Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing and sampling technology, specifically a sampling device for finished product testing. Background Technology
[0002] The sampling device for UV coating finished product testing is used to remove the UV coating finished product from the storage tank, making it convenient to sample and test the UV coating finished product. The main function of the reactive diluent is to dissolve the solid components in the UV coating and adjust the viscosity of the system. The diluent in UV coating is not the volatile organic solvent used in general coatings, but a non-volatile solvent that directly participates in the curing and film-forming process and has the ability to react. At present, UV coating sampling requires hand-held sampling tubes to be used. By inserting the sampling tube into the UV coating at different depths, samples are taken from the upper, middle and lower layers of the UV coating.
[0003] When using manual handheld sampling, the sampling tube may contain residual UV coating from other depths when sampling UV coating at different depths. This can affect the accuracy of subsequent sampling of UV coating at other depths, impacting the test results and making it inconvenient to sample UV coating at different depths simultaneously. Utility Model Content
[0004] The purpose of this invention is to provide a sampling device for finished product testing, 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 finished product testing, comprising:
[0007] A fixing frame is fixedly installed on the upper surface of the fixing frame, and multiple No. 1 connecting tubes are fixedly installed inside the fixing frame. Multiple sampling bottles are detachably connected to one end of each No. 1 connecting tube.
[0008] A sampling assembly is connected to the other end of a first connecting pipe. The sampling assembly includes a sampling tube. Multiple air inlet pipes are fixedly embedded at different heights on the outer surface of the sampling tube, and multiple discharge pipes are fixedly embedded at different heights on the outer surface of the sampling tube.
[0009] The suction assembly is fixedly installed on the upper surface of the fixed frame.
[0010] Furthermore, multiple feed pipes are fixedly embedded at the same height as the connection between the outer surface of the sampling tube and the discharge pipe.
[0011] Preferably, a one-way valve is fixedly installed inside both the feed pipe and the discharge pipe, and a baffle is fixedly installed inside the sampling pipe above the air inlet pipe.
[0012] Furthermore, the suction assembly includes:
[0013] The negative pressure chamber is fixedly installed on the upper surface of the fixed frame;
[0014] Multiple piston plates are slidably connected to multiple cavities inside the negative pressure chamber;
[0015] The T-shaped rod is rotatably connected to the upper surface of the piston plate and passes through the negative pressure chamber.
[0016] Preferably, a handle is fixedly connected between the negative pressure chamber and the fixed frame. Multiple No. 2 connecting pipes are fixedly installed on one side surface of the fixed frame. Connecting sleeves are fixedly installed at the other end of the No. 1 connecting pipe and the No. 2 connecting pipe. The air inlet pipe and the discharge pipe are respectively movably inserted into the connecting sleeves at the corresponding positions. The No. 2 connecting pipe is fixedly connected to the negative pressure chamber.
[0017] Preferably, a support frame is fixedly installed on the upper surface and both sides of the negative pressure chamber. A turntable is rotatably connected inside the support frame. Multiple adjustment holes are equidistantly opened on one side surface of the turntable. A motor is fixedly installed on one side surface of the support frame, and the output end of the motor is fixedly connected to a turntable.
[0018] Preferably, the T-shaped rod has T-shaped grooves at both ends, and a plug rod is movably inserted into the T-shaped groove. A spring is fixedly connected between the plug rod and the T-shaped groove, and the plug rod passes through the T-shaped groove and is movably inserted into the adjustment hole at the corresponding position.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] 1. The motor drives the turntable to rotate the T-shaped rod, which in turn moves the piston plate up and down. This continuously generates suction and thrust inside the air inlet pipe. When suction is generated inside the air inlet pipe, the one-way valve inside the feed pipe opens, allowing the UV coating to enter the sampling pipe. When thrust is generated at the air inlet pipe, the one-way valve inside the feed pipe closes, and the one-way valve inside the discharge pipe opens, allowing the UV coating to enter the discharge pipe. The UV coating is then pumped into the sampling bottle. In this negative pressure environment created by the suction assembly, UV coating at different depths is extracted simultaneously through multiple feed pipes. This replaces manual sampling of UV coating at different depths sequentially, preventing residual UV coating at other depths from affecting the accuracy of subsequent UV coating sampling and reducing the impact on subsequent test results.
[0021] 2. Slide the insert rod into the T-slot to separate it from the adjustment hole at that location. Move the height of the piston plate and move the insert rod to another adjustment hole at a different height. This causes the piston plate to move up and down as the turntable rotates, resulting in different suction and thrust forces generated inside the air intake pipe at different heights. This ensures that the amount of UV coating extracted from different depths is roughly the same. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figure 1-6In this embodiment of the present invention, a sampling device for finished product testing includes a fixed frame 1, a fixed frame 101 fixedly installed on the upper surface of the fixed frame 1, a plurality of first connecting pipes 102 fixedly installed inside the fixed frame 101, a plurality of sampling bottles 105 detachably connected to one end of each first connecting pipe 102, a sampling component 2 connected to the other end of the first connecting pipe 102, the sampling component 2 including a sampling tube 201, a plurality of air inlet pipes 205 fixedly embedded at different heights on the outer surface of the sampling tube 201, a plurality of discharge pipes 204 fixedly embedded at different heights on the outer surface of the sampling tube 201, and a suction component 3 fixedly installed on the upper surface of the fixed frame 101.
[0031] Specifically, the sampling tube 201 is inserted into the UV coating, and the suction component 3 provides the power to extract the UV coating, extracting the upper, middle and lower layers of UV coating into multiple sampling bottles 105 respectively.
[0032] Example 1
[0033] like Figure 1-4 As shown, in this embodiment, multiple feed pipes 202 are fixedly embedded at the same height as the discharge pipe 204 on the outer surface of the sampling tube 201; one-way valves 206 are fixedly installed inside both the feed pipe 202 and the discharge pipe 204; a partition 203 is fixedly installed inside the sampling tube 201 above the air inlet pipe 205; a handle 106 is fixedly connected between the negative pressure chamber 301 and the fixed frame 101; multiple second connecting pipes 103 are fixedly installed on one side surface of the fixed frame 101; a connecting sleeve 104 is fixedly installed at the other end of the first connecting pipe 102 and the second connecting pipe 103; the air inlet pipe 205 and the discharge pipe 204 are movably inserted into the connecting sleeve 104 at the corresponding positions; and the second connecting pipe 103 is fixedly connected to the negative pressure chamber 301.
[0034] In this embodiment, the sampling component 2 can be quickly disassembled and installed via the connecting sleeve 104. Different lengths of sampling tubes 201 can be used to sample UV coatings at different depths. Suction is generated inside the air inlet pipe 205, opening the one-way valve 206 inside the feed pipe 202, allowing the UV coating to enter the sampling tube 201 from the feed pipe 202. A thrust is generated at the air inlet pipe 205, closing the one-way valve 206 inside the feed pipe 202, and opening the one-way valve 206 inside the discharge pipe 204, allowing the UV coating to enter the discharge pipe 205. Inside the sample bottle 105, the UV coating is pumped into the sample bottle 105. The suction component 3 is then secured above the UV coating container by the fixing frame 1. The sampling component 2 is inserted into the UV coating. Under the negative pressure created by the suction component 3, UV coating at different depths is extracted simultaneously through multiple feed tubes 202. This replaces manual sampling of UV coating at different depths in sequence, preventing residual UV coating at other depths from affecting the accuracy of subsequent UV coating sampling and reducing the impact on subsequent test results.
[0035] like Figure 4-6 As shown, in this embodiment, the suction assembly 3 includes: a negative pressure chamber 301 fixedly installed on the upper surface of the fixed frame 101; multiple piston plates 302 slidably connected to multiple cavities inside the negative pressure chamber 301; a T-shaped rod 303 rotatably connected to the upper surface of the piston plates 302 and penetrating through the negative pressure chamber 301; a support frame 306 is fixedly installed on the upper surface and both sides of the negative pressure chamber 301; a turntable 307 is rotatably connected inside the support frame 306; multiple adjustment holes 308 are equidistantly opened on one side surface of the turntable 307; a motor 4 is fixedly installed on one side surface of a support frame 306; and the output end of the motor 4 is fixedly connected to a turntable 307.
[0036] In practice, the motor 4 operates, driving multiple turntables 307 to rotate. These turntables are connected to the adjustment hole 308 via the insertion rod 304, and then to the piston plate 302 via the T-shaped rod 303. Under the sliding limit action of the piston plate 302 and the negative pressure chamber 301, the turntables 307 drive the T-shaped rod 303 to rotate, causing the piston plate 302 to move up and down. This continuously generates suction and thrust inside the air inlet pipe 205, providing power for the extraction of UV coating.
[0037] Example 2
[0038] Based on Example 1, in order to compensate for the problem that the suction generated inside multiple air inlets 205 is the same, resulting in a large difference in the amount of UV coating extracted at different depths.
[0039] like Figure 5 and Figure 6As shown, in this embodiment, T-shaped grooves 305 are provided at both ends of the T-shaped rod 303. A rod 304 is movably inserted into the T-shaped groove 305. A spring 309 is fixedly connected between the rod 304 and the T-shaped groove 305. The rod 304 passes through the T-shaped groove 305 and is movably inserted into the adjustment hole 308 at the corresponding position.
[0040] In practice, the insert rod 304 is slid into the T-slot 305 to separate it from the adjustment hole 308. The height of the piston plate 302 is moved to move the insert rod 304 to another adjustment hole 308 at a different height. The spring 309 pushes the insert rod 304 out and inserts it into the adjustment hole 308 at that height. This causes the piston plate 302 to move up and down as the turntable 307 rotates, resulting in different suction and thrust forces generated inside the air inlet pipe 205 at different heights. This makes it easier to ensure that the amount of UV coating extracted from different depths is roughly the same.
[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0042] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
