[0002] In the development history of puller, the feeding angle control technology has been the key factor affecting the product processing quality. The early puller feeding angle control mode is relatively simple and rough, which is difficult to meet the increasingly sophisticated production demand.

[0003] With the progress of technology, the puller using proximity switch to control feeding appears in the market. This control mode calculates 1 / 2 circle feeding at the highest speed, and the feeding speed is constant regardless of the change of the main shaft speed. However, this control mode has the problems of insufficient feeding precision and difficulty in realizing accurate control of feeding angle. When processing some products with strict requirements on feeding angle, errors are prone to occur, and the feeding process stability is poor. In actual production, the running speed and working state of the puller will change constantly, and the proximity switch controlled feeding mode cannot flexibly adapt to these changes, leading to the situation that the material is prone to jamming and shaking during feeding process, and the adaptability to the material is poor. Due to the instability of feeding, the material is prone to be scratched during conveying, which not only affects the appearance of the product, but also may cause material waste and increase production cost.
