Description

Technical Field

[0001] The present invention relates to the technical field of cardboard die-cutting and forming, and in particular to a cardboard slotting and waste clearing device. The present invention also relates to a waste clearing method for removing paper scraps by using the cardboard slotting and waste clearing device. Background Art

[0002] At present, in the process of producing corrugated boxes, after the cardboard is printed and slotted, the paper scraps after slotting cannot be completely separated from the cardboard due to various reasons (such as fast speed, inappropriate gap between the slotting knife and the slot, quality problems of the cardboard itself, etc.), and the cut waste edges are easily stuck at the angle and not easy to fall off, resulting in poor waste removal. In addition, the excessive release force of unqualified die-cutting materials will also cause the waste discharge edges to break easily during die-cutting and waste discharge. Ordinary waste removal die-cutting machines are difficult to complete all waste removal work, and in most cases, manual waste removal is required, which not only causes a huge increase in labor costs, but also makes it difficult to prevent quality defects in printed products caused by manual waste removal.

[0003] The existing cardboard slotting and waste cleaning machines have high requirements for operators, who need to be familiar with and proficient in the equipment before they can operate it, which increases labor costs. In addition, during the cardboard slotting and waste cleaning process, the equipment will generate noise and dust due to the use of cutting knives, edge grinding and other operating procedures, which seriously affects the respiratory health of operators and needs to be adjusted and improved.

[0004] Therefore, the more advanced waste paper conveying system currently used in the industry sucks the paper strips and waste materials produced by the printing slotting machine and the flat die-cutting machine, makes them fall into the belt conveyor in the ditch, and then transports them to the shredding fan feed hopper, and after being cut by the shredding fan, they are transported to the cyclone paper air separator by the air duct, and the shredded paper falls into the fully automatic waste paper baler for packaging, and the dust-containing airflow enters the bag dust collector, and the clean air is discharged indoors or outdoors. However, the waste paper conveying system needs to be installed and set up in multiple process equipment, with high investment costs, which increases the difficulty of enterprise implementation.

In addition, a first driving part 5 is provided at one end of the paddle 3031, and the power output end of the first driving part 5 extends to drive the paddle 3031 to rotate, so that the other end of the paddle 3031 is away from the lower transmission part 302, and the elastic member 3032 elastically stores energy.

[0074] The cardboard slotting and waste clearing device of this embodiment drives the upper conveying part 301 and the lower conveying part 302 to convey at the same time by setting a driving mechanism 2, so that the cardboard moves along the conveying direction through the friction force of the upper conveying part 301 and the lower conveying part 302, and by setting a plurality of paddles 3031 for pressing paper scraps, and by setting elastic members 3032 with successively increasing pressing forces, the paper scraps passing through the paddles 3031 fall off after multiple pressings, which can not only avoid the situation in the prior art where the waste clearing is broken and the cleaning is not thorough, but also can make the paper scraps slowly fall off as a whole under the action of multiple increasing pressing forces, avoiding the situation of tearing and damage, and also avoiding the defect of broken paper scraps needing to be polished to produce dust.

[0078] As a preferred implementation mode, Figures 1 to 4 As shown, the driving mechanism 2 includes a second driving part 201 arranged on the frame 1, an upper transmission shaft 202 connected to the power output end of the second driving part 201 by belt transmission, a driving assembly 203 connected to the end of the upper transmission shaft 202 away from the second driving part 201, and a lower transmission shaft 204 connected to the driving assembly 203 and rotating simultaneously with the upper transmission shaft 202.

[0097] Step 2: The upper transmission part 301 and the lower transmission part 302 are started by the driving mechanism 2, and the paperboard is driven to be transmitted accordingly;

[0098] Step 3: After the cardboard has been transported for a preset distance, the waste clearing part 303 at the front end has completely passed through the paper scraps, and the first driving part 5 corresponding to the waste clearing part 303 extends to drive the paddle 3031 away from the cardboard. When the cardboard passes through several waste clearing parts 303 in sequence, the first driving part 5 extends in sequence;

[0099] Step 4: After the cardboard has completely passed through the waste removal assembly 3, the first driving parts 5 are retracted simultaneously;

[0100] Step 5: Repeat steps 1 to 4.

[0101] The waste cleaning method described in this embodiment is provided with a plurality of waste cleaning parts 303. Under the power transmitted by the upper transmission part 301 and the lower transmission part 302, the cardboard is pressed by the plurality of waste cleaning parts 303 in sequence, so that the paper scraps to be removed are gradually peeled off, thereby realizing the full-automatic waste cleaning demand. By gradually applying force to the paper scraps with indentations and peeling them off as a whole, the waste cleaning effect is ensured while avoiding dust caused by grinding.

[0102] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
