[0044] The present invention is further explained and illustrated by specific implementation modes below. It should be understood that the purpose of the following implementation modes is to make the technical solution of the present invention clearer and easier to understand, and does not limit the protection scope of the claims.

[0045] The molding structure described in the present invention includes a main body 10; the main body 10 is at least partially configured as a contact surface 20; the contact surface 20 includes a first area 30 where glue can be discharged, and a second area 40 where glue cannot be discharged; the first area 30 and the second area 40 cooperate in a manner that can construct a support body with a blank area.

[0046] Preferably, the first region 30 is configured to be integrally formed.

[0047] Preferably, the first region 30 is configured in a ring shape.

[0048] Preferably, the first location 30 is composed of a plurality of sub-parts 31 , at least some of the sub-parts 31 being arranged to be spaced apart by the second location 40 ; and the plurality of sub-parts being spaced apart from each other constitute the first location 30 .

[0049] The molding mechanism described in the present invention includes a driving structure 50 and a plurality of the above-mentioned molding structures; the plurality of molding structures are all arranged on the driving structure 50 so as to follow the movement of the driving structure 50, and the bodies 10 of the plurality of molding structures have the same or different heights.

[0050] Preferably, the driving structure 50 is configured as a roller shaft 51 , and the molding structure is disposed on the circumference of the roller shaft 51 .

[0051] Preferably, the driving structure 50 includes a moving part 52 and a fixing part 53 which are telescopically matched with each other, and the molding structure is connected to the moving part 52 .

[0052] Preferably, the driving structure 50 is configured as an arc-shaped plate 54 , and the forming structure is disposed on an outer curved surface of the arc-shaped plate 54 .

[0053] The present invention provides an environmentally friendly packaging bag, comprising a bag body 60 , on which a support body 70 for buffering is disposed, and the shape and size of the support body 70 are determined by the structure of the first section 30 .

[0054] The invention also provides an application of the molding structure in producing environmentally friendly packaging bags.

[0055] The present invention will be further described below by means of specific examples.

[0056] Example 1

[0057] A molding structure in this embodiment, such as Figure 1-3 As shown, it includes a roller 51 and a glue coating head (a specific structure of the molding structure body 10); the glue coating head is arranged on the peripheral surface of the roller 51. The glue coating method is: the roller 51 rolls on the surface of the object to be glued (such as the packaging bag body 60), at this time, the glue on the glue coating head contacts and adheres to the surface of the object, and the glue coating is completed.

[0058] In addition, the purpose of setting the roller 51 is to drive the glue coating head so that the glue coating head can both contact with and separate from the surface of the object to be coated with glue, and feed the glue to the surface of the object in a contact and separation manner.

[0059] So, in order to achieve this technical purpose of driving movement, Figure 4As shown, a retractable mechanism can also be used. That is, the retractable mechanism includes a moving part 52 and a fixed part 53, and a glue coating head is arranged on the moving part 52; the moving part 52 is extended and retracted to drive the glue coating head to approach or move away from the surface of the object to be coated with glue.

[0060] The driving structure of the roller 51 and the retractable mechanism is suitable for large-scale industrial production with large production volumes.

[0061] In order to achieve the above technical purpose of driving movement, Figure 5-6 As shown, the curved plate 54 can also be used as a structure to drive the glue coating head to move. For example, the glue coating head is set on the outer surface of the curved plate 54, and a gripping handle is provided on the inner side of the curved plate 54. In this way, as long as the surface of the curved plate 54 is set to match the size of the surface of the object to be coated with glue, the glue can be applied manually by hand-gripping and rolling, and the glue can be subsequently formed into a support body 70 through foaming or other molding processes. This technical solution is suitable for production and manufacturing in small factories with low mass production and low labor costs.

[0062] Specifically, in the above technical solution, the glue coating head can also adopt a conventional spraying structure or an extrusion glue dispensing structure, that is, in terms of the glue dispensing or supplying structure, the present invention does not make a design different from the prior art. The present invention is more about improving the structure of the contact surface 20.

[0063] The glue coating head in this embodiment can be configured as a circular body 10, the middle of the body 10 is a solid structure, and an annular accommodating cavity (i.e., the first area 30) is formed circumferentially near the outer edge, and the accommodating cavity is filled with glue. The annular accommodating cavity contacts the surface of the object to be coated with glue, and an annular accumulation of glue is formed on the surface of the object to be coated with glue; thereafter, the glue is formed by foaming or other molding processes, and the annular shape can be maintained. In this way, the colloid has a certain hollow structure (i.e., a blank area), which saves colloid materials and reduces costs on the basis of being able to meet the cushioning properties of the colloid such as compression resistance and rebound. It can also be understood that, compared with the prior art, using the same volume of glue, the colloid formed by the present application has higher performance parameters, such as better supporting force, easier rebound and other stronger cushioning properties.

[0064] In addition, the principle of setting the annular accommodating cavity in the above scheme is to improve the three-dimensional stacking structure of the rubber material so that the rubber material has a certain hollow space or interval space (i.e., blank area) after being stacked, thereby further saving materials on the basis of ensuring the strength of the colloid structure after molding. In order to achieve this technical purpose, the structure of the main body 10 can also be set as: a plurality of independently spaced accommodating cavities. This technical scheme can also realize that the rubber material can form a three-dimensional structure with a certain space interval when it is stacked; it can also further partition the annular accommodating cavity on the basis of the annular accommodating cavity, so as to further reduce the amount of rubber material. It is worth noting that if there are more partition areas, the strength requirements for the rubber material after molding are also higher; or, the method of reducing the height of the colloid after molding is adopted to ensure that the colloid after molding has sufficient buffering performance. The structure in terms of height will be described later in this embodiment.

[0065] In addition, in the above technical solution, if Figure 7-16 As shown, the outer edge shape of the body 10 has little influence on the technical purpose of saving materials, and can usually be circular, regular polygonal, or even irregular in shape.

[0066] In addition, in the above technical solution, the shape of the accommodating cavity itself, or the regional structure formed by the different number and arrangement of the accommodating cavities, has little effect on the technical purpose of saving materials. The accommodating cavity can usually be set into a continuous annular shape, or a gluing area composed of multiple spaced and independent accommodating cavities. The shape of the accommodating cavity itself can also be changed, such as Figure 7-16 As shown, it is set to a circular, polygonal, and irregular shape.

[0067] Specifically, Figure 7-11 As shown, the first region is constructed into an integral shape; Figure 12-15 As shown, the first location is constructed in the form of interval distribution; Fig.16 As shown, the first region is mostly constructed in an integral shape, and partially constructed in a spaced and distributed form.

[0068] Specifically, the first region connected into an integral shape can also be understood as having a plurality of continuous sub-portions, such as Figure 7 , 11 , 16, the parts divided by dotted lines are sub-parts, and at least some of the sub-parts are separated by the second location. It can be seen that, whether it is a first location of an integral shape or a first location of an interval form (that is, a first location composed of a plurality of sub-parts), the sub-parts are arranged in intervals, which is the working principle of the present application to construct a support body with a blank location. Other structures derived from the rules revealed by this principle that can achieve the technical purpose can all be adopted.

[0069] In addition, the heights of the main bodies 10 of the multiple molding structures can be set to be the same, so that the same height of glue can be piled up on the surface of the object to be coated with glue. After foaming or other molding processes, the glue forms a colloid of the same height, which is used to play a cushioning role on the packaging bag; the heights of the multiple main bodies 10 can also be set to non-equal heights, such as a structure with gradually changing heights that is short at both ends and high in the middle. In this way, the stacking heights of glue at different positions can be better arranged according to the structural characteristics of the packaging bag (because the edge positions of the packaging bag need to be joined, and the position that mainly plays a cushioning role is the middle part), which can further save materials.

[0070] In addition, in order to make it easier to understand the technical solution and design concept of the present application, this embodiment provides an application scenario of the present application, such as Figure 17-18 As shown, that is, the support body 70 of the environmentally friendly packaging bag is formed by gluing (the support body 70 is formed by shaping the molded colloid).

[0071] This embodiment provides an environmentally friendly packaging bag, including a bag body 60 and a buffer structure. The buffer structure is arranged on the bag body 60, and plays a buffering and protective role such as shock resistance and pressure resistance in a deformable buffering manner. The buffer structure includes a plurality of support bodies 70, which are foamed and formed by foaming a foamable rubber material as the main substrate, and these support bodies 70 are arranged in a dot array manner; the support body 70 is mainly composed of starch granules, which are easy to degrade, especially in liquids such as water, and will not pollute the environment when discarded after use; arranging the support body 70 in a dot array manner can give full play to the buffering effect of the support body 70. Compared with the existing technology in which the buffer structure is set throughout the whole piece, the present invention not only has a reasonable force distribution and improves the buffering performance, but also saves materials and reduces costs.

[0072] Specifically, the support body 70 is arranged in a manner of gradually increasing in height and then gradually decreasing in height from one end to the other end of the bag body 60 .

[0073] The advantage of this arrangement is that, considering that during actual use of the packaging bag, the middle position is the area that mainly plays a buffering role, so the support body 70 is set at a higher height; at the two end positions, the bag body 60 itself needs to be bent, leaving less space, and it is not the position that mainly plays a buffering role, so the support body 70 is set at a lower height.

[0074] More specifically, the height difference between the multiple support bodies 70 should not be too large. Too large a height difference can easily cause the bag body 60 to be damaged by force, so the maximum height difference of the support bodies 70 is within 10-15%.

[0075] More specifically, adjacent support bodies 70 are arranged in sequence at a ratio of 2% increase in height.

[0076] Specifically, the bag body 60 is a double-layer structure, a receiving space 61 is formed between the double-layer structure, and the buffer structure is disposed in the receiving space 61 .

[0077] The present invention is described by way of embodiments, but does not constitute a limitation to the present invention. With reference to the description of the present invention, other changes to the disclosed embodiments are easily conceivable to professionals in the field, and such changes should fall within the scope defined by the claims of the present invention.
