The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The invention relates to a novel wavy screen, which is wavy in the whole structure and is formed by combining a metal net and a vinyl net.
As shown in fig. 1 and 2, the wave screen mainly includes a screen body and an outer frame. The screen main body is formed by using a metal net and a vinyl net, and is a main part for screening materials. The outer frame is used for providing support for the screen body and is arranged at the end part of the screen body, namely the outer frame is fixedly arranged at the end part of the screen body. The structure of the screen main body is wave-shaped. In a specific implementation, the outer frame is typically made of a polyurethane material.
The screen body comprises a plurality of metal nets and a plurality of ethylene nets; the metal net and the ethylene net are sequentially stacked. Specifically, a layer of ethylene mesh is added between every two metal meshes, and the bottom end and the top end are metal meshes; that is to say, the outermost layer of the screen body is a metal mesh. The metal net and the ethylene net are combined into an integral structure after being heated and pressurized.
In a specific implementation, the metal net and the ethylene net are most commonly arranged in a way that the metal net 1 is provided with two pieces, the ethylene net 2 is provided with one piece, and the ethylene net 2 is placed between the two pieces of metal nets 1, as shown in fig. 2. Or, the metal net is provided with three pieces, the ethylene net is provided with two pieces, and the two pieces of ethylene nets are respectively arranged between the metal nets.
In the specific implementation of the invention, the sizes of the metal nets are consistent, and the size of the ethylene net is consistent with that of the metal nets; the screen cloth processed in this way is more beautiful.
In a specific implementation of the invention, the screen body is fixedly connected to the frame by glue at both ends.
The invention also discloses a manufacturing method of the novel wave screen, which is used for processing and manufacturing the wave screen; specifically, the method comprises the following steps of,
1) cutting, namely cutting the metal net and the ethylene net according to the requirements, mainly according to the size requirements of customers; and (5) reserving the cut metal net and the cut ethylene net for later use.
2) And stacking, namely stacking the metal nets and the ethylene nets in a mode of adding a layer of ethylene net between every two metal nets, and ensuring that the bottommost end and the topmost end are the metal nets. Generally, two metal nets are arranged to sandwich one ethylene net, or three metal nets are arranged to sandwich two ethylene nets.
3) And heating and pressing, namely heating and pressing the stacked screen main bodies on heating and pressing equipment. Firstly, the ethylene mesh is heated and melted by using equipment, and the metal mesh and the ethylene mesh are fused together by pressurizing. In a specific implementation, the ethylene mesh does not need to be completely melted, and the pressing operation can be performed when the ethylene mesh starts to melt.
4) And pressing the cooled net body into a wave-shaped structure. Specifically, the mesh screen is usually formed by pressing waves with gears engaged with each other, and allowing the pressed mesh body to pass through the engaged position of the gears. The gear engagement structure is shown in fig. 3.
5) And adhering the net body pressed with the waves to the outer frame by using glue.
In the specific processing, in order to improve the production efficiency and reduce the material transfer, the operation of step 2 is usually performed on the equipment of step 3, the metal net and the ethylene net are stacked on the equipment platform for heating and pressing, and the heating and pressing are directly performed after the stacking is completed.
In the specific processing, the heating and the pressurizing are simultaneously carried out in the step 3, the equipment platform for heating and laminating can be heated, and the pressure head of the equipment for heating and laminating can also be heated. The heating and pressing equipment can heat the metal net and the ethylene net simultaneously when the pressure head pressurizes the metal net and the ethylene net.
Furthermore, the step 3 of pressurizing the net body is divided into two stages, in the first stage, the pressure head slightly pressurizes the stacked net body and heats the stacked net body simultaneously, and the pressurizing of the equipment can enable the pressure head and the platform to be in close contact with the net body, so that the ethylene net can be rapidly heated and melted. In this stage, the pressure is controlled to 200N-300N to slightly melt the ethylene net, generally about 1 minute. Entering a second stage when the ethylene net begins to melt; in the stage, the pressure of a pressure head needs to be increased to enable the metal net and the ethylene net to be pressed, in the second stage, the pressure is controlled to be 800N-1200N to enable the metal net and the ethylene net to be combined into a whole, and the pressure can enable the metal nets to be combined. In the second stage, heating is performed simultaneously with the pressurization. The pressure head and the equipment platform are heating bodies, and the pressure head and the equipment platform cannot be in direct contact with the ethylene net and cannot be used for excessively melting the ethylene net generally.
The invention is a new kind of wave screen, its screen body uses the metal mesh and ethylene mesh to stack and then suppress and form, this screen has ethylene mesh structure, sieve and filter the effectual on the whole; meanwhile, the metal net structure is adopted, and the structural strength is good on the whole.
