Description

Technical Field

[0001] The present invention belongs to the technical field of printers, and in particular relates to a flatbed printer and a method for using the same. Background Art

[0002] A flatbed printer, also known as a universal printer, is a device that can perform color photo-level printing on surfaces such as wood, glass, crystal, PVC, ABS, acrylic, metal, plastic, stone, leather, cloth and other textiles. Its printing method is inkjet printing, and there is no actual contact with the object during the printing process. Flatbed printers are not restricted by any materials. Whether it is a simple block color pattern, a full-color pattern or a pattern with transition colors, it can be printed in one go without the need for plate making, plate exposure and repeated color registration. The application field is very wide, such as the UV flatbed printer disclosed in the patent with application number CN202020144960.6, which includes a workbench with motor drive groups on both sides of the workbench, and a printing block on the motor drive group. A contraction groove is provided on the top, and a spring is provided in the contraction groove, a connecting block is provided on the spring, and a pressure plate is provided on the connecting block, the pressure plate is rotatably connected to the connecting block through a rotating shaft, and the pressure plate is elastically and telescopically connected to the workbench in the contraction groove through the connecting block and the spring, a control panel is provided on the workbench, and a storage box is provided on the workbench, and the storage box is symmetrically distributed on the workbench, a contraction groove is provided on the workbench of the UV flatbed printer, and a spring is provided in the contraction groove, and a connecting block is connected to the spring, and a pressure plate is provided on the connecting block, and the pressure plate can be rotated by a rotating shaft. This existing platform printer can facilitate position adjustment, and the pressure plate can be elastically retracted and retracted by the spring, and fixation is more convenient, but there are still some areas that can be optimized during use;

[0003] When existing flatbed printers are processing leather and other textile materials, wrinkles are likely to appear on the surface of leather and other textiles. The presence of wrinkles can easily have an adverse effect on the printing effect during printing, reducing the print quality. In addition, the raised wrinkles can easily collide with the nozzle and cause damage to the nozzle. At the same time, static electricity is likely to exist on the surface of leather and other textiles, further reducing the print quality. Therefore, it is necessary to make improvements.

[0077] The translation driving member 54 is located on a side of the upper pressing plate 52 and the lower pressing plate 53 away from the working platform 2 .

[0078] The translation drive member 54 further includes: a translation motor 540, which is disposed on the side wall of the first mounting frame 50; a connecting plate 541, which is disposed at the driving end of the translation motor 540;

[0079] The side of the upper pressing plate 52 away from the working platform 2 is movably connected to the connecting plate 541 , and the side of the lower pressing plate 53 away from the working platform 2 is connected to the connecting plate 541 .

When the charge on the surface of the material is negative, it will attract the positive charge in the airflow. When the charge on the surface of the material is positive, it will attract the negative charge in the airflow. During the operation of the ion fan 61, the external air enters the filter cartridge 7070 through the air inlet on the filter cartridge 7070. The several filter holes 710 on the filter cover 71 can perform preliminary filtration on the external air, and the filter element 72 can further filter the external air, thereby preventing dust and fibers floating in the air from polluting the ion fan 61, ensuring that the ion fan 61 can stably blow the positively and negatively charged airflow. Compared with the prior art, the present invention can ensure the stability of the static electricity removal effect.

[0087] Example 4:

[0088] The present embodiment provides a flatbed printer, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the dustproof member 7 further comprises: a second mounting bracket 73, which is detachably mounted on the top of the filter cartridge 70; a dredging plate 74, the lower surface of which is provided with a plurality of dredging needles 740; a first push rod 75, which is movably mounted on the second mounting bracket 73 and can be raised and lowered in the vertical direction, the bottom end of the first push rod 75 being connected to the upper surface of the dredging plate 74; a spring 76, which is sleeved on the first push rod 75, the bottom end of the spring 76 being connected to the upper surface of the second mounting bracket 73, and the upper end being connected to the top of the first push rod 75;

[0089] Among them, the plurality of clearing needles 740 correspond one to one with the plurality of filtering holes 710 .

[0090] In this embodiment, when the filter plate is clogged, the first push rod 75 is pushed downward, and the first push rod 75 drives the dredging plate 74 to approach the filter cover 71, so that the dredging needle 740 punctures the filter hole 710, dredges the impurities clogged in the filter hole 710, and then collects the impurities into the filter element 72 of the filter cartridge 7070. After the dredging is completed, the spring 76 drives the first push rod 75 to reset, so that the dredging plate 74 is away from the filter cover 71, which is convenient for the next dredging. Compared with the prior art, the present invention can facilitate the dredging of the filter cover 71, and it is not easy to generate dust and cause secondary pollution during the dredging process, which further ensures the stability of the electrostatic removal effect.

The socket can be vertically penetrated downward by the first push rod 75 to the lower surface of the dredging plate 74. The lower end of the second push rod 78 can pass through the socket and be connected to the upper surface of the grinding plate 77. The grinding plate 77 and the dredging plate 74 can be magnetically attached through a conventional magnetic connection.

[0095] In this embodiment, when long fibers appear on the filter cover 71 and the filter holes 710 are blocked, the second push rod 78 can be pushed to drive the grinding plate 77 closer to the filter cover 71. When the grinding plate 77 is pushed, it separates from the dredging plate 74. After approaching the surface of the filter cover 71, the second push rod 78 is rotated to drive the grinding plate 77 to rotate, and the grinding knife 770 on the grinding plate 77 is used to grind the fibers, so that the fibers can enter the filter cartridge 70 under the action of suction and finally be collected in the filter element 72. After dredging is completed, the second push rod 78 is lifted to drive the grinding plate 77 closer to the dredging plate 74, and the position of the grinding plate 77 is adjusted so that the dredging needle 740 passes through the perforation. Finally, the grinding plate 77 and the dredging plate 74 are attached together by magnetic attraction.

[0102] S2. During the feeding process, the control console 100 controls the static removal mechanism 6 to start, and the ion fan 61 can blow air with positive and negative charges onto the material to neutralize the charge on the material. When the charge on the surface of the material is negative, it will attract the positive charge in the air flow, and when the charge on the surface of the material is positive, it will attract the negative charge in the air flow;

[0103] S3. After the material is placed on the working platform 2, the material is stretched and flattened by the tensioning and flattening mechanism 5 to eliminate wrinkles on the material.
