Abstract
Description
Technical Field
[0001] This utility model relates to the field of anhydrous acetonitrile filling technology, specifically to an automatic anhydrous acetonitrile filling device. Background Technology
[0002] Anhydrous acetonitrile has high solubility and volatility, and can dissolve many organic and inorganic substances. In organic synthesis, anhydrous acetonitrile is often used as a solvent or reaction intermediate to promote chemical reactions.
[0003] After acetonitrile-related products are manufactured, filling equipment is often used to fill the acetonitrile for storage and subsequent sales.
[0004] A Chinese patent application (CN202322764486.3) discloses an automatic filling device for dichloroacetonitrile, which includes: "a base plate, on which a support frame is attached, within which a support frame is attached, an electric push rod is installed within the support frame and connected to the support frame, two positioning components are installed within the support frame, and two piston cylinders are installed within the support frame. This automatic filling device for dichloroacetonitrile, through the arrangement of the electric push rod, piston cylinders, piston frame, automatic filling tube, support frame, and clamping plate, facilitates the placement and removal of the collection tank within the support frame, and allows the automatic filling tube to be positioned inside the collection tank, resulting in accurate filling and less spillage. Furthermore, it avoids the safety risks of direct manual contact, thus ensuring a safe and reliable filling process."
[0005] We found that the patents retrieved above involve a filling process that requires placing the bottle on a specific structure, feeding the bottle, filling, retrieving the bottle, and removing the bottle from the structure. Only after these operations are completed can the next bottle be installed and subsequent operations begin. This results in an incoherent filling process that consumes more time, making it difficult to quickly proceed with the next filling operation. Consequently, the filling efficiency of the product is affected, which is not conducive to improving the company's production efficiency. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-4 An automatic acetonitrile filling device includes a fixed base 1. A first conveyor platform 2 and a second conveyor platform 3 are fixedly mounted on the top of the fixed base 1. The first conveyor platform 2 and the second conveyor platform 3 are fixedly connected and form a "T" shape. The connection between the two platforms allows the bottle body 4 to easily enter the second conveyor platform 3 from the first conveyor platform 2, quickly completing the movement and filling of the bottle body 4. The top of the first conveyor platform 2, the top of the lifting plate 21, and the top of the padding plate 19 are all designed with a smooth mirror surface structure, which facilitates the sliding of the bottle body 4. Protective plates 13 are fixed on both sides of the top of the first conveyor platform 2. The two protective plates 13 limit and protect the bottle body 4 on the first conveyor platform 2, ensuring that the bottle body 4 enters the positioning groove 20 stably and accurately. A servo motor is slidably connected between the two protective plates 13. The push plate 16 driven by the electric push rod 22 is installed on one side of the top of the conveyor platform 23. The top of the conveyor platform 23 is fixed with a guard plate 27 and the top of the conveyor platform 23 is fixed with a guard plate 38. The guard plate 27 and the guard plate 38 can limit and protect the filling bottle body 4 on the conveyor platform 23, so that it remains stable when moving. The guard plate 38 has a notch and is connected to the two guard plates 13. The top of the conveyor platform 23 is fixed with a pad plate 19. The pad plate 19 has a positioning groove 20 at the position corresponding to the notch. The positioning groove 20 is provided with a lifting plate 21. The push plate 23 driven by the electric push rod 22 is provided on one side of the pad plate 19. The pad plate 19 is provided on the conveyor platform 23. The positioning groove 20 is provided on the pad plate 19. The positioning groove 20 can be used to limit and position the two sides of the filling bottle body 4, so as to ensure the stability of the filling bottle body 4 during the filling operation.
[0026] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, a baffle is fixed between the two guard plates 13 and on the side away from the notch. Guide grooves 15 are provided on the inner walls of both guard plates 13. A servo motor 14 is installed on one of the guard plates 13, and the power output shaft of the servo motor 14 moves through the corresponding guide groove 15 and is connected to a lead screw 1401. Guide slider 1601 and guide slider 2 1602 are fixed in the middle of the left and right sides of the push plate 16, respectively. Guide slider 1601 is placed in the guide groove 15 of one of the guard plates 13 and threadedly sleeved with the lead screw 1401 inside. A limiting slide rod 24 is fixed in the guide groove 15 of the other guard plate 13. Guide slider 2 1602 is placed in the guide groove 15 of the other guard plate 13 and slidably sleeved with the limiting slide rod 24 inside.
[0027] Specifically, after the servo motor 14 is started, it can drive the lead screw 1401 to rotate through its power output shaft, thereby causing the guide slider 1601 fitted with it to slide in the corresponding guide groove 15, thereby causing the entire push plate 16 to move between the two guard plates 13. In order to improve the stability of the push plate 16 during movement, a guide slider 2 1602 is also fixed on the other side of the push plate 16. The guide slider 2 1602 is slidably connected in another guide groove 15 and is limited by the limiting slide rod 24, which can further improve the stability of the push plate 16 during movement.
[0028] Please see Figure 1 and Figure 2 In this embodiment, baffles 2 and 3 are fixed between the left and right sides of guard plate 2 17 and guard plate 3 18 respectively. Electric push rod 1 22 is fixed on baffle 2. The power output shaft of electric push rod 1 22 is fixed on one side of push plate 2 23. Push plate 2 23 is slidably connected between guard plate 2 17 and guard plate 3 18.
[0029] Specifically, after the electric push rod 22 is started, its power output shaft can push the push plate 23 to move between the guard plate 27 and the guard plate 3 18. The movement of the push plate 23 pushes the filling bottle body 4 located between the guard plate 27 and the guard plate 3 18, and pushes it onto the raised plate 19 on the top right side of the conveyor platform 23, so that the staff can remove the filling bottle body 4 from the raised plate 19 on the top right side of the conveyor platform 23.
[0030] Please see Figure 1 , Figure 2 and Figure 4In this embodiment, an electric push rod 25 is installed in the inner cavity at the bottom of the positioning groove 20. The power output shaft of the electric push rod 25 extends through the positioning groove 20 and is fixed with a lifting plate 21. When the bottom of the lifting plate 21 is attached to the inner bottom wall of the positioning groove 20, the top of the lifting plate 21 is at the same horizontal line as the top of the conveyor table 2. When the lifting plate 21 is pushed out by the electric push rod 25, the top of the lifting plate 21 is at the same horizontal line as the top of the pad plate 19.
[0031] Specifically, after the electric push rod 25 is started, its power output shaft can push the lifting plate 21 to move. When lifting, it pushes the filling bottle body 4 to rise, making it easy to push away. When descending, it closes in the positioning groove 20, making it easy to push the filling bottle body 4 in, without affecting the positioning and limiting of the filling bottle body 4 by using the positioning groove 20.
[0032] Please see Figure 1 In this embodiment, a support plate 5 is also fixed on one side of the top of the fixed base 1. A storage box 6 is provided on the top of the support plate 5. A conveying pipe 7 is connected to one side of the storage box 6. A suction pump 8 is connected to the liquid outlet end of the conveying pipe 7. An outlet pipe 9 is connected to the liquid outlet end of the suction pump 8. A filling head 12 is connected to one end of the outlet pipe 9. A fixing block 11 is fixed on the top of the filling head 12. An electric telescopic rod 10 is installed on the top of the fixing block 11. The fixed end of the electric telescopic rod 10 is fixed on the support plate 5, and the telescopic end of the electric telescopic rod 10 is fixed on the fixing block 11. It also includes a filling bottle body 4. When the filling bottle body 4 is placed in the positioning groove 20, the bottle mouth of the filling bottle body 4 corresponds to the filling head 12.
[0033] Specifically, after the suction pump 8 is started, anhydrous acetonitrile can be easily introduced into the filling bottle body 4 through the filling head 12 to complete the filling. The start of the electric telescopic rod 10 can drive the filling head 12 into or away from the filling bottle body 4 for convenient use. In order to ensure that there is enough anhydrous acetonitrile in the storage tank 6, a liquid replenishment port is also provided on the top of the storage tank 6 to facilitate connection with the anhydrous acetonitrile conveying equipment and add anhydrous acetonitrile to the storage tank 6.
[0034] When using:
[0035] Place the filling bottle body 4 onto the conveyor table 2, start the servo motor 14, and the power output shaft of the servo motor 14 drives the lead screw 1401 to rotate, thereby driving the push plate 16 to move. When the push plate 16 moves, it can push the filling bottle body 4 towards one side of the positioning groove 20 until the filling bottle body 4 is placed in the positioning groove 20, thus achieving the positioning of the filling bottle body 4 (then the servo motor 14 drives the lead screw 1401 to reverse, driving the push plate 16 away from the initial position of the positioning groove 20). Then the electric telescopic rod 10 can be started. The electric telescopic rod 10 pushes the filling head 12 down and enters the filling bottle body 4 from the bottle mouth. The suction pump 8 is started, which extracts anhydrous acetonitrile from the storage tank 6 and conveys it through the outlet pipe 9 from the filling head 12 to the filling bottle body 4, completing the automatic filling of anhydrous acetonitrile into the filling bottle body 4. The electric push rod 25 is started, and the power output shaft of the electric push rod 25 pushes the lifting plate 21 to rise, which in turn lifts the filling bottle body 4. Finally, the electric push rod 22 is started, and the push plate 23 pushes the filling bottle body 4 to move to the right side of the conveyor platform 3 and stops at the top right side of the conveyor platform 3. After the filling bottle body 4 is removed from the lifting plate 21, the power output shaft of the electric push rod 25 is retracted, which drives the lifting plate 21 to descend to the initial position.
[0036] In other words, when the current bottle body 4 is being filled in the positioning groove 20, the next bottle body 4 waiting to be filled can be placed on the conveyor table 2 for preparation. This time difference is used to make use of the waiting time for filling, thereby improving operational efficiency. When the bottle body 4 in the positioning groove 20 is filled, it can be directly pushed away by the pusher plate 23, and then the next bottle body 4 waiting to be filled can be pushed into the positioning groove 20 by the pusher plate 16, thus forming a continuous working mode. Less time is wasted, automation is higher, and filling efficiency is higher.
[0037] In summary, the continuous working process is as follows: pusher plate 16 pushes the filling bottle body 4 into the positioning groove 20, filling occurs, pusher plate 16 retracts during the filling process, lifting plate 21 is raised after filling is completed so that lifting plate 21 and pad plate 19 are at the same height, pusher plate 23 pushes the filling bottle body 4 away, lifting plate 21 descends, pusher plate 23 retracts, and pusher plate 16 pushes the next filling bottle body 4 to be filled into the positioning groove 20 again.
[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
