Description

Technical Field

[0001] This utility model relates to the field of textile manufacturing technology, specifically to a pretreatment mechanism for dyeing polyester fabric. Background Technology

[0002] In recent years, the textile manufacturing industry in my country has developed rapidly. However, traditional fabric dyeing processes involve the extensive use of corrosive and toxic chemicals, resulting in pure cotton fabrics containing residual formaldehyde, carcinogenic or allergenic banned azo dyes, and heavy metal ions such as lead, chromium, cadmium, cobalt, and mercury. These contaminants pose a health risk, especially to clothing worn close to the skin. To address this issue, existing fabric pretreatment methods, such as low-temperature plasma treatment, aim to improve dyeing performance. However, this pretreatment requires intermittent fabric transport, while current conveyor systems are typically continuous, making them inconvenient to use.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing a polyester fabric dyeing pretreatment mechanism that can intermittently convey fabric and is convenient and easy to operate.

[0005] The solution adopted by this utility model to solve the technical problem is: a pretreatment mechanism for dyeing polyester fabric, including a frame, a conveying mechanism, a plasma nozzle, a plasma generator, and a moving mechanism. The conveying mechanism is mounted on the frame, and the moving mechanism includes a slide rail, a slider, and a driver for driving the slider to reciprocate on the slide rail. The slide rail is located above the conveying mechanism, and the length direction of the slide rail is perpendicular to the conveying direction of the conveying mechanism. The plasma nozzle is mounted on the slider and is connected to the plasma generator.

[0006] Furthermore, in order to drive the first conveying roller and the second conveying roller to rotate intermittently, the conveying mechanism includes a frame, a first conveying roller, a second conveying roller, and a drive motor. The first conveying roller and the second conveying roller are respectively rotatably mounted on both sides of the frame. There are two drive motors, which are respectively connected to the first conveying roller and the second conveying roller through an intermittent mechanism to drive the first conveying roller and the second conveying roller to rotate intermittently.

[0007] Furthermore, in order to drive the first and second conveying rollers to rotate intermittently, the intermittent mechanism includes a drive disk, an intermittent disk, and an intermittent assembly. A drive shaft is rotatably mounted on the frame and is connected to a drive motor. There are two drive disks and two intermittent disks. The two drive disks are coaxially fixedly mounted on both sides of the drive shaft, and the two intermittent disks are coaxially fixedly mounted on both sides of the first and second conveying rollers. The drive disk is located beside the intermittent disk. The drive disk drives the intermittent disk to rotate intermittently through the intermittent assembly, thereby driving the first and second conveying rollers to rotate intermittently.

[0008] Furthermore, in order to drive the intermittent disk to rotate, the intermittent assembly includes several cam grooves, cam posts, paddle blocks, and paddle levers. The cam grooves are formed by the radial inward recess of the drive disk, and the cam posts are formed by the axial outward protrusion of the intermittent disk. The diameter of the cam posts is smaller than the groove diameter of the cam grooves, and the distance between the center point of the cam posts and the center point of the drive disk is smaller than the diameter of the drive disk, so that the cam posts can be engaged in the cam grooves to drive the intermittent disk to rotate, thereby driving the paddle blocks to move the paddle levers. The lever is radially arranged on the intermittent disk, and the block is axially arranged on the drive disk. The distance between the center point of the block and the center point of the intermittent disk is less than the length of the lever, so that the intermittent disk can be rotated by the block moving the lever, so that the cam column can be engaged in the cam groove, thereby driving the intermittent disk to rotate.

[0009] Furthermore, in order to drive the drive shaft to rotate, the drive motor is mounted on the frame, a drive wheel is coaxially fixedly mounted on the motor shaft of the drive motor, and a driven wheel is coaxially fixedly mounted on the drive shaft. The drive wheel is connected to the driven wheel via a belt to drive the drive shaft to rotate.

[0010] Compared with existing technologies, this invention has the following advantages: This invention intermittently conveys textile fabric and uses a plasma nozzle to perform surface treatment on the fabric, thereby improving the dyeing performance of the fabric. During use, to ensure that the movement speed of the plasma nozzle matches the fabric conveying speed, the fabric remains stationary as the plasma nozzle moves from left to right. When the plasma nozzle reaches the far right, a unit amount of fabric is conveyed, allowing the plasma nozzle to begin a new round of surface treatment. Compared with traditional conveying mechanisms, this method is more efficient. Specifically, when the drive shaft rotates, it drives the drive disc to rotate. The cam post engages in the cam groove, and the rotation of the drive disc drives the intermittent disc to rotate. When the cam groove separates from the cam post, the intermittent disc stops rotating, while the drive disc continues to rotate. Then, the lever contacts the lever, and the lever moves the intermittent disc again. When the lever separates from the lever, the intermittent disc stops rotating again, and the drive disc continues to rotate, causing the cam groove to contact the cam post again, thus achieving intermittent conveying of the textile fabric. This method is very convenient to use. Attached Figure Description

[0015] In this embodiment, in order to drive the first conveying roller 2 and the second conveying roller 9 to rotate intermittently, the intermittent mechanism includes a drive disk 3, an intermittent disk 4, and an intermittent assembly. A drive shaft 5 is rotatably mounted on the frame 1. The drive shaft 5 is connected to the drive motor 8. There are two drive disks 3 and two intermittent disks 4. The two drive disks 3 are coaxially fixedly mounted on both sides of the drive shaft 5, and the two intermittent disks 4 are coaxially fixedly mounted on both sides of the first conveying roller 2 and the second conveying roller 9. The drive disk 3 is located beside the intermittent disk 4. The drive disk 3 drives the intermittent disk 4 to rotate intermittently through the intermittent assembly, thereby driving the first conveying roller 2 and the second conveying roller 9 to rotate intermittently.

[0016] In this embodiment, in order to drive the intermittent disk 4 to rotate, the intermittent assembly includes several cam grooves 301, cam posts 401, paddle blocks 302, and paddle levers 402. The cam grooves 301 are formed by the radial inward recess of the drive disk 3, and the cam posts 401 are formed by the axial outward protrusion of the intermittent disk 4. The diameter of the cam posts 401 is smaller than the groove diameter of the cam grooves 301, and the distance between the center point of the cam posts 401 and the center point of the drive disk 3 is smaller than the diameter of the drive disk 3, so that the intermittent disk 4 can be driven to rotate by the cam posts 401 being inserted into the cam grooves 301, thereby driving the paddle blocks 302 to paddle levers 402. The lever 402 is radially arranged on the intermittent disk 4, and the lever block 302 is axially arranged on the drive disk 3. The distance between the center point of the lever block 302 and the center point of the intermittent disk 4 is less than the length of the lever 402, so that the lever 402 is moved by the lever block 302 to drive the intermittent disk 4 to rotate, so that the cam column 401 is engaged in the cam groove 301, thereby driving the intermittent disk 4 to rotate.

[0017] In this embodiment, in order to drive the drive shaft 5 to rotate, the drive motor 8 is mounted on the frame 1, the drive motor 8 has a drive wheel 6 coaxially fixedly mounted on the motor shaft, and the drive shaft 5 has a driven wheel 7 coaxially fixedly mounted on the drive shaft 5.

[0018] In this embodiment, the drive assembly includes a drive motor 8, a drive wheel 6, and a driven wheel 7. The drive motor 8 is mounted on the frame 1. The drive wheel 6 is coaxially fixedly mounted on the motor shaft of the drive motor 8. The driven wheel 7 is coaxially fixedly mounted on the drive shaft 5.

[0019] This utility model intermittently conveys textile fabric 11, and works with a plasma nozzle 10 to perform surface treatment on the textile fabric 11 to improve the subsequent dyeing performance of the textile fabric 11. During use, to ensure that the moving speed of the plasma nozzle 10 matches the conveying speed of the fabric 11, the fabric 11 remains stationary while the plasma nozzle 10 moves from left to right. When the plasma nozzle 10 reaches the far right, a unit amount of fabric 11 is conveyed, allowing the plasma nozzle 10 to begin a new round of surface treatment on the fabric 11. Compared to traditional conveying mechanisms, this method is more efficient. Specifically, when the drive shaft 5 rotates, it drives the... When disk 3 rotates, cam post 401 engages with cam groove 301. Rotating disk 3 drives intermittent disk 4 to rotate. When cam groove 301 separates from cam post 401, intermittent disk 4 stops rotating, while disk 3 continues to rotate. Then, lever 302 contacts lever 402, which moves lever 402, causing intermittent disk 4 to rotate again. When lever 302 separates from lever 402, intermittent disk 4 stops rotating again, while disk 3 continues to rotate, causing cam groove 301 to contact cam post 401 again. This achieves intermittent conveying of textile fabric 11, which is very convenient to use.
