[0014] A processing technology for a sunflower round cardboard processing line includes the following steps: Step S10, the original board loading process, is to place the original boards on the cardboard loading mechanism at equal intervals manually or by machine, and then the cardboard loading mechanism transports the original boards to the bottom of a corresponding set of transfer mechanisms, and then the Z-axis displacement assembly moves the adsorption assembly to the top of the original board, and the adsorption assembly starts working to adsorb the original board, and then the Z-axis displacement assembly resets the original board, and then the X-axis displacement assembly and the Z-axis displacement assembly transfer the original board to the top of the carrying mechanism, and the adsorption assembly is closed, so that the original board falls onto the carrying mechanism; Step S20, cardboard positioning process: after the original board falls onto the carrying mechanism, the drive motor is started to drive the rotating assembly to rotate, that is, to drive the four positioning assemblies to move toward the center at the same time, thereby positioning the original board at the center; Step S30, cardboard cutting process: after the original board is positioned, the pressing assembly is started to descend until it presses the original board, and then the pressing assembly continues to descend. During this process, a circular hole is cut out of the original board at the bottom of the pressing assembly. At the same time, the upper half of the pressing assembly rotates, driving the circular cutting assembly to rotate and descend accordingly, completing the cutting of the outer edge of the original board. Step S40, the finished product output process, after the cardboard cutting is completed, the finished cardboard is adsorbed and transported to the cardboard delivery mechanism by the transfer mechanism located above the cardboard delivery mechanism, so that the finished cardboard is delivered.

[0015] The beneficial effects of adopting the above technical solution are: 1. This solution features fully automated production, with each mechanism and process working closely together.

Compared to traditional production methods, this greatly shortens the production cycle and increases output per unit time.

[0016] 2. This solution ensures precise cutting of the center hole and outer edge of the cardboard through the precise design of the pressing component and the circular cutting component, as well as the precise positioning of the supporting mechanism, which significantly improves the cutting accuracy and effectively reduces the defective rate. The original board is firmly fixed in the ideal position through the supporting mechanism, and the positioning accuracy can be accurate to an extremely small range, ensuring that the position of the cardboard is always stable during the cutting process, providing a solid guarantee for high-precision cutting.

[0017] 3. This solution can arbitrarily adjust the cutting angle of the outer edge of the cardboard and the cutting diameter of the cardboard, so that this production line can quickly adapt to the production needs of sunflower round cardboards of different sizes and specifications. Whether it is to meet the requirements of small customized orders for personalized size and special design, or to cope with the pursuit of high efficiency and stability in large-scale mass production, it can do it with ease, showing excellent adaptability and a wide range of applications.

[0018] 4. The improvement of the degree of automation of this solution means a significant reduction in manual operation links, which reduces labor costs while ensuring the continuity of the production process.

DETAILED DESCRIPTION

[0020] The following is a further detailed description of the specific implementation methods of the present invention through the description of embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the concept and technical solution of the present invention and to facilitate its implementation.

[0021] Example 1: Specifically, if Figures 1 to 11 As shown, a sunflower round cardboard processing line includes a processing table 1 and also includes: A cardboard feeding mechanism 2, which is arranged on one side of the processing table 1; A cardboard delivery mechanism 3, which is arranged on the other side of the processing table 1; A carrying mechanism 4, wherein the carrying mechanism 4 is rotatably connected to the processing table 1 under the action of a driving motor; The transfer mechanism 5 is provided with two groups, which are respectively installed on both sides of the top of the processing table 1; The processing mechanism 6 is installed in the middle of the processing table 1 and is located directly above the supporting mechanism 4; The processing mechanism 6 includes a fixed bracket 61 installed on the processing table 1 , a pressing component 62 installed on the fixed bracket 61 , and a ring cutting component 63 fixedly connected to the middle of the pressing component 62 .

[0022] It should be noted that the cardboard feeding mechanism 2 and the cardboard feeding mechanism 3 have the same structure, but are in opposite conveying directions. A baffle is provided on one side of the cardboard feeding mechanism 2 and the cardboard feeding mechanism 3 located on the processing table 1 to prevent the cardboard from escaping from the cardboard feeding mechanism 2 and the cardboard feeding mechanism 3. In detail, the original board is transported by the cardboard feeding mechanism (2) to the bottom of the left transfer mechanism (5), and is then grasped by the adsorption component (54) and transferred to the carrying mechanism (4) for positioning; after the processing mechanism (6) completes the cutting of the center hole and the outer edge, the right transfer mechanism (5) grasps the finished product and transfers it to the cardboard delivery mechanism (3), thus realizing full-process automated production, with each process closely connected, greatly improving production efficiency and finished product qualification rate.

[0023] The pressing assembly 62 includes a driving cylinder 621 installed in the middle of the fixed bracket 61, a connecting rod 622 connected to the output end of the driving cylinder 621, a sleeve rod 623 sleeved on the bottom end of the connecting rod 622, a pressing plate 624 fixedly connected to the bottom of the sleeve rod 623, and a circular cutter 625 installed on the bottom of the pressing plate 624. A sliding rod passes through the middle of the connecting rod 622 , a spiral sliding groove adapted to the sliding rod is opened on the inner wall of the sleeve rod 623 , and an elastic rod is installed on the inner wall of the sleeve rod 623 .

[0024] It should be noted that when work is required, the driving cylinder 621 is started to drive the connecting rod 622 to descend, that is, the sleeve rod 623 and the pressing plate 624 are driven to descend. During the descending process, the circular cutter 625 at the bottom of the pressing plate 624 first contacts the cardboard, and then continues to descend to cut the cardboard. Then the pressing plate 624 contacts the cardboard and presses the cardboard tightly on the carrying plate 412. At this time, the sleeve rod 623 cannot continue to descend, but the connecting rod 622 will continue to descend, that is, the connecting rod 622 slides downward inside the sleeve rod 623, and at this time, the sliding rod and the spiral slide groove cooperate to make the connecting rod 622 spirally descend; In addition, an annular groove for accommodating the circular cutter 625 is provided on the carrier plate 412 to prevent the circular cutter 625 from being damaged. During the descent process, the connecting rod 622 will squeeze the elastic rod, on the one hand, preventing it from contacting the bottom of the sleeve rod 623 and causing mutual damage. On the other hand, when the connecting rod 622 is reset, it provides it with a reverse elastic force to prevent it from moving upward independently and separating from the sleeve rod 623. At the same time, due to the existence of the connecting rod 622, during the normal descent process, the sleeve rod 623 is ensured to be lowered and the connecting rod 622 will not move into the sleeve rod 623. Specifically, the height to which the connecting rod 622 spirally descends is exactly the distance that the circular cutting assembly 63 rotates twice, which enables the circular cutting assembly 63 to complete the cutting of the cardboard and also enables it to return to its initial position to prevent it from affecting the loading and unloading of the cardboard.

[0025] The ring cutting assembly 63 includes an adapter ring rod 631 fixedly connected to the connecting rod 622, a Z-shaped rod 632 connected to the adapter ring rod 631 via a pin, a micro cylinder 633 installed at the bottom of the Z-shaped rod 632, and a cutter 634 slidably connected to the Z-shaped rod 632 under the drive of the micro cylinder 633; The bottom of the Z-shaped rod 632 is provided with a through slot adapted to fit the cutter 634 .

[0026] It should be noted that the spiral descent of the connecting rod 622 drives the adapter ring rod 631 and the Z-shaped rod 632 to spirally descend, thereby driving the cutter 634 to cut the cardboard in a circular manner. At the same time, the micro cylinder 633 is activated during the cutting process to make the cutter 634 reciprocate, that is, the diameter of the circular cutting reciprocates within two intervals, thereby completing the sunflower cardboard shape cutting; In detail, the adapter ring rod 631 has multiple connection holes, and the position of the Z-shaped rod 632 can be adjusted by a pin, that is, the cutting diameter can be adjusted; In addition, the cutting angle of the cutting triangle can be adjusted by simply adjusting the reciprocating speed of the micro cylinder 633, and the length between each cutting triangle can be adjusted by simply adjusting the interval time of the reciprocating motion of each group of micro cylinders 633.

[0027] The carrying mechanism 4 includes a rotating assembly 41 connected to the output end of the driving motor through a transmission chain and four sets of positioning assemblies 42 arranged along the circumference of the rotating assembly 41; The rotating assembly 41 includes a rotating shaft 411 that passes through the table top of the processing table 1 and is rotatably connected to the table top of the processing table 1, a supporting plate 412 that is rotatably connected to the rotating shaft 411, and a gear sleeve 413 that is sleeved on the upper surface of the rotating shaft 411. The bottom end of the supporting plate 412 is fixedly connected to the table top of the processing table 1 through several sets of shaft seats.

[0028] It should be noted that the drive motor drives the rotating shaft 411 to rotate through the transmission chain, that is, drives the gear sleeve 413 on its surface to rotate, that is, drives the positioning assembly 42 to work, while the carrying plate 412 does not rotate due to the role of the shaft seat, which ensures the stability of the cardboard and the smooth operation of the positioning assembly 42. In addition, since the rotating shaft 411 is arranged to pass through the table top of the processing table 1, the gear sleeve 413 is sleeved on the portion of the rotating shaft 411 located above the table top of the processing table 1.

[0029] The positioning assembly 42 includes a push plate 421 slidably connected to the carrier plate 412, a support rod 422 fixedly connected to one side of the back of the push plate 421, a connecting rod 423 fixedly connected to the other side of the back of the push plate 421, and a rack 424 mounted on the bottom of the connecting rod 423; The support rod 422 is slidably connected to the carrier plate 412 . A through slot is defined on the top of the carrier plate 412 for the connecting rod 423 to pass through. The rack 424 is meshed with the gear sleeve 413 .

[0030] It should be noted that the rotation of the gear sleeve 413 will drive the four sets of racks 424 to move inward at the same time, that is, the push plate 421 will move toward the center through the connecting rod 423, pushing the cardboard to the center, completing the positioning of the cardboard and giving it a preliminary fixation effect; In addition, when it is necessary to return, it is only necessary to flip the drive motor. The four sets of racks 424 are staggered to avoid interference with each other when moving inward at the same time.

[0031] The transfer mechanism 5 includes a side bracket 51 installed on one side of the top of the processing table 1, a Z-axis displacement component 52 installed on the side bracket 51, an X-axis displacement component 53 connected to the Z-axis displacement component 52, and an adsorption component 54 installed on the X-axis displacement component 53.

[0032] The Z-axis displacement assembly 52 includes a fixed plate 521 mounted on the side bracket 51, a rotating motor 522 mounted on the top of the fixed plate 521, a Z-axis threaded rod 523 connected to the output shaft of the rotating motor 522, slide rails 524 mounted on both sides of the Z-axis threaded rod 523, and a slider 525 threadedly connected to the Z-axis threaded rod 523. The slider 525 is slidably connected to the two sets of slide rails 524 .

[0033] It should be noted that, when working, it is only necessary to start the rotating motor 522 to drive the Z-axis threaded rod 523 to rotate, that is, to drive the slider 525 to slide on the slide rail 524. The forward and reverse rotation of the rotating motor 522 drives the slider 524 to reciprocate up and down.

[0034] The X-axis displacement assembly 53 includes a U-shaped frame 531 connected to one side of the slider 525 , an X-axis threaded rod 532 installed between two sides of the U-shaped frame 531 , and a micro motor 533 connected to one end of the X-axis threaded rod 532 .

[0035] It should be noted that, when working, it is only necessary to start the micro motor 533 to drive the X-axis threaded rod 532 to rotate, that is, to drive the air pump 541 to slide in the U-shaped frame 531 to complete the lateral movement thereof.

[0036] The adsorption assembly 54 includes an air pump 541 threadedly connected to the X-axis threaded rod 532 through a kit and an adsorption nozzle 542 connected to the output port of the air pump 541. The air pump 541 is slidably connected to the through groove opened at the bottom of the U-shaped frame 531.

[0037] It should be noted that when working, it is only necessary to start the vacuum pump 541 to suck the cardboard through the suction nozzle 542 and thus transfer it. After transferring it to the designated position, the vacuum pump can be turned off to make the cardboard fall off, completing the cardboard transfer work. Example 2

[0038] Specifically, if Figures 1 to 12 As shown, a processing technology of a sunflower round cardboard processing line includes the following steps: Step S10, the original board loading process, is to place the original boards on the paperboard loading mechanism 2 at equal intervals manually or by machine, and then transport the original boards to the bottom of a corresponding group of transfer mechanisms 5 by the paperboard loading mechanism 2. Then, the adsorption assembly 54 is moved to the top of the original board by the Z-axis displacement assembly 52, and the adsorption assembly 54 starts working to adsorb the original board. The Z-axis displacement assembly 52 is then reset, and the original board is transferred to the top of the carrier mechanism 4 by the X-axis displacement assembly 53 and the Z-axis displacement assembly 52, and the adsorption assembly 54 is closed, so that the original board falls onto the carrier mechanism 4. Step S20, cardboard positioning process: after the original board falls onto the carrying mechanism 4, the drive motor is started to drive the rotating assembly 41 to rotate, that is, to drive the four groups of positioning assemblies 42 to move toward the center at the same time, thereby positioning the original board at the center; Step S30, cardboard cutting process: after the original board is positioned, the pressing assembly 62 is started to descend until it presses the original board, and then the pressing assembly 62 continues to descend. During this process, a circular hole is cut out of the original board from the bottom of the pressing assembly 62. At the same time, the upper half of the pressing assembly 62 rotates, driving the circular cutting assembly 63 to rotate and descend accordingly, completing the cutting of the outer edge of the original board. Step S40 is a finished product output process. After the cardboard cutting is completed, the finished cardboard is adsorbed and transported to the cardboard delivery mechanism 3 by the transfer mechanism 5 located above the cardboard delivery mechanism 3, so that the finished cardboard is delivered.

[0039] It should be noted that the processing line has the advantage of fully automated production. Each mechanism and process is closely meshed like precision gears and operates in coordination. In the raw board loading link, the cardboard loading mechanism transports the raw board to the bottom of the transfer mechanism in an orderly manner at a stable rhythm according to the preset program; the transfer mechanism responds quickly, and with the help of its precise displacement control and adsorption components, it instantly grabs the raw board and places it accurately on the supporting mechanism; the supporting mechanism starts immediately, quickly and accurately positions the raw board, and makes full preparations for the cutting process; then, the pressing component and the circular cutting component of the processing mechanism cooperate tacitly to cut the cardboard efficiently; after the cutting is completed, the finished product is quickly transferred to the cardboard delivery mechanism through the transfer mechanism and the output is successfully completed; the whole process is smooth and seamless, and almost no frequent human intervention is required.

[0040] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above-mentioned concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
