[0002] Generally, in the production process of environmentally friendly cartons, a variety of equipment is needed, including carton printing machines, corrugated production lines, laminating machines, line-touching machines, paper separators, slotting machines, paper mounting machines, die-cutting machines, laser engraving machines, carton proofing machines, beer machines, gluers and nailers. Among them, the die-cutting machine is a machine used for die-cutting cardboard in the carton forming process, which is generally divided into two types of die-cutting: flat-pressing and round-pressing.

[0003] At present, during the paper feeding process of the flatbed die-cutting machine, the carton sheets are placed on the transmission belt inside it by relying on friction, which has poor stability and causes unstable paper feeding. The transported carton sheets may be offset and unstable due to external forces such as vibration generated by the machine itself. The offset carton sheets will cause inaccurate positioning and insufficient die-cutting accuracy. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that the carton sheets transported by the flatbed die-cutting machine are placed on the transmission belt therein by relying on friction, which has poor stability and leads to unstable paper feeding, and to propose a production device for environmentally friendly cartons.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions:

[0007] A paper stabilizing suction mechanism is installed on the frame, and the paper stabilizing suction mechanism includes a plurality of suction nozzles. The top ends of the suction nozzles are arranged in the strip-shaped gap and are fixedly connected to the frame. The top ends of the air inlets in the suction nozzles are lower than the upper surfaces of the transmission belt 1 and the transmission belt 2.

[0008] Preferably, the paper stabilizing suction mechanism also includes a vacuum pump and an explosion-proof box. The explosion-proof box is fixedly connected to the frame. The vacuum pump is connected to the explosion-proof box through a high-pressure hose. The air outlets in several of the suction nozzles are fixedly connected to the explosion-proof box.

[0009] Preferably, a plurality of annular positioning grooves 2 and 1 are coaxially arranged on the periphery of the rotating roller, the transmission belt 1 is arranged in the annular positioning groove 2, and the transmission belt 2 is arranged in the annular positioning groove 1.

[0012] Preferably, a high-pressure bottle is fixedly connected below the suction nozzle, and the downwardly inclined surface of the micro air filter is arranged directly above the high-pressure bottle.

[0013] Compared with the prior art, the present invention provides a production device for environmentally friendly cartons, which has the following beneficial effects:

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0022] Refer to the attached Figure 1-4 A production device for environmentally friendly cartons includes a frame 1, which is a fixed bracket for installing a traditional transmission belt in a flatbed die-cutting machine in the prior art. Four rollers 3 are rotatably mounted on the frame 1 and are parallel to each other. The four rollers 3 are arranged on the same vertical plane. Two rollers 3 are respectively arranged on both sides of the top of the frame 1, and the remaining two rollers 3 are arranged at the lower end of the frame 1, and these two rollers 3 are arranged below the two rollers 3 on both sides of the top of the frame 1.

[0023] In this embodiment, the outer rings of the four rollers 3 are coaxially provided with an annular positioning groove 1 8 and two annular positioning grooves 2 9, and the two annular positioning grooves 2 9 are symmetrically arranged on both sides of the annular positioning groove 1 8. The outer rings of the four annular positioning grooves 2 9 in the same vertical plane are extruded and embedded with a transmission belt 1 4, that is, the transmission belt 1 4 is installed around the periphery of the four rollers 3, and the outer rings of the annular positioning grooves 8 in the four rollers 3 are embedded and wrapped with a transmission belt 2 5, that is, the two transmission belts 1 4 are symmetrically arranged on both sides of the transmission belt 2 5, and a strip gap 6 is reserved between the transmission belt 1 4 and the transmission belt 2 5.

[0024] In this embodiment, a motor 2 is fixedly installed on one side of the frame 1, and the output shaft of the motor 2 is coaxially fixedly connected to a roller 3 through a coupling, that is, when the motor 2 is energized and connected to an external power supply through a power cord, the output shaft of the motor 2 can drive the connected roller 3 to rotate synchronously, and the rotating roller 3 drives the two outer ring transmission belts 1 4 and transmission belt 2 5 to rotate synchronously, which is used to convey the carton sheet above the two transmission belts 1 4 and transmission belt 2 5. The width of the carton sheet is greater than that of the transmission belt 2 5, that is, the lower surface of the transmission belt 2 5 is arranged above the two strip slits 6.

[0025] In this embodiment, a paper stabilizing suction mechanism 7 is fixedly mounted on the frame 1. The paper stabilizing suction mechanism 7 includes a vacuum pump 71, a plurality of suction nozzles 73, and an explosion-proof box 74. The vacuum pump 71 is fixedly mounted on the frame 1. The suction port of the vacuum pump 71 is connected to a vacuum chamber 76 in the explosion-proof box 74 via a high-pressure hose 72. When the vacuum pump 71 is electrically connected to an external power source via a wire, the suction port of the vacuum pump 71 can generate suction, and the high-pressure hose 72 draws air from the vacuum chamber 76 in the explosion-proof box 74, creating a negative pressure state in the vacuum chamber 76.

[0026] Several suction nozzles 73 are evenly divided into two groups, which are arranged in a straight line and equidistantly and fixedly connected to both sides of the explosion-proof box 74, and the air outlet 77 in the suction nozzle 73 and the vacuum chamber 76 in the explosion-proof box 74 are connected to each other. The air inlet 79 in the suction nozzle 73 is set in the strip slit 6. Figure 4 The top of the air inlet 79 is lower than the upper surface of the transmission belt 1 4 and the transmission belt 2 5, that is, the air inlet 79 of the suction nozzle 73 does not contact the carton sheets transported on the transmission belt 2 5. The lower end of the suction nozzle 73 is threadedly connected to the high-pressure bottle 75. Figure 4 A miniature air filter element 78 is installed obliquely in the air outlet 77. The miniature air filter element 78 is mainly used to filter dust and debris in the air. The surface of the miniature air filter element 78 facing downward is located directly above the high-pressure bottle 75.

[0027] It should be noted that the vacuum chamber 76 in a negative pressure state transmits suction through the plurality of suction nozzles 73, that is, the air inlet 79 of the suction nozzle 73 has suction, which can suck the carton sheets transported above the two conveyor belts 1 4 and 2 5 downwards. Moreover, because the air inlet 79 of the suction nozzle 73 does not contact the carton sheets transported on the conveyor belt 2 5, the suction force generated by the air inlet 79 of the suction nozzle 73 can only suck the carton sheets downwards to press against the conveyor belt 1 4 and the conveyor belt 2 5, so that the carton sheets are more stably attached to the conveyor belt 1 4 and the conveyor belt 2 5, the paper feeding is more stable, and the transportation of the carton sheets will not be affected by stagnation.

[0028] The tiny particles of paper scraps, dust and other debris generated above the two strip-shaped slits 6 will also be sucked into the suction nozzle 73 that generates suction. After the debris enters the suction nozzle 73 from the air inlet 79 downward, it will be affected by the suction force and its own gravity, and approach the micro air filter 78 in the air outlet 77 or fall into the high-pressure bottle 75. The micro air filter 78 can block and filter paper scraps, dust and other debris in the air. The micro air filter 78 is set at an angle, that is, the debris close to the inclined lower surface of the micro air filter 78 needs to overcome the influence of its own gravity before it can contact the micro air filter 78 downward, thereby reducing the amount of debris filtered by the micro air filter 78, reducing the possibility of the micro air filter 78 being blocked by debris, and extending its service life. At the same time, the paper stabilizing suction mechanism 7 not only stabilizes the carton sheets, but also has the function of reducing dust and gathering tiny particles of paper scraps, dust and other debris.

[0029] The utility model firstly reserves two strip slits 6 between the two conveyor belts 1 4 and 2 5 for transporting carton sheets, and the strip slits 6 are arranged below the transport carton sheets. Secondly, while using the two conveyor belts 1 4 and 2 5 to transport carton sheets, the circuit in the vacuum pump 71 is connected, the suction port of the vacuum pump 71 can generate suction, and the air in the vacuum chamber 76 in the explosion-proof box 74 is extracted by the high-pressure hose 72, forming a negative pressure state in the vacuum chamber 76, and then the negative pressure suction is transmitted by the vacuum chamber 76 in the negative pressure state and the plurality of suction nozzles 73 arranged in the strip slits 6. , it attracts the carton sheets transported on the two conveyor belts 1 4 and 2 5 downwards, and because the air inlet 79 of the suction nozzle 73 does not contact the carton sheets transported on the conveyor belt 2 5, the suction force generated by the air inlet 79 of the suction nozzle 73 can only attract the carton sheets downwards to squeeze the conveyor belts 1 4 and 2 5, and make the carton sheets more stably adhere to the conveyor belts 1 4 and 2 5, so that the paper feeding of the carton sheets is more stable, the paper feeding process is smoother, the die-cutting is more accurate, and the position displacement of the carton sheets due to external forces such as vibration generated by the operation of the machine can be effectively avoided.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
