Example

[0029] like Figure 1-6As shown, the energy-saving single-blower glass washing machine includes a roller conveyor line 1, and an upper section 2, a cleaning section 3, an air-drying section 4 and a lower section 5 which are longitudinally distributed in sequence on the roller conveyor line 1. Glass is placed on the roller conveyor line 1 and passes through the upper section 2, the cleaning section 3, the air-drying section 4 and the lower section 5 in sequence. The glass is loaded on the upper section 2, washed with water in the cleaning section 3, dried by blowing in the air-drying section 4, and transferred to the lower section 5 for unloading.

[0030] In this embodiment, a blowing device is provided on the air-drying area 4, and the blowing device includes a fan 41, an air supply channel 42, an air outlet pipe 43 and a shift assembly 44, wherein the fan 41 is a variable frequency fan, which can be automatically frequency-adjusted by PLC; of course, it can also be an ordinary fan, which can be manually frequency-adjusted.

[0031] The air outlet duct 43 is arranged between the rollers of the roller conveyor line 1. The air supply channel 42 is a box-type structure, which is arranged horizontally. A channel air inlet 421 is provided on its side wall, which is connected to the air outlet of the fan 41. A plurality of air supply areas are arranged in the air supply channel 42. A plurality of air outlet sections are correspondingly arranged on the air outlet duct 43. The air supply areas and the air outlet sections are connected one by one through connecting pipes. The shift assembly 44 is arranged behind the channel air inlet 421 to guide the air to a certain air supply area or multiple air supply areas, and finally the air is discharged from a certain air outlet section or multiple air outlet sections.

[0032] The air drying area 4 further includes an air drying hood 45 , in which a fan 41 and an air supply channel 42 are installed. The air drying hood 45 is mounted above the air outlet pipe 43 .

[0033] Specifically, Figure 2-5 As shown, the shift assembly 44 includes a push-pull cylinder 441, a connecting rod 442, a rotating shaft 443 and a wind shield 444. The rotating shaft 443 is rotatably arranged on the air supply channel 42. The piston rod end of the push-pull cylinder 441 is hinged to one end of the connecting rod 442, and the other end of the connecting rod 442 is fixed to the rotating shaft 443. The wind shield 444 is located in the air supply channel 42 and fixed on the rotating shaft 443. The wind shield 444 is located behind the air inlet 421 of the channel; the rotating shaft 443 is driven to rotate by the extension and retraction of the piston rod of the push-pull cylinder 441, and then the wind shield 444 is driven to swing, thereby guiding the direction of wind flow. More specifically, the rotating shaft 443 is arranged on the side of the box wall opposite to the channel air inlet 421 of the air supply channel 42, the rotating shaft 443 is penetrated on the air supply channel 42, the upper part of the rotating shaft 443 protrudes from the upper wall of the air supply channel 42, the connecting rod 442 and the push-pull cylinder 441 are located above the air supply channel 42, the windshield 444 is located in the air supply channel 42, and the height of the windshield 444 corresponds to the height of the air supply channel 42. By externally placing the push-pull cylinder 441, the activity space of the windshield is larger, and the installation and maintenance are more convenient. Of course, the push-pull cylinder 441 can also be installed in the air supply channel 42, and the push-pull cylinder 441 is connected to the windshield through a connecting piece to drive it to swing.

[0034] The rear end of the push-pull cylinder 441 is connected to a hinge seat 445, and the shift assembly 44 further includes a fixed mounting plate 446, which is L-shaped, and the horizontal plate surface of the fixed mounting plate 446 is fixed to the outer wall of the air supply channel 42, and the hinge seat 445 is fixed to the vertical plate surface of the fixed mounting plate 446. Both ends of the push-pull cylinder 441 are hinged, so that when the piston rod of the push-pull cylinder 441 is extended and retracted, the push-pull cylinder 441 can swing flexibly, and the swing range of the windshield 444 driven by the connecting rod 442 can be expanded.

[0035] In this embodiment, Figure 4 , 5 As shown, the inner cavity of the air supply channel 42 is divided into two left and right air supply areas, namely a left air supply area 422 and a right air supply area 423. The left air supply area 422 and the right air supply area 423 are connected. A left air supply pipe opening 424 is set at the left end of the left air supply area 422, and a right air supply pipe opening 425 is set at the right end of the right air supply area 423. Figure 6 As shown, the air outlet pipe 43 is in the shape of a long tube, and the air outlet pipe 43 is divided into a left air outlet section 431 and a right air outlet section 432 which are not connected by a partition plate 434. Figure 1 As shown, a left air outlet 4311 is provided at the left end of the left air outlet section 431, and a right air outlet 4311 is provided at the right end of the right air outlet section 432. The left air outlet 4311 is connected to the left air supply 424 through a connecting pipe (not shown in the figure), and the right air outlet is connected to the right air supply 425 through a connecting pipe (not shown in the figure); an air outlet gap 433 is also provided at the bottom of the air outlet 43, and the opening of the air outlet gap 433 faces the glass. The air outlet 43 can be a straight air knife or an oblique air knife.

[0036] The glass cleaning machine includes three groups of air outlet pipes arranged at intervals in the front and back, each group of air outlet pipes includes two air outlet pipes 43 with upper and lower air outlet gaps 433 facing each other, and the glass is transported from between the two air outlet pipes 43 of each group of air outlet pipes; the left air supply pipe openings 424 of the left air supply area 422 on the corresponding air supply channel 42 are set to 6, and the right air supply pipe openings 425 of the right air supply area 423 are set to 6, the left air outlet pipe opening 4311 of each air outlet pipe 43 is connected to a left air supply pipe opening 424, and the right air outlet pipe opening of each air outlet pipe 43 is connected to a right air supply pipe opening 425.

[0037] like Figure 4 , 5 As shown, a left connecting plate 447 and a right connecting plate 448 are respectively provided on the left and right sides of the rear of the channel air inlet 421, and the wind shield plate 444 can be abutted against the left connecting plate 447 or the right connecting plate 448, and the wind shield plate 444 swings between the left connecting plate 447 and the right connecting plate 448; a fixed baffle 449 is also provided between the rotating shaft 443 and the box wall of the air supply channel 42 behind it.

[0038] The fixed baffle 449 is used to separate the area behind the rotating shaft 443 from the left and right, further ensuring the independence of the left air supply area 422 and the right air supply area 423. At the same time, the rotating shaft 443 does not need to be set against the wall, and the rotation will be more flexible. The setting of the left connecting plate 447 and the right connecting plate 448 can limit the rotation range of the wind shield 444, and at the same time reduce the front and rear length of the board surface of the wind shield 444 to avoid scratching during the rotation process. The left connecting plate 447, the right connecting plate 448 and the wind shield 444 can cooperate to more effectively isolate the left and right areas of the air supply channel, so that the wind can be discharged to the left or right when necessary.

[0039] In this embodiment, three-speed air outlet can be achieved. When the wind shield 444 is in contact with the left connecting plate 447, the channel air inlet 421 is only connected to the right air supply area 423, and the wind shield 444, the left connecting plate 447, and the fixed baffle 447 work together to block the wind from the left air supply area 422, so that the wind only flows out from the right air supply area 423, that is, from the right air outlet section 432; when the wind shield 444 is in contact with the right connecting plate 448, the channel air inlet 421 is only connected to the left air supply area 422, and the wind shield 444, the right connecting plate 448, and the fixed baffle 447 work together to block the wind from the right air supply area 423, so that the wind only flows out from the left air supply area 422, that is, from the left air outlet section 431; thus, the single-side air outlet of the air outlet duct 43 is achieved. When the wind shield plate 444 is located between the left connecting plate 4211 and the right connecting plate 4212 , the channel air inlet 421 is connected to the left air supply area 422 and the right air supply area 423 at the same time, and the entire air outlet duct 43 discharges air.

[0040] In this embodiment, the push-pull cylinder 441 is arranged on the left side of the channel air inlet 421, the piston rod is extended forward to a fully extended state, the wind shield plate 444 moves toward the right connecting plate 448 until it is in abutment with the right connecting plate 448, and air is discharged from the left side of the air outlet duct 43; the piston rod is retracted to a fully retracted state, the wind shield plate 444 moves toward the left connecting plate 447 until it is in abutment with the left connecting plate 447, and air is discharged from the right side of the air outlet duct 43; the piston rod is extended forward to a half-extended state, the wind shield plate 444 is located between the left connecting plate 4211 and the right connecting plate 4212, and air is discharged from the entire air outlet duct 43.

[0041] In this embodiment, the ratio of the horizontal lengths of the left air outlet section 431 and the right air outlet section 432 of the air outlet pipe 43 is 1:1.

[0042] When the glass width is less than 1 / 2 length of the roller, the piston rod of the push-pull cylinder 441 is set in a fully retracted state, the glass is transported from the right side of the roller, and the air outlet pipe 43 discharges air from the right side, that is, the right air outlet section 432 discharges air to dry the glass; when the glass width is greater than 1 / 2 length of the roller, the piston rod of the push-pull cylinder 441 is set in a semi-extended state, the glass is transported from the middle of the roller, and the entire air outlet pipe 43 discharges air, that is, the left air outlet section 431 and the right air outlet section 432 discharge air at the same time to dry the glass.

[0043] When the air outlet duct is partially discharging air, the air outlet diameter becomes smaller and the air pressure becomes larger. The fan can be frequency-converted as needed to make the air outlet duct discharge air at a constant pressure or at a variable pressure.

[0044] The specific test data can be seen in the following table:

[0045]

[0046] It can be seen from the test data in the above table that when the air outlet is fully open, the fan input frequency is 200Hz, its input current is 22.3A, and the air pressure of the air outlet is 53Pa. When the air outlet is controlled to be half open, if the input frequency of the same fan is maintained at 200Hz, its input current will be reduced to 19A, and the energy consumption will be reduced. At the same time, the air pressure of the air outlet will rise to 65Pa. The glass will receive a greater wind pressure under the same input frequency, and the glass will be blown cleaner; if the wind pressure is maintained at 53Pa, the input frequency will be reduced to 183Hz, and the input current will be reduced to 13A, which significantly reduces energy consumption. The program can be set through the PLC to maintain the input frequency or maintain the wind pressure. In either case, the energy consumption is significantly reduced, which has an energy-saving effect. Example

[0047] Compared with the first embodiment, the ratio of the horizontal lengths of the left air outlet section 431 and the right air outlet section 432 of the air outlet pipe 43 is 2:1.

[0048] When the glass width is less than 1 / 3 of the length of the roller, the piston rod of the push-pull cylinder 441 is set in a fully retracted state, the glass is transported from the right side of the roller, and the air outlet pipe 43 discharges air from the right side, that is, the right air outlet section 432 discharges air to dry the glass; when the glass width is greater than 1 / 3 of the length of the roller but less than 2 / 3 of the length of the roller, the piston rod of the push-pull cylinder 441 is set in a fully extended state, the glass is transported from the left side of the roller, and the air outlet pipe 43 discharges air from the left side, that is, the left air outlet section 431 discharges air to dry the glass; when the glass width is greater than 2 / 3 of the length of the roller, the piston rod of the push-pull cylinder 441 is set in a semi-extended state, the glass is transported from the middle of the roller, and the entire air outlet pipe 43 discharges air, that is, the left air outlet section 431 and the right air outlet section 432 discharge air at the same time to dry the glass. Example

[0049] Compared with the first embodiment, the inner cavity of the air supply channel 42 can be divided into three or more areas, and the corresponding air outlet pipe is divided into three or more sections. Two or more groups of shifting components 44 are arranged on the air supply channel 42 to introduce air into one or more air supply areas, and finally the air outlet pipe 43 is partially or completely discharged, so as to achieve the zoning control air outlet effect of the glass cleaning machine. The horizontal length ratio of each air outlet section of the corresponding air outlet pipe can be adjusted as needed. Example

[0050] like Figure 7As shown, compared with the first embodiment, in this embodiment, a shift assembly 44 is respectively provided at the air outlet ends on both sides of the air supply channel 42, and the inner cavity of the air supply channel 42 is actually still equivalent to being divided into a left air supply area and a right air supply area, and the wind still flows out from the left air supply pipe opening 424 and / or the right air supply pipe opening 425. At this time, the shift assembly 44 acts as a gate switch. When the wind needs to flow out from the left air supply pipe opening 424, the shift assembly 44 on the left side of the air supply channel 42 is opened to allow the air to flow out, otherwise it is closed; similarly, when the wind needs to flow out from the right air supply pipe opening 425, the shift assembly 44 on the right side of the air supply channel 42 is opened. This is a deformed structure of the shift effect of the shift assembly 44 in the first embodiment. Example

[0051] like Figure 8 As shown, compared with the fourth embodiment, in this embodiment, the shift assembly 44 is arranged at the left air supply pipe opening 424 and the right air supply pipe opening 425, which can also play the effect of controlling the actual air outlet direction of the air supply channel 42, and one shift assembly 44 can open or close one or more air supply pipe openings. The structure of the shift assembly 44 here will also be deformed accordingly according to the shape of the left air supply pipe opening 424 and the right air supply pipe opening 425, so as to block / open the pipe openings. Example

[0052] Compared with the first embodiment, as a variation of the single fan of the utility model, multiple fans are provided to supply air to a single air supply duct at the same time, which is equivalent to the air supply function of the single fan of the utility model. Example

[0053] Compared with the first embodiment, the blowing device can be arranged as multiple sets in parallel, that is, multiple air outlet pipes can correspond to the air supply of multiple fans.

[0054] The above is only a preferred embodiment of the present application and does not constitute any formal limitation to the present application. Any technician familiar with the art can make many possible changes and modifications to the technical solution of the present application by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the present application, or modify it into an equivalent embodiment of equivalent changes.
