Problems solved by technology

[0002] Most of the existing honeycomb core automatic production lines are composed of paper racks, stretching machines, gluing machines, pressing machines, and cutting machines. The honeycomb paper cores produced by the above-mentioned Ministry of Industry usually need to be converted into industrial products. Hot press forming process, when the hot press process is carried out, due to the narrow air flow channels between the layers of the honeycomb core and the airtightness of the honeycomb paper itself, it is difficult to quickly discharge the hot and humid gas, which will cause local foaming and The generation of quality problems such as bonding and detachment between paper cores affects the qualified rate of products

Embodiment Construction

[0010] The present invention as figure 1 , figure 2 As shown, a punching mechanism for a honeycomb paper core automatic production line, the punching mechanism includes a frame 1, an upper pressing roller 2 and a lower pressing roller 3, and the upper and lower pressing rollers 2 and 3 are rotatably installed respectively On the frame 1, a paper feed channel 4 is arranged between the upper and lower pressing rollers 2, 3, and roller needles 31 are densely distributed on the surface of the lower pressing roller 3.

[0011] The above-mentioned roller needles 31 densely distributed on the roller surface of the lower pressure roller 3 are embedded in the roller surface of the lower pressure roller 3 in several spaced rings, and correspondingly, the roller surface of the upper pressure roller 2 corresponding to the roller needles 31 is provided with a relief groove 21 . On the frame 1 at both ends of the above-mentioned upper pressing roller 2, an air cylinder 5 connected with th...

Abstract

The invention relates to a perforating mechanism for automotic production line of honeycomb paper core, which comprises a frame, an upper compression roller and a lower compression roller; the upper and lower compression rollers can be arranged on the frame in a rotary way and a paper feeding channel is arranged between the upper compression roller and the lower compression roller; roll needles are densely distributed on the roller surface of the lower compression roller. Due to the perforating mechanism arranged on the automotive production line of the honeycomb core, air holes are uniformly distributed on the surface of each single piece of paper at the same time of compound forming of the honeycomb paper core; when the two-time hot pressing is carried out, the air with heat-moisture can be discharged from various air holes so as to effectively prevent defects of the foaming and unfirm bonding on the surface of the honeycomb paper core and ensure the quality of the finished product. In addition, the tension of the paper can be caused to be eliminated when the honeycomb paper core is stretched by arranging the air holes on the paper core, so as to ensure that the processed paper board is smoother.

Description

technical field [0001] The invention relates to honeycomb paperboard production equipment, in particular to a punching mechanism for an automatic production line of honeycomb paper cores. Background technique [0002] Most of the existing honeycomb core automatic production lines are composed of paper racks, stretching machines, gluing machines, pressing machines, and cutting machines. The honeycomb paper cores produced by the above-mentioned Ministry of Industry usually need to be converted into industrial products. Hot press forming process, when the hot press process is carried out, due to the narrow air flow channels between the layers of the honeycomb core and the airtightness of the honeycomb paper itself, it is difficult to quickly discharge the hot and humid gas, which will cause local foaming and The generation of quality problems such as bonding and detachment between paper cores affects the qualified rate of products.
