Abstract
Description
Technical Field
[0001] This utility model relates to a pull-out roller brush mechanism. Background Technology
[0002] The main function of the roller brush mechanism used for cleaning the interior of shot blasting equipment is to remove steel shot and oxide debris (rust, etc.) from the steel plates inside the equipment. It should be understood that the wear of the roller brush affects the cleaning effect and recovery performance of the shot blasting equipment under different operating conditions. When designing the cleaning function for a specific shot blasting machine, the roller brush must meet cleaning standards during equipment operation, requiring timely replacement of the roller brush components.
[0003] Most roller brushes are fixedly installed in the cleaning chamber. Due to the rolling of the roller brush, the cleaning range is relatively small. The roller brush mechanism cannot be flexibly adjusted according to the on-site working conditions. When replacing parts, special personnel need to enter the cleaning chamber to carry out the work, which is not only inefficient but also poses safety hazards.
[0004] In view of this, in some implementations, a pull-out opening is provided on one side panel of the cleaning chamber, and the roller brush mechanism is made as a whole into a roller brush assembly. The roller brush assembly can be inserted into the cleaning chamber through the pull-out opening. When changing the roller brush, the roller brush assembly can be pulled out through the pull-out opening, and the replacement of the roller brush can be completed outside the cleaning chamber, and then reset.
[0005] It should be understood that the pull-out roller brush assembly must be operated from one side. If the roller brush assembly lacks internal support, it will inevitably be in a suspended state, which cannot guarantee the smoothness of the pull-out. Therefore, guide rails are often configured to facilitate the reliable operation of the roller brush assembly in the predetermined direction. However, it should be understood that although the shot blasting chamber (the cleaning chamber is located at the bottom of the shot blasting chamber) is equipped with dust extraction equipment, the dust discharged by the dust extraction equipment is mostly dust with a relatively large specific surface area. As mentioned above, the shot material, as well as the removed materials such as rust, will settle to the bottom of the shot blasting chamber. During this process, certain surfaces, such as horizontal surfaces, will inevitably support some shot material or rust, which can easily cause the guide rails and the sliders that cooperate with the guide rails to become stuck or jammed.
[0006] Furthermore, the slider is generally replaced by a roller assembly, which is less prone to jamming. However, the guide rail adapted to the roller usually has roller grooves or other structures to prevent the roller from slipping, which can easily accumulate shot or rust, affecting the smooth operation of the roller. Utility Model Content
[0007] The purpose of this invention is to provide a pull-out roller brush mechanism with relatively good reliability.
[0008] In an embodiment of this utility model, a pull-out roller brush mechanism is provided, comprising:
[0009] support;
[0010] The slide rail has two parallel slide rail components that are parallel to each other and parallel to the pulling direction; the slide rail components are fixedly suspended to the lower side of the bracket by slide rail buckles located on the outer side of the slide rail components; the cross section of the slide rail components is inverted V-shaped.
[0011] The roller brush assembly includes a roller brush seat and a roller brush mounted on the roller brush seat. Roller assemblies are provided on both sides of the roller brush seat. The roller grooves of the rollers in the roller assemblies are V-shaped grooves, and the rollers straddle corresponding slide rail components.
[0012] A drive device to drive the roller brush to rotate;
[0013] The upper part of the roller brush seat is located between the two slide rail components to avoid motion interference with the slide rail buckle.
[0014] Optionally, the brush holder of the aforementioned pull-out roller brush mechanism may be constructed as a protective cover;
[0015] Accordingly, the upper side panel of the roller brush holder is formed as a sloping panel, so that the upper part of the roller brush holder is an isosceles trapezoid.
[0016] The roller seat of the roller is mounted on the slope panel.
[0017] Optionally, the roller seat includes a mounting base parallel to the slide rail, and a connecting plate for fixing the mounting base to the slope panel;
[0018] Both the mounting base plate and the connecting plate are vertical plates.
[0019] Optionally, the slide rail buckle is a U-shaped buckle;
[0020] Correspondingly, the openings of the U-shaped buckles on both sides of the bracket face each other, so that the U-shaped buckles avoid the rollers and are fixedly connected to the lower side of the slide rail.
[0021] Optionally, the protective cover further includes a side cover plate located below the slope panel, forming the lower part of the roller brush seat, the side cover plate being a vertical plate; and
[0022] End plates used to seal the slope panels and side guards located on both sides at both ends;
[0023] The roller brush is mounted on the end plate via a bearing housing.
[0024] Optionally, the bracket is equipped with a lifting structure to accommodate the lifting mechanism, thereby allowing the bracket to move up and down within the cleaning chamber.
[0025] Optionally, the lifting structure includes lifting guide rollers disposed at both ends of the bracket.
[0026] Optionally, the lifting structure includes a lifting seat mounted on a bracket that cooperates with the lifting mechanism.
[0027] Optionally, the lifting seat is provided at both ends of the bracket via lifting rings or lead screw nuts.
[0028] Optionally, the support is a rectangular frame structure;
[0029] The rectangular frame must have at least a crossbeam.
[0030] The pull-out roller brush mechanism according to this utility model uses a slide rail with an inverted V-shaped cross-section, i.e., a V-shaped slide rail. The slide rail surface is inverted, making its slope outwards, thus preventing the accumulation of shot or debris and ensuring smooth pull-out of the roller brush assembly. The roller grooves of the rollers fitted with the roller brush assembly are V-shaped grooves, allowing for a straddle-type fit with the slide rail. The resulting track pair has a relatively large mating surface, ensuring smooth roller operation. Attached Figure Description

[0036] Figure 4 In the case of a pull-out roller brush mechanism, a pull-out opening needs to be opened on one side of the cleaning chamber. A slot for inserting a plate can be opened at the pull-out opening to accommodate the insert plate, which is used to cover the pull-out opening after the pull-out roller brush mechanism is reset.
[0037] In a pull-out roller brush mechanism, the pulling direction of the roller brush assembly is also the axial direction of the roller brush shaft, which is in... Figure 2The bracket shown corresponds to the longitudinal direction of the bracket, and thus corresponds to the names determined by the orientation of the horizontal frame 10, vertical frame 12, etc. shown in the figure.
[0038] Furthermore, the distinction between inside and outside is often definite; for example, the space between two slide rail components is the inside, and the opposite is the outside.
[0039] In an embodiment of this utility model, the pull-out roller brush mechanism first includes a bracket and a roller brush assembly, wherein the bracket is the mounting base for resetting the roller brush assembly into the cleaning chamber.
[0040] exist Figure 2 In the illustrated structure, the support is a frame structure. Figure 2 In the middle, the horizontal frame 10 and the vertical frame 12 are assembled into a rectangular frame by welding, riveting, or bolting. Figure 2 The structure also includes four crossbeams 19, which are evenly arranged longitudinally and can be connected to the longitudinal frame 12 by welding, riveting or bolting.
[0041] In some embodiments, if the diameter of the roller brush is relatively large and the width (lateral dimension) of the adapted bracket is relatively large, a longitudinal beam may also be provided.
[0042] The support frame can be fixed or movable within the cleaning chamber. Figure 1 and 2 The illustrated structure is equipped with structural components suitable for lifting and lowering the support, such as the lifting ring 9, the connecting port 8, and the lifting guide roller 7 shown in the figure.
[0043] exist Figure 1 and Figure 2 In the illustrated structure, a slide rail component is provided on each of the left and right sides of the bracket, and the two slide rail components constitute slide rail 15.
[0044] exist Figure 2 The illustrated structure more clearly shows that the slide rail components are arranged in a suspended manner on the lower side of the frame structure's support, such as... Figure 1 and Figure 2 The slide rail buckle 13 shown in the figure wraps around the outside of the slide rail component to the bottom of the slide rail component to support the slide rail component, and can be fixedly connected to the slide rail component by welding.
[0045] The obvious parallelism between the two slide rail components, and parallel to the pulling direction of the pull-out roller brush mechanism, is easy to understand based on the concept of this utility model, and will not be elaborated further here.
[0046] Regarding the aforementioned pull-out opening, after the roller brush assembly is reset, the insert plate can be inserted into the corresponding slot, thereby limiting the roller brush assembly from the outside of the pull-out opening and preventing the roller brush assembly from coming out.
[0047] Regarding the shape of the slide rail component, instead of rectangular guide rails or dovetail guide rails, a V-shaped guide rail is used, which is installed on the bracket in an inverted manner. The cross-section of the slide rail component is an inverted V-shape, with its two rail surfaces located on the left and right sides of the slide rail component and intersecting at the upper end of the slide rail component.
[0048] Furthermore, the two sets of rollers installed on both sides of the roller brush assembly constitute a structure as follows: Figure 1 The slide rail rollers 14 shown in the figure have two sets of rollers forming two roller groups. The roller groups correspond one-to-one with the slide rail components, and are respectively mounted on the roller brush seats on both sides of the roller assembly.
[0049] The roller groove of the slide rail roller 14 of the roller assembly is a V-shaped groove, which is adapted to the inverted V-shape of the slide rail component and straddles the corresponding slide rail component.
[0050] Because the slide rail component is inverted V-shaped, it will not accumulate shot or impurities on the track surface, thus ensuring that the slide rail roller 14 runs reliably on the slide rail component.
[0051] In addition, a drive unit is provided to drive the roller brush to rotate, which is an inherent configuration of the roller brush assembly and will not be described in detail here.
[0052] It should also be noted that the upper part of the roller brush seat is located between the two slide rail components to avoid motion interference with the slide rail buckle 13.
[0053] Regarding the roller brush, either a bristle brush (1) or a wire brush can be used. Relatively speaking, bristle brush (1) is softer, such as... Figure 4 In the illustrated structure, the pull-out opening can be relatively small, yet it can still satisfy the requirements of pulling out or resetting.
[0054] exist Figure 1 and Figure 3 In the illustrated structure, the brush holder is a cover-type structure, and is generally represented as a protective cover for the brush.
[0055] Since the roller brush can be understood as a rotating body as a whole, the roller brush holder that houses the roller brush can be made of an arc-shaped plate, while... Figure 3 In the illustrated structure, the upper part of the brush holder is constructed with a sloping panel 22, which makes the upper part of the brush holder form an isosceles trapezoidal structure.
[0056] Obviously, the inner surface of the slope panel 22 is tangent to the top circle of the roller brush, and an interference avoidance distance can also be left. Under this condition, Figure 3 The top plate 21 shown for interconnecting the two slope panels 22 can be a horizontal plate.
[0057] In addition, the lower edge of the slope panel is connected to the side cover 17, which is a flat plate and forms a vertical plate, and the side cover 17 is parallel to, for example, the axis of the brush shaft 4.
[0058] Correspondingly, due to its inclined arrangement, the sloped panel 22 provides a certain space above the side guard 17, which is suitable for the installation of the roller seat, such as... Figure 1 The installation of the slide rail roller seat 16 shown is that the slide rail roller seat 16 is fixedly installed on the slope panel 22.
[0059] from Figure 3 As can be seen in the illustrated structure, by mounting the slide rail roller seat 16 on the slope panel 22, the space freed up by the slope panel 22 due to its inclined setting is fully utilized, and the overall structure is relatively compact.
[0060] Furthermore, in Figure 3 In the illustrated structure, the slide rail roller seat 16 is generally U-shaped and includes a mounting base plate parallel to the slide rail member, and two connecting plates for fixed connection between the mounting base plate and the slope panel. Both the mounting base plate and the slope panel are vertical plates, and the connecting plates are perpendicular to each other with the mounting base plate.
[0061] The lower edge of the connecting plate is attached to the surface of the slope panel 22, and is preferably fixed to the slope panel 22 by welding.
[0062] Both the mounting base plate and the connecting plate are vertical plates.
[0063] Additionally, the roller brush holder has an end plate 5 for sealing the slope panels and side guards located on both sides at both ends. The end plate 5 has a mounting hole 20, and a bearing seat 2 is provided at the mounting hole 20 for, for example, mounting the brush shaft 4.
[0064] Figure 2 As can be seen, the slide rail buckle 13 used for mounting the slide rail 15 is a U-shaped buckle, so that the space between the two legs of the U-shaped buckle is used to allow the slide rail 15 and the slide rail roller 14 running on the slide rail 15 to pass each other and avoid motion interference.
[0065] In terms of position, the opening of the U-shaped buckle faces inward, and correspondingly, the openings of the two sets of U-shaped buckles are opposite each other in the left-right direction, that is, the openings face inward as mentioned above.
[0066] The lower side of the slide rail component and the U-shaped buckle can be connected by welding.
[0067] In addition, Figure 2 In the illustrated structure, a column is provided at the end of the horizontal frame 10, and a support bracket 18 is provided at the lower end of the column to support the slide rail component from the end.
[0068] To broaden its application range, the bracket is equipped with a lifting structure to accommodate a lifting mechanism. Accordingly, the lifting mechanism adjusts the bracket by raising or lowering it through the lifting structure, thereby adjusting the position of the roller brush assembly in the vertical direction within the cleaning chamber.
[0069] To ensure the smoothness of lifting, the lifting structure includes lifting guide rollers 7 at both ends of the support, and correspondingly, a lifting guide rail is provided on, for example, the side panel 23 of the cleaning chamber for guiding the lifting guide rollers 7.
[0070] As mentioned above, since the roller brush holder adopts a cover-type structure in the preferred embodiment, the lifting structure includes a lifting seat that is mounted on the bracket and cooperates with the lifting mechanism.
[0071] Furthermore, the lifting seat is a lifting ring 9 or a screw nut disposed at both ends of the support. For example, the lifting ring 9 can be connected and driven by a rope from a winch mechanism, while the screw nut can be driven by a lifting screw.
