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 are inadequate for cutting cotton-linen-plastic composite materials due to the varying elasticity of different fabrics. Furthermore, because cotton and linen are highly absorbent, their cutting performance changes in high-humidity environments, requiring adjustments to the cutting depth based on the specific cutting scenario. Additionally, existing cutting blades typically use cylinders and linkages for fixing, making blade adjustment inconvenient and unable to meet the cutting needs of various fabrics, thus necessitating improvements. Utility Model Content

[0005] The purpose of this invention is to provide a fabric cutting device to solve the technical problem that existing fabric cutting devices cannot be used to cut fabrics with different elasticities.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a fabric cutting device, comprising: Support frame; The loading and unloading mechanism includes a tension roller, a cutting roller, and a winding roller arranged sequentially along the processing path of the fabric on the support frame, wherein the tension roller, the cutting roller, and the winding roller are parallel to each other; A cutting mechanism includes a mounting frame and a cutter. The mounting frame includes a mounting body and a mounting handle. The mounting body is movably mounted on the support frame in a vertical direction and a first horizontal direction. The mounting body has a mounting hole extending in a second horizontal direction, which is perpendicular to the first horizontal direction and perpendicular to the axial direction of the cutting roller. The mounting handle is lockably inserted into the mounting hole to move closer to or further away from the cutting roller. The cutter is rotatably mounted on the mounting handle, and the rotation axis of the cutter extends in the first horizontal direction.

[0007] In one feasible implementation, the support frame includes a frame body and a guide rail disposed on the frame body, the guide rail extending axially along the cutting roller, and the mounting body being lockably adapted to the guide rail along the length direction of the guide rail.

[0008] In one feasible implementation, the mounting bracket further includes a first locking bolt screwed to the mounting body, the first locking bolt abutting against the mounting handle located in the mounting hole.

[0009] In one feasible implementation, the mounting bracket further includes a second locking bolt that is threadedly adapted to the mounting body, the second locking bolt being able to abut against the guide rail.

[0010] In one feasible implementation, the mounting bracket has a dovetail-shaped groove at the bottom and a dovetail-shaped protrusion at the top of the guide rail. The length of the protrusion extends along the length of the guide rail, and the groove and the protrusion engage and are guided and adapted.

[0011] In one feasible implementation, the tension roller is movably mounted on the frame body. The support frame further includes a fixed block and a lifting screw mounted on the frame body. The frame body is provided with a guide groove that guides the vertical movement of the fixed block. The lifting screw is threadedly adapted to the frame body and extends in the vertical direction. One end of the lifting screw located in the guide groove is rotatably adapted to the fixed block. The fixed block and the tension roller are rotatably engaged. As the lifting screw rotates, the tension roller moves vertically.

[0012] In one feasible implementation, the support frame has an elongated hole, and the guide rail is provided on the support frame through the elongated hole in an adjustable manner.

[0013] In one feasible implementation, the loading and unloading mechanism further includes a clamping roller disposed on the support frame, the clamping roller being located below the tensioning roller and parallel to the tensioning roller.

[0014] Compared to existing technologies, the beneficial effects of the fabric cutting equipment provided by this utility model are as follows: In the specific implementation process, this utility model utilizes the cooperation of a support frame, a loading and unloading mechanism, and a cutting mechanism. The cutting mechanism achieves multi-dimensional positioning by moving the mounting body along the vertical and horizontal directions and the first horizontal direction on the support frame. The mounting handle, through its insertion into the mounting hole in the second horizontal direction and its lockable adjustment, achieves precise control of the distance between the cutter and the cutting roller. Simultaneously, the cutter can rotate around the axis of the first horizontal direction, allowing the cutting angle to adapt to the fabric characteristics. This structure realizes continuous coordination of the tensioning, cutting, and rolling processes in the fabric processing path, thereby enabling more precise cutting of taut fabrics, improving cutting accuracy and adaptability. It helps solve the technical problems of fabric waste and low processing efficiency caused by the fixed cutting position and easy fabric movement during the cutting process in traditional equipment.

[0015] Secondly, the mounting body slides along the length of the guide rail (axial direction of the cutting roller) and can be fixed by a locking mechanism, achieving precise positioning of the cutter in the direction of the roller axis. This structure allows the cutting mechanism to cover the full width of the fabric, achieving the technical effect of flexibly adjusting the cutting trajectory, which helps to solve the problem of low efficiency caused by narrow-width equipment requiring multiple adjustments to complete the processing of wide-width fabrics.

[0016] Furthermore, in this application, through the threaded transmission between the aforementioned lifting screw and the frame body, the screw rotation drives the fixed block to move vertically along the guide groove, thereby causing the tension roller to rise and fall synchronously. This structure achieves stepless adjustment of fabric tension, adapting to the pre-tensioning requirements of different fabrics and helping to solve the problem of wrinkling or deformation during cutting caused by improper tension.

[0017] Furthermore, this invention utilizes the bolt connection between the elongated hole and the guide rail. Loosening the bolt allows the guide rail to move up and down along the hole, and then re-locking it after adjustment. This enables adaptive adjustment of the overall height of the cutting mechanism, facilitating the matching of cutting depths for fabrics of different thicknesses. It also makes it convenient to adjust the height of the entire cutting mechanism during maintenance, solving cutting problems or maintenance inconveniences caused by fixed height limitations.

[0018] Furthermore, in the aforementioned implementation, the parallel opposing cooperation of the clamping roller and the tensioning roller creates a frictional grip as the fabric passes between them, working in conjunction with the tensioning roller to provide bidirectional constraint. This structure achieves stable traction of the fabric before it enters the cutting area, preventing fabric deviation and effectively addressing the positioning error problem caused by slack in flexible fabrics during processing.

[0019] Another objective of this invention is to provide a fabric production line, which includes the fabric cutting equipment described above.

[0020] Compared with the prior art, the fabric production line of this utility model has all the advantages of the aforementioned fabric cutting equipment, which will not be elaborated here. Attached Figure Description

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.

[0026] 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.

[0027] Existing cutting blades, when cutting fabrics (especially composite fabrics), cannot handle different types of fabrics due to the significant differences in elasticity. Furthermore, existing cutting blades are typically fixed using cylinders and linkages, making blade adjustment inconvenient. Consequently, existing cutting blades cannot cope with different types of elastic fabrics and cannot meet the cutting needs of various fabrics.

[0028] To address the aforementioned issues, this application improves existing fabric cutting equipment by installing a cutting mechanism 3 and a cutting roller 22 on the fabric winding and unwinding mechanism to cut the fabric during the conveying process.

[0029] Based on the above design concept, please refer to the following: Figures 1 to 3 The fabric cutting equipment provided by this utility model will now be described. The fabric cutting equipment includes a support frame 1, a loading and unloading mechanism 2, and a cutting mechanism 3. The loading and unloading mechanism 2 includes a tension roller 21, a cutting roller 22, and a winding roller 23 arranged sequentially along the processing path of the fabric on the support frame 1. The tension roller 21, the cutting roller 22, and the winding roller 23 are parallel to each other. The cutting mechanism 3 includes a mounting frame 31 and a cutter 32. The mounting frame 31 includes a mounting body 311 and a mounting handle 312. The mounting body 311 is movably mounted on the support frame 1 in the vertical direction and the first horizontal direction. The mounting body 311 has a mounting hole extending in the second horizontal direction, which is perpendicular to the first horizontal direction and perpendicular to the axial direction of the cutting roller 22. The mounting handle 312 is lockably inserted into the mounting hole to move closer to or away from the cutting roller 22. The cutter 32 is rotatably mounted on the mounting handle 312, and the rotation axis of the cutter 32 extends in the first horizontal direction.

[0030] In the specific implementation of the above embodiments, the cutting mechanism 3 achieves multi-dimensional positioning by moving the mounting body 311 along the vertical and first horizontal directions on the support frame 1. The mounting handle 312, through its insertion into the mounting hole in the second horizontal direction and its lockable adjustment, achieves precise control of the distance between the cutter 32 and the cutting roller 22. Simultaneously, the cutter 32 can rotate around the axis of the first horizontal direction, allowing the cutting angle to adapt to the fabric characteristics. This structure achieves continuous coordination of the tensioning, cutting, and rolling processes in the fabric processing path, thereby enabling more precise cutting of taut fabrics, improving cutting accuracy and adaptability. This helps solve the technical problems of fabric waste and low processing efficiency caused by the fixed cutting position and easy fabric movement during the cutting process in traditional equipment.

[0031] In one feasible implementation, the support frame 1 includes a frame body 11 and a guide rail 12 disposed on the frame body 11. The guide rail 12 extends axially along the cutting roller 22, and the mounting body 311 is lockably adapted to the guide rail 12 along its length. More preferably, the mounting frame 31 further includes a second locking bolt 34 threadedly adapted to the mounting body 311, which abuts against the guide rail 12. With this configuration, the mounting body 311 can slide along the length of the guide rail 12 and can be locked to the guide rail 12 by the locking bolt. This allows the cutting mechanism 3 to cover the full width of the fabric, flexibly adjusting the cutting width and solving the inefficiency problem caused by narrow-width equipment requiring multiple adjustments to complete the processing of wide-width fabrics. Simultaneously, through the threaded engagement of the second locking bolt 34 with the mounting body 311, the bolt abuts against the side of the guide rail 12 when screwed in, locking the position of the mounting body 311 through friction. This structure works in conjunction with the guiding function of the guide rail 12 to enable the cutting mechanism 3 to be fixed at any position during movement, thus precisely controlling the cutting path.

[0032] Based on the above embodiments, in one feasible implementation, the mounting bracket 31 further includes a first locking bolt 33 screwed to the mounting body 311. The first locking bolt 33 can abut against the mounting handle 312 located in the mounting hole. When the bolt is screwed in, it abuts against the outer wall of the mounting handle 312, forming a mechanical locking force to prevent the mounting handle 312 from shifting under cutting vibration.

[0033] In one feasible implementation, the mounting bracket 31 has a dovetail-shaped groove at its bottom, and the guide rail 12 has a dovetail-shaped protrusion at its top, extending along the length of the guide rail 12. The groove and the protrusion engage and are guided together. The nested fit between the dovetail-shaped groove and the protrusion creates a surface contact constraint when the groove slides along the protrusion's track, preventing lateral dislocation. This forms a highly rigid guiding connection between the mounting bracket 31 and the guide rail 12, ensuring smooth movement even when bearing cutting reaction forces.

[0034] In a more preferred embodiment, the tension roller 21 is movably mounted on the frame body 11. The support frame 1 also includes a fixed block 13 and a lifting screw 14 mounted on the frame body 11. The frame body 11 is provided with a guide groove 110 that guides the vertical movement of the fixed block 13. The lifting screw 14 is threadedly fitted to the frame body 11 and extends vertically. One end of the lifting screw 14 located in the guide groove 110 is rotatably fitted to the fixed block 13. The fixed block 13 rotates in conjunction with the tension roller 21. As the lifting screw 14 rotates, the tension roller 21 moves vertically. With this configuration, in this embodiment, through the threaded transmission between the lifting screw 14 and the frame body 11, the screw rotation pushes the fixed block 13 to move vertically along the guide groove 110, causing the tension roller 21 to rise and fall synchronously. This structure achieves stepless adjustment of fabric tension, adapting to the pre-tensioning requirements of different fabrics, and helps solve the problem of wrinkling or deformation during cutting caused by improper tension.

[0035] In one feasible implementation, the support frame 1 has an elongated hole, through which a guide rail 12 is vertically adjustable. The guide rail 12 can be moved up and down along the hole after the bolts are loosened, and then re-locked after adjustment. This allows for adaptive adjustment of the overall height of the cutting mechanism 3, facilitating the matching of cutting depths for fabrics of different thicknesses. It also facilitates adjustment of the overall height of the cutting mechanism 3 during maintenance, resolving cutting problems or maintenance inconveniences caused by fixed height limitations.

[0036] In addition to the above-described embodiments, in one feasible implementation, the loading and unloading mechanism 2 further includes a clamping roller 24 disposed on the support frame 1. The clamping roller 24 is located below the tension roller 21 and parallel to the tension roller 21. The parallel opposing cooperation between the clamping roller 24 and the tension roller 21 creates a frictional grip when the fabric passes between the two rollers, and the clamping roller 24, together with the tension roller 21, provides bidirectional constraint. This creates stable traction for the fabric before it enters the cutting area, preventing the fabric from deviating, thereby solving the problem of positioning errors caused by slack in the processing path of flexible fabric and improving cutting accuracy.

[0037] Based on the same inventive concept, this utility model also proposes a fabric production line, which includes the fabric cutting equipment mentioned above.

[0038] Compared with the prior art, the fabric production line of this utility model has all the advantages of the aforementioned fabric cutting equipment, which will not be elaborated here. At the same time, through the integrated application of the aforementioned fabric cutting equipment in the production line, its high-precision cutting and adaptive adjustment functions form a continuous process with other process equipment (such as printing and sewing equipment), realizing efficient processing of fabric from raw materials to finished products, improving the overall production automation level and helping to solve the problem of limited production capacity caused by bottlenecks in the cutting process in multi-equipment collaborative production.

[0039] In summary, the fabric cutting equipment of this application achieves efficient and precise fabric processing through the coordinated operation of the support frame 1, the loading and unloading mechanism 2, and the cutting mechanism 3. The tension roller 21, the cutting roller 22, and the winding roller 23 are arranged sequentially along the processing path, forming a continuous fabric cutting, conveying, and winding system. The cutting mechanism 3, through the movable design of the mounting body 311 on the support frame 1 along the vertical and first horizontal directions, combined with the mounting handle 312 which can be locked into the mounting hole in the second horizontal direction, allows for flexible adjustment of the distance between the cutter 32 and the cutting roller 22. Simultaneously, the cutter 32 can rotate around the first horizontal axis, effectively adapting to different cutting size requirements. The guiding cooperation between the guide rail 12 and the mounting body 311 ensures the precise movement and positioning of the cutter 32 along the axial direction of the cutting roller 22. The first locking bolt 33 and the second locking bolt 34 are used to fasten the mounting handle 312 and the guide rail 12 respectively, ensuring the stability of the cutting process. The nested structure of the dovetail groove and the protrusion enhances the rigidity and vibration resistance of the moving parts. The tension roller 21 is vertically adjustable via the lifting screw 14 and guide groove 110, facilitating precise control of fabric tension. The clamping roller 24 works in conjunction with the tension roller 21 to prevent fabric deviation. The guide rail 12 is height-adjustable via an elongated hole to accommodate different fabric thicknesses. When integrated into the production line, the entire system enables high-precision, adaptive continuous cutting, effectively solving problems such as fabric waste, low processing efficiency, and unstable product quality caused by fixed cutting positions, non-adjustable angles, and inconvenient tension control in traditional equipment. This significantly improves production automation and processing efficiency.

[0040] 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.
