The lifting plate is slidably connected to the two sets of columns, and the second traction wheel is mounted on the lifting plate. According to the diameter of the plastic hose, the cylinder is extended, causing the lifting plate to lower the second traction wheel. The second traction wheel and the first traction wheel cooperate to compress the plastic hose. Only when the motor is started can the first traction wheel, in cooperation with the second traction wheel, pull the plastic hose, improving convenience.

[0009] Preferably, it also includes a drain pipe and a drain valve. The cold water tank is equipped with a drain pipe and a drain valve is installed on the drain pipe. When it is necessary to drain the water inside the cold water tank, the drain valve is opened to allow the water to drain out through the drain pipe, thus improving convenience.

[0010] Preferably, the device also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the base plate; the four sets of adjustable feet work together to provide stable support for the equipment and improve stability.

[0011] Preferably, the support leg is connected to the base plate by welding.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the extruder extrudes plastic hose through the extrusion head. After the initial part of the plastic hose enters the cooling assembly for cooling and shaping, the tube pulling assembly pulls the shaped plastic hose, thereby realizing the cooling, shaping and pulling of the plastic hose and improving production efficiency.
