Description

TECHNICAL FIELD

[0001] The utility model belongs to strip steel winding technology field relates to a coiler guide plate device. BACKGROUND

[0002] In the strip steel production process, the strip steel needs to be wound after processing in order to facilitate packaging and transportation. The existing strip steel winding equipment usually includes one or more guide plates for guiding the strip steel to be smoothly wound on the winding drum. However, the existing guide plate device has some problems and deficiencies.

[0003] For example, the existing guide plate device usually adopts a fixed inclination angle, which cannot adapt to the angle formed by the winding drum and the rotating shaft on the strip steel winding equipment of different specifications. This leads to the fact that the guide plate cannot be used and the range of use is limited. Especially in the hot galvanizing process, when the tail of the strip steel reaches the exit guide plate, the falling phenomenon is easy to occur, thereby causing damage to the tail of the strip steel, especially for thin plates. This not only reduces the quality of the product, but also reduces the yield. SUMMARY

[0004] Therefore, the purpose of the utility model is to provide a coiler guide plate device to solve the problem of fixed angle of the guide plate in the existing strip steel winding equipment, which cannot adapt to the angle difference between the winding drum and the rotating shaft of different specifications, and the falling phenomenon of the tail of the strip steel in the hot galvanizing process, which causes damage to the tail of the strip steel and reduces the quality of the product and the yield.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0006] A coiler guide plate device, comprising a frame, the frame is rotatably arranged around a steering roller fixedly arranged, and the rotation angle thereof is adjusted by a first oil cylinder connected thereto; a swing guide plate is arranged on the side of the frame away from the steering roller, and the swing guide plate is elongated or retracted along the length direction of the frame by a second oil cylinder.

[0007] Optionally, the swing guide plate is connected to the end of the frame in a hinged manner, and the swing guide plate is driven to rotate around the frame by the second oil cylinder.

[0008] Optionally, drive roller assemblies and driven roller assemblies are arranged at both ends of the frame, and the drive roller assemblies and the driven roller assemblies are connected by a belt.

[0009] Optionally, a magnet is arranged between the drive roller assembly and the driven roller assembly for pressing the strip steel against the frame.

[0010] Optionally, the coiler guide plate device is used in cooperation with a coiler core, and the stroke range of the frame guided by the first oil cylinder covers the high position and the low position of the coiler core shaft.

[0011] The utility model discloses the beneficial effect lies in:

[0012] The flexibility of the equipment is improved: by using two oil cylinders and the design of swing guide plates, the position of the guide plate can be adjusted according to different specifications of the coiler mandrel, so that the equipment can adapt to more kinds of strip coiling requirements.

[0013] The product quality is improved: the original sliding guide mode is replaced by the magnetic belt guide mode, which significantly reduces the scratches on the head and tail of the coiled strip before the building-up, thereby improving the appearance quality and internal quality of the product.

[0014] The yield is improved: the strip is guided by the magnetic adsorption mode, which avoids the wrinkles and scratches of the tail caused by the weight falling after the tail comes out of the turning pinch roll, thereby reducing the scrap rate and improving the yield.

[0015] The use range is expanded: the design of the scheme allows the equipment to realize automatic coiling diameter control of the strip during coiling, so that the equipment can adapt to strips of different thickness and width, thereby expanding the use range of the equipment.

[0016] The reliability of the equipment is improved: by adopting the magnetic belt guide mode, the failure rate of the equipment during coiling is reduced, and the reliability and stability of the equipment are improved.
