[0044] like Figures 1 to 9 As shown, the embodiment of the utility model provides a surface particle coating device, comprising:

[0045] First column 3;

[0046] A second column 5, parallel to the first column 3;

[0047] A lifting drive unit 4 is provided on the first column 3 and the second column 5;

[0048] The hopper 22 has two ends connected to the lifting drive unit 4, so that the lifting drive unit 4 drives the hopper 22 to move upward or downward relative to the first column 3 and the second column 5.

[0049] The discharging portion 6 is located in the hopper 22 and connected to the lifting driving portion 4 .

[0050] In the embodiment of the utility model, the device realizes the smooth lifting and lowering of the hopper 22 along the first column 3 and the second column 5 by setting the lifting drive unit 4, ensures the stability and accuracy of the lifting process of the hopper 22, improves the work efficiency, and reduces the difficulty of operation. Secondly, the discharge part 6 is located in the hopper 22 and is connected to the lifting drive unit 4, so that the material can be discharged accurately and quickly at a predetermined position, which not only ensures the uniformity and continuity of the material discharge, but also avoids the waste and pollution of the material, and improves the utilization rate of the raw materials. In addition, since the first column 3 and the second column 5 are parallel to each other, it provides greater flexibility and stability for the lifting and lowering of the hopper 22, ensuring the flatness and quality of the surface particle coating. Therefore, the surface particle coating device not only improves the work efficiency and raw material utilization, but also ensures the surface quality and flatness of the product.

[0051] like Figures 1 to 9 As shown, the lifting drive unit 4 includes:

[0052] A first motor 41 is disposed on the first column 3, wherein an output shaft of the first motor 41 is connected to a first coupling 43, and the first coupling 43 is connected to two worm gears;

[0053] A first screw rod 42, one end of which is connected to a first coupling 43 via a worm, and the other end of which is threadedly connected to a first nut 44, wherein the first nut 44 is disposed on the second support plate 26;

[0054] A synchronization shaft 45, one end of which is connected to the first coupling 43 through another worm, and the other end of which is connected to the second coupling 46, and the second coupling 46 is arranged on the first column 3;

[0055] A second screw rod 47, one end of which is connected to the second coupling 46 through a worm, and the other end of which is threadedly connected to a second nut 48, wherein the second nut 48 is disposed on the first support plate 23; a first slide rail 31 is disposed on one side of the first column 3; a second slide rail 51 is disposed on the side of the second column 5 opposite to the first column 3; the lifting drive unit 4 further includes:

[0056] A second support 27 connected to one end of the hopper 22 and to one end of the first support plate 23;

[0057] A plurality of second sliders 28 are provided, and the plurality of second sliders 28 are provided on the second support 27, and a slide groove matching with the second slide rail 51 is provided on the second slider 28, so that the second slider 28 is slidably connected with the second slide rail 51;

[0058] A first support 24 is connected to the other end of the hopper 22 and to one end of the second support plate 26;

[0059] The first sliding block 25 is disposed on the first support 24 , and a sliding groove matched with the first sliding rail 31 is disposed on the first sliding block 25 , so that the first sliding block 25 is slidably connected with the first sliding rail 31 .

[0060] In the embodiment of the utility model, the first coupling 43 is driven by the first motor 41, and then the two worms are driven to rotate simultaneously, so that the first screw 42 and the second screw 47 can realize synchronous rotation through their respective screw nuts, ensuring the stability and synchronization of the hopper 22 during the lifting process, and avoiding the device failure or product quality problems caused by the asynchronous lifting. Secondly, the setting of the first slide rail 31 and the second slide rail 51, in conjunction with the first slider 25 and the second slider 28, provides a smooth and precise guide for the lifting of the hopper 22. The sliding connection mode not only reduces the friction resistance during the lifting process, but also improves the wear resistance and service life of the device. In addition, the hopper 22 is firmly connected to the lifting drive unit 4 through the first support 24 and the second support 27, ensuring that the hopper 22 will not shake or deflect during the lifting process, thereby ensuring the accuracy and continuity of material discharge. Therefore, the design of the lifting drive unit 4 not only improves the stability and work efficiency of the device, but also ensures the surface quality and precision of the product, and its structure is compact, easy to operate and convenient to maintain.

[0061] like Figures 1 to 9 As shown, the hopper 22 is provided with a partition 21, so that the partition 21 divides the hopper 22 into a plurality of separate spaces; the discharge portion 6 includes:

[0062] A variable frequency motor 61 is fixedly connected to the second support 27;

[0063] One end of the blanking shaft 62 passes through the hopper 22 and is connected to the output end of the variable frequency motor 61 , and the other end passes through the hopper 22 and is connected to a bearing seat 63 fixed on the first support 24 .

[0064] In the embodiment of the utility model, by setting a partition 21 on the hopper 22, the inside of the hopper 22 is divided into a plurality of separate spaces, so that materials of different types or properties can be stored and transported separately, avoiding mixing and contamination between materials. At the same time, the plurality of separate spaces can also be flexibly adjusted as needed to adapt to different production requirements and material characteristics. Secondly, the discharge part 6 adopts the method of driving the blanking shaft 62 by the variable frequency motor 61 to achieve precise control of material discharge. The variable frequency motor 61 can adjust the speed and direction according to actual needs, thereby controlling the rotation speed and direction of the blanking shaft 62, and then controlling the discharge amount and uniformity of the material, which not only improves the accuracy and continuity of material discharge, but also avoids waste and pollution of materials. In addition, one end of the blanking shaft 62 is connected to the output end of the variable frequency motor 61, and the other end penetrates the hopper 22 and is connected to the bearing seat 63 fixed on the first support 24, so that the blanking shaft 62 is more stable and reliable during the rotation process, reducing the possibility of failure and improving the service life of the device. Therefore, the design of the hopper 22 and the discharge part 6 not only improves the flexibility and adaptability of the device, but also ensures the accuracy and continuity of material discharge. It has a compact structure, simple operation and convenient maintenance.

[0065] like Figures 1 to 9 As shown, the blanking shaft 62 is located in the blanking trough 221, and a plurality of slots 621 are provided on the blanking shaft 62; a transverse cover plate 2 is provided on the hopper 22, and a vertical cover plate 1 is provided on the first column 3; four first slide blocks 25 are provided, and every two first slide blocks 25 are provided on one first slide rail 31, and the two first slide rails 31 are parallel to each other;

[0066] Four second sliding blocks 28 are provided, and every two second sliding blocks 28 are provided on one second slide rail 51 , and the two second slide rails 51 are parallel to each other; the slot 621 and the blanking shaft 62 are integrally formed.

[0067] In the embodiment of the utility model, the blanking shaft 62 is located in the blanking trough 221, and a plurality of slots 621 are provided on the blanking shaft 62. Such a design allows the material to be spread more evenly on the surface of the substrate through the slots 621, thereby improving the uniformity and efficiency of spreading. At the same time, the slots 621 are integrally formed with the blanking shaft 62, thereby enhancing the integrity and stability of the structure. The arrangement of the horizontal cover plate 2 and the vertical cover plate 1 effectively prevents the splashing and scattering of the material during the spreading process, protects the working environment and the safety of the operator, and also reduces the waste of the material. The number and layout design of the first slider 25 and the second slider 28 make the hopper 22 more stable and smooth during the lifting process. The four first sliders 25 are respectively arranged on two mutually parallel first slide rails 31, and the four second sliders 28 are respectively arranged on two mutually parallel second slide rails 51. Such a design not only improves the smoothness of sliding, but also enhances the carrying capacity and stability of the device. The integral molding design of the slots 621 and the blanking shaft 62 not only simplifies the manufacturing process, but also improves the strength and durability of the components. The connection points between components are reduced, thereby reducing the possibility of failure and extending the service life of the device. The outer diameter of the blanking shaft 62 is just slightly smaller than the lateral width of the blanking trough 221, so that the blanking shaft 62 can just rotate in the blanking trough 221, so that during the rotation, the granular material can fall into the slot 621. When the slot 621 rotates to a downward direction, the granular material will automatically fall due to its own weight. The depth of the slot 621 is shallower, so that the granular material can be stored without delaying the falling.

[0068] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
