Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin production, in particular to a quality detection device for a sanitary napkin production line. Background Art

[0002] With the passage of time, sanitary napkins have gradually become common daily necessities in people's lives. During the production of sanitary napkins, it is necessary to detect the quality of sanitary napkins to maintain the quality of sanitary napkin products.

[0003] For example, a quality detection device for a sanitary napkin production line with the patent number CN218865870U includes a main body. One side of the main body is fixedly connected to a workbench, and sanitary napkins are placed on the top of the workbench. A uniform detection device is arranged on the main body. The uniform detection device includes a motor. When in use, by setting the uniform detection device, the water pump and the motor are started, the water pump extracts the water flow along the inner wall of the storage tank through the extraction pipe, and the water flow is transmitted to the nozzle, so that the water flow accurately falls on the center position of the sanitary napkin through the funnel A, achieving the effect of detecting the water absorption quality of the sanitary napkin. And by starting the motor, the moving block drives the nozzle to move, so that the nozzle evenly sprays the sanitary napkins on the workbench, making the water absorption detection effect of each group of sanitary napkins the same. However, the excess water in the above document directly enters the water tank for recycling. If impurities are mixed in the water, it is easy to damage the water pump during water circulation. At the same time, the lower part of the sanitary napkin is solidly set when spraying water on the sanitary napkin, and it is easy to have accumulated water at the position where the lower part of the sanitary napkin contacts the solid plate. The water cannot directly fall when the sanitary napkin absorbs water to saturation, thus affecting the quality detection of the sanitary napkin. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that impurities mixed in the water are easy to damage the water pump during water circulation, and a quality detection device for a sanitary napkin production line is proposed.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design a quality detection device for a sanitary napkin production line, including a base and a bracket. The bracket is fixedly connected to the upper surface of the base. A water tank is fixedly connected to the upper surface of the base. A frame is fixedly connected to the upper surface of the water tank. An anti-pooling mechanism is arranged inside the frame. The water tank is fixedly connected to the outer wall of the hopper. A filtering mechanism is arranged inside the hopper. The frame is fixedly connected to the outer walls of the first funnel and the second funnel.

[0007] Preferably, the filtering mechanism includes a cross bar fixedly connected inside the hopper. A sliding rod is slidably connected inside the cross bar. A disc is fixedly connected to the lower end of the sliding rod. A sphere is fixedly connected to the upper end of the sliding rod. A spring is sleeved on the outer wall of the sliding rod, and both ends of the spring are fixedly connected to the sliding rod and the cross bar respectively. A first filter screen is attached above the sphere, and the outer wall of the first filter screen is fixedly connected to the frame.

[0008] Preferably, the water accumulation prevention mechanism includes a cross plate fixedly connected to the inner wall of the frame. A through hole is provided inside the cross plate. Two fixing blocks are fixedly connected to the inner wall of the through hole. A second filter screen is attached above the two fixing blocks, and the outer wall of the second filter screen fits with the through hole.

[0009] Preferably, the water tank is communicated with the input end of the water pump. The water pump is fixedly connected to the upper surface of the base. A pipeline is fixedly connected to the output end of the water pump.

[0010] Preferably, a spray head is fixedly connected to the end of the pipeline. The spray head is fixedly connected to the surface of the moving mechanism, and the moving mechanism is arranged inside the bracket.

[0011] Preferably, a sanitary napkin is arranged inside the through hole.

[0012] A quality inspection device for a sanitary napkin production line proposed by the present utility model has the beneficial effects that: through the cooperation among the cross bar, the sliding rod, the disc, the sphere, the spring and the first filter screen, the first filter screen filters the water entering the hopper. When the water passes through the first filter screen, it impacts the disc. The disc drives the sliding rod to slide, and the sliding rod compresses the spring. When the spring is compressed to the limit position, it drives the sliding rod to move in the reverse direction. The sliding rod drives the sphere to move, and the sphere knocks on the first filter screen to prevent the first filter screen from being blocked, enabling the first filter screen to filter the water entering the water tank through the hopper, avoiding damage to the water pump caused by impurities in the water during water circulation. The water returning to the water tank continues to enter the pipeline for recycling.

[0013] Through the cooperation among the cross plate, the through hole, the fixing blocks and the second filter screen, the second filter screen is placed inside the through hole, and the second filter screen fits with the two fixing blocks. The two fixing blocks play a role in limiting and supporting the second filter screen. The sanitary napkin to be subjected to quality inspection is placed inside the through hole and contacts the second filter screen. When the sanitary napkin is saturated with water, it will no longer absorb water, and the excess water falls through the second filter screen. The quality of the sanitary napkin is judged by the water absorption rate of the sanitary napkin. There will be no water accumulation at the position where the lower part of the sanitary napkin contacts the second filter screen, enabling the water to directly fall when the sanitary napkin reaches the saturated water absorption state, and thus not affecting the quality inspection of the sanitary napkin.
