Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy production technology, and in particular to a feeding device for aluminum alloy production. Background Technology

[0002] In addition to the general properties of aluminum, aluminum alloys also have some specific alloy properties due to the different types and amounts of alloying elements added. In the process of producing aluminum alloys, it is often necessary to input and add raw materials to existing aluminum alloy production equipment such as melting furnaces at the front end of the production line.

[0003] Chinese patent document CN220304226U discloses a feeding device for aluminum alloy production, including a raw material barrel, a feeding frame, and a controller. The raw material barrel has several support rods evenly distributed at its bottom, and a discharge port is located on one side of its bottom. A door is hinged to the top of one end of the feeding frame, and a support plate is hinged to the bottom of the other end. The distance between the feeding frame and the melting furnace is less than the distance between the support plate and the melting furnace. Control mechanisms are symmetrically arranged at both ends of the door and the feeding frame. A lifting mechanism is provided between the bottom of the feeding frame and one end of the support plate. The device also includes a vertical adjustment mechanism and a horizontal adjustment mechanism. This invention solves the problem that in traditional aluminum alloy production, the feeding of raw materials is usually done manually by workers, which is not only physically demanding but also harmful to workers' health due to prolonged and frequent contact with raw materials.

[0004] The existing technology has the following problems:

[0005] The feeding device uses a screw to drive the hopper to move. Since the hopper needs to move for a long time, the screw wears out significantly. At the same time, the screw drive makes it difficult for the hopper to move quickly. Also, the vertical screw cannot be too high, otherwise it will be difficult to support the hopper.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-6 As shown, a feeding device for aluminum alloy production includes a base 1, a mechanism platform 2 movably installed on the right side of the base 1, a conveyor belt 3 movably installed on the inner side of the mechanism platform 2, a hopper 4 overlapping the upper inclined surface of the base 1, a fixed shaft 5 fixedly connected to the middle of the front and rear sides and the upper right side of the hopper 4, and a connecting mechanism 6 movably sleeved on the outer side of the two fixed shafts 5 on the same side, and two connecting mechanisms 6 are symmetrically distributed in the front and rear, and a rotating mechanism 7 is fixedly connected to the upper side of the base 1 near the right side.

[0028] The rotating mechanism 7 includes a motor 71. The lower side of the motor 71 is fixedly connected to the upper part of the base 1, slightly to the right. The output end of the motor 71 is fixedly connected to a transmission rod 72. The front and rear ends of the transmission rod 72 are fixedly connected to two first winding discs 73 distributed in the front and rear. The front and rear sides of the mechanism platform 2 are rotatably connected to two first fixed pulleys 75 distributed in the front and rear. The inner sides of the two first winding discs 73 are wound with a first traction rope 74. The end of the first traction rope 74 away from the first winding disc 73 is fixedly connected to the side of the left fixed shaft 5 that is away from each other.

[0029] It should be noted that the base 1 and the mechanism platform 2 are fixedly connected together by the first pin. The inner side of the first traction rope 74 overlaps the right side of the first fixed pulley 75. The motor 71 drives the transmission rod 72 to rotate. When the transmission rod 72 rotates, the first winding disc 73 rotates. When the first winding disc 73 rotates, the first traction rope 74 is tightened or extended on the first winding disc 73. When the first traction rope 74 is tightened on the first winding disc 73, it pulls the hopper 4 to rotate, so that the material in the hopper 4 is tilted onto the conveyor belt 3. The hopper 4 contains a weighing mechanism for weighing the material in the hopper 4. The conveyor belt 3 is provided with multiple partitions. The material is tilted between two adjacent partitions. The conveyor belt 3 is used to transport the material, so that the material is tilted into the furnace.

[0030] like Figure 5 As shown, the connecting mechanism 6 includes a connecting arm 61. The inner side of the connecting arm 61 is movably sleeved on the outer side of the fixed shaft 5. Two mechanism rings 62 distributed on the left and right are fixedly connected to the inner side of the groove on the side of the connecting arm 61 away from the hopper 4. The inner side of the mechanism rings 62 is movably sleeved on the outer side of the fixed shaft 5. Several annularly distributed balls 63 are movably sleeved on the inner side of the sidewalls of the two mechanism rings 62. The outer side of the balls 63 is movably sleeved in the ball groove opened on the outer side of the fixed shaft 5. The outer side of the two mechanism rings 62 is rotatably connected to a limit ring 64. Several annularly distributed disengagement grooves 66 are opened on the inner side of the two limit rings 64.

[0031] It should be noted that a torsion spring is provided between the limiting ring 64 and the mechanism ring 62. In the initial state, the disengagement groove 66 and the ball 63 are misaligned, so that the limiting ring 64 fixes the ball 63, preventing the connecting arm 61 from moving on the fixed shaft 5. Rotating the limiting ring 64 aligns the disengagement groove 66 with the ball 63, allowing the ball 63 to move, which in turn allows the connecting arm 61 to move. The two fixed shafts 5 work together to prevent the connecting arm 61 from rotating around the fixed shaft 5, while strengthening the connection between the connecting arm 61 and the fixed shaft 5.

[0032] like Figure 5 As shown, each of the two limiting rings 64 has an insertion hole 65 on the side away from the hopper 4 and near the top.

[0033] It should be noted that the insertion hole 65 extends to the inner side of the connecting arm 61 on the side of the hopper 4. In the initial state, the insertion hole 65 on the limiting ring 64 and the insertion hole 65 on the connecting arm 61 are misaligned. A cylindrical tool is inserted into the insertion hole 65 on the limiting ring 64 to make the limiting ring 64 rotate. When the insertion hole 65 on the limiting ring 64 and the insertion hole 65 on the connecting arm 61 are aligned, inserting the cylindrical tool into the insertion hole 65 on the connecting arm 61 can limit the limiting ring 64 and prevent the limiting ring 64 from resetting.

[0034] like Figure 3 As shown, a fixed arm 67 is fixedly connected to the lower middle part of the connecting arm 61.

[0035] It should be noted that the upper inclined platform of the base 1 is provided with round shafts on the front and rear sides. When the connecting arm 61 moves to the position of fitting the hopper 4, the round shafts are inserted into the inner side of the fixed arm 67, so that the connecting arm 61 fixes the hopper 4 and the base 1.

[0036] like Figure 4As shown, a fixed sleeve 68 is movably sleeved on the inner side of the connecting arm 61 near the right end. A bearing 69 is fixedly sleeved on the inner side of the fixed sleeve 68. A rotating shaft 610 is fixedly sleeved on the inner side of the bearing 69. The outer side of the rotating shaft 610 is movably sleeved on the front and rear sides of the mechanism platform 2 near the left side, near the hopper 4.

[0037] It should be noted that the fixed sleeve 68 and the connecting arm 61 are fixedly connected together by the second pin. After the rotating shaft 610 is installed in place, the rotating shaft 610 is fixed in place, so that the connecting arm 61 can rotate around the rotating shaft 610.

[0038] like Figure 6 As shown, two second winding discs 76 are fixedly connected to the outer side of the transmission rod 72 near the front and rear sides. Two second fixed pulleys 77 are rotatably connected to the inner side of the left wall of the upper inclined platform of the base 1. A second traction rope 78 is wound around the inner side of each of the two second winding discs 76. The end of the second traction rope 78 away from the second winding disc 76 is fixedly connected to the lower side of the hopper 4.

[0039] It should be noted that when the transmission rod 72 rotates, it drives the second winding disc 76 to rotate. When the first traction rope 74 extends from the inside of the first winding disc 73, the second traction rope 78 extends from the inside of the second winding disc 76 to pull the hopper 4 back to its original position.

[0040] like Figure 6 As shown, the second traction rope 78 is made of elastic material.

[0041] It should be noted that the material used for the second traction rope 78 avoids the problem of inconsistent elongation between the second traction rope 78 and the first traction rope 74.

[0042] The working principle of this utility model is as follows: First, the inner side of the first traction rope 74 is attached to the right side of the first fixed pulley 75. The motor 71 drives the transmission rod 72 to rotate. When the transmission rod 72 rotates, the first winding disc 73 rotates. When the first winding disc 73 rotates, the first traction rope 74 is either tightened or extended on the first winding disc 73. When the first traction rope 74 is tightened on the first winding disc 73, it pulls the hopper 4 to rotate, causing the material in the hopper 4 to tilt onto the conveyor belt 3. The hopper 4 contains a weighing mechanism for weighing the material in the hopper 4. The conveyor belt 3 is equipped with multiple partitions, and the material is tilted between two adjacent partitions. The conveyor belt 3 is used to transport the material, causing the material to tilt into the furnace. When the transmission rod 72 rotates, it drives the second winding disc 76 to rotate. When the first traction rope 74 extends from the inside of the first winding reel 73, the second traction rope 78 extends from the inside of the second winding reel 76 to pull the hopper 4 back to its original position. The material used for the second traction rope 78 avoids the problem of inconsistent extension and retraction between the second traction rope 78 and the first traction rope 74. The motor 71 drives the transmission rod 72 to rotate, causing the hopper 4 to rotate, so that the material in the hopper 4 is tilted onto the conveyor belt 3. Relying on the partition, the hopper 4 can quantitatively convey material into the furnace, avoiding the problems of high wear, low strength, and slow conveying caused by using a screw. Finally, the base 1 and the mechanism 2 are fixedly connected together by the first pin. A torsion spring is provided between the limit ring 64 and the mechanism ring 62. In the initial state, it is disengaged. The groove 66 and the ball 63 are misaligned, allowing the retaining ring 64 to fix the ball 63, preventing the connecting arm 61 from moving on the fixed shaft 5. Rotating the retaining ring 64 aligns the disengagement groove 66 with the ball 63, allowing the ball 63 to move, which in turn allows the connecting arm 61 to move. The two fixed shafts 5 work together to prevent the connecting arm 61 from rotating around the fixed shafts 5, while strengthening the connection between the connecting arm 61 and the fixed shafts 5. The insertion hole 65 extends towards the hopper 4 to the inner side of the connecting arm 61. Initially, the insertion hole 65 on the retaining ring 64 and the insertion hole 65 on the connecting arm 61 are misaligned. A cylindrical tool is inserted into the insertion hole 65 on the retaining ring 64, causing it to rotate. When the retaining ring 64 rotates, the connecting arm 61 moves. When the insertion hole 65 on the retaining ring 64 and the insertion hole 65 on the connecting arm 61 are aligned, a cylindrical tool is inserted into the insertion hole 65 on the connecting arm 61 to limit the retaining ring 64 and prevent it from resetting. The upper inclined platform of the base 1 has round shafts on both the front and rear sides. When the connecting arm 61 moves to the position where it fits against the hopper 4, the round shafts are inserted into the inner side of the fixed arm 67, causing the connecting arm 61 to fix the hopper 4 and the base 1. The fixed sleeve 68 is fixedly connected to the connecting arm 61 by a second pin. After the rotating shaft 610 is installed in place, the rotating shaft 610 is fixed in place, allowing the connecting arm 61 to rotate around the rotating shaft 610. The pin allows the fixed sleeve 68 to be quickly fixed onto the connecting arm 61, relying on the rotation of the retaining ring 64.This design allows the connecting arm 61 to slide or be fixed on the fixed shaft 5, enabling the hopper 4 to be quickly connected to the mechanism platform 2 via the connecting arm 61. This facilitates installation and disassembly, allowing the base platform 1 and mechanism platform 2 to be easily separated for storage when not in use. It also allows the mechanism platform 2 and conveyor belt 3 to be removed and used independently, enhancing their versatility.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
