Description

Technical Field

[0001] This utility model relates to the field of sofa manufacturing technology, specifically to a fabric cutting device for sofa manufacturing. Background Technology

[0002] A sofa is a piece of furniture used for sitting, lying down, resting, or leaning against. The structure of a sofa typically consists of several parts, including the frame, filling, and fabric. The frame, as the core supporting structure, determines the sofa's stability and durability. It not only needs to withstand daily use and weight but also ensure that the sofa is not easily damaged or deformed during use, thus extending its lifespan. The filling determines the sofa's resilience and softness, providing great comfort and relaxation. The fabric is key to the sofa's appearance and feel. Different fabric materials, colors, and patterns give sofas unique styles and textures. Furthermore, the fabric should have good wear resistance, stain resistance, and breathability to ensure the sofa remains comfortable and clean during use. The manufacturing process for a sofa begins with making the frame, then covering it with a sturdy, breathable mesh fabric to house the filling. Next, the fabric is cut according to the sofa's size and style, and then sewn to wrap around the frame, ultimately creating a beautiful and practical sofa.

[0003] For fabric cutting, the large width of purchased fabric rolls often makes the cutting process extremely tedious and complex. Therefore, before cutting the fabric, it needs to be slit using cutting equipment. This process involves moving a cutter via a telescopic cylinder to cut the fabric into multiple strips. However, cutting equipment equipped with only a single cutter has a limited number of strips, making it difficult to cut multiple strips simultaneously. While cutting equipment with multiple cutters can cut multiple strips simultaneously, controlling multiple telescopic cylinders to move the cutters is very cumbersome in practice. To reduce the complexity of operating multiple cutters, a common practice is to use a cutter holder with multiple cutters, moving the holder synchronously via a telescopic cylinder to simplify the cutting process. However, this method lacks flexibility in adjusting the number of strips, meaning that in actual production, the number of fabric strips cut still cannot fully meet diverse needs. Therefore, there are still shortcomings in fabric cutting and slitting. It is necessary to improve the fabric cutting device to make it easier to operate and to provide a variety of cutting methods to meet the cutting needs of the fabric, thereby improving the efficiency and quality of the entire production process. Summary of the Invention

[0004] In view of the shortcomings of the prior art, this utility model provides a fabric cutting device for sofa production that is easy to operate and can provide a variety of cutting methods, in order to overcome the defects in the prior art.

[0005] The technical solution adopted by this utility model is as follows: a fabric cutting device for sofa production, including a frame, a horizontally arranged fixed plate on the frame, and a cutter arranged above the fixed plate. A fixed column is horizontally arranged above the fixed plate. The fixed column and the fixed plate are respectively installed on the frame. Several fixed sleeves are arranged on the fixed column. A fixed seat, a cutting seat, and two fixed rings are respectively fitted on the fixed sleeves. The cutter is installed on the bottom end of the cutting seat. The two fixed rings are respectively installed on both sides of the fixed sleeve. The fixed rings and the fixed seat are located between the two fixed rings. The inner sides of the two fixed rings are in contact with the fixed seat and the cutting seat, respectively. A first telescopic cylinder is arranged between the fixed seat and the cutting seat. The two ends of the first telescopic cylinder are respectively hinged to the fixed seat and the cutting seat. A fixed rod is arranged above the fixed column. A fixed groove is opened on the fixed seat. The fixed groove is fitted onto the fixed rod. A second telescopic cylinder is arranged at both ends of the fixed rod. The telescopic direction of the second telescopic cylinder is perpendicular to the axial direction of the fixed column. The fixed rod is installed on the frame through the second telescopic cylinder.

[0006] Preferably, one of the fixing sleeves is installed in the middle of the fixing column, and the remaining fixing sleeves are movably fitted onto the fixing column. An adjusting mechanism is provided on the side of the fixing sleeve away from the first telescopic cylinder. The adjusting mechanism includes several linkage groups and a third telescopic cylinder provided on the side of the linkage group away from the fixing sleeve. The linkage group includes two linkages of the same length, with the middle of the two linkages hinged to each other. The end of the linkage is hinged to the end of the linkage of an adjacent linkage group. The middle of one linkage is connected to a fixing ring on one side of the fixing sleeve. The two ends of the third telescopic cylinder are respectively connected to the two linkage groups.

[0007] Preferably, a fixing strip is provided between the connecting rod assembly and the fixing column. The axial direction of the fixing strip is parallel to the axial direction of the fixing column. The fixing strip is installed on the side wall of the fixing column. A through groove is provided on the fixing sleeve. The through groove is opened on the inner wall of the fixing sleeve and extends from one end of the fixing sleeve to the other end of the fixing sleeve. The through groove is movably fitted onto the fixing strip. The cross-sectional shape of the through groove matches the cross-sectional shape of the fixing strip.

[0008] Preferably, the frame is provided with two first rollers, which are located on both sides of the fixed plate. One end of the first roller is provided with a first bearing seat, which is rotatably mounted on the first bearing seat. The other end of the first roller is provided with a motor, which is connected to the drive end of the motor. Both the motor and the first bearing seat are mounted on the frame. A second roller is provided above the first roller. The two ends of the second roller are respectively provided with fourth telescopic cylinders along the vertical direction. The telescopic rod of the fourth telescopic cylinder is provided with a second bearing seat, which is mounted on the frame through the fourth telescopic cylinder. The end of the second roller is rotatably mounted on the second bearing seat.

[0009] Preferably, a support plate is inclinedly provided on the side of the first roller shaft away from the fixed column. The height of the support plate is not higher than the height of the top of the first roller shaft. The height of the support plate gradually decreases along the direction away from the first roller shaft. The support plate is installed on the frame.

[0010] Preferably, the fixing seat and the cutting seat are respectively provided with sleeve holes, and the fixing seat or the cutting seat is movably fitted onto the fixing sleeve through the sleeve holes. The diameter of the sleeve holes and the inner cavity diameter of the two fixing rings are both matched with the outer wall diameter of the fixing sleeve. The side wall of the fixing ring is provided with threaded holes, and bolts are threaded into the threaded holes. The fixing ring is clamped and fixed onto the fixing sleeve by bolts. The fixing groove is opened along the top of the fixing seat to the middle of the fixing seat, and the diameter of the fixing rod matches the groove width of the fixing groove.

[0011] The advantages of this utility model are as follows: First, the utility model supports the fabric through a fixed plate, cuts the fabric conveyed on the fixed plate through a cutter, and restricts the fixed seat and the cutting seat to the fixed sleeve through two fixed rings, so that the fixed seat and the cutting seat can rotate around the fixed sleeve. Furthermore, this invention utilizes a fixed groove on the fixed base and a fixed rod fitted within the fixed groove to control the rotational position of the fixed base. Second telescopic cylinders at both ends of the fixed rod move the fixed rod, thereby adjusting the rotational position of the fixed base. The two ends of the first telescopic cylinder are hinged to the fixed base and the cutting base respectively, allowing the angle between them to be controlled by the telescopic movement of the first cylinder. Therefore, by controlling the telescopic movement of the second cylinder while keeping the telescopic movement of the first cylinder constant, multiple fixed bases and cutting bases fitted on the fixed base can rotate simultaneously, enabling the simultaneous cutting operation using multiple cutters. Alternatively, by controlling the telescopic movement of the first cylinder while keeping the telescopic movement of the second cylinder constant, the cutting base can rotate around the fixed base, allowing the cutting operation using a single cutter, thus providing multiple cutting methods.

[0012] Secondly, this invention utilizes a linkage assembly to control the spacing between several fixed sleeves, allowing for equal interval adjustment. By controlling the third telescopic cylinder, two linkage assemblies can be moved relative to each other to adjust the distance between the fixed sleeves, thus meeting the requirements for fabric cutting dimensions. Furthermore, this invention employs a fixing strip on the fixing post and slots on the fixed sleeves to constrain the rotation of the fixed sleeves, thereby preventing rotation and improving the stability of the fixed sleeves during use.

[0013] Furthermore, this invention utilizes a first bearing seat to rotatably mount one end of the first roller shaft onto the frame. A motor drives the first roller shaft to rotate. Fourth telescopic cylinders on both sides of the second roller shaft move the second roller shaft closer to or further away from the first roller shaft, adjusting the gap between them. A second bearing seat on the fourth telescopic cylinder allows the second roller shaft to be rotatably mounted on it. This compression and conveying of the fabric passing between the first and second roller shafts maintains tension, improving the stability of the fabric cutting process. Additionally, a support plate inclined on the side of the first roller shaft away from the fixed column supports and guides the conveyed fabric, guiding it into or out of the space between the first and second roller shafts.

[0014] In addition, the present invention uses a threaded inner hole on the fixing ring and a bolt fitted with a threaded inner hole to clamp and fix the fixing ring on the fixing sleeve, thereby facilitating the installation and removal of the fixing ring. Since the fixing seat and the cutting seat are constrained on the fixing sleeve by two fixing rings, the fixing seat and the cutting seat can also be installed and removed, so as to facilitate the maintenance of the present invention.

[0021] like Figures 1 to 6 As shown, a fabric cutting device for sofa production includes a frame 1, a horizontally mounted fixing plate 2 on the frame 1, and a cutter 3 mounted above the fixing plate 2. The cutter 3 cuts the fabric conveyed on the fixing plate 2. A fixing post 4 is horizontally mounted above the fixing plate 2. The fixing post 4 and the fixing plate 2 are respectively mounted on the frame 1. Several fixing sleeves 5 are mounted on the fixing post 4. A fixing seat 6, a cutting seat 7, and two fixing rings 8 are respectively fitted onto each fixing sleeve 5. The cutter 3 is mounted on the bottom end of the cutting seat 7, and the two fixing rings 8 are respectively mounted on the fixing sleeves. On both sides of the fixed sleeve 5, the fixing ring 8 and the fixing seat 6 are located between the two fixing rings 8. The inner sides of the two fixing rings 8 are in contact with the fixing seat 6 and the cutting seat 7 respectively, thereby using the fixing rings 8 to constrain the fixing seat 6 and the cutting seat 7 and prevent the fixing seat 6 or the cutting seat 7 from sliding off the fixed sleeve 5. A first telescopic cylinder 9 is provided between the fixing seat 6 and the cutting seat 7. The two ends of the first telescopic cylinder 9 are respectively hinged to the fixing seat 6 and the cutting seat 7, so that by controlling the telescopic movement of the first telescopic cylinder 9, the fixing seat 6 and the cutting seat 7 can be rotated relative to each other; the fixing A fixing rod 10 is installed above the column 4. A fixing groove 11 is provided on the fixing seat 6, and the fixing groove 11 is fitted onto the fixing rod 10. A second telescopic cylinder 12 is provided at each end of the fixing rod 10. The telescopic direction of the second telescopic cylinder 12 is perpendicular to the axial direction of the fixing column 4. The fixing rod 10 is mounted on the frame 1 through the second telescopic cylinder 12. By controlling the telescopic movement of the second telescopic cylinder 12, the fixing seat 6 is pushed to rotate around the fixing sleeve 5. Since the fixing seat 6 is connected to the cutting seat 7 through the first telescopic cylinder 9, the cutting seat can be driven by the first telescopic cylinder 9. 7 rotates together with the fixed base 6; therefore, if the second telescopic cylinder 12 is controlled to extend and retract while the extension and retraction of the first telescopic cylinder 9 remains constant, the fixed base 6 and the cutting base 7 on several fixed sleeves 5 can be rotated together, so that multiple cutters 3 can be used to perform cutting operations simultaneously; while if the first telescopic cylinder 9 is controlled to extend and retract while the extension and retraction of the second telescopic cylinder 12 remains constant, the cutting base 7 can be rotated around the fixed base 6, so that a single cutter 3 can be used to perform cutting operations, thus providing multiple cutting methods.

[0022] In this embodiment, one of the fixed sleeves 5 is installed in the middle of the fixed column 4, and the remaining fixed sleeves 5 are movably fitted onto the fixed column 4. An adjustment mechanism is provided on the side of the fixed sleeve 5 away from the first telescopic cylinder 9 to avoid interference between the first telescopic cylinder 9 and the adjustment mechanism. The adjustment mechanism includes several linkage groups 13 and a third telescopic cylinder 14 provided on the side of the linkage group 13 away from the fixed sleeve 5. The linkage group 13 includes two connecting rods of the same length, with the middle of the two connecting rods hinged to each other. The end of the connecting rod is hinged to the end of the connecting rod of the adjacent linkage group 13. The middle of one of the connecting rods is connected to the fixing ring 8 on one side of the fixed sleeve 5. The two ends of the third telescopic cylinder 14 are respectively connected to the two linkage groups 13. By controlling the extension and retraction of the third telescopic cylinder 14, the remaining fixed sleeves 5 are moved at equal intervals by means of the linkage group 13, so as to adjust the distance between adjacent fixed sleeves 5 by equal interval adjustment, thereby realizing the equal interval adjustment of the cutting distance to meet the needs of adjusting the fabric cutting size.

[0023] Specifically, a fixing strip 15 is provided between the connecting rod assembly 13 and the fixing column 4. The axial direction of the fixing strip 15 is parallel to the axial direction of the fixing column 4. The fixing strip 15 is installed on the side wall of the fixing column 4. A through groove 16 is provided on the fixing sleeve 5. The through groove 16 is opened on the inner wall of the fixing sleeve 5 and extends from one end of the fixing sleeve 5 to the other end of the fixing sleeve 5. The through groove 16 is movably fitted onto the fixing strip 15. The cross-sectional shape of the through groove 16 matches the cross-sectional shape of the fixing strip 15 to constrain the rotation of the fixing sleeve 5 and prevent the fixing sleeve 5 from rotating, thereby improving the stability of the fixing sleeve in use.

[0024] Please refer to it again. Figures 1 to 3The frame 1 is equipped with two first rollers 17, which are located on opposite sides of the fixed plate 2. One end of each first roller 17 is fitted with a first bearing seat 18, which is rotatably mounted on the bearing seat 18. The other end of each first roller 17 is fitted with a motor 19, which is connected to the drive end of the motor 19. Both the motor 19 and the bearing seat 18 are mounted on the frame 1. Above the first rollers 17 is a second roller 20. At both ends of the second roller 20, a fourth telescopic cylinder 21 is vertically mounted. A second bearing seat is mounted on the telescopic rod of each fourth telescopic cylinder 21. 22. The second bearing seat 22 is mounted on the frame 1 via the fourth telescopic cylinder 21. The end of the second roller shaft 20 is rotatably mounted on the second bearing seat 22. By controlling the telescopic movement of the fourth telescopic cylinder 21, the second roller shaft 20 is moved, thereby adjusting the size of the gap between the first roller shaft 17 and the second roller shaft 20 to squeeze the fabric between the first roller shaft 17 and the second roller shaft 20, so as to tension the cut fabric and improve the stability of the fabric cutting. By controlling the operation of the motor 19, the first roller shaft 17 is rotated, so as to push the fabric squeezed between the first roller shaft 17 and the second roller shaft 20 to move.

[0025] Specifically, a support plate 23 is inclinedly provided on the side of the first roller 17 away from the fixed column 4. The height of the support plate 23 is not higher than the height of the top of the first roller 17. The height of the support plate 23 gradually decreases along the direction away from the first roller 17. The support plate 23 is installed on the frame 1 to guide the conveyed fabric so as to guide the fabric to pass between the first roller 17 and the second roller 20 or to pass the fabric out of the first roller 17 and the second roller 20.

[0026] In this embodiment, the fixed seat 6 and the cutting seat 7 are respectively provided with sleeve holes 24. The fixed seat 6 or the cutting seat 7 is movably fitted onto the fixed sleeve 5 through the sleeve holes 24. The diameter of the sleeve holes 24 and the inner cavity diameter of the two fixing rings 8 are both matched with the outer wall diameter of the fixed sleeve 5, so that the fixed seat 6 and the cutting seat 7 can be constrained by the two fixing rings 8. The side wall of the fixing ring 8 is provided with a threaded hole 25. A bolt 26 is threaded into the threaded hole 25. The fixing ring 8 is clamped and fixed onto the fixed sleeve 5 by the bolt 26, so that the fixing ring 8 is assembled and fixed onto the fixed sleeve 5. The fixing groove 11 is opened along the top of the fixed seat 6 to the middle of the fixed seat 6. The diameter of the fixing rod 10 matches the groove width of the fixing groove 11, so that the fixing rod 10 is used to push the fixed seat 6 to rotate around the fixed sleeve 5.

[0027] The instructions for using this product are as follows: Figures 1 to 6As shown, firstly, according to the required fabric cutting size, the third telescopic cylinder 114 is controlled to extend and retract, causing the two connecting rod groups 13 to move relative to each other, thereby adjusting the distance between several fixed sleeves 5 to ensure that the fabric can be cut into standard sizes of equal length. Next, one end of the fabric is pulled through the first roller shaft 17 and the second roller shaft 20, and the fourth telescopic cylinder 21 is controlled to extend appropriately to tightly squeeze the fabric between the first roller shaft 17 and the second roller shaft 20, ensuring that the fabric remains stable during the cutting process. Then, if multiple cutters 3 need to be used for simultaneous cutting, the second telescopic cylinder 12 is controlled to extend, while ensuring that the extension and retraction of the first telescopic cylinder 9 remains constant, so that the fixed seats 6 and cutting seats 7 on the movable sets of several fixed sleeves 5 rotate in coordination, thereby enabling multiple cutters 3 to perform simultaneous cutting operations. Then, the motor 19 is started to move the fabric, thereby continuously performing the cutting operation. If only a single cutting blade 3 is needed for fabric cutting, the extension and retraction of the second telescopic cylinder 12 must remain constant. Simultaneously, the first telescopic cylinder 12 connected to the single cutting blade 3 is extended, causing the cutting blade 3 to rotate. Similarly, the motor 19 is started to move the fabric, ensuring the continuity and stability of the cutting operation. Furthermore, if partial cutting with the cutting blade 3 is required, the first telescopic cylinder 12 connected to the remaining cutting blades 3 is first retracted, causing the remaining cutting blades 3 to rotate in the opposite direction. The extension and retraction of the first telescopic cylinder 9 connected to the partial cutting blades 3 remains constant. Then, the second telescopic cylinder 12 is extended to allow partial cutting with the cutting blade 3. The motor 19 is started to move the fabric, ensuring continuous cutting operations to meet diverse cutting needs.

[0028] In this embodiment, the fabric is supported by the fixed plate 3, the fabric conveyed on the fixed plate 3 is cut by the cutter 3, and the fixed seat 6 and the cutting seat 7 are restricted to the fixed sleeve 5 by the two fixed rings 8, so that the fixed seat 6 and the cutting seat 7 can rotate around the fixed sleeve 5. Furthermore, this utility model uses a fixing groove 11 on the fixing base 6 and a fixing rod 10 fitted inside the fixing groove 11 to control the rotation position of the fixing base 6. Second telescopic cylinders 12 are provided at both ends of the fixing rod 10, so that the extension and retraction of the second telescopic cylinders 12 can move the fixing rod 10, thereby adjusting the rotation position of the fixing base 6. The two ends of the first telescopic cylinder 9 are respectively hinged to the fixing base 6 and the cutting seat 7, so that the angle between the fixing base 6 and the cutting seat 7 can be controlled by the extension and retraction of the first telescopic cylinder 9. Therefore, by controlling the extension and retraction of the second telescopic cylinder 12 while keeping the extension and retraction of the first telescopic cylinder 9 constant, the fixing bases 6 and cutting seats 7 fitted on multiple fixing sleeves 5 can rotate together, allowing multiple cutters 3 to be used simultaneously for cutting operations. Conversely, by controlling the extension and retraction of the first telescopic cylinder 9 while keeping the extension and retraction of the second telescopic cylinder 12 constant, the cutting seat 7 can rotate around the fixing base 6, allowing a single cutter 3 to be used for cutting operations, thus providing multiple cutting methods.

[0029] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
