DETAILED DESCRIPTION

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0038] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0039] Example 1: The specific structure of this utility model is as follows:

[0040] Please refer to the appendix. Figures 1-5 This utility model discloses a printing device, including a frame 9 and a feeding unit 1 disposed in the feeding direction of the frame 9. The feeding unit 1 includes a loading box 11, and the loading box 11 has two opposing vertical guide rails 12 on its opposite inner sides. Figure 1 As shown, the frame 9 is assembled from multiple profiles to form a frame body. At least one guide roller 14 is provided at the lower part of the frame body at the feeding end of the frame 9. The frame 9 also has an upward feeding channel, on which a ladder-type guide roller assembly 4 is obliquely mounted. Two platforms 8 are provided along the length direction of both sides of the upper end of the frame 9. Linear guide rails 3 are provided along the length direction of both platforms 8. The area between the two platforms 8 is the printing working area. A printing carriage 6 slides along the two linear guide rails 3 and moves above the printing working area. A first motor 10 is installed on one side of the frame 9. The first motor 10 is driven and connected to the printing carriage 6 through a pulley assembly. The first motor 10 drives the pulley assembly to run. One node of the upper belt of the pulley assembly is fixedly connected to the printing carriage 6. Through the rotation of the pulley assembly, the printing carriage 6 moves along the printing working area.

[0041] The printing carriage 6 includes:

[0042] A mounting base plate 62 is slidably connected to the two linear guide rails 3. The upper surface of the mounting base plate 62 is provided with double rows of guide rails 61 perpendicular to the linear guide rails 3.

[0043] The printer host 63 is slidably connected to the double-row guide rails 61. The printer body 63 is used for printing.

[0044] An ink supply system 65 is provided on the mounting base plate 62, and the ink supply system 65 supplies ink to the printer host 63. The ink supply system 65 is an inkjet ink supply system.

[0045] The printing device further comprises a print head cleaning mechanism 2, a cooling area 5, a CCD visual positioning area 101, and a pulling power mechanism 7.

[0046] The print head cleaning mechanism 2 is installed on the frame 9 and is arranged at the first end of the printing work area. The print head cleaning mechanism 2 is used to clean the print head of the printing trolley 6. After the printing trolley 6 completes a printing task, the print head on the printing trolley 6 needs to be cleaned to prevent the print head from being blocked.

[0047] The cooling area 5 is arranged on the frame 9, and the cooling area 5 and the print head cleaning mechanism 2 are connected by the feeding channel. The cooling area 5 is cooled by water. During the printing process, the print head needs to be kept wet. If the temperature of the printing work area is too high, the ink on the print head will evaporate quickly, which will cause the print head to be blocked. Therefore, the cooling area 5 is arranged in the printing work area.

[0048] The CCD visual positioning area 101 is arranged on the frame 9. An upper layer of the CCD visual positioning area 101 is a glass plate, and a CCD visual light supplement lamp is arranged below the glass plate. The CCD camera detection system on the CCD visual positioning area 101 is used to detect whether the printed product is qualified. The qualified product is successfully rolled up and collected. The unqualified product is cut by manual operation. The outer end of the remaining material is pulled to the pulling power mechanism 7 for fixation.

[0049] The pulling power mechanism 7 is installed on the frame 9 and is arranged at the second end of the printing work area. The outer end of the paper tape or cloth tape needs to be pulled to the pulling power mechanism 7 for fixation. The pulling power mechanism 7 pulls the paper material or cloth material to make the paper material or cloth material enter the printing work area.

[0050] In the pulling direction, the feeding mechanism 1 further comprises a first inner roller 16, a dust removal roller 17, a pressing roller assembly 18, a dust removal roller assembly 19, a second inner roller 110, and a lifting roller assembly 13 which is slidably arranged on the two vertical guide rails 12. The lifting roller assembly 13 is drivingly connected with a lifting power mechanism which is installed in the feeding mechanism box 11. The power source of the lifting power mechanism is a second motor. The motor drives the lifting roller assembly 13 to perform lifting action, thereby tensioning the paper tape or cloth tape.

[0051] The dust removal roller 17 is arranged above the first inner roller 16 and is provided with a replaceable sticky layer. When the paper tape or cloth tape passes through the dust removal roller 17, the dust is removed by the sticky ability of the surface of the dust removal roller 17, thereby improving the cleanliness of the paper tape or cloth tape. The dust removal roller 17 is the first dust removal structure.

[0052] The pressure roller assembly 18 includes a material-pulling pressure roller and a material-pulling roller mounted on a first roller frame with similar rolling surfaces, the material-pulling pressure roller and the material-pulling roller being arranged vertically. The dust removal roller assembly 19 includes a dust removal bottom roller and a lifting dust-adhesive roller mounted on a second roller frame with similar rolling surfaces, wherein the second roller frame has a structure for lifting the lifting dust-adhesive roller. The structure for lifting the lifting dust-adhesive roller consists of opposing lifting channels on opposite sides of the second roller frame. The surface of the lifting dust-adhesive roller is also provided with a replaceable dust-adhesive layer. The dust-adhesive layer is replaceable. Here, the lifting dust-adhesive roller is a second dust removal structure. Therefore, through the two dust removal structures, the paper tape or cloth tape entering the printing work area can better adhere to the ink, improving print quality.

[0053] The second inner roller 110 is located directly above the two vertical guide rails 12. The lifting roller assembly 13 includes an I-shaped roller frame and two lifting rollers installed at the open ends on both sides of the I-shaped roller frame.

[0054] The ladder-type guide roller group 4 includes an inclined ladder roller frame 15, aluminum rollers installed at the upper and lower ends of the ladder roller frame 15, and a suction plate installed on the ladder roller frame 15 and located between the two aluminum rollers. The suction plate has a mesh, and the back side of the suction plate is connected to a negative pressure device through an air passage. The mesh is connected to the air passage.

[0055] In summary, this invention improves the feeding unit by incorporating two dust removal roller structures within it, simplifying the dust removal structure and enhancing the dust removal effect. Furthermore, this invention includes a height-adjustable lifting roller assembly within the feeding unit. By adjusting the height of the two lifting rollers in this assembly, the tension of the printing media can be continuously adjusted to meet printing requirements and improve print quality.

[0056] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
