[0002] After the paper towels are produced, they are often rolled into paper rolls for easy transportation and use.

[0003] In order to improve the appearance of paper rolls after processing, they often need to be printed. Since the paper rolls need to be unwound during printing, they need to be moved to the unwinding area of ​​the printing equipment. The existing moving method is that workers pass the rotating shaft through the paper rolls and then manually lift them onto the rack. The process of manually lifting the paper rolls wastes the workers' time and energy. Utility Model Content

[0004] The utility model provides a paper roll feeding device, which is used to solve the defects in the prior art.

[0005] The utility model is realized through the following technical solutions:

[0006] A paper roll feeding device comprises a frame and a rotating shaft for inserting the paper roll, wherein the lower side of the feeding end of the frame is rotatably connected to a longitudinal rotating rod, and the rotating rod is driven to rotate along its axis by a rotating driving device; two parallel supporting rods are also vertically connected to the rotating rod, and a clamping rod is vertically connected to the front side of the supporting rod upward, and a supporting plate is arranged on the frame, and a clamping groove is arranged on the supporting plate on the same longitudinal line, and the distance from the clamping rod to the rotating rod along the supporting rod is not less than the height between the supporting plate and the rotating rod.

The rotary drive device drives the rotating rod to rotate counterclockwise along its axis, and then drives the support rod cigarette rotating rod to rotate counterclockwise. Driven by the support rod and the clamping rod, the paper roll moves upward. Since the distance from the clamping rod to the rotating rod is not less than the height between the support plate and the rotating rod, the position of the clamping rod can be moved to a position not lower than the support plate, so that the paper roll can be moved to the V-groove of the support plate, thereby saving the time and physical effort consumed by the staff to manually move the paper roll and ensuring the normal unwinding of the paper roll.

[0008] Preferably, the rotation drive device comprises an electric telescopic rod hingedly connected to the frame, the movable end of the electric telescopic rod is hingedly connected to a pull rod, and the pull rod is vertically fixedly connected to the rotating rod.

The rotating handle is rotated, and the rotation of the rotating handle drives the round rod to rotate along its axis, thereby driving the rotation of the screw, and since the screw is threadedly engaged with the thread hole on the slider, the slider slides longitudinally under the cooperation of the slide cabinet, therefore, the rotation of the screw drives the slider to move forward and backward, and the screw driving the slider can make the slider move more smoothly and the moving distance more accurate.

[0012] Preferably, when the electric telescopic rod is extended to the longest position, the outer end of the support rod is tilted upward, so as to ensure that the rotating shaft can be clamped when it is placed between the support rod and the clamping rod.

[0013] Preferably, the slot is a V-shaped structure that is wide at the top and narrow at the bottom, the pull rod is vertically connected to the support rod, and the side of the slot facing the shaft is inclined away from the shaft. The slot is a V-shaped structure that can adapt to shafts of different widths, the side of the slot facing the shaft is inclined away from the shaft, and the shaft can be easily lowered from the slot, and the pull rod is vertically connected to one side of the support rod, so that the support rod can be pulled better.

[0015] The beneficial effect of the utility model is as follows: when the present application is used, the extension and contraction of the electric telescopic rod can drive the rotating rod to rotate, thereby driving the flipping of the supporting rod through the rotation of the rotating rod, so as to flip the paper roll to the supporting plate, and then move the paper roll horizontally into the V-shaped groove to realize the movement of the paper roll, saving the time and physical strength consumed by the staff to manually lift the paper roll.

[0023] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] A paper roll feeding device, such as Figure 1-4As shown. It includes a frame 1 and a rotating shaft 16 for inserting a paper roll. A base is provided at the lower side of the feeding end of the frame 1. A longitudinal rotating rod 2 is rotatably connected between the front and rear bases through a bearing. The specific connection method is that a circular hole is opened on the base, the outer ring of the bearing is fixedly arranged in the circular hole, and the rotating shaft 16 penetrates the inner ring of the bearing and is fixedly connected to the inner ring of the bearing. The rotating rod 2 is driven to rotate along its axis by a rotating driving device. The rotating driving device includes an electric telescopic rod 7 hingedly connected to the frame 1, and a pull rod 8 is hingedly connected to the movable end of the electric telescopic rod 7.

[0025] Two parallel support rods 3 are also vertically connected to the rotating rod 2, and the pull rod 8 is vertically connected to any support rod 3. The front side of the support rod 3 is vertically connected to the clamping rod 4, and a support plate 5 is provided on the frame 1. The support plate 5 is provided with a clamping groove 6 located on the same longitudinal line. The distance from the clamping rod 4 to the rotating rod 2 along the support rod 3 is not less than the height from the support plate 5 to the rotating rod 2. When the electric telescopic rod 7 is extended to the longest, the outer end of the support rod 3 is tilted upward. When the electric telescopic rod 7 is retracted to the shortest, the support rod 3 is perpendicular to the ground.

[0026] When the present application is in use, the rotating shaft 16 is inserted into the paper roll, and then the rotating shaft 16 is clamped between the clamping rod 4 and the support rod 3, and then the rotating drive device is started. The shortening of the electric telescopic rod 7 can drive the clamping rod 4 to move toward the direction of the electric telescopic rod 7, and then the pull rod 8 drives the rotating rod 2 to rotate counterclockwise along its axis, and then drives the support rod 3 and the cigarette rotating rod 2 to rotate counterclockwise. Driven by the support rod 3 and the clamping rod 4, the paper roll moves upward, and when the electric telescopic rod 7 is retracted to the shortest, the support rod 3 is perpendicular to the ground. Since the distance from the clamping rod 4 to the rotating rod 2 is not less than the height between the support plate 5 and the rotating rod 2, the position of the clamping rod 4 can be moved to a position not lower than the support plate 5, so the paper roll can be moved to the V-groove of the support plate 5, thereby saving the time and physical strength consumed by the staff to manually move the paper roll and ensuring the normal unwinding of the paper roll.

[0027] It also includes two annular sleeves 9, which are fixedly sleeved on the rotating shaft 16, and the distance between the two annular sleeves 9 is consistent with the thickness of the support plate 5. The two annular sleeves 9 are sleeved on the rotating shaft 16 to achieve the positioning of the support plate 5 on the corresponding side, thereby preventing the rotating shaft 16 from sliding back and forth on the support plate 5 during unwinding.

[0028] Two longitudinal slide rails 10 are fixedly connected to the top surface of the frame 1, and a slider 11 is matched between the slide rails 10. The slider 11 is driven by a pushing device to move and stop along the slide rail 10. A support block 12 is fixedly connected downward to the top surface of the slider 11. The front and rear heights of the two support plates 5 are inconsistent, and the rear height is greater than the front height. The top surfaces of the two support plates 5 are located on the same transverse plane. The front support plate 5 is fixedly set on the support block 12 and the rear support plate 5 is fixedly set on the other side of the frame 1. The movement and stop of the slider 11 driven by the pushing device can drive the support block 12 to move and stop, and then drive the corresponding support plate 5 to move and stop. Since the annular sleeve 9 is stuck on both sides of the support plate 5, it can drive the rotating shaft 16 to move, so as to adjust the unwinding position.

[0029] The pushing device includes a screw and a round rod coaxially connected to the front end of the screw, a rotating handle 13 is fixedly connected to the front end of the round rod, a fixed plate 14 is fixedly connected to the end face of the slide rail 10, a through hole is provided on the fixed plate 14, the round rod passes through the through hole and is rotatably connected to the through hole through a bearing, a thread hole is provided on the slider 11, the screw passes through the thread hole and is threadedly engaged with the thread hole. The rotating handle 13 is rotated, and the rotation of the rotating handle 13 drives the round rod to rotate along its axis, thereby driving the rotation of the screw, and since the screw is threadedly engaged with the thread hole on the slider 11, the slider 11 slides longitudinally under the cooperation of the slide cabinet, therefore, the rotation of the screw drives the slider 11 to move forward and backward, and the screw driving the slider 11 can make the slider 11 move more smoothly and the moving distance more accurately.

[0030] The slot 6 is a V-shaped structure that is wide at the top and narrow at the bottom. The pull rod 8 is vertically connected to the support rod 3. The side of the clamp rod 4 facing the rotating shaft 16 is inclined to the side away from the rotating shaft 16. The slot 6 is a V-shaped structure that can adapt to the rotating shaft 16 of different widths. The side of the clamp rod 4 facing the rotating shaft 16 is inclined to the side away from the rotating shaft 16, which can facilitate the lowering of the rotating shaft 16 from the clamp rod 4. The pull rod 8 is vertically connected to one side of the support rod 3, which can better pull the support rod 3. Among them, the slide rail 10 is L-shaped and the two slide cabinets are symmetrically distributed along the screw rod. The slider 11 is located at the upper part of the two slide rails 10 and the bottom surface of the slider 11 extends downward with a protrusion 15 that penetrates the lower part of the slide rail 10. The screw hole is located on the protrusion 15. The bottom surface of the support block 12 contacts the top surface of the slide rail 10, thereby preventing the slider 11 from rotating in the slide rail 10 and ensuring that the slider 11 moves along the slide rail 10.

[0031] The use of the present application can drive the rotating rod 2 to rotate by extending and shortening the electric telescopic rod 7, thereby driving the support rod 3 to flip through the rotation of the rotating rod 2, so as to flip the paper roll to the support plate 5, and then move the paper roll horizontally into the V-shaped groove to realize the movement of the paper roll, saving the time and physical strength consumed by the staff to manually lift the paper roll.
