Description

Technical Field

[0001] This utility model relates to the field of steel wool processing. More specifically, this utility model relates to an automatic steel wool sandpaper forming device. Background Technology

[0002] Steel wool has good softness and better abrasion resistance than fibers such as cotton and linen. It also has abrasion and polishing properties, and can replace sandpaper and abrasive cloth for polishing the surfaces of wood and metal products. Currently, commercially available steel wool products have a structure similar to steel wool balls, consisting of long strips of steel wool rolled up. Common steel wool sandpaper on the market is mainly made by rolling a long, thin strip of steel wool into a thick roll, forming a block-shaped piece of steel wool sandpaper.

[0003] With changing demands, a new structure has emerged in the steel wool sandpaper market. This new structure uses a short strip of steel wool of a certain width, which is rolled into a thin roll along its length and then pressed into shape to obtain a block of steel wool sandpaper. However, this structure suffers from drawbacks because the steel wool strip used is relatively short and difficult to break manually. Furthermore, manual rolling cannot guarantee the stability of the formed steel wool sandpaper.

[0004] To address the aforementioned issues, utility model patent CN 218802740 U provides an automatic sandpaper forming machine, enabling rapid and automatic forming of steel wool abrasive paper. However, in actual production, the width and thickness of the steel wool strips used for different specifications of steel wool abrasive paper vary, and the aforementioned automatic steel wool abrasive paper forming equipment can only process steel wool strips of fixed sizes. Therefore, it is necessary to develop an automatic steel wool abrasive paper forming equipment applicable to various specifications of steel wool abrasive paper. Utility Model Content

[0052] The present invention will be further described in detail below with reference to the embodiments, so that those skilled in the art can implement it based on the description.

[0053] It should be noted that in the description of this utility model, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0054] like Figures 1-5 As shown, an embodiment of this utility model provides an automatic steel wire sandpaper forming device, including a cotton strip conveying mechanism 1, a cotton strip cutting mechanism 2, a horizontal conveying mechanism 3, and a pressing mechanism 4 arranged in sequence, and further including:

[0055] The first guide trough 5 is disposed between the cotton strip conveying mechanism 1 and the cotton strip cutting mechanism 2;

[0056] The second guide trough 6 is disposed between the cotton strip cutting mechanism 2 and the horizontal conveying mechanism 3;

[0057] The third guide trough 7 is disposed between the horizontal conveying mechanism 3 and the pressing mechanism 4;

[0058] A curling and forming mechanism is disposed above the horizontal conveying mechanism 3, and the lower end of the curling and forming mechanism has a rough forming surface;

[0059] A height adjustment mechanism 9 is connected to the curling and forming mechanism;

[0060] A guide mechanism 10 is disposed above the conveying surface of the horizontal conveying mechanism 3. The guide mechanism 10 includes two baffles located on both sides of the conveying surface of the horizontal conveying mechanism 3, and a guide groove is formed between the two baffles.

[0061] In this embodiment, the steel wire cotton strip passes sequentially through the cotton strip conveying mechanism 1, the first guide groove 5, the cotton strip cutting mechanism 2, and the second guide groove 6. The cotton strip conveying mechanism 1 drives the steel wire cotton strip to move at a uniform speed. The first guide groove 5 and the second guide groove 6 limit the movement trajectory of the steel wire cotton strip, sending it into the horizontal conveying mechanism 3. The cotton strip cutting mechanism 2 works periodically to cut the steel wire cotton strip. The cut steel wire cotton strip is conveyed forward by the horizontal conveying mechanism 3. When the steel wire cotton strip comes into contact with the coiling and forming mechanism, its front end contacts the forming surface of the coiling and forming mechanism, slowing down its movement speed. This causes the steel wire cotton strip to gradually coil into a roll, and finally be sent out by the horizontal conveying mechanism 3. When the steel wire strip on the horizontal conveyor 3 comes into contact with the coiling and forming mechanism, its front end contacts the forming surface of the coiling and forming mechanism, and its moving speed is slowed down, causing the steel wire strip to gradually coil into a roll, and finally be sent out by the horizontal conveyor 3, and enter the pressing mechanism 4 through the third guide chute 7, where it is pressed and formed.

[0062] During the steel wool strip curling process, the guide groove formed by two baffles limits the movement trajectory of the steel wool strip, preventing it from deflecting during curling and ensuring that the rolled steel wool product is neatly cylindrical. When processing steel wool strips of different specifications, the height of the curling and forming mechanism can be adjusted using the height adjustment mechanism 9, and the distance between the forming surface and the conveyor gate of the horizontal conveying mechanism 3 can be adjusted to meet the thickness of the steel wool strip. Simultaneously, the distance between the two baffles can be adjusted according to the width of the steel wool strip, ensuring that the width of the guide groove matches the width of the steel wool strip.

[0063] Preferably, in another embodiment of the present invention, the cotton belt conveying mechanism 1 includes:

[0064] A first upper roller and a first lower roller are set at an interval;

[0065] The first drive unit is connected to the first upper roller and the first lower roller respectively.

[0066] In this embodiment, the first drive unit drives the first upper roller and the first lower roller to rotate synchronously in opposite directions, thereby moving the steel wool belt between the first upper roller and the first lower roller. The first drive unit can utilize existing technology and will not be described in detail here.

[0067] Preferably, in another embodiment of the present invention, the cotton tape cutting mechanism 2 includes:

[0068] The cutting table 21 has its two ends connected to the first guide groove 5 and the second guide groove 6, respectively.

[0069] A cutter 22 is vertically disposed above the cutting table 21, and the upper end of the cutting table 21 is provided with a cutting groove corresponding to the cutter 22;

[0070] The telescopic cylinder 23 is mounted above the cutter 22 via a gantry, and the push rod of the telescopic cylinder 23 is set vertically downward and connected to the cutter 22.

[0071] In this embodiment, the telescopic cylinder 23 drives the cutter 22 to move up and down. The cutter 22 moves down into the cutting groove, so that the steel wire cotton strip on the cutting table 21 can be cut by the cutter 22.

[0072] Preferably, in another embodiment of the present invention, the pressing mechanism 4 includes:

[0073] A second upper roller and a second lower roller are arranged at intervals.

[0074] The second drive unit is connected to the second upper roller and the second lower roller respectively.

[0075] In this embodiment, the second drive unit drives the second upper roller and the second lower roller to rotate synchronously in opposite directions. The second upper roller and the second lower roller compress the curled steel wool strip into shape and then send out the compressed steel wool abrasive paper. The second drive unit can use existing technology and will not be described in detail here.

[0076] Preferably, in another embodiment of the present invention, the curling and forming mechanism includes:

[0077] Connecting plate 81, the upper end of which is connected to the height adjustment mechanism 9;

[0078] A molding plate 82 is disposed below the connecting plate 81 and connected to the connecting plate 81 via an angle adjustment component. The lower end of the molding plate 82 forms the molding surface.

[0079] In this embodiment, the connecting plate 81 and the height adjustment mechanism 9 can adjust the angle between the forming plate 82 and the connecting plate 81 through the angle adjustment component, thereby adjusting the angle of the forming surface of the curling forming mechanism to meet the curling needs of steel wire cotton strips of different thicknesses and lengths.

[0080] Preferably, in another embodiment of the present invention, the lower end of the forming plate 82 gradually tilts downward along the conveying direction of the horizontal conveying mechanism 3.

[0081] In this embodiment, the lower end of the forming plate 82 gradually tilts downward along the conveying direction of the horizontal conveying mechanism 3, so that the steel wire cotton strip moves forward a certain distance on the horizontal conveying mechanism 3 before it begins to be rolled into shape, thus avoiding the steel wire cotton strip from getting stuck between the forming plate 82 and the horizontal conveying mechanism 3 after being rolled into shape due to moving too far on the horizontal conveying mechanism 3.

[0082] Preferably, in another embodiment of the present invention, the angle adjustment component includes:

[0083] A hinge 83 is disposed between the connecting plate 81 and the forming plate 82 and is connected to both of them respectively;

[0084] The first screw 84 vertically penetrates the connecting plate 81;

[0085] The first nut 85 is threaded onto the first screw 84 and located above the connecting plate 81;

[0086] The rotating component 86 has one end rotatably connected to the upper end of the forming plate 82, and the other end rotatably connected to the lower end of the first screw 84.

[0087] In this embodiment, the forming plate 82 is hinged to the connecting plate 81 via a hinge 83. A first nut 85 rests on the connecting plate 81, fixing the first screw 84 and thus securing the connecting plate 81. Because the steel wool tape has a low density, the forming plate 82 is made of metal to ensure that the position of the forming plate 82 does not change when the steel wool tape comes into contact with it. The angle of the forming plate 82 can be adjusted by rotating the first nut 85 and adjusting its position on the first screw 84.

[0088] Preferably, in another embodiment of the present invention, the height adjustment mechanism 9 includes:

[0089] Two sets of adjustment units are spaced apart along the conveying direction of the horizontal conveying mechanism 3. Each adjustment unit includes:

[0090] Bracket 91;

[0091] The second screw 92 vertically penetrates the bracket 91, and its lower end is connected to the connecting plate 81;

[0092] The second nut 93 is threaded onto the second screw 92 and located above the bracket 91.

[0093] In this embodiment, the curling and forming mechanism is supported on the bracket 91 by two second nuts 93. By rotating the second nuts 93, the position of the second nuts 93 on the second screw 92 can be adjusted, thereby adjusting the height of the curling and forming mechanism.

[0094] Preferably, in another embodiment of the present invention, the guide mechanism 10 further includes:

[0095] Two sets of support components are respectively connected to the two baffles. The support components include:

[0096] An upper support 102 is connected to the baffle, and the upper support 102 is provided with a strip-shaped through hole 103;

[0097] The lower bracket 104 is slidably connected to the lower end of the upper bracket 102 at its upper end.

[0098] A positioning screw 105 is vertically disposed on the upper end of the lower bracket 104, and the positioning screw 105 passes through the strip-shaped through hole 103;

[0099] The positioning bolt 106 is threaded onto the positioning screw 105.

[0100] In this embodiment, the positioning bolt 106 is loosened, and the position of the baffle is adjusted by sliding the upper bracket 102. At this time, the positioning screw 105 slides within the strip-shaped through hole 103. After tightening the positioning bolt 106, the upper bracket 102 and the lower bracket 104 are fixed, thus fixing the position of the baffle.

[0101] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
