[0001] This utility model belongs to the technical field of capsule filling machines, and in particular relates to a blowing and discharging device for capsule filling machines. Background Technology
[0002] Capsule filling machines are key pieces of equipment affecting production progress. After the capsules are filled with medicine powder, they are compacted and transported to the discharge port. There, they are ejected into the receiving container by a mechanical scraper connected to a cylinder. The mechanical scraper has a large impact force, which can cause capsules to break during operation. Moreover, the cylinder strikes twice per second, and the high operating speed causes severe wear on the cylinder. This often leads to malfunctions and machine shutdowns, affecting the normal production process. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a blowing and discharging device for a capsule filling machine.

[0009] Preferably, the upper end of the receiving plate is hinged to the discharge pipe by a torsion spring, and the torsion spring causes the receiving plate to flip upward.
[0010] Preferably, a limiting block is provided between the receiving plate and the discharge pipe. The limiting block is located on the upper side of the upper end of the receiving plate. When the receiving plate touches the limiting block, the receiving plate is in an inclined state.

[0019] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0021] Example 1
[0022] As shown in Figures 1 and 2, a blowing and discharging device for a capsule filling machine is characterized by comprising a discharge pipe 1 and an air knife 2. The discharge pipe 1 comprises an integrally formed receiving section 101 and a discharge section 102. The receiving section 101 is L-shaped, and the discharge section 102 is I-shaped. The upper end of the discharge section 102 is connected to the horizontal end of the receiving section 101. The air knife 2 is disposed on the side away from the discharge section 102, outside the lower end of the vertical section of the receiving section 101. The air discharge direction of the air knife 2 is towards the discharge section 102.
[0023] A receiving plate 3 is provided in the lower part of the vertical section of the receiving section 101. The upper end of the receiving plate 3 is connected to the side of the vertical section of the receiving section 101 near the discharge section 102, and the lower end of the receiving plate 3 is inclined downward.
[0024] When the capsule falls into the vertical section of the receiving section 101, it will first land on the receiving plate 3. The inclined receiving plate 3 can guide the capsule to move towards the discharge section 102, playing a preliminary guiding role.
[0025] A gap is left between the lower end of the receiving plate 3 and the side of the vertical section of the receiving section 101 away from the discharge section 102, and a gap is left between the lower end of the receiving plate 3 and the bottom surface of the horizontal section of the receiving section 101.
[0026] The existence of these gaps allows airflow to pass through better, enhancing the purging effect of the air knife 2; on the other hand, it prevents the capsule from getting stuck between the receiving plate 3 and the inner wall of the receiving section 101, ensuring smooth discharge; and it also effectively improves the pushing effect of the air knife 2, achieving a good pushing effect with a small pushing force, reducing the capsule breakage rate.
[0027] The upper end of the receiving plate 3 is hinged to the discharge pipe 1 by a torsion spring. The torsion spring drives the receiving plate 3 to flip upward. A limit block 4 is provided between the receiving plate 3 and the discharge pipe 1. The limit block 4 is located on the upper side of the upper end of the receiving plate 3. When the receiving plate 3 touches the limit block 4, the receiving plate 3 is in an inclined state.
[0028] When a capsule lands on the receiving plate 3, the capsule's gravity causes the receiving plate 3 to overcome the torsion spring's force and rotate downwards at a certain angle, allowing the capsule to slide smoothly. After the capsule leaves the receiving plate 3, the torsion spring causes the receiving plate 3 to flip upwards back to its initial position, preparing for the next capsule to land. The limiting block 4 restricts the upward flipping angle of the receiving plate 3, ensuring that the receiving plate 3 is always at a suitable tilt angle for better receiving and guiding of the capsule.
[0029] A buffer pad 5 is provided at the connection between the discharge section 102 and the receiving section 101. The buffer pad 5 is located on the upper end of the discharge section 102 away from the receiving section 101. The buffer pad 5 is made of elastic material, and the side of the buffer pad 5 facing the receiving section 101 is curved.
[0030] When the capsule is blown from the receiving section 101 to the discharging section 102, it may collide with the connection point of the discharging section 102. The buffer pad 5 can act as a buffer to reduce the damage to the capsule caused by the collision. The elastic material can better absorb the energy generated when the capsule collides, and the curved design can make the capsule transition more smoothly from the receiving section 101 to the discharging section 102, further reducing the possibility of capsule damage.
[0031] The upper part of the discharge section 102 is equipped with multiple air outlets 6. By changing the air output of all these air outlets 6, the airflow in the discharge section 102 can be made more uniform, which helps the capsule move smoothly in the discharge section 102, and at the same time prevents the pressure in the discharge section 102 from being too high, thus ensuring the stability of the discharge process.
[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
