[0002] Youpi, also known as oil bean curd skin, tofu skin, bean curd skin or tofu skin, is a common soy product and is widely loved by consumers. The production method of Youpi is simple. After obtaining soy milk using the traditional method, the temperature of the soy milk is maintained between 70℃ and 90℃ for a period of time, and the surface of the soy milk will form a crust and wrinkles. You only need to peel off the bean curd skin and spread it out to dry, and you can get the oil skin after it is dried.

[0003] The production and processing of oil leather has long been done manually. The thickness of traditional handmade oil leather is uneven, and it is seriously damaged. The qualified rate of finished products is generally around 65%. In addition, due to manual operation, the labor intensity is high, the production efficiency is low, and the quality of the finished products, especially the sanitary standards, is difficult to guarantee. In order to change the current situation of the industry, a large number of automatic stretching oil leather equipment have appeared on the market, which can basically realize the industrialized production of oil leather.

[0004] However, the current mechanized oil leather production equipment has the following problems:

[0005] 1. The air outlet pipe of the existing oil leather production equipment will form condensed water droplets on the surface of the air outlet pipe due to the temperature difference.

[0069] Basic principles of the present invention:

[0070] The heated soybean milk enters the discharging trough 12 through the discharging box 11, and enters the forming trough 21 through the screen 13. The air pump 15 drives the telescopic rod 1 341 of the air drying device 3 to extend, and the air drying device 3 moves toward the direction of the transport device 4.

At this time, the air drying device 2 6 moves towards the air drying device 3.

[0071] When the air-drying device 3 is in contact with the air-drying device 2 6, the connecting seat 312 of the air-drying device 3 is in an ascending state, and the lead screw 2 65 of the air-drying device 2 6 is in a descending state, so the air outlet pipe 32 of the air-drying device 3 is above the air outlet pipe 2 66 of the air-drying device 2 6, and the cleaning member 2 67 of the air-drying device 2 6 can clean the water droplets condensed on the lower surface of the air outlet pipe 32 of the air-drying device 3;

[0072] As the air drying device 3 moves toward the transport device 4, the push rod 348 located below the connecting member 34 will scrape off the soy milk residue on the bottom surface of the molding groove 21, and the cutting blade 35 will cut the oil skin adhered to the side wall of the molding groove 21 to prevent the oil skin from adhering to the inner wall of the molding groove 21;

[0073] When the air-drying device 3 moves to the side close to the transporting device 4, the push rod 348 pushes the soybean milk residue into the residue discharge groove 26; the pushing block 314 of the air-drying device 3 is squeezed by the side wall and moves inward, and through the cooperation of the rack 315 and the gear 313, the connecting seat 312 is driven to move downward, and the extrusion block 344 drives the telescopic rod 2 346 to extend, and drives the push rod 348 to move upward, and the oil skin on the inner edge of the forming groove 21 is picked up (the oil skin is driven to move upward for a distance to separate the oil skin from the soybean milk);

[0074] At this time, the air drying device 2 6 is transported to the side close to the discharging device 1, and the push block 2 64 of the air drying device 2 6 is squeezed, and the lead screw 2 65 moves upward through internal cooperation, driving the air outlet pipe 2 66 to move upward;

[0075] The gripper 41 of the transport device 4 grabs the oil skin, and transfers the formed oil skin to the feeding device 5 through the transport roller 42, and the oil skin is transported and collected through the feeding roller 51 and the feeding conveyor belt 53;

[0076] During the gripping process of the transport device 4, the formed oil skin will slide over the top of the push rod 348 to prevent the oil skin from sticking to the soy milk and causing soy milk splashing during transportation;

[0077] After the oil skin is transported, the air pump 15 stops providing air pressure to the telescopic rod 1 341 and the telescopic rod 3 61; the elastic rod 342 and the elastic rod 2 62 drive the air drying device 3 and the air drying device 2 6 to move in the opposite direction to air dry the newly formed oil skin inside the forming groove 21. At this time, the air outlet pipe 32 of the air drying device 3 is below the air outlet pipe 2 66 of the air drying device 2 6. When the two are in contact, the cleaning member 33 of the air drying device 3 cleans the water droplets on the lower surface of the air outlet pipe 2 66 of the air drying device 2 6.

[0078] When the air-drying device 3 moves to the side close to the discharging device 1, the pushing block 314 on the other side of the extrusion control member 31 drives the connecting seat 312 upward, drives the extrusion block 344 to move upward, thereby contracting the telescopic rod 346, and drives the push rod 348 to move downward. The push rod 348 will descend along the edge of the molding groove 21 close to the discharging device 1, cut the oil skin formed on the edge of the molding groove 21, and prevent the oil skin from adhering to the edge of the molding groove 21;

[0079] Then the air-drying device 3 moves towards the transporting device 4 under the action of the air pump 15, and performs secondary air-drying, picking and transporting of the newly formed oil leather;

[0080] Repeating the above steps can achieve high-efficiency production of the oil skin, while reducing the problem of condensed water droplets dripping due to temperature difference in the air outlet pipe 32, causing pits and holes on the surface of the oil skin, affecting the aesthetics of the oil skin and the problem of the oil skin sticking to the side wall.
