Technical Field

[0001] This utility model relates to the field of eye patch production technology, and in particular to a quantitative liquid dispensing device for eye patch production. Background Technology

[0002] Eye patches are products designed to protect and relieve eye fatigue. They relieve eye strain, moisturize the eye area, and alleviate dryness. During the packaging and production process, eye patch solution is typically filled into the packaging. The main function of the solution is to moisturize the eye patch and hydrate the skin around the eyes during use. A dispensing device is usually required during the filling process.

A liquid storage tank is also fixedly connected to the back of the fixed platform. The packaged eye patches are placed on a conveying assembly. The conveying assembly is activated to move the package below a quantitative dispensing mechanism. A lifting assembly is activated to drive the quantitative dispensing mechanism into the package. The quantitative dispensing mechanism is then activated, and a suction mechanism draws the eye patch liquid through the dispensing mechanism into the eye patch package. The flow rate of the eye patch liquid is controlled by the quantitative dispensing mechanism to complete the quantitative liquid injection. Repeating the above steps allows for continuous liquid injection and filling. This achieves the goal of easily controlling the quantitative amount of eye patch liquid during filling, avoiding the problems of inconsistent packaging quality and low filling efficiency caused by the difficulty in controlling the amount of eye patch liquid dispensed by existing dispensing devices.

[0004] The existing technology has the following problems:

[0005] The device uses a flow sensor to detect the eye patch fluid flowing through it. However, this method can cause some eye patch fluid to remain around the flow sensor when the solenoid valve is closed due to liquid tension and other factors. As the device operates, this fluid may drip due to vibration, affecting the hygiene of the device. Utility Model Content

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5As shown, a quantitative liquid dispensing device for eye patch production includes a base 1, a conveyor belt 2 movably installed on the inner side of the base 1, a vertical platform 3 fixedly connected to the middle of the upper side of the base 1 near the rear side, a telescopic rod 4 fixedly connected to the lower side of the upper wall of the vertical platform 3 near the rear side, a fixed frame 5 fixedly connected to the lower side of the telescopic rod 4, and a quantitative mechanism 6 fixedly connected to the inner side of the fixed frame 5.

[0027] The metering mechanism 6 includes a liquid storage tube 61. The outer side of the liquid storage tube 61 is fixedly connected to the inner side of the fixing frame 5 near the bottom. A threaded seat 62 is rotatably connected to the upper side of the liquid storage tube 61. A screw 63 is threadedly connected to the inner side of the threaded seat 62. A piston 64 is fixedly connected to the lower side of the screw 63. The outer side of the piston 64 is movably sleeved on the inner side of the telescopic rod 4. A solenoid valve 65 is fixedly connected to the upper side of the piston 64 near the front. A hose 66 is fixedly connected to the input end of the solenoid valve 65. An injection head 67 is fixedly connected to the lower side of the liquid storage tube 61.

[0028] It should be noted that the upper side of the tubing 66 is connected to the storage tank for storing the eye patch solution. The solenoid valve 65 is used to control the opening and closing of the lower side of the tubing 66. By rotating the threaded seat 62, the threaded seat 62 drives the screw 63 to move up and down, thereby controlling the height of the piston 64. When the solenoid valve 65 is opened, the eye patch solution is poured into the storage tube 61. Then, a miniature pump is provided on the inner side of the injection head 67 to pour the eye patch solution in the storage tube 61 downward. Since no flow sensor or other components are required on the lower side of the injection head 67, the bottom of the injection head 67 is smooth and flat, which facilitates hydrophobic treatment and avoids the retention of a small amount of eye patch solution.

[0029] like Figure 4 As shown, a ceramic ring 68 is fixedly sleeved on the inner side of the liquid storage tube 61 near the front, and the outer side of the hose 66 is movably sleeved on the inner side of the ceramic ring 68.

[0030] It should be noted that the ceramic ring 68 is used to prevent the hose 66 from contacting the upper wall of the liquid storage tube 61, which would cause wear on the liquid storage tube 61.

[0031] like Figure 4 As shown, a liquid level sensor 612 is fixedly connected to the lower side of the piston 64.

[0032] It should be noted that the liquid level sensor 612 is used to detect the amount of eye patch liquid in the reservoir tube 61. When the eye patch liquid comes into contact with the liquid level sensor 612, the liquid level sensor 612 can also measure the liquid level height, and the solenoid valve 65 is closed. The liquid level sensor 612 is provided with multiple circular holes that pass through the piston 64 to prevent the part of the reservoir tube 61 below the piston 64 from forming a low-pressure state when the injection head 67 draws out the eye patch liquid in the reservoir tube 61.

[0033] like Figure 4As shown, two second limiting rods 610 are fixedly connected to the upper side of the piston 64, which are distributed on the left and right. The outer side of the second limiting rod 610 is movably sleeved on the inner side of the upper wall of the liquid storage tube 61.

[0034] It should be noted that the second limiting rod 610 is used to limit the piston 64 and prevent the screw 63 from rotating with the threaded seat 62.

[0035] like Figure 4 As shown, the liquid storage tube 61 is made of transparent material.

[0036] It should be noted that the transparent material makes it easy to observe the liquid storage tube 61 from the outside, which facilitates understanding the operating status of the equipment.

[0037] like Figure 5 As shown, a limiting component 69 is fixedly connected to the upper side of the liquid storage tube 61 near the rear side. The limiting component 69 includes a mechanism seat 691. The lower side of the mechanism seat 691 is fixedly connected to the upper side of the liquid storage tube 61 near the rear side. Two first limiting rods 692 are fixedly connected to the inner front and rear sides of the mechanism seat 691 near the left and right sides. A movable seat 693 is movably sleeved on the outer side of the first limiting rods 692. A spring 695 is movably sleeved on the outer side of both first limiting rods 692, and the spring 695 is located on the rear side of the movable seat 693. An insert plate 694 is rotatably connected to the middle of the outer side of the movable seat 693. Several annularly distributed slots 611 are opened on the outer side of the threaded seat 62. The outer side of the insert plate 694 is movably sleeved on the inner side of the slot 611 located on the rear side near the front side.

[0038] It should be noted that the spring 695 pushes the movable seat 693, causing the insert plate 694 to be inserted into the slot 611, thereby fixing the threaded seat 62. Pushing the insert plate 694 backward causes it to disengage from the slot 611, allowing the slot 611 to rotate.

[0039] like Figure 5 As shown, a torsion spring is provided between the rear side of the insert plate 694 and the outer side of the movable seat 693.

[0040] It should be noted that the torsion spring is used to drive the insertion plate 694 to rotate. When the insertion plate 694 is disengaged from the slot 611, the torsion spring drives the front side of the insertion plate 694 to rotate upward, so as to prevent the insertion plate 694 from returning to the slot 611 due to the influence of the spring 695, and to prevent the insertion plate 694 from affecting the operation when adjusting the threaded seat 62.

[0041] The working principle of this utility model is as follows: First, the upper side of the flexible tube 66 is connected to a storage tank for storing eye patch solution. A solenoid valve 65 controls the opening and closing of the lower side of the flexible tube 66. By rotating the threaded seat 62, the threaded seat 62 drives the screw 63 to move up and down, thereby controlling the height of the piston 64. When the solenoid valve 65 opens, eye patch solution is poured into the storage tube 61. Then, a miniature pump is installed inside the injection head 67 to pour the eye patch solution downwards from the storage tube 61. Since no flow sensor or other components are needed on the lower side of the injection head 67, the injection head 67... The bottom of tube 7 is smooth and flat, facilitating hydrophobic treatment to prevent the retention of small amounts of eye patch solution. The liquid level sensor 612 detects the amount of eye patch solution in the reservoir tube 61. When the eye patch solution contacts the liquid level sensor 612, the sensor also measures the liquid level, causing the solenoid valve 65 to close. The liquid level sensor 612 has multiple through-holes in the piston 64 to prevent a low-pressure state from forming on the inner side of the reservoir tube 61 below the piston 64 when the injection head 67 draws out the eye patch solution. This is achieved by rotating the threaded seat 6. 2. The height of the liquid level sensor 612 is adjusted, allowing it to adjust the volume as needed. Then, the injection head 67 fills the eye patch solution in the reservoir tube 61 downwards, ensuring precise dosage and convenient operation. The active injection method avoids the problem of excessive eye patch dripping. Finally, the spring 695 pushes the movable seat 693, causing the insert plate 694 to insert into the slot 611, fixing the insert plate 694 to the threaded seat 62. Pushing the insert plate 694 backward disengages it from the slot 611, causing the slot 611 to... It can rotate. The torsion spring is used to drive the insertion plate 694 to rotate. When the insertion plate 694 is disengaged from the slot 611, the torsion spring drives the front side of the insertion plate 694 to rotate upward, preventing the insertion plate 694 from returning to the slot 611 due to the influence of the spring 695. This prevents the insertion plate 694 from affecting the operation when adjusting the threaded seat 62. By fixing the insertion plate 694, the threaded seat 62 is prevented from rotating on its own due to vibration during equipment operation. When it is necessary to adjust the threaded seat 62, the insertion plate 694 can be pushed directly to quickly and conveniently fix the threaded seat 62. The operation is convenient and the control is simple.
