DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0024] In the description of the utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0025] Please refer to Figure 1 A kind of cold-rolled aluminium strip surface cleaning device, consistent with prior art device, including bottom plate 2, bottom plate 2 right side upper side front and rear ends are provided with one limiting plate 3, in actual, cold-rolled aluminium strip is located between two limiting plates 3. At the same time, as shown in the figure, the distance between the right side of the two limiting plates 3 is greater than the distance between the left side of the two limiting plates 3, which is combined with the movement direction of cold-rolled aluminium strip from right to left, can gradually converge cold-rolled aluminium strip, make it from twisted state to vertical, facilitate subsequent processing.

[0026] Correspondingly, since cold-rolled aluminium strip moves from right to left, therefore, the upper and lower axial cleaning roller 1 is rotationally connected above the left side of the bottom plate 2 in front of and behind the device, which can use the cleaning roller 1 to clean the surface of the cold-rolled aluminium strip after convergence.

[0027] It should be noted that, in actual, the two cleaning rollers 1 can be transmission connected (not shown in the figure) and maintain opposite motion trends, which can fully realize the cleaning of the surface of the cold-rolled aluminium strip. Similarly, the side ends of the two cleaning rollers 1 can also be provided with corresponding bristles (not shown in the figure) to improve the cleaning efficiency. This cleaning method using the cleaning roller 1 on the surface of the cold-rolled aluminium strip is not prior art, and the present application does not change it. This is not the main emphasis of the present application, so it will not be described here.

[0028] Specifically, the driving gear 4 is coaxially fixedly connected to the lower end of one of the cleaning rollers 1, and the driving gear 4 serves as the power source for the two cleaning rollers 1.

[0029] Unlike prior art devices, the device is provided with a support mechanism 5 below the two limiting plates 3 to support the cold-rolled aluminium strip, ensuring that the cold-rolled aluminium strip can move smoothly from right to left.

[0030] Specifically, as Figure 2 shown, the support mechanism 5 includes a plate conveyor 502 rotationally connected to the bottom plate 2, the plate conveyor 502 is composed of two chains 5023 symmetrically arranged front and back, and a plurality of scale plates 5022 fixedly connected to the corresponding links of the two chains 5023 between the two chains 5023.

[0031] Meanwhile, a through groove 5021 is formed through each scale plate 5022 from top to bottom, and two through grooves 5021 are formed on a single scale plate 5022 and arranged side by side.

[0032] Specifically, in order to achieve the support and fixation of the plate conveyor 502, the device is provided with a front and rear shaft from the left and right sides of the plate conveyor 502, and each from the shaft 504 is rotatably connected to the bottom plate 2 through a bearing II. At this time, a driven gear 505 is connected to each from the shaft 504 through a key, and the driven gear 505 is in meshing transmission connection with the chain 5023, so that the driven gear 505 cooperates with the from the shaft 504 to support and fix the plate conveyor 502. At the same time, the meshing effect between the driven gear 505 and the chain 5023 also makes the rotation process of the from the shaft 504 closely related to the movement process of the plate conveyor 502.

[0033] Therefore, the device is provided with a plurality of groups of follow-up members around the plate conveyor 502, each group of follow-up members includes two from the assembly 501 arranged symmetrically in front and back, and the two from the assembly 501 are movably connected with the corresponding scale plate 5022. At this time, by arranging the two from the assembly 501 symmetrically in front and back, the from the assembly 501 can be corresponded to the position of the limiting plate 3, and the cold-rolled aluminum strip is located between the two from the assembly 501. Therefore, by abutting the from the assembly 501 with the cold-rolled aluminum strip, the friction force can be used to drive the plate conveyor 502 to move from right to left, thereby achieving the purpose of driving the from the shaft 504 to rotate.

[0034] Therefore, as shown in Figure 4 、 Figure 5 The device is provided with a front and rear transmission shaft 7 between the from the shaft 504 and the cleaning roller 1, the transmission shaft 7 is in transmission connection with the from the shaft 504 through the transmission mechanism 6, and the drive gear 4 is in transmission connection with the transmission mechanism 6 through the transmission gear set 8, at this time, the effect that the cleaning roller 1 can clean the surface of the cold-rolled aluminum strip without driving motor can be achieved.

[0035] Further, in order to improve the relative movement speed between the cleaning roller 1 and the surface of the cold-rolled aluminum strip, and improve the cleaning frequency of the cleaning roller 1 between the cold-rolled aluminum strips, the device restricts the transmission gear set 8 to be a speed increasing gear set, and the rotating speed of the cleaning roller 1 is not less than three times the rotating speed of the from the shaft 504.

[0036] Further, in order to further improve the relative motion speed between the cleaning roller 1 and the surface of the cold-rolled aluminum strip, the device restricts the rotating direction of the cleaning roller 1 opposite to the moving direction of the cold-rolled aluminum strip, that is, the cleaning roller 1 coaxially fixedly connected with the driving gear 4 rotates clockwise, and the rotating direction of the cleaning roller 1 is completely opposite to the conveying direction of the plate conveyor 502.

[0037] It should be noted that, as shown in Figure 2 、 Figure 3 In actual use, the cold-rolled aluminum strip changes to a vertical state due to the influence of the limiting plate 3, so as to avoid the direct contact between the driven assembly 501 and the cold-rolled aluminum strip, and to prevent the driven assembly 501 from being damaged due to the internal stress of the cold-rolled aluminum strip. The device restricts that each driven assembly includes a mounting block 5013, a through hole I is formed in the mounting block 5013 in the front-rear axial direction, a positioning rod 5014 is coaxially inserted into the through hole I, and the two positioning rods 5014 in each driven assembly are fixedly connected with an abutting plate 5011 at the close end.

[0038] Meanwhile, a compression spring 5012 is coaxially sleeved outside each positioning rod 5014, and the two axial ends of the compression spring 5012 are respectively abutted against the corresponding mounting block 5013 and the corresponding abutting plate 5011. At this time, under the action of the compression spring 5012, the two positioning rods 5014 in each driven assembly, that is, the two abutting plates 5011, have a tendency to move towards each other. This can ensure that the abutting plate 5011 is always in abutment with the cold-rolled aluminum strip and does not have direct hard contact with the cold-rolled aluminum strip.

[0039] Further, the device is fixedly connected with a damping pad at the close end of the two abutting plates 5011, and an anti-skid groove is formed in the damping pad. This can further increase the frictional resistance between the driven assembly 501 and the cold-rolled aluminum strip.

[0040] Further, in order to sufficiently ensure that there is sufficient frictional resistance between the abutting plate 5011 and the cold-rolled aluminum strip, and to avoid the abutting plate 5011 and the cold-rolled aluminum strip from being too large due to the bending amplitude of the cold-rolled aluminum strip on the right side of the limiting plate 3, the device is fixedly connected with a slide rail 503 on the front and rear sides of the plate conveyor 502. The distance between the left side of the slide rail 503 and the plate conveyor 502 is greater than the distance between the right side of the slide rail 503 and the plate conveyor 502.

[0041] At this time, by forming a through hole II in each mounting block in the front-rear axial direction, and coaxially fixedly connecting a driven rod 5015 inside the through hole II, and by slidingly connecting each mounting block 5013 with the slide plate 5022 through the slide groove, the driven rod 5015 can be inserted into the slide rail 503 and slidingly connected with the slide rail 503 by restricting the far end of the two driven rods 5015, so as to actively adjust the position of the mounting block 5013, that is, the position of the compression spring 5012.

[0042] Further, in order to reduce the abrasion and improve the service life of the device, a bearing I 5016 is coaxially fixedly connected to the distal end of the driven rod 5015 in the follower member, and the bearing I 5016 is embedded in the sliding rail 503, so as to avoid direct sliding friction, reduce abrasion by converting sliding friction into rolling friction.

[0043] Need to be explained, because the axial direction of the driven rod 5015 does not change, in order to avoid the stroke conflict between the sliding rail 503 and the bearing I 5016, the inner cavity width of the sliding rail 503 must be greater than the width of the bearing I 5016, which can ensure that the inner cavity of the sliding rail 503 can still completely accommodate the bearing I 5016 at the turning section.

[0044] The utility model discloses in actual use process:

[0045] Firstly, the operator embeds the cold-rolled aluminum strip between the two limiting plates 3, at this time, the cold-rolled aluminum strip between the two limiting plates 3 is in the vertical state;

[0046] Then, the operator starts the external power source, and the cold-rolled aluminum strip gradually moves to the left, at this time, the two abutting plates 5011 in the same group abut against the cold-rolled aluminum strip (the existence of the damping pad makes the cold-rolled aluminum strip elastically deform when being extruded, so that the cold-rolled aluminum strip is embedded between the damping pad);

[0047] Afterwards, with the continuous movement of the cold-rolled aluminum strip to the left, the plate conveyor 502 starts to rotate counterclockwise, and the front cleaning roller 1 starts to rotate clockwise;

[0048] Finally, the cold-rolled aluminum strip is embedded between the two cleaning rollers 1, and the cleaning roller 1 starts to clean the surface of the cold-rolled aluminum strip.

[0049] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
