Description

Technical Field

[0001] This utility model relates to the field of polyester-cotton fabric production technology, and in particular to a drying device for polyester-cotton fabric production. Background Technology

[0002] Polyester-cotton grey fabric is a raw, undyed fabric made from a blend of polyester (polyester fiber) and cotton fiber, typically 65% ​​polyester and 35% cotton. It combines the high strength and wrinkle resistance of polyester with the moisture absorption and breathability of cotton. The grey fabric is naturally colored (pale yellow or off-white), with a rough surface and impurities such as cotton seed hulls. This type of fabric requires subsequent treatments such as desizing, scouring, and bleaching before it can be dyed or printed. It is widely used in the production of shirts, workwear, and home textiles. Its advantages include low cost and high durability, but it may feel slightly rough against the skin, making it suitable for everyday textiles where comfort and durability are both important.

[0003] In the existing technology, most polyester-cotton fabric drying devices use single-sided hot air heating or static drying ovens, which makes it difficult to dry the front and back sides of the fabric evenly at the same time, resulting in low drying efficiency and uneven drying. At the same time, traditional equipment usually does not integrate a winding function, and after drying, it needs to be manually transferred to a separate winding machine, which not only increases the operation steps, but may also cause fabric wrinkles or contamination during the handling process, affecting the quality of finished products and production efficiency. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-4 This utility model provides a drying device for producing polyester-cotton fabric, including a drying box 1. Fabric troughs 4 are provided at the middle of both outer ends of the drying box 1. Guide rollers 3 are rotatably connected to both inner ends of the drying box 1. A mounting frame 16 is fixedly connected to the rear end of the drying box 1. A heating box 17 is fixedly connected to the top of the mounting frame 16. An air inlet pipe 18 is provided through the rear end of the heating box 17. The cooperation between the guide rollers 3 and the fabric troughs 4 enables stable conveying of the polyester-cotton fabric, ensuring the flatness of both sides of the fabric during conveying. A fan assembly and heating elements are installed inside the heating box 17. The fan is driven by a motor to blow air inwards, and the heating elements heat the air, ensuring that hot air enters the drying box 1 to quickly dry the polyester-cotton fabric.

[0027] The drying chamber 1 has guide plates 2 fixedly connected to both the upper and lower ends of its inner side. The other end of the air inlet pipe 18 passes through and connects to the interior of the guide plate 2. Several nozzles 12 are installed inside the guide plate 2. The heating chamber 17 has a mounting groove at the other end opposite the air inlet pipe 18. A filter screen 19 is installed inside the mounting groove. When the fan assembly inside the heating chamber 17 is started, outside air is sent into the heating chamber 17 by the fan. The heating pipe inside the heating chamber 17 can heat the air, so that the hot air enters the interior of the two sets of guide plates 2 through the air inlet pipe 18 and is sprayed outward through the nozzles 12 at both ends, so as to evenly dry both sides of the polyester-cotton fabric and ensure the drying efficiency of the entire device. The filter 19 intercepts dust and impurities in the air, preventing contamination of the polyester-cotton fabric. Furthermore, the jet assembly in this device is installed at both ends, allowing for uniform drying of both sides of the fabric. To prevent lint from clogging the nozzle 12, a filter is installed inside the nozzle 12. The fan assembly is installed inside the heating chamber 17, with its air inlet facing the mounting slot (i.e., the filter installation position). This ensures that the intake air is filtered first, driving outside air through the filter 19 into the heating chamber. The heated air is then pressurized and transported to the guide plate 2 via the air inlet pipe 18. The heating assembly is an electric heating element (such as a finned heating element or a stainless steel heating element), installed inside the heating chamber 17 on the air outlet side of the fan assembly (i.e., the air is heated after passing through the fan). This heats the air supplied by the fan, generating hot air at the required temperature.

[0028] Limiting grooves 21 are provided at the upper and lower ends of the mounting slot. Limiting blocks 20 are fixedly connected to the upper and lower ends of the filter screen 19. The limiting blocks 20 and the limiting grooves 21 correspond to each other. A connecting groove 24 is provided at the outer end of the heating box 17. A spring 23 is fixedly connected to one end of the inner side of the connecting groove 24. A positioning block 22 is fixedly connected to the other end of the spring 23. The positioning block 22 is installed through the inside of the limiting groove 21. A positioning groove is provided inside the limiting block 20. The positioning block 22 and the positioning groove correspond to each other. A sliding rod 13 is fixedly connected to both ends of the inner side of the limiting groove 21. The positioning block 22 is slidably connected to the sliding rod 13. When the filter screen 19 needs to be disassembled and replaced, the positioning block 22 is pulled outward first. Under the action of the spring 23, the positioning block 22 can be driven to retract into the connecting groove 24. At this time, the positioning block 22 leaves the inside of the positioning groove. The staff can directly remove the filter screen 19, thereby completing the quick disassembly and replacement of the filter screen 19.

[0029] A motor 9 is fixedly connected to one end of the outer side of the drying chamber 1. A slot 8 is opened at the end of the drying chamber 1 near the motor 9. A double-acting screw 7 is rotatably connected inside the slot 8. The output end of the motor 9 is fixedly connected to the double-acting screw 7. Two connecting brackets 6 are threaded onto the double-acting screw 7. A motor 11 is fixedly connected to the outer end of the left connecting bracket 6. A rotating shaft 14 is provided inside the output end of the motor 11, passing through the connecting bracket 6. A rotating shaft 14 is also rotatably connected inside the right connecting bracket 6. A winding roller 15 is installed inside the rotating shaft 14. A positioning bolt 10 is threadedly connected to the rotating shaft 14 and the winding roller 15. A slide rod is fixedly connected to the outer end of the drying chamber 1. 5. Both connecting frames 6 are slidably connected to slide rod 5. After drying and winding are completed, tighten the positioning bolt 10 to loosen the two ends of the rotating shaft 14 and the winding roller 15. Start motor 9 to drive the bidirectional screw 7 to rotate. Under the action of the threaded engagement, the two connecting frames 6 can move relative to each other and gradually move away from each other. The operator can directly remove the winding roller 15 from the connecting frame 6 and replace it. Secondly, an exhaust port is opened at the top of the drying box and connected to a simple air duct. The humid air in the box is continuously discharged through the slight positive pressure generated by the fan assembly or natural convection to avoid moisture accumulation that leads to a decrease in drying efficiency or condensation dripping that contaminates the fabric.

[0030] Working principle: During use, the operator passes the polyester-cotton fabric through the fabric trough 4 and guide roller 3 in sequence, winding it onto the take-up roller 15. Then, the door is closed, and motor 11 is started to slowly roll the polyester-cotton fabric. Subsequently, the fan assembly inside the heating chamber 17 is activated, and outside air is sent into the heating chamber 17 through the fan. The heating pipe inside the heating chamber 17 heats the air, causing the hot air to enter the two sets of guide plates 2 through the air inlet pipe 18 and be sprayed outward through the nozzles 12 at the upper and lower ends, thus heating the polyester-cotton fabric. Both sides are dried evenly to ensure the drying efficiency of the entire device. After drying and winding, the positioning bolts 10 are turned to loosen the two ends of the rotating shaft 14 and the winding roller 15. The motor 9 is started to drive the bidirectional screw 7 to rotate. Under the action of the threaded engagement, the two connecting frames 6 can move relative to each other and gradually move away from each other. The operator can directly remove the winding roller 15 from the connecting frame 6 and replace it. This device integrates drying and winding, which can greatly improve the processing efficiency of polyester-cotton fabric.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
