DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] The first preset state of the material of the present invention is a state in which the first positioning portion 71 is located below the material, and the second preset state is a state in which the first positioning portion 71 is located below the material and the first positioning portion is located in the front side of the material conveying direction, that is, the material in the second preset state is the material in which the first positioning portion is located in the front side of the material conveying direction in the first preset state.

[0028] The present invention provides a material turning mechanism for turning the material to a first preset state, please refer to Figures 1 to 5 , wherein the material has a first positioning portion 71, the first positioning portion 71 in the first preset state is located at the bottom of the material and the first positioning portion 71 is located at the front side of the material conveying direction, and the material turning mechanism includes: a driving component, the driving component is used to drive the material to move; a first steering component 41, the first steering component 41 is connected to the driving component to rotate the first positioning portion 71 of the material to the bottom of the material under the drive of the driving component; a second steering component 42, the second steering component 42 is connected to the driving component to rotate the first positioning portion 71 of the material to the front side of the material conveying direction under the drive of the driving component.

[0029] The material turning mechanism of the present invention is mainly used for adjusting the position of the material. The material turning mechanism of the present invention mainly includes a first steering assembly 41 and a second steering assembly 42, which respectively turn the material. The first steering assembly 41 is used to rotate the side of the material having the first positioning portion 71 to the bottom of the material, and the second steering assembly 42 is used to rotate the end having the first positioning portion 71 to the front side of the material conveying direction, so that the material is adjusted to the first preset state after passing through the first steering assembly 41 and the second steering assembly 42, thereby increasing the amount of material in the first preset state and improving the feeding quantity and efficiency of the feeding device.

[0030] The first steering assembly 41 includes: a steering plate 43, which is drivingly connected to the driving assembly so as to drive the material to move; and a guide bar 411, which is connected to the steering plate 43 so as to move the material along the guide direction of the guide bar 411 and rotate the first positioning portion 71 of the material to the bottom of the material. The guide bar 411 is arranged on one side of the steering plate 43, and the steering plate 43 is arranged at a predetermined angle with the horizontal plane so as to move the material along the side close to the guide bar 411 and rotate under the guidance of the guide bar 411.

[0031] The first steering assembly 41 in this embodiment includes an inclined steering plate 43 and an arc-shaped guide bar with a certain curvature. The steering plate 43 is inclined toward the inside so that the material moves to the inside of the steering plate 43 under the drive of the driving assembly and moves forward along the inside of the steering plate 43. The guide bar 411 is arranged on the inside of the steering plate 43. The guide bar 411 is an arc-shaped bar, which bends and extends along the conveying direction of the material so that the material moves along the guiding direction of the guide bar 411 and rotates under the guidance of the guide bar 411 until the first positioning portion 71 is rotated to the bottom of the material.

[0032] The material has a second positioning portion 72, and the second positioning portion 72 and the first positioning portion 71 are respectively arranged at opposite ends of the material, and the second steering assembly 42 includes: a steering groove 421, and the steering groove 421 is arranged on the steering plate 43, so as to be connected with the second positioning portion 72 of the material; wherein, when the material moves to the steering groove 421, the second positioning portion 72 of the material is inserted into the steering groove 421, until the first positioning portion 71 rotates to the front side of the material conveying direction, and the second positioning portion 72 is separated from the steering groove 421. The material turning mechanism also includes: a second blowing assembly 44, and the second blowing assembly 44 is arranged on the side of the steering plate 43 opposite to the steering groove 421, so as to blow the second positioning portion 72 of the material into the steering groove 421.

[0033] The material in this embodiment also includes a second steering component 42, and a steering groove 421 is provided on one side of the second steering component 42. The material moves forward to the position of the steering groove 421, and the second blowing component 44 blows air from the side opposite to the steering groove 421 to blow the material toward the steering groove, so that the second positioning part is inserted into the steering groove, and then the material continues to move forward. At this time, the material away from the steering groove side moves faster and the material close to the steering groove side moves slower, so that the material is turned during the forward movement, until the first positioning part rotates to the front side, the material continues to move forward to separate the second positioning part from the steering groove, completing the turning of the material.

[0034] The present invention also provides a feeding device, including a tipping mechanism 40, which is the tipping mechanism mentioned above. The feeding device also includes: a silo 10, which is connected to a driving assembly and contains materials; a feeding mechanism 20, which is connected to the driving assembly and is used to move the materials in the silo 10 to the tipping mechanism 40. The feeding device also includes: a dividing mechanism 30, which is connected to the feeding mechanism 20, and is used to divide the materials in the feeding mechanism 20 into materials in a first preset state and materials in a non-first preset state, and move the materials in a non-first preset state to the tipping mechanism 40 for rotation.

[0035] In order to improve efficiency, the feeding device in this embodiment includes a loading mechanism 20 and a dividing mechanism 30. The loading mechanism is used to transfer the material in the silo to the dividing mechanism 30. The dividing mechanism 30 is provided with a material clamping groove, which is clamped and connected with the first positioning part of the material in the first preset state. Since the dividing mechanism is arranged at an angle, the material in a state not in the first preset state moves to the inner side of the dividing mechanism, and then moves along the inner side of the dividing mechanism to the guide bar. After the dividing mechanism separates the materials, it can effectively prevent the materials from clumping, so that the turning mechanism can turn over the materials in a state not in the first preset state, thereby improving work efficiency.

[0036] The material dividing mechanism in the present invention has a guide groove 31 and a first material channel 32. The first material channel 32 is arranged at an angle so that materials in a state other than the first preset state can slide into the inner side of the first material channel. The materials in the first preset state are connected to the guide groove 31 through the first positioning portion and move along the guide groove without sliding into the inner side of the first material channel, thereby distinguishing the materials above which the first positioning portion is located and the materials below which the first positioning portion is located.

[0037] The feeding device further includes: a screening mechanism 50, which is connected to the material turning mechanism 40, and is used to screen the materials that are not in the first preset state after passing through the material turning mechanism 40; and a feeding part 60, which is connected to the screening mechanism 50, and is used to output the materials in the first preset state. The screening mechanism 50 includes: a second material channel 51, and the second material channel 51 is used to transport the materials in the first preset state to the feeding part 60.

[0038] The feeding device in this embodiment also includes a screening mechanism 50, which is arranged between the turning mechanism and the feeding part, so as to screen out the materials that have not been adjusted to the preset position by the turning mechanism, so that all the materials output by the feeding part are in the first preset state, so that the feeding device provides a large amount of materials with reliable quality. Specifically, the second material channel 51 includes: a second guide groove 511, the material is connected to the second guide groove 511 through the first positioning part 71, so that the material moves along the guiding direction of the second guide groove 511; the second material channel 51 includes a discharge port 512, and the first air outlet and the discharge port 512 are respectively arranged on the opposite sides of the second guide groove 511, so that the wind blown out from the first air outlet can blow the materials on the second material channel 51 that are not in the first preset state out from the discharge port 512.

[0039] The screening mechanism in this embodiment includes a first screening section and a second screening section. The first screening section is tilted and provided with a material holding groove. When the material in the first preset state passes through the first screening section, the first positioning portion 71 is stuck in the material holding groove and moves forward, while the material whose first positioning portion 71 is located above the material cannot be stuck in the material holding groove, and thus slides to the inner side of the first screening section under the action of tilting. An opening is provided on the inner side of the first screening section, so that the material slides out from the opening and enters the silo. The material whose first positioning portion is located at the lower side continues to move forward to the second screening section. The second screening section is provided with a first blowing assembly 52, and the first blowing assembly includes two air outlets, one blowing outward and the other blowing material from top to bottom. When the first positioning portion 71 is located at the front side of the material, the material can pass normally along the second guide groove 511, and when the first positioning portion 71 is located at the rear end of the material, the first blowing assembly 52 will cause the material to fall out from the discharge port and then fall into the silo, thereby realizing the screening of materials that are not in the first preset state.

[0040] The screening mechanism 50 includes: a third material channel 53, which is connected to the second material channel 51 and has a discharge port 512; a third blowing assembly 54, which is arranged above the third material channel 53 to blow air toward the material on the third material channel 53 and drive the material to move along the conveying direction; and a first blowing assembly 52, which is arranged on one side of the third material channel 53 to blow out the material that is not in the second preset state from the discharge port 512 by blowing air onto the third material channel 53.

[0041] The screening mechanism 50 in this embodiment includes a third material channel 53 and a first blowing assembly arranged on one side of the third material channel 53 and a third blowing assembly 54 arranged above the third material channel 53. The third blowing assembly 54 is arranged above the third material channel, and blows the material downward and in the feeding direction at the same time. The third material channel 53 is also provided with an air outlet 532 and a first baffle plate 534. The air outlet 532 is opposite to the air outlet position of the third blowing assembly 54, so that the gas blown out by the third blowing assembly 54 is blown out from the air outlet, thereby preventing the gas from running around on the third material channel and interfering with the movement of the material. When the third blowing assembly 54 blows air to the material that is not in the second predetermined state, The second positioning portion 72 of the material faces forward, and the third blowing component 54 first blows the second positioning portion of the material downward. The second positioning portion is on the upper part of the material. The third blowing component 54 blows the second positioning portion first. At this time, one side of the first positioning portion of the material that is not in the second predetermined state is tilted upward, and then the first blowing component 52 blows the tilted material to blow the material out from the discharge port 512. For the material in the second predetermined state, the third blowing component 54 first blows the first positioning portion 71, and at this time the first positioning portion 71 is in contact with the third material channel, and the second positioning portion 72 is close to the first baffle plate 534, so the material will not tilt. The third blowing component 54 blows the material to accelerate the removal of the material from the conveying direction.

[0042] The screening mechanism 50 includes: a third material channel 53, which is connected to the second material channel 51 and has a discharge port 512; a fourth blowing assembly 55, which is arranged at the bottom of the third material channel 53 and has a blowing port 531, so that the fourth blowing assembly 55 blows toward the material through the blowing port 531 to blow up the material in the second preset state; and a first blowing assembly 52, which is arranged on one side of the third material channel 53 to blow the material in the second preset state out from the discharge port 512 by blowing air toward the third material channel 53.

[0043] The screening mechanism in this embodiment includes a third material channel 53 and a first blowing assembly arranged on one side of the third material channel and a fourth blowing assembly arranged below the third material channel. The fourth blowing assembly blows air obliquely upward through the blowing port 531. When the material in the second preset state passes through, the first positioning portion is in front, and the first positioning portion moves along the third material channel and is closer to the blowing port, so that it is blown up by the gas blown by the fourth blowing assembly. After the material is tilted up, the first blowing assembly blows the material down the third material channel from one side, thereby blowing the material in the second preset state out of the third material channel. When the material at the front side passes through the third material channel, the second positioning portion is above the material, has no contact with the third material channel, and has a certain distance therefrom. Therefore, the wind force at the air outlet of the fourth blowing component is greatly reduced, and the material will not be blown. In addition, a second material baffle plate 535 is arranged above the third material channel. The material baffle plate is arranged above the blowing port. When the second positioning portion in the second preset state blows air, the second material baffle plate 535 can block the material from tilting up, thereby preventing the material from being blown away by the first blowing component. Therefore, only the material not in the second preset state is left on the third material channel, and the material in the second preset state is blown away.

[0044] The third material channel in this embodiment is further provided with a third guide groove 533. When passing through the third material channel, the first positioning portion 71 of the material moves along the third guide groove 533. The air outlet 532 or the air blowing port 531 is disposed in the third guide groove.

[0045] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0046] The driving assembly of the material turning mechanism of the present invention adopts a vibration plate, which is connected to the entire feeding device to drive the material to move by vibration. The vibration plate vibrates the material in the silo to the feeding mechanism, and then the vibration plate disperses the material stacked on the feeding mechanism.

[0047] The material of the present invention includes a first positioning portion 71 and a second positioning portion 72. The first positioning portion 71 is located at the bottom of the material and protrudes from the bottom surface of the material. The second positioning portion 72 is located above the material. The first positioning portion 71 and the second positioning portion 72 are located at two opposite positions of the material. When the material is in the first preset state, the first positioning portion 71 of the material is located below the material and the first positioning portion 71 is located at the front side of the material conveying direction. When the material is loaded, under the vibration of the vibration plate, the front side of the material on the loading mechanism with the second positioning portion 72 faces upward, and the first positioning portion 71 at the bottom of the material is gradually stuck in the guide groove 31 of the loading mechanism, and moves along the extension direction of the guide groove 31 under the vibration of the vibration plate. If the material of the present invention is reversed, since there is no protruding part at the bottom of the material when the side with the second positioning portion 72 faces downward, it cannot enter the guide groove 31.

[0048] When the material channel of the present invention is tilted inward and has the second positioning portion 72 facing downward, the material is drawn into the inside, and a material baffle plate is provided on the inside of the material channel. The material moves along the material baffle plate and slides to the position of the material turning mechanism. The guide bar 411 of the first steering assembly on the material turning mechanism has a certain curvature, which prompts the material to turn over, thereby turning over the material facing downward.

[0049] The material continues to move to the second steering assembly. A steering groove 421 is provided on the inner side of the steering plate 43 of the second steering assembly. The height position of the steering groove 421 matches the height of the second positioning portion 72 on the material, so that the second positioning portion 72 of the material facing upward is inserted into the steering groove 421. Then the material continues to move along the steering plate 43. At this time, the second positioning portion 72 is located in the steering groove 421, which will slow down the movement of one side of the second positioning portion 72 of the material and make the other side move faster, so that the material rotates, so that the side with the first positioning portion 71 rotates to the front side of the material. Then the material continues to move to separate the second positioning portion 72 from the steering groove 421, thereby achieving the purpose of the material having one side of the first positioning portion 71 facing forward, solving the problem of sorting the material in the forward and reverse directions, so that the material can be fed in the specified direction.

[0050] The feeding device of the present invention solves the problem of small material discharge quantity through the above-mentioned setting. Compared with the prior art, this scheme greatly improves the material discharge quantity.

[0051] The feeding device of the present invention solves the problem of material backflow. The backflow material can be eliminated after the vibration plate is sorted.
