Description

Technical Field

[0001] This invention belongs to the field of aluminum film return transmission, specifically an aluminum film return transmission device and its working method. Background Technology

[0002] In the aluminum film production process, the aluminum film needs to be rewinded. According to the patent document with authorization announcement number "CN220222863U" and invention title "A Rewinding Equipment for Aluminum Film Production", the description states that when the aluminum film is fed into the inner side of the protective frame, the telescopic rod drives the static elimination rod to move, allowing it to contact the aluminum film. The static elimination rod is used to eliminate static electricity from the aluminum film, preventing the aluminum film from generating static electricity during the subsequent rewinding process, which would cause dust to be adsorbed on its surface. Then, the fan generates airflow, which sucks the dust and other particles attached to the surface of the aluminum film into the inner side of the rewind cavity through the through holes. Air circulates inside the rewind cavity, and because the inner side of the rewind cavity is equipped with an adsorption pad and a honeycomb plate, it can perform simple adsorption treatment on dust and other impurities in the air. Then, the adsorption plate is used for final adsorption and purification treatment of the dust. However, the following defects still exist: When removing dust from aluminum foil, static electricity is eliminated by an electrostatic eliminator, and then a fan is used to remove dust by suction. At this time, the aluminum foil is prone to bulging in the direction of negative pressure under the negative pressure generated by dust suction, which in turn causes the aluminum foil to stretch and wrinkle, affecting the flatness of the aluminum foil roll-up. Summary of the Invention

[0003] In view of the above situation and to overcome the defects of the prior art, the present invention provides an aluminum film return device and its working method, which effectively solves the problems mentioned in the background art.

The rotary power connector is electrically connected to a power source.

[0007] Preferably, one end of the rotating shaft extends through to the outside of the dust collector, and a driven gear is coaxially mounted on the end of the rotating shaft. The driven gear is located on the side of the dust collector, and two driven gears are meshed together. One of the driven gears is meshed with a driving gear on one side. The driving gear is fixedly connected to the output shaft of the rotating motor. The rotating motor is mounted on a motor mounting bracket, and the motor mounting bracket is bolted to the side wall of the dust collector.

[0008] Preferably, the air circulation component includes trapezoidal blocks symmetrically installed on the top and bottom walls of the dust collector. Two trapezoidal blocks are provided with limiting planes on their sides, and the distance between the two limiting planes is the same as the distance between the two first limiting rollers. Each of the two trapezoidal blocks is provided with a flow guide groove at its side. Two ion rods are respectively installed inside the two flow guide grooves. Each of the two flow guide grooves is provided with a flow-blocking arc surface on its side away from each other. The inner wall of the flow-blocking arc surface is in close contact with the outer wall of the ion rod, and an arc-shaped flow channel is formed between the ion rod and the flow guide groove.

[0009] Preferably, the trapezoidal block has an air inlet slot and an air outlet slot inside. One end of the air inlet slot is connected to the air inlet end of the arc-shaped flow channel, and the other end of the air inlet slot extends to the outside of the dust collector. One end of the air outlet slot is connected to the exhaust end of the arc-shaped flow channel, and the other end of the air outlet slot extends to the outside of the dust collector.

[0010] Preferably, the air circulation component includes an air inlet box installed on the top and bottom walls of the dust collector box, the air inlet box being connected to the end of the air inlet slot, an air inlet main pipe being provided on the side of the air inlet box away from the dust collector box, and an air inlet distribution pipe being installed at equal intervals between the air inlet box and the air inlet main pipe.

[0011] Preferably, a dust treatment box is fixedly installed on the top and bottom walls of the dust collection box, and a filter cartridge is fixedly installed inside the dust treatment box. The filter cartridge has filter holes evenly distributed on it. A cleaning cover is bolted to one end of the dust treatment box, and the other end of the dust treatment box is fixedly installed to the fan box. The fan box is connected to the inner cavity of the filter cartridge. A flow fan is installed inside the fan box, and a return pipe is installed between the fan box and the air inlet distribution pipe.

[0012] Preferably, an end cap is bolted to one end of the storage cylinder, a take-up roller is rotatably installed inside the storage cylinder, the end of the take-up roller away from the end cap is fixedly connected to the output shaft of the drive motor, the drive motor is fixedly installed at the end of the storage cylinder away from the end cap, and a vent pipe is installed at the top of the storage cylinder, with a valve installed on the vent pipe.

[0013] Preferably, a method for operating an aluminum film return device is as follows: S1. Installation: Pass one end of the aluminum film through the dust collector and into the storage cylinder. Install it outside the take-up roller. Use an air pump to extract the air containing dust from the storage cylinder and introduce clean air. Install the dust collector on the feed pipe with bolts. S2, Winding: Turn on the drive motor to drive the winding roller to rotate, thereby continuously winding the aluminum film. During the winding process, the aluminum film continuously passes through the inside of the dust removal box. S3. Dust Removal: Power on the two ion bars and turn on the rotating motor to drive the two ion bars to rotate relative to each other. Turn on the flow fan to drive the air to flow continuously through the arc-shaped flow channel after being filtered through the filter holes. The air is ionized under the action of the ion bars to generate ion wind. The ion wind neutralizes the static electricity after flowing through the aluminum film, eliminating static electricity, and at the same time, it carries the dust adhering to the aluminum film into the dust treatment box to achieve dust removal. S4. Unloading: After the aluminum film is wound up, remove the end cap and then unload the aluminum film that has been wound around the outside of the winding roller.

[0014] Compared with the prior art, the beneficial effects of the present invention are: In this invention, air is driven by a flow fan to enter the arc-shaped flow channel from the air inlet slot on the trapezoidal block, and then exits from the air outlet slot. The ion bar is set inside the guide channel, so that during the air flow, the air is ionized near the ion bar to form an ion wind. When it comes into contact with the aluminum film, it neutralizes the static electricity, thereby separating the dust adhering to the aluminum film and facilitating dust removal. This invention utilizes the ionization of circulating air to neutralize the static electricity on the aluminum film. As the air flows over the surface of the aluminum film, it exerts a pushing force on the dust on the film, carrying the dust away from the surface. Furthermore, the rotation of the ion bar exerts a pushing force on the surrounding air. The flow rate of the clamped ion wind as it passes over the aluminum film enhances the dust removal effect of the ion wind, thereby improving the dust removal effect on the aluminum film surface and improving the flatness of the aluminum film during rotation and winding. This invention involves carrying dust away with air into a dust treatment box, filtering it through a filter, and then recirculating it under the drive of a fan. This allows the remaining ions in the ionized air to neutralize the static electricity of the aluminum film, thereby reducing the power required to operate the ion bar and saving energy. This invention features trapezoidal blocks at both the top and bottom of the aluminum film, allowing for simultaneous dust removal on both sides of the aluminum film as the ion air flows through the upper and lower circulation channels. This improves dust removal efficiency. Simultaneously, the ion air on both sides exerts relative pressure on the aluminum film, providing support from both forces and ensuring the stability of the aluminum film's movement. This prevents wrinkles and improves the stability of the aluminum film's winding. Furthermore, the relative blowing dust removal method, compared to suction dust removal, prevents the aluminum film from bulging in the suction direction due to negative pressure.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0018] Example 1, by Figures 1-7 The present invention relates to an aluminum film return device, comprising a base 1, wherein an aluminum film winding assembly 2 is mounted on the top of the base 1.

[0019] The aluminum film winding assembly 2 includes a storage cylinder 201 fixedly installed at the top of the base 1. A feed pipe 205 is installed on one side of the storage cylinder 201. An end cap 202 is bolted to one end of the storage cylinder 201. A winding roller 203 is rotatably installed inside the storage cylinder 201. The end of the winding roller 203 away from the end cap 202 is fixedly connected to the output shaft of the drive motor 204. The drive motor 204 is fixedly installed at the end of the storage cylinder 201 away from the end cap 202. A vent pipe 206 is installed at the top of the storage cylinder 201. A valve 207 is installed on the vent pipe 206. One end of the vent pipe 206 is connected to an air pump. The valve 207 is opened, and the original air inside the storage cylinder 201 is discharged by the air pump. Then, clean air is introduced to reduce the dust in the air inside the storage cylinder 201 and effectively reduce the dust adhering during the aluminum film return winding process. An aluminum film dust removal assembly 3 is installed at the end of the feed pipe 205.

[0020] The aluminum foil dust collection assembly 3 includes a dust collection box 301. A feed inlet 302 is provided on the side of the dust collection box 301 away from the storage cylinder 201. A connecting frame 303 is installed on the side of the dust collection box 301 near the storage cylinder 201. The connecting frame 303 is bolted to the feed pipe 205. An ion air forming element 306 is provided inside the dust collection box 301. Air circulation elements 307 are installed on the inner top and bottom walls of the dust collection box 301. The ion air forming element 306 is installed between the two air circulation elements 307. The top and bottom of the dust collection box 301... Both are equipped with air circulation components 308. The inside of the feed inlet 302 is symmetrically and rotatably equipped with two first limiting rollers 304. The inside of the dust collector 301 and near the end of the storage cylinder 201 are symmetrically and rotatably equipped with two second limiting rollers 305. The distance between the two first limiting rollers 304 is the same as the distance between the two second limiting rollers 305. The aluminum film can be limited by the two first limiting rollers 304 and the two second limiting rollers 305, so that the aluminum film remains horizontal when moving between the upper and lower air circulation components 307.

[0021] The ion wind forming component 306 includes ion bars 3061 symmetrically rotatably mounted inside the dust collector 301. The flowing air is ionized by the ion bars 3061 and neutralizes the static electricity on the aluminum film. As the air flows over the aluminum film surface, it exerts a pushing force on the dust, carrying it away from the surface. Furthermore, the rotation of the ion bars 3061 exerts a pushing force on the surrounding air, increasing the flow rate of the ion wind as it passes over the aluminum film, thus improving the dust removal effect and enhancing the dust removal efficiency of the aluminum film surface. This also improves the flatness of the aluminum film during rotation and winding. The ion bars 3061 are located between the first limiting roller 304 and the second limiting roller 305, and a rotating shaft 30 is coaxially mounted on the ion bars 3061. 62. The rotating shaft 3062 is rotatably connected to the dust collector 301. A rotary power connector 3066 is installed at one end of the rotating shaft 3062. The rotary power connector 3066 is electrically connected to a power source. One end of the rotating shaft 3062 extends through to the outside of the dust collector 301. A driven gear 3063 is coaxially installed at the end of the rotating shaft 3062. The driven gear 3063 is located on the side of the dust collector 301. The upper and lower driven gears 3063 are meshed and connected. One side of one of the driven gears 3063 is meshed with a driving gear 3064. The driving gear 3064 is fixedly connected to the output shaft of the rotating motor 3065. The rotating motor 3065 is mounted on a motor mounting bracket. The motor mounting bracket is bolted to the side wall of the dust collector 301.

[0022] The air circulation component 307 includes trapezoidal blocks 3071 symmetrically installed on the top and bottom walls of the dust collector 301. Trapezoidal blocks 3071 are provided above and below the aluminum film, allowing simultaneous dust removal on both sides of the aluminum film as the ion air flows through the upper and lower circulation channels, improving dust removal efficiency. Simultaneously, the ion air on both sides generates relative pressure on the aluminum film, providing support and ensuring the stability of the aluminum film's movement, preventing wrinkles, and improving the stability of the aluminum film winding. Limiting planes 3072 are provided on the side of the two trapezoidal blocks 3071 that are close to each other. The distance between the two limiting planes 3072 is the same as the distance between the two first limiting rollers 304. A guide groove 3073 is provided at the end of each trapezoidal block 3071 that is close to each other. Two ion rods 3061 are respectively installed inside the two guide grooves 3073. A flow-blocking arc surface 3074 is provided on the side of each guide groove 3073 that is far from each other. The inner wall of the flow-blocking arc surface 3074 is flush with the ion rod. The outer wall of 3061 is tightly attached, and an arc-shaped flow channel is formed between the ion rod 3061 and the guide groove 3073. The trapezoidal block 3071 has an air inlet groove 3075 and an air outlet groove 3076 inside. Air enters the arc-shaped flow channel from the air inlet groove 3075 on the trapezoidal block 3071 and then exits from the air outlet groove 3076. The ion rod 3061 is set inside the guide groove 3073, so that during the air flow, the air near the ion rod 3061 is ionized to form an ion wind. When it comes into contact with the aluminum film, it neutralizes the static electricity, separating the dust adhering to the aluminum film, which is convenient for dust removal. One end of the air inlet groove 3075 is connected to the air inlet end of the arc-shaped flow channel, and the other end of the air inlet groove 3075 extends to the outside of the dust collector 301. One end of the air outlet groove 3076 is connected to the exhaust end of the arc-shaped flow channel, and the other end of the air outlet groove 3076 extends to the outside of the dust collector 301.

[0023] The air circulation component 308 includes an air inlet box 3081 installed on the top and bottom walls of the dust collector 301, respectively. The air inlet box 3081 is connected to the end of the air inlet slot 3075. An air inlet main pipe 3082 is provided on the side of the air inlet box 3081 away from the dust collector 301. An air inlet distribution pipe 3083 is installed at equal intervals between the air inlet box 3081 and the air inlet main pipe 3082. A dust handling box 3084 is fixedly installed on the top and bottom walls of the dust collector 301. A filter cartridge 3085 is fixedly installed inside the dust handling box 3084. Filter holes 3086 are evenly opened on the filter cartridge 3085. A cleaning device is bolted to one end of the dust handling box 3084. The cover plate 3087 and the other end of the dust handling box 3084 are fixedly installed in the fan box 3088. The fan box 3088 is connected to the inner cavity of the filter cartridge 3085. A flow fan 3089 is installed inside the fan box 3088. After the air carries away the dust, it enters the dust handling box 3084 and is then filtered through the filter holes 3086. Driven by the flow fan 3089, the air flows back, so that the remaining ions in the ionized air can neutralize the static electricity of the aluminum film again, thereby reducing the opening power of the ion bar 3061 and saving energy. A return pipe 30810 is installed between the fan box 3088 and the air inlet distribution pipe 3083.

[0024] Working principle: When in use, one end of the aluminum film passes between the two first limiting rollers 304, then between the two limiting planes 3072, then between the two second limiting rollers 305, and finally enters the inside of the storage cylinder 201 and is fixed to the outside of the take-up roller 203. Then, the dust removal box 301 is bolted to the feed pipe 205, one end of the air pipe 206 is connected to the air pump, and the valve 207 is opened. The original air inside the storage cylinder 201 is discharged by the air pump, and then clean air is introduced to reduce the dust in the air inside the storage cylinder 201, effectively reducing the dust adhering to the aluminum film during the return winding process. After winding, the end cover 202 is removed, and the wound aluminum film can be taken out from the take-up roller 203. When the aluminum film moves inside the dust collector 301, two first limiting rollers 304 and two second limiting rollers 305 limit the aluminum film. At the same time, the upper and lower surfaces of the aluminum film contact the two limiting planes 3072 respectively. The rotating motor 3065 is turned on to drive the drive gear 3064 to rotate. The drive gear 3064 is meshed with one of the driven gears 3063. The two driven gears 3063 are meshed with each other. The two driven gears 3063 are coaxially arranged with the two ion bars 3061 respectively, so that the rotation of the drive gear 3064 drives the two ion bars 3061 to rotate synchronously and in opposite directions. The rotation direction of the ion bars 3061 is from the air inlet groove 3075 to the air outlet groove 3076. When the ion bars 3061 rotate, electricity is applied to ionize the surrounding air. Then, the airflow fan 3089 is turned on, causing the air in the dust handling box 3084 to pass through the filter holes 3086 and enter the filter cartridge 3085. It then enters the main air intake pipe 3082 through the return pipe 30810, and evenly enters the air intake box 3081 from each air intake distribution pipe 3083. The air is then evenly blown into the air inlet trough 3075, from which it enters the arc-shaped flow channel. The arc-shaped flow channel is located between the ion rod 3061 and the aluminum... Between the membranes, air enters the circulation channel and forms an ion wind. After flowing over the surface of the aluminum membrane, it neutralizes the static electricity on the surface of the aluminum membrane, achieving electrostatic removal. The dust that adheres to the aluminum membrane due to static electricity is removed and enters the dust treatment box 3084 from the air discharge slot 3076 with the circulating air. Under the rotation of the ion bar 3061, the airflow speed in the arc-shaped circulation channel is increased, thereby increasing the air's thrust on the dust adhering to the aluminum membrane, improving the air's dust carrying capacity, and improving the dust removal effect of the aluminum membrane. After the air returns to the dust handling box 3084, it is filtered through the filter hole 3086 by the flow fan 3089 and then circulates again, so that the air can continuously flow over the surface of the aluminum membrane after filtration, so that the ions in the air that have not disappeared can be reused, improving the ion utilization rate and reducing the power consumption of the ion bar 3061, thus saving energy. When the ion wind blows within the upper and lower trapezoidal blocks 3071, the ion winds on the upper and lower sides generate an interaction force, thereby supporting the aluminum film, preventing the aluminum film from wrinkling under the action of the wind, improving the protection of the aluminum film, and ensuring the flatness of the aluminum film during rotation and winding.
