Description

Technical Field

[0001] The utility model relates to the technical field of chemical drug quantitative measurement, in particular to a chemical drug preparation quantitative measurement mechanism. Background Art

[0002] During the production and processing of chemical preparations, it is often necessary to add corresponding chemical raw materials to the chemicals in a quantitative manner, so when adding chemicals, it is often necessary to use corresponding quantitative mechanisms for quantitative addition.

[0003] Existing quantitative addition mechanisms often introduce chemical agents into a quantitative cylinder, then open the valve of the quantitative cylinder to guide the agents out for addition. During the addition process, the quantitative amount is observed by the scale lines on the quantitative cylinder. However, the quantitative amount is inaccurate when the scale is observed by the naked eye, and there is an error in the amount of addition, which affects the production effect of chemical drugs. Therefore, we propose a quantitative mechanism for chemical drug preparations. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical drug preparation quantitative mechanism, comprising a carrier plate, a support block is fixed on one side of the top of the carrier plate and a storage barrel is fixed on the top of the support block, a quantitative cylinder is fixed on the other side of the top of the carrier plate, a liquid pump is fixed at the middle of the top of the carrier plate, one end of the liquid pump is connected to the lower side of one side wall of the storage barrel through a first conduit, and the other end of the liquid pump is connected to the top of the quantitative cylinder through a second conduit, and a controller is fixed on the top of the carrier plate;

[0006] A quantitative component is passed through the top of the quantitative cylinder, and the quantitative component includes a square tube. The square tube is fixedly passed through the quantitative cylinder, and a movable column is inserted into the inner cavity of the square tube. A floating ball is arranged at the tail end of the movable column. A sliding groove is opened at the tail end of the movable column, and an adaptive movable block is arranged in the inner cavity of the sliding groove. A pressure sensor is fixed on the top of the inner cavity of the sliding groove, and the bottom of the movable block is passed through the connecting block to pass through the tail end of the movable column and is fixedly connected to the floating ball.

[0007] By adopting the above technical solution, the liquid pump is first started to extract the medicine liquid in the storage barrel and introduce it into the inner cavity of the metering cylinder. Then, as the liquid level in the metering cylinder rises, the float will rise, and the float will drive the movable block to rise and put pressure on the pressure sensor. Therefore, the controller will stop the liquid pump to transport the medicine liquid into the metering cylinder, thereby achieving accurate quantification of the medicine liquid.

[0008] As a preferred embodiment of the present utility model, a servo motor is fixed to the top of the inner cavity of the square tube, a partition is fixed to the upper side of the inner cavity of the square tube, the transmission shaft of the servo motor movably penetrates through the partition and is fixedly connected with a screw rod, a threaded hole is formed at the top of the movable column, the screw rod is inserted into the threaded hole and is in threaded engagement therewith, and a distance sensor is fixed to one side of the top of the movable column.

[0009] By adopting the above technical solution, the signal output end of the distance sensor is connected to the signal input end of the controller, and the signal output end of the controller is connected to the signal input end of the servo motor. Thus, when different amounts of liquid medicine need to be quantified, the servo motor is started to drive the screw rod to rotate, so as to drive the movable column to lift by using the thread drive. During the lifting process, the distance sensor will feedback the adjusted distance value to the controller, so as to adjust the position of the floating ball, and further adjust the quantified amount of the liquid medicine, further improving the adaptability of the device during use.

[0010] As a preferred embodiment of the present utility model, the tail end of the second conduit penetrates through the top of the metering cylinder and is fixedly connected with an inclined tube.

[0011] By adopting the above technical solution, when the liquid medicine is introduced into the metering cylinder, the liquid medicine can be guided to the inner wall of the metering cylinder, thus avoiding the splashing caused by the impact of the liquid medicine on the bottom of the inner cavity of the metering cylinder and impacting the floating ball, and further avoiding the shaking of the floating ball and the unstable liquid level affecting the metering effect.

[0012] As a preferred embodiment of the present utility model, the tail end of the metering cylinder is fixedly communicated with a conduit, and the conduit penetrates through the carrier plate and is fixedly communicated with an electromagnetic valve.

[0013] By adopting the above technical solution, after the metering is completed, opening the electromagnetic valve can export the metered liquid medicine.

[0014] As a preferred embodiment of the present utility model, an end cover is threadedly connected to the top opening of the storage barrel.

[0015] By adopting the above technical solution, the setting of the end cover makes it convenient to open and supplement the liquid medicine into the storage barrel.

[0016] As a preferred embodiment of the present utility model, mounting holes are formed at the four corners of the top of the carrier plate.

[0018] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] A chemical drug preparation quantitative mechanism of the technical solution of the present application pumps liquid medicine into a quantitative cylinder through a liquid pump. Then, as the liquid level rises, the floating ball will be lifted by the liquid level, thereby driving the movable block to press on the pressure sensor. As a result, the controller will stop the liquid pump from delivering the liquid medicine, and then open the solenoid valve to discharge the quantitatively measured liquid medicine, thus achieving accurate quantification and improving the effect of quantitative addition;

[0020] The screw rod is driven to rotate by a servo motor, and the movable column is driven to lift by using the thread drive. During the lifting process, the distance sensor will feedback the adjusted distance value to the controller, thereby adjusting the position of the floating ball, and further adjusting the quantity of the liquid medicine quantification, which further improves the adaptability of the device during use.

[0029] Please refer to Figures 1-3, the present utility model provides a technical solution: a quantitative mechanism for chemical pharmaceutical preparations, including a carrier plate 1. On one side of the top of the carrier plate 1, a support block is fixed, and a storage barrel 11 is fixed on the top of the support block. On the other side of the top of the carrier plate 1, a quantitative cylinder 2 is fixed. In the middle of the top of the carrier plate 1, a liquid pump 12 is fixed. One end of the liquid pump 12 is communicated with the lower side of one side wall of the storage barrel 11 through a first conduit 13, and the other end of the liquid pump 12 is communicated with the top of the quantitative cylinder 2 through a second conduit 14. A controller 15 is fixed on the top of the carrier plate 1;

[0030] A quantitative assembly 3 penetrates through the top of the quantitative cylinder 2. The quantitative assembly 3 includes a square tube 31 which is fixedly penetrated through the quantitative cylinder 2. An activity column 32 is inserted into the inner cavity of the square tube 31. A floating ball 36 is arranged at the tail end of the activity column 32. A sliding groove is opened at the tail end of the activity column 32. An adapted activity block 37 is arranged in the inner cavity of the sliding groove. A pressure sensor 38 is fixed at the top of the inner cavity of the sliding groove. The bottom of the activity block 37 is fixedly connected with the floating ball 36 through a connecting block penetrating through the tail end of the activity column 32;

[0031] It should be noted that the signal output end of the pressure sensor 38 is connected to the signal input end of the controller 15. The controller 15 is a PLC controller. The signal output end of the controller 15 is connected to the signal input end of the liquid pump 12;

[0032] During actual use, first start the liquid pump 12 to extract the liquid medicine in the storage barrel 11 and introduce it into the inner cavity of the quantitative cylinder 2. Then, as the liquid level in the quantitative cylinder 2 rises, the floating ball 36 will be lifted. The floating ball 36 will drive the activity block 37 to rise and exert pressure on the pressure sensor 38. Thus, the controller 15 will stop the liquid pump 12 from delivering the liquid medicine into the quantitative cylinder 2, thereby realizing accurate quantification of the liquid medicine.

[0033] Furthermore, the tail end of the quantitative cylinder 2 is fixedly communicated with a conduit 21. The conduit 21 penetrates through the carrier plate 1 and is fixedly communicated with an electromagnetic valve 22. After quantification, opening the electromagnetic valve 22 can export the quantified liquid medicine.

[0034] Even further, mounting holes 16 are opened at the four corners of the top of the carrier plate 1. The setting of the mounting holes 16 makes it convenient to install and fix the whole device.

[0035] It is worth introducing that the top opening of the storage barrel 11 is threadedly connected with an end cover. The setting of the end cover makes it convenient to open and supplement the liquid medicine into the storage barrel 11.

[0036] It should be noted that the tail end of the second conduit 14 penetrates through the top of the quantitative cylinder 2 and is fixedly connected with an inclined tube 17. Thus, when introducing the liquid medicine into the quantitative cylinder 2, the liquid medicine can be guided to the inner wall of the quantitative cylinder 2, thereby avoiding the liquid medicine splashing on the bottom of the inner cavity of the quantitative cylinder 2 and impacting the floating ball 36, and further avoiding the floating ball 36 shaking and the liquid level being unstable, which affects the quantification effect.

[0037] As Figure 1 and 3 shown; a servo motor 33 is fixed to the top of the inner cavity of the square pipe 31, a partition plate 34 is fixed to the upper side of the inner cavity of the square pipe 31, the transmission shaft of the servo motor 33 movably penetrates through the partition plate 34 and is fixedly connected with a screw rod 35, a threaded hole is opened at the top of the movable column 32, the screw rod 35 is inserted into the threaded hole and is in threaded engagement, and a distance sensor 39 is fixed to one side of the top of the movable column 32;

[0038] The signal output end of the distance sensor 39 is connected to the signal input end of the controller 15, and the signal output end of the controller 15 is connected to the signal input end of the servo motor 33. Thus, when different amounts of liquid medicine need to be quantitatively measured, the servo motor 33 is started to drive the screw rod 35 to rotate, so as to drive the movable column 32 to lift by using thread drive. During the lifting process, the distance sensor 39 will feedback the adjusted distance value to the controller 15, so as to adjust the position of the floating ball 36, and further adjust the quantitatively measured amount of the liquid medicine, further improving the adaptability of the device during use.

[0039] The implementation principle of a quantitative mechanism for a chemical pharmaceutical preparation in this application is as follows: during actual use, first, the servo motor 33 is started to drive the screw rod 35 to rotate, so as to drive the movable column 32 to lift by using thread drive. During the lifting process, the distance sensor 39 will feedback the adjusted distance value to the controller 15, so as to adjust the position of the floating ball 36, and further adjust the quantitatively measured amount of the liquid medicine. Then, the liquid pump 12 is started to extract the liquid medicine in the storage barrel 11 and introduce it into the inner cavity of the quantitative cylinder 2. Then, as the liquid level in the quantitative cylinder 2 rises, the floating ball 36 will be lifted, and the floating ball 36 will drive the movable block 37 to lift and press the pressure sensor 38, so that the controller 15 will stop the liquid pump 12 from delivering the liquid medicine into the quantitative cylinder 2, thus realizing accurate quantitative measurement of the liquid medicine. After the quantitative measurement is completed, opening the electromagnetic valve 22 can export the quantitatively measured liquid medicine.

[0040] In addition, all components included in a quantitative mechanism for a chemical pharmaceutical preparation of the present utility model are common standard components or components known to those skilled in the art, and their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
