Manufacturing method of three-dimensional box gluing machine

The existing box pasting process is to fold the original paperboard of a die-cut box into two layers without hollow in the box gluing machine for gluing. After applying the glue, the glue shall be pressed dry in the press at the back end. The existing box gluing machine applies pressure to the gluing part after pasting the box, but the three-dimensional box cannot be heavily pressed in the whole box pasting production process, otherwise the box will be deformed. Therefore, the existing box gluing machine can only be suitable for installing the above process to produce flat boxes, not for pasting three-dimensional boxes. At present, the three-dimensional boxes are made by hand. The special mold is used to manually fold the original paperboard to form a three-dimensional shape, and then the hot-melt glue gun is used for manual gluing. This production method is inefficient, can not meet the customer’s delivery date, and the quality of manual paste box is unstable, which is easy to produce quality problems such as glue opening, glue overflow and less glue.

Content of utility model

In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a three-dimensional box gluing machine with high efficiency and ensuring product quality. In order to overcome the shortcomings of the prior art, the technical scheme adopted by the utility model is a three-dimensional box gluing machine, which is used to fold the pre pressed folded paperboard into a three-dimensional box shape and paste it tightly. The three-dimensional box gluing machine comprises a water feeding belt for transmitting workpieces, a shaper arranged upstream of the water feeding belt, and a box pressing device arranged downstream of the water feeding belt, The forming device comprises a flanging part arranged on the side of the water feeding belt and a suspension core plate arranged parallel to the upper side of the water feeding belt. The flanging part has a horizontal I-shaped connector end, a forming end bent towards the middle of the water feeding belt, and a turnover part connecting the connector end and the forming end. A part of the suspension core plate is embedded in the forming end with a gap.Another part of the hanging core plate is embedded in the turnover part with a gap.As an improvement of the above solution, the thickness of the suspension core board is equal to or less than the thickness of the inner cavity of the three-dimensional box. As an improvement of the above solution, a set of the shaper and the box press are provided on both sides of the flowing water conveyor belt. As an improvement of the above solution, the box press includes a press box body fixedly hung on the upper side of the flowing water conveyor belt, and a free end connected to the press box body as an integral part away from the introduction part of the flowing water conveyor belt. As an improvement of the above solution, the introduction part is arc-shaped. As an improvement of the above solution, the surface of the flange piece is covered with a flexible surface layer.The beneficial effect of the utility model is that by setting a shaper upstream of the water feeding belt, the hanging core plate of the shaper is used as the internal support, and the folding is carried out in combination with the flanging part on the side. In the process of moving along with the assembly line, the folding of the three-dimensional box body is realized under the action of the lateral folding force of the turnover part of the flanging part, and the ears on both sides are folded to form a hollow state. Then press the free edge of the ear under the action of the downstream box press, then apply hot melt adhesive, turn the front plate of the three-dimensional box through the pull hook, and then gently press it with a belt to complete the production of the three-dimensional box, so that the three-dimensional box can be automatically produced on the three-dimensional box gluing machine while ensuring the hollow, improve the efficiency, ensure the quality of the box, and ensure the consistency and quality stability of the box.
