Description

Technical Field

[0001] The utility model belongs to the technical field of web slitting equipment, and more specifically relates to a high-efficiency small web slitter. Background Art

[0002] A long cylindrical web needs to be slit into several short cylinders, generally for toilet paper, and a slitter is used for slitting. The slitting mechanism includes a conveyor belt for the web and a movable and rotatable cutter located at one end of the conveyor belt. A disc cutter is rotatably connected to a bracket, and the disc cutter is driven by a motor to rotate. Every time the conveyor belt transports a certain distance forward, the disc cutter moves to cut the web, and rotates until a long cylindrical web is completely cut into short cylinders.

[0003] During cutting, both sides of the cutting part of the long cylindrical web are pressed by a pressing device to ensure the cutting quality. After one cutting, the pressing device is loosened, the conveyor belt transports forward, the pressing device is pressed again, and the cycle is repeated. In this way, the cutting efficiency is relatively low. Especially when cutting a web with a smaller diameter, the cutting speed is fast, but the repeated pressing and loosening of the pressing mechanism has a greater impact on the overall cutting efficiency of the web. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a small web slitter to improve the cutting efficiency.

[0005] To achieve the above object, the utility model provides the following technical solution: A small web slitter includes a conveyor belt, a cutting mechanism and a support frame respectively located on both sides of the conveyor belt. A support plate is slidably connected to the support frame, and the sliding direction of the support plate is parallel to the conveying direction of the conveyor belt. A plurality of pressing mechanisms are arranged on the support plate, a cutting gap is arranged between adjacent pressing mechanisms, and a driving mechanism is arranged between the support plate and the support frame.

[0006] Further, the pressing mechanism includes a first pressing rod, a first connecting rod and a first pressing cylinder. Two ends of the first connecting rod are respectively hinged to the first pressing rod and the support plate, and one end of the first pressing rod is hinged to the piston rod of the first pressing cylinder.

[0007] Further, a pressing arc plate is arranged on the first pressing rod.

[0008] Further, a buffer mechanism is arranged between the pressing arc plate and the first pressing rod.

[0009] Further, the buffer mechanism includes a second connecting rod. The second connecting rod is slidably connected to the first pressing rod, and a spring is sleeved on the second connecting rod.

[0010] Furthermore, the pressing mechanism includes a second pressing rod and a cylinder bracket. A second pressing cylinder is arranged on the cylinder bracket, and the piston rod of the second pressing cylinder is connected to the second pressing rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the conveyor belt conveys a long cylindrical roll paper, several pressing mechanisms press on the long cylindrical roll paper, and then the support plate moves synchronously with the conveyor belt, so that the disc cutter in the cutting mechanism is located in the cutting gap between two pressing mechanisms, and then the long cylindrical roll paper in the cutting gap is cut. The pressing mechanism on the cut short cylindrical roll paper is then loosened, and the short cylindrical roll paper is conveyed and discharged by the conveyor belt, so that the same long cylindrical roll paper is pressed once before cutting, and the pressing mechanism does not need to be repeatedly loosened and clamped during cutting, improving the cutting efficiency.
