Description

Technical Field

The invention relates to the technical field of material sorting, in particular to a material conveying mechanism and a sorting device.

Background

Before the sorting device carries out sorting work, the materials need to be conveyed to the sorting mechanism, and when the sorting mechanism is observed, the sorting mechanism judges whether the materials need to be removed.

However, when some materials have large elasticity, such as flexible plastic particles and rubber, are fed to the guide plate through the hopper, the materials are easy to bounce and fall on the guide plate due to the large elasticity of the materials, so that the motion tracks of the materials are not straight lines, the materials are easy to fall without looking points, the identification is inaccurate, and the materials fall without looking points and are easy to be rejected inaccurately, so that the precision of material separation is low.

In view of the above, it is important to develop a material conveying mechanism and a sorting device capable of solving the above technical problems.

Example (b):

referring to fig. 1, fig. 1 is a schematic structural diagram of a material conveying mechanism 10 applied to a sorting apparatus 100 according to an embodiment of the present invention.

The embodiment of the invention provides a material conveying mechanism 10, the material conveying mechanism 10 has the characteristic that the conveying of materials 900 is stable, and particularly for the materials 900 which are easy to bounce, the material conveying mechanism 10 can reduce the bounce amplitude of the materials 900 in conveying and improve the conveying stability. The material transfer mechanism 10 can be applied to the sorting apparatus 100 and other material 900 processing apparatuses, and the material transfer mechanism 10 can be used independently. When the material conveying mechanism 10 is applied to the sorting device 100, the sorting device 100 conveys the material 900 to the sorting mechanism 20 of the sorting device 100 through the material conveying mechanism 10, so as to improve the sorting accuracy when the sorting device 100 sorts the easily bounceable material 900. Since the sorting device 100 adopts the material conveying mechanism 10 provided by the embodiment of the invention, the sorting device 100 also has the characteristic that the conveying of the material 900 is relatively stable.

The structural composition, the working principle and the beneficial effects of the material conveying mechanism 10 provided by the embodiment of the present invention will be specifically described below.

Referring to fig. 1, the material conveying mechanism 10 includes a feeding hopper 11, a guide plate 12 and a first electrostatic generator 13. The first electrostatic generator 13 is electrically connected to the feeding hopper 11 and is used for enabling the feeding hopper 11 to enable the feeding hopper 11 to electrostatically adsorb the material 900 in the feeding hopper, so that the material 900 slowly falls to the guide plate 12, and the bouncing amplitude of the material 900 after falling to the guide plate 12 is reduced. The guide plate 12 is a metal plate and is disposed close to the discharge port 111 of the feeding hopper 11, and the guide plate 12 is used for guiding the falling material 900 from the discharge port 111 to the sorting mechanism 20 of the sorting device 100, so that the sorting mechanism 20 can sort the falling material 900, and thus, the material 900 in the feeding hopper 11 is charged with electricity and carries a certain charge, and after the material 900 falls from the discharge port 111, the guide plate 12 and the charged material 900 can be adsorbed, thereby further reducing the bouncing amplitude of the material 900 after falling to the guide plate 12, further stably guiding the material 900 to the sorting mechanism 20, and achieving the purpose of stably conveying the material 900.

It should be noted that the guide plate 12 extends from the discharge port 111 to the sorting mechanism 20 to convey the material 900 to the sorting mechanism 20. In addition, in this embodiment, a vibrator 14 is further installed on the feeding hopper 11, and the vibrator 14 can drive the feeding hopper 11 to vibrate, so that the charged material 900 falls onto the flow guide plate 12 through the discharging opening 111.

Further, the material conveying mechanism 10 may further include a second electrostatic generator 15, where the second electrostatic generator 15 is disposed near the flow guide plate 12 and is configured to generate an electric field, so that the material 900 reaching the flow guide plate 12 can have a tendency of moving towards the flow guide plate 12 under the action of the electric field, in other words, the second electrostatic generator 15 can generate an electric field at the position of the flow guide plate 12, and the electric field can cause the material 900 therein to have a tendency of moving towards the flow guide plate 12, thereby further reducing the amplitude of thick bounce of the material 900 falling to the flow guide plate 12, and further improving the stability of the material conveying mechanism 10 in conveying the material 900.

It should be noted that, in this embodiment, the second electrostatic generator 15 may be electrically connected to the flow guide plate 12, so as to generate an electric field through the flow guide plate 12, so that the flow guide plate 12 adsorbs the material 900, and the bounce amplitude of the material 900 is reduced. Also, second electrostatic generator 15 may charge deflector 12 opposite to falling material 900, such that deflector 12 may attract charged material 900 before charged material 900 contacts deflector 12, to more evenly fall material 900 onto deflector 12.

In addition, the connection position of the second electrostatic generator 15 on the flow guide plate 12 may correspond to the discharge port 111, so that the position where the material 900 falls and contacts the flow guide plate 12 has a larger adsorption force, and thus the material 900 is strongly adsorbed by the falling position of the material 900 on the flow guide plate 12, and the bouncing amplitude of the material 900 on the flow guide plate 12 is further reduced.

In addition, in other embodiments, the surface of the flow guiding plate 12 may also be covered with an insulating membrane to insulate the material 900 falling through the discharge hole 111 from the flow guiding plate 12 by the insulating membrane, and the second electrostatic generator 15 is electrically connected to the flow guiding plate 12 to generate an electric field through the flow guiding plate 12, so that the falling material 900 maintains an electric charge by adding the insulating membrane to maintain the adsorption of the material 900 by the flow guiding plate 12 during the falling along the flow guiding plate 12, thereby continuously adsorbing the material 900, and continuously reducing the bouncing amplitude of the material 900 on the flow guiding plate 12 during the falling of the flow guiding plate 12. At this time, of course, the connection position of the guide plate 12 and the second electrostatic generator 15 may also correspond to the discharge hole 111, so as to maintain a larger adsorption force at the position where the material 900 contacts the guide plate 12 after falling down.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a material conveying mechanism 10 having a first electrostatic plate 16 and applied to a sorting apparatus 100 according to an embodiment of the present invention.

Further, the material conveying mechanism 10 may further include a first electrostatic plate 16, the first electrostatic plate 16 extends along a side of the diversion plate 12 away from the discharge hole 111, and a space is provided between the first electrostatic plate 16 and the diversion plate 12, the second electrostatic generator 15 is electrically connected to the first electrostatic plate 16, and an electric field is generated by the first electrostatic plate 16, in other words, the electric field generated by the first electrostatic plate 16 extends along the diversion plate 12, and it can continuously adsorb the charged material 900 by the electric field having a certain length, so as to improve an effect of reducing a bounce amplitude of the material 900.

It should be noted that first electrostatic plate 16 may also extend from the top end of baffle 12 to the bottom end of baffle 12. Thus, after the material 900 falls to the guide plate 12, until the material 900 is separated from the guide plate 12, the material 900 always has a tendency of moving towards the guide plate 12 under the action of the electric field, so as to further improve the effect of reducing the bounce amplitude of the material 900.

Further, the material conveying mechanism 10 may further include a second electrostatic plate 17, the second electrostatic plate 17 extends along an end of the diversion plate 12 away from the first electrostatic plate 16, and a space is provided between the second electrostatic plate 17 and the diversion plate 12, and the material 900 falls down along the diversion plate 12 through the space between the second electrostatic plate 17 and the diversion plate 12, or the diversion plate 12 is located between the first electrostatic plate 16 and the second electrostatic plate 17, and the second electrostatic plate 17 is located above the diversion plate 12. The second electrostatic generator 15 is electrically connected to the second electrostatic plate 17, so that the first electrostatic plate 16 and the second electrostatic plate 17 jointly generate a stronger electric field, thereby further improving the effect of reducing the bounce amplitude of the material 900.

It should be noted that in other embodiments, the first electrostatic plate 16 may be replaced by a baffle plate 12 covered with an insulating membrane, so that the above-mentioned electric field is generated by the baffle plate 12 and the second electrostatic plate 17 together.

The working principle of the material conveying mechanism 10 provided by the embodiment of the invention is as follows:

the material conveying mechanism 10 comprises a feeding hopper 11, a guide plate 12 and a first static generator 13. The first electrostatic generator 13 is electrically connected to the feeding hopper 11 and is used for enabling the feeding hopper 11 to enable the feeding hopper 11 to electrostatically adsorb the material 900 in the feeding hopper, so that the material 900 slowly falls to the guide plate 12, and the bouncing amplitude of the material 900 after falling to the guide plate 12 is reduced. The guide plate 12 is a metal plate and is disposed close to the discharge port 111 of the feeding hopper 11, and the guide plate 12 is used for guiding the falling material 900 from the discharge port 111 to the sorting mechanism 20 of the sorting device 100, so that the sorting mechanism 20 can sort the falling material 900, and thus, the material 900 in the feeding hopper 11 is charged with electricity and carries a certain charge, and after the material 900 falls from the discharge port 111, the guide plate 12 and the charged material 900 can be adsorbed, thereby further reducing the bouncing amplitude of the material 900 after falling to the guide plate 12, further stably guiding the material 900 to the sorting mechanism 20, and achieving the purpose of stably conveying the material 900.

In summary, the following steps:

the embodiment of the invention provides a material conveying mechanism 10 which has the characteristic that the conveying of materials 900 is stable.
