Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and in particular to a fabric cutting device that ensures cutting accuracy. Background Technology

[0002] Fabric cutting devices are a type of mechanical equipment widely used in garment processing, mask production, and other fields. Their main function is to precisely cut fabric to meet the production needs of different products. Fabric cutting devices play an important role in modern textile and garment processing and mask production. With continuous technological progress and innovation, future fabric cutting devices will be more intelligent, efficient, and environmentally friendly, providing strong support for the development of related industries. In order to achieve effective cutting accuracy, we need to use fabric cutting devices that guarantee cutting precision.

[0003] According to the description in the fabric cutting device published on the patent website (authorization announcement number: CN 211596170 U), "This utility model provides a fabric cutting device, belonging to the field of fabric cutting technology, including a mounting frame assembly, a first rotating shaft, a second rotating shaft, and a support plate. The mounting frame assembly is U-shaped. The first rotating shaft is rotatably mounted on the mounting frame assembly, and the first rotating shaft is provided with two first washers and a first cutting wheel located between the two first washers. The second rotating shaft is rotatably mounted on the mounting frame assembly, and the second rotating shaft is provided with two second cutting wheels and a second washer located between the two second cutting wheels. The outer walls of the two second cutting wheels respectively contact the outer walls of the two first washers and are matched in length. The second washer contacts the outer wall of the first cutting wheel and is matched in length. Both ends of the first and second cutting wheels are provided with cutting blades on their outer edges."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this invention places the fabric on a support plate. Upon contact with the first or second cutting wheel, the fabric moves forward due to friction between the first and second cutting wheels (either the first or second cutting wheel) as the first shaft rotates. The length of the first and second cutting wheels determines the width of the cut fabric strip. However, due to variations in fabric thickness, excessively thick fabric may become stuck in the blades during cutting. This sticking can damage the machine during rotation, affecting the cutting effect. Therefore, an improved fabric cutting device with enhanced cutting precision is needed to address these issues. Utility Model Content

[0006] To overcome the problem that fabric cutting devices that ensure cutting accuracy may cause fabric to get stuck inside the blade during cutting due to variations in fabric thickness, which can damage the machine and affect the cutting effect.

[0007] The technical solution of this utility model is as follows: a fabric cutting device that ensures cutting accuracy, including a processing base, a fixed connecting rod, and a limiting component. A support platform is fixedly connected inside the processing base, and a fixed mounting seat is movably connected inside the processing base. A fixing bolt is threaded inside the fixed mounting seat, and a first cutting wheel is provided inside the fixed mounting seat. A rotating handle is provided on the right side of the processing base. The limiting component is located inside the support platform. A limiting support rod is fixedly connected inside the fixed mounting seat. The fixed connecting rod is fixedly connected inside the fixed mounting seat. A sliding limiting block is slidably connected outside the fixed connecting rod. The sliding limiting block is slidably connected outside the limiting support rod. A first spring is fixedly connected between the sliding limiting block and the fixed mounting seat.

[0008] Preferably, there are two limit support rods, and the two limit support rods are symmetrically fixedly connected inside the fixed mounting base.

[0009] Preferably, the fixed mounting base has a groove at the corresponding position of the sliding limit block, and the sliding limit block slides inside the groove.

[0010] Preferably, a rotating connecting rod is fixedly connected to the left side of the rotating handle, a first gear is fixedly connected to the outside of the rotating connecting rod, a rotating connecting shaft is rotatably connected inside the fixed mounting base, a second gear is fixedly connected to the outside of the rotating connecting shaft, the second gear meshes with the outside of the first gear, and a second cutting wheel is fixedly connected to the outside of the rotating connecting shaft.

[0011] Preferably, the interior of the second cutting wheel has a cutting groove at the position corresponding to the blade of the first cutting wheel, and the blade rotates inside the cutting groove.

[0012] Preferably, the limiting component includes a drive motor, which is fixedly connected to the right side of the support platform. The output end of the drive motor is fixedly connected to a bidirectional threaded rod. A threaded connecting plate is threadedly connected to the outside of the bidirectional threaded rod. A sliding limiting rod is slidably connected inside the threaded connecting plate. A support connecting plate is fixedly connected to the inner front side of the sliding limiting rod. A return spring is fixedly connected between the support connecting plate and the bidirectional threaded rod. A limiting ring is fixedly connected to the outside of the sliding limiting rod.

[0013] Preferably, there are two sliding limit rods, and the two sliding limit rods are symmetrically slidably connected inside the bidirectional threaded rod.

[0014] The beneficial effects of this utility model are as follows: Compared with cutting wheels that cannot cut fabrics of different thicknesses, the sliding limit block is pushed by the first spring to slide downward inside the fixed mounting base under the limitation of the fixed connecting rod and the limit support rod. The downward sliding of the sliding limit block drives the first cutting wheel to squeeze and cut the fabric, thus achieving effective cutting of fabrics of different thicknesses, ensuring the safety of equipment use, improving the cutting effect of the equipment on fabrics, and effectively preventing the fabric that is too thick from getting stuck inside the blade and causing damage to the machine during cutting.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 - Figure 5This utility model provides an embodiment of a fabric cutting device that ensures cutting accuracy. The device includes a processing base 1, a fixed connecting rod 801, and a limiting component. A support platform 2 is fixedly connected inside the processing base 1. A fixed mounting seat 3 is movably connected inside the processing base 1. A fixing bolt 4 is threadedly connected inside the fixed mounting seat 3. A first cutting wheel 5 is disposed inside the fixed mounting seat 3. A rotating handle 6 is disposed on the right side of the processing base 1. The limiting component is disposed inside the support platform 2. A limiting support rod 802 is fixedly connected inside the fixed mounting seat 3. The fixed connecting rod 801 is fixedly connected inside the fixed mounting seat 3. A sliding limiting block 803 is slidably connected outside the fixed connecting rod 801. The sliding limiting block 803 is slidably connected outside the limiting support rod 802. A first spring 804 is fixedly connected between the sliding limiting block 803 and the fixed mounting seat 3. The fixing bolt 4 is used to fix the fixed mounting seat 3 to the processing base 1. Inside the base 1, the first cutting wheel 5 cuts the fabric. The support platform 2 holds the fabric. The first spring 804 pushes the sliding limit block 803 to slide downward inside the fixed mounting base 3 under the limitation of the fixed connecting rod 801 and the limit support rod 802. The downward sliding of the sliding limit block 803 drives the first cutting wheel 5 to squeeze and cut the fabric. There are two limit support rods 802, which are symmetrically fixedly connected inside the fixed mounting base 3. The two limit support rods 802 make the sliding limit block 803 more stable when sliding inside the fixed mounting base 3. The fixed mounting base 3 has a groove at the corresponding position of the sliding limit block 803. The sliding limit block 803 slides inside the groove. The groove at the corresponding position of the sliding limit block 803 inside the fixed mounting base 3 limits the sliding limit block 803 when it slides inside the groove.

[0024] Please see Figure 3 - Figure 4In this embodiment, a rotating connecting rod 805 is fixedly connected to the left side of the rotating handle 6. A first gear 806 is fixedly connected to the outside of the rotating connecting rod 805. A rotating connecting shaft 807 is rotatably connected inside the fixed mounting base 3. A second gear 808 is fixedly connected to the outside of the rotating connecting shaft 807. The second gear 808 meshes with the outside of the first gear 806. A second cutting wheel 809 is fixedly connected to the outside of the rotating connecting shaft 807. By manually rotating the rotating handle 6, the rotating connecting rod 805 is driven to rotate inside the fixed mounting base 3. The rotation of the rotating connecting rod 805 drives the first gear 806 and the second gear 808 to mesh and rotate. The rotation of the second gear 808 drives the second cutting wheel 809 outside the rotating connecting shaft 807 to rotate, which plays a role in conveying the fabric to the inside of the first cutting wheel 5 for cutting. The inside of the second cutting wheel 809 has a cutting groove at the corresponding position of the blade of the first cutting wheel 5. The blade rotates inside the cutting groove. The cutting groove inside the second cutting wheel 809, corresponding to the position of the first cutting wheel 5, makes the blade more stable when cutting the fabric.

[0025] Please see Figure 5 - Figure 6 In this embodiment, the limiting component includes a drive motor 901, which is fixedly connected to the right side of the support platform 2. A bidirectional threaded rod 902 is fixedly connected to the output end of the drive motor 901. A threaded connecting plate 903 is threadedly connected to the external side of the bidirectional threaded rod 902. A sliding limiting rod 904 is slidably connected inside the threaded connecting plate 903. A support connecting plate 905 is fixedly connected to the inner front side of the sliding limiting rod 904. A return spring 906 is fixedly connected between the support connecting plate 905 and the bidirectional threaded rod 902. The outer side of 04 is fixedly connected to a limiting ring 907. The bidirectional threaded rod 902 is driven to rotate by a drive motor 901. Under the condition that the bidirectional threaded rod 902 is threadedly connected to the sliding limiting rod 904, the rotation of the bidirectional threaded rod 902 will drive the threaded connecting plate 903 to move. There are two sliding limiting rods 904, and the two sliding limiting rods 904 are symmetrically slidably connected inside the bidirectional threaded rod 902. The two sliding limiting rods 904 make the support connecting plate 905 more stable when squeezing the fabric.

[0026] During operation, the fabric is first placed on top of the support platform 2. The drive motor 901 drives the bidirectional threaded rod 902 to rotate. Due to the threaded connection between the bidirectional threaded rod 902 and the sliding limit rod 904, the rotation of the bidirectional threaded rod 902 causes the threaded connecting plate 903 to move. The movement of the threaded connecting plate 903 pushes the support connecting plate 905 to limit the width of the fabric. During this limiting process, the sliding limit rod 904, under the limitation of the limit ring 907, slides inside the bidirectional threaded rod 902 to absorb shock. During cutting... The rotating connecting rod 805 rotates, causing the first gear 806 and the second gear 808 to mesh and rotate. The rotation of the second gear 808 drives the second cutting wheel 809 outside the rotating connecting shaft 807 to rotate, which plays a role in conveying the fabric and feeding the fabric into the first cutting wheel 5 for cutting. In order to achieve an effective cutting effect, the first spring 804 pushes the sliding limit block 803 to slide downward inside the fixed mounting base 3 under the limit of the fixed connecting rod 801 and the limit support rod 802. The downward sliding of the sliding limit block 803 drives the first cutting wheel 5 to squeeze and cut the fabric.

[0027] Through the above steps, the first spring 804 pushes the sliding limit block 803 to slide downward inside the fixed mounting base 3 under the limitation of the fixed connecting rod 801 and the limit support rod 802. The downward sliding of the sliding limit block 803 drives the first cutting wheel 5 to squeeze and cut the fabric. This solves the problem that when the fabric cutting device is cutting the fabric with guaranteed cutting accuracy, the thickness of the fabric varies. If the fabric is too thick, it may easily get stuck inside the blade during cutting. The stuck fabric may damage the machine when it is rotating, affecting the cutting effect of the equipment.
