The inkjet head is arranged directly above the material conveying table through a bracket to perform inkjet printing operations on the passing materials. However, the fixed inkjet head here is inconvenient to adjust, and once adjusted, the corresponding inkjet detection device also needs to synchronously adjust its position, which is very cumbersome.

[0003] In addition, when the inkjet head is working, due to the impact force generated by the spraying pump pressure feeding on the inkjet head, the inkjet head will generate high-frequency vibration on the installation bracket. Continuous industrial control may cause the bracket to deform. Especially for the high-precision operation of inkjet printing, this problem will lead to unqualified inkjet printing quality and reduce the yield rate.

Detailed Implementation Manner

[0028] Please refer to Figures 1-6 , the present utility model provides a technical solution: an inkjet device for a soft-pack lithium battery film punching machine, including a beam frame 1, and an inkjet head 2 facing the material conveying table 4 is suspended at the bottom of the beam frame 1;

[0029] A height adjustment mechanism for driving the up and down distance adjustment of the spray head 2 is provided on the beam frame 1. A longitudinal movement mechanism is installed on the beam frame 1. The height adjustment mechanism is installed on the moving end of the longitudinal movement mechanism. The spray head 2 is installed on the displacement end of the height adjustment mechanism through a spray head frame 17. A plurality of the spray heads 2 are provided on the spray head frame 17. Each spray head 2 is firmly installed through a shock-absorbing clamp block assembly. The shock-absorbing clamp block assembly includes two butted spray head clamp blocks 20. The two spray head clamp blocks 20 are hinged and covered through a clamp block rotating shaft 22. A clamp block screw hole 21 for cooperating with a bolt for fastening is provided on the opposite side of the hinge of the spray head clamp block 20. A rod hole 23 for clamping the outer wall of the spray head 2 is surrounded and provided in the middle of the two spray head clamp blocks 20. A plurality of shock-absorbing pads 25 are installed on the inner wall of the rod hole 23. A spray rod fastening ring 24 is fastened on the outer wall of the spray head 2. The spray head 2 passes through the rod hole 23. The spray rod fastening ring 24 is pressed against the top end surface of the spray head clamp block 20 through a reed pad 3.

[0030] During operation, the beam frame 1 drives the spray head 2 on the spray head frame 17 to move back and forth through the longitudinal movement mechanism. Among them, the entire spray head frame 17 can adjust the height of the spray head 2 relative to the material conveying table 4 through the height adjustment mechanism. The setting of the spray head clamp block 20 can facilitate the clamping and fastening of the spray head 2. When the spray head 2 needs to be replaced, first loosen the bolt from the clamp block screw hole 21, and then rotate and open the two spray head clamp blocks 20, then the spray head 2 can be directly taken out. It should be noted here that the spray rod fastening ring 24 is fastened on the outer wall of the spray head 2. After the spray head 2 and the spray rod fastening ring 24 are installed into one body, they are clamped by the two spray head clamp blocks 20. The spray rod fastening ring 24 can adopt spiral or friction clamping or other methods. Here, the spray rod fastening ring 24 mainly plays a limiting role. In order to ensure that the depth of the spray head 2 penetrating into the rod hole 23 is always the same, when multiple spray heads 2 are working, their bottom heights are the same. Here, the shock-absorbing pad 25 can, on the one hand, absorb shock, and on the other hand, provide a clamping margin for spray heads 2 with different diameters. And the reed pad 3 here mainly provides a buffer for the spray head 2 and the spray head clamp block 20. When the spray head 2 is working, it has pump pressure. The spray head 2 together with the spray rod fastening ring 24 will have an obvious downward pressure on the spray head clamp block 20. If it is a completely rigid connection, it may cause high-frequency tremors of the spray head clamp block 20, or cause mechanical wear of the metal of the connection structure between the spray head clamp block 20 and the spray head frame 17. In the long term, it will cause the angle of the spray head clamp block 20 to tilt and reduce the service life. Therefore, the reed pad 3 here can provide a good impact buffer, offset the pump pressure impact generated when the spray head 2 starts and stops working, and slow down high-frequency vibration and mechanical wear.

[0031] Among them, the longitudinal movement mechanism includes a longitudinal movement frame 10 fixed to the bottom of the beam frame 1. Longitudinal movement lead screws 11 are rotatably installed at the front and rear ends of the longitudinal movement frame 10. A longitudinal movement motor 12 for driving the rotation of the longitudinal movement lead screws 11 is installed at one end of the longitudinal movement frame 10. The top end of the longitudinal movement slider frame 13 is slidably clamped on the longitudinal movement frame 10, and the longitudinal movement lead screws 11 are threadedly passed through the longitudinal movement slider frame 13;

[0032] Among them, the height adjustment mechanism includes a height adjustment motor 14. The height adjustment motor 14 is installed on the front panel in the middle of the longitudinal movement slider frame 13. The motor shaft of the height adjustment motor 14 is fixedly connected with a vertically arranged height adjustment lead screw 15. A height adjustment slider frame 16 is vertically slidably installed on the front panel at the bottom of the longitudinal movement slider frame 13. The height adjustment lead screw 15 is threadedly passed through the top of the height adjustment slider frame 16. The nozzle holder 17 is horizontally and fixedly installed at the bottom position of the height adjustment slider frame 16;

[0033] During operation, when it is necessary to adjust the height of the spray head 2, the height adjustment motor 14 is driven to work. The height adjustment motor 14 drives the height adjustment lead screw 15 to rotate. The height adjustment slider frame 16 is vertically slidably limited on the longitudinal movement slider frame 13. The height adjustment lead screw 15 is in threaded fit connection with the height adjustment slider frame 16. Then, the height adjustment slider frame 16 will perform a vertical sliding action up and down according to the rotation direction of the height adjustment lead screw 15. When it is necessary to adjust the front and rear positions of the spray head 2, the longitudinal movement motor 12 is driven to work. Similarly, the longitudinal movement motor 12 drives the longitudinal movement lead screws 11 to rotate. The longitudinal movement slider frame 13 slides back and forth along the longitudinal movement frame 10. Then, the longitudinal movement slider frame 13 drives the nozzle holder 17 to move back and forth as a whole through the height adjustment slider frame 16. The materials on the material conveying table 4 are conveyed left and right. Therefore, the spray head 2 that can move back and forth and up and down can be used to realize the spraying adjustment at different azimuth heights.

[0034] Among them, the reed gasket 3 includes an arc-shaped flat gasket 30, an inclined reed 31 and a pressing arc piece 32. The arc-shaped flat gasket 30 is fan-shaped. The inclined reed 31 is located on the outer ring edge of the arc-shaped flat gasket 30 and curls inwards from the outside. The pressing arc piece 32 is located on the inner ring edge of the arc-shaped flat gasket 30 and turns outwards from the inside. A plurality of the reed gaskets 3 are arranged between the spray rod fastening ring 24 and the nozzle clamping block 20. When the reed gasket 3 is vertically pressed downwards, the inclined reed 31 is elastically compressed and deformed, and the pressing arc piece 32 inclines towards the inner circle;

[0035] During operation, the inclined reed 31 provided can generate elastic deformation, and the arc-shaped flat gasket 30 is the force-bearing surface. The connection between the arc-shaped flat gasket 30 and the inclined reed 31 is higher than the connection between the arc-shaped flat gasket 30 and the pressing arc piece 32. Such as Figure 7 、 Figure 8As shown, when the spray head 2 together with the spray rod fastening ring 24 impacts the nozzle holder block 20, the inclined spring plate 31 deforms, and the arc-shaped flat pad 30 will press against the abutting arc plate 32 to tilt upwards. At this time, the tilted abutting arc plate 32 further clamps the outer wall of the spray head 2 located in the rod hole 23. Therefore, the provided spring plate pad 3 can not only perform shock absorption and buffering through the inclined spring plate 31, but also impact and clamp the spray head 2 through the provided abutting arc plate 32, further reducing the vibration of the spray head 2 and the nozzle holder block 20.

[0036] Among them, a vision recognition sensor 18 for acquiring images of the spraying position is installed on the height adjustment slider frame 16;

[0037] During operation, the vision recognition sensor 18 installed on the height adjustment slider frame 16 can ensure followability. When the position of the spray head 2 changes, it can dynamically track and acquire images in real time, which is more convenient and does not require re-adjusting the position.

[0038] Among them, a plurality of installation slider frames 26 for installing the nozzle holder blocks 20 are horizontally slidably installed on the nozzle holder 17, and fastening bolts 27 for pressing against the nozzle holder 17 are threaded through the installation slider frames 26;

[0039] During operation, the provided installation slider frames 26 can drive the nozzle holder blocks 20 to horizontally move and adjust the spacing position, and are fastened and limited by the fastening bolts 27.
