Honeycomb paperboard sandwich layer punching device and punching method thereof

Abstract

The invention discloses a honeycomb paperboard sandwich layer punching device. The honeycomb paperboard sandwich layer punching device comprises a punching roll and a paper guiding roll which can oppositely roll, wherein the surface of the punching roll is provided with steel needles. The invention further discloses a punching method of the honeycomb paperboard sandwich layer punching device. Whenthe honeycomb paperboard sandwich layer punching device is used for punching, the punching method is implemented specifically according to the following steps: step 1, selecting the interval and themodel number of the steel needles for the punching, and obtaining the corresponding honeycomb paperboard sandwich layer punching device; step 2, enabling a paper band used for manufacturing a honeycomb paperboard sandwich layer to pass through an interval between the punching roll and the paper guiding roll; step 3, starting a motor, enabling a second gear to rotate, and using the steel needles topunch the paper band; and step 4, turning off a power source, finishing production, and obtaining the honeycomb paperboard sandwich layer with a honeycomb wall surface punching structure. The honeycomb paperboard sandwich layer punching device and the use method thereby punch the honeycomb wall surface of the honeycomb paperboard sandwich layer, improves drying efficiency of a honeycomb paperboard, and effectively improves production efficiency of the honeycomb paperboard.

Description

technical field [0001] The invention belongs to the technical field of packaging engineering, and relates to a device for opening holes in a sandwich layer of honeycomb paperboard, and also relates to a method for opening holes in the device for opening holes in a sandwich layer of honeycomb paperboard. Background technique [0002] Honeycomb paperboard is a lightweight and high-strength composite material formed by bonding upper and lower face paper to a honeycomb-shaped paper core through an adhesive. It is a typical case of human bionics research and application. The specific structure of honeycomb paperboard is as follows: figure 1 As shown, it includes two sheets of face paper, and a core paper is set between the two sheets of face paper as a sandwich layer. Honeycomb paperboard has outstanding compressive and bending resistance, so it is widely used in packaging and structural molding. [0003] However, the widespread use of honeycomb paperboard has been facing huge o...

Problems solved by technology

At present, all honeycomb paperboard production lines cannot completely dry the moisture sealed in each airtight compartment. After off-line, the honeycomb paperboard must go through a long-term natural environment ventilation and drying process, so the drying problem is affecting the honeycomb paperboard production.
