Description

Technical Field

[0001] This utility model belongs to the technical field of cardboard box processing equipment, and specifically relates to a cardboard box die-cutting machine. Background Technology

[0002] Automated carton production machines, classified by the type of blades used or the type of carton cutting edge, mainly include serrated blades and flat blades. Serrated blades refer to blades with serrated edges, while flat blades are blades without serrations and have a straight cutting edge. Flat blades produce a smooth cutting edge but are more expensive and are therefore only used for high-end gift boxes. Serrated blades produce a rougher cutting edge and are mainly used for low-end packaging boxes such as beer boxes, fruit boxes, and cargo transit boxes.

[0003] A known patent application with application number CN202321542637.4 discloses a carton die-cutting machine: a table with multiple support legs movably connected to the bottom of the table, a conveyor belt at the top of the table, an adjustment mechanism movably installed at the top of the table, and a die-cutting mechanism movably installed on the adjustment mechanism. In use, uncut cardboard is placed above the conveyor belt and conveyed forward by the conveyor belt. By rotating the nut, the external threaded tube moves downward, causing the chassis to move downward so that the ball bearings contact the top of the cardboard. When cutting is required, two telescopic rods on one side are activated to lower the blade holder and the blade to complete the cutting.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above-mentioned technical solution: The device lacks a limiting device, making it prone to deviation when the cutter is cutting the cardboard, causing damage to the carton. Furthermore, since different types of carton require different cutting positions, and some cartons need multiple cuts, the existing device, with only one cutter, cannot quickly die-cut the cardboard. Therefore, a carton die-cutting machine is proposed to solve the above problems. Utility Model Content

[0005] This utility model proposes a carton die-cutting machine, which solves the problem in related technologies where the device lacks a limiting device and the cutter easily deviates when cutting the cardboard.

[0006] The technical solution of this utility model is as follows: a carton die-cutting machine, comprising: a cutting table and a support frame;

[0007] The top of the cutting table is threaded with a first lead screw, and a limit plate is fixedly installed at one end of the first lead screw;

[0008] A hydraulic rod is fixedly installed inside the support frame, and a pressure plate is fixedly installed at the bottom end of the hydraulic rod. A sliding groove is opened inside the pressure plate.

[0009] A second lead screw is slidably mounted inside the groove. A fastener is installed on the external thread of the second lead screw. A clamp is fixedly installed at the bottom end of the second lead screw. A cutting tool is slidably mounted on the external side of the second lead screw.

[0010] Preferably, a motor is fixedly installed inside the cutting table, a first gear is fixedly installed at the output end of the motor, and a limit shaft is rotatably installed inside the cutting table.

[0011] Preferably, a second gear is fixedly mounted on the outside of the limiting shaft, a rotating shaft is rotatably mounted inside the cutting table, and a conveying roller is fixedly mounted on the outside of the rotating shaft.

[0012] Preferably, a third gear is fixedly mounted on the outside of the rotating shaft, and the third gear meshes with the second gear, and the second gear meshes with the first gear.

[0013] Preferably, a rotating handle is fixedly installed at one end of the first lead screw and the second lead screw, and the edges of the rotating handle are ground into rounded arcs.

[0014] Preferably, there are multiple hydraulic rods, and the multiple hydraulic rods are installed in a linear array.

[0015] The working principle and beneficial effects of this utility model are as follows: By rotating the rotary handle, the first lead screw can be rotated, thereby changing the position of the limiting plate, and thus adjusting the two limiting plates. This restricts the movement of the cardboard during cutting, preventing the cardboard from deviating during cutting. By sliding the second lead screw inside the groove and sliding the cutter outside the second lead screw, the position of the cutter can be freely changed, thus adapting to the cutting of different types of cartons. By fixing the first gear to the output end of the motor, the first gear can be driven when the motor is started. The second and third gears then cause the conveyor roller to rotate and convey the cardboard. By grinding the edges of the rotary handle into rounded arcs, scratches can be prevented when turning the rotary handle by hand. By installing multiple hydraulic rods in a linear array, sufficient pressure can be applied to the pressure plate, thus allowing the cutter to cut the cardboard more smoothly.

[0023] Implementation

[0024] Please see Figure 1-4 A carton die-cutting machine includes: a cutting table 1 and a support frame 2;

[0025] The top of the cutting table 1 is threaded with a first lead screw 3, and a limit plate 4 is fixedly installed at one end of the first lead screw 3;

[0026] A hydraulic rod 5 is fixedly installed inside the support frame 2. A pressure plate 6 is fixedly installed at the bottom end of the hydraulic rod 5. A sliding groove 7 is opened inside the pressure plate 6.

[0027] The slide groove 7 has a second lead screw 8 that slides inside. The second lead screw 8 has a fastener 9 that is threaded on its external side. The bottom of the second lead screw 8 has a clamp 18 that is fixedly installed. The second lead screw 8 has a cutting tool 10 that slides on its external side.

[0028] The technical solution provided in this embodiment is as follows: In use, firstly, the first lead screw 3 is rotated by rotating handle 19 to move the limiting plate 4 to a suitable position. Then, the second lead screw 8 is rotated by rotating handle 19 to lock the cutter 10 through fastener 9, preventing the cutter 10 from moving during cutting. Then, the cardboard to be cut is placed on the cutting table 1. Then, the position of the cardboard is restricted by the limiting plate 4. Then, the hydraulic rod 5 is activated to press down the pressure plate 6. The pressure plate 6 presses down the cutter 10, so that the cutter 10 cuts the cardboard. After the cardboard is cut, the motor 11 is activated to rotate the first gear 12, which drives the second gear 14, which drives the third gear 17, and then rotates the rotating shaft 15. Then, the conveyor roller 16 is rotated to convey the cardboard out. Then, the next cardboard to be cut is placed on the cutting table 1 for cutting.

[0029] Furthermore, a motor 11 is fixedly installed inside the cutting table 1, a first gear 12 is fixedly installed at the output end of the motor 11, and a limit shaft 13 is rotatably installed inside the cutting table 1.

[0030] Specifically, by fixing the first gear 12 to the output end of the motor 11, the first gear 12 can be driven when the motor 11 is started, and the conveyor roller 16 can be rotated to convey the cardboard through the second gear 14 and the third gear 17.

[0031] Furthermore, a second gear 14 is fixedly mounted on the outside of the limiting shaft 13, a rotating shaft 15 is rotatably mounted inside the cutting table 1, and a conveying roller 16 is fixedly mounted on the outside of the rotating shaft 15.

[0032] Specifically, by fixing the conveyor roller 16 to the outside of the rotating shaft 15, the conveyor roller 16 can rotate and convey the cardboard when the rotating shaft 15 rotates inside the cutting table 1.

[0033] Furthermore, a third gear 17 is fixedly mounted on the outside of the rotating shaft 15, and the third gear 17 meshes with the second gear 14, while the second gear 14 meshes with the first gear 12.

[0034] Specifically, by engaging the third gear 17 with the second gear 14, and engaging the second gear 14 with the first gear 12, the rotating shaft 15 can be driven to rotate through the second gear 14 and the third gear 17 when the starting motor 11 rotates the first gear 12, thereby causing the conveyor roller 16 to convey the paperboard.

[0035] Furthermore, a rotating handle 19 is fixedly installed at one end of the first lead screw 3 and the second lead screw 8, and the edges of the rotating handle 19 are ground into rounded arcs.

[0036] Specifically, by grinding the edges of the rotating handle 19 into a rounded shape, it is possible to prevent scratches from the edges of the handle when turning the rotating handle 19 by hand.

[0037] Furthermore, there are multiple hydraulic rods 5, and the multiple hydraulic rods 5 are installed in a linear array.

[0038] Specifically, by installing multiple hydraulic rods 5 in a linear array, sufficient pressure can be applied to the pressure plate 6, thereby enabling the cutter 10 to cut the cardboard more smoothly.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
