Description
Technical Field
[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding machine for preventing thin materials from unwinding. Background Technology
[0002] Thin materials refer to materials with relatively thin thickness, typically within a certain range. Specifically, the thickness of thin materials is usually less than or equal to a certain value. In the steel or metal materials industry, when thin materials are supplied in roll form, they are often referred to as sheets or coils.
[0003] When feeding thin materials, an uncoiler is typically used to unwind the material, followed by a leveling machine to flatten it, and finally a feeder to send the flattened material into a punch press for processing. However, typical leveling machines cannot clean or polish the input material during leveling. Some materials may have impurities on their surface, and their edges may have burrs. These impurities or burrs can exacerbate the risk of jamming or scratching the leveling rollers during leveling. Therefore, effectively cleaning and deburring the material is a crucial issue that needs to be addressed in the design of feeders to prevent the uncoiled thin materials. Utility Model Content

[0028] Based on common knowledge in the field, the above-mentioned preferred conditions can be combined arbitrarily to obtain various preferred embodiments of this utility model.
[0029] The positive and progressive effects of this utility model are as follows:

[0053] The cleaning structure 13 includes a first vacuum housing 1301, a second vacuum housing 1302, a cleaning brush 1303, an electric push rod 1304, and a vacuum tube 1305. The first vacuum housing 1301 is fixedly connected between two partition plates 14, and the second vacuum housing 1302 is slidably connected between the two partition plates 14. An electric push rod 1304 is fixedly connected between the second vacuum housing 1302 and a support plate 17.

A cleaning brush 1303 is fixedly connected on the side walls of the first and second vacuum housings 1301 and 1302.
[0054] The cleaning brush 1303 cleans the top and bottom edges of thin materials, while the suction pipe 1305 vacuums the dust and impurities generated during cleaning and polishing into the first suction housing 1301 and the second suction housing 1302. The electric push rod 1304 drives the second suction housing 1302 to rise, which in turn drives the suction pipe 1305 and the cleaning brush 1303 to rise.

The exhaust fan 1312 and two dust filters 1313 are fixedly connected to the inner side wall of the ventilation duct 1311. The exhaust fan 1312 is located between the two dust filters 1313. Dust venting pipe 1314 and dust venting pipe 1315 are respectively fixedly connected to the side walls of the two partition plates 14.

The other end of the dust venting pipe 1315 passes through the partition plate 14 and is fixedly connected to the side wall of the vacuum housing 1301.
[0056] The exhaust fan 1312 draws air, causing the suction pipes 1305 on the first suction housing 1301 and the second suction housing 1302 to suck up dust and impurities inside the first suction housing 1301 and the second suction housing 1302, and then send them into the collection box 11 for collection through the first dust pipe 1314 and the second dust pipe 1315.
[0057] The grinding structure 16 includes a motor 1601, a threaded rod 1602, a connecting block 1603, and a threaded rod 1604. The motor 1601 is fixedly connected to the side wall of the partition plate 14. The rotating end of the motor 1601 is fixedly connected to the threaded rod 1602. The other end of the threaded rod 1602 is fixedly connected to the connecting block 1603. The other end of the connecting block 1603 is fixedly connected to the threaded rod 1604. The other end of the threaded rod 1604 is rotatably connected to the side wall of the partition plate 14 on the other side.
[0058] The rotation of motor 1601 drives the rotation of threaded rod 1602, which in turn drives the rotation of connecting block 1603. Connecting block 1603 drives the rotation of threaded rod 1604, which in turn drives the two moving blocks 1614 to move.
[0059] The threads on threaded rod 1602 and threaded rod 1604 are opposite to each other.
[0060] The two moving blocks 1614 move closer to each other or further away from each other.
[0061] The grinding structure 16 includes a grinding roller 1611, a second motor 1612, a rotating rod 1613, and a moving block 1614. The grinding roller 1611 is fixedly connected to the side wall of the rotating rod 1613. The rotating rod 1613 is slidably connected in the second sliding groove 18. The rotating rod 1613 is rotatably connected to the moving block 1614. The moving block 1614 is threadedly connected to the first threaded rod 1602 and the second threaded rod 1604, respectively. The second motor 1612 is fixedly connected to the top side wall of the moving block 1614. The rotating end of the second motor 1612 is fixedly connected to the grinding roller 1611. The grinding roller 1611 is located between the inner frame of the first dust collection housing 1301 and the second dust collection housing 1302.
[0062] The moving block 1614 drives the grinding roller 1611 to move, which can better adjust the position of the grinding roller 1611 according to the width of the material. The motor 1612 rotates and drives the rotating rod 1613 to rotate. The rotating rod 1613 drives the grinding roller 1611 to rotate, and the grinding roller 1611 grinds and removes the burrs on the thin material.
[0063] In use, all electrical components mentioned in this application are externally connected to a power supply and control switch. Thin materials are fed into the leveling machine 4 via the unwinding machine 1. As the thin material moves between the first and second dust collection housings 1301 and 1302, the cleaning brush 1303 cleans the upper and lower sides of the material. Grinding rollers 1611 are located on both sides of the material. The second motor 1612 rotates, driving the rotating rod 1613 to rotate, which in turn drives the grinding rollers 1611 to rotate. 11. The rough edges of thin materials are polished and removed. The exhaust fan 1312 draws air, causing the suction pipes 1305 on the first suction housing 1301 and the second suction housing 1302 to suck up the dust and impurities generated during sweeping and polishing. The dust and impurities are then sucked into the first suction housing 1301 and the second suction housing 1302, and then sent into the collection box 11 through the first dust pipe 1314 and the second dust pipe 1315 for collection. This facilitates better cleaning and deburring of the materials and avoids the risk of rough edges and impurities on the materials aggravating the jamming or scratching of the leveling roller 9.
[0064] After cleaning, the thin material passes through the material passage 20. The shielding curtain 21 can always overlap the top of the material to shield the material passage 20, preventing dust and impurities generated during cleaning or grinding from entering the leveling roller 9 on the right side through the material passage 20. The material is leveled by the leveling roller 9. After leveling, the thin material is fed into the NC feeder 7 through the bridge 5. The NC feeder 7 transports the material to the punch press. When the leveling machine 4 is dealing with materials of different thicknesses, the electric push rod 1304 drives the second dust collection housing 1302 to rise. The second dust collection housing 1302 drives the dust collection pipe 1305 and the cleaning brush 1303 to rise. The position of the cleaning brush 1303 can be adjusted according to the thickness of the material, so that the cleaning brush 1303 always fits well against the side wall of the material.
[0065] When leveling materials of different widths, the motor 1601 rotates, driving the threaded rod 1602 to rotate. The threaded rod 1602 drives the connecting block 1603 to rotate, which in turn drives the threaded rod 1604 to rotate. The threaded rods 1602 and 1604 move the two moving blocks 1614, causing them to move closer or further apart. The moving blocks 1614 then move the grinding roller 1611, allowing for better adjustment of the grinding roller 1611's position according to the material's width. This ensures that the grinding roller 1611 always fits well against the sidewalls of the material, facilitating the cleaning structure 13 and the grinding structure 16 to handle the cleaning and grinding of materials of different specifications. This makes the leveling machine 4 more flexible in its overall operation.
