[0018] The utility model is described in detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, the utility model is a positioning device for packaging bag production, including a base 1, a workbench 2 arranged on the base 1, a plurality of positioning components 3 arranged on the outside of the workbench 2 and a material sensor 4 arranged in the middle of the workbench 2, the plurality of positioning components 3 surround the workbench 2 and are arranged in a circular array with the central axis of the workbench 2, the positioning components 3 include a pressing plate 31, a driving cylinder 32 driven and connected to the pressing plate 31 and a pressing block 33 arranged on the pressing plate 31, the driving cylinder 32 drives the pressing block 33 to move up and down relative to the workbench 2 through the pressing plate 31.

[0020] During operation, the handbag is pushed and moved into the workbench 2 through an external feeding mechanism. When the material sensor 4 detects that the handbag enters the workbench 2, it will automatically send a corresponding detection signal to the control system. The control system performs a series of data analysis and processing on the detection signal, thereby sending a corresponding working signal to the driving cylinder 32, so that the driving cylinder 32 drives the pressing block 33 to move downward through the pressing plate 31. Since the pressing block 33 is made of rubber material and is installed at the end of the pressing plate 31, the pressing area of ​​the pressing block 33 on the handbag can be increased to ensure that the handbag is pressed and positioned on the workbench 2. At the same time, its rubber surface has good anti-slip performance, ensuring that there will be no positional offset or misalignment during the pressing and positioning process, and the positioning is more stable and reliable. As a preferred embodiment, four positioning components 3 are provided, and the four positioning components 3 are respectively located at the four corners of the workbench 2. The four positioning components 3 can simultaneously press and position the four corners of the handbag placed on the workbench 2, with good force uniformity, so as to achieve accurate positioning of the handbag position. The utility model plays an adjustable pressing and positioning role on the packaging bag, so that the processing position of the packaging bag remains unchanged, the positioning effect is good, and the processing quality is improved.

[0021] Both ends of the workbench 2 of this embodiment are provided with vacuum suction holes 21, and the vacuum suction holes 21 are provided with a plurality of vacuum suction holes 21 and arranged in a rectangular array. The bottom of the base 1 is provided with a vacuum generator 5, and the vacuum generator 5 is connected to the vacuum suction holes 21. Specifically, in actual use, when the external feeding mechanism pushes and moves the handbag into the workbench 2, the input end of the vacuum generator 5 is connected to the external air pump, and the output end of the vacuum generator 5 is connected to the plurality of vacuum suction holes 21, so that the plurality of vacuum suction holes 21 generate negative pressure adsorption force, thereby steadily adsorbing the back of the handbag. At the same time, the driving cylinder 32 drives the pressing block 33 to move downward relative to the workbench 2 through the pressing plate 31, and uses the pressing block 33 to press and position the front of the handbag, thereby simultaneously fixing the position of the front and back of the handbag, effectively preventing the handbag from being skewed or offset.

[0022] In this embodiment, both sides of the workbench 2 are provided with feed guide plates 22, which protrude from the workbench 2 and are used to abut against the side edges of the packaging bags carried by the workbench 2. Specifically, the feed guide plates 22 are arranged along the length direction of the workbench 2. Preferably, two feed guide plates 22 are provided and the two feed guide plates 22 protrude from both sides of the workbench 2 respectively. The side edges of the handbags can smoothly enter the workbench 2 through the directional guidance of the feed guide plates 22, and the guiding effect is good.

[0023] A limiting plate 23 is provided at one end of the workbench 2 of the present embodiment, and the limiting plate 23 is formed by protruding from the surface of the workbench 2. Specifically, the limiting plate 23 is formed by protruding from the surface of one end of the workbench 2, and when the top or bottom of the handbag is stopped and abutted against the limiting plate 23, the placement position of the handbag on the workbench 2 is effectively limited, and the limiting effect is good.

[0024] The base 1 of this embodiment is provided with mounting holes 11, and the number of the mounting holes 11 is four and the four mounting holes 11 are arranged and distributed around the base 1. Specifically, the number of the mounting holes 11 is four and the four mounting holes 11 are arranged and distributed around the base 1, and then four screws from the outside are respectively threadedly connected in the four mounting holes 11, so that the base 1 is installed and fixed on the cutting machine, and the connection is stable and reliable.
