[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0041] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] like Figure 1 The steel ball packaging production line shown mainly includes a ball screening machine 1, a screw rod 2, a high-precision electronic scale 3 and a conveyor belt 4.

[0043] Among them, the ball screening machine 1 is used to screen steel balls, and the ball screening machine disclosed in "CN206286207U" and "CN210304584U" can be used. The ball screening machine 1 is provided with a spiral body 8, which is similar to a spring structure. A channel is provided in the middle of the spiral body 8, and the steel balls pass through the channel. The spiral pitch of the spiral body 8 is a set value, and the spiral pitch is slightly smaller than the outer diameter of the qualified steel balls, so the unqualified smaller steel balls leak out from the spiral space. Through the rotation of the spiral body 8 around its own axis, on the one hand, the steel balls can be transported, and on the other hand, unqualified small steel balls can be screened out. About one steel ball is discharged from the right end of the ball screening machine 1 for each rotation.

[0044] The discharge port of the ball screening machine 1 is provided with an inclined platform 9, which is a plate arranged obliquely (refer to Figure 3 ), the lower edge of the inclined platform 9 is provided with a spiral rod 2. Figure 3 The steel balls 13 discharged one by one from the ball screening machine 1 reach the lower edge of the inclined platform 9 after being guided by the inclined platform 9, and the steel balls 13 contact the screw rod 2.

[0045] The grooves formed between adjacent threads of the screw rod 2 are used to accommodate the steel balls 13. A baffle plate 10 is also provided on the side of the screw rod 2, and a ball placement space is defined between the baffle plate 10 and the groove of the screw rod 2. The ramp 9 has a bottom plate 12, which extends in the transmission direction of the screw rod 2 and is connected to the baffle plate 10. In this example, the ramp 9 and the baffle plate 10 are integrally arranged, which is easy to maintain and also makes the structure compact.

[0046] The grooves between the threads of the screw rod 2 are also set according to the outer diameter of the qualified steel ball, which can accommodate the steel ball 13 of the qualified size, but cannot accommodate the steel ball of larger volume, and a ball placement space is formed between the baffle 10 and the groove, and the steel ball of larger volume cannot be placed in the ball placement space. The steel ball is transmitted by the rotation of the screw rod 2 around the axis, so that the steel ball is Figure 3 The spiral rod 2 can play two roles: first, transport the steel balls 13; second, screen out unqualified large steel balls, including steel balls with unqualified roundness. As mentioned above, Figure 1 The ball screening machine 1 can screen out unqualified small steel balls, and the spiral rod 2 can screen out unqualified large steel balls. Therefore, the ball screening machine 1 cooperates with the spiral rod 2, and steel balls with unqualified volumes cannot pass through the ball screening machine 1 and the spiral rod 2 at the same time, thereby realizing the screening of steel ball sizes.

[0047] like Figure 1 , the end of the spiral rod 2 (i.e. Figure 1 A weighing mechanism is arranged at the middle right end, and the weighing mechanism in this example is a high-precision electronic scale 3, and the high-precision electronic scale 3 is used to weigh the steel ball. The weighing mechanism can be set not only as a high-precision electronic scale 3, but also as other conventional devices capable of weighing.

[0048] like Figure 1After weighing, the steel ball enters the conveyor belt 4. The conveyor belt 4 is docked at the ball outlet of the weighing mechanism. Due to the pushing effect of the adjacent steel balls, the steel balls can fall from the high-precision electronic scale 3 into the conveyor belt 4.

[0049] like Figure 1 ,for Figure 1 In the top view, the conveyor belt 4 transports the steel balls to the right. A plurality of ball pushers 6 are arranged on the side of the conveying direction of the conveyor belt 4. Corresponding to the ball pushers 6, a receiving port 7 is arranged on the opposite side of the conveyor belt 4, and the ball pushers 6 push the steel balls on the conveyor belt 4 into the receiving port 7. The receiving port 7 can be connected to a packaging bag, so that the steel balls fall into the packaging bag for packaging.

[0050] like Figure 2 , multiple ball pushing machines 6 work together, for example, at the beginning, only the first ball pushing machine 6 on the left side moves, and the other two ball pushing machines 6 do not move. When the total weight of the packaging bag corresponding to the first ball pushing machine 6 on the left side reaches the set value, the ball pushing machine 6 does not move, and the adjacent ball pushing machine 6 on the right side starts, so that the steel ball passes over the first receiving port 7 on the left side and enters the middle receiving port 7, and so on.

[0051] like Figure 1 The side of the spiral rod 2 is also provided with an ultrasonic detection mechanism 11, which is used to detect surface defects of the steel ball. The ultrasonic detection mechanism 11 is connected to the ball pusher 6 by signal. When the ultrasonic detection mechanism 11 detects that the surface of the steel ball is unqualified, the ball pusher 6 does not operate. Figure 2 The end (right end) of the conveyor belt 4 is provided with a waste ball receiving frame 5. When the ball pushers 6 are not in operation, the steel balls will fall into the waste ball receiving frame 5 and be collected. The aforementioned high-precision electronic scale 3 is also connected to the ball pusher 6 by signal. When the high-precision electronic scale 3 weighs the steel ball and finds that the weight is unqualified, the signal is transmitted to the ball pusher 6. When the steel ball is transmitted on the conveyor belt 4, the ball pushers 6 are not in operation, so that the steel ball with unqualified weight falls into the waste ball receiving frame 5 and is collected.

[0052] like Figure 1 A light sensing testing mechanism 14 is also provided on the side of the spiral rod 2. The light sensing testing mechanism 14 is used to detect the reflection of the surface of the steel ball 13 to judge the surface quality of the steel ball 13, thereby further checking the quality of the steel ball. The light sensing testing mechanism 14 can also be connected to the ball pusher 6 by signal, so as to realize that the unqualified steel balls detected by the light sensing testing mechanism 14 are sent to the waste ball receiving frame 5.

[0053] In summary, the steel ball packaging line of this example screens out unqualified small steel balls through the ball screening machine 1, screens out unqualified large steel balls through the spiral rod 2, and steel balls with unqualified roundness can also be screened out by the spiral rod 2, the surface defects of the steel balls are detected by the ultrasonic detection mechanism 11, the steel balls are weighed by the high-precision electronic scale 3, and the steel balls are pushed into different packaging bags for packaging through the cooperation of the conveyor belt 4 and the ball pusher 6. Automated steel ball packaging is achieved.

[0054] The beneficial effects are:

[0055] 1. Replacing manpower with machinery and equipment can reduce the workload of workers;

[0056] 2. Improve the automation level of the production line, eliminate the uncertainty of manual labor, and improve packaging efficiency;

[0057] 3. Reduce the quality error of each bag of product and make product packaging more standardized;

[0058] 4. Reducing the number of workers required on the packaging line can reduce labor costs in the long run.

They cannot be used to limit the protection scope of the present invention.
