Description

Technical Field

[0001] The utility model relates to the technical field of nylon filament processing equipment, and particularly relates to a nylon filament drying device. Background Art

[0002] In the production process of nylon filaments, drying is a key step, which directly affects the quality and production efficiency of nylon filaments.

[0003] Referring to the "Nylon Filament Processing and Drying Equipment" with the authorized announcement number CN 221344959 U, it includes a working box, a connecting groove and a mounting rack. The connecting groove is opened in the middle of the front and rear side walls of the inner cavity of the working box, and the mounting rack is fixedly connected between the upper sides of the front and rear side walls of the mounting rack. Among them, a first motor is fixedly connected to the right side of the front side wall of the working box, a worm is fixedly connected to the power output end of the first motor, a bidirectional screw rod is rotatably connected between the top and bottom of the inner cavity of the connecting groove, and movable blocks are threadedly connected to both the upper and lower sides of the outer side wall of the bidirectional screw rod. A support groove is opened on the left side of the front side wall of the front movable block, and a rotating rod is rotatably connected to the inner side wall of the support groove through a bearing; it can facilitate the removal of the moisture on the surface of the nylon filaments first and then dry the nylon filaments, reducing the drying time of the nylon filaments and improving the working efficiency of the drying equipment. It solves the problem that when the existing nylon filament processing and drying equipment is in use, it usually uses a blower and a heating plate to dry the nylon filaments with hot air. When there is a lot of moisture on the surface of the nylon filaments, it is not convenient to first remove the moisture on the surface of the nylon filaments and then dry the nylon filaments, increasing the drying time of the nylon filaments and reducing the working efficiency of the drying equipment.

[0004] It is found through research that when the above patent is actually applied, multiple electrical actuating elements (motors) need to be set to provide drive. At the same time, the driving force provided for the extrusion rollers is carried out by the motor in cooperation with the worm and the worm gear. The transmission ratio of the worm and the worm gear is relatively large, and the conveying efficiency of the nylon filaments is relatively low. And when the distance between the two extrusion rollers changes, the worm will disengage from the worm gear, resulting in the situation where effective transmission cannot be achieved.

[0005] Therefore, in order to solve the above deficiencies and further improve the drying efficiency of nylon filaments and reduce the energy consumption of the drying operation, the utility model proposes a nylon filament drying device.

The installation box 5 is fixedly installed at the bottom of the box body 1. A first rectangular frame 52 and a second rectangular frame 54 are fixedly installed on the inner wall of the box body 1. Both the first rectangular frame 52 and the second rectangular frame 54 are hollow. Through holes communicating with the box body 1 are formed on the inner walls of the first rectangular frame 52 and the second rectangular frame 54. A heating and cooling fan 51 is fixedly installed on the top inner wall of the installation box 5. The air outlet of the heating and cooling fan 51 is communicated with the first rectangular frame 52. A same conveying pipe 53 is connected between the second rectangular frame 54 and the installation box 5, and the second rectangular frame 54 and the installation box 5 are communicated through the conveying pipe 53, which can dry the nylon filament passing through the first rectangular frame 52 and the second rectangular frame 54, and can realize the recycling of heat, thereby reducing the energy consumption during the drying operation. A plurality of clamping interfaces are formed on the bottom inner wall of the installation box 5. A dehumidification filter plate 55 is clamped and installed in each of the plurality of clamping interfaces. The dehumidification filter plate 55 is in movable sealing contact with the inner wall of the installation box 5.The bottom sides of multiple dehumidification filter plates 55 all extend below the installation box 5 and are fixedly installed with the same installation plate 56. A handle is fixedly installed on the bottom side of the installation plate 56, which can dehumidify the hot air flowing back in the box body 1, thereby further improving the drying efficiency of the nylon filaments.

[0041] Specifically, in order to reduce the amount of hot air flowing towards the pressing roller 3 and at the same time prevent the water discharged by the extrusion of the pressing roller 3 from entering the position of the first rectangular frame 52, two partition plates 13 located in the same vertical plane are fixedly installed on the inner wall of the box body 1.

[0042] Specifically, in order to prevent the nylon filaments from being scratched or broken when coming into contact with the partition plates 13, the mutually approaching sides of the two partition plates 13 are both provided with rounded corners.

[0043] Specifically, in order to divert the water discharged by the extrusion of the pressing roller 3 and at the same time facilitate the collection and discharge of the water discharged from the box body 1, a diversion plate is fixedly installed on the bottom inner wall of the box body 1. The diversion plate is located below the pressing roller 3. A water collection tank 6 communicated with the box body 1 is fixedly installed at the bottom of the box body 1, and a drain pipe provided with a control valve is fixedly installed on the water collection tank 6.

[0044] Regarding the motors, cooling and heating fans involved, as well as the required circuits, electronic components and module mechanisms, etc., existing technologies are adopted. Those skilled in the art can fully implement them without further elaboration. The content protected by this application does not involve improvements to software, circuits and methods either.

[0045] Working principle: First, connect the power supply and pass the nylon filaments through the two strip-shaped openings on the box body 1 to penetrate the entire box body 1 and keep them entering from the left and exiting from the right. At the same time, make them pass between the upper roller 11 and the lower roller 12 and between the two pressing rollers 3, and pass through the first rectangular frame 52 and the second rectangular frame 54. With the cooperation of the upper roller 11 and the lower roller 12, it can ensure that the nylon filaments can be stably guided when entering and exiting the box body 1. Inside the box body 1, the nylon filaments are clamped by the two pressing rollers 3. These two pressing rollers 3 can maintain a stable pressure through the cooperation of the support shafts 31, the guide blocks 2 and the tension springs 22. At the same time, the motor 44 can drive the two support shafts 31 to rotate synchronously and reversely through the transmission of the second gear 43 and the first gear 4, so that the two pressing rollers 3 also rotate synchronously and reversely, ensuring that the redundant water is extruded when the nylon filaments pass through, and at the same time ensuring that there is no sliding during the drying process. The water discharged by the extrusion of the pressing roller 3 is diverted into the water collection tank 6 under the action of the diversion plate.

[0046] Since the two second gears 43 always remain in a meshed state, and the two second gears 43 are respectively meshed with the corresponding first gears 4, when the output shaft of the motor 44 drives one of the second gears 43 to rotate, the driving of the two support shafts 31 can be achieved and they can maintain stable synchronous reverse rotation. With the cooperation of the first support plate 41 and the second support plate 42, even if the distance between the two guide blocks 2 in the guide port 102 changes, it will not affect the synchronous reverse rotation of the support shafts 31.

[0047] The heating and cooling fan 51 sends hot air into the first rectangular frame 52, and the hot air circulates through the second rectangular frame 54 and the delivery pipe 53 to dry the nylon filaments. At the same time, the heat can also be recycled and reused, effectively reducing the energy consumption during the drying process.

[0048] The dehumidification filter plate 55 at the bottom of the installation box 5 dehumidifies the hot air flowing back into the box body 1, which can further improve the drying efficiency. The setting of the partition plate 13 reduces the amount of hot air flowing towards the pressing roller 3, and at the same time prevents the water discharged by the extrusion of the pressing roller 3 from entering the position of the first rectangular frame 52. At the same time, the rounded corner design of the partition plate 13 ensures that the nylon filaments will not be scratched or broken when coming into contact with it.

[0049] The above has introduced in detail a nylon filament drying device provided by the present utility model. Specific embodiments are used in this article to elaborate on the principle and implementation manner of the present utility model. The description of the above embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
