Technical Field

[0001] This utility model relates to the technical field of fabric folding devices, and in particular to a fabric folding device and a fabric processing system. Background Technology

[0002] Folding is a widely used step in fabric processing. It plays a crucial role in fabric dyeing and finishing, ensuring that dyes or finishing agents evenly cover the entire fabric surface, or ensuring consistency in processing positions during other steps. Whether in garment manufacturing, where pre-treatment processes like ironing and setting are required, or in home textile manufacturing, where large areas of fabric are processed, folding or turning is an essential step. Folding the fabric to be processed improves the quality and consistency of the fabric or finished product, and ensures that the final product meets the expected technical requirements and aesthetic standards.

[0003] In existing technologies, folding or turning fabrics is usually accomplished using mechanical devices. Fabric turning machines typically consist of a frame, a turning device, a conventional system, and a control system. The turning device can be a roller type or a flipping plate type, etc. However, the structure of existing fabric turning equipment is relatively fixed, resulting in low accuracy when turning different types or sizes of fabrics.

[0005] In a first aspect, a fabric folding device is provided, comprising:

[0006] A fabric tensioning assembly includes a tensioning member and a first driving member, wherein the tensioning member is fixedly connected to the first driving member, and the first driving member is used to drive the tensioning member to move in order to tension the fabric to be folded.

[0007] A fabric positioning assembly includes a positioning element and a second driving element. The positioning element is disposed opposite to the tensioning element, and the second driving element is used to drive the positioning element to move.

[0008] A folding assembly includes a folding component and a third driving component. The folding component is rotatably mounted on one end of the third driving component. The folding component is used to hook the edge of the fabric to be folded and fold the fabric. The third driving component is used to drive the folding component to extend, retract, and rotate.

[0009] In one embodiment, the tensioning member includes at least two parallel movable guide rods, and the first driving member includes a first translation component. The movable guide rods are connected to the translation component, and the translation component is used to drive the movable guide rods to move in a direction perpendicular to the movable guide rods.

[0010] In one embodiment, the fabric tensioning assembly further includes a first fixing member, and the first driving member includes a belt drive mechanism. The belt drive mechanism includes a fixed belt seat, a movable belt seat, and a drive belt sleeved on the fixed belt seat and the movable belt seat. The fixed belt seat is mounted on the first fixing member, and the movable belt seat is movably mounted on the first fixing member.

[0011] In one embodiment, the fabric tensioning assembly further includes a second driving member connected to the first fixing member, the second driving member being used to drive the first fixing member to move along the extension direction of the movable guide rod.

[0012] In one embodiment, the positioning element includes a fixed guide rod, and the contact surface between the fixed guide rod and the movable guide rod is a plane.

[0013] In one embodiment, the folding member includes a telescopic rod, a hook, and a stop. The hook is rotatably connected to one end of the telescopic rod, and the stop is fixedly connected to the hook. The stop is used to limit the rotation angle of the hook.

[0029] See Figure 1 Figure 1 shows a schematic diagram of the fabric turning device according to an embodiment of the present invention. The fabric turning device provided in an embodiment of the present invention includes:

[0030] A fabric tensioning assembly includes a tensioning member and a first driving member. The tensioning member is fixedly connected to the first driving member, and the first driving member is used to drive the tensioning member to move to tension the fabric to be folded.

[0031] The fabric positioning assembly includes a positioning element and a second driving element. The positioning element is disposed opposite to a tensioning element, and the second driving element is used to drive the positioning element to move.

[0032] The folding assembly includes a folding component and a third drive component. The folding component is rotatably mounted on one end of the third drive component. The folding component is used to hook the edge of the fabric to be folded and fold the fabric. The third drive component is used to drive the folding component to extend, retract, and rotate.

[0033] The fabric tensioning assembly refers to a collection of components used to tension fabric to be folded. The fabric to be folded refers to the fabric that needs to be folded or turned over for subsequent processing. It can be unprocessed sheet fabric or fabric that has already undergone previous processing and has a specific shape, such as tubular or bag-shaped fabric. The specific structure of the fabric tensioning assembly can vary depending on the fabric to be folded. For example, when the fabric to be folded is sheet-shaped, the fabric tensioning assembly can have one or more clamping mechanisms. The clamping mechanisms can clamp the edges of the fabric and apply tension in a specific direction to tension the fabric. A first driving member is used to drive the clamping mechanisms to move and tension the fabric to be folded. When the fabric to be folded is tubular, the fabric tensioning assembly can have a mechanism that can extend into the tubular structure and expand the tubular structure outward to achieve fabric tension, such as a fabric tensioning frame. The first driving member is used to drive the fabric tensioning frame and other mechanisms to move and tension the fabric to be folded. A fabric positioning component is a component used to position the fabric to be folded, ensuring the consistency of the folding position or size of multiple pieces of fabric being folded continuously, thereby improving the accuracy of the folding operation. The folding component is used to fold or flip the fabric to be folded at a preset angle, size, or position. The folding component may include structures such as a robotic arm. A third driving component is used to drive the folding component to move and complete the folding action. The first, second, and third driving components may include one or more of the following: a motor, hydraulic or pneumatic drive mechanism, gear transmission mechanism, belt drive mechanism, chain drive mechanism, or screw drive mechanism; a transmission mechanism may also be included. The specific structure can be determined based on the specific structure and movement mode of the tensioning component, positioning component, and folding component. The fabric flipping device may also include a controller. The first, second, and third driving components can be electrically connected to the controller. The controller is a unit used to receive signals collected by sensors and control the actions of each driving unit. It can execute pre-set logical instructions and judge and execute corresponding control operations based on sensor signals or user input, such as adjusting the actions of each driving component.

[0034] The aforementioned fabric folding device effectively tensions the fabric to be folded by setting a fabric tensioning component, ensuring the stability and uniformity of the fabric during the folding process. By setting the positioning component and the tensioning component opposite to each other, the fabric can be positioned correctly before folding, reducing positioning errors. The folding component can flexibly hook the edge of the fabric and perform the folding operation. The third driving component drives the folding component to extend, retract, and rotate, enabling the folding component to adapt to fabrics of different sizes and shapes, increasing the applicability and operational flexibility of the device, thereby improving the quality and efficiency of the fabric folding process. The fabric folding device has good adaptability and high precision.

[0035] In one embodiment, the tensioning member includes at least two parallel movable guide rods 9, and the first driving member includes a first translation component. The movable guide rods 9 are connected to the translation component, and the translation component is used to drive the movable guide rods 9 to move in a direction perpendicular to the movable guide rods 9. The movable guide rod 9 refers to a guide rod capable of generating displacement in a preset direction, such as... Figure 1 The extension direction is perpendicular to the movable guide rod 9. Two parallel movable guide rods 9 can extend into the opening of a tubular or bag-shaped fabric and move to both sides to tension the fabric. By adjusting the position of the movable guide rods 9, fabrics of different sizes can be tensioned, or different tension forces can be applied to the fabric. The first translation component may include structures such as a slider, slide rail, lead screw, linear motor, or pulley. The movable component on the translation component is fixedly connected to the movable guide rod 9 and drives the movable guide rod 9 to move and tension the fabric. Two movable guide rods 9 can be provided, or one or more can be provided according to actual needs. Their relative positions are not limited to being parallel to each other; they can also be at a certain angle to adapt to fabrics of different shapes or structures.

[0036] In one embodiment, the fabric tensioning assembly further includes a first fixing member 11, and the first driving member includes a belt drive mechanism. The belt drive mechanism includes a fixed belt seat, a movable belt seat, and a transmission belt sleeved on the fixed belt seat and the movable belt seat. The fixed belt seat is mounted on the first fixing member 11, and the movable belt seat is movably mounted on the first fixing member 11. The first fixing member 11 is used to install the belt drive mechanism and provides necessary mechanical support for the belt drive mechanism and the movable guide rod 9. The fixed belt seat is mounted on one side of the first fixing member 11 and is fixed relative to the first fixing member 11. The movable belt seat is mounted on the side of the first fixing member 11 away from the fixed belt seat and its relative position to the first fixing member 11 is adjustable. The movable belt seat can be positioned using bolts or locating pins. By setting the movable belt seat, not only is the installation of the transmission belt convenient, but the tension of the transmission belt can also be adjusted, or belts of different lengths can be replaced. This allows adjustment of the relative position and movement range of the movable guide rod 9, making the fabric turning device more adaptable. The first fixing member 11 can be as follows: Figure 1 The image shows a fixed plate. A belt drive mechanism is mounted on the first side of the fixed plate, and a belt drive mechanism is mounted on the second side to drive the pulleys on the belt seat to rotate. A first mounting component is provided on the drive belt, which is detachably connected to the drive belt and can move in translational motion under the drive of the drive belt. A movable guide rod 9 seat is detachably mounted on the first mounting component. The movable guide rod 9 seat has a protrusion for mounting the movable guide rod 9. One end of the movable guide rod 9 is cylindrical, and the end opposite to the fixed guide rod 8 is a frustum structure.

[0037] In one embodiment, the fabric tensioning assembly further includes a second driving member connected to the first fixing member 11, the second driving member being used to drive the first fixing member 11 to move along the extending direction of the movable guide rod 9. Figure 1 As shown, the second driving component can be a guide rod sliding cylinder 1212. The piston part of the cylinder is connected to the first fixing component 11. The first fixing component 11 can be driven by the reciprocating motion of the piston to reciprocate along the extension direction of the movable guide rod 9, thereby driving the movable guide rod 9 to move towards the fabric positioning component to achieve fabric positioning.

[0038] In one embodiment, the positioning element includes a fixed guide rod 8, and the contact surface between the fixed guide rod 8 and the movable guide rod 9 is a plane. For example... Figure 1 As shown, the positioning component includes two parallel fixed guide rods 8, which are arranged opposite to the movable guide rod 9. When positioning the fabric, the position of the movable guide rod 9 is adjusted so that it abuts against the fixed guide rod 8, thereby positioning the fabric tensioned on the movable guide rod 9 and facilitating the folding component to fold the fabric.

[0039] In one embodiment, the folding component includes a telescopic rod, a hook 2, and a stop. The hook 2 is rotatably connected to one end of the telescopic rod, and the stop is fixedly connected to the hook 2, limiting the rotation angle of the hook 2. The hook 2 is a component used to hook the edge of the fabric and fold it over. The hook 2 may have the following characteristics: Figure 1 The arc-shaped profile shown is rotatably connected to one end of the telescopic rod, thus stably hooking the edge of the fabric to be folded. Other shapes can also be used depending on actual needs. When the telescopic rod extends, it drives the hook 2 to move to the edge of the fabric to be folded; when it retracts, it drives the hook 2 to fold the fabric according to a preset size. The stop part can be as follows... Figure 1 The stop is positioned above the hook 2 and the telescopic rod to limit the angle at which the hook 2 rotates in a specific direction. When the hook 2 rotates to the maximum allowable angle, the stop can block the hook 2 and stop its rotation, thereby preventing the hook 2 from failing to hook the edge of the fabric and improving the reliability of the fabric folding device.

[0040] In one embodiment, the folding component includes at least two hooks 2, symmetrically arranged on both sides of the tensioning assembly. The at least two hooks 2 can fold the fabric evenly, ensuring consistency in size and position. Figure 1As shown, a belt drive mechanism can be installed on the second fixing member. The belt drive mechanism is driven by the drive motor 6, and a fixed guide rod 8 is installed on the belt drive mechanism. The position of the fixed guide rod 8 can be adjusted by sliding the belt. A telescopic rod, a hook 2, and a stop are installed on the third fixing member. The relative positions of each component can be adjusted by the belt drive mechanism. The third fixing member is connected to the front and rear sliding cylinders 1 of the hook 2. The front and rear sliding cylinders 1 of the hook 2 drive the hook 2 to complete the fabric folding action.

[0041] In one embodiment, the radial dimension of the movable guide rod 9 is less than or equal to the radial dimension of the fixed guide rod 8. Since the positioning of the fabric to be folded is mainly achieved by adjusting the position of the movable guide rod 9 and abutting the end face of the movable guide rod 9 against the end face of the fixed guide rod 8, setting the radial dimension of the movable guide rod 9 to be less than or equal to the radial dimension of the fixed guide rod 8 can facilitate the positioning of the movable guide rod 9 and reduce wear.

[0042] In one embodiment, a suction cup is also included. The suction cup is used to adsorb the fabric to be folded and form an opening to accommodate the movable guide rod 9. One or more suction cups can be provided as needed. The suction cup can be connected to a vacuum pump or vacuum generator via a vacuum pipe to generate negative pressure, creating a pressure difference between the suction cup and the fabric, thereby adsorbing the fabric. When the vacuum is released, the suction cup releases the adsorbed fabric. The suction cup can have an adsorption surface made of flexible materials such as silicone or rubber and a body made of metal or plastic to adapt to the softness and irregularity of the fabric, preventing damage. The suction force of the suction cup can also be controlled by adjusting the vacuum level to adapt to fabrics of different thicknesses and materials.

[0043] Based on the same inventive concept, this application also provides a fabric processing system including the fabric flipping device mentioned above. This system includes the fabric folding device as described in any of the above embodiments. The solution provided by this device is similar to the solution described in the above methods. Therefore, the specific limitations of one or more fabric processing system embodiments provided below can be found in the limitations of the fabric flipping device described above, and will not be repeated here.

[0044] In some embodiments, the fabric processing system may further include components such as a feeding unit, a cutting unit, a sewing unit, an ironing unit, a printing unit, and a coating unit. The feeding unit continuously and evenly conveys the raw fabric to downstream processing equipment. The cutting unit precisely cuts the fabric to the desired shape and size. The sewing unit sews different parts of the fabric together to form a finished or semi-finished product. The ironing unit irons the fabric to make it smoother and flatter. The printing unit prints or dyes the fabric to create patterns or colors. The printing unit may include a screen printer, a digital printer, or a roller printer. The coating unit applies a coating to the fabric surface, giving it specific functions such as water resistance and stain resistance. The fabric turning device in each of the above embodiments can be set upstream or downstream of each of the above units according to processing requirements. For example, it can be set downstream of the feeding unit to fold the fabric conveyed by the feeding unit. Alternatively, fabric turning devices can be set both upstream and downstream of the sewing unit. The upstream fabric turning device is used to turn or fold the fabric to facilitate sewing, while the downstream fabric turning device can fold the fabric sewn into a tubular or bag-shaped form to facilitate subsequent processes.

[0045] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
