Description

Technical Field

[0001] This utility model relates to the field of aluminum foil processing technology, and in particular to a feeding device for an aluminum foil slitting machine. Background Technology

[0002] Aluminum foil is a composite material made by bonding aluminum foil backing paper and aluminum foil together. Its core component, aluminum foil, is a hot stamping material made by directly rolling metallic aluminum into thin sheets. Aluminum foil combines the excellent properties of aluminum with the convenience of paper, making it an indispensable material in modern packaging and industrial fields. In the aluminum foil processing industry, the slitting machine is a key piece of equipment, and the performance of its feeding device directly affects product quality.

[0003] Chinese Patent No. CN217534856U discloses an automatic aluminum foil feeding device, including a first mounting plate, a second mounting plate, a drive roller assembly, a steering roller, and a feeding roller assembly. The drive roller assembly, steering roller, and feeding roller assembly are horizontally arranged between the two mounting plates, and the steering roller is arranged between the drive roller assembly and the feeding roller assembly. The feeding roller assembly includes a first feeding roller, a second feeding roller, a first fixed block, a second fixed block, a first rotary motor, a second rotary motor, and a vertical drive assembly. The first feeding roller is located directly above the second feeding roller. The first fixed block is located at one end of the first and second feeding rollers near the first mounting plate, and the second fixed block is located at one end of the first and second feeding rollers near the second mounting plate. The two rotary motors are located inside the two fixed blocks. The vertical drive assembly is fixedly connected to the first and second fixed blocks. This device can adjust the feeding height to ensure balance and compression during the aluminum foil feeding process.

[0004] However, the above technical solution has the following shortcomings: Although the device can press the aluminum foil by lifting the second feeding roller in conjunction with the first feeding roller, the adjustment space between the first feeding roller and the second feeding roller is very limited, which results in a very limited range of adjustment of the foil paper force. At the same time, the device cannot limit the side of the foil paper when feeding, which can easily affect the quality of subsequent slitting and winding. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a feeding device for an aluminum foil slitting machine. This device can not only expand the range of its function in adjusting the tightness of aluminum foil, but also limit and guide the side of the tin foil during feeding, thereby improving the slitting quality.

[0006] The present invention provides a feeding device for an aluminum foil slitting machine, comprising a base and a pressure regulating device. The base has a first support frame and a second support frame, with two guide rollers rotatably connected to the first and second support frames.

[0008] Preferably, the threaded block is provided with two telescopic sleeves, and the other end of the telescopic sleeve is provided on the first support frame.

[0009] Preferably, the inner ring surface of the limiting ring is provided with a first anti-slip layer, and the inner arc surface of the pressure plate is provided with a second anti-slip layer.

[0010] Preferably, a support frame is provided on the base, and a material roller is rotatably connected to the support frame.

[0011] Preferably, a mounting frame is provided on the base, a support roller is rotatably connected to the mounting frame, and a smoothing roller is provided above the support roller.

[0021] Example 1

[0022] like Figure 1 - Figure 4 As shown, the aluminum foil slitting machine feeding device proposed in this embodiment includes a base 1 and a pressure regulating device; a first support frame 2 and a second support frame 3 are provided on the base 1, and two guide rollers 21 are rotatably connected on the first support frame 2 and the second support frame 3.

[0023] The pressure regulating device includes a lifting seat 7, a pressure regulating roller 10 rotatably connected to the lifting seat 7, a drive mechanism set on the first support frame 2 and the second support frame 3, and a limiting mechanism set on the pressure regulating roller 10; the limiting mechanism includes a limiting ring 11 sleeved on the pressure regulating roller 10, a fixing plate 13 set on the limiting ring 11, a screw 14 threadedly connected to the fixing plate 13, two guide rods 16 slidably connected to the fixing plate 13, a pressure plate 17 set on the guide rods 16, a rotating connector 19 set on the pressure plate 17, a knob 15 set on the screw 14, and two nuts 20 threadedly connected to the screw 14; the end of the screw 14 away from the knob 15 is inserted into the interior of the rotating connector 19 and rotatably connected.

[0024] The drive mechanism includes a motor 4 mounted on the first support frame 2, a threaded rod 5 vertically rotatably connected to the first support frame 2, a threaded block 6 and a slider 8 mounted on the lifting seat 7, and a column 9 mounted on the second support frame 3; the motor 4 and the threaded rod 5 are threadedly connected, the threaded block 6 is threadedly connected to the threaded rod 5, and the slider 8 is slidably connected to the column 9.

[0025] In this embodiment, before feeding the aluminum foil, the distance between the limiting rings 11 can be adjusted according to the width of the aluminum foil to ensure the stability of the aluminum foil during the conveying process. During adjustment, the limiting rings 11 are first moved axially along the pressure roller 10 to the selected position. Then, the screw 14 is rotated via the knob 15, and the screw 14 engages with the fixed plate 13. Simultaneously, one end of the screw 14, inserted into the rotating connector 19, rotates. Under the guidance of the guide rod 16, the screw 14 drives the pressure plate 1... 7. Move the platen 17 until it is pressed tightly against the roller surface of the pressure roller 10. Finally, rotate the two nuts 20 to clamp the two sides of the fixing plate 13, thereby ensuring the stability of the platen 17. The operation is simple and convenient. When feeding, the motor 4 can drive the threaded rod 5 to rotate. The threaded rod 5 engages with the threaded block 6. Under the guidance of the slider 8 and the column 9, the threaded block 6 will drive the pressure roller 10 to move vertically to adjust the tension of the aluminum foil. The adjustment range is large and it has good practicality.

[0026] It should be noted that the lifting seat 7 is equipped with a pressure sensor (not shown) to detect the tension of the tin foil in real time. The sensor and an external controller transmit and process the detected information so that as the thickness of the tin foil roll decreases during the feeding process, the motor 4 drives the threaded rod 5 to rotate to adjust the height of the pressure roller 10 in real time to ensure stable tension.

[0027] Example 2

[0028] like Figure 2 and Figure 3 As shown in the figure, the aluminum foil paper slitting machine feeding device proposed in this embodiment has two telescopic sleeves 24 on the threaded block 6 compared with the first embodiment. The other end of the telescopic sleeve 24 is set on the first support frame 2. The inner ring surface of the limiting ring 11 is provided with a first anti-slip layer 12, and the inner arc surface of the pressure plate 17 is provided with a second anti-slip layer 18.

[0029] In this embodiment, the telescopic sleeve 24 is used to protect the threaded rod 5 and extend the maintenance cycle of the threaded rod 5. The first anti-slip layer 12 and the second anti-slip layer 18 are used to increase the friction between the limiting ring 11 and the pressure plate 17 and the pressure adjusting roller 10, thereby improving the stability of the limiting ring 11.

[0030] Example 3

[0031] like Figure 1 and Figure 4 As shown in the figure, the aluminum foil paper slitting machine feeding device proposed in this embodiment has an upright frame 22 on the base 1 compared with the first embodiment. The upright frame 22 is rotatably connected to the material roller 23.

[0032] A mounting frame 25 is provided on the base 1. A support roller 26 is rotatably connected to the mounting frame 25. A smoothing roller 27 is provided above the support roller 26. A vertically distributed cylinder 28 is provided on the mounting frame 25. A connecting frame 29 is driven by the cylinder 28. The smoothing roller 27 is rotatably connected to the connecting frame 29. Two guide blocks 30 are provided on the connecting frame 29. A sliding groove is provided on the mounting frame 25 for the guide blocks 30 to slide vertically.

[0033] In this embodiment, the feed roller 23 is used to wrap the aluminum foil roll. During feeding, the aluminum foil first wraps around the bottom of the guide roller 21 on one side, then around the top of the pressure adjusting roller 10, and then around the bottom of the guide roller 21 on the other side. Finally, it passes through the gap between the support roller 26 and the smoothing roller 27, and then passes through the slitting device and is wound up. The connecting frame 29 can be raised and lowered by the cylinder 28, thereby adjusting the height of the smoothing roller 27. This allows the distance between the support roller 26 and the smoothing roller 27 to be adjusted according to the thickness of the aluminum foil, avoiding the drawback of excessive or insufficient pressure affecting the slitting quality. The guide block 30 and the chute have a guiding and stabilizing effect.

[0034] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
