Technical Field

[0001] The utility model relates to the technical field of carton processing equipment, in particular to a nailing machine used for producing cartons. Background Art

[0002] Nowadays, cartons are the most widely used packaging products. They are divided into corrugated cartons and single-layer cardboard cartons according to different materials. With the continuous development of packaging technology, the requirements for the appearance of corrugated cartons are becoming higher and higher. In the carton production process, nailing and edge sealing is the last production process of the carton forming, and the carton needs to be fixed in position during the nailing process.

[0003] A nailing machine currently used for producing cartons was found through search in the utility model with patent publication number CN213108428U. The nailing machine includes a base, a support column is provided on the upper outer surface of the base, a force plate is provided on the upper outer surface of the support column, a nailing force panel is provided on the upper outer surface of the force plate, a nailing groove is provided on the upper outer surface of the nailing force panel, and a rotatable spring clip is provided on the upper end of the nailing groove. The rotatable spring clip facilitates the fixation of one end of the paper box.

[0004] Although the above patent solves the problems in the above-mentioned background technology, it still has the following shortcomings: the nailing machine relies on a rotating spring clamp to fix the position of the carton. The clamping force of the rotating spring clamp cannot be accurately controlled.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0026] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0027] A nailing machine for producing cartons includes a workbench 1, with a mounting slot 2, a mounting frame 3, and a positioning clamping mechanism 4 provided on the top of the workbench 1. A roller 201 is provided within the mounting slot 2. The mounting frames 3 are located at the left and right ends of the workbench 1. A connecting plate 301 is fixedly mounted between the mounting frames 3. A synchronous cylinder 302 is provided on the top of the connecting plate 301. A nailing mechanism 5 for nailing cartons is provided on the bottom of the connecting plate 301.

[0028] Specifically, there are multiple rollers 201, and the front and rear ends of the multiple rollers 201 are rotatably connected to the inner wall of the installation groove 2 through bearings. The multiple rollers 201 are evenly distributed on the left and right sides of the inner wall of the installation groove 2, and their outer top ends are flush with the top surface of the workbench 1;

[0029] In this embodiment, the roller 201 is provided to enable the cartons to move along the workbench 1 , providing convenience for the staff.

[0030] Specifically, the telescopic end of the synchronization cylinder 302 passes through the top surface of the connecting plate 301 and is fixed to the top surface of the nailing mechanism 5;

[0031] In this embodiment, the synchronous cylinder 302 is mainly used to drive the nailing mechanism 5 to move up and down, so as to facilitate the nailing mechanism 5 to contact with the carton and realize the nailing operation on the carton.

[0032] In this embodiment, please refer to Figure 1 、 Figure 2 and Figure 3 The positioning and clamping mechanism 4 includes a mounting plate 401 fixedly mounted on the top side of the workbench 1, a synchronous electric push rod 402 is fixedly mounted on the rear side of the mounting plate 401, a through hole 403 is provided on the rear surface of the mounting plate 401, and a movable plate 404 is provided on the front side thereof, and a supporting compression spring 405 and a limiting slide 406 are respectively provided on the front side of the movable plate 404, and a clamping plate 407 is fixedly mounted on the end of the supporting compression spring 405 and the limiting slide 406 away from the movable plate 404;

[0033] Specifically, the mounting plate 401 is arranged in a front-to-back mirror image with respect to the top central axis of the workbench 1. The telescopic end of the synchronous electric push rod 402 movably passes through the rear surface of the mounting plate 401 and is fixedly connected to the rear surface of the movable plate 404. The rear end of the limiting slide 406 fits through the front surface of the movable plate 404 and extends backward. The through hole 403 is arranged corresponding to the limiting slide 406, and its inner wall is in contact with the outer surface of the limiting slide 406. The facing side surfaces of the clamping plate 407 are all provided with rubber pads.

[0034] In this embodiment, the setting of the synchronous electric push rod 402 is mainly used to quickly drive the movable plate 404 and the clamping plate 407, so that the clamping plate 407 contacts the carton. Through the setting of the supporting compression spring 405 and the limiting slide 406, the supporting compression spring 405 elastically supports the clamping plate 407, and the limiting slide 406 slides along the inner wall of the movable plate 404, thereby ensuring the smooth movement of the clamping plate 407 and meeting the clamping requirements of the carton.

[0035] The working process of the utility model is as follows: when a nailing machine for producing cartons is used, the carton is moved along the workbench 1 under the action of the roller 201 until the carton moves to the bottom of the nailing mechanism 5, and then the carton is fixed in position, the synchronous electric push rod 402 is started, the telescopic end of the synchronous electric push rod 402 begins to extend and drives the moving plates 404 to move toward each other, and then the clamping plate 407 gradually approaches the outer surface of the carton as the moving plate 404 moves, and the moving plate 404 is pressed against the outer surface of the carton. During the contact between 404 and the carton, the supporting compression spring 405 begins to shrink, and at the same time, the limiting slide bar 406 slides in contact with the inner wall of the movable plate 404. The supporting compression spring 405 will generate an elastic force when shrinking. This elastic force makes the clamping plate 407 better in contact with the carton, thereby improving the clamping effect of the carton. Finally, the nailing mechanism 5 is driven by the synchronous cylinder 302, so that the nailing mechanism 5 contacts the carton and performs the nailing operation, thereby improving the practical effect of the nailing machine.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
