Description

Technical Field

[0001] The invention belongs to the field of clothing cutting equipment, in particular to a cloth cutting device. Background Art

[0002] In the current garment-making process, fabrics need to be cut in batches in advance. The fabrics come in in the form of fabric rolls, which need to be unfolded and then sent to the cutting equipment for cutting. When the fabric is sent from the fabric roll to the cutting equipment, the fabric will be deformed or twisted, resulting in cutting misalignment and reduced cutting accuracy. As the fabric is cut continuously, the error gradually increases and the fabric may fold, which not only affects subsequent work but also affects the quality of the fabric.

[0003] At present, the cutting device in patent CN202310549302.3 fixes the cloth to avoid misalignment in cutting. After the cloth is placed, the cloth is positioned, pressed and flattened by a lifting component. However, the problem of misalignment and uneven cutting of the cloth when it is extended from the cloth roll is not solved. Cutting the cloth from the cloth roll into the required size can facilitate the subsequent cutting and sewing processes. Therefore, avoiding errors in the discharge of the cloth roll and deformation of the cloth is the main problem that needs to be solved at present. Summary of the invention

[0004] The present invention provides a cloth cutting device which can avoid deformation and folding of cloth during the cutting process of cloth rolls and improve cutting accuracy, and is particularly suitable for batch cutting of cloth rolls of specified sizes. The technical problem to be solved is that the cloth rolls are prone to precision errors during the cutting process, and the cloth is prone to folding and deformation.

[0005] The technical solution adopted by the present invention is:

[0015] The above structure has the following beneficial effects:

[0016] 1. Since the flattening device is used to flatten the cloth, the cloth is stretched and flattened by the upper flattening wheel and the lower flattening wheel, which overcomes the problem that the current cloth roll will deform and fold during the stretching and cutting process, so that the cloth remains flat during the stretching and cutting process, making the cutting smoother and more beautiful.

Since the cutting platform is used in conjunction with the cutting device and the stretching device for cutting, the stretching degree of the fabric can be adjusted by the tensioning wheel, which overcomes the problem of fabric bending under the action of gravity during the fabric stretching process, thereby ensuring that the fabric remains flat and tight during the cutting process, avoiding fabric bending caused by gravity.

[0018] 3. Due to the use of zigzag stretching device and cutting table, the cloth can be pulled quickly and conveniently, and the cloth is stabilized by the pressure wheel and the fixing bar, which overcomes the problem of cloth shaking during cutting, making the cloth cutting more neat and improving the cutting accuracy.

The fastening pin 1-7 can cooperate with the relative position of the fixed slideway 1-1 and the sliding block 1-4 through the thread and the strip hole, and the locking pin 1-6 can cooperate with the relative position of the fixed slide rail 1-3 and the rotating slider 1-5 through the thread and the strip hole. The upper flattening wheel 1-8 is located above the lower flattening wheel 1-3. The flattening device 1 and the cutting platform 2 are opposite at the ends. The sliding plates 2-1 are provided on both sides of the cutting platform 2. The cutting device 3 is provided at the end of the sliding plate 2-1. The cutting device 3 is located near one end of the flattening device 1. The cutting device 3 is connected to the cutting platform 2 through screws, and the stretching device 4 is slidably connected above the sliding plate 2-1. The flattening device 1 flattens the cloth through the upper flattening wheel 1-8 and the lower flattening wheel 1-3, thereby preventing the cloth from being deformed and folded. Two sliding blocks 1-4 are provided in the flattening device 1, and the two sliding blocks 1-4 are respectively slidably connected to the two slide rails 1-2, and the centers of the two rotating slide blocks 1-5 are respectively rotatably connected to the lower flattening wheel 1-3 or the upper flattening wheel 1-8, and the rotating slide blocks 1-5 are locked by the locking pins 1-6, and the sliding blocks 1-4 are locked by the fastening pins 1-7. The positions of the two flattening wheels can be quickly adjusted at the appropriate position, so that the fabric of the fabric roll can be stretched by the upper flattening wheel 1-8 and the lower flattening wheel 1-3.

[0035] The cutting platform 2 is configured as a conveyor belt, which can quickly output the cut fabric. A tensioning wheel 2-2 is provided at the end of the cutting platform 2 close to the flattening device 1. The two ends of the tensioning wheel 2-2 are respectively connected to two connecting rods, and the ends of the two connecting rods away from the tensioning wheel 2-2 are connected to the cutting platform 2. The connecting rod of the tensioning wheel 2-2 can be locked by a friction plate or a screw, so that the tensioning wheel 2-2 is fixed at any angle to prevent the fabric from being deformed due to gravity and ensure that the fabric remains tensioned.

[0036] The cutting device 3 includes a fixed frame 3-1, a pressing wheel 3-2, a fixed bar 3-3, a cutting knife 3-4, a cutting table 3-5 and a guide table 3-6. The two ends of the fixed frame 3-1 are slidably connected to the sliding plate 2-1. The fixing frame 3-1 is connected to the pressing wheel 3-2 below by a cylinder or a hydraulic cylinder. The pressing wheel 3-2 does not affect the dragging of the cloth while pressing the cloth, which can avoid deformation of the cloth during the cutting process and ensure the cutting accuracy. The two ends of the pressing wheel 3-2 are connected to the inner wall of the fixed frame 3-1 through a pressing groove 3-7 to reduce the radial force of the telescopic cylinder during the dragging process. The fixing frame 3-1 is connected to the fixing bar 3-3 below by a cylinder or a hydraulic cylinder. An elastic pad is arranged below the fixing bar 3-3. The fixing bar 3-3 is used to completely fix before cutting. The cloth can be positioned thereby, and the elastic pad can avoid damage to the equipment. The cutting knife 3-4 is connected to the fixing frame 3-1 through a motor or a cylinder. The blade surface of the cutting knife 3-4 is inclined. The inclined blade surface can use shear force to cut, thereby improving the cutting accuracy of the cloth. A cutting table 3-5 is arranged below the fixing frame 3-1, below the fixing bar 3-3 and the cutting knife 3-4. The cutting table 3-5 cooperates with the cutting knife 3-4 for cutting. The cutting table 3-5 is connected to the guide table 3-6 through screws below. The inner wall of the fixing frame 3-1 is welded at both ends of the guide table 3-6. A grid-like tooth shape is arranged at the end of the guide table 3-6 away from the flattening device 1, and the pressing wheel 3-2, the fixing bar 3-3 and the cutting knife 3-4 are arranged in sequence from the end close to the flattening device 1.

[0037] The stretching device 4 includes a lower clamping plate 4-1, an upper clamping plate 4-2 and a connecting platform 4-3. The connecting platform 4-3 is connected to the upper clamping plate 4-2 through a telescopic device. The lower clamping plate 4-1 is arranged below the upper clamping plate 4-2. The connecting platforms 4-3 are welded at both ends of the lower clamping plate 4-1. The upper clamping plate 4-2 and the lower clamping plate 4-1 are arranged on one side of the cutting device 3. The tooth shape of the upper clamping plate 4-2 is staggered with the tooth shape of the guide platform 3-6. The tooth shape of the lower clamping plate 4-1 is staggered with the tooth shape of the guide platform 3-6. The shapes are staggered, and the tooth shapes of the upper clamping plate 4-2 and the lower clamping plate 4-1 cooperate with each other to clamp the cloth. The cloth at the tooth shape of the guide platform 3-6 can be clamped and dragged through the staggered tooth shapes. The clamping and dragging can be performed quickly, which is convenient for cutting out the cloth of a specified length and improving work efficiency. The upper clamping plate 4-2 is higher than the upper plane of the guide platform 3-6, and the lower clamping plate 4-1 is lower than the upper plane of the guide platform 3-6. Through the staggered insertion of the tooth shapes, the cloth can be quickly and conveniently pulled from the platform.

[0038] A flattening groove 1-9 is arranged on the outer surface of the lower flattening wheel 1-3. The flattening groove 1-9 is a spiral groove. The rotation directions of the two ends of the spiral groove are opposite, and the feeding direction of the spiral groove points from the middle of the lower flattening wheel 1-3 to the two ends. The friction force can be used to flatten the cloth during the rotation of the lower flattening wheel 1-3 to prevent the cloth from bending and folding.

[0039] A flattening ring 1-10 is arranged on the outer surface of the upper flattening wheel 1-8. The flattening ring 1-10 is a spirally raised structure. The raised flattening ring 1-10 starts from the middle of the upper flattening wheel 1-8 and has opposite rotation directions at both ends. The feeding direction of the flattening ring 1-10 points from the middle of the upper flattening wheel 1-10 to both ends. The friction force is used to tension and stretch the previously flattened fabric here, simulating manual stretching of the fabric, avoiding the shape recovery and wrinkles of the fabric, so that the flattening effect is better and the fabric can remain flat.

[0040] Limiting blocks 2-3 are provided at both ends of the slide groove of the sliding plate 2-1 to prevent the stretching device 4 from falling or hitting the cutting device 3 during movement, thereby ensuring stable and safe operation.

[0041] How this example works:

[0042] During use, the end of the cloth roll is wound around the upper flattening wheel 1-8, and after winding half a circle, it is wrapped around the lower flattening wheel 1-3 half a circle. After that, the cloth is passed over the tensioning wheel 2-2 and placed on the guide platform 3-6. Then, the pressing wheel 3-2 is pushed by the cylinder to press the end of the cloth. Then, the stretching device 4 is moved so that the tooth profiles of the upper clamping plate 4-2 and the lower clamping plate 4-1 are matched and plugged with the tooth profiles of the guide platform 3-6. The upper clamping plate 4-2 and the lower clamping plate 4-1 are clamped with the end of the cloth by the cylinder. Then, the sliding stretching device 4 can pull the cloth out, and the pressing wheel 3-2 can ensure that the cloth will not be skewed or bent during the stretching process, so that the cloth has good flatness. The cloth is pressed and fixed by the fixing strip 3-3, and the cutting knife is started to cut the cloth, so that the cloth can complete the cutting work of a specified length of cloth. The stretching device 4 can be recycled to continuously cut the cloth of the specified size, which is convenient for improving the cutting accuracy and quality. With good positioning and fixing and in conjunction with the cloth flattening device, the cloth can ensure good flatness and cutting accuracy; if the cloth is bent due to gravity during the process from the flattening device 1 to the cutting platform 2, the tensioning wheel 2-2 can be used for adjustment, and the tensioning wheel 2-2 is used to support the cloth to avoid deformation of the cloth due to gravity, thereby ensuring the flatness of the cloth during transportation. Through the cooperation of flattening, cutting, and dragging multiple processes, the advantages of friction flattening, tensioning and shaping, positioning cutting, and uniform dragging are used to cooperate with each other to carry out the cutting work, so that the cloth can be cut neatly, the cloth is flat, and the cutting length is stable, which greatly improves the quality of the cutting work.

[0043] The flattening groove 1-9 and the flattening circle 1-10 use the friction force to flatten the cloth through the spiral structures with opposite rotation directions at both ends to prevent the cloth from bending. The bending and skewing of the cloth will cause the cloth to fold over time, thereby causing the cloth to be cut crookedly and unevenly, and the size will also be affected, and the incision will be uneven. The flattening groove 1-9 and the flattening circle 1-10 effectively overcome the problems existing in the existing cutting equipment, and the cloth can be flatter. The cutting device 3 makes the cutting accuracy more precise, avoids the problem of reduced cutting shape and accuracy caused by long-term cutting work, and improves work efficiency and effectiveness.
