Description

Technical Field

[0001] This utility model relates to the field of chemical fiber equipment technology, and in particular to a total reflection side-blowing device. Background Technology

[0002] In the production of synthetic fibers, filaments require air cooling, and there are two cooling methods: side blowing and ring blowing. Side blowing has the advantage of a larger air volume and better cooling effect, making it suitable for producing coarse denier filaments; while ring blowing, with its circular airflow, provides uniform cooling, resulting in better filament evenness, making it suitable for producing fine denier, porous filaments. In actual production, because early production lines were mostly equipped with side blowing (ring blowing technology was developed later), using side blowing lines to produce fine denier filaments can lead to uneven airflow, resulting in poor filament evenness and uneven dyeing. Utility Model Content

[0003] The purpose of this invention is to provide a total reflection side-blowing device. By attaching rubber sheets, the cooling air can be reflected, making the cooling air more uniform, which can significantly improve the quality of chemical fiber products and reduce the cost of production line modification.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A total reflection side-blowing device includes two laminar flow elements arranged opposite each other, and each laminar flow element includes multiple grid plates evenly distributed in the vertical direction;

[0006] The outer laminar flow unit is covered with rubber. Cooling air is ejected from the inside of the inner laminar flow unit from the inside out. The air is rectified by multiple grids in the laminar flow unit. After passing through the yarn, the cooling air enters the outer laminar flow unit. Then, the rubber blocks and reflects the cooling air. The reflected cooling air is then blown back onto the yarn from other directions, thus achieving a similar effect to ring blowing. This improves the uniformity of yarn cooling and significantly enhances yarn quality, as evidenced by a significant decrease in the yarn evenness CV value, from 1.6 to 0.7.

[0007] The present invention is further configured such that the rubber sheet is detachably connected to the outer laminar flow device via adhesive tape, thereby facilitating the installation and removal of the rubber sheet. When side blowing is required, the rubber sheet can be removed; when a ring blowing effect is required, the rubber sheet is fixed to the outer laminar flow device with adhesive tape.

[0008] The present invention is further configured such that: the outer side of the outer laminar flower is formed with a wavy curved surface;

[0009] The rubber sheet is wavy and adheres to the wavy curved surface.

[0010] The rubber sheet is designed in a wavy shape, which allows for multi-directional reflection, resulting in better reflection and more even cooling airflow.

[0011] The present invention is further configured such that the rubber sheet is fixed on the corrugated retaining plate, and the retaining plate facilitates the shaping of the rubber sheet, thereby facilitating the installation of the rubber sheet onto the corrugated curved surface of the laminar flow device.

[0012] The present invention is further configured such that: multiple screws are fixed on the corrugated retaining plate, and top sleeves are screwed onto the screws. The top sleeves abut against the corresponding side plates of the chemical fiber equipment and are supported by the multiple top sleeves on the side plates. The top sleeves support the corrugated retaining plate through the screws. Rotating the top sleeves allows them to move on the screws, thereby allowing for spacing adjustment to meet different spacing requirements.

[0013] The present invention is further configured such that: a rubber head is provided on the outer side of the top sleeve, which can increase the frictional resistance between the top sleeve and the corresponding side plate of the chemical fiber equipment, and prevent it from slipping or loosening.

[0014] The outstanding effect of this utility model is:

[0015] Compared with existing technologies, by applying rubber sheets, the cooling air can be reflected, making the cooling air more uniform, which can significantly improve the quality of chemical fiber products and reduce the cost of production line transformation.

[0016] The rubber sheet is removable to meet the needs of different working conditions;

[0017] The wavy design of the rubber enhances the airflow reflection effect, further improving the cooling uniformity. Attached Figure Description

[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0023] The following is for reference Figures 1 to 3 The present invention will be described as follows: Example 1

[0024] A total reflection side blowing device includes two laminar flow elements 1 arranged opposite to each other, and each laminar flow element 1 includes multiple grid plates 11 evenly distributed in the vertical direction.

[0025] The outer laminar flow unit 1 is covered with rubber 2. Cooling air is sprayed from the inside of the inner laminar flow unit from the inside out. The air is rectified by multiple grids in the laminar flow unit. After passing through the filament, the cooling air enters the outer laminar flow unit. Then, the rubber 2 blocks and reflects the cooling air. The reflected cooling air is then blown back onto the filament 9 from other directions, thus achieving a similar effect to ring blowing. This improves the uniformity of cooling of the filament and significantly enhances the quality of the filament. This is reflected in the significant decrease in the filament evenness CV value, from 1.6 to 0.7.

[0026] The rubber sheet 2 is detachably connected to the outer laminar flow unit 1 via tape, which facilitates the installation and removal of the rubber sheet. When side blowing is required, the rubber sheet can be removed; when a ring blowing effect is required, the rubber sheet is fixed to the outer laminar flow unit with tape. Example 2

[0027] Based on Example 1, such as Figure 2 , Figure 3 As shown, the outer laminar flow device 1 has a wavy curved surface 12 formed on its outer side.

[0028] The rubber sheet 2 is wavy and is attached to the wavy curved surface 12.

[0029] The rubber sheet is designed in a wavy shape, which allows for multi-directional reflection, resulting in better reflection and more even cooling airflow.

[0030] The rubber sheet 2 is fixed on the corrugated retaining plate 3. The retaining plate facilitates the shaping of the rubber sheet, thereby making it easy to install the rubber sheet onto the corrugated curved surface of the laminar flow unit. Example 3

[0031] Based on Example 2, multiple screws 4 are fixed on the corrugated retaining plate 3, and top sleeves 5 are screwed onto the screws 4. The top sleeves abut against the corresponding side plates of the chemical fiber equipment and are supported by the multiple top sleeves on the side plates. The top sleeves support the corrugated retaining plate through the screws. Rotating the top sleeves can move the top sleeves on the screws, thereby adjusting the spacing to meet different spacing requirements.

[0032] The outer side of the top sleeve 5 is provided with a rubber head 51. By setting the rubber head, the frictional resistance between the top sleeve and the corresponding side plate of the chemical fiber equipment can be increased, preventing it from slipping or loosening.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model. These improvements and modifications assumed above should also be considered within the protection scope of the present utility model.
