Detailed description of the invention
The invention will be further described with the following Examples.
The opening bottom of paper bag device that the present embodiment provides, is shown in Fig. 1, Fig. 2, including pedestal 1, is provided with driving gear set in pedestal 1
2, the power of output gear 31 is delivered in tube pulling 8 (as shifting part) by driving gear set 2, makes tube pulling 8 rotate, it is thus possible to beat
Open the bottom of paper bag.
Seeing Fig. 3, Fig. 4, Fig. 5 in the lump, power shaft 4 is provided with rolling bearing 41 and axle sleeve 42, and output gear 31 is enclosed within rolling
On dynamic bearing 41 and axle sleeve 42, output gear 31 is made to be rotatably sleeved on power shaft 4.Second gear 32 (as output wheel)
It is set in stretching out on cylinder 311 of output gear 31 regularly.Fork 62 (as connector) upper end is fixed in by connecting rod 61
In the center of rotation of the first gear 63 (as drive).The lower end inside face of connecting rod 5 is all provided with the side of power shaft 4 right-hand member
Having keyway (see Figure 10), the lower end of connecting rod 5 and the right-hand member of power shaft 4 are affixed by driving key (not shown) and keyway.Connecting rod 5
Upper end thereof is in connecting rod 61 so that the first gear 63 and the second gear 32 keep engagement, and make the center of two gears
Away from keeping constant (see Fig. 5).Aimming circle cylinder 71 (as fixture) is fixed in (see Fig. 9) on turbine 74, aimming circle cylinder 71
Opposite base 1 is fixed, and fork 62 is provided with guiding groove 621 (as guide rail) and enters for aimming circle cylinder 71, aimming circle cylinder 71
The pivot center of central axis and the second gear 32 is parallel to each other.
As follows from the transmission of power shaft 4 to output gear 31 power:
The power of motor (not shown) is input to power shaft 4, and power shaft 4 drivening rod 5 rotates, and connecting rod 5 band is dynamically connected
Bar 61 rotates, thus drives the first gear 63 around the center axis thereof of power shaft 4, thus drives the second gear 32 to rotate.By
Being fixed on fork 62 in the first gear 63, fork 62 is driven motion.Owing to aimming circle cylinder 71 opposite base 1 is fixed, pendulum
Bar 62 is during motion (aimming circle cylinder 71 is positioned at guiding groove 621), and fork 62 rotates relative to aimming circle cylinder 71, and
And move relative to aimming circle cylinder 71, thus (this rotation makes the second tooth around himself pivot axis to drive the first gear 63
The velocity of rotation of wheel 32 changes).Output gear 31 is affixed with the second gear 32, and power exports from output gear 31.
Concrete motion principle is as follows:
See Fig. 4, owing to the upper end of fork 62 is fixed on the first gear 63 by connecting rod 61, fork 62 and the first gear
63 rotate in the lump, therefore can be simplified to component as shown in Figure 6.See Fig. 7, Fig. 8, when the first gear 63 turns to position from position A
B, then during position B moves to position C, the first gear 63 remains to engage with the second gear 32 (not shown) and (nibbles
Chalaza track is curve H in Fig. 7).See that Fig. 7, connecting rod 5 drive the first gear 63 around the center axis thereof of power shaft 4 (along direction
D), thus driving the second gear 32 to rotate, this is relative motion a.In the process, the relative aimming circle cylinder of fork 62 71 turns
Dynamic, and move relative to aimming circle cylinder 71 so that the first gear 63 is around himself pivot axis (along direction E), and this is
Relative motion b1.Relative motion a and relative motion b1 synthesize, make the first gear 63 during position A turns to position B,
The mean speed of the second gear 32 is higher than the rotating speed of power shaft 4.Seeing Fig. 8, the first gear 63 turns to the mistake of position C from position B
Cheng Zhong, in like manner understand the first gear 63 around himself pivot axis (contrary with direction E along direction G, direction G), this is phase
To motion b2.Relative motion a and relative motion b2 synthesize, make the first gear 63 during position B turns to position C, the
The mean speed of two gears 32 is less than the rotating speed of power shaft 4.In sum, the second gear 32 speed in the course of the work is week
Phase property changes, and speed, by output gear 31 and driving gear set 2, is delivered in tube pulling 8 by the second gear 32, so that dialling
Pipe 8 is with periodically variable speed operation.
Governor motion, as it is shown in figure 9, include the regulation pedestal 72 being fixed on pedestal 1, has scroll bar 73 to be rotatably arranged at
In the turbine seat 721 of regulation pedestal 72.Having turbine 74 to be rotatably arranged in regulation pedestal 72, aimming circle cylinder 71 sets regularly
On turbine 74.Rotating scroll bar 73 makes turbine 74 rotate, it is possible to the angle position of regulation aimming circle cylinder 71, thus regulates fork
The angle position of 62, makes the second gear 32 rotate, thus regulates 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 screw rod 742 energy
Enough make aimming circle cylinder 71 move along regulating tank 743, thus change central axis and second gear 32 turns of aimming circle cylinder 71
Distance between moving axis line, so that the amplitude of the second gear 32 velocity variations changes, thus changes when opening bottom paper bag,
The instantaneous velocity of tube pulling 8.According to the difference of paper bag bottom width, regulate the size of this distance, it is possible to make opening bottom of paper bag device fit
Production for the different multiple paper bag of bottom width.
Last it should be noted that, above example is only in order to illustrate technical scheme, rather than the present invention is protected
Protecting the restriction of scope, although having made to explain to the present invention with reference to preferred embodiment, those of ordinary skill in the art should
Work as understanding, technical scheme can be modified or equivalent, without deviating from the reality of technical solution of the present invention
Matter and scope.
