Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production equipment, in particular to a reinforcement device and a calender. Background Art
[0002] The upper and lower embossing rollers of the calender are equipped with rotating water jackets at the transmission ends. The outer shell of the rotating water jacket is fixed with 8 M12 hexagonal bolts. However, as the thickness of the produced glass becomes thinner and thinner, the friction resistance generated when the upper and lower embossing rollers rotate is also increasing, which makes the torque of the 8 M12 hexagonal bolts become larger and larger. Due to the above reasons, there have been many incidents of partial breaking of the fixing bolts of the rotating water jacket at the transmission end of the embossing roller. Fortunately, they were discovered in time and effectively handled without affecting production. If the fixing bolts of the rotating water jacket are not discovered in time before they are all broken, the rotating water jacket will fall off, resulting in the inability to transmit the transmission torque and splashing cooling water everywhere, which will eventually cause the calender to shut down and change the machine, resulting in great economic losses.
[0003] Therefore, there is an urgent need for a reinforcement device and a calender to solve the above problems. Utility Model Content

Among them, the first limiter 1 is welded to the bearing seat of the pressure roller, and the first limiter 1 and the bearing seat form a limit groove, and the depth direction of the limit groove is the first direction.

The first locking nut 4 abuts against the side of the second limiter 2 facing the bearing seat to fix the position of the reinforcement rod 3 relative to the limit through hole, and prevent the reinforcement rod 3 from moving out of the limit groove in the limit through hole. The reinforcement rod 3 is subjected to a certain torque, so that the torque borne by the fixing member 800 of the rotating water jacket can be reduced to prevent the fixing member 800 from breaking.
[0033] Optionally, the reinforcement rod 3 extends along a first direction, which is parallel to the axial direction of the inner ring of the bearing seat.
[0034] Optionally, an internal thread is provided on the side wall of the limiting groove, and the internal thread cooperates with the external thread so that the reinforcement rod 3 is screwed into the limiting groove to ensure a firm connection between the two and prevent the reinforcement rod 3 from escaping from the limiting groove.
