Description

Technical Field

[0001] The utility model relates to the technical field of carton creasing, in particular to a carton creasing wheel structure. Background Art

[0002] Before the paperboard becomes a carton, the two ends of the paperboard need to be connected together by a carton stapling machine first to facilitate the formation of the subsequent box body. Before stapling the carton, the paperboard needs to be creased to form crease marks, so that it will be very convenient during the subsequent folding process. In the prior art, for thicker corrugated paper, pre-creasing and creasing are adopted in two steps, and for thinner corrugated paper, one-time creasing is adopted, and mostly single-sided creasing is used, and a small number use double-sided creasing. Just like the new creasing wheel of the carton machine announced in the patent document CN208343562U, a new type of carton creasing wheel announced in CN214354468U, a creasing device for a semi-automatic carton stapling machine announced in CN216610264U, etc., corresponding equipment needs to be used for corrugated paper of different sizes. In short, there is a lack of a creasing structure that can adapt to multiple uses, multiple functions, and strong adaptability.

[0003] Now a carton creasing wheel structure is provided, which can meet the creasing requirements of cartons of various thicknesses, has a simple structure, and can meet the current carton creasing requirements. Summary of the Utility Model

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a carton creasing wheel structure, which effectively solves the problem that the creasing device in the prior art cannot meet the creasing requirements of cartons of different thicknesses and sizes and has a limited adaptation range.

[0005] The technical solution it adopts is that it includes a U-shaped frame. There are two horizontal square shafts in the frame. A plurality of positioning cylinders are buckled on the square shafts. The positioning cylinders on the two square shafts correspond to each other up and down. A long arm is fixed at both the front and rear ends of the positioning cylinder. A pressing wheel is fixed at the end of the long arm. The two long arms on the same positioning cylinder form a V-shaped structure, and the openings of the two V-shaped structures corresponding up and down are opposite; the square shafts can rotate, and the distance between the two square shafts can be increased or decreased.

[0006] Further, a housing corresponding to the square shaft is arranged on the side wall of the frame. There is a worm and worm gear mechanism in the housing. The end of the square shaft is coaxially fixed with a worm. The two worms on the same side are coaxially arranged. The worm is rotatably connected to the side wall of the housing; the inside of the worm is hollow, and a vertical spline shaft is inserted into the worm. The spline shaft can rotate actively. The spline shaft penetrates through the worm on the same side from top to bottom. The rotation of the spline shaft can drive the worms on the same side to rotate simultaneously, so as to realize the rotation of the square shaft.

[0007] Further, there is a double-headed lead screw between two casings on the same side. The middle part of the double-headed lead screw is installed on the frame through a small plate, and the small plate is rotatably connected to the double-headed lead screw. Threaded cylinders are screwed onto both ends of the double-headed lead screw, and the threaded cylinders are fixed to the corresponding casings. Rotating the double-headed lead screw can control the two casings on the same side to approach or move away from each other, thereby realizing the adjustment of the distance between the two square shafts.

[0008] Further, the positioning cylinder is composed of two parts, and the two parts are fixed together through a plurality of bolts.

[0009] Further, a motor is connected to the upper end of the spline shaft, and the motor is fixed on the frame.

[0010] The utility model has a clever structure and can meet the creasing requirements of cartons of various thicknesses. The structure is simple and can meet the current carton creasing requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following further elaborates the detailed embodiments of the utility model with reference to the accompanying drawings.

[0017] Given by Figures 1 to 5 The utility model includes a U-shaped frame 1. There are two horizontal square shafts 2 inside the frame 1. A plurality of positioning cylinders 3 are buckled on the square shafts 2. The positioning cylinders 3 on the two square shafts 2 correspond to each other up and down. A long arm 4 is fixed at both the front and rear ends of the positioning cylinder 3. A pressing wheel 5 is fixed at the end of the long arm 4. The two long arms 4 on the same positioning cylinder 3 form a V-shaped structure, and the openings of the two V-shaped structures corresponding up and down face each other; the square shafts 2 can rotate, and the distance between the two square shafts 2 can be increased or decreased.

[0018] To enable the square shaft 2 to rotate, a housing 6 corresponding to the square shaft 2 is provided on the side wall of the frame 1. There is a worm and worm gear mechanism inside the housing 6. The end of the square shaft 2 is coaxially fixed to the worm wheel 7. Two worms 8 on the same side are coaxially arranged, and the worms 8 are rotatably connected to the side wall of the housing 6. The inside of the worm 8 is hollow, and a vertical spline shaft 9 is inserted into the worm 8. The spline shaft 9 can rotate actively. The spline shaft 9 penetrates the worms 8 on the same side from top to bottom. The rotation of the spline shaft 9 can drive the worms 8 on the same side to rotate simultaneously, realizing the rotation of the square shaft 2.

[0019] To be able to adjust the distance between the two square shafts 2, a plurality of vertical grooves corresponding to the housing 6 one by one are provided on the side wall of the frame 1. A slider matched with the vertical groove is fixed on the housing 6. The slider can slide in the vertical groove. There is a double-headed lead screw 10 between the two housings 6 on the same side. The middle of the double-headed lead screw 10 is installed on the frame 1 through a small plate. The small plate is rotatably connected to the double-headed lead screw 10. Threaded barrels 11 are screwed on both ends of the double-headed lead screw 10. The threaded barrel 11 is fixed to the corresponding housing 6. Rotating the double-headed lead screw 10 can control the two housings 6 on the same side to approach or move away from each other, thereby realizing the adjustment of the distance between the two square shafts 2.

[0020] To facilitate the disassembly of the positioning cylinder 3 and thus be able to conveniently adjust the position of the positioning cylinder 3 on the square shaft 2, the positioning cylinder 3 is composed of two parts, and the two parts are fixed together through a plurality of bolts.

[0021] The upper end of the spline shaft 9 is connected to a motor 12, and the motor 12 is fixed on the frame 1.

[0022] It should be noted that bearings are installed between the double-headed lead screw 10 and the small plate, and bearings are installed between the worm 8 and the side wall of the housing 6; the spiral threads on the two worms 8 corresponding up and down have opposite helix directions. When the two worms 8 on the same spline shaft 9 rotate simultaneously, the corresponding two worm wheels 7 rotate in opposite directions.

[0023] During use, the cardboard is passed from front to back between the two square shafts 2, and then creasing of the cardboard is realized under the action of the upper and lower corresponding pressure wheels 5. When the cardboard is relatively thick, the motor 12 can be started. The rotation of the motor 12 drives the spline shaft 9 to rotate. The spline shaft 9 drives the worm 8 to rotate. The worm wheel 7 drives the square shaft 2 to rotate. The distance between the upper and lower corresponding pressure wheels 5 at the front side becomes larger, and the distance between the two upper and lower corresponding pressure wheels 5 at the rear side decreases. In this way, when the cardboard passes through, it is first pre-creased and then creased, completing the creasing process in two times; by rotating the double-headed lead screw 10, the device can be adapted to cardboard of different thicknesses. Specifically, by rotating the double-headed lead screw 10, the double-headed lead screw 10 drives the two housings 6 to approach or move away from each other through the threaded barrels 11 at both ends, thereby realizing the adjustment of the interval size between the square shafts 2 to meet cardboard of different thickness dimensions.

[0024] The structure of the utility model is ingenious, which can meet the creasing requirements of cartons with various thicknesses. The structure is simple and can meet the current creasing requirements of cartons.
