Description

Technical Field

[0001] The utility model relates to the technical field of textile printing and dyeing machinery, in particular to a drum-type uniform heat conduction drying machine. Background Art

[0002] Printing and dyeing is a textile processing method, also a general term for pre-treatment, dyeing, printing, finishing, and washing processes. To support environmentally friendly printing and dyeing concepts and reduce waste gas emissions, existing printing and dyeing equipment generally uses rotary heating drums to dry, fix, or steam fabrics after pre-printing and dyeing. However, due to the short drying stroke, it can only be air-dried at high wind speeds. Excessive wind speeds can easily cause high wind pressure on the textile, affecting its structural strength. At the same time, the hot air blower is only installed on one side, so it can only dry on one side, resulting in less than ideal drying results.

[0003] This case was created to solve the above problems. Utility Model Content

[0020] The present invention will be further described in detail below through the accompanying drawings and examples.

[0021] like Figure 1-2As shown: A drum-type uniform heat conduction dryer, including multiple heating drums and guide rollers built into a conventional drying machine box 8, the cloth 7 is wound and passed out along the arrangement direction of the heating drums and guide rollers, wherein the heating drums and guide rollers are connected for use, the middle part of the guide roller is through, and multiple long grooves are opened on the guide roller along its length direction. Each long groove is connected to the middle part of the guide roller to serve as an air outlet, and hot air is introduced into one end of the guide roller (blown in by an external hot air blower) and can directly blow the upper and lower surfaces of the cloth 7.

[0022] It should be noted that the air outlet of the guide roller is changed according to the position of the guide roller, and a distance is left between the guide roller and the cloth 7 to prevent residual water on the cloth 7 from flowing into the air outlet and affecting the drying effect.

[0023] The guide roller and heating roller need to be matched in various ways, such as Figure 1 As shown in the figure, heating rollers 1 and guide rollers 4 of the same size are arranged alternately and adjacently on the same horizontal line. The lower side and side of heating roller 1 are connected to guide roller 2 2, and the lower side of adjacent guide roller 4 is connected to heating roller 2 5. The cloth 7 is wound around and contacts each heating roller 1 and heating roller 2 5 to achieve online heating. At the same time, guide roller 1 4 and guide roller 2 2 are respectively spaced apart from the cloth 7, and the air outlets of adjacent guide rollers 4 and guide roller 2 2 are respectively located on both sides of the cloth 7. Therefore, direct blowing on both sides of the cloth 7 can be achieved.

[0024] The method of winding the fabric 7 along the heating drum and guide rollers in sequence increases the drying process to a certain extent, which is more conducive to drying. At the same time, the hot air discharged from the guide roller outlet passes through the fibers and gaps in the heated textile fabric 7, effectively removing moisture from them, resulting in a relatively dry textile fabric 7.

[0025] As an improvement, since the modes of the above-mentioned heating roller and guide roller need to be switched, the production cost is higher and more complicated, so the heating roller and guide roller are improved and the arrangement method is improved. Figure 3 As shown, the two ends are conventional guide rollers 12, and the middle part is a guide roller three of the same size as the conventional guide roller 12, which has multiple long grooves opened laterally along its length direction, and hot air is introduced into one end of the guide roller three (blown in by an external hot air blower) and can blow directly onto the upper and lower surfaces of the cloth 7.

[0026] One side of each guide roller 3 is axially connected to a heating roller 2 5, wherein one of the two adjacent heating rollers 2 5 is located above the guide roller 3, and the other is located below the guide roller 3. The air outlet on the guide roller 3 on the lower side is inclined upward and is designated as the upper air outlet 3, while the air outlet on the guide roller 3 on the upper side is inclined downward and is designated as the lower air outlet 6.

[0027] See attached Figure 4 As shown (attached Figure 3A tube seat 9 is connected to one side of each guide roller 3, and adjacent tube seats 9 are connected by air pipes 10. A connector 11 is provided on the relatively central air pipe 10 for introduction into the output end of an external hot air blower.

[0028] The above description is based on the embodiments for inspiration. Through the above description, relevant personnel can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content of the specification, and its protection scope must be determined according to the scope of the claims.
