DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0037] In conjunction with the instruction manual Figure 1 To Attachment Figure 5 It can be known that the newsprint impregnation device provided by the utility model mainly includes the following parts or components: a mixing tank 10 , a first stirring shaft 12 , a second stirring shaft 13 , a connecting assembly 20 , and a filter box 40 .

[0038] In the utility model, the top of the mixing tank 10 is provided with an opening and a feed port 101, and a rotatable turntable 11 is provided on the opening; a first stirring shaft 12 is provided in the mixing tank 10, and its upper end passes through the turntable 11 and is connected to the driving component 30, and rotates alternately forward and reverse under the drive of the driving component 30, and a first stirring paddle 121 is provided on the first stirring shaft 12; a plurality of second stirring shafts 13 are provided in the mixing tank 10, parallel to the first stirring shaft 12, and the plurality of second stirring shafts 13 are evenly distributed in the circumferential direction of the first stirring shaft 12, and the upper ends of the plurality of second stirring shafts 13 pass through the turntable 11 and are connected to the driving component 30, and the first stirring shaft 12 is provided with a first stirring paddle 121; a plurality of second stirring shafts 13 are provided in the mixing tank 10, parallel to the first stirring shaft 12, and the plurality of second stirring shafts 13 are evenly distributed in the circumferential direction of the first stirring shaft 12, and the plurality of second stirring shafts 13 are connected to the driving component 30, and the first stirring shaft 12 is ... The turntable 11 is passed through; the connecting component 20 is connected to the first stirring shaft 12 and multiple second stirring shafts 13 respectively. The first stirring shaft 12 drives the multiple second stirring shafts 13 through the connecting component 20, and rotates alternately forward and reverse around the first stirring shaft 12, and under the action of the transmission member, the second stirring shaft 13 rotates on its own, and a second stirring paddle 131 is arranged on the second stirring shaft 13; the filter box 40 is arranged on one side of the mixing tank 10, and the liquid inlet thereon is connected with the mixing tank 10 through the connecting pipe 15, and a waste outlet is arranged on the filter, and the filter box 40 is used to filter the material after the stirring is completed.

[0039] During operation, the impregnation solvent and waste paper are sent to the mixing tank 10 from the feed port 101, and the driving component 30 drives the first stirring shaft 12 to rotate alternately forward and reverse, and the first stirring paddle 121 on the first stirring shaft 12 stirs the material. At the same time, the first stirring shaft 12 drives multiple second stirring shafts 13 through the connecting component 20, and rotates alternately forward and reverse with the first stirring shaft 12 as the center. Because the turntable 11 can rotate, there will be no interference when the multiple second stirring shafts 13 rotate, and under the action of the transmission member, the second stirring shaft 13 rotates, and the second stirring paddles 131 on the multiple second stirring shafts 13 stir the material. Compared with the prior art, the first stirring shaft 12 and the multiple second stirring shafts 13 cooperate to stir the material, which can effectively shorten the time for stirring the material evenly and improve the work efficiency. After stirring evenly, the material is sent from the connecting pipe 15 to the filter box 40 for filtration.

[0040] Specifically, the first stirring paddle 121 and the second stirring paddle 131 are staggered, which can effectively stir the material. In addition, the first stirring paddle 121 and the second stirring paddle 131 are both provided with a plurality of through holes, which can effectively reduce the resistance of the first stirring paddle 121 and the second stirring paddle 131 during stirring.

[0041] As an embodiment, in conjunction with the attached Figure 2It can be seen that the connection assembly 20 includes a plurality of connection rods 21, which are evenly distributed in the circumferential direction of the first stirring shaft 12 above the turntable 11, and correspond one to one with the plurality of second stirring shafts 13. The first end of each connection rod 21 is connected to the first stirring shaft 12, and a connection column 22 is provided at the lower side of the second end of the connection rod 21, and the lower end of the connection column 22 is connected to the upper end of the second stirring shaft 13. The transmission member is a ring gear 14 provided on the mixing tank 10, and the inner teeth of the ring gear 14 are respectively meshed with the first gears 132 on the plurality of second stirring shafts 13.

[0042] When the first stirring shaft 12 rotates, the multiple connecting rods 21 drive the multiple connecting columns 22 to rotate alternately forward and reverse around the first stirring shaft 12. The multiple connecting columns 22 drive the multiple second stirring shafts 13 to rotate alternately forward and reverse around the first stirring shaft 12. At the same time, when the second stirring shaft 13 rotates, it drives the first gear 132 to rotate. Since the first gear 132 is meshed with the ring gear 14, the second stirring shaft 13 also rotates on its own, thereby stirring the material.

[0043] As an embodiment, in conjunction with the attached Figure 2 It can be seen that the driving assembly 30 includes a first rack 33, which moves horizontally back and forth under the drive of the first hydraulic cylinder 31, and the first rack 33 is meshed with the second gear 32 on the first stirring shaft 12. The first hydraulic cylinder 31 drives the first rack 33 to move horizontally back and forth, and the first rack 33 drives the first stirring shaft 12 to rotate forward and reverse alternately through the second gear 32.

[0044] As an embodiment, in conjunction with the attached Figure 3 , Attachment Figure 4 It can be seen that the filter box 40 includes a partition 41 which is horizontally arranged in the filter box 40, and a discharge port 42 is arranged on it, and the discharge port 42 is opposite to the liquid inlet; the water filter cartridge 43 is arranged in the filter box 40 below the partition 41, and a plurality of water filter holes 431 are arranged on it, the upper end of the water filter cartridge 43 is communicated with the discharge port 42, and the upper end of the water filter cartridge 43 is connected to the rotating shaft of the discharge port 42, and the lower end of the water filter cartridge 43 is provided with a sealing door 44 that can be opened and closed; the upper end of the rotating sleeve 45 extends into the bottom of the filter box 40 and is sleeved on the lower end of the water filter cartridge 43, and the lower end of the water filter cartridge 43 is provided with a guide key 432 along its axial direction, and the guide key 432 is slidably connected with the guide groove arranged on the inner wall of the rotating sleeve 45, and the first motor 46 drives the rotating sleeve 45 to rotate, and the lower end of the rotating sleeve 45 is provided with a sealing cover 451 that can be opened and closed.

[0045] The evenly stirred material enters the filter box 40 from the connecting pipe 15, and enters the water filter cartridge 43 through the discharge port 42 on the partition 41. The waste liquid in the material enters the filter box 40 through the water filter hole 431 and is discharged out of the filter box 40 through the waste outlet. The rotating sleeve 45 and the water filter cartridge 43 are slidably connected with the guide groove through the guide key 432. When the first motor 46 drives the rotating sleeve 45 to rotate, the rotating sleeve 45 drives the water filter cartridge 43 to rotate, which can effectively throw the corresponding waste liquid into the filter box 40.

[0046] Specifically, the middle part of the partition 41 is conical, and the discharge port 42 is arranged at the small-diameter end of the cone, which can facilitate the material to fall into the water filter cartridge 43 through the discharge port 42, reducing unnecessary waste, and the middle part of the partition 41 is made of stainless steel, and its smoothness can make the material flow into the water filter cartridge 43 more easily.

[0047] In this embodiment, in conjunction with the attached Figure 5 It can be seen that a drying assembly 50 is arranged in the filter box 40 on one side of the water filter cartridge 43, and the drying assembly 50 includes a heating plate 51, which is arranged in the filter box 40 and moves away from or close to the water filter cartridge 43 under the drive of the telescopic assembly. The telescopic assembly includes a fixed block 52, which is arranged on the inner wall of the filter box 40 on one side of the water filter cartridge 43 and is parallel to the heating plate 51; the second rotating shaft 53 is rotatably arranged on the fixed block 52 under the drive of the second motor 531; two first connecting rods 54 are symmetrically arranged on both sides of the fixed block 52, and the first ends thereof are respectively connected to the second rotating shaft 53, and the second ends are respectively hinged to the two sides of the heating plate 51; two second connecting rods 55 are symmetrically arranged on both sides of the fixed block 52 and are parallel to the first connecting rod 54, and the first ends of the two second connecting rods 55 are respectively hinged to the two sides of the fixed block 52, and the second ends are respectively hinged to the two sides of the heating plate 51.

[0048] During operation, the second motor 531 drives the first connecting rod 54 to swing through the second rotating shaft 53, and the heating plate 51 can be driven to tilt and rise through the first connecting rod 54, thereby realizing that the heating plate 51 is away from or close to the water filter cartridge 43, and can be away from the water filter cartridge 43 when the water filter cartridge 43 is filtering materials, and close to the water filter cartridge 43 when drying materials in the water filter cartridge 43, thereby improving the drying effect. Moreover, when the first motor 46 drives the rotating sleeve 45 to rotate, the rotating sleeve 45 drives the water filter cartridge 43 to rotate, and the uniformity of heating the materials can also be improved.

[0049] In this embodiment, in conjunction with the attached Figure 3 It can be seen that the four corners of the partition 41 are slidably arranged on the guide shaft 411 of the connecting plate in the filter box 40, a spring 412 is arranged between the partition 41 and the connecting plate, and a vibration motor 413 is arranged on the partition 41.

[0050] This is a solution proposed to solve the problem that the material is not easy to fall off after being dried and attached to the water filter cartridge 43. When the material is attached to the water filter cartridge 43, the vibration motor 413 drives the partition 41 to vibrate up and down, and the discharge port 42 of the partition 41 is connected to the water filter cartridge 43 through a bearing, and the guide key 432 on the water filter cartridge 43 is matched with the guide groove on the rotating sleeve 45, which can satisfy the requirements that the partition 41 can drive the water filter cartridge 43 to vibrate up and down, and can also make the water filter cartridge 43 rotate when it needs to rotate. Therefore, when the partition 41 vibrates up and down, it drives the water filter cartridge 43 to vibrate, which can effectively shake the material off for recycling. When the partition 41 vibrates, the spring 412 is compressed or relaxed, which can effectively avoid the collision between the partition 41 and the connecting plate, thereby playing a buffering role.
