[0003] At present, aluminum profile production lines such as Chinese patent CN202607223U are mainly used after aluminum bars are extruded, under the action of air cooling or water cooling, under the action of the traction machine, the slide table contacts the roller, and contacts the cooling bed belt during the process of transferring materials on the cooling bed. During the extrusion process, the surface of the product is relatively soft. When the roller or belt slides relative to the product, it is easy to cause belt marks, roller marks or wear marks on the surface of the product during the transportation process; during the sawing process, aluminum chips adhere to the felt of the sawing roller, which is not easy to clean and easily causes pinhole defects on the surface of the product.

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0032] like Figure 1-2 The aluminum profile production line shown includes an extruder 400, an online quenching device 200, a traction machine 500, a straightening machine 600, a sawing machine 700 and an aging treatment furnace.

[0033] The aluminum profile production line also includes a film laminating device 100, which is arranged between the online quenching device 200 and the traction machine 500. The film laminating device 100 is used to apply film protection to the bottom surface of the aluminum profile 300 after quenching and cooling by the online quenching device 200, which can effectively avoid contact between the belt, roller and the product during the aluminum profile production process, avoid the production of defective products, reduce the defective ratio of belt marks and roller marks to nearly 100%, reduce pinhole defects by more than 90%, and reduce the total product defective rate by more than 90%.

[0034] See also Figure 3-4 The film pasting device 100 includes a bracket 1, a material rod assembly arranged on the bracket 1 and used to place a protective film roll, and a supporting roller assembly arranged on the bracket 1. The protective film 4 of the protective film roll is arranged on the supporting roller assembly, and the protective film 4 is pressed between the aluminum profile 300 and the supporting roller assembly, and covers the bottom surface of the aluminum profile 300 during the movement of the aluminum profile 300.

[0035] The support roller assembly includes a support roller 2, support bearings disposed on opposite sides of the support bracket 1 and connected to both ends of the support roller 2, and a support bearing seat disposed on the support bracket 1 and used to install the support bearing. The film pasting device 100 also includes an elastic member 5 disposed between the support bearing seat and the support bracket 1. The elastic member 5 is used to keep the support roller 2 in an active state during the film pasting process to ensure that the protective film 4 can be evenly pasted on the bottom surface of the aluminum profile 300. Specifically, the elastic member 5 is a spring, which extends in the vertical direction and is disposed between the support bearing seats at both ends of the support roller 2 and the support bracket 1.

[0036] The film laminating device 100 also includes a tensioning roller assembly arranged between the material rod assembly and the supporting roller assembly, and the protective film 4 is also arranged on the tensioning roller assembly. The setting of the tensioning roller assembly can prevent the protective film from shifting due to excessive air volume of the fan, thereby preventing the aluminum profile from being completely protected.

[0037] The tensioning roller assembly includes a tensioning roller 8 arranged on the bracket 1, tensioning bearings arranged on opposite sides of the bracket 1 and connected to the two ends of the tensioning roller 8 respectively, and a tensioning bearing seat arranged on the bracket 1 and used to install the tensioning bearing.

[0038] In order to make the replacement of the protective film smoother, the film sticking device also includes a spare material rod assembly arranged on the bracket 1. The spare material rod assembly and the material rod assembly are arranged at an interval, and the two are used alternately, so that the protective film can be replaced smoothly.

[0039] The material rod assembly and the spare material rod assembly respectively include a material rod 3 arranged on the bracket 1, a material rod bearing respectively arranged on opposite sides of the bracket 1 and connected to the two ends of the material rod 3, and a material rod bearing seat arranged on the bracket 1 and used for mounting the material rod bearing.

[0040] In order to facilitate the control of the relative position between the protective film 4 and the aluminum profile 300, the film pasting device 100 also includes a first limiting mechanism respectively arranged on the material rod assembly and the spare material rod assembly, and a second limiting mechanism arranged on the tensioning roller assembly. The first limiting mechanism is used to limit the sliding of the protective film roll in the length direction of the material rod assembly or the spare material rod assembly, and the second limiting mechanism is used to limit the sliding of the protective film 4 in the length direction of the tensioning roller assembly.

[0041] The first limiting mechanism includes first limiting grooves 6 respectively arranged on opposite sides of the material rod 3, and each first limiting groove 6 extends along the length direction of the material rod 3.

The second limiting mechanism also includes second limiting members 10 respectively arranged in the second limiting grooves 9 on both sides, and the protective film 4 is located between the second limiting members 10 on both sides.

[0043] The first limiting member 7 and the second limiting member 10 can be respectively formed of limiting bolts.

[0044] The width of the protective film 4 is preferably selected to be greater than the width of the aluminum profile 300, such as 20 to 30 mm greater than the width of the aluminum profile 300, to ensure that the protective film 4 can completely cover the bottom surface of the aluminum profile, and the bottom surface of the aluminum profile 300 is a plane. The protective film 4 is commercially available, and its surface is coated with an adhesive layer, so that it can be attached to the surface of the aluminum profile and can be easily torn off from the aluminum profile. The adhesive layer will not stick to the surface of the aluminum profile, thereby protecting the surface of the product and not contaminating the surface of the product.

[0045] The aluminum profile 300 extruded by the extruder 400 is subjected to quenching and cooling treatment by the online quenching device 200, so that the temperature of the aluminum profile 300 drops below 110°C, and then the protective film 4 is applied to the bottom surface of the aluminum profile 300 by the film pasting device 100, and the film pasting device 100 can ensure the stability of the film pasting position and the flatness of the film pasting quality. The aluminum profile 300 is then moved and pulled by the front and rear traction machines 500, and then moved to the front and rear straightening machines 600 for straightening through the material transfer bed, and then sawed by the sawing machine 700. The aluminum profile 300 after sawing is then subjected to aging treatment, and the protective film 4 is torn off after sawing and before aging treatment to prevent the protective film from melting due to the high aging temperature and adhering to the surface of the aluminum profile 300, thereby contaminating the aluminum profile.

[0046] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
