Description

Technical Field

[0001] This utility model relates to the field of effervescent tablet processing technology, and in particular to a nozzle for cleaning effervescent tablet packaging. Background Technology

[0002] During the production of effervescent tablets, after compression molding, a mixture of citric acid and sodium bicarbonate powder (with a particle size of 50-200μm) will remain on the surface. During the process of conveying to the packaging equipment, secondary dust will be generated due to mechanical vibration (the amount of dust measured in the industry can reach 0.5%-1.2% of the tablet weight). If this dust enters the packaging sealing process, it will cause a decrease in the adhesion strength of the heat-sealed parts. To address this, compressed air is usually used to blow away the surface of the effervescent tablets.

[0003] However, most nozzles in the existing technology use a single airflow direct injection method. Although it can remove some dust, the airflow impact can easily cause the edges of the effervescent tablets to break apart (especially for low-hardness tablets). In addition, there is a lack of dust guiding mechanism, and the blown dust can easily re-adhere under the action of airflow vortex. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a nozzle for cleaning effervescent tablet packaging, which solves the technical problem that the nozzles in the prior art lack a dust guiding mechanism and are prone to secondary adhesion, and has the advantage of effectively reducing the dust re-adhesion rate.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a nozzle for cleaning effervescent tablet packaging, including a conveying platform. The conveying platform is equipped with an air-blowing nozzle mechanism for removing dust from the surface of the effervescent tablets. An auxiliary dust-suppressing mechanism is set inside the conveying platform. During the horizontal movement of the effervescent tablet body on the conveying platform, the air-blowing nozzle mechanism blows air to clean the surface of the effervescent tablet body. At the same time, the auxiliary dust-suppressing mechanism suppresses dust in the cleaned area. The air-blowing nozzle mechanism includes conveying rollers symmetrically arranged at both ends of the conveying platform. A perforated conveyor belt is set between the two conveying rollers. A conveying motor for driving the conveying rollers is fixedly installed on the outside of the conveying platform. A lifting bracket is fixedly installed on the conveying platform. A gas nozzle is fixedly installed on the lifting bracket. An air inlet is set at the upper end of the gas nozzle. During the conveying of the effervescent tablets, the operator connects the external air pipe to the air inlet. Subsequently, the gas is sprayed downward through the gas nozzle, thereby cleaning the surface of the effervescent tablets by blowing air.

[0006] Preferably, the auxiliary dust suppression mechanism includes a dust suction platform fixedly installed inside the material conveying platform. The dust suction platform has several circular through holes. A suction air pump is fixedly installed on the material conveying platform. When the suction air pump is powered on, it will suck the dust in the air near the dust blowing and cleaning area into the interior of the dust suction platform.

[0007] Preferably, the cross-sectional area of ​​the gas nozzle increases sequentially from top to bottom, and the gas nozzle has a main air jet channel and an auxiliary air jet channel inside. Through cooperation with the lifting bracket, the area of ​​air jet cleaning can be automatically adjusted.

[0008] Preferably, the auxiliary channel is inclined, with an angle of 45 degrees between the auxiliary channel and the main jet channel. The airflow ejected from the auxiliary channel forms an inclined air curtain, which can effectively prevent the blown-off dust from re-attaching.

[0009] Preferably, the dust suction platform has a rectangular cavity inside, and a circular through hole is connected to the rectangular cavity. When the suction pump is powered on, a negative pressure is formed inside the rectangular cavity.

[0010] Preferably, the circular through holes are provided in two sets, which are respectively opened on the upper and lower sides of the dust suction platform. During the dust suction process, the surface of the perforated conveyor belt can also be cleaned at the same time.

[0011] By employing the above technical solution, this utility model provides a nozzle for cleaning effervescent tablet packaging, which has at least the following beneficial effects:

[0012] 1. This utility model, by setting up an air blowing nozzle mechanism, adopts a dual-channel nozzle design of "main airflow vertical cleaning + auxiliary airflow inclined air curtain". The high-pressure main airflow directly impacts the surface of the effervescent tablet, which can effectively peel off the attached dust. At the same time, the low-pressure auxiliary airflow forms an air curtain wall at a 45° angle, forcing the blown dust to move in a directional direction along the inclined direction. Then, combined with the negative pressure collection of the dust collection platform, it can greatly reduce the re-adhesion rate of dust and greatly improve the cleaning effect.

[0013] 2. This utility model achieves adaptive optimization of the cleaning system by setting up an air blowing nozzle mechanism and linking the adjustable gas nozzle with negative pressure dust collection. The gradually changing cross-sectional area design of the gas nozzle, combined with the lifting bracket, can flexibly adjust the spray coverage range to meet the cleaning needs of effervescent tablets of different sizes.

[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 protection scope of the present utility model.

[0021] Example 1

[0022] Most nozzles in existing technologies use a single airflow direct injection method. While this can remove some dust, the airflow impact easily causes the edges of effervescent tablets to disintegrate (especially for low-hardness tablets), and there is a lack of dust guiding mechanism, allowing the dispersed dust to easily re-adhere under the action of airflow vortices. To address this technical deficiency in existing technologies, such as... Figures 1-4 As shown, this embodiment proposes a nozzle for cleaning effervescent tablet packaging. It adopts a dual-channel nozzle design of "main airflow vertical cleaning + auxiliary airflow inclined air curtain", which can greatly reduce the dust re-adhesion rate. The nozzle conveying platform 1 is equipped with an air blowing nozzle mechanism 3 for removing dust from the surface of the effervescent tablet. An auxiliary dust suppression mechanism 4 is set inside the conveying platform 1. During the horizontal movement of the effervescent tablet body 2 on the conveying platform 1, the air blowing nozzle mechanism 3 will blow air to clean the surface of the effervescent tablet body 2. At the same time, the auxiliary dust suppression mechanism 4 will perform dust suppression treatment on the cleaned area.

[0023] Specifically, the air blowing nozzle mechanism 3 includes conveying rollers 301 symmetrically arranged at both ends of the conveying platform 1, a perforated conveyor belt 302 arranged between the two conveying rollers 301, a conveying motor 303 for driving the conveying rollers 301 fixedly installed on the outside of the conveying platform 1, a lifting bracket 304 fixedly installed on the conveying platform 1, and a gas nozzle 305 fixedly installed on the lifting bracket 304. The cross-sectional area of ​​the gas nozzle 305 increases sequentially from top to bottom. The gas nozzle 305 has a main air jet channel 306 and an auxiliary channel 307 inside, which, through interaction with the lifting bracket 304, allows for air jetting. The cooperation of the lowering bracket 304 can automatically adjust the area of ​​air jet cleaning. The upper end of the gas nozzle 305 is provided with an air inlet 308. During the delivery of effervescent tablets, the staff will connect the external air pipe to the air inlet 308. Then, the gas will be sprayed downward through the gas nozzle 305 to clean the surface of the effervescent tablets. The auxiliary channel 307 is set at an angle of 45 degrees with the main air jet channel 306. The airflow sprayed from the auxiliary channel 307 will form an inclined air curtain wall, which can effectively prevent the secondary adhesion of blown-off dust.

[0024] Specifically, the auxiliary dust suppression mechanism 4 includes a dust suction platform 401 fixedly installed inside the conveying platform 1. The dust suction platform 401 has several circular through holes 402. A rectangular cavity is opened inside the dust suction platform 401. The circular through holes 402 are connected to the rectangular cavity. When the suction pump 403 is powered on, it will form a negative pressure inside the rectangular cavity. The suction pump 403 is fixedly installed on the conveying platform 1. When the suction pump 403 is powered on, it will suck the dust in the air near the dust blowing cleaning area into the dust suction platform 401. There are two sets of circular through holes 402. The two sets of circular through holes 402 are respectively opened on the upper and lower sides of the dust suction platform 401. During the dust suction process, the surface of the perforated conveyor belt 302 can also be cleaned at the same time.

[0025] As can be seen from the above, after the effervescent tablet body 2 is pressed, it falls onto the perforated conveyor belt 302 and moves horizontally along with the perforated conveyor belt 302, thereby conveying the effervescent tablet body 2 to the packaging equipment for heat sealing packaging.

[0026] During this process, when the effervescent tablet body 2 passes under the gas nozzle 305, high-pressure gas enters the interior of the gas nozzle 305 through the air inlet 308. Next, a portion of the gas is ejected vertically downward through the main jet channel 306 (pressure 0.1MPa), thereby peeling off the dust on the surface of the effervescent tablet body 2. Another portion of the gas is ejected obliquely through the auxiliary channel 307 (0.02MPa), thereby forming an air curtain on the surface of the effervescent tablet body 2. This causes the dispersed dust to move directionally along the oblique direction of the air curtain, effectively preventing secondary adhesion.

[0027] Moreover, at the same time, the suction pump 403 will create negative pressure inside the dust suction platform 401, thereby collecting the blown dust in time, which can also prevent the dust from adhering again to a certain extent and improve the effect of air blowing cleaning.

[0028] This embodiment employs a dual-channel nozzle design with a blowing nozzle mechanism 3 and a dual-channel nozzle structure of "vertical cleaning with main airflow + inclined air curtain with auxiliary airflow". The high-pressure main airflow directly impacts the surface of the effervescent tablet, effectively removing attached dust. Simultaneously, the low-pressure auxiliary airflow forms an air curtain at a 45° angle, forcing the blown dust to move directionally along the inclined direction. Combined with the negative pressure collection of the dust collection platform 401, the re-adhesion rate of dust is greatly reduced, significantly improving the cleaning effect. Furthermore, this embodiment achieves adaptive optimization of the cleaning system through the linkage between the adjustable gas nozzle 305 and the negative pressure dust collection by setting up the blowing nozzle mechanism 3. The gradually changing cross-sectional area design of the gas nozzle 305, combined with the lifting bracket 304, allows for flexible adjustment of the spray coverage range, thereby adapting to the cleaning needs of effervescent tablets of different sizes.

[0029] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
