[0046] The following refers to Figures 1 to 11 The bullet weighing device and the bullet weighing and classifying system according to the embodiments of the present application are described.

[0047] As Figure 7 , Figure 10As shown, the bullet weighing device according to an embodiment of the present invention includes a sorting device 200 and a weighing mechanism 300. The sorting device 200 includes a sorting rotation drive unit 210 and a sorting roller 220 that can be driven to rotate by the sorting rotation drive unit 210. The sorting roller 220 is provided with at least one receiving groove 221 that can only receive a single bullet 900 horizontally. The receiving groove 221 can rotate with the sorting roller 220 to a sorting receiving position that allows the bullet 900 to horizontally enter the receiving groove 221. The receiving groove 221 can rotate with the sorting roller 220 to a sorting receiving position that allows the bullet 900 to horizontally enter the receiving groove 221. The machine rotates to the sorting and discharge station where bullets 900 are poured out of the receiving trough 221; the weighing mechanism 300 includes a receiving component 310, a weighing drive unit 320 and a weighing sensor 330. The receiving component 310 is provided with a weighing trough 311 that can receive bullets 900 poured out of the receiving trough 221. The weighing sensor 330 can weigh the bullets 900 in the weighing trough 311. The weighing drive unit 320 is connected to the receiving component 310 and can drive the receiving component 310 to move to pour bullets 900 out of the weighing trough 311.

[0048] During operation, the receiving trough 221 is in the sorting and receiving position. A single bullet 900 is horizontally fed into the receiving trough 221 from the bullet conveying device or input channel. The sorting rotation drive unit 210 drives the sorting roller 220 to rotate, causing the receiving trough 221 to rotate to the sorting and discharging position. The single bullet 900 is tilted out and enters the weighing trough 311. The weighing sensor 330 weighs the bullet 900 in the weighing trough 311. After weighing, the bullet 900 is tilted out of the weighing trough 311, thus completing the weighing of a single bullet. Because it is sorted by the sorting device 200, it is ensured that only one bullet falls into the weighing trough 311 each time, resulting in high reliability of weighing. Moreover, the bullet can be horizontally transferred and weighed, ensuring high safety.

[0049] Specifically, the bullet weighing device is equipped with a control module. The sorting rotation drive unit 210, the weighing drive unit 320, and the weighing sensor 330 are all connected to the control module. The control module, in conjunction with the set sensor, controls the action of the sorting rotation drive unit 210 and the weighing drive unit 320, thereby realizing continuous weighing operation and making the bullet weighing device have high working efficiency.

[0050] It should be noted that in some embodiments of this utility model, the horizontal placement or rolling of the bullet 900 means that the outer peripheral surface of the bullet 900 is in contact with the supporting surface, and the length direction of the bullet 900 is approximately parallel to the supporting surface.

[0051] like Figure 11 As shown, in some embodiments of this utility model, the opening of the receiving trough 221 at the sorting and receiving station faces upward to facilitate receiving the bullet 900, and the opening of the receiving trough 221 at the sorting and discharging station faces downward to facilitate dumping the bullet 900.

[0052] As Figure 7 , Figure 10 shown, in some embodiments of the utility model, bullet weighing device still includes input channel 110, input channel 110 is obliquely arranged and can be supplied with bullet 900 roll, and the sorting roller 220 is located at the export of input channel 110, by the configuration oblique input channel 110, bullet 900 can utilize the self weight and automatically roll to the receiving groove 221 of sorting roller 220.

[0053] It can be understood that, in some embodiments of the utility model, the receiving groove 221 of the sorting roller 220 can also be directly arranged to the export of bullet conveying device such as conveying belt mechanism, vibrating feeder disc etc., and the function of sending bullet into the receiving groove 221 can be realized.

[0054] In some embodiments of the utility model, the receiving groove 221 is arranged at the circumferential surface of the sorting roller 220, and the opening width of the receiving groove 221 is greater than the outer diameter of the bullet 900 and less than twice the outer diameter of the bullet 900, so as to ensure that the receiving groove 221 can only receive a single bullet each time.

[0055] As Figure 11 shown, in some embodiments of the utility model, one side of the opening of the receiving groove 221 is connected to the outer circumferential surface 220a of the sorting roller 220, and the other side of the opening of the receiving groove 221 extends along the rotation direction of the sorting roller 220 to form an extension surface 222, and the minimum distance D from the extension surface 222 to the opposite side of the opening of the receiving groove 221 is greater than the outer diameter of the bullet 900 and less than twice the outer diameter of the bullet 900.

[0056] Specifically, the opening of the receiving groove 221 faces the rotation direction of the sorting roller 220, so as to facilitate receiving the bullet 900, and the minimum distance D is 1.05 to 1.4 times the outer diameter of the bullet 900, so as to ensure that the bullet 900 can smoothly enter the receiving groove 221.

[0057] In some embodiments of the utility model, the distance from the midpoint of the minimum distance D from the extension surface 222 to the opposite side of the opening of the receiving groove 221 to the outer circumferential surface 220a of the sorting roller 220 is greater than 0.5 times the outer diameter of the bullet 900 and less than the outer diameter of the bullet 900, so as to reduce the situation that the next bullet is taken away by the receiving groove 221.

[0058] Specifically, one side of the opening of the receiving groove 221 is connected to the outer circumferential surface 220a of the sorting roller 220, but has a set transition distance (to avoid forming a sharp corner) from the outer circumferential surface 220a of the sorting roller 220, the distance from the midpoint of the extension surface 222 to the opposite side of the opening of the receiving groove 221 to the outer circumferential surface 220a of the sorting roller 220 is greater than 0.5 times the outer diameter of the bullet 900, less than the outer diameter of the bullet 900, so that the transition distance is less than 0.5 times the outer diameter of the bullet 900, even if the next bullet part enters the opening of the receiving groove 221, only less than half of the bullet enters the opening of the receiving groove 221, when the sorting roller 220 rotates (such as Figure 11 clockwise rotation), the next bullet will be automatically pushed back to the input channel 110, thereby avoiding the situation that the next bullet is taken away, so as to ensure that the sorting device 200 sends out only one bullet at a time.

[0059] As shown in Figure 11 some embodiments of the utility model, the extension surface 222 is a curved surface, and the extension surface 222 protrudes towards the outside of the sorting roller 220, so as to reduce the situation that the bullet 900 stays at the extension surface 222.

[0060] Specifically, by protruding the extension surface 222 towards the outside of the sorting roller 220, the distance from the extension surface 222 to the outer circumferential surface of the sorting roller 220 is reduced, thereby reducing the situation that the bullet 900 stays at the extension surface 222 and reducing the situation that two bullets are taken away at a time.

[0061] As shown in Figure 11 some embodiments of the utility model, the distance from the extension surface 222 to the outer circumferential surface of the sorting roller 220 gradually decreases along the rotation direction of the sorting roller 220, so as to reduce the situation that two bullets are taken away at a time.

[0062] As shown in Figure 11 some embodiments of the utility model, the receiving groove 221 rotates with the sorting roller 220 to a sorting and receiving station where the bullet 900 can enter the receiving groove 221 horizontally, at this time, the receiving groove 221 is lower than the horizontal line 220b where the axis of the sorting roller 220 is located, that is, the outlet of the input channel 110 is lower than the horizontal line 220b, even if the next bullet 900a is stacked on the bullet 900 in the receiving groove 221, the center of gravity of the bullet 900a is located outside the contact point of the bullet 900 in the receiving groove 221, when the sorting roller 220 rotates clockwise, the bullet 900a will still automatically fall back to the input channel 110, thereby reducing the situation that two bullets are taken away at a time in the receiving groove 221.

[0063] As shown in Figure 11As shown in some embodiments of the utility model, the structure can cooperate with the outward convex extension surface 222, so that the center of gravity of the stacked bullets 900a is more outward, and the stacked bullets 900a are more easily dropped.
