Description

Technical Field

[0001] The utility model belongs to the field of core shaft pressing equipment, in particular to a core shaft pressing device for a paper pressing roller. Background Art

[0002] The paper pressing roller includes a hollow cylindrical roller (with concave and convex patterns on it) and a core shaft for driving inserted into the cylinder. The two ends of the core shaft are protruding and connected to driving mechanisms such as rotating bearings and belts. The paper pressing roller core shaft pressing device is a device used to press the core shaft into the inner cylinder of the paper pressing roller.

[0003] The existing paper pressing roller core shaft pressing device does not have a good limiting structure and cannot effectively limit the cylindrical roller, which causes the core shaft to be easily misplaced during installation, making it inconvenient for operators to install, increasing the difficulty of installation, increasing the work intensity of operators, and reducing work efficiency.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0024] The utility model will now be further described in detail with reference to the accompanying drawings.

[0025] See also Figure 1-4 As shown, in this embodiment, a paper pressing roller core shaft pressing device is provided, comprising: a base 1, the base 1 is slidably matched with a movable seat 3 and a pressing seat 6, the base 1 is equipped with a limit seat 2 and a supporting sliding seat 5, and the base 1 is equipped with a first linear driving member 10 and a second linear driving member 11 connected to the movable seat 3 and the pressing seat 6, wherein the first linear driving member 10 and the second linear driving member 11 are electric slide rails or linear motors in the prior art;

[0026] Two arc-shaped clamping plates 4 are slidably fitted on the movable seat 3, a relative movement component 12 connected to the two arc-shaped clamping plates 4 is installed on the movable seat 3, a limiting opening 8 is opened on one side of the limit seat 2, a slideway 14 is provided on the supporting sliding seat 5, and a telescopic member 17 is installed between the supporting sliding seat 5 and the base 1, wherein the telescopic member 17 is an electric telescopic rod or a hydraulic telescopic rod in the prior art.

[0027] By setting two arc clamping plates 4 on the movable seat 3, the relatively movable assembly 12 can drive the two arc clamping plates 4 to clamp and fix the outer side of the cylindrical roller. The end of the cylindrical roller is limited by the limiting opening 8 on the limiting seat 2, and the cylindrical roller can be limited and fixed on the limiting seat 2 and the movable seat 3, reducing the easy dislocation of the core shaft during installation, thereby reducing the difficulty of installation. By using the first linear drive member 10, the movable seat 3 can be moved on the base 1, so as to facilitate the limit fixation of cylindrical rollers of different lengths. By using the telescopic member 17, the height of the supporting sliding seat 5 can be adjusted, and the height of the core shaft on the supporting sliding seat 5 can be adjusted to the height of the cylindrical roller, further reducing the easy dislocation of the core shaft during installation. By setting the second linear drive member 11, the extrusion seat 6 is driven to extrude the core shaft into the inner cylinder of the paper pressing roller, reducing the work intensity of the operator, thereby improving the work efficiency.

[0028] like Figure 3As shown, the relative movement component 12 of this embodiment includes a groove 1201 opened on the movable seat 3, a bidirectional threaded rod 1202 rotatably engaged in the groove 1201, two threaded blocks 1203 slidably engaged in the groove 1201 and threadedly engaged on the bidirectional threaded rod 1202, and a driving member 1204 installed on the bidirectional threaded rod 1202 and passing through the end of the movable seat 3, the two threaded blocks 1203 are respectively fixedly connected to the bottom of the two arc-shaped clamping plates 4; the driving member 1204 is a turning handle or a motor; rubber pads 13 are installed on the opposite sides of the two arc-shaped clamping plates 4, and the rubber pads 13 can protect the pattern on the outer side of the cylindrical roller.

[0029] When the cylindrical roller is limited and fixed on the limit seat 2 and the movable seat 3, the movable seat 3 is first driven to move on the base 1 according to the first linear drive member 10. When the movable seat 3 moves to a suitable length position of the cylindrical roller, the end of the cylindrical roller is placed in the limit opening 8, and the outer side of the cylindrical roller is placed on the movable seat 3. At this time, the drive member 1204 is started, and the drive member 1204 drives the bidirectional threaded rod 1202 to rotate. The rotation of the bidirectional threaded rod 1202 drives the two threaded blocks 1203 to move relative to each other in the groove 1201. The relative movement of the two threaded blocks 1203 drives the two arc-shaped clamping plates 4 to move relative to each other to clamp and fix the outer side of the cylindrical roller. The end of the cylindrical roller is limited by the limit opening 8 on the limit seat 2, so that the cylindrical roller can be limited and fixed on the limit seat 2 and the movable seat 3, reducing the situation where the core shaft is easily misaligned during installation.
