[0029] The clamping unit includes an electric push rod 19, a clamping plate 10, an electric push rod 213, a stopper 14 and an air pipe 15; an electric push rod 19 is bolted to the front and rear sides of the support plate 8; the telescopic part of each electric push rod 19 is fixedly connected to a clamping plate 10; each clamping plate 10 is fixedly connected and connected to an air pipe 15; an electric push rod 213 is bolted to the left and right sides of the support plate 8; the telescopic part of each electric push rod 213 is fixedly connected to a stopper 14.

[0030] The clamping plate 10 is provided with a card slot 10a. By providing the card slot 10a on the clamping plate 10, the edge of the cardboard box will not flip up when it is clamped by the two clamping plates 10, thereby avoiding the problem that the cardboard box is bent when the carton board is fixed, affecting the subsequent cutting work.

[0031] It also includes a cylindrical roller 11; the cylindrical roller 11 is installed in the middle of the cutting roller 5, and the width of the cylindrical roller 11 is the same as the width of the concave area in the middle of the support plate 8.

[0032] A double-helical scraper strip can also be provided on the surface of the cylindrical roller 11, which pushes the debris toward the front and rear discharge grooves 8b respectively, so that the debris is gathered together and falls into the collection frame 12 through the discharge groove 8b more quickly to be collected.

[0033] It also includes a baffle 16 and an air pipe 17; a baffle 16 is fixedly connected to the inner side of the shell 1, the baffle 16 is curved, and an inclined portion 16c inclined to the left is arranged on the upper part of the baffle 16, and the baffle 16 is located on the right side of the printing roller 3; an air pipe 17 is fixedly connected to the upper part of the shell 1, and the air pipe 17 is connected to the inside of the shell 1, and the upper part of the baffle 16 is located in the middle of the air pipe 17, which is used to divert the air ejected from the air pipe 17.

[0034] Two top sheets 16a distributed front and back are fixedly connected to the right side of the baffle 16, and the top sheets 16a are used to push away the residual material to prevent the residual material from falling on the surface of the carton board and affecting the subsequent printing work.

[0035] The baffle plate 16 is provided with two guide plates 16b, through which the air ejected from the air pipe 2 17 is guided to the front and rear sides.

[0036] The second baffle 18 is also included; the second baffle 18 is fixedly connected to the inner side of the housing 1 , the second baffle 18 is located to the upper right of the first baffle 16 , and the length of the second baffle 18 is greater than the length of the first baffle 16 .

[0037] The upper part of the baffle 16 is provided with an inclined portion 16c, through which the air sprayed from the air pipe 2 17 is directed to the surface of the carton board, so that the printed surface is dried quickly.

[0038] The second guide piece 22 is fixedly connected to the inner side of the housing 1, and the second guide piece 22 cooperates with the inclined portion 16c to guide the air ejected from the air pipe 17 to the printing position of the carton board, so that the printed carton board can be dried quickly.

[0039] Here is how the above example works:

[0040] When in use, connect the motor 1 2, the motor 2 4, the electric guide rail 6, the electric slider 7, the electric push rod 1 9, the electric push rod 2 13 and the electric push rod 3 20 to the power supply, and connect the air pipe 1 15 and the air pipe 2 17 to the external pump, then control the electric push rod 2 13 on the right side of the pallet 8 to drive the stopper 14 to move downward, so that the stopper 14 will not block the carton board, and then the carton board to be processed is transferred to the pallet 8 through the external conveying device. If the cardboard is simply placed on the pallet 8, it will be cut and printed. During the brushing operation, the carton board is easy to deviate, resulting in the position deviation of cutting and printing. Therefore, when the carton board is transported to the pallet 8, the block 14 on the left side of the pallet 8 presses against the left side of the carton board, and then the electric push rod 13 on the right side of the pallet 8 is controlled to drive the block 14 to move upward and reset, so that the two blocks 14 block the carton board, and control the two electric push rods 19 to push the corresponding clamping plates 10 towards each other, so that the two clamping plates 10 clamp the front and rear sides of the carton board, and through the cooperation of the two blocks 14 and the two clamping plates 10, The carton board is fixed so that the carton board will not deviate during subsequent cutting and printing, which is conducive to ensuring the normal subsequent cutting and printing. At the same time, by setting a card slot 10a on the clamping plate 10, the edge of the cardboard box will not flip up when it is clamped by the two clamping plates 10, thereby avoiding the problem that the cardboard box is bent when the carton board is fixed, which affects the subsequent cutting work. Then the electric slider 7 is controlled to drive the support plate 8, the electric push rod 3 20 and the creasing knife 21 to move to the left along the electric guide rail 6, so that the support plate 8 drives The carton board passes through the cutting roller 5, and the control motor 24 drives the cutting roller 5 to rotate, so that the cutting roller 5 cuts off the excess material at the edge of the carton board. Since the cutting roller 5 cuts the excess material at the edge of the carton board, debris will be generated, resulting in a large amount of debris remaining on the surface of the carton board, affecting the subsequent printing work. Therefore, when the cutting roller 5 cuts the excess material at the edge of the carton board, the edge of the cutting roller 5 will be located in the discharge groove 8a, so that the debris generated during the cutting process of the cutting roller 5 is discharged from the discharge groove 8a and falls into the collection frame 12.

[0041] After the residual material is cut off, the residual material loses connection with the carton board body, causing the residual material and the carton board body to be staggered and separated, and then the carton board body cannot be clamped, resulting in the subsequent printing process. The carton board position is easily offset and the printing position is offset. Therefore, when the cutting roller 5 cuts the carton board, the cutting roller 5 will drive the cylindrical roller 11 to rotate synchronously, so that the cylindrical roller 11 squeezes the cut carton board downward, so that the cut carton board is pressed into the recessed area on the support plate 8 by the cylindrical roller 11, so that the recessed area jams the carton board body, and when the carton board is pressed into the recessed area on the support plate 8, the carton board body can still be restricted by the two blocks 14, thereby ensuring the stability of the carton board and avoiding the carton board from being offset, which causes the problem of printing position offset.

[0042] When the carton board body is completely inserted into the recessed area, the residual material loses the connection with the carton board body. The vibration generated during the subsequent movement of the support plate 8 can easily cause the residual material to fall onto the surface of the carton board body, affecting the subsequent printing work. Therefore, when the support plate 8 drives the carton board to pass through the cutting roller 5 to cut the residual material, the external pump is controlled to suck air through the air pipe 15, so that the suction hole in the card slot 10a generates negative pressure to absorb the residual material, so that the residual material remains stable during the cutting process, avoiding the problem that the residual material loses the connection with the carton board body and falls onto the surface of the carton board body, thereby affecting the subsequent printing work.

[0043] At the same time, when the support plate 8 drives the three electric push rods 20 and the corresponding creasing knives 21 to pass under the cutting roller 5 in sequence, the three electric push rods 20 are controlled to push the corresponding creasing knives 21 to move upward, so that the cylindrical roller 11 and the creasing knife 21 cooperate with each other to press creases on the surface of the carton board, which is convenient for the subsequent assembly of the box.

[0044] When the carton board residue is cut, some debris generated by the cutting remains on the surface of the carton board. Therefore, when the carton board is completely moved to the left side of the cutting roller 5 and the residue at the edge of the carton board is cut, the electric slider 7 continues to drive the cut carton board to move to the left through the supporting plate 8. At the same time, the external pump machine controlling the air pipe 15 cancels the suction force on the residue, so that when the residue contacts the top sheet 16a, the residue will be supported by the top sheet 16a and stop moving to the left. As the supporting plate 8 continues to move to the left, the residue falls into the collecting frame 12. While the residue is supported by the top sheet 16a, the external pump machine controlling the air pipe 17 pumps in air, so that the air is ejected from the air pipe 17. The ejected air will be sprayed on the surface of the baffle 16 and move along the baffle 1 6 surface is blown to the surface of the carton board, so that the debris on the surface of the carton board is blown to the right, and falls along the surface of the carton board to be collected in the collection frame 12, so as to prevent the debris from remaining on the surface of the carton board, resulting in the debris adhering to the printing roller 3 when the subsequent printing roller 3 prints on the surface of the cardboard box, affecting the quality after printing. At the same time, a guide piece 16b is arranged on the baffle piece 16, so that part of the air ejected from the air pipe 17 will be guided by the guide piece 16b to the front and rear sides, so that the air guided by the guide piece 16b will quickly blow the debris on the surface of the carton board close to the discharge slot 2 8b to the direction of the discharge slot 2 8b, so that the debris falls into the collection frame 12 through the discharge slot 2 8b and is collected, and then, as the electric slider 7 continues to drive the carton board to move to the left through the support plate 8 The carton board will contact with the printing roller 3, so that the carton board will be printed by the printing roller 3. However, due to the large number of carton boards to be printed, they need to be quickly stacked together after printing, and waiting for the printed pattern to dry will waste a long time. Therefore, by controlling the thickness of the coating printed on the surface of the carton board by the printing roller 3, the thickness of the printed coating is thinner, so that the coating can be dried quickly. At the same time, the air ejected from the air pipe 17 will be diverted by the baffle 16, so that part of the air ejected from the air pipe 17 flows to the right along the baffle 16, and part of the air flows to the right along the inclined portion 16c on the baffle 16. At the same time, the rightward flowing air is restricted by the guide plate 22, so that the rightward flowing air is guided to the surface of the carton board during printing. The air is blown to the printed surface of the carton board to speed up the drying speed of the printed pattern. At the same time, in order to avoid a large airflow from the air pipe 17, the blowing air will blow away the printed coating. The velocity of the airflow from the air pipe 17 is reduced, and the velocity of the airflow from the air pipe 17 is slowed down, thereby preventing the printed coating from being blown away. However, due to the slowdown in the velocity of the airflow from the air pipe 17, the air sprayed from the air pipe 17 has a poor effect on blowing debris on the surface of the carton board. Therefore, a baffle 18 is provided, and the baffle 18 is located above the baffle 16. The air flow space is compressed by the baffles 16 and 18, so that the air sprayed from the air pipe 17 is more concentrated, which is beneficial to ensure the blowing effect of the airflow on the debris on the surface of the carton board.

[0045] Embodiment 2: Based on embodiment 1, Figure 6-Figure 8 As shown, a rotating plate 19 is also included; each stopper 14 is provided with two protrusions 14a distributed front to back; and the supporting plate 8 is rotatably connected to the two rotating plates 19 via a torsion spring.

[0046] Here is how the above example works:

[0047] When the electric slider 7 drives the carton board through the printing roller 3 through the support plate 8, the carton board is printed and needs to be taken out. Since the carton board needs a relatively stable state when printing, after being squeezed by the cylindrical roller 11 and the printing roller 3, the carton board is stably stuck in the concave area in the middle of the support plate 8, but the carton board in this state is not easy to take out. Therefore, after the carton board passes the printing roller 3, the electric push rod 3 20 drives the creasing knife 21 to move back and forth up and down, so that the creasing knife 21 pushes the middle part of the carton board upward, but the left and right parts of the carton board are still in the concave area. If the electric push rod 3 20 is directly controlled to drive the creasing knife 21 to push the carton board upward, the middle part of the carton board will bulge upward, causing the carton board to bend and deform, affecting the quality of the carton. Therefore, when the electric push rod 3 20 drives the creasing knife 21 to push the carton board upward, the two electric push rods 2 13 are controlled to drive the corresponding The stopper 14 moves downward, so that the protrusion 14a will drive the rotating plate 19 to rotate downward, and then the upwardly tilted end of the rotating plate 19 will push up the left and right edges of the carton board, so that the carton board as a whole is lifted up at the same time, avoiding the deformation of the carton board and affecting the quality problem. When the carton board as a whole is lifted upward and leaves the recessed area in the middle of the support plate 8, the protrusion 14a continues to drive the rotating plate 19 to rotate downward, so that the left and right edges of the carton board are in a suspended state, which is convenient for the external taking-away device to quickly take away the printed carton board. When the external taking-away device takes away the carton board, the electric push rod three 20 is controlled to drive the creasing knife 21 to move downward and reset, and the two electric push rods 2 13 are controlled to drive the corresponding stopper 14 to move upward and reset. The rotating plate 19 is rotated and reset by the torsion spring, and then the support plate 8 is controlled to drive the relevant parts to move to the right and reset, so as to cut and print the subsequent carton boards.

[0048] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
