Description

Technical Field

[0001] The utility model relates to the technical field of papermaking drying cylinders, in particular to a papermaking drying cylinder maintenance device. Background Art

[0002] Papermaking enterprises generally use drying cylinders with a diameter of about φ1.2 to φ5 meters to dry wet paper webs. The drying cylinder is supported by double-row spherical roller bearings for high-speed operation. The bearing support position of the dryer shaft head of medium and low-speed paper machines was originally designed as a cylindrical surface. The double-row spherical roller bearings are K series with tapered holes, and are fixed to the shaft with locking bolts through a withdrawal sleeve (or disassembly sleeve) with the same tapered (usually 1:12 taper, and also 1:30 taper).

[0003] This design ensures that the bearing can withstand heavy radial loads (the drying cylinder weighs more than several tons). At the same time, due to the certain taper of the inner hole of the inner ring of the bearing, a certain axial load will also be generated. The bearing removal sleeve operates under heavy load for a long time, and there will be cumulative processing errors in the removal sleeve and the shaft head during the machining process.

[0004] After long-term high-speed operation, the nut will inevitably become loose, and the loose withdrawal sleeve will cause the shaft head to be worn or cause an accident. Most of the shaft heads of the drying cylinders are cast iron parts, and most of the withdrawal sleeves are carbon steel parts. The hardness of the withdrawal sleeve is slightly greater than that of the shaft head. After the withdrawal sleeve is loose, the bearing and the shaft head are not concentric, and the inner ring will shake violently. Strong squeezing of the withdrawal sleeve will cut the shaft head like a blade, resulting in severe wear. In the worst case, it will cause the shaft head to break. It takes at least 5 days to stop the machine to replace the drying cylinder, which is labor-intensive and costly.

[0005] There is also a certain amount of wear on the surface of the drying cylinder, but the previous maintenance equipment has a limited range of action, making it difficult to repair both the drying cylinder body and the rotating shaft. There is also a lack of corresponding clamping methods to facilitate maintenance operations on the drying cylinder body and the rotating shaft.

[0006] Now, a new type of papermaking drying cylinder maintenance equipment is proposed to solve the above problems. Utility Model Content

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a papermaking drying cylinder maintenance equipment, comprising a base plate and a movable chamber, movable chambers are horizontally arranged at both ends of the top of the base plate, and slide plates are longitudinally inserted on both sides of the inside of the movable chamber, positioning bolts are meshed and connected on both sides of the slide plate, a vertical plate is vertically welded to the top of the slide plate, a first motor is installed at the center of one side of the vertical plate, and the output shaft of the first motor passes through the vertical plate and is fixed with a vertical plate, a third motor is installed above the outside of the vertical plate, and a screw rod is movably connected between the top and bottom ends of the third motor, shaft sleeves are sleeved above and below the screw rod, and a fitting plate is fixed on one side of the shaft sleeve through the vertical plate, a frame plate is installed between one end of the top of the vertical plate, and a crossbeam is arranged between one side above the frame plate.

[0009] Preferably, threads are carved on the inner side of the shaft sleeve, and the shaft sleeve and the bonding plate are in the same horizontal plane.

[0010] Preferably, the vertical plate can rotate in situ on one side of the vertical plate, and the vertical plate and the screw rod are in the same vertical plane.

[0011] Preferably, a notch is provided at the center of the mounting plate, and balls are movably embedded in the top and bottom ends of the notch, a second motor is installed on both sides of the beam, a transmission gear is fixedly connected to the output shaft of the second motor, threaded cylinders are movably connected on both sides of the top of the beam, and a linkage gear is welded to the bottom end of the outside of the threaded cylinder, a screw is longitudinally connected between the threaded cylinder and the linkage gear, and a bracket is fixed to the bottom of the screw, and a brush roller is installed between one side of the bracket.

[0012] Preferably, the bottom of the transmission gear is movably connected to the crossbeam, and the linkage gear is meshed with one side of the transmission gear.

[0013] Preferably, the screw rod can be vertically lifted and lowered under the restriction of the bracket and the brush roller, and the bracket is symmetrically installed on both sides of the brush roller.

[0014] Preferably, a slide rail is welded transversely to the front end of the crossbeam, and a sleeve is movably connected inside the slide rail, a plug rod is longitudinally inserted in the sleeve, a fastening bolt is movably connected between the sleeve and one end of the plug rod, a mounting block is fixed to the bottom of the plug rod, and a grinding appliance is movably connected to the rear of the mounting block, a storage groove is transversely installed at the center of the top of the base plate, and a protective frame is installed at the rear of the base plate.

[0015] Preferably, the grinding appliance can rotate horizontally inside the mounting block, and the insertion rod can slide up and down along the inner wall of the sleeve.

[0016] Compared with the prior art, the utility model has the following beneficial effects: the papermaking drying cylinder maintenance equipment can not only realize the rapid fixing of the drying cylinder assembly and the adjustment and cleaning of the roller shaft, but also realize the rapid grinding of the drying cylinder body;

[0017] (1) The vertical plate is fixed by passing the output shaft of the first motor through the vertical plate. The vertical plate can rotate in place under the control of the first motor, and then the third motor is turned on to continue rotating the screw rod in the vertical plate. The two sets of shaft sleeves on the outside of this object will also move in the opposite direction. The drying cylinder body or the shaft head on one side is clamped by the bonding plate, and the shaft head on the other side is thoroughly cleaned with kerosene and 1755 cleaning agent, and then the oil is burned off with oxyacetylene flame for degreasing treatment, followed by hand grinding and cleaning.

The φ195 gear assembly journal is used as the positioning reference. During this period, the upper positioning pin of the shaft head or the M14 fastening bolt is slowly tightened to squeeze out the excess repair agent from the φ10 process hole. In order to accelerate the curing time of the repair agent, a high-power lighting spotlight or oxyacetylene flame can be used to illuminate and bake it slowly to assist in heating. After 3 hours, remove the inner cone cast iron sleeve and assemble it on the frame cover to prevent oil leakage.

[0019] (2) By installing a brush roller between one side of the bracket and starting the second motor on both sides of the beam, the transmission gear connected to the object can mesh with the linkage gear on one side and make the threaded barrel inside it rotate in place. Since the bottom of the screw is connected to the brush roller through the bracket, the object can be forced to slide up and down along the threaded barrel, so as to achieve the purpose of lifting and cleaning the brush roller, making it convenient for the object to approach the outer wall of the drying cylinder to clean the residue and debris, and it does not hinder the installation and removal of the drying cylinder;

[0020] (3) By movably connecting the grinding appliance at the rear of the mounting block, the sleeve is translated left and right along the inner groove of the slide rail, and then the insertion rod is pulled up and down. The fastening bolts can be used to lock it to prevent the mounting block and the grinding appliance below from shaking, and force this mechanism to approach the surface in front of the drying cylinder for grinding, ensuring that the surface of the drying cylinder is flat enough for paper lamination and drying, and avoiding dirt remaining on the outer wall of the drying cylinder and affecting the quality of the paper after drying.
