Description

Technical Field

[0001] The present application relates to the field of wool sliver spinning, and in particular to a yarn bundle drying device. Background Art

[0002] A tow is a basically untwisted long chemical fiber bundle that is made up of a large number of continuous filaments that are used to cut into short fibers or to make chemical fiber strips through the stretch-cutting method. After chemical fiber spinning, a considerable number of single filaments are gathered into a tow.

[0003] In the wool spinning process, the bundled filaments need to go through a drying process to ensure that the filaments have a suitable moisture content and temperature. In the prior art, the filaments are usually directly sent into the oven, and the filaments are transported by the conveying rollers provided in the oven, and the filaments passing through the oven are dried by the hot air in the oven during the transportation process. However, the above scheme has the following defects: First, due to the setting of the conveying rollers, there are drying dead corners when the filaments pass through the oven, resulting in that some filaments cannot be effectively dried, which greatly affects the quality of the output filaments; second, the conveying distance of the filaments in the oven is limited by the length of the oven, resulting in a shorter residence time of the filaments in the oven, which greatly affects the drying effect of the filaments.

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] See also Figure 1 As shown, a tow drying device is shown, which includes a horizontally arranged box body 1, a wire inlet 11 and a wire outlet 12 opened at both ends of the box body 1 in the length direction, three conveying roller groups 2 are arranged at intervals in the box body 1 along its length direction, and a first gap 3 is provided between two adjacent conveying roller groups 2, and a drying assembly 4 is arranged on both sides of the box body 1 in the height direction, and the drying assembly 4 includes a first hot air pipe 41 extending along the length direction of the box body 1, an electric hot air blower 42 connected to the first hot air pipe 41, and a plurality of first air outlet holes 43 opened on the first hot air pipe 41, and the first hot air pipe 41 is also connected to two second hot air pipes 44, and the second hot air pipe 44 is provided with a plurality of second air outlet holes 45, and the four second hot air pipes 44 constituting the two drying assemblies 4 are respectively accommodated in the four first gaps 3 in a one-to-one correspondence. Among them, the plurality of first air outlet holes 43 are arranged at intervals around the circumference of the first hot air pipe 41, and the plurality of second air outlet holes 45 are arranged at intervals around the circumference of the second hot air pipe 44.

[0033] When the filament bundle passes through the three conveying roller groups 2, the two first hot air pipes 41 dry the filament bundle from the upper and lower sides respectively, and the two second hot air pipes 44 connected to each first hot air pipe 41 can extend into the corresponding first gap 3 from the upper and lower sides respectively and dry the filament bundle from the left and right sides of the filament bundle, thereby eliminating drying dead corners and improving the drying effect of the filament bundle.

[0034] In this embodiment, the four second hot air pipes 44 constituting the two drying components 4 correspond to each other in pairs, and the two corresponding second hot air pipes 44 are arranged in an up-down staggered manner. The length direction of the second hot air pipe 44 is the same as the conveying direction of the tow between two adjacent conveying roller groups 2. In this way, the two corresponding second hot air pipes 44 can approach the tow from both sides in the thickness direction of the tow and dry the tow, further improving the drying effect of the tow.

[0035] In this embodiment, second gaps 5 are formed between the three conveying roller groups 2 and the two ends of the box body 1 in the length direction, and the drying assembly 4 also includes a third hot air pipe 46 connected to the end of the first hot air pipe 41, and a plurality of third air outlets 47 opened on the third hot air pipe 46. The two third hot air pipes 46 constituting the two drying assemblies 4 are respectively accommodated in the two second gaps 5 in a one-to-one correspondence. The third hot air pipe 46 can effectively dry the front and rear ends of the tow, further eliminating the drying dead angle. Among them, the third hot air pipe 46 is perpendicular to the first hot air pipe 41, and the plurality of third air outlets 47 are arranged around the circumference of the third hot air pipe 46.

[0036] In this embodiment, the extension direction of the conveying roller group 2 is the same as the width direction of the box body 1, the drying component 4 is movably arranged along the width direction of the box body 1, and the filament drying device also includes two driving components 6 respectively used to drive the two drying components 4 to move.

The two conveying rollers 21 arranged up and down can effectively increase the movement stroke of the tow in the box 1, thereby improving the drying effect of the tow.

[0041] The conveying roller 21 is hollow, and the two axial ends of the conveying roller 21 are respectively provided with medium inlet and outlet 22 for passing heat exchange medium. When the filament bundle is wound around the conveying roller 21, it can exchange heat with the roller surface of the conveying roller 21, further improving the drying effect of the filament bundle.
