DETAILED DESCRIPTION

[0022] In the following description, numerous specific details are set forth to provide a more thorough understanding of the present application. However, it will be apparent to one of skill in the art that the present application can be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present application.

[0023] The application discloses a rubber particle push plate feeding and discharging device, which blows the rubber particles vertically standing on the feeding mechanism to avoid the problem of low feeding efficiency caused by material jamming.

[0024] As shown in the rubber particle push plate feeding and discharging device, the device comprises a feeding mechanism 1, a top plate 2, a discharging mechanism 3 and a blowing member 4. Figure 1 The feeding mechanism 1 and the discharging mechanism 3 can be provided with sensors, and the sensors are connected with power elements and PLC control equipment to realize automatic control.

[0025] The feeding mechanism 1, the top plate 2 and the discharging mechanism 3 are sequentially arranged, and the blowing member 4 is arranged above the top plate 2.

[0026] The height of the upper surface of the top plate 2 near one end of the feeding mechanism 1 is greater than the height near the other end of the feeding mechanism 1.

[0027] The blowing member 4 is used for connecting a gas source device, and the blowing member 4 is used for blowing air from above the end of the top plate 2 near the mechanism to above the end of the top plate 2 near the feeding mechanism 1 to the vertically standing rubber particles.

[0028] In addition to blowing the rubber particles, the blowing member 4 can also make the air flow above the top plate 2 to reduce the dust falling on the top plate 2.

[0029] Regarding the feeding mechanism 1, as shown in the rubber particle push plate feeding and discharging device, the feeding mechanism 1 comprises a hopper 11, a fixed plate 12, a push plate 13 and a power element 14. Figure 1 2 The power element 14 is a gas cylinder.

[0030] A plurality of fixed plates 12 are arranged in a stepped manner between the hopper 11 and the discharging mechanism 3, one push plate 13 is arranged between every two fixed plates 12, and the power element 14 is connected with the push plate 13.

[0031] A first dust discharging hole 111 is formed in the bottom wall of the hopper 11, and the bottom end of the hopper 11 is used for connecting a vacuum device to make the first dust discharging hole 111 communicate with the vacuum device. Figure 3 A plurality of first dust discharging holes 111 are arranged in a rectangular distribution on the bottom wall of the hopper 11.​

[0032] The top end of the fixed plate 12 is provided with a second dust discharging hole 121, and the bottom end or side end of the fixed plate 12 is used to connect a vacuum device, so that the second dust discharging hole 121 is communicated with the vacuum device, as shown in the figure. Figure 1 A plurality of second dust discharging holes 121 are arranged in a “one” shape at the top end of the fixed plate 12.

[0033] The top end of the push plate 13 is provided with a chamfer structure 131 on one side close to the bin 11, as shown in the figure. Figure 1 The chamfer structure 131 is a slope structure, and the distance from the top end of the slope structure to the adjacent fixed plate 12 is less than the radius of the rubber particles, so as to reduce the probability of material jamming.

[0034] Regarding the discharging mechanism 3, as shown in the figure. Figure 1 The discharging mechanism 3 includes a discharging motor 31, a conveying belt 32, a height blocking plate 33, and a material returning channel 34.

[0035] The conveying belt 32 is arranged at the end of the top plate 2 away from the feeding mechanism 1, the discharging motor 31 is connected with the conveying belt 32, the height blocking plate 33 is arranged at one end of the conveying belt 32, and one end of the material returning channel 34 is arranged at the side of the height blocking plate 33, and the other end extends to the feeding mechanism 1, wherein the horizontal direction in which the conveying belt 32 drives the rubber particles to move is the transverse direction, and the horizontal direction parallel to the transverse direction is the longitudinal direction.

[0036] The distance between the height blocking plate 33 and the conveying belt 32 is greater than the diameter of the rubber particles, and the distance between the height blocking plate 33 and the conveying belt 32 is less than the height of the rubber particles.

[0037] As shown in the figure. Figure 1 The height blocking plate 33 is arranged at an obtuse angle with the advancing direction of the conveying belt 32, and when the vertical rubber particles move to the height blocking plate 33, they are blocked by the height blocking plate 33 and move into the material returning channel 34, and then move into the bin 11 of the feeding mechanism 1 through the material returning channel 34.

[0038] Working method: the power member 14 drives the push plate 13 to move up and down obliquely, so that the rubber particles in the bin 11 move upwards from bottom to top along the fixed plate 12 to the top plate 2.

[0039] When the rubber particles move to the top plate 2 in a vertical state, the air blowing member 4 blows the vertical rubber particles down, and the blown rubber particles fall back into the bin 11, or roll along the top plate 2 to the conveying belt 32 of the discharging mechanism 3.

[0040] When the conveying belt 32 of the discharging mechanism 3 conveys the vertical rubber particles to the position of the height blocking plate 33, the height blocking plate 33 blocks the vertical rubber particles to fall into the material returning channel 34, so that the rubber particles fall back into the bin 11 along the material returning channel 34.

[0041] When the rubber particles are on the material bin and the fixed plate, the rubber particles can be dedusted through the first dust discharging hole and the second dust discharging hole.

Various modifications in form and detail can be made without departing from the spirit and scope of the application as defined by the appended claims.
