[0021] The present invention will be further described below with reference to the embodiments.
[0022] Please see Figure 1-4 This utility model provides a multifunctional liquid additive filling device, including a main cylinder 1, a feed inlet 2, and a filling port 3. The feed inlet 2 is fixedly connected to the top of the main cylinder 1 and is used to connect to the additive delivery pipeline. The filling port 3 is fixedly connected to the bottom of the main cylinder 1. A control valve 301 is installed on the filling port 3 to control the opening and closing of the feed pipeline of the filling port 3. An installation frame 4 is fixedly connected to the main cylinder 1. An installation plate 5 is fixedly connected to the right side surface of the installation frame 4. A motor 6 is fixedly installed on the installation frame 4 through the installation plate 5. A rotating connection mechanism 7 is provided at the output end of the motor 6 and is located on the installation frame 4. A quantitative adjustment mechanism 8 is provided between the main cylinder 1 and the installation frame 4 and is connected to the rotating connection mechanism 7.
[0023] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the rotating connection mechanism 7 includes a connecting cylinder 701, which is fixedly connected to the output end of the motor 6. The connecting cylinder 701 is rotatably mounted on the mounting frame 4 via bearings. A connecting rod 702 is slidably mounted inside the connecting cylinder 701. A limit block 703 is fixedly connected to the outer side of the right end of the connecting rod 702. The limit block 703 has a matching limit groove 704 inside the connecting cylinder 701. Four limit blocks 703 are evenly arranged on the connecting rod 702. Four limit grooves 704 are matched with the limit blocks 703 inside the connecting cylinder 701. The connecting rod 702 is rotatably mounted on the connecting cylinder 701 via the limit blocks 704. Position block 703 and limiting groove 704 slide within connecting cylinder 701. A first spring 705 is fixedly installed on the right side of connecting rod 702 within connecting cylinder 701. A first extrusion block 706 is fixedly connected to the outer side of the left end of connecting rod 702. A second extrusion block 707 is provided on the outer side of the left side of the first extrusion block 706. An installation groove 708 is provided on the corresponding position of the second extrusion block 707 on the quantitative adjustment mechanism 8. The second extrusion block 707 is fixedly connected to the quantitative adjustment mechanism 8 through the installation groove 708. The first extrusion block 706 and the second extrusion block 707 are centrally symmetrically arranged along the axis of connecting rod 702.
[0024] In use, the motor 6 operates, causing the connecting cylinder 701 to rotate, which in turn drives the connecting rod 702 to rotate on the connecting cylinder 701 via the limiting block 703. At this time, the rotation of the connecting rod 702, combined with the elastic force of the first spring 705, causes the first extrusion block 706 to extrude friction against the second extrusion block 707. Under the friction and extrusion of the first extrusion block 706, the second extrusion block 707 rotates, which in turn causes the gear 8010 to rotate within the mounting frame 4 via the rotating groove 8011. The rotation of the gear 8010 quantitatively delivers the additive inside the main cylinder 1. By controlling the speed of the motor 6, the rotation process of the connecting cylinder 701 is controlled, thereby controlling the activity time of the movable block 802. This enables the timed delivery and discharge of the additive, thus improving the practicality of the device.
[0025] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the quantitative adjustment mechanism 8 includes two through slots 801 and two movable blocks 802. The two through slots 801 are opened on the surface of the main cylinder 1 and are spaced apart. The two movable blocks 802 are slidably disposed inside the main cylinder 1 and are symmetrically arranged in the center of the main cylinder 1. A sealing layer 803 is provided on the outer surface of the movable blocks 802. The sealing layer 803 is made of rubber material and is set to match the inner diameter of the main cylinder 1 through the movable blocks 802. The two movable blocks 802 have beveled openings 804 on one side close to each other. A connecting plate 805 is fixedly connected to the surface of the movable blocks 802 corresponding to the through slots 801. The connecting plate 805 is disposed through the main cylinder 1 through the through slots 801. The outer side of the connecting plate 805 is fixedly connected to A rack 806 is provided, and a gear 8010 is meshed on the outside of the rack 806. A rotating groove 8011 is provided on the left side of the gear 8010 corresponding to the surface of the main cylinder 1. The gear 8010 is rotated on the main cylinder 1 through the rotating groove 8011. A fixing plate 807 is fixedly connected to the top of the rack 806 away from the rack 806. A guide rod 808 is slidably provided on the fixing plate 807. A second spring 809 is sleeved on the outside of the guide rod 808. The guide rod 808 is fixedly connected in the mounting frame 4. The second spring 809 is provided between the fixing plate 807 and the mounting frame 4 through the guide rod 808. A connecting plate 805 and the rack 806 are centrally symmetrically arranged on the outside of the rotating groove 8011 through a movable block 802. A mounting groove 708 is opened on the right side of the gear 8010.
[0026] In use, the rotation of gear 8010 causes connecting plate 805 to slide through rack 806, which in turn causes fixed plate 807 to slide on guide rod 808 and compress second spring 809. The sliding of connecting plate 805 causes two movable blocks 802 to slide inside main cylinder 1, thereby forming a channel between the two movable blocks 802 through inclined opening 804. At this time, additive is transported through the channel to the bottom of main cylinder 1 for accumulation, thereby performing a quantitative additive filling operation.
[0027] This solution has the following working process: When this device is in use, the additive is transported into the main cylinder 1 through the feed pipe connected to the feed port 2. At this time, with the movable block 802 in place, the additive accumulates in the upper part of the main cylinder 1. The motor 6 runs, causing the connecting cylinder 701 to rotate, thereby driving the connecting rod 702 to rotate on the connecting cylinder 701 through the limiting block 703. At this time, through the rotation of the connecting rod 702, and in conjunction with the elastic force of the first spring 705, the first extrusion block 706 can extrude friction against the second extrusion block 707, thereby achieving the desired effect in the first extrusion block. The friction and compression of block 706 causes the second compression block 707 to rotate, which in turn causes gear 8010 to rotate within the mounting frame 4 via the rotating groove 8011. The rotation of gear 8010 causes connecting plate 805 to slide via rack 806, which in turn causes fixed plate 807 to slide on guide rod 808 and compress the second spring 809. The sliding of connecting plate 805 causes two movable blocks 802 to slide within the main cylinder 1, thus forming a channel between the two movable blocks 802 via inclined opening 804. At this time, additives are delivered through the channel. The material is fed to the bottom of the main cylinder 1 and accumulates. As the fixed plate 807 compresses the second spring 809, when the elastic potential energy of the second spring 809 increases to exceed the elastic potential energy of the first spring 705, the gear 8010 cannot drive the rack 806 to rotate. At this time, the second compression block 707 compresses the first compression block 706, causing the first compression block 706 to slide on the connecting cylinder 701 through the connecting rod 702 and compress the first spring 705. This results in a misaligned movement between the first compression block 706 and the second compression block 707. When the first extrusion block 706 and the second extrusion block 707 are misaligned, the second spring 809 causes the fixed plate 807 to drive the connecting plate 805 and the rack 806 to reset, thereby closing the channel between the movable blocks 802. This allows for the injection of a fixed amount of additive. The fixed amount of additive is then discharged through the injection port 3 under the control of the control valve 301. Furthermore, the movement time of the movable block 802 can be controlled by controlling the speed of the motor 6, thus enabling the timed delivery and discharge of additives and improving the practicality of the device.
[0028] In summary: By using the rotating connection mechanism 7 in conjunction with the quantitative adjustment mechanism 8, the operating speed of the rotating connection mechanism 7 can be adjusted to match the quantitative adjustment mechanism 8 during the filling process. This allows for the timely and quantitative adjustment of the additive filling process based on the filling process, thereby improving the filling efficiency of the additive.
