Description

Technical Field

[0001] This utility model belongs to the technical field of textile and garment processing equipment, specifically a high-efficiency equidistant processing device for elastic fabric in raincoat cuffs. Background Technology

[0002] In the production of raincoats, the processing quality of the elastic fabric in the cuffs directly affects the comfort and aesthetics of the product. Currently, some manual or semi-automatic elastic fabric processing equipment has appeared on the market, but these devices often struggle to achieve efficient and equidistant processing operations in practical applications. In addition, adjusting the processing parameters of these devices usually requires a lot of time and labor costs.

[0003] Application No.: CN201820394163.6. This utility model discloses a high-efficiency equidistant processing device for elastic fabric in raincoat cuffs, belonging to the field of raincoat production technology. It includes a sewing machine body mounted on a table, with a connecting rod positioned between the sewing machine body and the table surface. One end of the connecting rod has a lower roller, and a support rod is mounted on one side of the lower roller, with an upper roller mounted on the support rod. The other end of the connecting rod has the same configuration. The purpose of this utility model is to address the above-mentioned problems by providing a high-efficiency equidistant processing device for elastic fabric in raincoat cuffs. This device is used for processing elastic fabric in cuffs, is highly efficient and labor-saving, and can process multiple cuffs in one pass, ensuring even material distribution and improving product quality.

[0004] For example, existing elastic fabric processing devices typically include a base, a fixed support, and an adjustment mechanism. A drive assembly is mounted on the base, the fixed support supports the material to be processed, and the adjustment mechanism is connected to a clamping assembly via a screw. While this structure can complete basic elastic fabric processing tasks, its processing efficiency and accuracy are easily affected by human factors in actual use; this situation demonstrates the shortcomings of existing technologies.

[0005] Therefore, we have made improvements and proposed a high-efficiency equidistant processing device for the elastic fabric of raincoat cuffs. Utility Model Content

[0006] The purpose of this invention is to solve the problems of low efficiency, difficulty in guaranteeing processing accuracy, and time-consuming and labor-intensive parameter adjustment in current raincoat cuff elastic fabric processing equipment.

[0007] To achieve the above-mentioned objectives and improve the above-mentioned problems, this utility model provides a high-efficiency equidistant processing device for elastic fabric in raincoat cuffs, including a processing main structure. The processing main structure includes a positioning component and an adjustment component. The top of the positioning component is provided with a fixing component, and the adjustment component is located on one side of the positioning component. The high-efficiency equidistant processing of elastic fabric is completed through the coordinated action of the positioning component and the adjustment component. Guide components are provided on both sides of the positioning component, and a sliding unit is provided inside the guide component.

[0008] The adjustment assembly includes a drive shaft, and a plurality of limiting blocks are fixedly provided on the circumference of the drive shaft. A pressing strip is provided between each of the plurality of limiting blocks. The outer surface of the pressing strip is provided with a friction layer. The positioning assembly includes two positioning wheels located on both sides of the drive shaft. When the positioning wheels roll on the surface of the elastic cloth, the pressing strip performs an intermittent pressing operation on the elastic cloth to be processed.

[0009] As a preferred technical solution of this application, the fixing member includes a support plate, and the top of the support plate has two mounting holes communicating with the bottom of the support plate, and the two positioning wheels are respectively located inside the two mounting holes.

[0010] As a preferred technical solution of this application, the positioning component further includes two second brackets welded and fixed to the bottom end of the support plate, two positioning wheels are respectively rotatably connected to opposite sides of the two second brackets, the transmission shaft is rotatably connected between the two second brackets, and a first bracket fixedly connected to the support plate is rotatably provided on opposite sides of the two positioning wheels.

[0011] As a preferred technical solution of this application, the guide includes a guide rail, which is used to connect with the sliding unit.

[0012] As a preferred technical solution of this application, the sliding unit includes a slider that is slidably connected inside the guide rail, and the slider is fixedly connected to the support plate.

[0013] As a preferred technical solution of this application, an elastic pad is fixedly provided on the circumferential side of the positioning wheel.

[0014] As a preferred technical solution of this application, a return spring is fixedly provided inside the guide rail, and the end of the return spring is welded and fixed to the slider.

[0015] As a preferred technical solution of this application, the top of the support plate is provided with a through groove communicating with the bottom of the support plate, and the through groove is located between two mounting holes.

[0016] Compared with existing technologies, the advantages of this invention are as follows: By incorporating an adjustment and positioning component, the positioning component guides and initially fixes the elastic fabric during processing. Subsequently, the transmission shaft in the adjustment component drives the limiting blocks and pressing strips to perform intermittent pressing operations on the elastic fabric, thus forming equidistant processing areas. In this process, the elastic pad of the positioning wheel effectively reduces the slippage and offset of the elastic fabric during processing, while the return spring ensures stable movement of the slider within the guide rail, further improving processing accuracy. Furthermore, by adjusting the spacing between the limiting blocks, it can flexibly adapt to the processing needs of elastic fabrics of different specifications, solving the problems of low efficiency, insufficient accuracy, and cumbersome parameter adjustments in existing elastic fabric processing equipment.

[0017] The following is a detailed description:

[0018] The positioning assembly's core component is the positioning wheel, which is fixed to the support plate via mounting holes and stably connected by brackets one and two. An elastic pad, made of rubber, is located on the circumference of the positioning wheel. This pad provides appropriate clamping force when the slack cloth passes through, preventing it from shifting or slipping during processing. Bearings connect the positioning wheel to bracket two on both sides, ensuring free rotation and adapting to the direction of movement of the slack cloth.

[0019] The core component of the adjusting assembly is the drive shaft, which is connected to the second bracket at both ends via bearings to ensure smooth rotation. Limit blocks are fixed to the circumference of the drive shaft, and the spacing between the limit blocks can be adjusted according to actual processing requirements. A clamping strip is installed between the limit blocks, and its outer surface is covered with a friction layer made of a high-friction coefficient material. This friction layer provides sufficient friction when clamping the elastic cloth, preventing slippage during processing.

[0020] The guide component and sliding unit work together. The guide component is in the form of a guide rail, and a sliding unit is installed inside. The sliding unit includes a slider and a return spring. The slider is fixedly connected to the support plate by bolts. When the elastic cloth is subjected to external force during processing, the slider can slide in the guide rail in a set direction. At the same time, the elastic force of the return spring can make the slider quickly return to the initial position after the force is removed, thereby ensuring the stability of the positioning component.

[0021] The fastener is designed and installed as a support plate with two mounting holes and a through slot at its top. The mounting holes are used to fix the positioning wheels, while the through slot reduces the overall weight of the support plate and facilitates observation of the processing status of the elastic fabric. The bottom of the support plate is welded to brackets one and two to ensure the overall structural stability.

[0022] The working mechanism of the elastic pad and friction layer: The design of the elastic pad and friction layer aims to improve the stability and precision of the processing. The elastic pad can absorb the vibration and impact generated by the elastic cloth during processing, reducing the displacement of the elastic cloth caused by external forces; the friction layer, by increasing the friction of the contact surface, ensures that the clamping strip can firmly fix the elastic cloth, thereby forming a uniform and equidistant processing area.

[0023] The spacing between the limit blocks can be adjusted manually or automatically. For manual adjustment, the user can loosen the fixing bolts on the limit block, move it axially along the drive shaft to the desired position, and then re-fix it. For automatic adjustment, the drive shaft is rotated by a motor, and the threaded structure on the limit block achieves automatic positioning. These adjustment methods can quickly adapt to the processing needs of elastic fabrics of different specifications, significantly improving the flexibility and applicability of the equipment.

[0024] In actual use, the overall structure's workflow involves the elastic fabric first being initially fixed and guided by the positioning wheels in the positioning assembly, and then entering the processing area of ​​the adjustment assembly. As the drive shaft rotates, the limit blocks and clamping strips move accordingly, performing interval clamping operations on the elastic fabric to form equidistant processing areas. After processing, the elastic fabric is output from the other side of the positioning wheels; the entire process is efficient and precise.

[0025] Through the above technical solution, this utility model successfully solves the problems of low efficiency, insufficient precision and cumbersome parameter adjustment in the existing elastic fabric processing equipment, and provides reliable technical support for the efficient and equidistant processing of elastic fabric for raincoat cuffs.

[0031] This utility model relates to a high-efficiency equidistant processing device for elastic fabric in raincoat cuffs, the structure of which is as follows: Figures 1 to 4 As shown in the accompanying drawings, the specific embodiments of this utility model will be described in detail below.

[0032] The main processing structure 1 includes a positioning component 2 and an adjusting component 3, which work together to achieve efficient equidistant processing of the elastic fabric. The top of the positioning component 2 is equipped with a fixing member 4, which includes a support plate 11. The support plate 11 is a rectangular flat plate with two mounting holes 12 at its top that communicate with the bottom. Two positioning wheels 10 are fixed to the support plate 11 through the mounting holes 12. Elastic pads 18, made of rubber, are provided on the circumferential side of the positioning wheels 10. These elastic pads are uniform in thickness and tightly adhere to the outer surface of the positioning wheels 10. Two secondary brackets 13 are welded to the bottom of the support plate 11. The secondary brackets 13 are L-shaped metal parts; their vertical parts are welded and fixed to the bottom of the support plate 11, and their horizontal parts, facing the positioning wheels 10, have bearing seats for mounting the rotating shafts of the positioning wheels 10. The positioning wheels 10 are rotatably connected to the secondary brackets 13 via bearings, ensuring their free rotation. In addition, a first bracket 14 is provided on both sides of the positioning wheel 10. The first bracket 14 is a U-shaped metal part, with its two ends welded and fixed to the support plate 11 respectively, and the middle part connected to the rotating shaft of the positioning wheel 10 through a bearing, which further enhances the stability of the positioning wheel 10.

[0033] The adjusting component 3 is located on one side of the positioning component 2 and includes a drive shaft 7. Both ends of the drive shaft 7 are rotatably connected to the horizontal portions of two secondary brackets 13 via bearings. Several limiting blocks 8 are fixedly provided on the circumferential side of the drive shaft 7. The limiting blocks 8 are evenly distributed along the axial direction of the drive shaft 7, and each limiting block 8 is fixed to the drive shaft 7 by bolts. A clamping strip 9 is provided between the limiting blocks 8. The clamping strip 9 is a long strip of metal, and its outer surface is covered with a friction layer 20. The friction layer 20 is made of a material with a high coefficient of friction, and its thickness is uniform and tightly adheres to the outer surface of the clamping strip 9. The number and spacing of the limiting blocks 8 can be adjusted according to actual processing requirements to adapt to the processing requirements of different specifications of elastic fabric.

[0034] Guide components 5 are located on both sides of the positioning assembly 2, including guide rails 15. Guide rails 15 are rectangular groove structures with sliding units 6 inside. Sliding units 6 include sliders 16 and return springs 17. Slider 16 is a rectangular metal block whose dimensions match the inner cavity of the guide rail 15. Slider 16 is fixedly connected to the support plate 11 by bolts. Return spring 17 is located inside the guide rail 15, with one end welded to the inner wall of the guide rail 15 and the other end welded to the slider 16, ensuring that slider 16 can slide along a set direction within the guide rail 15 and quickly return to its initial position after the force is removed.

[0035] A through groove 19 is also provided at the top of the support plate 11. The through groove 19 is located between the two mounting holes 12. It is used to reduce the overall weight of the support plate 11 and facilitate the observation of the processing status of the elastic fabric. The width and length of the through groove 19 are designed according to actual needs to ensure that the strength of the support plate 11 is not affected.

[0036] In actual use, the elastic cloth is first initially fixed and guided by the positioning wheels 10 in the positioning assembly 2. The elastic cloth enters between the positioning wheels 10 from one side. Because the positioning wheels 10 have elastic pads 18 on their circumferential sides, the elastic cloth is subjected to a certain clamping force when passing through, preventing it from shifting or slipping. The positioning wheels 10 are connected to the second bracket 13 and the first bracket 14 through bearings, ensuring that they can rotate freely and adapt to the movement direction of the elastic cloth. Subsequently, the elastic cloth enters the processing area of ​​the adjusting assembly 3. The drive shaft 7 rotates under the drive of the motor, driving the limiting blocks 8 and the pressing strip 9 to move accordingly. The distance between the limiting blocks 8 determines the width of the area where the elastic cloth is pressed, while the outer surface of the pressing strip 9 is covered with a friction layer 20, which can provide sufficient friction when pressing the elastic cloth to prevent the elastic cloth from slipping during processing.

[0037] When the elastic fabric is subjected to external force during processing, the slider 16 can slide along the set direction within the guide rail 15. Simultaneously, the elastic force of the return spring 17 causes the slider 16 to quickly return to its initial position after the force disappears, thus ensuring the stability of the positioning component 2. Furthermore, the spacing between the limit blocks 8 can be adjusted manually or automatically. For manual adjustment, the user can loosen the fixing bolts on the limit blocks 8, move them axially along the drive shaft 7 to the desired position, and then re-fix them. For automatic adjustment, the drive shaft 7 can be rotated by a motor, and automatic positioning is achieved using the threaded structure on the limit blocks 8. These adjustment methods can quickly adapt to the processing needs of elastic fabrics of different specifications, significantly improving the flexibility and applicability of the equipment.

[0038] After processing, the elastic fabric is output from the other side of the positioning wheel 10, making the entire process efficient and precise. Through the above structural design, this utility model successfully achieves efficient equidistant processing of elastic fabric, solving the problems of low efficiency, insufficient precision, and cumbersome parameter adjustment in existing elastic fabric processing equipment.

[0039] The various components of this invention, through reasonable structural design and connection relationships, ensure the stability and reliability of the device. For example, the positioning wheel 10 reduces the slippage and offset of the elastic fabric through the elastic pad 18, the return spring 17 ensures the stable movement of the slider 16 through its elastic force, and the limiting block 8 and the pressing strip 9 provide sufficient friction through the friction layer 20, thereby forming a uniform equidistant processing area. The overall structural design fully considers the needs of actual application scenarios and can meet the processing requirements of elastic fabrics of different specifications, providing reliable technical support for the efficient equidistant processing of elastic fabrics for raincoat cuffs. To better enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention is further explained below in conjunction with a specific application scenario.

[0040] In actual operation, the elastic cloth to be processed is first placed between the two positioning wheels 10 in the positioning assembly 2. The positioning wheels 10 apply a certain clamping force to the elastic cloth through the elastic pad 18, which is made of rubber material and has good elasticity and friction properties. When the elastic cloth enters between the positioning wheels 10, the elastic pad 18 contacts the surface of the elastic cloth and uses the reaction force generated by its elastic deformation to form a stable clamping effect on the elastic cloth, thereby preventing the elastic cloth from shifting or slipping during movement. At the same time, the positioning wheels 10 are connected to the second bracket 13 and the first bracket 14 through bearings to ensure that they can rotate freely to adapt to the movement direction of the elastic cloth and reduce the resistance caused by friction.

[0041] Subsequently, the elastic cloth is guided to the processing area of ​​the adjusting component 3. Driven by a motor, the drive shaft 7 rotates, causing the limiting blocks 8 and the pressing strip 9 fixed to its circumference to move synchronously. The spacing between the limiting blocks 8 determines the width of the area where the elastic cloth is pressed, while the friction layer 20 covering the outer surface of the pressing strip 9 further enhances the fixing effect on the elastic cloth. The friction layer 20 is made of a high-friction coefficient material, providing sufficient friction when the pressing strip 9 contacts the elastic cloth, preventing the elastic cloth from slipping during processing. Through this structural design, the elastic cloth remains stable throughout the processing, thus ensuring the accuracy of equidistant processing.

[0042] When the elastic cloth is subjected to external force during processing, the slider 16 in the sliding unit 6 slides along the inner cavity of the guide rail 15. The slider 16 is fixedly connected to the support plate 11 by bolts, and its size matches the inner cavity of the guide rail 15 to ensure smooth and stable sliding. The return spring 17 is located inside the guide rail 15, with one end welded to the inner wall of the guide rail 15 and the other end welded to the slider 16. After the external force disappears, the elastic force of the return spring 17 causes the slider 16 to quickly return to its initial position, thereby ensuring the stability of the positioning assembly 2. In addition, the rectangular groove structure of the guide rail 15 provides precise guidance for the slider 16, further improving the overall stability of the device.

[0043] During processing, if it is necessary to adjust the spacing between the limit blocks 8 to accommodate the processing requirements of elastic fabrics of different specifications, this can be achieved manually or automatically. For manual adjustment, the user needs to loosen the fixing bolts on the limit blocks 8, move them axially along the drive shaft 7 to the desired position, and then re-fix them. For automated adjustment, the drive shaft 7 can be rotated by a motor, and automatic positioning can be achieved using the threaded structure on the limit blocks 8. These adjustment methods eliminate the need for complex operating procedures, significantly improving the flexibility and applicability of the equipment.

[0044] After processing, the elastic cloth is output from the other side of the positioning wheel 10. Throughout the processing, the design of the through groove 19 not only reduces the overall weight of the support plate 11, but also facilitates the operator to observe the processing status of the elastic cloth in real time. The through groove 19 is located between the two mounting holes 12, and its width and length are reasonably designed to ensure that the strength of the support plate 11 is not affected, while meeting the actual use requirements.

[0045] Through the above structural design and operating principle, this utility model successfully achieves efficient equidistant processing of elastic fabric. The elastic pad 18 of the positioning wheel 10 effectively reduces the slippage and offset of the elastic fabric during processing, the return spring 17 ensures the stable movement of the slider 16, and the limiting block 8 and the pressing strip 9 provide sufficient friction through the friction layer 20, thereby forming a uniform equidistant processing area. The overall structural design fully considers the needs of actual application scenarios and can meet the processing requirements of elastic fabrics of different specifications, providing reliable technical support for efficient equidistant processing of elastic fabric for raincoat cuffs.

[0046] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
