Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically a cutting equipment for a seat belt production line. Background Technology

[0002] Safety belts are safety components used on equipment. They are belts used to ensure safety when riding in vehicles such as airplanes or cars, or when working at heights or performing skills. The main raw materials of safety belts are polyester, polypropylene, and nylon. In the safety belt production line, cutting equipment is used to cut the woven safety belts into the required lengths.

[0003] Current seat belts are made by weaving, and the cut edges tend to loosen after cutting, resulting in uneven cuts that are not conducive to subsequent use. To address this, we propose a cutting device for seat belt production lines. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting equipment for a seat belt production line, which can make the cut edge of the seat belt more even and prevent it from becoming loose after cutting, thereby improving the cutting quality and facilitating the subsequent use of the seat belt. It solves the problem that the cut edge of the current seat belt is easy to become loose after cutting because the seat belt is woven, resulting in an uneven cut edge that is not conducive to subsequent use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for a seat belt production line, comprising a fixed base and a fixed frame. A cylinder is fixedly installed on the upper surface of the fixed base, and a hot cutting blade is fixedly connected to the output end of the cylinder. The hot cutting blade is located inside the fixed frame. A through-hole is provided on the outer surface of the fixed frame near the lower surface. Through holes are symmetrically provided on both sides above the through-hole on the outer surface of the fixed frame. Sliding rods are slidably installed inside the two through holes. A translation scraper is fixedly connected to one end of each sliding rod inside the fixed frame. A second helical spring is spirally wound on the outer surface of each sliding rod, and the second helical spring is located inside the fixed frame.

[0006] Preferably, both of the two translation scrapers have inclined surfaces on their inner sides, and the inclined surfaces make the distance between the two translation scrapers decrease from top to bottom, so that the hot cutting knife can be inserted between the two translation scrapers when it descends.

[0007] Preferably, the lower surface of the fixed base is provided with fixing holes near the four corners, and the fixed base is fixed to the safety belt production line after the bolts pass through the fixing holes.

[0008] Preferably, the upper surface of the fixed base is provided with a groove located below the hot cutting blade, a rotating roller is rotatably installed inside the fixed base, a rotating motor is fixedly installed on the front surface of the fixed base, and the end of the output shaft of the rotating motor is fixedly connected to the end of the rotating roller.

[0009] Preferably, a rotating scraper is rotatably installed inside the fixed base near the rotating roller. A first helical spring is fixedly connected to the outer surface of the rotating scraper, and the end of the first helical spring is fixedly connected to the inner wall of the fixed base. The rotating motor drives the rotating roller to rotate, and the elastic force of the first helical spring causes the rotating scraper to rotate and contact the outer surface of the rotating roller, thereby scraping off the adhering material on the outer surface of the rotating roller.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model, by setting up a fixed frame, cylinder, hot cutting blade, slide bar, second helical spring, translation scraper, and through hole, achieves a smoother cut after the seat belt is cut, preventing loosening and improving cutting quality, thus facilitating the subsequent use of the seat belt. The fixed base is fixed on the seat belt production line. During the cutting process, the seat belt passes through the fixed frame via the through hole. The cylinder drives the hot cutting blade to descend and complete the cutting of the seat belt. At the same time, the hot cutting blade melts the cut of the seat belt. After cooling, the melted material fixes the cut to prevent it from loosening. After the cutting is completed, the cylinder drives the hot cutting blade to rise and reset. The elastic force of the second helical spring acts on the translation scraper, which scrapes off the melted material adhering to the outer surface of the hot cutting blade.

[0012] 2. By setting an inclined surface, the distance between the two translation scrapers decreases from top to bottom, so that the hot cutting blade can be inserted between the two translation scrapers when it descends.

[0013] 3. This utility model achieves the effect of easily removing the dripping molten material generated during the hot cutting of the seat belt by setting up a rotating roller, a rotating motor, a rotating scraper, a groove and a first helical spring. When the seat belt is cut by the hot cutting knife, a small amount of molten material drips onto the outer surface of the rotating roller. The rotating motor drives the rotating roller to rotate, and the elastic force of the first helical spring causes the rotating scraper to rotate and contact the outer surface of the rotating roller. The rotating scraper removes the adhering material from the outer surface of the rotating roller. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figures 1-4 As shown, this utility model proposes a cutting device for a seat belt production line, including a fixed base 2 and a fixed frame 4. A cylinder 5 is fixedly installed on the upper surface of the fixed base 2, and a hot cutting blade 9 is fixedly connected to the output end of the cylinder 5. The hot cutting blade 9 is located inside the fixed frame 4. The cylinder 5 drives the hot cutting blade 9 to rise and fall to complete the cutting of the seat belt on the production line. A through-hole 3 is provided on the outer surface of the fixed frame 4 near the lower surface. The seat belt passes through the through-hole 3 through the fixed frame 4. Through holes 8 are symmetrically provided on both sides above the through-hole 3 on the outer surface of the fixed frame 4. Sliding rods 7 are slidably installed inside the two through holes 8. The two sliding rods 7 are located inside the fixed frame 4. Each end is fixedly connected with a translation scraper 15. The outer surface of each of the two slide rods 7 is spirally wound with a second helical spring 14, and the second helical spring 14 is located inside the fixed frame 4. The inner side of each of the two translation scrapers 15 is provided with an inclined surface 16. The inclined surface 16 makes the distance between the two translation scrapers 15 decrease from top to bottom, so that the hot cutting knife 9 can be inserted between the two translation scrapers 15 when it descends. When the hot cutting knife 9 cuts the safety belt, the two translation scrapers 15 are clamped on both sides of the hot cutting knife 9. The lower surface of the fixed base 2 is provided with a fixing hole 1 near the four corners. After the bolt passes through the fixing hole 1, the fixed base 2 is fixed to the safety belt production line.

[0022] In use, the fixed base 2 is fixed on the seat belt production line. When the seat belt is cut, it passes through the through-hole 3 and the fixed frame 4. The cylinder 5 drives the hot cutting blade 9 to descend and complete the cutting of the seat belt. At the same time, the hot cutting blade 9 heats and melts the cut of the seat belt. After the melt cools, it fixes the cut to prevent the cut from loosening, making the cut smoother and improving the cutting quality. After the cutting is completed, the cylinder 5 drives the hot cutting blade 9 to rise and reset. The elastic force of the second helical spring 14 acts on the translation scraper 15, which scrapes off the melt adhering to the outer surface of the hot cutting blade 9.

[0024] like Figures 1-3 As shown, the present invention proposes a cutting device for a seat belt production line. Compared with Embodiment 1, this embodiment further includes a slot 10 provided on the upper surface of the fixed base 2 below the hot cutting blade 9. A rotating roller 13 is rotatably installed inside the fixed base 2. A rotating motor 6 is fixedly installed on the front surface of the fixed base 2. The end of the output shaft of the rotating motor 6 is fixedly connected to the end of the rotating roller 13. A rotating scraper 12 is rotatably installed inside the fixed base 2 near the rotating roller 13. A first helical spring 11 is fixedly connected to the outer surface of the rotating scraper 12, and the end of the first helical spring 11 is fixedly connected to the inner wall of the fixed base 2. The elastic force of the first helical spring 11 causes the rotating scraper 12 to contact the outer surface of the rotating roller 13.

[0025] In this embodiment, when the seat belt is cut by the hot cutter 9, a small amount of molten material drips onto the outer surface of the rotating roller 13. The rotating motor 6 drives the rotating roller 13 to rotate, and the elastic force of the first helical spring 11 causes the rotating scraper 12 to rotate and contact the outer surface of the rotating roller 13. The rotating scraper 12 scrapes off the adhering material on the outer surface of the rotating roller 13.
