Description

Technical Field

[0001] This utility model relates to the field of uncoilers, and more specifically, to a dustproof uncoiler. Background Technology

[0002] An uncoiler is a specialized piece of equipment for leveling metal sheets. It is mainly used to unwind and level steel coils and is widely used in industries such as metallurgy, machinery, and shipbuilding. It typically consists of a welded box-shaped body, a variable frequency speed-regulating motor, and a gearbox. Power is provided by the drum shaft. During the high-speed unwinding and unwinding process, the coiled material comes into contact with the rotating rollers, adjusting arc plates, etc., and there will be intense friction. This friction causes the surface of the coiled material to be scraped and peeled off, producing metal shavings. At the same time, the friction causes the metal shavings to break and oxidize, and mix with surface dust to form a large amount of dust. Existing uncoilers lack effective protection, which causes dust to permeate inside the machine, resulting in wear on the motor, bearings, and other parts inside the machine. It also contaminates the surface of the coiled material, affecting subsequent processing operations, reducing the unwinding efficiency of the uncoiler, and the large accumulation of dust inside the machine poses a safety hazard. Utility Model Content

[0003] The purpose of this invention is to provide a dustproof unwinding machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A dustproof uncoiler includes a first base, a second base, and a motor. A protective cover is fixed on the first base, and the motor is placed inside the protective cover. A support frame is fixed on the first base, and a flange bearing is installed on the support frame. A limiting plate is fixed on one end face of the flange bearing, and a rotating roller is installed on one side of the limiting plate. Several adjusting arc plates are arranged on the outer side of the rotating roller. A rotating plate is fixed on the rotating roller, and a push rod is connected to the outer wall of the rotating plate. The other side of the push rod is connected to the adjusting arc plate. A first dust sensor is provided on the rotating plate, and a first dust suction port is provided at the end of the rotating plate along the direction of roll movement. A second dust sensor is provided at the top inside the protective cover, and a second dust suction port is provided on the surface of the first base.

[0006] Through the above technical solution, the limiting plate can prevent the roller from moving axially, and the sealing sleeve can prevent the push rod from being jammed by a large amount of dust, and can also reduce the wear of the push rod.

[0007] Furthermore, the first dust sensor is a laser scattering particulate sensor.

[0008] The laser scattering particulate sensor can improve the accuracy of dust detection through the above technical solutions.

[0009] Furthermore, a fixing plate is mounted on the second base, a fixing bracket is installed on the fixing plate, an adjusting rod is connected to the fixing bracket, and a load-bearing plate is fixed on the adjusting rod.

[0010] Through the above technical solution, the adjusting rod can adjust the load-bearing plate to ensure that the central axis of different specifications of roll material is always aligned with the rotating roller, which has the function of stabilizing the uncoiling operation.

[0011] Furthermore, a sealing strip, which is a silicone sealing strip, is installed on the protective cover near the two edges of the rotating roller.

[0012] Furthermore, the push rod is an electric push rod, and the connection between the push rod and the adjusting arc plate is wrapped with a sealing sleeve.

[0013] Through the above technical solution, the sealing sleeve can prevent the push rod from being jammed by a large amount of dust intrusion, and can also reduce the wear of the push rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] By setting a first dust sensor on the rotating plate and a first dust suction port at the end of the rotating plate along the direction of roll movement, the concentration of dust is monitored. By linking with the dust sensor, a large amount of dust is intercepted, preventing contamination of the roll surface.

[0016] By designing a second dust sensor and a second dust suction port inside the protective cover, dust intrusion into the motor and subsequent damage to the motor is effectively prevented. Attached Figure Description

[0025] The utility model will now be further described with reference to the accompanying drawings and specific embodiments:

[0026] Example 1:

[0027] Please see Figures 1 to 5 A dustproof uncoiling machine includes a first base 1, a second base 2, and a motor 3. A support frame 5 is fixed on the first base 1, and a flange bearing 6 is installed on the support frame 5. A limiting plate 7 is fixed to the right end face of the flange bearing 6, and a rotating roller 8 is installed on the right side of the limiting plate 7. Four symmetrical adjusting arc plates 9 are arranged on the outer side of the rotating roller 8. A rotating plate 10 is fixed on the rotating roller 8, and a push rod 11 is connected to the outer wall of the rotating plate 10. The push rod 11 is an electric push rod, and the other side of the push rod 11 is connected to the adjusting arc plate 9. A sealing sleeve 21 is wrapped around the connection between the push rod 11 and the adjusting arc plate 9. Before uncoiling, the inner diameter of the roll material is first determined. If the inner diameter of the roll material is too large, Push rod 11 will push the adjusting arc plate 9 to move radially away from the center of the roller 8. When the inner diameter of the roll is too small, push rod 11 will push the adjusting arc plate 9 to move radially closer to the center of the roller 8. When unwinding, motor 3 will drive flange bearing 6 to rotate, thereby driving limit plate 7 and roller 8 to rotate synchronously. Rotating plate 10 fixed on the surface of roller 8 pushes push rod 11 to drive adjusting arc plate 9 and roll material sleeved on adjusting arc plate 9 to unwind. The limit plate 7 has the function of preventing axial movement of roller 8, and the sealing sleeve 21 can prevent push rod 11 from being jammed by a large amount of dust, and can also reduce wear of push rod 11.

[0028] A first dust sensor 12 is provided on the rotating plate 10. The first dust sensor 12 is a laser scattering particulate sensor. A first dust suction port 13 is provided at the end of the rotating plate 10 along the moving direction of the roll material. The first dust suction port 13 contains a dust suction mechanism. When the roll material rubs against the adjusting arc plate 9 to generate dust, the dust will be dispersed along the rotation direction of the rotating plate 10. The first dust sensor 12 can monitor the concentration of dust. When the concentration of dust is too high, the first dust suction port 13 will suck in the air containing dust to prevent the dust from spreading to the rotating roller 8 and affecting its operation, thereby reducing the unwinding efficiency. Setting the first dust suction port 13 on the end of the rotating plate 10 along the moving direction of the roll material can dynamically suck in dust.

[0029] A fixing plate 16 is installed on the second base 2, a fixing bracket 17 is installed on the fixing plate 16, an adjusting rod 18 is connected to the fixing bracket 17, and a load-bearing plate 19 is fixed on the adjusting rod 18. When the uncoiler is performing uncoiling operation, the adjusting rod 18 can adjust the load-bearing plate 19 so that the central axis of the roll material of different specifications is always aligned with the rotating roller 8, which has the function of stabilizing the uncoiling operation.

[0030] A protective cover 4 is fixed on the first base 1. The motor 3 is placed inside the protective cover 4. Sealing strips 20, which are silicone sealing strips, are installed on the two sides of the protective cover 4 near the rotating roller 8. A second dust sensor 14 is installed on the top inside the protective cover 4. A second dust suction port 15 is provided on the surface of the first base 1. When the uncoiler is performing unwinding operations, some dust will diffuse towards the motor 3. Grooves are opened on both sides of the protective cover 4 near the rotating roller 8. Sealing strips 20 are installed in the grooves to block the gaps on both sides and reduce the entry of dust. The remaining dust that enters the protective cover 4 will diffuse upward. At this time, the second dust sensor 14 set on the top of the protective cover 4 can monitor the dust concentration. When the concentration is too high, the second dust suction port 15 on the surface of the first base 1 is activated to suck in the dust and prevent the dust from entering the motor 3 and causing damage to the motor 3.
