[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] Reference Figure 1 、 Figure 2 The utility model provides a carton production gluing machine, including a frame 1, on which a hopper 2, a glue rolling mechanism 3, a supporting mechanism 6 and a folding mechanism 5 are installed; a loading and unloading mechanism (not shown) is installed below the hopper 2, a lining plate 7 connected to the hopper 2 is installed below the glue rolling mechanism 3, and a forming cylinder 4 is installed above the folding mechanism 5, and a pressure block that fits the carton is installed on the piston rod of the forming cylinder 4.

[0021] The supporting mechanism 6 includes a supporting plate 601, a guide rod 602 is provided below the supporting plate 601, and a reset spring 603 is provided between the supporting plate 601 and the frame 1 to help the supporting plate 601 reset after the force is dropped; the folding mechanism 5 includes a push rod 501 provided on both sides of the supporting plate 601, and a folding cylinder (not shown) is installed in the frame 1. The folding cylinder drives the push rod 501 to rise and fall through the connecting rod 502, and the guide rod 602 and the connecting rod 502 are respectively provided with a locking rod 604 and an unlocking plate 503 parallel to each other, and a locking mechanism 8 is installed on the frame 1 between the locking rod 604 and the unlocking plate 503.

[0022] During operation, the pressing block on the forming cylinder 4 is above the supporting plate 601, and the gap between the two is greater than the thickness of the cardboard; the loading and unloading mechanism pushes the cardboard 9 from the bottom of the hopper 2 to between the pressing block and the supporting plate 601; the glue rolling mechanism 3 descends and applies glue to the adhesive portion 902 of the cardboard, and at the same time, the folding cylinder drives the folding mechanism 5 to rise and cooperate with the pressing block to fold the side edge 901 of the cardboard upward (refer to Figure 5 After the gluing is completed, the forming cylinder 4 presses the cardboard against the supporting mechanism 6 and pushes it down. The adhesive portion 902 of the cardboard coated with glue is folded upward during the relative movement between the liner 7 and the pressing block. The edge of the liner 7 and the pressing block cooperate with each other to press the adhesive portion 902 against the adhesive ears 903 at both ends of the side edge 901 of the cardboard to bond them together.

[0023] When the forming cylinder 4 pushes the supporting plate 601 to continue to descend until the upper end of the carton is below the push rod 501, the locking mechanism 8 locks the supporting mechanism 6 to the current position through the locking rod 604, and the loading and unloading mechanism installed below the hopper 2 pushes the carton out of the supporting plate 601 to complete unloading. Then the folding mechanism 5 descends and resets and unlocks the supporting mechanism 6 through the unlocking plate 503, so that it can be reset and ready for the next processing.

[0025] When the push rod 501 is lifted, the unlocking plate 503 is in contact with the telescopic tube 803 to push the telescopic tube 803 to move to one side of the locking rod 604 and compress the telescopic spring 804; as the supporting plate 601 is lowered, the locking rod 604 is in contact with the lock tongue 805 to compress the lock spring 806, and then the lock tongue 805 is extended and clamped on the locking rod 604 under the action of the lock spring 806, so that the locking of the supporting mechanism 6 is realized.

[0026] After the blanking is completed, the push rod 501 is lowered to separate the telescopic tube 803 from the unlocking plate 503, and the telescopic tube 803 moves to the direction of the unlocking plate 503 under the action of the telescopic spring 804, so that the lock tongue 805 is separated from the locking rod 604 to realize unlocking.

[0027] Referring to Figure 4 The glue rolling mechanism 3 comprises a lifting rod 301, wherein a top plate 302 is arranged on the top of the lifting rod 301, a lifting cylinder 304 is arranged on the top plate 302, a lifting plate 303 connected with the piston rod of the lifting cylinder 304 is arranged on the lifting rod 301, a motor 305 and a glue box 306 are arranged on the lifting plate 303, a glue roller 307 driven by the motor 305 is arranged below the lifting plate 303, and a glue guide groove 308 is arranged between the glue box 306 and the glue roller 307, so as to ensure that the glue can smoothly flow to the glue roller 307 and be rolled and coated on the paperboard under the driving of the motor 305.
