Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, and in particular to an additive feeding device. Background Technology

[0002] In medicine, auxiliaries (or additives) are defined as excipients and additives used in the production of pharmaceuticals and the preparation of prescriptions. They encompass all materials other than the main active ingredient of the drug and are essential components of pharmaceutical formulations. In industrial production, additives are auxiliary chemicals added to improve production processes, increase product quality and yield, or to impart specific application properties to products.

[0003] Currently, in industrial production, it is necessary to weigh different additives. After weighing multiple additives, they are placed in a stirring mechanism for mixing. However, in the existing technology, the weighing of additives is generally done manually. The weighing cylinder is placed on an electronic scale, and then the additive is put into the cylinder. This method not only consumes a lot of labor and increases labor costs, but also has low efficiency, which is not conducive to large-scale production. Based on this, we propose an additive feeding device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides an additive feeding device, which, after development, can effectively solve the problems mentioned in the background art.

[0005] The technical solution of this utility model is as follows:

[0006] An additive feeding device includes a frame, diaphragm pumps, anti-drip valves, and a weighing mechanism. A plurality of diaphragm pumps are mounted on the top surface of the frame, and a plurality of anti-drip valves corresponding to the diaphragm pumps are mounted in the inner center of the frame. A plurality of weighing mechanisms corresponding to the anti-drip valves are mounted on the bottom of the frame. The diaphragm pumps and anti-drip valves are connected via pipes. The liquid outlet of the anti-drip valve is aligned with the weighing mechanism.

[0007] The weighing mechanism includes a weighing plate, a connecting frame, and a weighing sensor. Several base plates are welded to the bottom of the frame. The weighing sensor is fixedly installed on the top surface of the base plate by screws. The top surface of the weighing sensor is connected to the connecting frame, and the top surface of the connecting frame is welded to the weighing plate.

[0008] Furthermore, adjacent weighing plates do not contact each other, the weighing plates do not contact the frame, the weighing sensors are fixed to the connecting frame by screws, and a material cylinder is placed on the top surface of the weighing plate.

[0009] Furthermore, the diaphragm pump is fixedly installed on the top surface of the frame by screw connection. The inlet end of the diaphragm pump is equipped with an inlet pipe, and the outlet end of the diaphragm pump is connected to the inlet end of the anti-drip valve through a pipe. The outlet end of the anti-drip valve is aligned with the counterweight plate.

[0010] Furthermore, the anti-drip valve is fixedly installed on the frame via a connecting block. The connecting block has an L-shaped structure and a mounting hole at its bottom. The lower part of the anti-drip valve is inserted into the mounting hole and fixedly connected by a nut. The top of the connecting block has two strip holes, and the connecting block is fixedly installed on the frame via the two strip holes and bolts.

[0011] Furthermore, the frame is made of aluminum alloy or stainless steel.

[0012] Furthermore, the number of diaphragm pumps, anti-drip valves, and weighing mechanisms is fourteen.

[0013] Furthermore, an arc-shaped limiting ring is welded to the top surface of the weighing plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] Compared with existing technologies, this utility model, by incorporating a frame, diaphragm pump, anti-drip valve, and weighing mechanism, enables simultaneous weighing of multiple material cylinders, significantly improving production efficiency. Furthermore, the compact installation of the diaphragm pump, anti-drip valve, and weighing mechanism on the frame reduces the device's footprint and facilitates user operation. In addition, by pumping the liquid with the diaphragm pump, controlling the liquid flow with the anti-drip valve, and simultaneously weighing with the weighing mechanism, the device achieves precise and automatic weighing of the liquid without manual operation, greatly saving labor and reducing labor costs. Moreover, using this device is beneficial for large-scale production, offering a high degree of automation and strong practicality. Attached Figure Description

Detailed Implementation

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0023] like Figure 1-5 As shown,

[0024] An additive feeding device includes a frame 1, a diaphragm pump 2, an anti-drip valve 3, and a weighing mechanism 4. The top surface of the frame 1 is provided with a plurality of diaphragm pumps 2, and the inner center of the frame 1 is provided with a plurality of anti-drip valves 3 corresponding to the plurality of diaphragm pumps 2. The bottom of the frame 1 is provided with a plurality of weighing mechanisms 4 corresponding to the plurality of anti-drip valves 3. The diaphragm pumps 2 and the anti-drip valves 3 are connected by pipes. The outlet end of the anti-drip valve 3 is aligned with the weighing mechanism 4. The weighing mechanism 4 includes a weighing plate 5, a connecting frame 6, and a weighing sensor 7. A plurality of base plates 8 are welded to the bottom of the frame 1, and the weighing sensor 7 is fixedly installed on the top surface of the base plate 8 by screws. The top surface of the weighing sensor 7 is connected to the connecting frame 6, and the top surface of the connecting frame 6 is welded with the weighing plate 5. In this application, a controller is provided at the top right end of the frame 1. The weighing sensor 7 is connected to the controller via a signal, and the diaphragm pump 2 and the anti-drip valve 3 are electrically connected to the controller. It can be understood that during feeding, the liquid will enter the feed cylinder 9. At this time, the weighing sensor 7 can effectively weigh the liquid. After the weighing sensor 7 transmits the weighing information signal to the controller, when the weight of the liquid reaches the set value, the controller will control the diaphragm pump 2 and the anti-drip valve 3 to stop. Generally, the diaphragm pump 2 is stopped first, and then the anti-drip valve 3 is stopped. It is worth mentioning that the weight of the feed cylinder 9, the weighing plate 5, and the connecting frame 6 is the "non-tare" weight. The weight measured by the weighing sensor 7 will be reduced by this part to obtain the weight of the liquid.

[0025] In a preferred embodiment, adjacent weighing plates 5 do not contact each other, and the weighing plates 5 do not contact the frame 1. The weighing sensor 7 is fixed to the connecting frame 6 by screws, and a material cylinder 9 is placed on the top surface of the weighing plate 5. It can be understood that the bottom end of the weighing sensor 7 is the base plate 8, and the top end is the weighing plate 5 and the connecting frame 6. The weighing plate 5 does not contact other components, thus enabling accurate measurement. Each weighing mechanism 4 is independently set up, and there is no interference between the weighing mechanisms 4. Each group of diaphragm pump 2, anti-drip valve 3, and weighing mechanism 4 can weigh different types of additives, thereby greatly improving production efficiency.

[0026] In a preferred embodiment, the diaphragm pump 2 is fixedly mounted on the top surface of the frame 1 by screws. An inlet pipe 10 is installed at the inlet end of the diaphragm pump 2, and the outlet end of the diaphragm pump 2 is connected to the inlet end of the anti-drip valve 3 via a pipe. The outlet end of the anti-drip valve 3 is aligned with the counterweight plate 5. It can be understood that the inlet pipe 10 is mainly connected to an external material tank via a pipe, allowing for the addition and weighing of additives after the diaphragm pump 2 is started.

[0027] In a preferred embodiment, the anti-drip valve 3 is fixedly mounted on the frame 1 via a connecting block 11. The connecting block 11 has an L-shaped structure, with a mounting hole at its bottom. The lower part of the anti-drip valve 3 is inserted into the mounting hole and fixedly connected by a nut. The top of the connecting block 11 has two slotted holes 12, and the connecting block 11 is fixedly mounted on the frame 1 via the two slotted holes 12 and bolts. It can be understood that by providing the L-shaped connecting block 11, the anti-drip valve 3 can be effectively installed, and the vertical height of the anti-drip valve 3 can be adjusted via the screw connection of the slotted holes 12, facilitating the use of material cylinders 9 of different specifications.

[0028] In a preferred embodiment, the frame 1 is made of aluminum alloy or stainless steel.

[0029] In a preferred embodiment, fourteen diaphragm pumps 2, anti-drip valves 3, and weighing mechanisms 4 are provided. The presence of multiple diaphragm pumps 2, anti-drip valves 3, and weighing mechanisms 4 allows for the simultaneous weighing of different types of additives, significantly improving efficiency.

[0030] Furthermore, an arc-shaped limiting ring 13 is welded to the top surface of the weighing plate 5. This facilitates the limiting of the material cylinder 9.

[0031] The working principle of this utility model is as follows: After the diaphragm pump 2 is started, the liquid material can be drawn and transported to the anti-drip valve 3 through the diaphragm pump 2. The liquid material drips into the material cylinder 9 through the anti-drip valve 3. At this time, the liquid material can be effectively weighed by the weighing sensor 7, realizing the automated feeding and weighing work.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
