Description

Rotatable fixing device Technical Field The utility model belongs to the technical field of coating machines, and particularly relates to a rotatable fixing device. Background The coater is a common device for coating paint on paper cloth materials, a plurality of adjacent roll shafts are mutually attached, the paint is transferred to a middle roll shaft through an outer roll shaft, the roll shaft positioned in the middle is used for clamping the paper cloth materials in the middle, and the transferred paint and other materials are coated on the paper cloth materials. Patent number 202222845481.9, in the public description that publication day is 2023 3 month 24 day, a coating machine compression roller fixed knot constructs is disclosed, belong to coating machine technical field, including lifting support subassembly, fixed subassembly and compression roller, two electric telescopic handle sets up the symmetry setting in the backup pad in the lifting support subassembly, two electric telescopic handle telescopic end fixedly connected with holding ring is used for adjusting holding ring's vertical distance and is convenient for install the compression roller, fixed subassembly includes the mount pad of symmetry setting in the backup pad both sides, the mount pad internal rotation is connected with adjusting screw, adjusting screw equal threaded connection has the joint piece, joint piece one side joint has the compression roller, compress tightly the compression roller in the holding ring inner wall with joint ring joint clamp fastening compression roller in the fixed subassembly then, adjusting screw counter-rotating during the needs change, loose both sides joint piece is taken out the joint ring from the holding ring inner wall, dismantle the compression roller, the inconvenient problem of compression roller dismantlement has been solved, the compression roller is fixed inconvenient. In the prior art, because the pressure demands of different paper cloth and paint on the roll shafts are different, the heights of different roll shafts are required to be adjusted, and thus, a device for lifting is required to be installed on a shell of the whole equipment, the space of a device for clamping and fixing the roll shafts is smaller, but the roll shafts themselves have larger mass, the clamping strength is required, the clamping devices are generally larger, and therefore, the roll shafts are very inconvenient to install, especially the bottom roll shafts are very difficult to install. Disclosure of utility model The utility model aims to provide a rotatable fixing device with small overall occupied volume and good clamping effect. In order to achieve the purpose, the rotatable fixing device comprises a base, wherein a claw is arranged on the base, a control piece for controlling the claw to rotate is arranged on the base, the base is gun-shaped, an arc groove is formed in the base, and a roll shaft end is arranged between the claw and the arc groove. The claw is hinged on the base, a central shaft penetrating the claw is arranged on the base, a side plate is arranged at the bottom of the base, and the claw is located between the side plates. The control piece is including setting up the base in curb plate bottom, be equipped with the lead screw in the base, the jack catch is equipped with the spout in being located one side between the curb plate, be equipped with the slide bar in the spout, the lead screw runs through the slide bar and with slide bar threaded connection. Bearings matched with the screw rods are arranged in the base and the base. The bottom of the screw rod is positioned at the outer side of the base. The base is provided with a groove.
