DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The core of the present invention is to provide an aluminum film static elimination device for a strip bag packaging machine, which can eliminate static electricity on the surface of the aluminum film 1.

[0033] It should be noted that the directions or positional relationships indicated by “upper”, “lower”, “front”, “back”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application.

[0034] The present application provides an aluminum film static elimination device for a strip bag packaging machine, which is arranged on an aluminum film conveying assembly for conveying an aluminum film 1, and includes: a bracket 2, an air distribution pipe 3 and a static eliminator 4;

[0035] Wherein, the bracket 2 is fixed to the aluminum film conveying assembly;

[0036] The gas distribution pipe 3 is arranged on the bracket 2, and an exhaust hole is arranged on the gas distribution pipe 3. The gas distribution pipe 3 is connected with the gas supply component, and the gas supply component is used to introduce gas into the gas distribution pipe 3 and discharge the gas from the exhaust hole;

[0037] The static eliminator 4 is disposed on the support 2 , and is used to ionize the gas in the gas distribution pipe 3 to form positively charged ions 15 or negatively charged ions 16 .

[0038] For details, please refer to the attached Figure 1 With attached Figure 3 The bracket 2 is a strip structure and is arranged on the aluminum film conveying component. The air distribution pipe 3 is arranged parallel to the bracket 2 and installed on the bracket 2. The air distribution pipe 3 is provided with an exhaust hole in the direction of the aluminum film 1. The air supply component is connected with the air distribution pipe 3. The air supply component can introduce a sufficient amount of gas into the air distribution pipe 3 and discharge the gas from the air distribution pipe 3. The bracket 2 is also provided with a static eliminator 4. The static eliminator 4 can ionize the gas in the air distribution pipe 3 to form charged positive ions 15 and charged negative ions 16. The charged positive ions 15 and the charged negative ions 16 are blown to the surface of the aluminum film 1 carrying static electricity along with the air supply of the air supply component. The charged positive ions 15 and the charged negative ions 16 carry opposite charges in the air around the aluminum film 1. Since static electricity is caused by the charge on the surface of an object, when the surrounding air carries opposite charges, these charges will neutralize the charge on the surface of the aluminum film 1, thereby achieving the effect of removing static electricity on the surface of the aluminum film 1.

[0039] On the basis of the above-mentioned embodiment, it also includes an electrode feedback sensor 6 arranged in the aluminum film conveying assembly. The electrode feedback sensor 6 is used to detect the potential of the position of the aluminum film 1 when it corresponds to it. The electrode feedback sensor 6 is electrically connected to the static eliminator 4 through the sensor cable 7.

[0040] For details, please refer to the attached Figure 3 The electrode feedback sensor 6 arranged at a position 10-20mm above the aluminum film conveying component can detect the potential of the surface of the aluminum film 1. The electrode feedback sensor 6 is electrically connected to the static eliminator 4, and transmits the detected surface potential of the aluminum film 1 to the static eliminator 4. The static eliminator 4 ionizes the corresponding positively charged ions 15 or negatively charged ions 16 according to the surface potential of the aluminum film 1. For example, when the electrode feedback sensor 6 detects that the surface of the aluminum film 1 is at a negative potential, the static eliminator 4 ionizes the positively charged ions 15, and blows the positively charged air in the air distribution pipe 3 to the surface of the aluminum film 1 through the air supply component, so that the static electricity on the surface of the aluminum film 1 is eliminated. On the contrary, when the electrode feedback sensor 6 detects that the surface of the aluminum film 1 is at a positive potential, the static eliminator 4 ionizes the negatively charged ions 16, and blows the negatively charged air in the air distribution pipe 3 to the surface of the aluminum film 1 through the air supply component, so that the static electricity on the surface of the aluminum film 1 is eliminated.

[0041] Optionally, the electrode feedback sensor 6 can use an electrostatic measuring instrument or an electrostatic potentiometer. The electrostatic measuring instrument can be aimed at the object to be measured to measure the static electricity. The electrostatic potentiometer can measure the electrostatic potential difference on the surface of the aluminum film 1, and can accurately detect whether the aluminum film 1 carries electrostatic charge and display the potential value on a digital display screen.

[0042] On the basis of the above embodiment, a first bracket 8, a second bracket 9 and a third bracket 10 are provided on the bracket 2. The first bracket 8 and the third bracket 10 are respectively provided on both sides of the bracket 2, and the second bracket 9 is provided in the middle of the bracket 2. The bracket 2 is provided on the aluminum film conveying assembly through the first bracket 8, the second bracket 9 and the third bracket 10.

[0043] Specifically, the aluminum film 1 itself has a certain width. A first bracket 8, a second bracket 9 and a third bracket 10 are arranged on the bracket 2. The three brackets cooperate to realize the positioning of the bracket 2 on the aluminum film conveying assembly. Generally speaking, the bracket 2 is arranged above the aluminum film 1, and the first bracket 8, the second bracket 9 and the third bracket 10 have the same height to ensure that the distribution pipe 3 is arranged parallel to the aluminum film, so that the charged positive ions 15 and the charged negative ions 16 can be evenly transferred to the surface of the aluminum film 1.

[0044] On the basis of the above-mentioned embodiment, the bracket 2 is rotatably connected to the first bracket 8 , the second bracket 9 , and the third bracket 10 , and the angle between the center line of the exhaust hole and the aluminum film 1 is 60°.

[0045] For details, please refer to the attached Figure 2 The bracket 2 is rotatably connected to each bracket, and a positioning component is provided between the bracket 2 and each bracket. Generally speaking, the exhaust hole on the bracket 2 has an angle of 60° between its center line and the aluminum film 1 (not shown in the figure), that is, the center line of the exhaust hole is perpendicular to the aluminum film 1 and tilted 30° to the side. Taking the aluminum film 1 as an example, the exhaust hole is tilted so that the bracket 2 can be set in front of the aluminum film 1, so that the electrode feedback sensor 6 can complete the steps of potential detection of the aluminum film 1, signal transmission, ionization of the static eliminator 4, and inflation of the air supply component, so as to ensure that the aluminum film 1 can complete the elimination of static electricity.

[0046] On the basis of the above embodiment, a plurality of exhaust holes are provided, and the exhaust holes are evenly distributed on the lower side of the bracket 2 , and the distance between two exhaust holes at the outermost edge of the bracket 2 is the same as the width of the aluminum film 1 .

[0047] Specifically, the length of the gas distribution pipe 3 needs to be set according to the width of the aluminum film 1, and multiple exhaust holes are set on the gas distribution pipe 3, and the multiple exhaust holes are evenly arranged along the gas distribution pipe 3 to ensure that the charged positive ions 15 and the charged negative ions 16 discharged from the exhaust holes can be fully sprayed onto the surface of the aluminum film 1.

[0048] On the basis of the above embodiment, an electrode needle cartridge 11 is provided at each exhaust hole.

[0049] Specifically, the electrode needle card box 11 is set at the exhaust hole, which can quickly remove the static electricity at the exhaust hole. The electrode needle card box 11 has a built-in automatic balancing sensor, which can monitor the ions generated by the static eliminator and maintain the initial ion balance by adjusting the supply of positive and negative ions. The design of some electrode needle card boxes focuses on reducing maintenance hours, and reduces the workload of adjustment and maintenance through automatic balancing sensors.

[0050] On the basis of the above-mentioned embodiment, the electrode needle cartridge 11 is disposed on the anti-drop bottom plate 12 , and the anti-drop bottom plate 12 is fixedly connected to the bracket 2 .

[0051] Specifically, the anti-drop bottom plate 12 is a strip plate structure, and a plurality of circular holes are evenly arranged on the anti-drop bottom plate 12. An annular clamping portion is provided at the upper end of the electrode needle cartridge 11. The electrode needle cartridge 11 is installed on the anti-drop bottom plate 12 from top to bottom. The clamping portion can be used to clamp the electrode needle cartridge 11 and the anti-drop bottom plate 12. When the anti-drop bottom plate 12 is installed on the bracket 2, compared with directly installing the electrode needle cartridge 11 on the exhaust hole, the electrode needle cartridge 11 can be prevented from falling off.

[0052] In some embodiments, a dust adsorption component is also included. The dust adsorption component is a negative pressure dust suction pipe. The negative pressure dust suction pipe is arranged below the bracket 2 and is used to absorb dust on the surface of the aluminum film 1.

[0053] Specifically, the aluminum film conveying assembly includes a roller guide shaft and an aluminum film conveying roller. The aluminum film 1 is arranged on the outer periphery of the aluminum film conveying roller. The aluminum film conveying assembly is arranged on the right side of the aluminum film conveying roller. The dust adsorption assembly is arranged below the aluminum film conveying roller and the bracket 2. After the static electricity on the aluminum film 1 is eliminated, the dust on its surface loses its stickiness, and the dust can be quickly adsorbed and recovered through the dust adsorption assembly.

[0054] On the basis of the above-mentioned embodiment, the static eliminator 4 is connected to the DC power supply 13 via the cable 14 , and the outer periphery of the cable 14 is provided with a shielding component 5 .

[0055] For details, please refer to the attached Figure 4 The wiring diagram of the static eliminator 4 and the DC power supply 13 is shown in the attached figure. The voltage of the DC power supply 13 is generally 24V. A shielding component 5 is provided on the outer periphery of the cable 14. The shielding component 5 can prevent the magnetic field generated on its surface from adsorbing nearby dust. For the static eliminator 4, the automatic gear is generally selected, which can automatically balance the continuous output of charged positive ions 15 or charged negative ions 16.

[0056] On the basis of the above-mentioned embodiment, the gas supply assembly is connected to the two ends of the gas distribution pipe 3 , and gas is introduced into the gas distribution pipe 3 from both ends of the gas distribution pipe 3 .

[0057] Specifically, since a plurality of exhaust holes are provided on the air distribution pipe 3, the air supply assembly is connected to the end of the air distribution pipe 3. If the number of exhaust holes is large, the air pressure at the other end will be insufficient, and the exhaust volume of each exhaust hole cannot be uniform and the same. Therefore, it is necessary to connect both ends of the air distribution pipe 3 to the air supply assembly, so that the positive and negative ions and gases discharged from each exhaust hole can be uniform and stable.

[0058] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0059] The above is a detailed introduction to the aluminum film static elimination device for a strip bag packaging machine provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method and core ideas of the present invention. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present invention, the present invention can also be improved and modified in a number of ways, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
