Description

Technical Field

[0001] The utility model relates to the technical field of nanofiber sound-absorbing cotton production, and specifically relates to a production and forming device for nanofiber sound-absorbing cotton. Background Technique

[0002] Nanofiber sound-absorbing cotton is a new type of sound-absorbing material. Its core function is to absorb sound waves and convert sound energy into heat energy, thereby achieving the effect of reducing sound transmission. This material is usually formed by stacking and hot-pressing polyester fibers, and has the characteristics of non-toxic, harmless, and pollution-free. The production process of sound-absorbing cotton generally includes laying materials, carding, web-forming, and drying and forming, etc. The processing equipment used for drying and forming is the most common, so a production and forming device is required.

[0003] In the prior art, the patent application number "CN202322101951.5" is disclosed, which is a forming device for producing automotive sound-absorbing cotton. It includes two support frames. One side of the two support frames close to each other is rotatably connected with a rotating shaft. The outer surfaces of the two rotating shafts are jointly driven and connected with a conveyor belt. By setting the support frames, the rotating shaft, the rotating motor, and the conveyor belt, the transportation and transfer of the sound-absorbing cotton can be realized, and the forming efficiency of the sound-absorbing cotton can be further improved. The rotating motor drives the rotating shaft and the conveyor belt to work under the support and cooperation of the support frame, so that the sound-absorbing cotton is transported.

An array of through holes 10 are formed inside the conveyor belt 9. Through the setting of the through holes 10, the heat can be transmitted upward through the through holes 10 to dry the sound-absorbing cotton.

[0030] On the upper sides of both limiting plates 12, there are two fastening bolts 14 threadedly connected for fixing the limiting plates 12. Through the setting of the limiting plates 12, the positions of the two positioning clamping plates 11 can be utilized, and the use of the fastening bolts 14 can be combined to fix the entire clamping plate 11, enabling the fan 13 to rotate stably and blow air to convey heat upward, facilitating the drying and forming process. The right side of the rotating roller 8 penetrates through the fixed cross plate 2 and extends to the right side of the fixed cross plate 2. The right side of the rotating roller 8 is fixedly connected to a second servo motor 18 through a motor mounting plate.

[0031] On the inner side surface of the top cover 3, there is a fixed plate 31 installed. The lower side of the fixed plate 31 is slidably connected to a pressing plate 28. Inside the pressing plate 28, heating rods 30 are arrayedly connected. Through the setting of the pressing plate 28, the heat generated by the heating rods 30 can make the pressing plate 28 uniformly heated. At the same time, the pressing plate 28 can also move to the upper position of the conveyor belt 9 to heat the sound-absorbing cotton by baking, so as to produce the sound-absorbing cotton flexibly and conveniently. The upper side of the pressing plate 28 penetrates through the fixed plate 31 and extends to the upper side of the top cover 3. Between the pressing plate 28 and the fixed plate 31, springs 29 are installed in an array. On the upper side of the top cover 3, a vertical plate 26 is fixedly connected.

[0032] Both ends of the U-shaped connecting plate 4 are fixedly connected to U-shaped side plates 19. On the inner side surfaces of the two U-shaped side plates 19, sealing rotary plates 20 are rotatably connected. On one side of each of the two sealing rotary plates 20, a rubber strip 21 is connected. On the upper side of the production and forming equipment main body 1, two symmetrically distributed sealing plug plates 22 are clamped. On one side of each of the two sealing plug plates 22, a sliding plate 23 is installed. Through the setting of the sliding plate 23, the sliding plate 23 can temporarily receive the sound-absorbing cotton after forming and conveying, which is convenient to use. On both ends of the top cover 3, sealing glass windows 25 are fixedly installed.

[0033] The rear side of the double-headed lead screw 5 penetrates through the U-shaped connecting plate 4 and extends to the rear side of the U-shaped connecting plate 4. A first servo motor 17 is fixedly connected to the rear side of the double-headed lead screw 5 through a motor mounting plate. By the forward and reverse rotation of the first servo motor 17, the first threaded block 6 and the second threaded block 15 on the double-headed lead screw 5 can be adjusted to move back and forth, which is used to evenly dry and heat the sound-absorbing cotton and improve the forming efficiency. Two connecting slide bars 16 are connected to the inner side surface of the U-shaped connecting plate 4. The two connecting slide bars 16 are slidably connected to the first threaded block 6 and the second threaded block 15. Through the arrangement of the connecting slide bars 16, the movement trajectories of the two threaded blocks can be restricted by the two connecting slide bars 16, so that the two threaded blocks can move and adjust smoothly, which is convenient to use. Two support feet 24 are respectively fixedly connected to the lower side of the production and forming equipment main body 1.

[0034] Two installation grooves 111 are opened on the lower side of the production and forming equipment main body 1. The installation grooves 111 are adapted to the rubber strips 21. One side of the rubber strip 21 is snap-connected to the lower side of the production and forming equipment main body 1 through the installation grooves 111.

[0035] The working principle of a nano-fiber sound-absorbing cotton production and forming equipment provided by the utility model is as follows:

[0036] By starting the first servo motor 17, the output shaft of the first servo motor 17 drives the double-headed lead screw 5 to rotate, so that the first threaded block 6 and the second threaded block 15 on the double-headed lead screw 5 can move towards each other. Then, two hot air blowers 7 on the two threads are turned on, and the hot air blowers 7 blow hot air upwards to dry and heat the nano-fiber sound-absorbing cotton conveyed on the conveyor belt 9. Then, the fan 13 is turned on, so that the fan 13 can quickly transfer the heat upwards, so as to quickly dry the bottom of the nano-fiber sound-absorbing cotton through the through holes 10 on the conveyor belt 9. In this way, the nano-fiber sound-absorbing cotton can be evenly dried and conveyed, ensuring the forming quality of the sound-absorbing cotton and improving the production efficiency of the nano-fiber sound-absorbing cotton production and forming equipment;

[0037] By energizing multiple heating rods 30 to generate heat, and then driving the cam rod 27 to slowly rotate by the output shaft of the third servo motor 32. At this time, the cam rod 27 can squeeze the support plate 33, so that the pressing plate 28 equipped with the spring 29 can move downward. At this time, the pressing plate 28 at a certain temperature can thermally press the sound-absorbing cotton on the conveyor belt 9 to further dry the sound-absorbing cotton and accelerate the forming speed of the sound-absorbing cotton. At the same time, when the top of the cam rod 27 does not squeeze the support plate 33, the elastic pressing plate 28 will complete the reset to facilitate the next thermoforming. Then, rotate the two sealing rotary plates 20 upward respectively, so that the rubber strips 21 at the sealing rotary plates 20 can be clamped into the installation groove 111 below the main body 1 of the production forming equipment to seal the U-shaped connecting plate 4. Coupled with the use of the two sealing plug plates 22, it can be used to seal the rollers 8 and the conveyor belt 9 at the two fixed cross plates 2, avoiding the dissipation of heat inside the production forming equipment and enabling the drying and forming work to continue.

[0038] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
