Compared with the prior art, knife sharpening device has the advantages of simple and reasonable overall structure and low cost, is practical and reliable, and is easy to manufacture and convenient and quick to operate, the belt can be replaced quickly and easily through the cam adjusting part, and the device can be operated by a signal person independently and saves time and labor.
Description
Technical field
The utility model relates to a kind of knife sharpening device, belongs to the sharpening mechanical equipment technical field, refers in particular to a kind of knife sharpening device that improves structure.
Background technology
In the prior art, a class knife sharpening device is arranged, it adopts belt gear that cutter is ground, and with respect to manual operations, has improved operating efficiency, has reduced the cost expenditure.But, existing this knife sharpening device, when needing to change belt, because belt is in tensioned state when being wound on the runner, and do not have the degree of tightness governor motion, thus be difficult to belt is unloaded or loads onto, and single very difficult this loading and unloading of independently finishing, therefore, be necessary prior art is improved accordingly.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of simple in structure, easy to operate, the knife sharpening device that can change the improvement structure of belt fast easily is provided.
To achieve these goals, the utility model is realized by following technical scheme:
A kind of knife sharpening device that improves structure, include support and be located at belt gear on the support, described belt gear comprises power motor, driving wheel, first driven pulley and second driven pulley and is wound in belt on driving wheel, first driven pulley and second driven pulley; Further, described belt gear also includes and is used to regulate the belt tightness so that load and unload the cam adjustment parts of belt, and the cam adjustment parts are connected interlock with first driven pulley.
Further, described cam adjustment parts include :-bearing, and it is fixedly set on the support;-connecting shaft, fixedly connected with first driven pulley in the one end, and slide and be arranged on the bearing in the other end;-back-moving spring, it is set on the connecting shaft and provides the power that resets for it;-turning handle, one end be provided with one with the eccentric cam of working day and night and being dynamically connected.
Further, described cam adjustment parts also include a trimming assembly, and trimming assembly includes :-to win in succession, it is fixedlyed connected with connecting shaft;-swing handle, it is distolateral that its activity is assemblied in bearing, and the lower end contacts cooperation with the contact of winning in succession;-goring push spring, its both ends are fixed in the distolateral plate contact of deciding of bearing with the bottom and of winning in succession respectively and contact cooperation.
The utility model compared with prior art, its beneficial effect is:
1, overall structure advantages of simple is made easily, and cost is low, and is practical reliable;
2, convenient to operation, can be easy to change belt fast by the cam adjustment parts, and can single independent operation, time saving and energy saving.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of trimming assembly.
The specific embodiment
As shown in Figure 1, 2, the knife sharpening device of improvement structure described in the utility model, include support 1 and the belt gear of being located on the support 2, described belt gear 2 comprises power motor 21, driving wheel 22, first driven pulley 23 and second driven pulley 24 and is wound in belt 25 on driving wheel 22, first driven pulley 23 and second driven pulley 24, wherein driving wheel 22 is in transmission connection with power motor 21, the power output of power motor 21 is driven to first driven pulley 22 and second driven pulley 24, and then drive belt 25 cycle rotations.
Further, described belt gear 2 also includes and is used to regulate belt 25 tightness so that load and unload the cam adjustment parts 3 of belt 25, and described cam adjustment parts 3 include :-bearing 31, and it is fixedly set on the support 1;-connecting shaft 32, fixedly connected and interlock with first driven pulley 23 in the one end, and slide and be arranged on the bearing 31 in the other end;-back-moving spring 33, it is set on the connecting shaft 32 and provides the power that resets for it;-turning handle 34, one end are provided with an eccentric cam 341 that is rotationally connected with connecting shaft 32.
Further, described cam adjustment parts 3 also include a trimming assembly 4, and trimming assembly 4 includes :-win 41 in succession, it is fixedlyed connected with connecting shaft 32;-swing handle 42, it is distolateral that its activity is assemblied in bearing 31, and the lower end contacts cooperation with 41 contacts of winning in succession;-goring push spring 43, its both ends are fixed in distolateral plate 44 contacts of deciding of bearing 31 with 41 bottoms and of winning in succession respectively and contact cooperation.
When belt 25 was in running order, turning handle 34 was in substantially with connecting shaft 32 and be arranged in parallel, and this moment, connecting shaft 32 was protruding and fix this position under the elastic force effect of back-moving spring 33, and belt 25 is tauted; And when needs are changed belt 25, only need to rotate turning handle 34 about 90 degree, the eccentric cam 341 of turning handle 34 contacts with bearing 31 end wall contacts and promotes connecting shaft 31 compression reseting springs 33 and inwardly slides at this moment, first driven pulley 23 inwardly slides thereupon, and because the slip effect of first driven pulley 23, belt 25 is progressively released, can be easy to unload or load onto; On the other hand,, can regulate the angle of inclination of first driven pulley 23, thereby further fine setting makes belt 25 be in best duty by turn swing handle 42.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
