Description

Technical Field

[0001] This application relates to the field of lithium battery material production technology, and in particular to a furnace transfer machine. Background Technology

[0002] The automatic circulation line for lithium battery kilns is an automated production line used for loading and unloading positive and negative materials in lithium battery kilns. The automatic circulation line for lithium battery kilns includes an automatic sagger loading machine, a dual-station shaking machine, a meshing machine, a stacking machine, an inlet and outlet transfer machine, an integrated sagger breaking machine, a fully sealed sagger turning and unloading machine, ceramic wheel conveying equipment, and a control unit. The inlet transfer machine is used to transport the saggers to the kiln inlet.

[0003] For example, Chinese Patent Publication No. CN213631588U describes a sealed furnace inlet transfer machine for an automatic circulation line on the outer rail of a kiln. This device has the following shortcomings:

[0004] The aforementioned device uses multiple sprockets and drive rollers to transport the saggers laterally. However, the use of multiple sprockets and drive rollers makes the installation process more complex and the production cost higher. It also causes damage to the saggers during transportation. Furthermore, the lifting mechanism of the aforementioned device uses multiple bidirectional cylinders to lift each sagger individually because the previous kiln firing process was insufficient and required a certain gap between the saggers. After the kiln process is upgraded, it is no longer necessary to lift the saggers individually, so the device needs to be further simplified to reduce costs. Utility Model Content

[0005] To address the issues of complex installation and high production costs, this application provides a furnace transfer machine.

[0006] The furnace-feeding transplanting machine provided in this application adopts the following technical solution:

[0007] A furnace-feeding transplanting machine includes a frame and a sagger filled with materials, the frame including a top frame and a bottom frame fixedly connected to the bottom of the top frame;

[0008] The push-pull mechanism is used to push the sagger toward the kiln inlet;

[0009] The transverse conveyor mechanism is used to transport the sagger into the machine frame;

[0010] The lifting frame mechanism is used to lift the conveying sagger;

[0011] The rack and pinion synchronous lifting mechanism is used to drive the movement of the lifting frame mechanism;

[0012] The transverse conveying mechanism includes two connecting rods fixedly connected to the inner side of the bottom frame. Two aluminum profiles are fixedly installed on the top surface of the two connecting rods. Connecting frames that are rotatably connected to the conveying gear are fixedly installed at both ends of the aluminum profiles. A speed-multiplying chain for transmission is meshed on the surface of the conveying gear. A second motor for driving the conveying gear to rotate is installed below one end of the aluminum profile.

[0013] The lifting frame mechanism includes a lifting fixing frame disposed inside the bottom frame. The top of the lifting fixing frame is provided with a plurality of roller sets II. The bottom of the lifting fixing frame is fixedly provided with a support plate I and a support plate II for supporting the lifting fixing frame.

[0014] The rack and pinion synchronous lifting mechanism includes a support frame fixedly connected to the bottom of the inner side of the bottom frame. A mounting plate fixedly connected to the bottom of the lifting cylinder is fixedly installed in the middle of the top surface of the support frame. Four rack and pinion lifters are fixedly installed on the surface of the support frame. A connecting shaft is provided between two adjacent rack and pinion lifters. A third motor for driving the rack and pinion lifters is fixedly installed on the top of the support frame.

[0015] By adopting the above technical solution, the saggers can be transported into the machine frame through the transverse conveying mechanism. The saggers are transported using aluminum profiles, conveying gears, and double-speed chains meshing with the conveying gears. This saves material costs and simplifies the installation process without affecting the operation of the device. The double-speed chains and saggers are stored together, which will not cause wear to the saggers. The rack and pinion synchronous lifting mechanism and the lifting frame mechanism can lift the saggers transported into the machine frame at the same time, making it easy for the push-pull mechanism to push the saggers together to the kiln inlet. The lifting is carried out with the assistance of a separate lifting cylinder and a rack and pinion lifting machine, which reduces the number of cylinders and greatly saves costs.

[0016] Preferably, the aluminum profile is H-shaped, and a guide block for tensioning the speed-multiplying chain is fixedly provided on the inner side of the connecting frame. The surface of the speed-multiplying chain is close to the inner side of the aluminum profile with a gap.

[0017] By adopting the above technical solution, the H-shaped structure of the aluminum profile allows the double-speed chain to be well housed inside the aluminum profile, further reducing the gap between the upper and lower sections of the double-speed chain.

[0018] Preferably, the guide block abuts against the surface of the speed-doubler chain.

[0019] By adopting the above technical solution, the guide block can provide good tension to the chain of the double speed chain, so that the chain of the double speed chain and the conveying gear can work together better.

[0020] Preferably, the second motor is fixedly connected to one side of the bottom frame near the bottom frame, and a gearbox is provided at the output end of the second motor. The output end of the gearbox is fixedly connected to two conveying gears.

[0021] By adopting the above technology, the output end of the second motor can drive the conveying gear to rotate through the gearbox, thereby driving the double-speed chain to move.

[0022] Preferably, a floating joint is fixedly provided at the top of the lifting cylinder output.

[0023] By adopting the above technical solution and setting a floating joint, the output end of the lifting cylinder can be protected, and the service life of the lifting cylinder can be extended.

[0024] Preferably, the bottom of the support plate has a mounting hole for connecting the floating joint.

[0025] By adopting the above technical solution, the support plate and the floating joint can be fixed by nuts through the mounting holes.

[0026] Preferably, the roller assembly two is provided with a plurality of rollers four, the surface of which abuts against the bottom of the sagger.

[0027] By adopting the above technical solution, multiple rollers are set up to support the sagger, so as to facilitate the movement of the sagger.

[0028] Preferably, the bottom of the sagger abuts against the surface of the speed-doubler chain.

[0029] By adopting the above technical solution, the sagger can be transported along the double-speed chain.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] The lateral conveying mechanism allows the saggers to be transported into the machine frame. Aluminum profiles, conveying gears, and a double-speed chain meshing with the conveying gears are used to transport the saggers. This saves material costs and simplifies the installation process without affecting the operation of the equipment. The double-speed chain and the saggers are stored together, preventing wear on the saggers. The rack and pinion synchronous lifting mechanism and the lifting frame mechanism can simultaneously lift the saggers transported into the machine frame, making it easy for the push-pull mechanism to push the saggers together to the kiln inlet. The lifting is carried out using a separate lifting cylinder and the rack and pinion lifting machine, reducing the number of cylinders and greatly saving costs. Attached Figure Description

[0046] 6. Sagger. Detailed Implementation

[0047] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0048] Example 1

[0049] This application discloses a furnace transfer machine.

[0050] Reference Figures 1-3 A furnace-feeding transfer machine includes a frame 1 and a sagger 6 filled with materials. The frame 1 includes a top frame 11, the bottom of which is fixedly connected to the top of a bottom frame 12. Multiple rollers 13 are symmetrically arranged on the top inner side of the bottom frame 12 to guide the direction of conveying the sagger 6 and prevent the sagger 6 from colliding with the interior of the frame 1. Multiple roller groups 14 are arranged on the top of the bottom frame 12 near the kiln. Each roller group 14 includes at least three rollers 141. Dustproof boxes are symmetrically arranged on both sides of the frame 1 to prevent dust from falling onto the transverse conveying mechanism 3 and affecting its use. The outer surface of the frame 1 is covered with sheet metal and has multiple glass windows to observe the movement of the internal mechanism. A notch is provided at the bottom of the top frame 11 near the kiln to facilitate the conveying of the sagger 6 from the interior of the frame 1 to the kiln entrance.

[0051] In use, first install the push-pull mechanism 2 inside the top frame 11, install roller 13 on the top inside the bottom frame 12, then install roller group 14 on the top of the bottom frame 12 near the kiln, install the rack and pinion synchronous lifting mechanism 5 on the bottom inside the bottom frame 12, then install the lifting frame mechanism 4 above the rack and pinion synchronous lifting mechanism 5, install the transverse conveying mechanism 3 inside the bottom frame 12, and finally install the bottom of the top frame 11 onto the bottom frame 12. When transporting the sagger 6, the roller 13 can guide the sagger 6 well. Finally, when it is moved out of the machine frame 1, the roller 2 141 can reduce the friction, making it easier to move the sagger 6 out.

[0052] Reference Figures 3-4The push-pull mechanism 2 is used to push the sagger 6 inside the frame 1 toward the kiln inlet. The push-pull mechanism 2 includes a slide rail 25 fixedly installed inside the top frame 11. The surface of the slide rail 25 is slidably connected to the push-pull frame 24. The slide rail 25 can provide good support for the push-pull frame 24. A synchronous belt pulley assembly 21 is installed above the push-pull frame 24. The synchronous belt pulley assembly 21 includes two synchronous gears 212 rotatably installed on the top of the inner side of the top frame 11. A synchronous belt 211 is sleeved on the surface of the two synchronous gears 212. The inner side of the synchronous belt 211 is provided with teeth. The teeth of the synchronous belt 211 mesh with the teeth of the synchronous gear 212. The lower surface of the synchronous belt 211 is fixedly connected to the top of the push-pull frame 24 on the side near the kiln. A first motor 22 is fixedly installed on the side of the top frame 11 away from the kiln. The output end of the first motor 22 is coaxially fixedly connected to a synchronous gear 212, which can drive the synchronous gear 212 to rotate. The bottom of the push-pull frame 24 is fixedly connected to the side of the push-pull plate 23 near the push-pull frame 24 on the side near the push-pull frame 24, so that the push-pull frame 24 can move on the slide rail 25.

[0053] When in use, the first motor 22 is turned on, and the output end of the first motor 22 drives the synchronous gear 212 to rotate. The synchronous gear 212 meshes with the synchronous belt 211, thereby driving the synchronous belt 211 to move. The movement of the synchronous belt 211 further causes the push-pull frame 24 to slide on the slide rail 25. At the same time, the push-pull plate 23 moves synchronously with the push-pull frame 24. The push-pull plate 23 will push the sagger 6 and cause the sagger 6 to move towards the kiln inlet.

[0054] Reference Figure 1 , Figure 5 and Figure 9 The transverse conveying mechanism 3 is used to convey the sagger 6 into the machine frame 1. The transverse conveying mechanism 3 includes two connecting rods 38 fixedly connected to the upper inner side of the bottom frame 12. The bottom of two aluminum profiles 34 is fixedly connected to the top of the connecting rods 38, making the overall structure of the transverse conveying mechanism 3 more stable and robust. The aluminum profiles 34 are produced by extrusion, resulting in a hollow cavity structure inside the aluminum profiles 34. The aluminum profiles 34 have a hollow structure in the middle. The upper and lower parts of the aluminum profiles 34 are provided with sliding grooves to facilitate the limiting of the double-speed chain 33. The double-speed chain 33 is a chain structure with the first and second parts connected. 4. The bottom frame 12 extends out to both sides of the two ends, making it easier to place the sagger 6 onto the speed-doubler chain 33 from the outside. The outer sides of the two ends of the aluminum profile 34 are fixedly connected to the inner side of the connecting frame 35. The inner side of the connecting frame 35 is rotatably equipped with a conveying gear 32. The teeth of the two conveying gears 32 mesh with the chain structure of the speed-doubler chain 33, so that the speed-doubler chain 33 and the two conveying gears 32 form a whole. The upper half of the chain of the speed-doubler chain 33 is stored in the upper cavity of the aluminum profile 34. The chain surface of the speed-doubler chain 33 is higher than the highest point of the aluminum profile 34, so that the movement of the sagger 6 on the speed-doubler chain 33 is not obstructed.

[0055] The side of the connecting frame 35 near the guide block 36 is fixedly connected to the side of the guide block 36 near the connecting frame 35. The guide block 36 is a quarter-cylinder structure with a groove on its arc surface. The inner side of the groove of the guide block 36 is slidably connected to the wheel of the double-speed chain 33. The groove surface of the guide block 36 is smoothly connected to the inner bottom surface of the lower cavity of the aluminum profile 34, thereby changing the direction of movement of the double-speed chain 33 below the aluminum profile 34 and allowing it to enter the lower cavity of the aluminum profile 34. The wheel of the double-speed chain 33 located in the inner cavity of the aluminum profile 34 abuts against the bottom surface of the groove, reducing the distance between the upper and lower chains of the double-speed chain 33 without... To prevent the use of the speed-multiplying chain 33, the side of roller 37 near the connecting frame 35 is rotatably connected to the side of the connecting frame 35 near roller 37. The surface of roller 37 is higher than the surface of the speed-multiplying chain 33, so that roller 37 can assist the casket 6 in moving into or out of the surface of the speed-multiplying chain 33. The mounting end of the second motor 31 is fixedly connected to the side of the bottom frame 12 near the second motor 31. The output end of the second motor 31 is fixedly connected to the input end of gearbox 39. The output end of gearbox 39 is coaxially fixedly connected to the through connecting frame 35 and the two conveying gears 32, so that the second motor 31 can drive the conveying gears 32 to rotate.

[0056] Place the crucible 6 onto the double-speed chain 33 and turn on the second motor 31. The output of the second motor 31 will drive the gearbox 39, thereby causing the output of the gearbox 39 to drive the two conveying gears 32 to rotate synchronously. This further causes the upper half of the double-speed chain 33 to move towards the inside of the frame 1. When the double-speed chain 33 moves inside the aluminum profile 34, the wheel of the double-speed chain 33 will press against the bottom surface of the sliding groove inside the aluminum profile 34 under the pressure of the crucible 6. As the chain of the double-speed chain 33 moves towards the inside of the frame 1, the bottom of the wheel of the double-speed chain 33 is affected by the reaction force, thus rotating clockwise. The top of the wheel of the double-speed chain 33 will drive the crucible 6 to move further towards the inside of the frame 1, so that the crucible 6 is quickly conveyed into the inside of the frame 1.

[0057] Reference Figures 6-7The lifting frame mechanism 4 is used to lift the sagger 6 that has been conveyed into the frame 1. The lifting frame mechanism 4 includes a lifting fixing frame 41 disposed inside the bottom frame 12. The width of the lifting fixing frame 41 is less than the length of the connecting rod 38. The lifting fixing frame 41 can be movably inserted between the two aluminum profiles 34. The top of the lifting fixing frame 41 is equally divided with several roller groups 46. Each roller group 46 has at least four rollers 461 inside. The top of the rollers 461 abuts against the bottom of the sagger 6. The bottom of the lifting fixing frame 41 is fixedly connected to the top of the support plate 42. The support plate 42 has an installation hole 45 in the middle of its bottom surface. The bottom of the lifting fixing frame 41 is fixedly connected to the top of the support plate 43. The support plate 43 has a limit groove 44 in the bottom. The top of the inner side of the limit groove 44 abuts against the top of the movable end gear 522 of the rack and pinion jack 52.

[0058] The rack and pinion synchronous lifting mechanism 5 can drive the lifting frame mechanism 4, which can simultaneously lift multiple saggars 6 transported to the inside of the frame 1 by the double speed chain 33. When lifting, the roller group 46 on the top of the lifting fixing frame 41 will abut against the bottom of the saggar 6. The rolling of the roller group 461 reduces the friction between the roller and the saggar 6, making it easier for the push-pull mechanism 2 to push the saggar 6 out of the inside of the frame 1.

[0059] Reference Figures 7-8 The rack and pinion synchronous lifting mechanism 5 is used to control the up and down movement of the lifting frame mechanism 4. The rack and pinion synchronous lifting mechanism 5 includes a support frame 53 fixedly connected to the bottom inner side of the bottom frame 12. The top center of the support frame 53 is fixedly connected to the bottom surface of the mounting plate 54. The mounting end of the lifting cylinder 51 is fixedly connected to the top surface of the mounting plate 54. The output end of the lifting cylinder 51 is fixedly connected to the bottom of the floating joint 55. The mounting end of the floating joint 55 passes through the mounting hole 45 and is fixedly connected to the support plate 42. Four rack and pinion lifters 52 are fixedly installed at the four corners of the top of the support frame 53. Each rack and pinion lifter 52 includes a base with a fixed end. The rack and pinion 521 and the movable end of the rack and pinion jack 52 have their base 521 extending through the top of the support frame 53 to the bottom of the support frame 53. The four rack and pinion jacks 52 are connected in series by four connecting shafts 56 to form a whole, thereby realizing the function of synchronous lifting. The mounting end of the third motor 57 is fixedly connected to the top of the support frame 53 near the gearbox 2 58. The surface of the connecting shaft 56 near the third motor 57 is fitted with the gearbox 2 58. The output end of the third motor 57 is fixedly connected to the input end of the gearbox 2 58. The bottom of the gearbox 2 58 is fixedly connected to the top of the support frame 53.

[0060] When the lifting cylinder 51 is activated, its output end drives the floating joint 55 to move. When the floating joint 55 moves, it drives the support plate 42 to move, thereby driving the lifting frame mechanism 4 to move. This ensures that the roller group 46 at the top of the lifting frame 41 and the roller group 14 at the top of the bottom frame 12 are at the same height, making it easier for the subsequent push-pull mechanism 2 to push the sagger 6 to the kiln entrance simultaneously. At the same time, the third motor 57 is activated. Its output end drives the gearbox 58, which in turn drives the connecting shaft 56 to rotate. Through the transmission of the connecting shaft 56, the gears 522 of the four rack lifters 52 are raised and lowered synchronously, further allowing the top of the gear 522 to abut against the bottom of the support plate 43, providing support for the lifting frame mechanism 4 and enhancing stability.

[0061] Among them, the wiring connections of the first motor 22, the second motor 31 and the third motor 57 to each motor are all existing technologies, and their structural principles will not be described in detail here. The rack and pinion jack 52 is an existing product, and its internal structural principles will not be described in detail here.

[0062] The implementation principle of a furnace-transferring machine according to an embodiment of this application is as follows: The saggers 6 are sequentially placed onto the double-speed chain 33. The second motor 31 is turned on, causing the double-speed chain 33 to drive the saggers 6. Guided by roller 13, several saggers 6 are transported into the machine frame 1. The lifting cylinder 51 and the third motor 57 are turned on, causing the roller 461 at the top of the lifting fixing frame 41 to simultaneously lift several saggers 6, making the surface of roller 461 flush with the surface of roller 241. Then, the first motor 22 is turned on, causing the synchronous belt pulley assembly 21 to drive the push-pull frame 24 and the push-pull plate 23 to move on the slide rail 25. The push-pull plate 23 will simultaneously push multiple saggers 6, causing the saggers 6 to move to the kiln inlet with the assistance of roller 461 and roller 241.

[0063] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
