Description
Technical field
The utility model relates to cigarette processing mechanical apparatus technical field, in particular to a kind of cigarette unit aspirator band is dust-proof
Guide wheel.
Background technique
Pipe tobacco is formed relatively thin pure tobacco layer by feeding system, is thrown into vertical aspirator road, vertical aspirator road is by one
The suction function that high-pressure ventilation fan provides is in air chamber, the mesh aspirator band of one continuous operation of device, air compartment on air chamber
Body provides enough negative pressure to vertical aspirator road by the mesh on aspirator band, the pipe tobacco being thrown into aspirator road is obtained enough
Speed rises with air-flow.It is adsorbed in the tobacco bunch blank formed on mesh aspirator band, and is forced to convey.And it will be more by stabilization device
Remaining pipe tobacco, which is trimmed, returns to wire feeding system.The pipe tobacco for meeting technological standards after trimmer mechanisms are trimmed is transported to roll paper
On, tobacco bunch is driven by cigarette paper after negative pressure disappears above enters opium pipe channel, forms plume.In the operation of aspirator band, by
In being the very big environment of an ash fines dust quantity in air compartment, higher want is proposed for the leakproofness of deep groove ball bearing therein
It asks.Although what existing bearing was selected is band by rubber sealing structure, but still is not able to satisfy the requirement of too small dust seal,
Through operation after a period of time, has a large amount of fine dusts and enter in the rolling element of bearing, cause the damage of bearing.So several
It requires to check these aspirators band introduction daily, it is smooth to look at whether bearing rotates, is increased to the maintenance of equipment
Burden also brings hidden danger to the formation of stablizing of tobacco bunch.The utility model improves axis by changing aspirator band Guiding wheel structure shape
The leakproofness held reduces the pollution of bearing dust, improves the service life of equipment, reduces production cost.
Summary of the invention
The purpose of the utility model is to provide a kind of cigarette unit aspirator band dustproof guide pulleys.
Purpose of the utility model is realized as follows: a kind of cigarette unit aspirator band dustproof guide pulley, including aspirator belt wheel
Body, axis, bearing, end cap, fluorine glue outside framework oil seal, shaft end ring, aspirator band wheel body center prolong axial direction and offer bearing
Installation through-hole, the bearing are installed in the bearing installation through-hole, it is characterised in that: aspirator band wheel body side opens up
There is the end cap mounting groove around the bearing installation through-hole, prolongs in the end cap mounting groove and be axially provided with several fixation holes；
Fluorine glue outside framework oil seal is installed in the bearing side, and end cap is installed in the bearing other side；The end cap shape and the end cap are pacified
Tankage is consistent, several through-holes corresponding with the fixation hole position, the end cap and aspirator are provided on the end cap
Band wheel body passes through the through-hole by screw, fixation hole is fixed；The axis passes through bearing and fluorine glue outside framework oil seal, the fluorine
The transversal cross-section of glue outside framework oil seal and shaft connection place is S type；Being provided between the bearing and fluorine glue outside framework oil seal prevents bearing
The shaft end ring of axial movement offers the groove for fixing the shaft end ring in the bearing installation through-hole.
The beneficial effects of the utility model are: the dust-proof effect of guide wheel is obvious, bearing after using the sealing guide wheel of new construction
Service life significantly extended, about improve 10-20 times or more, reduce the abrasion of axis, mitigate the pressure of point inspection, reduce and tie up
The time is repaired, the cost of equipment is reduced, improves the operational efficiency of equipment.

Rights protection scope is subject to claims.
Specific embodiment
Referring to Fig. 1 ~ 3, a kind of cigarette unit aspirator band dustproof guide pulley, including aspirator band wheel body 1, axis 2, bearing 3, end cap 4,
Fluorine glue outside framework oil seal 5, shaft end ring 6, the aspirator band 1 center of wheel body prolong axial direction and offer bearing installation through-hole 11, institute
It states bearing 3 to be installed in the bearing installation through-hole 11, it is characterised in that: aspirator band wheel body side is offered around described
The end cap mounting groove 12 of bearing installation through-hole prolongs in the end cap mounting groove 12 and axial is provided with several fixation holes 13；It is described
3 side of bearing is equipped with fluorine glue outside framework oil seal 5, and end cap 4 is installed in 3 other side of bearing；The end cap shape and the end cap
Mounting groove is consistent, several through-holes corresponding with the fixation hole position are provided on the end cap；The end cap and suction
Silk ribbon wheel body passes through the through-hole by screw 7, fixation hole is fixed；The axis passes through the bearing 3 and fluorine glue skeleton oil
The transversal cross-section of envelope 5, the fluorine glue outside framework oil seal 5 and 2 junction of axis is S type；Between the bearing 3 and fluorine glue outside framework oil seal 5
