[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figure 1-3 As shown, the present invention proposes a food packaging paper positioning and cutting device, including a processing table 1, conveyor belts 2 on both the front and rear sides of the top of the processing table 1, a gantry frame 3 located between the two conveyor belts 2 on the top of the processing table 1, a hydraulic cylinder 5 on the top of the gantry frame 3, a lifting plate 6 on the output end of the hydraulic cylinder 5, a cutting component at the bottom of the lifting plate 6, and two positioning components 9 located on the front and rear sides of the cutting component respectively at the bottom of the lifting plate 6.

[0024] It is worth mentioning that the side wall of the processing table 1 is equipped with a control panel, the conveyor belt 2 adopts the existing belt conveyor, and the bottom of the lifting plate 6 is equipped with a laser range sensor 11 (model can be HG-C1200). The laser range sensor 11, the conveyor belt 2 and the hydraulic cylinder 5 are all electrically connected to the control panel.

[0025] The positioning component 9 includes a positioning plate 93. Two sets of telescopic components are connected between the positioning plate 93 and the lifting plate 6. The top of the positioning plate 93 has two placement slots 931, and multiple stacked lead sheets 10 are placed inside the placement slots 931.

[0026] It should be noted that by setting positioning components 9 on both sides of the cutter, the food packaging paper can be accurately positioned to ensure the accuracy of the cutting position and improve the cutting quality. The number of lead sheets 10 can be increased or decreased to adjust the weight of the positioning pressure plate 93 according to the thickness of the packaging paper, thereby improving applicability. Thicker packaging paper requires greater pressure to ensure stability during cutting, while thinner packaging paper requires less pressure to avoid excessive pressure damage.

[0027] Please see Figure 2 In this embodiment, the telescopic component includes a support frame 91, which is fixedly connected to the bottom of the lifting plate 6. A telescopic rod 92 is provided on the inner bottom wall of the support frame 91. The fixed end of the telescopic rod 92 is fixedly connected to the bottom of the lifting plate 6, and the telescopic end of the telescopic rod 92 moves through the support frame 91 and is fixedly connected to the positioning pressure plate 93.

[0028] It should be noted that the positioning plate 93 is located at a height lower than the height of the cutting blade 8 in the initial state before cutting, so that the positioning plate 93 will contact and press the packaging paper first during the cutting and descent process of the cutting blade 8.

[0029] The positioning plate 93 has two notches 932 on both its front and rear side walls, and the notches 932 are connected to the placement groove 931.

[0030] The notch 932 connects to the placement groove 931, allowing fingers to easily reach into the notch 932 to pinch the lead sheet 10 inside the placement groove 931 and remove it.

[0031] In this embodiment, the cutting component includes a mounting base 7, which is fixedly connected to the bottom of the lifting plate 6. A cutting blade 8 is provided at the bottom of the mounting base 7, and a cutting plate 4 is provided at the center of the top of the processing table 1. The cutting plate 4 corresponds to the position of the cutting blade 8.

[0032] It is worth mentioning that the cutting blade 8 is located in the gap between the two positioning plates 93. Therefore, during the cutting process, the two positioning plates 93 will press down on both sides of the cutting position of the packaging paper, thereby achieving the effect of positioning and fixing.

[0033] The positioning plate 93 has rounded edges on both the front and rear sides, and the length of the positioning plate 93 is greater than the length of the cutting blade 8.

[0034] Working principle: The packaging paper to be cut is conveyed by the conveyor belt 2 on one side. When the packaging paper is conveyed to the cutting plate 4, the distance moved by the packaging paper is monitored by the laser range sensor 11. When the laser range sensor 11 detects that the packaging paper has moved to the set distance, it transmits a signal to the control panel. At this time, the control panel controls the conveyor belt 2 to stop working and controls the hydraulic cylinder 5 to push the lifting plate 6 down. During the downward movement, the two positioning pressure plates 93 will first contact and press the packaging paper. As the downward movement continues, the cutting blade 8 will cut the positioned packaging paper. Then, the cut packaging paper is conveyed away by the conveyor belt 2 on the other side.

[0035] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
