Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to a printing mechanism. Background Art

[0002] The printhead is the component in a printer that transfers text or images onto paper. Depending on the type of printer, the printhead typically consists of either print nozzles or a laser beam. In an inkjet printer, the printhead contains tiny nozzles that eject ink to create the image or text. In a laser printer, the printhead consists of a laser beam and scanning mirrors that control the movement and opening and closing of the beam to create the image or text. The quality and performance of the printhead directly impact the quality of prints, making it a crucial component in any printer.

[0003] See also Figure 1 , Figure 1 The print head is horizontally arranged inside the printing device. When the printing device prints normally, due to the bending of the tube head, when the tube head is printed downward, it is easy to cause scratches between the tube head and the inner wall and side wall of the shell, causing the tube head to curl and bend, thereby causing blockage at the front end of the tube, affecting the printing efficiency of the printing device. Utility Model Content

[0004] The purpose of the present utility model is to overcome the above-mentioned technical deficiencies and provide a printing mechanism to solve the technical problem that the print head in the prior art is set horizontally, which causes the tube head to bend downward when the catheter moves inside the device, making it easy for the tube head to rub against the inner wall and side wall of the shell, thereby causing blockage of the tube.

[0005] In order to achieve the above technical purpose, the present invention adopts the following technical solutions:

[0006] In a first aspect, the utility model provides a printing mechanism, comprising

[0007] plate body;

[0008] a swing end, the swing end being rotatably connected to the base plate and being positionable at a first position or a second position;

[0009] A printing end, the printing end comprising a substrate and a print head, the substrate being obliquely connected to the swing end, the print head being bonded to the substrate, the inclination angle of the substrate forming an angle not equal to 0 degrees with the horizontal angle; and

[0010] The rubber roller is connected to the plate body, and when the swing end is located at a first position, the print head abuts the tube body against the rubber roller, and when the swing end is located at a second position, the print head is away from the rubber roller.

[0011] In some embodiments, a movable groove is provided on the plate body, and the swing end is slidably connected in the movable groove.

[0012] In some embodiments, a connecting plate is further provided on the plate body, and an elastic member is connected between the connecting plate and the swing end.

[0013] In some embodiments, the swing end includes a shaft and a swing arm; the shaft is rotatably connected to the plate, and the swing arm is fixed on the shaft, and the end of the swing arm away from the shaft is movably connected to the movable groove.

[0014] In some embodiments, the elastic member is connected to the swing arm, and the elastic member includes a first spring and a second spring. Both ends of the first spring and the second spring are provided with hooks, one end of the first spring and the second spring is connected to the swing arm, and the ends of the first spring and the second spring are connected to the connecting plate.

[0015] In some embodiments, the connecting plate is provided with a first connecting hole and a second connecting hole respectively cooperating with the first spring and the second spring.

[0019] In some embodiments, the movable groove is obliquely arranged on the plate.

[0020] Compared with the prior art, the utility model provides a printing mechanism that can drive the base and the print head to move through the swing end. When the swing end is in the first position, the print head can abut against the rubber roller. Since the base and the print head are arranged obliquely on the swing end, the inclination angle of the print head can slightly bend the tube head when the print head is in contact with the rubber roller, causing the tube head to tilt up and out of the tube, assisting in guiding the direction of the tube out, and preventing the tube head from scratching the inner wall and side wall of the shell, thereby causing the tube to be blocked. When the swing end is in the second position, the print head is away from the rubber roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] In order to solve the technical problem in the prior art that the print head is set horizontally, which will cause the tube head to bend downward when the catheter moves inside the device, making it easy for the tube head to be scratched against the inner wall and side wall of the shell, thereby causing tube blockage, the utility model provides a printing mechanism, which can achieve that when the print head is attached to the rubber roller, the inclination angle of the print head can slightly bend the tube head, prompting the tube head to tilt up and out of the tube, assisting in guiding the direction of the tube outflow, and preventing the tube head from being scratched against the inner wall and side wall of the shell, thereby causing tube blockage.

[0030] It should be noted that the printing mechanism described in the present invention is used for but not limited to printing equipment, etc. For the sake of convenience, in the present invention, only the printing mechanism applied to the printing equipment is used as an example for explanation. The principles of the printing mechanism applied to other types of equipment are essentially the same as those applied to the printing equipment, and will not be repeated here.

[0031] See also Figure 2 and Figure 6 , Figure 2 and Figure 6 This is a structural diagram of a printing mechanism in an embodiment of the present invention, wherein the printing mechanism includes a plate 1, a swing end 2, a printing end 3 and a rubber roller 4;

[0032] The swing end 2 is rotatably connected to the base plate 31 and can be located at a first position or a second position;

[0033] The printing end 3 includes a substrate 31 and a print head 32. The substrate 31 is connected to the swing end 2 at an angle. The print head 32 is bonded to the substrate 31. The inclination angle of the substrate 31 forms an angle not equal to 0 degrees with the horizontal angle; and

[0034] The rubber roller 4 is connected to the plate 1 , and when the swing end 2 is at the first position, the print head 32 abuts the tube 6 against the rubber roller 4 , and when the swing end 2 is at the second position, the print head 32 is away from the rubber roller 4 .

[0035] In this embodiment, the base plate 31 and the print head 32 are displaced by the swing end 2. When the swing end 2 is in the first position, the print head 32 abuts the tube body 6 against the rubber roller 4. Since the base plate 31 and the print head 32 are installed obliquely on the swing end 2, the print head 32 and the rubber roller 4 can be more closely fitted, and the inclination angle of the print head 32 can slightly bend the tube head 6, prompting the tube head 6 to tilt up and out of the tube, and assist in guiding the direction of the tube outflow, thereby preventing the tube head 6 from rubbing against the inner wall and side wall of the shell, thereby causing the tube to be blocked. When the subsequent swing end 2 is in the second position, the print head 32 is away from the rubber roller 4, and at this time, the print head 32 no longer abuts against the rubber roller 4.

[0036] In one embodiment, see Figure 2 and Figure 3 The cam 22 is connected to the pivot plate 12 and the pivot plate 12 is connected to the pivot plate 12. The cam 22 is connected to the pivot plate 12 and the pivot plate 12 is connected to the pivot plate 12.

[0037] In this embodiment, the swing arm 22 is a Z-shaped plate, and one end of the swing arm 22 is sleeved on the shaft body 21 and swings with the rotation of the shaft body 21. The other end of the swing arm 22 is slidably connected to the movable groove 11, which is used to limit the swing arm 22, and a first spring 51 and a second spring 52 are arranged between the swing arm 22 and the connecting plate 12, wherein the first spring 51 and the second spring 52 play a corresponding limiting role. When the swing arm 22 is in the first position, it is used to squeeze the first spring 51 and the second spring 52, and squeezing occurs between the first spring 51 and the second spring 52. When the swing arm 22 is in the second position, the first spring 51 and the second spring 52 are in an expanded state, which is used to push the swing arm 22 to return quickly.

[0038] In one embodiment, see Figure 3 To improve the lamination efficiency between the print head 32 and the rubber roller 4,

[0039] The included angle is a, and 10°≤a≤30°, the angle a is 14°, and the movable groove 11 is obliquely arranged on the plate body 1 .

[0040] In this embodiment, the angle a formed by the tilt direction of the print head 32 and the horizontal direction is 14°. When the print head 32 is at this angle, it can effectively fit with the rubber roller 4, thereby preventing the tube head 6 from scratching the side wall of the cutter, thereby causing tube blockage.

[0041] In order to better understand the present invention, the following Figures 2 to 6 The technical solution of the present invention is described in detail: the base plate 31 is obliquely mounted on the swing arm 22, and the print head 32 is bonded to the base plate 31. The angle formed between the inclination direction of the print head 32 and the horizontal direction is a, and a is 14°, so that when the shaft 21 drives the swing arm 22 to move and is in the first position, the print head 32 can abut against the rubber roller 4, and at the same time make the print head 32 fit on the rubber roller 4, the inclination angle of the print head 32 can slightly bend the pipe head 6, prompting the pipe head 6 to tilt out of the pipe, and assist in guiding the direction of the pipe out, preventing the pipe head 6 from being scratched against the inner wall and side wall of the shell, thereby causing the pipe to be blocked. When printing is not required, the shaft 21 drives the swing arm 22 to move in the opposite direction and is in the second position. When the swing arm 22 is in the second position, the print head 32 is away from the rubber roller 4.

[0042] The specific embodiments of the present invention described above do not limit the scope of protection of the present invention. Any other corresponding changes and modifications made based on the technical concept of the present invention should be included in the scope of protection of the claims of the present invention.
