Description

Technical Field

[0001] This utility model relates to the field of rolling mill technology, and in particular to a cold rolling mill device that facilitates material unloading. Background Technology

[0002] A cold rolling mill is a device used to process metal materials (such as steel and aluminum) into coiled products through a cold rolling process. During the cold rolling process, the metal material is rolled by multiple rollers at room temperature, which reduces its thickness and increases its strength. Cold rolling mills are mainly used to produce thin plates, thin strips, steel coils and other products, and are widely used in the automotive, home appliance, construction, and electronics industries. Compared with hot rolling, cold-rolled products have higher precision, better surface quality and higher mechanical properties. The working principle of a cold rolling mill is to continuously compress the metal material through the pressure between the rollers, and to perform multiple rolling passes to gradually achieve the required thickness and performance requirements.

[0003] In the operation of existing cold rolling coil machines, the unloading of the wound coils still relies on manual or semi-automatic methods, which is slow and affects production efficiency. At the same time, the coils may be scratched, crushed or deformed due to uneven clamping force of the equipment or unsmooth unloading process, which affects product quality. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a cold rolling coil machine device with convenient unloading.

[0005] This utility model is achieved by the following technical solution: a cold rolling coil machine device with convenient unloading, including a main body, a winding mechanism is provided on the top of the main body, an unloading mechanism is provided on the inner wall of the main body, and a reinforcing rib plate is fixedly connected to the top of the main body; The winding mechanism includes a support frame, a fixed frame is fixedly connected to the surface of the support frame, a motor is fixedly connected to the inner wall of the fixed frame, a winding roller shaft is fixedly connected to the output end of the motor, a winding roller sleeve is slidably connected to the surface of the winding roller shaft, and a bearing is fixedly connected to the surface of the winding roller shaft.

[0006] The above technical solution involves setting up a take-up roller sleeve, which is installed on the surface of the take-up roller shaft. The motor is started to drive the take-up roller shaft to rotate on the inner wall of the support frame, thereby driving the take-up roller sleeve to take up the cold-rolled steel strip. After the take-up is completed, the take-up roller sleeve is slid off the surface of the take-up roller shaft to unload the cold-rolled steel coil. This reduces manual operation, avoids personnel injury, improves the safety of the device, increases the unloading efficiency, and enhances the practicality of the device.

[0007] As a further improvement to the above solution, the bottom of the support frame is fixedly connected to the top of the main body, and the surface of the reinforcing rib is fixedly connected to the surface of the support frame.

[0008] As a further improvement to the above solution, the inner wall of the fixing frame is rotatably connected to the surface of the take-up roller shaft.

[0009] As a further improvement to the above solution, the unloading mechanism includes an unloading hopper, a hydraulic lifting rod fixedly connected to the inner wall of the unloading hopper, a support arc plate fixedly connected to the output end of the hydraulic lifting rod, a buffer tube fixedly connected to the surface of the unloading hopper, a buffer groove opened on the inner wall of the main body, a spring fixedly connected to the inner wall of the buffer groove, a positioning rod fixedly connected to the inner wall of the buffer groove, a hydraulic push rod fixedly connected to the inner wall of the main body, a limit block fixedly connected to the surface of the unloading hopper, an auxiliary wheel rotatably connected to the inner wall of the unloading hopper, and a hydraulic support frame fixedly connected to the surface of the unloading hopper.

[0010] Through the above technical solution, by setting auxiliary wheels, when the hydraulic push rod pushes the unloading bucket to move outward from the main body, the auxiliary wheels roll on the ground to support the unloading bucket, preventing the device from tipping over due to instability of the center of gravity when the unloading bucket moves out, thus ensuring the reliability of the device.

[0011] As a further improvement to the above solution, the surface of the unloading hopper is slidably connected to the inner wall of the main body, the surface of the limiting block is slidably connected to the inner wall of the main body, and the surface of the supporting arc plate is slidably connected to the inner wall of the unloading hopper.

[0012] The above technical solution involves setting up a support arc plate, which is then lifted by a hydraulic lifting rod. The top of the support arc plate is in contact with the surface of the cold-rolled steel coil, providing support for the coil to be unloaded and avoiding excessive weight on the winding roller bearings. This facilitates the disassembly of the cold-rolled steel coil. During winding, the hydraulic lifting rod controls the support arc plate to be stored inside the unloading hopper, without affecting the winding of the cold-rolled steel strip.

[0013] As a further improvement to the above solution, the surface of the buffer tube is slidably connected to the inner wall of the buffer groove, the inner wall of the buffer tube is slidably connected to the surface of the positioning rod, and the output end of the hydraulic push rod is fixedly connected to the surface of the unloading bucket.

[0014] The above technical solution, by setting a spring, allows the buffer tube to squeeze the spring during the unloading bucket recovery. The spring contracts under force, buffering the unloading bucket and preventing it from directly impacting the main body. This avoids damage to the device structure caused by impact and improves the reliability of the device.

[0015] As a further improvement to the above solution, the top of the hydraulic support frame is in contact with the surface of the bearing.

[0016] Through the above technical solution, by setting up a hydraulic support frame, the top of the hydraulic support frame contacts the surface of the bearing during winding, assisting the support frame in bearing the load. When the support arc plate bears the load on the cold-rolled steel coil, the hydraulic support frame descends, making it easier for the winding roller sleeve to disengage from the surface of the winding roller shaft, thus improving the practicality of the device.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention features a winding mechanism, specifically a winding roller sleeve mounted on the surface of a winding roller shaft. A motor is started to rotate the winding roller shaft within the support frame, causing the winding roller sleeve to wind up the cold-rolled steel strip. After winding, the winding roller sleeve is slidably removed from the surface of the winding roller shaft to unload the cold-rolled steel coil. This reduces manual operation, prevents injuries, improves device safety, increases unloading efficiency, and enhances the device's practicality.

[0018] This invention features an unloading mechanism, specifically a supporting arc plate. A hydraulic lifting rod raises the supporting arc plate, whose top contacts the surface of the cold-rolled steel coil, bearing the weight of the coil to be unloaded and avoiding excessive load on the winding roller bearings. This facilitates disassembly of the cold-rolled steel coil. During winding, the hydraulic lifting rod controls the supporting arc plate to retract inside the unloading hopper, without affecting the winding of the cold-rolled steel strip. A spring is incorporated; during the unloading hopper's retraction, a buffer tube compresses the spring, causing it to contract and cushion the impact, preventing the unloading hopper from directly colliding with the main body. To prevent damage from impacts to the device structure and improve its reliability, auxiliary wheels are installed. When the hydraulic push rod moves the unloading bucket outward, the auxiliary wheels roll on the ground to support the bucket and prevent it from tipping over due to instability. This ensures the device's reliability. A hydraulic support frame is also installed. During winding, the top of the hydraulic support frame contacts the bearing surface, assisting in load-bearing. When the support arc plate supports the cold-rolled steel coil, the hydraulic support frame descends, facilitating the removal of the winding roller sleeve from the surface of the winding roller shaft, thus improving the device's practicality.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

The winding mechanism 2 includes a support frame 201, a fixed frame 202 fixedly connected to the surface of the support frame 201, a motor 203 fixedly connected to the inner wall of the fixed frame 202, a winding roller shaft 204 fixedly connected to the output end of the motor 203, and a winding roller sleeve 205 slidably connected to the surface of the winding roller shaft 204. The winding roller sleeve 205 is installed on the surface of the winding roller shaft 204. The motor 203 is started to drive the winding roller shaft 204 to rotate on the inner wall of the support frame 201, thereby driving the winding roller sleeve 205 to wind up the cold-rolled steel strip. After winding is completed, the winding roller sleeve 205 is slidably removed from the surface of the winding roller shaft 204 to unload the cold-rolled steel coil. This reduces manual operation, avoids personnel injury, improves device safety, and increases unloading efficiency. A bearing 206 is fixedly connected to the surface of the winding roller shaft 204.

[0023] The bottom of the support frame 201 is fixedly connected to the top of the main body 1, and the surface of the reinforcing rib plate 4 is fixedly connected to the surface of the support frame 201.

[0024] The inner wall of the fixed frame 202 is rotatably connected to the surface of the take-up roller shaft 204.

[0025] The unloading mechanism 3 includes an unloading bucket 301. A hydraulic lifting rod 302 is fixedly connected to the inner wall of the unloading bucket 301. A support arc plate 303 is fixedly connected to the output end of the hydraulic lifting rod 302. A buffer tube 304 is fixedly connected to the surface of the unloading bucket 301. A buffer groove 305 is opened on the inner wall of the main body 1. A spring 306 is fixedly connected to the inner wall of the buffer groove 305. A positioning rod 307 is fixedly connected to the inner wall of the buffer groove 305. A hydraulic push rod 308 is fixedly connected to the inner wall of the main body 1. A limit block 309 is fixedly connected to the surface of the unloading bucket 301. An auxiliary wheel 310 is rotatably connected to the inner wall of the unloading bucket 301. When the hydraulic push rod 308 pushes the unloading bucket 301 to move to the outside of the main body 1, the auxiliary wheel 310 rolls on the ground to support the unloading bucket 301 and prevent the device from tipping over due to instability when the unloading bucket 301 moves out. A hydraulic support frame 311 is fixedly connected to the surface of the unloading bucket 301.

[0026] The surface of the unloading hopper 301 is slidably connected to the inner wall of the main body 1, the surface of the limiting block 309 is slidably connected to the inner wall of the main body 1, and the surface of the supporting arc plate 303 is slidably connected to the inner wall of the unloading hopper 301. The supporting arc plate 303 is driven to rise by the hydraulic lifting rod 302. The top of the supporting arc plate 303 is in contact with the surface of the cold-rolled steel coil to bear the weight of the cold-rolled steel coil to be unloaded, avoiding the bearing of the winding roller shaft 204, and facilitating the disassembly of the cold-rolled steel coil. When winding, the hydraulic lifting rod 302 controls the supporting arc plate 303 to be stored inside the unloading hopper 301, which does not affect the device's winding of the cold-rolled steel strip.

[0027] The surface of the buffer tube 304 is slidably connected to the inner wall of the buffer groove 305, and the inner wall of the buffer tube 304 is slidably connected to the surface of the positioning rod 307. When the unloading bucket 301 is retracted, the buffer tube 304 compresses the spring 306, and the spring 306 is compressed by force to buffer the unloading bucket 301, so as to avoid the unloading bucket 301 directly hitting the main body 1 and avoid damage to the device structure due to impact. The output end of the hydraulic push rod 308 is fixedly connected to the surface of the unloading bucket 301.

[0028] The top of the hydraulic support frame 311 is in contact with the surface of the bearing 206. During winding, the top of the hydraulic support frame 311 contacts the surface of the bearing 206, and the auxiliary support frame 201 bears the load. When the support arc plate 303 bears the load on the cold-rolled steel coil, the hydraulic support frame 311 descends, making it easier for the winding roller sleeve 205 to disengage from the surface of the winding roller shaft 204.

[0029] The implementation principle of a convenient unloading cold-rolled coil mill device in this application embodiment is as follows: During use, the take-up roller sleeve 205 is installed on the surface of the take-up roller shaft 204. Then, the hydraulic support frame 311 rises and contacts the bearing 206. The hydraulic lifting rod 302 controls the support arc plate 303 to be housed inside the unloading hopper 301. The motor 203 is started to drive the take-up roller shaft 204 to rotate on the inner wall of the support frame 201, causing the take-up roller sleeve 205 to wind up the cold-rolled steel strip. After winding, the hydraulic lifting rod 302 drives the support arc plate 303 to rise. The top of the support arc plate 303 is in contact with the surface of the cold-rolled steel coil, bearing the weight of the cold-rolled steel coil to be unloaded, thus avoiding the weight of the take-up roller shaft 204. Then, the hydraulic support frame 311 descends to facilitate the winding roller... As sleeve 205 detaches from the surface of take-up roller shaft 204, and hydraulic push rod 308 is activated to drag unloading bucket 301 to the outside of main body 1, auxiliary wheel 310 rolls on the ground to support unloading bucket 301 and prevent the device from tipping over due to instability when unloading bucket 301 moves out. Cold-rolled steel coil and take-up roller sleeve 205 are removed from the surface of take-up roller shaft 204 together. Then, forklift transports the cold-rolled steel coil away, and take-up roller sleeve 205 is installed on take-up roller shaft 204. Hydraulic push rod 308 controls unloading bucket 301 to retract into the interior of main body 1. Buffer tube 304 compresses spring 306, and spring 306 contracts under force to buffer unloading bucket 301, preventing unloading bucket 301 from directly impacting main body 1 and avoiding damage to the device structure due to impact.
