Laravel file upload incorrect name in input field

While updating the record, I have created an option to replace the image using file upload, but when doing so in $request->file('headerbanner'), it is getting saved in DB as /tmp/phpCccApH

Controller Code :

public function update(Request $request, $id)
{ 

    $clientnewstore = Clientusers::find($id); 
    if($request->hasFile('headerbanner')) {

        $headerbanner = $request->file('headerbanner');
        $mod_headerbanner= date('Y-m-d').'-'.'MQ'.rand(1, 999).'-'.$headerbanner->getClientOriginalName(); 
        $headerbanner->storeAs(public_path().'banners',$mod_headerbanner);
        $request['headerbanner'] = $mod_headerbanner;  

    }


    if($request->hasFile('footerbanner')) {            
        $footerbanner = $request->file('footerbanner');
        $mod_footerbanner= date('Y-m-d').'-'.'MQ'.rand(1, 999).'-'.$footerbanner->getClientOriginalName();
        $footerbanner->storeAs('banners',$mod_footerbanner);
        $request['footerbanner'] = $mod_footerbanner;
    }




    Clientusers::find($id)->update($request->all());

   $request->session()->flash('message','Record Successfully Updated');
    return redirect('/user_accounts');
}

HTML file

        <form action="/user_accounts" method="POST" enctype="multipart/form-data">
                   
            <h4> Header / Footer Settings</h4>
            <div class="form-group row py-2">
                <div class="col-sm-6 pr-4">
                    <label for="headerbanner">Header Banner</label>
                    <input type="file" class="form-control"  id="headerbanner"  name="headerbanner"    />
                </div> 

                <div class="col-sm-6">  
                    <label for="footerbanner">Footer Banner</label>
                    <input type="file" class="form-control"  id="footerbanner" class="form-control"   name="footerbanner" >
                </div>    
            </div>   
      <div class="float-right text-right">
         <button type="submit" class="btn btn-success float-right">
             <i class="fas fa-check px-2"></i> Save
         </button>
      </div>
