Technical Field

[0001] This utility model relates to the field of corrugated cardboard box production technology, specifically a longitudinal cutting unit for corrugated cardboard box production. Background Technology

[0002] Corrugated cardboard boxes, as an important packaging material, play a vital role in logistics, transportation, and other industries. With increasing market demand, corrugated cardboard box manufacturers are constantly raising their requirements for production efficiency and quality. Especially in the corrugated cardboard box cutting process, traditional slitting equipment can no longer meet the demands of modern production lines for efficient, continuous, and stable cutting, and urgently needs improvement.

[0003] Existing slitting devices have certain limitations. During the cutting process, especially at high-speed production, the equipment exhibits poor operational stability, easily leading to tool jamming, incomplete cutting, or breakage, thus reducing production efficiency. Furthermore, existing slitting devices cannot achieve automated, continuous, and efficient cutting, frequently requiring manual intervention or equipment shutdown for maintenance and adjustments, further impacting the overall operational efficiency of the production line.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a longitudinal cutting unit for corrugated cardboard box production. Utility Model Content

[0011] The blade, fixed to the other end of the linkage blade arm, is used to perform longitudinal cutting of corrugated cardboard.

[0012] As a preferred technical solution, the positioning protrusion is used to limit the lateral displacement of the linkage blade arm.

[0013] As a preferred technical solution, the eccentric disk one and the eccentric disk two have different eccentricities, which are used to drive the linkage arm to achieve multi-track reciprocating motion. The eccentric disk linkage port one and the eccentric disk linkage port two are elongated through holes, and their length direction is consistent with the movement direction of the linkage arm.

[0014] As a preferred technical solution, the blade has a detachable structure, and its cutting edge is made of a high-hardness alloy material.

[0015] As a preferred technical solution, the motor is a servo motor, whose speed and direction are adjusted by an external controller to achieve precise control of cutting speed and stroke.

The fixing base 1 is used to support the structure of the entire longitudinal cutting unit and ensure its stability during the production process.

[0024] like Figure 2 As shown, the drive mechanism includes a motor 21, a drive shaft 22 connected to the motor 21, and eccentric disks 23 and 24 fixed on the drive shaft 22. The motor 21 serves as a power source, transmitting power to the eccentric disks 23 and 24 via the drive shaft 22 to achieve the reciprocating motion of the linkage tool arm 3.

[0025] like Figure 3 As shown, one end of the linkage cutter arm 3 is provided with a tail positioning movable port 31, which is connected to the positioning protrusion 11 on the fixed base 1. The linkage cutter arm 3 is also provided with an eccentric disk linkage port 1 32 and an eccentric disk linkage port 2 33, which are connected to the eccentric disk 1 23 and the eccentric disk 2 24 respectively. The linkage cutter arm 3 realizes multi-track reciprocating motion under the drive of the eccentric disk.

[0026] Blade 34 is fixed to the other end of the linkage cutter arm 3 and is used to perform longitudinal cutting of corrugated cardboard. Blade 34 adopts a detachable structure, and its cutting edge is made of high-hardness alloy material, which is convenient for replacement and maintenance.

[0027] In this embodiment, the positioning protrusion 11 is used to limit the lateral displacement of the linkage cutter arm 3, ensuring the accuracy of the cutting process.
