Technical Field

[0001] This utility model relates to the technical field of walnut oil cold pressing equipment, specifically an energy-saving hydraulic cold pressing device for walnut oil. Background Technology

[0002] Walnut oil is a vegetable oil made by pressing walnut kernels. The energy-saving walnut oil hydraulic cold pressing device uses low-temperature cold pressing technology. The walnut kernels are pressed at a temperature below 60°C through a hydraulic system, which avoids the damage of high temperature to the nutrients and natural color of the oil. The cold pressing process has low energy consumption and does not require additional heating treatment, making it more energy-efficient and in line with the concept of green and healthy diet.

This method is time-consuming and labor-intensive, resulting in low efficiency of walnut oil cold pressing. Therefore, an energy-saving hydraulic cold pressing device for walnut oil is proposed to address the above problems. Utility Model Content

[0025] Work process: This device can be used in conjunction with a feeding device. Before use, the power is turned on, and the lower end of the oil collection tray 25 is connected to the walnut oil collection device. The device is equipped with an external controller, which is electrically connected to the hydraulic cylinder 22, the first telescopic rod 27, the drive motor 32, the second telescopic rod 36, and the multi-stage electric push rod 42. The operating status of the hydraulic cylinder 22, the first telescopic rod 27, the drive motor 32, the second telescopic rod 36, and the multi-stage electric push rod 42 can be adjusted by manually operating the external controller. All of the above are existing technologies.When using the device, the operator first feeds an appropriate amount of walnut kernels into the cold-pressing box 44 located at the rear using the feeding device. Then, the external controller retracts the two first telescopic rods 27, causing the two first locking blocks 28 to move downwards, thus releasing the locking of the first locking blocks 28 onto the two limiting blocks 45 located at the front. Subsequently, the external controller automatically retracts the multi-stage electric push rod 42 located at the front. The multi-stage electric push rod 42, fixed by the second mounting plate 41, can drive the transmission block 43 and the cold-pressing box 44 located at the front to move forward a specific distance. Then, the external controller automatically extends the two second telescopic rods 36 located at the front, causing the two second... When locking block 37 moves upward, it locks the two limiting blocks 45 located on the front side. Simultaneously, the external controller automatically retracts the two second telescopic rods 36 located on the rear side, causing the two second locking blocks 37 located on the rear side to move downward, thus releasing the locking of the two limiting blocks 45 on the rear side. The external controller also automatically extends the multi-stage electric push rod 42 located on the rear side, which drives the transmission block 43 and the cold pressing box 44 located on the rear side to move forward a specific distance. The two limiting blocks 45 move from inside the second track 35 to inside the first track 26. Then… The external controller automatically extends the two first telescopic rods 27, causing the two first locking blocks 28 to move upwards. This locks the two rear limit blocks 45. Then, the operator can extend the two hydraulic cylinders 22 via the external controller. These cylinders, fixed to the mounting bracket 21, move the pressure plate 23 downwards, placing it inside the rear cold-pressing chamber 44. Oil is pressed using the pressure plate 23, and the extracted walnut oil is collected and discharged through the oil collection tray 25. Simultaneously, the external controller automatically rotates the front drive motor 32, which is fixed to the motor by the motor base 12. A fixed drive motor 32 drives the first mounting plate 31 located at the front to rotate. The two sets of rotating wheels 34 fixed by the rotating wheel seat 13 can make the limiting ring 33 rotate stably. The limiting ring 33 can support the first mounting plate 31. The second track 35 and the second locking block 37 can lock the two limiting blocks 45 located at the front, so that the cold pressing box 44 can rotate synchronously with the first mounting plate 31. The cold pressing box 44 can rotate one revolution. If there is walnut meal in the cold pressing box 44, the walnut meal can fall into the receiving box 14 on the upper side of the bottom plate 11. The operator can repeat the above operation to quickly load, press and unload the two cold pressing boxes 44 respectively.This device allows for the alternating use of two movable cold-pressing boxes 44. One cold-pressing box 44 is positioned above the worktable 24, locked by a first locking block 28 to the limiting block 45, and pressed by a vertically movable pressing plate 23. Simultaneously, the other cold-pressing box 44 is positioned above the first mounting plate 31, locked by a second locking block 37 to the limiting block 45, and tilted by a rotatable second track 35, automatically discharging the walnut pulp. This device features automatic feeding, simple operation, time and labor saving, and continuous pressing through two cold-pressing boxes 44, resulting in high cold-pressing efficiency.
