Description

Technical Field

[0001] This utility model relates to the field of sofa production technology, and in particular to a multi-section cutting machine for sofa production. Background Technology

[0002] Sofas are one of the most common types of household furniture. In the production process of sofas, wood is usually used as a base, and then leather is applied to the base to complete the production and processing of the sofa. Since the wood inside the sofa has a multi-segment structure, the wood also needs to be cut into multiple segments according to the size during the processing.

[0003] Currently, when cutting sofa panels into multiple sections, workers typically mark the positions on the panels according to fixed dimensions and then manually cut them using a cutting machine. This method requires workers to slowly push the cutting machine to ensure accurate cutting dimensions, which greatly reduces the cutting efficiency of sofa panels in actual production. Furthermore, the frequent hand-held cutting operation by workers also poses certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-section cutting machine for sofa production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] Preferably, the two limiting blocks are slidably connected to the surfaces of the two positioning rods respectively, and the upper surface of the movable frame is provided with a threaded hole. An adjusting screw is threadedly connected to the inner wall of the threaded hole. The bottom end of the adjusting screw extends into the interior of the movable frame and is rotatably connected to the upper surface of the connecting block. A strip hole is provided on the upper surface of the gantry at a position corresponding to the adjusting screw.

[0009] Preferably, a circular hole is provided on the left side of the gantry frame, and a push rod is slidably connected to the inner wall of the circular hole. The right end of the push rod is fixedly connected to the right side of the movable frame.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example:

[0020] Reference Figure 1-3 A multi-section cutting machine for sofa production includes a worktable 1, a cutting groove on the upper surface of the worktable 1, a gantry frame 2 fixedly connected to the upper surface of the worktable 1, a cutting assembly slidably connected to the inner top wall of the gantry frame 2, the cutting assembly including a movable frame 3, a connecting block 4 slidably connected to the inner wall of the movable frame 3, a cutting frame 5 fixedly connected to the lower surface of the connecting block 4, a drive motor 6 fixedly connected to the front of the cutting frame 5, a rotating shaft 7 fixedly connected to the output end of the drive motor 6, and three cutting blades 8 fixedly connected to the surface of the rotating shaft 7. A number of clamping assemblies are slidably connected to the inner bottom wall of the cutting groove, and two friction assemblies are fixedly connected to the upper surface of the movable frame 3.

[0021] The lower surface of the movable frame 3 has a movable groove, and the front and rear inner walls of the movable groove have limit grooves. Positioning rods 9 are fixedly connected to the inner bottom walls of both limit grooves. Limiting blocks 10 are slidably connected to the inner walls of both limit grooves, and the opposite faces of the two limit blocks 10 are fixedly connected to the front and back of the connecting block 4, respectively. The two limit blocks 10 are slidably connected to the surfaces of the two positioning rods 9, respectively. The upper surface of the movable frame 3 has a threaded hole, and an adjusting screw 11 is threadedly connected to the inner wall of the threaded hole. The bottom end of the adjusting screw 11 extends into the interior of the movable frame 3 and is rotatably connected to the upper surface of the connecting block 4. The upper surface of the gantry 2 corresponds to the adjusting screw 11. A strip-shaped hole is provided at the position, and a round hole is provided on the left side of the gantry frame 2. A push rod 12 is slidably connected to the inner wall of the round hole. The right end of the push rod 12 is fixedly connected to the right side of the movable frame 3. Rotating the adjusting screw 11 can drive the connecting block 4 to descend. Since the connecting block 4 is blocked by the two positioning rods 9 and the limiting block 10, it descends vertically and has higher stability. After the connecting block 4 descends, it drives the cutting frame 5 to descend, so that the specific height of the cutting blade 8 can be manually adjusted. At the same time, the staff can push the push rod 12 to drive the movable frame 3 to move left and right, which makes it convenient for the three cutting blades 8 to complete multi-segment cutting operations on the board at the same time, greatly improving the cutting and forming efficiency of the board.

[0022] The clamping assembly includes a positioning frame 13. The upper surface of the positioning frame 13 has a screw hole, and the inner wall of the screw hole is threaded with a threaded rod 14. The inner wall of the positioning frame 13 is slidably connected with a pressure block 15. The bottom end of the threaded rod 14 extends into the interior of the positioning frame 13 and is rotatably connected to the upper surface of the pressure block 15. The left and right sides of the worktable 1 are threaded with screws 16 corresponding to the positions of the positioning frame 13. The end of the screw 16 near the cutting groove extends into the interior of the cutting groove and is rotatably connected to the side of the positioning frame 13. The two ends of the wood can be clamped by the two sets of positioning frames 13. The screws 16 can drive the two sets of positioning frames 13 to move towards the middle position, so as to be suitable for boards of different sizes. Rotating the threaded rod 14 can drive the pressure block 15 to descend, thereby pressing the board tightly in the positioning frame 13, ensuring the stability of the board during the cutting process. Even after the cutting is completed, the board will not shake, resulting in higher stability.

[0023] The friction assembly includes a connecting rod 17, with a strip frame 18 fixedly connected to the top of the connecting rod 17. The inner top wall of the gantry 2 has corresponding moving grooves at positions corresponding to the two strip frames 18. The two strip frames 18 are slidably connected to the inner walls of the two moving grooves, and the upper surface of the strip frame 18 has three rotating grooves. The inner wall of the rotating groove is rotatably connected to a friction wheel 20 via a circular shaft 19. When the operator uses the push rod 12 to move the movable frame 3 left and right, the movable frame 3 can move the strip frame 18 left and right within the moving groove via the connecting rod 17. Since the friction wheel 20 can rotate and contact the inner top wall of the moving groove, the strip frame 18 can both stabilize and limit the movable frame 3, and reduce the friction generated during the left and right movement of the movable frame 3, improving the smoothness of the left and right movement of the movable frame 3, thereby ensuring that the cutting blade 8 can smoothly complete multi-segment cutting operations on the wood.

[0024] Working principle: First, the wood to be cut is placed in the cutting groove. The left and right ends of the wood are held in place by the two sets of positioning frames 13. At the same time, rotating several screws 16 on the left and right sides of the worktable 1 moves the two sets of positioning frames 13 towards the center, thus positioning the left and right sides of the wood. Then, rotating the threaded rod 14 above the positioning frame 13 causes the pressure block 15 to descend on the inner wall of the positioning frame 13, pressing the upper surface of the wood to ensure the stability of the wood during processing. At this time, the drive motor 6 is turned on, which drives the cutting blade 8 to rotate. Simultaneously, the adjusting screw 11 is rotated. The adjusting screw 11 can drive the connecting block 4 to descend, thereby driving the cutting blade 8 to descend and contact the wood for cutting. At the same time, the operator can push the push rod 12 to move the movable frame 3 to the right, driving the cutting blade 8 to complete multi-segment synchronous cutting operations on the wood, which greatly improves the efficiency of wood cutting and shaping. Furthermore, the movable frame 3 can be limited by the connecting rod 17 and the strip frame 18 during movement, resulting in higher stability. The friction wheel 20 rotates and contacts the inner wall of the moving groove, which can significantly reduce the resistance of the movable frame 3 during movement, ensuring the smoothness of the movement of the movable frame 3 when the operator pushes the push rod 12.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
