Description

Technical Field

[0001] The utility model relates to the technical field of brake pad processing, in particular to a raw material mixing device for processing automobile brake pads. Background Art

[0002] Automobile brake pads, also known as automobile brake leathers, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction pads bear external pressure, generating friction to achieve the purpose of vehicle deceleration.

[0003] In the prior art, raw materials need to be mixed during the production process of automobile brake pads, and thus a raw material mixing device is required. The existing mixing devices basically use a motor to drive a stirring rod to rotate in a stirring barrel, and then the raw materials poured into the mixing device are mixed and stirred. However, during stirring, the raw materials at the bottom of the stirring barrel are difficult to mix evenly, which easily causes uneven mixing and affects the subsequent processing of the brake pads. Therefore, there is room for improvement. Utility Model Content

[0004] The utility model provides a raw material mixing device for processing automobile brake pads, so as to solve the problems raised in the background technology.

[0005] In order to solve the above problems, the present invention provides a raw material mixing device for processing automobile brake pads, including a stirring barrel, the stirring barrel is bucket-shaped and has a discharge port at the bottom, a conveying cylinder is provided at the axis center of the stirring barrel, and the bottom of the conveying cylinder is connected to the bottom of the stirring barrel, a rotating shaft is provided in the stirring barrel, and the rotating shaft passes through the bottom of the conveying cylinder and is located in the discharge port, the top end of the rotating shaft is connected to a forward and reverse motor, and the forward and reverse motor is provided at the top of the stirring barrel, the rotating shaft is located at the end of the conveying cylinder with a first spiral conveying blade, and a transverse rod is fixedly provided at the upper part of the conveying cylinder in the rotating shaft, and a vertical downward stirring rod is fixedly provided at each end of the transverse rod.

[0006] Preferably, a feeding pipe is provided on the top of the mixing barrel on one side of the forward and reverse motors, and the bottom end of the feeding pipe is located below the top of the conveying cylinder.

[0007] Preferably, a second spiral conveying blade is fixedly provided at the end of the rotating shaft located at the discharge port.

[0008] Preferably, a downwardly inclined material guide plate is provided around the top of the conveying cylinder.

[0009] The beneficial effects of adopting the above technical solution are:

[0010] 1. The conveying cylinder cooperates with the first spiral conveying blade and the second spiral conveying blade to transport the raw materials at the bottom of the mixing barrel to the top, and then cooperates with the stirring rod to stir, so that the raw materials in the mixing barrel are stirred and mixed more evenly.

[0011] 2. After the raw materials in the mixing barrel are mixed, the motor is reversed to drive the rotating shaft to drive the first spiral conveying blade and the second spiral conveying blade to rotate, so as to quickly discharge the raw materials in the mixing barrel to avoid blockage of the discharge port and improve the discharge efficiency.

[0018] like Figure 1-2In this embodiment, a raw material mixing device for processing automobile brake pads includes a mixing barrel 1. The mixing barrel 1 is bucket-shaped and has a discharge port 11 at the bottom. A conveying cylinder 2 is provided at the axis center of the mixing barrel 1, and the bottom of the conveying cylinder 2 is connected to the bottom of the mixing barrel 1. A rotating shaft 3 is provided in the mixing barrel 1, and the rotating shaft 3 passes through the bottom of the conveying cylinder 2 and is located in the discharge port 11. The top of the rotating shaft 3 is connected to a forward and reverse motor 4, and the forward and reverse motor 4 is provided at the top of the mixing barrel 1. The end of the rotating shaft 3 located in the conveying cylinder 2 is provided with a first spiral conveying blade 31. A transverse rod 32 is fixedly provided on the upper part of the rotating shaft 3 located on the conveying cylinder 2, and a vertical downward stirring rod 33 is fixedly provided at each end of the transverse rod 32.

[0019] Through the above technical solution, when in use, the raw materials are first fed into the mixing barrel 1, and the forward and reverse motor 4 drives the rotating shaft 3 to rotate forward, so that the raw materials at the bottom of the mixing barrel 1 can be fed into the top of the mixing barrel 1 through the first spiral conveying blade 31 and the conveying cylinder 2, and then the stirring rods 33 on both sides are driven to rotate by the transverse rod 32, so that the raw materials in the mixing barrel are mixed more evenly, and the mixing effect is improved. When unloading, the forward and reverse motor 4 drives the rotating shaft 3 to reverse, so that the first spiral conveying blade 31 quickly discharges the raw materials in the conveying cylinder 2, which is convenient for the raw materials to be discharged from the unloading port 11, thereby improving the unloading efficiency.

[0020] Preferably, a feeding pipe 12 is provided on the top of the mixing barrel 1 on one side of the forward and reverse motor 4, and the bottom end of the feeding pipe 12 is located below the top of the conveying cylinder 2.

[0022] Preferably, a second spiral conveying blade 34 is fixedly provided at the end of the rotating shaft 3 located at the discharge port 11 .

[0023] Through the above technical solution, the second spiral conveying blade 34 is set to transport the raw materials in the discharge port 11 back to the mixing barrel 1 when the forward and reverse motor 4 is running forward, thereby improving the mixing effect. When discharging, the forward and reverse motor 4 is reversed to avoid blockage of the raw materials at the discharge port 11 when discharging, thereby improving the discharge efficiency.

[0024] Preferably, a downwardly inclined material guide plate 21 is provided around the top of the conveying cylinder 2 .

[0025] Through the above technical solution, the setting of the guide plate 21 can evenly guide the raw materials conveyed in the conveying cylinder 2 into the mixing barrel 1 from the top of the conveying cylinder 2, thereby improving the uniformity of subsequent mixing.
