Description

Technical Field

[0001] This utility model relates to the field of epoxy resin technology, specifically to an epoxy resin testing device. Background Technology

[0002] Epoxy resin, also known as synthetic resin, is a type of organic polymer containing two or more epoxy groups in its molecular structure. It is a thermosetting plastic. During the production process of epoxy resin, it is necessary to conduct random inspections and test the viscosity of epoxy resin, which requires the use of epoxy resin testing equipment.

[0003] Current epoxy resin testing devices, such as the one disclosed in CN221528327U, include a support platform and a testing instrument. The support platform is equipped with a cooling chamber and a heating chamber. Temperature changes are achieved through the cooling and heating chambers. First, the cover plates that snap together at the top of the cooling and heating chambers are opened, and liquids for heating and cooling are injected into the interior of the chambers. Then, the cover plates are closed, and a mixing tank is placed on the support platform. During testing, the viscosity of the epoxy resin varies with temperature; as the temperature increases, the viscosity decreases. During stirring, if the temperature is too low, the liquid is heated through heat pipes in the heating chamber, and the heat is conducted to the mixing tank, thus heating the tank. If the temperature is too high, the cooling pipes are used to lower the temperature. The cooling and heating chambers on both sides allow for temperature changes, simulating the viscosity of epoxy resin under different temperature conditions, resulting in more comprehensive test results.

[0004] Although existing epoxy resin testing devices can simulate the viscosity of epoxy resin under different temperature conditions, making the test results more comprehensive, it has been found in use that after testing epoxy resin, in order not to affect the testing of the next batch of epoxy resin, the mixing tank needs to be disassembled and cleaned. During the disassembly and cleaning of the mixing tank, the testing device stops working for a long time, resulting in low overall working efficiency and inconvenience of the epoxy resin testing device.

[0005] The purpose of this invention is to provide an epoxy resin testing device to solve the problems currently existing in the market as described in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an epoxy resin testing device, comprising a base, a rotating seat rotatably connected to the top of the base, and the rotating seat being driven to rotate by a driving mechanism, wherein...

[0007] A hydraulic rod is installed on the top of one side of the base, a top frame is installed on the top of the hydraulic rod, a rotational viscometer body and a controller are installed on the top frame, a splash guard is installed on the top frame corresponding to the bottom of the rotational viscometer body, and a rotating shaft is installed on the shaft end of the rotational viscometer body;

[0008] A stirring rod is installed at the bottom of the rotating shaft. Heating resistors and temperature sensors are installed on the bottom of both sides of the splash guard. Placement slots are symmetrically opened on the top of both sides of the rotating seat. A barrel is placed in the placement slot. When the rotating seat rotates, the clamping mechanism automatically clamps or releases the barrels on both sides.

[0009] Preferably, the driving mechanism includes a worm gear, the worm gear is installed on the shaft end of the rotating seat corresponding to the base, the driving motor is installed on the bottom side of the base corresponding to the worm gear, and the worm is installed on the shaft end of the driving motor corresponding to the worm gear, the worm meshing with the worm gear.

[0010] Preferably, the rotating shaft passes through the middle of the splash guard and is rotatably connected to the splash guard.

[0011] Preferably, the rotating seat has symmetrically formed positioning grooves at the bottom of the corresponding placement groove, and the barrel body has a positioning block fixedly connected to the bottom of the positioning groove, the external dimensions of the positioning block matching the internal dimensions of the positioning groove.

[0012] Preferably, the clamping mechanism includes a sliding groove. The rotating seat has symmetrical sliding grooves on both sides of the top of the placement groove. A slider is provided in the sliding groove. A clamping frame is installed on the top of the slider. A locking block is symmetrically fixedly connected to the inner side of the clamping frame. A locking groove is provided on the outer side of the barrel corresponding to the locking block. A sliding rod groove passes through the bottom of the rotating seat corresponding to the sliding groove. A sliding rod is fixedly connected to the bottom of the sliding rod groove corresponding to the slider. A transmission groove is provided on the top of the base. The bottom end of the sliding rod is located inside the transmission groove.

[0013] Preferably, the transmission groove is composed of two arc-shaped grooves, and the inner diameter of the arc-shaped groove on the side of the transmission groove closer to the hydraulic rod is smaller than the inner diameter of the arc-shaped groove on the side farther from the hydraulic rod, and the two arc-shaped grooves of the transmission groove are connected by an oblique transition.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This invention features two sets of barrels mounted on a rotating base. A drive mechanism rotates the base, allowing the positions of the barrels to be interchanged. This enables the rotational viscometer to test the viscosity of epoxy resin in one barrel via a rotating shaft and stirring rod, while simultaneously disassembling and cleaning the other barrel to prepare for the next batch of epoxy resin to be tested. By alternating the use of the two sets of barrels, the invention avoids prolonged downtime during barrel cleaning and epoxy resin replacement, effectively improving the working efficiency of the epoxy resin testing device.

[0016] In this invention, when the rotating seat rotates, it drives the sliding rod to move within the transmission groove. When the sliding rod rotates towards the hydraulic rod, it moves from a larger radius arc groove into a smaller radius arc groove, causing the sliding rods on both sides of the placement groove to move closer together, and vice versa. As the sliding rod moves, it can drive the slider to move within the groove. Furthermore, through the rotation of the rotating seat, the slider can drive the two clamping frames to move closer or further apart. When the clamping frames move closer together, they drive the locking blocks into the slots of the barrel to fix the barrel and prevent it from shaking during the inspection process. When the clamping frames move further apart, they can release the barrel from its fixed state. Through the clamping mechanism, the barrel in the inspection state can be automatically fixed during the rotation of the rotating seat, and the barrel to be disassembled and cleaned can be automatically released from its fixed state, so as to automatically fix or loosen the barrel according to its working state.

[0017] In this invention, when placing the bucket, the bottom of the bucket is placed in the placement groove, and at the same time the bucket moves the positioning block into the interior of the positioning groove. The positioning structure formed by the positioning block and the positioning groove positions the bucket so that the bucket can be clamped and fixed in the future, and the placement of the bucket can be prevented from being offset.

[0024] 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.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: an epoxy resin testing device, including a base 1, a rotating seat 2 rotatably connected to the top of the base 1, and the rotating seat 2 being driven to rotate by a drive mechanism.

[0026] A hydraulic rod 6 is installed on the top of one side of the base 1. A top frame 7 is installed on the top of the hydraulic rod 6. A rotational viscometer body 8 and a controller 9 are installed on the top frame 7. A splash cover 10 is installed on the top frame 7 corresponding to the bottom of the rotational viscometer body 8. A rotating shaft 11 is installed on the shaft end of the rotational viscometer body 8.

[0027] A stirring rod 12 is installed at the bottom of the rotating shaft 11. A heating resistor 13 and a temperature sensor 14 are respectively installed on the bottom of both sides of the splash cover 10. Placement slots 15 are symmetrically opened on the top of both sides of the rotating seat 2. A barrel 16 is set in the placement slot 15. When the rotating seat 2 rotates, the clamping mechanism automatically clamps or releases the barrels 16 on both sides.

[0028] Two sets of barrels 16 are set on the rotating base 2, and the rotating base 2 is driven to rotate by the drive mechanism, thereby changing the position of the two barrels 16. When the rotational viscometer body 8 detects the viscosity of epoxy resin in one barrel 16 through the rotating shaft 11 and stirring rod 12, the other barrel 16 can be disassembled and cleaned, and the next batch of epoxy resin to be tested can be prepared. By using the two sets of barrels 16 alternately, the detection device avoids long downtime during the cleaning of barrels 16 and replacement of epoxy resin, effectively improving the working efficiency of the epoxy resin detection device.

[0029] Please see Figures 1 to 5The drive mechanism includes a worm gear 3. The worm gear 3 is installed on the shaft end of the rotating seat 2 corresponding to the base 1. The drive motor 4 is installed on the bottom side of the base 1 corresponding to the worm gear 3. The worm 5 is installed on the shaft end of the drive motor 4 corresponding to the worm gear 3. The worm 5 meshes with the worm gear 3. The rotating shaft 11 passes through the middle of the splash cover 10 and is rotatably connected to the splash cover 10. When the drive motor 4 is working, the drive motor 4 drives the worm 5 to rotate. The worm 5 drives the worm gear 3 to rotate through meshing. The worm gear 3 drives the rotating seat 2 to rotate through a fixed connection. In turn, the rotating seat 2 changes the position of the two barrels 16.

[0030] Please see Figures 1 to 5 The rotating seat 2 has a symmetrically provided positioning groove 17 at the bottom of the placement groove 15. The barrel 16 is fixedly connected to the bottom of the positioning groove 17. The external dimensions of the positioning block 18 match the internal dimensions of the positioning groove 17. When placing the barrel 16, the bottom of the barrel 16 is placed in the placement groove 15. At the same time, the barrel 16 drives the positioning block 18 into the interior of the positioning groove 17. The positioning structure formed by the positioning block 18 and the positioning groove 17 positions the barrel 16 so that the barrel 16 can be clamped and fixed in the future to prevent the barrel 16 from shifting.

[0031] Please see Figures 1 to 5The clamping mechanism includes a slide groove 19. The top of the rotating seat 2 is symmetrically provided with slide grooves 19 on both sides near the placement groove 15. A slider 20 is installed inside the slide groove 19. A clamping frame 21 is installed on the top of the slider 20. A locking block 22 is symmetrically fixedly connected to the inner side of the clamping frame 21. A locking groove 23 is provided on the outer side of the barrel body 16 corresponding to the locking block 22. A sliding rod groove 24 passes through the bottom of the rotating seat 2 corresponding to the slide groove 19. A sliding rod 25 is fixedly connected to the bottom of the slider 20 corresponding to the sliding rod groove 24. A transmission groove 26 is provided on the top of the base 1. The bottom end of the sliding rod 25 is located inside the transmission groove 26. The transmission groove 26 consists of two arc-shaped grooves. The inner diameter of the arc-shaped groove on the side of the transmission groove 26 closer to the hydraulic rod 6 is smaller than the inner diameter of the arc-shaped groove on the side farther from the hydraulic rod 6. The two arc-shaped grooves of the transmission groove 26 are connected at an oblique transition. When the rotating seat 2 rotates, the rotating seat 2 drives the sliding rod 25 to move within the transmission groove 26. As the sliding rod 25 moves towards the hydraulic rod 6... During rotation, the slide bar 25 moves from the larger radius arc groove into the smaller radius arc groove, causing the slide bars 25 on both sides of the placement groove 15 to move closer to each other, and vice versa. When the slide bar 25 moves, it can drive the slider 20 to move within the slide groove 19. In turn, through the rotation of the rotating seat 2, the slider 20 can drive the clamping frames 21 on both sides to move closer or further apart. When the clamping frames 21 move closer, the clamping frames 21 drive the locking block 22 into the locking groove 23 of the barrel 16 to fix the barrel 16 and prevent the barrel 16 from shaking during the inspection process. When the clamping frames 21 move further apart, the barrel 16 can be released from the fixed state. Through the clamping mechanism, the barrel 16 in the inspection state can be automatically fixed during the rotation of the rotating seat 2, and the barrel 16 to be disassembled and cleaned can be automatically released from the fixed state, so as to automatically fix or loosen the barrel 16 according to the working state of the barrel 16.

[0032] Working Principle: This epoxy resin testing device has two sets of barrels 16 mounted on a rotating base 2. A drive mechanism rotates the rotating base 2, thus swapping the positions of the two barrels 16. This allows the rotational viscometer body 8 to test the viscosity of the epoxy resin in one barrel 16 via the rotating shaft 11 and stirring rod 12, while the other barrel 16 is disassembled and cleaned, preparing the next batch of epoxy resin for testing. This alternating use of the two sets of barrels 16 avoids prolonged downtime during cleaning and epoxy resin replacement, effectively improving the working efficiency of the epoxy resin testing device. During epoxy resin viscosity testing, the hydraulic rod 6 lowers the top frame 7, allowing... The top frame 7 drives the rotating shaft 11 and stirring rod 12 into the tank 16, and the opening of the tank 16 is blocked by the splash cover 10. The rotating shaft 11 and stirring rod 12 are driven to rotate by the rotating viscometer body 8 to detect the viscosity of the epoxy resin (the rotating viscometer is a commonly used rotating viscosity testing instrument, so this solution directly uses the existing technology without explaining its working principle). At the same time, the controller 9 controls the heating resistor 13 to heat the epoxy resin, and the temperature of the epoxy resin is detected by the temperature sensor 14 (the heating resistor 13 and the temperature sensor 14 are existing technologies, which are directly used in this solution, so their models and working principles are not explained), thereby detecting the viscosity of the epoxy resin under different temperature conditions.

[0033] When the drive motor 4 is working, it drives the worm 5 to rotate. The worm 5, through meshing, drives the worm wheel 3 to rotate. The worm wheel 3, through a fixed connection, drives the rotating seat 2 to rotate. This rotating seat 2 then swaps the positions of the two barrels 16. When placing the barrel 16, the bottom of the barrel 16 is placed in the placement groove 15. Simultaneously, the barrel 16 drives the positioning block 18 into the positioning groove 17. The positioning structure formed by the positioning block 18 and the positioning groove 17 positions the barrel 16, facilitating subsequent clamping and fixing of the barrel 16 and preventing misalignment. Furthermore, when the rotating seat 2 rotates, it drives the sliding rod 25 to move within the transmission groove 26. As the sliding rod 25 rotates towards the hydraulic rod 6, it moves from the larger radius arc groove into the smaller radius arc groove. This mechanism allows the sliding rods 25 on both sides of the placement slot 15 to move closer together and further apart. When the sliding rods 25 move, they can drive the slider 20 to move within the sliding groove 19. Furthermore, through the rotation of the rotating seat 2, the slider 20 can drive the clamping frames 21 on both sides to move closer or further apart. When the clamping frames 21 move closer together, the clamping frames 21 drive the locking block 22 into the locking groove 23 of the barrel 16 to fix the barrel 16 and prevent the barrel 16 from shaking during the inspection process. When the clamping frames 21 move further apart, the barrel 16 can be released from its fixed state. Through the clamping mechanism, the barrel 16 in the inspection state can be automatically fixed during the rotation of the rotating seat 2, and the barrel 16 to be disassembled and cleaned can be automatically released from its fixed state, so as to automatically fix or loosen the barrel 16 according to its working state.
