Honeycomb paper core forming device
Technical Field
The invention relates to the field of honeycomb paper core production, in particular to a honeycomb paper core forming device.
Background
The honeycomb paper core is manufactured according to a honeycomb structure in the natural world, and the honeycomb paper core has the characteristics of sound absorption and noise reduction, so that the honeycomb paper core is usually used as a sound insulation part, and a better sound insulation effect can be achieved.
In the process of honeycomb refill production, need adopt the multiunit transfer roller to convey the paper respectively and compound many papers together, need adopt multiunit rubber coating mechanism to carry out glue strip coating to each paper along the length direction of paper respectively before compound, later cut the paper in sections along the width direction of compound back paper to pull open the paper of compound and form single honeycomb refill. However, in the production method of the honeycomb paper core, multiple groups of conveying rollers and multiple groups of glue coating mechanisms are used, so that the purchase cost of an enterprise can be increased when equipment is purchased, and the development of the enterprise is not facilitated.
In addition, in the production process of the honeycomb paper core, in order to avoid the phenomenon that the later conveyed paper is pressed against the cutter to generate wrinkles when the cutter of the transverse cutting station cuts the paper, the common conveying mode is that when the cutter downwards cuts, the motor is suspended, so that the conveying roller is suspended to rotate and feed; when the cutting knife moves upwards, the motor is started, so that the conveying roller continues to feed; because the motor needs a certain time to start and accelerate, the instantaneity of moving and stopping the paper is poor, and the paper is still wrinkled.
In order to solve the problem, in a plurality of groups of conveying rollers adopted in the prior art, arc-shaped gluing strips protruding out of the roller surface are uniformly distributed on each group of conveying rollers, the gluing strips can convey paper and coat glue on the paper after contacting the paper, and the paper is conveyed to a cutting station for cutting after gluing and compounding; the circumference length between two rubber coating strips is the width of cutting the paper promptly under this kind of condition, and the transfer roller needs to be changed the transfer roller when the paper of different width need be cut to the width of cutting according to the paper promptly and customizes, not only inconvenient, influences production efficiency moreover, still leads to the cost-push.
