Description

Technical Field

[0001] This utility model relates to the field of filling technology, specifically to a quantitative filling device for hydrogen peroxide. Background Technology

[0002] Hydrogen peroxide solution, commonly known as hydrogen peroxide, is a pale blue viscous liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection, and food disinfection. Generally, hydrogen peroxide needs to be dispensed into smaller containers during use.

[0003] Chinese patent discloses a hydrogen peroxide weighing and dispensing device, publication number CN218142287U. The device includes a base with a movable groove in the middle. Inside the movable groove is a movable seat. Placement covers are evenly spaced on the upper end of the movable seat. Each placement cover has a groove in the middle for mounting a weighing sensor. Each weighing sensor is electrically connected by a wire to a weighing display controller at the front end of the movable seat. A filling rack is fixedly installed at one end of the upper part of the base. By using weighing sensors in conjunction with the weighing display controller, the device effectively weighs the liquid injected into containers placed later inside each placement cover.

[0004] However, the device still has the following drawbacks: during filling, the bottle is first placed inside the placement hood, and the bottle is moved to the right. After filling, the bottle is moved to the left and then removed. This process is complex and slows down the filling efficiency. Therefore, we propose a quantitative filling device for hydrogen peroxide to solve this problem. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative filling device for hydrogen peroxide to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative filling device for hydrogen peroxide, comprising a workbench, wherein a filling device is provided on the workbench, and the filling device includes a power unit;

[0007] The power unit includes a geared motor, a mounting shaft, and a conveying assembly. The outer surface of the bottom end of the mounting shaft is rotatably connected to the top surface of the worktable via a bearing seat. The top surface of the geared motor and the outer surface of the conveying assembly are both fixedly connected to the inner wall of the worktable.

[0008] The workbench is equipped with a filling section;

[0009] The filling unit includes a filling box and a connecting rod. The bottom surface of the filling box is fixedly connected to the top surface of the mounting shaft. A first sealing plate and a second sealing plate are slidably sleeved on the outer surface of the connecting rod. A discharge pipe is fixedly sleeved on the outer surface of the bottom end of the connecting rod.

[0010] A further improvement is that the power unit also includes a washer, a gear ring, a gear, a guardrail, a bracket, and a rotating frame. The outer surface of the output shaft of the geared motor rotates through the inner wall of the workbench via a first bearing and extends to the top of the workbench. The gear is fixedly sleeved on the outer surface of the output shaft of the geared motor. The gear ring and the rotating frame are both fixedly sleeved on the outer surface of the mounting shaft. By setting up the geared motor, gear, gear ring, mounting shaft, and rotating frame, the geared motor is started, driving the rotating frame to transport the filling bottles.

[0011] A further improvement is that the bottom surface of the support and the bottom surface of the washer are both fixedly connected to the top surface of the workbench, and the outer surface of the guardrail is fixedly connected to the outer surface of the support. By setting the washer, it is easy to move the filling bottle up and down.

[0012] A further improvement is that the filling section also includes a threaded sleeve, a temporary storage box, a first elastic pad, a second elastic pad, a squeeze plate, a first stop, a first spring, a second stop, a second spring, and a sealing ring. The top surface of the threaded sleeve is fixedly and continuously connected to the bottom surface of the filling box. The outer surface of the top of the temporary storage box extends into the inside of the threaded sleeve and is threadedly connected to the inner wall of the threaded sleeve. A sealing strip is fixedly connected to the bottom surface of the threaded sleeve. By setting the threaded sleeve, it is convenient to disassemble and clean the inside of the temporary storage box.

[0013] A further improvement is that the outer surfaces of both the first and second elastic pads are fixedly connected to the inner wall of the temporary storage box; the bottom surface of the second stop is fixedly connected to the top surface of the connecting rod; the first stop is fixedly sleeved on the outer surface of the connecting rod; the bottom end of the first spring is fixedly connected to the top surface of the second sealing plate; and the top end of the first spring is fixedly connected to the bottom surface of the first sealing plate. By setting up the first elastic pad, the second elastic pad, the first sealing plate, the second sealing plate, the first spring, the first stop, and the second stop, the elastic force of the second spring pushes the extrusion plate and the discharge pipe downwards, pulling the connecting rod downwards. This causes the second stop to press down on the first sealing plate, separating the first sealing plate from the first elastic pad, allowing hydrogen peroxide to fill the temporary storage box. When the filling bottle is pushed upwards... When the extrusion plate and discharge pipe move, the connecting rod slowly moves upward, the second spring extends, and the first sealing plate first squeezes the first elastic pad. At the same time, the first stop separates from the first sealing plate. Then, the second stop slowly pushes the second sealing plate upward. At this time, the second spring shortens, causing the second sealing plate to separate from the second sealing pad, allowing the hydrogen peroxide inside the temporary storage box to fall into the filling bottle. When the filling bottle falls, the extrusion plate, discharge pipe, connecting rod, first stop and second stop fall, the first spring extends, and the second spring extends first, causing the second sealing plate to squeeze and contact the second sealing pad. Then, the first stop pushes the first sealing plate downward, causing the first sealing plate to separate from the first sealing pad. At this time, the second spring shortens, and the hydrogen peroxide fills the temporary storage box again.

[0014] A further improvement is that the extrusion plate is fixedly sleeved on the outer surface of the discharge pipe, the bottom end of the second spring is fixedly connected to the top surface of the extrusion plate, and the top end of the second spring is fixedly connected to the bottom surface of the temporary storage box. By utilizing the elastic force of the second spring, when the extrusion plate is not in contact with the filling bottle, the second sealing plate and the second sealing gasket are in a compressed state, while the first sealing plate and the first sealing gasket are in a separated state. When the filling bottle presses the sealing plate upward, the second sealing plate and the second sealing gasket are in a separated state, while the first sealing plate and the first sealing gasket are in a compressed state.

[0015] A further improvement is that the outer surface of the sealing ring is fixedly penetrated through the inner wall of the temporary storage box and extends into the interior of the temporary storage box. The inner wall of the sealing ring is squeezed and slidably connected to the outer surface of the discharge pipe. By setting the sealing ring, the sealing performance between the discharge pipe and the temporary storage box is improved.

[0032] A filling section 21 is provided on the workbench 1;

[0033] The filling section 21 includes a filling box 211 and a connecting rod 210. The bottom surface of the filling box 211 is fixedly connected to the top surface of the mounting shaft 222. The outer surface of the connecting rod 210 is slidably fitted with a first sealing plate 215 and a second sealing plate 216. The outer surface of the bottom end of the connecting rod 210 is fixedly fitted with a discharge pipe 219. The filling section 21 also includes a threaded sleeve 212, a temporary storage box 213, a first elastic pad 214, a second elastic pad 217, a squeezing plate 218, a first stop block 201, a first spring 202, a second stop block 203, a second spring 204, and a sealing ring 205.

[0034] The top surface of the threaded sleeve 212 is fixedly and continuously connected to the bottom surface of the filling box 211. The outer surface of the top of the temporary storage box 213 extends into the inside of the threaded sleeve 212 and is threadedly connected to the inner wall of the threaded sleeve 212.

[0038] The bottom end of the first spring 202 is fixedly connected to the top surface of the second sealing plate 216, and the top end of the first spring 202 is fixedly connected to the bottom surface of the first sealing plate 215.

[0039] The bottom end of the second spring 204 is fixedly connected to the top surface of the extrusion plate 218, and the top end of the second spring 204 is fixedly connected to the bottom surface of the temporary storage box 213. By setting up a washer 223, a filling box 211, a threaded sleeve 212, a temporary storage box 213, a first elastic pad 214, a first sealing plate 215, a second sealing plate 216, a second elastic pad 217, an extrusion plate 218, a discharge pipe 219, a connecting rod 210, a first stop block 201, a first spring 202, a second stop block 203, and a second spring 204, when the filling bottle rotates, the pad 223 pushes the filling bottle upwards. When the filling bottle moves upward, it pushes the squeezing plate 218 upward. The first sealing plate 215 first contacts the first elastic pad 214. The second stop 203 pushes the second sealing plate 216 upward, causing the hydrogen peroxide inside the temporary storage box 213 to fall into the filling bottle. When the filling bottle falls, the second spring 204 extends, and the bottom surface of the second sealing plate 216 first squeezes and contacts the second elastic pad 217.

[0041] The top surface of the filling bottle pushes the extrusion plate 218 upward, which in turn moves the discharge pipe 219, connecting rod 210, first stop 203, and second stop 201 upward. At this time, the second spring 202 extends, causing the first sealing plate 215 to squeeze the first elastic pad 214. Immediately afterwards, the first stop 203 separates from the first sealing plate 215 upward. Subsequently, the second stop 201 pushes the second sealing plate 216 upward, at which point the second spring 202 is compressed, causing the second sealing plate 216 to separate from the second sealing pad 217, allowing the hydrogen peroxide inside the temporary storage box 213 to fall into the filling bottle. As the filling bottle falls along the top surface of the gasket 223... The first spring 204 pushes the extrusion plate 218, discharge pipe 219, connecting rod 210, first stop 203 and second stop 201 down. The second spring 202 first extends, causing the second sealing plate 216 to press down and contact the second sealing gasket 217. Then the second stop 201 separates from the second sealing plate 216. Subsequently, the first stop 203 pushes the first sealing plate 215 down, causing the first sealing plate 215 to separate from the first sealing gasket 214. At this time, the second spring 202 shortens, and hydrogen peroxide fills the interior of the temporary storage tank 213 again. Then the filling bottle is moved to the left conveying assembly 229 and moves forward along the outer surface of the left conveying assembly 229.
