[0015] In the description of the utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc., should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable 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 internal communication between two components; a fixed connection can be welding or gluing. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0016] like Figure 1 、 Figure 2 The illustrated edge strip cutting structure includes a connecting shaft 1, which is connected to a bag making machine. A first connecting block 2 and a second connecting block 7 are connected to the connecting shaft 1. Fastening bolts are provided on the first and second connecting blocks 2 and 7 to maintain their positions on the connecting shaft 1. A blade 4 is connected to the first connecting block 2, and a limiting block 5 is connected to the second connecting block 7. The limiting block is L-shaped, with one end of the limiting block 5 connected to the second connecting block 7. The connection is provided with multiple limiting grooves, and the limiting block 5 is fixedly connected to the second connecting block 7 by fixing bolts. The height of the limiting block 5 can be adjusted, and a separation groove 13 is provided at the other end. The separation groove 13 is provided near the edge of the first connecting block 2. When a packaging bag passes through, the portion to be cut is inserted into the separation groove 13. A limiting hole 6 is provided on one side of the separation groove 13. The end of the blade 4 enters the limiting hole 6, and the blade 4 cuts the edge strip in the separation groove 13. The other side of the separation groove 13 can prevent the blade 4 from cutting through the packaging bag.

[0017] A third connecting block 8 and a fourth connecting block 11 are provided on the connecting shaft 1, and the fourth connecting block 11 is connected to a motor 10, which is connected to a screw rod 9. The screw rod 9 passes through the third connecting block 8 and is connected to the first connecting block 2. The motor drives the screw rod to rotate, so that the first connecting block 2 can drive the blade 4 to move precisely.

[0018] The blade 4 is connected to the first connecting block 2 through a rotating shaft. A clamping block 3 is set on one side of the blade 4. The clamping block 3 is connected to the first connecting block 2 through bolts to clamp the blade 4 between the clamping block 3 and the first connecting block 2. The cutting angle of the blade 4 can be adjusted, and the cutting depth can be adjusted according to the thickness of the packaging bag.

[0019] An infrared probe is provided on the first connecting block 2, and the infrared probe faces the second connecting block 7. The infrared probe can accurately measure the distance between the first connecting block 2 and the second connecting block 7, and the motor rotation is controlled by the PC to accurately control the position of the first connecting block 2 and the blade 4.

[0020] A rotating plate is connected to the limiting hole 6 by bolts, and a pressure block 12 is connected to one end of the rotating plate. The pressure block 12 is a roller. The pressure block 12 is set in the separation groove 13. The pressure block 12 is on the side close to the packaging bag body. It uses its own weight to press the non-separated part of the edge strip into the separation groove 13 to prevent the edge strip from jumping or moving due to vibration, thereby ensuring that the cutting is flush.

[0021] The structural design of the utility model is reasonable and ingenious. The part of the packaging bag that needs to be trimmed is stuck in the separation groove, and the blade passes through the limiting hole to cut the edge strip. The part of the edge strip that is not separated from the bag body is pressed by the pressing block, and the motor drives the screw rod to rotate to accurately adjust the position of the cutter.

[0022] The above description is based on the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification. Its technical scope must be determined according to the scope of the claims.
