Description

Technical Field

[0001] The utility model relates to a spinning device, in particular to a spinning device with a filament side air blowing device. Background Art

[0002] In the process of spinning production, the function of the cooling air blowing device is to cool the liquid filaments that have been subjected to high temperature and high pressure and ejected from the spinneret; the cooling air blowing device is divided into an annular air blowing device and a side air blowing device. When using the side air blowing device, in order to achieve a better cooling effect, an auxiliary cooling device is often added near the side air blowing device.

[0003] The existing auxiliary cooling device, as disclosed in CN 204550811U, has the following problems:

[0004] 1. Several square pipes are installed in parallel at intervals between adjacent flow stabilizing plates. The square pipes penetrate in the front-back direction of the flow stabilizing plates, and the interval between the flow stabilizing plate layers is blocked by them, preventing the cooling air from flowing left and right, which affects the uniformity of the cooling air; each square pipe is an independent pipeline and is not easy to clean;

[0005] 2. Generally speaking, the higher the overall height of the auxiliary cooling device and the smaller the layer spacing between the flow stabilizing plates, the better the rectifying effect on the cooling air. However, for some less sensitive filament varieties, since they are less affected by the disturbance of the cooling air, they do not require a particularly high height and a particularly small layer spacing. The overall height of the current auxiliary cooling device and the layer spacing between the flow stabilizing plates are not adjustable, and it is impossible to achieve an optimal balance between the rectifying effect and the cost. Content of the Utility Model

[0006] The purpose of the utility model is to overcome the problems existing in the prior art and provide a spinning device with a filament side air blowing device, which can achieve an optimal balance among the rectifying effect, the maintenance effect and the cost.

[0007] To solve the above technical problems, a spinning device with a filament side air blowing device provided by the utility model has a cooling passage located below the spinneret. A side air blowing device is arranged on the inner side of the cooling passage. The filaments are extruded from the spinneret and pass through the cooling passage. The side air blowing device blows cooling air towards the filaments located in the cooling passage. An auxiliary cooling device is arranged on the inner side and / or the outer side of the cooling passage. The auxiliary cooling device has multiple layers of horizontally arranged flow stabilizing plates. A threaded rod passes through the multiple flow stabilizing plates. Adjacent flow stabilizing plates are separated by a spacer. The spacer is sleeved on the threaded rod.

[0008] Further, the spacer is designed as a cylindrical sleeve.

[0009] Further, an arc-shaped concave portion is provided on one side of the multi-layer horizontally arranged flow stabilizing plates, and the vertically adjacent concave portions form a spinning channel.

[0010] Further, a diversion channel is formed between adjacent flow stabilizing plates.

[0011] The technical solution of the present utility model has the following remarkable beneficial effects:

[0012] By improving the existing auxiliary cooling device, the overall height and layer spacing of the auxiliary cooling device can be adjusted, and it is easier to clean, achieving a better balance among the rectification effect, maintenance effect and cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In the following description of the present utility model, the orientation or positional relationships indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating that the device must have a specific orientation.

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below with reference to specific illustrations.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used herein in the description of this utility model are for the purpose of describing specific embodiments only and are not intended to limit this utility model.

[0021] The Figure 1 , Figure 2 , Figure 3 and Figure 4 directions shown are defined as the front-back, left-right, up-down directions, and the following description will be made accordingly.

[0022] Figure 1 FIG. is a partial cross-sectional view of the spinning device 1 with the auxiliary cooling device 3 installed outside the cooling channel 7. The shown spinning device 1 has a spinneret plate 6 at the top, and the filament Y is extruded from the spinneret plate 6. The metering pump and the melt distribution pipe above the spinneret plate 6 are not shown in the drawings. A cooling channel 7 is provided below the spinneret plate 6, which provides space for the installation of the side blowing device 2. The side blowing device 2 is provided on the inner side of the cooling channel 7. The filament Y passes through the cooling channel 7 after being extruded from the spinneret plate 6. The side blowing device 2 blows cooling air towards the filament Y located in the cooling channel 7, and the blown cooling air is easily driven by the filament Y in the traveling direction of the filament Y, resulting in different cooling effects on the filament Y on the side close to the side blowing device 2 and the filament Y on the side far from the side blowing device 2. Therefore, according to the actual situation, the auxiliary cooling device 3 can be provided on the inner side of the cooling channel 7, or the auxiliary cooling device 3 can be provided on the outer side of the cooling channel 7, or the auxiliary cooling device 3 can be provided on both the inner side and the outer side of the cooling channel 7 at the same time to guide the cooling air blown by the side blowing device 2 and discharge it from the auxiliary cooling device 3, so that the filament Y is cooled evenly and a good cooling effect is achieved.

[0023] Figure 2 is a side view of the auxiliary cooling device 3 of this utility model, Figure 3 is a top view of the auxiliary cooling device 3, Figure 4 is a perspective view of the auxiliary cooling device 3. Refer to Figures 2 to 4, the auxiliary cooling device 3 includes a plurality of horizontally arranged flow stabilizing plates 3.3. A threaded rod 3.1 passes through the plurality of flow stabilizing plates 3.3. Adjacent flow stabilizing plates 3.3 are separated by a spacer 3.2, and the spacer 3.2 is sleeved on the threaded rod 3.1. In this embodiment, the spacer 3.2 is designed as a cylindrical sleeve, but the present application is not limited thereto, and it can also be designed as a component of other shapes. An arc-shaped concave portion is provided on one side of the plurality of horizontally arranged flow stabilizing plates 3.3. The vertically adjacent concave portions form a spinning channel 4 to facilitate surrounding the passage of the filament Y. A diversion channel 5 is formed between adjacent flow stabilizing plates to guide and discharge the cooling air blown out by the side blowing device 2, and to make the filament Y be cooled evenly, achieving a good cooling effect.

[0024] During use, the layer spacing between two adjacent flow stabilizing plates 3.3 can be adjusted by replacing the spacers 3.2 with different heights, and the overall height of the auxiliary cooling device 3 can be adjusted by replacing the threaded rods 3.1 with different lengths. For some filament varieties that are not very sensitive to the disturbance of the cooling air, spacers 3.2 with a higher height and threaded rods 3.1 with a shorter length can be selected to achieve a better balance among the rectifying effect, maintenance effect, and cost. Compared with the prior art, using the spacer 3.2 makes the whole structure similar to being completely hollowed out, with little blockage to the left and right flow of the cooling air and little impact on the uniformity of the cooling air. Compared with the square tubes used in the prior art that are prone to accumulating dust and dirt, the spacer 3.2 is easier to clean.
