[0032] Combined with Figure 1 -Attached Fig. 9 , and also includes a sealing mechanism 2 for sealing the discharge hole 101, ensuring that external humid air does not enter the interior of the nozzle 1 through the discharge hole 101, ensuring the drying of the material, and ensuring the effective combination of the material and the ultrafine fiber; the sealing mechanism 2 includes a sealing head 201, the sealing head 201 has a conical structure, and the conical end of the sealing head 201 faces the interior of the feed pipe. The sealing head 201 is initially arranged inside the feed pipe and fits with the inner wall thereof. By setting the sealing head 201, the right end of the nozzle 1 can be sealed in the initial state, and the nozzle 1 can be double-sealed; in the feeding When the source transports material to the interior of the nozzle 1, it pushes the sealing head 201 to move toward the interior of the nozzle 1, opening the feed pipe so that the material can enter the interior of the nozzle 1 and be ejected through the discharge hole 101; it is worth noting that by setting one end of the sealing head 201 to a conical structure and facing the direction of the feed pipe, the material can be separated when entering the interior of the nozzle 1, so that the material can enter the interior of the discharge hole 101 in a divergent state, ensuring that the material can better combine with the ultrafine fibers; and the sealing head 201 can also prevent the material from entering the interior of the feed pipe in reverse.
[0033] The left end of the sealing head 201 is fixedly installed with a sleeve 202, which is fixedly connected to the inner wall of the nozzle 1 through a positioning ring, and the sleeve 202 and the positioning ring are slidably matched; the sleeve 202 moves synchronously with the sealing head 201; the inner sliding of the sleeve 202 is matched with a hollow rod 203, and by setting the hollow rod 203, on the one hand, the sleeve 202 can be supported, and on the other hand, it can rotate to control the opening and closing of the discharge hole 101; the right end of the hollow rod 203 is fixedly installed with an elastic bag 2031, and the elastic bag 2031 is fixedly installed with the inner wall of the nozzle 1 through a positioning ring, and the sleeve 202 is slidably matched with the positioning ring; the sleeve 202 moves synchronously with the sealing head 201; the inner sliding of the sleeve 202 is matched with a hollow rod 203, and the hollow rod 203 can support the sleeve 202 on the one hand, and can rotate on the other hand to control the opening and closing of the discharge hole 101; the right end of the hollow rod 203 is fixedly installed with an elastic bag 2031, and the elastic bag 2031 is fixedly installed with the inner wall of the nozzle 1 through a positioning ring; the sleeve 202 moves synchronously with the sealing head 201; the inner sliding of the sleeve 202 is matched with a hollow rod 203, and the hollow rod 203 can support the sleeve 202 on the one hand, and can rotate on the other hand to control the opening and closing of the discharge hole 101; the right end of the hollow rod 203 is fixedly installed with an elastic bag 2031, and the elastic bag 2031 is fixedly installed with the inner wall of the nozzle 1 The left end of the capsule 2031 is rotatably connected to the inner wall of the sleeve 202 through a bearing, and the elastic capsule 2031 is connected to the hollow rod 203 through two groups of symmetrically arranged connecting tubes 2032. By setting the elastic capsule 2031, when the sleeve 202 moves toward the inside of the nozzle 1, the elastic capsule 2031 will be stretched to start absorbing the gas inside the hollow rod 203. It is worth noting that the inner wall of the sleeve 202 is rotatably connected with a return spring (not shown in the figure), and the other end of the return spring is fixedly connected to the left end of the elastic capsule 2031.
[0034] Among them, a slide groove 204 is opened on the surface of the hollow rod 203, and the slide groove 204 is composed of a group of straight grooves and a group of curved grooves. The slide groove 204 is slidably connected with a slide rod 205 inside, and the slide rod 205 is fixedly installed on the inner wall of the sleeve 202. By setting the slide rod 205, when the sleeve 202 moves laterally, it can move synchronously inside the slide groove 204 and drive the hollow rod 203 to rotate; it is worth mentioning that the slide rod 205 will first slide inside the straight groove of the slide groove 204, and will start to pull the elastic bag 2031 during the sliding process, and start to absorb the gas inside the hollow rod 203, and when the slide rod 205 moves from the straight groove to the curved groove, it will continue to stretch the elastic bag 2031 and start to drive the hollow rod 203 to rotate, thereby driving the elastic bag 2031 and the compressed return spring to start rotating.
[0035] The left end of the hollow rod 203 penetrates through the interior of the nozzle 1 and is fixedly connected with a sealing plate 206. The number of the sealing plates 206 is the same as the number of the discharge holes 101 and is arranged one by one. An airbag 2061 is fixedly installed inside the right side of the sealing plate 206, and the airbag 2061 is connected to the hollow rod 203. By arranging the sealing plate 206 and the airbag 2061, the discharge hole 101 can be sealed to prevent humid air from entering the interior of the nozzle 1 and causing condensation of the material. It is worth noting that the airbag 2061 is in an expanded state in the initial state. When the inflated airbag 2061 contacts the discharge hole 101, part of it will enter the inside of the discharge hole 101, thereby sealing the discharge hole 101. It is worth noting that when the sleeve 202 drives the slide rod 205 to move inside the straight groove, the gas inside the airbag 2061 will be absorbed, so that the airbag 2061 returns to its initial state and moves out from the inside of the discharge hole 101. Then, when the slide rod 205 enters the curved groove, the hollow rod 203 will drive the sealing plate 206 and the airbag 2061 to rotate synchronously, thereby opening the discharge hole 101 and facilitating the discharge of materials.
[0036] Among them, a circular ring 207 is fixedly installed on the surface of the sealing plate 206, and the circular ring 207 is rotatably connected to the left end of the nozzle 1. By setting the circular ring 207, the stability of the hollow rod 203 and the sealing plate 206 can be guaranteed; a plurality of groups of mounting grooves 208 are equidistantly arranged inside the circular ring 207, and the mounting grooves 208 are T-shaped in a flat state, and the lower end of the mounting grooves 208 is connected to the outside. By setting the mounting grooves 208, the installation of components is facilitated and a limiting function can be played at the same time.
[0037] Combined with Figure 1 -Attached Fig. 9, and also includes a plurality of collision mechanisms 3 equidistantly arranged to vibrate the left end of the nozzle 1, thereby being able to collide with the surface of the discharge hole 101, so that the surface of the discharge hole 101 vibrates. On the one hand, when the equipment starts working, the dust on the surface of the discharge hole 101 can be shaken off, and on the other hand, after the equipment is finished working, the residual material inside the discharge hole 101 can be shaken off to avoid accumulation; the collision mechanism 3 includes an extrusion rod 301 arranged inside the mounting groove 208, one end of the extrusion rod 301 is arranged inside the arc groove 102, One end of the extrusion rod 301 is extruded and matched with the protrusion 103, and the other end of the extrusion rod 301 is elastically connected to the inner wall of the installation groove 208 through a connecting spring. By setting the extrusion rod 301, when the ring 207 rotates synchronously with the sealing plate 206, the extrusion rod 301 will be driven to slide inside the arc groove 102 and begin to be extruded and matched with the protrusion 103, so that the extrusion rod 301 moves toward the inside of the installation groove 208 and compresses the connecting spring; it is worth noting that the elastic coefficient of the compression spring is smaller than the elastic coefficient of the return spring.
[0038] The surface of the extrusion rod 301 is provided with a through slot 302, and the inner wall of the through slot 302 is movably connected with a telescopic block 303, the lower end of the telescopic block 303 is fixedly installed with a vertical rod 304, and the lower end of the vertical rod 304 extends out of the interior of the mounting slot 208, and the vertical rod 304 is movably installed on the inner wall of the mounting slot 208. By arranging the telescopic block 303 and the vertical rod 304, when the extrusion rod 301 moves toward the interior of the through slot 302, the vertical rod 304 can be driven to deflect and pull The telescopic block 303 is extended and retracted; a spherical collision block 305 is fixedly installed at the lower end of the vertical rod 304. By setting the spherical collision block 305, when the extrusion rod 301 drives the vertical rod 304 to deflect, the spherical collision block 305 can be driven to move synchronously, so that the spherical collision block 305 collides with one side of the discharge hole 101 to generate vibration, thereby achieving the purpose of shaking off dust and residual materials, ensuring that the material can be sprayed out normally, and combined with the ultrafine fibers, so that the performance of the non-woven fabric material meets the requirements.
[0039] Specifically, when the material supply source starts to convey the material to the inside of the nozzle 1, the pressure generated will drive the sealing head 201 in the feeding pipe to push the sleeve 202 to the inside of the nozzle 1, and start to compress the return spring, and the moving sleeve 202 starts to drive the slide bar 205 to slide inside the slide groove 204 and starts to stretch the elastic bag 2031, so that the elastic bag 2031 starts to absorb the gas inside the air bag 2061 connected to the hollow rod 203, so that the air bag 2061 returns to its original state, and when the slide bar 205 starts to move from the straight groove to the curved groove, with the continuous movement of the sealing head 201 and the sleeve 202, the hollow rod 203 will start to rotate, and drive the sealing plate 206 and the ring 207 to rotate synchronously, so that the discharge hole 101 is opened, so as to facilitate the ejection of the material and combine with the ultrafine fiber;
[0040] When the ring 207 rotates, it drives the extrusion rod 301 to slide inside the arc groove 102 and contact and squeeze the protrusion 103, so that the extrusion rod 301 moves toward the inside of the installation groove 208 and compresses the connecting spring. The moving extrusion rod 301 starts to drive the vertical rod 304 to deflect through the telescopic block 303, so that the spherical collision block 305 hits the surface of the discharge hole 101, and the dust on the surface of the discharge hole 101 is shaken off; when the extrusion rod 301 moves from one side of the protrusion 103 to the other side, the extrusion rod 301 starts to reset under the reaction force generated by the connecting spring, so that the vertical rod 304 and the spherical collision block 305 are reset synchronously, so as to facilitate the subsequent movement to collide with the discharge hole 101;
[0041] After production is completed, when the feed source stops feeding, the pressure disappears, and the compressed return spring begins to drive the sealing head 201 and the sleeve 202 to return to their original positions, so that the slide bar 205 begins to move from the curved groove to the inside of the straight groove and finally returns to its original position. During the resetting process of the slide bar 205, the sealing plate 206 and the ring 207 will be driven to reset through the hollow rod 203 first, so that the spherical collision block 305 will be squeezed and matched with the protrusion 103 again, and the residual material inside the discharge hole 101 will be cleaned to avoid accumulation. When the slide bar 205 moves to the inside of the straight groove, it will begin to compress the excess gas inside the elastic bag 2031, so that the gas enters the inside of the airbag 2061 through the hollow rod 203, causing the airbag 2061 to expand, thereby achieving the sealing of the discharge hole 101.
