[0002] In sofa production, cutting is one of the most crucial processes, directly impacting material utilization, production efficiency, and finished product quality. Traditional sofa cutting methods involve manual cutting of materials such as leather, fabric, or foam along templates using electric shears or straight cutters. This method suffers from significant human error, resulting in uneven edges on the cut pieces, which affects subsequent sewing and assembly. Furthermore, material layout relies heavily on manual experience, making it difficult to optimize utilization and meet the demands of large-scale orders. Summary of the Invention

One end of the compression spring is fixed on the pressing component, and the other end is fixed to the bottom of the first connecting component.

[0012] Furthermore, the clamping mechanism includes a bracket, a clamping cylinder, and a clamping plate.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] like Figure 1-8As shown, a cutting device for sofa production includes a machine base 1 and movable components 2 slidably arranged on both sides. A drive mechanism 3 is fixedly installed at the upper end of the movable components 2. The drive mechanism 3 is located above the machine base 1 and has a cutter. A feeding roller 4 is provided at one end of the machine base 1, and a discharging roller 5 is detachably provided at the other end of the machine base 1. A pressing mechanism 6 is installed on the machine base 1 and is located between the feeding roller 4 and the drive mechanism 3. Figure 3 and Figure 4 As shown, the moving component 2 includes two parallel moving frames 21. The lower end of each moving frame 21 is slidably connected to the upper sides of the machine base 1. A first motor 22 is disposed on one side of one moving frame 21. The output end of the first motor 22 is provided with a first gear 23. A rack 24 is provided on the side wall of the machine base 1. The rack 24 meshes with the first gear 23. The two ends of the drive mechanism 3 are fixedly disposed on the upper end of each moving frame 21. The first motor 22 drives the first gear 23 to move along the rack 24, thereby driving the drive mechanism 3 to move back and forth along the machine base 1.

[0034] like Figure 5 As shown, the drive mechanism 3 includes a first drive mechanism 31, a second drive mechanism 32, and a fixed base 33. The two ends of the first drive mechanism 31 are fixedly mounted on the upper end of each movable frame 21. The second drive mechanism 32 is mounted on the first drive mechanism 31 and is perpendicular to it. The fixed base 33 is mounted on the second drive mechanism 32. The cutter is detachably mounted on the fixed base 33. The first drive mechanism 31 drives the second drive mechanism 32 to move left and right, and the second drive mechanism 32 drives the cutter to move up and down. The second drive mechanism 32 and the first drive mechanism 31 have the same structure. The first drive mechanism 31 includes a frame, a slide table, a lead screw, and a second motor. The two ends of the frame are fixedly mounted on the upper end of each movable frame 21. The slide table is mounted on the frame... The device features a sliding connection, with the lead screw located inside the frame and both ends rotatably connected to the frame. The middle of the lead screw is threadedly connected to the slide table. A second motor is fixedly mounted at one end of the frame, with its output connected to the lead screw. A second drive mechanism 32 is fixedly mounted on the slide table and slidably connected to the frame, increasing the stability of the device's operation. The first motor 22 drives the lead screw to rotate, which in turn moves the slide table left and right, thereby driving the second drive mechanism 32 to reciprocate left and right. The second drive mechanism 32 drives the cutter to reciprocate vertically up and down, enabling the cutter to move left and right and up and down. The moving component 2 allows the cutter to reciprocate back and forth, thus enabling the setting of the cutter's cutting path, material cutting, material layout design, and optimization of material utilization.

[0035] In implementation, the machine 1 includes a frame, a conveyor belt, a drive motor, a drive shaft, and a driven shaft. The drive shaft and driven shaft are arranged in parallel and are rotatably mounted on opposite sides of the frame. The drive motor is fixedly mounted on the frame, and its output end is connected to the drive shaft. The two ends of the conveyor belt are respectively mounted on the drive shaft and the driven shaft. Starting the drive motor drives the drive shaft to rotate, which in turn drives the driven shaft to rotate via the conveyor belt. The material to be cut is placed onto the conveyor belt through the feeding roller 4. The drive motor drives the drive shaft, which, in conjunction with the driven shaft, moves the material to be cut from one end to the other via the conveyor belt. Component 2 enables the drive mechanism 3 to move back and forth along the machine base 1. The first drive mechanism 31 enables the cutter to move left and right, and the second drive mechanism 32 enables the cutter to move up and down. Furthermore, by controlling the drive motor and the first drive mechanism 31 and the second drive mechanism 32, the cutting path of the cutter can be set, the material can be arranged, and the material utilization rate can be optimized. After cutting, the waste material is collected by the discharge roller 5. While collecting the waste material, the drive motor is started to drive the new material forward. The receiving box is placed below one side of the machine base 1 on the discharge roller 5. The receiving box is used to collect the cut material. The discharge roller 5 ensures the cleanliness of the processing site.

[0036] like Figure 5 and Figure 6 As shown, the fixing base 33 includes a first connecting member 331 and a second connecting member 332. The first connecting member 331 is fixedly installed on the sliding end of the second drive mechanism 32, and the second connecting member 332 is detachably connected to the first connecting member 331. The second connecting member 332 is used to lock and fix the cutter to the first connecting member 331. The first connecting member 331 has a guide strip 333 inside, and the cutter has a sliding groove. The guide strip 333 corresponds to the sliding groove, and the cooperation between the guide strip 333 and the sliding groove can position the relative position of the cutter. The fixed base 33 is provided with a pressing assembly 34, which includes a pressing part 341, a guide rod 342 and a compression spring 343. The pressing part 341 has a through hole in the middle, and the lower end of the cutter is located in the through hole. Multiple guide rods 342 are fixedly provided on the upper end surface of the pressing part 341. The upper end of each guide rod 342 is slidably connected to the lower end of the first connecting member 331. A compression spring 343 is sleeved around each guide rod 342. One end of the compression spring 343 is fixed on the pressing part 341 and the other end is fixed to the bottom of the first connecting member 331.

[0037] During implementation, the groove on the cutter is inserted into the guide strip 333 on the first connector 331, so that the lower end of the cutter is located in the through hole in the middle of the pressing member 341. Then, the second connector 332 is locked to the first connector 331 by the first bolt, thereby fixing the cutter. The pressing member 341 is moved to the surface of the material to be cut by the second drive mechanism 32 to press the material. The pressing member 341 is used to ensure the pressing of the material around the cutter during cutting, to avoid wrinkles during cutting, causing dimensional deviations, ensuring the flatness of the cutting edge, and improving the yield. By setting the compression spring 343, on the one hand, it can automatically compensate for the material thickness difference to ensure uniform pressing, and on the other hand, it can reduce the impact of equipment vibration on cutting accuracy and alleviate the instantaneous impact between the tool and the material.

[0038] like Figure 7 As shown, the clamping mechanism 6 includes a bracket 61, a clamping cylinder 62, and a clamping plate 63. A bracket 61 is provided on each of the opposite sides of the machine base 1 along the transmission direction. A clamping cylinder 62 is located on the top of each bracket 61. Both ends of the clamping plate 63 are located within the bracket 61, and each end of the clamping plate 63 is connected to the output end of a clamping cylinder 62. In practice, two sets of clamping mechanisms 6 are provided, and the clamping mechanisms 6 are respectively located on both sides of the cutter. The clamping mechanisms 6 are used to clamp the material to be cut at both ends of the machine base 1. After the material to be cut moves from the feeding roller 4 to the unloading roller 5, the clamping cylinder 62 is activated to push the clamping plate 63 to clamp the material to be cut. Then, the cutter is controlled by the moving component 2 and the drive mechanism 3 to cut the material, which avoids material deviation during cutting and improves processing accuracy. After all the material is cut, the clamping cylinder 61 is activated again to move the clamping plate 63 away from the material to be cut. The drive motor is activated to transmit the cut material forward, while new uncut material is transmitted at the same time. Meanwhile, the unloading roller 5 collects the waste material.

[0039] like Figure 3As shown, the feeding roller 4 includes several first rotating rollers 41 arranged parallel to each other, and the two ends of each first rotating roller 41 are rotatably connected to the machine base 1. Each end of each first rotating roller 41 is slidably provided with a positioning element 42, and each positioning element 42 is locked to the periphery of the first rotating roller 41 by screws. Both sides of the material can abut against one side of a positioning element 42, and the lower or upper surface of the material is rolled to the periphery of the first rotating roller 41. In practice, the first rotating rollers 41 are arranged in two rows, with an odd number in the upper row and an even number in the lower row, feeding the material from the upper... After being pulled out from the rack, the material passes through several first rotating rollers 41 in sequence, from bottom to top, and then is placed on the conveyor belt of the machine 1. The material is guided to unfold by a channel formed by several parallel first rotating rollers 41. On the one hand, the material travels along the set path, and with the help of the positioning component 42, it can avoid deviation or wrinkles. On the other hand, it maintains the appropriate tension of the material during the conveying process, avoiding wrinkles caused by being too loose and stretching deformation caused by being too tight, thus ensuring the cutting quality. Each roller is wrapped with silicone or polyurethane to increase friction and protect the material surface.

[0040] like Figure 8 As shown, the discharge roller 5 includes a second roller 51, bearings 52, and a second gear 53. A bearing 52 is installed at each end of the second roller 51, and each bearing 52 is mounted to the machine base 1 by a second bolt. One end of the second roller 51 passes through the bearing 52 and is fixedly connected to the second gear 53. The outer periphery of the second gear 53 meshes with a third gear 54, which is connected to the output end of a third motor 55, which is fixed to the machine base 1. In practice, a U-shaped mounting groove is provided at the front end of the machine base 1. The bearings 52 at both ends of the second roller 51 are placed into the mounting groove and fixed by the second bolts. The lower end of the second bolts abuts against the outer periphery of the bearing 52, fixing it in place. The third motor 55 drives the third gear 54 to rotate, which in turn drives the second gear 53 to rotate, thereby driving the second roller 51 to rotate, thus collecting waste materials and ensuring a clean production environment.

[0041] The working principle of a cutting device for sofa production is as follows: During operation, the material to be cut is sequentially placed onto the machine base 1 through multiple first rotating rollers 41. Multiple positioning components 42 are set to limit the positions of both ends of the material. The drive motor is started to move the material to the other end. The pressing mechanisms 6 at both ends of the machine base 1 are started to press the material. By controlling the moving component 2, the first drive mechanism 31 and the second drive mechanism 32, the cutter is driven to cut according to the set cutting path. After cutting, the pressing mechanism 6 is started to move the pressing plate 63 away from the material. The dropping roller 5 is started to collect the waste material. At the same time, the drive motor is started to output the uncut material again. At the same time, a receiving box is placed on the dropping side of the machine base 1. The drive motor outputs the uncut material again while the cut material falls into the receiving box. This cycle continues.

[0042] 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.
