The base and the mounting plate are connected by connecting columns. There are two clamping columns. The adjusting mechanism includes an adjusting screw, fixed seats and sliding seats. There are two fixed seats, and the two fixed seats are fixedly connected to the base. The two ends of the adjusting screw respectively pass through the two fixed seats and are rotatably connected to the fixed seats. The end of the adjusting screw passing through the fixed seat and away from the base is connected with a driving device. The two ends of the adjusting screw are respectively provided with two sections of threads with opposite helix directions, and the two sliding seats are respectively threadedly connected to the two sections of threads on the adjusting screw. The clamping columns are connected to the sliding seats. The mounting plate is provided with a first sliding hole, and the first sliding hole is a strip-shaped hole. The length direction of the first sliding hole is the same as the length direction of the adjusting screw. The clamping columns pass through the sliding holes and extend away from the base. The invention also includes a variety of selectable bag core molds, and a clamping groove is provided in each of the variety of bag core molds. The clamping groove is in clamping fit with the clamping columns.

[0006] Through the above scheme, by driving the adjusting screw with the driving device, the adjusting screw drives the two sliding seats to approach or move away from each other, thereby driving the two clamping columns to approach or move away from each other, so as to realize the clamping and loosening of the bag core mold. The clamping and loosening operations of the bag core mold in this scheme are convenient, and the efficiency of replacing the bag core mold is effectively improved.

[0007] As a further improvement of the above technical solution, the sliding seat is provided with a sliding block, and the base is provided with a slide rail, and the slide rail is slidably connected to the sliding block.

[0008] Through the above scheme, the cooperation of the sliding block and the slide rail can reduce the friction during the sliding process of the sliding seat.

[0010] As a further improvement of the above technical solution, a second sliding hole is formed in the mounting plate. The second sliding hole is a strip-shaped hole, and the length direction of the second sliding hole is the same as the length direction of the adjusting screw. Each sliding seat is further provided with a guiding column. The guiding columns are arranged in one-to-one correspondence with the second sliding holes. The guiding column includes a rotating shaft and a rotating sleeve. One end of the rotating shaft is fixedly connected to the sliding seat. The rotating sleeve is sleeved on the rotating shaft and is rotatably connected to the rotating shaft. The distance between two corresponding guiding columns on different sliding seats is always smaller than the distance between two corresponding clamping columns on different sliding seats.

[0011] Through the above solution, the guiding columns can guide the packaging bag, avoiding the deviation of the steel pipe during bag sleeving and reducing the quality of bag sleeving.

[0012] As a further improvement of the above technical solution, two guiding columns are provided on each sliding seat. The two guiding columns are respectively arranged on both sides of the clamping column, and the connection line between the two guiding columns is perpendicular to the axis of the adjusting screw.

[0013] As a further improvement of the above technical solution, a packaging machine includes a frame and the universal clamping mechanism for steel pipe and packaging bag core as described above. The universal clamping mechanism for steel pipe and packaging bag core is installed on the frame.

[0014] Through the above solution, by driving the adjusting screw with a driving device, the adjusting screw drives the two sliding seats to approach or move away from each other, thereby driving the two clamping columns to approach or move away from each other, so as to realize the clamping and loosening of the bag core mold. The clamping and loosening operations of the bag core mold in this solution are convenient, effectively improving the efficiency of replacing the bag core mold.

[0015] The beneficial effect of the present invention is that by driving the adjusting screw with a driving device, the adjusting screw drives the two sliding seats to approach or move away from each other, thereby driving the two clamping columns to approach or move away from each other, so as to realize the clamping and loosening of the bag core mold.
