[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0027] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected or indirectly connected to the other element.

It is only for the convenience of describing the present utility model, rather than indicating that the device or element must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present utility model.

[0029] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating relative importance or indicating the quantity of technical features. In the description of the present utility model, the meaning of "a plurality of" is two or more, unless otherwise specifically defined. The following describes the specific implementation of the present utility model in more detail in conjunction with specific embodiments:

[0030] As Figure 1 , Figure 2 and Figure 3 shown, the embodiment of the present utility model provides a die head air suction hood device for sucking the oil fume generated at the position of the cold roll, including an air duct 1, a main air suction port 2 and two side air suction ports 3; the main air suction port 2 is connected to the air duct 1, facing the position of the cold roll, and the length of the main air suction port 2 is not less than the length of the cold roll; the two side air suction ports 3 are connected to the air duct 1 and are respectively arranged on both sides of the main air suction port 2. The main air suction port 2 covers the entire cold roll area. Specifically, the projection of the main air suction port 2 in the length direction includes the projection of the cold roll in the length direction. The main air suction port 2 is used to suck the oil fume generated in the cold roll area. The two side air suction ports 3 are used to suck the oil fume escaping from both sides to further improve the oil fume suction effect. Preferably, the two side air suction ports 3 can be designed to face the area where the cold roll is located. The air duct 1 is used to connect with an electrostatic oil removal device. The oil fume sucked by the main air suction port 2 and the two side air suction ports 3 is transported to the electrostatic oil removal device through the air duct 1, and the electrostatic oil removal device purifies the oil fume.

[0031] As an alternative implementation of this embodiment, the die head suction hood device further includes a fixed disk 4, a fastener, and a bracket. The fixed disk 4 is fixedly connected to the air duct 1, and the fastener tightly connects the fixed disk 4 and the bracket. The fixed disk 4 is used to install and fix the die head suction hood device on the bracket so that the main suction port 2 and the two side suction ports 3 can face the position of the cold roller.

[0032] As an alternative implementation of this embodiment, the fixed disk 4 is circumferentially provided with a plurality of mounting holes 41 at intervals. The fastener passes through the mounting holes 41 to tightly connect the fixed disk and the bracket. By using different mounting holes 41, the die head suction hood device can be installed at different inclination angles, and thus it is convenient to adjust the orientations of the main suction port 2 and the two side suction ports 3 according to different working conditions.

[0033] As an alternative implementation of this embodiment, the mounting hole 41 is an arc-shaped waist hole. Within the range of the arc-shaped waist hole, fine adjustment of the inclination angle of the die head suction hood device can be achieved.

[0034] As an alternative implementation of this embodiment, the fastener is a bolt. The bolt can achieve detachable connection, which is convenient for the disassembly and installation of the die head suction hood device.

[0035] As an alternative implementation of this embodiment, an installation area is formed at an interval between the side suction port 3 and the main suction port 2, and the fixed disk 4 is arranged in the installation area.

[0036] As an alternative implementation of this embodiment, the main suction port 2 has a suction end 21 and an air outlet end 22. The suction end 21 faces the cold roller, and the air outlet end 22 is connected to the air duct 1.

[0037] As an alternative implementation of this embodiment, the width of the suction end 21 is smaller than the width of the air outlet end 22. The smaller width of the suction end 21 is used to increase the wind force at the suction end 21 and improve the absorption effect of the oil fume.

[0038] As an alternative implementation of this embodiment, the main suction port 2 further includes a first folded edge 23. The suction end 21 has an opening 211 for sucking the oil fume. The first folded edge 23 is connected to the suction end 21 and partially blocks the opening 211. After the oil fume is sucked, a small part of the oil fume will accumulate on the inner wall of the main suction port 2. Since the main suction port 2 is arranged at a certain inclination angle, the first folded edge 23 can be used to block the oil droplets from flowing out of the opening 211.

[0039] As an alternative implementation of this embodiment, the main suction port 2 further includes a second hem 24, and the second hem 24 is connected to the suction end 21 and bends outward. During the process of sucking oil fume, a small part of the oil fume will accumulate on the outer wall of the main suction port 2. Since the main suction port 2 is arranged at a certain angle, the second hem 24 can be used to block the oil droplets from flowing out from the outer wall.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
