Description

Technical Field

[0001] This utility model belongs to the technical field of pusher kiln structure, and more specifically, it relates to a pusher kiln for automated continuous production. Background Technology

[0002] A pusher kiln is a continuous thermal processing equipment. Its core feature is that it uses a propulsion system to push kiln furniture (such as crucibles and saggers) carrying workpieces along a fixed track through multiple temperature-controlled zones, including preheating, heating, holding, and cooling, to achieve batch and standardized thermal processing of workpieces. It is widely used in ceramics, electronics, materials and other fields, and is especially suitable for industrial production scenarios with high requirements for heating uniformity and production continuity.

[0003] However, in actual production and operation, to further shorten the production cycle of pusher kilns and improve production efficiency, multiple rows of kiln furniture are usually operated in parallel. However, pusher kilns operating in parallel often experience irregular arrangement of saggers at the discharge end. This disordered state prevents the automated feeding and discharging systems from coordinating properly, and the automated robotic arms or conveying equipment cannot reliably grasp or receive irregularly positioned saggers, causing interruptions in the automated process. Therefore, frequent operator intervention is required, switching to manual mode. This human intervention not only disrupts the inherent automatic cycle rhythm of the pusher kiln, leading to production interruptions, but also causes the cycle shortening measures intended to improve efficiency to actually decrease the overall equipment utilization rate. Ultimately, the actual production efficiency of the kiln fails to increase with the shortened cycle, instead exhibiting a paradoxical situation of decline. This has become a key problem restricting further optimization and upgrading of pusher kiln technology. Utility Model Content

[0004] The purpose of this utility model is to provide an automated continuous production pusher kiln, which aims to solve the problem that existing pusher kilns cannot achieve synchronous conveying and discharge of multiple kiln furniture in the same row, resulting in low production efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An automated continuous production pusher kiln is provided, comprising a feeding device and a kiln body.

[0010] In one possible implementation, the cooling zone further includes a detection element that is communicatively or electrically connected to the cooling conveying assembly. When the detection element detects the cartridge, the cooling conveying assembly is activated and transports the cartridge.

[0011] In one possible implementation, the cooling conveying assembly is provided in multiple sets along the conveying direction, the detection element is provided in a one-to-one correspondence with the cooling conveying assembly, and the conveying speed of the multiple sets of cooling conveying assemblies gradually decreases along the conveying direction.

[0012] In one possible implementation, the heating zone is divided into a preheating section and a sintering section along the conveying direction, and the heating zone includes: A heating and conveying assembly, located within the preheating section and the sintering section, is used to convey the casing.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

In the claims, description, and accompanying drawings of this utility model, unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" should be interpreted broadly, that is, any connection method in which there is no displacement relationship or relative rotation relationship between the two, that is, including non-removable fixed connection, detachable fixed connection, integral connection, and fixed connection through other devices or elements. In the claims, description, and accompanying drawings of this utility model, the terms "comprising," "having," and their variations are intended to mean "including but not limited to."

[0021] Please refer to the following: Figures 1 to 6The pusher kiln for automated continuous production provided by this utility model will now be described. The automated continuous production pusher kiln includes a feeding device 1 and a kiln body. The kiln body includes a heating zone 2, a cooling zone 3, and a discharge zone 4 distributed along the conveying direction. The feeding device 1 is used to feed the casing 5 into the heating zone 2. The discharge zone 4 is divided into an adjustment section 401, a transition section 402, and a discharge section 403 along the conveying direction. The discharge zone 4 includes a discharge conveying assembly 404, an adjustment assembly 407, and a separating assembly. The discharge conveying assembly 404 covers the adjustment section 401, the transition section 402, and the discharge section 403, and transports the casing 5 along the conveying direction. The adjustment assembly 407 includes an adjustment element 4072, and a sensor 4071 and a timer respectively connected to the adjustment element 4072. When the sensor 4071 detects the casing 5, the adjustment element 4072 intercepts the casing 5, making multiple casings 5 ​​in the same row flush. The separating assembly is located above the discharge conveying assembly 404 and is used to isolate the discharge zone 4 from the outside.

[0022] The automated continuous production pusher kiln provided by this utility model, compared with the prior art, can automatically detect and intercept the advance-positioned box body 5 through the coordinated action of the sensor 4071, timer and adjustment component 4072 in the adjustment component 407. This ensures that multiple rows of box bodies 5 in the same row are accurately aligned and neatly arranged before entering the discharge section 403, providing stable and reliable gripping conditions for subsequent automated discharge equipment, thereby ensuring the continuity of the production process and the seamless connection of the automation system. A separator component is set above the discharge conveying component 404, which effectively isolates the discharge area 4 from the external environment, reduces temperature fluctuations and external interference, protects the quality of the box body 5 and the workpiece, and creates a stable working environment for adjustment operations. This structure enables the pusher kiln to maintain high equipment utilization when taking measures to shorten the production cycle, truly transforming cycle shortening into continuous improvement in production efficiency. It realizes the synchronous and neat conveying of multiple rows of box bodies 5 at the discharge end, effectively solving the bottleneck problem of automation process interruption and production efficiency decline caused by discharge disorder in traditional pusher kilns.

[0023] Work process: After the multi-row box bodies 5 carrying the workpieces are processed by the heating zone 2 and cooling zone 3, they enter the adjustment section 401 of the discharge zone 4. Here, the discharge conveying assembly 404 continuously transports the box bodies 5 forward. The sensor 4071 detects the position of the box bodies 5 in real time. When the sensor 4071 detects a box body 5, the signal is transmitted to the adjustment component 4072. The adjustment component 4072 then intercepts the leading box body 5 in that row, slowing its forward movement, while the other box bodies 5 continue to move forward. At the same time, the timer keeps a precise count. After the preset time is reached, the adjustment component 4072 resets according to the signal transmitted by the timer, ensuring that the interception time is sufficient for the box bodies 5 in the same row to align and continue moving forward. After the alignment and sorting in the adjustment section 401, the neatly arranged multi-row box bodies 5 enter the transition section 402 for final posture stabilization. Subsequently, the box bodies 5 enter the discharge section 403. At this time, they have maintained a neat queue and can be reliably and efficiently grasped and removed by the automatic robot or conveying equipment at the discharge end, realizing fully automated continuous discharge. Throughout the process, the separation components keep the material handling area isolated from the external environment, ensuring process stability and product quality.

[0024] Optionally, the adjusting member 4072 can be a telescopic component that extends and retracts in the vertical direction, such as a pneumatic or hydraulic telescopic component, which can intercept and release the casing 5 through its own extension and retraction. Of course, one end of the adjusting member 4072 can be connected to a motor, and the motor controls the rotation of one end of the adjusting member 4072, thereby achieving the interception and release of the casing 5.

[0025] Optionally, sensor 4071 can be an infrared sensor 4071 or a magnetic sensor 4071.

[0026] Optionally, the feeding device 1 is a mechanical structure that puts the box body 5 into the kiln body. It can be a robotic arm or a flat push assembly formed by multiple telescopic cylinders or telescopic hydraulic cylinders, as long as it can realize the conveying of the box body 5. This is not the point of invention of this application and will not be described in detail here.

[0027] In some embodiments, please refer to Figures 3 to 4The separation assembly includes a first separation mechanism 405 and a second separation mechanism 406. The first separation mechanism 405 includes a first gate 4051 and a first driver 4052 connected to the first gate 4051. It also includes a first opening member 4053 and a first closing member 4054, which are respectively communicatively connected to the first driver 4052. The first opening member 4053 is located in the adjustment section 401, and the first closing member 4054 is located in the transition section 402. Both the first opening member 4053 and the first closing member 4054 are used to sense the position of the housing 5. The first gate 4051 is located between the adjustment section 401 and the transition section 402 for separation. The adjustment section 401 and the transition section 402; the second separation mechanism 406 includes a second gate 4061 and a second driver 4062 connected to the second gate 4061, and also includes a second opening member 4063 and a second closing member 4064 respectively communicated with the second driver 4062. The second opening member 4063 is located in the transition section 402, and the second closing member 4064 is located in the discharge section 403. Both the second opening member 4063 and the second closing member 4064 are used to sense the position of the box body 5. The second gate 4061 is located between the transition section 402 and the discharge section 403 to separate the transition section 402 and the discharge section 403.

[0028] When the casing 5 is aligned and arranged within the adjustment section 401, the first gate 4051 is closed, isolating the adjustment section 401 from the transition section 402. As the aligned row of casings 5 ​​moves forward, it triggers the first opening element 4053 located within the adjustment section 401. The first actuator 4052 then drives the first gate 4051 to open, allowing the row of casings 5 ​​to enter the transition section 402. Once the row of casings 5 ​​passes through and triggers the first closing element 4054 within the transition section 402, the first gate 4051 immediately closes, thus maintaining the independence of each area. Subsequently, the casing 5 moves steadily within the transition section 402. When it triggers the second opening element 4063 within the transition section 402, the second actuator 4062 drives the second gate 4061 to open, allowing the casing 5 to enter the discharge section 403. Once the casing 5 triggers the second closing element 4064 within the discharge section 403, the second gate 4061 immediately closes. This cycle, through the sequential opening and closing of the two gates, not only achieves physical isolation, preventing a large amount of external air from entering the kiln when the box 5 is sent out of the discharge section 403, but also reduces the risk of material oxidation caused by a large amount of air entering the kiln.

[0029] Optionally, both the first driver 4052 and the second driver 4062 are telescopic components, such as pneumatic or hydraulic telescopic components, or they can be lead screws and motors connected to the lead screws.

[0030] Optionally, the discharge zone 4 is also equipped with an air inlet pipe and an air outlet pipe. The air inlet pipe is used to supply nitrogen into the discharge zone 4. The discharge zone 4 is equipped with a pressure detection device 303. When the pressure in the discharge zone 4 increases to a preset value due to air entering, the air outlet pipe will discharge the gas in the discharge zone 4, while the air inlet pipe supplies nitrogen into the discharge zone 4 to ensure the nitrogen concentration in the discharge zone 4.

[0031] Specifically, the first closing element 4054 is located upstream of the second opening element 4063, and the second gate 4061 opens after the first gate 4051 is closed when the distance between them is sufficient.

[0032] In some embodiments, please refer to Figure 3 The discharge conveying assembly 404 includes a receiving mechanism 4041 and a conveying mechanism 4042. The receiving mechanism 4041 is located in the adjustment section 401 and is used to receive the box body 5 discharged from the cooling zone 3. The conveying mechanism 4042 is located downstream of the receiving mechanism 4041 and covers the adjustment section 401, the transition section 402 and the discharge section 403. The conveying mechanism 4042 includes a conveying driver and a transmission support connected to the conveying driver. The conveying driver is used to control the start of the transmission support, and the transmission support is used to send the box body 5 out of the discharge section 403.

[0033] The unpowered receiving mechanism 4041, located at the entrance of the adjustment section 401, not only smoothly receives the box bodies 5 from the cooling zone 3, but also utilizes its free-rolling characteristic to allow subsequent box bodies 5 to move smoothly forward on the unpowered rollers and gently push the front row of box bodies 5 when the previous row of kilns is paused on the receiving mechanism 4041. This eliminates the tiny gaps between the box bodies 5, allowing the box bodies 5 in the same row to come close together and naturally achieve lateral alignment at the outlet gate, improving the reliability and efficiency of the alignment effect. The box bodies 5 pushed to the conveying mechanism 4042 continue to move forward neatly under the action of the conveying support.

[0034] Optionally, the conveying speed of the transmission support is greater than the conveying speed of the power mechanism 2032 in the cooling zone 3, thereby separating the two rows of closely fitted box bodies 5 to avoid interference when passing through the gate.

[0035] Optionally, the transmission support may include multiple rollers arranged along the conveying direction, and the transmission drive includes a conveyor belt wound around the multiple rollers and a motor connected to the conveyor belt. The motor drives one of the rollers to rotate, thereby controlling the rotation of multiple rollers through the conveyor belt. The axis of the rollers is perpendicular to the conveying direction. Optionally, the receiving mechanism 4041 includes multiple rollers, which are rotatably connected to the frame. The frame is a support structure located inside the kiln.

[0036] In some embodiments, please refer to Figures 1 to 2 ,and Figure 6 The cooling zone 3 includes a cooling conveying assembly 302 and an air supply assembly 301. The cooling conveying assembly 302 is used to convey the box 5 along the conveying direction. The air supply assembly 301 is located above the cooling conveying assembly 302. The air supply assembly 301 includes a conveying pipe and an air pump on the conveying pipe. The conveying pipe is used to supply protective gas into the cooling zone 3 to prevent the sintered material from oxidizing.

[0037] The air supply component 301 accurately delivers inert gas to the cooling zone 3 space via a delivery pipe through an air pump. When the box 5 and the high-temperature sintered material it carries enter the cooling stage, it can quickly form an air-isolated inert gas atmosphere around it, blocking the material from contacting oxygen. This effectively prevents the surface deterioration, compositional changes, or performance degradation of the high-temperature material due to oxidation during the cooling process, ensuring the high yield of the product.

[0038] Optionally, the protective gas can be nitrogen.

[0039] In some embodiments, please refer to Figure 6 The cooling conveying assembly 302 includes a conveying mechanism 3021 and a driving mechanism 3022. The conveying mechanism 3021 includes multiple transmission rollers distributed along the conveying direction and a conveyor belt wrapped around the outer periphery of the multiple transmission rollers. The driving mechanism 3022 includes a third driver and a reducer connected to the third driver. The reducer is connected to one or more of the transmission rollers and drives the transmission rollers to rotate around their own axes.

[0040] Multiple transmission rollers are evenly distributed along the conveying direction, and power is transmitted through the conveyor belt. This allows the housing 5 to pass smoothly through the multiple transmission rollers during the conveying process, effectively preventing the housing 5 from shifting position or tipping over during cooling and conveying, and ensuring the continuity of the cooling process. The third drive provides a stable power source, while the reducer can reduce the driving force and increase the torque as needed, ensuring that the transmission rollers drive the conveyor belt at a smooth and controllable speed. When a transmission roller or the conveyor belt malfunctions, it can be disassembled and repaired individually without disassembling the entire drive mechanism 3022.

[0041] In some embodiments, please refer to Figure 2 The cooling zone 3 also includes a detection element 303, which is communicatively or electrically connected to the cooling conveying assembly 302. When the detection element 303 detects the case 5, the cooling conveying assembly 302 opens and transports the case 5.

[0042] When the detection element 303 detects the presence of the casing 5 and generates a trigger signal, this signal is quickly transmitted to the control unit of the cooling conveying assembly 302 via a communication link or conductive line. Upon receiving the signal, the control unit rapidly starts the cooling conveying assembly 302, smoothly receiving and conveying the casing 5 to the subsequent cooling station in the cooling zone 3. Once the casing 5 has completely left the monitoring range of the detection element 303, or when the detection element 303 has not detected a new casing 5 for a continuous period, the cooling conveying assembly 302 can automatically stop operating according to a preset program, waiting for the next trigger signal from the detection element 303, thus achieving automated start-stop cycles for the conveying of the casing 5. This embodiment significantly improves the automation level of the cooling process in the pusher kiln, reduces human error, and precisely matches the cooling conveying rhythm with the kiln exit rhythm of the preceding heat treatment stage, further improving the continuity and efficiency of the overall production of the pusher kiln, making it particularly suitable for large-scale, high-cycle production scenarios.

[0043] Optionally, the detection element 303 can be an infrared detector or a magnetic detector.

[0044] In some embodiments, please refer to Figure 1 The cooling conveying assembly 302 is provided with multiple sets along the conveying direction, and the detection element 303 is set one-to-one with the cooling conveying assembly 302. The conveying speed of the multiple sets of cooling conveying assemblies 302 gradually decreases along the conveying direction. This embodiment effectively avoids the accumulation or blockage of the casing 5 at the entrance of the cooling zone 3 due to sudden changes in material flow speed by subjecting the casing 5 to a gradual deceleration process after entering the cooling zone 3. This gradient speed setting ensures that the casing 5 exiting the high-temperature heating zone 2 can smoothly and promptly enter the cooling zone 3, thereby maintaining the continuity and stability of the material flow from heating to cooling in the entire pusher kiln and preventing production interruptions caused by blockage at the entrance of the cooling zone 3. At the same time, the gradually decreasing conveying speed extends the residence time of the casing 5 in the cooling zone 3, providing the workpiece with more sufficient and uniform heat dissipation time. This facilitates a smoother and more controllable cooling curve, not only improving the cooling quality of the product and reducing thermal stress damage caused by rapid cooling, but also making the protection effect of the inert gas injected by the gas supply component 301 more thorough.

[0045] In some embodiments, please refer to Figures 1 to 2 The heating zone 2 is divided into a preheating section 201 and a sintering section 202 along the conveying direction. The heating zone 2 includes a heating conveying assembly 203, a first heating element 204, and a second heating element. The heating conveying assembly 203 is located in the preheating section 201 and the sintering section 202 and is used to convey the box body 5. The first heating element 204 is located in the preheating section 201. The second heating element is located in the sintering section 202. The temperature of the preheating section 201 is lower than the temperature of the sintering section 202.

[0046] Before entering the high-temperature sintering section 202, the casing 5 undergoes a relatively low-temperature and uniform preheating process in the preheating section 201. This effectively removes moisture and organic binders from the blank and ensures a uniform temperature rise within it, thus greatly preventing defects such as surface cracking, deformation, or internal stress concentration caused by direct entry into the high-temperature zone. The independent second heating element ensures that the sintering section 202 can quickly reach and precisely maintain the maximum temperature required by the process, providing a sufficient and stable thermal environment for the solidification and densification of the material. This embodiment not only significantly improves the sintering quality and consistency of the product but also effectively prevents a decrease in yield due to excessively rapid heating. Simultaneously, the independent temperature control design of the separate temperature zones optimizes thermal energy utilization efficiency and avoids energy waste.

[0047] Specifically, the temperature of the preheating section 201 is ≤850℃, and the temperature of the sintering section 202 is 850-1150℃. In some embodiments, please refer to Figures 1 to 2 ,and Figure 5 The heating zone 2 also includes a first temperature detector located in the preheating section 201 and a second temperature detector located in the sintering section 202. The first temperature detector is electrically or communicatively connected to the first heating element 204, and the second temperature detector is electrically or communicatively connected to the second heating element. This solution monitors the temperature separately for both the preheating and sintering stages. When the first temperature detector detects that the temperature in the preheating section 201 is higher than the preheating temperature, it controls the first heating element 204 to reduce its heating power; conversely, it controls the first heating element 204 to increase its heating power. Similarly, the second temperature detector and the second heating element operate accordingly. This precise temperature control effectively prevents cracking of the workpiece when it enters the sintering section 202 due to insufficient preheating, or affects the consistency of the final product performance due to sintering temperature fluctuations. It ensures that each batch of workpieces undergoes the exact same thermal curve, greatly improving the uniformity and stability of product quality. At the same time, closed-loop control avoids excessive energy consumption, achieving high efficiency and energy saving in the heating process.

[0048] In some embodiments, please refer to Figure 5 The heating and conveying assembly 203 includes a conveying mechanism 2031 and a power mechanism 2032. The conveying mechanism 2031 includes a plurality of guide rollers arranged along the conveying direction and a conveyor belt wrapped around the plurality of guide rollers. It also includes support wheels. Each guide roller is fitted with a plurality of spaced support wheels along its own axial direction. The axis of the guide roller is perpendicular to the conveying direction. The support wheels are used to support the housing 5. The power mechanism 2032 is connected to one or more of the guide rollers and is used to drive the guide rollers to rotate around their own axis.

[0049] By using multiple support rollers spaced axially by the guide rollers, the weight of the box 5 is distributed to multiple discrete support points, reducing the contact area of ​​the box 5. This effectively reduces the risk of adhesion or friction damage to the box 5 under high temperature conditions, ensuring the integrity of the box 5 and the workpiece.

[0050] Specifically, the support wheel is a high-temperature resistant component.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
