Description

Technical Field

[0001] The invention relates to the field of printing technology, and in particular to a powder shaking mechanism for printing. Background Art

[0002] Powder printing is a process of printing powder raw materials on the surface of printed packaging or printed paper using processes such as gluing, spraying powder, and drying to create a strong visual effect. However, the existing powder printing process cannot be completed through mechanical automation and is usually completed manually. During manual production, it needs to be carried out in a relatively closed environment to prevent powder from flying to other areas and affecting production. Afterwards, glue is applied manually, powder is sprinkled, and the powder on the paper is manually shaken off. During this process, small particles of powder are easily inhaled by workers, endangering their health. Secondly, the excess powder is not recycled after being shaken off, resulting in large material loss.

[0043] By adopting the above technical solution, during operation, the material bin 21 is filled with powder for printing. When the slide 35 is in use, the walking device 4 moves the slide to the left extreme position of the device, stops, and the slide automatically extends. At this time, the user then places the paper on the slide 35, and one end of the paper flips the pressing plate 33 through the rotating shaft. The torsion spring between the ear plate and the rotating shaft is elastically squeezed so that the pressing plate 33 fixes one end of the paper, so that the paper is stably laid flat on the slide 35. Then, the controller connected to the device controls the device to run, and synchronously controls the running and resetting of the walking device 4. , the bevel gear 1 44 inside the transmission box 42 is driven to rotate by the driving motor 25, at which time the bevel gear 2 45 meshed with the bevel gear 1 44 rotates, and then the bevel gear 2 45 drives the transmission shaft 43 to rotate, at which time the gears 46 fixed at both ends of the transmission shaft 43 rotate, and the chain 47 meshed with the gear 46 drives the sliding frame 31 to slide on the fixed frame 2 34 under the fixing action of the fixed block 48, until it stops when it reaches the right limit position switch of the device. During this process, the powder sprinkling device 2 fixed on the sliding frame 31 is always running to perform powder sprinkling on the lower paper surface;

[0044] The powder spreading device 2 is running, and the servo motor 41 drives the connecting shaft 24 in the material bin 21 to rotate, which drives the scraper 23 to rotate by a certain angle. The material on the scraper 23 falls through the gap between the scraper 23 and the material bin 21 after the rotation angle, and finally the powder falls through the leakage hole 22 at the bottom of the material bin 21 to the surface of the printed paper below, thereby achieving the purpose of powder spreading;

[0045] After the powdering is completed, the powdering stops, and the vibration motor 6 runs to vibrate the slide and the paper on the slide to shake the powder on the surface of the paper. Finally, the excess powder falls into the recovery box 5 below through the other end of the slide 35. When the powder shaking work is completed (control the running time of the vibration motor 6), the heating device 1 is started to run

[0046] The heating device 1 is running, and the internal heating lamp tube 15 conducts electricity to heat the air between the lampshade 13 in the outer shell 14. At the same time, the fan 12 is running, sucking the external wind through the air duct 11 into the lampshade 13, blowing the internal heated air, and the heated air is blown through the opening at the bottom of the outer shell 14 to the surface of the paper below after the powder is sprinkled, and then the powder is heated and fixed, and the powder is evenly applied. After the processing is completed, the transmission parts are driven in reverse to run, and each device is reset to wait for the powder printing processing of the next group of papers. The movement position of the sliding frame 31 is mainly sensed by the sensing table and fed back to the controller to control the operation status of the transmission parts. The built-in sensor on the sensing table senses the displacement of the sliding frame 31.

[0047] Specifically, Figure 1 and Figure 7 and Figure 6As shown, the powder spreading device 2 includes a material bin 21 fixed to the front end face of the shell 14, and the interior of the material bin 21 is rotatably connected to a connecting shaft 24, and the exterior of the connecting shaft 24 is symmetrically fixedly connected to a scraper 23. The material bin 21 is loaded with printing powder, and the printing powder is located on the upper side of the scraper 23. A driving motor 25 is fixed to one end of the exterior of the material bin 21, and the output shaft of the driving motor 25 is fixed to the connecting shaft 24.

[0048] Specifically, Figure 2 and Fig.10 As shown, a vibration motor 6 is fixed to the lower end surface of the slide 35, induction tables are fixed to the lower positions of both ends of the fixed frame 2 34, a recovery box 5 is arranged below the fixing device 3, and brackets 51 are fixed to both ends of the recovery box 5, and the brackets 51 are fixed to the external support device.

[0049] Working principle: During operation, the powder used for printing is added to the material bin 21. When the slide 35 is in use, the walking device 4 moves the slide to the left extreme position of the device, stops, and the slide automatically extends. At this time, the user then places the paper on the slide 35, and one end of the paper flips the pressure plate 33 through the rotating shaft. The torsion spring between the ear plate and the rotating shaft is elastically squeezed so that the pressure plate 33 fixes one end of the paper, so that the paper is stably laid flat on the slide 35. Then, the controller connected to the device controls the device to run, and synchronously controls the running and resetting of the walking device 4. The driving motor 25 drives the bevel gear 1 44 inside the transmission box 42 to rotate, and the bevel gear 2 45 meshed with the bevel gear 1 44 rotates, and then the bevel gear 2 45 drives the transmission shaft 43 to rotate, and the gears 46 fixed at both ends of the transmission shaft 43 rotate, and the chain 47 meshed with the gear 46 drives the sliding frame 31 to slide on the fixed frame 2 34 under the fixing action of the fixed block 48, until it stops when it reaches the right limit position switch of the device. During this process, the powder sprinkling device 2 fixed on the sliding frame 31 is always running to sprinkle powder on the paper surface on the lower side;

[0050] The powder spreading device 2 is running, and the servo motor 41 drives the connecting shaft 24 in the material bin 21 to rotate, which drives the scraper 23 to rotate by a certain angle. The material on the scraper 23 falls through the gap between the scraper 23 and the material bin 21 after the rotation angle, and finally the powder falls through the leakage hole 22 at the bottom of the material bin 21 to the surface of the printed paper below, thereby achieving the purpose of powder spreading;

[0051] After the powdering is completed, the powdering stops, and the vibration motor 6 runs to vibrate the slide and the paper on the slide to shake the powder on the surface of the paper. Finally, the excess powder falls into the recovery box 5 below through the other end of the slide 35. When the powder shaking work is completed (control the running time of the vibration motor 6), the heating device 1 is started to run

[0052] The heating device 1 is running, and the internal heating lamp tube 15 conducts electricity to heat the air between the lampshade 13 in the outer shell 14. At the same time, the fan 12 is running, sucking the external wind through the air duct 11 into the lampshade 13, blowing the internal heated air, and the heated air is blown through the opening at the bottom of the outer shell 14 to the surface of the paper below after the powder is sprinkled, and then the powder is heated and fixed, and the powder is evenly applied. After the processing is completed, the transmission parts are driven in reverse to run, and each device is reset to wait for the powder printing processing of the next group of papers. The movement position of the sliding frame 31 is mainly sensed by the sensing table and fed back to the controller to control the operation status of the transmission parts. The built-in sensor on the sensing table senses the displacement of the sliding frame 31.
