Description

Technical Field

[0001] This utility model relates to the field of texturing machine shredding technology, specifically, to a pneumatic shredding device for a texturing machine. Background Technology

[0002] The texturing machine's filament cutting device is used during the texturing process to promptly cut off problematic filaments if they exhibit abnormalities such as breakage, excessive twisting, or insufficient twisting that seriously affect product quality. For example, if filaments become overstretched or twisted during twisting due to jamming of a guide component, the filament cutting mechanism will quickly intervene to prevent defective filaments from entering the next process, thus avoiding any impact on the quality of the entire batch of products.

[0003] Current slicing devices tend to leave thread ends or dust inside after cutting the thread. Over time, this can affect the cutting effect of the internal blades and impact the operation of the device. It requires frequent cleaning, and the usual cleaning method is manual cleaning, which is inefficient, or a separate blowing structure can be set up to blow the dust out.

[0004] However, the above methods require the addition of an electric drive structure, which increases the energy consumption of the equipment. At the same time, due to the limited internal cutting space, the blowing can easily create dead corners, which will still cause some dust to accumulate and not be discharged, resulting in poor cleaning effect. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a pneumatic shredding device for a texturing machine to solve the problems in the background art.

[0006] To solve the above problems, the present invention adopts the following technical solution;

[0007] A pneumatic slicing device for a texturing machine includes a vertical tube with a square outer cover fixedly connected to its outer side. The interior of the square outer cover communicates with the interior of the vertical tube. A narrow inlet channel is provided in the upper half of the vertical tube, and a wide outlet channel communicating with the square outer cover is provided in the lower half of the vertical tube. Two cutting rollers are rotatably connected inside the square outer cover, with one end of the back of each of the two cutting rollers extending to the outside of the square outer cover. A drive mechanism is installed on the back of the square outer cover, and the drive mechanism is connected and cooperates with the back ends of the two cutting rollers. A blower mechanism is installed on both sides of the square outer cover, and a transmission component is fixedly connected to both sides of the square outer cover. The drive mechanism drives the blower mechanism via the transmission component.

[0008] The drive mechanism includes a servo motor, a first gear, and two second gears. The servo motor is fixedly mounted on the back of the square cover. The output end of the servo motor is fixedly connected to the first gear through a coupling. The two second gears are respectively fixedly mounted on one end of the back of the two cutting rollers. The outer side of the first gear meshes with the outer side of the two second gears.

[0009] The transmission component includes two positioning sleeves, a rotating rod, two first bevel gears, and two second bevel gears. The two positioning sleeves are fixedly installed on the outside of the square outer cover. The outside of the rotating rod is rotatably connected between the inside of the two positioning sleeves. The two first bevel gears are respectively fixedly connected to the two ends of the two rotating rods. The two second bevel gears are respectively fixedly installed on the blower mechanism and one side of the second bevel gear. The outside of the two second bevel gears meshes with the outside of the two first bevel gears.

[0010] The blower mechanism includes a transmission rod, a fan blade, and a protective cover. One end of the transmission rod is fixedly connected to a second bevel gear located on the front. The other end of the transmission rod passes through the interior of the protective cover and is rotatably connected thereto. The end of the transmission rod located inside the protective cover is fixedly connected to the fan blade. The protective cover is fixedly installed on the outside of the square outer cover.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] Please see Figures 1-4 In this utility model, a pneumatic slicing device for a texturing machine includes a vertical tube 1. A square outer cover 2 is fixedly connected to the outside of the vertical tube 1. The inside of the square outer cover 2 is connected to the inside of the vertical tube 1. A narrow inlet channel 3 is opened in the upper half of the vertical tube 1, and a wide outlet channel 4 is opened in the lower half of the vertical tube 1, which is connected to the square outer cover 2. Two cutting rollers 5 are rotatably connected inside the square outer cover 2. One end of the back of each of the two cutting rollers 5 extends to the outside of the square outer cover 2. A drive mechanism 6 is installed on the back of the square outer cover 2. The drive mechanism 6 is connected and cooperates with the back ends of the two cutting rollers 5. A blower mechanism 7 is installed on both sides of the square outer cover 2. A transmission component 8 is fixedly connected to both sides of the square outer cover 2. The drive mechanism 6 drives the blower mechanism 7 through the transmission component 8.

[0023] In this invention, the vertical tube 1 serves as the main body of the device. The thread enters from the top of the vertical tube 1 through a narrow inlet channel 3, passes between two cutting rollers 5, and then exits along a wide outlet channel 4, achieving normal thread feeding. When cutting is required, the drive mechanism 6 is activated to rotate the two cutting rollers 5 relative to each other, cutting the thread in the middle. Simultaneously, the drive mechanism 6 drives the cutting rollers 5 to rotate and cut, while the transmission component 8 drives two blower mechanisms 7 to blow air inwards from both sides of the square outer casing 2. After the high-speed airflow enters the interior of the vertical tube 1, the difference in inner diameter between the narrow inlet channel 3 and the wide outlet channel 4 causes the airflow pressure to blow downwards, expelling residual thread and dust through the wide outlet channel 4. This achieves the advantages of good cleaning effect, avoiding dead corner residue, and energy saving without the need for an additional electric drive structure. It solves the problems of existing technologies that require an independent electric drive structure, increasing equipment energy consumption, and where limited internal cutting space can easily create dead corners, leading to some thread dust accumulation and poor cleaning effect.

[0024] Please see Figure 2 and Figure 3 The drive mechanism 6 includes a servo motor 61, a first gear 62 and two second gears 63. The servo motor 61 is fixedly installed on the back of the square outer cover 2. The output end of the servo motor 61 is fixedly connected to the first gear 62 through a coupling. The two second gears 63 are respectively fixedly installed on one end of the back of the two cutting rollers 5. The outer side of the first gear 62 meshes with the outer side of the two second gears 63.

[0025] In this invention, the servo motor 61 is started to drive the first gear 62 to rotate, which in turn drives the two second gears 63 to rotate, which in turn drives the two cutting rollers 5 to rotate relative to each other, and cuts the wire downwards.

[0026] Please see Figure 2 and Figure 3 The transmission component 8 includes two positioning sleeves 81, a rotating rod 82, two first bevel gears 83, and two second bevel gears 84. The two positioning sleeves 81 are fixedly installed on the outside of the square outer cover 2. The outside of the rotating rod 82 is rotatably connected to the inside of the two positioning sleeves 81. The two first bevel gears 83 are respectively fixedly connected to the two ends of the two rotating rods 82. The two second bevel gears 84 are respectively fixedly installed on the blower mechanism 7 and on one side of the second bevel gear 84. The outside of the two second bevel gears 84 meshes with the outside of the two first bevel gears 83.

[0027] In this invention, two second gears 63 drive two left and right second bevel gears 84 to rotate, which in turn drive the rotating rod 82 to rotate the first bevel gear 83 at its other end and the second bevel gear 84 connected to the blower mechanism 7. This drives the blower mechanism 7 to blow the inside of the square outer cover 2, so that the lint and dust inside are discharged directly downward along the wide outlet channel 4, improving the blowing effect and effectively avoiding dead corner residue.

[0028] Please see Figure 1 and Figure 2 The blower mechanism 7 includes a transmission rod 71, a fan blade 72, and a protective cover 73. One end of the transmission rod 71 is fixedly connected to the second bevel gear 84 located on the front. The other end of the transmission rod 71 passes through the interior of the protective cover 73 and is rotatably connected to it. The end of the transmission rod 71 located inside the protective cover 73 is fixedly connected to the fan blade 72. The protective cover 73 is fixedly installed on the outside of the square outer cover 2.

[0029] In this invention, the second bevel gear 84 drives the transmission rod 71 to rotate, thereby driving the fan blade 72 to rotate and blow into the inside of the square outer cover 2. The high-speed airflow enters the inside of the vertical tube 1 and is discharged along the wide outlet channel 4 at the bottom to blow away the thread ends and dust.

[0030] Please see Figure 1Among them, the two protective covers 73 are provided with air inlets 731 on the side away from the square outer cover 2, and the air inlets 731 are provided with dustproof nets 732 inside.

[0031] In this invention, air is drawn in through the air inlet 731 and enters the interior of the protective cover 73, and dustproof net 732 is used for dust protection to prevent foreign objects from entering.

[0032] Please see Figure 1 Among them, the outer side of the cutting roller 5 is fixedly connected with correspondingly distributed cutters 51 and auxiliary blocks 52 in an annular shape.

[0033] In this invention, dynamic cutting is achieved by rotating and cooperating the cutter 51 and auxiliary block 52 on the outer side of the two cutting rollers 5. After cutting, the cutter 51 and auxiliary block 52 rotate at a certain angle to separate, maintaining the space for the thread to pass through smoothly.

[0034] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
