Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] This utility model provides a material guiding and alignment mechanism for a screening machine, including a guiding device 1 for guiding materials. In addition, this utility model also includes a vertical moving device 2, a horizontal moving device 3, and a front-back moving device 4. The vertical moving device 2 is connected to the horizontal moving device 3 to drive the horizontal moving device 3 to move vertically. The horizontal moving device 3 is connected to the front-back moving device 4 to drive the front-back moving device 4 to move horizontally. The front-back moving device 4 is connected to the guiding device 1 to drive the guiding device 1 to move back and forth.
[0024] It is understood that the material guiding and straightening mechanism of this utility model is set near the material guiding mechanism of the screening machine. The material guiding mechanism is a device such as a conveyor belt used for conveying materials. The straightening device 1 is used to guide the material to ensure the material conveying effect. When it is necessary to adjust the position of the straightening device 1, the left and right moving device 3 can be driven to move up and down by the up and down moving device 2; the left and right moving device 3 can be driven to move left and right by the forward and backward moving device 4; and the forward and backward moving device 4 can be driven to move the straightening device 1 forward and backward.
[0025] In this embodiment, the up-and-down moving device 2, the left-and-right moving device 3, and the front-and-back moving device 4 can all be sliding tables. Further, the up-and-down moving device 2 specifically includes a first mounting frame 5, a first knob 6, a first lead screw 7, and a first slider 8. The first lead screw 7 is rotatably mounted on the first mounting frame 5, and the first slider 8 is slidably mounted on the first mounting frame 5. The first lead screw 7 is threadedly connected to one side of the first slider 8, and the other side of the first slider 8 is fixedly connected to the left-and-right moving device 3. The first knob 6 is located at the outer end of the first lead screw 7. It can be understood that the working principle of the up-and-down moving device 2 is as follows: rotating the first knob 6 clockwise or counterclockwise drives the first lead screw 7 to rotate, the first lead screw 7 drives the first slider 8 to slide up and down relative to the first mounting frame 5, and the first slider 8 drives the left-and-right moving device 3 to move up and down. The material guiding and straightening mechanism of this utility model can be mounted on a screening machine using the aforementioned first mounting frame 5.
[0026] The aforementioned left-right moving device 3 may specifically include a second mounting bracket 9, a second knob, a second lead screw, and a second slider. The second mounting bracket 9 is fixedly connected to the first slider 8. The second lead screw is rotatably mounted on the second mounting bracket 9. The second slider is slidably mounted on the second mounting bracket 9. The second lead screw is threadedly connected to the second slider. The second slider is fixedly connected to the front-back moving device 4. The second knob is located at the outer end of the second lead screw. Similarly, the working principle of the aforementioned left-right moving device 3 is as follows: rotating the second knob clockwise or counterclockwise drives the second lead screw to rotate. The second lead screw drives the second slider to slide left and right relative to the second mounting bracket. The second slider drives the front-back moving device to move left and right.
[0027] The aforementioned forward and backward moving device 4 may specifically include a third mounting bracket, a third knob, a third lead screw, and a third slider 13. The third mounting bracket is fixedly connected to the second slider. The third lead screw is rotatably mounted on the third mounting bracket. The third slider 13 is slidably mounted on the third mounting bracket. The third lead screw and the third slider 13 are threadedly connected. The third slider 13 is fixedly connected to the guiding device 1. The third knob is located at the outer end of the third lead screw. Similarly, the working principle of the aforementioned forward and backward moving device 4 is as follows: rotating the third knob clockwise or counterclockwise drives the third lead screw to rotate, which in turn drives the third slider 13 to slide back and forth relative to the third mounting bracket. The third slider 13 then drives the guiding device 1 to move back and forth.
[0028] In addition, in other embodiments, the up-down moving device 2, the left-right moving device 3, and the front-back moving device 4 of this utility model can also be electric slides with motor-driven lead screws, or other types of moving devices in the prior art such as cylinders. No further restrictions are imposed here.
[0029] The aforementioned guiding device 1 may specifically include an electrostatic guiding device 10. When materials rub against or come into contact with the guiding mechanism, static electricity is easily generated due to charge transfer. Static electricity can cause materials to attract and clump together, adhering to the surface of the guiding components, thus affecting the uniform conveying of materials. Furthermore, materials carrying static electricity may deviate from the preset guiding path due to the repulsion or attraction between charges. To address these issues, the electrostatic guiding device 10 eliminates the static electricity on the materials, thereby eliminating the attraction and adhesion of static electricity on the materials, preventing material deviation or bouncing, and ensuring the stability of the guiding path, thus enabling the materials to be conveyed stably and orderly. The aforementioned electrostatic guiding device 10 is prior art and will not be described in detail here.
[0030] Preferably, the electrostatic guiding device 10 includes a needle-shaped electrode. Compared with the rectangular electrode used in the prior art electrostatic guiding device, the needle-shaped electrode can make the charge release more concentrated, the neutralization efficiency higher, and the electric field coverage more precise, thereby better improving the guiding effect of the electrostatic guiding device 10.
[0031] In addition, the aforementioned guiding device 1 may also include a negative pressure guiding device 11. The negative pressure guiding device 11 typically includes components such as a vacuum generator 12 and a negative pressure adsorption port. The vacuum generator 12 can be connected to the negative pressure adsorption port via a flexible air tube. The vacuum generator 12 can be positioned on the second mounting bracket 9, the third mounting bracket, or the third slider 13, etc., and the negative pressure adsorption port is located on the third slider 13. During the material guiding process, the material may deviate from the preset path due to uneven gravity, equipment vibration, or differences in its own flowability (such as different particle sizes or powder agglomeration), resulting in some material not entering the screening area. Therefore, the negative pressure generated by the negative pressure adsorption port of the negative pressure guiding device 11 is used to regulate the material's conveying path and attitude, that is, using the suction force of the airflow to pull the material to the center of the preset path, ensuring that the material accurately and centrally enters the screening stage, reducing material loss and ineffective conveying. The aforementioned negative pressure guiding device 11 is prior art and will not be described in detail here. Of course, other types of guiding devices 1 in the prior art can also be set as needed, and no further restrictions are imposed here.
[0032] Compared with the prior art, the present invention provides a material guiding and straightening mechanism for a screening machine, which has the following beneficial effects: The present invention is provided with a vertical moving device, a horizontal moving device, and a front-back moving device. The vertical moving device is connected to the horizontal moving device to drive the horizontal moving device to move vertically. The horizontal moving device is connected to the front-back moving device to drive the front-back moving device to move horizontally. The front-back moving device is connected to the straightening device to drive the straightening device to move front-back. Through the above methods, the present invention can realize the vertical, horizontal, left-right, and front-back position adjustment of the straightening device, so that one straightening device can better meet the material straightening requirements at different positions of the screening machine, and improve the applicability of the material guiding and straightening mechanism.
[0033] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
