Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of food machinery, and more specifically to an anti-overflow knife shaft component of a chopping machine. Background Art
[0002] Traditional small and medium-sized chopping machines have two structures: cantilever type and two-end support type. Most of them have a knife shaft extending horizontally into the chopping pot, and the chopping knife is installed on the knife shaft. When working, the knife shaft drives the chopping knife to rotate at high speed, and the chopping pot rotates slowly around the vertical axis, while the chopping pot cover is stationary. There is a certain gap between the knife shaft and the edge of the chopping pot and the chopping pot cover. The knife shaft in this structure is exposed to the outside, and its disadvantages are: 1. Due to the high-speed rotation of the knife shaft and the chopping knife, some fillings and juices in the pot will overflow outward along the knife shaft, which not only wastes food but also leaves overflows on the side and increases the difficulty of cleaning; 2. The knife shaft has no protection, and the cleaning water directly contacts the knife shaft, which greatly reduces the safety of product operation. Utility Model Content

[0005] Furthermore, the sheath unit also includes a sealing ring, and a sealing ring is provided on the end surface of the knife shaft sheath located inside the chopping pot cover.
[0006] Furthermore, the sealing ring is a lip-shaped sealing ring, and its lip faces the inside of the chopping pot cover.
[0007] Furthermore, the outer diameter of the knife shaft sleeve extending into the chopping pot cover is larger than the outer diameter of the knife shaft sleeve outside the chopping pot cover.
[0008] Furthermore, the connecting section between the blade shaft sleeve and the waterproof bearing seat is a stepped outer circle, and the diameter is larger than the outer circle diameter located outside the chopping pot cover; the waterproof bearing seat is sleeved on the blade shaft sleeve and pressed tightly on the stop of the stepped outer circle.
[0009] Furthermore, the bearing unit also includes an adjustment pad and an end cover; the end cover is fixedly connected to the waterproof bearing seat, and the adjustment pad is located in the end cover and pressed against the end face of the self-aligning ball bearing.
[0010] Furthermore, the chopping knife unit includes multiple chopping knives, left-handed nuts, right-handed nuts, multiple knife seats, and multiple connecting screws; each knife seat is provided with a chopping knife, the knife seat is sleeved on the outer circle of the knife shaft, the left-handed nut and the right-handed nut are screwed together with the left and right ends of the knife shaft, and the multiple knife seats are pressed and fixed in the middle of the knife shaft, and the multiple connecting screws are locked after passing through the knife seats.
