Description

Technical Field

[0001] This utility model relates to the field of canvas inkjet printing technology, specifically to a canvas printing inkjet printing device. Background Technology

[0002] Canvas printing is a technique that uses inkjet printing equipment to print images directly onto canvas material. It combines digital printing with traditional art media and is commonly used in fields such as artistic creation, commercial displays, and interior decoration.

[0003] Chinese patent document CN215153193U discloses a canvas printing inkjet printing device. During inkjet printing, a pressing roller is set on the fixed plate to press the canvas tightly, preventing the canvas from wrinkling and creasing during the inkjet printing process, which would cause printing deviations. Compared with traditional inkjet printing devices, this device improves practicality.

[0004] However, in the above solution, the printing head needs to be adjusted by a lead screw to perform the printing work. Since both the pressing roller and the printing head are mounted on a fixed plate, the pressing roller and the printing head move synchronously, which requires the pressing roller to be adjusted frequently. This affects the stability of the canvas placement and makes the canvas prone to displacement during the printing process, resulting in a decrease in printing quality. Utility Model Content

[0031] Example 1

[0032] like Figure 1-4 As shown, the canvas printing inkjet device proposed in this utility model includes a mounting frame 1, a motor 3, a roller 13, a support assembly, and a clamping assembly.

[0033] The number of rollers 13 is at least two, and the two rollers 13 are rotatably mounted on the top of the mounting frame 1. The outer side of the rollers 13 is provided with a conveyor belt 2 for supporting them in use.

[0034] The motor 3 is mounted on the side of the mounting frame 1 and is connected to the roller shaft 13 for transmission.

[0035] The support assembly is installed at the top of one end of the mounting frame 1. At the end of the support assembly and above the roller shaft 13, there is a pressure roller 12 for rolling the canvas in use. This roller is used to lay the canvas flat on the conveyor belt 2 and press and fix the end of the canvas, so that the canvas is fixed flat in the printing area, avoiding displacement and ensuring printing accuracy and image quality.

[0036] The clamping assembly is installed at the top of the conveyor belt 2 and at the other end of the mounting frame 1 to clamp and fix the end of the canvas.

[0037] In an optional embodiment, a support plate 15 is provided at the top center of the mounting frame 1 and at the upper inner surface of the conveyor belt 2, which is used to keep the top of the conveyor belt 2 horizontal during use and prevent the conveyor belt 2 from sinking downwards during use.

[0038] In this embodiment, a motor 3 drives one roller 13 to rotate, and a conveyor belt 2 wraps around two rollers 13. The roller 13 drives the conveyor belt 2 while simultaneously rotating the other roller 13. The conveyor belt 2 transports the clamping assembly to the side of the pressure roller 12. Simultaneously, the clamping assembly moves the pressure roller 12 upwards, creating a gap between the pressure roller 12 and the conveyor belt 2. This moves the canvas end downwards into the clamping assembly, fixing the canvas end in place. Meanwhile, the motor 3 slowly reverses the roller 13, causing it to return to its original position via the conveyor belt 2. Simultaneously, the pressure roller 12 presses down on the canvas while the support assembly rotates, ensuring the canvas lies flat against the surface of the conveyor belt 2. This results in a smooth, wrinkle-free printing process, improving printing efficiency and quality.

[0039] Example 2

[0040] like Figure 4 As shown, the canvas printing inkjet device proposed in this utility model differs from the first embodiment in that the clamping assembly includes a housing 5, a hand-tightening bolt 6, and a pressure plate 7.

[0041] The housing 5 is installed at the top of the conveyor belt 2;

[0042] The pressure plate 7 is located inside the housing 5;

[0043] The hand-tightening bolt 6 is located at the top of the housing 5 and extends into the housing 5 to connect with the pressure plate 7.

[0044] In an optional embodiment, the end projection shape of the housing 5 is C-shaped, and the top of the conveyor belt 2 is provided with a boss 14. The upper end face of the boss 14 is flush with the inner bottom of the housing 5, so as to make the canvas lay flat on the conveyor belt 2 and avoid the end of the canvas from tilting or wrinkling.

[0045] In an optional embodiment, adjustment plates 4 are provided at both ends of the housing 5 and on both sides of the boss 14. The projected shape of the adjustment plates 4 is triangular. When in use, the pressure roller 12 is moved upward by the inclined side of the adjustment plates 4, so that there is a canvas placement gap between the pressure roller 12 and the conveyor belt 2, thereby allowing the canvas to move downward in the housing 5 from the pressure roller 12.

[0046] In an optional embodiment, the top of the housing 5 is provided with a threaded hole, and a hand-tightening bolt 6 is inserted into the threaded hole of the housing 5 and connected to the pressure plate 7. During use, the hand-tightening bolt 6 is moved toward the pressure plate 7 through the threaded hole, so that the hand-tightening bolt 6 exerts pressure on the pressure plate 7, thereby fixing the end of the canvas in the housing 5.

[0047] In this embodiment, the housing 5 is moved toward the pressure roller 12 by the conveyor belt 2, and the housing 5 drives the adjusting plate 4 to adjust the height of the pressure roller 12, so that the canvas is placed in the housing 5 below the pressure roller 12. At the same time, the pressure plate 7 is placed inside the housing 5 and presses the canvas. Meanwhile, the hand-tightened bolt 6 is squeezed through the threaded hole of the housing 5 to press the pressure plate 7, thereby making the pressure plate 7 firmly fix the end of the canvas. When the conveyor belt 2 drives the housing 5 to reset, the canvas moves and lies flat on the conveyor belt 2.

[0048] Example 3

[0049] like Figure 3 As shown, the canvas printing inkjet device proposed in this utility model differs from Embodiment 1 in that the support component includes a sleeve 9, a connecting rod 10, and a sleeve 11.

[0050] The sleeve 11 is fitted onto the end of the pressure roller 12 and connected to the bearing of the pressure roller 12;

[0051] Sleeve 9 is installed at the top of mounting bracket 1;

[0052] The connecting rod 10 is installed on the side of the sleeve 11 and one end is inserted into the sleeve 9 and rotatably connected to the sleeve 9.

[0053] In an optional embodiment, a torsion spring 8 is provided at one end of the connecting rod 10 and on the side of the sleeve 9, which is connected to the sleeve 9 and the middle of the connecting rod 10, so as to apply force to the connecting rod 10 during use, thereby increasing the pressure of the pressure roller 12 on the canvas.

[0054] In this embodiment, the sleeve 9 is connected to the mounting frame 1, and the two ends of the connecting rod 10 are connected to the sleeve 9 and the sleeve 11 respectively, so that the position of the pressure roller 12 is limited, and the pressure roller 12 rotates with the conveyor belt 2 in the sleeve 11, so that the conveyor belt 2 presses and flattens the canvas.

[0055] In this invention, the motor 3 drives the roller shaft 13 to rotate, which in turn drives the conveyor belt 2 to move. The conveyor belt 2 moves the housing 5 toward the pressure roller 12, causing the housing 5 to bring the adjusting plate 4 into contact with the pressure roller 12. The inclined edge of the adjusting plate 4 adjusts the height of the pressure roller 12, and the pressure roller 12 moves the end of the sleeve 11 upward. At the same time, the connecting rod 10 rotates in the sleeve 9 to limit the position of the pressure roller 12. The canvas is placed below the pressure roller 12 into the housing 5, and the pressure plate 7 is placed inside the housing 5, above the end of the canvas. The hand-tightened screw... Bolt 6 moves towards pressure plate 7 through the threaded hole of housing 5 and squeezes it, thereby making pressure plate 7 firmly fix the end of the canvas in housing 5. At the same time, motor 3 drives roller 13 to slowly reverse, so that roller 13 drives housing 5 to reset through conveyor belt 2, and pressure roller 12 moves down along the inclined edge of adjustment plate 4 to press the canvas. When housing 5 moves the canvas, the canvas drives pressure roller 12 to rotate on sleeve 11, so that pressure roller 12 flattens the canvas against the surface of conveyor belt 2, so that the canvas is laid flat in the printing area, ensuring no wrinkles during printing and improving printing efficiency and quality.

[0056] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
