Description

Technical Field

[0002] Corrugated cardboard is made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products and have always been the most used among various packaging products, including calcium plastic corrugated boxes. For more than half a century, corrugated boxes have gradually replaced wooden boxes and other transport packaging containers with their superior performance and good processing properties, becoming the main force of transport packaging. In addition to protecting goods and facilitating warehousing and transportation, they also play a role in beautifying and promoting goods. Corrugated boxes are green and environmentally friendly products. They are beneficial to the environment and facilitate loading and unloading and transportation.

[0003] During the packaging process, corrugated boxes usually fit the items to be packaged, but corrugated boxes are packaged with the general opening facing upward. During the packaging process, the objects to be packaged need to be lifted and placed inside the corrugated box, which is prone to damage and is time-consuming and labor-intensive. After the objects are stuffed into the box, they still need to be lifted and taken out, which is inconvenient. The items to be packaged generally need to be weighed to adapt to the packaging load-bearing capacity of the corrugated box. Weighing them one by one is not conducive to efficient production. It is also troublesome to transport them to the weighing position before and after packaging, especially in small factories with manual operations, which is not conducive to improving the packaging efficiency of cartons.

6. The high-efficiency packaging corrugated paper box according to claim 1, characterized in that: One end of the plug-in rod (19) is fixedly connected to a fixed block (30), and both sides of the fixed block (30) are fixedly connected to anti-skid pads (31). A limit spring (24) is fixedly connected between the other end of the plug-in rod (19) and the inner opening of the plug-in slot (18). The back plate section of the U-shaped outer fixed frame (26) is fixedly connected to the back plate. A third hinge (25) is provided between the two side sections of the U-shaped outer fixed frame (26) and the back plate section. The two side sections of the U-shaped outer fixed frame (26) are rotatably connected to the back plate section. The inner opening of the U-shaped outer fixed frame (26) is fixedly connected to an adhesive layer (16), and the adhesive layer (16) is bonded to the side wall (15) of the corrugated paper box. The fixed block (30) and the anti-skid pad (31) extend out of the interior of the U-shaped outer fixed frame (26), so that the plug-in rod (19) can be manually pulled out as a whole.

7. The high-efficiency packaging corrugated paper box according to claim 1, characterized in that: The jack (10) is provided inside the U-shaped PVC support plate (1), and a threaded groove (11) is provided on the other side of the inside of the third folding plate (9). The inside of the jack (10) is adapted to be inserted into an external pull rod (12), and one end of the external pull rod (12) is fixedly connected to a threaded rod (13), and the threaded rod (13) is threadedly connected to the threaded groove (11).

8. The high-efficiency packaging corrugated paper box according to claim 1, characterized in that: The external pull rod (12) and the threaded rod (13) are detachable external structures.

9. The method for using a high-efficiency packaging corrugated paper box according to any one of claims 1 to 8, characterized in that: The following steps are involved: Step 1: Take an empty corrugated cardboard box and place it on the platform. After pulling out the lower supporting slide plate (4) at the bottom, place the corrugated cardboard box above the weighing sensor (32). After inserting the pulled-out end of the lower supporting slide plate (4) into the bottom of the object to be packaged, repeatedly fold the first folding plate (6) and the second folding plate (7) inside the pulled-out lower supporting slide plate (4) in the same direction to form a triangular shape to limit one side of the object to be packaged. Step 2: Plug the external power supply into the power socket (29), the thermosetting resin (33) is cured by heat, and the heat-expandable memory metal cylinder (34) is expanded by heat to form a roller located inside the fixed bottom plate (2), which assists the packaged item to enter the top of the fixed bottom plate (2). After the external pull rod (12) and the threaded rod (13) are inserted into the inside of the jack (10) and the threaded groove (11) in sequence, the threaded rod (13) is threadedly connected to the threaded groove (11), and the lower support slide (4) and the load on the top of the lower support slide (4) are pulled to pull the packaged item into the top of the fixed bottom plate (2). At this time, the lower support slide (4) is inserted from the bottom of the weighing sensor (32), so that the top of the weighing sensor (32) is limited between the inside of the fixed bottom plate (2) and the side wall (15) of the corrugated paper box, and is located below the packaged item to measure the packaged item. Step 3: After the measurement is completed, the lower support slide (4) is pulled out again. At this time, the first sliders (27) at both ends of the third folding plate (9) at the other end of the lower support slide (4) are located inside the first slide groove (14) and slide, which can limit the lower support slide (4). After the first three sections of the lower support slide (4) are pulled out, the lower support slide (4) is flipped over so that the first three sections of the lower support slide (4) and the third folding plate (9) are in a vertical state. At this time, the lower support slide (4) is attached to one side of the corrugated cardboard box side wall (15), and the tempered glass window (28) is separated from the interior of the fixed bottom plate (2) in the absence of support. Step 4: After the lower support slide plate (4) is fitted with one side of the corrugated paper box side wall (15), the first folding plate (6) flipped to the top is folded to fit with the top box cover, so that the first magnetic plate (8) inside the first folding plate (6) is attracted and fixed to the first magnetic plate (8) inside the box cover, and then the fixing block (30) is pulled, and the flip plate (21) is flipped to fit the second magnetic plate (23) with the lower support slide plate (4), thereby achieving the limit of the lower support slide plate (4) on one side.
