Description

Technical Field

[0001] This invention relates to the field of edge trimming technology, and more particularly to an edge trimming device for nylon fabric production. Background Technology

[0002] Nylon fabric is a synthetic fiber fabric with polyamide (PA) as its main component. It is widely used in the textile industry due to its excellent abrasion resistance, elasticity, and wrinkle resistance. Nylon fabric has high strength and toughness, is not easily broken, and also possesses good chemical resistance and mildew resistance, making it widely used in outdoor clothing, sports equipment, bags, parachutes, and other fields.

[0003] The edge-cutting method for nylon fabrics depends primarily on the application requirements and fabric characteristics. Because nylon fibers are slippery and prone to fraying, common edge-cutting methods include cold cutting, hot cutting, and laser cutting. Cold cutting is a traditional mechanical shearing method, but it easily produces burrs and loose threads; hot cutting uses a high-temperature blade to melt the fibers, sealing the edges and reducing fraying; laser cutting uses a high-energy beam to precisely melt the fibers, producing smooth and clean cuts, and can handle complex patterns, making it suitable for high-precision processing.

[0004] When cold-cutting nylon fabric, a large amount of debris and fibrous flakes are easily generated because the edges cannot be sealed during the cutting process. These debris accumulates continuously during the operation, causing contamination of the workbench, cutting equipment, and the surrounding environment, affecting production efficiency and ease of operation. In addition, if the debris is not cleaned up in time, it may adhere to the cut pieces, affecting subsequent sewing or bonding processes, and even impacting the quality of the finished product. Summary of the Invention

[0005] The purpose of this invention is to solve the problem of debris accumulation when cutting nylon fabric in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a nylon fabric production edge shearing device, comprising a support frame, and further comprising: a cutting disc rotatably mounted on the lower part of the support frame, wherein the cutting disc performs edge shearing on the passing nylon fabric when rotating; a guide frame disposed on the upper part of the collection bin, the guide frame being located below the support frame, the guide frame having an internal slot for collecting waste material, wherein when the cutting disc performs the shearing action, the sheared waste material falls through the slot of the guide frame into the upper part of the collection bin mounted on the ground; and a fan rotatably mounted on the support frame, wherein when the cutting disc rotates, the fan rotates synchronously, blowing the sheared waste material into the slot.

[0007] In at least some embodiments, guide rollers are rotatably mounted on both sides of the guide frame. When the nylon fabric passes through, it first passes under the guide roller on one side, then passes through the shearing area of ​​the guide frame, and finally passes under the guide roller on the other side.

[0008] In at least some embodiments, the upper part of the support frame is fixedly equipped with a support seat for fixing on a lift in the production workshop. When performing shearing operations, the lift controls the support frame and the cutting disc to descend and contact the nylon fabric for shearing.

[0009] In at least some embodiments, the output end of a motor fixedly mounted on one side of the support frame is fixedly connected to one end of a bidirectional lead screw rotatably mounted on the support frame. The outside of the bidirectional lead screw is screwed to two sliding plates slidably mounted inside the support frame. The cutting disc is rotatably mounted on the lower part of the sliding plate. The motor drives the two cutting discs to move closer and further apart to adapt to nylon fabrics of different widths.

[0010] In at least some embodiments, a square rod is rotatably mounted inside the support frame, and two fans are provided. The two fans, which are symmetrically arranged, are fixed to the outside of both sides of the square rod. The outside of the square rod is slidably connected to the cutting disc, and when the square rod rotates, it drives the cutting disc to rotate.

[0011] In at least some embodiments, a small gear fixed to the outside of the square rod meshes with a large gear rotatably mounted on the lower part of the support frame. A first roller is fixedly connected to one side of the large gear through the support frame. A large roller fixed to one end of one of the guide rollers is belt driven by a small roller fixed to one side of the second roller. When the guide frame descends, the second roller rotatably mounted on the guide frame presses against the first roller, thereby driving the cutting disc to rotate at a different speed.

[0012] In at least some embodiments, two cutting plates are slidably installed inside the guide frame, and the cutting disc is movably inserted into the blade groove of the cutting plate.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are as follows:

[0014] In this invention, a highly efficient and precise shearing mechanism improves the quality of nylon fabric edge trimming, ensures neat cutting, and avoids errors from manual cutting. Guide rollers stably transport the fabric, reducing wrinkles and improving shearing consistency. Simultaneously, a lifting mechanism adjusts the height of the cutting disc to accommodate fabrics of different thicknesses, expanding its applicability.

[0015] The cutting disc speed can be automatically adjusted according to the fabric conveying speed to achieve synchronous cutting, improve cutting accuracy and reduce losses. The fan rotates synchronously to blow the cutting debris into the collection bin, avoiding debris from flying and polluting the environment, reducing cleaning work and improving production efficiency.

[0016] The bidirectional lead screw adjusts the cutting disc distance to adapt to fabrics of different widths, making the device more flexible, reducing adjustment time, and improving processing efficiency.

[0017] The cutting disc blades insert into the guide frame's cutting plate grooves, improving shearing stability and effectively reducing debris splashing, resulting in cleaner sheared edges. The overall design optimizes the production environment, enhances equipment automation, reduces the need for manual intervention, and improves production efficiency and quality, making it suitable for large-scale nylon fabric processing.

[0023] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Implementation examples, based on Figures 1-4 ,like Figure 1As shown in the figure, an embodiment of the present invention provides a nylon fabric production edge shearing device, including a support frame 4, and further including: a cutting disc 5 rotatably installed at the lower part of the support frame 4. When the cutting disc 5 rotates, it performs edge shearing action on the passing nylon fabric. Specifically, when the device is running, the nylon fabric enters the shearing area under the guidance of the conveying mechanism or manual operation. The cutting disc 5 is installed at the lower part of the support frame 4 and rotates at a certain speed. When the fabric passes through the cutting disc 5, the sharp blades shear the edges, thereby removing irregular edges and making the fabric neat.

[0026] During the shearing process, nylon fabric debris and waste are inevitably generated. This waste needs to be cleaned up in a timely manner to prevent it from affecting the shearing effect and the working environment. A guide frame 1 is set on the upper part of the collection bin, located below the support frame 4. The guide frame 1 has an empty groove 2 for collecting waste inside. When the cutting disc 5 performs the shearing action, the sheared waste falls through the empty groove 2 of the guide frame 1 into the upper part of the collection bin installed on the ground. Specifically, after the cutting disc 5 finishes shearing the fabric, the cut waste naturally falls into the empty groove 2 of the guide frame 1, preventing debris from scattering into the working area. The fan 18 installed on the support frame 4 rotates synchronously when the cutting disc 5 rotates, blowing the sheared waste into the empty groove 2. When the cutting disc 5 is operating, the fan 18 generates airflow, blowing the debris towards the empty groove 2 of the guide frame 1, causing it to fall more concentratedly into the collection bin. The collection bin is located on the ground and is used to store these debris. Workers can clean it regularly to ensure the stability of continuous operation.

[0027] In this embodiment, guide rollers 10 are rotatably mounted on both sides of the guide frame 1. When the nylon fabric passes through, it first passes under the guide roller 10 on one side, then passes through the shearing area of ​​the guide frame 1, and finally passes under the guide roller 10 on the other side. When the nylon fabric enters the shearing device, it first passes under the guide roller 10 on one side. This guiding process ensures that the fabric is transported smoothly before shearing, preventing the shearing accuracy from being affected by looseness or wrinkles. When the fabric enters the shearing area, the cutting disc 5 rotates under the support frame 4 and adjusts its height under the control of the lifting mechanism to ensure appropriate shearing force.

[0028] The upper part of the support frame 4 is fixedly equipped with a support seat 3 for fixing on the lift in the production workshop. When performing the shearing operation, the lift controls the support frame 4 and the cutting disc 5 to descend and contact the nylon fabric for shearing. During the shearing operation, the lift controls the support frame 4 and the cutting disc 5 to move downward, so that the rotating cutting disc 5 contacts the nylon fabric and precisely cuts the rough edges. After shearing, the nylon fabric continues to be conveyed forward and passes under the guide roller 10 on the other side, so that the fabric leaves the shearing area smoothly, ensuring that the cut fabric is flat and wrinkle-free, which is convenient for subsequent processing.

[0029] By utilizing guide rollers 10 to effectively control the conveying path of nylon fabric, the stability of the shearing process is ensured. At the same time, the shearing height is adjusted by a lifting machine to improve adaptability, enabling the device to meet the shearing needs of nylon fabrics of different thicknesses and specifications, thereby improving shearing efficiency and quality.

[0030] In this embodiment, the output end of the motor 13, which is fixedly installed on one side of the support frame 4, is fixedly connected to one end of the bidirectional lead screw 14, which is rotatably installed on the support frame 4. When the motor 13 starts, it drives the bidirectional lead screw 14 to rotate. The outside of the bidirectional lead screw 14 is screwed to two sliding plates 15, which are slidably installed inside the support frame 4. The cutting disc 5 is rotatably installed on the lower part of the sliding plate 15. The motor 13 drives the two cutting discs 5 to move closer and further away, which is used to adapt to nylon fabrics of different widths. The outside of the bidirectional lead screw 14 is screwed to two sliding plates 15, which make it slide along the inside of the support frame 4. Since the thread structure of the bidirectional lead screw 14 is distributed in opposite directions, when the bidirectional lead screw rotates, the two sliding plates 15 will move in opposite directions at the same time, that is, move closer or further away from each other.

[0031] The cutting disc 5 is installed at the bottom of the slide plate 15. Therefore, the movement of the slide plate 15 directly changes the distance between the two cutting discs 5, thereby accommodating nylon fabrics of different widths. For wider fabrics, the cutting disc 5 can be adjusted to a farther position, while for narrower fabrics, the cutting disc 5 can be adjusted to a closer position, ensuring that the cutting area always matches the edge of the fabric, improving cutting accuracy and efficiency. This design not only enhances the flexibility of the equipment but also avoids the tedious operation of frequent manual adjustments, improving production efficiency and enabling the device to adapt to the processing needs of various specifications of nylon fabrics.

[0032] In this embodiment, a square rod 17 is rotatably mounted inside the support frame 4. Two fans 18 are provided, symmetrically arranged and fixed to the outside of both sides of the square rod 17. The outside of the square rod 17 is slidably connected to the cutting disc 5. When the square rod 17 rotates, it drives the cutting disc 5 to rotate. The square rod 17 not only supports the fans 18 but is also slidably connected to the cutting disc 5, meaning that the rotation of the square rod 17 can directly drive the movement of the cutting disc 5. A small gear 19 fixed to the outside of the square rod 17 meshes with a large gear 16 rotatably mounted on the lower part of the support frame 4. When the square rod 17 rotates, the small gear 19 drives the large gear 16 to rotate, thereby further transmitting power. One side of the large gear 16 passes through the support frame 4 and is fixedly connected to the cutting disc 5. A first roller 6 is attached. A large roller 8 fixed to one end of one of the guide rollers 10 is connected to a small roller 9 fixed to one side of the second roller 7 via belt drive. At the same time, the large roller 8 fixed to one end of a guide roller 10 is connected to the small roller 9 on one side of the second roller 7 via belt drive. The rotation of the small roller 9 will further drive the second roller 7 fixed on the guide frame 1. When the guide frame 1 descends, the second roller 7 and the first roller 6 make contact, so that the power is further transmitted to the first roller 6. The rotation of the first roller 6 will continue to drive the small gear 19 fixed to one side of it to rotate. The small gear 19 is a key component in the speed change mechanism and is meshed with the large gear 16 at the bottom of the support frame 4.

[0033] The rotation of the large gear 16 will eventually drive the cutting disc 5 and the fan 18. Since the cutting disc 5 is slidably connected to the square rod 17 and the square rod 17 is driven by the large gear 16, the rotation speed of the cutting disc 5 depends on the transmission ratio of the entire transmission chain. Similarly, the fan 18 is symmetrically installed on both sides of the square rod 17. Therefore, while the cutting disc 5 is rotating, the fan 18 also rotates synchronously, generating airflow to blow the cut nylon debris into the collection chamber.

[0034] As the guide frame 1 descends and the nylon fabric passes through the guide frame 1 and is conveyed forward, its tension exerts a force on the guide roller 10, causing the guide roller 10 to rotate with the fabric movement. The second roller 7, which is rotatably mounted on the guide frame 1, presses against the first roller 6. The rotation of the guide roller 10 drives the large rotating wheel 8 to rotate. Since the large rotating wheel 8 is connected to the small rotating wheel 9 through a belt drive, the small rotating wheel 9 rotates accordingly, further driving the second roller 7 to move. The rotational force of the first roller 6 is transmitted to the second roller 7, which in turn drives the cutting disc 5 to perform a variable speed rotation action. The rotational speed of the cutting disc 5 changes with the conveying speed of the nylon fabric, thereby ensuring that the cutting action is synchronized with the movement of the fabric and avoiding cutting errors.

[0035] Two cutting plates 11 are slidably installed inside the guide frame 1. The cutting disc 5 is movably inserted into the blade groove 12 of the cutting plate 11. When the cutting disc 5 rotates, its blade will enter the blade groove 12 of the cutting plate 11 to achieve precise cutting. This design not only improves the cutting accuracy, but also effectively reduces the splashing of debris and makes the cutting edge neater.

[0036] The working principle of this invention is as follows: Precise cutting of nylon fabric is achieved through a multi-stage transmission mechanism. After the nylon fabric enters the cutting area, it is first stably conveyed by guide rollers 10, and the height of the cutting disc 5 is adjusted under the control of a lifting machine to bring it into contact with the fabric for cutting. The cutting disc 5 rotates in linkage through a large gear 16, a small gear 19, and a square rod 17, efficiently cutting the rough edges. Simultaneously, a fan 18 operates synchronously, blowing debris into the slot 2 of the guide frame 1 for collection. When the nylon fabric pushes the guide rollers 10 to rotate, this power is adjusted via a transmission chain to adjust the speed and ultimately drive the cutting disc 5 to match the fabric conveying speed, ensuring cutting accuracy. The cutting disc 5 can slide along the bidirectional lead screw 14 to adjust the distance to accommodate fabrics of different widths. A cutting plate 11 is provided inside the guide frame 1, and the cutting blade of the cutting disc 5 is inserted into the blade slot 12 to enhance cutting accuracy and reduce debris splashing. This device integrates guiding, cutting, speed changing, and collection functions, ensuring stable and efficient cutting while improving debris handling capacity and enhancing the cleanliness of the production environment.

[0037] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
