Description

Technical Field

[0001] The invention relates to the technical field of sintering kilns, in particular to a roller rod mounting structure for a quick-change roller furnace with integrated automatic detection. Background Art

[0002] A roller hearth furnace is a continuous heat treatment furnace primarily composed of a roller table, a furnace body, and a heating system. Workpieces are placed on the roller table, and the rotation of the roller table automatically conveys the material. Roller hearth furnaces offer the distinct advantages of continuous production, uniform heating, high production efficiency, and stable product quality. They are widely used in industries such as metallurgy, ceramics, and glass for sintering and annealing processes, playing a crucial role in improving product performance.

[0003] The roller hearth furnace houses multiple sets of parallel rollers. Their primary function is to support and convey the incoming material. However, due to the high temperatures encountered in roller hearth furnaces, the rollers are prone to cracking and deformation after prolonged use, making it difficult to convey material reliably. Damaged rollers must be promptly replaced. In most cases, roller hearth furnace rollers are connected to the furnace body via connectors such as bearings and bearing seats. However, replacing a roller requires disassembling these connectors, making the process cumbersome. Furthermore, due to the varying processing temperatures of different materials, the rollers can experience thermal deformation during operation, particularly changes in length. If bearings are used for connection, the deformation forces generated by the rollers are directly transmitted to the bearings, which can easily lead to uneven force distribution and uneven wear. More seriously, this can cause the rollers to bend, preventing the roller hearth furnace from properly conveying material. Summary of the Invention

[0020] A pulling plate is slidably connected to the inner link plate, and two sets of hinged rods are rotatably mounted on the pulling plate, and one end of the hinged rod away from the pulling plate is rotatably connected to the clamping member;

[0021] An energy storage kit is arranged on the pulling plate. A connecting convex shaft is provided on the energy storage kit. The convex shaft is in rolling cooperation with the retardation groove arranged on the inner link plate.

[0022] As a further solution of the present invention: the energy storage kit includes two sets of slide grooves provided on the pulling plate, wherein a slider is slidably installed in the slide groove, one end of the slider is connected to the convex shaft, and the other end is connected to the protruding plate;

[0023] The energy storage kit further includes a transverse shaft slidably connected to the protruding plate. A second cylindrical spring is sleeved on the transverse shaft. Both ends of the second cylindrical spring are respectively connected to the protruding plate.

[0028] The elastic preload component ensures that the end of the roller away from the connector always maintains a stable and reliable contact with the connector seat, effectively preventing the roller from accidentally sliding off the connector seat and preventing the material in the furnace from falling and being damaged due to unstable support. Secondly, when the roller expands due to heat, the elastic preload component effectively cushions the expansion deformation of the roller, avoiding bending deformation caused by the rigid connection at both ends of the roller due to thermal expansion.

[0029] By setting up the pulling component, the difficulty of operation is significantly reduced in the initial installation stage, the problem of accidental closing is avoided, and the efficiency and safety of installation are improved. After the installation is completed, the roller is firmly locked, which effectively prevents loosening or falling off, and ensures the reliable operation of the equipment. In the face of the thermal expansion of the roller, an effective buffer is formed to avoid the risk of structural damage caused by expansion, and ensure the stability and durability of the equipment under temperature changes. At the same time, after cooling, the first column spring and the second column spring have a synergistic effect to reset the roller, further maintaining the stable installation state of the roller, reducing the failure and maintenance costs caused by thermal expansion and contraction, and improving production efficiency and overall equipment performance.

When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0044] See also Figures 1 to 10 In an embodiment of the present invention, a roller rod mounting structure for a quick-change roller furnace with integrated automatic detection includes a furnace body 1, a drive rod 4, a seal 11, an elastic preload assembly, and a pulling assembly.

[0045] The furnace body 1 is provided with a mounting hole 101 for the roller rod 24 to pass through;

[0046] The driving rod 4 is provided on the furnace body 1, and one end of the driving rod 4 is connected to a connector 12, which cooperates with a connecting seat 25 installed on the furnace body 1 to support both ends of the roller 24, wherein the end of the connecting head 12 away from the connecting seat 25 is further connected to a bearing 5, and the bearing 5 abuts against a supporting platform 13 provided on the furnace body 1;

[0047] Specifically, the furnace body 1 is further provided with a motor 2, and the output shaft of the motor 2 is connected to a plurality of helical gear sets 3, and the helical gear sets 3 are connected to the driving rod 4;

[0048] Furthermore, the interior of the connecting head 12 and the connecting seat 25 is a hollow structure, and the diameter of the hollow structure is the same as the outer diameter of the circumference of the roller rod 24;

[0049] An inner conical surface 2501 is provided at one end of the connecting seat 25 facing the connecting head 12 , and the inner conical surface 2501 can guide the roller 24 to enter the interior of the connecting seat 25 .

[0050] The helical gear set 3 is formed by two groups of helical gears, one group of which is connected to the output shaft of the motor 2, and the other group of helical gears is connected to the horizontal plate 26 set on the furnace body 1 through a mounting plate (not shown in the figure). The helical gears are rotatably connected to the mounting plate, and a connecting groove 301 is provided on the rotating shaft of the helical gear, and the connecting groove 301 is slidably adapted to the connecting shaft 401 set on the driving rod 4.

[0051] Among them, a torque sensor (not shown in the figure) is also provided on the helical gear connected to the driving rod 4. When the roller 24 is bent, deformed, or cracked, the resistance to conveying materials will increase. The torque value applied to the roller 24 can be detected by the torque sensor. When the torque value exceeds the preset value, an alarm is issued to remind the staff to replace it in time.

[0052] In the present application, a plurality of groups of parallel and equidistantly arranged rollers 24 are provided inside the furnace body 1. Each group of rollers 24 is connected to the output shaft of the motor 2 via the connector 12 and the helical gear set 3. This enables the output shaft of the motor 2 to stably drive each roller 24 to rotate when the motor 2 is working, thereby realizing smooth transportation of materials entering the furnace body 1, greatly improving the efficiency and stability of material transportation, and ensuring the continuity of the entire production process.

[0053] When installing the roller 24, the operation is convenient and accurate. First, one end of the roller 24 is firmly connected to the connecting head 12 with bolts. The bolt connection method not only ensures the reliability of the connection, but also facilitates subsequent disassembly and maintenance. Then, the end of the roller 24 away from the connecting head 12 is inserted into the corresponding installation hole 101. When the roller 24 extends to the position of the connecting seat 25, the inner conical surface 2501 on the connecting seat 25 can accurately guide the end of the roller 24 to achieve coaxiality with the connecting seat 25. On the one hand, this design greatly improves the portability of the connection between the roller 24 and the connecting seat 25, and effectively reduces the manpower, material resources and time required in the process of installing the roller 24. On the other hand, since the inner conical surface 2501 can accurately guide the end of the roller 24 to be coaxial with the connecting seat 25, the roller 24 can always rotate stably along its central axis during rotation, avoiding the phenomenon of the roller 24 jumping during rotation, thereby achieving stable and uniform transportation of materials, ensuring the uniform heating of the materials in the furnace body 1, improving product quality, and reducing the risk of equipment wear and failure caused by the jumping of the roller 24, thereby extending the service life of the equipment and providing a solid and reliable guarantee for the entire production process.

[0054] The output shaft of the motor 2 is connected to the connector 12 by a helical gear set 3, so that during the disassembly of the connector 12 and the roller 24, one set of helical gears can be rotated out relative to the other set of helical gears, avoiding the difficulty of disassembly due to mutual interference between the two sets of helical gears.

[0055] See also Figure 8 The seal 11 is coaxially rotatably connected to the drive rod 4, and the seal 11 has the same diameter as the mounting hole 101, wherein a second conical surface 1101 is formed on one end of the seal 11 facing the connecting seat 25. When the seal 11 is inserted into the mounting hole 101, the presence of the second conical surface 1101 makes it more convenient.

[0056] When one end of the roller rod 24 smoothly enters the connecting seat 25 under the guidance of the inner conical surface 2501, the second conical surface 1101 can also effectively guide the seal 11 to safely enter the installation hole 101. At this time, the seal 11 can reliably seal the annular gap formed between the driving rod 4 and the installation hole 101, thereby preventing the heat in the furnace body 1 from escaping from the annular gap, preventing high temperature from escaping from the furnace to the outside of the equipment, and eliminating the possible high temperature damage to the outside of the equipment.

[0057] See also Figures 5 to 7The elastic pre-tightening component is provided on the driving rod 4, and the two sets of clamping members 14 mounted on the furnace body 1 cooperate with the elastic pre-tightening component to enable the driving rod 4 to have a tendency to move toward the connecting seat 25;

[0058] The elastic preload assembly includes a support member 6 coaxially connected to the drive rod 4 and an abutment member 10 slidably sleeved on the drive rod 4. The abutment member 10 is connected to the support member 6 via a first cylindrical spring 8. A first conical surface 1001 is formed on one end of the abutment member 10 away from the first cylindrical spring 8. The first conical surface 1001 abuts and fits with the clamping member 14. When the two sets of the clamping members 14 are closed, they can act on the first conical surface 1001 to compress the first cylindrical spring 8.

[0059] The elastic preload assembly further includes a telescopic limiter kit connected between the support member 6 and the abutment member 10, the telescopic limiter kit being capable of axially locking the support member 6 and the abutment member 10, the telescopic limiter kit including a connecting tube 7 coaxially fixedly connected to the support member 6 and a telescopic tube 9 coaxially fixedly connected to the abutment member 10, the connecting tube 7 being slidably fitted over the telescopic tube 9;

[0060] A limiting groove 701 is formed on the inner wall of the connecting tube 7 , and a limiting bar 901 is formed on the outer wall of the telescopic tube 9 . The limiting groove 701 is slidably connected to the limiting bar 901 .

[0061] In the initial state, the pulling assembly can make the two groups of clamping members 14 in an open state, so that the driving rod 4, the connecting head 12 and the roller rod 24 can be smoothly placed into the installation hole 101. Then, the pulling assembly is controlled to move in the opposite direction, causing the two groups of clamping members 14 to move in opposite directions and close. During the closing process, the clamping members 14 act on the first conical surface 1001 from both sides to make the abutment 10 evenly stressed, and under the coordinated action of the clamping members 14 and the first conical surface 1001, the abutment 10 is pushed toward the connecting head 12, thereby compressing the first columnar spring 8. At this time, the elastic force of the first columnar spring 8 acts in the opposite direction on the support member 6, giving the support member 6 the force to drive the driving rod 4 and the connecting head 12 toward the connecting seat 25.

[0062] Based on the above settings, firstly, it ensures that the end of the roller 24 away from the connecting head 12 always maintains a stable and reliable abutment with the connecting seat 25, effectively preventing the roller 24 and the connecting seat 25 from accidentally slipping, preventing the material in the furnace body 1 from falling and being damaged due to unstable support, and ensuring the stability and safety of material transportation; secondly, when the roller 24 expands due to heat and its length increases, its deformation force along the length direction is directly transmitted to the connecting head 12, driving the connecting head 12 to move away from the connecting seat 25. During this process, the first cylindrical spring 8 is further compressed, effectively buffering the expansion deformation of the roller 24. This buffering mechanism avoids the bending deformation of the two ends of the roller 24 due to the rigid connection when it expands due to heat, thereby ensuring that the roller 24 can still maintain structural integrity and working performance in a high temperature environment, extending the service life of the roller 24, reducing equipment maintenance and downtime caused by damage to the roller 24, further improving the reliability and stability of the entire equipment operation, and providing a strong guarantee for continuous and stable production.

[0063] It should be noted that when the abutment 10 is clamped by the clamping member 14, it will produce movement along the length direction of the driving rod 4. At this time, the first columnar spring 8 can be compressed. At the same time, as the abutment 10 moves, the same sliding will occur between the connecting tube 7 and the telescopic tube 9. Since the connecting tube 7 and the telescopic tube 9 are connected by the limiting groove 701 and the limiting bar 901, the distance between the abutment 10 and the support member 6 can be changed and the synchronous rotation of the two can be guaranteed. This setting effectively avoids relative rotation between the abutment 10 and the support member 6, so that the first columnar spring 8 will not be twisted due to external force, resulting in changes in its stored elastic force, so that in a stable state, the first columnar spring 8 can provide a more stable and reliable elastic force.

[0064] It should also be noted that when the roller rod 24 undergoes thermal deformation, the positions of the connecting head 12 and the driving rod 4 will change. At this time, the connecting shaft 401 on the driving rod 4 can move relative to the connecting groove 301, but the connecting shaft 401 can still remain inside the connecting groove 301, thereby achieving stable power transmission.

[0065] Furthermore, when the roller 24 is thermally deformed, the position of the seal 11 will also change, but the seal 11 has a movable length. When it moves, it can ensure the sealing effect of the annular gap, thereby preventing heat from escaping from the furnace body 1.

[0066] See also Figure 5 、 Figures 9 and 10 The pulling assembly is arranged on the furnace body 1 and connected to the clamping member 14, and the pulling assembly can drive the two groups of the clamping members 14 to open or close;

[0067] The pulling assembly includes an inner plate 22, a pulling plate 16 and an energy storage kit.

[0068] The inner link plate 22 is fixedly mounted on the furnace body 1. The inner link plate 22 is provided with a stagnation groove. The stagnation groove includes two groups of inclined grooves 2202 provided on the inner link plate 22. A concave protrusion is formed at the connection between the two groups of inclined grooves 2202.

[0069] The pulling plate 16 is provided with a pull ring 21, and the pulling plate 16 is slidably connected to the inner link plate 22. Specifically, a guide block 23 is fixedly installed on the pulling plate 16, and the guide block 23 is slidably connected to a guide groove 2201 provided on the inner link plate 22. Two sets of hinged rods 15 are rotatably installed on the pulling plate 16, and one end of the hinged rod 15 away from the pulling plate 16 is rotatably connected to the clamping member 14;

[0070] The energy storage kit is arranged on the pulling plate 16, and is provided with a connecting convex shaft 17. The convex shaft 17 is in rolling engagement with the retardation groove. The energy storage kit includes two sets of slide grooves 1601 arranged on the pulling plate 16. A slider 18 is slidably installed in the slide groove 1601. One side of the slider 18 is connected to the convex shaft 17, and the other end is connected to the protruding plate;

[0071] The energy storage kit also includes a transverse shaft 19 slidably connected to the protruding plate, and a second cylindrical spring 20 is sleeved on the transverse shaft 19. The two ends of the second cylindrical spring 20 are respectively connected to the protruding plate, wherein the stiffness of the second cylindrical spring 20 is much greater than the stiffness of the first cylindrical spring 8.

[0072] In this embodiment, in the initial state, the second cylindrical spring 20 is in a compressed state in advance. At this time, the cam 17 is located in the lower inclined groove 2202, and the pulling plate 16 is at the lower end of the stroke under the action of the spring force, and drives the two groups of clamping parts 14 to open through the hinge rod 15, providing sufficient space for the installation of the drive rod 4, the connecting head 12 and the roller bar 24, so that they can be smoothly placed in the installation hole 101. The compressed state of the second cylindrical spring 20 gives the cam 17 and the pulling plate 16 in cooperation with the lower inclined groove 2202 a tendency to move downward, ensuring that the two groups of clamping parts 14 are stably opened during the installation process, effectively preventing closure due to accidental touching of the clamping parts 14, and ensuring smooth installation operations.

[0073] When the driving rod 4, the connecting head 12 and the roller 24 are installed in place, the pulling plate 16 is driven in the reverse direction. The pulling plate 16 drives the slider 18 to move upward, and the convex shaft 17 moves along the lower inclined groove 2202, so that the two groups of sliders 18 move closer to each other and further compress the second cylindrical spring 20. At the same time, the pulling plate 16 drives the two groups of clamping members 14 to perform a closing action through the hinge rod 15. When the pulling plate 16 reaches the predetermined position, the convex shaft 17 moves to the protrusion, and the second cylindrical spring 20 reaches the maximum compression. Subsequently, the convex shaft 17 passes over the protrusion, and the second cylindrical spring 20 is closed. The cylindrical spring 20 releases its elastic potential energy, actively driving the cam 17 to move along the upper inclined groove 2202, pushing the clamping member 14 to continue closing until the clamping member 14 abuts against the abutment 10. The clamping member 14 pushes the abutment 10 toward the support member 6, compressing the first cylindrical spring 8. When the reaction force of the first cylindrical spring 8 and the force of the clamping member 14 acting on the abutment 10 reach a balance, the roller bar 24 is firmly fixed. At this time, the second cylindrical spring 20 still remains in a compressed state, ensuring that the clamping member 14 is stably closed and the stability of the installation of the roller bar 24 is guaranteed.

[0074] Furthermore, when the length of the roller bar 24 increases due to heat, the first cylindrical spring 8 is compressed, and its reaction force is no longer completely balanced with the force of the clamping member 14 on the abutment member 10. The clamping member 14 opens a certain angle accordingly, and the cam 17 also moves a certain displacement toward the protrusion, but the displacement is not enough to make the cam 17 move in the opposite direction over the protrusion. At this time, the first cylindrical spring 8 and the second cylindrical spring 20 work together to provide a buffer for the increase in the length of the roller bar 24, avoiding damage to the roller bar 24 due to thermal expansion. When the roller bar 24 cools and shrinks, the elastic force of the first cylindrical spring 8 and the second cylindrical spring 20 work together to restore the roller bar 24 to a stable installation state, ensuring its stability under different temperature conditions, extending the service life of the equipment, reducing equipment failures and maintenance costs caused by thermal expansion and contraction, and improving production efficiency.
