After the device stops being used, the equipment is comprehensively cleaned and maintained. The remaining chemical agent in the chemical agent tank is cleaned, the chemical agent delivery pipe and the medicine delivery pipe are rinsed to prevent the chemical agent residue from corroding the pipeline. Check the wear conditions of the stirring blade and the scraping disc. If there are severely worn parts, replace them in time.

[0028] Embodiment 1

[0029] Referring to Figures 1 to 5 , for the first embodiment of the present invention, an automatic medicine injection device is provided, and this device includes, A medicine injection mechanism 100, including a medicine tank 110 for carrying medicine; A mixing mechanism 200, including a stirring assembly 210 for stirring the medicine to prevent it from sinking to the bottom, which is arranged in the medicine tank 110; The stirring assembly 210 includes a servo motor 211 adaptively installed outside the medicine tank 110, a connecting rod 212 fixedly connected to the output end of the servo motor 211 through a coupling, and stirring blades 213 circumferentially arrayed at the penetrating end of the connecting rod 212; It should be noted that the servo motor 211 is used to provide rotational power to drive the connecting rod 212 to rotate, and then drive the stirring blades 213 to rotate through the connecting rod 212 to stir the medicine and prevent the medicine from settling to the bottom.

[0030] The transmission assembly 220 for transmitting the rotational power of the stirring assembly 210 is arranged outside the medicine tank 110; The transmission assembly 220 includes a first pulley 221 fixedly sleeved on the outer surface of the connecting rod 212, a synchronous belt 222 sleeved on the outer surface of the first pulley 221, a second pulley 223 sleeved on the inner surface of the other end of the synchronous belt 222, a transmission rod 224 fixedly connected to the inner surface of the second pulley 223, and a ratchet 225 fixedly installed on the outer end face of the transmission rod 224; It should be further noted that the first pulley 221 can rotate synchronously with the connecting rod 212, and through cooperation with the synchronous belt 222, drive the second pulley 223, the transmission rod 224 to rotate and the ratchet 225 to rotate accordingly.

[0031] And a clutch assembly 230 and a cleaning assembly 240 for scraping or stopping scraping the inner wall of the medicine tank 110 according to the rotation direction of the ratchet 225 are arranged inside the medicine tank 110.

[0032] Specifically, the clutch assembly 230 includes a rotating rod 231 fixedly installed on the inner wall of the medicine tank 110 through a bearing, a fixed column 232 fixedly installed at the penetrating end of the rotating rod 231, limiting grooves 233 circumferentially arrayed on the outer surface of the fixed column 232, springs 234 fixedly installed on the inner walls of the limiting grooves 233, and pawls 235 fixedly connected to the other ends of the limiting grooves 233 and used in cooperation with the ratchet 225.

[0033] It needs to be explained that when the ratchet 225 rotates clockwise, the pawl 235 is squeezed into the spring 234, and at this time the cleaning assembly 240 does not work; when the ratchet 225 rotates counterclockwise, the ratchet 225 cooperates with the pawl 235 to drive the fixed column 232, the rotating rod 231 and the reciprocating roller 241 in the cleaning assembly 240 to rotate.

[0034] Furthermore, a bearing sleeve for cooperating with the rotation is installed at the connection between the rotating rod 231 and the medicine tank 110, the ratchet 225 and the pawl 235 are engaged, and the outer surface of the pawl 235 is in sliding contact with the inner wall of the spring 234.

[0035] Among them, when the ratchet 225 rotates clockwise, it can squeeze the pawl 235 into the spring 234; When the ratchet wheel 225 rotates counterclockwise, it can drive the fixed column 232, the rotating rod 231 and the reciprocating roller 241 to rotate through cooperation with the pawl 235.

[0036] Preferably, the cleaning assembly 240 includes a reciprocating roller 241 fixedly sleeved on the outer surface of the rotating rod 231, an inner ball sleeve 242 slidably sleeved on the outer surface of the reciprocating roller 241, a scraping disc 243 fixedly connected to the outer surface of the inner ball sleeve 242, a positioning block 244 fixedly connected to the inner surface of the other end of the scraping disc 243, and a positioning rod 245 fixedly installed on the inner wall of the medicine tank 110 and used in cooperation with the positioning block 244.

[0037] Among them, when the reciprocating roller 241 rotates with the rotating rod 231, it drives the inner ball sleeve 242 to drive the scraping disc 243 to move vertically back and forth along the inner wall of the medicine tank 110, so as to scrape off the medicine attached to the inner wall of the medicine tank 110. Through the cooperation of the positioning block 244 and the positioning rod 245, it can prevent the inner ball sleeve 242 from rotating synchronously with the reciprocating roller 241, ensuring that the scraping disc 243 can move vertically back and forth along the inner wall of the medicine tank 110.

[0038] It should be noted that the outer surface of the scraping disc 243 is in sliding contact with the inner wall of the medicine tank 110, and the positioning block 244 is slidably sleeved on the outer surface of the positioning rod 245.

[0039] Furthermore, the medicine injection mechanism 100 further includes a bracket 120 arranged outside the medicine tank 110, a medicine delivery pipe 130 communicated with the lower part of the medicine tank 110, a metering pump 140 communicated with the other end of the medicine delivery pipe 130, a liquid level gauge 150 communicated with the other end of the metering pump 140, a medicine supply pipe 160 communicated with the other end of the liquid level gauge 150, a control cabinet 170 adaptively installed on the outer surface of the bracket 120, and a medicine adding port 180 opened on the top of the medicine tank 110.

[0040] It should be noted that the medicine delivery pipe 130 is used to deliver the medicine in the medicine tank 110 to the metering pump 140. The metering pump 140 precisely controls the dosing amount of the medicine, and according to the set program or the instruction of the control cabinet 170, it delivers a fixed amount of medicine to ensure the dosing accuracy and meet the strict requirements of different industrial processes for the medicine dosage. The liquid level gauge 150 is used to monitor the liquid level height of the medicine in the medicine tank 110 in real time and feed the data back to the control cabinet 170, so that the operator can understand the medicine surplus and replenish the medicine in time. At the same time, it is also used to control the dosing process to avoid over-dosing or under-dosing of the medicine. The medicine supply pipe 160 is used to deliver the medicine metered by the metering pump 140 to the target position to complete the medicine dosing work. The control cabinet 170 is used to receive the data of the liquid level gauge 150 and control the operation of the metering pump 140 and the rotation of the servo motor 211 according to the preset program, realizing the automatic operation of the whole device. The medicine adding port 180 is used to add medicine into the medicine tank 110 to replenish the medicine reserve.

[0041] Further, the medicine delivery pipe 130, the metering pump 140, the liquid level gauge 150 and the medicine supply pipe 160 are all fixedly installed on the outer surface of the bracket 120; The metering pump 140, the liquid level gauge 150 and the servo motor 211 are all electrically connected to the control cabinet 170.

[0042] Specifically, bearing sleeves for coordinated rotation are installed at the joints between the stirring blades 213 and the medicine tank 110, and the outer end face of the transmission rod 224 is fixedly installed on the top of the medicine tank 110 through a bearing.

[0043] During use, Medicines are added into the medicine tank 110 through the medicine adding port 180 to supplement the medicine reserve. Then, the control cabinet 170 issues an instruction according to a preset program to start the servo motor 211. The servo motor 211 drives the connecting rod 212 to rotate, so that the connecting rod 212 drives the stirring blades 213 to rotate synchronously. Then, the stirring blades 213 stir the medicines in the medicine tank 110 to prevent the medicines from settling to the bottom and ensure uniform mixing of the medicines; Meanwhile: The first pulley 221 rotates synchronously with the connecting rod 212. Through the cooperation between the first pulley 221 and the synchronous belt 222, the second pulley 223, the transmission rod 224 and the ratchet wheel 225 are driven to rotate accordingly; When the ratchet wheel 225 rotates counterclockwise: Through its cooperation with the pawl 235, the pawl 235, the fixed column 232, the rotating rod 231 and the reciprocating roller 241 are driven to rotate synchronously. Then, the reciprocating roller 241 drives the inner ball sleeve 242 to drive the scraping disc 243 to move vertically back and forth along the inner wall of the medicine tank 110, so as to scrape off the medicines attached to the inner wall of the medicine tank 110; When the ratchet wheel 225 rotates clockwise: The pawl 235 is squeezed into the spring 234, and the cleaning assembly 240 stops working; The staff can flexibly control the operating state of the cleaning assembly according to actual needs. For example, at the initial stage of the device operation, when the inner wall of the medicine tank 110 is relatively clean, the rotation direction of the servo motor 211 can be controlled to make the ratchet wheel 225 rotate clockwise, so as to avoid unnecessary operation of the cleaning assembly 240, reduce equipment wear and lower energy consumption; After the medicine filling work lasts for a period of time, adjust the rotation direction of the servo motor 211 to make the ratchet wheel 225 rotate counterclockwise, start the cleaning assembly 240, and timely clean the medicines attached to the inner wall of the medicine tank 110 to prevent the accumulation of medicines from affecting the filling accuracy and the quality of the medicines; Dosing control stage: The liquid level of the chemical agent in the chemical agent tank 110 is monitored in real time by the liquid level gauge 150, and the data is fed back to the control cabinet 170. The control cabinet 170 controls the operation of the metering pump 140 according to the preset program and the data fed back by the liquid level gauge 150. The chemical agent in the chemical agent tank 110 is transported to the medicine delivery pipe 160 through the metering pump 140 via the chemical agent delivery pipe 130. During this process, the dosing amount of the chemical agent is precisely controlled according to the set program or the instruction of the control cabinet 170, and the quantitative chemical agent is transported to, and then the metered chemical agent is transported to the target position through the medicine delivery pipe 160 to complete the dosing work of the chemical agent.

[0044] In summary, through the cooperation of the various components in the mixing mechanism 200, it is not only possible to prevent the chemical agent from precipitating at the bottom of the inner wall of the chemical agent tank 110, but also to select whether to scrape the inner wall of the chemical agent tank 110 by controlling the rotation direction of the servo motor 211, avoiding the chemical agent adhering to the inner side wall of the chemical agent tank 110 and affecting the concentration and dosing accuracy of the chemical agent, so as to achieve the effect of ensuring the accuracy and stability of the chemical agent use while reducing equipment wear.

[0045] Embodiment 2

[0046] Refer to Figures 1 - 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a process method, including an automatic chemical agent dosing device, and its method includes the following steps: S1: First, check whether the chemical agent tank 110, the chemical agent delivery pipe 130 and the medicine delivery pipe 160 are damaged or blocked, ensure that the connections of all pipelines are tight and there is no leakage risk, then check whether the stirring blade 213 and the scraping disc 243 are firmly installed to avoid problems such as loosening and falling off during operation, calibrate the liquid level gauge 150 to ensure the accuracy of its measurement data, so as to accurately monitor the liquid level in the chemical agent tank 110, add an appropriate amount of chemical agent to the chemical agent tank 110 through the chemical agent adding port 180, and observe the change of the value of the liquid level gauge 150 during the adding process to ensure that the added amount of the chemical agent meets the production requirements and avoid overflow caused by excessive addition; S2: Set the stirring time through the control cabinet 170, and set the stirring speed according to the characteristics and process requirements of the chemical agent to ensure that the chemical agent is fully mixed to achieve the best stirring effect and avoid affecting the quality of the chemical agent due to too fast or too slow stirring; S3: Start the servo motor 211 to drive the connecting rod 212 to rotate, and then drive the stirring blade 213 to stir the chemical agent in the chemical agent tank 110. During the stirring process, judge whether the stirring is normal by observing the operation of the stirring blade 213 and the flow state of the chemical agent, and at the same time pay attention to the sound and vibration of the stirring device during operation. If there is any abnormality, stop the machine immediately for inspection; S4: The first pulley 221 rotates synchronously with the connecting rod 212, drives the second pulley 223, the transmission rod 224 and the ratchet 225 to rotate through the synchronous belt 222. If the inner wall of the medicine tank 110 is relatively clean at this time, control the servo motor 211 to rotate the ratchet 225 clockwise, so that the cleaning assembly 240 is in a stopped working state, reducing unnecessary wear and energy consumption of the equipment; S5: When the medicine is stirred evenly, the control cabinet 170 controls the metering pump 140 to start according to the preset program and the data fed back by the liquid level gauge 150. The metering pump 140 conveys the medicine in the medicine tank 110 to the medicine delivery pipe 160 through the medicine delivery pipe 130 according to the set dosing amount, and then the medicine delivery pipe 160 conveys the medicine to the target position to complete the dosing work of the medicine; S6: During the dosing process of the medicine, the liquid level gauge 150 monitors the liquid level height of the medicine in the medicine tank 110 in real time and continuously feeds back the data to the control cabinet 170. If the liquid level is close to the preset minimum liquid level value, the control cabinet 170 issues an alarm to remind the staff to replenish the medicine in time to prevent the production from being affected due to insufficient medicine. At the same time, the control cabinet 170 can automatically adjust the working state of the metering pump 140 according to the liquid level change situation to ensure the stability and accuracy of the dosing process.

[0047] S7: After the dosing work of the medicine lasts for a period of time, the staff judges that there may be medicine adhering and accumulating on the inner wall of the medicine tank 110. At this time, adjust the rotation direction of the servo motor 211 to drive the ratchet 225 to rotate counterclockwise. Through the cooperation of the ratchet 225 and the pawl 235, drive the fixed column 232, the rotating rod 231 and the reciprocating roller 241 to rotate, and then drive the inner ball sleeve 242 to drive the scraping disc 243 to move vertically back and forth along the inner wall of the medicine tank 110 to scrape off the medicine adhering to the tank wall.

[0048] S8: After completing a cleaning work, you can choose to continue cleaning or stop according to the actual situation.

If the liquid level is close to the preset minimum liquid level value, the control cabinet (170) will issue an alarm to remind the staff to replenish the medicament in time to prevent the production from being affected due to insufficient medicament. At the same time, the control cabinet (170) can automatically adjust the working state of the metering pump (140) according to the liquid level change situation to ensure the stability and accuracy of the filling process; S7: After the filling work of the medicament lasts for a period of time, the staff judges that there may be medicament adhesion and accumulation on the inner wall of the medicament tank (110). At this time, adjust the rotation direction of the servo motor (211) to drive the ratchet (225) to rotate counterclockwise. Through the cooperation of the ratchet (225) and the pawl (235), drive the fixed column (232), the rotating rod (231) and the reciprocating roller (241) to rotate, and then the inner ball sleeve (242) drives the scraping disc (243) to move vertically back and forth along the inner wall of the medicament tank (110) to scrape off the medicament attached to the tank wall; S8: After completing one scraping operation, continue scraping or stop according to the actual situation. After the device stops being used, conduct a comprehensive cleaning and maintenance of the equipment, clean the remaining medicament in the medicament tank (110), rinse the medicament delivery pipe (130) and the medicine delivery pipe (160) to prevent the remaining medicament from corroding the pipes, check the wear conditions of the stirring blades (213) and the scraping discs (243), replace the severely worn components in a timely manner, maintain equipment such as the servo motor (211) and the metering pump (140), add lubricating oil, and check whether the electrical connections are loose to ensure that the equipment can operate normally during the next use.
