When filling, the gathering frame is in contact with the die disc, and the powder raw material is transported into the gathering frame. A plurality of vertical scraper parts are arranged on the gathering frame. The scraper parts can scrape off the excess powder raw material on the die disc. However, when the die disc rotates fast, there is a problem that the powder raw material cannot be filled into the die hole in time. Therefore, the tableting speed will be limited by the amount of filler during tableting. Therefore, it is necessary to design a tablet press filling structure. Utility Model Content

[0005] In view of the above technical problems, the purpose of the utility model is to overcome the problem in the prior art that when the amount of filler is large, increasing the tableting speed will affect the filling rate in the die hole.

[0025] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0026] In the present utility model, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0027] like Figure 1-4 As shown, a tablet press filling structure comprises a horizontal material gathering frame, wherein the material gathering frame comprises a square material feeding frame 1 and a strip frame 2 connected to the material feeding frame 1, and the inner wall of the strip frame 2 is provided with at least one material pressing tablet whose two side edges are respectively fixedly attached to the two side walls opposite to the material pressing frame;

[0028] The pressing sheet includes an inclined portion 3 whose lower end is inclined away from the feed frame 1 and an arc portion 4 connected to the lower end of the inclined portion 3. The arc portion 4 is arranged away from the lower end of the inclined portion 3 and away from the feed frame 1. The arc portion 4 is arranged at a distance from the bottom of the strip frame 2 to form a pressing channel.

[0029] The powdered raw material is transported to the feed frame 1, and the bottom side of the feed frame is in sliding contact with the upper surface of the mold disk. When the mold hole on the mold disk moves to the feed frame 1, the powdered raw material in the feed frame 1 will be filled downward into the mold hole; the mold disk will drive the powdered raw material to move toward the feed frame 1 during rotation. When the mold hole moves to the pressing sheet, since the distance between the pressing sheet and the bottom of the strip frame 2 decreases successively in the direction away from the feed frame 1, when the mold disk drives the powdered raw material to move toward the pressing sheet, the inclined pressing sheet can exert a downward force on the powdered raw material, thereby pressing the powdered raw material into the mold hole, so as to increase the filling degree of the powdered raw material in the mold hole, and can increase the rotation speed of the mold disk, thereby improving the tableting efficiency.

[0030] While the inclined portion 3 intercepts the powder raw material, it can also introduce the powder raw material into the arc portion 4. The function of the arc portion 4 is to further compact the powder raw material. Part of the powder raw material is pressed into the mold hole, and other powder raw materials will pass through the pressing channel. The end of the strip frame 2 away from the feed frame 1 can scrape off the excess powder raw material on the mold plate.

[0031] The cross section of the pressing sheet is V-shaped, and the tip of the middle portion of the cross section of the pressing sheet is arranged away from the feed frame 1 .

[0032] The middle tip of the cross section of the pressing sheet corresponds to the die hole. The V-shaped cross section can play a role in gathering materials, so that the powder raw material moves toward the middle of the pressing sheet, and the die hole is driven by the die plate to enter the gathering frame, which is conducive to filling the powder raw material into the die hole.

[0033] The number of the pressing sheets is at least two, and the spacing between the pressing sheets and the bottom of the strip frame 2 decreases in sequence in the direction away from the feed frame 1 .

[0034] The pressing sheets will compact the powdered raw materials while intercepting them. Because part of the powdered raw materials will pass through the pressing channel, the distance between several pressing sheets and the bottom of the strip frame 2 decreases successively in the direction away from the feed frame 1. This can not only control the amount of raw material powder passing through, but also the compaction strength of the raw material powder increases as the distance decreases, which is more conducive to pressing the raw material powder into the mold hole and improving the filling degree of the mold hole.

[0035] The opening angles of the V-shaped cross sections of the plurality of pressing sheets increase in sequence in a direction away from the feeding frame 1 .

[0036] The protrusion of the middle tip of the pressing sheet gradually decreases in the direction away from the feed frame 1, which can not only control the amount of raw material powder passing through, but also the compaction strength of the raw material powder is higher as the spacing decreases, which is more conducive to pressing the raw material powder into the mold hole and improving the filling degree of the mold hole.

[0037] The inner wall of the strip frame 2 is equipped with a scraper unit located on the side of the pressing sheet away from the feeding frame 1;

[0038] The scraper unit includes a rotating plate 5 installed on the side wall of the strip frame 2 through a horizontal rotating shaft on the top side, a scraper 6 detachably installed on the inclined bottom side of the rotating plate 5, and a counterweight 7 installed on the rotating plate 5. The inclined bottom side of the rotating plate 5 is inclined toward the feed frame 1, and the two side edges of the rotating plate 5 are in sliding contact with two opposite side walls of the strip frame respectively.

[0039] Under the action of the counterweight 7, the blade of the scraper 6 is in contact with the mold disc, so as to scrape off excess raw material powder. When the blade of the scraper 6 is gradually worn during use, the counterweight 7 can press the turn plate 5 to rotate downward, so that the blade of the scraper 6 is always in contact with the mold disc.

[0040] The counterweight 7 is connected to the rotating plate 5 via at least one mounting bolt 8 . The rotating plate 5 is provided with at least one threaded seat 9 matching the mounting bolt 8 . The counterweight 7 is provided with a countersunk hole 10 for the mounting bolt 8 to pass through.

[0041] When it is necessary to replace the counterweight 7 with a different weight, the mounting bolts 8 can be loosened and removed to remove the counterweight 7 and replace it with a counterweight 7 of a different weight, thereby controlling the force applied to the scraper 6.

[0042] A clamping strip 11 parallel to the rotating shaft is arranged on the inclined bottom side of the rotating plate 5 , and a clamping sleeve portion 12 matching with the clamping strip 11 is arranged on the scraper 6 .

[0043] When the scraper 6 needs to be replaced, rotate the rotating plate 5 upward so that the scraper 6 rotates upward and moves out of the material gathering frame, pull the scraper 6 horizontally, drive the clamping sleeve 12 to slide on the clamping strip 11, and remove the scraper 6; then slide the clamping sleeve 12 on the new scraper 6 horizontally onto the clamping strip 11.

[0044] When the rotating plate 5 and the scraper 6 are located inside the strip frame 2 , the scraper 6 will not be separated from the rotating plate 5 because the two sides of the rotating plate 5 are in sliding contact with the two side walls of the strip frame 2 .

[0045] The top of the aggregate frame is equipped with a shell which is spaced apart from the top of the press sheet.

[0046] It is not shown in the outer shell diagram that when the strip frame 2 is away from the feed frame 1 and is filled with powder raw materials, the accumulated powder raw materials can move over the top of the pressing sheet to the side of the pressing sheet close to the feed frame 1.

[0047] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present utility model will not further describe various possible combinations.

[0049] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
