[0020] The motor 38 is started, and the motor 38 drives the worm 37 to rotate, the worm 37 drives the worm wheel 36 to rotate, and the worm wheel 36 drives the bevel gear three 34 to rotate. Since the bevel gear three 34 is engaged with the bevel gear one 32 and the bevel gear two 33 at the same time, the bevel gear one 32 and the bevel gear two 33 can be made to rotate coaxially and in opposite directions, and then the inner shaft 21 and the outer sleeve 23 can also be made to rotate coaxially and in opposite directions. Therefore, the stirring blade one 221 and the stirring blade two 231 rotate in opposite directions to stir the material, thereby improving the stirring efficiency and improving the emulsification effect.

[0021] Reference Figure 4 , Figure 5 as well as Figure 6The scraper 4 includes an exhibition board 41, a connecting rod 42 and an insert 43. The exhibition board 41 is a sheet-like thin plate.

The hinge block 402 of one of the two adjacent display boards 41 is inserted into the hinge groove 413 of the other display board 41, and the hinge block 402 is hinged in the hinge groove 413. One end of the connecting rod 42 is hinged to the outer wall on the side of the upper notch 411 in the display board 41, and the other end passes over the adjacent display board 41 and is hinged to the outer wall on the side of the lower notch 412 in the subsequent display board 41. Connecting rods 42 are provided on both sides of each display board 41. The insert block 43 is used to be inserted into the upper notch 411 between the two top display boards 41, and when the insert block 43 is inserted between the two display boards 41, the insert block 43 is interference-fitted in the upper notch 411 between the two display boards 41. In addition, the bottom display board 41 in the scraper 4 is fixedly connected to the stirring member 2, one end of the pull wire 5 is fixed to the top display board 41, and the other end is wound in the wire take-up assembly 6.

The take-up wheel 61 is located at one side of the bottom end of the inner shaft 21, and the outer wall of the take-up wheel 61 has a plurality of jacks 611 along its circumference; the mounting plate 62 is fixed to the inner shaft 21, and a short sleeve 621 is fixed to the mounting plate 62, and the take-up wheel 61 is rotatably arranged on the short sleeve 621, and one end of the short sleeve 621 extends out of the take-up wheel 61; the locking rod 63 is in a U shape, and one end of the locking rod 63 is used for interference fit with the inner hole of the short sleeve 621, and the other end is interference fit with the jack 611. When the two ends of the locking rod 63 are inserted between the short sleeve 621 and the take-up wheel 61, the take-up wheel 61 can be locked. A pull rod 612 is vertically fixed on the outer wall of the take-up wheel 61. The pull rod 612 is located at the edge of the take-up wheel 61. The operator can rotate the take-up wheel 61 by holding the pull rod, which makes it easier for the operator to use the take-up assembly 6.

[0023] When it is necessary to scrape the inner wall of the emulsifying cylinder 1, pull out the locking rod 63, unlock the take-up assembly 6 to release the wire, and then pull the top display board 41 close to the inner wall of the emulsifying cylinder 1 until the tapered strip 401 on the display board 41 conflicts with the inner wall of the emulsifying cylinder 1, and then insert the insert block 43 into the upper notch 411 between the two display boards 41 at the top, thereby, each display board 41 will be in a state of conflicting with the inner wall of the emulsifying cylinder 1, and then start the driving unit 3 to rotate the stirring element 2, thereby driving the wall scraper 4 to rotate, so that the inner wall of the emulsifying cylinder 1 can be scraped.

[0024] This application can explain its functional principle through the following operation methods: When making salad dressing and emulsifying the raw materials containing dietary fiber, the plug block 43 at the top of the scraper 4 is taken out, and then the wire drawing assembly 6 is used to tighten the pull wire 5. As the pull wire 5 is tightened, the top display board 41 will move to the side away from the emulsifying cylinder 1, and under the action of the connecting rod 42 in the scraper 4, each display board 41 will be rolled up, so that the scraper 4 will be rolled up. When the scraper 4 is rolled up to the final roll, the wire drawing assembly 6 is locked, and the pull wire 5 is in a taut state. Then, the driving unit 3 is started, and the stirring element 2 is driven to rotate under the action of the driving unit 3. At this time, the pull wire 5 also rotates. The pull wire 5 can cut the dietary fiber, which can improve the emulsification effect of the salad dressing containing dietary fiber. In addition, during the emulsification process, the emulsified material will pass through the gap between two adjacent display boards 41, which can further improve the effect of shearing the dietary fiber.

[0025] When the emulsification is completed and the inner wall of the emulsification cylinder 1 needs to be scraped and rinsed, the pull wire 5 is released, and then the top display board 41 is pulled close to the inner wall of the emulsification cylinder 1, and then the plug block 43 is inserted into the upper notch 411 between the two display boards 41 at the top. Each display board 41 will be in a state of conflict with the inner wall of the emulsification cylinder 1, and then the driving unit 3 is started to rotate the scraper 4, so that the inner wall of the emulsification cylinder 1 can be scraped.
