Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to an aluminum strip trimming device. Background Art

[0002] The raw materials of aluminum strip are pure aluminum or aluminum alloy cast-rolled aluminum coil, hot-rolled aluminum coil, which is rolled into thin aluminum coils of different thicknesses and widths by a cold rolling mill, and then longitudinally cut into aluminum strips of different widths by a slitting machine according to the purpose. The specific uses of aluminum strip are: transformer aluminum strip (transformer aluminum foil), aluminum strip for high-frequency welding hollow aluminum strip, aluminum strip for fin radiator, aluminum strip for cable, aluminum strip for stamping, aluminum strip for aluminum edge strip, etc.

[0003] Before the aluminum strip is used, it needs to go through straightening, trimming, pressing, cleaning and other processes. During the trimming operation, the aluminum strip is usually cut by a trimming wheel using an aluminum strip trimming machine. In the prior art, during the trimming operation, the surface of the trimming wheel is prone to adsorb aluminum chips generated during slitting, and the accumulated aluminum chips will also affect the slitting process. In addition, due to the high production speed, the cut burrs are prone to fly out and scratch the surface of the aluminum strip, affecting the quality of the finished product. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the defects of aluminum chips accumulation and waste edges flying out in the prior art, thereby providing an aluminum strip trimming device.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] An aluminum strip trimming device comprises a frame and trimming pieces, wherein the trimming pieces are symmetrically arranged on both sides of the frame, and a slitting table is arranged in the frame corresponding to the trimming pieces, and further comprises:

[0007] A conveying member, the conveying member is arranged in the frame and conveys the aluminum strip into the trimming member, the conveying member comprises a conveying roller and a guide structure, the guide structure is arranged at the front end of the trimming member, a plurality of conveying rollers are arranged and are located in the frame, both ends of the conveying rollers are positioned and rotatably mounted on the frame, the guide structure comprises a looping pit and a buffer, the looping pit is arranged on the side of the buffer away from the trimming member, and both ends of the buffer are also hingedly arranged on the frame;

[0008] A flattening member, the flattening member is arranged beside the trimming member, the flattening member includes a surface flattening member and a waste edge limiter, the surface flattening member includes a first flattening roller and two second flattening rollers, both ends of the first flattening roller are positioned and rotatably mounted on the frame, the second flattening rollers are arranged at both ends of the first flattening roller, the waste edge limiter is arranged on two symmetrical sides of the frame, and the waste edge limiter includes a limiter box and a limiter roller positioned and rotatably mounted in the limiter box;

[0009] The cleaning piece comprises a collecting structure and a scrapping structure. The collecting structure is arranged in the frame and below the trimming piece, and the scrapping structure is arranged beside the frame and below the scrapping limit.

[0010] By adopting the above technical scheme, the aluminum strip is input by the conveying piece and enters the trimming piece for trimming operation. Before trimming, the conveying aluminum strip is limited to ensure stable transportation. The debris generated by trimming is collected and processed by the collecting structure. The waste edge is led out by the waste edge limit and enters the shredding structure for shredding, avoiding subsequent impact on the trimming piece and reducing the scratches on the surface of the aluminum strip caused by the tumbling of the waste edge, effectively ensuring the normal movement of the trimming piece, and effectively ensuring the safety and cleanliness of the construction environment.

[0011] Furthermore, the buffer member includes a buffer frame, a buffer roller and an adjustment block. The two ends of the buffer frame are hinged to the frame. A plurality of buffer rollers are positioned and rotatably mounted on the buffer frame. The adjustment block is fixed at the two ends of the buffer frame. The adjustment block is extended on the side of the buffer frame away from the feeding direction.

[0012] By adopting the above technical scheme, the buffer is offset by the residual amount of the aluminum strip in the loop pit and the force applied to the buffer when passing through the buffer roller, so that the buffer frame rotates and produces an inclination angle. However, due to the presence of the adjustment block, the buffer frame is lifted in the opposite direction, thereby reducing the collision of the aluminum strip with the side wall of the loop pit when it is conveyed out of the loop pit, ensuring the surface quality of the aluminum strip and reducing scratches.

[0013] Furthermore, the guide structure also includes a guide roller, both ends of which are positioned and rotatably mounted on the frame, the guide roller is arranged above the frame and located on one side of the slitting table, the guide roller includes a roller body, a roller cylinder and a limit cover, the roller cylinder is sleeved on the roller body, the limit cover is threadedly connected to the roller body, and both ends of the roller cylinder are clamped with the limit cover.

[0014] By adopting the above technical solution, the position of the aluminum strip is limited by the guiding structure before entering the trimming piece to avoid deviation. The roller and the roller body are detachably connected and the width of the aluminum strip to be trimmed can be adjusted to meet the needs of different types of plates.

[0015] Furthermore, the second flattening roller includes a pressing roller, a limiting frame and a limiting rod. The two ends of the pressing roller are positioned and installed on the limiting frame. A limiting groove is arranged on the pressing roller. The trimming piece corresponds to the limiting groove. The limiting rod is arranged on the top of the limiting frame and is perpendicular to the slitting table. The limiting rod is a retractable structure.

[0016] By adopting the above technical solution, the first flattening roller radially flattens the surface of the aluminum strip, and the second flattening roller flattens the part that needs to be cut, thereby ensuring the accuracy of the cutting edge and avoiding the deviation of the cutting edge.

[0017] Furthermore, the waste edge limiter is arranged on the side of the trimming piece away from the second flattening roller, the limiting box is an arc surface on the side close to the trimming piece, a plurality of limiting rollers are arranged in an array in the limiting box, and a guide protrusion is also arranged on the side of the slitting table close to the limiting box.

[0018] By adopting the above technical solution, the cut waste edges are introduced into the limiting box by the limiting roller to prevent the waste edges from rolling and scratching the surface of the aluminum strip, and the guide protrusions facilitate separation of the finished aluminum strip and the waste edges.

[0019] Furthermore, the collecting structure includes a collecting hole opened on the cutting table and a collecting tube connected to the collecting hole. The collecting hole is concave, and the bottom of the collecting hole is connected to the collecting tube. A collecting box is also provided at the bottom of the collecting tube, and the collecting box is arranged on the side of the frame.

[0020] By adopting the above technical solution, the collection hole and the collection tube cooperate to quickly collect the aluminum chips generated after trimming to ensure the cleanliness of the processing operation area. An exhaust or dust collection device can be set in the collection box to connect to the collection tube to improve the collection efficiency.

[0021] Furthermore, the edge breaking structure includes a guide roller, an extrusion plate and a shredding roller. The extrusion plate is arc-shaped and is arranged above the guide roller. An extrusion spring is also connected between the extrusion plate and the frame. Two shredding rollers are arranged relatively to each other and are located below the guide roller. A waste box is also arranged below the shredding roller, and the waste box is arranged on the side of the frame.

[0022] By adopting the above technical solution, the scrap edge crushing structure will crush the scrap edges introduced into the limiting box and drop them into the waste box for collection. Since the scrap edge shredding process will cause the scrap edges to tumble, an extrusion plate is added to limit them to avoid affecting the front end trimming process.

[0023] Furthermore, the cleaning piece also includes a cleaning structure, which is symmetrically arranged on both sides of the frame and located at the end of the trimming piece away from the guide structure. The cleaning structure includes a cleaning roller and a grinding roller. The axis of the grinding roller is vertical, and the axis of the cleaning roller is perpendicular to the axis of the grinding roller.

[0024] By adopting the above technical solution, the cleaning structure facilitates rough grinding of the aluminum strip after the trimming is completed and removes aluminum chips on the surface through the cleaning roller to ensure surface cleanliness.

[0025] In summary, the technical solution of the utility model has the following advantages:

[0026] 1. The utility model provides an aluminum strip trimming device, in which the aluminum strip is input by a conveying member and enters a trimming member for trimming operation. Before trimming, the aluminum strip is conveyed with a limit to ensure stable conveying. The debris generated by trimming is collected and processed by a collecting structure, and the waste edge is led out by the waste edge limit and enters a shredding structure for shredding, thereby avoiding subsequent influence on the trimming member and reducing the scratches on the surface of the aluminum strip caused by the tumbling of the waste edge, effectively ensuring the normal movement of the trimming member, and effectively ensuring a safe and tidy construction environment.

[0027] 2. The aluminum strip trimming device provided by the utility model has a crushing structure that crushes the waste edges introduced into the limiting box and drops them into the waste box for collection. Since the waste edges will tumble during the shredding process, an extrusion plate is added to limit them to avoid affecting the front-end trimming process. BRIEF DESCRIPTION OF THE DRAWINGS
