Description

[Technical field]

[0001] The utility model relates to a waste cleaning technology for printed products, in particular to a waste cleaning device used in packaging printing. [Background technology]

[0002] In the printing industry, the function of the waste cleaning device is to remove the waste edges of the paper after die-cutting. Since the paper after die-cutting has been separated from the paper gripper row, the paper conveying method in the waste cleaning part should be considered first to achieve the best waste cleaning effect. There are roughly three ways to remove the waste paper edges: first, use an automatic die-cutting waste cleaning machine to clean the waste edges during the paper die-cutting process; second, use manual waste cleaning methods, that is, after the paper is die-cut, use the manual tearing method to remove the waste paper edges; third, use some simple equipment for waste cleaning, such as a vibrating waste cleaning machine, that is, use a vibrating waste cleaning knife to rigidly separate the finished product from the waste edges. This method has a slow processing speed and affects the quality of the finished product, so it is rarely used. The modular waste cleaning machine first makes a positive and negative mold according to the shape of the finished product, and then uses the working principle of the press to press the finished product out; this method is slow, inconvenient to operate, and has high requirements for paper, so it is rarely used.

[0003] The method of using an automatic die-cutting machine to clear waste is also the most traditional method. It is divided into primary and secondary waste clearing. This method has a better cleaning effect and can directly process finished products, but the cost is too high. In particular, the automatic waste clearing machine is expensive, the operation preparation time is long, and each time a different product is changed, a corresponding yin and yang template needs to be made. A set of waste clearing plates is sold at least 2,000 yuan in China, and the plate adjustment is also very complicated (at least 2 to 5 hours, and the installation of a waste clearing pre-installation table also takes 1 to 2 hours); and the use of the waste clearing function affects the die-cutting speed, and the paper is often scattered or the paper is not neatly collected after the waste is discharged. Therefore. Although there are a considerable number of automatic die-cutting waste clearing machines in China, very few are actually used. Most of them still use manual methods to clear waste. It is difficult to clear products with narrow paper edges, and it is easy for messy paper and rotten paper to affect the progress of waste clearing, resulting in low overall production efficiency of printed products. [Contents of the utility model]

[0004] The utility model provides a waste clearing device used in packaging printing, which can select different edge pressing templates and adjust the stamping thickness according to different products, effectively reduce production costs and alleviate workers' labor intensity.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] A waste removal device for packaging printing, used for automatically removing waste from printed packaging products, comprises a frame and a bottom support frame, wherein the bottom support frame is used for supporting the packaging products to be removed and automatically discharging waste materials:

[0007] An upper frame that can be lifted and slid in a vertical direction is suspended and installed on the frame directly above the bottom support frame, and slide bars that guide the upper frame to lift and slide up and down are respectively connected to the outer edges of both sides of the upper frame;

[0008] The lower side of the upper frame is equipped with a stamping contact adjustment block for selecting different thickness contact thickness modules according to different waste removal products;

[0009] The lower side of the stamping contact adjustment block is connected to a pressing template which can be disassembled and adjusted according to different products;

[0010] The center of the edge pressing template and the punching contact adjustment block are aligned to provide a male mold through hole consistent with the waste removal area of ​​the packaged product to be removed;

[0011] The frame corresponding to the male die through hole is also equipped with a waste removal head which moves up and down and passes through the male die through hole on the stamping contact adjustment block and the edge pressing template to punch out the waste removal area of ​​the packaged product on the bottom support frame.

[0012] Preferably, a pneumatic drive cylinder for driving the waste cleaning head to move up and down is installed on the frame.

[0013] Preferably, the bottom support frame is provided with a plurality of parallel supporting bars along the conveying direction of the packages for supporting the packages to be cleared, and forming supporting bars between each other so that the waste materials can automatically fall down and be discharged after being cleared.

[0014] Preferably, the lower edges on the left and right sides of the upper frame are also connected to two symmetrically arranged positioning strips for facilitating the disassembly and limited fixation of the stamping contact adjustment block. The outer end of each positioning strip is also threadedly connected to a plurality of evenly spaced adjustment screws for adjusting and fixing the installation position of the stamping contact adjustment block and locking the stamping contact adjustment block.

[0015] Preferably, two groups of symmetrically arranged sliding rods are respectively installed on the outer edges of both sides of the upper frame.

[0016] The beneficial effects of the utility model are:

[0017] Before the waste cleaning head is used to clean the packaging cleaning area, the packaging on the bottom support frame can be pressed and fixed in advance by the stamping contact adjustment block and the edge pressing template, which can effectively fix the narrow paper edge of the packaging paper to prevent messy and rotten paper from appearing during the waste cleaning process. Moreover, the stamping contact adjustment block can be replaced with different thicknesses according to different waste cleaning products, and the edge pressing template can also be disassembled and adjusted according to different products, so that different edge pressing templates can be selected according to different products and the stamping thickness can be adjusted to suit. This effectively reduces production costs, reduces the labor intensity of workers, and improves production efficiency.
