[0001] This application relates to the field of fabric printing technology, and more particularly to a printer. Background Technology

[0002] Fabric printing refers to the process of applying dyes or pigments to create patterns on fabric. Fabric printing can be achieved through printing, and since fabrics are usually wide, wide-format printers are generally used. Wide-format printers can print on both wide and narrow fabrics.

[0003] However, wide-format printers can only print one roll at a time. When the width of the fabric is less than half of the printer's maximum printing width, the printer's printing efficiency will be severely reduced. Summary of the Invention

The three fixed seats are arranged at intervals along the extension direction of the connecting beam. The two ends of the second flattening rollers are respectively rotatably connected to two adjacent fixed seats.

[0014] In some embodiments, the two second flattening rollers are of equal length.

[0015] In some embodiments, the printer further includes a tensioning mechanism disposed at the front end of the tensioning mechanism, the tensioning mechanism being used to tension the printing medium between the printer and the unwinding mechanism.

[0016] In some embodiments, the printer further includes a cleaning mechanism disposed at the front end of the tensioning mechanism, the cleaning mechanism being used to clean lint or contaminants from the printing medium.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0048] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0049] To address the aforementioned technical problems, embodiments of this application provide a printer 100, such as... Figure 1 and Figure 2As shown, printer 100 includes a mounting frame 1, an unwinding mechanism 2, a tensioning mechanism 3, a flattening mechanism 4, a conveying mechanism 5, and a printing mechanism 6. The mounting frame 1 is used to mount the tensioning mechanism 3, the flattening mechanism 4, the conveying mechanism 5, and the printing mechanism 6, and can also be used to mount the unwinding mechanism 2; the unwinding mechanism 2 is used for unwinding; the tensioning mechanism 3 is used for tensioning the printing media; the flattening mechanism 4 is used for flattening the printing media; the conveying mechanism 5 is used for conveying and supporting the printing media; and the printing mechanism 6 is used for printing on the printing media. The full-width printing media refers to the printing media with the maximum width that printer 100 can print. Optionally, the printing media is a roll of cloth.

[0050] Next, the specific structures of the mounting frame 1, unwinding mechanism 2, tensioning mechanism 3, flattening mechanism 4, conveying mechanism 5, and printing mechanism 6 will be described in turn.

[0051] For the aforementioned mounting bracket 1, as Figure 2 As shown, the mounting bracket 1 includes two wall panels 101 and a mounting beam 102 connecting the two wall panels 101, and the two wall panels 101 are fixed to each other by the mounting beam 102. The two wall panels 101 are parallel to each other and extend through each other along the thickness direction of the wall panels 101, and the two wall panels 101 completely overlap.

[0052] For the unwinding mechanism 2 mentioned above, such as Figure 1 As shown, the unwinding mechanism 2 includes a first unwinding component 201 and a second unwinding component 202, both of which are used to unwind the printing medium. The first unwinding component 201 and the second unwinding component 202 can be used individually or simultaneously. When used individually, i.e., when the printer 100 performs single-roll printing, the first unwinding component 201 and the second unwinding component 202 can unwind full-width printing medium or non-full-width printing medium. When used simultaneously, i.e., when the printer 100 performs dual-roll printing, both the first unwinding component 201 and the second unwinding component 202 are used to unwind non-full-width printing medium, and the first unwinding component 201 and the second unwinding component 202 do not interfere with each other. Optionally, the first unwinding component 201 is set independently and can be placed directly on the ground for unwinding printing media with a large roll diameter or heavy weight, i.e., for unwinding printing media with a large roll diameter; the second unwinding component 202 is set on the mounting frame 1 for unwinding printing media with a small roll diameter or light weight, i.e., for unwinding printing media with a small roll diameter.

[0053] It should be noted that, in the embodiments of this application, for ease of description, the concepts of "front end" and "back end" are introduced. "Front end" and "back end" are relative to the direction of movement of the printing medium, and the printing medium moves from the "front end" to the "back end".

[0054] For the aforementioned tensioning mechanism 3, such as Figure 1 and Figure 3 As shown, the tensioning mechanism 3 is located at the rear end of the unwinding mechanism 2. The tensioning mechanism 3 includes a first tensioning component 301 and a second tensioning component 302, both of which are used to tension the printing media. It can be understood that when the printer 100 performs dual-roll printing, the first tensioning component 301 and the second tensioning component 302 are used to tension the two printing media separately, or one of the first tensioning component 301 and the second tensioning component 302 can tension the two printing media simultaneously. When the printer 100 performs single-roll printing, either the first tensioning component 301 or the second tensioning component 302 is used to tension the printing media. It should be noted that when the printer 100 performs dual-roll printing, if the two printing media are of the same material, they can be tensioned simultaneously by one of the first tensioning component 301 and the second tensioning component 302; if the two printing media are of different materials, they need to be tensioned separately by the first tensioning component 301 and the second tensioning component 302. By tensioning the two printing media respectively by the first tensioning component 301 and the second tensioning component 302, the tension can be adjusted according to the different material properties of the two printing media to make the tension of the two printing media more stable during transportation and improve the printing effect. At the same time, it can also make the tension of the two printing media equal or close to equal during transportation, so as to reduce the slippage deviation of the two printing media during transportation and improve the phenomenon of stretching of the pattern on the printing media caused by the asynchrony of the two printing media.

[0055] For the aforementioned tensioning components, such as Figure 3 As shown, the tensioning assembly includes two swing arms 3011, a tensioning roller 3012, and a driver 3013. The swing arms 3011 are rotatably connected to the wall plate 101. Both ends of the tensioning roller 3012 are rotatably connected to the two swing arms 3011 respectively. The driver 3013 is disposed on the wall plate 101 and is drively connected to the swing arms 3011. The driver 3013 drives the swing arms 3011 to rotate, thereby tensioning the printing media with the tensioning roller 3012. By driving the swing arms 3011 to rotate relative to the wall plate 101 via the driver 3013, the tensioning roller 3012 disposed on the swing arms 3011 moves relative to the wall plate 101, thereby tensioning or releasing the printing media, and the tension can be adjusted. It is understandable that the rotation axes of the two swing arms 3011 coincide and are perpendicular to the wall plate 101, the tension roller 3012 is also perpendicular to the wall plate 101, the rotation axis of the tension roller 3012 is spaced apart from the rotation axis of the swing arms 3011, and the driver 3013 is connected to the swing arms 3011 in a transmission connection to drive the swing arms 3011 to rotate.

[0056] In some embodiments, the driver 3013 is a cylinder (not shown), the cylinder body of which is rotatably mounted on the mounting bracket 1, the output shaft of which is rotatably connected to the swing arm 3011, and the rotation axis of the output shaft is spaced apart from the rotation axis of the swing arm 3011, so that when the output shaft moves in extension and retraction, it can drive the swing arm 3011 to rotate relative to the wall plate 101.

[0057] In other embodiments, the driver 3013 may also be a motor (not shown) that drives the swing arm 3011 to rotate via gears or a chain.

[0058] Furthermore, such as Figure 3 As shown, there are two tension rollers 3012. The middle part of the swing arm 3011 is rotatably connected to the wall plate 101, and the two ends of the swing arm 3011 are respectively rotatably connected to the two tension rollers 3012. That is, two tension rollers 3012 are provided on a set of swing arms 3011, and the two tension rollers 3012 are respectively located on both sides of the rotation axis of the swing arm 3011. Thus, the printing medium can be tensioned simultaneously by the two tension rollers 3012, thereby enhancing the tensioning effect.

[0059] For the aforementioned flattening mechanism 4, such as Figure 1 and Figure 2 As shown, the flattening mechanism 4 is located at the rear end of the tensioning mechanism 3. The flattening mechanism 4 is used to flatten one or two printing media. That is, the flattening mechanism 4 can flatten one printing media or two printing media simultaneously to reduce wrinkles on the surface of the printing media and improve print quality. Specifically, as shown... Figure 3 As shown, the flattening mechanism 4 includes a single-roll flattening component 401 and a dual-roll flattening component 402. When the printer 100 performs single-roll printing, the single-roll flattening component 401 is used to flatten the printing medium; when the printer 100 performs dual-roll printing, the dual-roll flattening component 402 is used to flatten the two printing media. That is, the flattening mechanism 4 can flatten one printing medium or two printing media simultaneously.

[0060] For the aforementioned single-roll flattening component 401, such as Figure 4 As shown, the single-roll flattening assembly 401 includes two first mounting seats 4011 and a first flattening roller 4012. The first mounting seats 4011 are mounted on the wall panel 101, and the two ends of the first flattening roller 4012 are rotatably connected to the two first mounting seats 4011 respectively. The single-roll flattening assembly 401 is provided with a single first flattening roller 4012, which is capable of flattening a single printing medium. The single-roll flattening assembly 401 can flatten a full-width printing medium. Optionally, the first flattening roller 4012 is perpendicular to the wall panel 101.

[0061] For the aforementioned double-roll flattening assembly 402, such as Figure 5As shown, the dual-roll flattening assembly 402 includes two second mounting seats 4021, a connecting beam 4022, three fixed seats 4023, and two second flattening rollers 4024. The second mounting seats 4021 are mounted on the wall panel 101. Both ends of the connecting beam 4022 are connected to the two second mounting seats 4021 respectively. The three fixed seats 4023 are spaced apart along the extension direction of the connecting beam 4022. Both ends of the second flattening rollers 4024 are rotatably connected to two adjacent fixed seats 4023 respectively. The dual-roll flattening assembly 402 has two second flattening rollers 4024, enabling simultaneous flattening of two non-full-width printing media. Optionally, the rotation axes of the two second flattening rollers 4024 coincide and are perpendicular to the wall panel 101. Optionally, the lengths of the two second flattening rollers 4024 are equal.

[0062] In an optional embodiment, the first flattening roller 4012 and the second flattening roller 4024 are opening rollers.

[0063] The printer 100 of this application embodiment, compared with the traditional wide-format printer 100, is provided with two sets of flattening components and two sets of tensioning components, so that it can achieve dual-roll printing in addition to single-roll printing.

[0064] For the aforementioned conveying mechanism 5, such as Figure 1 and Figure 2 As shown, the conveying mechanism 5 is located at the rear end of the flattening mechanism 4, and is used to convey the printing media. The surface of the conveying mechanism 5 used to convey the printing media is the conveying surface 501. When the printer 100 prints a single roll, the conveying mechanism 5 conveys a single printing medium, which can either cover the entire conveying surface 501 or only a portion of it. When the printer 100 prints two rolls simultaneously, the conveying mechanism 5 conveys two printing media simultaneously, which can either cover the entire conveying surface 501 or only a portion of it. The two printing media are spaced apart on the conveying surface 501 to prevent interference between them. Optionally, the width of the conveying surface 501 is equal to the width of the full-width printing medium.

[0065] It is understandable that when printer 100 performs single-roll printing, the conveyor mechanism 5 can convey full-width printing media; when printer 100 performs dual-roll printing, the sum of the widths of the two printing media needs to be less than or equal to the width of the full-width printing media so that the two printing media do not overlap.

[0066] In some embodiments, such as Figure 1 and Figure 6As shown, the conveying mechanism 5 includes a conveyor belt 502, which is used to convey the printing medium. Adhesive can be provided on the conveyor belt 502 so that the printing medium adheres to the conveyor belt 502. Thus, when the conveyor belt 502 moves, it can convey the printing medium to the printing position, that is, to the position between the printing mechanism 6 and the conveying mechanism 5.

[0067] Furthermore, such as Figure 1 and Figure 6 As shown, the conveying mechanism 5 also includes a cleaning component 503, which is used to clean the conveyor belt 502 to remove ink, debris, dust, or other contaminants from its surface. Specifically, the cleaning component 503 includes a cleaning tank 5031 and a plurality of cleaning rollers 5032. The cleaning tank 5031 can contain a cleaning solution, such as water. The cleaning rollers 5032 are rotatably disposed in the cleaning tank 5031, with one side of their outer peripheral surface in contact with the conveyor belt 502 and the other side located inside the cleaning tank 5031. The cleaning rollers 5032 can adhere to the cleaning solution in the cleaning tank 5031 to clean the conveyor belt 502. Furthermore, contaminants adhering to the cleaning rollers 5032 can detach from the cleaning rollers 5032 after entering the cleaning solution, thus improving the problem of contamination of the conveyor belt 502 by the cleaning rollers 5032. Optionally, the cleaning tank 5031 may also contain rollers that contact the cleaning rollers 5032 for removing contaminants from the outer peripheral surface of the cleaning rollers 5032.

[0068] Furthermore, such as Figure 1 and Figure 6 As shown, the conveying mechanism 5 also includes a scraper 504, which is disposed in the cleaning box 5031. The scraper 504 contacts the conveyor belt 502 and is used to scrape off contaminants from the surface of the conveyor belt 502.

[0069] Furthermore, such as Figure 1 and Figure 6 As shown, the conveying mechanism 5 also includes a drying assembly 505, which is used to dry the conveyor belt 502. Since the cleaning roller 5032 adheres cleaning fluid to the conveyor belt 502, it affects the adhesion between the printing medium and the conveyor belt 502, and the cleaning fluid also adheres to the printing medium, affecting the printing effect. In this embodiment, by drying the conveyor belt 502, the residue of cleaning fluid can be reduced, improving the aforementioned problems affecting the adhesion between the printing medium and the conveyor belt 502, and also improving the problem of cleaning fluid affecting the printing effect.

[0070] For the aforementioned printing mechanism 6, such as Figure 1 and Figure 6As shown, the printing mechanism 6 is positioned above the conveying mechanism 5 and is used to print the printing media located on the conveying mechanism 5. Specifically, it prints the printing media located on the conveying surface 501. When the printer 100 prints a single roll, the conveying mechanism 5 conveys a single printing medium, and the printing mechanism 6 can print the single printing medium on the conveying surface 501. This single printing medium can be a full-width printing medium. When the printer 100 performs dual-roll printing, the conveying mechanism 5 conveys two printing media simultaneously, and the printing mechanism 6 can print the two printing media on the conveying surface 501 simultaneously. Optionally, the printing mechanism 6 is an inkjet printing carriage.

[0071] In some embodiments, such as Figures 1 to 3 As shown, the printer 100 also includes a tensioning mechanism 7, which is located at the front end of the tensioning mechanism 3. The tensioning mechanism 7 is used to tension the printing medium between the printing medium and the unwinding mechanism 2. By setting the tensioning mechanism 7, the printing medium can be tightened, reducing the amount of contaminants adhering to the bottom surface of the printing medium. Specifically, the tensioning mechanism 7 includes a tensioning roller 701, which is rotatably mounted on the wall plate 101. When the tensioning roller 701 rotates, it can tighten the printing medium, thereby cooperating with the unwinding mechanism 2 to tighten the printing medium between them.

[0072] In some embodiments, such as Figures 1 to 3 As shown, the printer 100 also includes a cleaning mechanism 8, which is located at the front end of the tensioning mechanism 3. The cleaning mechanism 8 is used to clean lint or contaminants from the printing media. By including the cleaning mechanism 8, lint, impurities, dust, and other contaminants on the printing media can be removed, improving the printing quality. Specifically, as... Figure 4 As shown, the cleaning mechanism 8 includes a cleaning roller 801. A brush is provided on the outer peripheral surface of the cleaning roller 801. When the cleaning roller 801 rotates, it can remove lint or contaminants from the printing medium through the brush. A collection tray 802 can also be provided below the cleaning roller 801 to collect the lint or contaminants cleaned off by the cleaning roller 801.

[0073] In some embodiments, such as Figures 1 to 3 As shown, the printer 100 also includes a traction mechanism 9, which is located at the front end of the tensioning mechanism 3. The traction mechanism 9 is used to drive the printing media. Specifically, the traction mechanism 9 includes a traction roller 901. When the traction roller 901 rotates, it can apply a frictional force to the printing media to drive the printing media along the rotation direction of the traction roller 901, thereby driving the printing media. Optionally, the traction mechanism 9 can provide traction force in both forward and reverse directions.

[0074] In some embodiments, such as Figures 1 to 3As shown, the printer 100 also includes a rolling mechanism 10, which is positioned above the conveying mechanism 5. The rolling mechanism 10 works in conjunction with the conveying mechanism 5 to flatten the printing medium. By having the rolling mechanism 10 work with the conveying mechanism 5 to hold the printing medium, the printing medium can be laid flat on the conveying mechanism 5, facilitating printing by the printing mechanism 6 and improving print quality. Specifically, the rolling mechanism 10 includes a rolling roller 1001. A preset gap is left between the outer circumference of the rolling roller 1001 and the conveyor belt 502 of the conveying mechanism 5. This preset gap is less than or equal to the thickness of the printing medium. When the printing medium passes through this preset gap, it can be pressed firmly onto the conveyor belt 502 by the rolling roller 1001, so that the printing medium is laid flat on the conveyor belt 502. This improves the problem of the printing medium bulging or lifting on the conveyor belt 502, improves print quality, and also improves the problem of the printing medium touching the print head of the printing mechanism 6 during transport, which could cause print head damage. When adhesive is provided on the conveyor belt 502, the rolling mechanism 10 can smoothly paste the printing medium onto the conveyor belt 502.

[0075] In some embodiments, such as Figure 1 As shown, the printer 100 also includes a color-fixing mechanism 11, which is located at the rear end of the conveying mechanism 5. The color-fixing mechanism 11 is used to fix the ink on the printing medium. By fixing the ink on the printing medium, the problem of ink fading can be improved, thus enhancing product quality. Specifically, the color-fixing mechanism 11 includes an oven. When the printing medium passes through the oven, it can be heated, thereby curing the ink and fixing the ink on the printing medium.

[0076] In some embodiments, such as Figures 1 to 3 As shown, the printer 100 also includes a guide roller 12, which is rotatably mounted on the wall plate 101. The guide roller 12 is used to change the transport direction of the printing media. The guide roller 12 can be located at the front or rear end of the mechanism to make the angle at which the printing media enters or leaves the mechanism more reasonable, thereby reducing the resistance to the movement of the printing media.

[0077] In one specific embodiment, such as Figure 1 , Figure 3 and Figure 6 As shown, the unwinding mechanism 2, the tensioning mechanism 7, the cleaning mechanism 8, the traction mechanism 9, the tensioning mechanism 3, the flattening mechanism 4, the rolling mechanism 10, the conveying mechanism 5, the printing mechanism 6, and the color fixing mechanism 11 are arranged sequentially along the conveying direction of the printing medium.

[0078] In some embodiments, the printer 100 may differ from a conventional wide-format printer 100 only in the unwinding mechanism 2, tensioning mechanism 3, and flattening mechanism 4, while all other components may be the same.

[0079] In this embodiment of the application, the printer 100, when printing, causes the printing medium to pass sequentially through the unwinding mechanism 2, the tightening mechanism 7, the cleaning mechanism 8, the traction mechanism 9, the tensioning mechanism 3, the flattening mechanism 4, the rolling mechanism 10, the conveying mechanism 5, the printing mechanism 6, and the color fixing mechanism 11, and then prints. When the printer 100 prints a single roll, the printing medium is placed in the first unwinding assembly 201 or the second unwinding assembly 202 according to the size of the roll material. The printing medium passes through one of the first tensioning assembly 301 or the second tensioning assembly 302 and passes through the single roll flattening assembly 401. When the printer 100 prints two rolls, the two printing media are placed in the first unwinding assembly 201 and the second unwinding assembly 202 respectively, or both can be placed in the first unwinding assembly 201 or the second unwinding assembly 202. The two printing media pass through the first tensioning assembly 301 and the second tensioning assembly 302 respectively, and the two printing media pass through the two second flattening rollers 4024 of the double roll flattening assembly 402 respectively, or pass through the single roll flattening assembly 401 and the double roll flattening assembly 402 respectively.

[0080] The printer 100 of this embodiment can print full-width printing media when printing a single roll, and can print two non-full-width printing media when printing two rolls, thereby improving the printing efficiency of the printer 100. The printer 100 is also provided with a flattening mechanism 4, a tensioning mechanism 7, and a rolling mechanism 10, which can flatten, tension, and lay out the printing media, improving the printing quality. The printer 100 is also provided with a cleaning mechanism 8, and a cleaning component 503 is provided in the conveying mechanism 5, which can reduce contaminants on the printing media and improve printing quality. The conveying mechanism 5 is also provided with a drying component 505, which can reduce the impact of cleaning fluid on the printing media. The printer 100 is also provided with a color-fixing mechanism 11, which can improve the problem of color fading of the printing media.
