Description

Technical Field

[0001] This utility model relates to the field of four-sided seam cutting technology, specifically a four-sided seam cutting device with anti-wrinkle function. Background Technology

[0002] In the textile processing industry, four-side sewing and cutting devices are widely used in the production of clothing, home textiles and other products. They are mainly used to sew and cut the four sides of fabrics to meet the process requirements of different products.

[0003] However, traditional four-sided sewing cutting devices often cause wrinkles in the fabric during operation due to uneven stress during the conveying, clamping and sewing process. These wrinkles not only affect the appearance of the product, but also reduce the flatness and quality of the sewing, thus affecting the overall quality and performance of the product. Utility Model Content

[0004] The purpose of this invention is to provide a four-sided sewing cutting device with anti-wrinkle function to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-sided sewing and cutting device with anti-wrinkle function, comprising a first conveying mechanism and a second conveying mechanism. The top of the first conveying mechanism and the second conveying mechanism are sequentially provided with a guide roller, a mounting frame, a limiting roller and a cutting mechanism along the conveying direction of the fabric. The top of the first conveying mechanism is provided with a feeding roller at the rear end of the guide roller. The top of the first conveying mechanism is provided with a transverse sewing mechanism between the limiting roller and the cutting mechanism. The top of the second conveying mechanism is provided with a longitudinal sewing mechanism between the limiting roller and the cutting mechanism. Electric push rods are symmetrically installed at the top of the inner side of the mounting frame. The bottom end of the electric push rod is fixedly connected to the mounting plate. A flattening mechanism is provided through the inner side of the mounting plate. The flattening mechanism is used to eliminate wrinkles caused by uneven force on the fabric from the source, so as to significantly improve the flatness of the finished product.

[0006] Preferably, the flattening mechanism includes a support shaft connected to the mounting plate via a bearing and a guide frame symmetrically welded to the bottom of the mounting plate. A flattening frame is slidably connected between the support shaft and the guide frame, and the flattening frame is used to push the fabric outward evenly. The flattening frame consists of a scraper and a guide cylinder fixed to the top of the scraper.

[0007] Preferably, a guide rod is fixedly connected to the front end of the flattening frame. The guide rod is configured as an L-shaped structure. A guide groove is formed on the inner surface of the guide frame, which forms a sliding structure with the guide rod. The guide groove is used to allow the guide rod to move vertically up and down.

[0008] Preferably, the top of the inner side of the flattening frame is symmetrically welded with limiting blocks, and the bottom surface of the support shaft is symmetrically provided with limiting grooves that form a sliding structure with the limiting blocks. The limiting grooves and limiting blocks cooperate to enable the flattening frame to make vertical linear movement along the support shaft.

[0009] Preferably, a servo motor is mounted on the top of the mounting plate, and a gear set is connected between the output end of the servo motor and a support shaft. A pulley set is connected between the output end of the servo motor and another support shaft, and the pulley set and the gear set cooperate to make the two support shafts rotate synchronously in opposite directions.

[0010] Preferably, the first conveying mechanism and the second conveying mechanism are arranged perpendicularly. The cutting mechanism includes an outer frame fixedly connected to the top of the first conveying mechanism and the second conveying mechanism, and cylinders symmetrically installed inside the outer frame. The bottom end of cylinder is connected to the cutting shears by screws.

[0011] Preferably, the longitudinal sewing mechanism includes a vertical frame fixedly connected to the top of the first conveying mechanism and the second conveying mechanism, and a second cylinder installed inside the vertical frame, with a sewing component installed at the bottom of the second cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This four-sided sewing and shearing device uses the pulley group, gear plate group and support shaft in the flattening mechanism to make two symmetrically arranged flattening frames rotate in opposite directions. This generates a horizontal thrust on both sides of the fabric through the flattening frames, so as to push the fabric outward evenly. At the same time, the flattening frames are dynamically raised and lowered by the cooperation of the guide frame, guide groove, guide rod, limit block and limit groove to avoid interference. By adopting this method, wrinkles caused by uneven stress on the fabric can be eliminated at the source, and the flatness of the finished product can be significantly improved.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 and Figure 6 This utility model provides a technical solution: a four-sided sewing cutting device with anti-wrinkle function, including a first conveying mechanism 1 and a second conveying mechanism 2. The top of the first conveying mechanism 1 and the second conveying mechanism 2 are respectively provided with a guide roller 7, a mounting frame 10, a limiting roller 8 and a cutting mechanism 5 along the conveying direction of the fabric. The top of the first conveying mechanism 1 is provided with a feeding roller 6 at the rear end of the guide roller 7. The top of the first conveying mechanism 1 is provided with a transverse sewing mechanism 3 between the limiting roller 8 and the cutting mechanism 5. The top of the second conveying mechanism 2 is provided with a longitudinal sewing mechanism 4 between the limiting roller 8 and the cutting mechanism 5. Specifically, after the fabric enters through the feed roller 6, it is stably conveyed by the limiting roller 8, the guide roller 7, the first conveying mechanism 1, and the second conveying mechanism 2 to ensure that the material enters the sewing area flat. After the fabric enters, the four sides of the fabric are sewn sequentially by the transverse sewing mechanism 3 and the longitudinal sewing mechanism 4. The cutting mechanism 5 then cuts the fabric precisely to finally obtain a product that meets the requirements.

[0017] Specifically, the device integrates processes such as feeding, flattening, conveying, sewing, and cutting into a continuous production line. Fabrics do not need to be transferred from entering the device to completing the processing, which effectively shortens the production cycle, increases the output per unit time, and meets the needs of industrialized mass production.

[0018] exist Figure 1 , Figure 2 and Figure 6In the middle: Electric push rods 11 are symmetrically installed on the top of the inner side of the mounting frame 10. The electric push rods 11 are used to drive the mounting plate 12 to move vertically. The bottom end of the electric push rods 11 is fixedly connected to the mounting plate 12.

[0019] Specifically, the electric push rod 11 can flexibly adjust the height of the mounting plate 12 and related mechanisms to ensure the flattening effect while avoiding excessive compression damage to the fabric.

[0020] exist Figures 1-6 In the middle: A flattening mechanism 9 is provided through the inner side of the mounting plate 12. The flattening mechanism 9 is used to eliminate wrinkles caused by uneven force on the fabric from the source, so as to significantly improve the flatness of the finished product. The flattening mechanism 9 includes a support shaft 904 connected to the mounting plate 12 through a bearing and a guide frame 906 symmetrically welded to the bottom end of the mounting plate 12. A flattening frame 905 is slidably connected between the support shaft 904 and the guide frame 906. The flattening frame 905 is used to push the fabric outward evenly. The flattening frame 905 consists of a scraper and a guide cylinder fixed to the top of the scraper. A guide rod 908 is fixedly connected to the front end of the flattening frame 905. The guide rod 908 is set with an L-shaped structure. A guide groove 907 is opened on the inner surface of the guide frame 906, which forms a sliding structure with the guide rod 908. The guide groove 907 is used to make the guide rod 908 move vertically up and down.

[0021] Specifically, during the synchronous reverse rotation of the flattening frame 905, since the flattening frame 905 is slidably connected to the support shaft 904 through the limiting block 910 and the limiting groove 909, and slidably connected to the guide frame 906 through the guide groove 907 and the guide rod 908, the flattening frame 905 makes a vertical up-and-down movement when it rotates one revolution. That is, when the flattening frame 905 is close to the material's forward direction, the guide block at the top of the flattening frame 905 will gradually descend along the guide groove 907, contact the fabric, and flatten the fabric with a uniform and stable force. When it moves away, the guide block at the top of the flattening frame 905 will gradually rise along the guide groove 907 and completely separate from the fabric, avoiding interference with the fabric's conveying.

[0022] exist Figure 3 and Figure 4 In the middle: the top of the inner side of the flattening frame 905 is symmetrically welded with a limiting block 910, and the bottom surface of the support shaft 904 is symmetrically provided with a limiting groove 909 that forms a sliding structure with the limiting block 910. The limiting groove 909 and the limiting block 910 cooperate to enable the flattening frame 905 to make a vertical linear movement along the support shaft 904.

[0023] Specifically, the cooperation between the limiting groove 909 and the limiting block 910 can achieve the support and limiting of the flattening frame 905, so that the flattening frame 905 can make vertical linear movement along the support axis 904.

[0024] exist Figures 1-3and Figure 5 In the middle: A servo motor 901 is installed at the top of the mounting plate 12. A gear set 902 is connected between the output end of the servo motor 901 and a support shaft 904. A pulley set 903 is connected between the output end of the servo motor 901 and another support shaft 904. The pulley set 903 and the gear set 902 cooperate to make the two support shafts 904 rotate synchronously in opposite directions.

[0025] Specifically, the servo motor 901 is started. The output end of the servo motor 901 drives the two support shafts 904 and the flattening frame 905 to rotate synchronously in opposite directions under the action of the pulley group 903 and the gear plate group 902. This causes the flattening frame 905 to generate a horizontal thrust on both sides of the fabric, so as to push the fabric outward evenly and thus eliminate wrinkles caused by uneven force at the source.

[0026] Specifically, the flattening mechanism 9 can flatten the fabric evenly and stably through the dual action of horizontal thrust and vertical lifting, eliminating wrinkles at the source and effectively avoiding problems such as sewing misalignment and cutting deviation caused by fabric wrinkles, thus significantly improving the appearance and dimensional accuracy of the final product.

[0027] exist Figure 1 In the middle: the cutting mechanism 5 includes an outer frame fixedly connected to the top of the first conveying mechanism 1 and the second conveying mechanism 2, and cylinders 1 symmetrically installed inside the outer frame. The bottom end of cylinder 1 is connected to the cutting blade by screws.

[0028] Specifically, when cutting is required, cylinder one is activated, which drives the cutting blades to move downwards to cut the fabric. The specific cutting process is existing technology and therefore is not described in detail.

[0029] exist Figure 1 In the middle: the longitudinal sewing mechanism 4 includes a vertical frame fixedly connected to the top of the first conveying mechanism 1 and the second conveying mechanism 2, and a cylinder 2 installed inside the vertical frame. A sewing component is installed at the bottom of the cylinder 2. The fabric is manually pulled or pulled by a robot during the conveying process. The specific conveying process of the fabric is existing technology and therefore not described in detail.

[0030] Specifically, after the fabric enters the sewing area, cylinder two and the sewing component are activated. Cylinder two drives the sewing component to move vertically so that the fabric can be sewn. The specific structure of the sewing component and the sewing process are existing technologies and therefore are not described in detail.

[0031] After the fabric enters through the feed roller 6, it is stably conveyed by the limiting roller 8, the guide roller 7, the first conveying mechanism 1, and the second conveying mechanism 2 to ensure that the material enters the sewing area flat. After the fabric enters, the four sides of the fabric are sewn in sequence by the transverse sewing mechanism 3 and the longitudinal sewing mechanism 4. The cutting mechanism 5 then cuts the fabric precisely to finally obtain a product that meets the requirements. During this process, the servo motor 901 is started. The output end of the servo motor 901 drives the two support shafts 904 and the flattening frame 905 to rotate synchronously in opposite directions under the action of the pulley group 903 and the gear plate group 902. This causes the flattening frame 905 to generate a horizontal thrust on both sides of the fabric during the conveying process, so as to push the fabric outward evenly and flatten it, thereby eliminating wrinkles caused by uneven force at the source. At the same time, the flattening frame 905 makes a vertical up-and-down movement when it rotates one revolution, thereby avoiding interference. Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source or a battery and controlled by a control box, control panel, or controller. Any content not described in detail in this document is prior art known to those skilled in the art.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
