Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of uncoiling mechanisms, and in particular to an uncoiling mechanism for a slitting machine. Background Technology
[0002] A slitting machine is a type of metal cutting equipment used for longitudinal shearing of metal strips and rewinding the slits into coils. An uncoiler is a specialized piece of equipment for leveling metal sheets, used to level uneven steel plates. Depending on the configuration, uncoilers can be integrated into uncoiling, leveling, and shearing production lines, as well as other sheet metal product production lines. The uncoiler is a crucial component of a slitting machine system.
[0003] Chinese utility model CN215745588U describes an uncoiling device for a drawing machine, which includes an uncoiling support structure. The principle is that a motor drives a threaded rod to rotate, and while the threaded rod rotates, it drives a threaded block to move, thereby pushing a connecting rod to rotate. This allows a push plate to move and support the inside of the coil.
[0004] However, in existing devices, the threaded rod and threaded block are exposed during use, making them prone to surface contamination by impurities, which affects their operation and makes cleaning difficult. Therefore, a support structure that is less susceptible to these problems was designed. Utility Model Content
[0005] The purpose of this invention is to provide an uncoiling mechanism for a slitting machine to solve the problems mentioned in the background art.
[0006] The technical solution adopted in this utility model is:
[0007] An uncoiling mechanism for a slitting machine includes: a support frame whose top is penetrated by a rotating column and rotatably connected to the rotating column; a drive mechanism disposed on one side of the support frame for driving the rotating column to rotate; a support assembly disposed inside the rotating column, the support assembly including: a motor disposed inside the rotating column; a rotating rod with one end penetrating the inner wall of the rotating column and fixedly connected to the output shaft of the motor and rotatably connected to the inner wall of the rotating column; a turntable penetrated by the rotating rod and fixedly connected to the rotating rod; a guide groove formed on the outer wall of the turntable; a sliding rod slidably disposed inside the guide groove; a connecting rod with one end penetrating the outer wall of the rotating column and connected to one end of the sliding rod; and a push plate disposed on the outer side of the rotating column, with the inner wall of the push plate connected to one end of the connecting rod.
[0008] In some embodiments, two sets of connecting rods are symmetrically arranged, each set at both ends of the slide rod.
[0009] In some embodiments, the push plate has an arc-shaped design.
[0010] In some embodiments, the support assembly further includes a cone disposed at one end of the rotating column.
[0011] In some embodiments, the push plate is provided with a limiting component, the limiting component including: a groove formed on the outer side wall of the push plate; a positioning hole formed on the inner side wall of the groove; a slider slidably disposed inside the groove; one end of an insert rod penetrating through the inner side wall of the slider and inserted into the interior of the positioning hole; a spring disposed inside the slider and connected at both ends to the inner side wall of the slider and one end of the insert rod; one end of a pull rod penetrating through the outer side wall of the slider and connected to the insert rod; and a baffle disposed at one end of the pull rod.
[0012] In some embodiments, the outer wall of the slider is in contact with the inner wall of the groove.
[0013] In some embodiments, the limiting component further includes a handle disposed at one end of the baffle.
[0014] In some embodiments, the limiting component further includes rubber pads disposed on both sides of the baffle.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] This unwinding mechanism uses a motor-controlled rotating rod to drive a turntable, which in turn rotates a slide bar inside a guide groove. This pushes a connecting rod that extends from inside the rotating column, pushing a push plate to support the roll material. Compared to existing devices where components like the slide bar are located inside the rotating column, this design is less susceptible to interference. Attached Figure Description

[0026] 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.
[0027] The current technology works by using a motor to drive a threaded rod to rotate, which in turn drives a threaded block to move, thereby pushing a connecting rod to rotate and allowing a push plate to move and support the inside of the roll material. However, in existing devices, the threaded rod and threaded block are exposed, making them prone to accumulating impurities that affect use and are also difficult to clean.
[0028] As shown in the attached figure, this embodiment of the utility model provides an unwinding mechanism for a slitting machine.
[0029] The system includes: a bracket 11 whose top is penetrated by a rotating column 12 and rotatably connected to the rotating column 12; a drive mechanism 13 disposed on one side of the bracket 11 for driving the rotating column 12 to rotate; a support assembly 2 disposed inside the rotating column 12, the support assembly 2 including: a motor 21 disposed inside the rotating column 12; a rotating rod 22 with one end penetrating the inner wall of the rotating column 12 and fixedly connected to the output shaft of the motor 21 and rotatably connected to the inner wall of the rotating column 12; a turntable 23 penetrated by the rotating rod 22 and fixedly connected to the rotating rod 22; a guide groove 24 formed on the outer wall of the turntable 23; a sliding rod 25 slidably disposed inside the guide groove 24; a connecting rod 26 with one end penetrating the outer wall of the rotating column 12 and connected to one end of the sliding rod 25; and a push plate 27 disposed on the outer side of the rotating column 12, with the inner wall of the push plate 27 connected to one end of the connecting rod 26.
[0030] Specifically, the drive mechanism 13 utilizes a drive motor located on one side of the bracket 11 to drive the turntable to rotate, causing the belt on the surface of the turntable to rotate accordingly, synchronously driving the turntable at one end of the rotating column 12 to rotate, thereby achieving the purpose of controlling the rotation of the rotating column 12.
[0031] When the roll material needs support during use, firstly, a forklift is used to lift the roll material and place it outside the rotating column 12 for support. Then, the motor 21 is connected to an external power source to drive the rotating rod 22 to rotate, which in turn drives the two turntables 23 to rotate. During rotation, the sliding rod 25 slides inside the guide groove 24, thereby pushing the connecting rod 26 out from inside the rotating column 12 and pushing the push plate 27 away from the inner wall of the roll material, stabilizing the position of the roll material and providing support. Finally, the drive mechanism 13 drives the rotating column 12 to rotate, controlling the rotation of the roll material and unrolling it.
[0032] In some embodiments, two sets of connecting rods 26 are symmetrically arranged, both located at the two ends of the slide rod 25.
[0033] Two sets are provided to better support the push plate 27.
[0034] In some embodiments, the push plate 27 has an arc-shaped design.
[0035] The curved design allows the pusher plate 27 to fit better when it comes into contact with the inner wall of the roll.
[0036] In some embodiments, the support component 2 further includes a cone 28 disposed at one end of the rotating column 12.
[0037] The design of the cone 28 makes it easier to insert when the roll sleeve is placed outside the rotating column 12.
[0038] In some embodiments, the push plate 27 is provided with a limiting component 3, the limiting component 3 including: a groove 31 formed on the outer side wall of the push plate 27; a positioning hole 32 formed on the inner side wall of the groove 31; a slider 33 slidably disposed inside the groove 31; an insertion rod 34 with one end penetrating through the inner side wall of the slider 33 and inserted into the interior of the positioning hole 32; a spring 35 disposed inside the slider 33 and connected at both ends to the inner side wall of the slider 33 and one end of the insertion rod 34; a pull rod 36 with one end penetrating through the outer side wall of the slider 33 and connected to the insertion rod 34; and a baffle 37 disposed at one end of the pull rod 36.
[0039] After supporting the roll material during use, to further restrict its position, the slider 33 can be slidably inserted into the groove 31. Then, pulling the baffle 37 causes the pull rod 36 to be pulled out from inside the slider 33, disengaging the insertion rod 34 from the positioning hole 32. Simultaneously, the spring 35 is compressed, dragging the baffle 37 to slide on the outside of the push plate 27 until it is in contact with the outside of the roll material. Releasing the baffle 37 and the spring 35 rebounds, pushing the insertion rod 34 into the positioning hole 32 to restrict the position of the slider 33. By installing the two baffles 37 on the outside of the push plate 27 in the above manner, the movement of the roll material can be restricted.
[0040] In some embodiments, the outer wall of the slider 33 is in contact with the inner wall of the groove 31.
[0041] The fitted design prevents slider 33 from wobbling after it is fixed in place.
[0042] In some embodiments, the limiting component 3 further includes a handle 38 disposed at one end of the baffle 37.
[0043] The handle 38 is designed for easy gripping and facilitates the movement of the baffle 37.
[0044] In some embodiments, the limiting component 3 further includes rubber pads 39 disposed on both sides of the baffle 37.
[0045] The design of the rubber pad 39 can better protect the baffle 37 from scratches when it comes into contact with the roll material.
[0046] 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.
