[0002] During the production and application of steel plates and steel strips, the raw materials need to be unrolled and sent out for use because of the coiling of the raw materials. The head of the plate and strip is usually in a bent structure, which directly affects the quality and performance of use. In severe cases, the plate and strip cannot be connected to the production equipment during use. Summary of the invention

[0003] The utility model provides an eccentric clamping conveyor which has a compact structure and can effectively and stably correct and convey a plate belt with a bent material head.

[0004] The technical scheme adopted by the utility model is: an eccentric pinch conveyor, including a base and two side plate frames, the left and right sides of the base respectively support and connect the two side plate frames, and the characteristics are: the lower front parts of the two side plate frames can be rotatably connected to the lower pinch conveyor rollers, the upper front parts of the two side plate frames are provided with upper lifting grooves, and guide plates are provided in the upper lifting grooves for guiding the up and down lifting, the upper pinch conveyor rollers can be rotatably connected between the guide plates of the two side plate frames, the lowest point of the upper pinch conveyor roller and the highest point of the lower pinch conveyor roller are located on the same horizontal line, and the center of the upper pinch conveyor roller is behind the center of the lower pinch conveyor roller On the side, lifting cylinders are arranged on the plate frames on both sides, and the lower part of the lifting cylinders is connected to the guide plate; two support seats are respectively arranged on the left and right sides of the lower rear side of the plate frames on both sides, and the two support seats respectively support inclined blocks, and the lower ends of the inclined blocks are guided in the left and right directions and supported on the support seats for horizontal sliding. The two inclined blocks are threaded with an adjusting screw rod with an external hand wheel, and the threads on the adjusting screw rod that are connected to the two inclined blocks have opposite rotation directions. The two guide seats are respectively supported on the two inclined blocks, and the two guide seats are arranged in the lower lifting groove on the side plate frame for lifting and lowering, and the adjusting roller is rotatably connected between the two guide seats.

[0005] The upper and lower pinch rollers and the regulating roller are steel roller structures, or a rubber layer structure is arranged outside the steel roller.

[0006] A compression spring is arranged between the top wall of the lower lifting groove and the guide seat.

[0007] The guide plate is movably connected with a synchronous shaft, and two sides of the synchronous shaft extend out of two side frames and are connected to external synchronous gears, and the synchronous gears mesh with synchronous racks outside the two side frames.

[0008] The synchronous rack is connected to a calibration screw rod below, and the calibration screw rod is connected to a calibration seat on the outer side of the side plate frame and is locked and positioned by a nut.

[0009] The adjusting screw rod is formed by connecting two ends of the optical axis with screw rod sections with opposite rotation directions at two ends.

[0010] The highest point lifting and lowering calibration range of the adjusting roller is within the upper and lower range of the horizontal line of the highest point of the lower pinch roller.

[0011] The shaft ends of the upper and lower pinch rollers passing through the plate frame on either side are connected to a rotation driving device.

[0012] The beneficial effects of the utility model are:

[0013] 1. The upper and lower pinch rollers are set eccentrically, which can well introduce pinching and conveying for the bent structure of the plate and strip material head, and send it to the position of the adjusting roller. The hand wheel drives the adjusting screw to rotate, driving the two inclined blocks to move relative to each other, thereby lifting the guide seat height, thereby adjusting the highest point position of the adjusting roller, realizing the lifting and anti-bending correction of the bent structure of the material head, and meeting the straight performance requirements for subsequent plate and strip production and transportation.

[0014] 2. The guide plate of the upper pinch roller is connected to the synchronous shaft, and the calibrated synchronous racks at both ends of the synchronous shaft are meshed with the synchronous gears on it, which effectively avoids the horizontal deviation caused by the lifting cylinders on both sides driving the lifting of the upper pinch rollers at both ends, and can effectively ensure the horizontal performance of the upper pinch roller driven by the lifting cylinder, ensure the eccentric gap with the lower pinch roller, and better meet the pinching requirements. The calibration of the synchronous rack can be done by calibrating the consistency of both sides on the calibration seat through the calibration screw connected to it, and then locking and positioning with a nut, which further improves the lifting and lowering level stability of the upper pinch roller.

[0015] 3. When conveying some high-precision, stainless steel plates and strips, the upper and lower pinch rollers and adjusting rollers can adopt a roller structure with a rubber layer to ensure that the conveying part affects its surface performance; when conveying some hot materials and plates with low requirements on the plate surface, a steel roller structure can be directly used.
