When carrying out bonding strength test to roll chromium plating layer, need to carry out grid scribing to roll main roll surface by scribing part 4, scribing is finished by two scribing cones 472, and in this implementation, two scribing cones 472 The distance between the tip of the cone is 25mm, which represents the width of the scribing grid in the axial direction of the roll. In addition, the scribing cone 472 will form a loss at the tip of the cone during the long-term scribing process. The detachable double-headed scribing The part 47 has not only facilitated the sharpening treatment of the awl point of the marking cone 472, but also facilitates direct replacement.

When scribing, first complete the circumferential scribing of the roll, and then carry out the axial scribing, so that several circular arc rectangular grids are formed by separating the circumferential lines and the axial lines. Specifically, when performing circumferential scribing, the scribing member 4 is first moved and switched to directly above the roll through the traverse switching assembly 33, so that the two scribing cones 472 are located on the vertical plane of the central axis of the roll, The entire test preparation mechanism 3 is driven by the traversing mechanism 2 to move intermittently and equidistantly in the axial direction of the roll to obtain a plurality of equidistant test points. The line member 4 descends as a whole along with the traverse switching assembly 33, so that the cone tips of the two scoring cones 472 are inserted on the chrome-plated layer of the roll, and as it continues to descend, the compression spring 46 shrinks, and under the action of elastic force, the scoring cones The piercing depth of the cone tip of 472 increases until the cone tip of the marking cone 472 penetrates the chrome plating layer completely, and the descending stroke of the pressing cylinder 32 is recorded. Complete the scribing of two circumferential lines, then repeat the circumferential scribing operation, complete the circumferential scribing at the test points selected in the axial equidistant distribution of the rolls, and then carry out the axial scribing, and press down the cylinder 32 to keep The same descending stroke as that of circumferential marking keeps the marking cone 472 in the state of penetrating the chrome plating layer, and then drives the marking part 4 to move in the axial direction of the roll through the traversing mechanism 2, thereby completing an axial movement of the roll. Marking, in the process of axial marking, the servo motor self-locks to keep the roll in a fixed state, then, the servo motor drives the roll to rotate at a certain set angle, and repeats the axial marking operation again, and then rotates intermittently at equal angles each time Finally, an axial scribing is completed. After the circumferential scribing and axial scribing are completed, several grids distributed continuously in the circumferential direction are formed at each selected test point.

In addition, during the whole scribing process, the scribing component 4 is kept in the blowing state, and the pressurized air entering the air pipe 45 will enter the air chamber 441 along the air pipe 45, and finally blow out from each air channel 4711 , the blown pressurized air can not only clean the chrome coating powder produced during the scribing process simultaneously, but also clean the area between and near the two circumferential scribing lines synchronously to complete the synchronous automatic cleaning , which is beneficial to ensure the bonding precision and bonding strength between the strong tape and the mesh surface in the subsequent process, and avoid the dust and powder on the surface of the roll from adversely affecting the testing process.

As shown in Fig. 1, Fig. 4 and Fig. 8, the pressure roller mechanism 5 includes an elastic telescopic roller frame 51, and the elastic telescopic roller frame 51 includes a vertical guide block 511 fixed on the bottom end of the slide plate 333 by bolts, and the bottom end of the vertical guide block 511 There are two guide rods 512 vertically sliding at the end, and the bottom ends of the two guide rods 512 are welded with a roller frame 513 horizontally. 511 and the roller frame 513 , the roller frame 513 is horizontally rotatably mounted with a pressure roller 52 , and the axial direction of the pressure roller 52 is parallel to the sliding direction of the electric slider 23 . Roll frame 513 side is provided with guide part 53, and guide part 53 comprises guide frame 531, and guide frame 531 comprises two connecting side plates 5311 that are welded on both sides of roll frame 513 one by one and horizontally welded on two connecting side plates 5311. The horizontal plate 5312 between is located above the horizontal plate 5312 and three guide rollers 532 are vertically rotated on the two connecting side plates 5311. The axial direction of the rollers 52 is distributed horizontally. Two sets of guide rollers 532 are equidistantly arranged with respect to the equidistant central points of the two scribe cones 472 , and the upper end surface of the horizontal plate 5312 is slightly lower than the horizontal tangent surface of the lower end of the pressure roller 52 . It should be noted that the pressing roller 52 can be driven to rotate by a motor, and an existing motorized roller can also be selected as the pressing roller 52 .

Each arc-shaped rectangular grid chrome-plated layer formed by scribing part 4 is used as a unit for bonding strength test. During the test, each selected ring-shaped grid area on the roll surface Both need to be closely covered with the strong tape used for the peel test. The strong tape can be selected and purchased in the market. The selected strong tape needs to have a corresponding definite peel strength parameter of the adhesive force. The peel strength parameter needs to be greater than the chrome plating layer of the roll to be tested The set qualified strength parameters of the strong tape, and the tape products whose peel strength parameters are closer to the set qualified strength parameters of the chrome-plated layer of the roll are preferred.

When carrying out strong adhesive tape bonding and covering, specifically, the pressure roller mechanism 5 is first moved to the test point at the most lateral end through the traverse mechanism 2, and then the pressure roller mechanism 5 is traversed and switched to the roller through the traverse switch assembly 33. directly above, so that the central axis of the pressure roller 52 and the central axis of the roll are on the same vertical plane, and then, the pressure roller mechanism 5 is driven down by the pressing cylinder 32 to descend as a whole with the traverse switching assembly 33, and then descends to the pressure roller 52. Until there is a gap through which the strength tape can pass between the roll and the roller, in order to form a conveying pressure on the strength tape, the actual gap should be slightly smaller than the thickness of the strength tape, and then place one end of the cut-off strength tape above the horizontal plate 5312, and Pass between the two sets of guide rollers 532, and send them into the gap. As shown in Figure 3, the strong adhesive tape is fed in from the right side, and the servo motor will drive the rollers to rotate counterclockwise, while the pressure roller 52 will rotate clockwise. , and then convey the strong tape to the left, and fit and cover it on the circumferential grid area. When the strong tape is fitted and covered, the guide part 53 can provide a favorable guide, so that the strong tape can be centered and covered On the circumferential grid area, when the strong tape has a small inclination at the feeding end, it is obvious that the degree of deviation will increase with the circumferential coverage.

After the strong adhesive tape is pasted, continue to lower the pressure roller 52, so that the telescopic spring 514 generates compression, and the pressure roller 52 produces a pressing force on the strong tape. When the pressure roller 52 is kept pressed and in the non-starting rotation state, the servo motor The roll is driven to rotate repeatedly to and fro, so that the strong adhesive tape is rolled and compressed by the pressure roller 52, so as to improve the bonding tightness of the strong adhesive tape on the roll. Then, move the roller axially through the traversing mechanism 2, and repeat the bonding and winding of the strong adhesive tape and the reciprocating rolling operation at each selected test point.

The multiple test strong tapes after the fit and coverage are completed can be uniformly clamped on an existing clamping plate, and the clamping plate is fixed on the tension end of the existing tension machine, so that the strong tapes remain vertically tight , and then loosen the self-locking mechanism of the servo motor, so that the rollers can be kept in a state of free rotation. Under the release of the free rotation of the rollers, the clamping plate is pulled at a constant speed by the tension machine, so that multiple strong tapes are peeled off on the rollers synchronously, and the peeling is completed. Finally, observe the bonding surface of each strong tape to see if the chrome layer of the mesh unit is peeled off from the roll and adhered to the strong tape. When the bonded chrome layer appears on the strong tape, it indicates the strength of the strong tape The peeling strength is greater than the bonding strength of the chrome-plated layer of the grid unit at the corresponding position, so that the phenomenon of detachment from the roll appears, that is, the bonding strength of the chrome-plated layer at this position is not up to the standard. Through comprehensive comparative analysis of each strong adhesive tape, it can be qualitatively Get the bonding strength distribution of the chrome plating layer on the roll surface.

The invention provides a device for testing the strength of the chrome-plated layer on the roll repair, which can test the bond strength of the chrome-plated layer on the roll surface after the chrome-plated layer is repaired on the roll, and can replace manual automatic selection of test parts on the roll surface, and It can carry out automatic grid distribution division on the chrome plating layer, and simultaneously clean the test site for dust cleaning during the grid division process. In addition, it can perform manual testing on the test sites selected by multiple test strong tapes relative to the roll. Covering and winding one by one, and can perform automatic reciprocating rolling and compacting operation on the attached strong tape, the whole test preparation process basically replaces the completion of automatic operation, and can complete the simultaneous test of multiple test parts, greatly improving the efficiency of the test , and avoid the random operation error problem in the manual repeated operation process, improve the accuracy of the test, and can better truly reflect the distribution of the overall bonding strength of the chrome plating layer of the roll, which has a higher reference value.
