Description

Technical Field

[0001] This utility model relates to the field of aluminum composite panel production technology, specifically to an aluminum coil pre-cleaning device for aluminum composite panel production. Background Technology

[0002] Aluminum composite panels (ACPs) are a type of material used in packaging, building decoration, and other fields. They are composite panels with a plastic core and aluminum on both sides, and are covered with decorative and protective coatings or films. They offer advantages such as localized moisture resistance, oxidation resistance, and sound insulation. The production of ACPs generally involves processes such as material preparation, aluminum plate gluing, drying, lamination, shaping, and finished product inspection.

[0003] During the material preparation stage, aluminum sheet coils will have certain impurities such as oil, dust and oxide layer on their surface after transportation. They need to be cleaned with alkaline cleaning solution to remove surface oil and oxide layer to ensure that the aluminum sheet has strong coating adhesion during subsequent coating processes. Simply immersing the aluminum sheet in alkaline cleaning solution is not effective in removing surface oil and oxide layer, so a stronger cleaning method is required. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide an aluminum coil pre-cleaning device for aluminum composite panel production, so as to solve the problem of better removing oil stains from the surface of aluminum plates mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a pre-cleaning device for aluminum coils used in aluminum composite panel production, comprising a base, a cleaning water tank on the base, an aluminum plate inlet and an aluminum plate outlet on both sides of the top of the cleaning water tank, an aluminum coil unwinding machine on the outer side of the aluminum plate inlet, a feeding roller assembly on the lower inner side of the aluminum plate inlet, a discharging roller assembly on the lower inner side of the aluminum plate outlet, a lifting plate on the top inner side of the cleaning water tank, and an aluminum plate surface cleaning mechanism inside the cleaning water tank;

[0008] The aluminum plate surface cleaning mechanism consists of multiple rotating cleaning structures, each including an upper support, an upper cleaning motor, an upper rotating shaft, an upper cleaning head, a lower column, a lower cleaning motor, a lower rotating shaft, and a lower cleaning head. The upper support is fixed to the lower surface of the lifting plate, and the upper cleaning motor is fixed inside the upper support. The output end of the upper cleaning motor is fixedly connected to the upper rotating shaft, and the upper cleaning head is located at the bottom of the upper rotating shaft. The lower column is fixed to the bottom of the cleaning tank, and the lower cleaning motor is fixed inside the lower column. The output end of the lower cleaning motor is fixedly connected to the lower rotating shaft, and the lower cleaning head is located at the top of the lower rotating shaft.

[0010] As a preferred embodiment of this invention, an upper cleaning sponge is provided at the bottom of the upper cleaning head, and a lower cleaning sponge is provided at the top of the lower cleaning head.

[0011] As a preferred embodiment of this utility model, an upper scraper is provided on one side of the lifting plate. The upper scraper adheres to the upper surface of the aluminum plate when the lifting plate is lowered to the working position. A lower scraper is provided below the upper scraper. The lower scraper is fixed to the bottom of the cleaning water tank and adheres to the upper surface of the aluminum plate.

[0012] As a preferred embodiment of this invention, a lifting motor is provided on the top of the lifting plate, and the lifting motor is fixed on the top cover of the cleaning water tank.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 3 As shown, this utility model provides an aluminum coil pre-cleaning device for aluminum composite panel production, including a base 1, a cleaning water tank 2 on the base 1, an aluminum plate inlet 3 and an aluminum plate outlet 4 on both sides of the top of the cleaning water tank 2, an aluminum coil unwinding machine 5 on the outside of the aluminum plate inlet 3, a feeding roller group 6 on the lower inside of the aluminum plate inlet 3, a discharging roller group 7 on the lower inside of the aluminum plate outlet 4, a lifting plate 8 on the top inside of the cleaning water tank 2, and an aluminum plate surface cleaning mechanism 9 inside the cleaning water tank 2.

[0025] refer to Figure 1 and Figure 2The aluminum plate surface cleaning mechanism 9 consists of multiple rotating cleaning structures 10. Each rotating cleaning structure 10 includes an upper support 1001, an upper cleaning motor 1002, an upper rotating shaft 1003, an upper cleaning head 1004, a lower column 1005, a lower cleaning motor 1006, a lower rotating shaft 1007, and a lower cleaning head 1008. The upper support 1001 is fixed to the lower surface of the lifting plate 8. The upper cleaning motor 1002 is fixed inside the upper support 1001. The output end of the upper cleaning motor 1002 is fixedly connected to the upper rotating shaft 1003. The upper cleaning head 1004 is provided at the bottom of the upper rotating shaft 1003. The lower column 1005 is fixed to the bottom of the cleaning tank 2. The lower cleaning motor 1006 is fixed inside the lower column 1005. The output end of the lower cleaning motor 1006 is fixedly connected to the lower rotating shaft 1007. The lower cleaning head 1008 is provided at the top of the lower rotating shaft 1007.

[0026] By setting up an aluminum plate surface cleaning mechanism 9, after the aluminum plate enters the cleaning water tank 2, the lifting plate 8 descends so that the upper cleaning head 1004 and the lower cleaning head 1008 are attached to the upper and lower surfaces of the aluminum plate. As the upper cleaning motor 1002 and the lower cleaning motor 1006 work, they drive the upper cleaning head 1004 and the lower cleaning head 1008 to rotate, cleaning the upper and lower surfaces of the aluminum plate, removing oil stains and oxide layers from the surface of the aluminum plate, keeping the surface of the aluminum plate clean, and improving the adhesion of the aluminum plate surface.

[0027] refer to Figure 1 and Figure 3 An upper scraper 11 is provided on one side of the lifting plate 8. When the lifting plate 8 is lowered to the working position, the upper scraper 11 is attached to the upper surface of the aluminum plate. A lower scraper 12 is provided below the upper scraper 11. The lower scraper 12 is fixed to the bottom of the cleaning water tank 2 and is attached to the upper surface of the aluminum plate.

[0028] By installing the upper scraper 11 and the lower scraper 12, after the aluminum plate is cleaned by the aluminum plate surface cleaning mechanism 9, a large amount of cleaning liquid will remain on the surface. After the upper scraper 11 descends with the lifting plate 8, the bottom rubber scraper head A14 is attached to the upper surface of the aluminum plate, while the top rubber scraper head B15 of the lower scraper 12 is attached to the lower surface of the aluminum plate. As the aluminum plate moves forward, the two scrapers scrape off the cleaning liquid remaining on the surface of the aluminum plate and let it fall back into the cleaning water tank 2. This reduces the consumption of cleaning liquid and the energy consumption of the subsequent drying process, thus saving production costs.

[0029] How to use

[0030] The working principle and usage process of this utility model are as follows: The aluminum sheet coil is placed into the aluminum coil unwinding machine 5. After the aluminum sheet is adjusted in direction by the feeding reversing roller 16, it enters the cleaning water tank 2 through the aluminum sheet inlet 3. It then enters the aluminum sheet surface cleaning mechanism 9 via the feeding roller group 6. At this time, the lifting motor 13 controls the lifting plate 8 to descend, causing the upper cleaning head 1004 to adhere to the upper surface of the aluminum sheet. Simultaneously, the upper cleaning motor 1002 and the lower cleaning motor 1006 are started, driving the upper cleaning head 1004 and the lower cleaning head 1008 to rotate, cleaning the upper and lower surfaces of the aluminum sheet to remove oil stains and oxide layers. The upper cleaning head 100... 4. The lower cleaning head 1008 is wrapped with an upper cleaning sponge 1009 and a lower cleaning sponge 1010 to reduce friction with the aluminum plate surface. Then, the aluminum plate is discharged from the aluminum plate outlet 4 at an angle upward through the discharge roller group 7. During this process, the rubber scraper head A14 at the bottom of the upper scraper 11 adheres to the upper surface of the aluminum plate after the lifting plate 8 descends, while the rubber scraper head B15 at the top of the lower scraper 12 adheres to the lower surface of the aluminum plate. As the aluminum plate moves forward, the two scrapers scrape off the residual cleaning liquid on the surface of the aluminum plate and drop it back into the cleaning water tank 2. Finally, the aluminum plate enters the subsequent processing device after the discharge reversing roller 17 adjusts its direction.
