[0002] Hardware processing involves placing metal sheets on machining equipment for shaping. Sheets for hardware processing are cut from coiled steel strips. Coiled steel strips are rolled up and then, when processing hardware, are gradually unrolled. One or more cutting machines are then used to cut the coiled steel strips along their length to form multiple strips. These strips are then cut to length and can be used to make hardware. During the cutting process, the cutting position of the cutting machine is manually controlled and adjusted, allowing the coiled steel strip to be cut into multiple strips of equal or varying widths for use in hardware processing.

[0060] In some embodiments, see Figures 1 to 2The winding assembly 1 includes two sets of support frames 11, a winder 12, and a protective cover 13. The two sets of support frames 11 are spaced apart and have the freedom to be raised and lowered in the vertical direction. The winder 12 is rotatably connected to the two sets of support frames 11 at both ends. The winder 12 is suitable for driving the coiled steel strip 6 to rotate circumferentially. The coiled steel strip 6 can rotate on the winder 12. The winder 12 is electrically connected to the electronic control mechanism 4 and its operation is controlled by the electronic control mechanism 4.

After rotating around the connection between the protective cover 13 and the support frames 11, it forms a plane in the vertical plane. The protective cover 13 forms a semi-enclosure on the side of the coiled steel strip 6 away from the pulling assembly 2. The support height of the support frames 11 can be adjusted and limited, so that the height of the coiled steel strip 6 can be adjusted to ensure that the coiled steel strip 6 is off the ground and is convenient for unrolling and cutting operations. The winder 12 utilizes existing technology and includes a motor and a drive shaft. The two ends of the drive shaft are rotatably connected to the two sets of support frames 11, while the motor is connected to one end of the drive shaft and can drive its rotation.

The protective cover 13 is made of plastic, and its position or angle after rotation or swinging can be limited, so that the protective cover 13 can be fixed in a certain position to protect the coiled steel strip 6.

[0061] In order to fine-tune the position of the coiled steel strip 6 and achieve tensioning of the steel strip 6, in some embodiments, refer to Figures 1 to 2 The two sets of support frames 11 are provided with elongated through-holes 14 near their upper ends. The length of the elongated through-holes 14 is horizontal. Bearings 15 are connected to both ends of the winder 12. The bearings 15 are inserted into the elongated through-holes 14. The position of the bearings 15 in the elongated through-holes 14 can be adjusted and locked to adjust the distance between the coiled steel strip 6 and the pulling assembly 2, thereby making the steel strip 6 unfolded on the coiled steel strip 6 in a tensioned state. The elongated through-holes 14 pass through both sides of the support frames 11 in the width direction. The ends of the drive shafts are connected to bearings 15. The bearings 15 can slide in the elongated through-holes 14, thereby adjusting the position of the coiled steel strip 6 and achieving fine-tuning.

[0062] Specifically, a locking member 16 is provided on the side of the support frame 11 , which can lock the position of the bearing member 15 , thereby fixing the position of the coiled steel strip 6 .

[0063] In some embodiments, see Figure 1 and Figure 3 The pulling assembly 2 is a plurality of groups and is arranged at intervals, each including a sliding seat 21, a sliding plate 22, a telescopic column 23, an upper driving roller 24 and a lower driving roller 25; the upper end of the sliding seat 21 has a slide rail 26, and the length direction of the slide rail 26 is along the width direction of the steel belt 6; the lower end of the sliding plate 22 is slidably connected to the slide rail 26, and the sliding plate 22 has the freedom to slide along the length direction of the slide rail 26, and the side of the sliding seat 21 is connected to a pusher 27 (a telescopic rod in the prior art, which can be telescopically adjusted after being controlled), and the pushing top end of the pusher 27 is connected to the sliding plate 22 and is used to push the sliding plate 22 to slide; the telescopic column 23 is arranged vertically, and the lower end is connected to the upper end of the sliding plate 22, and has Freedom of adjustment along the vertical telescopic extension; the upper drive roller 24 is arranged horizontally and one end is rotatably connected to the side of the telescopic column 23, the upper drive roller 24 is located at the upper end of the steel belt 6 and is used to roll and abut the steel belt 6 to drive the steel belt 6 to expand and move; the lower drive roller 25 is arranged horizontally and one end is rotatably connected to the side of the telescopic column 23, the lower drive roller 25 is located at the lower end of the steel belt 6 and is used to roll and abut the steel belt 6 to drive the steel belt 6 to expand and move, the upper drive roller 24 and the lower drive roller 25 are combined to form a clamp for the steel belt 6, the pusher 27, the telescopic column 23, the upper drive roller 24 and the lower drive roller 25 are all electrically connected to the electric control mechanism 4 and the operation is controlled by the electric control mechanism 4. The sliding plate 22 can slide on the sliding seat 21 and its sliding position is adjustable. By controlling the extension and retraction of the pusher 27, the position of the sliding plate 22 can be adjusted, thereby adjusting the horizontal position of the support and drive of the steel belt 6. By controlling the extension and retraction of the telescopic column 23, the support and drive height of the steel belt 6 can be controlled. In this embodiment, the electronic control mechanism 4 can be manipulated to support and drive the movement of the steel belt 6 at different heights and horizontal positions. The upper drive roller 24 and the lower drive roller 25 form a clamping force to clamp the steel belt 6, thereby driving the movement of the steel belt 6. The upper drive roller 24 and the lower drive roller 25 rotate in opposite directions. In this embodiment, the upper half of the telescopic column 23 has a square columnar structure.

[0064] In order to adjust the distance between the upper driving roller 24 and the lower driving roller 25, it is suitable for clamping and driving the steel belt 6 of different thicknesses. In some embodiments, please refer to Figure 1 and Figure 3A chute 28 is provided at the upper end of the telescopic column 23, near the steel belt 6. One end of the upper drive roller 24 and / or one end of the lower drive roller 25 are slidably connected to the chute 28 and can move and limit within the chute 28 to adjust the distance between the upper drive roller 24 and the lower drive roller 25. A chute 28 is provided on the side (which can be considered the inner side) of the square column structure. One end of the upper drive roller 24 or the lower drive roller 25 can be slidably connected to the chute 28, or both can be slidably connected within the chute 28. By adjusting the position of the upper drive roller 24 or the lower drive roller 25 within the chute 28, the distance between them can be adjusted, thereby enabling the clamping and driving of steel belts 6 of varying thicknesses.

[0065] Specifically, a fastener is connected to the outside of the telescopic column 23, which can fix the upper drive roller 24 and the lower drive roller 25, thereby achieving the limitation of the upper drive roller 24 and the lower drive roller 25 in the slide groove 28. The fixing method of the fastener can be referred to the existing technology and will not be explained here.

[0066] In some embodiments, see Figure 1 and Figure 3 The upper driving roller 24 and the lower driving roller 25 both include a driver 241, a main roller 242, an extension shaft 243 and an extension roller 244; one end of the driver 241 is rotatably connected to the side of the telescopic column 23, and the other end is the power output end.

Thus, the main roller 242 and the extension roller 244 engage the upper and lower ends of the steel strip 6 in rolling contact, clamping and driving the steel strip 6 to move, thereby gradually unwinding the steel strip 6 to facilitate the cutting operation. The lengths of the main roller 242 and the extension roller 244 can be appropriately selected and adapted based on actual conditions. Both rollers can rotate simultaneously, thereby increasing the contact area with the steel strip 6, thereby stably supporting the steel strip 6 and driving its movement.

The support column 31, the plurality of cutters 34 and the plurality of push rods 35 are all electrically connected to the electric control mechanism 4 and their operation is controlled by the electric control mechanism 4. The height of the support column 31 is adjustable, which in turn adjusts the height of the cutter 34. The air duct 32 secures the support plate 33 and also extracts gases or contaminants generated during the cutting process. The cutters 34 utilize existing technology. Multiple cutters 34 are arranged in parallel, enabling simultaneous cutting of the steel strip 6. The distance between the saw blades of two adjacent cutters 34 represents the width of the cut made of the steel strip 6. By manipulating one or more push rods 35, the cutters 34 connected to the push rods 35 can be controlled to slide, adjusting their position and, consequently, the width of the cut made of the steel strip 6. During operation, the appropriate number of cutters 34 can be selected based on the actual width of the steel strip 6.

[0068] To adjust the cutting position of the cutter 34 in the horizontal plane, in some embodiments, refer to Figure 1 、 Figure 4 and Figure 5The upper end of the support column 31 is connected to the bottom end of the rotating platform 36.

The rotating table 36 is an electric rotating table that can achieve circumferential rotation when controlled, thereby driving the cutting machine 34 to move horizontally. The sliding portion 37 is a plate body with a structure such as a slide rail 26 or a slide groove 28 at the bottom end, which can enable the upper end of the wind tube 32 to slide on its bottom end, thereby achieving a sliding connection between the wind tube 32 and the sliding portion 37. Normally, the length direction of the support plate 33 is parallel to the width direction of the steel belt 6. In this embodiment, the length direction of the sliding portion 37 is set at an acute angle to the length direction of the steel belt 6 to achieve the movement and adjustment of the position of the cutting machine 34. In this embodiment, the sliding of the wind tube 32 on the sliding portion 37 can achieve simultaneous adjustment of the positions of multiple cutting machines 34. Specifically, a limit member is provided on the sliding portion 37, which can limit the position of the wind tube 32.

[0069] To prevent environmental pollution during the cutting process, in some embodiments, refer to Figure 1 、 Figure 4 and Figure 5 A dust collector is provided on the outside of the air duct 32 (this is the existing technology, not shown in the figure), and an air duct 38 is passed through the inside of the air duct 32. An exhaust pipe 39 is connected to the bottom of the support plate 33 and the position avoiding the cutting machine 34. The exhaust pipe 39 is axially along the length direction of the support plate 33. A plurality of dust suction ports 310 are provided on the exhaust pipe 39 along its axial direction. One end of the air duct 38 is connected to the dust collector and the other end is connected to the dust collector. The dust collector is used to suck the gas generated by the cutting machine 34 during the cutting process. The gas enters from the plurality of dust suction ports 310. The dust collector is electrically connected to the electronic control mechanism 4 and its operation is controlled by the electronic control mechanism 4. The vacuum cleaner is state-of-the-art, capable of vacuuming, and its parameters, such as the air volume, are adjustable. The location of the dust inlet 310 does not affect the sliding adjustment of the cutter 34. The exhaust pipe 39 is located near the side of the support plate 33, while the multiple cutters 34 are located in the middle of the bottom end of the support plate 33, without interfering with each other. By creating a negative pressure within the air duct 38 and the exhaust pipe 39, gases and impurities generated during the cutting process are drawn into the dust inlet 310 and then into the interior of the vacuum cleaner, effectively preventing environmental pollution. A mounting hole for the air duct 38 is provided on the side of the air duct 32. The air duct 32 is hollow and arranged in a herringbone shape, with the bottom connected to the upper end of the support plate 33.

[0070] In some embodiments, see Figure 1 、 Figure 4 and Figure 5 The cutting machine 34 includes a slide 341, two sets of telescopic rods 342 and a cutting machine body 343. The upper end of the slide 341 is slidably connected to the bottom end of the support plate 33, and its sliding position can be adjusted and limited; the upper ends of the two sets of telescopic rods 342 are connected to the lower end of the slide 341, both are vertical and spaced apart, and the telescopic rods 342 have the freedom to extend and retract vertically; the cutting machine body 343 is connected to the lower ends of the two sets of telescopic rods 342 and is used to cut the steel strip 6. The cutting height of the steel strip 6 by the cutting machine body 343 is adjusted by means of the telescopic rods 342. The telescopic rods 342 and the cutting machine body 343 are both electrically connected to the electric control mechanism 4 and their operation is controlled by the electric control mechanism 4. The cutter body 343 is a conventional product, equipped with a saw blade capable of cutting the steel strip 6. A slide-like structure is provided at the bottom of the support plate 33, on which a slide plate 341 can slide. The sliding direction is along the length of the support plate 33 and the width of the steel strip 6, thereby enabling the position of the cutter body 343 to be adjusted, thereby adjusting the cutting width of the steel strip 6. By controlling the simultaneous extension and retraction of the two sets of telescopic rods 342, the cutting depth or height of the cutter body 343 can be controlled, thereby enabling the cutting of steel strips 6 of varying thicknesses in a single cut. Furthermore, the diameter of the saw blade can be appropriately selected based on the depth and height of the steel strip 6, so that the matching saw blade can be installed on the cutter body 343 to carry out the cutting operation.

[0071] See also Figure 1 、 Figure 6-Figure 8 The present invention also includes a rolling support mechanism 5, which is arranged at the lower end of the steel belt 6 and is used to roll and support the movement of the steel belt 6. The rolling support mechanism 5 can be arranged below or obliquely below the moving stripping mechanism 3. The rolling support mechanism 5 includes an arc-shaped plate 51, a sliding strip plate 52, a plurality of rollers 53 and a plurality of support legs 54. The upper end of the support leg 54 is detachably connected to the arc-shaped plate 51. The convex side of the arc-shaped plate 51 faces upward. The convex side of the arc-shaped plate 51 is provided with a curved rail 55 along its arc direction. The sliding strip plate 52 slides Connected to the curved track 55 and capable of sliding along the curved direction of the track 55, multiple rollers 53 are evenly spaced and connected to the upper end of the sliding strip 52. The rollers 53 are used to roll and support the lower end of the steel strip 6. It is important to note that the positions of the multiple cutters 34 should be staggered or offset from the positions of the multiple rollers 53. This ensures that the cutters 34 do not contact the rollers 53 during the cutting process, ensuring that there is no contact between the rollers 53 and the cutting effect of the steel strip 6. By sliding the sliding strip 52 on the curved track 55, the support height of the rollers 53 on the steel strip 6 can be adjusted. In this embodiment, the support legs 54 can also be removed, allowing the curved plate 51 to be placed on the ground for use.

[0072] Specifically, the length direction of the sliding strip 52 is along the width direction of the steel strip 6, and a slide is set on the upper end of the sliding strip 52 along its length direction, and the two ends of the multiple rollers 53 are connected to the brackets 56, and the lower ends of the brackets 56 are slidably connected in the slide. In this way, the rollers 53 can slide along the width direction of the steel strip 6 to ensure that they are staggered with the position of the cutting machine 34 and do not affect each other. The cutting machine 34 can cut the steel strip 6 at the position between two adjacent rollers 53, such as Figure 1 In this embodiment, the roller 53 can realize arc-shaped sliding adjustment of height and translational sliding movement position, and the distance between two adjacent rollers 53 can also be adjusted.

[0073] After removing the multiple support legs 54 from the arc-shaped plate 51, the lower end of the arc-shaped plate 51 is slidably connected to the large roller 57. The large roller 57 has the freedom of circumferential rotation, and the arc-shaped plate 51 has the freedom of circumferential sliding along the large roller 57. A limiter is provided on the large roller 57, and the limiter can limit the position of the arc-shaped plate 51. Of course, the arc-shaped plate 51 can also be removed from the large roller 57. By rotating the large roller 57, the position of the arc-shaped plate 51 can also be adjusted, thereby adjusting the support height or position of the steel belt 6. In addition, support legs 58 are connected to both ends of the large roller 57. The support legs 58 are rotatably connected to the large roller 57. The support legs 58 are a telescopic component that can be telescopically adjusted, thereby adjusting the height of the large roller 57. After the arc-shaped plate 51 is removed from the large roller 57, the large roller 57 can be used as a conveying roller for conveying the steel belt 6, such as Figure 8 As shown in .

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
