Specifically, a mounting plate 120 and a plurality of supporting columns 130 are provided, one end of each supporting column 130 is fixed on the carrier table 110, the other end of each supporting column 130 is connected with the mounting plate 120 and supports the mounting plate 120, and the mounting plate 120 is located above the blanking portion 102 and the loading portion 101. The first driving member 42 is mounted on the mounting plate 120 on the frame 10 such that the blanking blade 41 is disposed above the blanking portion 102.

The first driving member 42 drives the cutting blade 41 to reciprocate toward the blanking portion 102 to blank the material at the blanking portion 102. Obviously, the blanking device 40 including the first driving member 42 automates the blanking process, saving labor and increasing efficiency. The first driving member 42 is also electrically connected to a controller such as a PLC or an industrial personal computer.

It is worth mentioning that the sandpaper may be provided with a stopper 140 at both sides of the path from the loading portion 101 to the blanking portion to prevent the sandpaper from deviating from the path.

Referring to fig. 2, 3 and 5, the blanking portion 102 is provided with a blanking hole 1021, and the blanking hole 1021 is a hole penetrating through the plate-shaped jig on the supporting stage 110 and the supporting stage 110 itself. In some embodiments, the material cutting blade 41 has a first end 411 and a second end 412 disposed oppositely, the first end 411 is connected to the first driving member 42, the second end 412 may be configured as a cylindrical opening edge, the material cutting blade 41 is disposed above the blanking hole 1021, and the second end 412 is aligned with the blanking hole 1021. Obviously, the outer ring capable of cutting circular materials conveniently is arranged.

Specifically, the material is pushed above the blanking hole 1021 by the pushing member 31, the cutting blade 41 is driven by the first driving member 42 to move towards the blanking hole 1021, the cutting blade 41 cuts the material and at least partially extends into the blanking hole 1021, and when the cutting blade 41 is cylindrical, the material can be cut into an inner round material and an outer ring excess material. The inner round material is a desired material, and falls from the bearing table 110 through the blanking hole 1021, and the outer ring remainder remains in the blanking portion 102, thereby completing cutting of the material. And after the pushing piece 31 pushes new materials into the blanking part 102, the outer ring excess materials are pushed out by the new materials. Therefore, the recycling box 150 is arranged below the blanking hole 1021 and the outer ring excess material pushed out side (the side of the blanking part 102 away from the loading part 101) to recycle the needed material and excess material.

It is worth mentioning that one end of the blanking hole 1021 deviating from the material cutting knife 41 can be further arranged to be an outward flaring, so that blanking of inner ring materials is facilitated, and the risk that the inner ring materials are blocked in the blanking hole 1021 is reduced.

In addition, a downwardly inclined chute 160 may be further disposed on a side of the blanking portion 102 facing away from the loading portion 101, and the chute 160 is used for guiding the outer ring excess to the recycling bin 150.

In some embodiments of the present application, referring to fig. 1 and 2, the barrel 21 is disposed above the loading portion 101. Specifically, the cartridge 21 is disposed above the loading section 101 by mounting the cartridge 21 on the support plate.

The material inlet 211 and the material outlet of the charging barrel 21 are oppositely arranged, and the material outlet is close to the material loading part 101 relative to the material inlet 211. That is, the inlet 211 is located above the outlet, and the sandpaper falls from the outlet under the action of gravity after the inlet 211 enters the barrel 21. The discharge port is aligned with the material loading part 101, and the sandpaper falls on the material loading part 101 after falling.

It should be noted that the gap between the discharge port and the loading portion 101 is the thickness of one piece of sandpaper, so that when there are a plurality of sandpapers in the cylinder 21, the lowest sandpaper falls on the loading portion 101, and the rest of the sandpaper is pressed on the sandpaper in the loading portion 101 and is located in the cylinder 21, and after the lowest sandpaper is pushed away, the next piece of sandpaper falls into the blanking portion 102, so that the loading can be completed by gravity, and the loading process is simple and energy-saving. Of course, in other embodiments, the gap between the outlet and the loading portion 101 may be greater than the thickness of one piece of sandpaper, and a cover may be provided to cover the outlet to prevent all of the remaining sandpaper from leaking out of the cartridge 21.

In view of the fact that the material itself is lighter in weight, or the amount of material is smaller, the material located below is subjected to less pressure. Further, referring to fig. 1 and 2, the feeding device 20 further includes a connecting strip (not shown) and a pressing member 22, one end of the connecting strip is connected to one end of the barrel 21 provided with the feeding port 211, and the other end of the connecting strip is connected to the pressing member 22. After the material is placed in the barrel 21, the pressure member 22 is placed directly on the uppermost material, adding a downward pressure to the entire material. After all materials are discharged from the discharge hole, the pressing piece 22 cannot be discharged from the discharge hole due to the connection effect of the connecting strip. At this point, the operator may pull the hold-down 22 up through the connecting strip.

It should be noted that the connecting strip may be made of metal materials such as iron wires and copper wires, or may be made of non-metal materials such as plastic and plastics, and is not limited herein. The binder 22 may be a copper block, an iron block, a stone block, a wood block, a plastic block, etc., which are not listed here.

In some embodiments of the present application, referring to fig. 1 and fig. 2, the pushing device 30 includes a pushing member 31 and a second driving member 32, the pushing member 31 is connected to the second driving member 32, and the second driving member 32 is mounted on the carrying platform 110 of the frame 10 or a plate-shaped fixture mounted on the carrying platform 110. The second drive member 32 is provided as a pneumatic or hydraulic cylinder, both having a piston rod, to which the push member 31 is connected. When the air cylinder or the hydraulic cylinder works, the piston rod can drive the pushing piece 31 to reciprocate, so that the material of the material loading part 101 can be pushed to the blanking part 102. Obviously, the pushing device comprising the second driving member 32 can automate the process of pushing material, thereby saving labor and improving efficiency. Of course, a PLC (Programmable Logic Controller), an industrial personal computer, or other control device electrically connected to the second driving element 32 may be correspondingly installed on the rack 10 to control the operation of the second driving element 32. In addition, a sensor 60 may be provided at the loading portion 101 to identify whether the loading portion 101 is loaded. Thereby judging whether the material is used up and whether the material is blocked.

In other embodiments, the second driving member 32 may also be a mechanical arm, and the pushing member 31 can be driven by the mechanical arm to reciprocate or otherwise move in an irregular path.

It is worth mentioning that the contact part of the pushing piece 31 and the material can be arranged according to the shape of the material in a profiling mode, so that the material can be limited to a certain extent, and the risk of material deviation in the pushing process is reduced. For example, the material is circular sand paper, the pushing member 31 is configured as a pushing plate, and one end of the pushing plate, which is in contact with the material, is concavely configured into an arc shape.

With reference to fig. 1 and fig. 2, in combination with the above embodiment, the second driving member 32 is configured as an air cylinder or a hydraulic cylinder, the pushing member 31 and the second driving member 32 are disposed on one side of the blanking portion 102, and the material loading portion 101 is disposed between the pushing member 31 and the blanking portion 102.

It should be noted that, in the present embodiment, when the pushing member 31 pushes the material to leave the material loading portion 101, a part of the pushing member 31 is located in the material loading portion 101 and can block the material outlet, and the material located in the lowest layer in the barrel 21 falls on the pushing member 31. The pusher 31 is provided as a plate-like member that can better block the discharge port, and prevent the material from being exposed from the barrel 21 at this time and from rolling off the position outside the loading portion 101.

Since some materials contain fibers or other materials that are not suitable for cutting, the stroke of the cutter 41 is ensured to be long enough. On the basis, in order to reduce the shaking and deviation of the material cutting blade 41 during the operation process, referring to fig. 4, the material cutting device 40 further includes a guide block 43, the guide block 43 is mounted on the mounting plate 120 on the frame 10, a guide groove 413 is concavely provided on at least one side of the material cutting blade 41, the guide groove 413 extends along the direction that the material cutting blade 41 is close to or far away from the material dropping hole 1021, and the guide groove 413 and the guide block 43 are in limit fit.

In some embodiments of the present application, referring to fig. 5, the second end 412 of the blade 41 is a blade with a cylindrical opening, and the opening edge of the second end 412 is disposed in a wave shape. The cutter with the common circular cutting edge is in contact with materials integrally, the wave crests of the wave-shaped cutting edge of the cutting cutter 41 with the shape are in contact with the materials firstly, the initial contact area is small, the pressure applied to the materials by the cutting cutter 41 is large at the moment, and the materials in contact with the wave crest cutting edge can be cut off firstly, so that the whole punching process is smoother, and the punching effect is better.

It should be understood that the wave-shaped cutter may have a smooth transition arc shape or a folded angle shape, and is not limited in this respect.

Further, with reference to fig. 5, the outer peripheral edge of the second end portion 412 is adjacent to the blanking portion 102 compared to the inner peripheral edge of the second end portion 412, and a rib is protruded on a connecting surface of the outer peripheral edge of the second end portion 412 and the inner peripheral edge of the second end portion 412. When the cutter is arranged in this way, the inner side edge of the cylindrical cutting knife 41 has a material rejecting effect, namely, the material is not easy to extrude and clamp on the inner side of the cylindrical cutting knife 41, so that the cutter is beneficial to long-term use, and a large amount of maintenance time is saved.

In some embodiments of the present application, referring to fig. 2 to 4, the blanking apparatus 100 further includes a material fixing device 50, and the material fixing device 50 includes a pressing block 51 and a third driving member 52. The pressing block 51 and the third driving member 52 are connected and located above the blanking portion 102, and the third driving member 52 is mounted on a mounting plate 120 on the frame 10 and drives the pressing block 51 to move toward or away from the blanking portion 102.

The number of the pressing blocks 51 may be one or more. When the pressing block 51 is arranged as one, a hole for avoiding the cutter 41 is formed in the middle. When a plurality of press blocks 51 are provided, they may be uniformly arranged on the peripheral side of the material cutting blade 41, or a plurality of press blocks 51 may be stacked and connected, and are not particularly limited herein.

It should be noted that, a guide pin 53 may be further disposed on the bearing table 110 or the mounting plate 120, a guide hole 54 is correspondingly disposed on a surface of the pressing block 51 facing the guide pin 53, and the guide pin 53 extends into the guide hole 54 to be in limit fit with the guide hole 54, so as to reduce offset and shaking of the pressing block 51 during the movement process.

In the present application, a plurality of pieces of circular sandpaper are put into the barrel 21 from the material inlet 211, and the material located at the lowermost layer falls onto the material loading portion 101 from the material outlet 212. The holder 22 is placed on the uppermost sand paper of the barrel 21 to hold the sand paper. The second driving member 32 is controlled by a control device such as a PLC to operate, and the second driving member 32 drives the pushing member 31 to move, so that the pushing member 31 pushes the sandpaper on the loading portion 101 to a position above the blanking hole 1021 of the blanking portion 102. At this time, the pusher 31 passes through the loading portion 101 and blocks the discharge port 212, and the sandpaper in the cartridge 21 falls onto the pusher 31. The second driving member 32 then controls the pushing member 31 to return to the original position, and when the pushing member 31 is withdrawn from the loading portion 101, the discharge port 212 is opened, and new sandpaper falls onto the loading portion 101 from the discharge port 212 of the cartridge 21. The sensor 60 provided in the loading portion 101 detects whether the sandpaper of the loading portion 101 is in place.
