Description

Technical Field

[0001] This utility model relates to the field of polyurethane adhesive technology, specifically to a testing device for polyurethane adhesives. Background Technology

[0002] Polyurethane adhesives are adhesives containing urethane groups (-NHCOO-) or isocyanate groups (-NCO) in their molecular chains. Polyurethane adhesives are broadly classified into two categories: polyisocyanates and polyurethanes. Because polyisocyanates contain isocyanate groups (-NCO) and urethane groups (-NH-COO-), polyurethane adhesives exhibit high reactivity and polarity. Adhesives can be tested for viscosity using a rotational viscometer to ensure their reliability in practical applications.

[0003] Existing patent CN219320017U discloses a viscosity testing device for adhesives, including a base with a positioning groove on the base, a test cup placed inside the positioning groove, a clamping mechanism for clamping the test cup on the base next to the test cup, a guide rod and a first screw vertically fixed on the base, a sliding seat on the guide rod, one end of the sliding seat being connected to the guide rod insert and the other end being connected to the first screw insert, an installation groove being opened on the end of the sliding seat near the first screw, an adjusting screw plate being horizontally arranged in the installation groove, the screw plate being threadedly connected to the first screw, and a viscosity tester mechanism being arranged on the side wall of the sliding seat near the test cup.

[0004] The aforementioned patents or existing testing devices have the following problems:

[0005] Existing testing devices use a single bolt to lock the placement plate in place after it slides. This positioning method is simple in structure but has poor stability and may also cause the placement plate to tilt. Utility Model Content

[0006] The purpose of this invention is to provide a testing device for polyurethane adhesives to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a testing device for polyurethane adhesives, comprising a fixed base, an organism mounted on the fixed base, a control panel on the surface of the organism, a detection head mounted on the organism, a fixed rod fixed on the fixed base, a placement plate mounted on the fixed rod, a material bucket placed on the placement plate, a sliding locking structure mounted on the placement plate, the sliding locking structure comprising a slider, a slider fixed on the placement plate, a screw mounted in the slider, a knob mounted on the screw, a threaded block connected to the screw, a connecting plate fixed on the threaded block, a pressure block fixed at the end of the connecting plate, a sliding opening mounted on the slider, and the fixed rod located in the sliding opening.

[0008] Preferably, a fixing plate is fixed in the middle of the slider, the screw passes through the fixing plate, and the screw is rotatably connected to the fixing plate.

[0009] Preferably, a spring is provided on the fixing plate, and one end of the spring is fixed to the surface of the threaded block.

[0010] Preferably, the connecting plate is inclined between the threaded block and the pressure block.

[0011] Preferably, a positioning rod is fixed to the surface of the fixing plate, and a sliding sleeve is provided on the connecting plate, the sliding sleeve sliding along the surface of the positioning rod.

[0012] Preferably, there are two positioning rods, and the number of sliding sleeves is the same as the number of positioning rods.

[0013] Preferably, an anti-slip pad is fixed to the surface of the pressure block, and the anti-slip pad is elastic.

[0014] Preferably, a slide rail is provided on the inner side of the slider, the pressure block is slidably connected to the slide rail, and the pressure block is in contact with the surface of the slide rail.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the sliding placement plate is slidable, the slider will slide along the surface of the fixed rod to ensure the stability of the placement plate during sliding. Turning the knob will drive the screw to rotate, and the threaded block will slide horizontally. Then, through the connecting plate, it will drive the pressure block to slide. The pressure block will press against the surface of the fixed rod located in the sliding opening. The pressure block pressing against the surface of the fixed rod can lock in place due to friction. The sliding locking structure locks the placement plate in place, ensuring the stability of the placement plate after locking. The slider sliding along the surfaces of the two fixed rods can also ensure that the placement plate will not be tilted. Attached Figure Description

Detailed Implementation

[0021] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0022] Please see Figure 1 and Figure 2 This utility model provides a testing device for polyurethane adhesives, including a fixed base 1, an organism 2 mounted on the fixed base 1, a control panel 3 mounted on the surface of the organism 2, a detection head 4 mounted on the organism 2, a fixed rod 5 fixed on the fixed base 1, the fixed rod 5 standing between the fixed base 1 and the organism 2, a placement plate 6 connected to the fixed rod 5, the placement plate 6 being able to slide vertically up and down along the surface of the fixed rod 5, a material bucket 7 placed on the placement plate 6, and a sliding locking structure 8 provided on the placement plate 6.

[0023] Specifically, the polyurethane adhesive is poured into the material tank 7 and then placed on the placement plate 6. By sliding the placement plate 6, it slides upward along the surface of the fixing rod 5, so that the detection head 4 extends into the material tank 7. The machine body 2 is turned on through the control panel 3, so that the detection head 4 rotates in the material tank 7, and the viscosity of the polyurethane adhesive fluid is measured.

[0024] Please see Figure 2 and Figure 3 This utility model provides a testing device for polyurethane adhesives. The sliding clamping structure 8 includes a slider 81. The slider 81 is fixed to the placement plate 6 by bolts. A screw 82 is rotatably connected to the slider 81. A knob 83 is fixed to the end of the screw 82. The knob 83 is rotatably connected to the slider 81. A threaded block 84 is threadedly connected to the screw 82. A connecting plate 85 is fixed to the threaded block 84 at an incline. A pressure block 86 is fixed to the end of the connecting plate 85. The inclined connecting plate 85 is inclined at 45°, which provides better support for the pressure block 86. A sliding opening 87 is provided on the slider 81, and the fixing rod 5 is located in the sliding opening 87.

[0025] A fixing plate 88 is fixed in the middle of the slider 81. The screw 82 passes through the fixing plate 88 and is rotatably connected to the fixing plate 88, ensuring the stability of the screw 82 when rotating. A spring 89 is provided on the fixing plate 88. One end of the spring 89 is fixed to the surface of the threaded block 84, making the connection between the screw 82 and the threaded block 84 more stable.

[0026] Preferably, a positioning rod 810 is fixed on the surface of the fixing plate 88, and a sliding sleeve 811 is provided on the connecting plate 85. The sliding sleeve 811 slides along the surface of the positioning rod 810. There are two positioning rods 810, and the number of sliding sleeves 811 is the same as that of the positioning rods 810, which effectively prevents the connecting plate 85 from being skewed or tilted, thus affecting the clamping effect of the pressure block 86.

[0027] The surface of the pressure block 86 is fixed with an anti-slip pad 812. The anti-slip pad 812 is elastic and has a better anti-slip effect. The inner side of the slider 81 is provided with a slide rail 813. The pressure block 86 is slidably connected to the slide rail 813, and the pressure block 86 is attached to the surface of the slide rail 813 to prevent the pressure block 86 from tilting.

[0028] Specifically, when the sliding placement plate 6 is slidable, the slider 81 will slide along the surface of the fixed rod 5 to ensure the stability of the placement plate 6 during sliding. Rotating the knob 83 will drive the screw 82 to rotate. Since the threaded block 84 is threadedly connected to the screw 82, the threaded block 84 will slide horizontally when the screw 82 rotates. Then, through the connecting plate 85, it will drive the pressure block 86 to slide. The pressure block 86 will press against the surface of the fixed rod 5 located in the sliding opening 87. The pressure block 86 can be locked by friction on the surface of the fixed rod 5. The sliding locking structure 8 locks the placement plate 6, ensuring the stability of the placement plate 6 after locking. The slider 81 slides along the surfaces of the two fixed rods 5, which also ensures that the placement plate 6 will not be tilted.

[0029] The above description is merely 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.
