Description

Technical Field

[0001] The present invention relates to the technical field of ventilation of a coating production line, and in particular to a segmented wind control and energy-saving system. Background Art

[0002] Large spray booths on coating production lines must be equipped with air supply and exhaust devices to continuously supply and exhaust air to the spray booth and ensure the air quality inside the spray booth. Currently, the air supply and exhaust devices in spray booths generally use a full-room air supply system for fresh air ventilation. The so-called full-room air supply means turning on the air supply and exhaust fans of the entire spray booth to supply and exhaust air to the entire booth simultaneously. Although the full-room air supply and exhaust system is simple and the air volume is stable, it is bound to cause a very large waste of energy for large spray booths. This is because in actual painting operations, in many cases, step-by-step segmented spraying operations are mostly carried out. That is, the workpieces in the spray booth are operated in sections according to different painting processes. If full-room air supply and exhaust are used at this time, it is not only unnecessary but also causes serious energy waste. Summary of the Invention

[0034] like Figures 1-12 As shown, a segmented air control energy-saving system is disclosed, which includes a paint spraying room 1, an air supply unit 2 arranged at the upper end of the paint spraying room 1, and an exhaust unit 3 arranged at the lower end of the paint spraying room 1. The air supply unit 2 includes a main air supply pipe 4, and a plurality of branch air supply pipes 5 are arranged at intervals at the lower end of the main air supply pipe 4. A first air valve 15 is provided in each branch air supply pipe 5, and an air outlet cover 6 extending in the left and right directions is provided at the lower end. The lower end of the air outlet cover 6 is an air outlet. The exhaust unit 3 includes a main air supply pipe 4, and a plurality of branch air supply pipes 5 are arranged at intervals at the lower end of the main air supply pipe 4. The exhaust duct 100 and several branch exhaust ducts 101 connected to the main exhaust duct 100, each of the branch exhaust ducts 101 is provided with a second air valve 16, and the number of branch exhaust ducts 101 and branch supply air ducts 5 is arranged correspondingly; the branch exhaust ducts 101 are arranged correspondingly directly below the air outlet hood 6, so that the airflow of each group can be independently controlled by the first air valve 15 and the second air valve 16, and can be opened in sequence according to the stepping position of the workpiece, with a simple structure, a small area occupied by supply and exhaust air, and obvious energy-saving and consumption-reducing effects.

[0035] Furthermore, an air guide assembly is movably provided in the air outlet hood body 6 and directly below the branch air supply pipe 5, and the air guide assembly divides the air outlet hood body 6 into a left air outlet portion 8 and a right air outlet portion 9. The air guide assembly includes an adjustable V-shaped air guide plate 10 and an adjustment device for adjusting the shape of the adjustable V-shaped air guide plate 10. The adjustable V-shaped air guide plate 10 includes a middle hinge seat 11 and a left air guide plate 12 and a right air guide plate 13 hinged to the lower end of the middle hinge seat 11. The adjustment device can adjust the adjustable V-shaped air guide plate 10 to a left-right ventilation form, a left ventilation form, and a right ventilation form.

[0036] In the left and right ventilation mode, the left air guide plate 12 and the right air guide plate 13 guide the air flow into the left air outlet 8 and the right air outlet 9 respectively;

[0037] In the left ventilation mode, the left air guide plate 12 closes the right air outlet 9 and guides the air flow into the left air outlet 8 through the left air guide plate 12;

[0038] In the right ventilation mode, the right air guide plate 13 closes the left air outlet 8 and guides the airflow into the right air outlet 9 through the right air guide plate 13 .

[0039] According to the above structure, the air outlet hood 6 is divided into a left air outlet portion 8 and a right air outlet portion 9 by setting an adjustable V-shaped air guide plate 10, and the shape of the adjustable V-shaped air guide plate 10 can be adjusted by an adjusting device, so that according to the production requirements of spraying, the left air outlet portion 8 and the right air outlet portion 9 can discharge air at the same time or the left air outlet portion 8 can be started alone or the right air outlet portion 9 can be discharged alone, thereby further achieving the effect of saving energy, reducing consumption, saving energy and saving production costs.

[0040] See also Figure 7 、 Figure 9 As shown, a left abutting slope 21 is provided at the connecting corner between the branch air supply pipe 5 and the left air outlet 8, and the middle hinge seat 11 can abut against the left abutting slope 21, so that the adjustable V-shaped air guide plate 10 is in a right ventilation form, and a right abutting slope 22 is provided at the connecting corner between the branch air supply pipe 5 and the right air outlet 9, and the middle hinge seat 11 can abut against the right abutting slope 22, so that the adjustable V-shaped air guide plate 10 is in a left ventilation form.

[0041] See also Figure 4 、 Figure 7 、 Figure 9 As shown, a left sliding seat 31 is hinged at the lower end of the left air guide plate 12, and a right sliding seat 32 is hinged at the lower end of the right air guide plate 13. A left slide groove 33 and a right slide groove 34 extending left and right are provided on the front and rear walls of the air outlet cover 6. The left sliding seat 31 slides in the left slide groove 33, and the right sliding seat 32 slides in the right slide groove 34.

[0042] The shape of the adjustable V-shaped air guide plate 10 is adjusted by sliding the left sliding seat 31 along the left slide groove 33, or sliding the right sliding seat 32 along the right slide groove 34; for example, when the adjustable V-shaped air guide plate 10 requires left and right ventilation shapes, the left sliding seat 31 can slide to the leftmost side of the left slide groove 33, and the right sliding seat 32 can slide to the rightmost side of the right slide groove 34. At this time, the branch air supply pipe 5 is respectively connected to the left air outlet 8 and the right air outlet 9, and at the same time, the openings of the left air guide plate 12 and the right air guide plate 13 are opened wider.

[0043] In addition, the left sliding seat 31 can also slide to the middle position of the left sliding groove 33, and the right sliding seat 32 can slide to the middle position of the right sliding groove 34 (as shown in FIG. Figure 10 As shown), at this time, the branch air supply duct 5 is also connected to the left air outlet 8 and the right air outlet 9 respectively, but the openings of the left air guide plate 12 and the right air guide plate 13 are smaller, that is, the air outlet area of ​​the left air outlet 8 and the right air outlet 9 is increased.

[0044] Of course, the left and right ventilation forms are not limited to the two forms mentioned above. According to the on-site spraying requirements, the position of the left sliding seat 31 in the left slide groove 33 and the position of the right sliding seat 32 in the right slide groove 34 can be adjusted, so that the air outlet area of ​​the left air outlet 8 or the right air outlet 9 can be adjusted.

[0045] When the adjustable V-shaped air guide plate 10 needs to be in the right ventilation mode, the left sliding seat 31 slides to the leftmost position of the left sliding groove 33, and the right sliding seat 32 slides to the leftmost position of the right sliding groove 34 (such as Figure 9 As shown), at this time, the middle hinge seat 11 abuts against the left opposing inclined surface 21, so that the right air guide plate 13 closes the left air outlet 8 and guides the airflow into the right air outlet 9 through the right air guide plate 13.

[0046] See also Figure 3-Figure 11 As shown, the adjusting device includes a motor 41, and a left transmission assembly 42 and a right transmission assembly 43 are respectively connected between the output shaft of the motor 41 and the left sliding seat 31 and the right sliding seat 32. The motor 41 can drive the left transmission assembly 42 alone to work so that the left sliding seat 31 slides back and forth along the left slide groove 33, or the motor 41 can drive the right transmission assembly 43 alone to work so that the right sliding seat 32 slides back and forth along the right slide groove 34.

[0047] Furthermore, a motor mounting seat 51 is provided on the outside of the air outlet cover 6, the motor 41 is provided on the motor mounting seat 51, a gear 52 is provided on the output shaft of the motor 41, and the left transmission assembly 42 and the right transmission assembly 43 have the same structure, wherein both include a disc 53 rotatably provided on the outside of the air outlet cover 6, and a one-way elastic tooth assembly meshing with the gear 52 is uniformly distributed on the circumferential outer wall of the disc 53, and the one-way elastic tooth assembly includes a groove 54 provided on the circumferential outer wall of the disc 53. A first spring 55 and a one-way tooth 56 are provided in the groove 54. The one-way tooth 56 is engaged with the gear 52, and one side of the one-way tooth 56 is a sloped structure 57, and the other side is a straight structure 58. An eccentric column 59 is provided on the outer side of the disc 53. An extension seat 510 extends outward on one side of the left sliding seat 31 and the right sliding seat 32. A vertical plate 511 extends upward on the extension seat 510, and a vertical groove 512 is provided on the vertical plate 511. The eccentric column 59 is provided in the vertical groove 512.

[0048] When the adjustable V-shaped air guide plate 10 switches from the left and right ventilation mode to the right ventilation mode, the working principle is as follows (i.e., from Figure 7 Switch to Figure 9 form):

[0049] The motor 41 drives the gear 52 to rotate counterclockwise. At this time, the teeth of the gear 52 move the straight-face structure 58 of the one-way teeth 56 on the right transmission assembly 43, thereby driving the corresponding disc 53 to rotate. The eccentric column 59 on the disc 53 cooperates with the vertical groove 512 on the vertical plate 511, and then drives the right sliding seat 32 to slide to the left along the right slide groove 34 through the vertical plate 511 and the extension seat 510. When the eccentric column 59 on the disc 53 rotates to the far left, the right sliding seat 32 slides to the far left of the right slide groove 34, and the middle hinged seat 11 abuts against the left opposing inclined surface 21, so that the right air guide plate 13 closes the left air outlet 8, and guides the airflow into the right air outlet 9 through the right air guide plate 13.

[0050] It should be noted that when the gear 52 cooperates with the one-way tooth 56 on the right transmission component 43, the teeth of the gear 52 also cooperate with the one-way tooth 56 on the left transmission component 42, and the teeth of the gear 52 rest against the inclined structure 57 of the one-way tooth 56 on the left transmission component 42, so that the corresponding one-way tooth 56 retracts into the groove 54, the disc 53 on the left transmission component 42 remains stationary, and the left sliding seat 31 does not move.

[0051] Similarly, when the motor 41 drives the gear 52 to rotate clockwise, the right sliding seat 32 will not move, while the left sliding seat 31 can move. Therefore, through the single motor 41 and clever mechanical coordination, the shape of the adjustable V-shaped air guide plate 10 can be quickly adjusted, while further achieving the effect of energy saving and consumption reduction.

[0052] Furthermore, a first elastic positioning component for positioning the disc 53 is also provided on the air outlet cover body 6, and the first elastic positioning component includes a circular groove 61 provided on the outer wall of the air outlet cover body 6, and a second spring 62 and a positioning steel ball 63 are provided in the circular groove 61. A plurality of positioning grooves 64 are evenly distributed along the circumference of the inner wall of the disc 53, and the positioning steel ball 63 is pressed against the positioning groove 64 by the action of the second spring 62, and the positioning groove 64 is corresponding to the one-way elastic tooth component, and the number of the positioning grooves 64 is the same.

[0053] A second elastic positioning component for positioning the left sliding seat 31 and the right sliding seat 32 is also provided on the air outlet cover body 6. The second elastic positioning component includes a wave groove 71 provided on the edge of the lower wall of the air outlet cover body 6. An arc-shaped spring piece 72 is provided on the extension seat 510, and the arc-shaped spring piece 72 rests on the wave groove 71.

[0054] That is to say, the stability of the disc 53 , the left sliding seat 31 and the right sliding seat 32 is improved by disposing the first elastic positioning component and the second elastic positioning component.

[0055] See also Figure 3 As shown, distance sensors 81 are provided at both ends of the air outlet cover 6. The distance sensors 81 are used to measure the distance between the left sliding seat 31 / right sliding seat 32 and the two ends of the air outlet cover 6, so that the positions of the left sliding seat 31 and the right sliding seat 32 can be clearly understood in real time, and the air outlet areas of the air outlet part 8 and the right air outlet part 9 can be clearly understood.

[0056] See also Figure 2 As shown, a filter screen cover 91 is provided at the lower end of the air outlet cover body 6 .
