Description

Technical Field

[0001] The utility model relates to the technical field of paper box processing equipment, in particular to a turning device for paper box processing. Background Art

[0002] Paper boxes are usually used as packaging for goods or as outer protective layers for items. They can be divided into corrugated boxes, single-layer cardboard boxes, etc. according to different materials. They have been widely used in various fields. Nowadays, paper boxes are an indispensable part of modern logistics, shouldering the important responsibilities of containing, protecting products, and aesthetically pleasing. In the process of paper box processing, automated machines are needed to flip the paper boxes.

[0003] In the prior art, the Chinese utility model with publication number CN219312130U discloses a carton flipping device, which relates to the field of carton processing technology and includes a base, a conveyor belt is provided on the inner side of the base, and mounting plates are fixedly installed on the front ends of the left and right sides of the top of the base. The utility model controls the cylinder 1 to drive the telescopic rod 1 to extend and retract according to the size of the carton, driving the inner connecting plates to move closer to each other and adjusting the distance between the connecting plates on both sides to adapt to the current carton. By rotating the guide plate along the hinge with the guide plate, the guide plate can guide the carton to the center. The carton passes through the conveyor belt to the front of the carrier plate, and is pushed to the top of the carrier plate by the rear carton. The carton is straightened by the rotation of the guide roller in the connecting plate and the continuous push of the rear carton. At the same time, by controlling the cylinder 2 to drive the telescopic rod 2 to drive the barrier rod to contract, the carton is pushed onto the conveyor belt for continued transportation, thereby achieving the straightening and controlling the speed to prevent the carton from flipping over.

[0004] Although the above technical solution flips the paper box by adsorbing it through a negative pressure suction cup, when the negative pressure suction cup contacts the paper box, the paper box is in a moving state due to being transported by a conveyor belt, which causes the negative pressure suction cup to be unable to stably adsorb the paper box and causes the position of the paper box to shift again, thereby failing to flip the paper box. The stability of the paper box flipping needs to be further improved, so we need to propose a flipping device for paper box processing. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 The utility model provides a technical solution: a turning device for carton processing, comprising a protective frame 1, an inner cavity of the protective frame 1 is provided with a conveyor belt 7, one end of the upper surface of the protective frame 1 is fixedly connected to a bracket 2, and a limiting mechanism 6, a turning mechanism 4 and a controller 5 are installed on the bracket 2;

[0022] The limiting mechanism 6 includes a fixed plate 61, a first cylinder 62, a fixed baffle 63 and a movable plate 65. The first cylinder 62 is installed on the upper surface of the fixed plate 61. The telescopic end of the first cylinder 62 passes through the fixed plate 61 and is fixedly connected to the upper surface of the fixed baffle 63. A second cylinder 64 is installed on one side of the fixed baffle 63. The telescopic end of the second cylinder 64 is fixedly connected to one side of the movable plate 65. One side of the fixed baffle 63 is plugged with multiple groups of first limiting rods, and one end of the multiple groups of first limiting rods are fixedly connected to the limiting buffer plate 67. The outer sides of the multiple groups of first limiting rods are all sleeved with first buffer springs 68. One side of the movable plate 65 is plugged with multiple groups of second limiting rods, and one end of the multiple groups of second limiting rods are all fixedly connected to the movable buffer plate 69. The outer sides of the multiple groups of second limiting rods are all sleeved with second buffer springs 610.

[0023] Multiple groups of connecting rods 66 are fixedly connected to one side of the movable plate 65, and the multiple groups of connecting rods 66 are arranged at equal intervals. Sockets for connecting the multiple groups of connecting rods 66 are opened on the side of the fixed baffle 63 adjacent to the first cylinder 62. The stability of the movable plate 65 is ensured by the multiple groups of connecting rods 66.

[0024] Multiple groups of first buffer springs 68 are arranged between the fixed baffle 63 and the limit buffer plate 67, and multiple groups of second buffer springs 610 are arranged between the movable plate 65 and the movable buffer plate 69. The first buffer springs 68 facilitate buffering after the paper box hits the limit buffer plate 67, thereby avoiding the collision and causing the angle of the paper box to shift. At the same time, the second buffer springs 610 facilitate limiting the position of the paper box when the vacuum suction cup 49 is adsorbed, avoiding the position of the paper box from shifting, and improving the stability of the adsorption of the paper box.

[0025] The flipping mechanism 4 includes a lifting block 42 and a telescopic cylinder 45. The lifting block 42 is threadedly connected to the lower end of the screw 41. The telescopic cylinder 45 is installed on one side of the moving block. The telescopic end of the telescopic cylinder 45 passes through the lifting block 42 and is installed with a mounting plate 46. A second motor 47 is installed on one side of the mounting plate 46. The output shaft of the second motor 47 is connected to a rotating shaft seat 48. One side of the rotating shaft seat 48 is provided with multiple groups of vacuum suction cups 49. The telescopic cylinder 45 facilitates the position adjustment of the vacuum suction cup 49, and then facilitates the vacuum suction cup 49 to resist the paper box, so that the vacuum suction cup 49 adsorbs the paper box under the reaction force of the movable buffer plate 69, thereby improving the stability of the paper box adsorption.

[0026] The flipping mechanism 4 also includes a first motor 44, a screw 41 and a guide rod 43. The lower end of the screw 41 is threadedly connected to the lifting block 42. A mounting groove 3 for installing the screw 41 and the guide rod 43 is provided on one side of the bracket 2. A through hole for the guide rod 43 to slide through is provided on the upper surface of the lifting block 42. The upper end of the screw 41 penetrates the bracket 2 and is driven by the first motor 44. The screw 41 is driven by the first motor 44 to facilitate the lifting block 42 to rise and fall, thereby facilitating the flipping of the paper box.

[0027] The inner cavity of the protective frame 1 is provided with a first deceleration plate 8 and a second deceleration plate 9. A first blocking member 10 is provided above the first deceleration plate 8, and a carton correction mechanism 12 is provided above the second deceleration plate 9. A second blocking member 11 is provided between the carton correction mechanism 12 and the fixed baffle 63. The second deceleration plate 9 facilitates the deceleration of the carton passing through the first blocking member 10, and then the carton is adjusted to the correct angle through the carton correction mechanism 12 after being blocked by the second blocking member 11, so as to facilitate subsequent flipping.

[0028] The first blocking member 10 and the second blocking member 11 both include symmetrically arranged electric push rods and baffles. The width of the first deceleration plate 8 is smaller than that of the second deceleration plate 9. The first deceleration plate 8 facilitates the deceleration of the passing paper box, thereby facilitating the blocking by the first blocking member 10.

[0029] When in use, the carton is conveyed to the bottom of the bracket 2 by the conveyor belt 7 and blocked by the limit mechanism 6, and then the telescopic cylinder 45 drives the mounting plate 46 to approach the carton, so that the vacuum suction cup 49 on the rotating shaft seat 48 touches the carton and adsorbs the carton. At the same time, one side of the carton touches the movable buffer plate 69 and squeezes the second buffer spring 610. After the telescopic cylinder 45 is reset, the first motor 44 drives the screw 41 to rotate forward to drive the lifting block 42 to rise, and then the second motor 47 drives the rotating shaft seat 48 to rotate to complete the flipping of the carton. After the flipping is completed, the first motor 44 reverses and drives the screw 41 to drive the lifting block 42 to descend, and then the vacuum The suction cup 49 releases the adsorption force, causing the carton to fall onto the conveyor belt 7, and the first cylinder 62 resets to raise the limit buffer plate 67, thereby facilitating the transportation of the carton. When the first cylinder 62 resets, the first blocking member 10 and the second blocking member 11 open at the same time to release a carton to pass through. The carton passing through the first blocking member 10 is decelerated by the second deceleration plate 9 and then corrected by the carton correction mechanism 12, thereby being blocked by the second blocking member 11. The carton passing through the second blocking member 11 is blocked by the limit mechanism 6, and then the carton is flipped over, thereby improving the efficiency of flipping the carton, avoiding the angle change of the carton before adsorption, and thereby improving the stability of the flipping.
