Description

TECHNICAL FIELD

[0001] The application belongs to the field of cotton product processing equipment, and particularly relates to a softening and noise-reducing atomization treatment equipment for cotton-containing sheet. BACKGROUND

[0002] Traditional cotton quilts adopt raw cotton fibers, and contain a large amount of protein, sugar, cotton ester and cotton wax. During storage, due to reasons such as microorganisms, temperature and humidity environment, etc., peculiar smell is easily generated. The cotton quilt can remove the sugar, protein, ester impurities in the cotton fiber through chemical or physical methods, but such process easily leads to roughening of the fiber surface, reduction of softness, rough and dry cotton fiber, increase of friction coefficient, and thus large friction force between fibers and large noise, which affects the use experience of customers on the product made of the cotton-containing sheet.

[0003] In the prior art, the existing method is to atomize the softening treatment liquid and then soak the cotton-containing sheet to reduce the friction coefficient between the cotton fibers, so as to achieve the effect of softening and noise reduction. However, the existing softening treatment device has the following problems: 1. In the existing softening treatment process, about 70% of the atomized softening agent is not fully utilized and is directly discharged, causing waste of the softening agent.

[0004] 2. In the existing softening treatment process, the soaking effect of the softening agent is poor, and the softening agent is not uniformly distributed in the cotton-containing sheet, which affects the final quality.

[0005] 3. In the existing softening treatment process, it is difficult to treat the flying cotton, which easily leads to flying of the flying cotton everywhere and affects the softening treatment effect. SUMMARY

[0006] The present application overcomes the deficiencies of the prior art and solves the technical problem of spraying atomized softening treatment liquid on the lint-containing fluff on the cylinder during the operation of the carding machine, thereby avoiding the rough and harsh cotton fibers after defatting treatment, which causes large friction between the fibers and generates a lot of noise. By spraying softening treatment liquid in the lint-containing fluff during the carding process, the cotton fibers are smoother during carding, and the lint fibers can be more smoothly arranged in a uniform direction. Moreover, after the lint-containing fluff is sprayed with the softening agent and subjected to the carding action of the cylinder and the cover plate, the softening agent is more evenly distributed in the lint-containing fluff. The lint-containing fluff treated with the softening agent has reduced friction between the lint fibers and is less likely to break. Compared to the traditional simple three-stroke roller carding machine, the device can effectively reduce the lint generated by the friction and breakage of the lint fibers, thereby improving the utilization rate of cotton raw materials, reducing waste, and avoiding the problem of deteriorating processing environment caused by lint. The use of the grid plate allows the atomized softening agent sucked into the suction chamber to re-agglomerate and condense into a liquid, which is then returned to the atomizer to mix with the softening treatment liquid in the atomizer for reuse. This ensures the softening treatment effect of the lint-containing fluff, improves the utilization rate of the softening agent, and ensures the uniformity of the softening treatment of the lint-containing fluff. By setting the filter screen layer, the lint sucked into the cylinder can be filtered. The filter screen layer can rotate with the cylinder, so that the filter screen layer between the first guide roller and the second guide roller is constantly replaced and updated. Compared to the fixed small-area filter screen, the service life is longer and the maintenance and replacement frequency is lower. The device is improved based on the traditional three-stroke roller carding machine. The device is compatible with the traditional three-stroke roller carding machine in some structures, so that the traditional carding machine parts can be used for maintenance and replacement of damaged parts, thereby saving maintenance costs.

DETAILED DESCRIPTION

[0032] In order to make the person skilled in the art better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application.

[0033] As Figures 1-8As shown, a softening and noise reduction cotton flocking atomization treatment device includes a carding machine support 10, two opposite cylinder supports 11 are fixedly connected on the carding machine support 10, two opposite end covers 12 are fixedly connected on the two sides of the two cylinder supports 11 close to each other, a hollow cylinder drum 13 is rotatably connected between the two end covers 12, a cylinder group 41 and a three-stick roller group 42 are arranged on the carding machine support 10 at the two sides of the cylinder drum 13, two atomization sprayers 26 are fixedly connected between the two cylinder supports 11 at the two sides of the top of the cylinder drum 13, each atomization sprayer 26 points to the surface of the cylinder drum 13, an atomizer 28 is arranged on one side of the carding machine support 10, the discharge end of the atomizer 28 is communicated and connected with the two atomization sprayers 26 through an atomization conduit 27, and a softening treatment liquid is stored in the liquid storage cavity of the atomizer 28. In this embodiment, the softening treatment liquid preferably contains siloxane and polyether modified silicone oil (6:3), and the pH value is in the range of 7.0-7.5.

[0034] The device is a three-stick roller carding machine, which improves the structure of the cylinder on the basis of the traditional three-stick roller carding machine and adds an atomization sprayer 26 and an atomizer 28, so that the softening treatment liquid is sprayed on the cotton flocking on the cylinder during the working process of the carding machine, thereby avoiding the rough and harsh cotton fibers after defatting treatment, which causes large friction between the fibers and generates a large noise, affecting the customer's use experience of the product made of cotton flocking.

[0035] Moreover, by spraying the softening treatment liquid in the cotton flocking during the carding process, the cotton fibers are smoother during carding, the cotton fibers can be more smoothly arranged in a unified direction, and the softening agent can be more uniformly distributed in the cotton flocking after the cotton flocking sprayed with the softening agent is carded by the cylinder and the cover plate. Moreover, the cotton flocking treated by the softening agent has reduced friction between the cotton fibers and is not easy to break, thereby the device can effectively reduce the flying flock caused by the friction and breakage of the cotton fibers compared with the traditional three-stick roller carding machine, thereby improving the utilization rate of the cotton raw material, reducing waste, and avoiding the problem of deterioration of the processing environment caused by the flying flock.

[0036] Meanwhile, the device is improved on the basis of the traditional three-stick roller carding machine, and is universal in part of the structure with the traditional three-stick roller carding machine, that is, the components of the traditional carding machine can be used when subsequent maintenance and replacement of damaged components are performed, thereby saving maintenance costs.

[0037] For example, Figures 1-8As shown, the surface of the cylinder 13 is evenly distributed with a plurality of groups of through holes, and the inner part of the cylinder 13 between the two end covers 12 is fixedly connected with an air suction cavity box 20. The top of the air suction cavity box 20 is provided with two openings corresponding to the two atomizing sprayers 26 respectively, and the air suction cavity box 20 is provided with an air suction port 22 at one end. The end of the air suction cavity box 20 close to the arc-shaped part at the bottom of the air suction cavity box 20 is provided with a through liquid discharge port 23. The air suction port 22 and the liquid discharge port 23 pass through the corresponding one of the end covers 12. The air suction cavity box 20 is fixedly connected with a group of grating plates 21 in each of the two openings. Each group of grating plates 21 is arranged in close intervals, and the two groups of grating plates 21 converge towards the center of the air suction cavity box 20 and leave a cavity in the center of the air suction cavity box 20. The cavity is in communication with the air suction port 22 and the liquid discharge port 23. The liquid discharge port 23 is connected with a liquid guide pipe 32 at one end of the end cover 12. The liquid guide pipe 32 is connected with a liquid pump 31 at the end away from the liquid discharge port 23. The liquid storage cavity of the atomizer 28 stores a softening treatment liquid. The liquid pump 31 is in communication with the liquid storage cavity of the atomizer 28. The air suction port 22 is connected with an air guide pipe 30 at one end of the end cover 12. The air guide pipe 30 is connected with a high-pressure fan 29 at the end away from the air suction port 22.

[0038] By setting the high-pressure fan 29 to generate airflow, a negative pressure is continuously generated in the air suction cavity box 20. Therefore, during the process of spraying the atomized softening agent on the cotton flock-containing sheet, the atomized softening agent that is not fully utilized is sucked into the air suction cavity box 20. The arrangement of the grating plates 21 can effectively increase the contact area with the atomized softening agent. Therefore, the atomized softening agent gradually gathers and condenses into liquid during the process of passing through the densely arranged grating plates 21, and finally slides to the liquid discharge port 23 and is returned to the atomizer 28 through the liquid guide pipe 32 and the liquid pump 31 for reuse, thereby avoiding the waste of the softening agent.

[0039] Moreover, the negative pressure recovery of the softening agent can make the softening agent sprayed by the atomizing sprayer 26 more fully infiltrate the cotton flock-containing sheet, thereby improving the softening treatment efficiency and effect on the cotton flock-containing sheet.

[0040] Moreover, after the softening agent that is not fully utilized infiltrates the cotton flock-containing sheet, its concentration changes. If it is directly used, the softening treatment effect on the cotton flock-containing sheet is limited. The use of the grating plates 21 can make the atomized softening agent sucked into the air suction cavity box 20 re-gather and condense into liquid, and then return to the atomizer 28 to mix with the softening treatment liquid in the atomizer 28 for reuse. Therefore, the softening treatment effect on the cotton flock-containing sheet can be ensured, the utilization rate of the softening agent is improved, and the uniformity of the softening treatment on the cotton flock-containing sheet is ensured.

[0041] As shown in the drawings, Figures 1-8As shown, the filter screen layer 17 is arranged around the outside of the suction cavity box 20 in the cylinder 13, and the filter screen layer 17 in this embodiment is preferably a flexible filter screen with a pore diameter of 5 μm. The inside bottom of the filter screen layer 17 is uniformly and spacedly provided with a plurality of first guide rollers 18 along the inner wall contour of the cylinder 13, and the inside top of the filter screen layer 17 is provided with a second guide roller 19. The first guide roller 18 and the second guide roller 19 can tightly press the filter screen layer 17 against the inner wall of the cylinder 13. The part of the filter screen layer 17 between the first guide roller 18 and the second guide roller 19 has a gap with the inner wall of the cylinder 13. The inner wall of the cylinder 13 is provided with an annular sealing groove 15 at the position corresponding to each group of through holes 14. The outer surface of the filter screen layer 17 is provided with a flexible sealing strip 16 at the position corresponding to each sealing groove 15. The cross-sectional shape of the sealing groove 15 and the sealing strip 16 is trapezoidal, and each sealing strip 16 can fill and close the sealing groove 15.

[0042] In the carding process, although the lint pieces after softening produce less fly lint, but it is still impossible to completely avoid the generation of fly lint. By arranging the filter screen layer 17, the fly lint sucked into the cylinder 13 can be filtered to avoid the blockage of the slits in the grid plate 21 and affect the recovery effect of the softening agent.

[0043] By arranging the first guide roller 18 and the second guide roller 19, the filter screen layer 17 can rotate together with the cylinder 13 during the rotation of the cylinder 13, so that the filter screen layer 17 between the first guide roller 18 and the second guide roller 19 is constantly replaced and updated. Compared with the fixed small-area filter screen, the service life is longer and the replacement frequency is lower.

[0044] At the same time, due to the arrangement of the sealing groove 15 and the sealing strip 16, the part of the filter screen layer 17 at the opening of the suction cavity box 20 can perform filtering work, and the remaining positions are closed due to the filling of the sealing strip 16 in the sealing groove 15, so that only the through holes 14 corresponding to the opening of the suction cavity box 20 can suck in air and softening agent, avoiding the excessive dispersion of the negative pressure generated by the suction cavity box 20, thereby improving the suction force to improve the recovery efficiency of the softening agent.

[0045] As shown in Figures 1-8 two shaft rods 38 are rotatably connected between the two end covers 12, a plurality of brush rollers 39 are fixedly connected to each shaft rod 38, each brush roller 39 is in contact with the inner wall of the cylinder 13 and the outer side surface of the filter screen layer 17, and a guide wheel 40 is rotatably connected to each shaft rod 38 at the position corresponding to each sealing strip 16, and each guide wheel 40 is in rolling connection with the corresponding sealing strip 16.

[0046] By setting the brush roller 39, the filter screen layer 17 can filter the lint entering the tin cylinder 13 while cooperating with the circulation operation of the filter screen layer 17 to brush the outer surface of the filter screen layer 17, so that the lint remaining on the surface of the filter screen layer 17 and in the pores of the through holes 14 is brushed and transferred to the brush roller 39, thereby avoiding the pores of the filter screen layer 17 and the through holes 14 from being blocked by the lint, further improving the service life of the filter screen layer 17, and by setting the guide wheel 40, the sealing strip 16 is guided and the filter screen layer 17 is tensioned without affecting the normal circulation operation of the filter screen layer 17, thereby avoiding the filter screen layer 17 from being deformed such as wrinkling.

[0047] As shown in Figures 1-8 The tin cylinder 13 is fixedly connected with a gear ring 35 at the inner wall of the end away from the air inlet 22, the first gear 33 is rotatably connected with the center of the end cover 12 close to the gear ring 35, a plurality of second gears 34 are in meshing transmission connection between the first gear 33 and the gear ring 35, the shaft center of the first gear 33 passes through the end cover 12, one end of each shaft rod 38 is fixedly connected with a third gear 37, each third gear 37 is in meshing transmission connection with the gear ring 35, one end of the second gear 34 and the first gear 33 is provided with a gear end cover 36 covering the first gear 33 and the second gear 34, and the gear end cover 36 is fixedly connected with the adjacent end cover 12.

[0048] By setting the first gear 33, the second gear 34 and the gear ring 35, the rotation of the tin cylinder 13 is driven, so that the cotton combing work can be carried out, and by setting the third gear 37 meshing with the gear ring 35, the rotation of the tin cylinder 13 drives the brush roller 39 to perform brushing action, and the transmission mode makes the tangent direction of the rotation of the brush roller 39 opposite to the running direction of the filter screen layer 17 at the contact position of the brush roller 39 and the filter screen layer 17, thereby improving the brushing effect of the brush roller 39 on the surface of the filter screen layer 17.

[0049] As shown in Figures 1-8 The rotating sealing ring 24 is arranged at the rotating connection between the end cover 12 and the tin cylinder 13, each end cover 12 is fixedly connected with a support 25, and each support 25 is fixedly connected above the cotton combing machine support 10.

[0050] By setting the rotating sealing ring 24, the sealing effect of the rotating connection between the tin cylinder 13 and the end cover 12 is improved, thereby avoiding the negative pressure from leaking at the rotating connection and improving the recovery efficiency of the softening agent, and when the airflow passes between the densely arranged grid plates 21, vibration is inevitable, and the support capacity of the end cover 12 can be improved by the support 25, effectively resisting the axial and radial vibration of the tin cylinder 13, so as to reduce the influence of vibration on the device.

[0051] In this embodiment, initially, the operator injects a sufficient amount of softening agent into the atomizer 28, and turns on the high-pressure fan 29 to generate a negative pressure suction in the suction chamber box 20, starts the device, the cotton raw material is pressed by the three-roller group 42 to form a sheet-shaped cotton-containing sheet, and is transferred to the surface of the cylinder 13 for carding. During the carding process, the atomizing sprayer 26 sprays the atomized softening agent to the cotton-containing sheet in the carding process, and finally the cotton-containing sheet after carding and softening treatment is transferred to the cylinder group 41, and finally is collected and discharged.

[0052] At the same time, the negative pressure suction at the suction chamber box 20 sucks the atomized softening agent that is not fully utilized into the cylinder 13 through the through hole 14, and after filtering through the filter screen layer 17, it enters the suction chamber box 20. After the atomized softening agent fully contacts the densely arranged grid plates 21, it gradually condenses into a liquid, and finally drops to the bottom of the suction chamber box 20 and returns to the atomizer 28 for reuse. The airflow generated by the high-pressure fan 29 in the suction chamber box 20 is directly discharged to the outside, which can carry away part of the uncondensed softening agent, but most of it will be condensed and recovered, reducing the waste of softening agent.

[0053] While the cylinder 13 is rotating and carding, due to the friction between the sealing groove 15 and the sealing strip 16, the filter screen layer 17 moves with the cylinder 13, so that the filter screen layer 17 at the working position is constantly replaced, and the large-area filter screen layer 17 can be fully and uniformly utilized. At the same time, the brush roller 39 synchronously brushes the surface of the filter screen layer 17 to avoid the blockage of the pores of the filter screen layer 17 by flying lint, and the flying lint is retained in the gap between the filter screen layer 17 and the cylinder 13. Since the brush roller 39 constantly brushes the surface of the filter screen layer 17 and the amount of flying lint after softening treatment is small, the retained flying lint does not easily affect the filtering or recovery of the softening agent in a long working time.

[0054] After a long time of work, the amount of retained flying lint accumulates and can have adverse effects. At this time, the device can be disassembled and maintained to remove the flying lint and replace the worn-out parts such as the filter screen layer 17 and the brush roller 39.

[0055] The main body of the device is a three-roller carding machine, and the existing structures such as the circulating carding cover plate and the feeding roller are not directly related to the scheme of the present application, so they are not shown in the present application. The atomizer 28, the high-pressure fan 29, and the liquid pump 31 are mature existing technologies, and the structures in the drawings are only schematic, and will not be described in detail herein.
