Description

Technical Field

[0001] The utility model relates to a box nailing machine, in particular to a box pushing mechanism of the box nailing machine. Background Art

[0002] A carton stapler is a specialized machine used to form cardboard into cartons and staple the cartons together. As the cardboard is formed into the box within the forming mechanism, it is pushed by a pusher mechanism. Traditional pushers primarily consist of a conveyor belt with a pusher block mounted on it to push the box. After the pusher block pushes the box out of the forming assembly, it swings downward and back, driven by the circular conveyor belt. This downward swing can cause the pusher block to squeeze the box, causing local deformation and affecting the quality of the box. Utility Model Content

[0003] In view of the shortcomings of the background technology, the technical problem to be solved by the present invention is to provide a box pushing mechanism of a box stapling machine for solving the above problems.

[0004] To this end, the present invention is implemented by adopting the following scheme:

[0005] A box pushing mechanism of a box nailing machine includes a conveyor belt with push blocks arranged on the conveyor belt. The characteristic is that a push plate is provided at the end corresponding to the conveyor belt, and the push plate is connected to a movable drive component. When the push block on the conveyor belt swings downward driven by the conveyor belt, the movable drive component drives the push plate to move, pushing the box body to quickly separate from the push block on the conveyor belt.

[0006] The movable driving assembly includes a first cylinder, a piston rod of the first cylinder is hinged to one end of a transmission arm, the other end of the transmission arm is connected to a rotating shaft, and the push plate is arranged on the rotating shaft.

[0007] The push plate is fixed on the slider, and the slider is movably set on the rotating shaft. A first locking arm and a second locking arm are extended from the slider. The fastener passes through the through hole on the first locking arm and is screwed to the threaded hole on the second locking arm to lock the slider on the rotating shaft.

[0008] A support base is provided on the frame to rotatably support the rotating shaft.

[0009] The above technical solution is a box pushing mechanism of a box nailing machine, which is equipped with a push plate at the end of the conveyor belt. When the push block on the conveyor belt pushes the box body to be sent out and the push block swings downward and returns, the push plate will push the box body to quickly separate from the push block on the conveyor belt, that is, the push block will not contact the box body during the process of swinging back, ensuring that the box body will not be squeezed by the push block and deformed, thereby effectively ensuring the molding quality of the carton.

[0010] The utility model has the following drawings:

[0011] Figure 1 It is a structural diagram of the utility model;

[0012] Figure 2 for Figure 1 A partial enlarged view of the area pointed by A in the middle;

[0013] Figure 3 This is a structural diagram of the slider of the present utility model. DETAILED DESCRIPTION

[0014] As shown in the figure, the utility model discloses a box pushing mechanism of a box nailing machine, including a conveyor belt 1, on which push blocks 2 are arranged, and a push plate 8 is provided at the end of the corresponding conveyor belt 1. The push plate 8 is connected to a movable driving component. When the push block 2 on the conveyor belt 1 swings downward and returns under the drive of the conveyor belt, the movable driving component drives the push plate 8 to move, pushing the box body to quickly separate from the push block 2 on the conveyor belt 1.

[0015] Furthermore, the movable drive assembly includes a first cylinder 3, a piston rod of the first cylinder 3 is hinged to one end of the transmission arm 5, the other end of the transmission arm 5 is connected to the rotating shaft 6, and the push plate 8 is arranged on the rotating shaft 6. A support seat 4 is provided on the frame to provide rotational support for the rotating shaft 6 to ensure the stability of the rotation of the rotating shaft 6. By controlling the first cylinder 3 to drive the transmission arm 5 to move and the transmission rotating shaft 6 to rotate, the push plate 8 can be driven to move and push the box body to quickly separate from the push block 2 on the conveyor belt 1. Of course, in addition to adopting the above-mentioned structure, the movable drive assembly can also directly set a motor to drive the rotating shaft 6 to rotate and drive the push plate 8 to swing, or adopt common drive structures such as synchronous belt assembly, gear rack assembly, linear motor, cam structure, etc. to drive the push plate 8 to move to push the carton.

[0016] Furthermore, the push plate 8 is fixed to the slider 7, which is movably arranged on the rotating shaft 6. A first locking arm 10 and a second locking arm 12 are extended from the slider 7. A fastener passes through the through hole 9 on the first locking arm 10 and is screwed into the threaded hole 11 on the second locking arm 12, thereby locking the slider 7 to the rotating shaft 6. By adopting the above structure, the fastener can be loosened to control the movement or rotation of the slider 7 on the rotating shaft 6, and the position and angle of the push plate 8 can be adjusted, so that the push plate 8 can more adaptably push cartons of various specifications to move.

[0017] The working principle of the present invention is as follows: when the carton is formed, the forming assembly is sent out under the push of the push block 2 on the conveyor belt 1. When the 2 push blocks are about to swing downward and be sent back driven by the end of the conveyor belt 1, the movable driving assembly is actuated to drive the push plate 8 to move, pushing the rear side of the box body, giving the box body a forward driving force, so that the box body can be quickly separated from the push block 2. In this way, the push block 2 will not come into contact with the box body during the process of swinging back, ensuring that the box body will not be squeezed by the push block and deformed, thereby effectively ensuring the forming quality of the carton.
