Description

Technical Field

[0001] This utility model relates to the field of kiln auxiliary equipment technology, specifically to an automatic rod-pulling device for kilns. Background Technology

[0002] In building ceramics enterprises, the kiln process is one of the most important processes in ceramic tile production. During the production process, ceramic powder is pressed into brick blanks by a press and then put into the kiln for firing. During this process, a lot of fine powder will stick to the bottom of the brick blank. Even if magnesium oxide slurry is applied to the bottom of the brick blank for isolation later, a small amount of fine powder will still stick to the rollers while the tiles are being fired at high temperature and conveyed on the roller conveyor platform in the kiln. After a long period of accumulation, these fine powders will clump on the rollers, forming nails, which will lead to uneven brick feeding and affect product quality.

[0003] Therefore, to solve the problem of uneven brick movement caused by fine powder sticking to the kiln rollers and forming nails, it is necessary to regularly pull out the rollers for cleaning. At present, the rollers are pulled out manually. Because the firing is carried out at a high temperature of over 1,000 degrees Celsius, even if cooling preparations are made in advance, the temperature of the pulled-out rollers is still above 500 degrees Celsius. After being pulled out, they need to be placed on a roller machine to be cooled while rotating at a constant speed to prevent deformation of the high-temperature rollers. This is not only labor-intensive and resource-intensive, but also cumbersome and inefficient.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0071] Currently, the removal of rollers is done manually. When employees manually remove the rollers, the temperature of the removed rollers is still above 500℃. After removal, the ambient temperature is extremely high, and the operation method can also affect the rollers, causing them to break or be damaged, increasing the cost of rollers. In addition, the removed rollers need to be rotated on the roller removal machine to cool down before being removed and cleaned. Otherwise, the rollers are prone to deformation or damage. When operating manually, employees work in high temperatures, and only one roller can be cooled and processed at a time. The labor intensity of employees is high, the roller processing time is long, and the efficiency is low, which is not conducive to improving production and quality.

[0072] In view of the shortcomings of the prior art, this embodiment provides an automatic rod-pulling device for kilns, as detailed below:

[0073] As attached Figure 1 and attached Figure 2As shown, an automatic rod-pulling device for kilns includes a frame 1, a rod-pulling assembly 2, a turnover conveyor chain 3, a transfer cooling conveyor chain 4, a feeding assembly 5, and a collection frame 6. The frame 1 is fixed with profiles, which not only facilitates assembly but also saves costs. The rod-pulling assembly 2 is slidably mounted on the top of the frame 1, and the height of the rod-pulling assembly 2 is the same as the height of the conveyor roller table inside the kiln, so as to facilitate the cooperation between the rod-pulling assembly 2 and the roller, and to pull the roller out of the conveyor roller table by sliding the rod-pulling assembly 2. The turnover conveyor chain 3 is mounted on the frame 1 and located at the bottom of the rod-pulling assembly 2, so that the roller pulled out by the rod-pulling assembly 2 is placed on the turnover conveyor chain 3. The transfer cooling conveyor chain 4 is also provided. The rollers are placed on the frame 1 and located on one side of the turnover conveyor chain 3. The turnover conveyor chain 3 works in conjunction with the intermediate cooling conveyor chain 4 to transfer the rollers on the turnover conveyor chain 3 to the intermediate cooling conveyor chain 4. This not only facilitates the collection of the rollers but also makes it easier for the roller-pulling assembly 2 to work in the next cycle. Both the turnover conveyor chain 3 and the intermediate cooling conveyor chain 4 can drive the rollers to rotate on them, which can effectively prevent the rollers from bending due to uneven stress at high temperatures. After passing through the intermediate cooling conveyor chain 4, the rollers can be picked up by the unloading assembly 5 on one side of the frame 1 and placed into the collection frame 6. The collection frame 6 is located on one side of the frame 1 and can be moved independently, while the unloading assembly 5 is located on top of the collection frame 6.

[0074] Specifically, both the bottom of the frame 1 and the bottom of the collection frame 6 are equipped with casters, which are existing technology and have a locking function. The frame 1 can be moved to one side of the conveyor roller table inside the kiln, and then the roller can be pulled out by sliding the puller assembly 2 to the pull-out side of the roller. The puller assembly 2 is then engaged with the roller, and the roller can be pulled out by sliding the puller assembly 2 away from the roller. The roller is then placed on the turnover conveyor chain 3, which simultaneously drives the roller to move and rotate. Then it moves to the intermediate cooling conveyor chain 4. The intermediate cooling conveyor chain 4 is longer, which can drive the roller to move for a longer time and also drive the roller to rotate. This not only dissipates heat but also ensures that the roller is evenly stressed during movement, preventing bending of the unsupported roller and damage to the roller. Then the unloading assembly 5 grabs the cooled roller and puts it into the collection frame 6. The collection frame 6 is then moved to the next process location by manual labor or auxiliary equipment.

[0075] This application uses the rod-pulling assembly 2 to pull out the rollers from the conveyor roller table inside the kiln and place them on the turnover conveyor chain 3, and then convey them to the intermediate cooling conveyor chain 4. Together with the unloading assembly 5, it can realize an automatic and fast rod-pulling process, which can effectively save manpower and material resources. At the same time, both the turnover conveyor chain 3 and the intermediate cooling conveyor chain 4 can drive the rollers to rotate, which can make the rollers be subjected to uniform force and cooled during the conveying process, so as to connect with the rod-pulling process and effectively improve its working efficiency.

[0076] In this embodiment, the frame 1 includes a first profile frame and a second profile frame. The rod pulling assembly 2 and the turnover conveyor chain 3 are both located on the first profile frame, and the intermediate cooling conveyor chain 4 and the unloading assembly 5 are located on the second profile frame. By setting up two profile frames, it also facilitates maintenance and transportation.

[0077] One embodiment of this application is shown in the appendix. Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the rod pulling assembly 2 includes two slide rail assemblies 21, a sliding plate 22, multiple linkage drive assemblies 23, and two grippers 24. The two slide rail assemblies 21 are respectively disposed on both sides of the top of the first profile frame. The sliding plate 22 is disposed on the two slide rail assemblies 21 and can move towards or away from the kiln conveying roller table under the action of the two slide rail assemblies 21. Multiple linkage drive assemblies 23 are spaced apart on the sliding plate 22. Each linkage drive assembly 23 includes two linkage moving ends at the end away from the sliding plate 22. Each linkage moving end is rotatably provided with a gripper 24. The linkage drive assembly 23 cooperates with the two grippers 24 and can drive the grippers 24 to move towards or away from each other.

[0078] Initially, the two grippers 24 are separated. During operation, the sliding plate 22 moves to a position close to the roller under the action of the slide rail assembly 21, and the two grippers 24 are located on the upper and lower sides of the roller respectively. Through the connecting rod drive assembly 23, the two grippers 24 can be driven to move towards each other and clamp the roller. Then, under the action of the slide rail assembly 21, the roller is pulled out and continues to move to the top of the turnover conveyor chain 3. Then, under the action of the connecting rod drive assembly 23, the two grippers 24 release the roller, and the roller is placed on the turnover conveyor chain 3 for conveying.

[0079] In this embodiment, as shown in the appendix Figure 4 As shown, the linkage drive assembly 23 includes a fixed rod 231, two drive cylinders 232, and two support rods 234. The fixed rod 231 is located at the bottom of one side of the sliding plate 22, and the two drive cylinders 232 are located at the top of one side of the sliding plate 22. The extended ends of the two drive cylinders 232 are provided with drive rods 233. The drive rods 233 can be moved by the extension and retraction of the two drive cylinders 232. The drive rods 233 and the fixed rod 231 are located on the same side of the sliding plate 22. Multiple support rods 234 are rotatably arranged on the fixed rod 231 and the drive rods 233, and the support rods 234 on the fixed rod 231 correspond one-to-one with the support rods 234 on the drive rods 233 and rotate in a crisscross manner. The corresponding two support rods 234 form an "X" shape. A gripper 24 is rotatably arranged at each end of the two support rods 234 away from the sliding plate 22.

[0080] By activating the two drive cylinders 232, the drive rod 233 can be moved toward the fixed rod 231. Through the action of the two support rods 234, the two grippers 24 can also be moved toward each other, thereby clamping the roller.

[0081] In this embodiment, as shown in the appendix Figure 5 As shown, the gripper 24 includes an arc-shaped plate 241, two support blocks 242, and two rollers 243. The arc-shaped plate 241 is semi-circular, and its protrusion is rotatably connected to the support rod 234. A damper is provided between the arc-shaped plate 241 and the support rod 234 to prevent the arc-shaped plate 241 from rotating too much and failing to cooperate with the other gripper 24. The arc-shaped plate 241 and the support rod 234 rotate at a small angle to facilitate the adjustment of the two grippers 24 to a state where they can grip the roller. The concave part of the arc-shaped plate 241 is symmetrically provided with two support blocks 242, and each support block 242 is provided with two symmetrical rollers 243, which cooperate with the roller.

[0082] The four rollers 243 can effectively fix one side of the roller bar, and then cooperate with another gripper 24 to achieve the clamping function; when the arc plate 241 rotates at a certain angle, it will abut against the support rod 234, thus avoiding the problem that the arc plate 241 rotates too much under the weight of the roller bar, causing the roller bar to tilt downward at a large angle.

[0083] In this embodiment, as shown in the appendix Figure 2 As shown, the slide rail assembly 21 includes two first slide rails 211, guide screws 213, and a drive motor 214. The two first slide rails 211 are respectively disposed on the top sides of the first profile frame. A first slider 212 is disposed on the first slide rail 211. The two ends of the sliding plate 22 are respectively disposed on the two first sliders 212. Two guide screws 213 are also disposed on the top sides of the first profile frame. The sliding plate 22 is threadedly engaged with the guide screws 213. The top of the frame 1 is provided with a drive motor 214, which is connected to the guide screws 213. The drive motor 214 can drive the guide screws 213 to rotate, thereby driving the first sliding plate 22 to move.

[0084] Furthermore, one of the guide screws 213 is threaded, and the other is not threaded, while the drive motor 214 is connected to the threaded guide screw 213.

[0085] One embodiment of this application is shown in the appendix. Figure 2 As shown, the turnover conveyor chain 3 includes two first vertical modules 31, which are symmetrically arranged inside the first profile frame and located at both ends of the first profile frame. The line connecting the two first vertical modules 31 is perpendicular to the line connecting the two slide rail assemblies 21. The slider of the first vertical module 31 is provided with a first conveying roller group 32. The first vertical module 31 is the prior art.

[0086] In this embodiment, as shown in the appendix Figure 3 As shown, the first conveyor roller group 32 includes a support 321, a conveyor chain 322, multiple fixed blocks 323, a rotating roller 324, two drive gears 327, a self-rotating motor 328, and a revolution motor 329. The two ends of the support 321 are semi-circular. The conveyor chain 322 is arranged around the outer surface of the support 321, and multiple fixed blocks 323 are evenly distributed on the conveyor chain 322. Rotating rollers 324 are rotatably mounted inside the multiple fixed blocks 323. One end of the rotating roller 324 is equipped with a self-rotating gear 325, and the other end is equipped with a conveyor wheel 326. Two drive gears 327 are also provided on one side of the support 321. The drive gears 327 are respectively positioned... On both sides of the bracket 321, drive chains (not shown in the figure) are fitted on the two drive gears 327. The drive chains are connected to multiple rotating gears 325 on the top of the bracket 321. The bracket 321 is also equipped with a rotating motor 328 and a revolving motor 329. The rotating motor 328 is connected to the drive gear 327 through a chain or belt to drive the drive gear 327 to rotate. A chain gear is also rotatably installed inside the bracket 321. The chain gear meshes with the conveyor chain 322 outside the bracket 321. The chain gear is coaxially connected to the revolving motor 329. The revolving motor 329 can drive the chain gear and the conveyor chain 322 to rotate.

[0087] The aforementioned self-rotating motor 328 and revolution motor 329 can drive the conveyor chain 322 to rotate and the multiple self-rotating gears 325 located at the top of the bracket 321 to rotate, thereby causing the conveyor rollers to rotate while moving.

[0089] The first vertical module 31, the second vertical module 41, and the third vertical module 43 are arranged at intervals. A connecting conveyor belt is provided between the first conveyor roller group 32 and the second conveyor roller group 42, and between the second conveyor roller group 42 and the third conveyor roller group 44, for conveying roller bars. Alternatively, the first vertical module 31, the second vertical module 41, and the third vertical module 43 are arranged laterally in a staggered manner, so that the first conveyor roller group 32 and the second conveyor roller group 42, and between the second conveyor roller group 42 and the third conveyor roller group 44 are staggered. That is, one end of the first conveyor roller group 32 is located between two second conveyor roller groups 42, and one end of the second conveyor roller group 42 is located between two third conveyor roller groups 44, which can save the connecting conveyor belts between them, thereby achieving the purpose of conveying roller bars.
