[0029] As Figure 1 、 Figure 3 、 Figure 5 shown, the present utility model provides an automatic bag clamping machine for feeding, which includes an unpacking machine main body 1 and a feeding channel 9 connected to the unpacking machine main body 1. An inner conveyor belt 2 at the same horizontal level as the feeding channel 9 is provided inside the unpacking machine main body 1. A cutting assembly 3 is provided above the inner conveyor belt 2. The cutting assembly 3 includes a movable adjustment assembly 301 and a cutter assembly 302. The adjustment assembly 301 and the cutter assembly 302 are symmetrically arranged on both sides of the inner conveyor belt 2. The cutter assembly 302 includes a cutter 3021 and a cutting motor 3022. The cutter 3021 is placed at one end of the adjustment assembly 301 away from the feeding channel 9. The material bag 10 is placed on the outer conveyor belt surface of the feeding channel 9 and transported into the unpacking machine main body 1. The end of the inner conveyor belt 2 is connected to a bag outlet channel 4. The end of the bag outlet channel 4 is successively connected to a residual bag channel 5 and a residual material recovery channel 6. The end of the residual material recovery channel 6 is connected to a collection hopper 7.

[0030] As Figure 1 、 Figure 2 、 Figure 6 shown, there are two groups of adjustment assemblies 301. Each group of adjustment assemblies 301 includes a floating baffle 3011 arranged along the movement direction of the inner conveyor belt 2. A bent section is provided on the side of the floating baffle 3011 close to the feeding channel 9 to increase the distance between the two floating baffles 3011. The material bag 10 deviated from the inner conveyor belt 2 can move along the floating baffle 3011 onto the inner conveyor belt 2, reducing machine jams caused by deviation and improving the service life of the machine. A proximity switch 3012 is provided at the center position of the floating baffle 3011. Adjustment cylinders 3013 are provided on both sides of the proximity switch 3012. The adjustment cylinders 3013 are three-axis cylinders. Cylinder brackets are provided at the bottoms of the adjustment cylinders 3013. The cylinder brackets are fixedly connected to the inner side wall of the unpacking machine main body 1. The cylinder brackets can provide stable support for the adjustment cylinders 3013. The two groups of cylinder brackets together can provide support to make the floating baffle 3011 more stable. The two adjustment cylinders 3013 can expand and contract to drive the floating baffle 3011 to move back and forth. The two floating baffles 3011 move together to clamp and position material packaging bags of different sizes.

[0031] As Figure 1 、 Figure 2 、 Figure 4As shown in the figure, the cutter assembly 302 includes a cutter 3021, a cutting motor 3022, and a cutter fixing arm 3023. The cutter 3021 is placed at one end of the adjustment assembly 301 away from the feeding channel 9. There is a groove on the lower side near the cutter 3021 of the floating baffle 3011. The cutter 3021 is placed between the groove and the inner conveyor belt 2 and does not contact either of them. In this way, the length of the floating baffle 3011 can be extended as much as possible, the adjustment range of the floating baffle 3011 for the material bag 10 can be increased, the stability can be improved, and it is convenient for the cutter 3021 to cut the material bag 10. The cutting motor 3022 is arranged above the shell of the unpacking machine main body 1. The output end of the cutting motor 3022 penetrates through the shell of the unpacking machine main body 1 and is connected to the fixing arm 3023 through a coupling. Through the power transmission of the cutter fixing arm 3023, it is ensured that the position of the cutter 3021 can be adjusted arbitrarily and is not restricted by the cutting motor 3022. At the same time, the cutting motor 3022 is stably placed outside the unpacking machine main body, which can ensure its stable operation and avoid the heat or vibration generated from affecting the unpacking environment, thereby improving the quality of the unpacked materials.

[0032] There are two pulleys connected by a belt inside the shell of the cutter fixing arm 3023. One of the pulleys is coaxially connected to the cutter 3021 and the cutter 3021 is arranged below the fixing arm 3023. The pulley at the other end of the fixing arm 3023 is coaxially connected to the cutting motor 3022. The cutting motor 3022 is arranged above the shell of the unpacking machine main body 1. The power of the cutting motor 3022 is transmitted to the cutter 3011 through the belt to drive 3011 to rotate and cut the material bag 10 on the inner conveyor belt 2.

[0033] There is an adjusting rod on the upper surface of the fixing arm 3023. The cutting assembly 301 further includes a cutter adjustment cylinder 3024. The output end of the cutter adjustment cylinder 3024 is connected to the side of the adjusting rod at the top of the cutter fixing arm 3023. Through the telescoping of the cutter adjustment cylinder 3024, the adjusting rod can be driven to move, and at the same time, the fixing arm 3023 can be driven to rotate along the motor shaft to complete the adjustment of the position of the cutter 3021 to adapt to material bags 10 of different sizes and ensure accurate cutting of them.

[0034] When the utility model is in use, the material bag 10 is placed on the surface of the outer conveyor belt of the feeding channel 9 manually, by a gantry crane or a forklift. The outer conveyor belt transports the material bag 9 to the inside of the unpacking machine main body 1, and the inner conveyor belt 2 continues to transport the material bag 9 forward. After passing through the cutting assembly 3, two proximity switches 3012 detect the size of the material bag 9 and send signals to start the adjustment cylinder 3013 to adjust the position of the floating baffle 3011, so as to clamp and position material bags 10 of different sizes. Then, start the cutter adjustment cylinder 3024 to push the cutter fixing arm 3023 to rotate, and adjust the cutter 3021 to the accurate position to complete the cutting and unpacking of the material bag 9. The unpacked material bag 9 enters the waste bag channel 5 through the bag outlet channel 4. The material bag 9 is fully rotated in the waste bag channel 5 and then pushed out. The material in the material bag 9 falls into the waste material recovery channel 6, and the waste material recovery channel 6 rotates the waste material to the collection hopper 7.
