Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0032] By Figures 1-10 The present application discloses an equipment for manufacturing friction plate, comprising a shell 1, a fixed frame 2 is arranged below the shell 1,

[0034] The side of the fixed frame 2 is located in the track, and the fixed frame 2 can slide along the track 2, a push rod 4 is further fixedly connected to the side of the fixed frame 2, and a fixed blanking pipe 5 is fixedly connected to the fixed frame 2, the lower end of the fixed blanking pipe 5 is sleeved with a movable blanking pipe 6, and the upper end of the fixed blanking pipe 5 can slide below the through hole, so that the material in the cavity can enter into the fixed blanking pipe 5 and the movable blanking pipe 6,

[0035] The movable blanking pipe 6 can move up and down, and an opening and closing structure is arranged at the lower end of the movable blanking pipe 6, which can gradually open when the movable blanking pipe 6 moves downward, so that the material falls down.

[0036] In the implementation of the device, the user fills the material into the shell 1, and through the use of the spiral blanking piece 9, the powder in the shell 1 can fall into the fixed blanking pipe 5, and the control of the rotation of the spiral blanking piece 9 can control the amount of blanking; then the fixed blanking pipe 5 is moved above the mold, the movable blanking pipe 6 is extended into the mold, and the material falls down, thereby realizing the operation of feeding.

[0037] Afterwards, the fixed blanking pipe 5 and the movable blanking pipe 6 are reset, so as to complete a feeding cycle, and the above operation is repeated, so that the automatic reciprocating feeding is realized, and the structure can be provided with multiple groups in application, so as to adapt to the operation of feeding multiple materials.

[0038] The fixed blanking pipe 5 and the movable blanking pipe 6 form a blanking structure, and the blanking structure has multiple groups, and each small blanking structure is provided with a spiral blanking piece 9, a driving motor 3 is fixedly connected to one side of the shell 1, a chain wheel 8 is fixedly connected to the output end of the driving motor 3 and the upper end of the spiral blanking piece 9, and a chain 7 is arranged outside the chain wheel 8, that is, when the driving motor 3 operates, the spiral blanking piece 9 can convey the materials in the shell 1 downwards and into the fixed blanking pipe 5. The surface of the spiral blanking piece 9 has a spiral plate, so that the material conveying can be realized.

[0039] In order to make the movable blanking pipe 6 move downwards, the following technical scheme is provided: a fixed seat 13 is fixedly connected to the outside of the fixed blanking pipe 5, the lower end surface of the fixed seat 13 is connected to the upper end surface of the movable blanking pipe 6 through a second spring 22, a push rod 14 is arranged to penetrate the fixed seat 13, the lower end of the push rod 14 is in abutment with the upper end surface of the movable blanking pipe 6, a rotating gear 16 capable of rotating is arranged in the fixed seat 13, a rack 19 is arranged on the surface of the push rod 14, the rotating gear 16 and the rack 19 are matched with each other, and a first steel wire 15 is further wound outside the rotating gear 16, so that when the first steel wire 15 is pulled, the rotating gear 16 can drive the push rod 14 to move downwards.

[0040] The opening and closing structure comprises the movable flap 12 and the elastic rubber ring 19, the elastic rubber ring 19 is a conical structure with large upper end and small lower end, the lower end of the elastic rubber ring 19 can be closed under the action of its elasticity, the upper end of the elastic rubber ring 19 is connected to the lower end of the movable blanking pipe 6, the movable flap 12 has two and is arranged outside the elastic rubber ring 19, and the second steel wire 18 is connected between the lower end of the fixed seat 13 and the outer wall of the movable flap 12, so that when the movable blanking pipe 6 moves downwards, the second steel wire 18 can pull the lower end of the movable flap 12 apart and open the lower end of the elastic rubber ring 19.

[0041] When the movable blanking pipe 6 moves downwards initially, the second steel wire 18 can be gradually tightened, and when the movable blanking pipe 6 is lowered to a predetermined height, that is, when it is inserted into the mold, the second steel wire 18 can pull the movable flap 12, so that the lower ends of the two movable flaps 12 are separated from each other, and the lower end of the elastic rubber ring 19 is opened, so that the materials can fall down.

[0042] The surface of the push rod 14 is provided with a protrusion 20, the inside of the fixed seat 13 is provided with a groove 21, the fixed blanking pipe 5 is further provided with a poking piece 17, the poking piece 17 is elastic, one end of the poking piece 17 is fixedly connected with the fixed blanking pipe 5, the other end of the poking piece 17 is fixedly connected with a knocking block 23, the poking piece 17 and the outer wall of the fixed blanking pipe 5 have a gap, the push rod 14 passes through the gap, the fixed blanking pipe 5 is made of iron material, and the knocking block 23 is made of magnetic material.

[0043] Since the raw material of the friction plate is mostly powder, it may be blocked and cannot fall normally when falling in the pipe. In the scheme, the protrusion 20 cooperates with the groove to form a short impact effect when the push rod 14 moves downward, thereby ensuring that the material in the movable blanking pipe 6 can fall normally. The protrusion 20 can also lift the poking piece 17 upward, so that when the protrusion 20 and the poking piece 17 are separated, the knocking block 23 can quickly combine with the fixed blanking pipe 5 under the action of magnetic force, thereby forming a knocking effect, and thereby achieving the purpose of shaking the material in the fixed blanking pipe 5.

[0044] When the protrusion 20 enters the fixed seat 13, the protrusion and the fixed seat 13 are extruded to increase the friction force. When the protrusion 20 enters the groove 21 and the protrusion and the fixed seat 13 are separated, the friction force instantaneously decreases. At this time, the first steel wire 15 can make the push rod 14 instantaneously increase the moving speed, thereby forming an impact effect.

[0045] The housing 1 is further provided with a mounting frame 24, the end of the push rod 4 away from the fixed frame 2 passes through the mounting frame 24, the end of the first steel wire 15 away from the fixed seat 13 is fixedly connected in the mounting frame 24, the first transmission gear 25 is arranged outside the push rod 4, the lead screw 27 is arranged in the mounting frame 24, the third transmission gear 28 is fixedly connected outside the lead screw 27, the first transmission gear 25 and the third transmission gear 28 are connected and transmitted through the second transmission gear 26, the first transmission gear 25 is in threaded cooperation with the push rod 4, the sliding seat 29 is arranged in threaded cooperation outside the lead screw 27, and the surface of the sliding seat 29 can press the surface of the first steel wire 15.

[0046] The first transmission gear 25 is driven by the motor, when the motor is running, the first transmission gear 25 rotates, and the first transmission gear 25 is threadedly connected with the push rod 4, so that the push rod 4 can move forward, and then the fixed frame 2 is pushed forward, until the movable blanking pipe 6 moves above the mold. When the push rod 4 moves forward, the screw rod 27 can also rotate, so that the sliding seat 29 slides forward, and at this time, the first steel wire 15 slides out of the mounting frame 24, so that in the initial stage of the mounting frame 24 sliding forward, the fixed frame 2 moves forward with the fixed blanking pipe 5 and the movable blanking pipe 6, and when the fixed frame 2 moves to the predetermined position, the first steel wire 15 can provide a pulling force, at this time the movable blanking pipe 6 can be elongated downward, so as to ensure that the material falls into the mold.

[0047] The lower end of the shell 1 is provided with a slide, and the upper end of the fixed blanking pipe 5 is located in the slide. A baffle 10 is arranged in the slide, one end of the baffle 10 extends into the slide, and the baffle 10 is connected with the side wall of the slide through the first spring 11.

[0048] The spiral blanking piece 9 can achieve the effect that the material cannot fall when it is not rotating to a certain extent, but in order to further ensure that the material will not fall, the baffle 10 structure is arranged, that is, when the fixed blanking pipe 5 moves to one side of the through hole, the baffle 10 can block the through hole under the action of the first spring 11; when the fixed blanking pipe 5 moves below the through hole, the fixed blanking pipe 5 can push the baffle 10 to open the through hole.

[0049] As shown in Figure 9 The slide has a plurality of through holes, and each fixed blanking pipe 5 is inserted into one of the slides. The upper end and the middle part of the fixed blanking pipe 5 are connected by a smooth inclined surface. The fixed blanking pipe 5 at the middle position is a vertical structure, and the fixed blanking pipe 5 at both sides has an inclined surface structure, so as to ensure that the fixed frame 2 will not interfere with each other when it is pushed.

[0050] As shown in Figure 10 The number of the slide is one, and the height of the upper end of the fixed blanking pipe 5 decreases in turn, that is, as shown in the figure, the moving direction of the fixed frame 2 is to the left, and each fixed blanking pipe 5 can fall into the material. In this embodiment, a plurality of fixed blanking pipes 5 can be arranged on the same size shell 1.
