[0002] Laminated polyester fabric is a polyester (polyester fiber) fabric with a special surface treatment and a thin film. This film can be polyurethane, polyester or other synthetic resin materials to increase the functionality and performance characteristics of the fabric. Some laminated polyester fabrics require some special patterns, but the fabrics also need to be dyed. In order to protect the special pattern areas of the laminated polyester fabric from the influence of dyes or pigments during the dyeing process, it is usually necessary to perform wax-like printing on some special pattern areas of the fabric.

[0027] The inner wall of the fixed cover 2 is fixedly connected with a dryer 5, a replacement port is opened on one side of the fixed cover 2 close to the sliding through hole 454, a cabinet door 6 is arranged in the replacement port, the outer wall of the fixed cover 2 is fixedly connected with a PLC controller 7, the PLC controller 7 is connected with the first motor 31 and the electric telescopic rod 41 by electrical signals to form a start-stop circuit, and the printed imitation wax can be evenly dried through the dryer 5.

[0028] The working principle of the present invention is as follows: First, the coated polyester fabric is passed through the space between the first active conveying roller 33 and the first driven conveying roller 34 , below the dryer 5 , and between the second active conveying roller 36 and the second driven conveying roller 37 in sequence.

[0029] The first motor 31 is started, and the first rotating rod 32 is driven to rotate by the first motor 31, and the first active conveying roller 33 is further driven to rotate, and then the other first rotating rod 32 is driven to rotate by the gear pair, and then the first driven conveying roller 34 is driven to rotate, and then the second rotating rod 35 is driven to rotate by the belt transmission structure, and then the second active conveying roller 36 is driven to rotate, and then the other second rotating rod 35 is driven to rotate by the gear pair, and then the second driven conveying roller 37 is driven to rotate, and the coated polyester fabric is conveyed by the mutual cooperation of the first active conveying roller 33 and the first driven conveying roller 34 and the second active conveying roller 36 and the second driven conveying roller 37.

[0030] Since the PLC controller 7 is connected with the first motor 31 and the electric telescopic rod 41 by electrical signals to form a start-stop circuit, the spacing of the pattern required for printing on the coated polyester fabric is input into the PLC controller 7. Therefore, after the coated polyester fabric moves a certain distance (the distance is the distance required for printing the pattern on the coated polyester fabric), the PLC controller 7 controls the first motor 31 to stop conveying the fabric, and then starts the electric telescopic rod 41. The printing cover 42 is driven downward by the electric telescopic rod 41, and the support frame 4411 is first contacted with the fabric. As the electric telescopic rod 41 is continuously extended, the support frame 4411 is moved into the telescopic groove 4410 in the printing cover 42. When it is completely moved into the telescopic groove 4410, the second conductive plate 444 in the telescopic groove 4410 is in contact with the first conductive plate 4412 at the top of the support frame 4411. Since the first conductive plate 4412 and the second conductive plate 444 are in contact with the normally closed solenoid valve 449 and the second motor 4 41 is electrically connected to form a coating circuit, so the normally closed solenoid valve 449 and the second motor 441 are energized to open the normally closed solenoid valve 449, and then the imitation wax liquid is discharged onto the pattern plate 43 through the liquid outlet pipe 448. At the same time, the second motor 441 drives the reciprocating screw rod 442 to rotate. Since the sliding groove 445 limits the moving block 443, the moving block 443 can drive the coating plate 446 to reciprocate on the pattern plate 43 on the surface of the reciprocating screw rod 442, so that the imitation wax liquid can be evenly coated in the pattern groove in the pattern plate 43. When the coating is completed (the coating completion time is the time required for printing the pattern plate 43 by pre-testing), the electric telescopic rod 41 is controlled by the PLC controller 7 to drive the printing cover 42 to reset. During the resetting process of the printing cover 42, the support frame 4411 is reset by the first spring 4413, so that the first conductive plate 4412 and the second conductive plate 444 will no longer contact, and the second motor 441 and the normally closed solenoid valve 449 are powered off and closed.

[0031] When the electric telescopic rod 41 drives the printing cover 42 to reset, the liquid inlet pipe 469 on the top of the printing cover 42 will be inserted into the discharge pipe 465 first, and then the fixed ring 4610 will be inserted into the annular groove 466. As the printing cover 42 moves upward, it will slowly squeeze the movable ring 467, further driving the push rod 468 to move upward, and the fixed plate 464 and the sealing plug 463 are driven upward by the push rod 468, so that the imitation wax liquid flows into the liquid inlet pipe 469 through the discharge pipe 465, and finally flows into the space above the special-shaped plate 447.

[0032] When the pattern plate 43 needs to be replaced, first open the cabinet door 6, then cut off the power to the electromagnet 451. After the power is cut off, the electromagnet 451 will no longer adsorb the permanent magnet block 452 in the pattern plate 43, causing the pattern plate 43 to fall. Then put the new pattern plate 43 into the bottom of the printing cover 42 from under the fixed cover 2. After the placement is completed, the electromagnet 451 is energized to fix the pattern plate 43, and then the anti-slip plate 458 is no longer in contact with the outer wall of the printing cover 42 by tightening the bolt 457. Then, the connecting plate 455 is pulled to move the special-shaped plate 447, and the storage space above the special-shaped plate 447 is adjusted to make the adjusted storage space suitable for the newly replaced pattern plate 43. When the adjustment is completed, the bolt 457 is turned to make the anti-slip plate 458 contact with the printing cover 42 to fix the special-shaped plate 447.
