Description

Technical Field

[0001] The invention relates to the technical field of float glass production, and in particular to a tin bath structure used for glass production. Background Art

[0002] In the process of float glass production, the raw materials are mixed and melted, and then the melted glass is poured through a funnel. After being squeezed and stretched, it forms a glass ribbon on the float tin pool. The glass ribbon is spread and flattened on the tin pool to form a glass plate with smooth upper and lower surfaces.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0036] Please refer to 1-7, a tin bath structure for glass production, including a bath body 1, and also including an inclined plate 2, a gear 21 is fixedly arranged on the inclined plate 2, a rack 11 is fixedly arranged on the bath body 1, and the gear 21 is meshed with the rack 11 for transmission; a lifting rod 22 is rotatably arranged on the inclined plate 2, and the lifting rod 22 is slidably connected with the bath body 1, a sliding frame 6 is slidably arranged on the bath body 1, a convex block 61 is fixedly arranged on the sliding frame 6, an inclined groove 24 is arranged on the lifting rod 22, and the convex block 61 is slidably arranged in the inclined groove 24; a first traction roller 3 and a second traction roller 31 are slidably arranged on the bath body 1, a third traction roller 32 is fixedly arranged on the bath body 1, and the first traction roller 3 and the second traction roller 31 are slidably arranged on the bath body 1 A guide column 33 is fixedly provided on each of the two grooves 1, a rotating rod 5 is rotatably provided on the groove body 1, a guide groove 51 is provided on the rotating rod 5, and the two guide columns 33 are slidably provided in the guide groove 51; a substitute component is also included, which is used to compensate for the large distance between the first traction roller 3 and the outlet of the groove body 1, and to adjust the thickness of the molten tin in the groove body 1 when producing glass of different specifications. Subsequently, the sliding frame 6 slides, and during the sliding process of the sliding frame 6, the lifting rod 22 slides with the inclined plate 2 through the cooperation of the protrusion 61 and the inclined groove 24, and under the meshing transmission of the gear 21 and the rack 11, the inclined plate 2 rotates during the sliding process, so that the inclined plate 2 One end of the rotating rod 5 penetrates into the bottom of the molten tin, so as to facilitate the pulling of the glass plate formed above the molten tin. While the inclined plate 2 is adjusted, the rotating rod 5 rotates, and the guide groove 51 on the rotating rod 5 cooperates with the two guide columns 33. The rotation of the rotating rod 5 causes the first pulling roller 3 and the second pulling roller 31 to slide, and in the process of the first pulling roller 3 and the second pulling roller 31 sliding, because the sliding distance is controlled by the rotation of the rotating rod 5, the distance between the first pulling roller 3 and the second pulling roller 31 is equal to the distance between the second pulling roller 31 and the third pulling roller 32, so that when each pulling roller pulls the glass plate, the support of the glass plate is more uniform, which can be more The glass plate can be well supported to improve the stability of the glass plate during the traction process, and the inclination formed between the traction rollers during the sliding process is adapted to the inclination of the inclined plate 2 to avoid bending of the newly formed glass plate when the glass plate is pulled onto the first traction roller 3 through the inclined plate 2, thereby causing the first traction roller 3 to affect the quality of the glass plate during the rotating traction process. When the first traction roller 3 slides to the maximum value, the gap between the first traction roller 3 and the outlet of the trough body 1 is replaced by a substitute component to prevent the first traction roller 3 from being too far away from the outlet of the trough body 1, thereby improving the stability of the newly formed glass plate when it is pulled and improving the forming quality of the glass plate.

[0037] Specifically, a sliding groove 62 is provided on the sliding frame 6, and a sliding block 52 is fixedly provided on the rotating rod 5. The sliding block 52 is slidably set in the sliding groove 62. When the sliding frame 6 slides, when the height and angle of the inclined plate 2 are adjusted, the sliding groove 62 and the sliding block 52 cooperate to rotate the rotating rod 5 to achieve the adjustment of the first traction roller 3 and the second traction roller 31. This not only improves the portability of the inclined plate 2, the first traction roller 3 and the second traction roller 31 when adjusting, but also allows the adjusted inclined plate 2 to be adapted to the first traction roller 3 and the second traction roller 31, thereby improving the traction stability of the glass plate.

[0038] In an embodiment further provided by the present invention, a first spring 23 is arranged between the lifting rod 22 and the trough body 1, and both ends of the first spring 23 are fixedly connected to the lifting rod 22 and the trough body 1 respectively. When the lifting rod 22 descends with the inclined plate 2, the first spring 23 is compressed. When the lifting rod 22 ascends with the inclined plate 2, the first spring 23 is reset, thereby improving the stability of the lifting rod 22 and the inclined plate 2 when they ascend.

[0039] Furthermore, the substitute assembly includes a substitute roller 4 slidably arranged on the trough body 1, and a second spring 41 is arranged between the substitute roller 4 and the trough body 1, and the two ends of the second spring 41 are fixedly connected to the trough body 1 and the substitute roller 4 respectively. When the substitute roller 4 is below the first traction roller 3, the second spring 41 is in a compressed state. When the first traction roller 3 slides to the maximum value, the second spring 41 causes the substitute roller 4 to rise, fills the gap between the first traction roller 3 and the inclined plate 2, supports the glass plate when it is pulled, and improves the stability of the glass plate traction.

[0040] Furthermore, a push-pull rod 7 is slidably provided on the trough body 1, and a pull rope 71 is provided between the push-pull rod 7 and the substitute roller 4, and the two ends of the pull rope 71 are respectively fixedly connected to the push-pull rod 7 and the substitute roller 4. When the push-pull rod 7 slides, the pull rope 71 is loosened, and under the action of the second spring 41, the substitute roller 4 rises to support the glass plate.

[0041] In an embodiment further provided by the present invention, a first clamping block 63 is slidably provided on the sliding frame 6, a first clamping slot 12 is provided on the slot body 1, and the first clamping block 63 is clamped and connected with the first clamping slot 12; a reciprocating block 8 is slidably provided on the slot body 1, a clamping rod 81 is fixedly provided on the reciprocating block 8, a first oblique opening 64 is provided on the first clamping block 63, a first notch 65 is provided on the sliding frame 6, the first oblique opening 64 and the first notch 65 are both slidably matched with the clamping rod 81, a third spring 66 is provided between the first clamping block 63 and the sliding frame 6, and the two ends of the third spring 66 are fixedly connected with the first clamping block 63 and the sliding frame 6 respectively, when the first clamping block 63 and the first clamping slot 12 are not in the clamping state, the first clamping block 63 abuts against the slot body 1, this When the third spring 66 is in a compressed state, the first bevel 64 cooperates with the first notch 65 to fix the clamping rod 81. When the sliding frame 6 slides and adjusts the first traction roller 3 to the maximum value away from the inclined plate 2, the first clamping block 63 coincides with the first clamping groove 12, and under the action of the third spring 66, the first clamping block 63 slides and engages with the first clamping groove 12 to fix the sliding frame 6. In the process of sliding of the first clamping block 63, the first bevel 64 and the first notch 65 are gradually relaxed, so that the clamping rod 81 can continue to slide, so as to drive the push-pull rod 7 to slide, so that the substitute roller 4 rises, and the gap between the first traction roller 3 and the inclined plate 2 is filled, thereby improving the portability of the substitute roller 4 during the substitute process.

[0042] The second engaging groove 74 is provided with the second engaging groove 76, and the second engaging groove 76 is provided with the second engaging groove 76. The second engaging groove 74 is provided with the second engaging groove 76, and the second engaging groove 76 is provided with the second engaging groove 76. The second engaging groove 74 is provided with the second engaging groove 76, and the second engaging groove 76 is provided with the second engaging groove 76. The second engaging groove 74 is provided with the second engaging groove 76, and the second engaging groove 74 is provided with the second engaging groove 76. The second engaging groove 74 is provided with the second engaging groove 76, and the second engaging groove 74 is provided with the second engaging groove 76. The sliding of the push-pull rod 7 can also drive the push-pull rod 7 to slide and reset. When the push-pull rod 7 slides, the pull rope 71 is loosened to make the substitute roller 4 move up and fill the gap between the first traction roller 3 and the inclined plate 2. When the clamping rod 81 slides in the opposite direction, the substitute roller 4 can be lowered and reset by driving the push-pull rod 7. After the reset is completed, under the action of the fourth spring 75, the second clamping block 72 is engaged with the second clamping groove 13 to complete the fixation of the substitute roller 4. Then the clamping rod 81 continues to slide in the opposite direction, and the first clamping block 63 can be slid out of the first clamping groove 12 through the first oblique opening 64. When the first clamping block 63 slides, the first notch 65 and the first oblique opening 64 clamping rod 81 are fixed, so that the clamping rod 81 drives the sliding frame 6 to reset, which greatly improves the portability when adjusting the first traction roller 3, the second traction roller 31, the inclined plate 2 and the substitute roller 4.

[0043] Specifically, a screw rod 9 is rotatably provided on the trough body 1, and the screw rod 9 is threadedly connected to the reciprocating block 8. A motor 91 is fixedly provided on the trough body 1, and the output shaft of the motor 91 is fixedly connected to the screw rod 9. The screw rod 9 is driven to rotate by the motor 91, so that the reciprocating block 8 slides with the clamping rod 81, thereby completing the adjustment and fixation of the first traction roller 3, the second traction roller 31, the inclined plate 2 and the substitute roller 4.

[0044] In the present invention, the first traction roller 3, the second traction roller 31, the third traction roller 32, and the substitute roller 4 mentioned all include a roller body and a lower support member, the roller body and the lower support member are rotatably connected, and the sliding adjustment mentioned is that the roller body and the lower support member slide simultaneously, which will not be elaborated in detail; and the third traction roller 32 is fixed, and it cooperates with the conveying device used for the subsequent annealing of the glass plate to transport the glass plate.

[0045] Working principle: when adjusting the inclination angle of the inclined plate 2, the motor 91 drives the screw rod 9 to rotate, and the reciprocating block 8 slides with the clamping rod 81. At this time, because the first clamping block 63 abuts against the bottom of the slot body 1, the first notch 65 cooperates with the first oblique slot 64 to fix the clamping rod 81. The clamping rod 81 drives the sliding frame 6 to slide when sliding. During the sliding process of the sliding frame 6, the lifting rod 22 brings the inclined plate 2 down through the cooperation of the protrusion 61 and the oblique slot 24. Under the action of the rack 11, the gear 21 rotates with the inclined plate 2 as the inclined plate 2 descends, thereby completing The tilt angle and height of the tilted plates 2 are adjusted in pairs. At the same time, when the sliding frame 6 slides, the sliding groove 62 cooperates with the sliding block 52 to rotate the rotating rod 5, and the guide groove 51 cooperates with the guide column 33 to make the rotating rod 5 push the first traction roller 3 and the second traction roller 31 to slide when rotating. The distance between the traction rollers is adjusted to adapt to the tilt angle of the tilted plate 2, so that the glass plate will not bend when it is pulled from the tilted plate 2 to the first traction roller 3, thereby improving the stability of the glass plate when it is sent out from the trough body 1;

[0046] After the first traction roller 3 and the second traction roller 31 slide to the maximum value, the sliding frame 6 slides with the first clamping block 63 to the position of the first clamping groove 12. At this time, the reciprocating block 8 continues to slide with the clamping rod 81. Under the abutment of the clamping rod 81 and the first bevel 64 and the action of the third spring 66, the first clamping block 63 is engaged with the first clamping groove 12, and the clamping rod 81 is disengaged from the sliding frame 6. Then the clamping rod 81 slides and under the action of the second bevel 73, the second clamping block 72 is disengaged from the second clamping groove 13, and the fourth spring 75 is compressed. At this time, the second bevel 73 and the second notch 74 fix the clamping rod 81. Then, the clamping rod 81 drives the push-pull rod 7 to slide, loosens the pull rope 71, and under the action of the second spring 41, the substitute roller 4 rises to substitute the gap between the first traction roller 3 and the inclined plate 2, thereby improving the supporting effect when the glass plate is pulled.

[0047] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
