The barrel structure plays a vital role in the performance and production efficiency of the equipment.

[0003] In the food, chemical, plastic and other industries, the processing of sticky or easily residual materials is often involved. When processed by a screw machine, due to its high viscosity and adhesion, the material is easily attached to the inner wall of the barrel. For the residual material firmly adhered to the inner wall of the barrel, conventional cleaning methods are often difficult to work. Manual cleaning is not only time-consuming and labor-intensive, but may not be able to completely remove the residue. For this reason, we urgently need to provide a barrel structure for a screw machine.

[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application discloses a barrel structure of a screw machine, referring to Figure 1-Figure 4 , including a base 1, the upper end of the base 1 is welded with a motor base 2, a drive motor 3 is installed on the side of the motor base 2, a bearing seat 4 is installed on the side of the motor base 2 away from the drive motor 3, an outer cylinder 5 is provided on one side of the bearing seat 4, the output end of the drive motor 3 passes through the bearing seat 4 and is connected to a spiral extrusion rod 6, the spiral extrusion rod 6 is arranged inside the outer cylinder 5, a circular scraper 7 is provided on the inside of the outer cylinder 5, a rubber strip 8 is fixedly connected to the outside of the circular scraper 7, the outer side of the rubber strip 8 is fitted with the inner wall of the outer cylinder 5, by arranging the circular scraper 7 on the inside of the outer cylinder 5, and the rubber strip 8 on the outside of the scraper is fitted with the inner wall of the barrel, the inner side of the circular scraper 7 is fixedly connected with two fixing pieces 9. Hidden grooves 10 are provided at both ends of the bearing seat 4. Electric cylinders 11 are installed inside the hidden grooves 10. The output end of the electric cylinder 11 passes through the side of the outer cylinder 5 and is connected to a telescopic rod 12. The two telescopic rods 12 are fixedly connected to the surfaces of the two fixed plates 9 on the side away from the electric cylinder 11. Under the drive of the electric cylinder 11, the annular scraper 7 moves horizontally on the inner wall of the outer cylinder 5. At the same time, it is ensured that during the movement of the scraper, it can fully contact the residual material on the inner wall of the barrel to ensure effective scraping of the residual material, solves the problem that the residual material inside the barrel is difficult to clean after processing sticky or residual materials, and avoids the influence of residual materials on the next processing quality.

[0021] Reference Figure 1-Figure 4 , the outer cylinder 5 is evenly fixedly connected to the inner side of the end near the bearing seat 4 with four guide rods 13, and the four corners of the circular scraper 7 are respectively slidably connected to the surface of the four guide rods 13, so that the circular scraper 7 can move in the correct direction when cleaning the inner wall of the barrel, avoiding the deviation or shaking of the scraper, thereby ensuring the effective cleaning of the inner wall of the barrel, improving the cleaning effect and the reliability of the equipment, and the outer cylinder 5 is welded with a discharge port 16 at one end away from the bearing seat 4, and the inner wall of the outer cylinder 5 near the discharge port 16 is evenly fixedly connected with four limit seats 14, and the positions of the four limit seats 14 The positions correspond to the four guide rods 13 respectively. The end of the guide rod 13 away from the bearing seat 4 passes through the limit seat 14 and is connected with a bolt 15. The limit seat 14 limits the position of the guide rod 13, thereby limiting the position of the scraper. The upper end of the base 1 is welded with a support seat 17. The upper end of the support seat 17 is sleeved on the end of the outer cylinder 5 close to the discharge port 16, which effectively enhances the stability of the barrel during operation and reduces the vibration and shaking of the barrel. Especially during high-speed rotation of the screw and material processing, it can keep the position of the barrel stable and improve the reliability and service life of the equipment.

[0022] The implementation principle of the barrel structure of a screw machine in an embodiment of the present application is as follows: during specific use, first, the driving motor 3 is started to drive the spiral extrusion rod 6 to rotate in the barrel to extrude and convey the material. When the material processing is completed, the electric cylinder 11 in the hidden groove 10 at both ends of the bearing seat 4 is started, and the output end of the electric cylinder 11 pushes the telescopic rod 12. The telescopic rod 12 drives the circular scraper 7 to move along the inner wall of the barrel under the guidance of the guide rod 13. Since the rubber strip 8 on the outside of the circular scraper 7 fits tightly with the inner wall of the barrel, the scraper can scrape off the residual material attached to the inner wall of the barrel. The limit seat 14 at one end of the outer cylinder 5 near the discharge port 16 and the bolt 15 on the guide rod 13 limit the movement of the scraper to prevent the scraper from excessive movement. During the whole process, the support seat 17 on the base 1 provides stable support for the barrel to ensure the normal operation of the equipment.
