Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of waste removing machine, especially relates to an upper die hole plate and waste removing device thereof. BACKGROUND

[0002] The waste edge cleaning of printed products in printing and packaging industry is called waste removing, which is a necessary procedure in the die cutting forming process of printed products, and the appearance of waste removing machine replaces manual hammer waste removing, reduces labor intensity and improves work efficiency.

[0003] At present, Japanese equipment adopts two groups of ejector pins to complete the waste removing work of printed products, wherein, the number of ejector pins required is quite large, the production of finished products is huge, the precision of the equipment is required to be high, the fault tolerance is low, the steps of installing the ejector pins are too complicated, the replacement is quite difficult, it takes half a day to install, the position of the ejector pins is controlled by the baffle, and the ejector pins of Japanese equipment need to be pushed and pressed from top to bottom. Since the waste removing machine often stacks a large number of printed products at a time, the ejector pin needs to bear a large force, therefore, a small diameter ejector pin cannot be used, however, in order to save the layout space of printed products, the printed products are closely arranged and distributed, a large diameter ejector pin is easy to press the printed products and the waste edge, which causes the printed products to be unable to separate from the waste edge or the waste edge to be unable to completely separate from the printed products, so that the waste removing machine is limited in waste removing under the conditions of the size of the ejector pin and the close arrangement of the printed products, the number of ejector pins is large, which greatly increases the installation time and the changeover time, thereby reducing the work efficiency, increasing the labor and time cost, and the large size ejector pin cannot be matched with the shape of the printed product when arranged, thereby reducing the pressing effect of the ejector pin and affecting the waste removing work of the printed product. UTILITARIAN CONTENT

[0004] The technical problem to be solved by the utility model embodiment is to provide an upper die hole plate and waste removing device thereof, which adopts a small size ejector pin, greatly reduces the number of ejector pins used, is more flexible in arrangement position, greatly shortens the changeover time, and improves the work efficiency.

[0005] To achieve the above objectives, this utility model discloses an upper mold plate, which is vertically and flexibly mounted on a waste removal device. A plurality of first pin holes are arrayed on the surface of the upper mold plate, with adjacent rows of first pin holes staggered and their outer rings aligned on the same horizontal line. A plurality of upper ejector pins are inserted into the first pin holes on the upper mold plate according to the shape of the printed product, resulting in a close arrangement of the first pin holes and an orderly arrangement of the upper ejector pins to obtain the required straight lines, curves, broken lines, and irregular lines. The pin arrangement trajectory is smooth and the linear shape is... Okay, it can better match the graphic of the printed product and ensure that the ejector pin can accurately press the waste edge of the printed product. The outer diameter of the upper ejector pin is 2mm-3mm and its length is 85mm-163mm. When the upper mold plate descends, the waste edge of the printed product is pressed by the several upper ejector pins. This can be used for printed products with extremely small waste edge size, which greatly saves the layout space of the printed products. The number of printed products stacked is 9-125 sheets, which reduces the pressure value required by the upper die during the waste removal process and greatly reduces the number of ejector pins used, shortens the plate change time and production cost.

[0006] Furthermore, the outer diameter of the upper ejector pin is 2mm, the length is 85mm-163mm, its ultimate load is 295N-808N, and the number of stacked papers pressed by the upper ejector pin is 9-31 sheets.

[0007] Furthermore, the outer diameter of the upper ejector pin is 3mm, the length is 85mm-163mm, its ultimate load is 1.72KN-3.01KN, and the number of stacked papers pressed by the upper ejector pin is 9-125 sheets.

[0008] This embodiment allows for flexible adjustment of the outer diameter and length of the upper ejector pin according to the waste edge size and stacking quantity of different printed products, ensuring the best clamping effect, further improving production efficiency and reducing costs.

[0009] This utility model also provides a waste removal device using the above-mentioned upper mold plate, including a platform, an upper mold limiting plate, and a lower mold limiting plate. The upper mold limiting plate is movably disposed above the platform, and the lower mold limiting plate is movably disposed below the platform. An upper mold plate is slidably disposed below the upper mold limiting plate, and a lower mold plate is mounted above the lower mold limiting plate. The upper mold plate has a plurality of first pin holes for inserting upper ejector pins, and the lower mold plate has a plurality of second pin holes for inserting lower ejector pins.

[0010] Furthermore, the surface of the platform is provided with several through holes corresponding to the second pinhole.

[0011] Further, the bottom surface of the upper die limiting plate is provided with a sliding groove on both sides, and the two sides of the upper die hole plate are in sliding fit with the sliding groove, so that the upper ejector pins are arranged conveniently, and the version changing efficiency is greatly improved.

[0012] Further, the paper receiving device is arranged at the rear of the platform and is used for receiving the printed products separated from the waste edge on the platform.

[0013] Compared with the prior art, the printing device has the beneficial effects that:

[0014] (1) The embodiment reduces the thickness of the printed products, effectively reduces the required pressure value in the waste removing process, greatly reduces the number of upper ejector pins, makes the arrangement positions of the upper and lower ejector pins more flexible, greatly shortens the version changing time and production cost, simultaneously shortens the length of the upper ejector pin, and greatly improves the load capacity of the upper ejector pin.
