[0017] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings and embodiments. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] like Figures 1 to 4 As shown, a clamping device for a bagging machine includes a mounting frame 1, which is cast from high-strength aluminum alloy and has excellent rigidity and lightweight properties. The structure is designed as a rectangular frame, which firmly supports the upper components while ensuring the overall stability of the device, and effectively resists vibration and external force interference during bagging operations.

[0019] Two fixing components 2 are provided above the mounting frame 1 , and the electric push rod 201 thereof is driven by a high-precision, high-thrust DC motor, with a stroke accuracy of up to ±0.1mm, which can accurately control the displacement of the clamping plate 202 .

[0020] The clamping plate 202 is a stainless steel plate with a frosted surface, is rectangular, and its area is designed according to the size of common bags. When it comes into contact with the bag, it increases friction to prevent it from slipping.

[0021] Two adjustment components 3 are provided above the mounting frame 1 .

[0022] The cylinder 301 in the adjustment component 3 is a low-friction, high-response pneumatic actuator that drives the U-shaped frame 302 to move through a fast and stable telescopic action. The U-shaped frame 302 is formed by carbon steel through a mold stamping. The U-shaped structure is an open design, which is convenient for installing and maintaining other components. The guide rod 303 mounting holes and the electric push rod 201 mounting holes are precisely machined on the two side arms to ensure that the installation positions of various components are accurate and the work together is smooth.

[0023] The two guide rods 303 fixedly connected on its outer surface adopt chrome-plated optical axes with high hardness and strong wear resistance. They slide in conjunction with the linear bearings of the fixed plate 4 with extremely small friction, ensuring the straightness and stability of the movement of the U-shaped frame 302, so that the adjustment component 3 can accurately adjust the distance between the limit component 5 and the fixed component 2, quickly adapt to bags of different widths, and improve the bagging efficiency.

[0024] Two fixing plates 4 are fixedly connected to the outer surface of the mounting frame 1. The fixing plates 4 are cut and processed from thick steel plates and have a rectangular shape. Bolt holes are provided at the four corners to firmly connect with the mounting frame 1, providing a solid support foundation for the guide rod 303 to ensure stable and reliable adjustment action.

[0025] Two limiting components 5 are provided above the mounting frame 1 .

[0026] The sliding column 501 of the limiting component 5 is made of cylindrical alloy steel with a high surface smoothness, and can slide smoothly on the inner wall of the U-shaped frame 302. The pull ring 502 fixed at one end is a round handle made of plastic, which is ergonomically designed and convenient for operators to apply force.

[0027] The second clamping plate 503 fixedly connected to the other end of the sliding column 501 is also made of stainless steel, with weight-reducing and anti-slip grooves on the surface. The shape fits the side contour of the bag and can fit the bag quickly and tightly.

[0028] The two guide columns 504 fixedly connected to the outer surface of the second clamping plate 503 are solid steel columns, which assist the second clamping plate 503 in sliding stably and ensure the accuracy of the limit.

[0029] The elastic part 505 mounted on the outer surface of the sliding column 501 is a high-strength spring. The elastic coefficient is selected through precise calculation. While providing sufficient reset elastic force, it can adapt to multiple stretching and compression cycles to ensure that the clamping plate 2 503 is quickly and accurately reset, and stable positioning is achieved on both sides of the bag to prevent the bag from shifting and shaking during bagging, thereby improving the continuity and accuracy of the bagging operation.

[0030] Working principle: Before starting the bagging operation, carefully check the stability of the mounting frame 1 to ensure that all connections are tight and not loose. At the same time, confirm that the power cords of the cylinder 301 and the electric push rod 201 are connected normally, the components are well lubricated, and there are no foreign objects obstructing the moving parts. Then, start the cylinder 301 according to the specifications of the items to be bagged. Its piston pushes the U-shaped frame 302 to move accurately and smoothly along the guide rod 303. The guide rod 303 uses a precision linear guide or a high-precision sliding sleeve design to limit the horizontal displacement of the U-shaped frame 302, driving the adjustment component 3 and the fixed component 2 to adjust the spacing to adapt to the bag width. Then, the operator pulls the pull ring 502 to overcome the elastic force of the elastic member 505 to make the sliding column 501, the clamping plate 2 503 and the guide column 504 move accordingly. After the bag is put in, release the pull ring 502. At this time, the elastic member 505 will release the elastic force to push The sliding column 501, the pull ring 502, the clamping plate 2 503 and the guide column 504 are quickly reset and moved, so that the clamping plate 2 503 can quickly press the bag between the clamping plate 1 202 and the clamping plate 2 503. Finally, the electric push rod 201 presets the parameters according to the thickness of the bag material. The electric push rod 201 is started, and its telescopic end drives the clamping plate 1 202 to slide in the U-shaped frame 302 and move close to the clamping plate 2 503. The clamping force is flexibly adjusted according to the material and thickness of the bag, such as gently clamping thin plastic bags and strongly fixing thick paper bags. It works in conjunction with the limit component 5 to keep the bag stable and accurately positioned throughout the bagging process, ensuring that the bagging operation is carried out efficiently, continuously and stably, greatly improving the quality and efficiency of bagging, and reducing production obstacles and cost losses caused by bag clamping problems.
