Description

Technical Field

[0001] The utility model belongs to the technical field of production and processing of textiles, etc. Specifically, it relates to an automatic cotton mixer. Background Technique

[0002] An automatic cotton mixer is a mechanical device widely used in industries such as cotton processing and textile. It is mainly used to mix cottons of different varieties and grades to achieve a homogenizing effect, thereby improving the quality of cotton products.

[0003] The prior art discloses a cotton mixer with an automatic metering function (CN215366107U). The cotton mixer with an automatic metering function includes: a machine body; a feeding structure, the feeding structure is arranged at the top of the machine body, and the feeding structure includes a feeding hopper, a rotating motor, a rotating member, a rotating plate, a pressure sensor, and a discharge pipeline. The utility model provides a cotton mixer with an automatic metering function. By setting the feeding structure, the function of quickly adding raw materials quantitatively can be realized, changing the traditional quantitative feeding method. When the previous raw material is introduced into the machine body by driving the rotating member to rotate by the rotating motor, the other rotating plate can quickly form a collection area, and then people can immediately add the next raw material, greatly shortening the intermediate waiting time, thereby effectively accelerating the raw material adding speed and better meeting the cotton mixing processing requirements.

[0004] After retrieval, it is found that the prior art uses a stirring component to mix cotton when in use. This method has certain drawbacks when in use, mainly reflected in that the rotating method is easy to draw silk from the cotton, resulting in the cotton winding around the stirring component and causing damage to the device, thereby affecting the cotton mixing efficiency; furthermore, there is a lack of measures to oscillate the cotton to remove impurities in the prior art, which makes the cotton contain impurities and requires manual secondary impurity removal treatment, which is not only cumbersome in operation but also slows down the progress of the cotton mixing work.

[0012] As a preferred embodiment of the present invention, a sliding frame is slidably connected above the inside of the cotton mixing box. A threaded hole is opened at the center of the sliding frame. Three emptying rods are respectively fixedly connected to both sides of the center of the sliding frame. The sliding frame is threadedly connected to the top end of the double-headed screw rod through a threaded ring.

[0013] As a preferred embodiment of the present invention, the gear is rotatably arranged on the top surface of the cotton mixing box. The gear is in transmission engagement with the rack. An electric push rod is fixedly arranged on the top surface of the cotton mixing box. The output end of the electric push rod is connected to the side of the rack away from the gear.

[0014] As a preferred embodiment of the present invention, two support rods are symmetrically arranged. A roller is rotatably connected to each of the two support rods. Two sleeve columns are symmetrically fixed on the inner bottom surface of the cotton mixing box. Two sliding columns are symmetrically fixed on the bottom surface of the dust collection box. The sliding columns slide in the sleeve columns. A spring is fixedly arranged between the dust collection box and the cotton mixing box.

[0017] 1. By setting a double-headed lead screw, a mixing helix, an air-removing rod and a carriage, while the rack drives the gear to rotate reciprocally forward and backward, the double-headed lead screw drives the carriage to lift and lower reciprocally. The carriage drives the air-removing rod to stir the cotton in the mixing box up and down, removing the cavities between the cotton and swapping the positions of the upper and lower cotton at the same time. At the same time, the shape of the mixing helix itself can help different cotton to fall at different positions, mixing the cotton forward and backward while avoiding cotton entanglement, reducing equipment damage and thus improving the efficiency of cotton mixing.

[0018] 2. By setting a double-headed lead screw, a dust collection box and a sieve plate, the reciprocating forward and backward rotation of the double-headed lead screw can make the dust collection box move up and down continuously. With the cooperation of the sleeve column, the sliding column and the spring, it realizes up and down vibration. The inclined sieve plate sifts the impurities in the cotton into the dust collection box, and then uses the inclined design to help the cotton to be sent out. This not only removes the impurities in the cotton, avoids secondary treatment, simplifies the operation, but also speeds up the progress of the cotton mixing work.

The gear 23 is fixedly arranged on the top surface of the double-headed screw rod 21, the rack 24 is slidably arranged on the top surface of the cotton mixing box 10, the double-headed screw rod 21 is rotatably arranged in the cotton mixing box 10, the mixing spiral 22 is fixedly arranged on the curved surface of the double-headed screw rod 21, the emptying rod 20 is threadedly arranged at one end of the double-headed screw rod 21, and the dust collection box 25 is threadedly arranged at the other end of the double-headed screw rod 21; as Figure 1 shown, a feeding pipe 14 for feeding is fixedly connected to one side of the cotton mixing box 10, and a discharging pipe 13 for discharging is fixedly connected to one side of the cotton mixing box 10. The discharging pipe 13 is located on the opposite side of the feeding pipe 14.

[0029] Specifically, by setting the double-headed screw rod 21, the mixing spiral 22, and the emptying rod 20 in the mixing assembly of the device, while the rack 24 drives the gear 23 to rotate forward and backward reciprocally, the double-headed screw rod 21 drives the emptying rod 20 to lift and lower reciprocally. The emptying rod 20 stirs the cotton in the cotton mixing box 10 up and down, removes the cavities between the cotton and exchanges the positions of the upper and lower cotton at the same time. At the same time, the self-shape of the mixing spiral 22 can help different cotton to fall at different positions, mixing the cotton in both forward and reverse rotations and avoiding cotton entanglement, reducing device damage and thus improving the efficiency of cotton mixing. Cooperating with the dust collection box 25, the reciprocating forward and reverse rotation of the double-headed screw rod 21 can make the dust collection box 25 move up and down continuously, realizing up and down vibration, screening the impurities in the cotton into the dust collection box 25 and helping the cotton to be sent out. In this way, not only the impurities in the cotton are removed, avoiding secondary treatment, but also the operation is simplified while accelerating the progress of the cotton mixing work.

[0031] Specifically, two semi-circular holes and a circular hole are formed in the blanking plate 30. The smooth surface of the double-headed screw rod 21 rotates within the circular hole, and the mixing helix 22 is rotatably arranged on the top surface of the blanking plate 30. The cotton agitated by the mixing helix 22 falls through the two semi-circular holes.

[0032] As Figure 1 and Figure 3 shown, a carriage 19 is slidably connected above the interior of the cotton mixing box 10. A threaded hole is formed at the center of the carriage 19. Three emptying rods 20 are respectively and fixedly connected to both sides of the center of the carriage 19. The top end of the double-headed screw rod 21 is threadedly connected to the carriage 19 through a threaded ring.

[0033] Specifically, sliding grooves are symmetrically formed on the inner walls of the cotton mixing box 10 and the mixing box 18. Protrusions are arranged at both ends of the carriage 19, and the protrusions slide within the sliding grooves.

[0034] As Figure 1 and Figure 3 shown, a gear 23 is rotatably arranged on the top surface of the cotton mixing box 10. The gear 23 is in driving engagement with a rack 24. An electric push rod 11 is fixedly arranged on the top surface of the cotton mixing box 10, and the output end of the electric push rod 11 is connected to the side of the rack 24 away from the gear 23; As Figure 1 、 Figure 2 and Figure 4 shown, two support rods 29 are symmetrically arranged. A roller 15 is rotatably connected to each of the two support rods 29. Two sleeve columns 16 are symmetrically and fixedly arranged on the inner bottom surface of the cotton mixing box 10.
