Description

Technical Field

[0001] This utility model relates to the field of fabric processing technology, and in particular to a cooling device for processing raw fabric. Background Technology

[0002] Raw fabric is a semi-finished fabric in the textile industry that has not undergone dyeing and finishing processes. It is woven from undyed cotton yarn, linen yarn, or chemical fiber yarn. During the weaving process of raw fabric, heat accumulates due to mechanical friction and yarn tension. If it is not cooled in time, the internal thermal stress of the fibers may cause the fabric to deform or crack. Therefore, most common weaving processes include a cooling step, which can eliminate the internal stress of the fabric and thus ensure the quality of the finished raw fabric.

[0003] However, some cooling methods involve first unwinding the raw fabric by winding and unwinding it, then cooling it before winding it back up. While this method can achieve a cooling effect, it requires a temporary shutdown after each roll of raw fabric is cooled to replace the winding and unwinding sections. The time spent on replacements and restarting the machine after each replacement is considerable, which prevents the cooling efficiency from being improved.

[0004] Therefore, it is necessary to provide a new cooling device for processing raw fabric to solve the above-mentioned technical problems. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1-6 The raw fabric processing cooling equipment includes: a base 1, and a concave support frame 2 fixedly installed on the top of the base 1. Two U-shaped unwinding frames 3 are fixedly installed inside the concave support frame 2. U-shaped swivel grooves 4 are opened on both sides of the two U-shaped unwinding frames 3 to place the raw fabric rollers. Two winding mechanisms are provided above the base 1. The two winding mechanisms are adapted to the two U-shaped unwinding frames 3 respectively, so that two sets of raw fabric winding and unwinding mechanisms can be formed, which lays the foundation for the formation of two sets of alternating cooling operations in the following text.

[0023] Furthermore, in order to achieve comprehensive cooling of the raw fabric, a blower 12 is fixedly installed on the top of the base 1, and a ventilation main duct 13 is fixedly installed on its air inlet. A first air distribution duct 14, a second air distribution duct 15, and a third air distribution duct 20 are fixedly installed on the ventilation main duct 13. The first air distribution duct 14 is located below the second air distribution duct 15, and the third air distribution duct 20 is located between the first air distribution duct 14 and the second air distribution duct 15. Multiple first connecting pipes 16 are fixedly installed on the top of the first air distribution duct 14, and multiple second connecting pipes 17 are fixedly installed on the bottom of the second air distribution duct 15. The ends of the multiple first connecting pipes 16 and the multiple second connecting pipes 17 are all fixedly installed with first longitudinally placed... The pipe 18 has multiple first air nozzles 19 fixedly installed on each of the multiple first vertical pipes 18. The third air distribution pipe 20 has multiple third connecting pipes 21 and multiple fourth connecting pipes 22 fixedly installed on each of the multiple third connecting pipes 21 and multiple fourth connecting pipes 22. The ends of the multiple third connecting pipes 21 and multiple fourth connecting pipes 22 are all fixedly installed with second vertical pipes 23. Multiple second air nozzles 24 are fixedly installed on each of the multiple second vertical pipes 23. The first air nozzles 19 and second air nozzles 24 located below form a working relationship, while the first air nozzles 19 and second air nozzles 24 located above form a working relationship, thereby enabling them to cooperate with the two winding mechanisms.

[0024] In the above-mentioned method, each of the winding mechanisms includes a U-shaped winding frame 6. A drive shaft 7 and a driven shaft 8 are rotatably mounted on the inner walls of both sides of the U-shaped winding frame 6. Slots 9 are provided on the sides of the drive shaft 7 and driven shaft 8 that are close to each other. Connecting strips 10 are fixedly installed in both slots 9 by bolts. The same winding roller 11 is fixedly installed on the side of the two connecting strips 10 that are close to each other. A drive motor is fixedly mounted on one outer wall of the U-shaped winding frame 6, and its output shaft is fixedly connected to one end of the drive shaft 7. A cylinder is fixedly mounted on the other outer wall of the U-shaped winding frame 6. An arc-shaped damping plate is fixedly mounted on the output shaft of the cylinder. The arc-shaped damping plate is adapted to the driven shaft 8. When it is necessary to remove the winding roller 11 wrapped with white fabric, the cylinder is first activated, and the arc-shaped damping plate is used to lock the driven shaft 8, thus removing the winding roller 11 and preventing the driven shaft 8 from rotating.

[0025] In this method, in order to support the two winding mechanisms, a support side plate 5 is fixedly installed on the top of the base 1, and a frame strip is fixedly installed on the bottom of the winding mechanism. One side of the frame strip is fixedly connected to the support side plate 5, and the ventilation main pipe 13 passes through the support side plate 5 and the frame strip.

[0026] In this method, in order to make full use of the airflow and reduce energy consumption, a first electric air valve is provided on the first air distribution duct 14 and multiple third connecting pipes 21, and a second electric air valve is provided on the second air distribution duct 15 and multiple fourth connecting pipes 22. The first and second electric air valves can be opened and closed according to actual needs.

[0027] In this method, in order to form a conveying guide for the raw fabric, two U-shaped frames 25 are fixedly installed on the top of the base 1. Guide rollers are rotatably installed in both U-shaped frames 25. The corresponding two guide rollers are matched, and the raw fabric will be conveyed between the two guide rollers. In addition, three reinforcing plates are fixedly installed in the U-shaped frames 25 away from the blower 12. The ends of the first air duct 14, the second air duct 15 and the third air duct 20 are respectively fixedly connected to the three reinforcing plates.

[0028] The working principle of the white fabric processing cooling equipment provided by this utility model is as follows:

[0029] When it is necessary to cool the white fabric, first place both ends of a roll of white fabric to be cooled in the two U-shaped grooves 4 on the U-shaped unwinding frame 3 below, then take one side of the white fabric, pass it through the two corresponding guide rollers in one set, then through the two corresponding guide rollers in another set, and finally fix it on the corresponding take-up roller 11. At this time, the white fabric that is pulled out is between the corresponding first air nozzle 19 and the second air nozzle 24.

[0030] Subsequently, the first electric air valves on the first air duct 14 and multiple third connecting pipes 21 are opened directly, and the blower 12 is started. The blower 12 draws air and sprays it out through the corresponding first air nozzle 19 and second air nozzle 24, directly spraying it onto the white fabric to form cooling. Then, the corresponding drive motor is started, which can rotate the corresponding winding roller 11 to wind up the white fabric. During the winding process, the airflow sprayed by the first air nozzle 19 and second air nozzle 24 can accelerate the cooling speed of the white fabric.

[0031] During the cooling process described above, the worker can take out another white fabric roller to be cooled and install it in the U-shaped trough 4 on the upper U-shaped unwinding frame 3. Then, take one side of the white fabric and pass it through the two corresponding guide rollers in the same way as described above, and finally fix it on the corresponding take-up roller 11.

[0032] After the previous roll of raw fabric has cooled down, the first electric air valve can be closed, and the second electric air valves on the second air duct 15 and the fourth connecting pipe 22 can be opened. At this time, the airflow will be sprayed out from the corresponding first air nozzle 19 and second air nozzle 24 and sprayed onto the raw fabric above, thus continuing the cooling process. At the same time, the previous empty raw fabric roll and the take-up roll 11 containing the raw fabric are removed. During removal, the empty raw fabric roll is directly taken out from the U-shaped trough 4, and then the next raw fabric roll to be cooled is placed on top. Then, the output shaft of the corresponding cylinder is activated to extend, and its output shaft drives the arc The damping plate rises, tightly fixing the corresponding passive shaft 8. Then, the bolts on the connecting strips 10 on both sides of the corresponding take-up roller 11 are removed, allowing it to be disassembled. Then, the empty take-up roller 11 is taken out, and the two connecting strips 10 on it are inserted into the corresponding mounting slots 9 and fixed with bolts. This completes the replacement of the white fabric roller and the take-up roller 11. After the previous roll of white fabric has cooled down, the second electric air valve is closed, and the first electric air valve is opened to cool the next roll of white fabric. This process is repeated until all the white fabric rollers have cooled down.

[0033] Compared with related technologies, the white fabric processing cooling equipment provided by this utility model has the following beneficial effects:

[0034] This utility model provides a cooling device for processing raw fabric. Two sets of first longitudinal pipes 18 and two sets of second longitudinal pipes 23 can be installed through the first connecting pipe 16, the second connecting pipe 17, the third connecting pipe 21 and the fourth connecting pipe 22. Furthermore, through the two U-shaped unwinding frames 3 and the two sets of winding mechanisms, the previously cooled raw fabric can be removed while cooling a roll of raw fabric, and then the next roll of raw fabric to be cooled can be reinstalled. By controlling the opening and closing of the first electric air valve and the second electric air valve, two sets of alternating cooling processes can be formed, so that the cooling work can be carried out continuously without stopping, which greatly improves the cooling efficiency and makes full use of the time for changing the roll.
