[0002] At present, domestic liquid crystal glass substrate mainly uses the overflow method to produce, and the edge puller in the forming furnace is an important part of glass production, which pulls the edge of the glass. The edge puller is arranged at both ends of the glass plate width, and clamps the glass strip when the glass strip (gel) shrinks. The edge pulling shaft of the clamped glass makes the both sides of the glass strip not shrink again under the action of cooling, and forms a stable width glass strip.
[0003] In actual production, the edge pulling shaft is inserted into the furnace from a specific window on the forming furnace, and the window is sealed by a sealing baffle. In order to adjust the height of the edge puller clamping the glass strip when some process changes, the sealing baffle of the window is slid to the corresponding position and is fastened by a limiting screw during the height adjustment process of the edge puller. Because the temperature of the window is very high and the adjustment frequency is not high, the screw for limiting is easy to burn out. After burning out, the sealing baffle of the window basically cannot slide again, which seriously affects the process quality control of the process personnel. CONTENT OF THE UTILITY MODEL

The sealing plate assembly is movably installed on the guide assembly and located in the first plane, and can move in the first direction on the first plane and seal the window. The limiting assembly is installed on the edge puller and located in the first plane. When the limiting assembly is switched from the initial first state to the second state in the first plane, it will abut against the sealing plate assembly from the second direction perpendicular to the first direction, so as to lock the movement of the sealing plate assembly in the first direction along the guide assembly. When the limiting assembly is restored from the second state to the first state in the first plane, it will move away from the sealing plate assembly from the second direction, so as to unlock the movement of the sealing plate assembly in the first direction along the guide assembly.

[0010] This utility model proposes a window limiting mechanism for an edge-pulling machine. Its advantages include: using a cam instead of screws and nuts for tightening and limiting, effectively preventing the window from becoming stuck due to thread burn-out; the guide assembly provides a solid foundation for the movement of the sealing plate assembly; the first and second plates are symmetrically distributed on both sides of the window, their length direction parallel to the first direction, forming a guide track; and the first and second grooves penetrate the plates, allowing the first and second protrusions of the sealing plate assembly to fit and install, ensuring that the sealing plate assembly can move flexibly on the guide assembly while tightly fitting the window, with smooth and stable movement. The limiting component can switch states. When adjusting the glass clamping height of the edge-pulling machine during production, the initial limiting component is in the first state, allowing the sealing plate assembly to move freely along the guide assembly to adapt to initial changes in window position; once adjusted, it switches to the second state, allowing it to press against the sealing plate assembly from a second direction perpendicular to the first direction, locking its movement along the guide assembly in the first direction. When subsequent process changes require readjustment, it can smoothly return to the first state to unlock the sealing plate assembly, meeting different process requirements. A second cam is set on the outer wall of the collar to correspond to the first cam. The fixed frame at the end of the top block can accommodate the second cam. When the state of the limit component is switched, each component moves reasonably, which avoids interference between components and makes full use of the limited space of the edge-pulling machine, so that the mechanism can operate efficiently in a compact environment.

[0014] refer to Figs. 1-3 This utility model proposes a window limiting mechanism for an edge-pulling machine. The window is set on the outer wall of the edge-pulling machine 1. The entire limiting mechanism mainly includes a sealing plate assembly 2, a guide assembly 3, and a limiting assembly.
[0015] The guide assembly 3 is fixedly installed on the edge pulling machine 1 as the basis for the movement of the sealing plate assembly 2, the length direction of which is defined as the first direction and is located in the first plane parallel to the outer wall of the edge pulling machine 1, ensuring that the subsequent sealing plate assembly 2 can move stably. The guide assembly 3 is specifically composed of a first plate body 31, a first groove body 32, a second plate body 33 and a second groove body 34. The first plate body 31 and the second plate body 33 are symmetrically distributed on both sides of the window, and the length direction of each of them is parallel to the first direction, providing a guide rail for the sealing plate assembly 2. The first groove body 32 is provided on the first plate body 31 along the first direction, and the second groove body 34 is provided on the second plate body 33 along the first direction, so that the sealing plate assembly 2 can smoothly slide on the first groove body and the second groove body 34. The sealing plate assembly 2 is composed of a plate body and a first protrusion 21 and a second protrusion 22 fixedly installed on both sides of the plate body. The first protrusion 21 is adaptively installed on the first groove body 32, and the second protrusion 22 is adaptively installed on the second groove body 34, which ensures that the sealing plate assembly 2 can move flexibly and closely fit the window on the guide assembly 3.
[0016] The limiting assembly is installed on the edge pulling machine 1 and is also located in the first plane. When the production process needs to adjust the height of the edge pulling machine for clamping the glass, the limiting assembly can play its switching function. In the initial state, the limiting assembly is in the first state, and at this time, the sealing plate assembly 2 can move freely along the guide assembly 3 to adapt to the preliminary change of the window position. After adjustment, the limiting assembly is switched from the initial first state to the second state, which will abut against the sealing plate assembly 2 from the second direction perpendicular to the first direction, lock the sealing plate assembly 2 and lock its movement in the first direction along the guide assembly 3. When the subsequent process needs to be adjusted again, the limiting assembly smoothly recovers from the second state to the first state and moves away from the sealing plate assembly 2 from the second direction, unlocking the sealing plate assembly 2 so that it can move again to meet the new process requirements.
[0017] Specifically, the limiting assembly is composed of a threaded hole, a bolt 10, a shaft ring 9, a first cam 8 and a connecting block 11. The threaded hole is provided on the edge trimming machine 1. The end of the bolt 10 is connected to the threaded hole, providing a mounting base for the entire limiting assembly. The shaft ring 9 is coaxially movably sleeved on the outer wall of the bolt 10 and can rotate freely around the bolt 10. The first cam 8 is fixedly installed on the outer wall of the shaft ring 9 and is coaxially arranged with the shaft ring 9, ensuring the concentricity and stability of rotation. The connecting block 11 is fixedly installed on the side surface of the first cam 8 and is also coaxially arranged with the shaft ring 9. The connecting block 11 is a hexagonal nut, which is convenient for rotating the connecting block 11 and the shaft ring 9 by a tool, making the linkage between the components more efficient. On the first plate body 31, a through hole 4 is arranged in the second direction. The through hole 4 is located on the first plane, and a top block 5 that can move in the second direction is installed inside the through hole 4. When the limiting assembly switches from the open state to the closed state, the connecting block 11 drives the shaft ring 9 and the first cam 8 to rotate around the axis of the bolt 10. The maximum radius of the first cam 8 gradually abuts against the top block 5 from the side surface, driving the top block 5 to move in the second direction on the first plane. As the top block 5 moves, the friction between the sealing plate assembly 2 and the guide assembly 3 increases, thereby locking the sealing plate assembly 2. This state is the second state.
[0018] A second cam 7 is also fixedly installed on the outer wall of the shaft ring 9, coaxially arranged with the shaft ring 9, and corresponding to the first cam 8. The length of the top block 5 is greater than the length of the through hole 4 in the second direction, so that the top block 5 has enough travel to control the friction during movement. A frame 6 is fixedly installed on the end of the top block 5. The frame 6 is located between the outer wall of the edge trimming machine 1 and the first plane and can accommodate the second cam 7. When the limiting assembly switches from the second state to the first state, the shaft ring 9 rotates in the opposite direction, and the first cam 8 no longer abuts against the top block 5. The first cam 7 pushes the frame 6 to move in the second direction away from the window, thereby pushing the top block 5 back to its original position. This avoids interference between the components and optimizes the spatial layout of the entire mechanism, allowing the mechanism to operate efficiently in a compact edge trimming machine environment.
[0019] The angle between the projection line of the maximum radius of the first cam 8 on the first plane and the projection line of the maximum radius of the second cam 7 on the first plane is set to 60°. They are mutually offset. When switching from the first state to the second state, the first cam 8 can push the top block 5 to compress and lock the sealing plate assembly. When switching from the second state back to the first state, the second cam 7 can push the frame 6 to drive the top block 5 back to its original position. In this way, the top block 5 is driven to move in the most reasonable way, ensuring sufficient friction to lock the sealing plate assembly 2 and facilitating the switching of states, ensuring the reliability and stability of the window sealing during each process adjustment.
