Description

Technical Field

[0001] This utility model relates to the field of pill processing technology, and in particular to a pill coating thickness closed-loop control spraying machine. Background Technology

[0002] Coating is the process of applying sugar or other film-forming materials to the outer surface of a solid pharmaceutical preparation using specific equipment and a specific process. After drying, it becomes one or more multifunctional protective layers of varying thicknesses and elasticities that adhere tightly to the surface. Currently, coating machines are commonly used to complete the coating of pills.

[0003] However, in existing technologies, most coating machines coat pills by rotating the pills inside the coating pan, allowing the pills to come into contact with the coating liquefaction spray delivered by the nozzle. However, the nozzles on some existing coating machines are installed in fixed positions, resulting in a limited spraying range. In addition, some coating machines tend to cause pills to accumulate downwards inside the pan due to gravity, leading to uneven contact between the pills and the coating liquid, which affects the quality of subsequent processing. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art, where the nozzles on some existing coating machines are installed in fixed positions, resulting in a limited spraying range. At the same time, some coating machines tend to cause pills to accumulate downwards inside the pot due to gravity during use, leading to uneven contact between the pills and the coating liquid, which affects the quality of subsequent processing.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a closed-loop control spraying machine for pill coating thickness, comprising: a machine body; an inner cavity formed on the inner wall of the machine body, wherein an inclined air outlet is formed on one side of the inner wall of the inner cavity; and further comprising:

[0007] A storage plate is movably embedded inside the body. The surface of the storage plate has multiple round holes. A positioning shaft is symmetrically located on one side of the body. Two protrusions are sleeved on the surface bearings of the positioning shafts. The two protrusions are movably connected to the surface of the storage plate. A drying tube is located on one side of the body and communicates with the inner cavity.

[0008] Preferably, a drive motor is mounted on one side surface of the machine body via a frame, and a mounting bracket is provided at the output end of the drive motor.

[0009] The technical effect of adopting the above-mentioned further solution is that when the drive motor on the surface of the machine body is working, it drives the mounting bracket on the surface of the output end to rotate, and at the same time the output shaft is connected to the inside of the machine body with the sealing sleeve.

[0010] Preferably, the surface of the mounting bracket is provided with a plurality of arc-shaped inclined plates, and the plurality of arc-shaped inclined plates are slidably connected to the surface of the arc-shaped plates.

[0011] The technical effect of adopting the above-mentioned further solution is that when the mounting frame rotates, it drives the arc-shaped inclined plate to slide along the surface of the arc plate, thereby moving the pill.

[0012] Preferably, the surface hinge of the machine body is provided with a door, and the surface of the door is provided with an observation frame.

[0013] The technical advantage of adopting the above-mentioned further solution is that the box door on the surface of the machine body facilitates the taking and putting of pills, and the internal coating process can be observed through the observation frame.

[0014] Preferably, a mounting box is provided on the surface of the door away from the machine body, and a worm gear is provided inside the mounting box.

[0015] The technical effect of adopting the above-mentioned further solution is that the worm gear is positioned by the mounting box on the surface of the door.

[0016] Preferably, a transmission pipe is provided on the surface bearing at the center of the box door, and a nozzle is provided at one end of the transmission pipe.

[0017] The technical effect of adopting the above-mentioned further solution is that the transfer tube is positioned by the box door, the coating liquid is transferred by the transfer tube, and it is sprayed out by the nozzle to contact the pill. At the same time, the transfer tube is connected to the inside of the machine body with the sealing sleeve.

[0018] Preferably, the surface of the transmission tube is provided with a worm gear, which meshes with a worm.

[0019] The technical effect of adopting the above-mentioned further solution is that, by meshing the worm gear and worm on the surface of the transmission pipe, rotating the worm causes the entire transmission pipe to be selected, changing the spray direction of the nozzle and improving the applicability of the device.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In this utility model, the drive motor is started, causing the arc-shaped inclined plate on the surface of the mounting frame to move along the arc-shaped plate surface, which moves the pills at the bottom. In conjunction with the nozzle on the surface of the transmission pipe, the coating liquid is atomized and comes into contact with the pills on the surface of the arc-shaped plate inside the machine body, so that the pills are fully and evenly in contact with the coating liquid. At the same time, gas is transmitted through the drying pipe and transmitted through the inner cavity surface to perform uniform drying work during the pill coating process.

[0022] 2. In this utility model, when the box door is closed, the coating process inside can be observed through the observation frame. When the worm gear inside the installation box is rotated, the meshing worm wheel is driven to rotate, causing the transmission pipe to drive the nozzle to tilt around the transmission pipe as a fixed point, thereby expanding the spraying range of the coating liquid, improving the applicability of the device, and making it easier to coat the pills evenly.

[0029] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] Example 1, such as Figures 1-4 As shown, this utility model provides a closed-loop control spraying machine for pill coating thickness, including: a machine body 1; an inner cavity 101, which is formed on the inner wall of the machine body 1, and an inclined air outlet 1011 is formed on one side of the inner wall of the inner cavity 101; it also includes: an arc-shaped plate 102, which is disposed on the inner wall of the machine body 1, and an outlet 1021 is formed on the surface of the arc-shaped plate 102; a partition 103 is disposed on the inner wall of the machine body 1, and one side surface of the partition 103 is disposed on the surface of the arc-shaped plate 102; a storage plate 104, which is movably embedded in the interior of the machine body 1, and a plurality of round holes 1041 are formed on the surface of the storage plate 104; a positioning shaft 105 is disposed symmetrically on one side surface of the machine body 1, and two protrusions 1051 are movably connected to the surface of the storage plate 104 on the surface of the two positioning shafts 105; a drying tube 106 is disposed on one side surface of the machine body 1, and the drying tube 106 is connected to the inner cavity 101.

[0032] In this embodiment, the drive motor 107 is started, causing the arc-shaped inclined plate 1072 on the surface of the mounting bracket 1071 to move along the surface of the arc-shaped plate 102, thus agitating the pills at the bottom. In conjunction with the nozzle 2031 on the surface of the transmission pipe 203, the coating liquid is atomized and comes into contact with the pills on the surface of the arc-shaped plate 102 inside the machine body 1, ensuring that the pills are fully and evenly in contact with the coating liquid. At the same time, gas is transmitted through the drying pipe 106 and through the inner cavity 101 on the surface of the inner cavity 101, so as to perform uniform drying work during the pill coating process.

[0033] In Example 2, a drive motor 107 is mounted on one side surface of the machine body 1 via a frame. A mounting bracket 1071 is mounted on the output end of the drive motor 107. Multiple arc-shaped inclined plates 1072 are mounted on the surface of the mounting bracket 1071. The multiple arc-shaped inclined plates 1072 are slidably connected to the surface of the arc-shaped plates 102. A door 2 is mounted on the surface of the machine body 1 via a hinge. An observation frame 201 is mounted on the surface of the door 2. A mounting box 202 is mounted on the surface of the door 2 away from the machine body 1. A worm gear 2021 is mounted inside the mounting box 202. A transmission pipe 203 is mounted on the bearing at the center of the door 2. A nozzle 2031 is mounted on one end of the transmission pipe 203. A worm wheel 2032 is mounted on the surface of the transmission pipe 203. The worm wheel 2032 meshes with the worm gear 2021.

[0034] In this embodiment, when the box door 2 is closed, the coating process inside can be observed through the observation frame 201. When the worm gear 2021 inside the mounting box 202 is rotated, the meshing worm wheel 2032 is driven to rotate, so that the transmission pipe 203 drives the nozzle 2031 to tilt around the transmission pipe 203 as a fixed point, thereby expanding the spraying range of the coating liquid, improving the applicability of the device, and making it easier to coat the pills evenly.

[0035] Working Principle: In use, the pills are placed on the surface of the mounting box 202 by opening the box door 2. The box door 2 is then closed, and the drive motor 107 is started. This causes the arc-shaped inclined plate 1072 on the surface of the mounting bracket 1071 to move along the surface of the arc plate 102, agitating the pills at the bottom. Simultaneously, the spray nozzle 2031 on the surface of the transfer pipe 203 atomizes the coating liquid, bringing it into contact with the pills on the surface of the arc plate 102 inside the machine body 1. This ensures the pills are fully and evenly coated with the coating liquid. At the same time, gas is transmitted through the drying pipe 106 and through the inner cavity 101, ensuring even drying during the pill coating process. Furthermore, the coating process can be observed through the observation frame 201 when the box door 2 is closed. When the worm gear 2021 inside the rotating installation box 202 is rotated, the meshing worm wheel 2032 is driven to rotate, causing the transmission pipe 203 to drive the nozzle 2031 to tilt around the transmission pipe 203 as a fixed point, thereby expanding the spraying range of the coating liquid, improving the applicability of the device, and making it easier to coat the pills evenly. After the work is completed, the protrusion 1051 on the surface of the positioning shaft 105 is rotated to release the restriction on the storage plate 104. By pulling out the storage plate 104, the broken pills collected on the surface are recovered. At the same time, the box door 2 is opened to directly spray water to clean the inside, clean the coating liquid that is attached to the inside, and then discharge it through the drain 1021 and the round hole 1041 for subsequent reprocessing.

[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
