In some embodiments, the blower module 6 further includes a single fan assembly 62, as shown in fig. 2 and 3; specifically, the single fan assembly 62 is a single fan, and an air outlet of the single fan assembly 62 is an air outlet of the fan. The air collecting cavity is divided into a first air collecting cavity 6111 and a second air collecting cavity 6112, a gate valve 65 is arranged between the first air collecting cavity 6111 and the second air collecting cavity 6112, and the opening and closing of the gate valve 65 controls the communication or the closing of the first air collecting cavity 6111 and the second air collecting cavity 6112; the air inlet pipe is divided into a first air inlet pipe 612 and a second air inlet pipe 613, the first air inlet pipe 612 and the second air inlet pipe 613 are both installed on the rear side surface of the box body 611, the front end of the first air inlet pipe 612 is communicated with the rear end of the first air collecting cavity 6111, the front end of the second air inlet pipe 613 is communicated with the rear end of the second air collecting cavity 6112, the rear end of the first air inlet pipe 612 is connected with the air outlet of the series fan assembly 63, and the rear end of the second air inlet pipe 613 is connected with the air outlet of the single fan assembly 62; the glass heated at high temperature by the heating furnace 2 needs to be cooled after being discharged, the cooling speed of the glass with larger thickness is lower, and the glass is cracked due to the too high cooling speed, so that quality accidents are caused. Therefore, the air pressure of the cooling air needs to be adjusted according to the thickness of the glass, and the quality accident is avoided. As shown in fig. 1, 2, 3 and 14, a first air collecting cavity 6111 and a second air collecting cavity 6112 are provided, the series fan module 63 inputs first cooling air to the first air collecting cavity 6111 through the first air inlet pipe 612, the single fan module 62 inputs second cooling air to the second air collecting cavity 6112 through the second air inlet pipe 613, and because the single fan module 62 has only one fan, and the series fan module 63 has a plurality of independent fans 631 connected in series, the wind pressure of the first cooling air is higher than that of the second cooling air.

The first damper 654 or the second damper 655 can be controlled to move up and down by the first cylinder 652 or the second cylinder 653 respectively, so as to control the opening and closing of the damper valve 65, and further control the connection or the disconnection of the first wind collecting cavity 6111 and the second wind collecting cavity 6112, so as to adjust the wind pressure output by the first group of wind outlet pipes 614 and the second group of wind outlet pipes 614.

A shielding plate assembly 6421 is fixedly connected in the shutter seat 642, the shielding plate assembly 6421 is parallel to the adjusting cover 641, and the sum of the areas of the shielding plate assembly 6421 and the adjusting cover 641 is greater than or equal to the cross-sectional area of the shutter seat 642; for example, the shutter assembly 6421 has a semicircular structure, and the adjustment cover 641 also has a semicircular structure. As another example, the shutter assembly 6421 has a 120 ° fan-shaped structure, and the adjustment cover 641 has a fan-shaped structure larger than 240 °. When the shutter assembly 6421 and the adjusting cover 641 are staggered, the surface formed by the shutter assembly 6421 and the adjusting cover 641 can cover the entire cross-sectional area of the shutter base 642, so as to close the rotary shutter 64. The adjusting cover 641 is provided with a first connection hole 6413, and a central axis of the adjusting cover 641 passes through the first connection hole 6413; the driving mechanism 643 includes a speed reduction motor 6431 and a driving output assembly 6432, the driving output assembly 6432 is fixedly connected to the first connection hole 6413, a rotation shaft of the speed reduction motor 6431 is in transmission connection with the driving output assembly 6432, and the speed reduction motor 6431 drives the adjusting cover 641 to rotate in the shutter seat 642 by taking its own central shaft as a rotation shaft through the driving output assembly 6432; when the adjustment cover 641 and the shutter member 6421 jointly cover the shutter base 642, the rotary shutter 64 is closed, so that the adjustment opening 6321 is closed; when the adjustment cover 641 and the shutter member 6421 are partially or completely overlapped, the rotary shutter 64 is opened, so that the adjustment opening 6321 is opened. Specifically, by adjusting the rotation angle of the adjusting cover 641, the opening of the rotary shutter 64 can be adjusted, so as to adjust the opening of the adjusting opening 6321, thereby achieving the purpose of controlling the wind pressure. When the adjusting cover 641 rotates and the rotary shutter 64 closes, so that the adjusting opening 6321 is closed, the adjusting cover 641 moves towards the direction close to the shielding plate 6421, after the rotary shutter 64 is completely closed, because the adjusting cover 641 moves close to the shielding plate 6421, the gap between the adjusting cover 641 and the shielding plate 6421 is avoided, the airtightness of the rotary shutter 64 is improved, the condition that the wind pressure of the wind collecting box 61 is inaccurate due to wind leakage of the rotary shutter 64 is avoided, and the adjusting accuracy of the wind pressure of the wind supply module 6 is improved, so that the wind flow generated by the wind supply module 6 is kept stable, further the wind flow blown by the cooling wind grid 3 onto the glass surface is kept stable, and the quality of the glass product is improved. In addition, the rotary flashboard 64 adopts a rotary opening and closing structural form, so that the use space is saved compared with a straight flashboard, and the application flexibility of the rotary flashboard 64 is increased.

In some embodiments, as shown in fig. 5 and 6, the driving output assembly 6432 includes a commutator 643A, a screw rod 643B, and a screw rod seat 643C, an input portion of the commutator 643A is connected to a rotating shaft of the reduction motor 6431, an output portion of the commutator 643A is connected to the screw rod 643B, the screw rod 643B is threadedly connected to the screw rod seat 643C, and the screw rod seat 643C is fixed to the shutter seat 642; a central axis of the output part of the commutator 643A, a central axis of the screw holder 643C, and a hole center of the first connection hole 6413 are located on the same straight line, and the screw 643B is fixedly connected with the first connection hole 6413 after passing through the output part of the commutator 643A and the screw holder 643C in sequence; the speed reduction motor 6431 drives the screw rod 643B to rotate through the commutator 643A, and the screw rod 643B rotates and moves telescopically in the screw rod seat 643C and the output part of the commutator 643A along the inner and outer directions of the adjusting opening 6321. While the speed reduction motor 6431 drives the adjusting cover 641 to rotate in the shutter seat 642 by taking the central axis of the speed reduction motor 6432 as a rotating shaft, the screw rod 643B of the driving output assembly 6432 can rotate and make telescopic motion in the inner and outer directions of the adjusting opening 6321, so as to drive the adjusting cover 641 to make telescopic motion in the same direction, and further approach or leave the shutter assembly 6421. Thus, when the adjusting cover 641 rotates to close the rotary shutter 64 and close the adjusting opening 6321, the adjusting cover 641 moves towards the direction approaching the shutter assembly 6421, and finally the adjusting cover 641 completely abuts against the surface of the shutter assembly 6421, so as to avoid a gap between the adjusting cover 641 and the shutter assembly 6421, improve the air tightness of the rotary shutter 64, and prevent the air leakage from the closed adjusting opening 6321; when the adjusting cover 641 rotates to open the rotary shutter 64, so that the adjusting opening 6321 is opened, the adjusting cover 641 moves away from the shutter assembly 6421, thereby preventing friction between the adjusting cover 641 and the shutter assembly 6421, and improving the smoothness of rotation of the adjusting cover 641. Since the central axis of the output portion of the commutator 643A, the central axis of the screw holder 643C, and the hole center of the first connection hole 6413 are located on the same straight line, the straightness of the screw 643B can be ensured, thereby ensuring the smoothness of the screw when rotating.

It should be noted that, as shown in fig. 6, the adjusting cover 641 defines a first opening 6415, the shutter assembly 6421 defines a second opening 642E, and when the rotary shutter 64 is fully opened, the first opening 6415 is aligned with the second opening 642E; the first opening 6415 and the second opening 642E function as wind guiding means, and when the adjusting cover 641 is rotated to align the first opening 6415 with the second opening 642E, the first opening 6415 is communicated with the second opening 642E, so that wind can be discharged to the outside through the rotary shutter 64. The first opening 6415 and the second opening 642E can be shaped differently, such as rectangular, circular, triangular, or scalloped. The first opening 6415 divides the adjustment cover 641 into a first connection portion 6412, a plurality of fan-shaped rotation portions 6411, and a plurality of first arc connection sections 6414, wherein vertex sides of all the fan-shaped rotation portions 6411 are connected by the first connection portion 6412, arc sides of two adjacent fan-shaped rotation portions 6411 are connected by the first arc connection section 6414, the first connection portion 6412 is disposed on a central axis of the damper seat 642, and the first connection hole 6413 is disposed on the first connection portion 6412. As shown in fig. 5 to 11, the driving mechanism 643 drives the first connecting portion 6412 to rotate and drives the first connecting portion 6412 to perform telescopic movement in the inward and outward directions of the adjusting opening 6321, so that the first connecting portion 6412 drives all the sector-shaped rotating portions 6411 to perform the same rotation and the same telescopic movement. Because the fan-shaped rotating part 6411 has a fan-shaped structure, when the fan-shaped rotating part 6411 rotates and performs telescopic motion, one side of an arc of the fan-shaped rotating part 6411 is always matched with the inner wall of the damper seat 642 of the cylindrical tube structure in shape so as not to touch the inner wall of the damper seat 642, thereby ensuring the smoothness of the adjusting cover 641 during rotation. The first arc connecting section 6414 has a function of reinforcing the adjusting cover 641, so that the arc sides of all the fan-shaped shielding portions 642A are connected, thereby improving the firmness and preventing damage when strong wind is applied.

Specifically, as shown in fig. 6, the shielding plate assembly 6421 is provided with a plurality of second openings 642E, the second openings 642E divide the shielding plate assembly 6421 into a second connecting portion 642B, a plurality of fan-shaped shielding portions 642A and a plurality of second arc connecting segments 642D, the arc sides of the fan-shaped shielding portions 642A are fixedly connected to the inner wall of the shutter seat 642, the vertex sides of all the fan-shaped shielding portions 642A are connected to each other through the second connecting portion 642B, the arc sides of two adjacent fan-shaped shielding portions 642A are connected to each other through the second arc connecting segment 642D, and the second arc connecting segment 642D is fixedly connected to the inner wall of the shutter seat 642; the second connecting portion 642B is disposed on a central axis of the shutter base 642, the second connecting portion 642B is provided with a second connecting hole 642C, and the screw rod 643B passes through the second connecting hole 642C and rotates in the second connecting hole 642C. Because the fan-shaped shielding portion 642A has a fan-shaped structure, the arc side of the fan-shaped shielding portion 642A can be matched with the inner wall of the shutter base 642, and the wind shielding effect of the second arc connecting section 642D is combined, so that the air leakage of the adjusting opening 6321 can be avoided after the rotary shutter 64 is closed. In addition, since the apex sides of all the fan-shaped shielding portions 642A are connected by the second connecting portion 642B, the shielding plate assembly 6421 can be stably fixed to the inner wall of the shutter base 642, and is not easily detached from the shutter base 642 even by strong wind. The second connecting portion 642B also serves to support the screw rod 643B, and the screw rod 643B is fixed to the shutter seat 642 through the second connecting portion 642B, so that the connecting shaft of the screw rod 643B rotates relative to the shutter seat 642, and the adjusting cover 641 is driven to rotate. In this embodiment, when the shutter assembly 6421 and the adjustment cover 641 are shifted from each other to close the rotary shutter 64, the combined surface of the fan-shaped rotating portion 6411, the first connecting portion 6412, the fan-shaped shutter portion 642A, and the second connecting portion 642B can cover the entire cross-sectional area of the shutter base 642, thereby achieving the purpose of closing the rotary shutter 64.

As shown in fig. 5, 6, 9 and 10, the sector-shaped rotating portions 6411 are disposed at intervals in the shutter base 642, the sector-shaped shielding portions 642A are disposed at intervals in the shutter base 642, and the number of the sector-shaped rotating portions 6411 is equal to the number of the sector-shaped shielding portions 642A; when the rotary shutter 64 is closed, the fan-shaped rotary portions 6411 and the fan-shaped shade portions 642A are staggered. The inner side of the adjusting opening 6321 of the series air pipe 632 is an air inlet, and the outer side of the adjusting opening 6321 is an air outlet. The greater the number of the sector-shaped rotation portions 6411 and/or the number of the sector shielding portions 642A, the smaller the angle by which the sector-shaped rotation portions 6411 need to rotate when the rotary shutter 64 is opened and closed, and the higher the accuracy of the rotation. The sector-shaped rotating portions 6411 and the sector-shaped shielding portions 642A, which are alternately distributed after the rotary shutter 64 is closed, can be configured to overlap the sector-shaped rotating portions 6411 with the sector-shaped shielding portions 642A when the rotary shutter 64 is opened, so that the first openings 6415 are aligned with the second openings 642E, and wind energy is uniformly discharged from the wind outlet of the turnover shutter. Preferably, the adjusting cover 641 includes two fan-shaped rotation portions 6411, and the two fan-shaped rotation portions 6411 are oppositely disposed at two sides of the first connection portion 6412; the shielding plate assembly 6421 includes two fan-shaped shielding portions 642A, the two fan-shaped shielding portions 642A are disposed at two sides of the second connecting portion 642B, and an angular arc of the fan-shaped shielding portion 642A is 90 °. When the angular arc of the fan-shaped shielding portion 642A is greater than 90 °, the maximum value of the angular arc of a single air inlet is less than 90 °, so that the area of the air inlet is too small to facilitate the flow of strong wind; when the angular arc of the sector shielding portion 642A is smaller than 90 °, the maximum angular arc of a single air inlet is greater than 90 °, the arc length of the air inlet is too long, and the angle at which the adjusting cover plate 641 needs to rotate is too large, which is not favorable for the rapid opening and closing of the rotary shutter 64; when the arc angle of the fan-shaped shielding portion 642A is 90 °, not only strong wind can flow, but also the rotary shutter 64 can be opened and closed quickly.

In some embodiments, as shown in fig. 5 to 11, the adjusting cover 641 is disposed on the air inlet side of the shutter base 642, and the shielding assembly 6421 is disposed on the air outlet side of the shutter base 642. Thus, after the rotary shutter 64 is completely closed, strong wind blows on the surface of the adjustment cover 641 to press the adjustment cover 641 against the shutter assembly 6421, thereby further improving sealing performance and preventing wind leakage. It is noted that the edge of the second opening 642E is provided with a sealing strip 6422. The provision of the seal 6422 further ensures airtightness of the rotary shutter 64, and air is less likely to leak after the rotary shutter 64 is completely closed. Optionally, the damper seat 642 is provided with a protective mesh 6423, the area of the protective mesh 6423 being equal to the cross-sectional area of the damper seat 642. As shown in fig. 4, the protective screen 6423 can effectively isolate large articles from the outside, so as to prevent the large articles from entering the series-connected air pipe 632 and damaging the related equipment of the air supply unit.
