Description

Technical Field

[0001] This utility model relates to the technical field of paper bags, and in particular to a honeycomb bag and its die-cutting structure. Background Technology

[0002] During the harvesting, transportation, and sale of fruits, to prevent damage to fragile fruits such as apples and pears from collisions, squeezing, or drops, traditionally, mesh sleeves made of foamed plastic (such as polyethylene or polystyrene foam) are widely used as cushioning and protective packaging. These foam mesh sleeves, by wrapping individual fruits, utilize their elastic structure to disperse external impact forces, thus reducing the rate of mechanical damage to the fruit's surface to a certain extent.

[0003] However, with increasingly stringent environmental protection requirements and the iteration of packaging technologies, the limitations of existing foam netting are becoming increasingly apparent. Traditional foam netting uses non-degradable petroleum-based plastics as raw materials, making it difficult to recycle after use and resulting in a long degradation cycle. Secondly, existing foam netting requires injection molding, which consumes significant energy and incurs high raw material costs. Therefore, to address these issues, the honeycomb bag and its die-cut structure proposed in this application are presented. Utility Model Content

[0008] Optionally, the dashed slits include a plurality of slits, each of which is distributed at equal intervals along a straight line, and the slits in any two adjacent dashed slits are staggered.

[0009] Optionally, the dashed cuts are equidistant from each other.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] This utility model discloses a honeycomb bag and its die-cutting structure, comprising two face sheets stacked together with their three adjacent edges bonded together. Each face sheet has several spaced dotted slits, with any two adjacent slits staggered. When the two face sheets are moved apart by an external force, they form a mesh structure through the dotted slits. Thus, when the two face sheets move apart, the bag forms a cylindrical mesh structure through the dotted slits. The face sheets deform into a three-dimensional structure under the action of the dotted slits, effectively protecting the contents such as fruit. Because the raw material is paper, compared to existing foamed mesh bags, this honeycomb bag is lower in cost, more environmentally friendly, and only requires cutting a flat paper bag, making production easier.

[0029] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0030] like Figure 1 As shown, a honeycomb bag 20 includes two face sheets 21, which are stacked together and the three adjacent edges of the two face sheets 21 are bonded together. Each face sheet 21 has a number of spaced dotted slits, and any two adjacent dotted slits are staggered. When the two face sheets 21 are moved away from each other by an external force, the two face sheets form a mesh structure through the dotted slits.

[0031] It should be noted that the face paper 21 has a rectangular structure, with one short side and two long sides glued and fixed together, forming a single-end open paper bag structure. Multiple through-line slits are then made on the face paper 21, with the slits spaced apart and staggered in pairs. Each slit extends from one end of the face paper 21 to the other. Thus, when fruit is placed between the two face papers 21, causing them to move away from each other, the paper bag forms a mesh-like structure through the slits. The face paper 21 deforms into a three-dimensional structure under the action of the slits, thereby protecting the fruit and other contents. Since the raw material is paper, compared to existing foam mesh sleeves, the honeycomb bag 20 of this application is lower in cost, more environmentally friendly, and only requires cutting a flat paper bag, making production easier.

[0032] like Figure 1 As shown, in one embodiment, the dashed slit includes a plurality of cuts 21a, each cut 21a being distributed at equal intervals along a straight line, and the cuts 21a in any two adjacent dashed slits being staggered.

[0033] Thus, the cuts 21a are staggered, and when the two face sheets 21 are deformed by external force, the face sheets 21 are transformed into a three-dimensional mesh paper bag through the cuts 21a. Further, in one embodiment, the dotted slits are equidistantly distributed. This results in each cut 21a in the formed mesh paper bag having the same four-sided perforated structure, thereby better protecting the fruit while ensuring breathability.

[0034] like Figures 2 to 4 As shown, a honeycomb bag die-cutting structure 10 includes a substrate 100, a buffer assembly 200, and a punching assembly 300. A material carrier plate 400 is detachably disposed on the substrate 100. The material carrier plate 400 has two through holes (shown as dashed lines). The buffer assembly 200 includes a pressure plate 210 and a buffer elastic member 220. The pressure plate 210 is slidably disposed on the substrate 100 along the normal direction. The buffer elastic member 220 abuts against the substrate 100 and the pressure plate 210 respectively. The pressure plate 210 has a plurality of second through holes 211. Each second through hole 211... Aligned with each dotted through hole, the punching assembly 300 includes a punching plate 310, a punching elastic member 320, and several cutters 330. The punching plate 310 is slidably disposed on the side of the pressure plate 210 away from the substrate 100 along the normal direction. The punching elastic member 320 abuts against the punching plate 310 and the pressure plate 210 respectively, and the elastic coefficient of the punching elastic member 320 is greater than the elastic coefficient of the buffer elastic member 220. Each cutter 330 is disposed on the punching plate 310, and each cutter 330 is aligned with each second through hole 211.

[0035] It should be noted that the face paper 21 is usually fed in rolls, so the long strip of double-sided face paper 21 passes through the carrier plate 400 and the pressure plate 210 for conveying. When the face paper 21 stops, the punching plate 310 drives the cutter 330 to press down and approach the carrier plate 400. Since the elastic coefficient of the punching elastic element 320 is greater than that of the buffer elastic element 220, the distance between the punching plate 310 and the pressure plate 210 remains unchanged for a short time. The pressure plate 210 follows the punching plate 310 to approach the carrier plate 400 to compress the buffer elastic element 220, and then the pressure plate 210 abuts against the carrier plate 400 to press the face paper 21. At this time, the pressure plate 210 no longer moves. As the punching plate 310 continues to descend, the punching elastic element 320 is compressed, and each cutter 330 mounted on the punching plate 310 passes through the second through hole 211, cuts through the double-sided face paper 21, and extends into the dotted through hole. Finally, the punching plate 310 drives the cutter 330 to rise and reset. The punching elastic element 320 resets before the buffer elastic element 220, so the pressure plate 210 remains in a state of pressing the face paper 21. The punching plate 310 drives the cutter 330 away from the dotted through hole and away from the face paper, retracting back into the second through hole 211. Finally, the buffer elastic element 220 resets, and the pressure plate 210 moves away from the carrier plate 400. In this way, when the cutter 330 comes off the face paper 21, the face paper 21 is pressed by the pressure plate 210, so the cutter 330 will not stick to the face paper 21, avoiding damage to the face paper 21 during the punching process. In this way, after the long strip of face paper 21 has been fed forward a certain distance, the above punching action is repeated to form dotted slits on the paper bag to form a honeycomb bag. In one embodiment, both the buffer elastic element 220 and the punching elastic element 320 are helical springs.

[0036] like Figure 1 As shown, in one embodiment, a plurality of spaced guide posts 500 are provided on the substrate 100, and each guide post 500 passes through the pressure plate 210 and the punching plate 310.

[0037] In this way, both the pressure plate 210 and the punching plate 310 can slide up and down along the axial direction of the guide post 500, so that the cutter 330 can accurately cut a dotted slit on the face paper 21.

[0038] In one embodiment, multiple buffer elastic elements 220 are provided, and each buffer elastic element 220 is respectively sleeved on each guide post 500. Multiple punching elastic elements 320 are provided, and each punching elastic element 320 is respectively sleeved on each guide post 500.

[0039] It should be noted that, for example, four guide posts 500 are provided, so four buffer elastic elements 220 and four punching elastic elements 320 are provided respectively, to ensure that the pressure plate 210 and the punching plate 310 can slide stably along the axial direction of the guide posts 500 to approach or move away from the load plate 400.

[0040] like Figure 3 As shown, in one embodiment, the dashed via includes a plurality of first vias 411, each of the first vias 411 being equidistantly distributed along a straight line. Thus, the two dashed vias are distributed at intervals, that is, the plurality of first vias 411 in the two rows are staggered.

[0041] like Figure 3 As shown, in one embodiment, a clearance groove 110 is provided on the substrate 100, and a clearance hole 120 is provided on the inner bottom wall of the clearance groove 110. The material carrier plate 400 is detachably disposed in the clearance groove 110.

[0042] It should be noted that since the length and distance of the dotted slits in the honeycomb bag may vary depending on actual needs, the carrier plate 400 is designed as a detachable installation structure. To ensure that the surface of the carrier plate 400 is flush with the surface of the substrate 100, a clearance groove 110 is provided on the substrate 100, allowing the carrier plate 400 to be housed within it. When the pressure plate 210 descends, it can press the face paper 21 against the surface of the carrier plate 400. Furthermore, clearance holes 120 are provided on the bottom wall of the clearance groove 110 to allow clearance for the cutter 330, preventing the cutter 330 from directly colliding with the substrate 100.

[0043] like Figure 2 As shown, in one embodiment, a fixing lug 340 is provided on the top of the punching plate 310. This facilitates the connection of a drive source such as a motor to the punching plate 310, enabling the drive source to drive the punching plate 310 to move closer to or further away from the substrate 100.

[0044] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
