Technical Field

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

[0002] Spunlace nonwoven fabric is a nonwoven material made by injecting a fiber web with high-pressure water jets, causing the fibers to entangle and strengthen each other. It features softness, breathability, high strength, no lint, and no chemical adhesives, and is widely used in medical, hygiene, cleaning, and industrial fields. Its production process is gentle, compatible with various fibers, and the finished product combines the feel and functionality of a fabric.

[0003] In the production and processing of spunlace nonwoven fabrics, the cutting process is crucial, as its quality and efficiency directly affect the production and use of subsequent products. Currently, most existing spunlace nonwoven fabric cutting devices have some problems. For example, some devices lack effective intermittent conveying control when transporting spunlace nonwoven fabrics, which can easily lead to stretching and wrinkling of the nonwoven fabrics during the cutting process, affecting the cutting accuracy. Some cutting devices also have unreasonable cutting blade movement patterns, which cannot be well coordinated with the conveying of nonwoven fabrics, reducing cutting efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figure 1-6 A cutting device for spunlace nonwoven fabric processing includes a mounting frame 1. A conveying mechanism is installed within the mounting frame 1 to intermittently transport the spunlace nonwoven fabric, facilitating its cutting. A cutting mechanism is also installed on the mounting frame 1 to drive a cutting blade 22 in a vertical reciprocating motion, further aiding in the intermittent transport of the nonwoven fabric and protecting the cutting blade 22 with the cushioning provided by a spring 27. The conveying mechanism includes a first conveyor belt assembly 31 and a second conveyor belt assembly 33, used for transporting the spunlace nonwoven fabric. The first conveyor belt assembly 31 includes a first driving wheel and a first driven wheel, both rotatably connected to the inner wall of the mounting frame 1 and meshing with each other. The first conveyor belt is connected to the second conveyor belt assembly 33, which includes a second driving wheel and a second driven wheel. Both the second driving wheel and the second driven wheel are rotatably connected to the inner wall of the mounting frame 1. The second conveyor belt is meshed with the second driving wheel and the second driven wheel. One end of the driving wheel of the first conveyor belt assembly 31 penetrates the surface of the mounting frame 1, and one end of the driven wheel of the second conveyor belt assembly 33 penetrates the surface of the mounting frame 1. One end of the driving wheel of the first conveyor belt assembly 31 is connected to one end of the driven wheel of the second conveyor belt assembly 33 through a track mechanism 32. By providing the track mechanism 32, when the second conveyor belt assembly 33 is in motion, it drives the first conveyor belt assembly 31 to move. A cutting table 311 is provided on the inner wall of the mounting frame 1. The cutting table 311 is provided to receive the cutting of the cutting blade 22. The cutting table 311 is located between the first conveyor belt assembly 31 and the second conveyor belt assembly 33.

[0024] The cutting mechanism includes two slide rods 26, which are fixedly installed on the surface of the mounting frame 1. The slide rods 26 are used to limit the position of the frame 24. The frame 24 is slidably mounted on the slide rods 26, and two buffer rods 25 are slidably mounted on the frame 24. The buffer rods 25 are cylindrical in shape, and a cutting blade 22 is fixedly mounted at the bottom of the buffer rod 25. The cutting blade 22 is used to cut the spunlace nonwoven fabric.

[0025] In detail, a mounting base 34 is fixedly installed on the mounting bracket 1. The mounting base 34 is L-shaped and is used to support the installation of the first motor 310. The first motor 310 is fixedly installed on the inner wall of the mounting base 34 and is used to drive the drive rod 39 to perform circular motion.

[0026] Furthermore, a drive rod 39 is fixedly installed on the shaft end of the first motor 310. The drive rod 39 is L-shaped and cylindrical at the end. A limit plate 38 is fixedly installed on the drive rod 39. The limit plate 38 is designed to slide within the limit groove 35, thereby achieving the purpose of limiting and fixing the receiving block 37.

[0027] Furthermore, one end of the drive wheel of the second conveyor belt assembly 33 passes through the mounting frame 1 and is fixedly mounted with a receiving block 37. The receiving block 37 is designed to support the opening of the drive groove 36 and the limiting groove 35. The surface of the receiving block 37 is provided with drive grooves 36 and limiting grooves 35, and there are four drive grooves 36 and four limiting grooves 35. The drive grooves 36 are designed to support the insertion of the drive rod 39, and the limiting grooves 35 are designed to support the sliding of the limiting plate 38.

[0028] More specifically, a spring 27 is fixedly installed at the top of the frame 24. The spring 27 is wound around the buffer rod 25. A horizontal plate 28 is fixedly installed at the top of the buffer rod 25. The top of the spring 27 is connected to the bottom of the horizontal plate 28. The spring 27 serves to buffer the cutting blade 22.

[0029] In general, a bracket 21 is fixedly installed on the mounting frame 1. The bracket 21 is arched in shape. A second motor 210 is fixedly installed on the bracket 21. The second motor 210 is used to drive the turntable 29 to rotate.

[0030] Finally, a turntable 29 is fixedly installed on the shaft end of the second motor 210. The turntable 29 is designed to drive the limiting rod 23 to perform circular motion. The limiting rod 23 is fixedly installed on the turntable 29. The limiting rod 23 is cylindrical in shape and is set horizontally. The limiting rod 23 slides on the inner wall of the frame 24. The limiting rod 23 is designed to drive the frame 24 to slide vertically along the surface of the slide rod 26.

[0031] Working method: During operation, the spunlace nonwoven fabric to be cut is placed on the second conveyor belt assembly 33. Then, the first motor 310 is started, driving the drive rod 39 to perform circular motion. When the drive rod 39 is inserted into the drive groove 36 on the surface of the receiving block 37, it will drive the receiving block 37 to rotate until the drive rod 39 leaves the drive groove 36. At this time, the limiting plate 38, driven by the drive rod 39, will rotate into the limiting groove 35 of the receiving block 37, thus limiting and fixing the receiving block 37 until the drive rod 39... When the device moves back to the drive groove 36, the receiving block 37 will rotate again. This arrangement facilitates the intermittent rotation of the receiving block 37. When the receiving block 37 rotates intermittently, it drives the drive wheel of the second conveyor belt assembly 33 to perform intermittent transmission. When the second conveyor belt assembly 33 performs intermittent transmission, it drives the first conveyor belt assembly 31 to perform intermittent transmission synchronously through the track mechanism 32. This arrangement facilitates the intermittent transmission of the spunlace nonwoven fabric, thereby making it easier to cut the spunlace nonwoven fabric.

[0032] When the spunlace nonwoven fabric enters the cutting blade 22, the second motor 210 is started. The second motor 210 drives the limiting rod 23 on the turntable 29 to perform a circular motion. When the limiting rod 23 performs a circular motion, it will drive the frame 24 to perform a vertical reciprocating motion along the surface of the slide rod 26. When the frame 24 performs a vertical reciprocating motion, it will drive the cutting blade 22 to perform a vertical reciprocating motion through the buffer rod 25. With the intermittent transmission of the spunlace nonwoven fabric, it is convenient to cut the nonwoven fabric. In addition, the spring 27 can alleviate the mechanical impact at the moment of cutting, avoid the hard contact of the cutting blade 22 and prevent wear, thus extending the service life of the cutting blade 22.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
