Description

Technical Field

[0001] The invention belongs to the technical field of filling, in particular to a quantitative filling machine for liquid filling. Background Art

[0002] A filling machine is a device used to fill liquid or powder products. Its main function is to extract or push the product from the container into the filling container. Filling machines can be classified according to different packaging angles and production automation levels. The main uses of filling machines are wide-ranging, involving many industries such as food, daily chemicals, and pharmaceuticals.

[0003] Because the medical industry's liquid medicines need to be strictly quantitatively filled during production, and in order to avoid bubbles in the packaged liquid medicine, the tip of the filling machine is usually inserted into the bottom of the container. However, this will cause the actual amount of liquid put in to be greater than the capacity inside the container due to the immersion of the filling machine tip. There will be a large deviation when the actual scale line of the container is used as a reference, so the filling technology needs to be improved. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems by adopting a technical solution: a quantitative filling machine for liquid filling, comprising a transfer device, the upper surface of the transfer device is evenly provided with filling components, and the middle part of the transfer device is provided with a filling device; The transfer device comprises a transmission belt, the outer surface of which is evenly provided with a rubber soft cover, the middle of the inner wall of the transmission belt is rotatably connected with a built-in support frame, and transmission rollers are symmetrically provided on both sides of the inner wall of the transmission belt; The filling equipment comprises a side fixing plate, the top of which is fixedly connected to a lifter, the top of which is fixedly connected to a controller via a connecting plate, and a container device is arranged at the bottom of the controller; the container device comprises a container tray, and a filling assembly is arranged at the axis of the inner cavity of the container tray; The filling assembly includes a connecting slide, the inner wall of the connecting slide is slidably connected to a guide inner tube, and the controller can control the connecting slide to perform vertical sliding movement along the guide inner tube by driving the container plate, the bottom end of the guide inner tube is provided with a flow control device, and wire clamps are symmetrically provided on both sides of the outer surface of the connecting slide, the inner wall of the wire clamp is fixedly connected to a transmission wire, the actual length of the transmission wire supports the connection slide to move to the lowest point, the bottom end of the transmission wire is fixedly connected to an external casing, the top of the inner wall of the external casing is fixedly connected to an induction ring, the bottom of the inner cavity of the induction ring is evenly provided with docking rods, and the bottom end of the docking rod is fixedly connected to a buoyancy air ring. When the lower surface of the buoyancy air ring contacts the upper surface of the liquid surface, the buoyancy will cause a slight deformation to the buoyancy air ring through extrusion, thereby triggering the sensitive induction ring, and the controller can pull the container plate upward at this time.

[0005] Furthermore, the bottom end of the outer surface of the connecting slide is fixedly connected to the axis of the inner wall of the external casing, the number of the buoyancy air rings is three, the outer surface of the buoyancy air ring is fixedly connected to the bottom end of the inner cavity of the external casing through an annular groove, and the lower part of the outer surface of the buoyancy air ring extends to the outside of the external casing.

The number of the transmission wires is two, the bottom end of the transmission wire is fixedly connected to the top of the external casing through a wiring terminal, the top end of the transmission wire extends to the inner cavity of the controller through the axis guide groove, the top end of the guide inner tube is fixedly connected to the axis of the inner wall of the controller, and the top end of the guide inner tube is fixedly connected to the raw liquid tank.

[0006] Furthermore, the flow control device includes a vertical end tube, the inner cavity of the vertical end tube is uniformly provided with drainage grooves, the top of the outer surface of the vertical end tube is fixedly connected with a waterproof end sleeve, the lower surface of the waterproof end sleeve is fixedly connected with a spring soft sleeve, the bottom end of the outer surface of the vertical end tube is fixedly connected with a scanning clamp ring, and the side of the scanning clamp ring is uniformly provided with a flow meter, the filled liquid is discharged through the drainage groove, and then flows from top to bottom in contact with the inner wall of the connecting slide, and the flow meter of the scanning clamp ring performs real-time monitoring. The outer surface of the waterproof end sleeve is slidably connected to the bottom of the inner wall of the guide inner tube, the bottom end of the spring soft sleeve is fixedly connected to the bottom of the inner cavity of the vertical end tube, and the upper surface of the scanning clamp ring and the bottom end of the outer surface of the guide inner tube are pressed against each other.

[0007] Furthermore, the external protection device includes a sensing base, the outer surface of the sensing base is fixedly connected to the inner cavity of the collecting tray, the bottom of the inner cavity of the sensing base is rotatably connected to a ranging lens, the sensing base judges the distance from the bottle mouth of the container by the ranging beam of the ranging lens, thereby controlling the power of the suction pump to perform effective external dust suction, and the bottom end of the ranging lens extends to the lower part of the collecting tray, the top of the sensing base is fixedly connected to an anchor rod, the side of the anchor rod away from the sensing base is fixedly connected to the suction pump, the outer surface of the suction pump is fixedly connected to the inner cavity of the collecting tray, and the bottom end of the suction pump is fixedly connected to a filter terminal.

[0008] Furthermore, the filling component includes a filling container, a matching base is plugged into the bottom of the filling container, an internal pressure pad is fixedly connected to the bottom of the inner wall of the matching base, and indicator light panels are symmetrically arranged on the front and rear sides of the outer surface of the matching base. The bottom of the outer surface of the matching base is plugged into the inner wall of the rubber soft sleeve, the inner cavity of the indicator light panel is fixedly connected to the bottom of the inner cavity of the internal pressure pad through a wire, the interior of the filling container is plugged into the bottom end of the filling component, and the bottom of the filling container and the upper surface of the internal pressure pad are pressed against each other.

[0009] The beneficial effects of the present invention are as follows: 1. The device can fill the solution into the filling container by inserting the connecting slide into the filling container. Since the external casing is always suspended in the upper area of ​​the liquid surface, the problem of bacterial contamination caused by the connecting slide being immersed in the solution for a long time can be avoided. When the bottom of the connecting slide sprays liquid, since the solution hardly contacts the air during the falling process, the device can ensure that the solution inside the filling container does not generate a large number of bubbles under the condition of a fast filling speed, thereby ensuring the purity of the solution.

[0010] 2. An external casing is provided at the bottom end of the connecting slide. Through the sensitive sensing effect of the buoyancy air ring, the connecting slide gradually rises as the liquid level inside the bottle increases during the filling process. Therefore, the connecting slide will not be inserted into the interior of the solution, resulting in an error in the amount of filling solution input due to the immersion of the bottom end of the connecting slide in the filling container.

[0011] 3. When filling the solution, the solution flows from top to bottom along the inner wall of the connecting slide under the guidance of the drainage groove. After the filling is completed, due to the cessation of pressurization, the vertical end tube will slide up under the elastic force of the spring soft sleeve, and then immediately block the drainage groove to avoid dripping, ensure the accuracy of the liquid capacity inside the filling container, and judge whether there is dripping or leakage at the bottom of the guiding inner tube through the flow meter, thereby ensuring the sealing of the flow control equipment during non-infusion work.

[0012] 4. Since the container tray is always at the top of the bottle mouth of the filling container, and the dust in the external air may fall into the inside of the filling container during filling, the suction pump will generate suction on the outside of the bottle mouth, thereby avoiding the problem of dust falling on the bottle mouth of the filling container during the filling process. The suction power of the suction pump is dynamically adjusted from small to large. Compared with directly using a large power for adsorption work, the actual energy consumption of the suction pump can be reduced, and the problem of the filter end being under high-power adsorption for a long time, which quickly deteriorates the internal filtration effect, can be avoided.

[0017] The bottom end of the outer surface of the connecting slide 51 is fixedly connected to the axis of the inner wall of the external casing 55. There are three buoyancy air rings 56. The outer surface of the buoyancy air ring 56 is fixedly connected to the bottom end of the inner cavity of the external casing 55 through an annular groove, and the lower part of the outer surface of the buoyancy air ring 56 extends to the outside of the external casing 55. An axis guide groove 411 is provided at the axis of the inner cavity of the collection tray 41, and the inner cavity of the collection tray 41 is evenly provided with an external protection device 43 through the axis guide groove 411. A docking hole 412 is evenly provided at a position away from the axis of the inner cavity of the collection tray 41, and a traction connecting pipe 42 is evenly fixed to the inner cavity of the collection tray 41 through the docking hole 412. The top end of the traction connecting pipe 42 is fixedly connected to the bottom of the inner cavity of the controller 33. There are two transmission wires 54, the bottom end of the transmission wire 54 is fixedly connected to the top of the external casing 55 through a wiring terminal, the top end of the transmission wire 54 extends to the inner cavity of the controller 33 through the axial guide groove 411, the top end of the guide inner tube 52 is fixedly connected to the axis of the inner wall of the controller 33, and the top end of the guide inner tube 52 is fixedly connected to the raw liquid tank.

[0018] After the filling component 2 is placed on the rubber soft cover 12 of the transmission conveyor belt 11, the transmission conveyor belt 11 transports the container to the central position, and then the filling work is carried out.

[0019] After the lifter 32 lowers the controller 33 and the container equipment 4, the filling assembly 5 is inserted into the filling container 21 along the axis. Figure 1 As shown, in order to avoid the appearance of a large number of bubbles, the controller 33 will push the collection plate 41 downward by pulling the connecting tube 42. At this time, the connecting slide 51 slides down relative to the guiding inner tube 52, and then the bottom end of the connecting slide 51, that is, the external sleeve 55 moves to a deeper area of ​​the filling container 21, and then the inner tube 52 is guided to fill the interior of the container. Subsequently, the liquid surface below quickly contacts the buoyancy air ring 56 at the bottom. When the buoyancy air ring 56 triggers the induction ring 58 due to the pressure of the liquid surface, the controller 33 will push the collection plate 41 upward through the electrical signal transmitted by the transmission wire 54, so that the bottom of the filling component 5 is suspended a certain distance in the air, but not immersed in the liquid, so as to ensure the purity of the solution.

[0020] When the solution is being filled, the controller 33 always performs dynamic fine-tuning on the collecting tray 41 until the amount of solution in the filling container 21 reaches the standard, then completely pulls the filling component 5 out of the filling container 21, and then seals the filling container 21 through the packaging equipment of the assembly line, and then the transmission belt 11 transports the container to the right for storage and transportation.

[0021] Example 2, please refer to Figure 1-Figure 11The present invention provides a technical solution: on the basis of the first embodiment, the flow control device 6 comprises a vertical end tube 61, the inner cavity of the vertical end tube 61 is uniformly provided with drainage grooves 62, the top of the outer surface of the vertical end tube 61 is fixedly connected with a waterproof end sleeve 64, the lower surface of the waterproof end sleeve 64 is fixedly connected with a spring soft sleeve 63, the bottom end of the outer surface of the vertical end tube 61 is fixedly connected with a scanning clamp ring 65, and the side of the scanning clamp ring 65 is uniformly provided with a flow meter 66, the filled liquid is discharged through the drainage groove 62, and then flows from top to bottom in contact with the inner wall of the slide 51, and the flow meter 66 of the scanning clamp ring 65 performs real-time monitoring. The outer surface of the waterproof end sleeve 64 is slidably connected to the bottom of the inner wall of the guide inner tube 52, the bottom end of the spring soft sleeve 63 is fixedly connected to the bottom of the inner cavity of the vertical end tube 61, and the upper surface of the scanning clamp ring 65 and the bottom end of the outer surface of the guide inner tube 52 are pressed against each other.

[0022] The external protection device 43 includes a sensing base 431, the outer surface of the sensing base 431 is fixedly connected to the inner cavity of the collecting tray 41, the bottom of the inner cavity of the sensing base 431 is rotatably connected to a ranging lens 432, the sensing base 431 determines the distance to the bottle mouth of the container through the ranging beam of the ranging lens 432, thereby controlling the power of the suction pump 434 to perform effective external dust suction, and the bottom end of the ranging lens 432 extends to the lower part of the collecting tray 41, the top of the sensing base 431 is fixedly connected to an anchor rod 433, the side of the anchor rod 433 away from the sensing base 431 is fixedly connected to the suction pump 434, the outer surface of the suction pump 434 is fixedly connected to the inner cavity of the collecting tray 41, and the bottom end of the suction pump 434 is fixedly connected to a filter terminal 435.

[0023] The filling component 2 includes a filling container 21, a matching base 22 is plugged into the bottom of the filling container 21, an internal pressure pad 24 is fixedly connected to the bottom of the inner wall of the matching base 22, and an indicator light board 23 is symmetrically arranged on the front and rear sides of the outer surface of the matching base 22. The bottom of the outer surface of the matching base 22 is plugged into the inner wall of the rubber soft cover 12, the inner cavity of the indicator light board 23 is fixedly connected to the bottom of the inner cavity of the internal pressure pad 24 through a wire, the interior of the filling container 21 is plugged into the bottom end of the filling component 2, and the bottom of the filling container 21 and the upper surface of the internal pressure pad 24 are pressed against each other.

[0024] When filling the solution, the hydraulic pressure will push the internal vertical end tube 61 to slide down relative to the guiding inner tube 52, causing the drainage groove 62 to slide out from the bottom of the guiding inner tube 52, and then the solution will flow from top to bottom along the inner wall of the connecting slide tube 51 under the guidance of the drainage groove 62. After the filling is completed, the pressurization is stopped, and the vertical end tube 61 will slide up under the elastic force of the spring soft sleeve 63, and then immediately block the drainage groove 62 to avoid dripping, thereby ensuring the accuracy of the liquid capacity inside the filling container 21, and judging whether there is any dripping or leakage at the bottom of the guiding inner tube 52 through the flow meter 66.

[0025] Since the collecting tray 41 is always at the top of the bottle mouth of the filling container 21, dust in the external air may fall into the interior of the filling container 21 during filling, so the suction pump 434 will generate suction on the outside of the bottle mouth, thereby avoiding the problem of dust falling on the bottle mouth of the filling container 21 during the filling process. The collecting tray 41 will gradually move away from the filling container 21 during the filling operation. During this process, the ranging lens 432 will increase the suction power of the suction pump 434 according to the increase in distance, thereby avoiding the problem of insufficient suction after the suction pump 434 is pulled away.

[0026] When the filling container 21 is filled inside the filling container 21, its own weight will continue to increase, so the pressure on the internal pressure pad 24 will continue to increase. When the pressure on the internal pressure pad 24 reaches the standard, the indicator light board 23 will immediately stop the filling work through a light prompt. After transporting the filling container 21, the filling container 21 can be pulled out from the inside of the rubber soft cover 12, so that the filling work can be completed accurately and efficiently when it is difficult to observe the scale.

[0027] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
