Rotary forming machine for composite containers

Abstract

This invention provides a rotary forming machine for composite containers, comprising: a machine base; a feeding mechanism connected to the side of the machine base, the feeding mechanism including a base, a horizontal pushing device connected above the base, at least two feeding bins disposed above the horizontal pushing device, the two feeding bins respectively for placing paper containers and plastic containers; a first power source disposed on the machine base, the first power source driving a rotating seat to rotate; and a plurality of edge-rolling forming devices disposed on the rotating seat for edge-rolling the upper edges of paper containers and plastic containers to form a composite container.

Claims

1. A rotary forming machine for composite containers, comprising: a machine base; a feeding mechanism connected to the side of the machine base, the feeding mechanism including a base, a horizontal pushing device connected above the base, at least two feeding bins above the horizontal pushing device, the two feeding bins respectively feeding paper containers and plastic containers; a first power source disposed on the machine base, the first power source driving a rotary seat to rotate; a plurality of edge rolling forming devices disposed on the rotary seat; and a finished product picking mechanism connected to the side of the machine base, the picking mechanism including a base, a picking device connected above the base.

2. The rotary forming machine for composite containers as described in claim 1, wherein, The composite container is one of the following shapes: round, rectangular, or polygonal.

3. The rotary forming machine for composite containers as described in claim 1, wherein, The horizontal pushing device includes a guide rail connected to a power cylinder. The front end of the power cylinder has a material receiving clamp, which receives the paper container and the plastic container in the feed hopper.

4. The rotary forming machine for composite containers as claimed in claim 3, wherein a lifting cylinder is provided above the base, the lifting cylinder being connected to the guide rail of the horizontal pushing device, which can lift or lower the horizontal pushing device.

5. The rotary forming machine for composite containers as claimed in claim 1, wherein the edge rolling forming device comprises: a base, a second power source above the base, a turntable connected below the second power source, an annular groove at the bottom of the turntable and the turntable being connected to a male mold, and a plurality of edge rolling mechanisms on the side of the turntable, each edge rolling mechanism comprising: a linkage seat, an edge rolling wheel, two spring bearings and two springs; the two spring bearings are respectively connected to both sides of the linkage seat and connected by a push plate. A guide wheel is provided above the linkage seat, and the guide wheel is located in the annular rail groove. The annular rail groove has a positioning groove corresponding to each side rolling mechanism position. Each spring bearing has two ends, one end of which is fixed to the base, and the other end is connected to the side of the linkage seat by a spring. A push cylinder is connected to each side of the push plate, so that the linkage seat can generate displacement when the push cylinder pushes the push plate to move, thereby driving the guide wheel to move. The bottom of the side rolling forming device is provided with a lifting support platform, and the bottom of the lifting support platform is connected to a lifting power source.

6. The composite container rotary forming machine as claimed in claim 1, wherein the material handling device includes a guide rail connected to a power cylinder, the front end of the power cylinder having a material handling clamp, the material handling clamp being used to clamp the composite container.

7. The composite container rotary forming machine as claimed in claim 7, wherein a finished product storage bin is provided between the base and the material handling device, and the material handling clamp can move the composite container to the finished product storage bin for storage after clamping it.

8. The composite container rotary forming machine as claimed in claim 5, wherein each of the edge rolling forming devices is connected to a heater, which can push hot air to the edge of the mold via a heating conduit to soften the upper edge of the plastic container.
