Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0028] In this embodiment, the automatic falling mechanism includes a stamping mechanism and a clamping mechanism. The stamping mechanism includes a stamping cylinder 2, a stamping plate 3, a stamping block 4 and a pressure base 5. The clamping mechanism includes a falling plate 6, a connecting rod 7, a spring 8 and a clamping block 9. When in use, the stamping cylinder 2 is driven to drive the stamping plate 3 to be squeezed toward the pressure plate. At this time, the material plate is located on the pressure plate. Under the action of the stamping cylinder 2, the material plate is stamped into a standard accessory. At this time, the accessory is very easy to adhere to the stamping block 4. When the stamping cylinder 2 returns, the block 9 passes through the notch 26 on the stamping plate 3 and contacts the falling plate 6. At this time, the falling plate 6 is separated from the stamping plate 3 by force, and the spring 8 begins to be stretched, and the connecting rod 7 slides in the pressure plate. At this time, if the spring 8 breaks under force, the connecting rod 7 will limit the falling plate 6, and the length of the connecting rod 7 in the cooperation is exactly the length between the static position of the falling plate 6 after contacting the block 9 and the end position of the stamping plate 3 after the stamping cylinder 2 returns.

[0029] In this embodiment, the material conveying mechanism includes a displacement motor 14, a first lead screw 15, a movable frame 16, a clamping plate 17, a clamping motor 18 and a second lead screw 19. When in use, when the material plate processed as an accessory enters the inside of the main body 1 inside the roller 10, after the first round of stamping, the remaining material plate begins to be transported to the outside of the main body 1. At this time, the displacement motor 14 drives, the first lead screw 15 rotates, and the movable frame 16 installed on the first lead screw 15 is mobilized to slide inside the first slide groove 21 on the conveying box 20, and the clamping motor 18 slides inside the second slide groove 22. At this time, the clamping motor 18 drives the second lead screw 19, so that the two clamping plates 17 move towards each other. When the contact pad 27 contacts the material plate, the clamping motor 18 stops driving. At this time, the displacement motor 14 reverses, the movable frame 16 returns to its original position, and the clamping motor 18 reverses to release the material plate, thereby reciprocating.

[0030] In this embodiment, the positioning mechanism includes a roller 10, a positioning rod 11, a butterfly nut 12 and a positioning rail 13, and the positioning rail 13 is provided with a storage plate 24 and a roller 25. When in use, when the material plate processed as an accessory enters the main body 1 inside the roller 10, and the material plate is transported by the material conveying mechanism, the position of the material plate may be offset, etc. At this time, the positioning rod 11 is slid inside the third slide groove 23 to position the material plate laterally. At this time, the butterfly nut 12 is tightened to limit the movement of the positioning rod 11, and the material plate is also placed inside the positioning rail 13. At this time, the bottom end of the material plate contacts the storage plate 24, thereby positioning the longitudinal position of the material plate, and the cross section of the material plate contacts and slides with the roller 25. Example

[0031] To sum up, when in use, the stamping cylinder 2 is driven to drive the stamping plate 3 to be squeezed toward the pressure plate. At this time, the material plate is located on the pressure plate. Under the action of the stamping cylinder 2, the material plate is stamped into a standard accessory. At this time, the accessory is very easy to adhere to the stamping block 4. When the stamping cylinder 2 returns, the block 9 passes through the notch 26 on the stamping plate 3 and contacts the falling plate 6. At this time, the falling plate 6 is separated from the stamping plate 3 by force, and the spring 8 begins to be stretched, and the connecting rod 7 slides in the pressure plate. At this time, if the spring 8 is broken by force, the connecting rod 7 will limit the falling plate 6. And in the cooperation, the length of the connecting rod 7 is just the length between the static position after the falling plate 6 contacts the block 9 and the end position of the stamping plate 3 after the return stroke of the stamping cylinder 2 is completed, so as to prevent the stamping cylinder 2 from pulling the stamping plate 3 and the connecting rod 7 and spring 8 on the falling plate 6 due to the too low position of the block 9. When the material plate processed as the accessory enters the main body 1 inside the roller 10, after the first round of stamping, the remaining material plate begins to be transported to the outside of the main body 1. At this time, the displacement motor 14 is driven, the first screw 15 rotates, and the first screw 15 installed on the first screw 1 is mobilized. 5 slides inside the first slide groove 21 on the conveying box 20, and the clamping motor 18 slides inside the second slide groove 22, and at this time, the clamping motor 18 drives the second lead screw 19 to make the two clamping plates 17 move towards each other. When the contact pad 27 contacts the material plate, the clamping motor 18 stops driving, and the displacement motor 14 reverses at this time, the movable frame 16 returns to the original position, and the clamping motor 18 reverses to release the material plate, thereby reciprocating. When the material plate processed into the accessory enters the main body 1 inside the roller 10, and the material plate passes through the material conveyor After the material plate is transported by the mechanism, the position of the material plate may be offset. At this time, the positioning rod 11 is slid inside the third slide groove 23 to position the material plate laterally. At this time, the butterfly nut 12 is tightened to limit the movement of the positioning rod 11. The material plate is also placed inside the positioning rail 13. At this time, the bottom end of the material plate contacts the placement plate 24, thereby positioning the longitudinal position of the material plate, and the cross section of the material plate contacts and slides with the roller 25. The longitudinal position positioning is to prevent the material plate from falling due to the influence of gravity, thereby contacting the clamping plate 17 prematurely and affecting the operation of the material transportation mechanism.

[0032] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
