Description

Technical Field

[0001] The utility model relates to the field of printing machines, in particular to a double-nozzle adjustment and positioning device for a direct-injection printing machine. Background Art

[0002] The principle of direct printing is to spray the printing ink droplets from the small holes on the printer nozzle to the specific position on the printing medium, thereby forming the desired printed image. At present, in order to meet the customer's requirements for the function and speed of inkjet printers, multiple printing nozzles are usually installed on an inkjet printer. In order to achieve high-quality and ideal printing quality, the horizontal and vertical positions of multiple nozzles need to be relatively consistent, and the installation and positioning accuracy of the nozzles is extremely high. Relying solely on the processing accuracy control of parts will increase the processing cost.

An adjusting screw B 248 with the outer end connected to the threaded hole is inserted into the through hole B 246.

[0021] An auxiliary threaded hole B 249 is provided at the other end of support B 245. An auxiliary screw B 250 is installed in the auxiliary threaded hole B. The outer end of the auxiliary screw B presses against the side of square frame seat B 241. The outer end of auxiliary screw A 230 presses tightly against the side of the adjusting plate 224, forming a combined locking effect with the adjusting screw A 228. Support B 245 is a square seat, and the length of the square seat matches the length of square frame seat B 241.

[0022] The edge parts of the square box seat A 231 are all provided with assembly grooves, and the long hole A 221 is arranged at the assembly groove. The assembly groove can reduce the connection length of the screw and ensure the fastening effect of the screw pair.

[0023] The usage method of the adjustment and positioning device in this embodiment is as follows: Loosen the vertical screw 26 to release the fixation of the square box seat B 241, and then rotate the adjustment screw B 248. The outer end of the adjustment screw A 228 rotates in the threaded hole A 225 on the side of the square box seat A 231. Push and pull the square box seat A through the thread, and the square box seat A 231 rotates around the vertical axis B 244 together with the nozzle A 22 and slightly moves horizontally along the vertical axis B 244 to perform horizontal fine adjustment on its position. During the fine adjustment process, the long hole B 242 ensures that there is enough adjustment margin. After the adjustment is completed, tighten the vertical screw 26 again, and screw the auxiliary screw B 250 to press its outer end against the side of the square box seat B 241. The adjustment screw B 248 and the auxiliary screw B 250 form a combined locking effect, and the position of the nozzle B 24 has high stability after adjustment and is not easy to loosen.

[0024] Embodiment 2, see the appendix Figures 1-6 In this embodiment, on the basis of Embodiment 1, the nozzle A 22 is designed to be installed in the square box seat A 231. Two long holes A 221 are symmetrically arranged at both ends of one side of the square box seat A. A vertical screw 26 threadedly connected to the trolley bottom plate 21 is installed in the long hole A 221. There is a certain movement margin between the long hole A 221 and the vertical screw 26. A round hole 222 is arranged in the middle of the other side of the square box seat A 231. A vertical shaft A 223 that rotates and fits into the round hole is arranged on the trolley bottom plate 21. The round hole 222 can rotate on the vertical shaft A 223. An adjustment plate 224 is arranged on the outer side of the end of the square box seat A 231. A threaded hole A 225 is arranged at the end of the adjustment plate, and a support A 226 is arranged on the trolley bottom plate 21 outside the adjustment plate 224. A through hole A 227 is arranged at one end of the support A 226. An adjustment screw A 228 with its outer end connected to the threaded hole A 225 is inserted into the through hole A. The size of the through hole A 227 is larger than the size of the adjustment screw A. During the process of screwing the adjustment screw A 228, it has a certain movement margin in the through hole A 227.

[0025] An auxiliary threaded hole A 229 is arranged at the other end of the support A 226. An auxiliary screw A 230 is installed in the auxiliary threaded hole A 229. The outer end of the auxiliary screw A abuts against the side of the adjustment plate 224 to form a combined locking effect with the adjustment screw A 228. The auxiliary screw A 230 is used to abut against the side of the adjustment plate 224; the support A 226 is a T-shaped seat, and the through hole A 227 and the auxiliary threaded hole A 229 are both arranged on the boss of the T-shaped seat.

[0026] Assembly grooves are provided at the edge portions of the square frame seat A 231, and the long hole A 221 is provided at the assembly groove. Designing the assembly groove can reduce the connection length of the screw and ensure the fastening effect of the screw pair.

[0027] The usage method of the adjustment and positioning device in this embodiment is as follows: Loosen the vertical screw 26 to release the fixation of the square frame seat A 231, and then rotate the adjustment screw A 228. The outer end of the adjustment screw A 228 rotates in the threaded hole A 225 of the adjustment plate 224. By pushing and pulling the adjustment plate 224 through the thread, the adjustment plate 224 together with the square frame seat A 231 rotates around the vertical shaft A 223 to perform horizontal fine adjustment of its position. During the fine adjustment process, the long hole A 221 ensures that there is sufficient adjustment margin. After the adjustment is completed, tighten the vertical screw 26 again, and screw the auxiliary screw A 230 to press its outer end against the side surface of the adjustment plate 224. The adjustment screw A 228 and the auxiliary screw A 230 form a combined locking effect. After the position of the nozzle A 22 is adjusted, it has high stability and is not easy to loosen.
