Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of glass manufacturing equipment, in particular to a wind grid limiting mechanism with swing-type retraction and release. Background Art
[0002] When thin glass is tempered and rapidly cooled, the air outlet velocity and air pressure of the air nozzles of the high-pressure section wind grid are very large, which will cause the upper wind grid to be sharply pushed up and lifted, thus changing the blowing distance from the air nozzles to the glass and directly affecting the tempering effect. The prior art is to install one or more groups of cylinders on the frame, or add counterweights on the upper wind grid. The disadvantages of this solution are as follows: First, the blowing and the opening of the cylinders cannot be completely synchronized, resulting in the situation that before the blowing starts, the cylinders have already pressed on the wind grid with full force, causing an additional large pulling force on the lifting chain of the wind grid and accelerating the wear and failure of the lifting system; Second, the magnitude and acting point of the air pressure counter-thrust force cannot be accurately measured, so it is difficult to accurately match the cylinder thrust with it, affecting the tempering effect; Third, when multiple cylinders are used together, the space is cramped, and the procurement and processing of parts are very uneconomical. Content of the Utility Model
[0003] The purpose of the utility model is to solve the problems in the prior art that the use of multiple groups of cylinders or counterweights to pressurize the upper wind grid has poor economy and will also affect the tempering effect, and to propose a wind grid limiting mechanism with swing-type retraction and release.
[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0005] A wind grid limiting mechanism with swing-type retraction and release includes a mounting seat, a driving unit, and a swing pressing plate installed on one side of the upper wind grid. The driving unit is installed on the frame through the mounting seat, the swing pressing plate is connected to the working end of the driving unit, and the driving unit drives the swing pressing plate to swing, away from or close to the top of the upper wind grid.
[0006] Further, the driving unit is a rotary driving structure.
[0007] Further, the driving unit is a rotary cylinder.
[0008] Further, the mounting seat includes a vertical plate, a vertical board, and a horizontal board. One end face of the vertical plate is connected to the frame, and the other end is connected to the vertical board and the horizontal board. The vertical board is located between the vertical plate and the horizontal board, and the driving unit is installed on the horizontal board.
[0009] Further, there are two vertical boards and two horizontal boards. The two horizontal boards are parallel and spaced apart, and the two vertical boards are respectively located on the end faces of the two horizontal boards away from each other;
[0010] A swing pressing plate is arranged between the two horizontal boards. The swing pressing plate is connected to the working end of the driving unit, and the swing pressing plate is rotatably connected to the horizontal board.
[0011] Further, auxiliary plates are respectively arranged on the end faces of the two cross plates close to each other, and the swing pressing plate is rotatably installed between the two auxiliary plates.
[0012] Further, the swing pressing plate includes a slider and a pressing block. The slider is connected to the working end of the driving unit. One end of the slider is connected to the pressing block. The driving unit drives the pressing block to rotate through the slider, so that the pressing block approaches or moves away from the upper air grille.
[0013] Further, a buffer block is arranged on the bottom surface of the pressing block.
[0014] Further, the bottom surface of the buffer block is an inclined surface, and the side of the inclined surface close to the upper air grille is higher than the side away from the upper air grille.
[0015] Compared with the prior art, the present utility model provides a wind grille limiting mechanism with swing type retraction and extension, and has the following beneficial effects:
[0016] For the wind grille limiting mechanism with swing type retraction and extension of the present utility model, during use, this mechanism is installed on the frame on one side of the upper air grille through the mounting seat, so that this mechanism is located above the side of the upper air grille. When it is necessary to use the high-pressure air blown out by the upper air grille, the driving unit is started to drive the swing pressing plate to approach and press on the top of the upper air grille. When the upper air grille is started to blow high-pressure air to rapidly cool the thin glass, the upper air grille cannot be lifted under the limiting action of the swing pressing plate, thereby ensuring the rapid cooling effect of the upper air grille on the thin glass. Compared with the prior art in which multiple cylinders and counterweight blocks are used for pressurization, the structure is simpler, and when the upper air grille is not working, the swing pressing plate is retracted to avoid increasing the load of the lifting chain of the upper air grille.

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0026] Referring to Figures 1-5 , a wind grille limiting mechanism with swing type retraction and extension of the present utility model includes a mounting seat 1, a driving unit 2, and a swing pressing plate 3 installed on one side of the upper air grille 4. The driving unit 2 is installed on the frame 5 through the mounting seat 1, and the upper air grille 4 is also installed on the frame 5. The swing pressing plate 3 is connected to the working end of the driving unit 2, and the driving unit 2 drives the swing pressing plate 3 to swing, away from or close to the top of the upper air grille 4.
[0027] During use, the driving unit 2 drives the swing pressing plate 3 to approach the top of the upper air grille 4 and press on it to limit the upper air grille 4, or the driving unit 2 drives the swing pressing plate 3 to reset, so as to be away from the top of the upper air grille 4 and disengage from the upper air grille 4 to release the constraint on the upper air grille 4.
[0028] The driving unit 2 is a rotary driving structure, which can be a motor, a rotary cylinder, or other driving sources that can realize rotary output of the working end, so as to drive the swing pressing plate 3 to rotate. The positive direction is to rotate towards the top of the upper air grille 4, and the reverse direction is to rotate away from the top of the upper air grille 4.
[0029] In this application, the driving unit 2 is selected as a rotary cylinder. Compared with a motor, it can be directly connected to the swing pressing plate 3 without an intermediate transmission mechanism to drive the swing pressing plate 3 to rotate. The driving unit 2 in this application is set to have a rotation angle of 90 degrees, driving the swing pressing plate 3 towards the upper air grille 4 in the positive direction, or driving the swing pressing plate 3 away from the upper air grille 4 (reset) in the reverse direction.
[0030] The mounting base 1 includes a vertical plate 101, a vertical plate 102, and a horizontal plate 103. One end face of the vertical plate 101 is connected to the frame 5, and the other end is connected to the vertical plate 102 and the horizontal plate 103. The vertical plate 102 is located between the vertical plate 101 and the horizontal plate 103. The vertical plate 102 has a right triangle structure, and the two right sides of the vertical plate 102 are respectively fixedly connected to the vertical plate 101 and the horizontal plate 103 to strengthen the stability of the horizontal plate 103. The driving unit 2 is installed on the horizontal plate 103, specifically as Figures 1-2 shown.
[0031] There are two vertical plates 102 and two horizontal plates 103. The two horizontal plates 103 are parallel and spaced apart, and the two vertical plates 102 are respectively located on the end faces of the two horizontal plates 103 away from each other to ensure the stability of the horizontal plates 103;
[0032] A swing pressure plate 3 is installed between the two horizontal plates 103. The swing pressure plate 3 is connected to the working end of the driving unit 2, and the swing pressure plate 3 is rotatably connected to the horizontal plate 103. Specifically, a transmission shaft is keyed to the working end of the rotary cylinder. The transmission shaft passes through the two horizontal plates 103, and the transmission shaft is rotatably connected to the horizontal plate 103. Then the swing pressure plate 3 is keyed to the transmission shaft, so that the driving unit 2 drives the swing pressure plate 3 to rotate and swing through the transmission shaft.
[0033] Auxiliary plates 104 are respectively installed on the end faces of the two horizontal plates 103 close to each other. The swing pressure plate 3 is rotatably installed between the two auxiliary plates 104. Among them, the auxiliary plates 104 are made of high-hardness and high-wear-resistant steel to reduce wear, while the horizontal plates 103 are made of high-toughness and high-rigidity steel to ensure the structural strength.
[0034] The swing pressure plate 3 includes a slider 301 and a pressure block 302. The slider 301 is connected to the working end of the driving unit 2. The slider 301 is located between the two auxiliary plates 104. The slider 301 is keyed to the transmission shaft. Lubricant is applied between the slider 301 and the auxiliary plates 104. One end of the slider 301 is connected to the pressure block 302. The driving unit 2 drives the pressure block 302 to rotate through the slider 301, so that the pressure block 302 approaches or moves away from the upper air grille 4. Specifically, the pressure block 302 swings reciprocally with the transmission shaft as the center of the circle, approaches and presses on the top of the upper air grille 4, or moves away and disengages from the top of the upper air grille 4.
[0035] A buffer block 303 is installed on the bottom surface of the pressure block 302. The buffer block 303 is glued or fixed to the bottom of the pressure block 302 using fasteners. The buffer block 303 can be made of plastic, such as engineering plastic, polyurethane, etc., to play a buffering role, avoid rigid collision between the pressure block 302 and the top of the upper air grille 4, and improve the operating stability of this mechanism.
[0036] The bottom surface of the buffer block 303 is an inclined plane. The side of the inclined plane close to the upper air grille 4 is higher than the side far from the upper air grille 4. Specifically, if the buffer block 303 is taken as an example of a cuboid-like structure, as Figures 3-4 , Figures 3-4 The shape of the buffer block 303 in Figure 1 corresponds to the state in Figure 2 . The buffer block 303 is in a state after being rotated 90 degrees. The top surface of the buffer block 303 is a plane. The length of the first vertical rib 304 is less than the lengths of the second vertical rib 305 and the third vertical rib 306. The lengths of the second vertical rib 305 and the third vertical rib 306 are less than the length of the fourth vertical rib 307 (the first vertical rib 304 and the third vertical rib 306 in the figure are two vertical ribs with the same length and parallel after chamfers are set). In this way, when the buffer block 303 rotates with the pressing block 302 from the state in Figure 1 to the state in
[0037] This solution converts the frequency and uncertainty of using a cylinder to apply pressure into directly using the rack extension structure to limit the upward movement freedom of the upper air grille 4, and only one small cylinder is used to realize the retraction and extension of the pressing plate.
[0038] Working principle: The rotary cylinder is fixed to the rack 5. When no limit is required, the rotary cylinder returns to the zero position, and the swing pressing plate 3 retracts to the front end face far from the upper air grille 4. When it is necessary to limit the upper air grille 4, the rotary cylinder swings 90°, and the swing pressing plate 3 expands to be perpendicular to the front end face of the air grille. The bottom surface of the buffer plate block 03 presses on the upper surface of the upper part in front of the upper air grille 4. At this time, it is only an elastic contact and no force is applied. When the upper air grille 4 is pushed upward by the wind pressure, the swing pressing plate 3 will passively limit the upper air grille 4 so that it cannot be lifted.
