Description

Technical Field

[0001] The utility model relates to the technical field of embroidery processing, in particular to a cloth flattening device for an embroidery machine. Background Technique

[0002] The embroidery machine plays a crucial role in the production process of modern textiles. Its working efficiency and quality have made remarkable progress compared with traditional manual embroidery, meeting the large demands of the modern textile industry. During the actual working process of the embroidery machine, the surface cloth and the bottom cloth are usually stitched together by embroidery, and after the embroidery is completed on the surface cloth, it is subsequently cut into finished products by laser.

[0003] During the operation and use of the existing cloth flattening device of the embroidery machine, usually only the edge parts of the surface cloth and the bottom cloth are fixed and flattened. In this way, it is very easy to cause the surface cloth and the bottom cloth to slide and generate wrinkles during the production process. At the same time, if the surface cloth comes into contact with the needle during the moving process, it will lead to the situation where the wrinkled part is stitched, making it difficult to flatten the embroidered part and reducing the quality of the embroidery. Summary of the Invention

[0004] The purpose of the utility model is to provide a cloth flattening device for an embroidery machine. By using this device for work, the problem that the existing cloth flattening device of the embroidery machine cannot ensure whether the embroidered part is flat when the cloth deviates is solved.

A fixing plate 3 is arranged inside the casing 1, and a roller pushing structure 6 is arranged at the bottom end of the fixing plate 3.

[0025] The present utility model will be further described below in conjunction with the embodiments. Embodiment

[0026] Please refer to Figures 1-5 , the roller pushing structure 6 includes an extension plate 61 arranged at the bottom end of the fixing plate 3. A rotating rod 62 is rotatably connected between the extension plates 61. A rotating plate 64 is arranged on one side of the rotating rod 62. A cross frame 65 is arranged at the bottom end of the rotating plate 64. A pushing roller 66 is rotatably connected between the cross frames 65. The pushing roller 66 is used to roll and flatten the wrinkles of the embroidered part. A pushing plate 68 is arranged on one side of the cross frame 65. The pushing plate 68 is used to push and flatten the wrinkles of the embroidered part. Hairsprings 63 are arranged at both ends of the rotating rod 62. The hairsprings 63 are connected to the extension plates 61. A long plate 67 is arranged on one side of the cross frame 65. The long plate 67 is in an L shape. The long plate 67 is fixedly connected to the pushing plate 68. Finally, the pushing roller 66 and the pushing plate 68 are driven to roll and push the fabric flat, ensuring that the fabric can remain flat during the embroidery process.

[0027] The bottom end of the fixed plate 3 is also rotatably connected with a pressing structure 4 for driving the roller pushing structure 6. The pressing structure 4 includes a rotating rod 41 rotatably connected to the bottom end of the fixed plate 3. A first bevel gear 46 is arranged on the surface of the rotating rod 41. A fixed sleeve 48 is arranged on one side of the first bevel gear 46. The fixed sleeve 48 is L-shaped. A second bevel gear 47 is arranged on the other side of the fixed sleeve 48. The first bevel gear 46 meshes with the second bevel gear 47. A twist rod 42 is arranged at the bottom end of the rotating rod 41. A twist sleeve 43 is threadedly connected to the outer end of the twist rod 42. A roller 49 is rotatably connected to the bottom end of the twist sleeve 43. A socket ring 44 is arranged at the outer end of the twist sleeve 43. A spring 45 is arranged on one side of the socket ring 44. The spring 45 is connected to the fixed plate 3, which is convenient for converting the extrusion force into mechanical transmission force.

[0028] The bottom end of the fixed plate 3 is also rotatably connected with a pushing structure 5 for driving the roller pushing structure 6. The pushing structure 5 includes a vertical plate 51 arranged at the bottom end of the fixed sleeve 48. A sleeve 54 is slidably connected to one side of the vertical plate 51. A screw rod 55 is threadedly connected to the inside of the sleeve 54. One end of the screw rod 55 is provided with a driven rod 56. The driven rod 56 is connected to the second bevel gear 47. The fixed sleeve 48 is rotatably connected to the rotating rod 41 and the driven rod 56 respectively. A chute 52 is formed on the surface of the vertical plate 51. A slider 53 is slidably connected to the inside of the chute 52. The slider 53 is connected to the sleeve 54, which is convenient for driving.

[0029] Specifically, during use, the casing 1 and the needle 2 are driven to move downward to perform embroidery work on the fabric. As a result, the roller 49 first contacts the fabric, and thus the roller 49 is squeezed. The roller 49 transmits the squeezing force to the twist sleeve 43, causing the twist sleeve 43 to be pressed and threadedly connected to the twist rod 42. The twist rod 42 drives the socket ring 44 to be pressed, and the socket ring 44 squeezes and stores energy in the spring 45. The twist rod 42 drives the rotating rod 41 to rotate. The rotating rod 41 is rotatably connected to the fixing plate 3. The rotating rod 41 drives the first bevel gear 46 to rotate and mesh with the second bevel gear 47. The second bevel gear 47 drives the driven rod 56 to rotate. The driven rod 56 is rotatably connected to the rotating rod 41 and the fixed sleeve 48. The fixed sleeve 48 is L-shaped and is fixedly connected to the first bevel gear 46 and the second bevel gear 47. The second bevel gear 47 drives the driven rod 56 on one side to rotate. The driven rod 56 drives the screw rod 55 to be threadedly connected to the sleeve 54. The sleeve 54 drives the slider 53 on one side to slide in the chute 52 formed on the surface of the vertical plate 51. The vertical plate 51 is connected to the fixing plate 3. The sleeve 54 moves to push the rotating plate 64. The rotating plate 64 is pushed to rotate through the rotating rod 62 at the top. The two ends of the rotating rod 62 are provided with clockwork springs 63. The rotating rod 62 is rotatably connected to the extension plate 61. The extension plate 61 is connected to the fixing plate 3. The rotating plate 64 drives the cross frame 65 to move. The cross frame 65 drives the push rollers 66 rotatably connected therebetween to expand and roll outwards. The push rollers 66 roll and flatten the fabric at the embroidered part. Moreover, the push plate 68 connected to the cross frame 65 through the long plate 67 also flattens the fabric. The squeezing force is converted into mechanical transmission, and finally the push rollers 66 and the push plate 68 are driven to roll and flatten the fabric, ensuring that the fabric can remain flat during the embroidery process and avoiding embroidery quality problems caused by fabric wrinkles.
