Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing equipment, in particular to a cooling roller and textile equipment. Background Art

[0002] A stenter machine is a type of equipment used in textile processing, primarily for shaping textiles in both the warp and weft directions to improve their dimensional stability, flatness, and appearance. Heating rollers and cooling rollers are the mechanical components of a stenter machine. During operation, the heating rollers heat the fabric to the desired temperature and shape. The cooling rollers then cool the fabric rapidly and stabilize its shape. This alternating heating and cooling process ensures uniform stress on the fabric during cooling, preventing wrinkles or deformation. Therefore, ensuring rapid cooling of the fabric by the cooling rollers is a key challenge.

[0003] Conventional cooling rollers typically continuously deliver cooling water. Fabric, upon contact with the roller's surface, is rapidly cooled by the flowing cooling water, rapidly removing heat from the fabric. However, due to mechanical limitations, the heat absorbed by the cooling water accumulates within the roller and is difficult to release. This results in low heat exchange efficiency, further impacting the roller's cooling effect on the fabric and, consequently, its physical properties.

[0030] It is particularly important to note that, in this utility model, "axial direction" refers to the direction along which Figure 1 The direction of the axis A shown in FIG.

[0031] Please refer to Figures 1 to 6 As shown, the present invention shows a specific embodiment of a cooling roller 10. The cooling roller 10 can be specifically configured at the cloth outlet end of a heating box (not shown) contained in a textile equipment (not shown, for example, a stenter setting machine), and the heating box performs heat treatment on the fabric, and after heating, the fabric contacts the surface of the cooling roller 10, and the cooling water inside the cooling roller 10 absorbs the heat of the fabric to quickly cool the fabric. It should be noted that the cooling roller 10 and the textile equipment disclosed in this application include but are not limited to various fabrics such as warp knitting, weft knitting, chemical fiber fabrics, coating, wool, cotton, polyester and cloth, and in each embodiment of this application, textiles made of polyester fabrics are used as an example to illustrate, and are applicable to other types of fabrics. Those skilled in the art can reasonably select specific parameters such as the cooling temperature of the cooling roller 10 according to the different objects processed by the cooling roller 10 and the textile equipment.

[0032] Ginseng Figure 1As shown, the cooling roller 10 includes a cooling roller body 11 having a gas flow channel 91, a first hollow shaft 12 and a second hollow shaft 13 axially disposed at both ends of the cooling roller body 11, and at least one fan blade 14 disposed within the gas flow channel 91 and rotatable axially. The cooling roller body 11 includes an outer roller body 111 and an inner roller body 112 nested together, with a gap between the outer roller body 111 and the inner roller body 112 to form an annular liquid flow channel 92. The gas flow channel 91 is formed inside the inner roller body 112. The first hollow shaft 12 and the second hollow shaft 13 are respectively connected to the ends of the liquid flow channel 92. A first through hole 115 and a second through hole 119 are respectively formed at both ends of the cooling roller body 11 for gas to circulate within the gas flow channel 91.

[0033] When the fabric is cooled by the cooling roller 10, the driving assembly (not shown) drives the cooling roller 10 to rotate axially. During the rotation, cooling water is transported to the liquid flow channel 92 through the first hollow shaft 12 or the second hollow shaft 13, and the cooling water in the liquid flow channel 92 is discharged through the second hollow shaft 13 or the first hollow shaft 12, thereby absorbing the heat of the fabric through the cooling water flowing inside the cooling roller body 11; at the same time, during the rotation of the cooling roller 10, the fan blades 14 arranged on the inner side of the inner roller body 112 are driven to rotate axially, and promote the gas to flow into the gas flow channel 91 from the first through hole 115 or the second through hole 119 and be discharged from the second through hole 119 or the first through hole 115, so that the heat absorbed by the cooling water is quickly discharged through the flowing gas, thereby improving the heat exchange efficiency of the cooling water, thereby ensuring the cooling effect of the cooling roller 10 on the fabric, and solving the problem of low heat exchange efficiency of the cooling water in the prior art due to the accumulation of heat absorbed by the cooling water inside the cooling roller and difficulty in releasing it.

[0034] It should be noted that, in the present application, cooling water can be delivered to the liquid flow channel 92 through the first hollow shaft 12, and the cooling water in the liquid flow channel 92 can be discharged through the second hollow shaft 13; cooling water can also be delivered to the liquid flow channel 92 through the second hollow shaft 12, and the cooling water in the liquid flow channel 92 can be discharged through the first hollow shaft 13. This embodiment does not specifically limit this, and in the following description, the example of the first hollow shaft 12 delivering cooling water and the second hollow shaft 13 outputting cooling water is used as an example for illustrative purposes. Similarly, with respect to the first through hole 115 and the second through hole 119, gas can be delivered to the gas flow channel 91 through the first through hole 115, and the gas in the gas flow channel 91 can be discharged through the second through hole 119; gas can also be delivered to the gas flow channel 91 through the second through hole 119, and the gas in the gas flow channel 91 can be discharged through the second through hole 119. The direction of gas flow is related to the direction of axial rotation of the cooling roller 10, and this embodiment does not specifically limit this. At the same time, a drain outlet 191 is opened on the side of the cooling roller body 11 to discharge the sewage in the cooling roller body 11, and a movable plug 192 for movably closing the drain outlet 191 is set at the drain outlet 191. When the sewage in the cooling roller body 11 needs to be discharged, the drain outlet 191 is opened by the movable plug 192 to realize the discharge of sewage.

[0035] Ginseng Figure 1 As shown, the cooling roller body 11 further includes: a first plate body 113 and a second plate body 114, respectively disposed at both ends of the outer roller body 111 and the inner roller body 112, to seal the ends of the cooling roller body 11. A first through hole 115 and a second through hole 119 are respectively provided in the first plate body 113 and the second plate body 114. This facilitates the assembly of the first hollow shaft 12 and the second hollow shaft 13, enhances the strength of the entire cooling roller body 11, and ensures smooth flow of gas within the gas flow channel 91, thereby ensuring that the gas effectively removes heat absorbed by the cooling water, thereby improving the heat exchange efficiency of the cooling water to the fabric. Preferably, the first through hole 115 is provided on the circumference of the first hollow shaft 12, and the second through hole 119 is provided on the circumference of the second hollow shaft 13, to further ensure smooth flow within the gas flow channel 91.

[0036] Regarding the assembly method of the first hollow shaft 12 and the second hollow shaft 13, the first hollow shaft 12 can be detachably assembled on the outside of the first plate body 113 through the first locking assembly 15, and the second hollow shaft 13 can be detachably assembled on the outside of the second plate body 114 through the second locking assembly 16, thereby facilitating the replacement or regular maintenance of the first hollow shaft 12 and / or the second hollow shaft 13.

[0037] More specifically, Figures 1 to 3As shown, the cooling roller body 11 further includes: a first liquid guide tube 116 and a second liquid guide tube 117, respectively disposed at both ends of the inner side of the inner roller body 112 and communicating with the liquid flow channel 92. The first liquid guide tube 116 axially penetrates the first plate body 113 and connects to the first hollow shaft 12, while the second liquid guide tube 117 axially penetrates the second plate body 114 and connects to the second hollow shaft 13. The first locking assembly 15 includes: a first clamping plate 151 sleeved on the outside of the end of the first liquid guide tube 116 and a first bearing 152 sleeved on the outside of the end of the first hollow shaft 12. A first locking member (not shown) continuously penetrates the first bearing 152, the first clamping plate 151, and the first plate body 113 to achieve detachable assembly of the first hollow shaft 12 on the outside of the first plate body 113. The second locking assembly 16 includes: a second clamping plate 161 sleeved on the outside of the end of the second liquid guide tube 117 and a second bearing 162 sleeved on the outside of the end of the second hollow shaft 13. A second locking member (not shown) continuously penetrates the second bearing 162, the second clamping plate 161 and the second plate body 114 to enable the second hollow shaft 13 to be detachably assembled on the outside of the second plate body 114.

[0038] It should be noted that the cooling water flows from the first hollow shaft 12 into the first liquid guide tube 116, and flows into the liquid flow channel 92 formed between the outer roller body 111 and the inner roller body 112 through the first liquid guide tube 116, and then discharges the liquid flow channel 92 through the second liquid guide tube 117, and discharges the second liquid guide tube 117 from the second hollow shaft 13, thereby realizing the flow of liquid in the liquid flow channel 92.

[0039] Ginseng Figure 1 As shown, in order to prevent the cooling roller body 11 from being deformed during use, which in turn affects the blockage of the cooling water in the liquid flow channel 92, a number of reinforcing ribs 118 are evenly arranged between the outer roller body 111 and the inner roller body 112, thereby supporting the outer roller body 111 and the inner roller body 112 on both sides of the reinforcing ribs 118 to enhance the strength of the cooling roller body 11.

[0040] Ginseng Figure 4 As shown, the fan blade 14 includes: a fixing ring 141 fixedly arranged on the inner side of the inner roller body 112 and a blade (not shown) arranged in the fixing ring 141 and axially rotating. The fan blade 14 is fixed as a whole through the fixing ring 141, and the fan blade 14 can be configured in multiple numbers and rotate in the same direction, further ensuring the flow speed of the gas in the gas flow channel 91, and then ensuring that the gas can quickly take away the heat absorbed by the cooling water, and once again ensuring the cooling effect of the cooling roller 10 on the fabric.

[0041] To drive the cooling roller 10 to rotate axially, Figure 5 and Figure 6As shown, the cooling roller 10 further includes a first rotary joint 17 and a second rotary joint 18, which are respectively sleeved on the outside of the first hollow shaft 12 and the outside of the second hollow shaft 13. Specifically, the first hollow shaft 12 includes a first hollow connecting segment 121 and a second hollow connecting segment 122, which are connected by the first rotary joint 17. The end of the first hollow connecting segment 121 away from the second hollow connecting segment 122 is detachably assembled to the outside of the first plate 113 via a first locking assembly 15. Therefore, when the cooling roller 10 is driven to rotate axially, the first hollow connecting segment 121 rotates axially with the cooling roller body 11, while the first rotary joint 17 and the second hollow connecting segment 122 remain stationary. Similarly, the second hollow shaft 13 includes a third hollow connecting segment 131 and a fourth hollow connecting segment 132, which are connected via a second rotary joint 18. The end of the third hollow connecting segment 131, distal from the fourth hollow connecting segment 132, is removably attached to the outside of the second plate 114 via a second locking assembly 16. Consequently, when the cooling roller 10 is driven to rotate axially, the third hollow connecting segment 131 rotates axially with the cooling roller body 11, while the second rotary joint 18 and the fourth hollow connecting segment 132 remain stationary. Consequently, the cooling roller 10 is simultaneously driven to rotate axially by a drive assembly (not shown) via the first hollow connecting segment 121 and the third hollow connecting segment 131.

[0042] Based on the technical solutions of the cooling roller 10 disclosed in the aforementioned embodiment, this embodiment further discloses a textile apparatus. The textile apparatus (not shown) includes the cooling roller 10 disclosed in the aforementioned embodiment. The cooling roller 10 can be mounted on a bracket (not shown) at the fabric outlet of a heating box included in the textile apparatus to rapidly cool the heat-treated fabric, thereby fixing its shape and preventing wrinkles or deformation.
