A kind of sticky lock into box lock and its carton into box method

Abstract

The invention relates to a lock catch stitching cardboard to carton and carton making method. The lock catch comprises a primary catch (1) and a secondary catch (2), wherein the primary catch (1) comprises screw-in structure (3), at least one locking nail (4) and baseplate (5); the screw-in structure (3) is on the baseplate (5) to hold the screw blade (6) of the secondary catch (2); the locking nail (4) is on the baseplate (5); the secondary catch (2) comprises a screw blade (6) and the baseplate (5); the screw blade (6) is on the baseplate (5) for the screw-in structure (3) of the primary catch (1), realizing the connection of the primary catch (1) and secondary catch (2). The method avoids the disadvantages of carton making of stapler or sticking, the issues of appearance, and damages and abrasion caused by carton making machines. The method provides a convenient making method to produce more solid cartons by the catches.

Description

technical field [0001] The invention relates to the field of cartons and packaging boxes, in particular to cartons and locks and fastening parts of the packaging boxes, and in particular to an adhesive lock lock and a carton forming method thereof. Background technique [0002] Carton packaging is widely used in various industries. It has the advantages of environmental protection, recyclability, light weight, foldable, low transportation cost, and beautiful printing. Compared with other main packaging types (plastic, wood), it has low cost, high production efficiency, and raw materials. adequate. Based on the above advantages, carton packaging will be irreplaceable in the next few decades. At present, white goods such as refrigerators, washing machines, cabinet air conditioners, household flooring and other industries in the world basically use cartons as outer packaging. [0003] At present, the carton industry generally uses two methods for carton boxing and high-effici...

AI Technical Summary

Problems solved by technology

[0004] (1) Nails: The flat wires used for nailing copper-plated or galvanized cartons are prone to rust and affect the product brand image; there are potential safety hazards for children after entering the family; the sharpness of the staples may scratch the exterior paint surface of the packaged products The current solution is to manually paste single-sided glue on the order part, but the improvement effect is not obvious, and there are obvious disadvantages such as unsightly, high cost, and very low efficiency. The implementation needs to be manually drilled into the box. Construction, operation is cumbersome

[0005] (2) Gluing box: only the surface paper of the corrugated board and the surface paper are adhered, and the interlacing and fixing of each layer of corrugated boards and sandwiches of the entire corrugated board cannot be realized. There is a risk of cracking at the mouth of the carton packaging, so the way of gluing the box is in large and medium-sized Cartons are rarely used in boxes. Even if they are used, there will be waste of adhesive tape or adhesive, which will not only cause pollution but also look ugly. The implementation needs to be manually drilled into the box for construction, and the operation is cumbersome

However, products based on the above technologies have not been promoted and used on a large scale so far, because they have fundamental design flaws and are not suitable for the field of cartons and packaging boxes, as follows:

[0008] (1) The connection method of the button barrel and the button nail is adopted, because the button barrel and the button nail are both cylindrical outer surfaces with smooth contours. After they are fixed to the carton, they cannot form a tight connection with the corrugated structure. During transportation or other vibrations It is easy to loosen in the state;

[0009] (2) The lock is formed by using meson + gusset plate and additionally setting the pot-shaped inner tooth meson. Its shape and material lead to extremely high mold opening cost and production cost, and the lock structure is used in the field of packaging boxes, which requires great compression Cost, so the above-mentioned design has the problems of complex structure and high cost;

[0010] (3) Both the bottom plate of the meson and the bottom plate of the pinch plate are designed with straight sides. During the transportation process after assembly, the friction between the packing boxes and the friction between the packing box and the ground will inevitably cause the pinch plate to be damaged. Collision thus falls off, and the meson in the box is no different from the original nail at this time, and the blade surface formed by the flat surface will still scratch the surface of the contents;

[0011] (4) The sharp tooth structure is set on the meson, which forms the blade surface at multiple angles. Combining the above problems (1) and (3), during the vibration or collision process, the blade surface will inevitably cut the carton or corrugated structure, causing the meson to fall off. ;

[0012] (5) The final buckle is buckled by the convex edge and the wall tube strip. It is difficult to loosen after one consolidation and cannot be reused, and the above-mentioned convex edge and wall tube strip are designed on the buckle tube and the buckle nail. And the cost of production is too high, and the inability to reuse leads to waste
