[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0017] Reference Figure 1 to Figure 3 . The paper roll conveying centering mechanism includes a moving frame 1, a lifting frame 2, a lifting device 3, a support seat 4, a front-to-back adjusting device 5 and a left-to-right adjusting device 6. The lifting device 3 is arranged in the moving frame 1, the lifting frame 2 is located above the moving frame 1 and is connected to the lifting device 3, the support seat 4 is arranged on the lifting frame 2, the left-to-right adjusting device 6 and the front-to-back adjusting device 5 are both arranged on the lifting frame 2, and the front-to-back adjusting device 5 is connected to the support seat 4. Among them, the left-to-right direction is the width direction of the paper roll, and the front-to-back direction is perpendicular to the left-to-right direction. The front-to-back adjusting device 5 can be used to center the front-to-back position of the paper roll, that is, the axis of the paper roll is centered; the left-to-right adjusting device 6 can be used to adjust the width direction of the paper roll so that the left-to-right position of the paper roll can be centered; the lifting device 3 can be used to center the height position of the paper roll.
[0018] The support seat 4 includes a first mounting seat 41 and a second mounting seat 42, each of which is provided with a support roller 43, and each of the first mounting seat 41 and the second mounting seat 42 is connected to the front and rear adjustment device 5. The support roller 43 may be a universal roller, which supports and protects the roll paper and facilitates the adjustment of the position of the roll paper in all directions.
[0019] The front and rear adjustment device 5 includes a first motor 51, a first gear 52, a first rack 53 and a second rack 54. The first motor 51 is fixed on the lifting frame 2, the first gear 52 is sleeved on the output shaft of the first motor 51, the first rack 53 is fixed to the first mounting seat 41, and the second rack 54 is fixed to the second mounting seat 42. The first rack 53 and the second rack 54 are arranged in parallel and are respectively meshed with the upper and lower ends of the first gear 52.
[0020] Since the first rack 53 and the second rack 54 are respectively meshed with the upper and lower ends of the first gear 52, when the first gear 52 rotates, the movement directions of the first rack 53 and the second rack 54 are opposite, thereby driving the first mounting seat 41 and the second mounting seat 42 to move outward or inward at the same time, thereby increasing or shortening the distance between the first mounting seat 41 and the second mounting seat 42.
[0021] The front-rear adjustment device 5 further includes a first slide rail 55. The bottoms of the first mounting seat 41 and the second mounting seat 42 are both provided with a slider 44. The slider 44 cooperates with the first slide rail 55. The first slide rail 55 is arranged parallel to the first rack 53. Through the cooperation between the slider and the first slide rail 55, the first mounting seat 41 and the second mounting seat 42 can be guided and the stability during movement can be improved.
[0022] The left-right adjustment device 6 includes a second motor 61, a conveyor belt 62 and a roller 63. The second motor 61 is arranged on the lifting frame 2. The conveyor belt 62 is located between the first mounting seat 41 and the second mounting seat 42. There are two rollers 63, one of which is connected to the output shaft of the second motor 61. The conveyor belt 62 is sleeved on the two rollers 63. The conveying direction of the conveyor belt 62 is perpendicular to the length direction of the first rack 53. In the actual installation process, a pulley is installed on the output shaft of the second motor 61, and a pulley is installed on the rotating shaft of one of the rollers. The two pulleys are connected by a transmission belt, so that the second motor 61 drives the roller 63 to rotate, thereby driving the conveyor belt 62 to transmit. By controlling the rotation direction of the second motor 61, the conveying direction of the conveyor belt 62 can be adjusted.
[0023] The lifting device 3 includes an electric cylinder 31, and the telescopic rod of the electric cylinder 31 is connected to the lifting frame 2. In order to improve the stability of the lifting frame 2, the paper roll conveying centering mechanism also includes a guide rod 8, which is a plurality of guide rods 8. The guide rods 8 penetrate the moving frame 1 and are connected to the lifting frame 2.
[0024] The specific working process of the paper roll conveying centering mechanism of the utility model is as follows:
[0025] When the paper roll is delivered to the mechanism, the telescopic rod of the electric cylinder 31 extends upward by a corresponding distance according to the thickness of the paper roll, pushing the lifting frame 2 to move upward, so as to facilitate the centering adjustment of the height direction of the paper roll; at the same time, the support rollers 43 on the first mounting seat 41 and the second mounting seat 42 are driven to support the paper roll upward, and the axis of the paper roll is centered through the support of the first mounting seat 41 and the second mounting seat 42. Subsequently, the first motor 51 is turned on, driving the first gear 52 to rotate, driving the first rack 53 and the second rack 54 to move outward, so that the distance between the first mounting seat 41 and the second mounting seat 42 gradually increases. At this time, the paper roll can gradually move downward until the bottom end of the paper roll falls on the conveyor belt 62, and the second motor 61 is turned on to drive the conveyor belt 62 to drive, thereby driving the paper roll on the conveyor belt 62 to achieve centering adjustment in the left and right directions (i.e., the width direction of the paper roll).
[0026] The roll paper conveying and centering mechanism also includes a driving device 7, which includes a third motor 71, a second gear 72 and a third rack 73. The third motor 71 is fixed in the mobile frame 1, and the third rack 73 is located below the mobile frame 1. The second gear 72 is connected to the output shaft of the third motor 71, and the second gear 72 cooperates with the third rack 73. Among them, the third rack 73 can be fixed on the frame of the roll paper packaging machine, so when the third motor 71 is started, it drives the second gear 72 to rotate, so that the second gear 72 moves relative to the third rack 73, so that the second gear 72 drives the third motor 71 and the entire mobile frame 1 to move along the third rack 73, so as to realize the conveyance of the roll paper and facilitate the roll paper to move to different stations for corresponding packaging processes.
[0027] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
