Description

Technical Field

[0001] This utility model relates to the field of textile fabric conveying, and specifically to a textile fabric conveying device. Background Technology

[0002] Textile fabrics are woven using different weaving methods such as weft knitting and warp knitting. Throughout the production process, textile fabrics undergo several processes guided by guide rollers, including spraying, printing, ironing, and inspection. During the conveying process, wrinkles often appear on the fabric surface, necessitating smoothing during transport.

[0003] In existing technologies, a common method for achieving fabric leveling is to install arc-shaped rollers along the fabric conveying path, with the apex of the arc located in the middle. When the fabric passes over the arc-shaped rollers, the tension of the fabric itself, combined with the inclined structure on both sides of the rollers, helps to eliminate wrinkles on the fabric surface. Examples include: Solution 1, Chinese Invention Patent No. 202411735655.3, filed November 29, 2024, entitled "A Textile Fabric Conveying Device"; and Solution 2, Chinese Utility Model Patent No. 202021956746.7, filed September 9, 2020, entitled "A Conveying Device for Processing Polyester Fabric with a Fixing Function". Solution 3, application number 202321613697.0, application date: June 25, 2023, the technical solution recorded in the Chinese utility model patent entitled "An unwinding mechanism and unwinding assembly".

[0004] However, the applicant of this application has found the following shortcomings in the existing technology, including the aforementioned technical solutions, when using curved rollers to level fabrics: Through experiments, the applicant discovered that for different textile fabrics, due to their weaving processes and raw materials, the contact position between the textile fabric and the curved structure of the curved roller surface varies when passing through it, often resulting in deviations in the leveling effect. Furthermore, the curved structure of the curved rollers in the existing technology is fixed, making it difficult to achieve an ideal leveling effect when leveling different fabrics. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a textile fabric conveying device with an adjustment mechanism at one end of the arc roller. The adjustment mechanism can drive the arc roller to rotate according to the characteristics of the fabric, so as to change the contact position between the fabric and the arc roller, so as to ensure that the arc roller can form the best flattening effect on the fabric and avoid wrinkles during the fabric conveying process.

[0006] The technical solution adopted by this utility model to solve its technical problem is: the textile fabric conveying device includes a guide roller group for guiding the fabric and an arc roller. The arc roller includes a mandrel and an outer cylinder fitted outside the mandrel. The feature is that: one end of the mandrel is an adjusting end and the other end is a free end. An adjusting mechanism is provided at the adjusting end of the mandrel. The adjusting end of the mandrel is coaxially fixed with the rotating shaft of the adjusting mechanism.

[0007] Preferably, a vertically arranged mounting surface is provided, and two fixed seats are arranged side by side on the surface of the mounting surface. The guide roller group and the arc-shaped roller are installed between the two fixed seats.

[0008] Preferably, the guide roller assembly includes a set of vertically arranged outer guide rollers and an inner guide roller, with the inner guide roller located inside the outer guide rollers. The outer guide rollers are located at the front end face of the fixed base, and the inner guide rollers are located on the opposite surfaces of the two fixed bases.

[0009] Preferably, the adjusting mechanism is a worm gear mechanism, which is installed at the bottom of one of the fixed seats and a bearing seat is installed at the bottom of the other fixed seat. One end of the spindle is coaxially fixed with the axle of the worm wheel in the worm gear mechanism, and the other end of the spindle is inserted into the bearing seat.

[0010] Preferably, the mandrel is an arc-shaped shaft, including an arc-shaped section in the middle and horizontal sections at both ends of the arc-shaped section. One horizontal section is coaxially fixed with the axle of the worm wheel in the worm gear mechanism, and the other horizontal section is rotatably connected to the bearing seat.

[0011] Preferably, a handwheel is provided, which is coaxially fixed with the worm in the worm gear mechanism.

[0012] Preferably, a fixing frame is provided at the lower part of the guide roller group and the arc roller, and a cloth roller is installed in the fixing frame, with the cloth wrapped around the cloth roller.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In the textile fabric conveying device of this application, an adjustment mechanism is provided at one end of the arc-shaped roller. The arc-shaped roller can be rotated by the adjustment mechanism according to the characteristics of the fabric to change the contact position between the fabric and the arc-shaped roller, so as to ensure that the arc-shaped roller can form the best flattening effect on the fabric and avoid wrinkles during the fabric conveying process.

[0015] The adjustment mechanism utilizes a worm gear mechanism, which leverages the self-locking characteristic of the worm gear and worm after meshing to effectively prevent the arc-shaped shaft from rotating during fabric transmission. Attached Figure Description

[0021] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0022] like Figures 1-2 As shown, a textile fabric conveying device includes a mounting surface 1, which is perpendicular to a horizontal plane (such as the ground). The mounting surface 1 can be a plate or frame erected on a horizontal plane, or it can be the end face of the equipment.

[0023] On the upper part of the mounting surface 1, two fixed seats 3 are spaced apart, and guide roller assemblies are mounted on the two fixed seats 3. The guide roller assembly includes an outer guide roller 2 mounted on the front end face of the fixed seat 3 and an inner guide roller 13 mounted on the opposite faces of the two fixed seats 3. Several bearing seats 4 are provided on the fixed seats 3, corresponding to the outer guide roller 2 and the inner guide roller 13 respectively. The two ends of the outer guide roller 2 and the inner guide roller 13 are respectively mounted in the corresponding bearing seats 4 to realize the rotational connection between the outer guide roller 2 and the inner guide roller 13.

[0024] The arrangement and number of the outer guide rollers 2 and the inner guide rollers 13 can be determined according to the direction of the fabric 11 during transmission. In the textile fabric conveying device of this application, two outer guide rollers 2 are arranged vertically, and one inner guide roller 13 is arranged inside the two outer guide rollers 2.

[0025] A mounting plate 5 is attached to the bottom of one of the fixed seats 3. A worm gear mechanism 6 is mounted on the bottom surface of the mounting plate 5. A bearing seat 4 corresponding to the worm gear mechanism 6 is mounted on the bottom of the other fixed seat 3. An arc-shaped roller 10 is installed between the worm gear mechanism 6 and the bearing seat 4.

[0026] Combination Figure 3The arc-shaped roller 10 includes a mandrel 15 and an outer cylinder 14 fitted outside the mandrel 15. The mandrel 15 is a rigid shaft, including an arc-shaped section and horizontal sections fixed at both ends of the arc-shaped section. The outer cylinder 14 is a flexible cylindrical component, fitted outside the arc-shaped section of the mandrel 15.

[0027] One horizontal section at each end of the arc-shaped segment of the mandrel 15 is inserted into the bearing seat 4, and the other horizontal section of the mandrel 15 is coaxially fixed with the worm gear in the worm gear mechanism 6. A handwheel 7 is coaxially fixed at the end of the worm in the worm gear mechanism 6. There is relative rotation between the outer cylinder 14 and the mandrel 15, and both ends of the outer cylinder 14 extend to the bearing seat 4 and the worm gear mechanism 6, respectively. The arrangement of the outer cylinder 14 and the mandrel 15 is common knowledge and common practice in the field (such as the technical solution described in Chinese Utility Model Patent Application No. 202321613697.0, filed on June 25, 2023, entitled "An Unwinding Mechanism and Unwinding Assembly"), and will not be described in detail here.

[0028] A fixing frame 9 is provided at the lower part of the fixing base 3. The end of the horizontal section of the fixing frame 9 is fixed to the mounting surface 1 by a fixing plate 8, and the vertical section of the fixing frame 9 is fixed to the horizontal surface. A cloth roller 12 is horizontally provided in the middle of the fixing frame 9, and cloth 11 is wound on the cloth roller 12.

[0029] The specific working process and working principle are as follows:

[0030] like Figure 4 As shown, after the fabric 11 is released from the fabric roller 12, it is conveyed sequentially by passing over the arc roller 10, the inner guide roller 13, and the outer guide roller 2. During the conveying process, the fabric 11 causes the outer cylinder 14 and the mandrel 15 to rotate relative to each other due to the friction between the fabric 11 and the outer cylinder 14.

[0031] Since one end of the mandrel 15 is coaxially fixed with the worm in the worm gear mechanism 6, the worm is always stationary due to the self-locking characteristic of the worm gear reduction mechanism, which prevents the fabric 11 from causing the mandrel 15 to rotate during the conveying process.

[0032] When it is necessary to adjust the direction of the arc roller 10 according to the characteristics of the fabric 11, the worm in the worm gear mechanism 6 is rotated by turning the handwheel 7, which in turn drives the spindle 15 to rotate, thereby adjusting the position of the arc top of the arc roller 10. This ensures that the arc roller 10 can achieve the best flattening effect on the fabric 11 and avoids wrinkles during the conveying process of the fabric 11.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
