Specific implementation mode
The invention will be further described with the following Examples.
Opening bottom of paper bag device provided in this embodiment is shown in Fig. 1, Fig. 2, including pedestal 1, driving gear set is equipped in pedestal 1
2, the power of output gear 31 is transmitted in tube pulling 8 (as shifting part) by driving gear set 2, so that tube pulling 8 is rotated, so as to beat
Open the bottom of paper bag.
Together referring to Fig. 3, Fig. 4, Fig. 5, input shaft 4 is equipped with rolling bearing 41 and axle sleeve 42, and output gear 31 is sleeved on rolling
On dynamic bearing 41 and axle sleeve 42, output gear 31 is made to be rotatably sleeved on input shaft 4.Second gear 32 (as output wheel)
It is fixedly set on the stretching cylinder 311 of output gear 31.(as the connector) upper end of swing rod 62 is fixed in by connecting rod 61
In the center of rotation of first gear 63 (as driving wheel).The lower end inside face of connecting rod 5 and the side of 4 right end of input shaft are equipped with
Keyway (see Figure 10), the lower end of connecting rod 5 are affixed by driving key (not shown) and keyway with the right end of input shaft 4.Connecting rod 5 it is upper
End is hinged in connecting rod 61 so that first gear 63 and second gear 32 keep engagement, and make the centre-to-centre spacing of two gears
It remains unchanged (see Fig. 5).Guiding cylinder 71 is fixed on turbine 74 (as fixing piece) (see Fig. 9), guides 71 phase of cylinder
Pedestal 1 is fixed, swing rod 62 is equipped with guiding groove 621 (as guide rail) and enters for guiding cylinder 71, guides in cylinder 71
Mandrel line and the pivot center of second gear 32 are mutually parallel.
It is transmitted from input shaft 4 to 31 power of output gear as follows：
The power of motor (not shown) is input to input shaft 4, and input shaft 4 drives connecting rod 5 to rotate, and connecting rod 5 drives connection
Bar 61 rotates, to drive first gear 63 around the center axis thereof of input shaft 4, to drive second gear 32 to rotate.By
It is fixed on swing rod 62 in first gear 63, swing rod 62 is driven movement.Since guiding 71 opposite base 1 of cylinder is fixed, pendulum
Bar 62 (guiding cylinder 71 is located in guiding groove 621) during movement, swing rod 62 is rotated relative to guiding cylinder 71, and
And moved relative to guiding cylinder 71, to drive first gear 63, around its own pivot axis, (rotation makes the second tooth
The velocity of rotation of wheel 32 changes).Output gear 31 and second gear 32 are affixed, and power is exported from output gear 31.
Specific motion principle is as follows：
See Fig. 4, since the upper end of swing rod 62 is fixed in by connecting rod 61 in first gear 63, swing rod 62 and first gear
63 rotate together, therefore can be simplified to component as shown in FIG. 6.Fig. 7, Fig. 8 are seen, when first gear 63 turns to position from position A
B, then from during position B moves to position C, first gear 63 is remained to engage and (be nibbled with 32 (not shown) of second gear
Chalaza track is curve H in Fig. 7).See that Fig. 7, connecting rod 5 drive first gear 63 around the center axis thereof of input shaft 4 (along direction
D), to drive second gear 32 to rotate, this is relative motion a.In the process, opposite 71 turns of the cylinder of guiding of swing rod 62
It is dynamic, and moved relative to guiding cylinder 71 so that around its own pivot axis (along direction E), this is first gear 63
Relative motion b1.Relative motion a is synthesized with relative motion b1, makes first gear 63 from during position A turns to position B,
The mean speed of second gear 32 is higher than the rotating speed of input shaft 4.See that Fig. 8, first gear 63 turn to the mistake of position C from position B
Cheng Zhong similarly understands first gear 63 around its own pivot axis (along direction G, direction G is opposite with direction E), this is phase
To moving b2.Relative motion a is synthesized with relative motion b2, makes first gear 63 from during position B turns to position C, and
The mean speed of two gears 32 is less than the rotating speed of input shaft 4.In conclusion the speed of second gear 32 during the work time is in week
Phase property changes, and speed is transmitted in tube pulling 8 by second gear 32 by output gear 31 and driving gear set 2, to make to dial
Pipe 8 is worked with periodically variable speed.
Regulating mechanism has scroll bar 73 to be rotatably arranged at as shown in figure 9, the adjusting pedestal 72 including being fixed on pedestal 1
In the turbine seat 721 for adjusting pedestal 72.There is turbine 74 to be rotatably arranged to adjust in pedestal 72, guiding cylinder 71 is fixedly set
On turbine 74.Rotation scroll bar 73 makes turbine 74 rotate, and the angle position of guiding cylinder 71 can be adjusted, to adjust swing rod
62 angle position makes second gear 32 rotate, to adjust the angle position of tube pulling 8.
Mode of speed regulation is as follows：
Fixed block 741 is fixed on turbine 74, and screw rod 742 is rotatably connected on fixed block 741, rotates 742 energy of screw rod
Guiding cylinder 71 is enough set to be moved along regulating tank 743, to change 32 turns of central axis and the second gear of guiding cylinder 71
The distance between shaft line, to make the amplitude of 32 velocity variations of second gear change, to change when opening paper bag bottom,
The instantaneous velocity of tube pulling 8.According to the difference of paper bag bottom width, the size of the distance is adjusted, opening bottom of paper bag device can be made suitable
The production of a variety of paper bags different for bottom width.
Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected
The limitation of range is protected, although being explained in detail to the present invention with reference to preferred embodiment, those skilled in the art answer
Work as understanding, technical scheme of the present invention can be modified or replaced equivalently, without departing from the reality of technical solution of the present invention
Matter and range.
