[0022] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions of the present utility model in conjunction with specific embodiments of the present utility model and the corresponding drawings. Apparently, the described embodiments are only a part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0023] To solve the technical problems in the prior art, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments:

[0024] As Figures 1 to 3 shown, an embodiment of the present utility model discloses a feeding device for both sides of a tablet press, which includes a feeding cylinder 1 and a fixing frame 2. The fixing frame 2 is connected to the feeding cylinder 1. The upper end of the feeding cylinder 1 is provided with a feeding port 11. The lower end of the feeding cylinder 1 is provided with a first discharge port 12 and a second discharge port 13 at intervals. The first discharge port 12 and the second discharge port 13 are respectively communicated with the feeding port 11. The middle part of the lower end of the feeding cylinder 1 is provided with a connecting platform 3. A solid hemisphere 4 and a diversion plate 5 are arranged on the connecting platform 3. The diversion plate 5 is arranged above the solid hemisphere 4. One side of the diversion plate 5 is inclined towards the direction of the first discharge port 12, and the other side of the diversion plate 5 is inclined towards the direction of the second discharge port 13.

[0025] By dividing the outlet of the feeding cylinder 1 into two parts to form the first discharge port 12 and the second discharge port 13, one end of the fixing frame 2 is connected to the feeding cylinder 1. The feeding cylinder 1 is fixed on the tablet press through the fixing frame 2. The first discharge port 12 is docked with one cylinder of the tablet press, and the second discharge port 13 is docked with the other cylinder of the tablet press. In this way, the tablet press with double-sided cylinders can discharge materials from both sides at the same time, which is convenient for operation, and there is no need to observe the discharging situation of a single cylinder all the time when discharging materials.

[0026] Also, by installing a solid hemisphere 4 and a diversion plate 5 on the connecting platform 3 provided in the middle of the lower end of the feeding cylinder 1, the materials falling from the middle of the feeding cylinder 1 can be smoothly diverted and fall into the first discharge port 12 and the second discharge port 13, and will not accumulate on the connecting platform 3 between the first discharge port 12 and the second discharge port 13. One side of the diversion plate 5 is inclined towards the first discharge port 12, and the other side of the diversion plate 5 is inclined towards the second discharge port 13, so that the discharging on both sides is uniform.

[0027] In some embodiments, the diversion plate 5 is in an inverted V shape or an inverted U shape.

[0028] The deflector 5 and the solid hemisphere 4 together form a structure similar to that of a tumbler. During the blanking process, the deflector 5 sways from side to side, and the material falling from the feed inlet 11 of the feed cylinder 1 lands on either side of the deflector 5 and then falls into the first discharge port 12 or the second discharge port 13.

[0029] In some embodiments, a sieve is provided at the feed inlet 11. Preferably, a cross-shaped sieve is selected to sieve out large particles in the material.

[0030] The sieve can be erected at the upper end of the feed cylinder 1 and installed as needed. After the fine material passes through the sieve, it enters the feed cylinder 1 and then flows out through the first discharge port 12 and the second discharge port 13 by diversion. Also, the sieve can be fixedly installed inside the feed cylinder 1. Specifically, the inner wall of the feed cylinder 1 is provided with positioning blocks protruding along the circumferential direction, and the bottom side of the sieve abuts against the positioning blocks.

[0031] In some embodiments, there is an included angle between the first discharge port 12 and the second discharge port 13. The discharge port, the first discharge port 12, and the second discharge port 13 together form a V-shaped shape.

[0032] The size of the included angle between the first discharge port 12 and the second discharge port 13 is specifically adjusted according to the distance between the two side cylinders to ensure that the first discharge port 12 and the second discharge port 13 are respectively docked with the cylinders on the tablet press.

[0033] In some embodiments, a first limiting plate 6 is provided on one side of the connection platform 3, and a second limiting plate 7 is provided on the other side of the connection platform 3. The solid hemisphere 4 is placed between the first limiting plate 6 and the second limiting plate 7.

[0034] In the static state, the outer periphery of the solid hemisphere 4 does not come into contact with the first limiting plate 6 and the second limiting plate 7, and the first limiting plate 6 and the second limiting plate 7 position the installation position of the solid hemisphere 4. When the solid hemisphere 4 sways from side to side, the material on the deflector 5 is poured into the first discharge port 12 and the second discharge port 13, and the first limiting plate 6 and the second limiting plate 7 can prevent the solid hemisphere 4 from tilting too far to the left or too far to the right.

[0035] In some embodiments, at least two solid hemispheres 4 are provided at intervals on the connection platform 3. The center of gravity direction of the deflector 5 is the same as that of the solid hemisphere 4.

[0036] In some embodiments, the fixing frame 2 is a T-shaped bracket, and the fixing frame 2 is detachably installed on the tablet press. The feed cylinder 1 is fixedly installed on the tablet press through the T-shaped fixing frame 2. Preferably, the fixing frame 2 is connected to the outside of the connection platform 3.

[0037] Further, the vertical section of the fixing frame 2 is connected to the feeding cylinder 1. A plurality of suction cups 8 are provided on one side of the horizontal section of the fixing frame 2. One end of the suction cup 8 is in close contact with the tablet press, and the other end of the suction cup 8 passes through the other side of the horizontal section of the fixing frame 2 and is connected to a vacuum pump through a trachea.

[0038] The suction cup 8 on one side of the fixing frame 2 is in close contact with the tablet press. The other end of the suction cup 8 passes through the other side of the fixing frame 2 and is connected to a vacuum pump (not shown in the figure). The air in the space between the suction cup 8 and the tablet press is extracted by the vacuum pump, so that the suction cup 8 is tightly attached to the tablet press, and the fixing and installation of the feeding cylinder 1 and the tablet press through the fixing frame 2 are completed.

[0039] Furthermore, a vent hole is provided at the other end of the suction cup 8, and a pressure relief button 9 is embedded in the vent hole. When the feeding cylinder 1 needs to be disassembled, by pulling out the pressure relief button 9 in the vent hole, the space between the suction cup 8 and the tablet press is filled with air, and the fixing frame 2 and the tablet press can be easily separated and removed.

[0040] In some embodiments, arc-shaped portions 51 are respectively provided at both ends of the flow guide plate 5, and the arc-shaped portions 51 are matched with the inner wall radian of the feeding cylinder 1. If the upper part of the feeding cylinder 1 is designed as a cylindrical shape, then the two ends of the flow guide plate 5 in contact with the inner wall of the feeding cylinder 1 are designed as arc-shaped portions 51, and the arc-shaped portions 51 are used to fit with the inner wall of the feeding cylinder 1 so that the material does not fall on the connecting platform 3.

[0041] Of course, when the feeding cylinder 1 is designed in a square shape, the two ends of the flow guide plate 5 in contact with the inner wall of the feeding cylinder 1 do not need to be designed as arc-shaped portions 51.

[0042] In summary, after reading the documents of the present utility model, those of ordinary skill in the art can make various other corresponding transformation schemes without creative mental labor according to the technical solutions and technical concepts of the present utility model, and all of them fall within the scope protected by the present utility model.
