Medical device for rolling up cotton swab
This utility model relates to a kind of medical Cotton swab rolling machine.
Medical cotton stick is one of a large amount of sterilizing articles that use of each health service unit, and present employed cotton swab mostly adopts manual twisting, and not only production efficiency is low to twist cotton swab by hand, and the cotton swab specification is difficult for guaranteeing, and human body is bigger to the pollution of cotton swab.If want to overcome above-mentioned shortcoming, just must adopt mechanization production.
The purpose of this utility model is to provide a kind of medical Cotton swab rolling machine, is used for replacing the manual cotton swab that twists.
This utility model mainly comprises body, motor, and reducing gear is for the cotton machine structure, for signing mechanism and kneading mechanism.A cylinder that is driven by Geneva mechanism (or claiming Geneva wheel Geneva gear) is arranged in kneading mechanism, be uniformly distributed along the circumference on it many and sign groove, the middle part of cylinder one side is provided with a rub wheel, and opposite side is provided with out label mechanism, is covered with the cotton swab backplate along roll circumference.For the cotton machine structure be positioned at cylinder one end and with the rub wheel homonymy, comprising by partial gear, the disconnected cotton wheel that rotate a pair of intermittence of cam and control stick control, comprise in addition a pair of continuous rotation for cotton wheel.When the cotton wheel that breaks was in the moment at intermittence, the cotton wheel that supplies of continuous operation just can be taken turns intermediary cotton sliver tear fractures with being in two pairs of cottons, realize quantitative for cotton with this.
After power connection, motor slows down through reducing gear, intermittently rotate by the Geneva mechanism head roll again, cylinder each intermittence, label groove stop place on it can both be on the line of rub wheel center of rotation and cylinder center of rotation, the corresponding groove intermittently staying position of signing is provided with for signing mechanism above cylinder, and there is feed bin in this mechanism and dredges wheel.Sign groove and its bin outlet to timing whenever one, a bamboo let in the feed bin just falls under gravity into to be signed in the groove, and this groove filled and led up, rotation arrival rub wheel position along with cylinder, quantitatively to bamboo let head supply cotton for the cotton machine structure this moment, rub wheel drives bamboo let with the frictional force between its wheel rim and the bamboo let and places at a high speed in signing groove, and cotton sliver is wrapped in its head and rubs with the hands real.The cotton swab that is twisted into leaves the rub wheel position under the carrying of cylinder, next root bamboo let enters this position again, when cotton swab arrives out the label mechanism position with cylinder, by this mechanism cotton swab is transferred to from signing in the groove, and label twisted and finished this moment.
In order to guarantee that rub wheel still can have good the contact with cotton swab after a period of time is used wearing and tearing, be provided with a random back-off mechanism in the kneading mechanism.
In order to prevent that cotton sliver from overstocking, hinder the machine operation, on cylinder, be provided with the residual cotton mechanism that removes.
Compared with the prior art this utility model has the mechanization degree height, prevents that human body from polluting cotton swab, the advantage of cotton swab uniform specification.
Describe enforcement of the present utility model in detail below in conjunction with accompanying drawing.

More than each figure be sketch map.Referring to Fig. 1, this utility model is a power with 25 watts of motor 6, behind the decelerator that constitutes by gear 5,3,4 and 2, drive a Geneva mechanism 22, this mechanism of 23(also claims Geneva wheel Geneva gear), referring to Fig. 3, this mechanism is by crankwheel 23, constitute intermittently rotating mechanism with sheave 22, sheave has four chutes, and crankwheel 23 whenever circles, sheave 22 rotated for 1/4th weeks, and sheave and cylinder 21 are solidly fixed by connecting bolt 28.One middle side part of cylinder is provided with rub wheel 19, and this is taken turns is rubber wheel, drives its continuous rotation by gear 1.Referring to Fig. 2, gear 1 and gear 2 are by idle wheel 26 transmissions, and its middle gear 2,3,4,5 all is installed on machine seat board 27 and 29 through bearing.Referring to Fig. 4 and Fig. 9, cylinder is provided with the label groove 34 of metal, one end of this groove is a cotton swab forming tank 44, and the circumference of cylinder is provided with cotton swab backplate 33, prevents to sign the free landing of cotton swab in the groove, the cylinder opposite side is provided with out label plate 32, this plate is a reed, and the one end is against in the groove 43, and this groove is provided in a side of cannelure on the roll circumference, when cotton swab runs into the label plate, will by its from sign dial in the groove from.The cylinder top also is provided with for signing mechanism, and this mechanism is provided with feed bin 9, dredges wheel 8, and this is taken turns by belt pulley 7,24 and driving belt 25 transmissions, and Geneva mechanism and cylinder are installed on machine seat board 29 and 52 through bearing.Can both make thereon label groove 34 of position be on the line of rub wheel center of rotation and cylinder center of rotation each intermittence of cylinder, and another of 90 degree with interval signed grooves and then be in just for below the outlet of the feed bin 9 of label mechanism.Referring to Fig. 1,5,6,7, the front portion of cylinder is provided with for the cotton machine structure, and the cotton wheel 14,37, two that supplies that is driven rubber by gear 18,20,35 is taken turns with the opposite continuous rotation that turns to for cotton.Rotate with opposite turning to intermittently by gear 17 with its coaxial partial gear 13 transmissions and the disconnected cotton wheel 15 and 36 that makes gear 11,40 drive rubber respectively.When gear 17 rotates, cam 12 and partial gear 13 with its interlock rotate, cam 12 passes through push rod 38 with control stick 10 jack-up, position stop tooth 39 thereon and gear 40 are broken away from, partial gear 13 rotates with gear 11 engagement driven gears 40 simultaneously, thereby the rotation thereupon of disconnected cotton wheel 15,36, cotton sliver is clipped in to be fed forward between the two-wheeled and enters the slit of sending between the cotton wheel 14,37, by sending cotton wheel to be sent to cotton swab forming tank 44.When partial gear turns over certain angle and gear 11 disengaging engagements, cam 12 also forwards minimum point to, and control stick is also locked gear 11,40 by stop tooth 39 under spring 41 effects, 36,15 stalls of disconnected cotton wheel, because send cotton wheel still rotating, then cotton sliver is sent into cotton swab forming tank 44 by tear fracture.
In twisting the cotton swab process, rub wheel will constantly be worn and torn, external diameter constantly diminishes, and the diameter of cotton swab is also different, in order to adapt to above-mentioned situation, guarantee the contact pressure random back-off between rub wheel and the cotton swab, with rub wheel mechanism, be installed on the swing span for cotton machine structure and cotton bucket 16, this is by plate 31,45,46 by securing member 47,48,49 connect firmly and form, this bottom is installed on the wheel shaft 30 of idle wheel 26, can be around axis swing, and do not influence drive connection, and by extension spring device 42 it is connected with machine seat board 52, the pulling force of this extension spring device can be adjusted easily.
In order to prevent from do not have to sign for cotton, excessive in cotton in twisting the process of cotton swab, or residual cotton is trapped in the cotton swab forming tank and causes fault, this utility model is provided with cleaning broach 50 on cylinder, and is provided with on support and removes cotton broach 51, in time the residual cotton in the scavenger.(referring to Fig. 8).
Should be appreciated that this utility model is not limited only to above-mentioned a kind of embodiment, on this basis other subform can also be arranged, do not describe in detail one by one at this.
