Description

Technical Field

[0001] The utility model relates to the technical field of packaging box production, in particular to an automatic packaging box production line. Background Art

[0002] At present, when producing packaging boxes, foam particles are usually filled into the mold in the molding machine, and then high-temperature steam is filled for heating and pressurization. After molding, the operator takes the molded packaging box out of the mold and places it on the transfer vehicle on the side of the molding machine. When a certain number of packaging boxes are placed on the transfer vehicle, the operator transports the packaging box to the drying room for drying.

[0003] The above production process has the following technical defects: the operators transfer the packaging boxes by transfer vehicles, which is a heavy workload and low production efficiency; at the same time, the packaging boxes are stored in the production workshop for too long and cannot be dried in time, which makes the outer surface flatness of the packaging boxes worse. Even if the packaging boxes are dried in the drying room, it is difficult to restore the relatively flat state, which seriously affects the production quality of the packaging boxes. This is the deficiency of the existing technology. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide an automated packaging box production line in view of the shortcomings of the prior art. The packaging boxes manufactured by the molding machine are ejected from the mold by the ejection device and fall onto the inclined plate, and slide onto the conveyor belt through the inclined plate. The conveyor belt directly transports the packaging boxes to the door of the drying room in a timely manner. The operator takes the foam box off the conveyor belt and puts it into the drying room for drying, which effectively avoids the phenomenon that the flatness of the packaging box deteriorates due to long-term lack of drying.

[0005] The present scheme is realized through the following technical measures: an automated packaging box production line, comprising a plurality of molding machines arranged in sequence in a front-to-back direction, the molding machines being fixedly mounted on a support frame, an inclined plate being fixedly mounted on the support frame, the inclined plate being disposed below the molding machines, a conveyor belt being disposed on one side of the lower end of the inclined plate, the conveyor belt being used to convey the packaging boxes produced by the molding machines to the door of a drying chamber, the conveyor belt being disposed below the molding machines, the molding machines being provided with an ejector device for ejecting the packaging boxes manufactured by the molding machines from the molds, the packaging boxes ejected by the ejector device falling onto the inclined plate.

[0006] Preferably, a baffle is fixedly provided on one side of the conveyor belt, and the inclined plate and the baffle are provided on the left and right sides of the conveyor belt.

[0007] Preferably, a plurality of forming machines share one conveyor belt.

[0008] Preferably, a counterweight block is provided on the molding machine, and the molding machine is fixed on the supporting frame via the counterweight block.

[0009] Preferably, the lower end of the inclined plate is fixedly connected to a reinforcement frame, and the reinforcement frame is fixedly connected to the support frame. At the front and rear ends of each molding machine, the inclined plate, the reinforcement frame and the support frame form a triangular structure.

[0010] Preferably, the molding machine includes a frame, a guide rod is fixedly provided on the frame, a fixed mold is fixedly provided on the guide rod, and the fixed mold is connected to a material hose; a movable mold that can slide left and right along the guide rod is provided on the right side of the fixed mold, and the movable mold is connected to a steam hose; when the movable mold is in the rightmost position, a gap is left between the fixed mold and the movable mold, and the inclined plate is arranged directly below the gap.

[0011] Preferably, the ejector device includes a movable plate arranged on the left side of the fixed mold and an ejector fixedly arranged on the movable plate, the movable plate can slide left and right along the guide rod, and the right end of the ejector can penetrate the fixed mold.

[0012] Compared with the prior art, the technical solution of the utility model has the following technical effects:

[0013] (1) The packaging box produced by the molding machine is ejected from the mold by the ejection device and falls onto the inclined plate, and then slides onto the conveyor belt through the inclined plate. The conveyor belt directly transports the packaging box to the door of the drying room in a timely manner. The operator takes the foam box off the conveyor belt and puts it into the drying room for drying, which effectively avoids the phenomenon that the packaging box has poor flatness due to long-term lack of drying. During this process, the operator needs to observe whether the packaging box can slide onto the conveyor belt well to ensure that the conveyor belt can transport the foam box normally. Sharing one conveyor belt with multiple molding machines can save costs and reduce floor space.

[0014] (2) A baffle is installed on the conveyor belt to effectively prevent the packaging box from slipping off the conveyor belt.

[0015] (3) The inclined plate is stably fixed on the support frame through a reinforcement frame.

[0016] (4) By driving the ejector rod in the left-right direction, the manufactured packaging box can be ejected from the fixed mold and placed on the inclined plate.

[0017] (5) The molding machine is stably fixed on the support frame by a counterweight.

[0018] It can be seen that compared with the prior art, the utility model has substantial characteristics and progress, and the beneficial effects of its implementation are also obvious. BRIEF DESCRIPTION OF THE DRAWINGS
