The soft tube has the characteristics of lightness, good sealing, easy carrying and use. According to the material of the soft tube, it can be divided into plastic soft tube, aluminum-plastic composite soft tube and paper-plastic composite soft tube.

[0003] Before the produced soft tube is used, it usually needs to be put into the soft tube pipe drawing equipment and cut or sealed to meet the application of the soft tube in different industries such as daily chemical, food and medicine.

[0056] It should be noted that when the stretching length of a single hose needs to be changed, the electric sliding block 15 is first controlled to slide to the left, at this time, the three inner supporting rods 551 on the mounting plate 55 also move to the left and are inserted into the hose, the inner support of the inner wall of the hose is realized by the three inner supporting rods 551, then the relative rotation of the two toothed belts 433 drives the hose to move to the right, at the same time, the electric sliding block 15 also drives the three inner supporting rods 551 to move to the right, ensuring that the hose does not block during movement, and the movement of the electric sliding block 15 is stopped after reaching the designated position, and the cutting work of the hose is finally completed by the rotation of the three arc-shaped cutters 332.
