DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a printing device for producing a nursing pad, comprising: a workbench 1, wherein support legs are fixed at the four corner positions of the bottom end of the workbench 1; a tensioning roller 1 4, a tensioning roller 2 5, and a tensioning roller 3 6, wherein the tensioning roller 1 4, the tensioning roller 2 5, and the tensioning roller 3 6 are all arranged on the top of the workbench 1, and the tensioning roller 1 4, the tensioning roller 2 5, and the tensioning roller 3 6 are arranged from left to right on the top of the workbench 1, and the tensioning roller 1 4, the tensioning roller 2 5, and the tensioning roller 3 6 are used to tension the nursing pad;

[0022] The dust collection component 3 is arranged on the top of the tensioning roller 2 5, and the dust collection component 3 is used for dust absorption; the dust collection component 3 includes a dust collection hood 31 fixed on the top of the tensioning roller 2 5, a shell 34 fixed on the workbench 1, a collection drawer 35 sliding in the shell 34, a pipe 32 connected between the dust collection hood 31 and the shell 34, and a negative pressure fan 33 installed on the shell 34. The input end of the negative pressure fan 33 is connected to the pipe 32, and the output end of the negative pressure fan 33 is connected to the shell 34. Start the negative pressure fan 33, and the operation of the negative pressure fan 33 forms a negative pressure in the dust hood 31. When the dust hood 31 forms a negative pressure, the impurities or debris remaining on the surface of the nursing pad wound around the tensioning roller 2 5 are cleaned, and the adsorbed impurities and debris fall into the collecting drawer 35, and the debris is collected by the collecting drawer 35. Since a handle is fixed on the collecting drawer 35, the collecting drawer 35 can be taken out of the shell 34 by holding the handle tightly, thereby cleaning the debris in the collecting drawer 35.

[0023] See also Figure 2 -3, printing component 2, the printing component 2 is arranged on one side of the top of the workbench 1, and the printing component 2 is used for printing processing; the printing component 2 includes a bracket 21 fixed at both ends of one side of the top of the workbench 1, an extrusion roller 22 rotating between the brackets 21 and close to the bottom, a through hole 24 opened in the bracket 21, a U-shaped frame 25 inserted between the brackets 21 through the through hole 24, a printing roller 23 rotating inside the U-shaped frame 25, and a second servo motor 26 installed on one side of the bracket 21; a lifting component 7, the lifting component 7 is arranged at the top of the printing component 2, and the lifting component 7 is used to lift the printing component 2 and adjust it reasonably according to the thickness of the nursing pad; the lifting component 7 includes a screw 72 rotating inside the through hole 24, a servo motor 71 installed on the top of the bracket 21 and driving the screw 72 to rotate, and a thread passes through the screw 72 and the U-shaped frame 25. Servo motor 71 is activated, and its output shaft drives screw 72 to rotate. Since screw 72 and U-shaped frame 25 are threadedly connected, through-hole 24 guides U-shaped frame 25. Therefore, as screw 72 rotates, it drives U-shaped frame 25 up and down. This up and down movement of U-shaped frame 25 adjusts the distance between squeezing roller 22 and printing roller 23, allowing printing on nursing pads of varying thicknesses.

[0024] See also Figure 3 -4. Transmission assembly 8. This assembly is mounted on one side of the printing assembly 2 and is used to rotate the printing assembly 2. It comprises a transmission wheel 81 secured to the output of the second servo motor 26 and the ends of the printing roller 23, and a belt 82 that fits over the two transmission wheels 81. When the second servo motor 26 is activated, the output shaft of the second servo motor 26 rotates the transmission wheel 81, which in turn, in conjunction with the belt 82, rotates the printing roller 23, achieving the twist-feed printing process on the nursing pad.

[0025] See also Figure 1-4. The tensioning assembly 9 includes a gear 91 fixed to the bottom of the screw 72, a rack 92 disposed outside the bracket 21 and meshing with the gear 91, and a contact rod 95 fixed to the side of the rack 92 away from the bracket 21. The contact rod 95 contacts the belt 82. The tensioning assembly 9 also includes a fixing plate 94 fixed to the outer wall of the bracket 21, a guide slot 96 defined at the top of the fixing plate 94, and a slider 93 fixed to the bottom of the rack 92. The slider 93 slides on the fixing plate 94 through the guide slot 96. However, as the screw 72 rotates, the screw 72 drives the gear 91 to rotate simultaneously. The rotation of the gear 91 actuates the movement of the rack 92. The rack 92, in cooperation with the slider 93, moves smoothly along the guide slot 96 above the fixing plate 94. As the rack 92 moves, the contact rod 95 adjusts the tension on the belt 82. Therefore, the belt 82 is smoothly tensioned while the U-shaped frame 25 moves up and down.

[0026] Working principle: First, the uncut and long nursing pad is wound around the tensioning roller three 6, the tensioning roller two 5 and the tensioning roller one 4, and passes through the squeezing roller 22 and the printing roller 23, and the servo motor one 71 is started. The output shaft of the servo motor one 71 drives the screw 72 to rotate, and the U-shaped frame 25 is driven up and down by the rotation of the screw 72. At this time, the squeezing roller 22 and the printing roller 23 squeeze the nursing pad, and then the second servo motor 26 is started. The output shaft of the second servo motor 26 drives the squeezing roller 22 to rotate, and in the process of the squeezing roller 22 rotating, the printing roller 23 and the squeezing roller 22 rotate simultaneously through the transmission wheel 81 and the belt 82, so that the nursing pad can be printed.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
