Description

Technical Field

[0001] The utility model relates to a device for preventing material jamming during continuous shearing of a flying shear. Background Art

[0002] The flying shear is used in the continuous heat treatment production line of aluminum alloy and can continuously shear aluminum strips without interruption. However, after the aluminum strip undergoes heat treatment, the residual stress is released, and the shape of the aluminum strip is poor, showing a downward-bent shape at the head. During continuous shearing, it will cause the aluminum strip to be inserted into the gap between the flying shear and the subsequent conveying belt, and it cannot reach the conveying belt smoothly, thus making it impossible for the flying shear to achieve continuous shearing smoothly. Content of the Utility Model

[0003] The purpose of the utility model is to provide a device for preventing material jamming during continuous shearing of a flying shear, which helps to avoid aluminum strip jamming and achieve continuous shearing.

[0004] The technical solution of the utility model lies in: a device for preventing material jamming during continuous shearing of a flying shear, including a flying shear frame. A front guide plate is arranged on the input side of the flying shear frame, and an anti-jamming guide plate frame is arranged on the output side of the flying shear frame. An adjusting mechanism for adjusting the front-end height of the anti-jamming guide plate frame to form an angle with the horizontal plane is arranged on the flying shear frame.

[0005] Further, a fixing frame is arranged on the output side of the flying shear frame, and the anti-jamming guide plate frame is installed on the fixing frame.

[0006] Further, the adjusting mechanism includes connecting shafts installed on both sides of the fixing frame. Fixing plates are arranged on both sides behind the flying shear frame. The outer ends of the connecting shafts are vertically fixed with adjusting plates whose lower ends are rotatably connected to the fixing plates. An arc-shaped groove is arranged on the upper part of the fixing plate, and a fixing screw longitudinally arranged in the arc-shaped groove and screwed with the adjusting plate is provided.

[0007] Further, the anti-jamming guide plate frame includes a longitudinal plate longitudinally installed on the upper side in front of the fixing frame, and guide plates extending backward out of the fixing frame are arranged at intervals along the longitudinal direction on the longitudinal plate.

[0008] Further, rotating shafts rotatably connected to the fixing frame are longitudinally arranged at the front and rear parts of the fixing frame. Synchronous belt wheels are fixed between the two guide plates on the rotating shafts, and a synchronous belt is wound around the corresponding two synchronous belt wheels on the front and rear sides.

[0009] Further, one end of the rotating shaft at the rear side passes through the fixing frame and is installed with a driving gear.

[0010] Further, a conveyor belt mechanism with adjustable rear-end height is arranged on the output side of the anti-jamming guide plate frame.

[0011] Furthermore, the conveyor belt mechanism includes a support frame, on which there is a conveyor belt rack rotatably connected to its front part and provided with a conveyor belt. An inclined hydraulic rod is hinged on the support frame, and the telescopic end of the hydraulic rod is hinged to the conveyor belt rack.

[0012] Compared with the prior art, the present utility model has the following advantages:

[0013] 1. If the aluminum belt bends severely downwards, the inclination angle of the anti-jamming guide plate frame can be adjusted through the adjustment mechanism, and the anti-jamming guide plate frame can be adjusted to form an angle of 25-30° with the aluminum belt. Then, the downward-bent strip can also be smoothly conveyed onto the anti-jamming guide plate frame and fed into the conveyor belt mechanism.

[0014] 2. The device is equipped with a conveyor belt (synchronous belt) on the anti-jamming guide plate frame, which rotates continuously driven by a motor. Once the aluminum belt is conveyed onto the anti-jamming guide plate frame, it is continuously conveyed forward driven by the conveyor belt equipped on the anti-jamming guide plate frame, and the head of the aluminum belt will not get stuck on the anti-jamming guide plate frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] To make the above features and advantages of the present utility model more understandable, specific embodiments are given below in conjunction with the accompanying drawings and described in detail as follows, but the present utility model is not limited thereto.

[0022] Reference Figures 1 to 5

[0023] A device for preventing material jamming during continuous shearing of a flying shear, including a flying shear frame 10. A strip feeding roller device for aluminum strip is arranged on the front side of the flying shear to feed the strip to the flying shear conveyor belt. A front guide plate 11 is arranged on the input side of the flying shear frame, and an anti-jamming guide plate frame 30 is arranged on the output side of the flying shear frame. An adjusting mechanism for adjusting the height of the front end of the anti-jamming guide plate frame to form an angle with the horizontal plane is arranged on the flying shear frame. When the anti-jamming guide plate frame is in the normal working state, it is at the same height as the front guide plate of the flying shear and is parallel to the strip. If the aluminum strip has a straight shape, it can be smoothly transported to the anti-jamming guide plate frame; if the aluminum strip bends severely downward, the inclination angle of the anti-jamming guide plate frame can be adjusted through the adjusting mechanism, and the anti-jamming guide plate frame can be adjusted to form an angle of 25-30° with the aluminum strip, and the downward-bent strip can also be smoothly transported to the anti-jamming guide plate frame and fed into the conveyor belt mechanism.

[0024] In this embodiment, a fixing frame 40 is arranged on the output side of the flying shear frame, and the anti-jamming guide plate frame is fixedly installed on the fixing frame. The anti-jamming guide plate frame includes a longitudinal plate 31 longitudinally installed on the upper side in front of the fixing frame. The longitudinal plate is provided with guide plates 32 extending backward out of the fixing frame at intervals along the longitudinal direction. The rear end of the fixing plate and the front end of the guide plate both have arc-shaped portions turning downward.

[0025] In this embodiment, in order to adjust the inclination angle of the anti-jamming guide plate frame, the adjusting mechanism includes connecting shafts 41 installed on both sides of the fixing frame. Fixing plates 12 are fixed on both sides at the rear of the flying shear frame. The outer ends of the connecting shafts are vertically fixed with adjusting plates 42 whose lower ends are rotatably connected to the fixing plates. An arc-shaped groove 13 is arranged in the upper part of the fixing plate to give space for adjusting the fixing screw; two fixing screws 14 longitudinally arranged in the arc-shaped groove and screwed to the upper part of the adjusting plate are used to fix the fixing frame, that is, to position the anti-jamming guide plate frame.

[0026] When it is necessary to adjust the angle of the anti-jamming guide plate frame, first loosen the fixing screw, use a crowbar to pry the adjusting plate to make the adjusting plate deflect, and when the angle reaches the required angle (25-30°), then re-tighten the fixing screw of the adjusting plate.

[0027] In this embodiment, in order to assist the aluminum strip falling on the anti-jamming guide plate frame to move forward, rotating shafts 43 rotatably connected to the fixing frame are longitudinally arranged at the front and rear parts of the fixing frame. Synchronous belt wheels 46 are fixed between the two guide plates on the rotating shafts. A synchronous belt 44 is wound around the two corresponding synchronous belt wheels on the front and rear sides. One end of the rotating shaft at the rear side passes through the fixing frame and is installed with a driving gear 45, which is continuously rotated by a motor through a chain. Once the aluminum strip is transported to the anti-jamming guide plate frame, it is continuously transported forward under the drive of the synchronous belt equipped on the anti-jamming guide plate frame, and the head of the aluminum strip will not be stuck on the anti-jamming guide plate frame.

[0028] In this embodiment, in order to facilitate the output of the cut aluminum strip into different processes, a conveyor belt mechanism with an adjustable rear height is provided on the output side of the anti-jamming guide plate frame. Specifically, the conveyor belt mechanism includes a support frame 21, on which a conveyor belt frame 23 is rotatably connected to the rear and is provided with a conveyor belt 22. An inclined hydraulic rod 24 is hinged on the support frame, and the telescopic end of the hydraulic rod is hinged to the conveyor belt frame, so as to realize the lifting of the front end of the conveyor belt mechanism.

[0029] If the present utility model discloses or involves components or structural parts that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connected by bolts or screws), or can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integral structure (for example, manufactured by integral casting process) (except when it is obviously impossible to adopt the integral forming process).

[0030] In addition, in any of the technical solutions disclosed by the present utility model, the terms used to represent the positional relationship or shape, unless otherwise stated, include states or shapes that are approximate, similar or close to it.

[0031] Any component provided by the present utility model can either be assembled from a plurality of separate components or be a single component manufactured by an integral forming process.

[0032] The above are only the preferred embodiments of the present utility model. All equivalent changes and modifications made according to the scope of the patent application of the present utility model shall fall within the scope covered by the present utility model.
