Description

Technical Field

[0001] The present application relates to the field of thermal transfer printing technology, and more particularly to the field of compact wide-format roll printer technology. Background Art

[0002] One of the main challenges facing traditional wide-format thermal transfer printing equipment is the large space required. First, transfer film typically comes in roll form. Especially when the film is wide, this requires not only ample storage space but also sufficient space to support the roll during use. Second, the equipment's internal structure is complex, including multiple components such as the film transport drive system, ink station, and control panel. These components are often bulky, further increasing the overall space required.

[0003] In addition, in order to facilitate operation and maintenance, the equipment also needs to reserve a certain amount of operating space to facilitate daily maintenance work such as replacing the transfer film and cleaning the print head.

[0004] For this purpose, there are also wide-format roll printers suitable for small studios or production sites that need to save space, which can effectively meet the needs of personalized customization and small-batch production. Utility Model Content

[0005] In response to the above-mentioned needs, this application proposes a compact wide-format roll printer, which reduces unnecessary space occupation by optimizing the internal structure layout and the roll film unwinding device, while ensuring printing quality and operational convenience.

[0006] To achieve the above objectives, this application adopts the following technical solutions:

[0007] A compact wide-format roll printer comprises a printer body, a cooling device is provided at the bottom of the body, and an external ink cartridge is provided at the rear end of the body;

[0008] A support frame, supporting the machine body at the bottom of the machine body;

[0009] The rear end of the support frame is provided with an unwinding device for supporting the rolled film and unwinding it.

[0010] This application utilizes the space-consuming ink cartridges as external devices, utilizing the space at the bottom of the machine body to house a support frame and an unwinding device. This eliminates the need for additional workspace, allowing film rolls to be placed and unwound at the bottom of the machine, saving space and improving unwinding synchronization to ensure print quality. It also enhances the cooling effect of the cooling device located at the bottom.

[0011] In some possible embodiments, the machine body includes a printing platform, with a film transport drive device and an ink station disposed on either side of the printing platform. This separates the film transport drive device and the ink station, which occupy a larger space, allowing the printing platform to be centered, thereby improving overall film unwinding and transport stability.

[0012] Furthermore, ventilation holes are provided on the left and right sides respectively, which can provide an efficient cooling solution.

[0013] Furthermore, inspection doors are provided on the left and right sides respectively, and the ventilation holes are provided on the inspection doors, so that the main components can be inspected and repaired without disassembling the entire machine.

[0014] In some possible embodiments, the unwinding device includes a main guide roller for placing the roll film and an auxiliary guide roller arranged on the outer side of the upper end of the main guide roller. Through the design of the auxiliary guide roller, the roll film is guided to unfold and be transported to the printing platform, and the roll film at the bottom of the machine body can be smoothly transported to the printing platform.

[0015] In some possible implementations, the main roller is a height-adjustable structure with the support frame as a guide column.

[0016] Furthermore, the auxiliary guide rollers are spaced apart and positioned facing each other on the left and right sides. This balances the tension of the transfer film, ensuring it does not shift during transport. Furthermore, the gap in between avoids unnecessary pressure points on the transfer film, reducing friction and wear during transport, thereby improving print quality and extending the life of the transfer film.

[0017] Furthermore, the auxiliary guide roller is provided with a support plate and a positioning rod for guiding the support plate. The support plate can be displaced on the positioning rod to facilitate adjustment of the distance between the auxiliary guide rollers at both ends, so that the printer can adapt to rolls of film of different sizes.

[0024] The following examples further illustrate the features of the present application and other related features to facilitate understanding by those skilled in the art:

[0025] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "bottom" and "top", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0026] Please refer to Figure 1 and Figure 2 、 Figure 5 The present application discloses a compact wide-format roll printer, comprising a printer body 100, which is provided with a printing platform 110. The width of the printing platform 110 is the maximum width of the roll film that can be printed in a thermal transfer printer. Therefore, the overall printer width is limited by the width of the printing platform 110. Therefore, in this case, the ink cartridge 120, which occupies a relatively large space, is designed to be external and disposed at the rear end of the body 100. At the same time, a cooling device 130 is provided at the bottom of the body 100 to dissipate heat from the printing platform 110.

[0027] Please refer to Figure 5 The support frame 200 is set at the lower end of the entire body 100 and supports the body 100 at its bottom. It actually supports the body 100 and the cooling device 130, which is collectively referred to as the support for the body 100 below.

[0028] Please refer to Figure 2 In specific applications, the support frame 200 can be provided with a base 210 and support legs 220 between the base 210 and the body 100. The base 210 is provided with movable casters 211 and adjustable feet 212 for fixing, taking into account both displacement and positioning, and is suitable for applications in limited spaces.

[0029] At the rear end of the support frame 200, an unwinding device 300 is provided for supporting and unwinding the film roll. By utilizing the bottom space of the machine body 100 to house the support frame 200 and unwinding device 300, the film roll can be placed and unwound at the bottom of the machine without requiring additional workspace, saving space and improving unwinding synchronization to ensure printing quality.

[0030] At the same time, as described above, the bottom of the body 100 is actually the cooling device 130. When the bottom of the body 100 is in an open state with the support legs 220, the cooling effect of the cooling device 130 can be further improved.

[0031] Please refer to Figure 2 One possible implementation of the unwinding device 300 includes a main guide roller 310 for placing the film roll and an auxiliary guide roller 320 positioned outside the upper end of the main guide roller 310. Specifically, the main guide roller 310 uses the support legs 220 of the support frame 200 as guide posts and is height-adjustable. The main guide roller 310 comprises two support rollers 311 and a positioning device 312, a conventional technique for placing film rolls and will not be described in detail.

[0032] In this way, through the adjustable height design of the main roller 310 and the design of the auxiliary guide roller 320 arranged at its upper end facing outward, the roll film can be guided to be unwound by the main roller 310, and then conveyed from the outside to the inside to the printing platform after the auxiliary guide roller 320 unfolds outward. The roll film can be smoothly conveyed to the printing platform 110 using only the limited space at the bottom of the body 100.

[0033] Specifically, the auxiliary guide rollers 320 are spaced apart and facing each other on the left and right sides, with a gap between them. Firstly, the auxiliary guide rollers 320 balance the tension of the transfer film, ensuring that it does not shift during transport. Furthermore, the gap in between avoids unnecessary pressure points on the transfer film, reducing friction and wear during transport, thereby improving print quality and extending the life of the transfer film.

[0034] As a feasible embodiment of the auxiliary guide roller 320, please refer to Figure 4 The auxiliary guide roller 320 is provided with a support plate 321 and a positioning rod 322 guiding the support plate 321. The distance between the left and right auxiliary guide rollers 320 can be adjusted by moving the support plate 321 on the positioning rod 322, so that the entire printer can adapt to rolls of film of different sizes and widths.

[0035] In addition to the compact design of the mold opening device 300, the internal structure of the body 100 is also optimized accordingly. Figure 3 and Figure 5 On the left and right sides of the printing platform 100 as described above, a film transport drive device 140 and an ink station 150 are respectively provided. In actual operation, these two components are relatively large internal devices, which can improve the stability of the overall unwinding and film transport by centering the printing platform.

[0036] In practical applications, a printing device, not shown in this embodiment, commutes between the printing platform 100 and the ink station 150. The printing device also includes a printing device driver 141, which can be located on the same left side as the film transport driver 140. The control device for the ink station 150 can be located in the space above the ink station 150. This creates a compact arrangement of the ink station 150, ink cartridges 120, and their control device on the right side of the entire machine body 100, facilitating easy wiring and maintenance.

[0037] For further information, please refer to Figure 1 Ventilation holes 160 are provided on both sides to provide an efficient cooling measure. More preferably, inspection doors 170 are provided on both sides, which can be simple hinged opening and closing structures. The ventilation holes 160 are provided on the inspection doors 170, so that the main components can be inspected without disassembling the entire machine, and effective heat dissipation can be achieved in a compact structure.

[0038] As mentioned above, this case protects a compact wide-format roll printer, and all technical solutions that are identical or similar to those in this case should be deemed to fall within the scope of protection of this case.
