Technical Field

[0001] The present application relates to the technical field of packaging box separation, and in particular to a one-piece packaging box separation device. Background Art

[0002] With the development of dry-glue transfer technology, the requirements for automation of printing equipment are getting higher and higher. In order to simplify the operation of employees, transfer equipment tends to be automated and simplified. In the printing process of related dry-glue transfer printing machines, due to the increasing number of packaging boxes, in order to ensure that different types of packaging boxes can be separated smoothly in an ideal state, different separation structures need to be designed according to the situation.

[0003] Especially, the one-piece packaging box among the packaging boxes has a cover, a folded edge and a box body. The one-piece packaging boxes are stored by stacking before feeding. Specifically, the stacking method of the one-piece packaging boxes is that multiple covers and multiple box bodies are stacked together respectively.

[0004] The relevant separation method of one-piece packaging boxes is: according to different products, adjust the structure of the sub-cover to ensure that the one-piece packaging box separation achieves the ideal effect. Each adjustment of the sub-cover structure takes an hour or even more, which will cause huge production capacity losses. At the same time, the cup separation wheel must be customized according to different products. The effect of the cup separation wheel for some special one-piece packaging boxes is not very suitable. Sometimes the packaging boxes cannot be separated or multiple layers of packaging boxes fall together, which affects the improvement of product production efficiency and defective rate. When using the cup separation wheel, the debugging personnel are required to adjust each position according to the actual situation. However, due to the accumulation of various factors during the manual debugging process, the separation effect will also vary greatly. In order to achieve a better separation effect, a lot of man-hours are often required for testing. Summary of the invention

[0045] The embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0046] Reference Figure 1 , 3 As shown, in some embodiments of the present application, a one-piece packaging box separation device is provided, including: a cover shell 11, a support base 12, a transmission unit 13 and an insertion and separation tip 14, and the cover shell 11, the transmission unit 13 and the insertion and separation tip 14 are installed on the support base 12.

[0047] Specifically, the support base 12 includes a bottom plate 121, a column 122 and a connecting plate 123. The bottom plate 121 and the connecting plate 123 are connected through the column 122. The bottom plate 121 and the connecting plate 123 are arranged in parallel, and the column 122 is arranged vertically to the bottom plate 121 and the connecting plate 123. The cover 11 is arranged between the bottom plate 121 and the connecting plate 123, and the cover 11 is used to protect the transmission unit 13.

[0048] The transmission unit 13 is connected to the insertion and separation tip 14, and the insertion and separation tip 14 is installed in the bottom plate 121. Driven by the transmission unit 13, the insertion and separation tip 14 can extend from the bottom plate 121. The cross-sectional area of ​​the insertion and separation tip 14 gradually decreases along the extension direction thereof, so that the end of the insertion and separation tip 14 away from the support seat 12 forms a tip. Driven by the transmission unit 13, the tip of the insertion and separation tip 14 can gradually extend between the folded edges of the two stacked one-piece packaging boxes. As the cross-sectional area of ​​the insertion and separation tip 14 extending between the folded edges gradually increases, the interval between the two folded edges is forced, thereby separating the two stacked one-piece packaging boxes.

[0049] Furthermore, the insertion and separation tip 14 has a first insertion and separation surface 141 and a second insertion and separation surface 142 which are arranged opposite to each other, and the folded edges of the two adjacent conjoined packaging boxes are correspondingly attached to the first insertion and separation surfaces 141 and the second insertion and separation surfaces 142. The first insertion and separation surfaces 141 and the second insertion and separation surfaces 142 gradually approach each other along the extension direction of the insertion and separation tip 14, so that the first insertion and separation surfaces 141 and the second insertion and separation surfaces 142 form an angle.

[0050] Specifically, the insertion and splitting tip 14 reciprocates along a horizontal straight line under the drive of the transmission unit 13. The first insertion and splitting surface 141 and the second insertion and splitting surface 142 are arranged up and down, and the first insertion and splitting surface 141 and the second insertion and splitting surface 142 are respectively arranged on both sides of the horizontal straight line. The first insertion and splitting surface 141 and the second insertion and splitting surface 142 are both inclined relative to the horizontal straight line.

[0051] More specifically, refer to Figure 6 As shown, the angle α formed by the first split surface 141 and the horizontal line is smaller than the angle β formed by the second split surface 142 and the horizontal line. As the split tip 14 gradually extends between the two folded edges, the offset distance of the second split surface 142 attached to the folded edge of the one-piece packaging box is greater than the offset distance of the first split surface 141 attached to the folded edge of the one-piece packaging box.

[0052] At the same time, the one-piece packaging box separation device also includes a blowing unit, the air outlet of the blowing unit is arranged close to the second insertion surface 142, so that the gas blown out by the blowing unit will flow into the one-piece packaging box close to the second insertion surface 142.

[0053] In this solution, gas is input between the two one-piece packaging boxes, so that the air pressure inside the two one-piece packaging boxes increases, and the air pressure pushes the two one-piece packaging boxes to separate. The air outlet is arranged close to the second insertion surface 142, so that the one-piece packaging box attached to the second insertion surface 142 is offset from the support seat 12 by a larger distance, so that more gas discharged from the blowing unit flows into the space between the two one-piece packaging boxes. The gas turbulence is used to promote the separation of the two one-piece packaging boxes.

[0054] In a specific embodiment, the first insertion and separation surface 141 is located above the second insertion and separation surface 142. The support base 12 has a gas guiding surface 1214, which is a chamfered surface formed between the bottom surface of the support base 12 and the side surface where the insertion and separation tip 14 extends, and the gas outlet is provided on the gas guiding surface 1214. The gas guiding surface 1214 is provided close to the second insertion and separation surface 142, so that the gas discharged from the gas outlet is discharged to the second insertion and separation surface 142, and the gas flows into between the two connected packaging boxes.

[0055] Specifically, an air duct 1213 is provided inside the support base 12, and the air duct 1213 forms an air outlet on the air guide surface 1214, and the air duct 1213 forms an air inlet on the top surface of the support base 12. An air pipe joint 15 is installed on the air inlet, and the air pipe joint 15 is connected to the blowing device through an air pipe. The air pipe joint 15 is located between the bottom plate 121 and the connecting plate 123. Figure 2 As shown, the cover shell 11 includes a plate body 111, which is arranged between the bottom plate 121 and the connecting plate 123. A clearance window 113 is opened on the plate body 111, and the air pipe connected to the air pipe connector 15 can pass through the clearance window 113 to connect with the blowing device.

[0056] In another specific embodiment, the air outlet is provided on the second insertion surface 142. The airflow can be discharged from the second insertion surface 142, and the airflow enters between the two connected packaging boxes. Specifically, the airway is opened on the bottom plate 121 and the insertion tip 14, and openings are formed on the surfaces of the bottom plate 121 and the insertion tip 14. During the sliding process of the insertion tip 14, the two openings are always in a connected state, but during the sliding process of the insertion tip 14, the connecting area of ​​the two openings changes. The surfaces of the bottom plate 121 and the insertion tip 14 that are in contact with each other need to be sealed to prevent airflow leakage. When the insertion tip 14 reciprocates, the air outlet can still eject airflow, and the trachea and the trachea joint 15 remain stationary relative to the support seat 12.

[0057] It can be understood that the airway can be provided on both the bottom plate 121 and the insertion and separation tip 14, or the airway can be provided on the insertion and separation tip 14 alone to simplify the airway structure.

[0058] Furthermore, the bottom plate 121 is provided with a notch that matches the insertion and separation tip 14. The plate body 111 is also provided with an avoidance groove 112, which matches the notch to form a sliding hole for the insertion and separation tip 14 to slide. When the insertion and separation tip 14 is installed in the notch, the insertion and separation tip 14 is higher than the top surface of the bottom plate 121, and the part of the insertion and separation tip 14 that is higher than the top surface of the bottom plate 121 is located in the avoidance groove 112.

[0059] In some embodiments of the present application, Figure 4 , 5 As shown, the transmission unit 13 includes a slider 133, and the slider 133 is connected to the plug-in tip 14. A guide groove is provided on the bottom plate 121, and the guide groove is connected to the notch. The slider 133 is connected to the plug-in tip 14, and specifically, the slider 133 has a mounting portion 1332, and the mounting portion 1332 is connected to the plug-in tip 14. The slider 133 slides in the guide groove along the extension direction of the plug-in tip 14.

[0060] More specifically, the guide groove has a first guide groove 1211 and a second guide groove 1212 that are interconnected. The slider 133 is T-shaped, and the shapes of the first guide groove 1211 and the second guide groove 1212 match the slider 133, so that a part of the slider 133 slides in the first guide groove 1211, and the other part slides in the second guide groove 1212.

[0061] Furthermore, the transmission unit 13 further includes a rotating shaft 131 and an eccentric roller 132. A pulley 1323 is provided on one end of the eccentric roller 132, and the other end is connected to the rotating shaft 131. The axis of the pulley 1323 is not in the same straight line direction as the axis of the rotating shaft 131.

[0062] The slider 133 is provided with a slide groove 1331, which is opened on the part of the slider 133 located in the first guide groove 1211. Specifically, the extension direction of the slide groove 1331 is perpendicular to the extension direction, and the pulley 1323 is located in the slide groove 1331, and the pulley 1323 slides along the extension direction of the slide groove 1331. The pulley 1323 slides back and forth in the slide groove 1331, and slides back and forth along the extension direction under the limitation of the guide groove.

[0063] Furthermore, the eccentric roller 132 has a mounting groove 1321 on the upper side thereof, and a connecting portion 1322 is received in the mounting groove 1321, and the connecting portion 1322 is connected to the pulley 1323. A portion of the pulley 1323 passes through the body of the eccentric roller and extends into the mounting groove 1321, and the body of the eccentric roller is connected to the pulley 1323 through the connecting portion 1322. Exemplarily, the body of the eccentric roller is connected to the pulley 1323 by a screw, the pulley 1323 has a screw, the connecting portion 1322 is a nut, the screw extends into the mounting groove 1321, and the nut is threadedly connected to the screw extending into the mounting groove 1321, thereby achieving a fixed connection between the body of the eccentric roller and the pulley 1323.

[0064] The installation groove 1321 is provided to receive the connection portion 1322 , and the installation groove 1321 plays a role of making way, so as to facilitate the operator to implement the operation of connecting the body of the eccentric roller with the pulley 1323 through the connection portion 1322 .

[0065] The above embodiments are used to further illustrate the present application, but the present application is not limited to these specific implementations. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be understood to be within the scope of protection of the present application.
