Description

Technical Field

[0001] This utility model relates to the field of steel wire uncoiling technology, and in particular to an uncoiling and unwinding frame with automatic function. Background Technology

[0002] The wire feeding frame is an auxiliary device in the production of standard parts and other metal products. It is used to continuously feed bundled wire materials to subsequent wire drawing machines or other machinery for further processing. The wire feeding is required to be continuous. It is widely used in the production and pre-processing of metal products such as steel wire, rope, and standard parts. However, in the existing uncoiling and feeding frames, the steel wire is only driven by the support shaft and is passively uncoiled, resulting in low efficiency. To solve the above problems, an uncoiling and feeding frame with automatic function is proposed. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an unwinding and unwinding frame with automatic function, characterized by comprising a wire unwinding frame body, a hook at the front end of the wire unwinding frame body, a support trolley below the wire unwinding frame body, a support shaft inside the wire unwinding frame body, a bearing on the support shaft, a long dial on the support shaft, a short dial on the support shaft, a pulley on the support shaft, a support sleeve at the end of the support shaft, a sprocket at the end of the support shaft, the end of the support shaft being mounted on an end support seat, a frequency converter motor on the end support seat, a speed reducer on the end support seat, and an end guide wheel on the end support seat;

[0004] Furthermore, the hook is located at the front end of the wire feeding frame and is rotatable. The upper end of the bracket trolley has a steel plate to support the wire feeding frame, and the lower end rolls on the guide rail via rollers. There are baffles on the guide rail. There are two bracket trolleys, located at the front end and middle of the wire feeding frame respectively.

[0005] Furthermore, the support shaft is located inside the wire-feeding frame and is connected by bearings. The front end of the support shaft is located in the middle of the wire-feeding frame, and the end of the wire-feeding frame is connected to the middle of the support shaft by bearings. A long dial and a short dial are fixedly installed at the rear end of the support shaft in sequence. The rear end of the support shaft has a groove, and the pulley is located in the groove. The rear end of the support shaft is connected to the support sleeve by two bearings, and the support sleeve is fixedly installed on the end support seat.

[0006] Furthermore, the support shaft is hollow, and both the long and short dials have motor-driven reversing rollers.

[0007] Furthermore, the support shaft has a sprocket at its end, and the variable frequency motor on the end support is connected to the reducer and the sprocket. There are two end guide wheels, and the two end guide wheels are set on the end support at different heights via a bracket.

[0008] The beneficial effects of this utility model are:

[0009] This invention uses a hook to hoist raw wire onto a wire feeding frame. The frame can hold two spools. Two support trolleys are pushed along guide rails to support the frame, and baffles limit their movement. The wire end is pulled from the spool, inserted into the support shaft, and extends from its end. Different height guide wheels are selected as needed. The wire end is passed around the guide wheels, through a pulley, and then sequentially through the rewinding rollers of the short and long dials. A variable frequency motor is started, driving the support shaft to rotate via a reducer and sprocket. The support shaft rotates on the wire feeding frame and end support base via four bearings. The short and long dials and pulleys rotate together with the support shaft, unwinding the wire on the spool. Simultaneously, the rewinding rollers driven by the motors on the short and long dials pull the wire outwards, achieving automatic unwinding. Automatic unwinding is achieved through the combined action of the support shaft and the motors on the short and long dials. Attached Figure Description
