Description

Technical Field

[0001] This utility model relates to a winding machine, specifically a copper bar scrap winding machine. Background Technology

[0002] In copper coil slitting production, high slitting accuracy is required. The scrap material on the side of the copper coil needs to be wound up. Since the scrap material is relatively narrow and the copper material has good ductility, it is very easy to cause the winding to loosen during winding and rewinding, which affects the winding and rewinding of the scrap material into a coil. Summary of the Invention

[0003] This invention provides a waste winding machine that is simple in structure, convenient and stable in use, and can balance the tensioning and stable winding of narrow copper strip waste.

[0004] The technical solution adopted by this utility model is as follows: a waste material winding machine, including a base, with a support frame and a power box respectively arranged at the front and rear of the base. The support frame and the power box are horizontally connected to a rotating shaft via bearings. The power box is characterized in that: a counterweight box is connected to the rear side of the power box, and an abutment shaft abutting the rear end of the rotating shaft is connected inside the counterweight box. A worm gear and a worm are provided inside the power box. The worm gear is keyed to the rotating shaft, and its two ends are positioned left and right by left and right bushings connected to the rotating shaft, respectively, within the power box. The worm gear meshes with the worm, and the worm extends out of the power box and is connected to a reduction motor supported on the base via a coupling. The rotating shaft extends forward from the support frame and is keyed to the winding machine. The frame consists of a winding machine frame with two or more winding support rods evenly distributed around its circumference and facing forward. An arc-shaped winding plate is connected to the outer side of each winding support rod. The rear end of the winding support rod is hinged to the winding machine frame, and the inner side of the front end of the winding support rod is hinged to the outer end of a winding connecting rod. The inner end of the winding connecting rod is hinged to a telescopic head. A hydraulic cylinder is connected to the counterweight box. The piston rod of the hydraulic cylinder passes through the center of the abutment shaft and the rotating shaft from back to front, extending out of the rotating shaft to connect to the telescopic head. The inner hole at the rear end of the telescopic head is fitted into the front end of the rotating shaft. Two or more axial guide grooves are formed around the circumference on the outer wall of the front end of the rotating shaft. A guide pin passes through the rear end of the telescopic head, with its inner end placed within the guide groove.

[0005] The coupling is equipped with brake pads, which are matched with a pneumatic disc brake.

[0006] The winding frame includes a frame bushing and a frame rear plate. The frame bushing passes through and connects to the center of the frame rear plate. The rotating shaft extends forward and the support frame passes through and connects to the frame bushing via a key. The rear end of the winding support rod is hinged to the frame rear plate.

[0007] The rotating shaft passes forward through the frame bushing and is screwed and tightened by two nuts.

[0008] The abutting shaft is connected to the abutting sleeve via a key, and the front and rear ends of the abutting sleeve are installed in the counterweight box via thrust ball bearings.

[0009] The support frame is connected to the rotating shaft via a tapered roller thrust bearing, and the rotating shaft is connected to the power box via a radial ball bearing and a tapered roller thrust bearing at the front and rear, respectively.

[0010] The beneficial effects of this utility model are:

[0011] 1. The rotating shaft is supported by a power box and a support frame, and the hydraulic cylinder is connected with a counterweight to effectively ensure the stable support and use of the whole machine. At the same time, tapered roller thrust bearings and radial ball bearings are used to support the rotating shaft to ensure stable rotation of the rotating shaft; the winding frame is tightened with double nuts, and the connection structure is firm.

[0012] 2. A hydraulic cylinder piston rod is connected to the telescopic head in the forward direction. The telescopic head is pushed to extend and retract by the piston rod, and the winding support rod is driven to open outward through the winding connecting rod. This satisfies the real-time tension when the rotating shaft drives the arc-shaped coil plate on the winding frame to wind the copper strip, which is conducive to stable winding.
