Description

Technical Field

[0001] This utility model relates to the technical field of garment production equipment, specifically a fabric leveling structure. Background Technology

[0002] Utility model patent CN221523040U discloses a dyeing and printing device for shirt processing. The device includes a dyeing tank, with a fabric leveling component fixedly installed on the upper right side of the tank. The fabric leveling component includes an outer frame, with a first wrinkle-removing roller and a second wrinkle-removing roller movably mounted on the upper inner side of the outer frame. Shirt fabric is inserted into the inner part of the outer frame, and the first and second wrinkle-removing rollers respectively cover the two sides of the shirt fabric surface. A drive motor is fixedly installed on the top of the outer frame, and the output shaft of the drive motor is fixed to the rotating shaft of a drive gear, which in turn is fixed to an upper pulley. This utility model utilizes the friction between the first wrinkle-removing roller and the fabric surface to pull and wrinkle the fabric to the left; and utilizes the friction between the second wrinkle-removing roller and the shirt fabric surface to pull and wrinkle the fabric to the right. This allows for the smoothing and wrinkle removal of shirt fabric before dyeing, improving the dyeing quality of the shirt fabric.

[0003] However, since this invention achieves wrinkle removal by applying two opposing forces to the fabric, it can only remove wrinkles from the fabric portion between the points of application of the two forces (i.e., between the bottom ends of the two wrinkle-removing rollers). Furthermore, the distance between the two wrinkle-removing rollers is fixed. Therefore, this invention is only applicable to fabrics of a certain width. If the width of the fabric is less than the distance between the bottom ends of the two wrinkle-removing rollers, the fabric cannot simultaneously contact both rollers; if the width of the fabric is greater than the distance between the two rollers, the portion of the fabric from its edge to the bottom end of the rollers cannot be wrinkled.

[0004] Therefore, this utility model proposes a technical solution to solve the problem that the fixed spacing between the two wrinkle-removing rollers cannot be adjusted according to the width of the fabric. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fabric flattening structure, which aims to achieve the technical effect of adjusting the interval between two wrinkle-removing rollers according to the width of the fabric, thereby improving the applicability and ensuring that fabrics of different widths can be fully flattened.

[0006] A fabric leveling structure includes a leveling structure body, the leveling structure body including an upper pressing part and a lower supporting part located directly below the upper pressing part;

[0007] The upper pressing part includes a U-shaped frame and two wrinkle-removing components. The U-shaped frame includes a top plate and side plates fixed to the front and rear sides of the bottom end of the top plate. A first mounting plate for fixed connection to an external device is fixed to the rear side of the top plate. The two wrinkle-removing components are symmetrically arranged. Each wrinkle-removing component includes an upper shaft, a lower shaft, a wrinkle-removing roller, two sliders, and two first arc-shaped through slots. The upper shaft is rotatably connected between the two side plates via bearings. The rear end of the upper shaft passes through the rear side plate and is fixed with a gear. The front end of the upper shaft passes through the front side plate and is fixed with a drive wheel. The two first arc-shaped through slots are respectively opened on the two side plates and are symmetrically arranged front and rear. The first arc-shaped through slots are concentric and coaxial with the upper shaft. The two sliders are slidably connected to the two first arc-shaped through slots in a mating connection manner. Within the through groove, and symmetrically arranged front and back, each of the two sliders has a limiting plate fixed on its opposite side, which fits against the side plate. The limiting plate has a fixing structure for fixing the limiting plate to the side plate. The lower shaft is rotatably connected between the two limiting plates through a bearing. The front end of the lower shaft passes through the front slider and is fixed with a driven wheel. The driven wheel and the driving wheel are connected by a transmission belt. The wrinkle-removing roller is located between the two side plates and is fixedly sleeved on the outside of the lower shaft. The bottom end of the wrinkle-removing roller extends to the bottom of the side plate. The radius of the wrinkle-removing roller is greater than the height difference between the two ends of the first arc-shaped through groove. The gears in the two wrinkle-removing roller assemblies mesh with each other. A fixing plate is fixed to the bottom end of the first mounting plate. A first motor for driving one of the gears to rotate is mounted on the fixing plate.

[0008] The lower support includes a base plate, a support plate, and a lifting assembly. A second mounting plate for fixed connection to an external device is fixed to the rear side of the base plate. The support plate is located above the base plate and directly below the two wrinkle removal components. The lifting assembly is connected between the base plate and the support plate and is used to drive the support plate to move up and down.

[0009] By adopting the above technical solution, the fabric wrinkling process is as follows: After placing the fabric on top of the support plate, adjust the position of the wrinkling rollers according to the width of the fabric, so that the bottom ends of both wrinkling rollers correspond to the edges of the fabric. Then, the lifting assembly moves the support plate upwards, which in turn moves the fabric upwards until the fabric is pressed between the support plate and the two wrinkling rollers. Next, the first motor is started, driving the connected gear to rotate, which in turn drives the upper shaft to rotate. The upper shaft drives the drive wheel to rotate. The drive wheel drives the driven wheel to rotate. The driven wheel drives the lower shaft to rotate. The lower shaft drives the wrinkling roller to rotate. Simultaneously, because the two gears mesh, the other gear rotates synchronously in the opposite direction, thereby driving the other wrinkling roller to rotate synchronously in the opposite direction.

[0010] The process of adjusting the position of the wrinkle-removing roller is as follows: First, loosen the fixing structure so that the limiting plate is no longer fixed to the side plate, allowing the slider to slide freely in the first arc-shaped groove. Then, the wrinkle-removing roller drives both limiting plates to move simultaneously. The limiting plates drive the slider to slide along the first arc-shaped groove. Since the first arc-shaped groove is concentric and coaxial with the upper shaft, the distance between the axes of the driven wheel and the driving wheel remains constant regardless of the slider's position. The transmission belt between the driven wheel and the driving wheel also remains taut, ensuring a continuous transmission connection between them. After the wrinkle-removing roller is in position, tighten the fixing structure to fix the limiting plate to the side plate. The limiting plate cannot move, thus fixing the position of the slider and the wrinkle-removing roller. During the movement of the wrinkle-removing roller, its position changes not only in the left and right lateral directions but also in its height. Because the bottom of the wrinkle-removing roller extends below the side plate, its radius is greater than the height difference between the two ends of the first arc-shaped groove. Therefore, regardless of the height of the wrinkle-removing roller, its bottom will extend to the bottom of the side plate.

[0011] This invention can adjust the spacing between the two wrinkle-removing rollers according to the width of the fabric, thereby expanding its applicability and ensuring that fabrics of different widths can be fully flattened.

[0012] Further features of this invention: The fixing structure includes a handheld rod and two second arc-shaped through slots. The two second arc-shaped through slots are respectively opened on the two side plates and are symmetrically arranged front and back. The two second arc-shaped through slots correspond to the upper part of the two first arc-shaped through slots. The second arc-shaped through slots and the first arc-shaped through slots are concentric and coaxial. The top of each of the two limiting plates is fixed with an extension plate that fits against the side plate. The handheld rod is fixedly connected between the two extension plates. On the opposite side of each of the two extension plates, a screw corresponding to the second arc-shaped through slot is fixed. The screw slides along the second arc-shaped through slot. The end of the screw that is opposite to the extension plate passes through the side plate through the second arc-shaped through slot and is threadedly connected with a nut that is tightened on the outer wall of the side plate.

[0013] By employing the above technical solution, when it is necessary to loosen the fixing structure, simply loosen the nut, and the screw can slide freely in the second arc-shaped through groove. Moving the extension plate by holding the handle causes the screw to slide along the second arc-shaped through groove, and simultaneously, the extension plate moves the limiting plate. The limiting plate then causes the slider to slide in the first arc-shaped through groove. Similarly, when it is necessary to lock the fixing structure, simply tighten the nut.

[0014] Further details of this invention: The lifting assembly includes an upper guide rail assembly, a lower guide rail assembly, an X-shaped bracket, and a second motor. The upper guide rail assembly includes an upper guide rod, two upper fixed blocks, and two upper sliding blocks. Both upper fixed blocks are fixed to the bottom of the support plate and are symmetrically arranged left and right. The upper guide rod is fixedly connected between the two upper fixed blocks and extends laterally left and right. Both upper sliding blocks are slidably sleeved on the outside of the upper guide rod. The lower guide rail assembly includes a lower guide rod, a positive and negative threaded rod, two lower fixed blocks, and two lower sliding blocks. Both lower fixed blocks are fixed to the top of the base plate and are symmetrically arranged left and right. The lower guide rod is fixedly connected between the two lower fixed blocks. Extending laterally to the left and right, the positive and negative threaded rods are rotatably connected between two lower fixed blocks via bearings, and their extension direction is consistent with that of the lower guide rod. Both lower sliding seats are slidably sleeved on the outside of the lower guide rod, and are respectively threaded onto the positive and negative threaded parts of the positive and negative threaded rods. The second motor is mounted on one of the lower fixed blocks to drive the positive and negative threaded rods to rotate. The X-shaped bracket consists of two connecting rods, with the middle positions of the two connecting rods rotatably connected by a pin. The top ends of the two connecting rods are rotatably connected to the two upper sliding seats via pins, and the bottom ends of the two connecting rods are rotatably connected to the two lower sliding seats via pins.

[0015] By adopting the above technical solution, when it is necessary to move the support plate up and down via the lifting assembly, the second motor is activated. The second motor drives the forward and reverse threaded rods to rotate. The forward and reverse threaded rods drive the two sliding blocks on them to move in opposite directions along the forward and reverse threaded rods and the lower guide rod. The two sliding blocks drive the X-shaped bracket to fold or unfold. The X-shaped bracket drives the two upper sliding blocks to move in opposite directions along the upper guide rod, and at the same time drives the two upper sliding blocks to move up and down. The upper sliding blocks drive the support to move up and down.

[0016] A further feature of this invention is that a buffer plate is provided at the top of the support plate, and a plurality of buffer springs are connected between the buffer plate and the support plate.

[0017] By adopting the above technical solution, the upward movement of the support plate causes the buffer plate to move upward until it presses against the bottom of the wrinkle-removing roller. At this point, the buffer plate moves downward relative to the support plate, and the buffer spring is pressed to create a cushioning effect. Furthermore, by observing the movement of the buffer plate relative to the support plate, the operator can quickly determine whether the buffer plate and the wrinkle-removing roller are pressed tightly together, thereby ensuring that the wrinkle-removing roller applies sufficient and appropriate pressure to the fabric.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] A fabric smoothing structure is disclosed. This invention can adjust the spacing between two wrinkle-removing rollers according to the width of the fabric, thereby expanding its applicability and ensuring that fabrics of different widths can be fully smoothed. Attached Figure Description

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.

[0026] A fabric smoothing structure, such as Figures 1-4 As shown, it includes a leveling structure body. The leveling structure body includes an upper pressing part and a lower support part located directly below the upper pressing part.

[0027] The upper pressing part includes a U-shaped frame 1 and two wrinkle removal components.

[0028] The U-shaped frame 1 includes a top plate 2 and side plates 3 fixed to the front and rear sides of the bottom end of the top plate 2 respectively. A first mounting plate 4 for fixing and connecting to external equipment is fixed to the rear side of the top plate 2.

[0029] The two wrinkle-removing components are arranged symmetrically on the left and right. The wrinkle-removing components include an upper shaft 5, a lower shaft 6, a wrinkle-removing roller 7, two sliders 8, and two first arc-shaped through slots 9.

[0030] The upper shaft 5 is rotatably connected between the two side plates 3 via bearings. The rear end of the upper shaft 5 passes through the rear side plate 3 and is fixed with a gear 10. The front end of the upper shaft 5 passes through the front side plate 3 and is fixed with a drive wheel 11.

[0031] Two first arc-shaped through slots 9 are respectively opened on the two side plates 3, and are arranged symmetrically front and back. The first arc-shaped through slots 9 are concentric and coaxial with the upper shaft 5.

[0032] Two sliders 8 are slidably connected within two first arc-shaped through slots 9 in a mating connection manner, and are arranged symmetrically front and back. Each slider 8 has a limiting plate 12 fixed on its opposite side, which fits against the side plate 3.

[0033] The limiting plate 12 is provided with a fixing structure for fixing the limiting plate 12 to the side plate 3. The fixing structure includes a hand handle 13 and two second arc-shaped through slots 14. The two second arc-shaped through slots 14 are respectively opened on the two side plates 3 and are arranged symmetrically front and back. The two second arc-shaped through slots 14 correspond to the top of the two first arc-shaped through slots 9. The second arc-shaped through slots 14 and the first arc-shaped through slots 9 are arranged concentrically and coaxially. The top of each of the two limiting plates 12 is fixed with an extension plate 15 that fits against the side plate 3. The hand handle 13 is fixedly connected between the two extension plates 15. The opposite sides of the two extension plates 15 are fixed with screws 16 corresponding to the second arc-shaped through slots 14. The screws 16 slide along the second arc-shaped through slots 14. The end of the screw 16 opposite to the extension plate 15 passes through the second arc-shaped through slots 14 and passes through the side plate 3, and is threadedly connected with a nut 17 that is tightened on the outer wall of the side plate 3.

[0034] The lower shaft 6 is rotatably connected between the two limiting plates 12 via bearings. The front end of the lower shaft 6 passes through the front slider 8 and is fixed with the driven wheel 18. The driven wheel 18 and the driving wheel 11 are connected by a transmission belt.

[0035] The wrinkle-removing roller 7 is located between the two side plates 3 and is fixedly sleeved on the outside of the lower shaft 6. The bottom end of the wrinkle-removing roller 7 extends to the bottom of the side plate 3. The radius of the wrinkle-removing roller 7 is greater than the height difference between the two ends of the first arc-shaped through groove 9 (that is, when the wrinkle-removing roller 7 moves to the highest point, its bottom end still extends to the bottom of the side plate 3).

[0036] The gears 10 in the two wrinkle-removing roller 7 assemblies mesh with each other. A fixing plate 32 is fixed to the bottom end of the first mounting plate 4, and a first motor 33 for driving one of the gears 10 to rotate is mounted on the fixing plate 32.

[0037] The lower support includes a base plate 19, a support plate 20, and a lifting assembly. A second mounting plate (not shown) for fixed connection to an external device is fixed to the rear side of the base plate 19. The support plate 20 is located above the base plate 19 and directly below the two wrinkle-removing components. The lifting assembly is connected between the base plate 19 and the support plate 20 and is used to move the support plate 20 up and down.

[0038] The lifting assembly includes an upper guide rail assembly, a lower guide rail assembly, an X-shaped bracket, and a second motor 21. The upper guide rail assembly includes an upper guide rod 22, two upper fixed blocks 23, and two upper sliding blocks 24. The two upper fixed blocks 23 are fixed to the bottom of the support plate 20 and are symmetrically arranged. The upper guide rod 22 is fixedly connected between the two upper fixed blocks 23 and extends laterally. The two upper sliding blocks 24 are slidably fitted onto the outside of the upper guide rod 22. The lower guide rail assembly includes a lower guide rod 25, a threaded rod 26, two lower fixed blocks 27, and two lower sliding blocks 28. The two lower fixed blocks 27 are fixed to the top of the base plate 19 and are symmetrically arranged. The lower guide rod 25 is fixedly connected between the two lower fixed blocks 27 and extends laterally. The threaded rod 26 is rotatably connected between the two lower fixed blocks 27 via bearings, and its extension direction is consistent with that of the lower guide rod 25. Both sliding blocks 28 are slidably sleeved on the outside of the lower guide rod 25, and are respectively threaded onto the positive and negative threaded portions of the positive and negative threaded rods 26. A second motor 21 is mounted on one of the lower fixed blocks 27 to drive the positive and negative threaded rods 26 to rotate. The X-shaped bracket consists of two connecting rods 29. The middle positions of the two connecting rods 29 are rotatably connected by a pin. The top ends of the two connecting rods 29 are rotatably connected to the two upper sliding blocks 24 by pins. The bottom ends of the two connecting rods 29 are rotatably connected to the two sliding blocks 28 by pins. A buffer plate 30 is provided at the top of the support plate 20, and several buffer springs 31 are connected between the buffer plate 30 and the support plate 20.

[0039] Working principle:

[0040] After placing the fabric on top of the buffer plate 30, adjust the position of the wrinkle-removing rollers 7 according to the width of the fabric, so that the bottom ends of both wrinkle-removing rollers 7 correspond to the edges of the fabric. Then, the lifting assembly moves the support plate 20 upwards. The upward movement of the support plate 20 moves the buffer plate 30 upwards. The buffer plate 30 moves the fabric upwards until it is pressed between the support plate 20 and the two wrinkle-removing rollers 7. At this point, the buffer plate 30 will move downwards relative to the support plate 20. The buffer spring 31 is pressed, creating a cushioning effect. By observing the movement of the buffer plate 30 relative to the support plate 20, the operator can quickly determine whether the buffer plate 30 and the wrinkle-removing rollers 7 are pressed tightly, thus ensuring that the wrinkle-removing rollers 7 apply sufficient and appropriate pressure to the fabric. This appropriate pressure ensures that the wrinkle-removing rollers 7 can fully flatten the fabric without affecting its movement.

[0041] Then, the first motor 33 is started, which drives the gear 10 connected to it to rotate. The gear 10 drives the upper shaft 5 to rotate. The upper shaft 5 drives the driving wheel 11 to rotate. The driving wheel 11 drives the driven wheel 18 to rotate. The driven wheel 18 drives the lower shaft 6 to rotate. The lower shaft 6 drives the wrinkle-removing roller 7 to rotate. At the same time, because the two gears 10 are meshed with each other, the other gear 10 will rotate synchronously in the opposite direction, thereby driving the other wrinkle-removing roller 7 to rotate synchronously in the opposite direction.

[0042] The process of adjusting the position of the wrinkle-removing roller 7 is as follows: First, loosen the nut 17, allowing the screw 16 to slide freely in the second arc-shaped groove 14. The limiting plate 12 is no longer fixed to the side plate 3, and the slider 8 can also slide freely in the first arc-shaped groove 9. Then, move the extension plate 15 by holding the lever 13. The extension plate 15 drives the screw 16 to slide along the second arc-shaped groove 14, and at the same time, the extension plate 15 drives the limiting plate 12 to move. The limiting plate 12 drives the slider 8 to slide in the first arc-shaped groove 9. Since the first arc-shaped groove 9 is concentric and coaxial with the upper shaft 5, the distance between the axes of the driven wheel 18 and the driving wheel 11 remains constant regardless of the position of the slider 8. The transmission belt between the driven wheel 18 and the driving wheel 11 can also always remain taut, and the driven wheel 18 and the driving wheel 11 can always be in a transmission connection relationship through the transmission belt.

[0043] After the wrinkle-removing roller 7 is positioned correctly, tighten the nut 17 to fix the limiting plate 12 onto the side plate 3. The limiting plate 12 cannot move, thus fixing the position of the slider 8 and the wrinkle-removing roller 7. During the movement of the wrinkle-removing roller 7, its position changes not only in the left-right lateral direction but also at its height. Because the bottom end of the wrinkle-removing roller 7 extends below the side plate 3, the radius of the wrinkle-removing roller 7 is greater than the height difference between the two ends of the first arc-shaped through groove 9. Therefore, regardless of the height of the wrinkle-removing roller 7, its bottom end will always extend below the side plate 3.

[0044] The lifting assembly operates as follows: The second motor 21 is activated. The second motor 21 drives the forward and reverse threaded rods 26 to rotate. The forward and reverse threaded rods 26 drive the two sliding blocks 28 on them to move in opposite directions along the forward and reverse threaded rods 26 and the lower guide rod 25. The two sliding blocks 28 drive the X-shaped bracket to fold or unfold. The X-shaped bracket drives the two upper sliding blocks 24 to move in opposite directions along the upper guide rod 22, and simultaneously drives the two upper sliding blocks 24 to move up and down. The upper sliding blocks 24 drive the support to move up and down.

[0045] This invention can adjust the spacing between the two wrinkle-removing rollers 7 according to the width of the fabric, thereby expanding its applicability and ensuring that fabrics of different widths can be fully flattened.
