Description

Technical Field

[0001] This invention relates to the field of folding box production equipment technology, and more specifically, to an automatic feeding mechanism for folding box sheet materials. Background Technology

[0002] As living standards gradually improve, people's requirements for packaging boxes are also increasing. Among them, folding boxes are a type of packaging box with a good texture and aesthetic appeal. Existing folding boxes generally include side panels and a outer shell, and the side panels can include square or triangular gray boards, such as... Figure 15 As shown, two triangular gray plates on the same side are combined to form a square structure and are located on the left and right sides of the square gray plate.

[0003] Current folding box manufacturing processes typically involve manual feeding of square gray boards, first triangular gray boards, and second triangular gray boards. However, this method is extremely inefficient and consumes a large amount of manpower. With technological advancements, some board feeding mechanisms have begun to appear on the market. These mechanisms can replace manual labor to automate board feeding. However, existing board feeding mechanisms have the following shortcomings:

[0004] 1. Existing sheet material feeding mechanisms generally suffer from poor stability and versatility, which can easily lead to sheet material falling and machine stoppage. They are also difficult to be compatible with sheets of different specifications, require long setup times, and demand high levels of professional skills, which is not conducive to improving work efficiency.

[0005] 2. Generally, it can only be used for feeding square boards or triangular boards. The two types of boards require two different machines, which results in high operating costs, large footprint, and low board feeding speed, affecting production efficiency.

[0006] 3. The existing triangular plate feeding mechanism lacks the triangular plate position correction function, which is not conducive to triangular plate assembly. Summary of the Invention

[0056] like Figure 8 As shown, each of the two triangular plate positioning devices 6 can include a positioning platform 61, a positioning push plate cylinder 62, a push block 63, and a middle positioning partition 64. The adjacent two sides of the positioning platform 61 are respectively provided with mutually perpendicular side positioning baffles 611. The middle positioning partition 64 is installed on the positioning platform 61 and located between the two side positioning baffles 611. The middle positioning partition 64 and the two side positioning baffles 611 form a 45-degree angle, thereby forming two triangular positioning areas on each positioning platform 61. There are two positioning push plate cylinders 62 and they are located in the two positioning areas of the positioning platform 61. The extension and retraction parts of the positioning push plate cylinders 62 are connected to the push block 63 and can drive the push block 63 to push the triangular plate.

[0057] When the triangle plate suction device 5 places the triangle plate in the positioning area on the positioning platform 61, the positioning push plate cylinder 62 drives the push block 63 to move. The push block 63 pushes one right-angled side of the triangle plate, so that the triangle plate can be positioned and corrected between the middle positioning partition 64 and the side positioning baffle 611.

The width-adjusting device 10 is connected to the rear end of the two bottom carrier plate profiles 83 of the two triangular plate hoppers 2 and the square plate hopper 8 respectively. The width-adjusting device 10 can drive the two triangular plate hoppers 2 to move away from each other and closer to each other in the horizontal direction, and drive the two bottom carrier plate profiles 83 of the square plate hopper 8 to move away from each other and closer to each other in the horizontal direction.

The two corresponding triangular plate hoppers 2 are connected to the bottom of the transmission. The two threaded sections of the positive and negative screws 107 are respectively connected to the rear ends of the two corresponding bottom carrier plates 83 through the screw nut seat 108. The width adjustment gear 104 is installed on the shaft of the handwheel 101. The width adjustment gear 205 is installed at one end of the positive and negative screws 102. The width adjustment gear 309 is installed at one end of the positive and negative screws 107. The width adjustment chain 106 meshes with the width adjustment gear 104, the width adjustment gear 205 and the width adjustment gear 309 respectively.

[0063] Turning the handwheel 101 synchronously drives the first and second lead screws 102 and 107 to rotate, thereby adjusting the distance between the two triangular plate hoppers 2 and the width of the square plate hopper 8. Of course, depending on actual needs, the handwheel can be replaced with other electric drive devices, such as a motor.

[0064] In this embodiment, the automatic feeding mechanism for folding box panels is equipped with a width adjustment function, which can adapt to square panels of different widths and has good versatility.

[0065] The working principle of the automatic feeding mechanism for folding box panels in this embodiment is as follows:

[0066] First, the operator can place the triangular plates on the two triangular plate hoppers 2 and the square plates on the square plate hopper 8, respectively. The machine is then started. The two triangular plate suction devices 5 pick up the triangular plates from the two triangular plate hoppers 2, and, driven by the primary translation drive device 4, place the triangular plates on the two triangular plate positioning devices for position correction and positioning. Then, the primary translation drive device 4 drives the triangular plate suction device 5 back to its original position. The secondary translation drive device 7 drives the triangular plate positioning device 6 and the triangular plates to move horizontally to the rear end, simultaneously driving the square plate translation push device 9 to push the square plates in the square plate hopper 8 horizontally to the rear end, until the triangular plates and square plates are synchronously aligned and moved to the designated positions. At this point, the triangular plates are located on the left and right sides of the square plates. Subsequently, the secondary translation drive device 7 drives the triangular plate positioning device 6 and the square plate translation push device 9 back to their original positions, and this cycle repeats.

Based on the above embodiment 1, this embodiment 2 can also be provided with a robotic arm board picking device 12 for picking up the square plates pushed by the triangular plate positioning device and the square plate pushed by the square plate translation and pushing device together to a designated position. The robotic arm board picking device 12 can be installed on the board output side (i.e., the rear end) of the frame 1.

[0069] like Figure 14 As shown, the robotic arm plate-picking device 12 may include a multi-axis robotic arm 121, a suction cup mounting frame 2 122, and several plate-picking suction cups 123. The end of the multi-axis robotic arm 121 is connected to the suction cup mounting frame 2 122, and the plate-picking suction cups 123 are mounted on the suction cup mounting frame 2 122.

[0070] Driven by the multi-axis robot 121, the plate-retrieving suction cup 123 can simultaneously pick up the triangular plate and the square plate that have been moved to the designated position at the rear end of the frame.

[0071] In summary, the present invention has a reasonable structural layout, which can realize automatic feeding and automatic position correction and positioning of triangular plates, as well as automatic feeding of square plates on a single machine.
