Description

Technical Field

[0001] The present application belongs to the technical field of strip coiling, and specifically relates to a coiling device. Background Art

[0002] Hot rolled strip steel is divided into hot rolled narrow strip steel and hot rolled strip steel according to its size. Hot rolled narrow strip steel is usually cooled by guide rollers, flipped 90° and then coiled into coils.

[0003] In the prior art, guide rollers are equipped with limit rings at both ends to limit the width of the hot-rolled narrow strip and prevent the strip from deviating. However, due to the different width specifications of the hot-rolled narrow strip, the axial length requirements of the guide rollers also vary. If the width specification of the produced strip changes, it is necessary to replace the guide rollers with those that match the target width specification to limit the replacement hot-rolled narrow strip. However, this method requires removing the guide rollers and reinstalling the new guide rollers, which is very cumbersome and affects production efficiency. Summary of the Invention

[0004] In order to solve the current technical problems of cumbersome disassembly and low production efficiency caused by the need to replace conveyor rollers for hot-rolled narrow strip steels with different production width specifications, the present application provides a winding device.

[0005] In a first aspect of the present application, a winding device is provided, comprising:

[0006] Coiler assembly, used for coiling strip steel;

[0007] A guide assembly is used to guide the strip steel into the coiler and is located on the material side of the coiling assembly. The guide assembly includes two guide rollers arranged with a gap along the height direction. The guide roller includes a roller sleeve, a core shaft and a limit ring. There are at least two roller sleeves. The core shaft is provided with multiple mounting positions arranged in sequence along the axial direction. The number of the mounting positions is greater than the number of the roller sleeves. At least two of the roller sleeves are arranged in sequence along the axial direction of the core shaft. The roller sleeves can be selectively installed in any of the mounting positions. There are two limit rings. The two limit rings are connected to both sides of the at least two roller sleeves. The limit rings extend radially from the roller sleeves.

[0008] In some embodiments, the core shaft is provided with a plurality of axial limit holes arranged in sequence along the axial direction, and the space between two of the axial limit holes forms the mounting position. The guide roller also includes axial limit pins twice the number of the roller sleeves. One end of the axial limit pin extends into the axial limit hole, and the other end extends out of the core shaft and presses against the corresponding roller sleeve. Each roller sleeve is provided with axial limit pins on both sides along the axial direction, and the two limit pins located on the outermost sides are respectively pressed against the two limit rings.

[0009] In some embodiments, the axial limiting hole passes through the radial direction of the core shaft, the axial limiting pin is inserted into the axial limiting hole, and both ends extend out of the axial limiting hole and press against the corresponding roller sleeve.

[0010] In some embodiments, a connecting ring is provided on one side of the limiting ring along the axial direction, the roller sleeve is provided with a connecting groove, and the connecting ring is located in the connecting groove.

[0011] In some embodiments, the guide assembly further includes a first driving member, which is transmission-connected to the guide roller located below.

[0012] In some embodiments, the guide assembly is provided in multiple groups, and the multiple groups of guide assemblies are arranged in sequence along the running direction of the strip.

[0013] In some embodiments, the winding assembly includes a base, a second driving member, a winding column and a support plate. The shell of the second driving member is provided on the base. The second driving member is transmission-connected to the winding column. The support plate is provided with a through hole for the output shaft of the second driving member to pass through.

[0014] In some embodiments, the winding rod is provided with a slot extending axially therethrough.

[0015] In some embodiments, a conveying assembly is further included between the guide assembly and the coiling assembly, and the conveying assembly includes a plurality of conveying rollers sequentially arranged along the running direction of the strip steel.

[0016] In some embodiments, a cooling assembly is further included, wherein the cooling assembly includes a plurality of nozzles sequentially arranged along the running direction of the strip steel, and the nozzles are provided with nozzles for spraying water toward the strip steel.

[0017] According to an embodiment of the present application, a winding device is provided, comprising a winding assembly and a guide assembly, wherein the winding assembly is used to wind strip steel. The guide assembly is used to guide the strip steel into the coiler and is located on the incoming material side of the winding assembly. The guide assembly comprises two guide rollers spaced apart in a height direction. The guide rollers comprise roller sleeves, a core shaft, and a limiting ring. At least two roller sleeves are provided. The core shaft is provided with multiple mounting positions sequentially arranged along the axial direction. The number of mounting positions is greater than the number of roller sleeves. At least two roller sleeves are sequentially arranged along the axial direction of the core shaft. The roller sleeves can be selectively installed in any mounting position. Two limiting rings are provided. The two limiting rings are connected to both sides of the at least two roller sleeves and extend radially from the roller sleeves.

[0018] The two guide rollers are spaced apart in height, forming a steel channel for the strip to pass through. Limit rings are installed at both ends of the upper and lower guide rollers. As the strip passes through the channel, it is restricted by the rings extending beyond the roller sleeves, preventing it from straying. Because the mandrel has multiple axial mounting positions, and the roller sleeves can be installed in any position, the position of the two outermost roller sleeves is adjustable, allowing for the axial spacing between the two limit rings to be adjusted, thus accommodating strip widths of varying specifications.

[0019] Since the distance between the two limiting rings can be adjusted by only adjusting the axial installation position of the roller sleeve, there is no need to remove the old guide roller and replace it with a guide roller of new specifications, thereby improving production efficiency.

[0030] In order to enable those skilled in the art to understand the present application more clearly, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of this application.

[0031] The first embodiment of the present application provides a winding device that can realize the winding of strip steel of multiple width specifications without disassembling the guide roller, and has high production efficiency.

[0032] See also Figures 1 to 3 The winding device provided in the embodiment of the present application includes a guide assembly 100 and a winding assembly arranged in sequence.

[0033] See also Figures 3 to 5 The guide assembly 100 is used to guide the strip 400 into the coiler to prevent the strip 400 from deviating in the width direction. The guide assembly 100 is located on the incoming material side of the coiling assembly 300. The guide assembly 100 includes two guide rollers 110 arranged in sequence along the height direction. The guide rollers 110 include a roller sleeve 111, a core shaft 112, and a limiting ring 113. There are at least two roller sleeves 111. The core shaft 112 has multiple mounting positions arranged in sequence along the axial direction. The number of mounting positions is greater than the number of roller sleeves 111. At least two roller sleeves 111 are arranged in sequence along the axial direction of the core shaft 112. The roller sleeves 111 can be selectively installed in any mounting position. There are two limiting rings 113. The two limiting rings 113 are connected to both sides of the at least two roller sleeves 111 and extend radially from the roller sleeves 111.

[0034] The two guide rollers 110 are spaced apart in height, forming a steel passageway for the steel strip 400. Limit rings 113 are installed at both ends of the upper and lower guide rollers 110. As the steel strip 400 passes through the steel passageway, it is restricted by the portion of the limit rings 113 that extends beyond the roller sleeves 111, preventing the strip 400 from straying. Because the mandrel 112 has multiple axial mounting positions, and the roller sleeves 111 can be installed in any of these positions, the position of the two outermost roller sleeves 111 is adjustable, allowing for adjustable axial spacing between the two limit rings 113, thus accommodating strip 400 of varying widths.

[0035] Since the distance between the two limiting rings 113 can be adjusted by only adjusting the axial installation position of the roller sleeve 111, there is no need to remove the old guide roller 110 and replace it with a new guide roller 110, thereby improving production efficiency.

[0036] In some embodiments, three roller sleeves 111 are provided, and the three roller sleeves 111 are respectively a first roller sleeve 111, a second roller sleeve 111 and a third roller sleeve 111 along the axial direction of the mandrel 112. The mandrel 112 is provided with five mounting positions, and the five mounting positions are sequentially arranged along the axial direction and are respectively a first mounting position, a second mounting position, a third mounting position, a fourth mounting position and a fifth mounting position. The second roller sleeve 111 is located at the third mounting position of the mandrel 112, the first roller sleeve 111 is selectively mounted at the first mounting position or the second mounting position, and the third roller sleeve 111 is selectively mounted at the fourth mounting position or the fifth mounting position. Please refer to Figure 4 When the first roller sleeve 111 is mounted at the second mounting position, the second roller sleeve 111 is mounted at the third mounting position, and the third roller sleeve 111 is mounted at the fourth mounting position, the guide roller 110 is suitable for a first width of the strip steel 400. Please refer to Figure 5 When the first roller sleeve 111 is mounted at the first mounting position, the second roller sleeve 111 is mounted at the third mounting position, and the third roller sleeve 111 is mounted at the fifth mounting position, the guide roller 110 is suitable for a second width of the strip steel 400, and the second width is greater than the first width. Of course, the above is only an example, and in other embodiments, the roller sleeves 111 can also be provided with two, which are respectively a first roller sleeve 111 and a second roller sleeve 111, and the mounting positions are provided with four, which are respectively a first mounting position, a second mounting position, a third mounting position and a fourth mounting position sequentially arranged along the axial direction. One of the roller sleeves 111 is mounted at the first mounting position or the second mounting position, and the other roller sleeve 111 is mounted at the third mounting position or the fourth mounting position.

[0037] In some embodiments, the mandrel 112 is provided with a plurality of axial limiting holes 112a sequentially arranged along the axial direction, and the space between two limiting holes forms a mounting position. The guide roller 110 further includes axial limiting pins 114 which are twice the number of the roller sleeves 111. One end of the axial limiting pin 114 extends into the axial limiting hole 112a, and the other end extends out of the mandrel 112 and abuts against the corresponding roller sleeve 111. Each roller sleeve 111 is provided with an axial limiting pin 114 on both sides along the axial direction, and the two limiting pins located at the outermost sides abut against the two limiting rings 113 respectively. It should be explained that the space between the two limiting holes can be adjacent two limiting holes or non-adjacent two limiting holes, which can be selected according to the actual situation, and the present application does not make any limitation.

[0038] In some embodiments, the axial limiting hole 112a penetrates the radial direction of the mandrel 112, and the axial limiting pin 114 is arranged in the corresponding axial limiting hole 112a and extends out of the axial limiting hole 112a at both ends to abut against the corresponding roller sleeve 111, so as to improve the installation stability of the roller sleeve 111.

[0039] In some embodiments, a connecting ring is provided on one axial side of the limiting ring 113, a connecting groove is provided on the roller sleeve 111, and the connecting ring is located within the connecting groove, thereby improving the stability of the connection between the limiting ring 113 and the roller sleeve 111. In other embodiments, a connecting groove is provided on the axial end surface of the limiting ring 113, and a connecting ring is provided on the end surface of the roller sleeve 111, and the connecting ring is located within the connecting groove, thereby also achieving connection between the limiting ring 113 and the roller sleeve 111. In specific implementations, all roller sleeves 111 have the same structure, that is, roller sleeves 111 not connected to the limiting ring 113 also have a connecting groove / connecting ring. This ensures that all roller sleeves 111 have the same structure, requiring only one spare part, rather than two.

[0040] In some embodiments, the guiding assembly 100 further includes a first driving member 120, such as a motor, which is connected to the guide roller 110 located below. That is, the guide roller 110 below is an active roller, and the guide roller 110 above is a driven roller. When the strip steel 400 passes through the steel channel, it will contact the guide roller 110 below, and the strip steel 400 will be driven forward by friction.

[0041] In some embodiments, multiple sets of guide assemblies 100 are provided, and the multiple sets of guide assemblies 100 are sequentially arranged along the running direction of the steel strip 400 to improve the stability of the steel strip 400 passing through the steel passage. In other embodiments, only one set of guide assemblies 100 can be provided to still achieve the guidance of the steel strip 400.

[0042] In some embodiments, see Figure 1 The coiling device further includes a cooling assembly 200 located between the guide assembly 100 and the coiling assembly 300 to cool the hot-rolled strip 400. Figure 1 as well as Figure 2 The cooling assembly 200 includes a cooling roller 230, a nozzle 220, a spray pipe 210, and a water tank 250. Multiple cooling rollers 230 are provided and arranged sequentially along the running direction of the steel strip 400 to support the running of the steel strip 400. Multiple nozzles 220 are provided and mounted on the spray pipe 210. The spray pipe 210 is located above the steel strip 400 and sprays cooling water onto the steel strip 400 through the nozzles 220 to cool the steel strip 400. The water tank 250 is located below the cooling roller 230 and is used to store cooling water. The cooling tank is connected to the spray pipe 210 via a water pump, thereby spraying cooling water through the nozzles 220.

[0043] In some embodiments, the cooling assembly 200 also includes a water collecting block 240, which is located below the cooling roller 230. The water collecting block 240 is provided with a water collecting hole 241, and the water tank 250 is connected to the water collecting hole 241. After the cooling water contacts the strip steel 400 to dissipate heat, it flows to the water collecting hole 241 of the water collecting block 240 under the action of gravity, and then enters the water tank 250.

[0044] The coiling assembly 300 serves as a coiling structure for the strip steel 400. In some embodiments, refer to Figure 1 as well as Figure 2 The coiling assembly 300 includes a base 310, a second drive member 320, a coiling column 340, and a support plate 330. The second drive member 320 may be a motor, the housing of which is disposed on the base 310. The second drive member 320 is in driving connection with the coiling column 340. The support plate has a through hole through which the output shaft of the second drive member 320 passes. The second drive member 320 rotates, driving the coiling column 340 to rotate, thereby coiling the steel strip 400 onto the coiling column 340. The support plate may be configured to contact the end face of the steel coil and rotate along with the output end of the second drive member 320 to provide support for the steel strip 400. In a specific implementation, the coiling column 340 may extend vertically or horizontally, and this application does not impose any limitations thereto.

[0045] In some embodiments, see Figure 1 The coiling rod 340 is provided with a slot 341 extending axially therethrough, so that the head of the strip 400 can be inserted into the slot 341 and clamped before being coiled. In other embodiments, the head of the strip 400 can be fixed with a tool, and after a few turns, the strip head is locked and then coiled.

[0046] The coiling device provided in the present application solves the technical problem of low production efficiency caused by the need to disassemble the entire guide roller 110 in order to produce strip steel 400 of different width specifications in traditional hot-rolled plate coiling devices.
