Description

Technical Field

[0001] This utility model relates to the technical field of polyester yarn drying, specifically a continuous polyester yarn drying device. Background Technology

[0002] The production of polyester yarn is a meticulous and systematic process. First, it begins with the selection of raw materials; high-quality polyester chips and filaments are the foundation for manufacturing high-quality polyester yarn. Next, these raw materials enter a melting device, where they are heated and melted to form a molten liquid. Subsequently, the molten liquid undergoes a series of stretching, straightening, and rotating processes in a spinning machine, causing the polyester fibers to tightly intertwine and form yarn. Simultaneously, the yarn is rapidly cooled to prevent deformation.

[0003] Considering production costs and cooling efficiency, direct contact cooling generally achieves rapid cooling. Due to water's high specific heat capacity, it cools much faster than air cooling, making water cooling the more common industrial method. After water cooling, a small amount of moisture remains on the surface of the shaped polyester yarn, necessitating drying.

[0004] Traditional drying methods mostly involve direct air drying or sun drying, which are labor-intensive and produce poor drying results, failing to meet large-volume demands. Meanwhile, some manufacturers use heat pump drying to process polyester yarn. High-pressure liquid refrigerant evaporates into a gaseous state in the evaporator after passing through an expansion valve, absorbing a large amount of heat energy from the air. The gaseous refrigerant is then compressed into a high-temperature, high-pressure liquid state by a compressor, and then enters a condenser to release heat. The heat generated in the condenser is then transferred to the drying chamber for further heating and drying via a hot air blower.

[0005] However, heat pump dryers consume a lot of energy, are not good for fabrics and yarns, and have a high initial investment. Regular cleaning of the filter and water tank is required. Furthermore, heat pump dryers have low operating efficiency, high internal temperatures, uneven drying, and can easily damage yarns; the emitted moisture can also increase indoor humidity.

[0006] Meanwhile, considering that a large amount of yarn needs to be dried in actual production, manufacturers will try to increase the amount of yarn dried each time. Staff usually place the yarn on multi-layer drying racks to improve drying efficiency.

[0007] However, existing drying equipment dries the yarn on the drying rack from top to bottom using hot air blowers. Yarn at the top of the drying rack receives high-intensity drying, while the drying intensity decreases with each layer. This results in the yarn at the bottom of the drying rack not receiving a good drying effect, while the yarn at the top of the drying rack is often over-dried, which may damage the fiber structure of the polyester yarn, leading to poor drying results. Summary of the Invention

[0008] The purpose of this invention is to provide a continuous drying device for polyester yarn to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A continuous drying device for polyester yarn includes a drying box, wherein multiple drying racks for receiving yarn are provided inside the drying box, and two sets of drying mechanisms located on the upper and lower sides of the drying racks are provided inside the drying box.

[0011] It also includes a control system that communicates with the two sets of drying mechanisms to control the two sets of drying mechanisms to alternately perform drying actions, wherein:

[0012] The drying mechanism includes a nozzle assembly and a drive component for driving the nozzle assembly to move stepwise within the drying chamber. The nozzle assembly is connected to a heating mechanism mounted on the drying chamber.

[0013] A continuous polyester yarn drying device as described above: the heating mechanism includes a hot air blower installed on the drying box and an air outlet pipe installed on the air outlet of the hot air blower. The top of the air outlet pipe is connected to two nozzle assemblies through a first hose and a second hose respectively, and a three-way solenoid valve for controlling the alternating conduction of the first hose and the second hose is also provided on the top of the air outlet pipe.

[0014] As described above, a continuous polyester yarn drying device includes two sets of guide columns horizontally mounted on the upper and lower sides of the drying chamber and a sliding member slidably mounted on the guide columns. The sliding member has a groove, a chain drive mechanism is provided on one side of the sliding member, and a cylindrical tube is mounted on one side of the chain drive mechanism. The cylindrical tube slides in the groove and cooperates with the chain drive mechanism to drive the sliding member to move back and forth. The chain drive mechanism is coaxially connected to a shaft rotatably mounted at one end of the drying chamber.

[0015] As described above, a continuous polyester yarn drying device includes a motor connected to the drying chamber and a Maltese cross mechanism drive unit fixedly mounted on the output shaft of the motor. One side of the Maltese cross mechanism drive unit is driven by a Maltese cross mechanism driven unit and a large gear fixed coaxially with the Maltese cross mechanism driven unit. The large gear meshes with a small gear fixedly mounted on the shaft.

[0016] A continuous polyester yarn drying device as described above: the nozzle assembly includes a fixed frame mounted on a sliding member and an air pipe mounted on the fixed frame. The first hose and the second hose are respectively connected to the upper and lower air pipes. Multiple air nozzles are installed on the air pipes, and the two sets of air nozzles are respectively located on the upper and lower sides of the drying rack.

[0017] As described above, a continuous polyester yarn drying device includes a control system comprising a power supply box installed on one side of the drying chamber and power-off switches A and B located on the upper and lower sides of the power supply box. The power-off switches A and B are remotely connected to four remote controllers, which are respectively installed at four positions on the inner wall of the drying chamber.

[0018] As described above, a continuous polyester yarn drying device is provided with top rods installed on the left and right sides of the two sliding parts, and the four top rods are respectively connected to four remote controllers. The A power-off switch and the B power-off switch respectively connect the motors at the upper and lower ends to the circuit.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting drying mechanisms on the upper and lower sides of the drying box, and through the cooperation of the drying mechanisms and the control system, the two sets of drying mechanisms can perform horizontal intermittent alternating movements, which allows hot air to penetrate from both the upper and lower directions of the drying rack. At the same time, the hot air blows alternately on both sides of the polyester yarn, thereby dispersing heat, reducing the possibility of fabric damage due to high temperature, improving heat exchange efficiency, and accelerating the overall drying speed.

[0020] In this utility model, the control system and heating mechanism can automatically switch the energy supply target as the upper and lower drying mechanisms operate alternately, saving energy consumed during equipment operation. Attached Figure Description

[0035] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0036] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0037] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0038] Please see Figures 1-13 In this embodiment of the present invention, a continuous drying device for polyester yarn includes a drying box 1, wherein multiple drying racks 2 for receiving yarn are provided inside the drying box 1, and two sets of drying mechanisms located on the upper and lower sides of the drying racks 2 are provided inside the drying box 1.

[0039] It also includes a control system that communicates with the two sets of drying mechanisms to control the two sets of drying mechanisms to alternately perform drying actions, wherein:

[0040] The drying mechanism includes a nozzle assembly and a drive component for driving the nozzle assembly to move stepwise within the drying chamber 1. The nozzle assembly is connected to a heating mechanism installed on the drying chamber 1.

[0041] In this embodiment, the control system communicates and controls the start and stop of the two drying mechanisms, and provides power to the two drying mechanisms to achieve step movement. At the same time, the heating mechanism provides gas to the nozzle assembly. When the control system communicates and controls the movement of the drying mechanism located on the upper side of the drying chamber 1, the driving component drives the nozzle assembly to move horizontally step by step. Then, when the nozzle assembly moves to one side, the control system communicates and controls the upper drying mechanism to stop, and communicates and controls the lower drying mechanism to start. The gas channel of the heating mechanism is switched to supply gas to the lower drying mechanism, so that the upper and lower drying mechanisms operate alternately.

[0042] In addition, when the control system communicates and controls the start and stop of the two sets of drying mechanisms, the upper and lower sets of drying mechanisms can move in steps. The upper and lower drying can allow hot air to penetrate the fabric from two directions, ensuring that both sides of the fabric are heated evenly. This avoids local overheating or under-drying caused by unilateral drying. Thus, the back-and-forth drying can evenly distribute hot air to all parts of the fabric, avoiding the problems of local overheating or under-drying. At the same time, as the drying mechanism moves in steps, it can allow hot air to blow alternately on both sides of the polyester yarn, thereby dispersing heat and reducing the possibility of fabric damage due to high temperature. The heating mechanism switches the supply of hot air in a timely manner, and together with the power distribution of the control system, it achieves the effect of saving energy.

[0043] As a further embodiment of this utility model, the heating mechanism includes a hot air blower 23 installed on the drying box 1 and an air outlet pipe 24 installed on the air outlet of the hot air blower 23. The top of the air outlet pipe 24 is connected to two nozzle assemblies through a first hose 7 and a second hose 17 respectively. The top of the air outlet pipe 24 is also provided with a three-way solenoid valve 25 for controlling the alternating conduction of the first hose 7 and the second hose 17.

[0044] In this embodiment, the air outlet of the hot air blower 23 is connected to the air outlet pipe 24, and the air outlet pipe 24, the first hose 7 and the second hose 17 are respectively connected to the three air inlets of the three-way solenoid valve 25. The first hose 7 and the second hose 17 supply air to the nozzle assembly.

[0045] In addition, the hot air from the hot air blower 23 will be distributed through the air outlet pipe 24 and then through the three-way solenoid valve 25, and the three-way solenoid valve 25 will distribute it to the first hose 7 or the second hose 17 to achieve the switching of hot air and realize the alternating supply of air to the upper and lower sets of nozzle assemblies.

[0046] As a further embodiment of this utility model, the driving component includes two sets of guide columns 6 horizontally installed on the upper and lower sides of the drying chamber 1 and a sliding member 8 slidably installed on the guide columns 6. The sliding member 8 is provided with a sliding groove 9. A chain drive mechanism 4 and a cylindrical cylinder 5 installed on one side of the chain drive mechanism 4 are provided on one side of the sliding member 8. The cylindrical cylinder 5 slides in the sliding groove 9 and cooperates with the chain drive mechanism 4 to drive the sliding member 8 to move back and forth. The chain drive mechanism 4 is coaxially connected to a shaft 3 rotatably installed at one end of the drying chamber 1.

[0047] In this embodiment, the slider 8 is slidably mounted on the guide post 6, and the cylindrical tube 5 on the chain drive mechanism 4 slides in the groove 9 on the slider 8. The movement of the cylindrical tube 5 in conjunction with the chain drive mechanism 4 causes the cylindrical tube 5 to slide continuously in the groove 9, thereby causing the slider 8 to move.

[0048] In addition, the movement of the chain drive mechanism 4 drives the sliding member 8 to move, thereby realizing the horizontal stepping movement of the drying mechanism.

[0049] As a further embodiment of this utility model, the driving component also includes a motor 14 connected to the drying chamber 1 and a Maltese cross movement driving component 15 fixedly sleeved on the output shaft of the motor 14. One side of the Maltese cross movement driving component 15 is driven by a Maltese cross movement driven component 16 and a large gear 21 coaxially fixed with the Maltese cross movement driven component 16. The large gear 21 meshes with a small gear 22 fixedly sleeved on the shaft 3.

[0050] In this embodiment, the driving component 15 of the Maltese cross movement is fixed to the output shaft of the motor 14. The driving component 15 of the Maltese cross movement and the driven component 16 of the Maltese cross movement are kinematically engaged. The large gear 21 is fixed to the shaft of the driven component 16 of the Maltese cross movement and rotates synchronously. The small gear 22 meshes with the large gear 21 for transmission. The purpose of increasing the rotational speed is achieved through the cooperation of the large gear 21 and the small gear 22.

[0051] In addition, the cooperation between the Maltese cross mechanism drive component 15 and the Maltese cross mechanism driven component 16 achieves the effect of converting continuous rotational motion into intermittent rotational motion, so as to achieve the purpose of intermittently sweeping hot air onto the polyester yarn and ensure the dispersion of heat during the drying operation.

[0052] As a further embodiment of this utility model, the nozzle assembly includes a fixed frame 10 mounted on the sliding member 8 and an air pipe 11 mounted on the fixed frame 10. The first hose 7 and the second hose 17 are respectively connected to the upper and lower air pipes 11. Multiple air nozzles 12 are installed on the air pipes 11, and the two sets of air nozzles 12 are respectively located on the upper and lower sides of the drying rack 2.

[0053] In this embodiment, the vent pipe 11 is fixed together with the sliding member 8 by the fixing bracket 10. Both the upper and lower vent pipes 11 are provided with multiple air nozzles 12. The upper and lower air nozzles 12 face the upper and lower sides of the drying rack 2 respectively. The first hose 7 and the second hose 17 supply air to the lower two vent pipes 11 respectively.

[0054] In addition, the sliding member 8 drives the upper and lower sets of jet nozzles 12 to blow hot air, and the first hose 7 and the second hose 17 distribute the hot air.

[0055] As a further embodiment of this utility model, the control system includes a power supply box 19 installed on one side of the drying oven 1, and an A power-off switch 20 and a B power-off switch 26 disposed on the upper and lower sides of the power supply box 19. The A power-off switch 20 and the B power-off switch 26 are remotely communicated with four remote controllers 18, which are respectively installed in four positions on the inner wall of the drying oven 1.

[0056] In this embodiment, power-off switch A 20 and power-off switch B 26 control the upper and lower circuits of the power supply box 19 respectively, and four remote controllers 18 are installed on the inner walls of both sides of the drying box 1. The four remote controllers 18 communicate and control with power-off switch A 20 and power-off switch B 26.

[0057] In addition, the four remote controllers 18 can communicate to control the switching of power-off switch A 20 and power-off switch B 26, and can control the circuit supply channel of power supply box 19.

[0058] As a further embodiment of this utility model, top rods 13 are installed on both sides of the two sliding members 8, and the four top rods 13 are respectively matched with four remote controllers 18. The A power-off switch 20 and the B power-off switch 26 respectively connect the upper and lower motors 14 to the circuit.

[0059] In this embodiment, top rods 13 are installed on both sides of the sliding member 8. The four top rods 13 correspond to the four remote controllers 18 installed inside the drying oven 1. The movement of the sliding member 8 controls the top rods 13 to trigger the remote controllers 18 to control the A power-off switch 20 and the B power-off switch 26.

[0060] In addition, the sliding member 8 drives the top rod 13 to move, triggering the corresponding remote controller 18, which changes the circuit supply channel of the control power supply box 19, thereby enabling the upper and lower sets of motors 14 to switch power supply, and thus realize the alternating operation of the upper and lower sets of drying equipment.

[0061] In use, the polyester yarn to be dried is first placed on the drying rack 2. The drying rack 2 adopts a multi-layer tray design, and each layer of the drying rack 2 has a grid-like hollow design to facilitate dehydration and drying. Then, the power supply box 19 supplies power to the motor 14. Due to the cooperation of the four remote controllers 18 with the A power-off switch 20 and the B power-off switch 26, the upper and lower sets of motors 14 cannot be powered at the same time. First, the power supply box 19 supplies power to the top motor 14. Then, the output shaft of the motor 14 is coaxial with the top Maltese cross movement drive element 15, which rotates, causing the Maltese cross movement drive element 15 and the Maltese cross movement to rotate from... The driving component 16 rotates, and then the driving component 15 of the Maltese cross mechanism rotates one revolution, causing the driven component 16 of the Maltese cross mechanism to rotate 60°, causing the driven component 16 of the Maltese cross mechanism to rotate intermittently. Then, the driven component 16 of the Maltese cross mechanism drives the large gear 21 to rotate, and the large gear 21 drives the small gear 22 to rotate. The cooperation between the large gear 21 and the small gear 22 can increase the speed of the small gear 22. Then, the small gear 22 drives the chain drive mechanism 4 at the top of the drying box 1 through the shaft 3. The transmission of the chain drive mechanism 4 will then drive the cylindrical cylinder 5 to move, so that the cylindrical cylinder 5 moves along the movement trajectory of the chain. At the same time, the cylindrical cylinder... The cylinder 5 slides within the chute 9, synchronously moving the sliding member 8. This causes the top vent pipe 11 and air nozzle 12 to move intermittently, significantly improving drying efficiency. At this time, the hot air blower 23 is activated, allowing the gas generated by the hot air blower 23 to pass through the air outlet pipe 24 and the three-way solenoid valve 25. The gas is then guided into the second flexible hose 17 via the three-way solenoid valve 25. Subsequently, the gas enters the top vent pipe 11 through the second flexible hose 17, and is then sprayed out from top to bottom by the air nozzle 12 to dry the polyester yarn. Later, when the top sliding member 8 moves to its rightmost position, the top rod 13 on the right side of the sliding member 8 touches the upper right corner. The remote controller 18 remotely controls the power supply box 19, causing the A power-off switch 20 to open and the B power-off switch 26 to close. At this time, the power supply box 19 stops supplying power to the top motor 14 and supplies power to the bottom motor 14. The bottom motor 14 starts and, in conjunction with the three-way solenoid valve 25, switches the air outlet to introduce gas into the first hose 7 to supply air to the bottom vent pipe 11. This allows the upper and lower drying mechanisms to dry alternately, which can fully dry both sides of the polyester yarn, improve the dehydration efficiency of the polyester yarn, and save energy.
