Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing machines, in particular to a medicine film manufacturing machine. Background Art

[0002] The pesticide test tube medicine film technology is an innovative pesticide application technology. It mainly wraps the pesticide active ingredients inside through special materials to form a film-like structure. This medicine film has super wetting, spreading, penetrating and adhering abilities, which can improve the effective utilization rate of pesticides. In the existing medicine film production process, since most of the manufacturing machines are used for one-way assembly, the coating of the liquid medicine on the medicine film may be uneven, affecting the quality and effect of the medicine film. Therefore, we propose a medicine film manufacturing machine to solve the problems mentioned above. Summary of the Utility Model

[0003] In order to overcome the problem that in the existing medicine film production process, since most of the manufacturing machines are used for one-way assembly, the coating of the liquid medicine on the medicine film may be uneven, affecting the quality and effect of the medicine film.

[0004] The technical solution of the utility model is as follows: A medicine film manufacturing machine includes a support assembly, a conveying assembly, a limiting assembly, a coating chamber and a heating chamber; at the upper end of the support assembly, there is installed a conveying assembly for unwinding and winding the raw material film. On both sides of the middle part of the conveying assembly, three groups of limiting assemblies are symmetrically installed for correcting possible offsets of the raw material film during transportation. Above the conveying assembly, there is a coating chamber for evenly spraying the liquid medicine and its lower end is fixedly connected to the support assembly. On one side of the coating chamber, there is a heating chamber for heating the coated medicine film and its lower end is fixedly connected to the support assembly.

[0005] Preferably, when making a medicine film, first, driven by the first motor, the first rotating shaft rotates along the first vertical plate, driving the unwinding of the raw material film body. Then, driven by the second motor, the second rotating shaft rotates along the second vertical plate, driving the winding of the raw material film body. Thus, the raw material film body can smoothly and continuously proceed to the next process. According to the width of the raw material film body, through the adjustment of the plug, the telescopic rod moves horizontally along the rectangular telescopic sleeve to a suitable width, and then the plug passes through the rectangular telescopic sleeve and is positioned and connected to the telescopic rod through the positioning hole. Then, the liquid medicine is poured into the liquid supply tank through the liquid inlet pipe. Then, driven by the water pump, the liquid medicine enters the connecting pipe from the liquid supply tank and is sprayed onto the raw material film body through the liquid outlet pipe to form the required medicine film. Finally, driven by the second cylinder, the telescopic column drives the rectangular telescopic sleeve to move downward along the circular telescopic sleeve to a suitable height. Thus, after the liquid medicine is sprayed, it is evenly leveled to avoid uneven spraying, which affects the quality and effect of the medicine film. At the same time, during the production of the medicine film, the support column plays a role in firmly supporting the operating platform.

[0006] Preferably, the support assembly includes an operating table and support columns. Multiple groups of support columns for stably supporting the operating table are installed at both side edges of the lower end of the operating table. During the production process of the medicine film, the support columns play a role in stably supporting the operating table, improving the stability of the production machine.

[0007] Preferably, the conveying assembly includes a first vertical plate, a first motor, a first rotating shaft, a raw material film body, a second vertical plate, a second motor, and a second rotating shaft. The first vertical plates fixedly connected to the operating table at the lower ends are sleeved outside both ends of the first rotating shaft. The first motors are installed at both ends of the first rotating shaft. A second rotating shaft is provided on one side of the first rotating shaft. The second vertical plates fixedly connected to the operating table at the lower ends are sleeved outside both ends of the second rotating shaft. The second motors are installed at both ends of the second rotating shaft. A raw material film body is provided between the first rotating shaft and the second rotating shaft. The raw material film body is connected to the first rotating shaft for unwinding, and the raw material film body is connected to the second rotating shaft for winding. When the medicine film needs to be produced, first, driven by the first motor, the first rotating shaft rotates along the first vertical plate, driving the raw material film body to unwind. Then, driven by the second motor, the second rotating shaft rotates along the second vertical plate, driving the raw material film body to wind. Thus, the raw material film body can smoothly and continuously proceed to the next process.

[0008] Preferably, the limiting assembly includes an L-shaped telescopic sleeve, a first cylinder, a telescopic plate, a convex limiting plate, and a rectangular soft pad. The first cylinder is installed on one side of the L-shaped telescopic sleeve. The telescopic plate is sleeved inside the L-shaped telescopic sleeve. The convex limiting plate is installed at the lower end of the telescopic plate away from the L-shaped telescopic sleeve. The rectangular soft pad is installed on the side of the convex limiting plate close to the raw material film body. According to the width of the raw material film body, driven by the first cylinder, the telescopic plate drives the convex limiting plate to move horizontally along the L-shaped telescopic sleeve to approach the raw material film body until the rectangular soft pad fits the raw material film body, limiting it and preventing the raw material film body from shifting during transportation, ensuring that the raw material film body can be accurately aligned and positioned. The rectangular soft pad can avoid abrasion of the raw material film body.

[0009] Preferably, a liquid supply tank is installed at the upper end of the coating chamber. An inlet pipe is installed at the upper corner of the liquid supply tank. A water pump is installed at one corner of the liquid supply tank. Connecting pipes passing through the coating chamber are installed on both sides of the liquid supply tank. An outlet pipe is installed between the ends of the two connecting pipes away from the liquid supply tank. According to the width of the raw material film body, through the adjustment of the bolt, the telescopic rod moves horizontally along the rectangular telescopic sleeve to an appropriate width, and then the bolt passes through the rectangular telescopic sleeve and is connected to the telescopic rod through the positioning hole. Then, the liquid medicine is poured into the liquid supply tank through the inlet pipe. Then, driven by the water pump, the liquid medicine enters the connecting pipes from the liquid supply tank and is sprayed onto the raw material film body through the outlet pipe to form the required medicine film.

[0010] Preferably, a circular telescopic sleeve fixedly connected to the coating bin is provided on the side of the liquid supply tank where the water pump is installed. A second cylinder is installed at the upper end of the circular telescopic sleeve. A telescopic column is sleeved inside the circular telescopic sleeve. A rectangular telescopic sleeve is installed at the lower end of the telescopic column. Each of the two ends of the rectangular telescopic sleeve is sleeved with a telescopic rod. A pin is provided at the connection between the rectangular telescopic sleeve and the telescopic rod. Multiple groups of positioning holes for the pin to pass through are horizontally opened on the telescopic rod. Finally, driven by the second cylinder, the telescopic column drives the rectangular telescopic sleeve to move downward along the circular telescopic sleeve to a suitable height. Thus, after the liquid medicine is sprayed, it is evenly leveled to avoid uneven spraying and affecting the quality and effect of the medicine film.

[0011] Preferably, a display panel is installed in the middle of one side of the heating bin. Multiple groups of heating lamps are horizontally installed at intervals above the inner side of the heating bin. A heating driver connected to the heating lamps is installed at the corner of the side of the heating bin where the display panel is installed. Sliding grooves are symmetrically opened at the edges on both sides of one side of the heating bin. A placement box is provided on one side of the heating bin. Connecting rods are installed on both sides of the placement box. A rectangular slider is installed at the end of the connecting rod away from the placement box. A driver is installed inside the rectangular slider. The rectangular slider drives the connecting rod to be slidably connected to the heating bin along the sliding groove. A telescopic valve is installed on one side of the placement box. An electromagnetic control valve is installed on one side of the telescopic valve. Multiple groups of micro cameras are horizontally installed above the inner side of the placement box. When the raw material film body is evenly coated, it is moved into the heating bin. Then, driven by the driver, the rectangular slider drives the connecting rod to be slidably connected to the heating bin along the sliding groove. Thus, the placement box is driven to move downward to be close to the raw material film body. Then, controlled by the electromagnetic control valve, the telescopic valve contracts, so that the test insects fall onto the medicine film and crawl to fully contact the medicine film. During this process, driven by the heating driver, the heating lamps start to emit heat, so that the test insects are in a constant temperature environment. Finally, the situation of the test insects can be monitored in real time through the micro cameras, and the situation of the constant temperature environment can be understood in real time through the display panel, which is convenient for timely adjustment.

[0012] The beneficial effects of the present utility model:

[0013] 1. Different from the situation in the past where the coating of the liquid medicine on the medicine film may be uneven during the production process of the medicine film because most of the production machines are used for one-way assembly, which affects the quality and effect of the medicine film. When making a medicine film, first, driven by the first motor, the first rotating shaft rotates along the first vertical plate, driving the raw material film body to unwind. Then, driven by the second motor, the second rotating shaft rotates along the second vertical plate, driving the raw material film body to wind up. Thus, the raw material film body can smoothly and continuously proceed to the next process. According to the width of the raw material film body, through the adjustment of the pin, the telescopic rod moves horizontally along the rectangular telescopic sleeve to an appropriate width, and then the pin passes through the rectangular telescopic sleeve and is fixedly connected to the telescopic rod through the positioning hole. Then, the liquid medicine is poured into the liquid supply tank through the liquid inlet pipe. Then, driven by the water pump, the liquid medicine enters the connecting pipe from the liquid supply tank and is sprayed onto the raw material film body through the liquid outlet pipe to form the required medicine film. Finally, driven by the second cylinder, the telescopic column drives the rectangular telescopic sleeve to move downward along the circular telescopic sleeve to an appropriate height. Thus, after the liquid medicine is sprayed, it is evenly leveled to avoid uneven spraying, which affects the quality and effect of the medicine film. At the same time, during the production process of the medicine film, the support column plays a role in firmly supporting the operating table.

[0014] 2. After the raw material film body is evenly coated, it is moved into the heating chamber. Then, driven by the driver, the rectangular slider drives the connecting rod to slide along the sliding groove and is connected to the heating chamber, thereby driving the placement box to move downward to be close to the raw material film body. Then, through the control of the electromagnetic control valve, the telescopic valve contracts, causing the test insects to fall onto the medicine film and crawl to fully contact the medicine film. During this process, driven by the heating driver, the heating lamp tube starts to emit heat, making the test insects in a constant temperature environment. Finally, the situation of the test insects can be monitored in real time through the micro camera, and at the same time, the situation of the constant temperature environment can be understood in real time through the display panel, which is convenient for timely adjustment.

[0026] When working, when it is necessary to produce a medicine film, first, driven by the first motor 202, the first rotating shaft 203 rotates along the first vertical plate 201, driving the raw material film body 204 to unwind. Then, driven by the second motor 206, the second rotating shaft 207 rotates along the second vertical plate 205, driving the raw material film body 204 to wind up. Thus, the raw material film body 204 can smoothly and continuously proceed to the next process.

[0027] According to the width of the raw material film body 204, through the adjustment of the bolt 410, the telescopic rod 411 moves horizontally along the rectangular telescopic sleeve 409 to an appropriate width. Then, the bolt 410 passes through the rectangular telescopic sleeve 409 and is positioned and connected to the telescopic rod 411 through the positioning hole. Next, the liquid medicine is poured into the liquid supply tank 401 through the liquid inlet pipe 404. Then, driven by the water pump 405, the liquid medicine enters the connecting pipe 402 from the liquid supply tank 401 and is sprayed onto the raw material film body 204 through the liquid outlet pipe 403 to form the required medicine film. Finally, driven by the second cylinder 406, the telescopic column 408 drives the rectangular telescopic sleeve 409 to move downward along the circular telescopic sleeve 407 to an appropriate height. Thus, after the liquid medicine is sprayed, it is evenly leveled to avoid uneven spraying, which affects the quality and effect of the medicine film. At the same time, during the production process of the medicine film, the support column 102 plays a role in firmly supporting the operating table 101;

[0028] During the transmission of the raw material film body 204, according to the width of the raw material film body 204, driven by the first cylinder 302, the telescopic plate 303 drives the convex limiting plate 304 to move horizontally along the L-shaped telescopic sleeve 301 to approach the raw material film body 204 until the rectangular soft pad 305 fits the raw material film body 204 to limit it, avoiding the deviation of the raw material film body 204 during the conveying process and ensuring that the raw material film body 204 can be accurately aligned and positioned. The rectangular soft pad 305 can prevent the raw material film body 204 from being worn;

[0029] When the raw material film body 204 is evenly coated, it moves into the heating chamber 5. Then, driven by the driver, the rectangular slider 505 drives the connecting rod 506 to slide along the sliding groove 504 and is slidably connected to the heating chamber 5, thereby driving the placement box 507 to move downward to approach the raw material film body 204. Then, through the control of the electromagnetic control valve 509, the telescopic valve 508 contracts, causing the test insects to fall onto the medicine film and crawl to fully contact the medicine film. During this process, driven by the heating driver 502, the heating lamp tube 503 starts to emit heat, enabling the test insects to be in a constant temperature environment. Finally, the situation of the test insects can be monitored in real time through the micro camera 510, and the situation of the constant temperature environment can be understood in real time through the display panel 501, which is convenient for timely adjustment.

[0030] Through the above steps, when making a medicine film, first, driven by the first motor 202, the first rotating shaft 203 rotates along the first vertical plate 201, driving the unwinding of the raw material film body 204. Then, driven by the second motor 206, the second rotating shaft 207 rotates along the second vertical plate 205, driving the winding of the raw material film body 204. Thus, the raw material film body 204 can smoothly and continuously proceed to the next process. According to the width of the raw material film body 204, through the adjustment of the bolt 410, the telescopic rod 411 moves horizontally along the rectangular telescopic sleeve 409 to an appropriate width, and then the bolt 410 passes through the rectangular telescopic sleeve 409 and is positioned and connected to the telescopic rod 411 through the positioning hole. Then, the liquid medicine is poured into the liquid supply tank 401 through the liquid inlet pipe 404. Then, driven by the water pump 405, the liquid medicine enters the connecting pipe 402 from the liquid supply tank 401 and is sprayed onto the raw material film body 204 through the liquid outlet pipe 403 to form the required medicine film. Finally, driven by the second cylinder 406, the telescopic column 408 drives the rectangular telescopic sleeve 409 to move downward along the circular telescopic sleeve 407 to an appropriate height. Thus, after the liquid medicine is sprayed, it is evenly smoothed to avoid uneven spraying, which affects the quality and effect of the medicine film. At the same time, during the production of the medicine film, the support column 102 plays a role in firmly supporting the operating table 101.
