Description

Technical Field

[0001] The invention relates to the technical field of stainless steel plate processing, and in particular to an unwinding machine for stainless steel plate processing. Background Art

[0002] At present, many stainless steel plate processing plants purchase coils directly from steel mills, and then cut the coils into flat plates of the size required by customers after flattening and polishing. Stainless steel coils are a type of rolled plate product made of stainless steel, which is corrosion-resistant, high-strength, beautiful, durable and easy to process. Stainless steel coils are usually used in the fields of construction, manufacturing, chemical, food processing and home appliances. The coils need to be unrolled before flattening. Unrolling stainless steel coils is the process of unfolding the rolled stainless steel plates. After unrolling, the stainless steel coils can be cut, stamped, bent and other processing operations, and are used to manufacture various stainless steel products, such as kitchen utensils, electrical appliance housings, building decoration materials, etc. When unrolling the stainless steel coils, they need to be opened and fixed from the center of the coils to adapt to coils with different center radii.

[0003] When the center of the coil is rigidly supported from the inside, a large internal support force is required to ensure the stability of the coil when it is unrolled, so that the coil will not slip when it is unrolled. When the inside of the coil is supported by the hard pressure for a long time, the coil is prone to deformation and even scratches and damage on the surface as the number of coil layers decreases. Therefore, we proposed an unwinding machine for stainless steel plate processing. Summary of the invention

The outer surface of the hollow cylinder is fixedly connected with the arc-shaped brush. Affected by the viscosity of the lubricating oil and the small diameter of the seepage hole, the arc-shaped brush soaked with lubricating oil will block the seepage hole when the stainless steel coil is not unwound, preventing the lubricating oil from continuously seeping out of the seepage hole to the outside when the stainless steel coil is not unwound, causing waste.

[0019] The present invention has the beneficial effects:

[0020] 1. The present invention converts the hard contact of pushing into elastic contact by arranging a frame-shaped rubber pad of elastic material between the inner supporting arc plate and the stainless steel coil, thereby preventing the inner side of the coil from being subjected to hard pressure for a long time. When the inner side is supported, the coil is prone to deformation as the number of coil layers decreases, and even scratches and damage may appear on the surface. Two annular push plates are used to push both sides of the stainless steel coil with equal force so that the center of the stainless steel coil is aligned with the center of the large roller, thereby preventing the stainless steel coil from being affected by external force and lateral deviation on the roller to affect the unwinding effect during unwinding. The hollow cylinder gradually approaches the stainless steel coil and presses the top and bottom of the stainless steel coil tightly, thereby preventing the stainless steel coil from being loosened due to the influence of the unwinding speed and the like during unwinding.

[0021] 2. The present invention provides an internal support device, and a frame-shaped rubber pad made of elastic material is provided between the internal support arc plate and the stainless steel coil plate to change the hard contact of pushing into elastic contact, so as to prevent the inner side of the coil plate from being subjected to hard pressure for a long time. When the inner side of the coil plate is supported internally, the coil plate is easily deformed as the number of coil plate layers decreases, and even scratches and damage may appear on the surface. The friction of the contact surface is increased by providing a frame-shaped rubber pad made of rubber material to fit in contact with the inner side surface of the stainless steel coil plate, so as to prevent the internal support arc plate with a relatively smooth surface from slipping when supporting the stainless steel coil plate. By providing a plurality of extension springs on the inner side of the frame-shaped rubber pad, it is convenient to adjust the different pushing forces of the frame-shaped rubber pad on the stainless steel coil plate, so as to prevent the internal support arc plate made of hard material from easily causing damage to the stainless steel coil plate or the internal support arc plate body when increasing the pushing force on the inner side of the stainless steel coil plate.

[0022] 3. The present invention provides a pushing device, and uses two annular pushing plates to push both sides of the stainless steel coil with equal force so that the center of the stainless steel coil is aligned with the center of the large winding roller, thereby preventing the stainless steel coil from being affected by external force and laterally deviating on the winding roller to affect the unwinding effect during unwinding. A retractable pushing spring is provided between the internal threaded ring plate and the annular pushing plate to apply pushing force, which facilitates pushing of stainless steel coils of different lengths and prevents difficulty in adapting when stainless steel coils of different lengths need to be pushed. A brush plate is provided in the trapezoidal hole to frictionally clean the two side surfaces of the unwound stainless steel coil, thereby preventing the two side surfaces of the stainless steel coil from being mixed with particles and debris and being damaged by friction in subsequent processing after unwinding. A large amount of particles and debris cleaned by the brush plate will be discharged to the side of the pushing spring through the trapezoidal hole, thereby preventing a large amount of cleaned particles and debris from being mixed between the annular pushing plate and the side surface of the stainless steel coil and causing extrusion damage to the stainless steel coil.

[0023] 4. The present invention provides a clamping mechanism, so that the hollow cylinder gradually approaches the stainless steel coil and clamps the top and bottom of the stainless steel coil, so as to prevent the stainless steel coil from being loosened due to the influence of the unwinding speed when unwinding. The end of the hollow cylinder close to the stainless steel coil is rounded to reduce its contact area, so as to prevent the end of the hollow cylinder from being in large-area pushing contact with the stainless steel coil and causing damage to the surface of the stainless steel coil. A seepage hole with a smaller aperture is provided on the surface of the hollow cylinder to facilitate the lubricating oil in the hollow cylinder to slowly penetrate out and lubricate and coat the hollow cylinder and the arc-shaped brush, so as to prevent the hollow cylinder and the arc-shaped brush from being damaged by scratches when the contact pressure with the surface of the stainless steel coil is too large. The arc-shaped brush soaked with lubricating oil will block the seepage hole due to the influence of the viscosity of the lubricating oil and the smaller aperture of the seepage hole when the stainless steel coil is not unwinding, so as to prevent the lubricating oil from continuously seeping out of the seepage hole to the outside when the stainless steel coil is not unwinding and causing waste.

A retractable pushing spring 605 is set between the internal threaded ring plate 602 and the annular push plate 606 to apply pushing force to facilitate pushing of stainless steel coils of different lengths. When the stainless steel coil is unwound, the two side surfaces will frictionally contact with the brush plate 608 on the inner wall of the trapezoidal hole 607 opened by the annular push plate 606. The brush plate 608 is set in the trapezoidal hole 607 to frictionally clean the two side surfaces of the unwound stainless steel coil, and a large amount of particulate debris cleaned by the brush plate 608 will be discharged to the side of the pushing spring 605 through the trapezoidal hole 607.After the stainless steel coil is fixed and pushed, the top and bottom can be clamped by the clamping mechanism 603, and the electric push rod 6031 pushes the curved connecting rod 6032 to move in the direction of the stainless steel coil. The movement of the curved connecting rod 6032 drives the hollow cylinder 6033 at one end to move, and the hollow cylinder 6033 gradually approaches the stainless steel coil and clamps the top and bottom of the stainless steel coil. The end of the hollow cylinder 6033 close to the stainless steel coil is set to a rounded corner to reduce its contact area, and a small seepage hole 6035 is opened on the surface of the hollow cylinder 6033 to facilitate the lubricating oil in the hollow cylinder 6033 to slowly penetrate the hollow cylinder 6033 and the arc brush. 6036 is used for lubrication coating. The dense arc brushes 6036 are arranged on the surface of the hollow cylinder 6033 near the seepage hole 6035. The lubricating oil that penetrates the hollow is soaked in the dense arc brushes 6036 and coated on the surrounding position of the stainless steel coil surface in contact with the hollow cylinder 6033 through the arc brushes 6036. Affected by the viscosity of the lubricating oil and the small aperture of the seepage hole 6035, when the stainless steel coil is not unrolled, the arc brushes 6036 soaked with lubricating oil will block the seepage hole 6035. After the lubricating oil in the hollow cylinder 6033 is used up, lubricating oil is added into it through the oil inlet pipe 6034. After the hollow cylinder 6033 is filled with lubricating oil, the oil inlet pipe 6034 is blocked.
