[0002] The material pushing mechanism of a sheet arranging machine is a key component in the sheet arranging machine for pushing the sorted materials (such as punching sheets, papers, etc.) away from the working area or pushing them to the next process.

[0003] The existing patent (publication number: CN112357361A) discloses "The present invention discloses a storage device with a sheet arranging function in a sanitary product production line, including a bracket, a quality inspection mechanism, a sheet arranging mechanism, a thermal circulation sterilization mechanism, and a quantitative storage mechanism.

Both sides of the inclined platform are respectively fixed on the bracket. The inclined platform is arranged above the transportation tray, and the fan is located above the inclined platform."

[0004] The inventor found in the process of implementing the present application that the existing material pushing mechanism of the sheet arranging machine is a reciprocating type. The motor and the cylinder jointly complete a material pushing action, driving the push plate to do reciprocating motion. The existing structure is relatively complex, the mechanical structure is inconvenient to adjust, and the electrical program is cumbersome. The main disadvantage is that the speed is slow, there will be waiting time during the material pushing process, affecting the beat of the whole machine, resulting in low production capacity. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a circulating material pushing mechanism for a sheet arranging machine, which greatly improves the speed, has a simple structure, and makes its debugging and production more efficient and fast.

[0006] To achieve the above objectives, the present invention is realized through the following technical solutions: A circulating material pushing mechanism for a sheet arranging machine includes two support square steels. Two circulating material pushing machine frames are fixedly arranged at the upper ends of the two support square steels. Two cross beams are fixedly arranged on the upper surface of the circulating material pushing machine frame. Reducer mounting plates are fixedly arranged at positions on the outer sides of the two cross beams that are relatively middle and biased towards both ends; First fixing plates are fixedly arranged at positions on the inner sides of the two cross beams that are relatively middle and biased towards both sides. Second fixing plates are fixedly arranged at both ends of the inner sides of the two cross beams. A driving gear set is connected between the multiple second fixing plates.

[0007] Preferably, a speed reducer is fixedly arranged on the surface of each of the plurality of speed reducer mounting plates, and a servo motor is fixedly arranged at one end of each of the plurality of speed reducers.

[0008] Preferably, expansion sleeves are fixedly arranged at the output ends of the plurality of servo motors and one ends of the driving gear sets, a synchronous pulley is fixedly arranged on the outer surface of each expansion sleeve, and a synchronous belt is arranged on the surfaces of the plurality of synchronous pulleys.

[0009] Preferably, transfer wheels are arranged on the surfaces of each of the plurality of first fixing plates and second fixing plates, and two pusher chains are arranged on the surfaces of the plurality of transfer wheels.

[0010] Preferably, the pusher chain comprises a double-row chain, a plurality of chain blocks are fixedly arranged on the surface of the double-row chain, and a bearing is fixedly arranged at one end of each of the plurality of chain blocks.

[0011] Preferably, a pusher plate mounting block is rotatably arranged at one end of each of the plurality of chain blocks through a bearing, and a pusher plate is fixedly arranged on one side of each of the plurality of pusher plate mounting blocks.

[0012] Preferably, the driving gear set comprises a driving shaft, and cylindrical gears are fixedly arranged at both ends of the driving shaft.

[0013] Preferably, the transfer wheel is composed of a combination of a gear and a sprocket.

[0014] Working principle: When the mechanism is in use, the servo motor is fixed on the cross beam through the speed reducer mounting plate. The output end of the servo motor is connected to the synchronous pulley through an expansion sleeve, and the synchronous pulley is connected to the synchronous pulley of the driving gear set through a synchronous belt to provide power for the entire device. After the servo motor is started, the driving shaft of the driving gear set is driven to rotate through the synchronous belt. The cylindrical gears at both ends of the driving shaft are meshed with the gear part of the transfer wheel to transmit the rotational power to the transfer wheel. The sprocket part of the transfer wheel is connected to the pusher chain to convert the rotation of the gear into the movement of the chain. The pusher chain is composed of a double-row chain, and a plurality of chain blocks are fixed on the chain. The chain blocks are connected to the pusher plate mounting blocks through bearings, and a pusher plate is fixed on the pusher plate mounting blocks. When the double-row chain moves, the pusher plate makes a reciprocating motion driven by the chain. Since the pusher plate is connected through a bearing, the pusher plate always remains vertical under the action of the staggered chain. During the cyclic movement of the pusher plate, the sorted materials are pushed out of the working area or pushed to the next process.

[0015] The present invention provides a cycle pusher mechanism for a tablet sorting machine. It has the following beneficial effects: The present invention provides a circulating feeding mechanism for a sheet arranging machine. Compared with the existing feeding mechanism of the sheet arranging machine, this circulating feeding mechanism of the sheet arranging machine adopts a mechanical transmission method combining a servo motor with a synchronous belt and a sprocket gear, as well as a chain staggered arrangement transmission method. The push plate always maintains a vertical state and realizes reciprocating motion, greatly improving the feeding speed. The circulating feeding mechanism adopts continuous circular motion, avoiding the waiting time when the motor and the cylinder jointly complete a feeding action in the traditional reciprocating feeding mechanism, significantly improving the beat and production capacity of the whole machine. At the same time, the design of this mechanism is more concise than the traditional reciprocating feeding mechanism, reducing the complexity of the mechanical structure and lowering the debugging difficulty and maintenance cost.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Such as Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention provides a circulating feeding mechanism for a slicing machine, which includes two support square steels 7. At the upper ends of the two support square steels 7, a circulating feeding machine frame 1 is fixedly arranged. On the upper surface of the circulating feeding machine frame 1, two cross beams 8 are fixedly arranged. At the positions of the two cross beams 8 that are relatively outer and in the middle and biased towards both ends, speed reducer mounting plates 9 are fixedly arranged. At the positions of the two cross beams 8 that are relatively inner and in the middle and biased towards both sides, first fixing plates 10 are fixedly arranged. At both ends of the two cross beams 8 that are relatively inner, second fixing plates 11 are fixedly arranged. A driving gear set 3 is connected between the multiple second fixing plates 11.

[0020] Specifically, the support square steel 7 is fixedly connected to the circulating feeding machine frame 1 through bolts. The cross beam 8 is fixed on the support square steel 7. The speed reducer mounting plate 9 is installed on the cross beam 8. The first fixing plate 10 and the second fixing plate 11 are also installed on the cross beam 8. Multiple structures are combined with each other to form the overall platform of the mechanism, providing a support basis for the use of this structure.

[0021] As Figure 1 and Figure 3 shown, conversion wheels 4 are arranged on the surfaces of multiple first fixing plates 10 and second fixing plates 11. Two pushing chains 2 are arranged on the surfaces of the multiple conversion wheels 4. The pushing chain 2 includes a double-row chain 12. A plurality of chain blocks 13 are fixedly arranged on the surface of the double-row chain 12. At one end of each of the plurality of chain blocks 13, a bearing 14 is fixedly arranged. At one end of each of the plurality of chain blocks 13, a push plate mounting block 15 is rotatably arranged through the bearing 14. On one side of each of the plurality of push plate mounting blocks 15, a push plate 16 is fixedly arranged.

[0022] Specifically, the two groups of double-row chains 12 are cross-connected. One end of the chain block 13 is fixed on the double-row chain 12, and the other end is connected to the push plate mounting block 15 through the bearing 14. The push plate 16 is installed on the push plate mounting block 15. When the double-row chain 12 rotates, the push plate 16 makes a reciprocating circular motion driven by the double-row chain 12. And the push plate 16 rotates through the bearing 14 and always maintains a vertical motion state under the action of gravity, realizing the feeding function of the mechanism.

[0023] As Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, speed reducers are fixedly arranged on the surfaces of multiple speed reducer mounting plates 9. At one end of each of the multiple speed reducers, a servo motor 6 is fixedly arranged. At the output ends of the multiple servo motors 6 and one end of the driving gear set 3, expansion sleeves 20 are fixedly arranged. On the outer surface of the expansion sleeve 20, a synchronous pulley 19 is fixedly arranged. A synchronous belt 5 is arranged on the surfaces of the multiple synchronous pulleys 19. The driving gear set 3 includes a driving shaft 17, and cylindrical gears 18 are fixedly arranged at both ends of the driving shaft 17.

[0024] Specifically, both ends of the driving shaft 17 are connected to the first fixing plate 10 through pedestal bearings. The cylindrical gear 18 is tightly held on the driving shaft 17. The synchronous pulley 19 is connected to the driving shaft 17 through a shrink disc 20, driving the cylindrical gear 18 to rotate together. On the other side of the synchronous pulley 19, it is connected to the synchronous pulley 19 at the output end of the servo motor 6 through a synchronous belt 5, providing the power source for the rotation of the entire device.

[0025] As Figure 6 shown, the conversion wheel 4 is composed of a gear and a sprocket.

[0026] Specifically, the gear of the conversion wheel 4 is connected to the cylindrical gear 18 of the driving gear set 3, and the sprocket of the conversion wheel 4 is connected to the double-row chain 12. When in use, the conversion wheel 4 can convert the rotation of the gear into the rotation of the sprocket. By driving the synchronous pulley 19 to rotate through the servo motor 6, the cylindrical gear 18 at one end of the driving shaft 17 is driven to rotate. Through the transmission between the cylindrical gear 18 and the gear of the conversion wheel 4, the sprocket of the conversion wheel 4 is driven to rotate, and then the double-row chain 12 is driven to move, thereby realizing the function of driving the entire mechanism to rotate and push materials.
