In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
The conventional replacement mode of the slicing knife 200 is to lift the slicing knife 200 to the top position of the knife holder 500 and then detach the slicing knife 200 from the knife holder 100 for replacement, because the slicing knife 200 is long and heavy, the worn slicing knife 200 is detached and a new slicing knife 200 is lifted and installed in the knife holder 100, the slicing knife 200 is easy to fall off, and there is a great safety risk.
As shown in fig. 1, in one embodiment, a method for replacing a slicing knife 200 is provided, which can replace the slicing knife 200 in a slicing machine, and the replacement process can ensure safety and avoid safety accidents.
Specifically, the method for replacing the slicing knife 200 comprises the following steps:

In one embodiment, when the slicing knife 200 needs to be replaced, the knife holder 100 is moved vertically upward by a predetermined distance relative to the cutting plane 400 by a moving mechanism (not shown), so that the cutting edge 210 of the slicing knife 200 is flush with the cutting plane 400, i.e., the cutting edge 210 of the slicing knife 200 is flush with the cutting plane 400, which facilitates the removal of the slicing knife 200 from the knife holder 100 in a direction parallel to the cutting plane 400.
In another embodiment, when the slicing knife 200 needs to be replaced, the knife holder 100 is driven by the moving mechanism to vertically move upward for a preset distance relative to the cutting plane 400, so that the cutting edge 210 of the slicing knife 200 is spaced from the cutting plane 400 to form a replacement gap, and the replacement gap is matched with the wear length of the slicing knife 200, so that the slicing knife 200 can be smoothly taken down after being detached from the knife holder 100 without interference or interference.
The preset distance can be flexibly adjusted or designed according to actual use requirements, and can be within 2cm, for example.
Further, step S200 includes step S210, after the slicing knife 200 is flush with the cutting plane 400 or a replacement gap is formed at an interval, supporting the knife holder 100 to keep the knife holder 100 and the slicing knife 200 still.
Specifically, the knife holder 100 drives the slicing knife 200 to move upward by a preset distance, so that the knife holder 100 is supported by the support element after the cutting edge 210 of the slicing knife 200 is flush with the cutting plane 400 or a replacement gap is formed at an interval, and the knife holder 100 and the slicing knife 200 can be stably kept in a static state relative to the cutting plane 400, thereby avoiding falling in the replacement process.

S300, the slicing knife 200 is detached from the knife holder 100 for replacement. Thus, after the slicing knife 200 is flush with the cutting plane 400 or a replacement gap is formed between the slicing knife 200 and the cutting plane 400, the slicing knife 200 is removed from the knife holder 100 and a new slicing knife 200 is remounted on the knife holder 100, thereby realizing replacement of the slicing knife 200.
In addition, before the step S200, a step S100 of detecting a wear degree of the slicing knife 200 is further included, and if the wear degree of the slicing knife 200 exceeds a preset degree, the knife seat 100 is moved up by a preset distance, so that the slicing knife 200 is flush with the cutting plane 400 or a replacement gap is formed at an interval. Therefore, the wear condition of the slicing knife 200 can be accurately monitored by using the wear degree detection element, so that the slicing knife 200 can be accurately and timely replaced, the influence on the uniformity of slice thickness due to untimely replacement is avoided, the material loss due to too early replacement is also avoided, and the use cost is reduced.
In the actual production process, when the wear detecting element detects that the wear of the slicing knife 200 does not exceed the preset level, the slicing knife 200 can continue to cut the sliced sheet.
It should be noted that the preset degree can be flexibly designed or adjusted according to actual production needs, and it is only necessary to satisfy the requirement that the thickness of the sliced sheet cut by the slicing knife 200 is kept uniform when the wear degree does not exceed the preset degree.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," "circumferential," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are not to be considered limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.
In the present invention, unless otherwise explicitly stated or limited, the terms "mounted," "connected," "fixed," and the like are to be construed broadly, e.g., as being permanently connected, detachably connected, or integral; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meanings of the above terms in the present invention can be understood according to specific situations by those of ordinary skill in the art.
In the present invention, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature may be directly under or obliquely under the first feature, or may simply mean that the first feature is at a lesser elevation than the second feature.
It will be understood that when an element is referred to as being "secured to," "disposed on," "secured to," or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Further, when one element is considered as "fixed transmission connection" with another element, the two elements may be fixed in a detachable connection manner or in an undetachable connection manner, and power transmission can be achieved, such as sleeving, clamping, integrally-formed fixing, welding and the like, which can be achieved in the prior art, and is not cumbersome. When an element is perpendicular or nearly perpendicular to another element, it is desirable that the two elements are perpendicular, but some vertical error may exist due to manufacturing and assembly effects. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
It should also be understood that in explaining the connection relationship or the positional relationship of the elements, although not explicitly described, the connection relationship and the positional relationship are interpreted to include an error range which should be within an acceptable deviation range of a specific value determined by those skilled in the art. For example, "about," "approximately," or "substantially" may mean within one or more standard deviations, without limitation.
The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The above examples only show some embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent should be subject to the appended claims.
