Description

Technical Field

[0001] The present application relates to the technical field of dyne pens, and in particular to a simple surface tension test pen. Background Art

[0002] Most plastic films (such as polyester films) are non-polar polymers with low surface tension. Known inks and adhesives cannot adhere firmly to them. Therefore, their surfaces must be treated with corona method to break the chemical bonds of plastic molecules and degrade them. A large amount of ozone will be generated during discharge. Ozone is a strong oxidant that can oxidize plastic molecules to produce carbonyl and peroxide groups with strong polarity, thereby increasing their surface energy. The printing effect of film materials is greatly affected by the corona value of the film materials, so dyne value testing is very necessary.

[0003] At present, the main testing methods for the corona value (dyne value) of film materials are: dyne liquid (configured according to standard GB-14216-2008), dyne pen and water drop angle tester.

[0004] Among them, the shelf life of dyne liquid is only 6 months, it is colorless, and it needs to be dipped with a cotton swab when used. This detection method consumes a lot of dyne liquid, and the cotton swab may absorb unevenly, resulting in uneven smearing of dyne liquid. The dyne pen is more accurate in testing, generally available in orange-red, blue, green, etc., but its market price is high, resulting in high testing costs. The water drop angle tester: Although its test results are more accurate, the test efficiency is low due to the complicated test steps. Therefore, a simple surface tension test pen is proposed to solve the above-mentioned related technical problems. Summary of the invention

[0014] By adopting the above technical solution, when the connecting pen tip is pulled out for use, the opening and closing rubber ring rebounds upward due to the elastic force, and when the opening and closing rubber ring is reset, the detection pen tip passes through the central hole of the opening and closing rubber ring, and the opening and closing rubber ring scrapes off the dyne liquid on the outside of the detection pen tip, and the opening and closing rubber ring drives the pull rope connecting block to slide upward through the connecting axis during the resetting process, and drives the pull rope connecting block to pull the lifting connecting ring through the opening and closing lifting rope during the resetting process, so that the two sets of liquid outlet opening and closing plates are pulled, and the liquid outlet is opened to release the liquid, and when the connecting pen tip is fully inserted into the pen cap, the two sets of liquid outlet opening and closing plates collide with each other, and the liquid outlet is sealed.

[0015] Preferably, a threaded connection block is provided at the connection between the pen body and the connecting pen tip, and threads are provided on the inner and outer sides of the threaded connection block.

When the detection pen tip is fully connected in the connecting pen tip, the liquid guide block is plugged into the cotton core. Since the detection pen tip, the plug-in fixing block and the liquid guide block are all made of fiber materials, the dyne liquid in the cotton core can flow along the plug-in fixing block and the liquid guide block to the position of the detection pen tip.

[0022] By adopting the above technical solution, when dyne liquid is injected through a syringe, the sealing plug is squeezed by the injection head of the syringe, and the squeezing spring is deformed during the movement of the squeezing sealing plug. At this time, the squeezing sealing plug drives the valve core connecting rod and the valve core connected thereto to move in a direction away from the switch protrusion, and at the same time, the valve core drives the sealing piston to move away from the switch protrusion, thereby completing the opening of the passage at the switch protrusion, and when the injection work is completed, the squeezing sealing plug is reset by the rebound force of the pressing spring, and then the passage at the switch protrusion is closed by resetting the valve core and the sealing piston.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. Compared with the prior art, this simple surface tension test pen is more convenient and more efficient than the dyne liquid test. Through the double-head design, different proportions of dyne liquid can be injected into the two sections of the pen body, so that the test pen body can test two data at the same time. The pen body is infused with dyne liquid through the infusion hole in the infusion groove, and the dyne liquid is input into the infusion box, and the dyne liquid in the infusion box is input into the cotton core through the liquid guide tube. When the detection pen head is fully connected to the connecting pen head, the liquid guide plug is plugged into the cotton core, so that the dyne liquid in the cotton core can flow into the position of the detection pen head along the plug-in fixing block and the liquid guide plug.

[0026] 2. Compared with the prior art, the simple surface tension test pen can discharge the dyne liquid in the pen cap when the pen tip is pulled out to ensure that the dyne liquid on the outside of the detection pen tip is a liquid that has not come into contact with the air, thereby making the detection result more accurate. When the detection pen tip is inserted into the pen cap, the connecting pen tip presses the opening and closing rubber ring downward, so that the opening and closing rubber ring and the connecting pull rod connected to it are bent downward, and the detection pen tip and the connecting pen tip are wrapped by the opening and closing rubber ring and the anti-collision rubber pad, so that the detection pen tip, the anti-collision rubber pad and the opening and closing rubber ring form a relatively closed space, thereby preventing the dyne liquid from leaking out of the pen cap, and the dyne liquid overflowing from the detection pen tip is always in contact with the detection pen tip in the relatively closed space formed, thereby The detection pen tip is always kept moist to save the use of dyne liquid. When the connecting pen tip is pulled out for use, the opening and closing rubber ring rebounds upward under the action of elastic force. After the opening and closing rubber ring is reset, the detection pen tip passes through the central hole of the opening and closing rubber ring, and the dyne liquid on the outside of the detection pen tip is scraped off by the opening and closing rubber ring. During the resetting process, the opening and closing rubber ring drives the pull rope connecting block to slide upward through the connecting axis, and during the resetting process, drives the pull rope connecting block to pull the lifting connecting ring through the opening and closing lifting rope, so that the two sets of liquid outlet opening and closing plates are pulled, and the liquid outlet is opened to release liquid. When the connecting pen tip is fully inserted into the pen cap, the two sets of liquid outlet opening and closing plates collide with each other to seal the liquid outlet.

[0027] 3. Compared with the prior art, the surface tension simple test pen has increased the sealing performance of the injection structure, which can prevent the dyne liquid from flowing out when injecting the dyne liquid. The pen body is used to infuse the dyne liquid through the infusion hole in the infusion groove, and the dyne liquid is input into the infusion box, and the dyne liquid in the infusion box is input into the cotton core through the liquid guide tube, and the infusion groove is buckled by the sealing cover. When the cotton core is inserted into the pen body, the fixed buffer gasket cushions the movement of the cotton core during insertion to prevent the cotton core from bending, and the fixed buffer gasket limits the position of the cotton core. When the dyne liquid is infused through the syringe, the injection head of the syringe squeezes the seal. Sealing plug, the extruded sealing plug squeezes the pressing spring to deform during the movement, and at this time, the extruded sealing plug drives the valve core connecting rod and the valve core connected to it to move in the direction away from the switch protrusion, and at the same time, the valve core drives the sealing piston to move away from the switch protrusion, thereby completing the opening of the passage at the switch protrusion, and when the injection work is completed, the extruded sealing plug is reset by the rebound force of the pressing spring, and then the passage at the switch protrusion is closed by resetting the valve core and the sealing piston. When the passage at the switch protrusion is opened, the opening of the switch protrusion is connected with the infusion tube, and the pressure of the syringe allows the dyne liquid to be input into the infusion box along the infusion tube.

When the test pen body 1 is idle, the test pen body 1 can be hung on the pen holder through the pen hanger 21, and the test pen tip 4 is plugged and fixed into the pen tip connection port 32 of the connecting pen tip 3 through the plug-in fixing block 41, so that the test pen tip 4 can be replaced when it is damaged, and when the test pen tip 4 is completely connected to the connecting pen tip 3, the liquid guide plug 42 is plugged into the cotton core 5, so that the dyne liquid in the cotton core 5 can flow into the position of the test pen tip 4 along the plug-in fixing block 41 and the liquid guide plug 42; The pen body 11 is infused with dyne liquid through the infusion hole 7 in the infusion groove 111, and the dyne liquid is input into the infusion box 115, and the dyne liquid in the infusion box 115 is input into the cotton core 5 through the catheter 117, and the infusion groove 111 is buckled by the sealing cover 6, and when the cotton core 5 is inserted into the pen body 11, the fixed buffer gasket 116 buffers the movement of the cotton core 5 during insertion to prevent the cotton core 5 from bending, and the fixed buffer gasket 116 limits the position where the cotton core 5 is extended, and when the dyne liquid is infused through the syringe, the sealing plug 72 is squeezed by the injection head of the syringe, and the sealing plug 72 squeezes the pressing spring 74 to deform during the movement, and this When the injection is completed, the sealing plug 72 is pressed and reset by the rebound force of the pressing spring 74, and then the valve core 722 and the sealing piston 723 are reset to close the passage at the switch protrusion 73. When the passage at the switch protrusion 73 is opened, the opening of the switch protrusion 73 is connected to the infusion tube 71, and the pressure of the syringe allows the dyne solution to be input into the infusion box 115 along the infusion tube 71. When the detection pen tip 4 is inserted into the pen cap 2, the connecting pen tip 3 presses the opening and closing rubber ring 27 downward, so that the opening and closing rubber ring 27 and the connecting pull rod 28 connected thereto are bent downward, and the detection pen tip 4 and the connecting pen tip 3 are wrapped by the opening and closing rubber ring 27 and the anti-collision rubber pad 22, so that the detection pen tip 4, the anti-collision rubber pad 22 and the opening and closing rubber ring 27 form a relatively closed space, thereby preventing the dyne liquid from leaking out of the pen cap 2, and the dyne liquid overflowing from the detection pen tip 4 is always in contact with the detection pen tip in the relatively closed space. The detection pen tip 4 is in contact with the detection pen tip 4, so that the detection pen tip 4 is always kept moist to save the use of dyne liquid. When the connecting pen tip 3 is pulled out for use, the opening and closing rubber ring 27 rebounds upward under the action of elastic force. After the opening and closing rubber ring 27 is reset, the detection pen tip 4 passes through the central hole of the opening and closing rubber ring 27, and the dyne liquid on the outside of the detection pen tip 4 is scraped off by the opening and closing rubber ring 27. During the reset process, the opening and closing rubber ring 27 drives the pull rope connecting block 281 to reset and slide upward through the connecting shaft, and During the resetting process, the pull rope connecting block 28 is driven to pull the lifting connecting ring 253 through the opening and closing lifting rope 282, so that the two sets of liquid outlet opening and closing plates 252 are pulled, and the liquid outlet 251 is opened to release liquid. When the connecting pen tip 3 is fully inserted into the pen cap 2, the two sets of liquid outlet opening and closing plates 252 are in conflict with each other, and the liquid outlet 251 is sealed. The connecting pen tip 3 is fixed between the fixed clamping block 23 and the limiting clamping ring 24 by the fixing convex ring 31 to prevent the pen cap 2 from falling off when not in use. The pen tip 3 and the pen cap 2 are threadedly connected to the pen body 11 through a threaded connection block 113, and the threaded connection is used to increase the stability and sealing of the connection. On the one hand, it can prevent the connection from falling off, and on the other hand, it can prevent the dyne liquid from leaking out. When the cotton core 5 is inserted into or removed from the pen body 11, the cotton core limiting block 114 limits the position of the cotton core 5 to prevent the cotton core 5 from shifting when being removed or inserted. The cotton core 5 can prevent the dyne liquid in the cotton core 5 from leaking out through the leak-proof film 51.
