Description

Technical Field

[0001] This utility model relates to the field of knitted fabric production technology, specifically to a flattening device for knitted fabric production. Background Technology

[0002] Knitted fabrics are woven fabrics created by bending yarns into loops and interlocking them using knitting needles. The difference between knitted and woven fabrics lies in the form of the yarns within the fabric. Knitting is divided into weft knitting and warp knitting. Knitted fabrics are widely used in clothing fabrics and linings, home textiles, and other products, and are popular with consumers. In current knitted fabric production, smoothing equipment is used to achieve the desired fabric smoothness.

[0003] According to a public notice (Announcement No.: CN222119668U) of a flattening device for knitted fabric production, the aforementioned application utilizes a hydraulic rod to drive the cantilever and pressure block to move downwards. The pressure block is used to hold and fix the fabric in place to prevent it from loosening. Then, the motor is turned on, which drives the connecting rod to rotate. The connecting rod drives the gear to move on the outside of the toothed plate, and at the same time, it drives the flattening roller to move synchronously. The flattening roller is used to flatten the fabric on the operating table. This solves the problem in existing devices where the fabric is easily wrinkled during the conveyor belt movement process, which affects the flattening effect.

[0004] However, during use, because the size of the knitted fabric is different while the length of the flattening roller is fixed, the flattening roller needs to flatten the knitted fabric multiple times, which reduces the overall production efficiency and increases the production cycle.

[0017] like Figures 1-3 As shown, this utility model provides a technical solution: a flattening device for knitted fabric production, including a workbench 1. The bottom surface of the workbench 1 is fixedly connected to four sets of symmetrically arranged support legs 11. The workbench 1 is used to place the knitted fabric to be flattened. The four sets of symmetrically arranged support legs 11 on the bottom surface play a role in stabilizing and supporting the workbench 1, ensuring that the device remains stable during operation. Support plates 2 are fixedly connected to both sides of the surface of the workbench 1. The support plates 2 are used to install flattening components 3 and pressing components 4.

[0018] like Figures 1-3As shown, a leveling assembly 3 is provided between the opposing sidewalls of the two sets of support plates 2. The leveling assembly 3 includes a lead screw 31, the end of which is rotatably connected to the sidewall of the support plate 2. A movable platform 32 is threadedly connected to the outer wall of the lead screw 31. A through hole is provided on the sidewall of the movable platform 32, and a crossbar 33 is slidably connected in the through hole. The end of the crossbar 33 is fixedly connected to the sidewall of the support plate 2. A motor is fixedly connected to the sidewall of the support plate 2. The output shaft of the motor passes through and is rotatably connected to the sidewall of the support plate 2. The output shaft of the motor is fixedly connected to the end of the lead screw 31. The output shaft of the motor is used to drive the lead screw 31 to rotate. The crossbar 33 guides the movable platform 32, causing the movable platform 32 to move linearly along the direction of the crossbar 33, thus ensuring the accuracy of the movement of the movable platform 32. like Figures 1-3 As shown, the surface of the moving table 32 has two sets of symmetrically arranged through holes, and each through hole is slidably connected to a slide rod 34. The tops of the two sets of slide rods 34 are fixedly connected by a connecting rod 35, and the bottom of the connecting rod 35 is fixedly connected to a fixing frame 36. The fixing frame 36 is elastically connected to the bottom surface of the moving table 32 by a spring. The bottom surface of the fixing frame 36 is fixedly connected to a pressure plate 37. The slide rods 34 and the fixing frame 36 are used to position the pressure plate 37, so that the moving table 32 can drive the pressure plate 37 to move synchronously, and the pressure plate 37 moves vertically downward under the elastic force of the spring, thereby flattening the knitted fabric placed on the surface of the workbench 1 through the pressure plate 37. The bottoms of the two sets of slide rods 34 are connected together by the connecting rod 35, so that the two sets of slide rods 34 can move synchronously. When it is necessary to remove the knitted fabric, the connecting rod 35 is manually raised, so that the two sets of slide rods 34 drive the pressure plate 37 to squeeze the spring and move away from the surface of the knitted fabric, thereby making it easier to pick up or place the knitted fabric.

[0019] like Figures 1-3 As shown, the bottom surface of the pressure plate 37 has a groove 38, and two sets of symmetrically arranged extension plates 39 are slidably connected inside the groove 38. The bottom surface of the extension plates 39 is at the same level as the bottom surface of the pressure plate 37. A protrusion 310 is fixedly connected to the surface of the extension plates 39, and a through groove 311 is provided on the surface of the pressure plate 37 for the protrusion 310 to pass through. The two sets of protrusions 310 are threadedly connected by a bidirectional threaded rod 312, and a rotating wheel 313 is fixedly connected to the middle part of the outer wall of the bidirectional threaded rod 312. The groove 38 is used to install the extension plates 39, and the through groove 311 provides a track for the protrusions 310 to slide. The extension plates 39 are connected to the bidirectional threaded rod 312 through the protrusions 310. By rotating the rotating wheel 313, the bidirectional threaded rod 312 is rotated, thereby causing the protrusions 310 to drive the extension plates 39 to move towards each other or away from each other, thereby changing the position of the extension plates 39 and thus changing the effective flattening width of the flattening component 3 to adapt to different sizes of knitted fabrics.

[0020] like Figures 1-3 As shown, a clamping assembly 4 is provided on the side wall of the support plate 2. The clamping assembly 4 includes a mounting groove 41, which is formed on the side wall of the support plate 2. A sliding plate 42 is slidably connected inside the mounting groove 41. The mounting groove 41 is used to install the sliding plate 42, providing space and guidance for the sliding plate 42 to slide, allowing the sliding plate 42 to move up and down within the mounting groove 41. A fixing seat 43 is fixedly connected to the side wall of the support plate 2. A through hole is formed on the surface of the fixing seat 43, and a threaded rod 44 is threadedly connected to the through hole. The bottom end of the threaded rod 44 is rotatably connected to the surface of the sliding plate 42, and a handwheel 45 is fixedly connected to the top end of the threaded rod 44. By rotating the threaded rod 44, the sliding plate 42 moves downward, and the guide rod 46 drives the clamping plate 47 to move downward synchronously. The clamping plate 47 clamps the edge of the knitted fabric to prevent the fabric from moving or wrinkling during the flattening process. The side wall of the slide plate 42 has a through hole, and a guide rod 46 is slidably connected in the through hole. A clamping plate 47 is fixedly connected to the end of the guide rod 46. A threaded rod 48 is rotatably connected to the side wall of the clamping plate 47. The threaded rod 48 passes through and is threadedly connected to the side wall of the slide plate 42. A handwheel 49 is fixedly connected to the end of the threaded rod 48. By rotating the handwheel 49, the threaded rod 48 is rotated. The guide rod 46 restricts the movement direction of the clamping plate 47, causing the clamping plate 47 to move linearly along the direction of the guide rod 46. This adjusts the distance between the clamping plate 47 and the edge of the knitted fabric, thus making it suitable for clamping knitted fabrics of different lengths.

[0021] In this invention, the knitted fabric to be flattened is placed on the workbench 1. Depending on the fabric length, the second handwheel 49 is rotated, causing the second threaded rod 48 to rotate. The clamping plate 47, restricted by the guide rod 46, moves linearly along the direction of the guide rod 46, bringing the clamping plate 47 close to the upper edge of the knitted fabric. The first handwheel 45 is then rotated, causing the first threaded rod 44 to rotate, allowing the slide plate 42 to slide downwards within the mounting groove 41, clamping the edge of the knitted fabric onto the workbench 1. This prevents the fabric from shifting or wrinkling during subsequent flattening. If the effective flattening width of the current pressure plate 37 cannot match the size of the knitted fabric, the rotating wheel 313 is rotated, causing the bidirectional threaded rod 312 to rotate accordingly. This, through the protrusion 310, causes the extension plate 39 to move in opposite directions or back-to-back within the groove 38, thereby changing the effective flattening width of the flattening component 3 to fit the fabric size.

[0022] The pressure plate 37 is positioned by the slide bar 34 and the fixed frame 36, allowing the moving table 32 to move the pressure plate 37 synchronously. A spring causes the pressure plate 37 to contact the surface of the knitted fabric with appropriate pressure. The motor on the side wall of the support plate 2 is activated, and the motor's output shaft drives the lead screw 31 to rotate. Under the threaded transmission of the lead screw 31 and the guidance of the crossbar 33, the moving table 32 moves linearly along the direction of the crossbar 33, thus effectively smoothing the knitted fabric.

[0023] Once the knitted fabric is flattened, turn the handwheel 45 in the opposite direction to loosen the clamping plate 47 and raise its height. Manually lift the connecting rod 35, and the slide rod 34 will drive the pressure plate 37 to move upward and squeeze the spring, so that the pressure plate 37 is away from the surface of the knitted fabric. Remove the flattened knitted fabric from the workbench 1.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
