Description

Technical Field

[0001] The present invention relates to the field of packaging equipment, and particularly to a cardboard feeding device used on a carton forming and packaging machine. Background Art

[0002] Currently, the most common packaging method in domestic and foreign packaging is carton and paper box packaging. There are two main reasons. Firstly, paper materials are generally easy to obtain, with a wide variety of types, complete specifications, and convenient processing. Secondly, cartons and paper boxes are easy to destroy, recyclable, have the advantages of buffering, shock absorption, protecting products, low cost, and easy processing. Moreover, cartons and paper boxes are a type of green packaging material. With the increasing emphasis on environmental protection today, carton packaging is more and more favored by people and has good prospects. Due to the increasing market demand, there are an endless stream of carton packaging machines on the market. When using a carton packaging machine, a cardboard feeding device is required to separate the cardboard into individual pieces and supply them to the carton packaging machine for use. Patent Application No.: CN202221779603.2 discloses a cardboard feeding device for carton production, including a feeding device body. The feeding device body includes a fixing component. The fixing component includes a bracket and a bottom plate. A conveying component is installed inside the bracket. The conveying component includes a rotating roller and a belt. A feeding component is installed on the top of the bottom plate. The feeding component includes a pushing plate and a card box. The cardboard is evenly stacked in the card box, and the bottommost cardboard is pushed out for use by the pushing plate. However, after the cardboard is stacked in such a feeding device, the weight above the bottommost cardboard all acts on the bottommost cardboard. When the bottommost cardboard is pushed by the pushing plate, friction occurs between the bottom of the bottommost cardboard and the bottom plate, and between the top of the bottommost cardboard and the upper cardboard, which easily causes wear on both sides of the cardboard.

[0003] The present invention is studied and proposed in view of the deficiencies of the prior art. Summary of the Invention

[0004] The object of the present invention is to overcome the above-mentioned deficiencies of the prior art and provide a cardboard feeding device used on a carton forming and packaging machine.

[0005] The present invention can be realized through the following technical solutions:

[0006] The present invention discloses a cardboard loading device used on a cardboard box forming and packaging machine, which includes a frame. An air suction box device is arranged on the frame. The air suction box device includes multiple air suction box belts arranged on the frame. An air suction box slide bar is further fixed on the frame above the air suction box belts. An air suction box slide plate is arranged on the air suction box slide bar. An air suction box push plate is fixed on the air suction box slide plate. The air suction box push plate is arranged on the air suction box belt. An air suction box rotating rod is further arranged on the frame. The air suction box rotating rod is driven to rotate by an air suction box cylinder. An air suction box inclined plate is obliquely fixed on the frame at the end of the air suction box belt. A support plate is further fixed on the frame below the air suction box inclined plate. An air suction box motor is fixed on the frame. An air suction box turntable is fixed at the output end of the air suction box motor. An air suction box positioning shaft is fixed on the air suction box turntable. An air suction box rotating shaft is further fixed on the frame. An air suction box swing arm rotatably connected to the air suction box rotating shaft is arranged on the air suction box rotating shaft. An air suction box suction cup is fixed at one end of the air suction box swing arm. An air suction box pull rod is arranged at the other end of the air suction box swing arm. One end of the air suction box pull rod is rotatably connected to the air suction box swing arm, and the other end of the air suction box pull rod is rotatably connected to the air suction box positioning shaft. Stack the cardboard on the air suction box belt. After the air suction box cylinder extends and then retracts, since the air suction box disc is fixed to the air suction box rotating rod through a one-way bearing, when the air suction box cylinder extends and then retracts, the air suction box belt rotates, and the air suction box push plate pushes the cardboard forward. When the outermost cardboard reaches the position of the air suction box inclined plate, it leans against the air suction box inclined plate, and after the bottom of the cardboard is separated from the air suction box belt, it slides onto the inclined support plate. The air suction box motor is started, and the air suction box motor drives the air suction box turntable to rotate. The air suction box positioning shaft on the air suction box turntable drives the air suction box swing arm to swing around the air suction box rotating shaft through the air suction box pull rod. After the air suction box suction cup swings to the position of the cardboard, the air suction box suction cup sucks the cardboard and pulls the cardboard to a specified position to separate the cardboard into individual pieces. This device can separate the cardboard into individual pieces and transport them to a specified position. When the outermost cardboard moves, the weight of other cardboards does not act on the outermost cardboard, and this device will not cause wear to the cardboard.

[0007] Preferably, an air suction box push rod is arranged at the end of the piston rod of the air suction box cylinder. An air suction box disc is fixed at the end of the air suction box push rod. A one-way bearing is fixed at the end of the air suction box rotating rod, and the one-way bearing is fixed on the air suction box disc. The rotation of the air suction box rotating rod is realized through the cooperation of the one-way bearing and the air suction box cylinder, without using a motor, which reduces the product cost.

[0008] The present invention has the following advantages compared with the existing technology:

[0009] This device can separate the cardboard into individual pieces and transport them to a specified position. When the outermost cardboard moves, the weight of other cardboards does not act on the outermost cardboard, and this device will not cause wear to the cardboard. Description of the Drawings
