Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric processing technology, and in particular to a cutting device for nonwoven fabrics. Background Technology

[0002] Non-woven fabrics are characterized by moisture resistance, breathability, flexibility, light weight, non-flammability, easy decomposition, non-toxicity, non-irritation, rich colors, low price, and recyclability. Non-woven fabrics are widely used in all aspects of life and often require cutting. However, cutting with traditional scissors often leaves irregular cuts, affecting the tightness of the installation and resulting in an unsightly appearance.

[0003] Chinese patent application number 202223347212.6 discloses a utility model patent entitled "A Cutting Device for Nonwoven Fabric". This patent describes a method for cutting nonwoven fabric: the nonwoven fabric is placed between a base and a cutting seat, which clamp the fabric. A cutting blade pierces the fabric and presses against the base. The cutting blade is manually pushed to slide, cutting the fabric. Because the base and cutting seat clamp the fabric, it does not wrinkle under the action of the cutting blade.

[0004] In the aforementioned patent, when the non-woven fabric is placed between the base and the cutting seat, there is a lack of a positioning structure, which cannot guarantee that the non-woven fabric placed and fixed between the base and the cutting seat is perfectly regular (i.e., the end of the non-woven fabric is parallel to the base / seat clamp). This still results in the cut not conforming to the actual cutting requirements during cutting. Therefore, this utility model proposes a non-woven fabric cutting device to solve the above problems. Utility Model Content

[0005] To address the aforementioned problems, this utility model proposes a nonwoven fabric cutting device. By setting two roll positioning seats driven by a positioning drive mechanism in the first mounting seat at the top of the base plate, the nonwoven fabric roll can be positioned by the two roll positioning seats, thereby ensuring that the nonwoven fabric pulled from the nonwoven fabric roll always keeps its end parallel to the first mounting seat and the second mounting seat. This ensures that when the end of the nonwoven fabric is pressed and fixed inside the through groove for cutting, the cutting seam can be parallel to the second mounting seat, thus achieving high-quality cutting of nonwoven fabric.

[0006] To achieve the objectives of this utility model, the following technical solution is adopted:

[0007] A nonwoven fabric cutting device includes a base plate. A first mounting seat and a second mounting seat are respectively provided on the top two sides of the base plate. The first mounting seat is provided with a mounting groove. A positioning drive mechanism is provided in the mounting groove. A roll material positioning seat is symmetrically provided on the positioning drive mechanism. The top of the second mounting seat is provided with a moving groove. A cutting mechanism is slidably provided in the moving groove. The second mounting seat is provided with a through groove that communicates with the moving groove. A knife groove adapted to the position of the cutting mechanism is provided at the bottom of the through groove. Pressure plates are provided on both sides of the through groove. A locking drive mechanism connected to the pressure plates is provided on the top of the second mounting seat.

[0008] The roll positioning seat includes a seat body, a positioning post, and a guide roller. The seat body is connected to a positioning drive mechanism. The positioning post is provided on the inner side wall of the seat body. A groove is provided on the inner side wall of the seat body outside the positioning post. A guide roller is rotatably arranged in the groove. The guide roller has multiple side walls extending out of the groove.

[0009] A further improvement is that the cutting mechanism includes a mounting box and a cutting wheel. The mounting box is slidably connected to the moving groove. The cutting wheel is installed inside the mounting box via a mounting shaft, which is driven by a motor.

[0010] A further improvement is that the positioning drive mechanism includes a bidirectional lead screw and a drive source. The bidirectional lead screw is rotatably provided inside the mounting groove. The bidirectional lead screw is driven by the drive source. The seat is threadedly connected to the bidirectional lead screw, and the seat is slidably connected to the mounting groove.

[0011] A further improvement is that the locking drive mechanism includes a bracket, a locking screw, and a sleeve. The bracket is fixed to the top of the second mounting base, and the locking screw is rotatably mounted on the bracket. The top of the second mounting base is provided with a guide hole, and the sleeve is slidably mounted in the guide hole. The upper end of the sleeve is threadedly connected to the lower end of the locking screw, and the lower end of the sleeve is connected to the top of the pressure plate.

[0012] A further improvement is that a hollow protective tube is provided on the outside of the sleeve, and the two ends of the hollow protective tube are respectively connected to the bracket and the second mounting base.

[0013] A further improvement is that a fixed seat is provided on the top of the base plate between the first mounting seat and the second mounting seat, and a positioning roller is rotatably provided between the two fixed seats, the bottom position of the positioning roller being adapted to the bottom position of the through groove.

[0014] The beneficial effects of this utility model are as follows: By setting two roll positioning seats driven by a positioning drive mechanism in the first mounting seat at the top of the base plate, the non-woven fabric roll can be positioned by the two roll positioning seats, thereby ensuring that the non-woven fabric pulled out from the non-woven fabric roll always keeps its end parallel to the first mounting seat and the second mounting seat, so that when the end of the non-woven fabric is pressed and fixed in the through groove for cutting, the cutting seam can be parallel to the second mounting seat, thus achieving high-quality cutting of non-woven fabric.

[0015] The roll positioning seat of this utility model can be used to position the two ends of non-woven fabric rolls of different lengths after being driven by the positioning drive mechanism. The device is highly flexible in use. During the cutting process, the non-woven fabric is pressed and fixed by two pressure plates, which can ensure that wrinkles are not easily generated during cutting. Attached Figure Description

[0021] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0022] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a nonwoven fabric cutting device, including a base plate 1. A first mounting seat 2 and a second mounting seat 3 are respectively provided on the top two sides of the base plate 1. The first mounting seat 2 has a mounting groove 4, and a positioning drive mechanism is provided within the mounting groove 4. A roll material positioning seat is symmetrically provided on the positioning drive mechanism. The top of the second mounting seat 3 has a moving groove 5, and a cutting mechanism 6 is slidably disposed within the moving groove 5. The second mounting seat 3 has a through groove 7 inside, which communicates with the moving groove 5. The lower part of the through groove 7 is provided with a knife groove 8 adapted to the position of the cutting mechanism 6. Pressure plates 9 are provided on both sides of the through groove 7. The top of the second mounting base 3 is provided with a locking drive mechanism connected to the pressure plates 9. The roll positioning base includes a base body 10, a positioning post 11, and a guide roller 12. The base body 10 is connected to the positioning drive mechanism. The positioning post 11 is provided on the inner side wall of the base body 10. A groove is provided on the inner side wall of the base body 10 outside the positioning post 11. The guide roller 12 is rotatably mounted in the groove. The guide roller 12 has multiple side walls extending out of the groove. In this utility model, because the guide roller 12 extends out of the groove, when positioning the nonwoven fabric roll, the guide roller 12 will first limit contact with both ends of the nonwoven fabric roll. This arrangement allows the roll positioning base to achieve positioning and fixing of the nonwoven fabric roll while also ensuring that the unwinding of the nonwoven fabric roll is not interfered with by the rotating guide roller 12.

[0023] When the nonwoven fabric cutting equipment of this utility model is in operation, the roll of nonwoven fabric is placed into the first mounting base 2. Then, the positioning drive mechanism drives the two roll positioning seats to move relative to each other, so that the positioning post 11 is inserted into the center core of the nonwoven fabric roll until the end of the nonwoven fabric roll contacts the outer wall of the guide roller 12. At this time, the alignment and fixation of the nonwoven fabric roll is completed. Then, the end of the nonwoven fabric is pulled out to the bottom of the two pressure plates 9, so that the designated cutting position is located at the knife groove 8. The locking drive mechanism drives the pressure plate 9 to press down and fix the nonwoven fabric. Then, the cutting mechanism 6 is controlled to move in the moving groove 5 to realize the cutting.

[0024] A further improvement is that the cutting mechanism 6 includes a mounting box 601 and a cutting wheel 602. The mounting box 601 is slidably connected to the moving groove 5. The cutting wheel 602 is mounted inside the mounting box 601 via a mounting shaft, which is driven by a motor 603. When the motor 603 is started, it drives the cutting wheel 602 to rotate at high speed to achieve cutting. In this invention, the top of the mounting box 601 is provided with a handle, which facilitates the movement of the cutting mechanism 6 within the moving groove 5.

[0025] The positioning drive mechanism includes a bidirectional lead screw 13 and a drive source 14. The bidirectional lead screw 13 is rotatably mounted inside the mounting groove 4. The bidirectional lead screw 13 is driven by the drive source 14. The seat 10 is threadedly connected to the bidirectional lead screw 13 and slidably connected to the mounting groove 4. In this invention, the drive source 14 can be a geared motor or a manual drive. When the bidirectional lead screw 13 starts to rotate, the seat 10 moves synchronously relative to the mounting groove 4 and the bidirectional lead screw 13.

[0026] The locking drive mechanism includes a bracket 15, a locking screw 16, and a sleeve 17. The bracket 15 is fixed to the top of the second mounting base 3. The locking screw 16 is rotatably mounted on the bracket 15. The top of the second mounting base 3 has a guide hole, and the sleeve 17 is slidably mounted in the guide hole. The upper end of the sleeve 17 is threadedly connected to the lower end of the locking screw 16, and the lower end of the sleeve 17 is connected to the top of the pressure plate 9. A hollow protective tube 18 is provided on the outside of the sleeve 17, and both ends of the hollow protective tube 18 are connected to the bracket 15 and the second mounting base 3, respectively. When the locking drive mechanism of this utility model drives the pressure plate 9 to move, when the locking screw 16 is driven to rotate, the sleeve 17 slides in the guide hole, thereby driving the pressure plate 9 to press down and fix the non-woven fabric. The hollow protective tube 18 is provided to protect the locking screw 16.

[0027] A fixed seat is provided on the top of the base plate 1 between the first mounting seat 2 and the second mounting seat 3. A positioning roller 19 is rotatably provided between the two fixed seats. The bottom position of the positioning roller 19 is adapted to the bottom position of the through groove 7. By setting the positioning roller 19, the non-woven fabric can be pulled along the bottom of the through groove 7 when it enters the through groove 7. Specifically, one end of the non-woven fabric is introduced into the through groove 7 from the bottom of the positioning roller 19.

[0028] This invention features two roll positioning seats driven by a positioning drive mechanism within a first mounting seat at the top of the base plate. These two positioning seats position the nonwoven fabric roll, ensuring that the nonwoven fabric pulled from the roll always maintains its ends parallel to the first and second mounting seats. This ensures that when the nonwoven fabric ends are pressed and secured inside the through groove 7 for cutting, the cutting seam remains parallel to the second mounting seat, achieving high-quality cutting of the nonwoven fabric. The roll positioning seats, driven by the positioning drive mechanism, can position both ends of nonwoven fabric rolls of different lengths, offering high flexibility. During the cutting process, the nonwoven fabric is secured by two pressure plates 9, preventing wrinkles from forming during cutting.
