[0003] The drying cylinder rotates under the support of the supporting wheel by the support ring, and the support ring and the cylinder body are padded with overfitting gaskets. The friction torque generated by the support ring and the cylinder body makes the support ring and the cylinder body rotate as a whole. The inventor found that relative sliding is easy to occur between the support ring and the cylinder body during rotation. Summary of the invention

[0004] The purpose of the utility model is to provide a drying cylinder additional resistance torque device, and the purpose to be achieved is to use a simple structure to achieve stable and reliable operation of the drying machine cylinder.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The additional resistance torque device of the drying cylinder includes a support seat, a pressure plate, a brake band and bolts, and is characterized in that: the number of the support seats is ≥ one group, and any group of the support seats is fixedly connected to the cylinder body of the drying cylinder, and any group of the support seats is symmetrically distributed on both sides of the support ring of the drying cylinder; bolts are installed on the support seat, and the bolts are fixedly connected to the pressure plate and the brake band; and the pressure plate and the brake band are pressed against the side of the support ring.

[0007] As an improvement of the present invention, the number of the support seats is four, six, eight or ten groups, and the support seats are evenly distributed on the cylinder body of the drying cylinder.

[0008] As an improvement of the utility model, a blocking plate is further provided; the blocking plate is fixedly connected to the support seat, and the blocking plate limits the bolts in the installation groove of the support seat.

[0009] As an improvement of the present utility model, the number of the mounting grooves of the support seat is 2.

[0010] Beneficial effects after adopting the above technical solution:

[0011] 1) A set of bolts are arranged on both sides of the support seat, and the pressure plate and the brake belt are adjusted by the bolts so that the pressure plate and the brake belt are pressed against the side of the support ring to provide additional torque to prevent the support ring from reversing.

[0012] 2) Support seats are evenly distributed on the circumference of the drying cylinder so that the additional torque is evenly distributed on the circumference of the drying cylinder, thereby improving the stability and reliability of the cylinder operation.

[0013] 3) The support seat has two mounting grooves, so that each pressure plate and brake band can receive the adjustment force of two bolts, so that the pressure plate and brake band are pressed more tightly and evenly against the side of the support ring, and the additional torque generated is more stable and reliable.
