Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of packaging equipment, in particular to a smearing device for a full-automatic packaging machine. BACKGROUND

[0002] The packaging machine is a processing device for forming a packaging box, and each component of the packaging box paperboard, such as a side plate, a bottom plate, and a top cover, needs to be folded and spliced. In order to firmly connect these parts together to form a stable three-dimensional structure, a smearing device is needed to smear an appropriate amount of glue on the folded and butted position of the packaging box paperboard to achieve stable bonding and ensure that the packaging box can be firmly bonded.

[0003] A glue smearing device for packaging carton production is disclosed in Chinese Patent No. CN222358729, which includes a workbench and a glue barrel arranged on the top of the workbench. The inside of the glue barrel is provided with a stirring mechanism, which includes a first motor fixed on the top of the glue barrel. The output end of the first motor is fixedly connected with a rotating shaft, and the outer side of the rotating shaft is fixedly connected with stirring blades. The bottom end of the rotating shaft is rotatably connected with a bearing, and the bottom of the bearing is fixed to the inner wall of the glue barrel. The outer side of the rotating shaft is fixedly connected with an upper horizontal plate, and the outer side of the upper horizontal plate is fixedly connected with a vertical plate. The bottom of the vertical plate is fixedly connected with a lower horizontal plate, and the inner wall of the lower horizontal plate is fixedly connected with the outer side of the rotating shaft. The outer sides of the vertical plate and the lower horizontal plate are both fixedly connected with brushes. This glue smearing device solves the problem that the glue will solidify into lumps if it cannot be stirred at all times during use due to its certain stickiness, thereby affecting the glue smearing effect of the carton.

[0004] However, during the glue smearing process, the paperboard on the surface of the workbench may be slightly offset due to mechanical vibration or manual error touch, and the offset of the paperboard will cause the glue to be unable to be evenly coated on the glue smearing area of the paperboard, thereby reducing the glue smearing quality of the paperboard and affecting the bonding effect of the paperboard, which is obviously insufficient. Practical new type content

[0005] In order to improve the glue smearing quality of the paperboard, the present application provides a smearing device for a full-automatic packaging machine.

After starting the suction pump, the suction pump forms a negative pressure in the negative pressure cavity and the suction holes through the suction pipe, and the paperboard is fixed in the vertical direction under the action of the atmospheric pressure difference.
