DETAILED DESCRIPTION

[0036] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0037] like Figure 1 As shown, the utility model provides a box closing mechanism for a vial packaging box, comprising a box closing module 1 and a tongue pushing module 2. The box closing module 1 and the tongue pushing module 2 are respectively located above and on one side of the packaging box conveyor belt, and realize the online box closing action as the packaging box is conveyed in a straight line.

[0038] In this application, please refer to the attached Figure 2-5The box closing module 1 includes at least one box closing part 10, and the box closing part 10 includes a first cylinder 102, a second cylinder 104, a pressure block 107 and a hook-shaped column 108. The second cylinder 104 is connected to the output end of the first cylinder 102 so that the second cylinder 104 moves in the vertical direction. The pressure block 107 and the hook-shaped column 108 are respectively connected to the output end of the second cylinder 104 so that the pressure block 107 and the hook-shaped column 108 move in the vertical direction respectively. The pressure block 107 is used to press down the top page of the packaging box, and the hook-shaped column 108 is used to fold the insert tongue of the packaging box and hook the insert tongue.

[0039] It should be noted that the hook-shaped column 108 is composed of a column and a hook claw at its bottom. When the hook-shaped column 108 descends, the hook claw at its bottom hooks with the edge of the tongue, thereby driving the top leaf and the tongue to rise together when the hook-shaped column 108 rises.

[0040] It is easy to understand that the lowest point of the hook-shaped column 108 is lower than the lowest point of the pressing block 107, so that the hook-shaped column 108 can hook the insert tongue before the pressing block 107 presses the top leaf down to the horizontal plane.

[0041] In this application, please refer to the attached Figure 6 and Figure 7 The tongue pushing module 2 includes at least one tongue pushing portion 20, and the tongue pushing portion 20 includes a third cylinder 202 and a tongue pushing block 203. The tongue pushing block 203 is connected to the output end of the third cylinder 202 so that the tongue pushing block 203 moves in a horizontal direction. The tongue pushing block 203 is used to push the insertion tongue into the box body.

[0042] Among them, the closing action of each component is specifically configured as follows: when the first cylinder 102 contracts and the second cylinder 104 contracts, the pressure block 107 and the hook-shaped column 108 are at the highest point; when the first cylinder 102 extends and the second cylinder 104 extends, the pressure block 107 and the hook-shaped column 108 are at the lowest point; when the first cylinder 102 extends and the second cylinder 104 contracts, the pressure block 107 and the hook-shaped column 108 are at the middle point.

[0043] In order to avoid interference between the components during different actions, when the pressure block 107 and the hook-shaped column 108 are at the highest point or the lowest point, the third cylinder 202 contracts and the tongue pusher 203 is separated from the hook-shaped column 108; when the pressure block 107 and the hook-shaped column 108 are at the middle point, the third cylinder 202 extends and the tongue pusher 203 is interlaced with the hook-shaped column 108.

[0044] The closing process of the box closing mechanism is described in detail below: when the packaging box filled with vials is conveyed between the box closing portion 10 and the tongue pushing portion 20, the top page of the packaging box is in a tilted state under the cover of other gear levers, that is, at this time, the top page and the inserting tongue are in the same plane and at an angle with the horizontal plane, at this time, the first cylinder 102 and the second cylinder 104 are both in a contracted state, the pressing block 107 and the hook-shaped column 108 are at the highest point, and are separated from the top page and the inserting tongue. First, the first cylinder 102 and the second cylinder 104 are fully extended at the same time, and the pressing block 107 and the hook-shaped column 108 gradually descend. In this process, the pressing block 107 first presses the edge of the top page and presses the top page down, and the hook-shaped column 108 presses the plug tongue down so that the plug tongue is bent downward at the edge of the top page. At the same time, the hook-shaped column 108 slides downward relative to the plug tongue until the hook claw of the hook-shaped column 108 hooks the lower edge of the plug tongue and the pressing block 107 flattens the top page, completing the first stage of action. At this time, the pressing block 107 and the hook-shaped column 108 are at the lowest point; then the second cylinder 104 is fully retracted, and the pressing block 107 and the hook-shaped column 108 gradually rise. In this process, the hook-shaped column 108 drives the bent plug tongue to gradually tilt upward, and the top page opens upward accordingly, until the bottom of the plug tongue is completely higher than the top edge of the packaging box body, and the first stage of action is completed. The second stage of action is completed, at which time the pressing block 107 and the hook-shaped column 108 are at the middle point; then the third cylinder 202 is fully extended, driving the tongue pushing block 203 to contact the raised inserting tongue and push it in the direction of the packaging box body, so that the inserting tongue is separated from the hook-shaped column 108, and the lower edge of the inserting tongue gradually enters the inner side of the packaging box body, while the top page is still pressed by the pressing block 107, completing the third stage of action; then the second cylinder 104 is fully extended again, and under the restriction of the tongue pushing block 203, the inserting tongue is pushed into the interior of the packaging box body by the descending pressing block 107, and at the same time, the top page is pressed against the top surface of the packaging box body by the pressing block 107, completing the fourth stage of action and realizing the closing of the box; finally, the first cylinder 102, the second cylinder 104, and the third cylinder 202 are reset respectively, which is convenient for the next closing action.

[0045] Through the cooperation of the first cylinder 102 and the second cylinder 104, the actions of pressing down the top page and hooking the tongue are both performed in the vertical direction. After the actions are decomposed, only the third cylinder 202 is needed in the horizontal direction, which requires space, especially above the packaging box, to reduce the space occupied on both sides of the packaging box. This realizes the automatic box closing action while simplifying the space layout and reducing space occupation.

[0046] In this application, please refer to the attached Figure 3-Figure 5The closing box part 10 also includes: a first panel 101, the first cylinder 102 is fixed on the lower surface of the first panel 101; a first bracket 103, arranged along a horizontal plane, the output end of the first cylinder 102 is connected to the top surface of the first bracket 103, and the second cylinder 104 is arranged on the side of the first bracket 103; a second panel 105, arranged along a horizontal plane, and fixed at the output end of the second cylinder 104; wherein the pressing block 107 and the hook-shaped column 108 are respectively connected to the bottom surface of the second panel 105.

[0047] Specifically, the first panel 101 can be conveniently installed with the first cylinder 102, and a push plate is added at the bottom of the first panel 101 on the side away from the second cylinder 104. Before the first cylinder 102 and the second cylinder 104 extend, the push plate can be used to support the side of the packaging box body to prepare for the top page to be pressed down, and initially prevent the top page from shifting. The arrangement of the first bracket 103 allows the second cylinder 104 and the first cylinder 102 to be arranged vertically respectively. The second panel 105 provides a horizontal reference surface to further ensure the movement direction of the pressing block 107 and the hook-shaped column 108.

[0048] In this application, please refer to the attached Figure 3-Figure 5 The closing box portion 10 also includes: a second bracket 106, which is arranged on the bottom surface of the second panel 105, and the middle of one side of the second bracket 106 extends downward to form a middle ridge 1061; wherein the pressing block 107 is fixed to the side of the middle ridge 1061, and the bottom of the pressing block 107 protrudes from the bottom of the middle ridge 1061; wherein a plurality of hook-shaped columns 108 are arranged at intervals at the bottom of the second bracket 106.

[0049] Specifically, the second bracket 106 serves as a common carrier of the pressing block 107 and the hook-shaped column 108, ensuring that the two move synchronously while acting on the top page and the plug tongue respectively, so that the pressing block 107 and the hook-shaped column 108 act synchronously to avoid delayed action. The middle convex strip 1061 is used to locate the position of the pressing block 107, so that when the pressing block 107 presses down the top page, it acts on the middle position of the lower top page; a plurality of hook-shaped columns 108 ensure the accuracy of hooking the lower edge of the plug tongue to prevent the hook from coming off.

[0050] For further information, please see the attached Figure 3 and Figure 4 , both sides of one side of the second bracket 106 extend downward to form edge ridges 1062, and a sealing block 109 is provided on the side of the edge ridge 1062, and the bottom of the sealing block 109 is aligned with the bottom of the pressing block 107. First, the edge ridge 1062 is located at the edge of the second panel 105, corresponding to the edge of the top page of the packaging box. When the pressing block 107 presses down the top page to close the box, the sealing blocks 109 on both sides help the pressing block 107 to press the edge of the top page, thereby improving the accuracy of closing the box and ensuring that the packaging box is completely closed.

[0051] For further information, please see the attached Figure 3 A tongue-blocking plate 110 is provided at the bottom of the second panel 105 and at one side of the second bracket 106. Specifically, the tongue-blocking plate 110 is a sheet-like structure, and its bottom is bent toward the side away from the hook-shaped column 108, and is used to transitionally contact the edge of the plug tongue; when the second panel 105 is lowered along with the second cylinder 104, the surface of the tongue-blocking plate 110 contacts the edge of the plug tongue, shielding the edge of the plug tongue to prevent the plug tongue from being skewed, facilitating the smooth bending of the plug tongue, and also facilitating the smooth insertion of the plug tongue into the body of the packaging box.

[0052] Specifically, in order to further improve the closing efficiency, as shown in the attached Figure 1 and Figure 2 As shown, when at least two closing box parts 10 are provided, two adjacent closing box parts 10 are connected by a first connecting member 11. In this embodiment, the first connecting member 11 is connected to the top of the first panel 101 by a common fixing member such as a bolt; one first connecting member 11 can connect at least two closing box parts 10, and the closing box module 1 formed as a whole by one connecting member 11 and two closing box parts 10 can be disassembled as a whole, which is convenient for assembly in an automated device, and the first connecting member 11 can also be used as a handle to realize the transportation or hoisting of the entire closing box part 10.

[0053] In this application, please refer to the attached Figure 7 In order to further match the height between the third cylinder 202 and the packaging box when the tongue is inserted, the tongue pushing portion 20 also includes a third panel 201, a third bracket 2011 is arranged on the top of the third panel 201, and the third cylinder 202 is arranged on the top of the third bracket 2011; the third bracket 2011 further raises the height of the third cylinder 202 and also reserves space on the third panel 201.

[0054] Further, as a specific embodiment of the present application, please refer to the attached Figure 7 The tongue-pushing part 20 further includes a fourth bracket 204, which is arranged on a side of the third bracket 2011 facing the output end of the third cylinder 202, and a position sensor 205 matching the tongue-pushing block 203 is arranged on the fourth bracket 204. The fourth bracket 204 not only provides a relatively stable motion platform for the tongue-pushing block 203, but also provides a relatively horizontal mounting carrier for the position sensor 205, so that the position sensor 205 can transmit the position change of the tongue-pushing block 203 to the control system in time, so that the control system can make corresponding control actions on the working state of each cylinder.

[0055] Furthermore, in order to ensure the structural strength of the tongue-pushing block 203 and avoid the movement interference between the tongue-pushing block 203 and the hook-shaped column 108, a plurality of tongue-pushing teeth 2031 are arranged on the side of the tongue-pushing block 203 away from the third cylinder 202. Specifically, when the tongue-pushing block 203 pushes the insertion tongue into the inner side of the packaging box body, the tongue-pushing teeth 2031 are inserted into the gap between two adjacent hook-shaped columns 108, so that the hook-shaped column 108 will not collide with the tongue-pushing block 203 during the fourth stage of action.

[0056] In this application, please refer to the attached Figure 6 When at least two tongue-pushing parts 20 are provided, two adjacent tongue-pushing parts 20 are connected by a second connecting member 21. The second connecting member 21 connects two adjacent tongue-pushing parts 20 in a straight line, so that the extension direction of the entire tongue-inserting module 2 is parallel to the extension direction of the box-closing module 1 and the transportation direction of the packaging box, which is beneficial to the assembly line work and improves the box-closing efficiency.

[0057] In summary, the present application utilizes the mutual cooperation of the first cylinder, the second cylinder and the third cylinder to realize the bending of the top page and the tongue of the packaging box, the tongue insertion and the box closing actions, which is conducive to the use of the automated packaging production line of the vials and improves the packaging efficiency of the vials.
