Description

Technical Field

[0001] The utility model relates to the technical field of dust reduction, in particular to an air drying device for processing color-coated aluminum coils. Background Art

[0002] During the processing of color-coated aluminum coils, air drying is a crucial step, aiming to quickly and evenly dry the coating applied on the aluminum coils before entering the subsequent processing process. In the existing air drying devices for processing color-coated aluminum coils, in order to improve the air drying efficiency, the design concept of reducing the contact area with the aluminum coils is usually adopted. The realization of this design concept usually relies on using a shaft roller group to support and fix the aluminum coils. The arrangement of the shaft roller group can effectively reduce the contact area between the aluminum coils and the device, thereby increasing the air contact on the surface of the aluminum coils and accelerating the drying process.

[0003] However, there are deficiencies in the existing technology. Since the distance between the shaft rollers is relatively large, when the aluminum coil starts to enter the air drying device, its front end part often cannot automatically and accurately be clamped between the shaft rollers. This requires the operator to manually guide the aluminum coil to ensure that it correctly enters the fixed position of the shaft rollers. This manual guiding operation not only increases the labor intensity but also may lead to inaccurate entry positions of the aluminum coil, thus affecting the air drying effect and the quality of the aluminum coil.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts belong to the protection scope of the present utility model.

[0022] As Figure 1-2 shown, a drying device for color-coated aluminum coil processing includes a first frame 1. On the left and right side walls of the top of the first frame 1, holes for passing through the aluminum coil are provided. At the top of the holes, elastic shaft rods 9 for adapting to aluminum coils of different thicknesses are fixedly connected, and at the bottom of the holes, fixed shaft rods 8 are fixedly connected;

[0023] On the top of the first frame 1, a second frame 2 is fixedly connected. On one side of the second frame 2, an air pump 3 is fixedly communicated. A plurality of flow guide pipes 4 penetrate and are fixedly connected to the top wall of the first frame 1, and the upper ends of the flow guide pipes 4 are located in the cavity of the second frame 2;

[0024] On the front and rear inner walls of the first frame 1, chutes 10 are symmetrically distributed up and down. The chutes 10 are clamped with sliders 11, and the inner ends of the sliders 11 are fixedly connected with elastic shaft rods 9.

[0025] The elastic shaft rod 9 includes a telescopic rod 91. The telescopic rod 91 is fixedly connected to the top of the hole and the inner end of the slider 11 respectively. A spring 94 is also fixedly connected to the top of the hole and the inner end of the slider 11. At the bottom of the telescopic rod 91 and the spring 94, a plate body is fixedly connected. At the bottom of the plate body, symmetric front and rear fixing plates 92 are fixedly connected. Between the fixing plates 92, a shaft rod 93 is rotatably connected;

[0026] The fixed shaft rod 8 also includes fixing plates 92. The fixing plates 92 are symmetrically distributed front and rear at the bottom of the hole. Between the fixing plates 92, a shaft rod 93 is rotatably connected.

[0027] On the outer side of the shaft rod 93 in the elastic shaft rod 9 fixedly connected to the slider 11, a limiting plate 12 is fixedly connected. The limiting plate 12 is a magnetic metal. On the top and bottom walls of the right end of the cavity of the first frame 1, fixed columns 6 are fixedly connected. At the inner end of the fixed column 6, an electromagnet 7 is fixedly connected.

[0028] The bottom horizontal heights of the plurality of flow guide pipes 4 are the same, and the top heights of the plurality of flow guide pipes 4 decrease uniformly from left to right.

[0029] At the bottom of the inner wall of the first frame 1, a heater 13 for heating the inside of the first frame 1 is fixedly connected.

[0030] On the top of the first frame 1, a groove is provided and an exhaust fan 5 for exhausting water vapor to the outside of the first frame 1 is fixedly connected.

[0031] Working principle: When in use, first clamp the head of the aluminum coil between the elastic shaft rod 9 and the fixed shaft rod 8 on the left side of the first frame body 1, and then rotate the shaft rod 93 so that the aluminum coil enters the interior of the first frame body 1. At this time, the head of the aluminum coil will enter between the elastic shaft rods 9 connected to the slider 11. During the forward movement of the aluminum coil, the shaft rod 93 will rotate, so that the limiting plate 12 will fit against and clamp the aluminum coil, and then the elastic shaft rod 9 connected to the slider 11 will stop rotating. The aluminum coil will drive the slider 11 to make a sliding linear motion in the chute 10, so that the inner wall of the aluminum coil in the first frame body 1 will not collapse downward and deviate from the predetermined track;

[0032] When the slider 11 moves to the rightmost side of the chute 10, the limiting plate 12 is exactly located between the symmetric fixed columns 6. Start the electromagnet 7 so that the limiting plate 12 is attracted and moves upward, and then drive the spring 94 in the elastic shaft rod 9 connected to the slider 11 to be compressed, so that the head of the aluminum coil is released from the clamping. At the same time, the head of the aluminum coil enters between the fixed shaft rod 8 and the elastic shaft rod 9 in the right side wall of the first frame body 1;

[0033] During the movement of the aluminum coil, start the air pump 3 and the heater 13, so that the air pump 3 inputs air into the second frame body 2, and the height of the diversion pipe 4 decreases uniformly from left to right, so that the air intake of the diversion pipe 4 is the same, and then uniformly high-temperature air-dry the surface of the aluminum material. The water vapor released by the water-based paint will accumulate on the top of the first frame body 1. Start the exhaust fan 5 to discharge the water vapor and keep the interior of the first frame body 1 dry;

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
