Abstract
Description
Technical Field
[0001] This invention relates to the field of packaging production and processing, and specifically to a method and apparatus for forming inner linings of packaging materials. Background Technology
[0002] In the conventional packaging and printing industry, especially in the packaging of electronic products, the inner lining structures vary greatly due to the different shapes and arrangements of the contents. These complex inner linings, from die-cut sheets of paper to the required shapes, are mostly formed by hand. During the hand-forming process, the different force applied by each person and at different times leads to significant differences in the forming angle. In addition, some areas require localized pressing after forming to ensure a tight fit, but due to worker fatigue, the pressure applied at different times varies, resulting in the risk of the inner lining coming unglued.
[0003] The standard production process for packaging linings includes die-cutting, grooving, pre-crease forming, adhesive application, corner folding, and shaping. However, while the pre-crease forming is done at a standard pressure and angle, shaping and corner folding are generally done manually or manually with jigs. This heavy manual involvement makes it difficult to guarantee the forming angle and maintain consistent pressure. Frequent manual exertion also easily wears down the fingers of workers, making prolonged operation impossible and causing serious harm to workers.
[0004] Therefore, it is necessary to provide a method and apparatus for forming packaging linings to solve the above problems. Summary of the Invention

[0063] Please see Figure 1 In this embodiment of the invention, a method and apparatus for forming a packaging liner includes:
[0064] S1: Packaging material die cutting, cutting the relevant packaging materials, cutting the sheet into shape, and pressing the creases of the relevant materials;
[0065] S2: Packaging material grooving, grooving and drilling operations are performed on the processed board material in the previous step to leave space for the board bonding and corners;
[0066] S3: Apply adhesive; apply adhesive to the area reserved in the previous step.
[0067] S4: Corner pressing: Based on the corner reserved when the packaging material is slotted, the corner is pushed out using a mold, and then pressed down using a mold to make the force of the folding angle the same.
[0068] S5: Packaging forming, completing the corner folding, pasting, trimming and inspection processes of the packaging material, and completing the production of a packaging material lining product.
[0069] As a preferred embodiment, in the corner pressing step, the relevant mold can be replaced according to the shape of the liner and the number of folding angles.
[0070] In this embodiment, during the S4 corner pressing step, some of the corners will stick to the adhesive in the S3 adhesive application process, while the other part will not stick to the adhesive. This needs to be checked in the S5 packaging and forming step.
[0071] In this embodiment, as Figure 2 In the S4 corner bending and pressing process, a die is used for corner bending and subsequent pressing operations. The die includes:
[0072] Fixed mold 1;
[0073] The moving mold 2 is connected to the fixed mold 1;
[0074] The assembly module 3 is arranged in multiple groups on the connection surface between the fixed mold 1 and the moving mold 2.
[0075] In this embodiment, as Figure 3 , 4 And 5, the moving mode 2 includes:
[0076] Moving shell 21;
[0077] The lower pressure layer 22 is arranged in two sets at intervals and symmetrically on one surface of the moving shell layer 21, and the lower pressure layer 22 is connected to the moving shell layer 21;
[0078] Contact surface 23 is arranged on the other side of the lower pressing layer 22 connecting to the moving shell layer 21, and multiple sets of the combined modules 3 are arranged at the four corners of the contact surface 23;
[0079] A pressing mechanism 24 is disposed between the contact surface 23 and the pressing layer 22, and the pressing mechanism 24 is located on the side closer to the contact surface 23;
[0080] The bearing surface 25 is located within the lower pressing layer 22 and below the lower pressing mechanism 24, and above the moving shell layer 21;
[0081] Multiple sets of alignment blocks 26 are symmetrically installed on one surface of the bearing surface 25, and are located on the same surface of the bearing surface 25 as the pressing mechanism 24;
[0082] Multiple cylinders 27 are installed on the lower pressure layer 22 and connected to the other side of the bearing surface 25 where the lower pressure mechanism 24 is installed.
[0083] It should be noted that the cylinder 27 is connected to the outside to provide power to the pressing mechanism 24. The contact surface 23 is located above the bearing surface 25, and the contact surface 23 has a hole, the shape of which is determined by the shape of the pressing mechanism 24. This ensures that in the natural state of the cylinder 27, the pressing mechanism 24 is entirely below the contact surface 23; and in the extended state of the cylinder 27, the pressing mechanism 24 can extend from the hole in the contact surface 23. The cylinder 27 is connected to the bearing surface 25, and the cylinder 27 pushes the bearing surface 25 to push the pressing mechanism 24 fixed on the bearing surface 25.
[0084] In this embodiment, as Figure 5 The lower pressure layer 22 includes:
[0085] The base plate 222 is connected to the moving shell layer 21;
[0086] Multiple sets of vertical plates 221 are arranged on the other side of the moving shell layer 21 that connects to the pressure plate 222, and are connected to the bearing surface 25;
[0087] Multiple sets of mounting holes 223 are formed on the lamination base plate 222, and the cylinder 27 is installed in the mounting holes 223.
[0088] In a preferred embodiment, the lamination base plate 222 is connected to the moving shell layer 21, and the mounting hole 223 is formed in the lamination base plate 222, that is, the mounting hole 223 does not pass through the moving shell layer 21.
[0089] In this embodiment, as Figure 5 The bearing surface 25 includes:
[0090] The support plate 252 is connected to the cylinder 27 on one side and to the pressing mechanism 24 on the other side;
[0091] The guide post 251 is installed in multiple sets on the lamination base plate 222 and passes through the bearing plate 252, located on the side of the lamination base plate 222 where the layer stand plate 221 is installed.
[0092] In a preferred embodiment, both the guide post 251 and the alignment block 26 serve to position the mold. Furthermore, the guide post 251 also ensures that when the cylinder 27 pushes the support plate 252, the support plate 252 moves horizontally as a whole, meaning that the movement speed at each position is the same.
[0093] In this embodiment, as Figure 7 The pressing mechanism 24 includes:
[0094] The connecting part 241 is arranged in multiple groups on the support plate 252 and connected to the support plate 252, located on the other side of the support plate 252 where the cylinder 27 is connected;
[0095] The pressing part 242 is located in the connecting part 241 and is spaced apart from the connecting part 241 and the supporting plate 252;
[0096] Spring 243 is installed between the pressing part 242 and the connecting part 241, and is fixedly connected to the pressing part 242 and the connecting part 241.
[0097] In a preferred embodiment, the connecting part 241 is fixed, that is, when the cylinder 27 pushes the support plate 252, the connecting part 241 moves with the support plate 252. However, when the mold is closed, the pressing part 242 will generate a force that naturally pushes towards the stationary mold due to the compression of the spring 243. After completion, when the mold is separated, the pressing part 242 will be reset due to the spring 243.
[0098] In this embodiment, as Figure 8 The fixed mold 1 includes:
[0099] Fixed shell 11;
[0100] The mounting layer 12 is arranged in two sets at intervals and symmetrically on one surface of the fixed shell layer 11, and the mounting layer 12 is connected to the fixed shell layer 11, and the mounting base plate 121 is provided on the connection surface between the mounting layer 12 and the fixed shell layer 11.
[0101] The corner bending mechanism 13 is arranged in the mounting layer 12 and connected to the mounting base plate 121.
[0102] In this embodiment, as Figure 9 The bending mechanism 13 includes:
[0103] The angled base 132 is connected to the mounting base 121;
[0104] An opening head 131 is arranged on the angled base 132, and the opening head 131 is located on the opposite side of the angled base 132 connecting the mounting base 121;
[0105] The positioning blocks 133 are arranged in multiple sets on the angled base 132 and are located on the same side of the angled base 132 and the opening head 131.
[0106] In a preferred embodiment, the positioning block 133 serves to align the cornering mechanism 13 and the pressing mechanism 24 during mold closing. The corner opening head 131 remains stationary, waiting for the pressing part 242 to approach the corner opening head 131 to complete the cornering work for the relevant product.
[0107] In this embodiment, as Figures 12-15 This describes the usage process of a packaging material lining mold.
[0108] In a preferred embodiment, the cylinder 27 pushes the connecting part 241 and the pressing part 242 downward, and the product 4 is placed above the corner opening head 131. When the mold is closed, the corner opening head 131 naturally protrudes due to the mold closing. After the product 4 is protruded by the corner opening head 131, the pressing part 242 contacts the product 4 to complete the corner pressing action of the product 4.
[0109] In this embodiment, as Figure 16 This is a schematic diagram of the packaging lining.
[0110] In a preferred embodiment, the product 4 includes a sheet 41 and an inner lining 42, and the folding mechanism 13 and the pressing mechanism 24 design the shape of the inner lining 42 accordingly.
[0111] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
