[0030] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As Figures 1 to 6 shown, a multi-channel lifting and feeding single machine provided by the present utility model includes a lifting and feeding mechanism 1, a first-stage straight vibration channel 2, a second-stage straight vibration channel 3, and a multi-channel blanking device 4. The lifting and feeding mechanism 1 lifts and transports materials to the channel through a conveying chain plate; both the first-stage straight vibration channel 2 and the second-stage straight vibration channel 3 are vibrationally connected to a straight vibrator, and the materials are pushed forward by the vibration force; the multi-channel blanking device 4 realizes the storage and blanking of materials.

[0032] Specifically, as Figure 1 and Figure 2 shown, the first-stage straight vibration channel 2 is arranged to gradually widen from narrow to wide. The narrow end of the first-stage straight vibration channel 2 is connected to the lifting and feeding mechanism 1, and its wide end is bifurcated with a plurality of feeding channels 21. The materials are lifted and transported by the lifting and feeding mechanism 1 to the narrow end of the first-stage straight vibration channel 2, and then spread from the narrow end of the first-stage straight vibration channel 2 to each feeding channel 21 at the wide end. The first-stage straight vibration channel 2 is arranged to gradually widen from narrow to wide to achieve multi-channel feeding.

[0033] As Figure 2 shown, the second-stage straight vibration channel 3 includes a plurality of screening channels 32 and a feeding compensation channel 31. The feeding compensation channel 31 is located at the middle position of the plurality of screening channels 32. The plurality of feeding channels 21 are respectively aligned and connected to the feeding compensation channel 31 and the plurality of screening channels 32 one by one, and the materials in each feeding channel 21 can be vibrationally fed to the corresponding screening channel 32 or feeding compensation channel 31 to achieve multi-channel screening and feeding.

[0034] In this embodiment, as Figure 2 shown, the second-stage straight vibration channel 3 includes four screening channels 32 and one feeding compensation channel 31. Two screening channels 32 are arranged on both sides of the feeding compensation channel 31. The two screening channels 32 on the same side are integrally designed, that is, as Figure 2 and Figure 3 shown, the two screening channels 32 are welded together and share the same straight vibrator for vibration feeding, and then vibration feeding compensation is carried out through the feeding compensation channel 31. The feeding compensation channel 31 is separately arranged and uses a separate straight vibrator alone to avoid resonance between the feeding compensation channel 31 and the left and right screening channels 32.

[0035] As Figures 3 to 6As shown in the figure, the multi-channel blanking device 4 includes a first-level feeding mechanism 41, a second-level multi-channel storage mechanism 42, and a third-level multi-channel blanking mechanism 43 arranged from top to bottom. The first-level feeding mechanism 41 is located in the middle at the top of the second-level multi-channel storage mechanism 42. The lower part of the first-level feeding mechanism 41 divides the second-level multi-channel storage mechanism 42 into a left channel and a right channel by arranging an intermediate partition plate 45, and also divides the third-level multi-channel blanking mechanism 43 into a left channel and a right channel;

[0036] As Figure 1 shown in the figure, the feeding channel 31 is connected to the first-level feeding mechanism 41. A plurality of screening channels 32 on the left side of the feeding channel 31 are respectively connected and communicated with the left channels of the second-level multi-channel storage mechanism 42 and the third-level multi-channel blanking mechanism 43. A plurality of screening channels 32 on the right side of the feeding channel 31 are respectively connected and communicated with the right channels of the second-level multi-channel storage mechanism 42 and the third-level multi-channel blanking mechanism 43;

[0037] As Figure 5 shown in the figure, the first-level feeding mechanism 41 includes a feeding bin 411, a feeding paddle 412, and a feeding driving mechanism 413. The feeding driving mechanism 413 and the feeding paddle 412 are drivingly connected. The left and right sides of the top of the inner cavity of the feeding bin 411 are provided with limiting side plates 414. The feeding paddle 412 is located in the inner cavity of the feeding bin 411 and rotates between the left and right limiting side plates 414 under the drive of the feeding driving mechanism 413;

[0038] When the feeding paddle 412 approaches the left limiting side plate 414, the feeding bin 411 is sequentially connected and communicated with the right channel of the second-level multi-channel storage mechanism 42 and the right channel of the third-level multi-channel blanking mechanism 43, and the materials on the feeding channel 31 are fed to the right channel through the first-level feeding mechanism 41. When the feeding paddle 412 approaches the right limiting side plate 414, the feeding bin 411 is sequentially connected and communicated with the left channel of the second-level multi-channel storage mechanism 42 and the left channel of the third-level multi-channel blanking mechanism 43, and the materials on the feeding channel 31 are fed to the left channel through the first-level feeding mechanism 41;

[0039] As Figure 5 and Figure 6 shown in the figure, the second-level multi-channel storage mechanism 42 and the third-level multi-channel blanking mechanism 43 are both provided with a rotating paddle and a rotating driving mechanism in the left and right channels. In the second-level multi-channel storage mechanism 42, the rotating paddle plays a role of storing materials and discharging materials when the materials are replenished. In the third-level multi-channel blanking mechanism 43, the rotating paddle plays a role of discharging and feeding materials;

[0040] As Figure 1 and Figure 4As shown, the multi-channel blanking device 4 is provided with a plurality of material sensors 44 at the feed inlet. The plurality of material sensors 44 are respectively arranged in one-to-one correspondence with the replenishment flow channel 31 and the plurality of screening flow channels 32 to respectively identify the situation of the materials on each screening flow channel 32 and the replenishment flow channel 31 entering the multi-channel blanking device 4;

[0041] During specific operation, the materials are fed by the lifting and feeding mechanism 1 to the narrow end of the first-stage straight vibration flow channel 2. The materials advance to the plurality of feed flow channels 21 under the vibration of the straight vibrator, and then enter the plurality of screening flow channels 32 and the replenishment flow channel 31 for screening, and advance forward under the vibration of the straight vibrator to enter the multi-channel blanking device 4. The material sensors 44 at the feed inlet of the multi-channel blanking device 4 identify the materials entering the second-stage multi-channel storage mechanism 42 from each screening flow channel 32. When it is identified that the quantity entering the left channel of the second-stage multi-channel storage mechanism 42 has not reached the set quantity, a signal will be sent to make the replenishment driving mechanism 413 drive the replenishment paddle 412 to rotate to the right limit side plate 414. At this time, the replenishment bin 411 is communicated with the left channel of the second-stage multi-channel storage mechanism 42, and the materials on the replenishment flow channel 31 enter the left channel of the second-stage multi-channel storage mechanism 42 for replenishment. When it is identified that the quantity entering the right channel of the second-stage multi-channel storage mechanism 42 has not reached the set quantity, the right channel is replenished in the same way; when the left and right channels of the second-stage multi-channel storage mechanism 42 are replenished with materials, the rotating paddle of the second-stage multi-channel storage mechanism 42 will rotate to make the materials fall to the third-stage multi-channel blanking mechanism 43, and then the materials are lowered to the hopper on the circulation line through the third-stage multi-channel blanking mechanism 43;

[0042] The feeding efficiency can be greatly improved through the multi-channel feeding method; in addition, the replenishment flow channel 31 is provided to identify and replenish the material shortage phenomenon while feeding, further improving the feeding speed; and the replenishment flow channel 31 is arranged in the middle position of the plurality of screening flow channels 32. Each time replenishment is carried out, it is only necessary to identify whether there is a shortage of materials in one side of the screening flow channel 32, and only one side channel of the second-stage multi-channel storage mechanism 42 needs to be replenished. Compared with the replenishment flow channel 31 arranged on one side, its identification speed is faster and the replenishment speed is faster, further improving the feeding speed, so as to avoid affecting the packaging speed of the circulation line.

[0043] Furthermore, as Figure 2 shown, a flow channel partition 22 is provided between every two adjacent feed flow channels 21. The setting of the flow channel partition 22 makes the materials in each feed flow channel 21 evenly distributed, so that the feeding is uniform; the front end of each flow channel partition 22 is inclined and guided to play a role in guiding the feeding of the materials accumulated here.

[0044] Furthermore, as Figure 2As shown, feed hoppers 23 are provided at the ends of multiple feed channels 21. The nozzles of the feed hoppers 23 are inclined downward, which plays a role in guiding the feed. And the downward direction is determined according to the position of the screening channel 32, so that the nozzles of the feed hoppers 23 are respectively aligned and connected with the front ends of multiple screening channels 32, ensuring that the materials are fed into the corresponding screening channels 32 accurately, and avoiding phenomena such as material blockage, material dropping, and material jamming caused by chaotic feeding.

[0045] Further, as Figure 2 shown, there are margins 24 between the two middle feed hoppers 23 and the middle channel partition 22. The margins 24 are aligned and connected with the replenishing channel 31. The materials in the first-stage straight vibration channel 2 enter the replenishing channel 31 through the margins 24, eliminating the need to set up an additional feed channel 21, reducing costs and saving space, and enabling the screening channel 32 and the replenishing channel 31 to be arranged compactly, avoiding serious material accumulation between the channels.

[0046] Further, as Figure 2 shown, an adjusting plate 311 for adjusting the size of the channel is provided on the replenishing channel 31. The size of the rear-end channel of the replenishing channel 31 is adjusted through the adjusting plate 311 to screen the materials entering the rear end, avoiding excessive materials on the rear-end channel of the replenishing channel 31 and affecting subsequent replenishment.

[0047] Further, as Figure 3 shown, a baffle 321 is inclined between the front ends of multiple screening channels 32 on the same side. The setting of the baffle 321 can prevent materials from accumulating between the screening channels 32 on the same side, and the inclined setting of the baffle 321 can guide the materials falling on the baffle 321 into the main channel.

[0048] Further, as Figure 3 shown, for the integrated screening channels 32 on the same side, there are baffles surrounding them on all sides, effectively preventing materials from accumulating between the screening channels 32 on the same side.

[0049] Further, as Figure 3 shown, a discharge port 322 is provided between the rear ends of multiple screening channels 32 on the same side. If materials accumulate between the screening channels 32 on the same side, the materials can also be discharged from the discharge port 322 through the vibration of the straight vibrator.

[0050] In summary, the feeding efficiency of the present utility model is greatly improved through the multi-channel feeding method. In addition, a replenishing flow channel 31 is provided to identify and replenish the material shortage while feeding, further improving the feeding speed. And the replenishing flow channel 31 is arranged at the middle position of multiple screening flow channels 32. Each time of replenishing, only need to identify whether there is a material shortage in one side of the screening flow channel 32, and only need to replenish one side channel of the secondary multi-channel storage mechanism 42. Compared with the replenishing flow channel 31 arranged on one side, its identification speed is faster and the replenishing speed is faster, further improving the feeding speed, thereby avoiding affecting the packaging speed of the circulation line.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
