Description

TECHNICAL FIELD

[0001] The utility model relates to the packaging printing technical field especially, relates to a paper edge trimming line dust collector and contain its paper cutter. BACKGROUND

[0002] In the packaging printing material industry, the paper powder and paper hair are required higher, and are required higher in the printing process, and the paper powder and paper hair can cause the serious harm to the printing, mainly including the following aspects:

[0003] 1. directly make the figure part suffer from different degrees of damage, under normal circumstances, when the rubber cylinder or printing plate separates from the paper surface in printing, the ink is evenly and completely transferred to the paper surface, and accurate and clear image is formed on the paper surface, if paper hair and paper powder occur, part of the ink not only fails to be transferred to the paper surface, but also sticks the substance on the paper surface to the rubber blanket or printing plate, if the sticking area is very small, then very small white point is generated in the image of the printed matter, if the sticking area is larger, the image part of the printed matter will appear white spot, which seriously affects the quality of the printed matter, and even causes waste product;

[0004] 2. form the ink pile, when the paper hair and paper powder occur, the fiber or material particles pulled from the paper surface will be mixed and adhered to the rubber blanket, and gradually accumulated to form the ink pile, when the ink pile begins to form, the roughness of the intermediate tone part in the image is first shown, which is due to the mixed fiber, pigment and ink, and the convex part is formed on the rubber blanket, which is caused by the poor transfer of the ink, the ink pile will hinder the transfer of the ink, so that the color of the image is not bright, the screen dot is thick, and the clarity is reduced, when the ink pile is serious, the irregular annular white spot is formed on the printed matter around the convex part, and even the plate jamming failure occurs;

[0005] 3. paste and jam the plate, cause the screen dot on the image to be not full and neat, and the figure and text to appear incomplete and various spots, in the offset printing process, if the larger material (coating block or fiber block) is peeled off from the paper surface, that is, the paper hair occurs, or other types of paper hair and paper powder form the ink pile, these larger impurities or accumulated materials will possibly go through three stages, first, stay in the image part of the rubber blanket, then, be transferred to the image part on the printing plate, and finally, be mixed into the ink supply system;

[0006] 4. annular spot, when the impurities on the rubber blanket are relatively thick, the ink around the impurities is affected and cannot be transferred, so that the annular spot is formed, if the impurities are thin, or have a certain thickness but can be extruded thin by the printing pressure, the annular spot will not be produced due to the influence of the elasticity of the rubber blanket, only when the impurities can maintain a certain thickness under the action of the printing pressure, the annular white spot will be produced on the image of the printing surface;

[0007] 5. Foreign matter, ring-shaped white spot is generally caused by foreign matter, the thicker the foreign matter, the larger the width of the ring, the larger the foreign matter, the larger the diameter of the ring, and a large enough foreign matter will also break the rubber blanket, in addition, when the transfer performance of the foreign matter to the ink is similar to that of the rubber blanket, the image part transferred by the foreign matter surface and other parts also differ little, but when the transfer performance of the foreign matter to the ink is quite different from that of the rubber blanket, the image part transferred by the foreign matter surface and other parts also differ greatly, non-ink-absorbing foreign matter will leave a white spot similar to the foreign matter surface on the printed surface, and the foreign matter remaining on the rubber blanket may be transferred to the paper surface during operation or to the printing plate, the foreign matter transferred to the paper surface will only form a foreign matter on the printed product without affecting subsequent printing, but if the foreign matter transferred to the printing plate is a material with high hydrophilicity, the foreign matter will absorb fountain solution rather than ink during printing, thereby producing a white spot, and the white spot produced by peeling off the non-paper surface on the printed product is generally this kind, and if the foreign matter transferred to the printing plate is a material with high lipophilicity, it will accept ink rather than fountain solution, at this time the printing result is the same as that of the foreign matter remaining on the rubber blanket, both of which produce ring-shaped white spots;

[0008] In addition, when the foreign matter formed by paper fluff and paper powder is mixed into the ink supply system or deposited in the ink fountain from the printing plate, the properties of the ink will deteriorate, the color will deteriorate, and the wear on the ink roller and the printing plate will be increased, and color impurity spots will appear on the printed surface, so paper fluff and paper powder are problems that cannot be ignored in the packaging printing industry. Currently, the industry generally uses cross-cut machines, spiral double-knife cutting machines, and stripping machines as the main processing equipment. When the cross-cut machine and the spiral double-knife cutting machine realize paper trimming and cutting, paper powder and paper fluff are easily generated due to the shearing force of the cutting tool. If the paper powder and paper fluff are not controlled and treated in time, the finished paper will be mixed with paper powder and paper fluff, affecting the customer's printing yield and printing efficiency.

[0009] The industry's solution to the problem is to replace the trimming cutter and the dust sticking roller, but there are still problems. When the trimming cutter is replaced, only the upper cutter is replaced, which has little effect, and the upper and lower cutters need to be replaced at the same time, which increases the frequency of replacing the cutters and increases production costs. The dust sticking roller can only stick to the surface or back of the suspended paper powder and paper fluff, but the paper powder and paper fluff on the cutting edge cannot be cleaned, and the installation position of the dust sticking roller has space requirements, which is inconvenient to install and increases the cost.
