Stroke control device for forming telescopic plastic tube

The invention belongs to the technical field of telescopic plastic tube tools, and in particular relates to a stroke control device for forming a telescopic plastic tube. The stroke control device comprises a stander, wherein a driving rubber roll and a driven rubber roll are arranged on the stander, the driving rubber roll is connected with a driving motor, the rear ends of the driving rubber roll and the driven rubber roll are connected with each other through a middle roll, and the driven rubber roll is hinged on the stander; a sensing support is arranged on the stander in a sliding manner, a sensing plate is hinged on the sensing support and is connected with a sensor, and the sensing plate and the sensor are positioned above the driving rubber roll and the driven rubber roll. The stroke control device has the beneficial effects that the telescopic plastic tubes can be cut off according to required lengths; automatic discharging can be realized; length control, cut-off control and discharge control of the telescopic plastic tubes are realized; and the production efficiency is improved.
