DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the specific implementation methods of the present invention or the technical solutions in the prior art, the drawings required for use in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are some implementation methods of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative work.

[0025] like Figure 2 As shown, the two ends of a supporting longitudinal beam 1 are respectively vertically connected to the middle sections of two supporting cross beams 2, forming an I-shaped supporting profile together. The jet shield 3 is an arched metal bent plate, which is fixedly connected to the supporting cross beam 2 by bolts. The supporting profile and the jet shield 3 together form a second accommodating space with an opening below. A jet head is slidably connected to the supporting longitudinal beam 1 through a connecting block 4, and the nozzle direction of the jet head is away from the jet shield 3. In a preferred embodiment, the spray head is a rotating jet head 5, which has multiple nozzles, and during the jetting process, the multiple nozzles rotate to jet, so that the jetting area is larger. The number of rotating jet heads 5 can be one or more, and the specific number can be configured according to actual needs. The corresponding number of connecting blocks 4 are slidably connected to the groove of the supporting longitudinal beam 1, and its installation position can be set according to actual working conditions.

[0026] refer to Figure 1 , Figure 3 and Figure 4, the two ends of the protective cover upper plate 6 are fixedly provided with protective cover side plates 7, the protective cover side plates 7 extend downward vertically relative to the protective cover upper plate 6, and the two ends of the protective cover upper plate 6 where the protective cover side plates 7 are not provided are respectively the tray inlet end for the tray to enter and the tray outlet end for the tray to move out, and the first accommodation space formed by the dust removal protective cover formed by the protective cover side plates 7 and the protective cover upper plate 6 is used for passing the tray and removing dust from the tray. It should be noted that the two protective cover side plates 7 and the protective cover upper plate 6 can be an integrally formed structure.

[0027] The upper plate 6 of the protective cover is provided with a brush 8 extending vertically downward relative to the upper plate of the protective cover at the tray inlet and the tray outlet. During the process of the tray entering and moving out, the brush 8 will come into contact with the surface of the tray and filter out the larger particles on the surface of the tray. It should be noted that the brush 8, as a dust removal component, plays a preliminary dust removal function and can also be replaced by other components with cleaning functions such as soft rubber plates and scrubbing wheels, without specific restrictions. Below the upper plate 6 of the protective cover at the tray inlet, a static removal component is provided. In this embodiment, the static removal component is an ion wind rod 9. The ion wind rod 9 has the characteristics of rapid neutralization of static electricity and stable and safe working performance. When the tray enters and passes under the ion wind rod 9, static removal treatment is performed.

[0028] A rectangular opening is provided on the upper plate 6 of the protective cover, and the lower surface of the supporting beam 2 is fixedly connected to the outer peripheral portion of the opening, so that the jet unit is fixed on the upper plate 6 of the protective cover, and the first accommodating space is connected to the second accommodating space.

[0029] An inner cover body is provided below the upper plate 6 of the protective cover. The inner cover body has openings at the upper end and the lower end. The opening at the upper end is fixedly abutted against the opening of the upper plate 6 of the protective cover. An exhaust pipe 10 is provided on one side of the inner cover body. The exhaust pipe 10 passes through the side plate 7 of the protective cover and is connected to the outside. The rotating nozzle head 5 passes through the opening of the inner cover body and is placed in the inner cover body. The bottom of the inner cover body is used to pass a tray. The rotating nozzle head 5 blows air to the tray, and the blown gas and dust are discharged to the external space through the exhaust pipe 10.

[0030] like Figure 4 , Figure 5 and Figure 6In some embodiments, the inner cover body includes a first cover body 11 and a second cover body 12, both of which are hollow cover-shaped structures formed by sheet metal and have upper and lower openings, the first cover body 11 is sleeved on the outside of the second cover body 12, the upper end opening of the first cover body 11, the upper end opening of the second cover body 12 and the opening of the upper plate 6 of the protective cover are all abutted and connected, the outer peripheral surfaces of the first cover body 11 and the second cover body 12 are arranged at intervals, and a gap space is formed between the first cover body 11 and the second cover body 12, the first cover body 11 is connected to the exhaust pipe 10 through a diameter change, the rotating nozzle 5 passes through the opening of the upper plate 6 of the protective cover and is placed in the second cover body 12, and the tray is blown through the second cover body 12, and the blown gas passes through the gap space 13 between the first cover body 11 and the second cover body 12, and is discharged to the external space through the exhaust pipe 10, and the external space can be a negative pressure dust collection pipe in the workshop.

[0031] In some preferred embodiments, the first cover body 11 is shaped like a rectangle with openings at the upper and lower ends, and the second cover body 12 is shaped like a pyramid with openings at the upper and lower ends. The lower end of the second cover body 12 extends toward the outer peripheral surface of the first cover body 11 relative to the upper end, that is, the second cover body 12 is narrow at the top and wide at the bottom, which is beneficial for a larger and more uniform airflow ejection area during the blowing process, thereby more thorough dust removal of the tray.

[0032] like Figure 5 As shown, in some preferred embodiments, the height of the lower edge of the protective cover side panel 7 relative to the ground is lower than the height of the lower edge of the first cover body 11 relative to the ground, the height of the lower edge of the second cover body 12 relative to the ground is higher than the height of the lower edge of the first cover body 11 relative to the ground, and the lower edge of the first cover body 11 has a first bending portion 1101 bent outwardly along the circumferential direction, and the lower edge of the second cover body 12 has a second bending portion 1201 bent inwardly along the circumferential direction. The gas passes through the rotating nozzle 5 through the second cover body 12 to blow air to the tray, and the second bending portion 1201 guides the gas toward the center of the tray, thereby preventing excessive diffusion of the gas, thereby reducing the force of the blowing, and the gas passing through the tray is guided to the gap space 13 by the first bending portion 1101, and is discharged to the external environment through the exhaust pipe 10, wherein the first bending portion 1101 serves to expand the air collection area. The above structural design is conducive to the flow of gas, increases the dust removal efficiency, and during the dust removal process, dust will not enter the space outside the first cover body 11, thereby ensuring that other components such as the brush 8 and the ion wind rod 9 will not be affected by the dust.

[0033] like Figures 1 to 6In some embodiments, a detection port 14 is also provided on one side of the exhaust pipe 10. The detection port 14 is a tubular structure and is connected to the exhaust pipe 10. A wind speed detector 15 is provided on the detection port 14. The wind speed detector 15 can detect the air flow rate and air volume, so that the jet volume and jet flow rate of the rotating jet head 5 can be adjusted through the air intake control system.

[0034] The working method of this application is described below.

[0035] The present application can be provided with a connecting profile 16 on the side plate 7 of the protective cover, and connected to the conveyor line body through the connecting profile 16. The directions of the tray inlet end and the tray outlet end correspond to the conveying direction of the conveyor line body, and the rotating nozzle 5 is connected to the air pump through the regulating valve and the fluid control valve. The tray is transported on the conveyor line body and approaches the tray inlet end. When the tray passes through the tray inlet end, the brush 8 at the tray inlet end performs preliminary dust removal to sweep away larger particles. After that, the tray continues to run under the second cover body 12, and the rotating nozzle 5 rotates and sprays air. The gas passes through the second cover body 12 and blows to the surface of the tray. The gas passing through the surface of the tray carries debris through the gap space 13 and the exhaust pipe 10 and is discharged to the external environment such as the negative pressure dust collection pipeline of the workshop, which can be detected by the wind speed detector 15, and the regulating valve and the fluid control valve are adjusted according to the detection results. When the tray moves to the outside of the tray outlet end, the brush 8 at the tray outlet end performs three dust removals to ensure thorough dust removal.

[0036] The advantage of the present application is that the rotating nozzle 5 is used to blow air non-directionally on the surface of the tray, thereby efficiently washing the surface of the tray. The brush 8 and the ion wind rod 9 are used to perform preliminary dust removal and static removal on the tray, thereby improving the efficiency of subsequent dust removal. By setting the dust removal shield, the first cover body 11 and the second cover body 12, the blown gas passes through the second cover body 12 and is discharged through the first cover body 11, so that the gas flow space is small and the cleaning efficiency is high. At the same time, dust and debris will not be brought between the dust removal shield and the first cover body, preventing other components from being affected.
