Description

Technical Field

[0001] The present invention relates to the resource recycling industry, and particularly to an automatic waste recycling system for die-casting machines. Background Art

[0002] A die-casting machine is a special equipment that quickly presses molten metal into the cavity of a metal mold under high pressure and cools and solidifies in the cavity to obtain castings with certain shapes and properties, and is widely used in the field of metal part forming.

[0003] Currently, radiator units are also die-cast by die-casting machines to replace the welding process, which not only improves efficiency but also avoids problems that are prone to occur in welding, such as missed welding and false welding. During the die-casting process of the die-casting machine, affected by air pressure, temperature, and mold wear, unqualified parts - waste will appear. Since aluminum has the characteristic of being recyclable, these wastes can be recycled and remelted for reuse to reduce material waste; for example, the patent with the application number CN202322301804.2 discloses an aluminum round sheet stamping waste recycling and melting furnace, which conveys the waste through an aluminum round sheet stamping waste conveying component, and its aluminum round sheet stamping waste conveying component uses a spiral blade to convey the waste to the melting furnace.

[0004] The above patent has two problems: 1. The capacity of the melting furnace is limited and the addition needs to be carried out according to a plan, and it cannot be added when there is material. Therefore, the waste generated by the die-casting machine either needs to be transferred and stored or directly added to the feeding device. Transferring and storing will add two additional moving processes, which will greatly increase the workload, and directly adding to the feeding device will cause accumulation and even damage the feeding device; 2. The shape of the radiator during die-casting cannot be conveyed by a spiral blade and can only be conveyed by an ordinary conveyor. The ordinary conveyor cannot stop for a long time and does not have the ability to stack waste. Therefore, an additional structure is needed to store and adjust the feeding rhythm. Summary of the Invention

[0005] Based on the deficiency in the prior art that it is impossible to temporarily store and adjust the feeding rhythm according to settings, thus unable to ensure the continuous progress of material conveying, the addition of waste according to the plan, and the efficient progress of the entire waste recycling process, the present invention provides an automatic waste recycling system for die-casting machines.

Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary, and should not be construed as limiting the protection scope of the present invention.

[0037] It should be noted that like reference numerals represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0038] This embodiment mainly elaborates on the title of the automatic waste recycling system beside the die-casting machine, specifically as follows:

[0039] The automatic waste recycling system beside the die-casting machine, as Figure 1-6 shown, includes a feeding device 10, an automatic feeding device 20, and a melting furnace 30. The feeding device 10, the automatic feeding device 20, and the melting furnace 30 are connected in sequence to send the waste to the melting furnace 30 for heating and reuse. The automatic feeding device 20 includes:

[0040] A Y-axis track 202, which is arranged on the ground, and the tail end of the feeding device 10 is arranged in the middle of the Y-axis track 202;

[0041] A translation table, which is slidably arranged on the Y-axis track 202 and is driven by a driving device to slide on the Y-axis track 202;

[0042] A feeding device, which includes two sets symmetrically arranged front and back. When the two sets of feeding devices move along the Y-axis track 202, they are alternately docked with the tail end of the feeding device 10. The feeding device includes:

[0043] A feeding rack 204, which is arranged on the translation table;

[0044] A lifting rack 206, which is slidably arranged on the feeding rack 204 along the Z-axis;

[0045] A driving cylinder 205, which is arranged on the feeding rack 204 and its output end is connected to the lifting rack 206;

[0046] A receiving rack 208, which is slidably arranged on one side of the lifting rack 206, and is provided with receiving grooves thereon. It includes a plurality of them and is arranged in a staggered manner. The upper receiving rack 208 is close to the melting furnace 30 side and the lower receiving rack 208 is close to the feeding device 10 side;

[0047] The material pushing mechanism 207 includes a material pushing plate 2072 disposed in the material receiving groove, a material pushing piston cylinder 2071 disposed on the side wall of the material receiving frame 208, and a material pushing rod 2073 disposed at the output end of the material pushing piston cylinder 2071. The material pushing rod 2073 extends into the material receiving groove and is connected to the material pushing plate 2072. A strip-shaped hole 2081 is provided on the material receiving frame. The material pushing rod 2073 passes through the strip-shaped hole 2081 and is connected to the material pushing plate 2072, and the material pushing rod 2073 moves along the strip-shaped hole 2081.

[0048] The first piston cylinder 210 is provided corresponding to the material receiving frame 208 one by one. It includes a first cylinder body having a first piston chamber. A first piston rod 2101 is disposed in the first piston chamber, and the first piston rod 2101 is connected to the material receiving frame 208.

[0049] The second piston cylinder 209 is provided in one-to-one correspondence with the material receiving rack 208. It includes a second cylinder body having a second piston chamber and a third piston chamber. A second piston rod 2091 is provided in the second piston chamber. The second piston rod 2091 is connected to the lifting frame 206. A third piston rod 2094 is provided in the third piston chamber. Two spaced annular limiting platforms 2093 are provided on the third piston rod 2094, and a transmission sleeve 2092 is slidably sleeved on the third piston rod 2094. The transmission sleeve 2092 is connected to the lifting frame 206 and slides between the two annular limiting platforms 2093 driven by the lifting frame 206. When the transmission sleeve 2092 continues to move upward after abutting against the top annular limiting platform 2093, it drives the third piston rod 2094 to move upward. When the transmission sleeve 2092 continues to move downward after abutting against the bottom annular limiting platform 2093, it drives the third piston rod 2094 to move downward. The spacing gradients of the annular limiting platforms 2093 on different piston rods are set such that the material receiving racks 208 at different heights perform pushing actions when rising to different heights. The second piston chamber is communicated with the first piston chamber through an air pipe, and the third piston chamber is communicated with the inner chamber of the pushing piston cylinder 2071 through an air pipe. In this solution, two groups are provided, and each group includes multiple layers of material receiving racks 208. During material receiving, the material is received layer by layer step by step, and then added to the melting furnace 30 according to the plan. This not only realizes temporary storage but also realizes according to the plan. In addition, it combines a cylinder and multiple piston cylinders to drive the cylinder to operate simultaneously when the lifting frame 206 rises, so as to ensure that the material receiving rack 208 moves synchronously while rising, making the movement trajectory of the material receiving rack 208 an arc, ensuring that it moves from below the feeding device 10 to above the melting furnace 30 without interference, and at the same time pushing the waste material into the melting furnace 30 when reaching the predetermined position. The specific process is as follows: When the lifting frame 206 rises and falls, the second piston rod 2091 follows and rises, and the gas inside is pressed towards the first piston chamber to drive the first piston rod 2101 to move and drive the material receiving rack 208 to move. In this way, the material receiving rack 208 has speeds in both directions. By setting different inner diameters of the two piston cylinders and giving an acceleration to the rising speed, the curved movement of the material receiving rack 208 can be realized to avoid interference; after the above process has been carried out for a period of time, when the transmission sleeve 2092 abuts against the upper annular limiting platform 2093 on the third piston rod 2094 and then moves upward, it pushes up the third piston rod 2094 to squeeze the gas in the third piston chamber into the pushing piston cylinder 2071, driving the pushing rod 2073 of the pushing piston cylinder 2071 to move, and finally driving the pushing plate 2072 to move in the material receiving groove to push the waste material into the melting furnace 30. When running in the reverse direction, when the transmission sleeve 2092 abuts against the lower annular limiting platform 2093 on the third piston rod 2094 and then moves downward, it is reset. Since the pushing times of the material receiving racks 208 at different heights are different, an idle stroke is set through the annular limiting platform 2093 and the transmission sleeve 2092 to lag the pushing time.

[0050] Preferably, the distance between adjacent material receiving racks 208 is a, and the distance difference between the annular limiting platforms 2093 of the third piston rods 2094 for driving the pusher plates 2072 on two adjacent material receiving racks 208 is also a.

[0051] Preferably, the material receiving racks 208 have the same starting position for discharging. During the process that the material receiving racks 208 move to the smelting furnace 30 from the starting position for discharging until the discharging is completed, the moving stroke of the second piston rod 2091 is b, and when the stroke of the second piston rod 2091 is b, the moving stroke of the pusher rod 2073 is equal to the length c of the material receiving rack 208; b < c, and the diameter of the second piston chamber is greater than the inner diameter of the pusher piston cylinder 2071. By setting the diameters of the piston chambers differently in this solution, the strokes of the two piston rods are ensured to be different to match their respective required strokes.

The center of the arc-shaped plate is located on the rotation center line of the turning cylinder 103. The arc-shaped plate is in small clearance fit with the tail end of the feeder 101 so that the waste at the tail end of the feeder 101 is conveyed to the middle plate body and is poured onto the material receiving rack 208 during turning. A limiting rod is arranged on the frame to support and limit the side of the middle plate body closer to the arc-shaped plate when the middle plate body is turned to the horizontal position. During feeding, the middle plate body is horizontal, and the waste automatically falls onto the middle plate body. During discharging, the middle plate body turns, and the arc-shaped plate blocks the end of the feeder 101 to temporarily block the waste on the feeder 101. After the discharging is completed, it quickly turns back to the original position for the next feeding.
