Description
Technical field
The utility model is related to a kind of cleaning devices of carry-over pinch rolls, belong to technical field of spinning equipment.
Background technology
The carry-over pinch rolls of draft gear in spinning machine, fly frame or similar machine by positioned at upside upper roller and be located at downside
Lower roll constitute.Since sliver is drawn between upper roller and lower roll, the raw material of sliver be cotton in the case of cotton sugar,
The other materials of finish or such as flying hair in the case where the raw material of sliver is chemical fibre can be attached to the appearance of carry-over pinch rolls
On face, it is therefore desirable to a cleaning device is equipped with for carry-over pinch rolls, for regularly removing this attachment and cleaning carry-over pinch rolls.
As traditional cleaning device, there are following two structures：A kind of structure, wherein be made of flexible element (fin)
Belt contacted with carry-over pinch rolls, so as to by flying hair or the like bat fall (see patent document 1)；And another structure, wherein
Rubber block is contacted with the outer surface of carry-over pinch rolls, and flying hair or the like is wiped off (see patent document 2).
Patent document 1：Japanese Patent Publication 6-10376 bulletins
Patent document 2：Japanese Utility Model registers No. 2605843 bulletins
However, can be forcefully attached on the outer surface of carry-over pinch rolls since cotton sugar, finish or the like have viscosity,
Therefore, in the cleaning device using belt or rubber block, belt or rubber block can only be with faint scraping force and traction roller surface
It contacts and tangentially scrapes carry-over pinch rolls, cannot certainly remove above-mentioned attachment to clean carry-over pinch rolls.Using rubber block
In above-mentioned cleaning device, since rubber block is periodically removed from carry-over pinch rolls so that attachment is fallen, have the following problems：
The attachment on carry-over pinch rolls cannot be removed when rubber block moves away.
Application No. is 200510083546.9 Chinese invention patents to disclose a kind of cleaning device of carry-over pinch rolls, it includes
One wiper, along the axially extending of the carry-over pinch rolls and tool, there are one the sharp ends contacted with the outer surface of the carry-over pinch rolls
Edge, and the sharp ora terminalis of the wiper in a manner of with the centerline axis parallel of the carry-over pinch rolls with the carry-over pinch rolls
Outer surface contacts；The wiper is extruded on the outer surface of the carry-over pinch rolls by one pressurizing unit, the pressurizing unit, so that
It is generated between them and squeezes contact.The sharp ora terminalis of wiper and the centerline axis parallel of carry-over pinch rolls, therefore work as the traction
When roller rotates, the cotton sugar, the finish or the like that are attached on the outer surface of the carry-over pinch rolls can be certainly by the sharp ora terminalis
It wipes off；Cotton sugar, finish or the like can forcefully be wiped off under the effect of the pressure of the extrusion, even if the wiper
The sharp ora terminalis can more or less be worn over time, but the extrusion can still remain the carry-over pinch rolls
Specified extruding force；Therefore, clean unevenness can be minimized, and solve above-mentioned technical problem well.But it should
The cleaning device of carry-over pinch rolls has the following disadvantages：
1, above-mentioned cleaning device is equipped with a holder for keeping the wiper, and the holder is to can oneself
It is located at by the mode installed or removed on the bearing block of the carry-over pinch rolls, but the dismounting of its holder and wiper installation replaces ten
Divide inconvenience；
2, the sharp ora terminalis of wiper and the centerline axis parallel of carry-over pinch rolls, since fiber is concentrated mainly in process of production
It in the middle part of carry-over pinch rolls, therefore is easy to strut wiper so that the fiber on both sides is not easy to be eliminated；
3, the extrusion that pressurizing unit is constituted using leaf spring or the like, there are fatigue limits, are using a period of time
After need replacing, increase production cost.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of sanitizer cartridge of carry-over pinch rolls for the above-mentioned prior art
It sets, it can equably dispose the attachment being adhered on carry-over pinch rolls outer surface such as loose wool or finish, to cleanable
Carry-over pinch rolls.
The technical scheme in the invention for solving the above technical problem is：A kind of cleaning device of carry-over pinch rolls, feature
It is：It includes a wiper, and along the axially extending of the carry-over pinch rolls and tool, there are one the outer surfaces with the carry-over pinch rolls
The sharp arc-shaped ora terminalis of contact, the sharp arc-shaped ora terminalis of the wiper is in the arc-shaped with the outer surface of the carry-over pinch rolls
Mode is contacted with the outer surface of carry-over pinch rolls, and the high two side portions in middle section of sharp arc-shaped ora terminalis are low.
Further include attracting part, part attracted to attract wiper on the outer surface of the carry-over pinch rolls, make wiper and carry-over pinch rolls it
Between generate attract contact.
Part is attracted to use magnet.
Further include fixing piece, fixing piece is located at the bearing block for being positioned to fixing piece, the setting of fixing piece edge
There is rib to limit wiper.
Fixing piece edge rib carries out freely positioning, wiper both sides and fixing piece edge guard contact free to wiper, scrapes
Part freely can be removed or be loaded onto from carry-over pinch rolls.
Wiper is made of synthetic resin, and hardness is less than carry-over pinch rolls appearance surface hardness.
Sharp arc-shaped ora terminalis has upper and lower twice, and sharply arc-shaped ora terminalis is arranged symmetrically upper and lower twice, wherein lower road is sharp
Arc-shaped ora terminalis middle section is provided with opening.
Wiper includes fixed seat, and scraper plate is provided in fixed seat, and sharp arc-shaped ora terminalis is set to scraper plate front.
Compared with prior art, the utility model has the advantage of：
1, a kind of cleaning device of carry-over pinch rolls of the utility model, simple in structure, dismounting installation is replaced very convenient；
2, a kind of cleaning device of carry-over pinch rolls of the utility model, wiper use arc-shaped sharp ora terminalis, are divided into front and back
On the one hand twice can make fiber disperse to both sides, prevent fiber from being concentrated in the middle part of roller so that fiber more easy-clear；It is another
The scraper structure of twice can effectively ensure that final cleaning effect before and after aspect；
3, a kind of cleaning device of carry-over pinch rolls of the utility model, uses the form of magnet that wiper is adsorbed in carry-over pinch rolls
On, there is no fatigue limits to be conducive to the maintenance in later stage without being replaced, reduce production cost.
