Description

Technical Field

[0001] This invention relates to the field of textile production technology, specifically to a process for producing vortex-spun recycled cotton blended colored yarn. Background Technology

[0002] With the continuous improvement of environmental awareness, the environmental protection industry has ushered in a golden age of rapid development. As people's awareness of environmental protection increases, the demand for environmentally friendly products is also constantly growing. China's recycled cotton yarn industry is an emerging industry that is developing rapidly and vigorously. It plays an important role in promoting green and environmentally friendly development and contributing to the harmonious development of China's economy and society.

[0003] In a prior art Chinese invention patent with publication number CN111575859A, a method for recycling waste cotton textiles into blended yarns was proposed. Specifically, it was proposed that the method includes "a crusher box, a collection device connected to the crusher box, a mounting frame, and a circulating separation disc fixedly mounted on the mounting frame".

[0004] The aforementioned prior art also has the following defects: In the above device, the recycled material is crushed by the crushing blade, and the bottom cylinder air pressure plate blows the crushed cotton upwards, causing the cotton to gather in the fiber transport pipe. The inventors found that the blowing direction of the bottom cylinder air is inconsistent with the direction of the cotton, resulting in a large amount of cotton being scattered in the air. Here, we propose a vortex spinning process for producing blended colored yarn from recycled cotton. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies. This invention features a discharge port at the lower end of one side of a storage cylinder, a discharge tube at the center of the storage cylinder, several through holes distributed around the lower periphery of the discharge tube, a rotating shaft in the middle of the discharge tube, and a motor at the bottom of the storage cylinder. The motor output drives the rotating shaft via a belt. The discharge tube is divided into crushing chamber a and crushing chamber b by a screen plate. Each crushing chamber a and crushing chamber b contains several crushing blades a and b, respectively. A vibration assembly is located at the lower end of the screen plate to filter the pre-crushed material. An air-blowing assembly is located at the upper end of the discharge tube. The outer circumference of the discharge tube... An adsorption component is arranged in a circumferential direction to adsorb cotton fibers blown out from the feeding cylinder. The outer surface of the adsorption component is equipped with a cleaning component for removing long fibers. A drive component is arranged at the top of the storage cylinder and linked to the rotating shaft. The drive component is used to drive the adsorption component to rotate. In this invention, the adsorption component adsorbs the cotton fibers after secondary crushing. Long cotton fibers that are not completely crushed are processed and recycled by the cleaning component. The completely crushed cotton fibers enter the next process through the discharge port. The process in this invention is complete and highly automated, avoiding the steps that require manual operation in conventional equipment, thus improving work safety and production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1

[0039] Reference Figure 1-9 A process for producing recycled cotton blended colored yarn using vortex spinning includes a support frame 1 and a storage cylinder 2 mounted on the support frame 1. A discharge port 3 is located at the lower end of one side of the storage cylinder 2. A feeding cylinder 4 is located at the center of the storage cylinder 2. Several through holes 5 are distributed around the lower periphery of the feeding cylinder 4. A rotating shaft 6 is located in the middle of the feeding cylinder 4. A motor 7 is located at the bottom of the storage cylinder 2. The output of the motor 7 drives the rotating shaft 6 to rotate via a belt 8. The interior of the feeding cylinder 4 is divided into a crushing chamber a10 and a crushing chamber b11 by a screen plate 9. The device is equipped with several crushing fan blades a12 and b13. A vibration assembly 14 is provided at the lower end of the screen plate 9. An air blowing assembly 15 is provided at the upper end of the feeding cylinder 4. An adsorption assembly 16 is provided around the outer ring of the feeding cylinder 4. A cleaning assembly 17 for removing long fibers is provided on the outer surface of the adsorption assembly 16. The adsorption assembly 16 is used to adsorb cotton fibers blown out from the feeding cylinder 4. A drive assembly 18 is provided at the top of the storage cylinder 2 and is linked to the rotating shaft 6. The drive assembly 18 is used to drive the adsorption assembly 16 to rotate.

[0040] Reference Figure 5The vibration assembly 14 includes a groove 141 in the middle of the rotating shaft 6, a support rod 142 at the bottom of one side of the screen plate 9, a circular column 143 at the bottom of the support rod 142, and a guide rail 144 abutting against the circular column 143.

[0041] Reference Figure 5 The guide rail 144 includes a raised section 1441 and a parallel section 1442, which are connected in an arc shape.

[0042] It is worth mentioning that the circular column 143 slides on the guide rail 144, causing the screen plate 9 to vibrate up and down in the groove 141, thereby vibrating and filtering the material.

[0043] Reference Figure 6 The air blowing assembly 15 includes an air pipe 151 that penetrates the top surface of the feeding cylinder 4 and the storage cylinder 2, air distribution pipes 152 distributed along the circumferential direction of the air pipe 151, a number of elongated through slots 153 connected to the air pipe 151 at the lower end of the rotating shaft 6, and a number of arc-shaped through slots 154 distributed around the crushing fan blade b13.

[0044] In this embodiment, by filling the air pipe 151 with gas, a portion of the gas passes through the middle of the rotating shaft 6 and blows the material after secondary crushing to the periphery of the feeding cylinder 4 through the elongated through groove 153 and the arc-shaped through groove 154. Another portion of the gas flows out from the air distribution pipe 152, and the cotton lint without adsorption force on the outside of the adsorption roller 161 is blown downwards.

[0045] Reference Figure 7 The adsorption assembly 16 includes an adsorption roller 161 rotatably disposed at the bottom of the storage cylinder 2, air holes 162 distributed around the adsorption roller 161, a negative pressure pump 163 disposed at the upper end of the storage cylinder 2, a negative pressure pipe 164 connecting the negative pressure pump 163 and the adsorption roller 161, and an arc-shaped baffle 165 fixedly disposed at the bottom of the storage cylinder 2 and in contact with the inner wall of the adsorption roller 161.

[0046] It is worth mentioning that the negative pressure suction of the part blocked by the arc-shaped baffle 165 allows the air blown downward by the branch pipe 152 to carry the short cotton wadding, thus separating the long cotton wadding from the short cotton wadding.

[0047] Reference Figure 7 The inner wall of the adsorption roller 161 is covered with a filter screen, and the diameter of the air hole 162 is smaller than the diameter of the through hole 5.

[0048] In this embodiment, by providing a filter screen on the inner wall of the adsorption roller 161, it is possible to prevent the adsorption roller 161 from sucking in fine cotton fibers.

[0049] Reference Figure 8The cleaning assembly 17 includes a collar 171 disposed on the outer ring of the adsorption roller 161, a sliding rod 172 disposed at the lower end of the collar 171, a cylinder 173 for driving the sliding rod 172, an inclined surface a174 disposed on the periphery of the lower end of the collar 171, a plurality of arc-shaped grooves 175 disposed at the bottom of the storage cylinder 2 and located on the periphery of the adsorption roller 161, a cavity 176 formed in the inner wall of the arc-shaped grooves 175, a baffle 177 slidably disposed in the cavity 176, an inclined surface b178 disposed on the front end face of the baffle 177, and a return spring 179 disposed on the rear end face of the baffle 177.

[0050] It is worth mentioning that by the inclined surface a174 on the collar 171 abutting against the inclined surface 178 on the baffle 177, the collar 171 presses down to squeeze the baffle 177 to the periphery, which can clean up the excessively long cotton fibers. At the same time, the reset spring 179 at the tail end of the baffle 177 can drive it to reset, so that the lower end face of the storage cylinder 2 is resealed.

[0051] Reference Figure 7 The drive assembly 18 includes a gear a181 disposed at the upper end of the rotating shaft 6, a gear b182 meshing with the gear a181, and a gear c183 meshing with the gear b182, and the gear c183 is disposed on the upper surface of the adsorption roller 161.

[0052] It is worth mentioning that the gear c183 on the negative pressure roller 161 meshes with its adjacent gear c183, which can drive multiple negative pressure rollers 161 to rotate synchronously.

[0053] The number of blades in the broken fan blade b13 is greater than the number of blades in the broken fan blade a12.

[0054] Example 2

[0055] A process for producing vortex-spun recycled cotton blended colored yarn includes the following steps:

[0056] Step 1: Loosening. The recycled fabric is loosened by the corner nails and beaters in each unit of the opening and cleaning cotton machine. The blocky fibers are loosened into small cotton bundles weighing 0.3-0.5g. At the same time, impurities in the recycled cotton are removed.

[0057] Step 2: Combining and carding. Cotton fibers and chemical fibers are fully mixed according to the blending ratio. The mixed cotton fibers are then output to the cotton storage boxes of each carding machine in the carding process to form sliver.

[0058] Step 3: Drawing. The carded slivers are drawn together, and the slivers produced by the drawing machine are placed in regular loops inside the sliver can.

[0059] Step 4: Yarn Formation. The sliver produced by drawing is condensed and twisted in a high-speed rotating spinning cup using airflow to form yarn.

[0060] The work process is as follows:

[0061] The motor 7 is started, and the rotating shaft 6 is driven to rotate via the belt 8. This causes the crushing blades a12 and b13 to rotate inside the feeding cylinder 4 to crush the material. The crushed material falls onto the screen plate 9, which is filtered by the vibration on the guide rail 144 and falls into the crushing chamber b11. Gas is introduced into the air pipe 151. Part of the gas passes through the middle of the rotating shaft 6 and blows the secondary crushed material to the periphery of the feeding cylinder 4 through the long through groove 153 and the arc through groove 154. The other part of the gas flows out from the air distribution pipe 152, and the cotton fibers on the outside of the adsorption roller 161 that have no adsorption force are blown downwards.

[0062] Start the negative pressure pump 163, and draw out the air in the adsorption roller 161 through the negative pressure pipe 164 to adsorb the cotton lint blown out from the four sides of the feeding cylinder. The arc-shaped baffle 165 inside the adsorption roller 161 blocks the negative pressure inside. The air blown down through the air distribution pipe 152 can blow off the short cotton lint, while the long cotton lint continues to wrap around the negative pressure roller 161.

[0063] The cylinder 173 is activated, which moves the sliding rod 172 up and down to reset it. The collar 171 descends to clean the cotton lint from the outer ring of the negative pressure roller 161. Through the cooperation of inclined plane a174 and inclined plane b178, the baffle 177 can be pushed open towards the periphery of the cavity 176 to clean the cotton lint.

[0064] Of course, those skilled in the art should understand that the term "a" should be understood as "at least one" or "one or more". That is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple. The term "a" should not be understood as a limitation on the quantity.

[0065] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
