The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0032] First embodiment

[0033] like Figure 1-Figure 5 As shown, the glue coating device of the first embodiment of the utility model comprises:

[0034] Glue slot 1, the glue slot 1 is arranged horizontally with the slot facing upward;

[0035] The rubber roller 2 extends along the length direction of the rubber groove 1 and is arranged to rotate around its own axis. The rubber roller 2 is a floating roller intersecting with the notch of the rubber groove 1;

[0036] The roller seat 3 is arranged at both ends of the rubber roller 2 and is rotatably connected to the rubber roller 2. The roller seat 3 is slidably connected to the rubber groove 1 along the vertical direction.

[0037] Different from the prior art, in the present embodiment, the rubber roller 2 is a hollow floating roller, which is placed in the rubber groove 1. The two ends of the rubber roller 2 are connected to the roller seat 3, and the lower part of the rubber roller 2 is in contact with the glue liquid in the glue groove 1. As the rubber roller 2 rotates, the glue is carried and smeared on one side of the film material 5 passing through its upper part. As the glue coating proceeds, the amount of glue in the glue groove 1 decreases, and the rubber roller 2 descends as the glue liquid level drops. The roller seat 3 is slidably connected to the rubber groove 1 in the vertical direction to ensure that the axis of the rubber roller 2 stably descends in the vertical direction. Since the rubber roller 2 can descend as the liquid level drops, the fixed contact area between the rubber roller 2 and the glue liquid in the glue groove 1 is guaranteed, which is conducive to smearing a fixed amount of glue on the surface of the film material 5, and avoids the rubber roller 2 smearing glue The amount of glue is reduced due to the reduced contact area with the glue liquid after the height position of the rubber roller 2 remains unchanged. This is beneficial to improving the production quality of the composite film.

[0038] In order to achieve stable sliding cooperation between the roller seat 3 and the glue groove 1, in this embodiment, a guide rod 34 extending upward in the vertical direction is provided above the roller seat 3, a guide sleeve 12 is fixed on the glue groove 1, the guide rod 34 is slidably connected to the guide sleeve 12, and the guide rod 34 is fixedly connected to a distance sensor 13 located directly above and downward from the guide sleeve 12.

[0039] Specifically, the top two ends of the glue groove 1 are integrally connected with a horizontal extension plate 11, the guide sleeve 12 is oval in shape, one end of which is fixed above the extension plate 11, and the other end is slidably matched with the guide rod 34, and a bracket 14 is fixed to the top of the guide rod 34, and the distance sensor 13 is installed on the bracket 14.

[0040] After adopting the above structure, the sliding cooperation between the guide sleeve 12 and the guide rod 34 ensures the stable movement of the roller seat 3 in the vertical direction, which is beneficial to ensure the stable movement of the rubber roller 2 in the vertical direction; in addition, a downward distance sensor 13 is set at the top of the guide rod 34 through the bracket 14, and the distance sensor 13 is used to detect the height distance between the bracket 14 and the guide sleeve 12, so as to facilitate the detection of the glue level in the glue groove 1. When the amount of glue is too little, the staff can replenish glue in the glue groove 1 in time.

[0041] A further improvement is that a guide roller 4 located just above the bottom of the rubber groove 1 is provided on the feed side and / or the discharge side of the rubber roller 2, and both ends of the guide roller 4 are connected to the roller seat 3; further, guide rollers 4 are provided on both the feed side and the discharge side of the rubber roller 2.

[0042] After adopting the above structure, the guide rollers 4 on both sides of the rubber roller 2 can guide the transmission movement path of the film material 5, thereby fixing the contact area between the film material 5 and the rubber roller 2. On this basis, since the contact area between the rubber roller 2 and the glue in the glue tank 1 is fixed, it can ensure that a glue layer with uniform thickness is formed on the film material 5, which is beneficial to improving the production quality of the composite film.

[0043] A further improvement is that the roller seat 3 is also provided with a slide rod 31 extending upward in the vertical direction, an adjustment seat 32 is slid on the slide rod 31 along its own length direction, the adjustment seat 32 is connected to the guide roller 4, and a locking assembly 33 is provided between the adjustment seat 32 and the slide rod 31, and the locking assembly 33 is used to lock the adjustment seat 32 in at least two working positions.

In this way, by changing the working position of the guide roller 4, the transmission path of the film material 5 can be changed, and then the contact area between the film material 5 and the rubber roller 2 can be changed, so that the amount of glue applied on the surface of the film material 5 can be adjusted according to needs.

[0045] Specifically, the slide rod 31 is provided with first jacks 311 distributed along its length direction, the adjustment seat 32 is provided with second jacks 321 , the locking assembly 33 includes a locking pin 331 , and the second jack 321 is plugged and matched with one of the first jacks 311 through the locking pin 331 .

[0050] Third embodiment

[0051] like Figure 8 and Fig. 9 As shown, the gluing device of the third embodiment of the utility model is based on the second embodiment, and the difference is that the locking assembly 33 includes a locking screw 332 and a locking screw tube 334 that are threadedly connected, and the locking screw tube 334 is fixed on the adjustment seat 32. In the locked state, the locking screw 332 abuts against the sliding rod 31.
