Description

Technical Field

[0001] The utility model relates to the technical field of fabric processing, in particular to a drying device for knitting bleaching and dyeing. Background Art

[0002] During the bleaching and dyeing process of knitted fabrics, the knitted fabrics need to be washed and bleached before being dyed. After dyeing, in order to ensure that the color on the knitted fabrics does not fade, they need to be dried before proceeding to the next step. Therefore, a drying device is required to dry the knitted fabrics.

[0003] Most of the existing knitted fabric dryers convey the knitted fabric into a box, and use a fan or electric heating in the box to increase the temperature in the box, so as to dry the knitted fabric passing through the box. This method not only has a relatively low drying efficiency for the knitted fabric, but also makes it difficult to completely discharge the moisture inside the knitted fabric. In addition, when the knitted fabric is fed in and out, the feed port and the discharge port cannot be blocked, which causes the heat in the box to flow out quickly, thereby reducing the drying effect of the knitted fabric. There is still room for improvement. Utility Model Content

The output end of the second motor 10 is fixedly connected to a positive and negative threaded rod 11. A slide groove is provided on the front of the bar frame 9. The bottom end of the positive and negative threaded rod 11 is rotatably connected to the inner bottom wall of the slide groove.

[0023] The inner wall of the chute is slidably connected to two sliders 12, and the upper surfaces of the two sliders 12 are provided with threaded holes. The two sliders 12 are threadedly connected to the positive and negative threads on the surfaces of the positive and negative threaded rods 11 through the threaded holes. The front surfaces of the two sliders 12 are fixedly connected to strip plates 13, and the inner walls of the two strip plates 13 are fixedly connected to electric heating plates 14. The opposite surfaces of the two electric heating plates 14 are fixedly connected to ironing plates 15. The inner wall of the drying box 1 is rotatably connected to a guide roller 16;

[0024] When the knitted fabric moves to the middle position between the two ironing plates 15, the second motor 10 drives the forward and reverse screw rods 11 to rotate, thereby driving the two strip plates 13 to move toward the opposite surfaces through the two sliders 12, thereby driving the ironing plates 15 heated by the electric heating plate 14 to move toward the opposite surfaces, and finally contacting the upper and lower surfaces of the knitted fabric, and using the high temperature on the surface of the ironing plate 15 to quickly take away the moisture in the knitted fabric, and the hot air blower 7 can blow air into the drying box 1 through the air outlet 8, further increasing the temperature in the drying box 1, thereby increasing the drying efficiency of the knitted fabric.

[0025] Example 2: Reference Figure 1 、 Figure 2 and Figure 3 The inner bottom walls of the feed hole and the discharge hole are rotatably connected to the bottom roller 17, the inner top walls of the feed hole and the discharge hole are provided with a movable groove, the inner wall of the movable groove is slidably connected to a movable plate 18, the front faces of the two movable plates 18 are fixedly connected to a transmission block 19, the lower surface of the movable plate 18 is rotatably connected to a pressure roller 20, the position of the pressure roller 20 corresponds to that of the bottom roller 17, and the length of the pressure roller 20 and the bottom roller 17 are the same as the length of the feed hole and the discharge hole respectively;

[0026] The front of the drying box 1 is fixedly connected to the positions corresponding to the two movable grooves with a positioning frame 21, the upper surface of the positioning frame 21 is fixedly connected to the third motor 22, the output end of the third motor 22 is fixedly connected to a threaded rod 23, and the back of the positioning frame 21 is provided with a movable groove, the bottom end of the threaded rod 23 is rotatably connected to the inner bottom wall of the movable groove, the front end of the transmission block 19 extends to the inside of the movable groove and is slidably connected to the inner wall of the movable groove, and the transmission block 19 is threadedly connected to the threaded rod 23, and a rectangular hole is provided on the front of the drying box 1, and a mounting plate 24 is inserted into the inner wall of the rectangular hole. The front of the mounting plate 24 is threadedly connected to two mounting bolts 25, and the back of the mounting plate 24 is rotatably connected to two round shafts 26, and the surfaces of the two round shafts 26 are fixedly connected to the hair-sticking rollers 27;

[0027] The third motor 22 can drive the threaded rod 23 to rotate, thereby driving the transmission block 19 and the movable plate 18 to descend. During the descending process, the movable plate 18 can drive the pressure roller 20 to contact the surface of the bottom roller 17, pressing the knitted fabric and squeezing out its moisture, while improving the sealing effect in the drying box 1, thereby reducing the heat loss rate in the drying box 1 and further improving the drying effect of the knitted fabric. At the same time, the two lint-sticking rollers 27 can scrape off the fiber fluff on the surface of the knitted fabric after contacting the knitted fabric, thereby improving the production quality of the knitted fabric.

[0028] Working principle: First, the knitted fabric on the unwinding roller 5 is passed through the feed hole, placed on the guide roller 16, and passed between the two lint-sticking rollers 27, and then passed through the discharge hole to connect with the winding roller 6. At this time, the first motor 4 drives the winding roller 6 and the unwinding roller 5 to rotate, thereby driving the knitted fabric to move in the drying box 1. During the movement, first, the third motor 22 can drive the two movable plates 18 to descend through the threaded rod 23, thereby driving the pressure roller 20 to press the bottom roller 17, so that the knitted fabric can squeeze out the moisture when passing between the bottom roller 17 and the pressure roller 20. At the same time, after the pressure roller 20 presses the bottom roller 17, it can improve the sealing effect in the drying box 1 and avoid rapid heat loss. At this time, the hot air blower 7 is started and blows hot air into the drying box 1 through the air outlet 8. , thereby increasing the overall temperature in the drying box 1. At the same time, when the knitted fabric moves to the middle position of the two ironing plates 15, the second motor 10 starts and drives the two sliders 12 to move toward the opposite surfaces through the positive and negative screw rods 11, thereby driving the two ironing plates 15 to press the upper and lower surfaces of the knitted fabric tightly through the two strip plates 13. When pressed by the ironing plates 15, the two first motors 4 stop running, and the electric heating plates 14 can heat the ironing plates 15. After the ironing plates 15 come into contact with the knitted fabric, they can quickly transfer heat to the knitted fabric, thereby improving the drying efficiency of the knitted fabric. After completion, the knitted fabric comes into contact with the two lint-sticking rollers 27, and the two lint-sticking rollers 27 can scrape off the fiber fluff on the surface of the knitted fabric, thereby improving the production quality of the knitted fabric.
