A temperature and humidity control system for a drawing frame

Abstract

This invention relates to the field of temperature and humidity control technology, and discloses a temperature and humidity control system for a drawing frame, including an industrial air conditioner, an air outlet hood, a base plate, a positioning ring, a sealing cover, a plug rod, and a collar. The invention incorporates a drive motor and a push rod. The drive motor rotates the base plate, which in turn rotates the positioning sleeve on the base plate, causing the sealing cover to rotate. The connecting pipe at the bottom of the sealing cover rotates the nozzle, causing the nozzle to rotate along with the base plate, thus changing the spray position. When the push rod and sealing cover move downwards, the side wall of the push rod moves along a spiral groove on a raised surface, further rotating the nozzle. A protrusion on the spiral groove presses the push rod towards the connecting pipe, changing the angle of the connecting pipe and continuously changing the position of the nozzle connected to it. This allows for spraying in different directions, ensuring more uniform temperature and humidity within the drawing frame.

Description

Technical Field

[0001] This invention belongs to the field of temperature and humidity control technology, specifically, it relates to a temperature and humidity control system for a drawing frame. Background Technology

[0002] In textile production, the drawing process plays a crucial role, improving the internal structure of the sliver and enhancing its uniformity and fiber straightness and parallelism. The temperature and humidity of the drawing frame's operating environment significantly impact sliver quality. Excessively high or low temperatures and humidity can alter the physical properties of the fibers. For example, high humidity causes fibers to absorb moisture, leading to unstable sliver weight and static electricity; excessively high temperatures can soften the fibers, affecting sliver strength and uniformity.

[0003] During use, it has been found that existing temperature and humidity control systems have issues because the air outlet is fixed inside the drawing frame, so the outlet angle does not change. Consequently, the regulated temperature and humidity cannot be evenly distributed inside the drawing frame, resulting in different temperatures and humidity levels at different locations within the drawing frame, which in turn affects the quality of the products produced by the equipment.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0014] In a preferred embodiment of the present invention, a connecting seat is installed on the positioning ring, a positioning rod is installed on the side wall of the connecting seat, and the end of the positioning rod is connected to the side wall of the air outlet hood.

[0015] In a preferred embodiment of the present invention, a fixed seat is mounted on the base plate, a rotating shaft is mounted on the fixed seat, the end of the rotating shaft is connected to the output end of the drive motor, a synchronous seat is mounted on the base plate, the synchronous shaft movably passes through the synchronous seat, the end of the synchronous shaft is connected to the fixed seat, and a torsion spring is sleeved on the side wall of the synchronous shaft, one end of the torsion spring is engaged with the synchronous seat, and the other end is engaged with the half gear.

[0016] In a preferred embodiment of the present invention, a strip groove is provided on the rocker plate, the extension line of the strip groove intersects with the synchronous shaft, a vertical plate is installed on the synchronous plate, and a sliding rod is installed on the side wall of the vertical plate, the sliding rod being slidably disposed on the strip groove.

[0017] In a preferred embodiment of the present invention, the positioning sleeve is provided with an air inlet cavity and a displacement cavity, which are blocked by a sealing cover. The air inlet cavity and the internal size of the sealing cover are adapted to each other. The air inlet is connected to the air inlet cavity, and the connecting pipe is placed inside the displacement cavity.

[0018] In a preferred embodiment of the present invention, the air inlet cavity is connected to the internal chamber of the sealing cover, a flexible hose is installed at the bottom of the sealing cover, the end of the flexible hose is connected to the connecting pipe, a retaining seat is installed at the bottom of the sealing cover, a retaining shaft is rotatably installed inside the retaining seat, and the end of the retaining shaft is rotatably connected to the side wall of the connecting pipe.

[0019] In a preferred embodiment of the present invention, a cross connecting plate is installed on the sealing cover, the cross connecting plate is rotatably connected to the insertion rod, a limiting plate is installed at the end of the insertion rod, the surface of the limiting plate is in contact with the side wall of the vertical plate, a return spring is installed on the insertion rod, one end of the return spring is engaged with the side wall of the positioning sleeve, and the other end of the return spring is engaged with the bottom of the limiting plate.

[0020] In a preferred embodiment of the present invention, a guide rod is installed at the end of the top rod, and the guide rod is slidably disposed in the lower sliding groove, which is a vertical sliding groove.

[0021] In a preferred embodiment of the present invention, a limiting seat is installed at the bottom of the sealing cover, a limiting rod is installed on the limiting seat, a sliding plate is slidably arranged on the limiting rod, the bottom of the sliding plate is connected to the side wall of the top rod, a limiting spring is sleeved on the limiting rod, one end of the limiting spring is engaged with the limiting seat, and the other end is engaged with the sliding plate.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] The machine is equipped with a drive motor, which can rotate the base plate. At this time, the positioning sleeve on the base plate can rotate the sealing cover, and the connecting pipe at the bottom of the sealing cover can rotate the nozzle. This causes the nozzle to rotate with the base plate, changing the position of the nozzle spray. This ensures that the sprayed gas can be evenly distributed in the inner cavity of the drawing frame, ensuring a relatively uniform temperature and humidity in the drawing frame.

[0024] The device is equipped with a half-gear, a first rack, and a second rack. The half-gear rotates with the base plate. When the half-gear contacts the first rack, it rotates to a certain angle. When the half-gear separates from the first rack, it resets. When the half-gear contacts the second rack, it rotates in the opposite direction to a certain angle and then resets. The half-gear can rotate periodically, which in turn drives the rocker plate to rotate. One side of the rocker plate can press the insert rod and sealing cover downwards, thus moving the nozzle downwards. The other side of the rocker plate can drive the nozzle upwards, retracting and closing the nozzle. Through the reciprocating rotation of the rocker plate, it ensures that only one side of the nozzle is open, increasing the gas flow rate at the nozzle and allowing the gas to flow to a farther location, ensuring more uniform temperature and humidity control.

[0025] With the addition of a push rod, as the push rod and sealing cover move downwards, the side wall of the push rod can move along the spiral groove on the raised surface. At this time, the push rod and connecting pipe drive the nozzle to rotate. The spiral groove has a protrusion that presses the push rod towards the connecting pipe. The angle of the connecting pipe changes due to the pressure from the push rod, and the position of the nozzle connected to the connecting pipe changes continuously, allowing spraying in different directions and ensuring that the temperature and humidity in the drawing frame become more uniform.

[0026] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0045] To make the objectives, 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 with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention.

[0046] Example 1:

[0047] like Figures 1 to 9 As shown, a temperature and humidity control system for a drawing frame includes an industrial air conditioner 1, an air outlet hood 2, a base plate 4, a pair of positioning rings 3, a sealing cover 5, an insert rod 6, and a collar 7.

[0048] 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 existing technology, so its working principle will not be described in detail here.

[0049] The base plate 4 is rotatably installed at the bottom of the air outlet hood 2. Several pairs of positioning sleeves 41 are installed on the base plate 4. An air inlet 411 is opened on the air outlet hood 2.

[0050] A pair of positioning rings 3 are placed in the inner cavity of the air outlet hood 2. A drive motor 35 is installed on the base plate 4. A synchronous shaft 341 is rotatably installed on the base 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. The positioning rings 3 are vertically distributed. Several pairs of first racks 32 are installed on the lower positioning ring 3. Several pairs of second racks 33 are installed on the upper positioning ring 3. Each pair of first racks 32 and second racks 33 are staggered and correspond to each other. There is a gap between adjacent first racks 32 and second racks 33. The first racks 32 and second racks 33 are adapted to the half gear 34. A torsion spring 342 is snapped on the synchronous shaft 341. A rocker plate 36 is installed on the synchronous shaft 341. A synchronous plate 37 is slidably arranged on the side wall of the rocker plate 36. The synchronous plate 37 is vertically corresponding to the positioning sleeve 41.

[0051] The sealing cover 5 is slidably disposed in the inner cavity of the positioning sleeve 41. A connecting pipe 52 is connected to the bottom of the sealing cover 5, and a nozzle 521 is installed at the end of the connecting pipe 52.

[0052] The insertion rod 6 moves 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.

[0053] The drive 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 rotates with the base plate 4. The position of the nozzle 521 changes, ensuring that the sprayed gas can be evenly distributed in the inner cavity of the drawing frame, ensuring that there is a relatively uniform temperature and humidity in the drawing frame. Furthermore, during the rotation of the half gear 34 following the base plate 4, when the half gear 34 contacts the first rack 32, the half gear 34 rotates to a certain angle. 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 to a certain angle and then resets. Thus, the half gear 34 can periodically reciprocate, thereby driving the rocker plate 36 to rotate. One side of the rocker plate 36 can squeeze the insert rod 6 and the sealing cover 5 downward, thereby moving the nozzle 521 downward. The other side of the rocker plate 36 can drive the nozzle 521 upward, storing and closing the nozzle 521. Through the reciprocating rotation of the rocker plate 36, it is ensured that only one side of the nozzle 521 is open, increasing the flow rate of the gas sprayed at the nozzle 521, allowing the gas to flow to a farther location, and ensuring more uniform temperature and humidity control.

[0054] The collar 7 slides on the side wall of the connecting pipe 52. A push rod 71 is rotatably installed on the side wall of the collar 7. The push rod 71 slides horizontally below the sealing cover 5. Several pairs of protrusions 72 are installed on the positioning sleeve 41. The several pairs of protrusions 72 are spirally distributed. The several pairs of protrusions 72 and the side wall of the positioning sleeve 41 are provided with spiral grooves 721. The end of the spiral grooves 721 is connected to a downward groove 722. The downward groove 722 is slidably connected to the push rod 71. When the top rod 71 and the sealing cover 5 move downwards, the side wall of the top rod 71 can move along the spiral groove 721 on the surface of the protrusion 72. Therefore, the top rod 71 and the connecting pipe 52 drive the nozzle 521 to rotate. The spiral groove 721 is provided with a protrusion 72. The protrusion 72 squeezes the top rod 71 to move towards the connecting pipe 52. The angle of the connecting pipe 52 changes due to the pressure of the top rod 71. The position of the nozzle 521 connected to the connecting pipe 52 is constantly changing, which can spray in different directions to ensure that the temperature and humidity in the drawing frame become more uniform.

[0055] like Figures 1 to 9 As shown in the specific embodiment, the industrial air conditioner 1 has a support frame 12 installed at its bottom, and the support frame 12 has positioning holes. An air supply duct 11 is installed on the air outlet of the industrial air conditioner 1, and a cover plate 21 is installed on the air outlet hood 2. The cover plate 21 has a connection port 211, and the end of the connection port 211 is connected to the end of the air supply duct 11. The industrial air conditioner 1 can 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.

[0056] like Figures 1 to 9 As shown, a connecting seat 31 is further 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 connected to the side wall of the air outlet hood 2. The connecting seat 31 and the positioning rod 311 limit the installation position of the positioning ring 3.

[0057] Example 2:

[0058] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, a fixed seat 344 is installed on the base plate 4, and 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 drive 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. A torsion spring 342 is sleeved on the side wall of the synchronous shaft 341. One end of the torsion spring 342 is engaged with the synchronous seat 343, and the other end is engaged with 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 synchronous shaft 341 to rotate at a certain angle, and at this time the torsion spring 342 will rotate synchronously. When the half gear 34 and the first rack 32 separate, the torsion spring 342 will drive the half gear 34 to reset. After moving a certain distance, the half gear 34 will mesh with the second rack 33, and then the half gear 34 will drive the synchronous shaft 341 to rotate in the opposite direction at a certain angle. Through the continuous meshing of the half gear 34 with the first rack 32 and the second rack 33, the half gear 34 and the synchronous shaft 341 will rotate periodically back and forth.

[0059] like Figures 1 to 9 As shown, in a specific embodiment, a strip groove 361 is provided on the rocker 36, and the extension line of the strip groove 361 intersects with the synchronous shaft 341. A vertical plate 371 is installed on the synchronous plate 37, and a sliding rod 372 is installed on the side wall of the vertical plate 371. The sliding rod 372 is slidably disposed on the strip groove 361. During the rotation of the rocker 36, the sliding rod 372 on the rocker 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 insert rod 6 and the sealing cover 5, and the nozzle 521 at the bottom of the sealing cover 5 can move downward synchronously.

[0060] like Figures 1 to 9 As shown, the positioning sleeve 41 further includes an air inlet cavity 412 and a displacement cavity 413, which are blocked by the sealing cover 5. The air inlet cavity 412 and the internal dimensions of the sealing cover 5 are compatible. The air inlet 411 is connected to the air inlet cavity 412, and the connecting pipe 52 is placed inside the displacement cavity 413. When the sealing cover 5 moves downward, the side wall of the sealing cover 5 can slide inside the air inlet cavity 412. When the air inlet 411 is not blocked by the sealing cover 5, the gas inside the air outlet hood 2 enters the sealing cover 5 through the air inlet 411 and is then easily ejected from the nozzle 521 through the connecting pipe 52.

[0061] Example 3:

[0062] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, the air inlet chamber 412 is connected to the internal chamber of the sealing cover 5. A flexible hose 511 is installed at the bottom of the sealing cover 5, and the end of the flexible hose 511 is connected to the connecting pipe 52. A retaining seat 53 is installed at the bottom of the sealing cover 5, and a retaining shaft 531 is rotatably installed inside the retaining seat 53. The end of the retaining shaft 531 is rotatably connected to the side wall of the connecting pipe 52.

[0063] like Figures 1 to 9 As shown, in a specific embodiment, a cross-shaped connecting plate 51 is installed on the sealing cover 5. The cross-shaped connecting plate 51 is rotatably connected to the insertion rod 6. A limiting plate 62 is installed at the end of the insertion rod 6. The surface of the limiting plate 62 is in contact with the side wall of the vertical plate 371. A return spring 61 is installed on the insertion rod 6. One end of the return spring 61 is engaged with the side wall of the positioning sleeve 41, and the other end of the return spring 61 is engaged with the bottom of the limiting plate 62. When the sealing cover 5 moves, the insertion rod 6 on the sealing cover 5 moves downward synchronously. The limiting plate 62 at the top of the insertion rod 6 slides downward, and the return spring 61 at the bottom of the limiting plate 62 is compressed. The return spring 61 facilitates subsequent reset operations.

[0064] like Figures 1 to 9 As shown, further, a guide rod 711 is installed at the end of the top rod 71. The guide rod 711 is slidably disposed in the lower sliding groove 722, which is a vertical sliding groove. A limit seat 732 is installed at the bottom of the sealing cover 5. A limit rod 731 is installed on the limit seat 732. A sliding plate 73 is slidably disposed on the limit rod 731. The bottom of the sliding 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 engaged with the limit seat 732, and the other end is engaged with the sliding plate 73. When the top rod 71 moves, the sliding plate 73 on the top rod 71 slides on the limit rod 731, and the distance between the sliding plate 73 and the limit seat 732 becomes closer. As a result, the limit spring 733 between the two is compressed, which facilitates the subsequent reset operation.

[0065] The implementation principle of a temperature and humidity control system for a drawing frame in this embodiment is as follows:

[0066] When temperature and humidity need to be regulated, the operator needs to start the industrial air conditioner 1. The industrial air conditioner 1 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.

[0067] At the same time, the operator needs to start the drive motor 35, which can drive the rotating shaft 351 to rotate. The rotating shaft 351 synchronously drives the fixed seat 344 to rotate. The fixed seat 344 is connected to the base plate 4, so the base plate 4 can rotate synchronously. At this time, the positioning sleeve 41 on the base plate 4 can drive the sealing cover 5 to rotate. The connecting pipe 52 at the bottom of the sealing cover 5 can drive the nozzle 521 to rotate, so that the nozzle 521 rotates with the base plate 4. The position of the nozzle 521 changes, ensuring that the sprayed gas can be evenly distributed in the inner cavity of the drawing frame, ensuring a relatively uniform temperature and humidity in the drawing frame.

[0068] The base plate 4 is connected to a synchronous shaft 341 via a synchronous seat 343. The synchronous shaft 341 is connected to a half gear 34, which then rotates synchronously with the base plate 4. The half gear 34 rotates within the gap between the two positioning rings 3.

[0069] When the half gear 34 first meshes with the first rack 32, as the meshing continues, the half gear 34 will drive the synchronous shaft 341 to rotate at a certain angle, and at this time the torsion spring 342 will rotate synchronously. When the half gear 34 and the first rack 32 separate, the torsion spring 342 will drive the half gear 34 to reset. After moving a certain distance, the half gear 34 will mesh with the second rack 33, and then the half gear 34 will drive the synchronous shaft 341 to rotate in the opposite direction at a certain angle. Through the continuous meshing of the half gear 34 with the first rack 32 and the second rack 33, the half gear 34 and the synchronous shaft 341 will rotate periodically back and forth.

[0070] At this time, the rocker plate 36 on the half gear 34 rotates synchronously, and the slide bar 372 on the rocker plate 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 insert rod 6 and the sealing cover 5, while the nozzle 521 at the bottom of the sealing cover 5 can move downward synchronously.

[0071] When one side of the rocker arm 36 can press the insert rod 6 and the sealing cover 5 downwards, the nozzle 521 will move downwards. Meanwhile, the other side of the rocker arm 36 can drive the nozzle 521 upwards, retracting the nozzle 521 and blocking the air inlet 411, thus closing the nozzle 521 on that side. Through the reciprocating rotation of the rocker arm 36, it is ensured that only one side of the nozzles 521 is open, ensuring that the gas inside the air outlet hood 2 can only be sprayed out along the nozzle 521 on one side, increasing the gas flow rate at the nozzle 521, allowing the gas to flow to a farther location, and ensuring that the temperature and humidity can be controlled more evenly.

[0072] When the sealing cover 5 moves downward, the side wall of the sealing cover 5 can slide inside the air inlet cavity 412. When the air inlet 411 is not blocked by the sealing cover 5, the gas inside the air outlet hood 2 enters the sealing cover 5 through the air inlet 411 and is then easily sprayed out from the nozzle 521 through the connecting pipe 52.

[0073] When the sealing cover 5 moves, the insertion rod 6 on the sealing cover 5 moves downward synchronously, the limiting plate 62 at the top of the insertion rod 6 slides downward, and the reset spring 61 at the bottom of the limiting plate 62 is compressed, which facilitates the reset operation later.

[0074] When the sealing cover 5 moves the connecting pipe 52 downwards, the top rod 71 on the side wall of the connecting pipe 52 drives the guide rod 711 to slide along the downward groove 722. At this time, the connecting pipe 52 is in a vertical state. Then, the guide rod 711 slides along the spiral groove 721, thereby causing the sealing cover 5, the connecting pipe 52, and the nozzle 521 to rotate, thus spraying in different directions. 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 towards the connecting pipe 52. At this time, the connecting pipe 52 will swing along the retaining shaft 531, thereby adjusting the overall position of the nozzle 521. This makes the temperature and humidity control more uniform.

[0075] 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. As a result, the limit spring 733 between the two is compressed, and the limit spring 733 facilitates the subsequent reset operation.
