Description

Technical Field

[0001] The utility model relates to the technical field of gravure rollers, in particular to a split gravure roller which can be quickly disassembled and assembled. Background Art

[0002] The gravure roller is a commonly used coating production jig that can apply the coating smoothly and evenly on the product. It is suitable for coating production of various coating processes such as direct gravure coating, reverse gravure coating, reverse roller coating, etc. The main parameters of the gravure roller include mesh number and mesh depth. The mesh number is a measure of the particle size or fineness of the material, which refers to the number of holes in the screen within a 1-inch (25.4 mm) line segment, which reflects the particle size of the material. The larger the mesh number, the finer the particles. The mesh depth on the surface of the gravure roller determines the amount of coating on the gravure roller. These parameters are related to the gravure roller manufacturing process, which not only affects the coating efficiency, but also directly determines the coating quality. The gravure rollers with the same parameters will produce different undesirable phenomena in the coating production of different processes. In order to ensure the coating quality, in coating production, especially in precision coating production, gravure rollers are generally special rollers, and different processes use gravure rollers with different parameters.

[0003] At present, in actual production and debugging, the solution for replacing the gravure roller is often to replace the entire gravure roller. The old gravure roller must be completely removed from the mounting seat, and the corresponding shaft parts such as bearings and nuts supporting the gravure roller must also be completely removed. A new gravure roller is needed for complete restoration, assembly and debugging, which greatly affects the progress of coating production.

[0004] Therefore, it is necessary to provide a split gravure roller that can be quickly disassembled and assembled to solve the above problems. Utility Model Content

The bearing seat 2 is installed at both ends of the roller assembly 1 so that the roller assembly 1 can rotate normally; wherein, the roller assembly 1 includes an inner shaft 11, a sleeve roller 12 and an expansion sleeve 13. The expansion sleeve 13 is sleeved on the inner shaft 11. Both ends of the inner shaft 11 are rotatably connected to the bearing seat 2, and both ends of the sleeve roller 12 are detachably connected to the inner shaft 11 through the expansion sleeve 13. By locking the adjusting screw in the expansion sleeve 13, the inner circle of the expansion sleeve 13 is reduced inward to hold the inner shaft tightly. 11, and the outer ring of the expansion sleeve 13 expands outward to press the sleeve roller 12, relying on the friction force to make the inner shaft 11 and the sleeve roller 12 rotate synchronously, thereby realizing coating production; in addition, the gravure roller adopts a split structure design of the inner shaft 11 and the sleeve roller 12, which is connected and fixed by the expansion sleeve 13, so that the sleeve roller 12 can be quickly replaced, wherein the roller surface of the sleeve roller 12 is provided with mesh holes, and the number of holes and depths of the mesh holes of different sleeve rollers 12 are different, thereby realizing the rapid replacement of gravure rollers with different parameters, avoiding the disassembly of the entire gravure roller, simple operation, rapid replacement, and greatly improving production efficiency.

[0029] In addition, the bearing seat 2 includes a first bearing seat 21 and a second bearing seat 22, and the first bearing seat 21 and the second bearing seat 22 are detachably connected to the two ends of the inner shaft 11, and mounting flanges 4 are respectively provided on the first bearing seat 21 and the second bearing seat 22, so that the gravure roller can be fixedly installed on the wall panel of the coating machine through the mounting flanges 4.

When the expansion sleeve 13 is used, the inner ring 131 is sleeved on the inner shaft 11, and the outer ring 132 is connected to the inner wall of the sleeve roller 12. At the same time, a plurality of expansion holes 135 are provided on the tapered ring 133, and the locking screw 134 is locked in the expansion hole 135. As the locking screw 134 is tightened, the inner ring 131 and the outer ring 132 are tightened. When the loose screw 134 is screwed in, the tapered ring 133 will squeeze the inner ring 131 and the outer ring 132 to both sides, so that the inner ring 131 shrinks inward and holds the inner shaft 11 tightly, and the outer ring 132 expands outward and presses the sleeve roller 12 tightly, and the inner shaft 11 and the sleeve roller 12 rotate synchronously by relying on friction; when replacing the sleeve roller 12 with other parameters, the anti-loosening screw 134 of the expansion sleeve 13 is loosened, the inner ring 131 will expand and no longer hold the inner shaft 11, and the outer ring 132 will shrink and no longer press the sleeve roller 12 tightly.

[0032] Specifically, the transmission assembly 3 includes a transmission shaft 31, a synchronous pulley 32 and a rotating bearing 33, wherein the synchronous pulley 32 can be connected to the transmission shaft 31 by a key connection, so that the synchronous pulley 32 is fixed to the outer end of the transmission shaft 31, so that the rotary motion of the synchronous pulley 32 can be transmitted to the transmission shaft 31 under the action of the key, and at the same time, the inner end of the transmission shaft 31 and the inner shaft 11 can be connected and transmitted by a slot. Specifically, the inner end of the transmission shaft 31 is provided with a groove, and one end of the inner shaft 11 is provided with a The protrusion is clamped in the groove, so that the transmission shaft 31 can drive the inner shaft 11 to rotate synchronously, and the roller body can rotate stably; at the same time, the two ends of the transmission shaft 31 are rotatably connected with the first bearing seat 21 through the rotating bearing 33, wherein the external power source can be a motor, and the output end of the motor drives the synchronous pulley 32 to rotate through the synchronous belt, and the synchronous pulley 32 drives the transmission shaft 31 to rotate, and the transmission shaft 31 then transmits the power torque to the inner shaft 11, so as to realize the rotation of the inner shaft 11, thereby ensuring the normal rotation of the gravure roller.

[0033] Specifically, bearings 111 and fixings 112 are provided at both ends of the inner shaft 11. The inner shaft 11 is rotatably connected to the bearing seat 2 through the bearing 111. At the same time, the bearing 111 is connected to the fixing 112. The fixing 112 is provided with screw holes.
