The rotation of the first shaft drives the rotation of the first stirring rod, and the slurry is stirred by the first stirring rod. After sufficient stirring, the slurry passes through the first through hole and is further discharged from the discharge port. The slurry may be partially blocked by fibers or impurities in the process of passing through the first through hole. By setting the beating drum along the depth direction of the beating drum, the beating drum is vibrated in the depth direction of the beating drum, thereby shaking off the fibers or impurities blocked in the first through hole, without affecting the discharge of the slurry.

[0008] Optionally, a plurality of stirring teeth are fixedly connected to the first stirring rod.

[0009] By adopting the above technical solution, in order to further improve the quality of the forming paper, a plurality of stirring teeth are fixedly connected to each first stirring rod, so that the stirring teeth can increase the shear force of the fibers in the pulp to break up the fiber bundles and improve the quality of the paper.

[0010] Optionally, the stirring assembly also includes a second stirring rod, and a plurality of the second stirring rods are arranged at intervals along the circumferential direction of the first rotating shaft. The second stirring rod is arranged on the side of the first stirring rod close to the bottom wall of the beating cylinder, and the second stirring rod is slidably connected to the first rotating shaft along the depth direction of the beating cylinder.

[0011] By adopting the above technical solution, by setting a second stirring rod, the second stirring rod slides along the depth direction of the beating drum, the first stirring rod rotates, and the second stirring rod slides, the first stirring rod and the second stirring rod realize stirring in two directions in the beating drum, further improving the degree of sufficient stirring of the slurry.

[0012] Optionally, the stirring assembly further includes a collar, which is sleeved on the first rotating shaft, one end of the second stirring rod is fixedly connected to the collar, the first rotating shaft is provided with a thread on the collar, and the collar slides along the length direction of the first rotating shaft.

[0013] By adopting the above technical solution, by setting the collar, the first shaft is provided with a thread at the collar. When the first shaft rotates, the collar is driven to slide along the length direction of the first shaft, and further drives the second stirring rod to slide.

[0014] Optionally, a limiting component is further included, which is located in the beating barrel. The limiting component includes a limiting ring and a first elastic member. The limiting ring is sleeved on the first rotating shaft and fixedly connected to the bottom wall of the beating barrel. The limiting ring is located at a position where the first rotating shaft is not provided with threads. The first elastic member is sleeved on the first rotating shaft. The extension and contraction direction of the first elastic member is parallel to the depth direction of the beating barrel. The first elastic member is fixedly connected between the limiting ring and the sleeve.

[0015] By adopting the above technical solution and setting a limiting assembly, when the collar slides along the length direction of the first rotating shaft, the first elastic member is compressed, and the limiting ring and the first elastic member limit the sliding of the collar.

[0016] Optionally, it also includes a sliding component, which is located within the body. The sliding component includes a first mounting seat and a telescopic rod. The first mounting seat is fixedly connected to the side wall of the body. The telescopic rod is parallel to the depth direction of the beating cylinder. Multiple telescopic rods are arranged at intervals along the circumferential direction of the beating cylinder. The fixed section of the telescopic rod is fixedly connected to the first mounting seat, and the end of the movable section away from the fixed section is directly or indirectly fixedly connected to the beating cylinder. The fixed section of the telescopic rod and the end of the movable section close to each other are slidably connected.

[0017] By adopting the above technical solution and setting a telescopic rod, when the slurry enters the beating drum, under the common gravity of the slurry and the beating drum, the telescopic section of the telescopic rod slides toward the side close to the fixed section. When an external force acts on the bottom wall of the beating drum, due to the telescopic effect of the telescopic rod, the beating drum will slide in the depth direction of the drum itself.

[0018] Optionally, the sliding assembly also includes a second elastic member, which is sleeved on the telescopic rod, the telescopic direction of the second elastic member is parallel to the depth direction of the beating cylinder, and the second elastic member is fixedly connected between the first mounting seat and the beating cylinder. The second elastic member has the force to drive the beating cylinder to move away from the bottom wall of the machine body under recoverable deformation.

[0019] By adopting the above technical solution, by setting a second elastic member, under the action of the second elastic member, when the slurry enters the beating drum, the second elastic member is compressed due to the gravity of the slurry and the weight of the beating drum itself. When the slurry decreases, the second elastic member changes from a compressed state to a normal state. By setting the second elastic member, the beating drum can be reset.

[0020] Optionally, it also includes a first drive component, which is arranged in the body and located on the side of the beating cylinder close to the bottom wall of the body. The first drive component includes a second rotating shaft, a first bevel gear, a second bevel gear and a cam. The second rotating shaft is perpendicular to the depth direction of the beating cylinder. The second rotating shaft is rotatably connected to the body.

The first bevel gear and the second bevel gear are meshed. The second rotating shaft is fixedly sleeved with a cam, and the raised part of the cam is in contact with the bottom wall of the beating cylinder.

[0021] By adopting the above technical solution, by setting up the first driving component, when the first shaft rotates, the second shaft is further driven to rotate through the first bevel gear and the second bevel gear, and the cam is further driven to rotate. When the cam rotates, the raised part of the cam contacts the bottom wall of the beating cylinder, which will drive the beating cylinder to slide along its own depth direction toward the side close to the cover plate, thereby causing the beating cylinder to vibrate in the vertical direction, further shaking off the fibers or impurities blocked in the first through hole.

[0022] Optionally, a discharge assembly is further included, wherein the discharge assembly includes a discharge pipe, and one end of the discharge pipe is connected to the discharge port.

[0023] By adopting the above technical solution and providing a discharge pipe, the slurry is discharged from the first through hole and further discharged from the discharge pipe.

The return pipe is connected to a water pump, and the discharge pipe is connected to a valve, which is located downstream of the connection point between the discharge pipe and the return pipe.

[0025] By adopting the above technical solution and setting up a reflux pipe, when the slurry meets the processing standards, the valve is opened to discharge the slurry from the discharge pipe. When the slurry needs to be circulated and stirred again, the valve is closed and the water pump is turned on, and the slurry further enters the beating drum through the discharge pipe and the reflux pipe.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The present application provides a beating drum and a stirring assembly.

A plurality of first through holes 21 are provided through the beating drum 2; the slurry is transported to the beating drum 2 through the feed pipe 112, and the slurry is stirred in the beating drum 2. After sufficient stirring, the slurry passes through the first through hole 21 and is further discharged from the discharge port 12. The slurry may be partially blocked by fibers or impurities in the process of passing through the first through hole 21. By arranging the beating drum 2 along the depth direction of the beating drum 2, the beating drum 2 is vibrated in the depth direction of the beating drum 2, thereby shaking off the fibers or impurities blocked in the first through hole 21, without affecting the discharge of the slurry.

[0030] Reference Figure 2 In order to fully stir the slurry, the linked circulation beater for papermaking also includes a stirring assembly 3, which includes a first rotating shaft 31 and a first stirring rod 32.

The first stirring rod 32 is perpendicular to the depth direction of the beating barrel 2. A plurality of first stirring rods 32 are arranged at intervals along the circumference of the first rotating shaft 31. The rotation of the first rotating shaft 31 drives the first stirring rod 32 to rotate, so that the slurry is fully stirred by the plurality of first stirring rods 32.

[0031] Reference Figure 1 and Figure 2 In this embodiment, the machine body 1 and the beating drum 2 are both cylindrical structures; in order to drive the first rotating shaft to rotate, the stirring assembly 3 also includes a motor 33, the motor 33 casing is fixedly connected to the bottom wall of the machine body 1, and the output shaft of the motor 33 is coaxially fixedly connected to the first rotating shaft 31. The motor 33 drives the first rotating shaft 31 to rotate. In order to support the machine body 1, a support frame 13 is fixedly connected to the bottom wall of the machine body 1.

[0032] Reference Figure 2In order to further improve the quality of the formed paper, a plurality of stirring teeth 321 are fixedly connected to each first stirring rod 32. The plurality of stirring teeth 321 are distributed along the length of the first stirring rod 32. In this embodiment, the stirring teeth 321 are conical, and the outer diameter of the stirring teeth 321 gradually decreases along the side away from the first stirring rod 32. The stirring teeth 321 increase the shear force of the fibers in the pulp, thereby breaking up the fiber bundles and improving the quality of the paper.

[0033] Reference Figure 3 In order to further improve the uniformity of slurry stirring, the stirring assembly 3 also includes a second stirring rod 34. A plurality of second stirring rods 34 are arranged at intervals along the circumferential direction of the first rotating shaft 31. The second stirring rod 34 is perpendicular to the depth direction of the beating barrel 2. The second stirring rod 34 is arranged on the side of the first stirring rod 32 close to the bottom wall of the beating barrel 2. The second stirring rod 34 is connected to the first rotating shaft 31 by sliding along the depth direction of the beating barrel 2. The second stirring rod 34 slides along the depth direction of the beating barrel 2, so that the slurry in the beating barrel 2 is stirred vertically, thereby further improving the uniformity of the slurry.

[0034] Reference Figure 3 Furthermore, in order to drive the second stirring rod 34 to slide along the depth direction of the beating drum 2, the stirring assembly 3 also includes a collar 35, which is sleeved on the first rotating shaft 31, and one end of the second stirring rod 34 is fixedly connected to the collar 35. The first rotating shaft 31 is provided with a thread at the collar 35, and the collar 35 slides along the axial direction of the first rotating shaft 31. The first rotating shaft 31 rotates, driving the collar 35 to slide at the threaded position.

[0035] Reference Figure 3 In order to guide the sliding of the second stirring rod 34 along the first rotating shaft 31, the papermaking linked circulation beater also includes a guide rod 4, which is parallel to the first rotating shaft 31, and one end of the guide rod 4 is directly or indirectly fixedly connected to the bottom wall of the beating cylinder 2, and the ring 35 is sleeved on the guide rod 4 and slides along the length direction of the guide rod 4, and the guide rod 4 guides the sliding of the ring 35 along the depth direction of the beating cylinder 2.

[0036] Reference Figure 3Since the beating cylinder 2 also needs to slide along the depth direction of the beating cylinder 2, it is necessary to limit the sliding of the second stirring rod 34 along the depth direction of the beating cylinder 2. For this purpose, the papermaking linked circulation beater also includes a limiting component 5. The limiting component 5 includes a limiting ring 51 and a first elastic member 52. The limiting ring 51 is sleeved on the first rotating shaft 31 and fixedly connected to the bottom wall of the beating cylinder 2. The limiting ring 51 is provided at the place where the first rotating shaft 31 is not provided with a thread. The first elastic member 52 is sleeved on the first rotating shaft 31 and fixedly connected. Connected between the collar 35 and the limiting ring 51, the extension and contraction direction of the first elastic member 52 is parallel to the depth direction of the beating cylinder 2, and one end of the guide rod 4 is fixedly connected to the top wall of the limiting ring 51. In this embodiment, the first elastic member 52 is a compression spring. When the first rotating shaft 31 rotates, the collar 35 slides along the depth direction of the beating cylinder 2 toward the side close to the limiting ring 51, and the first elastic member 52 is in a compressed state. The limiting ring 51 and the first elastic member 52 limit the sliding of the collar 35 along the depth direction of the beating cylinder 2.

[0037] Reference Figure 4 and Figure 5 In order to make the beating cylinder 2 slide along its own depth direction, the linked circulation beater for papermaking also includes a sliding assembly 6, which is located in the machine body 1. The sliding assembly 6 includes a first mounting seat 61, a telescopic rod 62 and a second mounting seat 63. The first mounting seat 61 is fixedly connected to the side wall of the machine body 1, and the second mounting seat 63 is fixedly connected to the side wall of the beating cylinder 2. The telescopic rod 62 is parallel to the first direction, and multiple telescopic rods 62 are arranged at intervals along the circumferential direction of the beating cylinder 2. The fixed section of the telescopic rod 62 is fixedly connected to the first mounting seat 61, and the end of the movable section away from the fixed section is fixedly connected to the second mounting seat 63. The fixed section and the movable section of the telescopic rod 62 are close to each other and are slidably connected. By setting the telescopic rod 62, the beating cylinder 2 can slide along its own depth direction.

[0038] Reference Figure 5 In order to enable the beating tube 2 to reset when it slides, the sliding assembly 6 also includes a second elastic member 64, which is sleeved on the telescopic rod 62. The telescopic direction of the second elastic member 64 is parallel to the depth direction of the beating tube 2. The second elastic member 64 is fixedly connected between the first mounting seat 61 and the first mounting seat 63. The second elastic member 64 has the force to drive the beating tube 2 to move toward the side away from the bottom wall of the body 1 under recoverable deformation. Under the action of the second elastic member 64, when the slurry enters the beating tube 2, the second elastic member 64 is compressed due to the gravity of the slurry and the weight of the beating tube 2 itself. When the slurry decreases, the second elastic member 64 changes from a compressed state to a normal state. By setting the second elastic member 64, the beating tube 2 can be reset.

[0039] Reference Figure 6In the beating process, in order to drive the beating cylinder 2 to slide along its own depth direction, the papermaking linked circulation beater also includes a first drive assembly 7, which is arranged in the machine body 1 and is located on the side of the beating cylinder 2 close to the bottom wall of the machine body 1. The first drive assembly 7 includes a second rotating shaft 71, a first bevel gear 72, a second bevel gear 73 and a cam 74. The second rotating shaft 71 is perpendicular to the first rotating shaft 31. The second rotating shaft 71 is provided with two and is located on both sides of the first rotating shaft 31. The second rotating shaft 71 is rotatably connected to the machine body 1. The first rotating shaft 31 is fixedly sleeved with the first bevel gear 72, and each second rotating shaft 71 is fixedly sleeved with a second bevel gear 73. The first bevel gear 72 and the second bevel gear 73 are meshed, and a cam 74 is fixedly sleeved on each second rotating shaft 71. The raised part of the cam 74 contacts the bottom wall of the beating cylinder 2. When the motor 33 drives the first rotating shaft 31 to rotate, the second rotating shaft 71 is further driven to rotate through the first bevel gear 72 and the second bevel gear 73, and the cam 74 is further driven to rotate. When the cam 74 rotates, the raised part of the cam 74 contacts the bottom wall of the beating cylinder 2, which will drive the beating cylinder 2 to slide along its own depth direction toward the side close to the cover plate 11, thereby causing the beating cylinder 2 to vibrate in the vertical direction, further shaking off the fibers or impurities blocked in the first through hole 21.

[0040] Reference Figure 6 It should be noted that when the cam 74 rotates to the raised portion to lift the beating drum 2, the limiting ring 51 is still in contact with the unthreaded portion of the first rotating shaft 31.

[0041] Reference Figure 7 In order to discharge the stirred slurry, the papermaking linked circulation beater also includes a discharge component 8, the discharge component 8 includes a discharge pipe 81, one end of the discharge pipe 81 is connected to the discharge port 12, and the slurry is discharged from the first through hole 21 and further discharged from the discharge pipe 81.

[0042] Reference Figure 7 Since the slurry cannot meet the processing requirements after being stirred once, it needs to be stirred multiple times to meet the processing requirements. In order to circulate and stir the slurry multiple times, the discharge assembly 8 also includes a return pipe 82. One end of the return pipe 82 is fixedly connected to the discharge pipe 81, and the other end is connected to the top wall of the cover plate 11. The end of the return pipe 81 close to the cover plate 11 is located above the beating barrel 2. The return pipe 82 is connected to a water pump 821, and the discharge pipe 81 is connected to a valve 811. The valve 811 is located downstream of the connection between the discharge pipe 81 and the return pipe 82; when the slurry meets the processing standards, the valve 811 is opened to discharge the slurry from the discharge pipe 81. When the slurry needs to be circulated and stirred again, the valve 811 is closed, the water pump 821 is turned on, and the slurry further enters the beating barrel 2 from the discharge pipe 81 and the return pipe 82.

[0043] The implementation principle of the linked circulation beater for papermaking in the embodiment of the present application is as follows: during operation, the slurry is fed into the beating drum 2 through the feed pipe 112, and the motor 33 is started to drive the first rotating shaft 31 to rotate, thereby driving the first stirring rod 32 to rotate and driving the second stirring rod 34 to slide along the depth direction of the beating drum 2. The first stirring rod 32 and the second stirring rod 34 are used to stir the slurry in the horizontal and vertical directions to improve the uniformity of stirring; The first rotating shaft 31 rotates, driving the second rotating shaft 71 to rotate through the first bevel gear 72 and the second bevel gear 73, and further driving the cam 74 to rotate. When the cam 74 rotates, the raised part of the cam 74 contacts the bottom wall of the beating cylinder 2, which will drive the beating cylinder 2 to slide along its own depth direction toward the side close to the cover plate 11, thereby causing the beating cylinder 2 to vibrate in the vertical direction, further shaking off the fibers or impurities blocked in the first through hole 21.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application.
