Description

Technical Field

[0001] The utility model relates to the technical field of cloth printing and dyeing, in particular to high-yield double-sided drying and printing and dyeing integrated equipment. Background Art

[0002] In this process, "double-sided" refers to treating both the front and back sides of the fabric, while "drying" involves using specialized equipment and conditions to remove excess moisture or solvent from the fabric during the printing process, accelerating the curing of the dyes and fixing the colors. This printing and dyeing method offers several significant advantages. For example, it ensures that the printed colors adhere more evenly and firmly to the fabric, maintaining consistent color and pattern on both sides. Double-sided drying also helps improve printing and dyeing efficiency and reduce production cycle times.

[0003] Taking common cotton fabrics as an example, after double-sided drying and dyeing, their color vividness and washability are improved. In actual production, different fabric materials and printing and dyeing agents may require adjustments to parameters such as drying temperature, time, and wind speed to achieve the best printing and dyeing results.

[0004] The current printing and dyeing equipment is still lacking in the adjustment of printing and dyeing effects, as well as the uniformity and consistency of drying, and needs further improvement and optimization. Utility Model Content

[0039] A drying partition plate 103 is fixed in the main housing 10 of the device, and the drying partition plate 103 has through holes 104 for printing and dyeing materials on both sides;

[0040] The printing and dyeing mechanism 20 includes two sets of printing and dyeing roller shaft groups 21 rotatably connected to the main housing 10 of the device.

[0041] like Figure 2 As shown, the printing and dyeing roller group 21 is connected to the inner wall of the equipment main body shell 10 through the printing and dyeing offset mechanism 23. The printing and dyeing offset mechanism 23 includes a plurality of printing and dyeing offset support slides 231 fixed on the inner wall of the equipment main body shell 10 and extending in the vertical direction.

[0042] The drying mechanism 30 includes two drying mechanism support plates 31 fixed in the device main body housing 10 and arranged horizontally. A plurality of eddy current drying arrays 32 are fixed on one side of the drying mechanism support plates 31 close to each other.

An electric throttle valve 335 is provided at each end of the heating connecting pipe 333.

[0047] Example 2:

[0048] On the basis of Example 1, Figure 1 As shown, a printing and dyeing preheating mechanism 11 is provided in the main housing 10 of the device. Figure 3 As shown, the printing and dyeing preheating mechanism 11 includes two preheating mechanism support plates 111 fixed in the main body shell 10 of the equipment and arranged horizontally. A plurality of electric heating plates 112 are fixed on one side of the preheating mechanism support plates 111 close to each other, and a plurality of heat radiation reflecting plates 113 are fixed between two adjacent electric heating plates 112.

[0049] Example 3:

[0050] On the basis of Example 2, Figure 1 As shown, a printing and dyeing ventilation mechanism 22 is provided in the main housing 10 of the device. Figure 4 As shown, the printing and dyeing ventilation mechanism 22 includes a ventilation guide column 221 fixed in the main housing 10 of the equipment and arranged horizontally. A negative pressure conduction shell 222 extending parallel to its axis is fixed to the side of the ventilation guide column 221. A plurality of negative pressure conduction pipes 223 connected to the interior of the negative pressure conduction shell 222 are fixed to the lower side of the negative pressure conduction shell 222. The negative pressure conduction pipes 223 extend circumferentially along the ventilation guide column 221.

[0051] A negative pressure exhaust pipe 224 is fixed on the negative pressure conducting shell 222 and is connected to the interior thereof. The negative pressure exhaust pipe 224 is connected to an exhaust fan, and the negative pressure exhaust pipe 224 is connected to the input end of the exhaust fan.

[0052] In the actual application process of the present invention, the cloth to be printed and dyed enters the interior of the main housing 10 of the device through the material input opening 101, and is printed and dyed on both sides of the cloth by the printing rollers 211 in the two sets of printing rollers 21;

[0053] The heated matching roller 212 is used to heat the fabric to promote the full combination of dye and fiber and color fixation;

[0054] The inner wall of the heating and matching roller 212 is provided with multiple electric heating plates, which are used to evenly heat the heating and matching roller 212, and the heating and matching roller 212 then transfers the heat to the fabric;

[0055] In one group of printing and dyeing roller shafts 21 near the material input opening 101, the printing and dyeing roller shaft 211 is located above the heating and matching roller shaft 212, while in the other group of printing and dyeing roller shafts 21, the printing and dyeing roller shaft 211 and the heating and matching roller shaft 212 are inverted.

[0056] During the dyeing process, the dyeing preheating mechanism 11 is used to preheat the fabric to promote the full bonding of the dye and the fiber and the color fixation. After entering the material input opening 101, the fabric first passes between the two preheating mechanism support plates 111. Each electric heating plate 112 is energized and heated. The heat generated by the electric heating plates 112 is transferred to the fabric in the form of thermal radiation. Each thermal radiation reflector 113 can more evenly reflect the thermal radiation energy to the fabric to achieve preheating of the fabric.

[0057] When the cloth passes through the printing and dyeing ventilation mechanism 22, the printing and dyeing ventilation mechanism 22 is used to quickly dry the cloth surface in advance. The negative pressure exhaust pipe 224 is connected to an exhaust fan, which is used to exhaust air inside the negative pressure conductive shell 222. Under the action of negative pressure, the air near the cloth continuously flows into the negative pressure conductive shell 222 through the negative pressure conductive pipe 223.

[0058] During the circulation of air near the fabric, due to the viscosity of the fluid, the airflow will circulate along the surface of the ventilation guide column 221. The airflow generated under the action of negative pressure will accelerate the circulation of air on the fabric surface, thereby achieving rapid drying of the fabric surface.

[0059] The fabric then passes through the dye material perforations 104 and passes through the drying mechanism 30. Hot air is continuously ejected from the drying hot air nozzles 320 in each eddy current drying array 32, causing the hot air to flow over the fabric surface and then be exhausted through the drying return pipe 322.

[0060] The drying return pipe 322 is connected to an exhaust fan, which is used to extract the hot air after drying the fabric through the drying return pipe 322;

[0061] Multiple eddy current drying arrays 32 form several hot air eddies on the surface of the fabric, drying the fabric under the dual effects of heat energy and airflow;

[0062] The mixed hot air delivery mechanism 33 is used to continuously deliver hot air to each drying delivery pipe 321. The gas conveyor 332 continuously delivers air to the mixed delivery pipe 331. Part of the air flows through the heating connecting pipe 333 and then merges into the mixed delivery pipe 331. The opening of the electronically controlled throttle valve 335 is controlled to adjust the air flow through the heating connecting pipe 333. The electric heating wire 334 is energized to generate heat, and the electric heating wire 334 is used to heat the air flowing through the heating connecting pipe 333, thereby adjusting the air flow through the heating connecting pipe 333 and thus adjusting the temperature of the merged air.

[0063] The relative position between the two printing roller groups 21 is adjusted by the printing and dyeing offset mechanism 23, thereby adjusting the traction route of the cloth to achieve various printing and dyeing effects. The servo motor drives the printing and dyeing offset support slider 232 together with the roller group connecting plate 233 to move along the printing and dyeing offset support slide rail 231. The roller group connecting plate 233 drives the printing and dyeing roller 211 and the heating matching roller 212 in the printing and dyeing roller group 21 to move synchronously, and adjusts the relative position of the two printing and dyeing roller groups 21 in the vertical direction. When the cloth is pulled around the printing and dyeing roller 211, there are different contact areas between the cloth and the printing and dyeing roller 211, and the amount of dye applied to the cloth is also different.

[0064] It should be noted that the electric heating plate 112, thermal radiation reflecting plate 113, gas conveyor 332, electric heating wire 334, and electronically controlled throttle 335 used in this application are all based on existing technologies and are not specifically limited here. Those skilled in the art can choose them according to their needs as long as they can implement the technical solution of this application.
