Description

Technical Field

[0001] The utility model relates to the technical field of rotary screen printing, and more particularly to an adjusting device for a rotary screen printing unit. Background Art

[0002] Rotary screen printing is a continuous printing process. The fabric is transported to the continuously moving rotary screen cylinder through a wide rubber belt. The rotary screen is round. During printing, the rotary screen is rolled on the cloth surface for printing. A scraper is used to print the color paste in the rotary screen onto the fabric under pressure.

[0003] At present, the existing rotary screen printing device is equipped with an adjustment mechanism, which adjusts the distance between the upper roller and the lower roller to meet the printing needs of fabrics of different thicknesses. The equipment can also ensure that the color paste is evenly distributed during the printing process while avoiding unnecessary pressure or damage to the fabric, thereby improving the accuracy and efficiency of printing.

[0004] However, the existing device has a single function and only improves the printing effect by adjusting the distance between the upper roller and the lower roller. However, when adjusting in the vertical direction, different tensions will still occur due to thickness deviations at different positions of the fabric, thereby affecting the printing effect of the fabric. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an adjustment device for a rotary screen printing unit.

[0006] To achieve the above objectives, the present invention provides the following technical solutions: an adjustment device for a rotary screen printing unit, comprising a main body assembly, two lifting assemblies installed inside the main body assembly, and an adjustment assembly installed on the top of the main body assembly.

[0007] The main assembly includes a base and vertical plates symmetrically installed on both sides of the top of the base. A lower roller is rotatably connected between the two vertical plates. The two groups of lifting assemblies are respectively connected to the two ends of the lower roller. An upper roller is arranged above the lower roller.

[0008] The adjustment assembly includes fixed plates respectively installed on the top of two vertical plates, wherein a support plate is vertically installed on the top of one of the fixed plates, and an arc-shaped groove is opened on the side wall of the support plate. A sliding rod is slidably connected to the inside of the arc-shaped groove, and one end of the sliding rod is connected to a bracket, and the upper roller is rotatably connected to the inside of the bracket.

[0009] The utility model is further configured as follows: a through groove is opened on the side walls of the two vertical plates, a lifting cylinder is vertically installed inside the through groove, the piston rod of the lifting cylinder is connected to a slider, and the two ends of the lower roller are respectively rotatably connected to the inside of the two sliders.

[0010] The utility model is further configured as follows: the diameter of the lower roller is greater than the diameter of the upper roller; a first drive motor is installed on one side of one of the sliders; and the output end of the first drive motor is connected to one end of the vertical plate.

[0011] By adopting the above technical solution, the upper roller and the lower roller are used in combination, and the fabric passes between the two to form a predetermined flower pattern on the fabric. The lifting cylinder is used to push the slider up and down, thereby adjusting the height of the slider. The slider drives the lower roller to move up and down, thereby adjusting the distance between the lower roller and the fabric to adapt to the printing of fabrics of different thicknesses. The bracket and the upper roller are driven by an adjusting motor to move. The bracket drives the slide bar to slide inside the arc groove, and the bracket drives the upper roller to swing, thereby squeezing the fabric passing between the upper roller and the lower roller. The fabric is wrapped and pressed on the surface of the lower roller, increasing the contact area between the fabric and the lower roller, and the fabric is pulled, thereby adjusting the tension of the fabric to alleviate the situation where different fabric tensions affect the fabric printing effect.

[0012] The utility model is further configured as follows: a mounting plate is vertically installed on the top of the fixed plate above the first drive motor, an adjustment motor is installed on one side of the mounting plate, and the output end of the adjustment motor passes through the mounting plate and is connected to one side of the bracket.

[0013] The utility model is further configured as follows: a second drive motor is installed on the side wall of the bracket, an output end of the second drive motor is connected to one end of the upper roller, and first inclined portions are provided on both sides of the top of the support plate.

[0014] The utility model is further configured as follows: two second inclined portions are symmetrically provided on both sides of the top of the vertical plate.

[0015] By adopting the above technical solution, the support plate and the vertical plate are prevented from interfering with the second drive motor when the second drive motor is synchronously displaced.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] (1) By setting up a bracket and using an adjustable motor to drive the bracket and the upper roller to move, the bracket drives the slide bar to slide inside the arc groove, and the bracket drives the upper roller to swing, thereby squeezing the fabric passing between the upper roller and the lower roller. The fabric is surrounded and pressed on the surface of the lower roller, increasing the contact area between the fabric and the lower roller, and the fabric is pulled, thereby adjusting the tension of the fabric, alleviating the situation where different fabric tensions affect the fabric printing effect.

[0027] Example 1, see Figure 1 An adjustment device for a rotary screen printing unit includes a main component 1 and two sets of lifting components 2 installed inside the main component 1. The main component 1 is used for printing fabrics, and the lifting components 2 are used to adjust the height of the printing structure to adapt to printing fabrics of different thicknesses.

[0028] See Figure 1 and Figure 2The main body component 1 includes a base 11 and vertical plates 12 symmetrically installed on both sides of the top of the base 11. A lower roller 13 is rotatably connected between the two vertical plates 12. Two sets of lifting components 2 are respectively connected to the two ends of the lower roller 13. A through groove 21 is opened on the side walls of the two vertical plates 12. A lifting cylinder 22 is vertically installed inside the through groove 21. The piston rod of the lifting cylinder 22 is connected to a slider 23. The two ends of the lower roller 13 are rotatably connected to the inside of the two sliders 23. The lifting cylinder 22 is used to push the slider 23 up and down, thereby adjusting the height of the slider 23. The slider 23 drives the lower roller 13 to rise and fall, thereby adjusting the distance between the lower roller 13 and the fabric to adapt to printing of fabrics of different thicknesses. A first driving motor 15 is installed on one side of one of the sliders 23. The output end of the first driving motor 15 is connected to one end of the vertical plate 12. The first driving motor 15 provides driving force for the rotation of the lower roller 13.

[0029] See Figure 1 and Figure 2 An upper roller 14 is positioned above the lower roller 13. The diameter of the lower roller 13 is larger than that of the upper roller 14. Color paste is prepared according to process requirements. The upper and lower rollers 14 and 13 work together, and the fabric passes between them, forming a predetermined pattern on the fabric. During operation, the fabric is manually fed to the upper and lower rollers 14 and 13, and the pre-assembled upper and lower rollers 14 and 13 are installed. The dye, water, and paste required for printing are automatically delivered under computer control, achieving a color paste uptake rate of 85% to 90%. After printing, the fabric surface is dried using direct natural gas combustion.

[0030] See Figure 2 and Figure 3 An adjustment component 3 is installed on the top of the main component 1. The adjustment component 3 is used to adjust the angle of the upper roller 14 to meet the fabric printing needs under different tension conditions. The adjustment component 3 includes fixed plates 31 respectively installed on the top of the two vertical plates 12. A support plate 32 is vertically installed on the top of one of the fixed plates 31. The side wall of the support plate 32 is provided with an arc groove 33. The inside of the arc groove 33 is slidably connected to a slide rod 38. One end of the slide rod 38 is connected to a bracket 34. The upper roller 14 is rotatably connected to the inside of the bracket 34.

[0031] See Figure 2 and Figure 3 In this embodiment, a mounting plate 36 is vertically installed on the top of the fixed plate 31 above the first drive motor 15, and an adjusting motor 37 is installed on one side of the mounting plate 36. The output end of the adjusting motor 37 passes through the mounting plate 36 and is connected to one side of the bracket 34.

[0032] The upper roller 14 is supported by a bracket 34, and one end of the bracket 34 is supported by an adjusting motor 37 and a mounting plate 36, and the other end of the bracket 34 is supported by a support plate 32 and a slide bar 38. When the upper roller 14 needs to be adjusted, the bracket 34 and the upper roller 14 are driven to move by the adjusting motor 37, and the bracket 34 drives the slide bar 38 to slide inside the arc groove 33, and the bracket 34 drives the upper roller 14 to swing, thereby squeezing the fabric passing between the upper roller 14 and the lower roller 13, and the fabric is wrapped and pressed on the surface of the lower roller 13, increasing the contact area between the fabric and the lower roller 13, and the fabric is pulled, thereby adjusting the tension of the fabric, thereby alleviating the situation where different fabric tensions affect the printing effect of the fabric.

[0033] See Figure 2 and Figure 3 A second drive motor 35 is installed on the side wall of the bracket 34, and the output end of the second drive motor 35 is connected to one end of the upper roller 14. The second drive motor 35 is used to drive the upper roller 14 to rotate, and the rotation directions of the upper roller 14 and the lower roller 13 are set in opposite directions. When the bracket 34 and the upper roller 14 swing, a first inclined portion is opened on both sides of the top of the support plate 32, and two second inclined portions are symmetrically opened on both sides of the top of the vertical plate 12. This setting prevents the support plate 32 and the vertical plate 12 from interfering with the second drive motor 35 when the second drive motor 35 is synchronously displaced.

[0034] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
