Description

Technical Field

[0001] This utility model relates to the technical field of drying and shaping devices, and in particular to a uniform heat drying and shaping device for polyester yarn. Background Technology

[0002] Polyester is an important type of synthetic fiber and is the commercial name for polyester fiber in my country. It is a fiber-forming polymer—polyethylene terephthalate (PET)—obtained from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions. The fiber is then spun and post-processed. Currently, heat-setting equipment is required in the processing of polyester filaments; however, most existing heat-setting devices have poor heating effects and uneven heating, causing polyester filament breakage.

[0003] Chinese utility model patent CN222064738U discloses a heat-setting device for polyester filaments with uniform heating, belonging to the field of polyester filament heat-setting technology. The device includes four columns, with a common housing fixedly connected to the top of each column. Two hot air blowers are fixedly installed on the top of the housing, and the output ends of the two hot air blowers are fixedly connected to a common air duct. Several air outlets are fixedly connected to the bottom of the air duct. Steam recovery plates are fixedly connected to both sides of the inner wall of the housing. By controlling the operation of the blowers, air can be blown into the interior of the housing through the air duct and air outlets, achieving uniform heating. The steam recovery plates absorb the water vapor generated during drying and collect it in a recovery box through a recovery pipe, preventing water vapor from dripping. By controlling the operation of the heating plates, the polyester filaments can be heated and dried to achieve heat-setting.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: The above-mentioned device collects water vapor generated during the drying process through a recycling box set on the bottom wall of the box. In actual use, sometimes the polyester filaments break during the drying process. The staff needs to re-pass the broken polyester filaments through both sides of the box. At this time, the overall design of the box makes it difficult to connect the polyester filaments, resulting in a poor user experience. Utility Model Content

[0005] To solve the above problems, this utility model provides a device for uniform heat drying and shaping of polyester yarn.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a polyester yarn uniform heat drying and shaping device, comprising a box body, a column installed on the bottom surface of the box body, a first fixing plate and a second fixing plate respectively arranged on both sides of the box body, a feeding roller arranged on the first fixing plate, a take-up roller arranged on the second fixing plate, a hot air fan arranged on the box body, an air duct connected to the hot air fan, and a heating plate arranged inside the box body. A placement groove is provided on the side wall of the box body, and a sealing groove is provided on the inner top wall of the placement groove. A baffle plate is slidably arranged in the sealing groove, and a fixing component for fixing the baffle plate is provided on the baffle plate.

[0007] By adopting the above technical solution, when workers need to dry polyester filaments, they need to connect one end of the polyester filament to the feed roller and pass the other end through the feed inlet on the chamber, thus extending one end of the polyester filament into the chamber. Then, the workers need to close the fixing components and slide the baffle plate upwards to move it to its highest point and maintain stability, thereby exposing the polyester filament inside the chamber to their view. This reduces the difficulty of connecting the end of the polyester filament away from the feed roller to the take-up roller. Subsequently, the workers need to turn on the heating plate and hot air fan in sequence. The warm air, combined with the hot air fan and air ducts, gradually increases the temperature inside the chamber, thus drying and shaping the polyester filament, thereby improving the worker's experience.

[0008] Furthermore, the two opposite sidewalls of the barrier plate are provided with fixing grooves, and the inner walls of the two fixing grooves are provided with moving grooves. The sidewalls of the barrier plate are provided with threaded grooves that communicate with the two moving grooves. The fixing assembly includes two fixing rods that are slidably disposed in the two fixing grooves, two tension springs that are fixed in sequence on the sidewalls of the two fixing rods near the axis of the threaded grooves, and a driving device disposed on the barrier plate for simultaneously driving the two fixing rods. The other ends of the two tension springs are fixed in sequence on the inner walls of the corresponding fixing grooves.

[0009] By employing the above technical solution, when polyester filaments break during the drying process, workers need to reconnect the broken filaments to the take-up rollers. At this point, workers need to turn off the drive device, which allows the two fixed rods to automatically reset under the action of the tension springs, thus separating the baffle from the inner wall of the placement trough. Subsequently, workers need to slide the barrier plate upwards to keep the placement trough open, thereby reducing the difficulty of reconnecting the polyester filaments.

[0010] Furthermore, the driving device includes a threaded rod threaded into the threaded groove and two movable rods sequentially fixed to the sidewalls of the two fixed rods near the axis of the threaded groove. Inclined surfaces are provided on the edges where the sidewalls of the two movable rods near the axis of the threaded groove intersect with the sidewalls near the opening of the threaded groove.

[0011] By adopting the above technical solution, when workers need to dry polyester filaments, they must close the placement tank. At this time, workers need to slide the partition plate downwards to make it press against the bottom wall of the placement tank. Further, workers need to rotate the threaded rod, which moves it closer to the moving groove, causing it to simultaneously press against the inclined surfaces on the two moving rods. This moves the two moving rods away from each other, causing the two fixed rods to follow the moving rods and press against the inner wall of the placement tank, thus stabilizing the partition plate.

[0012] Furthermore, each of the two opposing side walls of the barrier plate is provided with a barrier groove that communicates with the corresponding fixing groove. Each of the two barrier grooves is slidably provided with a baffle, and the two baffles are sequentially fixed to the adjacent fixing rods.

[0013] By adopting the above technical solution, when the two moving rods move away from each other, the two baffles are successively pressed against the two inner walls of the placement groove under the action of the two moving rods, thereby sealing the placement groove and reducing the probability of hot air moving out of the chamber through the placement groove, thus improving the drying effect of the hot air blower.

[0014] Furthermore, the side wall of the threaded rod is provided with an internal hexagonal groove to reduce the difficulty for workers to rotate the threaded rod.

[0015] By adopting the above technical solution, when the worker needs to rotate the threaded rod, the worker only needs to connect the Allen wrench to the Allen socket and rotate the Allen wrench to rotate the threaded rod, thereby reducing the difficulty for the worker to fix the partition plate.

[0016] Furthermore, sealing strips are provided on the sidewalls of the two baffles that are far apart from each other and on the bottom surface of the barrier plate.

[0017] By adopting the above technical solution, the sealing strip improves the sealing effect of the partition plate on the mounting groove, thereby further reducing the probability of hot air moving out of the box through the mounting groove, and thus improving the drying effect of the hot air blower.

[0018] Furthermore, a magnet block is embedded on the upper surface of the barrier plate, and a magnet strip is installed on the inner top wall of the closed groove, with the magnet strip and the magnet block attracting each other.

[0019] By adopting the above technical solution, when the staff slides the partition upward, the magnetic strip and the magnetic block attract each other, thereby keeping the partition stable and reducing the probability that the partition will interfere with the staff's connection of polyester yarn.

[0020] Furthermore, a mounting block is installed at the lower end of the side wall of the barrier to reduce the difficulty for workers to slide the barrier.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. In this application, when the worker needs to dry the polyester filament, the worker needs to connect one end of the polyester filament to the feed roller and pass the other end of the polyester filament through the feed inlet on the box, thus extending one end of the polyester filament into the box. Then, the worker needs to close the fixing assembly and slide the baffle plate upwards, moving the baffle plate to its highest point and maintaining stability, thereby exposing the polyester filament inside the box to the view, reducing the difficulty for the worker to connect the end of the polyester filament away from the feed roller to the take-up roller. Subsequently, the worker needs to turn on the heating plate and the hot air blower in sequence, allowing the warm air to gradually increase the temperature inside the box under the combined action of the hot air blower and the air duct, thereby drying and shaping the polyester filament, thus improving the worker's user experience.

[0023] 2. In this application, when the polyester filament breaks during the drying process, the operator needs to reconnect the broken polyester filament to the take-up roller. At this time, the operator needs to turn off the drive device, which will allow the two fixed rods to automatically reset under the action of the tension spring, thereby separating the baffle from the inner wall of the placement groove. Subsequently, the operator needs to slide the barrier plate upward to keep the placement groove open, thus reducing the difficulty for the operator to connect the polyester filament;

[0024] 3. In this application, when the two moving rods move in a direction away from each other, the two baffles are successively pressed against the two inner walls of the mounting groove under the action of the two moving rods, thereby sealing the mounting groove and reducing the probability of hot air moving out of the chamber through the mounting groove, thus improving the drying effect of the hot air blower.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-6 As shown in the embodiment of this application, a polyester filament uniform heat drying and shaping device is disclosed, including a box body 1, a column 11, a first fixing plate 2, a second fixing plate 21, a feed roller 22, a take-up roller 23, a hot air blower 3, an air duct 31, a heating plate 4, a barrier plate 5, a fixing assembly 6, a baffle 81, a sealing strip 83, a magnet block 84, and a magnet strip 85. The column 11 is installed on the bottom surface of the box body 1. The first fixing plate 2 and the second fixing plate 21 are plate-shaped structures, and the first fixing plate 2 and the second fixing plate 21 are respectively arranged on both sides of the box body 1. The feed roller 22 is arranged on the first fixing plate 2, and the take-up roller 23 is arranged on the second fixing plate 21. The hot air blower 3 is arranged on the box body 1, the air duct 31 is a circular tube structure, the air duct 31 is connected to the hot air blower 3, and the heating plate 4 is arranged inside the box body 1. The side wall of the housing 1 is provided with a placement groove 41, and the inner top wall of the placement groove 41 is provided with a sealing groove 42. The barrier plate 5 is a rectangular plate structure and is slidably disposed in the sealing groove 42.

[0034] Each of the two opposing sidewalls of the barrier plate 5 has a fixing groove 51, and each of the inner walls of the two fixing grooves 51 has a moving groove 52. The sidewall of the barrier plate 5 also has a threaded groove 53 that communicates with both moving grooves 52. A fixing assembly 6 is mounted on the barrier plate 5 to fix it. The fixing assembly 6 includes a fixing rod 61, a tension spring 62, and a driving device 7. The fixing rod 61 is a rectangular rod-shaped structure, and two fixing rods 61 are provided and slidably disposed within the two fixing grooves 51. Two tension springs 62 are provided, with one end of each tension spring fixed to the sidewall of the two fixing rods 61 near the axis of the threaded groove 53, and the other end of each tension spring 62 fixed to the inner wall of the corresponding fixing groove 51.

[0035] When a polyester filament breaks during the drying process, the operator needs to reconnect the broken filament to the take-up roller 23. At this point, the operator needs to turn off the drive device 7, which will cause the two fixed rods 61 to automatically reset under the action of the tension spring 62, thereby separating the baffle 81 from the inner wall of the placement groove 41. Subsequently, the operator needs to slide the barrier plate 5 upwards to keep the placement groove 41 open, thus reducing the difficulty of connecting the polyester filaments.

[0036] The driving device 7 is mounted on the baffle plate 5 and is used to simultaneously drive two fixed rods 61. The driving device 7 includes a threaded rod 71 and a moving rod 72. The threaded rod 71 is threaded into the threaded groove 53. The moving rod 72 is a rectangular rod structure. There are two moving rods 72, which are fixed in sequence to the side walls of the two fixed rods 61 near the axis of the threaded groove 53. Inclined surfaces are formed on the edges where the side walls of the two moving rods 72 near the axis of the threaded groove 53 intersect with the side walls near the opening of the threaded groove 53.

[0037] When the polyester filaments need to be dried, the placement trough 41 needs to be sealed. At this time, the worker needs to slide the partition plate downwards to press it against the bottom wall of the placement trough 41. Further, the worker needs to rotate the threaded rod 71, which moves it closer to the moving trough 52, causing it to press against the inclined surfaces of the two moving rods 72. This moves the two moving rods 72 away from each other, causing the two fixed rods 61 to move with the moving rods 72 and press against the inner wall of the placement trough 41, thus stabilizing the partition plate.

[0038] The two side walls of the barrier plate 5 are provided with barrier grooves 8 that communicate with the corresponding fixing grooves 51. The baffle 81 is a rectangular plate structure. There are two baffles 81 and they are slidably arranged in the two barrier grooves 8 in sequence. The two baffles 81 are fixed to the adjacent fixing rods 61 in sequence.

[0039] When the two moving rods 72 move away from each other, the two baffles 81 press against the two inner walls of the mounting groove 41 under the action of the two moving rods 72, thereby sealing the mounting groove 41 and reducing the probability of hot air moving out of the box 1 through the mounting groove 41, thus improving the drying effect of the hot air blower 3.

[0040] To reduce the difficulty for workers in fixing the partition, the threaded rod 71 is provided with an internal hexagonal slot 82 on its side wall to simplify the process of rotating the rod. When workers need to rotate the threaded rod 71, they only need to connect the internal hexagonal wrench to the slot 82 and rotate the wrench to rotate the threaded rod 71, thus reducing the difficulty of fixing the partition.

[0041] Three sealing strips 83 are provided and are arranged sequentially on the side walls of the two baffles 81 that are far apart from each other and on the bottom surface of the baffle plate 5. The sealing strips 83 improve the sealing effect of the baffle plate on the mounting groove 41, thereby further reducing the probability of hot air moving to the outside of the box 1 through the mounting groove 41, and thus improving the drying effect of the hot air blower 3.

[0042] The magnet block 84 is a block-shaped structure and is embedded in the upper surface of the barrier plate 5. The magnet strip 85 is a sheet-shaped structure and is installed on the inner top wall of the closed groove 42, and the magnet strip 85 and the magnet block 84 are attracted to each other. When the operator slides the partition upward, the magnet strip 85 and the magnet block 84 attract each other, thereby stabilizing the partition and reducing the probability that the partition will interfere with the operator's connection of polyester filaments.

[0043] To reduce the difficulty for workers to slide the barrier 5, a mounting block 9 is installed at the lower end of the side wall of the barrier 5.

[0044] The operating principle of the polyester filament uniform heat drying and shaping device in this embodiment is as follows: When the operator needs to dry the polyester filament, one end of the polyester filament needs to be connected to the unwinding roller 22, and the other end of the polyester filament needs to be passed through the feed inlet on the box 1, so that one end of the polyester filament extends into the box 1. Then, the operator needs to close the fixing component 6 and slide the baffle plate 5 upward, so that the baffle plate 5 moves upward to the highest point and remains stable, thereby exposing the polyester filament inside the box 1 to the line of sight, thus reducing the difficulty for the operator to connect the end of the polyester filament away from the unwinding roller 22 to the take-up roller 23. Subsequently, the operator needs to turn on the heating plate 4 and the hot air blower 3 in sequence, so that the warm air, under the combined action of the hot air blower 3 and the air duct 31, gradually increases the temperature inside the box 1, thereby drying and shaping the polyester filament, thus improving the operator's user experience.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
