Description

Technical Field

[0001] This utility model relates to the field of dust-proof equipment technology, and in particular to an automatic feeding dust-proof device for coated aluminum coils. Background Technology

[0002] In the automated production of coated aluminum coils, dust control is often required in the automatic feeding environment due to production demands. Roller shutter-type dust control devices are commonly used in automatic feeding processes. During operation, a safe distance of 5-10cm needs to be maintained between the device and the aluminum coil, which can easily lead to dust leakage through gaps. Furthermore, the lifting mechanism occupies considerable vertical space. Brush-sealed baffle structures also generate friction during automatic feeding, easily causing scratches on the coating surface. This severely restricts the production efficiency and yield of high-precision coated aluminum coils. Therefore, there is an urgent need for an automatic feeding dust control device for coated aluminum coils. Utility Model Content

[0010] Furthermore, the flow guiding cavity is divided into an outer cavity and an inner cavity by a partition;

[0011] The outer cavity and the inner cavity are respectively provided with the air outlet and the air inlet;

[0012] The outer cavity receives the airflow from the feed end fan, and the inner cavity receives the airflow from the discharge end fan.

[0013] Both the inner cavity and the outer cavity are equipped with adjustable air outlet brackets at their bottom ends.

[0014] Furthermore, the adjustable air outlet frame has an internal transfer air slot that communicates with the air inlet;

[0015] The area of ​​the transfer air duct is larger than the area of ​​the air outlet;

[0016] The transfer air duct is connected to the bottom surface of the ceiling mounting frame via a sliding guide rail.

[0017] Furthermore, the bottom end of the adjustable air outlet frame is provided with an air outlet mounting strip that cooperates with it, and the bottom end of the air outlet mounting strip is provided with a roller air guide frame.

[0031] Reference Figure 1-4 An automatic feeding and dust-proof device for coated aluminum coils includes: a base 1, wherein a feed end fan 11 and a discharge end fan 12 are respectively installed at the two ends of the base 1;

[0032] Two parallel conveyor rollers 2 are mounted above the base 1, and a horizontal channel for aluminum coils is formed between the two conveyor rollers 2;

[0033] A canopy mounting frame 3 is fixed directly above the base 1. The canopy mounting frame 3 has a flow guide cavity 31 inside. The bottom of the flow guide cavity 31 is symmetrically provided with a long strip-shaped air outlet 32 ​​and an air inlet 33. The opening of the air outlet 32 ​​faces the position of the conveyor roller 2. In a specific embodiment, the base 1 is made of channel steel welded into a rectangular frame. The feed end fan 11 and the discharge end fan 12 are fixed to the outer edges of the left and right ends of the base by bolts. Two conveyor rollers 2 are installed parallel above the base 1. The distance between the two rollers is larger than the width of the aluminum coil and forms a horizontal channel. The canopy mounting frame 3 is fixed directly above the base 1 by columns. The bottom of the frame has symmetrically provided long strip-shaped air outlets 32 and air inlets 33. When the aluminum coil passes horizontally through the conveyor rollers 2, the fans 11 and 12 on both sides work together with the canopy flow guide cavity 31 to achieve dynamic dust isolation by covering the surface of the aluminum coil with airflow.

[0034] The feed end fan 11 blows air upwards along the feeding direction, and the air outlet 32 ​​located at the feed end blows air downwards. The two airflows cross at the feed inlet of the aluminum coil to form an X-shaped air curtain.

[0035] The air outlet 32 ​​located at the feeding end and the airflow from the air blower 12 at the discharging end form a symmetrical X-shaped air curtain at the aluminum coil discharge outlet. In one specific embodiment, the air outlet of the feeding end air blower 11 is installed at an upward tilt of 15-45°, with the airflow pointing obliquely above the aluminum coil inlet. The air outlet 32 ​​at the feeding end of the guide cavity 31 is also tilted, with the airflow pointing obliquely below the aluminum coil inlet. The air outlet 12 at the discharging end and the air outlet 32 ​​at the discharging end of the guide cavity 31 are arranged symmetrically at the same angle. The upward airflow from the feeding end air blower 11 and the downward airflow from the guide cavity 31 converges in front of the aluminum coil inlet to form an X-shaped air curtain. The two air curtains together wrap around the aluminum coil travel area, and the dust is carried away from the working area by the airflow.

[0036] The flow guiding cavity 31 is separated into an outer cavity 311 and an inner cavity 312 by a partition 34;

[0037] The outer cavity 311 and the inner cavity 312 are respectively provided with the air outlet 32 ​​and the air inlet 33;

[0038] The outer cavity 311 receives the airflow from the feed end fan 11, and the inner cavity 312 receives the airflow from the discharge end fan 12.

[0039] The bottom ends of both the inner cavity 312 and the outer cavity 311 are provided with adjustable air outlet brackets 35.

[0040] The adjustable air outlet frame 35 has a transfer air duct 351 inside that communicates with the air inlet 33;

[0041] The area of ​​the transfer air duct 351 is larger than the area of ​​the air outlet 32;

[0042] The transfer air duct 351 is connected to the bottom surface of the ceiling mounting frame 3 via a sliding guide rail 352;

[0043] The adjustable air outlet frame 35 covers the air outlet 32 ​​or the air outlet 32 ​​+ the air inlet 33 via the guide rail 352. In a specific embodiment, a partition 34 is welded inside the flow guide cavity 31 to divide the cavity into an outer cavity 311 and an inner cavity 312, which are respectively connected to the discharge end fan 12. The adjustable air outlet frame 35 is installed at the bottom of the cavity via the guide rail 352. The cross-sectional area of ​​the internal transfer air duct 351 is 1.5 times that of the air outlet 32. Under normal working conditions, the adjustable air outlet frame 35 completely covers the air outlet 32, and the airflow is only discharged from the transfer air duct 351. By pulling the adjustable air outlet frame 35, the transfer air duct 351 can cover both the air outlet 32 ​​and the air inlet 33 at the same time, thereby changing the air volume and controlling the opening and closing of the air outlet.

[0044] The bottom end of the adjustable air outlet frame 35 is provided with an air outlet mounting strip 36 that cooperates with it, and the bottom end of the air outlet mounting strip 36 is provided with a roller air guide frame 37.

[0045] The bottom end of the ceiling mounting bracket 3 is provided with several converging plates 38, which are hinged to one side of the air outlet 32. In one specific embodiment, the air outlet mounting strip 36 is fixed to the bottom of the adjustable air outlet bracket 35 and sealed with the roller air guide bracket 37. The roller air guide bracket 37 is made of aluminum alloy round tube and can rotate freely around the axis to adjust the blowing angle of the air outlet. In addition, the converging plates 38 are installed on the side of the air outlet 32 ​​by hinges, with an adjustable angle range of 0°-60°, so as to control the coverage angle of the converging airflow. By adjusting the degree of rotational damping, the roller air guide bracket 37 can also convert the straight airflow into a spiral airflow, thereby enhancing the dust carrying capacity.

[0046] The outer cavity 311 and the inner cavity 312 are equipped with a collection filter 39. The collection filter 39 has an L-shaped structure. The end of the collection filter 39 is provided with an opening and closing cover 391 that cooperates with the ceiling mounting bracket 3. In a specific embodiment, the long side of the L-shaped collection filter 39 is attached to the side wall of the cavity. The opening and closing cover 391 is connected to the ceiling mounting bracket 3 through a magnetic sealing strip. When the dust-laden airflow passes through the filter 39, it is intercepted at the bend of the filter. The opening and closing cover 391 is opened weekly to clean the filter, or the position of the air inlet is changed and cleaned by air backflushing.

[0047] The conveyor roller 2 is mounted on the base 1 via a support frame 23. A sliding fixing groove 24 is provided between the support frame 23 and the base 1. A fixing plate 25 that cooperates with the support frame 23 is provided on the sliding fixing groove 24. In one specific embodiment, a slider is welded to the bottom of the support frame 23 and is clearance-fitted with the sliding fixing groove 24 on the base 1. The fixing plate 25 is provided with an elongated hole, and the position of the conveyor roller can be steplessly adjusted by bolts. After loosening the bolts of the fixing plate 25, the position can be quickly adjusted by pushing the support frame 23. After adjustment, the bolts are tightened with a torque wrench to ensure conveying stability.
