Description

Technical Field

[0001] The utility model relates to the technical field of pencil production, in particular to a new type of pencil board rod planing machine. Background Art

[0002] In the pencil manufacturing industry, the manufacturing of pencils mainly includes processes such as pencil boards, leads, pencil rods, finished product decoration, and packaging. First, pencil board processing: The log is sawn and cut into blocks, and then sawn into square blocks. After hydrothermal treatment, it is cut into pencil boards by a cutting machine. Second, lead processing: Graphite leads are prepared by mixing graphite and clay in a certain proportion. After being kneaded and mixed by a kneading machine and a three-roll machine, the leads of a certain specification size are extruded by a core pressing machine, and then heated, dried, and calcined at high temperature to make them have a certain mechanical strength and hardness, and are made after oil immersion treatment. After that, pencil rod processing: The pencil board is planed to the required thickness and has a core groove adapted to the diameter of the lead. Then, the lead and the pencil board are glued together with an adhesive, and after being heated and dried in a clamped state, they are processed by a rod planing machine to make a white rod pencil. After that, appearance decoration processing: The white rod pencil is painted, printed, cut, printed with trademarks, and fitted with erasers, etc., to make it a finished pencil with a certain specification, appearance color, and pattern. Finally, it is packaged and sold.

[0033] In this embodiment, to ensure the conveying effect of the lower material conveying roller 902 on the pencil board 17, it is necessary to adjust the overall height of the cross beam 16 through the lifting device 8, so that the lower material conveying roller 902 is rotatably arranged in the lower material conveying roller groove 903 and the highest point of the lower material conveying roller 902 is slightly higher than the top surface of the material conveying platform 4, so that it can contact the bottom surface of the pencil board 17. The output end of the lifting motor 801 drives the lifting main shaft 802 to rotate. The two active lifting turbines 803 on the lifting main shaft 802 rotate simultaneously, and drive the two lifting lead screws 805 to rotate synchronously through the passive lifting turbines 806 matched with them. The rotation of the lifting lead screw 805 drives the lifting support column 7 to rise or fall through the nut seat 804, realizing the adjustment of the overall height of the cross beam 16.

[0034] The material conveying driving device 10 includes a material conveying motor 1001 and a plurality of material conveying gearboxes 1003. The material conveying motor 1001 is fixedly arranged at the front end of the cross beam 16.

[0035] In this embodiment, the material conveying driving device 10 is used to drive a plurality of upper material conveying roller wheels 901 and a plurality of lower material conveying roller wheels 902 to rotate in opposite directions and at the same speed, and sequentially convey a plurality of pencil boards 17 to the planing rod platform 5. The output end of the material conveying motor 1001 drives the material conveying main shaft 1002 to rotate. The material conveying main shaft 1002 rotates and simultaneously drives the gears in a plurality of material conveying gearboxes 1003 to rotate. Through the meshing transmission of the gears in the material conveying gearbox 1003, the upper material conveying output shaft 1004 and the lower material conveying output shaft 1005 at the two output ends of the material conveying gearbox 1003 rotate in opposite directions and at the same speed, and drive the upper material conveying roller wheels 901 and the lower material conveying roller wheels 902 to rotate in opposite directions and at the same speed through the material conveying universal joint 1006. Preferably, using the material conveying universal joint 1006 can ensure that the rotation of the upper material conveying roller wheels 901 and the lower material conveying roller wheels 902 is not affected after height adjustment. The material conveying gearbox 1003 in this embodiment is a re-application of the prior art, and its specific structure will not be described in detail.

[0036] The upper material conveying roller wheel lifting device 11 includes an upper material conveying roller wheel sleeve 1101 and an upper material conveying roller wheel lifting cylinder 1102. The upper material conveying roller wheel sleeve 1101 is sleeved outside the upper material conveying roller wheel 901 and is rotatably connected thereto.

[0037] In this embodiment, the upper material conveying roller wheel lifting device 11 is used to adjust the height of the upper material conveying roller wheel 901 so that it is suitable for pencil boards 17 of different thicknesses, and ensure that the upper material conveying roller wheel 901 can contact the top surface of the pencil board 17. The output end of the upper material conveying roller wheel lifting cylinder 1102 contracts or extends, and drives the upper material conveying roller wheel 901 to move up or down along the cross beam 16 through the upper material conveying roller wheel sleeve 1101, realizing the adjustment of the distance between the upper material conveying roller wheel 901 and the top surface of the material conveying platform 4, making it suitable for pencil boards 17 of different thicknesses, and ensuring that the upper material conveying roller wheel 901 can contact the top surface of the pencil board 17.

[0038] The upper material conveying roller wheel buffer device 12 includes a buffer connecting plate 1201 and a plurality of buffer shock-absorbing rods 1203. A plurality of connecting holes 1202 are formed in the buffer connecting plate 1201. The upper material conveying roller wheel 901 is rotatably arranged in the connecting holes 1202.

[0039] In this embodiment, the feeding roller buffer device 12 plays a buffering role when the upper feeding roller 901 conveys the pencil board 17. The upper feeding roller 901 is in buffer elastic contact with the top surface of the pencil board 17 to ensure that the movement of the pencil board 17 is more stable. When the pencil board 17 enters between the top surfaces of the upper feeding roller 901 and the feeding platform 4 and moves backward, if the height of the upper feeding roller 901 is fixed, the top surface of the pencil board 17 will rub against or squeeze it, affecting the stability of the movement of the pencil board 17. When the top surface of the pencil board 17 rubs against or squeezes the upper feeding roller 901, the buffer shock-absorbing rod 1203 timely fine-tunes the height of the upper feeding roller 901 to reduce the influence of friction or extrusion on the movement stability of the pencil board 17, and cooperates with multiple upper feeding rollers 901 and multiple lower feeding rollers 902 to enable the pencil board 17 to move smoothly.

[0040] A guiding strip 18 is fixedly arranged on the top of the planing rod platform 5, and the guiding strip 18 cooperates with a guiding groove 20 arranged on the bottom surface of the pencil board 17.

[0041] In this embodiment, after the upper feeding roller 901 and the lower feeding roller 902 transfer the pencil board 17 to the planing rod platform 5, the subsequent pencil board 17 pushes the previous pencil board 17 to continue moving in sequence. The pencil board 17 is positioned through the guiding groove 20 and the guiding strip 18 in sliding fit to ensure the accuracy of the grooving position of the grooving device 13 above the planing rod platform 5 and ensure the quality of the product.

[0042] The pressing device 14 includes two pressing shafts 1401 fixedly connected to the planing rod platform 5. A pressing beam 1402 is arranged between the two pressing shafts 1401. The two ends of the pressing beam 1402 are respectively slidably connected to the two pressing shafts 1401. A pressing claw 1404 in contact and cooperation with the pencil board 17 is fixedly arranged on the pressing shaft 1401, and a pressing spring 1403 cooperating with the pressing beam 1402 is sleeved outside the pressing shaft 1401.

[0043] In this embodiment, the pencil board 17 moves backward along the top surface of the planing rod platform 5 under the cooperation of the guiding groove 20 and the guiding strip 18. The pencil board 17 squeezes the pressing claw 1404 to move upward, and the pressing spring 1403 contracts. The pencil board 17 enters below the pressing beam 1402, and the resilience of the pressing spring 1403 enables the pressing claw 1404 to tightly press the top surface of the pencil board 17 while the pencil board 17 moves backward, preventing the pencil board 17 from jumping when the grooving device 13 grooves the pencil board 17 and affecting the quality of the product.

[0044] The grooving device 13 includes a grooving motor 1301 and a grooving main shaft 1303. The grooving main shaft 1303 is rotatably arranged below the cross beam 16. The grooving motor 1301 is fixedly arranged below the cross beam 16. A grooving driving pulley 1302 is fixedly arranged at the output end of the grooving motor 1301. A grooving driven pulley 1304 is fixedly arranged at one end of the grooving main shaft 1303. The grooving driving pulley 1302 and the grooving driven pulley 1304 are drivingly connected by a grooving belt 1305. A grooving tool is detachably arranged at the other end of the grooving main shaft 1303.

[0045] In this embodiment, the output end of the grooving motor 1301 drives the grooving main shaft 1303 to rotate through the grooving driving pulley 1302, the grooving belt 1305 and the grooving driven pulley 1304. The grooving tool mounted on the grooving main shaft 1303 grooves the top surface of the pencil board 17.

[0046] An upper cover plate 15 is fixedly arranged above the rear part of the planing bar platform 5. The upper cover plate 15 is fixedly connected to the top surface of the planing bar platform 5. An upper grooving slideway 1501 is formed in the upper cover plate 15. A lower grooving hole 19 is formed in the planing bar platform 5 below the upper cover plate 15.

[0047] In this embodiment, the pencil board 17 after grooving the top surface continues to move forward and backward and enters the upper cover plate 15. The upper grooving slideway 1501 arranged in the upper cover plate 15 cooperates with the grooving on the top surface of the pencil board 17 and continues to position the upper cover plate 15 to ensure the accuracy of the grooving position of the grooving device 13 below the planing bar platform 5 and ensure the quality of the product. The pressing claws 1404 of the pressing device 14 below the planing bar platform 5 pass through the lower grooving hole 19 and press the bottom surface of the pencil board 17 while the pencil board 17 moves backward to prevent the pencil board 17 from jumping when the grooving device 13 grooves the pencil board 17, which affects the quality of the product. The grooving tool on the grooving main shaft 1303 below the planing bar platform 5 grooves the bottom surface of the pencil board 17. The grooving on the top surface of the pencil board 17 and the grooving on the bottom surface of the pencil board 17 cooperate to realize the planing processing of the pencil rod.
