Description

Technical Field

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

[0002] A carton stitching machine is a special device used for automatic forming and binding of cartons. The feeding mechanism is used to feed the cardboard into the forming mechanism for forming. Traditional feeding mechanisms mainly use conveyor belts to transport the cardboard. In actual use, the defects of this conveyor belt feeding structure are: after leaving the conveyor belt, the cardboard relies solely on inertia to move into the forming mechanism. If the conveyor belt conveying speed is too fast, the inertia of the cardboard will be too large. After being fed into the forming component, it will collide with some components and rebound, which can easily cause damage to the cardboard and the cardboard cannot be delivered to the correct position. If the conveyor belt conveying speed is too slow, the inertia of the cardboard will be too small and it will not be able to move to the required position in the forming component. It will also cause the cardboard to be unable to be delivered to the correct position, affecting the subsequent forming quality of the carton. 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 cardboard positioning and feeding mechanism for a carton stitching machine for solving the above-mentioned problem.

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

[0005] The cardboard positioning and feeding mechanism of the carton nailing machine includes a feed conveyor belt assembly, which is characterized in that a positioning push plate is provided near the discharge end of the feed conveyor belt assembly, and the positioning push plate is connected to a movable driving assembly. When the cardboard is conveyed on the feed conveyor belt assembly, the movable driving assembly drives the positioning push plate to retract and not contact the cardboard. When the cardboard is fed out from the discharge end of the feed conveyor belt assembly, the movable driving assembly drives the positioning push plate to move, so that the positioning push plate contacts the rear end of the cardboard and slowly pushes the cardboard to a suitable position.

[0006] The feed conveyor belt assembly includes a first conveyor belt and a second conveyor belt arranged in front and behind. The first conveyor belt is provided with adsorption holes, and a negative pressure assembly that can be aligned with the adsorption holes is provided corresponding to the first conveyor belt.

[0007] 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 positioning push plate is arranged on the rotating shaft.

[0008] A plurality of positioning push plates are arranged at intervals.

[0009] The top end of the positioning push plate is provided with a bending portion.

[0010] The cardboard positioning and feeding mechanism of the carton stitching machine of the above technical solution is configured with an additional positioning push plate structure at the discharge end of the feed conveyor assembly. After the cardboard is fed out of the feed conveyor, the positioning push plate structure can be controlled to push the cardboard to the appropriate position of the forming assembly. At the same time, it also prevents the cardboard from colliding with some components and causing deformation, thereby ensuring the subsequent forming quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The utility model has the following drawings:

[0012] Figure 1 It is a structural diagram of the utility model;

[0013] Figure 2 This is a structural diagram of the positioning push plate of the utility model. DETAILED DESCRIPTION

[0014] As shown in the figure, the cardboard positioning and feeding mechanism of the nailing machine disclosed by the present invention includes a feed conveyor belt assembly, and a positioning push plate 4 is provided near the discharge end of the feed conveyor belt assembly. The positioning push plate 4 is connected to the movable driving assembly. When the cardboard is conveyed on the feed conveyor belt assembly, the movable driving assembly drives the positioning push plate 4 to retract and not contact the cardboard. When the cardboard is fed out from the discharge end of the feed conveyor belt assembly, the movable driving assembly drives the positioning push plate 4 to move, so that the positioning push plate 4 contacts the rear end of the cardboard and slowly pushes the cardboard to a suitable position.

[0015] Furthermore, the feed conveyor belt assembly includes a first conveyor belt 1 and a second conveyor belt 3 arranged in a front-to-rear manner. The first conveyor belt 1 is provided with suction holes 2, and a negative pressure assembly is provided corresponding to the first conveyor belt 1 and aligned with the suction holes 2. This structure allows the cardboard to be positioned and sucked onto the first conveyor belt 1 before being transferred to the second conveyor belt 3 for delivery, improving the stability of the cardboard conveyance on the conveyor belts.

[0016] Furthermore, the movable drive assembly includes a first cylinder 5, a piston rod of the first cylinder 5 being hinged to one end of a transmission arm 7, the other end of which is connected to a rotating shaft 6, on which the positioning push plate 4 is disposed. By controlling the first cylinder 5 to swing the transmission arm 7, and thereby rotating the transmission shaft 6, the positioning push plate 4 can be driven to swing up and down, thereby achieving the retraction and pushing operation of the positioning push plate 4.

[0017] Furthermore, a plurality of positioning push plates 4 are provided at intervals, which can push the cardboard in a more balanced manner and ensure that the cardboard will not deviate during the pushing process.

[0018] Furthermore, the top of the positioning push plate 4 is provided with a bent portion 8. This ensures that the cardboard does not warp during the pushing process, thereby ensuring the stability and reliability of the pushing operation.

[0019] The working principle of the present invention is as follows: the cardboard is first placed on the first conveyor belt 1 for conveying, and then sent to the second conveyor belt 3 and sent into the forming assembly. When most of the cardboard enters the forming assembly, the movable driving assembly drives the positioning push plate 4 to move, so that the positioning push plate 4 contacts the rear end of the cardboard and slowly pushes the cardboard to a suitable position for subsequent forming operations.

[0020] The structure of the present invention can ensure that the cardboard is accurately pushed to the appropriate position of the forming component, thereby ensuring the subsequent carton forming quality.
