Description

Technical Field

[0001] This utility model relates to a multi-layer sheet rolling guide structure. Background Technology

[0002] Rolling is an important metal processing technology that involves passing a metal billet through the gap between a pair of rotating rolls. The compression of the billet by the rolls reduces its cross-section or deforms it, increasing its length. In sheet metal rolling, a conveyor belt continuously and smoothly transports the sheet material into the gap between the two rolls. However, due to misalignment during installation, the sheet material is prone to shifting or deviating during transport, leading to errors in the rolling process. This is especially true for multi-layer sheet metal composite rolling; positional deviations during installation or transport can significantly impact the quality of the composite sheet rolling, preventing effective composite rolling of multiple layers. Utility Model Content

[0003] This utility model mainly solves the technical problems existing in the prior art, thereby providing a multi-layer plate rolling guide structure that can ensure the guidance and stability of multi-layer plate conveying, effectively prevent the plate conveying or installation position from deviating, and improve the rolling quality of multi-layer plates.

[0004] This utility model relates to a multi-layer sheet rolling guide structure, comprising a vertical frame and horizontal plates connected to both sides of the vertical frame. A first abutment shaft and a second abutment shaft are movably connected to the horizontal plates on one side of the vertical frame for limiting and guiding the sheet material. Adjustment mechanisms connected to the horizontal plates are located at both ends of the first and second abutment shafts. A pressing mechanism for pressing the sheet material is located on the side of each adjustment mechanism and connected to the horizontal plates. Each adjustment mechanism includes a column connected to the horizontal plates and a movable block located on the side of the column and movably connected to the horizontal plates. An end shaft is connected above the movable block, and a first spring is connected between the end shaft and the column. The pressing mechanism includes a connecting rod movably connected to the horizontal plates. A stop plate is connected to the upper end of the connecting rod, and a pressing wheel is movably connected to the lower end of the connecting rod through the horizontal plates. A second spring is located between the stop plate and the horizontal plates.

[0005] Preferably, a mandrel is connected to the center of both the first and second abutment shafts. The second abutment shaft is located near the side of the pressing wheel and between the extrusion mechanism and the first abutment shaft, so that the conveyed sheet material can pass through the first abutment shaft, the second abutment shaft and the pressing wheel in sequence, so that the sheet material can be guided by the first or second abutment shaft and the multi-layer sheet material can be pressed and bonded by the pressing wheel.

[0006] Preferably, spacers are connected to the center of the first abutment shaft and both sides of the second abutment shaft. Two or more first discs are connected to both sides of the first abutment shaft, and two or more second discs are connected to the center of the second abutment shaft.

A first protective sleeve is connected between two adjacent first discs, and a second protective sleeve is connected between two adjacent second discs. The outer diameter of the spacers is smaller than the outer diameter of the first or second protective sleeve. The first and second protective sleeves isolate the first and second discs, facilitating the support and guidance of the sheet metal by the first or second discs. The first and second protective sleeves limit the edge of the sheet metal. The spacers separate the guide height of the first and second abutment shafts. The different outer diameters of the spacers and the first and second protective sleeves facilitate guiding and limiting the sheet metal. The staggered arrangement of the first and second discs avoids contact and collision between the first and second abutment shafts during the limiting and conveying of the sheet metal.

[0007] Preferably, the movable block is movably connected to the end of the spindle, and a waist groove is provided in the center of the horizontal plate. The movable block is slidably connected to the center of the waist groove, so that the spindle can pass through the first abutment shaft and the second abutment shaft to facilitate movable connection with the movable block. The movable block is slidably connected in the waist groove to guide and limit the sliding of the first abutment shaft and the second abutment shaft. The movable block and the spindle can be movably connected by a bearing.

[0008] Preferably, the outer surfaces of the end shaft and the column are both fitted with bushings, and the upper ends of the end shaft and the column are connected with limiting plates for limiting the bushings. The two ends of the first spring are respectively connected to the bushings, so that the bushings are fitted outside the end shaft and the column, and are limited by the limiting plates to prevent the bushings from detaching from the end shaft and the column.

[0009] Preferably, the lower end of the connecting rod passes through the horizontal plate and is connected to a wheel frame. A rotating shaft passing through the pressing wheel is connected to the center of the wheel frame. The pressing wheel is movably connected to the center of the wheel frame, so that the lifting and lowering of the connecting rod can drive the pressing wheel to lift and lower. The pressing wheel can rotate in the center of the wheel frame through the rotating shaft. The pressing wheel shaft is perpendicular to the shafts of the first and second contact shafts. Thus, the rotation direction of the pressing wheel is the direction in which the plate is supported and transported by the first or second contact shaft.

[0010] Preferably, the abutment plate is connected above the connecting rod, and the abutment plate has a rhomboid structure. Guide rods connected to the horizontal plate are movably connected to both sides of the abutment plate. An outer frame connected to the horizontal plate is externally connected to the guide rods, so that the lifting and lowering of the abutment plate can drive the lifting and lowering of the connecting rods. During the lifting and lowering process, the abutment plate is limited and guided by the guide rods. The outer frame is set to connect and fix the guide rods to increase stability and firmness, and to limit the rising height of the abutment plate. Through holes are provided on both sides of the abutment plate, and the guide rods are slidably connected to the through holes.

[0011] Preferably, the upright frame is movably connected to a guide roller on one side of the first and second contact wheels. There are two or more guide rollers, and the outer surface of the guide rollers is connected to a rubber pad so that the board can be placed between two adjacent guide rollers and supported by the guide rollers. At the same time, the rubber pads isolate and protect the moving board to prevent scratches.

[0012] Preferably, one side of the support frame is connected to an insert cylinder, one end of the guide roller passes through the insert cylinder and is detachably connected to a nut, the guide roller and the insert cylinder are fitted with a clearance, so that one end of the guide roller can be embedded in the insert cylinder and can rotate inside the insert cylinder, and the nut is provided to facilitate the connection and fixation of the end of the guide roller to prevent the guide roller from detaching from the insert cylinder, the nut and the guide roller are threaded together, and the outer diameter of the nut is larger than the outer diameter of the insert cylinder.

[0013] Preferably, a fixing plate is connected to the side of the upright frame away from the first and second abutting wheels. A sleeve is connected to the surface of the fixing plate, and a support rod is connected to the center of the sleeve. Bolts for fixing the support rod are threaded to the outer surface of the sleeve, so that the support rod can be sleeved in the sleeve outside the fixing plate, and the support rod is pressed and fixed by the bolts on the outer surface of the sleeve.

[0014] The beneficial effects of this utility model are as follows: Because the central part of the horizontal plate is movably connected with a first abutment shaft and a second abutment shaft, the first and second discs connected to the outer surfaces of the first and second abutment shafts respectively support, guide, and limit the multiple layers of boards at different heights. Simultaneously, the first spring in the adjustment mechanism pulls the first and second abutment shafts via a movable block, thereby facilitating the corresponding centering and limiting of the edges of the multiple layers of boards. This ensures synchronous and stable conveying of the multiple layers of boards, avoiding deviations during installation or output. In cases where rolling deviations occur, the sheet material, guided and limited by the adjustment mechanism, the first contact shaft, and the second contact shaft, is conveyed to the center of the pressing rollers on both sides of the upright. The second spring in the extrusion mechanism pulls the connecting rod through the abutment plate, causing the pressing rollers on both sides to come into contact with the surface of the sheet material. This allows the multi-layer sheet material to be pressed and limited, ensuring the stability of the multi-layer sheet material during continuous conveying, reducing the possibility of subsequent deviations, ensuring the guidance and stability of the multi-layer sheet material during conveying, and improving the quality of the sheet material after being pressed and limited by the pressing rollers before entering the rolling mill for rolling.

The first sleeve 22 and the second sleeve 32 limit the edge of the sheet metal. The spacer 23 separates the first abutting shaft 2 and the second abutting shaft 3 at different guide heights. The different outer diameters of the spacer 23 and the first sleeve 22 and the second sleeve 32 facilitate the guiding and limiting of the sheet metal. The staggered arrangement of the first wheel 21 and the second wheel 31 avoids contact and collision between the first abutting shaft 2 and the second abutting shaft 3 when limiting and conveying the sheet metal.

The center of the wheel frame 6 is connected to the rotating shaft 62 that passes through the pressing wheel 61. The pressing wheel 61 is movably connected to the center of the wheel frame 6, so that the lifting and lowering of the connecting rod 54 can drive the pressing wheel 61 to lift and lower. The pressing wheel 61 can rotate in the center of the wheel frame 6 through the rotating shaft 62. The shaft of the pressing wheel 61 is perpendicular to the shafts of the first abutment shaft 2 and the second abutment shaft 3. The rotation direction of the pressing wheel 61 is the direction in which the plate is supported and transported by the first abutment shaft 2 or the second abutment shaft 3.

[0027] The abutment plate 52 is connected above the connecting rod 54, and the abutment plate 52 has a rhomboid structure. Guide rods 55 connected to the horizontal plate 11 are movably connected to both sides of the abutment plate 52.

During the lifting and lowering process, the abutment plate 52 is limited and guided by the guide rods 55. The outer frame 51 is set to connect and fix the guide rods 55 to increase stability and firmness, and to limit the rising height of the abutment plate 52. Through holes (not marked) are provided on both sides of the abutment plate 52, and the guide rods 55 are slidably connected to the through holes.

[0028] The upright frame 1 is movably connected to a guide roller 7 on one side of the first contact wheel 2 and the second contact wheel 3. There are two or more guide rollers 7, and the outer surface of the guide roller 7 is connected to a rubber pad 71 so that the board can be placed between two adjacent guide rollers 7 and the board can be supported by the guide rollers 7. At the same time, the rubber pad 71 isolates and protects the moving board to prevent the board from being scratched.

[0029] One side of the support frame 1 is connected to an insert 72. One end of the guide roller 7 passes through the insert 72 and is detachably connected to a nut 73.

[0030] A fixing plate 13 is connected to the side of the upright frame 1 away from the first abutting wheel 2 and the second abutting wheel 3. A sleeve 131 is connected to the surface of the fixing plate 13. A support rod 133 is connected to the center of the sleeve 131. A bolt 132 for fixing the support rod 133 is threaded to the outer surface of the sleeve 131, so that the support rod 133 can be sleeved in the sleeve 131 outside the fixing plate 13. The bolt 132 on the outer surface of the sleeve 131 is used to press the support rod 133 to support and fix the upright frame 1.

[0031] Two multi-layer sheet rolling guide structures are provided, each connected and fixed to both sides of the sheet conveyor belt by support rods 133. The sheets to be laminated from top to bottom are arranged at different heights and sequentially placed onto guide rollers 7 at corresponding heights for support. Simultaneously, the sheets are distributed according to their height onto the first disc 21 or second disc 31 on the outer surface of the first contact shaft 2 or the second contact shaft 3.

The first spring 43 and the second spring 53 can be tension springs.

[0032] The beneficial effects of this utility model are as follows: Because the central part of the horizontal plate is movably connected with a first abutment shaft and a second abutment shaft, the first and second discs connected to the outer surfaces of the first and second abutment shafts respectively support, guide, and limit the multiple layers of boards at different heights. Simultaneously, the first spring in the adjustment mechanism pulls the first and second abutment shafts via a movable block, thereby facilitating the corresponding centering and limiting of the edges of the multiple layers of boards. This ensures synchronous and stable conveying of the multiple layers of boards, avoiding deviations during installation or output. In cases where rolling deviations occur, the sheet material, guided and limited by the adjustment mechanism, the first contact shaft, and the second contact shaft, is conveyed to the center of the pressing rollers on both sides of the upright. The second spring in the extrusion mechanism pulls the connecting rod through the abutment plate, causing the pressing rollers on both sides to come into contact with the surface of the sheet material. This allows the multi-layer sheet material to be pressed and limited, ensuring the stability of the multi-layer sheet material during continuous conveying, reducing the possibility of subsequent deviations, ensuring the guidance and stability of the multi-layer sheet material during conveying, and improving the quality of the sheet material after being pressed and limited by the pressing rollers before entering the rolling mill for rolling.
