DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] refer to Figure 1-Figure 7 , a preheating mechanism for a casting platform for aluminum alloy casting rod production, comprising:

[0027] The main body 100 has a feed inlet 101 and a discharge outlet 102 at the top and bottom of the main body 100 respectively;

[0028] A frame 103 connected to the casting platform, the frame 103 is connected to the bottom of the main body 100;

[0029] A hopper 104 is disposed on the top of the main body 100, and a feeding port 105 is provided at the bottom of the hopper 104;

[0030] A plurality of heaters 106 are distributed around the main body 100, and the heating ends of the heaters 106 extend into the main body 100;

[0031] At least two stirring rods 107 are rotatably connected to the top of the main body 100, and the outer side walls of the stirring rods 107 are connected to a plurality of blades 108;

[0032] The baffle 109 is rotatably disposed in the material drop opening 105. A rotating hole 110 communicating with the material drop opening 105 is provided on one side of the hopper 104. A rotating rod 111 connected to the baffle 109 is rotatably sleeved in the rotating hole 110.

[0033] Among them, a driving structure for rotating the stirring rod 107 is provided on one side of the main body 100;

[0034] A quantitative material discharging structure for rotating a rotating rod 111 is provided between the hopper 104 and the main body 100. The rotating rod 111 can rotate along with the rotation of the stirring rod 107. The quantitative material discharging structure can rotate the baffle 109 half a circle when the stirring rod 107 rotates one circle. The rotating rod 111 can be reset after the rotation.

[0035] By setting up the hopper 104, the staff can put aluminum ingots and other raw materials for casting aluminum alloy casting rods into the hopper 104. The position of the material in the hopper 104 is limited by the baffle 109. The staff starts the driving structure and the heater 106. The driving structure can drive the stirring rod 107 to rotate. The rotation of the stirring rod 107 can rotate the position of the rotating rod 111 through the quantitative discharge structure. The rotation of the rotating rod 111 can drive the baffle 109 to rotate. After the baffle 109 rotates, the raw materials in the hopper 104 can fall into the main body 100 through the drop port 105 and the feed port 101. For example, raw materials such as aluminum ingots can be melted by the action of the heater 106. At the same time, the stirring rod 107 rotates to use the external blades 108 to stir the solution in the main body 100, so that the molten aluminum alloy casting rod raw materials can be fully mixed. When the rod 107 rotates one circle, it can drive the rotating rod 111 and the baffle 109 to rotate half a circle. The raw materials in the hopper 104 are not blocked by the baffle 109 and fall into the main body 100. The stirring rod 107 stirs the solution and intermittently feeds materials into the main body 100. After the quantitative feeding structure rotates the rotating rod 111, the rotating rod 111 can be reset to block the material in the hopper 104 again. During the period of no material falling, the heater 106 can be given time to melt the aluminum ingots and other materials in the main body 100, thereby achieving the effect of timed and quantitative feeding of materials. Compared with the preheating mechanism in the prior art, the device can feed the raw materials into the main body 100 in a timed and quantitative manner through the quantitative feeding structure, thereby solving the problem of the prior art that the solution temperature drops sharply due to excessive feeding at one time.

[0036] As a further solution of the present invention, the quantitative discharging structure includes a worm 206 rotatably connected to the top of the main body 100, a support block 208 is fixedly connected to the top of the main body 100, a rotating rod 209 is rotatably sleeved on the support block 208, one end of the rotating rod 209 is fixedly connected to a worm wheel 210 meshing with the worm 206, the other end of the rotating rod 209 is fixedly connected to an incomplete gear 211, one end of the rotating rod 111 is fixedly connected to a gear 212 adapted to the incomplete gear 211, the diameter of the incomplete gear 211 is larger than the diameter of the gear 212, a rotating groove 213 is opened on the inner side wall of the rotating hole 110, a volute spring 214 is connected between the rotating rod 111 and the rotating groove 213, and the driving structure can drive the worm 206 to rotate when the stirring rod 107 is rotated;

[0037] By setting the worm 206, when the staff starts the driving structure to drive the stirring rod 107 to rotate, the worm 206 can be driven to rotate. The rotation of the worm 206 can drive the incomplete gear 211 to rotate through the rotating rod 209. When the incomplete gear 211 rotates, it meshes with the gear 212 to drive the gear 212 to rotate. The rotation of the gear 212 can drive the baffle 109 to rotate through the rotating rod 111. When the rotating rod 111 rotates, the volute spring 214 generates potential energy, thereby achieving the effect of rotating the baffle 109. When the full gear 211 rotates one circle, it can drive the baffle 109 to rotate half a circle. The raw materials in the hopper 104 can enter the main body 100 through the drop port 105 and the feed port 101. When the incomplete gear 211 is disengaged from the gear 212, the volute spring 214 releases the potential energy to drive the rotating rod 111 to reset. The rotating rod 111 resets and the baffle 109 follows its reset. The baffle 109 can block the drop port 105 again, thereby achieving the effect of blocking the drop port 105 after dropping the material to block the raw materials in the hopper 104.

[0038] As a further solution of the present invention, the driving structure includes a support plate 200 fixedly connected to one side of the main body 100, a driving motor 201 is connected to the support plate 200, a first chain 202 is connected between the driving shaft of the driving motor 201 and one of the stirring rods 107, two rotating tubes 203 are rotatably connected to the top of the main body 100, a second chain 204 is connected between the two rotating tubes 203, a third chain 205 is connected between the stirring rod 107 and an adjacent rotating tube 203, and a fourth chain 207 is connected between one of the stirring rods 107 and the worm 206;

[0039] By setting the driving motor 201, the staff starts the driving motor 201, and the driving shaft of the driving motor 201 rotates, which can drive one of the stirring rods 107 to rotate. The stirring rod 107 rotates through the second chain 204 and the rotating tube 203 to drive the other stirring rod 107 to rotate, thereby achieving the effect of rotating the stirring rod 107 to stir the solution in the main body 100. When the stirring rod 107 rotates, the worm 206 can be driven to rotate through the fourth chain 207, thereby achieving the effect of rotating the worm 206, and the worm 206 rotates through the worm wheel 210, the rotating rod 209, the incomplete gear 211, the gear 212 and the rotating rod 111. Further, the rotating tube 203 is set, which can bypass the position of the feed port 101 when the driving motor 201 uses the second chain 204 and the third chain 205 to drive the two stirring rods 107, thereby avoiding the problem of raw materials colliding with the transmission structure.

[0040] As a further solution of the present invention, vibration plates 300 are respectively provided on both sides of the interior of the hopper 104, and a plurality of connection grooves 301 are provided on the inner bottom surface of the hopper 104. The bottom of the connection groove 301 is fixedly connected with a limit rod 302 slidably sleeved with the vibration plate 300, and a vibration member for moving the vibration plate 300 up and down is provided on the vibration plate 300;

[0041] By setting a vibration piece, the vibration piece can move the position of the vibration plate 300 up and down, and can shake the aluminum ingots and other raw materials in the hopper 104. The shaking of the aluminum ingots in the hopper 104 can prevent the aluminum ingots from piling up around the hopper 104 and failing to reach the position of the discharge port 102, thereby achieving a uniform discharge effect.

[0042] As a further solution of the present invention, the vibrating member includes a plurality of connecting grooves 301 provided on the inner bottom surface of the hopper 104, a limiting rod 302 slidably sleeved with the vibrating plate 300 is fixedly connected to the bottom of the connecting groove 301, a spring 303 is connected between the vibrating plate 300 and the connecting groove 301, a rotating groove 304 is provided on the inner side wall of the rotating hole 110, and a cam 305 rotatably sleeved with the rotating groove 304 is fixedly sleeved on the outer side wall of the rotating rod 111;

[0043] By setting the cam 305, when the rotating rod 111 rotates, the rotating rod 111 can drive the cam 305 to rotate. The rotation of the cam 305 can collide with the position of the vibration plate 300, and the vibration plate 300 moves upward. The spring 303 generates potential energy. When the cam 305 rotates and disengages from the vibration plate 300, the spring 303 releases the potential energy and drives the vibration plate 300 to reset. The cam 305 can be used to generate potential energy until the spring is stretched, and the potential energy is released to drive the vibration plate 300 to reset. The vibration plate 300 can be moved up and down to shake the raw materials in the hopper 104.

[0044] As a further solution of the present invention, a shroud 112 is connected between the main body 100 and the hopper 104, and the shroud 112 is connected to the drop port 105 and the feed port 101;

[0045] By providing the enclosure 112 , the position of the raw materials can be blocked, thereby preventing the problem of materials such as aluminum ingots colliding with the feed port 101 and being ejected to the outside when falling from the hopper 104 to the feed port 101 .

[0046] As a further solution of the present invention, a plurality of brackets 113 are connected to the inner top surface of the main body 100, and the brackets 113 are rotatably connected to the stirring rod 107;

[0047] By providing the bracket 113 , the stability of the stirring rod 107 during rotation can be increased.

[0048] As a further solution of the present invention, a side groove 400 is provided on one side of the inner part of the discharge port 102, a bottom opening 402 communicating with the side groove 400 is provided on the bottom of the main body 100, a material blocking plate 401 is slidably sleeved in the side groove 400, a cylinder 403 is connected to one side of the inner part of the bottom opening 402, and a telescopic shaft of the cylinder 403 is connected to the material blocking plate 401;

[0049] By setting the cylinder 403, when it is necessary to release the solution in the main body 100 to cast the aluminum alloy cast rod, the cylinder 403 is started, and the telescopic shaft of the cylinder 403 drives the baffle plate 401 to leave the discharge port 102. At this time, the solution in the main body 100 can fall out from the discharge port 102.

[0050] As a further solution of the present invention, a scraper block 404 is fixedly connected to one side of the inner portion of the discharge port 102;

[0051] By providing the scraper 404 , when the baffle plate 401 is away from the discharge port 102 , the scraper 404 can scrape off the solution on the baffle plate 401 , thereby preventing the solution on the baffle plate 401 from adhering to the side trough 400 due to natural cooling after entering the side trough 400 .

[0052] Working principle: by setting up the hopper 104, the staff can put aluminum ingots and other raw materials for casting aluminum alloy casting rods into the hopper 104. The position of the material in the hopper 104 is limited by the baffle 109. The staff starts the driving structure and the heater 106. The driving structure can drive the stirring rod 107 to rotate. The rotation of the stirring rod 107 can rotate the position of the rotating rod 111 through the quantitative discharge structure. The rotation of the rotating rod 111 can drive the baffle 109 to rotate. After the baffle 109 rotates, the raw materials in the hopper 104 can fall into the main body 100 through the drop port 105 and the feed port 101. For example, raw materials such as aluminum ingots can be melted by the action of the heater 106. At the same time, the stirring rod 107 rotates to use the external blades 108 to stir the solution in the main body 100, so that the molten aluminum alloy casting rod raw materials can be fully mixed. When the stirring rod 107 rotates one circle, it can drive the rotating rod 111 and the baffle 109 to rotate half a circle. The raw materials in the hopper 104 are not blocked by the baffle 109 and fall into the main body 100. The stirring rod 107 stirs the solution while intermittently feeding materials into the main body 100. After the quantitative feeding structure rotates the rotating rod 111, the rotating rod 111 can be reset to block the material in the hopper 104 again. During the period of no material falling, the heater 106 can be given time to melt the aluminum ingots and other materials in the main body 100, thereby achieving the effect of timed and quantitative feeding of materials. Compared with the preheating mechanism in the prior art, the device can feed the raw materials into the main body 100 in a timed and quantitative manner through the quantitative feeding structure, thereby solving the problem of the prior art that the solution temperature drops sharply due to excessive feeding at one time.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
