Description

Technical Field

[0001] The utility model relates to the field of corrugated paperboard production, in particular to a paper loading machine for loading corrugated paperboard. Background Art

[0002] The process flow of corrugated cardboard printing is to put the corrugated cardboard one by one into the printing assembly line. The corrugated cardboard moves to the downstream side along the transmission roller of the assembly line. The transmission roller of the printing assembly line is at a certain height from the factory floor. In order to facilitate placing multiple pieces of corrugated cardboard on the upstream side of the transmission roller of the assembly line, it is necessary to first place multiple pieces of corrugated cardboard vertically on the paper loader. The paper loader tilts upward to the upstream side of the transmission roller of the assembly line. The corrugated cardboard placed vertically on the paper loader is manually pushed down piece by piece to make it record to the starting end of the transmission roller of the assembly line and move downstream along the assembly line.

[0003] However, as the workers lay the corrugated cardboard down and flatten it, the distance between the corrugated cardboard placed upstream of the paper loader and the paper loader becomes farther and farther, and it becomes increasingly inconvenient for the workers to flatten the corrugated cardboard placed upstream and then place it at the starting end of the transmission roller of the assembly line, which increases the labor intensity of the workers and has shortcomings. At the same time, the traditional paper loader has poor stability and is time-consuming and labor-intensive during the process of conveying corrugated cardboard. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3As shown, a paper loading machine for corrugated paperboard loading comprises a bottom plate 1, a roller 2 is arranged at the bottom of the bottom plate 1, that is, the bottom plate 1 can slide on the paper loading machine track, an inclined stop frame 3 is fixed on the bottom plate 1, and multiple pieces of corrugated paperboard 10 can be vertically stacked on the stop frame 3, and multiple pulleys 4 are evenly arranged on the front and back sides of the bottom plate 1 close to the downstream side, and transmission belts 5 are wrapped around the multiple pulleys 4. When the corrugated paperboard 10 is vertically stacked, the bottom is placed on the transmission belt 5, and the surface of the transmission belt 5 is provided with anti-skid patterns 9, which can increase the friction between the corrugated paperboard 10 and the transmission belt 5, so that the corrugated paperboard 10 is not easy to tip over;

[0023] An electric push rod 7 and a plurality of brackets 6 are horizontally arranged at a position near the upstream side of the bottom plate 1. The electric push rod 7 is arranged on the bracket 6. The end of the transmission belt 5 near the baffle 3 is aligned with the connection position of the baffle 3 and the bottom plate 1. When the corrugated cardboard 10 is vertically stacked on the baffle 3, the bottom of the corrugated cardboard 10 just rests on the transmission belt 5, and the corrugated cardboard 10 moves and always rests on the transmission belt 5.

[0024] A push plate 8 is provided at one end of the piston rod of the electric push rod 7 close to the baffle frame 3. The angle between the baffle frame 3 and the upper surface of the bottom plate 1 below the electric push rod 7 is 70° to 85°. The electric push rod 7 is located at half the height of the baffle frame 3. The push plate 8 is located inside the baffle frame 3 and is consistent with the inclination angle of the baffle frame 3. When the electric push rod 7 is extended, the push plate 8 can push the corrugated cardboard 10 stacked on the baffle frame 3 toward the downstream side of the bottom plate 1.

[0025] In this embodiment, the electric push rod 7 is connected to an electric push rod motor, and the electric push rod motor is a servo motor, which is convenient for controlling the pushing speed of the electric push rod 7, thereby improving the transportation efficiency and stability of the corrugated cardboard box and reducing the labor intensity of manual labor.

[0026] In this embodiment, the angle between the gear frame 3 and the upper surface of the bottom plate 1 below the electric push rod 7 is preferably 75° or 80°, which is convenient for placing the corrugated cardboard and solves the problem that the corrugated cardboard placed far upstream of the existing feeding machine is inconvenient to place on the assembly line.

[0027] In this embodiment, the pulley 4 is located above the roller 2 .

[0028] In this embodiment, the bottom plate 1 is integrally cast.

[0029] In this embodiment, at least nine pulleys 4 are provided, and the interval between the centers of adjacent pulleys 4 is 11-13 cm.

[0030] In this embodiment, at least nine rollers 2 are provided, and the interval between the centers of adjacent rollers 2 is 20-25 cm.

[0031] Working principle: Multiple pieces of corrugated cardboard 10 are stacked obliquely on the retaining frame 3, the bottom edge of the corrugated cardboard 10 is placed on the transmission belt 5, the bottom plate 1 moves downstream to above the initial end of the printing assembly line transmission roller, and the worker stands at the work station to push the corrugated cardboard 10 down and place it flat on the initial end of the printing assembly line transmission roller. When the corrugated cardboard 10 is far away from the initial end of the printing assembly line transmission roller and is inconvenient to operate, the electric push rod 7 is used to push the corrugated cardboard 10 toward the downstream side, so that the worker can easily push all the corrugated cardboards 10 from the bottom plate 1 and place them flat on the initial end of the printing assembly line transmission roller, thereby reducing labor intensity.
