Description

Technical Field

[0001] The utility model belongs to the technical field of cutting equipment, and in particular relates to a cutting equipment for carton production. Background Art

[0002] Cartons are the most widely used packaging products. According to different materials, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Commonly used cartons are three-layer and five-layer, and seven-layer is less used. Each layer is divided into lining paper, corrugated paper, core paper, and face paper. The face paper includes tea board paper and kraft paper, and the core paper is corrugated paper. During the production process of cartons, cartons are cut into preset sizes as needed.

[0003] The existing carton cutting equipment does not limit the position of the carton during the cutting process. The cutting knife may easily cause the position of the carton to deviate when cutting the carton, resulting in poor cutting effect and defective products, thereby reducing the efficiency of carton cutting and increasing production costs.

[0004] Therefore, in order to solve the above problems, it is necessary to design a cutting device for carton production. Utility Model Content

[0014] The arc portion is suitable for guiding the carton board.

[0015] Furthermore, the cutting mechanism further comprises: guide posts arranged on both sides of the support frame, a connecting pipe connected to the two guide posts and a knife seat for fixing the cutting knife; wherein

[0016] The knife seats are respectively sleeved on the two guide posts and are slidably connected with the guide posts.

[0017] Furthermore, the cutting mechanism further comprises: a spring sleeved on the guide post;

[0018] The spring is arranged between the support frame and the knife seat.

[0019] Furthermore, the cutting mechanism further comprises: a rotating shaft connected to the bearing of the support frame, a rotating disk sleeved on both ends of the rotating shaft, and a transmission rod connected to the rotating disk bearing; wherein

[0020] The other end of the transmission rod is connected to the knife seat bearing.

[0021] Furthermore, the cutting mechanism further comprises: a reducer for driving the rotating shaft to rotate and a second motor for driving the reducer; wherein

[0022] The reducer is arranged on the support frame; and

[0025] (I) The utility model extends two cylinders to drive two limit plates to move respectively, so as to adjust the distance between the limit plates, start the first motor, and drive any one conveying roller to rotate. The conveying roller cooperates with another conveying roller to make the conveyor belt convey the carton board. When the carton board is tilted, the two limit plates correct it before the cutting knife cuts it, so as to prevent the carton board from tilting and causing defective products.

[0026] (ii) The utility model starts the second motor, and the second motor drives the shaft to rotate through the reducer, and the shaft drives the turntable to rotate. When the bearing connection between the turntable and the transmission rod rotates from the highest point to the lowest point, the transmission rod drives the knife seat to move downward, and the knife seat drives the cutting knife to cut the carton board. At the same time, the knife seat compresses the spring.
