The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] Please refer to Figure 1 to Figure 4 The embodiment of the utility model provides an electric bicycle aluminum alloy label forming device, comprising:

[0039] A workbench 1, on the top of which a bracket 11 is fixedly arranged;

[0040] A lifting unwinding mechanism 2 is arranged at one end of the workbench 1 and is used for unwinding the aluminum alloy coil 8;

[0041] A lifting and winding mechanism 3 is arranged at the other end of the workbench 1 and is used for winding the aluminum alloy coil 8;

[0042] The forming mechanism 4 is arranged on the workbench 1 and the bracket 11. The forming mechanism 4 includes a forming cylinder 41 arranged on the bracket 11. The telescopic end of the forming cylinder 41 is vertically downward and fixedly provided with an upper mounting plate 42. An upper template 43 is fixedly provided on the bottom surface of the upper mounting plate 42. The bottom surface of the upper template 43 is evenly distributed with mold knives 44. A lower mounting plate 45 is arranged below the upper template 43. The top surface of the workbench 1 is symmetrically provided with baffles 46 on both sides of the lower mounting plate 45. The two sides of the lower mounting plate 45 are respectively slidably connected with the baffles 46 on the same side. A lifting cylinder 47 for driving the lower mounting plate 45 to move up and down is arranged in the workbench 1. A lower template 48 is fixedly provided on the top surface of the lower mounting plate 45. The top surface of the lower template 48 is provided with an avoidance gap 49 adapted to the mold knives 44.

[0043] The unloading mechanism 5 is arranged on the bracket 11 and is located on one side between the two baffles 46;

[0044] The material collecting mechanism 6 is arranged on a side of the workbench 1 away from the material unloading mechanism 6;

[0045] The controller 7 is fixedly arranged on one side of the bracket 11 and is electrically connected to the lifting unwinding mechanism 2, the lifting rewinding mechanism 3, the forming mechanism 4 and the unloading mechanism 5 respectively.

[0046] In this embodiment, when processing the aluminum alloy label, the aluminum alloy coil 8 is placed on the lifting and unwinding mechanism 2, and one end of the aluminum alloy coil 8 passes through the upper template 43 and the lower template 48 and is fixed on the lifting and reeling mechanism 3; at this time, the forming cylinder 41 drives the upper template 43 to press down, and the mold knife 44 cuts the aluminum alloy coil 8 and inserts it into the avoidance gap 49, and then the forming cylinder 41 drives the upper template 43 to rise, and the aluminum alloy label is retained on the top surface of the lower template 48; the lower mounting plate 45 is driven downward by the lifting cylinder 47 to leave enough space between the lower template 48 and the bottom surface of the aluminum alloy coil 8; then the unloading mechanism 5 pushes the aluminum alloy label from one end to the other between the two baffles 46, so that it falls into the collecting mechanism 6 for collection, and the automatic unloading and collection are completed. During the unloading process, the lifting and reeling mechanism 3 drives the aluminum alloy coil 8 to move forward a certain distance. After the unloading mechanism 5 and the lower template 48 are reset, the cutting and forming of the aluminum alloy label continues, realizing the automated production of the aluminum alloy label, with good operation continuity and high production efficiency, and is suitable for the mass production of aluminum alloy labels.

[0047] In a preferred embodiment, if Figure 1 As shown, the top surface of the workbench 1 is located between the bracket 11 and the lifting unwinding mechanism 2 and between the bracket 11 and the lifting rewinding mechanism 3, and a first distance sensor 12 is respectively provided; the top surface of the workbench 1 is located below the lower mounting plate 45 and a second distance sensor 13 is provided; the first distance sensor 12 and the second distance sensor 13 are both electrically connected to the controller 7.

[0048] In this embodiment, the height of the aluminum alloy coil 8 on both sides of the forming mechanism 4 is monitored by the first distance sensor 12, and then the height of the aluminum alloy coil 8 is adjusted by the lifting unwinding mechanism 2 and the lifting rewinding mechanism 3, so that the aluminum alloy coil 8 passing through the forming mechanism 4 is kept horizontal, ensuring the forming quality of the aluminum alloy label. The height of the lower mounting plate 45 is monitored by the second distance sensor 13, so that the lower template 48 can meet the position requirements for cutting and unloading the aluminum alloy label after lifting and moving.

[0049] In a preferred embodiment, if Figure 1 As shown, the lifting and unwinding mechanism 2 includes two vertically arranged first frames 21, each of which is provided with a first slide groove 22 in the vertical direction, a lead screw 23 is provided in the first slide groove 22 in the vertical direction, a first driving motor 24 for driving the lead screw 23 to rotate is provided on the top of the first frame 21, a first lifting plate 25 is threadedly sleeved on the lead screw 23, the first lifting plate 25 is slidably connected to the first slide groove 22, a first mounting block is fixedly provided on the inner side of the first lifting plate 25, a damping roller 26 is installed between the two first mounting blocks, and an aluminum alloy coil 8 is wound around the damping roller 26.

[0050] In this embodiment, as the outer diameter of the aluminum alloy coil 8 is unwound, it gradually decreases, and the first drive motor 24 drives the lead screw 23 to rotate and drive the first lifting plate 25 to rise along the first slide groove 22, so that the height of the output aluminum alloy coil 8 is moderate and consistent, ensuring that the aluminum alloy coil 8 passing through the forming mechanism 4 remains horizontal, thereby ensuring the forming quality of the aluminum alloy label.

[0051] In a preferred embodiment, if Figure 1 As shown, the lifting and winding mechanism 3 includes two vertically arranged second frames 31, and second slide grooves 32 are opened on the two second frames 31 along the vertical direction. A second lifting plate 33 is slidably connected in the second slide grooves 32, and a driving cylinder 36 for driving the second lifting plate 33 to move up and down is arranged in the second slide grooves 32. A second mounting block is fixedly arranged on the inner side of the second lifting plate 33, and a winding roller 35 is installed between the two second mounting blocks. A second driving motor 36 for driving the winding roller 35 to rotate is arranged on the outer side of any second lifting plate 33.

[0052] In this embodiment, the winding roller 35 is driven by the second driving motor 36 to rotate and wind up the aluminum alloy coil 8 after cutting. As the winding progresses, the outer diameter of the aluminum alloy coil 8 on the winding roller 35 gradually increases, and the second lifting plate 33 is driven by the driving cylinder 36 to descend along the second slide groove 32, so that the height of the aluminum alloy coil 8 at the input end of the winding roller 35 is moderate and consistent, ensuring that the aluminum alloy coil 8 passing through the forming mechanism 4 remains horizontal, thereby ensuring the forming quality of the aluminum alloy label.

[0053] In a preferred embodiment, if Figure 3and Figure 4 As shown, the top surface of the lower template 48 is symmetrically provided with positioning holes 410 on both sides of the aluminum alloy coil 8, and the bottom surface of the upper template 43 is provided with positioning pins 411 corresponding to the positioning holes 410. The outer diameter of the bottom end of the positioning pin 411 gradually decreases from top to bottom to form a guide head 412.

[0054] In this embodiment, before the upper mold 43 and the lower mold 48 are molded together, the positioning pins 411 are respectively inserted into the corresponding positioning holes 410 under the guidance of the guide head 412 to accurately position the upper mold 43 and the lower mold 48, thereby ensuring accurate mold closing.

[0055] In a preferred embodiment, if Figure 3 and Figure 4 As shown, there are multiple groups of upper templates 43 and lower templates 48, and each group of upper templates 43 is provided with mold knives 44 of different structures; the upper templates 43 are detachably fixedly mounted on the bottom surface of the upper mounting plate 42 by screws, and the lower templates 48 are detachably fixedly mounted on the top surface of the lower mounting plate 45 by screws.

[0056] In this embodiment, the cutter 44 is a closed cutter whose blade is formed in the shape of the aluminum alloy label, so that the aluminum alloy label is cut and shaped directly on the aluminum alloy coil 8. The cutter 44 can be rectangular, circular, oval, diamond or other irregular shapes. By replacing the upper template 43 and the lower template 48, the production requirements of aluminum alloy labels of different shapes can be met, and the adaptability is good.

[0057] In a preferred embodiment, if Figure 3 As shown, the bottom surface of the upper mold plate 43 is located inside the mold knife 44 and is fixedly provided with an elastic rubber column 413 .

[0058] In this embodiment, the height of the elastic rubber column 413 is slightly greater than the depth of the mold knife 44. When the upper template 43 moves downward, the elastic rubber column 413 first presses the portion of the aluminum alloy coil 8 within the cutting range, thereby ensuring the stability of the cutting. After the cutting is completed, the aluminum alloy label is ejected from the mold knife 44 under the elastic action of the elastic rubber column 413, thereby preventing the aluminum alloy label from being stuck in the mold knife 44. The structural design is reasonable and the practicability is good.

[0059] In a preferred embodiment, if Figure 2 As shown, the unloading mechanism 5 includes a rubber push plate 51 disposed outside between the two baffles 46 , and a unloading cylinder 52 for driving the rubber push plate 51 to extend into and out of between the two baffles 45 is fixedly disposed on the bracket 11 .

[0060] In this embodiment, after the aluminum alloy label is cut, the lifting cylinder 47 drives the lower template 48 to descend, so that the top surface of the lower template 48 is at the same height as the bottom surface of the rubber push plate 51. At this time, the unloading cylinder 52 extends to drive the rubber push plate 51 to extend between the two baffles 45, and pushes the aluminum alloy label from the top surface of the lower template 48 to complete the automatic unloading. The rubber push plate 51 can prevent the aluminum alloy label from being damaged during the unloading process, ensuring the yield rate.

[0061] In a preferred embodiment, if Figure 1 and Figure 2 As shown, the material collection mechanism 6 includes a material discharge chute 61 and a material collection box 62; the material discharge chute 61 is embedded in one side of the workbench 1, its top end extends to the side of the two baffles 46 away from the material discharge mechanism 5, and its bottom end extends to the outside of the workbench 1; the material collection box 62 is arranged below the bottom end of the material discharge chute 61.

[0062] In this embodiment, the top end of the discharge chute 61 is located below the end of the lower template 48 away from the discharge mechanism 5, ensuring that all the aluminum alloy labels pushed down by the discharge mechanism 5 are collected. The aluminum alloy labels slide down the discharge chute 61 by gravity and fall into the collection box 62 below, realizing the automatic collection of the aluminum alloy labels.

[0063] In a preferred embodiment, if Figure 1 As shown, a forklift slot 63 is provided at the bottom of the collection box 62, so as to facilitate the use of a forklift to carry the collection box 62 filled with aluminum alloy labels.
