The feed roller includes wheel hub 1 and cylindrical shell 2, passes through several between the shell and wheel hub
Rib 3 offers several through-holes 201 on the shell；Each through-hole 201 extends along the circumferencial direction of shell respectively.It is each logical
Hole is connected to the inner cavity 100 of feed roller.By attached drawing it is found that wheel hub 1 and shell 2 are to be coaxially disposed.Feed roller described herein
Inner cavity refers to the cavity between 2 inner wall of 1 outer wall of wheel hub and shell.Referring to Fig. 8, in actual use, the two of feed roller inner cavity 100
End is connected to vacuum tank 91, so that each through-hole 201 is connected to vacuum tank 91, therefore each through-hole is gone at the top of feed roller
Suction-operated is played after being contacted with corrugated board 900, to improve adsorption capacity so that the transmission of corrugated board 900 is more stablized.
Further, it is equiangularly disposed along 1 circumferencial direction of propeller boss to please refer to each rib 3 described in Fig. 3, Fig. 4 and Fig. 5,
The length of each rib 3 is equal to the length of propeller boss 1；1 length of propeller boss is less than the length of shell 2.By attached drawing it is found that in hub axis
On 81 directions, wheel hub is located at the middle part of shell, i.e. feed roller is symmetrical arranged along the symmetry axis 82 perpendicular to hub axis.The setting
Not only the bonding strength between wheel hub and shell had been improved, but also so that the length of wheel hub is shortened, is i.e. the inner cavity of feed roller
Increase, when being more convenient for working normally, the inner cavity that outer gas stream can be smoothly through shell after through-hole enters back into vacuum
In case, resistance when air-flow passes through housing cavity is reduced, to ensure that feed roller steadily adsorbs corrugated board.
Further, 1 outer wall of wheel hub, which corresponds to, is respectively set that there are one reinforced sheets 4 between a two neighboring rib of meaning 3, respectively
A reinforced sheet is connected to the inner wall of shell.By the way that reinforced sheet is arranged, the bonding strength between hub shell is further improved.It is attached
6 ribs and 6 reinforced sheets are schematically depicted in figure, but not limited thereto.
For the ease of processing, the wheel hub 1, shell 2, each rib 3 and each reinforced sheet 4 are integrally formed.
The specific of through-hole detailed below opens up mode.Fig. 2 and Fig. 3 are please referred to, in order to improve through-hole on shell
Expanded range, each through-hole are 30 ° ~ 210 ° along shell circumferencial direction extension angle.
Preferably, each through-hole is 180 ° along shell circumferencial direction extension angle.
Further, in the plane perpendicular to hub axis 81（That is the visual angle of vertical view）, the projection energy of all through-holes
Enough form the circle of a completion.That is, in 360 degree of rotation processes of each feed roller, case top has through-hole to face watt always
The bottom of corrugated paper board 900 further improves the stability of paper feeding.
Preferably, as shown in figure 3, for the ease of processing, 4 through-holes are offered altogether on the shell；The 2 of shell the same end
Projection of a through-hole in the plane perpendicular to hub axis forms a complete circle.
Further, projection of 2 through-holes of shell the same end in the plane perpendicular to hub axis is completely superposed；Shell
Projection of 2 through-holes in the plane perpendicular to hub axis in the middle part of body is completely superposed.In other words, 2 of shell the same end
Through-hole 201 is symmetrical arranged along the symmetry axis 82 perpendicular to hub axis；2 through-holes 201 of housing central section are along perpendicular to hub spindle
The symmetry axis 82 of line is symmetrical arranged.The processing of through-hole had both been convenient in the setting, while also ensureing feed roller rotation process, and feed roller is whole
The rotary balance of body so that more stablize when feed roller rotates.
Fig. 6 and Fig. 7 are please referred to, the utility model correspondingly provides a kind of vacuum adsorption conveying device, the vacuum suction
Conveying device includes exhaust fan（It is not shown in figure）, vacuum tank 91 is arranged at the top of vacuum tank and offers the lattice of several gate hole
Screen 92, the more shafts 93 horizontally across vacuum tank, and the driving device for driving every shaft to rotate（In figure not
It shows）.Unlike the prior art, in vacuum adsorption conveying device provided by the utility model, in every shaft 93 respectively
Multiple feed rollers as previously described are arranged, feed roller is identical as the quantity of the gate hole and is arranged correspondingly, each to send
The top of paper wheel from stretching out on flase floor in that corresponding gate hole upwards.Above-mentioned exhaust fan and driving device be the prior art and
It is not the utility model point place of the utility model, therefore attached drawing does not draw exhaust fan and goes out driving device.Only shown with dotted line in Fig. 7
Meaning property represents vacuum tank 91.Specifically setting can be the driving device：The driving device includes motor, on electric machine main shaft
It is provided with synchronous pulley, that one end that motor is corresponded in each shaft is respectively arranged with synchronous pulley, and passes through synchronous belt and electricity
Belt wheel on owner's axis links together, to realize that motor drives each shaft rotation.
Referring to Fig. 8, operation principle described briefly below：In actual use, exhaust fan is connected to by pipeline with vacuum tank, exhausting
Vacuum tank is pumped into negative pressure state after machine operation.Shaft is passed through from the through-hole 101 of feed roller wheel hub, and feed roller is sleeved on by realization
In shaft.
After driving device drives each shaft 93 to rotate synchronously, each feed roller correspondingly rotates.At this point, in addition to feed roller
Air draught effect is generated at gap 9201 between shell 2 and gate hole, stretches out the through-hole 201 on the part shell of gate hole upwards
Play air draught use, and part through-hole 201 and corrugated board distance closer to（The direct corrugated board of through-hole of case top part
Bottom stick together）, therefore improve the adsorption capacity to corrugated board 900.Simultaneously as feed roller rotates, corrugated board
It is steadily linearly sent out, therefore improves the stability of paper feeding, correspondingly improved printing quality.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to the protection of the utility model
Range.
