Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical intermediate processing, and relates to a pharmaceutical intermediate production and processing discharging device. Background Art

[0002] The processing of pharmaceutical intermediates includes raw material preparation, reaction preparation, separation and purification, drying and packaging. When preparing raw materials, it is often necessary to mix multiple raw materials through a stirring device, and then fill the raw materials separately after mixing for later processing. Therefore, a discharging device is needed to fill the raw materials.

[0003] A filling device for producing pharmaceutical intermediates disclosed in Chinese patent CN220076827U is provided with a turntable, a second discharge pipe and a second connecting rod. The material and specification of each group of second discharge pipes are different, so that during filling, the appropriate second discharge pipe can be selected at any time by rotating the turntable according to the chemical properties of different pharmaceutical intermediates.

[0004] When the filling device is in use, the filling container is placed on the slide, and the second motor is started to drive the two sets of clamps to move horizontally relative to each other, so that the two clamps clamp and fix the filling container. The storage bin is fixedly arranged directly above the slide, and the two sides of the slide are sealed by two support plates. When taking out the filling container, since the container is heavy after filling, it is necessary to move the container horizontally out from between the two support plates before taking the container upward, which is inconvenient to operate. If you are not careful, it is easy to take the container directly diagonally upward, causing the top of the container to collide with the second discharge pipe. In addition, the discharge pipe used for discharging needs to be disassembled frequently for cleaning.

A rubber pad is provided on the inner wall of the placement groove, and the clamping of the discharge pipe 23 is more stable through the rubber pad.

[0049] Working principle:

[0050] When in use, the raw material to be filled is introduced into the storage bin 6 through the feed port 8, and the first motor 7 is started to rotate the stirring rod to stir the raw material.

[0051] During filling, the material barrel 15 is placed on the top of the workbench 17 and between the two clamping plates 3. The top end of the discharge pipe 23 is clamped on the moving plate 9. The second motor 18 is started to drive the second screw rod 13 to rotate clockwise. The second screw rod 13 rotates on the slide plate, causing the slide plate to slide in the first groove 12, driving the workbench 17 to slide on the upper surface of the base 1, and moving the material barrel 15 close to the support frame 5.

[0052] When the workbench 17 moves, it drives the second gear 20 to move on the first rack 2, so that the second gear 20 rotates while moving. The second gear 20 drives the third screw rod 22 to rotate, so that the two sliders 16 on the third screw rod 22 move toward each other, and the sliders 16 pull the corresponding clamping plates 3 through the springs 21, so that the two clamping plates 3 move toward each other.

[0053] The workbench 17 drives the second rack 14 to move together, and when the second rack 14 contacts the first gear 11, the first gear 11 is driven to rotate. The first gear 11 drives the first screw rod 10 to rotate, so that the moving plate 9 slides upward in the two third grooves 25.

[0054] When the barrel 15 moves to the bottom of the discharge port 4, the slider 16 slides to the bottom of the barrel 15, the clamping plate 3 contacts the outer surface of the barrel 15, and the slider 16 continues to move, stretching the corresponding spring 21, so that the two clamping plates 3 clamp the barrel 15. At this time, the discharge port 4 is located in the middle of the top surface of the barrel 15, and the top end of the discharge pipe 23 is sleeved on the discharge port 4.

[0055] The valve on the discharge port 4 is opened to allow the raw materials to pass through the discharge pipe 23 and fall into the barrel 15 for filling.

[0056] After the filling is completed, the second motor 18 is started to drive the second screw rod 13 to rotate counterclockwise. When the workbench 17 slides toward the outside of the support frame 5, the two sliders 16 will move in opposite directions, push the spring 21 to its original state, and then compress the spring 21, and then push the corresponding clamping plate 3 through the spring 21. The two clamping plates 3 move in opposite directions and leave the barrel 15. The moving plate 9 will also move downward, driving the discharge pipe 23 to move downward, so that the discharge pipe 23 leaves the discharge port 4.

[0057] When the workbench 17 slides to the initial position, the filled barrel 15 is removed and replaced with a new barrel 15. At the same time, the discharge port 4 and the discharge pipe 23 can be cleaned, or the discharge pipe 23 of a suitable length can be replaced according to the size of the new barrel 15.

[0058] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
