[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-5 The utility model provides a technical solution: a screening mechanism for pharmaceutical production auxiliary materials, comprising a housing 100 and a screening assembly 200 embedded in the housing 100, the screening assembly 200 comprising a fixed plate 210 and a rotary bucket 220 coaxially distributed at the upper and lower ends, the fixed plate 210 being welded in the housing 100 along a horizontal plane direction, a servo motor 230 being mounted on the top of the fixed plate 210, the output end of the servo motor 230 passing through the fixed plate 210 and connected to the rotary bucket 220 through a shaft 240 A plurality of feeding holes 2110 distributed in a circular array are provided on the fixed plate 210 and outside the servo motor 230, an inner baffle plate 2210 which is covered on the outside of the shaft rod 240 and has a conical structure is provided on the inner bottom wall of the rotary bucket 220, a plurality of grinding rollers 2120 which are rotatably installed below the fixed plate 210 and are rotatably fitted to the outer surface of the inner baffle plate 2210, a plurality of discharging holes 2220 are provided at the bottom of the rotary bucket 220, and a screen 250 is installed below the plurality of discharging holes 2220.

[0028] Based on the above-mentioned structural setting, the screening mechanism for auxiliary materials in pharmaceutical production is composed of a shell 100 and a screening assembly 200, wherein the shell 100 provides structural support for the installation of the screening assembly 200 and provides a containing space for the screening operation of the auxiliary materials, and the screening assembly 200 is used to screen and grind the auxiliary materials input into the shell 100. Specifically, during the working process, after the auxiliary materials enter the shell 100, they enter the rotary bucket 220 through a plurality of feed holes 2110. Driven by the servo motor 230, the rotary bucket 220 drives the screens 250 to rotate to realize the screening operation of the auxiliary materials. The auxiliary materials that meet the sieve holes of the screen 250 pass through the screen 250 and are output, while the auxiliary materials that do not meet the sieve holes of the screen 250 are turned over in the rotary bucket 220 as the screen 250 rotates and are assisted by the inner baffle 2210 and a plurality of grinding rollers 212 0 to achieve grinding until it can pass through the screen 250. Finally, the auxiliary materials input into the housing 100 can be output with a particle size that meets the sieve hole requirements of the screen 250. The screening mechanism for auxiliary materials in pharmaceutical production, by arranging a screening component 200 in the housing 100, can drive the rotary bucket 220 and the screen 250 to rotate with the help of a servo motor 230 installed on the fixed plate 210, thereby effectively realizing the screening of the auxiliary materials on the screen 250. At the same time, an inner baffle 2210 is arranged at the bottom of the fixed plate 210. On the one hand, the inner baffle 2210 is covered on the outside of the shaft 240 for protecting the shaft 240. On the other hand, in conjunction with a plurality of grinding rollers 2120 rotatably installed under the fixed plate 210, the auxiliary materials that have not passed through the screen 250 can be ground and processed, thereby increasing the functionality of the equipment and improving the processing efficiency.

[0029] Furthermore, the shell 100 includes a cylinder shell 110 and a first connecting end tube 120 and a second connecting end tube 130 respectively coaxially flange-assembled at both ends of the cylinder shell 110, and the edges of the flanges of the first connecting end tube 120 and the second connecting end tube 130 are provided with a shroud 140 extending vertically inward and can be covered at the port of the cylinder shell 110. Among them, since the present application does not require the use of additional equipment and processes for secondary grinding of auxiliary materials that do not meet the mesh requirements of the screen 250, and can directly realize the integrated operation of screening and grinding, it can be directly assembled on the feed pipe end of the subsequent process, and with the help of the first connecting end tube 120 and the second connecting end tube 130, it is helpful for the assembly operation of the present application, and the design of the shroud 140 further ensures the sealing of the flange connection between the two ends of the cylinder shell 110 and the first connecting end tube 120 and the second connecting end tube 130 respectively.

[0030] Furthermore, a cover 260 that can be mounted on the outside of the servo motor 230 is fixedly mounted on the top of the fixed plate 210, and the top of the cover 260 is set as a conical structure. After the auxiliary material is input into the housing 100, it is input into the rotary bucket 220 through a plurality of feeding holes 2110. The cover 260 provides effective protection for the servo motor 230 to prevent the auxiliary material from contacting the servo motor 230. At the same time, the conical structure on the top of the cover 260 helps the auxiliary material to be discharged and prevents the auxiliary material from accumulating on the top of the cover 260.

[0031] Furthermore, an outer baffle plate 2130 is coaxially welded to the bottom of the fixed plate 210, and the outer wall of the outer baffle plate 2130 is movably fitted with the inner wall of the rotary bucket 220. In particular, since the rotary bucket 220 is rotatably mounted below the fixed plate 210, in order to prevent the auxiliary materials from being output from the gap between the rotary bucket 220 and the fixed plate 210 as the rotary bucket 220 rotates, the outer baffle plate 2130 is provided to effectively prevent the auxiliary materials from overflowing the rotary bucket 220 due to flipping and flying, thereby further ensuring the screening effect.

[0032] Furthermore, a plurality of discharge holes 2220 are distributed in a circular array, and a lifting plate 2230 distributed along the inclined surface direction is welded between any two adjacent discharge holes 2220 and on the inner bottom wall of the rotary bucket 220, and a plurality of lifting plates 2230 are distributed in a circular array. In order to prevent the auxiliary materials from accumulating on the screen 250 and causing the screen 250 to be blocked and thus affecting the screening efficiency, it is preferred that a plurality of lifting plates 2230 are provided, and as the rotary bucket 220 rotates, the auxiliary materials can be stirred and lifted, which helps to improve the screening efficiency of the auxiliary materials.
