[0002] Brake pads are one of the most important components in the vehicle braking system. Existing automobile brake pads are mainly composed of mounting steel plates, heat-insulating and damping rubber layers, and friction brake pads. Friction brake pads are the friction materials in automobile brake pads. There are many types of raw material components of friction materials in brake pads, which generally contain various powders, granular materials of various particle sizes, and different types of fibers. Existing large-scale automatic batching and mixing systems often have complex structures and configurations, high requirements for production sites, and expensive equipment costs. Therefore, our company has independently developed a small brake pad powder mixer based on its own needs. Summary of the invention

[0003] The purpose of the present invention is to provide a small brake pad powder mixer to address the defects of the existing automatic batching and mixing systems, such as complex structure and configuration, large floor space and high cost. The mixer comprises a mixing tank and a feed hood, a feed hopper, an inclined slide, a winding mechanism and a bag dust removal device arranged around the mixing tank. When in use, the feed hopper can be moved up along the inclined slide and the feed hopper can be unloaded into the mixing tank by winding up the wire rope through the winding mechanism. The cooperation of the feed hood and the bag dust removal device can effectively reduce dust during the feeding and mixing process. The mixer has the advantages of simple structure, easy operation, low cost, less dust during operation and good working environment.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] A brake pad powder mixer comprises a mixing tank, a feeding port on the top of the mixing tank is provided with a feeding cover with a side opening, an inclined slideway for guiding the up and down movement of the feeding hopper is provided between the side opening of the feeding cover and the ground, a U-shaped frame is hinged on the feeding hopper, the two ends of the U-shaped frame are hinged on the two side walls of the feeding hopper through a transverse rotating shaft, the top of the U-shaped frame can only swing on the upper surface of the feeding hopper, the U-shaped frame is connected to the feeding and winding mechanism through a steel wire rope, and the steel wire rope is pulled by the feeding and winding mechanism to realize the feeding hopper The inclined slide includes straight slide rails which are arranged symmetrically with grooves facing each other. The straight slide rails are profiles with a U-shaped cross section. On the inner side of the side inlet of the feed hood, the straight slide rails only include an upper wing plate and a web plate. The upper roller of the feed hopper is slidably arranged in the groove of the straight slide rail, and the lower roller of the feed hopper is located on the upper surface of the upper wing plate of the straight slide rail. The rotating shaft of the lower roller is located below the hinged end of the U-shaped frame, and the distance between the outer ends of the rotating shafts of the two lower rollers is greater than the side opening of the feed hood, and the weight of the front side of the feed hopper is less than the weight of the rear side.

[0006] By adopting the above technical scheme, a brake pad powder mixer is provided, which includes a mixing tank and a feed cover, a feed hopper, an inclined slide and a winding mechanism arranged around the mixing tank. When in use, the feed hopper can be moved up along the inclined slide and the feed hopper can be unloaded into the mixing tank by winding the wire rope through the winding mechanism (when the feed hopper moves up to the highest position, the winding mechanism continues to pull the wire rope. Since the rotating shaft of the lower roller abuts against the two sides of the side opening, and the hinged end of the U-frame is located above the lower roller, the feed hopper will tilt when the winding mechanism continues to pull the wire rope upward to achieve unloading). The mixer has the advantages of simple structure, easy operation and low cost.

[0007] The present invention is further configured as follows: inner walls on both sides of the inlet of the feed cover are provided with arc-shaped slides which are smoothly connected to the lower wing plates of the left and right straight slide rails.

[0008] By adopting the above technical solution, an arc-shaped slide smoothly connected to the lower wing plate of the straight slide rail is arranged on the inner walls of the two side walls of the inlet on the side of the feed hood. The arc-shaped slide can guide the downward movement of the feed hopper to ensure that the feed hopper can smoothly move downward and return to its original position.

[0009] The present invention is further configured as follows: an auxiliary unloading mechanism for the feed hopper is provided on the feed cover, and when the feed hopper moves up to the highest position, the auxiliary unloading mechanism presses down the discharge port on the front side of the feed hopper to enable the feed hopper to unload into the mixing tank.

[0010] By adopting the above technical solution, an auxiliary unloading mechanism is arranged on the feed cover, which can greatly alleviate the difficulty of unloading by only using a pulling U-shaped frame of a wire rope, and can effectively extend the service life of the wire rope.

[0011] The present invention is further configured as follows: the unloading mechanism includes an even number of gears arranged on the outer side wall of the side opening of the feed hood through a rotating shaft and a rack fixed to the side wall of the feed hopper, and the even number of gears are meshed with each other; the gear located at the bottom corresponds to the rack, and the rack is rotatably installed on the rotating shaft of the lower roller, and a stopper is provided on the lower side of the rack near the lower roller, and the lower end of the stopper abuts against the upper surface of the upper wing plate of the straight slide rail; the rotating shaft of the gear located at the top passes through the side wall of the feed hood, and a pressure rod for the discharge port of the feed hopper is fixed at its end; when the feed hopper moves up to a suitable position, the rack pushes the gear to rotate, thereby driving the pressure rod to press the discharge port of the feed hopper down to discharge.

[0012] By adopting the above technical solution, a specific unloading mechanism is provided, in which the gears and the pressure rod are respectively arranged on the outside and inside of the feed cover, which realizes the pressing down unloading and effectively avoids the powder adhering to the transmission structure and causing damage to the transmission structure.

[0013] The present invention is further configured as follows: a torsion spring is provided between the rack and the rotating shaft of the lower roller, and when no external force is applied, the torsion spring causes the stopper of the rack to press tightly against the upper surface of the upper wing plate of the straight slide rail.

[0014] By adopting the above technical solution, a torsion spring is arranged between the rack and the rotating shaft of the lower roller to make the block on the rack tightly press against the upper wing plate. This design can effectively ensure that the rack is always under the gear and can effectively ensure the coordination between the rack and the gear.

[0015] The present invention is further configured as follows: a transverse connecting rod is arranged between the two straight slide rails, and the transverse connecting rod is entirely located at the lower side of the lower wing plate.

[0016] By adopting the above technical solution, a transverse connecting rod is arranged between the two straight slide rails, and the transverse connecting rod can effectively improve the structural stability of the inclined slide and effectively extend the service life of the inclined slide.

[0017] The present invention is further configured as follows: a shielding curtain is provided at the side opening of the feed cover, and the shielding curtain is composed of a plurality of transverse bars and a soft rope connecting the plurality of transverse bars.

[0018] By adopting the above technical scheme, a shielding curtain is set at the side opening of the feed hood, and the shielding curtain is composed of a number of horizontal bars connected by soft ropes. When the feed hopper moves up to the highest position for unloading, the swinging feed hopper will push the shielding curtain to move up, which not only ensures the shielding of the opposite side opening, but also makes room for the upward movement of the feed hopper. When the feed hopper moves down, the shielding curtain falls back to continue to block the opposite side opening. This design can effectively ensure that the side opening is basically in a closed state during unloading and mixing, which can further avoid dust and ensure the working environment.

[0019] The present invention is further configured as follows: a first dust removal duct is arranged on the top of the feed hood.

[0020] The present invention is further configured as follows: a stirring structure driven by a driving device on the outer side of the lower end of the mixing tank is arranged in the mixing tank, a discharge port at the bottom of the side wall of the mixing tank is provided with a discharge pipe, the lower end of the discharge pipe is connected to a material receiving cover, and a second dust removal pipe is arranged above the material receiving cover.

[0021] The present invention is further configured as follows: the first dust removal duct and the second dust removal duct are connected to the bag dust removal device through a main dust removal duct.

[0022] By adopting the above technical scheme, a first dust removal pipe is arranged on the top of the feed hood, and a second dust removal pipe is arranged above the material receiving hood. At the same time, the first dust removal pipe and the second dust removal pipe are connected to the bag dust removal device. Dust removal pipes are arranged at the feeding, mixing and receiving points, which can further avoid dust.

[0023] The main beneficial effects of the present invention are:

[0024] 1. The mixer of the present invention comprises a mixing tank and a feed cover, a feed hopper, an inclined slide and a winding mechanism arranged around the mixing tank. When in use, the feed hopper can be moved upward along the inclined slide and the feed hopper can be unloaded into the mixing tank by winding the wire rope through the winding mechanism. The mixer has the advantages of simple structure, convenient operation and low cost.

[0025] 2. The powder mixer of the present invention has an arc-shaped slide smoothly connected to the lower wing plate of the straight slide rail on the inner wall of the two side walls of the inlet of the feed cover. The arc-shaped slide can guide the downward movement of the feed hopper to ensure that the feed hopper can smoothly move downward and return to its original position.

[0026] 3. The powder mixer of the present invention is provided with an auxiliary unloading mechanism on the feed cover, which can greatly alleviate the difficulty of unloading by only using a pulling U-shaped frame of a steel wire rope, and can effectively extend the service life of the steel wire rope.

[0027] 4. The powder mixer of the present invention is provided with a torsion spring between the rack and the rotating shaft of the lower roller so that the block on the rack is tightly pressed against the upper wing plate. This design can effectively ensure that the rack is always under the gear and can effectively ensure the coordination between the rack and the gear.

[0028] 5. The powder mixer of the present invention is provided with a shielding curtain at the side opening of the feed cover, and the shielding curtain is composed of a plurality of horizontal bars connected by soft ropes.

When the feed hopper moves down, the shielding curtain falls back to continue to shield the opposite side opening. This design can effectively ensure that the side opening is basically in a closed state during unloading and stirring and mixing, which can further avoid dust and ensure the working environment.

[0039] The inclined slide 2 includes a straight slide rail 21 arranged symmetrically in the form of a groove facing each other. The straight slide rail 21 is a U-shaped profile. On the inner side of the side inlet of the feed cover 4, the straight slide rail 21 only includes an upper wing plate 211 and a web plate 212. The upper roller 14 of the feed hopper 1 is slidably arranged in the groove of the straight slide rail 21, and the lower roller 13 of the feed hopper 1 is located on the upper surface of the upper wing plate 211 of the straight slide rail 21. The inner walls on both sides of the side inlet of the feed cover 4 are provided with an arc-shaped slide 44 smoothly connected to the lower wing plates 213 of the left and right straight slide rails 21. A transverse connecting rod 22 is provided between the two straight slide rails 21, and the transverse connecting rod 22 is located on the lower side of the lower wing plate 213 as a whole. The rotating shaft of the lower roller 13 is located below the hinged end of the U-shaped frame 11, and the distance between the outer ends of the rotating shafts of the two lower rollers 13 is greater than the side opening of the feed cover 4. The weight of the front side of the feed hopper 1 is less than the weight of the rear side.

[0040] The side opening of the feed cover 4 is provided with a shielding curtain, which is composed of a plurality of transverse bars and a soft rope connecting the plurality of transverse bars. A first dust removal pipe 81 is provided on the top of the feed cover 4. A stirring structure driven by a driving device on the outer side of the lower end of the mixing tank 3 is provided in the mixing tank 3. A discharge pipe 31 is provided at the discharge port at the bottom of the side wall of the mixing tank 3. The lower end of the discharge pipe 31 is connected to the material receiving cover 5. A second dust removal pipe 82 is provided above the material receiving cover 5. The first dust removal pipe 81 and the second dust removal pipe 82 are connected to the bag dust removal device 8 through the main dust removal pipe 83.

[0041] The feed cover 4 is provided with an auxiliary unloading mechanism for the feed hopper 1 . When the feed hopper 1 moves up to the highest position, the auxiliary unloading mechanism presses down the discharge port on the front side of the feed hopper 1 to enable the feed hopper 1 to discharge into the mixing tank 3 . The unloading mechanism includes an even number of gears 41 arranged on the outer side wall of the opening on the side of the feed cover 4 through a rotating shaft 42 and a rack 16 fixed to the side wall of the feed hopper 1, and the even number of gears 41 are meshed with each other; the gear 41 located at the bottom corresponds to the rack 16, and the rack 16 is rotatably installed on the rotating shaft of the lower roller 13, and a stopper 15 is provided on the lower side of the rack 16 near the lower roller 13, and the lower end of the stopper 15 abuts against the upper surface of the upper wing plate 211 of the straight slide rail 21; the rotating shaft 42 of the gear 41 located at the top passes through the side wall of the feed cover 4, and a pressure rod 43 for the discharge port of the feed hopper 1 is fixed at its end; when the feed hopper 1 moves up to a suitable position, the rack 16 pushes the gear 41 to rotate, thereby driving the pressure rod 43 to press the discharge port of the feed hopper 1 down to discharge.

Without the application of external force, the torsion spring causes the stopper 15 of the rack 16 to press tightly against the upper surface of the upper wing plate 211 of the straight slide rail 21 .

[0042] How it works:

[0043] Put a variety of powders into the feed hopper 1 in proportion, start the feeding and winding mechanism 6, and the feeding and winding mechanism 6 pulls the wire rope 61 to move the feed hopper 1 upward. When the feed hopper 1 moves to the top, the outer ends of the rotating shafts of the lower rollers 13 on the left and right sides of the feed hopper 1 abut against the two sides of the opening on the side of the feed cover 4, and the lower rollers 13 of the feed hopper 1 no longer move upward. At this time, the feeding and winding mechanism 6 continues to pull up the wire rope 61, and the U-shaped frame 11 above the lower roller 13 will drive the front side of the feed hopper 1 to tilt downward until the feed hopper 1 completes unloading.

[0044] When the feed hopper 1 moves up to the top of the inclined slide 2, in addition to the U-shaped frame 11 driving the feed hopper 1 to tilt forward to discharge, the rack 16 cooperates with the gears 41 on both sides of the feed cover 4, and also causes the pressure rod 43 to press Figure 5 As shown in the figure, the front side of the feed hopper 1 is pressed down by swinging counterclockwise to assist in unloading.

[0045] After unloading is completed, since the weight of the rear side of the feed hopper 1 is greater than the weight of the front side, as the feeding and winding mechanism 6 releases the wire rope 61, the feed hopper 1 returns to the inclined slide 2 along the arc slide 44 under the action of its own weight until it slides down to the ground, completing the return of the feed hopper 1.
