Description

Technical Field

[0001] This invention relates to the field of cotton blending machine technology, and in particular to a high-efficiency circulating cotton blending machine. Background Technology

[0002] Fabrics made by blending or interweaving cotton with other fibers are collectively referred to as cotton blended or interwoven fabrics. This includes combinations of cotton with other natural fibers, as well as combinations of cotton with various synthetic fibers. Cotton is often combined with synthetic fibers to create a variety of patterns and varieties, resulting in practical fabrics that combine the advantages of both.

[0003] Patent application publication number CN209669408U discloses a high-efficiency circulating cotton mixing device, including a housing. Inside the housing are several vertically arranged stirring rollers in a circular array. Several stirring rods are circumferentially fixed to each stirring roller, with the stirring rods of adjacent rollers staggered. A cotton suction machine is located outside the housing. The cotton suction machine's inlet is connected to a first three-way pipe. One port of the first three-way pipe is connected to the bottom of the housing and has a third switching valve. One port of a second three-way pipe is connected to the top of the housing and has a second switching valve. The other port of the second three-way pipe is connected to a cotton storage box and has a first switching valve. This arrangement allows for more uniform cotton mixing. Furthermore, depending on the desired level of uniformity, the cotton suction machine repeatedly circulates the cotton into the housing for mixing.

[0004] Patent application publication number CN114411289A discloses a nonwoven fabric circulating blending machine, including a processing table with a support frame. A blending cylinder is fixedly connected to the support frame, and a rotating shaft is rotatably connected to the inner wall of the blending cylinder. A rotating disk is fixedly connected to the end of the rotating shaft, and multiple stirring shafts for stirring raw materials are arranged between two rotating disks. A self-rotating component is provided at one end of each stirring shaft, and multiple elastic threads are evenly arranged around the rotating disk, with picking components at both ends of each elastic thread. In mixing fiber raw materials, this invention achieves three key benefits: first, the rotating shaft drives the stirring shaft to rotate around the rotating shaft, thus driving the fiber raw materials; second, the rotation of the rotating shaft causes the stirring shaft itself to rotate, and the stirring blades on it effectively pull on the fiber raw materials, thereby achieving continuous mixing; and third, the elastic threads continuously move at high speed around the machine, cutting and mixing the fiber raw materials, further ensuring that the raw materials are evenly mixed.

[0005] However, in practical use, it still has the following drawbacks: after the workers mix the cotton fibers, some parts of the mixed fabric are still uneven after being taken out. Increasing the mixing time in the cotton blending machine will greatly reduce the mixing efficiency. Therefore, the unevenly mixed cotton material is usually fed back into the blending machine for multiple mixing cycles, but this still cannot avoid the problem of low efficiency, because it requires manual removal and re-feeding of the fabric. To address these issues, we propose a high-efficiency circulating cotton blending machine. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-efficiency circulating cotton blending machine, which can realize the circulating mixing of cotton fibers, take out the uniformly mixed fibers, and recycle the mixed parts with a large or small proportion of cotton fibers, thereby uniformly mixing cotton fibers with other fibers during the mixing process, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency circulating cotton blending machine, comprising a cutting box and a mixing box arranged sequentially from front to back, characterized in that: the cutting box and the mixing box are connected by a connecting pipe, a return pipe is provided above the cutting box, one end of the return pipe is connected to the top inclined surface of the cutting box, and the other end of the return pipe is connected to the top arc surface of the mixing box, the return pipe generates suction through a negative pressure pump installed at the top to draw cotton material from the mixing box into the cutting box, and a second cotton outlet is opened at the bottom middle part of the mixing box to facilitate material discharge;

[0008] The top of the cutting box is inclined and has a cotton return inlet at the position corresponding to the end of the return pipe. The mixing box is composed of two cylindrical cavities connected together. The top of the cylindrical cavity away from the cutting box is connected to the cotton return outlet. The mixing box has a second cotton inlet near the connecting pipe and the second cotton outlet is located at the bottom middle of the position where the two cylindrical cavities are connected.

[0009] The mixing chamber is equipped with a mixing mechanism, which includes two drive shafts. The two drive shafts are located inside two cylindrical cavities of the mixing chamber and are connected by a transmission assembly. Several guide blocks are distributed in a circular array on the outer side of the drive shafts. The guide blocks and the drive shafts are fixedly connected by several first connecting rods. One of the drive shafts is fixedly connected to the output end of a second servo motor on the outside of the mixing chamber through a connecting shaft.

[0010] The transmission assembly includes a first pulley and a second pulley respectively mounted on a connecting shaft at one end of two drive shafts. The first pulley and the second pulley are connected by a synchronous belt, which is arranged in a V-shape.

[0011] In a preferred embodiment, a first cotton inlet is provided on the bottom side of the cutting box for feeding, and a first cotton outlet is provided on the other side of the mixing box at the position corresponding to the end of the connecting pipe. A cutting mechanism for cutting cotton fibers is installed inside the cutting box, and the cutting mechanism is driven by a first servo motor installed on the side wall of the cutting box.

[0012] In a preferred embodiment, the cutting mechanism includes several drive shafts arranged parallel to each other along the inclined plane, several sets of second connecting rods are equidistantly distributed on the outside of the drive shafts, each set of second connecting rods is arranged in a circumferential array around the drive shaft, a rotating rod is installed between the second connecting rods at corresponding positions of two adjacent sets of drive shafts, and several cutting strips are evenly distributed on the outside of the rotating rods.

[0013] In a preferred embodiment, the number of drive shafts is set to three, with the first drive shaft and the third drive shaft being connected by a transmission belt, a third pulley, and a fourth pulley.

[0014] In a preferred embodiment, one end of one of the drive shafts is fixedly connected to the output end of the first servo motor via a connecting shaft, and the other end extends to the other side of the cutting box via a connecting shaft to connect to the third pulley. The third drive shaft also extends to the other side of the cutting box via a connecting shaft to connect to the fourth pulley. The third pulley and the fourth pulley are connected by a transmission belt.

[0015] In a preferred embodiment, drive gears are installed at the ends of the first and second drive shafts near the first servo motor, and a bridge gear is installed on one side wall of the cutting box between the two drive gears, with the number of bridge gears set to an even number.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. Through the overall structure designed in this invention, compared with the existing technology for unevenly mixed fibers, the cotton fibers can be cyclically mixed. The uniformly mixed fibers can be taken out and the mixed parts with a large or small proportion of cotton fibers can be recycled. In this way, the cotton fibers are evenly mixed with other fibers during the mixing process, without the need to manually add cotton fibers again, thereby improving the efficiency of the cotton mixing process and the degree of mixing between cotton fibers and other fibers.

[0018] The mixing mechanism designed in this invention uses two driving shafts that rotate in opposite directions. These shafts drive the first connecting rod and the guide block to rotate. The guide block and the cylindrical inner cavity of the mixing box flatten the fiber mixture, thereby increasing the density of the mixed fibers. In addition, the mixed fibers are separated at the point where the two cylindrical cavities are close to each other, and the mixed cotton fibers that meet the mixing density are taken out. The mixed fibers with a lower proportion of cotton fibers continue to rotate along the guide block to facilitate further mixing with subsequent cotton fibers. The mixed fibers with a higher proportion of cotton fibers return upwards to the cutting box through the return cotton outlet to facilitate subsequent mixing. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] As attached Figure 1-9 The high-efficiency circulating cotton blending machine shown includes a cutting box 1 and a mixing box 2 arranged sequentially. The cutting box 1 and the mixing box 2 are connected by a connecting pipe 3. A return pipe 4 is installed above the cutting box 1. One end of the return pipe 4 is connected to the top inclined surface of the cutting box 1, and the other end is connected to the top arc surface of the mixing box 2. The return pipe 4 generates suction through a negative pressure pump 7 installed at the top, which draws cotton material from the mixing box 2 into the cutting box 1. A second cotton outlet 6 is opened at the bottom middle of the mixing box 2 to facilitate material discharge. The fan of the return pipe 4 generates a large suction inside the mixing box 2, which facilitates the gradual entry of cotton material from the cutting box 1 into the mixing box 2. The operator adds the cotton material to be mixed into the cutting box 1 through the first cotton inlet 14. Inside box 1, the cotton material is then cut into smaller fiber segments by the cutting mechanism 9 for initial mixing. The initially mixed cotton material enters the mixing box 2 through the connecting pipe 3 and is further mixed by the mixing mechanism 5. Then, the negative pressure pump 7 is activated, which generates an upward suction force in the mixing box 2. At the same time, the second cotton outlet 6 is opened. Under the action of gravity, the part of the cotton material that is evenly mixed with other fibers will fall and be taken out from the second cotton outlet 6. The part of the mixture with more cotton fibers will be attracted upward and move into the return pipe 4. The part of the mixture with smaller cotton fibers will be driven by the mixing mechanism 5 to flow to both sides inside the mixing box 2 and will be continuously mixed with other cotton fibers as the mixing mechanism 5 rotates.

[0033] For detailed instructions, please refer to Figure 3-4 A first cotton inlet 14 for feeding is opened on the bottom side of the cutting box 1, and a first cotton outlet 13 is opened on the other side of the mixing box 2 at the position corresponding to the end of the connecting pipe 3. A cutting mechanism 9 for cutting cotton fibers is installed inside the cutting box 1. The cutting mechanism 9 is driven by a first servo motor 8 installed on the side wall of the cutting box 1. The operator injects the cotton material to be mixed and other materials into the cutting box 1 through the first cotton inlet 14. Inside the cutting mechanism 9, the cotton fibers are cut into smaller segments that are easier to separate, and then leave the cutting box 1 through the first cotton outlet 13.

[0034] Reference Figure 5 The cutting mechanism 9 in this embodiment is described in detail below. The cutting mechanism 9 includes several drive shafts 91 arranged parallel to each other along the inclined plane. Several sets of second connecting rods 92 are equidistantly distributed on the outside of the drive shafts 91. Each set of second connecting rods 92 is arranged in a circumferential array around the drive shaft 91. A rotating rod 93 is installed between the second connecting rods 92 at corresponding positions of two adjacent sets of drive shafts 91. Several cutting strips 94 are evenly distributed on the outside of the rotating rod 93. During the rotation of the drive shafts 91, the second connecting rods 92 are driven to rotate together. The second connecting rods 92 drive the rotating rods 93 to rotate. During the rotation, the cutting strips 94 can rotate with the rotating rods 93 and cut the cotton fibers through the rotating cutting strips 94.

[0035] Reference Figure 3 , 5 The number of drive shafts 91 is set to three. The first drive shaft 91 and the third drive shaft 91 are connected by a transmission belt 97, a third pulley 95 and a fourth pulley 96. When the first drive shaft 91 rotates, it drives the drive gear 10 to rotate. The rotation of the drive gear 10 drives the bridge gear 11 to rotate. Through the transmission of the two bridge gears 11, the drive gear 10 on the second drive shaft 91 is driven to rotate in the opposite direction, which facilitates the cutting of raw materials.

[0036] Continue to refer to Figure 3-5 Further explanation of the cutting mechanism 9: one end of a drive shaft 91 is fixedly connected to the output end of the first servo motor 8 via a connecting shaft, and the other end extends to the other side of the cutting box 1 via a connecting shaft to connect to the third pulley 95. The third drive shaft 91 also extends to the other side of the cutting box 1 via a connecting shaft to connect to the fourth pulley 96. The third pulley 95 and the fourth pulley 96 are connected by a transmission belt 97. Drive gears 10 are installed at the ends of the first drive shaft 91 and the second drive shaft 91 near the first servo motor 8. A bridge gear 11 is installed on one side wall of the cutting box 1 at the position between the two drive gears 10. The number of bridge gears 11 is set to an even number. When the first drive shaft 91 rotates, it drives the third pulley 95 to rotate, and at the same time, it drives the fourth pulley 96 to rotate via the transmission belt 97. The rotation of the first drive shaft 91 and the third drive shaft 91 are opposite.

[0037] Reference Figure 6The mixing box 2 in this embodiment will be specifically described. The top of the cutting box 1 is inclined and has a cotton return inlet 12 at the position corresponding to the end of the return pipe 4. The mixing box 2 is composed of two cylindrical cavities connected together. The top of the cylindrical cavity away from the cutting box 1 is connected to the cotton return outlet 16. The mixing box 2 has a second cotton inlet 15 near the connecting pipe 3. The second cotton outlet 6 is located at the bottom middle of the position where the two cylindrical cavities are connected. When the mixing mechanism 5 rotates, the cotton fibers enter from the second cotton inlet 15 and are mixed inside the two cylindrical cavities in the mixing box 2. At the same time, they are mixed and squeezed at the position where the cylindrical cavities are close to each other, thereby enhancing the mixing effect of the cotton fibers.

[0038] Reference Figure 8-9 The mixing mechanism 5 in this embodiment will be described in detail. The mixing mechanism 5 is installed inside the mixing box 2. The mixing mechanism 5 includes two drive shafts 52, which are located inside the two cylindrical cavities of the mixing box 2 respectively. The two drive shafts 52 are connected by a transmission assembly. Several guide blocks 54 are distributed in a circular array on the outer circumference of the drive shafts 52. The guide blocks 54 and the drive shafts 52 are fixedly connected by several first connecting rods 53. One of the drive shafts 52 is fixedly connected to the output end of the second servo motor 51 on the outside of the mixing box 2 through a connecting shaft. When the second servo motor 51 is started, it drives the drive shaft 52 to rotate. When the drive shaft 52 rotates, it drives the mixing fibers to mix.

[0039] Reference Figure 8-9 To further describe the mixing mechanism 5 in this embodiment, the transmission assembly includes a first pulley 55 and a second pulley 56 respectively mounted on the connecting shafts at the ends of the two drive shafts 52. The first pulley 55 and the second pulley 56 are connected by a synchronous belt 57, which is arranged in a figure-eight shape. When the connecting shaft connected to the drive shaft 52 rotates, it drives the first pulley 55 to rotate as well. When the first pulley 55 rotates, it drives the synchronous belt 57 to rotate, which in turn drives the second pulley 56 to rotate. This causes the two drive shafts 52 to rotate in opposite directions, thereby driving the cotton fibers and other fibers to mix inside the guide block 54. At the same time, a slight squeezing is performed at the position where the two drive shafts 52 are close together to facilitate the separation of the mixed fibers, and the uniformly mixed fibers are taken out from the second cotton outlet 6.
