Description

Technical Field

[0001] This invention relates to the field of textile fabric flattening technology, and more particularly to a textile fabric pre-flattening device. Background Technology

[0002] Sometimes, fabric wrinkles will occur during the textile process.

[0003] To eliminate wrinkles in textile fabrics, pre-smoothing is necessary. Currently, pre-smoothing typically involves manual ironing using an ironing device, but this method is inefficient. To improve efficiency, factories use pre-smoothing devices. These devices generally use a flat plate structure to press the fabric flat, operating on the same principle as ironing. However, current pre-smoothing devices cannot detect wrinkles, sometimes pressing them down and creating creases, thus reducing the smoothness. Therefore, this application proposes a textile fabric pre-smoothing device. Summary of the Invention

[0004] The purpose of this invention is to provide a pre-flattening device for textile fabrics to solve the problem of poor flattening effect of current pre-flattening devices for textile fabrics.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A textile fabric pre-smoothing device, the pre-smoothing device comprising:

[0007] A support frame, on which a flat worktable is provided;

[0008] A leveling unit mounted on the support is used to level the fabric located on the worktable. The leveling unit is positioned above the worktable and includes:

[0009] A lifting assembly is mounted on the support, and the lifting assembly has a lifting plate that can be raised and lowered above the workbench;

[0010] Two sets of flat rollers are hinged to the lifting plate. Each flat roller has a cylindrical and horizontally arranged roller body. When the lifting plate descends, the two roller bodies slide on the fabric to both sides to tighten the fabric.

[0011] The limiting part provided on the lifting assembly and the leveling roller is used to limit the leveling roller to control the roller body from rotating inward to the inside of the fabric when it is detached from the fabric, and to release the limiting part on the roller body when the lifting plate rises to a preset height so that the two roller bodies can move closer to each other.

[0012] The steam unit located on the workbench is used to generate steam to soften the fabric.

[0013] Furthermore, the lifting assembly includes:

[0014] A lifting part is fixedly connected to the bracket, and the output shaft of the lifting part is fixedly connected to the lifting plate to drive the lifting plate to rise and fall.

[0015] A guide tube fixedly connected to the lifting plate;

[0016] A guide rod is fixedly connected to the bracket, and a guide tube is disposed inside the guide rod and slidably connected to the guide rod.

[0017] Furthermore, at least two sets of the guide tube and the guide rod are provided.

[0018] Furthermore, the leveling roller also includes:

[0019] Connecting arms are provided at both ends of the roller body, the connecting arms are perpendicular to the roller body, and the end of the connecting arm away from the roller body is hinged to the side of the lifting plate near the worktable.

[0020] Furthermore, the surface of the roller body is smooth.

[0021] Furthermore, the leveling unit also includes:

[0022] An elastic portion is provided on the leveling roller, and the two ends of the elastic portion are respectively connected to two connecting arms to tighten the connecting arms.

[0023] Furthermore, the limiting part includes:

[0024] The telescopic part is fixedly connected to the lifting plate;

[0025] A limiting ring is fixedly connected to the output shaft of the telescopic part. The limiting ring is sleeved on the connecting arm. The telescopic part is used to change the height between the limiting ring and the lifting plate to limit the roller body.

[0026] The detection unit, fixedly connected to the lifting plate, is used to detect the angle of the connecting arm in order to control the extension length of the output shaft on the telescopic part.

[0027] Furthermore, the pre-leveling device also includes:

[0028] The feeding units located at both ends of the support are used to control the movement of the fabric between the roller body and the worktable;

[0029] The control unit is used to control the feeding unit, the lifting assembly and the limiting part to work together to control the fabric to stop moving during pre-flattening and to remove it from the worktable after pre-flattening.

[0030] Furthermore, the feed unit includes:

[0031] Roller supports are provided on both sides of the support;

[0032] The first roller and the second roller, which are rotatably connected to the roller support, are tangent to each other.

[0033] A roller motor fixedly connected to the roller bracket is used to drive the second roller to rotate intermittently.

[0034] Furthermore, the smoothing unit is provided in two sets. The steam section is located below the smoothing unit upstream in the fabric movement direction, and the drying section is located below the smoothing unit downstream for air-drying the fabric.

[0035] In summary, the present invention has the following advantages compared with the prior art:

[0036] The textile fabric pre-flattening device disclosed in this embodiment of the invention sets up a lifting component and a flattening roller. When the lifting component controls the lifting plate located on the lifting component to descend, the two roller bodies on the flattening roller move away from each other to tension the fabric. Steam is also injected into the fabric through the steam section to soften the fabric, thereby preventing wrinkles from forming in the fabric during the flattening process and improving the pre-flattening effect of the fabric.

[0051] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0052] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides a textile fabric pre-flattening device, the pre-flattening device comprising:

[0053] Support 1, on which a flat workbench 11 is provided;

[0054] A leveling unit mounted on the support 1 is used to level the fabric located on the workbench 11. The leveling unit is positioned above the workbench 11, and includes:

[0055] A lifting assembly 3 is provided on the support 1, and the lifting assembly 3 is provided with a lifting plate 31 that can be raised and lowered above the workbench 11;

[0056] Two sets of flat rollers 4 are hinged to the lifting plate 31. The flat rollers 4 are provided with cylindrical and horizontally arranged roller bodies 41. When the lifting plate 31 descends, the two roller bodies 41 slide on the fabric to both sides of the fabric to tighten the fabric.

[0057] The limiting part 5 provided on the lifting assembly 3 and the flattening roller 4 is used to limit the flattening roller 4 to control the roller body 41 from rotating inward to the inside of the fabric when it is detached from the fabric, and to release the limiting part on the roller body 41 when the lifting plate 31 rises to a preset height so that the two roller bodies 41 can move closer to each other.

[0058] The steam unit 7, located on the workbench 11, is used to generate steam to soften the fabric.

[0059] In this embodiment, during fabric pre-flattening, the steam unit 7 generates steam that is sprayed onto the fabric to soften it. At this time, the lifting assembly 3 controls the lifting plate 31 to descend. As the lifting plate 31 descends, the roller bodies 41 abut against the fabric. As the lifting plate 31 continues to descend, it forces the two roller bodies 41 to move towards both sides of the fabric. Due to the gravity of the roller bodies 41, they slide on the fabric, causing the fabric to become taut. Because the fabric has been softened by steam beforehand, it can maintain a flat state after being taut. After a preset fabric tensioning time... The roller body 41 is limited by the limiting part 5, and then the lifting plate 31 is controlled to rise by the lifting assembly 3. At this time, the roller body 41 and the lifting plate 31 maintain a relative position under the action of the limiting part 5. During the rising process of the lifting plate 31, the two roller bodies 41 will not approach each other, thereby preventing the fabric from being piled up and wrinkled by the roller bodies 41. When the lifting plate 31 rises to the preset height, the limiting part 5 releases the limiting of the roller body 41, so that the roller bodies 41 approach each other, thereby preparing for the next leveling. At this time, neither of the two roller bodies 41 is in contact with the fabric.

[0060] In one embodiment of this invention, the bracket 1 further includes a support rod 12 and an upper bracket 13. The two ends of the support rod 12 are respectively fixed to the workbench 11 and the upper bracket 13 by bolts, thereby creating a preset height between the upper bracket 13 and the workbench 11, so that the lifting plate 31 has a lifting space. The workbench 11 is a steel plate, the upper bracket 13 is a steel plate, and the upper bracket 13 is provided with reinforcing ribs to prevent deformation.

[0061] The bottom of the workbench 11 is also provided with a support leg 14, which is fixedly connected to the workbench 11 by bolts or welding to support the workbench 11.

[0062] In a preferred embodiment of this invention, the lifting component 3 includes:

[0063] A lifting part 32 is fixedly connected to the upper bracket 13, and the output shaft of the lifting part 32 is fixedly connected to the lifting plate 31 to drive the lifting plate 31 to rise and fall;

[0064] Guide tube 33 fixedly connected to the lifting plate 31;

[0065] A guide rod 34 is fixedly connected to the upper bracket 13, and a guide tube 33 is disposed inside the guide rod 34 and slidably connected to the guide rod 34;

[0066] In this embodiment, the lifting part 32 is a telescopic cylinder. When the lifting plate 31 is raised or lowered, the lifting plate 31 is raised or lowered by controlling the air pressure inside the lifting plate 31. The output shaft of the lifting part 32 is fixedly connected to the lifting plate 31 by bolts.

[0067] The guide tube 33 is fixedly connected to the lifting plate 31 by bolts. The guide rod 34 is a cylindrical shape with openings at both ends. The guide rod 34 is fixedly connected to the upper bracket 13 by bolts. The guide tube 33 is a round rod and the guide rod 34 is a round tube. The guide tube 33 and the guide rod 34 are used to limit the lifting plate 31 to prevent the lifting plate 31 from rotating.

[0068] Preferably, at least two sets of the guide tube 33 and the guide rod 34 are provided;

[0069] like Figure 5 As shown, the leveling roller 4 further includes:

[0070] Connecting arms 42 are provided at both ends of the roller body 41. The connecting arms 42 are perpendicular to the roller body 41. The end of the connecting arm 42 away from the roller body 41 is hinged to the side of the lifting plate 31 near the worktable 11. When the lifting plate 31 descends, the two connecting arms 42 rotate away from each other, thereby causing the roller body 41 to rotate towards both sides of the fabric.

[0071] The lifting plate 31 is provided with a first lug, and the connecting arm 42 is hinged to the first lug by a first pin.

[0072] In some examples, the roller body 41 and the connecting arm 42 are fixedly connected by welding;

[0073] Preferably, the surface of the roller body 41 is smoothly configured to prevent the roller body 41 from scratching the fabric;

[0074] In some examples, the roller body 41 is a metal roller;

[0075] In a preferred embodiment of this invention, the limiting part 5 includes:

[0076] Telescopic part 52 is fixedly connected to the lifting plate 31;

[0077] A limiting ring 51 is fixedly connected to the output shaft of the telescopic part 52. The limiting ring 51 is sleeved on the connecting arm 42. The telescopic part 52 is used to change the height between the limiting ring 51 and the lifting plate 31 to limit the roller body 41.

[0078] The detection unit 53, which is fixedly connected to the lifting plate 31, is used to detect the angle of the connecting arm 42 in order to control the extension length of the output shaft on the telescopic part 52;

[0079] In this embodiment, when the roller body 41 controls the fabric tension, the angle of the connecting arm 42 can be calculated based on the fabric width to obtain a preset value. When the detection unit 53 detects that the angle of the connecting arm 42 has reached the preset value for a preset time, the output shaft of the telescopic unit 52 retracts, causing the telescopic unit 52 to lift the connecting arm 42, thereby lifting the roller body 41 off the fabric. At this time, after the lifting plate 31 rises, the telescopic unit 52 can limit the connecting arm 42 through the limiting ring 51 to prevent the connecting arm 42 from being lifted. Arm 42 rotates downward due to gravity, thus preventing the two roller bodies 41 from getting close to each other. After the lifting plate 31 rises to a preset height (the height of the lifting plate 31 is determined by the length of the output shaft of the lifting part 32), the air pressure in the telescopic part 52 changes, causing the output shaft of the telescopic part 52 to extend. At this time, the connecting arm 42 rotates downward due to gravity, and the two roller bodies 41 get close to each other. When the lifting plate 31 descends again, the two roller bodies 41 can slide on the fabric to tension the fabric.

[0080] like Figure 3 and Figure 4 As shown, the limiting ring 51 is a square frame, and the limiting ring 51 is fixedly connected to the output shaft of the telescopic part 52 by bolts; the connecting arm 42 is a square tube.

[0081] The height of the square hole inside the limiting ring 51 is greater than the thickness of the connecting arm 42 so that the connecting arm 42 can swing around its own rotation center within the limiting ring 51.

[0082] In some examples, the detection unit 53 is a distance sensor fixedly connected to the lifting plate 31, used to detect the distance between the lifting plate 31 and the upper bracket 13 in order to detect the angle of the connecting arm 42;

[0083] In a preferred embodiment of this invention, the steam section 7 is a cavity disposed within the workbench 11. A permeable plate 71 is disposed on the side of the steam section 7 near the leveling roller 4. Permeable holes are evenly distributed on the permeable plate 71. The steam section 7 is connected to a steam source.

[0084] In some examples, the vent plate 71 is a smooth flat plate, the vent plate 71 is fixedly connected to the steam section 7 by screws, and the diameter of the vent holes on the vent plate 71 is less than 1 mm;

[0085] When flattening the fabric, the steam in the steam source is introduced into the steam section 7 and sprayed onto the fabric through the air holes on the breathable plate 71 to soften the fabric.

[0086] In some examples, the steam unit 7 is fixedly connected to the workbench 11 by screws.

[0087] As a further embodiment of the present invention, the leveling unit further includes:

[0088] An elastic part 6 is provided on the flattening roller 4. The two ends of the elastic part 6 are respectively connected to two connecting arms 42 to tighten the connecting arms 42, which is used to increase the pressure between the roller body 41 and the fabric to increase the tension of the fabric.

[0089] In this embodiment, as Figure 5 As shown, the connecting arm 42 is provided with a connecting lug 43, and the elastic part 6 is a tension spring. The two ends of the elastic part 6 hook the connecting lug 43 to tighten the two connecting arms 42. When the two flat rollers 4 are opened, the downward pressure of the lifting plate 31 increases due to the tension of the elastic part 6, thereby increasing the pressure between the roller body 41 and the fabric.

[0090] As a further embodiment of the present invention, the pre-leveling device further includes:

[0091] The feeding units 2 located at both ends of the support 1 are used to control the movement of the fabric between the roller body 41 and the worktable 11;

[0092] The control unit is used to control the feeding unit 2, the lifting assembly 3 and the limiting part 5 to work together to control the fabric to stop moving during pre-flattening and to remove it from the worktable 11 after pre-flattening.

[0093] In this embodiment, the feed unit 2 includes:

[0094] Roller supports 21 are provided on both sides of the support 1;

[0095] The first roller 22 and the second roller 23, which are rotatably connected to the roller bracket 21, are tangent to each other.

[0096] A roller motor 24, fixedly connected to the roller bracket 21, is used to drive the second roller 23 to rotate intermittently.

[0097] In this embodiment, the roller motor 24 is fixedly connected to the roller bracket 21 by bolts, the first roller 22 and the second roller 23 are rotatably connected to the roller bracket 21 by bearings, the roller bracket 21 is disposed at both ends of the first roller 22 and the second roller 23, a first pulley is fixedly connected to the second roller 23, and a second pulley is fixedly connected to the output shaft of the roller motor 24, and the first pulley and the second pulley are connected by a belt;

[0098] Preferably, the control unit is a PLC controller, and the control unit is electrically connected to the lifting part 32, the telescopic part 52, the detection part 53 and the roller motor 24 via wires.

[0099] As a further embodiment of the present invention, the smoothing unit is provided in two sets, wherein the steam unit 7 is provided below the smoothing unit located upstream in the fabric moving direction, and the drying unit 8 is provided below the smoothing unit located downstream for air drying the fabric.

[0100] In this embodiment, the drying section 8 is an internal hollow cavity. The drying section 8 has a vent on the side near the flattening unit. The drying section 8 is connected to a negative pressure device. When the flattened fabric moves to the position of the drying section 8, a negative pressure is generated inside the drying section 8, allowing external control to enter the drying section 8 through the fabric, thereby increasing the airflow around the fabric and improving the drying effect of the fabric.

[0101] The drying section 8 is fixedly connected to the workbench 11 by bolts.

[0102] In summary, the textile fabric pre-flattening device disclosed in this embodiment of the invention, by setting up a lifting component 3 and a flattening roller 4, when the lifting component 3 controls the lifting plate 31 located on the lifting component 3 to descend, the two roller bodies 41 on the flattening roller 4 move away from each other to tension the fabric, and steam is sprayed onto the fabric through the steam section 7 to soften the fabric, thereby preventing wrinkles from forming on the fabric during the flattening process and improving the pre-flattening effect of the fabric.
