Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] The utility model provides Figure 1-3 The refractory fiber spinning machine shown in the figure includes a spinning machine body 1, a feed port 2 and a material door 3, the material door 3 is hinged at one end of the feed port 2, the feed port 2 is fixedly arranged on one side of the spinning machine body 1, and a support structure 4 is provided on the back of the feed port 2, the support structure 4 includes a support rod 401, a through slot 402 and a guide assembly, the through slot 402 is opened at one end of the feed port 2, the support rod 401 is T-shaped and inserted into the inner cavity of the through slot 402, and is used for limiting the position of the material door 3 when it is opened, and the guide assembly is arranged between the support rod 401 and the feed port 2. When the material door 3 is in the open state, 401 can penetrate the through slot 402 opened on the feed port 2 and squeeze the inner wall of the material door 3, so that the material door 3 remains in the open state under the squeezing of the support rod 401, avoiding the manual support of the material door 3, providing convenience for feeding into the feed port 2, and the support rod 401 is set in a T-shape, which is convenient for the operator to apply force to the support rod 401 away from the end of the through slot 402, thereby increasing the force range of the support rod 401, providing convenience for the use of the support rod 401, and thus providing support effectiveness for the material door 3.

[0021] Furthermore, the guide assembly includes a guide rod 403 and a guide groove 404. The guide groove 404 is opened on the back of the feed port 2. The guide rod 403 is slidably inserted into the inner cavity of the guide groove 404. The end of the guide rod 403 away from the guide groove 404 is fixed to the support rod 401. The guide groove 404 is inclined and opened on the back of the feed port 2. The inclination amplitude is consistent with the inclination of the top of the pressure block 506, which is consistent with the movement trajectory of the support rod 401. The guide rod 403 is fixed to the support rod 401 and the guide groove 404. 4 slides and interpenetrates, so that the support rod 401 can drive the guide rod 403 to move along the inner cavity of the guide groove 404 while moving, thereby ensuring the stability of the movement of the support rod 401. At the same time, the guide rod 403 can also ensure the stability of the position of the support rod 401 on the back of the feed port 2. Cooperating with the interpenetration of the positioning rod 501 and the positioning groove 502, the support rod 401 is prevented from easily falling from the back of the feed port 2, thereby improving the stability of the position of the support rod 401 and also improving the effectiveness of the position movement of the support rod 401.

[0022] Furthermore, a positioning structure 5 for limiting the position of the support rod 401 is provided between the support rod 401 and the feed port 2. The positioning structure 5 includes a positioning rod 501, a positioning groove 502 and a mounting block 503. The mounting block 503 is fixedly provided on the back of the feed port 2. The positioning rod 501 is slidably inserted into the inner cavity of the mounting block 503. The top end of the positioning rod 501 is slidably inserted into the inner cavity of the positioning groove 502. The positioning groove 502 is provided at the bottom end of the support rod 401. The cross-sectional shape of the positioning groove 502 is as follows: Figure 3 As shown in , the bottom end of the support rod 401 is opened, and one side of the inner cavity of the positioning groove 502 is connected to the top end of the support rod 401. The initial top end of the positioning rod 501 is interlaced with the inner cavity of the positioning groove 502. As the support rod 401 moves, the range of the interlacing between the positioning rod 501 and the inner cavity of the positioning groove 502 gradually increases until the top end of the positioning rod 501 extends out of the inner cavity of the positioning groove 502 and extends to the top end of the support rod 401. The support rod 401 cannot continue to move toward the material door 3. At the same time, in the absence of external force, the interlaced connection between the positioning rod 501 and the positioning groove 502 will maintain the stability of the position, thereby stably supporting the opening state of the material door 3. The outer wall of the positioning rod 501 is fixed with a support spring 504, and the inner cavity of the mounting block 503 is provided with an I-shaped groove. The support spring 504 is movably arranged in the inner cavity of the I-shaped groove. The cam 504 is used to stabilize the position of the positioning rod 501 in the inner cavity of the mounting block 503. The positioning rod 501 is movable and inserted in the inner cavity of the mounting block 503 by means of the support spring 504. When the positioning groove 502 moves toward the material door 3 as the support rod 401 moves, the top end of the positioning rod 501 will be inserted with downward pressure, so that the positioning rod 501 moves downward by means of the compression performance of the support spring 504. When one side of the positioning groove 502 moves to the top end of the positioning rod 501, the positioning rod 501 will pop up upward by means of the automatic elastic force of the support spring 504, so that it can pass through the inner cavity of the positioning groove 502 and extend to the top of the support rod 401. The setting of the I-shaped groove in the inner cavity of the mounting block 503 facilitates the position restriction of the two ends of the support spring 504, thereby ensuring the effectiveness of the use of the support spring 504 and enhancing the flexibility of the use of the positioning rod 501.

[0023] Finally, the positioning structure 5 also includes an extrusion rod 505 and a pressure block 506. The extrusion rod 505 is fixedly arranged on the back of the feed port 2 and above the support rod 401. The pressure block 506 is fixedly arranged on the top of the support rod 401. The top of the pressure block 506 is inclined, the extrusion rod 505 is in an inverted L shape, and the bottom end of the extrusion rod 505 is in an arc shape, which is used to squeeze the pressure block 506 to change the moving height of the support rod 401. As the support rod 401 moves toward the material gate 3, the extrusion rod 505 will squeeze the pressure block 506. By utilizing the inclination of the top end of the pressure block 506 and the arc surface of the bottom end of the extrusion rod 505, the pressure block 506 under pressure will move downward during the movement, thereby being able to The support rod 401 is able to move synchronously, so that the insertion connection between the positioning rod 501 and the positioning groove 502 requires an inclined force to be able to insert and connect. Therefore, after the support rod 401 supports the material door 3, the reverse thrust generated by the material door 3 to the support rod 401 cannot generate a driving force on the support rod 401. When the support rod 401 moves in the reverse direction, it is necessary to press the positioning rod 501 and then the support rod 401 moves in the reverse direction while moving upward, so as to release the support limit for the material door 3. Under the setting of the extrusion rod 505 and the pressure block 506, the effectiveness of the support rod 401 in supporting the material door 3 is guaranteed, and the support rod 401 is prevented from being moved by the horizontal extrusion of the material door 3, thereby improving the stability of the support rod 401.

[0024] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
