Description

Technical Field

[0001] This utility model belongs to the field of nonwoven fabric processing technology, and more specifically, it relates to a nonwoven fabric embossing equipment. Background Technology

[0002] In the production and processing of nonwoven fabrics, embossing equipment is usually used to perform the embossing process on the nonwoven fabric. In the application of nonwoven fabric embossing equipment, in order to ensure product quality, production continuity and material utilization, operators often need to use their hands to tension and position the end of the nonwoven fabric.

[0003] For example Based on the above, during the process of operators tensioning and positioning the ends of the non-woven fabric with their hands, the inherent individual differences in the stability of the force output and the synchronization of the force application speed of the operators' hands lead to uneven tension at both ends of the non-woven fabric. When the force deviation at both ends of the non-woven fabric exceeds the allowable range of the embossing process, it is very easy to cause the non-woven fabric to shift laterally or wrinkle longitudinally on the worktable of the embossing equipment. This results in appearance defects such as local misalignment, edge defects, or pattern stretching and deformation in subsequent embossing stages, which damages the appearance integrity of the embossed product, increases material consumption, and also affects the product qualification rate. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a nonwoven fabric embossing device. This device solves the problem that during the process of tensioning and positioning the ends of the nonwoven fabric by hand, the inherent individual differences in the stability of the operator's hand strength output and the synchronization of force application speed lead to uneven tension at both ends of the nonwoven fabric. When the force deviation at both ends of the nonwoven fabric exceeds the allowable range of the embossing process, it easily causes lateral displacement or longitudinal wrinkling of the nonwoven fabric on the embossing device's worktable. This results in appearance defects such as local misalignment, edge defects, or pattern stretching deformation in subsequent embossing stages, damaging the appearance integrity of the embossed product, increasing material consumption, and affecting the product qualification rate.

[0008] Furthermore, the positioning auxiliary mechanism also includes: a limiting guide, of which there are two, and the two limiting guides are respectively fixedly connected to the outer side of the top end face of the two drive auxiliary blocks; a limiting guide groove is opened on the inner side of the support auxiliary frame at the alignment position with the limiting guide; the limiting guide on the same side is slidably arranged with the limiting guide groove; an elastic reset member is fixedly connected between the support auxiliary frame and the limiting guide on the same side; and a pressing bracket is fixedly connected to the top end face of the limiting guide.

[0009] Furthermore, a resistance-increasing protrusion is fixedly connected to the bottom end face of the support auxiliary frame; a resistance-increasing groove is provided at the alignment position between the operating worktable and the resistance-increasing protrusion; the resistance-increasing groove on the same side is slidably connected to the resistance-increasing protrusion; and an elastic connector is fixedly connected between the two resistance-increasing protrusions and the operating worktable.

[0011] Compared with the prior art, the present invention has the following beneficial effects: This invention effectively avoids the limitations of manual operation through the coordinated design of a positioning auxiliary mechanism and a tension roller. The positioning auxiliary mechanism enables the positioning and winding of the nonwoven fabric, ensuring uniform force on the nonwoven fabric during the initial stage of conveying. The elastic support below the tension roller can automatically adjust the tension according to the tension changes during the nonwoven fabric conveying process, always maintaining a balanced surface tension of the nonwoven fabric. This effectively avoids appearance defects such as misalignment of embossed patterns, edge defects, or stretching deformation caused by tension deviation, significantly improving the appearance integrity of embossed products, reducing material loss due to defects, and increasing the product qualification rate. This invention significantly simplifies the operation process and improves production continuity and efficiency by combining mechanical structure with automated drive. The positioning auxiliary roller is connected to the drive motor via a connecting shaft. After the clamping block completes the positioning of the non-woven fabric, it can automatically drive the non-woven fabric towards the embossing roller. At the same time, the cooperation between the pressing bracket and the elastic reset component allows the operator to quickly position and release the non-woven fabric with a simple pressing action, without the need for continuous hand support. One person can complete the auxiliary operation of multiple devices, reducing labor costs. In addition, the resistance-increasing protrusion at the bottom of the support auxiliary frame cooperates with the elastic connector to conveniently push the support auxiliary frame towards the embossing roller when the non-woven fabric at the outer end of the positioning auxiliary roller decreases, ensuring that the remaining non-woven fabric is efficiently transferred to the embossing station, avoiding production interruptions caused by untimely manual adjustments, and improving production efficiency. This invention reduces direct contact between operators and hazardous parts through an automated positioning and conveying structure, thereby lowering the probability of workplace accidents. At the same time, the equipment operation process is simplified, requiring only simple actions such as pressing and pushing to complete the positioning of non-woven fabric and equipment adjustment, further improving the flexibility and ease of use of this equipment in practical applications.

[0019] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0020] Example 1: As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a non-woven fabric embossing device, including an operating workbench 1, an embossing device body 2, an embossing roller 3, a positioning auxiliary roller 4, a positioning auxiliary mechanism, and a support auxiliary frame 5.

There are multiple elastic extrusion members 404, which are evenly arranged and fixedly connected between the clamping block 403 and the positioning auxiliary roller 4.

[0022] The positioning auxiliary mechanism also includes a drive auxiliary block 405. There are two drive auxiliary blocks 405, which are elastically arranged at the left and right ends of the two clamping blocks 403 respectively. The contact surface between the drive auxiliary block 405 and the clamping block 403 is an inclined block structure.

[0023] The positioning auxiliary mechanism also includes: a limiting guide 406, of which there are two, and the two limiting guides 406 are respectively fixedly connected to the outer side of the top end face of the two driving auxiliary blocks 405; a limiting guide groove 407 is opened on the inner side of the support auxiliary frame 5 at the alignment position with the limiting guide 406; the limiting guide 406 on the same side is slidably arranged with the limiting guide groove 407; an elastic reset member 408 is fixedly connected between the support auxiliary frame 5 on the same side and the limiting guide 406; and a pressing bracket 409 is fixedly connected to the top end face of the limiting guide 406.

[0024] The specific usage and function of this embodiment are as follows: In use, after holding the left and right sides of the end of the non-woven fabric with both hands, the non-woven fabric is inserted into the positioning groove 402. The inside of the wrist is close to the pressing bracket 409, pressing it downwards. As the pressing bracket 409 slides downwards, the drive auxiliary block 405 pushes the two clamping blocks 403 outwards, allowing the non-woven fabric to smoothly pass through the positioning groove 402. After the non-woven fabric passes through the positioning groove 402, when the operator releases the non-woven fabric with both hands, the elastic reset member 408... The clamping block 403 is reset.

During the printing operation of the embossing roller 3 on the nonwoven fabric, the rotation of the embossing roller 3 and the pressing force on the nonwoven fabric cause the positioning auxiliary roller 4 to rotate. The nonwoven fabric on the outside of the positioning auxiliary roller 4 is then orderly conveyed to the direction of the embossing roller 3.

[0028] The specific usage and function of this embodiment are as follows: In use, the end of the nonwoven fabric is passed around the upper end of the tension roller 6 and conveyed to the lower part of the embossing roller 3. During the embossing process of the nonwoven fabric, the elastic support 602 and the tension roller 6 work together to achieve self-tensioning of the nonwoven fabric. The correction auxiliary block 603 effectively avoids the deviation of the nonwoven fabric. As the nonwoven fabric at the outer end of the positioning auxiliary roller 4 gradually decreases, the operator pushes the support auxiliary frame 5 to slide towards the embossing roller 3 to facilitate the embossing of the remaining nonwoven fabric. The resistance-increasing protrusion 501 realizes the limiting guidance when the support auxiliary frame 5 slides, and the elastic connector 502 realizes the timely automatic reset of the support auxiliary frame 5.
