Description

A device for optimizing the structure of a crimping die Technical Field

[0001] This utility model relates to the field of crimping machine technology, and more specifically, to a crimping die structure optimization device. Background Technology

[0002] With the development of the cardboard box manufacturing industry, the creasing process has become particularly important in cardboard box production. Traditional creasing uses upper and lower rollers for rolling. While this method effectively creates clear fold lines on the cardboard, it has several problems and shortcomings in practical application. First, because the upper and lower rollers are circular, the contact between the cardboard and the rollers is point contact, resulting in a small force-bearing area. When the cardboard passes over the rollers, it is instantly thinned, easily affecting the folding strength and even causing the cardboard to burst, negatively impacting the folding process. To solve this problem, the current solution is to add a humidification treatment process before creasing, but this additional process undoubtedly increases production costs. Summary of the Invention

[0003] The purpose of this invention is to provide a creasing die structure optimization device, which optimizes the creasing die structure, increases the stress area of ​​creasing, reduces the adverse effects on folding strength, and prevents cardboard from bursting. It also eliminates the need for an additional humidification process before creasing, thus saving production costs.

[0004] The embodiments of this utility model are achieved through the following technical solutions:

[0005] A creasing die structure optimization device includes an upper die body connected to a creasing machine body. The bottom surface of the upper die body is provided with an elongated creasing cutter head. Below the upper die body is a lower die body fixedly connected to the creasing machine body. A working space is formed between the upper die body and the lower die body. The front end of the creasing cutter head is located on the side of the upper die body where the cardboard enters the working space, and the tail end of the creasing cutter head is located on the side of the upper die body where the cardboard exits the working space. The top surface of the lower die body is provided with a groove that cooperates with the creasing cutter head.

[0006] In some embodiments, the wire crimping head includes a guide section, a reinforcing section, and a buffer section that are smoothly connected in sequence, wherein the guide section is the front end of the wire crimping head, and the buffer section is the tail end of the wire crimping head.

[0007] In some embodiments, the vertical cross-section of the guide segment is a right triangle with an arc-shaped hypotenuse, the cross-section of the guide segment is a trapezoid with an arc-shaped lower base, and the area of ​​the cross-section of the guide segment gradually increases along the moving direction of the cardboard.

[0027] Please refer to Figures 1-4. The main body of this embodiment is a creasing die structure optimization device, including an upper die body 2 connected to the creasing machine body 1. The bottom surface of the upper die body 2 is provided with a long strip-shaped creasing cutter head 3. The lower part of the upper die body 2 is provided with a lower die body 4 fixedly connected to the creasing machine body 1. A working space is formed between the upper die body 2 and the lower die body 4. The front end of the creasing cutter head 3 is provided on the side of the upper die body 2 where the cardboard enters the working space, and the tail end of the creasing cutter head 3 is provided on the side of the upper die body 2 where the cardboard exits the working space. The top surface of the lower die body 4 is provided with a groove 5 that cooperates with the creasing cutter head 3.

[0028] This device uses a long strip-shaped creasing head 3 to crease the cardboard. Compared with roller creasing, the stress area of ​​the cardboard is increased from a point to a line, thereby reducing the adverse effects on the folding strength and preventing the cardboard from bursting. It also eliminates the need for an additional humidification process before creasing, saving production costs.

[0029] In some embodiments, the wire pressing head 3 includes a guide section 6, a reinforcing section 7, and a buffer section 8 that are smoothly connected and integrally formed in sequence. The guide section 6 is the front end of the wire pressing head 3, and the buffer section 8 is the tail end of the wire pressing head 3.

[0030] The guide section 6 facilitates the guidance of the cardboard into the working space, the reinforcing section 7 makes the cardboard fibers at the crease more evenly arranged, and the buffer section 8 eliminates the stress concentration generated when the cardboard is folded at the crease, thus preventing the crease from bursting.

[0031] In some embodiments, the vertical cross-section of the guide segment 6 is a right triangle with an arc-shaped hypotenuse, the cross-section of the guide segment 6 is a trapezoid with an arc-shaped lower base, and the area of ​​the cross-section of the guide segment 6 gradually increases along the moving direction of the cardboard.

[0032] The cardboard enters the working space from the arc-shaped inclined edge of the guide section 6, and the cross-sectional area of ​​the guide section 6 gradually increases along the moving direction of the cardboard, thereby moving the corresponding position on the cardboard to the reinforcing section 7 and entering the creasing state.

[0033] In some embodiments, the cross-section of the reinforcing segment 7 is the same as the cross-section of the guiding segment 6, the front end of the reinforcing segment 7 is smoothly connected to the front end of the guiding segment 6, and the outer surface of the reinforcing segment 7 is covered with cross-patterns.

[0034] The reinforcing section 7 performs a creasing operation on the paperboard, and the cross-pattern covering the outer surface of the reinforcing section 7 combs and arranges the paperboard fibers at the creasing point, making them more uniform.

[0035] In some embodiments, the front end of the buffer segment 8 is smoothly connected to the rear end of the reinforcing segment 7, and the rear end of the buffer segment 8 is configured as a spoon shape with a rounded bottom surface.

[0036] The bottom surface of the buffer section 8 is rounded and spoon-shaped to smooth the creases of the cardboard, eliminating stress concentration when the cardboard is folded and preventing the creases from bursting.

[0037] In some embodiments, the upper mold body 2 is provided with a sensor array 9 consisting of multiple thin-film pressure sensors inside, and a mounting plate 10 is provided on the bottom surface of the sensor array 9, and the wire pressing head 3 is installed on the bottom of the mounting plate 10.

[0038] The sensor array 9 monitors the pressure at various points on the pressure line in real time.

[0039] In some embodiments, a pressure regulating array 11 composed of multiple piezoelectric ceramic plates is provided between the mounting plate 10 and the sensor array 9.

[0040] When the sensor array 9 detects insufficient pressure at a certain location, a voltage is applied to the piezoelectric ceramic sheet at the corresponding position of the pressure regulating array 11. The internal crystal structure of the piezoelectric ceramic sheet deforms and elongates downward, thereby lifting the corresponding position of the mounting plate and achieving pressure compensation at that position.

[0041] In some embodiments, the upper mold body 2 is detachably connected to the crimping machine body 1. The crimping machine body 1 is provided with a dovetail groove 12, and the top of the upper mold body 2 is provided with a fitting block 13 that mates with the dovetail groove 12.

[0042] This facilitates the replacement and maintenance of the crimping cutter head 3 on the upper mold body 2.

[0043] It is worth mentioning that both the sensor array 9 and the pressure regulating array 11 are electrically connected to the crimping machine body 1.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
