Description

Technical Field

[0001] This application relates to the field of garment manufacturing technology, specifically to a fabric cutting machine with high cutting quality and efficiency. Background Technology

[0002] A fabric cutting machine is a mechanical device specifically designed for cutting various types of fabrics. It is widely used in industries such as garment manufacturing, home textiles, bags, and automotive interiors. Through mechanical, electric, or CNC methods, it achieves precise cutting of fabrics, improving production efficiency and cutting quality.

[0003] However, most existing cutting machines only fix the edges of the fabric, such as by using clamps or pressure plates. During the cutting process, the high-speed movement of the cutting blade may cause vibrations in the fabric. When the cutting blade cuts in the middle of the fabric, the edge fixing method is difficult to suppress the vibration in the middle area of ​​the fabric, resulting in wavy cut edges, reduced cutting accuracy, and excessive stretching of the fabric fibers, leading to uneven fiber breakage, fraying, and jamming. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a fabric cutting machine with high cutting quality and efficiency, which has advantages such as improved cutting accuracy. It solves the problem that most existing cutting machines only fix the edges of the fabric, such as using clamps or pressure plates. During the cutting process, the high-speed movement of the cutting blade may cause vibration of the fabric. When the cutting blade cuts in the middle of the fabric, the edge fixing method is difficult to suppress the vibration in the middle area of ​​the fabric, resulting in wavy cutting edges, reduced cutting accuracy, and excessive stretching of fabric fibers, leading to uneven fiber breakage, fraying, and jamming.

[0005] To achieve the above objectives, this application provides the following technical solution: a fabric cutting machine with high cutting quality and efficiency, comprising a support base, a cutting table fixedly connected to the upper end of the support base, a suction box fixedly connected inside the cutting table, a plurality of suction holes arranged in a linear array at the upper end of the suction box, drive rollers rotatably connected to both sides inside the cutting table, a conveyor belt rotatably sleeved on the outer wall of the two drive rollers, a suction box fixedly connected to the bottom end of the cutting table, a suction pipe fixedly connected to the bottom end of the suction box, a fan fixedly connected inside the suction pipe, connecting square tubes fixedly connected to both sides of the suction box, and one end of each of the two connecting square tubes passing through the support base and the cutting table and fixedly connected to the suction box, an operating table provided on one side of the cutting table, and a material feeding rack provided at the end of the operating table away from the support base.

[0006] Through the above solution, the suction box generates negative pressure through the exhaust fan, adsorbing the fabric onto the cutting table through the exhaust holes. This creates uniform suction on the fabric, avoiding the problems of excessive local pressure damaging the fabric or insufficient pressure causing fabric displacement, which are common with traditional clamps or pressure plates. Negative suction fixation ensures the fabric is flat and firmly attached to the cutting table. During cutting, the friction between the cutting blade and the fabric generates vibration, which affects cutting accuracy and quality. Negative suction fixation comprehensively fixes the fabric, suppressing cutting vibration and maintaining a relatively stable state during cutting, reducing fiber pulling and jamming caused by vibration. The connecting square tubes on both sides of the suction box pass through the support base and the cutting table, providing a fixed connection. When the exhaust fan is working, airflow is evenly distributed within the suction box through the connecting square tubes, ensuring sufficient suction at each exhaust hole. The drive roller rotates the conveyor belt, achieving smooth fabric transport. The operating table is located on one side of the cutting table, allowing operators to easily remove the cut fabric and collect waste materials through the discharge rack, maintaining a clean production environment.

[0007] Furthermore, a first linear module is fixedly connected to both sides of the upper end of the cutting platform, and a moving beam is fixedly connected to the moving ends of the two first linear modules. A second linear module is fixedly connected to one side of the moving beam, and a cutting head is fixedly connected to the output end of the second linear module. A punching knife, a burr needle, and a cutting knife are fixedly connected to the end of the cutting head away from the moving beam.

[0008] With the above solution, the first linear module fixed on both sides of the upper end of the cutting table is connected to the moving beam at its moving end, and a second linear module is fixed on one side of the moving beam. Through the coordinated movement of these two linear modules, the cutting head can move in the horizontal and vertical directions, so that the cutting head can cut according to a pre-set complex path. Whether it is a straight line, a curve or various irregular shapes, it can complete the cutting. The cutting head integrates a punching knife, a cutting eye needle and a cutting knife, and can complete the processing steps of punching, cutting eye and cutting in one cutting process. This reduces the number of times the fabric is handled and adjusted, and improves production efficiency.

[0009] Furthermore, a plurality of electric push rods arranged in a linear array are fixedly connected inside the movable beam, and pressure plates are fixedly connected to the telescopic ends of the plurality of electric push rods.

[0010] The above method fixes one end of the fabric to the pressure plate during the fabric movement, and moves with the fabric to prevent the fabric from shifting due to external interference or other factors, thus preventing inaccurate cutting positions and affecting the overall pattern and quality of the garment.

[0011] Furthermore, multiple air outlet slots arranged in a linear array are provided on both sides of the support base.

[0012] The above solution allows the air outlet groove to guide the air drawn out by the exhaust fan out, preventing air from accumulating in the support base and weakening the negative pressure effect.

[0013] Furthermore, the feeding rack includes a support frame, with a movable wheel fixedly connected to the bottom end of the support frame, a receiving roller rotatably connected to one side inside the support frame, two baffles arranged in a mirror image fixedly connected to the outer wall of the receiving roller, and a crank handle fixedly connected to one end of the receiving roller that passes through the support frame.

[0014] With the above solution, the movable wheels fixedly connected to the bottom of the support frame allow the feeding frame to move easily between different working areas. As the main structure of the feeding frame, the support frame supports the weight of the take-up roller and the fabric, ensuring the stability of the waste fabric roll-up. The two mirror-distributed baffles fixedly connected to the outer wall of the take-up roller can limit the position of the fabric roll on the take-up roller, preventing the fabric from shifting during the take-up and unwinding process. The crank fixedly connected to one end of the take-up roller through the support frame provides the operator with a simple and easy-to-use manual control method. The operator can manually roll up the fabric by turning the crank.

[0015] Furthermore, the conveyor belt is at the same horizontal level as the upper end of the operating platform.

[0016] With the above solution, when the fabric moves from the conveyor belt to the operating table, the fabric can smoothly transition between the two, reducing fabric deformation caused by height difference and preventing jamming.

[0017] Furthermore, the conveyor belt is rotatably mounted inside the cutting table, and the suction box is fixedly mounted inside the conveyor belt.

[0018] The above solution integrates a rotating conveyor belt inside the cutting table and a fixed suction box inside the conveyor belt, forming an integrated device. The fixed suction box allows it to be closer to the fabric cutting position, enabling the fabric to be evenly fixed by negative pressure during the cutting process.

[0019] Furthermore, the conveyor belt is made of felt material.

[0020] Through the above method, the surface of the felt material has a rough texture, which can increase the friction between it and the fabric. During the fabric conveying process, this friction can prevent the fabric from sliding on the conveyor belt, ensuring that the fabric can be accurately conveyed to the cutting position. Furthermore, because the felt material is breathable, air can pass through, causing negative pressure to act on the fabric.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This high-quality, high-efficiency fabric cutting machine uses a suction box to generate negative pressure through a fan, which draws the fabric onto the cutting table through the suction port. This creates uniform suction, avoiding the problems of traditional clamps or pressure plates that can damage the fabric due to excessive localized pressure or cause displacement due to insufficient pressure. The negative suction method ensures the fabric is flat and firmly attached to the cutting table. During cutting, the friction between the cutting blade and the fabric generates vibration, which affects cutting accuracy and quality. The negative suction method comprehensively secures the fabric, suppressing cutting vibration and ensuring a smooth cut. The material remains relatively stable during the cutting process, reducing the occurrence of wire pulling and jamming caused by vibration. The connecting square tubes on both sides of the exhaust box pass through the support base and the cutting table and are fixedly connected to the exhaust box. When the exhaust fan is working, the airflow can be evenly distributed in the exhaust box through the connecting square tubes, ensuring that each exhaust hole can generate sufficient suction. The drive roller drives the conveyor belt to rotate, realizing the smooth transport of the fabric. The operating table is set on one side of the cutting table, making it convenient for operators to remove the cut fabric and collect the waste material after cutting through the material rack, which can keep the production environment clean.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment describes a high-quality and efficient fabric cutting machine, including a support base 1. A cutting table 2 is fixedly connected to the upper end of the support base 1. A suction box 3 is fixedly connected inside the cutting table 2. The suction box 3 has a hollow structure and multiple air extraction holes 4 arranged in a linear array at its upper end. The air extraction holes 4 move to draw in air and create negative pressure to adsorb the fabric. Drive rollers 5 are rotatably connected to both sides inside the cutting table 2. A conveyor belt 6 is rotatably sleeved on the outer wall of the two drive rollers 5. The drive rollers 5 drive the conveyor belt 6 to rotate, achieving stable fabric conveying. A suction box 7 is fixedly connected to the bottom end of the cutting table 2. An exhaust pipe 8 is fixedly connected to the bottom end of the suction box 7. An exhaust fan 9 is fixedly connected inside the exhaust pipe 8. The suction box 3 generates negative pressure through the exhaust fan 9, which adsorbs the fabric through the air extraction holes 4. On the cutting table 2, a uniform suction force is generated on the fabric. Both sides of the exhaust box 7 are fixedly connected with connecting square tubes 10. Both connecting square tubes 10 pass through the support base 1 and one end of the cutting table 2 and are fixedly connected to the exhaust box 7. The connecting square tubes 10 on both sides of the exhaust box 7 pass through the support base 1 and the cutting table 2 and are fixedly connected to the exhaust box 3. When the exhaust fan 9 is working, the airflow can be evenly distributed in the exhaust box 3 through the connecting square tubes 10 to ensure that each exhaust hole 4 can generate sufficient suction force. An operating table 11 is provided on one side of the cutting table 2. The operating table 11 is located on one side of the cutting table 2 to facilitate the operator to remove the cut fabric. A material rack 12 is provided at the end of the operating table 11 away from the support base 1. The waste material after cutting is collected through the material rack 12, which can keep the production environment clean.

[0032] Please see Figure 1 , Figure 2 and Figure 4The cutting table 2 has two fixedly connected first linear modules 13 on both sides of its upper end. The moving ends of the two first linear modules 13 are fixedly connected to a moving beam 14. A second linear module 15 is fixedly connected to one side of the moving beam 14. A cutting head 16 is fixedly connected to the output end of the second linear module 15. A punching knife 17, a cutting needle 18, and a cutting knife 19 are fixedly connected to the end of the cutting head 16 away from the moving beam 14. The moving ends of the first linear modules 13 fixed on both sides of the upper end of the cutting table 2 are connected to the moving beam 14, and the second linear module 15 is fixed to one side of the moving beam 14. Through the coordinated movement of these two linear modules, the cutting head 16 can move in both the horizontal and vertical directions, allowing it to cut along a pre-set complex path. It can cut straight lines, curves, and various irregular shapes. The cutting head 16 integrates a punching knife 17, a slit needle 18, and a cutting knife 19, enabling it to complete punching, slitting, and cutting processes simultaneously in a single cutting operation. This reduces the number of times the fabric needs to be handled and adjusted, improving production efficiency. The moving beam 14 has multiple electric push rods 20 arranged in a linear array fixedly connected inside. The telescopic ends of the multiple electric push rods 20 are fixedly connected to pressure plates 21. During the fabric movement, the pressure plates 21 fix one end of the fabric and move with the fabric, preventing the fabric from shifting due to external interference or other factors. This prevents inaccurate subsequent cutting positions, which could affect the overall pattern and quality of the garment. The support base 1 has multiple air vents 22 arranged in a linear array on both sides. The air vents 22 can guide the air drawn out by the exhaust fan 9 to be discharged, preventing air from accumulating in the support base 1 and weakening the negative pressure effect.

[0033] Please see Figure 1 , Figure 2 and Figure 5The feeding rack 12 includes a support frame 1201. A caster wheel 1202 is fixedly connected to the bottom of the support frame 1201. A take-up roller 1203 is rotatably connected to one side of the inside of the support frame 1201. Two mirror-distributed baffles 1204 are fixedly connected to the outer wall of the take-up roller 1203. A crank handle 1205 is fixedly connected to one end of the take-up roller 1203 that passes through the support frame 1201. The caster wheel 1202 fixedly connected to the bottom of the support frame 1201 allows the feeding rack 12 to move easily between different working areas. 01, as the main structure of the feeding frame 12, supports the weight of the take-up roller 1203 and the fabric, ensuring the stability of the waste fabric roll-up. Two mirror-distributed baffles 1204 fixedly connected to the outer wall of the take-up roller 1203 limit the position of the fabric roll on the take-up roller 1203, preventing the fabric from shifting during the take-up and feeding process. A crank 1205 fixedly connected to one end of the take-up roller 1203 through the support frame 1201 provides a simple and easy-to-use manual control method for the operator. The operator can rotate the crank 1205 to control the fabric roll. The crank handle 1205 is used to manually wind up the fabric. The upper end of the conveyor belt 6 and the operating table 11 are at the same horizontal line. When the fabric moves from the conveyor belt 6 to the operating table 11, the fabric can smoothly transition between the two, reducing fabric deformation caused by height difference and preventing jamming. The conveyor belt 6 is rotatably set inside the cutting table 2, and the suction box 3 is fixedly set inside the conveyor belt 6. The conveyor belt 6 is rotatably set inside the cutting table 2, and the suction box 3 is fixedly set inside the conveyor belt 6, forming an integrated device. The suction box 3 is fixed inside the conveyor belt 6, so that it can be closer to the fabric cutting position. During the cutting process, the fabric can be evenly fixed by negative pressure. The conveyor belt 6 is made of felt material. The surface of the felt material has a rough texture, which can increase the friction between it and the fabric. During the fabric conveying process, this friction can prevent the fabric from sliding on the conveyor belt 6, ensuring that the fabric can be accurately conveyed to the cutting position. And because the felt material is breathable, air can pass through, so that negative pressure is applied to the fabric.

[0034] In this embodiment, the high-quality and efficient fabric cutting machine uses a suction box 3 to generate negative pressure through a blower 9. This negative pressure, via the suction port 4, draws the fabric onto the cutting table 2, creating a uniform suction force. This avoids the problems associated with traditional clamps or pressure plates 21, where excessive local pressure damages the fabric or insufficient pressure causes displacement. The negative suction fixation ensures the fabric is flat and firmly attached to the cutting table 2. During cutting, the friction between the cutting blade 19 and the fabric generates vibration, which affects cutting accuracy and quality. The negative suction fixation method comprehensively secures the fabric, suppressing cutting vibration and ensuring a smooth cut. Maintaining a relatively stable state during the cutting process reduces the occurrence of wire pulling and jamming caused by vibration. The connecting square tubes 10 on both sides of the exhaust box 7 pass through the support base 1 and the cutting table 2 and are fixedly connected to the exhaust box 3. When the exhaust fan 9 is working, the airflow can be evenly distributed in the exhaust box 3 through the connecting square tubes 10, ensuring that each exhaust hole 4 can generate sufficient suction. The drive roller 5 drives the conveyor belt 6 to rotate, realizing the smooth conveying of the fabric. The operating table 11 is set on one side of the cutting table 2, which makes it convenient for operators to remove the cut fabric and collect the waste material after cutting through the material rack 12, thus maintaining a clean production environment.

[0035] The working principle of the above embodiments is as follows:

[0036] During operation, the fabric is smoothly conveyed to the cutting table 2 via the conveyor belt 6. After the exhaust fan 9 is started, negative pressure is generated through the exhaust pipe 8. The airflow is evenly distributed into the suction box 3 through the connecting square pipe 10, so that the multiple exhaust holes 4 form a uniform adsorption force on the fabric, ensuring that the fabric is flat and fixed on the surface of the conveyor belt 6. The first linear module 13 drives the moving beam 14 to move longitudinally, and the second linear module 15 drives the cutting head 16 to move laterally. The two work together to enable the cutting head 16 to move precisely along the preset path. The cutting head 16 integrates a punching knife 17, a cutting needle 18, and a cutting knife. 19 can complete multiple processing steps at once. The pressure plate 21 driven by the electric push rod 20 assists in fixing the edge of the fabric when moving. The peak displacement occurs. The felt conveyor belt 6 ensures both the stability of the fabric conveying and the negative pressure adsorption effect. The waste generated by cutting is transferred to the feeding rack 12 via the operating table 11. The waste is collected by rotating the receiving roller 1203 by the crank handle 1205. Throughout the process, the negative pressure adsorption system effectively suppresses cutting vibration and avoids fabric displacement. The air outlet grooves 22 on both sides of the support seat 1 maintain airflow circulation and ensure continuous and stable adsorption force.
