Specifically, the bottom surface of the dust-proof glue application roller 7 is the bottom surface of the glue application roller main body 75. The above design facilitates the contact between the raw material to be glued and the bottom surface of the glue application roller main body 75.

[0061] A feeding dust removal mechanism 8 is horizontally assembled on the upper edge of the machine frame 2 on the side close to the feeding end of the conveyor belt 1.

[0062] In some embodiments, in order to shield the feeding and discharging gap after feeding in the spliced dust-proof cover 3 and prevent dust from entering, the lifting shielding member 6 includes:

[0063] A first electric push rod 61 is longitudinally fixedly assembled on the outer wall of the spliced dust-proof cover 3.

[0064] A connecting plate 62, the upper end of which is fixedly assembled on the telescopic lower end of the first electric push rod 61 through bolts.

[0069] A strip-shaped glue storage box body 71;

[0070] Installation plates 72 are vertically and fixedly assembled on the left and right edges of the upper surface of the strip-shaped glue storage box body 71, and the installation plates 72 are fixedly connected to the same side of the inner wall of the spliced dust-proof cover 3 by bolts;

[0071] A valve-equipped glue replenishing pipe 73, which is fixedly communicated with the strip-shaped glue storage box body 71; the strip-shaped glue storage box body 71 is used for storing and transporting glue liquid, and when the glue liquid is insufficient, glue liquid is supplemented from the outside through the valve-equipped glue replenishing pipe 73;

[0072] A strip-shaped shielding frame 77, whose open ends are located on the upper and lower sides, and the upper end of the strip-shaped shielding frame 77 is adhesively fixed to the bottom surface of the strip-shaped glue storage box body 71;

[0073] A glue application roller body 75, the rotating shafts at both ends of which penetrate through the middle parts of the left and right sides of the inner wall of the strip-shaped shielding frame 77;

[0075] The other side rotating shaft of the glue application roller body 75 is rotatably connected to the side of the inner wall of the spliced dust-proof cover 3 away from the driving motor 76; the driving motor 76 is connected to an external power supply, and the driving motor 76 drives the glue application roller body 75 to rotate. The rotating glue application roller body 75 takes out the glue liquid in the strip-shaped glue storage box body 71 from the glue discharge window 74 and applies the taken-out glue liquid to the raw material to be glue-applied;

[0076] A glue discharge window 74 is horizontally opened on the bottom surface of the strip-shaped glue storage box body 71, the upper end of the glue application roller body 75 is inserted into the glue discharge window 74, and the shape of the upper end of the glue application roller body 75 matches the shape of the inner wall of the glue discharge window 74. The lower end of the glue application roller body 75 extends out of the strip-shaped shielding frame 77; the strip-shaped shielding frame 77 shields the outside of the glue application roller body 75, reducing the probability of the glue application roller body 75 contacting dust.

[0077] In some embodiments, in order to scrape off the excess glue liquid on the surface of the glue application roller body 75 and ensure uniform glue application thickness, scraping plate layers 10 are adhesively fixed on the front and rear sides of the inner wall of the glue discharge window 74, and the outer wall of the upper end of the glue application roller body 75 is slidably attached to the scraping plate layers 10.

[0078] In some embodiments, in order to more uniformly store the glue liquid on the surface of the glue application roller body 75 and ensure the glue application amount, glue storage grooves 11 are uniformly opened on the outer wall of the glue application roller body 75.

[0079] In some embodiments, in order to clean the surface dust of the raw material to be glue-applied before glue application, the feeding dust removal mechanism 8 includes:

[0080] A cross plate 81, the two ends of which are fixedly assembled on the upper edge of the frame 2 near the feeding end of the conveyor belt 1 by bolts;

[0081] The upper surface of the horizontal plate 81 is evenly embedded and equipped with fans 82, and the fans 82 are connected in parallel and then connected to an external power supply. The wind force of the fans 82 acts on the upper surface of the feeding end of the conveyor belt 1, and strong wind is used to blow and remove the dust on the surface of the raw material to be coated with glue. When the raw material to be coated with glue is blown by the wind, it slowly moves along with the conveyor belt 1, ensuring that the dust is cleaned more thoroughly.

[0082] In some embodiments, for the convenience of disassembly and facilitating the maintenance and repair of internal components, the spliced dust-proof cover 3 includes:

[0083] Side plates 31, there are two distributed on the left and right, and the two side plates 31 are respectively fixedly connected to the same side of the upper edge of the frame 2 by bolts;

[0084] The U-shaped cover 32, both ends of which are fixedly connected to the left and right side plates 31 by bolts; after removing the bolts, the side plates 31 and the U-shaped cover 32 can be disassembled, and only the U-shaped cover 32 needs to be removed during maintenance and repair.

[0085] In some embodiments, in order to drive the conveyor belt 1 to move up and down, a second electric push rod 9 is evenly and fixedly assembled between the bottom surface of the conveyor belt 1 and the bottom surface of the inner cavity of the frame 2, and the second electric push rods 9 are connected in parallel and then connected to an external power supply; multiple second electric push rods 9 work synchronously to drive the conveyor belt 1 to stably lift.

[0087] The bottom plate 21, on both sides of the upper surface of which vertical plates 22 are fixedly assembled.

[0088] Working principle:

[0089] On the upper surface of the horizontal plate 81 in the feeding and dust-removing mechanism 8, fans 82 are evenly embedded and equipped, and the fans 82 are connected in parallel and then connected to an external power supply. The wind force of the fans 82 acts on the upper surface of the feeding end of the conveyor belt 1, and strong wind is used to blow and remove the dust on the surface of the raw material to be coated with glue. When the raw material to be coated with glue is blown by the wind, it slowly moves along with the conveyor belt 1, ensuring that the dust is cleaned more thoroughly. After dust removal, the raw material to be coated with glue enters the spliced dust-proof cover 3 through the continuous transmission of the conveyor belt 1. The lifting shielding parts 6 on the front and rear sides of the spliced dust-proof cover 3 descend to shield the feeding and discharging gaps, reducing the entry of external dust. The vacuum pump 4 is turned on in time to discharge the dust entering the spliced dust-proof cover 3 due to feeding, and fresh air is inhaled from the air inlet window 5. The fresh air is filtered by the dust-proof filter screen to remove dust, greatly reducing the amount of dust adhering to the surface of the coating roller main body 75 and the raw material to be coated with glue;

[0090] There is a feeding and discharging gap between the upper surface of the conveyor belt 1 and the bottom surface of the spliced dust cover 3. The size of this feeding and discharging gap changes with the lifting of the conveyor belt 1 and meets the glue coating requirements of raw materials with different thicknesses within a certain range.

[0091] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
