Description

Technical Field

[0001] The invention relates to the technical field of ink resin production, in particular to a sampling device for producing water-based polyurethane ink resin. Background Art

[0002] Water-based polyurethane ink resin is a polyurethane resin system with water as the dispersion medium. It is mainly used for the preparation of printing inks. Compared with traditional solvent-based polyurethane inks, it has the characteristics of low volatile organic compounds, environmental protection, and safety.

[0003] Due to the intense friction between the blades and the resin and the eddy current movement inside the resin during the production and mixing process of the water-based polyurethane ink resin, air is easily drawn into the resin to form bubbles. When a sampler is used to sample the water-based polyurethane ink resin during the stirring process, the sample resin taken out contains a large number of bubbles. The existing sampler cannot eliminate the bubbles in the sample resin, resulting in the sample resin being occupied by bubbles. The actual capacity of the sample resin taken out is less than the standard capacity. When the density of the sample resin is measured, because the space of the sample resin is occupied by bubbles, under the condition of the same volume, the density of the sample resin is lower than the standard density, resulting in errors in the density measurement value of the water-based polyurethane ink resin. Summary of the invention

[0039] The housing 1 is provided with a window 1002 .

[0040] The housing 1 also includes a magnet 6 ; the magnet 6 is fixedly connected to the inside of the housing 1 .

[0041] The present invention uses the vacuum hood 5 to evacuate the sample resin in the housing 1, so that a negative pressure is formed in the housing 1, and then the bubbles in the sample resin are extracted from the resin, thereby solving the problem that the bubbles occupy the sample resin space, the actual volume of the sample resin taken out is reduced, and the error in the subsequent density measurement is caused. The specific process is as follows:

[0042] Before sampling and testing the water-based polyurethane ink resin in the reactor, in the initial state, Figure 2As shown, the push plate 102 and the extrusion plate 103 are both located in the reactor. When sampling the resin, the staff first pulls the pull rod 101 to the right to drive the push plate 102 and the extrusion plate 103 to move into the shell 1. During this process, the resin in the reactor enters the shell 1 together with the movement of the push plate 102 and the extrusion plate 103. At this time, the sample to be taken out is located between the push plate 102 and the extrusion plate 103. When the pull rod 101 drives the push plate 102 to move to the first insertion rod 106, the staff inserts the first insertion rod 106 into the locking hole 10201 to fix the push plate 102. At this time, the extrusion plate 103 drives the blocking plate 3 to move to the lower side of the transmission tube 5001 to block the transmission tube 5001 to prevent the resin between the push plate 102 and the extrusion plate 103 from entering the transmission tube 5001. Taking the view from right to left as the reference, the staff then turns the pull rod 101 clockwise, The locking part 10101 and the locking part 10102 are driven to rotate clockwise, so that the locking part 10101 is disengaged from the sliding groove 10401, and the restriction of the pull rod 101 on the push plate 102 is released. At this time, the protrusion 10103 passes through the avoidance groove 1003 and contacts the vacuum hood 5. Then the staff continues to pull the pull rod 101 to the right, driving the extrusion plate 103 to move continuously to the right, and at the same time pushing the vacuum hood 5 to move to the right, so that the volume of the air cavity 5002 increases and a negative pressure is generated, and at the same time the space between the push plate 102 and the extrusion plate 103 is increased. The resin liquid level between the push plate 102 and the extrusion plate 103 decreases as the space increases. Since the resin is not easily compressed relative to the gas, the volume of the bubbles in the resin expands, and the gas occupies the space above the resin liquid level. In this process, the bubbles in the sample resin are continuously precipitated and accumulated in the upper area of ​​the resin liquid level, reducing the bubble content in the sample resin.

[0043] When the vacuum hood 5 moves to the right, the vacuum hood 5 drives the knocking hammer 301 to pass through each protrusion 302 one by one. When passing through the protrusion 302, the knocking hammer 301 knocks on the outer side of the shell 1 under the elastic force of the torsion spring, causing the shell 1 to vibrate, which is beneficial to accelerate the efficiency of the flotation of bubbles in the sample resin and enhance the effect of eliminating bubbles in the resin.

[0044] As the pull rod 101 drives the extrusion plate 103 and the exhaust hood 5 to continue to move to the right, when the sealing plate 3 passes through the transmission tube 5001 as the extrusion plate 103 moves, since the increase in the air cavity 5002 is greater than the increase in the space between the push plate 102 and the extrusion plate 103, when the space between the push plate 102 and the extrusion plate 103 is connected to the air cavity 5002 through the transmission tube 5001, the gas on the upper side of the resin liquid surface between the push plate 102 and the extrusion plate 103 is sucked into the air cavity 5002. At this time, the extrusion plate 103 moves to the second insertion rod 107, and the staff inserts the second insertion rod 107 into the locking port 10301 to fix the extrusion plate 103. At this time, the sealing plate 3 contacts and is adsorbed by the magnet 6. Taking the view from right to left as the reference, the staff then Rotate the pull rod 101 clockwise again, driving the locking part 10102 to rotate clockwise, so that the locking part 10102 disengages from the movable groove 10501, and releases the restriction of the pull rod 101 on the extrusion plate 103. Then the staff continues to pull the pull rod 101 to the right, driving the vacuum hood 5 to move continuously to the right, so that the air cavity 5002 is further enlarged to generate negative pressure, and the upper side of the resin liquid surface between the push plate 102 and the extrusion plate 103 is sucked, which is beneficial to enhance the precipitation effect of bubbles in the resin between the push plate 102 and the extrusion plate 103, further reduce the bubble content in the sample resin, prevent the actual volume of the sample resin taken out of the sampling bottle from being reduced, avoid errors in the subsequent density measurement of the resin, and improve the accuracy of the detected values ​​of the water-based polyurethane ink resin.

[0045] When the liquid level in the sample resin drops, the staff can observe the drop of the liquid level of the sample resin in the shell 1 through the window 1002 to judge the sampling time. When the bubbles in the sample resin are precipitated, the staff connects the sampling bottle to the sample discharge port 1001, and then transmits nitrogen from the air pipe 5003 to the air cavity 5002 through the external air source, replenishes nitrogen into the negative pressure air cavity 5002, relieves the negative pressure in the air cavity 5002, and allows the nitrogen in the air cavity 5002 to enter the upper side of the resin liquid level between the push plate 102 and the extrusion plate 103 through the air pipe 5003, relieves the negative pressure between the push plate 102 and the extrusion plate 103. At this time, the staff opens the valve 2 to allow the sample resin in the shell 1 to flow into the sampling bottle through the sample discharge port 1001. Then the staff pushes the pull rod 101 to the left, driving the stopper 10102 to fit the extrusion plate 103. On the right side, based on the view from right to left, the staff then rotates the pull rod 101 counterclockwise to make the locking portion 10102 fit into the movable groove 10501, and removes the second plug rod 107 from the locking port 10301, releasing the fixation of the extrusion plate 103, so that the pull rod 101 pushes the extrusion plate 103 and the second rubber pad 202 toward the push plate 102, and squeezes the sample resin between the push plate 102 and the extrusion plate 103 into the sampling bottle through the sample discharge port 1001. In this process, nitrogen is transmitted from the air cavity 5002 to the space between the push plate 102 and the extrusion plate 103 to pressurize the space between the push plate 102 and the extrusion plate 103, which is beneficial to accelerate the discharge of the sample resin and prevent the sample resin from being squeezed into the transmission tube 5001, preventing the transmission tube 5001 from being blocked by resin, and avoiding the reduction of the bubble elimination effect on the sample resin during the next sampling.

[0046] When the extrusion plate 103 drives the second rubber pad 202 to move toward the push plate 102, the blocking plate 3 is adsorbed by the magnet 6, so that the blocking plate 3 cannot move toward the push plate 102 together with the extrusion plate 103, and at the same time, the first elastic member 4 is stretched to prevent the transmission tube 5001 from being blocked by the blocking plate 3 too early and the nitrogen cannot fully enter between the push plate 102 and the extrusion plate 103. While accelerating the discharge of the sample resin, the cleaning effect of the residual resin in the transmission tube 5001 is guaranteed. As the extrusion plate 103 continues to move toward the push plate 102, the first elastic member 4 is continuously stretched. When the elastic force of the first elastic member 4 after being stretched is greater than the adsorption force of the magnet 6 on the blocking plate 3, the blocking plate 3 is reset under the elastic force of the first elastic member 4, and the transmission tube 5001 is re-blocked.

[0047] When the extrusion plate 103 continues to move toward the push plate 102, so that the locking part 10101 contacts the locking rod 104, the staff rotates the pull rod 101 counterclockwise again, so that the locking part 10101 is stuck in the sliding groove 10401, and then the staff continues to push the pull rod 101, so that the locking part 10101 passes over the locking rod 104, driving the extrusion plate 103 to continue to approach the push plate 102. When the first rubber pad 201 and the second rubber pad 202 contact, since the inclination of the inclined surface of the first rubber pad 201 is greater than the inclination of the inclined surface of the second rubber pad 202, an angle with an opening downward is formed between the first rubber pad 201 and the second rubber pad 202, which is conducive to gradually squeezing the resin between the first rubber pad 201 and the second rubber pad 202 downward, preventing the resin from being sandwiched between the first rubber pad 201 and the second rubber pad 202 and unable to be discharged normally, thereby enhancing the resin discharge effect.

[0048] When the sampling is completed, the staff removes the sampling bottle from the sampling port 1001, then pulls the pull rod 101 to the right, so that the locking part 10101 re-enters the sliding groove 10401, and then the staff turns the pull rod 101 clockwise to make the locking part 10101 stuck between the two locking rods 104, and at the same time takes the first plug rod 106 out of the locking hole 10201 to release the fixation of the push plate 102. Then the staff connects the external exhaust device to the sampling port 1001, and sucks the nitrogen remaining between the first rubber pad 201 and the second rubber pad 202 in the shell 1 to prevent the nitrogen from entering the reactor with the reset of the push plate 102 and the extrusion plate 103, so as to avoid the increase of bubbles in the resin in the reactor. Then the staff closes the valve 2 and pushes the pull rod 101 to the left, driving the push plate 102, the extrusion plate 103 and other related components to move to the left together. Figure 2 As shown, the push plate 102, the extrusion plate 103 and other related components are put back into the reactor to prepare for the next sampling work.

[0049] Example 2

[0050] On the basis of Example 1, Figure 2-Figure 9 As shown, it also includes an adjustment system, which includes a movable rod 401, a second elastic member 402, a locking block 403 and a multi-stage telescopic rod 404; the movable rod 401 is slidably connected to the pull rod 101; the second elastic member 402 is fixedly connected to the movable rod 401, and the second elastic member 402 is a spring; the second elastic member 402 is fixedly connected to the pull rod 101; the locking block 403 is slidably connected to the pull rod 101; a recess 20101 is provided on the first rubber pad 201; the locking block 403 slides in the recess 20101; the multi-stage telescopic rod 404 is fixedly connected to the shell 1; the telescopic end of the multi-stage telescopic rod 404 is fixedly connected to the right side of the extrusion plate 103.

[0051] When the resin in the reactor is stirred counterclockwise, the staff releases the movable rod 401 and the movable rod 401 moves to the left under the elastic force of the second elastic member 402, and pushes the locking block 403 upward, so that the locking block 403 is stuck in the recess 20101, thereby limiting the position of the first rubber pad 201 by the pull rod 101. When the staff sees from right to left, they then rotate the pull rod 101 clockwise, so that the pull rod 101 drives the first rubber pad 201 to rotate 90° clockwise, while the second rubber pad 202 and the extrusion plate 103 are restricted by the multi-stage telescopic rod 404 and will not rotate with the pull rod 101. When looking from a bird's-eye view, the first rubber pad 201 and the second rubber pad 202 are as follows: Fig. 9 As shown in the shrinking shape, when the resin passes between the first rubber pad 201 and the second rubber pad 202, the flow speed of the resin is accelerated, and the flushing force on the position of the reactor sampling tube is enhanced, so as to prevent the resin raw materials from accumulating at the position of the reactor sampling tube and failing to be fully mixed, and to prevent the resin taken out from the sampling tube from containing the resin raw materials that are not fully reacted, thereby avoiding errors in the detection of the sample resin and ensuring the accuracy of the sample resin detection data. In the process of the pull rod 101 driving the first rubber pad 201 to rotate clockwise, the locking block 403 is stuck in the recess 20101 to lock the first rubber pad 201. The first rubber pad 201 is limited so that it cannot slide relative to the pull rod 101 in the left-right direction, that is, the push plate 102 and the locking rod 104 will not be relatively displaced with the pull rod 101 in the left-right direction. Even if the pull rod 101 is rotated to disengage the locking portion 10101 from the sliding groove 10401, the locking portion 10101 can be re-engaged in the sliding groove 10401 by rotating the pull rod 101. Similarly, the locking portion 10102 that has disengaged from the movable groove 10501 can be re-engaged in the movable groove 10501 by rotating the pull rod 101, so that the pull rod 101 can limit the extrusion plate 103.

[0052] When sampling the water-based polyurethane ink resin, when the staff pulls the pull rod 101 to the right, the staff pulls the movable rod 401 to the right on the pull rod 101 and stretches the second elastic member 402 at the same time, thereby releasing the squeezing of the locking block 403 by the movable rod 401, causing the locking block 403 to fall from the recess 20101, thereby releasing the lock of the pull rod 101 on the first rubber pad 201, and preventing the first rubber pad 201 from rotating together when the pull rod 101 is rotated subsequently.

[0053] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
