Description

Technical Field

[0001] This utility model belongs to the field of fabric processing, and more specifically, it relates to a fabric cutting device. This utility model also relates to a fabric production line. Background Technology

[0002] In the world of textile materials, there are countless types of fibers, each with its own unique physical and chemical properties, which determines that different fibers require different cutting techniques.

[0003] Cotton, linen, and other natural fibers are gifts from nature, possessing excellent breathability and moisture absorption. Due to their relatively loose fiber structure, mechanical blade cutting is an economical and efficient option. Mechanical blade cutting is like a skilled tailor precisely cutting the fabric with a sharp blade, producing clean, smooth cuts. In traditional cotton shirt factories, workers use mechanical blade cutting machines to quickly and consistently cut large pieces of cotton fabric into the required shapes and sizes. Each cut follows a pre-set line precisely, as if drawing a perfect pattern on the fabric. This cutting method is not only low-cost but also does not damage the structure of the natural fibers, thus ensuring product quality. However, with the diversification of application demands, the existing single-material structure of cotton and linen is gradually becoming insufficient. Therefore, some manufacturers print a layer of plastic onto cotton and linen fibers to improve their performance.

[0004] However, existing cutting blades require multiple layers of fabric to be stacked and flattened before cutting, but the existing cutting equipment occupies a large space, requires a large building area in the existing construction site, and cannot meet the requirements for the edge cutting quality of composite fabrics, which urgently needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a fabric cutting device to solve the technical problems of large space occupation, inability to meet the requirements for neatness of fabric edge cutting, and the presence of rough edges in existing fabric processing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a fabric cutting device, comprising: support; A cutting roller is rotatably mounted on the bracket, and the outer periphery of the cutting roller is in close contact with the fabric to be cut; A cutter is oscillatingly mounted on the support, and the oscillation axis of the cutter is parallel to the cutting roller; The drive assembly includes a telescopic cylinder and a swing rod. One end of the swing rod is connected to the cutter, and the other end is swayably mounted on the bracket. The cylinder body of the telescopic cylinder is mounted on the bracket, and the telescopic end of the telescopic cylinder is movably connected to the swing rod. As the telescopic cylinder extends and retracts, the swing rod drives the cutter to press against or move away from the cutting roller.

[0007] In one feasible implementation, the fabric cutting device further includes a traveling mechanism for driving the support to move between different fabric cutting stations; the traveling mechanism includes traveling wheels and a push handle, the traveling wheels being located at the bottom of the support and the push handle being located on one side of the support.

[0008] In one feasible implementation, the traveling mechanism further includes a bogie and a push rod. The traveling wheels include fixed wheels and steering wheels. The fixed wheels are rotatably fixed to the bottom of the support. The bogie is rotatably disposed at the bottom of the support about a vertical axis. The steering wheels are disposed at the bottom of the bogie. One end of the push rod is hinged to the bogie, and the other end is fixedly connected to the push handle. The swing axis of the push rod extends in the horizontal direction.

[0009] In one feasible implementation, the cutter is disc-shaped and rotatably mounted on the swing arm about its own axis.

[0010] In one feasible implementation, the telescopic cylinder is a telescopic air cylinder, and the cylinder body of the telescopic air cylinder is fixedly connected to the bracket.

[0011] In one feasible implementation, the drive assembly further includes a connecting rod and a mounting plate, wherein the top end of the connecting rod is connected to the mounting plate and the bottom end is threadedly connected to the cylinder body of the telescopic cylinder; The top crossbeam of the bracket is located between the mounting plate and the cylinder body of the telescopic cylinder, and the bottom end of the connecting rod extends downward and is hinged to the swing rod.

[0012] In one feasible implementation, the outer periphery of the cutting roller is provided with a cutting groove, which is adapted to the rolling motion of the cutter.

[0013] In one feasible implementation, the fabric cutting device further includes a roll roller rotatably disposed on the support, and the roll roller is parallel to the cutting roller.

[0014] Compared with existing technologies, the advantages of the fabric cutting device provided by this utility model are as follows: Firstly, in the specific implementation process of the above embodiment, the telescopic cylinder drives the swing rod to swing around its hinge point, thereby driving the cutter connected to it to perform a swinging action with its swing axis as the center, cutting close to the cutting roller or stopping cutting away from the cutting roller. In this way, by using the rotation setting of the cutting roller to transport and support the fabric, and cooperating with the swinging cutter and drive assembly, the cutter achieves precise and efficient swinging cutting of the fabric, achieving the technical effects of automated cutting, reducing manual labor intensity, and improving cutting efficiency and consistency. This helps to solve the technical problems of low efficiency, poor accuracy and high labor intensity of traditional manual cutting or fixed cutting methods.

[0015] Secondly, by setting up a walking mechanism, when the operator swings the push handle, the push handle drives the push rod to move, and the push rod pulls the bogie to rotate around the vertical axis, thereby changing the direction of the steering wheel installed at the bottom of the bogie. In conjunction with the fixed wheel, it realizes the flexible steering of the device, realizes convenient steering during the movement of the cutting device, enhances the flexibility of equipment movement, and facilitates the adjustment of position in the production line or work area.

[0016] Furthermore, for the traveling mechanism, when the operator swings the push handle, the push handle drives the push rod to move, and the push rod pulls the bogie to rotate around the vertical axis, thereby changing the direction of the steering wheel installed at the bottom of the bogie (and working together with the fixed wheel to achieve flexible steering of the device). This realizes convenient steering and precise control during the movement of the cutting device, and achieves the technical effect of enhancing the flexibility of equipment movement and facilitating the adjustment of position in the production line or work area. This helps to solve the technical problems of equipment movement direction being singular, difficulty in steering in narrow spaces, and inconvenience in adjustment.

[0017] Furthermore, the above embodiment uses a telescopic cylinder as the telescopic cylinder and is fixedly connected to the bracket. The bottom end of the connecting rod is threaded to the cylinder body, and the top end is clamped and fixed to the bracket beam through the mounting plate. At the same time, the bottom end of the connecting rod extends downward and is hinged to the swing rod. This not only achieves a stable installation of the cylinder body relative to the bracket, but also provides a hinge point for the transmission of driving force, minimizing the space occupied by the above-mentioned installation part and achieving the technical effect of stable installation and reasonable force distribution.

[0018] Another objective of this invention is to provide a fabric production line, including the fabric cutting device described above.

[0019] Compared with the prior art, the fabric production line of this utility model has all the advantages of the aforementioned fabric cutting device, which will not be elaborated here. At the same time, in the specific implementation process, by setting up the aforementioned fabric cutting device, this utility model realizes the efficient, automated and high-quality operation of the fabric cutting process, improves the automation level of the entire production line, ensures the consistency of cutting quality, increases production efficiency, and reduces labor costs, thereby solving the technical problems of low efficiency and reliance on manual labor in the cutting process of traditional fabric production lines.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] In the description of this utility model, it should be noted that if terms such as "upper", "lower", "inner", "back" or indicating orientation or positional relationship appear, they are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0025] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please refer to the following: Figures 1 to 3 The fabric cutting device provided by this utility model will now be described. This fabric cutting device includes a support 1, a cutting roller 2, a cutter 3, and a drive assembly 4. The support 1 is formed by connecting a crossbeam and a vertical beam. The cutting roller 2 is rotatably mounted on the support 1, with its outer circumference in close contact with the fabric to be cut. The cutter 3 is oscillatingly mounted on the support 1, with its oscillation axis parallel to the cutting roller 2. The drive assembly 4 includes a telescopic cylinder 41 and a swing rod 42. One end of the swing rod 42 is connected to the cutter 3, and the other end is oscillatingly mounted on the support 1. The cylinder body of the telescopic cylinder 41 is mounted on the support 1, and the telescopic end of the telescopic cylinder 41 is movably connected to the swing rod 42. As the telescopic cylinder 41 extends and retracts, the swing rod 42 drives the cutter 3 to move closer to or away from the cutting roller 2.

[0027] Compared with existing technologies, the beneficial effect of the above technical solution is that, in the specific implementation process, the telescopic cylinder 41 drives the swing rod 42 to swing around its hinge point, thereby driving the cutter 3 connected to it to perform a swinging action with its swing axis as the center, cutting close to the cutting roller 2 or stopping cutting away from the cutting roller 2. In this way, through the rotation setting of the cutting roller 2 to transport and support the fabric, and in cooperation with the swinging cutter 3 and the drive component 4, the cutter 3 achieves precise and efficient swinging cutting of the fabric, achieving the technical effects of automated cutting, reducing manual labor intensity, and improving cutting efficiency and consistency. This helps to solve the technical problems of low efficiency, poor accuracy and high labor intensity of traditional manual cutting or fixed cutting methods.

[0028] Furthermore, in the above embodiments, the cutting roller 2 can be a tensioning and transition roller in the fabric cutting and transportation process (this is preferred). During its rotation, only a portion of its outer peripheral surface is in continuous contact with the fabric. This portion of the fabric is pressed by the cutting roller 2, and the cutter 3 can approach or move away from this portion of the outer peripheral surface to cut the fabric located between the cutting roller 2 and the cutter 3. Of course, setting the cutting roller 2 as a roll roller is also an alternative implementation method. In this implementation method, the fabric to be cut is rolled up by the cutting roller 2 in a roll manner. During the rotation of the cutting roller 2, the cutter 3 cuts the multi-layer fabric, which greatly improves the cutting efficiency of the fabric while ensuring a certain cutting accuracy.

[0029] In addition to the above-mentioned feasible implementation methods, in order to facilitate the adjustment of the position of the fabric cutting device between different production lines, in some embodiments, the fabric cutting device further includes a traveling mechanism 6, which is used to drive the support 1 to move between different fabric cutting stations; the traveling mechanism 6 includes a traveling wheel 61 and a push handle, the traveling wheel 61 is located at the bottom of the support 1, and the push handle is located on one side of the support 1.

[0030] In a preferred embodiment, the traveling mechanism 6 further includes a bogie and a push rod. The traveling wheel 61 includes a fixed wheel and a steering wheel 62. The fixed wheel is rotatably fixed to the bottom of the support 1. The bogie is rotatably disposed at the bottom of the support 1 around a vertical axis. The steering wheel 62 is disposed at the bottom of the bogie. One end of the push rod is hinged to the bogie, and the other end is fixedly connected to the push handle. The swing axis of the push rod extends in the horizontal direction. With the above arrangement, when the operator swings the push handle, the push handle drives the push rod to move. The push rod pulls the bogie to rotate around the vertical axis, thereby changing the direction of the steering wheel 62 installed at the bottom of the bogie. Together with the fixed wheel, it realizes the flexible steering of the device, realizes convenient steering during the movement of the cutting device, enhances the mobility of the equipment, and facilitates the adjustment of the position in the production line or work area.

[0031] Based on the above embodiments, in a preferred embodiment, the cutter 3 is disc-shaped and rotatably mounted on the swing rod 42 around its own axis. When the cutter 3 is pressed against the fabric on the cutting roller 2 by the swing rod 42, the disc-shaped cutter 3 can rotate during the cutting process due to the friction with the fabric. The fabric is cut under the pressure of the cutter 3 and the cutting roller 2. The cutting method changes from sliding friction to rolling friction, which achieves the technical effects of reducing cutting resistance, reducing wear of the cutter 3, making cutting more effortless and smooth, and making the cut edge smoother. This solves the technical problems of the cutter 3 being prone to wear due to high frictional resistance, high energy consumption, and the possibility of pulling the fabric and causing uneven cut edges during cutting.

[0032] In a preferred embodiment, the telescopic cylinder 41 is a telescopic air cylinder. The cylinder body of the telescopic air cylinder is fixedly connected to the bracket 1. The fixed cylinder body of the telescopic air cylinder provides a stable reaction force foundation. The linear motion of its telescopic end is reliably converted into the swing of the swing rod 42 through the movable connection point, forming a standardized and rapid response in the driving process.

[0033] In a preferred embodiment, the drive assembly 4 further includes a mounting part, which includes a connecting rod 44 and a mounting plate 43. The top end of the connecting rod 44 is connected to the mounting plate 43, and the bottom end is threadedly connected to the cylinder body of the telescopic cylinder. The top crossbeam of the bracket 1 is located between the mounting plate 43 and the cylinder body of the telescopic cylinder, and the bottom end of the connecting rod 44 extends downward and is hinged to the swing rod 42. In this embodiment, the bottom end of the connecting rod 44 is threadedly connected to the cylinder body, and the top end forms a clamping space with the cylinder body through the mounting plate 43 to clamp and fix the crossbeam of the bracket 1. At the same time, the bottom end of the connecting rod 44 extends downward and is hinged to the swing rod 42, which not only realizes the stable installation of the cylinder body relative to the bracket 1, but also provides a hinge point for the transmission of driving force, so that the telescopic cylinder is stably installed on the bracket 1, the force is reasonable, and it is easy to adjust, maintain and replace.

[0034] In a preferred embodiment, the outer periphery of the cutting roller 2 is provided with a cutting groove 21, which is adapted to the rolling of the cutter 3. When the cutter 3 swings and presses against the cutting roller 2, the cutting edge of the cutter 3 can be precisely embedded and rolled in the cutting groove 21, forming precise guidance and limiting of the cutting position, so as to ensure consistent cutting depth, prevent the fabric from shifting or wrinkling at the cutting point, and protect the cutting edge of the cutter 3 from direct impact with the hard roller surface.

[0035] In a preferred embodiment, the fabric cutting device further includes a roll 5 rotatably mounted on the support 1, and the roll 5 is parallel to the cutting roller 2. The roll 5 is rotatably mounted on the support 1 for receiving or releasing the fabric. It works in conjunction with the cutting roller 2 to tension, convey, and roll up the fabric after cutting. The cutting and receiving / unloading functions are integrated on the same device, which simplifies the operation process, helps to maintain the tension stability of the fabric during the cutting process, improves the automation level of the fabric production line, and solves the technical problems of the existing fabric production process, where the cutting device needs to be used in conjunction with other equipment for receiving or unloading, resulting in cumbersome operation and burrs on the fabric edges.

[0036] In summary, compared with existing technologies, this application achieves efficient, precise, and automated fabric cutting by setting up the above-mentioned structure. The support frame 1 serves as the overall supporting base, upon which the cutting roller 2 rotates and is responsible for supporting and conveying the fabric to be cut. The cutter 3 is oscillating on the support frame 1, its oscillation axis parallel to the cutting roller 2. Through precise control of the drive assembly 4 (including a telescopic cylinder 41 and a swing rod 42)—the telescopic cylinder 41 is fixed to the support frame 1, its telescopic end is movably connected to the swing rod 42, and its other end can swing on the support frame 1, while the swing rod 42 is connected to the cutter 3—the telescopic cylinder 41's telescopic movement drives the swing rod 42 to swing, thereby causing the cutter 3 to perform oscillating movements, either cutting close to the cutting roller 2 or moving away from it to stop cutting. This basic coordinated process completes the automated cutting of the fabric, effectively solving the technical problems of low efficiency, poor precision, and high labor intensity associated with traditional manual or fixed cutting methods, achieving the technical effect of improving cutting efficiency and consistency. The addition of the walking mechanism 6 (including the walking wheels 61 and the push handle) allows the operator to push the device, greatly expanding the working range of a single piece of equipment. The deeper integration of the bogie, push rod, fixed wheels, and steering wheels 62 within the walking mechanism 6 (one end of the push rod is hinged to the bogie, and the other end is fixed to the push handle; the operator swings the push handle, which in turn pulls the bogie to rotate around the vertical axis, thus changing the direction of the steering wheels 62) enables convenient steering and precise positioning control of the equipment, enhancing its flexibility in complex terrain and solving the problems of inconvenient steering and difficult adjustment. Regarding cutting optimization, the design of a disc-shaped cutter 3 rotatably mounted on the swing rod 42 allows the cutter 3 to rotate due to friction during downward cutting, changing the process from sliding friction to rolling friction. This significantly reduces cutting resistance and tool wear, making cutting more effortless and producing a smoother cut, solving the problems of easy wear, high energy consumption, and potential fabric tearing associated with the cutter 3. A cutting groove 21 is opened on the outer periphery of the cutting roller 2 to roll and adapt to the disc cutter 3. This key cooperation allows the cutting edge of the cutter 3 to be precisely embedded and roll in the groove, achieving multiple effects such as accurately guiding the cutting line, maintaining a constant cutting depth, preventing fabric deviation and wrinkles, and protecting the cutting edge. This solves the technical pain points of inconsistent cutting depth and fabric deviation. The drive source adopts a telescopic cylinder and is fixedly connected to the bracket 1, providing a stable, efficient, and fast-responding standardized power output. The reaction force provided by the fixed cylinder body is reliably converted into the swing of the swing rod 42 through the movable connection point, solving the problems of high cost and difficult maintenance of complex drive sources. The cooperation of the mounting part (connecting rod 44 and mounting plate 43) through threaded connection and clamping fixation (connecting rod 44 connects the cylinder body and mounting plate 43, and fixes the crossbeam of bracket 1 in between, with the bottom end extending and hinged to the swing rod 42) realizes the modular, stable and adjustable installation of the cylinder, which is conducive to maintenance and replacement, and solves the drawbacks of unstable installation and cumbersome disassembly of the drive component 4.In addition, the addition of a roll-up roller 5 and a cutting roller 2, which are set in parallel, enables the collection and release of the fabric and maintains the stability of the tension during cutting. It integrates the functions of taking in and releasing the material, simplifies the operation process, improves the degree of automation, and solves the problems of needing additional equipment, cumbersome operation and difficulty in controlling tension.

[0037] Another objective of this invention is to provide a fabric production line, including the fabric cutting device described above.

[0038] Compared to existing technologies, the fabric production line of this utility model possesses all the advantages of the aforementioned fabric cutting device, which will not be elaborated upon here. At the same time, by integrating the aforementioned device into the fabric production line, and through the systematic and efficient cooperation between various components, continuous automated operation is achieved from fabric conveying and precise length cutting to winding. This results in significant technical effects such as improving the automation level of the entire line, ensuring consistent cutting quality, greatly increasing production efficiency, and reducing overall costs. It fundamentally helps to solve a series of technical problems in traditional fabric production lines, such as low efficiency in the cutting process, reliance on manual labor for precision, and the tendency for the cutting process to become a production bottleneck.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
