Abstract
Description
Technical Field
[0001] This utility model relates to the field of hot-rolled strip production technology, and in particular to a novel auxiliary device for preventing loosening of hot-rolled strip coiling machines. Background Technology
[0002] A coiler is an auxiliary device in a steel rolling mill that coils hot-rolled or cold-rolled steel into coils. On hot strip mills, cold strip mills, and wire rod mills, it is located after the finishing mill stand. On single-stand reversible cold strip mills, it is installed before or after the mill. In addition, it is also installed in various finishing units such as continuous pickling units, slitting, annealing, and coating units. When coiling hot-rolled strip, an anti-loosening device is required to make the hot-rolled strip coil more compact. However, the anti-loosening device of traditional hot-rolled strip coilers is not convenient to adjust according to the thickness of the coil and is not convenient to move.
[0003] Therefore, those skilled in the art have provided a novel auxiliary device for preventing loosening of hot-rolled strip coilers to solve the problems mentioned in the background art. Utility Model Content
[0004] To address the problems of traditional hot-rolled strip coiler anti-loosening devices being inconvenient to adjust according to the coil thickness and difficult to handle and move, this utility model provides a novel auxiliary device for hot-rolled strip coiler anti-loosening.
[0005] This utility model provides a novel auxiliary device for preventing loosening of coils in a hot-rolled strip coiling machine, which adopts the following technical solution:
[0006] A novel auxiliary device for preventing loosening of hot-rolled strip coiling machines includes a worktable. A coiling mechanism is installed on one side of the top of the worktable. The coiling mechanism includes a support plate. A transmission rod is rotatably connected to the top of one side of the support plate via a bearing. A positioning rod is fixedly installed at one end of the transmission rod. A coiling roller body is sleeved on the surface of the positioning rod. A positioning nut is threaded to one end of the positioning rod. The surface of the coiling roller body is coiled with hot-rolled strip body. An anti-loosening mechanism is installed on the top of the worktable. The anti-loosening mechanism includes a first electric push rod. A support frame is fixedly installed at the output end of the first electric push rod. A support roller is rotatably connected to the inner cavity of the support frame. A moving mechanism is installed at the bottom of the worktable.
[0007] By setting up a coiling mechanism, the hot-rolled strip body can be coiled. Unscrewing the positioning nut makes it easy to remove the coiling roller body from the positioning rod. By setting up an anti-loosening mechanism, the height of the support roller can be adjusted by controlling the extension and retraction of the first electric push rod, which can be adjusted according to the thickness of the coiling, so that the support roller is always in contact with the hot-rolled strip body, thereby preventing loosening. By setting up a moving mechanism, the height of the caster wheel can be adjusted by controlling the extension and retraction of the second electric push rod, thereby facilitating the movement of the device.
[0008] The winding mechanism also includes a stepper motor and a driven gear. The stepper motor is fixedly connected to the support plate, and the driven gear is fixedly connected to the transmission rod. The driven gear meshes with the drive gear.
[0009] By turning on the stepper motor, the drive gear can be rotated, which in turn drives the driven gear to rotate, which in turn drives the transmission rod to rotate, which in turn drives the positioning rod to rotate, and the positioning rod drives the roll body to rotate, thus curling the hot-rolled strip body.
[0010] The curling mechanism also includes a protective cover, which is fixedly connected to the support plate.
[0011] The protective cover serves to prevent dust from entering and affecting the meshing of the drive gear and driven gear.
[0012] There are two first electric push rods, and the first electric push rods are fixedly connected to the worktable.
[0013] Two first electric push rods make the support rollers more stable.
[0014] There are four sets of moving mechanisms, which are distributed around the bottom of the worktable.
[0015] Four sets of moving mechanisms make the device more stable.
[0016] The moving mechanism includes a support leg, which is fixedly connected to the worktable. A second electric push rod is fixedly installed on the top of the inner cavity of the support leg. A cross plate is fixedly installed on the output end of the second electric push rod, and a caster wheel is rotatably connected to the bottom of the cross plate.
[0017] Using the above technical solution, by controlling the extension of the second electric push rod, the horizontal plate can be pushed downward, and the horizontal plate drives the caster to move downward. The caster contacts the ground, thus facilitating the movement of the device. Controlling the retraction of the second electric push rod can retract the caster, and the support leg contacts the ground, thus stabilizing the device.
[0018] Guide sliders are fixedly installed on both the left and right sides of the horizontal plate, and guide grooves that cooperate with the guide sliders are opened in the inner cavity of the support leg.
[0019] By adopting the above technical solution, the guide slider and the guide groove are used together to guide the horizontal plate and make the horizontal plate move stably.
[0020] Beneficial effects:
[0021] 1. This utility model, by setting a coiling mechanism, can coil the hot-rolled strip body. By unscrewing the positioning nut, the coiling roller body can be easily removed from the positioning rod. By setting an anti-loosening mechanism, the height of the support roller can be adjusted by controlling the extension and retraction of the first electric push rod, which can be adjusted according to the thickness of the coiling, so that the support roller and the hot-rolled strip body are always in close contact, thereby preventing loosening. By setting a moving mechanism, the height of the caster wheel can be adjusted by controlling the extension and retraction of the second electric push rod, thereby facilitating the movement of the device.
[0022] 2. This utility model utilizes a stepper motor to drive a drive gear, which in turn drives a driven gear, which in turn drives a transmission rod, which in turn drives a positioning rod, which in turn drives the roll body to rotate. This allows for the coiling of the hot-rolled strip. The protective cover prevents dust from entering and affecting the meshing of the drive and driven gears. Two first electric push rods stabilize the support rollers, and four sets of moving mechanisms further enhance stability. By extending the second electric push rod, the horizontal plate can be pushed downwards, causing the casters to move downwards and contact the ground, facilitating device movement. Retracting the second electric push rod retracts the casters, bringing the support legs into contact with the ground and ensuring device stability. The guide slider and guide groove work together to guide the horizontal plate, ensuring stability during movement. Attached Figure Description

[0029] The present invention will be further described in detail below through specific embodiments:
[0030] Example 1
[0031] Please refer to Figure 1 and Figure 3 A novel auxiliary device for preventing loosening of hot-rolled strip coiling machines includes a worktable 1. A coiling mechanism 2 is provided on one side of the top of the worktable 1. The coiling mechanism 2 includes a support plate 201. A transmission rod 204 is rotatably connected to the top of one side of the support plate 201 via a bearing. A positioning rod 206 is fixedly installed at one end of the transmission rod 204. A coiling roller body 207 is sleeved on the surface of the positioning rod 206. A positioning screw sleeve 208 is threaded to one end of the positioning rod 206. The coiling mechanism 2 also includes a stepper motor 202 and a driven gear 205. The stepper motor 202 is fixedly connected to the support plate 201. The driven gear 205 is fixedly connected to the transmission rod 204 and meshes with a drive gear 203. The coiling mechanism 2 also includes a protective cover 209, which is fixedly connected to the support plate 201. A hot-rolled strip body 3 is coiled on the surface of the coiling roller body 207.
[0032] In this embodiment: by setting up a winding mechanism 2, turning on the stepper motor 202 can drive the drive gear 203 to rotate, the drive gear 203 drives the driven gear 205 to rotate, the driven gear 205 drives the transmission rod 204 to rotate, the transmission rod 204 drives the positioning rod 206 to rotate, and the positioning rod 206 drives the winding roller body 207 to rotate, which can wind the hot-rolled strip body 3. Unscrewing the positioning nut 208 makes it easy to remove the winding roller body 207 from the positioning rod 206. The protective cover 209 plays a protective role, preventing dust from entering and affecting the meshing of the drive gear 203 and the driven gear 205.
[0033] Example 2
[0034] Reference Figure 1 , Figure 2 and Figure 4The top of the workbench 1 is provided with an anti-loosening mechanism 4, which includes a first electric push rod 401. The output end of the first electric push rod 401 is fixedly installed with a support frame 402. The inner cavity of the support frame 402 is rotatably connected with a support roller 403. There are two first electric push rods 401, which are fixedly connected to the workbench 1. The bottom of the workbench 1 is provided with a moving mechanism 5, which consists of four sets distributed around the bottom of the workbench 1. The moving mechanism 5 includes a support leg 501, which is fixedly connected to the workbench 1. The top of the inner cavity of the support leg 501 is fixedly installed with a second electric push rod 502. The output end of the second electric push rod 502 is fixedly installed with a horizontal plate 503. The bottom of the horizontal plate 503 is rotatably connected with a caster wheel 504. Guide sliders 505 are fixedly installed on both the left and right sides of the horizontal plate 503. The inner cavity of the support leg 501 is provided with a guide groove 506 that works with the guide slider 505.
[0035] In this embodiment: by setting an anti-loosening mechanism 4, the height of the support roller 403 can be adjusted by controlling the extension and retraction of the first electric push rod 401, which is convenient to adjust according to the thickness of the coil, so that the support roller 403 is always in contact with the hot-rolled strip body 3, thereby avoiding loosening. The two first electric push rods 401 can make the support roller 403 more stable. By setting a moving mechanism 5, four sets of moving mechanisms 5 can make the device more stable. By controlling the extension of the second electric push rod 502, the horizontal plate 503 can be pushed to move downward. The horizontal plate 503 drives the universal wheel 504 to move downward. The universal wheel 504 contacts the ground, thereby facilitating the movement of the device. Controlling the retraction of the second electric push rod 502 can retract the universal wheel 504, and the support leg 501 contacts the ground, thereby making the device stable. The guide slider 505 and the guide groove 506 work together to guide the horizontal plate 503, so that the horizontal plate 503 moves stably.
[0036] The implementation principle of this utility model is as follows: In use, extending the second electric push rod 502 pushes the horizontal plate 503 downwards, causing the universal wheel 504 to move downwards and contact the ground, thus facilitating device movement. Retracting the second electric push rod 502 retracts the universal wheel 504, causing the support leg 501 to contact the ground, thereby stabilizing the device. Turning on the stepper motor 202 drives the drive gear 203 to rotate, which in turn drives the driven gear 205 to rotate. 205 drives the transmission rod 204 to rotate, the transmission rod 204 drives the positioning rod 206 to rotate, and the positioning rod 206 drives the roll body 207 to rotate, which can roll the hot-rolled strip body 3. The first electric push rod 401 is controlled to extend and push the support frame 402 to move upward. The support frame 402 drives the support roller 403 to move upward, so that the support roller 403 is in contact with the hot-rolled strip body 3 to avoid loosening. During the rolling process, the first electric push rod 401 is controlled to retract, and the height of the support roller 403 can be adjusted according to the rolling thickness.
