Description

Technical Field

[0001] The utility model relates to the technical field of tablet medicines, in particular to a manual tablet press for aquatic feed powder. Background Art

[0002] The water resistance of aquatic pellet feed refers to the resistance of feed to dissolution in water, which usually indicates the dissolution rate of feed pellets in water under specified conditions.

[0003] When designing the ingredients, a water resistance test is required. At this time, the proportionally reduced formula needs to be crushed first, then mixed, and then tempered, and finally pressed into sheets or extruded into granules.

[0004] The equipment needed for tablet pressing is a manual tablet press. Existing tablet presses are mostly punch-type tablet presses, which have complex and heavy structures and require the use of screws or hydraulics to provide pressure. They are extremely inconvenient to use and are mostly used for large-scale commercial purposes in factories. It is not realistic to use them in laboratories.

[0005] In the prior art, there are also inventors who provide a tablet press with a relatively simple structure, such as the structures disclosed in application numbers: 2018200196542 and 2015200806179, both of which include a base, a bracket arranged on the base, and a pressure rod hinged on the bracket, and the top of the upper mold is hinged on the top of the pressure rod. Although this structure is simple, when tableting, since the upper mold and the pressure rod are rotatably connected, during the pressing process, it is necessary to hold the upper mold manually so that the upper mold falls into the lower mold more accurately. It can be imagined that force must be used during the pressing process to achieve the purpose of tableting. However, due to structural defects, during the pressing process, in order to ensure that the upper mold falls accurately into the lower mold, it cannot be pressed down with a large force in the early stage of the pressing. Only after the upper and lower molds are closed can they be compacted with force, wasting the force of the downward punch. Utility Model Content

[0006] The utility model aims to provide a manual tablet press for aquatic feed powder to solve the above problems.

[0007] The technical solution adopted by the utility model is: a manual tablet press for aquatic feed powder, comprising a base plate, a column is vertically arranged on one side of the top of the base plate, and the rear end of the support frame is vertically slidably arranged on the column;

[0008] The punch rod vertically penetrates the front end of the support frame, and the punch head is installed at the lower end of the punch rod through a connecting screw;

[0009] A lower die mounted on the top of the base plate is provided directly below the punch;

[0010] The spring is sleeved on the outer periphery of the punch rod, and the spring is located between the support frame and the top of the punch rod for reset movement;

[0011] The support frame comprises a slide body, the rear end of the slide body has a rear tube portion, the front end has a front tube portion, the column penetrates the center hole of the rear tube portion, the punch penetrates the center hole of the front tube portion, and the connecting portion in the middle connects the rear tube portion and the front tube portion;

[0012] A middle tube portion with a horizontal axis is also provided at the rear end of the front tube portion, a driving wheel is provided in the central hole of the middle tube portion, a toggle member is connected to the driving wheel and drives the driving wheel to rotate, and a toothed portion meshing with the driving wheel is provided on the rear side of the punch rod;

[0013] An opening is arranged at the rear of the rear tube portion, and a locking plate is arranged on both sides of the opening respectively. The locking member penetrates through the two locking plates to lock the slide body at a suitable position of the column.

[0014] Furthermore, a detachable limiting ring is provided on the top of the punch rod, the limiting ring blocks the top of the spring, and the limiting ring is connected to the top of the punch rod via a connecting screw.

[0015] Beneficial effects:

[0016] During the pressing process, the tablet press does not need to be supported by hands, but can rely on its own structure to operate the upper die with a large punch to perform punching, thereby obtaining good products and having the advantages of simple structure and convenient maintenance.
