Description

Technical Field

[0001] This utility model particularly relates to a metal strip rolling apparatus. Background Technology

[0002] In continuous metal strip rolling production lines, to prevent the strip from shifting laterally during stacking after discharge, vertical plates (angle steel or nylon plates) are fixedly welded to both sides of the rack as baffles. These rigid contact plates confine the strip edges within a set width. As the strip stacking height gradually increases, some production lines install an additional spring button on the top of the baffle. When the stack reaches the spring button, an alarm signal is triggered, providing a "full material reminder." However, this structure has the following problems:

[0003] A 1-3mm gap must be maintained between the baffle and the strip; otherwise, the thin strip is easily scratched. If the gap is too large, the strip will still spur out under the action of high-speed discharge airflow, causing the stack to tilt or even collapse. In addition, existing technologies usually only use a single-point detection method with a "height-spring button": when the stack height reaches the set value, the strip's own weight compresses the spring to trigger the button alarm. If edge deviation occurs first, the strip will collapse before it presses the button, resulting in a missed alarm. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a metal strip rolling apparatus.

[0005] To solve the aforementioned technical problems, this utility model adopts the following technical solution:

[0006] A metal strip rolling apparatus includes a mounting frame. Upper and lower pressure rollers are vertically spaced on the mounting frame. The mounting frame has a receiving portion for receiving the rolled metal strip. A pair of magnetic limiting members are symmetrically arranged on both sides of the mounting frame. A movable frame is movably mounted on the upper end of each magnetic limiting member. An elastic member is positioned between the upper end of the mounting frame and the movable frame. A button is located on the side of the mounting frame. The metal strip is confined within the space formed by the two magnetic limiting members and the mounting frame. When the metal strip is stacked to a set height, the movable frame is pushed upwards and compresses the elastic member until the movable frame triggers the button to issue an alarm.

[0007] Preferably, the elastic element is a spring.

[0008] Preferably, the lower pressure roller is rotatably mounted on the mounting frame, and a drive wheel is rotatably mounted on the mounting frame. The drive wheel and the lower pressure roller are connected by a first belt drive. The upper pressure roller is provided with a first toothed disc, and the lower pressure roller is provided with a second toothed disc that meshes with the first toothed disc. A rotary motor is connected to the drive wheel.

[0009] Preferably, the mounting bracket is provided with a driven wheel, and the driven wheel and the driving wheel are connected by a second belt drive. An accumulator is connected to the driven wheel.

[0010] Preferably, a limiting groove is provided on the moving frame; when the stacked metal strips push the moving frame to move upward, the button is pressed by the moving frame under the guidance of the limiting groove, thereby triggering an alarm.

[0011] The beneficial effects of this utility model are:

[0012] This invention uses a magnetic limiting component to hold the strip edge in place, preventing deviation with zero gap; it also features a dual alarm system: the accumulator first issues a warning after a preset number of cycles, and then a button confirms the alarm. Even with insufficient light material, the spring-loaded mechanism is not affected, preventing missed alarms and allowing sufficient time for material replacement, completely avoiding the tipping over of thin strip stacks.

A movable frame 6 is movably disposed at the upper end of each magnetic limiting member 5. An elastic member 7 is disposed between the upper end of the mounting frame 1 and the movable frame 6. A button 8 is provided on the side of the mounting frame 1. The metal strip 1-1 is confined within the space formed by the two magnetic limiting members 5 and the mounting frame 1. When the metal strip 1-1 is stacked to a set height, the movable frame 6 is pushed upwards and the elastic member 7 is compressed until the movable frame 6 triggers the button 8 to issue an alarm.

[0023] Furthermore, the elastic element 7 is a spring.

[0024] Furthermore, the lower pressure roller 3 is rotatably mounted on the mounting frame 1, and the mounting frame 1 is rotatably mounted on the drive wheel 10. The drive wheel 10 and the lower pressure roller 3 are connected by a first belt 103. The upper pressure roller 2 is provided with a first toothed disc 21, and the lower pressure roller 3 is provided with a second toothed disc 31 that meshes with the first toothed disc 21. The drive wheel 10 is connected to a rotary motor 32.

[0025] Furthermore, the mounting bracket 1 is provided with a driven wheel 9, and the driven wheel 9 and the driving wheel 10 are connected by a second belt 90. An accumulator 901 is connected to the driven wheel 9.

[0026] Furthermore, a limiting groove 61 is provided on the movable frame 6; when the stacked metal strips 1-1 push the movable frame 6 to move upward, the button 8 is pressed by the movable frame 6 under the guidance of the limiting groove 61, thereby triggering an alarm.

[0027] The working principle of this utility model is as follows:

[0028] A metal strip rolling apparatus includes a mounting frame 1. Upper pressure rollers 2 and lower pressure rollers 3 are vertically spaced on the mounting frame 1, and a receiving portion 4 is provided on the mounting frame 1. A pair of magnetic limiting members 5 are symmetrically arranged on both sides of the mounting frame 1. A movable frame 6 is movably mounted at the upper end of the magnetic limiting member 5, and a spring 7 is provided between the movable frame 6 and the upper end of the mounting frame 1. A button 8 is provided on the side of the mounting frame 1, and the button 8 is electrically connected to an external alarm.

[0029] During operation, the rotary motor 32 drives the drive wheel 10 to rotate, which in turn drives the lower pressure roller 3 to rotate via the first belt 103. Simultaneously, the first gear disc 21 meshes with the second gear disc 31, causing the upper pressure roller 2 to rotate synchronously. The metal strip 1-1 is placed between the upper pressure roller 2 and the lower pressure roller 3. As the upper and lower pressure rollers rotate in opposite directions, the metal strip 1-1 is rolled. After rolling, the metal strip 1-1 is placed on the receiving part 4 manually or by a robotic arm. The magnetic limiting component 5 limits and attracts the metal strip 1-1 to prevent deviation. As the metal strip 1-1 is continuously stacked, when the height reaches a set value, the stacked metal strip 1-1 pushes the moving frame 6 upward, compressing the spring 7. The limiting groove 61 on the moving frame 6 guides the button 8, causing it to be pressed, thereby triggering an alarm that emits an audible and visual alarm, reminding the operator to remove the metal strip 1-1 in time to avoid excessive stacking. After the metal strip 1-1 is removed, the spring recovers its deformation and moves the moving frame 6 back to its initial position.

[0030] Based on the above technical solution, this application also provides a driven wheel 9 on the mounting frame 1, and a second belt 90 is provided between the driven wheel 9 and the driving wheel 10 for transmission connection. An accumulator 901 is provided on the driven wheel 9, and the accumulator 901 is coaxially fixed to the driven wheel 9 for accumulating the number of rotations of the driven wheel 9. The accumulator 901 has a preset rotation threshold N. When the accumulated rotation reaches N, an alarm signal is issued. The alarm signal can be an audible and visual alarm electrically connected to the accumulator 901.

[0031] The application scenario of this utility model is as follows: Because the metal strip 1-1 is relatively thin, its weight may not be sufficient when stacked to the set height, and the spring may not be fully compressed, potentially causing the metal strip 1-1 to tip over. Therefore, a dual alarm structure is designed. Based on experimental measurements of the number of rotations of the driven wheel 9, the stacking amount of the metal strip 1-1 is determined. When the accumulator 901 reaches the preset rotation number, a warning signal is issued, prompting the operator that "the stacking amount of metal strip 1-1 is approaching the critical point; please prepare to move the material." At this point, the button has not yet been activated. If the stacking continues to increase until the spring is fully compressed and triggers button 8, a second alarm is triggered. This prevents missed alarms due to "light material not being able to compress the spring" and provides operators with ample time for material movement through early warning, completely eliminating the risk of thin strip stacking tipping over.

[0032] This invention uses a magnetic limiting component to hold the strip edge in place, preventing deviation with zero gap; it also features a dual alarm system: the accumulator first issues a warning after a preset number of cycles, and then a button confirms the alarm. Even with insufficient light material, the spring-loaded mechanism is not affected, preventing missed alarms and allowing sufficient time for material replacement, completely avoiding the tipping over of thin strip stacks.

[0033] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
