Detailed Implementation

[0024] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0025] The embodiments provided by this utility model are as follows: Figures 1-5 As shown, a batch flattening carton centering mechanism includes a frame 10, a bidirectional lead screw 20 horizontally arranged on the frame 10, a horizontal drive assembly 30 arranged on the frame 10, the horizontal drive assembly 30 being used to drive the bidirectional lead screw 20 to rotate around its own axis, a vertical centering pressure plate 40 mirrored along the center position on the bidirectional lead screw 20, the two being threadedly connected, a stacking plate 50 horizontally arranged on the frame 10, and a vertical drive assembly 60 arranged on the frame 10, the vertical drive assembly 60 being used to drive the stacking plate 50 to move in the vertical direction.

[0026] In operation, workers push batches of flattened cardboard boxes onto the stacking plate 50, activate the horizontal drive assembly 30, which drives the bidirectional lead screw 20 to rotate. This, in turn, moves the two centering pressure plates 40 on the bidirectional lead screw 20 simultaneously to the center position of the lead screw 20. Once one of the centering pressure plates 40 contacts the cardboard box, it drives the cardboard box to continue moving until both centering pressure plates 40 are in contact with the cardboard box, achieving centering of the cardboard box. The workers then control the horizontal drive assembly 30 to drive the bidirectional lead screw 20 to rotate in the opposite direction, resetting the two centering pressure plates 40. Afterward, the workers activate the vertical drive assembly 60, which drives the stacking plate 50 upward. The stacking plate 50 then moves the centered batch of flattened cardboard boxes to the next process flow area, achieving automated centering and transportation of the cardboard boxes.

[0027] It should be noted that the double-acting screw 20 is a threaded rod with opposite threads on the left and right sides, with the middle position as the boundary. Selecting this double-acting screw 20 can ensure that the centering pressure plates 40 on both sides converge towards the middle or separate towards both sides simultaneously.

[0028] Preferably, the horizontal drive assembly 30 includes a drive motor 31, which is fixedly mounted on the right side of the frame 10. The output end of the drive motor 31 is fixedly fitted with a drive wheel 32, and the right end of the bidirectional lead screw 20 is fixedly fitted with a driven wheel 33. The drive wheel 32 and the driven wheel 33 are connected by a conveyor belt 34.

[0029] Preferably, the vertical drive assembly 60 includes a geared motor 61 and a rotating shaft 62. The geared motor 61 is fixedly mounted on the right side of the frame 10. A first gear 63 is fixedly mounted on the output end of the geared motor 61. The rotating shaft 62 is horizontally mounted on the frame 10 and the two are rotatably connected. A second gear 64 is fixedly mounted on the right end of the rotating shaft 62. The first gear 63 and the second gear 64 are connected by a first transmission chain 65 that meshes with them. A third gear 66 is fixedly mounted on both ends of the rotating shaft 62. A second transmission chain 67 that meshes with the third gear 66 is wound around the third gear 66. One end of the second transmission chain 67 is fixedly connected to the stacking plate 50, and the other end hangs down naturally.

[0030] It should be noted that the second drive chain 67 is pre-installed on the third gear 66, and the naturally hanging part of the second drive chain 67 itself has a certain weight. When the stacking plate 50 is pulled, the stacking plate 50 rises slowly, and the third gear 66 will not spin freely or slip between the third gear 66 and the second drive chain 67.

[0031] Preferably, a fourth gear 70 is fixedly sleeved at both ends of the rotating shaft 62, and a support rod 80 is horizontally fixedly installed on the left and right inner walls of the frame 10. A fifth gear 90 is sleeved on the support rod 80 and the two are connected by bearings. A meshing third transmission chain 100 is wound around the fourth gear 70 and the fifth gear 90. One end of the third transmission chain 100 is fixedly connected to the stacking plate 50, and the other end hangs down naturally. By adding the third transmission chain 100, the stability of the vertical movement of the stacking plate 50 can be improved, and the swaying of the stacking plate 50 during movement can be avoided.

[0032] Preferably, a rotating shaft fixing component 110 is fixedly installed on the frame 10. The rotating shaft fixing component 110 is sleeved in the middle position of the rotating shaft 62 and the two are connected by bearings. The rotating shaft fixing component 110 can improve the stability of the rotating shaft 62 when it rotates and prevent the rotating shaft 62 from shaking when the gears and chains rotate, which would affect the vertical movement of the stacking plate 50.

[0033] Preferably, slide rods 120 are vertically fixed on the left and right inner walls of the frame 10, and sliders 130 are fixed on the left and right sides of the stacking plate 50. The sliders 130 are slidably connected to the slide rods 120. The slide rods 120 and the sliders 130 can improve the stability of the stacking plate 50 when it moves vertically and prevent the stacking plate 50 from shaking.

[0034] Preferably, a pulley 140 is fixedly sleeved on the slider 130, and the pulley 140 is tumbledly connected to the slide rod 120. The pulley 140 can reduce the friction between the slide rod 120 and the slider 130, making the vertical movement of the stacking plate 50 smoother.

[0035] Preferably, a guide rod 150 is horizontally arranged on the frame 10, and the centering pressure plate 40 is sleeved on the guide rod 150. The centering pressure plate 40 and the guide rod 150 are slidably connected. The guide rod 150 can improve the stability of the centering pressure plate 40 during movement and prevent the centering pressure plate 40 from shaking, which would affect the centering effect.

[0036] Preferably, a support rod 160 is horizontally fixed at the top of the frame 10. The support rod 160 can prevent the frame 10 from shaking when the centering mechanism is working, thereby improving the overall stability of the centering mechanism.

[0037] Preferably, support feet 170 are fixedly installed at the four corners of the bottom of the frame 10. By installing support feet 170, on the one hand, the bottom of the frame 10 can be prevented from directly contacting the ground and causing wear, and on the other hand, a gap is left between the frame 10 and the ground to facilitate the handling by the staff.

[0038] The working principle of this embodiment, and its more specific process, are as follows:

[0039] Workers push batches of flat cardboard boxes onto stacking board 50, start drive motor 31, drive motor 31 drives drive wheel 32 to rotate, drive wheel 32 drives driven wheel 33 to rotate via conveyor belt 34, driven wheel 33 drives double-acting screw 20 to rotate, which in turn drives two centering pressure plates 40 on double-acting screw 20 to move simultaneously to the center position of double-acting screw 20 along guide rod 150. When one centering pressure plate 40 contacts the cardboard box, it drives the cardboard box to continue moving until both centering pressure plates 40 are in contact with the cardboard box, achieving centering of the cardboard box. Workers then control drive motor 31 to drive drive wheel 32 to rotate in the opposite direction, thereby driving double-acting screw 20 to rotate in the opposite direction, resetting the two centering pressure plates 40. Then, workers start deceleration. Motor 61, a geared motor 61, drives the first gear 63 to rotate. The first gear 63 drives the second gear 64 to rotate via the first transmission chain 65. The second gear 64 drives the rotating shaft 62 to rotate. The rotating shaft 62 drives the third gear 66 and the fourth gear 70 to rotate. The third gear 66 drives the second transmission chain 67 to rotate. The fourth gear 70 drives the third transmission chain 100 to rotate. The second transmission chain 67 and the third transmission chain 100 together pull the stacking plate 50 upward. During the upward movement of the stacking plate 50, the slider 130 and the pulley 140 move along the slide bar 120 to ensure the smooth movement of the stacking plate 50. The stacking plate 50 drives the aligned batch of flattened carton boards to the next process flow area, realizing the automated alignment and transportation of the carton boards.

[0040] The batch flattening carton board centering mechanism of this utility model has a bidirectional lead screw 20 horizontally arranged on the frame 10, a horizontal drive assembly 30 arranged on the frame 10, a vertical centering pressure plate 40 mirrored along the center position on the bidirectional lead screw 20, and the two are threadedly connected. A stacking plate 50 is horizontally arranged on the frame 10, and a vertical drive assembly 60 is arranged on the frame 10. This enables the batch flattening carton board centering mechanism to realize the batch centering and transportation of flattened carton boards, thereby improving production efficiency.
