[0032] The two heating strips 8 are infrared heaters, electric heaters, etc. When working, one end of the bamboo is input into the box 2 by the left part of the driving mechanism 3 and passes through the middle channel of the synchronous belt assembly 5. At this time, the open rubber groove 7 is arranged around the bamboo, and the inner edge of the open rubber groove 7 contacts the surface of the bamboo. The driving mechanism 3 is paused, and the frame 4 drives the synchronous belt assembly 5 to rotate, driving the two plasma nozzles 6 on the upper and lower layers thereof to move horizontally relative to the bamboo. The plasma airflow ejected by the two plasma nozzles 6 processes the upper and lower surfaces of the bamboo. The open rubber groove 7 constrains the plasma airflow, reduces the diffusion of the plasma airflow into the space, and makes the plasma gas The flow acts more on the surface of the bamboo. The two heating strips 8 heat and dry the bamboo, and cooperate with the plasma airflow to treat the surface of the bamboo. When the two plasma nozzles 6 respectively perform plasma treatment on a certain width of the upper and lower surfaces of the bamboo, the synchronous belt assembly 5 pauses, the driving mechanism 3 drives the bamboo to step a distance, and the synchronous belt assembly 5 reverses to make the two plasma nozzles 6 perform plasma treatment on the next section of the bamboo. Compared with the existing technology, the bamboo is not blocked during the plasma treatment, so that the surface of the bamboo can be fully treated. The plasma airflow is constrained by the open rubber groove 7, the plasma flow is more concentrated, and the utilization rate is improved.

[0033] Specifically, the frame 4 includes a wheel frame 9, two wheel axles 10, multiple synchronous wheels 11 and a motor 12. The open rubber groove 7 is installed on the wheel frame 9. The two wheel axles 10 are rotatably installed on the wheel frame 9. Multiple synchronous wheels 11 are concentrically installed on the two wheel axles 10. The synchronous belt assembly 5 is set on the two synchronous wheels 11 located in the middle. The motor 12 is installed on the wheel frame 9. The output shaft of the motor 12 is connected to the wheel axle 10 in a transmission manner; the synchronous belt assembly 5 includes a ring groove synchronous belt 13, a ring groove synchronous belt 2 14 and multiple inserts 15.

Slots are set on the opposite surfaces of the ring groove synchronous belt 13 and the ring groove synchronous belt 2 14. The two ends of the multiple inserts 15 are detachably inserted into the slots of the ring groove synchronous belt 13 and the ring groove synchronous belt 2 14. Two of the multiple inserts 15 are provided with mounting holes for mounting the plasma nozzle 6. The two plasma nozzles 6 are respectively mounted on the two inserts 15 relatively through the mounting holes. It includes a synchronous belt 26, two machine bases 27, four pre-processors 28 and two adsorption members 29. The synchronous belt 26 is set on the two synchronous wheels 11 located in front of the open rubber groove 7.

Electromagnetic suction blocks are provided on the upper and lower parts of the adsorption component 29, and adsorption blocks matching the electromagnetic suction blocks of the adsorption component 29 are provided on the outer walls of the four pre-processors 28; it also includes a synchronization component 2 30 and two visual detectors 31. The synchronization component 2 30 is mounted on the two synchronization wheels 11 located behind the open rubber groove 7. The synchronization component 2 30 has the same structure as the synchronization belt component 5. The two visual detectors 31 are respectively installed on the upper and lower layers of the synchronization component 2 30. The two visual detectors 31 are respectively located behind the two plasma nozzles 6.

[0034] The two synchronous wheels 11 rotate to support the annular groove synchronous belt 13 and the annular groove synchronous belt 2 14, thereby driving the annular groove synchronous belt 13 and the annular groove synchronous belt 2 14 and the multiple inserts 15 to rotate, thereby driving the two plasma nozzles 6 to rotate, and the multiple inserts 15 close the space between the annular groove synchronous belt 13 and the annular groove synchronous belt 2 14 to reduce the upward and downward diffusion of the plasma airflow. Adjusting the positions of the two inserts 15 to be installed facilitates the adjustment of the relative positions of the two plasma nozzles 6 to adapt to bamboo materials of different widths. The four pre-processors 28 are different types of processing tools, which can be electric grinders or scrapers. The four pre-processors 28 are respectively adsorbed on the four electromagnetic suction blocks of the two adsorption parts 29. Two types of pre-processors 28 are arranged on the upper and lower layers of the synchronous belt 2 26. When pre-treating the bamboo material to be plasma-treated, the synchronous belt 26 rotates to drive the blocks of the two machine bases 27 to be inserted into the card slots of the two pre-treatment machines 28 respectively, and the corresponding electromagnetic suction blocks on the two adsorption parts 29 are released, so that the synchronous belt 26 drives the two machine bases 27 to move, so that the two machine bases 27 drive the two pre-treatment machines 28 to grind, polish or scrape the upper and lower surfaces of the bamboo material to improve the treatment effect. When the synchronous component 2 30 rotates, it drives the two visual detectors 31 to move relative to each other, so that the two visual detectors 31 detect the plasma treatment effect on the upper and lower surfaces of the bamboo material. When the detection is unqualified, the bamboo material is retreated, so that the two plasma nozzles 6 re-process the surface and lower surface of the bamboo material, realizing real-time detection and improving the surface treatment quality.

[0035] Example 2, as Figures 1 to 6 、 Figures 8 to 10 As shown, on the basis of embodiment 1, it also includes two slide rails 22, four sliders 23, four springs 1 24 and four support rods 1 25, the two slide rails 22 are installed in parallel on the base 1, the four sliders 23 are slidably installed on the two slide rails 22, the outer ends of the four springs 1 24 are connected to the base 1 through the bracket, the inner ends of the four springs 1 24 are respectively connected to the four sliders 2 23, the lower ends of the four support rods 1 25 are respectively rotatably connected to the four sliders 2 23, and the upper ends of the four support rods 1 25 are respectively rotatably connected to the four corners of the wheel frame 9; it also includes a slide Rail 16, two sliders 17, two rollers 18 and tension spring 19, the slide rail 16 is installed in the middle of the wheel frame 9, the slide rail 16 is parallel to the open rubber groove 7, the two sliders 17 are slidably installed on the slide rail 16, the two rollers 18 are respectively rotatably installed on the two sliders 17, and the two ends of the tension spring 19 are respectively connected to the two sliders 17; it also includes a photoelectric switch 20 and two reflective sheets 21, the photoelectric switch 20 is installed on the plasma nozzle 6, the two reflective sheets 21 are respectively installed on the end faces of the two rollers 18, and the two reflective sheets 21 match the photoelectric switch 20.

[0036] The motor 12 drives a wheel shaft 10 to rotate, and the wheel shaft 10 drives a synchronous wheel 11 and a synchronous belt assembly 5 thereon to rotate, thereby realizing the reciprocating drive of the synchronous belt assembly 5. Four springs 1 24 elastically support four sliders 23, and the four sliders 23 support the wheel frame 9 through four support rods 1 25. When the bent part of the bamboo enters between the two rollers 18, the bent part will drive the slide rail 16 to change its posture through the two rollers 18. The force generated by the change in the posture of the slide rail 16 acts on the wheel frame 9, causing the posture of the wheel frame 9 to change. The wheel frame 9 drives the posture of the four support rods 1 25 to change, thereby causing the four sliders 23 to move along the two slide rails 22. The expansion and contraction amount of the four springs 1 24 changes adaptively to improve adaptability. When the bamboo passes through the middle channel of the synchronous belt assembly 5, the two rollers 18 respectively roll with the two side wall surfaces of the bamboo. Dynamic connection, the elastic force of the tension spring 19 keeps the two rollers 18 pressed against the two side walls of the bamboo, so that the rolling pressure can be maintained when the width of the bamboo changes. When the bamboo bends or twists up and down, the slide rail 16 drives the wheel frame 9 to adaptively adjust its posture, thereby maintaining the relative distance between the two plasma nozzles 6 and the bamboo; the photoelectric switch 20 is electrically connected to the controller of the motor 12. Since the two rollers 18 drive the two reflective sheets 21 to always be located on the outside of the bamboo, when the plasma nozzle 6 moves to the outside of the bamboo, the photoelectric switch 20 receives the photoelectric signal emitted by the reflective sheet 21, so that the photoelectric switch 20 generates a steering signal. After receiving the steering electrical signal, the controller of the motor 12 starts to reverse, so that the moving range of the two plasma nozzles 6 is automatically limited to between the two reflective sheets 21, and automatically adapts to bamboo of different widths.

[0037] Example 3, as Figures 1 to 3 、 Figure 5 and Figure 7As shown, on the basis of Example 1, the driving mechanism 3 includes two sliders 32, two support rods 2 33, a roller frame 1 34, a roller group 1 35, a positive screw 36, a motor 2 37, two sliders 4 38, two support rods 3 39, a roller frame 2 40, a roller group 2 41, a reverse screw 42 and a transmission assembly 43. The two sliders 3 32 are relatively slidably mounted on the left side wall of the base 1, the lower ends of the two support rods 2 33 are respectively rotatably connected to the two sliders 3 32, the roller frame 1 34 is movably connected to the base 1, the upper ends of the two support rods 2 33 are respectively rotatably connected to the two ends of the roller frame 1 34, the roller group 1 35 is rotatably mounted on the roller frame 1 34, the roller group 1 35 is used to clamp and transport bamboo materials, and the positive screw 36 is rotatably mounted on On the base 1, the positive screw 36 is rotatably screwed with the two sliders 32, the motor 2 37 is installed on the base 1, and the output shaft of the motor 2 37 is transmission-connected with the positive screw 36. The two sliders 4 38 are relatively slidingly installed on the right side wall of the base 1. The lower ends of the two support rods 39 are respectively rotatably connected with the two sliders 4 38, and the upper ends of the two support rods 39 are respectively rotatably connected with the two ends of the roller frame 2 40. The roller frame 2 40 is movably connected to the base 1. The roller group 2 41 is rotatably installed on the roller frame 2 40. The roller group 2 41 is used to clamp and transport bamboo. The reverse screw 42 is rotatably installed on the base 1. The reverse screw 42 is rotatably screwed with the two sliders 4 38. The positive screw 36 is transmitted to the reverse screw 42 through the transmission assembly 43.

[0038] The bamboo material passes through roller group 1 35, and roller group 1 35 transports the bamboo material to roller group 2 41, so that roller group 1 35 and roller group 2 41 respectively roll and clamp the two ends of the bamboo material and transport it backward in steps. Motor 2 37 drives the positive screw 36 to rotate, and the positive screw 36 drives the two sliders 32 to move through the thread action, so that one slider 32 approaches roller frame 1 34 and the other slider 32 moves away from roller frame 1 34, so that one support rod 2 33 stands upright and the other support rod 2 33 tilts and falls down, thereby causing roller frame 1 34 to tilt, thereby causing roller frame 1 34 to tilt. Group 1 35 twists one end of the bamboo, and at the same time, the positive screw 36 drives the reverse screw 42 to rotate through the transmission assembly 43. The thread rotation direction of the reverse screw 42 is opposite to that of the positive screw 36. Similarly, the rotation of the reverse screw 42 drives the two sliders 4 38 to move, driving the two support rods 3 39 to tilt or vertically, thereby causing the roller frame 2 40 and the roller frame 1 34 to twist in the opposite direction, causing the roller group 2 41 to twist the other end of the bamboo in the opposite direction, causing the bamboo fibers in the part of the bamboo between the open rubber grooves 7 to be slightly twisted and staggered, thereby improving the depth and quality of the plasma treatment.

[0039] like Figures 1 to 13As shown, a plasma surface treatment device for bamboo surface of the present invention, when it is working, first one end of the bamboo material is input into the box body 2 by the roller group 1 35 and passes through the middle channel of the synchronous belt assembly 5, and the two rollers 18 roll and clamp the two side edges of the bamboo material. At this time, the open rubber groove 7 is arranged around the bamboo material, and the inner edge of the open rubber groove 7 is in contact with the surface of the bamboo material. The roller group 1 35 and the roller group 2 41 are paused, and then the motor 12 runs to drive the synchronous belt assembly 5 to rotate, driving the two plasma nozzles 6 on the upper and lower layers thereof to move laterally relative to the bamboo material. The plasma airflow ejected by the two plasma nozzles 6 processes the upper and lower surfaces of the bamboo material, and the open rubber groove 7 constrains the plasma airflow, reduces the diffusion of the plasma airflow into the space, so that the plasma airflow acts more on the surface of the bamboo material, and the two heating strips 8 dry and heat the upper and lower surfaces of the bamboo material, and then the roller group 1 35 and the roller group 2 Group 2 41 twists the two ends of the bamboo material, causing the bamboo fibers in the portion of the bamboo material located between the open rubber grooves 7 to be slightly twisted and staggered, thereby improving the depth and quality of the plasma treatment. When the two plasma nozzles 6 respectively perform plasma treatment on a certain width of the upper and lower surfaces of the bamboo material, the synchronous belt assembly 5 pauses, and the drive mechanism 3 drives the bamboo material to step a distance. The two visual detectors 31 detect the plasma treatment effects on the upper and lower surfaces of the bamboo material. When the detection is unqualified, roller group 1 35 and roller group 2 41 retract the bamboo material, causing the two plasma nozzles 6 to process the surface and lower surface of the bamboo material again. Finally, when the detection is qualified, the bamboo material steps a distance, and the synchronous belt assembly 5 reverses to cause the two plasma nozzles 6 to perform plasma treatment on the next section of the bamboo material. When the bamboo material is twisted, the wheel frame 9 is driven by the two rollers 18 and the slide rail 16 to adaptively adjust its posture.

[0040] The main functions achieved by the present invention are:

[0041] 1. The bamboo material is not blocked during plasma treatment, so the surface of the bamboo material can be fully treated;

[0042] 2. The plasma flow is constrained by the open rubber groove 7, making the plasma flow more concentrated and improving the utilization rate;

[0043] 3. The frame 4 is a suspended structure that can adapt to the bending of the bamboo.

[0044] 4. The movement range of the two plasma nozzles 6 is automatically limited to between the two reflective sheets 21, automatically adapting to bamboos of different widths;

[0045] 5. The two machine bases 27 drive the two pre-processing machines 28 to grind, polish or scrape the upper and lower surfaces of the bamboo to improve the processing effect;

[0046] 6. Able to transport and twist bamboo to improve the depth and quality of plasma treatment.
