The length is equal to the width of the protrusion, so that the length of the powder filling plate 3 can be greater than the length of the powder leakage plate 1. At the same time, the rear end of the tail plate 4 can be connected to a driving device to drive the powder filling plate 3 to move, such as an electric push rod, a cylinder, an oil cylinder, etc., and the metal powder can fall into the material guide groove 301 and be pushed to the front end of the powder leakage plate 1 by moving the powder filling plate 3 backward and then forward, so as to achieve precise powder filling. At the same time, the size of the internal space of the material guide groove 301 can be adjusted by the adjustment component 5 as needed to achieve quantitative powder filling.

[0027] Among them, a powder leakage hole 101 is opened in the middle of the upper surface of the front end of the powder leakage plate 1, and the diameter of the powder leakage hole 101 is equal to the width of the material guide groove 301; the powder leakage hole 101 can drop the metal powder taken from the powder filling plate 3, and the circular powder leakage hole 101 can make the metal powder drop smoothly and avoid the metal powder sticking to the inner wall of the powder leakage hole 101.

[0028] Among them, the material guide groove 301 and the adjustment component 5 together enclose a material guide hole, and the position of the material guide hole corresponds to the position of the powder leakage hole 101; by adjusting the adjustment component 5, the length of the material guide hole can be increased or decreased as needed, so that when the powder filling plate 3 moves backward to take material, the volume of the accommodating space formed between the material guide hole, the powder leakage plate 1 and the inner wall of the slide groove 203 is changed, so that the weight of the metal powder contained in this accommodating space can be flexibly changed, thereby achieving precise filling.

[0029] Among them, a slide groove 203 adapted to the powder filling plate 3 is opened in the middle of the bottom end of the powder storage plate 2, and the powder filling plate 3 is slidably connected to the inside of the slide groove 203; through the cooperation between the slide groove 203 and the powder filling plate 3, the powder filling plate 3 can slide back and forth between the slide groove 203 and the powder leakage plate 1, ensuring that the powder filling plate 3 moves smoothly and stably.

[0030] Among them, a powder storage groove 201 is opened on the upper surface of the rear end of the powder storage plate 2, and a powder dropping hole 202 is opened in the middle of the inner bottom wall of the powder storage groove 201, and the position of the powder dropping hole 202 corresponds to the position of the material guide hole; before use, the metal powder can be poured into the powder storage groove 201, and when the powder filling plate 3 moves backward and makes the material guide hole correspond to the powder dropping hole 202, the metal powder can fall into the material guide hole through the powder dropping hole 202.

[0031] The adjusting assembly 5 includes a T-shaped block 7, the protruding end of the T-shaped block 7 is slidably connected to the inside of the material guide groove 301, the two ends of the T-shaped block 7 are located on both sides of the material guide groove 301, and through holes are provided at both ends of the front of the T-shaped block 7. A pin 6 is slidably connected inside the through hole. The end of the pin 6 away from the T-shaped block 7 is fixedly connected to the front of the powder filling plate 3, and a mounting groove 701 is provided on the front of the T-shaped block 7 and located between the two pins 6; the protruding end of the T-shaped block 7 and the material guide groove 301 are connected to each other. A material guide hole is formed in the material guide slot 301. By setting a T-block 7, the T-block 7 can be pulled forward and backward to slide on the pin 6, so that the protruding end of the T-block 7 can slide forward and backward in the material guide slot 301, and the width between the protruding end of the T-block 7 and the material guide slot 301 can be changed, so that the width of the material guide hole is changed, so that the material taking amount of the material guide hole when taking material is changed, and quantitative material taking is realized, avoiding the back and forth replacement of the powder filling plate 3, which not only saves manpower and material resources, but also saves time cost.

[0032] Among them, the mounting groove 701 is arranged in a cross shape, and the left and right ends of the mounting groove 701 are respectively connected with the corresponding through holes, and an insert 8 is installed inside the mounting groove 701; the insert 8 and the mounting groove 701 can adopt an interference fit or a clearance fit. When a clearance fit is adopted, the insert 8 and the T-block 7 can be connected by screws, and the specific screw position can be set as needed.

[0033] Among them, arc grooves 801 that are compatible with the through hole are opened at the left and right ends of the insert 8, a cavity 802 is opened inside the insert 8, and guide grooves 803 are opened on the inner walls of the left and right sides of the cavity 802. Guide holes 804 are opened on the inner wall on the side away from each other of the two guide grooves 803, and the end of the guide hole 804 away from the guide groove 803 is connected with the arc groove 801, and the diameter of the guide hole 804 is smaller than the diameter of the guide groove 803. A mounting hole 805 is opened in the middle of the front side of the insert 8, and the mounting hole 805 is connected with the cavity 802; the arc groove 801 cooperates with the through hole so that the pin 6 can contact the inner wall of the arc groove 801.

[0034] The cavity 802 is provided with an adjusting screw 9, the middle part of which is threadedly connected with a movable block 901, and the two guide holes 804 are slidably connected with locking columns 903, and the ends of the two locking columns 903 that are far away from each other respectively penetrate the corresponding arc groove 801 and contact the corresponding pin 6, and the outer sides of the ends of the two locking columns 903 that are close to each other are sleeved with an annular plate 905, and the outer sides of the locking columns 903 are sleeved with a spring 906, and the two ends of the spring 906 are respectively fixedly connected to one side of the annular plate 905 and the inner wall of the guide groove 803, and the annular plate 905 is slidably matched with the inside of the guide groove 803; the right ends of the two locking columns 903 that are close to each other are respectively connected with the movable block 901, and the movable block 901 is slidably matched with the movable block 901. The left and right sides of the movable block 901 are in contact, and a groove is provided in the middle of the front end of the adjusting screw 9, and the adjusting screw 9 can be rotated by cooperating with a flat-head screwdriver and the groove. When the adjusting screw 9 is rotated, it can drive the movable block 901 thereon to move back and forth in the cavity 802, and the movable block 901 can drive the locking columns 903 on both sides to move away from each other. At the same time, the locking column 903 drives the annular plate 905 to move in the guide groove 803 and squeeze the spring 906, so that the locking column 903 passes through the arc groove 801 and abuts against the side of the pin 6, thereby positioning the position of the T-block 7. When the position of the T-block 7 needs to be adjusted, it is only necessary to rotate the adjusting screw 9 in the opposite direction to disengage the locking column 903 from the pin 6.

[0035] The rear end of the adjusting screw 9 is rotatably connected to the rear inner wall of the cavity 802 through a bearing, and the front end of the adjusting screw 9 slides through the mounting hole 805 and extends to the outside. The upper surface and the lower surface of the movable block 901 are respectively slidably connected to the inner top wall and the inner bottom wall of the cavity 802. The ends of the two locking posts 903 that are close to each other are both arranged in an arc shape. The left and right sides of the movable block 901 are provided with an arc-shaped slideway 902. The ends of the two locking posts 903 that are close to each other are slidably connected to the inside of the slideway 902. The ends of the two locking posts 903 that are away from each other are provided with an arc surface 904, and the inner side of the arc surface 904 is fixedly connected with an anti-skid layer; by enabling the two annular plates 905 to always approach the inside under the action of the spring 906, the ends of the two locking posts 903 that are close to each other are always in contact with the slideway 902. At the same time, the two locking posts 903 can press against the movable block 901 under the action of the spring 906 to prevent the movable block 901 from being displaced without the action of external force.

[0036] Working principle: before use, connect the driving device to the tail plate 4 so that the driving device can drive the powder filling plate 3 to move forward and backward through the tail plate 4. Then adjust the adjustment component 5 according to the required filling amount. Use the flat head screwdriver and the groove to make the adjustment screw 9 rotate in the opposite direction. When the adjustment screw 9 rotates in the opposite direction, it can drive the movable block 901 on it to move backward in the cavity 802. Under the action of the slideway 902 and the spring 906, the two locking columns 903 can be brought close to each other, so that the ends of the two locking columns 903 that are away from each other are separated from the pin 6.

[0037] Then the T-block 7 can be moved inward or outward to change the width between the protruding end of the T-block 7 and the guide groove 301, thereby changing the amount of powder falling. When the T-block 7 is adjusted to a suitable position, the adjusting screw 9 can be rotated forward to make the movable block 901 move forward in the cavity 802. At the same time, the ends of the two locking columns 903 that are close to each other can slide toward the middle of the movable block 901 through the corresponding slideway 902, so that the two locking columns 903 are moved away from each other under the squeezing force of the movable block 901. At the same time, the annular plate 905 can compress the spring 906, so that the locking column 903 passes through the arc groove 801 and abuts against the side of the pin 6, thereby positioning the position of the T-block 7.

[0038] Then pour the metal powder into the powder storage tank 201, and drive the tail plate 4 to move backward and then forward through an external driving device. At the same time, the tail plate 4 drives the powder filling plate 3 to move backward first, so that the guide hole on the powder filling plate 3 corresponds to the powder dropping hole 202, and the metal powder can fall into the guide hole through the powder dropping hole 202. Then the powder filling plate 3 moves forward again, and the powder filling plate 3 can drive the taken out metal powder to move forward to the powder leakage hole 101, so that the metal powder is discharged through the powder leakage hole 101.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
