Description

Technical Field

[0001] This invention relates to the field of resin production testing technology, and in particular to a testing device for epoxy resin production. Background Technology

[0002] The solid resin softening point tester (ring and ball method) is mainly used to determine the softening temperature of thermosetting materials such as solid epoxy resin. Its core significance lies in accurately detecting the softening point to determine the molecular weight, degree of polymerization reaction, and applicable processing temperature of the resin, providing key data support for the production quality control, grade differentiation, and curing process optimization of solid epoxy resin. Its working principle is to pour molten solid resin into a standard brass sample ring, cool it to form, and place it on the instrument support. Under the action of gravity of the steel ball, the bath liquid is heated at a constant rate. When the resin softens to the point where the steel ball pulls the resin down and touches the bottom plate, the temperature at this point is the softening point.

[0003] Existing solid resin softening point testers require pouring hot-melt resin into the test ring before testing, and then allowing the resin inside the ring to solidify before testing. This method easily generates bubbles during the cooling process, leading to inconsistencies between the solid resin in the sample and the actual production parameters, resulting in performance deviations between the test data and the actual values. In existing technologies, when the resin is squeezed by a sphere, the weight of the sphere can cause wear, leading to deviations in the pressure applied to the resin surface and reducing test accuracy. Furthermore, when the softened resin is squeezed by a sphere, the surface temperature of the sphere is low, causing the softened resin to solidify easily on the sphere surface, increasing the contact area between the sphere and the resin, and further reducing test accuracy. Additionally, existing resin softening point testers are often used at an angle to the horizontal plane, but they can only test the softening point when the resin is horizontal, and cannot test the softening point at an inclined angle.

[0013] Preferably, the shaking forming mechanism includes two symmetrically arranged fixed columns, with a second motor respectively arranged on the inner side of the two fixed columns, and a second fixed body respectively fixedly connected to the transmission shaft end of the two second motors. Two sets of first fixed plates are symmetrically connected to the side of the main body cylinder, and a first guide block is slidably connected in each set of first fixed plates.

[0014] Preferably, each set of first fixing plates has a first motor fixedly connected to its end, the drive shaft ends of the two first motors are fixedly connected to a first threaded rod, the two first threaded rods are respectively configured to be threadedly engaged with the first guide block, and the lower ends of the two fixing columns are fixedly connected to a support plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The first electric telescopic rod extends and retracts according to the thickness of the resin being tested, making it suitable for testing resins of different thicknesses. Then, the temperature-regulating ring is activated, first channeling hot air through the telescopic tube into the first cavity to preheat the inner surface of the first fixed body. Molten resin is then poured into the first fixed body. The temperature-regulating ring gradually lowers the temperature, and the gas inside the first fixed body enters the top block through the gas supply pipe, then exits through the first through-hole and the vent. Simultaneously, the third motor drives the second fixed plate to rotate, and the temperature-regulating ring channels temperature-regulating gas through the telescopic tube into the fourth cavity, then exits through the vent pipe into the fourth fixed body, and finally exits through several fifth through-holes. This ensures that all devices in contact with the molten resin are preheated, preventing sudden cooling and deformation of the resin surface during injection, improving the cooling quality of the readings. Furthermore, during subsequent cooling and heating of the resin, the upper and lower surfaces and sides of the resin can receive the same temperature simultaneously, reducing the occurrence of cavitation due to uneven heating during cooling. This makes the cooled readings closer to the quality of readings in actual production, improving the accuracy of the test. The first motor drives the first threaded rod to move back and forth, thereby driving the main body cylinder to move up and down back and forth through the first guide block. During the resin cooling process, the gas in the hot melt resin is discharged. At the same time, when the rotating second fixed plate drives the top plate to cool the lower end of the resin, the water on the resin surface can be pushed into the upper end of the second fixed plate and then enters the water-absorbing material through the air jet groove for storage, so that the value after cooling and molding is consistent with the value density in actual production. The fourth and fifth motors are activated, driving the second and third threaded rods to rotate respectively. This, in turn, moves the third guide block to any point on the resin. Simultaneously, the multi-stage electric telescopic rod retracts, causing the top block to heat the upper surface of the resin. Once the resin reaches the predetermined temperature, the fourth and fifth motors move the top block to the center of the resin, retracting the multi-stage electric telescopic rod. The top block then compresses the resin. The pressure applied to the resin remains constant based on the readings from the second pressure sensor, improving detection accuracy. The first pressure sensor reading determines whether the resin has reached its softening point. Attached Figure Description

[0028] Specifically, the fourth and fifth motors drive the second threaded rod 333 and the third threaded rod 336 to rotate, thereby cooperating to move the third guide block 343 to any point on the resin. At the same time, the multi-stage electric telescopic rod 36 retracts, driving the top block 310 to heat the upper surface of the resin. When the resin is heated to a predetermined temperature, the fourth and fifth motors drive the top block 310 to move to the center of the resin, retract the multi-stage electric telescopic rod 36, and squeeze the resin through the top block 310. The pressure applied to the resin is kept constant by the value of the second pressure sensor.

[0029] In this embodiment, the side of the main body cylinder 1 is provided with a shaking forming mechanism 2 for shaking and rotating the main body cylinder 1.

[0030] The shaking forming mechanism 2 includes two symmetrically arranged fixed columns 22. The inner sides of the two fixed columns 22 are respectively provided with second motors 29. The transmission shaft ends of the two second motors 29 are respectively fixedly connected to second fixing bodies 38. The sides of the main body cylinder 1 are symmetrically connected with two sets of first fixing plates 24. Each set of first fixing plates 24 is slidably connected with a first guide block 26. The ends of the two first guide blocks 26 are respectively provided with first placement grooves 27. The two first placement grooves 27 are respectively rotatably engaged with the connecting rod 28.

[0031] Each set of first fixing plates 24 is fixedly connected to a first motor 23 at its end. The drive shaft ends of the two first motors 23 are fixedly connected to first threaded rods 25. The two first threaded rods 25 are respectively connected to the first guide blocks 26 through threaded engagement. The lower ends of the two fixing columns 22 are fixedly connected to support plates 21.

[0032] Specifically, the two second motors 29 drive the connecting rod 28 to rotate, thereby causing the open end of the main body cylinder 1 to be in the upper position. Then, the first electric telescopic rod 33 extends, and the first electric telescopic rod 33 drives the second fixing plate 320 to move upward along the inner side of the first fixing body 35.

[0033] In use, the support plate 21 is placed on a horizontal surface. Then, the two second motors 29 are started, which drive the connecting rod 28 to rotate, thereby bringing the open end of the main body cylinder 1 to the top. Then, the first electric telescopic rod 33 extends, driving the second fixing plate 320 to move upward along the inner side of the first fixing body 35. The first electric telescopic rod 33 extends and retracts according to the resin thickness being detected, and can be used to detect resins of different thicknesses. Then, the temperature regulating ring 34 is started. The temperature regulating ring 34 first brings the hot air flow through the telescopic tube into the first cavity 312, thereby preheating the inner side of the first fixing body 35. Then, the molten resin is poured into the first fixing body 35. Then, the temperature regulating ring 34 gradually lowers the temperature, and the gas in the first fixing body 35 passes through... The gas supply pipe 39 enters the top block 310 and then exits through the first through hole 316 and the vent 311. At the same time, the third motor 32 drives the second fixed plate 320 to rotate. The temperature regulating ring 34 introduces the temperature regulating gas into the fourth empty slot 326 through the telescopic pipe, and then discharges it into the fourth fixed body 339 through the vent pipe 338. Finally, it is discharged through several fifth through holes 341. This ensures that all devices in contact with the molten resin are preheated, preventing the surface of the resin from suddenly cooling and deforming during injection, improving the cooling quality of the resin. In the subsequent cooling and heating process of the resin, the upper and lower end faces and the side faces of the resin can be subjected to the same temperature at the same time, reducing the occurrence of cavitation due to uneven heating during numerical cooling. This makes the cooled values ​​closer to the values ​​in actual production, improving the accuracy of the test.

[0034] When the molten resin cools and solidifies, the two first motors 23 are started. The first motors 23 drive the first threaded rods 25 to move back and forth, thereby driving the main body cylinder 1 to move up and down through the first guide block 26. This allows the gas in the hot molten resin to be discharged during the resin cooling process. At the same time, when the rotating second fixed plate 320 drives the top plate 340 to cool the lower end of the resin, the water on the resin surface can be pushed into the upper end of the second fixed plate 320. Then, it enters the water-absorbing material through the air jet groove 321 and is stored there. This makes the value after cooling and solidification consistent with the value density in actual production, improving the accuracy of subsequent testing.

[0035] Before heating the cooled and molded resin, the two second motors 29 first rotate the main body cylinder 1 to an angle with the opening facing downwards, thereby expelling moisture from the resin surface. Then, they rotate according to the measured angle, thus enabling the device to test the softening point of the resin at different angles. Before the test, the fourth and fifth motors are started, which drive the second threaded rod 333 and the third threaded rod 336 to rotate, thereby cooperating to move the third guide block 343 to any point on the resin. At the same time, the multi-stage electric telescopic rod 36 retracts, driving the top block 310 to heat the upper surface of the resin. When the resin is heated to the predetermined temperature, the fourth and fifth motors drive the top block 310 to move to the center of the resin, retract the multi-stage electric telescopic rod 36, and squeeze the resin through the top block 310. The value of the second pressure sensor ensures that the pressure applied to the resin remains constant, improving the accuracy of the test. The value of the first pressure sensor 342 determines whether the resin has reached the softening point.
