Description

Technical Field

[0001] The utility model relates to the technical field of cardboard cutting, in particular to a cardboard cutting device at a discharge port of a single-facer machine. Background Art

[0002] The single-facer is a mechanical device for producing corrugated board (a special name for wavy paper in cardboard). In the corrugated packaging industry, it is known as the heart of the "corrugated board production line". The single-facer consists of a paper roll support and a single-face corrugated forming machine. First, the corrugated core paper is heated, then it is made into the required flute shape by corrugating rollers, and finally, the flute peaks are coated with glue and bonded with the corrugated surface paper to form a single-faced corrugated board. In order to meet the packaging requirements of different products, the cardboard needs to be cut into the required specific length and width, so cutting equipment is needed.

[0003] When the existing cutting equipment cuts the cardboard at the discharge port of the single-facer machine, the cardboard is usually transferred to the bottom of the cutting equipment through a transmission device for cutting. In the process of discharging at the discharge port of the single-facer machine, if the tension on the cardboard is inconsistent during the discharging process, some areas are too tight and some areas are loose, wrinkles are easily generated. At the same time, the material of the cardboard itself is uneven, the stiffness is insufficient or there are local defects, which are prone to wrinkles during discharging. The existence of wrinkles can easily lead to inaccurate cutting dimensions and deviations. During the transportation of the cardboard, certain impurities will adhere to the surface of the cardboard due to static electricity. The presence of impurities will frequently contact the tool during the cutting process, accelerate the wear of the tool, and reduce the service life of the tool. To address this problem, we proposed a cardboard cutting device for the discharge port of a single-facer machine. Utility Model Content

The fixed block 81 is fixedly installed on the surface of the fixed frame 7. A winding member 88 for winding the rubber rope 86 is arranged inside the fixed frame 7. The sliding rod 884 slides into the support frame 80 under the support of the second spring 886. The teeth 885 fixed on the surface of the sliding rod 884 slide on the surface of the first gear 883. The first gear 883 drives the rotating rod 882 to rotate under force. The wire reel 87 fixed on the surface of the rotating rod 882 winds the rubber rope 86 under force. The slider 84 fixed on the surface of the rubber rope 86 moves under the support of the first spring 85. Then the roller 82 can rotate inside the support rod 83 and smooth the cardboard placed on the surface of the conveying device 2, avoiding wrinkles that affect subsequent cutting.

[0026] The rewinding member 88 includes: a support plate 881, which is fixedly installed on the inner wall of the support frame 80. The support plate 881 is rotatably connected to the wire reel 87. When the wire reel 87 is stressed, it can rotate on the surface of the support plate 881. A rotating rod 882 is fixedly installed on the surface of the wire reel 87. The rotating rod 882 is rotatably connected to the inner wall of the support frame 80. The rotating rod 882 penetrates through the first gear 883 and is fixedly connected to the first gear 883. When the first gear 883 rotates, the rotating rod 882 can drive the wire reel 87 to rotate synchronously. The first gear 883 meshes with the engaging teeth 885. The engaging teeth 885 are fixedly installed on the surface of the sliding rod 884. The sliding rod 884 penetrates through the support frame 80 and is slidably connected to the support frame 80. The surface of the support frame 80 is fixedly connected to one end of the second spring 886. The other end of the second spring 886 is fixedly installed on the surface of the sliding rod 884.

The surface of the moving block 888 is fixedly connected to the surface of the hydraulic rod 889. The hydraulic rod 889 is arranged on the inner wall of the fixed frame 7. The hydraulic rod 889 can drive the moving block 888 to move longitudinally in the fixed frame 7. The driven assembly 9 includes: a rack 91, which is fixedly installed on the surface of the moving block 888. The rack 91 meshes with the second gear 92. The second gear 92 is rotatably connected to the surface of the flat plate 93. The flat plate 93 is fixedly installed on the inner wall of the fixed frame 7. When the moving block 888 moves, the rack 91 can slide on the surface of the second gear 92. A round rod 94 is fixedly installed on the surface of the second gear 92. The round rod 94 penetrates through the flat plate 93 and is rotatably connected to the flat plate 93. A disc 95 is fixedly installed on the surface of the round rod 94.

[0027] In the present utility model, during use, the single-sided machine 6 moves the cardboard out of the discharge port, and the cardboard after being moved out moves onto the surface of the conveying device 2. During the conveying process, the driving hydraulic rod 889 drives the moving block 888 to move downward. The support block 887 fixed on the surface of the moving block 888 drives the support frame 80 to move downward. When the moving block 888 moves downward, the rack 91 fixed on the surface of the moving block 888 slides on the surface of the second gear 92. The second gear 92 is stressed to drive the round rod 94 to rotate within the flat plate 93. The disc 95 and the fan blade 96 fixed on the surface of the round rod 94 rotate synchronously. The rotating disc 95 and fan blade 96 can generate wind power to blow away impurities and dust adhered to the surface of the cardboard, avoiding the influence of dust on the use of the tool. When the fixed block 81 fixed on the surface of the fixed frame 7 touches the cross-section of the sliding rod 884, the sliding rod 884 is stressed and slides into the support frame 80 under the support of the second spring 886. The engaging teeth 885 fixed on the surface of the sliding rod 884 slide on the surface of the first gear 883. The first gear 883 is stressed to drive the rotating rod 882 to rotate. The winding disc 87 fixed on the surface of the rotating rod 882 is stressed to wind up the rubber rope 86. The slider 84 fixed on the surface of the rubber rope 86 moves under the support of the first spring 85. Then, the roller 82 can rotate within the inner wall of the support rod 83 and smooth the cardboard placed on the surface of the conveying device 2, avoiding the influence of wrinkles on subsequent cutting. After smoothing, the driving hydraulic rod 889 drives the moving block 888 to move upward, then the sliding rod 884 is no longer touched, and the sliding rod 884 bounces under the support of the second spring 886. Then, the slider 84 will move to the right side of the support frame 80 for subsequent use. The smoothed cardboard is transported along with the conveying device 2. After being transported to the bottom of the cutting knife 5, the driving electric push rod 4 drives the cutting knife 5 to move downward to cut the cardboard.

[0028] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
