Specific implementation

[0030] The utility model will be made further detailed explanation in combination with the drawings.

[0031] As Figures 1 to 11 The structure and function of a paper film base paper casting forming device are described in detail below.

[0032] As Figure 1 A paper film base paper casting forming device includes a support 11 and two rollers 21 rotatably connected to the front and rear ends of the support 11 through a bearing with a seat. A base strip 31 is connected between the two rollers 21. A connecting plate 12 is welded to the support 11. A slurry cavity 41 is fixedly connected to the connecting plate 12 by screws. The front end and the lower end of the slurry cavity 41 are both open. An inlet pipe is welded to the upper end of the slurry cavity 41. The slurry is fed into the slurry cavity 41 through the inlet pipe.

[0033] A receiving groove 13 is provided on the connecting plate 12, and the base strip 31 passes through the receiving groove 13. The receiving groove 13 is used to cover and limit the base strip 31. The base strip 31 passes through the bottom of the slurry cavity 41. A servo motor is fixedly connected to the support 11 by screws. The output shaft of the servo motor is connected to one of the rollers 21 through a coupling. When the output shaft of the servo motor starts to rotate, the output shaft of the servo motor drives the roller 21 to rotate through the coupling. The continuous forward movement of the base strip 31 through the bottom of the slurry cavity 41 is driven by the rotation of the roller 21, and the slurry in the slurry cavity 41 is carried away from the slurry cavity 41.

[0034] Further, in order to control the amount of slurry carried away from the slurry cavity 41 when the base strip 31 moves from back to front, as Figure 3 The front end of the slurry cavity 41 is slidably connected to a closing plate 51, as Figure 5 and Figure 7As shown, the sliding mode here is that sliding blocks are fixedly connected on the side of the inner wall of the slurry cavity 41, and sliding grooves are arranged on the side of the closing plate 51, and the closing plate 51 is slidably connected to the sliding blocks through the sliding grooves, so that the closing plate 51 can slide on the slurry cavity 41, thereby controlling the relative distance between the closing plate 51 and the base strip 31, and thereby controlling how much slurry the base strip 31 can take away from the slurry cavity 41;

[0035] Here, as an optimization of the above, a sealing gasket is arranged between the contact position of the side wall of the slurry cavity 41 and the closing plate 51, which can be a rubber gasket commonly used in the prior art to seal, mainly to prevent slurry from flowing out between the side wall of the slurry cavity 41 and the closing plate 51;

[0036] Further, in order to facilitate the lifting of the closing plate 51, a mounting bracket 52 is welded on the closing plate 51, a lead screw I 53 is threadedly connected to the mounting bracket 52, the lower end of the lead screw I 53 is rotatably connected to the slurry cavity 41 through a bearing with a seat, and the lead screw I 53 is in screw transmission with the mounting bracket 52, so that when the lead screw I 53 is rotated, the mounting bracket 52 is lifted in the vertical direction by the screw thread, and the closing plate 51 is lifted by the mounting bracket 52, thereby controlling the relative distance between the closing plate 51 and the base strip 31, and thereby controlling how much slurry the base strip 31 can take away from the slurry cavity 41. The height of the closing plate 51 is fixed by using the one-way transmission characteristics of the lead screw I 53;

[0037] As shown in Figure 1 , 8 and 9, the front end of the closing plate 51 is provided with a plurality of scrapers 61, each of which can be vertically moved to adjust the relative distance between the scraper and the base strip 31, and by controlling the relative distance between the base strip 31 and the scraper 61, the thickness of the film formed is controlled;

[0038] Further, compared with the prior art of providing one scraper 61, a plurality of scrapers 61 are provided side by side in the present application, and the distance between the plurality of scrapers 61 and the base strip 31 decreases from back to front, forming a gradual extrusion of the slurry. Compared with the short distance extrusion of the prior art of one scraper 61, the extrusion of the slurry is completed by one scraper 61 in a short distance, so that the deformation force of the slurry is larger, which affects the film forming quality. The extrusion distance of the slurry is extended by the plurality of scrapers 61, and the extrusion distance of the slurry by each scraper 61 is reduced, so that the deformation force of the slurry is smaller, which ensures the film forming quality;

[0039] The connection between the plurality of scrapers 61 will be described in detail below, as shown in Figure 3As shown, the plurality of scrapers 61 are arranged side by side, the closure plate 51 is provided with a trapezoidal sliding groove I, one side of the scraper 61 is provided with a trapezoidal sliding block, the other side of the scraper 61 is provided with a trapezoidal sliding groove II, the trapezoidal sliding block on one scraper 61 is slidingly connected to the trapezoidal sliding groove II of another scraper 61, and the trapezoidal sliding block on the scraper 61 at the rear side is slidingly connected in the trapezoidal sliding groove I provided on the closure plate 51. Thus, the sliding connection between the plurality of scrapers 61 is completed, so that the plurality of scrapers 61 can move up and down;

[0040] Further, as shown in Figure 8 and Figure 9 The bottom of the scraper 61 is provided with an inclined guide portion, which guides the flow of slurry.

[0041] In order to facilitate the movement of the plurality of scrapers 61, the relative distance between the lower end of the plurality of scrapers 61 and the base strip 31 gradually changes, i.e. from large distance to small distance, forming a gradual guide to the slurry.

[0042] As shown in Figure 8 and Figure 9 The top of the scraper 61 is welded with a sliding column I 62, and the mounting bracket 52 is hinged with a push rod 81. Here, two push rods 81 are provided to consider the balance of force. One end of the push rod 81 is provided with an opening to facilitate the installation of the sliding column 82 II and the sliding column I 62. The plurality of sliding columns I 62 are slidingly connected to the push rod 81. The push rod 81 is slidingly connected with a sliding column II 82. The end of the sliding column 82 II is welded with a limiting plate 83. The limiting plate 83 contacts with the push rod 81. The limiting plate 83 limits the sliding column 82 II, so that the sliding column 82 II cannot rotate, but only slides on the push rod 81. The push rod 81 is rotatably connected with a lead screw II 84 through a bearing with seat. The lead screw II 84 is connected to the mounting bracket 52 through threads. The lead screw II 84 is in screw transmission with the mounting bracket 52. The one-way transmission characteristic of the lead screw II 84 limits the sliding column II 82, so that the sliding column II 82 does not slide when the lead screw II 84 does not rotate.

[0043] When the height of the plurality of scrapers 61 needs to be adjusted, the lead screw II 84 is rotated, and when the lead screw II 84 is rotated, the sliding column II 82 is driven to move up and down through the thread, the sliding column II 82 drives the end of the actuating rod 81 to rotate, so that the actuating rod 81 rotates with the hinged position of the mounting bracket 52, the actuating rod 81 drives the plurality of sliding columns I 62 to move, so that the plurality of sliding columns I 62 move downward, the plurality of sliding columns I 62 drive the scrapers 61 to move downward, the height of the plurality of sliding columns I 62 is positioned by the one-way transmission characteristics of the lead screw II 84, the scraper 61 located at the front end is far away from the hinged position of the actuating rod 81, the radius of rotation of the actuating rod 81 increases from back to front in turn, and then the scraper 61 on the front side moves downward a distance greater than the scraper 61 located on the rear side, so that the plurality of scrapers 61 form an inclined gradient, and the slurry flowing out from the bottom of the closure plate 51 is gradually guided, the plurality of scrapers 61 prolongs the extrusion distance of the slurry, reduces the extrusion distance of each scraper 61 to the slurry, so that the slurry receives a smaller deformation force, and the film forming quality is ensured.
