Description

Technical Field

[0001] The present application relates to the technical field of cardboard gluing structures for folder gluers, and in particular to a cardboard gluing structure for folder gluers. Background Art

[0002] The box gluer is the equipment used in the last process of carton production. It is mainly used for gluing single-piece corrugated cardboard to meet the packaging needs of food, cotton and other products. It can glue the surface of the cardboard, squeeze the glue evenly through the extrusion equipment and apply it on the cardboard, so that the cardboard can produce an adhesive effect.

[0003] Through searching, Chinese patent announcement number CN211190750U discloses a glue pasting machine, including a glue storage box, a support frame, a connecting rod, a roller, a glue brush, a receiving plate, a transmission structure and a clamping structure. When in use, one side of the cardboard is clamped on the receiving plate by the clamping structure, and then the transmission structure is opened, and the connecting rod and the glue brush at the bottom of the glue storage box are driven by the transmission structure to slide along the support frame. The bottom of the connecting rod is rotatably connected to a roller, and the roller is in sliding contact with the cardboard. During the sliding process, the roller can flatten the cardboard and press it on the receiving plate, and the glue brush on the left side of the roller is used to glue the cardboard. Since the connecting rod is divided into two sections, the connecting rods at both ends are connected by a second spring, so that the height of the roller can be adjusted to adapt to cardboards of different thicknesses, and the receiving plate has a larger horizontal cross-section. Through the rolling clamping of the roller, it can be suitable for cardboards of various sizes and shapes, avoiding the problem of inconvenience in using traditional glue pasting machines.

[0004] With respect to the above-mentioned related technologies, the inventors found the following defects: the above-mentioned scheme solves the problem that the general specifications of the traditional gluing machine are determined, and its clamping structure for clamping the cardboard can only clamp cardboard of a specific size and thickness. When different cardboards are replaced, the clamping structure needs to be replaced or adjusted, which is very inconvenient to use. However, this device cannot perform position constraints according to cardboards of different sizes. The gluing position needs to be adjusted multiple times during gluing, and it cannot work continuously, resulting in an increase in workload and a deviation in the gluing position.
