Description

Technical Field

[0001] The utility model relates to the technical field of carton production, in particular to a carton gluing device for evenly gluing. Background Art

[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. When producing cartons, a gluing device is required for gluing.

[0003] During the production process of cartons, the cardboard will be glued and then assembled. When gluing the existing cardboard, it is easy to have uneven glue coating, which is not only inefficient and causes waste of glue, but also affects the coating quality of the product.

[0004] As disclosed in Chinese patent CN213727505U, a gluing device for carton production with a uniform gluing function is proposed. The cardboard to be glued is placed on the conveyor belt, the cardboard is located between the conveyor belt and the glue wiping board, and then the motor is started. The motor rotates to drive the rotating shaft to start rotating, the rotating shaft rotates to drive the sleeve to rotate, and the sleeve rotates to drive the conveyor belt to start rotating. The cardboard slowly moves forward with the rotation of the conveyor belt, and at the same time, several glue outlets on the glue storage box are controlled to slowly drip glue downward. When the cardboard moves to the bottom of the glue outlet, the glue just drips. After the entire cardboard is dripped with glue, the glue outlet stops discharging glue, and then the slide bar is controlled to slide forward in the direction of the slide slot. At this time, the glue wiping board moves forward at the same time, so that the glue on the cardboard can be evenly coated. After coating, the slide bar is controlled to move backward in the direction of the slide slot.

[0005] However, the glue coating device used in the above-mentioned comparative document adopts the glue dripping method. When the glue drips on the surface of the cardboard, it will cause a round drop shape and cannot evenly cover the surface of the cardboard. If the density is increased, it is easy to have excessive glue and overflow the cardboard.

[0006] For this reason, we urgently need to provide a carton gluing device with uniform gluing. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0027] Embodiment 1:

[0028] A carton gluing device with uniform gluing comprises a supporting leg 1, a conveying structure is installed on the top of the supporting leg 1, a glue brushing structure is installed on the left side of the top of the conveying structure, and an anti-gel structure is installed on the right side of the glue brushing structure.

[0029] The glue-brushing structure includes a glue-brushing unit and a cleaning unit. The glue-brushing unit includes a liquid pump 201, the output end of the liquid pump 201 is connected to a delivery pipe 202, a connection block 203 is installed on the outer surface of the delivery pipe 202 at one end away from the liquid pump 201, a spring 1 204 is connected to the bottom surface of the connection block 203, a mounting plate 205 is connected to the bottom end of the spring 1 204, a glue-spreading wheel 206 is installed on the bottom surface of the mounting plate 205, and a spray port 207 is connected to the top of the outer surface of the glue-spreading wheel 206. The cleaning unit includes a brush 208, a sliding rod 209 is installed in the middle of the top surface of the brush 208, and a spring 2 210 is installed in the middle of the top surface of the brush 208.

[0030] The end of spring 210 away from the brush 208 is fixedly connected to the left end in the middle of the bottom surface of the mounting plate 205, the outer surface of the sliding rod 209 is slidably connected to the inside of a circular hole in the middle of the top surface of the mounting plate 205 near the left end, the top of the spray port 207 is connected to the end of the delivery pipe 202 away from the liquid pump 201, and the output end of the spray port 207 is slidably connected to the outer surface of the glue coating wheel 206.

[0031] The conveying structure includes a workbench 101, a conveyor belt 102 is installed in the middle of the top surface of the workbench 101, a support frame 103 is installed on the top surface of the workbench 101, and an electric push rod 104 is installed in the middle of the top surface of the support frame 103 near the left end. The bottom surface of the workbench 101 is fixedly connected to the top of the support leg 1, the conveyor belt 102 is installed in the installation groove opened in the middle of the top surface of the workbench 101, and the output end of the electric push rod 104 is connected to the middle of the top surface of the mounting plate 205.

[0032] By setting the glue brushing structure, the spray port 207 can be used to evenly apply glue to the outer surface of the glue coating wheel 206, so that the rotation of the glue coating wheel 206 can evenly apply glue to the surface of the cardboard, and before gluing, the brush 208 can be used to clean the dust on the surface of the cardboard to prevent affecting the adhesion effect of the glue.

[0033] The cardboard is placed on the top of the conveyor belt 102, and then the conveyor belt 102 is started to convey the cardboard. At the same time, the electric push rod 104 is started to drive the mounting plate 205 to rise and fall, thereby adjusting the height of the brush 208 and the glue coating wheel 206 to adapt to cardboards of various thicknesses. The bottom of the brush 208 is brought into contact with the surface of the cardboard to clean the dust on the surface of the cardboard, and the liquid pump 201 is started to convey the glue through the conveying pipe 202.

During the process of brushing and cleaning, the contact force between the brush 208 and the cardboard is used to drive the sliding rod 209 to slide inside the through hole opened in the mounting plate 205, thereby stretching the spring 210, and applying a reaction force by utilizing the deformation stress, so as to achieve a better cleaning effect. Similarly, by utilizing the tensile stress of the spring 1 204, the glue coating wheel 206 can be brought into contact with the surface of the cardboard, making the glue coating more even.

[0034] Embodiment 2:

[0035] On the basis of the first embodiment, the anti-gel structure includes a heating box 301, a heating frame 302 is installed inside the heating box 301, a heating tube 303 is installed inside the heating frame 302, a fan 304 is installed at the left end of the middle of the top surface of the heating box 301, an impeller 305 is arranged on the left side of the fan 304, a rotating shaft 306 is installed in the middle of the bottom surface of the impeller 305, and a stirring wheel 307 is installed at the bottom end of the rotating shaft 306, a liquid box 308 is arranged on the left side of the heating box 301, and a liquid inlet pipe 309 is installed in the middle of the top surface of the liquid box 308.

[0036] By setting up the anti-gel structure, the heating tube 303 installed inside the heating box 301 can heat the liquid box through the ventilation hole opened on the left side of the heating box 301, so that the glue inside the liquid box is maintained in a certain temperature range to prevent the glue from solidifying. The fan 304 blows the impeller 305 to drive the rotating shaft 306 and the stirring wheel 307 to rotate, stir the glue, and prevent the glue from solidifying.

[0037] By turning on the heating tube 303, the temperature inside the heating box 301 can be increased, and the heat can be transferred to the left side by using the ventilation holes on the left side of the heating box 301, thereby ensuring that the glue inside the liquid tank 308 is kept in a certain temperature range to prevent solidification. At the same time, the fan 304 is started to blow the impeller 305, so that the impeller 305 drives the rotating shaft 306 to rotate, thereby driving the stirring wheel 307 to stir the glue inside the liquid tank 308, thereby effectively preventing the glue from solidifying.
