The itemize machine knife is apart from positioner
Technical field
The utility model belongs to the packing mechanical equipment field, relates to a kind of banding machine, relates in particular to a kind of itemize machine knife apart from positioner.
Background technology
Banding machine is with cutter the coiled material of certain width vertically to be cut out to cut open, and is cut into the used device of several narrower bundlings.Cutting device on the tradition banding machine generally is to adopt upper cutter shaft and lower cutter shaft to match to cut, wherein go up cutter shaft and be provided with carving knife, lower cutter shaft is provided with the notch that cooperates with carving knife, the dimensions that will cut out minute according to coiled material, distance between the carving knife on the upper cutter shaft is adjusted to required specification, cut again.Usually the dimensions that will cut out minute of coiled material has multiple, whenever change and once cut out minute size, the distance between the carving knife just need to be readjusted once, and is generally with ruler that the dimensional measurement on the upper cutter shaft is good first, locate after again carving knife being moved to this position, comparatively waste time and energy; And because hand dipping error easily occurs by cutter the time, cause the size of last cutting inaccurate, so that strip becomes defective work.
Therefore, how addressing the above problem, is the content that the utility model will be studied.
Summary of the invention
The utility model provides a kind of itemize machine knife apart from positioner, and its purpose mainly is to solve present cutter to waste time and energy and the problem of error easily occurs apart from adjustment.
For achieving the above object, the technical solution adopted in the utility model is: a kind of itemize machine knife comprises cutter shaft, carving knife apart from positioner; Also comprise positioning sleeve, this positioning sleeve is sheathed on the cutter shaft, and between two adjacent carving knives.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the different size specification that the size of described positioning sleeve can will be cut out minute according to coiled material, customize in advance, need to change and cut out when dividing size, only the positioning sleeve of correspondingly-sized need to be sheathed on the upper cutter shaft, then the distance between two carving knives just has been fixed, and does not need to measure with scale in addition again; Time saving and energy saving, convenient by cutter, and size is difficult for makeing mistakes.
Because technique scheme is used, the utility model compared with prior art has following advantages:
Because the utility model adopts positioning sleeve fixing by cutter, the different size specification that the positioning sleeve size will be cut out minute according to coiled material customizes in advance.Need to change and cut out when dividing size, only the positioning sleeve of correspondingly-sized need to be sheathed on the upper cutter shaft, then the distance between two carving knives just has been fixed, and does not need to measure with scale in addition again; Time saving and energy saving, and convenient by cutter, size is difficult for makeing mistakes.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
In the above accompanying drawing: 1, upper cutter shaft; 2, carving knife; 3, positioning sleeve.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: as shown in Figure 1, a kind of itemize machine knife comprises cutter shaft 1, carving knife 2 apart from positioner; Also comprise positioning sleeve 3, this positioning sleeve 3 is sheathed on the cutter shaft 1, and between two adjacent carving knives 2.
Adopt positioning sleeve 3 fixing by cuttves, the different size specification that positioning sleeve 3 sizes will be cut out minute according to coiled material customizes in advance.Because the tool rest of carving knife 2 has certain thickness,, need this thickness is taken into account during positioning sleeve 3 in customization, reserve the margin of tolerance, to guarantee that by behind the cutter, the size between two carving knives 2 is just for cutting out a minute size.When change cutting out minute size, only the positioning sleeve 3 of correspondingly-sized need to be sheathed on the upper cutter shaft 1, again carving knife 2 be got on to get final product by cutter, then the distance between two carving knives just has been fixed at this moment, does not need to measure with scale in addition again; Time saving and energy saving, and convenient by cutter, size is difficult for makeing mistakes.
Above-described embodiment only is explanation technical conceive of the present utility model and characteristics, and its purpose is to allow the personage who is familiar with technique can understand content of the present utility model and according to this enforcement, can not limit protection domain of the present utility model with this.All equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed within the protection domain of the present utility model.
