Description

Technical Field

[0001] The utility model relates to a roller placing mechanism with a belt pressing function. Background Art

[0002] Aluminum coils need to be rolled several times during the production process to achieve the required thickness. Aluminum coils are generally placed on the tensioning shaft of the uncoiler, and the strip head of the aluminum coil passes through the guide roller and is sent into the rolling mill. However, after the strip head of the aluminum coil passes through the guide roller, the strip head of the aluminum coil will be tilted upward, which is not conducive to the strip head of the aluminum coil entering the rolling mill. And because the uncoiler is slidably installed on the base, there will be wear and gap between the transverse slide groove and the transverse guide rail on the uncoiler base shell, which affects the sliding adjustment of the uncoiler.

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 4

[0022] A roll-release mechanism with a belt pressing function comprises a base 10, on which a decoiler 20 driven by a first driving mechanism to realize lateral adjustment is slidably connected, a fixed frame 30 is arranged above the tensioning shaft 21 of the decoiler, a pair of guide rollers are arranged laterally on the rear side of the fixed frame, namely, a first guide roller 31 located at the lower side and a second guide roller 32 located above the front side of the first guide roller, a channel 33 for the strip head of the aluminum coil to pass through is formed between the pair of guide rollers, and a pressing roller 34 driven by a second driving mechanism to realize downward pressing is arranged on the fixed frame. The aluminum coil strip head passing through the channel is pressed downward by the pressing roller, so that the aluminum coil strip head can enter the rolling mill better.

[0023] In this embodiment, in order to adjust the position of the uncoiler, the first driving mechanism includes a fixed seat 11 connected to the base, and a first oil cylinder 12 arranged laterally is hinged on the fixed seat, and the telescopic rod of the first oil cylinder is hinged to the seat shell of the uncoiler.

[0024] In this embodiment, in order to better control the moving position of the uncoiler, a resistance scale 13 connected to one side end of the seat shell of the uncoiler is installed on one side of the base.

[0025] The lead feeding channel of the aluminum coil needs to be centered (i.e. aligned) to better achieve subsequent rolling. Since the installation position of the aluminum coil on the tensioning shaft can be obtained through the feeding mechanism, the lateral movement position of the tensioning shaft can be obtained through the resistance scale. The resistance scale feeds back the position information to the controller of the first oil cylinder, controls the first oil cylinder to extend and retract, thereby driving the unwinder to move the tensioning shaft horizontally and adjust the center position of the aluminum coil.

[0026] In this embodiment, the second driving mechanism includes a rotating frame 35 whose front lower side is hinged to the fixed frame, the front lower side of the rotating frame is rotatably connected to the two sides of the second guide roller, the pressure roller is rotatably connected to the rear of the rotating frame, and the front of the fixed frame is hinged with a telescopic rod through a hinge seat 36 and a second oil cylinder 38 which is hinged to the connecting seat 37 at the upper front side of the rotating frame. Thus, the pressure roller is lowered and raised by the extension and contraction of the second oil cylinder to adjust the position of the aluminum coil head.

[0027] In this embodiment, a pair of transverse guide rails 14 are provided on the base, a pair of transverse slide grooves 22 matching with the transverse guide rails are provided at the lower part of the base shell of the uncoiler, and a sliding gap adjustment mechanism 40 is provided on one of the transverse slide grooves. Since the transverse guide rails and the transverse slide grooves will wear after being used for a certain period of time, a sliding gap is formed, and the sliding gap adjustment mechanism can be used to adjust the gap and reduce the gap.

[0028] In this embodiment, the sliding gap adjustment mechanism includes an L-shaped fixed plate 41 fixed on both side ends of the uncoiler, and the longitudinal plates of the L-shaped fixed plate are provided with adjusting screws 42 that can be adjusted laterally. One end of the adjusting screw is longitudinally slidably connected with a wedge block 42, one end of the wedge block extends into the gap between the transverse slide groove and the transverse guide rail and the flat side is in contact with the transverse guide rail, and the other end of the wedge block is provided with a longitudinal T-slot 431 that cooperates with the raised portion at one end of the adjusting screw.

[0029] By adjusting the position of the adjusting bolt, the position of the wedge block extending into the transverse chute is controlled so that one side of the transverse guide rail can be closely attached to the transverse chute to reduce the gap. For example, if the plane side of the wedge block is in contact with the front side of the transverse guide rail, the position of the wedge block extending into the transverse chute can be adjusted so that the rear side of the transverse guide rail can be close to the rear side of the transverse chute to reduce the gap between the two.

[0030] In this embodiment, in order to adjust the position of the wedge, the adjusting screw rod passes through the longitudinal plate of the L-shaped fixing plate horizontally, and the adjusting screw rod is screwed with adjusting nuts 44 located on both sides of the longitudinal plate. When adjusting the position of the wedge, the wedges connected by the two L-shaped fixing plates are adjusted at the same time.

[0031] 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.

[0032] 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).

[0033] 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.

[0034] 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.

[0035] 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.
