[0007] An inclined plate is fixed inside the dyeing chamber. The inclined plate includes an inclined upper end and an inclined lower end. The inclined upper end is close to the dyeing discharge trough and is higher than the inclined lower end. The upper side of the inclined plate is provided with a plurality of liquid inlet grooves and a pressing surface corresponding to each of the liquid inlet grooves.

[0008] A compression support is disposed within the dyeing chamber, and a plurality of compression rollers are rotatably connected to the compression support, with each compression roller corresponding to a compression surface.

[0009] Furthermore, the inclined plate is also provided with a liquid guiding cavity, the liquid inlet groove is connected to the liquid guiding cavity, and the liquid guiding cavity is provided with a liquid guiding groove on the side wall near the lower end of the inclined plate.

[0011] Furthermore, an electric push rod is fixed inside the staining chamber via a connecting bracket, and the push rod of the electric push rod is fixedly connected to the squeezing bracket.

[0012] Furthermore, a fixing post is fixed on the filter plate, and the fixing post is provided with a connecting threaded hole. The extrusion bracket is provided with a connecting hole corresponding to the fixing post, and a connecting bolt passes through the connecting hole. The connecting bolt is threadedly connected to the connecting threaded hole.

[0013] Furthermore, it also includes a filter box, which is fixed inside the staining chamber. The filter box has an upward-facing filter cavity, and the bottom of the filter cavity has several second filter holes. The filter box is located below the liquid guiding groove.

[0014] Furthermore, the outer wall of the filter box is provided with a fixing threaded hole, and the side wall of the dyeing box is provided with a fixing through hole, and a fixing bolt that is threadedly connected to the fixing threaded hole passes through the fixing through hole.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] (1) Each extrusion roller presses the fabric against the corresponding extrusion surface. The extrusion roller squeezes out the water in the fabric. The squeezed water will flow into the liquid inlet groove below the extrusion surface, without affecting the fabric below. Each extrusion roller can squeeze the fabric multiple times, so that more liquid in the fabric is squeezed out.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 This utility model provides a technical solution for a short-process printing and dyeing device for textile fabrics.

[0028] A short-process dyeing and printing apparatus for textile fabrics, comprising:

[0029] The dyeing box 1 has a dyeing chamber 2 inside. The dyeing chamber 2 has a dyeing feed trough 3 and a dyeing discharge trough 4 at both ends. Several guide rollers 5 are rotatably connected inside the dyeing chamber 2.

[0030] Inclined plate 6 is fixed inside the dyeing chamber 2. Inclined plate 6 includes an inclined upper end 7 and an inclined lower end 8. The inclined upper end 7 is close to the dyeing discharge trough 4 and is higher than the inclined lower end 8. The upper side of the inclined plate 6 is provided with a plurality of liquid inlet grooves 9 and an extrusion surface 10 corresponding to the liquid inlet grooves 9.

[0031] The extrusion support 11 is set inside the dyeing chamber 2. Several extrusion rollers 12 are rotatably connected to the extrusion support 11, and the extrusion rollers 12 correspond one-to-one with the extrusion surface 10.

[0032] Fabric 27 enters the dyeing chamber 2 from the dyeing feed trough 3, and then exits from the dyeing discharge trough 4 after passing through each guide roller 5. Each squeeze roller 12 brings the fabric 27 into contact with the corresponding squeeze surface 10. The squeeze roller 12 squeezes out the water in the fabric 27. The squeezed water flows into the liquid inlet groove 9 below the squeeze surface 10 without affecting the fabric 27 below. Each squeeze roller 12 can squeeze the fabric 27, so that more liquid is squeezed out of the fabric 27.

[0033] like Figure 4 and Figure 5 The inclined plate 6 is also provided with a liquid guiding cavity 13, which is located below the liquid inlet groove 9. The liquid inlet groove 9 is connected to the liquid guiding cavity 13. The side wall of the liquid guiding cavity 13 near the inclined lower end 8 is provided with a liquid guiding groove 14.

[0034] The squeezed liquid enters the liquid guiding cavity 13 through the liquid inlet groove 9, and then flows back to the dyeing cavity 2 through the liquid guiding channel 14, making full use of the squeezed liquid.

[0035] like Figure 4 As shown, the inclined plate 6 has an upward-facing slot 15 located near the lower end 8 of the inclined plate. A filter plate 16 is inserted into the slot 15, and the filter plate 16 has several first filter holes 17. The first filter holes 17 on the filter plate 16 can filter the liquid flowing out from the liquid guide channel 14, reducing the backflow of some impurities in the liquid into the staining chamber 2. When the filter plate 16 needs to be replaced or cleaned, it can be directly removed from the slot 15.

[0036] like Figure 3 As shown, an electric push rod 18 is fixed inside the dyeing chamber 2 via a connecting bracket 28. The push rod of the electric push rod 18 is fixedly connected to the extrusion bracket 11. The electric push rod 18 can drive the extrusion bracket 11 to move, thereby adjusting the pressure of the extrusion roller 12 on the fabric 27.

[0037] like Figure 4 As shown, a fixing post 19 is fixed on the filter plate 16, and the fixing post 19 has a connecting threaded hole 20. The extrusion bracket 11 has a connecting hole 21 corresponding to the fixing post 19, and a connecting bolt 29 passes through the connecting hole 21. When it is necessary to disassemble the filter plate 16, the connecting bolt 29 can be threaded into the connecting threaded hole 20, and then the push rod of the electric push rod 18 can be retracted to bring the filter plate 16 away from the slot 15. Then, the filter plate 16 can be held and the connecting bolt 29 can be unscrewed, making the disassembly of the filter plate 16 more convenient. During normal printing and dyeing, the connecting bolt 29 can be removed without using it.

[0038] like Figure 4As shown, the short-process dyeing and printing apparatus for textile fabric 27 also includes a filter box 22, which is fixed inside the dyeing chamber 2. The filter box 22 has an upward-facing filter cavity 23, and the bottom of the filter cavity 23 has several second filter holes 24. The filter box 22 is located below the liquid guiding channel 14. The second filter holes 24 of the filter box 22 can filter the liquid flowing from the liquid guiding channel 14.

[0039] The outer wall of the filter box 22 is provided with a fixing threaded hole 25, and the side wall of the dyeing chamber 1 is provided with a fixing through hole. A fixing bolt 26, which is threaded to the fixing threaded hole 25, passes through the fixing through hole. The filter box 22 is fixed in the dyeing chamber 2 by the fixing bolt 26. When the filter box 22 needs to be disassembled, it is only necessary to remove the fixing bolt 26.

[0040] Of course, the extruded fabric then goes through a drying box to dry it.

[0041] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
