Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment, and particularly relates to a carding device that saves energy and improves quality. Background Art
[0002] The main working parts of a carding machine include the feed plate, cotton box, licker-in, cylinder, and doffer. When the raw fibers enter the carding machine, they are first subjected to negative pressure and the action of the upper cotton box, which removes short fibers. Next, the feed rollers of the lower cotton box feed the cotton layer to the licker-in, which further loosens the raw materials into fluffy fibers. These preliminarily loosened fibers are then fed to the cylinder, which works with the fixed and movable flats to finely comb and align the fibers and remove any remaining impurities. The combed fiber bundles are then condensed into slivers, which are finally discharged from the carding machine.
[0003] Currently, most carding machines have short upper bins, which store relatively little fiber. During production, a significant amount of negative pressure is required to compact the cotton inside the bin and stabilize the lower cotton. Otherwise, the cotton becomes loose and the layer becomes fractured, severely impacting production quality. This high negative pressure also requires high-powered fans for both cotton feeding and dust removal over long distances, resulting in high energy consumption and difficulty controlling the stability of the entire process, leading to inconsistent fiber product quality.
[0004] This patent invents a lengthened upper cotton box device that can mechanically increase the negative pressure of the cotton box and reduce energy consumption. Utility Model Content

[0014] Beneficial effects of the utility model:
[0015] First, the present invention proposes a carding device with an adjustable cotton box, which increases the amount of cotton stored in the cavity formed by the adjustable cotton box and the upper cotton box, thereby increasing the pressure in the upper cotton box. This can make the cotton feeding roller feed more uniform, thereby making the cotton layer in the lower cotton box more stable and improving the carding quality. At the same time, the carding device is also provided with a bypass pipe to avoid the problem of wind being unable to enter the dust removal pipe normally due to the surface layer after the adjustable cotton box is filled. In the entire device, the bypass pipe can be used to release the pressure in the cotton feeding pipe, making the cotton feeding pipe more smooth and reducing pipe blockage.
[0016] Second, in this utility model, flanges are provided at the ends of the adjustable cotton box and the upper cotton box, as well as at the through-hole of the cotton feeding tube. The adjustable cotton box is detachably connected to the upper cotton box and the through-hole of the cotton feeding tube respectively via flanges and fasteners. This allows for the installation of adjustable cotton boxes of different specifications as needed to suit different production scenarios. Furthermore, this structural design facilitates assembly, processing, and equipment maintenance.
[0017] 3. In this utility model, the height of the cotton box should be selected / designed according to the working pressure of the equipment, and is generally controlled within 20-50m. Preferably, the inner diameter of the cotton box should be adjusted to be equal to that of the upper cotton box to avoid fiber accumulation at the connection between the components, which may affect product quality.
[0018] Fourth, in this utility model, a filter screen I is installed at the connection between the regulating cotton box and the bypass duct, and a filter screen II is installed at the connection between the negative pressure suction channel and the upper cotton box. This can prevent fibers in the regulating cotton box from entering the air duct through the bypass duct and the negative pressure suction channel, affecting the normal operation of the equipment.

[0040] Example 6
[0041] The difference between this embodiment and embodiments 1 to 5 is that both filter screen I 12 and filter screen II 13 are 200-mesh filter screens.
[0042] Example 7
[0043] In order to facilitate the public to understand the present solution, this embodiment is taken as an example of a better implementation method. The energy-saving and quality-improving carding device includes two carding machine bodies 3, which will be further explained in conjunction with the accompanying drawings.
[0044] refer to Figures 1 to 4 , 6. The carding device also includes a cotton feeding tube 1 and a dust removal tube 2. An upper cotton box 4 is installed on the carding machine body 3. The lower end of the upper cotton box 4 is connected to the lower cotton box 5. A cotton feeding roller 6 is provided near the inlet of the lower cotton box 5. A through hole 1.1 is provided on the tube wall of the cotton feeding tube 1. The upper port of the upper cotton box 4 is connected to the through hole 1.1 of the cotton feeding tube 1 through an adjusting cotton box 7. The adjusting cotton box 7 is connected to the dust removal tube 2 through a bypass pipe 8. The dust removal tube 2 is connected to the upper cotton box 4 through a negative pressure suction channel 9. The cotton feeding tube 1 also includes a feeding port 1.2 and a discharging port 1.3. Figure 1 In the figure, a represents the material conveying channel; b represents the air duct.
[0045] In this embodiment, flanges 10 are provided at the ends of the adjusting cotton box 7, the upper cotton box 4, and the through hole 1.1 of the cotton feeding tube 1. The adjusting cotton box 7 is detachably connected to the upper cotton box 4 and the through hole 1.1 of the cotton feeding tube 1 through the flanges 10 and fasteners 11.
[0046] In this embodiment, the height of the adjustable cotton box 7 is 30 cm. The inner diameter of the adjustable cotton box 7 is equal to that of the upper cotton box 4.
[0047] In this embodiment, a filter screen I 12 is provided at the connection between the regulating cotton box 7 and the bypass pipe 8, and a filter screen II 13 is provided at the connection between the negative pressure suction channel 9 and the upper cotton box 4. Both the filter screen I 12 and the filter screen II 13 are 200-mesh filters.
[0048] In this embodiment, an adjusting cotton box 7 is designed. When the device is in operation, the amount of cotton stored above the upper cotton box 4 increases, that is, the amount of cotton stored in the chamber formed by the adjusting cotton box 7 and the upper cotton box 4 increases, thereby increasing the pressure of the upper cotton box 4, which can make the cotton feeding roller 6 feed cotton more evenly, make the cotton layer of the lower cotton box 5 more stable, and improve the combing quality.
[0049] When designing the height of the adjustable cotton box 7, it is important to consider pressure settings and cotton delivery and exhaust. For example, in this solution, with a 31-meter-long cotton delivery tube 1, before the adjustable cotton box 7 is used, the pressure in the cotton delivery tube 1 is approximately 1100 Pa, and the dust removal negative pressure is approximately 1000 Pa. The pressure in the cotton delivery tube 1 should be slightly greater than that in the dust removal tube 2 to ensure adequate pressure in the cotton box. With the adjustable cotton box 7, the pressure in the cotton delivery tube 1 can be set to 900 Pa, and the dust removal pressure can be set to 800 Pa, which also reduces energy consumption in the carding unit.
[0050] When the combing device is in operation, the cotton regulating box 7 may fill up, and due to the cotton layer, the wind cannot normally enter the dust removal pipe 2. In this case, the bypass pipe of the device can effectively solve this problem, and the pressure can be released through the cotton feeding pipe 1. The bypass pipe connects the cotton regulating box 7 and the dust removal pipe 2. A 200-mesh filter is also installed at the connection between the cotton regulating box 7 and the bypass pipe to filter the fibers, allowing only the cotton feeding air to be discharged. In this way, the added bypass pipe makes the cotton feeding of the cotton feeding pipe 1 smoother and reduces the risk of pipe blockage.
[0051] The use of this carding device can not only reduce energy consumption, but also achieve longer distance material transmission under the same negative pressure. When transmitting materials over the same distance, energy consumption can be reduced, and tighter cotton box pressure can be achieved under the same negative pressure, thereby obtaining a better cotton layer and better carding quality.
