Description

Technical Field

[0001] This utility model relates to the field of waste paper recycling technology, specifically to a device for the efficient recycling and reuse of printing waste paper edges. Background Technology

[0002] Waste paper recycling refers to the process of transforming waste paper products into recycled pulp through systematic classification, cleaning, deinking, pulping and other processes, and then further producing recycled paper products. Recycling and reuse of printing waste paper edges refers to the paper scraps generated during the printing production process, that is, the non-finished waste edges generated in the cutting process due to layout design or paper size matching, such as book binding edges and packaging box cutting scraps.

[0003] Based on the above, the following problems were found: Current waste paper recycling requires screening the waste paper first, then crushing and pulping it, which is a rather cumbersome process. However, printing waste paper is a stable and clean source of waste paper. Using this method for pulping and recycling is too inefficient and inconvenient to use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a device for the efficient recycling and reuse of printing waste paper edges, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a device for the efficient recycling and reuse of waste printing paper edges, so as to solve the problems mentioned in the background art.

[0006] A device for efficient recycling and reuse of waste printing paper scraps includes a pulping assembly. The pulping assembly includes a pulping barrel, a top beam fixedly installed on the top of the pulping barrel, a mounting base fixedly installed at one end of the top of the top beam, and a crushing assembly fixedly installed on the top of the mounting base. The crushing assembly includes a gear cavity, a guide cover provided on the top of the gear cavity, and a feeding port opened at the bottom of the guide cover, the feeding port facing the inside of the pulping barrel. A rotating frame is rotatably connected inside the guide cover, a filter screen is fixedly installed on the outside of the rotating frame, a first blade is fixedly installed inside the rotating frame, a rotating shaft is rotatably connected to the middle of the rotating frame, and a second blade is fixedly installed on the outside of the rotating shaft. The first blade and the second blade are arranged alternately.

[0007] By adopting the above technical solution, the pulping assembly facilitates the preliminary pulping of crushed and filtered printing waste paper scraps, providing a basic feedstock for recycled pulp production. The pulping tank provides space for holding waste paper scraps and water. The top beam provides a foundation for the pulping auger and allows for easy observation of the pulping process and water addition. The mounting base provides a foundation for the crushing assembly. The feed inlet guides the waste paper scraps through a guide hood, allowing the scraps to flow smoothly from the feed inlet. The feed inlet inserts waste paper into the pulping barrel for pulping. The rotating frame provides a mounting base for the filter screen and the first blade, allowing waste paper edges to be easily fed into the rotating frame for crushing. The crushed waste paper edges, now of suitable size, pass through the filter screen and enter the guide cover. The rotating shaft provides a mounting base for the second blade, and the second blade allows the rotating shaft and rotating frame to rotate coaxially but in opposite directions. This allows the second blade to cut the waste paper edges in an alternating manner with the first blade, improving cutting efficiency and filtering during the cutting process, further enhancing recycling efficiency.

[0008] Furthermore, the inner side of the top of the guide cover is rotatably connected to the rotating frame, the inner side of the bottom of the guide cover has a gap with the rotating frame, and the bottom end of the rotating frame is rotatably connected to the bottom end of the guide cover.

[0009] By adopting the above technical solution, a gap is left between the bottom inner side of the guide cover and the rotating frame, which facilitates the sliding of waste paper edge debris that passes through the filter screen towards the inlet inside the guide cover, making it convenient to put the waste paper edge debris into the pulping barrel.

[0010] Furthermore, a crushing motor is fixedly installed on the top of the gear cavity, and a third bevel gear is fixedly installed at the output end of the crushing motor.

[0011] By adopting the above technical solution and by setting the crushing motor, it is convenient for the crushing motor to drive the third bevel gear to rotate.

[0012] Furthermore, the third bevel gear is meshed with a first bevel gear and a second bevel gear at both ends. The first bevel gear is fixedly connected to the rotating frame, and the second bevel gear is fixedly connected to the rotating shaft.

[0013] By adopting the above technical solution, the arrangement of the first bevel gear and the second bevel gear facilitates the rotation of the third bevel gear, which drives the first bevel gear and the second bevel gear to rotate, thereby enabling the rotating frame to rotate coaxially and in opposite directions with the rotating shaft.

[0014] Furthermore, a auger is rotatably connected to the middle of the top beam, and a scraper is fixedly installed at the bottom of the auger.

[0015] By adopting the above technical solution, the auger facilitates the rotation of the auger inside the pulping drum to mix and crush waste paper scraps and water to form pulp, which is convenient for subsequent recycling and reuse. The rotation of the auger can drive the scraper to rotate.

[0016] Furthermore, a breaker motor is fixedly installed at the top of the top beam away from the mounting base, and a worm gear is fixedly installed at the output end of the breaker motor. The worm gear is meshed with a worm wheel, and the worm wheel is fixedly connected to the top of the breaker auger.

[0017] By adopting the above technical solution, the setting of the auger motor facilitates the operation of the auger motor, which drives the worm gear to rotate, thereby controlling the rotation of the auger.

[0018] Furthermore, a filter plate is fixedly installed on the bottom inner side of the pulping barrel, and the filter plate is located at the bottom of the scraper.

[0019] By adopting the above technical solution, the filter plate facilitates the filtration and collection of the well-crushed pulp, and the scraper rotates on the top of the filter plate to remove the debris that causes blockage, thus preventing the filter plate from clogging.

[0020] Furthermore, a good paddle bucket is fixedly installed on the outer side of the bottom end of the paddle-making barrel, the good paddle bucket is covered on the outer side of the bottom end of the filter plate, and a paddle discharge interface is opened at the bottom end of the good paddle bucket.

[0021] By adopting the above technical solution, the paddle discharge interface facilitates the collection of filtered paddles by the paddle bucket. The paddle discharge interface also allows for the installation of an external control valve to control the discharge of the paddles, facilitating subsequent recycling and reuse.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: The pulping assembly facilitates the preliminary pulping of crushed and filtered printing waste paper scraps, providing a basic feedstock for recycled pulp production. The pulping tank facilitates the holding of waste paper scraps and water, providing pulping space. The top beam facilitates the installation of the pulping auger and allows for easy observation of the pulping status and water addition. The mounting base facilitates the installation of the crushing assembly. The feeding port facilitates the guidance of the guide hood to feed the waste paper scraps into the pulping tank for pulping. The rotating frame provides a mounting base for the filter screen and the first blade, facilitating the feeding of waste paper edges into the frame for crushing. The crushed waste paper edges, now of suitable size, pass through the filter screen and enter the guide cover. The rotating shaft provides a mounting base for the second blade, and its design allows the shaft and frame to rotate coaxially but in opposite directions. This allows the second blade to interlock with the first blade, improving cutting efficiency and enabling filtration during the cutting process, further enhancing recycling efficiency. This invention efficiently crushes and pulps waste paper edges, effectively improving recycling efficiency and possessing high practical value. Attached Figure Description
