Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, a pressing and taking-out mechanism for powder tablets comprises a lower die 1, a counterweight compression ring 2 is movably sleeved in an inner cavity at the top of the lower die 1, a communicating groove 3 communicated with a middle cavity of the lower die 1 is arranged in the inner cavity at the top of the lower die, a conveying pipeline 4 is arranged on one side of a cavity at the top of the lower die 1, an upper die 5 is movably sleeved in the middle cavity of the lower die 1, an extrusion sleeve 6 is fixedly arranged at the top end of the upper die 5, a movable connecting rod 7 communicated with the top of the extrusion sleeve 6 is movably sleeved in the upper die 5, a sliding block 8 is movably sleeved in the middle of the inner cavity of the extrusion sleeve 6, and the inside of sliding block 8 and the top of activity connecting rod 7 surface between fixed cup jointing, the middle part of activity connecting rod 7 surface just is located the activity and is cup jointed absorption spring 9 between the top of sliding block 8 and the bottom of 6 inner chambers of extrusion sleeve.

Wherein, to the setting of last mould 5, extrusion sleeve 6 and movable connecting rod 7, when the in-process that extrusion sleeve 6 moved up, under the elastic force effect of adsorption spring 9 for go up mould 5 and movable connecting rod 7 on it can stagger each other, and then form the negative pressure among the inner chamber of last mould 5, and absorb out in the inner chamber at lower mould 1 middle part the tablet that will suppress, and no longer need extra power extrusion device to take out in the cavity at lower mould 1 middle part with the tablet that will suppress, simple structure and convenient to use.

Wherein, to lower mould 1 and the setting of structure on it to carry the powder tablet raw materials in the cavity at lower mould 1 middle part, thereby after the tablet pressing is accomplished in getting the tablet, can be to wherein carrying the powder tablet raw materials, and then greatly reduced this tablet pressfitting take out mechanism's preforming efficiency.

In this technical scheme, the bottom of 1 top cavity of bed die is equipped with the hemisphere type structure, and the bottom of counter weight clamping ring 2 establishes to rather than matched with hemisphere type structure.

The communicating groove 3 and the internal structure thereof on the lower die 1 are arranged to automatically squeeze and convey the powder tablet raw material in the top cavity of the lower die 1 into the cavity in the middle of the lower die 1 through the communicating groove 3 under the influence of gravity, and the powder tablet raw material is pressed into a sheet-shaped structure in the downward moving process of the upper die 5 and the movable connecting rod 7.

In this technical scheme, form the arc curved surface structure of a completion between the arc structure of activity connecting rod 7 bottom and the bottom arc structure of sliding block 8 when adsorbing the shortest length of spring 9 compression.

Wherein, to the setting of adsorption spring 9 and movable connecting rod 7 to when moving down to the below suppression tablet at movable connecting rod 7, can form comparatively stable and reliable extrusion face by the powder tablet raw materials, and then make the good tablet quality of suppression higher.

In the technical scheme, when the sliding block 8 moves to the position contacted with the top of the inner cavity of the extrusion sleeve 6, the negative pressure value formed in the inner cavity of the upper die 5 by the movable connecting rod 7 is greater than the gravity of the pressed tablet.

The maximum negative pressure value in the inner cavity of the upper die 5 is set, so that the stability of the movable connecting rod 7 in the upward movement process of adsorbing and pressing the tablets is effectively improved, the tablets are not easy to loosen and fall off in the adsorbing and taking-out process, and the stability and reliability of the pressing and taking-out mechanism in the using process are further improved.

The use method and the working principle of the embodiment are as follows:

firstly, the top end of a movable connecting rod 7 is connected with an up-and-down moving power conveying mechanism, and a conveying pipeline 4 is communicated with a pipeline for conveying powder tablet raw materials by gas, so that the powder tablet raw materials can be continuously conveyed into a cavity at the top of a lower die 1 and always have a tendency of being conveyed to a cavity in the middle of the lower die 1 through a communicating groove 3 under the action of the gravity of a counterweight compression ring 2;

as shown in fig. 2: when the movable connecting rod 7 on the pressing and taking-out mechanism moves downwards, the adsorption spring 9 is continuously compressed under the action of the sliding block 8 in the inner cavity of the extrusion sleeve 6, so that the sliding block 8 and the upper die 5 at the bottom of the sliding block are driven to gradually move downwards to extrude the powder tablet raw materials in the middle cavity of the lower die 1, and meanwhile, the adsorption spring 9 in the inner cavity of the extrusion sleeve 6 is continuously compressed along with the continuous downward movement of the movable connecting rod 7, so that a finished arc-shaped curved surface structure is formed between the bottom end of the movable connecting rod 7 and the bottom end of the upper die 5, and the powder tablet raw materials in the middle cavity of the lower die 1 are pressed into a specific sheet structure;

as shown in fig. 3: when the movable connecting rod 7 on the pressing and taking-out mechanism moves upwards, the sliding block 8 and the upper die 5 on the sliding block keep a downward pressure trend under the action of the elastic force of the adsorption spring 9 in the inner cavity of the extrusion sleeve 6, and the bottom end of the upper die 5 and the bottom end of the movable connecting rod 7 are staggered with the upward movement of the movable connecting rod 7, so that negative pressure is formed in the inner cavity of the upper die 5, the pressed tablets are adsorbed at the bottom of the upper die 5, and when the bottom end of the sliding block 8 moves upwards to be in contact with the top of the inner cavity of the extrusion sleeve 6, the extrusion sleeve 6 and the upper die 5 on the extrusion sleeve are driven to move upwards synchronously, and the tablets adsorbed at the bottom end of the upper die 5 are taken out from the cavity in the middle of the lower die 1;

meanwhile, after the upper die 5 moves upwards for a certain height, the communicating groove 3 on the lower die 1 is communicated, and then the powder tablet raw material in the top cavity of the lower die 1 is extruded and conveyed to the cavity in the middle of the lower die 1 through the communicating groove 3 under the action of gravity of the counterweight pressing ring 2, and when the movable connecting rod 7 moves downwards again, along with the reduction of negative pressure in the inner cavity of the upper die 5, the tablet adsorbed at the bottom end of the upper die 5 automatically falls off, and then the steps are repeated to press the powder tablet raw material in the middle cavity of the lower die 1.
