Description

Technical Field

[0001] This utility model relates to the field of opening machine technology, specifically an opening machine for nonwoven fabric processing. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, needle-punched non-woven fabric, etc., is made of polyester fiber. In the production process, an opening machine is needed, which is a piece of equipment to loosen the compressed and entangled fiber raw materials and remove impurities.

[0003] According to a public announcement of a nonwoven fabric opening machine with a linkage function on the output shaft (Announcement No.: CN219547176U), the above application includes an opening device, a push plate and a receiving plate. The push plate is provided at the input end of the opening device, and the receiving plate is provided below the push plate. A high-performance drive motor is provided outside the opening device. The high-performance drive motor is fixedly connected to the opening device, and the output end of the high-performance drive motor is provided with an output shaft.

[0004] However, in actual use, the pusher plate of the above-mentioned opening machine should smoothly feed the raw material into the opening device. But if the raw material is too piling up, the pusher plate can only lift up part of the material. The raw material cannot enter the opening device continuously and evenly. At the same time, when the piling is serious, the operator may try to manually clean the feed inlet, which poses a risk of being pinched by the pusher plate or the linkage mechanism, especially when the opening machine is running. In view of this, we propose an opening machine for non-woven fabric processing. Utility Model Content

[0005] The purpose of this invention is to provide an opening machine for nonwoven fabric processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nonwoven fabric opening machine, comprising an opening machine body, a drive motor fixedly connected to the side wall of the opening machine body, a feeding assembly provided on the side wall of the opening machine body, the feeding assembly including a feeding hopper fixedly connected to the side wall of the opening machine body, a pre-carding roller rotatably connected to the side wall of the feeding hopper, a gear fixedly connected to the end face of the pre-carding roller, a rotating rod rotatably connected to the side wall of the feeding hopper, and an elastic rod fixedly connected to the outer wall of the rotating rod.

[0007] Preferably, a second drive motor is fixedly connected to the side wall of the feeding hopper, and a pulley is fixedly connected to the output shaft of the second drive motor and the side wall of the pre-carding roller. The pulley is connected to a belt, and the second drive motor drives the pre-carding roller to rotate through the belt. The rotation of the pre-carding roller conveys the nonwoven fabric raw material to the input end of the opening machine body.

[0008] Preferably, a second pulley is fixedly connected to the side wall of the pre-carding roller and the rotating rod. The second pulley is connected to a second belt for transmission. The rotation of the pre-carding roller through the second belt drives the rotating rod to rotate.

[0009] Preferably, the output end of the drive motor is connected to the opening roller, and the opening roller is rotatably connected to the inner wall of the opening machine body. The opening roller opens the input nonwoven fabric raw material.

[0010] Preferably, the top of the feeding hopper is shaped like a bucket, and the end of the feeding hopper away from the bucket shape is fixedly connected to the input end of the opening machine body. The bucket-shaped feeding hopper automatically guides the nonwoven fabric raw material under the action of gravity, so that the nonwoven fabric raw material enters the conveying channel along the bucket shape and finally enters the opening machine body.

[0011] Preferably, there are two sets of pre-carding rollers and rotating rods, which are symmetrically arranged below the bucket shape. The gears fixed to the end faces of the two sets of pre-carding rollers mesh with each other, and the two sets of pre-carding rollers rotate in opposite directions, so that the two sets of pre-carding rollers can synchronously convey the nonwoven fabric raw materials.

[0012] Preferably, a fixing frame is fixedly connected to the side wall of the feeding hopper, the fixing frame is inserted into the vertical rod, a feeding cone is fixedly connected to the bottom end of the vertical rod, a pull rope is fixedly connected to the top end face of the feeding cone, and a pull ring is fixedly connected to the end face of the pull rope. Pulling the pull rope and then releasing it causes the feeding cone to fall under the action of gravity, pushing the raw material toward the pre-carding roller.

[0013] Preferably, a limiting plate is fixedly connected to the top of the vertical rod, a sleeve rod is fixedly connected to the side wall of the feeding hopper, a roller is rotatably connected to the top end face of the fixing frame, the roller is movably connected to the pull rope, and the limiting plate limits the lowest position where the feeding cone can fall.

[0014] Compared with the prior art, this utility model provides an opening machine for nonwoven fabric processing, which has the following beneficial effects: 1. This nonwoven fabric processing opening machine, through its feeding assembly, features two sets of symmetrically arranged pre-carding rollers with meshing gears on their end faces, rotating in opposite directions. This ensures that the raw material is subjected to balanced force during conveying, preventing uneven material distribution or blockage, and improving the stability and continuity of feeding. During the rotation of the pre-carding rollers and rotating rods, the elastic rod continuously strikes the outer wall of the feeding hopper, vibrating the nonwoven fabric raw material in the hopper. This vibration can break up the accumulated fibers, preventing fiber agglomeration, thus ensuring that the raw material smoothly enters the conveying channel, avoiding blockage or uneven feeding, preventing fiber accumulation or blockage, and improving feeding efficiency.

[0015] 2. This nonwoven fabric processing opening machine uses a feeding cone to push the nonwoven fabric raw material in the feeding hopper towards the pre-carding roller, thereby achieving quantitative feeding of the raw material. This allows the fibers accumulated at the bottom of the feeding hopper to flow evenly to the pre-carding roller. Combined with the rotation of the pre-carding roller and the rotating rod, continuous and stable raw material conveying is achieved. Attached Figure Description

[0018] like Figures 1-4 As shown, this utility model provides a technical solution: a nonwoven fabric opening machine, including an opening machine body 1, a drive motor 2 fixedly connected to the side wall of the opening machine body 1, a feeding assembly 3 provided on the side wall of the opening machine body 1, the feeding assembly 3 including a feeding hopper 301 fixedly connected to the side wall of the opening machine body 1, a pre-carding roller 302 rotatably connected to the side wall of the feeding hopper 301, a gear 303 fixedly connected to the end face of the pre-carding roller 302, a rotating rod 304 rotatably connected to the side wall of the feeding hopper 301, and an elastic rod 305 fixedly connected to the outer wall of the rotating rod 304.

[0019] In one embodiment of this utility model, a second drive motor 308 is fixedly connected to the side wall of the feeding hopper 301. The output shaft of the second drive motor 308 is fixedly connected to a pulley 1 to the side wall of the pre-carding roller 302. The pulley 1 is connected to a belt 306 for transmission. The second drive motor 308 is able to drive the pre-carding roller 302 to rotate through the belt 306. The rotation of the pre-carding roller 302 conveys the nonwoven fabric raw material to the input end of the opening machine body 1.

[0020] The pre-carding roller 302 is fixedly connected to the side wall of the rotating rod 304 by a pulley 2. The pulley 2 is connected to the belt 2 307 for transmission. The pre-carding roller 302 rotates through the belt 2 307, which drives the rotating rod 304 to rotate.

[0021] The output end of the drive motor 2 is connected to the opening roller drive, and the opening roller is rotatably connected to the inner wall of the opening machine body 1. The opening roller opens the input non-woven fabric raw material.

[0022] The top of the feeding hopper 301 is shaped like a bucket. The end of the feeding hopper 301 away from the bucket shape is fixedly connected to the input end of the opening machine body 1. The feeding hopper 301, which is shaped like a bucket, automatically guides the non-woven fabric raw material under the action of gravity, so that the non-woven fabric raw material enters the conveying channel along the bucket shape and finally enters the opening machine body 1.

[0023] There are two sets of pre-carding rollers 302 and rotating rods 304. The two sets of pre-carding rollers 302 and rotating rods 304 are symmetrically arranged below the bucket shape. The gears 303 fixed to the end faces of the two sets of pre-carding rollers 302 mesh with each other. The two sets of pre-carding rollers 302 rotate in opposite directions and simultaneously convey the nonwoven fabric raw materials.

[0024] Drive motor 2 308 starts, and its output shaft is driven by pulley 1 and belt 1 306 to rotate the pre-carding roller 302. Driven by the pre-carding roller 302, the non-woven fabric raw material enters the input end of the opening machine body 1 from the feeding hopper 301 along the bucket-shaped channel, realizing the smooth conveying of the raw material. The non-woven fabric raw material conveyed by the feeding hopper 301 and the pre-carding roller 302 enters the opening machine body 1, and the opening roller is driven by drive motor 2 to rotate and open the raw material. The opening roller fully loosens the raw material, so that the fibers are dispersed to provide uniform and loose fiber material for subsequent processes. The end face gears 303 of the two symmetrically arranged pre-carding rollers 302 mesh with each other and rotate in opposite directions, so that the raw material is subjected to balanced force during the conveying process, avoiding material deviation or blockage, and improving the stability and continuity of the feeding.

[0025] The pre-carding roller 302 and the rotating rod 304 of the feeding hopper 301 are linked by pulley two and belt two 307 to realize the synchronous rotation of the rotating rod 304. During the rotation of the pre-carding roller 302 and the rotating rod 304, the elastic rod 305 continuously knocks on the outer wall of the feeding hopper 301 to vibrate the non-woven fabric raw material in the feeding hopper 301. This vibration can break up the accumulated fibers and prevent the fibers from agglomerating, thereby ensuring that the raw material enters the conveying channel smoothly, avoiding blockage or uneven feeding, preventing fiber accumulation or blockage, and improving feeding efficiency.

[0026] In addition, a fixed frame 4 is fixedly connected to the side wall of the feeding hopper 301. The fixed frame 4 is inserted into the vertical rod 5. A feeding cone 6 is fixedly connected to the bottom end of the vertical rod 5. A pull rope 8 is fixedly connected to the top end face of the feeding cone 6. A pull ring 9 is fixedly connected to the end face of the pull rope 8. Pulling the pull rope 8 and then releasing it causes the feeding cone 6 to fall under the action of gravity, pushing the raw material toward the pre-combing roller 302. A limit plate 7 is fixedly connected to the top end of the vertical rod 5. A sleeve rod 10 is fixedly connected to the side wall of the feeding hopper 301. A roller 11 is rotatably connected to the top end face of the fixed frame 4. The roller 11 is movably connected to the pull rope 8. The limit plate 7 limits the lowest position where the feeding cone 6 can fall.

[0027] The operator pulls the pull rope 8, causing the feeding cone 6 to rise. When released, the feeding cone 6 falls along the vertical rod 5 under its own weight. During the fall, the feeding cone 6 pushes the nonwoven fabric raw material in the feeding hopper 301 towards the pre-carding roller 302, achieving quantitative feeding of the raw material. The fall of the feeding cone 6 is controlled by the limit plate 7, which limits the lowest position of the feeding cone 6 to ensure that the feeding cone 6 does not fall excessively, while ensuring stable and accurate feeding action. Under the action of gravity, the feeding cone 6 pushes the raw material, so that the fibers accumulated at the bottom of the feeding hopper 301 flow evenly to the pre-carding roller 302. With the rotation of the pre-carding roller 302 and the rotating rod 304, continuous and stable raw material conveying is achieved, avoiding feeding blockage and ensuring that the opening machine continuously obtains raw materials.

[0028] Pull the pull rope 8, then wrap the pull rope 8 around the sleeve rod 10 and tie a knot to fix the feeding cone 6 above the feeding hopper 301, thereby fixing the position of the feeding cone 6.

[0029] In this invention, during use, the second drive motor 308 starts, and its output shaft is driven by the first pulley and the first belt 306, causing the pre-carding roller 302 to rotate. Driven by the pre-carding roller 302, the non-woven fabric raw material enters the input end of the opening machine body 1 from the feeding hopper 301 along the bucket-shaped channel. The pre-carding roller 302 and the rotating rod 304 of the feeding hopper 301 are linked by the second pulley and the second belt 307 to realize the synchronous rotation of the rotating rod 304. During the rotation of the pre-carding roller 302 and the rotating rod 304, the elastic rod 305 continuously strikes the outer wall of the feeding hopper 301 to vibrate the raw material and keep the fibers loose. The end face gears 303 of the two symmetrically arranged pre-carding rollers 302 mesh with each other and rotate in opposite directions, so that the raw material is subjected to balanced force during the conveying process. Finally, it enters the opening machine body 1, where the first drive motor 2 drives the opening roller to open and loosen the fibers, so that the fibers are loosened and dispersed, and the raw material is conveyed evenly for subsequent processes.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
