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. Biggest Factor in Efficiency Improvement

Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] The invention relates to a device for opening holes in the sandwich layer of honeycomb paperboard, such as figure 2 As shown, it includes a pair of punching rollers 1 and paper guide rollers 2 that roll against each other. Both punching rollers 1 and paper guide rollers 2 are installed on the wallboard. It includes a steel roller body, the surface of which is covered with a hard rubber layer with a thickness of 5-10mm, and the same-side shaft ends of the perforated roller 1 and the paper guide roller 2 are respectively connected with a first gear 4 and a second gear 5 , the first gear 4 and the second gear 5 are equal in diameter and engaged, and the first gear 4 or the second gear 5 is connected with a motor with a reducer.

[0031] The structure of punching roller 1 comprises following three kinds:

[0032] The first type: the pun...

Abstract

The invention discloses a device for opening holes in a sandwich layer of honeycomb paperboard, which comprises a pair of counter-rolling punching rollers and paper guide rollers. Steel needles are provided on the surface of the punching rollers. The invention also discloses a method for opening a hole in a honeycomb paperboard sandwich layer opening device. The hole opening device for a honeycomb paperboard sandwich layer of the present invention is used to punch holes. Specifically, it is implemented according to the following steps: Step 1. Select the steel for punching Needle spacing and type, obtain the corresponding honeycomb cardboard sandwich layer opening device; Step 2, make the paper tape for making the honeycomb cardboard sandwich layer pass between the punching roller and the paper guide roller; Step 3, start the motor, make The second gear rotates, and the steel pin punches holes in the paper tape; step 4, turn off the power supply, and the production ends, and a honeycomb paperboard sandwich layer with a honeycomb wall surface opening structure is obtained. The invention improves the drying efficiency of the honeycomb paperboard by opening holes on the honeycomb wall surface of the sandwich layer of the honeycomb paperboard, and effectively improves the 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...
