Description

Technical Field

[0001] This invention relates to the field of glass annealing, and more specifically to an automated annealing equipment for glass processing. Background Technology

[0002] Glass, as a high-performance inorganic non-metallic material, is widely used in construction, automobiles, electronics, optics, and many other fields. During the glass melting and forming process, the rapid cooling rate and large temperature gradient of the melt generate significant thermal stress within the glass. This internal stress severely affects the mechanical properties, optical properties, and dimensional stability of the glass, leading to brittleness, poor impact resistance, and even failure to meet subsequent processing and usage requirements. Therefore, annealing is an indispensable and crucial step in glass processing.

[0003] Currently, traditional glass annealing processes mainly rely on manual operation and semi-automated equipment. For the annealing of glass test tubes, the drawbacks of traditional equipment are even more pronounced, particularly in the two core stages of material preparation and annealing process control. Firstly, in the material preparation stage, traditional equipment often employs a batch-based, coarse-scale material preparation structure, making it difficult to accurately prepare each glass test tube individually. Due to the small size and large quantity of glass test tubes, manual material preparation is not only extremely labor-intensive but also prone to collisions, scratches, or even breakage due to improper operation, severely impacting product yield. Secondly, in the annealing control stage, traditional equipment often uses a fixed furnace structure, which cannot effectively allow for the rotation of glass test tubes. Since glass test tubes have thin walls and small radial dimensions, the inability to rotate during annealing leads to uneven heating and cooling around the circumference of the test tube, generating thermal stress at different locations on the tube wall. This is especially problematic at irregularly shaped areas such as the test tube opening and bottom, where concentrated stress can easily form, increasing the risk of cracking during use. This significantly reduces annealing efficiency, failing to meet practical application requirements.

[0004] Therefore, there is a need for an automated annealing equipment for glass processing, which aims to solve the above problems. Summary of the Invention

The third connecting shaft is rotatably connected via a fourth synchronous chain, and one end of the second connecting shaft is also rotatably connected via a third synchronous chain.

[0015] As a further embodiment of the present invention, the material changing mechanism further includes a lifting block for driving the blocking roller on the unloading platform away from the limit.

Furthermore, the sequential material changing mechanism, through progressive switching, completes targeted processing at each station in sequence. Compared to the traditional single-furnace overall annealing mode, it can more effectively eliminate residual stress inside the test tubes, achieve continuous production operations, and significantly improve annealing efficiency.

[0022] By employing a rotating annealing mechanism that coordinates progressive station switching with rotation, glass test tubes can rotate at a uniform speed at each annealing station. This synergistic effect further enhances the annealing result. Secondly, the molecular motion within the glass test tubes becomes more balanced during rotation, which helps accelerate the release and dissipation of residual stress. Furthermore, the combination of rotational annealing and progressive station switching further improves the consistency of annealing quality across batches, avoiding performance fluctuations caused by differences in static placement. Finally, the automated rotation drive and station switching work together without requiring manual intervention to adjust the test tube posture, further enhancing the automation and stability of the production process, reducing the uncertainty risks associated with manual operation, and ultimately improving the annealing efficiency of glass test tubes.

[0037] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0038] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0039] Example 1

[0040] See Figures 1-6An automated annealing device for glass processing includes a base plate 1, a feeding platform 2 and an annealing furnace 3 mounted on the base plate 1, a feeding seat 30 for receiving glass test tubes 4 is provided below one side of the feeding platform 2, and the feeding seat 30 has several second feeding slots 32 for placing the glass test tubes 4. The annealing furnace 3 is installed above the feeding seat 30. The device also includes:

[0041] The limiting feeding mechanism is installed on the feeding platform 2 and is used to control the feeding of glass test tubes 4 one by one. The limiting feeding mechanism includes a blocking roller 5 for limiting connection. The blocking roller 5 is movably installed on the feeding platform 2.

[0042] Furthermore, the limiting unloading mechanism also includes a lifting block 6 for driving the blocking roller 5 to perform limiting docking. The lifting block 6 is slidably connected to the unloading platform 2 through the guide rod 7. A spring 8 is provided at the connection between one side of the lifting block 6 and the unloading platform 2. The blocking roller 5 is rotatably connected to the lifting block 6.

[0043] Preferably, during the annealing process, the glass test tubes 4 are arranged one by one at an angle on the unloading platform 2, and the blocking rollers 5 on the unloading platform 2 limit the unloading of the glass test tubes 4 under the elastic limiting action of the spring 8, thereby facilitating subsequent unloading control.

[0044] Example 2

[0045] like Figures 1 to 11 As shown, this embodiment, based on embodiment 1, also includes a sequential material changing mechanism, which is installed on the side of the annealing furnace 3. It is used to drive the glass test tubes 4 on the unloading platform 2 to unload and to switch the glass test tubes 4 on the second discharge trough 32 to their positions one by one. The sequential material changing mechanism includes a first material changing plate 11 and a second material changing plate 28 for material changing drive. The first material changing plate 11 and the second material changing plate 28 are each provided with a plurality of first discharge troughs 12 for receiving and changing materials. The first material changing plate 11 and the second material changing plate 28 are rotatably and movably installed on the side of the discharge seat 30, and a guide plate 31 is provided on the side of the discharge seat 30 near the unloading platform 2.

[0046] Furthermore, the material changing mechanism also includes a first turntable 14 and a first connecting shaft 15 for driving the first material changing plate 11 to perform material changing one by one. The first connecting shaft 15 is fixedly installed on the first turntable 14 and is located at a non-central position of the first turntable 14. The first turntable 14 is rotatably installed on the first material changing plate 11 through the first fixed shaft 13. The first connecting shaft 15 is rotatably installed on the first support plate 16 and the first support plate 16 is fixedly installed on the base plate 1. The first connecting shaft 15 is rotatably connected through the first synchronous chain 17.

[0047] Furthermore, the material changing mechanism also includes a motor 22 for driving the first connecting shaft 15 to rotate. The first connecting shaft 15 is also rotatably connected to a second connecting shaft 19 via a second synchronous chain 18. The second connecting shaft 19 is rotatably mounted on the unloading platform 2. A worm gear 20 is fixedly connected to the second connecting shaft 19. A worm 21 is meshed on the worm gear 20. The worm 21 is fixedly connected to the output shaft of the motor 22. A protective box 23 is provided on the outside of the motor 22.

[0048] Furthermore, the material changing mechanism also includes a second turntable 26 and a third connecting shaft 25 for driving the second material changing plate 28 to perform material changing one by one. The third connecting shaft 25 is fixedly installed on the second turntable 26 and is located at a non-central position of the second turntable 26. The second turntable 26 is rotatably installed on the second material changing plate 28 via a second fixed shaft 27. The third connecting shaft 25 is rotatably installed on a second support plate 45 and the second support plate 45 is fixedly installed on the base plate 1. The third connecting shaft 25 is rotatably connected via a fourth synchronous chain 29. The third connecting shaft 25 is also rotatably connected to one end of the second connecting shaft 19 via a third synchronous chain 24.

[0049] Furthermore, the material changing mechanism also includes a lifting block 9 for driving the blocking roller 5 on the unloading platform 2 away from the limit. The lifting blocks 9 are fixedly installed on the outside of the first material changing plate 11 and the second material changing plate 28 by the fixing column 10, and the lifting blocks 9 on the first material changing plate 11 and the second material changing plate 28 are symmetrically arranged.

[0050] Preferably, in this embodiment, during the sequential unloading and synchronous material changing operations, the output shaft of the motor 22 drives the worm gear 21 to rotate. Under the meshing connection between the worm gear 21 and the worm wheel 20, the second connecting shaft 19 is driven to rotate. Under the synchronous driving action of the second synchronous chain 18, the second connecting shaft 19 drives the first connecting shaft 15 to rotate. Under the synchronous driving action of the first synchronous chain 17, the first connecting shaft 15 drives the first turntable 14 to rotate on the first material changing plate 11. Thus, under the rotational connection of the two first turntables 14, the first material changing plate 11 is driven to perform an oscillating circular rotation operation.

[0051] Correspondingly and synchronously, as the second connecting shaft 19 rotates, the third connecting shaft 25 is driven to rotate under the synchronous driving action of the third synchronous chain 24, thereby driving the second turntable 26 to rotate on the second material changing plate 28. Then, under the synchronous traction action of the fourth synchronous chain 29, the two second turntables 26 are driven to drive the second material changing plate 28 to perform oscillating circular rotation operation, and perform synchronous circular rotation operation with the first material changing plate 11 on one side. Thus, the first discharge trough 12 on the first material changing plate 11 and the second material changing plate 28 can respectively realize the receiving of glass test tubes 4, and the switching and docking of glass test tubes 4 at the next second discharge trough 32 position, so that the glass test tubes 4 that are discharged are progressively switched on the second discharge trough 32.

[0052] Furthermore, whenever the lifting block 9 on the first material changing plate 11 and the second material changing plate 28 moves to the position below the lifting block 6 and rotates upward, the lifting block 6 drives the barrier roller 5 to compress the spring 8 and lift it upward, thereby allowing the glass test tube 4 on one side of the barrier roller 5 to be unloaded individually. The unloaded glass test tube 4 can then fall onto the material release seat 30 closest to the unloading platform 2 under the guidance of the guide plate 31, thus continuously realizing the unloading and progressive material changing of the glass test tube 4, better realizing the annealing operation of the glass test tube 4 in the annealing furnace 3, and significantly improving the annealing efficiency.

[0053] It should be noted that the first synchronous chain 17, the second synchronous chain 18, the third synchronous chain 24 and the fourth synchronous chain 29 all include, but are not limited to, synchronous sprockets and synchronous belt structures, and can be selected according to processing requirements.

[0054] By using this method of feeding glass test tubes 4 one by one, the integrity of the feeding process can be well guaranteed, the compressive stress on the glass test tubes 4 during the feeding process can be reduced, the surface smoothness and structural integrity of the glass test tubes 4 can be effectively protected, the defect rate of the feeding process can be significantly reduced, the cost of manual intervention can be reduced, and the operational safety can be improved. Furthermore, through the set-up one-by-one material changing mechanism, targeted processing can be completed at each station in a progressive switching manner. Compared with the traditional single furnace overall annealing mode, it can better eliminate the residual stress inside the test tubes, realize continuous production operations, and significantly improve the annealing efficiency. Through the synergistic effect of the two, not only are the problems of low efficiency, high dependence on manual labor, and high energy consumption in the traditional glass test tube annealing process well solved, but also promote the transformation of glass test tube continuous production.

[0055] Example 3

[0056] like Figures 1-12As shown, this embodiment, based on the above embodiment, also includes an annealing rotation mechanism, which is installed on the annealing furnace 3 and driven by a sequential material changing mechanism. It is used to drive the glass test tubes 4 on the second feeding trough 32 to perform rotational annealing. The annealing rotation mechanism includes a drive wheel 33 for driving the glass test tubes 4 on the second feeding trough 32 to rotate. The drive wheel 33 is symmetrically rotated and installed on the second feeding trough 32. The drive wheel 33 is driven to rotate by the movement of the first material changing plate 11.

[0057] Furthermore, the annealing rotation mechanism also includes a fourth connecting shaft 36 for driving the drive wheel 33 to rotate. The drive wheel 33 is rotatably connected to the second discharge trough 32 via the drive shaft 34. The drive shaft 34 is rotatably connected to the fourth connecting shaft 36 via the fifth synchronous chain 35. The fourth connecting shaft 36 is rotatably connected to the discharge seat 30.

[0058] Furthermore, the annealing rotation mechanism also includes a gear ring 38 for driving the fourth connecting shaft 36 to rotate. The gear ring 38 is equidistantly installed on the inner wall of the first material changing plate 11. The inner side of the gear ring 38 is provided with a plurality of drive teeth 39 that mesh with the rotating gear 37. The rotating gear 37 is fixedly connected to one end of the fourth connecting shaft 36.

[0059] Furthermore, a material feeding plate 40 for guiding material is provided on one side of the feeding seat 30. The material feeding plate 40 is fixedly installed on the base plate 1 by a support seat 41. A clearance groove 42 for avoiding the first material changing plate 11 and the second material changing plate 28 is provided on the material feeding plate 40.

[0060] Furthermore, a receiving box 43 is provided on one side of the material feeding plate 40. The receiving box 43 is fixedly connected to the piston rod of the lifting push rod 44, which is fixedly installed on the base plate 1.

[0061] Preferably, in this embodiment, whenever the glass test tube 4 on the second discharge trough 32 completes a progressive station switching operation, the gear ring 38 on the first material changing plate 11 rotates from the toothless area to the toothed drive tooth 39. This, in turn, drives the fourth connecting shaft 36 to rotate under the meshing connection between the drive tooth 39 on the gear ring 38 and the rotating gear 37. The fourth connecting shaft 36, under the synchronous traction of the fifth synchronous chain 35, drives the drive wheel 33 on the drive shaft 34 to rotate, thereby realizing the rotation operation of the glass test tube 4 on the second discharge trough 32. That is, whenever a progressive station switching operation is performed... During operation, the glass test tube 4 immediately stops rotating to prevent the material from slipping off the first material receiving trough 12 on the first material receiving plate 11 and the second material receiving plate 28. This protects the glass test tube 4 during the progressive switching of work positions. When the first material receiving trough 12 finishes receiving the material and rotates downward, the drive wheel 33 can drive the glass test tube 4 to rotate accordingly, further improving the uniformity of the annealing process of the glass test tube 4 and significantly improving the annealing efficiency of the glass test tube 4. After annealing, the glass test tube 4 can be collected at the receiving box 43 through the unloading plate 40.

[0062] It should be noted that the fifth synchronous chain 35 includes, but is not limited to, synchronous sprockets and synchronous belt structures, and can be selected according to processing requirements.

[0063] By employing a rotating annealing mechanism that coordinates progressive station switching with rotation, the glass test tube 4 can rotate at a uniform speed at each annealing station. This synergistic effect further enhances the annealing result. Secondly, the molecular motion inside the glass test tube 4 becomes more balanced during rotation, which helps to accelerate the release and dissipation of residual stress. Furthermore, the combination of rotational annealing and progressive station switching further improves the consistency of annealing quality across batches, avoiding performance fluctuations caused by differences in static placement posture. Finally, the automated rotation drive and station switching work together without the need for manual intervention to adjust the test tube posture, further improving the automation and stability of the production process, reducing the uncertainty risks associated with manual operation, and further enhancing the annealing efficiency of the glass test tube 4.

[0064] It should be noted that the components in this application are all general standard parts or parts known to those skilled in the art, which effectively solve the technical problems raised in the background art.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
