[0001] The utility model relates to the technical field of resins, and particularly relates to a heat preservation device. Background Technique

[0002] Resin usually refers to an organic polymer that has a softening or melting range when heated, has a tendency to flow under the action of external force when softened, is solid, semi-solid at normal temperature, and sometimes can also be liquid. In a broad sense, any high molecular compound that can be used as a processing raw material for plastic products is called resin. Among them, waterborne epoxy curing agent is a water-soluble modified epoxy polyamine adduct curing agent with a new structure, uses water as a diluent, does not contain alcohol ether solvents or co-solvents, and does not contain acetic acid neutralizers.

[0003] At present, during the storage of waterborne epoxy curing agent, it is necessary to control its temperature to prevent it from curing, and a heat preservation device will be used. However, when some existing heat preservation devices are in use, due to the decrease in the temperature of the waterborne epoxy curing agent, its fluidity decreases. When some waterborne epoxy curing agent is heated to restore its storage temperature, it will cause uneven heating, and then some waterborne epoxy curing agent will solidify.

[0014] Preferably, a positioning ring is fixedly connected to the bottom of the top cover, a positioning groove matched with the positioning ring is formed inside the heat preservation barrel, and a sealing ring is arranged on the inner ring of the heat preservation barrel.

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

[0016] By arranging a heating component, the present utility model can detect the temperature of the materials inside the heat preservation barrel through a temperature sensor.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 As shown in the figure, a heat preservation device includes a top cover 1, and further includes: a heat preservation barrel 2 arranged at the bottom of the top cover 1, a PLC controller 3 arranged outside the heat preservation barrel 2. By setting the PLC controller 3, various electronic components inside the device can be controlled to operate in cooperation; a heating component 4 arranged inside the heat preservation barrel 2. Under the action of the heating component 4, the materials inside the heat preservation barrel 2 can be heated to keep the materials at a normal temperature. The heating component 4 includes a motor 41 fixedly connected to the bottom of the inner cavity of the heat preservation barrel 2. The output end of the motor 41 is fixedly connected with a transmission rod 42. Starting the motor 41, under the action of the motor 41, the transmission rod 42 can be driven to rotate. Then, when the transmission rod 42 rotates, a plurality of side rods 44 outside it can be driven to rotate. A first heating pipe 43 is arranged outside the transmission rod 42. Under the action of the first heating pipe 43, the materials around it can be heated. The side rod 44 is fixedly connected to the outside of the first heating pipe 43. Under the action of the transmission rod 42, the first heating pipe 43 can be driven to rotate. Then, when the first heating pipe 43 rotates, the side rod 44 can be driven to rotate, so that a plurality of side rods 44 can stir the materials inside the heat preservation barrel 2. A scraper 45 is arranged inside the heat preservation barrel 2. Under the action of the scraper 45 and the inclined plate 18, the materials inside the heat preservation barrel 2 can be fully stirred, so as to facilitate heating of the materials.

[0024] Refer to Figure 2 and Figure 3As shown, a second heating tube 5 is provided on the outer side of the side rod 44. Under the action of the second heating tube 5, the material at the side rod 44 can be heated. A sliding rod 6 is slidably connected inside the side rod 44. Under the action of the sliding rod 6, the inclined plate 18 and the scraping plate 45 can move to the designated positions, so that the inclined plate 18 can be closely attached to the inner wall of the heat preservation barrel 2.

[0025] A spring 7 is provided on the outer side of the sliding rod 6. Under the elastic force of the spring 7, the sliding rod 6 can slide inside the side rod 44, thereby adjusting the position of the inclined plate 18. One end of the spring 7 is welded to the front surface of the side rod 44. A rotating ball 8 is rotatably connected inside the side rod 44. When adjusting the position of the scraping plate 45, under the action of the rotating ball 8, the scraping plate 45 can be adjusted in angle, so that the inclined plate 18 can contact the inner wall of the heat preservation barrel 2.

[0026] A heating plate 9 is provided on the front surface of the scraping plate 45. By providing the heating plate 9, the material at the inclined plate 18 can be heated. One side of the heating plate 9 is provided with the inclined plate 18.

[0027] A fixing frame 10 is fixedly connected to the inner wall of the heat preservation barrel 2. By providing the fixing frame 10, the driving rod 42 can be kept stable when rotating. The bottom of the fixing frame 10 is rotatably connected to the top of the driving rod 42.

[0028] A heat preservation board 11 is provided inside the heat preservation barrel 2. By providing the heat preservation board 11, the material inside the heat preservation barrel 2 can be heat-preserved, thereby reducing the heat dissipation rate inside the material. A temperature sensor 12 is provided on the inner circle of the heat preservation board 11.

[0029] Reference Figure 1 and Figure 4 As shown, a connecting ring 13 is fixedly connected to the bottom of the top cover 1. Under the action of the connecting ring 13, the contact position between the top cover 1 and the heat preservation barrel 2 can be sealed. A through hole 14 is opened inside the connecting ring 13. Under the action of the through hole 14, it is convenient for the staff to connect the top cover 1 and the heat preservation barrel 2 through the positioning bolt.

[0030] A positioning ring 15 is fixedly connected to the bottom of the top cover 1. A positioning groove 16 matched with the positioning ring 15 is opened inside the heat preservation barrel 2. A sealing ring 17 is provided on the inner circle of the heat preservation barrel 2.

[0031] Working principle: When the staff performs heat preservation operation on the materials through the heat preservation barrel 2, the heat inside the materials gradually dissipates. Under the action of the temperature sensor 12, the temperature of the materials is monitored. When the temperature of the materials drops to a certain threshold, through the PLC controller 3, the motor 41 starts to work. Under the action of the motor 41, the transmission rod 42 can be driven to rotate. When the transmission rod 42 rotates, the side rod 44 can be driven to rotate, so that the first heating pipe 43 and the second heating pipe 5 start to rotate. At the same time, under the elastic force of the spring 7, the position of the sliding rod 6 can be adjusted, so that the sliding rod 6 can drive the scraper 45 to move, so that the inclined plate 18 can contact the inner wall of the heat preservation barrel 2. At the same time, under the action of the heating plate 9, the materials at the inclined plate 18 can be heated. At the same time, when the inclined plate 18 rotates, the materials adhering to the inner wall of the heat preservation barrel 2 can be scraped off, so that the materials inside the heat preservation barrel 2 can be fully stirred, so that the materials can be evenly heated through the first heating pipe 43, the second heating pipe 5 and the heating plate 9, preventing uneven heating during the heating process of the materials, and the temperature of some materials is too low, which is not conducive to their subsequent use.
