A high-speed film blowing machine automatic roll changing mechanism

Abstract

The invention discloses an automatic roll changing mechanism for a high-speed film blowing machine, which belongs to the field of film blowing machines. , equipped with flanging to fit the top surface of the dismantled top frame, the inner side of the heating frame is provided with a spiral wire, and the two ends of the spiral wire are connected to the side wall of the heating frame, and the two ends of the spiral wire are connected to alternating current, so The inner side of the spiral wire is provided with metal fins, the inner wall of the heating frame is provided with an installation piece, the installation piece and the inner wall of the heating frame are connected by screws, and the installation piece is provided with two liquid leakage holes , and the bottom end of the heating frame is provided with a discharge channel, the end of the installation piece passes through the discharge channel, and there is a certain gap between the bottom end of the installation piece and the discharge channel. The top is provided with a ramp plate. The viscous material of the present invention forms a double-layered film when it passes through the discharge channel.

Description

technical field [0001] The invention relates to the field of film blowing machines, in particular to an automatic roll changing mechanism of a high-speed film blowing machine. Background technique [0002] With the development of industrial technology, modern plastic film manufacturing technology has become more and more perfect. Due to the relatively large demand for plastic film, the current plastic film is mass-produced in factories. The raw material of plastic film is short fiber particles. These short fiber particles are solid, so when feeding the film blowing machine, the staff needs to transport the material frame containing short fibers to the feed port of the device, and the volume of the feed ore containing short fibers and the weight are relatively large, so it is more troublesome for the staff to transport the material frame, which is also easy to bruise the staff, which is dangerous; [0003] When the rewinding roller of the plastic film is full of materials, t...

Problems solved by technology

[0002] With the development of industrial technology, modern plastic film manufacturing technology has become more and more perfect. Due to the relatively large demand for plastic film, the current plastic film is mass-produced in factories. The raw material of plastic film is short fiber particles. These short fiber particles are solid, so when feeding the film blowing machine, the staff needs to transport the material frame containing the short fiber to the feed port of the device, and the volume of the feed mine containing the short fiber The weight and weight are relatively large, so it is more troublesome for the staff to transport the material frame, and it is easy to hurt the staff, which is dangerous to a certain extent;

[0003] When the rewinding roller of the plastic film is full of materials, the staff still needs to manually remove the material roller and replace it with a new material roller for rewinding, so for mass production needs, the process of replacing the material roller will waste A lot of operating time reduces work efficiency

[0004] Just like the film blowing machine announced in 201810402474.7, the film blowing machine equipment needs manual feeding, and the equipment cannot automatically replace the material roller, which will waste a lot of labor and increase labor costs
