Description

Technical Field

[0001] The utility model relates to the technical field of spinning equipment, in particular to a scraper for spinning equipment. Background Art

[0002] Viscose fiber is made of natural cellulose. It is made into cellulose xanthate through processes such as impregnation, aging and xanthation, and then dissolved in dilute alkali solution to make viscose stock solution, which is then filtered, degassed and spun. The viscose stock solution is sprayed into an acid bath whose main components are sulfuric acid and sodium sulfate through the nozzle of the spinneret, and the cellulose is regenerated into solid filaments through chemical reactions. In the traditional one-time acid bath molding process, the spinning speed is severely limited due to the speed of the filament reaction. Increasing the spinning speed will lead to a decrease in filament strength and even filament breakage.

[0003] A secondary molding process can be used to improve the strength of the filaments and increase the spinning speed. At this time, in order to reduce the concentration of the acid bath in the second molding, the residual acid on the filaments and the drum needs to be scraped off; since the scraper needs to be in direct contact with the drum and the filaments for a long time, the degree of wear is high and needs to be replaced and maintained frequently; if a scraper is directly installed and fixed on the machine, each replacement requires disassembly of the fixed connection structure, and maintenance is time-consuming and labor-intensive, affecting production efficiency.

[0023] Example 1

[0024] The present embodiment is a scraper for spinning equipment, which is specifically suitable for the secondary molding process of continuous spinning of regenerated cellulose fibers. It is arranged between the first molding step and the second molding step, and is used to scrape off the acid liquid remaining on the drum after the first molding. It mainly includes a connecting structure and a scraper 4, and the connecting structure is used to connect the scraper 4 and the mounting position on the machine, such as a fixing rod for installing a wire dividing rod.

[0025] like Figure 1 As shown, the connecting structure includes a connecting plate 2, and a card slot 1 is provided at one end of the connecting plate 2; the card slot 1 is an elastic cylindrical structure with an opening on one side along the length direction, which is tangent to the connecting plate 2 and is integrally arranged; a mounting groove 3 is integrally arranged at the other end of the connecting plate 2, and the mounting groove 3 is a cylindrical structure with an opening on one side along the length direction, and its opening and central axis are both coplanar with the connecting plate 2; a disassembly hole 21 is provided on the connecting plate 2, and since the card slot 1 is fixed tightly when installed in the installation position of the machine, the disassembly hole 21 is opened, and the scraper and the connecting structure can be removed by using a crowbar and the disassembly hole 21, so that it is more convenient and labor-saving to disassemble and replace the scraper.

[0026] A mounting column is provided on one side of the scraper 4 that cooperates with the mounting groove 3. The outer diameter of the mounting column is the same as the inner diameter of the mounting groove 3. The thickness of the scraper 4 is the same as the opening width of the mounting groove 3, so that the scraper 4 can be inserted into the mounting groove 3 from the side for installation.

[0027] like Figure 2 As shown, the scraper 4 is a parallelogram structure, which can provide a diversion effect for the acid scraped from the drum when in use, prompting the acid to flow in the same direction, so as to collect the acid and avoid the acid dripping on the silk strips to cause uneven molding and other problems.

[0028] When this embodiment is actually used, the connecting structure is first installed to the installation position on the spinning machine through the card slot 1, so that it is set at the position between the first molding area and the second molding area, and then the scraper 4 is pushed into the installation slot 3 from the side of the installation slot 3; after the installation of the scraper 4 is completed, the connecting structure is rotated so that the guide edge 5 of the scraper 4 contacts the surface of the drum; when the spinning equipment is running, the drum rotates, and the acid liquid remaining thereon will be scraped off by the guide edge 5 of the scraper 4, and drip uniformly through the lowest point of the guide edge 5 and enter the collecting device for collection.

[0029] Example 2

[0030] The difference between this embodiment and embodiment 1 is that Figure 3 and Figure 4As shown, both side edges of the scraper 4 in this embodiment are perpendicular to the mounting column, and one side of the scraper 4 away from the mounting groove 3 is set as a chamfered edge 5, which is inclined relative to the length direction of the mounting column.

[0031] When the scraper 4 is installed and used, the chamfered edge 5 will have a height difference in the vertical direction; the chamfered edge 5 is also the side that directly contacts the drum to scrape off the acid. After the acid is scraped off from the chamfered edge 5, it will automatically slide along the chamfered edge 5 toward the lowest point due to the height difference of the chamfered edge 5.

[0032] Example 3

[0033] The difference between this embodiment and embodiment 2 is that Figure 5 As shown, the scraper 4 in this embodiment is an arc-shaped scraper 6; the side projection of the arc-shaped scraper 6 is an arc, and the side in contact with the drum is convex and the other side is concave.

[0034] The above is only a further explanation of the present invention in combination with specific embodiments. All descriptions do not limit the protection scope of the present invention. Any changes or replacement schemes that can be easily thought of by technicians in this field within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
