Description

Technical Field

[0001] The utility model relates to the technical field of carton wax coating equipment, in particular to a full-automatic wax coating machine for carton production. Background Art

[0002] In the prior art, in order to give corrugated paperboard excellent waterproof properties, a layer of paraffin wax is usually coated on its surface. The basic process of this process includes pouring liquid paraffin wax evenly on the surface of the corrugated paperboard, and then applying pressure with a rolling wheel so that the paraffin wax can fully penetrate and tightly combine with the corrugated paperboard, thereby forming a continuous and complete waterproof film on the surface of the paperboard. Although this method can achieve a waterproof effect to a certain extent, it has some obvious shortcomings in actual operation.

[0003] Specifically, the existing equipment for waxing corrugated cardboard often relies on a conveying mechanism that requires manual intervention before the rolling process. That is, each piece of corrugated cardboard needs to be placed in a designated position by the operator one by one, waiting for the subsequent waxing process. This manual operation method not only increases the labor intensity of workers, but also significantly reduces the overall efficiency of the production line, especially when facing large-scale production needs, its limitations are more obvious.

[0036] Among them, the feeding mechanism 20 includes a bracket 21, a conveying roller 22, a roller driving device (not shown in the figure), a discharge baffle 23 and a baffle driving device 24. The discharge baffle 23 is hinged to the bracket 21 and a plurality of clearance grooves 231 are opened through its end surface. The conveying rollers 22 are arranged one by one corresponding to the clearance grooves 231 and are driven by the roller driving device.
