The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0029] See also Figure 1-7A reversing mechanism comprises a fixed member 10, an input wheel 20, a first end transmission structure 50, a second end transmission structure 60, a transmission wheel 70, a driven wheel 80, a moving member 90, a cam 92, a lever 93 and a mounting wheel 95, wherein the input wheel 20 is fixedly connected to the driven wheel 80, the transmission wheel 70 and the driven wheel 80 are rotatably mounted on the moving member 90, the first end transmission structure 50 is meshed with the transmission wheel 70 for transmission, and the second end transmission structure 60 is meshed with the driven wheel 80 for transmission; the first end transmission structure 50 and the second end transmission structure 60 are rotatably mounted on both ends of the moving member 90, respectively, the cam 92 and the mounting wheel 95 are rotatably mounted on the fixed member 10, the lever 93 is mounted on the cam 92, and the lever 93 pushes the moving member 90 to move up and down, so that the first end transmission structure 50 or the second end transmission structure 60 is meshed with the mounting wheel 95 for transmission. During operation, the external power drives the input wheel 20 to rotate, so that the transmission wheel 70 and the driven wheel 80 rotate, and the lever 93 pushes the moving part 90 to move up and down, so that the first end transmission structure 50 or the second end transmission structure 60 engages with the mounting wheel 95 for transmission, thereby realizing the reversing function. In the actual operation process, the reversing mechanism is installed in conjunction with a roller, so that the drum does not run in one direction during reversal, and finally the drum mouth will turn to the bottom of the drum so that the internal metal parts fall into a specific hopper, thereby fully automatically unloading the material. When the unloading time is increased, the drum mouth will turn to the bottom of the drum several times until the metal parts are completely unloaded. When this drum is used in an automatic production line, no manual intervention is required at all, and the drum mouth can simply cooperate with the loader. During the production process, the effective and strong liquid exchange performance and current channel of the drum mouth and the unsealed area of ​​the drum make the work efficiency higher than that of traditional drums.

[0030] Preferably, the reversing mechanism further comprises an output wheel 30, the output wheel 30 is fixedly connected to the mounting wheel 95, and the reversing mechanism further comprises a chain 40, the chain 40 is meshed and transmitted to the output wheel 30. The transmission is performed through the chain 40, and the temperature is high.

[0031] Preferably, the chain 40 includes a stopper 41, and the output wheel 30 drives the chain 40 to rotate, so that the stopper 41 abuts against the lever 93, and the lever 93 pushes the moving member 90 to move, so that the first end transmission structure 50 or the second end transmission structure 60 meshes and transmits with the mounting wheel 95. Specifically, there are two stoppers 41, and the chain 40 is annular. The two stoppers 41 divide the chain 40 into two chain segments, namely, a working chain segment and a blind chain segment.

[0032] It should be noted that, when in normal working state, the lever 93 is located in the working chain section, the block 41 abuts against the lever 93 and causes the lever 93 to push the moving member 90 to move, and the lever 93 moves back and forth between the two blocks 41 to realize the forward and reverse rotation of the chain 40.

[0033] Preferably, the block 41 is provided with an inclined surface 411, and the blind chain segment faces the inclined surface 411. When the lever 93 is moved, the lever 93 slides along the inclined surface 411 to the other side of the block 41, and the inclined surface 411 slides to the working chain segment.

[0034] Preferably, the input wheel 20 includes an input shaft 21, and the input shaft 21 is fixedly connected to the driven wheel 80. The first end transmission structure 50 includes a first gear 51 and a second gear 52, and the first gear 51 and the second gear 52 are respectively rotatably mounted on opposite sides of the moving member 90. The second end transmission structure 60 includes a third gear 61 and a fourth gear 62, and the third gear 61 and the fourth gear 62 are respectively rotatably mounted on opposite sides of the moving member 90. The structure is novel, the design is ingenious, the applicability is strong, and it is easy to promote.

[0035] Preferably, the reversing mechanism further includes a mounting shaft 94, and the lever 93 is Y-shaped, and the lever 93 is mounted on the cam 92 through the mounting shaft 94. The lever 93 rotates along the mounting shaft 94, and the lever 93 can be manually moved to rotate along the mounting shaft 94 to disengage the lever 93 from the contact area of ​​the block 41. When unloading, as long as the lever 93 is manually pushed toward the input wheel 20 to disengage the lever 93 from the contact area of ​​the block 41, the chain 40 causes the roller to continue to rotate in one direction. When the opening is turned downward, the machine power is stopped, and the workpiece can be poured out smoothly. Or the workpiece can be gradually poured out from the inside when it is allowed to rotate continuously and tumble continuously.

[0036] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
