Description

Technical Field

[0001] The present invention relates to the technical field of stirring equipment, and more specifically, to an intelligent processing device for producing paper products. Background Art

[0002] In the production process of paper products, various prepared fiber raw material slurries need to be added to a stirring device in a predetermined proportion for mixing. After that, the prepared reinforcing agent, sizing agent and other additives are added in sequence. After stirring and mixing through the stirring device, a pulp suspension can be obtained.

[0003] In the production process of high-strength packaging paper, adding longer hemp fibers to enhance the toughness of paper is a key link. However, traditional stirring devices have significant problems in handling this process. The blades of traditional stirring devices are mostly designed in a dispersed manner, which makes it very easy for longer hemp fibers to entangle on the blades. Moreover, during the stirring process, hemp fiber pulp and other fiber slurries are easily adsorbed to each other due to factors such as electrostatic effects and surface tension between fibers, forming fiber agglomerates. This agglomeration phenomenon directly leads to uneven paper strength, causing the packaging paper to easily break during use and unable to meet the expected high strength requirements. In addition, the stirring amplitude of the dispersed stirring blades is large at the initial stage of stirring, and the additives are added downward from the top inlet of the stirring barrel, which causes a large amount of air to be drawn into the slurry, thereby generating foam. If there is too much foam, it will occupy the space of the stirring barrel and affect the effective volume of the slurry. Although the traditional method is to eliminate foam by adding defoamers, excessive use of defoamers not only increases production costs, but also has an adverse effect on the strength of the final paper. Therefore, there is an urgent need for a raw material slurry stirring device that can be used for the production of high-strength packaging paper to solve the problems of fiber agglomeration and foaming and ensure product quality and production efficiency.

The ends of the plurality of connecting sliders away from the paddle blade are slidably connected to the plurality of limiting sliding grooves one by one. The connecting sliders in the plurality of paddle blade assemblies close to the slit are all fixed to the outside of the movable rod.

[0011] As a further optimized solution of the present invention, the additive conveying mechanism includes a storage container, a delivery pump, and a delivery pipeline. The storage container and the delivery pump are both fixedly installed outside the stirring barrel. The input end of the delivery pump is communicated with the bottom of the storage container through a pipeline. The output end of the delivery pump is communicated with one end of the delivery pipeline, and the other end of the delivery pipeline extends from the outside of the storage container to the inside thereof.

[0012] As a further optimized solution of the present invention, the linear driving assembly is an electric push rod. The electric push rod is fixedly installed at the upper end of the outside of the stirring shaft body, and its telescopic end is fixed to the top end of the movable rod.

[0013] As a further optimization scheme of the present invention, the linear drive assembly is a hydraulic drive device, and the hydraulic drive device includes a piston rod, a spray head, an induction switch, a first cavity and a second cavity. The first cavity and the second cavity are both arranged at the lower end inside the stirring shaft body. The upper end of the first cavity communicates with the upper end of the second cavity. The piston rod is slidably installed in the first cavity, and its bottom end slidably penetrates the bottom of the stirring shaft body and then is fixed to the bottom end of the movable rod. The end of the conveying pipeline is rotatably connected to the bottom end of the second cavity. The spray head is installed at the bottom end of the stirring shaft body, and its interior communicates with the second cavity. The induction switch is installed at the bottom of the first cavity. An electronic valve is provided on the spray head, and the induction switch is electrically connected to the electronic valve.

[0014] As a further optimization scheme of the present invention, the number of the paddle blade assemblies is three, and the ratio of the diameter of the stirring barrel to that of the paddle blade is 0.3 - 0.4.

[0015] As a further optimization scheme of the present invention, the included angle between the guiding inclined groove and the top surface of the paddle blade is 30 - 35°, and the depth of the guiding inclined groove is 0.5 - 1 cm.

[0016] As a further optimization scheme of the present invention, a number of linearly evenly distributed protrusions are fixed on one side of the gap, and a number of grooves adapted to the protrusions are provided on the other side of the gap.

The speed - regulating motor is fixedly installed on the top of the mounting frame.

[0019] The beneficial effects of the present invention are as follows:

[0020] The stirring paddle blade mechanism provided by the present invention has two usage forms for the paddle blades. In the initial stage of stirring, the paddle blades present a first form of being flat. At this time, the agitation amplitude of the raw material slurry is small, which can make the surface of the slurry form a stable flow state and effectively reduce the air entrainment. At the same time, the additive conveying mechanism slowly adds the additive to the bottom of the stirring barrel, and the additive flows upward from the bottom of the barrel and is initially mixed with the raw material slurry, further reducing the air entrainment amount. In this way, the generation of foam can be significantly reduced in the initial stage of stirring, solving the problem of a large amount of air entrainment and foam generation caused by the addition of additives and the stirring of the stirring shaft. Since the foam is greatly reduced, the dosage of the defoaming agent used to eliminate the foam is also reduced accordingly, thereby reducing the production cost of the pulp suspension.

[0021] In the middle and late stages of stirring, the blade is switched to the second spiral shape. During the stirring process, the spiral blade can enable the slurry and fibers to form a spiral upward or downward flow path in the stirring barrel. In the area near the barrel wall, the slurry flows upward under the push of the blade; while near the stirring shaft, the liquid flows downward. This complex circulating flow pattern can effectively break fiber agglomeration to solve the problems of fiber raw material agglomeration at local positions and long fiber entanglement.

Detailed Implementation Modes Embodiment

[0030] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein, and changes can be made to the functions and arrangements of the elements discussed without departing from the scope of protection of the content of this specification. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0031] Please refer to Figures 1 to 4 , an intelligent processing device for paper product production, comprising: a stirring barrel 1, a stirring power source 2, a stirring blade mechanism 3, and an additive delivery mechanism 4. Among them, the stirring blade mechanism 3 is arranged in the stirring barrel 1. The stirring blade mechanism 3 includes a stirring shaft body 31, a movable rod 32, a linear drive assembly 33, and three blade assemblies 34. The top end of the stirring shaft body 31 is fixed to the drive end of the stirring power source 2. The movable rod 32 is arranged parallel to the outside of the stirring shaft body 31. The drive end of the linear drive assembly 33 is connected to the end of the movable rod 32, and it is used to drive the movable rod 32 to linearly move relative to the outside of the stirring shaft body 31. The three blade assemblies 34 are evenly distributed along the length direction of the stirring shaft body 31. The blade assembly 34 includes a deformation stretching member and an elastic annular blade 341. The blade 341 can be a stainless steel thin plate, and by performing specific pressing on its surface, it can be deformed according to a preset form.

[0032] Specifically, the diameter ratio of the stirring barrel 1 to the paddle 341 is 0.3 - 0.4. When the paddle 341 within this range rotates, it can minimize the fluctuations generated by the slurry in the initial stage of stirring. The top surface of the paddle 341 is provided with gaps 342 distributed along its radial direction. On one side of the gap 342, four linearly evenly distributed protrusions 348 are fixed. On the other side of the gap 342, four grooves 349 adapted to the protrusions 348 are provided. The four protrusions 348 and the four grooves 349 are slidably docked one by one. When the paddle 341 is in an annular shape, through the cooperation and clamping of the protrusions 348 and the grooves 349, the radial compressive capacity of the paddle 341 can be increased, avoiding large - degree deformation during rotation and affecting its stirring effect. The outer ring surface of the paddle 341 is provided with a number of evenly distributed diversion inclined grooves 343. The included angle between the diversion inclined grooves 343 and the top surface of the paddle 341 is 30 - 35°, and the depth of the diversion inclined grooves 343 is 0.5 - 1 cm. Since the first form of the paddle 341 is flat, the setting of the diversion inclined grooves 343 can guide the slurry to flow smoothly. It can not only enable the paddle 341 to perform preliminary stirring, but also avoid the generation of violent vortices and the entrainment of air, so as to reduce the generation of foam. The deformation stretching member is fixedly installed on the outer side of the stirring shaft body 31. One end of it is connected to the movable rod 32. The paddle 341 is movably sleeved on the outer side of the deformation stretching member. The connection end of the inner ring surface of the paddle 341 and the deformation stretching member is fixed. Through the linear movement of the movable rod 32, the three paddles 341 are synchronously stretched and deformed according to a preset shape to form a complete propeller - shaped paddle 341 structure.

[0033] The stirring power source 2 is used to drive the stirring paddle mechanism 3 to rotate in the stirring barrel 1. The additive delivery mechanism 4 is used to deliver the required additives to the bottom of the stirring barrel 1. By delivering the additives to the bottom of the stirring barrel 1, the additives will gradually rise under their own gravity and be gradually mixed with the slurry already in the stirring barrel 1, which can effectively reduce the entrainment of air and further reduce the generation of foam during stirring.

[0034] It should be noted that when the above intelligent processing device for paper product production is in use, first, the prepared fiber raw material slurries are added into the stirring barrel 1 according to a predetermined ratio, and the additives to be added are added into the additive conveying mechanism 4. Then, the stirring power source 2 is started to rotate at a low speed, which can drive the stirring paddle mechanism 3 to rotate, thereby stirring the raw material slurry in the stirring barrel 1. In the initial stage of stirring, the additives are slowly added to the bottom of the stirring barrel 1 through the additive conveying mechanism 4. Since the paddle 341 is flat, the agitation amplitude of the raw material slurry is small, forming a relatively stable flow on the surface of the slurry, which can reduce the entrainment of air and thus reduce the generation of foam. At the same time, the additives gradually flow upward from the bottom of the stirring barrel 1 and are preliminarily mixed with the raw material slurry. Compared with the traditional method of directly adding from the top of the stirring barrel 1, the entrainment of air is greatly reduced, and the generation of foam in the initial stage of stirring is further reduced. In this way, by utilizing the first use form of the slurry and the conveying method of the additive conveying mechanism 4, the generation of foam can be effectively reduced in the initial stage of stirring, solving the problem of generating a large amount of foam due to the addition of additives and the entrainment of a large amount of air by the stirring shaft. Since the foam is greatly reduced, the amount of defoamer used to eliminate the foam can also be reduced. In this way, the production cost of the pulp suspension is reduced.

[0035] In the middle and late stages of stirring, at this time, the additives have been evenly mixed with the raw material slurry, but the raw material fiber slurries have not been fully mixed. Only relying on the flat paddle 341 for stirring, the stirring effect is not ideal. At this time, it is necessary to switch the paddle 341 to the second use form. When switching, the stirring power source 2 is temporarily turned off, and the linear drive assembly 33 drives the movable rod 32 to move downward along the outer side of the stirring shaft body 31, which can simultaneously drive the three deformation tensile force activities and respectively generate a downward pulling force on the inner ring surface of the paddle 341 connected to it. After the paddle 341 is subjected to the pulling force, it begins to deform and gradually becomes spiral. When the protrusion 348 at the lower end of the paddle 341 is aligned and clamped with the groove 349 at the fixed end of the paddle 341 below it, the linear drive assembly 33 stops driving. The three deformed paddles 341 are spliced to form a complete propeller blade 341 structure, completing the switching of the second form of the paddle 341. After that, the stirring power source 2 is started to rotate at a high speed, thereby driving the stirring paddle mechanism 3 to rotate. When the propeller blade 341 in the second form rotates, it can make the slurry and fibers form a spiral upward or downward flow path in the stirring barrel 1. In the area near the barrel wall, the slurry flows upward under the push of the paddle 341, while near the stirring shaft, the liquid flows downward. This complex circulating flow pattern can effectively break the fiber agglomeration and solve the problem of fiber raw materials agglomerating in local positions.

[0036] Please refer to Figures 3 to 5, the deformation and stretching member includes a bushing 344, a fixing block 345, and seven connecting sliders 346. The bushing 344 is fixedly sleeved on the outer side of the stirring shaft body 31. Seven circumferentially evenly distributed limiting chutes 347 are provided on the outer ring surface of the bushing 344, and the heights of the seven limiting chutes 347 increase in sequence. The fixing block 345 and the seven connecting sliders 346 are evenly and fixedly installed on the inner ring surface of the blade 341, and the fixing block 345 is located at one end of the inner ring surface of the blade 341 close to the gap 342. One end of the fixing block 345 away from the blade 341 is fixed to the outer side of the bushing 344. One end of the seven connecting sliders 346 away from the blade 341 is slidably connected to the seven limiting chutes 347 in one-to-one correspondence. The connecting sliders 346 of the three blade assemblies 34 close to the gap 342 are all fixed to the outer side of the movable rod 32.

[0037] It should be noted that when the deformation and stretching member is in use, by moving the movable rod 32 downward, the three connecting sliders 346 connected thereto can be driven to slide downward along the corresponding limiting chutes 347 first. One end of the blade 341 close to the connecting slider 346 is subjected to a downward pulling force from the connecting slider 346 and starts to deform downward, and then drives the other connecting sliders to slide along the corresponding limiting chutes 347. One end of the blade 341 connected to the fixing block 345 will not move downward due to the fixing effect of the fixing block 345, and the height of each limiting chute 347 is set according to the preset deformation posture of the blade 341. By the cooperation of the connecting sliders 346 at different positions and the corresponding limiting chutes 347, the deformation of the blade 341 can be limited and guided. When the connecting slider 346 connected to the movable rod 32 slides to the bottom wall of the corresponding limiting chute 347, it just makes the blade 341 deform into a preset spiral shape, completing the shape switching of the blade 341. When switching back to the first shape, by controlling the movable rod 32 to move upward, with the help of the elasticity of the blade 341 itself, it can gradually return to the flat shape. In this way, the deformation and stretching member can achieve precise deformation of the blade 341, so that the blade 341 can be automatically and repeatedly deformed stably in a preset manner to meet the usage requirements in different stirring periods.

[0038] Please refer to Figure 2 , the additive delivery mechanism 4 includes a storage container 41, a delivery pump 42, and a delivery pipeline 43. The storage container 41 and the delivery pump 42 are both fixedly installed on the outer side of the stirring barrel 1. The input end of the delivery pump 42 is communicated with the bottom of the storage container 41 through a pipeline, and the output end of the delivery pump 42 is communicated with one end of the delivery pipeline 43. The other end of the delivery pipeline 43 extends from the outer side of the storage container 41 to the inner side thereof.

[0039] It should be noted that when the above additive conveying mechanism 4 is in use, the additive in the storage container 41 is conveyed to the conveying pipeline 43 by the conveying pump 42, and then is conveyed to the bottom of the stirring barrel 1 from the end of the conveying pipeline 43 and sprayed out.

[0040] Please refer to Figure 3 , the linear driving component 33 is an electric push rod 336, and the electric push rod 336 is fixedly installed at the upper end outside the stirring shaft body 31, and its telescopic end is fixedly connected to the top end of the movable rod 32.

[0041] It should be noted that when the linear telescopic driving component is in use, by extending the electric push rod 336, the movable rod 32 can be driven to move downward, and then the movable rod 32 drives the paddle 341 to deform.

[0042] Please refer to Figures 1 to 2 , the stirring power source 2 includes a mounting frame 21 and a speed regulating motor 22. The mounting frame 21 is detachably installed in the middle of the top of the stirring barrel 1. There is a feeding port reserved between both sides of the mounting frame 21 and the bottom of the inner wall of the stirring barrel 1. The speed regulating motor 22 is fixedly installed on the top of the mounting frame 21. Embodiment

[0043] Please refer to Figures 6 to 7 , the difference between the second embodiment and the first embodiment of the present invention is that: the linear driving component 33 is a hydraulic driving device, and the hydraulic driving device includes a piston rod 331, a spray head 332, an induction switch 333, a first cavity 334 and a second cavity 335. Both the first cavity 334 and the second cavity 335 are arranged at the lower end inside the stirring shaft body 31. The upper end of the first cavity 334 is communicated with the upper end of the second cavity 335. The piston rod 331 is slidably installed in the first cavity 334, and its bottom end slidably penetrates through the bottom of the stirring shaft body 31 and is fixedly connected to the bottom end of the movable rod 32. The end of the conveying pipeline 43 is rotatably connected to the bottom end of the second cavity 335. The spray head 332 is installed at the bottom end of the stirring shaft body 31, and its interior is communicated with the second cavity 335. The induction switch 333 is installed at the bottom of the first cavity 334. The spray head 332 is provided with an electronic valve, and the induction switch 333 is electrically connected to the electronic valve.

[0044] It should be noted that when the above hydraulic drive device is in use, first, the additive is transported to the first cavity 334 through the additive transport mechanism 4. Since the nozzle 332 is in a closed state, the additive can gradually flow from the first cavity 334 into the second cavity 335. The additive gradually generates a downward thrust on the piston rod 331, causing the piston rod 331 to drive the movable rod 32 to move downward. When the end of the piston rod 331 moves down to the bottom wall of the first cavity 334 and contacts the proximity switch 333, the proximity switch 333 is triggered to start, causing the nozzle 332 to open. At the same time, the additive transport mechanism 4 is closed, and the stirring power source 2 drives the stirring blade mechanism 3 to rotate. During this process, the additive starts to spray out through the nozzle 332. As the stirring shaft body 31 rotates, the additive can be evenly sprayed out in all directions, so as to accelerate the mixing speed of the additive and the raw material slurry. As the additive is sprayed out, the pressure on the piston rod 331 decreases. When the pressure is less than the deformation force of the blade 341, the blade 341 starts to deform and reset, driving the movable rod 32 to move upward. The piston rod 331 follows the movable rod 32 to move upward together, and gradually pushes the additive to flow from the first cavity 334 to the second cavity 335 until the blade 341 resumes deformation and the piston rod 331 just resets. The additive is also gradually discharged under the rotation of the stirring shaft. In this way, compared with the driving method of the electric push rod 336 in the first embodiment, this hydraulic drive device cooperates with the additive transport mechanism 4 and the stirring shaft body 31, and uses the introduced additive as the power source to synchronously drive the movable rod 32. On the one hand, it realizes the synergistic effect of additive introduction and blade 341 deformation, synchronously controls the deformation degree of the blade 341 according to the additive introduction process, so that the additive and the deformation degree of the blade 341 are synchronously adapted. After the additive introduction is completed, the blade 341 also synchronously completes the deformation switching without the need to set a separate program for regulation. In addition, a separate drive source is added, saving the use of the circuit and control program of the separate drive source, and reducing the power consumption of the stirring blade mechanism 3. On the other hand, it can also make the additive evenly distributed in the stirring tank 1, accelerating the mixing speed of the additive and the slurry.

[0045] The above describes the embodiments of the specific implementation manner, but this embodiment is not limited to the above specific implementation manner. The above specific implementation manner is only illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
