Description

Technical Field

[0001] The present invention relates to the technical field of pomelo processing, and particularly to a pomelo surface scratching device for food processing. Background Art

[0002] As a common fruit, pomelo has a wide range of applications in the fields of food processing and medicinal extraction. In some processing technologies, it is necessary to scratch the surface of the pomelo. Traditional pomelo processing methods mostly rely on manual operation or simple mechanical equipment. Although these methods can complete the scratching process, there are many problems, seriously affecting the processing efficiency and product quality.

[0003] There are generally problems such as unstable processing accuracy, cumbersome operation, and low automation in pomelo scratching devices. Existing devices mostly use fixed blades or rolling blades for scratching. However, due to the individual differences in the thickness, hardness, and shape of the pomelo peel, it is difficult to ensure uniform depth with the traditional blade scratching method. Scratching too deep may damage the pulp, and scratching too shallow will affect subsequent processing. In addition, the shape of the pomelo is relatively smooth, and the existing clamping mechanisms are difficult to fix firmly, and are prone to sliding or offset during the scratching process, resulting in broken and irregular scratching lines, affecting the overall processing effect.

[0004] In addition, existing devices often neglect the cleaning and water removal links, and pomelo is prone to adhering impurities or residual moisture before and after processing. If not cleaned before scratching, the tool may be contaminated by impurities, reducing its service life and affecting the scratching quality. If the water on the pomelo after scratching is not removed in time, it may affect the drying of the peel or cause mildew during storage and subsequent processing. Summary of the Invention

And the output end of the fourth hydraulic rod 16 drives the fourth connecting plate 18 to move, so that the fourth connecting plate 18 drives the second connecting block 19 to move and drives the connecting frame 401 to move. Then, by starting the compression cylinder 1101, the compressed gas is transported into the inside of the air pipe 1102, and the gas ejected from the air knife 1103 blows off the residual water on the surface of the pomelo, thereby driving the pomelo to move to the position of the support pipe 21, so that the second limiting rod 20 contacts the pomelo. Then, the output end of the first hydraulic rod 202 drives the first connecting plate 203 to slide inside the support frame 201 and drives the first fixing rod 205 to move, so that the first fixing rod 205 drives the fixing needle 206 to insert into the inside of the pomelo and fix the pomelo. The output end of the second hydraulic rod 301 drives the connecting frame 302 to move, so that the connecting frame 302 slides on the outer wall of the first fixing rod 205 and drives the second connecting plate 303 and the connecting rod 305 to move, so that the scratching plate 308 and the scratching knife 309 contact the pomelo. Pressure is applied through the movement of the second connecting plate 303, and the scratching plate 308 is pulled by the third tension spring 3010 to rotate on the connecting rod 305, so that the scratching knife 309 inserts into the pomelo and moves on the pomelo. Then, the second connecting plate 303 moves upward to drive the connecting rod 305, and the scratching plate 308 is pulled by the second tension spring 307 to move, so that the other end of the scratching knife 309 inserts into the pomelo, achieving scratching on the surface layer of the pomelo. Through the third tension spring 3010 and the second tension spring 307, the scratching knife 309 can insert into the epidermis when the hardness and radian of the pomelo epidermis change, and the cutting angle and pressure of the scratching knife 309 are automatically adjusted through the third tension spring 3010 and the second tension spring 307 to avoid being too deep or too shallow, and the scratching lines on the pomelo epidermis are ensured to be continuous and uniform through scratching twice. The connecting rod 305 rotates on the second fixing rod 306, and then the connecting rod 305 is pulled by the first tension spring 304 so that the outer wall of the scratching plate 308 fits on the outer wall of the pomelo.After the scratch is completed, the output end of the first motor 408 drives the rotating rod 406 and the first gear 407 to rotate, and drives the rack 403 to drive the first limiting rod 402 to move, thereby driving the clamping rod 404 and the clamping plate 405 to move, so as to clamp the pomelo. The output end of the third hydraulic rod 13 drives the sliding frame 14 to move, so that the sliding frame 14 is on the upper surface of the limiting frame 12, drives the connecting frame 401 to move, and further moves the pomelo to the position of the storage box 9, and stores the pomelo through the storage box 9.
