[0024] refer to Figure 1 and Figure 3 The driving assembly 9 includes a dual-axis motor 91, which is fixedly connected to the inside of the groove 8. The output end of the dual-axis motor 91 is fixedly connected to a transmission rod 92, and the outer side of the transmission rod 92 is fixedly connected to a first bevel tooth 93. The top of the first bevel tooth 93 is meshingly connected to a second bevel tooth 94, and the top of the second bevel tooth 94 is fixedly connected to the bottom of the screw 6.

[0025] As a technical optimization scheme of the utility model, by setting up the driving component 9, the dual-axis motor 91 can effectively drive the transmission rod 92 to rotate, and the transmission rod 92 drives the first bevel gear 93 to rotate, and then the first bevel gear 93 drives the second bevel gear 94 screw 6 to rotate, so that the rotation of the screw 6 drives the adjustment block 7 to move the rotating plate 2 upward, thereby achieving the effect of easy adjustment.

[0026] refer to Figure 1 and Figure 4 The binding assembly 10 includes a mounting seat 101, which is fixedly connected to the front side of the top right side of the base 1. The top of the mounting seat 101 is movably connected to a rotating rod 102 through an axle pin, and the surface of the rotating rod 102 is movably connected to a rope drum 103.

[0027] As a technical optimization solution of the utility model, by setting up a binding component 10, the user pulls the rope drum 103 to rotate, so that the rope drum 103 rotates through the rotating rod 102, and then pulls out the rope on the surface of the rope drum 103, so that the user can easily bind the packaging bag through the rope, thereby improving the packaging effect of the packaging bag.

[0028] refer to Figure 1 and Figure 3 A bearing seat 11 is sleeved on the surface of the transmission rod 92 , and the bearing seat 11 is fixedly installed on both sides of the inner wall of the groove 8 .

[0029] As a technical optimization solution of the present invention, by providing the bearing seat 11, the bearing seat 11 can effectively provide auxiliary support to the transmission rod 92, thereby improving the stability of the transmission rod 92 and avoiding shaking when the transmission rod 92 rotates.

The baffle 16 can block the groove 8 to prevent materials and impurities from entering the interior of the groove 8, making it difficult for the user to clean.

[0036] The working principle and use process of the utility model are as follows: when in use, the user first puts the packaging bag on the surface of the opening seat 3, and then the user starts the dual-axis motor 91 to drive the transmission rod 92 to rotate, and the transmission rod 92 drives the first bevel gear 93 to rotate, and then the first bevel gear 93 drives the second bevel gear 94 screw 6 to rotate, so that the screw 6 rotates to drive the adjustment block 7 to move the rotating plate 2 upward, so as to achieve the effect of easy adjustment, so that the opening seat 3 can open the packaging bags of different lengths, and then the inner side of the rotating plate 2 can be placed on the packaging bags of different sizes, so that the opening seat 3 can open the packaging bags of different sizes, avoiding the packaging bag size The longer length makes it impossible for the opening seat 3 to open the packaging bag, thereby improving the flexibility of the opening seat 3, and then the packaging bag is rotated by the opening seat 3, and then the material is added into the packaging bag. When the material inside the packaging bag is full, the user rotates the rope drum 103 by pulling the rope drum 103, so that the rope drum 103 rotates through the rotating rod 102, and then the rope on the surface of the rope drum 103 is pulled out, and the rope is used to bundle the packaging bag, thereby improving the packaging effect of the packaging bag, and then the rope is put into the cutting board 12, and the user presses the cutting knife 13 to cut the rope, so that the user can bundle the packaging bag and improve the packaging efficiency of the packaging bag.

[0037] To sum up: this valve bag opening device, by setting an adjusting plate 5, a screw 6, an adjusting block 7 and a driving assembly 9, can effectively enable the driving assembly 9 to drive the screw 6 inside the adjusting plate 5 to rotate, and drive the adjusting block 7 to move upward through the screw 6, so that the adjusting block 7 can adjust the rotating plate 2 to the required height, thereby solving the problem that although the device is convenient for opening the packaging bag, it lacks a height adjustment function. Due to the various sizes of packaging bags, the existing opening device can only adapt to packaging bags of a specific size and cannot be adjusted accordingly according to the length of different packaging bags, so its scope of use is limited.
