s2: the clamping mechanism clamps and limits the template provided with the capsule bottom shell;

s3: the medicine spraying mechanism sprays medicine on the capsule bottom shell provided with the capsule bottom shell.

The working principle is as follows: this theory of operation is embodiment one theory of operation, at first open two sets of conveyer belts, make the template that is equipped with the capsule drain pan constantly spread from being close to the conveyer belt of getting flitch 10 one side, get into workstation 1, open the motor in two motor boxes 3 afterwards, the output shaft of two motors turns to conversely, two motors drive screw rod 5 simultaneously and rotate, two screw rod 5 are spacing through spacing 7, and be threaded connection's structure between screw rod 5 and the delivery sheet 6, reach and drive delivery sheet 6 and carry out reciprocating motion on the workstation upper surface.

The feeding plate 6 is connected with the material taking plate 10 through a fixed block 8 and a connecting plate 9 and drives the material taking plate 10 to reciprocate and synchronously move, the two sides of the material taking plate 10 close to the limiting plate 11 are in limiting sliding connection in the parallelogram groove 12 through a first sliding shaft 13 which is fixedly connected, the effect of limiting the moving track of the material taking plate 10 is achieved, and the material taking plate 10 can only move in the parallelogram groove 12,

a rectangular block 14 which is connected in the groove in a limiting and sliding way through a groove structure arranged in the diagonal angle of the parallelogram groove 12, and the first spring 39 fixedly connected between the lower surface of the rectangular block 14 and the inner lower surface of the groove structure, when the material taking plate 10 takes off the material backwards, when the first sliding shaft 13 passes through the rectangular block 14 under the pushing of the material taking plate 10, the rectangular block 14 is pressed into the groove structure, at this time, the first spring 39 is pressed, when the first sliding shaft 13 completely passes through the rectangular block 14, the first spring 39 loses pressure to reset and pushes the rectangular block 14 out of the groove, at this time, the material removing plate 10 finishes the material raking and starts to rake again, under the block of the rectangular block 14, the first sliding shaft 13 can only move upwards along the parallelogram track under the thrust of the material taking plate 10, and then the material removing plate comes to the obliquely upper part of the new template again, and the material taking plate 10 is used for continuously raking the template filled with the capsules towards the direction of the feeding plate 6.

In the feeding mechanism, after the material taking plate 10 completes one material taking action in the parallelogram groove 12, the template with the capsule bottom shell is taken to a position close to the feeding plate 6 by the material taking plate 10, and when the material taking plate 10 takes the material again, the material taking plate 10 is connected with the connecting plate 9 through the pin shaft of the fixing block 8, and the feeding plate 6 is driven to move towards the direction of the template with the capsule taken to the position close to the feeding plate 6 by the material taking plate 10.

When 6 removal templates of delivery sheet are over, because the height of template blocks, 35 bottom atress of cardboard that rotate this moment to connect in 6 bottom draw-in grooves of delivery sheet turn over a rotation, after 35 rotates certain angle of cardboard, cardboard 35 begins the laminating to remove at the template upper surface under 6 continuous drives of delivery sheet, be of value to reach when not influencing 6 removals of delivery sheet, drive cardboard 35 and carry out the effect that removes

When the feeding plate 6 completely moves to the position right above one side of the template close to the material taking plate 10, the lower surface of the clamping plate 35 leaves the upper surface of the template and naturally droops under the action of gravity, at the moment, the material taking plate 10 starts to drive a new template to move towards the feeding plate 6, the feeding plate 6 also starts to synchronously move towards the direction of the medicine spraying box 4 through the pin connection of the fixed block 8 and the connecting plate 9, and further drives the clamping plate 35 to move, because the clamping strip 36 is fixedly connected with one side of the clamping plate 35 opposite to the medicine spraying box 4, when the clamping plate 35 moves towards the medicine spraying box 4, the clamping plate 35 is limited at one side of the clamping plate 35 opposite to the medicine spraying box 4, so that the clamping plate 35 cannot be stressed to continuously rotate, can only keep a downward vertical state under the driving of the feeding plate 6, and is attached to the outer side of the template in the moving process and drives the template to move towards the direction of the medicine spraying box 4, and the feeding mechanism continuously performs arc-shaped material taking on the template provided with a capsule bottom shell, the template with the capsule bottom shell is synchronously and stably moved again and sent to the spraying mechanism.

In the feeding mechanism, when the feeding plate 6 drives the template provided with the capsule bottom shell to move towards the direction of the medicine spraying box 4, two parallel plates 15 which are symmetrically and fixedly connected with one side of the feeding plate 6 close to the motor box 3 synchronously move towards the direction of the motor box 3, so that the motion effect of synchronously driving the clamping mechanism through the linkage of the feeding mechanism is achieved, at the moment, a limiting sliding groove 23 arranged at the opposite side of the parallel plates 15 slides outside a second sliding shaft 16 when the flat plates 15 move towards the direction of the motor box 3, after the parallel plates 15 drive the limiting sliding groove 23 to slide for a certain distance, the inner wall of one end of the limiting sliding groove 23 close to the feeding plate 6 begins to be attached to the second sliding shaft 16, and when the parallel rods 15 continue to move towards the direction of the motor box 3, the action that the limiting sliding groove 23 extrudes a first push rod 17 through the fixed connection between the second sliding shaft 16 and the first push rod is achieved, according to the fact that the first push rods 17 are connected with the second push rods 18 through pin shafts, when the two first push rods 17 move, the two second push rods 18 are driven to move relatively under the limiting effect of the limiting sleeves 19, and clamping is achieved.

Meanwhile, the template of being equipped with the capsule drain pan is brought into by feed table 6 gradually and spouts under medicine box 4, after feed table 6 moves, the template is just in time under spouting medicine box 4 this moment, at this moment, two second push rods 18 drive fixed connection's clamp plate 22 just in time carry out the pressfitting spacing to getting into the template outside of being equipped with the capsule drain pan under spouting medicine box 4, reached that feed mechanism is continuously getting the material and the pay-off, drive fixture when feed mechanism will be equipped with the template propelling movement of capsule drain pan and spout medicine box 4 under, carry out the effect of centre gripping to the template outside, liquid medicine when having avoided spouting in the inaccurate drain pan of dropping capsule in the template of liquid medicine.

In the motion process of the clamping mechanism, when the two pressing plates 22 drive the ejector rods 20 connected by the two pin shafts to move relatively, the relative distance between the pressing plates 22 is gradually reduced, so that the ejector rods 20 gradually rise and drive the top plate 21 to rise, and then the top plate 21 drives the push plate 24 to gradually rise in the T-shaped groove 25, and the effect of extruding the air in the T-shaped groove 25 is achieved.

When air in the T-shaped groove 25 enters the square bins 26 through two ends of the T-shaped groove 25 under the extrusion of the push plate 24, the air pressure in the two square bins 26 is increased to drive the piston plate 28 to move downwards against the pulling force of the second spring 27, the piston plate 28 starts to be attached to the upper surface of the circular table 30 after moving downwards for a certain distance, the lower part of the circular table 30 is extruded out of the through hole formed in the lower part of the medicine spraying box 4 in the continuous downward movement of the piston plate 28, a gap with a certain size is formed between the circular table 30 and the through hole at the moment, so that liquid medicine can flow out from the gap between the through hole and the circular table 30 and enter the spray head 32, and finally the liquid medicine is dripped into the corresponding capsule bottom shell in the template through the spray head 32, when the feeding mechanism is reset to drive the clamping mechanism to reset, the relative distance between the press plates 22 is increased, so that the two ejector rods 20 drive the top plate 21 and the push plate 24 to start to vertically move downwards, and then make the air pressure in T type groove 25 reduce to second spring 27 drives piston plate 28 and begins to reset upward movement, and then makes round platform 30 break away from briquetting 29, and briquetting 29 drives round platform 30 under the elasticity of third spring and resets, and check valve 33 opens simultaneously herein, and new liquid medicine carries out between piston plate 28 lower surface and square storehouse 26 through transfer line 34, reaches the effect of automatic re-setting and mending after the medicine is over.

In the continuous motion of the feeding mechanism, when the feeding plate 6 performs reciprocating motion, the template of the capsule bottom shell filled with the non-dropwise-added liquid medicine is continuously transported backwards, the template after the medicine spraying is finished can be extruded out of the upper surface of the workbench 1 by the template newly entering the position right below the medicine spraying box 4 and enters the conveying belt at the rear side of the workbench 1, the conveying belt at the rear side of the workbench finally conveys the capsule template after the liquid medicine is dropwise added to the final process for mold closing, the top shell and the bottom shell of the capsule are fixed, and the intelligent dropwise adding preparation of the radioactive therapy capsule is finished.
