Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it by referring to the description.

As shown in Figure 1, the utility model provides a double-sided labeling device for packaging boxes, including a front transmission mechanism 110, a rear transmission mechanism 120, a first labeling mechanism 130, a second labeling mechanism 140 and a turning mechanism 150 .

The first labeling mechanism 130 is located above the front conveying mechanism 110. The packaging box 160 to be labeled is placed on the front conveying mechanism 110, and the packaging box 160 is conveyed from left to right by the front conveying mechanism 110. When the packaging box 160 passes through When the first labeling mechanism 130 is below, the first labeling mechanism 130 sticks the label on the front of the packaging box 160 .

The turning mechanism 150 is arranged between the front conveying mechanism 110 and the rear conveying mechanism 120 , and the front conveying mechanism 110 continues to convey the package box 160 with the label on the front until it is delivered to the turning mechanism 150 . The overturning mechanism 150 moves the packaging box 160 onto the rear transfer mechanism 120 and turns the packaging box 160 180° so that the back side of the packaging box is facing up.

The second labeling mechanism 140 is located above the rear conveying mechanism 120 . The rear conveying mechanism 120 conveys the packaging box 160 to the right, and when the packaging box 160 passes under the second labeling mechanism 140 , the second labeling mechanism 140 sticks the label on the back of the packaging box.

As shown in Figure 2, the structures of the first labeling mechanism 130 and the second labeling mechanism 140 are exactly the same, taking the first labeling mechanism 130 as an example, the first labeling mechanism 130 includes an unwinding roller 131, Buffer roller 132 , guide roller 133 , labeling roller 134 , driving roller 135 and winding roller 136 . The unwinding roller 131 is wound with a label paper tube, and the label paper is released from the unwinding roller 131, passes through buffer roller 132, guide roller 133, labeling roller 134 and driving roller 135 successively, and is wound on the winding roller 136 again. When the packaging box 160 passed below the labeling roller 134, the label on the label paper was pasted on the packaging box 160 by the labeling roller 134.

The front conveying mechanism 110 includes a first conveyor belt, which can convey the packaging box from the front end to the rear end of the first conveyor belt, and perform labeling when the packaging box 160 passes the first labeling mechanism 130 .

As shown in Figure 4, the rear transmission mechanism 120 includes a second conveyor belt 121 and a third conveyor belt 122, the second conveyor belt 121 and the third conveyor belt 122 are arranged in parallel, and there is a space between the second conveyor belt 121 and the third conveyor belt 122. There is a certain gap. Both ends of the second conveyor belt 121 and the third conveyor belt 122 are flush. The second conveyor belt 121 and the third conveyor belt 122 move synchronously, and the packaging box 160 is placed on the second conveyor belt 121 and the third conveyor belt 122, and the packaging box is conveyed from left to right by the second conveyor belt 121 and the third conveyor belt 122 working together.

As shown in FIG. 3 , the turning mechanism 150 includes a turning plate 151 , which is Y-shaped and includes three supporting plates, and the angle between two adjacent supporting plates is 120°. A rotating shaft 152 is fixed in the middle of the turning plate 151 , and both ends of the rotating shaft 152 are rotatably supported on the brackets, so that the turning plate 151 can rotate around the rotating shaft 152 .

The rotating shaft is fixedly connected with the sheave 153 and the rotating shaft 152 . The sheave 153 is provided with three long grooves 154 uniformly distributed around the circumference, and the angle between two adjacent long grooves 154 is 120°. The rotating arm 155 cooperates with the sheave 153. When the rotating arm 155 rotates one turn, the sheave 153 rotates 120°, which drives the rotating shaft 152 and the turning plate 151 to rotate 120° together. The rotating arm 155 is driven by a stepping motor or a servo motor, and rotates one circle at a time.

As shown in Fig. 4, a support plate of the said turnover plate 151 in the initial state is arranged horizontally, and the support plate is positioned at the tail end of the first conveyor belt 111, after the first conveyor belt 111 transports the packing box 160 to the tail end, the packing box 160 will slide down to the support plate of the turnover plate 151, then the turnover plate 151 will rotate 120° around the rotating shaft 152, and drive the packaging box 160 to rotate 120°, so that the packaging box 160 is positioned above the second conveyor belt 121 and the third conveyor belt 122, and then The packing box 160 turns over and falls by inertia, and realizes the overall turning of 180°, and the two sides of the packing box 160 land on the second conveyor belt 121 and the third conveyor belt 122 respectively. During the turning process, the turning plate 151 is always located between the second conveyor belt 121 and the third conveyor belt 122 without interference. The second conveyor belt 121 and the third conveyor belt 122 continue to convey the packaging box 160 backward. The packaging box 160 can be turned over by the turning plate 151 .

Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and implementation. It can be applied to various fields suitable for the utility model. Additional modifications can readily be made by those skilled in the art. Therefore, the invention should not be limited to the specific details and examples shown and described herein, without departing from the general concept defined by the claims and their equivalents.
