A guide roller is mounted on the side end of the roller mounting seat, and the guide roller rolls along the guide rail. A pressure plate is locked and mounted above the arc-shaped push plate. The arc-shaped push plate is controlled to move forward by the pushing member. When the displacement reaches the point where the pressure plate does not restrict the arc-shaped push plate, the return spring assists the arc-shaped push plate to stand up. A limit opening for limiting the backward flipping of the arc-shaped push plate is provided on the roller mounting seat. The arc push plate is installed on the roller mounting seat through a pin shaft, and based on the pin shaft as the rotation axis, the arc push plate can rotate on one side of the roller mounting seat based on the pin shaft as the rotation base point; the guide roller is installed on the roller mounting seat through an axle rod, and the guide roller is used to assist the roller mounting seat in shifting.

[0018] like Figure 1-Figure 10 As shown, a roller conveyor with an ejection device comprises a power assembly 1, a conveying roller 2, a pushing member, an ejection device 4, a guide roller 5, a pressure plate 6, and a guide rail 7. The power assembly 1 is drivingly connected to the conveying roller 2. The ejection device 4 comprises a roller mounting seat 41, an arc-shaped push plate 42, a return spring 43, and a pin 44. The arc-shaped push plate 42 is rotatably mounted on the roller mounting seat 41 through the pin 44, and a return spring 43 for cooperating in lifting and lowering the arc-shaped push plate 42 is nested and mounted on the pin 44. A guide roller 5 is mounted on the side end of the roller mounting seat 41. The guide roller 5 rolls along the guide rail 7. A pressure plate 6 is locked and mounted above the arc-shaped push plate 42. The arc-shaped push plate 42 is controlled by the pushing member to move forward. When the displacement reaches the point where the pressure plate 6 does not restrict the arc-shaped push plate 42, the return spring 43 assists the arc-shaped push plate 42 to stand up. A limit opening 411 for limiting the backward flipping of the arc-shaped push plate 42 is provided on the roller mounting seat 41. The arc push plate 42 is installed on the roller mounting seat 41 through the pin shaft 44. Based on the pin shaft 44 as the rotation axis, the arc push plate 42 can rotate on one side of the roller mounting seat 41 based on the pin shaft 44 as the rotation base point; the guide roller 5 is installed on the roller mounting seat 41 through the shaft rod, and the guide roller 5 is used to assist the displacement of the roller mounting seat 41.

[0019] Furthermore, the power assembly 1 includes a motor, a transmission shaft, a sprocket, and a chain. A sprocket is installed at the output end of the motor, and the sprocket drives the conveying roller 2 to rotate through the transmission shaft and the chain.

[0020] Furthermore, the pushing member is a pushing cylinder 3 .

[0021] Furthermore, it also includes a support leg 8 and a roller mounting frame 9, on which a plurality of conveying rollers 2 are mounted, and the support leg 8 is mounted at the bottom end of the roller mounting frame 9.

[0022] Furthermore, at least two ejection devices 4 are arranged on the roller conveyor.

[0023] Furthermore, a supporting plane 10 is provided on the roller conveyor.

[0024] Furthermore, the arc-shaped push plate 42 bounces up under the action of the return spring 43, and the front end of the arc-shaped push plate 42 contacts the pallet at its front end, pushing the entire pallet completely to the lower section of the unpowered roller line.

[0025] Furthermore, after the arc-shaped push plate 42 bounces up, the angle between its bottom end and the roller conveyor is ninety degrees.

[0026] Furthermore, at least two guide rollers 5 are installed on both sides of the roller mounting seat 41 .

[0027] Furthermore, the conveying roller 2 forms a plurality of conveying surfaces on the roller conveyor 200 .

[0028] When the roller conveyor 200 with the ejection device in the present invention is used in conjunction with the unpowered roller line, the material 300 enters from one side of the roller conveyor 200 and is transported forward by the conveying roller 2 until the material 300 advances to the unpowered roller line 100 on the lower loading mechanism. At this time, the material 300 will lack power and slip at the joint, and cannot be transported in one piece. The movable end of the pushing cylinder 3 is connected to the roller mounting seat 41, and the pushing cylinder 3 is started. The roller mounting seat 41 and the arc push plate 42 on the roller mounting seat 41 are synchronously controlled to move, and the pushing device 4 is pushed out along the guide rail 7; when the arc push plate 42 is not below the pressure plate 6, the elastic force of the return spring 43 is not limited by the pressure plate 6, and the arc push plate 42 is lifted under the influence of the return spring 43. Usually, the angle between the bottom end of the arc push plate 42 and the overall top surface of the roller conveyor 200 is ninety degrees. The arc push plate 42 contacts the side of the material 300, and with the cooperation of the pushing cylinder 3, the material 300 is pushed from one side of the roller conveyor 200 to the unpowered roller line; if the bottom end of the material 300 is carried by a pallet, similarly, when the pushing cylinder 3 is retracted, the arc push plate 42 is pressed to below the conveying surface through the pressure plate 6. During the pallet transportation, the pushing device 4 does not wear the bottom of the pallet and does not affect the service life of the pallet.

[0029] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
