[0029] EMBODIMENT

[0030] Please refer to Figures 1 to 11 It is shown that the present embodiment provides a folding medicine hopper for medicine delivery, which comprises a rear section hopper 1 and a front section hopper 2; the rear section hopper 1 comprises a first bottom plate 11 inclined from top to bottom rearward and first side plates 12 located on the left and right sides of the first bottom plate 11; the front section hopper 2 comprises a second bottom plate 21 and second side plates 22 located on the left and right sides of the second bottom plate 21 outside the first side plates 12; the front position of the bottom side of the first bottom plate 11 is connected with the rear position of the bottom side of the second bottom plate through a hinge 13, so as to make the front section hopper 2 have a degree of freedom of forward and backward flipping relative to the rear section hopper 1, and make the folding medicine hopper switch between the folded state and the unfolded state.

[0031] In the present embodiment, in order to ensure the strength of the two first side plates 12, the rear section hopper 1 further comprises an upper connecting plate 15 (as shown in Figure 2 and The two ends of the upper connecting plate 15 are respectively connected with the top sides of the two first side plates 12.

[0032] Figures 2 to 4 In the present embodiment, a front flipping limiting position and a rear flipping limiting position are further provided between the rear section hopper 1 and the front section hopper 2 to limit the flipping angle of the front section hopper; specifically as shown in As shown, the front turning limiting position is formed by the second side plate 22 extending downward, and the bottom side of the front hopper 2 is provided with a pad 14 below the hinge. When the front hopper 2 is turned forward by a certain angle, the rear corner 26 of the bottom end of the second side plate 22 will touch the pad 14, forming the front turning limiting position. As for the rear turning limiting position, a small part of the rear end of the second bottom plate 21 is below the front end of the first bottom plate 11, which can effectively limit the turning angle of the front hopper.

[0033] In the embodiment, the folding state is that the front hopper 2 is turned backward to the rear turning limiting position, at which the second bottom plate is in a generally horizontal state. At this time, it is the receiving medicine state (as shown in Figure 3 and Figure 10 As shown, the second bottom plate in the horizontal state can effectively buffer the medicine sliding down from the first bottom plate; the unfolding state is that the front hopper 2 is turned forward to the front turning limiting position, at which the second bottom plate is in a rear-up-to-front-down inclined state, generally parallel to the first bottom plate. At this time, it is the pre-dispensing medicine state (as shown in Figure 4 As shown, the medicine slides to the front end of the second bottom plate.

[0034] In the embodiment, when the bottom side of the folding hopper has a lower barrier (for example, the bottom plate of the box described later), the front hopper will be blocked by the barrier and turned backward to the folding state. When the bottom side of the folding hopper does not have a barrier, the front hopper will be turned forward under the influence of gravity to the unfolding state.

[0035] In the embodiment, in order to avoid the turning speed of the front hopper being too fast, a friction plate is further arranged between the second side plate of the front hopper and the first side plate of the rear hopper.

[0036] Referring again to Figures 1 to 3 As shown, the bottom side of the front hopper 2 is provided with a roller 23 at a forward position. In order to reduce the friction between the front hopper 2 and the barrier, the roller 23 is arranged to realize rolling friction when contacting the barrier, thereby reducing the loss.

[0037] Referring again to Figures 1 to 6 As shown, the folding hopper further comprises a gate assembly 3; the gate assembly 3 comprises a first gate 31 arranged at the front end of the front hopper 2; the rear end of the first gate 31 is hingedly connected to the front end of the front hopper at a position close to the bottom side; the gate assembly 3 further comprises a gate driving mechanism 32 for driving the first gate 31 to turn forward to open the medicine outlet of the front hopper 2, and for driving the first gate 31 to turn backward to close the medicine outlet of the front hopper 2.

[0040] In the embodiment, in order to avoid that the turning speed of the first gate is too fast, a friction plate is also arranged between the third side plate of the first gate and the second side plate of the front section of the hopper.

[0041] In the embodiment, the first gate 31 can use the first gate plate 311 to open a notch at the position corresponding to the second side plate, and when the first gate 31 is turned forward to the notch and contacts the second side plate, it is in the completely opened state.

[0042] In the embodiment, the gate assembly 3 further comprises a second gate 33, which is arranged at the front end of the front section of the hopper 2 and above the first gate 31; the gate driving mechanism 32 is further used to drive the second gate 31 to move upward, cooperate with the forward turning of the first gate 31, open the medicine discharging port of the front section of the hopper 2, and further used to drive the second gate 31 to move downward, cooperate with the backward turning of the first gate 31, close the medicine discharging port of the front section of the hopper 2.

[0043] In the embodiment, the second gate 33 comprises a second gate plate 331 and a fourth side plate 332 located on the left and right sides of the second gate plate 331; the gate driving mechanism 32 further comprises a second transmission rod 323; one end of the second transmission rod 323 is hingedly connected to a position close to the rear side of the third side plate 312, and the other end is hingedly connected to the fourth side plate 332; the front end of the upper position of the front section hopper 2 is further provided with a front plate 24; the front plate 24 is provided with a sliding rail sliding block assembly 25; the second gate plate 331 is installed at the moving end of the sliding rail sliding block assembly 25; the third side plate 312 is further used to drive the second transmission rod 323 when the third side plate 312 is flipped forward or backward under the cooperation of the rotation of the transmission wheel 321 and the first transmission rod 322, so that the second gate 33 moves up and down along the sliding rail sliding block assembly 25.

[0044] Referring again to Figures 7 to 11 , the embodiment further provides a lifting device, comprising a box body 5; a plurality of basket placing hoppers 51 for placing medicine baskets 6 are arranged in the box body 5; the side of the basket placing hopper 51 is open; the box body 5 is provided with a basket placing window 52 at a position corresponding to the opening of the basket placing hopper 51; a lifting assembly 4 is further arranged in the box body 5 behind the plurality of basket placing hoppers 51; the lifting end of the lifting assembly 4 is installed with the folding hopper.

[0045] As Figure 8 shown, the lifting assembly 4 comprises a vertical sliding frame 41, a vertical track beam 42, and a lifting driving element 43 for driving the vertical sliding frame 41 to move up and down along the vertical track beam 42; the vertical sliding frame 41 serves as the lifting end of the lifting assembly 4.

[0046] As Figure 9 shown, the vertical sliding frame 41 comprises a bracket 411 installed on both sides of the rear section hopper 1 of the folding hopper, and a pulley set 412 installed on the bracket; the pulley set 412 comprises at least a plurality of pulleys matched with the inner side, the rear side and the front side of the vertical track beam 42.

[0047] As Figure 8 and Figure 9 shown, the lifting assembly 4 further comprises synchronous pulleys arranged on the top side and the bottom side of the vertical track beam 42, and a synchronous belt 44 matched with the synchronous pulleys; the top side and the bottom side of the bracket 411 are further provided with synchronous belt fixing members 413, and the two ends of the synchronous belt 44 are fixedly connected to the synchronous belt fixing members 413 in correspondence; the synchronous pulleys are used to receive the rotating power of the lifting driving element 43, drive the synchronous belt 44 to move, and further drive the vertical sliding frame 41 to drive the folding hopper to move up and down along the vertical track beam 42.

[0048] The lifting device of the embodiment, when in use, the bottom side of the box body is the lowest side of the lifting assembly 4, that is, the medicine feeding position; when the folding hopper is lowered to the lowest position, the rollers of the front section of the folding hopper first contact the bottom plate of the box body, the front section of the folding hopper is flipped backward until the backward flipping limit position, at this time, the medicine feeding port of the rear section of the folding hopper is connected with the medicine outlet of the previous device, and the second bottom plate of the front section of the folding hopper is in a generally horizontal state; when the previous device outputs medicine to the folding hopper, the medicine slides from the first bottom plate (inclined from the rear top to the front bottom) to the second bottom plate of the rear section of the folding hopper, and in the horizontal state of the second bottom plate, the medicine is buffered at the second bottom plate to avoid direct impact with the gate assembly. When all the required medicine enters the folding hopper, the lifting assembly drives the folding hopper to rise, when the folding hopper leaves the bottom plate of the box body, the front section of the folding hopper flips forward relative to the rear section of the folding hopper under the action of gravity until the forward flipping limit position, at this time, the second bottom plate of the front section of the folding hopper is generally parallel to the first bottom plate of the rear section of the folding hopper, and the medicine in the folding hopper is also concentrated at the front lower end of the front section of the folding hopper (the position between the second bottom plate and the gate); after the lifting assembly drives the folding hopper to rise to the required medicine basket of the basket placing hopper, the gate driving motor of the folding hopper drives the driving gear to rotate, the transmission wheel is rotated, the transmission wheel eccentrically drives the first transmission rod, and the first transmission rod drives the first gate to flip forward and downward; synchronously, the flipping of the first gate also drives the second gate to move upward along the slide rail block assembly on the front plate through the second transmission rod; in this way, the first gate and the second gate open the medicine outlet of the front section of the folding hopper, at the same time, the first gate plate is also in a generally parallel state with the second bottom plate, and the front end of the first gate plate is connected with the basket placing hopper; the medicine slides into the medicine basket from the front section of the folding hopper, and the medicine feeding is completed; due to the design of the "double-door" of the gate assembly, the first gate plate can be designed to be shorter, and at the same time, the effective capacity of the folding hopper can be ensured, at the same time, the first gate and the second gate can also ensure that the opening of the folding hopper is large enough when the medicine is fed out, and the feeding speed of the folding hopper is not affected; in addition, the shorter design of the first gate plate has a smaller operation space (the space occupied by flipping), so that the distance from the folding hopper to the medicine basket can be designed to be shorter, the stability of the medicine feeding is improved; at the same time, the distance between two adjacent basket placing hoppers can also be designed to be smaller, the space utilization rate of the lifting device is effectively improved, and the capacity of the lifting device is improved.

[0049] The above embodiments should not limit the present application in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present application.
