Description

Technical Field

[0001] This invention relates to the field of refined cotton production technology, specifically to a dewatering extrusion device for refined cotton production. Background Technology

[0002] Refined cotton is a high-purity cellulose product obtained by refining cotton linters through alkaline cooking, bleaching, and other processes. Its raw material is cotton linters, and its main chemical components are cellulose, lignin, and hemicellulose. The production process of refined cotton includes a dehydration step, which involves separating the moisture from the cooked and bleached wet cotton linters through physical extrusion. The dehydration device is one of the important pieces of equipment in the production of refined cotton. The most common dehydration devices for refined cotton are roller-type dehydration devices.

[0003] According to the extrusion dewatering device for refined cotton production disclosed in the authorization announcement number CN 211650968 U, the dewatering effect is improved and the residual moisture content of the refined cotton pulp after dewatering is reduced, which is beneficial to subsequent conveying and drying. However, after using the above-mentioned existing extrusion dewatering device for refined cotton production, it was found that the existing device only uses the spikes on the rollers to tear and break the refined cotton pulp falling into the crushing chamber to avoid the refined cotton from caking. However, it still cannot restore the refined cotton to its natural fluffy state before absorbing water and before caking. Furthermore, breaking the refined cotton is not conducive to subsequent processing. Summary of the Invention

[0031] 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 of 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.

[0032] Embodiment: Please refer to Figure 1-7The extrusion and dewatering device for refined cotton production shown includes a frame box 1; two left-right distributed squeezing rollers 4 are rotatably connected inside the frame box 1, and a squeezing belt 401 is sleeved on the outer wall of the two squeezing rollers 4; multiple twisting rollers 8 are rotatably connected between the front and rear walls of the frame box 1; a foaming component 2 is provided inside the frame box 1, and the foaming component 2 includes a guiding hopper 201; air-injecting hollow shafts 202 are rotatably connected to the front and rear walls of the guiding hopper 201; and a common air-injecting hollow shaft 202 is connected between the two air-injecting hollow shafts 202. A hollow tube 203 is fixedly connected to the frame box 1. Multiple air injection plates 204 are fixedly connected to the outer wall of the hollow tube 203. These plates are arranged in a circular array. Air distribution grooves 205 are formed inside each plate, communicating with the interior of the hollow tube 203. Multiple exhaust holes 206 are formed on one side of each air distribution groove 205, communicating with the interior of the groove. Arc-shaped cylinders 207 are fixedly connected to both the front and back of the frame box 1. An air guide pipe 208 is fixedly connected to the output end of cylinder 207. The output end of the air guide pipe 208 is fixedly connected to the end of the air-injection hollow shaft 202 via a universal connector. A clearance groove 209 is provided through the inner wall of the arc-shaped cylinder 207. A rocker arm 2010 is slidably connected inside the clearance groove 209. A swing piston 2011 is fixedly connected to the end of the rocker arm 2010. The outer wall of the swing piston 2011 is slidably connected to the inner wall of the arc-shaped cylinder 207. The rocker arm 2010 is fixedly connected to the outer wall of the spring rod 301. On top, multiple kneading rollers 8 are located on the top of the squeezing belt 401. An AC motor 6 is fixedly connected to the side wall of the frame box 1. The output shaft of the AC motor 6 is fixedly connected to the shaft end of one of the squeezing rollers 4. A water collecting chamber block 7 is fixedly connected between the front wall and the rear wall of the frame box 1. A through hole 701 is opened through the top of the water collecting chamber block 7. A drain pipe 702 is fixedly connected to the side wall of the water collecting chamber block 7. The drain pipe 702 communicates with the interior of the water collecting chamber block 7. The drain pipe 702 passes through the side wall of the frame box 1 and extends to its exterior.

[0033] Specifically, the output shaft of the AC motor 6 drives the connected squeezing roller 4 to rotate, and further drives the squeezing belt 401 to rotate in cooperation with another squeezing roller 4. The worker places the refined cotton on top of the squeezing belt 401 through the feeding port 101. The rotating squeezing belt 401 conveys the cotton to the right. During this process, the refined cotton is crushed by multiple twisting rollers 8, which squeeze out the water. The squeezed water flows into the water collection chamber 7 through the drain holes and multiple guide holes 701 on the surface of the squeezing belt 401, and then is discharged to the outside through the drain pipe 702. As the squeezing belt 401 continues to rotate, the dehydrated refined cotton is guided into the guide hopper 201. When the squeezing roller 4 rotates, it drives the drive gear 5 to rotate, which in turn drives the air injection hollow shaft 202 to rotate under the meshing of the external teeth on the cam disc 3015. This, in turn, drives the hollow tube 203 and multiple air injection points. The plate 204 rotates together to receive the refined cotton conveyed by the dewatering belt 401. When the cam disc 3015 rotates, it drives the cam groove 30015 to rotate together. Furthermore, under the sliding connection between the cam groove 30015 and the sliding pin 3014, it drives the rack 3013 to move up and down along the linear guide rail 3012, thereby causing the incomplete gear 3011 meshing with the rack 3013 to rotate back and forth. This causes the spring bar 301 connected to the incomplete gear 3011 to rotate synchronously, further driving the swing arm 2010 to flip together. The air entering the arc-shaped cylinder 207 from the air inlet 2012 is compressed into the air injection hollow shaft 202 through the air guide pipe 208, and then enters the interior of multiple air distribution grooves 205 through the hollow pipe 203. Finally, it is blown out through multiple exhaust holes 206 to blow and foam the refined cotton received on the air injection plate 204, making it more loose.

[0034] In this embodiment, reference is made to Figure 2 , Figure 3 , Figure 4 , Figure 8 , Figure 9As shown, the frame box 1 is equipped with a spring tension assembly 3 inside. The spring tension assembly 3 includes two spring tension rods 301 distributed front and rear, located at the front and rear of the frame box 1. Multiple left-right distributed spring tension rocker arms 302 are fixedly connected to the outer walls of both spring tension rods 301. The bottom of the two spring tension rocker arms 302 at the front and rear positions is fixedly connected to a tensioning wire 303, which movably penetrates the interior of the frame box 1. Two left-right distributed first adapter seats 306 are rotatably sleeved on the outer walls of both spring tension rods 301. The first adapter seats 306 are connected to the front and rear sides of the frame box 1. The spring tension assembly 3 also includes two front-to-back striking rods 304 located inside the frame box 1. Multiple left-to-right patting rods 305 are fixedly connected to the outer walls of each striking rod 304, positioned above multiple tensioning wires 303. Two left-to-right second adapter seats 307 are rotatably sleeved on the outer walls of each striking rod 304, and are fixedly connected to the front and rear walls of the frame box 1 respectively. One end of each of the two spring tension rods 301 is fixedly connected to a drive pulley 3010. One end of each pulley is fixedly connected to a driven pulley 308. The driving pulley 3010 is connected to the corresponding driven pulley 308 via a power belt 309. Incomplete gears 3011 are fixedly connected to the outer walls of both spring rods 301. Linear guide rails 3012 are fixedly connected to the front and rear surfaces of the frame box 1. Racks 3013 are slidably connected to the outer surfaces of both linear guide rails 3012. The two racks 3013 are located between the two incomplete gears 3011, and each rack 3013 meshes with one of the two incomplete gears 3011. The two racks 3013 are located on the side where they are close to each other. Each part is fixedly connected with a sliding pin 3014. A cam disk 3015 is fixedly connected to the outer wall of each of the two air-injection hollow shafts 202. A cam groove 30015 is opened on the side of each of the two cam disks 3015 that are far apart. The two cam grooves 30015 are slidably connected to the two sliding pins 3014 respectively. An external tooth is opened on the outer wall of one of the cam disks 3015. A drive gear 5 is fixedly connected to the shaft end of one of the water-squeezing rollers 4. The drive gear 5 meshes with the external tooth of one of the cam disks 3015. The cotton-stretching steel wire 303 is made of flexible steel filaments. The cotton-patting stick 305 is made of elastic plastic material.

[0035] Specifically, when the two elastic rods 301 rotate in opposite directions, they drive the multiple elastic rocker arms 302 connected to them to swing, thereby continuously tightening the multiple cotton-stretching wires 303. When the cotton-stretching wires 303 are repeatedly tightened, they generate amplitude, which in turn elasticates the cotton conveyed at the top of the conveyor belt 901, thereby quickly loosening the dehydrated refined cotton and making it fluffy. When the two elastic rods 301 rotate in opposite directions, they drive the two drive pulleys 3010 to rotate synchronously, which in turn drive the two driven pulleys 308 to rotate synchronously under the connection of the two power belts 309. This causes the two beaters 304 connected to the two driven pulleys 308 to flip in opposite directions, and drive the multiple cotton-beating sticks 305 to swing up and down to beat the refined cotton, thereby further improving the fluffy effect of the refined cotton.

[0036] In this embodiment, reference is made to Figure 7 As shown, an air inlet 2012 is provided through the outer wall of the arc-shaped cylinder 207, and a first telescopic air stop curtain 2013 and a second telescopic air stop curtain 2014 are fixed inside the arc-shaped cylinder 207.

[0037] Specifically, by setting the first telescopic air stop curtain 2013 and the second telescopic air stop curtain 2014, the clearance groove 209 is sealed, so that when the swing piston 2011 compresses air, the air inside the arc-shaped cylinder 207 will not leak out from the clearance groove 209 to the outside.

[0038] In this embodiment, reference is made to Figure 3 , Figure 4 As shown, two left-right distributed conveyor rollers 9 are rotatably connected between the front and rear walls of the frame box 1. A conveyor belt 901 is sleeved around the periphery of the two conveyor rollers 9. The conveyor belt 901 is located at the bottom of multiple cotton-stretching steel wires 303. A passive synchronous wheel 10 is fixedly connected to the rear end of one of the conveyor rollers 9. A synchronous belt 11 is sleeved on the outer wall of the passive synchronous wheel 10. A driven synchronous wheel 12 is connected to the end of the synchronous belt 11 away from the passive synchronous wheel 10. The driven synchronous wheel 12 is fixedly connected to the shaft end of one of the squeezing rollers 4.

[0039] Specifically, since the end of the squeezing roller 4 and the end of the conveying roller 9 are linked by the passive synchronous wheel 10, the synchronous belt 11 and the driven synchronous wheel 12, the squeezing roller 4 will drive the conveying roller 9 to rotate when it rotates, which will further cause the conveyor belt 901 to run and convey the dehydrated refined cotton to the left.

[0040] In this embodiment, reference is made to Figure 1As shown, a feeding port 101 is provided on the top of the frame box 1, and the feeding port 101 extends into the interior of the frame box 1. The feeding port 101 is located on the top of the dewatering belt 401. An unloading port 102 is provided on the left side of the frame box 1, and the unloading port 102 extends into the interior of the frame box 1. The unloading port 102 is located at one end of the conveyor belt 901.

[0041] Specifically, by opening the inlet 101, un-dehydrated refined cotton is fed onto the top of the dewatering belt 401, and by setting the drain pipe 702, the conveyor belt 901 is unloaded.

[0042] In this invention, a squeezing and dewatering device for refined cotton production operates by having the output shaft of an AC motor 6 drive the connected squeezing roller 4 to rotate. In conjunction with another squeezing roller 4, the squeezing belt 401 is driven to rotate. The worker places the refined cotton on top of the squeezing belt 401 through the inlet 101. The rotating squeezing belt 401 then transports the cotton to the right. During this process, the refined cotton is crushed by multiple twisting rollers 8, which squeeze out the water. The squeezed water flows into the water collection chamber 7 through the drain holes and multiple guide holes 701 on the surface of the squeezing belt 401, and is then discharged to the outside through the drain pipe 702.

[0043] As the dewatering belt 401 continues to operate, the dewatered refined cotton is guided into the guide hopper 201. The dewatering roller 4, while rotating, also drives the drive gear 5 to rotate, further engaging with the external teeth on the cam disc 3015 to rotate the air-injection hollow shaft 202. This, in turn, drives the hollow tube 203 and multiple air-injection plates 204 to rotate together, receiving the refined cotton conveyed by the dewatering belt 401. The rotation of the cam disc 3015 also drives the cam groove 30015 to rotate. Furthermore, with the cam groove 30015 slidingly connected to the sliding pin 3014, the rack 3013 moves up and down along the linear guide rail 3012, thus causing the rack 3013 to reciprocate. The 13-phase meshing incomplete gear 3011 rotates back and forth, causing the spring bar 301 connected to the incomplete gear 3011 to rotate synchronously, further driving the swing arm 2010 to rotate together. The air entering the arc-shaped cylinder 207 from the air inlet 2012 is compressed into the air-injection hollow shaft 202 through the air guide pipe 208, and then distributed to the interior of multiple air distribution grooves 205 through the hollow pipe 203. Finally, it is blown out through multiple exhaust holes 206 to blow and foam the refined cotton on the air injection plate 204, making it more loose. As the multiple air injection plates 204 rotate, the refined cotton is guided to the top of the conveyor belt 901.

[0044] Because the end of the squeezing roller 4 and the end of the conveyor roller 9 are linked through the passive synchronous pulley 10, the synchronous belt 11, and the driven synchronous pulley 12, the squeezing roller 4 rotates, causing the conveyor roller 9 to rotate, which in turn causes the conveyor belt 901 to run, conveying the dehydrated refined cotton to the left. When the two elastic rods 301 rotate in both directions, they drive the multiple elastic rocker arms 302 connected to them to swing, thereby continuously tightening the multiple cotton-stretching steel wires 303. The repeated tightening of the cotton-stretching steel wires 303 generates amplitude, which affects the conveyor belt 901. 1. The cotton conveyed at the top is fluffed, which quickly loosens the dehydrated refined cotton and makes it fluffy. When the two fluffing rods 301 rotate in opposite directions, they drive the two drive pulleys 3010 to rotate synchronously. Furthermore, under the connection of the two power belts 309, they drive the two driven pulleys 308 to rotate synchronously. This causes the two beating rods 304 connected to the two driven pulleys 308 to flip in opposite directions and drive multiple cotton-beating rods 305 to swing up and down to beat the refined cotton, thereby further improving the fluffy effect of the refined cotton.

[0045] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
