Description

Technical Field

[0001] The utility model relates to the technical field of corrugated carton production, in particular to a cutting device for corrugated carton production. Background Technique

[0002] Corrugated cartons are a widely used packaging container, which are made from corrugated cardboard through processes such as die-cutting, indentation, box nailing or gluing. Corrugated cardboard is usually composed of three or more layers of face paper, corrugated core paper and inner paper, and has good cushioning performance and support strength, which can effectively protect the internal goods from impact and pressure during transportation. Due to its light weight, durability, easy folding and assembly, relatively low cost and environmental friendliness, corrugated cartons play an extremely important role in the modern logistics and packaging industries.

[0003] During the production of corrugated cartons, a cutting device is required. Traditional cutting devices lack structures for positioning and limiting the corrugated cardboard, resulting in easy occurrence of slight or obvious offsets in the position of the corrugated cardboard during cutting, thereby affecting the straightness and dimensional accuracy of cutting and reducing the quality of the corrugated cardboard after cutting. Content of the Utility Model

[0007] Through the above technical solutions, the motor drives the bidirectional lead screw to rotate, so that the two nut seats move closer to each other, driving the position of the mounting plate to move, which is convenient for adjusting according to the size of the corrugated cardboard, thereby improving the flexibility during use. The cylinder pushes the limiting plate to move downward, so that the buffer spring and the rubber pressing plate move downward, making the rubber pressing plate contact the surface of the corrugated cardboard to limit and fix the corrugated cardboard, avoiding displacement of the corrugated cardboard during cutting, and thus improving the quality after cutting.

[0008] As a further improvement of the above solution, the left end of the motor is fixedly connected to the inner wall of the motor base, both ends of the bidirectional lead screw are rotatably connected to the inner wall of the cutting workbench, the bidirectional lead screw is located inside the groove, and the surface of the nut seat is slidably connected to the inner wall of the groove.

[0009] Through the above technical solution, the bidirectional lead screw located inside the groove avoids the contact between the corrugated cardboard and the bidirectional lead screw, and the position of the nut seat is limited by the groove, so that the nut seat maintains a linear motion.

[0010] As a further improvement of the above solution, the number of the nut seats is set to two, the two nut seats are symmetrically distributed with the cutting workbench as the center, one end of the limiting plate and the rubber pressing plate are both slidably connected to the inner wall of the limiting groove, and the number of the buffer springs is set to several.

[0011] Through the above technical solution, the limiting groove limits the limiting plate and the rubber pressing plate, ensuring the stability of the limiting plate and the rubber pressing plate during movement.

[0013] Through the above technical solution, the avoidance groove avoids the contact between the cutting knife and the workbench when the cutting knife descends, realizes the protection of the cutting knife, and prolongs the service life of the cutting knife.

[0014] As a further improvement of the above solution, the top of the fixed frame is fixedly connected with a hydraulic rod, and the output end of the hydraulic rod penetrates through the fixed frame and is fixedly connected with an installation frame.

[0015] Through the above technical solution, the hydraulic rod pushes the installation frame to move downward, so that the cutting knife moves to realize the cutting of the corrugated cardboard.

[0016] As a further improvement of the above solution, a cutting knife is fixedly connected to the inner wall of the installation frame, and a limiting rod is fixedly connected to the top of the installation frame.

[0017] As a further improvement of the above solution, the surface of the limiting rod is slidably connected to the inner wall of the fixed frame, the number of the limiting rods is set to two, and the two limiting rods are symmetrically distributed with the fixed frame as the center.

[0018] Through the above technical solution, the limiting rod limits the installation frame, so that the installation frame maintains a vertical movement, improving the stability during use.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] By setting a fixing component, specifically, the bidirectional lead screw is driven by a motor to rotate, so that the two nut seats move closer to each other, driving the position of the mounting plate to move, which is convenient for adjusting according to the size of the corrugated cardboard, thereby improving the flexibility during use. The limiting plate is pushed downward by the air cylinder, so that the buffer spring and the rubber pressing plate move downward, making the rubber pressing plate contact the surface of the corrugated cardboard to limit and fix the corrugated cardboard, avoiding the displacement of the corrugated cardboard during cutting. The buffer spring provides a flexible pressure, avoiding damage to the corrugated cardboard due to excessive pressure, and at the same time being convenient for adjusting according to corrugated cardboard of different thicknesses, thereby improving the quality after cutting.

[0021] By setting an avoidance groove, specifically, through the avoidance groove, unnecessary contact between the cutting knife and the cutting workbench during the descending process is avoided, thereby protecting the cutting workbench and the cutting knife and prolonging the service life of the cutting knife.
