[0020] According to the above technical solution, the inner gear ring 56 rotates in the grinding cylinder 2, thereby driving the plurality of auxiliary grinding rollers 26 to move in the circumferential direction in the grinding cylinder 2. When the gear plate 50 rotates, the reverse gear 58 is driven to rotate in the reverse direction through the coaxial reverser, thereby driving the plurality of ring gears 57 to rotate, and further driving the plurality of auxiliary grinding rollers 26 to rotate. When the auxiliary grinding rollers 26 rotate, the grinding blocks 48 can continuously grind the particle raw materials in the inner groove of the grinding cylinder 2, and grind synchronously with the arc groove on the main grinding roller 25. After the ground particle materials reach a certain uniformity, they flow to the bottom, and then the external controller automatically opens the discharge valve, so that the mixed materials are discharged from the discharge valve. The material transfer channel 24 between the grinding cylinder 2 and the screw conveyor 3 flows back into the grinding cylinder 2 and is circulated and transported to the screw conveyor 3 for further grinding. After grinding for a predetermined time, the switch of the first hydraulic push rod 12 is turned on from the external controller, and the first hydraulic push rod 12 extends to drive the discharge plate 61 to slide out of the grinding cylinder 2, releasing the ground raw material into the silo 49, and is pushed into the former 4 through the pushing mechanism to form a cylindrical shape. The third servo motor 8 is turned on by the external controller to drive the winding drum 16 to rotate, thereby winding the core wire. When the winding is completed, the switch of the micro push rod 30 is turned on from the external controller, and the micro push rod 30 retracts. The guide frame 33 is driven to slide on the opening strip 17, thereby clamping the core wire at the tail, and then the first servo motor 21 and the third servo motor 8 are controlled to rotate synchronously. When the first servo motor 21 rotates, the pinion drives the turntable 31 to rotate clockwise, thereby driving the turntable 32 to rotate, further driving the opening strip 17 and then driving the guide frame 33 to rotate, so that the winding drum 16 and the guide frame 33 rotate synchronously to the direction of the corrugated material plate 22. When the guide frame 33 rotates to the top of the corrugated material plate 22, the micro push rod 30 is extended again to open the guide frame 33 so that the pencil lead faces upward, and then the winding drum 16 is reversed so that the pencil lead faces upward. The pencil lead wire is fed onto the corrugated material plate 22, and is driven by the first belt drive 27 to run in the conveyor 20. When the lead wire reaches the predetermined position, the second hydraulic push rod 18 operates to push the cutting blade 23 to position and cut the lead wire. The cut pencil lead enters the discharge hopper 15, and is slightly sorted. When it reaches the predetermined amount, the external controller turns on the second servo motor 37 to drive the connecting rod 60 to rotate a predetermined angle, so that the swing bridge 36 is driven to swing, and the pull rod 38 is driven to move during the swing, thereby driving the second vertical plate 35 to deliver a certain amount of lead, and the first vertical plate 34 is intercepted again, so as to achieve the purpose of quantitative collection and packaging.
[0021] A further technical solution is that the feeding assembly 553 includes a screw conveyor 3 fixedly mounted on the outer surface of the grinding cylinder 2, a feed hopper 19 is connected to one side of the screw conveyor 3, a material transfer channel 24 is commonly connected between the bottom end of the grinding cylinder 2 and the screw conveyor 3, a second belt drive 59 is commonly installed on the output shaft of the main drive motor 13 and the screw conveyor 3, a first hydraulic push rod 12 is fixedly mounted on the outer surface of the grinding cylinder 2, a discharge plate 61 is inserted into the bottom end of the grinding cylinder 2, and the first hydraulic push rod 12 is fixedly connected to the discharge plate 61.
[0022] According to the above technical solution, the external mixed raw materials are put into the screw conveyor 3 from the feed hopper 19, and the main drive motor 13 runs the output shaft to drive the second belt drive 59 to operate, so that the screw conveyor 3 starts to transport the mixed granular raw materials into the grinding cylinder 2. The operation of the main drive motor 13 drives the gear plate 50 to rotate, which helps to circulate the material and ensure the grinding effect.
[0023] A further technical solution is that the center-split molding component 554 includes a swing frame 39 slidably mounted on the upper part of the frame 1, and sliders 41 are slidably mounted on both sides of the swing frame 39, and the corresponding sides of the two sliders 41 are commonly connected to the cutting piece 40, and the other sides of the two sliders 41 are fixedly connected to the vertical rack plate 45, one side of the swing frame 39 is rotatably connected to the shaft rod 42, and the outer surface of the shaft rod 42 is fixedly covered with a plurality of linkage gears 44, and one side of the swing frame 39 is rotatably connected to the bevel rack plate 43, and a baffle rod 62 is arranged on the upper part of the frame 1, and the middle linkage gear 44 is meshed with the bevel rack plate 43, and a baffle rod 62 matching the bevel rack plate 43 is arranged on the upper part of the frame 1, and an insertion rod 46 is fixedly connected to both sides of the swing frame 39, and a spring 47 is covered on the outer surface of the insertion rod 46.
[0024] According to the above technical solution, after the columnar material is extruded, the swing frame 39 is pushed to move, so that the oblique rack plate 43 is driven to slide on the blocking rod 62, thereby driving the middle linkage gear 44 to rotate, and further driving the shaft rod 42 to rotate while being able to drive the other two linkage gears 44 to rotate counterclockwise, thereby driving the vertical rack plate 45 to descend, so that the slider 41 is driven to slide downward on the swing frame 39. After sliding, the cutting piece 40 moves downward to punch the cylindrical material. The cut material falls into the transfer rack 9 from the opening plate 29, first contacts the receiving plate 28 and acts on the spring retractor 10, thereby adjusting the fallen material to fall smoothly into the placement channel 11, and the compressor 6 is controlled to operate by an external controller, so that the cylindrical material is fed into the wire-out machine 7 to be formed into colored pencil core wire, which is helpful for automatic cutting of the cylindrical material and improves the conveying efficiency.
[0025] The embodiment of the present invention also provides an automatic colored pencil lead cutting and grinding machine, and the specific working principle includes the following steps: The whole device is opened and operated by personnel, and the external mixed raw materials are put into the feed hopper 19 and enter the screw conveyor 3. The output shaft of the main drive motor 13 drives the second belt drive 59 to operate, so that the screw conveyor 3 starts to convey the mixed granular raw materials into the grinding cylinder 2. The operation of the main drive motor 13 drives the gear plate 50 to rotate, so that the internal gear ring 56 is driven to rotate in the grinding cylinder 2, thereby driving the multiple auxiliary grinding rollers 26 to move circumferentially in the grinding cylinder 2. When the gear plate 50 rotates, the reverse gear 58 is driven to rotate in the opposite direction through the coaxial reverser, thereby driving the multiple ring gears 57 to rotate, and further driving the multiple auxiliary grinding rollers 26 to rotate. When the auxiliary grinding rollers 26 rotate, the grinding blocks 48 can be placed in the inner grooves of the grinding cylinder 2. The granular raw materials are continuously ground inside, and are ground synchronously with the arc groove on the main grinding roller 25. After the granular materials to be ground reach a certain uniformity, they flow to the bottom, and then the external controller automatically opens the discharge valve, so that the mixed materials flow back into the grinding cylinder 2 from the transfer channel 24 between the grinding cylinder 2 and the screw conveyor 3, and are circulated and transported to the screw conveyor 3 for further grinding. After grinding for a predetermined time, the switch of the first hydraulic push rod 12 is turned on from the external controller, and the first hydraulic push rod 12 extends to drive the discharge plate 61 to slide out of the grinding cylinder 2, releasing the ground raw materials into the silo 49, and is pushed into the former 4 to form a cylindrical shape through the pushing mechanism. When the columnar material is extruded, it pushes the swing frame 39 to move, so that the inclined rack plate 43 is driven to slide on the stop rod 62, thereby driving The linkage gear 44 in the middle rotates, further driving the shaft 42 to rotate, and can drive the other two linkage gears 44 to rotate counterclockwise, thereby driving the vertical rack plate 45 to descend, so that the slider 41 is driven to slide downward on the swing frame 39. After sliding, the cutting piece 40 moves downward to punch the cylindrical material, and then quickly resets under the action of the spring 47. The cut material falls from the opening plate 29 into the transfer rack 9, first contacts the receiving plate 28 and acts on the spring retractor 10, so as to adjust the fallen material to fall smoothly into the placement channel 11, and the compressor 6 is controlled to operate by an external controller, so that the cylindrical material is fed into the wire-exiting machine 7 to be formed into colored pencil core wire, and the third servo motor 8 is turned on by the external controller to drive the winding drum 16 to rotate. The micro push rod 30 is turned on and off by the external controller. The micro push rod 30 is contracted to drive the guide frame 33 to slide on the opening strip 17, thereby clamping the core wire at the tail. Then the first servo motor 21 is controlled to rotate synchronously with the third servo motor 8. When the first servo motor 21 rotates, the pinion drives the turntable 31 to rotate clockwise, thereby driving the turntable 32 to rotate, further driving the opening strip 17 and then driving the guide frame 33 to rotate, so that the winding drum 16 rotates synchronously with the guide frame 33 to the direction of the corrugated material plate 22. When the guide frame 33 rotates to the top of the corrugated material plate 22, the micro push rod 30 is extended again to open the guide frame 33 so that the pencil lead faces upward, and then the winding drum 16 is reversed.The pencil lead wire is fed onto the corrugated material plate 22, and the first belt drive 27 operates to drive the corrugated material plate 22 to run in the conveyor 20. When the lead wire reaches the predetermined position, the second hydraulic push rod 18 operates to push the cutting blade 23 to position and cut the lead wire. The cut pencil lead enters the discharge hopper 15, and after a little sorting, the external controller turns on the second servo motor 37 to drive the connecting rod 60 to rotate a predetermined angle, so that the swing bridge 36 is driven to swing, and the pull rod 38 is driven to move during the swing, thereby driving the second vertical plate 35 to send out a certain amount of lead, and the first vertical plate 34 is intercepted again, so as to achieve the purpose of quantitative collection and packaging.
