Description

Technical Field

[0001] This invention relates to the field of pencil manufacturing technology, specifically a novel pencil board planer. Background Technology

[0002] In the pencil manufacturing industry, the production of pencils is mainly divided into processes such as pencil board, lead core, pencil shaft, finished product decoration, and packaging. First, pencil board processing: logs are split, cut, and sawn into blocks. After hydrothermal treatment, they are cut into pencil boards using a board cutting machine. Second, lead processing: graphite lead is made by mixing graphite and clay in a certain proportion, blending them in a kneading machine and a three-roll mill, and then extruding them into lead of a certain size using a core pressing machine. After heating, drying, and high-temperature firing, it gains a certain mechanical strength and hardness, and is then treated with oil. Next, pencil shaft processing: the pencil board is planed into a grooved board of the required thickness with a groove that matches the diameter of the lead. Then, the lead and pencil board are glued together with adhesive, heated and dried under clamping conditions, and then processed into white pencil shafts using a shaft planer. After that, the white pencil shafts are painted and printed, as well as finished, with labels printed and erasers attached, to become finished pencils with a certain size, appearance, color, and pattern. Finally, they are packaged and sold.

[0003] Commonly used pencils typically have round or hexagonal barrels. Current technology for planing pencil barrels usually involves single-barrel, single-sided planing, which is not only cumbersome and complex to operate, but also inefficient. Furthermore, inaccurate positioning of the planer leads to inconsistent quality, affecting the product's pass rate.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described as follows:

[0028] A novel pencil board planer includes a feeding platform 1, a fixed frame 3, a transfer platform 4, and a planer platform 5. A feeding device 2 is mounted on the feeding platform 1. Fixed seats 6 are located below both the transfer platform 4 and the planer platform 5. Lifting supports 7 are mounted above the two fixed seats 6 via a lifting device 8. The tops of the two lifting supports 7 are fixedly connected by a crossbeam 16. A transfer device 9, cooperating with the transfer platform 4, is located at the front of the crossbeam 16. The transfer device 9 includes multiple feed rollers 901 movably mounted above the transfer platform 4 and lower transfer rollers 902 rotatably mounted below the transfer platform 4 and cooperating with the feed rollers 901. The feed rollers 901 and lower transfer rollers... A lower transfer roller groove 903 is provided on the transfer platform 4 between the wheels 902. The lower transfer roller 902 is rotatably disposed in the lower transfer roller groove 903. A transfer drive device 10 is provided on the crossbeam 16 to drive the upper transfer roller 901 and the lower transfer roller 902 to rotate. The crossbeam 16 is also provided with an upper transfer roller lifting device 11 and an upper transfer roller buffer device 12 that cooperate with the multiple upper transfer rollers 901. A grooving device 13 is provided above the front part of the planer platform 5 and below the rear part of the planer platform 5. A pressing device 14 is provided on both the front and rear sides of the grooving device 13 to cooperate with it. The two grooving devices 13 respectively perform grooving processing on the top and bottom surfaces of the pencil board 17.

[0029] In this embodiment, the feeding device 2 is used to transport the pencil board 17 from the feeding platform 1 to the transfer platform 4. The transfer drive device 10 is used to drive multiple upper transfer rollers 901 and multiple lower transfer rollers 902 to rotate in opposite directions and at the same speed, so as to transport multiple pencil boards 17 sequentially to the planer platform 5. The lifting device 8 is used to lift the crossbeam 16 as a whole, and adjust the height of the lower transfer rollers 902 so that the lower transfer rollers 902 are rotatably set in the lower transfer roller groove 903 and the highest point of the lower transfer rollers 902 is slightly higher than the top surface of the transfer platform 4, so that they can contact the bottom surface of the pencil board 17. The upper transfer roller lifting device 11 is used to adjust the height of the upper transfer rollers 901 so that they can be used for pencil boards 17 of different thicknesses, and ensure that the upper transfer rollers 901 can contact the top surface of the pencil board 17. The feed roller buffer device 12 acts as a buffer when the feed roller 901 conveys the pencil board 17. The feed roller 901 and the top surface of the pencil board 17 make buffered elastic contact, ensuring smoother movement of the pencil board 17. Subsequent pencil boards 17 push the preceding pencil board 17, and the pencil board 17 enters the pressing device 14 above the front of the planer platform 5 for pressing and continues to move. The grooving blade installed on the grooving device 13 above the front of the planer platform 5 grooves the top surface of the pencil board 17. After the top surface of the pencil board 17 is processed, it continues to move to the pressing device 14 below the rear of the planer platform 5 for pressing and continues to move. The grooving blade installed on the grooving device 13 below the rear of the planer platform 5 grooves the bottom surface of the pencil board 17. Preferably, the grooving blade has multiple grooving teeth with equal spacing. After the two grooving blades respectively create grooves on the top and bottom surfaces of the pencil board 17, they combine to form the complete outer contour of the pencil barrel.

[0030] The feeding device 2 includes a feeding trough 201 and a feeding motor 202. The feeding trough 201 is provided in the middle of the feeding platform 1. The feeding motor 202 and the feeding gearbox 203 are fixedly installed below the feeding platform 1. The output end of the feeding gearbox 203 is fixedly installed with a feeding spindle 204. Two feeding drive sprockets 205 are fixedly installed on the feeding spindle 204. A feeding driven shaft 206 is also rotatably installed below the feeding platform 1. Two feeding driven sprockets 207 are fixedly installed on the feeding driven shaft 206. A feeding chain 208 is provided between the feeding drive sprockets 205 and the feeding driven sprockets 207. Multiple feeding paddles 209 are provided between the two feeding chains 208. The feeding paddles 209 slide in cooperation with the feeding trough 201.

[0031] In this embodiment, the feeding motor 202 drives the feeding drive sprocket 205, the feeding chain 208 and the feeding driven sprocket 207 to rotate. The feeding pusher block 209 rotates with the feeding chain 208 and then enters the feeding trough 201. The feeding pusher block 209 pushes the pencil board 17 on the feeding platform 1 to move backward to the transfer platform 4.

[0032] The lifting device 8 includes a lifting motor 801 and a lifting main shaft 802 fixedly connected to the output end of the lifting motor 801. The lifting motor 801 is fixed on the outside of one of the fixed seats 6. The two ends of the lifting main shaft 802 are rotatably connected to the tops of the two fixed seats 6 respectively. A screw nut seat 804 is fixedly provided at the bottom of the lifting support column 7. A lifting screw 805 that cooperates with the screw nut seat 804 is rotatably provided inside the screw nut seat 804. A passive lifting turbine 806 is fixedly provided at the bottom of the lifting screw 805. An active lifting turbine 803 that cooperates with the passive lifting turbine 806 is fixedly provided on the lifting main shaft 802.

[0033] In this embodiment, to ensure the conveying effect of the lower conveyor roller 902 on the pencil board 17, the overall height of the crossbeam 16 needs to be adjusted by the lifting device 8 so that the lower conveyor roller 902 is rotatably positioned within the lower conveyor roller groove 903, and the highest point of the lower conveyor roller 902 is slightly higher than the top surface of the conveying platform 4, allowing it to 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 through the passive lifting turbine 806 that cooperates with them, drive the two lifting screws 805 to rotate synchronously. The rotation of the lifting screws 805 drives the lifting support column 7 to rise or fall through the screw nut seat 804, thereby adjusting the overall height of the crossbeam 16.

[0034] The material transfer drive device 10 includes a material transfer motor 1001 and multiple material transfer gearboxes 1003. The material transfer motor 1001 is fixedly installed at the front end of the crossbeam 16, and multiple material transfer gearboxes 1003 are fixedly installed on the outer side of the crossbeam 16. A material transfer main shaft 1002 is fixedly installed at the output end of the material transfer motor 1001. The material transfer main shaft 1002 passes through multiple material transfer gearboxes 1003 in sequence and is driven and cooperates with their input ends. The material transfer gearbox 1003 is a dual-shaft output gearbox. The two output ends of the material transfer gearbox 1003 are respectively rotatably equipped with an upper material transfer output shaft 1004 and a lower material transfer output shaft 1005. The upper material transfer output shaft 1004 and the lower material transfer output shaft 1005 are rotatably connected to the upper material transfer roller 901 and the lower material transfer roller 902 through a material transfer universal joint 1006.

[0035] In this embodiment, the material transfer drive device 10 drives multiple feed rollers 901 and multiple feed rollers 902 to rotate in opposite directions and at the same speed, sequentially conveying multiple pencil boards 17 onto the planer platform 5. The output end of the material transfer motor 1001 drives the material transfer spindle 1002 to rotate. The rotation of the material transfer spindle 1002 simultaneously drives the gears in multiple material transfer gearboxes 1003 to rotate. Through the meshing transmission of the gears in the material transfer gearboxes 1003, the feed output shaft 1004 and the feed output shaft 1005 at the two output ends of the material transfer gearboxes 1003 rotate in opposite directions and at the same speed, and drive the feed rollers 901 and the feed rollers 902 to rotate in opposite directions and at the same speed through the material transfer universal joint 1006. Preferably, the use of the material transfer universal joint 1006 ensures that the rotation of the feed rollers 901 and the feed rollers 902 is not affected after height adjustment. The material transfer gearbox 1003 in this embodiment is a reapplication of existing technology, and its specific structure will not be described in detail.

[0036] The feeding roller lifting device 11 includes a feeding roller sleeve 1101 and a feeding roller lifting cylinder 1102. The feeding roller sleeve 1101 is sleeved on the outside of the feeding roller 901 and rotatably connected to it. The fixed end of the feeding roller lifting cylinder 1102 is fixedly connected to the crossbeam 16, and the output end of the feeding roller lifting cylinder 1102 is rotatably connected to the feeding roller sleeve 1101.

[0037] In this embodiment, the feeding roller lifting device 11 is used to adjust the height of the feeding roller 901 to make it suitable for pencil boards 17 of different thicknesses, ensuring that the feeding roller 901 can contact the top surface of the pencil board 17. The output end of the feeding roller lifting cylinder 1102 retracts or extends, and drives the feeding roller 901 to move up or down along the crossbeam 16 through the feeding roller sleeve 1101, thereby adjusting the distance between the feeding roller 901 and the top surface of the feeding platform 4 to make it suitable for pencil boards 17 of different thicknesses, ensuring that the feeding roller 901 can contact the top surface of the pencil board 17.

[0038] The feeding roller buffer device 12 includes a buffer connecting plate 1201 and multiple buffer damping rods 1203. Multiple connecting holes 1202 are provided on the buffer connecting plate 1201. The feeding roller 901 is rotatably disposed in the connecting holes 1202. One end of the buffer damping rod 1203 is rotatably connected to the crossbeam 16, and the other end of the buffer damping rod 1203 is rotatably connected to the buffer connecting plate 1201.

[0039] In this embodiment, the feed roller buffer device 12 acts as a buffer when the feed roller 901 conveys the pencil board 17. The feed roller 901 and the top surface of the pencil board 17 make buffered elastic contact, ensuring smoother movement of the pencil board 17. When the pencil board 17 enters between the feed roller 901 and the top surface of the feed platform 4 and moves backward, if the height of the feed roller 901 is fixed, the top surface of the pencil board 17 will rub or be squeezed against it, affecting the stability of the pencil board 17's movement. When the top surface of the pencil board 17 rubs or is squeezed against the feed roller 901, the buffer damping rod 1203 promptly fine-tunes the height of the feed roller 901 to reduce the impact of friction or squeezing on the stability of the pencil board 17's movement. It also works in conjunction with multiple feed rollers 901 and multiple lower feed rollers 902 to ensure smooth movement of the pencil board 17.

[0040] A guide bar 18 is fixedly installed on the top of the planer platform 5, and the guide bar 18 cooperates with the guide groove 20 set on the bottom surface of the pencil board 17.

[0041] In this embodiment, after the upper feed roller 901 and lower feed roller 902 transfer the pencil board 17 to the planer platform 5, the subsequent pencil board 17 pushes the preceding pencil board 17 to continue moving. The pencil board 17 is positioned by the slidingly fitted guide groove 20 and guide bar 18 to ensure the accuracy of the grooving position of the grooving device 13 above the planer platform 5 and to ensure the quality of the product.

[0042] The pressing device 14 includes two pressing shafts 1401 fixedly connected to the planer platform 5. A pressing beam 1402 is provided between the two pressing shafts 1401. The two ends of the pressing beam 1402 are slidably connected to the two pressing shafts 1401 respectively. A pressing claw 1404 that contacts and cooperates with the pencil board 17 is fixedly provided on the pressing shaft 1401. A pressing spring 1403 that cooperates with the pressing beam 1402 is sleeved on the outside of the pressing shaft 1401.

[0043] In this embodiment, the pencil plate 17 moves backward along the top surface of the planer platform 5 with the cooperation of the guide groove 20 and the guide strip 18. The pencil plate 17 presses the pressing claw 1404 upward, the pressing spring 1403 retracts, and the pencil plate 17 enters below the pressing beam 1402. The rebound force of the pressing spring 1403 causes the pressing claw 1404 to press the top surface of the pencil plate 17 while the pencil plate 17 moves backward, preventing the pencil plate 17 from jumping when the grooving device 13 grooves the pencil plate 17, which would affect the quality of the product.

[0044] The grooving device 13 includes a grooving motor 1301 and a grooving spindle 1303. The grooving spindle 1303 is rotatably mounted below the crossbeam 16, and the grooving motor 1301 is fixedly mounted below the crossbeam 16. A grooving drive pulley 1302 is fixedly mounted at the output end of the grooving motor 1301, and a grooving driven pulley 1304 is fixedly mounted at one end of the grooving spindle 1303. The grooving drive pulley 1302 and the grooving driven pulley 1304 are connected by a planing strip belt 1305. A grooving cutter is detachably mounted at the other end of the grooving spindle 1303.

[0045] In this embodiment, the output end of the grooving motor 1301 drives the grooving spindle 1303 to rotate through the grooving drive pulley 1302, the grooving strip belt 1305 and the grooving passive pulley 1304, and the grooving cutter installed on the grooving spindle 1303 grooves the top surface of the pencil board 17.

[0046] A top cover plate 15 is fixedly installed on the upper rear part of the planer platform 5. The top cover plate 15 is fixedly connected to the top surface of the planer platform 5. An upper planing groove slide 1501 is opened in the top cover plate 15, and a lower planing groove hole 19 is opened on the planer platform 5 below the top cover plate 15.

[0047] In this embodiment, the pencil board 17, after being grooved on its top surface, continues to move and enters the upper cover plate 15. The upper grooving slide 1501 provided 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, ensuring the accuracy of the grooving position of the grooving device 13 below the planer platform 5 and ensuring product quality. The pressure claw 1404 of the pressure device 14 below the planer platform 5 passes through the lower grooving hole 19 and presses the bottom 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, which would affect product quality. The grooving cutter on the grooving spindle 1303 below the planer 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 barrel.
