DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings.

[0030] The embodiment of the present application discloses an egg tray pushing and flipping device.

[0032] The bracket 11 is placed on the ground, and the chain conveying mechanism 12 is installed on the bracket 11. The chain conveying mechanism 12 includes a chain 121 and a power mechanism for driving the chain 121 to rotate. There are two chains 121, and the power mechanism includes a driving shaft (not shown in the figure), a driving sprocket (not shown in the figure), a driven shaft 122, a driven sprocket 123 and a power assembly. The driving shaft and the driven shaft 122 are both rotatably connected to the bracket 11, and the driving shaft and the driven shaft 122 are arranged in parallel. There are two driving sprockets, and the driving sprocket is fixed to the driving shaft with a key connection, and the driving sprocket is arranged on the edges of the driving shaft near both ends; there are also two driven sprockets 123, and the two driven sprockets 123 are fixed to the driven shaft 122 with a key connection, and the driven sprocket 123 is arranged on the edges of the driven shaft 122 near both ends. The chain 121 is wound around the driving sprocket and the driven sprocket 123, and the two chains 121 are distributed in parallel.

[0033] Reference Figure 1 and Figure 2 , both ends of the tray 13 are rotatably connected to the two chains 121, and the tray 13 is located between the two chains. Specifically, both ends of the tray 13 are connected with a rotating rod 131, one end of the rotating rod 131 is rotatably connected to the chain 121, and the other end is fixedly connected to the tray 13; or one end of the rotating rod 131 is fixedly connected to the chain 121, and the other end is rotatably connected to the tray 13; or both ends of the rotating rod 131 are rotatably connected to the chain 121 and the tray 13, respectively.

[0034] The bottoms of both ends of the mounting frame 14 are fixed to the upper end of the bracket 11 , and the mounting frame 14 is located above the chain 121 and the tray 13 .

[0035] The cylinder body of the push cylinder 15 is fixedly mounted on the mounting frame 14 , the piston rod of the push cylinder 15 is arranged in the horizontal direction, and the extension and retraction direction of the piston rod of the push cylinder 15 is opposite to the conveying direction of the chain 121 .

[0036] Reference Figure 1 and Figure 2 The two ends of the push bracket 16 are slidably connected to the bracket 11, and the push bracket 16 is fixedly connected to the piston rod of the push cylinder 15. The bottom of the push bracket 16 is located just above the tray 13 on the upper part of the chain 121, and the gap between the push bracket 16 and the tray 13 is small. When in use, the push bracket 16 can push the pulp egg tray on the tray 13.

[0037] Specifically, a slide bar 21 is provided at the upper end of the bracket 11, and the bottoms of both ends of the push bracket 16 are slidably connected to the slide bar 21, and the axis of the slide bar 21 is parallel to the axis of the piston rod of the push cylinder 15. A push plate 22 is provided at the bottom of the push bracket 16, and the push plate 22 is located between the tray 13 and the push bracket 16, and the push plate 22 is used to push the pulp egg tray on the tray 13.

[0038] Reference Figure 1 and Figure 2 In order to adjust the height of the push-support plate 22 on the push-support bracket 16, a screw 23 is rotatably connected to the upper end of the push-support plate 22, and the screw 23 is arranged in the vertical direction. A vertical through hole is opened on the push-support bracket 16, and the screw 23 passes through the through hole and extends from the top of the push-support bracket 16. A nut 24 is threadedly connected to the screw 23, and the nut 24 is located above the push-support bracket 16. When in use, the height of the push-support plate 22 on the push-support bracket 16 is adjusted by screwing the nut 24 on the screw 23, thereby adjusting the gap between the push-support plate 22 and the tray 13. The number of screws 23 can be one or more. If the number of screws 23 is more than one, the more than one screws 23 are evenly distributed on the push-support plate 22.

[0039] In order to reduce the weight of the push and support plate 22 , a plurality of weight-reducing holes are provided at intervals on the push and support plate 22 .

[0040] Reference Figure 1 and Figure 2 Both ends of the flip shaft 17 are rotatably connected to the bracket 11 , the flip shaft 17 is arranged parallel to the driven shaft 122 , and the flip shaft 17 is located on a side of the driven shaft 122 away from the driving shaft.

[0041] The bottom of the flip plate 18 is fixedly mounted on the flip shaft 17 , and the height of the flip plate 18 is slightly lower than the height of the tray 13 on the upper chain 121 , so that the push plate 22 can push the pulp egg tray on the tray 13 onto the flip plate 18 .

[0042] Reference Figure 1 and Figure 2 One end of the connecting rod 19 is sleeved on the flip shaft 17, the connecting rod 19 is fixedly connected to the flip shaft 17, and the other end of the connecting rod 19 is a free end.

[0043] The cylinder body of the flip cylinder 20 is hinged on the bracket 11, and the piston rod of the flip cylinder 20 is hinged to the free end of the connecting rod 19. When in use, the piston rod of the flip cylinder 20 is extended and retracted and drives the flip shaft 17 to rotate through the connecting rod 19.

[0044] Reference Figure 1 and Figure 2 In order to enable the turning plate 18 to better turn over the pulp egg tray on its upper end, a plurality of partition plates 25 are evenly mounted and fixed on the upper end of the turning plate 18 .

[0045] The conveyor belt (not shown in the figure) is located on the side of the turning plate 18 away from the chain conveying mechanism 12. The turning plate 18 turns the pulp egg tray onto the conveyor belt by continuously turning.

[0046] Further, refer to Figure 1 and Figure 2 The driven shaft 122 is also provided with four sensors 31, which are evenly distributed along the circumferential direction of the driven shaft 122. The bracket 11 is provided with a sensor switch 32, which is located directly below the sensor 31 rotating on the driven shaft 122. When in use, the sensor 31 can touch the sensor switch 32, so that the sensor switch 32 is activated, and then the push cylinder 15 and the flip cylinder 20 are controlled to operate, so as to move the pulp egg tray from the tray 13 to the conveyor belt.

[0047] Specifically, the power mechanism drives the chain 121 to rotate, and the chain 121 drives the tray 13 to rotate. When the tray 13 on the chain 121 is transmitted from the bottom to the top, the piston rod of the push cylinder 15 extends out and drives the push bracket 16 to move. The push plate 22 on the push bracket 16 pushes the pulp egg tray on the tray 13 onto the flip plate 18, and then the piston rod of the flip cylinder 20 extends out and drives the flip shaft 17 to rotate through the connecting rod 19. The flip shaft 17 drives the flip plate 18 to flip, and the flip plate 18 flips the pulp egg tray at its upper end onto the conveyor belt, thereby completing the process of moving the pulp egg tray from the tray 13 to the conveyor belt, replacing the process of manually moving the pulp egg tray from the tray 13 to the conveyor belt, which greatly reduces the labor intensity of the staff.
