Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic machinery technology, and in particular to an integrated stacking and unloading machine suitable for conveying double-layer saggers. Background Technology
[0002] In rare earth mineral smelting and separation projects, roller-bar tunnel furnaces are frequently used to smelt rare earth minerals. Due to the special nature of roller-bar tunnel furnaces and to meet energy conservation and emission reduction requirements, powdered products are transferred through diamond saggers and placed on rollers. The continuous rotation of the rollers propels the fired products forward sequentially. Once ignited and opened, operation generally continues uninterrupted, requiring continuous loading and unloading of products. To fully utilize smelting resources, companies typically use double-layer saggers for loading and smelting. This necessitates double-layer stacking of the saggers after each loading and smelting of products, and also requires additional processing after firing. Unloading is required to meet the loading and unloading process of each sagger. Since the firing temperature inside the roller tunnel furnace is as high as 1400 degrees Celsius or more, the temperature of the sagger is still as high as 90 degrees Celsius after it is cooled and exited the kiln. It is still in a high-temperature state on the circulating roller conveyor outside the kiln, resulting in a harsh working environment. In addition, each sagger with material weighs nearly 15 kilograms, and the labor intensity of stacking and unloading is high. In addition, the equipment operates continuously, and workers cannot work continuously for a long time. They need to be frequently moved and relieved of heat. In severe cases, they are prone to heatstroke and fainting. Therefore, a mechanism is needed to replace the current manual operation to meet the requirements of automated production. Summary of the Invention
[0003] The purpose of this utility model is to provide a stacking and unloading integrated machine for conveying double-layer crucibles, which saves manpower, reduces operating effort, is highly efficient, and can continuously and automatically stack and unload crucibles.
[0004] The present invention relates to a stacking and unloading integrated machine for double-layer crucible conveying, which is implemented as follows: it includes a conveyor line and a crucible clamping and lifting mechanism set on the conveyor line. The special feature is that there are two sets of crucible clamping and lifting mechanisms, which are set one in front of the other on the conveyor line. The crucible clamping and lifting mechanism includes a lifting mechanism set below the conveyor line, a baffle mechanism in front of the lifting mechanism, a centering mechanism set above the conveyor line and matched with the lifting mechanism, and a claw clamping mechanism set at the top of the conveyor line and matched with the lifting mechanism. A claw clamping base is set above the conveyor line, and the claw clamping mechanism is set on the claw clamping base. A crucible sensor is set at the crucible clamping and lifting mechanism.
[0005] When crucibles are stacked, the previous crucible is conveyed to the front crucible clamping and lifting mechanism via the conveyor line. The front crucible sensor detects the previous crucible's arrival, and the control device raises the baffle of the front crucible clamping and lifting mechanism, stopping the previous crucible on the conveyor line. The lifting mechanism of the front crucible clamping and lifting mechanism then lifts the previous crucible away from the conveyor line. The centering mechanism of the front crucible clamping and lifting mechanism centers the lifted crucible, then resets. The jaw mechanism of the front crucible clamping and lifting mechanism picks up the crucible and lifts it above the height of the previous crucible. The lifting mechanism of the front crucible clamping and lifting mechanism resets. The next crucible is then conveyed to the next crucible clamping and lifting mechanism via the conveyor line. The next crucible sensor detects the next crucible's arrival, and the control device raises the baffle of the next crucible clamping and lifting mechanism, stopping the next crucible on the conveyor line. The next crucible clamping and lifting mechanism... The lifting mechanism lifts the next sagger away from the conveyor line. The centering mechanism of the rear sagger clamping lifting mechanism centers the lifted sagger. The claw mechanism of the rear sagger clamping lifting mechanism grabs the sagger. The centering mechanism and lifting mechanism of the rear sagger clamping lifting mechanism reset. After the bottom plate is conveyed to the rear sagger clamping lifting mechanism and stopped by the baffle of the rear sagger clamping lifting mechanism, the claw mechanism of the rear sagger clamping lifting mechanism descends and places the sagger on the bottom plate. The baffle mechanism of the rear sagger clamping lifting mechanism resets. The sagger and the bottom plate are conveyed by the conveyor line to the front sagger clamping lifting mechanism. After being stopped by the baffle of the front sagger clamping lifting mechanism, the claw mechanism of the front sagger clamping lifting mechanism descends and places the front sagger on the sagger. The baffle mechanism of the rear sagger clamping lifting mechanism resets. The conveyor line conveys the two saggers stacked on the bottom plate to the firing and smelting process.
[0006] When separating the saggers, the conveyor line delivers the stacked saggers to the rear sagger clamping and lifting mechanism. The rear sagger sensor detects the saggers are in position, and the control device raises the baffle of the rear sagger clamping and lifting mechanism, stopping the stacked saggers on the conveyor line. The control device then controls the lifting mechanism of the rear sagger clamping and lifting mechanism to lift the stacked saggers away from the conveyor line. The centering mechanism of the rear sagger clamping and lifting mechanism centers the lifted saggers, then resets. The claw mechanism of the rear sagger clamping and lifting mechanism grabs the upper sagger and lifts it away from the lower sagger. The lifting mechanism of the rear sagger clamping and lifting mechanism resets, and the baffle mechanism resets. The lower sagger, along with its base plate, is then conveyed to the front sagger clamping and lifting mechanism. The front sagger sensor detects the lower sagger... Once the base plate is in place, the control device raises the baffle of the front sagger clamping and lifting mechanism, stopping the sagger and base plate on the conveyor line. The control device then raises the lifting mechanism of the front sagger clamping and lifting mechanism, lifting the sagger and base plate away from the conveyor line. The centering mechanism of the front sagger clamping and lifting mechanism centers the next sagger after it has been raised, and the jaw mechanism of the front sagger clamping and lifting mechanism grabs the lower sagger. The centering mechanism and lifting mechanism of the front sagger clamping and lifting mechanism reset, and the baffle mechanism of the front sagger clamping and lifting mechanism resets. After the base plate has been conveyed a certain distance by the conveyor line, the jaw mechanism of the rear sagger clamping and lifting mechanism lowers, placing the upper sagger on the conveyor line. At the same time, the jaw mechanism of the front sagger clamping and lifting mechanism lowers, placing the lower sagger on the conveyor line. The conveyor line then transports the two separated saggers and the base plate to the dumping process.
[0007] Compared with existing technologies, this invention has the advantages of saving manpower, reducing operating effort, increasing efficiency, and enabling continuous automatic stacking and unloading of saggers. Attached Figure Description

Detailed Implementation
[0013] The present invention, with reference to the accompanying drawings and embodiments, provides a more detailed description of the stacking and unloading integrated machine applicable to double-layer crucible conveying:
[0014] like Figure 1 , 2 As shown, the stacking and unloading integrated machine for double-layer crucible conveying of this utility model is implemented as follows: it includes a conveyor line 1 (roller conveyor line) and a crucible clamping and lifting mechanism A set on the conveyor line 1. The special feature is that there are two sets of crucible clamping and lifting mechanisms A, which are set one in front of the other on the conveyor line 1. The crucible clamping and lifting mechanism A includes a lifting mechanism 2 set below the conveyor line 1, a baffle mechanism 3 located in front of the lifting mechanism 2, a centering mechanism 4 set on the conveyor line 1 that matches the position of the lifting mechanism 2, and a claw clamping mechanism 5 set at the top of the conveyor line 1 that matches the lifting mechanism 2. A claw clamping base 6 is set on the conveyor line 1, and the claw clamping mechanism 5 is set on the claw clamping base 6. A crucible sensor 7 is set at the crucible clamping and lifting mechanism A.
[0015] Preferably, the lifting mechanism 2 includes a lifting pneumatic mechanism 201 disposed on the transmission line 1 and a lifting platform 202 driven by the lifting pneumatic mechanism 201 to move up and down. The lifting pneumatic mechanism 201 drives the lifting platform 202 to move up and down, causing the sagger B to leave the transmission line 1 or fall back onto the transmission line 1.
[0016] Preferably, the baffle mechanism 3 includes a baffle pneumatic mechanism 301 disposed on the transmission line 1 and located in front of the lifting mechanism 2, and a baffle 302 driven by the baffle pneumatic mechanism 301 to move up and down. The baffle pneumatic mechanism 301 drives the baffle 302 to rise above the transmission line 1 or fall below the conveyor line 1 to block and position or release the sagger B or the base plate C.
[0017] Preferably, the centering mechanism 4 includes four centering pneumatic mechanisms 401 arranged on the transmission line 1 and distributed around the four corners of the lifting mechanism 2, and a pair of rollers 402 driven by the centering pneumatic mechanisms 401 to move laterally back and forth. The four centering pneumatic mechanisms 401 operate simultaneously, driving their respective pair of rollers 402 to move towards or away from the sagger B, thereby achieving the technical effect of centering the sagger B.
[0018] Preferably, the claw mechanism 5 includes a vertically moving pneumatic mechanism 501 disposed on the claw base 6, and four claws 502 driven by the vertically moving pneumatic mechanism 501 to move vertically. Each claw 502 is oscillatingly disposed on the claw seat 503. The piston rod of the claw pneumatic mechanism 504 drives the four claws 502 to oscillate synchronously, so that the claw heads of the four claws 502 approach or leave the sagger B.
[0019] Preferably, a row of guide rollers 9 is provided on the side of the conveyor line 1 so that the base plate C can be guided forward by the guide rollers 9.
[0020] like Figure 3As shown, when the saggers B are stacked, the previous sagger B is conveyed to the rear sagger clamping and lifting mechanism A by the conveyor line 1. The rear sagger sensor 7 senses that the previous sagger B has reached its position. The control device 8 controls the baffle 302 of the baffle mechanism 3 of the rear sagger clamping and lifting mechanism A to rise, stopping the previous sagger B on the conveyor line 1. The lifting mechanism 2 of the rear sagger clamping and lifting mechanism A lifts the previous sagger B away from the conveyor line 1. The centering mechanism 4 of the rear sagger clamping and lifting mechanism A centers the lifted sagger B. The centering mechanism 4 of the rear sagger clamping and lifting mechanism A resets, and the rear sagger clamping and lifting mechanism resumes operation. The jaw gripper mechanism 5 of mechanism A picks up the previous saucer B and lifts it above the height of a saucer. The lifting mechanism 2 of the rear saucer clamping and lifting mechanism A resets, as does the baffle mechanism 3 of the rear saucer clamping and lifting mechanism A. The next saucer B is then conveyed by conveyor line 1, passing under the previous saucer B, and arrives at the front saucer clamping and lifting mechanism A. Simultaneously, the baffle 302 of the baffle mechanism 3 of the rear saucer clamping and lifting mechanism A rises. The front saucer sensor 7 senses the arrival of the next saucer B, and the control device 8 controls the baffle 302 of the baffle mechanism 3 of the front saucer clamping and lifting mechanism A to rise, thus... The next saucer B stops on conveyor line 1. The lifting mechanism 2 of the front saucer clamping and lifting mechanism A lifts the next saucer B away from conveyor line 1. The centering mechanism 4 of the front saucer clamping and lifting mechanism A centers the lifted next saucer B. The claw mechanism 5 of the front saucer clamping and lifting mechanism A picks up the next saucer B and lifts it above the height of a saucer. The centering mechanism 4 and the lifting mechanism 2 of the front saucer clamping and lifting mechanism A reset. At this time, the bottom plate C is conveyed to the rear saucer clamping and lifting mechanism A and is stopped by the baffle 302 of the rear saucer clamping and lifting mechanism A. The jaw mechanism 5 of the sagger-lifting mechanism A descends, placing the previous sagger B on the base plate C. The baffle mechanism 3 of the rear sagger-lifting mechanism A resets. The previous sagger B and the base plate C are conveyed to the front sagger-lifting mechanism A by the conveyor line 1. After being stopped by the baffle 302 of the front sagger-lifting mechanism A, the jaw mechanism 5 of the front sagger-lifting mechanism A descends, placing the rear sagger B on the previous sagger B. The baffle mechanism A of the rear sagger-lifting mechanism A resets. The conveyor line 1 conveys the two saggers B stacked on the base plate C to the firing and smelting process.
[0021] like Figure 4As shown, when separating the sagger B, the conveyor line 1 delivers the stacked sagger D to the rear sagger clamping and lifting mechanism A. The rear sagger sensor 7 senses that the stacked sagger D has reached its position. The control device 8 controls the baffle 302 of the baffle mechanism 3 of the rear sagger clamping and lifting mechanism A to rise, stopping the stacked sagger D on the conveyor line 1. The control device 8 then controls the lifting mechanism 2 of the rear sagger clamping and lifting mechanism A to lift the stacked sagger D away from the conveyor line 1. The centering mechanism of the rear sagger clamping and lifting mechanism A... After being lifted, the stacked saggers D are aligned. The alignment mechanism 4 of the rear sagger clamping and lifting mechanism A is reset. The claw mechanism 5 of the rear sagger clamping and lifting mechanism A picks up the upper sagger B of the stacked sagger D and lifts it away from the lower sagger B. The lifting mechanism 2 of the rear sagger clamping and lifting mechanism A is reset. The baffle mechanism 3 of the rear sagger clamping and lifting mechanism A is reset. The lower sagger B, together with the base plate C, is transported by the conveyor line to the front sagger clamping and lifting mechanism A. The front sagger sensor 7 senses the connection between the lower sagger B and the base plate C. When the base plate C is in position, the control device 8 controls the baffle 302 of the baffle mechanism 3 of the front sagger clamping and lifting mechanism A to rise, so that the sagger B along with the base plate C stops on the conveyor line 1. The control device 8 controls the lifting mechanism 2 of the front sagger clamping and lifting mechanism A to lift the lower sagger B along with the base plate C away from the conveyor line 1. The centering mechanism 4 of the front sagger clamping and lifting mechanism A centers the next sagger B after it has been lifted. The claw mechanism 5 of the front sagger clamping and lifting mechanism A grasps the lower sagger B. The centering mechanism 4 and lifting mechanism 2 of the sagger clamping and lifting mechanism A are reset, and the baffle mechanism 3 of the front sagger clamping and lifting mechanism A is reset. After the bottom plate C is conveyed a certain distance by the conveyor line 1, the claw mechanism 5 of the rear sagger clamping and lifting mechanism A is lowered to place the upper sagger B on the conveyor line 1. At the same time, the claw mechanism 5 of the front sagger clamping and lifting mechanism A is lowered to place the lower sagger B on the conveyor line 1. The conveyor line 1 conveys the two separated saggers B and the bottom plate C to the dumping process.
