Technical Field

[0001] This utility model relates to the field of lurasidone tablet granulation technology, and in particular to a device for preventing lurasidone tablets from spinning inside a cone hopper. Background Technology

[0002] Currently, during the production of lurasidone tablets, a counting machine drops pre-counted tablets through a dropping gate into a dropping hood. Because the inner wall of the dropping hood is smooth and the surface of the tablets is smooth, the tablets will continuously rotate along the smooth inner wall of the dropping hood during free fall, causing the tablets to fail to fall into the plastic bottle within the specified time, resulting in missing or extra tablets in the plastic bottle. Utility Model Content

[0003] The purpose of this invention is to provide a device that prevents lurasidone tablets from spinning inside the cone, avoids the tablets from sliding on the inner wall of the dropper, and allows the tablets to fall into the plastic bottle within a specified time.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A device for preventing lurasidone tablets from spinning inside a cone-shaped container includes a dropper cover, an inner insert plate inserted inside the dropper cover, the inner insert plate having a cross-shaped cross-section, the dropper cover being conical in shape, and an inclined side with the same cone angle as the conical dropper cover being provided on the side of the inner insert plate.

[0006] By adopting the above technical solution, the tablets can be effectively prevented from sliding on the inner wall of the dropper cover, ensuring that the tablets fall into the medicine bottle within the specified time.

[0007] Furthermore, a heating cover is installed on the outer cover of the falling grain shield. The heating cover is in the shape of a cone, and the cone angle is adapted to the cone angle of the falling grain shield.

[0008] By adopting the above technical solution, a heating cover can be used to protect the internal heating structure.

[0009] Furthermore, a heating resistance wire is wound around the outside of the falling particle shield, and the heating resistance wire is located inside the heating shield.

[0010] By adopting the above technical solution, a heating resistance wire can be used to heat the particle fall protection cover.

[0011] Furthermore, two sealing seats are provided on the side surface of the heating cover, and the two ends of the heating resistance wire pass through the interior of the two sealing seats respectively.

[0012] By adopting the above technical solution, the positional stability of the heating resistance wire can be improved.

[0013] Furthermore, a mounting position is provided on the side surface of the heating cover, and a mounting hole is provided on the outer surface of the mounting position. A temperature sensor is fixedly installed inside the mounting hole, and the detection end of the temperature sensor is placed inside the heating cover.

[0014] By adopting the above technical solution, a stable sensor can be used to monitor the internal temperature of the heating shroud in real time, providing data reference for automatic control.

[0015] Furthermore, a temperature control module is provided on the outside of the heating cover, and the temperature sensor and the heating resistance wire are both electrically connected to the temperature control module.

[0016] By adopting the above technical solution, automatic control operation can be achieved using a temperature control module.

[0017] In summary, the beneficial technical effects of this utility model are as follows:

[0018] 1. In use, the cross-shaped inner insert plate is first inserted into the inside of the dropper cover, and then the dropper cover is installed at the discharge port of the dropper gate. When dropper filling is required, the tablets fall into the conical dropper cover. Under the obstruction of the cross-shaped inner insert plate, the smooth tablets will not rotate against the inner wall of the dropper cover, thereby reducing the time the tablets remain in the dropper cover and avoiding the situation where the tablets fail to fall into the plastic bottle within the specified time, resulting in missing or extra tablets in the plastic bottle.

[0019] 2. This utility model can be used in humid environments by using a heating resistance wire to heat the pellet-feeding cover, thereby increasing the internal temperature of the cover and improving its dryness. This ensures that the tablets can smoothly slide off the inner wall of the cover without sticking. During the heating process, a temperature sensor monitors the internal temperature of the heating cover in real time and transmits the temperature data to the temperature control module. When the set value is reached, the temperature control module stops the heating resistance wire. When the internal temperature of the heating cover drops below the set value, the temperature control module activates the heating resistance wire, enabling precise automatic adjustment. Both functionality and practicality are effectively improved. Attached Figure Description

[0022] The method of this utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figure 1 A device for preventing lurasidone tablets from spinning inside a conical hopper includes a dropper cover 1. An inner insert plate 2 is inserted inside the dropper cover 1. The inner insert plate 2 has a cross-shaped cross section. The dropper cover 1 is conical. The inner insert plate 2 has an inclined side with the same cone angle as the conical dropper cover 1. In use, the cross-shaped inner insert plate 2 is first inserted inside the dropper cover 1, and then the dropper cover 1 is installed at the discharge port of the dropper gate. When dropper filling is required, the tablets fall into the conical dropper cover 1. Blocked by the cross-shaped inner insert plate 2, the smooth-surfaced tablets do not rotate against the inner wall of the dropper cover 1, thus reducing the time the tablets remain inside the dropper cover 1. This prevents tablets from failing to fall into the plastic bottle within the specified time, thus avoiding situations where there are missing or extra tablets in the plastic bottle.

[0024] Reference Figure 1 A heating cover 3 is installed on the outer side of the grain-falling cover 1. The heating cover 3 is conical, and the cone angle matches the cone angle of the grain-falling cover 1. A heating resistance wire 4 is wound around the outside of the grain-falling cover 1 and is located inside the heating cover 3. Two sealing seats 8 are provided on the side surface of the heating cover 3, and the two ends of the heating resistance wire 4 pass through the interior of the two sealing seats 8 respectively. A mounting position 7 is provided on the side surface of the heating cover 3, and a mounting hole is provided on the outer surface of the mounting position 7. A temperature sensor 5 (PT100) is fixedly installed inside the mounting hole. The detection end of the temperature sensor 5 is located inside the heating cover 3. A temperature control module 6 is provided on the outside of the heating cover 3. The temperature sensor 5 and the heating resistance wire 4 are both connected to the temperature control module 6. Module 6 is electrically connected, and when used in a humid environment, the heating resistance wire 4 is used to heat the pellet cover 1, thereby increasing the internal temperature of the pellet cover 1 and improving its dryness. This ensures that the tablets can slide smoothly off the inner wall of the pellet cover 1 without sticking. During the heating process, the temperature sensor 5 monitors the internal temperature of the heating cover 3 in real time and transmits the temperature data to the internal temperature control module 6. When the set value is reached, the temperature control module 6 stops the operation of the heating resistance wire 4. When the internal temperature of the heating cover 3 is lower than the set value, the temperature control module 6 activates the heating resistance wire 4, enabling precise automatic adjustment. Both functionality and practicality are effectively improved.

[0025] Working principle: In use, first insert the cross-shaped inner plate 2 inside the pellet discharge shroud 1, then install the pellet discharge shroud 1 at the discharge port of the pellet discharge gate. When pellet filling is required, the tablets fall into the conical pellet discharge shroud 1. Blocked by the cross-shaped inner plate 2, the smooth-surfaced tablets do not rotate against the inner wall of the pellet discharge shroud 1, thus reducing the time the tablets remain inside the shroud 1. This prevents tablets from failing to fall into the plastic bottle within the specified time, resulting in missing or extra tablets in the plastic bottle. Furthermore, during use, when the external environment is humid, heating is used... The resistance wire 4 is used to heat the pellet-feeding cover 1, thereby increasing the internal temperature of the pellet-feeding cover 1 and improving its dryness. This ensures that the tablets can slide smoothly off the inner wall of the pellet-feeding cover 1 without sticking. During the heating process, the temperature sensor 5 monitors the internal temperature of the heating cover 3 in real time and transmits the temperature data to the temperature control module 6. When the set value is reached, the temperature control module 6 stops the operation of the heating resistance wire 4. When the internal temperature of the heating cover 3 is lower than the set value, the temperature control module 6 restarts the heating resistance wire 4, enabling precise automatic adjustment.

Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
