Description

Technical Field

[0001] The utility model relates to the technical field of rotating nozzles, in particular to a novel rotating nozzle. Background Art

[0002] The rotating nozzle in the cake spreading machine is a key component, which is involved in the uniform spreading of cream and the leveling of the cake surface. In the cake making process, the traditional method is to manually use a spatula to spread the cream on a rotatable turntable, but this method is inefficient and relies on the skills of the workers. In order to improve efficiency and ensure the quality of the cake, modern cake spreading machines use a mechanized automatic spreading system.

[0003] The rotating nozzle plays a key role in the cake spreading machine. It is usually installed on the machine and connected to the cream delivery system. When the cake is placed on the rotating turntable, the rotating nozzle will start working and spread the cream evenly on the sides and upper end of the cake. The design of the rotating nozzle can ensure the uniformity and leveling effect of the cream spreading, thereby improving the appearance quality of the cake.

[0004] In order to ensure the normal operation of the cake spreading machine and the quality of cake making, the sealing of the rotating nozzle is very important. Poor sealing may cause the inside of the rotating nozzle to be eroded by materials such as cream, thereby accelerating the wear and aging of parts, increasing the erosion of parts by materials, and thus shortening the service life of the machine. Therefore, we need a new type of rotating nozzle. Utility Model Content

When the working temperature rises, the center sleeve 4 and the outer sleeve 3 expand, and the center sleeve 4 overcomes the pulling force of the magnet 8 and moves toward the large end to avoid the center sleeve 4 and the outer sleeve 3 from bulging and suffocating. At the same time, the conical surfaces fit accurately to maintain good sealing. The magnet 8 attracts the washer 9 to make the conical surfaces of the center sleeve 4 and the outer sleeve 3 always fit together, and the conical surfaces of the center sleeve 4 and the outer sleeve 3 maintain good sealing, thereby improving the sealing effect of the rotating nozzle.

[0023] Specifically, the upper end cover 1 forms a fixed structure with the lower end cover 2 through the central plug sleeve 4, and the central plug sleeve 4 is arranged between the upper end cover 1 and the lower end cover 2.

[0024] Through the above technical solution, it is convenient to connect the upper end cover 1 with the lower end cover 2 through the central plug sleeve 4, so that the upper end cover 1 and the lower end cover 2 are connected and the connection effect is achieved.

[0025] Specifically, the central plug sleeve 4 is conical in shape.

[0026] The above technical solution facilitates the change of the central plug sleeve 4 from a cylindrical shape to a conical shape. When the working temperature rises, the central plug sleeve 4 and the outer cylindrical sleeve 3 expand, and the conical surfaces fit accurately to maintain good sealing.

[0027] Specifically, the first pipe 5 and the second pipe 6 are symmetrically arranged with the mid-perpendicular line of the central plug sleeve 4 as the symmetry axis, and the shape and size of the first pipe 5 match the shape and size of the second pipe 6 .

[0028] Through the above technical solution, it is convenient to connect the first pipeline 5 and the second pipeline 6 to penetrate the central socket 4, so that the first pipeline 5 and the second pipeline 6 are connected through the central socket 4 for transportation.

[0029] Specifically, the upper end cover 1 is adsorbed and connected to the washer 9 via the magnet 8 , and the washer 9 is arranged in the central plug sleeve 4 .

[0030] Through the above technical solution, it is convenient for the upper end cover 1 to adsorb the washer 9 through the magnet 8, and then the magnet 8 sucks the washer 9 inward, and the washer 9 adsorbs and fixes the center socket 4.

[0031] Specifically, the center plug sleeve 4 forms a snap-fit ​​structure with the lower end cover 2 through the plug 10 , and the shape and size of the inner wall of the center plug sleeve 4 match the shape and size of the outer wall of the plug 10 .

[0032] Through the above technical solution, it is convenient for the plug 10 on the top of the lower end cover 2 to block and seal the bottom of the central plug sleeve 4.

[0033] Specifically, the shape and size of the outer surface of the cover 7 match the shape and size of the inner wall of the upper end cover 1 .

[0034] Through the above technical solution, it is convenient for the sealing cover 7 to block and seal the top of the upper end cover 1, so that both the upper and lower ends of the rotating nozzle are sealed.

[0035] Working principle: When using the new rotating nozzle, first of all, the center sleeve 4 is carefully designed, and the original cylindrical shape is improved to a conical shape. This improvement not only improves its functionality, but also enhances its adaptability in high-temperature working environments. When the working temperature gradually increases, the center sleeve 4 and the outer sleeve 3 will expand due to the thermal expansion effect. At this time, the center sleeve 4 can rely on its own structural characteristics to effectively overcome the pulling force generated by the magnet 8 and move toward the large end. This movement process not only avoids the suffocation of the center sleeve 4 and the outer sleeve 3 due to excessive expansion, but also ensures that the cone surfaces can fit accurately, thereby maintaining good sealing performance. At the same time, the magnet 8 plays a vital role in the whole process. It attracts the washer 9 to ensure that the conical surface of the center sleeve 4 and the outer cylindrical sleeve 3 always maintain a tight fit. This tight fit not only further enhances the sealing of the conical surface, but also effectively prevents leakage problems that may occur in high temperature environments. Therefore, through this series of improvement measures and structural designs, the center sleeve 4 and the outer cylindrical sleeve 3 can maintain good sealing when the working temperature rises, providing a strong guarantee for the stable operation of the entire rotating nozzle, which completes all the work.
