Description

Technical Field

[0001] This utility model relates to the field of cardboard box cutting technology, and in particular to a cardboard box cutting device. Background Technology

[0002] The raw materials for carton production (such as corrugated cardboard and cardboard) are usually purchased in large rolls or sheets. They need to be processed into cardboard components of specific specifications (such as boxboards, side panels, bottom panels, etc.) by cutting equipment before they can be further processed into complete cartons through folding, gluing, and nailing processes.

[0003] Existing carton cutting devices often require manual intervention for carton conveying and cutting during installation and use. This not only increases labor intensity but also leads to low production efficiency, difficulty in ensuring batch cutting consistency, and easy dimensional deviations, which have certain adverse effects on users. In order to overcome the shortcomings of existing technologies, we propose a carton cutting device. Utility Model Content

[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0016] Example 1, as Figures 1-4As shown, a carton cutting device includes a base 1, a fixed frame 17 fixedly mounted on the upper end of the base 1, a transmission screw 8 and a balance bar 15 arranged in parallel inside the fixed frame 17, a second movable frame 13 slidably sleeved on the outer wall of the balance bar 15, a third movable frame 14 connected to the outer wall of the transmission screw 8 by threads, a first movable frame 11 welded between the third movable frame 14 and the second movable frame 13, an electric telescopic rod 4 mounted on the upper end of the first movable frame 11, a cutter 12 connected to the lower end of the electric telescopic rod 4 by threads, and a first motor 3 connected to one end of the transmission screw 8 for driving the transmission screw 8 to rotate, thereby causing the third movable frame 14 to move laterally.

[0017] Example 2, as Figures 1-4 As shown, a carton cutting device includes two sets of connecting rods 16 symmetrically arranged on the upper end of a base 1. Rollers 2 are rotatably mounted on the outer wall of the connecting rods 16. Two sets of transmission rods 7 are also provided, with a drive roller 5 fixed to the outer wall of the transmission rods 7. One end of each set of transmission rods 7 is respectively equipped with a drive sprocket 6 and a sprocket 10. The drive sprocket 6 meshes with the sprocket 10 through a transmission chain 9. The other end of the drive sprocket 6 is connected to a second motor 18, forming a carton conveying drive mechanism. The transmission screw 8 is movably connected to the fixed frame 17 through a bearing to ensure the stable rotation of the transmission screw 8. The cutter 12 is threadedly connected to the electric telescopic rod 4 for easy disassembly and replacement. Both the drive sprocket 6 and the sprocket 10 mesh with the transmission chain 9. The transmission rods 7 are movably connected to the base 1 through bearings to ensure the smooth transmission of conveying power. The outer walls of both the rollers 2 and the drive roller 5 are wrapped with silicone rings to increase friction and improve the stability of carton conveying.

[0018] The user places the cardboard box to be cut under roller 2 and drive roller 5, and starts the second motor 18. Its output shaft drives the drive sprocket 6 to rotate, which in turn drives the sprocket 10 to rotate via the transmission chain 9, thereby causing the two sets of transmission rods 7 to rotate synchronously. The drive roller 5 rotates with the transmission rods 7, cooperating with roller 2 to drive the cardboard box forward.

[0019] According to the carton cutting size requirements, the number of rotations of the first motor 3 is set through the control system. The first motor 3 drives the transmission screw 8 to rotate. Since the third movable frame 14 is threadedly connected to the transmission screw 8, the third movable frame 14 will move axially along the transmission screw 8. At the same time, the second movable frame 13 slides synchronously on the balance bar 15, driving the first movable frame 11, the electric telescopic rod 4, and the cutter 12 to move laterally to the designated cutting position.

[0020] The electric telescopic rod 4 extends downwards, driving the cutter 12 to cut the cardboard box. After cutting, the electric telescopic rod 4 retracts, the first motor 3 reverses to make the transmission screw 8 rotate in the opposite direction, and the cutter 12 returns to its initial position, waiting for the next cutting command.

[0021] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
