[0027] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working methods. Figures 1 to 4 As shown, see the following description for details:
[0028] As a preferred embodiment, an adjusting screw 12 is passed through the central position of the oven 1 near the side of the mounting plate 11, and the end of the adjusting screw 12 is rotatably connected to the middle of the mounting plate 11; further, by rotating the adjusting screw 12, the mounting plate 11 can be driven to move left and right in the oven 1, thereby adjusting the distance between the first clamping plate 13 and the second clamping plate 14, thereby facilitating the clamping and fixation of rubber rollers 20 of different specifications.
[0029] As a preferred embodiment, drive gears 9 are evenly arranged on one side of the oven 1 close to the first clamping disc 13, and the drive gears 9 are meshed with each other. The drive gears 9 are fixedly connected to the first clamping disc 13 through central shafts. Further, the rotation of the drive gears 9 can drive the first clamping disc 13 to rotate, that is, the clamped rubber roller 20 rotates self-rotationally, so that the rubber roller 20 is heated more evenly in all directions.
[0030] As a preferred embodiment, a drive motor 8 is fixed on the side wall of the oven 1 through a mounting bracket 7, and a driving gear 21 is installed at the output end of the drive motor 8 through a rotating shaft. The driving gear 21 is meshed with one of the drive gears 9. Further, when the drive motor 8 works, it drives the driving gear 21 to rotate, and through the gear transmission effect, it drives multiple drive gears 9 to rotate synchronously, that is, the first clamping disc 13 rotates synchronously, and the design is more reasonable.
[0031] As a preferred embodiment, air collecting hoppers 401 are evenly arranged at the top inside the oven 1, and the tops of the air collecting hoppers 401 are connected to the return air pipe 4 through branch pipes.

The second clamping disc 14 is rotatably connected to the mounting plate 11 through a rotating shaft. Further, the "C" shape design and the same height make the mounting plate 11 can only move left and right in the oven 1, and cannot tilt or shake, and the fixing effect on the rubber roller 20 is better.

Further, the fixing plate 22 can抵住 the end of the rubber roller 20 under the action of the spring buffer column 23 to realize the preliminary fixing of the rubber roller 20, and the installation is more convenient.
[0034] The working process of the present utility model is as follows:
[0035] It should be noted that there is an error in the original text of . "抵住" should be "abut against". The corrected translation is: Further, the fixing plate 22 can abut against the end of the rubber roller 20 under the action of the spring buffer column 23 to realize the preliminary fixing of the rubber roller 20, and the installation is more convenient.When in use, first, according to the specifications of the rubber roller 20, rotate the adjusting screw 12 to move the mounting plate 11 in the oven 1, adjust the distance between the first clamping plate 13 and the second clamping plate 14, and then install the rubber roller 20 between the first clamping plate 13 and the second clamping plate 14. At this time, the fixing plate 22 can be pressed against the end of the rubber roller 20 under the action of the spring buffer column 23, and then continue to rotate the adjusting screw 12 to make the clamping and fixing more stable. During drying, the air pump 2 passes the outside air into the primary preheating pipe 15, and the air passes through the primary preheating pipe 15 and the secondary preheating pipe 15. After the heat pipe 18 is preheated, the air enters the oven 1 through the air distribution pipe 16 of the air distribution pipe 16, and contacts the rubber roller 20 after secondary heating by the electric heating network 19 to achieve hot air drying. The hot air after use can be discharged from the air collecting hopper 401 and returned to the air pump 2 through the return air pipe 4 to achieve hot air recycling. During drying, the drive motor 8 works, driving the driving gear 21 to rotate, and driving the multiple transmission gears 9 to rotate synchronously through the gear transmission action, that is, the first chuck 13 rotates synchronously, driving the rubber roller 20 to rotate, so that the rubber roller 20 is heated more evenly in all directions.
[0036] Finally: The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
