below the second arc-shaped block 38. When the ramp area 40 of the semi-circular guide block 19 contacts the second fixed post 1902, the first fixed post 1901 contacts the horizontal area 41. The ramp area 40 can compress the second fixed post 1902 downwards, causing it to rotate. The second fixed post 1902 drives the second rotating tool holder 12 to rotate. The blade holder 12 drives the fourth blade 13 to rotate. The fourth blade 13, in conjunction with the third blade 11, cuts the protective sleeve at one end of the wire. Because the original angle of the second rotating blade holder 12 is greater than that of the first rotating blade holder 4, and the length of the second fixed post 1902 is less than that of the first fixed post 1901, the third blade 11 and the fourth blade 13 only cut the protective sleeve of the wire without cutting the internal conductor. The second rotating blade holder 12 can also drive the first crossbar 29 to rotate. The first crossbar 29 can press the lifting plate 26 to move downward, compressing the fourth spring 27. The lifting plate 26 drives the two vertical posts 28 to move downward, and the two vertical posts 28 can press the arc plates 22 on both sides to move towards the middle. The arc plates 22, through the moving rod 21, drive the two toothed plates 24 to move towards the middle. During the intermediate movement, the two toothed plates 24 can tightly clamp the cut protective sleeve. When the semi-circular guide block 19 is not in contact with the first fixed post 1901, and the second fixed post 1902 is in contact with the horizontal area 41, under the action of the first spring 7, the first rotating cutter holder 4 returns to its initial position. Under the action of the fifth spring 32, the L-shaped plate 31 moves upward, driving the first arc-shaped block 36 to move upward. The first arc-shaped block 36 drives the second arc-shaped block 38 to rotate, and the second arc-shaped block 38 drives the circular plate 9 to rotate. The circular plate 9, through the toothed plates 24, drives the cut protective sleeve to rotate, causing the cut protective sleeve to completely break away from the protective sleeve behind it. The semi-circular guide block 19 continues to rotate, and after the second fixed post 1902 is no longer in contact with the semi-circular guide block 19...Under the action of the second spring 15, the second rotating cutter holder 12 returns to its initial position. Under the action of the fourth spring 27, the lifting plate 26 and the vertical column 28 return to their initial positions, completing the cutting of the wire and the cutting of the protective sleeve at one end of the wire.
