Technical Field
[0001] The utility model relates to the technical field of printers, in particular to a printer trolley lifting device. Background Art
[0002] A printer is a computer output device used to print computer processing results onto a suitable medium. Three key indicators determine printer quality: print resolution, print speed, and noise. There are many different types of printers. They are categorized as impact printers and non-impact printers, depending on whether the printing element strikes the paper. They are also categorized as full-width printers and dot-matrix printers, depending on the structure of the printed characters. Serial printers and line printers are also categorized by the way a line of text is formed on paper.
[0003] The existing printer carriage can print objects at different heights by controlling its lifting and lowering. However, since the printer carriage has its own weight, it may be suddenly impacted by gravity during the lifting process, causing the printer carriage to deviate or have large color differences during the printing process. Therefore, a printer carriage lifting device is proposed to address the above problems. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Specific examples are given below.
[0022] See also Figure 1-5 As shown, a printer trolley lifting device includes a hanging seat 1, an electric guide rail 2 is symmetrically installed on the inner side of the hanging seat 1, a buffer box 4 is slidably arranged on the electric guide rail 2, a curved plate 11 is symmetrically installed on the middle part of the inner side of the buffer box 4, a smoothing mechanism is arranged on the inner side of the curved plate 11, a long slot 10 is opened on the buffer box 4, a connecting seat 13 is symmetrically installed on the top of the inner side of the buffer box 4, a matching component 1 is arranged on the connecting seat 13, fixed seats 7 are symmetrically installed on both sides of the buffer box 4, and a matching component 2 is arranged on the fixed seat 7. When the buffer box 4 needs to be lifted, the matching component 1 and the matching component 2 absorb and release the buffer box 4 and the gravity borne by the buffer box 4, so that the lifting process of the buffer box 4 is smoother, reducing the impact force caused by sudden lifting;
[0023] During operation, the electric guide rail 2 is used to control the lifting and lowering of the buffer box 4, and the curved plate 11 is used to limit the smoothing mechanism to achieve smooth lifting and lowering movement of the device. The long slot 10 is used to limit the smoothing mechanism during linear lifting. The cooperating component 1 provides a top-down pulling force for the buffer box 4 during the lifting process, and the cooperating component 2 provides a right-down pulling force for the buffer box 4 during the lifting process, so that the buffer box 4 improves its balance during the lifting process, thereby ensuring that it is lifted and lowered more smoothly to prevent deviations or large color differences.
[0024] Further, such as Figure 3 and Figure 4 As shown, the smoothing mechanism includes a curved groove 12 formed on the inner side of the curved plate 11, and a buffer rod 16 is symmetrically provided on the inner side of the buffer box 4 and between the two curved grooves 12. The two buffer rods 16 are hinged to each other, and rollers 18 are fixed to the bottom ends of both. Buffer rods 2 are symmetrically hinged to the two rollers 18. The two buffer rods 17 are hinged to each other, and a socket 19 is fixed at the junction.
[0025] During operation, when the electric guide rail 2 controls the buffer box 4 to move vertically, the angle between the two buffer rods 16 and the two buffer rods 17 will continue to increase or decrease. The curved groove 12 can control the change range of the angle, and the buffer rod 16 and the buffer rod 2 17 can be limited during the angle change. The roller 18 is used to achieve a clearance fit with the curved groove 12 at the connection between the buffer rod 16 and the buffer rod 2 17. As the angle between the buffer rod 16 and the buffer rod 2 17 changes, the roller 18 rolls on the inner side of the curved groove 12 to facilitate the smooth lifting and lowering of the buffer box 4.
[0026] Further, such as Figure 3 and Figure 4 As shown, a pull rod 20 is plugged into the socket 19, and the top of the pull rod 20 is fixed to the connection of the two buffer rods 16. The top of the pull rod 20 extends to the outside of the buffer box 4 and is fixedly connected to the hanging seat 1. A fixing rod 21 is fixedly installed on the outside of the connection of the two buffer rods 16. The end of the fixing rod 21 away from the buffer rod 16 is fixedly connected to the hanging seat 1, and the fixing rod 21 passes through the long slot 10;
[0027] During operation, in the process of the buffer box 4 being lifted and lowered, the connector 19 is used to limit the pull rod 20, and in the process of the angle between the buffer rod 16 and the buffer rod 2 17 being changed, the pull rod 20 is used to limit the longitudinal direction of the buffer rod 16, and the fixed rod 21 is used to limit the transverse direction of the buffer rod 16, so that in the process of the buffer box 4 being lifted and lowered, the buffer rod 1 16, the buffer rod 2 17 and the roller 18 are all lifted and lowered within the range of the curved groove 12 around the connection point between the fixed rod 21 and the buffer rod 16, and the pull rod 20 is used to keep the buffer box 4 unobstructed in the process of lifting and lowering.
[0028] Further, such as Figure 3 、 Figure 4 and Figure 5 As shown, the first mating component includes a second telescopic rod 14 fixedly mounted on the connecting seat 13, the second telescopic rod 14 sequentially passes through the first buffer rod 16 and the second buffer rod 17 and is fixedly connected to the plug seat 19, and the outer side of the second telescopic rod 14 is provided with a second spring 15;
[0029] The second mating component includes a telescopic rod 8 fixedly mounted on the fixing seat 7. The telescopic rod 8 extends to the outside of the buffer box 4 and is fixedly connected to the hanging seat 1. A spring 9 is sleeved on the outside of the telescopic rod 8.
[0030] During operation, as the buffer box 4 is lifted and lowered, the buffer box 4 drives the buffer rod 16 and the buffer rod 2 17 to contract and extend. The specific phenomenon of this extension and contraction is the change of the angle between the buffer rod 16 and the buffer rod 2 17 and the lifting and lowering of the connector 19. During this process, the roller 18 will roll on the inner side of the curved groove 12 as the buffer rod 16 and the buffer rod 2 17 extend and contract. The buffer box 4 drives the connecting seat 13 to move together, and the connecting seat 13 drives the telescopic rod 2 14 and the spring 2 15 to contract and extend. At the same time, the buffer box 4 drives the fixed seat 7 to move together, and the fixed seat 7 drives the telescopic rod 1 8 and the spring 1 9 to contract and extend together. The pulling force in opposite directions of the spring 19 and the spring 2 15 can make the buffer box 4 smoother during the lifting process, reducing the impact force caused by sudden lifting.
[0031] Further, such as Figure 1 and Figure 2 As shown, a loading plate 5 is fixedly provided on the outside of the buffer box 4, and a printer body 6 is hung on the loading plate 5;
[0032] During operation, the loading plate 5 is used to load the printer body 6, and the printer body 6 is used to realize the printing work. The movement of the buffer box 4 described above is that the buffer box 4 drives the loading plate 5, and the loading plate 5 drives the movement trajectory of the printer body 6.
[0033] Further, such as Figure 1 As shown, a moving block 3 is symmetrically mounted on the back of the buffer box 4, and the electric guide rail 2 is slidably connected to the moving block 3;
[0034] During operation, the moving block 3 is controlled by the electric guide rail 2 to move up and down, and the moving block 3 moves together with the buffer box 4.
