Description

Technical Field

[0001] This utility model relates to the technical field of textile printing and dyeing, specifically to a fabric printing and dyeing roller for textile printing and dyeing. Background Technology

[0002] Roller printing, also known as roller printing, is a high-efficiency, large-volume fabric printing process. Its core component is a large copper roller with recessed patterns engraved on its surface according to the desired design.

[0003] According to Chinese Patent No. CN220183570U, a textile printing and dyeing roller includes a base, a printing and dyeing component, and a drying component. A printing and dyeing box and a drying box are fixedly installed on the top of the base, and adjacent side walls of the printing and dyeing box are fixedly installed. The printing and dyeing component is located on the printing and dyeing box and includes a sponge and a printing and dyeing roller. During rotation, the printing and dyeing roller adheres dye to the sponge, resulting in uniform dye adhesion to the surface of the printing and dyeing roller. The drying component is located on the drying box and includes an air outlet box, a heating box, a heating tube, a fan, and a conveying pipe. The fan delivers filtered airflow to the interior of the heating box, the heating tube heats the airflow, and the conveying pipe delivers the hot airflow to the interior of the air outlet box for discharge, thus drying the printed and dyed fabric.

[0004] In the above scheme, the dyeing roller is used to dip the dye on the sponge for dyeing and printing, which still has the following disadvantages: when dyeing and printing the fabric, the dyeing roller can only dye and print the bottom side of the fabric at a time, and a second dyeing and printing is required. Utility Model Content

[0005] The purpose of this invention is to provide a textile printing roller to solve the problem that when printing rollers are used to print fabric, they can only print the bottom surface of the fabric at a time, requiring a second printing process.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a fabric printing and dyeing roller for textile printing and dyeing, including a pressing roller, the pressing roller being rotatably disposed inside the printing and dyeing pool, the top surface of the printing and dyeing pool having mounting grooves on both sides, a protective roller being rotatably disposed inside the mounting grooves, positioning grooves being respectively disposed on both sides of the printing and dyeing pool, and positioning plates being rotatably disposed at both ends of the pressing roller, the positioning grooves and positioning plates being slidably engaged.

[0007] Preferably, limit grooves are formed on both sides of the interior of the positioning groove, and limit strips are fixed on both sides of the positioning plate, with the limit grooves and limit strips slidingly engaged.

[0008] Preferably, a supporting folding plate is fixed to the top surface of the dyeing and printing pool, a fixed folding plate is provided inside the supporting folding plate, a pressing roller is rotatably provided inside the fixed folding plate, a cylinder is provided on the top surface of the supporting folding plate, and one end of the cylinder telescopic rod passes through the supporting folding plate and is fixed to the top surface of the fixed folding plate.

[0009] Preferably, the top surface of the supporting folding plate has two sliding holes, and the top surface of the fixed folding plate has two sliding rods fixed thereon, with the sliding holes and sliding rods slidably inserted into each other.

[0010] Preferably, a base is fixed to the bottom surface of the dyeing and printing pool, and a drying box is fixed to the top surface of the base. A warm air fan is provided on one side of the drying box, and the air outlet pipe of the warm air fan passes through one side of the drying box and extends into the interior of the drying box. Both sides of the drying box are provided with through openings.

[0011] Preferably, the top surface of the base is fixed with a plurality of support plates, wherein two support plates form a group, and a support roller is rotatably arranged between the two support plates in each group.

[0012] Compared with existing technologies, a textile printing and dyeing roller that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] 1. By pressing the fabric into the dye through the pressing roller, the fabric can be fully contacted with the dye, and both sides of the fabric can be fully dyed and printed in one go, without the need for secondary dyeing and printing, thus increasing the efficiency of fabric dyeing and printing.

[0014] 2. When the fabric slides out of the dyeing pool and passes over the right protective roller, the telescopic rod of the cylinder extends downward during operation, which pushes the fixed folding plate downward, thereby causing the extrusion roller to slide downward and press the extrusion roller against the surface of the protective roller. At the same time, the sliding rod slides up and down inside the sliding hole, which increases the stability of the extrusion roller when it moves up and down. By applying opposing forces to the fabric through the extrusion roller and the right protective roller, excess dye can be squeezed out of the fabric, preventing excessive dye from existing in the fabric.

[0015] Third, during the dyeing and printing process, the two ends of the fabric are supported upward by support rollers. The fabric that slides out of the dyeing and printing pool passes through the penetration hole and enters the drying box. The temperature inside the drying box is increased by the warm air blower, which dries the fabric and makes it easier to roll up and store the dyed and printed fabric later.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 2 and Figure 3 As shown, a textile printing and dyeing roller includes a pressing roller 2, which is rotatably disposed inside a dyeing pool 1. Mounting grooves 3 are provided on both sides of the top surface of the dyeing pool 1. A protective roller 4 is rotatably disposed inside the mounting grooves 3. Positioning grooves 5 are provided on both sides of the dyeing pool 1. Positioning plates 6 are rotatably disposed at both ends of the pressing roller 2. The positioning grooves 5 and positioning plates 6 are slidably engaged. Limiting grooves 7 are provided on both sides of the interior of the positioning grooves 5. Limiting strips 8 are fixed on both sides of the positioning plates 6. The limiting grooves 7 and limiting strips 8 are slidably engaged.

[0023] In use, the staff first adds dye to the inside of the dyeing pool 1. The fabric will first pass over the top of the left protective roller 4 on the dyeing pool 1, then pass under the pressing roller 2, and finally pass over the top of the right protective roller 4 on the dyeing pool 1. The weight of the pressing roller 2 can then press the fabric into the dye inside the dyeing pool 1, thus dyeing the fabric. Depending on the fabric, the staff can pull out the positioning plate 6 from the positioning groove 5, then replace the pressing roller 2 with one of different weights, and slide the positioning plate 6 into the center of the positioning groove 5. At the same time, the limiting strip 8 is inserted into the limiting groove 7 to prevent the pressing roller 2 from shifting during the dyeing process.

[0024] By pressing the fabric into the dye using the pressing roller 2, the fabric can be fully contacted with the dye, allowing both sides of the fabric to be fully dyed and printed in one go, eliminating the need for secondary dyeing and printing, thus increasing the efficiency of fabric dyeing and printing.

[0025] like Figure 3 and Figure 4As shown, a supporting folding plate 9 is fixed on the top surface of the dyeing and printing pool 1. A fixed folding plate 10 is provided inside the supporting folding plate 9. A pressing roller 11 is rotatably arranged inside the fixed folding plate 10. A cylinder 12 is provided on the top surface of the supporting folding plate 9. One end of the telescopic rod of the cylinder 12 passes through the supporting folding plate 9 and is fixed to the top surface of the fixed folding plate 10. Two sliding holes 13 are opened on the top surface of the supporting folding plate 9. Two sliding rods 14 are fixed on the top surface of the fixed folding plate 10. The sliding holes 13 and the sliding rods 14 are slidably inserted.

[0026] During use, when the fabric slides out from inside the dyeing pool 1 and passes over the right protective roller 4, the telescopic rod extending downward from the cylinder 12 pushes the fixed folding plate 10 downward, which in turn drives the squeezing roller 11 to slide downward and press the squeezing roller 11 against the surface of the protective roller 4. At the same time, the sliding rod 14 slides up and down inside the sliding hole 13, which increases the stability of the squeezing roller 11 when it moves up and down. By applying opposing forces to the fabric through the squeezing roller 11 and the right protective roller 4, excess dye can be squeezed out of the fabric, preventing excessive dye from existing in the fabric.

[0027] like Figure 1 and Figure 3 As shown, a base 20 is fixed to the bottom surface of the dyeing and printing pool 1, and a drying box 15 is fixed to the top surface of the base 20. A warm air blower 16 is provided on one side of the drying box 15. The air outlet pipe of the warm air blower 16 passes through one side of the drying box 15 and extends into the interior of the drying box 15. Both sides of the drying box 15 are provided with through holes 17. Several support plates 18 are fixed to the top surface of the base 20, with two support plates 18 forming a group. A support roller 19 is rotatably arranged between the two support plates 18 in each group.

[0028] During use, the fabric is supported upward by the support rollers 19 at both ends during the dyeing and printing process. The fabric slides out of the dyeing and printing pool 1 and passes through the through hole 17 into the drying box 15. The temperature inside the drying box 15 is increased by the warm air blower 16, which dries the fabric and makes it easier to roll up and store the dyed and printed fabric later.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
