Technical Field

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

[0002] Non-woven fabric refers to fabrics made of polyester fibers. Non-woven fabrics have the characteristics of being moisture-proof, breathable, flexible, lightweight, flame-retardant, non-toxic, odorless, inexpensive, and recyclable. Therefore, non-woven fabrics are widely used in many fields. During the production process, non-woven fabrics may have broken edges. In order to ensure that the non-woven fabrics are clean and flat during use, it is necessary to use an edge trimming machine to trim the edges of the non-woven fabrics before use.

[0003] Current nonwoven fabric edge cutting machines lack a pressing structure for the nonwoven fabric during use. Therefore, during the cutting process, the nonwoven fabric is prone to shifting, resulting in uneven cut edges, such as slanted cuts or cuts of varying widths, which cannot guarantee the cutting accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a nonwoven fabric edge-cutting device. This device is equipped with a pressure plate structure that moves synchronously with the cutting blade to press the nonwoven fabric, thereby solving the problems mentioned in the background art.

A spring is provided on the outer surface of the round rod. One end of the spring is fixedly connected to the lower surface of the support plate, and the other end of the spring is fixedly connected to the surface of the round rod. Four round rods are rectangularly distributed on the surface of the support plate. The lower ends of the four round rods are fixedly connected to the upper surface of the same pressure plate. The pressure plate has a square hollow structure and is located inside the cutting blade.

[0007] By employing the above technical solution, the nonwoven fabric can be pressed using the pressing structure, thus preventing the nonwoven fabric from shifting during the edge cutting process.

[0008] Preferably, the outer surface of the support plate is provided with a protective structure, which shields and protects the cutting blade through the protective plate.

[0009] By adopting the above technical solution, the cutting blade can be shielded and protected using the protective structure.

[0010] Preferably, the protective structure includes a protective plate with an L-shaped cross-section. The protective plate is slidably mounted on the outer surface of the support plate and is located outside the cutting blade.

[0011] By adopting the above technical solution, the protective plate installed on the outside of the cutting blade can protect the cutting blade and prevent injury to the operator.

[0012] Preferably, the lower surface of the support plate is provided with a smoothing structure, which uses a pressure roller to smooth the nonwoven fabric before cutting the edge, so as to prevent wrinkles from forming in the nonwoven fabric.

[0013] By using the above technical solution, the nonwoven fabric can be smoothed before cutting the edges using the scraping structure, thus avoiding wrinkles in the nonwoven fabric.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-5 This utility model provides a technical solution: a non-woven fabric edge cutting device, including a base 1, a top plate 2, a cylinder 3, a support plate 4, a cutting knife 5, a cutting table 6, a cutting groove 7, a round rod 8, a spring 9, a pressure plate 10, a protective plate 11, a support groove 12, and a pressure roller 13.

[0028] A top plate 2 is provided above the base 1. The base 1 and the top plate 2 are fixedly connected by a bracket. A cylinder 3 is fixedly installed on the surface of the top plate 2. The output end of the cylinder 3 passes through the surface of the top plate 2 and is connected to a support plate 4. A cutting blade 5 is fixedly connected to the lower surface of the support plate 4. The cutting blade 5 is long and narrow. Multiple cutting blades 5 form a U-shape on the lower surface of the support plate 4. A cutting table 6 is fixedly installed on the upper surface of the base 1. The cutting table 6 is aligned with the support plate 4 and has a trapezoidal structure. A cutting groove 7 is provided on the upper surface of the cutting table 6. The cutting groove 7 forms a U-shape on the upper surface of the cutting table 6 and is aligned with the lower end of the cutting blade 5. A protective structure is provided on the outer surface of the support plate 4. The protective structure shields and protects the cutting blade 5 through a protective plate 11. The protective structure includes a protective plate 11 with an L-shaped cross-section. The protective plate 11 is slidably installed on the outer surface of the support plate 4 and is located outside the cutting blade 5.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, when using this device, the non-woven fabric to be trimmed is placed on the cutting table 6 surface on the upper surface of the base 1, with the non-woven fabric surface aligned with the cutting groove 7 below. The cylinder 3 is activated, and the cylinder 3 drives the support plate 4 to move downward. As the support plate 4 drives the cutting blade 5 on the lower surface downward to align with the cutting groove 7, the non-woven fabric is trimmed. The trimmed non-woven fabric waste slides down the inclined surface of the trapezoidal platform. The protective plate 11 set on the outer surface of the support plate 4 provides protection from the outside of the cutting blade 5 when the device is idle, preventing the cutting blade 5 from injuring the operator. As the cutting blade 5 moves downward with the support plate 4, the support plate 4 drives the protective plate 11 to move downward synchronously. After the lower end of the protective plate 11 contacts the surface of the cutting table 6, it slides upward on the outer surface of the support plate 4 under the upward thrust of the cutting table 6, thereby preventing the protective plate 11 from obstructing the movement of the cutting blade 5.

[0030] The surface of the support plate 4 is provided with a pressing structure. The pressing structure prevents the non-woven fabric from shifting during the cutting process by the moving pressure plate 10. The pressing structure includes a round rod 8, which slides through the surface of the support plate 4. Both ends of the round rod 8 are provided with annular protrusions. A spring 9 is provided on the outer surface of the round rod 8. One end of the spring 9 is fixedly connected to the lower surface of the support plate 4, and the other end of the spring 9 is fixedly connected to the surface of the round rod 8. There are 4 round rods 8 rectangularly distributed on the surface of the support plate 4. The lower ends of the 4 round rods 8 are fixedly connected to the upper surface of the same pressure plate 10. The pressure plate 10 has a square hollow structure and is located inside the cutting blade 5.

[0031] like Figure 1 , Figure 2 and Figure 5As shown, when the support plate 4 drives the cutting blade 5 downwards to cut the edge, the support plate 4 drives the round rod 8 to move downwards synchronously. The pressure plate 10 on the lower surface of the round rod 8 first contacts the surface of the non-woven fabric. Under the action of the reaction force on the surface of the cutting table 6, the round rod 8 slides upwards on the surface of the support plate 4, while compressing the spring 9. Under the action of the round rod 8 and the pressure plate 10, the non-woven fabric is always tightly pressed against the surface of the cutting table 6 by the pressure plate 10 during the edge cutting process, thereby preventing the non-woven fabric from shifting during the edge cutting process.

[0032] The lower surface of the support plate 4 is provided with a smoothing structure. The smoothing structure uses a pressure roller 13 to smooth the non-woven fabric before cutting the edge, so as to prevent wrinkles from appearing on the non-woven fabric. The smoothing structure includes a support groove 12, which is provided on the lower surface of the support plate 4. The cross-section of the support groove 12 is an inverted trapezoidal structure. The inner wall of the support groove 12 is rotatably connected to the pressure roller 13 through a bracket. The connecting bracket of the pressure roller 13 contacts the inclined side of the trapezoidal support groove 12. Two sets of support grooves 12 and pressure rollers 13 are symmetrically arranged on the surface of the support plate 4.

[0033] like Figure 1 and Figure 4 As shown, when the support plate 4 moves downward to cut the edge of the cutting blade 5, the pressure roller 13 on the lower surface of the support plate 4 comes into contact with the non-woven fabric. The support bracket connecting the pressure roller 13 and the support groove 12 rotates. The pressure roller 13 rotates in the direction of the support groove 12. During the rotation, the pressure rollers 13 on both sides press the non-woven fabric outward to flatten it, so as to avoid wrinkles in the non-woven fabric before cutting the edge.

[0034] Working principle: When using this nonwoven fabric trimming device, place the nonwoven fabric on the surface of the cutting table 6, start the cylinder 3, and use the cylinder 3 to drive the support plate 4 to move downward. The support plate 4 drives the cutting blade 5 downward to trim the nonwoven fabric. The protective plate 11 on the outer surface of the cutting blade 5 provides protection to prevent the cutting blade 5 from injuring the operator. The support plate 4 simultaneously drives the round rod 8 and the pressure roller 13 to move downward. The pressure rollers 13 on both sides press the nonwoven fabric outward to flatten it and prevent wrinkles. At the same time, the round rod 8 drives the pressure plate 10 downward to press the nonwoven fabric onto the surface of the cutting table 6, preventing the nonwoven fabric from shifting during the trimming process and increasing the overall practicality.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
