Description

Technical Field

[0001] This utility model mainly relates to the field of composite steel strip, specifically to a composite steel strip slitting machine. Background Technology

[0002] In existing technologies for slitting composite steel strips, a prominent problem often exists: the quality of the cut surface deteriorates due to strip slack. Composite steel strips are typically composed of two or more layers of metal materials with different properties, bonded together through processes such as rolling, welding, or plating. Therefore, high tension control is required during conveying and slitting. During operation, traditional slitting machines are prone to localized or momentary slack in the slitting area due to unstable unwinding tension, deviations in conveyor roller synchronization, or speed fluctuations.

[0003] This slack can cause slight displacement or vibration of the steel strip under the slitting tool, resulting in the cutting path deviating from the preset position. This leads to defects such as burrs, wavy cuts, or delamination on the edges of the slit strip. This not only affects the appearance and dimensional accuracy of the product but may also reduce the bonding strength between composite layers. Especially in subsequent precision machining or assembly applications, substandard cut surfaces often become weak points in the structure.

[0004] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Example

[0029] See attached document Figure 1-5 A composite steel strip slitting machine includes a side support structure 1, wherein the number of the side support structures 1 is set to two, the bottom of the two side support structures 1 is slidably connected to a composite steel strip stretching structure 2, and the top of the two side support structures 1 is slidably connected to a composite steel strip pressing and slitting structure 3.

[0030] The composite steel strip tension structure 2 includes a first lifting plate 201 and a lifting frame 203. The lifting frame 203 has mounting holes 204 at both ends. Mounting strips 205 are installed inside the mounting holes 204. The mounting holes 204 and mounting strips 205 are connected by pins. A rotating strip 206 is rotatably connected to the outer wall of the mounting strip 205. A planar spiral spring is installed between the mounting strip 205 and the rotating strip 206. The first lifting plate 201 is slidably connected between a guide groove 102 and a connecting groove 103. A first rack 202 is provided at the top of the first lifting plate 201. The first rack 202 is connected to a transmission... Gear 104 meshes, and a rotating shaft 207 is rotatably connected to the middle of the lifting frame 203. A rotating wheel 208 is provided on the outer wall of the rotating shaft 207. A pressure groove 209 is opened on the outer wall of the rotating wheel 208. The composite steel belt passes through the bottom of one end of the rotating bar 206 and is in contact with the top of the rotating wheel 208. Then, the composite steel belt rotates around the rotating wheel 208 and bends in an arc at a certain angle before passing through the rotating shaft 207 and contacting the bottom of the rotating bar 206 on the other side. When the composite steel belt is relaxed, the planar spiral spring drives the rotating bar 206 to rotate, causing the rotating bar 206 to stretch the composite steel belt and tighten it.

[0031] Furthermore, the side support structure 1 includes a support base 101. The support base 101 has guide grooves 102 in the middle and on both sides. The support base 101 also has connecting grooves 103 in the middle and on both sides inside. The guide grooves 102 and connecting grooves 103 are aligned. The two sides in the middle of the support base 101 are rotatably connected to transmission gears 104. The number of support bases 101 is set to two. A bracket 105 is set between the two support bases 101. A grinding strip 106 is set at the bottom of the bracket 105. The grinding strip 106 is arc-shaped. When it is necessary to cut the composite steel strip, the composite steel strip is placed into the interior of the composite steel strip stretching structure 2 inside the side support structure 1. Then, the composite steel strip pressing and cutting structure 3 moves downward, driving the composite steel strip stretching structure 2 to move upward. The composite steel strip stretching structure 2 and the composite steel strip pressing and cutting structure 3 cooperate to lift and cut the composite steel strip.

[0032] Furthermore, the composite steel strip pressing and slitting structure 3 includes an electric push rod 301, which is disposed at the top of the inner wall of the support base 101. A second lifting plate 302 is provided at the output end of the electric push rod 301. The second lifting plate 302 is slidably connected between the guide groove 102 and the connecting groove 103. A second rack 303 is provided at the bottom of the second lifting plate 302, and the second rack 303 meshes with a transmission gear 104. Two second lifting plates 302 are provided, and a slitting wheel 304 is rotatably connected between the two second lifting plates 302. When it is necessary to press and slit the composite steel strip... During slitting, the electric push rod 301 is activated, which pushes the second lifting plate 302 downward. The second lifting plate 302 drives the first rack 202 upward through the transmission gear 104. The first rack 202 drives the first lifting plate 201 upward, which in turn drives the inner lifting frame 203 upward. The lifting frame 203 then drives the composite steel strip upward to contact the outer wall of the slitting wheel 304. During the forward movement of the composite steel strip, a motor is installed at one end of the slitting wheel 304. The motor is activated, and it drives the slitting wheel 304 to rotate, thus slitting the composite steel strip.

[0033] When the electric push rod 301 moves upward, it drives the inner slitting wheel 304 to move upward. The outer wall of the slitting wheel 304 contacts the inner wall of the grinding strip 106. As the slitting wheel 304 is rotated by the motor, the grinding strip 106 grinds the slitting wheel 304.

[0034] Preparation and tying:

[0035] The head of the coiled composite steel strip is introduced from below the rotating bar 206 on one side of the machine.

[0036] The steel strip is attached to the groove 209 on the top of the rotating wheel 208, and passes around the rotating wheel 208 to form an arc-shaped support surface.

[0037] The steel strip is then passed under the rotating bar 206 on the other side and guided to the downstream winding or the next process.

[0038] Automatic tensioning:

[0039] If the steel belt becomes loose in some areas due to speed fluctuations or other reasons during equipment operation, the planar spiral spring will automatically release the torque and drive the rotating bar 206 to rotate outward by a certain angle.

[0040] The downward pressing action of the rotating bar 206 generates a downward thrust on the slack section of the steel belt, thereby counteracting the slack and keeping the steel belt taut on the rotating wheel 208 at all times. This is a passive, adaptive tension compensation mechanism.

[0041] Synchronous clamping and cutting:

[0042] When slitting is required, the electric push rod 301 located on top of the support 101 is activated.

[0043] The electric push rod 301 pushes the second lifting plate 302 to move downward along the guide groove 102 and the connecting groove 103.

[0044] The second rack 303, fixed on the second lifting plate 302, descends and engages with the drive gear 104 to rotate.

[0045] The rotation of the transmission gear 104 causes the first rack 202, which meshes with it, to move in the opposite direction, i.e., upward.

[0046] The first rack 202 drives the first lifting plate 201 and the entire lifting frame 203 to move upward synchronously.

[0047] Thus, the top slitting wheel 304 and the bottom rotating wheel 208 move synchronously in opposite directions, stably clamping and slightly lifting the composite steel strip located between them, forming a stable slitting area.

[0048] Start the motor that drives the slitting wheel 304, and the rotating slitting wheel 304 will slit the taut steel strip.

[0049] Online tool sharpening:

[0050] When the slitting operation is completed or the blade needs maintenance, the electric push rod 301 retracts, driving the slitting wheel 304 to rise.

[0051] When it rises to a certain height, the outer edge of the slitting wheel 304 will come into contact with the arc-shaped grinding strip 106 fixed on the bracket 105.

[0052] If the slitting wheel 304 is started to rotate slowly at this time, the grinding bar 106 can perform online grinding on the cutting edge of the slitting wheel 304 to remove burrs, restore sharpness, and extend tool life.

[0053] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
