Description

Technical Field

[0001] This utility model belongs to the field of glass forming technology, and specifically relates to a glass forming device. Background Technology

[0002] In related technologies, the glass forming process is as follows: after the glass is heated to a softening temperature in a heating furnace, it enters a forming and tempering equipment. The forming and tempering equipment includes a lower pressure roller and an upper pressure roller. The glass is formed under the opposing pressure of the lower pressure roller and the upper pressure roller, and the glass is tempered by blowing air.

[0003] In related technologies, molding and tempering equipment often employs a single drive. For example, the entire transmission system of molding and tempering equipment is driven by a single drive motor. When the molding equipment is in continuous production, the glass needs to be quickly ejected from the furnace and formed in the molding zone, and then slowly moved in the tempering zone for air tempering to ensure that the glass has sufficient tempering time. That is to say, when the glass is in the molding zone, the drive motor provides a relatively high output speed, which is set as Vhigh. When the glass is in the tempering zone, the drive motor provides a relatively low output speed, which is set as Vlow. Vhigh > Vlow. Thus, in the above production process, the output speed of the drive motor has a deceleration process from Vhigh to Vlow.

[0004] Because glass has a certain length, during the process of conveying glass from the forming area to the tempering area, the front end of the glass arrives at the tempering area first, followed by the rear end. If the output speed of the drive motor starts to decelerate from V high when the front end of the glass arrives at the tempering area, the front end of the glass will run at a speed higher than V low for a period of time until the output speed of the drive motor changes to V low. This will result in a relatively long conveying time for the front end of the glass in the high-speed section and a relatively long conveying time for the rear end of the glass in the low-speed section. Consequently, the tempering time for the front end of the glass is short, and the tempering time for the rear end of the glass is long, resulting in a situation where the particle size of the front and rear ends of a piece of glass is inconsistent.

[0053] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0054] Example 1

[0055] See Figures 1 to 7This utility model discloses a glass forming apparatus, comprising: a forming structure 10, which includes a first roller conveyor unit 101; a transition structure 20, which includes a second roller conveyor unit 201 and a first cooling air grid 202; a tempering structure 30, which includes a third roller conveyor unit 301 and a second cooling air grid 302; the forming structure 10, the transition structure 20, and the tempering structure 30 are arranged sequentially along the glass advancing direction; and a driving structure 40, which includes a first driving member 401 and a second driving member 402, wherein the first driving member 401 drives the first roller conveyor unit 101 and the second roller conveyor unit 201 to rotate at a first speed, and the second driving member 402 drives the third roller conveyor unit 301 to rotate at a second speed.

[0056] In this invention, the first driving component 401 drives the first roller conveyor unit 101 and the second roller conveyor unit 201 to rotate at a first speed, and the second driving component 402 drives the third roller conveyor unit 301 to rotate at a second speed. The first speed and the second speed can be the same or different, so this invention can be applied to different application scenarios. When this invention is applied to a continuous production process and the first speed and the second speed are different, the front end and the back end of the glass can run at the second speed within the tempered structure 30 for the same amount of time, thereby improving the situation where the particle size of the front end and the back end of a piece of glass is inconsistent. Furthermore, this invention is provided with a transition structure 20. When this invention is applied to a continuous production process and the first speed and the second speed are different, since the glass is in a relatively soft state when it is in the forming structure 10, the glass can be surface hardened within the transition structure 20 using the first cooling air grid 202, thereby reducing surface scratches caused by speed difference when the glass enters the tempered structure 30 and improving the glass forming quality.

[0057] It should be noted that the direction of glass movement is from the heating furnace 70 towards the glass forming apparatus, that is... Figure 1 In direction A.

[0058] In this embodiment of the invention, the first speed is V1, the second speed is V2, and V1 ≥ V2.

[0059] It should be noted that this glass forming device can perform the following two processing techniques.

[0060] Molding and tempering process one (reciprocating motion production process), see [link / reference]. Figure 1 :

[0061] 11) Both the first driving member 401 and the second driving member 402 rotate clockwise, thereby driving a piece of glass to enter the glass forming device from the heating furnace 70 along direction A.

[0062] 12) All first cooling fan grilles 202 and all second cooling fan grilles 302 are open;

[0063] 13) When the front end of the glass reaches the end of the tempered structure 30, both the first driving member 401 and the second driving member 402 change from rotating clockwise to rotating counterclockwise. The glass moves backward along direction B so that the glass enters the transition structure 20 from the tempered structure 30 until the rear end of the glass reaches the beginning of the transition structure 20.

[0064] 14) When the rear end of the glass reaches the beginning of the transition structure 20, the first driving member 401 and the second driving member 402 both change from rotating counterclockwise to rotating clockwise. The glass moves forward along direction A and enters the tempered structure 30 from the transition structure 20 until the front end of the glass reaches the end of the tempered structure 30.

[0065] Repeat steps 13) and 14) above, so that the glass block moves back and forth between the transition structure 20 and the tempering structure 30. The glass block is tempered by blowing air using the first cooling air grid 202 and the second cooling air grid 302. After the glass block is tempered, the first driving member 401 and the second driving member 402 both rotate clockwise, thereby driving the glass block to be conveyed along the A direction to leave the glass forming device. In the above forming and tempering process one, V1=V2.

[0066] It should be noted that direction B is the opposite of direction A.

[0067] Because the glass increases the tempering time by reciprocating between the transition structure 20 and the tempering structure 30, the forming tempering process does not require "rapid furnace forming followed by slow walking and blowing tempering" to give the glass a sufficiently long tempering time. Therefore, in order to facilitate operation and reduce surface scratches caused by speed difference when the glass enters the tempering structure 30 from the transition structure 20, V1=V2.

[0068] Molding and tempering process two (continuous production process), see below. Figure 1 :

[0069] 21) Both the first driving member 401 and the second driving member 402 rotate clockwise, thereby driving a piece of glass to enter the glass forming device from the heating furnace 70 along direction A.

[0070] 22) All first cooling fan grilles 202 and all second cooling fan grilles 302 are open;

[0071] 23) The glass is formed at the forming structure 10, the glass is surface hardened at the transition structure 20, and the glass is tempered as a whole at the tempering structure 30. After the glass is tempered, the first driving member 401 and the second driving member 402 continue to rotate clockwise, thereby driving the glass to be conveyed along the A direction to leave the glass forming device. In the above forming and tempering process two, V1≥V2.

[0072] It should be noted that in the second molding tempering process, the first driving component 401 and the second driving component 402 always rotate clockwise, and the glass does not undergo the reciprocating motion as in the first molding tempering process. This allows for continuous glass molding tempering with high production efficiency.

[0073] It should be noted that when V1 > V2, the second forming tempering process uses the method of "rapid furnace forming followed by slow walking and blowing tempering" to give the glass a sufficiently long tempering time. This utility model is provided with a transition structure 20. Since the glass is in a relatively soft state when it is forming structure 10, the glass can be surface hardened by the first cooling air grid 202 in the transition structure 20, thereby reducing surface scratches caused by speed difference when the glass enters the tempering structure 30 and improving the glass forming quality.

[0074] The value range of V1 is (1~1.5)V2. The specific values ​​of V1 and V2 are determined according to the actual process requirements and are not limited.

[0075] In this embodiment of the invention, the glass forming apparatus further includes a base 50; the first roller conveyor unit 101 includes a plurality of first upper roller conveyors 1011 and a plurality of first lower roller conveyors 1012, both of which are rotatably connected to the base 50. The first upper roller conveyors 1011 are disposed above the first lower roller conveyors 1012, and the plurality of first upper roller conveyors 1011 are arranged along the glass advancing direction, and the plurality of first lower roller conveyors 1012 are arranged along the glass advancing direction; the second roller conveyor unit 201 includes a plurality of second upper roller conveyors 2011 and a plurality of second lower roller conveyors 2012, the second upper roller conveyors 2011 and the second lower roller conveyors 2012 are... All are rotatably connected to the machine base 50. The second upper roller conveyor 2011 is located above the second lower roller conveyor 2012, and multiple second upper roller conveyors 2011 are arranged along the glass advancing direction, and multiple second lower roller conveyors 2012 are arranged along the glass advancing direction; the third roller conveyor unit 301 includes multiple third upper roller conveyors 3011 and multiple third lower roller conveyors 3012. Both the third upper roller conveyor 3011 and the third lower roller conveyor 3012 are rotatably connected to the machine base 50. The third upper roller conveyor 3011 is located above the third lower roller conveyor 3012, and multiple third upper roller conveyors 3011 are arranged along the glass advancing direction, and multiple third lower roller conveyors 3012 are arranged along the glass advancing direction.

[0076] It should be noted that, for example, Figure 1 as well as Figure 7 Both the first driving component 401 and the second driving component 402 are motors. At this time, the driving structure 40 also includes a first transmission component 403 and a second transmission component 404. The first transmission component 403 is a conveyor belt or a conveyor chain, and the second transmission component 404 is a conveyor belt or a conveyor chain. The first driving component 401 transmits power to multiple first lower roller conveyors 1012 and multiple second lower roller conveyors 2012 through the first transmission component 403. The second driving component 402 transmits power to multiple third lower roller conveyors 3012 through the second transmission component 404.

[0077] It should be noted that the first transmission component 403 can be fitted onto all the first lower roller conveyors 1012 and all the second lower roller conveyors 2012 to achieve power transmission; of course, refer to Figure 7 Alternatively, a first transmission component 403 can be installed between two adjacent first lower roller conveyors 1012, between two adjacent second lower roller conveyors 2012, and between adjacent first lower roller conveyors 1012 and second lower roller conveyors 2012, thereby realizing power transmission; of course, other methods can also be used to realize power transmission, which will not be elaborated here.

[0078] Similarly, the second transmission component 404 can be mounted on all the third lower roller conveyors 3012 to achieve power transmission, or a second transmission component 404 can be mounted between two adjacent third lower roller conveyors 3012 to achieve power transmission; of course, other methods can also be used to achieve power transmission, which will not be elaborated here.

[0079] It should be noted that when the first upper roller 1011 abuts downward against the upper forming surface of the glass and the first lower roller 1012 abuts upward against the lower forming surface of the glass, the glass can be press-formed.

[0080] Since the first upper roller conveyor 1011, the first lower roller conveyor 1012, the second upper roller conveyor 2011, the second lower roller conveyor 2012, the third upper roller conveyor 3011, and the third lower roller conveyor 3012 are all rotatably connected to the machine base 50, when the glass enters between the first upper roller conveyor 1011 and the first lower roller conveyor 1012, the first upper roller conveyor 1011 abuts downward against the upper forming surface of the glass, and the first lower roller conveyor 1012 abuts upward against the lower forming surface of the glass. The first lower roller conveyor 1012 drives the glass to move forward or backward by rotating. Under the action of friction, the glass can also drive the first upper roller conveyor 1011 to rotate. In other words, the glass is both conveyed and pressed in the first roller conveyor unit 101.

[0081] Similarly, when the glass enters between the second upper roller conveyor 2011 and the second lower roller conveyor 2012, the second upper roller conveyor 2011 abuts against the upper forming surface of the glass downwards, and the second lower roller conveyor 2012 abuts against the lower forming surface of the glass upwards. The second lower roller conveyor 2012 drives the glass to move forward or backward by rotating. Under the action of friction, the glass can also drive the second upper roller conveyor 2011 to rotate.

[0082] Similarly, when the glass enters between the third upper roller conveyor 3011 and the third lower roller conveyor 3012, the third upper roller conveyor 3011 abuts downward against the upper forming surface of the glass, and the third lower roller conveyor 3012 abuts upward against the lower forming surface of the glass. The third lower roller conveyor 3012 drives the glass to move forward or backward by rotating. Under the action of friction, the glass can also drive the third upper roller conveyor 3011 to rotate.

[0083] Thus, the first upper roller conveyor 1011 and the second upper roller conveyor 2011 do not need to be equipped with an additional drive structure for power input, and the third upper roller conveyor 3011 also does not need to be equipped with an additional drive structure for power input.

[0084] Of course, after the glass is pressed and formed between the first upper roller 1011 and the first lower roller 1012, the first upper roller 1011 and the first lower roller 1012 can be separated from each other, and the second upper roller 2011 and the second lower roller 2012 can be separated from each other. The glass is placed on the first lower roller 1012 and / or the second lower roller 2012, and the first lower roller 1012 and the second lower roller 2012 can also drive the glass forward or backward. Similarly, the third upper roller 3011 and the third lower roller 3012 can also be separated from each other, and the glass is placed on the third lower roller 3012, and the third lower roller 3012 can also drive the glass forward or backward.

[0085] See Figure 1 as well as Figure 2 In both the first and second forming and tempering processes, the first driving component 401 rotates clockwise, causing the first lower roller conveyor 1012 and the second lower roller conveyor 2012 to rotate clockwise; the first driving component 401 rotates counterclockwise, causing the first lower roller conveyor 1012 and the second lower roller conveyor 2012 to rotate counterclockwise.

[0086] See Figure 1 as well as Figure 2 In both the first and second forming and tempering processes, the second driving component 402 rotates clockwise, causing the third lower roller conveyor 3012 to rotate clockwise; the second driving component 402 rotates counterclockwise, causing the third lower roller conveyor 3012 to rotate counterclockwise.

[0087] See Figure 1 as well as Figure 2The drive structure 40 also includes a tensioning wheel 405, an elastic element 406, a connecting rod 407, and a hinge seat 408. A second transmission element 404 is sleeved on the tensioning wheel 405. The first end of the elastic element 406 is connected and fixed to the base 50. The second end of the elastic element 406 is connected and fixed to the first end of the connecting rod 407. The second end of the connecting rod 407 is provided with a hinge seat 408, which is rotatably connected to the tensioning wheel 405.

[0088] Continue reading Figure 2 Under the elastic force of the elastic element 406, the elastic element 406 drives the tensioning wheel 405 to move in the H direction through the connecting rod 407 and the hinge seat 408, thereby tensioning the second transmission element 404.

[0089] In this embodiment of the invention, a first cooling air grid 202 is provided between two adjacent second upper roller conveyors 2011 along the glass advancing direction, and a first cooling air grid 202 is provided between two adjacent second lower roller conveyors 2012 along the glass advancing direction.

[0090] In this embodiment of the invention, a second cooling air grid 302 is provided between two adjacent third upper roller conveyors 3011 along the glass advancing direction, and a second cooling air grid 302 is provided between two adjacent third lower roller conveyors 3012 along the glass advancing direction.

[0091] In this embodiment of the invention, the distance between two adjacent first upper roller conveyors 1011 along the glass advancing direction is D1, and the distance between two adjacent first lower roller conveyors 1012 along the glass advancing direction is D1; ​​the distance between two adjacent second upper roller conveyors 2011 along the glass advancing direction is D2, and the distance between two adjacent second lower roller conveyors 2012 along the glass advancing direction is D2; the distance between two adjacent third upper roller conveyors 3011 along the glass advancing direction is D3, and the distance between two adjacent third lower roller conveyors 3012 along the glass advancing direction is D3; D1 < D2, and D2 = D3.

[0092] For example, see Figure 7 The roller spacing of the first roller conveyor unit 101 is relatively small, which is conducive to improving the forming accuracy of the glass; the roller spacing of the second roller conveyor unit 201 and the roller spacing of the third roller conveyor unit 301 are relatively large, which is conducive to the flow of cooling air, thus facilitating the tempering of the glass.

[0093] For example, the value range of D1 is 5mm-20mm, and the value range of D2 is 25mm-40mm. The specific values ​​of D1 and D2 are determined according to the actual application scenario and are not limited.

[0094] In this embodiment of the present invention, the first cooling air grid 202 includes at least one first air blowing hole 2021, which faces the position between the second upper roller conveyor 2011 and the second lower roller conveyor 2012; the second cooling air grid 302 includes at least one second air blowing hole 3021, which faces the position between the third upper roller conveyor 3011 and the third lower roller conveyor 3012.

[0095] In this embodiment of the present invention, the first cooling air grid 202 arranged along the glass advancing direction includes a first air blowing hole 2021. The first air blowing hole 2021 of the first cooling air grid 202 arranged along the glass advancing direction faces the position between the second upper roller conveyor 2011 and the second lower roller conveyor 2012, and the first air blowing hole 2021 of the first cooling air grid 202 arranged along the glass advancing direction faces the tempered structure 30.

[0096] For example, see Figures 3 to 4 The first air vent 2021 of the first cooling air vent 202 arranged along the glass advance direction faces the tempered structure 30, thereby preventing the cooling air of the first cooling air vent 202 from blowing towards the forming structure 10 and preventing the cooling air blown out by the first cooling air vent 202 from entering the forming structure 10 and affecting the glass forming.

[0097] See Figure 3 as well as Figure 5 The second first cooling air grille 202, arranged along the direction of glass travel, includes two first air holes 2021 through which cooling gas is blown out.

[0098] See Figure 6 The second cooling air grille 302 includes two second air blowing holes 3021, through which cooling gas is blown out.

[0099] In this embodiment of the present invention, the glass forming apparatus further includes a windbreak structure 60, which includes a first windbreak member 601 and a second windbreak member 602. The first windbreak member 601 is disposed at the upper position between the forming structure 10 and the transition structure 20, and the second windbreak member 602 is disposed at the lower position between the forming structure 10 and the transition structure 20.

[0100] It should be noted that both the first wind deflector 601 and the second wind deflector 602 can be plate parts. The first wind deflector 601 can block the cooling air blown out by the first cooling air grille 202 and the second cooling air grille 302, and the second wind deflector 602 can block the cooling air blown out by the first cooling air grille 202 and the second cooling air grille 302, so as to prevent the cooling air blown out by the first cooling air grille 202 and the second cooling air grille 302 from entering the forming structure 10 and affecting the glass forming.

[0101] See Figure 1 as well as Figure 2 Both the first wind deflector 601 and the second wind deflector 602 are C-shaped, which can return the cooling air blown toward the forming structure 10 to the transition structure 20 and / or the tempered structure 30. This can prevent the cooling air blown out by the first cooling air grille 202 and the second cooling air grille 302 from entering the forming structure 10 and affecting the glass forming, and can also reuse the cooling air blown toward the forming structure 10.

[0102] Example 2

[0105] When the glass is conveyed using the first roller conveyor unit 101, the first upper drive tooth 1013 and the first lower drive tooth 1014 mesh with each other, so that the first lower roller conveyor 1012 is connected to the first upper roller conveyor 1011 through the first lower drive tooth 1014 and the first upper drive tooth 1013. The first upper drive tooth 1013 and the first lower drive tooth 1014 are equal in size, and the first upper roller conveyor 1011 and the first lower roller conveyor 1012 are equal in size, so that the linear velocity of the roller surface of the first upper roller conveyor 1011 is the same as the linear velocity of the roller surface of the first lower roller conveyor 1012.

[0106] It should be noted that the first transmission component 403 is used to realize the transmission connection between two adjacent first lower roller conveyors 1012, and the first lower transmission gear 1014 and the first upper transmission gear 1013 are used to realize the transmission connection between the first lower roller conveyor 1012 and the first upper roller conveyor 1011.

[0107] Similarly, the end of the second upper roller conveyor 2011 is provided with a second upper drive tooth, and the end of the second lower roller conveyor 2012 is provided with a second lower drive tooth.

[0108] When the glass is conveyed using the second roller conveyor unit 201, the second upper drive tooth and the second lower drive tooth mesh with each other, so that the second lower roller conveyor 2012 is connected to the second upper roller conveyor 2011 through the second lower drive tooth and the second upper drive tooth. The second upper drive tooth and the second lower drive tooth are equal in size, and the second upper roller conveyor 2011 and the second lower roller conveyor 2012 are equal in size, so that the linear velocity of the roller surface of the second upper roller conveyor 2011 is the same as the linear velocity of the roller surface of the second lower roller conveyor 2012.

[0109] It should be noted that the first transmission component 403 is used to realize the transmission connection between two adjacent second lower roller conveyors 2012, and the second lower transmission gear and the second upper transmission gear are used to realize the transmission connection between the second upper roller conveyor 2011 and the second lower roller conveyor 2012.

[0110] Similarly, the end of the third upper roller conveyor 3011 is provided with a third upper drive tooth, and the end of the third lower roller conveyor 3012 is provided with a third lower drive tooth.

[0111] When the glass is conveyed using the third roller conveyor unit 301, the third upper drive tooth and the third lower drive tooth mesh with each other, so that the third lower roller conveyor 3012 is connected to the third upper roller conveyor 3011 through the third lower drive tooth and the third upper drive tooth. The third upper drive tooth and the third lower drive tooth are equal in size, and the third upper roller conveyor 3011 and the third lower roller conveyor 3012 are equal in size. Therefore, the linear velocity of the roller surface of the third upper roller conveyor 3011 is the same as the linear velocity of the roller surface of the third lower roller conveyor 3012.

[0112] It should be noted that the second transmission component 404 is used to realize the transmission connection between two adjacent third lower roller conveyors 3012, and the third lower transmission gear and the third upper transmission gear are used to realize the transmission connection between the third upper roller conveyor 3011 and the third lower roller conveyor 3012.
