[Prior Art] During the electrolytic treatment of metal strips, as a result of the field intensity ratio, so-called dendritic crystals are deposited on the edges of the ribbon. This can result in problems; processing can cause problems; for example, if dendritic crystals fall off, they will leave marks on the surface of the strip. This is why after the electrolytic treatment: Immediately remove these dendritic crystals formed during the electrolytic treatment, especially at the edges of the bands. To this end, mechanical dendritic crystal removal devices such as blades, brushes, or the like have been proposed; in order to avoid injury to the bands, while ensuring that dendritic crystals can be completely removed, the inevitable answer is: The tool needs to provide very precise strip guidance. Especially when there is a change in the degree, the mechanical stripping device and / or the strap itself may be miscellaneous, or may not be able to cause damage as the speed and accuracy are adjusted. This is why related processes and devices have been proposed, such as the European patent 978 575 A1, which sprays high pressure liquid directly onto the strip to remove dendritic crystals. This requires a considerable amount of instrument liquid. In addition, the dendritic crystals that have been separated by the book α, have been removed by the load and returned to the band. Set Qi 86004 200419014 [Summary of the invention] The task of μ is to remove the ③ / large crystal as described above. The mechanical device; it allows the most likely removal at the edge of the strip = clogged crystal, while providing protection against injury The best protection of the strip and / or stripping device, even when the width of the strip is convex and concave. To achieve this task, the present invention foresees at least-a mechanical stripping device that is fixed to the brace towards the edge of the strip with a spring prestress, wherein the brace is rigidly held on the interval roller ⑽ running along the edge of the material. Because the support and the k-wheel are connected together, the support will follow the track of the interval roller, which ensures that the mechanical stripping device is automatically guided at the optimal distance from the edge of the strip 'without manual adjustment. . According to the advantageous structure of this month, the mechanical stripping device (its support and spacer rollers are movable) is installed in the guide block, and the guide mechanism is generally at a right angle to the longitudinal axis of the strip . These features allow the entire stripping device to be easily adjusted at the same time, while having a longer lateral path relative to the strip axis compared to separate installations. In order to prevent tilting during lateral movement, another feature of the present invention predicts that the guide block will run on two parallel rails. 〃 、 L # 品 要再 了。 The whole removal device is equipped, for example, the stripping device can obtain approximately the same amount of pushing force at the edge of the strip that moves a large degree, or at the same time, the center point of the strip is at a horizontal level relative to the longitudinal center of the stripping device. Compensate if there is a deviation. For this function, a preferred embodiment of the device according to the invention is characterized by a guide block, which is adapted to be placed along the guide mechanism by means of a preferred air pressure drive. 86004 200419014 million. Therefore, it would be advantageous if the pneumatic drive was controlled directly by the actuated valve. ,

The outer case protects the mentioned components from mechanical damage and at the same time resists the spray of aggressive liquids. It is possible in principle to avoid the need to seal the casing and at the same time ensure protection against aggressive and gaseous media; but because of its sluggish function, it will hinder the adjustment of the stripping device; the casing according to the invention has another specific example of advantages It can provide protective gas and keep its internal air chamber pressure higher than atmospheric pressure. [Embodiment] A blade 丨 or a similar stripping or crushing device that runs along the edge of the strip not shown in the figure is fixed to the support arm 2; the preferred way of the above screws can be disassembled And replacement. As for the support arm 2, its installation enables the support arm to be rotated on the strip horizontal plane about the axis 3 substantially perpendicular to the strip axis, and is also movable at the support frame 4; wherein the support frame 4 is installed at the The pivoting bearing is substantially parallel to the second shaft 5 of the shaft 3, and the mounting structure will be described in detail later. A spacer roller 6 is installed here, and preferably rotates about the same axis 3 as the support arm 2 ′ and as it moves through the entire device, it can travel along the edge of the strip, so it can be ensured by the axis 3 ( The same from the support arm) to the strip 86004 200419014 The edge of the strip is always kept at the same distance, regardless of whether there is a change in the width of the strip or any other change in the size of the strip. In any case, the axis of the support arm 2 may be arranged at a constant distance from the axis 3 of the spacer roller 6. To achieve this design, the support arm 2 is shaped like a two-armed rod pivoting about an axis 3, fixing the blade 1 to a lever arm, and the other arm is located on the opposite side of the axis 3 and is connected to Spring 7 or similar elastic element. This spring 7 or the like acts on the support arm 2 so that the lever arm of the support blade 丨 is pushed toward the edge of the strip in a manner that the blade 丨 presses against the edge of the strip V with the lever arm's transmitted force and Moving along the edge of the strip has the effect of removing the dendritic crystals located on the edge of the strip. A limit stop 8 for the lever arm of the support arm 2 is connected to the spring 7 to limit the pivotal movement of the blade 丨 towards the strip. The spaced rollers 6 shown in Figure lb should preferably have grooves 6a distributed around the circumference of the rollers (it would be advantageous if the grooves are v-shaped cross-sections) to grip the edges of the strip, which ensures a reliable strip guide. It would be advantageous if the beam 4 located in the area close to the spacer roller 6 is designed to extend around the roller 6 in a frame shape so as to hold the roller while holding the support arm 2 firmly. The support arm 2 is also configured in the same way, with two members distributed above and below the spacer roller 6, and two springs 7 are preferably provided above and below the central horizontal plane of the beam 4 to ensure support The symmetrical effect of the power of arm 2. The sectional view of FIG. 2 shows the supporting structure for the aforementioned components 丨, 2 and 6, in which the tail end portion of the beam (reference number 号码) is fixed to the second shaft 5. Tail end The center of the bolt has a torsion resistant lining (preferably: a ball or ball bearing) at the tail end of the bolt 9 to restrain the tired plug 9 from the pivot lining of the guide block 10. The guide block ⑺ mounted on two 86004 ^ 0419014 guide rails 12 (the guide rails preferably have a circular cross-section), and therefore the entire device with Ik < bolt 9 and components in contact with the strip, is roughly relative Strip running direction can be moved at right angles. In order to make the entire device that comes into contact with the strip can be pressed against the strip, the top of the bolt 9 is provided with an additional elastic element 13 which acts on the ring plate μ or the like, which is protruded from the top of the bolt 9 Or it can be fixed to the bolt by reverse torque. The spring 13 affects the bolt 9 in such a way that the bolt ㈣ spaced the roller 6 in the direction of rotation and follows it (while the support arm 2 on which the additional knife P is mounted) toward the edge of the strip and presses against it. In order to cover more movements in the width of the strip than in the way of only the rotating bolt 9, the guide block 12 is arranged on the guide rail 12 so that it can move at a right angle with respect to the rotation of the strip. Here, the spring is better equipped with two pretension springs 15 above and below the level of the guide rail 12 to ensure that the force I exerted by the guide block 10 acts on the center of the strip and therefore presses in this direction. Arrive at the strip. 3 is a horizontal projection showing an elliptical opening y opening 16 extending on a part of the circumference of the disc 14. When the disc 14 and the bolt 9 accompanying it are rotated, it follows the stop pin 17 provided in the guide block 10. mobile. The combination of the stop pin 17 and the elliptical opening 16 restricts the rotation range of the disc 14. Therefore, the space roller ^ and the component connected thereto come into contact with the strip and do not swing too far toward the center of the strip. Figure 4a shows the horizontal projection viewed from the upper end of the casing of the device according to the invention when it is opened; Figure 4b provides a view viewed from the lower end, that is to say from the position of the strip. In the operating state, the housing is completely closed except for the oval slot 19, which is approximately at a right angle 86004 -10- 200419014 with respect to the running direction of the strip, and the bolt 9 is penetrated by the housing 18 through the slot. The casing is provided with a feeding device for compressed air or protective gas (not shown in the figure). Due to this setting, the money reduction is kept at a pressure higher than atmospheric pressure, so that steam is not included, i prevent Electrolyte or the like is sprayed into the casing, and the function of the device is impaired due to corrosion or the formation of crystals on the inside. In addition, the ㈣ # cylinder 20 (preferably pneumatic) is provided in each guide block 10 in the casing 18, and is moved by applying a force to the guide block through the adjustment sleeve. This is particularly advantageous, in order to provide a longer adjustment path, on the one hand, and on the other, if it moves through the device without acting correctly on the center, it can provide the same pushing force on either side of the strip the amount. The adjusting sleeve 20 is fixed to the housing 18, and its piston rod 21 acts on the guide block 10, preferably at the arm protruding from the side of the horizontal plane of the guide rail 2; if the arm is fixed at It would be advantageous to be close to the spring 15. As can be roughly seen from Figs. 5a to 5c, the entire device according to the present invention has a symmetrical structure, so that dendritic crystals can be removed at any one side of the strip at the same time, and any lateral direction due to the sin component at the edge of the strip The force can be mostly compensated. The housing 18 provided with the guide rail 12 and the adjustment sleeve 20 is installed with the bracket 22 and placed above the strip, so that the cross beam 4 for the spacer roller 6 and the blade 1 can be practically used to remove the bar from the upper end Zoned dendritic crystals. Therefore, the risk that the aggressive liquid from the strip enters the inside of the casing can be largely avoided; even the protective gas or sealed air above the atmospheric pressure inside the casing can further reduce this risk. . [Brief description of the drawings] 86004 -11-200419014 In the following description of the present invention, an example with additional drawings will be used to provide a more detailed description. Figure 1a shows that the mechanical stripping device starts to contact the strip, and the contact rollers protrude horizontally, that is, perpendicular to the horizontal plane of the strip; Figure lb shows that the stripping device is located parallel to the strip axis; Figure 2 shows the stripping device The sectional view of the entire supporting and guiding structure is completed except for the device.
