Description

Technical Field

[0001] The invention relates to the technical field of clothing processing, in particular to a clothing surplus material trimming device. Background Art

[0002] As fashion trends change faster and faster, consumers' demand for diversified clothing styles is growing, which has prompted clothing companies to frequently update their product lines and produce smaller and more personalized batches. In the process, a large amount of clothing waste is inevitably generated.

[0003] In this regard, a clothing waste material trimming device disclosed in the patent publication number "CN108741361B" is provided with an adjusting bolt, an arc-shaped protective strip and a first connecting plate. The arc-shaped protective strip fits the outer side of the rotating shaft. Although it can prevent the cloth strips from falling and entangled with the rotating shaft during the cutting process to a certain extent, it affects the normal cutting work.

[0004] However, in actual use, when the motor drives the blade to cut the cloth, the blade will cause wrinkles in the process of displacement, which not only destroys the original flatness of the cloth, but also interferes with the accuracy of cutting edges. In addition, when cutting the cloth, it is usually necessary to press down one end of the cloth to keep the cloth stable and prevent it from moving at will during the cutting process. However, in this way, the blade is likely to cut the operator's hand directly. If a heavy object is used to press, due to the relatively smooth surface of the cloth, the heavy object lacks sufficient friction on the cloth. Under the influence of factors such as the vibration caused by cutting and the slight shaking of the machine, the cloth will easily slip out.

[0005] Based on this, the present application proposes a device for trimming the edge of garment surplus material. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a clothing waste material trimming device.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A clothing waste material trimming device, comprising a trimming table, a compacting component, a flattening component and a limiting component;

[0009] The edge cutting table is provided with a first slide groove, in which a first gear is rotatably connected, a cutting knife is fixedly connected to the first gear, a second slide rail is fixedly connected to the edge cutting table, a first rack is slidably connected to the second slide rail, two second slide grooves are provided on the edge cutting table, a lead screw is rotatably connected to the second slide groove, a slide rod is fixedly connected to the second slide groove, a gantry is slidably connected to the lead screw and the slide rod, and the edge cutting table is fixedly connected to a mounting box;

[0010] The compacting component is used to compact the remaining material after trimming;

[0011] The limiting component is used to fix the cloth in position;

[0012] The rolling assembly is used to roll the cloth flat.

[0013] Preferably, the trimming table is fixedly connected to a roller, one end of the roller is rotatably connected to a mounting box, the trimming table is rotatably connected to a third gear, the third gear is fixedly connected to a screw rod, the trimming table is fixedly connected to a first slide rail, a rack groove is slidably connected in the first slide rail, three first springs are fixedly connected in the rack groove, a mounting plate is fixedly connected below the first rack, and two fourth gears are rotatably connected to the mounting plate.

[0014] Preferably, the compaction assembly consists of two long plates, a plurality of second springs and two pressure plates, the two long plates are respectively fixedly connected to the two fourth gears, the two pressure plates are respectively arranged under the two long plates, and one end of a plurality of second springs is respectively fixedly connected to the two long plates, and the other end is respectively fixedly connected to the two pressure plates.

[0015] Preferably, the limiting assembly consists of a second rack, a second gear and a ratchet bar, the second rack is fixedly connected to the rack groove, the second gear is rotatably connected in the installation box, and the ratchet bar is fixedly connected to three first springs.

[0016] Preferably, the rolling assembly consists of two electric telescopic rods, a mounting frame and a rolling wheel, the two electric telescopic rods are respectively fixedly connected under the gantry, the mounting frame is fixedly connected to the output ends of the two electric telescopic rods, and the rolling wheel is rotatably connected to the mounting frame.

[0017] Preferably, an arc rail is fixedly connected to the trimming table, a storage box is provided under the mounting plate, the storage box is fixedly connected to the trimming table, two third racks are fixedly connected to the storage box, the two third racks are respectively meshed with two fourth gears, the two pressure plates are respectively slidably connected in the storage box, two third sliding grooves are provided on the inner wall of one side of the trimming table, and the two long plates are respectively rotatably connected in the two third sliding grooves.

[0018] Preferably, the cutting knife is rotatably connected to the first slide slot, the cutting knife is fixedly connected to the screw rod, a servo motor is fixedly installed in the installation box, the servo motor transmission shaft is fixedly connected to the third gear, and the third gear is meshingly connected to the second rack.

[0019] Preferably, the second gear is fixedly connected to the rotating roller, one end of the cutting knife is slidably connected to the arc track, and the two long plates are slidably connected in two third sliding grooves respectively.

[0020] The present invention has the following beneficial effects:

[0021] 1. Through the cutting blade, servo motor and other components, when the servo motor drives the third gear to rotate the screw rod, the screw rod drives the cutting blade to rotate, so that the cutting blade cuts the cloth. Compared with the horizontal sliding cutting of the traditional motor, the force exerted on the cloth during the whole cutting process of the cutting blade is more uniform and stable, which minimizes the unnecessary pulling and squeezing of the cloth, thereby effectively avoiding the formation of cloth wrinkles, ensuring that the cloth still maintains good flatness after cutting, and the cutting accuracy is also greatly guaranteed.

[0022] 2. Through the compaction component, when the cutting knife drives the first gear to rotate, the first rack will drive the mounting plate upward. During the upward process, the fourth gear on the mounting plate, under the action of the third rack, drives the long plate to rotate upward, so that the two pressing plates are opened, so that the cut cloth falls into the storage box. When the cutting knife is lifted again, the pressing plate will be pressed on the cut cloth again. Under the action of the second spring, the cloth in the storage box is compacted, thereby providing more effective collection space, so that the trimming device can handle more batches of cut cloth.

[0023] 3. Through the limit assembly, when the servo motor drives the cutting knife to rotate through the third gear and the lead screw, the third gear drives the second rack to make the rack groove slide downward. Since the inclined surface of the serrations on the ratchet bar is downward, the second gear will not rotate when the ratchet bar descends. Under the action of the straight surface of the serrations on the ratchet bar, the second gear cannot rotate toward the cutting knife. When the cutting knife trims the cloth, the cloth fixed on the roller will not be displaced due to the pulling force generated when the cutting knife cuts into the cloth, which will cause the cutting position to deviate and affect the cutting accuracy.

[0024] 4. After one end of the cloth is pulled from the roller to the first slide slot through the flattening assembly, the electric telescopic rod is started to drive the mounting frame down, so that the rolling wheel is pressed onto the cloth. The servo motor drives the third gear and the screw rod to rotate, so that the cutting knife is lifted after the previous round of work is completed. At the same time, the screw rod also drives the gantry to slide, so that the gantry drives the rolling wheel to flatten and exhaust the cloth to be cut, so that the wrinkles and curls on it are smoothed one by one, avoiding uneven lengths of the cut edges.

DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] Embodiment 1:

[0038] Reference Figure 1 , Figure 2 , Figure 4 , Figure 7and Figure 8 , a clothing waste material trimming device, comprising a trimming table 1, a compacting component, a flattening component and a limiting component;

[0039] A first slide 16 is provided on the trimming table 1, where the cloth will be trimmed. The first slide 16 is rotatably connected to the first gear 17, and the first gear 17 is fixedly connected to the cutting knife 2. The cutting knife 2 is rotatably connected to the first slide 16. When the cutting knife 2 rotates, the cloth can be trimmed. A second slide rail 25 is fixedly connected to the trimming table 1, and a first rack 18 is slidably connected to the second slide rail 25. The first rack 18 can slide up and down in the second slide rail 25. A mounting plate 28 is fixedly connected below the first rack 18, and two fourth gears 26 are rotatably connected to the mounting plate 28. When the first rack 18 slides, it can drive the mounting plate 28 and the two fourth gears 26 to slide up and down. The trimming table 1 is fixedly connected to a roller 6, and the roller 6 is used to carry the cloth before the cloth enters the trimming process, so that the cloth can start the trimming process in a more regular state. An arc track 3 is fixedly connected to the trimming table 1, and one end of the cutting knife 2 is slidably connected to the arc track 3. The arc track 3 defines a precise path for the movement of the cutting knife 2 to ensure the accuracy and standardization of the trimming. A storage box 8 is provided under the mounting plate 28, and the storage box 8 is fixedly connected to the trimming table 1 for collecting the remaining materials after cutting. Two third racks 27 are fixedly connected to the storage box 8, respectively, and the two third racks 27 are respectively meshed with the two fourth gears 26. When the two fourth gears 26 slide upward, they can rotate under the action of the third racks 27. The two pressing plates 31 are respectively slidably connected to the storage box 8 to ensure that the cut cloth can be pressed downward in the storage box 8. Two third slide grooves 30 are provided on the inner wall of one side of the trimming table 1, and the two long boards 9 are respectively rotatably connected in the two third slide grooves 30 to ensure that the long boards 9 can rotate when the fourth gear 26 rotates.

[0040] The compacting assembly is used to compact the remaining material after trimming. The compacting assembly consists of two long plates 9, a plurality of second springs 32 and two pressing plates 31. The two long plates 9 are respectively fixedly connected to the two fourth gears 26, so that the long plates 9 can rotate or slide up and down following the fourth gear 26. The two long plates 9 are respectively slidably connected in the two third slide grooves 30, so that the long plates 9 can slide up and down smoothly. The two pressing plates 31 are respectively arranged under the two long plates 9. One end of a plurality of second springs 32 is respectively fixedly connected to the two long plates 9, and the other end is respectively fixedly connected to the two pressing plates 31. In this way, when the thickness of the cloth in the storage box 8 changes, the pressing plate 31 can automatically adjust the force acting on the pressing plate 31 under the action of the second spring 32, ensuring that the pressing plate 31 can always compact the remaining material with appropriate pressure.

[0041] In this embodiment, when the cutting blade 2 rotates, the cutting blade 2 can cut the cloth. Compared with the traditional motor sliding horizontally for cutting, the force applied to the cloth during the entire cutting process of the cutting blade 2 is more uniform and stable, which minimizes unnecessary pulling and squeezing of the cloth, thereby effectively avoiding the generation of cloth wrinkles and ensuring that the cloth still maintains good flatness after trimming. The trimming accuracy is also greatly guaranteed. When the cutting blade 2 drives the first gear 17 to rotate, the first rack 18 will drive the mounting plate 28 upward. During the upward process, the fourth gear 26 on the mounting plate 28 drives the long plate 9 to rotate upward under the action of the third rack 27, so that the two pressing plates 31 are opened, so that the cut cloth falls into the storage box 8. When the cutting blade 2 is lifted again, the pressing plate 31 will be pressed on the cut cloth again. Under the action of the second spring 32, the cloth in the storage box 8 is compacted, thereby providing more effective collection space, so that the trimming device can process more batches of cut cloth.

[0042] Embodiment 2:

[0043] Different from the first embodiment, Figure 1 - Figure 3 , Figure 5 and Figure 6 , this embodiment also has the following further contents:

[0044] A first slide rail 21 is fixedly connected to the trimming table 1, and a rack groove 20 is slidably connected in the first slide rail 21. The rack groove 20 can slide up and down in the first slide rail 21, and three first springs 29 are fixedly connected in the rack groove 20. A mounting box 7 is fixedly connected to the trimming table 1, and one end of the roller 6 is rotatably connected to the mounting box 7. A third gear 23 is rotatably connected to the trimming table 1, and a servo motor 15 is fixedly installed in the mounting box 7. The drive shaft of the servo motor 15 is fixedly connected to the third gear 23, and the third gear 23 is meshingly connected to the second rack 24. Starting the servo motor 15 can drive the third gear 23 to rotate, thereby enabling the second rack 24 to slide.

[0045] The limiting assembly is used to fix and limit the cloth. The limiting assembly consists of a second rack 24, a second gear 19 and a ratchet bar 22. The second rack 24 is fixedly connected to the rack groove 20. When the second rack 24 slides, it can drive the rack groove 20 to slide. The second gear 19 is rotatably connected in the installation box 7. The second gear 19 is fixedly connected to the roller 6. The ratchet bar 22 is fixedly connected to three first springs 29. In this way, when the ratchet bar 22 slides downward, its inclined surface contacts the second gear 19, which will not cause the second gear 19 to rotate. Instead, under the action of the second gear 19, the first spring 29 is compressed to slide into the rack groove 20, and the ratchet bar 22 will limit the second gear 19, so that the second gear 19 limits the roller 6, so that the roller 6 will not rotate toward the direction of the first slide groove 16.

[0046] In this embodiment, when the servo motor 15 drives the cutting blade 2 to rotate through the third gear 23 and the screw rod 14, the third gear 23 drives the second rack 24 to make the rack groove 20 slide downward. During the downward sliding of the rack groove 20, the ratchet bar 22 descends together with the rack groove 20. Due to the downward inclined surface of the sawtooth of the ratchet bar 22, the ratchet bar 22 will not exert a force on the second gear 19 to make it rotate during the descending process. The second gear 19 is fixedly connected to the roller 6, and the sawtooth straight surface of the ratchet bar 22 also acts on the second gear 19 at this time, so that the second gear 19 cannot rotate toward the cutting blade 2, and the roller 6 cannot rotate toward the cutting blade 2. When the cutting blade 2 trims the cloth, the cutting blade 2 will generate a pulling force when it cuts into the cloth. Since the roller 6 is locked by the ratchet bar 22 and cannot rotate toward the cutting blade 2, the cloth fixed on the roller 6 will not be displaced due to the pulling force generated when the cutting blade 2 cuts into the cloth, thereby causing deviation in the trimming position and affecting the trimming accuracy.

[0047] Embodiment three:

[0048] Reference Figure 1 - Figure 3 and Fig. 9 , compared with the first embodiment and the second embodiment, in this embodiment:

[0049] Two second slide grooves 4 are provided on the trimming table 1, and a screw rod 14 is rotatably connected in the second slide groove 4, and a slide rod 13 is fixedly connected in the second slide groove 4. A gantry 5 is slidably connected to the screw rod 14 and the slide rod 13. When the screw rod 14 rotates, the gantry 5 can be driven to slide on the screw rod 14 and the slide rod 13. The cutting knife 2 is fixedly connected to the screw rod 14. When the screw rod 14 rotates, the cutting knife 2 can be rotated. The third gear 23 is fixedly connected to the screw rod 14. When the third gear 23 rotates, the screw rod 14 can be rotated.

[0050] The rolling assembly will be used to flatten the fabric, and the rolling assembly consists of two electric telescopic rods 12, a mounting frame 11 and a rolling wheel 10. The two electric telescopic rods 12 are respectively fixedly connected under the gantry 5, the mounting frame 11 is fixedly connected to the output ends of the two electric telescopic rods 12, and the rolling wheel 10 is rotatably connected to the mounting frame 11. The mounting frame 11 is driven by the electric telescopic rod 12 to enable the rolling wheel 10 to be pressed onto the fabric.

[0051] In this embodiment, first, one end of the cloth is pulled from the roller 6 to the first slide groove 16, and then the electric telescopic rod 12 is started to drive the mounting frame 11 to descend, so that the rolling wheel 10 is pressed onto the cloth, and the servo motor 15 drives the third gear 23 and the screw rod 14 to rotate, so that the cutting knife 2 is lifted after the previous round of work is completed. At the same time, the screw rod 14 also drives the gantry 5 to slide, so that the gantry 5 drives the rolling wheel 10 to flatten and exhaust the cloth to be cut, so that the wrinkles and curls on the cloth are smoothed one by one, and the uneven length of the cut edges is avoided.

[0052] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
