Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical production, and in particular to a raw material screening device for pharmaceutical production. Background Technology

[0002] Raw material screening equipment used in pharmaceutical production is a device used for particle size analysis and sieving of drug raw materials. It is an indispensable tool in the pharmaceutical industry and is crucial for ensuring drug quality and improving production efficiency. Vibrating screens separate particles of different sizes by vibrating the drug powder up and down on a screen. Cyclone screens use centrifugal force to project particles outwards, which then settle according to particle size on a sieving plate. Airflow screens and tube screens use air to float particles upwards, which then settle on a sieving plate by gravity.

[0003] Existing raw material screening devices for pharmaceutical production typically include key components such as a vibrating screen, screen body, vibrator, and motor. They may also include auxiliary components such as a feed pipe, discharge pipe, support frame, filter box, material handling mechanism, and suction mechanism. For example, Chinese Patent CN217911389U, entitled "A Novel Raw Material Screening Device for Pharmaceutical Production," facilitates the screening of raw materials in pharmaceutical production through an inlet, a first screen, a second screen, a baffle, a screening box, and a collection box. However, before actual use, manual cleaning of the inlet, outlet, and operating area is required to prevent foreign objects from entering the screening machine. It is also necessary to check the screen for damage and ensure all fasteners are secure before operation. This pre-operation preparation is cumbersome and complex, hindering the overall usability of the device. Therefore, this application provides a raw material screening device for pharmaceutical production to meet these needs. Utility Model Content

[0004] The purpose of this application is to provide a raw material screening device for pharmaceutical production, which solves the problem of cumbersome pre-operation inspection steps in the prior art and simplifies the usage steps.

[0005] To achieve the above objectives, this application provides the following technical solution: a raw material screening device for pharmaceutical production, comprising a screening body, wherein a plurality of support plates are arranged inside the screening body, and the top of the support plates is connected to a mounting plate via a vibrating body; a connecting plate is slidably inserted inside the mounting plate, and the same filter plate is arranged on opposite sides of two connecting plates; the screening body contains four filter plates, and the four filter plates are of different models and sizes; material troughs are provided at the top and bottom of the screening body, and a cleaning plate is slidably connected inside the material troughs via an electric slide rail; a discharge port is provided on the side wall of the screening body, and a baffle is rotatably connected inside the discharge port; a collection box is provided on the side wall of the screening body, and the baffle and the collection box are compatible.

[0006] Preferably, the top of the filter plate is provided with a linear slide rail, and a push plate is slidably connected to the linear slide rail. A vertical plate is fixedly installed inside the material trough, and the baffle and the mounting plate are provided with the same compression spring on opposite sides.

[0007] Preferably, a plurality of push rods are fixedly connected to the side wall of the push plate, and the side walls of the plurality of push rods are located on the same plane.

[0008] Preferably, the interior of the mounting plate has a drive roller that rotates via a connecting rod, and a receiving cavity is formed between the two drive rollers.

[0009] Preferably, the mounting plate has a magnetic suction plate inside, and the top and bottom of the plug-in plate are provided with magnetic suction blocks, which are compatible with the magnetic suction plate. The mounting plate also has an anti-slip pad inside.

[0010] Preferably, the top of the screening machine body is provided with a drive slide rail, and the drive slide rail is connected to a sealing cover through a drive component, the sealing cover being able to seal the material trough.

[0011] Preferably, the bottom of the screening machine body is provided with four electric push rods, and the bottom surfaces of the four electric push rods are arranged on the same plane.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model has a reasonable structure. By setting up a cleaning plate, the electric slide rail can be controlled by an external controller before use, so that the electric slide rail can effectively drive the cleaning plate to move. This allows the cleaning plate to effectively clean the material troughs at the top and bottom of the screening machine, thereby ensuring the cleanliness of the material inlet and bottom discharge of the screening machine to a certain extent, thus simplifying the overall use steps and making it more convenient to use.

[0014] 2. In this utility model, by providing a transmission roller and a magnetic suction plate, when the plug-in plate slides into the mounting plate body under force, the transmission roller will directly contact the top and bottom of the plug-in plate. At this time, the rolling structure of the transmission roller can effectively drive the plug-in plate to slide continuously. At the same time, the magnetic suction block on the mounting plate body will contact the magnetic suction plate under the action of magnetic attraction, which can effectively limit the position of the plug-in plate, so that the plug-in plate can be used stably. At the same time, the anti-slip pad can also effectively increase the stability of the plug-in plate during use, thereby improving the stability of the filter plate during installation and use, and avoiding the possibility of the filter plate shifting or tilting during use.

[0028] The following is combined with Figure 1-5 The embodiments shown illustrate the technical solution of this utility model:

[0029] The system includes a screening body 1, which contains several support plates 2. The top of each support plate 2 is connected to a mounting plate 4 via a vibrating body 3. A connector plate 5 is slidably inserted into the mounting plate 4. The same filter plate 6 is provided on opposite sides of two connector plates 5. The screening body 1 contains four filter plates 6, and the four filter plates 6 are of different models and sizes. Material troughs 7 are provided at the top and bottom of the screening body 1. A cleaning plate 9 is slidably connected to the inside of the material troughs 7 via an electric slide rail 8. A discharge port is provided on the side wall of the screening body 1. A baffle 10 is rotatably connected inside the discharge port. A collection box 11 is provided on the side wall of the screening body 1, and the baffle 10 and the collection box 11 are compatible.

[0030] Before use, the screening machine body 1 can be placed directly on a flat surface. The electric slide rail 8 can be controlled by an external controller, which can effectively drive the cleaning plate 9 to move. The cleaning plate 9 can effectively clean the material troughs 7 at the top and bottom of the screening machine body 1, thereby ensuring the cleanliness of the feed inlet and bottom discharge of the screening machine body 1 to a certain extent. The material to be screened can be placed directly into the interior of the screening machine body 1 through the top material trough 7, so that the material comes into contact with the filter plate 6 in sequence. The vibrating machine body 3 can be controlled by an external controller, so that the vibrating machine body 3 can drive the filter plate 6 to vibrate, thereby effectively screening the material. At the same time, the setting of four filter plates 6 can effectively increase the accuracy of screening, and the unsuitable material can be effectively collected through the collection box 11.

[0031] A linear slide rail 12 is provided on the top of the filter plate 6, and a push plate 13 is slidably connected on the linear slide rail 12. A vertical plate 14 is fixedly installed inside the material trough 7, and the same compression spring 15 is provided on the opposite side of the baffle 10 and the mounting plate 4.

[0032] During its use, the electric slide rail 8 can be directly controlled by an external controller, so that the electric slide rail 8 can effectively drive the push plate 13 to move, so that the push plate 13 can push the residual material on the filter plate 6, so that the pushed material comes into contact with the baffle 10. At this time, the pushing force of the baffle 10 will act on the baffle 10, so that the baffle 10 is rotated by force, and then the material trough 7 is in the open state, so that the material can effectively slide along the material trough 7, so that the material falls into the inside of the collection box 11, thereby effectively collecting the material in the collection box 11.

[0033] A number of push rods 16 are fixedly connected to the side wall of the push plate 13, and the side walls of the push rods 16 are located on the same plane.

[0034] When the push plate 13 is subjected to force, the thrust of the push plate 13 can be effectively transmitted to the push rod 16, so that the push rod 16 can move synchronously with the push plate 13, and the push plate 13 can effectively apply its thrust to the baffle 10, so that the baffle 10 rotates under force, thereby changing the distribution angle of the baffle 10, so that the material can fall better, and thus facilitate the collection of the material.

[0035] The interior of the mounting plate 4 is equipped with a drive roller 18 that rotates via a connecting rod 17, and a receiving cavity is formed between the two drive rollers 18.

[0036] When the plug plate 5 is slid into the mounting plate 4 under force, the transmission roller 18 will directly contact the top and bottom of the plug plate 5. At this time, the rolling structure of the transmission roller 18 can effectively drive the plug plate 5 to slide continuously, thereby improving the overall stability of its plug-in fixation.

[0037] The mounting plate 4 has a magnetic suction plate 19 inside, and the top and bottom of the plug-in plate 5 are provided with magnetic suction blocks, which are compatible with the magnetic suction plate 19. The mounting plate 4 also has an anti-slip pad 20 inside.

[0038] When the plug plate 5 slides into the mounting plate 4 under force, the magnetic block on the mounting plate 4 will come into contact with the magnetic plate 19 under the action of magnetic attraction, which can effectively limit the position of the plug plate 5, so that the plug plate 5 can be used stably. At the same time, the anti-slip pad 20 can also effectively increase the stability of the plug plate 5 during use, thereby improving the stability of the filter plate 6 during installation and use, and avoiding the possibility of the filter plate 6 shifting or tilting during use.

[0039] The top of the screening machine body 1 is provided with a drive slide rail 21, and the drive slide rail 21 is connected to a sealing cover 23 through a drive component 22. The sealing cover 23 can seal the material trough 7.

[0040] During storage, the drive slide rail 21 can be directly controlled by an external controller, so that the drive slide rail 21 can effectively drive the sealing cover 23 to move through the drive component 22, so that the sealing cover 23 can be effectively placed above the material trough 7 to seal the material trough 7, thereby effectively ensuring the stability of the screening machine body 1 during use and avoiding the possibility of it shifting.

[0041] The bottom of the screening machine body 1 is equipped with four electric push rods 24, and the bottom surfaces of the four electric push rods 24 are set on the same plane.

[0042] Before use, the electric push rod 24 can be controlled by an external controller, so that the electric push rod 24 can effectively push the screening machine body 1 to rise and fall, thereby effectively adjusting the height of the screening machine body 1 so that it can be placed in a suitable position for use, thereby improving the overall stability of its use.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
