Description

Technical Field

[0001] This utility model relates to the field of aluminum foil paper production and processing technology, and in particular to an automatic aluminum foil paper force detection device. Background Technology

[0002] Aluminum foil is a paper-like material made by bonding aluminum foil backing paper and aluminum foil together. It is soft, easily deformed, and does not spring back after deformation, exhibiting high plasticity. As a high-performance material in the food packaging industry, the tension control during the slitting process of aluminum foil directly affects the quality of the finished product. Traditional tension control methods suffer from problems such as response lag and insufficient precision, necessitating a detection device capable of real-time tension monitoring.

This automatic tension detection device has the advantages of automatic alarm function, ability to calibrate the position of aluminum foil of different widths, and convenient operation.

[0004] However, the above technical solution has the following shortcomings: although the device can detect the tension of aluminum foil in real time and automatically alarm, it cannot adjust the height position of the second guide roller in real time according to the change of tension to control the stability of the tension, which reduces the practicality of the device. Utility Model Content

[0009] Preferably, two limiting guide rings are rotatably connected to the first guide roller, and an adjustment component is provided on the fixed seat.

[0010] Preferably, the adjusting assembly includes a connecting rod disposed on the limiting guide ring, a fixing plate disposed on the connecting rod and having two symmetrically distributed elongated holes, and four fixing bolts that pass through the elongated holes and are threadedly connected to the fixing seat.

[0012] Preferably, the inner ring surface of the limiting guide ring is provided with a filling ring.

[0013] Compared with the prior art, the present invention has the following beneficial technical effects:

[0014] 1.

[0021] Example 1

[0022] like Figure 1 - Figure 4 As shown in the figure, the automatic aluminum foil paper force detection device proposed in this embodiment includes a base 1 and a tension detection device; a first fixing frame 2 and a second fixing frame 3 are provided on the base 1.

[0023] The tension detection device includes a horizontally arranged lifting seat 4, a pressure sensor 7 and an annular support frame 11 arranged on the lifting seat 4, a fixed seat 8 arranged on the annular support frame 11, two connecting seats 9 respectively arranged at both ends of the fixed seat 8, a first guide roller 10 rotatably connected to the connecting seat 9, and a drive assembly for driving the lifting seat 4 to move vertically; two horizontally distributed second guide rollers 23 are rotatably connected to the first fixed frame 2 and the second fixed frame 3.

[0024] The drive assembly includes a threaded block 5 and a guide block 6 mounted on the lifting seat 4, a motor 12 mounted on the first fixed frame 2, a threaded rod 13 vertically rotatably connected to the first fixed frame 2, and a vertical rod 14 mounted on the second fixed frame 3; the motor 12 and the threaded rod 13 are driven together, the threaded block 5 is threadedly connected to the threaded rod 13, and the guide block 6 is slidably connected to the vertical rod 14.

[0025] In this embodiment, the first guide roller 10 and the second guide roller 23 are used to transport the aluminum foil. The first guide roller 10 changes the tension of the aluminum foil by altering its transport path, thus ensuring the flatness of the aluminum foil during transport. As the thickness of the aluminum foil roll changes during transport, the tension also changes continuously. The pressure sensor 7 can detect the compressive force on the first guide roller 10 in real time. This data can be observed in real time using an external controller and display. Furthermore, data analysis can be used to control the motor 12 driving the threaded rod 13. Rotation causes the threaded rod 13 to engage with the threaded block 5. Guided by the guide block 6 and the upright rod 14, the threaded block 5 drives the lifting seat 4 to move vertically along the axis of the upright rod 14, thereby maintaining the detected tension value within a stable range. This ensures the stability and flatness of the aluminum foil during conveying. Furthermore, when the data changes abnormally, an alarm is triggered and the machine is forcibly stopped, improving the practicality and safety of the tension detection device. This technology involves PLC programming control, sensors, data analysis, and other technologies, and is a mature existing technology, so it will not be described in detail.

[0026] Example 2

[0027] like Figure 1 and Figure 3 As shown, in this embodiment, an automatic aluminum foil paper force detection device is proposed. Compared with the first embodiment, in this embodiment, two telescopic protective sleeves 15 are provided on the threaded block 5, and the other side of the telescopic protective sleeves 15 is provided on the first fixed frame 2.

[0028] In this embodiment, the telescopic protective sleeve 15 provides a certain degree of protection for the threaded rod 13, extends the maintenance cycle of the threaded rod 13, and the telescopic protective sleeve 15 extends and retracts with the rise and fall of the threaded block 5 to ensure that it always provides protection.

[0029] Example 3

[0030] like Figure 1 , Figure 2 and Figure 4As shown in this embodiment, an automatic aluminum foil paper force detection device is proposed. Compared with the first embodiment, in this embodiment, two limiting guide rings 16 are rotatably connected to the first guide roller 10. The inner ring surface of the limiting guide ring 16 is provided with a filling ring 17. An adjustment component is provided on the fixed base 8. The adjustment component includes a connecting rod 18 provided on the limiting guide ring 16, a fixing plate 19 provided on the connecting rod 18 and having two symmetrically distributed elongated holes 20, and four fixing bolts 21 that penetrate the elongated holes 20 and are threaded to the fixed base 8. The fixed base 8 is provided with a plurality of linearly arrayed limiting holes 22. The fixing bolts 21 are threaded to the inside of the limiting holes 22. The length dimension of the elongated holes 20 is greater than the length distance of three adjacent limiting holes 22. The filling ring 17 is used as a buffer material between the guiding limiting ring 16 and the first guide roller 10 to avoid wear when the first guide roller 10 rotates.

[0031] In this embodiment, the limiting guide ring 16 can guide and transport the side of the aluminum foil, preventing the aluminum foil from shifting. The position of the limiting guide ring 16 can also be adjusted according to the width of the aluminum foil to expand the applicable range. When adjusting, the limiting guide ring 16 is first moved along the axial direction of the first guide roller 10 to the selected position. Then, the four fixing bolts 21 are respectively passed through the elongated hole 20 and screwed into the interior of the limiting hole 22 to fix the limiting guide ring 16.

[0032] It should be noted that the connecting seat 9 can also be equipped with a threaded fixing rod with a nut threaded on it. By adjusting the nut, the two sides of the limiting guide ring 16 can be clamped, thereby further improving the stability of the limiting guide ring 16. However, this requires more production and maintenance costs.

[0033] 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.
