[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] This invention provides a color bleach powder raw material mixing device with bleaching effect. When the color bleach powder raw material is put into the mixing device, it first enters the screen. When the motor is started, the crushing roller in the screen rotates and crushes the clumps of color bleach powder raw material under the rotation of the stirring rod. Then, the scraper in the screen scoops up the crushed raw material to prevent it from being crushed and blocked. At the same time, the brush inside the scraper can scrape the raw material in the holes and put it into the mixing chamber for mixing. While the motor is rotating, the first gear on the stirring rod drives the second gear to rotate. The push rod connected to the second gear through the rotating shaft makes an eccentric motion, which drives the push rod to make a back-and-forth motion. This causes the movable sleeve on the fixed rod to slide and hit the shaking plate on the screen that penetrates the chamber cover, making the screen vibrate and facilitating the crushed raw material to fall into the mixing chamber, which greatly increases the mixing efficiency.

[0027] like Figure 1-7As shown, this utility model discloses a mixing device for color-safe bleach powder raw materials with bleaching function, comprising: a mixing chamber 1 and a chamber cover 2. The chamber cover 2 is threadedly connected to the surface of the mixing chamber 1. A screen 3 is connected to the inside of the chamber cover 2 via a connecting rope. A swaying plate 10 is fixedly connected to the top of the screen 3. A second gear 12 is connected to the top of the chamber cover 2 via a bearing. A first fixing plate 16 is fixedly connected to the top of the chamber cover 2. A fixing rod 15 is fixedly connected to the surface of the first fixing plate 16. A motor 4 is located above the chamber cover 2. A stirring rod 5 is connected to the bottom of the motor 4 via a rotating rod. A cover 2 penetrates the surface of the stirring rod 5. A screen 3 is connected to the surface of the stirring rod 5 via a bearing. A connecting block 6 is fixedly connected to the surface of the stirring rod 5. A crushing cylinder 7 is connected to the surface of the connecting block 6 via a rotating shaft. A scraper 8 is fixedly connected to the surface of the connecting block 6. A first gear 11 is fixedly connected to the surface of the stirring rod 5. A second gear 12 is meshed with the surface of the first gear 11. A push rod 13 is connected to the surface of the second gear 12 via a rotating shaft. The other end of the push rod 13 is connected to a movable sleeve 14 via a rotating shaft. A fixed rod 15 is slidably connected to the inner side of the movable sleeve 14.

[0028] A material collection frame 20 is fixedly connected to the top of the hopper cover 2. A collection box 35 is fixedly connected to the surface of the material collection frame 20. A pull-out box 36 is inserted inside the collection box 35. A transmission belt 17 is connected to the bottom of the second gear 12 via a transmission wheel. A first transmission rod 18 is connected to the inside of the transmission belt 17 via a transmission wheel. A shaped turntable 19 is fixedly connected to the surface of the first transmission rod 18 via a bearing. The material collection frame 20 is fixedly connected to the bottom of the material collection frame 20. A second fixing plate 21 is fixedly connected to the bottom of the second fixing plate 21 via a spring. A strike rod 22 is connected to the surface of the second fixing plate 21. The surface of the strike rod 22 penetrates the second fixing plate 21. The shaped turntable 19 is attached to the surface of the strike rod 22. A bottom plate 37 is fixedly connected to the bottom of the mixing silo 1. A support plate 23 is fixedly connected to the top of the bottom plate 37. A sealing shell 24 is fixedly connected to the top of the support plate 23. A fan 25 is mounted on the surface of the support plate 23. A first helical gear 26 is connected to the surface of the fan 25 via a rotating rod. A second helical gear 27 is meshed with the surface of the first helical gear 26. A second transmission rod 28 is fixedly connected to the surface of the second helical gear 27. The sealing shell 24 is connected to the surface of the second transmission rod 28 via a bearing. A third helical gear 29 is fixedly connected to the other end of the second transmission rod 28. A fourth helical gear 30 is meshed with the surface of the third helical gear 29. A first transmission rod 24 is fixedly connected to the bottom of the fourth helical gear 30. A connecting pipe 32 is fixedly connected to the top of the moving rod 18 and the sealing shell 24. The other end of the connecting pipe 32 is equipped with a collection box 33. A filter device 34 is installed on the surface of the collection box 33. The material collection frame 20 fixedly connected to the bin cover 2 can prevent the raw materials from scattering and causing waste during feeding. At the same time as the second gear 12 rotates, the second gear 12 drives the second transmission rod 28 to rotate through the transmission wheel and transmission belt 17. At this time, the irregular turntable 19 on the second transmission rod 28 rotates. Under the interaction of the irregular turntable and the compression spring connected to the impact rod 22 and the second fixed plate 21, the impact rod 22 reciprocates, causing it to continuously hit the bottom of the collection box, so that the color bleach powder is discharged. The material slides down the inclined collection frame 20 into the collection box 35, facilitating the collection of fallen color bleach powder. Simultaneously, as the first transmission rod 18 rotates, the fourth helical gear 30 at the top of the first transmission rod 18 drives the transmission structure composed of the third helical gear 29, the second transmission rod 28, and the second helical gear 27. Then, through the meshing connection of the second helical gear 27, the fan 25 at the bottom of the first helical gear 26 rotates. Thus, during material feeding, the dust from the color bleach powder is not scattered and wasted; instead, it is drawn into the collection box 33 through the connecting pipe 32 by the suction of the fan 25. Under the action of the filter device 34, it is stored in the collection box 33, preventing waste.

[0029] A brush 9 is fixedly connected to the inside of the scraper 8. A screen 3 is attached to the surface of the brush 9. The brush 9 inside the scraper 8 can scrape the raw material in the holes and put it into the mixing chamber 1 for mixing, thus preventing blockage.

[0030] A third fixing plate 31 is connected to the surface of the first transmission rod 18 via a bearing. A support plate 23 is fixedly connected to the surface of the third fixing plate 31. The third fixing plate 31 prevents the first transmission rod 18 from shaking during rotation, thereby increasing the stability of the device.

[0031] A support frame 38 is fixedly connected to the bottom of the base plate 37. A baffle 39 is fixedly connected to the outside of the support frame 38. The baffle 39 on the outside of the support frame 38 can prevent the mixed raw materials from being blown away by external factors when collecting them, and can also prevent a large part of the dust from scattering, keeping it inside the baffle 39 to protect the environment.

[0032] A rubber sleeve 40 is fixedly connected to the surface of the swaying plate 10, and a bin cover 2 is bonded to the surface of the rubber sleeve 40. The rubber sleeve 40 ensures that the connection gap between the swaying plate 10 and the bin cover 2 is sealed, preventing the color bleach powder material from overflowing during the stirring process and increasing the sealing performance of the device.

[0033] Combination Figures 1-7 The specific operation of the color bleaching powder raw material mixing device with bleaching function in this embodiment is as follows: When the color bleaching powder raw material is put into the mixing device, the raw material first enters the screen 3. When the motor 4 is started, the crushing wheel in the screen 3 will rotate and crush the lumps of color bleaching powder raw material under the rotation of the stirring rod 5. Then, the scraper 8 in the screen 3 will scoop up the crushed raw material to prevent it from being crushed and blocked. At the same time, the brush 9 inside the scraper 8 can scrape the raw material in the holes and put it into the mixing chamber 1 for mixing. While the motor 4 is rotating, the first gear 11 on the stirring rod 5 will drive the second gear 12 to rotate. The push rod 13 connected to the second gear 12 through the rotating shaft will make an eccentric movement, driving the push rod 13 to make a back-and-forth movement, thereby causing the movable sleeve 14 to slide on the fixed rod 15 and hit the shaking plate 10 that penetrates the chamber cover 2 on the screen 3, causing the screen 3 to vibrate, which makes it easier for the crushed raw material to fall into the mixing chamber 1, greatly increasing the mixing efficiency.

[0034] In this embodiment, when color bleach powder is added before or during mixing, the powder may accidentally scatter outside the feed inlet, resulting in a significant amount of dust being released. This has an environmental impact and is difficult to collect. Therefore, please refer to [the relevant documentation / reference needed]. Figures 1-7In this embodiment, the collection frame 20 fixedly connected to the bin cover 2 can prevent raw materials from scattering and causing waste during feeding. Simultaneously, as the second gear 12 rotates, it drives the second transmission rod 28 to rotate via the transmission wheel and transmission belt 17. At this time, the irregularly shaped turntable 19 on the second transmission rod 28 rotates. The interaction between the rotating turntable and the compression spring connecting the impact rod 22 and the second fixed plate 21 causes the impact rod 22 to reciprocate, continuously striking the bottom of the collection box. This allows the color bleach powder raw material to slide down the inclined collection frame 20 into the collection box 35. This facilitates the collection of fallen color bleach powder. Simultaneously, as the first transmission rod 18 rotates, the fourth helical gear 30 at the top of the first transmission rod 18 drives the transmission structure composed of the third helical gear 29, the second transmission rod 28, and the second helical gear 27. Then, through the meshing connection of the second helical gear 27, the fan 25 at the bottom of the first helical gear 26 rotates. Thus, during material feeding, the dust from the color bleach powder is not scattered and wasted; instead, it is drawn into the collection box 33 through the connecting pipe 32 by the suction of the fan 25. Under the action of the filter device 34, it is stored in the collection box 33, preventing waste.

[0035] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
