Description

Technical Field

[0001] The present invention relates to the technical field of engineering machinery drawing, and specifically relates to an inkjet nozzle for an engineering drawing plotter. Background Art

[0002] A plotter is a device specifically used for mechanical drawing. Its applications are extensive and can be used in fields such as mechanical drawing and engineering drawing. It can accurately draw the output information of a computer in the form of a graph. The plotter mainly relies on the reciprocating movement of the inkjet nozzle to achieve drawing.

[0003] The nozzle cartridge consists of a cartridge body for carrying the ink cartridge and an ink outlet head. When the ink cartridge inside the nozzle cartridge is used up, the lid on the nozzle cartridge needs to be opened. In the prior art, the lid of the nozzle cartridge is rotatably connected to the nozzle cartridge. When opening, the lid needs to be rotated upward. After the rotation is completed, the ink cartridge inside the nozzle cartridge needs to be pulled out. During the pulling out process of the ink cartridge, it needs to be shaken frequently to slowly loosen the connection between the ink cartridge and the nozzle cartridge. During the shaking process, the lid is prone to rotate back to its original position due to vibration. At this time, the staff needs to rotate the lid away again, resulting in low convenience and easily causing certain troubles to the replacement of the ink cartridge. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides an inkjet nozzle for an engineering drawing plotter.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an inkjet nozzle for an engineering drawing plotter, including a nozzle cartridge. Symmetrically arranged support blocks are fixedly connected to the top end of the nozzle cartridge. A support rod is rotatably connected between the support blocks. A top cover is rotatably connected to the support rod. An installation block is fixedly connected to the top end of the top cover. Symmetrically arranged resilient straps are fixedly connected to the back wall of the installation block. The bottom ends of the resilient straps are fixedly connected with limiting hooks. A connecting rod is fixedly connected to the back wall of the nozzle cartridge. A connecting groove is opened on the connecting rod;

[0006] An installation groove is opened on the nozzle cartridge. A blocking layer is fixedly connected inside the installation groove. Symmetrically arranged receiving grooves are opened on the nozzle cartridge at positions corresponding to the installation groove. A moving frame is slidably connected inside each of the receiving grooves. A pressure-receiving rod is fixedly connected to the side wall of each moving frame. A guiding block is fixedly connected to the bottom end of each moving frame. A rotating rod is rotatably connected between the moving frames. A winding roller is fixedly connected to the rotating rod. A driven gear is fixedly connected to the rotating rod at a position corresponding to the inside of one of the receiving grooves. A transmission rack is fixedly connected to the receiving groove corresponding to the driven gear at a position corresponding to the driven gear;

[0007] Both side walls of the nozzle box are rotatably connected to round rods, linkage rods are fixedly connected to the round rods, extrusion grooves are formed in the linkage rods, vertical blocks are slidably connected to positions adjacent to the linkage rods on the round rods, limiting rods are fixedly connected to the side walls of the vertical blocks, springs are fixedly connected to positions corresponding to the linkage rods on the side walls of the vertical blocks, and two limiting grooves are formed in both side walls of the nozzle box.

[0008] Specifically, the limiting hooks are all clamped inside the connection grooves.

[0009] Specifically, guiding grooves are formed at positions corresponding to the accommodating grooves on the nozzle box, the specific shapes of the guiding grooves and the guiding blocks are both T-shaped, and the guiding blocks are all slidably connected inside the corresponding guiding grooves.

[0010] Specifically, the blocking layer and the converging roller are both located inside the installation groove, and one end of the blocking layer is fixedly connected to the converging roller.

[0011] Specifically, one ends of the pressure-receiving rods all movably penetrate through the corresponding extrusion grooves, and the specific shapes of the moving frames are all L-shaped.

[0012] Specifically, the springs are all fixedly connected to the corresponding linkage rods, and one ends of the limiting rods are all slidably inserted into the top limiting grooves.

[0013] Specifically, sliding grooves are formed on the round rods, sliding blocks are fixedly connected to positions corresponding to the sliding grooves on the vertical blocks, and the sliding blocks are all slidably connected inside the corresponding sliding grooves.

[0014] Advantages of the present invention:

[0015] When it is necessary to remove the ink cartridge inside the nozzle box in the present invention, the limit of the linkage rod can be released, and then the two linkage rods are rotated. The rotation of the two linkage rods will cause the converging roller to move. During the movement of the converging roller, it will rotate due to the linkage of various components. At this time, the rotating and moving converging roller will wind up the blocking layer, thereby opening the top space of the nozzle box. This not only has high operation convenience, but also avoids the phenomenon that the cover shakes during the removal of the ink cartridge and affects the staff's removal of the ink cartridge. Moreover, the overall structure of the nozzle box is relatively simple, the use cost is low, and it is also convenient to remove the entire nozzle box from the guiding rod on the plotter, facilitating the maintenance work of the staff on the nozzle box.

Detailed implementation manners

[0025] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0026] As Figures 1-7 shown, an inkjet nozzle of an engineering drawing plotter according to the present invention includes a nozzle box 1. Symmetrically arranged support blocks 2 are fixedly connected to the top end of the nozzle box 1. A support rod 3 is rotatably connected between the support blocks 2. A top cover 4 is rotatably connected to the support rod 3. An installation block 5 is fixedly connected to the top end of the top cover 4. Symmetrically arranged tough straps 6 are fixedly connected to the back wall of the installation block 5. Limit hooks 7 are fixedly connected to the bottom ends of the tough straps 6. A connecting rod 8 is fixedly connected to the back wall of the nozzle box 1. A connection groove 9 is formed in the connecting rod 8;

[0027] The nozzle box 1 is provided with an installation groove 10. Inside the installation groove 10, a blocking layer 11 is fixedly connected. At the position corresponding to the installation groove 10 on the nozzle box 1, symmetrically arranged receiving grooves 12 are provided. Inside each of the receiving grooves 12, a moving frame 13 is slidably connected. On the side walls of the moving frame 13, pressure-receiving rods 14 are fixedly connected. At the bottom ends of the moving frame 13, guiding blocks 15 are fixedly connected. Between the moving frames 13, a rotating rod 16 is rotatably connected. On the rotating rod 16, a converging roller 17 is fixedly connected. At the position corresponding to the inside of one of the receiving grooves 12 on the rotating rod 16, a driven gear 18 is fixedly connected. At the position corresponding to the driven gear 18 in one of the receiving grooves 12, a transmission rack 19 is fixedly connected;

[0028] On both side walls of the nozzle box 1, round rods 20 are rotatably connected. On the round rods 20, connecting rods 21 are fixedly connected. On the connecting rods 21, extrusion grooves 22 are provided. At positions adjacent to the connecting rods 21 on the round rods 20, vertical blocks 23 are slidably connected. On the side walls of the vertical blocks 23, limiting rods 24 are fixedly connected. At positions corresponding to the connecting rods 21 on the side walls of the vertical blocks 23, springs 25 are fixedly connected. On both side walls of the nozzle box 1, two limiting grooves 26 are provided.

[0029] The limiting hooks 7 are all clamped inside the connecting grooves 9. The connection between the limiting hooks 7 and the connecting grooves 9 facilitates the positioning of the top cover 4. At the positions corresponding to the receiving grooves 12 on the nozzle box 1, guiding grooves 27 are provided. The specific shapes of the guiding grooves 27 and the guiding blocks 15 are both T-shaped. The guiding blocks 15 are all slidably connected inside the corresponding guiding grooves 27. The connection between the guiding blocks 15 and the guiding grooves 27 facilitates the guiding of the movement of the moving frame 13. The blocking layer 11 and the converging roller 17 are both located inside the installation groove 10. One end of the blocking layer 11 is fixedly connected to the converging roller 17, which facilitates the converging roller 17 to wind up the blocking layer 11 when rotating. One end of each pressure-receiving rod 14 movably penetrates through the corresponding extrusion groove 22. The specific shape of the moving frame 13 is L-shaped. When the connecting rod 21 rotates, the extrusion groove 22 will squeeze the pressure-receiving rod 14, thereby driving the moving frame 13 to move by squeezing the pressure-receiving rod 14. The springs 25 are all fixedly connected to the corresponding connecting rods 21. One end of each limiting rod 24 is slidably inserted inside the top limiting groove 26. The connection between the limiting rod 24 and the limiting groove 26 facilitates the positioning of the connecting rod 21. On the round rods 20, sliding grooves 28 are provided. At positions corresponding to the sliding grooves 28 on the vertical blocks 23, sliding blocks 29 are fixedly connected. The sliding blocks 29 are all slidably connected inside the corresponding sliding grooves 28. The sliding blocks 29 can prevent the vertical blocks 23 from rotating on the round rods 20.

[0030] During use, the two vertical blocks 23 can be simultaneously moved laterally. The movement of the vertical blocks 23 will drive the sliders 29 to slide inside the sliding grooves 28. At the same time, the vertical blocks 23 will also drive the limit rods 24 to disengage from the inside of the limit grooves 26. The movement of the vertical blocks 23 will also stretch the springs 25. At this time, the limit rods 24 are disengaged from the limit grooves 26, and the limit of the round rods 20 is released. The two round rods 20 can be rotated towards the back of the nozzle box 1 by the vertical blocks 23. The rotation of the round rods 20 will drive the linkage rods 21 to rotate. The rotation of the linkage rods 21 will cause the extrusion grooves 22 to squeeze the pressure-receiving rods 14. When the pressure-receiving rods 14 are squeezed, they will drive the moving frames 13 to slide inside the receiving grooves 12. The movement of the moving frames 13 will drive the guide blocks 15 to slide inside the guide grooves 27. At the same time, the movement of the moving frames 13 will jointly drive the rotating rods 16 and the winding rollers 17 to move. The movement of the rotating rods 16 will drive the driven gears 18 to move. The movement of the winding rollers 17 will squeeze the tightened blocking layer 11 into a wrinkled shape. When the driven gears 18 move a certain distance, they will be connected to the transmission racks 19. At this time, the continuously moving driven gears 18 will rotate due to the transmission racks 19. The rotation of the driven gears 18 will drive the rotating rods 16 and the winding rollers 17 to rotate during the movement. The rotation of the winding rollers 17 will wind up the wrinkled blocking layer 11. When the blocking layer 11 is completely wound up by the winding rollers 17, the winding rollers 17 and the moving frames 13 have moved to the other end inside the installation groove 10. At this time, the vertical blocks 23 also drive the limit rods 24 to rotate to the corresponding bottom limit groove 26 position. At this time, release the vertical blocks 23, and the springs 25 will drive the vertical blocks 23 and the limit rods 24 to reset. The reset limit rods 24 will be inserted into the bottom limit grooves 26. At this time, the positions of the round rods 20 and the pressure-receiving rods 14 are fixed again, and the space of the installation groove 10 is completely opened, and the ink cartridges inside the nozzle box 1 can be taken out and replaced. Not only is the operation highly convenient, but it also avoids the phenomenon that the lid affects the staff's removal of the ink cartridge due to shaking during the removal of the ink cartridge;

[0031] When it is necessary to separate the nozzle box 1 from the plotter, the two flexible straps 6 can be stretched. The stretching of the flexible straps 6 will drive the limit hooks 7 to move out of the connection grooves 9 on the connecting rods 8. At this time, the connection between the limit hooks 7 and the connection grooves 9 is disconnected, and the top cover 4 can be directly rotated upwards. The top cover 4 will rotate upwards through the support of the support rods 3. At this time, the nozzle box 1 can be taken out from the inside of the plotter, which is convenient for the staff to maintain the nozzle box 1.
