Description

Technical Field

[0001] The present invention relates to the technical field of conveying during the production of packaging materials, and in particular to a conveying device and method for the production of packaging materials. Background Art

[0002] Packaging materials refer to materials used to manufacture packaging containers, packaging decoration, packaging printing, packaging transportation, etc. to meet product packaging requirements. These materials include metal, plastic, glass, ceramics, paper, bamboo, wild mushrooms, natural fibers, chemical fibers, composite materials and other main packaging materials, as well as coatings, adhesives, strapping tapes, decorations, printing materials and other auxiliary materials.

[0003] There are many choices of raw materials for packaging lunch boxes, the most common ones are plastic, paper and aluminum foil. For disposable lunch boxes, biodegradable materials such as PLA (polylactic acid) and starch are getting more and more attention because they can be degraded in the natural environment and reduce pollution to the environment. There are two main ways to form lunch boxes: injection molding and thermoforming. Injection molding: inject plastic particles into the mold in a molten state, and form a lunch box after molding and cooling. This process has the advantages of high manufacturing efficiency and high molding precision. Thermoforming: the pre-heated plastic sheet is stretched, blown and other processes to form a lunch box. This process has the advantages of simple molding process and low cost.

[0004] In the production of lunch boxes, lunch boxes need to be produced from multiple links including raw materials, molding process, packing, transportation, etc. The lunch boxes are shaped by the raw materials to make them in sheet form for transmission on the conveyor, and then the sheet mold is cut by the cutting mechanism, the lunch boxes are cut out from the sheet mold, and then the cut lunch boxes are transported, sorted, stacked and packed.

[0005] In the production and transportation of existing lunch boxes, a flat transport platform is often used to transport the lunch boxes step by step, and the lunch boxes are operated one by one through various links. However, such a transportation and operation method requires a large space to place the transportation machine and the operation machine, which is not suitable for factories with smaller spaces. In addition, the existing lunch box production requires multiple links of operation, which not only reduces the production rate of the lunch boxes, but also requires manual sorting of the collection of the lunch boxes after cutting.

[0006] To this end, we propose a conveying device and method for producing packaging materials. Summary of the invention

[0106] By cooperating with the flipping transport mechanism, the shearing assembly and the material shearing device, the sheet tableware mold can be cut into pieces. At the same time, after the sheet tableware mold is transported to the inside of the discharge mechanism, it is cut by the material shearing device, and the tableware is pressed and cut, and the tableware is stacked and collected. Then, through the linkage mode of transport, the operation steps of cutting, stacking and collecting are reduced, the production rate of the lunch box is increased, and the placement space of the device is reduced, thereby increasing the adaptability of the device.

10. A method for conveying packaging materials using a conveying device for producing packaging materials according to any one of claims 1 to 9, characterized in that: The steps include: S1: injection molding the raw materials, and transferring the injection-molded tableware in the form of sheets to the interior of the guide transport platform (121), and transporting the sheet-shaped tableware molds through the guide transport platforms (121) at both ends; S2: By starting the material transport drive motor (43), the material transport drive motor (43) drives the linkage belt (33) to transmit on the outer wall of the two sets of linkage wheels (123), the material transport wheel (316), the stretching wheel (322), the first flip wheel (217), the second flip wheel (218), the third flip wheel (2110) and the discharge wheel (415), the sheet tableware mold passes through the guide transport platform (121), and the sheet tableware mold enters the material transport groove (315) of the material transport plate (314), so that the linkage belt (33) continuously transports the sheet tableware mold. At this time, the flipping drive motor (221) is started, so that the flipping drive motor (221) drives the flipping plate (215) to rotate toward the rear end, deforming the linkage belt (33), and the flipping plate (215) drives the guide column (216) to slide along the inside of the arc-shaped guide groove (114), so that the guide column (216) drives the shear blade (54) to press down, cut the sheet-like tableware mold into pieces, and transport the cut-off sheet-like tableware mold to the inside of the transport partition (219) of the flipping plate (215) through the linkage belt (33); S3: by driving the flipping drive motor (221) in reverse, the sheet-like tableware mold is turned upside down, so that the tableware can be stacked and collected conveniently, and the flipping drive motor (221) drives the flipping plate (215) to flip toward the front end, and the linkage belt (33) is deformed again, and the sheet-like tableware mold is turned upside down, so that the tableware can be stacked and collected conveniently. At this time, the shear blade (54) is lifted, and at the same time, the linkage belt (33) drives the broken sheet-like tableware mold to be transported to the inside of the discharge plate (414), and by starting the lifting unit (621), the lifting unit (621) drives the pressing tool (624) to cut the broken sheet-like tableware mold, so that the tableware is cut out of the mold and placed on the surface of the lifting plate (615). At the same time, through the continuous transmission of the linkage belt (33), the remaining tableware mold can be discharged from the rear end of the discharge plate (414); S4: By repeating the above operation, the tableware is continuously cut so that the tableware is continuously stacked on the surface of the lifting plate (615), and the tableware is stacked inside the stacking box (611) in coordination with the descent of the lifting platform (614). When the stacking is completed, the stacked tableware inside the stacking box (611) is taken out through the discharge chute (613), thereby completing the operation.
