Description

Technical Field

[0001] This utility model relates to the technical field of automotive interior material processing, and in particular to a heat-cutting and sealing device for automotive sound-absorbing cotton. Background Technology

[0002] Cars are one of the most commonly used means of transportation for modern people. With the popularization of new energy vehicles, cars are gradually entering more and more families. During high-speed driving, the noise generated by tires and airflow is the main source of noise inside the car. In order to improve the riding experience and increase the comfort of the ride, various methods are usually used to isolate noise inside the car, such as adding sound-absorbing cotton to the door panels and sheet metal parts to absorb the noise generated by the vibration of external aluminum parts.

[0003] In the production process of automotive sound-absorbing cotton, hot-cutting edge sealing is a key processing step. Traditional hot-cutting edge sealing equipment completes the cutting through the cooperation of upper and lower molds. However, due to the characteristics of sound-absorbing cotton material, the waste material after hot pressing is easy to stick to the surface of the cutting tool or mold, making it difficult to clean and recycle the waste generated by hot cutting, resulting in reduced production efficiency and affecting the production and processing efficiency. Therefore, it needs to be improved. Utility Model Content

[0004] In order to facilitate the cleaning and recycling of waste generated by hot cutting and improve production and processing efficiency, this application provides a hot cutting and sealing device for automotive sound-absorbing cotton.

[0005] The technical solution of the heat-cutting and sealing equipment for automotive sound-absorbing cotton provided in this application is as follows: A heat-sealing device for automotive sound-absorbing cotton includes a conveyor frame, a conveyor belt, a support, a heat-cutting seat, a mold, and a heat-cutting knife. The conveyor belt is driven and mounted on the conveyor frame, the support is fixedly mounted on the conveyor frame, the heat-cutting seat is mounted on the support, the mold is raised and lowered on the heat-cutting seat, and the heat-cutting knife is located on the side of the mold facing the conveyor belt. The device also includes a bidirectional air pump. Several air vents are provided on the side of the mold facing the heat-cutting knife, and the air vents are interconnected with the air pump. The heat-cutting knife is located around the air vents. A mounting frame is also provided on the side wall of the conveyor frame, and a discharge air nozzle is provided on the mounting frame. The air outlet of the discharge air nozzle faces the surface of the conveyor belt.

[0006] By adopting the above technical solution, the sound-absorbing cotton is transported to the area directly below the hot-cutting seat via a conveyor belt. The mold is raised and lowered to bring the hot-cutting blade against the sound-absorbing cotton. After hot cutting, waste material is generated inside the hot-cutting blade. At this time, the bidirectional air pump works to draw air in through the vent, thereby creating negative pressure inside the hot-cutting blade. The waste material is then adsorbed at the vent. The mold is then raised to separate the waste material from the sound-absorbing cotton. Simultaneously, the conveyor belt continues to transport the hot-cut sound-absorbing cotton. Then, the bidirectional air pump works to blow air through the vent, blowing the waste material from between the hot-cutting blades onto the conveyor belt, thus separating the waste material from the hot-cutting blades. Finally, the waste material is blown to one side of the conveyor frame and collected through the discharge nozzle on the mounting frame, thus automatically separating and collecting the waste material. This method is convenient to operate and improves production efficiency.

[0007] Preferably, a filter screen is provided inside the air vent.

[0008] Preferably, the end wall of the filter screen is fixedly provided with a connecting ring, and the connecting ring is detachably connected to the inner wall of the air outlet by bolts.

[0009] By adopting the above technical solution, the filter screen can block impurities and dust, reduce the phenomenon of contamination of the bidirectional air pump, and help extend the service life of the bidirectional air pump. The connecting ring enables the disassembly of the filter screen, which is convenient for cleaning the filter screen for long-term use.

[0010] Preferably, the discharge nozzle is connected to a rotating shaft, and the discharge nozzle is rotatably connected to the mounting frame via the rotating shaft. The mounting frame is provided with a swing assembly for driving the rotating shaft to rotate.

[0011] Preferably, the rocking assembly includes a cylinder, a rack, and a gear. The gear is fixedly mounted on a rotating shaft and is coaxial with the rotating shaft. The cylinder is fixedly mounted on a mounting bracket. The rack is connected to the piston rod of the cylinder, and the rack and the gear mesh with each other.

[0012] By adopting the above technical solution, the waste material is blown off the air outlet by the bidirectional air pump and falls onto the conveyor belt. Then the feeding air nozzle works, and at the same time, the cylinder drives the rack to slide. The rack and gear collide, which in turn drives the rotating shaft to rotate, controlling the feeding air nozzle to swing back and forth. This can expand the blowing range of the feeding air nozzle and improve the recycling rate of waste material.

[0013] Preferably, the end of the conveyor frame away from the mounting frame is provided with a telescopic groove, a feeding plate is slidably disposed in the telescopic groove, and a sliding component for driving the feeding plate to slide is provided in the telescopic groove.

[0014] Preferably, the sliding component is a lead screw slide rail, which is fixedly installed on the inner wall of the expansion groove. The feeding plate is slidably connected to the lead screw slide rail, and the surface of the feeding plate is in contact with the inner wall of the expansion groove.

[0015] Preferably, the end wall of the feeding plate is integrally provided with a limiting plate, and a feeding trough for waste material to pass through is opened on the surface of the feeding plate and on one side of the limiting plate.

[0016] By adopting the above technical solution, the feeding plate is controlled to slide in the telescopic groove using a screw guide rail, and the distance between the limiting plate and the conveyor frame is controlled. The feeding nozzle blows the waste material from the conveyor belt onto the feeding plate. After the waste material slides on the feeding plate and hits the limiting plate, it falls into the feeding chute for recycling. The feeding plate can be precisely controlled by using a sliding component to drive the feeding plate, which can conveniently meet the recycling needs of different waste materials and improve the applicability of the equipment.

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a conveyor frame, conveyor belt, support, hot cutting seat, mold, hot cutting knife, bidirectional air pump, air vent, mounting frame, and unloading air nozzle, the mold lifts and lowers to drive the hot cutting knife to abut against the sound-absorbing cotton. After hot cutting, waste material is generated inside the hot cutting knife. At this time, the bidirectional air pump works to draw air into the air vent, thereby creating negative pressure inside the hot cutting knife. The waste material is attracted to the air vent. At this time, the mold is raised to separate the waste material from the sound-absorbing cotton. At the same time, the conveyor belt works to transport the hot-cut sound-absorbing cotton. Then, the bidirectional air pump works to blow air from the air vent, blowing the waste material from between the hot cutting knives onto the conveyor belt, thus separating the waste material from the hot cutting knife. Finally, the unloading air nozzle on the mounting frame works to blow the waste material to one side of the conveyor frame for recycling, thereby automatically separating and recycling the waste material. The operation is convenient and improves the production and processing efficiency. 2. By setting up a filter screen and connecting ring, when the bidirectional air pump is working and the air outlet is drawing in air, the filter screen can block impurities and dust, reducing the phenomenon of contamination of the bidirectional air pump and helping to extend the service life of the bidirectional air pump. The connecting ring allows the filter screen to be disassembled, making it easy to clean the filter screen for long-term use. 3. By setting up a rotating shaft, cylinder, rack and gear, after the waste material is blown down from the air outlet by the bidirectional air pump, the cylinder drives the rack to slide, and the rack and gear abut against each other, which in turn drives the rotating shaft to rotate, controlling the feeding air nozzle to swing back and forth. This can expand the blowing range of the feeding air nozzle and improve the recycling rate of waste material. Attached Figure Description

[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0023] This application discloses a heat-sealing device for automotive sound-absorbing cotton. (Refer to...) Figure 1 and Figure 2 It includes a conveyor frame 1, a conveyor belt 11, a support 2, a hot cutting seat 23, a mold 231, and a hot cutting blade 24. The conveyor belt 11 is driven and mounted on the conveyor frame 1, and the conveyor belt 11 is driven along the length of the conveyor frame 1. The conveyor frame 1 supports the conveyor belt 11. Several supports 23 are fixedly mounted on the conveyor frame 1. The hot cutting seat 23 is mounted on the support 2, and the mold 231 is raised and lowered inside the hot cutting seat 23. The hot cutting blade 24 is located on the side of the mold 231 facing the conveyor belt 11. The hot cutting blade 24 has a closed structure design. The sound-absorbing cotton is transported to the bottom of the hot cutting seat 23 by the conveyor belt 11. The hot cutting blade 24 is brought into contact with the sound-absorbing cotton by the raising and lowering of the mold 231. Waste material is generated inside the hot cutting blade 24 after hot cutting.

[0024] Reference Figures 1 to 3 The system also includes a bidirectional air pump 3. In this embodiment, the bidirectional air pump 3 is mounted on the mold 231. Several air vents 4 are provided on the side of the mold 231 facing the hot cutting blade 24. The air vents 4 are interconnected with the air pump, and the hot cutting blade 24 is located around the air vents 4. A mounting frame 5 is also fixedly mounted on the side wall of the conveyor frame 1. A discharge air nozzle 51 is provided on the mounting frame 5, and the air outlet 4 of the discharge air nozzle 51 is positioned facing the surface of the conveyor belt 11. After hot cutting, the mold 231 is raised slightly. At this time, the bidirectional air pump 3 works to draw air in through the air vent 4. The airflow enters between the hot cutting blades 24 through the gap between the hot cutting blades 24 and the conveyor belt 11, thereby creating a negative pressure inside the hot cutting blades 24. The waste material is adsorbed at the air vent 4. At this time, the mold 231 continues to be raised, which can separate the waste material from the sound-absorbing cotton. The conveyor belt 11 then works to transport the finished sound-absorbing cotton after hot cutting. After the finished sound-absorbing cotton is away from below the mold 231, the bidirectional air pump 3 works to blow air from the air vent 4, blowing the waste material from between the hot cutting blades 24 onto the conveyor belt 11, which can separate the waste material from the hot cutting blades 24. Finally, the unloading nozzle 51 on the mounting frame 5 works to blow the waste material to one side of the conveyor frame 1 for recycling, thereby automatically separating and recycling the waste material.

[0025] Reference Figure 3 A filter screen 41 is installed inside the air outlet 4. A connecting ring 42 is fixedly installed on the end wall of the filter screen 41. The connecting ring 42 is detachably connected to the inner wall of the air outlet 4 by bolts. The filter screen 41 can block impurities and dust, reduce the contamination of the bidirectional air pump 3, and help extend the service life of the bidirectional air pump 3. The connecting ring 42 allows the filter screen 41 to be disassembled, which is convenient for cleaning the filter screen 41 for long-term use.

[0026] Reference Figure 1 The discharge nozzle 51 is connected to a rotating shaft 6, and the discharge nozzle 51 is rotatably connected to the mounting frame 5 via the rotating shaft 6. The mounting frame 5 is equipped with a swing assembly for driving the rotating shaft 6 to rotate. The swing assembly includes a cylinder 71, a rack 72, and a gear 73. The gear 73 is fixedly mounted on the rotating shaft 6 and is coaxial with the rotating shaft 6. The rack 72 is connected to the piston rod of the cylinder 71, and the rack 72 and the gear 73 mesh with each other. After the waste material is blown off from the air outlet 4 by the bidirectional air pump 3 and falls onto the conveyor belt 11, the discharge nozzle 51 operates. At the same time, the cylinder 71 drives the rack 72 to slide, and the rack 72 abuts against the gear 73, thereby driving the rotating shaft 6 to rotate and controlling the discharge nozzle 51 to swing back and forth. This can expand the blowing range of the discharge nozzle 51 and improve the waste recovery rate.

[0027] Reference Figure 2 A telescopic groove 8 is provided at one end of the conveyor frame 1 away from the mounting frame 5. The length of the telescopic groove 8 is set along the width of the conveyor frame 1. A feed plate 81 is slidably disposed in the telescopic groove 8. A sliding component for driving the feed plate 81 to slide is provided in the telescopic groove 8. The sliding component is a lead screw slide rail 9, which is fixedly disposed on the inner wall of the telescopic groove 8. The feed plate 81 is slidably connected to the lead screw slide rail 9, and the surface of the feed plate 81 is in contact with the inner wall of the telescopic groove 8. A limit plate 811 is integrally provided on the end wall of the feed plate 81. The length of the limit plate 81 is set along the length of the feed plate 81. A feed trough 812 for waste material to pass through is provided on the surface of the feed plate 81 and on one side of the limit plate 811. The feed plate 81 is controlled to slide within the telescopic groove 8 by the lead screw slide rail 9, controlling the distance between the limit plate 811 and the conveyor frame 1. The feed nozzle 51 blows the waste material from the conveyor belt 11 onto the feed plate 81. After sliding on the feed plate 81 and hitting the limit plate 811, the waste material falls through the feed chute 812 for recycling. The feed plate 81 is driven to slide by the sliding component, which can accurately control the feed position of the waste material, making it convenient to meet the recycling needs of different waste materials and improving the applicability of the equipment.

[0028] The implementation principle of the automotive sound-absorbing cotton hot-cutting and sealing device in this application embodiment is as follows: The sound-absorbing cotton is transported to the area directly below the hot-cutting seat 23 via the conveyor belt 11. The conveyor belt 11 stops working. At this time, the mold 231 is raised and lowered to drive the hot-cutting blade 24 to abut against the sound-absorbing cotton. After hot cutting, waste material will be generated inside the hot-cutting blade 24. After hot cutting, the mold 231 is raised a little distance, and the bidirectional air pump 3 works to make the air vent 4 draw in air. The airflow enters the space between the hot-cutting blade 24 and the conveyor belt 11, thereby generating negative pressure inside the hot-cutting blade 24. The waste material will be adsorbed at the air vent 4. At this time, the mold 231 continues to be raised, which can separate the waste material from the sound-absorbing cotton.

[0029] Then, the conveyor belt 11 works to transport the finished sound-absorbing cotton after hot cutting. After the finished sound-absorbing cotton is away from the bottom of the mold 231, the bidirectional air pump 3 works to blow air from the air outlet 4, which blows the waste material from between the hot cutting blades 24 onto the conveyor belt 11. This can separate the waste material from the hot cutting blades 24. Finally, the discharge air nozzle 51 on the mounting frame 5 works to blow the waste material to one side of the conveyor frame 1 and drop it for recycling. This automatically separates and recycles the waste material, making the operation convenient and quick, while also achieving low cost and improving production and processing efficiency.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
