Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] It should be noted that the terms "front", "rear", "left", "right", "upper", and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0020] Refer to Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 7 , a pulping device for pulp molding production provided in this embodiment includes: Pulping cylinder 1; Crushing cylinder 2, located inside the pulping cylinder 1 and rotatably provided on the top wall of the pulping cylinder 1. A crushing shaft 4 is rotatably provided on the bottom wall of the crushing cylinder 2. Crushing knives are provided on the crushing shaft 4. The waste paper inside the crushing cylinder 2 is crushed by the arrangement of the crushing knives. The crushing cylinder 2 is a mesh cylinder. By the rotation of the crushing cylinder 2, the pulp obtained inside the crushing cylinder 2 is thrown out by centrifugal force, improving the screening efficiency of the obtained pulp; Drive shaft 3, passing through and slidably provided on the bottom wall of the pulping cylinder 1. The drive shaft 3 is configured to be rotatably provided inside the pulping cylinder 1. The drive shaft 3 is coaxially connected to the crushing shaft 4. The drive shaft 3 is used to drive the crushing shaft 4 to rotate inside the crushing cylinder; The cleaning shaft 5 is configured to be driven by the driving shaft 3 to rotate and is arranged on the bottom wall of the pulping cylinder 1. A first lifting groove 7 is formed in the cleaning shaft 5, and the driving shaft 3 penetrates and is slidably arranged in the first lifting groove 7 of the cleaning shaft 5; Wherein, the inner diameter of the upper part of the first lifting groove 7 is smaller than that of the lower part. A first positioning groove 9 is formed on the side wall of the upper part of the first lifting groove 7, and a first positioning protrusion 8 is arranged on the side wall of the driving shaft 3. When the driving shaft 3 slides up to the top of the first lifting groove 7, the first positioning protrusion 8 is completely engaged in the first positioning groove 9, and the driving shaft 3 drives the cleaning shaft 5 to rotate. When the driving shaft 3 does not rise and is located in the upper part of the first lifting groove 7, the first positioning protrusion 8 cannot be engaged in the first positioning groove 9. At this time, there is no connection relationship between the driving shaft 3 and the cleaning shaft 5, and the driving shaft 3 cannot drive the cleaning shaft 5 to rotate.

[0021] During operation, when the driving shaft 3 does not rise along the first lifting groove 7, due to the lack of cooperation between the first positioning protrusion 8 and the first positioning groove 9, the driving shaft 3 cannot drive the cleaning shaft 5 to rotate when it rotates, which can reduce the energy consumption when the driving shaft 3 rotates; when the driving shaft 3 rises to the top of the first lifting groove 7, the first positioning protrusion 8 and the first positioning groove 9 are engaged and matched. At this time, the through hole 11 of the driving shaft 3 and the cleaning shaft 5 are corresponding, and the water delivery channel 10 is communicated with the inside of the cleaning pipe 31 through the through hole 11. At this time, the driving shaft 3 can drive the cleaning shaft 5 and the cleaning pipe 31 to rotate. At this time, if water is delivered into the cleaning pipe 31 through the water delivery channel 10, the water flow will spray out from the cleaning spray holes 6 to clean the side walls of the pulping cylinder 1 and the crushing cylinder 2.

[0022] Specifically, refer to Figure 6 and Figure 7 In this embodiment, a second lifting groove 12 is formed at the lower end of the crushing shaft 4. The driving shaft 3 is configured to be slidably arranged at the upper end in the second lifting groove 12.

The driving shaft 3 is rotatably arranged on the pushing plate 16. Under the driving action of the pushing cylinder 15, the driving shaft 3 is pushed by the pushing plate 16 to slide along the bottom wall of the pulping cylinder 1, driving the driving shaft 3 to slide up and down in the first lifting groove 7 and the second lifting groove 12, so as to realize the adjustment of the connection state between the driving shaft 3 and the cleaning shaft 5.

[0024] Specifically, referring to Figure 3 and Figure 4 , in this embodiment, a rotation driving mechanism is fixedly arranged on the bottom wall of the pulping cylinder 1; The rotation driving mechanism includes: A rotation motor 17, fixedly arranged on the bottom wall of the pulping cylinder 1; A rotation driving gear 18, fixedly arranged on the output shaft of the rotation motor 17; A rotation driven gear 19, fixedly arranged on the driving shaft 3; Wherein, the rotation driven gear 19 meshes with the rotation driving gear 18. The thickness of the rotation driving gear 18 is greater than that of the rotation driven gear 19, and the rotation driven gear 19 slides relative to the rotation driving gear 18.

[0025] During operation, the rotation motor 17 drives the rotation driving gear 18 to rotate. The driving shaft 3 is driven to rotate through the meshing of the rotation driving gear 18 and the rotation driven gear 19. And under the action of the pushing cylinder 15, the driving shaft 3 and the rotation driven gear 19 can be pushed to rise. When the first positioning protrusion 8 and the first positioning groove 9 are engaged, the driving shaft 3 can drive the cleaning shaft 5 to rotate.

[0026] Specifically, referring to Figure 5 and Figure 8 , in this embodiment, a feeding cylinder 20 is arranged on the top wall of the crushing cylinder 2. The feeding cylinder 20 is rotatably arranged through the top wall of the pulping cylinder 1. A screening driving mechanism is arranged on the top wall of the pulping cylinder 1.

[0027] During operation, the screening motor 21 drives the screening driving gear 22 to rotate. The feeding cylinder 20 is driven to rotate through the meshing of the screening driving gear 22 and the screening driven gear 23, thereby driving the crushing cylinder 2 to rotate. The pulp obtained by the crushing of the crushing knife is thrown out when the crushing cylinder 2 rotates, realizing the efficient screening of the pulp.

[0028] It should be noted that a protective shell needs to be provided on the top wall of the pulping cylinder 1, and the screening drive mechanism is arranged inside the protective shell. The protective shell plays a protective role for the screening drive mechanism. A guide pipe 30 is fixedly arranged on the top wall of the protective shell, and the lower end of the guide pipe 30 extends into the feeding cylinder 20, and the feeding cylinder 20 rotates relative to the guide pipe 30.

[0029] Specifically, referring to Figure 3 and Figure 8 , in this embodiment, a high-pressure air gun 24 is provided on the side wall of the pulping cylinder 1. The high-pressure air gun 24 is externally connected to an air pump 25 through an air pipe. The high-pressure air gun 24 is oriented towards the crushing cylinder 2, and the incompletely crushed waste paper adhering to the side wall of the crushing cylinder 2 is cleaned under the action of the high-pressure air gun 24 to ensure the pulping and screening efficiency.

[0030] Specifically, referring to Figure 3 and Figure 4 , in this embodiment, the drive shaft 3 is externally connected to a high-pressure water pump 27 through a water pipe 26. The drive shaft 3 is rotatably connected to the water pipe 26, that is, the water pipe 26 does not rotate synchronously with the drive shaft 3. Under the action of the high-pressure water pump 27, water is conveyed into the water conveyance channel 10 and the cleaning pipe 31 to clean the side walls of the pulping cylinder 1 and the crushing cylinder 2.

[0031] Specifically, referring to Figure 4 and Figure 6 , in this embodiment, a cleaning pipe 31 is connected to the cleaning shaft 5. A plurality of cleaning spray holes 6 are provided on the cleaning pipe 31, and the cleaning spray holes 6 are used to clean the side walls of the pulping cylinder 1 and the crushing cylinder 2; A water conveyance channel 10 is provided inside the drive shaft 3. Through holes 11 are respectively penetrated through the side wall of the first lifting groove 7 and the first positioning protrusion 8. The through hole 11 in the first lifting groove 7 communicates with the first positioning groove 9, and the through hole 11 on the first positioning protrusion 8 communicates with the water conveyance channel 10. When the drive shaft 3 rises to the top of the first lifting groove 7 and the first positioning protrusion 8 is completely engaged in the first positioning groove 9, the through holes 11 in the upper part of the first lifting groove 7 and the side wall of the drive shaft 3 are corresponding and communicate, and the water conveyance channel 10 communicates with the cleaning pipe 31 through the through hole 11; The cleaning pipe 31 is provided with at least two groups in the circumferential direction of the cleaning shaft 5, and the cleaning spray holes 6 of two or more groups of cleaning pipes 31 are arranged in a staggered manner. Different positions on the side walls of the pulping cylinder 1 and the crushing cylinder 2 can be cleaned through the staggered cleaning spray holes 6.

[0032] Specifically, referring to Figure 2 , in this embodiment, a discharge pipe 28 is opened on the bottom wall of the pulping cylinder 1. A valve is provided on the discharge pipe 28. The opening and closing of the discharge pipe 28 can be controlled through the setting of the valve. When the valve of the discharge pipe 28 is opened, the pulp in the pulping cylinder 1 is discharged.

[0033] Specifically, referring to Figure 4 and Figure 8 , in this embodiment, a scraper 29 is fixedly connected to the cleaning shaft. The scraper 29 is arranged in contact with the bottom wall of the pulping cylinder 1. When the cleaning shaft rotates, the scraper 29 scrapes the bottom wall of the pulping cylinder 1 to scrape out the prepared pulp from the discharge pipe 28.

[0034] For a pulping device used in pulp molding production provided in this embodiment, in the initial state, the first positioning protrusion 8 is not engaged in the first positioning groove 9, that is, the driving shaft 3 cannot drive the cleaning shaft 5 to rotate, so as to reduce the energy consumption driven by the driving shaft 3.

[0035] Its working principle is as follows: (1) The cut waste paper is conveyed to the crushing cylinder 2 through the guide pipe 30 with water (biological enzymes and other preparations can also be added to improve the pulping efficiency), and the rotating motor 17 and the screening motor 21 are started; The rotating motor 17 drives the rotating driving gear 18 to rotate. Through the meshing of the rotating driving gear 18 and the rotating driven gear 19, the driving shaft 3 is driven to rotate. Through the cooperation of the second positioning protrusion 13 and the second positioning groove 14, the driving shaft 3 drives the crushing shaft 4 to rotate, and the crushing shaft 4 drives the crushing knife to cut the waste paper; The screening motor 21 drives the screening driving gear 22 to rotate. Through the meshing of the screening driving gear 22 and the screening driven gear 23, the feeding cylinder 20 is driven to rotate. The feeding cylinder 20 drives the crushing cylinder 2 to rotate. When the crushing cylinder 2 rotates, a centrifugal force is generated, and under the action of the centrifugal force, the prepared pulp is thrown out of the crushing cylinder 2.

[0036] (2) Every once in a while, the air pump 25 is started, and high-pressure air is sprayed into the crushing cylinder 2 through the high-pressure air gun 24. The high-pressure air blows the waste paper adhered to the side wall of the crushing cylinder 2 back into the crushing cylinder 2, avoiding incomplete pulping of the waste paper adhered to the side wall of the crushing cylinder 2 and improving the screening efficiency of the pulp.

[0037] (3) After the pulping is completed, the screening motor 21 stops working. Under the action of the pushing cylinder 15, the driving shaft 3 is lifted by the pushing plate 16. When the first positioning protrusion 8 is completely engaged in the first positioning groove 9, the lifting of the driving shaft 3 is completed. At this time, the driving shaft 3 is connected to the cleaning shaft 5 through the cooperation of the first positioning protrusion 8 and the first positioning groove 9, and the water delivery pipe 26 communicates with the inside of the cleaning pipe 31 through the through hole 11.

[0038] (4) Driven by the rotating motor 17, the scraper 29 rotates, and the scraper 29 pushes all the pulp in the pulping cylinder 1 to the discharge pipe 28 to complete the discharging; after the discharging is completed, the high-pressure water pump 27 is started, and the water flows through the water delivery channel 10, the through hole 11, and the cleaning pipe 31 and is sprayed out from the cleaning spray holes 6. And with the rotation of the cleaning shaft 5, the circumference of the crushing cylinder 2 is cleaned. A small amount of pulp remaining on the side wall of the crushing cylinder 2 is sprayed back into the crushing cylinder 2, completely crushed by the crushing knife, and then falls from the bottom wall of the crushing cylinder 2 into the pulping cylinder 1, and flows out from the discharge pipe 28 along with the scraper 29 and the water flow, completing the cleaning of the inner wall of the pulping cylinder 1 and the side wall of the crushing cylinder 2.

[0039] It should be noted that, to improve the crushing efficiency, the rotating directions of the rotating motor 17 and the screening motor 21 are opposite.

[0040] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, material or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, material or device.
