Description

Technical Field

[0001] The invention relates to the field of honeycomb box processing, in particular to a processing technology of a honeycomb box. Background Art

[0002] Honeycomb boxes can meet most of the supply chains of the packaged products from suppliers to factories, factories to warehouses, factories to platform warehouses, warehouses to stores, etc. They can meet the needs of automated box sealing in production plants and can be recycled through the existing recycling network system. According to the actual recycling situation, when the required number of cycles is reached, they are crushed and granulated and put back into the raw materials for recycling.

[0003] The existing honeycomb panels will shrink after being formed and cooled, resulting in poor flatness of the final honeycomb boxes, and the aesthetics cannot meet people's pursuit. Summary of the invention

[0004] In order to overcome the deficiencies of the prior art, the present invention provides a processing technology for a honeycomb box.

[0005] The technical solution adopted by the present invention to solve its technical problem is: A processing technology for a honeycomb box, the specific operation steps of the processing technology are as follows: S1: Three extrusion molding equipments heat-melt the plastic particles and extrude them into independent upper and lower layers and a core layer in the middle; S2: Processing the core layer into a honeycomb core layer by passing the core layer through a honeycomb structure forming device; S3: heating the upper layer, the lower layer and the honeycomb core layer, and performing a first hot pressing composite of the lower layer and the honeycomb core layer by a roller to form an intermediate product; S4: The intermediate product in S3 and the upper layer are kept at the same temperature and hot pressed for the second time to form a honeycomb panel S5: Cooling the honeycomb panel naturally; S6: heating the naturally cooled honeycomb panel in S5 for a second time to eliminate internal stress; S7: cutting the honeycomb board to form a rectangular board for making a honeycomb box; S8: Cut the rectangular sheet for the second time, cut off the excess sheet, heat-melt seal the edges, and heat-press to form fold marks; S9: Fold the sheet material along the folding marks to form a honeycomb box.

[0006] The honeycomb structure forming device in step S2 is a forming roller, on which a plurality of hexagonal protrusions and inner recesses arranged at intervals are arranged, and a plurality of vacuum holes are arranged in the inner recesses.

[0007] The heating temperature in step S3 is 200°C-220°C.

[0008] The heating temperature in step S4 is 200°C-220°C.

[0009] The heating temperature in step S6 is 150° C.-190° C., and the heating time is 5-10 seconds.

[0010] The temperature of the hot cutting in step S8 is 200° C.-250° C. During the hot cutting, the edge of the honeycomb panel melts and is squeezed to form a sheet structure.

[0011] The thickness of the honeycomb core layer is 0.2 mm-1.0 mm.

[0012] The honeycomb box in step S9 comprises a front side, a rear side, a left side, a right side and a bottom, the upper ends of the left and right sides are provided with movable and foldable rocking covers, and the upper end of the rear side is provided with a movable and foldable top.

[0013] The folding marks in step S8 include fixed folds for fixing the front side, the rear side, the left side, the right side and the bottom, and movable folds for connecting the left and right sides with the swing cover, and the rear side with the top.

[0014] The active fold consists of a concave mark in the middle and convex marks on the upper and lower sides of the concave mark.

[0015] The beneficial effects of the present invention are: 1. The present invention divides the pressing of the upper layer, the lower layer and the core layer in the middle into two times, and presses them after heating them to a molten state, so that the formed honeycomb panel has high strength.

[0016] 2. After the honeycomb panel is cooled naturally, internal stress is generated. It is heated for the second time to eliminate the internal stress, so that the heat shrinkage rate decreases after cooling again, and its flatness is greatly improved.

[0017] 3. The connection between the swing cover, the top and the honeycomb box adopts alternating inward and downward folds to keep the folding stress on the inside and outside the same, so that the swing cover and the top are easy to open and close. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0021] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0022] Some embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0023] Reference Figure 1 , Figure 2 , a processing technology of a honeycomb box, the specific operation steps of the processing technology are as follows: S1: Three extrusion molding equipments heat-melt the plastic particles and extrude them into independent upper and lower layers and a core layer in the middle; S2: Processing the core layer into a honeycomb core layer by passing the core layer through a honeycomb structure forming device; S3: heating the upper layer, the lower layer and the honeycomb core layer, and performing a first hot pressing composite of the lower layer and the honeycomb core layer by a roller to form an intermediate product; S4: The intermediate product in S3 and the upper layer are kept at the same temperature and hot pressed for the second time to form a honeycomb panel S5: Cooling the honeycomb panel naturally; S6: heating the naturally cooled honeycomb panel in S5 for a second time to eliminate internal stress; S7: cutting the honeycomb board to form a rectangular board for making a honeycomb box; S8: Cut the rectangular sheet for the second time, cut off the excess sheet, heat-melt seal the edges, and heat-press to form fold marks; S9: Fold the sheet material along the folding marks to form a honeycomb box.

[0024] The honeycomb structure forming equipment in step S2 is a forming roller, and the forming roller is provided with a plurality of hexagonal protrusions and recesses arranged at intervals, and a plurality of vacuum holes are provided in the recesses. When the core layer rotates with the forming roller, the core layer is pulled forward, and correspondingly, the upper layer and the lower layer also have corresponding traction rollers to pull the upper layer and the lower layer forward. The vacuum holes are always in an air suction state. When the core layer is attached to the forming roller, the core layer seals the recess into an enclosed space, and the vacuum holes extract the air in the enclosed space to form a vacuum state. The atmospheric pressure presses the core layer into the recess to cooperate with the protrusions. When the core layer leaves the forming roller, a honeycomb structure with alternating concave and convex portions is naturally formed.

[0025] In the steps S3 and S4, the heating temperature is 200°C-220°C, and the upper layer, the lower layer and the honeycomb core layer are heated to a molten state (or the upper layer, the lower layer and the position where the honeycomb core layer contacts and compounds with the upper layer and the lower layer are heated to a molten state), and the lower layer and the honeycomb core layer are first pressed together by a first pressing roller to form an intermediate product, and then pulled forward, and then the upper layer and the intermediate product are pressed together for a second time by a second pressing roller, so as to further improve the connection strength of the honeycomb panel by hot pressing.

[0026] The two heat pressing processes are carried out in the same heating device, which is the first heating device (a temperature sensor is provided in the heating device to control the heating temperature).

[0027] The heating temperature in step S6 is 150° C.-190° C., the heating device is the second heating device, and the heating time is 5-10 seconds.

[0028] The hot cutting temperature in step S8 is 200° C.-250° C. During hot cutting, the edges of the honeycomb panel are melted and extruded to form a sheet structure, so that the edges are completely bonded and sealed without the need for additional adhesive.

[0029] The thickness of the honeycomb core layer is 0.2 mm-1.0 mm.

[0030] The natural cooling in step S5 has a shorter cooling time, which is actually the period from leaving the heating equipment in S3 and S4 to entering another heating equipment in step S6 during the production process, rather than natural cooling to room temperature.

[0031] The honeycomb box in step S9 includes a front side, a rear side, a left side, a right side and a bottom (a conventional box structure generally connects the front side, the rear side, the left side and the right side by folding marks, and a corresponding folding structure is arranged at the bottom, which is fixedly connected to the lower ends of the front side, the rear side, the left side and the right side, so that the honeycomb box after being formed can be folded into a plate shape along the corresponding folding marks again, which belongs to a common folding box structure), and a movable foldable rocker cover 2 is arranged at the upper ends of the left and right sides, and a movable foldable top 3 is arranged at the upper end of the rear side (which belongs to a conventional box structure).

[0032] The folding marks in step S8 include fixed folds for fixing the front side, the rear side, the left side, the right side and the bottom, and movable folds for connecting the left and right sides with the swing cover 2 and the rear side with the top 3.

[0033] The movable fold consists of a concave mark 4 located in the middle and convex marks 1 located on the upper and lower sides of the concave mark 4. The concave mark 4 and the convex mark 1 can be converted accordingly. For example, when the observed side is the inner side, the one located in the middle is the convex mark, and the ones located on the upper and lower sides are the concave marks. When the observed side is the outer side, the one located in the middle is the concave mark, and the ones located on the upper and lower sides are the convex marks.

[0034] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
