Description

Technical Field

[0001] This invention relates to the technical field of auxiliary processing devices for stainless steel strips, and in particular to an automatic feeding device for stainless steel strips. Background Technology

[0002] In the automated processing of steel strip, the feeding operation is a fundamental step in achieving continuous production. Since steel strip is currently generally stored in coil form, its outermost end needs to be accurately and stably fed into the processing device, a process that usually relies on an automatic feeding device.

[0003] However, due to the large overall weight of the steel strip coil, during the actual unwinding process, the traction mechanism of the feeding device needs to overcome a large rotational inertia when pulling the end of the steel strip. The traction force acts directly on the steel strip, which can easily cause damage to the steel strip. In addition, during the traction process, the clamping mechanism of the feeding device and the steel strip often slip relative to each other due to force fluctuations, which causes deviations in the feed position of the steel strip, thereby affecting the feeding accuracy and the consistency of subsequent processing. Summary of the Invention

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0027] Example: An automatic stainless steel strip feeding device, such as Figure 1 , Figure 2 and Figure 5As shown, it includes: a frame 1, which consists of a base 101 at the bottom and a support frame 102 fixed on the base 101, wherein the base 101 is provided with a track 103 for the material loading trolley to travel on. like Figures 1-4 As shown, the device also includes two sets of feeding units 2 disposed on the base 101, which are used to rotate the steel coil to actively feed out the steel strip 002. Each feeding unit 2 includes: a support base 201 fixedly mounted on a base 101; two sets of mounting arms 202 are rotatably mounted on the upper part of the support base 201, and U-shaped portions 202a are provided at the ends of the mounting arms 202. The U-shaped portions 202a of the two mounting arms 202 work together to support the roller core 001 of the steel coil; two sets of rotating wheels 203 are rotatably mounted in each U-shaped portion 202a, and the roller core 001 supported by the U-shaped portion 202a is driven to rotate by the rotation of the rotating wheels 203; a first motor 204 is fixedly mounted on each mounting arm 202; the output end of the first motor 204 is connected to each rotating wheel 203 by a first synchronous belt group 205; the two ends of each U-shaped portion 202a are connected to the roller core 001. A mounting block 206 is slidably mounted on the side; an auxiliary wheel 207 is rotatably mounted on each mounting block 206; a return spring 208 is sleeved on the sliding part of the mounting block 206, and the two ends of the return spring 208 are fixedly connected to the mounting block 206 and the U-shaped part 202a respectively; a first electric push rod 209 is rotatably mounted on the support base 201 via a bracket; a first connecting block 209a is fixedly mounted on the end of the first electric push rod 209; a first hinge shaft 210 is fixedly mounted on the arm body of the mounting arm 202, and the first connecting block 209a is rotatably connected to the first hinge shaft 210; a top frame 211 is fixedly mounted on the lower part of the support base 201, and the end of the top frame 211 is set as an arc surface structure that fits the surface of the roller core 001.

[0028] The working principle of this device is as follows: First, the mounting arm 202 is controlled to rotate downwards, and the loading trolley carrying the steel coil is controlled to move between the two mounting arms 202. Then, the mounting arm 202 is rotated in the opposite direction, so that the U-shaped part 202a of the mounting arm 202 supports the roller core 001, thereby removing the entire steel coil from the loading trolley. After loading is completed, the loading trolley is driven away from the device. During the contact between the mounting arm 202 and the roller core 001, the auxiliary wheel 207 is pressed away from the center of the roller core 001 after contacting it. The return spring 208 is compressed accordingly, and its return tendency acts on the roller core 001, so that the roller core 001 is stably loaded between the mounting arms 202 and keeps in contact with the rotating wheel 203. Finally, the first motor 204 is started, which drives the rotating wheel 203 to rotate continuously, thereby driving the roller core 001 to rotate, thereby realizing the active release of the steel strip 002.

[0029] When the steel strip 002 has been completely discharged and only the roller core 001 remains on the feeding unit 2, the mounting arm 202 is controlled to rotate downwards, causing the roller core 001 to move to contact the top frame 211. After the arc structure of the top frame 211 contacts the roller core 001, the rotational displacement of the mounting arm 202 pushes the roller core 001 to detach from the mounting arm 202, thereby realizing the automatic unloading of the roller core 001 and improving the ease of operation of this device.

[0030] like Figure 1 , Figure 5 and Figure 6 As shown, the device also includes two sets of feeding units 3 set on the support frame 102 for conveying steel strip 002 to the external steel strip processing device. Each feeding unit 3 is correspondingly set on the steel strip 002 discharge side of each discharging unit 2. Each feeding unit 3 includes: a mounting frame 301 fixedly mounted on a support frame 102; two sets of first transport wheels 302 rotatably mounted on the lower layer of the mounting frame 301; a support block 303 slidably mounted on the upper layer of the mounting frame 301 in the vertical direction; two sets of second transport wheels 304 rotatably mounted between the support blocks 303, each set of second transport wheels 304 corresponding to each set of first transport wheels 302; two sets of second motors 305 fixedly mounted on the support blocks 303, the output ends of the two sets of second motors 305 being coaxially fixed to the two second transport wheels 304 respectively; and a support block 303 slidably mounted on the mounting frame 301. A first cylinder 306 is fixedly installed, and the end of the telescopic rod of the first cylinder 306 is fixedly connected to the support block 303 for driving the adjustment of the distance between the second transport wheel 304 and the first transport wheel 302; a pallet 307 is rotatably installed on the side of the mounting frame 301 near the feeding unit 2; a second electric push rod 308 is rotatably installed below the mounting frame 301 via a bracket; a second connecting block 308a is fixedly installed at the end of the rod of the second electric push rod 308; a second hinge shaft 309 is fixedly installed below the pallet 307, and the second connecting block 308a is rotatably connected to the second hinge shaft 309.

[0031] Before the steel strip 002 is fed into the feeding unit 3, the first cylinder 306 is controlled to move the second transport wheel 304 upward, so that the first transport wheel 302 and the second transport wheel 304 are separated from each other, so as to facilitate the subsequent feeding of the steel strip 002. Then, after the unloading unit 2 actively releases the steel strip 002, the end of the steel strip 002 is fed into the space between the first transport wheel 302 and the second transport wheel 304 under the guidance of the pallet 307. Then, the second electric push rod 308 is started to move the second transport wheel 304 downward, so that the first transport wheel 302 and the second transport wheel 304 clamp the steel strip 002. Then, the second motor 305 is started to drive the second transport wheel 304 to rotate. With the auxiliary transport function of the first transport wheel 302, the steel strip 002 is stably oriented and automatically fed under the condition of continuous release.

[0032] As the steel strip 002 is continuously fed and the diameter of the steel coil gradually decreases, the angle between the steel strip 002 and the mounting frame 301 changes, causing the steel strip 002 to adhere to the pallet 307 and generate significant friction. Therefore, after the steel strip 002 is fed between the first transport wheel 302 and the second transport wheel 304, this device controls the second electric push rod 308 to retract its end, causing the pallet 307 to rotate downwards and retract. This avoids significant friction between the pallet 307 and the steel strip 002, thereby ensuring the automatic feeding speed of the steel strip 002 and reducing wear.

[0033] In summary, this device achieves automatic feeding of steel strip 002 through the cooperation of feeding unit 2 and feeding unit 3, avoiding the damage and feeding deviation caused by traction of the end of steel strip 002 in the traditional method. At the same time, by adding two sets of feeding units 2 and feeding units 3 to achieve alternating operation, the problem of interruption of external processing device operation caused by the time consumption of steel coil feeding and roller core 001 unloading is avoided, which significantly improves the continuity and efficiency of automatic feeding operation.

[0034] like Figure 1 , Figure 7 and Figure 8 As shown, the device also includes a transition unit 4 disposed on the support frame 102. The transition unit 4 is disposed between the two sets of feeding units 3 and is used to pull the steel strip 002, pulling the steel strip 002 on the feeding unit 3 on the side of the two sets of feeding units 3 that is far away from the external steel strip processing device to the feeding unit 3 on the side that is closer to it. The transition unit 4 includes: a material transfer frame 401 slidably mounted on the support frame 102; a fixing strip 402 slidably mounted on the material transfer frame 401; a second cylinder 403 fixedly mounted on the material transfer frame 401, the end of the telescopic rod of the second cylinder 403 being fixedly connected to the fixing strip 402 for driving the fixing strip 402 to move so that it cooperates with the material transfer frame 401 to clamp the steel strip 002; two threaded rods 404 rotatably mounted on the support frame 102, each threaded rod 404 being threadedly engaged with the material transfer frame 401; a third motor 405 fixedly mounted on the support frame 102, the output end of the third motor 405 being coaxially fixed with one of the threaded rods 404; and the two threaded rods 404 being connected by a second synchronous belt group 406.

[0035] After the steel strip 002 in the left feeding unit 2 is fed, the third motor 405 is started to drive the threaded rod 404 to rotate, so that the transfer frame 401 and the fixing bar 402 clamp the steel strip 002 and move it to the feeding side of the left feeding unit 3. Then the right feeding unit 2 and the two sets of feeding units 3 can be started to start the automatic feeding operation of the steel strip 002.

[0036] This device uses a transition unit 4 to achieve intermediate traction of the steel strip 002 between different workstations, so that the feeding unit 2 and the feeding unit 3, which are located far apart, can also smoothly and stably complete the automatic feeding of the steel strip 002, further improving the continuity and reliability of the feeding process of this device.

[0037] like Figure 1 and Figure 9 As shown, the device also includes two sets of limiting units 5 installed on the support frame 102, which are used to limit the position of the steel strip 002 in the initial stage of feeding the steel strip 002 to prevent the steel strip 002 from becoming loose. The two sets of limiting units 5 are respectively located directly above each feeding unit 2. Each set of limiting units 5 includes: a support frame 501 fixedly installed on the support frame 102; a pressing block 502 slidably disposed on the support frame 501 in the vertical direction; a pressing wheel 503 rotatably installed between the pressing blocks 502; a third cylinder 504 fixedly installed on the support frame 501, the telescopic end of the third cylinder 504 being fixedly connected to the pressing block 502, for driving the pressing wheel 503 to move, so as to limit the position of the steel strip 002 on the steel coil.

[0038] During the normal storage phase, the steel coil is kept in a coiled state by a fixing device. Once the steel coil is fed to the unloading unit 2, the fixing device needs to be removed for subsequent unloading. To prevent the steel strip 002 from loosening before entering the stable automatic feeding operation, this device uses a limiting unit 5 to temporarily limit the steel coil. Specifically, the third cylinder 504 drives the pressing wheel 503 downwards, bringing it into contact with the upper surface of the steel coil, thereby maintaining the overall coiled shape and ensuring the stability of the steel strip 002 when it enters the feeding unit 3. When the unloading unit 2 begins to release the steel strip 002, the pressing wheel 503 rotates synchronously without affecting the normal release of the steel strip 002. Once the steel strip 002 is stably conveyed by the feeding unit 3, the limiting function is released, and the pressing wheel 503 is moved upwards to reset.

[0039] This device, by setting a limiting unit 5, effectively limits the steel strip 002 after the steel coil fixing device is removed and before the automatic feeding is started, avoiding feeding problems or jamming caused by the loose steel strip 002, and ensuring the stability and reliability of the device in the initial feeding stage.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
