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.

[0011] As a further optimization scheme of the present invention, the additive delivery mechanism includes a storage container, a delivery pump and a delivery pipeline.

The input end of the delivery pump is connected to the bottom of the storage container through a pipeline, and the output end of the delivery pump is connected to one end of the delivery pipeline. The other end of the delivery pipeline extends from the outside of the storage container to the inside thereof.

[0012] As a further optimization solution of the present invention, the linear drive component is an electric push rod, which is fixedly mounted on the upper end of the outer side of the stirring shaft body, and its telescopic end is fixed to the top end of the movable rod.

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

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

[0021] In the middle and late stages of stirring, the blades are switched to the second spiral form. During the stirring process, the spiral blades can make the slurry and fibers form a spiral upward or downward flow path in the stirring barrel. In the area close to the barrel wall, the slurry flows upward under the push of the blades; while near the stirring shaft, the liquid flows downward. This complex circulation flow pattern can effectively break up the fiber agglomeration to solve the problem of local agglomeration of fiber raw materials and entanglement of long fibers.

DETAILED DESCRIPTION

[0030] Embodiment 1

[0031] 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 implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0032] 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, and the stirring blade mechanism 3 includes a stirring shaft 31, a movable rod 32, a linear drive assembly 33 and three blade assemblies 34. The top of the stirring shaft 31 is fixed to the driving end of the stirring power source 2, and the movable rod 32 is arranged parallel to the outside of the stirring shaft 31. The driving end of the linear drive assembly 33 is connected to the end of the movable rod 32, which is used to drive the movable rod 32 to move linearly relative to the outside of the stirring shaft 31; the three blade assemblies 34 are evenly distributed along the length direction of the stirring shaft 31, and the blade assembly 34 includes a deformation stretching member and an elastic annular blade 341. The blade 341 can be a stainless steel sheet, and by pressing its surface specifically, it can be deformed according to a preset shape.

[0033] Specifically, the diameter ratio of the mixing barrel 1 to the blade 341 is 0.3-0.4. When the blade 341 rotates within this range, the fluctuation of the slurry generated in the initial stage of stirring can be minimized. The top surface of the blade 341 is provided with a gap 342 distributed along its radial direction, and four linearly evenly distributed protrusions 348 are fixed on one side of the gap 342. Four grooves 349 adapted to the protrusions 348 are provided on the other side of the gap 342. The four protrusions 348 and the four grooves 349 are slidably docked one by one. When the blade 341 is in a circular ring shape, the protrusions 348 and the grooves 349 are engaged and snapped together, which can increase the radial pressure resistance of the blade 341 and avoid a large degree of deformation during rotation, which affects its stirring effect. The outer annular surface of the blade 341 is provided with a number of evenly distributed guide grooves 343, the angle between the guide grooves 343 and the top surface of the blade 341 is 30-35°, and the depth of the guide grooves 343 is 0.5-1cm. Since the first form of the blade 341 is flat, the guide grooves 343 can guide the slurry to flow smoothly, which can not only make the blade 341 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 outside of the stirring shaft body 31, and one end of it is connected to the linear drive assembly 33. The blade 341 is movably sleeved on the outside of the deformation stretching member, and the inner annular surface of the blade 341 is fixed to the connecting end of the deformation stretching member. Through the linear movement of the movable rod 32, the three blades 341 are stretched synchronously, and deformed according to the preset shape, and spliced ​​to form a complete propeller blade 341 structure.

[0034] The stirring power source 2 is used to drive the stirring blade mechanism 3 to rotate in the stirring barrel 1, and 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 the action of their own gravity and gradually mix with the slurry already in the stirring barrel 1, which can effectively reduce the air being drawn in and further reduce the generation of foam during the stirring process.

[0035] It should be noted that when the above-mentioned intelligent processing device for paper product production is used, the prepared fiber raw material slurry is first added into the stirring barrel 1 according to a predetermined ratio, the additives to be added are added into the additive conveying mechanism 4, the stirring power source 2 is started to rotate at a low speed, and the stirring blade mechanism 3 can be driven to rotate, thereby stirring the raw material slurry in the stirring barrel 1. In the initial stage of stirring, the additive is slowly added to the bottom of the stirring barrel 1 through the additive conveying mechanism 4. Since the blade 341 is in a flat shape, the stirring amplitude of the raw material slurry is small, so that the slurry surface forms a relatively stable flow, which can reduce air entrainment, thereby reducing Less foam is generated, and at the same time, the additive gradually flows upward from the bottom of the stirring barrel 1 and is preliminarily mixed with the raw material slurry. Compared with the traditional method of adding directly from the top of the stirring barrel 1, the air involvement is greatly reduced, and the foam generation in the initial stage of stirring is further reduced. In this way, by utilizing the first use form of the slurry and cooperating with the conveying method of the additive conveying mechanism 4, the foam generation can be effectively reduced in the initial stage of stirring, and the problem of a large amount of foam generated due to the addition of additives and the involvement of a large amount of air in the stirring of the stirring shaft is solved. Since the foam is greatly reduced, the amount of defoaming agent used to eliminate the foam can also be reduced, thereby reducing the production cost of the pulp suspension.

[0036] In the middle and late stages of stirring, the additives have been evenly mixed with the raw material slurry, but the raw material fiber slurries have not been fully mixed. The stirring effect is not ideal if the flat blade 341 is used alone. At this time, the blade 341 needs to be switched to the second use mode. When switching, the stirring power source 2 is temporarily turned off, and the movable rod 32 is driven by the linear drive component 33 to move downward along the outer side of the stirring shaft body 31, which can simultaneously drive the three deformation stretching forces to move and respectively generate downward pulling forces on the inner annular surface of the blade 341 connected thereto. After the blade 341 is subjected to the pulling force, it begins to deform, causing it to gradually deform into a spiral shape. When the protrusion 348 at the lower end of the blade 341 is connected to the groove 348 at the fixed end of the blade 341 below it, the protrusion 348 at the lower end of the blade 341 is connected to the groove 348 at the fixed end of the blade 341 below it. 49 After alignment and snap-fitting, the linear drive assembly 33 stops driving, and the three deformed blades 341 are spliced ​​to form a complete propeller blade 341 structure, completing the switching of the blade 341 to the second form. Afterwards, the stirring power source 2 is started to make it start to rotate at high speed, thereby driving the stirring blade mechanism 3 to rotate. When the propeller blade 341 in the second form rotates, the slurry and fiber can form a spiral upward or downward flow path in the stirring barrel 1. In the area close to the barrel wall, the slurry flows upward under the push of the blade 341, while near the stirring shaft, the liquid flows downward. This complex circulation flow pattern can effectively break up the fiber agglomeration and solve the problem of fiber raw material agglomeration in local positions.

[0037] Please refer to Figures 3 to 5The deformation 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. The outer ring surface of the bushing 344 is provided with seven circumferentially evenly distributed limiting grooves 347. The heights of the seven limiting grooves 347 increase successively. The fixing block 345 and the seven connecting sliders 346 are evenly 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. The end of the fixing block 345 away from the blade 341 is fixed to the outer side of the bushing 344. The ends of the seven connecting sliders 346 away from the blade 341 are slidably connected with the seven limiting grooves 347 in a one-to-one correspondence. The connecting sliders 346 close to the gap 342 in the three blade assemblies 34 are all fixed to the outer side of the movable rod 32.

[0038] It should be noted that when the deformable stretching member is in use, the movable rod 32 moves downward, which can drive the three connected connecting sliders 346 to slide downward along the corresponding limiting slots 347 first, and the end of the paddle 341 close to the connecting slider 346 is subjected to the downward pulling force of the connecting slider 346, and begins to deform downward, and then drives the other connecting sliders to slide along the corresponding limiting slots 347, while the end of the paddle 341 connected to the fixed block 345 will not move downward due to the fixing effect of the fixed block 345, and the height of each limiting slot 347 is set according to the preset deformation posture of the paddle 341. 46 cooperates with the corresponding limiting slide groove 347 to slide, which can limit and guide the deformation of the paddle 341. When the connecting slider 346 connected to the movable rod 32 slides to the bottom wall of the corresponding limiting slide groove 347, the paddle 341 is deformed to a preset spiral shape, completing the shape switching of the paddle 341. When switching to the first shape again, by controlling the movable rod 32 to move upward, the paddle 341 can gradually restore to a flat shape with the help of its own elasticity. In this way, the deformation stretching member can realize the precise deformation of the paddle 341, so that the paddle 341 can automatically and repeatedly perform stable deformation switching in a preset manner to meet the use requirements of different stirring periods.

[0039] Please refer to Figure 2 The additive delivery mechanism 4 includes a storage container 41, a delivery pump 42 and a delivery pipe 43. The storage container 41 and the delivery pump 42 are fixedly installed on the outside of the mixing barrel 1. The input end of the delivery pump 42 is connected to the bottom of the storage container 41 through a pipe, and the output end of the delivery pump 42 is connected to one end of the delivery pipe 43. The other end of the delivery pipe 43 extends from the outside of the storage container 41 to the inside thereof.

[0040] It should be noted that when the additive delivery mechanism 4 is in use, the additive in the storage container 41 is delivered to the delivery pipe 43 through the delivery pump 42, and then delivered to the bottom of the mixing barrel 1 from the end of the delivery pipe 43 for spraying.

[0041] Please refer to Figure 3 The linear drive component 33 is an electric push rod 336 , which is fixedly mounted on the upper end of the outer side of the stirring shaft body 31 , and its telescopic end is fixed to the top end of the movable rod 32 .

[0042] It should be noted that when the linear telescopic drive assembly is in use, the electric push rod 336 is extended to drive the movable rod 32 to move downward, thereby causing the movable rod 32 to drive the blade 341 to deform.

[0043] Please refer to Figure 1 to Figure 2 The stirring power source 2 includes a mounting frame 21 and a speed regulating motor 22. The mounting frame 21 can be detachably mounted in the middle of the top of the stirring barrel 1. A feeding port is reserved between the two 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 mounted on the top of the mounting frame 21.

[0044] Embodiment 2

[0045] Please refer to Figure 6 to Figure 7 , the difference between the second embodiment of the present invention and the first embodiment is that: the linear drive assembly 33 is a hydraulic drive device, which includes a piston rod 331, a nozzle 332, a sensor switch 333, a first cavity 334 and a second cavity 335. The first cavity 334 and the second cavity 335 are both arranged at the lower end of the stirring shaft body 31, and the upper end of the first cavity 334 is connected 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 slides through the bottom of the stirring shaft body 31 and is fixed to the bottom end of the movable rod 32. The end of the conveying pipe 43 is rotatably connected to the bottom end of the second cavity 335. The nozzle 332 is installed at the bottom end of the stirring shaft body 31, and its interior is connected with the first cavity 334. The sensor switch 333 is installed at the bottom of the second cavity 335. The nozzle 332 is provided with an electronic valve, and the sensor switch 333 is electrically connected to the electronic valve.

[0046] It should be noted that when the above hydraulic drive device is in use, the additive is first delivered to the first cavity 334 through the additive delivery 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, so that the piston rod 331 drives 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 induction switch 333, the induction switch 333 is triggered to start, so that the nozzle 332 is turned on, and the additive delivery mechanism 4 is closed at the same time, and the stirring power source 2 drives the stirring blade mechanism 3 to rotate. During this process, the additive begins to be sprayed outward through the nozzle 332. As the stirring shaft 31 rotates, the additive can be evenly sprayed all around to speed up the mixing speed of the additive and the raw material slurry. As the additive is sprayed, the pressure on the piston rod 331 is reduced. When the pressure is less than the deformation force of the paddle 341, the paddle 341 begins to deform and reset, and drives the movable rod 32 to move upward, and the piston rod 331 moves upward with the movable rod 32, and gradually pushes the additive from the first cavity 334 to the second cavity 335, until the paddle 341 recovers its deformation and the piston rod 331 is reset, and the additive is gradually discharged under the rotation of the stirring shaft. In this way, compared with the electric push rod 336 driving method of the first embodiment, the hydraulic drive device cooperates with the additive delivery mechanism 4 and the stirring shaft 31 to use the introduced additive as a power source to synchronously drive the movable rod 32 to move. On the one hand, the synergistic effect of the introduction of the additive and the deformation of the blade 341 is achieved, and the deformation degree of the blade 341 is synchronously controlled according to the introduction process of the additive, so that the additive and the deformation degree of the blade 341 are synchronously adapted. After the introduction of the additive is completed, the blade 341 also completes the deformation switching synchronously, without the need to set up a separate program control. In addition, a separate drive source is added, which eliminates the need for a separate drive source circuit and control program, and can reduce the power consumption of the stirring blade mechanism 3. On the other hand, it can also make the additive evenly distributed in the stirring barrel 1, thereby accelerating the mixing speed of the additive and the slurry.

[0047] An example of the present specific implementation mode is described above, but the present embodiment is not limited to the above-mentioned specific implementation mode, which is merely illustrative and not restrictive. A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
