[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses an adjustable ratio friction material mixing device, including a horizontally arranged mixing cylinder 1. The top of the inner cavity of the mixing cylinder 1 is axially provided with a first groove 15, and the first groove 15 is provided with a main material hole 16 and an auxiliary material hole 17. The bottom of the inner cavity of the mixing cylinder 1 is axially provided with a second groove 18, and the second groove 18 is provided with a discharge hole 19. The first groove 15 is provided with a first sealing plate 14 that blocks and seals the main material hole 16 and the auxiliary material hole 17. The second groove 18 is provided with a second sealing plate that blocks and seals the discharge hole 19. An adjustable ratio auxiliary material adding mechanism is installed on the auxiliary material hole 17. The interior of the mixing cylinder 1 is provided with multiple push plates 12 in a ring structure.
[0023] The first groove is located at the bottom of the mixing cylinder, while the raw material is located in the lower half of the inner cavity of the mixing cylinder. Therefore, after the first sealing plate is opened, the raw material will not enter the first groove.
[0024] In this embodiment, the auxiliary material adding mechanism includes an auxiliary material pipe 6, a flow sensor 7, an auxiliary material hopper 10, a rotary valve 9, and a connecting pipe 8. The auxiliary material pipe 6 is installed on the mixing cylinder 1 and is positioned opposite to the auxiliary material hole 17. The flow sensor 7 is installed at one end of the auxiliary material pipe 6. The connecting pipe 8 is installed between the flow sensor 7 and the rotary valve 9. The auxiliary material hopper 10 is installed on the feed end of the rotary valve 9. A servo motor is installed at one end of the rotary valve 9. The servo motor is controlled by a PLC controller and controls the valve's operation based on the feedback signal from the flow sensor.
[0025] In this embodiment, one end of the first groove 15 and the second groove 18 is provided with a positioning port that communicates with the outside. One end of the first sealing plate 14 and the second sealing plate extends through the positioning port to the outside and is equipped with a fixing plate 3. A cylinder 2 is installed on the outer wall surface of the mixing chamber opposite to the fixing plate 3. The piston rod of the cylinder 2 is installed on the fixing plate 3.
[0026] In this embodiment, the mixing cylinder 1 is equipped with a main material pipe 5 and a discharge pipe 4. The main material pipe 5 is arranged opposite to the main material hole 16, and the discharge pipe 4 is arranged opposite to the discharge hole 19.
[0027] In this embodiment, a stepper motor 11 is installed at one end of the mixing cylinder 1. The rotating shaft of the stepper motor 11 extends through the mixing cylinder 1 into the inner cavity. A connecting rod 13 is installed between the rotating shaft of the stepper motor 11 and the push plate 12.
[0028] In this embodiment, the vertical cross-sections of the first sealing plate 14 and the second sealing plate are both arc-shaped. The inner surfaces of the first sealing plate 14 and the second sealing plate are flush with the inner wall of the mixing cylinder 1 to ensure the flatness of the inner wall of the mixing cylinder and allow the raw materials to move smoothly in the mixing cylinder.
[0029] In this embodiment, a fixing frame is installed on the outside of the mixing cylinder 1.
[0030] When in use, pour the auxiliary materials into the auxiliary material hopper. When the main material is added, start the corresponding cylinder. The extension of the piston rod on the cylinder can drive the fixed plate and the first sealing plate, so that the first sealing plate is moved away from the main material hole, allowing the main material to be added into the mixing cylinder along the main material pipe and the main material hole. After the material is added, push the first sealing plate back and start the stepper motor. The start of the stepper motor drives the connecting rod and the push plate. The push plate can scoop up the internal material and drop it repeatedly downwards to complete the mixing of the raw materials.
[0031] In this process, when the raw materials are mixed to the middle or later stage, the cylinder corresponding to the first sealing plate is activated again, causing the first sealing plate to move outward again until the auxiliary material hole is opened. At this time, the servo motor is activated to run the rotary valve, which discharges the auxiliary material from the auxiliary material hopper. The discharge volume is constantly monitored by the flow sensor. Once the mixing ratio is reached, the servo motor is directly shut off, and the opening below the feed hopper is sealed by the rotary valve. After the auxiliary material is added, the first sealing plate is pushed back again, so that the inner wall of the mixing cylinder is always in a flat state during the mixing process, allowing the raw materials inside to flow smoothly.
[0032] After mixing is complete, the cylinder corresponding to the second sealing plate is activated, causing the second sealing plate to move outward until the discharge hole is opened, allowing the internal material to be discharged through the discharge hole.
[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
