Description

Technical Field

[0001] This utility model relates to the technical field, and more specifically to a steel strip casting machine and its slitting device. Background Technology

[0002] A steel strip casting machine is a device used to cast liquid materials into continuous films or sheets. It has a wide range of applications in many industrial fields such as electronics, ceramics, and plastics. The equipment and the slitting device are completely separate. The slitting device is an important part of the production line. Its function is to cut the wide material after casting into products of different widths according to production needs.

[0003] A common slitting device consists of a fixed frame, slitting blades, and slotted wheels. The fixed frame serves as the basic support structure for the entire slitting device. The blades of the slitting blades are detachable and can be used to match materials of different materials. The slotted wheels are connected to the transmission system. By using the slots to fit against the edges of the materials, the materials are driven to move at a uniform speed while preventing material deviation.

[0004] The problem with the blade mounting structure of the aforementioned slitting cutter is that the disassembly and assembly takes too long, resulting in long downtime for equipment due to blade replacement, which affects production progress and increases the labor intensity of operators. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model proposes a steel strip casting machine and its slitting device, which shortens the blade replacement time of the slitting device, improves the blade replacement efficiency, simplifies the blade replacement operation, and ensures the production progress of the steel strip casting machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slitting device is used to slitting the material produced by a steel strip casting machine. The material is a continuous film or sheet. The slitting device includes a grooved roller and a multi-group slitting cutter. The grooved roller can rotate around a central axis, and the outer circumference of the roller contacts the material. It is used for the continued downstream conveying of the material and also for cutting the material together with the multi-group slitting cutter.

[0008] The outer roller surface of the grooved roller is provided with multiple annular grooves that are concave inward along the radial direction of the grooved roller. The multiple grooves are distributed at intervals along the axial direction, and each groove is coaxial with the grooved roller.

[0009] The multi-component slitting cutter is suspended above the grooved roller by a cutter support frame. The position of each cutter on the cutter support frame is adjustable along the axial direction of the grooved roller by a cutter adjustment assembly. Any groove can be matched with a slitting cutter. The blade of the slitting cutter is positioned with its cutting edge facing the groove, extending tangentially to the grooved roller, and contacting the material passing through it. It works with the groove to cut the material. The blade is detachably mounted on the slitting cutter by a cutter changing assembly.

[0010] The slitting device is further configured as follows:

[0011] It also includes a slitting frame, conveying rollers, support rollers, and a conveying motor. The entire slitting device is fixedly spanned across the material by the slitting frame. The conveying rollers and support rollers are arranged vertically opposite each other and adjacent to each other upstream of the grooved rollers. They are rotatably supported on the slitting frame around the central axis. The gap between the outer roller surfaces allows the material to pass through. The conveying motor drives the conveying rollers to rotate in the direction of material conveying. The material passing through contacts the outer roller surfaces of the conveying rollers and support rollers respectively, and is conveyed downstream to the grooved rollers by the conveying rollers and support rollers. The grooved rollers are rotatably supported on the slitting frame, and the cutter support frame is fixedly spanned across the slitting frame.

[0012] The slitting tool includes a tool fixing block, a blade, a tool changing assembly, and a tool adjusting assembly. The tool adjusting assembly is located on top of the tool fixing block and includes an L-shaped adjusting plate and adjusting bolts. The L-shaped adjusting plate is connected to the top of the tool fixing block via a vertical plate segment, and a horizontal plate segment extends parallel above the top of the tool fixing block, forming a clamping cavity between them. The tool is slidably clamped onto the tool support frame along the axial direction of the grooved roller through the clamping cavity, and is secured to the tool support frame by adjusting bolts threaded through the horizontal plate segment of the L-shaped adjusting plate.

[0013] The tool changing assembly includes a fixed shim, a movable abutment, a movable slider, and a tool changing bolt. A blade mounting groove is formed on the tool fixing block. The fixed shim is fixedly attached to one side wall of the blade mounting groove. A tool changing screw hole is pre-drilled in the blade mounting groove for threaded engagement with the tool changing bolt. A slotted hole adapted to the tool changing bolt is pre-drilled on the movable slider. The movable abutment is fixedly installed towards one end of the fixed shim. The movable abutment and the fixed shim are opposite each other, with the back of the blade sandwiched between them. The movable slider can be fastened to the tool fixing block by a tool changing bolt that passes through the slotted hole and is threaded into the tool changing screw hole. The distance between the movable abutment and the fixed shim is adjustable by the engagement between the tool changing bolt and the slotted hole.

[0014] The length of the waist-shaped hole is parallel to the axial direction of the groove roller.

[0016] The finished material is fed to the conveying device through the feed port, then conveyed to the slitting device, and after being slitted by the slitting device, it is conveyed to the winding machine, which winds up the slitted material. The waste generated after slitting is recovered by the waste recycling device set between the slitting device and the winding machine.

Both the hinge shaft and the connecting shaft are parallel to the axial direction of the grooved roller. The drive motor drives the collecting wheel to rotate. The waste to be recycled sequentially passes around the swing slide wheel and the lifting slide wheel, and is wound onto the collecting wheel.

[0019] The transport device includes a transport frame and a transport motor mounted on the transport frame, an active transport roller and a driven transport roller that are rotatable and face each other vertically, with a gap between the two rollers for materials to pass through.

The grooved roller 11 can rotate around the central axis, and the outer circumference is in contact with the material. It is used for the continued conveying of the material downstream and is also used to cut the material together with the multi-group slitting cutter 12.

[0038] The outer roller surface of the groove roller 11 is provided with multiple ring-shaped grooves 111 that are concave in the radial direction of the groove roller 11. The multiple rings of grooves 111 are distributed at intervals along the axial direction, and each ring of grooves 111 is coaxially distributed with the groove roller 11.

[0039] The multi-component slitting cutter 12 is suspended above the grooved roller 11 by the cutter support frame 13. The position of the cutter on the cutter support frame 13 is adjustable along the axial direction of the grooved roller 11 by the cutter adjustment assembly.

The distance between the movable abutment 127 and the fixed shim 126 is adjustable through the engagement between the tool changing bolt 1210 and the slotted hole 129. The tool changer bolt 1210 is made of high-strength alloy steel, which has high strength, good toughness and hardenability, and is used to withstand the large force during the adjustment process; the movable slider 128 is made of wear-resistant cast iron, which has good wear resistance and a certain strength; the fixing shim 126 is made of rubber, which has good elasticity and cushioning performance, and effectively absorbs the impact force generated during slicing; the movable stop 127 is made of the same tool steel as the tool fixing block 121, which has sufficient strength and wear resistance, and has good contact performance with the blade 122 to prevent damage to the blade 122.

[0046] The length of the waist-shaped hole 129 is parallel to the axial direction of the grooved roller 11.
