Description

Technical Field

[0001] The utility model mainly relates to the technical field of printing machines, in particular to an automatic waste discharge device for printing machines. Background Art

[0002] A printing press is a machine used to print text and images. Modern printing presses are generally composed of mechanisms such as plate mounting, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate, which is then mounted on a printing press. Then, ink is applied to the places on the printing plate where the text and image are, either manually or by a printing press. Then, the ink is directly or indirectly transferred to paper or other substrates, thereby replicating a printed product identical to the printing plate. Due to the shape of the finished product, the existing printing press needs to die-cut the printed product after printing, and the cut waste needs to be discharged.

[0003] Existing waste discharge devices for printing machines are divided into two types. One type is a waste discharge device for a trademark printing machine with a notice number of CN202573261U, which belongs to the technical field of self-adhesive label production. The technical scheme is: comprising a support arm (1), a waste discharge plate (2) and a paper pulling roller mounting plate (3) of a trademark printing machine head, one end of the support arm is connected to the waste discharge plate, and the other end of the support arm is arranged on the paper pulling roller mounting plate of the trademark printing machine head. A circular hole is arranged at one end of the support arm, and the support arm and the waste discharge plate are hinged together by bolts. A long hole (4) is arranged at the other end of the support arm, and the support arm and the paper pulling roller mounting plate of the trademark printing machine head are hinged together by bolts. The utility model is adopted to achieve that the distance and angle between the waste discharge plate and the paper pulling roller (5) of the trademark printing machine head can be arbitrarily adjusted according to the shape and size of the label, thereby ensuring that the trademark printing machine can easily discharge waste when producing labels of different sizes and shapes, thereby improving the production efficiency of the labels and reducing the production cost of the labels.

[0004] The waste discharge in the above scheme utilizes a waste discharge rod to collect the waste, which needs to be manually cleared regularly. Another waste discharge method is to discharge the waste directly after cutting. However, the cut waste is in strips or scattered, which is easy to scatter. Direct collection at the cutting position is easy to accumulate and affect the work of the shovel. Utility Model Content

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] Embodiment 1:

[0031] Please refer to the attached Figure 1-5 , an automatic waste discharge device for a printing press, comprising a waste shoveling device 1, the waste shoveling device 1 comprising a mounting platform 11, a waste shoveling roller 12 being mounted on the mounting platform 11, a waste platform 13 being mounted on the side end of the waste shoveling roller 12, a scraper 14 cooperating with the waste shoveling roller 12 being mounted on the side wall of the waste platform 13 close to the waste shoveling side, and characterized in that it also comprises an air blowing assembly 2, the air blowing assembly 2 comprising a blower 21 and an air duct 22, and the air blowing assembly 2 is arranged at the side end of the mounting platform 11, and the air blowing assembly 2 drives the waste on the waste platform 13 to be discharged by wind force.

[0032] In this embodiment, refer to the attached Figure 4 , Attachment Figure 5 A waste discharge pipe 23 connected to the waste platform 13 is installed on the right side of the mounting platform 11, and the air supply pipe 22 is connected to the side end of the waste discharge pipe 23. A wind guide plate 231 is installed in the waste discharge pipe 23 facing the side away from the mounting platform 11. The wind guide plate 231 can make the wind generated by the blower 21 blow outward, thereby guiding the waste on the waste platform 13 to be discharged.

[0033] In this embodiment, refer to the attached Figure 1-3 A fixed cylinder 41 connected to the waste platform 13 is installed on the left side of the mounting table 11, and a servo cylinder 4 is installed at the end of the fixed cylinder 41. A push plate 42 is movably connected in the fixed cylinder 41, and the push plate 42 is fixed on the output rod of the servo cylinder 4. The push plate 42 cooperates with the waste platform 13, and the servo cylinder 4 can drive the push plate 42 to move and push the waste to the waste discharge pipe 23 for discharge.

[0034] In this embodiment, refer to the attached Figure 3 A closing cover 3 for closing the waste platform 13 is installed on the top of the mounting platform 11 through a pin shaft. The closing cover 3 is made of glass, which is convenient for staff to check the accumulation of waste. A handle 31 is installed at the rear end of the closing cover 3. The closing cover 3 can prevent waste from floating out from the top of the mounting platform 11.

[0035] The use principle of the automatic waste discharge device of a printing machine in the utility model is:

[0036] After the scraper 14 shovels off the scattered waste, the waste falls on the waste platform 13, and the wind generated by the blower 21 is blown to the waste discharge pipe 23 through the air supply pipe 22. The wind is guided by the wind guide plate 231 in the waste discharge pipe 23 and blown to the right side of the mounting platform 11. At the same time, a certain suction force is generated on the waste on the waste platform 13, so that the waste enters the waste discharge pipe 23 and is blown out by the wind. If too much waste is accumulated, when this situation is checked through the closing cover 3, the servo cylinder 4 is started, and the servo cylinder 4 drives the push plate 42 to move toward the waste discharge pipe 23 to push the waste into the waste discharge pipe 23, and finally the waste is discharged from the waste discharge pipe 23.

[0037] Embodiment 2:

[0038] This embodiment replaces the working mode of the blower 21 in the first embodiment so that it can be applied to strip-shaped waste discharge. Figure 6-8 An air inlet pipe 24 is installed on the right side of the mounting platform 11, and the air delivery pipe 22 is connected to the end of the air inlet pipe 24. A waste outlet pipe 25 connected to the waste platform 13 is installed on the left side of the mounting platform 11. The air inlet pipe 24 is installed with pneumatic fan blades facing one side of the mounting platform 11. After the pneumatic fan blades are blown and rotated by the wind force of the blower 21, the wind speed of the wind blown into the waste platform 13 can be increased.

[0039] In this embodiment, the wind generated by the blower 21 enters the air inlet pipe 24 through the air delivery pipe 22, and directly blows the strip-shaped waste material shoveled off into the waste outlet pipe 25, so that the waste material is directly discharged from the waste outlet pipe 25 for waste discharge.

[0040] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
