[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] Please see Figures 1 to 3 A pressing device for a bag making machine includes a base 2. A horizontal groove 11 is provided on the surface of the base 2. Two sliders 10 are slidably connected inside the horizontal groove 11 to facilitate the sliding of the sliders 10 inside the horizontal groove 11 and improve the stability of movement. A connecting plate 5 is fixedly connected to the surface of each slider 10. A slot 3 is provided on the surface of the base 2. A drive assembly for pressing film in the bag making machine is provided inside the slot 3. A connecting assembly is provided above the drive assembly. A fixing post 8 is fixedly connected to the top of each slider 10. An opening 19 is provided on the surface of each fixing post 8. A first pressing roller 6 is rotatably connected to the inner sidewall of each opening 19. A through groove 16 is provided through the inner sidewall of each opening 19.

[0022] Vertical rods 20 are fixedly connected to the inner walls of the two through slots 16. Movable blocks are fitted on the outside of the two vertical rods 20. A second pressing roller 7 is rotatably connected to one end of each of the two movable blocks. The movable blocks slide outside the vertical rods 20, which facilitates the movement of the second pressing roller 7 and makes it convenient to use. Adjustment components are provided on the outer surfaces of the two fixed columns 8. Multiple support blocks 1 are fixedly connected around the bottom of the base 2. The support blocks 1 can provide support for the pressing device, which is very convenient.

[0023] like Figure 3As shown, the adjustment assembly includes a vertical plate 17, which is fixedly connected to the surface of the movable block. An electric push rod 22 is fixedly connected to one side of the surface of the fixed column 8. A push plate 21 is fixedly connected to the surface of the vertical plate 17. The output end of the electric push rod 22 is fixedly connected to the top of the push plate 21. The push plate 21 is moved by the electric push rod 22, which facilitates the driving of the vertical plate 17 and makes the operation more convenient. Both sides of the surface of the two vertical plates 17 are fixedly connected to the brackets 18. The two brackets 18 are slidably installed on the outer surface of the fixed column 8. The movement of the vertical plate 17 outside the fixed column 8 by the brackets 18 can improve the stability of the movement of the vertical plate 17.

[0024] like Figure 1 and Figure 2 As shown, the drive assembly includes a screw 14, with both ends of the screw 14 rotatably connected to the inner wall of the slot 3. A drive block 13 is threadedly connected to the outside of the screw 14. The rotation of the screw 14 facilitates the movement of the drive block 13, making it convenient to use. The connection assembly includes a fixing plate 12, which is fixedly connected to the top of the drive block 13. Two inclined plates 4 are rotatably connected to the surfaces of the fixing plate 12 and the two connecting plates 5. The rotation of the inclined plates 4 facilitates the movement of the fixing post 8 on one side of the fixing plate 12. A motor 15 is fixedly connected to the surface of the base 2. The output end of the motor 15 extends through the inside of the slot 3 and is fixedly connected to one end of the screw 14. The motor 15 can drive the screw 14 to rotate, making the operation more convenient. The inner walls of the two openings 19 are provided with reserved openings 9, which are located between the corresponding first pressing roller 6 and second pressing roller 7. The film will not be obstructed during operation, which is very convenient.

[0025] In use, the bag-making machine places the film between the first and second pressing rollers 6 and 7 at the pre-reserved opening 9. The electric push rod 22 is activated, driving the push plate 21 to move. The push plate 21 then moves the vertical plate 17, which in turn moves the moving block outside the vertical rod 20. This facilitates the movement of the second pressing roller 7, which works in conjunction with the first pressing roller 6 to press the film, preventing lateral shifts and improving product quality and production efficiency while minimizing unnecessary economic losses. When pressing films of different widths, the motor 15 is activated, driving the screw 14 to rotate. The screw 14 then moves the drive block 13, which in turn moves the inclined plate 4. The rotation of the inclined plate 4 facilitates the movement of the connecting plate 5 and the fixed column 8. This design allows for pressing films of different sizes, offering a wide adjustable range and strong applicability, making it worthy of widespread promotion and use, and significantly enhancing its practicality.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
