Description

Technical Field

[0001] This utility model belongs to the technical field of roller kilns, and specifically relates to a high-efficiency transmission device for roller kilns and roller kilns. Background Technology

[0002] Roller kilns enable continuous production. From the input of the raw material, it sequentially undergoes high-temperature firing, cooling and annealing processes, directly outputting the finished product. This achieves continuous production with high efficiency and low energy consumption. During the production process, the finished products (such as lithium battery materials and daily-use ceramics) after firing in the kiln need to be transported through the roller kiln's efficient transmission device.

[0003] When multiple rows of products, after being calcined in the kiln, are successively conveyed out of the kiln outlet, the heads of the products in each row are not aligned. Related technologies utilize roller kilns with high-efficiency transmission devices that include an acceleration section, with a movable baffle at the end of this section. When products conveyed from the kiln outlet reach the acceleration section, they are propelled by the acceleration section to move rapidly to its end. The baffle protrudes from the acceleration section to prevent further movement until all products in the same row are against the baffle, thus aligning the heads of multiple products in the same row. However, during this alignment process, due to the time difference in arrival at the acceleration section for different products in the same row, the maximum distance between products in the same row is prolonged, leading to a longer dwell time at the baffle and affecting overall production efficiency. Furthermore, the longer the products remain at the baffle, the more severe the wear on the bottom contact surface of the products, and the shorter the lifespan of the baffle. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency transmission device for roller kilns, reducing the friction time between the baffle and the product during the alignment process.

Under the action of the drive member, at least a portion of the baffle can protrude from the bearing surface of the conveyor belt.

[0011] According to an embodiment of the present invention, a high-efficiency transmission device for a roller kiln has first transmission rollers arranged on different transmission shafts along the conveying direction of the conveyor belt to form a transmission channel.

[0012] According to an embodiment of the present invention, a high-efficiency transmission device for a roller kiln is provided. The transmission device further includes a detector, which includes a sensing part and a fixed base. The sensing part is mounted on the fixed base, and the fixed base is fixed to the base frame. The sensing part is arranged corresponding to the speed change section.

[0013] According to an embodiment of the present invention, in the high-efficiency transmission device of the roller kiln, along the conveying direction of the conveyor belt, the distance between the sensing part and the auxiliary section is greater than or equal to the maximum spacing between different products located in the same row.

[0014] According to an embodiment of the present invention, the high-efficiency transmission device for a roller kiln includes an overrunning clutch, wherein the input end of the overrunning clutch is connected to the output shaft of the first driver, and the output end of the overrunning clutch is connected to the first transmission roller.

[0015] According to an embodiment of the present invention, the high-efficiency transmission device for a roller kiln includes a first synchronous belt and a plurality of first synchronous pulleys. The first synchronous pulleys correspond one-to-one with the transmission shaft, and the first synchronous pulleys are connected to the transmission shaft. The first synchronous belt is wound around the plurality of synchronous pulleys. The output shaft of the first driver is connected to one of the synchronous pulleys.

[0016] According to an embodiment of the present invention, a high-efficiency transmission device for a roller kiln includes a baffle plate comprising a stop portion, a rotating portion, and a connecting portion. The stop portion protrudes from the bearing surface of the conveyor belt. The rotating portion is connected to the connecting portion and the stop portion and is rotatably connected to the base frame. The output shaft of the drive member is rotatably connected to the connecting portion.

[0017] According to an embodiment of the present invention, the high-efficiency transmission device for a roller kiln includes a speed-changing section comprising a plurality of second transmission rollers arranged along the conveying direction of the conveyor belt; along the width direction of the conveyor belt, the length of the stop portion is greater than or equal to two-thirds of the length of the second transmission rollers.

[0018] According to an embodiment of the present invention, the high-efficiency transmission device for a roller kiln includes a second synchronous belt, a second driver, and a plurality of second synchronous pulleys. The second synchronous pulleys and the second transmission rollers correspond one-to-one. The second synchronous pulleys are connected to the second transmission rollers. The second synchronous belt is wound around the plurality of synchronous pulleys. The second driver is mounted on the base frame, and the output shaft of the second driver is connected to one of the synchronous pulleys.

[0019] According to an embodiment of the present invention, the high-efficiency transmission device for a roller kiln further includes a transmission section along the conveying direction of the conveyor belt, the transmission section being located in front of the speed-changing section.

[0020] A second aspect of this utility model provides a roller kiln, including a conveying component, a kiln body, and a high-efficiency transmission device for a roller kiln as described in any of the first aspects of the present invention. The conveying component is disposed inside the kiln body and is connected to the auxiliary section.

[0021] The present invention has at least the following beneficial effects:

[0022] Multiple rows of products are arranged on a conveyor belt. When at least part of the products in the same row are located in the variable speed section, the transmission speed of the variable speed section is greater than that of the auxiliary section, so that the products on the variable speed section move faster to the end of the variable speed section. Since some products are located in both the variable speed section and the auxiliary section, the rotation speed of the corresponding first drive roller is greater than that of the drive shaft, which speeds up the products on the variable speed section to move quickly to the baffle for alignment. This also reduces the time difference between the products in the same row reaching the baffle and reduces the time the products stay at the baffle, thereby reducing the friction between the baffle and the products. At this time, the clutch controls the first driver and the first drive roller to disconnect, so as to avoid damage to the first driver caused by the accelerated rotation of the first drive roller under the action of the variable speed section. At the same time, the disconnection of the first driver and the first drive roller allows the first drive roller to increase its rotation speed with the products, reducing the friction between the first drive roller and the products, thereby accelerating the products to reach the baffle. The baffle protrudes from the bearing surface of the conveyor belt, so that the baffle can intercept the products on the variable speed section, thereby aligning the heads of the products in the same row. If not all products in the same row have moved to the speed-changing section or if products in the same row in the speed-changing section have completed alignment, the clutch controls the first driver and the first transmission roller to connect. Under the action of the first driver, all the first transmission rollers in the auxiliary section return to their original speed, and the transmission speeds of the speed-changing section and the auxiliary section are the same, so that the products in the auxiliary section can be smoothly transmitted to the speed-changing section. At this time, the baffle descends below the bearing surface of the conveyor belt, so that the products in the same row with aligned heads can continue to move on the conveyor belt.

[0042] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0043] Reference Figures 1 to 8 The following are several embodiments of the high-efficiency transmission device and roller kiln of this utility model.

[0044] like Figures 1 to 4 As shown, the high-efficiency transmission device of the roller kiln according to the first aspect of this utility model includes a base frame 100, a conveyor belt 200, and a stop assembly 300; the conveyor belt 200 includes an auxiliary section 210 and a speed-changing section 220 arranged along the conveying direction of the conveyor belt 200, and the product 400 is transmitted to the speed-changing section 220 via the auxiliary section 210; the auxiliary section 210 includes a plurality of components arranged along the conveying direction of the conveyor belt (e.g., ...). Figure 1 and Figure 2 The system comprises a drive shaft 211, a clutch 212, and a first driver 213 arranged in direction a). Multiple first drive rollers 240 are mounted on the drive shaft 211, each first drive roller 240 being sleeved outside the drive shaft 211 and rotating relative to it. The first drive rollers 240 are rotatably connected to the base frame 100, and the output shaft of the first driver 213 is connected to each first drive roller 240. Each clutch 212 corresponds to one of the first drive rollers 240, and the first drive rollers 240 are connected via clutches. The clutch 212 is connected to the drive shaft 211; when the rotational speed of the first drive roller 240 is greater than the rotational speed of the drive shaft 211, the clutch 212 controls the first drive roller 240 and the drive shaft 211 to disconnect; the stop assembly 300 includes a baffle 310 and a drive member 320, the baffle 310 is disposed at the end of the speed change section 220; the drive member 320 is disposed on the base frame 100, and under the action of the drive member 320, at least a portion of the baffle 310 can protrude from the bearing surface 230 of the conveyor belt.

[0045] Multiple rows of products 400 are arranged on conveyor belt 200. When at least part of the products 400 in the same row are located on speed-changing section 220, the transmission speed of speed-changing section 220 is greater than the transmission speed of auxiliary section 210, so that the products 400 on speed-changing section 220 move faster to the end of speed-changing section 220. Since some products 400 are located on both speed-changing section 220 and auxiliary section 210 at the same time, the rotation speed of the corresponding first transmission roller 240 is greater than the rotation speed of transmission shaft 211, which speeds up the movement of products 400 on speed-changing section 220 to the baffle 310 for alignment. This also reduces the time difference between the products 400 in the same row reaching the baffle 310, reduces the time the products 400 stay at the baffle 310, and thus reduces [the risk of contamination]. The baffle 310 rubs against the product 400; at this time, the clutch 212 controls the first driver 213 and the first transmission roller 240 to disconnect, so as to avoid damage to the first driver 213 caused by the first transmission roller 240 accelerating its rotation under the action of the speed change section 220. At the same time, the first driver 213 and the first transmission roller 240 are disconnected, so that the first transmission roller 240 can accelerate its rotation speed with the product 400, reducing the friction between the first transmission roller 240 and the product 400, thereby accelerating the product 400 to reach the baffle 310; the baffle 310 protrudes from the bearing surface 230 of the conveyor belt, so that the baffle 310 can intercept the product 400 on the speed change section 220, thereby aligning the heads of the products 400 in the same row. If not all products 400 in the same row have moved to the speed-changing section 220 or if the products 400 in the same row on the speed-changing section 220 have completed alignment, the clutch 212 controls the first driver 213 and the first transmission roller 240 to connect. Under the action of the first driver 213, all the first transmission rollers 240 of the auxiliary section 210 resume their original rotational speed, and the transmission speeds of the speed-changing section 220 and the auxiliary section 210 are the same, so that the products 400 on the auxiliary section 210 can be smoothly transmitted to the speed-changing section 220. At this time, the baffle 310 descends below the bearing surface 230 of the conveyor belt 200, so that the aligned products 400 in the same row can continue to move on the conveyor belt 200. Figure 1 A schematic diagram of the high-efficiency transmission device of the roller kiln when the baffle 310 protrudes from the bearing surface 230 of the conveyor belt; Figure 2 This is a schematic diagram of the high-efficiency transmission device of the roller kiln when the baffle 310 descends below the bearing surface 230 of the conveyor belt 200.

[0046] Product 400 typically refers to lithium battery materials and everyday ceramics. Generally, to prevent damage and contamination of the body and glaze by gases and harmful substances, the raw materials for lithium battery materials and everyday ceramics are fired in a container made of refractory material; this container is called a sagger. The alignment of Product 400 mentioned in this article refers to the alignment of the heads of the saggers.

[0047] In some embodiments, such as Figure 4As shown, along the conveying direction of the conveyor belt 200, the first drive rollers 240 on different drive shafts 211 are arranged to form a transmission channel 280. When the products 400 are arranged in the auxiliary section 210, multiple rows of products 400 are arranged on the transmission channel 280 along the conveying direction of the conveyor belt 200; the first drive rollers 240 on different drive shafts 211 are arranged along the conveying direction of the conveyor belt 200, so that the products 400 on the auxiliary section 210 are driven on different first drive rollers 240, thereby making the conveying of the products 400 more stable and reducing the shaking of the products 400. In this embodiment, four first drive rollers 240 are provided on a drive shaft 211, namely a first roller 241, a second roller 242, a third roller 243, and a fourth roller 244. The first rollers 241 on different drive shafts 211 are arranged along the conveying direction of the conveyor belt 200, the second rollers 242 on different drive shafts 211 are arranged along the conveying direction of the conveyor belt 200, the third rollers 243 on different drive shafts 211 are arranged along the conveying direction of the conveyor belt 200, and the fourth rollers 244 on different drive shafts 211 are arranged along the conveying direction of the conveyor belt 200, so that four rows of products 400 can be stably driven on the auxiliary section 210. Of course, in other embodiments, two, three, five, or six first drive rollers 240 may also be provided on the drive shaft 211, and this embodiment of the present invention does not particularly limit this.

[0048] In some embodiments, the clutch 212 is an overrunning clutch. The input end of the overrunning clutch is connected to the output shaft of the first driver 213, and the output end of the overrunning clutch is connected to the first drive roller 240. When the conveyor belt 200 is in the driving state, the overrunning clutch connects the first driver 213 to drive the first drive roller 240 to rotate, thereby driving the auxiliary section 210 to drive. When the conveyor belt 200 is in the aligned state, the speed change section 220 starts to accelerate. Since the front half of some products 400 is located in the speed change section 220 and the rear half is located in the auxiliary section 210, the input and output ends of the overrunning clutch are disconnected at this time, so that the rotation speed of the first drive roller 240 in the auxiliary section 210 increases with the speed change section 220, avoiding damage to the first driver 213 due to the accelerated rotation of the first drive roller 240. The specific structure of the overrunning clutch is existing technology. The overrunning clutch is an important component used for the power transmission and separation between the prime mover and the working machine or between the drive shaft and the driven shaft inside the machine. It is a device that has a self-engaging function by utilizing the speed change or rotation direction change of the drive and driven parts. When the speed of the working machine or the driven shaft exceeds the speed of the prime mover or the drive shaft, the overrunning clutch automatically cuts off the power transmission between the prime mover and the working machine or between the drive shaft and the driven shaft inside the machine, so that the drive shaft and the driven shaft inside the machine are freed from the restraint of the prime mover and the working machine and continue to rotate at a speed exceeding that of the prime mover or the drive shaft.

[0049] In some embodiments, such as Figure 2 As shown, the transmission device also includes a detector 500, which includes a sensing unit and a fixed base. The sensing unit is mounted on the fixed base, which is fixed to the base frame 100. The sensing unit is positioned opposite to the speed-changing section 220. When a product 400 on the speed-changing section 220 triggers the sensing unit, the conveyor belt 200 switches from a transmission state to an alignment state. The sensing unit is positioned opposite to the speed-changing section 220. When a product 400 on the speed-changing section 220 triggers the sensing unit, it indicates that the product 400 has moved to a specific position on the speed-changing section 220. At this time, the speed-changing section 220 accelerates, causing the product 400 on the speed-changing section 220 to accelerate to the end of the speed-changing section 220, and the heads of each product 400 in the same row are aligned by the baffle 310. The position of the product 400 on the speed-changing section 220 can be obtained through the detector 500. The sensing unit may include a transmitter and a receiver, which are symmetrically arranged relative to the speed-changing section 220. The receiver is used to receive the light emitted by the transmitter.

[0050] In some embodiments, such as Figures 1 to 2 As shown, along the conveying direction of the conveyor belt 200, the distance between the sensing unit and the auxiliary section 210 is greater than or equal to the maximum spacing between different products 400 located in the same row, so that when the product 400 at the front of the same row triggers the sensing unit, the product 400 at the back of the same row is at least partially located on the speed-changing section 220, so as to ensure that in the aligned state of the conveyor belt 200, the speed-changing section 220 can drive the products 400 in the same row to accelerate.

[0051] In some embodiments, such as Figures 1 to 2 As shown, the conveyor belt 200 also includes a first synchronous belt 250 and multiple first synchronous pulleys. Each first synchronous pulley corresponds to a first transmission roller 240, and the first synchronous pulleys and first transmission rollers 240 are connected via a clutch 212. The first synchronous belt 250 is wound around the multiple synchronous pulleys. The output shaft of the first driver 213 is connected to one of the synchronous pulleys, enabling the first driver 213 to drive the multiple first transmission rollers 240 to move synchronously, ensuring stable transmission of the product 400 on the auxiliary section 210. Generally, the first driver 213 is a motor.

[0052] In some embodiments, such as Figure 3As shown, the baffle 310 includes a stop portion 311, a rotating portion 312, and a connecting portion 313. The rotating portion 312 is connected to the connecting portion 313 and the stop portion 311. The stop portion 311 can protrude from the bearing surface 230 of the conveyor belt. The rotating portion 312 is rotatably connected to the base frame 100. The output shaft of the drive member 320 is rotatably connected to the connecting portion 313. When the drive member 320 operates, its output shaft extends, and the baffle 310 rotates in the forward direction, causing the stop portion 311 to at least partially protrude from the bearing surface 230 of the conveyor belt 200. When the drive member 320 operates again, its output shaft retracts, and the baffle 310 rotates in the reverse direction, causing the stop portion 311 to be lower than the bearing surface 230 of the conveyor belt 200, so that the aligned product 400 can continue to move on the conveyor belt 200. Generally, the drive member 320 is a cylinder.

[0053] In some embodiments, such as Figures 3 to 4 As shown, the speed change section 220 includes a plurality of second drive rollers 221 arranged along the conveying direction of the conveyor belt. The product 400 moves on the second drive rollers 221, and the second drive rollers 221 rotate to drive the product 400 to be driven on the speed change section 220. Along the width direction of the conveyor belt 200, the length of the stop portion 311 is greater than or equal to the length of the second drive roller 221 to ensure that the stop portion 311 can abut against the plurality of products 400 arranged side by side on the second drive roller 221, that is, the stop portion 311 can align the products 400 in the same row.

[0054] The conveyor belt 200 has a bearing surface 230, which is the upper surface of the conveyor belt 200. The product 400 on the conveyor belt 200 is placed on the bearing surface 230 of the conveyor belt 200. Specifically, the bearing surface 230 of the auxiliary section 210 is formed by connecting the outer surfaces of multiple first drive rollers 240, and the bearing surface 230 of the speed-changing section 220 is formed by connecting the outer surfaces of multiple second drive rollers 221. The number of first drive rollers 240 can be two, three, four, or five, and the number of second drive rollers 221 can be two, three, four, or five. Of course, the number of first drive rollers 240 and second drive rollers 221 can be set according to actual needs, and this embodiment of the utility model does not make any special limitation in this regard.

[0055] In some embodiments, such as Figures 1 to 2 As shown, the conveyor belt 200 also includes a second synchronous belt 260, a second driver 290, and multiple second synchronous pulleys. The second driver 290 is mounted on the base frame 100, and its output shaft is connected to one of the synchronous pulleys. The second synchronous pulleys are connected to second drive rollers 221, and the second synchronous belt 260 is wound around the multiple synchronous pulleys, enabling the second driver 290 to drive the multiple second drive rollers 221 to move synchronously, thus ensuring stable transmission of the product 400 in the speed-changing section 220. Generally, the second driver 290 is a motor.

[0056] In some embodiments, such as Figures 1 to 2 As shown, the conveyor belt 200 also includes a drive section 270. Along the conveying direction of the conveyor belt, the drive section 270 is located in front of the speed change section 220. In the transmission state of the conveyor belt 200, the aligned product 400 moves from the speed change section 220 to the drive section 270, and the drive section 270 sends the aligned product 400 to the next process.

[0057] like Figures 5 to 8 As shown, taking the auxiliary section 210 carrying three rows of products 400 as an example, from the speed change section 220 to the auxiliary section 210, the three rows of products 400 are respectively the first row of products 410, the second row of products 420, and the third row of products 430; initially, the transmission speeds of the speed change section 220 and the auxiliary section 210 are the same; when all the products 400 of the first row of products 410 are partially or completely located in the speed change section 220, the second driver 290 controls the rotation speed of the second transmission roller 221 of the speed change section 220 to increase, thereby making the transmission speed of the speed change section 220 greater than the transmission speed of the acceleration section; as Figure 6 As shown, since some products 400 in the first row of products 410 are simultaneously located in the speed-changing section 220 and the auxiliary section 210, the acceleration of the speed-changing section 220 drives the first transmission roller 240 covered by the first row of products 410 to rotate faster, thereby causing the corresponding clutch 212 to control the first transmission roller 240 to disconnect from the transmission shaft 211; under the action of the first transmission roller 240 and the second transmission roller 221, the first row of products 410 can quickly reach the end of the speed-changing section 220, and the baffle 310 protrudes from the bearing surface 230 of the conveyor belt 200, so that the first row of products 410 can reach the end of the speed-changing section 220 quickly. The heads of the first row of products 410 are aligned; during this alignment process, the second row of products 420 and the third row of products 430 are both located in the auxiliary section 210, and the first transmission rollers 240 corresponding to the second row of products 420 and the third row of products 430 maintain their original rotational speed; after the first row of products 410 is aligned, the speed change section 220 returns to the starting speed, the clutch 212 connects the first transmission roller 240 and the transmission shaft 211, the baffle 310 descends below the bearing surface 230 of the conveyor belt 200, and the first row of products 410 is driven from the speed change section 220 to the transmission section 270.

[0058] The second aspect of this utility model provides a roller kiln, including a conveying component, a kiln body 600, and a high-efficiency transmission device for a roller kiln according to any of the first aspects of the present invention.
