Detailed Implementation

[0028] The technical solutions of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In an exemplary implementation, such as Figures 1-3 As shown, this embodiment provides a liquid silicone rubber colorant production system, which includes:

[0031] Tank 1 is vertically arranged and contains a stirring assembly. The top of the tank 1 is also equipped with a liquid inlet pipe 2 and the bottom with a material guide pipe 3.

[0032] The feeding hopper 4 is fixedly installed on the top side of the tank body 1. The lower end of the feeding hopper 4 is connected to the inside of the tank body 1. A bag-breaking top rod 5 is also raised and lowered inside the feeding hopper 4. A first umbrella-shaped plate 6 is fixedly arranged around the bag-breaking top rod 5. Several discharge ports 7 are opened on the first umbrella-shaped plate 6. A first notch 8 is also provided on the bottom surface of the first umbrella-shaped plate 6.

[0033] The first support ring 9 is fixedly connected in the feeding hopper 4, and the upper wall inner side of the first support ring 9 is further provided with a second notch 10. The lower end of the first umbrella-shaped disc 6 can abut against the first support ring 9, and when abutting, the first notch 8 and the second notch 10 enclose a first channel 11 that is in communication with the upper and lower parts of the first umbrella-shaped disc 6.

[0034] The grinding conveying pipe 12 is horizontally arranged below the material guide pipe 3 and is in communication with the lower end of the material guide pipe 3. The grinding conveying pipe 12 is further coaxially arranged with a first spiral 13 and a rotating cylinder 14 arranged outside the first spiral 13. The outer wall of the rotating cylinder 14 is further fixedly connected with a plurality of annular plates 15. The rotating cylinder 14 between adjacent annular plates 15 is further provided with a plurality of first communication holes in communication with the inside and outside of the rotating cylinder 14. The grinding conveying pipe 12 is further fixedly connected with a discharge pipe 16 in communication therewith.

[0035] In the process of feeding, the ton bag 17 filled with solid material can be lifted by the lifting mechanism (similar to the existing technology, such as a crane), so that the lower end of the ton bag 17 enters the feeding hopper 4. When the bag breaking jacking rod 5 contacts the ton bag 17, the ton bag 17 is opened by the upward jacking of the bag breaking jacking rod 5, the material falls, and then the ton bag 17 is slowly lifted by the lifting mechanism so that the material in the ton bag 17 falls into the feeding hopper 4. During the feeding process, the ton bag 17 can not be completely withdrawn above the feeding hopper 4, so that the ton bag 17 can block the accidental spatter of the material during the feeding process. The bag breaking jacking rod 5 can also continue to move up and down in the feeding hopper 4, driving the first umbrella-shaped disc 6 to move up and down, loosening and dredging the material, and avoiding blockage. More specifically, a plurality of discharge ports 7 are provided on the first umbrella-shaped disc 6, which can allow the material to pass through when the first umbrella-shaped disc 6 is stationary or moving up and down, ensuring smooth downward movement of the material. The first support ring 9 provides upward support for the first umbrella-shaped disc 6, and a first channel 11 is also provided between the first support ring 9 and the first umbrella-shaped disc 6 for the material to pass through. Further, the upper end of the tank body 1 is fixedly connected with a mounting box 18 which is in communication with the outside of the tank body 1 and extends into the tank body 1. The top surface of the mounting box 18 is fixedly connected with an arc-shaped plate 19, and the arc-shaped opening of the arc-shaped plate 19 extends upward and is fixedly connected with the inner top surface of the tank body 1 at both ends. A telescopic drive 20 is fixedly installed in the mounting box 18, and the telescopic drive 20 has an output end 21 which extends through the arc-shaped plate 19 and into the tank body 1. The output end 21 extends upward into the feeding hopper 4 and is connected with a telescopic head 22 which is telescopically arranged. The first umbrella-shaped disc 6 is fixedly connected with the telescopic head 22, and the bag breaking jacking rod 5 is fixedly connected with the telescopic head 22. The telescopic drive 20 can be a pneumatic cylinder or an oil cylinder. The lower end of the output end 21 is fixed with the arc-shaped plate 19, so that the material on the arc-shaped plate 19 cannot leak outward. At the same time, the arc-shaped plate 19 in the present scheme is inclined, specifically, the higher side is fixedly connected with the inner wall of the tank body 1, and the lower side extends towards the center of the tank body 1. In this way, an inclined arc-shaped channel is formed below the feeding hopper 4. After the material in the feeding hopper 4 enters the tank body 1, it first falls into the arc-shaped channel, and then slides downward along the arc-shaped plate 19 towards the middle of the tank body 1, and finally falls to the lower end of the tank body 1. The liquid inlet pipe 2 introduces liquid material, and the stirring assembly can be started. More specifically, the telescopic head 22 is partially located in the first umbrella-shaped disc 6, the lower end of which extends below the first umbrella-shaped disc 6 and is provided with an installation hole 23 which is smaller at the top and larger at the bottom. The installation hole 23 is coaxially arranged with the telescopic head 22, and a telescopic rod 24 is fixedly connected with the inner top surface of the installation hole 23. The telescopic rod 24 is telescopically connected with the output end 21, that is, the telescopic drive 20 drives the telescopic rod 24 to move up and down relative to the output end 21. At the same time, the end of the output end 21 is in the form of a smaller top and a larger bottom which matches the installation hole 23. When the first umbrella-shaped disc 6 is at the lowest position, the inner wall of the installation hole 23 is closest to the outer wall of the end of the output end 21.

[0036] The grinding conveying pipe 12 is further arranged below the tank body 1, the first spiral 13 and the rotating cylinder 14 in the grinding conveying pipe 12 are matched to make the material processed by the stirring assembly in the tank body 1 be stirred and sheared again, so that the overall processing efficiency can be improved, and the problems of easy blocking and low processing efficiency of a large amount of feeding at one time in the prior art are solved. Specifically, the first spiral 13 and the rotating cylinder 14 are respectively driven by the first conveying motor 25 and the second conveying motor 26 arranged at two ends of the extension conveying pipe, that is, one end of the grinding conveying pipe 12 is fixedly connected with the first conveying motor 25, the first conveying motor 25 is connected with the first spiral 13 to drive the first spiral 13 to rotate, the other end of the grinding conveying pipe 12 is fixedly connected with the second conveying motor 26, the second conveying motor 26 is further connected with the second spiral 27 which is rotatably arranged in the grinding conveying pipe 12, and the second spiral 27 is further fixedly connected with the rotating cylinder 14. Further, the first valve 28 is further arranged on the material guide pipe 3 to open and close the material guide pipe 3. When the processing starts, the material guide pipe 3 is in a closed state. After running for a period of time, the material guide pipe 3 is opened to make part of the material enter the grinding conveying pipe 12 below, and then the material guide pipe 3 is closed. The first conveying motor 25 and the second conveying motor 26 are started to make the first spiral 13 and the rotating cylinder 14 rotate. The first spiral 13 can push the material, and the annular plate 15 on the rotating cylinder 14 can also push the material. The two kinds of pushing cooperate with each other to make the materials run more fiercely with each other to achieve more sufficient stirring and shearing effect. After a period of running, the material is guided out through the discharge pipe 16. More specifically, the discharge pipe 16 in the present scheme is located below the grinding conveying pipe 12 and close to one side of the second conveying motor 26, and the second valve 29 arranged on the discharge pipe 16 is opened when discharging. Wherein, the first communication hole is arranged on the rotating cylinder 14, the material can pass through the first communication hole to run in and out of the rotating cylinder 14, and the material will also pass through the first communication hole to run in and out of the rotating cylinder 14 in the running process of the first spiral 13 and the annular plate 15. In this way, the stirring and shearing efficiency of the material can be further improved. More specifically, all the annular plates 15 are equally distributed and the outer edges thereof are rotatably matched with the inner wall of the grinding conveying pipe 12. The annular plates 15 and the grinding conveying pipe 12 are rotatably matched with each other to provide rotating support for the annular plates 15, so that the rotating cylinder 14 can run more stably, and the first spiral 13 can also be rotatably matched with the inner wall of the rotating cylinder 14. Meanwhile, in the present scheme, a plurality of second communication holes are further arranged on the annular plate 15 to communicate the spaces on both sides of the annular plate 15, so as to cooperate with the annular plate 15 and the first spiral 13 to make the stirring and shearing more intense.The first spiral 13 comprises a first driving shaft 30, and the first driving shaft 30 is also rotatably connected with the rotating cylinder 14, and the end of the first driving shaft 30 is rotatably connected with the rotating cylinder 14, so that the rotating cylinder 14 provides rotating support for the first driving shaft 30 (i.e. the first spiral 13), and indirectly makes the first spiral 13 run stably. In a specific operation scheme, the rotating directions of the first spiral 13 and the rotating cylinder 14 can be the same or opposite, and both can play a role in stirring and shearing. More specifically, the annular plate 15 in the scheme can also be inclined, which can play a role similar to a spiral structure when the rotating cylinder 14 rotates, and better push the material to move in the grinding conveying pipe 12, so as to cooperate with the first spiral 13, the second spiral 27 and the rotating cylinder 14 to achieve better stirring and shearing effect. More specifically, the second spiral 27 is similar to the first spiral 13, comprising a second driving shaft 31 connected with the second conveying motor 26, and the second driving shaft 31 is fixedly connected with one end of the rotating cylinder 14, so that the second conveying motor 26 can smoothly drive the rotating cylinder 14 to rotate through the second spiral 27. At the same time, the other end of the rotating cylinder 14 is away from the grinding conveying cylinder, so that the material can enter and exit the rotating cylinder 14 through the away place, and the rotating cylinder 14 can cooperate with the first spiral 13 more smoothly. In the scheme, the first valve 28 can also be in a continuous open state during processing, so that the grinding conveying pipe 12 and the tank body 1 are in a continuous processing system, which can also realize cooperation to make the stirring and shearing run smoothly.

[0037] As Figure 1 , 5As shown, in a further exemplary scheme, the tank body 1 is provided with a mounting shaft 32, which is vertically arranged, and an installation sleeve 33 is fixedly arranged outside the mounting shaft 32, and an agitating rod 34 is fixedly installed on the installation sleeve 33, and a stirring motor 35 is further installed on the top of the tank body 1, and the stirring motor 35 is connected with the mounting shaft 32 to drive the mounting shaft 32 to rotate, thereby driving the agitating rod 34 to rotate to realize stirring of the material in the tank body 1, and more specifically, the stirring motor 35 is connected with the mounting shaft 32 through a speed reducer 36, that is, the stirring assembly in the present scheme comprises the stirring motor 35, the mounting shaft 32 and the agitating rod 34, and meanwhile, a material returning spiral 37 is further fixedly connected with the lower end of the mounting shaft 32, and the material returning spiral 37 rotates with the mounting shaft 32, and when rotating in the forward direction or the reverse direction, the material is lifted upward or pushed downward, so as to realize better stirring and shearing of the material in cooperation with the stirring rod above; in a more specific scheme, the lower end of the tank body 1 is provided with a material collecting hopper 38, the upper end of the material guide pipe 3 is connected with the lower end of the material collecting hopper 38, and a second umbrella-shaped disc 39 is further fixedly arranged in the material collecting hopper 38 to divide the material collecting hopper 38 into upper and lower parts, a plurality of material passing holes 40 are formed in the second umbrella-shaped disc 39, the agitating rod 34 is located above the second umbrella-shaped disc 39, and the material returning spiral 37 is located below the second umbrella-shaped disc 39, so that the material needs to pass through the material passing holes 40 arranged on the second umbrella-shaped disc 39 when moving upward and downward, so as to further intensify the stirring and shearing effect; in more detail, the second umbrella-shaped disc 39 further provides rotary limiting for the lower end of the mounting shaft 32, and specifically, a rotary sleeve 41 is fixedly connected with the top of the second umbrella-shaped disc 39 and arranged outside the mounting shaft 32, and the rotary sleeve 41 provides rotary limiting for the mounting shaft 32 under the cooperation of the second umbrella-shaped disc 39, so as to avoid shaking of the lower end of the mounting shaft 32 during operation, and thus more stable rotation can be realized; the lower end of the mounting shaft 32 is further fixedly connected with an inclined strip 42 which is arranged close to the inner wall of one side of the second umbrella-shaped disc 39, so that the inclined strip 42 rotates with the mounting shaft 32, and can sequentially sweep below the material passing holes 40 in the process, so as to further intensify the stirring of the material, and meanwhile, the material can not be stranded in the material passing holes 40; in more detail, a second supporting ring 43 is further fixedly connected in the material collecting hopper 38, the lower end of the second umbrella-shaped disc 39 is fixedly connected with the second supporting ring 43, and a second channel 44 which communicates between the upper and lower parts of the second umbrella-shaped disc 39 is further arranged between the second umbrella-shaped disc 39 and the second supporting ring 43, the second supporting ring 43 provides an installation base for the second umbrella-shaped disc 39, and the second channel 44 is arranged to provide a smoother passage for the material.

[0038] As Figures 1-3As shown, in a further detailed exemplary scheme, the production system also includes a pair of vertically fixed mounting plates 45 and a horizontal plate 46 fixedly connected to the upper end of the two mounting plates 45. The feed hopper 4 is fixedly connected to the horizontal plate 46, and the horizontal plate 46 is also provided with a feed inlet 47 communicating with the upper end of the feed hopper 4. The mounting plates 45 and the horizontal plate 46 form a U-shaped mounting frame above the tank body 1. During feeding, the ton bag 17 can partially rest on the horizontal plate 46. The feeding process can be started when the lower end of the discharge is in contact with the bag-breaking top rod 5. Specifically, the telescopic driver 20 is activated, the bag-breaking top rod 5 pushes upward to break the ton bag 17, and then inserts into the ton bag 17, and then pulls downward to remove the ton bag 17. The material can then fall downward into the lower end of the feed hopper 4 and then onto the first umbrella-shaped plate 6. Material can pass through both the discharge port 7 and the first notch 8 on the disc 6. When the first umbrella-shaped disc 6 abuts against the first support ring 9, the first channel 11 can also allow material to pass through. The first umbrella-shaped disc 6 also allows the material to spread outwards. During the spreading process, some material passes through the discharge port 7, the first notch 8, or the first channel 11, while the rest leaves from the outer edge. This prevents a large amount of material from falling directly and blocking the lower end of the feed hopper 4 during the discharge process. More specifically, in this solution, the lifting range of the bag-breaking top rod 5 is not large, mainly occurring at the lower end of the feed hopper 4. During the lifting process, the first umbrella-shaped disc 6 can be partially located inside the ton bag 17. During the continuous up and down process, the distance between the first umbrella-shaped disc 6 and the lower opening of the ton bag 17 increases, decreases, or remains in the middle state (e.g., ...). Figure 2 At the lowest point Figure 3 (at the highest point), so that the material discharges at varying speeds or at a nearly constant speed, which can reduce the frequency of material blockage and thus achieve continuous feeding; in a more specific scheme, the reducer 36 can be installed on the top of the tank 1, and the stirring motor 35 can be installed on the horizontal plate 46.

[0039] like Figure 1 As shown, in a further exemplary embodiment, the two ends of the grinding conveying pipe 12 are fixedly connected to two mounting plates 45 respectively, which makes the grinding conveying pipe 12 more stable and the system has more stable overall stability.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
