Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production equipment technology, and in particular to an auxiliary heating device with an adjustable angle for a nonwoven fabric spinneret. Background Technology

[0002] The nonwoven spinneret is the core component in the nonwoven production line that converts polymer melt into fiber. It is essentially a metal plate with precise micropores on its surface. In the meltblown process, the polymer melt is easily affected by ambient temperature fluctuations during extrusion, resulting in uneven fiber cooling rates. Therefore, an auxiliary heating device is required to maintain the temperature stability of the spinneret and its surrounding area.

[0003] A search revealed Chinese Patent Publication No. CN218910608U, which discloses a spinneret for spunbond nonwoven fabric production. This patent relates to the field of spinneret structure technology. To address the problem that existing spinnerets may experience material cooling during spinning due to insufficient temperature at the spinneret end, potentially clogging the spinneret orifices and affecting its performance, the design includes a feed plate mounted below the spinneret body. A spinneret holder is located at one end of the spinneret body. A vent hole is provided inside the upper part of the spinneret body, and a fixing screw hole is provided on one side of the vent hole. The design also includes a... The spinneret has a temperature control channel and a material storage tank inside. One end of the material storage tank has a limit mounting groove, and the other end has a spinneret hole. Both ends of the material storage tank have mounting grooves, and a heating plate is installed inside the mounting grooves. A control device is installed on one side of the spinneret. However, in actual use, because the heating plate cannot adjust the heating position in real time according to the temperature changes during fiber forming, the fibers may stick together due to local overheating in the early stage, or break due to insufficient temperature in the later stage. This results in unqualified fiber production quality, which cannot meet the user's needs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an auxiliary heating device with an adjustable angle for the nonwoven fabric spinneret, which aims to improve the problem in the prior art that the heating position cannot be adjusted in real time according to temperature changes during the fiber forming process.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary heating device for an adjustable angle nonwoven spinneret, comprising a base plate, transmission mechanisms provided on both the left and right sides of the base plate, two transmission mechanisms for dynamically adjusting the angle and distance of the heating device simultaneously, clamping mechanisms provided at the bottom of both transmission mechanisms for clamping the heating device, and fixing mechanisms provided at the four corners of the bottom of the base plate for fixing the detachable perforated plate at the bottom of the base plate; The transmission mechanism includes two fixed blocks. The adjacent sides of the two fixed blocks are fixedly connected to the upper middle part of the left and right ends of the base plate, respectively. Rotating rods are rotatably connected to the inner sides of the two fixed blocks. Gears are fixedly connected to the middle of the outer walls of the two rotating rods. Rotating shells are provided on the opposite sides of the two fixed blocks. The front and rear ends of the two rotating rods penetrate the inner walls of the corresponding fixed blocks and are fixedly connected to the front and rear sides of the inner walls of the corresponding rotating shells, respectively. Sliding grooves are provided on the opposite sides of the interiors of the two rotating shells. Racks are slidably connected inside the two sliding grooves. The two racks are meshed with the corresponding gears, respectively. A drive assembly is provided on the rear side of the two rotating rods.

[0006] The above technical solution works by rotating the rod to drive the gear and the rotating shell to rotate synchronously. At the same time, the rotation of the gear drives the rack inside the rotating shell to move in a straight line. As the rotating shell rotates, the rack can rotate relative to the gear while moving, thereby driving the heating device connected to the bottom to move together, thus completing the synchronous adjustment of the angle and distance of the heating device.

[0007] As a further description of the above technical solution: The clamping mechanism includes two connecting shells. The tops of the two connecting shells are fixedly connected to the bottoms of corresponding racks. A lead screw is rotatably connected to the middle of the inner side of each of the two connecting shells. A wedge block is threadedly connected to the outer wall of each of the two lead screws. Dovetail tenons are fixedly connected to the front and rear sides of each of the two wedge blocks. Wedge push rods are slidably connected to the front and rear sides of the inner side of each of the two connecting shells. Dovetail grooves are opened on adjacent sides of multiple wedge push rods. One side of each of the multiple dovetail tenons engages with the corresponding dovetail groove. Side plates are fixedly connected to the front and rear ends of multiple wedge push rods. Lead screws are rotatably connected to the front and rear sides of the bottom of multiple wedge push rods. A slider is threadedly connected to the upper middle part of the outer wall of multiple lead screws.

[0008] The above technical solution works as follows: by rotating screw one, the wedge block moves and pushes the wedge push rod to both sides, thus freeing the heating device from fixation and allowing for quick replacement. Then, by rotating screw one in the opposite direction, the wedge block engages with the dovetail groove of the wedge push rod through the dovetail tenon, creating a pulling force on the wedge push rod and pulling the wedge push rods on both sides towards the center, thereby limiting the heating device to the slider. Then, by rotating screw two, the slider moves upward, further fixing the heating device.

[0009] As a further description of the above technical solution: The two drive components each include a housing. The adjacent sides of the two housings are respectively fixedly connected to the left and right rear ends of the base plate. The rear ends of the two rotating rods each pass through the corresponding rotating housing and one side of the housing and are fixedly connected to a worm gear. A transmission rod is provided between the adjacent two housings. The left and right ends of the transmission rod pass through the corresponding housing and are fixedly connected to a worm. The two worms are respectively meshed with the corresponding worm gears. A motor is fixedly connected to the upper right part of the right end of the right housing. The output end of the motor passes through the right side of the corresponding housing and is fixedly connected to the right end of the corresponding worm.

[0010] The above technical solution involves a motor driving the front worm to rotate, which in turn drives the rear worm to rotate via a transmission rod, enabling both sides to operate synchronously. When the worm rotates, it drives the worm wheel to rotate, which in turn drives the rotating rod to rotate, thus completing the drive of the transmission mechanism.

[0011] As a further description of the above technical solution: The fixing mechanism includes multiple connecting columns, which are fixedly connected to the four corners at the bottom of the base plate. A support plate is fixedly connected to one side of the outer wall of each of the multiple connecting columns, and a fixing plate is rotatably connected to the middle of the outer wall of each of the multiple connecting columns. A positioning hole is opened on one side of each of the multiple support plates and the fixing plate, and a bolt is threaded to the inner side of each of the multiple positioning holes.

[0012] The above technical solution allows for the limiting of the bottom perforated plate of the substrate by rotating the fixed plate. After aligning the positioning holes of the support plate and the fixed plate, the perforated plate can be fixed by screwing in bolts, preventing the connection between the substrate and the perforated plate from being unstable.

[0013] As a further description of the above technical solution: Each of the multiple side plates has a limiting groove on one side, and one end of each of the multiple sliders is slidably connected to the inner side of the corresponding limiting groove.

[0014] Through the above technical solution, the limiting groove can provide guidance and limit when the slider moves by the rotation of the lead screw, so that the slider will not follow the rotation of the lead screw, but can move up and down.

[0015] As a further description of the above technical solution: Both of the connecting shells have a heat-conducting shell at their bottom, and both heat-conducting shells have a heating wire fixedly connected inside. Both heat-conducting shells have a temperature sensor in the middle of an adjacent side.

[0016] The above technical solution involves using an electric heating wire to release heat, which is then evenly distributed by a heat-conducting shell to maintain a suitable temperature for the fiber. A temperature sensor monitors the temperature of the extruded fiber in real time.

[0017] As a further description of the above technical solution: The substrate has movable grooves on both the front and rear sides of its bottom, and the same scraper is slidably connected to the left side of the interior of the two movable grooves.

[0018] The above technical solution provides the installation position of the scraper and provides limiting and guiding when the scraper moves, so that the scraper can scrape off the residual polymer at the bottom of the spinneret.

[0019] As a further description of the above technical solution: The top of the substrate is connected to an injection tube, and the outer wall of the injection tube is threadedly connected to a threaded connecting cylinder.

[0020] The above technical solution allows the melt to enter the spinneret through the injection pipe, and the threaded connecting sleeve can quickly connect the injection pipe to the output pipe of the extruder.

[0021] This utility model has the following beneficial effects: 1. In this utility model, a motor drives a worm gear to rotate, which in turn drives a worm wheel to rotate, and the worm wheel drives a rotating rod to rotate. When the rotating rod rotates, the rotating shell and gears rotate accordingly. The rack moves linearly inside the rotating shell through the gears. At the same time, the rack is driven to rotate by the rotating shell, so that the angle and distance between the heating device at the bottom of the rack and the fiber are adjusted simultaneously. This ensures that the fiber maintains an appropriate temperature throughout the molding process, avoids uneven heat distribution that could lead to fiber breakage, and meets the needs of users.

[0022] 2. In this utility model, by rotating screw one, the wedge block pushes the wedge push rods on both sides to move, thereby enabling the replacement of the heat-conducting shell. The replaced heat-conducting shell is placed at the bottom of the connecting shell. By rotating screw one in the opposite direction, the wedge block moves in the opposite direction. Through the interlocking action of the dovetail tenon and the dovetail groove, the wedge push rods on both sides are pulled towards the middle, so that the sliders on both sides are inserted into the heat-conducting shell. Then, screw two is turned to move the sliders upward, further clamping and fixing the heat-conducting shell. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 and Figure 2This utility model provides an embodiment of an auxiliary heating device for an adjustable angle nonwoven fabric spinneret, comprising a base plate 1. Transmission mechanisms 2 are provided on both the left and right sides of the base plate 1. Two transmission mechanisms 2 are used to dynamically adjust the angle and distance of the heating device simultaneously. Clamping mechanisms 3 are provided at the bottom of each of the two transmission mechanisms 2 for clamping the heating device. Fixing mechanisms 4 are provided at the four corners of the bottom of the base plate 1. Multiple fixing mechanisms 4 are used to fix the detachable perforated plate at the bottom of the base plate 1. The transmission mechanism 2 includes two fixing blocks 201. The adjacent sides of the two fixing blocks 201 are fixedly connected to the upper middle part of the left and right ends of the base plate 1, respectively. Rotating rods 202 are rotatably connected to the inner sides of the two fixing blocks 201, providing fulcrums for the rotation of the rotating rods 202. Gears 203 are fixedly connected to the middle of the outer walls of the two rotating rods 202. When 202 rotates, it drives the gear 203 to rotate together. A rotating shell 204 is provided on the opposite side of the two fixed blocks 201. The front and rear ends of the two rotating rods 202 pass through the inner wall of the corresponding fixed blocks 201 and are fixedly connected to the front and rear sides of the inner wall of the corresponding rotating shell 204. When the rotating rod 202 rotates, it drives the rotating shell 204 to rotate. The tilt angle of the side of the rotating shell 204 adjacent to the base plate 1 is 30 degrees. According to the corresponding angle relationship, the rotation angle of the rotating shell 204 is ±30 degrees. A sliding groove 205 is provided on the opposite side of the interior of the two rotating shells 204. A rack 206 is slidably connected inside the two sliding grooves 205. The sliding groove 205 provides a limit for the rack 206. The two racks 206 are respectively meshed with the corresponding gears 203. A drive assembly 207 is provided on the right side of the two rotating rods 202. The drive assembly 207 is used to drive the transmission mechanism 2. The two drive components 207 each include a housing 2071. Adjacent sides of the two housings 2071 are fixedly connected to the left and right rear ends of the base plate 1, respectively. The rear ends of the two rotating rods 202 each pass through the corresponding rotating housing 204 and one side of the housing 2071, and are fixedly connected to a worm gear 2072. When the worm gear 2072 rotates, it drives the rotating rod 202 to rotate. A transmission rod 2075 is provided between adjacent housings 2071, enabling the drive components 207 on both sides to operate synchronously. The left and right ends of the rod 2075 pass through one side of the corresponding housing 2071 and are fixedly connected to the worm gear 2074. The two worm gears 2074 are respectively meshed with the corresponding worm wheel 2072. The upper right part of the right end of the housing 2071 is fixedly connected to the motor 2073. The output end of the motor 2073 passes through the right side of the corresponding housing 2071 and is fixedly connected to the right end of the corresponding worm gear 2074. The motor 2073 drives the worm gear 2074 to rotate, and the worm gear 2074 then drives the worm wheel 2072 to rotate. The fixing mechanism 4 includes multiple connecting columns 401, which are fixedly connected to the four corners of the bottom of the base plate 1. A support plate 402 is fixedly connected to one side of the outer wall of each of the multiple connecting columns 401. The support plate 402 can slide up and down on one side of the connecting column 401. A fixing plate 403 is rotatably connected to the middle of the outer wall of each of the multiple connecting columns 401. The support plate 402 provides limiting and support for the fixing plate 403. A positioning hole 404 is opened on one side of each of the multiple support plates 402 and the fixing plate 403. The positioning holes 404 opened on the support plates 402 and the fixing plate 403 correspond to each other. Bolts 405 are threaded to the inner side of each of the multiple positioning holes 404. After the bolts 405 pass through the positioning holes 404, the fixing plate 403 and the support plate 402 are connected together by nuts. Specifically, after the fiber is ejected from the spinneret, when it is necessary to dynamically adjust the angle and distance of the heating device according to changes in temperature and forming state, the motor 2073 is started. The motor 2073 drives the right worm 2074 to rotate. The right worm 2074 causes the left worm 2074 to rotate synchronously through the transmission rod 2075. The rotation of the left and right worms 2074 drives the corresponding worm wheels 2072 to rotate through a meshing relationship. The worm wheels 2072 then drive the corresponding rotating rod 202 to rotate. The rotating rod 202 is rotatably connected to the fixed block 201. The rotating rods 202 on both sides then drive the corresponding gears 203 to rotate. The rotating rod 202 is fixedly connected to the rotating shell 204. The sliding rack 206 inside the rotating shell 204 meshes with the gear 203. When the rotating rod 202 rotates, the rotating shell 204 and the gear 203 rotate accordingly. The rack 206 rotates within the rotating shell. The internal mechanism 204 is driven by the meshing rotation of gear 203 to move in a relatively linear manner. While the rack 206 is moving, it is driven to rotate by the rotating shell 204 to adjust the heating device to move closer to or further away from the fiber, and to adjust the angle and distance to ensure that the fiber maintains a suitable temperature throughout the molding process, thus avoiding fiber breakage due to uneven heat distribution. When the perforated plate at the bottom of the substrate 1 needs to be replaced, the fixing plate 403 can be released by pulling the bolt 405 out of the positioning hole 404. Then, the fixing plate 403 can be rotated 90 degrees to release the perforated plate, thus facilitating replacement. When the perforated plate needs to be installed, the fixing plate 403 is rotated 90 degrees in the opposite direction to align the positioning hole 404 of the fixing plate 403 with the positioning hole 404 of the support plate 402, and then the bolt 405 is screwed in to fix the perforated plate.

[0027] Reference Figure 3 , Figure 4 and Figure 5The clamping mechanism 3 includes two connecting shells 301. The tops of the two connecting shells 301 are respectively fixedly connected to the bottoms of corresponding racks 206. A lead screw 302 is rotatably connected to the inner center of each of the two connecting shells 301. A wedge block 303 is threadedly connected to the outer wall of each of the two lead screws 302. When the lead screw 302 rotates, the wedge block 303 can move back and forth. Dovetail tenons 305 are fixedly connected to the front and rear sides of each of the two wedge blocks 303. Wedge-shaped push rods 304 are slidably connected to the front and rear sides of the interior of each of the two connecting shells 301. Multiple wedge-shaped push rods 304... Each side is provided with a dovetail groove 306. One side of each of the multiple dovetail tenons 305 engages with the corresponding dovetail groove 306. The wedge block 303 is connected to the wedge push rods 304 on both sides through the engagement of the dovetail tenons 305 and the dovetail groove 306. The front and rear ends of the multiple wedge push rods 304 are fixedly connected with side plates 307. The bottom front and rear sides of the multiple wedge push rods 304 are rotatably connected with screw rods 309. The upper part of the outer wall of the multiple screw rods 309 is threaded with sliders 308. When the screw rods 309 rotate, they drive the sliders 308 to move up and down. Both connecting shells 301 have a heat-conducting shell 6 at their bottom. Both heat-conducting shells 6 have a heating wire 7 fixedly connected inside. The heating wire 7 is used to generate heat, which is then dissipated through the heat-conducting shell 6. Temperature sensors 8 are set in the middle of adjacent sides of both heat-conducting shells 6. The temperature of the fiber is sensed in real time by the temperature sensors 8, which facilitates real-time adjustment of the heating device. Each side of multiple side plates 307 has a limiting groove 5. One end of multiple sliders 308 is slidably connected to the inner side of the corresponding limiting groove 5. The limiting groove 5 provides guidance and limitation for the sliders 308. Specifically, when the heating device malfunctions, the clamping mechanism 3 can quickly replace the heating device. By rotating the lead screw 302, the wedge block 303 moves with the help of the threaded connection. The movement of the wedge block 303 pushes the wedge push rods 304 on both sides, causing them to move to the sides, thereby driving the slider 308 to move together, so that the heat-conducting shell 6 is not fixed, thus facilitating the replacement of the heat-conducting shell 6. The replaced heat-conducting shell 6 is placed at the bottom of the connecting shell 301. Then, by rotating the lead screw 302 in the opposite direction, the wedge block 303 moves in the opposite direction. Through the cooperation of the dovetail tenons 305 on both sides of the wedge block 303 and the dovetail grooves 306 on the wedge push rods 304, the wedge push rods 304 on both sides are pulled towards the middle, so that the sliders 308 on both sides are reinserted into the heat-conducting shell 6. Finally, by turning the lead screws 309 on both sides, the corresponding sliders 308 are moved upward, further clamping and fixing the heat-conducting shell 6.

[0028] Reference Figure 1 , Figure 2 and Figure 6The bottom front and rear sides of the substrate 1 are provided with moving grooves 9. The moving grooves 9 provide the sliding direction of the scraper 10. The scraper 10 is slidably connected to the left side inside the moving groove 9. The scraper 10 is pulled to scrape off the residue on the surface of the spinneret. The top of the substrate 1 is connected to the injection pipe 11. The melt enters the spinneret through the injection pipe 11, thereby extruding the fiber. The outer wall of the injection pipe 11 is threadedly connected to the threaded connecting cylinder 12. Specifically, by pulling the scraper 10 along the surface of the spinneret, residual polymer is scraped off, which can clean the spinneret, prevent polymer from clogging the nozzles, ensure the uniformity and stability of fiber extrusion, and extend the service life of the spinneret. The threaded connecting sleeve 12 can be connected to the extruder more conveniently and quickly, allowing the material to enter the spinneret.

[0029] Working Principle: When the fiber needs dynamic adjustment of the heating device's angle and distance to accommodate changes in temperature and forming state after being ejected from the spinneret, the motor 2073 is started. The motor 2073 drives the right worm gear 2074 to rotate, which in turn drives the left worm gear 2074 to rotate via the transmission rod 2075. As the left and right worm gears 2074 rotate, they mesh with each other, driving the corresponding worm wheels 2072 to rotate. The worm wheels 2072 then drive the corresponding rotating rods 202 to rotate. The rotating rods 202 are rotatably connected to the fixed block 201, which provides the fulcrum for rotation. The rotating rods 202 on both sides then drive the corresponding rotating rods 202 to rotate. The corresponding gear 203 rotates, while the rotating rods 202 on both sides are fixedly connected to the rotating shell 204. The sliding rack 206 inside the rotating shell 204 meshes with the gear 203. When the rotating rod 202 rotates, the rotating shell 204 and the gear 203 rotate accordingly. The rack 206 moves linearly relative to the gear 203 inside the rotating shell 204. At the same time, it is driven to rotate by the rotating shell 204. The rack 206 drives the heating device to move closer to or away from the fiber. The angle and distance are adjusted at the same time to avoid the heating direction from deviating from the fiber centerline, ensuring that the fiber maintains an appropriate temperature throughout the molding process and avoiding uneven heat distribution that could lead to fiber breakage. Furthermore, when the heating device malfunctions, the clamping mechanism 3 allows for quick replacement of the heating device. By rotating the lead screw 302, the wedge block 303 moves due to the threaded connection. When the wedge block 303 moves, it pushes the wedge push rods 304 on both sides to move, causing the sliders 308 to disengage from the heat-conducting shell 6, thus enabling the replacement of the heat-conducting shell 6. The replaced heat-conducting shell 6 is placed at the bottom of the connecting shell 301. The lead screw 302 is rotated in the opposite direction, and then the wedge block 303 moves in the opposite direction. Through the action of the dovetail tenon 305 and the dovetail groove 306 opened in the wedge push rod 304, the wedge push rods 304 on both sides are pulled towards the middle, thereby inserting the sliders 308 on both sides into the heat-conducting shell 6. Then, the lead screws 309 on both sides are turned, which will drive the corresponding sliders 308 to move upward, further clamping and fixing the heat-conducting shell 6.
