The transmission belt 41 is sleeved on all the transmission rollers 42, and the transmission belt 41 is in a taut state. After the rotating power source drives one of the transmission rollers 42 to rotate, it will drive the transmission belt 41 to start rotating around all the transmission rollers 42. The base cloth to be printed is placed on the upper end surface of the transmission belt 41, and the transmission belt 41 will drive the base cloth to be transmitted to one side.

[0025] The sizing device 2 includes a sizing bracket 21, a first sizing mechanism 5 and a second sizing mechanism 6. The direction in which the base cloth enters the frame 1 is the front side, and the direction in which the base cloth is transported is the rear side. The first sizing mechanism 5 is rotatably connected to the front side of the sizing bracket 21, and the second sizing mechanism 6 is rotatably connected to the rear side of the sizing bracket 21.

[0026] The first sizing mechanism 5 includes a round screen 51, a slurry delivery pipe 52, two linear power sources 53, two support arms 54 and a power device 1. The round screen 51 is a cylindrical mesh tube. The slurry delivery pipe 52 delivers the slurry into the round screen 51. The slurry delivery pipe 52 runs through both ends of the round screen 51 and is rotatably connected to the round screen 51. The power device 1 is a component or mechanism that can provide rotational power, such as a motor. The power device 1 in this design is a combination of a servo motor and a gear. A gear is provided on the output shaft of the servo motor, and a gear is also provided at the end of the round screen 51. The two gears are meshed, and the servo motor drives the round screen 51 to rotate through the gear. The gear here can also be replaced by a synchronous belt.

[0027] A support opening in the shape of a concave arc is provided at one end of the support arm 54, and the opening of the support opening faces upward. The slurry delivery pipes 52 at both ends of the round net 51 are respectively placed on the support openings of the two support arms 54. The support openings will not affect the rotation of the slurry delivery pipes 52. In order to prevent the slurry delivery pipes 52 from moving out of the support openings, a locking knife 55 is also provided on the support arm 54, and one end of the locking knife 55 is in the shape of an arc, and the arc-shaped end of the locking knife 55 is against the side wall of the slurry delivery pipe 52.

The magnetic bar 57 and the scraper plate 58 are located inside the round screen 51. The electromagnetic table 56 is fixed on the sizing bracket 21 and is located below the base fabric. When the electromagnetic table 56 is energized, a magnetic field is generated, which generates a downward magnetic force on the magnetic bar 57, so that the slurry cannot pass through the position where the magnetic bar 57 and the scraper plate 58 are located, so that the slurry can pass through the round screen 51 and be printed on the base fabric.

[0030] The second sizing mechanism 6 includes an upper pressing roller 61 and a lower pressing roller 62, both of which are rotatably connected to the sizing bracket 21, and the lower pressing roller 62 is located directly below the upper pressing roller 61. One end of the upper pressing roller 61 and the lower pressing roller 62 are connected to a motor. After the round screen 51 is sizing, the slurry that cannot be squeezed is squeezed by the upper pressing roller 61 and the lower pressing roller 62. By changing the size of the upper pressing roller 61 and the lower pressing roller 62, or adjusting the distance between the two pressing rollers, the upper pressing roller 61 and the lower pressing roller 62 that can achieve different pressures can be obtained. In this way, the matching sizing thickness can be applied according to the different types of base fabrics, thereby achieving the best sizing effect.

The motor is fixed on the frame 1, and the output shaft of the motor is connected to one of the reciprocating power rollers 32. When the motor is started, it can drive one of the reciprocating power rollers 32 to rotate, so that the reciprocating transmission belt 33 drives the support platform 31 to move, and the support platform 31 drives the sizing device 2 to move, so that the sizing device 2 can perform sizing.

[0034] At the front side of the sizing device 2, a base cloth conveying device 7 for transmitting the base cloth is provided. At the rear side of the sizing device 2, a digital longitudinal scanning unit 8 for scanning the printing is provided. The digital longitudinal scanning unit 8 is also fixed on the frame 1. After the base cloth is sizing, it needs to enter the digital longitudinal scanning unit 8 for printing.

[0035] Working principle:

[0036] When the base fabric and the conveyor belt 41 are stationary in the horizontal direction, the digital longitudinal scanning unit 8 reciprocates in the longitudinal direction to digitally print the base fabric. The linear speed generated by the rotation of the round screen 51 and the two pressure rollers is the same as the moving speed of the reciprocating motion device 3. The reciprocating motion device 3 drives the sizing device 2 to move in the opposite direction when the conveying device 4 transmits the base fabric, so that the first sizing mechanism 5 and the second sizing mechanism 6 sizing the base fabric.

[0037] When the base fabric and the conveyor belt 41 move laterally, the digital longitudinal scanning unit 8 stops scanning and printing, the rotary screen 51 and the two pressure rollers continue to sizing at the same speed, and the moving speed of the reciprocating device 3 is the sum of the linear speed of the rotary screen 51 when rotating and the speed at which the base fabric is driven by the conveyor 4. The moving direction of the sizing device 2 driven by the reciprocating device 3 is the same as the moving direction of the base fabric.

[0038] The rotary screen 51 is sizing the base fabric when the base fabric is stationary or moving, maintaining the sizing continuity, thereby ensuring that the sizing material is evenly and uninterruptedly applied to the base fabric, avoiding the plate-jointing marks caused by each sizing due to the intermittent movement of the conveyor belt 41.
