Description

Technical Field

[0002] A printing press is a machine for printing text and images. A modern printing press is generally composed of mechanisms such as plate loading, inking, embossing, and paper feeding (including folding). Its working principle is: first, the text and image to be printed are made into a printing plate and mounted on a printing press. Then, ink is applied to the places with text and images on the printing plate by hand or by a printing press, and then directly or indirectly transferred to paper or other substrates (such as textiles, metal plates, plastics, leather, wood boards, glass and ceramics), thereby replicating printed products identical to the printing plate. The invention and development of the printing press has played an important role in the spread of human civilization and culture.

The number of rollers 5 is set to four, and each two rollers 5 symmetrically distributed up and down form a group. One end of each group of rollers 5 is meshed and connected through two spur gears 6 for transmission. A pulley 8 and a belt 9 are set between the two groups of rollers 5 for transmission, so that the two groups of rollers 5 rotate in the same direction. Through the setting of the two groups of rollers 5, not only the efficiency of printing coil transportation is high, but also the printing coil can be flattened to avoid the curling of the printing coil, thereby ensuring the quality pass rate of the finished printing coil after printing.

[0031] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, it is worth specifically explaining that the tension adjustment assembly 7 includes two brackets 71, the two brackets 71 are symmetrically distributed and fixed to the top side wall of the bottom substrate 1, and the adjacent side walls of the two brackets 71 are each provided with a through groove 72, and a slider 73 is slidably connected inside the through groove 72, and the adjacent side walls of the two sliders 73 are rotatably connected to a sliding roller 74; two rotating seats 75, the two rotating seats 75 are symmetrically distributed and fixed to the side wall of one side of one of the brackets 71, and the adjacent side walls of the two rotating seats 75 are rotatably connected to a threaded rod 76, and a threaded sleeve 77 is threadedly connected to the external thread of the threaded rod 76, and one side of the threaded sleeve 77 The side wall is fixed to the side wall of one of the sliders 73, a support plate 78 is fixed to the side wall of one of the brackets 71, a servo motor 79 is fixed to the side wall of one side of the support plate 78, one end of the output shaft of the servo motor 79 is coaxially fixed to one end of the threaded rod 76, and the tensioning adjustment component 7 can be used to adjust the tensioning degree of the printed coil during transportation in real time to avoid curling or even disorder of the printed coil due to insufficient tensioning force during transportation, and to improve the overall printing quality of the final printed coil to a certain extent.

Through the shape setting of the slider 73, not only can the slider 73 be moved in a relatively stable state in the slide groove, but also the displacement caused by the movement of the slider 73 can be avoided.

[0033] This scheme has the following working process: when the printing coil used for printing on the printing press needs to be conveyed, the coil is conveyed from the guide roller 3 to the bottom of the sliding roller 74 and to the position between the multiple roller shafts 5, and the driving motor 11 drives one roller shaft 5 to rotate synchronously, and the meshing transmission effect between the two spur gears 6 is used to realize the steering of the two roller shafts 5 located above and below to run in opposite directions, and the transmission effect of the pulley 8 and the belt 9 is used to achieve the steering of the two groups of roller shafts 5 to rotate in the same direction, and the coil needs to be conveyed. The tension of the coil needs to be adjusted. When force is applied, the threaded rod 76 is driven by the servo motor 79 to rotate synchronously, and the threaded transmission effect between the threaded rod 76 and the threaded sleeve 77 is used to drive the slider 73 to move along the slide groove, thereby driving the sliding roller 74 to move synchronously, squeezing and stretching the coiled material on the outer surface, so as to achieve the purpose of adjusting the tension of the coiled material during transportation, and the pump body 122 is used to extract and press the extraction pipe a124 and the extraction pipe b125 into the dust hood 126, so as to absorb the dust and impurities attached to the surface of the coiled material, and the dust is output by the discharge pipe 127 to the collection box 128.

[0034] According to the above working process, it can be known that the present utility model can adjust the tension of the printing coil in real time during transportation through the tension adjustment component 7, so as to avoid the curling or even disorder of the printing coil due to insufficient tension during transportation, and to a certain extent, it can improve the overall printing quality of the final printing coil. It is not only convenient to adjust but also has high structural flexibility and can be adapted to different work requirements.

[0035] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it is worth specifically explaining that a dust removal assembly 12 is provided on one side of the frame 4, and the dust removal assembly 12 includes a mounting plate 121, and the mounting plate 121 is fixed to a side wall of one side of the bracket 71, and a pump body 122 is fixed to one side wall of the mounting plate 121, and two symmetrically distributed connecting plates 123 are fixed to the top side wall of the bracket 71, and a connected extraction pipe a124 is fixed to the output end of the pump body 122, and an extraction pipe b125 is fixed to one side wall of the two connecting plates 123, and the extraction pipe b125 is connected to the extraction pipe a124, and the two extraction pipes b124 are connected to each other.

Through the dust removal assembly 12, the dust and impurities attached to the surface of the printing coil can be absorbed, thereby greatly improving the quality and effect of the printing press on the printing coil, avoiding the situation that the printed product is unqualified due to the influence of dust adhesion, and effectively saving the labor intensity of the staff, and having strong practicality.

[0036] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the outer surfaces of multiple rollers 5 are provided with anti-skid grooves 13, the cross-section of the carrier frame 2 is concave, the vertical cross-section of the bracket 71 is L-shaped, and the angle between the bracket 71 and the base substrate 1 is right-angled. By setting the anti-skid grooves 13, the conveying stability of the rollers 5 when conveying the printed coil can be increased, and the situation in which the rollers 5 idle due to slipping during the conveying of the printed coil can be effectively avoided.

[0037] Further as Figure 5As shown, it is worth explaining in detail that the cross section of the dust hood 126 is arranged in an inverted trapezoidal shape, and the dust hood 126 is located between the two rollers 5. Through the arrangement of the dust hood 126, the dust collection effect on the printing coil is effectively ensured, and the laminating effect is better.

By setting the sliding rail and the central section of the guide roller 3, it is ensured that the guide roller 3 is in a relatively stable state when adjusting the tension of the printing coil.

[0039] In summary: through the shape setting of the slider 73, not only can the slider 73 be lifted and moved in a relatively stable state in the slide groove, but also the displacement caused by the movement of the slider 73 can be avoided. The setting of the anti-slip groove 13 can increase the conveying stability of the roller 5 when conveying the printing coil, and effectively avoid the situation where the roller 5 idles due to slipping during the conveying of the printing coil. Through the setting of the dust hood 126, the dust collection effect of the printing coil is effectively ensured, and the laminating effect is better. Through the setting of the central section of the slide rail and the guide roller 3, it is ensured that the guide roller 3 is in a relatively stable state when adjusting the tension of the printing coil.
