Description

Technical Field

[0001] This invention relates to the field of textile manufacturing technology, and more specifically to an airflow web forming and leveling device. Background Technology

[0002] Airflow spinning uses airflow to transport fibers and form a uniform fiber web with randomly arranged fibers. Because the fibers in the web are distributed in three dimensions, the product exhibits advantages such as small differences in longitudinal and transverse strength and isotropy, thus gaining wide application. Airflow spinning requires a pre-treatment process to loosen the compressed, entangled fiber raw materials and remove impurities. Since various fiber raw materials used in spinning, such as raw cotton, wool, chemical staple fibers, cotton, linen, polyester, and scrap fabric, are mostly transported to textile mills in bales, opening the fibers is necessary before airflow spinning to produce high-quality yarn. The opened fibers are then transported to the web forming machine by a fan. A more uniform fiber web entering the web forming machine plays a crucial role in forming a uniform fiber web, and more uniform feeding during opening also ensures uniform feeding by the fan to the web forming machine during output. Therefore, the uniformity of feeding during opening affects the formation of the fiber web.

[0003] Chinese patent application CN102373516A discloses an airflow web forming machine that can reduce the output resistance of the cotton web, thereby improving the web forming speed and preventing the blockage of nonwoven fiber cotton in the cotton outlet channel. However, it has other drawbacks: in the current airflow web forming technology, the feeding work before the fiber opening is mostly done manually, resulting in poor uniformity. Consequently, after opening, the fiber is transported to the web forming machine in an uneven state, reducing the quality of the fiber web. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention proposes an airflow network uniformization device to solve the technical problems mentioned in the background art.

[0005] The technical solution adopted in this invention is an airflow network uniformization device, comprising: Conveyor belts are used to transport fiber raw materials into processing equipment. A storage cylinder, located in the middle of the rear side of the conveyor belt, is used to store fiber raw materials. A feeding component is provided at the bottom of the storage cylinder. The material spreading mechanism includes an electric track and a material spreading cylinder. The electric track is installed in the middle of the conveyor belt and extends to the rear end below the storage cylinder. The material spreading cylinder is slidably installed on the electric track for discharging raw fiber materials onto the conveyor belt. When the material spreading cylinder moves to the bottom of the storage cylinder, the feeding component opens to allow the raw fiber materials to fall into the material spreading cylinder.

[0006] In a preferred embodiment, the feeding assembly includes a first rotating shaft, a baffle, a circular rod, and a sliding plate. The bottom of the storage cylinder has a feeding port. The first rotating shaft is rotatably mounted at one end of the feeding port. The baffle is connected to the first rotating shaft and is used to block the feeding port. The first rotating shaft has a circular groove. The circular rod is slidably mounted in the circular groove. The side wall of the circular groove has a spiral groove. The circular rod is equipped with a guide block that matches the spiral groove. One end of the circular rod extends out of the circular groove and is connected to the sliding plate. An elastic element is provided between the sliding plate and the storage cylinder. The material spreading cylinder has an opening at its upper end, and a top block that matches the position of the sliding plate is fixed at the rear end of the material spreading cylinder.

[0007] In a preferred embodiment, a storage box is installed at the upper end of the storage cylinder, and a discharge channel is provided between the storage box and the storage cylinder. Several first discharge baffles are rotatably installed in the discharge channel via a second rotating shaft.

[0008] In a preferred embodiment, the front and rear sidewalls of the feeding channel are arc-shaped, and the first feeding partition is in contact with the sidewall of the feeding channel.

[0009] In a preferred embodiment, the storage cylinder is equipped with a fixing plate, and a horizontally arranged take-up shaft is rotatably mounted on the fixing plate. The take-up shaft is wound with a pull wire, the end of which is connected to the spreading cylinder. A coil spring is provided on one side of the fixing plate, and the take-up shaft is connected to the coil spring. The take-up shaft is connected to the second rotating shaft through a transmission wheel.

[0010] In a preferred embodiment, a vibrating plate is slidably installed in the middle of the storage cylinder, and an elastic reset member is provided between the lower side of the vibrating plate and the side wall of the storage cylinder. The vibrating plate has several strip-shaped fiber through grooves. The left end of the vibrating plate is connected to a push plate, and the left end of the second rotating shaft is connected to a first cam that abuts against the push plate.

[0011] In a preferred embodiment, the shaking plate is inclined with the left side higher than the right side, and the right end of the storage cylinder is provided with a collection box corresponding to the right end position of the shaking plate. The right wall of the storage cylinder is provided with a through groove communicating with the collection box.

[0012] In a preferred embodiment, a circular shell is provided at the bottom of the material spreading cylinder, and a material spreading opening is provided at the bottom of the circular shell. Several second material discharging partitions are rotatably installed at the center of the circular shell via a third rotating shaft. A gear is connected to the right end of the third rotating shaft, and a rack that meshes with the gear is installed at the lower end of the electric track.

[0013] In a preferred embodiment, the third rotating shaft is provided with an air passage, and the gear passes through its right end. The side wall of the third rotating shaft is provided with several evenly distributed air outlets. An elastic airbag is installed on the right wall of the circular shell. The elastic airbag is provided with a one-way air outlet and a one-way air inlet. The one-way air outlet is connected to an air pipe. The end of the air pipe extends into the right end of the air passage. A second cam that abuts against the elastic airbag is also installed on the right end of the third rotating shaft. An arc-shaped baffle located in the air passage is installed on the left inner wall of the circular shell. The arc-shaped baffle contacts the inner wall of the air passage, and the opening of the arc-shaped baffle faces downward.

[0014] As can be seen from the above technical solution, the beneficial technical effects of the present invention are as follows: 1. This invention allows the fiber raw material to be evenly distributed onto the conveyor belt by sliding the spreading cylinder back and forth on the electric track, ensuring uniformity of the raw material after opening, providing favorable conditions for subsequent airflow web formation, improving web formation quality, and the feeding component can automatically open after the spreading cylinder moves to the bottom of the storage cylinder each time, feeding the fiber raw material into the spreading cylinder, eliminating the need for frequent manual addition of fiber raw material into the spreading cylinder.

[0015] 2. During the back-and-forth sliding process of the material spreading cylinder, the first cam can be rotated by the pull line, which in turn drives the shaking plate to shake up and down repeatedly, dispersing the fiber raw material and improving the fiber dispersion. At the same time, the tilting setting of the shaking plate and the effect of gravity are used to make the clumped fibers enter the collection box and avoid blockage.

[0016] 3. During the back-and-forth sliding process of the material spreading cylinder of the present invention, the second cam is driven to rotate and squeeze the elastic air bag to generate airflow. The airflow is blown out from the lower air outlet by the arc-shaped baffle. The downward airflow can drive the fiber to move downward, making the feeding smoother and preventing the fiber from adhering to the second feeding partition. Attached Figure Description

[0020] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0021] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0022] like Figure 1-9 As shown, this embodiment provides an airflow network smoothing device, including the following components: Conveyor belt 1: Horizontally set up, used to transport fiber raw materials into the processing device, and is the basic component for fiber raw material transmission.

[0023] Storage cylinder 11: Located in the middle of the rear side of conveyor belt 1, it is used to store fiber raw materials. A feeding component is provided at its bottom. The specific structure is as follows: The feeding assembly includes a first rotating shaft 12, a baffle 13, a circular rod 14, and a sliding plate 15. The bottom of the storage cylinder 11 has a feeding port. The first rotating shaft 12 is rotatably mounted at one end of the feeding port. The baffle 13 is connected to the first rotating shaft 12 and is used to block the feeding port. The first rotating shaft 12 has a circular groove 16. The circular rod 14 is slidably mounted in the circular groove 16. The side wall of the circular groove 16 has a spiral groove 17. The circular rod 14 is equipped with a guide block that matches the spiral groove 17. One end of the circular rod 14 extends out of the circular groove 16 and is connected to the sliding plate 15. An elastic element 18 is provided between the sliding plate 15 and the storage cylinder 11. The elastic element 18 can be a spring, which provides a restoring force for the sliding plate 15.

[0024] The feeding assembly can be in two sets, namely, two sets of baffles 13 symmetrically arranged on the left and right are installed at the feeding port, and the sliding plate 15 slides back and forth with the storage cylinder 11, so that the circular rod 14 can only slide back and forth.

[0025] The material spreading mechanism includes an electric track 2 and a material spreading cylinder 21. The electric track 2 is arranged along the middle of the conveyor belt 1 and extends to the rear end below the storage cylinder 11. The material spreading cylinder 21 is slidably installed on the electric track 2 and is used to discharge raw fiber materials to the conveyor belt 1. The upper end of the material spreading cylinder 21 is open, and the rear end of the material spreading cylinder 21 is fixed with a top block 211 that matches the position of the sliding plate 15. When the material spreading cylinder 21 moves to the lower end of the storage cylinder 11, the top block 211 pushes the sliding plate 15 to move, causing the circular rod 14 to slide in the circular groove 16 and slide in the spiral groove 17 through the guide block, causing the first rotating shaft 12 to rotate, that is, the baffle 13 flips downward, opening the discharge port, and the fiber raw material falls into the material spreading cylinder 21 through the discharge port.

[0026] The length of the opening of the spreading cylinder 21 is greater than the length of the discharge port, which ensures that the top block 211 of the spreading cylinder 21 can completely catch the fiber raw material when it moves backward and comes into contact with the sliding plate 15, thus preventing the fiber raw material from scattering on the ground.

[0027] Storage bin 111: A storage bin 111 is installed on the upper end of the storage cylinder 11. A discharge channel 112 is provided between the storage bin 111 and the storage cylinder 11. Several first discharge partitions 114 are rotatably installed in the discharge channel 112 through a second rotating shaft 113. The front and rear side walls of the discharge channel 112 are arc-shaped, and the first discharge partitions 114 are in contact with the side walls of the discharge channel 112.

[0028] The fiber raw material in the storage bin 111 is blocked by several first feeding baffles 114 and cannot fall directly into the storage cylinder 11. When the spreading cylinder 21 slides back and forth along the electric track 2, it can drive several first feeding baffles 114 to rotate through the second rotating shaft 113, and convey the fiber raw material downward, so that the fiber raw material enters the storage cylinder 11 in a quantitative manner, realizing the automatic and quantitative addition of fiber raw material to the storage cylinder 11. After the spreading cylinder 21 moves back and forth once, when the feeding component at the bottom of the storage cylinder 11 opens to feed, a quantitative amount of fiber raw material falls into the spreading cylinder 21, and the fiber raw material spread on the conveyor belt 1 is more uniform.

[0029] Rewinding assembly: A fixing plate 3 is installed on the storage cylinder 11. A horizontally arranged winding shaft 31 is rotatably mounted on the fixing plate 3. A pull wire 311 is wound on the winding shaft 31, and the end of the pull wire 311 is connected to the spreading cylinder 21. A coil spring 32 is provided on one side of the fixing plate 3. The winding shaft 31 is connected to the coil spring 32. The winding shaft 31 is connected to the second rotating shaft 113 through a transmission wheel 33.

[0030] When the spreading cylinder 21 slides forward along the electric track 2, it drives the take-up shaft 31 to rotate through the pull wire 311, and drives the second rotating shaft 113 to rotate through the transmission wheel 33, so that the fiber raw material enters the storage cylinder 11 in a metered manner without the need for additional power; when the spreading cylinder 21 slides backward, the return force of the coil spring 32 drives the take-up shaft 31 to rotate in the opposite direction to take up the pull wire 311.

[0031] If it is not necessary for the second rotating shaft 113 to rotate during the backward movement of the electric track 2, a one-way bearing can be installed between the take-up shaft 3 and the transmission wheel 33, so that the second rotating shaft 113 will not be driven to rotate during the reverse rotation of the take-up shaft 31.

[0032] Shaking plate 4: A shaking plate 4 is slidably installed in the middle of the storage cylinder 11. An elastic reset member 44 is provided between the lower side of the shaking plate 4 and the side wall of the storage cylinder 11. The shaking plate 4 has several strip-shaped fiber through grooves that can intercept clumps of fiber. A push plate 41 is connected to the left end of the shaking plate 4. A first cam 42 that abuts against the push plate 41 is connected to the left end of the second rotating shaft 113.

[0033] The elastic reset element 44 can be one of a spring or a spring sheet, connected to the bottom of the shaking plate 4, supporting the shaking plate 4 and providing a reset elastic force.

[0034] When the fiber raw material falls from the storage box 111 onto the shaking plate 4, the second rotating shaft 113 rotates, driving the first cam 42 to rotate, which can push the push plate 41 to move downward. Through the elastic reset member, the shaking plate 4 is driven to reset upward, causing the shaking plate 4 to shake up and down repeatedly, dispersing the fiber raw material, so that it falls downward through the strip fiber channel to the bottom of the storage cylinder 11, thereby improving the dispersion of the fiber.

[0035] Furthermore, the shaking plate 4 is tilted with the left side higher than the right side, with an tilt angle of 5-10 degrees. During the up-and-down shaking process, the shaking plate 4 uses gravity to make the intercepted clumped fibers move to the right. The right end of the storage cylinder 11 is provided with a collection box 43 corresponding to the right end position of the shaking plate 4. The right wall of the storage cylinder 11 has a through groove that communicates with the collection box 43. The clumped fibers fall into the collection box 43 at the right end, avoiding blockage of the shaking plate 4.

[0036] Bottom assembly of the material spreading cylinder: A circular shell 5 is provided at the bottom of the material spreading cylinder 21. A material spreading port 51 is provided at the bottom of the circular shell 5. Several second feeding partitions 53 are rotatably installed at the center of the circular shell 5 via a third rotating shaft 52. A gear 54 is connected to the right end of the third rotating shaft 52. A rack 55 that meshes with the gear 54 is installed at the lower end of the electric track 2. The length of the rack 55 matches the width of the conveyor belt 1.

[0037] When the spreading cylinder 21 slides back and forth along the electric track 2, the meshing of the gear 54 and the rack 55 drives the third rotating shaft 52 to rotate. This causes several second feeding partitions 53 to rotate at a uniform speed, pushing the fiber raw material downwards onto the conveyor belt 1, so that the fiber raw material is evenly distributed on the conveyor belt 1. The conveyor belt then feeds the raw material evenly into the opening equipment, ensuring that the opened raw material is more uniform, thereby providing favorable conditions for subsequent airflow web formation and improving the quality of the web.

[0038] When the spreading cylinder 21 moves to the bottom of the storage cylinder 11, the gear 54 and the rack 55 disengage, and the second feeding partition 53 will not rotate, thus preventing fibers from falling outside the conveyor belt 1.

[0039] Airflow assist component: The third rotating shaft 52 is provided with an air passage 56, and a gear 54 passes through its right end. The side wall of the third rotating shaft 52 is provided with several evenly distributed air outlets. An elastic airbag 57 is installed on the right wall of the circular shell 5. The elastic airbag 57 is provided with a one-way air outlet and a one-way air inlet. The one-way air outlet is connected to an air pipe 58, and the end of the air pipe 58 extends into the right end of the air passage 56. A second cam 59 is also installed on the right end of the third rotating shaft 52, which abuts against the elastic airbag 57. An arc-shaped baffle 561 located in the air passage 56 is installed on the left inner wall of the circular shell 5. The arc-shaped baffle 561 contacts the inner wall of the air passage 56, and the opening of the arc-shaped baffle 561 faces downward.

[0040] When the third rotating shaft 52 rotates, it will drive the second cam 59 to rotate. The protruding part of the second cam 59 can squeeze the elastic airbag 57. The air inside the elastic airbag 57 enters the air pipe 58 through the one-way air outlet, and then is blown out from the several air outlets provided in the air passage 56. After the protruding part of the second cam 59 leaves the elastic airbag 57, the elasticity of the elastic airbag 57 can be restored, and the outside air is drawn into its interior through the one-way air inlet. The arc-shaped baffle 561 can block the several air outlets located on the upper side, so that the air can only be blown out from the several air outlets located on the lower side. The airflow blows downward and finally exits through the material laying port 51 at the bottom of the circular shell 5. The downward airflow can drive the fiber to move downward, making the material feeding smoother, and can prevent the fiber from adhering to the second feeding partition 53.

[0041] The working principle of the embodiments is explained in detail below: Quantitative addition of fiber raw materials; The storage bin 111 contains fiber raw materials, which are blocked by several first discharge baffles 114 and cannot fall directly into the storage cylinder 11.

[0042] When the spreading cylinder 21 slides forward along the electric track 2, it drives the take-up shaft 31 to rotate via the pull cable 311. Since the take-up shaft 31 is connected to the second rotating shaft 113 via the transmission wheel 33, the rotation of the take-up shaft 31 will drive the second rotating shaft 113 to rotate. The rotation of the second rotating shaft 113 will drive several first feeding partitions 114 to rotate, so that the fiber raw material enters the storage cylinder 11 in a quantitative manner, realizing the automatic and quantitative addition of fiber raw material to the storage cylinder 11.

[0043] When the material spreading cylinder 21 slides backward, the restoring force of the coil spring 32 drives the winding shaft 31 to rotate in the opposite direction to wind up the pull wire 311.

[0044] Shaking and loosening treatment of fiber raw materials; When the second rotating shaft 113 rotates, it will drive the first cam 42 connected to its left end to rotate. The rotation of the first cam 42 pushes the push plate 41 to move downward. The push plate 41 drives the shaking plate 4 to move downward. Then, through the elastic reset member, it drives the shaking plate 4 to reset upward, so that the shaking plate 4 shakes up and down.

[0045] The several strip-shaped fiber channels on the shaking plate 4 can intercept the clumped fibers and shake the fiber raw materials up and down to make them fall down to the bottom of the storage cylinder 11 through the strip-shaped fiber channels, thereby improving the dispersion of the fibers.

[0046] Furthermore, the shaking plate 4 is tilted with the left side higher than the right side, with an inclination angle of 5-10 degrees. During the up-and-down shaking process, gravity is used to make the intercepted clumped fibers move to the right and fall into the collection box 43 set at the right end through the through groove opened on the right wall of the storage cylinder 11, thus avoiding blockage of the shaking plate 4.

[0047] Control of fiber raw material feeding; When the spreading cylinder 21 moves to below the storage cylinder 11, the top block 211 fixed at the rear end of the spreading cylinder 21 pushes the sliding plate 15 to move. The movement of the sliding plate 15 causes the circular rod 14 to slide in the circular groove 16, and the guide block on the circular rod 14 slides in the spiral groove 17, thereby driving the first rotating shaft 12 to rotate. This causes the baffle 13 connected to the first rotating shaft 12 to flip downwards, opening the discharge port. The fiber raw material falls into the spreading cylinder 21 through the discharge port, thus realizing the addition of fiber raw material to the spreading cylinder 21 itself.

[0048] Uniform spreading of fiber raw materials; When the material spreading cylinder 21 slides back and forth along the electric track 2, several second feeding partitions 53, which are rotatably installed at the center of the circular shell 5 via the third rotating shaft 52, drive the third rotating shaft 52 to rotate through the meshing of the gear 54 with the rack 55 installed at the lower end of the electric track 2, so that the several second feeding partitions 53 rotate at a uniform speed and push the fiber raw material downward onto the conveyor belt 1.

[0049] When the third rotating shaft 52 rotates, it drives the second cam 59 to rotate, continuously squeezing the elastic airbag 57, causing air to be blown out from several air outlets provided in the air passage 56. The arc-shaped baffle 561 blocks several air outlets located on the upper side, so that air can only be blown out from several air outlets located on the lower side. The airflow blows downward and finally exits through the material feeding port 51 at the bottom of the circular shell 5. The airflow drives the fibers to move downward, making the feeding smoother and preventing the fibers from adhering to the second feeding partition 53.

[0050] The transport of fiber raw materials; The conveyor belt 1 is set horizontally to transport the fiber raw materials, which have been treated as described above and are evenly laid on it, into the processing device, so as to provide uniform raw materials for the subsequent air-laid web forming process.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
