[0027] The following further describes in detail the specific embodiments of the present utility model with reference to the accompanying drawings.

[0028] As Figure 1 shown, a resin feeding assembly for preventing material shortage of the present utility model includes a vibrating bowl 1, a feeding induction mechanism 2, a dust discharging mechanism 3, and a resin feeding docking mechanism 4;

[0029] As Figure 2 shown, the feeding induction mechanism 2 includes a connecting plate 21, a paddle 23, a positioning plate 22, and a sensing member 24; the connecting plate 21 is located above the vibrating bowl 1; the positioning plate 22 is obliquely arranged at the end of the connecting plate 21, the paddle 23 is vertically connected to the positioning plate 22, the paddle 23 is located on one side of the sensing member 24, and the bottom edge of the positioning plate 22 is closely attached to the paddle 23;

[0030] The paddle 23 extends into the materials in the vibrating bowl 1, and each resin particle collides with the bottom of the paddle 23, causing the paddle 23 to rotate within a small range with the bottom edge of the closely attached positioning plate 22 as the fulcrum. The top of the paddle 23 continuously contacts the sensing member 24. The sensing member 24 is an existing touch sensor. When there are materials near the paddle 23, when the paddle 23 contacts the sensing member 24, a capacitive coupling is generated between the paddle 23 and the sensing member 24, thereby changing the capacitance value of the sensing member 24. By detecting the change in the capacitance value, the touch sensor can obtain a touch signal and convert it into a digital or analog signal and output it to the terminal; when there are no materials near the paddle 23, the paddle 23 is in the initial state, that is, the paddle 23 is not in contact with the sensing member 24. At this time, the terminal receives the information, which is convenient for the administrator to timely control the feeding information and replenish the materials in time to avoid material shortage in the vibrating bowl 1.

[0031] The paddle 23 is vertically provided with a first adjustment groove 231. The first fastener 232 passes through the first adjustment groove 231 to connect the paddle 23 to the positioning plate 22. Different positions of the first adjustment groove 231 can be selected to connect the paddle 23, thereby adjusting the height of the paddle 23. According to resins of different sizes or different feeding speeds, the distance between the paddle 23 and the bottom of the vibrating disk 1 is changed, so as to adjust the depth of the paddle 23 extending into the resin pile. When the preset minimum amount is reached in the disk, it is fed back to the terminal through the sensing member 24.

[0032] The feeding induction mechanism 2 further includes a fixed column 25 and a second fastener 251. The connecting plate 21 is provided with a second adjustment groove 211. The second fastener 251 passes through the second adjustment groove 211 to detachably fix the connecting plate 21 to the fixed column 25. The lateral position of the paddle 23 can be adjusted as needed by selecting different fixing positions of the second adjustment groove 211.

[0033] As Figure 3 shown, the side wall of the vibrating disk 1 is provided with a chip discharge port 11. The dust discharge mechanism 3 includes a baffle 31 and a diversion plate 32. The baffle 31 is connected to the chip discharge port 11, and the diversion plate 32 is inclined and arranged below the baffle 31;

[0034] The resin continuously moves upward along the steps with the continuous vibration of each vibrating disk 1. The dust carried by the resin is shaken out from the chip discharge port 11 with the vibration of the disk body. The baffle 31 plays a role in blocking the resin to prevent the resin from being shaken out of the disk body. The dust is discharged from below the baffle 31 and is uniformly collected along the inclined diversion plate 32.

[0035] Baffles 35 are provided on both sides of the diversion plate 32 to prevent the dust on the diversion plate 32 from flying out from both sides of the plate body due to vibration.

[0036] The baffle 31 is vertically provided with a third adjustment groove 33. The third fastener 34 passes through the third adjustment groove 33 to connect the baffle 31 to the vibrating disk 1. The height of the baffle 31 can be adjusted according to resins of different sizes to meet the baffle requirements of resins of different sizes.

[0037] As Figure 4 shown, the top of the vibrating disk 1 is provided with a discharge port 12. The resin is transmitted from the discharge port 12. A baffle bar 121 is provided above the discharge port 12 to block the resin at the position of the discharge port 12 and prevent the resin from jumping out of the disk.

[0038] The resin feeding docking mechanism 4 includes a transfer table 41 and a limit plate 42; a transfer table 41 is provided at the discharge port 12, a partition plate 411 is provided on the side wall of the transfer table 41, and a limit plate 42 is provided above the transfer table 41. The transfer table 41 serves to connect the vibrating disk 1 and the feed inlet of the subsequent equipment. The resin at the discharge port 12 is transferred from the transfer table 41 to the subsequent equipment under vibration. The partition plate 411 prevents the resin on the transfer table 41 from falling out from the side, and the partition plate 411 prevents the resin from jumping out.

[0039] The vibrating disk 1 is provided with a fixing block 45, the limit plate 42 is provided with an adjusting plate 43, the adjusting plate 43 is provided with a fourth adjusting groove 43, and a fourth fastener 44 passes through the fourth adjusting groove 43 to connect the adjusting plate 43 to the fixing block 45. By selecting different installation positions of the fourth adjusting groove 43, the height of the limit plate 42 can be adjusted, so as to adjust the limit height according to resins of different sizes.

[0040] A feeding mechanism 5 is provided above the vibrating disk 1. The feeding mechanism 5 includes a feeding funnel 51, a transmission member 53, and a plug board 54. A slot 511 is provided horizontally on the feeding funnel 51, and the plug board 54 is located in the slot 511 and is connected to the transmission member 53. When the feeding induction mechanism 2 monitors the inventory information at the bottom of the disk in real time, the terminal sends an instruction to the transmission member 53 according to the information. When the vibrating disk 1 is short of materials, the transmission member 53 can be an existing cylinder assembly. After receiving the instruction, the transmission member 53 moves the slot 511 away, and the resin in the feeding funnel 51 falls into the vibrating disk 1. Subsequently, the transmission member 53 resets the slot 511 according to the program setting to block the remaining materials in the feeding funnel 51 again, realizing automatic feeding.

[0041] A baffle 52 is provided on the side of the discharge port of the feeding funnel 51. The baffle 52 can block the resin that falls rapidly, avoiding the resin from flying out of the disk when it falls rapidly.

[0042] For a resin feeding assembly that prevents material shortage of the present utility model, the resins move upward one by one along the steps from the bottom of the disk following the vibration of the vibrating disk 1. The paddle 23 extends into the resin pile of the vibrating disk 1 to monitor the minimum inventory of the vibrating disk 1 in real time. When the bottom of the paddle 23 cannot touch the resin, the sensing member 24 sends a signal to the terminal, enabling the manager to timely obtain the material shortage information. Among them, during the movement of the resins, the dust can be discharged from the dust discharge mechanism 3 and transmitted out of the vibrating disk 1 from the resin feeding docking mechanism 4.

[0043] The preferred embodiments of the present utility model have been specifically described above, but the present utility model is not limited to the described embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present utility model, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
