Specific implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The present invention provides a technical solution: as Figure 1 - Figure 4 shown, in this embodiment, a melting cylinder constant temperature device includes a first constant temperature cover 1. A heat dissipation fan 4 is fixedly installed in the middle of one side of the first constant temperature cover 1. A protective box 12 is fixedly connected to one side of the heat dissipation fan 4. A bidirectional motor 17 is fixedly installed in the middle of one side of the heat dissipation fan 4. One side of the output end of the bidirectional motor 17 is drivingly connected to a worm 19. A turbine 18 is engaged with one side of the outer wall of the worm 19. The lower end of the turbine 18 is fixedly connected to a special-shaped rotating frame 20. The lower end of the special-shaped rotating frame 20 is rotatably connected to a swing rod 21. The middle of the swing rod 21 is slidably connected to a limit column 26. One end of the limit column 26 is fixedly connected to the inner wall of the protective box 12. One side of the inner wall of the swing rod 21 is slidably connected to a connecting column 22. The lower end of the connecting column 22 is rotatably connected to an L-shaped sliding frame 23. The upper end of the L-shaped sliding frame 23 is rotatably connected to a plurality of connecting blocks 24. One side of each of the plurality of connecting blocks 24 is fixedly connected to a guide vane 11. One end of each of the plurality of guide vanes 11 is respectively rotatably connected to one side of the inner wall of the protective box 12. When the bidirectional motor 17 is turned on, the heat dissipation fan 4 rotates to blow the gas outside the first constant temperature cover 1 into the first constant temperature cover 1. Then, through the cooperation of the worm 19 and the turbine 18, the horizontal power is converted into vertical power. The special-shaped rotating frame 20 swings the swing rod 21 along the limit column 26. The L-shaped sliding frame 23 slides in the L-shaped sliding groove 25. When sliding, the connecting block 24 is pulled, so that the guide vane 11 rotates in the protective box 12, adjusting the blowing direction of the heat dissipation fan 4, ensuring that the hot air is effectively discharged, improving the cooling efficiency, and quickly realizing the constant temperature of the melting cylinder.

[0021] As Figure 4 shown, an L-shaped sliding groove 25 is opened on one side of the inner wall of the protective box 12 and close to the edge. The inner wall of the L-shaped sliding groove 25 is slidably connected to the outer wall of the L-shaped sliding frame 23. The sliding direction of the L-shaped sliding frame 23 is restricted by the L-shaped sliding groove 25.

[0022] AsFigure 1 and Figure 4 As shown in Figure 4 , a dust-proof cover 16 is fixedly installed on one side of the cooling fan 4. The dust-proof cover 16 can filter out the dust in the air, thereby increasing the service life of the cooling fan 4.

[0023] As Figure 2 and Figure 3 shown, a hinge 13 is fixedly connected to one side of the constant temperature cover 1. One side of the hinge 13 is fixedly connected to the constant temperature cover 2 3. A buckle 5 is fixedly installed on one side of the constant temperature cover 2 3. A fixed clamping block 6 is fixedly connected to one side of the constant temperature cover 1. The hinge 13, the buckle 5 and the fixed clamping block 6 facilitate the installation of the constant temperature cover 1 and the constant temperature cover 2 3 on the melting cylinder.

[0024] As Figure 1 – Figure 3 shown, a threaded rod 2 is threadedly connected to the outer wall of the constant temperature cover 1. A limiting block 8 is fixedly connected to one side of the inner wall of the constant temperature cover 1. A guiding groove 10 is formed on one side of the limiting block 8. One end of the threaded rod 2 is fixedly connected to a clamping block 9. The outer wall of the clamping block 9 is slidably connected to the inner wall of the guiding groove 10. By rotating the four threaded rods 2, the four clamping blocks 9 are respectively moved in the four guiding grooves 10, so that the constant temperature cover 1 and the constant temperature cover 2 3 can be installed on melting cylinders of different sizes, improving the versatility of the constant temperature device. The structures inside the constant temperature cover 1 and the constant temperature cover 2 3 are the same.

[0025] As Figure 3 shown, an inner container 14 is fixedly connected to the inner wall of the constant temperature cover 2 3. A temperature sensor 7 is fixedly installed inside the inner container 14. A heating device 15 is arranged between the inner container 14 and the constant temperature cover 2 3. Through the cooperation of the temperature sensor 7, the heating device 15 and the cooling fan 4, the melting cylinder can be kept at a constant temperature all the time.

[0026] The present utility model provides a melting cylinder constant temperature device, and the specific working principle is as follows:

[0027] When maintaining the constant temperature of the melting cylinder, first rotate the four threaded rods 2 to move the four clamping blocks 9 respectively within the four guide grooves 10, adjust the clamping blocks 9 to a suitable size for the melting cylinder, place the melting cylinder between the constant temperature cover one 1 and the constant temperature cover two 3, and then use the buckle 5 and the fixed clamping block 6 to fix the constant temperature cover one 1 and the constant temperature cover two 3 on the melting cylinder. When the melting cylinder is in use, the temperature sensors 7 within the constant temperature cover one 1 and the constant temperature cover two 3 measure the temperature. When the temperature is low, turn on the heating device 15 for heating. When the temperature is high, turn on the bidirectional motor 17 to make the cooling fan 4 rotate, blowing the gas outside the constant temperature cover one 1 into the constant temperature cover one 1. Then, through the cooperation of the worm 19 and the turbine 18, convert the horizontal power into vertical power. The special-shaped rotating frame 20 swings the swing rod 21 along the limit post 26, and the L-shaped sliding frame 23 slides within the L-shaped sliding groove 25. When sliding, it pulls the connecting block 24, causing the guide vane 11 to rotate within the protection box 12, adjusting the blowing direction of the cooling fan 4 to ensure that the hot air is effectively discharged, thereby achieving the constant temperature state of the melting cylinder.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
