Description

Technical Field

[0001] This utility model relates to the field of printing and dyeing equipment, specifically to a dye recovery device for printing and dyeing machines. Background Technology

[0002] Dyeing and printing is a major processing method in textile manufacturing. The dyeing and printing process consists of multiple steps. After pretreatment, dyeing and printing are carried out, followed by finishing and finally washing. Dyeing textiles requires immersing them in dye and then drying them.

[0003] After textile dyeing, residual dye drips directly onto the surface, causing waste. Therefore, existing technologies use scrapers to remove residual dye from the textile surface. While scraping away the dye, the scraper also scrapes away some fiber impurities. Traditional static scrapers cannot remove these impurities, causing them to accumulate on the scraper. Furthermore, the friction between the scraper and the textile is relatively high, posing a risk of jamming. As a result, the removal rate of residual dye on the textile surface is low, and it may even damage the textile. Utility Model Content

[0004] The purpose of this invention is to provide a dye recovery device for a printing and dyeing machine. This device uses a vibration mechanism to drive the scraper to vibrate and impact the textile, thereby shaking off impurities and dyes attached to the scraper, reducing the risk of jamming, and improving the dye removal rate.

[0005] The technical solution adopted by this utility model to solve the above problems is:

[0006] A dye recovery device for a printing and dyeing machine includes a frame and a dyeing vat. The dyeing vat is fixed at the bottom of the frame. Textiles enter the dyeing vat and are removed from it under the driving action of a guide roller group. The frame is equipped with a scraper and a vibration mechanism. After the textiles are removed from the dyeing vat, they abut against the upper end of the scraper. The vibration mechanism drives the scraper to vibrate up and down.

[0007] In the above technical solution, preferably, the vibration mechanism includes two sets of first motors and cams. Limiting holes are provided on the left and right sides of the frame. Extension rods are fixed at both ends of the scraper. The extension rods are slidably arranged in the limiting holes. A cam is rotatably arranged on the frame below the extension rods. The first motors drive the cams to rotate and the cams intermittently contact the extension rods when they rotate. A first spring is provided above the extension rods to drive the extension rods to move downwards.

[0008] In the above technical solution, preferably, a clamping mechanism is provided inside the frame. The clamping mechanism includes two clamping roller groups, which are symmetrically arranged in front and behind inside the frame. Each clamping roller group includes two clamping rollers arranged vertically and parallel to each other, and a scraper is located in the middle of the two clamping roller groups.

[0009] In the above technical solution, preferably, a collection mechanism is provided inside the frame. The collection mechanism includes an inclined plate and a material bucket. The upper end of the inclined plate is located below the scraper, and the lower end of the inclined plate is located inside the material bucket. The material bucket is fixed on the frame.

Detailed Implementation

[0020] The present invention will be further described in detail below with reference to the accompanying drawings and through embodiments. The following embodiments are explanations of the present invention, but the present invention is not limited to the following embodiments.

[0021] See Figures 1-5 This embodiment provides a dye recovery device for a printing and dyeing machine, including a frame 1 and a dyeing vat 2. The dyeing vat 2 is fixed at the bottom of the frame 1. The textile 8 enters the dyeing vat 2 and is then removed from the dyeing vat 2 under the driving action of the guide roller group 3. The frame 1 is equipped with a scraper 4 and a vibration mechanism 5. After the textile 8 is removed from the dyeing vat 2, it abuts against the upper end of the scraper 4. The vibration mechanism 5 drives the scraper 4 to vibrate up and down.

[0022] This invention utilizes a vibration mechanism 5 to vibrate the scraper 4 up and down, causing impurities and dyes adhering to the scraper 4 to be shaken off, reducing the risk of impurities and dyes solidifying and accumulating on the scraper 4. Simultaneously, it creates intermittent contact between the scraper 4 and the textile 8, reducing the risk of jamming between them and decreasing friction, thus minimizing damage to the textile 8. The instantaneous impact force generated by the vibration of the scraper 4 can penetrate the fiber gaps of the textile 8, squeezing out deeply adhered dyes, thereby improving dye recovery rate.

[0023] See Figure 1 , Figure 4 , Figure 5 The vibration mechanism 5 includes two sets of first motors 51 and cams 52. Limiting holes 11 are provided on the left and right sides of the frame 1. Extension rods 41 are fixed at both ends of the scraper 4. The extension rods 41 are slidably arranged in the limiting holes 11. A cam 52 is rotatably arranged on the frame 1 below the extension rods 41. The first motors 51 drive the cams 52 to rotate and the cams 52 intermittently contact the extension rods 41 when rotating. A first spring 53 is provided above the extension rods 41 to drive the extension rods 41 to move downward.

[0024] The first motor 51 drives the cam 52 to rotate, thereby causing the extension rod 41 to move upward. The extension rod 41 moves downward to reset under the action of the first spring 53. Thus, the cam 52 and the first spring 53 drive the extension rod 41 and the scraper 4 to move up and down, thereby achieving the vibration effect of the scraper 4. The vibration frequency of the scraper 4 can be adjusted by adjusting the speed of the first motor 51, thereby adjusting the impact force of the scraper 4. This method is suitable for use on textiles 8 of different materials or thicknesses.

[0025] See Figure 2 , Figure 3 The frame 1 is provided with a clamping mechanism 6, which includes two clamping roller groups 61. The two clamping roller groups 61 are symmetrically arranged in front and behind in the frame 1. Each clamping roller group 61 includes two clamping rollers 62 arranged vertically and parallel to each other. The scraper 4 is located in the middle of the two clamping roller groups 61.

[0026] By passing the textile 8 sequentially between the two clamping rollers 62 within the two clamping roller groups 61, the textile 8 located between the two clamping roller groups 61 is placed in a horizontal state due to the clamping action of the two clamping roller groups 61. At this time, the direction of the impact force of the vertically moving scraper 4 on the textile 8 is perpendicular to the textile 8, thereby improving the impact effect of the scraper 4 on the textile 8, which can improve the dye extrusion rate and dye recovery rate within the textile 8.

[0027] See Figure 2 , Figure 3 The frame 1 is provided with a collection mechanism 7, which includes an inclined plate 71 and a material bucket 72. The upper end of the inclined plate 71 is located below the scraper 4, and the lower end of the inclined plate 71 is located inside the material bucket 72. The material bucket 72 is fixed on the frame 1.

[0028] The dye inside the textile 8 is scraped off by the scraper 4 and falls into the inclined plate 71 and then into the material bucket 72 for collection. This facilitates the centralized processing of the recovered dye and improves the convenience of dye recovery operation of this device.

[0029] See Figure 1 , Figure 4 , Figure 5 The inclined plate 71 is fixed with horizontal rods 73 at both ends. The frame 1 has sliding holes 12 on both sides. The horizontal rods 73 are slidably disposed in the sliding holes 12. The lower end of the inclined plate 71 is rotatably disposed in the material bucket 72. The horizontal rods 73 are located below the cam 52 and the cam 52 is in intermittent contact with the horizontal rods 73 when it rotates. The lower end of the horizontal rods 73 is provided with a second spring 74 that drives the horizontal rods 73 to move upward.

[0030] The first motor 51 drives the cam 52 to rotate, causing the horizontal rod 73 to move downwards. The horizontal rod 73 then moves upwards to its original position under the action of the second spring 74. This, in turn, drives the horizontal rod 73 and the sliding hole 12 of the inclined plate 71 to rotate reciprocally, achieving the vibration effect of the inclined plate 71. This utilizes inertia to reduce the probability of dye solidifying after adhering to the inclined plate 71 for a period of time, allowing the dye to fall into the material bucket 72 for collection. By simultaneously driving the scraper 4 and the inclined plate 71 to vibrate using the first motor 51 and the cam 52, the number of motors in the device is reduced, thereby lowering the structural complexity and energy consumption of the device.

[0031] See Figure 2 The guide roller group 3 includes two active rollers 31 and three driven rollers 32. The two active rollers 31 are rotatably mounted at the front and rear ends of the upper end of the frame 1, respectively. A second motor 33 is mounted on the frame 1. The second motor 33 drives the two active rollers 31 to rotate through a synchronous belt mechanism. The three driven rollers 32 are rotatably mounted in the dyeing vat 2.

[0032] By sequentially winding the textile 8 around the front drive roller 31, driven roller 32, clamping roller 62 and the rear drive roller 31, and driving the textile 8 to move by the second motor 33, the continuous input, dyeing, dye removal and output of the textile 8 are realized, which improves the automation level and dyeing efficiency of the device and is beneficial to the batch dyeing of textile 8.

Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not depart from the content of this specification or exceed the scope defined in the claims, all of which shall fall within the protection scope of this invention.
