Description

Technical Field

[0001] The present application relates to the technical field of refractory fiber block production equipment, and in particular to a feeding device for producing refractory fiber blocks in a furnace. Background Art

[0002] Refractory fiber felt is made of refractory fiber as raw material, with binder added, and is made by pressure molding. It has good fire resistance and is also the raw material of refractory fiber blocks in industrial furnaces.

[0003] Refractory fiber felt is usually stored in rolls, and needs to be unrolled and loaded in the subsequent processing of refractory fiber blocks. Common unwinding equipment is mainly an unwinder, which mainly includes a frame and an expansion and contraction shaft rotatably connected to the frame. The felt roll is sleeved on the expansion and contraction shaft, and the roll can be unwound by rotating the expansion and contraction shaft.

[0004] The refractory fiber block is formed by bundling multiple layers of cotton felt. Although the uncoiler in the related art can unwind the cotton felt roll, the stacking of multiple layers of cotton felt in the production process of the refractory fiber block still needs to be done manually. In the actual production process of the refractory fiber block, the staff still have a heavy labor burden, which is not conducive to the production of refractory fiber blocks. Summary of the invention

[0005] In order to reduce the labor burden of the staff during the production process of refractory fiber blocks, the present application provides a refractory fiber block production feeding device in a furnace.

[0006] The in-furnace refractory fiber block production and feeding device provided in this application adopts the following technical solution: A feeding device for producing refractory fiber blocks in a furnace comprises a supporting assembly and a rolling device, wherein the rolling device comprises a moving assembly and an unwinding assembly, wherein the unwinding assembly is mounted on the moving assembly and is located above the supporting assembly, wherein the moving assembly is used to drive the unwinding assembly to move horizontally, wherein the unwinding assembly is used to unwind the cotton felt roll, wherein the unwinding assembly comprises a placing cylinder, wherein one end of the placing cylinder is open, and the cotton felt roll can be placed in the placing cylinder from the opening, wherein an outlet hole is provided on the upper side wall of the placing cylinder, and the end of the cotton felt roll passes through the outlet hole, wherein a rotatable friction roller is provided at the outlet hole, wherein the friction roller abuts against the cotton felt, and the rotation of the friction roller can drive the cotton felt to move.

[0007] By adopting the above technical solution, the friction roller rotates, and the end of the cotton felt is driven to move under the action of friction force, so that the cotton felt roll can be driven to rotate and unwind inside the placement tube, so that the cotton felt is continuously discharged from the discharge hole. While the cotton felt is discharged from the discharge hole, the moving component drives the unwinding component to move, so that the cotton felt can be laid on the supporting component. After the above steps are repeated many times, multiple layers of cotton felts are stacked to form an integral cotton block. The stacked integral cotton block can then be processed in the next process. During the loading process, the staff only needs to place the cotton felt roll in the placement tube. Compared with the loading method in the related art, it reduces the labor burden of the staff and improves the production efficiency of the refractory fiber block.

[0008] Optionally, two friction rollers are provided on both sides of the discharge hole, and the two friction rollers can be close to or away from each other.

[0009] By adopting the above technical solution, the cotton felt roll passes between the two friction rollers after being unrolled. The pressure between the friction rollers on the cotton felt can be adjusted by adjusting the distance between the two friction rollers, and the unrolling of cotton felts of different thicknesses can be adapted.

[0010] Optionally, the discharge hole is arranged at an angle to the moving direction of the unwinding component.

[0011] By adopting the above technical solution, the direction of the discharge hole is controlled to be tilted, so that the cotton felt is tilted away from the unwinding component along the moving direction of the unwinding component after passing through the discharge hole. In the process of stacking multiple cotton felts in sequence, the end of the subsequent cotton felt can abut against the cotton felt that has been unwound and maintain a certain pressure. Under the action of pressure, the cotton felt being unwound and the cotton felt that has been unwound can maintain a certain friction force, thereby facilitating the unwinding of the cotton felt and allowing adjacent cotton felts to fit each other.

[0012] Optionally, the moving assembly includes a crossbeam and a longitudinal beam, the longitudinal beam is arranged perpendicular to the crossbeam, a leg is arranged under the crossbeam to support the crossbeam, a pulley is arranged on the longitudinal beam to slide along its own length direction, and the unwinding assembly is installed on the pulley.

[0013] By adopting the above technical solution, the movement of the pulley can drive the unwinding assembly to move, thereby realizing the movement of the unwinding assembly.

[0014] Optionally, the longitudinal beam can move in a direction horizontally and perpendicular to its own length direction.

[0015] By adopting the above technical solution, during the process of unwinding the cotton felt by the unwinding component, the position of the unwinding component in the horizontal direction and perpendicular to the longitudinal beam can be adjusted by moving the longitudinal beam, so as to adjust the distance between the unwinding component and the cotton felt that has been laid, thereby reducing the interference between the unwinding component and the cotton felt.

[0016] Optionally, a rotating shaft is arranged between the unwinding assembly and the pulley, the rotating shaft rotates around its own axis and is connected to the pulley, and the unwinding assembly is installed on the rotating shaft; a plane parallel to the longitudinal beam and coinciding with the axis of the rotating shaft is defined as the mid-plane, and the unwinding assembly is arranged into two groups symmetrically about the mid-plane.

[0017] By adopting the above technical solution, during the production process of the refractory fiber block, the cotton felt rolls are loaded into the two placement cylinders. The unwinding assembly moves away from the staff while unwinding the cotton felt. After the unwinding of the cotton felt is completed, the two sets of unwinding assemblies can be driven to rotate by the rotating shaft, so that the positions of the two sets of unwinding assemblies are interchanged. Then the unwinding assembly moves toward the staff and unwinds again, so that the staff only needs to wait on one side for the cotton felt rolls to be loaded, thereby reducing the labor burden of the staff.

[0018] Optionally, a limiting assembly is provided on the longitudinal beam, the limiting assembly includes a mounting frame and a limiting block, the limiting block is fixed on the rotating shaft, a limiting groove is provided on the mounting frame corresponding to the limiting block, the limiting groove includes a sliding groove and a rotating groove, the sliding groove is a rectangular groove, the sliding groove is parallel to the longitudinal beam, two rotating grooves are provided at both ends corresponding to the sliding groove, the rotating groove is connected with the sliding groove, the limiting block can slide in the sliding groove along the length direction of the sliding groove, and the limiting block can rotate in the rotating groove around the axis of the rotating shaft.

[0019] By adopting the above technical solution, the limit block can slide in the sliding groove, and the sliding groove and the limit block can cooperate to limit the rotation of the rotating shaft, thereby improving the stability of the unwinding component during movement. When the cotton felt roll is unwound, the limit block enters the rotating groove, and the limit block can rotate at this time, thereby canceling the limit on the rotation of the rotating shaft, and the rotating shaft can be rotated at this time to exchange the positions of the two sets of unwinding components.

[0020] Optionally, a driving assembly is also provided on the mounting frame, and the driving assembly includes a fixing ring and an annular driving member. The fixing ring is provided with an annular mounting groove. The annular driving member is annular in structure as a whole and is a flexible mechanism. The annular driving member is installed in the mounting groove and can move circumferentially along the mounting groove. A connecting rod is provided between the annular driving member and the rotating shaft, one end of the connecting rod is connected to the annular driving member, and the other end is connected to the rotating shaft. The limiting groove is located inside the annular trajectory line of the annular driving member.

[0021] By adopting the above technical solution, the annular driving member moves along the annular trajectory, and can exert a force on the connecting rod under the action of the connecting rod, thereby driving the unwinding assembly to move linearly. And when the limit block enters the rotation groove, the direction of the force on the connecting rod under the action of the annular driving member can drive the rotating shaft to rotate automatically, thereby realizing the driving of the unwinding assembly to rotate and move linearly.

[0022] Optionally, a half-moon block is provided in the rotating groove, and a limiting surface is provided on the half-moon block. After the limiting block enters the rotating groove, the side surface of the limiting block can fit with the limiting surface, and the half-moon block can move along a circular path, and the arc length of the circular path is π.

[0023] By adopting the above technical solution, before the limit block enters the rotating groove, the half-moon block is located at one end of its sliding trajectory line, and after the limit block enters the rotating groove, it fits with the limit surface. During the rotation of the limit block, the half-moon block can be driven to rotate. Similarly, when the half-moon block rotates to the other end of the sliding trajectory line, the rotation of the limit block can be limited. At this time, the limit block rotates 180°, and when the connecting rod is acted upon by the annular driving member, it can drive the limit block to slide out of the rotating groove instead of continuing to rotate, thereby improving the smoothness of the unwinding and laying process of the cotton felt roll by the laying device.

[0024] Optionally, the annular driving member is a chain, and a sprocket engaged with the chain is provided on the mounting frame, and the sprocket is located outside the annular driving member.

[0025] By adopting the above technical solution, the annular driving member is configured as a chain, and the sprocket is arranged outside the annular driving member and meshes with the chain to drive the annular driving member. At the same time, interference between the sprocket and the rotating shaft can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-8 This application is described in further detail.

[0036] The production of refractory fiber wool blocks mainly includes the following process steps: loading, unwinding the felt roll to form multiple sheets of felt 7. Laminating, stacking multiple sheets of felt 7 in sequence to form a long strip of whole wool block. Compression, pressurizing one side of the whole wool block through an extrusion device, while bundling the whole wool block to form a compressed wool block. The compressed wool block is then cut according to size to form a furnace refractory fiber wool block.

[0037] The embodiment of the present application discloses a feeding device for producing refractory fiber blocks in a furnace.

[0038] Reference Figure 1The production and feeding device of the refractory fiber block in the furnace includes a support component 1 and a roll laying device 2. The support component 1 is used to support the cotton felt 7. The roll laying device 2 includes a moving component 21 and an unwinding component 22. The unwinding component 22 is located above the support component 1 and connected to the moving component 21. The moving component 21 is used to drive the unwinding component 22 to move in the horizontal direction. The unwinding component 22 is used to unwind the cotton felt roll. During the production and feeding process of the refractory fiber block cotton block, the cotton felt roll is placed on the unwinding component 22. While the unwinding component 22 unwinds the cotton felt 7, the moving component 21 drives the unwinding component 22 to move, so that the cotton felt 7 is placed on the support component 1. With the multiple reciprocating movements of the moving component 21 and the unwinding of multiple cotton felt rolls, multiple cotton felts 7 can be stacked layer by layer to form an integral cotton block. The extrusion equipment for extruding the integral cotton block is arranged on one side of the support component 1 along the movement direction of the unwinding device. After the integral cotton block is formed, the integral cotton felt can be driven by the support component 1 to approach the extrusion equipment for the next process.

[0039] Reference Figure 2 The support assembly 1 includes a bracket 11 and a conveying roller 12. A plurality of conveying rollers 12 are arranged in parallel and spaced apart in a direction horizontally and perpendicular to their own axes. A baffle 13 is arranged on one side of the conveying roller 12 in the length direction, and the baffle 13 is perpendicular to the ground. The cotton felt roll is parallel to the baffle 13 after unwinding. Since the cotton felt 7 is perpendicular to the ground after unwinding, the setting of the baffle 13 can reduce the tipping of the cotton felt 7. The friction between the whole cotton block and the bracket 11 is reduced by rotating the conveying roller 12, so as to facilitate the pushing of the whole cotton felt.

[0040] Reference Figure 2 The unwinding assembly 22 includes a placing tube 221 and a material-digging assembly 23. The placing tube 221 is a cylindrical shell structure as a whole, and an opening is arranged on one end face thereof facing away from the ground. The cotton felt roll can be placed in the placing tube 221 from the opening. A discharge hole 222 connected to the interior of the placing tube 221 is arranged on the side of the placing tube 221, and the end of the cotton felt roll can pass through the discharge hole 222. The material-digging assembly 23 is arranged at the discharge hole 222, and is used to apply a force to the cotton felt 7 to move the cotton felt roll outward. Under the action of the material-digging assembly 23, the end of the cotton felt 7 moves toward the outside of the placing tube 221, thereby driving the cotton felt roll to rotate as a whole, thereby realizing the unwinding of the cotton felt roll.

[0041] Reference Figure 2 The material-moving assembly 23 includes a friction roller 231, which is parallel to the placement cylinder 221. The friction roller 231 rotates around its own axis and is connected to the placement cylinder 221. The end of the cotton felt roll passes through the discharge hole 222 and abuts against the side wall of the friction roller 231. With the rotation of the friction roller, the end of the cotton felt roll can be driven to move toward the outside of the placement cylinder 221, thereby realizing the unwinding of the cotton felt roll.

[0042] Reference Figure 2The material-dispensing assembly 23 further includes an adjusting frame 232, which is located between the friction roller 231 and the placing cylinder 221, and the friction roller 231 is rotatably connected to the adjusting frame 232. The adjusting frame 232 can rotate in a direction parallel to the axis of the placing cylinder 221, and the friction roller 231 can be moved closer to or away from the feeding hole by rotating the adjusting frame 232, so that the pressure of the friction roller 231 on the cotton felt 7 can be adjusted, thereby improving the stability of the cotton felt roll during unwinding.

[0043] Reference Figure 2 The friction rollers 231 are provided as two, and the corresponding adjustment frames 232 are provided as two. The two friction rollers 231 are respectively located on both sides of the discharge hole 222. The cotton felt roll passes between the two friction rollers 231. The two friction rollers 231 exert force on the cotton felt 7 from both sides of the cotton felt 7, thereby further improving the stability of the cotton felt 7 during the unwinding process.

[0044] Reference Figure 2 The material-selecting assembly 23 further includes an adjusting block and a connecting assembly 24 which are slidably connected to the placing tube 221, and the adjusting block is arranged between the two friction rollers 231. The sliding adjusting block can make the adjusting block approach or move away from the two friction rollers 231 at the same time. The connecting assembly 24 is used to connect the adjusting block and the friction rollers 231, and the sliding adjusting block can drive the two friction rollers 231 to move closer to or away from each other. In this embodiment, an adjusting screw 25 is arranged on the adjusting block, and the adjusting screw 25 is threadedly connected to the placing tube 221, and one end of the adjusting rod is rotatably connected to the adjusting block, and rotating the adjusting screw 25 can drive the adjusting block to slide.

[0045] Reference Figure 2 The connection assembly 24 includes a pulley 241 and a belt 242. The pulleys 241 are arranged in three numbers corresponding to the friction rollers 231 and the adjustment block. The pulleys 241 are coaxially fixedly connected with the friction rollers 231. The belt 242 is wound around the multiple pulleys 241 to realize the connection between the adjustment block and the multiple friction rollers 231. At the same time, when one of the pulleys 241 rotates, it can drive the other two pulleys 241 to rotate, thereby realizing the synchronous driving of the multiple friction rollers 231. In this embodiment, the pulleys 241 on the adjustment block are directly driven by a servo motor (not shown in the figure) to realize the driving of the multiple friction rollers 231. The connection assembly 24 also includes an elastic member 243. The elastic member 243 is arranged in two numbers corresponding to the two adjustment frames 232. The elastic member 243 is used to make the adjustment frames 232 move in a direction away from each other, so that the belt 242 can always be in a tensioned state. In this embodiment, the elastic member 243 is a torsion spring, one end of which is connected to the adjustment frame 232, and the other end is connected to the placement cylinder 221.

[0046] Reference Figure 2During the production of the refractory fiber block, the moving component 21 drives the unwinding component 22 to move, and the unwinding component 22 unwinds at the same time. Under the action of the friction roller 231, the cotton felt 7 continuously extends from the discharge hole 222, so that the cotton felt 7 can be placed on the conveying roller 12 in conjunction with the baffle 13.

[0047] The direction that is horizontal and parallel to the baffle 13 is defined as the laying direction, and the penetration direction of the discharge hole 222 (which can also be understood as the discharge direction, or the direction when the cotton felt 7 extends from the placement tube 221) is set at an angle α with the laying direction, 0°<α<90°, and α is 15° in this embodiment. After passing through the discharge hole 222, the cotton felt 7 tilts toward the direction close to the baffle 13, and is deformed and fits on the baffle 13 under the action of the baffle 13. Due to the elasticity of the cotton felt 7 itself, there is a certain friction between the cotton felt 7 and the baffle 13, which makes the unwinding of the cotton felt 7 smoother during the movement of the unwinding component 22. At the same time, when another cotton felt roll is unwound again, the two adjacent cotton felts 7 can fit each other.

[0048] Reference Figure 2 The moving assembly 21 includes a sliding frame 211 and a pulley 212. The sliding frame 211 is placed on the ground. The pulley 212 is slidably connected to the sliding frame 211. The unwinding assembly 22 is installed on the pulley 212 to realize the movement of the unwinding assembly 22. The sliding frame 211 includes a crossbeam 2112, a longitudinal beam 2111 and a leg. The crossbeam 2112 is arranged at intervals of two in a direction horizontally and perpendicular to the conveying roller 12. The legs are arranged in two groups corresponding to the crossbeam 2112. Each group is arranged at two ends corresponding to the crossbeam 2112. The legs are vertically fixed under the crossbeam 2112 to support the crossbeam 2112. The longitudinal beam 2111 is arranged horizontally and perpendicular to the crossbeam 2112. Its two ends span across the two crossbeams 2112 and can slide in a direction parallel to the length direction of the crossbeam 2112. In this embodiment, the longitudinal beam 2111 is driven by a linear module. The pulley 212 includes a frame 2121 and a roller 2122, and the roller 2122 is rotatably connected to the frame 2121. A sliding groove 431 is provided on the longitudinal beam 2111, and the roller 2122 is placed in the sliding groove 431. The axis of the roller 2122 is perpendicular to the longitudinal beam 2111. Applying a force parallel to the longitudinal beam 2111 to the frame 2121 can drive the pulley 212 to move, thereby driving the unwinding assembly 22 to move.

[0049] During the production of refractory fiber blocks, the roller 2122 rolls to drive the unwinding assembly 22 to move. When a cotton felt 7 is unrolled, the longitudinal beam 2111 can be slid to adjust the distance between the baffle 13 and the unwinding assembly 22, thereby reducing the interference between the placement tube 221 and the unrolled cotton felt 7.

[0050] Reference Figure 2, a vertical plane parallel to the longitudinal beam 2111 is defined as the median plane, and two unwinding components 22 are symmetrically arranged about the median plane. The placement cylinders 221 of the two unwinding components 22 are connected to each other to form a containing member. A rotating shaft 3 is arranged between the containing member and the frame 2121, and the rotating shaft 3 is arranged vertically. One end of the rotating shaft 3 rotates around its own axis and is connected to the frame 2121, and the other end is fixed to the containing frame. The rotating axis 3 line of the rotating shaft 3 coincides with the median plane, and is located in the same plane as the axes of the two placement cylinders 221. The discharge holes 222 on the two placement cylinders 221 are located far away from each other.

[0051] During the actual unwinding process, one of the placement cylinders 221 is located on the side of the rotating shaft 3 close to the baffle 13. The other prevention cylinder is located on the side of the rotating shaft 3 away from the baffle 13. The pulley 212 moves to unwind the cotton felt roll. After the unwinding is completed, the holding member rotates to interchange the positions of the two placement cylinders 221, so that the roll laying device 2 can quickly unwind the cotton felt 7 again and place it on the support assembly 1. On the other hand, the staff only needs to wait on one side to load the cotton felt roll into the placement cylinder 221, which reduces the labor burden of the staff.

[0052] Reference Figure 2 The longitudinal beam 2111 is provided with a limit assembly 4, which includes a limit block 42 and a mounting frame 41. The mounting frame 41 is located below the vehicle frame 2121 and is fixedly connected to the longitudinal beam 2111. A limit groove 43 is provided on the side of the mounting frame 41 close to the ground, and the limit groove 43 includes a sliding groove 431 and a rotating groove 432. The sliding groove 431 is a rectangular groove parallel to the longitudinal beam 2111 in the length direction, and the rotating groove 432 is a circular groove. Two rotating grooves 432 are provided corresponding to the two ends of the sliding groove 431 in the length direction, and the two ends of the sliding groove 431 are connected to the rotating groove 432.

[0053] The limit block 42 is located in the limit groove 43, and two sliding surfaces 421 are provided on the limit block 42, which are parallel to the length direction of the sliding groove 431. The sliding surfaces 421 can fit with the side of the sliding groove 431 parallel to its own length, and the limit block 42 can slide in the sliding groove 431 along the length direction of the sliding groove 431; at the same time, the rotation of the limit block 42 can be limited by the sliding surface 421, so as to ensure the stability of the unwinding assembly 22 during the movement of the frame 2121 along the length direction of the longitudinal beam 2111. After the limit block 42 enters the rotation groove 432, it can rotate in the rotation groove 432.

[0054] During the production of the refractory fiber block, the stopper 42 first slides in the sliding groove 431, and the unwinding assembly 22 unwinds the cotton felt roll at the same time. The stopper 42 enters the rotating groove 432, and the unwinding of the cotton felt roll is completed. In this state, since the stopper 42 can rotate in the rotating groove 432, the two sets of unwinding assemblies 22 can be driven to exchange positions through the rotating shaft 3. After the position exchange is completed, the pulley 212 moves again to drive the unwinding assembly 22 to move.

[0055] A rotating surface 422 is provided on the side surface of the sliding block adjacent to the sliding surface 421. The rotating surface 422 is an arc-shaped surface. The radius of the rotating surface 422 is equal to the radius of the rotating groove 432 and is coaxial with the rotating shaft 3. When the limit block 42 is in the rotating groove 432, the rotating surface 422 can fit with the side wall of the rotating groove 432, thereby improving the stability of the limit block 42 during the rotation process in the rotating groove 432.

[0056] Reference Figure 2 The mounting frame 41 is provided with a driving assembly 5, which includes an annular driving member 51 and a fixed ring 52. The fixed ring 52 is provided with a mounting groove 53 including a sliding driving groove 531 and a rotating driving groove 532. The sliding driving groove 531 and the rotating driving groove 532 are both provided with two. The sliding driving groove 531 is an elongated structure as a whole. The two sliding driving grooves 531 are arranged on both sides of the sliding block along the direction horizontally and vertically to the length direction of the sliding groove 431. The rotating driving groove 532 is an arc-shaped structure as a whole. The rotating driving groove 532 is coaxial with the rotating groove 432. The two rotating driving grooves 532 are arranged corresponding to the two ends of the length direction of the sliding driving groove 531, and the two ends of the rotating driving groove 532 are respectively connected to the ends of the two sliding driving grooves 531 to form an annular structure. The limiting groove 43 is located inside the annular trajectory of the driving groove. The annular driving member 51 is an annular structure corresponding to the annular trajectory of the mounting groove 53 as a whole, and is a flexible mechanism. The annular driving member 51 is installed in the installation groove 53 and can move along the annular trajectory of the installation groove 53 .

[0057] Reference Figure 2 The fixing ring 52 includes a connecting ring 522 and a supporting ring 521. The connecting ring 522 is an annular cylindrical structure with two ends open, and the supporting ring 521 is an annular disc structure. The supporting ring 521 is arranged below the annular driving member 51 to support the annular driving member 51. The connecting ring 522 is located inside the annular driving member 51, and one end is welded to the supporting ring 521, and the other end is welded to the mounting frame 41, so as to realize the fixed connection between the fixing ring 52 and the mounting frame 41.

[0058] A connecting rod 54 is provided between the annular driving member 51 and the rotating shaft 3. The connecting rod 54 is a cylindrical rod and is arranged parallel to the rotating shaft 3. One end of the connecting rod 54 is connected to the annular driving part, and the other end is connected to the rotating shaft 3. The annular driving member 51 moves along its own circumferential direction, and can drive the connecting rod 54 to reciprocate in the length direction of the longitudinal beam 2111, thereby realizing the reciprocating drive of the pulley 212.

[0059] In this embodiment, the annular driving member 51 is a chain, and a sprocket 55 is disposed outside the annular driving member 51, and the sprocket 55 meshes with the chain, so as to drive the chain to move. The chain abuts against the outer wall of the support ring 521 to reduce the bending of the chain toward the inside of the support ring 521 during movement, and improve the stability of the engagement between the chain and the sprocket 55. A protective cover (not shown in the figure) can be provided outside the chain to reduce the occurrence of external dust contacting the chain, and at the same time, it can reduce the possibility of the chain injuring people.

[0060] Reference Figure 2 , an auxiliary release component 6 for limiting the rotation of the limit block 42 is provided in the rotating groove 432. The auxiliary release component 6 includes a half-moon block 61, which is provided on the side wall of the rotating groove 432 and is slidably connected to the side wall of the rotating groove 432 in the circumferential direction along the side wall of the rotating groove 432. The half-moon block 61 is provided with an arc-shaped matching surface 611 that fits with the side wall of the rotating groove 432, and a limiting surface 612 that is flush with one of the side walls of the sliding groove 431. After the limit block 42 enters the rotating groove 432, the sliding surface 421 of the limit block 42 fits with the limiting surface 612. A travel groove 62 is provided on the side wall of the rotating groove 432 facing away from the ground, and a control rod 63 is provided on the side of the half-moon block 61 corresponding to the travel groove 62, one end of the control rod 63 is welded to the half-moon block 61, and the other end is inserted into the travel groove 62. The travel groove 62 is an arc-shaped groove, and the arc trajectory of the travel groove 62 is π. Under normal circumstances, the control rod 63 is located at one end of the travel groove 62. After the limit block 42 enters the rotation groove 432, it drives the half-moon block 61 to rotate. After the control rod 63 moves to the other end of the travel groove 62, the travel groove 62 limits the control rod 63, and then limits the rotation of the half-moon block 61, thereby limiting the rotation of the limit block 42, making it easier for the limit block 42 to slide out of the rotation groove 432.

[0061] The release assisting assembly 6 also includes a reset member 65, which is used to apply a force to the half-moon block 61 to rotate the half-moon block 61. This allows the half-moon block 61 to be stably in a certain state, and can automatically reset after the limit block 42 drives the half-moon block 61 to rotate. In this embodiment, the reset member 65 is a spring. A receiving groove 64 is provided on the side of the travel groove 62 away from the ground, and the receiving groove 64 includes an arc portion corresponding to the travel groove 62 and a linear portion 642 whose length direction is parallel to the length direction of the sliding groove 431. One end of the linear portion 642 is connected to one end of the arc portion 641. The reset member 65 is arranged in the linear portion 642, and one end is welded to the control rod 63, and the other end is welded to the side wall of the linear portion 642. The rotation of the half-moon block 61 drives the reset member 65 to extend along the length direction of the receiving groove 64. After the limit block 42 is separated from the half-moon block 61, the half-moon block 61 is automatically reset under the action of the reset member 65.

[0062] The implementation principle of the in-furnace refractory fiber block production feeding device of the embodiment of the present application is as follows: during the refractory fiber block production process, the staff loads the cotton felt roll into the placement cylinder 221 at one end of the support assembly 1, and inserts the end of the cotton felt roll between the two friction rollers 231. Then the sprocket 55 rotates to drive the annular drive member 51 to move, thereby applying a force to the rotating shaft 3. Under the action of the force, the slide 212 moves to drive the unwinding assembly 22 to move. At the same time, the unwinding assembly 22 unwinds the cotton felt roll, so that the cotton felt roll unfolds and falls on the support assembly 1. After the cotton felt roll is unwound, the limit block 42 enters the rotating groove 432, and the annular drive member 51 drives the rotation, so that the positions of the two unwinding assemblies 22 are exchanged, and then the pulley 212 drives the unwinding assembly 22 to reset to the position of the staff, and the staff loads the cotton felt roll again, repeats the loading action, and realizes the rapid loading of the refractory fiber block production, reducing the labor burden of the staff.

[0063] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
