Description

Technical Field

[0001] The utility model belongs to the technical field of medicine dispensing machines, and in particular relates to a dust collector and a medicine dispensing machine. Background Art

[0002] Chinese medicine formula granules are dry particles. Usually, when dispensing medicine, the dry particles fall into the medicine bag or medicine box after filling the volume cavity through the rotation of the medicine dispensing head. During the transportation and dispensing process, some particles will be pulverized during the collision and grinding of the medicine dispensing head, which will cause the pulverized particles to float on the medicine dispensing port and the sealing part when dispensing medicine. The medicine powder will fall and accumulate in the precision parts and narrow gaps. If it is not handled for a long time, the medicine powder will absorb moisture and cover the inside of the machine, which is difficult to clean and affects the use of the equipment.

[0043] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.

[0044] The dust collector in this embodiment is applied to a medicine dispensing machine. In the medicine dispensing machine, when the Chinese medicine formula particles collide with each other and / or fall into bags, medicine dust will be generated. In addition to affecting the use of components, the medicine dust may also cause incomplete sealing and air leakage.

[0045] like Figure 1 to Figure 3 As shown, a dust collector comprises a device body 1, a valve mechanism and a fan; the device body 1 is provided with at least one dust removal channel 1 2 and at least two dust removal channels 2 3, and the dust removal channels 2 3 and the dust removal channels 1 2 are connected in parallel; the valve mechanism is arranged in the dust removal channels 2 3, and the valve mechanism has a free part 4 and a power part 5, and the free part 4 is driven by the power part 5 to make a part of the dust removal channels 2 3 conductive and another part of the dust removal channels 2 3 closed; the fan is used for supplying or exhausting air, and the fan connects the dust removal channels 1 2 and the dust removal channels 2 3.

[0046] In some technical solutions, the fan is a blower, which can blow the medicine dust generated in the medicine dispenser out of the medicine dispenser. It is known that although such a setting can ensure the cleanliness of the medicine dispensing environment inside the medicine dispenser, the medicine dust blown out of the medicine dispenser will pollute the environment outside the medicine dispenser. Therefore, it is necessary to additionally set up other mechanisms for further dust collection, or manual cleaning. Therefore, such technical solutions have the defects of high cost, complex structure, and high labor intensity. Therefore, as a preferred implementation method, the fan is an exhaust fan, which uses the fan to generate negative pressure suction to absorb and clean the medicine dust generated in the medicine dispenser, thereby ensuring the cleanliness of the environment inside and outside the medicine dispenser.

[0047] In this embodiment, the medicine dispensing machine includes the above-mentioned dust collector, and also includes a medicine dispensing turntable and a sealing machine; one of the dust removal channels 1 2 is connected to the outside of the medicine dispensing turntable, and one of the dust removal channels 2 3 is connected to the inside of the medicine dispensing turntable; one of the dust removal channels 1 2 is connected to the sealing machine; and one of the dust removal channels 2 3 is connected to a hose. That is to say, in this embodiment, the dust collector provides four negative pressure dust suctions for the medicine dispensing machine, wherein the first route uses a small diameter pipe to be connected to the dust suction port at the sealing machine, which is used to seal the medicine bag, discharge the air from the medicine bag, and absorb a small amount of medicine powder at the same time; the second route also uses a small diameter pipe, which is connected to the outside of the medicine dispensing turntable, and is used to absorb the dust that falls from the outer edge of the medicine dispensing turntable. Since the medicine dispensing turntable rotates continuously during the medicine dispensing process, the pipe can be fixed at a certain position for continuous dust suction, that is, during the rotation of the medicine dispensing turntable, the medicine dispensing turntable rotates relative to the pipe; the third route uses a larger diameter pipe to be connected to the inner side of the medicine dispensing turntable, and removes dust with greater suction force, which is used to absorb the main dust generated when dispensing medicine; the fourth route uses a hose, and a dust suction head is provided at the end thereof, which is used by staff to clean the dust and residual dust in narrow spaces that are difficult to clean. In this embodiment, due to the limitation of the equipment space, the power of the dust collector cannot be consistent with the ideal power. Therefore, in order to achieve the ideal dust collection effect, the third and fourth paths require the dust collector to operate with a larger suction force, and in actual use, the third and fourth paths do not need to provide negative pressure suction at the same time. Therefore, during use, in the third and fourth paths, one of them can be turned on and the other can be closed, so that the flow rate of the negative pressure gas in the guide path is greater to improve the suction efficiency of this path.

[0048] In some technical solutions, the dust removal channel 2 can be provided with a solenoid valve to close the dust removal channel 2 during manual dust removal, thereby providing a higher dust removal efficiency for the conductive dust removal channel 23 during manual dust removal. However, if a solenoid valve is provided, the dust removal function will cause drug dust to adhere to the solenoid valve, which will affect the use effect of the solenoid valve in the later stage. In other words, long-term use cannot make the dust removal channel 2 tightly closed. At this time, the dust removal channel 2 also has negative pressure suction, which will attract drug dust to block the dust removal channel 2 or even squeeze it into blocks. Since the diameter of the dust removal channel 2 is still relatively small, when the medicine dispenser is unloading and the solenoid valve is opened, the drug dust that is blocked into blocks will also affect the directional dust suction effect, which is not conducive to the dust removal of the medicine dispenser. Therefore, the dust removal channel 2 in this embodiment is always open to keep the dust removal channel 2 conductive at all times.

[0049] like Figure 3 and Figure 5 As shown, in this embodiment, the free member 4 is linearly slidably connected to the device body 1, or as shown in FIG. Figure 4As shown, the free member 4 is rotatably connected to the device body 1. In this embodiment, in order to simplify the structure, the at least two dust removal channels 23 are arranged side by side, and the free member 4 of the valve mechanism moves along a straight line to open a part of the dust removal channels 23 and close another part of the dust removal channels 23. Further, the valve mechanism includes a sliding member configured as a free member 4, and the sliding member is provided with at least one ventilation hole 6, and the number of the ventilation holes 6 is less than the number of the dust removal channels 23; the power member 5 is used to drive the sliding member to move along a straight line. The sliding member is a sheet structure or a block structure, and the size of the ventilation hole 6 opened therein matches the pipe diameter size of the dust removal channel 23. In this embodiment, there are two dust removal channels 23, so when there is one ventilation hole 6, the dust removal channel 23 can be opened and closed one by one. Specifically, the two dust removal channels 23 are respectively the first channel and the second channel. When the first channel corresponds to the ventilation hole 6, the second channel is blocked by the sliding member. After the driving power member 5 is actuated, the second channel is blocked by the sliding member, and the first channel corresponds to the ventilation hole 6. This embodiment drives the sliding member to move by linear motion, which satisfies the structural size requirement and is conducive to miniaturization. In this embodiment, a guide member, such as a slide rail and slider member, may be provided between the sliding member and the device body 1, so as to better enable the sliding member to move back and forth on a preset reciprocating path.

[0050] In this embodiment, the power member 5 is configured as a screw mechanism or a telescopic rod mechanism or a gear rack mechanism or a multi-link mechanism. When the power member 5 is configured as a screw mechanism, the free end of the screw of the screw mechanism is rotatably connected to the sliding member, so that when the screw rotates, the rotational motion of the screw is quickly and efficiently converted into the linear motion of the sliding member; when the power member 5 is configured as a telescopic rod mechanism, air pressure or hydraulic pressure is often used to push the sliding member to move linearly; when the power member 5 is configured as a telescopic rod mechanism, one of the rods is connected to the sliding member, and the swing is converted into the linear motion of the sliding member through the hinge relationship of each rod. In this technical solution, a cam is also often used.

[0051] In this embodiment, a zero position switch is further included to detect the displacement distance or displacement angle of the free member 4, and the zero position switch is in communication with the power member 5. The zero position switch includes a sensing plate 7 and a sensor 8, and the sensor 8 can be an ultrasonic sensor, an infrared sensor, etc. When the sensing plate 7 is located in the sensing area of ​​the sensor 8, the detection signal can be fed back to the power member 5 to stop the power member 5 from moving, thereby preventing the sliding plate from moving excessively.

[0052] In order to efficiently remove dust during the medicine dispensing process, the present embodiment focuses on arranging dust removal channel 1 2 and / or dust removal channel 2 3 at the position where medicine dust is likely to appear during the medicine dispensing process. To this end, one dust removal channel 1 2 is connected to the sealing machine, one dust removal channel 1 2 is connected to the outside of the medicine dispensing turntable, one dust removal channel 2 3 is connected to the inside of the medicine dispensing turntable, and one dust removal channel 2 3 is connected to a hose. It should be noted that the hose is a corrugated tube, which has a certain deformation and recovery ability. The staff can drag the hose to make the dust removal head perform dust collection at different positions.

[0053] In order to better achieve dust collection inside the medicine dispensing turntable, a dust removal disk 9 is also included. The dust removal disk 9 is coaxially arranged with the medicine dispensing turntable and is located inside the medicine dispensing turntable. The dust removal disk 9 is provided with a plurality of dust removal holes 10. The dust removal disk 9 is connected to one of the dust removal channels 2 3 to remove dust inside the medicine dispensing turntable. When the medicine dispensing turntable rotates, the dust removal disk 9 remains relatively still, and the plurality of dust removal holes 10 arranged thereon are evenly arranged to meet the dust collection requirements at any time when the medicine dispensing machine is working.

[0054] The dust removal plate 9 in this embodiment is detachable so that the staff can remove it for cleaning and avoid the dust removal hole 10 being blocked and affecting the dust removal effect. Figure 6 As shown, a connecting seat 11 is provided in the medicine dispensing machine, and the connecting seat 11 and the medicine dispensing turntable are coaxially arranged, and the connecting seat 11 is connected to the dust removal disc 9 through a stepped structure. The dust removal disc 9 can be directly overlapped on the connecting seat 11 through the stepped structure, while maintaining the positioning, meeting the dust collection requirements, and is easy to disassemble and assemble. In some embodiments, in order to ensure the connection stability between the dust removal disc 9 and the connecting seat 11, screws or pins can also be added in the radial direction of the stepped mechanism. Furthermore, the dust removal disc 9 is a gathering structure, and the gathering structure is specifically in the shape of an inverted cone. The dust removal hole 10 is arranged at the large aperture of the gathering structure. Through the dust collection of the dust removal channel 23, the inhaled medicine dust is gathered through the gathering structure, and the small diameter end of the gathering mechanism is connected to the connecting seat 11 through the stepped structure, thereby realizing more efficient centralized collection of medicine dust.

[0055] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
