Description

Technical Field

[0001] This utility model relates to the field of steel rolling processing technology, specifically to a cold-rolled steel sheet coiling device. Background Technology

[0002] Cold-rolled steel sheet coiling involves continuously and uniformly winding cold-rolled steel sheets into coils using a coiling machine, which facilitates storage, transportation, and subsequent processing.

[0003] Chinese Patent Publication No. CN219620444U discloses a cold-rolled steel sheet coiling device, including a base plate, a frame at the top of the base plate, an electrical control box at the front end of one side of the top of the base plate, a control panel near the top of the electrical control box, and a drive motor at the top of the electrical control box. By providing clamping structures on both sides at the middle of the top of the frame, the coiling shaft continuously applies pressure to the steel sheet through clamping rollers as it rotates to coil the steel sheet, ensuring the steel sheet is stably coiled on the coiling shaft. As the thickness of the coiled steel sheet increases, the compression spring is continuously compressed, causing the clamping rollers to move upwards while simultaneously applying downward pressure to maintain the clamping effect. At the same time, a movable top rod rises inside a stabilizing sleeve. The stabilizing sleeve and the movable top rod ensure the stability of the compression spring, thereby ensuring the clamping rollers are fixed in position and achieve the clamping effect, thus ensuring the effective coiling of the steel sheet.

[0004] In the aforementioned prior art, the guide roller can be used to limit and guide the coiled steel plate to improve the stability of the coiling process. However, the position of the coiled steel plate changes with the thickness of the coil, and the guide roller is not easy to adapt to the change in the thickness of the coil. As a result, when the thickness of the coil changes, the contact angle between the subsequently coiled steel plate and the guide roller will change, the contact pressure between the guide roller and the steel plate will be uneven, and the local pressure will be too high, which can easily scratch the surface of the steel plate or cause lateral displacement. Utility Model Content

[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cold-rolled steel sheet coiling device to solve the problem that the guide rollers of the cold-rolled steel sheet coiling device mentioned in the background art are not easy to adapt to changes in the thickness of the steel sheet coil, resulting in uneven contact pressure between the guide rollers and the steel sheet, excessive local pressure, and easy scratching of the steel sheet surface or lateral displacement.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A cold-rolled steel sheet coiling device, comprising:

[0008] A steel plate coiling machine, wherein the steel plate coiling machine is equipped with a coiling roller, is characterized in that it further includes:

[0009] A guide structure, arranged on the steel plate coiling machine, is used to guide the coiled steel plate;

[0010] An alarm structure is arranged on the steel plate coiling machine and used in conjunction with the guide structure to trigger an alarm when the steel plate of the corresponding thickness is coiled.

[0011] The guard structure is arranged on the steel plate coiling machine and is used to block the steel plate coil on both sides.

[0012] Preferably, the guide structure includes:

[0013] The L-shaped frame is arranged on one side of the steel plate coiling machine;

[0014] Several guide rods are slidably installed inside the L-shaped frame;

[0015] The movable frame is positioned at one end of the guide rod;

[0016] Two guide rollers are rotatably mounted on the movable frame, and the two guide rollers are in contact with the two sides of the steel plate respectively;

[0017] An extrusion assembly, arranged on a movable frame, is used to press and tighten the coiled steel sheet.

[0018] Preferably, the extrusion assembly includes:

[0019] Both extrusion rollers are rotatably mounted on a movable frame;

[0020] Several springs are movably mounted on corresponding guide rods, with the two ends of the springs respectively arranged between the L-shaped frame and the movable frame.

[0021] Preferably, the alarm structure includes:

[0022] The limiting slide is slidably installed inside the L-shaped frame;

[0023] The control switch is located below the limit carriage;

[0024] An audible and visual alarm is installed above the L-shaped frame. The audible and visual alarm is electrically connected to a control module, which is electrically connected to the steel plate coiling machine.

[0025] An adjustment component, arranged on the limiting slide, is used to adjust the height of the limiting slide.

[0026] Preferably, the adjustment component includes:

[0027] The adjusting screw is threaded inside the limiting slide.

[0028] A guide slide hole is formed inside the L-shaped frame, and the limiting slide is slidably installed in the guide slide hole to guide the limiting slide to move in the vertical direction.

[0029] Preferably, the adjustment assembly further includes a limiting turntable, which is rotatably installed inside the L-shaped frame and arranged at one end of the adjusting screw to prevent the adjusting screw from coming loose from the L-shaped frame.

[0030] Preferably, the protective structure includes:

[0031] Two movable carriages are symmetrically slidably installed inside the L-shaped frame;

[0032] Two side rollers are rotatably mounted on two movable carriages.

[0033] Preferably, the protective structure further includes:

[0036] The beneficial effects of this utility model are as follows:

[0037] In this invention, when coiling a steel plate, the extrusion roller can press against the steel plate under the elastic force of a spring, preventing the coiled steel plate from sliding or misaligning. Two guide rollers work together to limit and guide the coiled steel plate, thereby improving the stability during coiling. Furthermore, the height of both the extrusion roller and the guide rollers can be adjusted according to changes in the thickness of the steel plate coil. While coiling the steel plate to the corresponding thickness, the movable frame is pressed and triggers the control switch. The control switch then uses the control module to activate the audible and visual alarm, simultaneously stopping the steel plate coiling machine to remind workers to replace the steel plate coil in a timely manner.

[0038] This invention allows for the adjustment of the height of the limit slide and the control switch by rotating the adjusting screw. This ensures that the steel plate needs to be wound to a thickness corresponding to the height of the control switch before the control switch can be triggered to sound an alarm, thus allowing for adjustment based on the required thickness of the steel plate to be wound.

[0039] This invention features two sets of side guard rollers that can be used to protect the ends of the steel plate coil, preventing the steel plate from tilting or shifting to the sides during the coiling process. The distance between the two side guard rollers can be adjusted by rotating the bidirectional screw to accommodate steel plates of different widths. Attached Figure Description

[0049] 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.

[0050] Example 1:

[0051] like Figures 1 to 6 As shown, this utility model provides a cold-rolled steel plate coiling device, including: a steel plate coiler 1, a coiling roller 101 provided on the steel plate coiler 1, and a guide structure arranged on the steel plate coiler 1 for guiding the coiled steel plate.

[0052] The guiding structure includes an L-shaped frame 2 arranged on one side of the steel plate coiler 1, several guide rods 201 slidably installed inside the L-shaped frame 2, a movable frame 202 arranged at one end of the guide rods 201, two guide rollers 203 rotatably installed on the movable frame 202, the two guide rollers 203 respectively contacting the two sides of the steel plate, and an extrusion assembly arranged on the movable frame 202 for pressing the coiled steel plate. The steel plate coiler 1 drives the coiling roller 101 to rotate to coil the steel plate. The steel plate can pass through the two guide rollers 203, and the two guide rollers 203 are used to limit and guide the steel plate.

[0053] Specifically, the extrusion assembly includes two extrusion rollers 204 rotatably mounted on the movable frame 202, and several springs 205 movably sleeved on the corresponding guide rods 201. The two ends of the springs 205 are respectively arranged between the L-shaped frame 2 and the movable frame 202. The extrusion rollers 204 will press against the coiled steel plate under the elastic force of the springs 205 to prevent the coiled steel plate from sliding and misaligning. The extrusion rollers 204 will move upward due to the change in the thickness of the steel plate, so that the extrusion rollers 204 can drive the movable frame 202 to move upward. The movable frame 202 can compress the springs 205 and drive the guide rollers 203 and guide rods 201 to rise.

[0054] Example 2:

[0055] Based on Example 1, in order to promptly remind the staff to replace the steel plate after winding the corresponding thickness steel plate, an alarm structure is arranged on the steel plate winding machine 1 to trigger an alarm when winding the corresponding thickness steel plate.

[0056] The alarm structure includes a limiting slide 3 slidably installed inside the L-shaped frame 2, a control switch 301 arranged below the limiting slide 3, and an audible and visual alarm 302 arranged above the L-shaped frame 2. The audible and visual alarm 302 and the control switch 301 are electrically connected to a control module, which is electrically connected to the steel plate coiling machine 1. An adjustment component is arranged on the limiting slide 3 to adjust the height of the limiting slide 3. When the coiled steel plate reaches the corresponding thickness, the continuously rising movable frame 202 will squeeze and trigger the control switch 301. The control module drives the audible and visual alarm 302 to sound an alarm, control the steel plate coiling machine 1 to stop operating, and remind the staff to replace the coiled steel plate in time.

[0057] Specifically, the adjustment assembly includes an adjusting screw 303 threaded inside the limiting slide 3, and a guide slide hole 304 opened inside the L-shaped frame 2 to guide the limiting slide 3 to move vertically. The limiting slide 3 is slidably installed in the guide slide hole 304. Rotating the adjusting screw 303 can cause it to move up and down within the guide slide hole 304 through its threaded engagement with the limiting slide 3, thereby adjusting the height of the control switch 301. The guide slide hole 304 can guide the movement of the limiting slide 3.

[0058] Specifically, the adjustment assembly also includes a limiting turntable 305 rotatably installed inside the L-shaped frame 2 to prevent the adjusting screw 303 from coming loose from the L-shaped frame 2. The limiting turntable 305 is arranged at one end of the adjusting screw 303. Rotating the adjusting screw 303 can cause it to drive the limiting turntable 305 to rotate inside the L-shaped frame 2. The setting of the limiting turntable 305 can prevent the adjusting screw 303 from falling off.

[0059] Example 3:

[0060] Based on Example 1, in order to prevent the steel plate from shifting to both sides during winding, a protective structure for blocking the sides of the steel plate coil is arranged on the steel plate winding machine 1.

[0061] The protective structure includes two movable slides 4 symmetrically slidably installed inside the L-shaped frame 2, and two side rollers 401 rotatably installed on the two movable slides 4 respectively. The side rollers 401 on both sides can protect the sides of the coiled steel plate and can rotate with the rotation of the steel plate to prevent the steel plate from tilting or shifting to the sides when it is coiled.

[0062] The guard structure also includes a bidirectional lead screw 402 rotatably installed inside the L-shaped frame 2. The bidirectional lead screw 402 is threaded inside the two movable slides 4. Two horizontal slide grooves 403 are symmetrically opened inside the L-shaped frame 2. The two movable slides 4 are slidably installed in the two horizontal slide grooves 403 respectively. By setting threads with opposite directions at both ends of the bidirectional lead screw 402, and the threads are adapted to the two movable slides 4, the two movable slides 4 can be moved in the direction of approaching or moving away when the bidirectional lead screw 402 is rotated, so as to adjust the distance between the two side guard rollers 401, so that it can adapt to the winding of steel plates of different widths.

[0063] Working principle:

[0064] The steel plate is wound up by controlling the rotation of the winding roller 101 through the drive of the steel plate winding machine 1. During the winding process, the steel plate can pass through the two guide rollers 203, which limit and guide the steel plate. At the same time, the extrusion roller 204 is pressed against the wound steel plate by the elastic force of the spring 205 to prevent the wound steel plate from sliding or misaligning. As the wound steel plate becomes thicker, the extrusion roller 204 will move upward due to the change in steel plate thickness. This allows the extrusion roller 204 to drive the movable frame 202 to move upward. The movable frame 202 can then compress the spring 205 and drive the guide roller 203 and guide rod 201 to rise. When the guide roller 203 rises, it can change the limiting and guiding height of the steel plate to adapt to the change in steel plate thickness. The side guard rollers 401 on both sides can protect the sides of the wound steel plate to prevent the steel plate from tilting to the sides during winding. The oblique offset, and by rotating the bidirectional lead screw 402, the two movable slides 4 move in opposite directions to adjust the distance between the two side rollers 401 so that they can accommodate steel plates of different widths. When the coiled steel plate reaches the corresponding thickness, the continuously rising movable frame 202 will squeeze and trigger the control switch 301, causing the control switch 301 to transmit a signal to the control module. The control module then drives the audible and visual alarm 302 to sound an alarm and controls the steel plate coiler 1 to stop operating, so as to remind the staff to replace the coiled steel plate in time. By rotating the adjusting lead screw 303, it can be driven to move the limiting slide 3 up and down in the guide slide hole 304 through the threaded engagement with the limiting slide 3, thereby adjusting the height of the control switch 301. The height of the control switch 301 can be adjusted according to the thickness of the steel plate to be coiled.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
