[0019] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In order to make the purpose, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. For those skilled in the art, the present invention can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of the present invention by illustrating examples of the present invention.

[0020] like Figure 1 、 Figure 2 and Figure 3 As shown, the utility model provides a technical solution of a screw powder adding and feeding mechanism: it includes a frame 1, a powder adding mechanism is provided on the frame 1, the powder adding mechanism includes a feeding seat 31, a material box 32 is provided above the feeding seat 31, a box cover 33 is provided on the material box 32, a material pipe 35 is passed through the top of the box cover 33, a screw guide tube 38 is provided below the feeding seat 31, a material port 381 is provided on the screw guide tube 38, the material port 381 is communicated with the material box 32, a feeding motor 39 is installed at the end of the screw guide tube 38, a feeding screw 40 is connected to the output end of the feeding motor 39, the feeding screw 40 extends into the screw guide tube 38, a powder adding upper nozzle 41 is installed at the outer end of the screw guide tube 38, and a powder adding lower nozzle 42 is installed below the powder adding upper nozzle 41.

[0021] Among them, the screw guide tubes 38 are arranged in multiple groups side by side, all of which are connected to the material box 32. This design can realize the powder adding operation of multiple groups of screw guide tubes 38 at the same time, greatly improving the powder adding efficiency.

[0022] The material box 32 and the box cover 33 are connected by a lock 34. This connection method is convenient for quickly opening and closing the material box, which is convenient for adding and cleaning materials.

[0023] An air breathing valve 36 is installed on the top of the box lid 33, and a pneumatic vibrator 37 is installed on the side of the material box 32. The air breathing valve 36 effectively balances the air pressure inside and outside the material box, preventing excessive dust from being generated during the powder addition process. The pneumatic vibrator 37 vibrates the material box to prevent material blockage and ensure smooth powder addition.

[0024] Among them, a translation mechanism is provided below the screw guide tube 38, and the translation mechanism includes a translation motor 21, the output end of the translation motor 21 is connected to a screw rod 22, and the tail end of the screw rod 22 is installed on the bottom wall of the frame 1 through a positioning seat 23, and a nut 24 is sheathed on the screw rod 22, and a translation seat 25 is installed on the nut 24, and the translation seat 25 is connected to multiple sets of screw guide tubes 38.

[0025] Among them, slide rails 26 are provided on both sides of the screw rod 22, and a slide seat 27 is slidably mounted on the slide rails 26, and the slide seat 27 is connected to the translation seat 25. This design allows the translation mechanism to move smoothly, ensuring the accuracy and reliability of the powder adding process.

[0026] According to the above scheme, in this embodiment, the translation motor 21 is first activated, causing the translation mechanism to drive the screw guide tube 38 to move horizontally. By controlling the speed and operating time of the translation motor 21, the movement distance and speed of the screw guide tube 38 can be precisely controlled, thereby achieving powder addition requirements at different locations.

[0027] Next, the feeding motor 39 is activated, causing the feeding screw 40 to rotate and advance downward. The feeding screw 40 feeds the material from the material box 32 through the material pipe 35 and the material port 381 into the screw guide tube 38. The rotation and advancement of the feeding screw 40 evenly fills the screw guide tube 38 with material, ensuring uniform powder addition.

[0028] During the powder adding process, the pneumatic vibrator 37 is periodically started to vibrate the material box 32. This helps to loosen the material and prevent the material from agglomerating or clogging in the material box, thereby ensuring the smooth progress of the powder adding process.

[0029] At the same time, the air breathing valve 36 plays a role in balancing the air pressure inside and outside the material box during the powder adding process. When the material in the material box 32 is drawn out, the air breathing valve 36 allows external air to enter to replenish the pressure in the material box and prevent excessive dust from being generated due to excessive pressure difference.

[0030] When the material in the screw guide tube 38 reaches a certain amount, the powder adding nozzle 41 and the powder adding nozzle 42 evenly spray the material to the target location. The design of the powder adding nozzle 41 and the powder adding nozzle 42 ensures the uniform distribution of the material during the spraying process, thereby improving the efficiency and quality of the powder adding.

[0031] The entire powder adding process is precisely controlled by the control system, and the operator only needs to set the parameters to achieve automatic powder adding. In addition, the modular design makes the maintenance and replacement of various components very convenient, greatly improving the efficiency and maintenance convenience of the equipment.

[0032] To sum up, the screw powder feeding mechanism of the utility model significantly improves the uniformity, efficiency and cleanliness of powder adding through the synchronous movement of multiple sets of screw guide tubes, the assistance of air breathing valves and pneumatic vibrators, and the maintenance convenience of modular design, and is suitable for filling various powder materials.

[0033] The working principle and use process of the present invention are as follows: After assembling the various components of the present invention in sequence, all the working steps can be completed by working in accordance with the above implementation methods in sequence according to actual needs.
