[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to specific embodiments of this application and the accompanying drawings.

[0036] like Figures 1-5 As shown, a food packaging bag directional conveying device includes: a frame 1, on which a conveying component 2 is provided, and above the conveying component 2, in the order of material conveying direction, a feeding component 3, a vision inspection component 4, a defective product rejection component 5 and a collection component 6 are arranged sequentially. The conveying component 2 includes: a negative pressure conveyor belt 201, a drive roller 202 and a vacuum plate 203.

[0037] The feeding assembly 3 includes: a first mounting frame 301 fixedly connected to the frame 1, a storage box 302 fixedly connected to the first mounting frame 301, a discharge port 311 at the lower part of the storage box 302, clearance grooves 307 on a pair of opposite vertical sidewalls of the storage box 302, and antistatic brushes 306 vertically arranged on the outer side of the vertical sidewalls, with the working ends of the antistatic brushes 306 extending into the inner cavity of the storage box 302 through the clearance grooves 307.

[0038] Static electricity is easily generated during the production and storage of food packaging bags. This static electricity can cause the bags to attract and stick together, affecting the smoothness of the discharge and potentially interfering with subsequent visual inspection and conveying processes. The working end of the anti-static brush 306 extends into the inner cavity of the storage box through the clearance groove 307, which can eliminate static electricity on the surface of the packaging bags in time before they are discharged, ensuring that the packaging bags can be smoothly output from the discharge port 311. This avoids feeding problems and equipment failures caused by static electricity, improving the efficiency and stability of the feeding process.

[0039] Furthermore, the brush provides a certain clamping force to the stacked packaging bags, preventing the upper adjacent packaging bags from moving and bending as the bottom packaging bag is pulled away by the negative pressure conveyor belt 201, thereby avoiding misjudgment by the visual inspection component 4 and reducing the misjudgment rate.

[0040] like Figures 4-5 As shown, the inner cavity of the storage box 302 is provided with a baffle 308 that cooperates with the discharge port 311. The front and rear sides of the baffle 308 are respectively threaded with adjustment knobs 309. The side wall of the storage box 302 is provided with an adjustment groove 310 for cooperating with the adjustment knobs 309.

[0041] The adjustment knob 309 cooperates with the adjustment groove 310 to adjust the height and tilt angle of the baffle 308.

[0042] Different specifications of food packaging bags require different discharge space and conditions when discharging. By adjusting the height and inclination angle of the baffle 308, the shape and size of the discharge port 311 can be fine-tuned, so as to better adapt to the discharge requirements of packaging bags of different specifications.

[0043] As shown in Figure 5 , the lower end of the baffle 308 is provided with a circular arc segment for guiding the material. The contact between the circular arc segment and the packaging bag is a relatively smooth transition, which can reduce the risk of wear on the surface of the packaging bag and ensure the integrity and appearance quality of the packaging bag.

[0044] As shown in Figure 4 , one side of the storage box 302 is open, and a side cover plate 303 is arranged at the opening. The lower end of the side cover plate 303 is rotationally connected to the storage box 302, and the upper end is rotationally connected to a buckle 304. The buckle 304 is provided with a clamping groove, and the storage box 302 is provided with a clamping rod 305 matched with the clamping groove.

[0045] The buckle 304 and the clamping rod 305 cooperate to fix the side cover plate 303.

[0046] The storage box 302 is open on one side and is provided with a side cover plate 303 that can be opened and closed. When it is necessary to supplement food packaging bags in the storage box 302, the operator only needs to open the side cover plate 303, and then the packaging bag can be easily put into the storage box. Compared with some designs that require complex operations or disassembly of part of the structure to add materials, this side opening type is more intuitive and convenient, saves the time for adding materials, and improves the efficiency.

[0047] As shown in Figure 6 , the visual detection assembly 4 comprises a second mounting bracket 401 fixedly connected with the rack 1. The inner cavity of the second mounting bracket 401 is open at the lower part, and a camera 402 is fixedly connected to the upper part of the inner cavity of the second mounting bracket 401. A plurality of light supplement lamp strips 403 are arranged on the side wall of the inner cavity of the second mounting bracket 401. The arrangement of the light supplement lamp strips 403 on the side wall of the inner cavity of the second mounting bracket 401 can provide sufficient light for the detection area. Sufficient light can improve the clarity and brightness of the images taken by the camera 402, and the details in the images are more obvious. Especially for some packaging bags with deep color or surface reflection, the light supplement lamp strips 403 can effectively improve the image quality, and ensure that the visual detection system can accurately identify the information such as text, patterns and defects on the packaging bag.

[0048] As shown in Figure 2As shown, the transmission roller 202 is matched with an encoder 205. The encoder 205 can accurately measure the rotation angle and the number of turns of the transmission roller 202. Since the transmission roller is connected with the conveying belt, the conveying belt drives the food packaging bag to move, and the rotation information of the transmission roller 202 is acquired through the encoder 205, so that the position of the defective packaging bag in the conveying process detected by the visual detection assembly 4 can be accurately calculated, facilitating the subsequent rejection action.

[0049] As shown in the figure, Figures 7-8 The defective product rejection assembly 5 includes a lead screw moving assembly 501 fixedly connected with the rack 1, a third mounting bracket 502 arranged on the lead screw moving assembly 501, a telescopic rod 503 fixedly connected with the third mounting bracket 502, a suction nozzle plate 504 fixedly connected with the lower end of the telescopic rod 503, and a waste box 505 arranged on one side of the rack 1.

[0050] The defective product rejection assembly 5 is based on the defective product information marked by the visual detection assembly 4 and the position acquired by the encoder 205. When the defective product moves below the suction nozzle plate 504, the telescopic rod 503 acts so that the defective product contacts the suction nozzle plate 504 and is separated from the surface of the negative pressure conveying belt 201. The lead screw moving assembly 501 acts so that the suction nozzle plate 504 moves above the waste box 505. The negative pressure of the suction nozzle plate 504 is released, so that the defective product falls into the waste box 505, and one defective product rejection action is completed.

[0051] As shown in the figure, Figure 7 The collection assembly 6 includes a guide plate 601 matched with the negative pressure conveying belt 201, and a good product box 602 arranged at the end of the guide plate 601 away from the negative pressure conveying belt 201.

[0052] In a specific embodiment, the vacuum plate 203 is provided with a connecting head 204 matched with an external negative pressure generator, so that the negative pressure conveying belt 201 can adsorb the packaging bag on the surface. However, the negative pressure at the transmission roller 202 is weak. The guide plate 601 is matched with the part of the negative pressure conveying belt 201 to peel the good product packaging bag from the conveying belt and make it fall into the good product box.

[0053] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled persons in the art, without departing from the creative concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application.
