Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The references to "above" and "below" in these embodiments correspond to the directions of "above" and "below" in the accompanying drawings and are provided for ease of description and are not intended to limit the scope of the present invention. Any changes or adjustments to these relative relationships, without materially altering the technical content, should be considered within the scope of the present invention.

[0018] Depend on Figure 1As shown, an adjustable packaging bag punching mechanism that is convenient for replacing molds includes a universal base 1, a pair of T-shaped guide rails 11 are provided on the universal base 1, and a pair of support frames 14 are provided on the left and right sides of the T-shaped guide rails 11. The top surface of the top plate of each support frame 14 is provided with a driving cylinder 15, and the output shaft of the driving cylinder 15 passes through the top plate of the support frame 14 and is connected to a driving pressure beam 16. A pair of vertical guide seats 12 are provided at the front and rear ends of the universal base 1, and the inner wall of the vertical guide seat 12 is provided with a vertical guide groove 121. The driving pressure beam 16 is in the shape of an I-shape. The front and rear ends of the driving pressure beam 16 are slidably arranged in the vertical guide groove 121. The inner wall of the vertical guide seat 12 is provided with an adjustable limit frame 13. The limit frame 13 can be adjusted forward and backward to adapt to packaging bags of different widths. A punching device 2 is slidably provided on the T-shaped guide rail 11. The punching device 2 is always directly below the driving pressure beam 16. The operation of the punching device 2 can be realized by lifting and lowering the driving pressure beam 16. The punching device 2 can be fixed on the universal base 1 by various connecting parts such as bolts and limit blocks.

[0019] Depend on Figures 2 to 3 As shown, the punching device 2 includes a sliding base 20 slidably arranged on the T-shaped guide rail 11, the top surface of the sliding base 20 has a pressure groove 201 that can be used to install a pressure mold, and a pair of support seats 23 are provided on the left and right sides of the pressure groove 201, each support seat 23 is provided with a vertical groove 231, and a vertical guide rod 24 is provided in the vertical groove 231. The two vertical guide rods 24 are sequentially sleeved with a support spring 242, a fastening frame 26, a punching compression spring 241 and a lifting beam 25 from bottom to top, and a mold mounting plate 27 is provided on the lifting beam 25. The mold mounting plate The plate 27 is in a convex shape. The bottom plate of the mold mounting plate 27 cooperates with the fastening frame 26. The elastic force of the punching compression spring 241 is greater than the supporting spring 242. When the lifting beam 25 descends, the punching compression spring 241 first causes the fastening frame 26 to descend. After the fastening frame 26 is pressed against the packaging bag, the punching mold in the mold mounting plate 27 is pressed toward the packaging bag. A plurality of fastening holes 271 are provided on the bottom plate of the mold mounting plate 27. The first threaded portion 311 of the circular hole mold 31 and the second threaded portion 322 of the slotting mold 32 can both cooperate with the fastening holes 271 and be fastened by nuts.

[0020] Depend on Figure 2 As shown, guide rollers 21 are provided in the grooves at the front and rear ends of the top surface of the sliding base 20, and a wear-resistant column 28 is provided at the center of the top surface of the lifting beam 25. The wear-resistant column 28 is located below the driving pressure beam 16. Lock holes 202 are provided on the left and right sides of the pressure groove 201, and the limiting shaft of the lock buckle 22 is inserted in the lock hole 202. After the corresponding pressure mold is placed in the pressure groove 201, the pressure mold can be fixed by the lock buckle 22.

[0021] The working principle of this utility model:

[0022] The entire packaging bag punching mechanism is arranged between the discharging mechanism and the receiving mechanism. Then, according to actual processing requirements, one or more punching devices 2 can be arranged on the universal base 1, and the position of the punching device 2 can be adjusted. During operation, the driving cylinder 15 can make the entire driving pressure beam 16 rise and fall, so that all the punching devices 2 can punch or groove at the same time. When the driving pressure beam 16 is pressed down, it must lean on the wear-resistant column 28. When the lifting beam 25 descends, the punching pressure spring 241 and the support spring 242 will be deformed. Since the elastic force of the punching pressure spring 241 is greater than the support spring 242, the support spring 242 takes longer to deform than the punching pressure spring 241. Therefore, the fastening frame 26 will first be lowered until it is pressed against the packaging bag, and the packaging bag will be fastened before punching or grooving to ensure that the packaging bag is deformed during punching or grooving. Then the circular hole mold 31 or the slotting mold 32 fixed in the mold mounting plate 27 is pressed toward the packaging bag to complete the punching or grooving.
