[0002] Food contact inks refer to inks intended for printing on food contact materials and products, directly or indirectly contacting food. Their components may migrate into food; therefore, physicochemical indicators such as heavy metal residue and migration levels are specified, and migration tests are required to ensure safety. Furthermore, the ink production and printing processes must comply with hygiene regulations to prevent food contamination. Of course, vacuum sampling and storage of inks are essential for their use in these fields.
[0003] The vacuum sampling and storage device for food contact inks is an equipment used for safety testing of inks in food contact materials and products. Its design complies with national food safety standards such as GB 4806.14-2023. It achieves contamination-free sampling and sealed storage of samples through a vacuum system, ensuring hygiene and safety during the testing process and preventing the risk of ink migration or contamination.
[0004] While existing vacuum sampling and storage devices for food contact inks can meet the needs of most scenarios, they cannot be quickly disassembled and installed when the suction equipment is not in use or needs to be replaced. Therefore, a vacuum sampling and storage device for food contact inks is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figures 1-3This utility model provides an embodiment of a vacuum sampling and storage device for food contact ink, comprising a bottle body 1, a bottle stopper 6 installed at the top of the bottle body 1 to seal the bottle body 1, a sampling tube 2 fixedly connected to the middle of the bottle stopper 6 to draw out ink, a connecting mechanism installed outside the sampling tube 2 to connect to an outer tube 4, an outer tube 4 installed at the top of the connecting mechanism to transport ink to a corresponding location, a vacuum tube 15 fixedly connected to the middle of the bottle stopper 6 to create a vacuum in the bottle body 1 for subsequent ink extraction, a valve 27 installed outside the vacuum tube 15 to control the vacuum environment, a vacuum pump 5 slidably connected outside the vacuum tube 15 to create a vacuum in the bottle body 1, and a storage mechanism installed at the bottom of the bottle body 1 to store related tools; the connecting mechanism includes a moving component and a fixing component, the moving component including a connecting tube 18 slidably connected to the outside of the sampling tube 2 and the outer tube 4, through which ink can be drawn. The sampling tube 2 and the outer tube 4 are better connected by the connecting tube 18. Moving ring blocks 3 are slidably connected to the outer sides of both ends of the connecting tube 18, facilitating operator operation. Positioning rings 14 are fixedly connected to both ends of the connecting tube 18 to prevent the moving ring blocks 3 from dislodging and damaging the equipment. Springs 13 are fixedly connected to both outer ends of the connecting tube 18, allowing the moving ring blocks 3 to quickly return to their original position. The ends of the two springs 13 are fixedly connected to the inner sides of the two moving ring blocks 3. The fixed component includes multiple locking blocks 17, which tightly connect the sampling tube 2 and the outer tube 4. The multiple locking blocks 17 are all located inside the connecting tube 18. Two movable ring blocks 3 are slidably connected to the outside of the multiple locking blocks 17. The locking of the locking blocks 17 can be controlled by moving the movable ring blocks 3. The external parts of the sampling tube 2 and the outer tube 4 are fixedly connected with collars 16. The collars 16 and the locking blocks 17 are locked together. Through the tight fixing of the locking blocks 17 and the collars 16, the tight connection between the sampling tube 2 and the outer tube 4 can be achieved.
[0035] Reference Figure 1 , Figure 2 and Figure 4The storage mechanism includes an opening and closing component, a snap-fit component, and a fixing component. The opening and closing component includes a housing 9, which is fixedly connected to the bottom of the bottle 1. The housing 9 is used to store tools. A door panel 8 is rotatably connected to the outside of the housing 9 to prevent dust from entering the housing 9. The snap-fit component includes a housing 10, which is fixedly connected to the outside of the door panel 8 to protect internal parts from damage. A pin 20 is slidably connected inside the housing 10 to securely engage the equipment. A spring 21 is fitted on the outside of the pin 20 to allow the pin 20 to quickly return to its original position for easy operation. A limit plate 22 is fixedly connected to the outside of the pin 20 to prevent the pin from popping out due to excessive elasticity. The fixing component includes a plate 11, which is fixedly connected to the outside of the housing 9 to assist the pin 20 in engaging. A slot 23 is provided in the middle of the plate 11, and the pin 20 engages with the slot 23.
[0036] Reference Figure 1 , Figure 5 and Figure 6 The sampling tube 2 is externally fixedly connected to a rod 19, and the outer tube 4 has an insertion hole 26. The rod 19 and the insertion hole 26 are interlocked. By inserting the rod 19 into the insertion hole 26, the sampling tube 2 and the outer tube 4 can be tightly connected to prevent ink leakage. The bottom of the vacuum pump 5 is fixedly connected to a slider 24, and the vacuum tube 15 has a groove 25 inside. The slider 24 is slidably connected inside the groove 25. By setting the slider 24 on the vacuum pump 5, the vacuum pump 5 can be more easily sucked up, and at the same time, it also has a better sealing effect. The bottle body 1 is externally fixedly connected to a handle 7. The handle 7 makes it easier for the operator to move the equipment to the required location.
[0037] Working principle: First, when it is necessary to connect the sampling tube 2 and the outer tube 4, the moving ring block 3 is moved to both sides and the spring 13 is squeezed. At this time, the locking block 17 inside the connecting tube 18 will retract into the connecting tube 18. Then, the outer tube 4 is inserted and the insertion rod 19 is inserted into the insertion hole 26 to secure it. Since there is a sealing ring 12 on the outside of the sampling tube 2 and the outer tube 4, there will be no leakage. Then, when you release your hand, due to the elasticity of the spring 13, the moving ring block 3 will quickly return to the center and squeeze the locking block 17, locking the locking block 17 into the collar 16 outside the oil pipe, thus tightly and quickly connecting the outer tube 4 and the sampling tube 2.
[0038] Secondly, when the device is not in use, the parts that are installed during use can be stored inside the housing 9. At this time, pull the latch 20, and the limiting plate 22 will move with the latch 20 and compress the second spring 21. When the latch 20 is completely pulled out of the slot 23, open the door panel 8. Then you can put the tools in. After you have put them in, turn the door panel 8 back and release the hand that pulled the latch 20. Due to the elasticity of the second spring 21, the latch 20 will immediately return to the center, tightly fixing the door panel 8 and the housing 9. And due to the action of the limiting plate 22, the latch 20 will not be popped out.
[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
