Description

Technical Field

[0001] This utility model relates to the field of roller technology for producing insulated cardboard boxes, and in particular to a roller capable of continuously producing insulated cardboard boxes. Background Technology

[0002] Insulated cardboard boxes are a type of cardboard box with heat insulation function. Corrugated paper is needed in the production process of insulated cardboard boxes. As the outer layer structure in the production of insulated cardboard boxes, corrugated paper can protect the internal insulation material and the contents of the box from damage during transportation, handling, stacking and other processes. When using corrugated paper, rollers are needed to wind or unwind the corrugated paper.

[0003] With the development of the insulated cardboard box market, customers' demands for cardboard box sizes are becoming increasingly diversified. This has led to a growing number of width specifications for corrugated paper. Traditionally, the rollers used for corrugated paper production in insulated cardboard box production are often set to a uniform length, resulting in poor roller adaptability. If the width of the corrugated paper is less than the length of the roller, some parts at both ends of the roller will be idle, causing a waste of resources. When winding corrugated paper of different widths, rollers of different lengths need to be prepared, which increases the material and accessory costs for enterprises. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a roller capable of continuously producing insulated cardboard boxes, thereby solving the aforementioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A roller for continuous production of insulated cartons includes:

[0007] The main roller, used for winding or unwinding corrugated paper in the production process of insulated cardboard boxes, has a first splicing groove at both ends, and a first threaded protrusion is located within the first splicing groove of the main roller.

[0008] Several splicing components are detachably spliced ​​and installed in the first threaded protrusions at both ends of the main roll to extend the length of the main roll, thereby adapting to corrugated paper of different widths;

[0009] Two roller end assemblies are detachably mounted on splicing assemblies located at both ends of the main roller.

[0010] Preferably, the first splicing groove of the main roller is a hexagonal groove.

[0011] Preferably, the splicing component includes:

[0012] The splicing roller has a first splicing protrusion and a second splicing groove at both ends, the first splicing protrusion and the first splicing groove are adapted to each other, the first splicing protrusion of the splicing roller is inserted into the first splicing groove of the main roller, and the splicing roller has a first rotating cavity.

[0013] A first inner shaft is rotatably mounted in the first rotating cavity of the splicing roller. One end of the first inner shaft has a first threaded groove, and the first threaded groove of the first inner shaft is threadedly mounted on a first threaded protrusion at one end of the main roller.

[0014] The second threaded protrusion is fixedly installed at the other end of the first inner shaft.

[0015] Preferably, the second splicing groove is a hexagonal groove and has the same size as the first splicing groove of the main roller.

[0016] Preferably, the roller end assembly includes:

[0017] The end roller has a second splicing protrusion and a shaft cylinder at each end. The second splicing protrusion is hexagonal and is adapted to a second splicing groove at one end of the splicing roller. The second splicing protrusion of the end roller is inserted into the second splicing groove of the splicing roller. The end roller has a second rotating cavity.

[0018] The second inner shaft is rotatably mounted in the second rotating cavity of the end roller. One end of the second inner shaft has a second threaded groove, and the second threaded groove of the second inner shaft is threadedly mounted in the second threaded protrusion on the side of the splicing roller at the outer end of the main roller.

[0019] Preferably, the second inner shaft has a wrench groove on one side of the upper cylinder of the end roller.

[0020] Preferably, the wrench groove can be a hexagonal groove.

[0021] In this application, when extending the length of the main roller through assembly, one end of the first splicing protrusion on the splicing roller is gradually inserted into the first splicing groove of the main roller. Simultaneously, by screwing the second threaded protrusion inside the splicing roller, the first inner shaft is rotated, causing the first threaded groove at one end of the first inner shaft to be threaded onto the first threaded protrusion in the first splicing groove at one end of the main roller. This allows for the assembly and extension of the length at both ends of the main roller. Then, one end of the second splicing protrusion on the end roller is inserted into the second splicing groove at one end of the splicing roller. By screwing the second inner shaft, the second threaded groove at one end of the second inner shaft is threaded onto the second threaded protrusion in the second splicing groove at one end of the splicing roller. This achieves a fixed splicing installation between the end roller and the splicing roller, assembling them into a complete roller. This allows it to be used with corrugated paper for the production of insulated cartons of different widths, avoiding excess portions at both ends of the roller and improving the adaptability in the continuous production process of insulated cartons.

[0033] In this application, when extending the length of the main roller 100 through assembly, one end of the first splicing protrusion 2011 on the splicing roller 201 is gradually inserted into the first splicing groove 101 of the main roller 100. Simultaneously, by screwing the second threaded protrusion 203 inside the splicing roller 201, the first inner shaft 202 is rotated, causing the first threaded groove 2021 at one end of the first inner shaft 202 to be threaded onto the first threaded protrusion 1011 in the first splicing groove 101 at one end of the main roller 100. This allows for the assembly and extension of the length at both ends of the main roller 100. Afterwards, the second splicing protrusion 203 on the end roller 301 is... One end of 011 is inserted into the second splicing groove 2012 at one end of the splicing roller 201. By screwing the second inner shaft 302, the second threaded groove 3021 at one end of the second inner shaft 302 is threaded onto the second threaded protrusion 203 in the second splicing groove 2012 at one end of the splicing roller 201. This achieves a fixed splicing installation between the end roller 301 and the splicing roller 201, and enables the assembly into a complete roller. This allows it to be used with corrugated paper for the production of insulated cartons of different widths, avoiding excess parts at both ends of the roller and improving the adaptability of the insulated cartons in continuous production.
