Description

Technical Field

[0001] The utility model relates to fabric dyeing equipment, in particular to a high-efficiency energy-saving dyeing drum device. Background Art

[0002] A bobbin dyeing machine is a dyeing device used for yarn or fabric. The yarn or fabric needs to be wound onto a dyeing bobbin with through holes on the surface. The dyeing bobbins are then stacked one by one and inserted into the creel of the dyeing machine. Dyeing agents and other substances enter the interior from the bottom of the dyeing bobbin and penetrate through the through holes on the dyeing bobbin to the yarn or fabric wrapped around the outer wall of the dyeing bobbin. The dye penetrates from the inside out until all the yarn or fabric is soaked, thus achieving more uniform dyeing.

[0003] Excluding the perforated areas, the smooth outer circumference of the dyeing bobbin's exterior surface closely adheres to the dyed material. These areas actually have low water permeability, sometimes even worse than other areas. To improve permeability, the perforated density can be increased to reduce the actual perforated area. However, as the perforated density increases, the strength of the dyeing bobbin decreases, making it impossible to further reduce the perforated area. The ratio of the actual perforated area to the total area of ​​existing dyeing bobbins is limited to approximately 0.5. See Appendix 1 for details. Figure 5 Therefore, due to the threshold limit of the dye permeability efficiency of existing dyeing tubes, the dyeing efficiency of fabrics and yarns cannot be further improved, and the operating time of the equipment cannot be further shortened. Summary of the Invention

[0004] The utility model provides a high-efficiency and energy-saving dyeing drum device, which solves the problem in the prior art that the threshold value of the dye water permeability efficiency limits the production efficiency.

[0005] The above-mentioned technical problems of the present invention are mainly solved by the following technical solutions: A high-efficiency and energy-saving dyeing drum device includes a dyeing drum body, which is composed of a drum body, a first baffle ring and a second baffle ring. The drum body is made of stainless steel, and a plurality of water-permeable holes are densely distributed on the drum body. The inner sides of the two baffle rings are formed with sleeve holes, and the aperture of the sleeve holes is smaller than the inner diameter of the drum body. The two baffle rings are provided with communicating holes / communicating grooves connected to the inner cavity of the drum body. The outer side of the drum body is sleeved with a winding drum made of plastic material, and the length of the winding drum is consistent with that of the drum body. The outer wall of the winding drum is provided with a plurality of ridges distributed in a circumferential array, and an outer guide groove is formed between adjacent ridges. The inner wall of the winding drum is formed with a plurality of annular guide grooves distributed at intervals, and the bottom of the annular guide groove partially penetrates the outer guide groove, so that the annular guide groove and the outer guide groove are connected inside and outside. The inner wall of the winding drum is also provided with a fitting ring that fits with the outer wall of the drum. The winding drum has a relatively complex structure and is difficult and costly to manufacture using metal materials. It is generally formed by integral plastic injection molding.

[0006] The utility model is sleeved on the creel of the dyeing machine during dyeing, the two sleeve connecting holes match the outer diameter of the creel, an annular cavity for circulating dye is formed between the inner wall of the cylinder and the creel, and the communicating hole / communicating groove is used to connect the cavities on the upper and lower sides of the retaining ring, so as to facilitate the mutual circulation of dye; the dye inside the cylinder can enter the outside of the cylinder through the water-permeable hole, the outside of the cylinder is sleeved with a winding cylinder, and the annular guide groove inside the winding cylinder can connect the dye with the outer guide groove, so that the dye can penetrate from the inside to the outside into the material to be dyed.

[0007] The winding drum in this utility model is used to wind fabric or yarn. The top area of ​​the ridges on the winding drum is the actual contact area with the fabric / yarn. The ridges are narrow, so the ratio of the actual contact area to the opening area is much less than 0.5. The winding drum also has an internal cylindrical body as a support structure, ensuring sufficient overall strength.

[0008] Furthermore, the fitting ring is provided with a plurality of inner guide grooves, which pass through both sides of the fitting ring, so that the cavities on both sides of the fitting ring can also be connected. At the same time, the water-permeable holes covered by the fitting ring can also communicate with the inner guide grooves, thereby increasing the overall water permeability.

[0009] Furthermore, a positioning inner ring is coaxially provided on the outer wall of the first retaining ring, and a positioning outer ring is coaxially provided on the outer wall of the second retaining ring, wherein the outer contour of the positioning inner ring is adapted to the inner contour of the positioning outer ring. When two of the present inventions are stacked on each other, the positioning outer ring can be mutually sleeved with the positioning inner ring to achieve axial positioning.

[0010] Therefore, compared with the prior art, the present invention has the following characteristics: 1. The winding drum is used for winding fabrics or yarns, and the top area of ​​the ridges on the winding drum is the actual contact and fitting area with the fabric / yarn. The width of the ridges is relatively narrow, so the ratio of the actual fitting area to the opening area is much less than 0.5, so it has an extremely high dye transmittance, so that the dyeing effect per unit time is higher, and the time required for dyeing the same volume of fabric is greatly reduced, which is conducive to saving equipment energy consumption. At the same time, there is a cylinder body inside the winding drum as a support body, so the overall strength is sufficient. BRIEF DESCRIPTION OF THE DRAWINGS

The drum body is made of stainless steel and is densely covered with a plurality of water-permeable holes 11. The total area of ​​the water-permeable holes accounts for a ratio of 0.2 to 0.4 of the surface area of ​​the drum body. The inner sides of the two baffle rings are formed with a sleeve hole 40. The aperture of the sleeve hole is smaller than the inner diameter of the drum body. The two baffle rings are provided with a connecting groove 41 connected to the inner cavity of the drum body. The outer surface of the drum body is provided with a winding drum 50 made of plastic material. The length of the cylinder is consistent with that of the cylinder body. The outer wall of the winding cylinder is provided with a plurality of ridges 51 distributed in a circumferential array. An outer guide groove 52 is formed between adjacent ridges. The inner wall of the winding cylinder is provided with a plurality of annular guide grooves 53 distributed at intervals. The bottom of the annular guide groove partially penetrates the outer guide groove, so that the annular guide groove and the outer guide groove are connected inside and outside. The inner wall of the winding cylinder is also provided with a fitting ring 54 that fits with the outer wall of the cylinder. The ratio of the top width of the ridge to the maximum width of the outer guide groove is 1:2-5 (see Figure 6 ), so the ratio of the corresponding actual bonding area to the total area is much less than 0.5.

[0020] This embodiment is mounted on the creel of the dyeing machine during dyeing, and the two connecting holes match the outer diameter of the creel. An annular cavity for circulating dye is formed between the inner wall of the cylinder and the creel, and the connecting groove is used to connect the cavities on the upper and lower sides of the retaining ring to facilitate the mutual circulation of dye; the dye inside the cylinder can enter the outside of the cylinder through the water-permeable hole, and a winding cylinder is mounted on the outside of the cylinder. The annular guide groove inside the winding cylinder can connect the dye with the outer guide groove, so that the dye can penetrate from the inside to the outside into the material to be dyed.

[0021] See Figure 3 The fitting ring is provided with a plurality of inner guide grooves 55, which pass through both sides of the fitting ring, so that the cavities on both sides of the fitting ring can also be conducted. At the same time, some of the water-permeable holes covered by the fitting ring can also communicate with the inner guide grooves, thereby increasing the overall water permeability.

[0022] See Figure 2 The inner side surfaces of the first and second retaining rings are coaxially provided with sleeves 60, which are fixedly sleeved with the inner surface of the cylinder; the outer wall of the sleeve is provided with external threads 61, and the inner walls of both ends of the cylinder are provided with internal threads 12.
