DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1 to Figure 5In an embodiment of the present invention, a raw material crushing device for carton production includes a base 1, a conveying bin 28 is fixedly installed on the top of the bottom plate of the base 1, the bottom end of the inner wall of the conveying bin 28 is flush with the top of the bottom plate of the base 1, a containing bin 2 is fixedly installed on the top of the conveying bin 28, the inner cavity of the containing bin 2 is connected with the inner cavity of the conveying bin 28, an auxiliary feeding mechanism is installed at the feed port of the base 1, and a lifting mechanism is connected at both ends of the auxiliary feeding mechanism through a telescopic component, the lifting mechanism is slidably connected to the base 1, the containing bin 2, and the conveying bin 28, a pushing mechanism is rotatably installed on the inner side of the lifting mechanism, the pushing mechanism is located in the inner cavity of the containing bin 2 and the conveying bin 28, and a crushing mechanism is installed at the end of the conveying bin 28.

[0019] In this embodiment: first, the peeled logs are placed on the top of the bottom plate of the base 1 and pushed forward. At this time, the auxiliary feeding mechanism is started. During the rotation process, the auxiliary feeding mechanism will press the upper periphery of the logs and perform circular rotation. After the logs are pressed, the logs can be hooked and moved toward the conveying bin 28. When the auxiliary feeding mechanism performs circular rotation, the lifting mechanism will be pulled upward synchronously by the auxiliary mechanism. The lifting mechanism moving upward drives the pushing mechanism to move upward synchronously. Therefore, the logs entering the conveying bin 28 will contact the bottom of the pushing mechanism. At this time, the running pushing mechanism applies a pushing force to the upper periphery of the logs. The pushing force pushes the logs toward the crushing mechanism and maintains the pushing force, prompting the crushing mechanism to crush the logs. After the logs completely enter the conveying bin 28, the auxiliary feeding mechanism is reset, and the lifting mechanism is kept at the current position, so that an uninterrupted pushing effect is achieved and continuous feeding can be achieved.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 The auxiliary feeding mechanism includes a rotating frame 3 rotatably installed on the top of the base 1, a rotating roller 4 is rotatably installed on the inner side of the vertical plate portion of the rotating frame 3, and a convex thorn 6 is integrally formed on the outer circumference of the rotating roller 4. A No. 1 motor 5 connected to one end of the rotating roller 4 is slidably installed on the outer side of the base 1, and a No. 1 protruding shaft 7 protruding outward is integrally formed on the end of the rotating roller 4 away from the No. 1 motor 5. A fixing hoop 35 is installed on the outer wall of the No. 1 motor 5, and a sliding seat 36 is fixedly connected to the bottom end of the fixing hoop 35. The outer wall of the sliding seat 36 is slidably connected to a guide seat 29 fixedly connected to the side wall of the base 1, and a tension spring 37 is abutted between the protruding portion at one end of the sliding seat 36 and the limiting portion at the opening of the guide seat 29.

[0021] In this embodiment: by starting the No. 1 motor 5, the No. 1 motor 5 drives the rotating roller 4 to rotate, and the convex thorns 6 on the outer periphery of the rotating roller 4 rotate synchronously. The rotating convex thorns 6 will hook the logs during the rotation process, and the logs pushed forward will push the rotating roller 4 and the convex thorns 6 upwards. At this time, the rotating roller 4 drives the rotating frame 3 to rotate with the rotating end of the rotating frame 3 as the center of the circle; When the rotating roller 4 revolves, the rotating roller 4 drives the sliding seat 36 at its bottom to slide along the inner wall of the guide seat 29 through the fixing hoop 35. During the sliding process of the sliding seat 36, the tension spring 37 changes from the stretched state to the normal state. Therefore, after the log is separated from the rotating roller 4, the rotating roller 4 that revolves and resets will stretch the normal tension spring 37, which can avoid collision caused by the rotating roller 4 resetting too quickly under gravity.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 The tops of the two vertical plates of the base 1 are integrally formed with an upper convex plate 8 protruding upward, and arc grooves 9 are opened inside the vertical plate part of the base 1 and the upper convex plate 8. The output shaft of the No. 1 motor 5 and the No. 1 protruding shaft 7 are movably connected to the inner sides of the two arc grooves 9 respectively, and the center of the arc groove 9 coincides with the rotation center of the rotating frame 3; the No. 2 protruding shaft 30 is fixedly installed on the tail end plate of the shell of the No. 1 motor 5.

[0023] In this embodiment, when the rotating roller 4 revolves, the rotating roller 4 drives the first protruding shaft 7 and the second protruding shaft 30 to rotate synchronously. At this time, the first protruding shaft 7 and the second protruding shaft 30 move along the arc groove 9.

[0024] Please refer to Figure 5 The telescopic assembly includes a sliding plate 10 which is rotatably mounted on the outer sides of the No. 1 protruding shaft 7 and the No. 2 protruding shaft 30 respectively. A sliding groove is provided inside the sliding plate 10, and a guide plate 38 is circumferentially slidably connected to the inner wall of the sliding groove.

[0025] In this embodiment: when the No. 1 protruding shaft 7 and the No. 2 protruding shaft 30 revolve, the sliding plates 10 of the No. 1 protruding shaft 7 and the No. 2 protruding shaft 30 move synchronously. Since the guide plate 38 limits the sliding plate 10, the No. 1 protruding shaft 7 and the No. 2 protruding shaft 30 can only pull the sliding plate 10 to slide in the sliding groove of the guide plate 38. While sliding axially, the sliding plate 10 moves upward, and the upward moving sliding plate 10 pulls the guide plate 38 to move upward synchronously.

[0026] Please refer to Figure 4The lifting mechanism includes a lifting plate 16 fixedly connected to one end of the guide plate 38, a vertical plate 19 is slidably connected to the outer wall of the lifting plate 16, a limiting groove 20 is vertically provided inside the vertical plate 19, and a limiting block 34 connected to the limiting groove 20 is integrally formed on the outer wall of the lifting plate 16, and a docking frame 17 is integrally formed on the lifting plate 16, and the cross section of the docking frame 17 is a "C"-shaped mechanism with an opening facing upward; the vertical plate 19 is fixedly connected to the outer side wall of the base 1 and the conveying bin 28, and the lifting mechanism also includes a card connected to the inner wall of the docking frame 17 The docking blocks 15 are fixedly connected with the force-bearing plates 14 on the tops of the two docking blocks 15. The two ends of the tops of the force-bearing plates 14 are welded with upwardly protruding sliding shafts 12. The outer wall of the sliding shaft 12 is slidably connected with a fixed plate 11 fixedly connected to the outer walls of the accommodating bin 2 on both sides. The bottom end of the fixed plate 11 and the top end of the force-bearing plates 14 are directly abutted with a return spring 13. The return spring 13 is sleeved on the outer wall of the sliding shaft 12. Vertical grooves 21 are provided on the base 1, the accommodating bin 2 and the conveying bin 28 for the shaft bodies at both ends of the tensioning roller 32 to slide up and down.

[0027] In this embodiment: when the guide plate 38 is upward, the guide plate 38 drives the lifting plate 16 connected thereto to move synchronously, and the lifting plate 16 drives the limit block 34 to slide upward along the inner wall of the limit groove 20. At this time, the lifting plate 16 pushes the force plate 14 to move upward, and the force plate 14 moving upward drives the sliding shaft 12 to move synchronously. At this time, the return spring 13 is compressed, and the lifting plate 16 moving upward pushes the docking block 15 to move upward through the docking frame 17, and the docking block 15 can drive the pushing mechanism to move upward; The above method realizes the synchronous and equidistant movement of the pushing mechanism and the auxiliary feeding mechanism in the vertical direction; After the logs are separated from the auxiliary feeding mechanism and completely enter the conveying bin 28, the auxiliary feeding mechanism is reset under gravity. At this time, the pushing mechanism is pressed against the top of the logs, and the compressed reset spring 13 applies a downward reset force to the pushing mechanism. The pushing mechanism can effectively push the logs in the conveying bin 28, and the reset auxiliary feeding mechanism will not drive the pushing mechanism to reset synchronously.

[0028] Please refer to Figure 3 The pushing mechanism includes a tensioning roller 32 rotatably mounted with the docking block 15, a pushing belt 33 is transmission-connected between the two tensioning rollers 32, a No. 2 motor 18 is mounted on the outer side of the force-bearing plate 14 through a bracket, and the output shaft of the No. 2 motor 18 is coaxially fixedly connected to one end of a tensioning roller 32.

[0029] In this embodiment: by starting the second motor 18, the second motor 18 drives a tensioning roller 32 connected thereto to rotate, and the tensioning roller 32 drives another tensioning roller 32 to rotate synchronously through a push belt 33. The push belt 33 drives the logs to move toward the crushing mechanism during the transmission process.

[0030] Please refer to Figure 3 The crushing mechanism includes a crushing bin 22 fixedly connected to the end of the conveying bin 28, the inner cavity of the conveying bin 28 is connected to the inner cavity of the crushing bin 22, and a No. 3 motor 24 is installed on the outer wall of the crushing bin 22 through a bracket. A large pulley 25 is fixedly connected to the output end of the No. 3 motor 24, and the large pulley 25 is connected to a small pulley 27 through a belt 26. One end of the small pulley 27 is coaxially connected to a synchronous shaft, which passes through the inner cavity of the crushing bin 22 and is connected to a crushing grinding disc 31. The synchronous shaft is rotatably connected to the crushing bin 22 through a bearing, and a discharge bin 23 is installed below the end of the crushing bin 22.

[0031] In this embodiment: start the No. 3 motor 24, the No. 3 motor 24 drives the large pulley 25 to rotate, and the large pulley 25 drives the small pulley 27 to rotate synchronously through the belt 26. Since the size of the small pulley 27 is smaller than that of the large pulley 25, the transmission is a speed-increasing transmission, so that the high-speed rotation of the crushing grinding disc 31 is realized. When one end of the log moving toward the crushing mechanism contacts the crushing surface (the crushing surface is formed with crushing teeth) of the crushing grinding disc 31, the high-speed rotating crushing teeth can crush the log, and the wood chips formed after crushing are discharged outward through the discharge bin 23.

[0032] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
