Description

Technical Field

[0001] The present application relates to the field of yarn drying technical equipment, and in particular to an efficient yarn drying device. Background Art

[0002] Yarn is a thin, thread-like material made up of fibers or strands, commonly used in textiles and weaving. Yarn can be made from natural or synthetic fibers, and they vary in thickness and texture, making them suitable for different types of textiles. Yarn is an important material for making clothing and home textiles.

[0003] In order to meet various color requirements, the yarn needs to be dyed before knitting. The dyed yarn needs to be quickly dried using a drying device. The existing drying equipment usually includes a shell, a conveyor for conveying the yarn is provided inside the shell, and several hot air blowers are installed side by side on the shell along the conveying direction of the conveyor. The yarn passes through the action range of each hot air blower during the conveying process of the conveyor and is gradually dried.

[0004] With respect to the above-mentioned related technologies, the yarn contacts the action range of each hot air blower one by one during the conveying process, and the hot air blower without the yarn passing through is in an idling state, resulting in a waste of hot air. Summary of the invention

[0005] In order to fully utilize the hot air from the hot air blower and improve the drying efficiency, the present application provides an efficient yarn drying device.

[0006] The present application provides an efficient yarn drying device, which adopts the following technical solution:

[0007] A high-efficiency yarn drying device comprises a shell, an opening for yarn to enter and exit the shell is formed on the shell, a conveyor for conveying yarn is formed inside the shell, a plurality of hot air blowers for blowing hot air to the yarn are arranged side by side on the shell, the output end of the hot air blower is connected to a hot air pipe for guiding the hot air to the conveyor, a connecting pipe for connecting the hot air pipes is provided in the shell, a baffle for blocking hot air is vertically slidably connected to the pipe mouth of the hot air pipe, the baffle is provided with a vent, a tray for carrying yarn is provided on the conveyor, a push rod is provided on the tray for driving the baffle to slide upward when the tray passes through the hot air pipe, and when the push rod lifts the baffle, the vent faces the pipe mouth of the hot air pipe.

[0008] By adopting the above technical solution, when no tray passes by, the baffle blocks the hot air duct. When the tray carrying the yarn passes through the hot air duct, the top rod drives the baffle to slide upward, so that the vent moves to a position directly opposite the hot air duct opening, and the hot air is blown out through the vent and blown toward the yarn. The hot air from other hot air ducts is blown toward the hot air duct through the connecting pipe and blown toward the yarn. This makes full use of the hot air from the hot air blower and helps to improve the drying efficiency.

[0009] Optionally, the shell is provided with a plurality of exhaust fans for timely exhausting the water vapor in the shell.

[0010] By adopting the above technical solution, the moisture in the yarn is fully evaporated into water vapor in the shell. If the water vapor is not discharged in time, it will be detrimental to the subsequent drying of the yarn. The exhaust fan can promote the flow of gas inside and outside, help to discharge the water vapor in the shell in time, and maintain the drying efficiency of the drying device.

[0011] Optionally, the hot air pipe is provided with an elastic member for driving the baffle to slide downward.

[0012] By adopting the above technical solution, when the tray passes through the hot air duct, the push rod lifts the baffle and compresses the elastic member. When the push rod leaves the current hot air duct area with the tray, the elastic member rebounds and drives the baffle to slide down and reset quickly.

[0013] Optionally, a turntable is rotatably connected to the tray and the rotation axis is vertically arranged. The yarn is placed on the turntable. A driven gear ring is coaxially fixedly connected to the periphery of the turntable. The side wall of the shell is provided with a driving rack meshing with the driven gear ring.

[0014] By adopting the above technical solution, the hot air blower is arranged side by side on the side wall of the same side as the shell, which may cause uneven heating of the yarn on the same tray. A tray for carrying yarn is rotatably connected to the tray, and the driven gear ring is engaged with the driving rack. The driven gear ring can drive the turntable to rotate with the movement of the tray, so that the yarn at each position on the tray can be heated evenly, which helps to improve the drying effect.

[0015] Optionally, an abutment rod is provided in the shell, and the abutment rod is arranged on the side wall opposite to the driving rack in the shell. The length direction of the abutment rod is parallel to the conveying direction of the conveyor. When the driven gear ring is engaged with the driving rack, the tray abuts against the abutment rod.

[0016] By adopting the above technical solution, the abutment rod can keep the driven gear ring in meshing with the driving rack during movement, thereby preventing the driven gear ring from being separated from the driving rack.

[0017] Optionally, a follower wheel is provided on the tray, and the follower wheel abuts against the abutment rod.

[0018] By adopting the above technical solution, the follower wheel can convert the sliding friction between the pallet and the abutment rod into rolling friction with less resistance, which helps to reduce the resistance of the pallet moving forward with the conveyor.

[0019] Optionally, a plurality of follower wheels are arranged side by side and all abut against the abutment rod.

[0020] By adopting the above technical solution, multiple follower wheels that abut against the abutment rod at the same time help to keep the pallet in the same direction as it moves forward with the conveyor, avoid the pallet from rotating, and help to improve the stability of the device operation.

[0021] Optionally, a protective curtain is provided at the opening of the shell to prevent hot air from blowing out.

[0022] By adopting the above technical solution, workers are required to load and unload the yarn at the opening of the shell. If hot air blows out from the opening, it will be detrimental to the working environment of the workers. Setting a protective curtain can reduce the amount of hot air outflow at the opening, which helps to improve the working environment of the workers.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When no tray passes through the hot air pipe, the baffle blocks the hot air pipe. When the tray carrying the yarn passes through the hot air pipe, the top rod drives the baffle to slide upward, and the vent moves to the position facing the hot air pipe opening. The hot air is blown out through the vent and blows toward the yarn. The hot air from other hot air pipes is blown toward the hot air pipe where the tray passes through the connecting pipe and blows toward the yarn, which makes full use of the hot air from the hot air blower and helps to improve the drying efficiency.

[0025] 2. The moisture in the yarn fully evaporates into water vapor in the shell. If the water vapor is not discharged in time, the humidity in the shell will increase, which is not conducive to the subsequent drying of the yarn. The exhaust fan can promote the gas circulation inside and outside the shell, which helps to discharge the water vapor in the shell in time and maintain the drying efficiency of the drying device.

[0031] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0032] The embodiment of the present application discloses an efficient yarn drying device.

[0033] Reference Figure 1 and Figure 2 , an efficient yarn drying device, including a shell 1, an opening 11 for yarn to enter and exit the shell 1 is provided on the shell 1, a conveyor 2 for conveying yarn is provided in the shell 1, and a plurality of hot air blowers 3 for blowing hot air to the yarn are arranged side by side on the shell 1. In the traditional drying mode, the yarn contacts the action range of each hot air blower 3 one by one during the conveying process, and the hot air blower 3 without yarn passing through is in an idling state, resulting in a waste of hot air. In the present application, a hot air pipe 4 is connected to the output end of the hot air blower 3, which is used to guide the hot air to the yarn on the conveyor 2. A connecting pipe 43 is provided in the shell 1, and the connecting pipe 43 connects the various hot air pipes 4. A baffle 41 is vertically slidably connected to the pipe mouth of the hot air pipe 4, and the baffle 41 is provided with a vent 411. In the natural state, the baffle 41 blocks the hot air pipe 4. A tray 5 is transported on the conveyor 2, and the tray 5 is used to transport yarn. A horizontally arranged top rod 51 is fixedly connected to the tray 5. When the tray 5 passes through the hot air pipe 4, the top rod 51 drives the baffle 41 to slide upward. When the top rod 51 lifts the baffle 41, the vent 411 moves to a position facing the pipe opening of the hot air pipe 4, and the hot air is blown out through the vent 411 and blown toward the yarn. The hot air from other hot air pipes 4 is blown toward the hot air pipe 4 through the connecting pipe 43 and blown toward the yarn, thereby making full use of the hot air from the hot air blower 3 and helping to improve the drying efficiency.

[0034] Reference Figure 1 and Figure 2 The moisture in the yarn is fully evaporated into water vapor in the housing 1. If the water vapor is not discharged in time, the humidity in the housing 1 will increase, which is not conducive to the subsequent drying of the yarn. Several exhaust fans 6 are installed side by side on the housing 1 to promote the flow of gas inside and outside, help to discharge the water vapor in the housing 1 in time, and maintain the drying efficiency of the drying device.

[0035] Reference Figure 2 and Figure 3 The hot air duct 4 is provided with an elastic member 42 for driving the baffle 41 to slide downward. When the tray 5 passes through the hot air duct 4, the push rod 51 lifts the baffle 41 and the elastic member 42 is compressed. When the push rod 51 leaves the current hot air duct 4 area with the tray 5, the elastic member 42 rebounds, which can drive the baffle 41 to slide downward quickly and reset.

[0036] Reference Figure 1 and Figure 2The hot air blower 3 is arranged side by side on the side wall of the housing 1, which may cause uneven heating of the yarn on the same tray 5. A turntable 52 is rotatably connected to the tray 5 and the rotation axis is vertically arranged. The yarn is placed on the turntable 52. A driven gear ring 521 is coaxially fixedly connected to the outer periphery of the turntable 52. The side wall of the housing 1 is provided with a driving rack 12 meshing with the driven gear ring 521. The driven gear ring 521 can drive the turntable 52 to rotate as the tray 5 moves, so that the yarn at each position on the tray 5 can be heated evenly, which helps to improve the drying effect.

[0037] Reference Figure 1 and Figure 2 A contact rod 13 is provided in the shell 1. The contact rod 13 is arranged on the side wall opposite to the driving rack 12 in the shell 1. The length direction of the contact rod 13 is parallel to the conveying direction of the conveyor 2. When the driven gear ring 521 is engaged with the driving rack 12, the tray 5 abuts against the contact rod 13, so that the driven gear ring 521 maintains an engaged state with the driving rack 12 during movement, preventing the driven gear ring 521 from disengaging from the driving rack 12.

[0038] Reference Figure 2 and Figure 4 The tray 5 is provided with a follower wheel 53 that abuts against the abutment rod 13, which can convert the sliding friction between the tray 5 and the abutment rod 13 into rolling friction with less resistance, which helps to reduce the resistance of the tray 5 moving forward with the conveyor 2.

[0039] Reference Figure 2 and Figure 4 A plurality of follower wheels 53 are arranged side by side and all abut against the abutment rod 13, which helps to keep the direction of the tray 5 unchanged while it moves forward with the conveyor 2, prevents the tray 5 from rotating, and helps to improve the stability of the device operation.

[0040] Reference Figure 1 and Figure 2 The opening 11 of the shell 1 requires workers to load and unload yarn. If hot air blows out from the opening 11, it will be detrimental to the working environment of the workers. A protective curtain 14 for reducing the blowing of hot air is provided at the opening 11 of the shell 1, which can reduce the amount of hot air outflow at the opening 11 and help improve the working environment of the workers.

[0041] The implementation principle of an efficient yarn drying device in the embodiment of the present application is as follows: the yarn is placed on the turntable 52 of the tray 5, and the yarn is transported through the housing 1, and the hot air blower 3 blows hot air into the housing 1. When there is no tray 5 passing by, the baffle 41 blocks the hot air pipe 4. When the tray 5 passes by the hot air pipe 4, the top rod 51 drives the baffle 41 to slide upward, so that the vent 411 moves to a position facing the hot air pipe 4. The hot air is blown out through the vent 411 and blown toward the yarn. The hot air from other hot air pipes 4 is blown toward the hot air pipe 4 where the tray 5 passes at this time through the connecting pipe 43 and blown toward the yarn, which makes full use of the hot air from the hot air blower 3 and helps to improve the drying efficiency.

[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
