[0002] Powder coatings require precise weighing during packaging to ensure consistent box weight. Traditional manual weighing methods are inefficient and susceptible to human error, leading to significant inaccuracies.

[0003] Existing automated weighing equipment mostly uses electronic scales or volumetric metering, which are complex in structure and require high powder flowability, especially prone to clogging or inaccurate measurement during continuous discharge. Furthermore, some devices are difficult to adapt to different packaging specifications, and the adjustment process is cumbersome, affecting production efficiency. Therefore, there is an urgent need for a simple, accurate, and easily adjustable powder coating packaging and weighing device to meet the requirements of efficient and stable production. This paper proposes a powder coating packaging and weighing device. Utility Model Content

[0008] Furthermore, the mounting bracket is a circular plate with fan-shaped grooves evenly spaced on the side, and the linkage rod is a T-shaped circular rod with a splined side.

[0009] Furthermore, the auxiliary component includes an adjusting plate that is threadedly installed on the inner side of the discharge cylinder at equal intervals. The sides of the adjusting plate are staggered with first slots that penetrate through them. The upper side of the adjusting plate is provided with mating plates at equal intervals. The sides of the mating plates are provided with second slots that penetrate through them corresponding to the positions of the first slots.

[0025] Example: Figures 1 to 2As shown, a powder coating packing and weighing device includes a discharge cylinder 1, which is a hollow cylindrical cylinder. A feed cylinder 11 is fixedly installed on the upper side of the discharge cylinder 1. The feed cylinder 11 is a hollow funnel-shaped cylindrical cylinder. Two sets of blocking plates 2 are mirror-arranged on the lower side of the discharge cylinder 1. The blocking plates 2 are semi-circular plates. An electric push rod 21 is mirror-rotatably installed on the side of the discharge cylinder 1 corresponding to the position of the blocking plates 2, and the output end of the electric push rod 21 is rotatably installed on the side of the blocking plates 2. A limiting plate 22 is rotatably installed on the side of the blocking plates 2 and is slidably arranged on the side of the discharge cylinder 1. The limiting plate 22 is an arc-shaped frame. A drivable drive assembly 3 is arranged inside the discharge cylinder 1. A weighing auxiliary assembly 4 is arranged inside the discharge cylinder 1 corresponding to the position above the drive assembly 3.

[0026] Specifically, the set drive component 3 can perform unified drive operation, driving the set auxiliary component 4 to output powder coating in a step-by-step quantitative manner, thereby achieving accurate weighing and discharging.

[0027] like Figure 2 and Figure 3 As shown, the drive assembly 3 includes a mounting bracket 31 threadedly mounted inside the discharge cylinder 1. The mounting bracket 31 is a circular plate with fan-shaped grooves evenly spaced on the side. A linkage rod 32 is provided on the upper side of the mounting bracket 31. The linkage rod 32 is a T-shaped circular rod with a splined side. A mating groove 33 is provided on the lower side of the linkage rod 32. The mating groove 33 is a circular threaded groove. A motor 34 is fixedly mounted at the center position on the upper side of the mounting bracket 31. A mating thread 35 is provided at the output end of the motor 34. The mating thread 35 is a threaded groove. The output end of the motor 34 can be threadedly mounted inside the mating groove 33 by engaging with the mating thread 35.

[0028] Specifically, after the linkage rod 32 is inserted into the position of the subsequent component, it can be installed on the inner side of the discharge cylinder 1 through the mounting bracket 31, which drives the motor 34 to move upward, so that the mating thread 35 and the mating groove 33 are threadedly engaged. At this time, the output end of the motor 34 is fixedly connected to the linkage rod 32, and the motor 34 can drive the linkage rod 32 to rotate.

[0029] like Figure 2 and Figures 4 to 6As shown, the auxiliary component 4 includes an adjusting plate 41 that is equidistantly threaded inside the discharge cylinder 1 and is movably sleeved on the side of the linkage rod 32. The adjusting plate 41 is a circular ring plate with threads on the outer side. First slots 42, which are fan-shaped, are staggered on the side of the adjusting plate 41. The angle of the staggered first slots 42 depends on the number of adjusting plates 41, such as three sets at 120 degrees, four sets at 90 degrees, and so on. Matching plates 43 are equidistantly arranged on the upper side of the adjusting plate 41 and are splinedly sleeved on the side of the linkage rod 32. The matching plates 43 are circular ring plates with splined inner sides. Second slots 44, which are fan-shaped, are formed on the side of the matching plates 43 corresponding to the first slots 42. Rotating blocks 45 are rotatably mounted on the upper side of the adjusting plate 41 and fixedly mounted on the lower side of the corresponding matching plates 43. 45 is an L-shaped annular block. A first mounting groove 46 is provided on the side of the uppermost mating plate 43 above the adjusting plate 41. The first mounting groove 46 is a T-shaped cylindrical threaded groove. A plug 461 is threadedly installed inside the first mounting groove 46. The plug 461 is a T-shaped circular block. A second mounting groove 47 is provided on the side of the mating plate 43, which is fixedly connected to the rotating block 45, corresponding to the position of the first mounting groove 46. The second mounting groove 47 is a cylindrical threaded groove. A third mounting groove 48 is provided on the side of the other mating plates 43, corresponding to the positions of the first mounting groove 46 and the second mounting groove 47. The third mounting groove 48 is a cylindrical groove. A constraint rod 471 is threadedly installed inside the second mounting groove 47. The constraint rod 471 is movably positioned inside the third mounting groove 48 and the first mounting groove 46. The second mounting groove 47 is a cylindrical rod with a threaded section.

[0030] Specifically, during installation, first, the constraint rod 471 is installed inside the second mounting groove 47 on the side of the adjacent mating plate 43 of the adjusting plate 41. A corresponding number of mating plates 43 are quantitatively set on the upper side of the adjusting plate 41 according to requirements. Then, the mating plates 43 with the third mounting groove 48 on their sides are gradually fitted onto the side of the constraint rod 471, and then the mating splines are fitted onto the side of the linkage rod 32 at the constraint position. Finally, the mating plate 43 with the first mounting groove 46 is placed at the uppermost position, and the plug 461 is installed inside the first mounting groove 46 to seal it. Then, the adjusting plate 41, along with the mating plates 43 on its side, is threaded... Place the device inside the discharge cylinder 1 to secure all the adjusting plates 41 in the correct positions. Then, insert the linkage rod 32 into the inner side of the mating plate 43 using the same method. Finally, thread the mounting bracket 31 so that the output end of the motor 34 is threaded into the mating groove 33. In use, the motor 34 drives the linkage rod 32 to rotate, causing all the mating plates 43 to rotate synchronously. The powder coating inside the feed cylinder 11 flows in and fills the space of the second slot 44. As the second slot 44 rotates, the powder coating gradually falls down from the first slot 42, thus completing the quantitative weighing and output of the powder coating.

[0031] In summary, the powder coating packing and weighing device uses a drive assembly to rotate a linkage rod, causing the second slot on the mating plate to alternately engage with the first slot on the adjusting plate, achieving a step-by-step quantitative drop of the powder coating. Specifically, after the powder enters from the feed cylinder, it fills the volume of the second slot. As the linkage rod rotates, the powder falls sequentially through the first slots of each adjusting plate, and finally, the outlet is controlled by a blocking plate to achieve accurate weighing. This structure avoids the errors caused by single-drop material in traditional weighing methods. Furthermore, by increasing or decreasing the number of adjusting plates and mating plates, or adjusting the slot angles (e.g., three sets of 120°, four sets of 90°), it can flexibly adapt to different weighing needs, improving the device's versatility and production efficiency. In addition, the modular threaded connection and spline socket design facilitate disassembly and maintenance, reducing operating costs and ensuring long-term stable operation.
