Description

TECHNICAL FIELD

[0001] The utility model belongs to drying device technical field, and specifically relates to a kind of textile printing and dyeing drying device. BACKGROUND

[0002] Textile printing and dyeing is the process of dyeing or printing textile materials by dye or paint, including pretreatment, dyeing, printing and finishing and other links, so that fabric obtains color, pattern or specific function. Among them, dyeing is to immerse the whole fabric with color, while printing is to apply dye locally to form pattern, and the principles of the two are similar but the processes are different. Modern printing and dyeing technology not only improves the appearance of textile, but also endows it with functions such as waterproofness and antibacterial property, and it is a key link in textile industry chain to improve added value. This process has a long history, and as early as in the Neolithic Age, there was practice of dyeing with mineral pigments.

[0003] One of the key links in printing and dyeing process is drying, which refers to removing water from fabric after dyeing or printing to fix color, improve color fastness and ensure fabric size stability, directly affecting the final hand feeling and quality of textile.

[0004] The common drying method at present is hot air drying, but pure hot air drying has problems such as high energy consumption and uneven temperature distribution. For example, conventional hot air drying relies on single heat source conduction, which is difficult to accurately adapt to the temperature sensitivity of different fibers (such as cotton and chemical fibers), and is easy to cause fabric color difference or fiber damage; the open hot air system has serious heat loss, and the thermal efficiency is less than 40%, and the waste gas emission lacks waste heat recovery mechanism, which does not meet the green production requirements.

[0031] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] Example 1:

[0033] like Figures 1-5 As shown, a textile printing and dyeing drying device of the present invention includes a water tank 1, a heating tube 2 and a temperature controller 3 installed inside the water tank 1, a water pump 4 and an air pump 5 installed outside the water tank 1, a water delivery pipe 6 connected to the output end of the water pump 4, an input end of the air pump 5 connected to the water tank 1, and an air delivery pipe 7 connected to the output end of the air pump 5.

[0034] A drying chamber 8 is installed on the top of the water tank 1. The drying chamber 8 is provided with an inlet 9, an outlet 10 and an exhaust pipe 11. The inlet 9 and the outlet 10 are symmetrically arranged on both sides of the drying chamber 8. The exhaust pipe 11 is located on the side of the drying chamber 8. The inlet 9 and the exhaust pipe 11 are not on the same side. The drying chamber 8 is equipped with a contact drying mechanism 12 and a hot air drying mechanism 13.

[0035] The contact drying mechanism 12 includes two first telescopic cylinders 121 symmetrically installed in the drying chamber 8. Each of the upper and lower first telescopic cylinders 121 has a movable support 122 connected to its output end. Each of the upper and lower movable supports 122 has a mounting bracket 123 slidably mounted on it. Each of the upper and lower mounting brackets 123 is connected to a screw 124, which slidably matches the movable support 122. A spring 125 is installed between the mounting bracket 123 and the movable support 122, and the spring 125 is sleeved on the outside of the screw 124. 4. An adjusting nut 126 is threadedly connected to the contact roller 127, which is rotatably mounted on the mounting bracket 123. The contact roller 127 is hollow inside. Water inlet hole 128 and water outlet hole 129 are respectively provided at both ends of the contact roller 127. Water inlet collar 1210 and water outlet collar 1211 are rotatably mounted on the contact roller 127 at the corresponding positions of water inlet hole 128 and water outlet hole 129. The input end of water inlet collar 1210 is connected to water supply pipe 6, and the output end of water outlet collar 1211 is connected to return water pipe 14. The output end of return water pipe 14 is connected to water tank 1.

[0036] The hot air drying mechanism 13 includes two second telescopic cylinders 131 installed symmetrically in the drying chamber 8. The output ends of the two second telescopic cylinders 131 are connected to air chambers 132. The air chambers 132 are provided with exhaust grooves 133. Water-absorbing cotton 134 is placed inside the air chambers 132. The input end of the air chambers 132 is connected to the air supply pipe 7.

[0037] In this embodiment, the textile is introduced from the inlet 9, passes between the upper and lower contact rollers 127 and the upper and lower air chambers 132, and is drawn out from the outlet 10. During the subsequent drying process, the textile is continuously moved. Further, the continuous movement of the textile can be achieved by using a winding mechanism in the prior art.

[0038] In the continuous production process of the textile, the liquid in the heating pipe 2 inside the water tank 1 is heated. The heating power of the heating pipe 2 is adjusted according to the feedback temperature of the temperature controller 3. Then, the water pump 5 operates to send the heated liquid into the water delivery pipe 6, and then into the upper and lower water inlet sleeves 1210. The water inlet sleeves 1210 are rotating structures that do not interfere with the rotation of the contact rollers 127. At the same time, the water inlet holes 128 allow the liquid to enter the contact rollers 127. Under the effect of heat transfer, the contact rollers 127 are heated. The upper and lower first extension cylinders 121 operate to drive the upper and lower contact rollers 127 to contact the upper and lower surfaces of the textile. The upper and lower first extension cylinders 121 can be used with textiles of any thickness, ensuring adaptability. Under the effect of heat, the textile is contact-dried. The contact rollers 127 can also have an effect similar to an iron, improving the texture of the textile. Subsequently, the liquid passes through the water outlet sleeve 1211 and returns to the water tank 1 through the water return pipe 14, achieving recycling. During contact, the spring 125 ensures good contact between the contact roller 127 and the textile. The adjusting nut 126 adjusts the extension distance of the spring 127 to ensure the contact effect.

[0039] After the textile is contact-dried, it passes between the upper and lower air chambers 132. The air pump 5 operates to send the hot air generated by heating the liquid in the water tank 1 into the air chamber 132 through the air delivery pipe 7. The hot air is discharged from the air outlet groove 133 of the air chamber 132 to dry the textile by hot air. The water-absorbing cotton 134 reduces the water carried by the discharged gas, preventing the drying effect from being affected. Moreover, under the blockage of the water-absorbing cotton 134, the hot air is not easily concentrated in one point and discharged from the air outlet groove 133, but is more evenly discharged from the air outlet groove 133. The hot air also collects in the drying chamber 8, causing the entire drying chamber 8 to heat up. The temperature of the hot air is affected by the hot water, improving the drying efficiency. The hot air can be discharged through the exhaust pipe 11 for collection or returned to the water tank 1. It should be noted that the water-absorbing cotton 134 has the characteristics of shape change under extrusion and expansion, and can withstand a certain amount of pulling. When the internal water-absorbing cotton 134 needs to be replaced, the water-absorbing cotton 134 in the air chamber 132 is directly extracted from the air outlet groove 133, and then a new water-absorbing cotton 134 is extruded and placed into the air outlet groove 133. Of course, the specifications of the water-absorbing cotton 134 in the normal state should be adapted to the air chamber 132.

[0040] The installation of the temperature control meter 3 can detect the temperature of the hot water used for heat transfer in real time, and the heating power of the heating pipe 2 can be controlled according to the temperature-sensitive characteristics of different fibers (such as cotton and chemical fibers), so as to change the water temperature in the water tank 1, and then control the temperature of the contact roller 127, so that the contact of the contact roller 127 will not damage the textile, and the temperature of the subsequent hot air is also controlled.

[0041] In summary, on the basis of the traditional hot air drying, the contact type drying is added, and during the drying process, the continuous production of the textile can be ensured.

[0042] Example two:

[0043] As shown in Figure 2 , Figure 3 , the water inlet sleeve ring 1210 and the water feeding pipe 6 are connected by a hose 15, and the water outlet sleeve ring 1211 and the water return pipe 14 are also connected by a hose 15.

[0044] In this embodiment, the arrangement of the hose 15 ensures that when the upper and lower moving supports 122 move, the water feeding pipe 6 will not be pulled, ensuring the normal operation of water feeding.

[0045] Example three:

[0046] As shown in Figure 5 , the water inlet sleeve ring 1210 and the water outlet sleeve ring 1211 are both installed with waterproof bearings 16.

[0047] In this embodiment, the characteristics of the waterproof bearings 16 ensure the normal rotation of the contact roller 127 in the water inlet sleeve ring 1210 and the water outlet sleeve ring 1211, and the liquid will not flow out, ensuring that the liquid can enter the contact roller 127 from the water inlet hole 128.

[0048] Example four:

[0049] As shown in Figure 2 , the two side walls inside the drying chamber 8 are provided with limiting grooves 17, and the moving supports 122 and the air chambers 132 are slidingly installed in the corresponding limiting grooves 17.

[0050] In this embodiment, the movement of the moving supports 122 and the air chambers 132 is limited in direction, ensuring that the movement of the moving supports 122 and the air chambers 132 is horizontal, and the cooperation with the textile is good.

[0051] Example five:

[0052] As shown in Figure 2 , the output end of the air pump 5 is connected with an air-liquid separation chamber 18, and the output end of the air-liquid separation chamber 18 is communicated with the air feeding pipe 7.

[0053] In this implementation case, since the hot air is generated from liquid, it will contain moisture to a certain extent. The gas-liquid separation chamber 18 is used to separate the moisture and gas, ensuring the purity of the hot air and preventing it from affecting the quality of the textiles during hot air drying.

[0054] Example 6:

[0055] like Figure 3 As shown, the temperature controller 3 is equipped with a basic sensing unit, including a temperature sensing element and a signal transmission structure. The temperature controller 3 is also equipped with a control and output module, including a control circuit and an output interface.

[0056] In this embodiment, the temperature controller 3 accurately captures temperature changes through a temperature sensing element, and the control module stably outputs commands. Combined with an adaptive installation structure, it ensures physical environment compatibility. Furthermore, in the temperature sensing element, a bimetallic strip (such as a metal stack with different coefficients of thermal expansion) or a semiconductor sensor (such as a thermistor) serves as the core temperature sensing component and must have linear temperature response characteristics. In the signal transmission structure, mechanical temperature controllers require a precision transmission mechanism (gears / levers) to convert the deformation of the temperature sensing element into pointer displacement, while digital temperature controllers require an analog-to-digital converter circuit to convert analog signals into digital signals for output. In the control circuit, a proportional-integral (PI) algorithm module is integrated to achieve dynamic temperature adjustment. In the output interface, the relay output is adapted for ON / OFF control scenarios (such as heater start / stop) and must match the load power (≤10A).

[0057] It should be noted that the technology of temperature controller 3 is already mature, and it is not difficult for technicians in related fields to think about and understand how to use and install it. Signal acquisition, data processing and command issuance can already be integrated into temperature controller 3 in existing technologies. For example, the Bihe LC-215B+ temperature difference controller, which can be purchased directly on the market, can be installed and used immediately.

[0058] Furthermore, before changing and debugging different fiber production processes or when adjusting the contact temperature, the water temperature inside water tank 1 must be set. It is easy for technical personnel in the relevant field to understand that the equipment should not be put into operation before the required water temperature is met.

[0059] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
