Description

Technical Field

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

[0002] When cartons are produced, glue is usually applied to the edges of the cardboard to increase the stickiness of the edges of the cartons, prevent the edges of the cartons from cracking or being damaged during handling, transportation and use, and avoid leakage of items inside the cartons. Glue is usually applied to the surface of the carton using a rubber roller. When the glue is transferred to the rubber roller, there is generally an immersion method, in which the rubber roller is immersed in glue. This method is suitable for some viscous glues, but the viscosity of the glue is relatively high, and it may take a long time to drain the excess glue, affecting production efficiency. There is also a spraying method to spray the glue on the rubber roller. The spraying method may produce glue spray, and appropriate ventilation and protective measures are required to prevent the glue from splashing onto the surface of the carton or other parts, which is inconvenient to use.

[0003] Based on the above situation, it is necessary to design a carton production gluing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0026] Reference Figure 1-Figure 7 As shown, a carton production gluing device comprises a gantry 1, a gluing roller 2, a dipping assembly and a controller 3. A glue storage cylinder 11 is connected to the gantry 1. The glue storage cylinder 11 is used for holding water. A leakage groove 12 is provided at the bottom of the glue storage cylinder 11. A placement board 13 is provided at the lower end of the gantry 1. When in use, the cardboards to be glued can be neatly stacked on the placement board 13, and the position to be glued can be placed directly below the gluing roller 2. The gluing roller 2 is connected to the bottom of the gantry 1 through a first telescopic member 21. When the first telescopic member 21 is extended, the gluing roller 2 is connected to the bottom of the gantry 1. When 21 drives the glue coating roller 2 to move downward, the glue coating roller 2 contacts the carton to coat the carton with glue, and the dipping component is used for the glue coating roller 2 to dip the glue in the glue storage cylinder 11. The controller 3 is used to control the flexion and extension of the first telescopic member 21. When the first telescopic member 21 drives the glue coating roller 2 to move downward, the glue coating work is performed, and when the first telescopic member 21 drives the glue coating roller 2 to move upward, the glue dipping work is performed, so that the glue can be dipped again after the glue is coated, avoiding the uneven glue coating caused by the small amount of glue on the glue coating roller 2.

[0027] Furthermore, the dipping assembly includes a blocking seat 4 movably mounted on the leakage groove 12, gears 41 mounted on both ends of the glue coating roller 2, a rack 42 meshing with the gear 41, and a working box 43 connected to the movable end of the first telescopic member 21. The two ends of the glue coating roller 2 extend into the interior of the working box 43 and are rotatably connected to the working box 43. A second telescopic member 44 is provided on the inner top wall of the working box 43. The movable end of the second telescopic member 44 is connected to the top of the rack 42, and the upper end of the working box 43 is provided with a first pressure sensor 45 electrically connected to the controller 3. When the first telescopic member 21 drives the working box 43 to move upward, the glue coating roller 2 is moved upward. The glue roller 2 pushes the blocking seat 4 upwards, so that the blocking seat 4 is separated from the leakage groove 12, so that the glue in the glue storage cylinder 11 can flow out from the leakage groove 12. At the same time, after the first pressure sensor 45 comes into contact with the bottom of the glue storage cylinder 11, the first pressure sensor 45 transmits a pressure signal to the controller 3, and the controller 3 controls the second telescopic member 44 to start driving the rack 42 to move, and drives the glue roller 2 to rotate below the leakage groove 12 through the gear 41, so that the outer peripheral wall of the glue roller 2 is more evenly dipped into the glue, and the lowest point of the working box 43 is higher than the lowest point of the glue roller 2, so as to avoid the contact between the working box 43 and the carton below;

[0028] The first telescopic member 21 and the second telescopic member 44 may be mechanisms such as electric telescopic rods that can perform linear reciprocating motion.

[0029] Furthermore, an arc-shaped groove 7 is provided at the bottom of the glue storage cylinder 11, and a scraper 71 is provided on the inner wall of the arc-shaped groove 7. The arc-shaped groove 7 can reserve a certain space for the glue coating roller 2, so that the glue coating roller 2 can move upward to a greater height without conflicting with the bottom of the glue storage cylinder 11. At the same time, when the glue coating roller 2 moves upward to dip in glue, the scraper 71 contacts the outer wall of the glue coating roller 2, and some of the glue that is dipped on the glue coating roller 2 and hangs on the surface of the glue coating roller 2 can be scraped off, so that the glue dipped on the surface of the glue coating roller 2 is more uniform. At the same time, the scraper 71 is located above the glue coating roller 2. When the glue coating roller 2 is out of contact with the scraper 71 in time, if there is excess glue scraped off on the scraper 71 and it drips, it will also drip onto the glue coating roller 2 directly below, thereby reducing pollution to the carton.

[0030] Furthermore, the upper end surface of the sealing seat 4 is connected to the inner top wall of the glue storage cylinder 11 by an elastic member 5. The elastic member 5 can be a structure with a certain elasticity such as a spring. When the sealing seat 4 is not subjected to the extrusion pressure of the glue coating roller 2, the elastic force of the elastic member 5 exerts a downward force on the sealing seat 4, so that the sealing seat 4 can seal the leakage groove 12 more tightly.

[0031] Furthermore, a connecting frame 8 is provided on the working box 43, a suction cup 81 is provided on the connecting frame 8, and a pump body 82 for providing adsorption force to the suction cup 81 is provided on the connecting frame 8. The pump body 82 can be used as a power source for a vacuum pump, etc., so that the suction cup 81 provides adsorption force, and the cardboard is sucked up for separation by suction, without the need for manual picking up of the cardboard boxes from the neatly stacked boxes. The first pressure sensor 45 is more convenient, and the connecting frame 8 is a retractable structure, which is suitable for adsorbing some longer cardboards.

[0032] The working box 43 is slidably connected to the inner wall of the gantry 1 via a sliding track 6, so that the working box 43 has better stability during the up and down movement.

[0033] Furthermore, a second pressure sensor 9 electrically connected to the controller 3 is provided inside the working box 43, and the second pressure sensor 9 is located directly below the rack 42. When the first telescopic member 21 drives the glue coating roller 2 to move downward and contact the cardboard, the second telescopic member 44 drives the rack 42 to move downward and the rack 42 contacts the second pressure sensor 9. After receiving the signal from the second pressure sensor 9, the controller 3 starts the pump body 82, so that the pump body 82 starts to adsorb the cardboard through the suction cup 81, so that the suction cup 81 has adsorption force only when it contacts the cardboard, thereby preventing the suction cup 81 from providing adsorption force all the time to suck in foreign objects from the outside, affecting the use effect.

[0034] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
