Description

Technical Field

[0001] The utility model relates to the technical field of valve bags, in particular to a valve bag production cutting mechanism. Background Art

[0002] Valve bags, commonly known as paste-bottom bags, are currently popular international packaging bags. They are fed from the top or bottom valve port and use special filling equipment. After filling the materials, they are packed into cubes. The bags are neatly stacked and beautiful, and are environmentally friendly bags.

[0003] However, in the prior art, there is a lack of corresponding auxiliary fixing mechanism when cutting the integrated valve bag, which causes the valve bag to be dragged easily during cutting, affecting the cutting quality. Moreover, as the working time goes by, debris is easily stuck to the cutting tool, which is not conducive to the cutting of the valve bag. Therefore, we propose a valve bag production cutting mechanism. Utility Model Content

[0004] The utility model provides a valve bag production cutting mechanism, which solves the above-mentioned technical problems.

[0005] The utility model solves the above-mentioned technical problems with the following solution: a valve bag production cutting mechanism, comprising an inverted L-shaped fixing frame, a connecting plate is horizontally arranged below the fixing frame, the fixing frame is connected to the connecting plate through a lifting control mechanism, a cutting tool is vertically fixedly installed in the middle of the lower end surface of the connecting plate, and both ends of the lower end surface of the connecting plate are respectively fixedly installed with a horizontally arranged pressure plate through a vertically arranged first telescopic rod, a spring is movably sleeved on the outer side wall of the first telescopic rod, an installation frame is horizontally arranged below the cutting tool, the installation frame is fixedly connected to the side wall of the fixing frame, and cleaning soft brushes are respectively fixedly installed on the inner side walls on both sides of the installation frame.

[0006] Preferably, the lifting control mechanism comprises an electric push rod vertically fixedly mounted on the upper end surface of the fixing frame, the free end of the electric push rod movably passes through the fixing frame, and the free end of the electric push rod is fixedly connected to the upper end surface of the connecting plate.

[0007] Preferably, a second telescopic rod is fixedly mounted on the corner of the upper end surface of the connecting plate, and the second telescopic rod is fixedly connected to the upper end and the fixing frame.

[0008] Preferably, a soft pad is laterally fixedly mounted on the lower end surface of the pressing plate, and the soft pad is made of rubber material.

[0009] Preferably, the inner length of the installation frame matches the cutting tool, and the two cleaning soft brushes are in contact with each other.

[0010] The beneficial effects of the utility model are:

[0011] 1. The electric push rod is set to indirectly drive the cutting tool to move up and down to achieve the cutting of the valve bag. When the electric push rod is extended, the pressure plate is indirectly driven to move downward through the transmission of the connecting plate. The soft cushion on the bottom of the pressure plate contacts the valve bag, and the spring squeezes the pressure plate, so that the pressure plate squeezes and fixes the valve bag, providing a stable cutting environment for the cutting tool to ensure the cutting quality;

[0012] 2. By setting up an installation frame, a cleaning soft brush is set and installed in the installation frame. When the cutting tool moves downward for cutting or resets and moves upward, it can pass between two cleaning soft brushes. The cleaning soft brush is used to automatically clean the cutting tool to remove debris on the surface of the cutting tool, which is convenient for subsequent cutting.

[0021] Example 1

[0022] like Figure 1-3 As shown, the utility model is a valve bag production cutting mechanism, including an inverted L-shaped fixing frame 1, a connecting plate 2 is horizontally arranged below the fixing frame 1, a second telescopic rod 10 is fixedly installed at the corner of the upper end surface of the connecting plate 2, the second telescopic rod 10 is fixedly connected to the upper end and the fixing frame 1, and the second telescopic rod 10 is arranged to connect the connecting plate 2 and the fixing frame 1, so that the up and down movement of the connecting plate 2 is more stable, and the cutting quality is improved. The fixing frame 1 is connected to the connecting plate 2 through a lifting control mechanism, a cutting tool 3 is vertically fixedly installed in the middle of the lower end surface of the connecting plate 2, and a horizontally arranged pressing plate 4 is fixedly installed at both ends of the lower end surface of the connecting plate 2 through a vertically arranged first telescopic rod 5, and a soft pad 11 is horizontally fixedly installed on the lower end surface of the pressing plate 4. The soft pad 11 is made of rubber material and a soft pad is arranged. 11 provides the fit between the pressure plate 4 and the valve bag, so that the device can fix the valve mouth belt more stably. The outer wall of the first telescopic rod 5 is movably sleeved with a spring 6. A mounting frame 7 is horizontally arranged below the cutting tool 3. The inner length of the mounting frame 7 matches the cutting tool 3. Two cleaning soft brushes 8 are in contact with each other. The mounting frame 7 is fixedly connected to the side wall of the fixing frame 1. Cleaning soft brushes 8 are fixedly installed on the inner walls on both sides of the mounting frame 7. The device can drive the pressure plate 4 to move while driving the cutting tool 3 to cut by setting an electric push rod. The valve bag is squeezed and fixed by the pressure plate 4, which makes the cutting more stable and prevents dragging. In the process of the cutting tool 3 moving up and down, the cleaning soft brush 8 can be used to automatically clean the cutting tool 3 to reduce the adhesion of debris and facilitate subsequent cutting work.

[0023] Example 2

[0024] like Figure 1-3 As shown, the lifting control mechanism includes an electric push rod 9 vertically fixedly installed on the upper end surface of the fixing frame 1, the free end of the electric push rod 9 movably penetrates the fixing frame 1, and the free end of the electric push rod 9 is fixedly connected to the upper end surface of the connecting plate 2. The extension of the electric push rod 9 can drive the cutting tool 3 and the pressure plate 4 to move downward, thereby fixing the valve bag and ensuring that the cutting tool 3 can pass between two cleaning soft brushes 8 to achieve automatic cleaning of the cutting tool 3.

[0025] Working principle:

[0026] When in use, the conveyor belt transporting the valve bag stops moving, and then the electric push rod 9 extends to drive the connecting plate 2 to move downward, and the cutting tool 3 and the pressing plate 4 under the connecting plate 2 move downward synchronously, and the soft pad 11 on the lower surface of the pressing plate 4 first abuts against the valve bag below to squeeze and fix the valve bag, and at the same time the cutting tool 3 passes through the cleaning soft brush 8, and then the cutting tool 3 contacts the valve bag for cutting, and then the electric push rod 9 shortens, driving the cutting tool 3 and other components to reset to the initial position.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above.
