In the following description, many specific details are provided to provide a full understanding of the example embodiments of the present disclosure. However, those skilled in the art will appreciate that the technical solutions of the present disclosure may be practiced while omitting one or more of the specific details, or other methods, components, steps, etc. may be adopted. In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0030] like Figures 1 to 7 As shown, a packaging device for plastic boxes includes a frame 1, a packaging assembly 2, a driving component 3, a cover pushing assembly 4, a feeding assembly 5, and a discharging assembly 6. The packaging assembly 2 is arranged above the frame 1, and the driving component 3 is located at one side of the packaging assembly 2.

[0031] In the present invention, the packaging component 2 includes a vertically movable pressure plate 21, an opening 211 is provided on one side of the pressure plate 21, a feeding track 22 fixedly mounted on the frame 1 is arranged on the inner side of the opening 211, a limiting block 212 is arranged at the bottom of one side of the pressure plate 21, a wedge block 23 is arranged at the upper part of one side of the pressure plate 21, a rocker arm 24 rotatably connected to the frame 1 through a return spring is arranged on one side of the limiting block 212, a limiting block 241 is fixedly connected to the bottom of the rocker arm 241, and the limiting block 241 can support the bottom of the limiting block 212 to limit the downward movement of the pressure plate 21.

[0032] Furthermore, in order to enable the pressing plate 21 to move vertically, a guide rod 26 is fixedly connected to the top of the frame 1 , and the guide rod 26 is vertically movably plugged into one side of the pressing plate 21 .

[0033] In the present invention, the driving component 3 includes a turntable 31, a power component 32 that can drive the turntable 31 to rotate, and a spring 2 35 arranged at the upper end of the pressure plate 21 and pressed against the top of the pressure plate 21 and the top of the frame 1. The side wall of the turntable 31 is fixedly connected with a short rod 33 and a long rod 34. The short rod 33 can push the rocker arm 24 to rotate so that the limit block 241 is separated from the limit block 1 212. The long rod 34 can push the wedge block 23 to move the pressure plate 21 upward so that the limit block 241 supports the bottom of the limit block 1 212.

[0034] The power component 32 uses a rotating driving component, such as a servo motor, and the power component 32 is fixedly installed on the frame 1. When in use, the power component 32 can drive the turntable 31, the short rod 33 and the long rod 34 to rotate. Figure 5As shown, in the initial state, the limit block 241 presses against the bottom of the limit block 1 212, the spring 2 35 is in a compressed state, the turntable 31 rotates clockwise, and the short rod 33 pushes the long rod 34 first, causing the swing rod 24 to swing counterclockwise, so that the limit block 241 is separated from the limit block 1 212. At this time, under the action of the spring 2 35, the pressure plate 21 moves downward, and then the long rod 34 pushes the wedge block 23, and the pressure plate 21 is driven to move upward by the wedge block 23. During the upward movement of the pressure plate 21, the limit block 1 212 will push the limit block 241 upward, and finally when the long rod 34 is separated from the wedge block 23, the limit block 241 will press against the bottom of the limit block 1 212 again.

[0035] That is, the driving component 3 is used to drive the pressing plate 21 to move vertically, the short rod 33 pushes the swing rod 24, the pressing plate 21 moves downward, and the long rod 34 pushes the wedge block 23, the pressing plate 21 moves upward. The packaging box 100 is placed on the feeding track 22, and the items to be packaged are placed inside the box body 101 of the packaging box 100. The driving component 3 drives the pressing plate 21 to move downward and press on the box cover 102 of the packaging box 100, so that the box body 101 and the box cover 102 of the packaging box 100 are closed.

[0036] It should be noted that, in order to prevent the long rod 34 from pushing the swing rod 24 , the long rod 34 may be disposed on the front side of the swing rod 24 .

[0037] In the present invention, the cover push assembly 4 is arranged on one side of the pressure plate 21, and the cover push assembly 4 includes a movable rod 41 which is horizontally movably plugged into the pressure plate 21, and a spring 42 which is pressed together with the pressure plate 21 and the movable rod 41 is sleeved on the outer side of the movable rod 41. Since when the items to be packaged are placed inside the packaging box 100, the angle between the box body 101 and the box cover 102 is an obtuse angle, when the pressure plate 21 moves downward, in order to enable the box body 101 and the box cover 102 of the packaging box 100 to be closed, it is necessary to make the angle between the box body 101 and the box cover 102 an acute angle. When the short rod 33 pushes the rocker arm 24 to rotate, the rocker arm 24 can push the movable rod 41 to move, and when the movable rod 41 moves, it pushes the box cover 102 of the packaging box 100 to make the angle between the box body 101 and the box cover 102 become an acute angle.

[0038] Furthermore, in order to prevent the movable rod 41 from colliding with the downwardly moving pressing plate 21 , a avoiding opening 213 for the movable rod 41 to pass vertically is opened on one side of the pressing plate 21 .

[0039] In the present invention, the feed assembly 5 is arranged on the side of the packaging assembly 2 away from the driving component 3, and is used to feed the items to be packaged into the box body 101. It includes a feed plate 51 located on one side of the opening 211 and fixedly connected to the frame 1, a barrel 52 is fixedly connected to the top of the feed plate 51, and a push plate 53 that can reciprocate along the feed plate 51 is arranged inside the feed plate 51, and the push plate 53 pushes the items to be packaged into the box body 101. The feed assembly 5 also includes a push rod 54, one end of which is fixedly connected to the wedge block 23, and the other end of the push rod 54 is vertically movably inserted on the push plate 53. The wedge block 23 is movably inserted into the inside of the pressing plate 21 through a spring 25 arranged inside the pressing plate 21. The bottom of the wedge block 23 has an inclined surface 231, and the long rod 34 pushes the inclined surface 231 to move the wedge block 23 toward the inside of the pressing plate 21.

[0040] The articles to be packaged are placed inside the barrel 52, the box body 101 is placed on the feeding track 22, and the push plate 53 is located below the barrel 52. When the long rod 34 pushes the wedge block 23 to move the pressing plate 21 upward, the long rod 34 first contacts the inclined surface 231, and at this time, the inclined surface 231 can be pushed to move to the left ( Figure 4 ), so that the push plate 53 can be moved to the left and out of the bottom of the barrel 52 through the push rod 54, and the items to be packaged in the barrel 52 fall onto the feed plate 51, and then the long rod 34 is separated from the wedge block 23, due to the elastic force of the spring 25, the wedge block 23 moves to the right, thereby driving the push plate 53 to move to the right and push the items to be packaged into the box body 101.

[0041] In the present invention, a discharging assembly 6 is arranged below the feeding assembly 5, and the discharging assembly 6 includes a discharging claw 61 rotatably connected to the frame 1 through a second reset spring, a protrusion 62 is fixedly connected to one side of the discharging claw 61, and a short shaft 63 is fixedly connected to the bottom of the push plate 53. The short shaft 63 pushes the protrusion 62 to rotate the discharging claw 61, and the discharging claw 61 can push the packaging box 100 located on the feeding track 22 to move.

[0042] When the push plate 53 moves to the left ( Figure 2 ), the short shaft 63 can push the protrusion 62 to cause the discharge claw 61 to rotate, so that the discharge claw 61 can push the packaging box 100 on the feeding track 22 to move backward to achieve the purpose of transportation, and when the push plate 53 moves to the right, it can also push the protrusion 62, but at this time, the discharge claw 61 rotates in the opposite direction and will not touch the packaging box 100.

[0043] In addition, in order to facilitate the automatic loading of the packaging box 100 , a conveyor belt 7 is provided on the front side of the feeding track 22 for conveying the packaging box 100 .

[0044] Working principle:

[0045] (1) Take a certain working state as the initial state, such as Figure 1-Figure 5 As shown, the items to be packaged are placed inside the box body 101 (not shown in the figure), the angle between the box body 101 and the box cover 102 is an obtuse angle, the push plate 53 is located at the bottom of the barrel 52, and the limit block 241 limits the limit block 1 212.

[0046] (2) First, the short rod 33 pushes the swing rod 24, and the swing rod 24 pushes the movable rod 41, so that the movable rod 41 pushes the box cover 102, so that the angle between the box body 101 and the box cover 102 can be changed to an acute angle, and then the limit block 241 is disengaged from the limit block 1 212, so that the pressing plate 21 moves downward, pressing the box cover 102 downward to close the box body 101 and the box cover 102 to complete the packaging.

[0047] (3) Then, the long rod 34 pushes the wedge block 23 to move the pressure plate 21 upward. During this process, the wedge block 23 will move to the left, driving the push plate 53 to move to the left. The items to be packaged in the barrel 52 fall onto the feed plate 51. In this process, the push plate 53 will drive the short shaft 63 to move to the left. The short shaft 63 pushes the protrusion 62 to rotate the discharge claw 61. The discharge claw 61 pushes the package box 100 that has been packaged in (2) backward, and then the next package box 100 is conveyed to the feed track 22 through the conveyor belt 7. At this time, the angle between the box body 101 and the box cover 102 of this package box 100 is an obtuse angle.

[0048] (4) Then the long rod 34 is separated from the wedge block 23, and the limit block 241 limits the limit block 1 212 again. When separated, the wedge block 23 moves to the right, thereby driving the push plate 53 to push the fallen items to be packaged to the right and push them into the box body 101. That is, the state at this time is restored to (1).

[0049] That is, a working cycle is completed.

[0050] The present invention not only realizes the automatic loading of the articles to be packaged, but also realizes the purpose of using the packaging box 100 to package the articles. In addition, in this process, the box cover 102 can be pushed by the cover pusher assembly 4 to change the angle between the box body 101 and the box cover 102 from an obtuse angle to an acute angle, thereby ensuring smooth packaging. The present invention has a high degree of automation, saves manual operation, and has a high packaging speed.
