[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-6 A dual-channel automatic material receiving device for a two-roll rolling mill comprises a two-roll rolling mill 1 for rolling alloy sintered billets into alloy sheets and a receiving trough 3 for receiving alloy sheets 2. A belt conveyor mechanism 4 and a receiving platform 5 are sequentially arranged in front of the discharge side of the two-roll rolling mill 1. A first roller conveyor mechanism 6 and a second roller conveyor mechanism 7 with opposite conveying directions are arranged in parallel on one side of the two-roll rolling mill 1 and the receiving platform 5, which are respectively used to convey the receiving trough 3 between the feed side of the two-roll rolling mill 1 and the receiving platform; and a first pushing mechanism 8 and a second pushing mechanism 9 are respectively used to push the receiving trough 3 between the receiving platform 5 and the first roller conveyor mechanism 6 and the second roller conveyor mechanism 7.

[0024] In the utility model, the first roller conveyor mechanism 6 and the second roller conveyor mechanism 7 share a frame 10, and the position of the first roller conveyor mechanism 6 on the frame 10 is close to the two-roller rolling mill 1 and the material receiving table 5, so as to realize the material receiving trough 3 being conveyed to one side of the feeding side of the two-roller rolling mill 1; the position of the second roller conveyor mechanism 7 on the frame 10 is far away from the two-roller rolling mill 1 and the material receiving table 5, so as to realize the material receiving trough 3 being conveyed to one side of the material receiving table 5.

[0025] In the utility model, the material receiving table 5 includes two side frames 51 and a table top 52 fixedly connected to the top of the two side frames 51, a crossbeam 53 is fixedly connected between the upper parts of the two side frames 51, a guide groove 11 extending inward from the outer edge is provided on the table top 52, and two guide rails 12 are fixedly connected to the bottom surface of the table top 52.

[0026] In the utility model, the first pushing mechanism 8 includes a first cylinder 81 and a pushing portion 82. The two ends of the cylinder barrel of the first cylinder 81 are fixedly mounted on the frame 10 and the cross beam 53 respectively. The piston rod of the first cylinder 81 passes through the cross beam 53 and extends to the outside of the table 52. The end of the piston rod of the first cylinder 81 is fixedly connected with a connecting plate 83. The two sides of the connecting plate 83 are fixedly connected with two cross bars 84 extending inward to the bottom of the table 52 respectively; the pushing portion 82 includes a base 821 and a pushing block 822 integrally connected to the base 821. The base 821 is fixedly mounted on the two cross bars 84 on the one hand, and is slidably mounted on the two guide rails 12 on the other hand. The pushing block 822 can move along the guide groove 11.

[0027] Thus, by retracting the piston rod of the first cylinder 81, the connecting plate 83 is driven to move inward, driving the two cross bars 84 to move inward, and then driving the base 821 to move inward along the two guide rails 12, so that the push block 822 moves inward along the guide groove 11, thereby pushing the material receiving trough 3 from the material receiving table 5 to the feed end of the first roller conveyor mechanism 6.

[0028] In the present invention, the front side and the outer edge of the table 52 are respectively fixedly connected with baffles 13 to play a limiting role and prevent the receiving trough 3 from sliding off the table 52 during the pushing process.

[0029] In the utility model, a vertical plate 14 is fixedly connected to the outer side of the frame 10 , and two guide sleeves 15 are fixedly connected to the two sides of the vertical plate 14 .

[0030] In the present invention, the second pushing mechanism 9 includes a second cylinder 91 and a push plate 92 . The cylinder body of the second cylinder 91 is fixed to the outer side of the vertical plate 14 . The piston rod of the second cylinder 91 penetrates the vertical plate 14 from outside to inside and is fixedly connected to the push plate 92 .

[0031] Thus, by extending the piston rod of the second cylinder 91, the push plate 92 is driven to move inward, so that the push plate 92 sequentially crosses the second roller conveyor mechanism 7 and the first roller conveyor mechanism 6, and moves to the top of the table 52, so as to push the material receiving trough 3 from the discharge end of the second roller conveyor mechanism 7 to the material receiving table 5.

[0032] In the present invention, two guide rods 93 extending outward are respectively fixedly connected to both sides of the push plate 92 , and the two guide rods 93 are respectively slidably sleeved in the two guide sleeves 15 .

[0033] The utility model is further described below in conjunction with the accompanying drawings:

[0034] In the initial state, the piston rod of the first cylinder 81 is in an extended state, at which time the push block 822 is located at the outer end of the guide groove 11 and does not contact the receiving groove 3 on the table 52. At the same time, the piston rod of the second cylinder 91 is in a retracted state, at which time the outer side of the second roller conveyor mechanism 7 does not contact the receiving groove 3 moved to the discharge end of the second roller conveyor mechanism 7.

[0035] During the rolling operation, an operator feeds the alloy sintered billet to be rolled into the feed side of the two-roll rolling mill 1. After the alloy sheet 2 is initially rolled by the two-roll rolling mill 1, it is discharged from the discharge side of the two-roll rolling mill 1, and then transported by the belt conveyor mechanism 4 to fall into the receiving trough 3 waiting on the receiving platform 5.

[0036] Next, the piston rod of the first cylinder 81 retracts, driving the connecting plate 83 to move inward, driving the two cross bars 84 to move inward, and then driving the base 821 to move inward along the two guide rails 12, so that the push block 822 moves inward along the guide groove 11, pushing the receiving trough 3 carrying the alloy sheet 2 from the receiving table 5 to the feed end of the first roller conveyor mechanism 6.

[0037] The receiving trough 3 is conveyed to the feed side of the two-roller rolling mill 1 through the conveyance of the first roller conveyor mechanism 6. At this time, the operator can remove the receiving trough 3 from the discharge end of the first roller conveyor mechanism 6, take out the alloy sheet 2, and then place the empty receiving trough 3 at the feed end of the second roller conveyor mechanism 7.

[0038] Then, the operator feeds the alloy sheet 2 into the feed side of the two-roll rolling mill 1 for secondary rolling.

[0039] The empty material receiving trough 3 is conveyed to one side of the material receiving platform 5 by the second roller conveyor mechanism 7. At this time, the piston rod of the second cylinder 91 extends to drive the push plate 92 to move inward, so that the push plate 92 sequentially crosses the second roller conveyor mechanism 7 and the first roller conveyor mechanism 6, and moves to the top of the table surface 52, pushing the material receiving trough 3 from the discharge end of the second roller conveyor mechanism 7 to the material receiving platform 5, and waiting again after the material receiving trough 3 is in place.

[0040] Similarly, the alloy sheet 2 after secondary rolling is discharged from the discharge side of the two-roll rolling mill 1, and then transported by the belt conveyor mechanism 4, and falls into the receiving trough 3 waiting on the receiving platform 5.

[0041] The above process is repeated repeatedly until multiple rolling processes are completed, and finally an alloy sheet that meets the process requirements is obtained.

[0042] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0043] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
