The synchronous wheel 65 is connected to the rotating wheel 64 by a belt.

[0041] Combined with the attached Figure 8As shown, as a preferred embodiment, grooves 521 are provided at both ends of the surface of the limit rod 52. A return spring 522 is connected inside the groove 521. Internal threads are provided on the inner wall surface of the groove 521.

A dust suction cylinder 31 is fixedly embedded in the fixing plate 3. The bottoms of the two dust suction cylinders 31 are connected with a dust suction cover 32.

[0042] Combined with the attached Figure 6 As shown, as a preferred embodiment, an installation groove 73 is provided on the side surface of the limit pressing rod 7. Limit posts 74 are provided on both sides of the installation groove 73. The cleaning soft brush 72 is slidably arranged in the installation groove 73 and is movably sleeved on the limit posts 74. The limit posts 74 and the installation groove 73 are used for the installation and limit sliding of the cleaning soft brush 72.

[0043] Combined with the attached Figure 1 to the attached Figure 8 It should be noted that the stamping die structure includes a stamping die, and the stamping die can be reciprocally driven by a hydraulic cylinder. The type of the stamping die is installed and used before implementation; in addition, the first gear 47 and the worm 63 can be driven by an external driving device. The driving device includes a servo motor, and the model of the servo motor is YCT160. The rotation speed and rotation time of the servo motor can be set before implementation. The main shafts of the servo motor and the first gear 47 are both connected with spiral bevel gears to achieve driving, and selection and installation are carried out before implementation. Among them, the model of the permanent magnet synchronous servo motor 54 is S18-130-416T0A30-305G, and the rotation speed and rotation time can be set to achieve the positioning of the blank surface of the printed product.

[0044] During overall use: When the winding and unwinding roller 41 and the printed product are installed, according to the size specification of the printed product, start the servo motor, drive the worm 63 to rotate by the servo motor, and make the first worm gear 61, the second worm gear 62, the two main ball screws 53, the rotating wheel 64, the synchronous wheel 65 and the auxiliary ball screw 510 rotate synchronously under the action of the worm 63. Then the main ball screw 53 precisely adjusts the distance between the first sliding seat 55 and the second sliding seat 56. When the first sliding seat 55 and the second sliding seat 56 slide and adjust, the stop rod 57 and the anti-deviation guiding and pressing wheel 58 are adjusted synchronously, while the auxiliary ball screw 510 precisely adjusts the distance between the first adjusting block 59 and the second adjusting block 511, so as to be applicable to the limit guiding of printed products of different widths.

[0045] When the printed matter is being transported, the printed matter passes through the port of the limit frame rod 52. First, the cleaning soft brush 72 cleans the surface of the printed matter, initially removing the fluff and dust that may adhere. Then, the suction fan 33 and the discharge fan 34 in the suction cylinder 31 provide power. The suction fan 33 sucks in the fluff and dust, which is filtered by the air filter element 351 inside the filter 35 and then discharged by the discharge fan 34, removing the attachment of impurities and dust, thus ensuring the printing quality.

[0046] After processing, the printed matter is introduced from the incoming and outgoing slot 21 on one side of the impression chamber 2. At this time, the printed matter to be printed is limited by the two side stop rods 57. At the same time, the edge of the printed matter to be printed is pressed by the anti-offset guiding and pressing wheels 58, which can prevent offset during imprinting. Then, after starting the hydraulic cylinder, the hydraulic cylinder drives the imprinting die to descend in height, making the imprinting die contact the bearing die 22 to achieve the imprinting of the texture. When one imprinting operation is completed, the hydraulic cylinder drives the imprinting die back to its original position. At this time, the permanent magnet synchronous servo motor 54 provides power, and the two anti-offset guiding and pressing wheels 58 and the connecting rod press the edge of the printed matter to be printed for guiding, completing the imprinting operation.

The winding and unwinding mechanism 4 includes two base plates 42 connected to the side of the machine body 1, a number of guide rollers 43 connected within the two base plates 42, mounting groove plates 44 connected to the inner wall surfaces of the two base plates 42, sliders 45 slidably arranged within the mounting groove plates 44, a winding and unwinding roller 41 rotatably connected between the two sliders 45, driving guide wheels 46 rotatably connected within each base plate 42 and located on both sides of the mounting groove plate 44 respectively, and gears one 47 and gears two 48 rotatably connected to both sides of the base plate 42 and meshing with each other. Each gear one 47 and gear two 48 are respectively connected to the two driving guide wheels 46.

[0049] Combined with the attached Figure 5 As shown in the figure, as a preferred implementation manner, annular grooves 411 for cooperating with the rotation of the driving guide wheels 46 are provided at both ends of the winding and unwinding roller 41. A set of fixed-distance limiting members are provided on the winding and unwinding roller 41. The fixed-distance limiting members are sleeved on the winding and unwinding roller 41 through fastening screws, which are used for limiting the printed matter during winding and unwinding to prevent offset. The driving guide wheels 46 and the anti-offset guiding and pressing wheels 58 are both made of rubber material, and the rubber material is used to increase the friction force and prevent slipping.

[0050] Combined with the attached Figure 6As shown, as a preferred embodiment, the retracting and extending mechanism 4 further includes a connecting rod assembly 49 for synchronously driving the cleaning soft brush 72. The connecting rod assembly 49 includes a U-shaped rod 491 mounted on two base plates 42, mounting cylinder barrels 492 connected to the outer wall surfaces on both sides of the U-shaped rod 491, push rods 493 movably arranged in the mounting cylinder barrels 492, two swing plates 494 rotatably connected to the outside of the U-shaped rod 491 and respectively rotatably connected to the ends of the two push rods 493, a mounting member 495 connected to the outside of the U-shaped rod 491, and a compression spring 496 sleeved on the mounting member 495. The other end of each push rod 493 is rotatably connected to the cleaning soft brush 72. A pressing cylinder 497 is rotatably connected to each swing plate 494. Each pressing cylinder 497 is respectively sleeved on the mounting member 495 and is connected to the side surface of the compression spring 496. An eccentric block 498 is rotatably provided on each base plate 42. One eccentric block 498 is sleeved on the rotating shaft of the first gear 47, and the other eccentric block 498 is correspondingly connected to the driving guide wheel 46;

[0051] During installation: The staff slides the sliders 45 on both sides of the retracting and extending roller 41 into the installation groove plate 44, and makes the driving guide wheel 46 stuck in the annular groove 411 at both ends of the retracting and extending roller 41, which can realize the convenient installation and removal of the retracting and extending roller 41 and the printed matter to be printed, improve the imprinting efficiency, and then pass through between several guiding rollers 43 in sequence, and be introduced from the printed matter inlet and outlet groove 21 on one side of the imprinting chamber 2, pass through the anti-deviation mechanism 5, and be exported from the printed matter inlet and outlet groove 21 on the other side, and be connected to the equipment in the next process;

[0052] Then start the servo motor to drive the spiral bevel gear, and drive the first gear 47 and the second gear 48 on one side to rotate synchronously. Then, as the two driving guide wheels 46 rotate, the retracting and extending roller 41 is driven to convey the printed matter to be printed. When each second gear 48 rotates, the eccentric block 498 on the second gear 48 synchronously contacts and presses one side of the swing plate 494, so that the pressing cylinder 497 slides on the mounting member 495 and compresses the compression spring 496 to cause the compression spring 496 to be deformed by extrusion and generate a resilience force. At this time, using the lever principle, the push rod 493 on the other side of the swing plate 494 pulls the cleaning soft brush 72 to initially clean the fluff and dust adhered to the surface of the conveyed printed matter. When the eccentric block 498 leaves the swing plate 494, the swing plate 494 returns to its original position under the action of the resilience force of the compression spring 496. Under the reciprocating and uniform motion, the cleaning soft brush 72 reciprocally cleans the fluff and dust adhered to the surface of the printed matter, with a better effect, thereby improving the printing quality.

[0053] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
