Description

Technical Field

[0001] This utility model relates to a bag lifting mechanism. Background Technology

[0002] In material packaging, automatic bag feeders are often used to pick up and package bags. However, existing automatic bag feeders use suction cups that are positioned in a fixed location when picking up bags. This causes the bag height to decrease after several attempts, resulting in situations where the suction cups can no longer pick up the bag. Therefore, a bag lifting mechanism is needed. Utility Model Content

[0003] The purpose of this invention is to provide a bag lifting mechanism that can raise the height of the packaging bag so that the suction cup can pick up the packaging bag.

[0004] The technical solution of this utility model is as follows: a bag lifting mechanism, including a frame, on which a lifting plate for laying packaging bags is provided, the lifting plate is slidably engaged with the frame via a guide rail slider mechanism, and a rotating shaft driven to rotate by a drive mechanism is provided on the frame, one end of a rotating crank is radially fixed on the rotating shaft, the other end of the rotating crank is hinged to one end of a swing rod, and the other end of the swing rod is hinged to the bottom surface of the lifting plate.

[0005] Furthermore, the guide rail slider mechanism includes guide rails vertically fixed on both sides of the lifting plate, and sliders fixedly connected to the frame are slidably connected to each guide rail.

[0006] Furthermore, the sliders are fixedly connected to the frame via slider fixing seats.

[0007] Furthermore, the driving mechanism is a drive motor fixed on the frame, and the output shaft of the drive motor is connected to the rotating shaft via a reducer.

[0008] Furthermore, the output shaft of the reducer is connected to the rotating shaft via a coupling.

[0009] Furthermore, the drive motor is a servo motor or a synchronous motor.

[0010] Furthermore, a hinge seat is fixed to the bottom surface of the lifting plate, and the other end of the swing rod is hinged to the hinge seat.

[0011] Furthermore, the axis of the rotating shaft and the axis of the swing rod hinged to the hinge seat are not on the same vertical plane.

[0012] Compared with the prior art, the present invention has the following advantages: the structure is simple and compact, and the height of the packaging bag can be increased so that the suction cup can pick up the packaging bag, thus avoiding the situation where the suction cup cannot pick up the packaging bag.

[0017] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0018] refer to Figures 1 to 3

[0019] A bag-lifting mechanism includes a frame with a lifting plate 10 for placing packaging bags on it. The lifting plate slides vertically with the frame via a guide rail slider mechanism. A rotating shaft 21, driven to rotate by a drive mechanism, is mounted on the frame. One end of a rotating crank 22 is radially fixed to the rotating shaft, and the other end of the crank is hinged to one end of a swing rod 23. The other end of the swing rod is hinged to the bottom surface of the lifting plate. The rotating shaft is driven to rotate by the drive mechanism, which in turn drives the rotating crank to move the swing rod, thus raising and lowering the lifting plate.

[0020] In this embodiment, in order to guide the lifting plate, the guide rail slider mechanism includes guide rails 24 vertically fixed on both sides of the lifting plate, and sliders 25 fixedly connected to the frame are slidably connected on the guide rails, so that the lifting plate can move up and down along the guide rails and sliders.

[0021] In this embodiment, the slider is fixedly connected to the frame via slider fixing seat 26, thereby realizing the connection between the slider and the frame.

[0022] In this embodiment, the driving mechanism is a drive motor 27 fixed on the frame, and the output shaft of the drive motor is connected to the rotating shaft via a reducer. Specifically, the output shaft of the reducer is connected to the rotating shaft via a coupling, thereby driving the rotating shaft to rotate. The two ends of the rotating shaft are rotatably connected to the frame via bearing seats.

[0023] In this embodiment, the drive motor is a servo motor or a synchronous motor, so as to drive the rotating shaft to achieve forward and reverse rotation.

[0024] In this embodiment, in order to achieve the hinge connection between the swing rod and the lifting plate, a hinge seat 11 is fixed on the bottom surface of the lifting plate, and the other end of the swing rod is hinged to the hinge seat.

[0025] In this embodiment, the axis of the rotating shaft and the axis of the swing rod hinged to the hinge seat are not on the same vertical plane. That is, the hinge seat is not directly above the rotating shaft. Specifically, the hinge seat can be set in the center of the bottom surface of the lifting plate, which helps to ensure the stability of the lifting.

[0026] In this embodiment, the rotating shaft and the rotating crank are integrated, and the rotating crank is located in the middle of the rotating shaft.

[0027] When the drive motor causes the rotating shaft to rotate clockwise, the crank drives the rotating shaft to push the lifting plate upward; conversely, when the rotating shaft rotates counterclockwise, it causes the lifting plate to descend. (See also...) Figure 2 and Figure 3 .

[0028] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).

[0029] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in this utility model above include states or shapes that are similar to, close to, or approximate with them.

[0030] Any component provided by this utility model can be assembled from multiple individual components, or it can be a single component manufactured by a one-piece molding process.

[0031] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
