Description

Technical Field

[0001] This utility model belongs to the field of die-cutting technology, specifically relating to a die-cutting blade for a carton die-cutting machine. Background Technology

[0002] Cardboard boxes are an essential item in people's production and daily life. Before they are glued or stapled, all kinds of cardboard boxes need to be cut to form the corresponding pattern. Nowadays, the cutting work is generally carried out by a cutting machine. The main working part of the cutting machine is the die, which is used to process the cardboard boxes.

[0003] For example, in the Chinese utility model publication CN221605266U entitled "A Carton Cutting Die with a Limiting Protection Mechanism," a base is included, and a support plate is fixedly installed at the rear end of the top side of the base. The aforementioned prior art drives the mounting box and cutting die disc to move down and engage with the die slot by starting the first electric push rod, and then starts the first motor to drive the lead screw body to rotate, which in turn drives the lead screw sleeve and connecting mechanism to move laterally. However, when die-cutting cardboard of different thicknesses, there is no pressure adjustment, which makes the die easy to be damaged. Therefore, in order to improve the service life of the die, a die-cutting knife for a carton die-cutting machine is needed. Utility Model Content

[0004] The purpose of this invention is to provide a die-cutting blade for a carton die-cutting machine that has a simple structure and reasonable design in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A die-cutting blade for a carton die-cutting machine includes a lower die base, multiple support columns, a blade holder, a die-cutting blade, and a baffle. One end of each of the multiple support columns is fixedly mounted on the top of the lower die base, and the blade holder is slidably mounted on the other end of each of the multiple support columns. A pressure balancing assembly is provided at the bottom of the blade holder, and a fixing assembly is provided at the top of the lower die base. The outer side of the die-cutting blade is disposed inside the pressure balancing assembly, and the top of the baffle is fixedly mounted at the bottom of the pressure balancing assembly.

[0006] As a further optimization of this utility model, the pressure balancing assembly includes multiple connecting columns slidably connected inside the tool holder. The bottom ends of the multiple connecting columns are fixedly connected to an upper mold base. The top of the upper mold base is fixedly connected to a screw that slides through the inside of the tool holder. One end of the screw is threadedly connected to a nut that contacts the top of the tool holder. Springs are sleeved on the outside of the screw and the multiple connecting columns.

[0007] As a further optimization of this utility model, the two ends of the spring are respectively fixedly connected to the top of the upper mold base and the bottom of the tool holder, and a scale rod that slides through the inside of the tool holder is fixedly connected to the top of the upper mold base.

[0008] As a further optimization of this utility model, the fixing component includes multiple mounting brackets fixedly connected to the top of the lower mold base. Each of the multiple mounting brackets is rotatably connected to a rotating plate. The rotating plate is fixedly connected to a mounting plate rotatably connected to the outside of the mounting bracket. The mounting bracket is detachably connected to a pin that slides through the rotating plate and the inside of the mounting plate.

[0009] As a further optimization of this utility model, the mounting plate is provided with multiple support plates on its exterior, and bolts are threaded through the interior of each of the multiple support plates, with a rubber post fixedly connected to one end of each bolt.

[0010] As a further optimization of this utility model, a fixing groove is provided inside the upper mold base, and the external fixed connection of the die-cutting blade is fixed in the fixing groove.

[0011] The beneficial effects of this utility model are as follows: This invention uses a rotating nut to move the upper die base, causing the spring to move accordingly. By observing the changes in the scale rod, the pressure can be precisely adjusted by rotating the nut, reducing die wear and preventing excessive wear of the die edge on thin cardboard due to excessive pressure, or repeated die cutting of thick cardboard due to insufficient pressure, which increases the burden on the die and extends the die life.

[0012] This invention involves rotating the rotating plate by holding its handle, which lifts the mounting plate and places the cardboard to be die-cut on the lower die base. Then, the operation is reversed to align the mounting plate with the hole in the mounting bracket. The pin is then inserted to secure the mounting plate. Next, the bolts are adjusted to bring the rubber post into contact with the cardboard. The above fixing steps are repeated to firmly secure the cardboard on the lower die base, after which the die-cutting operation can be performed. This effectively prevents the carton from shifting during die-cutting, ensures accurate cutting position, reduces dimensional deviation, and improves the regularity and pass rate of the formed carton.

Detailed Implementation

[0015] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0016] like Figure 1 , Figure 3 As shown, a die-cutting blade for a carton die-cutting machine includes a lower die base 1, which is the basic load-bearing component of the equipment and provides a stable support platform for the entire die-cutting operation. The lower die base 1 includes four support columns 2, a blade holder 3, a die-cutting blade 4, and a baffle 7. One end of each of the four support columns 2 is fixedly mounted on the top of the lower die base 1 to ensure the accuracy of the subsequent sliding trajectory of the blade holder 3. The blade holder 3 is slidably mounted inside the other end of the multiple support columns 2 to prevent the blade holder 3 from deforming due to excessive force on one side and to extend the service life of the blade holder 3.

[0017] like Figure 1 , Figure 2 , Figure 3As shown, a pressure balancing assembly 5 is provided at the bottom of the blade holder 3. The pressure balancing assembly 5 is used to adjust the pressure when die-cutting cardboard of different thicknesses, thereby improving its service life. The die-cutting blade 4 is externally located inside the pressure balancing assembly 5. By adjusting its own structure, the die-cutting blade 4 is subjected to uniform force during die-cutting, preventing excessive wear in certain areas and extending its service life. The top of the baffle 7 is fixedly located at the bottom of the pressure balancing assembly 5 to prevent the die-cut carton from being lifted along with the blade holder 3. The pressure balancing assembly 5 includes four connecting posts 501, which are used to balance the pressure. The balancing component 5 provides guidance. The four connecting columns 501 are slidably connected to the inside of the tool holder 3, ensuring smooth pressure adjustment. The bottom of each of the four connecting columns 501 is fixedly connected to an upper mold base 502. The upper mold base 502 serves as the mounting carrier, and its slidable connection to the connecting columns 501 ensures stability during lifting and lowering. A screw 504 is fixedly connected to the top of the upper mold base 502. The screw 504 is a crucial component for pressure adjustment. One end of the screw 504 slides through the inside of the tool holder 3, providing a foundation for pressure adjustment. A nut 505 is threaded onto one end of the screw 504. The nut 505 is used to cooperate with the screw 504 to drive the upper die holder 502 to rise and fall. The outside of the nut 505 contacts the top of the tool holder 3. A scale rod 506 is fixedly connected to the top of the upper die holder 502. The scale rod 506 is provided with multiple scale lines, which can intuitively reflect the rising and falling distance of the upper die holder 502, so that the operator can know the pressure change and make it easy to adjust the pressure accurately. The outside of the scale rod 506 slides through the inside of the tool holder 3, so that the scale rod 506 can move synchronously with the upper die holder 502 to ensure the accuracy of the scale display. Springs 50 are sleeved on the outside of the four connecting columns 501. 3. Spring 503 is used to change the pressure when nut 505 rotates. The pressure change is observed by scale and the die-cutting pressure is manually balanced. One end of spring 503 is fixedly connected to the top of upper die holder 502, and the other end of spring 503 is fixedly connected to the bottom of knife holder 3. The upper die holder 502 has a fixing groove inside, which can position and fix the die-cutting knife 4 to prevent the die-cutting knife 4 from loosening or shifting during the die-cutting process. The die-cutting knife 4 is fixedly connected to the outside of the fixing groove to ensure that the die-cutting knife 4 moves synchronously with the upper die holder 502, and to ensure the stability and accuracy of the die-cutting action.

[0018] like Figure 1 , Figure 4As shown, a fixing component 6 is provided on the top of the lower die base 1. The fixing component 6 can fix the cardboard to be die-cut on the lower die base 1 to prevent the cardboard from sliding during the die-cutting process and ensure the die-cutting accuracy. The fixing component 6 includes two mounting brackets 601, which serve as the mounting base to ensure the normal operation of each component of the fixing component 6. The bottom of both mounting brackets 601 is fixedly connected to the top of the lower die base 1 to prevent the mounting brackets 601 from falling off during use. Rotating plates 602 are rotatably connected to the outside of both mounting brackets 601. A handle is installed on the upper end of the rotating plate 602 for easy operation. A mounting plate 603 is fixedly connected to the outside of the rotating plate 602. The mounting plate 603 is connected to the rotating plate 602. The rotating plate 602 rotates around the mounting bracket 601 to drive the opening and closing of the mounting plate 603. One end of the mounting plate 603 is rotatably connected to the outside of the mounting bracket 601 to ensure the stability of the mounting plate 603 when opening and closing and to avoid jamming. The mounting bracket 601 is detachably connected to a pin 604, which is used to fix the rotating plate 602 and the mounting plate 603. The pin 604 slides through the interior of the rotating plate 602 and the mounting plate 603. The pin 604, which passes through the mounting bracket 601, the rotating plate 602 and the mounting plate 603, can firmly fix the three and prevent the mounting plate 603 from rotating during the die-cutting process. The mounting plate 603 is provided with two support plates 605 on its exterior. Bolts 606 are threaded through the interior of both support plates 605. One end of the bolts 606 is fixedly connected to a rubber post 607. The rubber post 607 can avoid damaging the surface of the cardboard when fixing it. At the same time, it has a certain friction to enhance the fixing effect of the cardboard and prevent the cardboard from sliding. The bolts 606 move precisely within the support plates 605, thereby adjusting the contact pressure between the rubber post 607 and the cardboard.

[0019] It should be noted that when adjusting the pressure of the die-cutting blade of this carton die-cutting machine, first rotate the nut 505, then the nut 505 abuts against the blade holder 3, causing the upper die base 502 to move, and then the spring 503 moves accordingly, causing the scale rod 506 to shift relative to the blade holder 3. Then observe the shift of the scale rod 506 to precisely adjust the pressure.

[0020] When die-cutting cardboard, first hold the handle of the rotating plate 602 and rotate it, which will drive the mounting plate 603 to rotate and lift the mounting plate 603. Then place the cardboard to be die-cut on the lower die base 1. Then reverse the above steps to align the mounting plate 603 with the hole of the mounting bracket 601. Then insert the pin 604 to fix the mounting plate 603. Then adjust the bolt 606 so that the rubber post 607 contacts the cardboard. Then repeat the above steps to fix the cardboard on the lower die base 1 and die-cut it.

[0021] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
