Description

Technical Field

[0001] The utility model relates to the field of packaging, in particular to a rocker arm push rod forming mechanism for the inner tongue of an aircraft box. Background Art

[0002] The traditional airplane box structure is usually connected with the lower box surface and the left and right side surfaces and the left and right inner tongues. After the tray absorbs the lower box surface, the folding forming plate is often designed according to the order of folding corners. Finally, the paper box is pulled downward to complete the folding process. The specific folding process is as follows: Figure 1 As shown, however, a pull-out one-time folding is adopted. When folding the inner tongue on the left and right, most of the time, movable inner tongue folding blocks are used. When folding the inner tongue, the carton needs to first drop and then rise. The movement accuracy of the Z-axis lifting structure of the carton is high, and due to the back-and-forth operation of dropping and rising, the overall forming efficiency of the carton will be low. Therefore, it is urgent to design a mechanism that can complete the left and right inner tongue folding during the transportation of the carton to improve the overall folding efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a rocker push rod forming mechanism for the inner tongue of an airplane box. During the transportation of the paper box, the folding of the left and right inner tongues is completed by the rocker push rod forming module. The rocker push rod forming module can complete the folding of the left and right inner tongues without cooperating with the lifting of the paper box, thereby improving the overall box folding efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a rocker push rod forming mechanism for the inner tongue of an aircraft box, including a folding box handling module and a carton buffer rack for transporting the carton preliminarily folded by the pull-out folding mechanism, the carton transported by the folding box handling module is equipped with two rocker push rod forming modules symmetrical about the carton handling module, the rocker push rod forming module includes a rocker arm movable structure perpendicular to the carton handling module, and the rocker arm movable structure is provided with a push rod for pushing the inner tongue and a rocker arm flipping structure for folding the inner tongue.

[0005] Preferably, the rocker arm movable structure includes a rocker arm telescopic cylinder, which is connected to a rocker arm mounting seat, and the rocker arm mounting seat cooperates with the rocker arm telescopic slide rail on the rocker arm telescopic cylinder, and a rocker arm telescopic positioning rod for limiting the rocker arm mounting seat is also provided on the platform. The rocker arm flipping structure is installed on the rocker arm mounting seat, and a push rod mounting groove is opened on the push rod, and is installed on the rocker arm mounting seat by bolts.

[0006] Preferably, the rocker arm flipping structure includes a rocker arm installed on the rocker arm movable structure through a rotating shaft, and the rocker arm is an obtuse-angled folding block. One end of the rocker arm is connected to the rocker arm flipping cylinder hinged on the rocker arm movable structure, and the other end of the rocker arm is installed with an inner tongue hook plate for folding the inner tongue through a bolt.

DETAILED DESCRIPTION

[0014] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0015] like Figure 1-3As shown, the specific structure of the utility model is: a rocker push rod forming mechanism for the inner tongue of an airplane box, comprising a folding box handling module 4 and a carton buffer rack 5 for transporting the carton preliminarily folded by the pull-out folding mechanism, characterized in that the carton transported by the folding box handling module 4 is equipped with two rocker push rod forming modules 3 symmetrical about the carton handling module 4, the rocker push rod forming module 3 includes a rocker arm movable structure perpendicular to the carton handling module 4, a push rod 55 for pushing the inner tongue and a rocker arm flipping structure for folding the inner tongue are provided on the rocker arm movable structure, the rocker arm movable structure includes a rocker arm telescopic cylinder 50, and the rocker arm telescopic cylinder 50 is connected to a rocker arm mounting seat 5 1, and the rocker arm mounting seat 51 cooperates with the rocker arm telescopic slide rail 58 on the rocker arm telescopic cylinder 50, and a rocker arm telescopic positioning rod 57 for limiting the rocker arm mounting seat 51 is further provided on the platform 6, the rocker arm flip structure is installed on the rocker arm mounting seat 51, and a push rod mounting groove 56 is opened on the push rod 55, and is installed on the rocker arm mounting seat 51 by bolts. The rocker arm flip structure includes a rocker arm 53 installed on the rocker arm movable structure through a rotating shaft. The rocker arm 53 is an obtuse-angled folding block. One end of the rocker arm 53 is connected to the rocker arm flip cylinder 52 hinged on the rocker arm movable structure, and the other end of the rocker arm 53 is installed with an inner tongue hook plate 54 for folding the inner tongue by bolts.

[0016] Finish Figure 1 The box body in step bf is transported by the folding box transport module 4 and transported to the carton buffer rack 5. Then, the operation of step g is carried out. Specifically, the push rod 55 is first installed on the rocker arm mounting seat 51 through the bolt and the push rod mounting groove 56 opened thereon. Then, the rocker arm telescopic cylinder 50 drives the rocker arm mounting seat 51 to move toward the carton until it is intercepted by the rocker arm telescopic positioning rod 57. In this way, the inner tongue folding position can be accurately achieved. During the activity, the push rod 55 pushes the inner tongue into the carton. After the pushing-down process is completed, the rocker arm flip cylinder 52 is used to drive the rocker rod 53 to rotate around the rotating shaft, so that the inner tongue hook plate 54 installed thereon can be driven to rotate, and then the pushed-down inner tongue is pressed against the inner side of the left and right side plates by the inner tongue hook plate 54 to complete the folding of the left and right inner tongues. The rocker arm flip cylinder 52 is used to cooperate with the rocker rod to rotate around the rotating shaft. The maximum rotation range of the rocker rod can be controlled according to the maximum extension range of the rocker arm flip cylinder 52, ensuring that the inner tongue is folded while the left and right side plates of the paper box are not damaged due to excessive rotation range.

[0017] like Figure 2 and Figure 4 As shown, the folding box handling module 4 includes a handling movable structure and a carton handling lifting cylinder 34 on the handling movable structure. The carton handling lifting cylinder 34 is connected to a handling lifting seat. The handling lifting seat is provided with a carton handling top plate 33 and a clamping cylinder 32. The clamping cylinder 32 is connected to a carton handling clamping plate, and the carton is clamped by the carton handling top plate 33 and the carton handling clamping plate.

[0018] The folding box is transported as follows: first, the carton transport lifting cylinder 34 drives the transport lifting seat to rise and then push it against the lower bottom surface of the carton, and then the pressing cylinder 32 drives the carton transport pressing plate to cooperate with the carton transport top plate 33 to press the carton; then the transport movable structure drives the entire body to move, so that the carton enters the inner tongue folding station on the carton buffer rack 5. During the folding process, the carton transport top plate 33 and the carton transport pressing plate can clamp the folding box to prevent movement during the inner tongue folding.
