In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0035] See also Figures 1 to 6 The present embodiment provides a betel nut feeding device, which is used to supply betel nuts to a betel nut bagging device. In the present embodiment, the betel nut feeding device includes a first conveyor line 1, a first unloading mechanism 2, a sorting mechanism 3, a second conveyor line 4 and a second unloading mechanism 5, wherein the first unloading mechanism 2 is installed at the upstream end of the first conveyor line 1, and includes a first driving member 21 and a flip module 22, the first driving member 21 is configured to lift a supply barrel 71 containing betel nuts, and the flip module 22 is configured to flip the lifted supply barrel 71, The betel nuts in the supply barrel 71 are poured onto the first conveyor line 1. The betel nuts poured onto the first conveyor line 1 can be conveyed along the first conveyor line 1. A sorting station is provided on the first conveyor line 1. The sorting mechanism 3 is provided at the sorting station and is configured to sort the betel nuts. It is worth noting that the sorting mechanism 3 in this embodiment is an X-ray sorting machine, so that the betel nuts can be sorted. Of course, in other optional embodiments, the sorting mechanism 3 can also be a visual sorting machine or other machine that can realize automatic sorting, and no specific restrictions are made in this embodiment. Since the specific structure and working process of the sorting mechanism 3 are both prior art, no further description is made in this embodiment.

[0036] Based on the above, a first discharging channel 11 and a second discharging channel 12 are provided on the downstream side of the first conveyor line 1. Good quality betel nuts can be conveyed to the first collecting barrel 72 through the first discharging channel 11, and defective betel nuts can be sent out through the second discharging channel 12. It can be understood that a second collecting barrel (not shown in the figure) can be placed at the downstream end of the second discharging channel 12 to collect defective betel nuts.

[0037] It can be understood that the second collecting bucket can also collect impurities mixed in the betel nut sorted out by the sorting mechanism 3.

[0038] Furthermore, the second conveyor line 4 is configured to convey the first collecting barrel 72 to the unloading station, the second unloading mechanism 5 is arranged at the unloading station, and is configured to pour the betel nuts in the first collecting barrel 72 to the betel nut bagging device, thereby realizing automatic loading of betel nuts.

[0039] Based on the above, the betel nut feeding device in this embodiment can realize the automatic feeding of betel nuts, and can automatically sort the betel nuts during the feeding process. The whole process saves time and labor, thereby improving the production efficiency of betel nut packaging.

[0040] Preferably, the first unloading mechanism 2 also includes a base frame 23, the first driving member 21 is installed on the base frame 23, the flip module 22 includes a first mounting plate 221, a second mounting plate 222 and a roller 223, and a first clamp block 2211 and a second clamp block 2212 are installed on one side of the first mounting plate 221, and the first clamp block 2211 and the second clamp block 2212 can embrace the outer periphery of the supply barrel 71. Specifically, the first clamp block 2211 and the second clamp block 2212 are arranged opposite to each other, and the first clamp block 2211 and the second clamp block 2212 can move relative to or away from each other, so as to clamp or release the supply barrel 71.

[0041] Furthermore, a crank 2213 is provided on the first mounting plate 221, the top end of the crank 2213 is bent toward a side away from the first clamp 2211 and the second clamp 2212, and the crank 2213 is rotatably connected to the second mounting plate 222 through the first rotating shaft 2214. The first driving member 21 can drive the second mounting plate 222 to rise and fall in the vertical direction, and drive the first mounting plate 221 to rise and fall in the vertical direction through the crank 2213. The roller 223 is arranged on a moving path of the bent portion of the crank 2213 that rises and falls in the vertical direction, and the axis of the first rotating shaft 2214 is parallel to the axis of the roller 223. When the first driving member 21 drives the second mounting plate 222 to rise in the vertical direction to lift the supply barrel 71 containing betel nuts, the bent portion of the crank 2213 can rise in the vertical direction until it abuts against the roller 223. Thereafter, the second mounting plate 222 continues to rise, and the crank 2213 drives the first mounting plate 221 to rotate around the axis of the first rotating shaft 2214 under the obstruction of the roller 223. Accordingly, the roller 223 slides relative to the crank 2213 along the curved surface of the crank 2213, thereby causing the supply barrel 71 to flip, and then pouring the betel nuts onto the first conveyor line 1.

[0042] In addition, when the first mounting plate 221 is lifted and lowered in the vertical direction, the side of the first mounting plate 221 away from the first clamping block 2211 and the second clamping block 2212 abuts against the base frame 23, thereby preventing the supply barrel 71 from tipping downward due to its own gravity when rising in the vertical direction.

[0043] Based on the above, when the first driving member 21 drives the second mounting plate 222 to rise in the vertical direction to lift the supply barrel 71 containing betel nuts, under the action of the gravity of the supply barrel 71, the first mounting plate 221 abuts against the base frame 23 on one side away from the first clamping block 2211 and the second clamping block 2212. When the crank 2213 abuts against the roller 223, the second mounting plate 222 continues to rise, and the crank 2213 begins to rotate around the axis of the first rotating shaft 2214, thereby driving the supply barrel 71 to flip upward, and then pouring the betel nuts onto the first conveyor line 1.

[0044] In this embodiment, the first driving member 21 drives the second mounting plate 222 to rise and fall in the vertical direction through the transmission chain. During the process of the first mounting plate 221 rising and falling in the vertical direction, the side of the first mounting plate 221 away from the first clamping block 2211 and the second clamping block 2212 abuts against the second mounting plate 222. The second mounting plate 222 is provided with an abutting block 2221. The side of the abutting block 2221 away from the first mounting plate 221 abuts against the base frame 23, so that the second mounting plate 222 can be stably raised and lowered in the vertical direction on the one hand, and the supply barrel 71 can be prevented from falling down due to its own gravity during the process of rising in the vertical direction on the other hand. Of course, in other optional embodiments, the first driving member 21 can also drive the second mounting plate 222 to rise and fall in the vertical direction through other transmission methods, and this embodiment does not specifically limit this. In addition, in other optional embodiments, an abutting structure that abuts against the base frame 23 can be directly provided on the first mounting plate 221 to prevent the supply barrel 71 from tipping downward due to its own gravity during the vertical ascending process. This is not specifically limited in the present embodiment.

[0045] It is worth noting that the first driving member 21 can be a driving structure such as a stepping motor or a servo motor, and there is no specific limitation on this in this embodiment.

[0046] In addition to the first clamping block 2211 and the second clamping block 2212, a pressing block 2215 is also installed on the first mounting plate 221. When the supply barrel 71 is embraced between the first clamping block 2211 and the second clamping block 2212, the pressing block 2215 presses on the top of the supply barrel 71, thereby preventing the supply barrel 71 from falling from between the first clamping block 2211 and the second clamping block 2212 during the process of flipping the supply barrel 71 to pour the betel nut onto the first conveyor line 1.

[0047] It can be understood that in this embodiment, the first clamping block 2211 and the second clamping block 2212 are both provided with a pressing block 2215 , and during the relative or opposite movement of the first clamping block 2211 and the second clamping block 2212 , the two pressing blocks 2215 also move relative or opposite to each other.

[0048] Based on the above, in the present embodiment, the first clamp 2211 and the second clamp 2212 are respectively provided with a first driving structure 2216 and a second driving structure 2217. The first driving structure 2216 is used to drive the first clamp 2211 to move toward or away from the second clamp 2212, and the second driving structure 2217 is used to drive the second clamp 2212 to move toward or away from the first clamp 2211. The first driving structure 2216 and the second driving structure 2217 can both be selected as driving structures such as cylinders, electric cylinders or linear motors, and there is no specific limitation on this in the present embodiment.

[0049] Furthermore, a first limit block 231 and a second limit block 232 are installed on the base frame 23, and the first limit block 231 and the second limit block 232 are spaced apart in the vertical direction. The second mounting plate 222 can descend in the vertical direction to abut against the first limit block 231, and can rise in the vertical direction to abut against the second limit block 232, thereby limiting the stroke of the second mounting plate 222. In addition, the first limit block 231 can also ensure that the first clamping block 2211 and the second clamping block 2212 stably clamp the supply barrel 71 below the base frame 23.

[0050] Preferably, the first conveyor line 1 includes a first line body 13, a second line body 14 and a second driving member 15. A screen 131 is installed on the upstream side of the first line body 13. The flip module 22 can pour the betel nuts in the supply barrel 71 onto the screen 131. The second driving member 15 is configured to shake the first line body 13. In this embodiment, the second driving member 15 is a shaking motor. Since the first line body 13 can shake, on the one hand, the betel nuts falling on the screen 131 can be shaken by the screen 13. 1 is shaken and transported forward. On the other hand, the screen 131 can perform preliminary sorting of the betel nuts to screen out impurities carried in the betel nuts poured onto the screen 131 and screen out smaller betel nuts. Specifically, impurities and smaller betel nuts can fall through the pores of the screen 131. The second line body 14 is connected to the downstream end of the first line body 13. The sorting station is set on the second line body 14. The sorting mechanism 3 can perform secondary sorting on the betel nuts transported from the first line body 13 to the second line body 14.

[0051] Based on the above contents, the betel nut feeding device also includes a first funnel 61, which is installed on the upstream side of the first conveyor line 1. The flip module 22 can pour the betel nuts in the supply barrel 71 into the feed port of the first funnel 61. The discharge port of the first funnel 61 is opposite to the first conveyor line 1. The first funnel 61 is used to gather the betel nuts poured out from the supply barrel 71, so as to ensure that all the betel nuts can be poured onto the first conveyor line 1 without spilling.

[0052] In addition, a guide plate 611 is installed on the side of the first funnel 61 close to the first unloading mechanism 2, and the end of the guide plate 611 close to the first funnel 61 is connected to the feed port, and the end of the guide plate 611 away from the first funnel 61 is higher than the end of the guide plate 611 close to the first funnel 61, thereby facilitating the entry of betel nut into the first funnel 61.

[0053] It can be understood that baffles 6111 are installed on both sides of the guide plate 611 to further prevent betel nuts from spilling.

[0054] It is worth noting that a second funnel 62 is installed below the screen 131, and a third collecting bucket (not shown in the figure) can be placed at the outlet of the second funnel 62 to collect impurities.

[0055] Furthermore, the second conveyor line 4 includes a third line body 41 and a fourth line body 42, the third line body 41 is arranged at the downstream end of the first discharge channel 11, and the fourth line body 42 is configured to circulate and convey the first collecting barrel 72 between the third line body 41 and the unloading station, thereby conveying the first collecting barrel 72 filled with betel nuts to the unloading station, and sending the empty first collecting barrel 72 back to the third line body 41.

[0056] It should be noted that the fourth line body 42 can be formed by combining a horizontal line body and a vertical line body. Since the specific structure and conveying process of the fourth line body 42 are both existing technologies, they will not be described in detail in this embodiment.

[0057] Furthermore, the second unloading mechanism 5 includes a frame 51, a third mounting plate 52 and a third driving member 53. The third mounting plate 52 is installed with a third clamp 521 and a fourth clamp 522. The third clamp 521 and the fourth clamp 522 can embrace the outer periphery of the first collecting barrel 72. Specifically, the third clamp 521 and the fourth clamp 522 are arranged relative to each other, and the third clamp 521 and the fourth clamp 522 can move relative to or away from each other, so as to clamp or release the first collecting barrel 72.

[0058] The third mounting plate 52 is rotatably connected to the frame 51 via the second rotating shaft 523, and the third driving member 53 is configured to drive the third mounting plate 52 to rotate around the axis of the second rotating shaft 523, thereby flipping the first collecting barrel 72, and then pouring the betel nuts in the first collecting barrel 72 into the betel nut bagging device.

[0059] It is worth noting that the third driving member 53 can be a driving structure such as a stepping motor or a servo motor, and there is no specific limitation on this in this embodiment.

[0060] Based on the above, in the present embodiment, the third clamp 521 and the fourth clamp 522 are respectively provided with a third driving structure (not shown in the figure) and a fourth driving structure (not shown in the figure). The third driving structure is used to drive the third clamp 521 to move toward or away from the fourth clamp 522, and the fourth driving structure is used to drive the fourth clamp 522 to move toward or away from the third clamp 521. The third driving structure and the fourth driving structure can both be selected as driving structures such as cylinders, electric cylinders or linear motors, and there is no specific limitation on this in the present embodiment.

[0061] In addition, the second unloading mechanism 5 also includes a positioning block 54, and the first collecting barrel 72 can be conveyed along the second conveying line 4 to abut against the positioning block 54, thereby positioning the first collecting barrel 72, thereby ensuring that the third clamping block 521 and the fourth clamping block 522 can accurately clamp the first collecting barrel 72.
