Technical Field

[0001] The utility model relates to the technical field of material strip processing, in particular to a feeding device. Background Art

[0002] In recent years, with the continuous expansion of the home appliance market, motor products, as important accessories of the whole machine, have been involved in more and more application fields and have become more and more widely used.

[0003] The straight bar structure of the DC motor has many advantages such as high degree of automation, high efficiency and excellent performance, which has led to the gradual increase of straight bar punching structures. The existing technology has the following disadvantages: the punching sheets of the DC motor are straight bar structures. Since the cutting size of the straight bar punching sheets is longer than that of the traditional round punching sheets and the weight is lighter, the strip is easily affected by gravity and sags downward when the strip is sent to the punch press for punching and forming. When the strip is transported, the strip may get caught on the internal boss due to the downward depression of the strip, causing damage to the silicon steel sheet and the strip. In addition, due to the high punching speed, the strip is prone to constant shaking, causing the strip to shift, resulting in abnormal size of the punching sheet, and in severe cases, the mold will be damaged.

[0004] Therefore, there is a need for a feeding device that can fix the material belt during the conveying process so that the material belt is more stable during conveyance. Utility Model Content
