[0023] Since the packaging box needs to be squeezed when it is formed, it is inconvenient to use a conveyor belt for transportation throughout the process. At the same time, in the prior art, platforms with a certain hardness are arranged on both sides of the forming mold, and the packaging boxes are pushed after being arranged to make the packaging boxes enter the conveyor belt. However, when the mold squeezes the packaging box downward, the packaging box will move downward, and there is a formed packaging box on the platform on the side of the squeezed packaging box. The formed packaging box will move backward on the platform with a certain hardness due to the influence of the mold force. Therefore, when the formed packaging box is close to the squeezed packaging box, it is easy to cause damage, affecting the shaping effect. Therefore, after research, an automatic shifting and pushing mechanism is provided. When in use, the packaging box is conveyed to the conveying platform by the first conveyor belt, and the second cylinder drives the push plate to slide in the adjusting rail to push the packaging boxes one by one onto the lifting plate for shaping. When the mold is driven by the first cylinder to move downward into the interior of the packaging box, the spring sheet on the upper side of the mold pushes the packaging box on the conveyor belt to one end. The spring sheet has a certain elasticity to avoid damage to the packaging box. At the same time, the nature of the conveyor belt can prevent the packaging box from moving backward, thereby solving the above-mentioned defects.
[0024] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0025] Please refer to Figure 1-Figure 5The embodiment of the utility model provides an automatic shifting and pushing mechanism, including a first conveyor belt 1, which conveys the packaging box from the previous process. A conveying platform 2 is horizontally arranged at the discharge port of the first conveyor belt 1. The packaging box moves from the first conveyor belt 1 to the conveying platform 2. Limiting plates 31 are arranged on both sides of the conveying platform 2. The limiting plates 31 limit the packaging box to prevent it from falling.
[0026] A shaping mechanism is installed at the discharge port of the conveying platform 2. The shaping mechanism is located in the gap between the conveying platform 2 and the conveying soft belt 3. The shaping mechanism pushes the packaging box on the conveying platform 2 to the specified position for shaping. The conveying soft belt 3 is arranged on one side of the shaping mechanism. The second conveying belt 6 is transversely arranged at the discharge port of the conveying soft belt 3. The shaped packaging box passes through the conveying soft belt 3 and enters the second conveying belt 6 for transportation to the next process.
[0027] Limiting plates 31 are arranged on both sides of the conveyor belt 3 , and the limiting plates 31 prevent the formed packaging boxes from falling off the conveyor belt 3 .
[0028] The shaping mechanism includes a support frame 4 arranged on one side of the conveying platform 2, a first cylinder 41 is installed on the upper side of the support frame 4, a piston end of the first cylinder 41 is connected to a mold 42, and the mold 42 is driven by the first cylinder 41 to enter the packaging box located at the lower side of the mold 42 to shape the packaging box.
[0029] In order to enable the mold 42 to push the packaging box downward, a lifting plate 7 is provided at the discharge port of the conveying platform 2. After the packaging box moves to the upper side of the lifting plate 7, the packaging box is located directly below the mold 42. Since a slide bar 71 is provided on the lower side of the lifting plate 7, the slide bar 71 is slidably provided in a slide hole opened in the bottom bar 72. At the same time, a spring 73 is provided at the sliding bottom opened in the bottom bar 72. The upper end of the spring 73 is connected to the lower end of the slide bar 71. When the mold 42 moves downward into the packaging box, as the mold 42 continues to move downward, the mold 42 pushes the lifting plate 7 and the slide bar 71 to slide into the bottom bar 72 and squeezes the spring 73, thereby lowering the height of the packaging box. The downward sliding distance of the slide bar 71 is limited, and it will no longer slide when it slides to the point where the packaging box is formed.
[0030] At this time, since the mounting frame 8 is set at the four side frames located on the lower side of the lifting plate 7, the third cylinder 81 is installed on the upper side of the mounting frame 8, and the piston end of the third cylinder 81 is connected to the pressing plate 82, when the packaging box descends between the four pressing plates 82, the third cylinder 81 pushes the pressing plate 82 to press the outside of the packaging box, combined with the mold 42 inside the packaging box, so as to shape the packaging box.
[0031] After the packaging box is shaped, the mold 42 is slowly moved out of the packaging box, and the spring 73 brings the packaging box back to its original position. The shaped packaging box needs to be moved onto the conveyor belt 3.
[0032] Therefore, a mounting rod 5 is provided on one side of the support frame 4, an adjusting rail 51 is provided on one side of the mounting rod 5, a connecting plate 53 is slidably provided in the adjusting rail 51, the connecting plate 53 is threadedly connected with a reciprocating screw rod 52 rotatably provided in the adjusting rail 51, the rotating shaft of the reciprocating screw rod 52 is connected to the output shaft of the motor, and a second cylinder 54 is installed on one side of the connecting plate 53 at the same time, the piston end of the second cylinder 54 is connected to a push plate 55, the push plate 55 is located on the upper side of the packaging box by the contraction of the second cylinder 54, the push plate 55 is moved to one side of the packaging box on the conveying platform 2 by the rotation of the reciprocating screw rod 52, at this time the second cylinder 54 brings the push plate 55 down, the push plate 55 pushes the packaging box to be finalized onto the lifting plate 7 through the sliding of the connecting plate 53 in the adjusting rail 51, and the finalized packaging box on the lifting plate 7 is pushed onto the conveying soft belt 3 by the new packaging box.
[0033] It is worth mentioning that a spring piece 43 is fixed to one side of the mold 42 by bolts, and the spring piece 43 is in an inclined structure. When the mold 42 descends again into the packaging box, the spring piece 43 pushes the packaging box on the conveyor belt 3 to move forward, which not only pushes the shaped packaging boxes one by one onto the second conveyor belt 6, but also prevents the shaped packaging boxes from being damaged when close to the mold 42.
[0034] When the shaped packaging box enters the second conveyor belt 6, the anti-skid pad 61 provided on the second conveyor belt 6 is used to prevent slipping, thereby increasing the friction coefficient with the bottom of the packaging box and improving the stability of the packaging box during transportation.
[0035] Furthermore, a plurality of screw rods 63 are threadedly connected on one side of the second conveyor belt 6, one end of the screw rod 63 is rotatably connected to the adjustment plate 62, and the screw rod 63 is rotated to make the adjustment plate 62 be located at a suitable position on the upper side of the second conveyor belt 6 to restrict the packaging box and prevent the packaging box from falling.
[0036] In summary, the working principle of an automatic shifting and pushing mechanism of an embodiment of the utility model is as follows: the packaging box is transported to the conveying platform 2 by the first conveyor belt 1, and the packaging box is pushed onto the lifting plate 7 by the push plate 55. The first cylinder 41 brings the mold 42 into the packaging box, so that the lifting plate 7 and the slide bar 71 slide downward, and the third cylinder 81 brings the pressing plate 82 to extrude and shape the four sides of the packaging box. As the lifting plate 7 is reset, the push plate 55 pushes the new packaging box onto the lifting plate 7. At this time, the new packaging box pushes the packaging box on the lifting plate 7 onto the conveyor belt 3, and the packaging box on the conveyor belt 3 is pushed onto the second conveyor belt 6. When the mold 42 continues to descend for a new round of shaping, the spring sheet 43 on the upper side of the mold 42 pushes the packaging box on the conveyor belt 3 to one end. The spring sheet 43 has a certain elasticity to avoid damage to the packaging box. At the same time, the nature of the conveyor belt 3 can prevent the packaging box from moving backward.
[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
