Accompanying drawing explanation
Below in conjunction with accompanying drawing of the present utility model, specific embodiment of the utility model is described in detail:
Fig. 1 is the main TV structure schematic diagram according to the glue spreading apparatus of an embodiment of the present utility model;
Fig. 2 is glue spreading apparatus in the embodiment illustrated in fig. 1 sectional structure schematic diagram along A-A line.
The specific embodiment
Fig. 1 shows according to the glue spreading apparatus of an embodiment of the present utility model.As shown in Figure 1, the glue spreading apparatus in the present embodiment comprises: gluing support 1, upper guide plate 2, lower guide plate 3, glue conveying box 4, glue storage cavity 5, nozzle 6, gluing roller 7.
As can be seen from Figure 1, in the present embodiment, gluing support 1 is a vertical fixed head, represents in the drawings with the square frame of rear side.Upper guide plate and described lower guide plate are all arranged on the side of gluing support 1 towards paper.It it should be appreciated by those skilled in the art that gluing support 1 can also adopt other suitable form, as long as can fix the miscellaneous part in glue spreading apparatus.For the convenience representing, do not draw in the drawings the fixed relationship between the parts such as gluing support and guide plate.
Upper guide plate 2 and lower guide plate 3 toward each other, have predetermined space between the two, form a targeting port for plate, can enter into glue spreading apparatus from this targeting port for the cardboard 8 of processing.This predetermined space is determined according to the thickness of plate, is slightly larger than the thickness of plate.Upper guide plate 2 is positioned at lower guide plate 3 tops.As can be seen from Figure 1, the first end of upper guide plate 2 (being left end) is arcuation, and its first end is upturned, the second end of upper guide plate 2 level substantially, or be slightly inclined upwardly (in figure, left side is inclined upwardly, and right side is a little less than left side).The first end (being left end) of lower guide plate 3 is also arcuation, and is bent downwardly; Second end (being right-hand member) of lower guide plate 3 is level substantially, or slightly tilts to upper right side.
In Fig. 1, the tube of upper right quarter is glue conveying box 4, and as can be seen from the figure, glue conveying box 4 extend in glue storage cavity 5, and glue conveying box 4 one end outwardly can be connected to outside Jiao Yuan, and outside glue source can be that glue conveying box 4 is carried colloid with certain pressure; One end that glue conveying box 4 stretches into glue storage cavity 5 is connected with nozzle 6, and nozzle 6 is flat and points to gluing roller 7.In one implementation, nozzle 6 is arranged on the top of gluing roller 7; In another kind of implementation, nozzle 6 can also be arranged on the sidepiece of gluing roller 6.Preferably, the number of nozzle 6 is multiple, and multiple nozzles are equally spaced arranged on gluing roller 7 sidepieces, are close to gluing roller 7.Alternatively, the switching of multiple nozzles 6 can be controlled separately.If need the wider width of gluing, open multiple nozzles, if need the width of gluing narrower, can opening section nozzle, for example, open one or two 2.
The bottom that glue storage cavity 5 is tubular and glue storage cavity 5 has an opening, gluing roller is placed in glue storage cavity 5 and gluing roller 7 two ends are rotatably installed in respectively the cylinder two ends of glue storage cavity 5 by bearing, and expose outside the opening of glue storage cavity 5 bottom of gluing roller 7.Between the sidewall at the lower openings place of glue storage cavity 5 and described gluing roller, have predetermined space, this predetermined space can be set according to the thickness of wanted gluing, for example, can be set as 1mm, 0.5mm or 0.3mm.
Gluing roller 7 can rotate under the driving of motor, preferably, and the direction rotation that gluing roller 7 can enter towards plate 8.Take the structure shown in Fig. 1 as example, gluing roller 7 is preferably rotated counterclockwise, and the linear velocity of roller circumference equals the speed that cardboard enters.Below gluing roller, bottom roller can also be set, for supporting the plate entering, bottom roller 10 carries out mirror image rotation with gluing roller 7.
Add man-hour carrying out plate, by conveyer, plate 8 is sent in the middle of upper guide plate 2 and lower guide plate 3, due to the shape of upper guide plate 2 and lower guide plate 3, plate 8 can be directed to gluing roller below 7, bottom roller 10 tops.Meanwhile, by glue conveying box, colloid is sprayed on gluing roller 7 by nozzle 6, along with being rotated counterclockwise of gluing roller 7, the colloid being coated on gluing roller is also advanced downwards along roller, and in this process, it is more even that colloid will become.In the time that colloid arrives the opening part of glue storage cavity, owing to having the interval of setting between gluing roller 7 and the opening of glue storage cavity 5 bottoms, therefore, glue storage cavity 5 and gluing roller 7 will form certain extruding to colloid, and then keep the colloid even thickness on gluing roller 7.Preferably, the surface of gluing roller 7 is less than the adsorptivity of plate to colloid to the adsorptivity of colloid, and like this, in the time that plate 8 advances to gluing roller 7 below, gluing roller 7 is attached to the colloidal pressure in roller surface on the surface of plate 8.
In order to guide better plate to enter into gluing roller 7 belows, alternatively, glue spreading apparatus can also comprise a pair of pressurized cylinder 11,12 and pressurization connecting rod 13,14, for controlling respectively upper guide plate 2 and lower guide plate 3.As shown in Figure 1, stretch into pressurized cylinder for pressurization connecting rod 13 one end of upper guide plate 2, the other end is fixed on the upper surface of guide plate 2.Pressurized cylinder 11 exerts pressure to pressurization connecting rod 13, and then controls upper guide plate 2 and move up or down.Similarly, stretch into pressurized cylinder 12 for pressurization connecting rod 14 one end of lower guide plate 3, the other end is fixed on the lower surface of lower guide plate 3.Pressurized cylinder 12 exerts pressure to pressurization connecting rod 14, and then controls lower guide plate 3 and move up or down.
Alternatively, the glue spreading apparatus in the present embodiment can also comprise spring 15 and spring 16, and spring 15 is fixed on guide plate, returns to origin-location in order to offset gravity or the auxiliary upper guide plate that upper guide plate receives.Similarly, spring 16 is fixed on lower guide plate, realizes similar function.In this implementation, the right-hand member of two guide plates can be provided with rotating shaft, and the left end of guide plate can be rotated around rotating shaft.
By adopting pressurized cylinder 11,12 and pressurization connecting rod 13,14, can control better the two motion of guide plate 2 and lower guide plate 3, and then control better the position that plate 8 enters, guarantee that plate 8 is just between gluing roller 7 and bottom roller 10, and realize fixing to plate.
Fig. 2 looks from right side along the A-A line in Fig. 1, the sectional structure schematic diagram of glue spreading apparatus.As can be seen from Figure 2, nozzle 6 comprises multiple small nozzles, between adjacent two small nozzles, has predetermined interval.The width of bottom roller 10 is greater than the width of gluing roller 7, and this is in order to guarantee that the plate 8 for the treatment of gluing supports better, and avoids plate to deform under the pressure-acting of gluing roller 7.
In the present embodiment, glue spreading apparatus can also comprise pay-off (not shown), and this pay-off drives and treats that the plate of gluing enters glue spreading apparatus between upper guide plate 2 and lower guide plate 3.
It should be noted that; the shape of all parts in accompanying drawing of the present utility model is all schematic; there is some difference not get rid of itself and its true shape; accompanying drawing is only for principle of the present utility model is described, and the detail of parts shown in figure is the restriction to utility model protection scope not.Those skilled in the art also should be appreciated that, above-described embodiment is only also the explanation to schematic implementation of the present utility model, not the restriction to the utility model scope.
