All springs 386 are located inside the mounting groove 383. All levers 387 are slidably connected to the interior of the guide groove 384. The bottom surfaces of all locking blocks 385 are angled. All locking blocks 385 are slidably connected to the interior of the locking groove 382. Support columns 21 are securely fixed to the fixed platform 1, providing support for the lifting assembly 2. Connecting plates 22 connect two support columns 21, enhancing the overall structural stability and serving as a mounting platform for the first motor 23. Threaded rods 24 are connected to the first motor 23, rotating to drive the mounting plate 26 in lifting motion. Guide rods 25 are fixed to the top of the support columns 21, providing guidance for the mounting plate 26 and ensuring that the mounting plate 26 can only slide up and down. Mounting plate 26 is threadedly connected to threaded rod 24 and is restricted to sliding up and down by guide rod 25. It is used to mount roller assembly 3 and feed assembly 4. Roller mounting bracket 33 is fixed on mounting plate 26, providing a mounting platform for drive disk 34 and roller body 37. Drive disk 34 is connected to roller body 37 through connector 36. When rotating, it drives roller body 37 to rotate. Driven gear 35 is fixed on drive disk 34 near the end of drive gear 32 and meshes with drive gear 32 to realize power transmission.

Workers can send commands through remote control device to control the start, stop and speed adjustment of these motors.This allows for convenient and precise adjustment of the roller frame.

[0021] Working principle: When the first motor 23 starts, it drives the threaded rod 24 to rotate. Since the mounting plate 26 is threadedly connected to the threaded rod 24 and is restricted to sliding up and down by the guide rod 25, the rotation of the threaded rod 24 will drive the mounting plate 26 to move up and down along the guide rod 25. The roller assembly 3 and the feed assembly 4 set on the top surface of the mounting plate 26 together complete the rotation and feeding of the product. In the roller assembly 3, the second motor 31 is fixed on the mounting plate 26, and its output shaft is connected to the drive gear 32 through a coupling. When the second motor 31 starts, the drive gear 32 rotates accordingly. When the drive gear 32 rotates, the driven gear 35 meshes with the driven gear 35. The driven gear 35 is fixed on the drive disk 34 near the end of the drive gear 32. Therefore, the rotation of the drive gear 32 will drive the driven gear 35 and the drive disk 34 to rotate. The drive disk 34 is connected to the roller body 37 through the connector 36. The connecting groove 381 on the connector 36 cooperates with the connecting shafts on both sides of the roller body 37. The locking block 385 inside the connecting shaft is locked into the locking groove 382 of the connector 36 under the action of the spring 386, realizing a stable connection between the roller body 37 and the connector 36. When the drive disk 34 rotates, it... Connector 36 drives roller body 37 to rotate, thereby realizing the product's rotation function. Feed assembly 4 is located on one side of roller assembly 3, including feed motor, fixed frame and feed wheel. Feed motor drives feed wheel to rotate, and the product's feeding motion is realized through friction between feed wheel and product. The entire device is controlled by remote control, allowing workers to easily and precisely adjust the roller frame to ensure equal distance between product and induction coil, meeting the requirement of uniform heating. When the connecting shaft of roller body 37 is inserted into the connecting groove 381 of connector 36, the angled structure of locking block 385 will be connected first. The inner wall of groove 381 is compressed, and spring 386 is compressed until the locking block 385 moves to the position of locking groove 382. The elastic force of spring 386 causes the locking block 385 to pop out and lock into locking groove 382, ​​thereby realizing a stable connection between roller body 37 and connector 36. When it is necessary to disassemble roller body 37, simply move lever 387 to make locking block 385 exit from locking groove 382, ​​and roller body 37 can be easily removed from connector 36. When roller body 37 is damaged by product and needs to be replaced, the connection component 38 facilitates the replacement of roller body 37.
