[0020] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.
[0021] like Figure 1As shown, as a high temperature resistant feed machine ring die of the utility model, it includes a ring die body 1, and the ring die body 1 is set as a ring die made of silicon nitride ceramics. The high temperature resistance is increased by the ring die body 1 made of silicon nitride ceramics, thereby improving the service life of the product. A plurality of rows of die holes 2 are opened on the ring die body 1, and connecting flanges 3 are arranged at both ends of the ring die body 1. A positioning plate 4 is arranged between the two connecting flanges 3, such as Figure 3 As shown, the facing surfaces of the two connecting flanges 3 are provided with a slide groove 6 which is concentric with the ring die body 1, and both ends of the positioning plate 4 are fixed with a limit rod 10 which is slidably arranged with the slide groove 6. The positioning plate 4 is located at the periphery of the ring die body 1, and a pressure spring 8 is arranged at the position of the inner side of the positioning plate 4 corresponding to the die hole 2, and a cleaning block 9 is arranged at the end of the pressure spring 8. The cleaning block 9 is inserted into the die hole 2 by the extension of the pressure spring 8 to clean the die hole 2, and the cleaning block 9 is pulled out of the die hole 2 by the contraction of the pressure spring 8 to clean the die holes 2 in other columns. At the same time, as the positioning plate 4 rotates, the cleaning block 9 is driven to clean the die holes 2 in different columns. The corresponding positions can easily and quickly find the position of the die hole 2, thereby improving the cleaning efficiency.
[0022] like Figure 4 As shown, the cleaning block 9 is set to be a hollow truncated cone, and the end of the cleaning block 9 with a larger area is connected to the pressure spring 8, and the area of the end of the cleaning block 9 with a larger area is larger than the cross-sectional area of the die hole 2, and the area of the end of the cleaning block 9 with a smaller area is smaller than the cross-sectional area of the die hole 2, and the cleaning block 9 passes through the die hole 2. The inclined side wall of the hollow truncated cone-shaped cleaning block 9 can realize that the cleaning block 9 can be automatically pulled out of the die hole 2 as the positioning plate 4 rotates, which is beneficial to improve the overall cleaning efficiency. By passing the cleaning block 9 through the die hole 2, it is ensured that the cleaning block 9 has sufficient length to push out the contents of the die hole 2, thereby ensuring the stable progress of the cleaning work.
[0023] like Figure 4 As shown, a plurality of jet holes 7 are provided on the cleaning block 9, and when the cleaning block 9 is inserted into the die hole 2, the jet holes 7 are just completely located in the die hole 2, and a jet pipe penetrating the pressure spring 8 and connected to the external air pump is provided at the hollow part of the cleaning block 9, and a plurality of jet holes 7 are connected to the jet pipe, and the side wall of the die hole 2 is sprayed through the jet holes 7, thereby avoiding the problem of unclean cleaning caused by the smaller area of one end of the cleaning block 9, thereby improving the cleaning effect.
[0024] like Figure 2As shown, a placement groove 5 for accommodating the cleaning block 9 is provided on the outer surface of the ring die body 1 at a position corresponding to the cleaning block 9. The placement groove 5 is located between two rows of die holes 2 and there is a gap between the die holes 2. The width of the positioning plate 4 is not greater than the spacing between the die holes 2 on both sides of the placement groove 5. The cleaning block 9 is accommodated by the placement groove 5, thereby limiting the positioning plate 4 to avoid blocking the die holes 2 due to the rotation of the positioning plate 4 when the ring die body 1 is working. At the same time, the width of the positioning plate 4 is not greater than the spacing between the die holes 2 on both sides of the placement groove 5 to ensure that the positioning plate 4 will not block the normal discharge of the die holes 2 when the cleaning block 9 is located in the placement groove 5.
[0025] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
