The smoothing roller is made of a soft and elastic material, which can adaptively adjust the pressure according to different inkjet printing materials, effectively smoothing out wrinkles and unevenness on the material surface.

Description

Technical Field

[0001] This application relates to the field of inkjet printer technology, and in particular to a digital inkjet printer. Background Technology

[0002] With the continuous development of digital inkjet printing technology, digital inkjet printers have been widely used in advertising, decoration, and industrial fields. In existing digital inkjet printer technology, the material positioning structure is a key factor in ensuring printing quality and efficiency. Currently, the material positioning structures of most digital inkjet printers on the market adopt mechanical clamping or adsorption methods, which can meet basic positioning requirements to a certain extent. However, for inkjet materials of different materials and thicknesses, mechanical clamping methods struggle to ensure the flatness of the material surface and positioning accuracy, resulting in poor printing effects. While adsorption methods can achieve relatively stable positioning, the adsorption force is affected in high humidity or high temperature environments, thus reducing the reliability of positioning. This offset phenomenon is particularly noticeable in large-area printing operations, causing inconvenience and losses for users.

[0003] Existing technical solutions are cumbersome to operate when changing materials and adjusting positioning, which reduces work efficiency.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue that mechanical clamping methods struggle to ensure material surface flatness and positioning accuracy, resulting in poor printing quality, and while adsorption methods can achieve relatively stable positioning, the adsorption force is affected in high humidity or high temperature environments, thus reducing positioning reliability, this application provides a digital inkjet printer.

[0006] The digital inkjet printer provided in this application adopts the following technical solution:

[0007] A digital inkjet printer includes an inkjet printer, wherein connecting rods are symmetrically fixed to one side of the outer wall of the inkjet printer, a rotating drum is rotatably provided between the two connecting rods, a feeding drum is installed on one side of the rotating drum, support rods are symmetrically provided on the top of the inkjet printer, a mounting frame is fixed on the support rods, a movable plate is symmetrically provided inside the mounting frame, an electric push rod is installed on the movable plate, and a smoothing roller is connected to the bottom end of the movable plate.

[0008] Preferably, the inkjet printer has adjustment cavities on both sides, and a linear motor is installed inside the adjustment cavity. The connecting rod is connected to the inkjet printer by bolts.

[0009] Preferably, a motor is installed on one side of the outer wall of the connecting rod, and the output end of the motor extends into the connecting rod and is connected to the feeding drum in a transmission manner.

A double-headed motor is installed in the middle of the inner wall of the sliding groove, and the output ends of the double-headed motor are connected to the lead screws for transmission.

[0011] Preferably, the lead screw is slidably provided with a matching slider, and the bottom end of the slider is connected to a connecting frame by screws, and the movable plate is rotatably connected to the connecting frame.

[0012] Preferably, both ends of the electric push rod are rotatably connected to connectors, one of which is fixed to the inner wall of the movable plate, and the other is fixed to the side wall of the slider. The bottom end of the movable plate is fixed with an installation head.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This application utilizes a smoothing roller on a digital inkjet printer to position materials. Driven downwards by an electric push rod, the smoothing roller rolls over the material surface and stops at the edge, serving a positioning function. When in contact with the material surface, it smooths out wrinkles to both sides. Made of a soft and elastic material, the smoothing roller can adaptively adjust pressure according to different inkjet printing materials, effectively smoothing wrinkles and unevenness on the material surface. Through simple operation and adjustment, smoothing and positioning of the inkjet printing material can be achieved, reducing operational difficulty and labor costs. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a digital inkjet printer. (Refer to...) Figures 1-2 The system includes a printer 1, with adjustment chambers 2 on both sides of the printer 1. A linear motor 3 is installed inside the adjustment chamber 2, and a printing head can be installed on the moving end of the linear motor 3 for printing the material inside the printer 1. A connecting rod 5 is symmetrically fixed to the outer wall of one side of the printer 1. The connecting rod 5 is connected to the printer 1 by bolts. A rotating drum 6 is rotatably provided between the two connecting rods 5. A feeding drum 7 is installed on one side of the rotating drum 6. A motor is installed on the outer wall of one side of the connecting rod 5. The output end of the motor extends into the connecting rod 5 and is connected to the feeding drum 7 for transmission. The rotation of the feeding drum 7 can drive the printed material to be fed outward, which plays an auxiliary role in feeding. The rotating drum 6 provides support.

[0022] like Figures 3-4 As shown, support rods 4 are symmetrically arranged on the top of the inkjet printer 1. Mounting brackets 8 are fixed on the support rods 4. The mounting brackets 8 have a sliding groove 12 inside. Screws 14 are rotatably installed on both sides of the inner wall of the sliding groove 12. A double-headed motor 13 is installed in the middle of the inner wall of the sliding groove 12. The output ends of the double-headed motor 13 on both sides are connected to the screws 14 for transmission. Matching sliders 16 are slidably arranged on the outside of the screws 14. The two sliders 16 can be driven to move closer or further apart by rotating the two screws 14. The bottom end of the sliders 16 is connected to the connecting bracket 9 by screws.

[0023] Furthermore, a movable plate 10 is rotatably installed inside the connecting frame 9, which can then drive the movable plate 10 to move on the inkjet printer 1. An installation head 15 is fixed at the bottom of the movable plate 10, and a smoothing roller 11 is rotatably installed inside the installation head 15. An electric push rod 17 is installed on the movable plate 10, and both ends of the electric push rod 17 are rotatably connected to a connector 18.

[0024] One of the connectors 18 is fixed to the inner wall of the movable plate 10, and the other connector 18 is fixed to the side wall of the slider 16. The movable plate 10 can be pushed outward or reset to a horizontal state by the telescopic operation of the electric push rod 17, which facilitates the smoothing roller 11 to smooth and position the material surface.

[0025] The implementation principle of a digital inkjet printer according to an embodiment of this application is as follows: In use, the material to be printed is laid on the inkjet printer 1 beforehand, with one end extending between the rotating drum 6 and the feeding drum 7 inside the connecting rod 5. Then, the electric push rod 17 is started, and the electric push rod 17 pushes the movable plate 10 to move downward. As the two movable plates 10 move to a vertical state, they will drive the smoothing roller 11 inside the mounting head 15 to contact the material surface. At this time, the smoothing roller 11 rolls to smooth the wrinkles on the material surface. At the same time, the screw 14 driven by the double-head motor 13 rotates, which drives the movable plate 10 to move away from both sides through the two sliders 16. The two smoothing rollers 11 will roll along the surface of the material to the edge, which can smooth the wrinkles to both sides and play a good positioning role. Then, the linear motor 3 can drive the pre-installed inkjet head to print on the material. Through simple operation and adjustment, the smoothing and positioning of the inkjet material can be achieved, reducing the difficulty of operation and labor costs.
