Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Specific examples are given below.

[0025] like Figures 1 to 3As shown, a hot air non-woven fiber opening device described in an embodiment of the utility model comprises an opening machine body 1; a conveyor belt 11 is fixedly connected to the side wall of the opening machine body 1; a processing box 12 is fixedly connected to the end of the conveyor belt 11; a motor 13 is fixedly connected to the side wall of the processing box 12; a rotating shaft 14 is fixedly connected to the output end of the motor 13; a plurality of levers 15 are fixedly connected to the side wall of the rotating shaft 14; a first fixed frame 16 is fixedly connected to the inner wall of the processing box 12; and the inner wall of the first fixed frame 16 is fixedly connected to the inner wall of the processing box 12. A plurality of springs 17 are connected; a first filter screen 18 is fixedly connected to the ends of the plurality of springs 17; a vibration motor 19 is fixedly connected to the bottom of the first filter screen 18; a first notch 110 is provided on the side wall of the processing box 12; an electric push rod 111 is fixedly connected to the side wall of the processing box 12; a push plate 112 is fixedly connected to the end of the electric push rod 111; a second notch 113 is provided on the side wall of the processing box 12; during operation, when the non-woven fabric fibers are opened and loosened, the fiber mass is placed in the processing box 12, Then, the motor 13 is started to drive the rotating shaft 14 and the lever 15 to rotate simultaneously. At this time, the lever 15 can break up the fiber clumps, and the broken fiber clumps fall to the surface of the first filter screen 18 below. At this time, the vibration motor 19 is started to drive the first filter screen 18 to vibrate, which can drive the fibers on the surface of the first filter screen 18 to vibrate and filter out some impurities mixed in the fiber clumps. Then, the electric push rod 111 is started to drive the push plate 112 to move toward the first slot 110, so that the fibers on the surface of the first filter screen 18 can be pushed from the electric push rod 111 to the conveyor belt 11, and then the conveyor belt 11 transports the fibers to the inside of the opener body 1 for opening processing. In this step, the motor 13 is set to drive the lever 15 to break up the fiber clumps and disperse the fiber clumps, so as to reduce the situation where the fiber clumps enter the opener body 1 in a large clumping state and cause blockage. The vibration motor 19 drives the first filter screen 18 to vibrate and filter out some impurities mixed in the fibers, so as to reduce the situation where more impurities are mixed in the fibers and affect the finished product effect after the fibers are opened.

[0026] like Figure 2 As shown, an elastic rope 2 is fixedly connected between the two mutually adjacent levers 15; a counterweight block 21 is fixedly connected to the middle of the elastic rope 2; during operation, when the lever 15 rotates, the elastic rope 2 and the counterweight block 21 can be driven to rotate simultaneously. The elastic rope 2 is an elastic structure and will be deformed and swung due to the gravity of the counterweight block 21 during rotation. When the counterweight block 21 contacts the fiber mass, the fiber mass can be beaten to disperse the fiber mass. In this step, the lever 15 is set to connect the elastic rope 2 and the counterweight block 21, so as to beat and disperse the fiber mass in the processing box 12, so as to reduce the situation where the fiber mass is large and enters the opener body 1, causing blockage and difficulty in opening.

[0027] like Figure 1As shown, a collecting groove 3 is provided on the side wall of the processing box 12; a collecting box 31 is provided on the inner wall of the processing box 12; a pull-out box 32 is placed on the inner wall of the collecting box 31; the collecting box 31 and the pull-out box 32 are slidably matched; during operation, when the fiber is filtered at the first filter screen 18, the filtered impurities will fall from the first filter screen 18 to the collecting box 31 below; the pull-out box 32 is located inside the collecting box 31, at which time the pull-out box 32 can collect the filtered impurities, and when the collection is completed, the pull-out box 32 is pulled out of the collecting box 31, the collected impurities are poured out, and then the pull-out box 32 is put back into the collecting box 31. In this step, the impurities filtered out of the fiber can be collected by setting the pull-out box 32, and the pull-out and put-back design of the pull-out box 32 facilitates the removal of the collected impurities to improve the convenience of impurity collection.

[0028] like Figure 1 and Figure 4 As shown, the side wall of the conveyor belt 11 is fixedly connected to a fixing frame 4; the side wall of the fixing frame 4 is fixedly connected to a bellows 41; the inner wall of the bellows 41 is fixedly connected to a fan 42; the inner wall of the bellows 41 is fixedly connected to an electric heating pipe 43; the electric heating pipe 43 is arranged near the bottom of the fan 42; the bottom of the bellows 41 is provided with a plurality of air outlet holes 44; the top of the bellows 41 is provided with a plurality of air inlet holes 45; when working, the fan 42 can be started when the fiber is transported from the surface of the conveyor belt 11 to the inside of the opener body 1 The air flow is driven to enter the fixed frame 4 from the air inlet 45. At this time, the electric heating tube 43 can be energized to generate heat. When the air flow passes through the electric heating tube 43, it will be heated. Then the air flow blows toward the fiber surface from the air outlet 44 below to heat the fiber transported on the surface of the conveyor belt 11. In this step, the fan 42 and the electric heating tube 43 are set to blow and heat the fiber transported on the surface of the conveyor belt 11 to increase the temperature of the fiber so that it becomes more fluffy and easier to be loosened, thereby improving the effect of loosening the fiber.

[0029] like Figure 4 As shown, a second fixed frame 5 is fixedly connected to the bottom of the bellows 41; a plurality of guide plates 51 are fixedly connected to the inner wall of the second fixed frame 5; the guide plates 51 are symmetrically arranged; during operation, when the airflow blows from the air outlet 44 to the fiber surface, it will pass through the second fixed frame 5 and the guide plates 51. At this time, the guide plates 51 are inclined to both sides to disperse the passing airflow, so as to expand the range of the airflow so that the heated airflow can contact the fibers on the surface of the conveyor belt 11 more widely. In this step, the hot airflow blown out from the air outlet 44 can be dispersed by setting the second fixed frame 5 and the guide plates 51, so as to increase the flow range of the airflow and increase the contact range with the fibers, so as to improve the heating effect on the fibers and facilitate the loosening process.

[0030] like Figure 4As shown, a pair of connecting rods 6 are fixedly connected to the side wall of the fixing frame 4; a second filter screen 61 is fixedly connected to the end of the connecting rod 6; during operation, when the fibers are blown, some floating fibers will be generated, and at this time, the second filter screen 61 will block some of the floating fibers to reduce the situation where the fibers float from the bottom to the guide plate 51 and cause blockage. In this step, by setting the second filter screen 61, it is possible to reduce the situation where the floating fibers float from the bottom to the guide plate 51, causing adhesion between the guide plates 51 to cause blockage and affect the dispersion of the airflow.

[0031] like Figure 5 As shown, the inner wall of the collection box 31 is rotatably connected to a plurality of ball bearings 7; during operation, when the pull-out box 32 is taken out of and put back into the collection box 31, the ball bearings 7 are in contact with the bottom surface of the pull-out box 32 when the pull-out box 32 moves, and rotation occurs. In this step, by setting the ball bearings 7 in contact with the bottom surface of the pull-out box 32, rotation occurs simultaneously when the pull-out box 32 is taken out or put back, so as to reduce the friction between the pull-out box 32 and the collection box 31 and improve the convenience of taking out and putting back the pull-out box 32.

[0032] Working principle: During operation, when the non-woven fabric fibers are being loosened, the fiber mass is placed in the processing box 12, and then the motor 13 is started to drive the rotating shaft 14 and the lever 15 to rotate simultaneously. At this time, the lever 15 can break up the fiber mass, and the broken fiber mass falls to the surface of the first filter screen 18 below. At this time, the vibration motor 19 is started to drive the first filter screen 18 to vibrate, which can drive the fibers on the surface of the first filter screen 18 to vibrate and filter out some impurities mixed in the fiber mass. Then the electric push rod 111 is started to drive the push plate 112 to move toward the first notch 110 to filter out the surface of the first filter screen 18. The fiber is pushed from the electric push rod 111 onto the conveyor belt 11, and then the conveyor belt 11 transports the fiber to the inside of the opener body 1 for opening processing. When the lever 15 rotates, it can drive the elastic rope 2 and the counterweight block 21 to rotate at the same time. The elastic rope 2 is an elastic structure. When it rotates, it will be deformed and swung due to the gravity of the counterweight block 21. When the counterweight block 21 contacts the fiber group, the fiber group can be beaten to disperse the fiber group. When the fiber is filtered at the first filter screen 18, the filtered impurities will fall from the first filter screen 18 to the collection box 31 below. The pull-out box 32 is located in the collection box 31 At this time, the pull-out box 32 can collect the filtered impurities. When the collection is completed, the pull-out box 32 is pulled out from the collection box 31 to pour out the collected impurities and then put the pull-out box 32 back into the collection box 31. When the fiber is transported from the surface of the conveyor belt 11 to the opener body 1, the fan 42 can be started to drive the airflow from the air inlet 45 into the fixed frame 4. At this time, the electric heating tube 43 can be energized to generate heat. When the airflow passes through the electric heating tube 43, it will be heated, and then the airflow is blown to the fiber surface from the air outlet 44 below, which can heat the fiber transported on the surface of the conveyor belt 11. When the airflow is from the air outlet 4 4 will pass through the second fixed frame 5 and the guide plate 51 when blowing toward the fiber surface. At this time, the guide plate 51 is inclined to both sides to disperse the passing airflow, so as to expand the range of the airflow so that the heated airflow can contact the fibers on the surface of the conveyor belt 11 more widely. When blowing the fibers, some floating fibers will be generated. At this time, the second filter screen 61 will block some of the floating fibers to reduce the situation where the fibers float from the bottom to the guide plate 51 and cause blockage. When the pull-out box 32 is taken out of the collection box 31 and put back, when the pull-out box 32 moves, the ball 7 contacts the bottom surface of the pull-out box 32 and rotates.
