Description

Technical Field

[0001] This utility model relates to the field of ceramic roller processing technology, and in particular to a microwave drying device for ceramic roller blanks. Background Technology

[0002] The straightness and roundness of the ceramic roller blank before high-temperature sintering are crucial to the straightness and roundness of the finished ceramic roller, requiring drying treatment before high-temperature sintering. Currently, most ceramic roller blank drying operations mainly employ horizontal static drying methods combined with external heating methods, primarily using flame, hot air, electric heating, and steam drying. These methods utilize heat conduction theory to transfer heat from the outside of the heated object to the inside of the ceramic roller blank, gradually increasing the center temperature and causing the moisture to gradually evaporate to the process control level.

[0003] However, because the outer surface of the ceramic roller blank is always in contact with the surface of the carrier container during horizontal static drying, there is a problem that some parts of the contact surface of the ceramic roller blank are not dried thoroughly. This results in uneven moisture content inside the dried ceramic roller blank, affecting the straightness and roundness of the ceramic roller before high-temperature sintering. Utility Model Content

The first drive wheel and the plurality of first driven wheels are evenly arranged between the inlet and the outlet. The first drive wheel and the plurality of first driven wheels are all meshed with the inner surface of the first transmission chain. One end of the support roller is rotatably connected to one of the first transmission chains, and the other end of the support roller is rotatably connected to another of the first transmission chains.

[0013] The housing is equipped with a first driving component, which is rotatably connected to two adjacent first drive wheels via an output shaft.

[0014] As an improvement to the above solution, the second conveyor chain assembly includes a second transmission chain, the rotating component is a gear, the second transmission chain has a plurality of meshing holes, and the external teeth of the gear mesh with the meshing holes.

[0016] The heating chamber is provided with a second driving member, which is rotatably connected to the second drive wheel.

[0017] As an improvement to the above solution, the rotating component is fixedly disposed at one end of the supporting roller, and a first bearing is disposed on one side of the first transmission chain facing the supporting roller, and the rotating component is rotatably connected to the first bearing.

[0018] A second bearing is provided on the side of the other first transmission chain facing the support roller, and the inner ring of the support roller is rotatably connected to the second bearing.

[0019] As an improvement to the above solution, the second conveyor chain assembly further includes at least two tensioning rollers, which are located above the second driving roller and the second driven roller, and at least two of the tensioning rollers are located on the same horizontal plane.

[0020] As an improvement to the above solution, the microwave drying assembly includes multiple microwave sources, the housings of the microwave sources are fixed to the top of the box, and the microwave generating surfaces of the microwave sources face the heating cavity.

[0021] The microwave intensity of the plurality of microwave sources gradually increases along a predetermined direction, the predetermined direction being the direction from the inlet to the outlet.

At the same time, the outer surface of the ceramic roller blank will not continuously contact the bearing surface of the supporting roller, avoiding the problem of localized incomplete drying at the contact surface, and effectively ensuring the uniform distribution of moisture within the ceramic roller blank.

[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0039] The microwave drying equipment for ceramic roller blanks of this invention can effectively ensure the straightness and roundness of the ceramic rollers during the drying process, while ensuring the uniform distribution of moisture within the ceramic roller blank 7.

[0040] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the microwave drying equipment for ceramic roller blanks includes a housing 1, a microwave drying assembly 2, a first conveyor chain assembly 3, and a second conveyor chain assembly 4. A heating chamber 11 is formed inside the housing 1, and the microwave drying assembly 2 is disposed on top of the heating chamber 11.

[0041] The first conveyor chain assembly 3 is disposed in the heating chamber 11. The housing 1 is provided with an inlet 12 and an outlet 13. The first conveyor chain assembly 3 reciprocates between the inlet 12 and the outlet 13. The first conveyor chain assembly 3 is rotatably connected to a plurality of support rollers 301, which are used to support the ceramic roller blank 7. The first conveyor chain assembly 3 can then convey the ceramic roller blank 7 from the inlet 12 to the outlet 13 so that the ceramic roller blank 7 can enter the heating chamber 11 for drying.

[0042] The first conveyor chain assembly 3 is rotatably connected to a plurality of rotating parts 302, and each rotating part 302 is fixedly connected to one of the supporting rollers 301; the second conveyor chain assembly 4 is disposed in the heating chamber 11, and each rotating part 302 is engaged with the outer surface of the second conveyor chain assembly 4.

[0043] According to the microwave drying equipment for ceramic roller blanks in this embodiment, when drying the ceramic roller blank 7, the ceramic roller blank 7 can be placed on the support roller 301 of the first conveyor chain assembly 3, and the ceramic roller blank 7 can be conveyed to the heating chamber 11 by the first conveyor chain assembly 3. Then, microwaves are provided to the heating chamber 11 by the microwave drying assembly 2, and the ceramic roller blank 7 is heated and dried simultaneously inside and outside by microwave drying to remove excess moisture inside the ceramic roller blank 7.

[0044] Meanwhile, the second conveyor chain assembly 4 is engaged with multiple rotating parts 302 on its outer surface. When the first double chain assembly moves back and forth between the inlet 12 and the outlet 13, the rotating parts 302 can rotate relative to the second conveyor chain assembly 4, which in turn drives the support roller 301 to rotate relative to the first conveyor chain assembly 3. When the support roller 301 rotates, it will indirectly drive the ceramic roller blank 7 to rotate.

[0045] This allows the ceramic roller blank 7 to maintain rotational motion as it moves from the inlet 12 to the outlet 13, effectively ensuring the straightness and roundness of the ceramic roller during the drying process. At the same time, the outer surface of the ceramic roller blank 7 will not continuously contact the bearing surface of the supporting roller 301, avoiding the problem of localized incomplete drying at the contact surface, and effectively ensuring the uniform distribution of moisture within the ceramic roller blank 7.

[0046] It should be noted that the outer wall of the housing 1 is made of stainless steel to effectively prevent microwave leakage in the heating cavity 11 and improve the energy utilization rate of the microwave drying assembly 2.

[0047] It should also be noted that the interior of the heating chamber 11 has a tunnel-like appearance to control the temperature above and below the first conveyor chain assembly 3, thereby improving the heating efficiency of the ceramic roller blank 7 inside the heating chamber 11.

[0048] Among them, such as Figures 2 to 4As shown, at least two sets of first conveyor chain assemblies 3 are horizontally arranged in the heating chamber 11, so as to use the two sets of first conveyor chain assemblies 3 to connect the support roller 301, thereby improving the stability of the first conveyor chain assembly 3 driving the support roller 301 to move.

[0049] Specifically, such as Figures 4 to 6 As shown, the first conveyor chain assembly 3 includes a first driving wheel 31, a first transmission chain 32, and several first driven wheels 33. The first driving wheel 31 and several first driven wheels 33 are evenly arranged between the inlet 12 and the outlet 13. The first driving wheel 31 and several first driven wheels 33 are all meshed with the inner surface of the first transmission chain 32. One end of the support roller 301 is rotatably connected to one of the first transmission chains 32, and the other end of the support roller 301 is rotatably connected to another first transmission chain 32. A first driving member 34 is provided inside the housing 1. The first driving member 34 is rotatably connected to two adjacent first driving wheels 31 through an output shaft.

[0050] Furthermore, when the ceramic roller blank 7 is placed above the support roller 301, the first driving member 34 drives two adjacent first driving wheels 31 to rotate synchronously, which in turn drives two adjacent first transmission chains 32 to reciprocate synchronously between the inlet 12 and the outlet 13, so as to move the ceramic roller towards the outlet 13 and discharge it from the outlet 13 after drying. Several second driven wheels 43 can rotate synchronously under the drive of the first transmission chain 32 to improve the stability of the reciprocating movement of the first transmission chain 32.

[0051] It should be noted that both the first driving wheel 31 and the first driven wheel 33 are sprockets, and the inner surface of the first transmission chain 32 has multiple meshing holes 411, through which the sprockets mesh and connect with the inner surface of the first transmission chain 32.

[0052] Specifically, such as Figure 4 , Figure 5 and Figure 8 As shown, the second conveyor chain assembly includes a second transmission chain 41, and the rotating component 302 is a gear. The second transmission chain 41 has multiple meshing holes 411, and the external teeth of the gear mesh with the meshing holes 411. As the support roller 301 moves from the inlet 12 to the outlet 13 following the first conveyor chain assembly, the external teeth of the gear mesh with the meshing holes 411 of the second transmission chain 41, allowing the gear to rotate relative to the second transmission chain 41 above it. This, in turn, drives the support roller 301 to rotate relative to the first transmission chain 32, indirectly driving the ceramic roller blank 7 to rotate.

[0053] Furthermore, by engaging the external teeth of the gear with the meshing hole 411, the contact area between the gear and the second transmission chain 41 can be increased, avoiding slippage that could affect the rotation of the gear and the support roller 301, thereby further ensuring that the support roller 301 can rotate relative to the ceramic roller blank 7.

[0054] More specifically, to further improve the transmission efficiency between the support roller 301 and the ceramic roller blank 7, such as Figure 5 and Figure 8 As shown, the second conveyor chain assembly also includes a second driving wheel 42 and a second driven wheel 43. The second driving wheel 42 and the second driven wheel 43 are evenly arranged between the inlet 12 and the outlet 13. The second transmission chain 41 is meshed with the second driving wheel 42 and the second driven wheel 43. The heating chamber 11 is provided with a second driving member 44, which is rotatably connected to the second driving wheel 42.

[0055] Furthermore, as the support roller 301 moves from the inlet 12 to the outlet 13 following the first conveyor chain assembly, the second drive member 44 can drive the second drive wheel 42 to rotate, causing the second transmission chain 41 to reciprocate between the inlet 12 and the outlet 13, thereby increasing the meshing speed between the second transmission chain 41 and the gear, effectively increasing the rotational speed of the gear and the support roller 301, accelerating the rotational speed of the ceramic roller, and further ensuring the straightness and roundness of the ceramic roller when the support roller 301 conveys the ceramic roller.

[0056] In an optional embodiment, when the first conveyor chain assembly 3 drives the ceramic roller to move into the heating chamber 11, the second drive member 44 can be paused. When the first transmission chain 32 moves from the inlet 12 to the outlet 13, the gear meshes with the stationary second transmission chain 41. Under the action of the first transmission chain 32, the gear rolls relative to the second transmission chain 41, realizing the rotational motion of the gear itself, which correspondingly drives the support roller 301 to rotate, so that the ceramic roller blank 7 can maintain rotational motion while moving from the inlet 12 to the outlet 13.

[0057] In another optional embodiment, when the first conveyor chain assembly 3 drives the ceramic roller to move into the heating chamber 11, the second drive member 44 can also be driven to accelerate the rotation speed of the gear and the support roller 301 by using the gear to mesh with the moving second transmission chain 41, thereby correspondingly accelerating the rotation speed of the ceramic roller.

[0058] It should be noted that if the ceramic roller blank 7 needs to stay in the heating chamber 11 for a certain period of time, the first drive component 34 can be paused after the ceramic roller blank 7 is fully arranged above the support roller 301, so that the forward movement of the first transmission chain 32 stops, allowing the ceramic roller blank 7 to stay in the heating chamber 11. During this process, the second drive component 44 can be kept running, so that the support roller 301 continues to rotate under the cooperation of the second drive component 44, the second transmission chain 41, and the gear, indirectly driving the ceramic roller blank 7 to rotate. This ensures that the ceramic roller blank 7 continues to rotate while staying inside the heating chamber 11, and further ensures that the outer surface of the ceramic roller blank 7 does not continuously contact the bearing surface of the support roller 301, avoiding the problem of localized incomplete drying at the contact surface when the ceramic roller blank 7 stays in the heating chamber 11, which would affect the drying efficiency.

[0059] In this embodiment, as Figure 7 As shown, the rotating component 302 is fixedly mounted on one end of the supporting roller 301. A first bearing 321 is provided on one side of the first transmission chain 32 facing the supporting roller 301, and the rotating component 302 is rotatably connected to the first bearing 321. A second bearing 322 is provided on the other side of the first transmission chain 32 facing the supporting roller 301, and the inner ring of the supporting roller 301 is rotatably connected to the second bearing 322. The first bearing 321 is used to improve the stability of the rotating component 302 during rotation, and the second bearing 322 is used to improve the stability of the supporting roller 301 during rotation. This allows the supporting roller 301 and the rotating component 302 to rotate smoothly relative to the first transmission chain 32, reducing friction between the supporting roller 301, the rotating component 302, and the first transmission chain 32, and improving operating efficiency.

[0060] The first bearing 321 and the second bearing 322 are mounted on the side of the first transmission chain 32 via a connecting rod. The outer diameter of the first bearing 321 is smaller than that of the second bearing 322 to ensure that the outer diameter of the rotating part 302 can be close to or equal to the outer diameter of the drum, thereby improving the structural compactness of the connection between the rotating part 302 and the drum.

[0061] More specifically, such as Figure 5 and Figure 8As shown, the second conveyor chain assembly 4 also includes at least two tensioning wheels 45. The tensioning wheels 45 are located above the second driving wheel 42 and the second driven wheel 43, and the at least two tensioning wheels 45 are located on the same horizontal plane. The tensioning effect of the tensioning wheels 45 on the second conveyor chain ensures that the second conveyor chain can remain horizontally straight during transmission and is not affected by its own weight or external forces, thus ensuring the meshing effect between the second conveyor chain and the gear. This ensures that the gear and the support roller can complete the rotation action when the first conveyor chain assembly 3 and the second conveyor chain assembly 4 are in transmission, and further prevents the outer surface of the ceramic roller blank 7 from constantly contacting the bearing surface of the support roller 301.

[0062] In addition, it should be noted that, as Figure 2 and Figure 3 As shown, to ensure the installation stability of the first conveyor chain assembly 3 and the second conveyor chain assembly 4, a mounting bracket 14 is arranged in the heating chamber 11. The first driving member 34, the first driving wheel 31, the second driven wheel 43, the second driving member 44, the second driving wheel 42, the second driven wheel 43 and the tensioning wheel 45 are all connected to the mounting bracket 14 through the bearing seat 15.

[0063] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the microwave drying assembly 2 includes multiple microwave sources 21. The housing of the microwave source 21 is fixed to the top of the box 1, and the microwave generating surface of the microwave source 21 faces the heating cavity 11, so as to provide microwaves into the heating cavity 11 by means of the microwave generating surface of the microwave source 21. The microwaves cause the molecules inside the ceramic roller blank 7 to rub against each other and generate shock wave heat energy, so as to achieve simultaneous heating of the inside and outside of the ceramic roller blank 7, and quickly remove excess moisture; at the same time, it eliminates the thermal stress caused by uneven heating, and eliminates the hidden danger of the ceramic roller blank 7 not meeting the straightness and roundness standards after sintering.

[0064] The microwave intensity of multiple microwave sources 21 gradually increases along a predetermined direction, which is from the inlet 12 to the outlet 13. That is, the microwave intensity distribution of multiple microwave sources 21 follows the principle of increasing from weak to strong along the predetermined direction, thereby realizing the drying interval process of decreasing moisture in the ceramic roller blank, so as to maximize the energy utilization rate of microwave sources 21.

[0065] In this embodiment, as Figure 1As shown, a diameter detection element 22 is provided on the top surface of the housing 1. The diameter detection element 22 is located between the microwave source 21 and the discharge port 13. The diameter detection element 22 is used to detect the diameter of the dried ceramic roller blank 7 in order to determine whether the straightness and roundness of the dried ceramic roller blank 7 meet the production requirements. Preferably, the diameter detection element 22 is a laser diameter gauge. The laser diameter gauge realizes non-contact, non-destructive and real-time diameter measurement. After drying, multiple sets of outer diameter values ​​of the ceramic roller blank 7 can be obtained, and the straightness and roundness of the dried ceramic roller blank 7 can be determined accordingly.

[0066] Furthermore, a laser marking machine 23 is arranged between the microwave source 21 and the discharge port 13. The laser marking machine 23 forms permanent and high-precision marks on the outer surface of the dried ceramic roller blank 7 with a high-energy laser beam to facilitate quality management of the ceramic roller blank.

[0067] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the microwave drying equipment for ceramic roller blanks also includes a feeding robot 51 and a discharging robot 52. The feeding robot 51 is close to the inlet 12, and the discharging robot 52 is close to the outlet 13. The feeding robot 51 is used to place the undried ceramic roller blank 7 from the inlet 12 onto the support roller 301, and the discharging robot 52 is used to remove the dried ceramic roller blank 7 from the outlet 13, thereby realizing intelligent feeding and discharging of the microwave drying equipment for ceramic roller blanks.

[0068] In embodiments of this utility model, such as Figure 1 As shown, the microwave drying equipment for ceramic roller blanks also includes a condenser 6, which has a condensation section. A condensation port is formed on the top of the housing 1. The condensation section extends into the heating chamber 11 through the condensation port so as to condense the water vapor generated during the microwave drying process, liquefy the water vapor in time, collect and centrally process it, effectively avoid the excessive humidity in the heating chamber 11 of the housing 1, which would affect the uniformity of moisture inside the dried ceramic roller blank 7, and achieve the purpose of recycling water resources.

[0069] Therefore, by combining the above embodiments and implementing this utility model, the following beneficial effects are achieved:

[0070] (1) Microwave drying is used to heat the inside and outside of the ceramic roller blank 7 simultaneously, which can quickly remove excess moisture and eliminate the thermal stress caused by uneven heating, thus eliminating the hidden danger of the straightness and roundness of the ceramic roller blank 7 not meeting the standards after sintering.

[0071] (2) By cooperating with the first conveyor chain assembly 3 and the second conveyor chain assembly 4, the ceramic roller blank 7 can maintain its own rotational motion while moving forward in the heating chamber 11, which effectively ensures the straightness and roundness of the ceramic roller during the drying process, and avoids the problem of local incomplete drying at the contact surface, and effectively ensures the uniform distribution of moisture in the ceramic roller blank 7.

[0072] (3) The microwave intensity distribution in the heating cavity 11 follows the principle of increasing from weak to strong along a predetermined direction, thereby realizing the drying process of decreasing moisture in the ceramic roller blank, so as to maximize the energy utilization of the microwave source 21.

[0073] (4) It can achieve non-contact, non-destructive and real-time diameter measurement. After drying, multiple sets of outer diameter values ​​of ceramic roller blank 7 can be measured and obtained, and the straightness and roundness of the dried ceramic roller blank 7 can be judged accordingly to meet the production requirements.

[0074] (5) It can condense the water vapor generated during microwave drying, liquefy the water vapor in time and collect and process it in a centralized manner, effectively avoiding excessive humidity in the heating chamber 11 of the box 1, which would affect the uniformity of moisture inside the ceramic roller blank 7 after drying.

[0075] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications are also considered to be within the protection scope of this utility model.
