DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Please refer to Figure 1 - Figure 5 The present application provides a technical solution: a compression roller mechanical limiting mechanism suitable for different anilox roller diameters, comprising a main body 100 and a limiting mechanism 200. The main body 100 comprises a pair of mounting frames 1001, and the two opposite faces of the pair of mounting frames 1001 are provided with anilox rollers 1002 at the bottom ends. The limiting mechanism 200 comprises a pair of fixed frames 2001, which are arranged on the inner side of one of the mounting frames 1001. One side of the pair of fixed frames 2001 is fixedly provided with a sliding shaft 2003. A sliding block 2004 is movably sleeved on the sliding shaft 2003. One side of the sliding block 2004 is fixedly provided with a limiting block 2005. One side of the sliding block 2004 is threadedly connected with a screw rod 2006. One end of the screw rod 2006 abuts against the outer side of the sliding shaft 2003. The other end of the screw rod 2006 is fixedly provided with a handle 2007 on the outer side. By arranging the sliding shaft 2003 on one side of the pair of fixed frames 2001 and movably sleeving the sliding block 2004 on the sliding shaft 2003, the sliding block 2004 can slide up and down and rotate on the sliding shaft 2003, so that the user can conveniently adjust the position of the limiting block 2005. By arranging the limiting block 2005 on one side of the sliding block 2004 and abutting the limiting block 2005 against the pressing plate 1006, the compression roller 1008 can be limited. By threadedly connecting the screw rod 2006 with one side of the sliding block 2004 and abutting one end of the screw rod 2006 against the outer side of the sliding shaft 2003, the user can conveniently fix the sliding block 2004 on the sliding shaft 2003, so as to adjust the position of the limiting block 2005, so as to be suitable for different production conditions. By arranging the handle 2007 on the outer side of one end of the screw rod 2006, the user can conveniently rotate the screw rod 2006, so as to fix the sliding block 2004.

[0029] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] See also Figure 1 - Figure 5 , a pair of mounting frames 1001 have connecting frames 1003 fixedly installed on their upper sides on two opposite surfaces, and a telescopic rod 1004 is installed on one end of the connecting frame 1003, and a joint bearing 1005 is sleeved on the bottom end of the telescopic rod 1004, and a sliding rail 1009 is fixedly installed on the two opposite surfaces of the pair of mounting frames 1001 at the bottom end of the connecting frame 1003, and a pressure plate 1006 is slidably installed on the slide rail 1009, and a limit block 2005 is located at the upper end of one of the pressure plates 1006, and a rotating shaft is installed on the upper end of the two opposite surfaces of the pressure plate 1006, and one end of the rotating shaft is sleeved on the inside of the joint bearing 1005, and a bearing seat 1007 is fixedly installed on the two opposite surfaces of the pressure plate 1006, and a pressure roller 1008 is sleeved between a pair of bearing seats 1007. A telescopic rod 1004 is installed at one end of the frame 1003, and a joint bearing 1005 is installed at its movable end to facilitate the pressure plate 1006 to move up and down. By installing a slide rail 1009 and sliding the pressure plate 1006 thereon, the pressure plate 1006 can move up and down under the action of the telescopic rod 1004, thereby driving the pressure roller 1008 to rise and fall. By setting a limit block 2005 on one side of the upper end of the pressure plate 1006, when the pressure plate 1006 rises to the bottom end of the limit block 2005, it will not be able to continue to rise. By connecting the joint bearing 1005 with the rotating shaft, the telescopic rod 1004 can drive the pressure plate 1006 to move up and down when working. By arranging a pressure roller 1008 between a pair of bearing seats 1007, the pressure roller 1008 can be rotated.

[0031] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1 - Figure 5A scale 2002 is fixedly installed between a pair of fixing frames 2001 on the side away from the sliding shaft 2003, a pointer 2008 is installed on the upper end of the slider 2004, and a rubber pad is provided on the end of the screw 2006 close to the sliding shaft 2003. By installing the scale 2002 and installing the pointer 2008 on the upper end of the slider 2004, it is convenient to observe the moving distance and position of the limit block 2005. By arranging a rubber pad at one end of the screw 2006, the friction between the end of the screw 2006 and the sliding shaft 2003 is increased, so that the screw 2006 can better fix the slider 2004 and the sliding shaft 2003 together.

[0033] Specifically, the working principle of the mechanical limiting mechanism of the pressure roller that adapts to different plate roller diameters is as follows: when in use, the user can select anilox rollers 1002 of different diameters according to production needs, and by starting the telescopic rod 1004, the joint bearing 1005 provided on the moving end of the pressure roller 1006, which is slidably connected to the slide rail 1009, is driven to move up and down. A bearing seat 1007 is installed on the bottom side of the pressure plate 1006, and a pressure roller 1008 is provided between the bearing seats 1007. The user can adjust the height of the pressure roller 1008 according to the diameter of the anilox roller 1002. Correspondingly, the user drives the screw 2006 to rotate by the handle 2007. One end of the screw 2006 is separated from the sliding shaft 2003, so that the slider 2004 can slide on the sliding shaft 2003. A pointer 2008 is installed on one side of the upper end of the slider 2004, and one end of the pointer 2008 points to the left. When the pressing plate 1006 needs to be raised to the highest position, the user can loosen the fixation of the slider 2004 and rotate it on the sliding shaft 2003 to a certain angle. The limit block 2005 installed on one side of the slider 2004 will change and no longer limit the pressing plate 1006, so that the pressing roller 1008 can be raised to the top along with the telescopic rod 1004.
