Description

Technical Field

[0002] Brake pads are key components used to slow down or stop the rotation of wheels in vehicles such as automobiles. They are usually made of materials with a high friction coefficient to ensure that sufficient friction can be generated quickly during braking to stop the vehicle safely.

[0003] In the process of brake pad manufacturing, in order to obtain ideal friction performance and wear resistance, it is often necessary to mix a variety of raw materials. These raw materials may include different types of resins, fibers, graphite, metal particles, etc. Their proportion and uniformity have a crucial impact on the final performance of the brake pad. Therefore, mixing is an important process in the manufacturing process of brake pads.

[0004] However, the existing brake pad mixing equipment has some obvious disadvantages. Since the brake pad is a material with a high friction coefficient, high temperature is easily generated during the mixing process, and high temperature will cause the organic components in the material to decompose, reducing the friction coefficient, that is, thermal decay. In addition, high temperature will accelerate the wear of the mixing blades and the mixing shaft, reducing the service life of the equipment.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-Figure 15The embodiment of the present invention provides a technical solution: comprising a mounting bracket 1 and a mixing tank body 4, the mounting bracket 1 is also provided with a driving motor 2, and a mixing shaft 21 penetrating into the mixing tank body 4 is provided on the power output end of the driving motor 2, and a plurality of groups of mixing blades 22 are evenly spaced on the outer surface of the mixing shaft 21. When the brake pad material needs to be mixed, the brake pad material to be mixed needs to be put into the mixing box first, and then the driving motor 2 is started to rotate the mixing shaft 21 and the mixing blades 22 to achieve mixing of the brake pad material in the mixing box. The mixing tank body 4 is characterized in that the mixing tank body 4 is a hollow structure as a whole and has openings integrally formed at both ends, and the two opening positions of the mixing tank body 4 are provided with mixing blades. The temporary storage box 41 is connected to the internal space of the tank body 4, and two opening and closing plates 9 are arranged at the positions of the two temporary storage boxes 41 near the opening of the mixing tank body 4 through the damping shaft 10. The brake pad manufacturing ingredient mixing equipment also includes: when the mixing tank body 4 with a hollow interior and both ends in an open state mixes the brake material, the temporary storage boxes 41 at both ends can alternately temporarily store the brake material in the mixing tank body 4 to prevent the temperature of the brake material from continuing to rise due to the increase of friction during the mixing process, to prevent the organic components in the brake pad material from decomposing, resulting in a decrease in the friction coefficient, that is, to prevent the occurrence of thermal attenuation, and to prevent the reduction of the service life of the mixing blade 22 or the mixing shaft 21 at high temperature; The rotating frame 42 arranged on the mounting bracket 1 is rotated by the reinforcing shaft 43, and the mixing tank body 4 and the temporary storage box body 41 are both arranged on the rotating frame 42; the rotating frame 42 is arranged so that the mixing tank body 4 and the temporary storage box body 41 can be rotated as a whole, so that the brake pad material in the mixing tank body 4 can enter the temporary storage box body 41 located below under the action of gravity, and the brake pad material in the mixing box body located above can enter the mixing box body, so that the brake pad material can alternately enter the mixing box body for mixing, and at the same time, the brake pad material can alternately enter the temporary storage box body 41 for cooling, so as to prevent the occurrence of a temperature at which the material performance is reduced due to the increase in the temperature of the brake pad material and the mixing blade 22; An intermittent feeding mechanism, which is connected to the driving motor 2 through a driving mechanism, and is also provided with a push plate 62 through the intermittent feeding mechanism. When the driving motor 2 is started to mix the brake pad material in the mixing tank 4, the push plate 62 is continuously and intermittently moved upward through the intermittent feeding mechanism; The conversion assembly is arranged on the mounting bracket 1 and connects the driving motor 2 with the rotating frame 42. When the push plate 62 rises to abut against the conversion assembly, the conversion assembly is used to rotate the rotating frame 42, the mixing tank body 4 and the temporary storage box 41 as a whole; when the driving motor 2 continuously drives the mixing shaft 21 and the mixing blades 22 to continuously mix the brake materials in the mixing tank body 4, the intermittent feeding mechanism can continuously move the push plate 62 upward, but the upward movement of the push plate 62 can be small each time, until the driving motor 2 continues to run for a period of time, the push plate 62 is abutted against the conversion assembly, at which time the mixing tank body 4 and the rotating frame 42 are rotated as a whole through the conversion assembly; A reset mechanism is arranged on the mounting bracket 1 and connected to the reinforcing shaft 43. After the mixing tank body 4 rotates half a circle, the reset mechanism is used to reset the push plate 62, and at the same time, the mixing tank body 4 is stopped by the conversion component; after the mixing tank body 4 rotates half a circle, the push plate 62 is automatically reset by the reset mechanism, and at the same time, the mixing tank body 4 is stopped by the conversion component. After the mixing tank body 4 rotates to the position of the two temporary storage boxes 41 being exchanged, the rotation is automatically stopped, so that the brake material in the mixing tank body 4 at this time enters the temporary storage box 41 located below for temporary storage under the action of gravity, and the brake material in the temporary storage box 41 located above at this time enters the mixing box for mixing, so as to realize the alternating mixing of the brake materials and prevent the overheating of the brake materials. The whole process is carried out automatically without manual control, and the overall operation is relatively convenient. The opening and closing mechanism is arranged between the damping shaft 10 and the mounting bracket 1. When the mixing tank body 4 and the temporary storage box rotate as a whole, the opening and closing mechanism is used to open and then close the opening and closing plate 9 of the temporary storage box body 41 located below, and after the opening and closing plate 9 is closed, the opening and closing plate 9 of the temporary storage box body 41 located above is opened, and when the next rotation of the temporary storage box body 41 starts, the opening and closing plate 9 of the temporary storage box body 41 located above is closed. When the mixing tank body 4 and the two temporary storage boxes 41 rotate as a whole, the opening and closing mechanism will first open the opening and closing plate 9 on the temporary storage box 41 located at the bottom, so that the brake material in the mixing tank body 4 enters the temporary storage box 41 located at the bottom, and then when the temporary storage box 41 and the mixing tank body 4 are about to rotate to the stop position, the opening and closing mechanism will first close the opening and closing plate 9 of the temporary storage box located at the bottom, which is now filled with the brake material, and then from this time to the process of the mixing tank body 4 and the temporary storage box 41 stopping their rotation, the opening and closing mechanism will open the opening and closing plate 9 of the temporary storage box 41 located at the top, so that the brake material therein enters the mixing tank body 4, and then After that, when the mixing tank 4 and the temporary storage box 41 rotate as a whole next time, the opening and closing mechanism will be used to close the opening and closing plate 9 on the temporary storage box 41 located at the top of the mixing tank, so that the brake material in the mixing tank 4 can be discharged into the temporary storage box 41 located at the bottom first, and the opening and closing plate 9 of the temporary storage box 41 is closed, and then the opening and closing plate 9 of the temporary storage box 41 located at the top will be opened, so that the brake material after cooling therein enters the mixing box, so that the brake materials in the two temporary storage boxes 41 will not be cross-mixed, and the brake materials in the two temporary storage boxes 41 will not be cross-mixed in large quantities, which will affect the mixing and cooling effects. The intermittent feeding mechanism includes multiple groups of slide rails 6 fixedly arranged on the mounting bracket 1 and a half gear 61 rotatably arranged on the mounting bracket 1 and connected to the driving mechanism. Two gears 67 are rotatably arranged on the surface of the mounting bracket 1 on both sides of the half gear 61, and the two gears 67 are meshed with the half gear 61. A slotted lifting plate 64 is slidably arranged in each group of slide rails 6, and multiple slotted lifting plates 64 are fixedly arranged with each other. Among them, the number of slide rails 6 is preferably four groups, and the four groups of slide rails 6 are rectangular as a whole in top view. Eccentric wheels 66 are fixedly arranged on the two gears 67. A slider 68 is installed at the eccentric position of the eccentric wheel 66 through a crank 65, and the slider 68 is slidably arranged in a limiting track 63. The limiting track 63 is arranged on the mounting bracket 1. A lifting push rod 69 with one side end abutting against the notch surface of the slotted lifting plate 64 is rotatably arranged on the slider 68 through a torsion spring, and the push plate 62 is fixedly arranged on multiple slotted lifting plates 64.

[0022] It should be noted that when the drive motor 2 is in the starting state, the half gear 61 is driven to rotate through the driving mechanism, and when the half gear 61 rotates, the two gears 67 are rotated intermittently and alternately. When one of the gears 67 rotates, the eccentric wheel 66 thereon is rotated through the crank 65 to make the slider 68 reciprocate up and down in the limit track 63, thereby causing the lifting push rod 69 to reciprocate up and down, while the other gear 67 does not rotate at this time, and the eccentric wheel 66, crank 65 and slider 68 thereon do not move, so that the lifting push rod 69 on the gear 67 that does not rotate at this time abuts against the groove on the slotted lifting plate 64. The surface of the opening is used as a support, and the lifting push rod 69 on the rotating gear 1 67 reciprocates up and down with the crank 65 and the slider 68. When descending, the torsion spring is deformed, and the lifting push rod 69 engages with the notch of the slotted lifting plate 64. When ascending, due to the action of the torsion spring, the lifting push rod 69 abuts against the notch of the slotted lifting plate 64, driving the slotted lifting plate 64 to rise in the slide rail 6. Then, due to the continuous operation of the driving motor 2, the half gear 61 rotates to another half circle, so that the movement states of the two gears 1 67 are opposite, and they reciprocate in turn, realizing the intermittent and continuous rise of the slotted lifting plate 64, so that the push plate 62 rises continuously step by step; It should be noted that, in one embodiment of the present invention, the driving mechanism includes a driving wheel 31, wherein the driving wheel 31 is rotatably arranged on the mounting bracket 1, and a synchronous belt 3 is installed between the driving wheel 31 and the power output shaft of the driving motor 2 through a synchronous wheel, and the half gear 61 is connected to the driving wheel 31. When the driving motor 2 is started, the driving wheel 31 and the half gear 61 are rotated through the synchronous belt 3. It should be noted that in order to meet the mixing requirements of the brake material in the mixing tank 4, an effective deceleration effect can be formed by changing the radius ratio between the synchronous wheel and the driving wheel 31 on the driving motor 2. For example, the half gear 61 rotates one circle for every ten rotations of the power shaft of the driving motor 2, thereby delaying the rising time of the push plate 62. The same effect can also be achieved by using a deceleration mechanism, such as various types of gearboxes, reduction gears, etc., which are all prior art and will not be described in detail here. It should also be noted that when the eccentric wheel 66 rotates one circle, that is, when the lifting push rod 69 forms a complete up and down reciprocating motion, the depth of the lifting push rod 69 in the downward movement will not exceed the gap between each slot of the slotted lifting plate 64, that is, when the lifting push rod 69 rises after descending, it will only push the adjacent slots on the slotted lifting plate 64. This can be achieved by changing the position of the crank 65 on the eccentric wheel 66. The closer the crank 65 is to the circle of the eccentric wheel 66, the shorter the reciprocating motion distance of the slider 68 and the lifting push rod 69 in each rotation. This is also a prior art and will not be repeated. The connection between the half gear 61 and the mounting bracket 1 is also provided with a damper to prevent the problem that the slotted lifting plate 64 pushes the lifting push rod 69 in the opposite direction to rotate the eccentric wheel 66 when the teeth on the half gear 61 are separated from the gear 1 67. The damper makes the gear 1 67 and the eccentric wheel 66 have a self-locking effect. The damper is a prior art product and will not be described in detail. The conversion assembly rotates the inner gear ring 52 set on the mounting bracket 1 and the sun gear plate 53 set on the output shaft of the driving motor 2, and a planetary gear set 51 is set between the inner gear ring 52 and the gear plate, and the planetary gear set 51 is meshed with the inner gear ring 52 and the sun gear plate 53 at the same time, and a planet carrier 5 is set on the planetary gear set 51, and the planet carrier 5 is connected to the rotating frame 42. By changing the movement of the inner gear ring 52 and the planet carrier 5, the movement of the rotating frame 42 can be changed. In one case, the planet carrier 5 is in a fixed state, then when the driving motor 2 drives the sun gear plate 53 to rotate In the case of the planetary gear set 51 and the inner gear ring 52 rotating, the planetary carrier 5 does not rotate. In the other case, the inner gear ring 52 is fixed. At this time, when the driving motor 2 drives the sun gear plate 53 to rotate, the planetary carrier 5 as a whole will revolve around the sun gear plate 53, while the inner gear ring 52 is fixed. When the planetary carrier 5 is locked, the rotating frame 42 will not rotate. When the planetary carrier 5 is contact-locked and the inner gear ring 52 is locked, the driving motor 2 continues to work, and the rotating frame 42 and the mixing tank body 4 and the temporary storage box body 41 on the rotating frame 42 are rotated as a whole through the planetary carrier 5. The conversion assembly also includes an adjustment mechanism disposed on the mounting bracket 1, and the adjustment mechanism is used to lock the planetary carrier 5. When the lifting push plate 62 rises to a position and abuts against the adjustment mechanism, the adjustment mechanism is used to unlock the planetary carrier 5 and lock the inner gear ring 52 at the same time. In the initial state, that is, when the rotating frame 42 and the mixing tank body 4 and the temporary storage box body 41 on the rotating frame 42 do not need to rotate, the adjustment mechanism locks the planetary carrier 5 but does not lock the inner gear ring 52. At this time, the inner gear ring 52 rotates, and the planetary carrier 5 will not drive the rotating frame 42 to rotate. When the push plate 62 rises to a certain height and abuts against the adjustment mechanism, the adjustment mechanism will change the locking method of the inner gear ring 52 and the planetary carrier 5. At this time, the inner gear ring 52 is locked, and the planetary carrier 5 is unlocked. At this time, when the drive motor 2 is working, This will cause the planet carrier 5 to revolve around the sun gear plate 53, thereby causing the rotating frame 42 to rotate; after the driving motor 2 has been working for a period of time, as the push plate 62 gradually rises, the push plate 62 and the adjusting mechanism will abut against each other, which can automatically cause the rotating frame 42 and the mixing tank body 4 and the temporary storage box body 41 to rotate as a whole, thereby changing the position of the brake materials in the mixing tank body 4 and the two temporary storage boxes 41. Without manual operation, the mixing tank body 4 and the temporary storage box body 41 rotate periodically and automatically, thereby improving the convenience of the overall operation.

[0023] The adjustment mechanism includes a frame body 57 mounted on the mounting bracket 1 through a torsion spring, and a driving belt 56 mounted on the frame body 57. The belt surfaces on both sides of the driving belt 56 are respectively provided with a resistance block 1 54 and a resistance block 2 55 through elastic members, wherein the resistance block 2 55 resists against the surface of the planetary carrier 5, and a resistance block 3 58 is fixedly provided on the surface of the belt on the side of the driving belt 56 close to the resistance block 1 54. When the push plate 62 gradually rises, the pressure plate resists against the surface of the resistance block 3 58. After starting the driving motor 2 and mixing the brake raw materials in the mixing box for a period of time through the mixing shaft 21 and the mixing blades 22, the push plate 62 is gradually raised through the intermittent feeding mechanism until the push plate 62 abuts against the surface of the friction block three 58. At this time, when the push plate 62 rises again, it will push the friction block three 58 upward to make the driving belt 56 rotate on the frame 57. At this time, the friction block one 54 moves upward to abut against the surface of the inner gear ring 52. At the same time, the friction block two 55 moves downward to separate from the planetary frame 5. At this time, the lock on the planetary frame 5 is released and the inner gear ring 52 is fixed. At this time, driven by the sun gear disc 53, the planetary frame 5 drives the rotating frame 42 and the mixing tank body 4 and the temporary storage box body 41 on the rotating frame 42 to rotate, wherein the elastic member can be a spring column or a hydraulic column, which is the prior art and will not be repeated here.

[0024] The reset mechanism includes a long shaft 7 slidably arranged on the mounting bracket 1 and a cam 71 rotatably arranged on the mounting bracket 1. A synchronous belt 72 is installed between the end of the cam 71 and the reinforcing shaft 43 via a synchronous wheel. When the rotating frame 42 rotates as a whole, the reinforcing shaft 43 will also be in a rotating state, and the cam 71 will rotate through the synchronous belt 72. It should be noted here that if Figure 2 and Figure 3As shown, the initial position of the cam 71 is located on the right side of the long axis 7. When the rotating frame 42 rotates half a circle and the positions of the two temporary storage boxes 41 thereon are swapped, the cam 71 just rotates one circle. This can be achieved by adjusting the radius ratio of the reinforcing shaft 43 and the synchronous wheel on the cam 71. This is a prior art and the details are not repeated here. When the raised portion of the cam 71 rotates to abut against the long axis 7, the long axis 7 moves upward on the mounting bracket 1 and abuts against the lifting push rod 69 to deform the torsion spring on the lifting push rod 69. After the lifting push rod 69 is deflected, it is separated from the notch on the slotted lifting plate 64. At this time, the slotted lifting plate 64 quickly falls to the initial position under the action of gravity. At this time, the mixing tank body 4 is about to be in a state of flipping half a circle. Under the action of gravity, it will maintain the current motion state until the two temporary storage boxes 41 are in a vertical direction. At this time, the cam The wheel 71 just rotates a full circle and returns to its original position, so that the long shaft 7 is separated from the lifting push rod 69. At this time, under the action of the torsion spring, the lifting push rod 69 returns to its original position. It should be noted that in order to make the slotted lifting plate 64 fall to the lowest point on the slide rail 6 under the action of gravity without being damaged, an elastic part can be provided between the slide rail 6 and the slotted lifting plate 64. The elastic part can be soft rubber or a spring. It is a prior art and will not be described here. After the slotted lifting plate 64 drops to the initial position, when the torsion spring recovers its deformation, in order to enable the lifting push rod 69 to be inserted into the notch on the slotted lifting plate 64, the position of the uppermost notch of the slotted lifting plate 64 must be within the reciprocating range of the lifting push rod 69 to ensure that the lifting push rod 69 can lift the slotted lifting plate 64 here in subsequent use. It should also be noted that in order to improve the locking effect of the planetary carrier 5 on the abutment block 2 55, the abutment block 2 55 and the abutment block 1 54 are all made of materials with a large friction coefficient with the planetary carrier 5 and the inner gear ring 52 to increase friction and thus improve the locking effect, or a slot is provided on the surface of the planetary carrier 5. After the abutment block 2 55 is inserted into the slot on the planetary carrier 5, the planetary carrier 5 can be locked, and the position of the slot can be set up or down, that is, it can be provided on the two outer surfaces of the perpendicular position of the circular position of the planetary carrier 5 and the inner gear ring 52. In this way, each time the mixing tank body 4 and the rotating frame 42 rotate half a circle, the mixing tank body 4 will remain in a vertical state under the action of gravity. In this way, after the push plate 62 is separated from the abutment block 3 58, the drive belt 56 on the frame body 57 returns to its original position under the action of the torsion spring, and the abutment block 2 55 will contact the surface of the planetary carrier 5 again. At this time, due to the mixing tank body 4 and the rotating frame 42 rotate half a circle, so that the slot of the planetary frame 5 also rotates half a circle, and the friction block 2 55 can be inserted into the slot, and the friction block 1 54 is separated from the inner ring gear 52 at this time, and the lock of the inner ring gear 52 is released. At this time, the planetary frame 5 and the rotating frame 42 no longer rotate, and in order to allow the friction block 2 55 to be smoothly inserted into the slot on the planetary frame 5, the slot can be slightly larger than the size of the friction block 2 55. Since the temporary storage box 41 located below is full of brake pad materials at this time, the overall center of gravity is low, and the mixing tank body 4 is not easy to rotate, the slot slightly larger than the friction block 2 55 does not affect the overall use, and the setting of the elastic members on the friction blocks 2 55 and the friction blocks 1 54, when the friction blocks 2 55 and the friction blocks 1 54 are respectively against the surfaces of the planetary frame 5 and the inner ring gear 52, the deformation of the elastic members will undoubtedly increase the positive pressure, thereby increasing the friction, so as to improve the locking effect.

[0025] The opening and closing mechanism includes an annular slide groove 82 provided on the mounting bracket 1, the annular slide groove 82 is divided into an inner ring surface and an outer ring surface, an inner tooth group 1 8 and an inner tooth group 2 81 are provided on the inner ring surface and the outer ring surface of the annular slide groove 82, and the opening and closing mechanism also includes an opening and closing part, when the temporary storage box 41 rotates to below the horizontal center line of the annular slide rail 6, the opening and closing part cooperates with the inner tooth group 2 81 to open and then close the opening and closing plate 9 of the temporary storage box 41 located below, so that the brake material in the mixing tank 4 can enter the temporary storage box 41 located below under the action of gravity, and the brake material in the mixing tank 4 can enter the temporary storage box 41 located below under the action of gravity. After the brake material inside enters into the temporary storage box 41 located below and the opening and closing plate 9 of the temporary storage box 41 located below is closed under the cooperation of the opening and closing part and the inner gear group 81, the opening and closing plate 9 of the temporary storage box 41 located above begins to open under the cooperation of the opening and closing part and the inner gear group 8, so that the brake material in the cooled temporary storage box 41 located above enters into the mixing box under the action of gravity for mixing, preventing the two batches of materials from mixing with each other, and staggering the opening and closing of the opening and closing plates 9 on the two temporary storage boxes 41 to prevent affecting the mixing and cooling effect.

[0026] The opening and closing part includes two gear threes 85 which are rotatably arranged on the inner wall surface of the temporary storage box 41 and mesh with each other. The two gear threes 85 are respectively connected to the damping shafts 10 on the two opening and closing plates 9, and one of the gear threes 85 is provided with a gear two 83 which is slidably connected to the surface of the annular groove through a connecting rod 84.

[0027] It should be noted that when the two temporary storage boxes 41 rotate with the mixing tank 4 and the rotating frame 42, the connecting rod 84 will also cause the gear 2 83 to rotate in the annular groove 82, and the gear 2 83 on the temporary storage box 41 below the rotation will mesh with the inner gear set 2 81. Since the teeth on the inner gear set 2 81 are also segmented on the inner and outer surfaces of the annular groove 82, please refer to Fig.12 , which will cause the gear 2 83 on the temporary storage box 41 located below to rotate clockwise first and then counterclockwise. When the gear 2 83 rotates clockwise, one of the gears 3 85 rotates clockwise through the connecting rod 84, and the other gear 3 85 meshing with it rotates clockwise, thereby opening the opening and closing plate 9 through the damping shaft 10. At this time, the brake material in the mixing tank 4 enters the temporary storage box 41 located below under the action of gravity, and then the gear 2 83 meshes with the other section of the inner gear set 2 81, so that the gear 2 83 rotates in the opposite direction, thereby closing the opening and closing plate 9 on the temporary storage box 41 located below. At this time, when the positions of the two temporary storage boxes 41 are completely reversed, the gear 2 83 on the upper temporary storage box 41 meshes with the front section of the inner gear set 1 8. At this time, the gear 2 83 on the upper temporary storage box 41 meshes with the front section of the inner gear set 1 8. 3 rotates, so that the opening and closing plate 9 on the upper temporary storage box 41 is opened, and the brake material that has been cooled in the upper temporary storage box 41 enters the mixing box for mixing. It is not until the next rotation of the temporary storage box 41 that the upper part is closed, so that the opening and closing plate 9 on the lower temporary storage box 41 is first opened and then closed before the opening and closing plate 9 on the upper temporary storage box 41 is opened, so as to prevent the two waves of materials from mixing with each other. When the brake material is mixed, the mixed material can be alternately entered into the temporary storage box 41 for cooling, so as to prevent the problem of excessive temperature of the brake material or damage to the material or the mixing blade 22 caused by continuous mixing. When the mixing tank 4 is turned over, it can also promote the mixing of the brake material, and further improve the use effect.

[0028] The mixing shaft 21 and the mixing blades 22 are made of wear-resistant material, which can improve the heat resistance of the mixing blades 22 and the mixing shaft 21 and increase their service life.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
