[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0029] See also Figure 1-6 A device for gluing cardboard surfaces comprises a rotating chassis 1 fixedly connected to a vertically mounted gantry 2. A linear rotation mechanism 3 is mounted on top of the gantry 2, and a gluing mechanism 4 is connected to the bottom of the movable portion of the linear rotation mechanism 3. Cardboard is attached to the upper surface of the rotating chassis 1. The gluing mechanism 4, working in conjunction with the rotating chassis 1 and the linearly moving linear rotation mechanism 3, applies glue to the cardboard. The linear rotation mechanism 3 can drive the gluing mechanism 4 to move horizontally, vertically, and rotate. The coordinates for gluing must first be converted to polar coordinates.

[0030] The rotating chassis 1 includes: a base plate 101, and the vertical tube of the base plate 101 is rotatably connected to a connecting tube 103. The vertical tube of the base plate 101 and the connecting tube 103 are rotatably connected via a connecting bearing 102, and the top of the vertical tube of the base plate 101 is provided with an annular groove adapted to the connecting bearing 102. The top of the connecting tube 103 is fixedly connected to a hollow rotating adsorption platform 104, and the top plate of the rotating adsorption platform 104 is provided with evenly distributed through holes, and the horizontal tube of the base plate 101 is connected to an exhaust fan 108. Under the suction of the exhaust fan 108, the through holes of the rotating adsorption platform 104 adsorb the cardboard placed above it to prevent the cardboard from moving or tilting during gluing. A foam of a certain thickness can be adhered to the upper surface of the rotating adsorption platform 104 to temporarily limit the cardboard. A first gear 105 is coaxially fixedly mounted on the connecting tube 103. The first gear 105 meshes with a second gear 106, which is coaxially fixedly connected to a first drive motor 107. The bottom of the first drive motor 107 is fixedly connected to the base plate 101. By driving the first gear 105, the first drive motor 107 rotates the second gear 106, causing the connecting tube 103 and the rotating adsorption platform 104 to rotate together.

[0031] The linear rotation mechanism 3 includes: an optical axis 301 fixedly connected to the gantry 2, a screw 302 rotatably connected to the gantry 2, one end of the screw 302 coaxially fixedly connected to a second drive motor 307, and a drive block 303 threadedly connected to the screw 302, and the drive block 303 is slidably connected to the optical axis 301. The second drive motor 307 drives the drive block 303 to move linearly along the optical axis 301 via the screw 302. The bottom of the drive block 303 is fixedly connected to a square frame 304, which encloses an electric telescopic rod 305. The free end of the electric telescopic rod 305 is fixedly connected to a rotary motor 306, and the output end of the rotary motor 306 is fixedly connected to the gluing mechanism 4. The electric telescopic rod 305 drives the gluing mechanism 4 to rise and fall, and the rotary motor 306 drives the gluing mechanism 4 to rotate.

[0032] The end of the screw rod 302 away from the second drive motor 307 is coaxially fixed with a rotary bearing, and the outer ring of the rotary bearing is fixedly connected to the gantry 2. The provision of the rotary bearing improves the stability of the screw rod 302.

[0033] The gluing mechanism 4 includes: a gluing frame 401 fixedly connected to the movable part of the linear rotating mechanism 3, three rollers 402 are rotatably installed in the inner cavity of the gluing frame 401, and the three rollers 402 are arranged in an inverted triangle, a glue storage bin 403 is fixedly installed in the inner cavity of the gluing frame 401, and a lower pressure roller 404 is rotatably installed at the bottom of the inner cavity of the glue storage bin 403, the rollers 402 and the lower pressure roller 404 rotate together and are sleeved with a glue belt 405, two scrapers 406 are fixedly installed on the top of the inner cavity of the glue storage bin 403, which are respectively arranged on both sides of the lower pressure roller 404, and the glue belt 405 passes through the through holes of the two scrapers 406 at the same time.

[0034] The glue storage bin 403 is in the shape of an inverted triangle, and the shape of the glue coating rack 401 is adapted to the glue storage bin 403 .

[0035] The through hole of the scraper 406 is provided with bristles that fit the adhesive tape 405. The bristles of the scraper 406 are used to brush away excess glue on the adhesive tape 405, making the glue layer on the surface of the adhesive tape 405 uniform, thereby making the glue coating on the cardboard uniform and reducing glue dripping when the adhesive tape 405 is applied.

[0036] A liquid level detector 407 is mounted on the inner wall of the glue storage bin 403. A glue supply hose 408, which runs through both the bin 403 and the sidewall of the glue coating rack 401, connects the inner cavity of the bin 403. A glue supply hose is connected to the outer portion of the glue supply hose 408. The rotation angle of the rotary motor 306 is 180 degrees clockwise or 180 degrees counterclockwise to prevent the hose from getting entangled in the glue coating mechanism 4. The liquid level detector 407 is used to monitor the glue level in the glue storage bin 403. If the level is too low, glue is added through the glue supply hose 408 to ensure that the glue in the glue storage bin 403 remains submerged at a level sufficient to submerge the lower pressing roller 404.

[0037] Working principle:

[0038] Before use, a certain thickness of foam is bonded to the upper surface of the rotary adsorption platform 104 to temporarily limit the position of the cardboard. Then, the exhaust fan 108 exhausts air from the horizontal tube of the bottom plate 101. After the cardboard is placed in the middle of the limit frame formed by the foam, the rotary adsorption platform 104 adsorbs the cardboard. Then, the gluing mechanism 4, in cooperation with the rotating rotary chassis 1 and the linearly moving linear rotation mechanism 3, glues the cardboard. The roller 402 of the gluing mechanism 4 is perpendicular to the moving direction of the gluing mechanism 4.

[0039] When the adhesive tape 405 is applying glue to the surface of the cardboard, the adhesive tape 405 rotates under the friction of the cardboard, so that the adhesive tape 405 is continuously dipped in glue in the glue storage bin 403 and then applies the glue to the surface of the cardboard. The bristles of the scraper 406 are used to brush off excess glue on the adhesive tape 405, so that the glue layer on the surface of the adhesive tape 405 is uniform, thereby making the glue coating on the cardboard uniform and reducing the dripping of glue when the adhesive tape 405 is applying glue.

[0040] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, they can make several improvements and modifications without departing from the principles of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
