Description

Technical Field

[0001] This utility model relates to the field of double-sided seam equipment technology, and in particular to an automatic double-sided seam cutting device. Background Technology

[0002] In the existing technology, the production and manufacturing of carpets and curtains usually involves cutting rolls of fabric into pieces and binding the edges with existing sewing equipment. In order to improve production efficiency, factories usually first use double-sided sewing equipment to continuously sew the two sides of the roll of fabric, and then manually cut the fabric according to the preset size and sew the cut edges with sewing equipment to complete the production.

[0003] However, after the front-end double-sided sewing equipment achieves continuous operation, subsequent cutting relies on manual labor to cut according to preset dimensions. This is not only inefficient and the dimensional accuracy is easily affected by the operator's experience, but it also cannot match the continuous output speed of the front-end, resulting in a backlog of production capacity. The lack of automated connection equipment and manual transfer further consume time, ultimately making it difficult to improve equipment utilization, personnel efficiency and overall production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic double-sided seam cutting system, which aims to at least solve the technical problem in the prior art where, after the double-sided seam cutting equipment achieves continuous operation, subsequent seam cutting relies on manual cutting, resulting in difficulty in improving the overall production efficiency.

[0005] To achieve the above objectives, the present invention provides an automatic double-sided seam cutting method, comprising:

[0006] A frame is provided with a fabric cutting mechanism, a fabric feeding mechanism and a sewing mechanism. The fabric cutting mechanism includes a moving component and a cutting component to move and cut the fabric onto the fabric feeding mechanism. The sewing mechanism includes a first sewing head and a second sewing head, which are arranged at a left-right interval.

[0007] The conveying path of the fabric feeding mechanism is approximately perpendicular to the moving path of the moving component, and the conveying path of the fabric feeding mechanism is approximately parallel to the cutting path of the cutting component, so as to form a first cutting edge and a second cutting edge on the left and right sides of the fabric to be cut, respectively. When the fabric feeding mechanism conveys the fabric to be cut toward the sewing mechanism, the first cutting edge is sewn by the first sewing head, and the second sewing head is sewn by the second sewing head.

[0008] Furthermore, the first machine head is slidably mounted on the frame in the left-right direction;

[0009] And / or, the second head is slidably mounted on the frame in the left-right direction so that the distance between the first head and the second head is adjustable.

[0010] Furthermore, a support member is provided between the first machine head and the second machine head.

[0011] Furthermore, the support member is slidably mounted on the frame in the left-right direction.

[0012] Furthermore, the support member includes at least one roller member.

[0013] Furthermore, the moving component includes a gripper structure that is slidably mounted on the frame in the left-right direction to grip the fabric on the side close to the second cut edge and slide it to move the fabric above the feeding mechanism.

[0014] Furthermore, the cutting component includes:

[0015] A clamping assembly, mounted on the frame, is used to secure the fabric away from the second cut edge.

[0016] A cutting machine, which is slidably mounted on the frame in the front-to-back direction to cut a first cut edge of the fabric.

[0017] Furthermore, a plurality of rollers are provided on the frame and on the side of the fabric cutting mechanism away from the fabric feeding mechanism. The length of the plurality of rollers extends in the front-back direction so as to taut the fabric by wrapping the fabric around and inserting it between adjacent rollers.

[0018] Furthermore, the sewing mechanism also includes a first conveyor belt assembly and a second conveyor belt assembly to drive the first cut edge to align and push it into the sewing area of ​​the first sewing head via the first conveyor belt, and to drive the second cut edge to align and push it into the sewing area of ​​the second sewing head via the second conveyor belt.

[0019] Furthermore, the first conveyor belt assembly and / or the second conveyor belt assembly are conveying clamping structures, the conveying clamping structure comprising:

[0020] A lower conveyor belt having a first conveying plane located on one side of the sewing area of ​​the first or second machine head;

[0021] An upper conveyor belt has a second conveying plane. The upper conveyor belt is slidably mounted on the frame. The second conveying plane and the first conveying plane are arranged opposite to each other so that the fabric is clamped by the first conveying plane and the second conveying plane to drive the first cutting edge to align and push into the sewing area of ​​the first machine head or to drive the second cutting edge to align and push into the sewing area of ​​the second machine head.

[0022] As can be seen from the above technical solution, the automatic double-sided seam cutting of this utility model, by setting up a fabric cutting mechanism, a fabric feeding mechanism, and a sewing mechanism, cuts the rolled fabric that has been completed for double-sided seam cutting, and performs a sewing operation on the two cut edges of the cut fabric. The fabric cutting mechanism includes a moving component and a cutting component. The moving component is used to pull the rolled fabric above the fabric feeding mechanism so that after the cutting component cuts the fabric, the fabric can fall onto the fabric feeding mechanism. The fabric feeding mechanism transports the cut fabric to the sewing mechanism, where the two cut edges are sewn together to complete the production process. This setup eliminates the problems of low efficiency and unstable precision of manual cutting in traditional processes, as well as the capacity backlog and time-consuming manual transfer caused by continuous sewing in the previous process and intermittent operation in the subsequent process. It simplifies the production process, reduces operational complexity, improves the consistency of sewing quality, is more suitable for the needs of large-scale production, and comprehensively improves production efficiency and product quality.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] For ease of understanding, in this application, the observer faces the appendix Figure 2 When observing, the left side of the observer is designated as front, the right side as back, the front of the observer as down, the back of the observer as up, the top of the observer as left, and the bottom of the observer as right. It should be noted that the terms "front end", "rear end", "left side", "right side", "middle", "above", "below" etc. in the text indicate the orientation or positional relationship based on the accompanying drawings. They are only for the purpose of clearly describing this utility model and do not indicate or imply that the structure or component referred to must have a specific orientation or be constructed in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] Please refer to the following: Figures 1 to 4This embodiment provides an automatic double-sided seam cutting mechanism, including a frame 100. The frame 100 is equipped with a fabric cutting mechanism 200, a fabric feeding mechanism 300, and a sewing mechanism 400. The fabric cutting mechanism 200 includes a moving component 210 and a cutting component 220, which move and cut the fabric onto the fabric feeding mechanism 300. The sewing mechanism 400 includes a first sewing head 410 and a second sewing head 420, which are spaced apart horizontally. The conveying path of the mechanism 300 is roughly perpendicular to the moving path of the moving component 210, and the conveying path of the fabric feeding mechanism 300 is roughly parallel to the cutting path of the cutting component 220, so as to form a first cutting edge and a second cutting edge on the left and right sides of the fabric to be cut, respectively. When the fabric feeding mechanism 300 conveys the fabric to be cut toward the sewing mechanism 400, the first cutting edge is sewn by the first sewing head 410, and the second sewing head 420 is sewn by the second sewing head 420.

[0039] As can be seen, the automatic double-sided seam cutting in this embodiment, by setting up a fabric cutting mechanism 200, a fabric feeding mechanism 300, and a sewing mechanism 400, cuts the rolled fabric with the double-sided seam completed, and sews the two cut edges of the cut fabric. The fabric cutting mechanism 200 includes a moving component 210 and a cutting component 220. The moving component 210 is used to pull the rolled fabric above the fabric feeding mechanism 300 so that after the cutting component 220 cuts the fabric, the fabric can fall onto the fabric feeding mechanism 300. On the 0th, the fabric feeding mechanism 300 transports the cut fabric to the sewing mechanism 400, where the two cut edges are sewn together to complete the production process. This setup eliminates the problems of low efficiency and unstable precision of manual cutting in traditional processes, as well as the backlog of production capacity and time-consuming manual transfer caused by continuous sewing in the previous process and intermittent operation in the subsequent process. It simplifies the production process, reduces operational complexity, improves the consistency of sewing quality, is more suitable for the needs of large-scale production, and comprehensively improves production efficiency and product quality.

[0040] Preferably, to match the production efficiency of the preceding double-sided seam equipment, multiple automatic double-sided seams can be used to avoid production backlog.

[0041] In this embodiment, the first head 410 is slidably mounted on the frame 100 in the left-right direction and the second head 420 is slidably mounted on the frame 100 in the left-right direction, so that the distance between the first head 410 and the second head 420 is adjustable. The frame 100 includes a first ball linear guide rail extending in the left-right direction, and the first head 410 and the second head 420 are respectively mounted on two different sliding blocks of the first ball linear guide rail.

[0042] By adjusting the distance between the first machine head 410 and the second machine head 420, the equipment can flexibly adapt to fabrics of different lengths and specifications. There is no need to configure special equipment for a single fabric width, which greatly improves operational flexibility, reduces the time cost of equipment adjustment or replacement during production, and effectively expands the applicability of the equipment. One machine can meet the processing needs of multiple fabrics, reducing the equipment procurement and maintenance costs of enterprises, and providing efficient support for large-scale, multi-category double-sided sewing production of fabrics.

[0043] In this embodiment, a support member 500 is provided between the first machine head 410 and the second machine head 420. This arrangement can provide stable support for the fabric portion located between the first machine head 410 and the second machine head 420, preventing the fabric from sagging, wrinkling, or shifting due to its own weight or uneven tension during conveying and sewing. This ensures that the fabric always remains flat, thereby guaranteeing the sewing accuracy and quality of the first and second cut edges. At the same time, it reduces sewing errors caused by fabric shaking, improving overall processing stability and product qualification rate.

[0044] Preferably, the support member 500 is slidably mounted on the frame 100 in the left-right direction. The support member 500 is also slidably mounted on another sliding block of the first ball linear guide rail, allowing the support member 500 to move synchronously with the adjustment of the distance between the first machine head 410 and the second machine head 420. This ensures that the support member 500 is always in a suitable position between the two machine heads, providing stable support for the middle portion of fabrics of different lengths. This avoids problems such as fabric sagging and wrinkling caused by support failure or improper support position due to changes in the distance between the machine heads. Furthermore, it improves the equipment's adaptability to different fabric specifications and ensures the seam precision and stability under various processing dimensions.

[0045] Preferably, the support member 500 includes at least one roller member 510. The roller member 510 includes a fixed bracket and a roller. The roller is rotatably mounted on the top of the fixed bracket. Through the rolling characteristics of the roller member 510, it can provide stable support for the middle part of the fabric to prevent sagging or wrinkles. It can also reduce the frictional resistance between the support structure and the fabric during the fabric conveying process by rolling, avoiding fabric wear or conveying jams caused by relative sliding between the support structure and the fabric. This ensures smooth fabric conveying while protecting the surface quality of the fabric, further improving the stability of the processing process and the yield rate of the product.

[0046] In this embodiment, the moving component 210 includes a gripper structure 211, which is slidably mounted on the frame 100 in the left-right direction. The gripper structure 211 grips the fabric near the second cut edge and slides to move the fabric above the feeding mechanism 300. The gripper structure 211 includes an upper clamping plate, a lower clamping plate, and an electric push rod. The fixed end of the electric push rod is connected to the upper clamping plate, and the telescopic end of the electric push rod is connected to the lower clamping plate, so that the distance between the upper and lower clamping plates can be adjusted by the electric push rod. The frame 100 is also provided with a second ball linear guide rail, which extends in the left-right direction. The upper clamping plate is connected to the slider of the second ball linear guide rail, so that the upper and lower clamping plates can grip the fabric near the second cut edge and slide to move the fabric above the feeding mechanism 300. The first and second ball linear guides are existing ball linear guides, which are not the focus of this solution, so they will not be elaborated on here.

[0047] The clamping structure 211 precisely holds the fabric near the second cutting edge, and during the sliding process, it stably moves the fabric above the feeding mechanism 300. This not only ensures the positional accuracy of the fabric during the transfer process and avoids deviations in subsequent cutting and sewing due to displacement, but also enables efficient fabric transfer through directional sliding, reducing manual intervention and improving automation. At the same time, the precise clamping of the second cutting edge lays the positional foundation for the subsequent sewing process, further ensuring the overall accuracy and efficiency of double-sided sewing.

[0048] In this embodiment, the cutting assembly 220 includes a pressing assembly 221 and a cutting machine 222. The pressing assembly 221 is mounted on the frame 100 to fix the fabric away from the second cutting edge. The frame 100 is provided with a pressing table. The pressing assembly 221 includes a pressing member and an electric push rod. The pressing member is connected to the telescopic end of the electric push rod, and the fixed end of the electric push rod is connected to the frame 100. The electric push rod can control the pressing member to move towards the pressing table to press the fabric, or to move away from the pressing table to release the fabric.

[0049] The pressing component 221 fixes the fabric away from the second cutting edge, preventing the fabric from shifting during cutting and ensuring accurate cutting position. Meanwhile, the cutting machine 222 slides and cuts in the front-to-back direction, forming a neat first cutting edge. The combination of the two ensures cutting accuracy and prevents cutting deviations caused by fabric shaking, while also efficiently completing the cutting operation. This provides a neat cutting edge for the subsequent double-sided sewing process, improving the overall processing quality and efficiency.

[0050] This embodiment also includes a control component, which is electrically connected to the fabric cutting mechanism 200, the fabric feeding mechanism 300, the sewing mechanism 400, the first sewing head 410, and the second sewing head 420. The control component is an existing PLC control system.

[0051] In this embodiment, multiple rollers 600 are also provided on the frame 100 and on the side of the fabric cutting mechanism 200 away from the fabric feeding mechanism 300. The length of the multiple rollers 600 extends in the front-back direction so that the fabric is stretched by wrapping around and passing between adjacent rollers 600. This arrangement effectively eliminates problems such as wrinkles and looseness of the fabric before entering the fabric cutting mechanism 200, keeping the fabric flat and with uniform tension. This lays the foundation for the subsequent fabric cutting mechanism 200 to accurately cut the fabric to form regular first and second cut edges, avoiding cutting deviations caused by uneven fabric. This ensures the accuracy and quality of the subsequent sewing mechanism 400 in sewing the cut edges, while also reducing jamming or deviation of the fabric during the conveying process, improving the stability and efficiency of the overall processing flow.

[0052] In this embodiment, the sewing mechanism 400 further includes a first conveyor belt assembly 430 and a second conveyor belt assembly 440, which drive the first cut edge to align with and push into the sewing area of ​​the first head 410 via the first conveyor belt, and drive the second cut edge to align with and push into the sewing area of ​​the second head 420 via the second conveyor belt.

[0053] Preferably, the first conveyor belt assembly 430 and the second conveyor belt assembly 440 are conveying clamping structures. The conveying clamping structure includes a lower conveyor belt and an upper conveyor belt. The lower conveyor belt has a first conveying plane located on one side of the sewing area of ​​the first machine head 410 or the second machine head 420. The upper conveyor belt has a second conveying plane. The upper conveyor belt is slidably mounted on the frame 100. The second conveying plane and the first conveying plane are arranged opposite to each other so that the fabric is clamped by the first conveying plane and the second conveying plane to drive the first cutting edge to align and push into the sewing area of ​​the first machine head 410 or to drive the second cutting edge to align and push into the sewing area of ​​the second machine head 420.

[0054] The fabric is clamped between the first and second conveyor planes, which enhances the conveying force and prevents it from shifting or slipping during transport, ensuring that the cut edge always fits precisely against the sewing area of ​​the machine head. The clamping action also ensures the flatness of the fabric during the sewing process, reducing sewing quality problems caused by loose fabric. The combination of these two methods improves the accuracy and stability of double-sided sewing and enhances the reliability of automated conveying, effectively adapting to the needs of mass production, further reducing the processing error rate and improving production efficiency.

[0055] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0056] This invention relates to an automatic double-sided seam cutting mechanism. It comprises a fabric cutting mechanism 200, a fabric feeding mechanism 300, and a sewing mechanism 400. The mechanism cuts the rolled fabric into pieces and sews the two cut edges together. The fabric cutting mechanism 200 includes a moving component 210 and a cutting component 220. The moving component 210 pulls the rolled fabric above the fabric feeding mechanism 300, so that after the cutting component 220 cuts the fabric, it falls onto the fabric feeding mechanism 300. The fabric feeding mechanism 300 transports the cut fabric to the sewing mechanism 400, where the two cut edges are sewn together to complete the production process. This setup eliminates the problems of low efficiency and unstable precision caused by manual cutting in traditional processes, as well as the backlog of production capacity and time-consuming manual transfer caused by continuous sewing in the previous process and intermittent operation in the subsequent process. It simplifies the production process, reduces operational complexity, improves the consistency of sewing quality, is more suitable for the needs of large-scale production, and comprehensively improves production efficiency and product quality.
