Description

Technical Field

[0001] This utility model relates to the field of polyurethane testing technology, and in particular to a floating sampling mechanism for polyurethane coatings. Background Technology

[0002] In the production process of polyurethane coatings, in order to ensure product quality, it is necessary to take samples on-site and then send them to the laboratory for testing.

[0003] Because sampling devices are usually quite short, such as when using a syringe to sample water-based polyurethane coatings, they can typically only extract the surface of the water-based polyurethane coating. The sampling depth is limited, and the test results cannot fully reflect the quality of the product, so improvements are needed. Utility Model Content

[0004] The purpose of this invention is to provide a floating sampling mechanism for polyurethane coatings, which can sample polyurethane coatings at a certain depth and improve the ease of operation.

[0005] To achieve this objective, the present invention adopts the following technical solution: A floating sampling mechanism for polyurethane coatings includes: a float, a mounting plate, a guide tube, a sampling column, and a lifting rod. The mounting plate is horizontally disposed on top of the float, and the float has a through hole located below the mounting plate. The guide tube is vertically disposed on the mounting plate, and its lower part extends downward through the through hole. The sampling column is vertically disposed in the guide tube. The lifting rod is disposed on top of the sampling column and extends upward. A sampling hole is disposed on the lower part of one side of the guide tube, and a sampling groove is recessed on the side of the sampling column facing the sampling hole.

[0006] The float is made of foamed plastic or hollow plastic.

[0007] The mounting plate is provided with a guide sleeve corresponding to the guide tube.

[0008] The guide tube is concentrically arranged in the guide sleeve, and a first screw pointing to the guide tube is provided on one side of the guide sleeve.

[0009] The mounting plate is provided with a second screw that connects to the float.

[0010] The top of the boom is equipped with a pull ring located above the guide tube.

[0011] The guide tube has a sample outlet located directly above the sampling hole on one side of its upper part.

[0012] The sampling column has annular grooves located above and below the sampling slot on its outer circumference, and a sealing ring is provided in the annular grooves.

[0013] The beneficial effects of this utility model are as follows: A floating sampling mechanism for polyurethane coatings allows a float to float on the polyurethane coating, enabling a guide tube to penetrate into the polyurethane coating below. A sampling column is driven to move downward in the guide tube by a boom. When the sampling hole coincides with the sampling groove, a certain depth of polyurethane coating can be introduced into the sampling groove. Then, the boom is pulled up, and the sampled polyurethane coating flows out through the sampling hole. The operation is simple, and the height of the guide tube can be adjusted, making it widely applicable. Attached Figure Description

[0014] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A schematic diagram of the structure after the sampling column rises. Detailed Implementation

[0015] The following is combined Figures 1-2 The technical solution of this utility model will be further illustrated through specific embodiments.

[0016] like Figure 1 The floating sampling mechanism for polyurethane coating shown includes: a float 1, a mounting plate 4, a guide tube 2, a sampling column 3, and a lifting rod 10. The float 1 is made of foamed plastic block or hollow plastic block, which has high buoyancy and can float on the polyurethane coating, and can move flexibly.

[0017] The mounting plate 4 is horizontally positioned on top of the float 1. In this embodiment, the mounting plate 4 is provided with a second screw 8 connected to the float 1, resulting in a stable structure and convenient assembly and disassembly. The float 1 is provided with a through hole 11 located below the mounting plate 4. The guide tube 2 is vertically positioned on the mounting plate 4, and the lower part of the guide tube 2 extends downward through the through hole 11, allowing it to penetrate into the polyurethane coating below.

[0018] To sample polyurethane coatings at different depths, the guide tube 2 needs to be raised and lowered. In this embodiment, the mounting plate 4 is provided with a guide sleeve 5 corresponding to the guide tube 2. The guide sleeve 5 can be welded to the mounting plate 4, resulting in a stable structure.

[0019] The guide tube 2 is concentrically arranged in the guide sleeve 5, and the guide sleeve 5 guides the guide tube 2 to move up and down. A first screw 6 is provided on one side of the guide sleeve 5, pointing towards the guide tube 2. The first screw 6 is used to tighten the guide tube 2 after the up and down adjustment to prevent it from loosening. The guide tube 2 is made of stainless steel, which is corrosion resistant and easy to clean.

[0020] The sampling column 3 is vertically and flexibly installed in the guide tube 2. The lifting rod 10 is installed on the top of the sampling column 3 and extends upward. In this embodiment, the top of the lifting rod 10 is provided with a pull ring 7 located above the guide tube 2, which facilitates the pushing and pulling of the lifting rod 10 and realizes the lifting and lowering control of the sampling column 3.

[0021] like Figure 1 As shown, a sampling hole 14 is provided on the lower part of one side of the guide tube 2, and a sampling groove 12 is recessed on the side of the sampling column 3 facing the sampling hole 14. The float 1 floats on the polyurethane coating, causing the guide tube 2 to penetrate into the polyurethane coating below. The sampling column 3 is driven to move down in the guide tube 2 by the suspension rod 10. When the sampling hole 14 coincides with the sampling groove 12, a certain depth of polyurethane coating can be introduced into the sampling groove 12 to achieve sampling of polyurethane coating at a certain depth.

[0022] A sample outlet 9 is provided on the upper part of one side of the guide tube 2, located directly above the sampling hole 14, such as... Figure 2 As shown, when the height of the sample outlet 9 and the sampling slot 12 coincide, the sampled polyurethane coating flows out through the sample outlet 9. It can be transferred using a container, making the operation simple.

[0023] To ensure sampling accuracy, an annular groove is provided on the outer circle of the sampling column 3, located above and below the sampling groove 12. A sealing ring 13 is provided in the annular groove, which has good sealing performance and prevents the polyurethane coating in the guide tube 2 from entering the sampling groove 12.

[0024] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
