Description

Technical Field

[0001] The utility model relates to the technical field of printing and slitting equipment, in particular to a slitting machine used for packaging printing. Background Art

[0002] After the materials of conventional packaging bags are gravure printed, they need to be cut according to the designed length of the packaging bags before subsequent processing can be carried out. In the actual slitting step, the ends of conventional packaging tapes are easily bent due to the material characteristics. If they are plastic materials such as PE, wrinkles will also occur. The conventional cutting mechanism that uses lifting and lowering adjustment is likely to cause uneven cut surfaces of the wrinkled parts of the material, affecting product quality. In addition, for relatively thin packaging materials, it is not convenient to transport the cut materials after the size becomes smaller. Utility Model Content

[0003] The utility model aims to provide a slitting machine for packaging printing, which solves the problems that the conventional slitting machine for packaging printing is prone to wrinkles due to material characteristics, affecting the flatness of the incision, and the slit packaging material is inconvenient to transport.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] The utility model provides a slitting machine for packaging printing, comprising a slitting support platform, a top plate arranged directly above the slitting support platform through a plurality of support rods, a slitting telescopic cylinder vertically arranged on the top plate, a slide seat slidably sleeved on the support rod and adjusted to rise and fall by the slitting telescopic cylinder, and a slitting knife arranged at the bottom of the slide seat and used for cutting the packaging roll tape;

[0006] A conveying roller and a pressing roller used in conjunction with the conveying roller are respectively arranged on one side of the slitting support platform; a slope smoothly transitioning to the top surface of the slitting support platform is arranged on the other side of the slitting support platform;

[0007] A material guide roller close to the slope is arranged in the middle of the slope and is adjusted by a horizontal adjustment telescopic cylinder;

[0008] A conveyor belt for conveying the cut products is arranged at the bottom of the slope.

[0009] Furthermore, the conveying surface of the conveying roller is flush with the conveying surface of the slitting support table, so as to ensure smooth conveyance of the printed packaging tape.

[0010] Furthermore, the top plate is mounted on the slitting support platform through four support rods, and the slitting telescopic cylinder thereon is an electric telescopic cylinder. Specifically, the slitting telescopic cylinder can be replaced by a motor, an eccentric wheel, and a connecting rod connecting the slide seat.

[0011] Furthermore, four linear bearings or sleeves respectively matched with the support rods are installed on the slide seat, so that the slide seat can slide smoothly on the support rod.

[0012] Furthermore, a first support plate and a second support plate are provided above the conveyor belt through a bracket, spanning the conveying surface thereof;

[0013] Two guide rods are provided through the first support plate and the second support plate, and a U-shaped frame is installed at the ends of the two guide rods;

[0014] The two ends of the guide roller are mounted on the U-shaped frame through bearings, and the rotating shaft is driven to rotate by a servo motor mounted outside the U-shaped frame;

[0015] A horizontal adjustment telescopic cylinder for adjusting the horizontal extension and retraction of the U-shaped frame is also arranged on the first support plate.

[0016] Furthermore, a meter is provided on the conveying line of the packaging tape.

[0017] Compared with the prior art, the beneficial technical effects of the utility model are:

[0018] In the present application, the U-shaped frame is connected by the telescopic end of the horizontally adjustable telescopic cylinder, thereby driving the guide roller to press against the slope, so that the packaging tape under the slitting knife can be in a tensioned state on the slitting support table to ensure the slitting accuracy of the slitting knife; in addition, the servo motor can be used to drive the guide roller to rotate, so that the slit packaging tape product can be smoothly dropped onto the conveyor belt for rapid transportation and transfer.
