Description

Technical Field

[0001] The invention relates to the technical field of correction fluid production, and more specifically to an automatic liquid-adding and sealing device for correction fluid production. Background Art

[0002] With the continuous advancement of science and technology, correction fluid is widely used as a convenient tool. In the process of production of correction fluid, an automatic liquid adding and sealing device for correction fluid production is needed. The automatic liquid adding and sealing device for correction fluid production is a device that injects correction fluid into a specific device and seals it during the production of correction fluid. The automatic liquid adding and sealing device for correction fluid production is mainly composed of a shell component, a connecting component, a power component and a liquid adding component. The automatic liquid adding and sealing device for correction fluid production has the advantages of fast liquid adding speed and good liquid adding effect.

[0003] The common automatic liquid filling and sealing device for correction fluid production generally has the following defects during use:

[0004] First, during the use of the common automatic liquid filling and sealing device for correction fluid production, the correction fluid is directly injected into the storage device through the filling pipe during the filling process. During the filling process, the amount of correction fluid added to the device cannot be observed, resulting in a poor filling effect. In addition, during the filling process, direct filling will directly inject impurities in the filling fluid into the device, which is not conducive to the filling of the correction fluid.

[0005] Second, in the process of using the common automatic filling and sealing device for correction fluid production, after filling, the equipment after filling is directly sealed. Since there are multiple raw materials mixed in the filling liquid, the filling liquid is not mixed thoroughly, making the filling liquid effect after filling poor;

[0006] Thirdly, during the use of the common automatic liquid filling and sealing device for correction fluid production, the sealing device will be moved to a specific position and started only after the filling is completed, thereby realizing the sealing operation of the filling device. The whole process takes a lot of time, which reduces the sealing efficiency;

[0007] In summary: the common automatic liquid filling and sealing device for correction fluid production has the following defects during use: direct filling will directly inject impurities in the filling liquid into the equipment, and the filling liquid is not mixed thoroughly due to the presence of multiple raw materials in the filling liquid, and the sealing operation of the filling equipment requires a lot of time.

A sliding groove 805 connected to the storage groove is opened on the side of the support platform 5, and two sliding grooves 805 are slidably connected inside. The movable plate 806 and the power rod 803 are located inside the sliding groove 805 and are threadedly connected to the two sliding plates 806. A rotating rod 807 is rotatably connected to the side wall of the storage tank 702. A second gear 808 is sleeved on the outer wall of the rotating rod 807. A threaded rod 809 is rotatably connected to the bottom of one of the telescopic grooves 708. The threaded rod 809 is threadedly connected to one of the telescopic rods 709. One end of the rotating rod 807 is located inside the telescopic groove 708 and a bevel gear set 810 is sleeved on the outer wall of the threaded rod 809.

[0040] What needs to be specially explained in this embodiment is that: when the storage tank 702 descends to a specific position, the first gear 802 is meshed with the second gear 808, and the telescopic rod 709 descends in the telescopic groove 708 to realize the rotation of the threaded rod 809, and the rotation rod 807 is rotated under the action of the bevel gear set 810, and the rotation of the rotating rod 801 is realized. Under the action of the transmission wheel set 804, the power rod 803 is rotated, and the two sliding plates 806 are reciprocated. Since the upper surface of the sliding plate 806 is arranged in an inclined structure, the storage tank 6 is shaken up and down to achieve the mixing of the correction fluid.

[0041] Reference Figure 7 The upper surface of the sliding plate 806 is arranged in an inclined structure, and a double-start thread is arranged on the outer wall of the power rod 803.

[0044] What needs to be specially explained in this embodiment is that: when the correction fluid inside the storage tank 703 completely enters the storage tank 6, under the action of the spring 707, the storage tank 702 is restored to its original position, the blocking plate 903 leaves the conductive slot 902, and the conductive slot 902 supplies power to the sealer to achieve sealing of the equipment. Since the sealer is located on the inner wall of the storage tank 6, the sealing efficiency is relatively high.

[0045] Reference Figure 8 A conductive layer is provided inside the conductive groove 902, the conductive plate 901 is made of insulating material, the conductive groove 902 is connected to the power source body, and the other end of the conductive groove 902 is connected to a sealer, which is an electrically heated seal and is located on the inner wall of the storage tank 6.

[0046] It should be particularly noted in this embodiment that when the blocking plate 903 leaves the conductive slot 902 , the conductive slot 902 will supply power to the sealer to achieve sealing of the device.

[0047] The working principle of the present invention is as follows: when it is necessary to add correction fluid, the storage tank 4 is started, and the correction fluid inside the storage tank 4 is injected into the storage tank 703 through the discharge pipe. As the correction fluid inside the storage tank 703 is continuously injected, the storage tank 703 drives the lifting plate 701 to continuously descend and enter the storage tank 6. At the same time, the lifting rod 706 descends under the action of the lifting plate 701 and compresses the spring 707, and the blocking plate 903 enters the conductive slot 902 to block the conductive slot 902 and stop the sealer.

[0048] When the storage tank 702 drops to a specific position, the squeezing rod 710 squeezes the squeezing block 711, so that the squeezing block 711 enters the through groove and the connecting block 714 slides inside the connecting groove 715. When the connecting block 714 slides to the notch, under the action of gravity, the telescopic rod 709 drops in the telescopic groove 708, so that the bottom plate 704 is separated from the storage tank 702, and the correction fluid in the storage groove 703 enters the storage tank 6, so that the quantitative correction fluid is added;

[0049] At the same time, when the storage tank 702 descends to a specific position, the first gear 802 meshes with the second gear 808, and the telescopic rod 709 descends in the telescopic slot 708 to realize the rotation of the threaded rod 809, and the rotation rod 807 rotates under the action of the bevel gear set 810, and the rotation rod 801 rotates, and the power rod 803 rotates under the action of the transmission wheel set 804, and the two sliding plates 806 reciprocate. Since the upper surface of the sliding plate 806 is arranged in an inclined structure, the storage tank 6 is shaken up and down to achieve mixing of the correction fluid;

[0050] When the correction fluid inside the storage tank 703 completely enters the storage tank 6, under the action of the spring 707, the storage tank 702 is restored to its original position, the blocking plate 903 leaves the conductive slot 902, and the conductive slot 902 supplies power to the sealer to achieve sealing of the equipment. Since the sealer is located on the inner wall of the storage tank 6, the sealing efficiency is relatively high.
