Compared with the prior art, the transmission belt 216 of the present invention restrains all the second gears 214 on the same central disc 21, thereby ensuring that all the drying cylinders 22 on the same central disc 21 can rotate at the same time.
Referring to fig. 1 and 2: the drying part 2 further comprises a linear moving assembly 28, the linear moving assembly 28 is fixedly arranged outside the box body 1, and the output end of the linear moving assembly 28 can drive the square plate 24 to move along the vertical direction.
During normal operation, the servo motor 26 operates to drive the middle pivot 25 to rotate, the middle pivot 25 drives all the drying cylinders 22 on the same central tray 21 to rotate through the first gear 211, at this time, the paper is firstly contacted by two adjacent drying cylinders 22 when entering the drying section 2, then leaves from the upper part of the third drying cylinder 22 and the lower part of the latter, and then the linear moving assembly 28 is started, the output end of the linear moving assembly 28 drives the square plate 24 to move along the vertical direction, the square plates 24 in a plurality of drying sections 2 move to different positions along the vertical direction under the operation of different linear moving assemblies 28, so that the moving tracks of the paper passing through the plurality of drying sections 2 are different, compared with the prior art, the linear moving assembly 28 of the present invention enables the position of the central tray 21 after moving along the vertical direction to be locked, and thus the vertical height of the moved drying section 2 is prevented from being changed randomly.
The above examples, which are intended to represent only one or more embodiments of the present invention, are described in greater detail and with greater particularity, and are not to be construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
