A box preforming mechanism for a box forming machine

Abstract

This utility model discloses a box pre-forming mechanism for a box forming machine, including a paper stacker (3). A pre-folding component and an adsorption component are arranged below the paper stacker (3). The key feature is that a side positioning plate (2) is provided corresponding to the pre-folding component. The side positioning plate (2) is connected to a movable drive component. When the adsorption component drives the cardboard of the paper stacker (3) to descend and bend through the pre-folding component, the movable drive component drives the side positioning plate (2) to move to abut against the side of the bent pre-formed box. This utility model has a simple structure and reasonable design, enabling the pre-forming of boxes and ensuring that the box maintains a stable shape after pre-forming before being fed into the subsequent forming station.

Description

Technical Field

[0001] This utility model relates to packaging equipment, specifically to a box preforming mechanism for a box forming machine. Background Technology

[0002] A box forming machine is a specialized piece of equipment used for the automatic forming of packaging boxes. Traditional box forming machines work by feeding cardboard to the forming assembly, where it is then squeezed downwards by a mold. As the cardboard is squeezed downwards, it enters the forming mold and is formed into a box. This type of forming assembly performs all the forming work in a single downward squeeze, resulting in a complex structure and high requirements for the operation of each forming component. Consequently, the forming quality and yield rate need improvement. Utility Model Content

[0003] In view of the deficiencies in the prior art, the technical problem to be solved by this utility model is to provide a box preforming mechanism for a box forming machine to solve the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A box pre-forming mechanism for a box forming machine includes a paper stacker, with a pre-folding component and an adsorption component disposed below the paper stacker. The mechanism is characterized by a side positioning plate corresponding to the pre-folding component, the side positioning plate being connected to a movable drive component. When the adsorption component drives the paperboard of the paper stacker to descend and bends it through the pre-folding component, the movable drive component drives the side positioning plate to move until it abuts against the side of the bent pre-formed box.

[0006] The pre-folding component includes a pre-folding block arranged along the movement path of the adsorption component. The pre-folding block can contact the cardboard and squeeze the cardboard to bend it.

[0007] The top of the pre-folded block is provided with a slope.

[0008] The pre-folded blocks are arranged at the four corners.

[0009] The adsorption assembly includes a nozzle holder on which a nozzle is mounted, and the nozzle holder is connected to a lifting drive assembly.

[0010] The active drive assembly includes a first cylinder, the cylinder body of which is mounted on the frame, and the piston rod of the first cylinder is connected to a side positioning plate.

[0011] The box preforming mechanism of a box forming machine described above can drive the cardboard to descend through an adsorption component and cooperate with a pre-folding component during the descent to achieve the first preforming of the box. After preforming, the shape of the box is positioned by a side positioning plate, so that the box can be stably conveyed to the next forming station after preforming. This simplifies the structure of subsequent forming components and forming processes, effectively improves the efficiency of box forming, and ensures the quality of box forming.

[0012] The present invention includes the following figures:

[0014] Figure 2 for Figure 1 Bottom-view perspective. Detailed Implementation

[0015] As shown in the figure, this utility model discloses a box pre-forming mechanism for a box forming machine, including a paper stacker 3. A pre-folding component and an adsorption component are arranged below the paper stacker 3. A side positioning plate 2 is provided corresponding to the pre-folding component and is connected to a movable drive component. When the adsorption component drives the cardboard of the paper stacker 3 to descend and bends it through the pre-folding component, the movable drive component drives the side positioning plate 2 to move until it abuts against the side of the bent pre-formed box. Specifically, the movable drive component includes a first cylinder 1, the cylinder body of which is mounted on the machine frame, and the piston rod of the first cylinder 1 is connected to the side positioning plate 2. Of course, in addition to the above structure, the movable drive component can also use common drive structures such as linear motors, rack and pinion structures, synchronous belt structures, lead screw structures, and cam structures to drive the side positioning plate 2.

[0016] In this embodiment, the pre-folding component includes a pre-folding block 4 positioned along the movement path of the adsorption component. The pre-folding block 4 can contact and compress the cardboard to bend it. The top of the pre-folding block 4 is provided with a slope 5. By providing the slope 5, the movement of the cardboard during the bending process in contact with the pre-folding block 4 can be smoother. Furthermore, the pre-folding block 4 is arranged at four corners, allowing it to contact and compress the four corners of the cardboard, ensuring the stability of the cardboard bending.

[0017] Furthermore, the adsorption assembly includes a nozzle holder 6, on which a nozzle 7 is mounted. The nozzle holder 6 is connected to a lifting drive assembly, which is a second cylinder 8. The piston rod of the second cylinder 8 is connected to the nozzle holder 6. By controlling the movement of the second cylinder 8, the nozzle holder 6 can be raised or lowered. Of course, in addition to cylinders, the lifting drive assembly can also use common drive structures on the market such as linear motors, rack and pinion structures, synchronous belt structures, lead screw structures, and cam structures to drive the nozzle holder 6 to rise and fall.

[0018] The working principle of this utility model is as follows: The suction nozzle frame 6 rises first, sucks up the cardboard at the bottom of the stacking paper frame 3, and drives the cardboard to fall. During the descent, the cardboard will come into contact with the pre-folding block 4, causing the cardboard to bend and form. When the stacking paper frame 3 drives the cardboard to the position, the active drive component will control the side positioning plate 2 to move, so that the side positioning plate 2 abuts against the side of the pre-formed paper box, so that the paper box will not deform during the backward conveying process.

[0019] This structure of the present invention can drive the cardboard to descend through the adsorption component and cooperate with the pre-folding component during the descent to achieve the first pre-forming of the cardboard box. After pre-forming, the shape of the cardboard box is positioned by the side positioning plate, so that the cardboard box can be stably conveyed to the next forming station after pre-forming. This can simplify the structure of the subsequent forming components and forming process, effectively improve the efficiency of cardboard box forming, and ensure the quality of cardboard box forming.
