Description
Technical field
The utility model relates to the adjustable feed mechanism of a kind of easy gear, relates in particular to a kind of adjustable feed mechanism of gear of cardboard cutting machine.
Technical background
Mostly existing all kinds of gear governor motion is to adopt complicated gear drive, the electrodeless transmission of belt or carry out effective transposing of gear, its complex structural designs, manufacturing cost height by the signal of telecommunication etc.
Summary of the invention
The utility model will solve the existing baroque problem of gear governor motion, and a kind of simple in structure, easy to operate adjustable feed mechanism of gear is provided.
The technical solution of the utility model:
The feed mechanism that gear is adjustable is characterized in that: comprise transfer the files axle, ladder axle sleeve, knob; Described knob sleeve puts at multidiameter, and described knob inwall is provided with many rectangular recess parallel with axis direction, and described ladder axle sleeve outer wall relevant position is provided with the protruding key of rectangle, and described knob cooperates with described multidiameter cover gap; Described multidiameter cover top is provided with the ladder platform of multiple tracks differing heights, and the described axle of transferring the files passes the ladder axle sleeve, and the described shaft head of transferring the files is provided with the umbrella shape boss that is used for the screens of ladder platform.
Further, described transferring the files placed a support spring between an outer wall and the ladder sleeve lining, and described spring heads on the shaft head of transferring the files.
Further, a described bottom of transferring the files has a level trough and a vertical channel of placing steady pin.
Further, described umbrella shape boss external diameter is less than the internal diameter of knob and greater than the internal diameter of ladder axle sleeve.
A top of transferring the files when during original state or the external world does not have load contacts with knob all the time.
Operation principle of the present utility model: regulate when selecting gear, the rotation knob, knob drives the ladder axle sleeve and rotates, and the ladder platform that multidiameter puts rotates the relevant position; During extraneous the loading, the structure of rotating around dead axle rotates, and the pin on it drives the axially motion down of transferring the files, and the umbrella shape boss of the axle of transferring the files puts corresponding ladder contact with platform with multidiameter, has stoped the axle of transferring the files to continue to glide, thereby has realized the gear adjusting.
The utility model is applied to the cardboard cutting machine, turns over angle in order to the knife rest maximum of controlling the cardboard cutting machine, promptly controls the following cutter amount of each cardboard cutting.
The beneficial effects of the utility model: simple in structure, simple to operate, safety.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 be transfer the files the axle part drawing.
Fig. 3 is the part drawing of axle sleeve of transferring the files.
Fig. 4 is the part drawing of knob of transferring the files.
Fig. 5 is the profile along the A-A line of Fig. 4.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further.
With reference to Fig. 1-5, the feed mechanism that gear is adjustable comprises transfer the files axle 1, ladder axle sleeve 2, knob 3; Described knob 3 is enclosed within on the ladder axle sleeve 2, and described knob 3 inwalls are provided with many rectangular recess parallel with axis direction 10, and described ladder axle sleeve 2 outer wall relevant positions are provided with the protruding key 8 of rectangle, described knob 3 and described ladder axle sleeve 2 matched in clearance; Described ladder axle sleeve 2 tops are provided with the ladder platform 9 of multiple tracks differing heights, and the described axle 1 of transferring the files passes ladder axle sleeve 2, and described axle 1 head of transferring the files is provided with the umbrella shape boss 5 that is used for 9 screens of ladder platform.
Described transferring the files placed a support spring 4 between axle 1 outer wall and ladder axle sleeve 2 inwalls, described spring 4 heads on axle 1 head of transferring the files.
Described axle 1 bottom of transferring the files has a level trough 6 and a vertical channel 7 of placing steady pin.
Described umbrella shape boss 5 external diameters are less than the internal diameter of knob 3 and greater than the internal diameter of ladder axle sleeve 2.
Concrete operation method of the present utility model is as follows: regulates when selecting gear, and rotation knob 3, knob 3 drives ladder axle sleeve 2 and rotates, and the ladder platform 9 on the ladder axle sleeve 2 rotates the relevant position; During extraneous the loading, the structure of rotating around dead axle rotates, and the pin on it drives the axle 1 of transferring the files and moves downward, and corresponding ladder platform 9 contacts on the umbrella shape boss 5 of the axle 1 of transferring the files and the ladder axle sleeve 2 have stoped the axle 1 continuation downslide of transferring the files, thereby realized the gear adjusting.After plus load was cancelled, regulating spring 4 utilized screen resilience that gear shift axle 1 is pushed up back and contacts with the interior top of chamber of knob 3.
The utility model is applied to the cardboard cutting machine, turns over angle in order to the knife rest maximum of controlling the cardboard cutting machine, promptly controls the following cutter amount of each cardboard cutting.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
