Description

Technical Field

[0001] The present invention relates to the technical field of non-woven fabric processing, and specifically to a non-woven fabric drying device and its control method. Background Art

[0002] Non-woven fabric is a new generation of environmentally friendly material, which has the characteristics of moisture-proof, breathable, flexible, light in weight, non-flammable, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, recyclable, etc. Generally, polypropylene pellets are used as raw materials and are produced by a continuous one-step method of high-temperature melting, spinning, laying, and hot pressing and coiling. During the production process of non-woven fabric, a tunnel drying device is generally required for drying.

[0003] During the production and processing of non-woven fabric, it is necessary to wind the non-woven fabric. However, before winding the non-woven fabric, it needs to be dried. Generally, the non-woven fabric is sent into a drying device for drying. A large amount of water vapor will be generated during the drying of the non-woven fabric. The water vapor may condense into water droplets and adhere to the inner top wall of the drying device housing. Moreover, during the drying process of the non-woven fabric, a small amount of short fibers or fluff attached to it may be blown away to form flying hairs. Due to the adsorption of water droplets, the flying hairs will adhere to the inner top wall of the drying device housing following the water droplets. When the water droplets on the inner top wall of the drying device housing drip onto the non-woven fabric, it will not only affect the drying efficiency of the non-woven fabric, but also may cause the flying hairs to reattach to the non-woven fabric, affecting the quality of the non-woven fabric. Summary of the Invention

[0004] The purpose of the present invention is to provide a non-woven fabric drying device and its control method, aiming to solve the problem that the water droplets formed by the water vapor generated during the drying of the non-woven fabric in the general drying device affect the drying and quality of the non-woven fabric.

[0005] To achieve the above purpose, the present invention adopts the following technical scheme: A non-woven fabric drying device includes a mounting frame, an upper housing and a side housing mounted on the mounting frame, and further includes an auxiliary mechanism installed inside the upper housing and reciprocating along its length direction; the number of the side housings is two, and a conveying mechanism for conveying the non-woven fabric is installed between the two side housings. A plurality of heating mechanisms for heating and drying the non-woven fabric conveyed by the conveying mechanism are installed inside the mounting frame, and collecting grooves are also installed on both sides inside the mounting frame; the auxiliary mechanism includes two water tanks fixedly connected on one side, and both ends of the two water tanks are connected to the two collecting grooves respectively. A wiper strip is fixedly installed at the top of the connection of the two water tanks. The wiper strip is in mutual fit with the inner top wall of the upper housing. As the auxiliary mechanism reciprocates, the wiper strip scrapes off the water droplets and flying hairs attached to the inner top wall of the upper housing and drains them into the inside of the water tank. The water droplets and flying hairs entering the inside of the water tank form a water flow and flow into the inside of the collecting groove.

[0006] The beneficial effects are as follows: By installing the reciprocating lead screw at both ends of the upper shell with the first bearings and arranging an auxiliary mechanism on the reciprocating lead screw, the auxiliary mechanism can be driven by the reciprocating lead screw to perform reciprocating motion inside the upper shell, so that the water droplets and flying hairs on the inner top wall of the upper shell and the bottom of the filter screen can be scraped off by the wiper strip of the auxiliary mechanism, and the scraped water droplets and flying hairs fall into the inside of the water tank and are finally led out through the collection tank, achieving the purpose of removing water droplets and flying hairs, thereby improving the drying efficiency and quality of the non-woven fabric.

[0007] A further technical solution of the present invention is that the auxiliary mechanism further includes a plurality of connecting plates fixedly installed at the bottoms of the two water tanks, and threaded sleeves are fixedly installed at the ends of the plurality of connecting plates.

[0008] A further technical solution of the present invention is that vertical rods are arranged at the bottoms of the connecting plates at both ends of the water tank, and clamping mechanisms for clamping the non-woven fabric are arranged at the bottoms of the two vertical rods. The clamping mechanism is used for fixing the non-woven fabric when drying the end of the non-woven fabric and conveying one end of the non-woven fabric from one end of the drying device to the other end.

[0009] The beneficial effects are as follows: By arranging vertical rods at the bottoms of the connecting plates at both ends of the water tank to install the clamping mechanism, not only can the user easily pass one end of the non-woven fabric from one end of the drying device to the other end, but also the user can easily fix the end of the non-woven fabric for drying, so as to facilitate the connection between the end of the non-woven fabric and the winding mechanism, achieving the purpose of easy use.

[0010] A further technical solution of the present invention is that the clamping mechanism includes a fixing plate installed at a position below the middle of the outer surface of the vertical rod and a movable plate sleeved on the lower end of the vertical rod. Oppositely polarized magnetic blocks are respectively arranged inside the fixing plate and the movable plate, and the non-woven fabric is passed through between the fixing plate and the movable plate.

[0011] A further technical solution of the present invention is that a limiting piece for limiting the movable plate is arranged at the lower end of the vertical rod, and a pull ring is arranged at the bottom of the movable plate.

[0012] A further technical solution of the present invention is that the wiper strip is made of a water-absorbing material. A connecting sleeve is fixedly installed at the bottom of the water tank, and the connecting sleeve is sleeved on the connecting plate to install the water tank. A second mounting plate is fixedly installed at a position above the middle inside each extension part, and a cylinder is installed inside the second mounting plate. The cylinders inside the extension parts at both ends of each water tank are connected by a connecting pipe. A connecting block is fixedly installed at the bottom of each cylinder, and a mounting seat is fixedly installed at the bottom of the two connecting blocks inside the two extension parts at the same end. A roller is rotatably installed inside the mounting seat.

[0013] A further technical solution of the present invention is that tracks are fixedly installed inside both of the two collecting grooves. The tracks are wavy, and the crest of one track corresponds to the trough of the other track. The roller moves on the track as the auxiliary mechanism moves on the reciprocating screw rod. When the roller moves to the crest position of the track, it squeezes the cylinder, and at the same time drives one end of the water tank to move upward, so as to squeeze out the water adsorbed by the wiper strip into the interior of the water tank. The water extruded from the wiper strip finally converges on the second mounting plate inside the extension part. The two water tanks are interconnected; first water suction pipes and second water suction pipes are respectively fixedly installed at positions close to both ends of the connecting pipe. A drain pipe is also fixedly installed at a position close to one end of the connecting pipe. A first one-way valve is installed at a position in the middle of the connecting pipe close to the drain pipe, and a second one-way valve is installed inside the drain pipe.

[0014] The beneficial effects are as follows: By setting the wiper strip to be made of a water-absorbing material, arranging tracks with corresponding crest and trough positions inside the two collecting grooves, arranging a cylinder inside the extension part, installing a mounting seat with a roller at the bottom of the cylinder, and arranging a connecting pipe between the two cylinders inside the same water tank, and arranging water suction pipes at both ends of the connecting pipe and a drain pipe at one end of the connecting pipe, not only can the water inside the wiper strip be squeezed out by the roller squeezing the cylinder when passing through the crest, but also the water inside the extension part can be discharged, achieving the purpose of preventing water droplets from splashing during wiping.

[0015] A further technical solution of the present invention is that the top of the upper shell is in a necked shape. A plurality of exhaust pipes for guiding a part of the water vapor inside the upper shell out are fixedly installed at the necked part at the top of the upper shell. A filter screen is fixedly installed at the air inlet at the bottom of the exhaust pipe. First bearings are installed at opposite positions at both ends of the upper shell. The inner rings of the two first bearings are fixedly installed with a reciprocating screw rod for installing the threaded sleeve. A first driving motor for driving the reciprocating screw rod is fixedly installed at one end outside the upper shell.

[0016] The beneficial effect is that by setting the filter screen, flying hairs can be filtered to prevent the flying hairs from entering the air along with the water vapor and polluting the environment.

[0017] A further technical solution of the present invention is that the conveying mechanism includes a plurality of connecting rods. Both ends of each connecting rod are rotatably connected to the two side shells through second bearings. A driving roller for conveying the non-woven fabric is fixedly installed on the outer surface of each connecting rod. A sprocket is fixedly installed on each connecting rod. The sprockets on the plurality of connecting rods are driven by a chain. A second driving motor is fixedly installed on the outer surface of one of the side shells.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1

[0045] Before the non-woven fabric is wound up, it needs to be dried. During the drying process of the non-woven fabric by the non-woven fabric drying equipment in the general technology, the water vapor generated by heating the non-woven fabric may condense into water droplets and adhere to the inner top wall of the drying equipment housing. At the same time, a small amount of short fibers or fluff attached to the non-woven fabric may be blown away after drying to form flying fluff, which is adsorbed by the water droplets. When the water droplets attached with flying fluff drop onto the non-woven fabric, it will affect the drying efficiency and quality of the non-woven fabric.

[0046] Based on the above problems, in this embodiment, Figures 1-4 As shown, a non-woven fabric drying equipment includes a mounting frame 1. A upper housing 2 is fixedly installed on the top of the mounting frame 1. Side housings 3 are installed on the top of both sides of the mounting frame 1. A conveying mechanism 31 for conveying the non-woven fabric is installed between the two side housings 3. A first mounting plate 11 is installed inside the mounting frame 1. A plurality of heating mechanisms 12 for heating the non-woven fabric to dry it are installed inside the first mounting plate 11. A plurality of exhaust pipes 21 are installed on the top of the upper housing 2. An auxiliary mechanism 4 that reciprocates along the length direction is installed inside the upper housing 2. The non-woven fabric to be dried enters the equipment and is conveyed along the length direction of the mounting frame 1 by the conveying mechanism 31. The heating mechanism 12 heats the non-woven fabric to evaporate the moisture inside to generate water vapor. Part of the water vapor is discharged through the exhaust pipes 21, and the other part of the water vapor liquefies to form water droplets and adheres to the inner top wall of the upper housing 2. At the same time, the short fibers or fluff attached to the non-woven fabric after drying are blown away to form flying fluff and adhere to the water droplets. The auxiliary mechanism 4 is used to clean and discharge the water droplets on the inner top wall of the upper housing 2 and the water droplets attached with flying fluff.

[0047] As Figure 5 and Figure 6As shown in the figure, the mounting bracket 1 is fixedly formed by connecting a plurality of vertical rods 101, a first cross bar 102 and a second cross bar 103. A support leg is fixedly installed at the bottom end of each vertical rod 101. In this embodiment, the vertical rods 101, the first cross bar 102 and the second cross bar 103 are all stainless steel square tubes. A plurality of first cross bars 102 and second cross bars 103 are respectively fixedly installed between adjacent vertical rods 101 and connect them. The first cross bar 102 is located above the second cross bar 103. The first mounting plate 11 is located at the bottom of the plurality of first cross bars 102. A plurality of mounting blocks 111 for mounting the heating mechanism 12 are fixedly installed at the bottom of the first mounting plate 11. The heating mechanism 12 is fixedly connected to the mounting blocks 111 through mounting bolts. In this embodiment, the heating mechanism 12 is an electric hot air blower. A collecting groove 13 is fixedly installed at the top of the relative inner sides of the vertical rods 101. A lead-out pipe 131 is fixedly installed at the bottom of the collecting groove 13. The upper slot opening of the collecting groove 13 is connected to the outlet of the auxiliary mechanism 4, so as to collect the water droplets and flying hairs cleaned by the auxiliary mechanism 4, and form a mixed liquid of water droplets and flying hairs to be led out through the lead-out pipe 131. The user can set a container to receive the mixed liquid led out by the lead-out pipe 131.

[0048] As Figure 7 shown, the top of the upper shell 2 is in a converging shape. The exhaust pipe 21 is fixedly installed at the converging part at the top of the upper shell 2. A filter screen 211 is fixedly installed at the air inlet at the bottom of the exhaust pipe 21. The filter screen 211 is used to block and filter the flying hairs to prevent the flying hairs from being led out through the exhaust pipe 21 and affecting the external environment. The auxiliary mechanism 4 can also clean the water droplets and flying hairs at the bottom of the filter screen 211.

[0049] First bearings 20 are installed at the relative positions at both ends of the upper shell 2. The inner rings of the two first bearings 20 are fixedly installed with a reciprocating lead screw 22 for installing the auxiliary mechanism 4. A first driving motor 23 for driving the reciprocating lead screw 22 is fixedly installed at one end outside the upper shell 2. The first driving motor 23 drives the reciprocating lead screw 22 to rotate, and then drives the auxiliary mechanism 4 on the reciprocating lead screw 22 to perform reciprocating cleaning inside the upper shell 2 along its length direction. The first driving motor 23 can be controlled by a controller to drive the auxiliary mechanism 4 to reciprocate once within five minutes to avoid waste of resources. It can be imagined that the movement interval of the auxiliary mechanism 4 can be adjusted according to the actual situation.

[0050] As Figure 8 and Figure 9As shown, multiple groups of second bearings 30 are fixedly installed on the relative inner sides of the two side shells 3. The number of second bearings 30 in each group is two. The two second bearings 30 in each group are oppositely installed on the two side shells 3. The conveying mechanism 31 includes multiple connecting rods 311. A driving roller 312 for conveying non-woven fabric is fixedly installed on the outer surface of each connecting rod 311. Both ends of each connecting rod 311 are fixedly connected to the two second bearings 30 in each group respectively. A sprocket 313 is fixedly installed on each connecting rod 311. The sprockets 313 on the multiple connecting rods 311 are driven by a chain 314. A second driving motor 32 is fixedly installed on the outer surface of one of the side shells 3. The rotating shaft of the second driving motor 32 is fixedly connected to one of the connecting rods 311, so as to drive the multiple driving rollers 312 simultaneously through the second driving motor 32.

[0051] As Figure 4 and Figure 10 As shown, the auxiliary mechanism 4 includes a threaded sleeve 41 installed on the reciprocating lead screw 22. Multiple connecting plates 42 for installing the water tank 43 are fixedly installed on the outer surface of the threaded sleeve 41. The number of water tanks 43 is two. One side of the two water tanks 43 is fixedly connected. Extension parts 431 are provided at both ends of the two water tanks 43. The lower end of the extension part 431 is connected to the upper end of the collection tank 13. A baffle 432 is fixedly installed on the outer side of the extension part 431. The baffle 432 is used to block the water flow flowing from the extension part 431 to the collection tank 13 to prevent water from splashing. A wiper strip 44 is fixedly installed at the top of the side wall on the connected side of the two water tanks 43. The wiper strip 44 is attached to the inner top wall of the upper shell 2. In this embodiment, the wiper strip 44 is made of rubber. The reciprocating lead screw 22 drives the threaded sleeve 41 to move reciprocally, so as to scrape off the water droplets and flying hairs on the inner top wall of the upper shell 2 and the bottom of the filter screen 211 through the wiper strip 44, making them fall into the interior of the water tank 43 to form a water flow, and finally being led out through the outlet pipe 131 at the bottom of the collection tank 13.

[0052] A control method for a non-woven fabric drying device includes the following steps:

[0053] S1: Thread one end of the non-woven fabric through the interior of the drying device;

[0054] S2: Start the conveying mechanism 31 and the heating mechanism 12 to dry the non-woven fabric, and set the auxiliary mechanism 4 to run one reciprocating cycle after five minutes;

[0055] S3: During the drying process of the non-woven fabric, detect the formation of water droplets on the inner top wall of the upper shell 2, adjust the running interval time of the auxiliary mechanism 4 according to the actual situation, and continue the drying work.

[0056] In this embodiment, by installing the reciprocating lead screw 22 through the first bearings 20 provided at both ends of the upper housing 2, and arranging the auxiliary mechanism 4 on the reciprocating lead screw 22, the auxiliary mechanism 4 can be driven by the reciprocating lead screw 22 to perform reciprocating motion inside the upper housing 2, so as to scrape off the water droplets and flying hairs on the inner top wall of the upper housing 2 and the bottom of the filter net 211 through the wiper strip 44 of the auxiliary mechanism 4, making the scraped water droplets and flying hairs fall into the interior of the water tank 43 and finally being led out through the collection tank 13, achieving the purpose of removing water droplets and flying hairs, thereby improving the drying efficiency and quality of the non-woven fabric.

[0057] Embodiment 2

[0058] During the actual use process, it is found that when the non-woven fabric is placed inside the drying device, due to the presence of the upper housing 2 and the side housing 3, it is not convenient for the user to thread the non-woven fabric from one end of the drying device to the other end. The end of the non-woven fabric needs to be wound around the winding mechanism after drying. However, the end of the non-woven fabric lacks the limitation of the winding mechanism during drying, and the non-woven fabric will flutter along with the heating mechanism 12. The user needs to additionally set up a fixing mechanism to fix it, which is not convenient for the drying work. Therefore, further improvements will be made on the basis of the above embodiment.

[0059] As Figure 11 and Figure 12 shown, the difference between this embodiment and Embodiment 1 is that vertical rods 45 are respectively arranged at the bottoms of two connecting plates 42 located at both ends of the water tank 43, and a clamping mechanism for clamping and fixing the non-woven fabric is arranged at the bottom of the vertical rods 45. The clamping mechanism includes a fixing plate 451 installed at a position below the middle of the outer surface of the vertical rod 45 and a movable plate 452 sleeved on the lower end of the vertical rod 45. Oppositely polarized magnetic blocks (not shown in the figure) are respectively arranged inside the fixing plate 451 and the movable plate 452, so that the movable plate 452 can be connected to the fixing plate 451. The non-woven fabric is threaded between the fixing plate 451 and the movable plate 452, so as to clamp the two corners at one end of the non-woven fabric through the two groups of fixing plates 451 and movable plates 452, thereby facilitating the user to move the non-woven fabric from one end of the drying device to the other end by moving the auxiliary mechanism 4, and the clamping and fixing of the non-woven fabric by the clamping mechanism also facilitates the user to dry the end of the non-woven fabric.

[0060] A limiting piece 453 for limiting the movable plate 452 is arranged at the lower end of the vertical rod 45 to prevent the movable plate 452 from separating from the fixing plate 451 and falling off the vertical rod 45. A pull ring 454 is arranged at the bottom of the movable plate 452, which can facilitate the user to separate the movable plate 452 from the fixing plate 451 for installing the non-woven fabric.

[0061] During use, first install the non-woven fabric between the two clamping mechanisms, start the first driving motor 23 to transport the auxiliary mechanism 4 to the other end of the drying device, then dry the part of the non-woven fabric inside the drying device, and finally loosen the clamping mechanism to install the end of the non-woven fabric on the winding mechanism and continue the subsequent drying.

[0062] In this embodiment, the clamping mechanism is installed by arranging vertical rods 45 at the bottom of the connecting plates 42 located at both ends of the water tank 43. This not only facilitates the user to thread one end of the non-woven fabric from one end of the drying device to the other end, but also enables the user to fix the end of the non-woven fabric for drying, thus facilitating the connection between the end of the non-woven fabric and the winding mechanism, achieving the purpose of convenient use.

[0063] Embodiment 3

[0064] It is also found in the actual use process that during the process of using the wiper strip 44 to wipe water, the water droplets wiped off may splash and wet the non-woven fabric, affecting the drying of the non-woven fabric.

[0065] As Figures 13-16 shown, the difference between this embodiment and Embodiment 1 is that the wiper strip 44 is made of a water-absorbing material. A connecting sleeve 433 is fixedly installed at the bottom of the water tank 43, and the connecting sleeve 433 is sleeved on the connecting plate 42 to install the water tank 43. A second mounting plate 434 is fixedly installed at a position above the middle inside each extension part 431. A cylinder 435 is installed inside the second mounting plate 434. The cylinders 435 inside the extension parts 431 at both ends of each water tank 43 are connected by a connecting pipe 436. A connecting block 437 is fixedly installed at the bottom of each cylinder 435. A mounting seat 438 is fixedly installed at the bottom of the two connecting blocks 437 inside the two extension parts 431 at the same end. A roller 439 is rotatably installed inside the mounting seat 438.

[0066] Tracks 14 are fixedly installed inside both collection tanks 13. The tracks 14 are wavy, and the crest of one track 14 corresponds to the trough of the other track 14. As the auxiliary mechanism 4 moves on the reciprocating lead screw 22, the roller 439 moves on the track 14. When the roller 439 moves to the crest position of the track 14, it squeezes the cylinder 435, and at the same time drives one end of the water tank 43 to move upward, thereby squeezing out the water adsorbed by the wiper strip 44 into the inside of the water tank 43. The water squeezed out from the wiper strip 44 finally gathers on the second mounting plate 434 inside the extension part 431, and the two water tanks 43 are interconnected.

[0067] At positions near both ends of the connecting pipe 436, a first water suction pipe 4361 and a second water suction pipe 4362 are fixedly installed respectively. At a position near one end of the connecting pipe 436, a drain pipe 4363 is also fixedly installed. A first one-way valve is installed at a position in the middle of the connecting pipe 436 near the drain pipe 4363, and a second one-way valve is installed inside the drain pipe 4363.

[0068] During use, as the auxiliary mechanism 4 moves on the reciprocating lead screw 22, when one end of the cylinder 435 is squeezed, the water inside the same-side extension part 431 is led out through the connecting pipe 436 via the first water suction pipe 4361 and the connecting pipe 436 to the inside of the extension part 431 at the other end. When the cylinder 435 at the other end is squeezed, due to the existence of the first one-way valve, the water inside the extension part 431 at the other end cannot be transported inside the connecting pipe 436, and the water inside the extension part 431 at the other end can only be led out through the drain pipe 4363.

[0069] In this embodiment, by setting the wiper strip 44 to be made of a water-absorbing material, arranging tracks 14 with corresponding wave crests and wave troughs inside the two collecting grooves 13, arranging a cylinder 435 inside the extension part 431, arranging a mounting seat 438 with a roller 439 installed at the bottom of the cylinder 435, and arranging a connecting pipe 436 between the two cylinders 435 inside the same water tank 43, arranging water suction pipes at both ends of the connecting pipe 436, and arranging a drain pipe at one end of the connecting pipe 436, not only can the water inside the wiper strip 44 be squeezed out by squeezing the cylinder 435 when the roller 439 passes over the wave crest, but also the water inside the extension part 431 can be discharged, achieving the purpose of preventing water droplets from splashing during wipering.

[0070] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
