Technical Field

[0001] The utility model relates to the field of metal can processing, in particular to an automatic flanging structure for metal can processing. Background Technique

[0002] Metal cans are widely used packaging containers, which are usually made of metals such as aluminum, iron, steel or tin. Metal cans have good corrosion resistance, protection, recyclability, durability and diversification. When metal cans are produced and processed, since the edges of the metals are relatively sharp, the openings of the metal cans will be flanged.

[0003] The main purpose of flanging the metal can is to enhance the structural strength of the can body, improve the sealing performance and improve the appearance. By flanging the metal can, the edge part of the metal can can be better supported, thereby enhancing its compressive and impact resistance.

[0004] After the existing metal cans are flanged, manual blanking is generally required, and the metal cans are manually taken out from the device, which easily affects the efficiency of the entire metal can flanging processing work.

[0005] Therefore, it is necessary to provide a new automatic flanging structure for metal can processing to solve the above technical problems. Content of the Utility Model

[0006] To solve the above technical problems, the utility model provides an automatic flanging structure for metal can processing.

[0007] The automatic flanging structure for metal can processing provided by the utility model includes a workbench, a load-bearing frame is fixedly connected to the top of the workbench, a turntable is rotatably connected to the top of the workbench, an electric push rod is fixedly connected to the inner top wall of the load-bearing frame, the bottom end of the electric push rod is fixedly connected to a mounting frame, and flanging frames are slidably connected to both ends of the bottom of the mounting frame. A fixed frame is fixedly connected to one side of the mounting frame, and a rack is fixedly connected to the side of the fixed frame close to the load-bearing frame.

A winding rod is rotatably connected to one side of the limiting frame, and one end of the winding rod is fixedly connected to one end of the gear rotating shaft.

[0009] An installation plate is fixedly connected to one side of the top of the workbench. A spring is fixedly connected to the side of the installation plate close to the turntable. A limiting plate is fixedly connected to the end of the spring close to the turntable. A traction rope is fixedly connected to the side of the limiting plate close to the installation plate, and the other end of the traction rope is fixedly connected to the winding rod.

[0010] Preferably, rotating rods are rotatably connected to both sides of the limiting plate. The mounting plate is provided with mounting holes, and the traction rope is located in the mounting holes. A pulley is rotatably connected to the side of the mounting plate away from the spring through a frame body, and the traction rope is placed on the pulley.

[0011] Preferably, a chute is provided at the top of the turntable. A bidirectional lead screw is rotatably connected in the chute, and the thread grooves at both ends of the bidirectional lead screw are opposite. Clamping plates are threadedly connected to both ends of the bidirectional lead screw.

[0012] Preferably, the mounting frame is provided with limiting holes, and knob Bs are threadedly connected to the flanging frames through the limiting holes.

[0016] 1. After the flanging work is completed in the present utility model, the electric push rod drives the mounting frame to rise. At this time, the fixed frame drives the rack to rise. During the rising process of the rack, it can cooperate with the gear to drive the winding rod to rotate. The winding rod releases the traction rope. At this time, the limit on the spring disappears, and it starts to rebound, driving the limiting plate to push the metal can located on the turntable to complete the blanking work. This enables the device to automatically complete the blanking work of the metal can after the flanging work is completed, further improving the working efficiency of the device for flanging and processing metal cans.

[0017] 2. When the present utility model is performing flanging work on the metal can, the traction rope can pull the limiting plate to move, so that the rotating rods on both sides of the limiting plate are attached to the metal can.

Detailed implementation manners

[0025] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] The following describes in detail the specific implementation of the present utility model with reference to specific embodiments.

[0027] Please refer to Figures 1 to 6 , an automatic flanging structure for metal can processing provided by an embodiment of the present utility model includes a workbench 1. A load-bearing frame 11 is fixedly connected to the top of the workbench 1. Support legs 12 are fixedly connected to the four corners of the bottom of the workbench 1, and gaskets are fixedly connected to the bottom ends of the support legs 12.

[0028] It should be noted that: The workbench 1 and the load-bearing frame 11 are the load-bearing main bodies of the device. The workbench 1 can improve its stability after placement through the support legs 12 at the four corners of the bottom, and the load-bearing frame 11 can be used for installing the electric push rod 3 and its connecting components.

[0029] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 and Figure 6, a turntable 2 is rotatably connected to the top of the workbench 1. A chute 21 is provided on the top of the turntable 2. A bidirectional lead screw 22 is rotatably connected in the chute 21, and the thread grooves at both ends of the bidirectional lead screw 22 are opposite. Clamping plates 23 are threadedly connected to both ends of the bidirectional lead screw 22. One side of the turntable 2 is rotatably connected to a knob A 24, and the knob A 24 is fixedly docked with one end of the bidirectional lead screw 22. The bottom of the workbench 1 is fixedly connected to a motor 25, and the output end of the motor 25 is fixedly docked with the bottom of the turntable 2.

[0030] It should be noted that: when flanging the metal can, rotate the knob A 24 to drive the bidirectional lead screw 22 to rotate. Since the thread grooves at both ends of the bidirectional lead screw 22 are opposite, during the rotation of the bidirectional lead screw 22, the clamping plates 23 at both ends can be separated. At this time, place the metal can on the turntable 2, and then rotate the knob A 24 in the reverse direction. At this time, the reversely rotating bidirectional lead screw 22 can drive the clamping plates 23 at both ends to close. When the clamping plates 23 are attached to the metal can, stop rotating the knob A 24. At this time, the two clamping plates 23 can be used to clamp and fix the metal can. Then start the motor 25 to drive the turntable 2 to rotate. The turntable 2 can drive the metal can to rotate. By cooperating the rotating metal can with the flanging frame 32, the flanging work can be carried out on the metal edge of the opening of the metal can.

[0031] In the embodiment of the present invention, please refer to Figure 1 , Figure 2 and Figure 3 , a power-driven push rod 3 is fixedly connected to the inner top wall of the load-bearing frame 11. The bottom end of the power-driven push rod 3 is fixedly connected to a mounting frame 31, and both ends of the bottom of the mounting frame 31 are slidably connected to a flanging frame 32. A fixing frame 35 is fixedly connected to one side of the mounting frame 31, and a rack 36 is fixedly connected to the side of the fixing frame 35 close to the load-bearing frame 11. A limiting hole 33 is provided on the mounting frame 31, and a knob B 34 is threadedly connected to the flanging frame 32 through the limiting hole 33.

[0032] It should be noted that: when flanging the metal can, rotate the knob B 34 to eliminate the limiting effect on the flanging frame 32. At this time, move the flanging frame 32 along the mounting frame 31, align the groove in the flanging frame 32 with the edge of the opening of the metal can, and then rotate the knob B 34 in the reverse direction to limit and fix the flanging frame 32. Then start the power-driven push rod 3 to drive the mounting frame 31 to descend. At this time, during the descent of the mounting frame 31, the flanging frame 32 can be driven to be stuck on the edge of the metal can. As the power-driven push rod 3 continues to press down, the groove on the flanging frame 32 is used to cooperate with the rotating metal can to complete the flanging work on the metal can. At the same time, during the descent of the mounting frame 31, the rack 36 can be driven to move through the fixing frame 35. At this time, the rack 36 can drive the gear 41 to rotate to complete the transmission work on the winding rod 42.

[0033] In an embodiment of the present utility model, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 , on one side of the load-bearing frame 11 close to the fixed frame 35, a limiting frame 4 is fixedly connected. A gear 41 that meshes with the rack 36 is rotatably connected to the limiting frame 4. One side of the limiting frame 4 is rotatably connected to a winding rod 42, and one end of the winding rod 42 is fixedly butted with one end of the rotating shaft of the gear 41. On one side of the top of the workbench 1, a mounting plate 5 is fixedly connected. A spring 51 is fixedly connected to one side of the mounting plate 5 close to the turntable 2. One end of the spring 51 close to the turntable 2 is fixedly connected to a limiting plate 52. A traction rope 56 is fixedly connected to one side of the limiting plate 52 close to the mounting plate 5, and the other end of the traction rope 56 is fixedly connected to the winding rod 42. Rotating rods 53 are rotatably connected to both sides of the limiting plate 52. Mounting holes 54 are provided on the mounting plate 5, and the traction rope 56 is located in the mounting holes 54. A pulley 55 is rotatably connected to one side of the mounting plate 5 away from the spring 51 through a frame body, and the traction rope 56 is placed on the pulley 55.

[0034] It should be noted that: during the downward movement of the mounting frame 31, the rack 36 that moves along with it can drive the gear 41 to rotate, and the gear 41 drives the winding rod 42 to rotate. During the rotation of the winding rod 42, the traction rope 56 can be wound. After the traction rope 56 is wound, it can drive the limiting plate 52 to move towards the mounting plate 5 and squeeze the spring 51 to make it contract. At this time, the rotating rods 53 at both ends of the limiting plate 52 will fit on the outer wall of the metal can, and cooperate with the clamping plate 23 to fix and limit the metal can. At the same time, since the rotating rods 53 are rotatably connected, the rotation of the metal can is not affected. When the flanging work of the metal can is completed, reverse-rotate the knob A24 to drive the bidirectional lead screw 22 to rotate, and use the bidirectional lead screw 22 to drive the clamping plates 23 at both ends thereof to separate from the metal can, releasing the limit of the metal can. At this time, control the electric push rod 3 to contract to drive the mounting frame 31 to lift, so that the flanging frame 32 is separated from the edge of the metal can. At the same time, the fixed frame 35 that rises together with the mounting frame 31 can drive the gear 41 to rotate in the reverse direction through the rack 36. At this time, the gear 41 drives the winding rod 42 to rotate in the reverse direction, and the winding rod 42 can loosen the traction rope 56 wound around it. At this time, the spring 51 starts to rebound, driving the limiting plate 52 to apply pressure to the metal can, and using the limiting plate 52 to push the metal can off the turntable 2 to complete the blanking work. After that, a new metal can can be placed on the turntable 2. During the movement of the traction rope 56, the pulley 55 can reduce the friction force received by the traction rope 56 and increase the service life of the traction rope 56 to a certain extent.

[0035] The working principle of the automatic flanging structure for metal can processing provided by the present utility model is as follows:

[0036] First, install the workbench 1 at the specified position, and then power on the device to perform the flanging work on the metal can;

[0037] When performing the flanging work on the metal can, rotate the knob A24 to drive the bidirectional lead screw 22 to rotate. Since the thread grooves at both ends of the bidirectional lead screw 22 are opposite, during the rotation of the bidirectional lead screw 22, the clamping plates 23 at both ends can be separated. At this time, place the metal can on the turntable 2, and then rotate the knob A24 in the reverse direction. At this time, the reversely rotating bidirectional lead screw 22 can drive the clamping plates 23 at both ends to close. When the clamping plates 23 are attached to the metal can, stop rotating the knob A24. At this time, the two clamping plates 23 can be used to clamp and fix the metal can;

[0038] After that, rotate the knob B34 to cancel the limiting effect on the flanging frame 32. At this time, move the flanging frame 32 along the mounting frame 31, align the groove in the flanging frame 32 with the edge of the opening of the metal can, and then rotate the knob B34 in the reverse direction to limit and fix the flanging frame 32. Then start the electric push rod 3 to drive the mounting frame 31 to descend. At this time, during the descent of the mounting frame 31, it can drive the flanging frame 32 to be stuck at the edge of the metal can. As the electric push rod 3 continues to press down, during this process, start the motor 25 to drive the turntable 2 to rotate. The turntable 2 can drive the metal can to rotate. Through the cooperation of the rotating metal can and the flanging frame 32, the flanging work can be performed on the metal edge of the opening of the metal can;

[0039] During the extension of the electric push rod 3, the descending mounting frame 31 can drive the gear 41 to rotate through the moving rack 36. The gear 41 drives the winding rod 42 to rotate. During the rotation of the winding rod 42, the traction rope 56 can be wound. After the traction rope 56 is wound, it can drive the limiting plate 52 to move towards the mounting plate 5 and squeeze the spring 51 to make it contract. At this time, the rotating rods 53 at both ends of the limiting plate 52 will be attached to the outer wall of the metal can to cooperate with the clamping plates 23 to fix and limit the metal can. At the same time, since the rotating rods 53 are rotatably connected, the rotation of the metal can is not affected. When the flanging work of the metal can is completed, rotate the knob A24 in the reverse direction to drive the bidirectional lead screw 22 to rotate, and use the bidirectional lead screw 22 to drive the clamping plates 23 at both ends to separate from the metal can to release the limit of the metal can. At this time, control the electric push rod 3 to contract to drive the mounting frame 31 to lift, so that the flanging frame 32 is separated from the edge of the metal can. At the same time, the fixed frame 35 that rises together with the mounting frame 31 can drive the gear 41 to rotate in the reverse direction through the rack 36. At this time, the gear 41 drives the winding rod 42 to rotate in the reverse direction, and the winding rod 42 can loosen the traction rope 56 wound on it. At this time, the spring 51 starts to rebound, driving the limiting plate 52 to apply pressure to the metal can, and using the limiting plate 52 to push the metal can off the turntable 2 to complete the blanking work.

[0040] The circuits and controls involved in the present utility model are all prior arts, and will not be elaborated here.

[0041] The above are only embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural or equivalent process transformations made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present utility model.
