Description

Technical Field

[0001] This invention relates to the field of textile yarn drying technology, and in particular to a drying equipment for textile yarn production. Background Technology

[0002] Drying textile yarns is a crucial part of the entire production process. Its purpose is to remove moisture efficiently and evenly while ensuring the physical properties and appearance quality of the yarns. Currently, hot air dryers are mainly used for drying.

[0003] In existing hot air dryers, the yarn is dried by passing through a drying chamber under the action of rollers. Inside the drying chamber, hot air at a certain speed and pressure carries away the moisture from the yarn, thus achieving the drying effect.

[0004] However, existing hot air dryers for yarn drying still have the following shortcomings: Although existing hot air dryers can dry yarn by continuously generating hot air, they are only effective for sparse yarns. For yarn sheets composed of parallel, tightly arranged yarns, the drying effect is generally poor, and the drying efficiency is not high enough. This is because the yarns in the yarn sheet are piled up, making it difficult for hot air to pass through effectively, resulting in deep moisture not being easily dissipated, much like thick hair, which is difficult to dry quickly from the surface with hot air. Although some existing drying equipment also uses combing devices to comb and disperse the piled-up yarns, or guides the yarns to disperse using guide plates with dispersion holes, allowing hot air to easily pass through the gaps between the yarns, the effect and method of such treatment are relatively simple, and the efficiency is generally low. It is still difficult to quickly and effectively dry and remove the deep moisture inside the yarn, resulting in generally low overall drying efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a drying equipment for textile yarn production, so as to solve the technical problem that the hot air dryer used in the existing yarn drying equipment has a single working mode and general drying efficiency.

[0006] The technical problem to be solved by this invention can be achieved through the following technical solution: A drying treatment device for textile yarn production includes a support platform, a drying chamber, and conveying rollers for conveying yarn layers, and further includes: The distributing mechanism is suspended at the top of the drying chamber and includes an arc-shaped swing plate for distributing the yarn layer. A lifting and pressing nozzle mechanism is installed at the bottom of the drying chamber and is used to blow hot air onto the yarn layer and intermittently press the yarn layer from bottom to top.

[0007] Preferably, the sorting mechanism further includes a drive shaft, which is rotatably connected to the inner top of the drying chamber; the arc-shaped swing plate is disposed on the drive shaft, and the convex arc surface of the arc-shaped swing plate presses down on the yarn layer, and the drive shaft drives the arc-shaped swing plate to swing back and forth.

[0008] Preferably, the convex arc surface of the arc-shaped swing plate is provided with wave grooves.

[0009] Preferably, electric telescopic rods are vertically fixedly connected to both ends of the drive shaft, and the arc-shaped swing plate is fixedly connected to the telescopic end of the electric telescopic rod.

[0010] Preferably, both sides of the drying box are horizontally rotatably connected to transition rollers, and the position of the transition rollers is higher than the position of the arc swing plate.

[0011] Preferably, the lifting top pressure nozzle mechanism includes an arc-shaped top pressure plate, a spray pipe, and a linkage lifting mechanism. The concave arc surface of the arc-shaped top pressure plate faces upward. The spray pipe is disposed on the arc-shaped top pressure plate. The spray pipe is used to spray hot air upward. The arc-shaped top pressure plate is connected to the inside of the drying chamber through the linkage lifting mechanism, and the arc-shaped swing plate drives the arc-shaped top pressure plate to rise and fall through the linkage lifting mechanism.

[0012] Preferably, the linkage lifting mechanism includes a connecting guide rail and a linkage baffle. The connecting guide rail is vertically fixed to the inner top of the drying chamber; the linkage baffle is also slidably connected to the connecting guide rail; the linkage baffle is fixedly connected to the end of the arc-shaped top pressure plate, and the linkage baffle is aligned with the end of the arc-shaped swing plate.

[0013] Preferably, the lifting and lowering top pressure nozzle mechanism further includes a linkage return mechanism for driving the nozzle to reciprocate; the linkage return mechanism includes a mounting through hole, a linkage horizontal plate, a movable connecting piece, and a transverse pressing piece; the mounting through hole is formed on the arc-shaped top pressure plate; the nozzle is rotatably connected in the mounting through hole; a guide sleeve is fixedly connected below the arc-shaped top pressure plate, the linkage horizontal plate slides laterally through the guide sleeve, and a limit spring is also connected between the linkage horizontal plate and the guide sleeve; the nozzle is movably connected to the linkage horizontal plate through the movable connecting piece; the transverse pressing piece is fitted between the linkage horizontal plate and the inner wall of the drying chamber, and the transverse pressing piece is used to laterally push the linkage horizontal plate.

[0014] Preferably, the transverse extrusion component includes a spherical extrusion rod assembly and a conical end; two conical ends are provided and symmetrically fixedly connected to both ends of the linkage cross plate; two sets of spherical extrusion rod assemblies are provided and respectively fixedly connected to the inner walls of both sides of the drying oven; the two sets of spherical extrusion rod assemblies are longitudinally staggered and the spherical extrusion rod assemblies are correspondingly matched with the conical ends.

[0015] Preferably, the movable connector includes a strip-shaped guide hole and a linkage post; the strip-shaped guide hole is vertically opened on the linkage horizontal plate; the linkage post is vertically connected to the outer wall of the bottom of the nozzle, and the linkage post moves through the strip-shaped guide hole.

[0016] The beneficial effects of this invention are: 1. This invention effectively disperses the yarn layer passing through the drying chamber by using an arc-shaped swing plate, thereby facilitating the effective passage of hot air generated by the lifting top pressure nozzle mechanism through the yarn layer for drying. At the same time, while blowing hot air from bottom to top, the lifting top pressure nozzle mechanism also continuously squeezes the yarn layer upwards, causing the moisture inside the yarn layer to be squeezed out. Through the simultaneous action of multiple mechanisms, it is beneficial to improve the overall drying efficiency.

[0017] 2. The circular arc swing plate of the present invention relies on the convex arc surface to squeeze the yarn layer passing through downward, so that the yarn layer is effectively dispersed. At the same time, the drive shaft drives the circular arc swing plate to swing back and forth, thereby moving the yarn layer and further promoting the dispersion of the yarn layer, so that hot air can pass through the gaps between the yarns, which is beneficial to drying.

[0018] 3. In the present invention, the arc-shaped swing plate continuously squeezes the linkage baffle during the swing process. The linkage baffle slides up and down along the connecting guide rail, thereby driving the arc-shaped top pressure plate to move and rise synchronously. The arc-shaped top pressure plate presses against the yarn layer, squeezing out the moisture inside.

[0019] 4. During the upward compression of the yarn layer by the arc-shaped top pressure plate of this invention, the linkage horizontal plate set below the arc-shaped top plate compresses the yarn layer by means of the conical end and the fixed spherical compression rod group. With the help of the rebound force of the limit spring, the linkage horizontal plate can slide back and forth laterally. During the lateral back and forth sliding of the linkage horizontal plate, the nozzle is driven to swing back and forth by the movement of the strip guide hole and the linkage column, which facilitates the generation of vortex airflow or airflow in multiple directions. This is conducive to the hot air entering the deep layer of the compressed yarn. At the same time, the swing can also increase the coverage area of ​​the hot air, thereby effectively ensuring the drying effect. When the arc-shaped top pressure plate is lowered and reset, the nozzle rotates to the vertical position and can spray hot air vertically into the yarn layer, effectively impacting and removing the saturated moisture squeezed out of the yarn layer.

[0022] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0023] like Figures 1-9As shown, a drying device for textile yarn production is used to dry yarn sheets, which are a layer of parallel and tightly arranged yarns. The device includes a support platform 1, conveyor rollers 2, and a drying chamber 3. Two conveyor rollers 2 are provided, rotatably mounted on opposite sides of the support platform 1 via shaft brackets. The conveyor rollers 2 are used to mount yarn bobbins; one conveyor roller 2 is for feeding yarn, and the other is for winding yarn. The winding conveyor roller 2 is driven to rotate by a motor. Both conveyor rollers 2 have threaded fastening rings at their ends. After the yarn bobbin is mounted on the conveyor roller 2, the fastening rings are screwed on and secured. The drying chamber 3 is positioned between the two conveyor rollers 2 and extends laterally through the support platform 1. A hot air blower 7 is installed below the support platform 1. The hot air blower 7 is used to deliver hot air into the drying chamber 3 from bottom to top. The hot air blower 7 includes a blower and an electric heating element installed at the blower's air outlet. The electric heating element generates heat when energized, heating the airflow generated and delivered by the blower. An air outlet duct 31 is installed on the top of the drying chamber 3. The air outlet duct 31 can be connected to an external dehumidification system, or a delivery pump can be installed on the air outlet duct 31 to assist in drawing out the humid airflow discharged from the air outlet duct 31 and transferring it to the dehumidification system for dehumidification treatment. Then, it is circulated back to the air inlet of the hot air blower 7 or delivered to other equipment that needs to use heat, making full use of the thermal energy of the hot air. The yarn layer 8 passes through the drying chamber 3, making it easy to be heated and dried by the hot air blown from bottom to top. The equipment also includes a distribution mechanism 5 and a lifting top pressure nozzle mechanism 6. The distribution mechanism 5 is suspended at the top inside the drying chamber 3 and includes an arc-shaped swing plate 51 for dispersing the yarn layer 8 passing through the drying chamber 3, which facilitates the dispersion of the yarn in the yarn layer 8, which is beneficial for drying and prevents the deep yarn from failing to effectively contact the hot air to complete the drying process. The lifting top pressure nozzle mechanism 6 is installed at the bottom inside the drying chamber 3 and is connected to the air outlet of the hot air blower 7 through a pipe. The lifting top pressure nozzle mechanism 6 is used to blow hot air onto the yarn layer 8 and intermittently press the yarn layer 8 from bottom to top. Since the distribution mechanism 5 is suspended at the top inside the drying chamber 3, it provides support or downward pressure to the yarn layer 8 from top to bottom. This allows the top pressure nozzle mechanism 6 to continuously squeeze the yarn layer 8 while blowing hot air, causing the moisture inside the yarn layer 8 to be squeezed outward, breaking the surface tension of the water, reducing the energy required for evaporation, and thus improving the drying efficiency.

[0024] In some specific implementation schemes, refer to Figure 2 and Figure 3As shown, the sorting mechanism 5 also includes a drive shaft 52, which is rotatably connected to the top of the drying chamber 3 via a shaft bracket, and the drive shaft 52 is parallel to the conveying direction of the yarn layer 8; two arc-shaped swing plates 51 are provided and distributed at both ends of the drive shaft 52, and the convex arc surface of the arc-shaped swing plate 51 presses down on the yarn layer 8. When the yarn layer 8 passes through the drying chamber 3, it contacts the bottom of the arc-shaped swing plate 51, and the drive shaft 52 drives the arc-shaped swing plate 51 to swing back and forth.

[0025] It should be noted that, in order to facilitate the forward and reverse rotation of the drive shaft 52, a servo motor is fixedly installed on the top outer side of the drying oven 3, and a transmission wheel is coaxially fixed at the main shaft end of the servo motor and the end of the drive shaft 52 on the same side. The two transmission wheels are connected by a transmission belt, which facilitates the back-and-forth swing drive.

[0026] The raised arc surface of the arc swing plate 51 facilitates the dispersion of the yarn in the yarn layer 8. At the same time, the drive shaft 52 drives the arc swing plate 51 to swing back and forth, which facilitates further dispersion of the yarn and can also cause the yarn to shake, accelerating moisture loss.

[0027] In a further specific implementation, the convex arc surface of the arc swing plate 51 is provided with wave grooves 53. The wave grooves 53 are used to further disperse the contacting yarn layers 8, and at the same time, due to the existence of concave and convex positions, it is convenient to move the yarn layers 8.

[0028] In some specific implementations, in order to facilitate the control of the pressure of the arc swing plate 51 on the passing yarn layer 8, electric telescopic rods 54 are vertically fixedly connected to both ends of the drive shaft 52. The telescopic ends of the electric telescopic rods 54 face downwards, and the arc swing plate 51 is fixedly connected to the telescopic ends of the electric telescopic rods 54.

[0029] In addition, to prevent the yarn layer 8 from sagging and failing to be effectively positioned below the arc-shaped swing plate 51, both sides of the drying chamber 3 are connected to the transition roller shaft 4 via a horizontally rotating shaft frame, and the position of the transition roller shaft 4 is higher than that of the arc-shaped swing plate 51.

[0030] This allows the yarn layer 8 to pass over the transition roller shaft 4 on one side, supported by the transition roller shaft 4, and then pass through the bottom of the arc swing plate 51, and finally pass over the transition roller shaft 4 on the other side. In conjunction with the electric telescopic rod 54 driving the arc swing plate 51 to press down, it is easy to keep the yarn layer 8 at a certain tension.

[0031] It should be noted that an opening can be made on one side of the drying oven 3 to facilitate the insertion and insertion of the yarn layer 8.

[0032] In some specific implementation plans, combined with Figure 2 and Figure 4As shown, the lifting top pressure nozzle mechanism 6 includes an arc-shaped top pressure plate 61, a nozzle 64, and a linkage lifting mechanism. The concave arc surface of the arc-shaped top pressure plate 61 faces upward, and the arc radius of the arc-shaped top pressure plate 61 is equal to the arc radius of the arc-shaped swing plate 51, which facilitates the effective compression of the yarn layer 8 distributed on the arc surface formed by the compression of the arc-shaped swing plate 51 when moving upward. Multiple nozzles 64 are provided and are distributed laterally on the arc-shaped top pressure plate 61. Each nozzle 64 is connected to the main air outlet pipe of the hot air blower 7 through a metal corrugated hose for spraying hot air upward. The arc-shaped top pressure plate 61 is connected to the inside of the drying chamber 3 through the linkage lifting mechanism, and the arc-shaped swing plate 51 drives the arc-shaped top pressure plate 61 to rise and fall through the linkage lifting mechanism.

[0033] The linkage lifting mechanism includes connecting guide rails 63 and linkage baffles 62. Two connecting guide rails 63 are symmetrically arranged and vertically fixed to the inner top sides of the drying chamber 3, specifically distributed on both sides of the arc swing plate 51. Two linkage baffles 62 are also provided and are slidably connected to the corresponding connecting guide rails 63. The linkage baffles 62 are fixedly connected to the end of the arc top pressure plate 61 through a bracket, and the linkage baffles 62 are aligned with the end of the arc swing plate 51, with the end of the arc swing plate 51 located below the linkage baffles 62.

[0034] During the swinging process of the arc swing plate 51, when the arc swing plate 51 swings to one side, it squeezes and pushes the linkage baffle 62, causing the linkage baffle 62 to slide upward along the connecting guide rail 63. In this way, the linkage baffle 62 drives the arc top pressure plate 61 to rise. The arc top pressure plate 61 sprays hot air to the yarn layer 8 through the nozzle 64 to dry it, and squeezes the yarn layer 8 from bottom to top to squeeze out the moisture inside and accelerate the drying effect.

[0035] In some specific implementation schemes, when the arc-shaped top pressure plate 61 presses upwards, it easily leads to an increase in the yarn distribution density of the yarn layer 8 and a smaller fiber gap, resulting in increased resistance to the passage of hot air vertically sprayed towards the location of the yarn layer 8, which is not conducive to drying. Therefore, in order to further improve the drying effect, combined with Figure 2 as well as Figures 4 to 6 As shown, the lifting and pressing nozzle mechanism 6 also includes a linkage swing mechanism 65 for driving the nozzle 64 to swing back and forth.

[0036] The linkage swing mechanism 65 includes a mounting through hole 655, a linkage horizontal plate 652, a movable connecting piece, and a transverse pressing piece. The mounting through hole 655 is opened on the arc-shaped top pressure plate 61, and multiple mounting through holes 655 are simultaneously set when multiple nozzles 64 are set. The nozzles 64 are vertically set in the mounting through hole 655, and the nozzles 64 are rotatably connected to the inner wall of the mounting through hole 655 through a rotating shaft. The distribution direction of the rotating shaft connected here is parallel to the conveying direction of the yarn layer 8, and the mounting through hole 655 has a sufficiently large space for the nozzles 64 to rotate at a certain angle. The swing range is within the range; a guide sleeve 654 is fixedly connected to the bottom of the arc-shaped top pressure plate 61 by a bracket. One guide sleeve 654 can be set on each side. The linkage horizontal plate 652 slides laterally through the guide sleeve 654. A limit spring 656 is also connected between the linkage horizontal plate 652 and the guide sleeve 654. The limit spring 656 can be compressed and stretched. The nozzle 64 is movably connected to the linkage horizontal plate 652 through a movable connector. A transverse extrusion member is set between the linkage horizontal plate 652 and the inner wall of the drying box 3. The transverse extrusion member is used to continuously push the linkage horizontal plate 652 laterally.

[0037] The transverse extrusion component includes a spherical extrusion rod assembly 651 and a conical end 653. Two conical ends 653 are provided and symmetrically fixedly connected to both ends of the linkage horizontal plate 652. The tips of the conical ends 653 face the inner wall of the drying chamber 3, and the upper and lower surfaces of the conical ends 653 are both inclined surfaces. Two sets of spherical extrusion rod assemblies 651 are provided and fixedly connected to the inner walls of both sides of the drying chamber 3, and the two sets of spherical extrusion rod assemblies 651 are longitudinally staggered. Each set of spherical extrusion rod assemblies 651 includes multiple protruding rods with spherical ends. The protruding rods of the spherical extrusion rod assembly 651 are longitudinally aligned and engaged with the inclined surfaces of the corresponding conical ends 653.

[0038] It should be noted that before the arc-shaped top pressure plate 61 rises, it maintains a certain distance from the spherical extrusion rod assembly 651. This allows the nozzle 64 to maintain a vertically upward position and spray hot air during the initial period of the arc-shaped top pressure plate 61's rise, facilitating direct drying of the dispersed yarn layer 8. When the arc-shaped top pressure plate 61 approaches the location of the yarn layer 8, the tapered end 653 at one end of the linkage horizontal plate 652 begins to press against the corresponding spherical extrusion rod assembly 651. The tapered end 653 is subjected to a lateral force due to the pressure action between the inclined surface and the spherical end of the protruding rod, causing the tapered end 653 to be subjected to a lateral force, which in turn causes the linkage horizontal plate 652 to move laterally to the other side. As the horizontal plate 652 slides, it drives the nozzle 64 to swing to one side via the movable connector. Due to the staggered distribution of the spherical extrusion rods 651 on both sides, after the horizontal plate 652 extrudes the spherical extrusion rods 651 on one side, it extrudes the spherical extrusion rods 651 on the other side as it continues to rise. This facilitates the back-and-forth movement, causing the nozzle 64 to swing back and forth. This allows for multi-angle hot air jetting onto the yarn layer 8 extruded by the arc-shaped top pressure plate 61. The swinging motion also facilitates the formation of vortex airflow, allowing hot air to enter deep areas that traditional vertical airflow cannot reach. At the same time, the swinging motion can also increase the hot air coverage area and improve the overall drying effect.

[0039] It should be noted that the distance between two adjacent protrusions in the spherical extrusion rod assembly 651 is greater than twice the longitudinal width of the conical end 653. At the same time, the misalignment distance between the two spherical extrusion rod assemblies 651 is at least the longitudinal width of the conical end 653, ensuring that the linkage plate 652 can move back and forth.

[0040] Additionally, it should be noted that the top of the nozzle 64 is lower than the upper port of the mounting through hole 655, and the bottom of the nozzle 64 extends from the lower port of the mounting through hole 655, to prevent the nozzle 64 from contacting the yarn layer 8 during its swing.

[0041] In a further specific implementation plan, refer to Figure 6 As shown, the movable connector includes a strip-shaped guide hole 657 and a linkage post 658. The strip-shaped guide hole 657 is vertically formed on the linkage horizontal plate 652 and extends horizontally through the linkage horizontal plate 652. The linkage post 658 is vertically connected to the bottom outer wall of the nozzle 64. Here, the linkage post 658 can be rotatably connected to the nozzle 64 or fixedly connected, and the linkage post 658 moves through the strip-shaped guide hole 657. Before the linkage horizontal plate 652 shifts laterally, the linkage post 658 is positioned in the middle of the strip-shaped guide hole 657.

[0042] When the linkage plate 652 moves laterally to one side, it pushes the linkage column 658 through the strip guide hole 657. The linkage column 658 then drives the nozzle 64 to deflect. The linkage column 658 can slide along the strip guide hole 657 to ensure that the nozzle 64 deflects normally.

[0043] It should be noted that the above-mentioned movable connector can also be implemented in other ways. For example, a lever can be directly fixedly connected to the linkage plate 652. The lever is located on the bottom side of the nozzle 64. During the lateral movement of the linkage plate 652, the bottom of the nozzle 64 is deflected by the lever.

[0044] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: First, a yarn bobbin with the yarn wound on it is assembled onto one side of the conveyor roller 2, and an empty yarn bobbin is assembled onto another conveyor roller 2 equipped with a drive motor. Then, the yarn layer 8 on the yarn bobbin with the yarn wound on it is pulled out and passed over the top of the transition roller 4 on one side, supported by the transition roller 4. Then, it passes through the bottom of the arc swing plate 51 and finally passes over the top of the transition roller 4 on the other side. With the help of the electric telescopic rod 54, the arc swing plate 51 is pressed down, so that the yarn layer 8 can maintain a certain tension.

[0045] Then, the hot air blower 7 is started, and the servo motor drives the drive shaft 52 to continuously rotate forward and backward. The arc surface of the arc swing plate 51 presses down, which facilitates the dispersion of the yarn in the yarn layer 8. At the same time, as the drive shaft 52 drives the arc swing plate 51 to swing back and forth, it is easier to further disperse the yarn and promote the shaking of the yarn. Under the synchronous action of the hot air blown from bottom to top, the moisture loss is accelerated.

[0046] During the swinging process of the arc swing plate 51, when the arc swing plate 51 swings to one side, it squeezes and pushes the linkage baffle 62, causing the linkage baffle 62 to slide upward along the connecting guide rail 63. In this way, the linkage baffle 62 drives the arc top pressure plate 61 to rise. The arc top pressure plate 61 sprays hot air to the yarn layer 8 through the nozzle 64 to dry it, and squeezes the yarn layer 8 from bottom to top to squeeze out the moisture inside and accelerate the drying effect.

[0047] Before the arc-shaped top pressure plate 61 rises, it maintains a certain distance from the spherical extrusion rod assembly 651. This allows the nozzle 64 to maintain a vertically upward position and spray hot air during the initial rising period of the arc-shaped top pressure plate 61, facilitating direct drying of the dispersed yarn layer 8. When the arc-shaped top pressure plate 61 approaches the location of the yarn layer 8, the tapered end 653 of one end of the linkage horizontal plate 652 begins to press against the corresponding spherical extrusion rod assembly 651. The tapered end 653 is subjected to a lateral force due to the pressure action between the inclined surface and the spherical end of the protruding rod, causing the tapered end 653 to slide laterally to the other side. During the sliding process, the linkage horizontal plate 652 pushes against the linkage column 658 through the strip guide hole 657, and the linkage column 658 drives the nozzle 651 to dry. 4. The deflection and the sliding of the linkage column 658 along the strip guide hole 657 ensure the normal deflection of the nozzle 64. Due to the staggered distribution of the spherical extrusion rod groups 651 on both sides, after the linkage horizontal plate 652 and the spherical extrusion rod group 651 on one side are squeezed, as it continues to rise, it will squeeze the spherical extrusion rod group 651 on the other side. This facilitates the back-and-forth movement, which makes the nozzle 64 swing back and forth, which facilitates the multi-angle hot air jetting effect on the yarn layer 8 squeezed by the arc top pressure plate 61. The swing also facilitates the formation of vortex airflow, which makes it easier for hot air to enter the deep area that traditional vertical airflow cannot reach. At the same time, the swing can also increase the hot air coverage area, improve the overall drying effect, and avoid the yarn distribution density of the yarn layer 8 increasing and the fiber gaps becoming smaller due to the upward squeezing of the arc top pressure plate 61, which is not conducive to drying.

[0048] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
