Description

Technical Field

[0001] The invention relates to the field of equipment for stainless steel strips, and in particular to a self-unloading stainless steel strip winding device and method. Background Art

[0003] For the convenience of storage and transportation, stainless steel strips need to be rolled into rolls after production and processing. This is to effectively reduce the floor space while avoiding damage such as creases. At present, the rolling of stainless steel strips is generally achieved using a winding device. The end of the stainless steel strip is fixed on the roller of the winding device, and then the roller is rotated to achieve the rolling process.

The embodiments described herein are only used to more clearly illustrate the technical solutions of the present invention, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present invention.

[0053] Embodiment: A self-unloading stainless steel strip winding device, such as Figure 1-Figure 2 As shown, it includes: a base 1; a back plate 101 fixedly mounted on the rear of the base 1; a roller 2 rotatably mounted on the back plate 101, the roller 2 is parallel to the horizontal plane, and the head and tail are oriented in the front-to-back direction, and the reel for winding the stainless steel strip will be inserted on the roller 2; a driving motor X201 fixedly mounted on the back plate 101, and the output end of the driving motor X201 is fixedly mounted on the roller 2 to drive the roller 2 to rotate and wind the stainless steel strip; a disc 202 fixedly mounted on the rear end of the roller 2, the base 1 is used to separate the back plate 101 and the stainless steel strip wound on the roller 2, so as to avoid friction between the stainless steel strip and the back plate 101 during the winding process, thereby reducing the wear of the stainless steel strip; a solid material component arranged on the roller 2 for fixing the reel; a discharging component arranged on the base 1 for discharging the stainless steel strip roll that has been wound; a cutting component arranged on the base 1 for cutting the stainless steel strip.

[0054] Put the reel on the roller 2, control the solid material component to fix the reel, and then fix the end of the stainless steel strip on the reel; after completion, start the drive motor X201, control the roller 2 to rotate, and reel the stainless steel strip on the reel. After reeling a certain length of the stainless steel strip, turn off the drive motor X201, control the solid material component to release the reel, and the stainless steel strip will fall on the unloading component. At the same time, the cutting component cuts the stainless steel strip and separates this part of the stainless steel strip that has been rolled. Finally, control the unloading component to transport the stainless steel strip forward to separate the stainless steel strip from the roller 2, and the unloading of the stainless steel strip is completed.

[0055] like Figure 5-Figure 6 As shown, the solid material assembly includes: a support plate 3 slidably mounted on the curved side wall of the roller shaft 2, four support plates 3 are provided, and are arranged around the roller shaft 2 at equal intervals; a screw 301 rotatably mounted in the roller shaft 2, and two sections of threads are provided on the screw 301, and the lines of the two sections of threads are arranged in opposite directions; a driving motor Y302 fixedly mounted on the front end of the roller shaft 2, and the output end of the driving motor Y302 is fixed to the screw 301 to drive the screw 301 to rotate; a mounting ring 303 threadedly mounted on the screw 301, and two mounting rings 303 are provided, which are respectively arranged on the two sections of threads of the screw 301; a connecting arm 304 rotatably mounted between the mounting ring 303 and the support plate 3, and each support plate 3 and the two mounting rings 303 are provided with a connecting arm 304.

[0056] Start the driving motor Y302. When it controls the screw 301 to rotate forward, the screw 301 will separate the two mounting rings 303 from each other, and the angle between the connecting arm 304 and the screw 301 will become smaller. Then the connecting arm 304 will drive the support plate 3 to move toward the direction close to the screw 301, that is, the support plate 3 is controlled to be retracted relative to the roller shaft 2. Conversely, when it controls the screw 301 to rotate reversely, the support plate 3 is controlled to be expanded relative to the roller shaft 2. Therefore, the solid material component fixes and loosens the roll by changing the size of the circle surrounded by the support plate 3.

[0057] like Figure 3-Figure 4 As shown, the unloading assembly includes: a slide rail 401 fixedly mounted on the base 1, the slide rail 401 is located below the roller shaft 2, and its head and tail direction is set to the front and rear direction; a sliding seat 402 slidably mounted on the slide rail 401, and four guide sleeves 404 are arranged on the sliding seat 402; a receiving platform 4, and four guide pillars 403 are arranged at the bottom of the receiving platform 4, and each guide pillar 403 is slidably mounted in each guide sleeve 404, so that the receiving platform 4 is slidably mounted on the sliding seat 402, and the upper part of the receiving platform 4 is set to a V shape to limit the position of the stainless steel strip on the receiving platform 4, thereby ensuring that the receiving platform 4 can stably support the stainless steel strip roll; a reset spring 405 sleeved on the guide pillar 403, one end of the reset spring 405 is fixed to the guide sleeve 404, and the other end is fixed to the guide pillar 403, The positioning spring 405 can buffer the stainless steel strip roll; the limiting groove 406 fixedly installed above the slide rail 401; the convex strips 407 fixedly installed on both sides of the receiving platform 4, the convex strips 407 can cooperate with the limiting grooves 406, so that the receiving platform 4 can be slidably installed on the limiting grooves 406; the screw rod 408 rotatably installed on the base 1; the driving motor Z409 fixedly installed on the rear side of the back plate 101, the output end of the driving motor Z409 is fixedly installed with the screw rod 408 to drive the screw rod 408 to rotate; the half sleeve 410 fixedly installed at the bottom of the receiving platform 4, the half sleeve 410 is provided with a thread, after the half sleeve 410 contacts with the screw rod 408, the two will be able to threadably cooperate, so that the screw rod 408 rotates through the half sleeve 410 to control the movement of the receiving platform 4.

[0058] After the stainless steel coil is wound up and needs to be unloaded, the solid material assembly is controlled to retract the support plate 3, so that the support height of the stainless steel coil by the support plate 3 is reduced, and the stainless steel coil is moved downward. Then the stainless steel coil will contact with the receiving platform 4, and in the process of continuous downward movement, its support position is changed from the support plate 3 to the receiving platform 4, and at the same time, the receiving platform 4 slides downward, and the reset spring 405 is compressed. The reset spring 405 also buffers the stainless steel coil to avoid indentations on the stainless steel coil as much as possible; until the reset spring 405 is deformed to its limit position, the receiving platform 4 stops moving, at this time, the reel in the middle of the stainless steel coil is separated from the roller 2 and the support plate 3, and at the same time, the half sleeve 410 is moved to contact and cooperate with the screw rod 408; finally, the drive motor Z409 is started, and the half sleeve 4 is used to move the stainless steel coil to the receiving platform 4. 10 cooperates with the screw rod 408 to move the sliding seat 402, the receiving platform 4 and the stainless steel strip roll thereon forward, so that the stainless steel strip roll is separated from the roller shaft 2, and the stainless steel strip roll is unloaded. After that, the stainless steel strip roll can be conveniently transported or stored in the next step; during the movement of the receiving platform 4, the convex strip 407 will slide into the limiting groove 406, restricting the receiving platform 4 from moving upward. Therefore, afterwards, when the stainless steel strip roll is separated from the receiving platform 4, the receiving platform 4 will not be directly reset upward by the reset spring 405, but after the sliding seat 402 and the receiving platform 4 are reset backward, so that the convex strip 407 is separated from the limiting groove 406, the receiving platform 4 can be reset upward by the reset spring 405, and the receiving platform 4 also moves to the bottom of the roller shaft 2, so that the receiving platform 4 can unload again.

[0059] like Figure 7-Figure 8 As shown, the cutting assembly includes: a mounting plate 501 fixedly mounted on the left side of the base 1, and an opening is provided on the mounting plate 501 for the stainless steel belt to pass through; a cutter 5 slidably mounted on the mounting plate 501, the cutter 5 is located below the opening, and the blade of the cutter 5 is tilted in a manner of high at the front and low at the back; a fixed knife 502 fixedly mounted on the mounting plate 501, the fixed knife 502 is located above the opening, and the blade of the fixed knife 502 is tilted in a manner of low at the front and high at the back, so that the distance between the front ends of the cutter 5 and the fixed knife 502 is smaller than the distance between the rear ends thereof; a bracket fixedly mounted on the base 1 503, the bracket 503 is located between the mounting plate 501 and the receiving platform 4; the rotating frame 504 rotatably mounted on the bracket 503; the fixed frame 505 fixedly mounted on the cutter 5, the fixed frame 505 and the left end of the rotating frame 504 are slidably mounted; the hook bar 506 fixedly mounted on the left end of the receiving platform 4, the right end of the rotating frame 504 is against the hook bar 506, through the cooperation of the hook bar 506 and the rotating frame 504, the receiving platform 4 is moved downward to control the cutter 5 to move upward, and the right end of the rotating frame 504 is set to a columnar shape, so that the right end of the rotating frame 504 can better rotate relative to the hook bar 506.

[0060] Before fixing the end of the stainless steel strip on the reel, the end of the stainless steel strip is passed through the opening on the mounting plate 501; when the solid material assembly releases the reel and the stainless steel strip roll is moved down to the receiving platform 4 and supported by the receiving platform 4, the receiving platform 4 moves down and controls the right end of the rotating frame 504 to move down through the hook bar 506, thereby causing the rotating frame 504 to rotate, and then the left end of the rotating frame 504 moves up, and then the cutter 5 is moved up through the fixed frame 505, that is, the cutter 5 approaches the direction of the fixed knife 502, and the cutter 5 can cooperate with the fixed knife 502 to cut the stainless steel strip, and the blades of the cutter 5 and the fixed knife 502 are inclined so that they cooperate with each other to cut the stainless steel strip from front to back in sequence, so that the cutting assembly can better achieve cutting and improve the cutting effect.
