Description

Technical Field

[0001] The utility model relates to the technical field of textiles, in particular to a polyester filament melt direct spinning device. Background Art

[0002] The characteristic of polyester silk is that it can withstand chemicals and frequent washing, reducing fading and discoloration of clothing. Therefore, hotel uniforms, stone-ground blue denim clothing, sportswear or children's clothing are all made of polyester silk, and spinning components are required in the production of polyester silk.

[0003] In application number: CN202221039535.6, a melt-spinning stock solution composite polyester yarn production device is disclosed, including a worm gear rotatably mounted on a main module, a scraper fixed at the end on the outer side of the worm gear, a bracket fixed on the outer side of the main module, and a driving assembly installed on the bracket. An annular groove is opened on the outer side of the spinneret, and an annular part is fixed on the inner wall of the worm gear. The cross-sections of the annular groove and the annular part are both T-shaped, and the annular part is embedded in the annular groove, so that the worm gear is fixed on the spinneret while maintaining the rotation of the worm gear. The end of the scraper is fixed on the vertical side surface of the worm gear, and the inner side surface is in close contact with the surface of the spinneret, which is convenient for rotation to scrape off the melt adhering to the surface of the spinneret. The bracket is fixed on the body and is used to install the driving assembly. The melt-spinning stock solution composite polyester yarn production device has the advantages of reducing broken wires and intelligently detecting broken wires.

[0004] However, the intelligent broken wire detection device of the device has certain defects. The polyester yarn needs to block the light beam emitted by the laser emitter to avoid triggering the detection device. Since the polyester yarn itself is relatively thin, it is easy to deviate after being sprayed out from the spinneret, resulting in failure to block the light beam of the laser emitter, which easily leads to false broken wire alarms and causes certain troubles to the staff. In addition, the device lacks cooling treatment for the polyester yarn. Therefore, a polyester yarn melt direct spinning equipment is proposed, which can locate the position where the polyester yarn blocks the light beam to avoid false alarms caused by deviation of the polyester yarn. Utility Model Content

[0005] In view of the problems in the prior art, the utility model provides a polyester filament melt direct spinning device, which can locate the position where the polyester filament blocks the light beam, thereby avoiding the occurrence of false alarms caused by the deviation of the polyester filament.

[0006] The technical solution adopted by the utility model to solve its technical problems is a direct spinning device for polyester filament melt, including a direct spinning body. One side of the direct spinning body is fixedly installed with a first connecting plate and a second connecting plate. One side of the first connecting plate is fixedly connected with a first support rod, and one side of the second connecting plate is fixedly connected with a second support rod. A plurality of the first support rods and the second support rods are arranged opposite to each other, and the first support rods are directly above the second support rods.

[0007] A positioning plate is fixedly connected between the relatively arranged first support rod and the second support rod. There are multiple positioning plates. A perforation is horizontally opened inside the positioning plate. One side of the direct spinning body is fixedly installed with a spinneret. There are multiple spinnerets. The spinneret orifices of the spinnerets and the perforations are on the same horizontal line.

[0008] By adopting the above technical solution, setting the positioning plate between the first support rod and the second support rod allows the polyester filament to pass through the perforation of the positioning plate, thereby avoiding the situation of false triggering of the broken filament alarm when the polyester filament deviates.

[0009] Through the setting of the spray head, not only can the polyester filament be cooled, but also when the polyester filament breaks, the polyester filament can be sprayed out from the perforation to prevent the polyester filament from staying in the perforation without triggering the broken filament alarm.

[0010] Specifically, a laser receiver is fixedly installed at the top of the first support rod. The laser receiver is located at the inner bottom of the positioning plate. An indicator light is fixedly installed at the top of the second support rod, and a laser emitter is fixedly installed at the bottom of the second support rod. The laser emitter is located at the inner top of the positioning plate. A laser groove is vertically opened inside the positioning plate.

[0011] By adopting the above technical solution, when the direct spinning body starts to work and the spinneret sprays out the polyester filament, the polyester filament passes through the perforation of the positioning plate and then is wound up with the subsequent winding drum, etc. At this time, a part of the polyester filament is exactly in the perforation, which can block the laser emitted by the laser emitter. And even if the polyester filament deviates, the polyester filament inside the perforation will not deviate and can always block the laser.

[0012] Specifically, the laser groove is communicated with the inside of the perforation. The receiving end of the laser receiver, the output end of the laser emitter, and the laser groove are on the same vertical line.

[0013] By adopting the above technical solution, when the polyester filament passes through the perforation, the laser emitter and the laser receiver are operated. The laser emitted by the laser emitter will be emitted from the inside of the laser groove towards the laser receiver. However, when the laser passes through the perforation, it will be blocked by the polyester filament, and the laser receiver will not receive the laser and cannot trigger the broken filament alarm unless the polyester filament breaks.

[0014] Specifically, one side of multiple positioning plates is fixedly connected to one side of the mounting table, and a spray head is fixedly installed at the bottom of the mounting table, and there are multiple spray heads.

[0015] Specifically, a water pipe is fixedly inserted into the top of the mounting table, there are multiple water pipes, and multiple water pipes are respectively fixedly connected to and internally communicated with multiple spray heads, and valves are sleeved on the outer sides of multiple water pipes.

[0016] By adopting the above technical solution, when the polyester filament is normally wound, the water in the water pipe is sprayed out from the spray head by opening the valve, and the water mist sprayed by the spray head can just be sprayed onto the polyester filament coming out from the through hole. The water mist sprayed onto the polyester filament evaporates and absorbs heat, which can perform a preliminary cooling treatment on the polyester filament.

[0017] Advantages of the present utility model:

[0018] (1) For a polyester filament melt direct spinning device of the present utility model, by arranging a positioning plate between the first support rod and the second support rod, the polyester filament can pass through the through hole of the positioning plate, thereby avoiding the situation of false triggering of the broken wire alarm when the polyester filament deviates.

[0019] (2) For a polyester filament melt direct spinning device of the present utility model, through the arrangement of the spray head, not only can it provide a cooling effect for the polyester filament, but also when the polyester filament breaks, it can spray the polyester filament out of the through hole, avoiding the polyester filament staying in the through hole without triggering the broken wire alarm.

Specific Embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] In order to be able to locate the position where the polyester filament blocks the light beam and avoid the occurrence of false alarms due to the deviation of the polyester filament, as an embodiment of the present utility model, as Figures 1 - 3 shown, a polyester filament melt direct spinning device of the present utility model includes a direct spinning machine body 1. A first connecting plate 3 and a second connecting plate 6 are fixedly installed on one side of the direct spinning machine body 1. A first support rod 4 is fixedly connected to one side of the first connecting plate 3. A second support rod 7 is fixedly connected to one side of the second connecting plate 6. A plurality of the first support rods 4 and the second support rods 7 are arranged opposite to each other, and the first support rod 4 is directly above the second support rod 7;

[0027] A positioning plate 5 is fixedly connected between the relatively arranged first support rod 4 and the second support rod 7. There are a plurality of the positioning plates 5. A perforation 11 is horizontally opened inside the positioning plate 5. A spinneret 2 is fixedly installed on one side of the direct spinning machine body 1. There are multiple spinnerets 2. The spinning nozzle of the spinneret 2 and the perforation 11 are on the same horizontal line.

[0028] During use, when the direct spinning machine body 1 starts to work and the spinneret 2 sprays out polyester filaments, the polyester filaments are passed through the perforations 11 of the positioning plate 5 and then wound up with subsequent take-up reels, etc. At this time, a part of the polyester filament is just located in the perforation 11, which can block the laser emitted by the laser emitter 13, and even if the polyester filament deviates, the polyester filament inside the perforation 11 will not deviate and can always block the laser.

[0029] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that a laser receiver 16 is fixedly installed on the top of the first support rod 4. The laser receiver 16 is located at the inner bottom of the positioning plate 5. An indicator light 8 is fixedly installed on the top of the second support rod 7. A laser emitter 13 is fixedly installed at the bottom of the second support rod 7. The laser emitter 13 is located at the inner top of the positioning plate 5. A laser groove 15 is vertically opened inside the positioning plate 5.

[0030] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that the laser groove 15 is internally communicated with the perforation 11, and the receiving end of the laser receiver 16, the output end of the laser emitter 13 and the laser groove 15 are on the same vertical line.

[0031] In use, when the polyester filament passes through the perforation 11, the laser emitter 13 and the laser receiver 16 are operated. The laser emitted by the laser emitter 13 will be emitted from inside the laser groove 15 towards the laser receiver 16. However, when the laser passes through the perforation 11, it will be blocked by the polyester filament, and the laser receiver 16 will not receive the laser, so the broken filament alarm cannot be triggered, unless the polyester filament breaks.

[0032] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that one side of each of the plurality of positioning plates 5 is fixedly connected to one side of the mounting table 12, and a spray head 14 is fixedly installed at the bottom of the mounting table 12, and there are multiple spray heads 14.

[0033] Exemplarily, as Figures 1 - 3 shown, the present utility model further includes that a water pipe 9 is fixedly inserted into the top of the mounting table 12, there are multiple water pipes 9, the multiple water pipes 9 are respectively fixedly connected to and internally communicated with the multiple spray heads 14, and valves 10 are sleeved on the outer sides of the multiple water pipes 9.

[0034] In use, when the polyester filament is normally wound up, by opening the valve 10, the water in the water pipe 9 is sprayed out from the spray head 14. The water mist sprayed out by the spray head 14 can just spray onto the polyester filament coming out from the perforation 11. The water mist sprayed onto the polyester filament evaporates and absorbs heat, which can perform a preliminary cooling treatment on the polyester filament.

[0035] It should be noted that in order to prevent the broken polyester filament from staying inside the perforation 11, when the polyester filament breaks, due to the downward spraying force of the spray head 14 and the gravitational relationship of the water mist attached to the polyester filament, the polyester filament on the right side of the positioning plate 5 will be sprayed out from the perforation 11, and the polyester filament on the left side of the positioning plate 5 will naturally be wound up by the winding cylinder.

[0036] When the present utility model is in use, when the direct spinning machine body 1 starts to work and the polyester filament is sprayed out from the spinneret 2, the polyester filament is passed through the perforation 11 and then wound up with subsequent winding cylinders and the like. At this time, when the polyester filament passes through the perforation 11, the laser emitter 13 and the laser receiver 16 are operated. The laser emitted by the laser emitter 13 will be emitted from inside the laser groove 15 towards the laser receiver 16. However, when the laser passes through the perforation 11, it will be blocked by the polyester filament, and the laser receiver 16 will not receive the laser, so the broken filament alarm cannot be triggered. When the polyester filament is offset due to external factors, the polyester filament in the perforation 11 will not be offset either, and always blocks the laser emitted by the laser emitter 13, so that no false broken filament alarm will occur. At the same time, when the polyester filament is normally wound up, by opening the valve 10, the water in the water pipe 9 is sprayed out from the spray head 14. The water mist sprayed out by the spray head 14 can just spray onto the polyester filament coming out from the perforation 11. The water mist sprayed onto the polyester filament evaporates and absorbs heat, which can perform a preliminary cooling treatment on the polyester filament.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and the above-described embodiments and descriptions in the specification are only for explaining the principles of the present utility model.
