[0002] An uncoiler is a specialized piece of equipment for leveling metal sheets. The machine body is a welded box-shaped structure. A variable frequency speed-regulating motor drives the drum shaft through a gearbox to provide the main force for the uncoiler. The uncoiler is a specialized piece of equipment for leveling metal sheets. It is used to level steel plates and uneven plates. It can be configured to form an uncoiler, leveling, and shearing production line and other sheet metal product production lines.

[0003] According to the specification of the Chinese utility model publication number "CN219282290U", "a braking device for an uncoiler includes a base plate, a bracket is fixedly connected to the top surface of the base plate, a support mechanism is provided on the right side of the bracket, an uncoiler mechanism is provided on the left side of the support mechanism, and the uncoiler mechanism includes a power unit".

[0004] According to the aforementioned patent, two sets of brakes are set to squeeze and rub against the unwinding mechanism, which has a braking effect on the unwinding mechanism. However, after long-term use, the brake parts will wear down and need to be replaced. However, when replacing the brake parts, the machine needs to be stopped, which affects the work efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a braking device for an uncoiler to solve the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A braking device for an uncoiler includes a braking assembly comprising: a driving mechanism disposed on the outer side of a mounting frame; an uncoiler mechanism rotatably mounted on the mounting frame; a frame disposed on the mounting frame; a through slot formed at the bottom of the frame; a fixing block disposed on the inner side of the frame; a motor symmetrically disposed on the frame; a lead screw rotatably disposed on the fixing block and connected to the motor; a movable block symmetrically disposed on the inner side of the frame and threadedly connected to the lead screw; a slider disposed at the bottom of the movable block and passing through the through slot; a brake pad disposed at the bottom of the slider; a slot formed at the top of the brake pad; and a screw disposed on the brake pad and threadedly connected to the brake pad.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] When the brake pads are worn out and need replacement, the motor rotates in reverse, causing the brake pads to move away from the winding mechanism. Then, the motor on the other side is started, causing the brake pad on the other side to move and contact the unwinding mechanism, thus braking the unwinding mechanism. Then, the screw is turned to release the brake pad and remove it. The new brake pad is then connected to the slider, and the screw is turned to fix the brake pad. This device can brake the unwinding mechanism by setting two sets of brake pads, allowing brake pad replacement without stopping the machine, making it more convenient to use and increasing work efficiency.

Therefore, they should not be construed as limitations on this utility model.

[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] In the current technology, two sets of brakes are set up to squeeze and rub against the uncoiling mechanism, which has a braking effect on the uncoiling mechanism. However, after long-term use, the brake parts will wear down and need to be replaced. However, when replacing the brake parts, the machine needs to be stopped, which affects the work efficiency.

[0027] like Figure 1-3As shown, this utility model embodiment provides a braking device for an uncoiler, including a braking assembly 1. The braking assembly 1 includes: a driving mechanism 12 disposed on the outer side of a mounting frame 11; an uncoiler mechanism 13 rotatably disposed on the mounting frame 11; a frame 14 disposed on the mounting frame 11; a through groove 141 opened at the bottom of the frame 14; a fixing block 15 disposed on the inner side of the frame 14; a motor 16 symmetrically disposed on the frame 14; a lead screw 161 rotatably disposed on the fixing block 15 and connected to the motor 16; a movable block 17 symmetrically disposed on the inner side of the frame 14 and threadedly connected to the lead screw 161; a slider 171 disposed at the bottom of the movable block 17 and passing through the through groove 141; a brake pad 18 disposed at the bottom of the slider 171; a slot 181 opened at the top of the brake pad 18; and a screw 19 disposed on the brake pad 18 and threadedly connected to the brake pad 18.

[0028] The unwinding mechanism 13 is driven by the drive mechanism 12 to rotate and wind up the object. This mechanism is existing technology and will not be described in detail here. When it is necessary to brake the unwinding mechanism 13, the motor 16 is first started by an external power source, which drives the lead screw 161 to rotate. This causes the movable block 17, which is threadedly connected to the lead screw 161, to move inside the frame 14, and drives the brake pad 18 to move. The brake pad 18 then contacts the unwinding mechanism 13, braking the unwinding mechanism 13 through friction. When the brake pad 18 is worn out and needs to be replaced, the motor 16 is reversed, causing the brake pad 18 to move away from the unwinding mechanism 13. Then, the other side of the motor is started. The machine 16 causes the brake pad 18 on the other side to move and come into contact with the unwinding mechanism 13, thus braking the unwinding mechanism 13. Then, the screw 19, which is threadedly connected to the brake pad 18, is rotated to unscrew the screw 19 from the inside of the slider 171, releasing the brake pad 18 from the slider 171 and separating the slider 171 from the slot 181. In this way, the brake pad 18 can be removed, and a new brake pad 18 is connected to the slider 171. Then, the screw 19 is rotated to fix the brake pad 18. This device can brake the unwinding mechanism 13 by setting two sets of brake pads 18, and the brake pads 18 can be replaced without stopping the machine, making it more convenient to use and increasing work efficiency.

[0029] Furthermore, an auxiliary component 2 is provided on the brake pad 18, the auxiliary component 2 including a spring 21 disposed inside the slot 181.

[0030] A spring 21 is provided at the bottom inner side of the slot 181. After the brake pad 18 is released from its fixed position, the spring 21 will return to its original position and pop out the brake pad 18, making it easier to remove the brake pad 18.

[0031] Furthermore, the auxiliary component 2 also includes: inclined grooves 22 symmetrically formed at the bottom of the slider 171.

[0032] symmetrical inclined grooves 22 are made on both sides of the slider 171. When the slider 171 is connected to the slot 181, the inclined grooves 22 can guide the slider 171, making it easier for the slider 171 to connect with the slot 181.

[0033] Furthermore, the auxiliary component 2 also includes a base plate 23 symmetrically arranged on the mounting bracket 11.

[0034] A base plate 23 is symmetrically arranged on one side of the mounting bracket 11, so that the brake pad 18 can abut against the base plate 23, which can increase the structural strength of the brake pad 18.

[0035] Furthermore, the auxiliary component 2 also includes pulleys 24 symmetrically arranged at the bottom of the brake pads 18.

[0036] Pulleys 24 are symmetrically arranged at the bottom of the brake pad 18. This reduces the friction between the brake pad 18 and the base plate 23 when the brake pad 18 moves, making the movement of the brake pad 18 more convenient.

[0037] Furthermore, the auxiliary component 2 also includes: a slide 25 symmetrically formed on the top of the base plate 23.

[0038] The top of the base plate 23 is symmetrically provided with grooves 25, which allows the pulley 24 to slide inside the grooves 25, making the movement of the brake pad 18 more stable.

[0039] Furthermore, the frame 14 is connected to the mounting bracket 11 by bolts.

[0040] The frame 14 and the mounting bracket 11 are bolted together, so that when the internal parts of the frame 14 are damaged or deformed, the frame 14 can be easily disassembled and replaced.

[0041] Furthermore, the auxiliary component 2 also includes a limiting plate 26 disposed on the top of the mounting bracket 11.

[0042] A limiting plate 26 is provided on the top of the mounting bracket 11 to limit the frame 14, thereby preventing the frame 14 from tilting during installation and making the installation more convenient.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
