Description

[0002] The contents in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] At present, digital inkjet printing has been widely used in the digital anti-printing manufacturing industry. Since digital inkjet printing is a non-contact printing, in order to ensure the accuracy and quality of subsequent inkjet printing and prevent the wrinkled part from scraping the inkjet nozzle, it is necessary to require the textiles to be evenly spread and not wrinkle during the inkjet process.

[0004] In actual use, workers are usually required to flatten the textile fabrics on the work surface before the printing step. As the working time increases, this brings certain work pressure and burden to the workers. At the same time, for textile fabrics of different widths and processes, the required flattening methods are also different, which further increases the work difficulties of the workers. In some digital inkjet printing processes, the temperature of the working environment needs to be at a higher level. Under long-term work, it also brings serious burden to the workers' bodies. In addition, since inkjet printing requires a certain degree of precision, workers are inevitably prone to work errors under high-intensity labor conditions, which also seriously reduces the efficiency and quality of textile fabric production.

When the key is stuck in the positioning slot, the position of the driving part in the connecting hole is limited. At this time, the limiting piece is completely disengaged from the limiting hole, and the staff disassembles the printed platen.

2. A cloth pressing mechanism according to claim 1, characterized in that: The end of the limiter away from the mounting hole is provided with a chamfer, and inclined guide plates are respectively provided on both sides of the top notch of the slide groove. The bottom spacing of the two guide plates is smaller than the top spacing, and the inclination angle of the guide plate is adapted to the inclination angle of the chamfer of the limiter.

3. The cloth pressing mechanism according to claim 1, characterized in that: The driving assembly includes a screw and a driving shaft. A guide groove is opened on the mounting table along the length direction of the worktable plate. Two guide blocks are arranged in the guide groove. The guide blocks are fixedly connected to the splint. The screw is rotatably arranged in the guide groove along the length direction of the guide groove. The two guide blocks are threadedly sleeved on both ends of the screw. The driving shaft is rotatably arranged on the mounting table, and the driving shaft and the screw are transmission-connected.

4. The cloth pressing mechanism according to claim 1, characterized in that: Two strip blocks are provided on the side walls of the printing platen, and the two strip blocks are respectively provided at both ends of the printing platen. A connecting rod is rotatably provided on the strip block, and a stretching plate is rotatably provided on the side of the connecting rod away from the strip block. The bottom of the stretching plate is used to contact the fabric. A torsion spring is provided on the strip block, and the torsion spring is used to drive the connecting rod on the strip block to deflect downward. A limit rod is provided on the strip block, and the limit rod is used to abut against the lower side wall of the connecting rod to limit the deflection angle of the connecting rod. A connecting groove is provided on the side wall of the printed platen in a vertical direction, a connecting block is slidably provided in the connecting groove, the connecting block is fixedly connected to the strip block, a fourth elastic member is provided in the connecting groove, the fourth elastic member is used to drive the strip block to move downward, and the elastic modulus of the fourth elastic member is greater than the elastic modulus of the torsion spring; As the printing platen descends, the bottom of the stretching plate contacts the cloth. As the printing platen further descends, the stretching plate moves in a vertically upward direction, thereby stretching the cloth around the printing platen.

5. A cloth pressing method using a cloth pressing mechanism according to any one of claims 1 to 4, characterized in that: The following steps are involved: S1. Stretch the fabric flat on the workbench and select the corresponding printing plate according to processing needs; S2. Drive the end of the printed platen to slide into the slide groove on the connecting portion through the guide plate. When the mounting hole and the limiting hole are coaxial, the limiting member is inserted into the limiting hole to position the printed platen on the mounting portion. S3, placing the end of the printed platen away from the mounting portion on the abutment table, rotating the drive shaft so that the clamping plates on both sides abut against the ends of the printed platen, and clamping the printed platen on the abutment table; S4. The deflection angle of the connecting rod is limited by the limiting rod, and the bottom of the stretching plate is brought into contact with the fabric on the workbench; S5. Start the driving member to drive the mounting portion to move to a designated position on the mounting frame, press and flatten the textile fabric, and perform printing through the inkjet printing device.
