Description

Technical Field

[0001] This invention relates to the field of glass forming equipment technology, and in particular to a glass forming device and a glass forming furnace that facilitates the disassembly and assembly of clamping rollers. Background Technology

[0002] Currently, domestic LCD glass substrates are mainly produced using the overflow and pull-down methods, with multi-roller clamping technology being a crucial technique for controlling the quality of glass manufacturing. During normal production, the refractory protrusions of the clamping rollers need to extend into the furnace and maintain constant contact with the glass. To stabilize the furnace temperature, the furnace opening requires a certain degree of sealing. However, while ensuring a tight seal, it's also essential to ensure that the sealing window assembly can be quickly opened and withdrawn when the clamping rollers need to be replaced, without affecting the normal lateral movement of the clamping rollers. Existing glass forming furnaces struggle to simultaneously guarantee a tight seal while ensuring rapid opening and withdrawal and the flexible movement of the clamping rollers. Summary of the Invention

[0003] To address the technical problems existing in the background art, the present invention proposes a glass forming device and a glass forming furnace that facilitates the assembly and disassembly of clamping rollers.

[0004] The present invention proposes a glass forming furnace with convenient clamping roller disassembly and assembly, comprising: a furnace body, a first sealing window provided on the first side wall of the furnace body and a window sealing mechanism for covering and sealing the first sealing window;

[0005] The window sealing mechanism includes two clamps and a sealing baffle. The two clamps are fixed to the first sidewalls on the left and right sides of the first sealing window, respectively. The sealing baffle has two second sealing windows arranged along the second horizontal direction in the middle. Each second sealing window has a sliding plate that slides along the second horizontal direction. The sliding plate has a through hole for the clamping roller to pass through. The left and right sides of the sealing baffle are respectively provided with clamp receiving platforms for clamping the clamps. The clamps are pressed against the clamp receiving platforms to seal and cover the first sealing window.

[0006] Preferably, the sealing baffle is provided with a plurality of first waist-shaped holes spaced apart along the circumference, and a first waist-shaped block matching the first waist-shaped hole is provided on the first side wall at the position corresponding to the first waist-shaped hole. The first waist-shaped block is used to be inserted into the corresponding first waist-shaped hole when the sealing baffle seals and covers the first sealing window.

[0007] Preferably, the sealing baffle has a limiting groove extending in the second horizontal direction on the side facing the first sidewall. The left and right sides of the limiting groove are respectively rotatably connected to the first limiting rod. The end of each first limiting rod near the first limiting rod is arc-shaped and has multiple gear teeth. The top and bottom of each first limiting rod are respectively connected to the groove wall of the limiting groove. The spring is used to keep the first limiting rod in a horizontal state when it is not subjected to external force.

[0008] A second limiting rod is provided at the location corresponding to the limiting groove on the first side wall, arranged along the second horizontal direction. The two ends of the second limiting rod are respectively provided with teeth for meshing with the gear teeth of the first limiting rod.

[0009] Preferably, the sealing baffle includes two half-baffles, which are spliced ​​together to form an integral structure; each half-baffle has a second sealing window in the middle and a half-accommodating groove at the top, and the two half-accommodating grooves are spliced ​​together to form a limiting groove.

[0010] Preferably, a bushing is embedded in the through hole for the floating shaft of the clamping roller to pass through, so as to reduce friction with the floating shaft.

[0011] This invention also proposes a glass forming apparatus that facilitates the assembly and disassembly of clamping rollers. The apparatus comprises a glass forming furnace and a floating roller mechanism as described in any of the preceding claims. The floating roller mechanism includes two floating shafts, two clamping rollers, two bearing seats, two motors, two second horizontal sliding mechanisms, and a first horizontal sliding mechanism. The two second horizontal sliding mechanisms are mounted on the first horizontal sliding mechanism along a second horizontal direction. The first horizontal sliding mechanism drives the two second horizontal sliding mechanisms to slide along a first horizontal direction perpendicular to the second horizontal direction. The two bearing seats are correspondingly mounted on the two second horizontal sliding mechanisms, and the two second horizontal sliding mechanisms drive the two bearing seats to move closer or further apart along the second horizontal direction. The first ends of the two floating shafts rotate with the bearings of the two bearing seats, and the second ends of the two floating shafts pass through two bushings and are coaxially fixed to the two traction rollers. The two motors are respectively mounted on the two second horizontal sliding mechanisms and are respectively driven and connected to the first ends of the two floating shafts.

[0012] Preferably, each bearing housing is fixedly connected to a connecting housing, which is used to engage with the bushing.

[0013] Preferably, the outer peripheral wall of the bushing has multiple axial sections along the circumferential direction, and the inner surface of the connecting housing forms a contact surface that matches the axial sections.

[0014] Preferably, each contact surface is provided with a positioning block, the axially extending groove matching the positioning block is provided on the axially tangential surface, and the end of the bushing away from the sealing baffle is provided with an avoidance notch for the positioning block to enter and exit the groove.

[0015] Preferably, a positioning flange is provided at the end of the connecting housing away from the bearing seat, the positioning flange has a second oblong hole, and a second oblong block for insertion into the second oblong hole is provided at the corresponding position of the sealing baffle.

[0016] In this invention, the proposed glass forming apparatus and glass forming furnace with convenient clamping roller assembly and disassembly allows for easy replacement of the clamping rollers. First, the clamps are opened, and then the first horizontal sliding mechanism is activated to remove the two clamping rollers from the furnace body. This causes the sealing baffle to separate from the first sealing window, enabling rapid opening of the first sealing window and facilitating the replacement of the clamping rollers. Therefore, this invention can quickly open the first sealing window when clamping rollers need to be replaced without affecting the flexible floating of the clamping rollers.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-4 The present invention proposes a glass forming furnace with convenient clamping roller disassembly and assembly, comprising: a furnace body 1, wherein a first sealing window and a window sealing mechanism for covering and sealing the first sealing window are provided on the first side wall of the furnace body 1;

[0024] The window sealing mechanism includes two clamps 2 and a sealing baffle 3. The two clamps 2 are respectively fixed on the first sidewalls on the left and right sides of the first sealing window. The sealing baffle 3 has two second sealing windows arranged in the middle along the second horizontal direction. Each second sealing window has a sliding plate 4 that slides along the second horizontal direction. The sliding plate 4 has a through hole for the clamping roller to pass through. The left and right sides of the sealing baffle 3 are respectively provided with clamp receiving platforms 6 for pressing with the clamps 2. The clamps 2 press against the clamp receiving platforms 6 so that the sealing baffle 3 seals and covers the first sealing window.

[0025] When the clamping roller needs to be replaced, the clamping pliers 2 can be opened to remove the clamping roller. The removal of the clamping roller will simultaneously cause the sealing baffle 3 to separate from the first sealing window, thereby realizing the rapid opening of the first sealing window and facilitating the replacement of the clamping roller. Moreover, the sliding of the slide plate 4 can ensure the flexibility of the clamping roller to float left and right.

[0026] In order to enable the sealing baffle 3 to accurately cover the first sealing window, in this embodiment, the sealing baffle 3 is provided with a plurality of first waist-shaped holes 31 spaced apart along the circumference, and a first waist-shaped block matching the first waist-shaped hole 31 is provided on the first side wall at the position corresponding to the first waist-shaped hole 31. The first waist-shaped block is used to be inserted into the corresponding first waist-shaped hole 31 when the sealing baffle 3 seals and covers the first sealing window.

[0027] like Figure 3 and Figure 4 As shown, in this embodiment, the sealing baffle 3 has a limiting groove extending in the second horizontal direction on the side facing the first sidewall. The left and right sides of the limiting groove are respectively rotatably connected to the first limiting rod 7. The end of each first limiting rod 7 near the first limiting rod 7 is arc-shaped and has multiple gear teeth. The top and bottom of each first limiting rod 7 are respectively connected to the groove wall of the limiting groove. The spring is used to keep the first limiting rod 7 in a horizontal state when it is not subjected to external force.

[0028] A second limiting rod 12 is provided at the location corresponding to the limiting groove on the first side wall, and is arranged along the second horizontal direction. The two ends of the second limiting rod 12 are respectively provided with teeth for meshing with the gear teeth of the first limiting rod 7.

[0029] With this configuration, the gear teeth on the first limiting rod 7 and the teeth of the second limiting rod 12 can limit the sealing baffle 3 in the vertical direction. Moreover, the rotational configuration of the first limiting rod 7 and the spring configuration facilitate the engagement and separation of the gear teeth and the teeth of the second limiting rod 12.

[0030] Specifically, the limiting groove is located at the top of the sealing baffle 3.

[0031] In this embodiment, a bushing 5 is embedded in the through hole through which the floating shaft 11 for holding the roller passes, so as to reduce friction with the floating shaft 11.

[0032] Specifically, the inner diameter of the bushing 5 is slightly larger than the diameter of the clamping roller by 2 to 3 mm.

[0033] In this embodiment, the sealing baffle 3 includes two half-baffles, which are spliced ​​together to form an integral structure; each half-baffle has a second sealing window in the middle and a half-accommodating groove at the top of each half-baffle, which are spliced ​​together to form a limiting groove to facilitate the installation and disassembly of the floating shaft 11 and the sealing baffle 3.

[0034] Reference Figure 5The present invention also proposes a glass forming apparatus that facilitates the assembly and disassembly of clamping rollers, comprising a glass forming furnace and a floating roller mechanism as described in any of the above claims. The floating roller mechanism includes two floating shafts 11, two clamping rollers, two bearing seats 10, two motors, two second horizontal sliding mechanisms, and a first horizontal sliding mechanism. The two second horizontal sliding mechanisms are mounted on the first horizontal sliding mechanism along the second horizontal direction, and the first horizontal sliding mechanism is used to drive the two second horizontal sliding mechanisms to slide along the first horizontal direction perpendicular to the second horizontal direction. The two bearing seats 10 are mounted on the two second horizontal sliding mechanisms in a one-to-one correspondence, and the two second horizontal sliding mechanisms are used to drive the two bearing seats 10 to move closer to or further away from each other along the second horizontal direction. The first ends of the two floating shafts 11 rotate with the bearings of the two bearing seats 10 respectively, and the second ends of the two floating shafts 11 pass through two bushings 5 ​​respectively and are coaxially fixed with the two traction rollers in a one-to-one correspondence. The two motors are mounted on the two second horizontal sliding mechanisms respectively and are driven and connected to the first ends of the two floating shafts 11 in a one-to-one correspondence.

[0035] With this setup, when the clamping rollers need to be replaced, the clamp 2 is opened first, and then the first horizontal sliding mechanism is activated to remove the two clamping rollers from the furnace body 1, thereby causing the sealing baffle 3 to separate from the first sealing window, realizing the rapid opening of the first sealing window, thus facilitating the replacement of the clamping rollers.

[0036] In a further embodiment, each bearing housing 10 is fixedly connected to a connecting housing 8, which is used to engage with the bushing 5.

[0037] With this configuration, after the clamping roller is replaced, the connecting housing 8 can be moved by the first horizontal sliding mechanism to engage the bushing 5, thereby driving the bushing 5 and the sealing baffle 3 to move along the first horizontal direction until the sealing baffle 3 automatically abuts against the first sealing window, avoiding manual intervention. The weight of the bushing 5, the sliding plate 4 and the sealing baffle 3 are all borne by the connecting housing 8, reducing the friction between the bushing 5 and the floating shaft 11.

[0038] In a further embodiment, the outer peripheral wall of the bushing 5 is provided with a plurality of axial sectional surfaces along the circumferential direction, and the inner surface of the connecting housing 8 forms a contact surface that matches the axial sectional surfaces, so as to increase the positioning accuracy of the connecting housing 8 and the bushing 5.

[0039] In a further embodiment, each contact surface is provided with a positioning block, and the axially extending groove matching the positioning block is provided on the axial cross-section. The end of the bushing 5 away from the sealing baffle 3 is provided with an avoidance notch for the positioning block to enter and exit the groove, so as to limit the axial length of the connection between the connecting housing 8 and the bushing 5 and further improve the positioning accuracy.

[0040] In a further embodiment, a positioning flange 9 is provided at the end of the connecting housing 8 away from the bearing seat 10. The positioning flange 9 has a second oblong hole. The sealing baffle 3 is provided with a second oblong block 32 at the corresponding position of the second oblong hole for insertion into the second oblong hole, so as to improve the stability of the connection between the bushing 5 and the sealing baffle 3 and the connecting housing 8 during the movement, thereby further reducing the friction between the bushing 5 and the floating shaft 11. Moreover, after the sealing baffle 3 is sealed and covered by the first sealing window by the clamp 2 on the clamp receiving platform 6, the connecting housing 8 is pulled back by the first horizontal sliding mechanism to separate the second oblong hole from the second oblong block 32, that is, from the sealing baffle 3, so that the clamping roller is in a suitable position.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
