Description

Technical Field

[0001] This invention belongs to the field of washing machine technology, specifically relating to a bio-based nylon fabric washing machine and washing process. Background Technology

[0002] Rope washing machines are core equipment in the dyeing and finishing industry for washing knitted fabrics and elastic fabrics. Their core working method is to gather the fabric into a loose rope shape and remove dirt and lint by immersion and water rinsing under low tension. They also have the advantages of preventing fabric stretching and deformation and being compatible with a variety of fabrics.

[0003] Chinese patent CN216237690U discloses a high-efficiency and energy-saving rope washing machine, including a rope washing machine body, a filter assembly, and a return assembly. A fixed box is fixedly installed at the bottom of the rope washing machine body. The filter assembly includes a filter box located in the middle of the bottom of the rope washing machine body. A filter screen is fixedly installed on the left side inside the filter box, and a chemical dosing hopper is fixedly installed in the middle of the front of the filter box. The return assembly includes a guide pump and a return pump. This high-efficiency and energy-saving rope washing machine, by setting up the filter assembly and the return assembly, allows the guide pump to guide the wastewater generated during the operation of the rope washing machine body into the interior of the filter box via a guide pipe and the guide pump. After treatment, the wastewater, after being filtered through the filter screen, is guided by the return pump through a second connecting pipe and the return pipe back to the water inlet of the rope washing machine body, realizing wastewater reuse and achieving energy saving and environmental protection.

[0004] However, the above technical solution has a key technical pain point in actual operation: after the fabric is gathered into a rope shape, it is prone to local compaction under slight traction tension. This causes the lint and loose fibers attached to the fabric surface to be trapped inside the rope core, which cannot be fully exposed to the washing liquid and rinsing water flow, and thus cannot be effectively washed away. This not only affects the cleaning effect of the fabric, but the residual lint may also re-attach to the fabric surface in subsequent processes, affecting product quality. Summary of the Invention

[0005] The purpose of this invention is to provide a bio-based nylon fabric washing machine and washing process, which aims to solve the problems in the prior art where rope-like fabrics are easily compacted during the impregnation process and lint is trapped inside the rope core and cannot be effectively removed.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bio-based nylon fabric washing machine, comprising: a washing machine body and a plurality of impregnation baskets installed inside the washing machine body, further comprising: a rotating drum rotatably installed inside the impregnation baskets, the rotating drum being horizontally arranged; an auger structure consisting of two symmetrically arranged auger blades with opposite spiral directions, a ring being fixedly provided between the two auger blades, which can drive the fabric draped thereon to unfold when the auger structure rotates with the rotating drum; and a driving device installed on the washing machine body and used to drive the rotating drum to rotate.

[0007] A further technical solution of the present invention includes an anti-deviation structure, which is installed in the impregnation basket and is used to detect the deviation of the fabric on the auger structure and drive the auger structure to correct the deviation of the fabric.

[0008] A further technical solution of the present invention is that the anti-deviation structure includes a sliding rod slidably disposed inside the impregnation basket. The sliding rod is located directly below the auger structure, and the sliding direction is consistent with the axis of the rotating drum. A swing frame is disposed on the sliding rod, and a rotating ring is disposed on the swing frame. The circumference of the ring is provided with a groove, and the rotating ring is rotatably disposed in the groove. There are two symmetrically arranged support rods on the swing frame, and each support rod is provided with a roller. When the fabric deviates to one side, the rollers and the support rods drive the swing frame, the rotating ring, and the auger structure to slide in the direction of deviation.

[0009] A further technical solution of the present invention is that the spiral diameter of the auger plate gradually and uniformly decreases from one end near the ring to the other end, so that when the middle part of the fabric is placed on the ring, it is in a state where the middle part is raised and the two sides are lower than the middle part.

[0010] A further technical solution of the present invention is that the auger structure and the rotating drum are separately configured, the auger structure can slide along the axial direction of the rotating drum, the outer surface of the rotating drum is provided with an axially extending groove, and the auger structure is provided with a slider that slides in cooperation with the groove.

[0011] A further technical solution of the present invention is that a rinsing pipe is installed above each of the impregnation baskets, and the rinsing pipes are provided with nozzles facing the auger structure, and the rinsing pipes are connected to each other through a transfer pipe.

[0012] A further technical solution of the present invention is that two sleeves are rotatably arranged on the flushing pipe, with the ends of the two sleeves close to each other located directly above the rotating ring, and a first friction disc fixed at the end of each sleeve away from each other, and a second friction disc corresponding to and cooperating with the first friction disc at both ends of the auger structure.

[0013] A further technical solution of the present invention is that the first friction disc is semi-circular, and a limiting block is provided on the impregnation basket. The limiting block is located above the horizontal plane of the first friction disc and is used to limit the rotation angle of the first friction disc. An opening is provided on the sleeve, and an inclined surface is provided on one side of the opening. When the first friction disc rotates to abut against the limiting block, the inclined surface switches to directly below the nozzle.

[0014] A bio-based nylon fabric washing process includes the following steps: S1. Drop the fabric vertically from the fabric drop opening of the washing machine body into the immersion basket, and pre-open the fabric and place it on the auger structure so that the middle of the fabric is close to the ring. S2. Start the drive device, which drives the auger structure to rotate through the rotating drum. The two auger plates with opposite spiral directions spread the fabric laterally from the middle to both sides. S3. The unfolded fabric falls back into the impregnation liquid as the auger structure rotates, and the impregnation liquid washes and cleans the lint on the surface of the unfolded fabric; at the same time, the rinsing pipe sprays the impregnation liquid onto the fabric on the auger structure through the nozzle to assist in rinsing the lint. S4. When the fabric shifts and accumulates on one side, the anti-deviation structure senses the direction of deviation through the rollers and drives the auger structure to slide in the direction of deviation, so that the pitch of the auger plate on the deviation side is reduced, and the auger plate on the other side pulls the fabric in the opposite direction of deviation with a larger conveying step distance to correct the deviation. S5. When the auger structure slides to the extreme offset position, the second friction disc on the offset side engages with the first friction disc, causing the sleeve to deflect and the inclined surface to switch to below the nozzle. The guide impregnation liquid reduces the friction of the fabric on the offset side, assisting the auger structure to stretch the piled fabric to the opposite side and complete the automatic correction. S6. The drive device periodically controls the auger structure to reverse, so that the auger plates on both sides gather the fabric towards the center, and rubs and washes the fabric through the relative movement of the auger plates and the fabric. S7. After washing, the fabric is pulled into the next process by the lifting wheel.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. By synchronously rotating two auger blades with opposite spiral directions, the fabric, which was originally gathered into a rope shape and easily compacted, is laterally unfolded from the center to both sides. After the fabric is unfolded, the lint and loose fibers that were originally trapped inside the rope core are fully exposed, allowing the impregnation liquid to directly contact and wash away these impurities. At the same time, the increased surface area of ​​the flattened fabric significantly enhances the penetration and rinsing effect of the water flow when it falls back into the impregnation liquid from the auger structure. This solves the problem of traditional rope-type washing machines "not being able to wash the core" and effectively avoids product quality problems caused by residual lint re-adhering to the fabric surface in subsequent processes.

[0016] 2. By setting up an anti-deviation structure composed of rollers, support rods, slide rods, and a swing frame, the mechanical signal of fabric deviation is directly converted into the axial displacement of the auger structure. When the fabric shifts and accumulates on one side, the roller on the shifted side is forced to slide the entire auger structure to the same side, reducing the pitch of the auger blades on that side. The auger blades on the opposite side maintain their original pitch and stretch the fabric in the opposite direction with a larger conveying step, ensuring that the fabric is always washed in a flat state and eliminating the problem of local lint removal failure caused by fabric accumulation on one side.

[0017] 3. The drive device can periodically control the auger structure to reverse. When reversing, the auger plates on both sides gather the fabric towards the center, and the relative movement between the auger plates and the fabric acts as a rubbing action. This makes the same auger structure act as a "flatter" when rotating forward, opening the fabric laterally to expose the lint; and as a "rubbing device" when rotating in reverse, simulating the action of hand washing to deeply clean the inside of the fabric fibers.

[0018] 4. When the auger structure slides to the extreme offset position, the second friction disc on the offset side engages with the first friction disc, causing the sleeve to deflect and switch the inclined surface to below the nozzle, guiding the impregnating liquid to the outside of the fabric on that side, reducing the friction between the fabric on that side and the auger plate; at the same time, the nozzle on the other side continues to spray directly onto the fabric surface, maintaining a large friction force. This passive auxiliary correction mechanism is achieved by utilizing the impact difference of the water flow and the friction difference, without the need for additional power.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-7 The present invention provides the following technical solution: a bio-based nylon fabric washing machine, comprising a washing machine body 1, an impregnation basket 2, a flattening structure 3 and an anti-deviation structure 4.

[0023] The impregnation basket 2 is installed inside the washing machine body 1 and is evenly arranged along the length of the washing machine body 1. The fabric 5 falls vertically into the impregnation basket 2 from the top fabric drop opening 11 of the washing machine body 1. The washing machine body 1 is filled with impregnation liquid, which enters the interior of the impregnation basket 2 through multiple through holes on the impregnation basket 2. The impregnation liquid impregnates the fabric 5. At the same time, the fabric 5 moves under the action of the fabric lifting wheel (not shown in the figure). The flattening structure 3 is installed inside the impregnation basket 2, so that the fabric 5 is placed on the flattening structure 3 and unfolded. The unfolded fabric 5 is sent back into the impregnation liquid from the flattening structure 3 to rinse and clean the lint on the surface of the fabric 5. The anti-deviation structure 4 is installed inside the impregnation basket 2. When the fabric 5 deviates to one side on the auger structure 32, it will cause the fabric 5 to accumulate to one side, resulting in poor lint cleaning effect. Therefore, by setting the anti-deviation structure 4, the fabric 5 is prevented from deviating too much, thereby improving the lint cleaning effect.

[0024] Please see Figures 2-5The flattening structure 3 includes a rotating drum 31 rotatably installed inside the impregnation basket 2. The rotating drum 31 is horizontally positioned, with both ends extending through the vertical sides of the impregnation basket 2. An auger structure 32 is mounted on the rotating drum 31. When the rotating drum 31 rotates, it drives the auger structure 32 to rotate. The auger structure 32 includes two symmetrically arranged auger blades 321 with opposite spiral directions (one left-handed and the other right-handed). The two auger blades 321 are connected by a ring 322 and are integrally formed. A drive device 33 is mounted on the washing machine body 1. The output end of the drive device 33 extends into the interior of the washing machine body 1 and is connected to the rotating drum 31. The rotating drums 31 within each impregnation basket 2 are connected by a transmission device 34, allowing multiple rotating drums 31 to rotate synchronously. This transmission device 34 can be a gear mesh or a coupling to achieve synchronous rotation of multiple rotating drums 31. First, the fabric 5 is pre-opened and draped over the auger structure 32, with the center of the fabric 5 as close as possible to the ring 322. Then, the drive device 33 drives one of the rotating drums 31 to rotate, and the transmission device 34 drives multiple rotating drums 31 to rotate synchronously. When the rotating drums 31 rotate, they drive the auger structure 32 to rotate synchronously. The rotation of the auger structure 32 causes the two auger blades 321 to rotate. Since the spiral directions of the two auger blades 321 are opposite, the auger blades 321 can unfold the fabric 5 from the center to the side. The unfolded fabric 5 falls back into the impregnation liquid through the rotation of the auger structure 32, allowing the impregnation liquid to clean the lint on the surface of the fabric 5. When the auger structure 32 reverses, the auger blades 321 on both sides will gather the fabric 5 towards the center. At the same time, through the relative movement of the auger blades 321 and the fabric 5, a certain rubbing effect can be achieved on the fabric 5, improving the cleaning effect of the fabric 5.

[0025] Please see Figures 4-6The spiral diameter of the auger plate 321 changes linearly, gradually decreasing uniformly from one end near the ring 322 to the other. Therefore, when the fabric 5 is draped over the auger structure 32, the middle of the fabric 5 is raised, while the two sides are lower than the middle. This makes it easier for the auger plate 321 to spread the fabric 5 when rotating. A rinsing pipe 6 is installed above each impregnation basket 2, and the rinsing pipe 6 has nozzles 61 facing the auger structure 32. Each rinsing pipe 6 is connected to the others via a connecting pipe 62, allowing multiple rinsing pipes 6 to be connected within the washing machine body. An external water pump (not shown in the figure) is installed to inject impregnation liquid into the flushing pipe 6. The impregnation liquid is sprayed onto the fabric 5 on the auger structure 32 through the nozzle 61. Since the fabric 5 is in an unfolded state on the auger structure 32, most of the lint can be washed off in advance when the nozzle 61 sprays the impregnation liquid onto the fabric 5. In addition, the impact force of the impregnation liquid sprayed from the nozzle 61 on the fabric 5 makes the fabric 5 stick to the auger structure 32 more tightly, effectively avoiding the situation where the auger structure 32 slips on the bottom of the fabric 5, and avoiding the problem that the auger structure 32 is difficult to move the fabric 5.

[0026] Please see Figures 5-7 The anti-deviation structure 4 includes a sliding rod 41 installed inside the impregnation basket 2. The two ends of the sliding rod 41 are slidably mounted on the vertical side walls of the impregnation basket 2, and the sliding rod 41 is located directly below the auger structure 32. The sliding direction of the sliding rod 41 is consistent with the axial direction of the rotating drum 31. A swing frame 42 is fixedly connected to the sliding rod 41. The swing frame 42 includes a rotating ring 421. A ring groove 43 is provided in the circumferential direction of the ring 321. The rotating ring 421 rotates inside the groove 43, and the axial movement of the rotating ring 421 is restricted by the groove 43. The auger structure 32 and... The rotating drums 31 are designed as separate units, allowing the auger structure 32 to slide axially on the outer surface of the rotating drums 31. An axially extending groove 44 is formed on the outer surface of the rotating drums 31. A slider 45, capable of sliding within the groove 44, is provided on the auger structure 32. Two support rods 46, which are elastic telescopic rods, are also provided on the swing frame 42. Rollers 47 are mounted on the support rods 46. The two support rods 46 and the rollers 47 are symmetrically arranged on both sides of the rotating drums 31. The middle of the fabric 5 rests on the two rollers 47 and the auger structure 32 (e.g., ...). Figure 7As shown), during use, when the fabric 5 shifts to one side on the auger structure 32, it will cause the fabric 5 to accumulate on one side. At this time, the nozzle 61 cannot effectively clean the lint at the accumulation position of the fabric 5. Therefore, when the fabric 5 shifts, the roller 47 and the support rod 46 will drive the rotating ring 421 and the slide rod 41 to move in the direction of shift. The movement of the rotating ring 421 will drive the auger structure 32 to move in the direction of shift, so that the auger plate 321 on the side closer to the shift direction abuts against the inner wall of the impregnation basket 2 and compresses the auger plate 321. After the auger plate 321 on this side is compressed, the pitch of the auger plate 321 on the other side remains unchanged, and finally the pitch of the auger plate 321 on the shift side is smaller than that of the auger plate 321 on the other side. When the two sets of auger blades 321 rotate synchronously, the auger blade 321 that is away from the offset direction has a larger conveying step distance, which can stretch and unfold the fabric 5 in the opposite offset direction more quickly, thereby effectively avoiding the accumulation of fabric 5 on one side and ensuring the normal progress of lint cleaning operation.

[0027] Two sleeves 7 are rotatably mounted on the rinsing pipe 6. The two sleeves 7 are of the same length and are positioned close to each other directly above the rotating ring 421. A first friction disc 71 is fixed to each end of the two sleeves 7 at their opposite ends. The auger structure 32 also includes second friction discs 323 located at both ends. In its natural state, there is a gap between the first friction disc 71 and the second friction disc 323. When the auger structure 32 slides to one side, the first friction disc 71 on one side contacts the second friction disc 323. When the auger structure 32 rotates, the second friction disc 323 causes the first friction disc 71 to rotate through friction. The first friction disc 71 is semi-circular, and a limiting block 21 is provided on the impregnation basket 2. The limiting block 21 is located above the horizontal plane of the first friction disc 71, making... After rotating a certain angle, the plane of the first friction disc 71 can abut against the limiting block 21, thereby limiting the rotation angle of the first friction disc 71. The sleeve 7 has an opening 72, and one side of the opening 72 is provided with an inclined surface 73. When the first friction disc 71 abuts against the limiting block 21, the impregnating liquid sprayed from the nozzle 61 will flow to the inclined surface 73, and the impregnating liquid will be guided to the surface of the fabric 5 outside the auger structure 32 through the inclined surface 73. In use, when the fabric 5 accumulates to the left, the auger structure 32 moves to the left as a whole, and the first friction disc 71 and the second friction disc 323 on the left side abut against each other. At the same time, the auger plate 321 on the left side is compressed. The auger plate 321 in the compressed state pushes the second friction disc 323, so that it applies a pressing force to the first friction disc 71, thereby increasing the friction between the two. When the auger structure 32 rotates, the second friction disc 323 drives the first friction disc 71 to rotate synchronously by relying on frictional resistance, so that the horizontal end face of the first friction disc 71 abuts against the limiting block 21 for limiting. The rotation of the first friction disc 71 causes the left sleeve 7 to deflect at a certain angle, switching the inclined surface 73 directly below the nozzle 61. At this time, the impregnating liquid sprayed from the nozzle 61 is guided by the inclined surface 73 and flows to the fabric 5 on the outer left side of the auger structure 32, effectively reducing the scouring and impact of the impregnating liquid on the fabric 5 on the left side of the auger structure 32 and reducing the friction between the left side of the auger structure 32 and the fabric 5. The right sleeve 7 remains fixed and does not rotate. The impregnating liquid from the right nozzle 61 is directly sprayed onto the surface of the fabric 5 on the upper right side of the auger structure 32, making the friction between the fabric 5 on the right side of the auger structure 32 greater than that on the left. Therefore, during rotation, the auger structure 32 more easily pulls the fabric 5 to the right, thus fully unfolding the fabric 5 piled on the left side and correcting its deviation. The first friction disc 71 has a certain weight, which allows the sleeve 7 to return to its original position.

[0028] A bio-based nylon fabric washing process includes the following steps: S1. Drop the fabric 5 vertically from the fabric drop opening 11 of the washing machine body 1 into the soaking basket 2, and pre-open the fabric 5 and place it on the auger structure 32, so that the middle part of the fabric 5 is close to the position of the ring 322. S2. Start the drive device 33, drive the auger structure 32 to rotate through the rotating drum 31, and the two auger plates 321 with opposite spiral directions will spread the fabric 5 laterally from the middle to both sides. S3. The unfolded fabric 5 falls back into the impregnation liquid as the auger structure 32 rotates. The impregnation liquid washes and cleans the lint on the surface of the unfolded fabric 5. At the same time, the rinsing pipe 6 sprays the impregnation liquid onto the fabric 5 on the auger structure 32 through the nozzle 61 to assist in rinsing the lint. S4. When the fabric 5 shifts and accumulates on one side, the anti-deviation structure 4 senses the deviation direction through the roller 47 and drives the auger structure 32 to slide in the deviation direction, so that the pressure pitch of the auger plate 321 on the deviation side decreases, and the auger plate 321 on the other side pulls the fabric 5 in the opposite deviation direction with a larger conveying step distance to correct the deviation. S5. When the auger structure 32 slides to the extreme offset position, the second friction disk 323 on the offset side engages with the first friction disk 71, causing the sleeve 7 to deflect so that the inclined surface 73 switches to below the nozzle 61. The guide impregnation liquid reduces the friction of the fabric 5 on the offset side, and assists the auger structure 32 to stretch the piled fabric 5 to the opposite side, thus completing the automatic correction. S6. The drive device 33 periodically controls the auger structure 32 to reverse, so that the auger plates 321 on both sides gather the fabric 5 towards the middle, and rubs and washes the fabric 5 through the relative movement of the auger plates 321 and the fabric 5. S7. After washing, fabric 5 enters the next process under the traction of the fabric lifting wheel.

The drive device (33) periodically controls the auger structure (32) to reverse, so that the auger plates (321) on both sides gather the fabric (5) towards the center, and rubs and washes the fabric (5) through the relative movement of the auger plates (321) and the fabric (5). S7. After washing, the fabric (5) is pulled into the next process by the fabric lifting wheel.
