Description

Coating device

The utility model relates to and utilize roll-type to reverse viscose is coated in a kind of apparatus for coating on the base material equably.

Existing reverse roll-type apparatus for coating is mainly by carry-over pinch rolls, coating roll, three roller reversion types that metering roll is formed and be added with two kinds of the four roller reversion types that feed roller forms outward, gluing containing disk is arranged at the bottom of coating roll or feed roller, base material is by between carry-over pinch rolls and the coating roll during crack, and coating roll is coated on viscose on the base material.But there is following several problem in above-mentioned apparatus for coating: fixedly connected formula is all adopted in the arrangement of (1) several rollers, and three roller reversion types and four roller reversion types can not exchange easily, and the scope of application is little, and the quality that different glue kinds are coated with differs bigger; (2) roller is that speed and mutual gap are difficult to adjust, the quality of coating is affected easily, the scope of application is also little, (3) adopt the rotation of each roller of driven by motor or every roller all independent by a driven by motor, the former can't realize wiping than stepless speed regulation, stops in case requiring base material to carry, and coating roll and other roller also will stop, so easily with paint adhesion on roller, influence coating quality; The latter then increases cost, and effect is also bad; (4) the existing roll-type apparatus for coating that reverses all is used in the big-and-middle-sized coating apparatus independently, be difficult on the small-sized coating machine use, and apparatus for coating can not be replaced by other coating method.

The purpose of this utility model is exactly in order to overcome the shortcoming of above-mentioned existence, to provide a kind of easy to use, applied widely, and coating quality is reliable, and volume is little, the small-sized apparatus for coating that cost is low.

The purpose of this utility model is finished by following technical solution, on the two axial ends of feed roller, slide block is housed, about being placed on then in the feed roller slideway of two wallboards, the bottom has seat board to be screwed on wallboard, also be provided with adjusting screw(rod) on the seat board, in order to regulate the upper-lower position of feed roller; Gluing containing disk is by being arranged on the bottom that adjusting screw(rod) on the bearing is placed in feed roller, because seat board can unload easily, and gluing containing disk can be by adjusting screw(rod) its position of rising, so, four roller reversion type dispense tips can be transformed to three roller reversion type dispense tips easily, with the coating of low viscosity glue in adapting to.The utility model also adopts following proposal further to realize, slide block is housed on the two axial ends of carry-over pinch rolls and is placed in the slideway of wallboard, the top of slide block has been close to the compression spring, the outer top of slideway is provided with the regulating handle that compresses that links to each other with slide block, between carry-over pinch rolls and coating roll axle bed, be provided with the adjusting skewback, and be connected with adjusting screw(rod).Carry-over pinch rolls of the present utility model and coating roll are respectively respectively by a driven by motor, metering roll, feed roller then link to each other with the gear of coating roll with the idler gear structure by regulating exchange, thereby traction is separated with the power of coating, and the realization wiping is improved the quality of products than stepless speed regulation.

Description of drawings is as follows:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a sectional structure schematic diagram of the present utility model.

Below will the utility model is further introduced by accompanying drawing.The utility model mainly by about two wallboards 1, carry-over pinch rolls 2, coating roll 3, metering roll 4, feed roller 5, gluing containing disk 6 compositions such as grade, there are bearing 7 and slide block 8 in the two ends of carry-over pinch rolls 2, and are placed in the slideway on the wallboard, and the top of slide block 8 is connected with compression spring 9, and be connected with outward and compress regulating handle 10, the axle head of carry-over pinch rolls 2 also is equipped with the sprocket wheel 11 that links to each other with motor; In the outside of carry-over pinch rolls 2, the inboard of wallboard 1 is equipped with coating blade 12 respectively, and has adjusting nut 13 to be attached thereto, to regulate the width of coating; The bottom of adjacent carry-over pinch rolls 2 is provided with coating roll 3, it is placed on the wallboard 1 by diaxon bearing at end 14, end at axle has motor rotating sprocket 15 and feed roller travelling gear 16, the other end then is equipped with metering roll travelling gear 17, be provided with one and regulate skewback 18 between the bearing block of carry-over pinch rolls 2 and coating roll 3, this regulates the skewback 18 outer adjusting screw(rod)s 19 of ining succession; The outside of coating roll 3 is adjacent metering roll 4, it also is placed in respectively on the wallboard 1 by two bearings 20, there is travelling gear to match with metering roll drive 17 at the one axle head by a change gear group 21, the roller edge outside of metering roll 4 is provided with and cleans scraper 22, and this scraper is placed in to be scraped on the tool rest 23, scrape 23 of the tool rests adjusting nut 24 of ining succession, in order to regulate the position of scraper 22, it is used to clean the viscose on the metering roll as required.The below of adjacent coating roll 3 is provided with feed roller 5, its two ends are placed in the slideway of wallboard 1 by bearing 25 and slide block 26, the bottom is supported with seat board 27 and adjusting screw(rod) 28 and is fixing, seat board 27 is screwed on wallboard 1, can dismantle, one end of feed roller 5 has travelling gear 29, this travelling gear 29 matches with feed roller travelling gear 16 on the coating roll 3 by a transition gear 30, the below that the outside of transition gear 30 is connected with an adjusting nut 31 feed rollers 5 is provided with gluing containing disk 6, it relies on Sheng glue frame 32 that is fixed on two wallboards 1 and the adjusting screw(rod) of containing on the glue frame 32 33 supporting, above-mentioned apparatus for coating is set up separately, adopts two motors to drive carry-over pinch rolls 2 and coating roll 3 respectively.To compress regulating handle 10 upsets during use earlier, carry-over pinch rolls 2 are mentioned, base material 34 is passed between carry-over pinch rolls 2 and coating roll 3, then, regulating handle 10 restores, and more as required, adjusts and regulates skewback 18, makes the gap between carry-over pinch rolls 2 and the coating roll 3 reasonable; Starting the coating roll motor rotates coating roll 3, because the transmission of gear pair engagement, metering roll 4 and feed roller 5 also rotate thereupon, because of the bottom of feed roller 5 is immersed in the gluing containing disk 6, so bring coating roll 3 with viscose when it rotates, and the glue on the coating roll 3 is controlled glue-line and dope layer by adjusting metering roll 4 with the gap of coating roll 3 and the relative velocity of two rollers, make and keep a coating content accurately on the coating roll 3, make glue can be coated on the surface of base material equably, start the carry-over pinch rolls motor, base material 34 is under the drive of carry-over pinch rolls 2, constantly pass through between carry-over pinch rolls 2 and the coating roll 3, constantly coat viscose, when adopting the coating of three roller reversion types, only need the screw on the seat board 27 of feed roller 5 is twisted and unloaded, can be with feed roller 5 together with feed roller slide block 26 suitable slideway overall pulling downs, by adjusting adjusting screw(rod) 33 gluing containing disk 6 is risen on the coating roll 3 immersion glues gluing containing disk 6 then, can reach the function of three roller reversion types coating.The utility model can be set up separately, and dismounting and can also be pulled down as required and adopt other coating method on coating apparatus on coating apparatus easily.

The utility model compared with prior art has simple in structurely, easy to use, and the glue kind that is suitable for is many, and scope is wide, the reliable in quality of coating, the characteristics such as volume is little, and cost is low.
