Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and in particular to a printing machine for producing carton boxes. Background Art

[0002] A carton printing machine is a printing device that can print the required text, patterns and other information onto the surface of a carton. It generally includes process flows such as plate mounting, inking, embossing, and paper feeding.

[0003] The working principle of a carton printing press is to first make the text and images to be printed into a printing plate, install it on a printing press, and then apply ink to the areas with text and images on the printing plate manually or by a printing press, and then transfer them directly or indirectly to paper or other printing materials (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby reproducing a printed product identical to the printing plate.

[0004] The output end of the existing carton printing machine lacks the organization and collection of carton boxes. After the carton printing is completed, they usually fall directly to the ground or into the collection box arranged in advance, causing multiple carton boxes to be stacked together in a messy manner, which is inconvenient to collect and wastes manpower. Therefore, improvements are needed to solve the above problems. Utility Model Content

[0040] like Figures 1-4 As shown, a printing machine for producing cartons is proposed, comprising a machine body 1; a circulating conveyor belt 2 is arranged on the machine body 1 and has a discharge end 3; a support plate 4 is fixedly or swingably arranged at the discharge end 3, and when the support plate 4 is fixedly arranged at the discharge end 3, the support plate 4 and the discharge end 3 are upward at an angle of 20°~30°; a centering mechanism 5 is arranged on the support plate 4 and is used to align the cartons laterally; a swinging member 6 is swingably arranged on the machine body 1 and is located on one side of the centering mechanism 5, and a baffle 7 is arranged on the support plate 4 and is located on the other side of the centering mechanism 5, and the swinging member 6 is used to push the carton box to abut against the baffle 7 after swinging, so that the carton box is longitudinally aligned.

[0041] In this embodiment, in order to solve the problem of lack of organization and collection of cartons at the output end of the carton printing machine in the related art, a pallet 4 is arranged at the discharge end 3 of the circulating conveyor belt 2. The pallet 4 can be fixed or swing-set. After the printing of the cartons is completed, the cartons will be sent to the pallet 4 by the circulating conveyor belt 2. Multiple cartons will be stacked together. After a batch of processing is completed, the centering mechanism 5 and the swinging member 6 are started to align the stacked cartons horizontally and vertically for organization. They will not fall directly to the ground and scatter, and there is no need to collect and organize them manually. They can be directly moved away, saving manpower and improving efficiency.

[0042] The machine body 1 firmly supports the entire device. The endless conveyor belt 2 is installed on the machine body 1. When it conveys the printed cartons to the discharge end 3, the tray 4 fixed at the discharge end 3 and facing upward at a 25° angle to the discharge end 3 receives the cartons.

[0043] The centering mechanism 5 is provided on the supporting plate 4, and two swing members 6 are symmetrically arranged on both sides of the circulating conveying belt 2. When the swing members 6 swing, they push the carton box to abut against the baffle 7 on the other side of the centering mechanism 5, so as to align the carton box in the longitudinal direction.

[0044] Further, the supporting plate 4 is provided with a through slot 8, the centering mechanism 5 comprises two push plates 9 which are arranged in the through slot 8 and move back and forth, and the moving directions of the two push plates 9 are opposite. Further, the push plate 9 is provided with a through hole 10 and a through hole 11, the centering mechanism 5 further comprises a lead screw 12 which is rotatably arranged on the machine body 1 through the through hole 10, and a guide column 13 which is arranged on the machine body 1 through the through hole 11 and is located on one side of the lead screw 12.

[0045] In the embodiment, the two push plates 9 which are independent and move in opposite directions are arranged in the through slot 8, and the push plates 9 are driven by the lead screw 12 to move back and forth in the through slot 8. The lead screw 12 can be provided with two threads which rotate in opposite directions, or the lead screw 12 is composed of two lead screws 12 which rotate in opposite directions, so as to realize the moving of the two push plates 9 to approach or move away from each other. The two push plates 9 in the through slot 8 move back and forth in opposite directions under the driving of the lead screw 12 and the guiding of the guide column 13, for example, one push plate 9 moves to the right, and the other push plate 9 moves to the left, so as to align the carton box in the transverse direction.

[0046] Further, when the supporting plate 4 is swingably arranged at the discharging end 3, the baffle 7 is swingably arranged on the supporting plate 4, further comprising a fixing frame 14 which is arranged on the machine body 1 and is located on one side of the swing member 6, and a tension spring 15 which is arranged on the fixing frame 14 at one end and is arranged on the baffle 7 at the other end.

[0047] In the embodiment, the supporting plate 4 can also be swingably arranged. In the initial state, the inclination angle of the supporting plate 4 is the same as that when the supporting plate 4 is fixedly arranged. After a batch of carton boxes are processed, the centering mechanism 5 and the swing member 6 align the carton boxes, and then the supporting plate 4 swings downward. Under the action of the tension spring 15, the baffle 7 is gradually pulled away, and finally the carton box slides off the supporting plate 4. A collecting box can be arranged below the supporting plate 4 to collect the aligned carton boxes.

[0048] Further, the limiting column 16 is arranged on the fixing frame 14, one end of the tension spring 15 is arranged on the limiting column 16, and the limiting column 16 is provided with a stopper 17.

[0049] In the embodiment, when the swing type supporting plate 4 is designed, the baffle 7 is also designed as a swing structure, is connected with the fixing frame 14 on one side and is adjusted by the tension spring 15. One end of the tension spring 15 is connected with the limiting column 16 on the fixing frame 14, the limiting column 16 is provided with the stopper 17 to fix the position of the tension spring 15, so as to ensure that the rebound force of the baffle 7 is just right.

[0050] Furthermore, there are two baffles 7 , and a gap 18 is left between the two baffles 7 .

[0051] In this embodiment, in order to accommodate cartons of different sizes, the baffles 7 are designed to be symmetrically distributed. Alternatively, the pallet 4 can be swung to a horizontal angle so that a forklift can be inserted through the gap 18. A slope can be provided on the pallet 4 at the gap 18 to facilitate forklift insertion without damaging the cartons.

[0052] Furthermore, the screw rod 12 and the guide post 13 are located below the support plate 4. Furthermore, there are two swing members 6, which are symmetrically distributed on both sides of the endless conveyor belt 2.

[0053] In this embodiment, considering efficiency and balance, the swing members 6 are provided as a pair, which are symmetrically installed on both sides of the circulating conveyor belt 2 and can work synchronously to improve the longitudinal alignment efficiency of the cartons.

[0054] Furthermore, the two baffles 7 are symmetrically distributed on the supporting plate 4. Furthermore, there are two tension springs 15, which are respectively arranged on the two baffles 7.

[0055] In this embodiment, a double baffle 7 is designed, and each baffle 7 is equipped with a separate tension spring 15 to ensure that each carton box can obtain a uniform and stable centering thrust even in a high-speed production process.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
