Description

Technical Field

[0001] The invention relates to the field of copper strip processing, in particular to a streamlined copper strip cutting frame. Background Art

[0002] In the electronics, electrical, communications and other industries, copper strip is a key conductive material. Its processing quality directly affects the performance of the end product, making the processing accuracy requirements of copper strip increasingly stringent. Among them, cutting is one of the core processes of copper strip processing.

[0003] Currently, traditional copper strip cutting equipment generally suffers from low automation and lagging production efficiency. After the copper strip is cut, it mostly relies on manual collection. Operators need to frequently manually move the cut copper strip segments and arrange them neatly. The cut copper strips are prone to problems such as stacking and disorder, making subsequent unloading and packaging very troublesome and time-consuming. Workers need to repeatedly move and organize the copper strips for a long time, which is time-consuming and labor-intensive. This also directly leads to relatively low efficiency in subsequent packaging. It cannot be seamlessly connected with modern production lines and is difficult to meet the needs of enterprises for intelligent and flexible production transformation.

[0011] Compared with the related art, the streamlined copper strip cutting frame provided by the present invention has the following beneficial effects:

[0012] The present invention drives the horizontal shaft to rotate through the output end of a small motor, and the sprocket on the horizontal shaft cooperates with the chain to make the synchronous shaft drive the auxiliary roller to rotate synchronously, so that the copper strip material can then fall smoothly onto the supporting plate in the storage shell. The secondary gear at one end of the horizontal shaft meshes with the main gear to rotate the adjusting shaft, driving the supporting plate to slowly move downward along the vertical rod and the open slot. The slowly falling supporting plate cooperates with the storage shell to automatically complete the storage and collection of the sequentially accumulated copper strips, so that the copper strip segments can be automatically compacted and stacked, so as to facilitate subsequent further storage and packaging processing.

[0013] The present invention drives the adjustment shaft to rotate through the output end of the side motor, and the side rack threadedly connected to the adjustment shaft slides along the two limit rods.

One end of the right-angle matching shell is close to the top tightening plate, and the right-angle matching shell and the guide rail plate can form a moving channel, which is convenient for the subsequent movement of the neatly arranged copper strip segments for storage and boxing.

[0014] The present invention activates the electric push rod on the convex plate, so that the push block at the telescopic end thereof extends through the through-hole in the right-angle matching shell, pushing the neatly arranged copper belt segments to move through the guide rail plate. One end of the copper belt segment approaches the top tightening plate, so that the top tightening plate drives the two slide bars to slide relative to the end plate surface of the guide rail plate. Both springs undergo elastic deformation, so that the neatly arranged copper belt segments can be directly shifted to the top of the through-drop groove, thereby completing the position alignment of the arranged copper belt segments and the through-drop groove.

[0015] The present invention drives the double-headed shaft to rotate through the output end of the auxiliary motor. Since the threads at both ends of the double-headed shaft are in opposite directions, the transverse blocks connected to the threads at both ends respectively drive the bottom inclined blocks to move in opposite directions along the guide rods. Since the matching rack on the bottom inclined block is engaged with the driving gear, the two driving gears drive the two connecting shafts to rotate, and the two unfolding and retracting plates rotate around the two connecting shafts respectively, so that the two unfolding and retracting plates are automatically rotated and opened, and the neatly arranged copper belt segments can directly fall smoothly from the through-drop chute, so that the fallen copper belt segments can fall into the packaging boxes transported in sequence on the conveyor belt, thereby automatically completing the boxing processing of the copper belt segments.

The two pins 6 are both rotatably connected to the lower end wall of the storage shell 4, and one end of the pin 6 is fixedly connected to the side gear Wheel 61, a side rack 62 is provided at the lower side of the side gear 61, the side rack 62 and the side gear 61 are meshed with each other, a fixing bar 63 is fixedly connected to the outer wall of the base 1, two limit rods 64 are fixedly connected to the fixing bar 63, the side rack 62 is slidably connected to the two limit rods 64, and an adjusting shaft 65 is rotatably connected to the fixing bar 63.

The adjusting shaft 65 is a threaded rod, and a back seat is provided on the rear side of the side rack 62, which is threadedly connected to the adjusting shaft 65.

[0028] In the specific implementation process, Figure 2 and Figure 5 As shown, the adjustment shaft 45 is a threaded rod, and a threaded opening is provided on the convex plate on the other side. The convex plate on the other side is threadedly connected to the adjustment shaft 45. A staggered notch is provided at the middle position of the supporting plate 42, and the staggered notch is aligned with the lower end of the right-angle matching shell 41.

[0029] It should be noted that: the adjusting shaft 45 rotates, so that the convex plate threadedly connected to the adjusting shaft 45 drives the supporting plate 42 to slowly move downward along the vertical rod 43 and the opening groove. The slowly falling supporting plate 42 cooperates with the storage shell 4 to automatically complete the storage and collection of the copper strips stacked in sequence, so as to facilitate subsequent further storage and packaging processing;

[0030] The offset notch in the middle of the supporting plate 42 is aligned with the lower end of the right-angle matching shell 41, so that when the supporting plate 42 falls to the bottom position, the copper strip segments can be automatically compacted and stacked.

[0031] The output end of the small motor 54 drives the horizontal shaft 51 to rotate, and the sprocket 53 on the horizontal shaft 51 drives the synchronous shaft 46 to rotate via the chain 55, so that the synchronous shaft 46 drives the auxiliary roller 31 to rotate synchronously, so that the copper strip material can fall smoothly onto the support plate 42 in the storage shell 4;

[0032] The output end of the side motor 66 drives the adjustment shaft 65 (threaded rod) to rotate, and the side rack 62 threadedly connected to the adjustment shaft 65 slides stably along the two limit rods 64. The side rack 62 meshes with the side gear 61, so that the side gear 61 can drive the pin 6 to rotate;

[0033] The rotation of the pin shaft 6 can drive the right-angle mating shell 41 to rotate and tilt relative to the storage shell 4 until it lies flat. One end of the right-angle mating shell 41 is close to the top tightening plate 72. The right-angle mating shell 41 and the guide plate 71 can form a moving channel, which is convenient for the subsequent storage and packing of the neatly arranged copper strip segments.

[0034] refer to Figure 4 and Figure 5 As shown, the main gear 5 and the sub-gear 52 are both bevel gears, and the main gear 5 and the sub-gear 52 are meshed with each other.

[0035] It should be noted that the secondary gear 52 at one end of the horizontal shaft 51 is engaged with the main gear 5 , so that the rotation of the horizontal shaft 51 can synchronously drive the adjustment shaft 45 to rotate.

[0036] refer to Figure 1 and Figure 7 As shown, the lower end of the base 1 is fixedly connected to a bottom support plate 7, one end of the bottom support plate 7 is fixedly connected to a boss 67, an electric push rod 68 is installed and connected to the boss 67, and a push block is provided at the telescopic end of the electric push rod 68. A through opening is provided at the lower end of the right-angle matching shell 41, and a guide rail plate 71 is fixedly connected to the bottom support plate 7, one end of the guide rail plate 71 is aligned with the lower end of the storage shell 4, and a tightening plate 72 is provided inside the guide rail plate 71. Two sliding rods 73 are symmetrically fixedly connected to some of the plate surfaces of the tightening plate 72, and the two sliding rods 73 are slidably connected to the other end plate surface of the guide rail plate 71. Springs 74 are sleeved and connected to the two sliding rods 73, and the other ends of the two sliding rods 73 are commonly connected to a back plate 75.

[0037] It should be noted that: the electric push rod 68 on the protruding seat 67 is activated, so that the push block at its telescopic end extends through the through-hole in the right-angle matching shell 41, pushing the neatly arranged copper strip segments to move through the guide plate 71, thereby adjusting the packing position of the neatly arranged copper strip segments;

[0038] One end of the copper strip segment is close to the tightening plate 72, so that the tightening plate 72 drives the two slide bars 73 to slide relative to one end plate surface of the guide rail plate 71, and the two springs 74 are elastically deformed. The tightening plate 72 can assist the neatly arranged copper strip segments to move to the top of the through-drop groove 76, thereby completing the position alignment of the copper strip segments.

[0039] refer to Figure 7 and Figure 8 As shown, a through slot 76 is provided at the other end of the bottom support plate 7, and two expansion and retraction plates 77 are symmetrically provided in the through slot 76. A connecting shaft 78 is fixedly connected to the two expansion and retraction plates 77, and the two connecting shafts 78 are rotatably connected to the slot wall of the through slot 76.

[0040] It should be noted that: the rotation of the two connecting shafts 78 drives the two unfolding and retracting plates 77 to rotate around the two connecting shafts 78 respectively, so that the two unfolding and retracting plates 77 can automatically rotate and open, and the neatly arranged copper belt segments can fall smoothly from the through-drop groove 76, so that the fallen copper belt segments can fall into the packaging boxes transported in sequence on the conveyor belt, thereby automatically completing the packing processing of the copper belt segments.

[0041] refer to Figure 8 and Figure 9 As shown, one end of the two connecting shafts 78 is fixedly connected to the driving gear 8, and a bottom oblique block 81 is provided at the lower position of the two driving gears 8. The side walls of the two bottom oblique blocks 81 are fixedly connected to the matching racks 82, and the two matching racks 82 are meshed with the two driving gears 8. A mounting frame 83 is fixedly connected to the side wall of the bottom support plate 7, and a guide rod 84 is fixedly connected to the mounting frame 83. Both ends of the guide rod 84 are slidably connected to a transverse block 85. The two transverse blocks 85 are respectively fixedly connected to the two bottom oblique blocks 81, and a double-headed shaft 86 is rotatably connected to the mounting frame 83. One end of the mounting frame 83 is installed and connected to an auxiliary motor 87. The output end of the auxiliary motor 87 is fixedly connected to one end of the double-headed shaft 86. The two ends of the double-headed shaft 86 are symmetrically provided with threads in opposite directions. The two transverse blocks 85 are provided with threaded openings, and the two transverse blocks 85 are respectively threadedly connected to the two ends of the double-headed shaft 86.

[0042] It should be noted that: the output end of the auxiliary motor 87 drives the double-headed shaft 86 to rotate. Since the threads at both ends of the double-headed shaft 86 are in opposite directions, the transverse blocks 85 connected to the threads at both ends respectively drive the bottom bevel block 81 to move in the opposite direction along the guide rod 84. Since the matching rack 82 on the bottom bevel block 81 is engaged with the drive gear 8, the two drive gears 8 can automatically drive the two connecting shafts 78 to rotate.

[0043] The streamlined copper strip cutting stand provided by the present invention operates as follows: The copper strip is conveyed by auxiliary conveyor rollers 11, moved to the bottom of the cutting assembly 2, and slitting is completed. The cut copper strip slides down the front chute 3. A small motor 54 is activated, and its output end drives the horizontal shaft 51 to rotate. The sprocket 53 on the horizontal shaft 51 drives the synchronous shaft 46 via the chain 55, which in turn drives the auxiliary rollers 31 to rotate synchronously, allowing the copper strip to smoothly fall onto the support plate 42 in the storage housing 4.

[0044] The secondary gear 52 at one end of the horizontal shaft 51 is engaged with the main gear 5, causing the adjusting shaft 45 to rotate (the adjusting shaft 45 is a threaded rod), and the convex plate threadedly connected to the adjusting shaft 45 drives the supporting plate 42 to move slowly downward along the vertical rod 43 and the open groove. The slowly falling supporting plate 42 cooperates with the storage shell 4 to automatically complete the storage and collection of the copper strips stacked in sequence, so as to facilitate subsequent further storage and packaging processing.

[0045] When the supporting plate 42 falls to the bottom, the offset notch in the middle of the supporting plate 42 is aligned with the lower end of the right-angle matching shell 41, so that the copper strip segments can be automatically compacted and stacked.

[0046] Start the side motor 66 so that its output end drives the adjusting shaft 65 (threaded rod) to rotate, and the side rack 62 threadedly connected to the adjusting shaft 65 slides along the two limit rods 64. The side rack 62 engages with the side gear 61, so that the side gear 61 can drive the pin shaft 6 to rotate, and then drive the right-angle matching shell 41 to rotate and tilt relative to the storage shell 4 until it lies flat. One end of the right-angle matching shell 41 is close to the tightening plate 72. The right-angle matching shell 41 is combined with the guide plate 71 to form a moving channel, which is convenient for the subsequent storage and packing of the neatly arranged copper strip segments.

[0047] Start the electric push rod 68 on the protrusion 67, so that the push block at its telescopic end extends through the through-hole in the right-angle matching shell 41, pushing the neatly arranged copper belt segment to move through the guide plate 71. One end of the copper belt segment is close to the tightening plate 72, so that the tightening plate 72 drives the two slide bars 73 to slide relative to one end plate surface of the guide plate 71. Both springs 74 undergo elastic deformation, so that the neatly arranged copper belt segment can move to the top of the through-groove 76, completing the position alignment of the copper belt segment.

[0048] The auxiliary motor 87 is started, and its output end drives the double-headed shaft 86 to rotate. Since the threads at both ends of the double-headed shaft 86 are in opposite directions, the transverse blocks 85 connected to the threads at both ends respectively drive the bottom inclined block 81 to move in the opposite directions along the guide rod 84. Since the matching rack 82 on the bottom inclined block 81 is engaged with the driving gear 8, the two driving gears 8 drive the two connecting shafts 78 to rotate, and the two unfolding and retracting plates 77 rotate around the two connecting shafts 78 respectively, so that the two unfolding and retracting plates 77 automatically rotate and open, and the neatly arranged copper belt segments can fall smoothly from the through-drop groove 76, so that the fallen copper belt segments can fall into the packaging boxes transported in sequence on the conveyor belt, thereby automatically completing the packing processing of the copper belt segments.
