Description

Technical Field

[0001] The utility model relates to the field of sheet metal knurling machines, in particular to a sheet metal rolling machine feeding component. Background Art

[0002] Knurled metal sheets are a commonly used decorative material. They typically create a pattern by applying pressure to the metal surface. Typical processing equipment utilizes a continuous process, where the raw material is a steel coil, which is pulled through embossing rollers for knurling. During actual processing, as the diameter of the steel coil decreases, stress within the coil can be concentrated. This stress can cause the coil to straighten at its end. Since the coil is typically placed outside the roller press, this concentrated release of stress can easily lead to safety accidents. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides a sheet material roller press feeding assembly.

[0004] The utility model adopts the following technical solution: a sheet metal roller press feeding assembly, comprising a frame, a feeding roller and a pressing mechanism, wherein the feeding roller is rotatably mounted on the frame, a steel coil is sleeved on the feeding roller, and a pressing mechanism is provided at the end of the feeding roller, wherein the pressing mechanism is sleeved on the feeding roller and placed between the frame and the steel coil;

[0005] The pressing mechanism includes a limiting part and a pressing part. The limiting part is provided with a hole for the unwinding roller to pass through. The limiting part is pressed against the two ends of the steel coil. The pressing part is fixed on the limiting part and placed between the end face of the steel coil and the limiting part. The pressing part is pressed against the end face of the steel coil.

[0006] The limiting portion includes a limiting plate and an extension plate. The limiting plate is provided with a hole for the unwinding roller to pass through. When the steel coil is sleeved on the unwinding roller, the limiting plate contacts the side wall of the steel coil. The extension plate is fixed to the end of the limiting plate and extends along the axial direction of the steel coil. The pressing portion is provided on the extension plate and contacts the end face of the steel coil.

[0007] The pressing portion includes a plurality of pressing pieces, which are all arranged on the extension plate and along the edge of the steel coil. One end of the pressing piece close to the steel coil is pressed against the end surface of the steel coil.

[0008] The extension plate is provided with a plurality of threaded holes along the outer edge of the steel coil, the plurality of threaded holes are evenly distributed, and each of the pressing pieces is correspondingly inserted into one threaded hole;

[0009] The pressing piece includes an adjusting bolt and a pressing block. The adjusting bolt passes through the threaded hole and is threadedly engaged with the threaded hole. The pressing block is arranged at one end of the adjusting bolt inserted between the steel coil and the extension plate. The rotation of the adjusting bolt drives the pressing block to press against the end face of the steel coil.

[0010] A buffer pad is provided on the end surface of the pressing block that contacts the steel coil.

[0011] The frame is provided with a groove for placing the discharge roller, the end of the discharge roller placed in the groove is sleeved with a bearing, the bearing is in contact with the bottom of the groove, and the end of the frame is provided with a locking piece, which is pressed onto the outer ring of the bearing.

[0012] The locking member includes a locking plate, one end of which is hinged to the edge of the groove, and the other end of the locking plate is provided with an outwardly extending ear plate, a first fixing hole is provided on the ear plate, and a second fixing hole is provided on the frame at a position corresponding to the first fixing hole.

[0013] Compared with the existing technology, when the utility model is used, as the outer diameter of the steel coil gradually becomes smaller, the position of the pressure block needs to be adjusted regularly, so that the pressure block is always in contact with the outermost circle of the steel coil during the use of the steel coil. No matter how the steel coil is used, it can always be constrained into the shape of the steel coil, reducing the risk of sudden stress release of the steel coil and improving safety.
