Description

Technical Field

[0001] The utility model belongs to the technical field of automatic turning structures of carton cutting machines, in particular to an automatic turning device for carton cutting machines. Background Art

[0002] A carton cutting machine is a high-end automated CNC equipment that integrates cutting, line drawing, creasing, dotted line, drawing and other functions. It is widely used in carton production processes. In the prior art, there are various types of carton cutting machines. When cutting carton paperboard, it is generally necessary to flip it over to complete the cutting operation. However, most of the existing carton cutting machines are not equipped with a flipping mechanism and need to be flipped manually. This is not only cumbersome to operate and less convenient, but also increases the workload of operators.

[0003] A Chinese patent document (application publication number CN218777180U) discloses a carton cutting machine, which comprises a workbench, wherein sliding devices are respectively provided on the walls on both sides of the workbench, a CNC tool holder is fixedly installed between the sliding devices, an electric slide rail is installed on the lower wall of the lateral end of the CNC tool holder, an electric push rod is installed on the movable end of the electric slide rail, and a tool is fixedly installed on the telescopic end of the electric push rod.

[0004] It can be seen that the patent document cited above also has the same problem. Although it realizes the movement of the tool without dead angles in the plane, it lacks a flipping mechanism. When flipping and cutting the carton, it needs to be flipped manually. This is not only cumbersome and inconvenient, but also increases the workload of the operator. Utility Model Content

[0005] The utility model aims to provide an automatic turning device for a carton cutting machine to solve the problems raised in the background technology.

[0007] As a preferred embodiment, the fixing assembly includes a fixing block, a second screw rod is penetrated through the top end of the fixing block, a torsion is installed at the top end of the second screw rod, and a clamp is installed at the bottom end of the second screw rod.

[0008] As a preferred embodiment, a fixing groove is provided on the side of the top end of the cutting machine body, and the depth of the fixing groove is greater than the height of the limiting plate.

[0009] As a preferred embodiment, the outer wall of the first screw rod passes through the connecting frame, and one end of the first screw rod is connected to the inner wall bearing of the connecting frame.

[0010] As a preferred embodiment, limit blocks are installed on both sides of the top end of the rack.

[0011] As a preferred embodiment, a shaft seat is installed at the top of the connection frame, and one side of the shaft seat is interlaced and connected with the outer wall of the transmission shaft.

[0012] As a preferred embodiment, two limiting sliders are installed on one side of the clamping plate.

[0013] Compared with the prior art, the technical effects and advantages of the utility model are as follows:

[0014] The automatic flipping device of the carton cutting machine benefits from the design of the electric push rod, motor, rack, transmission gear and fixed component. After the carton is fixed by the fixed component, the electric push rod is used to drive the limit plate to move upward, and then the motor switch is turned on. The motor drives the rack to move to the left, and then the limit plate is driven to rotate through the transmission gear. Then the electric push rod is reset to make the bottom of the carton fit with the top of the cutting machine body. In this way, the carton can be automatically flipped. The whole flipping process does not require manual operation, and the flipping is convenient. At the same time, the work intensity of the operator is reduced. At the same time, the design of the fixed component is not only convenient for subsequent flipping operations, but also can prevent the carton from moving during cutting, avoiding cutting deviation.

[0015] By opening a fixing groove at the top of the cutting machine body, the fixing groove can make way for the fixing components after the carton is turned over, so that the turned carton can fit the top of the cutting machine body again, which is convenient for cutting.
