[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a feeding device for hot-rolled stainless steel coil, comprising: two support frames 1, a conveying component 2 arranged on the inner side of the two support frames 1, upright plates 102 fixedly connected to both ends of the top of the two support frames 1, a top plate 103 fixedly connected to the top of the four upright plates 102, an electric hydraulic cylinder 3 fixedly installed at the center of the top of the top of the top plate 103, the output end of the electric hydraulic cylinder 3 movably penetrating through the surface of the top plate 103 and a lifting plate 301 fixedly installed thereon, the lifting plate 301 being located on the inner side of the four upright plates 102 respectively, mounting brackets 302 fixedly connected to both sides of the bottom of the lifting plate 301, and auxiliary pressure limiting components 4 arranged on the inner side of the two mounting brackets 302.

[0023] Specifically: The auxiliary pressure limiting component 4, in conjunction with the electric hydraulic cylinder 3, can adjust the height of the pressure roller 405 when feeding hot-rolled stainless steel coils of different thicknesses. Furthermore, the pressure roller 405 can limit the feeding of hot-rolled stainless steel coils conveyed on the surface of the anti-slip drive roller 202, preventing the hot-rolled stainless steel coils from tilting excessively and causing unstable conveying.

[0024] In one embodiment, a number of legs 101 are fixedly connected to the bottom of both support frames 1, and a controller 5 is fixedly installed on one side of one of the support frames 1.

[0025] Specifically, such as Figure 1 As shown: Several support legs 101 are used to support two support frames 1, and the controller 5 is used to control the operation of the internal equipment of the device.

[0026] In one embodiment, the conveying assembly 2 includes a plurality of first drive shafts 201. One end of each of the plurality of first drive shafts 201 is mounted on one side of one of the support frames 1 via bearings, and the plurality of first drive shafts 201 are arranged equidistantly in a horizontal direction. Anti-slip drive rollers 202 are fixedly sleeved on the surface of each of the plurality of first drive shafts 201, and the plurality of anti-slip drive rollers 202 are located on the inner sides of the two support frames 1 respectively. The other end of each of the plurality of first drive shafts 201 is embedded through the surface of another support frame 1 via bearings and is fixedly sleeved with two first sprockets 203. A first chain 204 is provided at one end of each pair of adjacent first drive shafts 201. The plurality of first chains 204 are movably sleeved on the surface of the two adjacent first sprockets 203 in a staggered manner. A first motor 205 is fixedly installed at one end of the outer side of one of the support frames 1, and the output end of the first motor 205 movably passes through the surface of the support frame 1 and is fixedly connected to one end of one of the first drive shafts 201.

[0027] Specifically, such as Figure 1-3As shown: Through multiple staggered first chains 204, one of the first drive shafts 201 can be driven to rotate by the first motor 205, while the other multiple first drive shafts 201 are driven to rotate synchronously through the multiple first chains 204. The multiple first drive shafts 201 are horizontal and equidistant, so that the multiple anti-slip drive rollers 202 are also horizontal and equidistant. The gap between the multiple anti-slip drive rollers 202 is set to be small, so that the hot-rolled stainless steel coil placed on the surface of one end of the anti-slip drive roller 202 can be gradually conveyed forward as the anti-slip drive roller 202 rotates.

[0028] In one embodiment, guide guard plates 104 are fixedly installed on the opposite side surfaces of the two support frames 1 near the top. The two guide guard plates 104 are located above the multiple first drive shafts 201 and are correspondingly distributed on both sides of the multiple anti-slip drive rollers 202.

[0029] Specifically, such as Figure 3 As shown: Two guide guard plates 104 are respectively set between the two ends of the anti-slip drive roller 202 and the side walls of the two support frames 1, for guiding and protecting the conveying, so as to prevent the hot-rolled stainless steel coil from touching the support frame 1 during the conveying.

[0030] In one embodiment, the auxiliary pressure limiting component 4 includes a plurality of second drive shafts 401. One end of each of the plurality of second drive shafts 401 is mounted on one side of one of the mounting brackets 302 via bearings, and the plurality of second drive shafts 401 are arranged equidistantly in a horizontal direction. The other end of each of the plurality of second drive shafts 401 is mounted through the surface of another mounting bracket 302 via bearings and is fixedly fitted with two second sprockets 402. A second chain 403 is provided at one end of each pair of adjacent second drive shafts 401. The plurality of second chains 403 are movably fitted on the surface of the two adjacent second sprockets 402 in a staggered manner. Two pressure rollers 405 are fixedly fitted on the surface of each of the plurality of second drive shafts 401. The plurality of pressure rollers 405 are located on the inner sides of the two mounting brackets 302 respectively. A second motor 404 is fixedly mounted at one end of the outer side of one of the mounting brackets 302. The output end of the second motor 404 movably passes through the surface of the mounting bracket 302 and is fixedly connected to one end of one of the second drive shafts 401.

[0031] Specifically, such as Figure 1 , 4As shown in Figure -5: Through multiple staggered second chains 403, one of the second drive shafts 401 can be driven to rotate by the second motor 404, while the other multiple second drive shafts 401 are driven to rotate synchronously through the linkage of multiple second chains 403. The multiple second drive shafts 401 are horizontal and equidistantly arranged, so that the multiple pressure rollers 405 are also horizontally and equidistantly arranged. The gap between adjacent pressure rollers 405 is set to be small, which can press and limit the surface of the hot-rolled stainless steel coil conveyed forward and can assist in driving the raised surface of the hot-rolled stainless steel coil forward. Moreover, the two pressure rollers 405 on the surface of the same second drive shaft 401 are distributed on one side close to the two support frames 1, which can limit the two ends of the top of the hot-rolled stainless steel coil.

[0032] In one embodiment, two mounting brackets 302 are located directly above the two ends of the surfaces of the plurality of anti-slip drive rollers 202.

[0033] Specifically, such as Figure 1-2 As shown: the two mounting brackets 302 are located directly above the two ends of the surfaces of the multiple anti-slip drive rollers 202, so that the multiple pressure rollers 405 are located directly above the anti-slip drive rollers 202.

[0034] In one embodiment, T-shaped limiting posts 303 are fixedly connected to the four ends of the top of the lifting plate 301, and the surfaces of the four T-shaped limiting posts 303 are movably attached to the four ends of the top of the top plate 103.

[0035] Specifically, such as Figure 2 As shown: Four T-shaped limit posts 303 are used to guide and limit the lifting plate 301 to prevent the lifting plate 301 from deviating when it moves up and down. The four T-shaped limit posts 303 are distributed at the four ends of the top of the lifting plate 301, which can also help to maintain the balance of the lifting plate 301.

[0036] Working principle:

[0037] This device is used for feeding hot-rolled stainless steel coils of the same width. The pressure rollers 405 on both sides can be correspondingly limited on both sides of the top of the hot-rolled stainless steel coil. When using this hot-rolled stainless steel coil feeding device to feed the hot-rolled stainless steel coil unwound by the uncoiler to the bottom of the processing equipment, the device can be placed on one side of the uncoiler and the other end can be connected to one side of the processing equipment. The unwound hot-rolled stainless steel coil extends into the feeding device from one side and is fed.

[0038] When feeding hot-rolled stainless steel coils, the distance between the pressure roller 405 and the anti-slip drive roller 202 can be adjusted in advance according to the thickness of the hot-rolled stainless steel coil. The electric hydraulic cylinder 3 is operated by the controller 5. When the output end of the electric hydraulic cylinder 3 extends downward, it will drive the lifting plate 301 to move down. The downward movement of the lifting plate 301 will simultaneously drive the entire conveying assembly 2 to move down, thereby adjusting the distance between the pressure roller 405 and the anti-slip drive roller 202. According to the thickness of the hot-rolled stainless steel coil, the distance between the pressure roller 405 and the anti-slip drive roller 202 can be adjusted to be slightly greater than the thickness of the hot-rolled stainless steel coil.

[0039] When feeding the hot-rolled stainless steel coil, one end of it is placed on the surface of the anti-slip drive roller 202 on the inner side of one end of the two support frames 1. At this time, the hot-rolled stainless steel coil is located between the pressure roller 405 and the anti-slip drive roller 202 and is limited by both. Then, the controller 5 operates the first motor 205 and the second motor 404. The operation of the first motor 205 will drive the first drive shaft 201 connected to it to rotate. The rotation of the first drive shaft 201 will drive the anti-slip drive roller 202 to rotate. At the same time, the rotation of the first drive shaft 201 will drive the first chain 20 through the first sprocket 203 at one end. 4. Rotation: Since multiple first chains 204 are staggered and mesh with the first sprocket 203 at one end of the adjacent first drive shaft 201, when one end of the first drive shaft 201 rotates, it will synchronously drive the other multiple first drive shafts 201 and the anti-slip drive roller 202 to rotate synchronously, so that the hot-rolled stainless steel coil placed on its surface moves. When the second motor 404 rotates and drives the second drive shaft 401 to rotate, it works on the same principle as the above-mentioned conveying component 2. The second chain 403, which is staggered, is driven by the second sprocket 402 to run and rotate, causing multiple pressure rollers 405 to rotate.

[0040] Since the distance between the pressure roller 405 and the anti-slip drive roller 202 is only slightly greater than the thickness of the hot-rolled stainless steel coil, and the pressure roller 405 and the anti-slip drive roller 202 rotate in opposite directions, the hot-rolled stainless steel coil extending between the pressure roller 405 and the anti-slip drive roller 202 is limited by the two, preventing it from tilting excessively. When the tilted part touches the pressure roller 405 rotating in the opposite direction, the pressure roller 405 will also assist in driving the hot-rolled stainless steel coil to move forward. The anti-slip drive roller 202 and the pressure roller 405 cooperate to convey the inner hot-rolled stainless steel coil forward, making the feeding more stable.

[0041] With the above-mentioned structure, the auxiliary pressure limiting component 4 and the electric hydraulic cylinder 3 are configured to adjust the height of the pressure roller 405 when feeding hot-rolled stainless steel coils of different thicknesses. The pressure roller 405 can limit the feeding of hot-rolled stainless steel coils conveyed on the surface of the anti-slip drive roller 202, and prevent the hot-rolled stainless steel coils from tilting too much and causing unstable conveying.

[0042] The control circuit of this utility model controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, this utility model does not involve improvements to the controller and power supply circuit connection. Therefore, this utility model will not explain the control method and circuit connection in detail.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
