Description

Technical Field

[0001] This utility model relates to the field of aluminum paper coating technology, and in particular to a uniform coating device for a PE high-barrier aluminum paper coating machine. Background Technology

[0002] High-barrier PE aluminum foil is a composite material that combines the properties of polyethylene (PE) and aluminum foil. Through a specific process, the two are bonded together to form a packaging material with high barrier properties. During the processing of high-barrier PE aluminum foil, its surface needs to be coated to improve its barrier properties, as well as its tear and puncture resistance, resulting in superior overall performance.

[0003] When coating high-barrier PE aluminum foil, a coating machine is used for the coating operation, and the coating device in the coating machine is the main component for achieving the coating. During the coating process, the high-barrier PE aluminum foil is placed on the coating machine, an appropriate amount of coating material is added, and the high-barrier PE aluminum foil moves on the coating machine while the coating device applies the coating material onto the high-barrier PE aluminum foil. However, existing coating devices, if using coating rollers for coating operations, generally have uneven coating uniformity. If coating blades are used for coating, the coating material cannot be quickly and evenly applied to the high-barrier PE aluminum foil in the early stages of coating, resulting in some areas of the high-barrier PE aluminum foil not being fully coated, which still affects the coating effect. At the same time, excess coating material will flow onto the conveyor belt and adhere to it, affecting the cleanliness of the conveyor belt and causing waste. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] like Figures 1-4 As shown, a uniform coating device for a PE high-barrier aluminum paper coating machine includes a fixed frame 1, a conveyor frame 2 at the lower end of the fixed frame 1, a top plate 3 at the upper end of the fixed frame 1, a lifting seat 4 on the fixed frame 1, a coating roller 5 connected to the lifting seat 4, a servo motor 6 installed on the top plate 3, and a drive screw 7 connected to the conveyor frame 2 on the servo motor 6. A scraping coating structure 8 is provided on the fixed frame 1, a material collection hopper 11 is provided on the inner side of the conveyor frame 2, and a discharge pipe 12 is provided at the lower end of the material collection hopper 11.

[0022] A roller 9 is provided on the inner side of the conveyor frame 2, and a conveyor belt 10 is fitted on the roller 9. A groove is provided on the conveyor frame 2, and a slider is provided on the lifting seat 4, with the slider positioned within the groove on the conveyor frame 2. A drive screw 7 passes through the lifting seat 4 and is threadedly connected to the lifting seat 4. A collection hopper 11 is located between two adjacent rollers 9, with one end of the collection hopper 11 positioned between the upper and lower surfaces of the conveyor belt 10.

[0023] When coating PE high-barrier aluminum paper using a coating machine, the PE high-barrier aluminum paper is placed on the conveyor belt 10 on the conveyor frame 2. After the coating material is placed on the PE high-barrier aluminum paper, the conveyor is started. The roller 9 runs, carrying the conveyor belt 10, thereby moving the PE high-barrier aluminum paper. When the PE high-barrier aluminum paper moves to the coating roller 5, the coating roller 5 coats the coating material, making the coating material disperse on the surface of the PE high-barrier aluminum paper. When the PE high-barrier aluminum paper moves to the scraper coating structure 8, the scraper coating structure 8 further coats the dispersed coating material, which can improve the coating uniformity. As the PE high-barrier aluminum paper moves, the entire PE high-barrier aluminum paper can be removed after coating is completed. When needed, the servo motor 6 on the top plate 3 can be activated. The servo motor 6 drives the drive screw 7, which in turn moves the lifting seat 4 within the fixed frame 1, thereby changing the height of the coating roller 5. Simultaneously, the scraper coating structure 8 is adjusted to ensure the scraper component is at the appropriate height, allowing for coating operations. During the coating process, the scraper coating structure 8 can also guide excess coating material into the collection hopper 11, which is then discharged through the discharge pipe 12 for recycling, preventing waste.

[0024] According to the above implementation scheme, the scraping coating structure 8 includes a mounting frame 801, a lifting plate 802, a guide post 803, and a V-shaped scraper 804. The mounting frame 801 is fixed on the fixed frame 1. The lifting plate 802 is fixedly connected to the guide post 803 and passes through the mounting frame 801. The V-shaped scraper 804 is installed on the lower surface of the lifting plate 802. The scraping coating structure 8 also includes an adjusting screw 805, a first adjusting wheel 806, a second adjusting wheel 807, and a residual material cleaning assembly 808. The adjusting screw 805 is fixed on the lifting plate 802 and passes through the mounting frame 801. The first adjusting wheel 806 and the second adjusting wheel 807 are threadedly connected to the adjusting screw 805. The first adjusting wheel 806 and the second adjusting wheel 807 are located above and below the mounting frame 801, respectively. The residual material cleaning assembly 808 is installed on the mounting frame 801, and the lower end of the residual material cleaning assembly 808 contacts the conveyor belt 10.

[0025] Before using the scraper coating structure 8, the excess material cleaning component 808 is adjusted to contact the edge of the PE high-barrier aluminum paper without affecting its normal movement. During coating, the V-shaped scraper 804 mounted on the lifting plate 802 applies the coating material to the PE high-barrier aluminum paper. The V-shaped scraper 804 guides the coating material in the middle of the PE high-barrier aluminum paper, allowing it to reach the edges and improving coating uniformity. Excess coating material is guided into the collection hopper 11 by the excess material cleaning component 808. When needed, the height of the adjusting screw 805 can be adjusted using the first adjusting wheel 806 and the second adjusting wheel 807. The lifting plate 802, carrying the V-shaped scraper 804, moves on the mounting frame 801 via the guide post 803, changing the position of the V-shaped scraper 804 to suit different coating thickness requirements.

[0026] The waste material cleaning assembly 808 includes a fixed plate 8081, a movable hole 8082, a movable block 8083, a connecting rod 8084, a scraper 8085, an end cap 8086, an adjusting rod 8087, and a knob 8088. The fixed plate 8081 is fixed on the mounting bracket 801. The movable hole 8082 is opened on the fixed plate 8081. The movable block 8083 is slidably disposed in the movable hole 8082. The connecting rod 8084 is fixedly connected to the scraper 8085 and is connected to the movable block 8083. The end cap 8086 is fixed on the fixed plate 8081. The adjusting rod 8087 is rotatably disposed on the fixed plate 8081 and passes through the movable block 8083 and the end cap 8086. The adjusting rod 8087 is threadedly connected to the movable block 8083. The knob 8088 is fixed to the end of the adjusting rod 8087.

[0027] When using the residual material cleaning component 808, the position of the scraper 8085 is first adjusted. During adjustment, the adjusting rod 8087 is rotated via the knob 8088 on the end cover 8086. Driven by the adjusting rod 8087, the movable block 8083 moves through the movable hole 8082 on the fixed plate 8081, thereby moving the connecting rod 8084 and the scraper 8085, so that the scraper 8085 is in contact with the edge of the PE high-barrier aluminum foil. After adjustment, when in use, the coating material falling onto the conveyor belt 10 flows under the guidance of the scraper 8085, falling from the edge of the conveyor belt 10 into the collection hopper 11, improving the recycling effect and ensuring the cleanliness of the conveyor belt 10 while avoiding waste.

[0028] It should be noted that the coating roller 5 and the scraper coating structure 8 are used for coating in a dual structure, which can increase the coating uniformity and ensure the coating effect. The scraper coating structure 8 is equipped with a lifting plate 802, guide column 803, adjusting screw 805 and adjusting wheel, which can adjust the height of V-shaped scraper 804, improving the flexibility and adaptability of use. The V-shaped scraper 804 can guide the coating in the middle position of the PE high-barrier aluminum paper to both sides, which can further increase the coating uniformity of the PE high-barrier aluminum paper. The residual material cleaning component 808 can guide and clean the coating material flowing onto the conveyor belt 10, and use the collection hopper 11 for recycling, which can ensure the cleanliness of the conveyor belt 10 and recycle to avoid waste. The adjusting rod 8087, end cover 8086, movable block 8083 and other structures can adjust the position of scraper 8085, so that scraper 8085 is as close as possible to the edge of PE high-barrier aluminum paper, ensuring the complete collection and cleaning of residual material.

[0029] The foregoing describes the working principle, features, and beneficial effects of this utility model. Those skilled in the art will understand from the foregoing that it does not limit the utility model. The embodiments and description above illustrate the basic principles and features of this utility model. Various changes and improvements can be made to this utility model while remaining consistent with its concept, and all such improvements should fall within the scope of protection claimed by this utility model.
