Non-woven fabric roll packing box capable of being directly stacked

Abstract

The invention discloses a non-woven fabric roll packing box capable of being directly stacked. The packing box comprises a paper tube and end covers which are located at the two ends of the paper tube, wherein the paper tube comprises a square tube (1) and a circular tube (2) which is located inside the square tube (1), and the square tube (1) is adhered to the circular tube (2); each end cover comprises a square cover plate (3), and insertion pins (4) are arranged at the four corners, opposite to the paper tube, of each cover plate (3); each cover plate (3) is provided with vent holes (6), and the vent holes (6) are circumferentially distributed on the outer side of a hanging rod (5); and each insertion pin (4) is provided with a guide bevel (7), the side, opposite to the paper tube, of each cover plate is provided with a protrusion (8) which is embedded in the circular tube (2), and the height of each protrusion is smaller than 5 mm. The packing box used for packing the non-woven fabric rolls has the advantages that the damage probability of non-woven fabric rolls can be decreased, multiple packing boxes can be stacked without relying on external object blocking, and the occupiedsite area is small.

Description

technical field [0001] The invention belongs to the field of non-woven fabric transport packaging accessories, in particular to a non-woven roll packaging box that can be stacked directly. Background technique [0002] Manufacturers of non-woven fabrics generally roll non-woven fabrics on a tubular paper rod and sell them in rolls. The non-woven fabric rolls are first packed in boxes and then used for storage or transportation for sale. Such as figure 2 As shown, the existing packing box is composed of a round paper tube and an end cap. The non-woven fabric roll is placed in the round paper tube, and then an end cap is embedded in each of the two ends of the round paper tube and the end cap is fixed on the end cap with air nails. Round paper tube. In the process of stocking or transporting non-woven fabric rolls, if the stacking height of the non-woven fabric rolls is too high, the round paper tube may be crushed and deformed to squeeze the non-woven fabric rolls, which wi...
