[0025] In this embodiment, the dual-axis motor 21 is used to drive the rotating rod 22 to drive the gear 1 23 to rotate, and the meshing gear 2 32 causes the rotating rod 2 31 to rotate. The stirring rod 1 24 and the stirring rod 2 33 stir the paint to prevent precipitation. The stirring rod 2 33 drives the spiral rod 34 to rotate, clears the rotating hole, and guides the paint into the discharge pipe 35 in an orderly manner. Example

[0026] See also Figure 1-4On the basis of the first embodiment, the present invention provides a technical solution: preferably, the adjusting portion 6 includes a reciprocating screw 61, one end of the reciprocating screw 61 is connected to the output shaft on the other side of the dual-axis motor 21, and the other end of the reciprocating screw 61 is connected to a limiting plate 62, which prevents the reciprocating screw 61 from escaping from the screw slide 63. A screw slide 63 is sleeved on the reciprocating screw 61, and both ends of the screw slide 63 are connected to support arms 7, and a sliding groove is provided on the side where the two support arms 7 are close to each other. 8. Sliders 9 are connected to both sides of the outer wall of the tank body 1. The two slides 9 are slidably connected to the inner walls of the two slide grooves 8 respectively. A paint inlet pipe 10 is installed on the tank body 1. The paint inlet pipe 10 is connected to the existing material extraction pump to transport the paint into the tank body 1. The bottom of the two support arms 7 is connected to a receiving groove 11. The receiving groove 11 is used to receive the flowing and spilled paint. The inner wall of the receiving groove 11 is connected to a support plate 12. The support plate 12 is connected to a workbench 13 on the side close to the tank body 1, and a clamp 14 is installed on the workbench 13.

[0027] In this embodiment, the reciprocating screw 61 is driven by the dual-axis motor 21 to rotate, causing the reciprocating screw 61 to rise and fall back along the sleeve of the screw slide arm 63, driving the tank body 1 and the paint spray head 5 to rise and fall back, thereby covering the paper jam with paint.

[0028] The working principle is to connect the existing extraction pump through the paint inlet pipe 10 to transport the paint into the tank body 1 for storage, and clamp the paper jam on the workbench 13 through the clamp 14. The clamp 14 is a resettable clamping arm based on the torsion spring structure, which is a common tool in the prior art, so it is not described in detail. When the paper jam is clamped, the dual-axis motor 21 is started to make the rotating rod 22 drive the gear 1 23 to rotate. In this case, the gear 1 23 is respectively engaged with the gear 2 32 on both sides, so it can drive the gear 2 32 to rotate at the same time, and promote the two rotating rods 2 31 to rotate. At this time, the stirring rod 1 24 and the stirring rod 2 33 rotate alternately to stir the paint to prevent the paint from settling during spraying.

[0029] The rotation of the stirring rod 33 drives the screw rod 34 to rotate. The screw rod 34 is an auger structure, and the rod body is connected to a spiral piece. The screw rod 34 clears the rotary hole through the spiral piece and guides the paint into the discharge pipe 35 in an orderly manner to prevent the paint from clogging the rotary hole and the inner wall of the discharge pipe 35. The paint gathers in the collection plate 4 and is sprayed from the paint nozzle 5 onto the paper jam for spraying. The paint in the tank body 1 is always replenished through the paint inlet pipe 10, and there will be no problem of material shortage. The suction pump continues to work to ensure the pressure of paint spraying.

[0030] While the dual-axis motor 21 is implementing the above steps, the reciprocating screw 61 rotates accordingly, and the tank body 1 is limited by the slider 9 in the slide groove 8, so that the reciprocating screw 61 is lifted and lowered back and forth along the threaded contact port of the screw slide arm 63, thereby driving the tank body 1 to lift and lower back and forth. The limiting plate 62 prevents the reciprocating screw 61 from disengaging from the screw slide arm 63. During the reciprocating lifting of the tank body 1, the paint spray head 5 follows the reciprocating lifting, thereby covering the paper jam with paint to ensure the uniformity and integrity of the paint spraying. The receiving groove 11 is used to receive the flowing and spilled paint to reduce the pollution range of the working area.

[0031] The motor involved in this case can be a YCT series speed-regulating motor produced by Shanghai Fengxin Transmission Machinery Co., Ltd., and its supporting circuits and power supplies are also provided by the manufacturer; in addition, the circuits, electronic components and modules involved in this case are all existing technologies, which can be fully implemented by those skilled in the art without further elaboration, and the existing technical equipment in this case is not limited to one and any equipment model on the market that meets the characteristics of this case can be used as a substitute.
