Description

Technical Field

[0001] This utility model relates to the field of light stabilizers, and in particular to a sampling device for raw materials used in the production of light stabilizers. Background Technology

[0002] Light stabilizers are additives used in polymer products (such as plastics, rubber, coatings, and synthetic fibers). They can shield or absorb the energy of ultraviolet rays, quench singlet oxygen, and decompose hydrogen peroxide into inactive substances. These functions enable polymers to eliminate or slow down the possibility of photochemical reactions under light radiation, and prevent or delay the photoaging process, thereby extending the service life of polymer products.

[0003] Existing light stabilizer sampling methods involve using a sampler to take samples for testing. However, these devices lack the ability to quantitatively sample light stabilizers, which reduces the quality of light stabilizer testing. To address this issue, we propose a light stabilizer production raw material sampling device. Utility Model Content

[0004] The purpose of this invention is to provide a sampling device for raw materials used in the production of light stabilizers, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sampling device for raw materials used in the production of light stabilizers includes a sampling housing. An L-shaped fixing frame is fixedly connected to the outer surface of the sampling housing. A sliding groove is formed on the inner side wall of the L-shaped fixing frame. A servo motor is fixedly connected to the inner top wall of the L-shaped fixing frame. A rotating lead screw is fixedly connected to the output end of the servo motor. A positioning plate is threadedly connected to the outer surface of the rotating lead screw. A connecting rod is fixedly connected to the bottom surface of the positioning plate. A sealing gasket is fixedly connected to the bottom end of the connecting rod. A threaded opening is formed on the bottom surface of the sampling housing. An external threaded cylinder is provided below the sampling housing. A one-way feed head is fixedly connected to the bottom end of the external threaded cylinder.

[0007] In a further embodiment, an observation window, which is made of tempered glass, is fixedly embedded on the outer surface of the sampling housing.

[0008] In a further embodiment, a protective cover is fixedly connected to the upper surface of the sampling housing, and the protective cover is made of plastic.

[0009] In a further embodiment, a battery is fixedly mounted on the outer surface of the sampling housing, and a start switch is fixedly connected to the outer surface of the sampling housing.

[0010] In a further embodiment, a turntable is fixedly connected to the outer surface of the externally threaded cylinder, and the outer surface of the sealing gasket is in close contact with the inner wall of the sampling housing.

[0011] In a further embodiment, the external threaded cylinder is adapted to the threaded opening, and the outer surface of the positioning plate is slidably connected to the inner wall of the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This device is equipped with a sampling housing, an L-shaped fixing frame, a slide groove, a servo motor, a rotating lead screw, a positioning plate, a connecting rod, and a sealing gasket. The rotation of the servo motor drives the rotating lead screw to rotate. The rotating lead screw is threadedly connected to the positioning plate, and the positioning plate is slidably connected to the slide groove. This allows the connecting rod and the sealing gasket to easily sample the light stabilizer quantitatively, thus improving the accuracy of the sampling.

[0014] 2. This device is equipped with a threaded port, an external threaded cylinder, and a one-way feed head. By using the external threaded cylinder to fit the threaded port, it can quickly install the sampling housing and the one-way feed head, which can prevent the light stabilizer from falling off after sampling.

[0023] Please see Figure 1-4In this utility model, a sampling device for raw materials used in the production of light stabilizers includes a sampling housing 1. An L-shaped fixing frame 2 is fixedly connected to the outer surface of the sampling housing 1. A sliding groove 3 is provided on the inner side wall of the L-shaped fixing frame 2. A servo motor 4 is fixedly connected to the inner top wall of the L-shaped fixing frame 2. A rotating lead screw 5 is fixedly connected to the output end of the servo motor 4. A positioning plate 6 is threadedly connected to the outer surface of the rotating lead screw 5. A connecting rod 7 is fixedly connected to the bottom surface of the positioning plate 6. A sealing gasket 8 is fixedly connected to the bottom end of the connecting rod 7. A threaded opening 9 is provided on the bottom surface of the sampling housing 1. The lower part of the sampling housing 1... An external threaded cylinder 10 is provided, with a one-way feed head 11 fixedly connected to its bottom end. The rotation of the servo motor 4 can drive the rotating screw 5 to rotate. The rotating screw 5 is threadedly connected to the positioning plate 6, and the positioning plate 6 is slidably connected to the slide groove 3. This allows the connecting rod 7 and the sealing gasket 8 to quantitatively sample the light stabilizer, which improves the sampling accuracy. The external threaded cylinder 10 is adapted to the threaded opening 9, which can quickly install the sampling housing 1 and the one-way feed head 11, thus preventing the light stabilizer from falling off after sampling.

[0024] An observation window 13 is fixedly embedded on the outer surface of the sampling housing 1. The observation window 13 is made of tempered glass, which allows for convenient observation of the light stabilizer after sampling. A protective cover 16 is fixedly connected to the upper surface of the sampling housing 1. The protective cover 16 is made of plastic and protects the rotating screw 5 from accidental injury. The outer surface of the protective cover 16 has an opening, which does not affect the movement of the positioning plate 6. A storage battery 15 is fixedly installed on the outer surface of the sampling housing 1, and a start switch 14 is fixedly connected to the outer surface of the sampling housing 1. The storage battery 15 and the start switch 14 facilitate the supply of power to the electrical components and make it easy to start the electrical components.

[0025] The outer surface of the external threaded cylinder 10 is fixedly connected to a turntable 12. The outer surface of the sealing gasket 8 is in close contact with the inner wall of the sampling housing 1. The external threaded cylinder 10 can be easily rotated using the turntable 12. The external threaded cylinder 10 is adapted to the threaded opening 9. The outer surface of the positioning plate 6 is slidably connected to the inner wall of the slide groove 3, which can facilitate the installation of the sampling housing 1 and the single-feed head 11.

[0026] The working principle of this utility model is as follows:

[0027] First, rotate the turntable 12 to connect the external threaded cylinder 10 to the threaded port 9, which can complete the replacement of the single-feed head 11 and connect the electrical components to the power supply. Then, press the external start switch 14 to set the amount of sample to be taken. At the same time, the rotation of the servo motor 4 causes the rotating screw 5 to rotate. Then, with the rotating screw 5 threadedly connected to the positioning plate 6 and the positioning plate 6 slidingly connected to the slide groove 3, the connecting rod 7 can drive the sealing gasket 8 to rise. In addition, the rise of the sealing gasket 8 can generate air pressure inside the sampling housing 1. Then, with the single-feed head 11, the light stabilizer can be sucked into the interior of the sampling housing 1. The above is the complete usage process of this utility model.
