Description

Technical Field

[0001] This utility model relates to the field of raw edge cutting technology, specifically a raw edge cutting machine for trousers. Background Technology

[0002] The main functions of fabric raw edge trimming include preventing fabric from fraying, enhancing the refinement of clothing, and improving the appearance and texture of the fabric. Raw edge treatment is an essential step in the fabric production process. It ensures that the edges of the fabric are flat and prevents the fabric from fraying or coming apart during use. Before the hem of trousers is finished, the raw edges need to be trimmed using a cutting machine.

[0003] A search revealed a utility model patent in China with publication number CN220202284U, which discloses a fabric cutting machine. This utility model uses a movable measuring component to adjust the position of the movable frame and adjust the position of the cutting blade according to the cutting size. During the adjustment process, the movable frame moves the bottom movable plate to slide against the surface of the measuring ruler. The measuring ruler can measure the distance of the movable frame's movement and adjustment. The position of the movable frame depends on the cutting length of the fabric, thus facilitating workers to cut fabric of a specific length.

[0004] This invention facilitates workers in cutting fabrics to specific lengths. However, waste fabric or lint generated during the cutting process remains on the surface of the workbench and needs to be manually cleaned regularly. Otherwise, the accumulation of waste fabric on the workbench will affect the normal use of the cutting device. Furthermore, in the prior art, workers need to manually fix the trousers during the fabric cutting or trouser hem cutting process. This is not only time-consuming and labor-intensive, but also prone to uneven hem cutting due to deviations in the fixing position or wrinkles in the trouser hem, which affects the subsequent trouser production quality.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-5As shown in this embodiment, a trouser edge cutting machine includes a mounting platform 1, on which a positioning plate 2 is fixedly mounted. The positioning plate 2 is perpendicular to the mounting platform 1. A mounting plate 3 is fixedly mounted on the rear side of the positioning plate 2. A third slide 19 is slidably mounted inside the mounting plate 3. A brush 21 is provided on the third slide 19. The brush 21 is in contact with the surface of the positioning plate 2. The brush 21 is rotatably connected to the third slide 19 through a mounting shaft 26. A gear 22 is sleeved on the mounting shaft 26. A rack 23 is slidably mounted inside the third slide 19. The rack 23 is meshed with the gear 22. The third slide 19 is equipped with a flying disc 25, which is rotatably connected to the third slide 19 via a pivot. A connecting rod 24 is provided between the flying disc 25 and the rack 23. The two ends of the connecting rod 24 are rotatably connected to the flying disc 25 and the rack 23 respectively via pivots. After the pants are fixed on the mounting platform 1 and the positioning plate 2, the movement of the moving frame 5 in the mounting frame 4 drives the fixed frame 7 and the cutting blade 8 to move, completing the cutting of the raw edges of the pants. The remaining waste fabric after cutting is left on the positioning plate 2 under the action of the second pressure rod 17. Releasing the second pressure rod 17 releases the fixation of the waste fabric, allowing the waste fabric to be removed. Under the influence of gravity, it automatically falls from the vertically positioned positioning plate 2. A third screw 20 is installed inside the mounting plate 3. Both ends of the third screw 20 pass through the mounting plate 3 and are rotatably connected to it via bearings. The third screw 20 passes through the third slide 19 and is threadedly connected to it. A motor in the third slide 19 drives the fly disk 25 to rotate, which, in conjunction with the connecting rod 24, causes the rack 23 to slide back and forth within the third slide 19. This, in conjunction with the gear 22, causes the mounting shaft 26 to drive the brush 21 to swing left and right on the third slide 19. The brush 21 is in contact with the surface of the positioning plate 2. During the swinging process, impurities attached to the positioning plate 2 are cleaned to maintain the cleanliness of the device and avoid affecting the subsequent cutting and processing of the pants. The mounting platform 1 and the positioning plate 2 are fixedly installed with a mounting frame 4. A movable frame 5 is slidably installed in the mounting frame 4. A lead screw 6 is provided in the mounting frame 4. The two ends of the lead screw 6 pass through the mounting frame 4 and are rotatably connected to the mounting frame 4 through bearings. The lead screw 6 passes through the movable frame 5 and is threadedly connected to the movable frame 5. A fixed frame 7 is slidably installed in the movable frame 5. A cutting blade 8 is rotatably installed on the fixed frame 7. The cutting blade 8 is aligned with the joint of the mounting platform 1 and the positioning plate 2.

[0024] like Figures 1-4As shown, a first slide 9 is slidably mounted on the mounting platform 1. Two sets of symmetrically distributed clamping rings 13 are rotatably mounted on the first slide 9. Two sets of symmetrically distributed torsion springs 14 are sleeved on the first slide 9. The two ends of the torsion springs 14 are fixedly connected to the corresponding clamping rings 13 and the first slide 9, respectively. Two sets of symmetrically distributed first cylinders 12 are fixedly mounted on the first slide 9. A first pressure rod 11 is provided on the first slide 9. The first pressure rod 11 is connected to the output end of the piston rod of the two sets of first cylinders 12, respectively. A first screw 10 is provided inside the mounting platform 1. The two ends of the first screw 10 are respectively inserted through... A first screw 10 passes through the mounting platform 1 and is rotatably connected to the mounting platform 1 via bearings. A second slide 15 is slidably mounted inside the positioning plate 2. Two sets of symmetrically distributed second cylinders 18 are fixedly mounted on the second slide 15. A second pressure rod 17 is provided on the second slide 15, with both ends of the second pressure rod 17 connected to the output ends of the piston rods of the two sets of second cylinders 18, respectively. A second screw 16 is provided inside the positioning plate 2, with both ends of the second screw 16 passing through the positioning plate 2 and rotatably connected to the positioning plate 2 via bearings. The second screw 10 passes through the first slide 9. The second slide 15 is threadedly connected to the second slide 15. Based on the actual length of the pants and the cutting position, the motor in the positioning plate 2 is activated to drive the second screw 16 to rotate, adjusting the positions of the second slide 15 and the second pressure rod 17. The pants are then passed through the second pressure rod 17 and the first pressure rod 11, with the waistband aligned with the two sets of clamps 13. The two sets of clamps 13 are then bent, and under the action of the torsion spring 14, they are aligned and fixed to the waistband. The first cylinder 12 and the second cylinder 18 are activated respectively, causing the first pressure rod 11 and the second pressure rod 17 to press the trousers onto the mounting platform 1. On the positioning plate 2, the motor in the starting mounting plate 3 drives the first screw 10 to rotate, and the first slide 9 drives the pants to slide on the mounting platform 1 and the positioning plate 2 until the cutting edge is aligned with the seam of the mounting platform 1 and the positioning plate 2. Then, the cutting is completed by the cutting blade 8. The fixing work before cutting the pants does not need to be done manually by the staff. Under the action of the clamping ring 13, the first pressure rod 11 and the second pressure rod 17, the pants are ensured to be flat and unfolded on the cutting machine. During the cutting process, the first pressure rod 11 and the second pressure rod 17 keep the pants from wrinkling due to the action of the cutting blade 8, which would affect the neatness of the cutting.

[0025] This utility model provides a trouser edge cutting machine. The specific working principle is as follows: After the trousers are fixed on the mounting platform 1 and positioning plate 2, the movement of the movable frame 5 in the mounting frame 4 drives the fixed frame 7 and the cutting blade 8 to move, completing the cutting of the trouser edges. The remaining waste fabric after cutting remains on the positioning plate 2 under the action of the second pressure rod 17. Releasing the second pressure rod 17 releases the fixation of the waste fabric, allowing it to automatically fall from the vertically positioned positioning plate 2 under gravity. Meanwhile, the motor in the third slide 19 drives the fly disc 25 to rotate, which, in conjunction with the connecting rod 24, causes the rack 23 to slide back and forth in the third slide 19. This, in conjunction with the gear 22, causes the mounting shaft 26 to drive the brush 21 to swing left and right on the third slide 19. The brush 21 is in contact with the surface of the positioning plate 2. During the swinging process, the brush 21 cleans the impurities attached to the positioning plate 2, maintaining the cleanliness of the device and avoiding affecting subsequent trouser cutting. Based on the actual length of the trousers and the cutting position, the motor in the positioning plate 2 is activated to drive the second screw... Rotating lever 16 adjusts the positions of the second slide 15 and the second pressure lever 17. The trousers are passed through the second pressure lever 17 and the first pressure lever 11, and the waistband is aligned with the two sets of clamps 13. By bending the two sets of clamps 13, the two sets of clamps 13 are aligned and fixed to the waistband under the action of the torsion spring 14. The first cylinder 12 and the second cylinder 18 are activated respectively, causing the first pressure lever 11 and the second pressure lever 17 to press the trousers onto the mounting platform 1 and the positioning plate 2 respectively. The motor in the mounting plate 3 is activated, driving the first screw 10. As the first carriage 9 rotates, it causes the pants to slide on the mounting platform 1 and the positioning plate 2 until the cutting edge is aligned with the seam of the mounting platform 1 and the positioning plate 2. Then, the cutting is completed by the cutting blade 8. The fixing work before cutting the pants does not need to be done manually by the staff. Under the action of the clamping ring 13, the first pressure bar 11 and the second pressure bar 17, the pants are ensured to be laid flat on the cutting machine. During the cutting process, the first pressure bar 11 and the second pressure bar 17 keep the pants from wrinkling due to the action of the cutting blade 8, which would affect the neatness of the cut.
