Description

Technical Field

[0001] The present invention relates to the technical field of powder tablet pressing machines, in particular to a powder tablet pressing machine with an automatic feeding function. Background Art

[0002] In the process of making ceramic tablets, a powder tablet press and tablet die are usually used for extrusion molding. The tablet die consists of four parts: an upper pressing head, a die sleeve, a die base, and a gasket. First, the die base and die sleeve are assembled, and then the gasket is placed into the groove in the die sleeve. Then, powder material is added. The upper pressing head is then inserted into the groove above the die sleeve of the tablet press. Then, the tablet press is placed in the powder tablet press to apply pressure for tableting.

[0003] However, after the powder material is extruded and molded in existing powder tablet presses, the tableting die must be manually rotated 180 degrees to remove the die base and gasket before the tablet material can be removed. Sometimes the gasket cannot be directly removed manually, causing the formed tablet to become stuck inside the die and unable to be removed. Therefore, the inverted tableting die (after removing the die base) must be placed in the powder tablet press and re-pressed to remove the gasket and tablet material. The entire process is cumbersome and not automated, making it difficult to use. Summary of the Invention

[0004] The purpose of the present invention is to solve the disadvantage that the tablet pressing die cannot be automatically turned upside down 180 degrees to press and remove the tablets, and a powder tablet pressing machine with automatic unloading function is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0024] The technical solution of the present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1-4 As shown, the present invention proposes a powder tablet press with automatic unloading function, including a tablet press body 1 and a mold, wherein the mold includes a die sleeve 10, an upper pressing head 11, a die base 12 and a gasket. The movable gasket is inside the die sleeve and can be removed. A placement table 2 is installed inside the tablet press body 1, a threaded rod 4 is threadedly connected to the upper side of the tablet press body 1, and a turntable 5 is fixedly connected to the upper side of the threaded rod 4. A pressure device 7 is fixedly connected to one side of the tablet press body 1, a pressure gauge 8 is installed on the upper side of the pressure device 7, and a pressure regulating rod 9 is rotatably connected to the outside of the pressure gauge 8;

[0026] A mounting base 13 is fixedly connected to the other side of the tablet press body 1. A height adjustment mechanism 14 is installed on the top surface of the mounting base 13. A position adjustment mechanism 15 is installed above the height adjustment mechanism 14. A steering mechanism 16 is installed on the position adjustment mechanism 15. A clamping mechanism 17 is installed on the steering mechanism 16.

[0027] The outer rotation connection of the tablet press body 1 is provided with a screw part 3, and the upper side of the turntable 5 is fixedly connected with a handle 6. The turntable 5 can be driven by the handle 6 to rotate and adjust the threaded rod 4 to move up and down. The pressure of the placement table 2 and the threaded rod 4 on the die sleeve 10 can be changed by shaking the pressure adjustment rod 9. Usually, the display of the pressure gauge 8 is less than 10MPa.

[0028] The upper side of the tablet pressing mold is movably connected to an upper pressing head 11, and the lower side of the mold sleeve 10 is movably connected to a mold base 12. When extruding the powder material, the mold base 12 and the mold sleeve 10 are first assembled, and then the gasket is placed in the groove of the mold sleeve 10, and then the powder material is added, and then the upper pressing head 11 is inserted into the groove on the upper side of the mold sleeve 10, and then pressure can be applied to press the tablet.

[0029] The position adjustment mechanism 15 includes a rodless cylinder 15-1 installed above the height adjustment mechanism 14, and a movable frame 15-2 is connected to the slider 15-1-1 of the rodless cylinder 15-1, and the steering mechanism 16 is installed at the end of the movable frame 15-2; the height adjustment mechanism 14 can adopt a cylinder with a guide rod.

[0030] The steering mechanism 16 includes a steering motor 16 - 1 installed at the end of the moving frame 15 - 2 . The output end of the steering motor 16 - 1 is connected to a rotating rod 16 - 2 via a coupling. The other end of the rotating rod 16 - 2 is installed with the clamping mechanism 17 .

[0031] like Figure 4 As shown, the clamping mechanism 17 includes a clamping cylinder 17-1 installed at the end of the rotating rod 16-2, and clamping arms 17-2 are installed on the front and rear sides of the clamping cylinder 17-1.

The other end of the connecting rod 17-5-1 is connected to a clamping head 17-5-2. The dimensions between the four clamping heads 17-5-2 on the same horizontal plane match the dimensions of the mold. Specifically, the upper pressing head 11 is smaller than the dimensions of the mold sleeve 10 and the mold base 12. Therefore, the connecting rod 17-5-1 at the top of the clamping assembly 17-5 is longer than the connecting rod 17-5-1 at the bottom.

[0033] After the tablet press has tableted the powder material, if the tablet material cannot be taken out from the inside, the height adjustment mechanism 14 drives the position adjustment mechanism 15 to rise, and the slider 15-1-1 drives the movable frame 15-2 to move to the right, so that the clamping mechanism 17 approaches and clamps the mold. After that, the steering motor 16-1 can be operated to rotate the rotating rod 16-2, thereby driving the mold to flip, and then it can automatically flip 180 degrees for tableting and discharging.
