Description

Technical Field

[0001] This invention relates to the field of glass substrate manufacturing technology, specifically to a heater base for heating glass substrates during production. Background Technology

[0002] Currently, the overflow method is widely used in the production process of LCD substrates in China, offering advantages such as high efficiency and stability. However, during the manufacturing of LCD substrate glass, the molten glass at the brick tip baffle position is prone to crystallization due to factors such as improper temperature control and uneven composition. Crystallization not only reduces the fluidity of the molten glass, affecting production efficiency and product quality, but can also cause equipment malfunctions, severely impacting production. To address this issue, a specialized brick tip baffle heater is typically used to heat the brick tip. This heater effectively prevents crystallization by precisely controlling the temperature of the brick tip. The brick tip baffle heater employs advanced heating technology and materials, enabling uniform heating of the molten glass at the brick tip position, thereby improving the fluidity of the molten glass and ensuring the continuity and stability of production. Furthermore, the brick tip baffle heater offers advantages such as energy saving, environmental friendliness, and ease of operation. By optimizing the heating method and control strategy, energy consumption can be significantly reduced, lowering production costs. Simultaneously, the heater's design fully considers ease of operation, allowing production personnel to easily adjust heating parameters and achieve precise control of the production process.

[0003] In practical applications, we have found that when the brick tip baffle heater heats the brick tip, the heat will radiate onto the normal glass strip, causing abnormalities in the edge plate process of the normal glass strip. At this time, the radiation range of the heater can be controlled by adjusting the height of the front eaves of the heater. However, the existing heater base does not have the function of adjusting the height of the front eaves. In order to meet the production process requirements, the entire heater needs to be replaced. Therefore, providing a base that can adjust the height of the front eaves after the heater is installed has become an urgent problem for relevant technical personnel to solve. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the fact that existing heater bases do not have the function of adjusting the height of the front eaves, and that the entire heater needs to be replaced in order to meet production process requirements.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A heater base for heating in glass substrate production includes a heater bracket. A moving mechanism is installed inside the heater bracket. A driving gear is rotatably mounted on one side of the heater bracket. Driven gears are installed at both ends of the driving gear. A linkage mechanism is installed on the other side of the driven gear extending into the heater bracket. The linkage mechanism includes a connecting rod and a cam. A cam is installed on the other side of the rear end of the connecting rod. One side of the connecting rod is connected to the driven gear. Mounting grooves are opened inside the heater bracket at both ends of the cam. A blocking mechanism is slidably mounted inside the mounting grooves.

[0007] A pointer is coaxially mounted on the drive gear, a scale corresponding to the pointer is mounted on one side of the heater bracket, and a locking mechanism adapted to the driven gear is mounted on one side of the heater bracket.

[0008] Preferably, the shielding mechanism includes a front eaves plate and side pulleys. The front eaves plate is movably installed inside the mounting groove, and grooves are provided at both ends of the front eaves plate. Side pulleys are rotatably installed inside the grooves.

[0009] Preferably, the shielding mechanism further includes an auxiliary wheel, a movable block, a first spring, and a pull rope. The heater bracket has a groove inside that matches the movable block. The movable block is slidably installed inside the groove. The movable block is connected to the front eaves plate by a pull rope. The pull rope is surrounded by a first spring.

[0010] Preferably, an auxiliary wheel is rotatably mounted inside the heater bracket at the bottom of the front eaves, and the pull rope is wrapped around the outer periphery of the auxiliary wheel.

[0011] Preferably, the locking mechanism includes a slide rail, a movable plate, a pressure rod, a locking block, a serrated bar, and a locking groove. A serrated bar is slidably installed inside the slide rail, and a locking groove is provided on the other side of the serrated bar. The serrated bar meshes with a driven gear. A movable plate is slidably installed inside the slide rail. A locking block that matches the locking groove is installed on one side of the movable plate, and a pressure rod extending out of the slide rail is installed on one side of the movable plate.

[0012] Preferably, the locking mechanism further includes a second spring and a pressure ring. The slide rail has an inner groove, and a pressure ring that matches the inner groove is installed around the pressure rod. A second spring is sleeved around the pressure rod on the other side of the pressure ring.

[0013] Preferably, the moving mechanism includes a mounting plate, a slider, a threaded rod, and bearing seats. The bearing seats are installed at both ends inside the heater bracket. The threaded rod is rotatably installed between the bearing seats. The slider is rotatably installed around the threaded rod. The mounting plate is installed on the top of the slider.

[0014] Preferably, the moving mechanism further includes a hand crank, on one side of the threaded rod, the hand crank extending out of the heater bracket, and the hand crank and the heater bracket are rotatably mounted.

[0015] Preferably, a limiting bearing is sleeved on the periphery of one side of the connecting rod, and the limiting bearing is located inside the heater bracket.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention drives two driven gears simultaneously by controlling the rotation angle of the driving gear, which in turn drives the cam to rotate through the rotation of the connecting rod. The rotation angle of the driving gear is controlled by the pointer and the dial, thereby precisely controlling the lifting height of the front eaves board. This controls the radiation range of the heater, ensuring that the height of the front eaves board meets the usage requirements under different production conditions, avoiding the need to replace the heater and ensuring production progress.

[0018] 2. The present invention is equipped with a locking mechanism, which can lock the position of the front eaves after the front eaves have been adjusted in height. The active gear meshes with two driven gears at the same time, and the two driven gears rotate in the same direction. At the same time, two connecting rods and cams are set to reduce the weight borne by each cam.

[0019] 3. This invention utilizes a structure including side pulleys, pull ropes, and movable blocks. When the front eaves panel rises, the movable block, driven by the pull rope, compresses the first spring. When the front eaves panel descends, the movable block automatically resets under the push of the first spring. During the reset process, the pull rope pulls the front eaves panel downwards simultaneously. The side pulleys effectively reduce the resistance encountered by the front eaves panel during its lifting and lowering, preventing jamming within the mounting groove during the lifting and lowering process. This allows users to adjust the front eaves panel according to their needs, ensuring the stability of the front eaves panel's lifting and lowering.

[0020] 4. This invention features a movable mechanism that can be disassembled and used according to the size and shape of the heater and the usage requirements. After the movable mechanism is installed, the position of the heater on the heater bracket can be adjusted according to the usage requirements to meet different production needs and optimize the usage process.

[0028] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0029] The present invention provides a heater base for heating in the production of glass substrates, exemplarily, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a heater bracket 1, inside which a moving mechanism 8 is installed. A drive gear 4 is rotatably mounted on one side of the heater bracket 1, and driven gears 3 are mounted at both ends of the drive gear 4. A linkage mechanism 2 is installed on the other side of the driven gear 3 extending into the heater bracket 1. The linkage mechanism 2 includes a connecting rod 201 and a cam 202. The cam 202 is mounted on the other side of the rear end of the connecting rod 201. One side of the connecting rod 201 is connected to the driven gear 3. A limit bearing 11 is sleeved on the outer periphery of one side of the connecting rod 201. The limit bearing 11 is located inside the heater bracket 1. Mounting grooves 10 are opened inside the heater bracket 1 at both ends of the cam 202. A blocking mechanism 7 is slidably mounted inside the mounting grooves 10. A pointer 6 is coaxially mounted on the drive gear 4, and a scale 5 corresponding to the pointer 6 is mounted on one side of the heater bracket 1. The drive gear 4 can be rotated manually or electrically. The driving gear 4 meshes with two driven gears 3 simultaneously, and the two driven gears 3 rotate in the same direction. Two connecting rods 201 and cams 202 are also provided to reduce the weight borne by each cam 202. Specifically, the heater is first installed on the heater bracket 1, the locking mechanism 9 is released, and the driving gear 4 is rotated to drive the two driven gears 3 to rotate in the same direction, which in turn drives the two connecting rods 201 and cams 202 to rotate in the same direction. The shape of the cams 202 can drive the front eaves plate 701 in the shielding mechanism 7 to move vertically in the mounting groove 10. According to the actual use requirements, the height of the front eaves plate 701 is adjusted to control the radiation range of the heater. The higher the front eaves plate 701 is, the smaller its radiation range is, and the lower the front eaves plate 701 is, the larger its radiation range is. The pointer 6 is coaxially mounted on the driving gear 4. The setting of the pointer 6 and the scale 5 makes it easy to judge the height of the front eaves plate 701, which is convenient for operation.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the shielding mechanism 7 includes a front eaves plate 701 and side pulleys 702. The front eaves plate 701 is movably installed inside the mounting groove 10. Grooves are provided at both ends of the front eaves plate 701, and the side pulleys 702 are rotatably installed inside the grooves. The shielding mechanism 7 also includes an auxiliary wheel 703, a movable block 704, a first spring 705, and a pull rope 706. The heater bracket 1 has a groove inside that matches the movable block 704. The movable block 704 is slidably installed inside the groove. The movable block 704 is connected to the front eaves plate 701 by a pull rope 706. The first spring 705 is sleeved around the outside of the pull rope 706. The auxiliary wheel 703 is rotatably installed inside the heater bracket 1 at the bottom of the front eaves plate 701, and the pull rope 706 is wrapped around the outside of the auxiliary wheel 703. The movable block 704 and the first spring 705 are both located inside the groove. The front eaves plate 701 is made of heat-insulating material to block heat radiation.

[0031] Specifically, when the front eaves panel 701 moves up and down inside the mounting groove 10 under the drive of the linkage mechanism 2, the side pulleys 702 installed in the grooves at both ends of the front eaves panel 701 can effectively reduce the resistance encountered by the front eaves panel 701 during the lifting and lowering process, and avoid the front eaves panel 701 getting stuck inside the mounting groove 10 during the lifting and lowering process, so that the user can adjust the front eaves panel 701 according to the needs. During the rising process of the front eaves panel 701, the pull rope 706 will pull the movable block 704 to move inside the groove. At the same time as the movable block 704 moves, it will compress the first spring 705. When the front eaves panel 701 descends... When the movable block 704 is pushed by the first spring 705, it automatically resets. During the reset process, the pull rope 706 pulls the front eaves 701 and moves it downwards at the same time. This avoids the situation where the front eaves 701 cannot automatically reset when the linkage mechanism 2 stops raising and lowering the front eaves 701. By installing the auxiliary wheel 703, the pull rope 706 can be guided to change direction during use. During the movement of the pull rope 706, the auxiliary wheel 703 can be driven to rotate inside the heater bracket 1, which reduces the resistance and wear generated between the pull rope 706 and the heater bracket 1 during the movement, extends the service life of the pull rope 706, and optimizes the use process.

[0032] like Figure 1 , Figure 2 and Figure 4 As shown, the moving mechanism 8 includes a mounting plate 801, a slider 802, a threaded rod 803, and a bearing seat 805. The bearing seats 805 are installed at both ends inside the heater bracket 1. The threaded rod 803 is rotatably mounted between the bearing seats 805. The slider 802 is rotatably mounted around the threaded rod 803. The mounting plate 801 is mounted on the top of the slider 802. The moving mechanism 8 also includes a hand crank 804. A hand crank 804 extending out of the heater bracket 1 is mounted on one side of the threaded rod 803. The hand crank 804 is rotatably mounted to the heater bracket 1.

[0033] Specifically, the moving mechanism 8 and the heater bracket 1 are detachably installed. During use, the moving mechanism 8 can be installed or not depending on the usage requirements. After the moving mechanism 8 is installed, the heater used for glass substrate production is installed on the top of the mounting plate 801. At the same time, the two hand cranks 804 are rotated. During the rotation of the hand cranks 804, the threaded rod 803 is rotated. The bearing seat 805 is used to increase the stability of the threaded rod 803 during rotation. During the rotation of the threaded rod 803, the external thread drives the slider 802 to move laterally. While the slider 802 moves laterally, the mounting plate 801 moves synchronously. Thus, the position of the heater installed on the mounting plate 801 can be adjusted according to the requirements.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a locking mechanism 9 adapted to the driven gear 3 is installed on one side of the heater bracket 1. The locking mechanism 9 includes a slide rail 901, a movable plate 902, a pressure rod 904, a locking block 906, a serrated bar 907, and a locking groove 908. The serrated bar 907 is slidably installed inside the slide rail 901, and a locking groove 908 is opened on the other side of the serrated bar 907. The serrated bar 907 meshes with the driven gear 3. The movable plate 902 is slidably installed inside the slide rail 901, and a locking mechanism 906 is installed on one side of the movable plate 902. The locking mechanism 9 also includes a second spring 903 and a pressure ring 905. The slide rail 901 has an inner groove, and the pressure ring 905 is installed on the periphery of the pressure rod 904 to match the inner groove. The second spring 903 is sleeved on the periphery of the pressure rod 904 on the other side of the pressure ring 905. The slide rail 901 has an inner cavity that allows the movement of the movable plate 902 and the slot 908.

[0035] Specifically, during use, by pushing the pressure rod 904, the pressure rod 904 moves, causing the pressure ring 905 to squeeze the second spring 903. The movable plate 902 moves to the other side under the action of the pressure rod 904, causing the locking block 906 to disengage from the slot 908. After disengagement, the serrated bar 907 moves up and down inside the slide rail 901 under the action of the driven gear 3. When the user releases the pressure rod 904, the pressure ring 905, pushed by the second spring 903, moves the pressure rod 904 and the movable plate 902 to one side to reset. After the movable plate 902 resets, the locking block 906 re-inserts into the slot 908. After insertion, the position of the serrated bar 907 inside the slide rail 901 is limited. After the serrated bar 907 is locked, the driven gear 3 and the driving gear 4 cannot rotate, thereby locking the position of the front eaves plate 701 inside the mounting groove 10.

[0036] The working principle of this invention is as follows: Before use, select whether to install the moving mechanism 8 according to the usage requirements. After the moving mechanism 8 is installed, install the heater used for glass substrate production on the top of the mounting plate 801. At the same time, rotate the two hand cranks 804. During the rotation of the hand cranks 804, the threaded rod 803 is driven to rotate. During the rotation of the threaded rod 803, the external thread drives the slider 802 to move laterally. While the slider 802 moves laterally, it drives the mounting plate 801 to move synchronously. Thus, the position of the heater installed on the mounting plate 801 is adjusted according to the requirements. After the adjustment is completed, push the pressure rod 904. During the movement of the pressure rod 904, it drives the pressure ring 905 to squeeze the second spring 903. The movable plate 902 moves to the other side under the action of the pressure rod 904, causing the locking block 906 to disengage from the slot 908. By rotating the driving gear 4, the two driven gears 3 rotate in the same direction, which in turn drives the two connecting rods 201 and the cam 202 to rotate in the same direction. The shape of the cam 202 allows the front eaves plate 701 in the shielding mechanism 7 to move vertically within the mounting slot 10. According to actual usage requirements, the height of the front eaves plate 701 is adjusted to control the radiation range of the heater. The higher the front eaves plate 701, the smaller its radiation range; the lower the front eaves plate 701, the larger its radiation range. The pointer 6, coaxially mounted on the driving gear 4, and the setting of the pointer 6 and the dial 5 facilitate the adjustment of the heater's radiation range. The height of the front eaves panel 701 is determined by the rotation of the driven gear 3, which drives the serrated bar 907 to slide inside the slide rail 901. After the driven gear 3 stops rotating, the pressure rod 904 is released. Under the push of the second spring 903, the pressure ring 905 drives the pressure rod 904 and the movable plate 902 to move to one side to reset. After the movable plate 902 resets, the locking block 906 re-inserts into the slot 908. After insertion, the position of the serrated bar 907 is limited. After the serrated bar 907 is limited, the driven gear 3 and the driving gear 4 cannot rotate, thus locking the position of the front eaves panel 701 inside the mounting groove 10. Under the drive of the linkage mechanism 2, the front eaves panel 701 moves in the mounting groove. When the front eaves 701 moves up and down inside the mounting groove 10, the side pulleys 702 installed in the grooves at both ends of the front eaves 701 can effectively reduce the resistance encountered by the front eaves 701 during the lifting and lowering process. During the lifting process, the front eaves 701 will use the pull rope 706 to pull the movable block 704 to move inside the groove. While the movable block 704 is moving, it will squeeze the first spring 705. When the front eaves 701 is lowered, the movable block 704 will automatically reset under the push of the first spring 705. During the reset process, the pull rope 706 will pull the front eaves 701 to move downward at the same time, so as to avoid the front eaves 701 getting stuck inside the mounting groove 10 during the lifting and lowering process, so that the user can adjust the front eaves 701 according to the needs.
