Description

Technical Field

[0001] The utility model relates to the technical field of printing and dyeing equipment, in particular to a spiral 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 chiller rollers typically continuously deliver cooling water. Fabrics contact the roller's surface, where the flowing cooling water rapidly removes heat from the fabric, thereby rapidly cooling the fabric. However, due to design limitations in the existing chiller roller's internal structure, the roller lacks control over the cooling water as it is delivered to the roller, causing it to flow freely within the roller. This results in wasted cooling water resources and poor cooling performance, further impacting the fabric's physical properties.

[0004] It should be noted that the above introduction to the background technology is merely for the purpose of providing a clear and complete description of the technical solutions of this application and facilitating understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that there is a lack of constraints on the flow of cooling water, the cooling water may flow around randomly, and thus there are problems of cooling water resource waste and poor cooling effect.

[0006] To achieve the above objectives, 1. A spiral cooling roller comprising:

[0007] A cooling roller body and a first hollow shaft and a second hollow shaft axially arranged at both ends of the cooling roller body;

[0008] The cooling roller body includes: an outer roller body and an inner roller body that are nested, and there is a certain gap between the outer roller body and the inner roller body, and an axially annular spiral partition is formed in the gap to separate the gap to form a spiral liquid flow channel, and the first hollow shaft and the second hollow shaft are respectively connected to the two ends of the spiral liquid flow channel.

[0009] As a further improvement of the present invention, the cooling roller body further includes: a first plate body and a second plate body respectively arranged at both ends of the outer roller body and the inner roller body to close the end portions of the cooling roller body.

[0010] As a further improvement of the present invention, the cooling roller body also includes: a first liquid guide tube and a second liquid guide tube respectively arranged at the two ends of the inner side of the inner roller body and connected to the spiral liquid flow channel, the first liquid guide tube axially penetrates the first plate body and docks with the first hollow shaft, and the second liquid guide tube axially penetrates the second plate body and docks with the second hollow shaft.

[0011] As a further improvement of the present invention, the first hollow shaft is detachably assembled on the outside of the first plate body through a first locking assembly, and the second hollow shaft is detachably assembled on the outside of the second plate body through a second locking assembly.

[0012] As a further improvement of the present invention, the first locking assembly includes: a first clamping plate sleeved on the outside of the end of the first catheter and a first bearing sleeved on the outside of the end of the first hollow shaft, with a first locking member continuously passing through the first bearing, the first clamping plate and the first plate body;

[0013] The second locking assembly includes: a second clamping plate sleeved on the outside of the second catheter end and a second bearing sleeved on the outside of the second hollow shaft end, and a second locking piece continuously passes through the second bearing, the second clamping plate and the second plate body.

[0014] As a further improvement of the present invention, the first hollow shaft includes: a first hollow connecting section and a second hollow connecting section, wherein the first hollow connecting section and the second hollow connecting section are connected via a first rotary joint;

[0015] The second hollow shaft includes: a third hollow connecting section and a fourth hollow connecting section, and the third hollow connecting section and the fourth hollow connecting section are connected via a second rotary joint.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The spiral cooling roller comprises a cooling roller body and first and second hollow shafts axially disposed at each end of the cooling roller body. The cooling roller body comprises an outer roller body and an inner roller body nested together, separated by a gap. An axially annular, spiral-shaped partition is formed within the gap to separate the gap and form a spiral liquid flow channel. The first and second hollow shafts are respectively connected to the ends of the spiral liquid flow channel. When the fabric is cooled by the spiral cooling roller, the driving assembly drives the spiral cooling roller to rotate axially, and during the rotation, cooling water is transported to the spiral liquid flow channel through the first hollow shaft or the second hollow shaft, and the cooling water in the spiral liquid flow channel is discharged through the second hollow shaft or the first hollow shaft. When the cooling water flows into the spiral liquid flow channel, it flows in sequence along the contour formed by the partition part. The partition part limits the flow trajectory of the cooling water, thereby preventing the liquid from running around in the gap. At the same time, the flow rate of the cooling water in the spiral liquid flow channel is slowed down through the spiral liquid flow channel to ensure that the cooling water can absorb enough heat, thereby not only saving cooling water resources, but also ensuring the cooling effect of the cooling water on the fabric, thereby solving the problem of lack of constraints on the flow of cooling water in the prior art, and the cooling water running around, thereby wasting cooling water resources and poor cooling effect.

However, it should be noted that these embodiments are not limitations of the present invention, and any equivalent transformations or substitutions in functions, methods, or structures made by ordinary technicians in this field based on these embodiments are all within the scope of protection of the present invention.

[0026] 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.

[0027] Please refer to Figures 1 to 5 As shown, the present invention shows a specific embodiment of a spiral cooling roller 10. The spiral 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 spiral cooling roller 10, and the cooling water inside the spiral cooling roller 10 absorbs the heat of the fabric to quickly cool the fabric. It should be noted that the spiral 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 spiral cooling roller 10 according to the different objects processed by the spiral cooling roller 10 and the textile equipment.

[0028] Ginseng Figure 1 As shown, the spiral cooling roller 10 includes a cooling roller body 11 and a first hollow shaft 12 and a second hollow shaft 13 axially disposed at both ends of the cooling roller body 11. The cooling roller body 11 includes an outer roller body 111 and an inner roller body 112 nested together. A gap (not shown) is formed between the outer roller body 111 and the inner roller body 112, and an axially annular spiral partition 14 is formed in the gap to separate the gap to form a spiral liquid flow channel 91. The first hollow shaft 12 and the second hollow shaft 13 are respectively connected to the two ends of the spiral liquid flow channel 91.

[0029] When the fabric is cooled by the spiral cooling roller 10, the spiral cooling roller 10 is driven by a driving assembly (not shown) to rotate axially, and during the rotation, cooling water is transported to the spiral liquid flow channel 91 through the first hollow shaft 12 or the second hollow shaft 13, and the cooling water in the spiral liquid flow channel 91 is discharged through the second hollow shaft 13 or the first hollow shaft 12. When the cooling water flows into the spiral liquid flow channel 91, it flows in sequence along the contour formed by the partition 14. The partition 14 limits the flow trajectory of the cooling water, thereby preventing the liquid from running around in the gap. At the same time, the spiral liquid flow channel 91 slows down the flow rate of the cooling water in the spiral liquid flow channel 91 to ensure that the cooling water can absorb enough heat, thereby not only saving cooling water resources, but also ensuring the cooling effect of the cooling water on the fabric, thereby solving the problem of lack of constraints on the flow of cooling water in the prior art, and the cooling water running around, thereby wasting cooling water resources and poor cooling effect.

[0030] It should be noted that in the present application, cooling water can be delivered to the spiral liquid flow channel 91 through the first hollow shaft 12, and the cooling water in the spiral liquid flow channel 91 can be discharged through the second hollow shaft 13. Alternatively, cooling water can be delivered to the spiral liquid flow channel 91 through the second hollow shaft 13, and the cooling water in the spiral liquid flow channel 91 can be discharged through the first hollow shaft 12. This embodiment does not specifically limit this, and in the following description, the first hollow shaft 12 delivers cooling water and the second hollow shaft 13 outputs cooling water as an example. At the same time, a drain port 191 for discharging sewage from the cooling roller body 11 is provided on the side of the cooling roller body 11, and a movable plug 192 for movable closing the drain port 191 is provided at the drain port 191. When the sewage in the cooling roller body 11 needs to be discharged, the drain port 191 is opened by the movable plug 192 to discharge the sewage.

[0031] Ginseng Figure 1 As shown, the cooling roller body 11 further includes: a first plate body 113 and a second plate body 114, respectively provided 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. This facilitates the assembly of the first hollow shaft 12 and the second hollow shaft 13 and enhances the strength of the entire cooling roller body 11. Regarding the assembly method of the first hollow shaft 12 and the second hollow shaft 13, the first hollow shaft 12 is detachably assembled to the outside of the first plate body 113 via a first locking assembly 16, and the second hollow shaft 13 is detachably assembled to the outside of the second plate body 114 via a second locking assembly 17. This facilitates the replacement or regular maintenance of the first hollow shaft 12 and / or the second hollow shaft 13.

[0032] 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 spiral liquid flow channel 91. 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 16 includes: a first clamping plate 161 sleeved on the outside of the end of the first liquid guide tube 116 and a first bearing 162 sleeved on the outside of the end of the first hollow shaft 12. A first locking member (not shown) continuously penetrates the first bearing 162, the first clamping plate 161, and the first plate body 113 to enable the first hollow shaft 12 to be detachably assembled to the outside of the first plate body 113. The second locking assembly 17 includes: a second clamping plate 171 sleeved on the outside of the end of the second liquid guide tube 117 and a second bearing 172 sleeved on the outside of the end of the second hollow shaft 13. A second locking member (not shown) continuously penetrates the second bearing 172, the second clamping plate 171 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.

[0033] 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 spiral liquid flow channel 91 formed between the outer roller body 111 and the inner roller body 112 through the first liquid guide tube 116, and then discharges the spiral liquid flow channel 91 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 spiral liquid flow channel 91.

[0034] Ginseng Figure 4 and Figure 5As shown, in order to drive the spiral cooling roller 10 to rotate axially, the spiral cooling roller 10 further includes: a first rotary joint 18 and a second rotary joint 19, 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 section 121 and a second hollow connecting section 122. The first hollow connecting section 121 and the second hollow connecting section 122 are connected by the first rotary joint 18. The end of the first hollow connecting section 121 away from the second hollow connecting section 122 is detachably assembled to the outside of the first plate body 113 via the first locking assembly 16. Therefore, when the spiral cooling roller 10 is driven to rotate axially, the first hollow connecting section 121 rotates axially with the cooling roller body 11, while the first rotary joint 18 and the second hollow connecting section 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 by a second rotary joint 19. The end of the third hollow connecting segment 131 away from the fourth hollow connecting segment 132 is detachably mounted on the outside of the second plate 114 via a second locking assembly 17. The second rotary joint 19 is disposed outside the junction between the third hollow connecting segment 131 and the fourth hollow connecting segment 132. Therefore, when the spiral 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 19 and the fourth hollow connecting segment 132 remain stationary. Based on this, the spiral cooling roller 10 is simultaneously driven to rotate axially by a drive assembly (not shown) through the first hollow connecting segment 121 and the third hollow connecting segment 131.

The textile apparatus (not shown) includes the spiral cooling roller 10 disclosed in the aforementioned embodiment. The spiral 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.
