Description

Technical Field

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

[0002] Epoxy resin has high viscosity and long curing time at room temperature. The high viscosity of epoxy resin makes it difficult to distribute it evenly in the processing stages such as mixing, casting and impregnation. Traditional preheating methods are unstable, inefficient and mostly unsuitable for high filler systems. Therefore, epoxy resin preheating devices have emerged.

[0003] For example, Chinese patent CN221549184U discloses a drying device for epoxy resin processing. In this solution, the mixed epoxy resin raw material is heated by the cooperation of a heating solenoid coil, a cooling pipe, and a drain pipe. When the epoxy resin is heated, water vapor is generated. The device can make the water vapor pass through a water pump, a water outlet pipe, and a drain pipe. Cold water circulates in the cavity, causing the water vapor generated by the epoxy resin to condense when it encounters cold air, thereby improving the quality of the preheated epoxy resin.

[0004] Based on the above-disclosed technical solutions and existing technologies, in some epoxy resin preheating devices, when condensing the generated water vapor, the condensed water falls down the outlet pipe. Most devices do not clean the outlet pipe. Since some cooled water may remain inside the pipe, it will affect the condensation effect of subsequent exhaust. Therefore, we propose an epoxy resin preheating device that can clean the outlet pipe, thereby improving the condensation effect and efficiency. Utility Model Content

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] This utility model provides, for example Figure 1-5An epoxy resin preheating device is shown, comprising a tank 1, a central shaft 6, a cleaning assembly 4, and a cooling pipe 19. A heating coil 2 is provided at the bottom of the tank 1, and an installation groove for the heating coil 2 is provided at the bottom of the tank 1. When installing the heating coil 2, it is necessary to first make individual coils and then connect them into a whole. After the induction coil is installed in the heating equipment, ensure that the distance between the coil and the workpiece is appropriate. Finally, connect the power supply and check whether the equipment connection is firm to ensure safety. A mounting shell 3 is fixedly connected to the top of the tank 1. The top and bottom of one side of the tank 1 are respectively connected to the feed pipe and the discharge pipe. The drive motor 7 is fixedly connected to the top of the mounting shell 3. The cleaning assembly 4 is provided inside the mounting shell 3. The mounting shell 3 is used to protect the cleaning assembly 4 and can extend the service life of the cleaning assembly 4. A water tank 5 is fixedly connected to one side of the tank 1. The water tank 5 is used to collect the water discharged from the water outlet pipe 20.

[0028] The bottom of the central shaft 6 is rotatably connected to the bottom of the tank 1, and the top of the central shaft 6 is fixedly connected to the drive motor 7. The outer side of the central shaft 6 is fitted with a spiral blade 8, which transports the epoxy resin at the bottom to the top for circulation, so that the epoxy resin can be heated evenly. The spiral blade 8 is provided with a limiting tube 9 on the outside. The limiting tube 9 is used to limit the feeding range of the spiral blade 8. If the range is too large, the epoxy resin will fall from the gap between the spiral blade 8 and the limiting tube 9, and the feeding circulation will not be successful. Both sides of the limiting tube 9 are connected to the inner wall of the tank 1 through connecting rods. The top of the central shaft 6 is fitted with a small gear 10, and a large gear 11 meshes with one side of the small gear 10.

[0029] The cleaning assembly 4 includes a disc 12. The top of the central shaft of the disc 12 is rotatably connected to the top of the inner wall of the mounting housing 3. The outer side of the central shaft of the disc 12 is connected to the inner wall of the large gear 11. It takes a certain amount of time for the epoxy resin to generate water vapor when heated, so the cleaning assembly 4 does not need to clean the cooling pipe 19 frequently. The small gear 10 drives the large gear 11 to rotate. The rotation frequency of the large gear 11 is lower than that of the small gear 10. A retaining shaft 13 is fixedly connected to the eccentric part at the bottom of the disc 12. A retaining sleeve is fitted on the outer side of the retaining shaft 13. A long rod 14 is fixedly connected to one side of the retaining sleeve. One end of the long rod 14 is connected to a long shaft 15 through a rotating shaft. One end of the long shaft 15 is connected through a limiting block 16. The limiting block 16 is fixedly connected to the top of the cooling pipe 19. A ring 18 is connected to one side of the long shaft 15 through a connecting rod 17. The connecting rod 17 is N-shaped. One side of the top of the connecting rod 17 is connected to the long shaft 15, and one side of the bottom of the connecting rod 17 is connected to the ring 18.

[0030] The bottom of cooling pipe 19 is connected to the top of tank 1. Water vapor generated during epoxy resin heating rises to cooling pipe 19, where it is cooled. A ring 18 is slidably disposed inside cooling pipe 19, its size matching the internal dimensions of cooling pipe 19. Ring 18 effectively cleans the inner wall of cooling pipe 19. Water outlet pipes 20 are connected to both sides of the bottom of cooling pipe 19, positioned at the top of water tank 5. A cooling assembly is fitted onto the outside of cooling pipe 19, containing a coolant pipe. Inlet and outlet pipes are connected to both sides of the cooling assembly, enabling coolant circulation and improving the cooling effect of cooling pipe 19. The inner wall of the outlet pipe 20... A baffle is fixedly connected to one side of the water outlet pipe 20, and a spring is fixedly connected to the top of the baffle. The top of the spring abuts against a slider 21. A moving block is fixedly connected to one side of the slider 21. A groove for the moving block to slide is opened on the inner wall of the water outlet pipe 20. An arc-shaped block is fixedly connected to the top of the slider 21. During the movement, the ring 18 squeezes the arc-shaped block, causing the slider 21 to descend in the water outlet pipe 20. A rectangular groove is opened on the surface of the slider 21. A circular plate 22 is rotatably connected to the inner wall of the water outlet pipe 20. The bottom of the inner wall of the rectangular groove of the slider 21 abuts against the bottom of the circular plate 22. When the slider 21 descends, the bottom of the circular plate 22 does not abut against the rectangular groove of the slider 21. The circular plate 22 begins to deflect, and the water cleaned by the ring 18 can be discharged from the water outlet pipe 20.

[0031] The implementation principle of the epoxy resin preheating device in this embodiment is as follows: When using the epoxy resin preheating device, firstly, the epoxy resin is poured into the tank 1 through the feed pipe, the power supply of the heating spiral coil 2 is turned on, the heating spiral coil 2 starts to heat, the heat generated inside the device heats the epoxy resin, the drive motor 7 is started, the drive motor 7 drives the central shaft 6 to start rotating, and the spiral blades 8 in the limiting tube 9 transport the epoxy resin at the bottom to the top for circulation, so that the epoxy resin can be heated evenly.

[0032] The water vapor generated during the heating of the epoxy resin moves upward to the cooling pipe 19, and the cooling component outside the cooling pipe 19 cools the water vapor.

[0033] The small gear 10, which is sleeved on the outside of the central shaft 6, meshes with the large gear 11. The large gear 11 drives the disc 12 to rotate. The disc 12 drives the long rod 14, which is sleeved on the outside of the retaining shaft 13, to start to deflect. The long shaft 15, which is connected to the long rod 14, reciprocates under the restriction of the limiting block 16. The long shaft 15 drives the ring 18 to slide inside the cooling pipe 19 through the connecting rod 17. The ring 18 cleans the water remaining inside the cooling pipe 19.

[0034] As the ring 18 moves, it squeezes the arc-shaped block, causing the slider 21 to descend inside the water outlet pipe 20. At this time, the bottom of the circular plate 22 does not contact the rectangular groove of the slider 21, and the circular plate 22 begins to deflect. The water cleaned by the ring 18 falls from the water outlet pipe 20 into the water tank 5 for collection.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
