[0039] The following combination Figures 1 to 5 The utility model is described in further detail.

[0040] The utility model embodiment discloses an automatic discharging device for an aluminum rod heating furnace. Figure 1 to Figure 2 An automatic discharging device for an aluminum rod heating furnace includes a supporting frame 1, a lifting mechanism 2 installed on the supporting frame 1, a moving mechanism 3 installed on the lifting mechanism 2, and a clamping mechanism 4 installed on the moving mechanism 3.

[0041] Reference Figures 1 to 3 The lifting mechanism 2 includes a lifting bracket 21 and a first driving assembly 22. A connecting hole is provided at one end of the lifting bracket 21 and a pin is installed in the connecting hole to be fixed on the supporting frame 1. The other end of the lifting bracket 21 is supported on the supporting frame 1. A buffer pad 213 is installed on the end surface where the lifting bracket 21 contacts the supporting frame 1. The cross-section of the lifting bracket 21 is a U-shaped structure. Slide grooves 212 are also respectively arranged on the two opposite inner end surfaces of the lifting bracket 21. The slide grooves 212 extend from the end portion of the lifting bracket 21 and the supporting frame 1 that are rotatably connected to the other end portion. A blocking member 214 is also installed inside the slide groove 212 by bolts. The blocking member 214 is a blocking member made of rubber or resin material. A plurality of rotating shafts are also respectively arranged on the two end surfaces at the top of the lifting bracket 21. The plurality of rotating shafts are arranged in two rows. The two rows of rotating shafts extend respectively along the direction of the slide groove 212, and a rotatable limiting wheel 211 is installed on the rotating shaft.

[0042] In this way, one end of the lifting bracket 21 is rotatably connected to the supporting frame 1, and the other end of the lifting bracket 21 is driven by the first driving component 22. When the lifting bracket 21 rises, the first driving component 22 at one end lifts the lifting bracket 21 and rotates around the other end of the lifting bracket 21. There is no need to lift the entire lifting bracket 21, which reduces the work required to overcome gravity when lifting the lifting bracket 21, effectively saving energy; the slide groove 212 can limit the moving direction of the mobile mechanism 3 and reduce the swing of the mobile mechanism 3 during the movement, so that the mobile mechanism 3 can better maintain stability during movement; the blocking block can limit the moving distance of the mobile mechanism 3 and reduce the failure caused by the mobile mechanism 3 exceeding the moving range. The use of flexible materials can reduce the impact force during collision and extend the service life.

[0043] Reference Figures 2 to 4 The first driving assembly 22 includes a cylinder 225, a rotating shaft 221, a first lever arm 222 and a second lever arm 223. The rotating shaft 221 is rotatably mounted on the support frame 1 through a bearing seat. The central axis direction of the rotating shaft 221 is parallel to the axial direction in which the lifting bracket 21 rotates around the support frame 1. The cylinder 225 is fixedly mounted below the rotating shaft 221. The cylinder body of the cylinder 225 is fixedly mounted on the support frame 1, and the mounting angle between the cylinder body of the cylinder 225 and the lifting bracket 21 is 45°. One end of the first lever arm 222 is fixedly mounted on the rotating shaft 221, and the other end of the first lever arm 222 is rotatably connected to the piston rod of the cylinder 225. The mounting angle between the first lever arm 222 and the piston rod of the cylinder 225 is between 80° and 100°.

Two second lever arms 223 are provided, and the length of the second lever arms 223 is less than the length of the first lever arm 222. One end of the two second lever arms 223 is respectively fixedly provided at the two ends of the rotating shaft 221, and the other ends of the two second lever arms 223 are respectively rotatably connected to the lifting bracket 21, and the position where the lifting bracket 21 and the second lever arm 223 are connected is also provided with a displacement compensating member 224.

[0044] In this way, the cylinder 225 is used and the transmission is carried out through the first lever arm 222 and the second lever arm 223. The structure of the force-saving lever can use the cylinder 225 with small power as much as possible to drive, thereby saving the production cost of the discharge device; the setting of the displacement compensation part 224 can provide position compensation at the connection part and control the moving distance when the first lever arm 222 and the second lever arm 223 move.

[0045] Reference Figures 4 to 5 The moving mechanism 3 includes a moving arm 31 and a second driving assembly 32. Two groups of pulleys 312 are respectively installed on the two side surfaces of the moving arm 31. Each group of pulleys 312 includes a plurality of pulleys 312 evenly distributed along the direction of the slide groove 212. The pulleys 312 are installed in the slide groove 212 for movement. A connecting piece 313 is also provided on the moving arm 31. The connecting piece 313 is a buckle that can be fixedly locked on the transmission connecting chain 323. Two horizontal limiting grooves 311 are also provided on the upper end surface of the moving arm 31. The limiting grooves 311 extend along the direction of the slide groove 212. The two rows of limiting wheels 211 set on the lifting bracket 21 can be respectively stuck in the two limiting grooves 311 for sliding.

[0046] When the pulley 312 is used to drive the movable arm 31 to move in the slide groove 212, friction can be minimized as much as possible, which not only saves energy but also reduces wear; the setting of the horizontal limit groove 311 can reduce the horizontal swing of the movable arm 31 during the movement and maintain the stability of the movable arm 31.

[0047] Reference Figures 1 to 4 The second driving assembly 32 includes a driving motor 321, a sprocket 322 and a chain 323. Two sprockets 322 are provided. The two sprockets 322 are rotatably mounted on the lifting bracket 21 through transmission bearings and bearing seats respectively. The two sprockets 322 are respectively mounted on the two ends of the lifting bracket 21. The driving motor 321 is fixedly mounted on the lifting bracket 21, and the output shaft of the driving motor 321 is fixedly connected to the transmission bearing of one of the sprockets 322. The chain 323 is placed on the two sprockets 322 to play a transmission role. After the connecting piece 313 on the moving arm 31 and the chain 323 are fixedly connected, the chain 323 will drive the moving arm 31 to move.

[0048] In this way, the chain 323 and the sprocket 322 are used to control the movable arm 31 to move along the direction of the slide slot 212, which can minimize friction, reduce power loss, and save energy when moving over a long distance.

[0049] Reference Figures 2 to 5The clamping mechanism 4 includes a claw hand 41 and a third driving assembly 42. An installation bin is provided at the end of the mobile arm 31 close to the first driving assembly 22. Two rotating shafts are horizontally provided in the installation bin. The claw hand 41 includes two claw teeth. Both claw teeth are provided with mounting holes. Both claw teeth are rotated by sleeve-arranging the mounting holes on the rotating shaft in the installation bin. A gear is provided at one end of the claw teeth located inside the installation bin. The third driving assembly 42 includes a telescopic cylinder 225, a rocker arm and a transmission shaft. The telescopic cylinder 225 is fixed on the end of the mobile arm 31 away from the first driving assembly 22. The transmission shaft is rotatably installed on the movable arm 31, and the axial direction of the rotating shaft 221 is the same as the moving direction of the movable arm 31. One end of the rocker arm is fixedly connected to the transmission shaft, and the other end is connected to the piston rod of the cylinder 225 through the displacement compensation member 224. A gear is arranged at the end of the transmission shaft away from the cylinder 225. The gear arranged on the transmission shaft cooperates with the gear on the claw teeth. The transmission shaft is driven to rotate by the extension and contraction of the cylinder 225, and the claw teeth are driven to rotate by the gear at the end of the transmission shaft and the gear at the end of the claw teeth. The claw teeth are arranged as an arc structure.

[0050] In this way, the claw teeth are driven by the cylinder 225 and the rocker arm, and are installed on the end of the movable arm 31 away from the claw teeth. The counterweight at the claw tooth end can be lowered when the movable arm 31 is extended, and the counterweight can be increased at the end away from the claw teeth to maintain the stability of the movable arm 31. The arc-shaped profiling structure of the aluminum rod can further increase the firmness of the clamping of the aluminum rod and reduce the probability of the aluminum rod falling off in the clamping mechanism 4.

[0051] The specific working principle of an automatic discharging device for an aluminum rod heating furnace according to an embodiment of the utility model is as follows: when taking materials, the driving motor 321 rotates forward, the driving motor 321 drives the sprocket 322 to rotate, and the chain 323 on the sprocket 322 drives the connecting piece 313 on the movable arm 31 to move, and the movable arm 31 and the connecting piece 313 extend outward along the slide slot 212 on the lifting bracket 21 together, and when the clamping mechanism 4 moves above the aluminum rod, the third driving component 42 drives the claw hand 41 to clamp the aluminum rod, and then the first driving component 22 drives the lifting bracket 21 to rise upward, driving the clamping mechanism 4 to clamp the aluminum rod and rise, and then the driving motor 321 rotates in the opposite direction, controlling the sprocket 322 and the chain 323 to drive the movable arm 31 to move back until the aluminum rod is moved above the transport trolley, the first driving component 22 controls the lifting bracket 21 to fall, and places the aluminum rod above the moving trolley, and the third driving component 42 controls the claw hand 41 to release the aluminum rod, and then starts the next cycle to take the next aluminum rod out of the heating furnace.

[0052] In summary, in this embodiment, the lifting mechanism 2, the moving mechanism 3 and the clamping mechanism 4 cooperate with each other. When the aluminum rod heating furnace is discharged, the moving mechanism 3 drives the clamping mechanism 4 to extend into the heating furnace, the clamping mechanism 4 clamps the aluminum rod, the lifting mechanism 2 drives the moving mechanism 3, the clamping mechanism 4 and the aluminum rod to rise, the moving mechanism 3 drives the clamping mechanism 4 and the aluminum rod to retract, and the lifting mechanism 2 drives the moving mechanism 3, the clamping mechanism 4 and the aluminum rod to fall. The aluminum rods in the heating furnace are discharged one by one, which reduces the failure rate caused by collision and interference between the aluminum rods during the discharge process, and effectively improves Work efficiency: multiple pulleys 312 are arranged on both sides of the movable arm 31, which cooperate with the slide groove 212 on the lifting bracket 21; and the movable arm 31 is also provided with a horizontal limit groove 311, which cooperates with the limit wheel 211 on the lifting bracket 21, and limits the movable arm 31 in both vertical and horizontal directions, effectively reducing the swing during the movement and significantly improving the operation stability; the claw hand 41 is designed to imitate the circular arc surface of the aluminum rod, so that the claw hand 41 can be more firmly when clamping the aluminum rod, and the probability of the aluminum rod falling off from the claw hand 41 is significantly reduced.
