Description

Technical Field

[0001] This utility model relates to the technical field of inkjet printers for touch screen production, and in particular to an inkjet printer for touch screen production that is easy to disassemble and clean. Background Technology

[0002] Inkjet printers are used in the production of touch screens to print key information such as serial numbers, model numbers, and production dates on touch screen products. This is crucial for product traceability, after-sales service, and anti-counterfeiting.

[0003] Existing inkjet printers, such as the one disclosed in utility model patent CN218228368U, which is an easy-to-disassemble and clean inkjet printer for touch screen production, include mounting columns. Two sets of mounting columns are provided, each with a groove on one side surface. An adjustment component is installed within the groove, each component including sliders. The sliders are slidably mounted within the grooves. One set of sliders is fixedly connected to the other end of an adjustment rod, and the other set is fixedly connected to the other end of a mounting rod. An adjustment rod and a mounting rod are slidably mounted between the two sets of mounting columns via the adjustment component. One end of the adjustment rod has a locking interface, and the upper surface of the mounting rod has an installation groove containing a disassembly component. One end of the disassembly component has a locking plate, and the inkjet printer printhead body is held between the locking interface and the locking plate. This design allows for quick and easy disassembly of the printhead for cleaning, saving time and effort.

[0004] The touchscreen inkjet printer described in the aforementioned patent, while allowing disassembly of the printhead body, has the following drawbacks: Disassembly and assembly of the printhead body requires the activation of a motor; if the motor is damaged, disassembly and assembly cannot be completed, thus limiting its practicality. Furthermore, during operation, the screw rod tends to rotate on its own, causing it to extend and retract, which can lead to loosening of the clamping mechanism and insufficient sturdiness of the printhead body installation. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a touch screen production inkjet printer that allows for easy disassembly of the inkjet printer head body without relying on a motor, reducing usage limitations, making the inkjet printer head body more securely installed, and improving practicality through easy disassembly and cleaning.

[0006] Technical solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a touch screen production inkjet printer that is easy to disassemble and clean, comprising a crossbeam, a clamping mechanism, and a tightening mechanism. The inkjet printer nozzle body is detachably mounted on the crossbeam. The clamping mechanism includes two sets of arc-shaped clamping plates, each with a guide block fixed to its outer wall. A circular recess is formed at the center of the top of the crossbeam, with guide grooves on both the front and rear sides of the circular recess. The two sets of arc-shaped clamping plates are symmetrically and movably installed in the circular recess through the cooperation of the guide blocks and guide grooves. T-shaped sliders are fixed to the outer bottom of each of the two sets of guide blocks, and T-shaped sliding grooves are formed at the bottom of each of the two sets of guide grooves. The guide blocks are slidably installed in the guide grooves through the cooperation of the T-shaped sliders and T-shaped sliding grooves. A positioning hole is formed through the center of the bottom of the circular recess, and the inkjet printer nozzle body is inserted into the positioning hole. The two sets of arc-shaped clamping plates are tightened by the tightening mechanism. The clamping mechanism, comprising a drive shaft, is clamped on the outer walls of the front and rear sides of the inkjet printer head body. Both sides of the drive shaft's outer wall are provided with worm gear segments, the two sets of worm gear segments rotating in opposite directions. Two sets of support plates are symmetrically fixed on the right end of the crossbeam. The drive shaft is rotatably mounted on the two sets of support plates. A handle is fixedly sleeved in the middle of the drive shaft. Wing bolts are screwed onto both sets of support plates, the ends of which are pressed against the drive shaft. Two sets of transmission shafts are symmetrically rotatably mounted on the crossbeam. The left ends of the two sets of transmission shafts are rotatably connected to the left ends of two sets of guide grooves, respectively. Worm wheels are fixedly sleeved on the right ends of both sets of transmission shafts, and the two sets of worm wheels mesh with the two sets of worm gear segments. Cams are fixedly sleeved on both sets of transmission shafts, and the cams are located in the guide grooves. One end of each cam abuts against two sets of guide blocks. Two sets of arc-shaped clamping plates are symmetrically clamped on the outer walls of the front and rear sides of the inkjet printer head body under the clamping force of the cams.

[0008] Preferably, two sets of screw plates are symmetrically fixedly connected to the outer wall of the screw handle, and multiple sets of anti-slip rubber strips are provided at equal intervals at both the upper and lower ends of the two sets of screw plates.

[0009] Preferably, fastening pads are fixedly connected to the inner walls of both sets of arc-shaped clamps.

[0010] Preferably, a fastening rubber sleeve is fixedly provided on the inner wall of the positioning hole.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: During use, the tops of the arc-shaped clamping plate and the guide block are both horizontal with the top of the crossbeam. Through the cooperation of the T-shaped slider and the T-shaped groove, the guide block can slide in the guide groove, preventing the arc-shaped clamping plate from dislodging from the circular recess. When installing the inkjet printer head body, first insert the inkjet printer head body into the positioning hole to position it. Then loosen the wing bolts. By rotating the drive shaft, the drive shaft drives the transmission shaft to rotate through the meshing of the worm shaft section and the worm wheel. The transmission shaft then drives the cam to rotate, causing one end of the cam convex to rotate towards the guide block. This causes the cam to push the guide block inward, and the guide block pushes the arc-shaped clamping plate inward. When one end of the cam convex rotates inward to a horizontal position, the cam is pressed against the guide block. On the outside of the guide block, the arc-shaped clamping plate tightly holds the inkjet printer head body. Then, tighten the wing bolts to fix the drive shaft, thus completing the installation of the inkjet printer head body. During disassembly, by loosening the wing bolts and then rotating the drive shaft in the opposite direction, one end of the cam cam can rotate outward, so that the cam is no longer pressing against the guide block, thereby loosening the arc-shaped clamping plate. Then, the inkjet printer head body can be pulled out of the positioning hole to complete the disassembly. This allows the inkjet printer head body to be easily disassembled without relying on a motor, reducing usage limitations. Moreover, the meshing between the worm shaft section and the worm wheel has a self-locking effect, ensuring that the arc-shaped clamping plate will not loosen after clamping the inkjet printer head body, making the inkjet printer head body installation more secure and improving practicality.

[0018] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0019] Example

[0020] Please see Figures 1-5This utility model discloses a touch screen production inkjet printer that is easy to disassemble and clean. It includes a crossbeam 1, two sets of arc-shaped clamping plates 3, and a drive shaft 9. The inkjet printer head body 2 is detachably mounted on the crossbeam 1. Guide blocks 4 are fixed to the outer walls of both sets of arc-shaped clamping plates 3. A circular recess 6 is formed at the center of the top of the crossbeam 1, and guide grooves 8 are formed on both the front and rear sides of the circular recess 6. The two sets of arc-shaped clamping plates 3 are symmetrically and movably installed in the circular recess 6 through the cooperation of the guide blocks 4 and the guide grooves 8. T-shaped sliders 5 are fixed to the outer sides of the bottom ends of both sets of guide blocks 4. T-shaped sliding grooves 21 are formed at the bottom ends of both sets of guide grooves 8. The guide blocks 4 are slidably installed in the guide grooves 8 through the cooperation of the T-shaped sliders 5 and the T-shaped sliding grooves 21. A positioning hole 7 is formed through the center of the bottom end of the circular recess 6, and the inkjet printer head body 2 is inserted into the positioning hole 7. The two sets of arc-shaped clamping plates 3 are symmetrically clamped on the outer walls of the front and rear sides of the inkjet printer head body 2 by a clamping mechanism. Both sides of the outer wall of the drive shaft 9 are provided with worm shaft sections 12, and the two sets of worm shaft sections 12 rotate in opposite directions. Two sets of support plates 10 are symmetrically fixed on the right end of the crossbeam 1. The drive shaft 9 is rotatably mounted on the two sets of support plates 10. A screw handle 11 is fixedly sleeved in the middle of the drive shaft 9. Both sets of support plates 10 are screwed with wing bolts 16, and the ends of the wing bolts 16 are tightened against the drive shaft 9. Two sets of transmission shafts 13 are symmetrically rotatably mounted on the crossbeam 1. The left ends of the two sets of transmission shafts 13 are... The two sets of drive shafts 13 are rotatably connected to the left end of the two sets of guide grooves 8 respectively. The right end of each set of drive shafts 13 is fixedly fitted with a worm gear 14. The two sets of worm gears 14 mesh with the two sets of worm shaft sections 12 respectively. The two sets of drive shafts 13 are fixedly fitted with cams 15, and the cams 15 are located in the guide grooves 8. The convex end of each cam 15 rests on the two sets of guide blocks 4 respectively. The two sets of arc-shaped clamps 3 are symmetrically clamped on the front and rear outer walls of the inkjet printer head body 2 under the pressure of the cams 15.In use, the tops of the arc-shaped clamping plate 3 and the guide block 4 are both horizontal with the top of the crossbeam 1. Through the cooperation of the T-shaped slider 5 and the T-shaped groove 21, the guide block 4 can slide in the guide groove 8, preventing the arc-shaped clamping plate 3 from dislodging from the circular recess 6. When installing the inkjet printer head body 2, first insert the inkjet printer head body 2 into the positioning hole 7 to position it. Then loosen the wing bolt 16. By rotating the drive shaft 9, the drive shaft 9 drives the transmission shaft 13 to rotate through the meshing of the worm shaft section 12 and the worm wheel 14. The transmission shaft 13 then drives the cam 15 to rotate, causing the convex end of the cam 15 to rotate toward the guide block 4. This causes the cam 15 to push the guide block 4 to slide inward, and the guide block 4 to push the arc-shaped clamping plate 3 to move inward. When the convex end of the cam 15 rotates inward to a horizontal position, the cam 15 presses against the guide block 4. To the outside of block 4, the arc-shaped clamping plate 3 tightly holds the inkjet printer head body 2. Then, tighten the wing bolt 16 to fix the drive shaft 9, thus completing the installation of the inkjet printer head body 2. For disassembly, loosen the wing bolt 16 and rotate the drive shaft 9 in the opposite direction. This causes the convex end of the cam 15 to rotate outward, preventing the cam 15 from pressing against the guide block 4. This loosens the arc-shaped clamping plate 3, allowing the inkjet printer head body 2 to be pulled out of the positioning hole 7, completing the disassembly. This allows for easy disassembly of the inkjet printer head body without relying on a motor, reducing usage limitations. Furthermore, the meshing of the worm shaft section 12 and the worm wheel 14 has a self-locking effect, ensuring that the arc-shaped clamping plate 3 will not loosen after clamping the inkjet printer head body 2, making the inkjet printer head body installation more secure and improving practicality.

[0021] Two sets of screw plates 17 are symmetrically fixedly connected to the outer wall of the screw handle 11. Multiple sets of anti-slip rubber strips 18 are provided at equal intervals at both the upper and lower ends of the two sets of screw plates 17. When the hand holds the screw handle 11 to rotate the drive shaft 9, the screw plates 17 make it easier for the drive shaft 9 to rotate. The anti-slip rubber strips 18 at both ends of the screw plates 17 can effectively prevent the hand from slipping.

[0022] Both sets of arc-shaped clamping plates 3 have fastening pads 19 fixedly connected to their inner walls; by setting the fastening pads 19, the arc-shaped clamping plates 3 can clamp the inkjet printer head body 2 more tightly and reliably, avoiding slippage.

[0023] A fastening sleeve 20 is fixedly provided on the inner wall of the positioning hole 7; by providing the fastening sleeve 20, the inkjet printer head body 2 can be more securely inserted into the positioning hole 7.

[0024] This utility model discloses a touch screen production inkjet printer that is easy to disassemble and clean. Its working principle is as follows: During use, the two ends of the crossbeam 1 are fixedly welded to two sets of sliders in the prior art, replacing the original adjusting rod and mounting rod. The tops of the arc-shaped clamping plate 3 and the guide block 4 are both horizontal with the top of the crossbeam 1. Through the cooperation of the T-shaped slider 5 and the T-shaped groove 21, the guide block 4 can slide in the guide groove 8, preventing the arc-shaped clamping plate 3 from dislodging from the circular recess 6. When installing the inkjet printer head body 2, first insert the inkjet printer head body 2 into the positioning hole 7 to position it. Then loosen the wing bolt 16. By rotating the drive shaft 9, the drive shaft 9 drives the transmission shaft 13 to rotate through the meshing of the worm shaft section 12 and the worm wheel 14. The transmission shaft 13 then drives... When cam 15 rotates, the convex end of cam 15 rotates toward guide block 4, thereby pushing guide block 4 to slide inward. Guide block 4 then pushes arc-shaped clamp 3 to move inward. When the convex end of cam 15 rotates inward to a horizontal position, cam 15 presses against the outside of guide block 4, and arc-shaped clamp 3 tightly clamps the inkjet printer head body 2. Then, tighten the wing bolt 16 to fix the drive shaft 9, thus completing the installation of inkjet printer head body 2. During disassembly, by loosening the wing bolt 16 and then rotating the drive shaft 9 in the opposite direction, the convex end of cam 15 can rotate outward, so that cam 15 no longer presses against guide block 4, thereby loosening arc-shaped clamp 3. Then, the inkjet printer head body 2 can be pulled out of positioning hole 7, completing the disassembly.

[0025] This utility model discloses a touch screen production inkjet printer that is easy to disassemble and clean. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented. The inkjet printer printhead body in this utility model is referenced from a touch screen production inkjet printer that is easy to disassemble and clean, which belongs to the prior art. The other specific structures and working principles have been described in detail in the published patent, so they will not be repeated here.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
