Description

Technical Field

[0001] The utility model specifically relates to the technical field of waste material recycling, and particularly relates to a waste material recycling device for a film blowing machine. Background Technique

[0002] A film blowing machine is a device that makes films through processes such as heating and melting plastic particles, extrusion, and inflation; the plastic particles are added to the hopper of the film blowing machine, and through the rotation and heating of the screw, the plastic gradually melts and forms a uniform melt; the melt is extruded through the die head to form a tubular film blank, and at the same time, compressed air is introduced into the core rod center of the die head to inflate the film blank into a cylindrical film. The film goes through cooling, traction, and winding, and finally becomes a finished film.

[0003] Currently, during the collection of traditional waste materials, the edge materials cut from film blowing are effectively recycled and transported through a recycling machine. However, the traditional recycling machine cannot perform crushing treatment on the waste materials. When the recycled waste materials are transported to the melting device, it may cause incomplete melting of the waste materials, which will affect the processing quality of the film blowing machine.

[0004] After retrieval, Chinese Patent Application No. CN202022501825.5 discloses a waste material recycling device for a film blowing machine; it includes a waste material recycling machine, a recycling machine feed port, a recycling machine discharge port, a first conveying pipe, and a second conveying pipe. Two recycling machine feed ports are provided at one end of the waste material recycling machine, and a recycling machine discharge port is provided at the other end of the waste material recycling machine. The outside of the two recycling machine feed ports is connected to a first conveying pipe. The first conveying pipe includes a semi-circular sub-conveying pipe, a connecting pipe, a partition board, a connecting plate, and a pipe cover. There are two semi-circular sub-conveying pipes. Two connecting plates are symmetrically arranged on the outer side of the top of each semi-circular sub-conveying pipe, and a partition board is arranged on the inner side of the top of each semi-circular sub-conveying pipe. After the two semi-circular sub-conveying pipes are covered, they form a cylindrical main conveying pipe;

[0005] Although the structure in the above patent can effectively achieve the effective recycling effect of the edge material strips, the waste material recycling machine in the above patent cannot achieve the crushing effect on the waste materials. In this way, the waste materials conveyed from the recycling machine discharge port still need to pass through a crushing device before entering the melting device, which requires more equipment and has low working efficiency;

[0006] In view of the above situation, we provide a waste recycling device for blown film machines. In this device, the blown film is transported to the slitting assembly through the transmission rollers on the loading rack. A fixed rod is fixedly installed at the top of the slitting assembly, and a plurality of adjusting frames are fitted on the fixed rod. A cutting knife for cutting the blown film is fitted at the bottom of the adjusting frame. Through the cooperation between the adjusting frame and the fixed rod, the position between the cutting knife and the blown film can be effectively adjusted to achieve effective cutting of edge materials with different widths. The cut edge materials are transported to the waste recycling pipe on one side of the support frame. Two feeding ports are provided on the waste recycling pipe, which facilitates the simultaneous recycling of the edge materials on both sides of the blown film. One end of the waste recycling pipe is connected to the feeding port at the top of the slitting box through a connecting pipe. The bottom of the slitting box communicates with the fan through the cavity inside the transmission box body. Through the adsorption of the fan, the edge materials in the waste recycling pipe are extracted into the slitting box. Then, the driving motor drives the slitting knife to achieve the crushing treatment of the edge materials. The crushed edge materials are transported through the cavity to the inside of the fan. An outlet is installed on one side of the fan. The top of the outlet is connected to the negative pressure machine through a negative pressure adsorption pipe. Through the negative pressure machine, the crushed edge materials are adsorbed into the melting device to achieve the automatic recycling and crushing of the edge materials. Summary of the Invention
