Description

Technical Field

[0001] This utility model relates to the field of terminal block manufacturing technology, and in particular to a continuous copper rod feeding device. Background Technology

[0002] Before production, the copper rod needs to be divided into short copper rods, which are then processed into terminal blocks by stamping and other methods.

[0003] In existing technologies, straight long copper bars are usually cut into short copper bars in a machine. Since the length of the long copper bars can be transported during the transportation process, new long copper bars need to be added after the long copper bars are processed into short copper bars. This process not only requires operators to complete, but also wastes processing time each time a new long copper bar is added, which seriously restricts the production efficiency of short copper bars.

[0023] Please see Figure 1-7 This utility model provides a continuous copper rod feeding device, comprising: A copper rod unwinding device 1 includes a base 11 and an unwinding drum 12 rotatably mounted on the base; A copper rod conveying device includes a support box 2 and a conveying frame 3 rotatably disposed within the support box. The conveying frame 3 includes two parallel side plates 33 and a first end plate 31 and a second end plate 32 for connecting the two ends of the two side plates 33 in the length direction, respectively. A first through hole 311 is provided on the first end plate 31, and a second through hole 321 is provided on the second end plate 32. The axes of the first through hole 311 and the second through hole 321 coincide. A plurality of transmission frames 4 are provided on the opposite surfaces of the two side plates 33. The plurality of transmission frames 4 are arranged along the length direction of the side plates 33, and transmission rollers 41 are provided on the transmission frames 4. Copper rod cutting device 5, used to cut long copper rods into short copper rods; The copper rod coil is placed on the unwinding drum 12. The end of the copper rod coil passes through the first perforation 311, between the two side plates 33, and the second perforation 321 in sequence. The copper rod cutting device 5 cuts the long copper rod into short copper rods. The conveying frame 3 rotates around the axis of the first perforation 311, driving several transmission frames 4 to roll around the outer surface of the long copper rod. When the several transmission frames 4 act on the outer side wall of the long copper rod, they straighten the long copper rod and push it towards the direction of the second perforation 321.

[0024] The copper rod unwinding device 1 in this application is used to place copper rod coils, which are formed by bending and winding relatively long copper rods. Compared with long copper rods, copper rod coils can be longer, allowing for the processing of more short copper rods at once. Compared with long copper rods, it saves time in adding long copper rods, thus saving time in replacing them. The end of the long copper rod enters the conveyor frame 3, which rotates around the axis of the first through hole 311. During the rotation of the conveyor frame 3, the transmission roller 41 rotates, and the transmission roller 41 rolls in the circumferential direction of the long copper rod, gradually straightening the bent long copper rod. At the same time, when the transmission roller 41 acts on the outer surface of the long copper rod, it can push the long copper rod towards the second end plate 32, thereby causing the long copper rod to continuously move towards the copper rod cutting device 5. Then, the copper rod cutting device 5 cuts the long copper rod into short copper rods.

[0025] In this embodiment, as Figure 3 As shown, the two ends of the two side plates 33 in the length direction are fixedly connected to the first end plate 31 and the second end plate 32 by welding, forming a rectangular conveyor frame 3.

[0026] In this embodiment, four transmission frames 4 are provided on each of the two side plates 33. The four transmission frames 4 are staggered.

[0027] In one embodiment, such as Figure 4As shown, the transmission frame 4 includes a support base 42; two support plates 43 are arranged parallel to each other on one side of the support base 42 in the thickness direction, and the two ends of the transmission roller 41 are respectively rotatably mounted on the two support plates 43.

[0028] In this embodiment, the support plate 43 is fixedly connected to the support base 42 by welding. The shafts at both ends of the drive roller 41 are rotatably mounted on the two support plates 43, allowing the drive roller 41 to rotate freely on the support base 42.

[0029] An adjusting screw 44 is rotatably provided on the other side of the support base 42 in the thickness direction. The side plate 33 is provided with a side plate through hole 331 that is threadedly engaged with the adjusting screw 44. The adjusting screw 44 passes through the side plate through hole 331 and is rotatably connected to the support base 42.

[0030] In this embodiment, the adjusting screw 44 and the support plate 43 are respectively disposed at both ends of the support base 42 along its length. The adjusting screw 44 is used to adjust the distance between the support base 42 and the side plate 33. Specifically, in order to enable the transmission roller 41 to better act on the surface of the long copper rod, it is necessary to adjust the distance between the transmission roller 41 and the side plate 33. When it is necessary to adjust the position of the transmission roller 41, the adjusting screw 44 can be rotated, and the end of the adjusting screw 44 is rotatably connected to the support base 42, so that the support base 42 is adjusted to a suitable position, and then the adjusting screw 44 can be stopped.

[0031] In a further embodiment, such as Figure 4 As shown, a locking nut 441 is also threaded onto the adjusting screw 44.

[0032] When the adjusting screw 44 is rotated to the appropriate position, the locking nut 441 is rotated so that the locking nut 441 abuts against the side plate 33, thereby locking the adjusting screw 44.

[0033] In a further embodiment, locking screws 45 are threaded to both ends of the support base 42 along its length; support holes 421 are provided through both ends of the support base 42 along its length, and the locking screws 45 are threadedly engaged with the support holes 421. The locking screw 45 abuts against the side plate 33 to lock the support base 42.

[0034] To further lock the support base 42, locking screws 45 are threaded to both ends of the support base 42 along its length. When the support base 42 is adjusted to the appropriate position, first rotate the locking nut 441 to lock the adjusting screw 44. Then rotate the locking screw 45 so that the end of the locking screw 45 abuts against the side plate 33, thereby locking the support base 42 at both ends.

[0035] In a further embodiment, such as Figure 4 As shown, the outer wall of the transmission roller 41 is concave inward, so that after the transmission roller 41 is cut along its axial direction, the outer wall of the transmission roller 41 is a symmetrically arranged concave shape.

[0036] In this embodiment, the outer wall of the transmission roller 41 contracts inward, so that when the conveyor frame 3 rotates, the copper rod can always be on the outer wall of the transmission roller 41. In other words, the concave transmission roller 41 can limit the long copper rod, ensuring that the long copper rod can be located on the inner wall of the transmission roller 41, and further ensuring that the long copper rod can be straightened smoothly.

[0037] In one embodiment, such as Figure 2 and Figure 5 As shown, a first rotating bushing 34 is rotatably provided on the side of the first end plate 31 away from the second end plate 32, and the first rotating bushing 34 corresponds to the first through hole 311; a second rotating bushing 35 is provided on the side of the second end plate 32 away from the first end plate 31, and the second rotating bushing 35 corresponds to the second through hole 321. A transmission wheel 36 is fixedly provided on the periphery of the first rotating shaft sleeve 34; The bottom of the support box 2 is provided with a motor 6, and the output end of the motor 6 is provided with an output wheel 61. The output wheel 61 and the transmission wheel 36 are driven by a belt 62.

[0038] The first rotating bushing 34 and the second rotating bushing 35 are both rotatably mounted on the support box 2.

[0039] In this embodiment, the first rotating shaft sleeve 34 and the second rotating shaft sleeve 35 are mounted on the side wall of the support box 2. The first rotating shaft sleeve 34 and the second rotating shaft sleeve 35 can rotate relative to the support box 2. The motor 6 drives the transmission wheel 36 to rotate via the belt 62. The transmission wheel 36 drives the first rotating shaft sleeve 34 to rotate, allowing the conveyor frame 3 to rotate around the axis of the first through hole 311. The first rotating shaft sleeve 34 and the second rotating shaft sleeve 35 are hollow, allowing the long copper rod to pass sequentially through the first rotating shaft sleeve 34, the first through hole 311, between the two side plates 33, the second through hole 321, and the second rotating shaft sleeve 35 before entering the copper rod cutting device 5.

[0040] In a further embodiment, the support box 2 includes a box body 21 and a box cover 22 rotatably disposed on the box body 21; The transmission frame 4 is installed inside the housing 21.

[0041] In this embodiment, the support box 2 is configured as a box body 21 and a box cover 22. By opening the box cover 22, it is convenient to repair and maintain the parts inside the box body 21.

[0042] In a further embodiment, such as Figure 6 and Figure 7 As shown, the copper rod cutting device 5 includes a cutting frame 51 and a cutting cylinder 52 disposed on the top of the cutting frame 51. The output end of the cutting cylinder 52 passes through the top of the cutting frame 51 and is connected to an upper cutter 53. The cutting frame 51 is provided with a lower cutting blade 54 that cooperates with the upper cutting blade 53; After the long copper rod passes through the second perforation 321, it enters between the upper cutter 53 and the lower cutter 54. The cutting cylinder 52 drives the upper cutter 53 to move closer to the lower cutter 54, cutting the long copper rod into short copper rods.

[0043] In this embodiment, the cutting cylinder 52 is a hydraulic cylinder. The hydraulic cylinder 52 drives the upper cutter 53 to move, so that the upper cutter 53 and the lower cutter 54 can cooperate with each other to cut the long copper rod into short copper rods.

[0044] In addition, the cutting frame 51 is provided with sliding grooves 511 on both sides, and the upper cutter 53 slides along the sliding grooves 511 on both sides.

[0045] The upper cutter 53 can slide along the groove 511, so that when the upper cutter 53 approaches the lower cutter 54, it can guide the lower cutter 54.

[0046] In a further embodiment, a feeding trough plate 55 is also installed on the cutting frame 51. The feeding trough plate 55 is inclined, and trough plate pivots 551 are provided on both sides of the feeding trough plate 55. The trough plate pivots 551 are rotatably mounted on the cutting frame 51. The end of the feeding trough plate 55 near the cutting frame 51 is higher than the upper surface of the lower cutter 54, so that when the lower cutter 54 drives the long copper rod to move downward, the long copper rod can push the feeding trough plate 55 to rotate around the trough plate pivot 551.

[0047] After the lower cutter 54 cuts the long copper rod, the short copper rod falls into the feeding trough 55. Then, when the upper cutter 53 moves upward, the side of the trough 551 away from the lower cutter 54 has a larger weight, causing the feeding trough 55 to reset under its own gravity. This process repeats, keeping the feeding trough 55 in a reciprocating rotating state, allowing the short copper rod to slide along the feeding trough 55 and fall smoothly into the collection box, where the cut short shaft is collected and awaits further processing.

[0048] The copper rod continuous feeding device provided in this embodiment is used in which the copper rod is placed on the unwinding drum 12, and the end of the copper rod passes through the first rotating sleeve 34, the first through hole 311, between the two side plates 33, the second through hole 321 and the second rotating sleeve 35 in sequence, and enters the cutting device 5.

[0049] Motor 6 drives transmission wheel 36 via belt 62, which in turn drives first rotating shaft sleeve 34 and the entire conveyor frame 3 to rotate around the axis of first through hole 311. Multiple transmission rollers 41 on the conveyor frame 3 roll along the outer circumference of the copper rod, applying a corrective force to straighten the bent copper rod, while simultaneously pushing the copper rod toward the cutting device 5 through rolling friction.

[0050] Rotating the adjusting screw 44 can change the distance between the support base 42 and the side plate 33, thereby adjusting the pressure of the transmission roller 41 on the copper rod; after adjustment, tighten the locking nut 441 and the locking screw 45 to fix the position of the support base 42.

[0051] After passing through the second perforation 321, the copper rod enters the space between the upper cutter 53 and the lower cutter 54. The cutting cylinder 52 drives the upper cutter 53 to move downward along the slide groove 511, cooperating with the lower cutter 54 to cut the copper rod and form a short copper rod of a specified length.

[0052] The feeding trough plate 55 is installed at an angle and can rotate around the trough plate pivot 551. The cut short copper rods fall onto the feeding trough plate 55; when the upper cutter 53 retracts, the feeding trough plate 55 resets under the action of gravity, causing it to vibrate, so that the short copper rods slide along the trough plate into the collection box.

[0053] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
