The outer circumference of the annular elastic bladder is provided with uniformly distributed air holes.
[0013] Based on the aforementioned scheme: the opening mechanism includes a cylinder and a roller adapted to the cylinder. An opening motor is fixed to one side of the outer wall of the opening device by screws. One end of the outer wall of the cylinder is rotatably connected to the output end of the opening motor by a coupling. The top of the opening device has an arc-shaped structure, and the inner wall of the top of the opening device is fitted with evenly distributed elastic columns by screws. Each elastic column is provided with a brush head adapted to the roller near the roller end.
[0014] Based on the aforementioned scheme, the preferred embodiment is as follows: the outer circumference of the elastic column is provided with uniformly distributed annular grooves, the interior of the elastic column is a hollow structure, and an oscillating spring is provided between the inner wall of one end of the elastic column and the inner wall of one side of the opening device.
[0015] A further preferred embodiment based on the aforementioned scheme is that the outer wall of the feeding conveyor belt is integrally provided with equally spaced strip-shaped protrusions.

A lifting seat is welded to the bottom of each lifting spring. The lifting seat slides between the inner walls of both sides of the winding frame. The winding drum is detachably and rotatably inserted into the inner wall of the lifting seat through the winding rods.
[0018] The beneficial effects of this invention are as follows:
[0019] 1. By setting up a first rubber rod and a first annular plate, the present invention can utilize the operation of a mixing motor to drive the rotating main shaft to rotate, thereby driving the first rubber rod to achieve stirring and mixing. The first annular plate plays a role in gathering materials, thereby improving the mixing effect and ensuring product quality.
[0020] 2. By setting up a support frame and impeller, rotation can be achieved based on the wind force of the wind conveying channel, which scrapes and assists in conveying the material attached to the edge of the secondary mixing chamber, improving reliability and practicality; by setting up a second rubber rod and a second annular plate, after the material is initially mixed by the first rubber rod, the material can be mixed a second time by the second rubber rod, further improving the degree of mixing and ensuring product quality.
[0021] 3. By setting up a spherical motor chamber, reliable support is provided for the mixing motor, while minimizing interference with the feed and ensuring the airflow entering the secondary mixing chamber through the pneumatic conveying channel, thus improving reliability. By setting up an unloading hole, the unloading effect is achieved, ensuring airflow transmission efficiency while preventing excessive local airflow from causing materials to be blown out in the opposite direction, further improving reliability.
[0022] 4. By setting the first and second rubber rods with hollow structures, the deformation capacity of the first and second rubber rods can be improved, and the product can be damaged due to excessive local tearing force by deformation. The annular protrusion can improve the mixing and stirring effect and prevent cotton lint from sliding along the central axis of the first and second rubber rods, thus improving practicality.
[0023] 5. By setting up structures such as planar spiral springs, annular elastic bladders, and locking posts, the planar spiral springs can store energy when the main shaft rotates. When the planar spiral springs store enough energy, the annular elastic bladder deforms to cause the locking posts to disengage from the slots in the secondary mixing chamber, causing the annular elastic bladder to rotate rapidly. During the deformation and rotation of the annular elastic bladder, a large amount of airflow is generated near the annular elastic bladder and its vents, thereby shaking off the cotton fibers adhering to the inner wall of the secondary mixing chamber and the surface of the annular elastic bladder, avoiding material residue and improving the reliability of material mixing.
[0024] 6. By setting up elastic posts and brush heads, the rotation of the rollers during cylinder and roller operation allows the rollers to come into contact with the brush head, thereby brushing off the lint adhering to the roller surface, improving practicality.
[0025] 7. By setting an annular groove and an oscillating spring, when the roller contacts the brush head, the elastic column is deformed under the force applied by the roller. As the roller rotates continuously, the elastic column intermittently contacts and separates from the roller, so that the elastic column oscillates through the annular groove and the oscillating spring, thereby shaking off the cotton fibers attached to the surface of the elastic column and the brush head, further improving practicality.
[0026] 8. By setting up strip-shaped protrusions, the passing cotton fibers can be carried, allowing finer impurities to fall into the gaps between the protrusions, thus achieving the purpose of screening and further ensuring product quality.
[0027] 9. By setting up structures such as hot press rollers and cold press rollers, the combed insulation cotton can be subjected to hot pressing, cold pressing, fan cooling, cutting and winding processes in sequence to obtain the target product. The whole process is orderly and reliable.
[0028] 10. By setting up structures such as a take-up roller and lifting springs, the insulation cotton can make closer contact with the take-up roller based on the pressure of the lifting springs. This allows the take-up roller to rotate as the insulation cotton is rolled up, eliminating the need for continuous manual pressing and saving manpower.
[0029] 11. This invention utilizes automotive interior trim and scraps from automotive interior trim production to produce thermal insulation cotton that has excellent fire resistance, high loft, good thermal insulation effect, and long service life.
[0030] 12. The thermal insulation cotton produced by this invention is made from automotive interior trim and scrap materials, resulting in low production costs, strong environmental friendliness, and a certain degree of water resistance, thus better meeting the needs of agricultural greenhouses.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances. Example
[0045] A device for producing thermal insulation cotton from automotive waste, such as Figure 1-9 As shown, the system includes an opening device 1, a mixing chamber 2, a pneumatic conveying channel 3, a secondary mixing chamber 4, a baking chamber 5, a carding machine 6, and a conveying platform 33. The output ends of the opening device 1 are all connected to the interior of the mixing chamber 2. The mixing chamber 2 is connected to the interior of the secondary mixing chamber 4 via the pneumatic conveying channel 3. The output end of the secondary mixing chamber 4 is connected to the input end of the baking chamber 5, and the output end of the baking chamber 5 is connected to the feed end of the carding machine 6. The conveying platform 33 is located at the discharge end of the carding machine 6. The opening device 1 is equipped with a feeding conveyor belt 9 for feeding materials. A mixing hopper 7 is welded to the outer wall of the secondary mixing chamber 4 near the pneumatic conveying channel 3. A mixing mechanism is installed inside the secondary mixing chamber 4, and an opening mechanism is installed inside the opening device 1. The mixing mechanism includes a mixing motor 28 and a rotating main shaft 27. A motor chamber 21 for supporting the mixing motor 28 is fixed to the top inner wall of the mixing hopper 7 by a mounting rod. One side of the outer wall of the mixing motor 28 is fixed to one side of the inner wall of the motor chamber 21 by screws. The rotating main shaft 27 is rotatably connected to the output end of the mixing motor 28 via a coupling. The outer circumference of the rotating main shaft 27 is provided with evenly distributed first rubber rods 18. A first annular plate 22 is provided on the outer side of the first rubber rods 18 and welded to the inner circumference of the secondary mixing chamber 4. The first annular plate 22 has a bucket-shaped structure. In use, the user feeds material through the feeding conveyor belt 9 on each opening device 1. After being opened by the opening mechanism in the opening device 1, the material is sent into the mixing chamber 2 for primary mixing. Under the action of wind, the material passes through the mixing chamber 2 and reaches the wind conveying channel 3, which then transports the material from the mixing hopper 7 to the secondary mixing chamber 4. By setting the first rubber rods 18 and the first annular plate 22, the mixing motor 28 can drive the rotating main shaft 27 to rotate, thereby driving the first rubber rods 18 to achieve stirring and mixing. The first annular plate 22 serves to gather the material, thus improving the mixing effect and ensuring product quality.
[0046] To improve the blending effect; such as Figure 4-6As shown, the secondary mixing chamber 4 is equipped with evenly distributed support frames 20 on the inner circumference of the mixing hopper 7, and a rotatable impeller 19 is installed on the support frame 20. By setting the support frame 20 and the impeller 19, rotation can be achieved based on the wind force in the wind conveying channel 3, which scrapes and assists in conveying the material attached to the edge of the secondary mixing chamber 4, thereby improving reliability and practicality.
[0047] To further enhance the blending effect; such as Figure 5 , Figure 6 As shown, a second rubber rod 24 with uniform circumferential distribution is provided on the outer wall of one end of the rotating main shaft 27. A second annular plate 25 is provided on the outer side of the second rubber rod 24. The second annular plate 25 is welded to the inner circumferential wall of the secondary mixing chamber 4. The second annular plate 25 has a bucket-shaped structure. The inner diameter of the second annular plate 25 is smaller than the inner diameter of the first annular plate 22, and the number of second rubber rods 24 is greater than the number of first rubber rods 18. By setting the second rubber rods 24 and the second annular plate 25, the material can be initially mixed by the first rubber rods 18, and then the material can be mixed a second time by the second rubber rods 24, which further improves the degree of mixing and ensures product quality.
[0048] To improve conveying efficiency; such as Figure 1 , Figure 2 As shown, the motor chamber 21 is a spherical structure with an opening on one side. By setting the motor chamber 21 with a spherical structure, reliable support is provided for the mixing motor 28, while minimizing interference with the feeding process and ensuring the airflow input into the secondary mixing chamber 4 through the pneumatic conveying channel 3, thereby improving reliability.
[0049] To facilitate unloading; such as Figure 5 , Figure 6 As shown, both the outer wall of the first annular plate 22 and the outer wall of the second annular plate 25 are provided with circumferentially distributed discharge holes 31. By setting the discharge holes 31, the discharge effect can be achieved, ensuring the airflow transmission efficiency while avoiding excessive local airflow that could cause the material to be blown out in the opposite direction, thus further improving reliability.
[0050] To avoid damaging the product; such as Figure 6 As shown, both the first rubber rod 18 and the second rubber rod 24 are hollow structures, and the outer circumferential walls of both the first rubber rod 18 and the second rubber rod 24 are integrally provided with equidistantly distributed annular protrusions 29. By setting the first rubber rod 18 and the second rubber rod 24 with hollow structures, the deformation capacity of the first rubber rod 18 and the second rubber rod 24 can be improved, and the phenomenon of product damage due to excessive local tearing force can be avoided by deformation. The annular protrusions 29 can improve the mixing and stirring effect, prevent cotton fibers from sliding along the central axis of the first rubber rod 18 and the second rubber rod 24, and improve practicality.
[0051] To facilitate the removal of cotton fibers adhering to the inner wall of the secondary mixing chamber 4; such as Figure 5-7 As shown, a planar spiral spring 26 is welded to the outer circumference of the rotating main shaft 27. An annular elastic bladder 23 is bonded to one end of the planar spiral spring 26, and the outer circumference of the annular elastic bladder 23 is integrally provided with evenly distributed locking posts 30. The inner wall of the secondary mixing chamber 4 has a locking groove adapted to the locking posts 30. The annular elastic bladder 23 is locked into the locking groove of the secondary mixing chamber 4 by the locking posts 30. The outer circumference of the annular elastic bladder 23 has evenly distributed air holes 32. By setting up the planar spiral spring 26, the annular elastic bladder 23, and the locking posts 30, it is possible to... When the main shaft 27 rotates, the planar spiral spring 26 stores energy. When the planar spiral spring 26 stores energy to a certain extent, the annular elastic bladder 23 deforms to cause the locking pin 30 to disengage from the locking groove of the secondary mixing chamber 4, causing the annular elastic bladder 23 to rotate rapidly. During the deformation and rotation of the annular elastic bladder 23, a large amount of airflow is generated near the annular elastic bladder 23 and its air hole 32, thereby shaking off the cotton wool adhering to the inner wall of the secondary mixing chamber 4 and the surface of the annular elastic bladder 23, avoiding material residue and improving the reliability of material mixing.
[0052] To facilitate the removal of cotton fibers from the roller 11; such as Figure 2 , Figure 3 As shown, the opening mechanism includes a cylinder 14 and a roller 11 adapted to the cylinder 14. An opening motor 8 is fixed to one side of the outer wall of the opening device 1 by screws. One end of the outer wall of the cylinder 14 is rotatably connected to the output end of the opening motor 8 by a coupling. The top of the opening device 1 has an arc-shaped structure, and the inner wall of the top of the opening device 1 is fitted with evenly distributed elastic columns 13 by screws. Each elastic column 13 is provided with a brush head 15 adapted to the roller 11 near one end. By setting the elastic columns 13 and the brush head 15, when the cylinder 14 and the roller 11 are working, the rotation of the roller 11 can make its surface contact the brush head 15, thereby brushing off the cotton wool attached to the surface of the roller 11, thus improving practicality.
[0053] To avoid excessive lint adhering to the brush head 15; such as Figure 3As shown, the elastic column 13 has evenly distributed annular grooves 16 on its outer circumference. The elastic column 13 has a hollow structure inside, and an oscillating spring 17 is provided between the inner wall of one end of the elastic column 13 and the inner wall of one side of the loosening device 1. By setting the annular grooves 16 and the oscillating springs 17, when the roller 11 contacts the brush head 15, the elastic column 13 is deformed under the force applied by the roller 11. As the roller 11 rotates continuously, the elastic column 13 intermittently contacts and separates from the roller 11, so that the elastic column 13 oscillates through the annular grooves 16 and the oscillating springs 17, thereby shaking off the cotton wool attached to the surface of the elastic column 13 and the brush head 15, further improving its practicality.
[0054] To improve conveying efficiency; such as Figure 1 As shown, the outer wall of the feeding conveyor belt 9 is integrally provided with equally spaced strip protrusions 10; by setting the strip protrusions 10, the passing cotton fibers can be carried, so that the finer impurity particles fall into the gaps between the strip protrusions 10, thereby achieving the purpose of screening and further ensuring product quality.
[0055] To facilitate further processing of the combed materials; such as Figure 1 , Figure 8 As shown, the conveyor platform 33 has a conveyor belt 12 for conveying materials installed on the inner wall of its top. A hot roller chamber is also provided on the top of the conveyor platform 33, containing a hot press roller 34 for hot pressing. Insulation curtains 35 for heat preservation are installed on the outer walls of both sides of the hot roller chamber. A cold press roller 36 for cold pressing is installed on the top of the conveyor platform 33 via a cold roller mounting frame. Cooling fans 37 arranged linearly are installed on the conveyor platform 33 via a fan bracket. The cold press roller 36 is located between the hot press roller 34 and the cooling fans 37. A cutting device 39 for cutting the insulation cotton to the target size is provided on the top of the conveyor platform 33, and a winding mechanism for winding the finished insulation cotton is provided on one side of the cutting device 39. By setting up structures such as the hot press roller 34 and the cold press roller 36, the combed insulation cotton can undergo hot pressing, cold pressing, fan cooling, cutting, and winding processes sequentially to obtain the target product. The entire process is orderly and reliable.
[0056] To facilitate better winding of the insulation cotton; such as Figure 9As shown, the winding mechanism includes a winding frame 40 and a winding roller 38. Two winding rods 41 are detachably installed on the outer walls of both sides of the winding roller 38. A lifting spring 43 is welded to the inner wall of the top of the winding frame 40. A lifting seat 42 is welded to the bottom of each lifting spring 43. The lifting seat 42 slides between the inner walls of both sides of the winding frame 40. The winding roller 38 is detachably and rotatably inserted into the inner wall of the lifting seat 42 through the winding rods 41. By setting up the winding roller 38, lifting springs 43, and other structures, the insulation cotton can be in closer contact with the winding roller 38 based on the pressure of the lifting springs 43. This allows the winding roller 38 to rotate as the insulation cotton progresses during winding, eliminating the need for continuous manual pressing and saving manpower.
[0057] In this embodiment, the user feeds the material through the feeding conveyor belt 9. After the material is opened by the opening mechanism in the opening device 1, it is sent into the mixing chamber 2. After the various materials are mixed once in the mixing chamber 2, they are sent to the pneumatic conveying channel 3. The pneumatic conveying channel 3 further sends the material from the mixing hopper 7 into the secondary mixing chamber 4. By setting the first rubber rod 18 and the first annular plate 22, the mixing motor 28 can drive the rotating main shaft 27 to rotate, which in turn drives the first rubber rod 18 and the second rubber rod 24 to rotate, achieving more thorough secondary mixing. The material is then sent into the baking chamber 5 for baking under the continuous air output of the pneumatic conveying channel 3. After baking, the material is sent to the carding machine 6 for carding and then output to the conveying platform 33. With the cooperation of the hot pressing roller 34, the feeding conveyor belt 12, and the cold pressing roller 36, the hot pressing, cold pressing, fan cooling, cutting and winding processes are carried out in sequence to obtain the target product. The whole process is orderly and reliable.
[0058] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
