Description

Technical Field

[0001] This invention relates to the field of chemical machinery and equipment, and more specifically, to a uniform material distribution structure for a belt-type aging box. Background Technology

[0002] Alkali cellulose aging is a core process in viscose fiber preparation, directly determining the uniformity of polymerization and physical properties of the finished fiber. Belt aging boxes have become the mainstream equipment for current aging processes due to their strong continuous production capacity and stable temperature control.

[0003] In actual production, after the material is initially dispersed by the top spiral distributor, it falls onto the upper conveyor belt. During the cross-belt transfer between the upper and lower conveyor belts, the material falls concentratedly along the middle of the width, resulting in a distribution deviation with accumulation in the middle and lack of material on both sides. At the same time, alkali cellulose is a flocculent and highly viscous material, which easily adheres and clumps together during the fall, and may even bridge and block at the guide structure. After the clumps fall onto the lower conveyor belt, they will cause local compaction of the material layer and significant differences in air permeability. Ultimately, this leads to inconsistent aging reaction rates in different areas of the box, resulting in poor uniformity of finished product quality. Existing material improvement solutions for belt aging boxes still have multiple technical shortcomings: First, conventional flow guiding structures mostly use straight plates with equal gaps, which cannot adapt to the material distribution characteristics of more material in the middle and less on the sides. They can only achieve simple diversion and cannot correct the thickness deviation of the fabric in the width direction from the root. Second, the flow guiding plates do not have a self-cleaning function. After the continuous adhesion and accumulation of flocculent material, the flow gap will gradually narrow, eventually leading to diversion failure. The problem of uneven fabric distribution will recur, requiring frequent machine stops to open the cover for manual cleaning, which seriously restricts the efficiency of continuous production. In order to solve the above problems, a uniform fabric distribution structure of belt-type aging box is proposed. Summary of the Invention

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a uniform fabric distribution structure for belt-type aging boxes, which has the following beneficial effects: This invention can divert and guide the transported material through the built-in equalization component in the shell, which can specifically solve the problem of material accumulation in the middle and lack of material on both sides, and achieve uniform lateral distribution of material. This ensures the basic uniformity of subsequent aging operations from the source. It can also use the leveling component to level and loosen the material, regulate the thickness of the material layer, and improve the fluffiness of the material, which is very beneficial to the stable progress of subsequent aging processes. The material can also be dispersed in real time by the reciprocating motion of the leveling component linked to the small mechanical vibration of the dispersing component. This breaks up agglomerates and clumps generated during material conveying, preventing local compaction and poor air permeability caused by agglomerated materials. Furthermore, the small motion of the dispersing component can be linked to the intermittent misalignment component, causing the guide plate to move intermittently and slightly up and down. This clears the material stuck in the gap between the guide plates in real time, effectively preventing blockage of the flow guiding structure and ensuring the continuous and stable flow guiding and dispersing performance of the distribution component. This effectively achieves a uniform material layer, moderate looseness, and stable material distribution, significantly improving the uniformity of aging processing and the consistency of finished product quality.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0033] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0034] For examples, please refer to Figures 1-15 A uniform material distribution structure for a belt conveyor aging box includes a material distribution mechanism 100, which includes a first chain conveyor belt 104 and a second chain conveyor belt 105 disposed inside the aging box body 101. A housing 107 is disposed between the first chain conveyor belt 104 and the second chain conveyor belt 105. The inner cavity of the housing 107 is provided with a distribution component for guiding and pre-distributing the material, and a leveling component disposed on one side of the housing 107 for leveling and fixing the thickness of the distributed material. A material distribution auxiliary mechanism 200 is disposed below the inner cavity of the housing 107. The material distribution auxiliary mechanism 200 includes a dispersing component disposed below the inner cavity of the housing 107 for breaking up the agglomerates of the distributed material, and an intermittent misalignment component disposed on one side of the dispersing component for preventing the distribution component from clogging.

[0035] During operation, material falls onto the surface of the first chain conveyor belt 104 via the spiral distributor 103 at the top of the aging box. The first chain conveyor belt 104 carries the material to the second chain conveyor belt 105, which runs in the opposite direction. During this cross-belt material feeding process, the material falls concentratedly along a narrow line. Combined with the tendency of alkali cellulose flocculent adhering material to agglomerate and bridge, and the horizontal inertia of the falling material, this easily forms a material layer that is piled up in the middle and sparse on both sides, with a thickness deviation along the conveying direction. The material falls into the internal area of ​​the shell 107 between the first chain conveyor belt 104 and the second chain conveyor belt 105. First, the material is diverted and guided by the equalization component within the shell 107. The material exhibits a distribution defect where it is thicker in the middle and thinner on both sides in the width direction. Subsequently, the material falls below the housing 107, where the dispersing component of the fabric auxiliary mechanism 200 vibrates and disperses the agglomerated and bridged material. The dispersed material continues to move with the second chain conveyor belt 105 and is eventually conveyed to the leveling component to complete the thickness leveling and combing operations. At the same time, the reciprocating motion of the leveling component can be linked to the continuous small-amplitude vibration of the dispersing component. During the operation of the dispersing component, it further links the intermittent misalignment component to work, causing the guide plate 111 of the equalization component to produce intermittent misalignment movement, achieving a self-cleaning and anti-clogging effect, thereby improving the thickness deviation of the material layer in both the width and conveying directions, and thus ensuring the aging effect of the material.

[0036] In the example of this application, the equalizing component includes a plurality of guide plates 111 disposed in the inner cavity of the housing 107. The two ends of the plurality of guide plates 111 are respectively attached to the inner wall of the housing 107. The plurality of guide plates 111 are arranged sequentially along the material feeding to discharging direction. A guide gap is formed between the plurality of guide plates 111 to allow the material to pass through. The guide gap between the guide plates 111 in the middle region is smaller than the guide gap between the guide plates 111 in the two side regions. The tops of all the guide plates 111 together form an arc-shaped guide surface. The top of the guide plate 111 is set as a smooth arc surface.

[0037] As a preferred example of the present invention, the material falls from the end of the first chain conveyor belt 104 into the interior of the housing 107. The material falls in a form that is concentrated in the middle and less on the sides, and falls directly into the guide gap between multiple sets of guide plates 111 arranged along the material flow direction. By setting the guide gap in the middle area to be smaller than the guide gap in the side areas, it adapts to the material characteristics of the cross-belt material falling with concentrated material in the middle and less on the sides, and guides and distributes the excess material in the middle to the sides, thereby improving the defect of the wide-width distribution caused by the cross-belt material falling from the source. The tops of multiple sets of guide plates 111 together form an arc-shaped guide surface, and the top is a smooth arc surface. Alkali cellulose is an adhesive flocculent material, and the arc-shaped smooth surface can reduce the adhesion of the material to the wall and avoid the material bridging and accumulating at the plate position. At the same time, it buffers and guides the falling material, weakens the horizontal inertia of the falling material, alleviates the problem of uneven thickness in the front and back of the conveying direction, and reduces the splashing and deflection of the material. Multiple guide plates 111 are attached to the inner wall of the shell 107 at both ends to guide the material in layers and areas, so that the material is evenly distributed laterally, providing a regular and uniform material base for subsequent dispersing and leveling processes.

[0038] It is worth noting that the outer surface of the guide plate 111 is also set as a smooth surface, thereby reducing the adhesion of materials.

[0039] In the example of this application, fixing frames 108 are fixedly installed on both the front and rear sides of the first chain conveyor belt 104 and the second chain conveyor belt 105. The fixing frames 108 are detachably connected to the inner wall of the aging box body 101. The middle of both sides of the housing 107 is fixedly connected to the fixing frames 108. A spiral distributor 103 is provided at the upper feed port of the aging box body 101. The first chain conveyor belt 104 is located below the discharge end of the spiral distributor 103. A discharge port 106 is provided at the lower part of the aging box body 101. The discharge port 106 is located below the second chain conveyor belt 105.

[0040] As a preferred example of the present invention, when the equipment is running, the material is first divided by the spiral distributor 103 at the top of the aging box to break up large clumps and pre-distribute the initial feed, reducing the working load of the rear feeding mechanism 100. The material after the initial diversion falls stably into the first chain plate conveyor belt 104. The first chain plate conveyor belt 104 and the second chain plate conveyor belt 105 run in opposite directions. The two are positioned and installed by the fixing frames 108 on the front and rear sides. The fixing frames 108 are detachably connected to the aging box body 101. The shell 107 is fixed between the fixing frames 108 on both sides, so that the internal feeding components are stably suspended on the material falling path between the two conveyor belts, receiving the material falling from the first chain plate conveyor belt 104. After the feeding and leveling are completed, the material is finally stably discharged from the discharge port 106 below the second chain plate conveyor belt 105. The entire material conveying path is regular and there are no dead corners.

[0041] It is worth noting that a discharge channel will be provided below the discharge port 106 to facilitate the conveying of aged materials, and the closed discharge channel can ensure a sealed aging environment inside the aging box.

[0042] In the example of this application, the leveling assembly includes a rack slide 116 slidably disposed above the fixed frame 108. A rotating rod 113 is disposed through the interior of the rack slide 116. The rotating rod 113 is rotatably connected to the outer wall of the housing 107 via a bearing. A second sprocket 114 is fixedly mounted on the other end of the rotating rod 113. Drive motors 109 are fixedly mounted on both the front and rear sides of the aging box body 101. Both drive motors 109 are servo motors. The two servo motors are connected by a pre-load mechanism. The PLC controller with a motor synchronization control algorithm can be used for synchronous control, or the existing motor synchronization controller can be used directly. The drive end of the drive motor 109 is fixedly installed with a first sprocket 110. The middle part of the rotating rod 113 is fixedly installed with an incomplete gear 115. The rack slide 116 is fixedly installed with a trapezoidal scraper 117 on the side near the discharge port 106. The lower end of the trapezoidal scraper 117 is fixedly installed with multiple comb teeth 118, and the multiple comb teeth 118 are evenly distributed among each other.

[0043] As a preferred example of the present invention, when the equipment is working, the drive motor 109 drives the first sprocket 110 to rotate, and drives the second sprocket 114 to rotate synchronously with the rotating rod 113 through the transmission chain 112. The rotating rod 113 drives the incomplete gear 115 in the middle to rotate continuously. By utilizing the meshing relationship between the incomplete gear 115 and the rack slide 116, the rotational motion is converted into the horizontal linear reciprocating motion of the rack slide 116, which in turn drives the trapezoidal scraper frame 117 fixed at the end of the rack slide 116 to slide back and forth along the width of the fabric. When the material after being dispersed and vibrated is transported to the bottom of the scraper assembly, the reciprocating trapezoidal scraper frame 117 completes the overall thickness fixation of the material. At the same time, the comb teeth 118 evenly distributed at its lower end can finely comb and loosen the surface layer of the alkali cellulose flocculent material, so that the overall thickness of the material layer is consistent and the material is loose and uniform, which is conducive to the subsequent hot air penetration, reduces the difference in aging reaction rate in different areas, and improves the aging uniformity.

[0044] In the example of this application, the first sprocket 110 and the second sprocket 114 are connected by a transmission chain 112. The incomplete gear 115 meshes with the inner cavity of the rack slide 116. A first slider 119 is fixedly installed at the lower middle part of the rack slide 116. A first groove 120 is provided above the fixed frame 108. The size of the first slider 119 is adapted to the size of the first groove 120, and the first slider 119 is slidably connected to the first groove 120.

[0045] As a preferred example of the present invention, the first slider 119 at the lower end of the rack slide 116 engages inside the first slide groove 120 above the fixed frame 108, thereby limiting and guiding the reciprocating motion of the rack slide 116, constraining the slide's running trajectory, effectively preventing deviation, shaking, and jamming during operation, and ensuring stable meshing and smooth transmission between the incomplete gear 115 and the rack slide 116.

[0046] In the example of this application, the disintegration component includes a plurality of fixing rods 201 disposed below the inner cavity of the housing 107. At least three sets of fixing rods 201 are provided. A plurality of elastic plates 206 are fixedly installed at the lower end of the fixing rods 201. Hollow balls 207 are connected to the ends of the elastic plates 206. A square limiting rod 203 is welded to the upper end of the fixing rods 201. Limiting frames 205 are welded to both sides of the housing 107. The square limiting rod 203 moves through the interior of the limiting frame 205. A first spring 204 is sleeved on the outer side of the lower end of the square limiting rod 203. A plurality of arc-shaped grooves 211 are opened at the upper end of the rack slide 116. A semi-circular protrusion 202 is fixedly installed on the side of the upper end of the fixing rod 201 near the arc-shaped grooves 211.

[0047] As a preferred example of the present invention, when the rack slide 116 reciprocates linearly with the incomplete gear 115, the multiple sets of arc-shaped grooves 211 opened on it move synchronously. During the movement, they will intermittently contact, engage, and disengage with the semi-circular protrusion 202 at the upper end of the fixed rod 201. With the vertical limiting effect of the limiting frame 205 and the square limiting rod 203, the fixed rod 201 is driven to produce regular small up and down movement. The elastic sheet 206 and hollow ball 207 at the lower end of the fixed rod 201 vibrate synchronously with the fixed rod 201 at high frequency and small amplitude. This provides a comprehensive and flexible vibration and dispersion treatment for the alkali cellulose material that has not yet been leveled after being diverted by the guide plate 111. This breaks up the agglomeration and bridging phenomena formed during the material falling process, and avoids the problems of local compaction, uneven material layer, and poor air permeability caused by the agglomerated flocs entering the leveling process. Furthermore, the vibration and dispersion method of the flexible elastic sheet 206 and hollow ball 207 will not damage the original structure of the alkali cellulose flocs. While breaking up agglomerates, it ensures the integrity of the material properties. The loose material after vibration then enters the leveling process, further improving the uniformity of the fabric.

[0048] It is worth noting that both the elastic sheet 206 and the hollow ball 207 are mounted on the second chain conveyor belt 105, thereby ensuring the conveying of the dispersed materials.

[0049] In the example of this application, the upper end of the first spring 204 is fixedly connected to the lower end of the limiting frame 205, the lower end of the first spring 204 is fixedly connected to the upper end of the fixing rod 201, the plurality of arc grooves 211 are equidistantly distributed, and the size of the semi-circular protrusion 202 is adapted to the size of the arc groove 211.

[0050] As a preferred example of the present invention, the first spring 204 sleeved on the upper end of the fixed rod 201 is fixed at both ends to the limiting frame 205 and the fixed rod 201 respectively, forming a stable elastic reset structure. When the arc groove 211 of the rack slide 116 moves forward, the fixed rod 201 is pushed upward, and the first spring 204 is compressed and stored. When the semi-circular protrusion 202 is inserted into the arc groove 211, the first spring 204 releases its elastic force and drives the fixed rod 201 to fall back and reset quickly, thereby forming a continuous and stable small-amplitude up-and-down vibration action. At the same time, the arc grooves 211 evenly distributed on the rack slide 116 can ensure that the vibration frequency, stroke and rhythm of each set of fixed rods 201 are completely uniform, so that the material in the entire fabric area inside the shell 107 can be subjected to uniform and consistent vibration and dispersion, and there will be no situation of incomplete dispersal of local clumps or excessive vibration in some areas. It continuously and stably breaks the bridging defects of alkali cellulose material agglomeration and ensures uniform material looseness.

[0051] In the example of this application, the intermittent misalignment component includes a connecting rod 209 mounted on a fixed rod 201 on the side away from the trapezoidal leveling frame 117. A fixing strip 208 is fixedly mounted on the outer side of the connecting rod 209. The fixing strip 208 is provided with a plurality of protrusions 210. A strip groove 212 is formed on the inner wall of the housing 107 on the side away from the trapezoidal leveling frame 117. A round rod 213 is provided through the inner cavity of the strip groove 212. A second sliding groove 214 is formed on the inner cavity of the strip groove 212 near the guide plate 111. A second slider 215 is fixedly mounted on the upper end of the round rod 213. The second slider 215 is fixedly connected to the corresponding guide plate 111. The lower end of the round rod 213 is in contact with the upper end of the protrusions 210.

[0052] As a preferred example of the present invention, during the operation of the dispersing component, the fixing rod 201 continuously vibrates up and down slightly, causing the connecting rod 209 connected to the side to move up and down synchronously with the fixing strip 208. The protrusions 210 spaced apart on the fixing strip 208 rise and fall synchronously with the fixing strip 208, intermittently pushing the round rod 213 in the strip groove 212 upward. The round rod 213 drives the corresponding guide plate 111 to produce a slight displacement through the second slider 215 at the upper end, thereby causing the corresponding guide plate 111 to produce a momentary misalignment effect, thereby disturbing and peeling off the alkali cellulose flocs that are adhered, bridged and stuck in the guide gap, realizing the intermittent self-cleaning effect of the even distribution component, effectively avoiding the gap of the guide plate 111 being blocked and bridged by flocs, and preventing the fabric defect of being thick in the middle and thin on both sides from recurring due to the failure of the diversion.

[0053] In the example of this application, the size of the second slider 215 is adapted to the size of the second slide groove 214, and the second slider 215 is slidably connected to the second slide groove 214. The upper end of the inner cavity of the strip groove 212 is fixedly installed with a second spring 216, and the other end of the second spring 216 is fixedly connected to the upper end of the round rod 213. The protrusions 210 correspond one-to-one with some of the guide plates 111. The protrusions 210 are arranged at intervals, and each protrusion 210 is respectively located below the corresponding guide plate 111.

[0054] As a preferred example of the present invention, the second slider 215 at the upper end of the round rod 213 is slidably assembled inside the second groove 214, which can limit the displacement trajectory of the guide plate 111, allowing only a small displacement of the guide plate 111. At the same time, the second spring 216 at the upper end of the strip groove 212 always applies a downward pushing force to the round rod 213. When the protrusion 210 moves down with the fixing bar 208 and loses the pushing force on the round rod 213, the second spring 216 quickly drives the round rod 213, the second slider 215 and the guide plate 111 to reset, so that the guide plate 111 immediately returns to the initial design working position. Only a brief misalignment and unblocking is completed at the moment the protrusion is raised. At other times, the guide plate 111 maintains the standard flow guiding gap, which not only realizes the anti-blocking and self-cleaning function, but also fully ensures the accuracy of normal and even distribution of material, taking into account both the anti-blocking effect and the stability of the fabric, and is suitable for the working conditions where alkali cellulose is prone to adhesion and bridging.

[0055] Specific working principle: After being pre-dispersed by the spiral distributor 103, the material falls onto the first chain conveyor belt 104. It is then conveyed to the end of the belt and falls into the housing 107. First, it enters the guide plates 111 arranged in a gradient gap along the arc-shaped guide surface, diverting excess material to both sides, thus completing the pre-division in the width direction. The diverted material continues to fall through the dispersing station, where the elastic plates 206 and hollow balls 207, which vibrate in conjunction with the rack and pinion slide 116, gently strike the falling material, breaking up any knots. The bridging phenomenon occurs when the dispersed material falls evenly onto the second chain conveyor belt 105 and is conveyed forward to the leveling station. The trapezoidal leveling frame 117 and comb teeth 118, which reciprocate along the width of the belt, comb the material layer to a fixed thickness, forming a uniform and fluffy material layer. During the above process, the vertical vibration of the fixed rod 201 synchronously drives the fixed strip 208 to rise and fall, intermittently pushing the corresponding guide plate 111 to produce vertical misalignment, peeling off the lint adhering to the gap, and realizing real-time self-cleaning of the guide gap.

[0056] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
