Description

Technical Field

[0001] The invention relates to the technical field of subpackaging devices, in particular to a calcium folinate subpackaging precision metering device. Background Art

[0002] Calcium folinate is a synthetic water-soluble folic acid derivative with stronger water solubility and biological activity. As an important pharmaceutical compound, calcium folinate is mainly used to antagonize the toxic effects of folic acid antagonists (such as methotrexate, pyrimethamine, etc.). By supplementing exogenous folic acid coenzyme, it restores the transfer function of one-carbon units in nucleotide synthesis and reverses the DNA synthesis disorder caused by folic acid deficiency. It is widely used in clinical practice to rescue bone marrow suppression after tumor chemotherapy, treat megaloblastic anemia, and prevent and treat diseases related to folic acid deficiency. It has a clear mechanism of action and high safety. It is a key drug for regulating the folic acid metabolic pathway and has irreplaceable clinical value in the treatment of hematological diseases and adjuvant anti-tumor therapy.

[0003] The existing technology often uses piston-type metering equipment for metering and packaging. The piston-type metering equipment achieves metering through the reciprocating motion of the piston in the cylinder. The fluid pushes the piston back and forth in the sealed cavity. Each time the piston completes a stroke, it sucks in a certain volume of fluid from the inlet and discharges it from the outlet. The fixed relationship between the displacement of the piston and the volume of the sealed cavity is used to convert the fluid volume into the number of piston movements and the stroke amount. The piston movement is then transmitted to the display device through a transmission mechanism such as gears, thereby cumulatively displaying the total amount of the measured fluid.

[0004] Although the piston metering equipment used in the existing technology can achieve basic quantitative packaging, it has common defects. During discharge, due to the horizontal design of the one-way valve at the discharge port, some raw materials will still remain on the plate of the one-way valve after discharge. To this end, a common solution is to design the horizontally set plate into a cone shape, and the residual raw materials fall through the inclined design of the cone. However, the inclined plate has a poor discharge effect for some raw materials with adsorptive properties, or manual methods are used to clean the residual materials. However, manual intervention must mean stopping the machine for cleaning, which in turn leads to reduced packaging efficiency.

[0005] Therefore, we proposed a precise metering device for calcium folinate subpackaging. Summary of the Invention

[0019] The present invention has the following beneficial effects:

[0020] 1. In the calcium folinate packaging precision metering device, the shaking component is driven by the driving component. The shaking rod drives the shaking cam to periodically hit the bottom surface of the sealing plate. The conical surface design allows the residual material to slide down due to vibration and gravity. This design allows the striking process to be carried out during both suction and discharge, thereby ensuring that the residue on the surface of the sealing plate is removed during each suction. The shaking during discharge can help the raw materials quickly leave the surface of the discharge sealing plate, fundamentally avoiding the accumulation of errors during multi-batch packaging. The shaking corrugated sealing plate seals the shaking trough to prevent the material from entering the mechanical structure and causing jamming.

[0021] 2. This calcium folinate dispensing and precision metering device utilizes an adsorption fixture assembly and hydraulic components. When the drive gear rotates with the piston plate, the meshing hydraulic rack drives the hydraulic plate to slide within the hydraulic oil reservoir. This hydraulic oil is squeezed into the piston reservoir through a connecting channel, pushing the adsorption drive piston plate downward. Through the rack and pinion transmission component, the active drive rack drives the driven drive rack upward, allowing the adsorption sealing plate to closely contact the top surface of the discharge sealing plate, creating a stable adsorption force. This design offsets the vibration of the shaking assembly during the suction phase, ensuring a tight seal between the discharge base and the discharge sealing plate, preventing material leakage or premature discharge.

[0022] 3. This calcium folinate dispensing and precision metering device uses a cleaning assembly to pulse-clean the sidewalls of the discharge sealing plate. When the sealing plate resets and moves upward, the extrusion rod drives the extrusion ring to compress the annular airbag, storing gas energy. Under normal conditions, the cross-sealing plate, driven by the reset spring, blocks the cleaning channel to prevent air leakage. When the discharge sealing plate moves to a specific position, the resistance plate pushes the cross-sealing plate upward, connecting the vent hole with the cleaning channel. The gas accumulated in the airbag is instantly ejected at high speed, forming a directional airflow to flush the calcium foliate powder remaining on the sidewalls of the discharge sealing plate. This design significantly improves cleaning efficiency compared to traditional continuous airflow and is particularly suitable for highly absorptive powder materials.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1: This example aims to solve the problem of residual raw materials at the discharge port affecting the measurement and packaging accuracy. Figures 1 to 9 A calcium folinate subpackaging precision metering device includes a subpackaging metering device 1.

[0035] The subpackaging and metering equipment 1 is used to measure and subpack the calcium folinate raw material. The subpackaging and metering equipment 1 includes a conveyor belt 11 and a subpackaging box 12 for subpackaging, as well as a three-way pipe 13 for metering, a piston cylinder 14, a subpackaging and metering piston plate 15, an inlet one-way valve 16 and a discharge one-way component 17. The discharge one-way component 17 includes a discharge base 171, a discharge sealing plate 172 and a discharge sealing spring 173. A shaking component 2 is installed in the three-way pipe 13.

[0036] A packaging box 12 is provided on the conveyor belt 11 , a tee pipe 13 is located above the conveyor belt 11 , and a piston cylinder 14 , a packaging metering piston plate 15 , an inlet one-way valve 16 and a discharge one-way assembly 17 are installed in the tee pipe 13 .

[0037] Most of the structures of the packaging and metering equipment 1 of this scheme are existing technologies. The packaging and metering piston plate 15 is driven by the piston cylinder 14 to perform piston movement in the three-way pipe 13. When the piston cylinder 14 slides to the left, the discharge one-way component 17 is closed and the feed one-way valve 16 is opened. The suction operation is performed through the feed one-way valve 16. The specific amount of raw materials obtained is controlled by the sliding distance of the packaging and metering piston plate 15. When the packaging and metering piston plate 15 slides to the right, the discharge one-way component 17 is opened and the feed one-way valve 16 is closed. At this time, the raw materials sucked into the three-way pipe 13 are discharged through the opened discharge one-way component 17 and enter the packaging box 12. The assembled packaging box 12 is transported to the next process under the movement of the conveyor belt 11. The structure and working principle shown above are existing technologies and will not be elaborated on.

[0038] Specifically, for the feed one-way valve 16 and the discharge one-way component 17, in order to ensure the accuracy of calcium folinate suction and discharge, the horizontal plates of the feed one-way valve 16 and the discharge one-way component 17 are made into inclined cone shapes. This design can prevent the raw materials from remaining on the horizontal plates, which in turn leads to large errors in the raw materials after packaging.

[0039] The material shaking assembly 2 is used to strike the residual material remaining on the surface of the discharge sealing plate 172 . The material shaking assembly 2 includes a material shaking rod 22 , a material shaking shaft 24 , a material shaking torsion spring 25 and a striking cam 26 .

[0040] The shaking material assembly 2 includes a shaking material groove 21 opened on the inner wall of the three-way pipe 13, and a shaking material shaft 24 is fixedly connected to the shaking material groove 21. The side wall of the shaking material shaft 24 is rotatably connected to the shaking material rod 22 through the shaking material torsion spring 25. The side wall of the shaking material rod 22 is fixedly connected to the shaking material corrugated sealing plate 23, and the other side of the shaking material corrugated sealing plate 23 is installed on the inner wall of the shaking material groove 21.

[0041] A striking cam 26 is provided on one side of the shaking rod 22 , and the center of the striking cam 26 is rotatably connected to a cam shaft 27 through a cam torsion spring 28 . The cam shaft 27 is fixedly connected to the shaking groove 21 , and a No. 1 rope 29 is provided on the side wall of the cam shaft 27 .

[0042] The rotation of the striking cam 26 is driven by the driving assembly 3, which includes a driving box 31 installed on the outer wall of the tee pipe 13. A driving fixed shaft 33 is fixedly connected to the driving box 31. The side wall of the driving fixed shaft 33 is rotatably connected to a driving gear 34 through a driving torsion spring 35. A No. 2 rope 32 is provided on the outer side of the driving gear 34. The other end of the No. 2 rope 32 is fixedly connected to one side of the filling and metering piston plate 15. A No. 1 rope 29 is provided on the inner side of the driving gear 34.

[0043] The shaking assembly 2 is designed to shake off the raw materials remaining on the surface of the discharge sealing plate 172. The shaking rod 22 hits the bottom of the discharge sealing plate 172, thereby driving the discharge sealing plate 172 to shake. Due to its conical design, the raw materials remaining on the surface of the discharge sealing plate 172 are easier to fall off.

[0044] When the packing and metering piston plate 15 moves to the left to absorb material, the driving gear 34 is synchronously pulled to rotate by the No. 2 rope 32. At the same time, through the connection of the No. 1 rope 29, the striking cam 26 is driven to rotate. At this time, the shaking rod 22 swings due to the rotation of the striking cam 26, and then strikes the bottom surface of the discharge sealing plate 172 multiple times, shaking off the residual material remaining on the surface of the discharge sealing plate 172; when the packing and metering piston plate 15 moves to the right to discharge material, the driving gear 34 is reset under the pulling force of the packing and metering piston plate 15, and the striking cam 26 rotates synchronously, thereby driving the shaking rod 22 again to complete multiple striking cycles.

[0045] This design allows the striking process to be carried out during both suction and discharge, thereby ensuring that residues on the surface of the discharge sealing plate 172 are cleared each time the material is sucked. The shaking during discharge can help the raw materials quickly leave the surface of the discharge sealing plate 172, fundamentally avoiding the accumulation of errors during multi-batch packaging. At the same time, in order to ensure the accuracy of the falling of residual raw materials, the conveyor belt 11 stops running while the device is sucking and discharging materials, and the conveyor belt 11 moves after the suction is completed. At this time, the movement of the piston cylinder 14 is stopped to give the conveyor belt 11 time to transport the packaging box 12. When the next packaging box 12 runs to the bottom of the three-way pipe 13, the piston cylinder 14 is started again.

[0046] The setting of the shaking material corrugated sealing plate 23 enables a sealed connection between the shaking material rod 22 and the shaking material trough 21, forming a flexible sealing structure, which can effectively block the calcium folinate powder from entering the shaking material trough 21, prevent the mechanism from being stuck due to material accumulation, and at the same time allow the shaking material rod 22 to swing freely within a preset angle range, ensuring the reliability of the striking action.

[0047] Example 2: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 9 An adsorption and fixing component 4 is provided in the discharging base 171. The adsorption and fixing component 4 includes an adsorption channel 41 and a piston chamber 44 opened in the discharging base 171. A gear rack transmission component 42 and an adsorption sealing plate 43 are installed in the adsorption channel 41. The gear rack transmission component 42 includes a transmission gear 421 rotatably connected to the adsorption channel 41. The side wall of the transmission gear 421 is meshed with an active transmission rack 422 and a driven transmission rack 423.

[0048] The bottom of the driven transmission rack 423 is fixedly connected to the adsorption sealing plate 43 , and the top of the active transmission rack 422 is fixedly connected to the adsorption driving piston plate 45 , which is slidably connected in the piston chamber 44 .

[0049] The sliding of the adsorption drive piston plate 45 in the piston chamber 44 is realized by the hydraulic component 5. The hydraulic component 5 includes a hydraulic oil tank 51 and a connecting channel 53 opened in the discharge base 171. A hydraulic plate 52 is slidably connected in the hydraulic oil tank 51. A hydraulic rack 54 is fixedly connected to one side of the hydraulic plate 52. The hydraulic rack 54 is meshed with the drive gear 34. The hydraulic oil tank 51 and the piston chamber 44 are connected through the connecting channel 53.

[0050] The adsorption fixing component 4 realizes dynamic sealing of the discharge sealing plate 172 through hydraulic transmission. When the driving gear 34 is rotated in conjunction with the filling and metering piston plate 15, the hydraulic rack 54 engaged therewith drives the hydraulic plate 52 to slide in the hydraulic oil tank 51, and squeezes the hydraulic oil into the piston tank 44 through the connecting channel 53, pushing the adsorption drive piston plate 45 to move downward. The linear motion is converted into an upward displacement of the adsorption sealing plate 43 through the gear rack transmission component 42 (the transmission gear 421 meshes with the active transmission rack 422 and the driven transmission rack 423), so that it fits tightly against the top surface of the discharge sealing plate 172. Through this design, a stable adsorption force can be formed in the suction stage, offsetting the vibration effect of the shaking component 2 when hitting, ensuring the sealing between the discharge sealing plate 172 and the discharge base 171, avoiding material leakage or premature discharge due to sealing failure, and ensuring the accuracy of material inventory during the metering process from the mechanical structure level.

[0051] Example 3: This example is an explanation based on Example 2. For details, please refer to Figures 1 to 9A cleaning assembly 6 is provided on the inner wall of the tee pipe 13, and the cleaning assembly 6 is used to clean the side wall of the discharge sealing plate 172. The cleaning assembly 6 includes a mounting ring 61 fixedly connected to the inner wall of the tee pipe 13, and an annular airbag 62 and an extrusion ring 63 are installed in the mounting ring 61. The bottom of the extrusion ring 63 is fixedly connected to an extrusion rod 64, and the other end of the extrusion rod 64 is fixedly connected to the top of the discharge sealing plate 172.

[0052] The inner wall of the mounting ring 61 is provided with a cleaning channel 65, a blocking groove 66 and a cross groove 611. The cleaning channel 65 is communicated with the annular airbag 62. A cross blocking plate 67 is inserted in the blocking groove 66. The bottom of the cross blocking plate 67 is slidably connected in the cross groove 611. The cross blocking plate 67 and the cross groove 611 are connected by a reset spring 610. A vent 68 is provided on the side wall of the cross blocking plate 67. A resistance plate 69 is provided at the bottom of the cross blocking plate 67. The resistance plate 69 is fixedly connected to the side wall of the extrusion rod 64.

[0053] The cleaning component 6 realizes precise cleaning of the side wall of the discharge sealing plate 172 by constructing a pulse cleaning system synchronized with the sealing reset process. When the discharge sealing plate 172 slides upward during the reset process, the extrusion ring 63 is driven by the extrusion rod 64 to compress the annular airbag 62, so that the gas stored in the annular airbag 62 is ejected at high speed through the cleaning channel 65 toward the side wall of the discharge sealing plate 172, forming a directional airflow to flush the attached calcium folinate powder. This design utilizes the mechanical movement of the discharge sealing plate 172 reset to convert it into pneumatic energy, avoiding the complexity of traditional cleaning methods that rely on external air sources.

[0054] At the same time, the cooperation between the cross-sealing plate 67 and the resistance plate 69 constructs an airflow control mechanism of "sealing-instantaneous conduction", which significantly improves the cleaning efficiency. When the discharge sealing plate 172 is not reset, the cross-sealing plate 67 relies on gravity to tightly fit the sealing slide 66, blocking the connection between the cleaning channel 65 and the outside world, so that the annular airbag 62 is in an expanded state, ensuring the effective storage of compressed gas; when the discharge sealing plate 172 is reset upward to a fixed position, the resistance plate 69 pushes the cross-sealing plate 67 to move upward, and the air vent 68 is aligned with the cleaning channel 65. The gas accumulated in the annular airbag 62 is released instantly, forming a high-speed airflow to impact-clean the discharge sealing plate 172. Compared with traditional continuous airflow cleaning, it can improve the removal rate of residual powder on the wall, which is especially suitable for powder materials with small particle size and strong adsorption such as calcium folinate. It eliminates the risk of sealing failure caused by residue from the structural design level, and provides a guarantee for the reliable sealing of the subsequent adsorption and fixing component 4.

[0055] In order to ensure that the discharge sealing plate 172 has sufficient force when it is reset and overcome the elasticity of the annular airbag 62, a rope can be set between the discharge sealing plate 172 and the packaging and metering piston plate 15, so that the reset process of the discharge sealing plate 172 adds the direct pulling force of the piston cylinder 14 on the basis of the reset spring 610, thereby overcoming the elastic force of the annular airbag 62. The method of overcoming the elastic force of the annular airbag 62 can be replaced according to actual needs.

[0056] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0057] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
