Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing, and in particular to a cutting edge machine for cardboard box processing. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Corrugated cardboard boxes are the most widely used packaging products, such as beer packaging boxes. Due to their superior performance and good processing properties, corrugated cardboard boxes have become the mainstay of transport packaging.

[0003] Currently, when trimming the edges of cardboard boxes, one side of the box is cut first, and then the other side is cut manually by flipping the box over. This method is slow. If both sides of the box are cut directly, it can only be used for boxes of a fixed size, which is quite limiting.

[0004] Therefore, it is necessary to invent a cutting machine for cardboard box processing to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a cutting machine for carton processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a trimming machine for carton processing, comprising two fixed frames, a conveyor belt connecting the two fixed frames, a horizontal plate connected to the top of each of the two fixed frames, a top plate connected to the top of the two horizontal plates, a square rod connected between the two horizontal plates, a first motor connected to the side wall of one of the horizontal plates, the output end of the first motor connected to the right end of the square rod, two square cylinders slidably disposed on the outer wall of the square rod, a first pulley connected to the outer wall of the square cylinders, a fixed cylinder connected to the outer wall of the square cylinders via bearings, a fixed plate connected to the bottom of the fixed cylinders, a rotating shaft connected to the side wall of the fixed plate, a second pulley connected to the outer wall of one end of the rotating shaft, a transmission belt disposed between the second pulley and the first pulley, a cutting blade connected to the other end of the rotating shaft, a cutting groove corresponding to the cutting blade being opened on the top of each of the two fixed frames, and an adjustment assembly disposed between the two horizontal plates.

[0007] Preferably, each of the two fixing frames has two support legs connected to its bottom, and the bottom of each support leg is connected to a stabilizing plate.

[0008] Preferably, the bottom of the top plate is connected to two support plates, each of the support plates has a groove at its bottom, and a push rod is connected in the groove. The bottom of the push rod is connected to a U-shaped frame, the top of the U-shaped frame is connected to a spring, the other end of the spring is connected to the bottom of the support plate, and multiple pressure rollers are rotatably arranged inside the U-shaped frame.

[0009] Preferably, the adjusting assembly includes a bidirectional lead screw connected between the two horizontal plates. Two moving blocks are connected to the outer wall of the bidirectional lead screw. A fixed rod is connected to the bottom of each of the two moving blocks. The bottom of the fixed rod is connected to the top of the fixed cylinder. A second motor is connected to the side wall of the other horizontal plate. The output end of the second motor is connected to the left end of the bidirectional lead screw.

[0010] Preferably, a guide rod is connected between the two horizontal plates, and guide holes corresponding to the guide rod are opened on the side walls of the two moving blocks.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] By using a second motor to drive a bidirectional lead screw to rotate, the bidirectional lead screw drives two moving blocks to move. The moving blocks pull a fixed rod, the fixed rod pulls a fixed cylinder, and the fixed cylinder pulls a square cylinder and a fixed plate, causing the square cylinder to slide on the square rod and the two fixed plates to move closer or further apart, thereby adjusting the distance between the two cutting blades. By using a first motor to drive a square rod to rotate, the square rod drives the two square cylinders to rotate, the square cylinders drive the first pulley to rotate, the first pulley drives the second pulley to rotate via a transmission belt, the second pulley drives the rotating shaft to rotate, and the rotating shaft drives the cutting blade to rotate. The cutting blade is used to cut both sides of the carton, which can conveniently cut both sides of cartons of different sizes at the same time, thereby improving the cutting efficiency of the carton.
