[0016] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] Depend on Figures 1 to 5 The present invention includes a heating box 1 with an open end, a support base 2 fixedly installed at the bottom of the heating box 1, electric heating tubes 3 evenly spaced in a ring inside the heating box 1, a horizontally adjustable sealing cover 4 at the opening of the heating box 1, a sleeve rod 5 rotatably installed in the middle of the sealing cover 4 inside the heating box 1, a fixing block 6 fixedly installed at one end of the top of the heating box 1, an n-shaped plate 7 installed between the two sides of the sealing cover 4, two sliding rods 8 movably inserted into the lower part of the fixing block 6, one end of each sliding rod 8 being fixedly connected to the n-shaped plate 7, a threaded shaft 9 threadedly connected to the middle of the fixing block 6, a motor A10 installed on one side of the upper part of the n-shaped plate 7, the output end of the motor A10 being fixedly connected to one end of the threaded shaft 9; a transmission gear ring 20 fixedly installed on the surface of the sleeve rod 5 on one side of the sealing cover 4, a motor B22 installed on one side of the sealing cover 4, and a gear 23 fixedly installed at the output end of the motor B22, meshing with the transmission gear ring 20, thereby effectively driving the sleeve rod 5 to rotate;

[0018] By starting the motor B22, the gear 23 drives the transmission gear ring 20, which in turn drives the sleeve 5 to rotate. The rotation of the sleeve 5 will cause the shaft seal on its surface to rotate. Then, by turning on the electric heating tube 3, the rotating shaft seal can be heated evenly.

[0019] This shaft seal heating device can perform batch fixing and uniform heating of shaft seals, and facilitate convenient assembly and disassembly of shaft seals, thereby effectively improving the heating efficiency of shaft seals. At the same time, this shaft seal heating device has good sealing performance, which improves the heating effect and reduces energy consumption. Furthermore, this shaft seal heating device has a simple structural design, is convenient to use and operate, and provides stable and reliable heating treatment. Its performance can meet the needs of shaft seal processing.

[0020] The sleeve rod 5 has two symmetrically arranged transverse grooves 11 on its surface inside the heating box 1. The middle part of the sleeve rod 5 has an inner cavity 12 that communicates with the two transverse grooves 11. Each of the two transverse grooves 11 has a clamping strip 13 inside. A bidirectional threaded shaft 15 is rotatably installed inside the inner cavity 12. Both sides of the bidirectional threaded shaft 15 are threadedly connected to moving blocks 16. Both ends of the moving blocks 16 are rotatably connected to the two clamping strips 13 with two inclined connecting rods 17. One end of the bidirectional threaded shaft 15 extends to one end of the sleeve rod 5 and is fixedly connected to an adjusting wheel A18. A retaining ring 19 for limiting the shaft seal is fixedly installed on the surface of the sleeve rod 5, so that the shaft seal can be installed in batches.

[0021] By batching the shaft seals onto the surface of the sleeve rod 5, and then rotating the bidirectional threaded shaft 15 by adjusting wheel A18, the rotation of the bidirectional threaded shaft 15 will cause the two moving blocks 16 to move relative to each other. The relatively moving moving blocks 16 will push the clamping strip 13 out of the transverse groove 11 through the linkage rod 17. Finally, the two clamping strips 13 will clamp and open the batch of shaft seals on the surface of the sleeve rod 5 from the inside and fix them.

[0022] Then, by starting the motor A10, the threaded shaft 9 is rotated. The rotation of the threaded shaft 9 will cause the threaded feed movement on the fixed block 6, which will drive the n-shaped plate 7 to move. The movement of the n-shaped plate 7 will drive the two slide rods 8 to move on the fixed block 6 and drive the sealing cover 4 and the sleeve rod 5 to move towards the inside of the heating box 1 until the sealing cover 4 seals the opening of the heating box 1.

[0023] A connecting shaft 24 is fixedly installed at the middle of both ends of the sealing cover 4. The two connecting shafts 24 are rotatably connected to both ends of the n-shaped plate 7. A worm gear 25 is fixedly installed at the outer end of the two connecting shafts 24. A worm 26 that meshes with the worm gear 25 is rotatably installed at both ends of the n-shaped plate 7. A sprocket 27 is fixedly installed at the top of the two worms 26. A chain 28 is installed between the two sprockets 27. An adjusting wheel B29 is fixedly installed at the top of one of the sprockets 27. An inverted L-shaped plate 30 for limiting and blocking the sealing cover 4 is fixedly installed on one side of the n-shaped plate 7, so that the sealing cover 4 and the sleeve rod 5 can be tilted and adjusted to facilitate the disassembly of the shaft seal after batch heating.

[0024] After the batch of shaft seals on the surface of sleeve rod 5 have been heated, sleeve rod 5 is removed from the heating box 1. Then, one of the sprockets 27 is rotated by adjusting wheel B29, and the other sprocket 27 is rotated synchronously by sprocket 27. The rotation of the two sprockets 27 will cause the two worm gears 26 to rotate, and the rotation of the two worm gears 26 will drive the two worm wheels 25 to rotate. The rotation of the two worm wheels 25 will drive the sealing cover 4 and sleeve rod 5 to tilt through the two connecting shafts 24. Then, the two clamping strips 13 are adjusted so that the two clamping strips 13 are stored inside the transverse groove 11, and then the shaft seal on the surface of sleeve rod 5 will automatically slide off.
