[0002] Compression of printing waste paper is one of the common waste paper treatment methods in the printing industry. By effectively compressing printing waste paper, its volume can be reduced, making it easier to store and transport, and is conducive to subsequent waste paper recycling.

[0003] At present, when compressing printed waste paper, the waste paper is generally placed directly into a compression box, and then the cylinder drives the extrusion plate to move downward to compress the printed waste paper. During the compression process, some printed waste paper will be relatively wet, making it easy for the printed waste paper to adhere to the bottom of the extrusion plate during the compression process. The staff needs to manually clean the bottom of the extrusion plate, which not only delays the compression time of the printed waste paper, but also greatly increases the labor intensity of the staff. Therefore, a person skilled in the art provides a compression device for printed waste paper to solve the problems raised in the above background technology.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem that during the compression process of printed waste paper, the printed waste paper is easily attached to the bottom end of the squeezing plate, and the staff is required to manually clean the bottom end of the squeezing plate, which not only delays the compression time of the printed waste paper, but also greatly increases the labor intensity of the staff, the utility model provides a compression device for printed waste paper.

[0009] The cleaning mechanism is provided with two groups, which are symmetrically arranged on the left and right sides of the top plate and are used for cleaning the compression mechanism.

[0010] Preferably, the compression mechanism comprises

[0011] A cylinder is arranged at the upper end of the top plate;

[0014] A sleeve, arranged at the upper end of the top plate;

[0015] A connecting rod is movably arranged inside the sleeve, and its bottom end passes through the inside of the sleeve and is connected to the upper end of the extrusion plate;

[0016] A piston is slidably disposed inside the sleeve, and a bottom end of the piston is connected to an upper end of the connecting rod;

[0017] An air inlet pipe is arranged outside the sleeve and communicated with the sleeve, so as to allow external gas to enter the interior of the sleeve;

[0018] The air outlet pipe is arranged on the outside of the sleeve and communicated with the sleeve. One end of the air outlet pipe away from the sleeve penetrates into the interior of the cavity and is used for introducing the gas in the sleeve into the cavity.

[0023] Through the above technical scheme, the compression device for waste printing paper disclosed in the utility model is provided with a compression mechanism, a cleaning mechanism, a cavity and an air outlet. The waste printing paper can be compressed by driving the squeezing plate downward by the operation of the cylinder. After the compression of the waste printing paper is completed, air can be blown into the cavity by the cleaning mechanism. The air can be ejected through the air outlet to prevent the waste printing paper from being attached to the bottom end of the squeezing plate, so that the staff does not need to manually clean the bottom end of the squeezing plate, which greatly reduces the labor intensity of the staff and does not affect the compression efficiency of the waste printing paper.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The utility model discloses a compression device for waste printing paper. Figure 1-4 A compression device for waste printing paper comprises a compression box 1, a compression mechanism 4 and a cleaning mechanism 5. Four symmetrically distributed support plates 2 are arranged at the upper end of the compression box 1. The upper ends of the four support plates 2 are provided with a same top plate 3. The middle part of the upper end of the top plate 3 is provided with a compression mechanism 4 for compressing waste printing paper, and cleaning mechanisms 5 for cleaning the compression mechanism 4 are arranged on both left and right sides of the upper end of the top plate 3.

[0031] Reference Figure 2 The compression mechanism 4 includes a cylinder 401 and a squeezing plate 402. The cylinder 401 is arranged at the upper end of the top plate 3, and the squeezing plate 402 is arranged at the bottom end of the cylinder 401, and is used to compress the printed waste paper. A cavity 6 is opened inside the squeezing plate 402, and a plurality of air outlet holes 7 connected to the cavity 6 are opened at the bottom end of the squeezing plate 402.

[0032] By adopting the above technical solution, after the printed waste paper is poured into the compression box 1, the cylinder 401 drives the squeezing plate 402 to move downward to compress the printed waste paper.

[0033] Reference Figure 4The cleaning mechanism 5 includes a sleeve 501, a connecting rod 502, a piston 503, an air inlet pipe 504 and an air outlet pipe 505. The sleeve 501 is arranged at the upper end of the top plate 3, the connecting rod 502 is movably arranged inside the sleeve 501, the bottom end of the connecting rod 502 passes through the interior of the sleeve 501 and is connected to the upper end of the extrusion plate 402, the piston 503 is slidably arranged inside the sleeve 501 and the bottom end is connected to the upper end of the connecting rod 502, the air inlet pipe 504 and the air outlet pipe 505 are both arranged on the outside of the sleeve 501 and are connected to the sleeve 501, and the end of the air outlet pipe 505 away from the sleeve 501 passes through the interior of the cavity 6, which is used to introduce the gas in the sleeve 501 into the cavity 6; a one-way valve 8 is arranged on the air inlet pipe 504 and the air outlet pipe 505.

[0034] By adopting the above technical solution, when the extrusion plate 402 moves downward, the piston 503 will be driven to move downward, so that the outside air can be introduced into the interior of the sleeve 501 through the air inlet pipe 504, and then when the extrusion plate 402 moves upward, the air inside the sleeve 501 can be introduced into the interior of the cavity 6 through the air outlet pipe 505 through the piston 503, and finally sprayed out through the air outlet hole 7 to prevent the bottom end of the extrusion plate 402 from adhering to printed waste paper.

[0035] Reference Figure 2 Two symmetrically distributed limiting rings 9 are arranged on the rear side of the top plate 3 , one end of the air outlet pipe 505 passes through the limiting ring 9 , and a sponge is arranged inside the limiting ring 9 .

[0036] By adopting the above technical solution, the air outlet pipe 505 is not easily entangled or knotted when moving due to the limiting ring 9, and the protection of the air outlet pipe 505 is improved due to the sponge.

[0037] Reference Figure 1 A door 10 is rotatably provided on the front of the compression box 1 to facilitate taking out the compressed printed waste paper.

[0038] By adopting the above technical solution, the box door 10 can be opened after the compression of the printed waste paper is completed, so that the compressed printed waste paper can be easily taken out.

[0039] Working principle: When the utility model is in use, the electrical components appearing in the present application are all connected to an external power supply and a control switch. First, the printed waste paper is poured into the compression box 1, and then the cylinder 401 works to drive the squeezing plate 402 to move downward to compress the printed waste paper. When the squeezing plate 402 moves downward, the piston 503 can be driven to slide inside the sleeve 501 through the connecting rod 502. At this time, the outside air can enter the sleeve 501 through the one-way valve 8 on the air inlet pipe 504. Then, after the compression of the printed waste paper is completed, the squeezing plate 402 moves upward to drive the piston 503 to slide upward, and the air inside the sleeve 501 can be introduced into the cavity 6 through the air outlet pipe 505, and finally sprayed out through the air outlet 7, so that the bottom end of the squeezing plate 402 can be prevented from being attached to the printed waste paper, so that the printed waste paper attached to the bottom end of the cylinder 401 does not need to be manually cleaned by the staff, thereby greatly reducing the labor intensity of the staff and not affecting the compression efficiency of the printed waste paper.

[0040] When the utility model is in use, the bottom end of the squeezing plate 402 can be automatically cleaned during the process of compressing the printed waste paper, without the need for manual cleaning by the staff, so that the bottom end of the squeezing plate 402 is not easy to adhere to the printed waste paper, which greatly reduces the labor intensity of the staff and does not affect the compression efficiency of the printed waste paper.
