Technical Field

[0001] The utility model belongs to the technical field of paper box processing equipment, in particular to a slitting device for packaging box processing. Background Art

[0002] The slitting machine for packaging box processing is also called a paper slitting machine. It is used to slit the whole roll or sheet of raw materials into fixed lengths. Before preparing for slitting, in order to save time in taking the raw materials, a small amount of raw materials needs to be piled on the operating table, and then the single raw materials are fed into the roller for slitting to avoid waste caused by the wrong position of the raw materials during slitting. Therefore, when stacking the raw materials, they need to be stacked neatly on one side to facilitate the subsequent accurate slitting position. When arranging the stacked raw materials, manual sorting is generally used. During the sorting process, it is impossible to stack all the sides of the raw materials flat, and the sorting process wastes a lot of time, affecting work efficiency. Utility Model Content

The fixed baffle 7 is arranged on the right side of the operating table 6 and is fixed in position by bolts, and the movable baffle 8 is located on the left side of the fixed baffle 7 and is parallel to the fixed baffle 7. A base plate 9 is provided on the left side of the movable baffle 8 and is fixed to the operating table 6. The fixing method can be bolt connection. A cam base 10 is fixed on the right side of the base plate 9, which can be a fixing method of bolts or welding. The cam 11 is installed with the cam base 10 through the turning handle 12, and the turning handle 12 is fixed with the cam 11 to realize synchronous rotation. The base plate 9 is installed with the movable baffle 8 through two spring tubes 13 to realize the left and right movement of the movable baffle 8. The spring cylinder 13 includes an outer cylinder 14, an inner shaft 15, and a spring 16. The outer cylinder 14 is vertically fixed to the base plate 9, the inner shaft 15 is vertically fixed to the movable baffle 8, and the inner shaft 15 is connected to slide left and right inside the outer cylinder 14. The outer cylinder 14 is provided with a spring 16, and the inner shaft 15 is reset by the spring 16 to achieve the reset of the movable baffle 8. The back of the turning handle 12 is provided with a torsion spring 17, which is reset by the torsion spring 17. The turning handle 12 is located above the base plate 9 and is limited by the base plate 9, so that the turning handle 12 is in a horizontal position in a natural state. There is space between the turning handle 12 and the operating table 6, which is convenient for hand-holding and turning the turning handle 12.

[0028] During the specific implementation process, the raw materials of multiple packaging boxes are piled on the operating table 6 for cutting. The right side of the raw materials is placed close to the fixed baffle 7, and the handle 12 is held to rotate the handle 12 clockwise. The handle 12 drives the cam 11 to move the movable baffle 8 horizontally to the right. The inner shaft 15 in the spring tube 13 plays a guiding role. The movable baffle 8 pushes the raw materials with uneven sides to make the right side of the raw materials close to the fixed baffle 7, so that the left and right sides of the raw materials are consistent, which is convenient for the subsequent rolling cutter 5 to accurately cut the raw materials, saves manual sorting time, and improves work efficiency. The handle and movable baffle 8 are reset by the torsion spring 17 and the spring 16 respectively, which is convenient for next use.

[0029] Example 2

[0030] In order to meet the needs of packaging boxes of various sizes, improvements are made based on Example 1, such as Figure 6-8 As shown, in this embodiment, a slide groove 18 in the left and right directions is opened on the operating table 6, and a slider 19 is fixed to the bottom of the base plate 9. The slider 19 is slidably connected along the slide groove 18, and can adjust the base plate 9 and the movable baffle 8 to move left and right as a whole. A screw sleeve 20 is fixed to the bottom of the slider 19, and the screw rod 21 is installed between the two machine bases 1 under the operating table 6. The screw rod 21 is threadedly connected with the screw sleeve 20, and a rocker 22 is installed at the end of the screw rod 21, so that the movable baffle 8 can realize the self-locking function of the base plate 9 through the screw sleeve 20 and the screw 21 after the position is moved and adjusted, thereby ensuring the stable position of the base plate 9.

[0031] During the specific implementation process, the rotating wheel 22 causes the screw 21 to drive the screw sleeve 20 and the base plate 9 to move horizontally to increase or decrease the distance between the movable baffle 8 and the fixed baffle 7, so that the movable baffle 8 maintains a certain space with the raw material, which is convenient for the placement of the raw materials and the pushing and sorting of the raw materials by the movable baffle 8, thereby realizing the function of sorting the raw materials of packaging boxes of various sizes.

[0032] Example 3

[0033] In order to reduce the resistance and scratching of the movable baffle 8 during the movement, the embodiment 2 is improved, such as Fig. 9 As shown, in this embodiment, fixed shafts 23 are respectively fixed on the front and rear sides of the movable baffle 8, and rollers 24 are installed on the fixed shafts 23. A gap is left between the movable baffle 8 and the operating table 6, and the height of the gap cannot be greater than the thickness of a single raw material.

[0034] During the specific implementation process, the movable baffle 8 does not directly contact the operating table 6 during movement, and moves on the operating table 6 through rollers, which reduces the friction of the movable baffle 8 during movement, makes it more labor-saving to use, and avoids scratching of the movable baffle 8 during movement.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
