Description

Technical Field

[0001] The present invention relates to the technical field of non-woven spunlace, and specifically relates to a non-woven spunlace machine with an anti-deviation function and a spunlace method thereof. Background Art

[0002] The non-woven spunlace machine is used for spray-spinning and spunlace treatment on both sides of the fiber web to reinforce and entangle the fiber web. For example, Chinese invention patent CN112680885A discloses a spunlace machine for non-woven fabrics, which is provided with a water circulation mechanism between the second side plate and the spraying box. The water circulation mechanism includes a water pump, a water inlet pipe and a water outlet pipe. The water pump is communicated with the inside of the spraying box through the water outlet pipe. The water inlet pipe is fixedly connected to the water pump. One end of the water inlet pipe far away from the water pump penetrates the bottom end of one group of second side plates, and a filter screen is embedded at the end of the water inlet pipe penetrating the second side plate. Among them, an electromagnetic valve is installed at the top end of the water inlet pipe. When processing, the sprayed water is filtered through the water circulation mechanism and then returned to the spraying box, avoiding waste of water resources and reducing processing costs.

[0003] However, the above structure still has the following problems: First, during the water circulation process, impurities are also likely to deposit in the space enclosed by the bottom plate, the first side plate and the second side plate under the action of their own gravity. At the same time, the filter screen will gradually be blocked, resulting in poor filtering effect and reduced water circulation efficiency. In addition, separate impurity cleaning work needs to be carried out regularly. Second, when the width of the non-woven fabric to be processed changes, it is difficult to change the width of the water outlet. In addition, the non-woven fabric will shift to a certain extent during the transmission process, affecting the spunlace effect of the non-woven fabric. Therefore, an anti-deviation mechanism needs to be designed.

[0004] Based on this, the present invention designs a non-woven spunlace machine with an anti-deviation function and a spunlace method thereof to solve the above problems. Summary of the Invention

[0020] A hydroentangling method for a non-woven fabric hydroentangling machine with an anti-deviation function includes the following steps:

[0021] 1. The non-woven fabric is horizontally transmitted through the third rotating roller and the first rotating roller, pressed and transmitted through the fourth rotating roller, and transmitted to the outside through the second rotating roller;

[0022] 2. Water is introduced through the water supply pipe, and the water in the inclined water tank is filtered by the straight filter plate. After passing through the straight filter plate, the water enters the adjustable hydroentangling assembly and then returns to the inclined water tank. When cleaning the impurities at the bottom of the inclined water tank, the first motor is started to drive the connecting shaft to rotate. The connecting shaft drives another connecting shaft to rotate through the synchronous belt assembly, and the synchronous belt assembly drives the scraper to rotate. When the scraper rotates to the lower part, it fits and slides with the arc part of the inclined water tank, scraping the impurities deposited at the bottom of the inclined water tank upward. At the same time, when the scraper moves upward, it scrapes the impurities accumulated on the straight filter plate. Then, the inclined scraper moves upward vertically to drive the impurities to the top. At this time, the bottom of the scraper is above the straight filter plate, and the impurities are successively scraped into the waste filter box. After being filtered by the waste filter box, it is only necessary to regularly remove the waste filter box to clean the impurities;

[0023] 3. When the water pump is started, the water enters the water inlet pipe through the inclined water tank, then enters the water outlet pipe through the water pump, then enters the connecting water tank, and finally sprays out through the hydroentangling needles. When adjusting the water outlet width, the second motor is started to drive the first bevel gear to rotate. The first bevel gear drives the second bevel gear to rotate. The second bevel gear drives the symmetric threaded rod to rotate. The symmetric threaded rod drives the two plugging plates to move towards each other or move in the opposite direction through the symmetric threads, realizing the change of the width of the water storage space formed by the two plugging plates and the connecting water tank, and the change of the number of hydroentangling needles between the two plugging plates, thereby changing the water outlet width;

[0024] 4. When the non-woven fabric is fed, the third motor drives the driving wheel to rotate. The driving wheel drives the driven wheel to rotate through the driving belt. The steering of the front and rear driving belts is opposite, so as to unfold the non-woven fabric outward. When the position sensor senses the position of the non-woven fabric and adjusts the positions of the two position sensors according to the width of the non-woven fabric, loosen the fixing part, move the sliding plate along the limit groove, and then tighten the fixing part. Both the third motor and the position sensor are connected to the external controller. When one side position sensor does not sense the non-woven fabric, it means that there is an offset. The external controller controls the third motor on that side to increase the rotation speed. When the position sensor senses the non-woven fabric again, the external controller controls the third motor on that side to restore the original uniform rotation speed.

[0025] Beneficial effects

[0026] The present invention filters, cleans, and recycles water through a filtering component. Specifically, water enters through a water inlet pipe, and the water in the inclined water tank is filtered by a direct filter plate. After passing through the direct filter plate, the water enters a regulating hydroentangling component and then returns to the inclined water tank, achieving recycling. When cleaning the impurities at the bottom of the inclined water tank, the first motor is started to drive the connecting shaft to rotate. The connecting shaft drives another connecting shaft to rotate through a synchronous belt component, and the synchronous belt component drives the scraper to rotate. When the scraper rotates to the lower part, it fits and slides with the arc part of the inclined water tank, scraping the impurities deposited at the bottom of the inclined water tank upward, preventing impurities from depositing at the lower end of the bottom of the inclined water tank. At the same time, when the scraper moves upward, it scrapes the impurities accumulated on the direct filter plate, preventing the filter holes of the direct filter plate from being blocked and ensuring the filtering effect of the direct filter plate. Then, the inclined scraper moves upward vertically to drive the impurities to the uppermost part. At this time, the bottom of the scraper is located above the direct filter plate, and the impurities are successively scraped into the waste filter box. After being filtered by the waste filter box, it is only necessary to regularly remove the waste filter box to clean the impurities, and then the synchronous belt component drives the scraper to rotate to the front side of the connecting shaft; the non-woven fabric is guided and supported by a guiding component, the water outlet width is adjusted according to the width of the non-woven fabric by a regulating hydroentangling component, the non-woven fabric is unfolded by a spreading and anti-deviation component, and automatic deviation correction is performed when the non-woven fabric deviates;

[0027] During the water circulation process of the present invention, the water can be filtered and the impurities can be cleaned through the filtering component, which is beneficial to ensuring the filtering effect and the water outlet circulation efficiency. It is only necessary to regularly remove the waste filter box to clean the impurities, and there is no need to regularly perform cumbersome, time-consuming, and laborious separate cleaning work on the inclined water tank; the water outlet width can be changed according to the width of the non-woven fabric to be processed, improving the scope of application; by designing an anti-deviation mechanism, the non-woven fabric is prevented from deviating during transmission, ensuring the hydroentangling effect of the non-woven fabric.

When the position sensor 52 senses the non-woven fabric again, the external controller controls the third motor 58 on that side to resume the original uniform rotation speed, and the anti-deviation purpose can be achieved.

[0064] In some embodiments, a water acupuncture method for a non-woven fabric water acupuncture machine with an anti-deviation function includes the following steps:

[0065] 1. The non-woven fabric is horizontally transported through the third rotating roller 33 and the first rotating roller 31, pressed and transported through the fourth rotating roller 34, and transported to the outside through the second rotating roller 32.

[0066] 2. Water is introduced through the water inlet pipe 24, and the water in the inclined water tank 22 is filtered by the straight filter plate 26. After passing through the straight filter plate 26, the water enters the adjustable hydroentangling assembly 4 and then returns to the inclined water tank 22. When cleaning the impurities at the bottom of the inclined water tank 22, the first motor 23 is started to drive the connecting shaft 27 to rotate. The connecting shaft 27 drives another connecting shaft 27 to rotate through the synchronous belt assembly 29, and the synchronous belt assembly 29 drives the scraper 28 to rotate. When the scraper 28 rotates to the lower part, it fits and slides with the arc part of the inclined water tank 22, scraping the impurities deposited at the bottom of the inclined water tank 22 upward. At the same time, when the scraper 28 moves upward, it scrapes the impurities accumulated on the straight filter plate 26. Then, through the upward vertical movement of the inclined scraper 28, the impurities are driven to the uppermost part. At this time, the bottom of the scraper 28 is located above the straight filter plate 26, and the impurities are successively scraped into the waste filter box 25. After being filtered by the waste filter box 25, it is only necessary to regularly remove the waste filter box 25 to clean the impurities.

[0067] 3. The water pump 44 is started, and the water enters the water inlet pipe 45 through the inclined water tank 22, then enters the water outlet pipe 42 through the water pump 44, then enters the connecting water tank 46, and finally is sprayed out through the hydroentangling needles 43. When it is necessary to adjust the water outlet width, the second motor 47 is started to drive the first bevel gear 410 to rotate. The first bevel gear 410 drives the second bevel gear 411 to rotate, and the second bevel gear 411 drives the symmetric threaded rod 48 to rotate. The symmetric threaded rod 48 drives the two sealing plates 49 to move towards each other or in the opposite direction through the symmetric threads, realizing the change of the width of the water storage space formed by the two sealing plates 49 and the connecting water tank 46, and the change of the number of hydroentangling needles 43 between the two sealing plates 49, thereby changing the water outlet width.

[0068] 4. When the non-woven fabric is fed, the third motor 58 drives the driving wheel 59 to rotate. The driving wheel 59 drives the driven wheel 510 to rotate through the driving belt 53. The steering directions of the front and rear two driving belts 53 are opposite, so as to expand the non-woven fabric outwards. When the position of the non-woven fabric is sensed by the position sensor 52 and the positions of the two position sensors 52 are adjusted according to the width of the non-woven fabric, loosen the fixing member 57, move the sliding plate 56 along the limiting groove 55, and then tighten the fixing member 57. Both the third motor 58 and the position sensor 52 are connected to an external controller. When one side position sensor 52 does not sense the non-woven fabric, it means that there is an offset. The external controller controls the third motor 58 on that side to increase the rotation speed. When the position sensor 52 senses the non-woven fabric again, the external controller controls the third motor 58 on that side to resume the original uniform rotation speed.
