Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical equipment, in particular to an oscillating screening device for pharmaceutical use. Background Art

[0002] When making medicines, the raw materials of the medicines must first be screened. Usually, artificial vibration or mechanical vibration is used to screen out excess impurities in the raw materials of the medicines. At the same time, raw materials of different sizes are also screened to make subsequent processing more convenient.

When the screening box body vibrates, the large particles of the pharmaceutical raw materials poured in the screening box body are screened and sent away through the inclined surfaces, thereby reducing the number of screening times, and directly performing fine screening at one time. The large particles of raw materials during screening can be directly discharged, which is convenient for re-grinding the large particles of raw materials and can also improve the screening efficiency. By increasing the negative pressure and the vibration source, the small particles of raw materials during screening can quickly enter the collection area without clogging the screen, thereby reducing the generation of dust during screening, and the small particles of raw materials screened out can be quickly settled and collected to reduce the impact on the air.

[0004] The existing technology has the following problems:

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 , Figure 2 As shown, a pharmaceutical shaking screening device includes a box body 1, a transparent protective cover 2 is rotatably connected to the top rear end of the box body 1, a feed port 3 is provided on the top of the transparent protective cover 2, a replacement mechanism 4 is movably connected to the upper end of the inner wall of the box body 1, an shaking mechanism 6 is fixedly connected to the front side of the inner wall of the box body 1, and limiting slide grooves 5 are provided on the left and right sides of the inner wall of the box body 1.

[0027] It should be noted that, through the replacement mechanism 4, the screening filter 42 can be replaced quickly and conveniently, so that the screening efficiency is greatly improved. Through the oscillation mechanism 6, the screening box 41 can vibrate to a certain extent, thereby achieving the effect of up and down oscillation. At the same time, the transparent protective cover 2 can prevent the raw materials from being shaken out during the oscillation, and the screening degree of the raw materials can also be observed.

[0028] like Figure 2-Figure 4 As shown, the replacement mechanism 4 includes a screening box 41, the outer surface of the screening box 41 is movably connected to the upper end of the inner wall of the box body 1, and sliders 43 are fixedly connected to the middle positions of the left and right sides of the outer surface of the screening box 41, and four support plates 45 are fixedly connected around the middle of the inner wall of the screening box 41, and the tops of the four support plates 45 are overlapped with screening filters 42. Inner grooves 47 are opened at the four corners of the screening box 41, and the inner wall of the inner groove 47 is movably connected to a fixed slider 44, and a pull rod 46 is fixedly connected to the end of the top of the fixed slider 44 away from the screening filter 42, and three springs 48 are fixedly connected to the side of the fixed slider 44 away from the screening filter 42, and the ends of the three springs 48 away from the fixed slider 44 are fixedly connected to the side of the inner wall of the inner groove 47 away from the fixed slider 44.

[0029] It should be noted that, by pulling the four pull rods 46 outward, the fixed slider 44 is driven to move outward, thereby compressing the three springs 48. At this time, the screening filter 42 is lifted upward to take out the screening filter 42, and the screening filter 42 is replaced with a screening filter 42 with a suitable hole size. The screening filter 42 is then placed inside the screening box 41 so that the screening filter 42 is placed on the surrounding support plates 45. The pull rod 46 is then released, and under the action of the spring 48, the fixed sliders 44 at the four corners are moved inward, thereby fixing the four corners of the screening filter 42, thereby completing the rapid replacement of the screening filter 42, and thus pharmaceutical raw materials of different sizes can be screened.

[0030] like Figure 4 As shown, the height of the fixed slider 44 is consistent with the height of the inner groove 47 , and the distance between the bottom surface of the inner groove 47 and the support plate 45 is consistent with the thickness of the outer ring portion of the screening screen 42 .

[0031] It should be noted that the fixing slider 44 slides smoothly to the four corners of the outer circle of the screening screen 42, thereby achieving a better fixing effect.

[0032] like Figure 2 , Figure 5 As shown, the shape of the slider 1 43 is T-shaped, and the area of ​​the slider 1 43 is consistent with the area of ​​the limiting sliding groove 5.

[0033] It should be noted that the T-shape ensures that the slider 43 can move up and down smoothly while also ensuring that it will not shake easily, thereby affecting the movement.

[0034] like Figure 2 , Figure 3 As shown, the width of the pull rod 46 is consistent with the width of the top of the inner groove 47 , and the height of the pull rod 46 is much greater than the thickness of the top of the inner groove 47 .

[0035] It should be noted that by smoothly pulling the pull rod 46 , the fixed slider 44 can slide out smoothly, thereby achieving a fixing effect.

[0036] like Figure 1 , Figure 2 , Figure 5 As shown, the oscillation mechanism 6 includes a motor 61 and two fixed plates 66, the front side of the motor 61 is fixedly connected to the lower end of the front side of the inner wall of the box body 1, the front and rear side surfaces of the two fixed plates 66 are fixedly connected to the middle of the front and rear sides of the inner wall of the box body 1, the output end of the motor 61 is fixedly connected to a rotating shaft 69, the outer surface of the rotating shaft 69 is fixedly connected to a rotating wheel 62, the rear end of the rotating shaft 69 is rotatably connected to the lower end of the rear side of the inner wall of the box body 1, the upper end of the outer surface of the rotating wheel 62 is overlapped with a moving plate 63, the upper surface of the moving plate 63 is fixedly connected with four striking rods 67 in a rectangular array, the outer surfaces of the striking rods 67 are movably connected with springs 2 65, the lower end of the springs 2 65 is fixedly connected to the upper surface of the moving plate 63, the upper end of the springs 2 65 is fixedly connected to the lower surface of the fixed plate 66, the left and right side surfaces of the moving plate 63 are fixedly connected with sliders 2 64, and through holes 68 are opened on the front and rear sides of the tops of the two fixed plates 66.

[0037] It should be noted that starting the motor 61 will drive the rotating shaft 69 to rotate clockwise, and then drive the rotating wheel 62 to rotate clockwise. The movement trajectory of the rotating wheel 62 at the farthest point from the motor 61 is elliptical, which will drive the movable plate 63 to move up and down, and then drive the four striking rods 67 to move up and down through the through hole 68, thereby compressing the spring 2 65. At this time, the through hole 68 will drive the screening box 41 to move up and down. At the same time, under the influence of the spring 2 65, the effect of up and down oscillation is achieved. With the use of the screening filter 42, the pharmaceutical raw materials can be screened to a certain extent. The larger ones will be located on the screening filter 42, and the smaller ones will fall to the bottom of the screening box 41.

[0038] like Figure 2 , Figure 5 As shown, the shape of the slider 2 64 is T-shaped, and the area of ​​the slider 2 64 is consistent with the area of ​​the limiting sliding groove 5 .

[0039] It should be noted that the T-shape ensures that the slider 2 64 can move up and down smoothly while also ensuring that it will not shake easily, thereby affecting the movement.

[0040] like Figure 5 As shown, the upper end of the striking rod 67 is in a hemispherical block shape, and the diameter of the outer surface of the striking rod 67 is slightly smaller than the diameter of the inner wall of the through hole 68 .

[0041] It should be noted that the striking rod 67 passes through the through hole 68 smoothly, and the upper end of the striking rod 67 has a certain toughness, so the vibration generated when striking is also stronger.

[0042] The working principle of the utility model is as follows: the four pull rods 46 are pulled outward, thereby driving the fixed slider 44 to move outward, thereby compressing the three springs 48, and at this time, the screening filter 42 is lifted upward to take out the screening filter 42, and the screening filter 42 with a suitable hole size is replaced, and then the screening filter 42 is placed inside the screening box 41, so that the screening filter 42 is placed on the supporting plates 45 around it, and then the pull rod 46 is loosened, and under the action of the spring 48, the fixed sliders 44 at the four corners are moved inward, and then the four corners of the screening filter 42 are fixed, thereby completing the rapid replacement of the screening filter 42, and pharmaceutical raw materials of different sizes can be screened, and the transparent protective cover 2 is rotated downward so that the transparent protective cover 2 is placed on the top of the box body 1, and then the pharmaceutical raw materials are added from the feed inlet 3. The pharmaceutical raw materials are then started, and the rotating shaft 69 is driven to rotate clockwise, and the rotating wheel 62 is driven to rotate clockwise. The motion trajectory of the rotating wheel 62 at the farthest point from the motor 61 is elliptical, which will drive the movable plate 63 to move up and down, and then drive the four striking rods 67 to move up and down through the through hole 68, so that the spring 2 65 is compressed. At this time, the through hole 68 will drive the screening box 41 to move up and down. At the same time, under the influence of the spring 2 65, the effect of up and down oscillation is achieved. With the use of the screening filter 42, the pharmaceutical raw materials are screened to a certain extent. The larger ones will be located on the screening filter 42, and the smaller ones will fall to the bottom of the screening box 41. At the same time, the transparent protective cover 2 provided can prevent the raw materials from being shaken out during the oscillation, and the screening degree of the raw materials can also be observed.
