Description

Technical Field

[0001] The utility model relates to a grating height adjustment mechanism. Background Art

[0002] When producing aluminum coils, the aluminum coils need to be fed into the uncoiler and then subsequently rolled to make the strip thinner. Before feeding the aluminum coils into the uncoiler, in order to ensure that the roll of the aluminum coil can be smoothly connected with the reel of the uncoiler, the roll height of the aluminum coil needs to be detected. The height detection of the aluminum coil sleeve is generally carried out by a beam grating, which is installed on a pair of swing rods. Since the swing rod is driven down by a driving mechanism and located on the side of the aluminum coil, the roll height is detected. However, after a period of use, the detection position of the beam grating will change due to the driving mechanism, causing the detected aluminum coil sleeve to be unable to dock with the reel of the uncoiler. If the beam grating is directly adjusted on the swing rod, it is not only easy to cause the beam gratings to be unable to be accurately aligned, but also the adjustment is cumbersome and difficult, and time-consuming.

DETAILED DESCRIPTION

[0020] In order to make the above features and advantages of the present invention more understandable, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0021] refer to Figures 1 to 6

[0022] A grating height adjustment mechanism includes a frame 1, on which a horizontally arranged rotating shaft 2 is rotatably connected, and swing rods 3 are vertically fixed on both sides of the rotating shaft, and a matching opposite-radiation grating assembly 4 is installed at the upper ends of the two swing rods, and a driving mechanism for driving the rotating shaft to realize the swing rods to rotate backward is installed on the frame, thereby driving the two swing rods to be located on both sides of the aluminum coil, so that the opposite-radiation grating assembly can detect the height of the aluminum coil drum. A fixing plate 5 is arranged on the upper part of one side of the frame and located at the rear side, and an adjusting bolt 6 is vertically screwed on the fixing plate, and a locking nut 7 is screwed on the adjusting bolt. The upper end of the adjusting bolt is used to abut against the swing rod on one side after it rotates and descends, so that the swing rod abuts against the adjusting bolt after it rotates and descends backward, and the adjusting bolt is rotated when the height of the opposite-radiation grating needs to be adjusted, and the bolt is locked by the locking nut.

[0023] In this embodiment, a mounting plate 8 is fixed on the upper front side of one side of the frame, a first support rod 9 is vertically fixed on the mounting plate, and a rotation limit plate 10 that cooperates with the first support rod is fixed on the circumferential surface of one side of the rotating shaft. The first support rod cooperates with the rotation limit plate to limit the upward rotation position of the rocker arm (limit the rotation angle of the rotating shaft for rotation and reset).

[0024] In this embodiment, in order to drive the swing arm to rotate, the driving mechanism includes a seat plate 11 installed at the lower part of the other side of the frame, a driving cylinder 12 is hinged on the seat plate, and a crank 13 is fixed to the other end of the rotating shaft, and the crank is hinged to the telescopic rod of the driving cylinder. Thus, the rotating shaft is driven to rotate through the telescopic action of the driving cylinder, and the swing arm is driven to rotate.

[0025] In this embodiment, in order to detect whether the crank is in the initial position, a connecting plate 14 is installed on the upper part of the other side of the frame, and a first detection sensor 15 for detecting the initial position of the crank is installed on the connecting plate, so that when the driving cylinder rotates and resets, when the first detection sensor detects the crank, the cylinder is controlled to stop rotating.

[0026] In this embodiment, in order to better support the swing arm on the other side and ensure the stability between the two swing arms, an extension plate 16 is fixed to the upper rear side of the other side of the frame, and a second support rod 17 is fixed on the extension plate to support the swing arm on the other side after rotation and descent.

[0027] In this embodiment, the first support rod and the second support rod are elastic support rods with a certain telescopic elastic force.

[0028] In this embodiment, a vertical plate 18 is also installed on the extension plate, and a vertical long groove is provided on the vertical plate. A second detection sensor 19 is horizontally installed in the long groove so that after the swing arm rotates and drops into place, when the second detection sensor detects the swing arm on the other side, the driving cylinder is controlled to stop moving.

[0029] In this embodiment, the first detection sensor and the second detection sensor are both electrically connected to the driver of the driving cylinder via the controller.

[0030] In this embodiment, a protective baffle 20 is further provided between the two upright posts of the frame.

[0031] Working principle: When the aluminum coil is sent to the inspection station through the conveying mechanism, the driving cylinder drives the rotating shaft to drive the swing rod to rotate backward, so that the two swing rods are located on both sides of the aluminum coil; when the second detection sensor detects the swing rod, the cylinder stops moving, and the swing rod is supported on the upper end of the adjusting bolt and the second support rod. The upper end position of the aluminum coil is detected by the opposite beam grating component. If the opposite beam grating components can be connected at this time, it means that the height of the aluminum coil is sufficient, the swing rod can be rotated and reset, and the aluminum coil can be sent to the unwinder to dock with the reel; if the opposite beam grating components cannot be connected, it means that the position of the aluminum coil is low, and the conveying mechanism is required to lift the aluminum coil. When the staff finds that the height of the aluminum coil is sufficient, but the height of the detection position of the opposite beam grating component is insufficient, the height of the detection position of the opposite beam grating component can be quickly adjusted by rotating the adjusting bolt (raising or lowering the adjusting bolt), avoiding the direct adjustment of the position of the opposite beam grating component on the swing rod, reducing the difficulty and tediousness of adjustment.

[0032] If the words "first", "second" and the like are used in the above-mentioned utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above-mentioned words have no special meaning.

[0033] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the fixed connection to each other can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0034] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0035] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0036] The above description is only a preferred embodiment of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the present invention.
