Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum foil product manufacturing equipment, in particular to an aluminum foil stamping oiling feeder. Background Art
[0002] When producing aluminum foil and paper containers, the raw materials are too thin (0.04-0.20mm) and the surface is bright and smooth. If the tension is too large or too small during production, it is very easy to be pulled off, wrinkled, or broken. In addition, the raw materials of aluminum foil or paper containers are provided to manufacturers in batches in rolls. During production, the rolls are loaded on the feeding machine and pulled out by pressing. At this time, it is necessary to ensure that the pulled aluminum foil or paper is taut and the surface is flat, but not too tight (exceeding the material tensile force range of 90-140Mpa, the material will tear), nor too loose (too loose will cause the material surface to wrinkle).
[0003] At present, the unwinding roller is used to carry the rolled raw materials. The unwinding roller is driven by a motor. In order to meet the tension requirements of the aluminum foil on the surface of the product, the motor controls the unwinding roller to rotate within a preset time period to release the aluminum foil of a preset length. The motor stops to control the unwinding roller to stop rotating and unwinding. When the released aluminum foil is used to make products, the motor starts to rewind. However, since the unwinding roller and the rolled raw materials on it have a large mass, the unwinding roller continues to rotate and unwind under the action of inertia, resulting in the final unwinding length exceeding the preset length. The aluminum foil segment released first is prone to shaking during the processing process. Therefore, the aluminum foil is prone to wrinkles during subsequent unwinding, which seriously affects the product quality. Utility Model Content
[0004] The utility model aims to provide an aluminum foil stamping oiling feeder, aiming to solve the technical problem that the aluminum foil is prone to wrinkles during the unwinding process in the prior art.

[0027] The aluminum foil stamping oiling feeder proposed in the utility model comprises: a frame 1; an unwinding mechanism, which is arranged on the frame 1, and comprises an unwinding roller 2 and a magnetic powder brake 3, wherein the unwinding roller 2 is rotatably arranged on the frame 1, and one end of the unwinding roller 2 is drivingly connected to the driving end of the magnetic powder brake 3; an oil immersion tank 4, which is arranged on the frame 1, and along the unwinding direction of the unwinding roller 2, the oil immersion tank 4 is arranged at intervals on one side of the unwinding mechanism, and the oil immersion tank 4 has an inner cavity opening toward the top (not marked in the figure), and an oil immersion roller 5 is arranged in the inner cavity; a traction mechanism, which is arranged on the frame 1, and the traction mechanism is used to traction the aluminum foil 100 released by the unwinding mechanism; and a tensioning roller 6, which is rotatably connected to the frame 1, and the tensioning roller 6 is provided with a tension sensor 7, and the tension sensor 7 is used to detect the tensioning force of the aluminum foil 100 passing through the surface of the tensioning roller 6. Please refer to Figure 1 and Figure 2 .
[0028] The present application discloses an unwinding mechanism including an unwinding roller 2 and a magnetic powder brake 3; and a tensioning roller 6, wherein the tensioning roller 6 is rotatably connected to the frame 1, and the tensioning roller 6 is provided with a tension sensor 7, and the tension sensor 7 is used to detect the tension of the aluminum foil 100 passing through the surface of the tensioning roller 6. In practical applications, the magnetic powder brake 3 has the following characteristics: when the excitation current remains unchanged, the torque it transmits is not affected by the differential speed (slip speed) between the transmission member and the driven member, that is, there is no difference between the static torque and the dynamic torque. Therefore, a constant torque can be stably transmitted. If this characteristic is applied to tension control, the user only needs to adjust the magnitude of the excitation current to accurately control and transmit the required torque, thereby achieving the purpose of controlling the tension of the coil simply and effectively. It can be seen from the above content that when the magnetic powder brake 3 is used in combination with the tension sensor 7 in the present application, the magnetic powder brake 3 drives the unwinding roller 2 to unwind at a uniform speed based on the real-time detection value of the tension sensor 7, thereby avoiding the release of excess aluminum foil 100 due to stage shutdown under the inertial rotation of the structure, reducing or preventing the problem of wrinkles on the surface of the aluminum foil 100 during the unwinding process, and significantly improving the product quality of the aluminum foil product.
[0029] For details, please refer to Figure 1 and Figure 2 The traction mechanism tractions the aluminum foil 100 released from the unwinding roller 2. In this process, the movement path of the aluminum foil 100 is: the unwinding roller 2, the tensioning roller 6, the oil-immersing roller 5 and the traction mechanism. When the aluminum foil 100 passes through the oil-immersing roller 5, the aluminum foil 100 is immersed below the liquid level of the oil in the oil-immersing tank 4.
[0030] See also Figure 2 In this embodiment, along the unwinding direction, the tensioning roller 6 is located between the unwinding mechanism and the traction mechanism, and the tensioning roller 6 is located above the oil immersion tank 4.
[0031] The aluminum foil 100 is first tensioned by the tension roller 6 and then sent out. This type of structural setting facilitates real-time detection of the tension of the aluminum foil 100 without affecting the data accuracy by the intermediate structure or process. The aluminum foil 100 is tensioned by the tension roller 6 and then moves downward to the oil immersion tank 4 to immerse in oil. This type of structural setting moves from top to bottom, and the aluminum foil 100 is close to the surface of the tension roller 6, which can increase the effectiveness of the tension sensor 7 in detecting the tension value.
[0032] See also Figure 2 In this embodiment, the frame 1 is further provided with a guide roller 8, and along the unwinding direction, the guide roller 8 is located between the tensioning roller 6 and the unwinding mechanism. Figure 2 In this embodiment, there are two guide rollers 8 , one of which has a higher level than the tensioning roller 6 , and the other guide roller 8 has a lower level than the tensioning roller 6 .
[0033] The movement path of the aluminum foil 100 is: unwinding roller 2, guide roller 8 (upper), guide roller 8 (lower), tensioning roller 6, oil-immersed roller 5 and traction mechanism. This type of structural setting, adding two upper and lower guide rollers 8, can guide the movement of the aluminum foil 100 and increase its movement stability.
[0034] See also Figure 2 In this embodiment, the traction mechanism is located above the oil immersion tank 4.
[0035] This type of structural arrangement allows the aluminum foil 100 to move upward within a preset movement path, so that excess oil on the surface of the aluminum foil 100 is separated from the surface of the aluminum foil 100 under the action of gravity.
[0036] To increase traction efficiency, refer to Figures 1 to 3In this embodiment, the traction mechanism includes a motor 9 and a plurality of traction rollers 10. The motor 9 is arranged on the frame 1. The plurality of traction rollers 10 are arranged on the frame 1 at intervals in the height direction. Gears 11 are provided at the ends of the traction rollers 10. The gears 11 at the ends of two adjacent traction rollers 10 are meshed and connected, and one of the traction rollers 10 is driven and connected to the driving end of the motor 9.
[0037] like Figure 2 As shown, there are three traction rollers 10. After the aluminum foil 100 comes out of the oil immersion tank 4, it goes around the surfaces of the lowest traction roller 10 and the middle traction roller 10 in turn. When the surfaces of the two adjacent traction rollers 10 are in close contact to achieve the traction effect on the aluminum foil 100, the aluminum foil 100 is stably pulled and sent out of the frame 1.
[0038] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
