Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a feeding device for powdered pharmaceutical intermediates. Background Technology

[0002] As an important raw material for the synthesis of drugs, the accuracy and stability of the feeding of powdered pharmaceutical intermediates directly affect the quality of the final product and the production efficiency.

[0003] Existing powdered pharmaceutical intermediate feeding devices have many shortcomings in their structural and functional design. On the one hand, many devices struggle to achieve quantitative feeding, and the amount of material fed is often difficult to control precisely during the feeding process, resulting in large fluctuations in the amount fed each time. This not only affects the quality stability of the product but may also lead to waste of raw materials and increase production costs.

[0004] On the other hand, the feeding rate of existing devices is usually fixed and cannot be flexibly adjusted according to actual production needs. When producing products of different specifications or when the production process needs to be changed, the existing feeding device cannot quickly adapt to the new feeding rate requirements, requiring the replacement of the entire device or complex modifications. This not only increases equipment costs and operational difficulty but also affects the continuity and efficiency of production. Therefore, those skilled in the art have provided a feeding device for powdered pharmaceutical intermediates to solve the problems mentioned in the background art. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a feeding device for powdered pharmaceutical intermediates, which solves the problems of large fluctuations in the amount of powdered pharmaceutical intermediates fed each time and the inability to adjust the feeding amount of the feeding device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for powdered pharmaceutical intermediates, comprising a support, a material cylinder installed at the bottom of the support, a feeding pipe installed at the bottom of the material cylinder, a solenoid valve installed on the feeding pipe, a limiting ring installed inside the support, a feeding port opened on the upper side of the limiting ring, a feeding port opened on the lower side of the limiting ring, a distributing disc provided inside the limiting ring, distributing grooves equally spaced around the distributing disc, a limiting groove opened on the inner side of the distributing grooves, a push plate provided on the inner side of the distributing grooves, a toothed plate installed on the inner side of the push plate, a limiting hole longitudinally opened in the middle of the distributing disc, a gear rotatably engaged in the limiting hole, a limiting rod installed at the front end of the gear, a turntable slidably inserted on the limiting rod, a positioning rod installed on the side of the turntable facing the distributing disc, a spring installed on the side of the turntable away from the distributing disc, and a motor installed on the rear side of the support.

[0007] Preferably, the feeding pipe passes through the feed inlet and fits against the outer wall of the distribution plate.

[0008] Preferably, the motor is driven and connected to the distributing disc, and the distributing disc is rotatably sleeved with the limiting ring. After the motor starts, the distributing disc rotates, driving the distributing trough to connect with the feeding pipe, thereby achieving the effect of quantitative feeding.

[0009] Preferably, the adjacent toothed plates are staggered, the limiting hole is connected to the inner wall of the limiting groove, the gear is in contact with the toothed plate, rotating the turntable can drive the gear to rotate, and the rotation of the gear can drive the push plate to move in the material distribution groove through the toothed plate, thereby changing the volume of the material distribution groove and thus achieving the effect of changing the material feeding amount.

[0010] Preferably, the spring is sleeved with the limiting rod, one end of the spring is pressed against the front end of the limiting rod, and the other end of the spring is pressed against the turntable. The positioning rod is inserted into the positioning hole, and the changed volume can be fixed by the turntable pressed by the spring after the gear is rotated.

[0011] Compared with the prior art, the present invention provides a feeding device for powdered pharmaceutical intermediates, which has the following beneficial effects: By designing a material cylinder, limiting ring, and feeding pipe on the support frame, and equipping it with a solenoid valve, the initial material feeding can be effectively controlled, laying the foundation for accurate feeding. A motor drives the distribution disc to rotate, and distribution troughs are equidistantly spaced around the disc. When the distribution troughs connect with the feeding pipe, quantitative feeding is achieved, ensuring a relatively consistent amount of material each time and improving feeding accuracy. By creating limiting grooves on the bottom of the distribution troughs and installing toothed plates that mesh with gears, the rotation of the gears drives a push plate to move within the distribution troughs, thereby changing the volume of the troughs. This design allows the feeding amount to be flexibly adjusted according to actual needs, enhancing the applicability of the device. Attached Figure Description
