Electrochemical aluminum foil feeding pinch roller mechanism

Abstract

The utility model relates to the technical field of electrochemical aluminum foil transportation, in particular to an electrochemical aluminum foil feeding pinch roller mechanism which comprises a pinch roller body in a circular ring shape and further comprises two sealing plates located on the two sides of the pinch roller body, a closed air cavity is formed between the pinch roller body and the sealing plates, and a through hole communicated with the air cavity is formed in the side wall of the pinch roller body. And an air inlet pipe for feeding air into the air cavity is arranged on the sealing plate. And the closed air cavity is inflated through the air inlet pipe on the sealing plate. Air passes through the air cavity and then is exhausted from the through holes in the side wall of the pressing wheel body to form air flow. The airflow can blow away impurities adsorbed by static electricity on the surface of the electrochemical aluminum foil, and the possibility that the impurities are pressed into the surface of the aluminum foil in the conveying process of the pressing wheel is reduced. And meanwhile, the through holes in the surface of the pressing wheel do not influence the pressure applied to the electrochemical aluminum foil, so that enough friction force can be kept between the electrochemical aluminum foil and the conveying belt, and the electrochemical aluminum foil can be stably conveyed. The device can be widely applied to the technical field of electrochemical aluminum foil transportation.

Description

Technical Field

[0001] This utility model relates to the field of electroplated aluminum foil transportation technology, and more specifically, to an electroplated aluminum foil feeding and pressing roller mechanism. Background Technology

[0002] Electroplated aluminum foil is a material made by depositing a thin layer of aluminum onto the surface of a film or paper through methods such as vacuum aluminum plating or aluminum foil transfer. It has a bright metallic luster and good decorative properties, and is widely used in many fields such as packaging printing, label making, and greeting card decoration.

[0003] In the conveying process of electroplated aluminum foil, a conveyor belt and drive rollers are typically used as the power source to move the foil, with the pressure rollers acting as driven components. The main function of the pressure rollers is to apply a certain pressure to the aluminum foil, ensuring sufficient friction between the foil and the conveyor belt. This allows the foil to move stably with the conveyor belt, preventing slippage or deviation during transport.

[0004] However, because electroplated aluminum foil is prone to static electricity, it attracts impurities from the air. During the conveying of the foil by pressure rollers, these adsorbed impurities may be pressed into the foil surface, causing surface defects and significantly reducing product quality. These surface defects not only affect the aesthetic appearance of the electroplated aluminum foil but may also impact its performance in subsequent processing and use, failing to meet the demands of high-quality production and applications. Utility Model Content

[0005] In view of the problem that static electricity easily generates on the surface of electroplated aluminum foil in the existing technology, causing impurities in the air to be adsorbed on the surface of the aluminum foil; when the electroplated aluminum foil is conveyed with the aid of pressure rollers, these adsorbed impurities may be pressed into the surface of the aluminum foil; this utility model proposes an electroplated aluminum foil feeding pressure roller mechanism.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] An electroplated aluminum foil feeding pressure roller mechanism includes a pressure roller body, which is circular in shape, and two sealing plates located on both sides of the pressure roller body. A sealed air chamber is formed between the pressure roller body and the sealing plates. A through hole connected to the air chamber is opened on the side wall of the pressure roller body, and an air inlet pipe for air to enter the air chamber is provided on the sealing plate.

[0008] When the electroplated aluminum foil feeding roller mechanism is working, air is injected into the sealed air chamber through the air inlet pipe on the sealing plate. After passing through the air chamber, the gas is discharged from the through holes on the side wall of the roller body, forming an airflow. This airflow can blow away impurities adsorbed by electrostatics on the surface of the electroplated aluminum foil, reducing the possibility of impurities being pressed into the aluminum foil surface during the roller conveying process. At the same time, the through holes on the surface of the roller do not affect the pressure it applies to the electroplated aluminum foil, ensuring that sufficient friction is maintained between the electroplated aluminum foil and the conveyor belt, so that the electroplated aluminum foil can be conveyed stably.

[0009] Preferably, an annular mounting seat is fixed on the side wall of the sealing plate, and annular grooves for the annular mounting seat to be inserted are opened on both ends of the pressure roller body, and the pressure roller body can rotate around the axis of the annular mounting seat.

[0010] When the pressure roller mechanism is working, the sealing plate is fixed, and the pressure roller rotates along the axis of the annular mounting seat as the conveyor belt moves. The annular mounting seat and the annular groove cooperate to achieve better installation between the pressure roller body and the sealing plate.

[0011] Preferably, one of the sealing plates has a circular plate that extends into the air chamber fixed on its side wall. When the annular mounting seat is placed in the annular groove, one end of the circular plate abuts against the side wall of the other sealing plate. The side wall of the circular plate has a notch for airflow to pass through.

[0012] When the pressure roller mechanism is working, airflow enters the air chamber through the air inlet pipe. Since the annular plate and the sealing plate are fixed, while the pressure roller rotates, once the airflow fills the air chamber, it can only escape from the notch opened on the side wall of the annular plate. This allows for precise control of the escape position and direction of the airflow, ensuring that the airflow is concentrated to sweep the electroplated aluminum foil. In this way, the escaping airflow can specifically sweep the surface of the electroplated aluminum foil, removing impurities adsorbed by electrostatics.

[0013] Preferably, the notch is arc-shaped, and the angle of the center of the circle corresponding to the arc length is no greater than 90 degrees. When the pressure roller body is in use, one side wall of the notch is perpendicular to the ground.

[0014] During the operation of the pressure roller mechanism, airflow enters the air chamber through the inlet pipe. Since the annular plate and sealing plate are fixed while the pressure roller rotates, the airflow can only escape from the arc-shaped notch. When one sidewall of the notch is perpendicular to the ground, the airflow sweeps the surface of the electroplated aluminum foil at a specific angle. Because the central angle corresponding to the arc length is no greater than 90 degrees, the airflow can concentrate and powerfully sweep a specific area, effectively removing impurities from the surface of the electroplated aluminum foil.

[0015] Preferably, a sealing seat is fixed on the side wall of another sealing plate, and the sealing seat has a sealing groove for the annular plate to be inserted.

[0016] This insert-type sealing structure greatly enhances the air chamber's sealing performance, preventing accidental airflow leakage and ensuring sufficient and stable purging airflow. When airflow enters the air chamber through the inlet pipe, the tight fit between the annular plate and the sealing groove restricts the airflow to flow within the predetermined channel, allowing it to exit only through the notch on the annular plate, thus enabling targeted purging of the electroplated aluminum foil.

[0017] Preferably, a connecting column is fixed on the side wall of the sealing plate away from the pressure roller body, the side wall of the connecting column extends upward to form an extension, a mounting part is fixed on the end face of the extension, and a mounting plate is also included, the mounting part being fixed on the mounting plate.

[0018] The connecting post on the side wall of the sealing plate away from the pressure roller body is fixed to the mounting plate via a mounting part on its extension. This allows the entire pressure roller mechanism to be securely installed in the required position and remain stable during operation.

[0019] Preferably, it also includes bolts, and the mounting part is fixed to the mounting plate using bolts.

[0020] During assembly, align the mounting part with the mounting plate, then pass bolts through the corresponding screw holes on the mounting part and the mounting plate, and tighten the bolts to securely fix the mounting part to the mounting plate. When maintenance, replacement, or position adjustment of the pressure roller mechanism is required, simply loosen the bolts to separate the mounting part from the mounting plate; the operation is simple and quick.

[0028] Example

[0029] like Figures 1-4 As shown, this embodiment discloses an electroplated aluminum foil feeding pressure roller mechanism, which is mainly composed of a pressure roller body 110, a sealing plate 120, an air chamber 1101, an air inlet pipe 1201, an annular mounting seat 1202, a circular ring plate 1203, a sealing seat 130, a connecting column 140, a mounting part 1402, a mounting plate 150, and other components.

[0030] The pressure roller body 110 is annular. Sealing plates 120 are respectively provided on both sides of the pressure roller body 110, and the pressure roller body 110 and the sealing plates 120 together form a sealed air chamber 1101. Through holes 1102 communicating with the air chamber 1101 are evenly distributed on the side wall of the pressure roller body 110.

[0031] An annular mounting seat 1202 is fixed on the side wall of the sealing plate 120. Annular grooves 1103 are provided on both ends of the pressure roller body 110, into which the annular mounting seat 1202 can be inserted, allowing the pressure roller body 110 to rotate around the axis of the annular mounting seat 1202. A circular plate 1203 extending into the air chamber 1101 is fixed on the side wall of one of the sealing plates 120. When the annular mounting seat 1202 is inserted into the annular groove 1103, one end of the circular plate 1203 abuts against the side wall of the other sealing plate 120. An arc-shaped notch 1204 is provided on the side wall of the circular plate 1203. In this embodiment, the arc length of the notch 1204 corresponds to a central angle of 90 degrees. In actual use, the arc length can also be less than 90 degrees. When the pressure roller body 110 is in use, one side wall of the notch 1204 is perpendicular to the ground. A sealing seat 130 is fixed on the side wall of another sealing plate 120. The sealing seat 130 has a sealing groove 1301 for the circular plate 1203 to be inserted.

[0032] A connecting post 140 is fixed on the side wall of the sealing plate 120 away from the pressure roller body 110. The side wall of the connecting post 140 extends upward to form an extension 1401. A mounting part 1402 is fixed on the end face of the extension 1401. The mounting part 1402 is fixed to the mounting plate 150 by bolts 160. The specific installation process is as follows: the annular mounting seats 1202 on the two sealing plates 120 are respectively placed into the two annular grooves 1103. At this time, the annular plates 1203 are inserted into the sealing grooves 1301. Then, the mounting part 1402 is fixed to the mounting plate 150 by bolts 160.

[0033] The working principle of the electroplated aluminum foil feeding pressure roller mechanism in this embodiment is as follows:

[0034] During operation, airflow enters the air chamber 1101 through the air inlet pipe 1201 on the sealing plate 120. Since the annular plate 1203 and the sealing plate 120 are fixed, while the pressure roller moves with the conveyor belt and rotates around the axis of the annular mounting base 1202, the airflow, after filling the air chamber 1101, can only escape through the notch 1204 on the side wall of the annular plate 1203. The notch 1204 is located close to the electroplated aluminum foil and faces the direction of the incoming material. When one side wall of the notch 1204 is perpendicular to the ground, the airflow is concentrated at a specific angle and powerfully sweeps the surface of the electroplated aluminum foil, blowing away impurities adsorbed by electrostatics. Simultaneously, the through-hole 1102 on the surface of the pressure roller does not affect its application of pressure to the electroplated aluminum foil, ensuring sufficient friction between the electroplated aluminum foil and the conveyor belt for stable conveying.

[0035] In this example, the pressure roller mechanism effectively removes impurities adsorbed by electrostatic charge on the surface of the electroplated aluminum foil through airflow purging, reducing surface defects and improving product quality. The notch 1204 on the annular plate 1203 allows for precise control of the airflow's escape position and direction, making the purging more targeted and efficient.

[0036] The fit between the sealing seat 130 and the annular plate 1203 enhances the sealing performance of the air chamber 1101, ensuring sufficient and stable airflow and improving the purging effect. The design of the connecting column 140, the mounting part 1402, and the bolts 160 facilitates the installation, disassembly, and adjustment of the position and angle of the pressure roller mechanism.

[0037] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
