Referring to fig. 1 and 2, a preferred embodiment of the present invention provides a material cutting device 100, wherein the material cutting device 100 is used for cutting an uncaria hook 200. In this embodiment, the uncaria 200 includes a straight bar 201 and a plurality of hooks 203 equidistantly disposed on the straight bar 201. When the trimming device 100 trims the uncaria hook 200, the straight line 201 and the hook 203 of the uncaria hook 200 are cut and the straight line 201 is segmented. The blanking device 100 comprises a frame 10, a feeding assembly 20 and a blanking mechanism 30. The feeding assembly 20 and the blanking mechanism 30 are both mounted on the frame 10. The feeding assembly 20 is disposed adjacent to the blanking mechanism 30. The feeding assembly 20 is used for feeding the uncaria 200 into the blanking mechanism 30. The material cutting mechanism 30 is used for cutting the uncaria 200 to cut the straight strips 201 and the hook portions 203 on the uncaria 200 and segmenting the straight strips 201.

Referring to fig. 3, the feeding assembly 20 includes a hopper 21 and a feeding roller 23. The hopper 21 is fixedly mounted on the frame 10. The feed roller 23 is rotatably mounted on the frame 10 and the feed roller 23 is partially received in the hopper 21. The gap between the feed roller 23 and the feed hopper 21 forms a feed channel 211. The feeding roller 23 can feed the uncaria 200 into the cutting mechanism 30 from the feeding channel 211 in the rolling process.

The material cutting mechanism 30 includes a driving assembly 31, a material cutting assembly 33 and a positioning assembly 35. The drive assembly 31 is mounted on the frame 10. The blanking assembly 33 is connected to the drive assembly 31. The positioning assembly 35 is disposed adjacent to the driving assembly 31 and the blanking assembly 33. Referring to fig. 4, the driving assembly 31 includes a driving member 311, a driving wheel 312, a bearing seat 313, a rotating shaft 314, a driven wheel 315, and a transmission belt 316. The driving member 311 is fixed to the frame 10, and the driving wheel 312 is mounted on the driving end of the driving member 311. The bearing housing 313 is fixed to the frame 10, and the rotating shaft 314 is rotatably mounted to the bearing housing 313. The driven pulley 315 is fixed to one end of the rotating shaft 314. The belt 316 is disposed on the driving wheel 312 and the driven wheel 315. When the driving member 311 drives the driving wheel 312 to rotate, the driving wheel 312 drives the driven wheel 315 to rotate through the transmission belt 316, thereby driving the rotating shaft 314 to rotate. In this embodiment, the driver 311 is a motor.

Referring to fig. 5 and 6, the blanking assembly 33 is disposed near an end of the rotating shaft 314 away from the driven wheel 315. The cutting assembly 33 includes a first mounting member 331, a cutting blade set 333, a second mounting member 335, and a knife channel 337. The first mounting member 331 is fixedly mounted to an end of the rotating shaft 314 remote from the driven wheel 315. The blanking blade set 333 is fixed to the first mounting member 331. In the present embodiment, the cutter blade group 333 includes 5 cutter blades 3331. Each blanking blade 3331 is fixed perpendicular to the rotating shaft 314, and the cutting edge of each blanking blade 3331 is perpendicular to the rotating direction of the rotating shaft 314. In this embodiment, the 5 blanking blades 3331 are spirally spaced on the first mounting member 331, that is, the connecting line of the ends of the blanking blades 3331 is not parallel to the rotation axis direction of the rotation shaft 314, and the cutting edge directions of the blanking blades 3331 are not on the same plane. That is, the line connecting the ends of the 5-piece dicing blade 3331 is neither parallel nor perpendicular to the axis of the rotary shaft 314. The vertical distances between the 5-piece blanking blades 3331 are the same in the direction of the rotation axis of the rotation shaft 314. When the rotating shaft 314 rotates, the rotating shaft 314 drives the 5-piece slicing blade 3331 to rotate around the rotating shaft of the rotating shaft 314. The second mounting member 335 is secured to the frame 10 and the pocket 337 is secured to the second mounting member 335. The knife slot 337 is substantially cylindrical. The hollow portion of the knife channel piece 337 in the axial direction forms a feed channel 3371, and the feed channel 3371 is located directly below the feed channel 211 so that the feed roller 23 feeds the uncaria 200 from the feed channel 211 into the feed channel 3371. A knife groove 3373 corresponding to each of the cutting blades 3331 is concavely formed on the circumferential surface of the knife groove member 337 toward the axial direction of the vertical knife groove member 337 to such a depth that the knife groove 3373 completely includes the transverse section hole of the feed channel 3371. In the present embodiment, the number of the knife grooves 3373 is 5 so as to correspond one-to-one to each of the blanking blades 3331. The circumferential surface of the knife slot group 337 is concavely provided with a positioning groove 3375 along the axial direction of the vertical knife slot member 337, and the positioning groove 3375 is positioned between the first knife slot 3373 and the knife slot 3373 adjacent to the first knife slot 3373. The positioning groove 3375 is vertically communicated with the feeding channel 3371.

Referring to fig. 7-8, the positioning assembly 35 is disposed adjacent to the rotation shaft 314 and the knife slot 337. The positioning assembly 35 includes a pusher 351, a positioning member 352, and a chuck shaft 353. One end of the pushing element 351 is fixedly mounted on the rotating shaft 314, and drives the pushing element 351 to rotate around the rotating shaft 314 along with the rotating shaft 314 when the rotating shaft 314 rotates. The positioning member 352 is substantially L-shaped, one end of the positioning member 352 is rotatably mounted on the frame 10 through a clamping plate shaft 353, and the clamping plate shaft 353 and the knife groove 337 are located at two sides of the rotating shaft 314. A return spring (not shown) is provided in the chucking shaft 353. The positioning member 352 is recessed with a groove 3521 at an end thereof away from the chuck shaft 353. In this embodiment, when the return spring is in a natural state, the vertical distance between the positioning element 352 and the rotating shaft 314 is smaller than the distance from the pushing element 351 to the rotating shaft 314 away from the rotating shaft 314, one end of the positioning element 352 close to the groove 3521 is accommodated in the positioning slot 3375, and the gap formed between the groove 3521 and the positioning slot 3375 is smaller than the size of the hook 203 and larger than the size of the straight bar 201, so that the hook 203 cannot pass through but the straight bar 201 can pass through. In this embodiment, when the return spring is in a natural state, the gap formed between the groove 3521 and the positioning groove 3375 is defined as the limiting groove 301, and the limiting groove 301 is located right below the feeding channel 211. When the rotating shaft 314 rotates, the pushing element 351 is driven to rotate, and since the vertical distance between the positioning element 352 and the rotating shaft 314 is smaller than the distance from the pushing element 351 to the rotating shaft 314 from the rotating shaft 314, the pushing element 351 can push the positioning element 352 to move towards the direction away from the positioning slot 3375 after the pushing element 351 contacts the positioning element 352, so that the return spring is elongated. After the pushing element 351 rotates over the positioning element 352, the positioning element 352 returns to the natural state under the action of the return spring.

During assembly, the hopper 21 is fixedly mounted on the frame 10, the feeding roller 23 is rotatably mounted on the frame 10, the feeding roller 23 is partially accommodated in the hopper 21, and a feeding channel 211 is formed by a gap between the feeding roller 23 and the hopper 21. The driving member 311 and the bearing holder 313 are fixed to the frame 10. The drive wheel 312 is attached to the drive end of the drive member 311, and the rotating shaft 314 is rotatably attached to the bearing housing 313. The driven pulley 315 is fixed to one end of the rotating shaft 314, and the belt 316 is fitted over the driving pulley 312 and the driven pulley 315. The first mounting member 331 is fixed to the rotating shaft 314, and the 5-piece blanking blade 3331 is fixed to the first mounting member 331, and the blanking blade edge direction of each blanking blade 3331 is perpendicular to the rotating direction of the rotating shaft 314. The second mounting member 335 is fixed to the frame 10, the knife channel member 337 is fixed to the second mounting member 335 such that the feeding channel 3371 of the knife channel member 337 is positioned directly below the feeding channel 211, and each knife channel 3373 of the knife channel member 337 corresponds to a corresponding cutting blade 3331. The pushing element 351 is fixed on the rotating shaft 314, and one end of the positioning element 352 away from the groove 3521 is rotatably mounted on the frame 10 through the clamping plate shaft 353, and one end of the positioning element 352 close to the groove 3521 can selectively extend into the positioning slot 3375 of the knife slot element 337.

When the uncaria rhynchophylla feeding device is used, one end of the uncaria rhynchophylla 200 is placed into the feeding hopper 21, and the straight strips 201 of the uncaria rhynchophylla 200 enter the feeding channel 3371 from the feeding channel 211 under the action of the feeding roller 23. The driving member 311 drives the driving wheel 312 to rotate, and the driving wheel 312 drives the driven wheel 315 to rotate through the transmission belt 316, thereby driving the rotating shaft 314 to rotate. When the rotating shaft 314 rotates, the material cutting blade set 333 and the pusher 351 rotate in the rotating shaft direction of the rotating shaft 314 as the rotating shaft 314 rotates. When the hook 203 of the hook 200 is sent to the positioning slot 3375, the return spring is in a natural state, the pushing element 351 does not push the positioning element 352, the groove 3521 is accommodated in the positioning slot 3375, and a limiting groove 301 is formed between the groove and the positioning slot 3375, at this time, the straight bar 201 can pass through the limiting groove 301, and the hook 203 cannot pass through. When the hook 203 of the uncaria hook 200 is sent to the positioning groove 3375, the uncaria hook 200 is snap-positioned because the hook 203 of the uncaria hook 200 cannot pass through the stopper groove 301. The rotation of the rotating shaft 314 rotates the cutter blade set 333, so that each cutter blade 3331 cuts the straight strip 201 of the uncaria rhynchophylla 200. Since the positioning groove 3375 is located between the first knife slot 3373 and the knife slot 3373 adjacent to the first knife slot 3373, the first cutting blade 3331 and the adjacent cutting blade 3331 are cut off the straight strips 201 on both sides of the hook 203 which are positioned by the limiting groove 301 in a snapping manner. After the blanking blade group 333 performs blanking, the cut straight bar 201 falls. Referring to fig. 8 again, after the material cutting is completed, the rotating shaft 314 continues to drive the material cutting blade 3331 and the pushing element 351 to rotate, when the rotating shaft 314 drives the pushing element 351 to rotate until the pushing element 351 contacts the positioning element 352, because the vertical distance between the positioning element 352 and the rotating shaft 314 is smaller than the distance between the pushing element 351 and the rotating shaft 314 far away from the rotating shaft 314, the pushing element 351 pushes one end of the positioning element 352 close to the groove 3521 to move towards the direction far away from the positioning slot 3375, so that the gap between the groove 3521 and the positioning slot 3375 is increased until the gap between the groove 3521 and the positioning slot 3375 is larger than the size of the hook 203, and the cut hook 203. When the rotating shaft 314 rotates the pushing member 351 past the positioning member 352, the pushing member 351 no longer pushes the positioning member 352. At this time, under the action of the return spring, the positioning element 352 returns to the natural state, the end of the positioning element 352 close to the groove 3521 is accommodated in the positioning groove 3375 again, and the limiting groove 301 is formed between the groove 3521 and the positioning groove 3375 again. The straight strips 201 of the rest uncaria 200 are sent into the feeding channel 3371 again by the feeding roller 23 until the hook part 203 is buckled and positioned by the limiting groove 301, the rotating shaft 314 drives the material cutting blade set 333 to cut the uncaria 200 again, and the cut straight strips 201 fall off. The pushing member 351 pushes the positioning member 352 to move away from the positioning groove 3375, and the cut-off hook portion 203 drops. The above-mentioned material cutting steps are repeated, so that all the uncaria 200 are completely cut by the material cutting assembly 33.

The groove 3521 of the positioning element 352 in the blanking device 100 of the present embodiment can be selectively received in the positioning slot 3375, and when the groove 3521 of the positioning element 352 is received in the positioning slot 3375, a spacing groove 301 is formed between the groove 3521 and the positioning slot 3375. The size of the limiting groove 301 is not enough for the hook part 203 of the uncaria 200 to pass through and the straight strip 201 to pass through, so that when the groove 3521 of the positioning piece 352 is accommodated in the positioning groove 3375, the uncaria 200 can be automatically positioned, and when the uncaria 200 is in a positioning state, the straight strip 201 of the uncaria 200 is cut off by the cutting blade 3331. Further, when the groove 3521 of the positioning element 352 is received in the positioning slot 3375, a distance between an end of the pushing element 351 away from the rotating shaft 314 and the rotating shaft 314 is greater than a vertical distance between the positioning element 352 and the rotating shaft 314. After the material cutting is completed, the rotating shaft 314 drives the pushing element 351 to push the positioning element 352 to move, so that one end of the positioning element 352 close to the groove 3521 moves in a direction away from the positioning slot 3375, and thus a gap between the groove 3521 and the positioning slot 3375 is enlarged, so that the cut hook 203 can fall off. In the present embodiment, the 5-piece slitting blade 3331 is provided spirally on the first mounting fixture 331, so that the impact of the slitting blade 3331 on the straight bars 201 can be reduced at the same time.

The rotating shaft 314 drives the pushing element 351 to rotate, and when the pushing element 351 does not push the positioning element 352 to move in a direction away from the rotating shaft 314, one end of the positioning element 352 close to the groove 3521 is accommodated in the positioning slot 3375, so that the limiting groove 301 is formed between the groove 3521 and the positioning slot 3375. Since the size of the limiting groove 301 is not enough for the hook part 203 to pass through and the straight bar 201 to pass through, the uncaria 200 can be automatically positioned before the pushing part 351 pushes the positioning part 352 to move towards the direction far away from the rotating shaft 314, so that the blanking blade 3331 cuts off the straight bar 201 of the uncaria 200 when the uncaria 200 is in the positioning state.

It is understood that in other embodiments, the feeding assembly 20 may be omitted and the hooked member 200 is manually fed into the feeding channel 3371.

It is understood that in other embodiments, the belt 316 may be omitted, and in this case, the driving wheel 312 and the driven wheel 315 may be gears, and the driving wheel 312 may be engaged with the driven wheel 315.

It is understood that in other embodiments, the number of the blanking blades 3331 included in the blanking blade set 333 is not limited to 5 in this embodiment, and may be 2, 3, 4 or more than 5, and in this case, the knife grooves 3373 of the knife groove 337 correspond to the blanking blades 3331 one by one.

It is to be understood that in other embodiments, the first mounting member 331 may be omitted and the cutting blade set 333 may be directly fixed to the rotating shaft 314.

It will be appreciated that in other embodiments, the second mounting member 335 may be omitted and the knife slot 337 may be directly fixedly mounted to the frame 10.
