Description

Technical Field

[0001] This utility model relates to the field of weighing device technology, and more specifically, to a weighing device for a powder filling machine. Background Technology

[0002] A drug filling machine is a device specifically designed for automating the filling of pharmaceuticals into containers, particularly suitable for handling powdered drugs. It significantly improves production efficiency and safety in the pharmaceutical industry. To further ensure the accuracy of the drug filling process, the machine is typically equipped with a dedicated weighing device. This device ensures accurate dosage of the drug within the container, avoiding the problems of low efficiency and slow speed in traditional powder weighing. However, existing weighing devices can only achieve efficient coarse feeding during the weighing process, and their performance in fine control is insufficient, making it difficult to meet the high-precision weighing requirements of certain drugs and limiting the application range of the device.

[0003] To address the aforementioned issues, Chinese patent CN214951713U discloses an automatic weighing device for pharmaceutical powder, comprising a discharge pipe, a feeding pipe, a weighing platform, a guiding device, a receiving weighing cylinder, and a receiving hopper. By combining coarse and fine feeding, it meets the high-precision requirements for pharmaceutical powder weighing. However, during the weighing process, the pharmaceutical powder is easily dispersed by airflow, causing some fine particles to adhere to the surface or crevices of the weighing device. This makes it difficult to clean the weighing platform, resulting in powder residue that can easily cause cross-contamination and affect drug quality.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a weighing device for a powder loading machine to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A weighing device for a powder loading machine is installed at the bottom of a conveying mechanism. The device includes a worktable at the bottom of the conveying mechanism, a weighing body at the top of the worktable, a sealing mechanism that cooperates with the conveying mechanism above the weighing body, and a clamping mechanism on the outside of the sealing mechanism.

[0008] Furthermore, to prevent powder from flying around and leaving residue on the weighing body, the double sealing effect of sealant one and sealant two ensures that the powder does not directly contact the weighing body during filling. When the medicine bottle is filled and weighing is performed, the powder will fly around within the sealed space formed by sealant one, sealant two, and the connecting sleeve, thereby reducing the contact amount between powder particles and the weighing body. This reduces the adhesion rate of some fine particles in the powder on the surface or in the gaps of the weighing device, reduces cross-contamination of the powder, and improves the quality of the medicine. The sealing mechanism includes sealant one located above the weighing body, a connecting sleeve connected to the conveying mechanism on the outside of sealant one, sealant two located on the inner top of the connecting sleeve, and a fixing plate connected to the conveying mechanism on the top of the connecting sleeve. Both sealant one and sealant two are conical structures with a diameter that gradually increases towards the weighing body; the connecting sleeve is a trumpet-shaped structure with a diameter that gradually increases towards the weighing body.

[0009] Furthermore, to ensure the medicine bottle is fixed during the filling process, the rotation of the rotating block causes the bidirectional screw to rotate, driving the two sets of clamping plates closer together. This allows the clamping plates to clamp and fix the medicine bottle to the connecting sleeve, preventing the operator from continuously holding the medicine bottle while filling, which could cause the medicine bottle to shake and the powder to fall onto the weighing body through the seal, reducing the filling burden and the powder from flying. The clamping mechanism includes a connecting frame located at the bottom of the fixed plate. The top of the connecting frame has a clamping groove, and both sides of the clamping groove have limit grooves. One set of limit grooves has a bidirectional screw that cooperates with the connecting frame inside, and clamping plates that cooperate with the limit grooves are symmetrically arranged on the outside of the bidirectional screw. A rotating block is provided at one end of the bidirectional screw; the other set of limit grooves has a limit post that penetrates through the clamping plate; the clamping plate is an arc-shaped plate.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model, through the coordinated arrangement of the weighing body, sealing mechanism and clamping mechanism, can not only weigh the medicine powder, but also reduce the contact amount between the medicine powder particles and the weighing body, thereby reducing the adhesion rate of some fine particles in the medicine powder on the surface or gaps of the weighing device, reducing cross-contamination of the medicine powder and improving the quality of medicine.

[0012] 2. Through the sealing mechanism, the double sealing effect of sealing element one and sealing element two ensures that the powder does not directly contact the weighing body during the filling process. When the medicine bottle is filled and weighed, the powder will fly within the sealed space formed by sealing element one, sealing element two and connecting sleeve, thereby reducing the contact amount between the powder particles and the weighing body. This reduces the adhesion rate of some fine particles in the powder on the surface or gaps of the weighing device, reduces cross-contamination of the powder, and improves the quality of the medicine.

[0013] 3. Through the clamping mechanism, the bidirectional screw can be rotated under the action of the rotating block, which drives the two sets of clamping plates to move closer to each other. This allows the clamping plates to clamp and fix the medicine bottle and the connecting sleeve, preventing the operator from continuously holding the medicine bottle to fill it, which would cause the medicine bottle to shake and the medicine powder to fall onto the weighing body through the seal, thus reducing the burden of filling the medicine and the flying of medicine powder.

[0023] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, a weighing device for a powder loading machine is provided.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6 As shown, according to an embodiment of the present invention, a weighing device for a powder loading machine is installed at the bottom of a conveying mechanism 1. The device includes a workbench 2 at the bottom of the conveying mechanism 1, a weighing body 3 at the top of the workbench 2, a sealing mechanism 4 that cooperates with the conveying mechanism 1 above the weighing body 3, and a clamping mechanism 5 on the outside of the sealing mechanism 4.

[0026] By means of the above-mentioned technical solution of this utility model, the present utility model, through the cooperative arrangement of the weighing body 3, the sealing mechanism 4 and the clamping mechanism 5, can not only realize the weighing of medicine powder, but also reduce the contact amount between medicine powder particles and the weighing body 3, thereby reducing the adhesion rate of some fine particles in the medicine powder on the surface or gaps of the weighing device, reducing cross-contamination of medicine powder and improving the quality of medicine.

[0027] In one embodiment, the sealing mechanism 4 includes a first sealing element 401 disposed above the weighing body 3. A connecting sleeve 402, connected to the conveying mechanism 1, is disposed on the outer side of the first sealing element 401. A second sealing element 403 is disposed on the inner top of the connecting sleeve 402. A fixing plate 404, connected to the conveying mechanism 1, is disposed on the top of the connecting sleeve 402. Both the first sealing element 401 and the second sealing element 403 are tapered structures whose diameter gradually increases towards the weighing body 3. The connecting sleeve 402 is tapered towards the weighing body 3. The trumpet-shaped structure with a gradually increasing diameter in the direction of the filling process ensures that the powder does not directly contact the weighing body 3 during the filling process, thanks to the double sealing effect of the first seal 401 and the second seal 403. When the medicine bottle is filled and weighing is carried out, the powder will fly within the sealed space formed by the first seal 401, the second seal 403 and the connecting sleeve 402, thereby reducing the contact amount between the powder particles and the weighing body 3. This reduces the adhesion rate of some fine particles in the powder on the surface or in the gaps of the weighing device, reduces cross-contamination of the powder, and improves the quality of the medicine.

[0028] In addition, it should be noted that the above-mentioned sealing element 401, sealing element 403 and connecting sleeve 402 are all made of rubber, and the middle part of sealing element 401 and sealing element 403 are both extruded and openable structures, which allows the top of the medicine bottle to pass through sealing element 401 and sealing element 403. This is prior art, and will not be elaborated on here.

[0029] In one embodiment, the clamping mechanism 5 includes a connecting frame 501 disposed at the bottom of the fixed plate 404. A clamping groove 502 is provided at the top of the connecting frame 501. Limiting grooves 503 are provided on both sides of the clamping groove 502. A set of limiting grooves 503 contains a bidirectional screw 504 that cooperates with the connecting frame 501. A clamping plate 505 that cooperates with the limiting groove 503 is symmetrically disposed on the outer side of the bidirectional screw 504. A rotating block 506 is provided at one end of the bidirectional screw 504. The other set of limiting grooves 503... The slot 503 has a limiting post 507 that penetrates the clamping plate 505. The clamping plate 505 is an arc-shaped plate. Under the rotation of the rotating block 506, the bidirectional screw 504 rotates, causing the two sets of clamping plates 505 to move closer to each other. This allows the clamping plates 505 to clamp and fix the medicine bottle to the connecting sleeve 402, preventing the operator from continuously holding the medicine bottle to fill it, which would cause the medicine bottle to shake and the medicine powder to fall onto the weighing body 3 through the seal 401, reducing the burden of filling the medicine and the flying of medicine powder.

[0030] In addition, it should be noted that the above-mentioned conveying mechanism 1 consists of a feed pipe, a medicine container, a motor, a conveying pipe, an auger rod, and a discharge pipe. The motor drives the auger rod so that the medicine powder in the medicine container can be conveyed to the discharge pipe through the conveying pipe. The discharge pipe is connected to the connecting sleeve 402 of the sealing mechanism 4. This conveying mechanism 1 is existing technology and will not be elaborated on here.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical application, the operator first weighs the medicine bottle to be filled using the weighing body 3. Then, the operator passes the medicine bottle through the first seal 401 and the second seal 403. The operator then rotates the rotating block 506, causing the bidirectional screw 504 to rotate, which in turn moves the two sets of clamping plates 505 closer together. This clamping plates 505 clamp the medicine bottle to the connecting sleeve 402, preventing the operator from continuously holding the bottle while filling. The conveying mechanism 1 is then activated to transport the powder to the discharge pipe for filling the medicine bottle. After filling, the rotating block 506 is rotated in the opposite direction again. Under the directional rotation of 06, the bidirectional screw 504 rotates, causing the two sets of clamping plates 505 to move away from each other, so that the clamping plates 505 release the medicine bottle and the connecting sleeve 402, and the medicine bottle containing the powder can be taken out from the connecting sleeve 402. During the removal process, the second seal 403 and the first seal 401 seal in sequence. At the same time, under the action of the funnel-shaped structure of the connecting sleeve 402, the powder leaking from the second seal 403 can fall between the connecting sleeve 402 and the second seal 403, preventing the powder from leaking out. Then, the medicine bottle containing the powder is placed on the weighing body 3 for weighing, and the above operation is continued until the required amount of powder is weighed.

[0033] In summary, by utilizing the above-mentioned technical solution of this utility model, through the coordinated arrangement of the weighing body 3, the sealing mechanism 4, and the clamping mechanism 5, not only can the weighing of the medicine powder be achieved, but the contact amount between the medicine powder particles and the weighing body 3 can also be reduced. This reduces the adhesion rate of some fine particles in the medicine powder on the surface or in the gaps of the weighing device, reduces cross-contamination of the medicine powder, and improves the quality of the medicine. Through the sealing mechanism 4, under the double sealing effect of the first sealing element 401 and the second sealing element 403, the medicine powder will not directly contact the weighing body 3 during the filling process. When the medicine bottle is filled and weighing is performed, the medicine powder will be sealed by the first sealing element 401, the second sealing element 403, and the connecting sleeve 40. The powder particles fly within the sealed space formed by the 2, thereby reducing the contact between the powder particles and the weighing body 3. This reduces the adhesion rate of some fine particles in the powder on the surface or in the gaps of the weighing device, reduces cross-contamination of the powder, and improves the quality of the medicine. Through the clamping mechanism 5, the bidirectional screw 504 rotates under the rotation of the rotating block 506, causing the two sets of clamping plates 505 to move closer to each other. This allows the clamping plates 505 to clamp and fix the medicine bottle and the connecting sleeve 402, preventing the operator from continuously holding the medicine bottle to fill it, causing the medicine bottle to shake. This allows the powder to fall onto the weighing body 3 through the seal 401, reducing the burden of filling the medicine and the flying of the powder.
