Description

[0002] In the textile production process, the drawing process plays an extremely critical role. It can improve the internal structure of the sliver, improve the uniformity of the sliver and the straight parallelism of the fiber. The temperature and humidity of the working environment of the drawing machine have a significant impact on the quality of the sliver. Under conditions of too high or too low temperature and humidity, the physical properties of the fiber will change.

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0023] Embodiment 1: like Figures 1 to 9 As shown, a temperature and humidity adjustment system for a drawing frame includes an industrial air conditioner 1, an air outlet cover 2, a bottom plate 4, a pair of positioning rings 3, a sealing cover 5, an insertion rod 6 and a sleeve ring 7.

[0024] The inner cavity of the air outlet hood 2 is connected to the air outlet of the industrial air conditioner 1; the industrial air conditioner is a prior art, so its working principle is not described here in detail.

[0025] The bottom plate 4 is rotatably mounted on the bottom of the air outlet cover 2, a plurality of pairs of positioning sleeves 41 are mounted on the bottom plate 4, and an air inlet 411 is opened on the air outlet cover 2; A pair of positioning rings 3 is placed in the inner cavity of the air outlet cover 2, a driving motor 35 is installed on the bottom plate 4, a synchronous shaft 341 is rotatably installed on the bottom plate 4, a half gear 34 is installed on the synchronous shaft 341, the half gear 34 is placed in the gap between the pair of positioning rings 3, and the positioning rings 3 are vertically distributed, and a plurality of pairs of first racks 32 are installed on the positioning ring 3 located at the bottom, and a plurality of pairs of second racks 33 are installed on the positioning ring 3 located at the top, each pair of first racks 32 and second racks 33 correspond to each other in an alternating manner, and a gap is left between adjacent first racks 32 and second racks 33, the first racks 32 and the second racks 33 are adapted to each other with the half gear 34, a torsion spring 342 is clamped on the synchronous shaft 341, a rocker 36 is installed on the synchronous shaft 341, a synchronous plate 37 is slidably provided on the side wall of the rocker 36, and the synchronous plate 37 corresponds vertically to the positioning sleeve 41; The sealing cover 5 is slidably disposed in the inner cavity of the positioning sleeve 41, the bottom of the sealing cover 5 is connected to a connecting pipe 52, and the end of the connecting pipe 52 is installed with a nozzle 521; The insertion rod 6 movably passes through the positioning sleeve 41, one end of the insertion rod 6 is connected to the sealing cover 5, and the other end of the insertion rod 6 is connected to the bottom of the synchronization plate 37; The driving motor 35 can drive the base plate 4 to rotate. At this time, the positioning sleeve 41 on the base plate 4 can drive the sealing cover 5 to rotate, and the connecting pipe 52 at the bottom of the sealing cover 5 can drive the nozzle 521 to rotate, so that the nozzle 521 as a whole rotates with the base plate 4, and the position where the nozzle 521 sprays changes, ensuring that the sprayed gas can be evenly distributed in the inner cavity of the drawing frame, ensuring that the drawing frame has relatively uniform temperature and humidity. When the half gear 34 follows the rotation of the bottom plate 4, after the half gear 34 contacts the first rack 32, the half gear 34 rotates to a certain angle, and when the half gear 34 separates from the first rack 32, the half gear 34 resets. When the half gear 34 contacts the second rack 33, the half gear 34 rotates in the opposite direction by a certain angle and resets later. Then, the half gear 34 can rotate back and forth periodically, thereby driving the seesaw 36 to rotate. One side of the seesaw 36 can squeeze the insertion rod 6 and the sealing cover 5 to move downward, thereby moving the nozzle 521 downward, and the other side of the seesaw 36 can drive the nozzle 521 to move upward, store and close the nozzle 521. Through the reciprocating rotation of the seesaw 36, it is ensured that only one side of the nozzle 521 is open, thereby increasing the flow rate of the gas at the injection point of the nozzle 521, allowing the gas to flow to a farther position, thereby ensuring that the temperature and humidity can be regulated more evenly.

[0026] The collar 7 slides on the side wall of the connecting tube 52, and a push rod 71 is rotatably installed on the side wall of the collar 7. The push rod 71 slides horizontally under the sealing cover 5. A plurality of pairs of protrusions 72 are installed on the positioning sleeve 41. The plurality of pairs of protrusions 72 are spirally distributed. Spiral grooves 721 are provided on the plurality of pairs of protrusions 72 and the side wall of the positioning sleeve 41. A downward groove 722 is connected at the end of the spiral groove 721, and the downward groove 722 is slidably connected to the push rod 71. When the push rod 71 and the sealing cover 5 move downward, the side wall of the push rod 71 can move along the spiral groove 721 on the surface of the protrusion 72, so the push rod 71 and the connecting pipe 52 drive the nozzle 521 to rotate, and the spiral groove 721 is provided with a protrusion 72, which squeezes the push rod 71 to move toward the connecting pipe 52. The angle of the connecting pipe 52 changes due to the squeezing of the push rod 71. The position of the nozzle 521 connected to the connecting pipe 52 is constantly changing, and it can spray in different directions to ensure that the temperature and humidity in the drawing machine become more uniform.

[0027] like Figures 1 to 9 As shown, in a specific embodiment, a support frame 12 is installed at the bottom of the industrial air conditioner 1, a positioning hole is opened on the support frame 12, an air supply duct 11 is installed on the air outlet of the industrial air conditioner 1, a cover plate 21 is installed on the air outlet cover 2, a connection port 211 is opened on the cover plate 21, and the end of the connection port 211 is connected to the end of the air supply duct 11.

[0028] like Figures 1 to 9 As shown, further, a connecting seat 31 is installed on the positioning ring 3, and a positioning rod 311 is installed on the side wall of the connecting seat 31. The end of the positioning rod 311 is interconnected with the side wall of the air outlet cover 2. The connecting seat 31 and the positioning rod 311 limit the installation position of the positioning ring 3.

[0029] Embodiment 2: The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, a fixed seat 344 is installed on the base plate 4, a rotating shaft 351 is installed on the fixed seat 344, the end of the rotating shaft 351 is connected to the output end of the driving motor 35, a synchronous seat 343 is installed on the base plate 4, the synchronous shaft 341 movably passes through the synchronous seat 343, the end of the synchronous shaft 341 is connected to the fixed seat 344, and a torsion spring 342 is sleeved on the side wall of the synchronous shaft 341, one end of the torsion spring 342 is clamped on the synchronous seat 343, and the other end is clamped on the half gear 34. When the half gear 34 first meshes with the first rack 32, as the meshing continues, the half gear 34 will drive the synchronization shaft 341 to rotate a certain angle, and the torsion spring 342 is torsion-acted synchronously at this time. When the half gear 34 and the first rack 32 are separated, the torsion spring 342 drives the half gear 34 to reset. After continuing to move for a distance, the half gear 34 and the second rack 33 are meshed at this time, and then the half gear 34 drives the synchronization shaft 341 to rotate in the opposite direction by a certain angle. The half gear 34 is continuously meshed with the first rack 32 and the second rack 33, driving the half gear 34 and the synchronization shaft 341 to rotate back and forth periodically.

[0030] like Figures 1 to 9 As shown, in a specific embodiment, a strip groove 361 is provided on the seesaw 36, and the extension line of the strip groove 361 intersects with the synchronization shaft 341. A vertical plate 371 is installed on the synchronization plate 37, and a sliding rod 372 is installed on the side wall of the vertical plate 371. The sliding rod 372 is slidably arranged on the strip groove 361. During the rotation of the seesaw 36, the sliding rod 372 on the seesaw 36 slides in the strip groove 361, thereby driving the vertical plate 371 and the synchronization plate 37 to slide, and the synchronization plate 37 can move downward through the insertion rod 6 and the sealing cover 5, and the nozzle 521 at the bottom of the sealing cover 5 can move downward synchronously.

[0031] like Figures 1 to 9As shown, further, the positioning sleeve 41 is provided with an air inlet chamber 412 and a displacement chamber 413, respectively, the air inlet chamber 412 and the displacement chamber 413 are blocked by the sealing cover 5, the air inlet chamber 412 and the internal dimensions of the sealing cover 5 are adapted to each other, the air inlet 411 and the air inlet chamber 412 are connected to each other, and the connecting pipe 52 is placed inside the displacement chamber 413. When the sealing cover 5 moves downward, the side wall of the sealing cover 5 can slide inside the air inlet chamber 412, and when the air inlet 411 is not blocked by the sealing cover 5, the gas inside the air outlet cover 2 enters the sealing cover 5 through the air inlet 411, and is conveniently sprayed out from the nozzle 521 later through the connecting pipe 52.

[0032] Embodiment 3: The difference between the above embodiment and this embodiment is that: Figures 1 to 9 As shown, the air inlet chamber 412 is interconnected with the internal chamber of the sealing cover 5, a hose 511 is installed at the bottom of the sealing cover 5, and the end of the hose 511 is connected to the connecting pipe 52. A base 53 is installed at the bottom of the sealing cover 5, and a card shaft 531 is rotatably installed inside the base 53, and the end of the card shaft 531 is rotatably connected to the side wall of the connecting pipe 52.

[0033] like Figures 1 to 9 As shown, in a specific embodiment, a cross connecting plate 51 is installed on the sealing cover 5, and the cross connecting plate 51 is rotatably connected to the plug rod 6. A limit plate 62 is installed at the end of the plug rod 6, and the surface of the limit plate 62 is in contact with the side wall of the vertical plate 371. A return spring 61 is installed on the plug rod 6, and one end of the return spring 61 is clamped on the side wall of the positioning sleeve 41, and the other end of the return spring 61 is clamped on the bottom of the limit plate 62. When the sealing cover 5 moves, the plug rod 6 on the sealing cover 5 moves downward synchronously, the limit plate 62 on the top of the plug rod 6 slides downward, and the return spring 61 at the bottom of the limit plate 62 is compressed, and the return spring 61 is used to facilitate the reset operation later.

[0034] like Figures 1 to 9 As shown, further, a guide rod 711 is installed at the end of the top rod 71, and the guide rod 711 is slidably set in the downward groove 722, and the downward groove 722 is a vertical slide groove. A limit seat 732 is installed at the bottom of the sealing cover 5, and a limit rod 731 is installed on the limit seat 732. A slide plate 73 is slidably set on the limit rod 731. The bottom of the slide plate 73 is connected to the side wall of the top rod 71. A limit spring 733 is sleeved on the limit rod 731. One end of the limit spring 733 is clamped on the limit seat 732, and the other end is clamped on the slide plate 73. When the top rod 71 moves, the slide plate 73 on the top rod 71 slides on the limit rod 731, and the distance between the slide plate 73 and the limit seat 732 becomes closer, and then the limit spring 733 between the two is compressed at this time, and the limit spring 733 is convenient for the later reset operation.

[0035] The implementation principle of a temperature and humidity adjustment system for a drawing frame of this embodiment is as follows: When the temperature and humidity need to be regulated, the operator needs to start the industrial air conditioner 1 , which will deliver the regulated air from the air supply duct 11 and finally enter the inner cavity of the air outlet hood 2 through the connection port 211 on the cover plate 21 .

[0036] At the same time, the operator needs to start the drive motor 35, the drive motor 35 can drive the rotating shaft 351 to rotate, and the rotating shaft 351 synchronously drives the fixed seat 344 to rotate, and the fixed seat 344 is connected to the bottom plate 4, so that the bottom plate 4 can rotate synchronously at this time, and the positioning sleeve 41 on the bottom plate 4 can drive the sealing cover 5 to rotate, and the connecting pipe 52 at the bottom of the sealing cover 5 can drive the nozzle 521 to rotate, so that the nozzle 521 as a whole rotates with the bottom plate 4, and the position of the nozzle 521 is changed, so as to ensure that the injected gas can be evenly distributed in the inner cavity of the drawing frame, so as to ensure that the drawing frame has relatively uniform temperature and humidity.

[0037] The base plate 4 is connected to a synchronization shaft 341 via a synchronization seat 343 . The synchronization shaft 341 is connected to a half gear 34 . The half gear 34 rotates synchronously with the base plate 4 . The half gear 34 rotates in the gap between the two positioning rings 3 .

[0038] When the half gear 34 first meshes with the first rack 32, as the meshing continues, the half gear 34 will drive the synchronization shaft 341 to rotate a certain angle, and the torsion spring 342 is torsion-acted synchronously at this time. When the half gear 34 and the first rack 32 are separated, the torsion spring 342 drives the half gear 34 to reset. After continuing to move for a distance, the half gear 34 and the second rack 33 are meshed at this time, and then the half gear 34 drives the synchronization shaft 341 to rotate in the opposite direction by a certain angle. The half gear 34 is continuously meshed with the first rack 32 and the second rack 33, driving the half gear 34 and the synchronization shaft 341 to rotate back and forth periodically.

[0039] At this time, the seesaw 36 on the half gear 34 rotates synchronously, and the slide bar 372 on the seesaw 36 slides in the strip groove 361, thereby driving the vertical plate 371 and the synchronous plate 37 to slide. The synchronous plate 37 can move downward through the insertion rod 6 and the sealing cover 5, and the nozzle 521 at the bottom of the sealing cover 5 can move downward synchronously.

[0040] When one side of the seesaw 36 can squeeze the insertion rod 6 and the sealing cover 5 to move downward, thereby moving the nozzle 521 downward, the other side of the seesaw 36 can drive the nozzle 521 to move upward, store the nozzle 521, and block the air inlet 411 to close the nozzle 521 on this side. Through the reciprocating rotation of the seesaw 36, it is ensured that only one side of the nozzles 521 on both sides is open, and the gas inside the air outlet hood 2 can only be sprayed out along the nozzle 521 on one side, thereby increasing the flow rate of the gas at the injection point of the nozzle 521, allowing the gas to flow to a farther position, and ensuring that the temperature and humidity can be regulated more evenly.

[0041] When the sealing cover 5 moves downward, the side wall of the sealing cover 5 can slide inside the air inlet chamber 412. When the air inlet 411 is not blocked by the sealing cover 5, the gas inside the air outlet cover 2 enters the sealing cover 5 through the air inlet 411, and is conveniently sprayed out from the nozzle 521 later through the connecting pipe 52.

[0042] When the sealing cover 5 moves, the insertion rod 6 on the sealing cover 5 moves downward synchronously, the limit plate 62 on the top of the insertion rod 6 slides downward, and the return spring 61 at the bottom of the limit plate 62 is compressed, so that the return spring 61 is convenient for the subsequent return operation.

[0043] When the sealing cover 5 drives the connecting tube 52 to move downward, the top rod 71 on the side wall of the connecting tube 52 drives the guide rod 711 to slide along the downward groove 722 first, and the connecting tube 52 is in a vertical state at this time, and then the guide rod 711 slides along the spiral groove 721, thereby driving the sealing cover 5, the connecting tube 52 and the nozzle 521 to rotate at this time, so that different directions can be sprayed, and the spiral groove 721 is provided with a protrusion 72. Whenever the guide rod 711 moves to the protrusion 72, the top rod 71 is squeezed to move toward the connecting tube 52, and the connecting tube 52 will swing along the clamping shaft 531, thereby adjusting the overall position of the nozzle 521. This makes the temperature and humidity control more uniform.

[0044] When the push rod 71 moves, the slide plate 73 on the push rod 71 slides on the limit rod 731, and the distance between the slide plate 73 and the limit seat 732 becomes closer, so that the limit spring 733 between the two is compressed, and the limit spring 733 is used to facilitate the subsequent resetting operation.
