During the operation of the equipment, the flipping gear is subjected to a large force during the meshing process with the chain link. Sometimes, due to different operating speeds or guide deviations, the flipping gear and the chain link cannot be fully meshed, which causes greater wear on the chain link and affects the stable operation of the equipment. Therefore, a flipping mechanism is proposed. Utility Model Content

The flexible block can be any one of a circular ring structure, a U-shaped structure, and a fan-shaped structure, which improves the various applicability of the flexible block.
[0008] Preferably, the slot is in an arc shape or a dovetail groove shape. The shape of the slot is not limited to the slot in the above-mentioned figure. The slot may also be in a dovetail groove shape or other structures.

[0015] It can be seen from the above technical solutions that the embodiments of the utility model have the following advantages:
[0016] The utility model discloses a flipping mechanism. When the chain link and the flipping gear are misaligned in meshing, the flipping gear is squeezed by the force of the pallet. The flexible block between the flipping unit mounting seat and the flipping gear can produce a certain amount of elastic compression.

[0029] See also Figure 1-Figure 3 One embodiment of the utility model provides an embodiment of a flip mechanism, including a flip unit 2 installed on a transmission shaft 6, the flip unit 2 including a flip gear 21, a flip unit mounting seat 23 and a flexible block 24, the flip unit mounting seat 23 is fixedly mounted on the outer wall of the transmission shaft 6, the flip gear 21 is arranged on the outer wall of the flip unit mounting seat 23, and a gap is arranged between the flip gear 21 and the flip unit mounting seat 23, and the flexible block 24 is arranged in the middle of the gap between the flip gear 21 and the flip unit mounting seat 23.
[0030] In an optional embodiment, the flip gear 21 is composed of two half-toothed rings, and the butting end faces of the two half-toothed rings are provided with a clamping groove 22, and the two half-toothed rings are clamped together through the clamping groove 22 to form the flip gear 21.
[0031] In an optional embodiment, the flexible block 24 is any one of a circular ring structure, a U-shaped structure, and a fan-shaped structure. Therefore, the flexible block 24 can adopt any one of a circular ring structure, a U-shaped structure, and a fan-shaped structure, thereby improving the various applicability of the flexible block 24.
[0032] In an optional embodiment: the flip unit 2 is fixedly mounted on the side wall of the transmission shaft 6 .
[0033] It should be noted that the structure of the flip gear 21 is that the interior of the flip gear 21 is hollow and divided into two halves, which are locked by meshing with each other through a circular groove; the flip unit mounting seat 23 is installed on the transmission shaft 6, and a flexible block 24 is installed between the flip gear 21 and the flip unit mounting seat 23, and the torque of the flip gear 21 is transmitted to the flip gear 21 through the flexible block 24; the form of the flip unit mounting seat 23, wherein, Figure 2 The flexible block 24 in the semicircular contact part, Figure 3The four convex blocks in contact with the flexible block 24 are evenly distributed around the circumference. Figure 3 The contact part with the flexible block 24 is in the shape of a dovetail groove evenly distributed along the circumference; in the form of a flexible block, the flexible block 24 is distributed on the rotating shaft along the circumference, and the flexible block 24 is installed between the circumference of the flip unit mounting seat 23 and the flip gear 21. The inner circumference direction of the flexible block 24 contacts the flip unit mounting seat 23, and the outer circumference direction contacts the flip gear 21; the flip gear 21 and the flip unit mounting seat 23 have no contact, and are connected and contacted through the flexible block 24.
[0034] Furthermore, the flip unit 2 has 3 different versions, Figure 2 The support block 25 in the flip unit 2 is placed in the flexible block 24, in order to prevent the flip gear 21 from squeezing the flexible block 24 and causing excessive deformation when the flip force is too large. When the chain link 1 is misaligned with the flip gear 21, the flip gear 21 is squeezed by the force of the tray 7, and the flexible block 24 located between the flip unit mounting seat 23 and the flip gear 21 can produce a certain amount of elastic compression. When the flip gear 21 and the chain link 1 are stuck at the dead point to a certain extent, the elastic compression causes the flip gear to change position with the compression force, so that the flip gear jumps the tooth after turning the stuck point, which will not cause the tray 7 to stop at the flip position, and at the same time avoid the wear of the flip gear 21 and the chain link 1 caused by the stuck teeth. The flip gear 21 transmits torque through the flip unit mounting seat 23 installed on the transmission shaft 6. When the torque is overloaded, it can be compressed and deformed to make the flip gear 21 eccentric, thereby changing the position of the flip gear 21.
[0035] Among them, it should be noted that Figure 2 and Figure 3 Figure 4 The difference is Figure 2 The support blocks 25 are evenly installed in the circular structure of the flexible block 24, so that the force on the flip gear 21 is relatively uniform and can cope with more complex working conditions. Figure 3 and Figure 4 Able to operate in simple working conditions where the load is not that large;
[0036] Figure 3 and Figure 2 The difference is that the meshing form between the flip gear 21 and the flip unit mounting seat 23 is different. Figure 3 and Figure 2 Fewer parts than Figure 2 The support block 25, Figure 3 Compared to Figure 2 The structure is simpler and Figure 2 The larger area of the middle flexible block 24 has a greater elastic variation. Figure 4 and Figure 3 The structures are similar but the difference is that they have the same function. Figure 4 The smaller the area of the flexible block 24, the lower the cost.
[0037] In an optional embodiment, the slot 22 is in an arc shape or a dovetail groove shape.
[0038] It should be noted that the shape of the slot 22 on the flip gear 21 in the present invention is not limited to the slot 22 in the above-mentioned figure, and the slot 22 may also be in a dovetail groove shape or other structures.
[0039] In an optional embodiment, the flexible block 24 and the supporting block 25 are distributed on the rotating shaft in a circular shape.
[0040] It should be noted that, by adopting the flexible blocks 24 and the support blocks 25 distributed in a circular shape, the distribution of the flexible blocks 24 and the support blocks 25 is ensured to be more reasonable.
[0041] In an optional embodiment, it also includes a chain link 1, a locking member 5, a tray 7 and a guide profile 8, wherein the locking member 5 is fixedly mounted on the transmission shaft 6. The tray 7 is matched and mounted on the outer side of the flip unit 2, wherein the locking member 5 is preferably a locking nut.
[0042] In an optional embodiment: a chain link 1 is slidably connected in the groove in the guide profile 8 , and the top of the chain link 1 is fixedly connected to the bottom of the tray 7 .
[0043] It should be noted that when the chain link 1 and the flip gear 21 are misaligned, the flip gear 21 is squeezed by the force of the tray 7, and the flexible block 24 between the flip unit mounting seat 23 and the flip gear 21 can produce a certain amount of elastic compression. When the flip gear 21 and the chain link 1 are stuck at the dead point to a certain extent, the elastic compression causes the flip gear to change position with the compression force, so that it turns past the stuck point and jumps teeth, which will not cause the tray 7 to be stuck in the flip position, and at the same time avoid the wear of the flip gear 21 and the chain link 1 caused by the stuck teeth. The flip gear 21 transmits torque through the flip unit mounting seat 23 installed on the transmission shaft 6. When the torque is overloaded, it can be compressed and deformed to make the flip gear 21 eccentric, thereby changing the position of the flip gear 21.
[0044] In an optional embodiment: the guide profile 8 is fixedly mounted on the frame of the conveyor by means of bolts.
[0045] It should be noted that the installation position of the guide profile 8 on the conveyor is clearly defined so that the guide profile 8 can receive the chain link 1 during use.
[0046] Working principle: When in use, when the chain link 1 and the flip gear 21 are misaligned, the flip gear 21 is squeezed by the force of the tray 7, and the flexible block 24 between the flip unit mounting seat 23 and the flip gear 21 can produce a certain amount of elastic compression. When the flip gear 21 and the chain link 1 are stuck at the dead point to a certain extent, the elastic compression causes the flip gear to change position with the compression force, so that it turns past the stuck point and jumps teeth, which will not cause the tray 7 to be stuck in the flip position, and at the same time avoid the wear of the flip gear 21 and the chain link 1 caused by the stuck teeth. The flip gear 21 transmits torque through the flip unit mounting seat 23 installed on the transmission shaft 6. When the torque is overloaded, it can be compressed and deformed to make the flip gear 21 eccentric, thereby changing the position of the flip gear 21.
