[0029] In this embodiment, by setting up the adjustment mechanism 2, the press body 1 can be adaptively adjusted according to the size of the object to be stamped, so that the object can fall into the receiving container according to the established conveying route. In addition, a fixed shaft 26 and a roller 27 are provided, and the roller 27 can rotate around the fixed shaft 26, so that when the object moves on the feed plate 21, it will not be trapped on the feed plate 21 due to friction.

[0030] Example 2
[0031] like Figure 1 , Figure 5 and Figure 6As shown, a flip mechanism 3 is provided on one side of the adjustment mechanism 2, and the flip mechanism 3 includes a fixed plate 31, which is fixedly connected to the press body 1, a rotating rod 32 is fixedly connected to one side of the fixed plate 31, a rotating disk 33 is sleeved on the outer surface of the rotating rod 32, the rotating disk 33 is rotatably connected to the rotating rod 32, a supporting rod 34 is fixedly connected to the outer surface of the rotating disk 33, a side of the supporting rod 34 is provided with a side block 35, the side block 35 is fixedly connected to the feeding plate 21, a sliding column 36 is passed through the interior of the supporting rod 34 and the side block 35, the sliding column 36 is slidably connected to the side block 35, the sliding column 36 is fixedly connected to the support rod 34, a bolt 37 is passed through the interior of the fixed plate 31 and the rotating disk 33, the bolt 37 is slidably connected to the fixed plate 31 and the rotating disk 33, a nut 38 is sleeved on the outer surface of the bolt 37, and the nut 38 is threadedly connected to the bolt 37.
[0032] In this embodiment, by setting up the flip mechanism 3, the inclination angle of the feed plate 21 can be adjusted, so that it can be suitable for the feeding and transportation of more types of processing objects. When the turntable 33 rotates, the support rod 34 can drive the slide column 36 to slide in the slide groove provided on the side block 35, so as to achieve the purpose of adjusting the use angle of the feed plate 21. In addition, the fixed plate 31 and the turntable 33 are provided with mounting holes that match the bolts 37, so that the bolts 37 and the nuts 38 can tightly fix the turntable 33 and the fixed plate 31 after rotation adjustment.
[0033] Working principle:
[0034] like Figure 1-Figure 6As shown, when the utility model is in use, if the weight of the workpiece is large, the use angle of the feed plate 21 can be adjusted to a gentle state. At this time, the support rod 34 is used to drive the turntable 33 to rotate around the turntable 32, and the support rod 34 rotates counterclockwise. At the same time, the feed plate 21 will rotate around the rotation axis 29 until the inclination angle of the feed plate 21 is relatively gentle, and when the support rod 34 rotates, it will drive the sliding column 36 to slide in the side block 35, and then the bolt 37 is passed through the fixed plate 31 and the turntable 33 at the same time, and the nut 38 is threadedly connected to the bolt 37 to ensure the stability of the feed plate 21 when in use. Then, the distance between the two guide plates 25 is adjusted according to the size of the object, and the two-way rotation is driven by the handle 202. The threaded rod 23 rotates, and the bidirectional threaded rod 23 will threadably drive the two threaded blocks 24, so that the two threaded blocks 24 move in the same direction and in the opposite direction on the bidirectional threaded rod 23 at the same time, until the distance between the two guide plates 25 is slightly larger than the size of the object. At this time, the press body 1 is started, and the object to be stamped will fall on the top of the feed plate 21 by itself. Since the feed plate 21 is inclined, the object will slide into the receiving container under the action of the roller 27, and the impact force of contact with other objects is small. If the weight of the object is small and it is in the form of a thin sheet, the flip mechanism 3 can be used to adjust the use angle of the feed plate 21 to a steeper state to ensure that the object will not be trapped on the top of the feed plate 21.
