Description

Technical Field

[0001] This utility model relates to the field of dust-free feeding machine technology, specifically a pharmaceutical intermediate feeding device. Background Technology

[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis.

[0003] For example, Chinese utility model patent CN222273541U proposes a high-efficiency dust-free feeding machine, including a frame, a protective shell on top of the frame, a sealed door on the protective shell, a hopper below the frame, a feeding port above the hopper, a baffle rotatably mounted at the edge of the feeding port, a fixed mounting plate on the inner wall of the baffle above the feeding port, support frames on the top walls of both sides of the baffle, an electric push rod below the top wall of the support frame, a fixed mounting plate below the electric push rod, and a blade below the fixed mounting plate. This utility model belongs to the technical field of dust-free feeding machines, specifically referring to a high-efficiency dust-free feeding machine that performs feeding in a sealed state, preventing powder from flying out, reducing raw material waste, and ensuring a safe feeding environment.

[0004] In existing devices, the bagged powder raw materials are manually transported to the feeding port, and then the packaging bag is cut open with a blade to shake the powder raw materials into the feeding port. This feeding method causes a lot of powder to be thrown up when the powder raw materials are shaken into the feeding port, resulting in the loss and waste of raw materials. To address this, we propose a pharmaceutical intermediate feeding device to prevent the powder from flying out. Utility Model Content

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-6This application provides a pharmaceutical intermediate feeding device, including a cleanroom 100, a base 110 at the bottom of the cleanroom 100, a cover 120 rotatably connected to one side of the cleanroom 100, a discharge hopper 140 at the bottom of the cleanroom 100, a suction fan 130 at the top of the cleanroom 100, a feeding port 210 at the bottom inside the cleanroom 100, the feeding port 210 being vertically positioned directly above the discharge hopper 140 and the two being sealed together by a flange, a screen 220 being provided on the inner wall of the feeding port 210, a cutting mechanism 400 penetrating one side of the feeding port 210, a gear 460 meshing on one side of the cutting mechanism 400, and a... A rotating rod 500 is provided, which passes through the feeding port 210. A short rod 510 is provided on one side of the rotating rod 500. A clamping mechanism 300 is provided on the side wall of the dust-free box 100. The clamping mechanism 300 includes a gripper mechanism 310, which includes a base plate 311. Two sets of side plates 312 are fixed to the top of the base plate 311. A claw hook 314 is hinged between each set of side plates 312. An electric push rod 315 is provided to the top of the base plate 311. A horizontal plate 316 is provided to the top of the electric push rod 315. Claw hooks 314 are hinged to both sides of the horizontal plate 316. A bearing seat 313 is fixed to the bottom of the base plate 311. The bearing seat 313 is connected to the clamping mechanism 300 by a bearing.

[0034] During use, the main body is a sealed cleanroom box 100, with a welded base 110 at the bottom for fixing it to the ground. A hinged, openable box cover 120 is installed on the side. A suction fan 130 is installed on the top of the cleanroom box 100 to remove dust generated during feeding. A discharge hopper 140 is connected to the bottom center and connected to a downstream pipe via a flange to discharge the powder. During feeding, first open the box cover 120, place the woven bag containing the intermediate material on top of the feeding port 210, and then activate the electric actuator 315 to move the horizontal plate 316 upwards. Clamp the woven bag, then close the lid 120 and start the suction fan 130 to create a negative pressure environment inside the dust-free box 100 to prevent powder leakage. Then open the cutting mechanism 400. The cutting mechanism 400 rotates and cuts the bottom middle of the woven bag, allowing the middle part inside the woven bag to flow out. At the same time, the cutting mechanism 400 drives the gear 460 meshing on one side to rotate. The rotation of the gear 460 drives the rotating rod 500 and the short rod 510 set on the rotating rod 500 to rotate, hitting the screen 220, causing the screen 220 to shake so that the powder can pass through, thus completing the feeding.

[0035] In some embodiments, the cutting mechanism 400 includes a mounting base 410, a servo motor 420 is fixed to the top of the mounting base 410, a rotating rod 440 is provided at one end of the output shaft of the servo motor 420, the rotating rod 440 passes through the side wall of the cleanroom 100, a blade 450 is provided on one side of the rotating rod 440 located inside the cleanroom 100, and a gear 430 is provided on the outer side of the rotating rod 440 located outside the cleanroom 100.

[0036] During use, the servo motor 420 is fixed to the outside of the cleanroom 100 via the mounting base 410. When feeding materials, the servo motor 420 inside the cutting mechanism 400 is turned on, so that the output shaft of the servo motor 420 drives the rotating rod 440 to rotate and cut the woven bag. The servo motor 420 is located outside the cleanroom 100 to effectively prevent powder from entering the servo motor 420 during use and causing damage to the servo motor 420.

[0037] In some embodiments, a gear 460 meshes with one side of the gear 430, and the gear 460 is fixedly connected to the center hole of the rotating rod 500 via a flat key.

[0038] During use, the servo motor 420 can be turned on. The output shaft of the servo motor 420 drives the rotating rod 440 to rotate, and at the same time, it drives the gear 430 set on the rotating rod 440 to rotate. The rotation of the gear 430 drives the gear 460 meshing on one side to rotate. The rotation of the gear 460 drives the rotating rod 500 set on one side to rotate. During the rotation of the rotating rod 500, the short rod 510 set at its top hits the screen 220. At this time, the screen 220 vibrates, which facilitates the passage of powder. The initial positions of the screens 220 set on the two rotating rods 500 are opposite.

[0039] In some embodiments, the clamping mechanism 300 includes an electric push rod 320, the bottom of which is located at the bottom of the cleanroom 100, and a square tube 330 is fixed to the top of the electric push rod 320. A gripper mechanism 310 is provided on the top of the square tube 330.

[0040] During use, the clamping mechanism 300 includes an electric push rod 320. The bottom of the electric push rod 320 is fixed to the bottom of the cleanroom 100, and the top of the electric push rod 320 is fixedly connected to a square tube 330. The height of the square tube 330 can be controlled by adjusting the extension and retraction of the electric push rod 320, thereby controlling the height of the gripper mechanism 310, which facilitates the clamping of bagged intermediate powders of different specifications.

[0041] In some embodiments, a lead screw 710 is provided inside the square tube 330, and a bearing seat 313 is connected to the lead screw 710. A through groove is provided at the top of the square tube 330, and a T-shaped guide rail 700 is welded to one side of the through groove. A base plate 311 is snapped onto the top of the T-shaped guide rail 700. A steering mechanism 600 is provided on one side of the T-shaped guide rail 700, and the steering mechanism 600 penetrates the side wall of the square tube 330.

[0042] During use, a lead screw 710 is installed inside the square tube 330. A bearing seat 313 is connected to the lead screw 710. A base plate 311 is fixedly connected to the top of the bearing seat 313. The gripper mechanism 310 can slide on the lead screw 710 by rotating the steering mechanism 600. The base plate 311 inside the gripper mechanism 310 is engaged with the T-shaped guide rail 700 installed on the top of the square tube 330, which facilitates the sliding of the gripper mechanism 310 and limits its movement to prevent it from shaking.

[0043] In some embodiments, the steering mechanism 600 includes a first bevel gear 610, a lead screw 710 is provided on one side of the first bevel gear 610, a second bevel gear 620 meshes with one side of the first bevel gear 610, and a handwheel 630 is provided on one side of the second bevel gear 620 through a crossbar passing through the side wall of the square tube 330.

[0044] During use, the steering mechanism 600 includes a handwheel 630. The rotatable handwheel 630 rotates and drives the second bevel gear 620 on one side to rotate. The rotation of the second bevel gear 620 drives the first bevel gear 610 meshing on both sides to rotate, causing the lead screw 710 inside the first bevel gear 610 to rotate. This controls the sliding of the gripper mechanism 310 connected to the bearing at the top of the lead screw 710, thereby adjusting the distance between the two gripper mechanisms 310 to accommodate different specifications of bagged intermediates.

[0045] In some embodiments, the cleanroom 100 has a sealing ring 800 around the opening on one side of the lid 120.

[0046] During use, the cleanroom box 100 is equipped with sealing rings 800 on all four sides of the opening on one side of the lid 120 to prevent powder from leaking out when the device feeds materials after the lid 120 is rotated to close the cleanroom box 100.

[0047] In some embodiments, an arc-shaped groove 230 is provided on one side of the base 110.

[0048] During use, an arc-shaped groove 230 is opened on one side of the base, and an anti-collision pad is installed in the arc-shaped groove 230 to facilitate the staff to put the powder bag into the device and secure it on the anti-collision pad.
