Waste paper processing device for green printing of cartons

Abstract

The invention discloses a waste paper processing device for green printing of cartons, comprising: a supporting leg fixedly connected to the bottom, a crushing transmission assembly fixedly connected to the top, a crusher fixedly connected to the top, a connecting box fixedly connected to the top of the crusher, a connecting plate fixedly connected to the top of the connecting box, and a waste paper compression mechanism arranged on the inner wall of the connecting box. The invention relates to the technical field of waste paper processing. By arranging the waste paper compression mechanism, the thread lead angle of the outer wall of the threaded rod is greater than forty-five degrees, so the friction force of the sliding sleeve descending through the rotation of the thread is low, and the sliding sleeve can be rotated and lifted normally, thereby driving the sliding sleeve to rotate synchronously with the rotating rod and the conical block. As the conical block rotates, the waste paper scraps on the surface of the conical block that were originally attached to the surface of the conical block due to static friction will be thrown off through the rotation, so that the waste paper scraps lose the friction force of static friction, thereby sliding on the inclined surface of the outer wall of the conical block, thereby improving the feeding effect of the waste paper scraps.

[0016] Preferably, a connecting hole is opened on the outer wall of the elastic net, a telescopic blocking rod is fixedly connected to the outer wall of the sliding sleeve B, and a cutting blade is fixedly connected to the top of the fixing seat.

[0017] The present invention provides a waste paper processing device for green printing of cartons. It has the following beneficial effects:

[0018] 1. The present invention provides a waste paper compression mechanism. After the paper scraps are placed on the inlet plate and piled up, the pressing ball, the rotating rod, the conical block and the circular plate are manually pressed down. When the connecting channel is opened, the sliding sleeve is pushed to slide and rotate down through the threads of the outer wall of the threaded rod. The thread lead angle of the outer wall of the threaded rod is forty-five degrees. Therefore, the friction of the sliding sleeve through the thread rotation when it descends is relatively low, and it can be rotated and lifted normally, thereby driving the sliding sleeve, the rotating rod and the conical block to rotate synchronously. As the conical block rotates, the waste paper scraps on the surface of the conical block that were originally attached to the surface of the conical block due to static friction will be thrown off through the rotation, so that the waste paper scraps lose the friction of static friction, and thus slide down on the inclined surface of the outer wall of the conical block, thereby improving the feeding effect of the waste paper scraps.

[0019] 2. The present invention provides a waste paper compression mechanism, and the inner wall of the sliding sleeve is filled with water through the communication. When the sliding sleeve descends, the water on the inner wall of the sliding sleeve is squeezed through the one-way air hole into the circular hole, and enters the conical block and is sprayed out through the spray hole, so that the paper scraps accumulated on the top at this time on the spray hole are sprayed and wetted, thereby avoiding the problem that the paper scraps are relatively thin and cannot be quickly crushed by the crushing wheel when they fall into the crusher. Then, it is easier for the waste paper scraps to collapse into a ball after being dampened, so that they become soft and adhere to each other into a ball, and the weight is increased so that they can quickly enter the crushing wheel for crushing, and the rotating conical block rotates and sprays the sprayed water more evenly on each piece of paper above, further improving the effect of softening and increasing its weight.

[0020] 3. The present invention provides a compacting mechanism. When the pressing ball is pressed down, the sliding rod of the outer wall and the sliding sleeve A and the sliding sleeve B are driven to synchronously descend. When one end of the sliding sleeve B contacts the inner wall of the inlet plate, it is squeezed by the inclined surface of the inner wall of the inlet plate. As the sliding sleeve B continues to descend, it is continuously squeezed to push the sliding sleeve A to telescopically slide on the outer wall of the sliding rod. As a result, the sliding sleeve B, the sliding sleeve A and the sliding rod are gradually shortened to adapt to the gradually decreasing diameter of the bottom of the inlet plate. Thus, a large amount of paper scraps are pressed downward through a plurality of sliding rods, the sliding sleeve A and the sliding sleeve B, so that the paper scraps are squeezed into the smaller opening at the bottom of the inlet plate. As a result, when the paper scraps are put into the connecting cover, they are first squeezed into balls by the gradually shrinking diameter of the inlet plate. The balled paper scraps are more easily crushed along with the water sprayed from the spray hole, and the problem of cardboard shells opening to each other and being unable to fall and causing blockage and being difficult to crush is reduced.

[0021] 4. The present invention sets a compacting mechanism. When the sliding rod descends, the rotation of the rotating rod also drives the pressing ball and the sliding rod to rotate synchronously, so that the sliding rod and the sliding sleeves A and B also rotate synchronously. The top of the paper scraps is moved back and forth by rotation, so that the paper scraps are evenly accumulated inside the entrance plate, avoiding the problem that some paper scraps are clumped and partially opened, resulting in uneven distribution and blockage in the entrance plate. The elastic net adaptively shortens the sliding sleeve B, sliding sleeve A and sliding rod to perform corresponding elastic contraction and cover all the paper scraps to prevent the paper scraps from falling out when they are compressed and pushed into the connecting cover.

[0022] 5. The present invention provides a compacting mechanism. When the pressing ball is pressed to open the connecting channel to compress and push the paper scraps into the connecting cover, the circular cover below the circular plate and the lifting plate can be driven to descend synchronously, and the accumulated paper scraps at the bottom of the connecting cover that enter the grinder for crushing can be further pushed down and squeezed, and the paper scraps that are accumulated in a large area at the exit position of the bottom of the connecting cover can be flattened, thereby increasing the adhesion between the paper scraps and increasing the weight of the clumped paper scraps. When they fall into the grinder, they will be hooked by the tip of the crushing wheel more quickly to complete the crushing. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] Example 1: Please refer to Figure 1-3 The present invention provides a technical solution: a waste paper processing device for carton green printing, comprising a workbench 9, a support leg 1 is fixedly connected to the bottom of the workbench 9, a crushing transmission assembly 5 is fixedly connected to the top of the workbench 9, a crusher 6 is fixedly connected to the top of the workbench 9, a connecting box 2 is fixedly connected to the top of the crusher 6, a connecting plate 7 is fixedly connected to the top of the connecting box 2, and a waste paper compression mechanism 3 is arranged on the inner wall of the connecting box 2;

[0038] The waste paper compression mechanism 3 comprises:

[0039] The connecting cover 301 is in the shape of a truncated cone. A fixing seat is fixedly connected to the inner wall of the connecting cover 301. A fixing rod 309 is fixedly connected to one end of the fixing seat. A threaded rod 308 is fixedly connected to the top of the fixing rod 309. The connecting cover 301 is used to temporarily store and place paper scraps.

[0040] The threaded rod 308 has a sliding sleeve 305 slidably connected to its outer wall, a circular plate 304 is rotatably connected to the top of the sliding sleeve 305, and a conical block 303 is rotatably connected to the top of the circular plate 304. The threaded rod 308 enables the sliding sleeve 305 to rotate on its outer wall thread.

[0041] The waste paper to be shredded is placed in the inlet plate 302, then enters the connection cover 301 through the inlet plate 302, and falls into the shredder 6 through the bottom opening of the connection cover 301, and the shredder 6 is shredded by starting the shredding transmission assembly 5, thereby completing the shredding of the waste paper;

[0042] After the waste paper is put into the inlet plate 302, the pressing ball 314 is manually pressed to push the rotating rod 313 below to synchronously descend with the conical block 303 and the circular plate 304. When the conical block 303 descends, the connection between the connecting box 2 and the outside is automatically opened, so that the waste paper scraps will also begin to fall through the larger gap between the conical block 303 and the inlet plate 302 after the conical block 303 descends, and begin to slide downward along the inclined surface of the outer wall of the conical block 303, so as to keep the conical block 303 closed when the waste paper is not put into the connecting box 2, reduce the falling of non-paper scraps, and protect the cleanliness of the inner wall of the connecting box 2;

[0043] Example 2: Please refer to Figure 1-10 On the basis of the first embodiment, the present invention provides a technical solution: a limited telescopic rod 316 is fixedly connected to the bottom of the circular plate 304, a fixed ring 306 is fixedly connected to the bottom end of the limited telescopic rod 316, a connecting rod 307 is fixedly connected to the bottom of the fixing ring 306, and one end of the connecting rod 307 is fixedly connected to the outer wall of the threaded rod 308.

[0044] A spring 315 is fixedly connected to the top of the fixing ring 306 , and the top of the spring 315 is fixedly connected to the bottom of the circular plate 304 .

[0045] The outer wall of the sliding sleeve 305 is rotatably connected to the connecting pipe 8 through a bearing, the top of the sliding sleeve 305 is fixedly connected to a rotating rod 313, and the top of the rotating rod 313 is fixedly connected to a pressing ball 314.

[0046] A circular cover 317 is fixedly connected to the bottom of the circular plate 304, and a lifting plate 318 is fixedly connected to the bottom of the circular cover 317. The thread angle of the threaded rod 308 on the outer wall is 45 degrees.

[0047] After the paper scraps are placed on the inlet plate 302 and piled up, the pressing ball 314 is manually pressed to lower the rotating rod 313, the conical block 303 and the circular plate 304 to open the connecting channel, which will push the sliding sleeve 305 to slide and rotate on the outer wall of the threaded rod 308 through the threads of the outer wall of the threaded rod 308. The thread lead angle of the outer wall of the threaded rod 308 is forty-five degrees, so the friction of the sliding sleeve 305 when it descends through the rotation of the threads is low, and it can rotate and lift normally, thereby driving the sliding sleeve 305 to rotate synchronously with the rotating rod 313 and the conical block 303. As the conical block 303 rotates, the waste paper scraps on the surface of the conical block 303 that were originally attached to the surface of the conical block 303 due to static friction will be thrown off through the rotation, so that the waste paper scraps lose the friction of static friction, and thus slide on the inclined surface of the outer wall of the conical block 303, thereby improving the feeding effect of the waste paper scraps.

[0048] The inner wall of the sliding sleeve 305 is filled with water through the connecting pipe 8, and when the sliding sleeve 305 descends, the water on the inner wall of the sliding sleeve 305 is squeezed through the one-way air hole 310 into the circular hole 311, and enters the conical block 303 and is sprayed out through the spray hole 312, so as to spray and wet the paper scraps accumulated on the top of the spray hole 312 at this time, thereby avoiding the problem that the paper scraps are relatively light and thin and cannot be quickly crushed by the crushing wheel when they fall into the crusher 6. Then, it is easier for the waste paper scraps to collapse into a ball after being dampened, so that they become soft and adhere to each other into a ball, and the weight is increased so that they can quickly enter the crushing wheel for crushing, and the rotating conical block 303 will spray the sprayed water more evenly on each piece of paper above, further improving the effect of softening and increasing its weight;

[0049] Because the conical block 303 is fixedly connected to the inner wall of the connecting cover 301, the fixing rod 309, the threaded rod 308 and the connecting rod 307 are also fixed and cannot move, so the fixing ring 306 is fixed by the connecting rod 307 and thus remains stationary, and when the sliding sleeve 305 descends, it will slide down on the outer wall of the threaded rod 308 and the lower end will pass through the inside of the fixing ring 306, squeezing the spring 315 to deform, thereby achieving normal lifting work;

[0050] The one-way air hole 310 is a one-way air groove, and water will only enter the circular hole 311 and the inner wall of the conical block 303 through the one-way air hole 310, and will not be drawn back from the conical block 303. Therefore, when the sliding sleeve 305 is lowered and the water inside is squeezed by the threaded rod 308, it will be sprayed out through the spray hole 312. After the paper scraps are crushed and fall, release the hand pressing the pressing ball 314, and the circular plate 304 will rebound to its original position and rise with the elastic force of the spring 315. At this time, the sliding sleeve 305 and the threaded rod 308 are When the sliding sleeve 305 moves away from each other, water will be pumped into the sliding sleeve 305 through the connecting pipe 8 without backflow. Therefore, each time the pressing ball 314 is pressed to make the sliding sleeve 305 descend, the water pumped into the sliding sleeve 305 will be sprayed out through the spray hole 312, and the outer wall of the sliding sleeve 305 is rotatably connected with the connecting pipe 8 through the bearing. Therefore, when the sliding sleeve 305 rotates, the annular groove on the outer wall will be used to communicate with the connecting pipe 8 through the inside of the bearing. When the sliding sleeve 305 rotates, it can also be connected;

[0051] Example 3: Please refer to Figure 1-13 On the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: a compacting mechanism 4 is arranged on the outer wall of the pressing ball 314, the compacting mechanism 4 comprises a sliding rod 401, one end of the sliding rod 401 is fixedly connected to the outer wall of the pressing ball 314, a sliding sleeve A402 is slidably connected to the outer wall of the sliding rod 401, a sliding sleeve B403 is slidably connected to the outer wall of the sliding sleeve A402, and one end of the sliding sleeve B403 contacts the inner wall of the inlet plate 302.

[0052] An elastic net 404 is fixedly connected to the outer wall of the sliding sleeve B403 , and one end of the elastic net 404 is fixedly connected to the outer wall of the pressing ball 314 .

[0053] A connecting hole 405 is formed on the outer wall of the elastic net 404, a telescopic blocking rod 406 is fixedly connected to the outer wall of the sliding sleeve B403, and a cutting blade 407 is fixedly connected to the top of the fixing seat;

[0054] As the pressing ball 314 is pressed down, the pressing ball 314 will drive the sliding rod 401 on the outer wall and the sliding sleeve A402 and the sliding sleeve B403 to synchronously descend. When one end of the sliding sleeve B403 contacts the inner wall of the inlet plate 302, it will be squeezed by the inclined surface of the inner wall of the inlet plate 302. As the sliding sleeve B403 continues to descend, it is continuously squeezed and pushes the sliding sleeve A402 to extend and slide on the outer wall of the sliding rod 401, so that the sliding sleeve B403, the sliding sleeve A402 and the sliding rod 401 are gradually extended and shortened. Adapting to the gradually decreasing diameter of the bottom of the inlet plate 302, the paper scraps are pressed downward by the sliding rods 401, the sliding sleeve A402, and the sliding sleeve B403, so that the paper scraps are squeezed into the smaller opening at the bottom of the inlet plate 302, so that when the paper scraps are put into the connection cover 301, they are first squeezed into a ball by the gradually shrinking diameter of the inlet plate 302, and the balled paper scraps are more easily crushed with the water sprayed by the spray hole 312, which also reduces the problem of cardboard shells opening each other and being unable to fall down, causing blockage and difficulty in crushing;

[0055] When the sliding rod 401 descends, the rotation of the rotating rod 313 also drives the pressing ball 314 to rotate synchronously with the sliding rod 401, so that the sliding rod 401 and the sliding sleeve A402 and the sliding sleeve B403 also rotate synchronously. The top of the paper scraps is moved back and forth by the rotation, so that the paper scraps are evenly placed inside the inlet plate 302, and the problem of uneven distribution and clogging in the inlet plate 302 is avoided. The elastic net 404 adaptively shortens the sliding sleeve B403, the sliding sleeve A402, and the sliding rod 401 to shrink accordingly, and completely covers the paper scraps, so as to prevent the paper scraps from falling out when being compressed and pushed into the connecting cover 301.

[0056] As the pressing ball 314 is pressed to open the connecting channel and compress the paper scraps into the connecting cover 301, the circular cover 317 and the lifting plate 318 below the circular plate 304 can also be driven to descend synchronously, thereby further pushing down and squeezing the accumulated paper scraps that enter the pulverizer 6 for pulverization at the bottom of the connecting cover 301, flattening the large-area paper scraps that are clumped at the bottom exit of the connecting cover 301, increasing the adhesion between the paper scraps, and then increasing the weight of the clumped paper scraps, so that when they fall into the pulverizer 6, they will be hooked by the tip of the pulverizing wheel more quickly to complete the pulverization.

[0057] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
