Embodiment

Below in conjunction with accompanying drawing the utility model is specified.

Fig. 1 represents the schematic diagram of intermittent solutioning mechanism of the present utility model.As shown in the figure, this intermittent solutioning mechanism 120 comprises base wheel 26 and belt wheel 20, scribble slurry on the base wheel 26 and drive rotation by basic turbin generator, belt wheel 20 drives rotation by belt wheel motor, base band is coated on the belt wheel 20 and by frictional force and belt wheel 20 with certain cornerite and is synchronized with the movement, and base wheel 26 can be in contact with one another with belt wheel 20 and separate, and realizes the batch (-type) pasting to base band.

Preferably, this intermittent solutioning mechanism 120 also comprises magazine 17, keeps the scraper 19 of certain interval and the adjusting rod 18 that is connected with scraper 19 with base wheel 26, and the bottom of wherein said base wheel 26 is immersed in the described magazine 17, so that pasting on base wheel 26.In addition, for the person of ordinary skill of the art,, also can adopt in the prior art other technical scheme, for example directly on base wheel 26, spray slurry, perhaps directly slurry be flowed to base wheel or the like by the slurry supply pipe for pasting on base wheel 26.When base wheel 26 drove rotation by basic turbin generator (not shown), slurry can adhere on the base wheel 26 and by scraper 19 and scrape off redundant sizing agent, made the slurry on the base wheel 26 keep certain thickness.Adjusting rod 18 on the scraper 19 can be regulated vertical height of scraper 19, so that regulate the gap length between scraper 19 and base wheel 26 outer surfaces, thereby can regulate the thickness of base wheel 26 spreading masses, the pasting thickness on the control base band.Base band is coated on the belt wheel 20 with the cornerite of certain cornerite as 90 degree or 180 degree.The material of belt wheel 20 generally is a polyurethane, so by the frictional force between belt wheel 20 and the base band, when belt wheel drives rotation by belt wheel motor, can drive base band and be synchronized with the movement.

Base wheel 26 can be in contact with one another with belt wheel 20 and separate, and when they contacted with each other, the slurry on the base wheel 26 just bat printing was realized the pasting operation to base band on the base band that is coated on the belt wheel 20; When they separated, 26 idle running of base wheel can pasting on base band, thereby realized the batch (-type) pasting to base band.

When base wheel 26 contact with belt wheel 20, if basic rotating speed of taking turns 26 rotating speed greater than belt wheel 20, then the pasting thickness on the base band was thicker; If the rotating speed of base wheel 26 is less than the rotating speed of belt wheel 20, then the pasting thickness on the base band is thinner relatively.Thus, by regulating the rotating speed of base wheel 26, can further regulate the thickness of pasting on the base band.

Base wheel 26 can adopt multiple scheme to realize with contacting with each other of belt wheel 20 with separating, and for example is connected on the base wheel 26 by a cylinder or is connected on the belt wheel 20 or adopts other actuating mechanism or the like.Shown in Fig. 1 is to be connected with belt wheel 20 by cylinder 21, by horizontal mobile belt wheel 20, realize between belt wheel 20 and the base wheel 26 contact with separate.The action of cylinder 21 can be controlled by computer.Particularly, the pasting position transducer can be set near belt wheel 20, this transducer can be used for detecting the length of pasting on the base band as required, if the one side of base band has scribbled slurry, can also be used to detecting the position that has been coated with slurry, then testing result is transferred in the computer and handles, come mobile belt wheel 20 by computer control cylinder 21 then, control the length of pasting on the base band and the length of not pasting then.Control the common practise that the cylinder action belongs to automation control area by computer programming, so do not describing in detail at this.

In addition, operate steadily in order to make base band, in solutioning mechanism 120 constant tension mechanism 121 can be set, this constant tension mechanism 121 comprises floating roller 23 and position transducer 28.Floating roller 23 is suspended on the base band, owing to the acting in conjunction that is subjected to gravity and base band tension force is suspended in the centre position, position transducer 28 detects the position and the acceleration of floating roller 23, and testing result is transferred to computer, this computer is handled testing result, then by the rotating speed of controller control belt wheel 20, makes the position of floating roller 23 keep constant and acceleration is zero, thus, the gravity of the tension force of base band and floating roller 23 keeps balance.In this case, it is constant that the tension force in the base band keeps, and operates steadily.

As shown in Figure 2, the utility model also provides a kind of two-sided emulsion coating machine, comprise having unreeling structure 110 that unreels motor and rolling-up mechanism 150 with winding motor, and two solutioning mechanisms 120 that between described unreeling structure 110 and rolling-up mechanism 150, are provided with.

In this two-sided emulsion coating machine, base band discharges from unreeling structure 110, enter into a solutioning mechanism 120 then, and then enter into second solutioning mechanism 120, it is standby to enter into rolling-up mechanism 150 rollings at last, wherein unreeling structure 120 and rolling-up mechanism 150 belong to the shared device of this area, and are not invention of the present utility model places, so at inferior its concrete structure that repeats no more.

In addition, in this embodiment, because slurry generally need carry out drying, so baking sheet mechanism generally need be set therein.As shown in the figure, positive baking sheet A of mechanism and the reverse side baking sheet B of mechanism are set respectively in the downstream of described two solutioning mechanisms 120, and the purpose in order to simplify the internal structure of an organization, positive baking sheet A of mechanism and the reverse side baking sheet B of mechanism integrate and constitute a baking sheet mechanism 130.Certainly, according to the restriction or the site requirements of condition of work, also can adopt two independently positive baking sheet A of mechanism and the reverse side baking sheet B of mechanism fully.

Preferably, base band discharges from unreeling structure 110, enter into solutioning mechanism 120 and carry out positive pasting, enter into the positive baking sheet A of mechanism then and dry slurry, then enter into second solutioning mechanism 120 and carry out the reverse side pasting, and then turn back to the reverse side baking sheet B of mechanism and dry, baking sheet temperature can determine according to technological requirement, dries base band behind the slurry at last and enters into rolling-up mechanism 150 rollings and get up standby.

Preferably, in the running of base band, do not wander off in order to guarantee base band, can in unreeling structure 110 and rolling-up mechanism 150 the deviation correction mechanism (not shown) be set respectively, deviation correction mechanism can adopt deviation correction mechanism commonly known in the art, this no longer auspicious stating.

In addition,, also can auxiliary deviation correction mechanism be set between each station or between some station, to guarantee base band stabilized walking and not wandering off in whole pasting process if production line is long.As can be seen from the figure, before rolling-up mechanism 150, be provided with an auxiliary deviation correction mechanism 160, but this not necessarily.

In order to guarantee the stability of base band in whole pasting process, except constant tension mechanism 121 is set, can also constant tension mechanism 151 be set before rolling-up mechanism 150 in solutioning mechanism 120, be used to control the rolling speed of rolling-up mechanism 150.Constant tension mechanism 121 is identical with constant tension mechanism 151 structures, repeats no more.

According to embodiment the utility model is specifically described above, but those skilled in the art will appreciate that above-mentioned concrete description is not for limiting protection range of the present utility model.For example, do not wander off in running in order to guarantee base band, can in unreeling structure or in the rolling-up mechanism or in other stations or between the station deviation correction mechanism be set, therefore, the quantity of deviation correction mechanism can be decided according to technological requirement.In addition, for some other member such as the transition wheel in the emulsion coating machine of the present utility model, motor or the like does not carry out too much description, because they belong to the common practise in this area, and does not belong to inventive point of the present utility model.
