Description

Technical Field

[0001] This utility model relates to a fabric cutting device, belonging to the field of fabric cutting technology. Background Technology

[0002] In the fabric processing and production process, fabric cutting is a crucial step. Fabric cutting devices achieve the cutting and separation of fabric through the relative movement of the cutting blade and the fabric, and are widely used in clothing manufacturing, home textile production, and other fields. However, after long-term use, existing fabric cutting devices tend to leave fabric fibers, lint, or other impurities on the blade and blade surface after cutting the fabric. This is mainly because fabric itself is mostly woven from fibers. During the cutting process, the fibers are subjected to the shearing force of the blade, and some fibers adhere to the surface of the cutting blade due to friction, electrostatic adsorption, etc. If these residual impurities are not cleaned in time, they will accumulate with each cut, potentially affecting the direct contact between the cutting blade and the fabric. This can lead to problems such as rough fabric edges, uneven cuts, or even blade jamming during subsequent cuts, reducing product quality and cutting efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a fabric cutting device that solves the problem that in the long-term use of existing fabric cutting devices, after the cutting blade completes the cutting of the fabric, the blade and the surface of the blade body are prone to residual fabric fibers, lint or other impurities. With the increase of the number of cuts, the impurities will continue to accumulate, which may affect the direct contact between the cutting blade and the fabric, resulting in rough edges of the fabric, uneven cutting or even blade jamming during subsequent cutting, thereby reducing product quality and cutting efficiency.

[0004] The technical problem to be solved by this utility model is achieved by the following technical solution: a fabric cutting device, including a placement plate, a support frame fixedly mounted on the placement plate, an mounting plate mounted on the side of the support frame facing the placement plate, a driving structure for driving the mounting plate mounted on the support frame, a cutting blade fixedly mounted on the side of the mounting plate away from the support frame, a scraper mounted on the mounting plate, and a pushing structure for pushing the scraper mounted on the mounting plate, wherein the scraper can abut against the cutting blade.

[0005] By adopting the above technical solution, the fabric to be cut is first placed on the placement plate, then the drive structure is activated to move the mounting plate, and then the mounting plate moves the cutting blade. The cutting blade cuts the fabric. After the fabric is cut, the push structure moves the scraper towards the cutting blade, so that the scraper cleans the impurities attached to the outer surface of the cutting blade. By cleaning the cutting blade with the scraper, the cutting blade can be kept clean in real time, ensuring stable contact between the cutting blade and the fabric during the next cut, avoiding uneven cutting and blade jamming problems, and effectively improving product quality.

[0006] The present invention is further configured such that: the driving structure includes a sliding groove, a motor, a threaded rod and a sliding block, the sliding groove is opened on the support frame, the sliding block is slidably disposed inside the sliding groove, the motor is fixedly disposed on the support frame, the threaded rod is poweredly connected to the motor, and one end of the threaded rod extends into the interior of the sliding groove and is threadedly connected to the sliding block.

[0007] The present invention is further configured such that: the pushing structure includes a positioning groove, a positioning block, a lever plate and a first spring, the positioning groove is formed on the mounting plate, the positioning block is slidably disposed inside the positioning groove, the lever plate is fixedly disposed with the positioning block, one end of the lever plate away from the positioning block extends to the outside of the mounting plate, and the first spring is fixedly disposed between the positioning block and the positioning groove.

[0008] The present invention is further configured such that: a limiting hole is provided on the dial plate, an inner groove communicating with the positioning groove is provided on the mounting plate, a limiting ball is slidably provided inside the inner groove, and a second spring is fixedly provided between the limiting ball and the inner groove.

[0009] The present invention is further configured such that: a connecting plate is fixedly provided on the positioning block, a protective cover is provided on one side of the connecting plate, and a moving structure for pushing the protective cover is provided on the connecting plate.

[0010] The present invention is further configured such that: the movable structure includes a connecting groove, a connecting block, an adjusting rod, and a rotating block; the connecting groove is formed on the connecting plate; the connecting block is slidably disposed inside the connecting groove; one end of the connecting block extends to the outside of the connecting plate and is fixedly connected to the protective cover; the adjusting rod is rotatably disposed on the connecting plate; one end of the adjusting rod extends to the inside of the connecting groove and is threadedly connected to the connecting block; the other end of the adjusting rod extends to the outside of the connecting plate and is fixedly connected to the rotating block.

[0011] By adopting the above technical solution, when the lever moves, it synchronously drives the limiting hole to move towards the inner groove. When the lever abuts against the limiting ball, the limiting ball slides into the inner groove under the action of abutment. During the sliding process, the second spring is compressed. When the limiting hole is aligned with the inner groove, the second spring resets and pushes the limiting ball to move towards the limiting hole. At this time, the limiting ball is inserted into the interior of the limiting hole, thus completing the limiting of the lever and the scraper. During the movement of the positioning block, it synchronously drives the connecting plate to move, causing the connecting plate to move the protective cover. When the limiting ball is inserted into the interior of the limiting hole, the protective cover is aligned with the cutting blade. Then, rotating the rotating block drives the adjusting rod to rotate. Under the action of the threaded structure, the adjusting rod drives the connecting block to slide in the connecting groove, causing the connecting block to move the protective cover towards the cutting blade, realizing the protection of the cutting blade by the protective cover. The protective cover protects the cutting blade, avoiding collisions between the operator and the cutting blade when not in use, and improving the installation performance of the device.

[0012] The beneficial effects of this utility model are as follows: First, the fabric to be cut is placed on the placement plate. Then, the drive structure is activated to move the mounting plate. The mounting plate then moves the cutting blade, which cuts the fabric. After the fabric is cut, the push structure moves the scraper towards the cutting blade, allowing the scraper to clean the impurities attached to the outer surface of the cutting blade. By cleaning the cutting blade with the scraper, the cutting blade can be kept clean in real time, ensuring stable contact between the cutting blade and the fabric during the next cut. This avoids uneven cutting and blade jamming, effectively improving product quality. Attached Figure Description

[0021] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0022] like Figures 1 to 4As shown, a fabric cutting device includes a placement plate 1 for placing the fabric to be cut. A support frame 2 is fixedly mounted on the placement plate 1. A mounting plate 3 is mounted on the side of the support frame 2 facing the placement plate 1. A driving structure for driving the mounting plate 3 is provided on the support frame 2. A cutting blade 4 is fixedly mounted on the side of the mounting plate 3 away from the support frame 2. A scraper 5 is provided on the mounting plate 3.

The scraper 5 can abut against the cutting blade 4.

[0023] like Figure 2 As shown, the drive structure includes a sliding groove 1011, a motor 1012, a threaded rod 1013, and a sliding block 1014. The sliding groove 1011 is horizontally opened on the support frame 2. The sliding block 1014 is slidably disposed inside the sliding groove 1011 and moves along the opening direction of the sliding groove 1011. The motor 1012 is fixedly disposed on the support frame 2 and is connected to an external power source to provide power to the motor 1012. The threaded rod 1013 is poweredly connected to the motor 1012. One end of the threaded rod 1013 extends into the interior of the sliding groove 1011 and is threadedly connected to the sliding block 1014. The end of the threaded rod 1013 away from the motor 1012 is rotatably connected to the inner wall of the sliding groove 1011.

[0024] like Figure 4 As shown, the pushing structure includes a positioning groove 1021, a positioning block 1022, a lever 1023, and a first spring 1024. The positioning groove 1021 is vertically formed on the mounting plate 3. The positioning block 1022 is slidably disposed inside the positioning groove 1021 and moves along the direction of the positioning groove 1021. The lever 1023 is fixedly disposed with respect to the positioning block 1022. One end of the lever 1023 away from the positioning block 1022 extends to the outside of the mounting plate 3. The first spring 1024 is fixedly disposed between the positioning block 1022 and the positioning groove 1021. The first spring 1024 is in a tensioned state when it is not under force.

[0025] like Figure 4 and Figure 5 As shown, a limiting hole 1031 is provided on the dial plate 1023, and an inner groove 1032 communicating with the positioning groove 1021 is provided on the mounting plate 3. The opening direction of the inner groove 1032 is the same as the opening direction of the sliding groove 1011. A limiting ball 1033 is slidably provided inside the inner groove 1032. A second spring 1034 is fixedly provided between the limiting ball 1033 and the inner groove 1032. The second spring 1034 is in a tensioned state when it is not under force.

[0026] like Figure 6 and Figure 7As shown, a connecting plate 1041 is fixedly installed on the positioning block 1022. There are two connecting plates 1041. A protective cover 1042 is provided on one side of each of the two connecting plates 1041. A moving structure for pushing the protective cover 1042 is provided on the connecting plate 1041.

[0027] like Figure 7 As shown, the movable structure includes a connecting groove 1051, a connecting block 1052, an adjusting rod 1053, and a rotating block 1054. The connecting groove 1051 is formed on the connecting plate 1041. The connecting block 1052 is slidably disposed inside the connecting groove 1051. One end of the connecting block 1052 extends to the outside of the connecting plate 1041 and is fixedly connected to the protective cover 1042. The adjusting rod 1053 is rotatably disposed on the connecting plate 1041. One end of the adjusting rod 1053 extends to the inside of the connecting groove 1051 and is threadedly connected to the connecting block 1052. The other end of the adjusting rod 1053 extends to the outside of the connecting plate 1041 and is fixedly connected to the rotating block 1054. Another connecting plate 1041 also has a guide groove. A guide rod is fixedly disposed inside the guide groove. A guide block is also disposed inside the guide groove. The guide rod passes through the guide block. One end of the guide block extends to the outside of the connecting plate 1041 and is fixedly connected to the protective cover 1042. The guide block and the connecting block 1052 move synchronously. The guide block and guide groove work together to limit and guide the protective cover 1042, preventing the protective cover 1042 from shifting during movement.

[0028] First, the fabric to be cut is placed on the placement plate 1. Then, the motor 1012 is started to drive the threaded rod 1013 to rotate. Under the action of the threaded structure, the threaded rod 1013 drives the sliding block 1014 to slide in the sliding groove 1011, causing the sliding block 1014 to move the mounting plate 3. Then, the mounting plate 3 drives the cutting blade 4 to move, and the cutting blade 4 cuts the fabric. After the fabric is cut, the push plate 1023 drives the positioning block 1022 to slide in the positioning groove 1021. During the movement, the positioning block 1022 compresses the first spring 1024, causing the positioning block 1022 to drive the scraper 5 to move towards the cutting blade 4. The scraper 5 cleans the impurities attached to the outer surface of the cutting blade 4. By cleaning the cutting blade 4 with impurities by the scraper 5, the cutting blade 4 can be kept clean in real time, ensuring stable contact between the cutting blade 4 and the fabric during the next cut, avoiding uneven cutting and blade jamming problems, and effectively improving product quality.

[0029] When the lever 1023 moves, it synchronously drives the limiting hole 1031 to move towards the inner groove 1032. When the lever 1023 abuts against the limiting ball 1033, the limiting ball 1033 slides into the inner groove 1032 under the action of abutment. During the sliding process, the second spring 1034 is compressed. When the limiting hole 1031 is aligned with the inner groove 1032, the second spring 1034 resets and pushes the limiting ball 1033 to move towards the limiting hole 1031, so that the limiting ball 1033 is inserted into the interior of the limiting hole 1031, thus completing the limiting of the lever 1023, thereby completing the limiting of the scraper 5.

[0030] During its movement, the positioning block 1022 synchronously drives the connecting plate 1041 to move, which in turn drives the protective cover 1042 to move. When the limiting ball 1033 is inserted into the limiting hole 1031, the protective cover 1042 is aligned with the cutting blade 4. Then, the rotating block 1054 drives the adjusting rod 1053 to rotate. Under the action of the threaded structure, the adjusting rod 1053 drives the connecting block 1052 to slide in the connecting groove 1051, so that the connecting block 1052 drives the protective cover 1042 to move towards the cutting blade 4. This achieves the protection of the cutting blade 4 by the protective cover 1042. By protecting the cutting blade 4 with the protective cover 1042, the collision between the operator and the cutting blade 4 is avoided when the device is not in use, thus improving the installation performance of the device.

[0031] When the fabric needs to be cut, first rotate the rotating block 1054 to drive the adjusting rod 1053 to rotate. Under the action of the threaded structure, the adjusting rod 1053 drives the connecting block 1052 to slide in the connecting groove 1051, so that the connecting block 1052 drives the protective cover 1042 to move away from the cutting blade 4, thereby canceling the protection of the cutting blade 4 by the protective cover 1042. Then push the dial plate 1023 to slide in the positioning groove 1021, so that the dial plate 1023 drives the limiting hole 1031 and the limiting ball 103. 3. When the ball 1033 abuts, it slides into the inner groove 1032 under the action of abutting. During the sliding process, the ball 1033 compresses the second spring 1034, which cancels the limitation between the ball 1033 and the limiting hole 1031, thereby canceling the limitation of the counter plate 1023. At this time, the first spring 1024 resets and drives the positioning block 1022 to slide in the positioning groove 1021, so that the positioning block 1022 drives the scraper 5 to move away from the cutting blade 4, which can cut the fabric.
