Description

Technical Field

[0001] This utility model belongs to the field of glass annealing technology, specifically relating to a glass annealing furnace speed reducer that is easy to change quickly. Background Technology

[0002] In the glass manufacturing process, the annealing furnace is a key piece of equipment used to eliminate residual stress inside the glass and ensure product quality. The smooth and uniform conveying of glass sheets within the furnace is typically achieved by a transmission system, with the speed reducer serving as the core power component. Its performance directly affects the stability of the conveying process. However, because annealing furnaces are usually located in harsh environments with high temperatures and dust, the speed reducer is prone to wear, malfunction, or requires regular maintenance after prolonged operation.

[0003] In existing technologies, speed reducers are typically fixed directly to the frame or furnace structure using multiple sets of bolts. When replacing a speed reducer, operators need to use special tools to unscrew multiple bolts one by one, a cumbersome and time-consuming process. This is especially difficult in confined spaces or high-temperature environments, severely impacting production efficiency and increasing safety risks for operators. Furthermore, after replacement or maintenance, the tension of the relevant conveyor belts or chains often needs to be readjusted. Existing annealing furnace conveyor belts are not easy to adjust, further increasing the workload after speed reducer replacement. Therefore, we propose a speed reducer for glass annealing furnaces that is easy to replace quickly. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a glass annealing furnace speed reducer that is easy to replace quickly, so as to solve the problems mentioned in the background art, where the speed reducer is usually directly fixed to the frame or furnace structure by multiple sets of bolts, the replacement process is cumbersome and time-consuming, and the existing annealing furnace conveyor belt is not easy to adjust the tension, which increases the workload after replacing the speed reducer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glass annealing furnace reducer that is easy to quickly replace, comprising an annealing furnace body, a fixing plate fixedly connected to one side of the rear end of the annealing furnace body, four sets of support legs fixedly connected to the bottom of the fixing plate, a reducer mounted on the top of the fixing plate, and a mounting bracket mounted on the bottom of the reducer. Through holes are provided at the top and bottom of the four corners of the mounting bracket, sleeves are rotatably connected to the four corners of the mounting bracket, and fixing nuts are rotatably connected to the top of the sleeves. Mounting structures are provided at the four corners of the fixing plate, and the mounting structures include sliding grooves, with sliders slidably connected inside the sliding grooves. A connecting rod is fixedly connected to the bottom of the slider, a handle is fixedly connected to the bottom of the connecting rod, a spring is fixedly connected to the top of the slider, and a stud is fixedly connected to the top of the slider. Adjustment structures are provided on both sides of the front end of the annealing furnace body. The adjustment structure includes a fixed frame, two sets of guide blocks are fixedly connected to the surface of the fixed frame, a sliding seat is slidably connected to the surface of the guide block, a limit groove is opened at one end of the sliding seat, a threaded sleeve is fixedly connected to one end of the fixed frame, a threaded rod is rotatably connected inside the threaded sleeve, a locking nut is rotatably connected to the surface of the threaded rod, and a limit block is fixedly connected to one end of the threaded rod.

[0006] Preferably, the reducer is connected to the mounting bracket by bolts, and the sleeve is rotatably connected to the four corners of the mounting bracket through the four sets of through holes at the top.

[0007] Preferably, the radius of the slider is larger than the radius of the connecting rod and the stud, the spring is sleeved on the outside of the stud, and the two ends of the spring are fixedly connected to the top of the slider and the top of the inner wall of the groove, respectively.

[0008] Preferably, the radius of the through hole is larger than the radius of the stud, the stud is slidably connected in the through hole, and the sleeve and the fixing nut are both provided with threaded grooves that match the stud.

[0009] Preferably, the two sets of sliders are respectively disposed at the top and bottom of the fixed frame, and the sliding seat is slidably connected between the two sets of guide blocks.

[0010] Preferably, one end of the threaded rod passes through the inner wall of one side of the limiting groove and is fixedly connected to the limiting block. The radius of the limiting block is larger than the radius of the threaded rod, and the limiting block is rotatably connected in the limiting groove.

[0011] Preferably, the locking nut and the threaded sleeve are respectively disposed at both ends of the side surface of the fixing frame, and the threaded sleeve and the locking nut are provided with threaded grooves that match the threaded rod inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This glass annealing furnace reducer, which is easy to replace quickly, is equipped with a sleeve, a fixing nut, and an installation structure. During installation, the through holes at the four corners of the mounting bracket are aligned with the studs. The mounting bracket is placed on top of the fixed plate. Pushing the handle upwards moves the slider and studs upwards via the connecting rod. The slider compresses the spring, and the studs contact the bottom of the sleeve. After rotating the sleeve, the studs move upwards in conjunction with the threaded groove. The fixing nut locks the studs in place. During disassembly, the fixing nut is rotated to unscrew the studs from the top. The sleeve is rotated to allow the studs to exit from the sleeve. Under the action of the spring, the slider moves downwards, causing the studs to move down and fall below the through holes. At this point, the reducer, along with its mounting bracket at the bottom, can be lifted upwards from the fixed plate, facilitating installation and disassembly. The entire process is time-saving and labor-saving, requiring no additional tools to disassemble multiple fasteners. It is particularly advantageous in harsh working conditions such as high temperature and confined spaces.

[0013] 2. This glass annealing furnace reducer, which is easy to replace quickly, is equipped with an adjustment structure. When the reducer is replaced or the conveyor belt is loose, the locking nut is loosened, and then the threaded rod is rotated to make the limit block drive the sliding seat to move. The sliding seat moves stably along the guide block, driving the bearing seat (or other supporting components of the conveyor wheel / sprocket) connected to it to move, thereby conveniently adjusting the tension of the conveyor belt or chain. After adjustment, the locking nut is tightened to fix the position of the threaded rod, ensuring a stable and reliable tension state, eliminating the need for a complicated tensioning device adjustment process.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 One embodiment provided by this utility model: A glass annealing furnace speed reducer that is easy to quickly replace includes an annealing furnace body 1. A fixing plate 2 is fixedly connected to one side of the rear end of the annealing furnace body 1. Four sets of support legs 21 are fixedly connected to the bottom of the fixing plate 2. A speed reducer 3 is installed on the top of the fixing plate 2. A mounting bracket 31 is installed at the bottom of the speed reducer 3. Through holes 32 are opened at the top and bottom of the four corners of the mounting bracket 31. Sleeves 33 are rotatably connected at the four corners of the mounting bracket 31. A fixing nut 34 is rotatably connected to the top of the sleeve 33. An installation structure 4 is provided at the four corners of the fixing plate 2. The installation structure 4 includes a slide groove 41. A slider 42 is slidably connected inside the slide groove 41. A connecting rod 43 is fixedly connected to the bottom of the slider 42. The bottom of the connecting rod 43 is fixed. A handle 44 is connected to the top of the slider 42, a spring 45 is fixedly connected to the top of the slider 42, and a stud 46 is fixedly connected to the top of the slider 42. Adjustment structures 5 are provided on both sides of the front end of the annealing furnace body 1. The adjustment structure 5 includes a fixed frame 51. Two sets of guide blocks 52 are fixedly connected to the surface of the fixed frame 51. A sliding seat 53 is slidably connected to the surface of the guide block 52. A limit groove 54 is provided at one end of the sliding seat 53. A threaded sleeve 55 is fixedly connected to one end of the fixed frame 51. A threaded rod 56 is rotatably connected inside the threaded sleeve 55. A locking nut 57 is rotatably connected to the surface of the threaded rod 56. A limit block 58 is fixedly connected to one end of the threaded rod 56. A sleeve 33, a fixing nut 34, and an installation structure 4 are provided. During installation, align the through holes 32 at the four corners of the mounting bracket 31 with the studs 46. Place the mounting bracket 31 on top of the fixing plate 2. Push the handle 44 upwards, which, through the connecting rod 43, drives the slider 42 and studs 46 upwards. The slider 42 compresses the spring 45, and the studs 46 contact the bottom of the sleeve 33. After rotating the sleeve 33, the studs 46 move upwards, engaging with the threaded groove. The studs 46 are then locked in place by the fixing nut 34. During disassembly, rotate the fixing nut 34 to unscrew it from the top of the studs 46. Rotate the sleeve 33 to disengage the studs 46 from inside the sleeve 33. Under the action of the spring 45, the slider 42 moves downwards, causing the studs 46 to move downwards and descend below the through holes 32. At this point, the reducer 3, along with its mounting bracket 31 at the bottom, is ready for disassembly. The entire assembly can be lifted off the fixed plate 2, saving time and effort. It does not require any additional tools to disassemble multiple fasteners, which is especially advantageous in harsh working conditions such as high temperature and confined space. An adjustment structure 5 is provided. When the reducer 3 is replaced or the conveyor belt becomes loose, the locking nut 57 is loosened, and then the threaded rod 56 is rotated to make the limit block 58 move the sliding seat 53. The sliding seat 53 moves stably along the guide block 52, which moves the bearing seat or other supporting components of the conveyor wheel / sprocket connected to it, thereby conveniently adjusting the tension of the conveyor belt or chain. After adjustment, the locking nut 57 is tightened to fix the position of the threaded rod 56, ensuring a stable and reliable tension state, eliminating the need for a complicated tensioning device adjustment process.

[0018] Furthermore, the reducer 3 is connected to the mounting bracket 31 by bolts, and the sleeve 33 is rotatably connected to the four corners of the mounting bracket 31 through the four sets of through holes 32 at the top, which clarifies the installation position and status of the sleeve 33 and provides a basis for its cooperation with the stud 46.

[0019] Furthermore, the radius of the slider 42 is larger than the radius of the connecting rod 43 and the stud 46, which is a necessary condition to ensure that the slider 42 can slide reliably in the groove 41 and will not be pulled out. The spring 45 is sleeved on the outside of the stud 46, and the two ends of the spring 45 are fixedly connected to the top of the slider 42 and the top of the inner wall of the groove 41, respectively. When the fixing nut 34 and the stud 46 are locked together, the spring 45 is in a compressed state, providing the elastic force for the stud 46 to return downward.

[0020] Furthermore, the radius of the through hole 32 is larger than the radius of the stud 46. The stud 46 is slidably connected inside the through hole 32, which is a necessary condition to ensure that the stud 46 can pass smoothly through the through hole 32 for installation and alignment. The sleeve 33 and the fixing nut 34 are both provided with threaded grooves that match the stud 46, clarifying the threaded connection relationship between the stud 46 and the sleeve 33 and the fixing nut 34. This is the core of achieving quick locking / unlocking.

[0021] Furthermore, two sets of sliders 42 are respectively set at the top and bottom of the fixed frame 51, and the sliding seat 53 is slidably connected between the two sets of guide blocks 52. The double track guide ensures the stability of the movement of the sliding seat 53.

[0022] Furthermore, one end of the threaded rod 56 passes through the inner wall of one side of the limiting groove 54 and is fixedly connected to the limiting block 58. The radius of the limiting block 58 is larger than the radius of the threaded rod 56. The limiting block 58 is larger than the threaded rod 56 to prevent the threaded rod 56 from completely coming out of the limiting groove 54. The limiting block 58 is rotatably connected in the limiting groove 54. When the threaded rod 56 is rotated, the sliding seat 53 can be moved through the cooperation between the limiting block 58 and the limiting groove 54.

[0023] Furthermore, the locking nut 57 and the threaded sleeve 55 are respectively disposed at both ends of the side surface of the fixing frame 51. The threaded sleeve 55 and the locking nut 57 are provided with threaded grooves that match the threaded rod 56. The threaded sleeve 55 provides initial rotational support and limit, and the locking nut 57 is used to lock the position of the threaded rod 56 after adjustment.

[0024] Working principle: During installation, align the through holes 32 at the four corners of the mounting bracket 31 with the studs 46. Place the mounting bracket 31 on top of the fixing plate 2. Push the handle 44 upwards, which will drive the slider 42 and studs 46 upwards via the connecting rod 43. The slider 42 will compress the spring 45, and the studs 46 will contact the bottom of the sleeve 33. After rotating the sleeve 33, the studs 46 will move upwards in conjunction with the threaded groove, and the studs 46 will be locked in place by the fixing nut 34. During disassembly, rotate the fixing nut 34 to remove the studs 46 from the screws 46. 6. Unscrew the top and rotate the sleeve 33 to disengage the stud 46 from the sleeve 33. Under the action of the spring 45, the slider 42 moves down, causing the stud 46 to move down and fall below the through hole 32. At this time, the reducer 3 and its bottom mounting bracket 31 can be lifted up and away from the fixed plate 2. When it is necessary to adjust the tension of the conveyor belt or chain, first loosen the locking nut 57, and then rotate the threaded rod 56. The threaded rod 56 moves linearly through the threaded engagement with the threaded sleeve 55. The threaded rod 56 drives the limiting block 58 at its end to move. Since the limiting block 58 is located in the limiting groove 54 of the sliding seat 53, the movement of the limiting block 58 will push or pull the sliding seat 53. Under the restriction of the upper and lower guide blocks 52, the sliding seat 53 can only move parallel to the fixed frame 51. The movement of the sliding seat 53 drives the bearing seat and the transmission wheel / sprocket installed at its front end, thereby changing the relative position between the transmission wheel / sprocket and realizing the tensioning or loosening of the conveyor belt or chain. After adjusting to a suitable tension, the locking nut 57 is rotated to a position close to the side of the fixed frame 51 and tightened. The locking nut 57 locks the position of the threaded rod 56 relative to the fixed frame 51, preventing the threaded rod 56 from rotating on its own due to vibration and other factors, thereby ensuring the stability of the tension of the transmission system.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
