Description

Technical Field

[0001] This utility model belongs to the field of ink sampling technology, specifically relating to a sampler for detecting the colorimetric properties of finished ink. Background Technology

[0002] Ink is an important material used in printing. It displays patterns and text on a substrate through printing. Ink consists of main components and auxiliary components, which are uniformly mixed and repeatedly rolled to form a viscous colloidal fluid. It is composed of binders (resins), pigments, fillers, additives, and solvents, and is used in various printing applications such as books, packaging, architectural decoration, and electronic circuit boards. With the increase in social demand, the variety and output of inks have also expanded and increased accordingly.

[0003] In the prior art, Chinese utility model patent CN212693349U discloses "an ink detection and sampling device", which includes: a shell, a sleeve, and a piston. The shell has a liquid storage chamber and a sleeve chamber inside, with a liquid storage chamber opening between the liquid storage chamber and the sleeve chamber. The sleeve chamber has a liquid inlet on the side away from the liquid storage chamber. The sleeve has a piston chamber inside, and a jacking interface is provided on the side wall of the sleeve. The upper end of the sleeve has a rod hole. The piston includes a piston rod and a piston head. One end of the piston rod is fixedly connected to the upper end of the piston head, and the other end of the piston rod is sleeved in the rod hole and passes through the sleeve. The piston head is sleeved in the piston chamber. It proposes a new technical approach that does not turbid the extracted ink layer, making the detection results more accurate. It does not interfere with the unextracted ink and can extract ink of different volumes as needed. It is suitable for different detection needs, has a simple operating principle, fewer components, and lower manufacturing costs.

[0004] Existing ink colorimetric sampling devices, although able to connect the rotating sleeve to the inlet and push the piston to the bottom of the piston chamber to seal the rotating sleeve and thus achieve ink sampling, require multiple rotations of the sleeve, pulling of the piston, and calibration of the interface position in actual operation. The operation steps are complex and require a high level of operator proficiency. To solve the above problems, this application proposes a finished ink colorimetric sampling device.

[0034] 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.

[0035] Example

[0036] Please see Figures 1-4 This utility model provides the following technical solution: a finished ink colorimetric detection sampler, including a housing 1.

[0037] The box 1 is equipped with a vertically arranged first partition plate 4, which divides the box 1 into a liquid storage chamber on the left and a liquid transfer chamber on the right.

[0038] A sleeve 6 is rotatably installed inside the liquid transfer chamber. A horizontally arranged second partition plate 7 is fixedly connected inside the sleeve 6, which divides the inner cavity of the sleeve 6 into an upper cavity and a lower cavity.

[0039] The interior of the liquid storage chamber is equipped with a third partition plate 15, which divides the inner cavity of the liquid storage chamber into an upper cavity and a lower cavity;

[0040] The circumferential sidewall of the sleeve 6 is provided with an interface 8 corresponding to the positions of the upper cavity and the lower cavity, respectively;

[0041] Two sets of second liquid inlets 5 are provided on the first isolation plate 4 corresponding to the rotation trajectory of the adapter 8, and two sets of first liquid inlets 2 are provided on the outer wall of the box 1 near the liquid transfer chamber corresponding to the initial position of the adapter 8.

[0042] A piston rod 13 is slidably and through the second isolation plate 7. The portion of the piston rod 13 located inside the sleeve 6 has two piston heads and piston bodies 14 fixed at intervals, which are slidably and sealingly engaged with the upper and lower chambers, respectively.

[0043] The housing 1 is provided with a limiting component 100 to limit the rotation angle of the sleeve 6. The limiting component 100 includes:

[0044] Two connecting plates 9 are symmetrically arranged on the outer wall of the sleeve 6, and each of the two connecting plates 9 has a limit hole 10.

[0045] Two mounting plates 101 are fixed to the outer wall of the housing 1, and through holes 102 are provided on both mounting plates 101.

[0046] A slide rod 103 passes through the through hole 102, and a support piece 104 is fixed to the end of the slide rod 103;

[0047] A limiting block 105 is provided on the top of the support piece 104, and the limiting block 105 can be inserted into the interior of the limiting hole 10;

[0048] The return spring 106, sleeved on the slide rod 103, abuts against the support plate 104 and the mounting plate 101 at both ends, and provides a pre-tightening force toward the limiting hole 10. In use, firstly, push the piston rod 13 downward so that the two piston heads and piston bodies 14 close the two adapter ports 8 on the sleeve 6. Then, raise the top of the housing 1 above the surface of the ink to be tested, stop the first inlet 2 at the layer to be sampled, and pull the piston rod 13 upward so that the ink enters the sleeve 6 through the first inlet 2 and the adapter port 8 in sequence. After the ink enters the inside of the sleeve 6, it needs to be transported to the storage tank. At this time, the sleeve 6 is driven to rotate by external force. When the sleeve 6 rotates, it drives the adapter port 8 to rotate. When the adapter port 8 rotates to correspond with the second inlet 5, the piston rod 13 can be pressed down so that the ink in the sleeve 6 can enter the storage tank through the adapter port 8 and the second inlet port 5 to complete the sampling operation.

[0049] When the sleeve 6 rotates to 180 degrees, the limiting block 105 is engaged in the corresponding limiting hole 10 under the action of the return spring 106. At this time, the sleeve 6 can be limited to prevent it from continuing to rotate, thereby ensuring that the adapter 8 can accurately correspond to the second liquid inlet 5 and the first liquid inlet 2. This not only improves the accuracy of sampling, but also effectively simplifies the operation steps and reduces the requirements for the operator's proficiency.

[0050] Preferably, by Figure 3 and Figure 4 As shown, in this embodiment, a pair of mounting plates 101 are each provided with a square hole 107, which communicates with a through hole 102. The outer wall of the slide rod 103 is also provided with a guide rod 108, which passes through the two square holes 107 and has the freedom to move along the height of the square holes 107. Through the cooperation of the guide rod 108 and the square holes 107, the slide rod 103 can be prevented from rotating, thereby improving the stability of the limiting component 100.

[0051] Preferably, by Figure 2 As shown, in this embodiment, the top of the sleeve 6 is provided with multiple operating plates 11; this increases the contact area with the hand, making it easier for the operator to drive the sleeve 6 to rotate, and further improving the practicality of the device.

[0052] Preferably, by Figure 2 and Figure 3As shown, in this embodiment, two polytetrafluoroethylene (PTFE) sealing strips 12 are symmetrically embedded in the inner wall of the transfer chamber. The sealing strips 12 extend axially along the sleeve 6 and maintain an interference fit with the outer wall of the sleeve 6. When the sleeve 6 rotates, it can prevent ink from seeping out from the gap between the sleeve 6 and the transfer chamber, ensuring the cleanliness and accuracy of the sampling process. At the same time, the PTFE material has good wear resistance and corrosion resistance.

[0053] Preferably, by Figure 1 As shown, in this embodiment, a transparent acrylic observation window 3 is embedded in the outer wall of the liquid storage tank. The surface of the observation window 3 is engraved with volume scale lines. The staff can observe the capacity of the ink in the liquid storage tank through the observation window 3 and accurately control the sampling amount through the volume scale lines, thereby improving the sampling accuracy.

[0054] Preferably, by Figure 3 and Figure 4 As shown, in this embodiment, inclined grooves 109 are provided on both sides of the top of the limiting block 105 to cooperate with the connecting plate 9. When the connecting plate 9 is pressed against the inclined grooves 109 on both sides of the top of the limiting block 105, the limiting block 105 can move inward under the guidance of the inclined grooves 109, so that the limiting block 105 can smoothly pass over the connecting plate 9. When the sleeve 6 rotates to the preset position, under the elastic force of the return spring 106, the limiting block 105 will be inserted into another limiting hole 10, thereby limiting the sleeve 6 again and ensuring that the adapter 8 can accurately correspond to the second liquid inlet 5 or the first liquid inlet 2. The entire limiting process is stable and reliable, which further improves the accuracy of sampling and the convenience of operation. In addition, the design of the inclined grooves 109 also allows the limiting block 105 to move smoothly when it is pressed by the connecting plate 9, avoiding obstruction to the rotation of the sleeve 6, thereby ensuring the smooth progress of the sampling process.

[0055] Components not described in detail in this article are existing technologies.

[0056] The working principle and usage process of this utility model are as follows: When in use, firstly, push the piston rod 13 downward so that the two piston heads and piston bodies 14 close the two adapter ports 8 on the sleeve 6. Then, raise the top of the box 1 above the ink liquid surface to be tested, stop the first inlet 2 at the layer to be sampled, and pull the piston rod 13 upward so that the ink enters the sleeve 6 through the first inlet 2 and the adapter port 8 in sequence.

[0057] Using the set limit component 100, the sleeve 6 is driven to rotate 180 degrees by external force. At this time, the limit block 105 is inserted into the corresponding limit hole 10 under the action of the reset spring 106, thus completing one adjustment of the sampling angle.

[0058] During this process, the cooperation between the guide rod 108 and the square hole 107 ensures the stability of the slide rod 103 and the limiting block 105 in the vertical direction, preventing the limiting failure caused by the rotation of the slide rod 103.

[0059] When the sleeve 6 is rotated to the 180-degree position, the adapter 8 corresponds exactly to the second liquid inlet 5. At this time, press the piston rod 13 down again, and the ink will enter the storage chamber through the adapter 8 and the second liquid inlet 5. Since the polytetrafluoroethylene sealing strip 12 embedded in the inner wall of the liquid chamber maintains an interference fit with the outer wall of the sleeve 6, it effectively prevents ink leakage, ensures the accuracy of sampling, and also effectively simplifies the operation steps and reduces the requirements for the operator's proficiency.

[0060] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
