[0016] The following will be described in detail with reference to the accompanying drawings Figs. 1-3 The application will be further described in detail.

[0017] The embodiment of the application discloses a uniform pushing device of a carton nailing machine. Figs. 1-3 The uniform pushing device of the carton nailing machine mainly comprises a conveying roller line 1, a nailing device 2, an adjusting bracket 3 and a guide assembly 4, realizes accurate positioning, stable pushing and efficient nailing of the carton, and effectively protects the paperboard.

[0018] Referring to Fig. 1 The conveying roller line 1 is made of high-strength carbon steel material as the basic conveying component of the whole device. The frame of the conveying roller line 1 is assembled in a welded or bolted manner, and this connection mode ensures that the frame has sufficient strength and rigidity.

[0019] Referring to Fig. 2 The nailing device 2 selects a mature carton nailing machine head on the market, which is installed on the conveying roller line 1 through the gantry, and the connection between the nailing device 2 and the conveying roller line 1 is firm and reliable, which ensures that the nailing device 2 will not shift due to vibration during nailing, and ensures the stability of the nailing operation.

[0020] Referring to Fig. 2, the adjusting bracket 3 is located at the feeding end of the conveying roller line 1, and includes a gantry 301, a telescopic cylinder one 302 and a guide strip 303. The gantry 301 is made of aluminum alloy, which fully utilizes the characteristics of light weight and high strength of aluminum alloy, greatly facilitates the installation and adjustment work. The size of the cross beam and the column is carefully designed according to the moving range of the guide strip 303 and the bearing requirement, to ensure that the telescopic cylinder one 302 and the guide strip 303 can be stably supported, and to provide a solid frame foundation for the accurate movement of the guide strip 303. The telescopic cylinder one 302 selects high-precision hydraulic or pneumatic cylinder, the stroke is designed according to the maximum thickness difference of the carton, and the diameter of the piston rod is accurately calculated to ensure that it can bear the weight of the guide strip 303 and the carton, and it is stable and accurate during the telescopic process, without jamming or shaking phenomenon. Through the driving of the telescopic cylinder one 302, the guide strip 303 can move flexibly along the Z-axis direction, when the carton is placed at the feeding end of the conveying roller line 1, the position of the guide strip 303 can be quickly adjusted according to the thickness of the carton, so that it maintains a proper distance with the bottom of the carton, provides bottom support and accurate guidance for the carton, avoids the carton from shaking up and down during the conveying process, and ensures the accuracy of the subsequent nailing operation. The guide strip 303 is made of stainless steel and is polished on the surface to effectively prevent scratching the carton, when the carton reaches below the nailing device 2, it plays a separating and guiding role for the folded carton, and after the nail penetrates the paperboard, the guide strip 303 can bend and shape the nail to prevent the nail from damaging the paperboard, and fully protect the quality of the carton.

[0021] With reference to Fig. 2 and Fig. 3The guiding assembly 4 is arranged on both sides of the guide strip 303 of the conveying roller line 1, and includes a telescopic cylinder two 401, a support frame 402 and a conveying belt 403. The telescopic cylinder two 401 also selects a high-precision hydraulic or pneumatic cylinder, and the stroke is designed according to the maximum width difference of the carton, and cooperates with the telescopic cylinder one 302 to realize accurate positioning of the conveying belt 403. When adjusting according to the width of the carton, the telescopic cylinder two 401 drives the support frame 402 to drive the conveying belt 403 to move along the X-axis direction, so that the conveying belt 403 is closely matched with the guide strip 303 to stably clamp and convey the upper and lower sides of the carton. The support frame 402 is made of aluminum alloy or carbon steel, has a reasonable structure design, can firmly install the roller 4031 and the synchronous belt 4032, and is convenient for subsequent adjustment and maintenance work. The roller 4031 of the conveying belt 403 is made of rubber or polyurethane material, and has good friction and wear resistance. The synchronous belt 4032 is made of high-strength rubber material, and the tooth shape is accurately matched with the roller 4031, so that the transmission is accurate and efficient. The width of the synchronous belt 4032 is designed according to the maximum width of the carton, which ensures that the synchronous belt 4032 can fully contact the side of the carton, realizes stable clamping and conveying of the carton, and further enhances the stability of the carton in the conveying process, and provides strong guarantee for accurate nailing. The distance measuring sensor arranged on the support frame 402 selects a laser distance measuring sensor or an ultrasonic distance measuring sensor, which can quickly and accurately measure the thickness and width of the carton, and provide reliable data support for the control system. The control system drives the telescopic cylinder one 302 and the telescopic cylinder two 401 to adjust in time and accurately according to the data, and realizes self-adaptive pushing of cartons of different sizes.

[0022] The implementation principle of the uniform pushing device of the carton nailing machine in the embodiment of the application is as follows:

[0023] In use, when the carton is placed on the feeding end of the conveying roller line 1, first, the position of the guide strip 303 is adjusted by the telescopic cylinder one 302 according to the thickness of the carton, to provide bottom support and guidance for the carton. At the same time, the conveying belt 403 is driven to move by the telescopic cylinder two 401 according to the width of the carton, so that it is matched with the guide strip 303 to clamp and convey the carton. When feeding, the carton nailing side is attached to the guide strip 303, and is pushed to the lower side of the synchronous belt 4032, and the synchronous belt 4032 rotates to push the carton forward. When the carton reaches the lower side of the nailing device 2, the nailing device 2 performs nailing operation.
