[0002] Paper tube finishing machines are generally used to process the cut ends of paper tubes after cutting, including polishing the cut position to make the cut smoother; or installing accessories at the cut position to meet specific usage requirements.

[0003] In the process of grinding the paper tube cutout by the finishing machine, in order to achieve a high standard of processing effect, it is generally necessary to complete multiple processing processes from coarse sanding to fine sanding to polishing in sequence. However, since most finishing machines can only use a single specification of grinding disc for grinding at a time, a complete grinding process requires switching multiple grinding discs of different specifications.

The outer walls of the same side of the support block 205 are respectively fitted with grinding sheets 206, and the multiple grinding sheets 206 can be grouped according to the grouping of the triangular support blocks 205, and the mesh number of each group of grinding sheets 206 can be set from small to large or from large to small. The outer wall of the other side of each triangular support block 205 is respectively fixedly connected with a protruding rod 209 and a supporting rod 217, and a supporting plate 216 is fixedly arranged on the supporting rod 217; a first annular slide groove is arranged in the first support shell 203, and an annular guide plate 219 is movably connected in the first annular slide groove through a first clamping ring 201, and a plurality of guiding protrusions 218 are arranged on the outer wall of one side of the annular guide plate 219, and each guiding protrusion 218 corresponds to the multiple triangular support blocks 205 and the protruding rod 209 of the same group, and the outer wall of the annular guide plate 219 is fixedly connected with an outer gear ring 202, and the outer gear ring 202 is meshed with a gear 212, and a stepping motor 213 is fixedly connected to one side of the gear 212;The inner wall of the first support shell 203 is fixedly connected with a support shaft 204, one end of which is connected with a rotation driving mechanism 6, and is driven to rotate under the action of the rotation driving mechanism 6, the middle section of the support shaft 204 is fixedly connected with a first limiting circular plate 210, and a plurality of support rods 217 pass through the first limiting circular plate 210, and a spring 211 is arranged between each support plate 216 and the first limiting circular plate 210, and the grinding mechanism 2 is used to grind the two ends of the paper tube during the finishing process of the paper tube, wherein the plurality of triangular support blocks 205 are divided into a plurality of groups, and each group of triangular support blocks 205 is covered with grinding sheets 206 of different specifications, when the stepping motor 213 drives the gear When the wheel 212 and the outer gear ring 202 rotate, the highest point positions of the multiple guide protrusions 218 on the annular guide plate 219 are changed so that they contact the protrusions 209 on different groups of triangular support blocks 205, thereby propping up the triangular support blocks 205 of the same group, so that they are located outside the triangular support blocks 205 of other groups and contact the end surface of the paper tube. As the rotating drive mechanism 6 drives the entire first support shell 203 to rotate, the grinding sheets 206 of the same group are sequentially contacted with the ports of the paper tube, so that multiple processing processes from coarse sand to fine sand to polishing can be completed sequentially, thereby avoiding the switching process of different grinding sheets 206, and playing a role in optimizing the grinding efficiency. ;

[0026] Reference Figure 2 In a preferred embodiment, one end of the support shaft 204 is attached to the inner side of the plurality of triangular support blocks 205 , a second limiting circular plate 215 is fixedly connected to the first support shell 203 , and a plurality of protruding rods 209 are movably inserted into the second limiting circular plate 215 .

[0027] Reference Figure 7 and Figure 8 In a preferred embodiment, the grinding sheet cleaning mechanism 10 includes a through hole 1001, and a rubber block 1005 is movably inserted in the through hole 1001, a groove is provided on one side of the rubber block 1005, and a high-density foam block 1009 is embedded in the groove, and the same end of the high-density foam block 1009 and the rubber block 1005 is connected to a top plate 1007 at the same time.

[0028] Reference Figure 7 and Figure 8 In a preferred embodiment, a plurality of small bumps 1008 are provided at the contact position between the top plate 1007 and the high-density foam block 1009, a jacket 1004 is sleeved on the outer side of the top plate 1007, and a hydraulic rod 1003 is fixedly connected to one side of the jacket 1004, and the hydraulic rod 1003 is fixed to one side of the second support shell 207 through the first bracket 1002.

[0029] Reference Figure 7 and Figure 8In a preferred embodiment, the light source 1006 is fixedly connected to the inner wall of one side of the second supporting shell 207, and the second bracket 1011 is fixedly connected to the inner wall of the same side of the second supporting shell 207, and one end of the second bracket 1011 is fixedly connected to the mounting bracket 1012.

[0030] Reference Figure 7 and Figure 8 In a preferred embodiment, a brightness sensor 1013 is installed on the inner wall of the mounting frame 1012, and an electric heating plate 1010 is installed on the inner wall of the top of the mounting frame 1012. The electric heating plate 1010 is in contact with the high-density foam block 1009. The grinding sheet cleaning mechanism 10 mainly cleans the surfaces of multiple grinding sheets 206 of different specifications, so that the paper scraps adhering to the grinding sheet 206 during the grinding process are separated, and the service life of the grinding sheet 206 is extended while ensuring the grinding effect of the grinding sheet 206. The rubber block 1005 can take away the paper scraps on the grinding sheet 206, but the rubber block 1005 will also cause wear during the cleaning process, and the contact position between the rubber block 1005 and the grinding sheet 206 also has certain requirements. It cannot be squeezed too much, and the contact with the grinding sheet 206 must be guaranteed. The high-density foam block 1009 can play a role in supporting the rubber block 1005 to avoid the loss of a piece of shadow The rubber block 1005 and the grinding sheet 206 are squeezed, and the electric heating plate 1010 is in contact with the high-density foam block 1009, which can drive the high-density foam block 1009 to melt. If the rubber block 1005 just fits on the grinding sheet 206, the brightness sensor 1013 is completely blocked. If loss occurs during the cleaning process, the light source 1006 will be received by the brightness sensor 1013 at the loss point, thereby driving the hydraulic rod 1003 to drive the rubber block 1005 to move a micro distance to complete the loading of the rubber block 1005. Therefore, the squeezing degree between the grinding sheet 206 and the rubber block 1005 can be adjusted. While achieving the optimal cleaning effect, excessive loss of the rubber block 1005 is avoided. At the same time, under the action of multiple small bumps 1008, the waste generated by the melting of the high-density foam block 1009 can be prevented from remaining on the electric heating plate 1010.

[0031] Reference Figure 6 In a preferred embodiment, the paper tube cleaning mechanism 9 includes a through groove 901, and the through groove 901 is fixed to one side of the second supporting shell 207, the paper tube enters the second supporting shell 207 through the through groove 901, and the inner diameter of the through groove 901 is greater than the outer diameter of the paper tube.

[0032] Reference Figure 6 In a preferred embodiment, the inner wall of the groove 901 is tightly connected with multiple exhaust pipes 902, and the exhaust pipes 902 are used to connect to an external vacuum pump, one end of the groove 901 is fixedly connected with an elastic tube 903, and one end of the elastic tube 903 is fixedly connected with a rubber sleeve 904.

[0033] Reference Figure 6 In a preferred embodiment, the rubber sleeve 904 is tightly sleeved on the outer wall of the paper tube, a card interface 905 is provided between the through groove 901 and the elastic tube 903, and the card interface 905 is fitted to the outer wall of the paper tube, the other end of the through groove 901 is fixedly connected to a telescopic cover 907, and one end of the telescopic cover 907 is fixedly connected to an elastic belt 906. In the paper tube cleaning mechanism 9, when the two rotating drive mechanisms 6 move toward the two ends of the paper tube under the action of the guide rail 4, the two ends of the paper tube enter the second support shell 207 from the position of the rubber sleeve 904, and the elastic belt 906 is stretched open, so that the telescopic cover 907 covers the outside of the paper tube, and then the finishing and polishing are performed. After the grinding is completed, as the paper tube and the elastic band 906 are separated, the elastic band 906 retracts, driving the telescopic cover 907 to cover one side of the groove 901. At the same time, based on the fitting state of the card interface 905, a relatively sealed space is formed, so that the vacuum pipe 902 forms a negative pressure under the action of the external vacuum fan, and takes away the paper scraps adhered to the paper tube, thereby preventing the paper scraps from entering the paper tube and ensuring the neatness of the paper tube after finishing. In addition, under the action of the elastic tube 903 and the rubber sleeve 904, the connection length between the paper tube cleaning mechanism 9 and the paper tube during the movement is extended, thereby extending the maintenance time of the negative pressure space to ensure the paper scrap cleaning effect.

[0034] Working principle: The grinding mechanism 2 is used to grind the two ends of the paper tube during the finishing process of the paper tube, wherein the plurality of triangular support blocks 205 are divided into a plurality of groups, and each group of triangular support blocks 205 is covered with grinding sheets 206 of different specifications. When the stepping motor 213 drives the gear 212 and the outer gear ring 202 to rotate, the highest point position of the plurality of guide protrusions 218 on the annular guide plate 219 is changed so that they are respectively in contact with the protrusions 209 on the triangular support blocks 205 of different groups, thereby propping up the triangular support blocks 205 of the same group, so that they are located outside the triangular support blocks 205 of other groups, and contact with the end surface of the paper tube. As the rotating drive mechanism 6 drives the entire first support shell 203 to rotate, the grinding sheets 206 of the same group are sequentially contacted with the ports of the paper tube, so that multiple processing processes from coarse sand to fine sand to polishing can be completed sequentially, thereby avoiding the switching process of different grinding sheets 206, and playing a role in optimizing the grinding efficiency. In addition, the grinding sheet cleaning mechanism 10 mainly cleans the surfaces of multiple grinding sheets 206 of different specifications, so that the paper scraps adhered to the grinding sheets 206 during the grinding process are separated, extending the service life of the grinding sheets 206 while ensuring the grinding effect of the grinding sheets 206. The rubber block 1005 can take away the grinding The rubber block 1005 can also be worn during the cleaning process, and the contact position between the rubber block 1005 and the polishing sheet 206 must be certain, so it cannot be squeezed too much, and it must be in contact with the polishing sheet 206. The high-density foam block 1009 can support the rubber block 1005 to avoid the missing piece affecting the squeezing effect of the rubber block 1005 and the polishing sheet 206. At the same time, the electric heating plate 1010 is in contact with the high-density foam block 1009 to drive the high-density foam block 1009 to melt. If the rubber block 1005 just fits on the polishing sheet 206, the brightness sensor 1013 causes complete obstruction. If loss occurs during the cleaning process, the light of the light source 1006 will be received by the brightness sensor 1013 at the loss point, thereby driving the hydraulic rod 1003 to drive the rubber block 1005 to move a micro distance, completing the loading of the rubber block 1005. Therefore, the squeezing degree between the grinding sheet 206 and the rubber block 1005 can be adjusted. While achieving the optimal cleaning effect, excessive loss of the rubber block 1005 is avoided. At the same time, under the action of multiple small protrusions 1008, the waste generated by melting the high-density foam block 1009 can be prevented from remaining on the electric heating plate 1010.
