What is a Heaven and Earth lid?

Diandi lid refers to a style of box. The lid of the carton is "heaven" and the bottom is "earth", so it is called "heaven and earth cover". Also known as Tiandi box, it is widely used in all kinds of hardcover gift boxes, shoe boxes, underwear boxes, shirt boxes, cell phone boxes and other types of boxes.

The processing technology of tian dian lid

With the enhancement of people's awareness of environmental protection, the global carton/carton packaging industry is developing rapidly, and the production capacity has increased greatly. As the folding carton has low processing cost, convenient storage and transportation, applicable to a variety of printing methods (lithographic/offset printing, gravure printing, letterpress/flexo printing, screen printing), easy to molding process (die-cutting and creasing, folding and gluing), suitable for automatic packaging (automatic completion of the opening - forming a package sealing process), easy to sell, display and recycling, and is conducive to environmental protection, etc., in particular, it is easy for the surface finishing (surface finishing), and it is also easy for the surface finishing (surface finishing). Through the surface finishing (varnishing, laminating, hot stamping, embossing), it is conducive to the publicity and promotion of goods, and improve the added value of products, and has been widely used in the packaging of cigarettes, alcohol, medicines, food, beverages, daily necessities, and handicrafts.

Traditional sky and earth cover carton (such as packaging and transportation with all kinds of sky and earth box, shoe boxes, shirt boxes, tonic boxes, etc.) in the completion of printing and cutting corners, but also need to rely on artificial or semi-automatic auxiliary equipment to carry out a nail machine nails mechanical processing process, that is, through the nail machine nails in order to complete the single corner of the lamination (four corners *** need to be pasted four times), or to carry out a process of gluing, this approach of the Production efficiency is low, increasing the raw materials and production costs, low unit labor efficiency, increasing the total cost, and at the same time, because of its nailing or gluing molding, the space occupied by the increase in a number of products are placed on the pallet cumulatively with each other, resulting in a great waste of space, restricting the logistics and warehousing economic efficiency.

In order to solve the problems of low productivity, high cost and large occupation of space in the existing technology, the emergence of carton molding machine solves this series of problems. Carton molding machine using PLC programmable controller, photoelectric tracking system, hydraulic pneumatic system, touch screen human-machine interface, the implementation of the automatic delivery of tissue, tissue gluing, automatic cardboard conveyor, cardboard molding paste the four corners, positioning and lamination, carton molding action in one go, the production efficiency compared with the traditional process of production increased by more than thirty times.

Production efficiency compared with traditional craft production increased by more than thirty times, and easy to mold, reducing the occupation of transportation and storage space, significantly improving the logistics and warehousing economic efficiency.
