[0031] The present invention will be described in further detail below with reference to the accompanying drawings.

[0032] Combined with attachment Figures 1 to 5 A pulper for tissue production mainly comprises: a tank body 1, a pulping assembly 2, a filter screen 3, a discharge device 4, and a shock absorber 6. A feed pipe 15 is fixedly connected to the upper end of the tank body 1, and both the feed pipe 15 and the discharge pipe 14 are connected to the interior of the tank body 1.

[0033] Then, the pulping component 2 is used to crush the raw materials. The pulping component 2 includes a rotating shaft 9, which is rotatably connected to the upper end of the inner wall of the tank body 1. A number of crushing leaves 10 are fixedly connected on both sides of the rotating shaft 9, and a number of crushing leaves 11 are fixedly connected to the upper and lower ends of the crushing leaves 10. A motor 12 is fixedly connected to the upper end of the tank body 1, and the output shaft of the motor 12 passes through the tank body 1 and extends to the bottom thereof and is fixedly connected to the rotating shaft 9.

[0034] Motor 12 drives the rotating shaft 9 to rotate, driving the crushing blade 10 and the crushing blade 2 11 to rotate, crushing the raw materials in the tank body 1, and the filter screen 3 is fixedly connected to the lower part of the inner wall of the tank body 1. The pulp crushed to a standard size falls below through the filter screen 3. Cleaning plates 13 with brushes are fixedly connected on both sides of the lower end of the rotating shaft 9. The brushes of the cleaning plates 13 are movably connected to the upper end of the filter screen 3. The cleaning plates 13 rotate with the rotating shaft 9. The brushes of the cleaning plates 13 can prevent the filter screen 3 from being blocked.

[0035] Next, the discharging device 4 includes a discharging auger 5, which discharges the crushed slurry from the tank body 1 by rotating the discharging auger 5. The discharging device 4 also includes a discharging pipe 14, which is fixedly connected to the lower part of one side of the tank body 1. The discharging auger 5 is arranged below the filter screen 3. The end of the discharging auger 5 away from the discharging pipe 14 is rotatably connected to the inner wall of the tank body 1, and the end of the discharging auger 5 away from the feeding pipe 15 passes through the tank body 1 and extends into the discharging pipe 14. The front and rear ends of the discharging auger 5 are both provided with guide blocks 16 fixedly connected to the inner wall of the tank body 1, and the front and rear end guide blocks 16 are both provided with inclined surfaces at the ends close to each other.

[0036] In order to provide drive for the discharging auger 5, a motor 2 17 is fixedly connected to the lower part of the tank body 1 away from the discharging pipe 14. The output shaft of the motor 2 17 passes through the tank body 1 and extends to the interior thereof and is fixedly connected to the discharging auger 5. When the pulp falling from the filter screen 3 falls on the guide block 16, it slides onto the discharging auger 5 under the action of the inclined surface. The motor 2 17 drives the discharging auger 5 to discharge the pulp from the discharging pipe 14.

[0037] The shock absorbing device 6 is arranged on both sides below the tank body 1. The shock absorbing device 6 includes a support assembly 7 and two shock absorbing assemblies 8. The support assembly 7 cooperates with the shock absorbing assembly 8 to perform shock absorption and auxiliary support. The shock absorbing assembly 8 is arranged at the front and rear ends of the support assembly 7, and the front and rear end shock absorbing assemblies 8 are symmetrically arranged. The support assembly 7 includes a support rod 18, and the support rod 18 is fixedly connected to the lower end of the tank body 1. A slide groove 19 is opened in the support rod 18, and a support rod 20 is slidably connected in the slide groove 19. Gas damping or friction damping is used between the support rod 18 and the support rod 2, 20 so that the support rod 18 and the support rod 2 change their relative positions while having a certain damping force. This part of the damping force enables the support rod 18 and the support rod 2, 20 to have a certain force to maintain the status quo when they are not retracted. Since the above-mentioned gas damping, friction damping, etc. are common technologies in the existing technology, their technical principles will not be repeated here.

[0038] The lower end of the support rod 20 extends through the slide groove 19 to the bottom thereof and is fixedly connected to the base plate 21. The front and rear ends of the upper end of the base plate 21 are fixedly connected to the fixed plate 22. The shock-absorbing assembly 8 includes a rotating rod 23. The upper end of the rotating rod 23 is hinged to the lower part of the support rod 18. The lower end of the rotating rod 23 is hinged to the slider 24. A fixing rod 25 is fixedly connected between the fixed plate 22 and the support rod 20. The slider 24 is slidably connected to the fixing rod 25. A shock-absorbing spring 26 is passed through the outer periphery of the fixing rod 25. The front and rear end shock-absorbing springs 26 are fixedly connected to the slider 24 and the fixing plate 22 at the ends close to each other and at the ends away from each other respectively.

[0039] When the device is running, the tank body 1 will shake, and then the support rod 18 will slide downward, driving the lower ends of the rotating rods 23 at the front and rear ends to move away from each other, pushing the slider 24 toward the fixed plate 22, and then the shock-absorbing spring 26 is compressed. After the impact is over, the shock-absorbing spring 26 rebounds to buffer the vibration, and then the slider 24 is pushed to reset, and the support rod 18 is reset by the rotating rod 23. With the cooperation of the support rod 20, the support rod 18 and the slide groove 19, the tank body 1 can only move up and down, preventing it from moving to the sides and front and back, thereby increasing the stability of the device.

[0040] After the pulp raw material is poured into the tank body 1 from the feed pipe 15, the motor 12 drives the rotating shaft 9 to rotate, driving the crushing blade 10 and the crushing blade 2 11 to rotate, and the raw material in the tank body 1 is crushed. The filter screen 3 crushes the pulp into a standard size and falls below through the filter screen 3. The cleaning plate 13 rotates with the rotating shaft 9 to clean out the pulp blocked on the filter screen 3. The pulp falling from the filter screen 3 slides into the discharging screw dragon 5. The motor 2 17 drives the discharging screw dragon 5 to rotate and discharge the pulp from the discharging pipe 14. The discharging is fast and the discharging is prevented from being blocked. When the tank body 1 shakes, the support rod 18 slides downward, driving the lower ends of the rotating rods 23 at the front and rear ends to move away from each other, pushing the slider 24 toward the fixed plate 22, and then the shock-absorbing spring 26 is compressed. After the impact is over, the shock-absorbing spring 26 rebounds to cushion the vibration and increase the service life of the device. Finally, the support rod 18 and the slider 24 are reset.

[0041] It should be noted here that the connection between the motor 2 17 and the tank body 1 described in the present invention is connected by a sealed bearing with good sealing performance available on the market. The sealed bearings here can be selected from bearings with sealing performance including but not limited to deep groove ball bearings, outer spherical bearings, stainless steel bearings, etc., and since the above-mentioned bearings all belong to the existing technology, their technical details will not be repeated here.

[0042] It should be noted that the electrical components described herein are all electrically connected to an external controller and 220V mains electricity. The controller can be a conventional, known device such as a computer. Detailed descriptions of known functions and components are omitted from this disclosure.
